Guide system release device for vehicle impact testing
View Patent ↗A guide release system for use in an impact test of a motor vehicle includes a first guide releasably coupled to a first portion of the motor vehicle to guide the first portion of the motor vehicle towards a test barrier. The system also includes a second guide releasably coupled to a second portion of the motor vehicle to guide the second portion of the motor vehicle towards the test barrier. The second guide is displaced a distance from the first guide. The system further includes an actuator that releases the first guide and the second guide substantially simultaneously to enable the motor vehicle to freely contact the test barrier.
1. A guide release system for use in an impact test of a motor vehicle comprising:
a first guide releasably coupled to a first portion of the motor vehicle to guide the first portion of the motor vehicle towards a test barrier;
a second guide releasably coupled to a second portion of the motor vehicle to guide the second portion of the motor vehicle towards the test barrier, the second guide displaced a distance from the first guide; and
an actuator that releases the first guide and the second guide substantially simultaneously to enable the motor vehicle to freely contact the test barrier.
2. The system of claim 1 , further comprising a first swing arm coupled to the first portion of the motor vehicle and a second swing arm coupled to the second portion of the motor vehicle, the first swing arm releasably coupled to the first guide and the second swing arm releasably coupled to the second guide.
3. The system of claim 2 , wherein the first guide and the second guide are configured to be driven by an impact system to drive the first portion and the second portion of the motor vehicle toward the test barrier.
4. The system of claim 3 , wherein the impact system includes a track and a stop, with the first guide and second guide each received in the track, and the actuator contacting the stop to release the first swing arm from the first guide and the second swing arm from the second guide.
5. The system of claim 4 , wherein the actuator includes a compressible member slideably coupled to the first guide that contacts the stop, which compresses the compressible member to release the first swing arm and second swing arm.
6. The system of claim 5 , further comprising a rod that couples the first guide to the second guide, the rod adjustable to enable the first guide to move relative to the second guide, and the rod enables a transfer of force from the contact between the compressible member and the stop from the first guide to the second guide to enable the substantially simultaneous release of the first swing arm and the second swing arm from the first guide and the second guide.
7. The system of claim 6 , wherein the first guide and the second guide each include a slideable member fixed from movement by a shear pin, and when fixed, each slideable member couples the respective first guide and second guide to the first swing arm and second swing arm, and when released by the shear pin, each slideable member forces the respective first swing arm and second swing arm out of engagement with the respective first guide and the second guide.
8. The system of claim 7 , wherein the contact between the compressible member and the stop shears the shear pin in both the first guide and the second guide to release the slideable member so that each slideable member releases the first swing arm and second swing arm substantially simultaneously.
9. A guide release system for use in an impact test of a motor vehicle comprising:
a first guide releasably coupled to a first portion of the motor vehicle to guide the first portion of the motor vehicle towards a test barrier;
a second guide releasably coupled to a second portion of the motor vehicle to guide the second portion of the motor vehicle towards the test barrier;
a rod that couples the first guide to the second guide, the rod adjustable to enable the first guide to move relative to the second guide; and
an actuator that is adapted to contact a stop to release the first guide and the second guide substantially simultaneously to enable the motor vehicle to freely contact the test barrier.
10. The system of claim 9 , further comprising a first swing arm coupled to the first portion of the motor vehicle and a second swing arm coupled to the second portion of the motor vehicle, the first swing arm releasably coupled to the first guide and the second swing arm releasably coupled to the second guide.
11. The system of claim 10 , wherein the first guide and the second guide are configured to be driven by an impact system to drive the first portion and the second portion of the motor vehicle toward the test barrier, and the impact system includes a track that receives the first guide and second guide to drive the first guide and second guide towards the test barrier.
12. The system of claim 11 , wherein the impact system further comprises a stop, and the actuator further comprises a compressible member slideably coupled to the first guide that contacts the stop to release the first guide and the second guide through the compression of the compressible member.
13. The system of claim 12 , wherein the rod enables a transfer of force from the contact between the compressible member and the stop from the first guide to the second guide to enable the substantially simultaneous release of the first swing arm and the second swing arm from the first guide and the second guide.
14. The system of claim 13 , wherein the first guide and the second guide each include a slideable member fixed from movement by a shear pin, and when fixed, each slideable member couples the respective first guide and second guide to the first swing arm and second swing arm, and when released by the shear pin, each slideable member forces the respective first swing arm and second swing arm out of engagement with the respective first guide and the second guide.
15. The system of claim 14 , wherein the contact between the compressible member and the stop shears the shear pin in both the first guide and the second guide to release the slideable member so that each slideable member releases the first swing arm and second swing arm substantially simultaneously.
16. A guide release system for use in an impact test of a motor vehicle comprising:
a motor vehicle having a front end and a rear end, a first swing arm coupled to the front end and a second swing arm attached to the rear end;
a first guide releasably coupled to the first swing arm to guide the front end of the motor vehicle towards a test barrier;
a second guide releasably coupled to the second swing arm to guide the rear end of the motor vehicle towards the test barrier;
a rod that couples the first guide to the second guide, the rod adjustable to enable the first guide to move relative to the second guide; and
an actuator that releases the first guide and the second guide substantially simultaneously to enable the motor vehicle to freely contact the test barrier.
17. The system of claim 16 , wherein the first guide and the second guide are configured to be driven by an impact system to drive the first portion and the second portion of the motor vehicle towards the test barrier, and the impact system includes a track that receives the first guide and second guide to drive the first guide and second guide towards the test barrier.
18. The system of claim 17 , wherein the impact system further comprises a stop, and the actuator further comprises a compressible member slideably coupled to the first guide that contacts the stop to release the first swing arm, with the rod operable to enable a transfer of force from the contact between the compressible member and the stop from the first guide to the second guide to enable the substantially simultaneous release of the first swing arm and the second swing arm from the first guide and the second guide.
19. The system of claim 18 , wherein the first guide and the second guide each include a slideable member fixed from movement by a shear pin, and when fixed, each slideable member couples the respective first guide and second guide to the first swing arm and second swing arm, and when released by the shear pin, each slideable member forces the respective first swing arm and second swing arm out of engagement with the respective first guide and the second guide.
20. The system of claim 19 , wherein the contact between the compressible member and the stop shears the shear pin in both the first guide and the second guide to release the slideable member so that each slideable member releases the first swing arm and second swing arm substantially simultaneously.
