Structure for mounting radar
View Patent ↗In a structure for mounting a radar, a cross linking member vertically connects two width-across members aligned in a front-to-rear direction of a vehicle. A fixing member is fixed to the cross linking member. The fixing member includes a fixing part fixed to the cross linking member, a supporting part that supports a radar device, a deformable part. The deformable part has a shape connecting the fixing part and the supporting part and bends and deforms to absorb shock when an external force is input into the radar device.
1. A structure for mounting a radar comprising:
a cross linking member that vertically connects two width-across members aligned in a front-to-rear direction of a vehicle; and
a fixing member attached to the cross linking member and extending in a forward direction of a vehicle from the cross linking member, the fixing member including,
a fixing part fixed to the cross linking member,
a first deformable portion extending in the forward direction of the vehicle from one edge of the fixing part and having a first front end,
a second deformable portion extending in the forward direction from another edge of the fixing part and having a second front end spaced apart from the first front end,
a first supporting part provided at the first front end, and
a second supporting part provided at the second front end, the first and second deformable portions supporting a radar device,
wherein the first deformable portion is formed into a shape planar symmetric to the second deformable portion and the first and second deformable portions define an opening at a forward end and configured to bend and deform to absorb shock when an external force is input into the radar device.
2. The structure for mounting a radar according to claim 1 , wherein each of the first and second deformable parts includes:
an inclined face in a shape of a flat face inclined to the fixing part; and
a vertical face in a shape of a flat face that is inclined to the inclined face and perpendicular to the supporting part.
3. The structure for mounting a radar according to claim 1 , wherein each of the first deformable portion and the second deformable portion is formed into a bifurcated shape being planar symmetric with respect to an imaginary orthogonal plane perpendicular to imaginary symmetric plane of the first deformable portion and the second deformable portion.
4. The structure for mounting a radar according to claim 1 , wherein the first deformable portion and the second deformable portion oppose each other in a width direction of the vehicle.
5. The structure for mounting a radar according to claim 2 , wherein that the first deformable portion and the second deformable portion oppose each other in a width direction of the vehicle.
6. The structure for mounting a radar according to claim 1 , wherein the first and second deformable portions have a lower stiffness against external force in the front-to-rear direction of the vehicle than a stiffness of the cross linking member against external force in the front-to-rear direction of the vehicle.
7. The structure for mounting a radar according to claim 1 , further comprising:
a protecting member that comprises:
a first mounting part to be installed to the supporting part;
a second mounting part that mounts thereon the radar device; and
a guard part that protrudes outwards in the front-to-rear direction of the vehicle further than the radar device.
8. The structure for mounting a radar according to claim 7 , wherein two of the guard parts are each disposed so as to horizontally extend along one of the top-edge face and the bottom-edge face of the radar device.
9. The structure for mounting a radar according to claim 7 , the protecting member comprises a connecting part that connects the first mounting part and the second mounting part in the front-to-rear direction of the vehicle.
10. The structure for mounting a radar according to claim 7 , wherein the protecting member has a higher stiffness against external force in the front-to-rear direction of the vehicle than a stiffness against the external force in the front-to-rear of the fixing member.
