Modular external frame for mobile computing devices
A mobile computing device includes: a device housing including a base, a perimeter wall extending from the base to a perimeter upper edge and having a forward section and a rear section, and an external frame member including: (i) a U-shaped wall removably affixed to the forward section of the perimeter wall and terminating at the rear section of the perimeter wall; and (ii) a retaining bezel extending from the U-shaped wall over the perimeter upper edge.
1. A mobile computing device, comprising:
a device housing including a base, a perimeter wall extending from the base to a perimeter upper edge and having a forward section and a rear section; and
an external frame member including:
(i) a U-shaped wall removably affixed to the forward section of the perimeter wall and terminating at the rear section of the perimeter wall; and
(ii) a retaining bezel extending from the U-shaped wall over the perimeter upper edge of the perimeter wall to retain a display module cover of the mobile computing device against the device housing.
2. The mobile computing device of claim 1 , further comprising:
a keypad seat within the rear section of the perimeter wall adjacent to the forward section; and
a keypad module supported adjacent to the perimeter upper edge by the keypad seat.
3. The mobile computing device of claim 1 , wherein the external frame member comprises:
a forward segment having opposing ends defining corners of the U-shaped wall; and
a pair of side segments each extending from the corners to respective terminating ends.
4. The mobile computing device of claim 3 , wherein the external frame member further comprises a shock-absorbing bumper at each of the corners.
5. The mobile computing device of claim 3 , wherein the external frame member further comprises an additional shock-absorbing bumper at each of the terminating ends.
6. The mobile computing device of claim 4 , wherein the segments include a first material, and the bumpers include a second material.
7. The mobile computing device of claim 3 , wherein the corners are resiliently deformable to increase a distance between the terminating ends.
8. The mobile computing device of claim 1 , wherein the external frame member includes an aperture for receiving a fastener therethrough to engage with the perimeter wall.
9. The mobile computing device of claim 1 , wherein the external frame member includes a ridge on an inner surface thereof, the ridge configured to engage with a corresponding channel on the forward section of the perimeter wall.
10. The mobile computing device of claim 1 , further comprising a display seat within the forward section of the perimeter wall.
11. The mobile computing device of claim 1 , further comprising a display module including a display assembly supported adjacent to the perimeter upper edge by a display seat.
12. The mobile computing device of claim 11 , wherein the display seat is disposed within the forward section of the perimeter wall.
13. The mobile computing device of claim 11 , wherein the display module cover is overlaid on the display assembly.
