Abstract

According to some embodiments, before an M.2 compatible module or device is mounted onto a data processing system that operates an autonomous driving vehicle (ADV), the M.2 module is placed onto a tray device to increase the stiffness of the M.2 module. The tray device containing the M.2 module is then mounted on a board or motherboard of the data processing system. Since the M.2 module is placed on the tray device, the overall stiffness has been significantly increased, which can sustain the physical impact on the M.2 module due to the physical movement and oscillation during the autonomous driving of the ADV. In addition, the tray device also provides suspension effect on the M.2 module during the movement of the ADV. As a result, the M.2 module would not easily damaged during the autonomous driving.

Dependent claims

A tray device to retain an M.2 module used in an autonomous driving vehicle, the tray device comprising:

a baseboard configured in a relatively rectangular shape having a first and second longitudinal edges and a first and second lateral edges;
a first guardrail disposed on a top surface of the baseboard along the first longitudinal edge;
a second guardrail disposed on the top surface of the baseboard along the second longitudinal edge, wherein the first and second guardrails are to keep an M.2 module in between and supported by the top surface of the baseboard, while allowing the M.2 module to extend beyond the first and second lateral edges;
and
a riser member disposed on a bottom surface of the baseboard, wherein when the M.2 module is mounted together with the tray device on a motherboard of a data processing system within an autonomous driving vehicle, the riser member is configured to raise the tray device above the motherboard to prevent the baseboard from applying a pressure that may adversely affect an electronic component mounted on the motherboard and underneath the tray device.
