[0002] With the continuous development of current autonomous driving technology, the level of autonomous driving is constantly improving, the functions of automotive electronics and software are increasing and becoming more complex, and traffic accidents occur from time to time. In order to make a clear judgment on the responsibility for the accident, current regulations will gradually propose that high-level autonomous driving vehicles must be equipped with a data recording system, in which the autonomous driving data recording system controller occupies a core position in this system. Due to the complexity of the real road environment and the increasing number of sensors, there are greater requirements for the memory size of the recording system. Considering the occurrence of an accident, in order to facilitate the timely extraction and analysis of data, an external mobile hard disk has become a more suitable and convenient solution. However, in the prior art, there is no fixed structure that can effectively fix the external mobile hard disk. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions: an external hard disk fixing structure of an autonomous driving data recording system controller, characterized in that it includes a controller housing, a fixed structure body for placing the hard disk is installed above the controller housing, and the fixed structure body is composed of an upper U-shaped bracket and a lower U-shaped bracket which are stacked and fixed to each other; at least one elastic support is provided at the bottom of the upper U-shaped bracket.

Under the condition of ensuring the ultimate cumulative tolerance, the upper end surface of the spring plunger is not higher than the upper plane of the bottom plate of the lower U-shaped bracket, and only the center pin that can move up and down is exposed, thereby ensuring the effective stroke of the center pin. At the same time, the center pin end of the spring plunger is against the upper bracket.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to further understand the features and technical contents of the present invention, the following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and implementation methods:

[0025] The utility model provides an external hard disk fixing structure for an automatic driving data recording system controller, such as Figure 1 As shown, the external hard disk 1 is fixed above the autonomous driving data recording system controller 8; data is transmitted between the hard disk and the controller via a data adapter cable 7.

[0026] The specific structure of this embodiment is as follows Figure 2 As shown, it includes a hard disk 1, double-sided tape 2, an upper U-shaped bracket 3, a fastening screw 4, a lower U-shaped bracket 5, a spring plunger 6, a data adapter cable 7, and an autonomous driving data recording system recording controller 8.

[0027] The lower U-shaped bracket is placed on top of the controller housing and fixed to the controller housing with four screws. The upper U-shaped bracket is used to fix the external hard disk. The external hard disk and the upper U-shaped bracket are bonded with double-sided tape to form a whole. Align the upper U-shaped bracket with the external hard disk into the guide slot of the lower U-shaped bracket, slide it in from top to bottom, and slide it horizontally and longitudinally so that the four bent claws of the upper U-shaped bracket match the fixed slots of the lower U-shaped bracket. Figure 5 The figure shows the state after the upper and lower U-shaped brackets are snap-fitted and fixed in place.

[0028] Figure 61 is the upper U-shaped bracket, and 10 is its claw for fixing.

[0029] Figure 7 1 is the U-shaped bracket at the bottom, and 11 is its fixing slot for fixing.

[0030] Since there is a gap between the upper and lower U-shaped brackets, in order to ensure that there is no relative sliding between the two brackets and the buckle position is loose, an elastic support is also provided at the bottom of the upper U-shaped bracket, which is realized by three spring plungers, such as Figure 4 As shown; the structure of the spring plunger is as follows Figure 8 As shown, the outer part is an external thread, and the inner part is inlaid with a coil spring. The center pin can move up and down a certain stroke and can support a certain load. The spring plunger is selected with appropriate elastic stroke and spring force to make it strong enough to support the upper U-shaped bracket so that it does not move in three directions; the elastic stroke of the spring plunger depends on the reserved gap and tolerance accumulation when the upper and lower brackets are installed, and the stroke is guaranteed to be at least ≥ gap + tolerance + 1mm; the spring force depends on the overall weight of the hard disk and the upper bracket. When the spring is compressed to the lower limit, it is necessary to ensure that the elastic force it generates is much greater than the overall weight G of the hard disk and the upper bracket, such as >50*G, to ensure that the upper bracket will not slide when the vehicle is vibrated and impacted.

[0031] Since the bottom of the lower U-shaped bracket has an opening, the spring plunger passes through the opening and is directly fixed in the threaded hole of the upper shell of the controller, limiting its screwing depth to ensure the effective stroke of the end center pin and support the upper U-shaped bracket. Alternatively, the spring plunger is first screwed into the controller housing, and then the lower U-shaped bracket is placed. At this time, the spring plunger passes through the hole of the lower U-shaped bracket, exposing the center pin, and the bottom of the lower U-shaped bracket will not interfere with the spring plunger.

[0032] The corresponding installation sequence of this embodiment is: first, adhere the external hard disk to the upper U-shaped bracket with double-sided tape; screw the spring plunger into the screw hole in the upper shell, control the screwing depth, and then place the lower U-shaped bracket above the upper shell of the controller and fix it to the upper shell with screws; finally, align the claws of the upper U-shaped bracket with the hard disk with the guide slot of the lower U-shaped bracket, press it into the guide slot from top to bottom, squeeze the center pin of the spring plunger vertically downward, and then slide the upper U-shaped bracket horizontally and longitudinally so that its claws slide to the corresponding fixed slot position of the lower U-shaped bracket, and release the upper U-shaped bracket; due to the elasticity of the coil spring inside the spring plunger, its center pin will press the upper U-shaped bracket upward so that its claws are firmly stuck in the fixed slot of the lower U-shaped bracket, thereby fixing it in place.

[0033] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above specific embodiments. The above specific embodiments and the description in the specification are only for further illustrating the principles of the utility model.
