Fig. 1 shows a schematic structural view of a fixing device according to an embodiment of the present invention. Fig. 2 shows a state diagram of the use of the fixing device according to an embodiment of the utility model. As shown, an EDR bench test fixture 100 mainly includes a base 101, a fixing column 102, a first screw 103, and a second screw 104.

The base 101 has a long plate shape. A long mounting groove 105 is opened in the longitudinal direction of the base 101. The base 101 is disposed on the test stand 200.

The fixing column 102 is provided on the base 101. The fixing column 102 is provided with an assembly hole which is vertically through.

The first screw 103 passes through a mounting hole of the EDR 300 and a mounting hole on the fixing column 102 and is matched and fixed with a threaded mounting hole 202 on the test stand 200. The fixing post 102 is fixed between the test stand 200 and the EDR 300. A second screw 104 extends through mounting slot 105 and engages threaded mounting hole 202 in test rig 200 to secure base 101 to test rig 200.

It will be readily appreciated that the EDR 300 may be fixed on top of the fixing post 102 of the fixing device 100 by generally three or four fixing devices 100 provided by the present invention, so that the EDR 300 is fixed to the test stand 200 by the fixing device 100.

Preferably, the fixing post 102 is disposed at one end of the base 101 in the length direction. The length direction of the fixing column 102 is perpendicular to the length direction of the base 101, and the fixing column 102 and the base 101 form an L-shaped component. The EDR 300 may be fixed by a plurality of L-shaped members. By adjusting the position of the L-shaped member on the test bed 200 so that the mounting holes of the fixing posts 102 are aligned with the threaded mounting holes 202 on the test bed 200, the distance between the fixing posts 102 of different L-shaped members can be adjusted to be suitable for the fixed mounting of different models of EDRs 300.

Preferably, the fixing post 102 is cylindrical. The position of the base 101 on the test stand 200 can be adjusted by rotating the base 101 about the axis of the fixed column 102. Corresponding to the rotating fixing device 100, the operator holds the fixing post 102 with one hand and rotates the base 101 with the other hand, so that the adjustment operation is convenient.

Preferably, the width of mounting slot 105 is greater than the diameter of threaded mounting hole 202 on test stand 200. During assembly, the base 101 is rotated so that the mounting slot 105 covers the threaded mounting hole 202, and the second screw 104 is screwed into the threaded mounting hole 202 to fix the base 101. It will be readily appreciated that if mounting slot 105 covers multiple threaded mounting holes 202, multiple second screws 104 may be used to secure base 101 to different threaded mounting holes 202, respectively, if desired.

Preferably, an impact matrix table 201 is provided on the test rig 200. A plurality of threaded mounting holes 202 are provided in the top surface of the impact matrix table 201. The fixture 100 is secured to the test rig 200 by an impact matrix table 201.

Preferably, the fixing post 102 has a set length. Fixing devices 100 with fixing columns 102 of different lengths are selected for fixing the EDRs 300 of different models and sizes. The distance between the EDR 300 and the top surface of the shock matrix table 201 can be adjusted, and the installation angle of the EDR 300 can be adjusted by the position of the fixing device 100, so that the connector can be conveniently connected to the EDR 300 to form a data path.

Preferably, the ratio of the length of the fixing post 102 to the length of the base 101 is 1:3 to 1: 2.

Preferably, the fixing device 100 is made of a metal material.

The EDR bench test fixing device designed by the utility model has the following advantages:

1. different numbers of fixing devices can be selected according to EDRs of different models and sizes for connection and fixation, so that the compatibility is high;

2. the mounting hole of the EDR is utilized, the mounting mode of the EDR on the vehicle body can be reproduced, and the EDR has higher strength and is efficient and convenient to mount;

3. the EDR can be lifted through the fixing column, so that the influence of different fixing modes of the EDR on the installation is avoided;

4. the mounting position and angle of the fixing device on the test bed can be adjusted arbitrarily according to the size of the EDR and the connection mode of the connector, so that the mounting area of the test bed is fully utilized;

it will be apparent to those skilled in the art that various modifications and variations can be made to the above-described exemplary embodiments of the present invention without departing from the spirit and scope of the utility model. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
