Description

Technical Field

[0001] The utility model relates to the technical field of driving recorder production, in particular to a collision detection device of a driving recorder. Background Art

[0002] A dash cam is an instrument that records images, sounds and other related information while a vehicle is driving. The images and sounds recorded by the dash cam can be used as important evidence of traffic accidents. The collision sensing sensitivity of a dash cam refers to the reaction speed of the dash cam when it detects a collision between a vehicle and other objects. Specifically, it is the time it takes for the dash cam to record after sensing a collision. In order to ensure that it can record accurately and timely in traffic accidents, the dash cam has high requirements for its collision sensing sensitivity. Therefore, before the dash cam leaves the factory, it is necessary to use a dash cam collision detection device to test the collision sensing sensitivity. However, the current dash cam collision detection device still has the following deficiencies:

[0003] For example, the patent document with application number 202223207980.1 discloses a vibration detection device for the running stability of a driving recorder. The vibration detection device for the running stability of a driving recorder observes the stability of the driving recorder in a vibrating state by replacing driving discs of different sizes and connecting rods of different lengths, thereby realizing the detection of the anti-vibration performance of the driving recorder. However, it can only detect a single driving recorder, and the driving recorder is not firmly fixed during the detection process.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a collision detection device for a driving recorder is proposed. Utility Model Content

[0012] Furthermore, the collision assembly also includes an open counterweight ring and an elastic limiting pad, and the surface of the guide rod is provided with an open counterweight ring, and the opening of the open counterweight ring is bonded with an elastic limiting pad.

[0013] Furthermore, servo motors are installed on both sides of the upper surface of the support frame, and the output end of the servo motor is connected to a threaded screw through a coupling, and the surface of the threaded screw is threadedly connected to the surface of the support plate.

[0014] The utility model provides a collision detection device for a driving recorder, which has the following beneficial effects:

[0015] 1. The utility model is provided with a fixing component, which includes a collision plate, a receiving groove, a fixing box, a partition seat, a return spring and a fixing plate. When in use, the driving recorder is placed between two sets of fixing plates. The fixing plate is squeezed to drive the return spring to be contracted. Due to the elastic effect of the return spring itself, the rebound of the return spring will drive the fixing plate to generate a certain force, so that the fixing plate is close to the driving recorder, and the driving recorder is fixed and limited. The fixing box is divided into four small spaces by the partition seat, and multiple groups of driving recorders can be detected at the same time, so that the device can perform collision detection on multiple driving recorders in the same batch at the same time, and it can firmly fix the driving recorder to prevent it from falling during the detection process.

[0016] 2. The utility model provides a support plate, a servo motor, a threaded screw and a collision assembly, wherein the collision assembly includes an electric push rod, an arc-shaped limit piece and a guide rod, and the collision assembly also includes an open counterweight ring and an elastic limit pad.

The arc-shaped limit piece supports the open counterweight ring, and the servo motor is started to drive the threaded screw to rotate, and further drive the support plate to move up and down along the surface of the threaded screw. After the electric push rod moves to a suitable height, the electric push rod is started to drive the arc-shaped limit piece to move toward the outer end. After the open counterweight ring is no longer supported by the arc-shaped limit piece, it descends along the guide rod and impacts the inner side of the limit groove, causing the collision plate to shake to a certain extent, causing the driving recorder to shake. Open counterweight rings of different weights can be replaced during detection, so that the device can detect the collision sensitivity of the driving recorder when it is subjected to different impact forces by adjusting the weight of the open counterweight ring and the descending height.

[0024] The specific operation is as follows. When in use, the driving recorder is placed between two groups of fixed plates 306. The fixed plates 306 are squeezed and the return springs 305 are forced to contract. Due to the elastic effect of the return springs 305 themselves, the rebound of the return springs 305 will drive the fixed plates 306 to generate a certain force, so that the fixed plates 306 are close to the driving recorder, and the driving recorder is fixed and limited. The fixed box 303 is divided into four small spaces by the partition seat 304, and multiple groups of driving recorders can be tested at the same time.

[0025] Please refer to Figures 1 to 3 The collision plate 301 is a hard plastic structure, and an elastic rubber pad 4 is bonded to the surface of the collision plate 301 on one side away from the return spring 305. A limiting groove 5 is provided on the upper surface of the collision plate 301, and two groups of limiting grooves 5 are symmetrically arranged. Support frames 6 are installed on both sides of the upper surface of the base 1, and a supporting top plate 7 is arranged on the inner side of the upper end of the support frame 6. Servo motors 10 are installed on both sides of the upper surface of the support frame 6, and the output end of the servo motor 10 is connected to a threaded screw 11 through a coupling, and the surface of the threaded screw 11 is threadedly connected to the surface of the support plate 8;

[0026] The specific operation is as follows: when in use, the elastic rubber pad 4 can play a certain buffering role on the driving recorder to prevent scratches on its surface; the servo motor 10 is started, so that the servo motor 10 drives the threaded screw 11 to rotate, and further drives the support plate 8 to move up and down along the surface of the threaded screw 11, thereby adjusting the descent height of the open counterweight ring 904.

The arc limit piece 902 supports the open counterweight ring 904. After the electric push rod 901 moves to a suitable height, the electric push rod 901 is started to drive the arc limit piece 902 to move toward the outer end. After the open counterweight ring 904 is no longer supported by the arc limit piece 902, it descends along the guide rod 903 and hits the inner side of the limit groove 5, causing the collision plate 301 to shake to a certain extent, causing the driving recorder to shake. The open counterweight rings 904 of different weights can be replaced during detection.

[0029] In summary, if Figures 1 to 4 As shown, the collision detection device of the driving recorder is used. First, the driving recorder is placed between the two sets of fixing plates 306. The fixing plates 306 are squeezed and the return springs 305 are forced to contract. Due to the elastic effect of the return springs 305 themselves, the rebound of the return springs 305 will drive the fixing plates 306 to generate a certain force, so that the fixing plates 306 are close to the driving recorder, and the driving recorder is fixed and limited. The fixing box 303 is divided into four small spaces by the partition seat 304, and multiple sets of driving recorders can be detected at the same time. The elastic rubber pad 4 can play a certain buffering role on the driving recorder to prevent scratches on its surface.

After the electric push rod 901 moves to a suitable height, the electric push rod 901 is started to drive the arc limit piece 902 to move toward the outer end. After the open counterweight ring 904 is no longer supported by the arc limit piece 902, it descends along the guide rod 903 and hits the inner side of the limit groove 5, causing the collision plate 301 to shake to a certain extent, causing the driving recorder to shake, so as to perform inspection.
