[0001] This utility model relates to the field of sensor testing technology, and in particular to a sensor power-on detection fixture. Background Technology

[0002] Many parts of a car require sensors to detect changes in the external environment, such as temperature and acceleration. As a product that detects changes in acceleration caused by external impacts or bumps, the collision sensor needs to accurately detect and transmit the corresponding data so that the car controller can take appropriate action. It is an important part of ensuring safe driving.

[0003] During the production of collision sensors, it is necessary to power on the sensors to test whether their internal configuration is correct and whether their data transmission function is normal. Therefore, a simple-to-operate sensor power-on testing fixture capable of batch testing is needed to facilitate the testing of collision sensors. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems in the existing technology and provide a sensor power-on detection fixture.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A sensor power-on detection fixture includes a test box.

[0007] The test box has an openable mounting plate on top, and N sensor fixing plates are installed on the top of the mounting plate. The sensor fixing plates are provided with sensor slots for the insertion of collision sensors.

[0008] A barcode reader mounting bracket is installed at the rear of the test box, and a barcode reader is installed on the barcode reader mounting bracket. All N sensor slots are located within the reading area of ​​the barcode reader.

[0009] The test box contains an insulating plate and a test circuit board. The insulating plate has N sets of pins for contacting the terminals at the bottom of the collision sensor. The circuit board is electrically connected to the pins via wires.

[0010] The mounting plate is hinged to a test pressure plate via a hinge bracket. A cylindrical handle is installed at the front end of the test pressure plate. N pressure block assemblies for pressing down on the collision sensor are installed on the test pressure plate.

[0011] The test pressure plate has a mounting block perpendicular to its bottom end installed at the front. An "L"-shaped hook plate is hinged to the mounting block. A strip plate is installed at the front of the mounting plate. A cylindrical handle is installed at the front of the hook plate. The bottom of the hook plate hooks the strip plate.

[0012] The mounting plate has a self-reset button switch installed in the middle to control the circuit board to start sensor power-on detection. The circuit board is electrically connected to the self-reset button switch by wires. A trigger rod perpendicular to the bottom of the test pressure plate is installed in the middle. When the test pressure plate is in the pressed state, the bottom of the trigger rod presses the self-reset button switch.

[0013] The pressure block assembly includes a cylindrical pressure block, a half-threaded bolt, a guide sleeve, and a compression spring. The guide sleeve is installed in a circular hole in the test lower pressure plate. The tail of the half-threaded bolt is inserted into the guide sleeve from top to bottom and is screwed to the pressure block.

Detailed Implementation

[0042] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] like Figures 1 to 22As shown, a sensor power-on detection fixture includes a test box 1. The top of the test box 1 is provided with an openable mounting plate 2. The rear end of the mounting plate 2 is hinged to the rear end of the test box 1 by a hinge 21. A cylindrical handle 3 18 is installed on the front side of one side of the mounting plate 2, and the mounting plate 2 is flipped by operating the handle 3 18.

[0044] Four sensor mounting plates 3 are mounted on the top of the mounting plate 2. The four sensor mounting plates 3 are arranged in a rectangular array. The sensor mounting plates 3 are provided with sensor slots 301 for the collision sensor 100 to be inserted. The number of sensor mounting plates 3 can be adjusted according to actual needs, and can be 2-5, preferably 4.

[0045] The shape and size of the sensor slot 301 are customized according to the shape of each model of collision sensor so that the sensor slot 301 is compatible with the shape of the collision sensor 100.

[0046] A reader mounting bracket 4 is installed at the rear of the test box 1. A reader 5 is installed on the reader mounting bracket 4. All four sensor slots 301 are located within the reading area of ​​the reader 5. The reader 5 communicates with the MES system of the production plant through a communication cable and uploads the product code information read from the top of the collision sensor to the MES system.

[0047] The test box 1 contains an insulating plate 6 and a test circuit board. The insulating plate 6 has four sets of pins 7 for contacting the wiring terminals at the bottom of the collision sensor. The circuit board is electrically connected to the pins 7 via wires. The circuit board is connected to the MES system of the production plant via a communication cable to upload the test results to the MES system.

[0048] A test pressure plate 9 is hinged to the mounting plate 2 via a hinge bracket 8.

The test pressure plate 9 is connected to the connecting plate with screws.

[0049] The test pressure plate 9 is made of transparent acrylic sheet to facilitate observation of the status of the collision sensor 100.

[0050] A cylindrical handle 10 is installed at the front end of the test pressure plate 9. The test pressure plate 9 is flipped by operating the handle 10.

[0051] Four pressure block assemblies 11 for pressing down on the collision sensor 100 are installed on the test pressure plate 9. Each pressure block assembly 11 includes a cylindrical pressure block 1101, a half-threaded bolt 1102, a guide sleeve 1103, and a compression spring 1104.

[0053] A self-reset button switch 16 is installed in the middle of the mounting plate 2 to control the circuit board to start the sensor power-on detection. The circuit board is electrically connected to the self-reset button switch 16 by wires. A trigger rod 17 is installed in the middle of the test pressure plate 9, perpendicular to the bottom of the test pressure plate 9. When the test pressure plate 9 is in the pressed state, the bottom of the trigger rod 17 presses the self-reset button switch 16.

[0054] The front of the test box 1 is equipped with a self-locking push button switch 19 that controls the circuit board switch and a self-resetting push button switch 20 that controls the code reader 5. The circuit board is electrically connected to the self-locking push button switch 19 and the self-resetting push button switch 20 by wires.

[0055] During the testing process, the collision sensor is inserted into the sensor slot, and the wiring terminals at the bottom of the collision sensor contact the pins. Press the self-locking button switch to power on the fixture. Press the self-reset button switch two to make the code reader read the product code on the top of the collision sensor and upload it to the MES system. Flip the test pressure plate downwards to hook the bottom of the hook plate and hook the strip plate. At this time, the trigger rod presses the self-reset button switch one. The circuit board tests the collision sensor and uploads the test results to the MES system, thus completing the power-on test of the collision sensor.
