[0025] See also Figure 1 to Figure 2The present application proposes a TOF sensor testing device, which is used to test the performance of a TOF sensor, and includes: a base fixing platform 10, a sliding assembly 20 and a probe PCB board 30.

[0026] The base fixing platform 10, on which the TOF sensor is fixed, comprises: a connecting arm 11, an extension arm 12 extending vertically from both ends of the connecting arm 11, a groove 13 and a support plate 14, wherein the connecting arm 11 and the extension arm 12 are connected to form a containing space, the support plate 14 is arranged in the middle of the inner side of the base fixing platform 10 to separate the containing space into upper and lower sides, the groove 13 surrounds the support plate 14 and is arranged on the upper side of the containing space, and the bottom surface of the groove 13 is flush with the top surface of the support plate 14. The sliding assembly 20 is slidably arranged on the upper side of the base fixing platform 10, and is used to lock the TOF sensor on the support plate 14 of the base fixing platform 10. The probe PCB board 30 is arranged on the lower side of the base fixing platform 10, and is used to connect the TOF sensor and the peripheral test circuit.

[0027] In this embodiment, the base fixing platform 10 also includes: a limiting portion 15, which is arranged at one end of the extension arm 12 away from the connecting arm 11 to limit the sliding component 20 from sliding out of the groove 13. The sliding component 20 matches the shape of the groove 13 and slides in the groove 13. When the sliding component 20 slides to the limiting portion 15, the sliding component 20 locks the TOF sensor on the support plate 14.

[0028] In this embodiment, a positioning hole is provided on the support plate 14 , and the TOF sensor is positioned on the support plate 14 by inserting a pin into the positioning hole.

[0029] In this embodiment, a first slide rail 17 is provided in the groove 13 along the direction of the extension arm 12, and the base fixing platform 10 further includes a cover plate 16, and the cover plate 16 is provided with a second slide rail 18 corresponding to the first slide rail 17. The cover plate 16 is arranged on the top surface of the base fixing platform 10 and forms a sliding space with the groove 13. The cover plate 16 is fixed to the base fixing platform 10 by screws (not shown).

[0030] In this embodiment, the sliding assembly 20 is configured to match the shape of the groove 13 of the base fixing platform 10, and includes a first connecting member 21 and a second connecting member 22 extending in a vertical direction at both ends of the first connecting member 21. An inserting portion 23 is provided at one side of the bottom of the second connecting member 22, and the inserting portion 23 is provided with a sliding guide rail 24 corresponding to the first slide rail 17 and the second slide rail 18. The inserting portion 23 extends into the sliding space so that the sliding guide rail 24 moves along the groove, driving the sliding assembly 20 to slide in the sliding space.

[0031] In this embodiment, the sliding assembly 20 further includes an elastic member 25 and a locking member 26 . The locking member 26 is disposed on the first connecting member 21 of the sliding assembly 20 . The first connecting member 21 of the sliding assembly 20 abuts against the inner side of the connecting arm 11 through the elastic member 25 .

[0032] The locking member 26 includes a pin 261 and a handle ring 262 connected to the pin 261. An insertion hole is provided at a position of the groove 13 near the connecting arm 11. One end of the pin 261 passes through the first connecting member 21 and is inserted into the insertion hole, and the other end of the pin 261 is connected to the handle ring 262. When the TOF sensor needs to be locked and fixed, the handle ring 262 is lifted to disengage the pin 261 from the insertion hole. The sliding assembly 20 slides to the limit portion 15 along the first slide rail 17 under the pushing action of the elastic member 25. When the TOF sensor needs to be released, the sliding assembly 20 is pushed to a position close to the connecting arm 11, and the sliding assembly 20 is locked by inserting the pin 261 into the insertion hole.

[0033] The elastic member 25 is a spring. The first connecting member 21 and the connecting arm 11 of the base fixing platform 10 are both provided with fixing holes (not shown) corresponding to the spring, and both ends of the spring extend into the fixing holes.

[0034] The cover plate 16 is configured to match the shape of the base fixing platform 10 , and is fixed to the top of the base fixing platform 10 by screws (not shown).

[0035] The probe PCB board 30 is fixed to the lower side of the base fixing platform 10 by screws. In this embodiment, the probe PCB board 30 includes a PCB board and a PIN pin. Because the probe PCB board has been wired and the probes have been soldered, and there is a cable tray on it, the probe PCB board 30 is fixed to the base fixing platform 10 with four screws, and the probe and the PCB board on the TOF sensor are in elastic contact.

[0036] The bottom of the base fixing platform 10 is also provided with a foot pad 40. In this embodiment, the base of the base fixing platform 10 is affixed with an anti-skid foot pad.

[0037] Combine the following Figures 1 to 5 The working principle of this application is explained.

[0038] After the test device is assembled, slide the sliding assembly 20 close to the connecting arm 11, press the handle ring 262 to insert the pin 261 into the insertion hole, and then install the TOF sensor on the support plate 14 and connect it to the probe PCB board 30.

[0039] After installing the TOF sensor, pull the bracelet 262 upwards, the pin 261 withdraws from the insertion hole, and the elastic force of the spring 25 pushes the sliding assembly 20. The sliding assembly 20 moves through the first slide rail 17 and the second slide rail 18, gradually changing from loose to tight. The sliding assembly 20 and the probe PCB board 30 press the TOF sensor.

[0040] After the TOF sensor is assembled, functions such as burning, testing, calibration and ranging can be performed through the probe of the probe PCB board 30.

[0041] Because the sliding component 20 has two upper and lower slide grooves and a limit portion, it can slide without too much force and will not slide too far, which is convenient and labor-saving. The probe on the probe PCB board 30 can be connected to the outside through a cable for testing, thus forming a small, convenient and easy-to-use module test bench. This TOF sensor multifunctional test bench utilizes the characteristics of a small module, combines the probe and the sliding component, and can perform functions such as module burning, calibration, testing and ranging without welding. The installation is simple and convenient, reducing the risk of damage caused by repeated welding, saving a lot of valuable time and cost for mass production.

[0042] The technical solution of this application has the following technical effects:

[0043] 1. This solution uses a simple test bench device to complete a series of burning, calibration, ranging and other functions. There is no need for welding wires, the installation is simple and convenient, and the cost is lower. The equipment is simple. If one probe is broken, it can be taken down and replaced. The assembly and disassembly are very convenient.

[0044] 2. The utility model effectively improves the problems of high cost, complicated operation and low efficiency of traditional test fixtures, is flexible in assembly, and improves the usability of the product.

[0045] 3. This structural design can be applied to many products and can fully meet the needs of R&D and production. It has a simple structure and is easy to install. It can effectively reduce the labor costs of mold opening and assembly, and greatly improve production efficiency.
