Description

Technical Field

[0001] The present invention relates to the technical field of automobile key testing, and in particular to a modular automobile key testing fixture. Background Art

[0002] With the development of intelligent automotive technology and the continuous improvement of vehicle specifications, higher requirements are being placed on automotive accessories, especially for frequently used remote control keys. As electronic products, remote control keys must undergo a series of quality inspections before leaving the factory. For example, the keys on the remote control key need to be inspected. Existing technology typically uses a cylinder to drive multiple pressure blocks to simulate pressing the keys. A magnetic switch installed on the cylinder detects the cylinder's stroke to test whether the pressure blocks can be pressed into place. If the pressure blocks are pressed into place, the key function is qualified.

[0003] However, since the cylinder usually needs to be connected to an air source and the magnetic switch needs to be connected to a test system, and the air source and the test system are not convenient to move, existing modular car key test fixtures usually fix the cylinder and the magnetic switch in a shielded box. However, this makes it inconvenient to replace the cylinder and the magnetic switch in time when they are damaged. Summary of the Invention

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is now described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic principles of the present invention in an illustrative manner, and therefore only shows the structures related to the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Please refer to Figure 1An embodiment of the present invention provides a modular automotive key test fixture 100, comprising a carrier 10 for placing automotive keys and a shielding box 20. Specifically, the carrier 10 described in this embodiment is typically connected to a conveyor line. During testing, a lifting mechanism on the conveyor line lifts the carrier 10 until the carrier 10 and the mounting slot 21 form a sealed space. The conveyor line and lifting mechanism are not shown in the figure.

[0028] Please refer to Figure 1 and Figure 2 The bottom of the shielding box 20 is provided with a mounting slot 21 for the carrier 10 to pass through, and a test connection assembly is provided inside the shielding box 20. The shielding box 20 includes a main body 22 and a top cover 23. The main body 22 is provided with a gas spring 221 and a quick clamp 222. The output end of the gas spring 221 is fixedly connected to the top cover 23. The gas spring 221 is used to support the top cover 23, and the quick clamp 222 is used to secure the top cover 23 to the main body 22. Specifically, in this embodiment, the gas springs 221 are arranged at an angle and are arranged in pairs at both ends of the shielding box 20 in the width direction.

[0029] When the situation inside the shielding box 20 needs to be observed, the quick clamp 222 is opened to separate the upper cover 23 from the main body 22 , and the upper cover 23 is supported by the gas spring 221 so that the upper cover 23 moves obliquely upward to expose the test connection assembly inside the shielding box 20 .

[0030] Please refer to Figure 1 Shielding box 20 is equipped with ferrite (not shown). Mounting slot 21 is provided with absorbing cotton 211. The ferrite on the inner wall of shielding box 20 and absorbing cotton 211 in mounting slot 21 combine to effectively suppress external electromagnetic interference and internal signal reflection, ensuring a pure test environment.

[0031] Please refer to Figure 2 、 Figure 3 and Figure 4 The test connection assembly includes a support frame 31 and a contact module. The support frame 31 is provided with a signal female connector 311 and an air pipe female connector 312. The signal female connector 311 is connected to the test system, and the air pipe female connector 312 is connected to the air source. Specifically, in this embodiment, the test system and air source are not shown in the figure. The shielding box 20 has a wall provided with a connector for connecting the test system wiring and the air pipe to the air source. The connectors are made of shielding material.

[0032] Please refer to Figure 5 and Figure 6The contact module includes a mounting frame 32 and a plurality of pressing cylinders 33 disposed on the mounting frame 32. The mounting frame 32 is detachably connected to the support frame 31. The mounting frame 32 is provided with a signal male connector 321 corresponding to the signal female connector 311, and a tracheal male connector 322 corresponding to the tracheal female connector 312. The air inlet of the pressing cylinder 33 is connected to the tracheal male connector 322 via the trachea. The output end of the pressing cylinder 33 is connected to a pressing block 331. The mounting frame 32 is provided with a magnetic switch 323 corresponding to the pressing cylinder 33. The magnetic switch 323 is connected to the signal male connector 321 and is used to detect whether the pressing block 331 is pressed into place. Specifically, in this embodiment, the mounting frame 32 is threadedly connected to a connecting block 34, which is threadedly connected to the support frame 31 via bolts.

[0033] By integrating the pressure cylinder 33 and magnetic switch 323 into a modular assembly on the mounting frame 32, the air port connector of the pressure cylinder 33 and the signal connector of the magnetic switch 323 are separated into pluggable male and female connectors. The male connector is used to connect to the air source and test system. When testing is required, the male connector is simply inserted into the corresponding female connector to connect to the air source and test system. During disassembly, the male connector is pulled out from the female connector, and then the mounting frame 32 is removed from the support frame 31 to complete the removal and replacement of the pressure cylinder 33 and magnetic switch 323.

[0034] Specifically, in this embodiment, the number of pressing cylinders 33 is adjusted according to the number of buttons on the car key, thereby adapting to car keys of different sizes and button layouts. Furthermore, since car key buttons are relatively small, the pressing cylinders 33 in this embodiment of the present invention are compact, thereby saving space.

[0035] Please refer to Figure 3 The support frame 31 is provided with a positioning column 314, and the mounting frame 32 is provided with a positioning hole 326 adapted to the positioning column 314. By matching the positioning column 314 with the positioning hole 326, it is convenient to position the mounting frame 32 when it is installed on the support frame 31.

[0036] Please refer to Figure 5 and Figure 6 The mounting frame 32 includes a first connecting plate 324 and a second connecting plate 325. The trachea male connector 322 and the signal male connector 321 are both installed on the first connecting plate 324. Multiple pressing cylinders 33 are all installed on the second connecting plate 325. The first connecting plate 324 is provided with a first connecting groove 3241. The first connecting groove 3241 is used to pass through the trachea connecting the air port of the pressing cylinder 33 and the trachea male connector 322, as well as the wiring connecting the magnetic switch 323 and the signal male connector 321. The second connecting plate 325 is connected with a mounting block 3251 for loading multiple pressing cylinders 33.

[0037] Please refer to Figure 1 and Figure 5 A handle 24 is provided on the shielding box 20 and the first connecting plate 324 to facilitate the disassembly and replacement of the pressing cylinder 33 and the magnetic switch 323, as well as the entire shielding box 20.

[0038] Please refer to Figure 5 and Figure 6 The second connecting plate 325 is provided with a second connecting slot 3252 for the pressing block 331 to pass through. Specifically, when testing the car key, the second connecting plate 325 is located below the first connecting plate 324 and is closer to the carrier 10 relative to the first connecting plate 324.

[0039] Please refer to Figure 5 and Figure 6 The second connecting plate 325 is connected to a first support column 3253, which is used to contact the vehicle 10. The second connecting plate 325 is connected to a support block 3254, which is connected to a plurality of second support columns 3255, which are used to contact the car key. Specifically, in this embodiment, the bottom end of the first support column 3253 is at a lower height than the bottom end of the second support column 3255. The ends of the first support column 3253 and the second support column 3255 are made of rubber to reduce pressure on the key and the vehicle 10.

[0040] Please refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 A fiber optic control box 313 is placed on the support frame 31. Multiple test optical fibers 3131 are connected to the fiber optic control box 313. A second connecting plate 325 is provided with through-holes 3256 for the test optical fibers 3131 to pass through. The test optical fibers 3131 are positioned toward the car key. Specifically, in this embodiment, the test optical fibers 3131 are not shown. The brightness of the test optical fibers 3131 reflects the brightness of the LED light when a key is pressed in the car key. When testing the brightness of the LED light when a key is pressed, the test optical fibers 3131 are passed through the through-holes 3256 in the second connecting plate 325, with one end of the test optical fibers 3131 facing the car key. The key is pressed by pressing the cylinder 33, and the brightness of the test optical fibers 3131 reflects the brightness of the LED light when the key is pressed. Positioning the fiber optic control box 313 on the support frame 31 also facilitates removal and replacement of the pressing cylinder 33 and the magnetic switch 323.
