Description

Technical Field

[0032] In this invention, the terms "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0033] like Figure 1As shown, a test device for sensor testing according to an embodiment of the present invention includes a cabinet 1, a spraying device 2, and a clamping device 3. The spraying device 2 is disposed inside the cabinet 1 and includes a first driving component and a spraying structure. The output end of the first driving component is connected to one end of the spraying structure, and the input end of the first driving component is connected to the other end of the spraying structure. The first driving component is used to drive liquid to circulate sequentially through the output end of the first driving component, the first driving component, and the input end of the first driving component. The clamping device 3 is disposed inside the cabinet 1 and is used to clamp the sensor. The spraying structure is used to spray liquid toward the sensor.

[0034] The aforementioned testing equipment for sensor testing incorporates a clamping device 3 to hold and fix the sensor, preventing displacement caused by impact from the sprayed liquid during testing and thus affecting the test results. It also includes a spraying device 2 to test the sensor's waterproof performance. This testing equipment solves the problem that traditional waterproof testing devices cannot test sensors with different waterproof requirements.

[0035] In one embodiment, such as Figure 3As shown, the injection structure includes a rotating assembly 21 and a second driving assembly 22. The second driving assembly 22 drives the rotating assembly 21 to rotate, and its output end is connected to the driving assembly. The rotating assembly 21 includes a first connecting pipe 211 and two rotating members 212. The outer contour of the first connecting pipe 211 is arc-shaped. One rotating member 212 is connected to one end of the first connecting pipe 211, and the other rotating member 212 is connected to the other end of the first connecting pipe 211. The output end of the first driving assembly is connected to one of the rotating members 212, and the input end of the first driving assembly is connected to the other rotating member 212. The rotating member 212 includes a second connecting pipe 2121 and a first bearing 2122. One end of the second connecting pipe 2121 is connected to the output end of the first driving assembly. The first connecting tube 211 is connected to the second connecting tube 2121 at one end, and the other end of the second connecting tube 2121 is stepped. The first bearing 2122 is inserted into the stepped end of the second connecting tube 2121, and the outer ring of the first bearing 2122 is connected to the second connecting tube 2121. One end of the first connecting tube 211 is inserted into the inner ring of the first bearing 2122 and connected to the inner ring of the first bearing 2122. The second driving assembly 22 includes a first gear 221 and a first driving block 222 for driving the first gear 221 to rotate. The first driving block 222 is disposed on the outer surface of the second connecting tube 2121, and the output end of the first driving block 222 is connected to the first gear 221. A first rack 12 is sleeved on the end of the first connecting tube 211 inserted into the first bearing 2122, and the first gear 221 meshes with the first rack 12. In this way, by driving the first connecting tube 211 to rotate through the second driving assembly 22, liquid can be sprayed onto the sensor from multiple angles, increasing the test coverage area and improving the test accuracy.

[0036] In one embodiment, such as Figures 2 to 5As shown, the second connecting pipe 2121 is provided with a plurality of spraying assemblies 4 communicating with the second connecting pipe 2121; the spraying assembly 4 includes a third connecting pipe 41 and a spraying element 42; one end of the third connecting pipe 41 is connected to the first connecting pipe 211, and the spraying element 42 is inserted into the other end of the third connecting pipe 41; the end of the spraying element 42 inserted into the third connecting pipe 41 is provided with a plugging block 5, the inner surface of the third connecting pipe 41 is provided with a slide 6, the plugging block 5 is inserted into the slide 6 and slidably connected with the slide 6; the third connecting pipe 41 is provided with a second driving block, A second gear is provided on the output end of the second drive block. The second drive block drives the second gear to rotate, and the second gear meshes with the spray element 42. The spray element 42 includes a second bearing 421, a sleeve 422, and a spray head 423 with a trumpet-shaped outer contour. The spray head 423 is inserted into the third connecting pipe 41. The second bearing 421 is sleeved on the outer surface of the spray head 423, and the sleeve 422 is sleeved on the outer ring of the second bearing 421. A second rack 13 and a fan blade 424 are sleeved on the outer surface of the sleeve 422, and the second gear meshes with the second rack 13. In this way, the liquid is driven through the third connecting pipe 41 by the first drive assembly and impacts the spray element 42, achieving atomization. The second drive block drives the fan blade 424 to rotate, forming a low-pressure zone at the spray head 423, improving the atomization effect.

[0037] In one embodiment, such as Figure 5 As shown, the spray element 42 is used for pressurization. By changing the spray head 423, the spray pressure of the liquid can be increased, enabling the testing of sensors with different waterproof requirements.

[0038] In one embodiment, such as Figure 6As shown, the third connecting pipe 41 is provided with a first through hole 10, and a third driving assembly 7 is provided in the first through hole 10; the spray head 423 is provided with a second through hole 11, and a fourth driving assembly 8 is provided in the second through hole 11; the fourth driving assembly 8 includes a second elastic element 81, a slide rod 82, a sliding block 83, a limiting block 84, and a second magnetic block 85. The sliding block 83 is provided with a channel. One end of the slide rod 82 is connected to the spray head 423, and the other end of the slide rod 82 extends into the channel and is slidably connected to the sliding block 83; the second elastic element 81 is sleeved on the slide rod 82, and the second elastic element 81 abuts against the spray head 423 and the sliding block 83 respectively; the slide rod 82 is located at one end in the channel. A limiting block 84 is provided, which abuts against the sliding block; a second magnetic block 85 is provided on the sliding block 83; a limiting part 9 is provided on the third connecting tube 41, and the limiting part 9 and the first elastic member 71 are disposed in the first through hole 10, which communicates with the second through hole 11; the third driving assembly 7 includes a first elastic member 71, a first magnetic block 72, and a button 73; one end of the first elastic member 71 is connected to the limiting part 9, and the other end of the first elastic member 71 is connected to one end of the first magnetic block 72, and the other end of the first magnetic block 72 is connected to the button 73, which extends outside the third connecting tube 41; the first magnetic block 72 and the second magnetic block 85 are mutually exclusive. Thus, by pressing the button 73, the first magnetic block 72 pushes the second magnetic block 85 away from the first through hole 10, thereby separating the spray head 423 from the third connecting tube 41, making it easy to disassemble and replace different spray heads 423.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
