[0027] like Figure 1-2 As shown, an embodiment of this utility model provides an airtightness testing device for an automotive controller, including a base frame 10, a fixture 20 disposed on the top of the base frame 10, and an airtightness leak detector 30 disposed on one side of the fixture 20. The top surface of the fixture 20 has a placement groove 21 for placing and adsorbing the controller. The placement groove 21 has two adsorption areas 22 arranged side-by-side along the length of the fixture 20. Each adsorption area 22 has a suction groove 23. The bottom of the fixture 20 has an extraction hole 24 communicating with the suction groove 23. The extraction hole 24 is connected to a vacuum pump 40 inside the base frame 10 via an air pipe. The position of the extraction hole 24 can be set according to the specific conditions of the suction groove 23 and the base frame 10. It should be understood that the airtightness leak detector 30 is a conventional device in the art, and since this utility model does not make any improvements to it, its specific structure and operation will not be described in detail here.

[0028] In this embodiment of the invention, the car controller is placed in the placement slot 21 of the fixture 20 during use. Then, the vacuum pump 40 is started, and air is drawn out from the suction slot 23 through the air extraction hole 24 to generate negative pressure. Under the action of negative pressure, the controller in the suction slot 23 is firmly adsorbed into the placement slot 21, thereby tightly adsorbing the controller onto the fixture 20, realizing the rapid fixation of the controller without damaging the surface of the controller. Subsequently, the air tightness tester 30 detects its air tightness, effectively improving the detection efficiency.

[0029] Specifically, in this embodiment of the present invention, the shape of the plate placement groove 21 can be rectangular or other shapes, and this disclosure does not intend to limit it.

[0030] Specifically, in this embodiment of the invention, the size of the plate slot 21 is slightly larger than the size of the car controller, so as to limit the car controller to a certain extent.

[0031] Specifically, in this embodiment of the present invention, the height of the fixture 20 at the edge of the plate placement groove 21, i.e. the depth of the plate placement groove 21, can be set according to the thickness of the car controller, for example, it can be 0.5-0.75 times the thickness of the car controller, and this position can, to a certain extent, limit the position of the car controller, which can prevent the car controller from undergoing significant positional shift when the vacuum pump 40 is insufficient.

[0032] Specifically, such as Figure 2 As shown in this embodiment of the present invention, the suction groove 23 includes at least two first suction portions 231 extending along the length direction of the fixture 20 and at least one second suction portion 232 connected between two adjacent first suction portions 231. The second suction portion 232 communicates with the first suction portion 231. By providing suction portions extending in two directions, the suction area of ​​the suction groove 23 for the vehicle controller can be increased, which can improve the suction effect on various parts of the vehicle controller while ensuring the adsorption pressure, thereby improving the reliability of the vehicle controller.

[0033] Specifically, such as Figure 2 As shown in this embodiment of the present invention, the bottom of the plate-laying groove 21 is provided with a plurality of mounting holes 25, which are correspondingly provided with the suction groove 23, so as to fix the fixture 20 to the base frame 10 by connecting bolts. In order to improve the stability of the fixation, the plurality of mounting holes 25 can be evenly distributed on the bottom of the plate-laying groove 21. It is necessary to ensure that there is a certain distance between the mounting holes 25 and the suction groove 23 to prevent air leakage during operation, which would affect the stability of fixing the car controller.

[0034] Specifically, such as Figure 3As shown in the present invention embodiment, the base frame 10 includes a base 11 and a base plate 12. The base 11 is rotatably connected to the base plate 12. The base plate 12 can be composed of multiple plates spliced ​​together or integrally formed. It has an opening at its upper end, which is closed by rotating the base 11. The rotatable connection can be a conventional rotating mechanism that enables two components to rotate around an axis, such as a hinge or hinge, and therefore no limitation is made in the description of this embodiment.

[0035] Specifically, such as Figure 3-4 As shown in this embodiment of the present invention, the base frame 10 further includes a fixing member 50 for fixing the base 11 and the base plate 12 together. The fixing member 50 includes a locking tongue 51 symmetrically arranged on both sides of the base 11 and a locking buckle 52 symmetrically arranged on both sides of the base plate 12. The locking buckle 52 is operablely engaged with the locking tongue 51 to achieve a fixed connection between the base 11 and the base plate 12. The design of the locking tongue 51 and the locking buckle 52 increases the stability between the base 11 and the base plate 12 and reduces vibration and movement during the testing process.

[0036] Specifically, such as Figure 4 As shown in this embodiment of the utility model, handle slots 121 are provided on both sides of the base plate 12 to improve the portability and ease of use of the vehicle controller airtightness detection device.

[0037] Specifically, such as Figure 3-4 As shown in this embodiment of the utility model, the bottom of the base plate 12 is provided with foot pads 60, which are respectively located at the four bottom corners of the base plate 12 to give it better stability and provide a good detection state.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
