[0002] The main function of the vehicle-mounted air pump pressure controller is to automatically monitor and control the air pressure during the inflation process. Once the preset pressure value is reached, the automatic controller will automatically stop the air pump, thereby avoiding overinflation and protecting the inflated object from damage.

[0003] However, when the battery of the tire pressure monitoring module of the pressure controller is exhausted, it cannot normally supply power to the controller display screen, and the display screen cannot display the pressure reading. In addition, the controller is generally installed inside the air pump. When inspecting the module, the entire controller casing must be removed, which has low inspection efficiency and is not convenient for quickly checking and inspecting the inside of the controller.

[0004] Therefore, a kind of air pump pressure controller that is easy to repair is needed. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a vehicle-mounted air pump pressure controller, which uses a tool to rotate the insertion rod to separate it from the pad, and then the shell cover drives the card block to slide out of the pad, so that the interior of the controller shell can be inspected, reducing the tedious steps of disassembling the entire controller for inspection.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0028] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments. Example 1

[0029] In order to make the pressure controller easy to repair, a vehicle-mounted air pump pressure controller is designed. The specific solution is as follows:

[0030] like Figure 1-7 As shown, a vehicle-mounted air pump pressure controller includes a controller housing 1, and several connecting blocks 2 are fixed to the side walls of the controller housing 1. A sealing mechanism 3 is installed on the controller housing 1, and the sealing mechanism 3 includes a shell cover 301 and an insertion rod 302. The shell cover 301 is clamped and installed on the controller housing 1, and the insertion rod 302 is rotatably connected to the shell cover 301. Several clamping blocks 306 are fixedly installed on the shell cover 301, and several pads 304 are fixedly installed in the controller housing 1. A clamping groove 305 is provided in the pad 304, and a clamping block 306 is clamped and installed in the clamping groove 305. The end of the insertion rod 302 is threadedly connected to the pad 304, and several jacks 303 are provided on the shell cover 301. A positioning mechanism 5 is installed on the pad 304, and a connecting mechanism 4 is provided on the positioning mechanism 5.

[0031] The diameter of the controller housing 1 is larger than the diameter of the housing cover 301 , and a plurality of connecting blocks 2 are arranged in a ring shape at equal intervals. The arrangement of the connecting blocks 2 facilitates fixing the controller housing 1 inside the air pump.

[0032] The insertion rod 302 passes through the inner wall of the shell cover 301 and the block 306 , and the insertion rod 302 and the block 306 are rotatably connected. The insertion rod 302 passes through the shell cover 301 and the block 306 and can be threadedly installed at the end into the inner part of the cushion block 304 .

[0033] The insertion rod 302 is rotatably installed at the insertion hole 303 , and the clamping block 306 is engaged with the cushion block 304 . When the insertion rod 302 and the cushion block 304 are fixed together, the clamping block 306 can be limited in the cushion block 304 .

[0034] The positioning mechanism 5 includes a chip 501 and a limiting hole 502. The chip 501 is snap-fitted and installed on the controller housing 1. Several limiting holes 502 are provided on the chip 501. A limiting rod 504 is fixedly connected to the pad 304. The limiting rod 504 is snap-fitted and connected to the chip 501. A fixed block 503 is fixedly connected to the chip 501. The position of the chip 501 can be limited by the limiting rod 504.

[0035] The limiting rod 504 is located at one end of the pad 304 away from the card slot 305. The limiting rod 504 passes through the inner wall of the chip 501. The limiting rod 504 and the chip 501 are limited to prevent the chip 501 from moving during use.

[0036] The diameter of the limiting rod 504 is equal to the diameter of the limiting hole 502, and several limiting rods 504 and limiting holes 502 are arranged in a ring at equal intervals. Aligning the limiting holes 502 on the chip 501 with the limiting rods 504 can make the chip 501 engage with the limiting rods 504.

[0037] The pad 304 contacts the chip 501 , and the sidewall of the pad 304 is arranged in an arcuate structure. The arrangement of the pad 304 facilitates supporting the chip 501 .

[0038] The connecting mechanism 4 includes a pressure sensor 401 and a connecting wire 402. The connecting wire 402 is fixed on the chip 501, and the pressure sensor 401 is fixedly installed on the connecting wire 402. A card plate 404 is clamped and installed on the fixed block 503, and the card plate 404 is connected to the wire 403. The setting of the pressure sensor 401 can facilitate monitoring and control of the tire pressure during inflation.

[0039] The connecting wire 402 is located on the side wall of the chip 501 away from the pad 304 , and the card board 404 is located between the two fixing blocks 503 . The setting of the fixing blocks 503 facilitates the positioning of the card board 404 .

[0040] Instructions for use:

[0041] First, when installing the controller housing 1, the controller housing 1 can be snap-fitted and installed on the air pump housing. Since the side wall of the controller housing 1 is annular and equidistantly fixed with a number of connecting blocks 2, the connecting blocks 2 can be fixed together with the air pump housing by fixing bolts, and then the controller housing 1 can be fixed inside the air pump; the controller housing 1 is annular and equidistantly fixed with a number of pads 304, and the pads 304 are fixedly installed with a limiting rod 504, which is set on the limiting hole 500 provided on the chip 501. 2 is aligned with the limiting rod 504, so that the chip 501 is conveniently mounted on the side wall of the limiting rod 504, and the chip 501 is supported by the pad 304, so that the card plate 404 is conveniently mounted on the fixing block 503 provided on the chip 501. The card plate 404 is equipped with a wire 403, so that the operator can connect the wire 403 to the device. The chip 501 is provided with a connecting wire 402, and the end of the connecting wire 402 is equipped with a pressure sensor 401. The control system provided in the air pump can adjust the pressure according to the pressure. The pressure signal provided by the force sensor 401 is used to monitor the operating status of the air pump, and to perform automatic control and adjustment, thereby ensuring that the tire pressure is kept within a safe range and avoiding safety hazards caused by excessively high or low tire pressure. When using the controller, if there is a problem with the display screen, the operator can use a tool to rotate the insertion rod 302 installed on the shell cover 301. Since the end of the insertion rod 302 is provided with a rotating groove in a regular hexagonal structure, it is convenient to disassemble and assemble the insertion rod 302. The insertion rod 302 is away from the shell cover 301. The end thread is installed inside the pad 304, and the pad 304 is fixed in the controller housing 1. When the rod 302 is separated from the pad 304, the block 306 fixed on the shell cover 301 can lose the limit of the rod 302. Taking the shell cover 301 can drive the block 306 to slide out from the slot 305 provided on the pad 304, and then the block 306 is separated from the pad 304, so that the interior of the controller housing 1 is in an open state, and it is also convenient to inspect and repair the display screen installed on the shell cover 301.
