Description

Technical Field

[0001] This utility model relates to the field of pressure sensor technology, and in particular to a modular quick-release air conditioning pressure sensor. Background Technology

[0002] The air conditioning pressure sensor is one of the most important sensors in a car's refrigeration system. Its main function is to monitor the refrigerant pressure within the air conditioning lines, preventing abnormal pressure from damaging the compressor. It also works with other components to control the operation of the cooling fan and compressor. The air conditioning pressure sensor is typically installed on the high-pressure air conditioning line in the engine compartment. The pressure signal it collects is primarily output to the engine ECU or air conditioning control unit. Upon receiving a normal signal, the ECU will issue a command to control the compressor and cooling fan to operate. If it receives an abnormal pressure signal, it will issue a command to refuse to operate the compressor and other air conditioning equipment to avoid damaging the refrigeration system.

[0003] Chinese Patent Publication No. CN 219142081 U discloses an automotive air conditioning pressure sensor, including a housing. A medium inlet pipe is fixedly connected to the lower surface of the housing, and a medium channel is formed through the bottom of the medium inlet pipe. A pressure-bearing cavity is formed inside the medium inlet pipe. A port connector is fixedly connected to the top surface of the housing. A frame is fixedly connected to the outer surface of the port connector, and a circular hole is formed through the outer surface of the port connector. A sleeve is fixedly connected to the inner wall of the frame. A push rod is slidably connected inside the sleeve, and a spring head is slidably connected to the outer surface of the sleeve. This utility model reduces the impact force when the refrigerant enters instantaneously by setting a pressure-bearing cavity, thereby protecting components such as ceramic plates. By setting a lever, when it is necessary to disassemble the wire plug, simply move the lever to drive the limiting plate. The limiting plate compresses the spring, causing the push rod to completely disengage from the circular hole of the wire plug. Thus, pulling the wire plug upwards separates the wire plug from the port connector.

[0004] The existing technical solutions mentioned above have the following shortcomings: during use, the housing and medium pipe are difficult to install and remove, and the maintenance of individual components is inconvenient, leaving room for optimization. Therefore, a modular quick-release air conditioning pressure sensor needs to be designed to solve the problems mentioned above. Utility Model Content

A circuit board is installed inside the housing, and a plug is connected to the inside of the end, with a wire connected to the top of the plug. A heat dissipation mesh is installed on the outer side of the end.

[0008] Furthermore, the medium tube has a medium channel inside, and the cross-section of the medium channel is wavy.

[0009] Furthermore, the top end of the medium tube is uniformly provided with positioning grooves, and the bottom end of the shell is uniformly fixed with positioning blocks, and the positioning blocks are all connected to the positioning grooves.

[0010] Furthermore, the size of the positioning groove is matched with the size of the positioning block, and the cross-sections of both the positioning groove and the positioning block are set to be circular.

[0011] Furthermore, six sets of positioning grooves and positioning blocks are provided, with the positioning grooves arranged in a ring at the top of the medium tube.

[0012] Furthermore, the width of the rotating block is matched with the width of the rotating groove, the cross-section of the rotating block and the rotating groove are both convex, the bottom end of the rotating block and the locking plate are provided with anti-slip texture, and the locking plate and the medium tube are connected by bolts.

[0015] Based on existing technology, a modular and detachable structure is designed between the shell and the medium pipe. During use, the connection point uses three sets of sealing blocks, sealing grooves, and sealing rings in a low, high, and low configuration to compensate for the sealing performance of the joint. At the same time, the locking plate can be rotated to the top of the connecting block after connection through the action of the rotating block and the rotating groove. With the help of bolts, a two-way locking purpose can be achieved in both directions, making it less prone to loosening. In other words, individual components can be replaced and maintained through the modular structure, improving practicality and flexibility, while ensuring the sealing and stability of the connection point.

A medium tube 12 is connected to the bottom of the housing 5.

[0025] The medium tube 12 has a medium channel 13 inside, and the cross-section of the medium channel 13 is wavy.

[0026] Specifically, such as Figure 1 As shown, during use, the cross-section of the medium channel 13 is wavy, which can reduce impact;

[0027] The top end of the medium tube 12 is uniformly provided with positioning grooves 17, and the bottom end of the housing 5 is uniformly fixed with positioning blocks 18, and the positioning blocks 18 are all connected to the positioning grooves 17. The size of the positioning grooves 17 is matched with the size of the positioning blocks 18. The cross-sections of the positioning grooves 17 and the positioning blocks 18 are all circular. There are six sets of positioning grooves 17 and positioning blocks 18. The positioning grooves 17 are arranged in a ring at the top end of the medium tube 12.

[0028] Specifically, such as Figure 2 As shown, during use, the positioning grooves 17 of multiple sets of positioning blocks 18 can achieve the purpose of positioning and connecting the housing 5.

[0029] The top end of the medium tube 12 is uniformly fixed with sealing blocks 14. There are three sets of sealing blocks 14, and the heights of the three sets of sealing blocks 14 are arranged in a low-high-low pattern. The bottom end of the housing 5 is uniformly provided with sealing grooves 15, and the sealing grooves 15 are all connected to the sealing blocks 14. The outer side of the sealing blocks 14 is uniformly provided with annular grooves 20, and the interior of the annular grooves 20 is connected with sealing rings 19. The top end of the medium tube 12 is fixed with four sets of connecting seats 11, and the interior of the connecting seats 11 is provided with rotating grooves 10. The interior of the rotating grooves 10 is rotatably connected with rotating blocks 9.

[0030] The width of the rotating block 9 is matched with the width of the rotating groove 10. The cross-sections of the rotating block 9 and the rotating groove 10 are both convex. The bottom ends of the rotating block 9 and the locking plate 8 are provided with anti-slip textures. The locking plate 8 and the medium tube 12 are connected by bolts.
