[0046] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0047] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0048] Embodiment 1:

[0049] See also Figure 1-Figure 3 A wind pressure sensor with adjustable spring position includes a first shell 100 and a second shell 200 connected to the first shell 100. The first shell 100 and the second shell 200 can be connected together by threaded connection, mutual snap connection or ultrasonic welding, wherein the first shell 100 can be an air cover, and the second shell 200 can be a plastic shell. After the air cover and the plastic shell are connected, an installation cavity is formed between the two, and a diaphragm assembly 300 and a coil assembly 400 are arranged in the installation cavity. The diaphragm assembly 300 is used to produce a position change under the action of a pressure difference, thereby changing the induced inductance of the coil assembly 400, and then obtaining the wind pressure condition through the change of the induced inductance.

[0050] An installation groove 210 is arranged outside the second shell 200 , for example, the outer end surface of the second shell 200 is upwardly enclosed to form the installation groove 210 , a sealing ring 500 and a spring 600 are arranged in sequence in the installation groove 210 , and an adjusting nut 700 is arranged at the opening of the installation groove 210 .

[0051] On the one hand, the sealing ring 500 is used to cooperate with the adjusting nut 700 to play a sealing and protective role. On the other hand, the sealing ring 500 can also support the edge of the spring piece 600 and have a certain limiting installation effect on the spring piece 600. In addition, when the adjusting nut 700 is rotated, the sealing ring 500 can press on the spring piece 600, and then compress the sealing ring 500 through the spring piece 600. That is, by adjusting the compression amount of the sealing ring 500 through the adjusting nut 700, the pre-compression amount of the spring piece 600 relative to the diaphragm assembly 300 can be changed, thereby achieving the purpose of adjusting the pressure, and has the advantage of easy adjustment.

[0052] The diaphragm assembly 300 includes a wind pressure diaphragm 310, a piston plate 320 and a magnetic core 330. The periphery of the wind pressure diaphragm 310 is connected to the inner wall of the first shell 100, and the wind pressure diaphragm 310 is limited and installed through the first shell 100. The piston plate 320 is connected to the wind pressure diaphragm 310. A guide column 340 is arranged in the middle of the piston plate 320. The magnetic core 330 is sleeved on the guide column 340, and the guide column 340 is used to limit and install the magnetic core 330. At the same time, it is also convenient for the piston plate 320 to drive the magnetic core 330 to move when the wind pressure diaphragm 310 is subjected to the pressure difference. The end of the guide column 340 passes through the coil assembly 400 and the second shell 200 in turn and then abuts against the spring piece 600.

[0053] It can be understood that the guide column 340 is arranged on the piston plate 320, and the end portion of the guide column 340 facing the coil assembly 400 passes through the coil assembly 400 and the second shell 200 in sequence and then presents a butt relationship with the spring piece 600. Therefore, the guide column 340 can support the diaphragm assembly 300, prevent the diaphragm assembly 300 from sagging and eccentricity, and improve the stability of the product.

[0054] In the specific application process, the wind pressure diaphragm 310 divides the installation cavity formed between the first shell 100 and the second shell 200 into a positive pressure cavity and a negative pressure cavity, and the first shell 100 and the second shell 200 are respectively provided with a positive pressure port and a negative pressure port for connecting with the outside world. Under the pressure difference between the positive pressure cavity and the negative pressure cavity, the wind pressure diaphragm 310 is deformed, and the deformation acts on the piston plate 320, and then the piston plate 320 drives the guide column 340 and the magnetic core 330 to move, and exerts a certain squeezing effect on the spring 600, thereby changing the induced inductance of the coil assembly 400, and the wind pressure is obtained by the change of the induced inductance. When the pressure difference between the positive pressure cavity and the negative pressure cavity becomes smaller and is less than the elastic force of the spring 600, the wind pressure diaphragm 310, the piston plate 320 and the magnetic core 330 return to the initial position under the action of the spring 600.

[0055] It can be understood that when the pressure difference between the positive pressure chamber and the negative pressure chamber is greater than the elastic force of the spring 600, the deformation force generated by the wind pressure diaphragm 310 can prompt the guide column 340 to exert an extrusion effect on the spring 600, thereby causing the spring 600 to deform; when the pressure difference between the positive pressure chamber and the negative pressure chamber becomes smaller and is less than the elastic force of the spring 600, the spring 600 returns to its initial state, and then transmits the elastic force to the wind pressure diaphragm 310 through the guide column 340, causing the wind pressure module to return to its initial position.

[0056] When it is necessary to adjust the pre-compression amount of the spring piece 600 relative to the diaphragm assembly 300, it is only necessary to rotate the adjusting nut 700 relative to the position in the mounting groove 210. By changing the compression amount of the sealing ring 500 compressed by the adjusting nut 700, the pre-compression amount of the spring piece 600 relative to the diaphragm assembly 300 can be changed. Compared with the method in the background technology in which the spring piece is installed inside and the sealing assembly needs to be disassembled to adjust the adjusting shaft core, the present application has the advantage of easy adjustment.

[0057] In the present application, the spring piece 600 is installed in the installation groove 210 outside the second shell 200, that is, the spring piece 600 is installed in a post-installation manner, which has the advantages of convenient installation and replacement compared with the original internal installation method; by rotating the adjusting nut 700, the adjusting nut 700 is pressed on the spring piece 600, and then the sealing ring 500 is compressed, that is, by adjusting the compression amount of the sealing ring 500 by adjusting the nut 700, the pre-compression amount of the spring piece 600 relative to the diaphragm assembly 300 can be changed, thereby achieving the purpose of adjusting the pressure, and has the advantage of easy adjustment.

[0058] Embodiment 2:

[0059] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the wind pressure sensor of the utility model, see Figure 4-Figure 8 .

[0060] refer to Figure 4 A first groove 211 for limiting the sealing ring 500 is formed at the bottom edge of the installation groove 210. The first groove 211 has a limiting installation effect on the sealing ring 500, thereby improving the stability of installation and sealing.

[0061] For example, the sealing ring 500 is an O-ring structure, which is used to seal the connection between the adjusting nut 700 and the installation groove 210, and is also used to play a certain role in limiting and supporting the edge of the spring piece 600. The sealing ring 500 can be made of rubber material, which has a certain elasticity and can produce a change in the amount of compression under the extrusion of the adjusting nut 700, thereby playing the effect of changing the pre-compression amount of the spring piece 600 relative to the diaphragm assembly 300. The shape of the first groove 211 matches the shape of the sealing ring 500, so as to play a better role in limiting the sealing ring 500, and also facilitate the alignment and installation of the sealing ring 500.

[0062] refer to Figure 5 and Figure 6 In some embodiments, the spring 600 is a planar rotating spring 600. Using the planar rotating spring 600 instead of the traditional spring structure has a good consistency effect, can improve the accuracy of the product, and is also convenient for adjusting the pre-compression amount.

[0063] A first through hole 610 is opened in the middle position of the spring piece 600, and a first step 341 is formed at the end of the guide column 340. The first step 341 abuts against the outside of the first through hole 610. The first step 341 cooperates with the first through hole 610 to play a limiting role, ensuring the stable installation effect of the spring piece 600, so as to facilitate the adjustment of the pre-compression amount of the spring piece 600 relative to the diaphragm assembly 300.

[0064] It can be understood that a first step 341 is formed on one end of the guide column 340 facing the spring sheet 600, and the circumferential size of the first step 341 is larger than the size of the first through hole 610. Therefore, the first step 341 and the first through hole 610 can be used to enable the guide column 340 and the spring sheet 600 to abut against each other. On the one hand, the guide column 340 can support the spring sheet 600, and on the other hand, the guide column 340 can also be used to transmit pressure difference and elastic force.

[0065] In some embodiments, the piston plate 320 and the guide post 340 are integrally formed to facilitate overall assembly and improve stability in use.

[0066] That is, the guide post 340 is formed upward from the middle of the piston plate 320 and is integrally formed with the piston plate 320, eliminating the process of assembling the piston plate 320 and the guide post 340, thereby improving assembly efficiency, avoiding assembly errors, and improving the stability of use. Of course, the guide post 340 and the piston plate 320 can also adopt the traditional split method, and a hollow cylinder for the alignment installation of the guide post 340 is provided on the piston plate 320 to play the role of connecting the guide post 340 and the piston plate 320.

[0067] It is understandable that in this embodiment, there is no limitation on whether the guide column 340 and the piston plate 320 are integrally formed or separated, and it can be adjusted according to actual production and processing requirements.

[0068] refer to Figure 7 In some embodiments, a second through hole 311 is formed in the middle of the wind pressure diaphragm 310, and the piston plate 320 is limitedly installed in the second through hole 311 to ensure accurate alignment and installation between the wind pressure diaphragm 310 and the piston plate 320, so as to improve the product's use stability and accuracy.

[0069] For example, the wind pressure diaphragm 310 is a circular wind pressure diaphragm 310, the second through hole 311 is a circular through hole, the piston plate 320 is a circular piston plate 320, and the size of the second through hole 311 matches the size of the piston plate 320, so that the piston plate 320 can be just installed in the second through hole 311, presenting an assembled connection relationship with the wind pressure diaphragm 310.

[0070] A second groove 321 is formed on the piston plate 320 at a position corresponding to the magnetic core 330 . The second groove 321 is used to limit the magnetic core 330 , facilitate the alignment installation of the magnetic core 330 , and improve the stable pushing effect of the piston plate 320 on the magnetic core 330 .

[0071] For example, the end of the magnetic core 330 close to the piston plate 320 is set as the first end, and the end of the magnetic core 330 close to the coil assembly 400 is set as the second end. The shape of the second groove 321 matches the shape of the first end of the magnetic core 330 to achieve the alignment installation and stable pushing effect of the magnetic core 330.

[0072] refer to Figure 8 In some embodiments, the coil assembly 400 includes an isolation mounting plate 410, an induction coil 420 and a circuit board 430. The induction coil 420 is connected to the circuit board 430. The circuit board 430 is arranged on the isolation mounting plate 410. The isolation mounting plate 410 is used for fixing the circuit board 430 and locking the circuit board 430 with the inside of the second shell 200. For example, the isolation mounting plate 410 is connected to the inner wall of the second shell 200 by connecting screws, which isolates and protects the circuit board 430 and the induction coil 420. At the same time, it can also improve the installation stability of the coil assembly 400, thereby improving the use accuracy of the wind pressure sensor.

[0073] Specifically, a coil skeleton 411 and a limiting column 412 are provided on the isolation mounting plate 410, and a third through hole 431 for the coil skeleton 411 to pass through and a fourth through hole 432 corresponding to the limiting column 412 are opened on the circuit board 430; the induction coil 420 is sleeved on the coil skeleton 411, and the coil skeleton 411 supports and limits the induction coil 420, so as to facilitate the connection and installation with the circuit board 430.

[0074] Since a coil skeleton 411 is provided on the isolation mounting plate 410, the induction coil 420 can be directly wound around the outer periphery of the coil skeleton 411 through automated equipment. After the winding is completed, the third through hole 431 on the circuit board 430 passes through the induction coil 420 through the correspondence between the limiting column 412 and the fourth through hole 432, and the circuit board 430 is accurately installed on the isolation mounting plate 410. Finally, the isolation mounting plate 410 and the inner wall of the second shell 200 are locked and connected so that the circuit board 430 is located between the isolation mounting plate 410 and the inner wall of the second shell 200. When installing the isolation mounting plate 410, since the induction coil 420 has been wound on the coil skeleton 411 and supported by the coil skeleton 411, there is no need to worry about the deformation of the induction coil 420 during the installation process, thereby effectively improving product quality.

[0075] Embodiment 3:

[0076] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the wind pressure sensor of the utility model, see Figure 9-11 .

[0077] The wind pressure sensor also includes a retaining spring 800, which is sleeved on the guide column 340 and is in a retaining relationship with the guide column 340, so that the position of the retaining spring 800 can be fixed, thereby limiting the position of the magnetic core 330 between the retaining spring 800 and the piston plate 320. The retaining spring 800 is used to limit the position of the magnetic core 330 in the axial direction, thereby improving the installation stability of the magnetic core 330.

[0078] In some embodiments, the wind pressure sensor further includes a mounting bracket 900 , which is connected to the first housing 100 or the second housing 200 , so as to facilitate installation of the wind pressure sensor and improve installation convenience and stability of the wind pressure sensor.

[0079] For example, the mounting bracket 900 establishes a connection relationship with the second shell 200, a slot is provided on the second shell 200, and correspondingly, a plug-in terminal is provided on the mounting bracket 900, and the plug-in terminal is inserted into the slot to realize the connection relationship between the mounting bracket 900 and the second shell 200.

[0080] In the utility model, the spring piece is installed in the installation groove outside the second shell, that is, the spring piece is installed in a post-installation manner, which has the advantages of convenient installation and convenient replacement compared with the original internal installation manner; by rotating the adjusting nut, the adjusting nut is pressed on the spring piece, and then the sealing ring is compressed, that is, by adjusting the compression amount of the sealing ring through the adjusting nut, the pre-compression amount of the spring piece relative to the diaphragm assembly can be changed, thereby achieving the purpose of adjusting the pressure, and has the advantage of easy adjustment.
