[0027] Please also read Figure 1-3 The embodiment of the present invention provides a tire pressure sensor 100, which is installed on a wheel frame of a tire, and includes a sensor body 10, a valve assembly 20 detachably connected to the sensor body, a locking member 30, an elastic supporting member 40, and a button 50. The connecting end 21 of the valve assembly 20 is provided with a block assembly 211 that can be extended and retracted along the radial direction of the connecting end; the locking member 30 is arranged in the sensor body 10, and when the sensor body 10 and the valve assembly 20 are connected, the locking member 30 limits the block assembly 211; the button 50 is arranged in the sensor body 10, and when the button 50 is subjected to an external force, the external force is transmitted to the block assembly 211, so that the locking member 30 releases the limit on the block assembly 211.

[0028] In some other embodiments, the block assembly 211 is a non-retractable protrusion that is perpendicular to the side of the connecting end 21 of the valve assembly 20 .

[0029] The sensor body 10 includes a first shell 11 and a second shell 12, and the first shell 11 and the second shell 12 are engaged with each other. A receiving groove 111 for accommodating the locking member 30, the elastic supporting member 40 and the button 50 is provided on a side of the first shell 11 away from the second shell 12. The first shell 11 is also provided with a valve assembly hole 112 perpendicular to the receiving groove 111. The receiving groove 111 and the valve assembly hole 112 are connected to each other. After the sensor body 10 and the valve assembly 20 are connected, the locking member 30 is located at the bottom of the receiving groove 111 and clamps the clamping block assembly 211. Specifically, a fixing block 1111 is provided at the bottom of the receiving groove 111, and the bottom of the receiving groove 111 is separated by the fixing block 1111 to form a clamping groove 1112 located on the left and right sides of the fixing block 1111. The two slots 1112 are respectively located at the left and right opposite sides of the fixing block 1111 , and both slots 1112 are connected to the valve assembly hole 112 (ie, the accommodating groove 111 is connected to the valve assembly hole 112 through the slots 1112 ).

[0030] The connecting end 21 of the valve assembly 20 is in the shape of a rectangular parallelepiped, and a block assembly 211 is respectively arranged on the left and right sides thereof, which can be extended and retracted relative to the side of the connecting end 21. In a normal state, the block assembly 211 protrudes from the side of the connecting end 21, and when the block assembly 211 is squeezed, it can be retracted to be flush with the side of the connecting end 21. For details, please refer to Figure 5 The left and right sides of the connecting end 21 are respectively provided with receiving grooves 212. The block assembly 211 includes a block 2111 and an elastic component 2112. One end of the block 2111 is semi-spherical and protrudes from the side of the connecting end 21; the other end is located in the receiving groove 212, and the block 2111 can slide in the receiving groove 212. The elastic component 2112 is located in the receiving groove 212, and one end of the elastic component 2112 abuts against the other end of the block 2111, and the other end of the elastic component 2112 abuts against the fixing block 1111.

[0031] In some other embodiments, the connection end 21 of the valve assembly 20 may also be cylindrical, polyhedral, etc.

[0032] See also Figure 3 , Figure 3: is a schematic exploded view of the structure of the tire pressure sensor. In the present embodiment, the locking member 30 is U-shaped and includes a base plate 31. The left and right ends of the base plate 31 extend downward in a direction perpendicular to the base plate 31 to form a first extension portion 32 and a second extension portion 33, respectively. A through hole 311 is provided in the center of the base plate 31. The first extension portion 32 and the second extension portion 33 are provided with a first fixing hole 321 and a second fixing hole 331 at one end away from the base plate 31, and the first fixing hole 321 and the second fixing hole 331 are both through holes. The shapes of the first fixing hole 321 and the second fixing hole 331 are the same as the cross-sectional shape of the block 2111, and in the present embodiment, both are circular. After the sensor body 10 and the valve assembly 20 are connected, the two blocks 2111 are respectively embedded in the first fixing hole 321 and the second fixing hole 331 (see FIG. 2 ). Figure 4 The outer surface of the other end of the first extension portion 32 (i.e., the end connected to the bottom plate 31) is provided with a first stop block 322, and the outer surface of the other end of the second extension portion 33 (i.e., the end connected to the bottom plate 31) is provided with a second stop block 332 (see Figure 4 The first stop block 322 and the second stop block 332 are used to hold the button 50 to prevent the button 50 from being separated from the receiving groove 111. The first extension portion 32 and the second extension portion 33 are respectively embedded in the two slots 1112, the bottom plate 31 is closely attached to the upper surface of the fixing block 1111, and one end of the first extension portion 32 and one end of the second extension portion 33 are located in the valve assembly hole 112.

[0033] It is understandable that in some other embodiments, the number of the block assembly 211 may be only one, located on the left or right side of the connecting end 21. Accordingly, the locking member 30 only needs to have the first extension portion 32, but not the second extension portion 33, and the number of the card slot 1112 is also only one.

[0034] In this embodiment, the elastic resisting member 40 is a spring, one end of which resists the button 50, and the other end passes through the through hole 311 and resists the bottom of the receiving groove 111. It is understandable that in some other embodiments, the elastic resisting member 40 can also be a spring or other elastic element, and the number of the elastic resisting members 40 can also be two, three or more. Figure 3 and Figure 4The button 50 is U-shaped and includes a bottom wall 51. The left and right ends of the bottom wall 51 extend downward in a direction perpendicular to the bottom wall 51 to form a first side wall 52 and a second side wall 53, respectively. The bottom wall 51 is provided with an anti-slip structure (not shown in the figure). The anti-slip structure can be a protruding structure with a texture, or a convex or concave structure with a logo or character printed on it. The first side wall 52 is provided with a first bent portion 521 bent outwardly at one end away from the bottom wall 51, and the first bent portion 521 abuts against one end of the block 2111; a first bent portion 522 bent inwardly is provided between the first bent portion 521 of the first side wall 52 and the other end of the first side wall 52, and the first bent portion 522 abuts against the first stop block 322. A second bent portion 531 bent outward is provided at one end of the second side wall 53 away from the bottom wall 51, and the second bent portion 531 abuts against one end of the other blocking block 2111; a second bent portion 532 bent inward is provided between the second bent portion 531 of the second side wall 53 and the other end of the second side wall 53, and the second bent portion 532 abuts against the second stop block 332.

[0035] When the button 50 is subjected to an external force, the external force is transmitted to the block assembly 211, so that the locking member 30 releases the restriction on the block assembly 211. Specifically, the button 50 can slide up and down in the receiving groove 111. When the button 50 is pressed, the button 50 moves downward, and the first curved portion 521 and the second curved portion 531 respectively squeeze the blocks 2111 disposed on both sides of the connecting end 21, so that the blocks 2111 gradually shrink into the receiving groove 212, until the blocks 2111 are completely shrunk into the receiving groove 212 and blocked by the first curved portion 522 and the second curved portion 532. At this time, the connecting end 21 of the valve assembly 20 can be easily pulled out of the valve assembly hole 112. It is understandable that, in some other embodiments, the elastic supporting member 40 may no longer be a separate component, and the elastic supporting member 40 is a spring sheet, one end of the elastic supporting member 40 is fixedly connected to the button 50 (specifically, one end of the elastic supporting member 40 is fixedly connected to the lower surface of the bottom wall 51), and the other end is suspended and abuts against the upper surface of the bottom plate 31 of the locking member 30.

[0036] It is understandable that, in some other embodiments, the locking member 30 may not be a separate component, and the locking member 30 and the first shell 11 are an integral structure (that is, a structure with the same shape as the locking member 30 is provided at the bottom of the accommodating groove 111, and the structure is integral with the first shell 11).

[0037] Installation process of the tire pressure sensor 100: When the tire pressure sensor 100 needs to be used, it is only necessary to align the connection end 21 of the valve assembly 20 with the valve assembly hole 112, and forcefully insert the connection end 21 into the valve assembly hole 112. During the insertion process, the block 2111 is squeezed and completely retracted into the receiving groove 212 until the block 2111 is aligned with the first fixing hole 321 and the second fixing hole 331, and the block 2111 extends out of the receiving groove 212 and is embedded in the first fixing hole 321 and the second fixing hole 331, thereby preventing the connection end 21 from being separated from the valve assembly hole 112, thereby completing the installation of the valve assembly 20 and the sensor body 10.

[0038] The disassembly process of the tire pressure sensor 100: When the button 50 is pressed, the button 50 moves downward, and the first curved portion 521 and the second curved portion 531 respectively squeeze the blocks 2111 arranged on both sides of the connecting end 21, so that the blocks 2111 gradually shrink into the receiving groove 212, until the blocks 2111 are completely shrunk into the receiving groove 212 and blocked by the first curved portion 522 and the second curved portion 532. At this time, the connecting end 21 of the valve assembly 20 can be easily pulled out of the valve assembly hole 112. Then release the button 50, and the button 50 moves upward under the elastic force of the elastic supporting member 40, and quickly resets.

[0039] It can be seen that the tire pressure sensor 100 provided in the embodiment of the present invention can be installed and used by inserting the connection end 21 of the valve assembly 20 into the valve assembly hole 112, and the locking member 30 can clamp the blocks 2111 arranged on both sides of the connection end 21, so that the valve assembly 20 and the sensor body 10 are installed and fixed. When disassembly is required, the button 50 is pressed so that the button 50 squeezes the block 2111, so that the locking member 30 no longer clamps the block 2111, thereby allowing the connection end 21 to be pulled out of the valve assembly hole 112. The entire installation and disassembly process is simple and quick, and after the valve assembly 20 and the sensor body 10 are installed, their connection is very firm.
