[0033] Example

[0034] Firstly, please refer to Figures 1 to 6 The present invention proposes a tire pressure sensor 10 that is easy to assemble, comprising: a housing assembly 11, a tire pressure detection assembly 13 and a guide assembly 12. The housing assembly 11 has a receiving cavity 112, the guide assembly 12 is assembled in the receiving cavity 112, and the guide assembly 12 guides the tire pressure detection assembly 13 to move in the assembly direction, so that the tire pressure detection assembly 13 is assembled in the receiving cavity 112.

[0035] In practical applications, an external force is applied to the tire pressure monitoring component 13, causing it to move along the guide component 12 into the receiving cavity 112. During this movement, the guide component 12 guides and positions the tire pressure monitoring component 13, ensuring it moves according to a preset assembly direction and path. When the tire pressure monitoring component 13 reaches the preset position within the receiving cavity 112, the assembly of the tire pressure monitoring component 13 into the housing component 11 is complete.

[0036] The tire pressure sensor 10 proposed in this embodiment is easy to assemble and disassemble. The guide component 12 guides the assembly of the tire pressure detection component 13, enabling the tire pressure detection component 13 to be quickly and accurately assembled into the receiving cavity 112 of the housing component 11. This reduces the time for manual alignment and adjustment, and improves assembly efficiency. At the same time, the guiding effect of the guide component 12 ensures that the assembly direction of the tire pressure detection component 13 is accurate, improving assembly accuracy and product quality.

[0037] Please see Figures 3 to 5 The guide assembly 12 includes a guide post 121 and a guide hole 122. The guide post 121 is mounted on the bottom wall of the receiving cavity 112, and the guide hole 122 is mounted on the tire pressure detection assembly 13. The guide post 121 is inserted into the guide hole 122, and the guide hole 122 moves along the axis of the guide post 121, so that the tire pressure detection assembly 13 moves relative to the housing assembly 11.

[0038] Specifically, when assembling the tire pressure monitoring component 13 to the housing component 11, firstly, the tire pressure monitoring component 13 is brought close to the opening of the receiving cavity 112 of the housing component 11, so that the guide post 121 is aligned with the guide hole 122 and inserted therein; then, along the axial direction of the guide post 121, the tire pressure monitoring component 13 is pushed, so that it moves into the receiving cavity 112 with the cooperation of the guide post 121 and the guide hole 122, until the tire pressure monitoring component 13 is fully assembled into the preset position in the receiving cavity 112, thereby completing the assembly of the tire pressure monitoring component 13 on the housing component 11. The cooperation of the guide post 121 and the guide hole 122 provides assembly guidance for the assembly of the tire pressure monitoring component 13, avoiding the phenomenon of skewness and jamming of the tire pressure monitoring component 13 when manually operated or pressed one by one by traditional pressing equipment, making the process of assembling the tire pressure monitoring component 13 to the housing component 11 smoother and improving the assembly efficiency of the tire pressure monitoring component 13 to the housing component 11.

[0039] In one embodiment, the guide post 121 and the guide hole 122 are clearance-fitted, meaning the size of the guide hole 122 is slightly larger than the size of the guide post 121, and there is a certain gap between them. When the tire pressure monitoring assembly 13 is assembled, the guide post 121 is inserted into the guide hole 122. Due to the gap, the tire pressure monitoring assembly 13 can move freely along the axial direction of the guide post 121 without jamming, thus improving the assembly efficiency of the tire pressure monitoring assembly 13 to the housing assembly 11.

[0040] Please see Figures 2 to 3 The housing assembly 11 includes an upper housing 111 and a bottom cover 115, a receiving cavity 112 located in the upper housing 111, and the bottom cover 115 fitted onto the upper housing 111 to lock the tire pressure monitoring assembly 13 within the receiving cavity 112.

[0041] Specifically, the upper shell 111 has a receiving cavity 112 for assembling the tire pressure monitoring component 13. After the tire pressure monitoring component 13 is assembled in the receiving cavity 112, the bottom cover 115 is assembled onto the upper shell 111 to lock the tire pressure monitoring component 13 in the receiving cavity 112.

[0042] Please see Figure 3 The housing assembly 11 also includes a support platform 114 and a flexible snap-fit ​​arm 113. The support platform 114 is mounted on the bottom wall of the receiving cavity 112, and the flexible snap-fit ​​arm 113 is mounted on the side wall of the receiving cavity 112. The support platform 114 and the flexible snap-fit ​​arm 113 cooperate with each other to limit the longitudinal movement of the tire pressure detection assembly 13 in the receiving cavity 112.

[0043] Specifically, the support platform 114 is mounted on the bottom wall of the receiving cavity 112. When the tire pressure monitoring component 13 is installed in the receiving cavity 112, the support platform 114 supports the bottom of the tire pressure monitoring component 13, restricting its downward movement. The elastic locking arm 113 is mounted on the side wall of the receiving cavity 112. When the tire pressure monitoring component 13 is installed in the receiving cavity 112, the elastic locking arm 113 is squeezed and deformed. When the tire pressure monitoring component 13 reaches the predetermined position, the elastic locking arm 113 uses its own elastic restoring force to lock the tire pressure monitoring component 13 in the receiving cavity 112, thereby restricting the tire pressure monitoring component 13 from moving upward. The support platform 114 and the elastic locking arm 113 cooperate with each other to limit the tire pressure monitoring component 13 from both the top and bottom directions, so as to form a longitudinal constraint, so that the tire pressure monitoring component will not move longitudinally when the vehicle is driving on complex road conditions, thus improving the operational stability of the tire pressure monitoring component 13.

[0044] Please see Figure 5 The tire pressure monitoring assembly 13 includes: an electronic control board 131, a detection element 134, and an onboard antenna 132. A guide hole 122 is mounted on the electronic control board 131. The detection element 134 and the onboard antenna 132 are both electrically connected to the electronic control board 131. The onboard antenna 132 is vertically connected to the electronic control board 131.

[0045] It should be noted that the tire pressure monitoring assembly 13 also includes a power supply 133, which is electrically connected to the electronic control board 131, the detection element 134, and the onboard antenna 132, and supplies power to the electronic control board 131, the detection element 134, and the onboard antenna 132. The upper shell 111 of the housing assembly 11 has a through hole 1112 corresponding to the detection element 134. When the easily assembled tire pressure sensor 10 is applied in the tire, the gas inside the tire contacts the detection element 134 through the through hole 1112, simultaneously measuring the air pressure and temperature inside the tire.

[0046] Specifically, the onboard antenna 132 is vertically connected to the electronic control board 131, avoiding mutual interference between the onboard antenna 132 and the electronic components on the electronic control board 131, thus improving the stability of signal transmission. At the same time, the onboard antenna 132 does not need to surround the electronic control board 131, eliminating the need for additional space around the electronic control board 131, improving the utilization rate of the housing cavity 112. Furthermore, the onboard antenna 132 is smaller in size than an antenna with the same transmission power, thereby reducing the size of the tire pressure monitoring assembly 13.

[0047] In one embodiment, please refer to Figures 3 to 5 The upper shell 111 has a protective groove 1114 inside, and the onboard antenna 132 extends into the protective groove 1114.

[0048] Specifically, the onboard antenna 132 is vertically connected to the electronic control board 131 and placed in the protective groove 1114 of the upper shell 111, which improves the utilization rate of the receiving cavity 112 and makes the entire tire pressure sensor 10 structure more compact. The onboard antenna 132 extends into the protective groove 1114 of the upper shell 111, which reduces electromagnetic interference between the onboard antenna 132 and other electronic components on the electronic control board 131 and improves the stability of signal transmission.

[0049] Please see Figure 1 and Figure 2 The tire pressure sensor 10, which is easy to assemble, also includes a valve assembly 15 and a fixing screw 14. The upper housing 111 is provided with an adjustment groove 1111, and one end of the fixing screw 14 passes through the adjustment groove 1111 and is connected to the valve assembly 15.

[0050] Specifically, the valve assembly 15 is connected to the housing assembly 11 via the fixing screw 14, facilitating the installation and removal of the tire pressure sensor 10 on the tire. An adjustment groove 1111 is provided on the upper housing 111 to increase the lateral swing range of the fixing screw 14, thereby improving the adaptability of the tire pressure sensor 10 and making it suitable for various wheel rims. When the wheel rim angle is small, the valve stem moves downwards under the action of external force; when the wheel rim angle is large, the process is the opposite.

[0051] Please see Figure 2 The fixing screw 14 is provided with a fitting part 144 at the position corresponding to the adjustment groove 1111. The fitting part 144 is fitted into the adjustment groove 1111, and the width of the fitting part 144 is adapted to the width of the adjustment groove 1111.

[0052] Specifically, at least one limiting surface 1441 is provided on the periphery of the fitting part 144. The limiting surface 1441 cooperates with the corresponding side wall of the adjusting groove 1111 to limit the rotation of the fixing screw 14. In this embodiment, four limiting surfaces 1441 are provided on the periphery of the fitting part 144. The width of the fitting part 144 is adapted to the width of the adjusting groove 1111. When the fixing screw 14 passes through the adjusting groove 1111 and connects to the valve assembly 15, the fitting part 144 on the fixing screw 14 is fitted into the adjusting groove 1111, and the limiting surface 1441 abuts against the two side walls of the adjusting groove 1111, thereby preventing the fixing screw 14 from rotating relative to the adjusting groove 1111.

[0053] Please refer to it again. Figure 2 The fixing screw 14 includes a screw head 141 and a screw post 142. The screw post 142 passes through the adjustment groove 1111 and is connected to the valve assembly 15. The screw head 141 is provided with at least one anti-slip strip 143 on the side near the screw post 142. When the valve assembly 15 is connected to the housing assembly 11, the anti-slip strip 143 abuts against the upper housing 111.

[0054] Specifically, by tightening the fixing screw 14, the anti-slip strip 143 is brought into close contact with the upper housing 111, generating static friction to prevent the screw from loosening during use and to ensure the connection stability between the valve assembly 15 and the housing assembly 11, thereby improving the stability of the tire pressure sensor 10, which is easy to assemble, during tire operation.

[0055] Please refer to it again. Figure 2 The upper housing 111 has a connecting cavity 1113 on the side near the valve assembly 15. The adjusting groove 1111 communicates with the connecting cavity 1113. The valve assembly 15 has a connector 151 at the position corresponding to the connecting cavity 1113. One end of the screw stud 142 passes through the adjusting groove 1111 and the connecting cavity 1113, so that the connector 151 is connected to the connecting cavity 1113.

[0056] Specifically, the fixing screw 14 passes sequentially through the adjusting groove 1111 and the connecting cavity 1113 of the upper housing 111 and connects to the connector 151 of the valve assembly 15, forming a relatively locking mechanical structure. This allows the easily assembled tire pressure sensor 10 to be stably installed on the tire, preventing the sensor from loosening or falling off due to vibrations, centrifugal force, or tire deformation during vehicle operation. Simultaneously, the connecting cavity 1113 provides a precise mating space for the connection between the fixing screw 14 and the connector 151, ensuring that the fixing screw 14 can accurately connect to the connector 151, achieving a secure connection between the housing assembly 11 and the valve assembly 15.

[0057] In this embodiment, the inner wall of the connecting cavity 1113 has the same curvature as the outer wall of the connector 151, making the stress distribution on the contact surface of the connector 151 and the connecting cavity 1113 uniform. The stress generated when subjected to centrifugal force from tire rotation or vibration during vehicle operation can be uniformly transmitted to the entire contact surface, rather than concentrated in a local area, avoiding stress concentration and improving the connection stability between the valve assembly 15 and the housing assembly 11.

[0058] Secondly, please refer to Figure 6 The present invention provides a tire, comprising: a rim 20 and at least one tire pressure sensor 10 as described above for easy assembly, wherein the tire pressure sensor 10 is assembled on the rim 20 and a portion of the structure of the tire pressure sensor 10 is located within the rim 20.

[0059] Compared with the prior art, the tire pressure sensor 10 proposed in this utility model is easy to assemble. The guide component 12 guides the assembly of the tire pressure detection component 13, enabling the tire pressure detection component 13 to be quickly and accurately assembled into the receiving cavity 112 of the housing component 11. This reduces the time for manual alignment and adjustment, and improves assembly efficiency. At the same time, the guiding effect of the guide component 12 ensures that the assembly direction of the tire pressure detection component 13 is accurate, improving assembly precision and product quality.

[0060] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
