Description

Technical Field

[0001] This application relates to the field of sensor technology, specifically to a tire pressure sensor. Background Technology

[0002] Driving safety is not only related to the lives of drivers and passengers, but also involves the safety of other road users (pedestrians, cyclists, etc.). Tire pressure has a significant impact on driving safety; excessively low or high tire pressure can easily lead to tire blowouts, accelerated tire wear, and other problems, seriously affecting the stability and safety of the vehicle. Therefore, tire pressure monitoring is of paramount importance for driving safety.

[0003] Currently, tire pressure sensors primarily monitor tire pressure and temperature in real time and issue alerts when abnormalities occur to improve driving safety. However, existing tire pressure sensors have a large number of parts, making the assembly process cumbersome. Furthermore, the small size of the spring makes it difficult to grip, and it is prone to falling off during tire pressure sensor assembly, leading to component loss. Utility Model Content

[0004] In view of the above problems, this application provides a tire pressure sensor to solve the problems of cumbersome assembly and easy loss of parts in existing tire pressure sensors.

[0005] According to one aspect of the embodiments of this application, a tire pressure sensor is provided, comprising: a sensor body; a locking member disposed on the sensor body for locking the sensor body to an air valve; a button disposed on the sensor body and slidably connected to the locking member, the button being used to disengage the air valve from the locking member when pressed; and a soft rubber elastic member integrally formed with at least one of the locking member and the button, the soft rubber elastic member including a support portion and a deformation post, the support portion having a groove-shaped structure, and the outer periphery of the support portion being connected to one of the locking member or the button, one end of the deformation post being connected to the bottom of the groove of the support portion, and the other end of the deformation post being connected to the other of the locking member or the button, the deformation post being used to deform when the button is pressed, and the internal space of the support portion being used to provide deformation space for the deformation post and limit the deformation of the deformation post.

[0006] In one alternative embodiment, a recess is formed on the outer surface of the support portion on the side opposite to the deformation post, the support portion is used to deform when the button is pressed, and the recess is used to provide deformation space for the support portion.

[0007] In one alternative, the bottom of the groove of the support protrudes towards the interior of the support to form a convex hull, and a deformation post is connected to the convex hull, which is used to bend and deform into a recess when the button is pressed.

[0008] In one alternative configuration, the deformation column is connected to the middle position of the bottom of the support.

[0009] In one alternative approach, the soft rubber elastic element and the locking element are integrated into a single structure.

[0010] In one alternative embodiment, the locking element has a through hole, and the soft rubber elastic element is integrally inserted into the through hole.

[0011] In one alternative configuration, one end of the deformable post abuts against the button, while the other end is connected to the bottom of the groove in the support.

[0012] In one alternative embodiment, the outer wall of the support at one end of the slot is connected to the inner wall of the through hole.

[0013] In one alternative approach, the sensor body is provided with a mounting groove, and the outer wall of the support part on the side opposite to the deformation column abuts against the bottom of the mounting groove.

[0014] In one alternative embodiment, the outer periphery of the support protrudes outward to form a joint, which connects to the surface surrounding the opening of the through hole.

[0015] This application embodiment integrates the soft rubber elastic element with the locking element or button into a single structure, effectively reducing the number of parts. This not only simplifies the assembly of the tire pressure sensor but also reduces the probability of part loss. Furthermore, when the button is pressed, the deformation of the deformation post ensures that the button can slide a sufficient distance to disengage the valve from the locking element. The support portion further limits the deformation of the deformation post, preventing excessive deformation and ensuring its service life.

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0041] Please see Figure 1 , Figure 1 A cross-sectional view of a conventional tire pressure sensor is shown. The conventional tire pressure sensor includes a body 110, a snap-fit ​​member 120, a pressing member 130, and a spring 140. The body 110 has a connection hole 111 for connecting to a valve stem 200 and a insertion slot 112 for receiving the snap-fit ​​member 120, the pressing member 130, and the spring 140, and the connection hole 111 and the insertion slot 112 are connected.

[0042] When assembling the tire pressure sensor, first insert the snap-fit ​​component 120 into the insertion slot 112 in the direction shown by arrow A, so that the limiting hole 121 on the snap-fit ​​component 120 aligns with the opening of the limiting groove 113 on the main body 110. Then, pass the spring 140 through the limiting hole 121 in the direction shown by arrow A and insert it into the limiting groove 113. Finally, insert the pressing component 130 into the insertion slot 112 in the direction shown by arrow A and slide it in connection with the snap-fit ​​component 120. At this time, the two ends of the spring 140 abut against the limiting groove 113 and the bottom of the pressing component 130, respectively. In this process, because the tire pressure sensor has a large number of parts, and each part needs to be assembled in sequence, the assembly process is complex and cumbersome.

[0043] In addition, the tire pressure sensor is mainly used to detect tire pressure and temperature inside the tire. It is typically mounted on the inside of the wheel hub and connected to the valve stem. Specifically, when installing the tire pressure sensor, the valve stem 200 is inserted into the connection hole 111 of the main body 110, and the ball bearing 210 on the valve stem 200 engages with the locking member 120, thereby locking the tire pressure sensor onto the valve stem 200. When it is necessary to remove the tire pressure sensor, pressure is applied to the pressing member 130 in the direction shown by arrow A, causing the pressing member 130 to slide relative to the locking member 120 in the direction shown by arrow A. The unlocking part 131 on the pressing member 130 then pushes the ball bearing 210 into the valve stem 200, thereby disengaging the valve stem 200 from the locking member 120.

[0044] Since a braking system needs to be installed on the wheel hub, if the tire pressure sensor is too large, it may interfere with the braking system, affecting its normal operation. Furthermore, the wheel hub needs to be sealed to the tire, but space on the hub is limited. If the tire pressure sensor is too large, it may interfere with the tire, leading to a poor tire seal or increasing the difficulty of tire installation. Therefore, tire pressure sensors are usually small, which makes the components on the sensor (i.e., the snap-fit ​​part 120, the pressing part 130, and the spring 140, etc.) small. This makes it difficult to grasp the components, making them prone to falling off during assembly. Because the spring 140 is elastic, it is very easy to lose it after falling.

[0045] Based on this, it is possible to consider designing some parts as an integral structure to reduce the number of parts and simplify assembly. Specifically, after the tire pressure sensor is assembled, the spring 140 is mainly used to compress the pressing member 130 when it is pressed and to provide elastic force to the pressing member 130 so that the pressing member 130 can return to its original position when released. Therefore, designing the spring 140, the snap-fit ​​member 120, and at least one of the pressing member 130 as an integral structure will not affect the disassembly and assembly of the tire pressure sensor and can also reduce the number of parts.

[0046] However, to ensure the spring 140 can repeatedly undergo elastic deformation, it is typically made of high-carbon steel, stainless steel, or silicon-manganese alloy, and requires special manufacturing processes (such as quenching and tempering) to achieve elasticity. The snap-fit ​​component 120 and the pressing component 130 usually need high hardness or wear resistance and may be made of cast iron, aluminum alloy, or engineering plastics. The heat treatment processes for these materials (such as die casting and injection molding) are incompatible with the processing methods for spring materials. When the spring 140 is directly integrated with the snap-fit ​​component 120 or the pressing component 130, if the heat treatment process for the snap-fit ​​component 120 and the pressing component 130 is used in the production of the parts, the strength of the spring area will be insufficient, affecting the elastic deformation of the spring 140. If the spring manufacturing process is used in the production of the parts, the brittleness of the non-spring areas will increase, resulting in insufficient hardness of the snap-fit ​​component 120 and the pressing component 130. Furthermore, stress concentration points are easily formed at the connection between the spring 140 and the snap-fit ​​component 120 and the pressing component 130, making the connection prone to fatigue fracture.

[0047] Therefore, in order to reduce the number of parts while meeting the pressing and resetting requirements of the button, this application provides a tire pressure sensor. By designing at least one of the soft rubber elastic element, locking element (i.e., snap-fit ​​element 120), and button (i.e., pressing element 130) into an integrated structure, the number of parts is effectively reduced, the assembly difficulty of the tire pressure sensor is lowered, and the probability of part loss is also reduced. Furthermore, by designing the structure of the soft rubber elastic element, it includes a deformable deformation post and a support portion that limits the deformation degree of the deformation post, ensuring that the button can be pressed normally to disengage the air valve from the locking element, and that the button can reset normally. Specifically, the deformation post can deform when the button is pressed to provide sufficient sliding distance for the button to disengage the air valve from the locking element, while the support portion can provide deformation space to the deformation post when the button is pressed and limit the deformation amount of the deformation post, preventing excessive deformation and ensuring service life.

[0048] According to one aspect of the embodiments of this application, a tire pressure sensor is provided; please refer to the following for details. Figures 2 to 4 , Figure 2 A 3D view of the tire pressure sensor is shown. Figure 3 A cross-sectional view of the tire pressure sensor is shown. Figure 4 An exploded view of a tire pressure sensor is shown. The tire pressure sensor 300 includes a sensor body 310, a locking element 320, a button 330, and a soft rubber elastic element 340.

[0049] like Figures 3 to 4 As shown, the locking member 320 is disposed on the sensor body 310 and is used to lock the sensor body 310 onto the air nozzle. The button 330 is disposed on the sensor body 310 and is slidably connected to the locking member 320. The button 330 is used to disengage the air nozzle from the locking member 320 when pressed. The soft rubber elastic element 340 is integrally formed with at least one of the locking element 320 and the button 330. The soft rubber elastic element 340 includes a support portion 341 and a deformation post 342. The support portion 341 has a groove-shaped structure, and its outer periphery is connected to one of the locking element 320 or the button 330. One end of the deformation post 342 is connected to the bottom of the groove of the support portion 341, and the other end of the deformation post 342 is connected to the other of the locking element 320 or the button 330. The deformation post 342 is used to deform when the button 330 is pressed. The internal space of the support portion 341 is used to provide deformation space for the deformation post 342 and limit the deformation of the deformation post 342.

[0050] The sensor body 310 is the main structure of the tire pressure sensor 300, such as... Figure 3 and Figure 4As shown, the sensor body 310 has a mounting hole 311 for connecting to the air valve and a receiving groove 312 for accommodating the locking member 320, the button 330 and the soft rubber elastic member 340. The mounting hole 311 and the receiving groove 312 are connected. When assembling the tire pressure sensor 300, the air valve is inserted into the mounting hole 311 and the snap-fit ​​part on the air valve is snapped into the locking member 320 in the receiving groove 312.

[0051] like Figure 5 As shown, Figure 5 A partial structure of the tire pressure sensor is shown. The locking member 320 may include a base plate 321, with both ends of the base plate 321 facing... Figure 5 The insertion portion 322 extends in the direction indicated by the middle arrow B. By inserting the insertion portion 322 into the receiving groove 312, the locking member 320 is assembled onto the sensor body 310. In addition, the insertion portion 322 of the locking member 320 has a snap-fit ​​hole 323, which is used to snap into a snap-fit ​​portion on the valve stem to lock and fix the tire pressure sensor 300 onto the valve stem.

[0052] Specifically, such as Figure 4 , Figure 5 and Figure 6 As shown, Figure 6 A partial cross-sectional view of the tire pressure sensor is shown. The locking part on the valve 200 can be a ball bearing 210, and the locking member 320 has a locking hole 323. When assembling the tire pressure sensor 300, first move the locking member 320 along... Figure 4 Insert the nozzle 200 into the receiving slot 312 in the direction indicated by the middle arrow B, and then insert the nozzle 200 along the direction indicated by the middle arrow B. Figure 4 The valve stem is inserted into the mounting hole 311 in the direction indicated by the middle arrow C, so that the ball bearing 210 on the valve stem 200 passes through the snap-fit ​​hole 323 on the locking member 320, thereby locking and fixing the tire pressure sensor 300 onto the valve stem 200.

[0053] Button 330 is used to remove the tire pressure sensor 300 from the valve stem 200, specifically, as follows: Figure 4 and Figure 6 As shown, button 330 includes a pressing part 331 and an abutting part 332. When assembling the tire pressure sensor 300, button 330 is pressed along... Figure 4 The sensor is inserted into the receiving slot 312 in the direction indicated by arrow B, with the pressing part 331 exposed outside the sensor body, so that the abutting part 332 abuts against the locking part (i.e., the sliding ball 210) on the air nozzle 200 (as shown by arrow B). Figure 6 (As shown). When removing the tire pressure sensor 300, apply pressure along the edge of the pressing part 331. Figure 6 The pressure in the direction indicated by the middle arrow B causes the button 330 to move relative to the locking member 320 along... Figure 6 Slide in the direction indicated by the middle arrow B, and the contact part 332 slides along the direction indicated by the middle arrow B. Figure 6As the ball moves in the direction indicated by the middle arrow B, it will push the ball 210 into the air nozzle 200, causing the ball 210 to disengage from the locking hole 323, thereby disengaging the air nozzle 200 from the locking member 320.

[0054] The soft rubber elastic element 340 provides a restoring elastic force to the button 330. The soft rubber elastic element 340 can be integrated with the locking element 320 to improve the tactile feel of the button 330, or it can be integrated with the button 330 itself. Alternatively, the button 330, the soft rubber elastic element 340, and the locking element 320 can be designed as a single unit. The soft rubber elastic element 340 can be made of materials such as silicone or rubber, and can be injection molded to form a single unit with at least one of the locking element 320 and the button 330.

[0055] As an example, when the soft rubber elastic element 340 and the locking element 320 are an integral structure, such as Figure 4 , Figure 5 and Figure 6 As shown, a through hole 410 can be formed in the locking member 320, and the soft rubber elastic member 340 can be integrally inserted into the through hole 410. This structural design allows for the formation of a rough inner sidewall within the through hole 410 during its formation, thereby improving the stability of the connection between the outer peripheral sidewall of the soft rubber elastic member 340 and the inner sidewall of the through hole 410. Specifically, as... Figure 3 and Figure 6 As shown, the support portion 341 is inserted into the through hole 410, and the outer sidewall of the support portion 341 is connected to the inner sidewall of the through hole 410 to form an integral structure. The support portion 341 can be as follows: Figure 6 The groove can be connected to the inner wall of the through hole 410 through the outer wall of one end of the groove, or it can be connected to the inner wall of the through hole 410 through the outer wall of the bottom end of the groove.

[0056] In addition, it is also possible to Figure 6 The soft rubber elastic element 340 shown is inverted, with the deformation post 342 inserted into the through hole 410, and the outer side wall of the deformation post 342 connected to the inner side wall of the through hole 410 to form an integral structure. At this time, one end of the deformation post 342 is connected to the support part 341, and the other end is connected to the locking member 320. The support part 341 is located between the locking member 320 and the button 330, and its outer periphery is connected to the bottom of the button 330.

[0057] Of course, the soft rubber elastic element 340 can also abut between the top of the locking element 320 and the bottom of the button 330. Specifically, the bottom surface of the support 341 can be integrally connected to the top surface of the locking element 320, and the top surface of the deformation post 342 can be connected to the bottom surface of the button 330; or, Figure 6The soft rubber elastic element 340 shown is inverted, and the bottom surface of the deformation column 342 is integrally connected to the top surface of the locking element 320, while the top surface of the support part 341 is connected to the bottom surface of the button 330.

[0058] In another embodiment, the soft rubber elastic element 340 can also be integrally formed with the button 330. Specifically, a through hole 410 can be formed on the button 330, and the soft rubber elastic element 340 can be integrally inserted into the through hole 410. Alternatively, the top surface of the soft rubber elastic element 340 can be integrally bonded to the bottom surface of the button 330. Of course, the soft rubber elastic element 340 can be in the form of... Figure 6 The shown configuration allows the deformation post 342 to be integrally inserted into the through hole on the button 330, or the top surface of the deformation post 342 to be integrally connected to the bottom surface of the button 330, with the support 341 connected to the locking member 320; alternatively, the deformation post 342 can be integrally connected to the bottom surface of the button 330. Figure 6 The soft rubber elastic element 340 shown is inverted, with the support part 341 inserted into the through hole on the button 330 in an integral form, or the top surface of the support part 341 is integrally attached to the bottom surface of the button 330, and the deformation post 342 is connected to the locking member 320.

[0059] Of course, if the manufacturing process allows, the locking part 320, the button 330, and the soft rubber elastic part 340 can also be set as an integral structure. Specifically, the support part 341 can be connected to the locking part 320 in an integral form, and the deformation column 342 can be connected to the button 330 in an integral form; or, the support part 341 can be connected to the button 330 in an integral form, and the deformation column 342 can be connected to the locking part 320 in an integral form.

[0060] Furthermore, in order to increase the contact area between the soft rubber elastic element 340 and the locking element 320, such as... Figure 5 and Figure 6 As shown, a connecting portion 343 protrudes outward from the outer periphery of the support portion 341. The connecting portion 343 connects to the surface around the opening of the through hole 410. The connecting portion 343 increases the contact area between the support portion 341 and the locking member 320, thereby improving the stability of the connection between the soft elastic member 340 and the locking member 320. Specifically, the connecting portion 343 can be formed on the support portion 341 only on one side of the base plate 321, or it can be formed on both sides of the base plate 321 to further increase the contact area between the support portion 341 and the locking member 320.

[0061] The soft rubber elastic element 340 is also used to compress when the button 330 is pressed, to ensure that the button 330 can slide a sufficient distance to disengage the air nozzle 200 from the locking member 320. Therefore, the soft rubber elastic element 340 has a support portion 341 and a deformation post 342, specifically, as Figure 3 and Figure 6 As shown, the support part 341 is groove-shaped, and one end of the deformation post 342 is inserted into the space inside the support part 341 and connected to the bottom of the groove. If the support part 341 is connected to the locking member 320, the other end of the deformation post 342 is connected to the button 330. If the support part 341 is connected to the button 330, the other end of the deformation post 342 is connected to the locking member 320.

[0062] like Figure 6 As shown, when button 330 is pressed, the distance L between button 330 and locking member 320 decreases, and deformation column 342 deforms, that is, deformation column 342 is compressed or bent, so that button 330 can move along... Figure 6 Slide the air nozzle 200 a sufficient distance in the direction indicated by the middle arrow B to disengage it from the locking member 320. Furthermore, the deformed deformation column 342 is housed within the internal space of the support portion 341. When the deformation column 342 deforms to a certain extent, the internal space of the support portion 341 is filled with the deformed deformation column 342. At this point, the outer peripheral surface of the deformation column 342 abuts against the inner sidewall of the support portion 341, and the deformation column 342 is restricted by the sidewall of the support portion 341, preventing further deformation. This effectively limits the degree of deformation of the deformation column 342, avoiding excessive deformation that could affect its service life.

[0063] In the above embodiments, by designing the soft rubber elastic element 340 and the locking element 320 or the button 330 as an integral structure, the number of parts is effectively reduced. This not only reduces the assembly difficulty of the tire pressure sensor 300 but also reduces the probability of part loss. Furthermore, when the button 330 is pressed, the deformation of the deformation post 342 ensures that the button 330 can slide a sufficient distance to disengage the air valve 200 from the locking element 320. The support portion 341 limits the deformation of the deformation post 342, preventing excessive deformation and ensuring its service life.

[0064] Furthermore, in order to design the soft elastic element 340 and the locking element 320 or the button 330 as an integral structure, the soft elastic element 340 can be made of materials such as silicone or rubber. However, the compressible volume of these materials is limited, which may affect the sliding distance of the button 330 relative to the locking element 320. Therefore, in order to ensure that the air nozzle 200 can properly disengage from the locking element 320 when the button 330 is pressed, in some embodiments, such as... Figure 3 , Figure 6 and Figure 7 As shown, Figure 7 The explosion structure of the tire pressure sensor is shown from another angle. A recess 3411 is formed on the outer surface of the support 341 on the side opposite to the deformation post 342. The support 341 is used to deform when the button 330 is pressed, and the recess 3411 is used to provide deformation space for the support 341.

[0065] Specifically, such as Figure 3 and Figure 6 As shown, when along Figure 6 When pressure is applied to button 330 in the direction indicated by arrow B, deformation column 342 will also apply pressure along the groove bottom of support portion 341. Figure 6 The pressure, indicated by the middle arrow B, is about to... Figure 6 Pressing the bottom of the groove in the direction indicated by the middle arrow B causes the bottom of the groove in the support portion 341 to bend and deform inward toward the recess 3411, thereby providing more sliding distance for the button 330. Furthermore, the deformation post 342 can be connected to the middle position of the bottom of the groove in the support portion 341, so that the pressure applied by the deformation post 342 can be evenly distributed on the bottom of the groove in the support portion 341, which helps to increase the degree of bending deformation of the bottom of the groove in the support portion 341.

[0066] In the above embodiment, by providing a recess 3411, a deformation space is provided for the support portion 341, so that when the button 330 is pressed, the bending deformation of the support portion 341 can provide more sliding distance for the button 330.

[0067] Furthermore, in order to provide more sliding distance to button 330, in some embodiments, such as Figure 6 As shown, the bottom of the groove of the support portion 341 protrudes towards the interior of the support portion 341 to form a convex hull 3412. A deformation post 342 is connected to the convex hull 3412. The convex hull 3412 is used to bend and deform towards the recess 3411 when the button 330 is pressed. The convex hull 3412 can provide more space for the formation of the recess 3411, such as... Figure 6 As shown, the top of the recess 3411 can be recessed into the support portion 341 along with the convex 3412, making the depth H1 of the recess 3411 greater, thereby providing more movement distance for the deformation column 342. Specifically, when the button 330 is pressed, the deformation column 342, under the action of force, moves towards... Figure 6 The convex 3412 is squeezed in the direction indicated by the middle arrow B, causing the convex 3412 to bend and deform toward the recess 3411, that is, changing the bending direction of the convex 3412, changing the state of the convex 3412 protruding toward the inside of the support 341 to the state of protruding toward the inside of the recess 3411. During the bending deformation of the convex 3412, the deformation column 342 can move a distance H1 in the direction indicated by the arrow B, thereby providing more sliding space for the button 330.

[0068] Furthermore, although Figure 6 The soft rubber elastic element 340 shown is inverted, connecting the support 341 to the button 330 and the deformation post 342 to the locking element 320. This arrangement reduces the number of parts while ensuring the button 330 can be pressed and reset normally. However, the pressure applied to the button 330 needs to pass through the support 341 to reach the deformation post 342, causing it to deform. In this case, in addition to the pressure acting on the deformation post 342 to cause deformation, some pressure also acts on the support 341, allowing the support 341 to move along with the button 330. Figure 6 The movement is indicated by the middle arrow B, which requires a greater force to press the button 330 so that the button 330 can slide a sufficient distance to disengage the air nozzle 200 from the locking member 320.

[0069] Therefore, to save effort, in some embodiments, such as Figure 3 and Figure 6 As shown, one end of the deformation post 342 abuts against the button 330, and the other end is connected to the bottom of the groove in the support portion 341. When the button 330 is pressed, the force applied to the button 330 can be directly transferred to the deformation post 342 through the button 330, causing the deformation post 342 to deform. In this structure, the force applied to the button 330 can be entirely transferred to the deformation post 342, causing the deformation post 342 to deform, thereby reducing the force required to press the button 330.

[0070] Furthermore, to avoid the support portion 341 obstructing the pressing of the button 330, in some embodiments, such as Figure 6 As shown, the outer wall of the support portion 341 at one end of the slot is connected to the inner wall of the through hole 410, so that the support portion 341 is located on the side of the locking member 320 away from the button 330. At this time, there are partial deformation pillars 342 between the bottom of the button 330 and the top of the locking member 320. When the button 330 is pressed, the deformation pillars 342 can be completely compressed into the interior of the support portion 341, that is, the button 330 can be pressed along the... Figure 6 The distance moved in the direction indicated by the middle arrow B is the distance L between the bottom of button 330 and the top of locking member 320, causing button 330 to move along... Figure 6 Slide the button 330 a greater distance in the direction indicated by the middle arrow B to fully unlock the air nozzle 200.

[0071] Furthermore, such as Figure 6 As shown, when button 330 is pressed, deformation post 342 applies force along the axis to support portion 341. Figure 6 The force in the direction indicated by arrow B may affect the stability of the connection between the support 341 and the locking member 320. Therefore, to ensure the stability of the connection between the support 341 and the locking member 320, in some embodiments, such as... Figure 3 and Figure 4 As shown, the sensor body 310 is provided with a mounting groove 313, and the outer wall of the support part 341 on the side away from the deformation column 342 abuts against the bottom of the mounting groove 313. The bottom of the mounting groove 313 can provide support for the walls around the support part 341. When the button 330 is pressed, the force acting on the walls around the support part 341 can be offset by the supporting force provided by the bottom of the mounting groove 313, thereby ensuring that the connection structure between the outer periphery of the support part 341 and the locking member 320 is not affected by the force applied to the support part 341 by the deformation column 342.
