Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to an end cap structure, a wheel speed sensor, and a vehicle. Background Technology

[0002] Wheel speed sensors are key components in automotive electronic systems, primarily used to monitor wheel rotation speed in real time and transmit the data to vehicle control units (such as ABS and ESP systems) to ensure driving safety. Wheel speed sensors are typically mounted near the wheel bearings or wheel hubs, maintaining a certain air gap with the wheel toothed ring to ensure signal accuracy.

[0003] In existing technologies, when wheel speed sensors are paired and installed with mounting holes on the vehicle body, a fastening connection is required using bolts, bushings, etc., which makes the installation process complex and costly. Utility Model Content

[0004] The purpose of this invention is to solve the problem of complex and costly installation of existing wheel speed sensors. This invention provides an end cap structure, a wheel speed sensor, and a vehicle, enabling efficient and convenient installation of the wheel speed sensor on the vehicle body without the need for bolts, bushings, or other connecting parts, thus reducing manufacturing costs.

[0005] To solve the above-mentioned technical problems, an embodiment of this utility model discloses an end cap structure, comprising:

[0006] The body includes mounting holes for mounting wheel speed sensors;

[0007] A first connecting portion is disposed around the mounting hole;

[0008] Multiple snap-fit ​​parts are spaced apart from the first connecting part and are used to snap onto the housing of the wheel speed sensor;

[0009] The second connecting part is located on the side of the body opposite to the first connecting part and is used for connecting with a vehicle.

[0010] By adopting the above technical solution, a rapid and stable connection between the end cap structure, the wheel speed sensor, and the vehicle can be achieved through the synergistic action of the main body, the first connecting part, multiple snap-fit ​​parts, and the second connecting part. The first connecting part is arranged around the mounting hole and cooperates with the snap-fit ​​parts to provide a uniform force distribution, avoiding the stress concentration problem caused by traditional bolt tightening. During installation, simply align the wheel speed sensor with the mounting hole, allowing the snap-fit ​​parts to snap into the wheel speed sensor housing. Then, the second connecting part allows both the end cap structure and the wheel speed sensor to be mounted on the vehicle body. Without the need for bolts, bushings, or other connecting parts, the wheel speed sensor can be efficiently and conveniently installed on the vehicle body, reducing the number of parts and process steps during installation and effectively reducing costs.

[0011] According to another specific embodiment of the present invention, an end cap structure is disclosed, including a stop portion, the stop portion extending along a first direction and disposed on the first connecting portion, and a stop portion being disposed between two adjacent snap-fit ​​portions.

[0012] By adopting the above technical solution, the guiding and limiting functions of the end cover structure can be enhanced through the coordinated arrangement of the stop and the snap-fit. The stop extends along the first direction and is located between adjacent snap-fits, working in conjunction with the snap-fits to not only guide the sensor housing into accurate position during installation, but also prevent the sensor from rotating or shifting during operation, thereby improving sealing and connection stability and reducing wear problems caused by micro-movements.

[0013] According to another specific embodiment of the present invention, an end cap structure is disclosed, wherein the spacing between two adjacent snap-fit ​​portions is the same.

[0014] By adopting the above technical solution, the spacing between adjacent snap-fit ​​parts can be set to be the same, and the uniform distribution of multiple snap-fit ​​parts can be coordinated to achieve symmetrical clamping force on the sensor housing, which can avoid local stress concentration and improve sealing uniformity.

[0015] According to another specific embodiment of the present invention, an end cap structure is disclosed, which is made of metal material.

[0016] The above technical solution uses a metal cap structure, which has good mechanical strength and corrosion resistance, avoiding the creep or aging problems that may occur with plastic materials. At the same time, the thermal conductivity of metal can also help dissipate heat, improving the reliability of the sensor in high-temperature environments.

[0017] According to another specific embodiment of the present invention, an end cap structure is disclosed, wherein the first connecting part is an annular protrusion, and the first connecting part protrudes from the body along a first direction.

[0018] According to another specific embodiment of the present invention, an end cap structure is disclosed, wherein along the first direction, the first connecting portion is provided with six snap-fit ​​portions at intervals on the side away from the body.

[0019] By adopting the above technical solution, 360-degree uniform snap-fit ​​is achieved, which not only improves the installation speed but also enhances the resistance to torsional loads and avoids fatigue failure caused by a few snap-fit ​​points, thereby improving the overall durability of the structure.

[0020] This utility model also discloses a wheel speed sensor, which includes:

[0021] The end cap structure in any of the above embodiments;

[0022] The housing passes through the mounting hole of the end cap structure and is connected to the snap-fit ​​portion of the end cap structure.

[0023] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a wheel speed sensor, wherein the housing includes a snap-fit ​​groove that extends circumferentially along the housing, and one end of the snap-fit ​​portion is disposed in the snap-fit ​​groove.

[0024] By adopting the above technical solution, precise snap-fit ​​positioning can be achieved by setting a snap-fit ​​groove on the housing to cooperate with the snap-fit ​​part.

[0025] According to another specific embodiment of the present invention, a wheel speed sensor is disclosed. The housing includes a sealing groove and a sealing ring. Along a first direction, the sealing groove and the snap-fit ​​groove are spaced apart. The sealing ring is disposed in the sealing groove and abuts against the inner wall of the first connecting part.

[0026] By adopting the above technical solution, a sealing groove and a sealing ring can be provided in the shell, which work together with the inner wall of the first connecting part to form a multiple sealing barrier. The synergistic sealing between the sealing ring and the inner wall of the first connecting part enhances dustproof and waterproof performance.

[0027] The present invention also discloses a vehicle, which includes at least the wheel speed sensor described in any of the above embodiments. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0040] In some embodiments, see Figure 1 , Figure 2 This application provides a vehicle, including a wheel speed sensor and a vehicle body. The wheel speed sensor is disposed near the wheel bearing or wheel hub of the vehicle body. The wheel speed sensor includes an end cap structure 10 and a housing 20. The housing 20 passes through a mounting hole 111 in the end cap structure 10 and is connected to a snap-fit ​​portion 13 of the end cap structure 10. Exemplarily, the housing 20 includes a limiting portion 21 that can abut against the end cap structure 10.

[0041] In some embodiments, see Figure 2 , Figure 3 , Figure 4 The end cap structure 10 includes a body 11, a first connecting portion 12, a snap-fit ​​portion 13, and a second connecting portion 14. The body 11 includes a mounting hole 111 through which a wheel speed sensor passes, and the first connecting portion 12 surrounds the mounting hole 111. Exemplarily, the body 11 includes a top 112 and a side portion 113, which together form a cavity 114 with an opening 1141. The mounting hole 111 is located in the top 112, and within the cavity 114, a limiting portion 21 abuts against the top 112. Exemplarily, the first connecting portion 12, the second connecting portion 14, and the side portion 113 are all annular protrusions. Along the first direction Z, the first connecting portion 12 and the second connecting portion 14 protrude from both sides of the body 11, with the first connecting portion 12 protruding from the top 112 and the second connecting portion 14 protruding from the side portion 113. It is understood that the shapes of the first connecting portion 12 and the side portion 113 are not limited in the embodiments of this application; for example, they may also be cubic or the like.

[0042] For example, see Figure 2 , Figure 3 , Figure 4 Along the first direction Z, a second connecting portion 14 is disposed on the side of the main body 11 facing away from the first connecting portion 12, for connecting with the vehicle. The first connecting portion 12, on the side away from the top 112, is provided with six locking portions 13 spaced apart for locking onto the housing 20 of the wheel speed sensor. Exemplarily, a protrusion 1131 is provided between the side portion 113 and the second connecting portion 14. The protrusion 1131 is annular and protrudes along the second direction Y. In some embodiments, the second connecting portion 14 is also annular and can be inserted into the wheel hub of the vehicle. It is understood that the shapes of the second connecting portion 14 and the protrusion 1131 are not limited in this application embodiment, nor is the number of locking portions 13 limited; for example, it can be 2, 3, 4, 5, 7, etc.

[0043] By adopting the above technical solution, a fast and stable connection between the end cap structure 10 and the wheel speed sensor and the vehicle can be achieved through the synergistic action of the main body 11, the first connecting part 12, multiple snap-fit ​​parts 13, and the second connecting part 14. The first connecting part 12 is arranged around the mounting hole 111 and cooperates with the snap-fit ​​part 13 to provide a uniform force distribution, avoiding the stress concentration problem caused by traditional bolt tightening. During installation, the wheel speed sensor only needs to be aligned with the mounting hole 111, so that the snap-fit ​​part 13 snaps into the housing 20 of the wheel speed sensor. Then, the end cap structure 10 and the wheel speed sensor are both mounted on the vehicle body through the second connecting part 14. Without the participation of bolts, bushings, or other connecting parts, the wheel speed sensor can be installed on the vehicle body efficiently and conveniently, reducing the number of parts and process steps during installation and effectively reducing costs.

[0044] In some embodiments, see Figure 2 , Figure 3 , Figure 4 The end cap structure 10 includes a stop portion 15, which extends along the first direction Z and is disposed on the first connecting portion 12. A stop portion 15 is provided between two adjacent snap-fit ​​portions 13. Exemplarily, the stop portion 15 is a protrusion extending vertically along the first direction Z. The stop portion 15 is not directly connected to the housing 20. The stop portion 15 extends along the first direction Z and is disposed between adjacent snap-fit ​​portions 13, working in conjunction with the snap-fit ​​portions 13. It not only guides the sensor housing 20 to be accurately positioned during installation, but also prevents the sensor from rotating or shifting during operation, thereby improving sealing and connection stability and reducing wear problems caused by micro-movements.

[0045] In some embodiments, see Figure 3 , Figure 4 , Figure 5 Along the first direction Z, the latching portion 13 includes a first end 131 and a second end 132. The first end 131 protrudes from the first connecting portion 12, and the second end 132 (i.e., one end of the aforementioned latching portion 13) is inclined and connected to the housing 20. For example, the spacing between adjacent latching portions 13 is the same. The coordinated and uniform distribution of multiple latching portions 13 achieves a symmetrical clamping force on the sensor housing 20, avoiding localized stress concentration and improving sealing uniformity.

[0046] In some embodiments, the end cap structure 10 is made of a metallic material. Exemplarily, the body 11, the first connecting portion 12, the snap-fit ​​portion 13, and the second connecting portion 14 of the end cap structure 10 are all made of a metallic material. This application does not limit the metallic material; for example, it can be iron, copper, or an alloy. The end cap structure 10, being made of a metallic material, possesses good mechanical strength and corrosion resistance, avoiding the creep or aging problems that may occur with plastic materials. Furthermore, the thermal conductivity of metal helps dissipate heat, improving the reliability of the sensor in high-temperature environments.

[0047] Furthermore, in some embodiments, the end cap structure 10 may also be made of other materials such as polyethylene, and this application embodiment does not limit this.

[0048] In some embodiments, see Figure 4 , Figure 5 , Figure 6 The housing 20 includes a snap-fit ​​groove 22, and one end of the snap-fit ​​portion 13 is disposed in the snap-fit ​​groove 22. Exemplarily, the snap-fit ​​groove 22 extends along the circumferential direction R of the housing 20, and the second end 132 of each snap-fit ​​portion 13 can be snapped into the snap-fit ​​groove 22 and abut against the groove wall 221 of the snap-fit ​​groove 22.

[0049] In some embodiments, the housing 20 includes a sealing groove 23 and a sealing ring 24. Along the first direction Z, the sealing groove 23 is spaced apart from the snap-fit ​​groove 22. The sealing ring 24 is disposed in the sealing groove 23 and abuts against the inner wall 121 of the first connecting portion 12. Exemplarily, both the sealing groove 23 and the sealing ring 24 extend along the circumferential direction R of the housing 20.

[0050] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
