Description

A quick-release wheel speed sensor Technical Field

[0001] This invention relates to the field of wheel speed sensors, and more specifically, to a wheel speed sensor that can be quickly installed and removed. Background Technology

[0002] Wheel speed sensors are used to measure the rotational speed of a car's wheels. Wheel speed information is essential for modern vehicles, as it is required by vehicle dynamic control systems, electronic stability programs, anti-lock braking systems, and automatic transmission control systems. Therefore, wheel speed sensors are among the most critical sensors in modern automobiles.

[0003] A wheel speed sensor generally consists of a sensor housing, a sensing component inside the housing, and fastening bolts connecting the sensor housing to the vehicle for assembly. Automotive wheel speed sensors are typically installed on the wheel hub of each wheel, at the position of the front wheel brake disc. Installation is accomplished by securing the wheel speed sensor to the vehicle body using the fastening bolts. However, the following defects have been observed during actual installation and subsequent maintenance of wheel speed sensors:

[0004] 1. Due to the special installation position of the wheel speed sensor, its installation space is affected by the structure of the vehicle frame, wheel hub and its inner brake components, resulting in a relatively limited operating space. In addition, since the installation angle of the wheel speed sensor is relatively fixed, in the subsequent maintenance of the car, it is necessary to use specific disassembly tools (such as an Allen wrench) to remove the fastening bolts on it before the wheel speed sensor can be disassembled.

[0005] 2. Similarly, during the installation after maintenance, the operator also needs to pass the hex bolt through the sensor housing on the wheel speed sensor assembly and align one end with the mounting hole, and then use a tool to tighten it with a knob. However, the hex bolt is very prone to tilting or misalignment during the initial rotation, which can easily cause assembly difficulties.

[0006] Therefore, we made improvements and proposed a wheel speed sensor that can be quickly installed and removed. Summary of the Invention

[0007] The purpose of this invention is to provide a wheel speed sensor that can be quickly installed and disassembled. By setting up a contacting component and a connecting mechanism, it solves the problem that the installation and subsequent disassembly of traditional wheel speed sensors are inconvenient.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0009] A wheel speed sensor that can be quickly disassembled and assembled includes a sensor housing, a sensing end located inside one end of the sensor housing, and a cable housing connector located at the other end inside the sensor housing. It also includes a fastening bolt and a housing connector fixed to the surface of the sensor housing. A connecting mechanism that mates with the fastening bolt is fixedly connected to one side of the housing connector.

[0010] An abutting component disposed on the surface of a fastening bolt, the abutting component comprising a lower abutting mechanism, an upper abutting mechanism, and a top fastening cap;

[0011] The connecting mechanism includes a connecting plate fixed to one side of the housing connecting seat, an arc-shaped groove opened on one side of the connecting plate for fastening bolts to pass through, and an internal slot opened on the inner wall of the arc-shaped groove.

[0012] The top and bottom of the connecting plate are respectively formed with the housing connecting seat by an upper mating groove and a lower mating groove, and the center of the upper mating groove, the lower mating groove and the arc groove are all coaxially mated with the center of the connecting plate.

[0013] As a preferred technical solution of this application, the lower abutment mechanism includes a lower base plate, a connecting block fixed to the surface of the lower base plate, and a buckle assembly disposed on the outside of the connecting block;

[0014] The buckle assembly corresponds to and is adapted to the internal slot of the arc-shaped groove, while the connecting block corresponds to the arc-shaped groove and forms a snap-fit ​​engagement with the connecting plate through the buckle assembly.

[0015] As a preferred technical solution of this application, the upper abutment mechanism includes an upper base plate, a sliding plate rotatably disposed on the top of the upper base plate, and an embedded protective ring coaxially fixedly engaged with the top of the sliding plate.

[0016] As a preferred technical solution of this application, the bottom of the top fastening cap is formed with an embedding groove that cooperates with the embedded protective ring, and the interior of the top fastening cap is provided with a built-in groove for the fastening bolt to be inserted.

[0017] As a preferred technical solution of this application, the top of the lower plate and the bottom of the upper plate are respectively provided with a first anti-slip protrusion and a second anti-slip protrusion;

[0018] The top and bottom of the connecting plate have anti-slip inner grooves that correspond to and fit the first and second anti-slip protrusions.

[0019] As a preferred technical solution of this application, the buckle assembly includes a driving component disposed inside the connecting block and a buckle that cooperates with the driving component.

[0020] As a preferred technical solution of this application, the buckle includes a movable cavity formed on the outside of the connecting block, a swing arm movably assembled on both sides inside the movable cavity via a pin, and a convex surface formed on the outside of the swing arm and adapted to the internal slot.

[0021] The ends of the two swing arms in the same movable cavity that are away from the convex surface are both equipped with adjusting plates via pins, and the two adjusting plates are connected to a transmission pull plate via pins.

[0022] As a preferred technical solution of this application, the driving component includes a trapezoidal block slidably disposed inside the connecting block, a sliding block that abuts against and slides at the bottom of the trapezoidal block and corresponds to the transmission pull plates on the four buckles, the sliding block being fixedly connected to the end of the corresponding transmission pull plate away from the adjusting plate, a spring being fixedly connected to the bottom of the trapezoidal block, and one end of the spring being fixedly connected to the inner bottom wall of the connecting block.

[0023] As a preferred technical solution of this application, the top of the trapezoidal block extends to the outside of the connecting block to form a transmission pressure column, and a transmission pressure plate is fixedly connected to the top of the transmission pressure column. The bottom of the connecting plate is provided with a positioning groove corresponding to the transmission pressure plate.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] In the scheme of this application:

[0026] 1. Through the set connection mechanism, after the fastening bolt is rotated several times to release the resistance to the connecting plate, the upper resistance mechanism releases the resistance to the drive component, so that the buckle will not limit the connection plate. Thus, the connecting plate and the sensor housing connected to it can be taken out through the arc groove on it, realizing the quick disassembly of the sensing component. At this time, the fastening bolt is not completely removed, which makes it more convenient for the subsequent quick assembly of the sensor housing and its uploading components. This solves the problem that wheel speed sensors are not easy to disassemble in the existing technology.

[0027] 2. By using the set connection mechanism, the connecting plate on the sensor housing is directly fitted onto the surface of the fastening bolt through the arc groove, and the connecting block is moved to engage with the corresponding arc groove. Then the fastening bolt is finally tightened, thus quickly realizing the assembly work after the wheel speed sensor is overhauled. This solves the problem in the prior art that when the wheel speed sensor is disassembled and then installed, the internal hex bolts are not easy to align and the installation is prone to misalignment.

[0028] 3. Through the connection mechanism and abutment components, the upper and lower abutment components are tightly fitted to the surface of the connecting plate, allowing the drive mechanism to unfold the latch within the internal slot, thus locking the connecting plate and preventing it from falling off during installation and use. Simultaneously, the upper and lower mating grooves, along with the fastening bolts, ensure the upper and lower abutment mechanisms are securely fastened, forming a more stable whole and preventing relative slippage or displacement. This facilitates more stable installation and use of the wheel speed sensor.

[0029] 4. Through the upper and lower contact mechanisms, during the tightening process of the fastening bolts to secure the connecting plate, the relative sliding between the upper plate seat and the sliding plate prevents the top fastening cap from simultaneously rotating the upper plate seat during tightening. This effectively improves the installation accuracy of the wheel speed sensor. At the same time, placing the connecting plate between the lower and upper plates provides effective protection, reducing the risk of breakage and detachment from the housing connecting plate due to wear. Furthermore, it facilitates the replacement of the upper and lower contact mechanisms, which are more prone to wear, without affecting the overall use of the wheel speed sensor.

In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0052] Please refer to Figures 1 to 10. The present invention provides a technical solution: a wheel speed sensor that can be quickly disassembled and assembled, including a sensor housing 10, a sensing end 101 disposed inside one end of the sensor housing 10, and a cable housing connector 102 disposed at the other end of the sensor housing 10; it also includes a fastening bolt 104 and a housing connector 103 fixed to the surface of the sensor housing 10, and a connecting mechanism 20 that cooperates with the fastening bolt 104 is fixedly connected to one side of the housing connector 103;

[0053] An abutting component is provided on the surface of the fastening bolt 104, the abutting component includes a lower abutting mechanism 30, an upper abutting mechanism 40 and a top fastening cap 105;

[0054] The sensing end 101 includes a permanent magnet, a sensing coil, and a polar shaft (not shown in the figure) protruding from the end of the sensor housing 10 inside the sensor housing 10. The sensor housing 10, sensing end 101, cable connector 102, connecting mechanism 20, and contacting component together form the wheel speed sensor. During installation, the wheel speed sensor connects the cable housing connector 102 to the external data cable, aligns the polar shaft on the sensing end 101 with the gear ring on the car wheel axle, and connects it to the corresponding component on the bottom of the car through the connecting mechanism and contacting component. During the car's operation, the wheel speed is detected by the engagement between the rotating gear ring and the sensing end 101.

[0055] The connecting mechanism 20 includes a connecting plate 201 fixed to one side of the housing connecting seat 103, an arc-shaped groove 202 opened on one side of the connecting plate 201 and allowing the fastening bolt 104 to pass through, and an internal slot 203 opened on the inner wall of the arc-shaped groove 202. The connecting plate 201 can be sleeved on the surface of the fastening bolt 104 through the arc-shaped groove 202, and the connecting plate 201 can be removed from the surface of the fastening bolt 104 through the arc-shaped groove 202, thereby facilitating the removal of the sensor housing and its sensing components.

[0056] The top and bottom of the connecting plate 201 are respectively formed with the housing connecting seat 103 to form an upper mating groove 204 and a lower mating groove 205, and the centers of the upper mating groove 204, the lower mating groove 205 and the arc groove 202 are coaxially mated with the center of the connecting plate 201.

[0057] The lower contact mechanism 30 includes a lower base plate 301, a connecting block 302 fixed to the surface of the lower base plate 301, and a latching assembly 303 disposed on the outside of the connecting block 302;

[0058] Among them, the snap fastener 303 corresponds to and is adapted to the inner slot 203 of the inner wall of the arc groove 202, and the connecting block 302 corresponds to the arc groove 202 and forms a snap-fit ​​engagement with the connecting plate 201 through the snap fastener 303;

[0059] The upper contact mechanism 40 includes an upper base plate 401, a sliding plate 402 rotatably disposed on the top of the upper base plate 401, and an embedded protective ring 403 coaxially fixedly engaged with the top of the sliding plate 402. The lower plate base 301 and the upper plate base 401 both have grooves formed at their centers for fastening bolts 104 through slots.

[0060] The bottom of the top fastening cap 105 has an embedded groove that mates with the embedded protective ring 403, and the inside of the top fastening cap 105 has an internal groove for the fastening bolt 104 to be inserted. With the embedded groove and the internal groove, after the fastening bolt 104 is inserted into the inside of the top fastening cap 105, the upper plate seat 401 can be integrated with the top fastening cap 105 through the engagement of the embedded protective ring 403. This makes it difficult for dust and debris from the outside to fall into the inside through the gap between the top fastening cap 105 and the upper plate seat 401. At the same time, it is also beneficial for the top fastening cap 105 to rotate synchronously with the upper plate body 401 through the embedded protective ring 403 during the rotation process, which is conducive to the fastening operation.

[0061] Specifically, when it is necessary to disassemble the sensor housing and the sensing components inside the wheel speed sensor, rotate the fastening bolt 104 to move it away from the upper contacting member 40. When the upper contacting member 40 and the lower contacting member 30 release their contact limit on the connecting plate 201, the upper contacting member 40 also releases the drive of the drive member 310, causing the buckle 302 to engage with the locking of the internal slot 203, so that the connecting plate 201 and the lower plate 301 can be separated from each other. After they are separated, the housing connecting seat 103 and the sensor housing 10 on it can be removed through the arc groove 202, which facilitates the maintenance operation of the staff.

[0062] Compared to the traditional method of simply using hex bolts to fasten the sensing components, the above operation avoids the need to completely disassemble the hex bolts in order to remove the sensing components for maintenance. This reduces the time required to use disassembly tools, saves operational efficiency, and facilitates subsequent installation processes such as aligning the hex bolts with the mounting holes again, thus improving the work efficiency of the staff.

[0063] The top of the lower plate 301 and the bottom of the upper plate 401 are respectively provided with a first anti-slip protrusion 304 and a second anti-slip protrusion 404. There are several first anti-slip protrusions 304 and several second anti-slip protrusions 404. The several first anti-slip protrusions 304 are evenly distributed on the surface of the lower plate 301 in a ring array. Similarly, the several second anti-slip protrusions 404 are evenly distributed on the surface of the upper plate 401 in a ring array. The positions of the second anti-slip protrusions 404 distributed on the upper plate 401 do not include the area corresponding to the arc groove 202. The positions of the first anti-slip protrusions 304 distributed on the lower plate 301 do not include the area of ​​the connecting block 302.

[0064] The top and bottom of the connecting plate 201 are formed with anti-slip inner grooves 206 that correspond to and fit the first anti-slip protrusion 304 and the second anti-slip protrusion 404. Several first anti-slip protrusions 304 and second anti-slip protrusions 404 are staggered in the same vertical direction, so that when they are engaged with the corresponding anti-slip inner grooves 206, the force is more uniform and the anti-slip effect is better.

[0065] When the upper plate seat 401 and the lower plate seat 301 are tightly attached to the surface of the connecting plate 201, the first anti-slip protrusion 304 and the second anti-slip protrusion 404 can both cooperate with the anti-slip inner groove 206, so that the upper plate seat 401 and the lower plate seat 301, after being tightened, together with the connecting plate 201, form an integral whole, making it difficult for the upper plate seat 401 and the lower plate seat 301 to be relatively displaced from the connecting plate 201 during subsequent use;

[0066] Furthermore, when the upper plate seat 401 and the lower plate seat 301 are in close contact with each other on the surface of the connecting plate 201, they are respectively placed inside the corresponding upper mating groove 204 and lower mating groove 205, which makes the contact area between the connecting plate 201 and the upper plate seat 401 and the lower plate seat 301 better, and also plays a good role in preventing vertical displacement in the vertical direction, which is conducive to the more stable use of the sensor.

[0067] Meanwhile, the cooperation between the upper plate seat 401 and the lower plate seat 301 can effectively protect the connecting plate 201. Since the lower plate seat 301 directly contacts the surface of the vehicle after assembly, it avoids direct contact between the connecting plate 201 and the vehicle, which is beneficial to the protection of the connecting plate 201 and makes its connection strength with the housing connecting seat 103 better. At the same time, the contact between the lower plate seat 301 and the vehicle increases the contact area between the sensor fastening position and the measurement, making it less likely to slip relative to each other after installation. In addition, the combination of the first anti-slip protrusion 304 and the second anti-slip protrusion 404 together forms an anti-slip effect for the sensor as a whole, reducing the occurrence of subsequent offset.

[0068] The latching assembly 303 includes a driving component 310 disposed inside the connecting block 302 and a latch 320 that cooperates with the driving component 310;

[0069] The latch 320 includes a movable cavity 321 formed on the outside of the connecting block 302, a swing arm 322 movably mounted on both sides inside the movable cavity 321 via a pin, and a convex surface 323 formed on the outside of the swing arm 322 and adapted to the internal slot 203, as shown in Figure 4. The internal slot 203 is adapted to the swing arm 322 and its convex surface 323. The swing arm 322 can swing in the corresponding movable cavity 321. In the initial state, the two swing arms 322 in the same movable cavity 321 are in a close-to-each-other state. At this time, the lower plate seat 3 When the upper plate seat 401 is in close contact with the connecting plate 201, the swing arm 322 will not obstruct its movement. However, when the upper plate seat 401 is in close contact with the surface of the connecting plate 201, the two swing arms 322 in the same movable cavity 321 open up to each other and press against the inner wall of the internal slot 203 through the convex surface 323. At this time, the connecting plate 201 cannot be directly removed parallel to the surface of the fastening bolt 104. Due to the upper and lower positions and the limitation by the upper plate seat 401 and the lower plate seat 301, the connecting plate 201 is in a fixed state.

[0070] The ends of the two swing arms 322 in the same movable cavity 321 that are away from the convex surface 323 are both movably fitted with adjusting plates 324 by means of pins, and the two adjusting plates 324 are movably connected to the transmission pull plate 325 by means of pins.

[0071] The driving component 310 includes a trapezoidal block 311 slidably disposed inside the connecting block 302, and a sliding block 312 that abuts against and slides at the bottom of the trapezoidal block 311 and corresponds to the transmission pull plates 325 on the four buckles 320. The sliding block 312 is fixedly connected to the end of the corresponding transmission pull plate 325 away from the adjusting plate 324. The transmission pull plate 325 is partially slidably engaged with the connecting block 302. A spring is fixedly connected to the bottom of the trapezoidal block 311, and one end of the spring is fixedly connected to the inner bottom wall of the connecting block 302.

[0072] The top of the trapezoidal block 311 extends to the outside of the connecting block 302 to form a transmission pressure column 313, and the top of the transmission pressure column 313 is fixedly connected to a transmission pressure plate 314. The bottom of the connecting plate 201 is provided with a positioning groove 315 corresponding to the transmission pressure plate 314.

[0073] Specifically, when the upper plate 401 is brought closer to the connecting plate 201 by the tightening force of the fastening bolt 104, the positioning groove 315 on the upper plate 401 is aligned with the transmission pressure plate 314 and pressed down. After being subjected to pressure, the transmission pressure plate 314 synchronously drives the trapezoidal block 311 to slide closer to the interior of the connecting plate 201, causing the connecting plate 201 to compress the bottom sliding block 312, causing multiple sliding blocks 312 to slide. Through the sliding of the sliding blocks 312, the transmission pull plate 325 connected to it is activated. The adjustment plate 324 is moved, and the movement of the adjustment plate 324 can unfold the two swing arms 322 in the same movable cavity 321. When the convex surface on the swing arm 322 unfolds into the interior slot 203, the outer side of the swing arm 322 is in close contact with the edge of the inner wall of the movable cavity 321 and is in a tight state. At this time, the buckle 320 completes the connection and engagement with the connecting plate 201. At the same time, the upper plate seat 401 is in close contact with the surface of the connecting plate 201 and forms a tight fit with the lower plate seat 301.

[0074] Meanwhile, when the sensing component is disassembled by loosening or tightening the fastening bolt 104, the upper plate seat 401 does not apply the resistance force of the transmission pressure plate 314 on the connecting block 302 due to the loosening or tightening of the fastening bolt 104. At this time, the trapezoidal block 311 can be moved upward and reset by the elastic force of the spring, contacting the limit of the outer sliding block 312. At this time, pulling the connecting plate 201 upward can contact the swing arm 322 through the action of the internal slot 203, so that the two swing arms 322 in the same active cavity 321 can approach each other to form the reset of the transmission pull plate 325 and the sliding block 312 on it, which is convenient for subsequent re-fitting.

[0075] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.
