Description

Technical Field

[0001] This utility model relates to the field of intelligent wheel speed sensor technology, specifically an intelligent vehicle wheel speed sensor. Background Technology

[0002] A smart wheel speed sensor is a device that measures the rotational speed of a car wheel. With the development of technology, smart wheel speed sensors are gradually incorporating intelligent functions, such as microprocessors, into their practical applications, forming more modern smart wheel speed sensors.

[0003] For example, patent CN222875663U discloses an anti-detachment automotive wheel speed sensor, including a connecting bracket. By rotating a nut onto the outer wall of a bolt to fix a fixing plate to the bearing body, a strong and stable connection force is provided, ensuring that the sensor can be firmly installed on the vehicle under various complex driving conditions. Secondly, the cooperation between the clamping plate and the fixing block allows the wires to be arranged more neatly and orderly, which helps to optimize the wiring layout inside the vehicle and reduce the potential fault risks caused by messy wiring. Furthermore, by fixing the clamping plate to the connecting bracket, the wires are prevented from loosening due to vibration, bumps, etc. during vehicle operation. In this case, when installing and fixing the automotive wheel speed sensor, although the fixing plate to the bearing body is fixed by rotating the nut onto the outer wall of the bolt to provide a stable connection force, the installation and disassembly require the use of tools to rotate the nut, which is relatively cumbersome and difficult to unlock.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing automotive intelligent wheel speed sensors. Utility Model Content

[0005] The purpose of this utility model is to provide an intelligent vehicle wheel speed sensor to solve the problem mentioned in the background art that when installing and fixing the vehicle wheel speed sensor, the fixing plate and bearing body are fixed on the outer wall of the bolt by rotating the nut. Although this can provide a stable connection force, the installation and disassembly require the use of tools to rotate the nut, which is relatively cumbersome and difficult to unlock.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent vehicle wheel speed sensor, comprising a mounting block, a mounting seat movably abutting one side of the mounting block, and an intelligent wheel speed sensor mounted on one side of the mounting seat; a ratchet is rotatably connected to one side of the mounting block, and an operating plate is rotatably connected to both ends of one side of the mounting seat via a rotating shaft, with a pawl fixedly connected to one end of the rotating shaft on one side of the operating plate; the mounting seat is internally provided with an anti-drop mechanism to prevent the intelligent wheel speed sensor from falling off.

[0007] Furthermore, the anti-drop mechanism includes two sliding rods, which are slidably connected to both sides inside the mounting base. A first tension spring is sleeved on the outer wall of the sliding rod. One end of the first tension spring is fixedly connected to the outer wall of the mounting base, and the other end of the first tension spring is fixedly connected to the outer wall of the sliding rod. A wedge block is fixedly connected to one end of the sliding rod.

[0008] Furthermore, the mounting base is fixedly connected to two ends near the wedge block, and a sliding column is slidably connected inside the mounting plate. A second tension spring is sleeved on the outer wall of the sliding column. A fixing plate is fixedly connected to one end of the second tension spring, and a locking block is fixedly connected between the two fixing plates. The other end of the second tension spring is fixedly connected to the mounting plate.

[0009] Furthermore, a spring is fixedly connected inside the mounting base, and the other end of the spring is fixedly connected to a pawl. A connecting rod is rotatably connected between the two operating plates via a rotating column.

[0010] Furthermore, the two locking blocks are positioned in opposite directions, and the interior of the mounting base has grooves that mate with the ratchet and pawl.

[0011] Furthermore, the mounting block has a groove inside that matches the wedge block and the locking block, and the other end of the slide rod is beveled.

[0012] Furthermore, the intelligent wheel speed sensor is internally equipped with a microprocessor, signal processing circuit, and communication module, and interacts with other electronic systems of the vehicle through a communication interface.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This intelligent vehicle wheel speed sensor uses a locking block that engages with a sliding rod and a wedge block. After the mounting base comes into contact with the mounting block, the locking block engages with the sensor inside the mounting block. The two locking blocks are oriented in opposite directions, which can fix the mounting base from the left and right sides, greatly improving the horizontal stability of the mounting base. The pawl engages with the ratchet, which prevents the ratchet from rotating in the opposite direction, effectively preventing the mounting base from falling off the mounting block in the vertical direction. This multi-directional and multi-angle fixing method allows the intelligent wheel speed sensor to be firmly installed on the mounting block, maintaining stability and preventing it from falling off even when the car experiences severe vibration or external impact during driving.

[0015] Furthermore, during installation, simply abut the mounting base against the mounting block and press the sliding rod to secure the locking block. Simultaneously, the pawl automatically engages with the ratchet under the action of the spring, achieving initial fixation. The entire installation process is simple and efficient. During disassembly, rotating the operating panel on one side, through the linkage of the connecting rod, can simultaneously unlock the pawl and the locking block, reducing the steps of installation and disassembly, lowering the operational difficulty, saving time and effort, and making it convenient for users to maintain and replace the intelligent wheel speed sensor.

[0016] Furthermore, the movement of the slide bar causes the wedge block to press against the locking block, thus securing the locking block. The rotation of the operating plate, linked by a connecting rod, not only unlocks the pawl but also presses the slide bar to unlock the locking block, making the entire fixing and unlocking process continuous and reliable, reducing the risk of fixing failure due to the malfunction of a single component. At the same time, the use of tension springs and springs ensures the elasticity and restoring ability of the components during movement, further improving the reliability and stability of the structure.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 Figure 4 and Figure 5 This utility model provides the following technical solution: an intelligent vehicle wheel speed sensor, including a mounting block 1, a mounting base 2 movably abutting one side of the mounting block 1, and an intelligent wheel speed sensor 3 mounted on one side of the mounting base 2; a ratchet 4 is rotatably connected to one side of the mounting block 1, and an operating plate 7 is rotatably connected to both ends of one side of the mounting base 2 via a rotating shaft, with a pawl 5 fixedly connected to one end of the rotating shaft on one side of the operating plate 7; an anti-drop mechanism is provided inside the mounting base 2 to prevent the intelligent wheel speed sensor 3 from falling off; the anti-drop mechanism includes two sliding rods 9, which are slidably connected to both sides inside the mounting base 2. A first tension spring 10 is sleeved on the outer wall of the slide rod 9. One end of the first tension spring 10 is fixedly connected to the outer wall of the mounting base 2, and the other end of the first tension spring 10 is fixedly connected to the outer wall of the slide rod 9. A wedge block 11 is fixedly connected to one end of the slide rod 9. Fixing plates are fixedly connected to both ends of the mounting base 2 near the wedge block 11. A sliding column 14 is slidably connected inside the fixing plate. A second tension spring 13 is sleeved on the outer wall of the sliding column 14. A fixing piece is fixedly connected to one end of the second tension spring 13. A locking block 12 is fixedly connected between the two fixing pieces. The other end of the second tension spring 13 is fixedly connected to the fixing plate.

[0026] When installing the intelligent wheel speed sensor 3, such as Figure 1 and Figure 2 As shown, first, the mounting base 2 abuts against the mounting block 1, then press one end of the sliding rod 9 to make the sliding rod 9 slide inside the mounting base 2, as shown. Figure 4 and Figure 5 As shown, since a first tension spring 10 is sleeved on the outer wall of the slide rod 9, one end of the first tension spring 10 is fixedly connected to the outer wall of the mounting base 2, and the other end is fixedly connected to the outer wall of the slide rod 9, when the slide rod 9 moves, it will cause one end of the first tension spring 10 to be stretched, such as... Figure 4 and Figure 5 As shown, since the other end of the slide bar 9 is fixedly connected to the wedge block 11, when the slide bar 9 moves, it will drive the wedge block 11 to move synchronously, as shown. Figure 4 and Figure 5As shown, since the mounting base 2 has fixed plates at both ends near the wedge block 11, and a sliding post 14 is slidably connected inside the fixed plate, a second tension spring 13 is sleeved on the outer wall of the sliding post 14, a fixed plate is fixedly connected to one end of the second tension spring 13, a locking block 12 is fixedly connected between the two fixed plates, and the other end of the second tension spring 13 is fixedly connected to the fixed plate, when the wedge block 11 moves, its inclined surface and protruding part on one side will gradually abut against the locking block 12, as shown. Figure 4 and Figure 5 As shown, the locking block 12 moves along the inclined surface of the wedge block 11, so the wedge block 11 will continuously squeeze the locking block 12. When the locking block 12 is squeezed, the locking block 12 will drive the fixing plate and one end of the second tension spring 13 to stretch, and drive the sliding column 14 to move synchronously. At this time, the locking block 12 will protrude out of the mounting seat 2 after being squeezed and lock into the interior of the mounting block 1, thereby fixing the mounting seat 2 and allowing the intelligent wheel speed sensor 3 to be installed on the mounting block 1. Since the two locking blocks 12 are set in opposite directions, the mounting seat 2 can be fixed from different directions, further improving the anti-drop effect.

[0027] Example 2: Please refer to Figure 3 , Figure 4 and Figure 6 Based on Embodiment 1, a spring 6 is also disclosed, the specific structure of which is as follows:

[0028] A spring 6 is fixedly connected inside the mounting base 2, and the other end of the spring 6 is fixedly connected to the pawl 5. A connecting rod 8 is rotatably connected between the two operating plates 7 through a rotating column. The two locking blocks 12 are set in opposite directions. The mounting base 2 has a groove inside that matches the ratchet 4 and the pawl 5. The mounting block 1 has a slot inside that matches the wedge block 11 and the locking block 12. The other end of the slide rod 9 is inclined. The intelligent wheel speed sensor 3 is equipped with a microprocessor, a signal processing circuit and a communication module, and interacts with other electronic systems of the car through a communication interface.

[0029] When using the auxiliary fixed mounting base 2, such as Figure 4 and Figure 6 As shown, by abutting the mounting base 2 against the mounting block 1, the groove on the mounting base 2 abuts against the ratchet 4. One end of the pawl 5 rotates around the rotation axis in the direction of the ratchet 4 under the action of the spring 6, allowing one end of the pawl 5 to abut against the ratchet 4, thus engaging the pawl 5 with the ratchet 4. At this time, the pawl 5 prevents the ratchet 4 from rotating in the opposite direction, thereby initially fixing the mounting base 2 and the mounting block 1 together, thus preventing the mounting base 2 and the mounting block 1 from falling off vertically. When removing the mounting base 2, it can be done by rotating the operating plate 7 on one side, such as... Figure 4 and Figure 6As shown, since one end of the rotating shaft on one side of the operating plate 7 is fixedly connected to the pawl 5, when one side of the operating plate 7 rotates, the pawl 5 will rotate synchronously. At this time, the pawl 5 will rotate inside the mounting base 2, as shown. Figure 4 and Figure 6 As shown, since a spring 6 is fixedly connected inside the mounting base 2, and the other end of the spring 6 is fixedly connected to the pawl 5, the pawl 5 will cause the spring 6 to be squeezed after rotation. At this time, the pawl 5 disengages from the ratchet 4. Since the two operating plates 7 are rotatably connected by a connecting rod 8 through a rotating column, when one of the operating plates 7 is rotated, as shown... Figure 4 and Figure 6 As shown, through the linkage of link 8, another control plate 7 will also rotate accordingly, as... Figure 4 and Figure 6 As shown, since one end of the slide bar 9 is inclined, when the operating plate 7 rotates, it will gradually come into contact with one end of the slide bar 9, thereby squeezing the slide bar 9. This squeezing of the slide bar 9 allows the locking block 12 to be unlocked via the slide bar 9. Therefore, by rotating the operating plate 7, the pawl 5 and the locking block 12 can be unlocked. Figure 3 As shown, the signal processing circuit inside the intelligent wheel speed sensor 3 is responsible for collecting the wheel rotation speed signal. The microprocessor can receive the signal after preliminary processing by the signal processing circuit and use the built-in algorithm to perform in-depth analysis and calculation on these signals. The main function of the communication module is to realize data interaction between the intelligent wheel speed sensor 3 and other electronic systems of the vehicle. The communication interface can be used for data transmission between the intelligent wheel speed sensor 3 and other electronic systems of the vehicle.
