Description

Technical Field

[0001] The utility model relates to the technical field of ABS wheel speed sensors, and specifically relates to a fixing and pressing device for an ABS wheel speed sensor. Background Technique

[0002] The ABS anti-lock braking system is one of the most important stability and safety systems in vehicles. It can effectively prevent the vehicle from losing control of its direction and wheel skidding during braking. The wheel speed sensor, as a sensing element of the ABS system, is generally installed at the wheel end near the wheel on the rear axle or rear shaft of the vehicle to detect the signal given by the gear ring on the half shaft assembly inside.

[0003] However, in the actual use process of existing equipment, only bolts are used to fix the sensor. When the vehicle encounters long-term vibrations during driving, the bolts may become loose, resulting in inaccurate speed sensed by the wheel speed sensor and making it difficult for the ABS to trigger at the appropriate time. In view of this, we have proposed a fixing and pressing device for an ABS wheel speed sensor. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fixing and pressing device for an ABS wheel speed sensor to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A fixing and pressing device for an ABS wheel speed sensor, including a fixing plate. The outer wall of the upper end of the fixing plate is fixedly connected with a connection port, and the outer wall of the lower end of the fixing plate is fixedly connected with a sensing port. A through fixing hole is opened on the outer wall of the fixing plate, and an internal angle bolt is penetrated and slidably connected to the inner wall of the fixing hole. A pressing assembly is arranged inside the fixing plate, and the pressing assembly includes:

[0006] A pressing rod, which is penetrated and slidably connected to the outer wall of the fixing plate. The outer wall of the lower end of the pressing rod is fixedly connected with a trapezoidal block. The outer wall of the lower end of the trapezoidal block is fixedly connected with a return spring, and the inclined surface end of the trapezoidal block is attached to an inclined block.

[0007] A sliding shell, which is fixedly connected to the end of the inclined block away from the trapezoidal block. A slider is penetrated and slidably connected to the inner wall of the sliding shell. One end of the slider close to the inner wall of the sliding shell is fixedly connected with a compression spring, and the end of the slider away from the compression spring is fixedly connected with a friction plate.

[0008] Preferably, a covering component is arranged inside the fixing plate. The covering component includes a hinged plate which is hinged to the outer wall of the pressure rod. One end of the hinged plate away from the pressure rod is hinged with a rotating shaft. A vertical rod is fixedly connected to the outer wall of the rotating shaft. One end of the vertical rod away from the rotating shaft is rotatably connected with a cover plate. A torsion spring is arranged at the connection between the cover plate and the vertical rod. When the internal angle bolt is rotated to move the pressure rod, the hinged plate can drive the vertical rod to rotate, so that the cover plate blocks the internal angle of the internal angle bolt.

[0009] Preferably, the hinged plate is arranged as a telescopic plate. The rotating shaft is rotatably connected to the inner wall of the fixing plate. A receiving groove matching the size of the vertical rod is formed in the outer wall of the fixing plate. When the internal angle bolt is away from the pressure rod, the pressure rod rotates the rotating shaft through the hinged plate, so that the vertical rod rotates into the receiving groove.

[0010] Preferably, the slope of the upper inclined surface of the inclined block is the same as that of the upper inclined surface of the trapezoidal block. The inclined surface of the inclined block fits with the inclined surface of the trapezoidal block. The inclined block slides on the outer wall of the trapezoidal block. When the pressure rod presses down, the pressure rod makes the trapezoidal block slide on the inclined block, so that the inclined block drives the sliding shell to move, and the sliding shell extends out to press against the inner wall of the vehicle rear axle, making it difficult for the fixing plate to move.

[0011] Preferably, one end of the extrusion spring away from the slider is fixedly connected to the inner wall of the sliding shell. An arc surface is arranged on the upper outer wall of the friction plate away from one end of the slider. When the sliding shell moves, the slider drives the friction plate to move, so that the friction plate contacts with the inner wall of the vehicle rear axle. The arc surface arranged on the friction plate enables the friction plate to receive greater friction force when rising.

[0012] Preferably, the size of the fixing hole is smaller than the size of the inner angle end of the internal angle bolt, and the size of the cover plate is larger than the inner angle of the internal angle bolt, so that the internal angle bolt can press the fixing plate, enabling the sensor to be fixed on the vehicle rear axle, and the cover plate can block the internal angle, making it difficult for sediment to block the internal angle bolt.

[0013] Preferably, one end of the torsion spring is fixedly connected to the outer wall of the cover plate, and the other end of the torsion spring is fixedly connected to the outer wall of the vertical rod. After the vertical rod rotates, the cover plate can be rotated so that the hexagon socket can drive the internal angle bolt to rotate. After the hexagon socket leaves, the torsion spring makes the cover plate rotate.

[0014] Compared with the prior art, the present utility model provides a fixing and pressing device for an ABS wheel speed sensor, which has the following beneficial effects:

[0015] 1. The fixed pressing device of the ABS wheel speed sensor drives the trapezoidal block to move through a pressure rod. The trapezoidal block slides on the inclined block, causing the inclined block to drive the sliding shell to extend. The friction plate can make the friction force it receives greater when rising, so that the fixing plate is fixed more firmly on the vehicle rear axle. When the vehicle is driving and encounters vibrations, the sensor will not loosen, making the sensor more firmly fixed to the vehicle and enabling the ABS to be triggered stably.

[0016] 2. The fixed pressing device of the ABS wheel speed sensor can drive the vertical rod to rotate through the hinge plate. Then, the cover plate can be rotated so that the hexagon socket can drive the socket head bolt to rotate, fixing the sensor. After the hexagon socket leaves, the torsion spring makes the cover plate block the socket of the socket head bolt, preventing the sediment raised during driving from blocking the socket and making it difficult to replace the sensor.

[0022] As Figures 1 - 4 shown, the present utility model provides a technical solution: a fixed pressing device for an ABS wheel speed sensor, including a fixing plate 1. The outer wall of the upper end of the fixing plate 1 is fixedly connected with a connection port 2, the outer wall of the lower end of the fixing plate 1 is fixedly connected with a sensing port 3. A through fixing hole 5 is opened on the outer wall of the fixing plate 1, and a socket head bolt 4 is penetrated and slidably connected to the inner wall of the fixing hole 5. A pressing assembly 6 is arranged inside the fixing plate 1, and the pressing assembly 6 includes a pressure rod 61, a trapezoidal block 62, a return spring 63, an inclined block 64, a sliding shell 65, a slide block 66, an extrusion spring 67, and a friction plate 68.

[0023] In one embodiment of the utility model, a pressure rod 61 passes through and is slidably connected to the outer wall of the fixed plate 1, a trapezoidal block 62 is fixedly connected to the outer wall of the lower end of the pressure rod 61, a return spring 63 is fixedly connected to the outer wall of the lower end of the trapezoidal block 62, and an inclined block 64 is attached to the inclined end of the trapezoidal block 62.

[0024] In one embodiment of the utility model, the sliding shell 65 is fixedly connected to the end of the inclined block 64 away from the trapezoidal block 62, and the inner wall of the sliding shell 65 is penetrated and slidably connected with a slider 66, and the end of the slider 66 close to the inner wall of the sliding shell 65 is fixedly connected to the extrusion spring 67, and the end of the slider 66 away from the extrusion spring 67 is fixedly connected to the friction plate 68.

[0025] In addition, a covering assembly 7 is provided inside the fixing plate 1, and the covering assembly 7 includes a hinged plate 71, which is hinged on the outer wall of the pressure rod 61, and the end of the hinged plate 71 away from the pressure rod 61 is hinged with a rotating shaft 72, the outer wall of the rotating shaft 72 is fixedly connected with a vertical rod 73, and the end of the vertical rod 73 away from the rotating shaft 72 is rotatably connected with a cover plate 74, and a torsion spring 75 is provided at the connection between the cover plate 74 and the vertical rod 73. When the inner angle bolt 4 is rotated to move the pressure rod 61, the hinged plate 71 can drive the vertical rod 73 to rotate, so that the cover plate 74 blocks the inner corner of the inner angle bolt 4 to prevent the mud and sand raised during driving from clogging the inner corner, making it difficult to replace the sensor.

[0026] In the embodiment of the utility model, the hinged plate 71 is configured as a telescopic plate, the rotating shaft 72 is rotatably connected to the inner wall of the fixed plate 1, and the outer wall of the fixed plate 1 is provided with a storage groove matching the size of the vertical rod 73. When the inner angle bolt 4 is away from the pressure rod 61, the pressure rod 61 rotates the rotating shaft 72 through the hinged plate 71, so that the vertical rod 73 rotates into the storage groove, so that the vertical rod 73 will not affect the rotation of the inner angle bolt 4, so that the sensor can be easily installed and disassembled.

[0027] In the embodiment of the utility model, the slope of the inclined surface on the inclined block 64 is consistent with the slope of the inclined surface on the trapezoidal block 62, and the inclined surface of the inclined block 64 fits the inclined surface of the trapezoidal block 62. The inclined block 64 slides on the outer wall of the trapezoidal block 62, so that when the pressure rod 61 is pressed down, the pressure rod 61 causes the trapezoidal block 62 to slide on the inclined block 64, so that the inclined block 64 drives the sliding shell 65 to move, and the sliding shell 65 extends out to press the inner wall of the rear axle of the vehicle, so that the fixing plate 1 is difficult to move, the sensor is fixed to the vehicle more firmly, and the ABS can be stably triggered.

[0028] In an embodiment of the present utility model, one end of the extrusion spring 67 away from the slider 66 is fixedly connected to the inner wall of the sliding housing 65. The upper outer wall of one end of the friction plate 68 away from the slider 66 is provided with an arc surface. When the sliding housing 65 moves, the slider 66 drives the friction plate 68 to move, so that the friction plate 68 contacts the inner wall of the vehicle rear axle. The arc surface provided on the friction plate 68 enables the friction plate 68 to receive a greater frictional force when rising, so that the fixing plate 1 is more firmly fixed on the vehicle rear axle, and the sensor will not become loose when the vehicle vibrates during driving.

[0029] In an embodiment of the present utility model, the size of the fixing hole 5 is smaller than the size of the inner end of the internal angle bolt 4, and the size of the cover plate 74 is larger than the internal angle of the internal angle bolt 4, so that the internal angle bolt 4 can press the fixing plate 1, so that the sensor can be fixed on the vehicle rear axle, and the cover plate 74 can block the internal angle, making it difficult for sediment to block the internal angle bolt 4, so that the sensor is easier to replace.

[0030] In an embodiment of the present utility model, one end of the torsion spring 75 is fixedly connected to the outer wall of the cover plate 74, and the other end of the torsion spring 75 is fixedly connected to the outer wall of the vertical rod 73. After the vertical rod 73 rotates, the cover plate 74 can be rotated so that the internal hexagon can drive the internal angle bolt 4 to rotate. After the internal hexagon leaves, the torsion spring 75 rotates the cover plate 74 so that the cover plate 74 can block the internal angle of the internal angle bolt 4.

[0031] In the present utility model, during use, the internal hexagon rotates the internal angle bolt 4 so that the internal angle bolt 4 can press the fixing plate 1, and the sensor is fixedly connected to the vehicle rear axle. At this time, the internal angle bolt 4 can drive the pressure rod 61 to press down, so that the pressure rod 61 drives the trapezoidal block 62 to move. At this time, the trapezoidal block 62 slides on the inclined block 64, and then the inclined block 64 drives the sliding housing 65 to extend. The arc surface provided on the friction plate 68 enables the friction plate 68 to receive a greater frictional force when rising, so that the fixing plate 1 is more firmly fixed on the vehicle rear axle, and the sensor will not become loose when the vehicle vibrates during driving, making the connection between the sensor and the vehicle more firm, enabling the ABS to be triggered stably. The articulated plate 71 can drive the vertical rod 73 to rotate, and then the cover plate 74 can be rotated so that the internal hexagon can drive the internal angle bolt 4 to rotate, so that the sensor can be fixed. After the internal hexagon leaves, the torsion spring 75 rotates the cover plate 74, so that the cover plate 74 can block the internal angle of the internal angle bolt 4, preventing the sediment raised during driving from blocking the internal angle and making it difficult to replace the sensor.

[0032] The above has generally described the present utility model in detail, but based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
