Description

Technical Field

[0001] This utility model relates to the field of automotive electronic control technology, specifically to a high-temperature resistant ABS sensor. Background Technology

[0002] The function of ABS sensors (anti-lock braking system sensors) is to monitor the wheel speed in real time and transmit this data to the vehicle's ABS control unit. By analyzing this data, the ABS system can determine whether the wheels are about to lock up and automatically adjust the braking pressure if necessary to prevent the wheels from stopping completely, thereby maintaining the vehicle's stability and handling during emergency braking, effectively shortening the braking distance and reducing the risk of accidents.

[0003] CN205374496U discloses an ABS wheel speed sensor, including a sensor body and a wiring harness assembly. The sensor body includes a frame assembly and an injection-molded body. The frame assembly includes a frame body, magnets, pole pieces, and lead wires. The magnets and pole pieces are inserted into the frame body without gaps. The two ends of the coil are soldered to the lead wires. The injection-molded body is injection-molded onto the outside of the frame assembly. The wiring harness assembly includes a cable harness, a cable harness protective sleeve, and a connector. One end of the cable harness is connected to the connector, and the other end is spot-welded to the wiring hole of the circuit board. The cable harness protective sleeve covers the outside of the wires and has a long service life. However, this technology does not have a fixed structure for the wiring harness assembly. During vehicle transportation and driving, the turning of the vehicle can cause the wiring harness assembly to shake violently, causing the sensor to become loose from the vehicle. Therefore, this technology still has some room for improvement. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a high-temperature resistant ABS sensor to address the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant ABS sensor, comprising a sensor end, a wiring harness assembly, and a connector, wherein the connector and the sensor end are respectively disposed at both ends of the wiring harness assembly, characterized in that: the wiring harness assembly includes an outer shell, the outer shell is fitted with a plurality of retainers, the retainers include a connecting block and an abutment block fixedly disposed at the bottom of the connecting block, the abutment block abuts against the outer periphery of the vehicle, and the bottom of the abutment block is provided with a snap-fit ​​structure for engaging with the vehicle.

[0006] By adopting the above technical solution, the fastener, through the connecting block and the abutment block, enables the wiring harness assembly to be tightly and stably fixed in a specific position on the vehicle, effectively reducing sensor malfunctions caused by shaking or displacement during vehicle operation. The abutment block abuts against the outer periphery of the vehicle, which not only increases the stability of the installation but also effectively disperses vibration and impact forces during vehicle operation, further protecting the internal wiring harness. The snap-fit ​​structure at the bottom of the abutment block improves the working stability and reliability of the ABS sensor and extends its service life.

[0007] The aforementioned high-temperature resistant ABS sensor can be further configured as follows: the snap-fit ​​structure includes a connecting rod disposed at the bottom of the abutment block, snap-fit ​​blocks are disposed on both sides of the connecting rod, the snap-fit ​​blocks extend toward the abutment block to make the snap-fit ​​blocks V-shaped, a movable groove is formed between the snap-fit ​​blocks and the connecting rod to give the snap-fit ​​blocks a range of motion, the snap-fit ​​blocks are made of elastic material, and a snap-fit ​​protrusion is provided at one end of the snap-fit ​​block facing the abutment block, the snap-fit ​​protrusion being stepped downwards from the end of the snap-fit ​​block facing the abutment block.

[0008] Using the above technical solution, the V-shaped locking blocks on both sides of the connecting rod can provide a larger contact area and stronger gripping force, ensuring the stability of the connection between the wiring harness assembly and the vehicle. The movable groove provides the necessary range of motion for the locking blocks, allowing them to deform appropriately for locking when subjected to external force, further enhancing the reliability of the connection. The stepped locking protrusions on the end of the locking blocks facing the abutment block not only increase the friction between the locking blocks and the vehicle, preventing the connection from loosening, but also effectively guide the force distribution during the locking process through their downward stepped design, making the entire locking operation smoother and more stable.

[0009] The aforementioned high-temperature resistant ABS sensor can be further configured such that: limiting plates are provided on both sides of the connecting rod, and a limiting groove for limiting the connecting rod is formed between the limiting plates and the connecting rod.

[0010] By adopting the above technical solution, the limiting plates added to both sides of the connecting rod and the limiting groove formed between them enhance the stability and reliability of the snap-fit ​​structure, effectively limit the excessive lateral movement of the connecting rod, ensure the precise positioning and stable connection of the connecting rod during the snap-fit ​​process, prevent the connection from loosening or shifting due to vibration and impact during vehicle operation, and also improve the overall rigidity and durability of the entire ABS sensor assembly connected to the vehicle.

[0011] The aforementioned high-temperature resistant ABS sensor can be further configured such that: the connecting block has an axially formed connecting groove, the connecting groove has a strap, and the strap passes through the connecting groove to form a connecting hole for connection with the outer shell.

[0012] The above technical solution, with the connecting groove and strap axially opened on the connecting block, provides a convenient and stable connection method for the fixed connection between the outer casing and the connecting block. By inserting the strap into the connecting groove to form a connecting hole for the outer casing to connect, a tight connection between the outer casing and the connecting block is achieved, which also greatly simplifies the assembly process. The flexibility and adjustability of the strap allow the outer casing to be finely adjusted to adapt to different installation environments or vehicle models, ensuring the accurate positioning and stable operation of the sensor assembly on the vehicle.

[0013] The aforementioned high-temperature resistant ABS sensor can be further configured such that the abutment block is made of soft rubber and is trapezoidal to form a soft rubber suction cup.

[0014] Using the above technical solution, the abutment block is made of soft rubber and designed in a trapezoidal shape to form a soft rubber suction cup. The soft rubber material has good elasticity and plasticity, which can fit tightly to the outer periphery of the vehicle and effectively absorb and disperse the vibration and impact force generated during vehicle operation. The trapezoidal design causes the abutment block to form a soft rubber suction cup effect, which improves the stability and reliability of the connection and can also generate additional adsorption force, making the wiring harness assembly more firmly fixed to the vehicle and preventing displacement or detachment due to bumps or sharp turns.

[0015] The aforementioned high-temperature resistant ABS sensor can be further configured such that: the connector includes a connecting housing, the connecting housing has connecting terminals, and the connecting housing has an insertion interface.

[0016] By adopting the above technical solution and setting connection terminals inside the connector housing, the ABS sensor can stably transmit signals during operation, thereby improving the safety and reliability of the vehicle braking system.

[0017] The aforementioned high-temperature resistant ABS sensor can be further configured such that: the sensor end includes a housing, the housing has fixing plates on both sides, one end of the housing has a wire harness connection end that is fitted onto the housing, and the fixing plates have mounting holes at both ends.

[0018] By adopting the above technical solution, the fixing plate not only enhances the structural strength of the shell, but also plays a role in positioning and support. Through the mounting holes on the fixing plate, the sensor end can be easily connected to other parts of the vehicle, ensuring the accurate installation and stable operation of the sensor on the vehicle.

[0019] The aforementioned high-temperature resistant ABS sensor can be further configured such that the outer casing is made of silicone rubber.

[0020] Using the above technical solution, silicone rubber has good high temperature resistance, which can withstand high temperatures of 200℃-300℃. At the same time, it has excellent cold resistance, weather resistance, electrical insulation and soft elasticity, which can effectively buffer and protect the wire harness from vibration, friction and the influence of the external environment.

[0021] The beneficial effects of this utility model are as follows: the fastener, through the connecting block and the abutment block, enables the wiring harness assembly to be tightly and stably fixed in a specific position on the vehicle, effectively reducing sensor malfunctions caused by shaking or displacement during vehicle operation, improving the working stability and reliability of the ABS sensor, and extending its service life.
