Description

Technical Field

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

[0002] Modern cars' ABS systems are equipped with electromagnetic induction wheel speed sensors, which can be installed in the final drive or transmission, and come in two basic types: active and passive. Wheel speed sensors are used to measure the rotational speed of a car's wheels.

[0003] An integrated wheel speed sensor, as disclosed in authorization announcement number CN216670027U, includes a wheel speed sensor body with an internal wiring harness, an external wiring harness, and a connector for interlocking with the wiring harness of external electrical appliances. The beneficial effect of this utility model is that integrating the wheel speed sensor with the EPB wiring harness improves the aesthetics of the assembly.

[0004] While the aforementioned patents significantly improve assembly efficiency and wiring neatness through integrated design, pre-integrating the wheel speed sensor harness and EPB harness into a single assembly means that the length and shape of all its branches are fixed at the factory. This "tailor-made" approach may achieve optimal layout on specific vehicle models, but it may not be able to cope with design changes and different installation environments. Utility Model Content

[0014] Preferably, the stretching mechanism further includes a spring movably sleeved on the outside of the telescopic wire harness, with both ends of the spring abutting against a limiting ring and a limiting groove, respectively.

[0015] Preferably, the main line segment, the secondary line segment, and the telescopic wire harness are all four-core cables.

[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] like Figure 1-4 As shown, this utility model provides a technical solution:

[0026] An integrated wheel speed sensor includes a main wire segment 1 and a secondary wire segment 2, with a tensioning mechanism between them. A connector 3 is integrally formed at the end of the main wire segment 1 away from the tensioning mechanism. The tensioning mechanism includes a wire harness conduit 10 fixedly connected to the end of the main wire segment 1 away from the connector 3, and a telescopic wire harness 11 fixedly connected to the end of the secondary wire segment 2 away from the Y-connector 4. The end of the telescopic wire harness 11 away from the secondary wire segment 2 is fixedly connected to the main wire segment 1. The tensioning mechanism also includes a limiting groove 12 formed in the inner wall of the wire harness conduit 10, and a limiting ring 13 fixedly connected to the outer periphery of the connection between the secondary wire segment 2 and the telescopic wire harness 11. The limiting ring 13 and the limiting groove 10 are connected in series. 2. Clearance fit. The tensioning mechanism further includes a spring 9 that is movably sleeved on the outside of the telescopic wire harness 11. The two ends of the spring 9 abut against the limiting ring 13 and the limiting groove 12, respectively. A Y-type connector 4 is fixedly connected to the end of the secondary wire segment 2 away from the tensioning mechanism. A connection mechanism is provided at the end of the Y-type connector 4 away from the secondary wire segment 2. The connection mechanism includes an EPB end wire harness 5 and a wheel speed end wire harness 6 connected in parallel to the end of the Y-type connector 4 away from the secondary wire segment 2. An EPB caliper plug end 7 and a wheel speed magnetic induction end 8 are fixedly connected to the ends of the EPB end wire harness 5 and the wheel speed end wire harness 6 away from the Y-type connector 4, respectively. The main wire segment 1, the secondary wire segment 2 and the telescopic wire harness 11 are all four-core cables.

[0027] In this embodiment, by using a stretching mechanism, the total length of the main wire segment 1 and the secondary wire segment 2 can be adaptively adjusted according to the installation distance, which solves the problem that the fixed total length of the wire harness cannot adapt to different installation environments or design changes.

[0028] By integrating the EPB end wire harness 5 and the wheel speed end wire harness 6 onto the same sub-segment 2 through the Y-type connector 4 and sharing a set of tensioning mechanism, the synchronous and rapid wiring and fixing of the two wire harnesses is realized, which solves the problem of cumbersome assembly process and long working time of the split wire harness.

[0029] Working principle: When installing the sensor, the installer can manually stretch the secondary wire segment 2 according to the actual installation position of the EPB caliper and the wheel speed sensor on the vehicle. The secondary wire segment 2 drives the telescopic wire harness 11 to extend out of the wire harness conduit 10 through the limit ring 13. At this time, the spring 9 is stretched and accumulates the tension for retraction. When the EPB caliper connector 7 and the wheel speed magnetic sensor 8 are connected to the corresponding components, the installer releases the hand. Under the elastic tension of the spring 9, the stretching mechanism will automatically retract to a suitable length and maintain tension, thereby eliminating the redundancy and looseness of the wire harness.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
