Technical Field

[0002] Vehicle-mounted millimeter-wave radar sensors are one of the core sensing devices in modern intelligent vehicles, especially those equipped with advanced driver assistance systems (ADAS) and autonomous driving functions. Utilizing electromagnetic waves in the millimeter-wave band for environmental detection, they offer high precision and all-weather operation, making them a key technology for safe driving. The sensor transmits signals to an external controller via a wiring harness.
[0003] In the prior art, such as Chinese Patent No. CN223181745U, a sensor wiring harness fixing structure includes a sensor housing. A wiring harness outlet is located at one end of the sensor housing, and a pressure plate receiving cavity is located at the wiring harness outlet. Multiple wiring harness fixing grooves and multiple wiring harness outlet grooves are respectively formed on two parallel cavity walls forming the pressure plate receiving cavity. A pressure plate is installed inside the pressure plate receiving cavity. The pressure plate includes a cover plate body and a pressure plate body. A wiring harness guide groove is formed on the pressure plate body. The wiring harness passes through the wiring harness fixing groove and the wiring harness guide groove and is then exited through the wiring harness outlet groove. This utility model provides a sensor wiring harness fixing structure with a simple structure that effectively prevents wiring harness breakage due to pulling and ensures the stability of the wiring harness connection. It solves the technical problem in the prior art where the sensor wiring harness is easily pulled and broken when transmitted from the soldered end of the PCB board to the outside of the housing, leading to sensor malfunction.
[0004] While the above solutions effectively prevent wire harness breakage due to pulling, once the wire harness is installed and fixed inside the equipment or vehicle, it is easily damaged by friction, vibration, or external factors, thereby reducing its service life and causing short circuits that affect data transmission. Moreover, the above solutions only fix the wire harness at the connector, and the entire wire harness is prone to tangling, appearing messy and affecting the efficiency of later maintenance.

Then, the rectangular frame is embedded into the T-shaped grooves opened on both sides of the inner surface of the U-shaped plate through the T-shaped plate. After the T-shaped plate is embedded into the T-shaped groove, the limiting pin is embedded into the limiting hole under the elastic force of the limiting spring, positioning the T-shaped plate and making the T-shaped plate more stably embedded inside the U-shaped plate.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0041] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0042] Example 1, as Figure 1-4 As shown, this utility model provides a wire harness fixing guide groove for vehicle-mounted millimeter-wave radar sensors, including: a U-shaped plate 1, a baffle 102, a fixing component, and a positioning component;
[0043] The fixing components include: multiple T-shaped grooves 108 are provided on both sides of the inner surface of the U-shaped plate 1, the multiple T-shaped grooves 108 are evenly divided into two groups, a T-shaped plate 111 is slidably installed inside the T-shaped grooves 108, and a rectangular frame 105 is fixedly installed on the top of the T-shaped plate 111.
[0044] Among them, the T-shaped plate 111 can drive the rectangular frame 105 to be disassembled, which facilitates the fixing of the wire harness;
[0045] A nut 107 is fixedly installed at the top center of the rectangular frame 105. An adjusting bolt 106 is installed on the internal thread of the nut 107. The adjusting bolt 106 passes through the rectangular frame 105. A rubber pad 113 is fixedly installed at the bottom of the adjusting bolt 106.
[0046] Among them, the rotating adjusting bolt 106 can drive the rubber pad 113 to position the wire harness inside the rectangular frame 105, so that it is more stably embedded inside the rectangular frame 105. The rubber pad 113 can not only increase the friction, but also prevent damage to the wire harness positioning point.
[0047] The bottom of the T-shaped plate 111 has a limiting hole 112. Both sides of the bottom of the U-shaped plate 1 are movably fitted with multiple limiting pins 109. The outer surface of the limiting pin 109 is fixedly connected to a limiting spring 110. The other end of the limiting spring 110 is fixedly connected to the bottom of the U-shaped plate 1.
[0048] In this embodiment, the limiting pin 109 is embedded inside the limiting hole 112 to position the T-shaped plate 111, so that the T-shaped plate 111 is more stably embedded inside the T-shaped groove 108, and the T-shaped plate 111 is connected to the U-shaped plate 1.
[0049] Example 2, as Figure 1-4 As shown, the positioning assembly includes: an adjusting screw 103 threadedly installed at the top center of the baffle 102; two return springs 116 fixedly connected to the bottom of the baffle 102; and a positioning plate 117 fixedly installed at the other end of the return springs 116.
[0050] The rotating adjusting screw 103 can push the positioning plate 117 to move down, so that the positioning plate 117 positions the wire harness inside the U-shaped plate 1. When the adjusting screw 103 rotates in the opposite direction, the positioning plate 117 is reset under the action of the reset spring 116 and no longer clamps the wire harness.
[0051] The bottom of the positioning plate 117 is provided with multiple arc-shaped grooves 118;
[0052] Among them, the arc-shaped groove 118 can better fit with the wire harness and improve the stability of the wire harness;
[0053] L-shaped grooves 119 are provided on both sides of the top of the U-shaped plate 1.

[0056] Working principle: The wire harness is embedded inside the U-shaped plate 1, and both ends of the wire harness are embedded inside the rectangular frame 105.

Then, the rectangular frame 105 is embedded inside the T-shaped groove 108 opened on both sides of the inner surface of the U-shaped plate 1 through the T-shaped plate 111. After the T-shaped plate 111 is embedded inside the T-shaped groove 108, the limiting pin 109 is embedded inside the limiting hole 112 under the elastic force of the limiting spring 110, positioning the T-shaped plate 111 and making the T-shaped plate 111 more stably embedded inside the U-shaped plate 1. The rectangular frames 105 on both sides can be disassembled for easy adjustment according to the length of the wire harness, so that the rectangular frames 105 are better embedded inside the U-shaped plate 1. Positioning the two ends of the wire harness can make the wire harness more stably fixed inside the U-shaped plate 1.
[0057] The L-shaped plates 114 on both sides of the bottom of the baffle 102 are embedded in the L-shaped grooves 119, so that the baffle 102 and the U-shaped plate 1 are connected as one unit. The baffle 102 can protect the wire harness inside the U-shaped plate 1. Then, rotate the adjusting screw 103 to push the positioning plate 117 down, so that the positioning plate 117 fits with the wire harness. The bottom of the positioning plate 117 is provided with multiple arc-shaped grooves 118. The arc-shaped grooves 118 can fit better with the wire harness, so that the wire harness is more stably fixed inside the U-shaped plate 1, preventing the wire harness inside the U-shaped plate 1 from shaking, rubbing or external factors, making it more stable and improving the service life of the wire harness.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
