Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a sensor component used for automobile steering. Background Art

[0002] Automotive sensors are components used in vehicles to collect information. Depending on the object being collected, they can be categorized as speed sensors, tire pressure sensors, distance sensors, and more. These sensors provide a more convenient and comprehensive understanding of vehicle conditions. Steering sensors monitor obstacles around the vehicle during steering to prevent collisions.

[0003] During vehicle driving, the corners of the vehicle are usually blind spots. When the vehicle turns or drives in complex terrain, the driver cannot observe the situation in the blind spots of the vehicle. When the vehicle turns, scratches are likely to occur. Traditional vehicle distance sensors can only detect the distance of a small space outside the vehicle, and the detection range is not large enough. A larger monitoring range is required in the blind spot range. Traditional detectors cannot perform large-scale scanning and detection. When the vehicle turns, there is still a blind spot in the direction of the vehicle turning, which is not conducive to avoiding obstacles in the blind spot range of the vehicle corners.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 5 , the utility model provides an embodiment: a sensor assembly for automobile steering, comprising a protective cover 1 and a shell, the shell being composed of a top plate 2, a positioning member 3 and a bottom plate 4;

[0021] The housing houses a travel plate 5, on which an infrared distance sensor 51 and a servo motor 53 are mounted. The infrared distance sensor 51 is a measuring system using infrared light as its medium. It features a pair of infrared signal transmitting and receiving diodes. The infrared light emitted by the sensor is reflected by an object, then reflected back to the sensor. The CCD image processor then processes the received data based on the time difference between transmission and reception. The signal processor calculates the distance to the object. The servo motor 53 can control speed and achieve highly accurate positioning. It converts voltage signals into torque and speed to drive the controlled object. A bevel gear 52 is attached to one side of the servo motor 53, and a rack 21 is located on the lower surface of the top plate 2.

[0022] A rotating shaft 41 is provided on the surface of the base plate 4, and one end of the travel plate 5 is rotatably mounted on the surface of the rotating shaft 41. Limiting plates 54 are provided on the surface of the travel plate 5, and the rack 21 is located between the limiting plates 54. The bevel gear 52 meshes with the rack 21. During vehicle steering, the servo motor 53 drives the bevel gear 52 to rotate. The bevel gear 52 cooperates with the rack 21 to drive the travel plate 5 to rotate along the rotating shaft 41, causing the infrared distance sensor 51 to swing back and forth in the protective cover 1. The infrared distance sensor 51 emits infrared rays through the acrylic protective cover 1, repeatedly scanning the blind spot range of the vehicle's steering field. When the distance to an obstacle is less than the warning distance, a signal can be transmitted to the vehicle's central control platform, issuing an alarm, prompting the driver to avoid the blind spot obstacle in the steering path.

[0023] A limiting groove 11 is provided on the inner wall of the protective cover 1 , and a limiting slider 55 is provided on one end surface of the travel plate 5 . When the travel plate 5 moves, the limiting slider 55 slides in the limiting groove 11 to limit one end of the travel plate 5 .

[0024] Protective cover 1 is made of transparent acrylic, allowing infrared rays emitted by infrared distance sensor 51 to pass through, ensuring the vehicle's aesthetic appearance while also ensuring the proper function of infrared distance sensor 51. Positioning member 3 is provided with a cable routing hole 56, which allows wiring for infrared distance sensor 51 and servo motor 53 to be routed, facilitating connection between the sensor assembly and the vehicle's central control platform.

[0025] Working principle: In actual application, the sensor assembly can be installed at the corners of the vehicle to monitor the blind spots of the four corners of the vehicle. During the vehicle steering process, the servo motor 53 drives the bevel gear 52 to rotate, and the bevel gear 52 cooperates with the rack 21 to drive the stroke plate 5 to rotate along the rotating shaft 41, so that the infrared distance sensor 51 swings back and forth in the protective cover 1. The infrared distance sensor 51 emits infrared rays through the acrylic protective cover 1 to repeatedly scan the blind spot range of the vehicle's steering. When the distance to an obstacle is less than the warning distance, it can transmit a signal to the car's central control platform to issue an alarm, prompting the driver to avoid the blind spot obstacles in the steering path.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
