Description

  The present invention relates to a radar sensor having a fine adjustment function for a vehicle that moves backward, and more particularly, to a radar sensor for a vehicle that moves backward that can finely adjust a detection angle after installation.

  Advances in radar electronics and increased traffic safety awareness have led to the development of radar equipment for vehicles such as passenger cars and trucks. In particular, radar is suitable for assisting such a vehicle to move backward safely. Information for knowing whether there is an obstacle behind by sending out ultrasonic waves and receiving the reflection so that the vehicle can be moved backwards and parked successfully. To the driver. For some drivers, a video camera provided at the back of the vehicle is suitable, and the video camera can optimally understand the road conditions behind the vehicle. For both ultrasound and video cameras, an accurate sensing range of the detection component is important. Therefore, how to accurately set the sensing range is an important issue.

  However, conventional radar backward support products do not have a fine adjustment function after installation. Therefore, the driver needs to adjust and re-equip the radar several times through trial and error in order to obtain the optimum angle, which is cumbersome and boring and cannot be set to an accurate range by an amateur. Even dangerous.

  Accordingly, an object of the present invention is to provide a radar detector that has a fine adjustment function for reversing the vehicle and enables fine adjustment of a sensing angle after installation on the vehicle.

  In order to achieve the above object, a radar sensor for a reverse vehicle having a fine adjustment function is provided. The radar sensor having a fine adjustment function includes a base, a sensor module, a brake, and an adjustment component. A round chamber is formed on the base and a component room is formed at a corresponding position of the chamber. The component room includes first and second openings. The first opening communicates with the outer surface of the base, and the second opening communicates the chamber with the component room. The second opening includes a packing block within the opening. The sensor module includes a truncated sphere that corresponds to the substantially spherical inner wall of the chamber and conforms to the inner wall to provide a wide viewing angle and orientation adjustment. The brake is shaped along the inner surface of the component room and is associated with the inner surface of the packing block. The adjustment component is set in the second opening of the base and is coupled to the brake.

  Thus, when the radar sensor described above is mounted on the back of the vehicle, the pivot of the sensor module with respect to the base can be used for fine adjustment of the angle of the sensor module. After adjustment to the proper angle, the adjustment component is manipulated through the outer surface of the base to control the movement of the brake. Thereby, the brake pushes down the packing block, so that the sensor module is fixed in a desired position in the chamber of the base. Therefore, the structure provided with the spherical design of the sensor allows convenient fine adjustment of the angle of the sensor as long as the vehicle reverse radar sensor is installed on the vehicle.

[Example]
Referring to FIG. 1, a radar detector for vehicle reversal includes a base 10 and a sensor module 20 having a truncated spherical body. The sensor module 20 can change the sensing angle by the super wide angle method in the base 10 so as to facilitate fine adjustment of the angle after the radar detector is installed, and is shown in FIG. Although not, it can be locked by an adjustment component installed on the outer surface of the base 10. The following description provides a detailed example structure for an example of the preferred embodiment of the present invention.

  Referring to FIG. 2, the preferred embodiment of the present invention includes a base 10, which is a first housing 11 that can be coupled to form the base and a front housing 11 that is a second housing. A housing 12 is provided. A first circular opening 111 and a second circular opening 121 corresponding to each other are formed in each of the front housing 11 and the back housing 12. The first circular opening 111 has an arched periphery, and the second circular opening 121 has an arched periphery that is a mirror image of the first circular opening periphery 111, and as a result. When both the front and back housings 11, 12 are joined, a frustospherical chamber is formed that fits and receives the frustospherical body of the sensor module 20. Further, in the front housing 11 and the back housing 12, two first slots 112 and two second slots 122 are formed on opposite surfaces of the lateral wall, respectively. Each slot 112, 122 is aligned with the open end of the first slot 112 and the open end of the second slot 122 when the housings 11, 12 are joined together, thereby diametrically extending the sensor module 20. Two passages are defined for receiving the pivots 22 projecting from the locations opposite to each other.

  Referring to FIG. 3, a space is formed in the upper right corner of the first housing or front housing 11 and in the corresponding upper left corner of the second housing or back housing 12, whereby the housing is formed. A component room 13 is formed when 11 and 12 are combined. The component room 13 includes a first opening 131 and a second opening 132 that is perpendicular to the first opening. The first opening 131 has an outlet opening at the end face of the front housing 11. The second opening 132 has an outlet opening to the arched peripheral portion of the front housing 11 and includes the packing block 15. The adjustment component 14 is set in the second opening 132. In this embodiment, the adjustment component 14 is a screw.

  Furthermore, the brake 30 is formed along the inner surface of the component room 13. The brake 30 includes a frame 31 for the brake shoe 32, and the frame can slide in the front-rear direction. The frame 31 has an opening 311 on a side wall facing the first opening 131, and the brake shoe 32 has a hole 321 that is formed in parallel to the longitudinal side surface of the brake shoe 32 and corresponds to the opening 311 of the frame 31. . The brake shoe 32 includes a notch at one end, and the notch 33 having a screw hole corresponding to the hole 321 of the brake shoe 32 is accommodated in the notch. In this way, the adjustment component 14 in the first opening 131 sequentially passes through the opening 311 of the frame 31 and the hole 321 of the brake shoe 32 so as to be connected to the notch 33 by a screw connection method. The brake shoe 32 has an inclined wall 322 facing the side wall in which the second opening 132 is formed. When the adjustment component 14 rotates forward and backward, the brake shoes 32 move back and forth respectively, and as a result, the brake shoes 32 push the packing block 15 into the spherical chamber.

  Still referring to FIGS. 2 and 3, the sensor module 20 includes a sensor mounted within a body, the body including a truncated sphere 21 adapted to the chamber of the base 10. A pivot 22 provides a pivot range for the sensor and the truncated sphere 21. Further, the sensor module 20 includes a detection terminal 23. The detection terminal 23 protrudes beyond the first circular opening 111 of the front housing 11. Sensor parts are mounted on the detection terminal 23. The sensor component is an ultrasonic transceiver or an imaging component.

  A preferred embodiment of the present invention after the integration of the components described above is shown in FIGS. Prior to installation of the radar sensor of the present invention, the adjustment component 14 is held in its original stationary position. The motion block or brake shoe 32 is located in the component room 13 and does not push the packing block 15. At this point, the packing block 15 is located in the second opening 132. After completing the installation of the radar sensing device, the angle of the sensor module 20 can be adjusted. Since the packing block 15 is not in the operating position, the truncated sphere 21 of the sensor module 20 and the chamber of the base 10 are not fixed to each other, and the sensor module 20 can be moved freely. 4, 5 and 6 show various movements of the truncated sphere 21 with respect to the base 10. After the adjustment to the fixed position, the adjustment component 14 installed on the outer surface of the front housing 11 can be rotated inside the first opening 131. At this point, the brake shoe 32 is pushed forward, and the brake shoe 32 pushes the packing block 15 down in the second opening 132 as shown in FIG. Therefore, the packing block 15 abuts so as to engage with the truncated sphere 21 of the sensor module 20. Thereby, the sensing range is adjusted and fixed.

  As a result, the present invention contributes to providing a fine adjustment function to the radar sensing device, and can adjust a wide viewing angle and direction of the sensor module. In addition, the base includes a brake that operates in conjunction with an adjustment component, and the adjustment component is operable from outside the base to secure the sensor module in the adjusted angle and direction. Since the lock mechanism can be operated outside the base, fine adjustment can be conveniently performed to accurately set the sensing range after the radar sensing device is installed.
