[0002] The full name of the reverse radar is "reverse anti-collision radar", also called "parking assist device", or "reverse computer warning system". This device can judge the distance of obstacles and prompt the situation of obstacles around the vehicle to improve the safety during reverse parking. The reverse radar consists of ultrasonic sensors, controllers, displays, alarms and other parts. During the production and installation of the reverse radar, it is necessary to test its detection range to ensure the reliability of the reverse radar during use.
[0003] For example, the Chinese utility model patent with the publication number CN218497144U provides a fixed-distance obstacle tube for an automotive ultrasonic reverse radar sensor. All the materials of this device are made of metal to avoid the influence of metal materials on the accuracy of test results. And it is provided with a sponge that can absorb the ultrasonic waves repeatedly emitted by the reverse radar sensor, so that there is only one vertically reflected ultrasonic wave in the fixed-distance obstacle tube, ensuring that the detected distance of the automotive ultrasonic reverse radar sensor is unique. The setting of the fixed bracket can ensure the stability of the automotive ultrasonic reverse radar sensor during the test process.
[0004] However, in the current test standard, there is no quick confirmation method for the placement position of the detection rod. In the detection range test, if the placement position of the detection rod is confirmed for different-width vehicle models, it will take too much time, with too low efficiency, and it is also impossible to ensure whether the center of the detection rod is accurately at the placement position. Therefore, in view of this, a reverse detection range testing device is proposed to solve the above technical problems. Content of the Utility Model

In the detection range test, if the placement position of the detection rod is confirmed for different-width vehicle models, it will take too much time, with too low efficiency, and it is also impossible to ensure whether the center of the detection rod is accurately at the placement position.

[0026] The embodiments of the technical solutions of the present invention will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, so they are only examples and cannot be used to limit the protection scope of the present invention.
[0027] Embodiment:
[0028] As Figure 1As shown in the figure, the present utility model provides a device for testing the reverse detection range, which includes a positioning cloth 101. Multiple groups of positioning points 102 are arranged on the positioning cloth 101. The multiple groups of positioning points 102 are arranged at equal intervals horizontally and vertically. Preferably, in some embodiments, the distance between every two adjacent groups of positioning points 102 horizontally or vertically is 100 mm. A detection rod 201 is arranged on the positioning cloth 101. The axis of the detection rod 201 coincides with one group of positioning points 102. A base 202 is arranged at the bottom of the detection rod 201. The diameter of the base 202 is larger than the diameter of the detection rod 201, and the center of the base 202 coincides with the axis of the detection rod 201.
[0029] During use, lay the positioning cloth 101 at the rear of the vehicle so that the positioning points 102 at both ends of the positioning cloth 101 are aligned with both sides of the rear of the vehicle, and then the test can be carried out. During the test, place the detection rod 201 on the positioning cloth 101 so that the axis of the detection rod 201 coincides with the positioning points 102, and the position of the detection rod 201 can be quickly determined without measuring the position of the detection rod 201 every time it is placed, improving the test efficiency. And the detection rod 201 is stably supported by the base 202 to prevent the detection rod 201 from tipping over.
[0030] As Figure 1 、 2 shown, in this embodiment, an indicating ring 103 is arranged on each group of positioning points 102. The diameter of the indicating ring 103 is the same as the diameter of the base 202. The base 202 is located within one group of indicating rings 103. Scale lines 104 are arranged between every two adjacent groups of indicating rings 103. Through the arrangement of the indicating ring 103, the detection rod 201 can be quickly positioned when placed. Placing the base 202 completely within the indicating ring 103 can ensure that the axis of the detection rod 201 coincides with the positioning cloth 101. Through the arrangement of the scale lines 104, it is convenient to finely adjust the position of the detection rod 201 more precisely.
[0031] As Figure 1 shown, in this embodiment, the diameter of the base 202 is 100 mm, the diameter of the detection rod 201 is 75 mm, and the height of the detection rod 201 is 1000 mm. The length of the positioning cloth 101 is greater than 3000 mm, and the width is greater than 1000 mm. The sizes of the base 202, the detection rod 201 and the positioning cloth 101 and the distance between the positioning points 102 can be adjusted according to actual needs to meet the test requirements. In addition, it can be understood that the distance between two adjacent groups of positioning points 102 is preferably 100 mm, which is convenient for calculating the moving distance of the detection rod 201 when placed and the distance between the placement position and the rear of the vehicle. And a blank area is reserved at one end in the width direction of the positioning cloth 101 to facilitate distinguishing the direction of the positioning cloth 101.
[0032] As Figure 2As shown, in this embodiment, a cavity for accommodating the wound positioning cloth 101 is provided inside the detection rod 201. An internal thread 203 is provided at the end of the detection rod 201, and a shielding cover 301 connected through an external thread 302 is arranged inside the internal thread 203. A rotation groove 303 is provided on the shielding cover 301. After use, the positioning cloth 101 can be wound and placed inside the detection rod 201 for storage, and the shielding cover 301 can be installed through the cooperation of the internal thread 203 and the external thread 302. The rotation groove 303 is provided to facilitate the opening or closing of the shielding cover 301, which is convenient for protecting and taking the positioning cloth 101 for use.
[0033] Specific usage method and beneficial effects of the present utility model:
[0034] When the device is in use, the positioning cloth 101 is placed behind the vehicle, ensuring that the rearmost end of the vehicle coincides with the cut-off line at the frontmost end of the positioning cloth 101, and the center line of the vehicle coincides with a certain row of positioning points 102 on the positioning cloth 101. Then, the vehicle width is rounded up to obtain the test width, and the left and right values of the test width are obtained by dividing the test width by 2. The left and right boundary lines of the vehicle are adjusted by the positioning cloth 101 to coincide with the corresponding positioning points 102 on the positioning cloth 101. At this time, the width of the detection range is confirmed, and the points at every 100 mm in terms of width and length within the range from the points in the second column of the test left boundary line to the points in the second column of the test right boundary line are the detection points. Finally, the detection rod 201 is placed on the positioning point 102, making the center of the base 202 at the bottom thereof coincide with the positioning point 102, thus completing the precise placement of the position of the detection rod 201. By placing the detection rod 201 through this device, the accuracy of the placement position of the detection rod 201 is effectively guaranteed, which can cover all vehicle models, is convenient to carry, quick to place, easy to operate, effectively improves the test efficiency, and at the same time solves the problems of long confirmation time for the placement position of the detection rod 201 and insufficient accuracy.
