Many specific details are set forth in the following description to facilitate a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0028] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0029] In the present application, unless otherwise clearly specified and limited, the terms "mounted", "connected", "coupled", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0030] In this application, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply indicates that the horizontal height of the first feature is less than that of the second feature.

[0031] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0032] Embodiment

[0033] This embodiment provides a device for positioning measurement points of the low-speed warning sound of an electric vehicle, as Figure 1 shown, including: a bracket 1, a cross positioning component 2 and a planar positioning member 3. The bracket 1 is arranged at the front end or the rear end of the vehicle. The planar positioning member 3 is detachably connected to the bracket 1 and is used to position the foremost end or the rearmost end of the vehicle. The cross positioning component 2 is arranged above the planar positioning member 3 and is detachably connected to the bracket 1 and is used to position the measurement point location.

[0034] In this embodiment, the tripod of the bracket 1 is arranged perpendicular to the ground, and the length of the bracket 1 should be greater than 1.2 m to facilitate the positioning of the measurement point.

[0035] The cross positioning component 2 is arranged parallel to the ground and can move along the axial direction of the bracket 1. As Figure 2 shown, the cross positioning component 2 includes a horizontal rod 21 and a laser emitter 22. The horizontal rod 21 is connected to the bracket 1 through a first mounting bracket 23 and is arranged perpendicular to the center line of the vehicle. The laser emitter 22 is connected to the first mounting bracket 23 through a second mounting bracket 24. The laser emitted by the output end of the laser emitter 22 is aligned with the center position of the vehicle logo to determine the center line of the vehicle and make the axial direction of the laser emitter 22 coincide with the center of the vehicle.

[0036] In this embodiment, the length of the horizontal rod 21 is 4 m. The first mounting bracket 23 is arranged in the middle of the horizontal rod 21, and the distances from the first mounting bracket 23 to both ends are both 2 m to facilitate the quick determination of the measurement point location.

[0037] As Figure 3 shown, both ends of the horizontal rod 21 are provided with support rods 25 rotatably connected thereto. When retracted, they are parallel to the horizontal rod 21. When fully deployed, they rotate 90 degrees to be parallel to the bracket 1 and the end of the support rod 25 that is not connected to the horizontal rod 21 points to the ground.

[0038] In this embodiment, the length of the support rod 25 is 1.2 m. After being fully deployed, one end abuts against the ground, which can prevent the two ends of the horizontal rod 21 from sagging due to gravity and reduce the error of measuring point positioning.

[0039] As Figure 4 shown, the planar positioning member 3 is connected to the bracket 1 through a third mounting bracket 31. It is provided with a positioning surface 32 perpendicular to the center line of the vehicle. The positioning surface 32 abuts against the vehicle and is used to determine the foremost and rearmost ends of the vehicle.

[0040] When the present utility model is in use, first, the planar positioning member 3 is abutted against the front end or the rear end of the vehicle to determine the foremost or rearmost end of the vehicle. Subsequently, the laser emitted from the output end of the laser emitter 22 is aligned with the center position of the vehicle logo to determine the center line of the vehicle. Finally, the support rod 25 is fully deployed, and the first mounting bracket 23 is adjusted so that the support rod 25 abuts, and thus the measuring point positioning can be completed.

[0041] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0042] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
