[0030] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0031] like Figures 1-3As shown, the electric bicycle handlebar angle positioning device of this embodiment includes a connecting rod 1, on which a basket bracket positioning pin group 4 and a handlebar positioning structure 2 are provided.

[0032] The basket support positioning nail group 4 includes:

[0033] Positioning nail plate 402 is embedded in the middle or bottom of connecting rod 1.

[0034] Positioning pins are symmetrically arranged on the positioning nail plate 402 and are adapted to the mounting holes of the basket bracket on the frame to be tested.

[0035] The horizontal positioning structure 2 includes symmetrically arranged horizontal positioning forks 202, with the open ends of both horizontal positioning forks 202 facing away from the connecting rod 1.

[0036] Positioning pin plate 402 is embedded on the side of connecting rod 1 facing the frame to be tested.

[0037] Two or three positioning structures are provided on the connecting rod 1.

[0038] When two positioning structures are set on the connecting rod 1, the positioning nail group 4 of the vegetable basket bracket is located at the bottom end of the connecting rod 1.

[0039] When three positioning structures are set on the connecting rod 1, the positioning nail group 4 of the vegetable basket bracket is located in the middle section of the connecting rod 1.

[0040] The positioning pin plate 402 is located in the middle section of the connecting rod 1, and a front fork positioning structure 3 is provided at the bottom end of the connecting rod 1.

[0041] The fork positioning structure 3 includes a fork positioning plate 301 embedded in the connecting rod 1 and a fork positioning rod 302 extending from the fork positioning plate 301 to one side of the frame to be tested.

[0042] The front fork positioning plate 301 and the positioning pin plate 402 are respectively embedded on the front and rear sides of the connecting rod 1 in the direction of the vehicle body.

[0043] The fork positioning rods 302 are symmetrically arranged in groups at both ends of the fork positioning plate 301. There are two fork positioning rods 302 in one group, and one group of fork positioning rods 302 is adapted to the shock absorber on one side of the frame under test.

[0044] Applicable to lightweight electric vehicles as specified in national standards.

[0045] The specific structure and working principle of this application are as follows:

[0046] The positioning device provided in this application, such as Figure 1As shown, the device includes a connecting rod 1, with a basket support positioning pin assembly 4 positioned in the middle of the connecting rod 1. A handlebar positioning structure 2 and a front fork positioning structure 3 are located at both ends of the connecting rod 1. In use, the basket support positioning pin assembly 4 is inserted into the mounting holes of the basket support, aligning the handlebar positioning structure 2 and the front fork positioning structure 3 with the handlebar and front fork. After positioning, the handlebar is tightened, the positioning devices are removed, and assembly is complete.

[0047] Since the basket support positioning pin group 4 is the first to be inserted into the hole and serves as a positioning reference, the basket support positioning pin group 4 needs to be equipped with at least two positioning pins 401. After the positioning pins 401 fall into the hole, they can prevent the positioning device from moving up and down or left and right.

[0048] In order to provide a larger installation space for the positioning nail group 4 of the vegetable basket bracket, a positioning nail plate 402 is embedded in the middle section of the connecting rod 1, and the positioning pin 4 is located on the positioning nail plate 402.

[0049] Reference Figure 2 A fork positioning plate 301 is embedded at the bottom of the connecting rod 1. A fork positioning rod 302 extends from the side of the fork positioning plate 301 facing the frame to be tested. The fork positioning rod 302 is set perpendicular to the connecting rod 1, and there are two sets of fork positioning rods 302, each set having two rods. One set of fork positioning rods 302 is used in conjunction with the front shock absorber on one side.

[0050] The positioning pin plate 402 and the front fork positioning plate 301 are parallel to each other and are respectively embedded on the front and rear sides of the connecting rod 1.

[0051] The lateral positioning structure 2 is located at the top of the connecting rod 1, including a lateral positioning rod 201. A lateral positioning fork 202 extends upward from the side of the lateral positioning rod 201 away from the connecting rod 1. The lateral positioning fork 202 is parallel to the connecting rod 1, with its fork opening vertically upward. The lateral positioning fork 202 is symmetrically arranged at both ends of the lateral positioning rod 201. This upward-facing fork structure has the advantage of allowing for full limitation of the steering handle, providing a limiting basis from the front, rear, and bottom of the steering handle.

[0052] As an alternative implementation, the fork opening of the transverse positioning fork 202 can also be configured to face the frame to be tested. Facing the frame to be tested makes it easier to push the positioning device to fit the frame to be tested.

[0053] like Figure 3 As shown, if it is necessary to apply it to products without a front shock absorber, the front fork positioning structure 3 can be eliminated according to the vehicle structure, and the link 1 to the basket bracket positioning system can be shortened to form a shorter and smaller positioning device.

[0054] In use, the left and right sides of the handlebar horizontal positioning structure 2 are engaged with the horizontal positioning forks 202 from bottom to top into the handlebar horizontal position. Then, the positioning pins 401 of the basket bracket positioning structure are engaged with the basket mounting holes on the basket bracket to achieve basket bracket positioning. The front fork positioning structure 3 is engaged with the front shock absorber. This three-point positioning ensures that the handlebar angle and the front fork angle are on the same center line, guaranteeing assembly consistency. Then, the handlebar is tightened, and the device is removed after tightening.

[0055] The advantage of this application is that the positioning device has a simple structure, low weight, and is easy to use. During the assembly process, since there are three positions that are mutually constrained with the vehicle frame to be tested, the force required to support the positioning device is low, and the operation difficulty is significantly reduced.

[0056] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
