Description

Technical Field

[0001] The present invention relates to the technical field of electric two-wheeled vehicles, and in particular to an electric vehicle handlebar riser structure and an electric vehicle. Background Art

[0002] In the electric two-wheeled vehicle industry, the basket fork of an electric vehicle, also known as the light fork, is a key accessory for installing and fixing the front basket. It mainly serves to connect the basket to the frame. The basket fork component is often designed to be assembled on the riser part of the upper end of the front fork of the frame. In the prior art, the basket fork component is clamped between the front fork riser and the fixing nut by means of compression and fixation using a fixing nut that is sleeved on the front fork riser. However, this fixing method has an inherent design flaw. Since the fixing nut will drive the basket fork to rotate synchronously along the rotation direction of the fixing nut during the rotation and locking process, after the fixing nut is rotated and locked, the angle of the basket fork will be deflected to a certain extent and will no longer be facing the front of the frame. A misaligned basket fork will cause the angles of the components fixed on the basket fork, such as the basket and headlights, to become skewed, which will in turn affect the inconvenience of vehicle use and even cause riding safety hazards.

[0003] To ensure the correct angle of the basket forks and maintain a standardized and consistent vehicle appearance, secondary calibration using tools such as hammers is often performed after tightening. This reduces production efficiency and increases vehicle manufacturing costs. Furthermore, calibration relies heavily on operator experience, making visual inspection difficult to accurately determine. This can lead to angle deviations between individual products and poor product consistency. Summary of the Invention

[0004] The present invention aims to address the defects of the prior art and provide an electric vehicle handlebar riser structure and an electric vehicle.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] In a first aspect, a handlebar riser structure for an electric vehicle is provided, comprising a handlebar riser assembly, characterized in that it also comprises a basket fork assembly and a handlebar cross tube fixing assembly, wherein the basket fork assembly comprises a first riser connection portion and a basket connection portion, wherein the first riser connection portion and the basket connection portion are an integrated structure, wherein the lower end of the handlebar riser assembly is fixedly connected to the first riser connection portion, wherein the basket connection portion is used to connect to the basket, wherein the handlebar cross tube fixing assembly comprises a second riser connection portion and a handlebar cross tube connection portion, wherein the second riser connection portion and the handlebar cross tube connection portion are an integrated structure, wherein the upper end of the handlebar riser assembly is fixedly connected to the second riser connection portion, wherein the handlebar cross tube connecting portion is used to connect to the handlebar cross tube.

[0007] Furthermore, a riser connection hole is provided on the first riser connection portion, and the lower end of the handlebar riser assembly is passed through and fixedly welded to the riser connection hole.

[0008] Furthermore, the first vertical pipe connecting portion and the vehicle basket connecting portion are arranged perpendicular to each other, and a vehicle basket connecting hole is provided on the vehicle basket connecting portion.

[0009] Furthermore, the handlebar cross tube connection portion includes a first handlebar cross tube connection portion and a second handlebar cross tube connection portion, and the first handlebar cross tube connection portion and the second handlebar cross tube connection portion are respectively located on the front and rear sides of the second vertical tube connection portion, and are used to cooperate with the handlebar cross tube pressure cover to connect the handlebar cross tube.

[0010] Furthermore, the first handlebar cross tube connecting portion and the second handlebar cross tube connecting portion are provided with a gland connecting hole for connecting the handlebar cross tube gland.

[0011] Furthermore, there are at least three gland connection holes.

[0012] Furthermore, the cross section of the second riser connection portion is semicircular, matching the shape of the handlebar cross tube.

[0013] Furthermore, two headlight connection parts are integrally connected to the left and right sides of the first handlebar cross tube connection part, and the headlight connection part and the first handlebar cross tube connection part are perpendicular to each other.

[0014] Furthermore, the handlebar riser assembly is provided with a pin hole, and the opening direction of the pin hole is arranged along the radial direction of the handlebar riser assembly.

[0015] In a second aspect, an electric vehicle is provided, characterized in that it includes the electric vehicle handlebar riser structure according to any one of claims 1 to 9.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The basket fork fixing method has been changed from traditional nut locking to welding to the handlebar stem assembly. The welding is performed through mechanized assembly and welding robots to ensure the consistency of welding angle and position each time. This eliminates the step of manual secondary correction, reduces body differences, improves product assembly accuracy, avoids angular deviation from the manufacturing source, and ensures the spatial coordination of components such as the headlight and basket.

[0018] 2. A connection structure that cooperates with the handlebar cross tube gland is reserved on the handlebar cross tube fixing assembly to achieve relative fixation of the handlebar cross tube and the handlebar riser.
