Description

Handlebar and front fork positioning device

Technical Field

The application belongs to the electric motor car field, and specifically speaking especially relates to a handlebar and front fork positioner.

Background

In the electric vehicle industry, the handle bars are generally inserted into the front fork stem through the handle stem, and the handle stem is tightened in the front fork stem through the inclined nut. In the assembling process of the handlebar and the front fork, if the torsion applied to the inclined nut is too large, the stress concentration of the connecting part of the handlebar vertical pipe and the front fork vertical pipe can be caused, and the damage can be caused in serious cases. Secondly, because the existing electric vehicle mostly adopts the form of assembling the handlebar and the front fork, the postures of the handlebar and the front fork need to be continuously adjusted in the assembling process, and the handlebar and the front wheel can be ensured to be upright and vertical.

Disclosure of Invention

An object of the application is to provide a handlebar and front fork positioner, its quick location that can realize handlebar and front fork, and can prevent in the assembling process that the connection position that stress concentration caused from damaging.

In order to achieve the purpose, the method is realized by the following technical scheme:

handlebar and front fork positioner in this application, including handlebar and front fork, the handlebar passes through the handlebar riser and inserts in the front fork riser of front fork, be provided with the fixture block on the handlebar riser, processing has on the terminal surface of front fork riser with fixture block complex draw-in groove, the handlebar riser inserts behind the front fork riser the fixture block be located the draw-in groove.

Furthermore, the number of the clamping blocks is at least one, and the number of the clamping grooves corresponds to the number of the clamping blocks.

Compared with the prior art, the beneficial effects of this application are:

1. this application can effectively improve the location efficiency in handlebar and the front fork assembling process through the cooperation structure that increases fixture block and draw-in groove.

2. This application is through the cooperation structure that increases fixture block and draw-in groove, can effectively avoid screwing up the produced stress concentration phenomenon of inclined nut through tie bolt, improves the life at handlebar and front fork connection position.

3. This application can improve on original vehicle structure, helps reducing the quantity of the required spare part of handlebar and front fork cooperation, reduces packing volume, reduction in production cost.

In the figure: 1. a handlebar; 2. a handlebar stem; 3. a clamping block; 4. a card slot; 5. a front fork riser; 6. a front fork; 7. a tilt nut; 8. and tightening the bolts.

Detailed Description

The technical solutions described in the present application are further described below with reference to the accompanying drawings and embodiments. It should be noted that the following paragraphs may refer to terms of orientation including, but not limited to, "upper, lower, left, right, front, rear", etc., which are based on the orientation shown in the drawings corresponding to the specification, and should not be construed as limiting the scope or technical solutions of the present application, but merely as facilitating better understanding of the technical solutions described in the present application by those skilled in the art.

Example 1: a handlebar and front fork positioning device comprises a handlebar 1 and a front fork 6, wherein a clamping block 3 is arranged on a handlebar vertical pipe 2 in the handlebar 1, a clamping groove 4 corresponding to the clamping block 3 in shape and position is processed on a front fork vertical pipe 5 in the front fork 6, and the clamping block 3 is positioned in the clamping groove 4 after the handlebar vertical pipe 2 is inserted into the front fork vertical pipe 5.

Example 2: the utility model provides a handlebar and front fork positioner, wherein fixture block 3 is two and distributes in the both sides of handlebar riser 2, and draw-in groove 4 is two and sets up corresponding to the position of fixture block 3. The structures and the connection relations of the rest parts are the same as those described in any of the previous embodiments.

On the basis of the above-mentioned embodiments, the present application continues to describe the technical features and functions of the technical features mentioned therein in detail to help those skilled in the art to fully understand the technical solutions of the present application and reproduce the same.

An object of this application is to provide a novel location structure of handlebar and front fork, it is adapted to new production or structurally improves at present electric motor car. Specifically, a ring body with a clamping block 3 is fixed on the outer surface of the handlebar stem 2, a clamping groove 4 is processed on the upper end surface of the front fork stem 5, and the position and the shape of the clamping groove 4 are matched with the position and the shape of the clamping block 3, so that the clamping block 3 can be clamped in the clamping groove 4, and the clamping block 3 is prevented from rotating around the handlebar stem 2 in the circumferential direction.

During the assembly process, the handlebar stem 2 is inserted into the front fork stem 5, the clamping block 3 enters the clamping groove 4 during the insertion process of the handlebar stem 2, and the matching posture of the handlebar 1 and the front fork 6 meets the installation requirement. An operator drives the tensioning bolt 8 to rotate through a handheld tool, the tensioning bolt 8 drives the inclined nut 7 located inside the handlebar vertical pipe 2 to rotate, the handlebar vertical pipe 2 is tensioned towards the front fork vertical pipe 6 in the rotating process of the inclined nut 7, and due to the existence of the clamping block 3 and the clamping groove 4, part of stress can be reduced at the connecting part, so that the damage of the connecting part caused by overlarge stress is avoided.
