Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle connecting parts, in particular to an electric vehicle aluminum alloy body frame connecting part. Background Art

[0002] The steering column of an electric vehicle is also called the three-star column. It is a device that connects the handlebars, front shock absorbers and front wheels. It can play a good role in shock absorption and direction control. The steering column of an electric vehicle is generally composed of a steering column and a steering column connector.

[0003] When connecting the steering column to the traditional electric vehicle connector, the steering column needs to be inserted into the hole of the connector first, and then locked by using the thread on the steering column and the nut. However, this fixing method is prone to loosening when the handlebar is hit, and then the direction of the steering column is inconsistent with the actual driving direction, which is easy to affect the user's route judgment and increase the danger. In view of this, we propose an electric vehicle aluminum alloy body frame connector. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide an electric vehicle aluminum alloy body frame connector that can solve the problem that the steering column is easily deviated when subjected to impact.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric vehicle aluminum alloy body frame connector, comprising a connector body, an insertion groove is provided on the upper surface of the connector body, a steering column is slidably connected inside the insertion groove, a locking block is fixedly connected to the lower surface of the steering column, locking grooves are provided on the left and right side surfaces of the locking block, a guide block is fixedly connected to the lower surface of the locking block, a triangular guide groove is provided on the outer surface of the guide block, the lower side of the triangular guide groove extends out of the lower surface of the guide block, a locking knob is provided on the rear side surface of the connector body, a triangular guide block matched with the triangular guide groove is fixedly connected to the inner wall of the insertion groove, and a locking structure is provided on the locking knob.

[0006] Preferably, the locking structure comprises a worm, the front end of which rotates and penetrates into the interior of the connector body, the inner wall of the insertion groove is provided with a motion groove, and two second locking blocks are slidably connected inside the motion groove.

[0007] Preferably, the adjacent side surfaces of the two second locking blocks are matched with the left and right side surfaces of the locking block.

[0008] Preferably, adjacent side surfaces of two of the second locking blocks are respectively fixedly connected with third locking blocks, and the third locking blocks are adapted to the locking grooves.

[0009] Preferably, the rear side surfaces of the two second locking blocks are respectively fixedly connected with connecting plates, and the inner wall of the moving groove is rotatably connected with a bidirectional threaded rod.

[0010] Preferably, the two connecting plates are respectively threadedly sleeved on the outer surface of the bidirectional threaded rod, and the outer surface of the bidirectional threaded rod is sleeved with a worm gear.

[0011] Preferably, the outer surface of the worm wheel is meshingly connected with the worm, and a weight-reducing groove is provided on the lower surface of the connector body.

[0012] Preferably, two mounting holes are provided on the upper surface of the connector body, shock absorbing components are arranged inside the two mounting holes, and the lower sides of the two shock absorbing components extend out of the lower sides of the two mounting holes respectively.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) When the steering column of the electric vehicle aluminum alloy body frame connector needs to be installed, the steering column is aligned with the insertion slot and inserted, and then the direction of the steering column is calibrated by using the cooperation of the triangular guide slot and the triangular guide block. Then, the locking knob is rotated, and the locking knob drives the locking structure to cooperate with the locking block and the locking slot to lock the steering column. Through the above structure, when connecting the steering column to the connector body, there is no need to carry a nut to reduce the burden on the worker. At the same time, during installation, the steering column can be positioned with the help of the triangular guide slot and the triangular guide block. The cooperation of the locking structure and the locking block can also be used to avoid the problem of rotation of the steering column when it is subsequently impacted.

[0015] (2) In the aluminum alloy body frame connector of the electric vehicle, the worm gear synchronously drives the bidirectional threaded rod to rotate. Since the motion groove limits the motion trajectory of the two second locking blocks and the connecting plate, the bidirectional threaded rod will synchronously drive the two connecting plates to move in opposite directions after rotation, thereby driving the two second locking blocks to move. After the two second locking blocks move, they fit with the outer surface of the locking blocks, and allow the third locking block to enter the interior of the locking groove to complete the installation. The above structure can not only make installation more convenient, but also reduce the overall weight of the connector body by setting two weight-reducing grooves, thereby indirectly reducing energy efficiency to a certain extent.
