The central axis structure of traditional electric vehicles is usually more complicated, and the installation and disassembly process is cumbersome and time-consuming. In order to solve this problem, it is particularly important to develop a single-peak central axis quick-install structure for electric vehicles. This structure is designed to simplify the installation and disassembly process of the central axis, improve production efficiency and user maintenance convenience, while ensuring the stability and reliability of the central axis to meet the ever-changing needs of electric vehicles.

[0003] However, the existing single-peak center shaft quick-install structure for electric vehicles is difficult to solve the tolerance matching when installing center shafts of different diameters during use, and is prone to inaccurate positioning and uneven tightening force, which can easily damage the structure, increase work difficulty, and reduce the safety of electric vehicles when driving. Utility Model Content

[0004] The purpose of the utility model is to provide a single-peak center shaft quick-install structure for electric vehicles. By setting an expansion mechanism, the problem that the existing single-peak center shaft quick-install structure for electric vehicles is difficult to solve the tolerance matching problem when installing center shafts of different calibers during use, and is prone to inaccurate positioning and uneven tightening force, which can easily damage the structure, increase work difficulty, and reduce the safety of electric vehicles during driving is solved.

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

[0006] The utility model is a single-peak middle shaft quick-install structure for electric vehicles, comprising a single-peak shaft, on which an expansion mechanism and a fixing mechanism are provided;

[0007] The expansion mechanism includes a limit assembly and several sliding assemblies. The limit assembly includes a fixed shaft fixedly connected to the right side of the single-peak shaft. A connecting ring is fixedly connected to the outer wall of the fixed shaft, and a rotating block is rotatably connected to the inner wall of the connecting ring.

[0008] Furthermore, the sliding assembly includes a sliding groove 1 provided on the fixed shaft, and the rotating block is provided with an arc-shaped sliding groove.

[0009] Furthermore, a second slide groove is provided on the fixed shaft, the second slide groove is connected to the first slide groove, a sliding shaft is slidably connected on the inner wall of the first slide groove, and the sliding shaft is slidably connected in the arc-shaped slide groove.

[0010] Furthermore, a connecting plate is slidably connected to the inner wall of the second slide groove, a side of the connecting plate close to the sliding shaft is fixedly connected to the sliding shaft, and a side of the connecting plate away from the sliding shaft is fixedly connected to a support block.

[0011] Furthermore, the fixing mechanism includes a rotating assembly and a plurality of locking assemblies. The rotating assembly includes a telescopic rod fixedly connected to the right side of the rotating block. The right side of the telescopic rod is fixedly connected to a rotating cap.

[0012] Furthermore, a spring 1 is sleeved on the outer wall of the telescopic rod, the left side of the spring 1 is fixedly connected to the rotating block, the right side of the spring 1 is fixedly connected to the rotating cap, and the left side of the rotating cap and the right side of the rotating block are both fixedly connected with friction plates.

[0013] Furthermore, the locking assembly includes a sliding groove three provided on the connecting ring, a limiting plate is slidably connected to the inner wall of the sliding groove three, and a pull rod is fixedly connected to the right side of the limiting plate.

[0014] Furthermore, a spring 2 is sleeved on the outer wall of the pull rod, the left side of the spring 2 is fixedly connected to the limit plate, the right inner wall of the slide groove 3 is fixedly connected to the spring 2, and a buckle is rotatably connected to the outer wall of the pull rod.

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting up an expansion mechanism, the rotating assembly can be twisted. When the rotating assembly is twisted, it will drive the rotating block to rotate. When the rotating block rotates, it will drive several sliding shafts to move away from each other under the action of the arc-shaped slide groove, slide groove 1 and slide groove 2. When the several sliding shafts move away from each other, they will drive several supporting blocks to move away from each other through several connecting plates, thereby fixing the device in the center shaft of the electric vehicle. When facing the installation of center shafts of different diameters, it can well solve the tolerance matching, avoid inaccurate positioning and uneven tightening force, prevent damage to the structure, reduce work difficulty, and ensure the safety of the electric vehicle when driving;

[0017] 2. By setting up a fixing mechanism, the rotating cap can be pressed to move it to the left. When the rotating cap moves to the left, it will squeeze spring 1, causing it to elastically deform and generate elastic force. When the rotating cap moves to the left, it will drive the two friction plates closer to each other. When the two friction plates are in contact with each other, the pull rod can be pulled to cause spring 2 to elastically deform and generate elastic force. At this time, the buckle can be rotated to buckle the rotating cap. At this time, the rotating cap will squeeze the two friction plates against each other under the action of several locking components and two sets of elastic forces, thereby achieving fixation. When the structure is installed, the device will not reverse, preventing the device from falling off, ensuring vehicle driving safety, stabilizing vehicle performance, extending the service life of components, reducing wear, protecting the frame, and reducing noise.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
