Description

Technical Field

[0001] This utility model relates to the technical field of parking structure for two-wheeled vehicles, and in particular to a two-wheeled vehicle and its adaptive single-support parking structure. Background Technology

[0002] Bicycles have always been the most widely used mode of transportation for short-distance travel in people's daily lives. In recent years, with the rapid popularization of public bicycles and shared bicycles, the variety of bicycles and the development of the industry have been further enriched.

[0003] As bicycles are used in public places, their performance requirements differ from those of traditional bicycles. Traditional bicycles are usually parked in relatively flat locations, but for public bicycles, the habit of stopping and going immediately has become a necessity. Therefore, it is particularly important to improve the convenience and stability of parking by using single-support parking racks that can adapt to different parking locations.

[0004] In related technologies, the existing single-support parking racks have an angle of contact with the ground that cannot be adjusted. When the parking position is uneven, there is a risk of the vehicle tipping over. After the vehicle tipps over, the maintenance personnel have to readjust it, which increases their workload. Frequent tipping also accelerates vehicle damage. Utility Model Content

[0005] In response to the shortcomings of the existing production technology, the applicant provides a two-wheeled vehicle with a reasonable structure and its adaptive single-stance parking structure. When parking, the single-stance component automatically adjusts the parking angle according to the ground conditions to improve vehicle stability.

[0006] The technical solution adopted in this utility model is as follows: An adaptive single-stand parking structure includes a parking module, wherein an angle adjustment module is provided between the parking module and the vehicle body. The parking module includes a pivot bracket and a support rod that rotates around the pivot bracket. The angle adjustment module includes: The lower fixing plate is fixedly connected to the rotating shaft bracket. The upper fixing plate is stacked on the lower fixing plate. The angle between the plane where the upper fixing piece is located and the plane where the lower fixing piece is located is adjustable.

[0007] As a further improvement to the above technical solution: The relative position of the upper fixing plate is constant, and the lower fixing plate swings with the upper fixing plate as the motion reference.

[0008] The ground reaction force experienced by the parking module when the vehicle is parked is the power source for the lower fixed plate to swing.

[0009] A rotatable connection structure is provided between the upper fixing plate and the lower fixing plate. The rotatable connection structure adopts an elastic element or an arc-shaped rotating pair.

[0010] When the upper fixing piece and the lower fixing piece are connected by an elastic element, the elastic element is initially filled between the upper fixing piece and the lower fixing piece, and the elastic element has a compressibility deformation in the circumferential direction.

[0011] The elastic element is a compression spring or a torsion spring.

[0012] When the upper fixing plate and the lower fixing plate are connected by an arc-shaped rotating joint, the upper fixing plate is formed with an upper arc surface and the lower fixing plate is formed with a lower arc surface. The upper arc surface and the lower arc surface overlap and are penetrated by a mounting bolt. A support spring is fitted onto the mounting bolt, and the support spring is located between the upper arc surface and the lower arc surface.

[0013] A universal joint is also connected between the upper fixing plate and the lower fixing plate.

[0014] The upper fixing plate bends towards the lower fixing plate on both sides to form a limiting flange, which restricts the movement of the lower fixing plate; the lower fixing plate can only swing relative to the upper fixing plate.

[0015] A two-wheeled vehicle with the aforementioned adaptive single-stance parking structure, wherein the upper fixing plate is fixedly connected to the body of the two-wheeled vehicle.

[0016] The beneficial effects of this utility model are as follows: 1. The support rod is fixed to the vehicle by a rotating structure consisting of an upper and lower fixing plate. When parking, the angle of the support rod adaptively stops at the optimal angle in the front-rear direction with the rotation structure of the upper and lower fixing plates, ensuring the stability of the vehicle. The part of the support rod that touches the ground, that is, the bottom plate of the support rod that rests on the ground, is in the position of maximum contact with the ground.

[0017] 2. When retracted, the limiting structure formed by the left and right flanges of the upper fixing plate will not cause left and right swaying. Its parking operation is not affected by direction and has the same function as a conventional single-support parking rack.

[0018] 3. The overall structure of this utility model is relatively simple, and the added angle adjustment module does not require extensive adjustments to the frame and the entire vehicle structure. Attached Figure Description

[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0027] Example 1: This embodiment addresses the problem in the prior art where, when a shared bicycle's single support rod 1 is parked, the angle between it and the bicycle body is fixed, and when parked on uneven ground, the bicycle's own weight does not fully act on the support rod 1, leading to instability and tipping over. It proposes a single support structure where the angle between the support rod 1 and the bicycle body adjusts according to the road conditions.

[0028] like Figure 2 The diagram shown is a schematic representation of the single-support structure in the parking state of this embodiment. Figure 3 This is a schematic diagram of the single-support structure in the driving state of this embodiment.

[0029] Single-braced structure such as Figure 1 As shown, it is divided into a parking module and an angle adjustment module.

[0030] The parking module is a conventional single-support structure, and this embodiment makes almost no modifications or limitations to the parking module.

[0031] The parking module includes a pivot bracket 4, on which a support shaft 2 is supported and rotatably connected to a support rod 1. (Refer to reference...) Figure 5 A support limiting spring 3 is installed between the support rod 1 and the rotating shaft bracket 4.

[0032] The main improvement in this embodiment is that the original pivot bracket 4, which was installed on the vehicle body, is replaced by an angle adjustment module added between the pivot bracket 4 and the vehicle body.

[0033] The angle adjustment module includes a lower fixing plate 7 and an upper fixing plate 9. The lower fixing plate 7 is fixedly connected to the rotating shaft bracket 4. The lower fixing plate 7 and the rotating shaft bracket 4 can be connected by welding or by fastening.

[0034] The upper fixing plate 9 is connected to the vehicle body, and the upper fixing plate 9 and the vehicle body can also be connected by welding or fastening. The vehicle structure is not shown in this embodiment to prevent the single-support structure from being too small in scale and difficult to read.

[0035] The upper fixing plate 9 and the lower fixing plate 7 can rotate relative to each other. The length direction of the upper fixing plate 9 and the lower fixing plate 7 is the x-direction, limiting the y-direction and z-direction. For example... Figure 1 As shown, the relative rotation between the upper fixed plate 9 and the lower fixed plate 7 is essentially the change in angle between the upper fixed plate 9 and the lower fixed plate 7, which is based on the upper fixed plate 9 and rotates around the y-direction.

[0036] Specifically, this manifests as follows: When the vehicle is parked, if the ground is uneven, the support rod 1 is initially insufficient to support the vehicle's weight. At this time, the end of the support rod 1 that is in contact with the ground will slide away from the vehicle along the x-direction, which means that the angle between the support rod 1 and the vehicle becomes larger, providing more stable support for the vehicle.

[0037] An upper arc surface 901 is formed on the upper fixing plate 9, and a lower arc surface 701 is formed on the lower fixing plate 7. The upper arc surface 901 and the lower arc surface 701 are stacked. A universal fixing shaft 6 is connected through the upper arc surface 901 and the lower arc surface 701. When relative displacement occurs between the upper arc surface 901 and the lower arc surface 701, it is not affected by the universal fixing shaft 6.

[0038] A support spring 8 is fitted onto the universal fixed shaft 6. The support spring 8 is clamped between the upper arc surface 901 and the lower arc surface 701 to compensate for the gap between the two, making the angle adjustment action more stable and less prone to slippage.

[0039] The universal fixed shaft 6 is tightened and limited by nut 10.

[0040] A single-support mounting bolt 5 is also connected between the upper fixing plate 9 and the lower fixing plate 7. The function of the single-support mounting bolt 5 is to provide a connection reference for the upper fixing plate 9 and the lower fixing plate 7. The single-support mounting bolt 5 is fastened to the upper fixing plate 9, and is connected to the lower fixing plate 7 through a larger through hole. The single-support mounting bolt 5 does not limit the movement of the lower fixing plate 7, but only supports the lower fixing plate 7 by means of the bolt head to allow the lower fixing plate 7 to move.

[0041] On both sides of the upper fixed piece 9 in the y direction, there are limiting flanges 902. The limiting flanges 902 limit the lower fixed piece 7 in the y direction, so that the lower fixed piece 7 can only rotate in the y direction. This means that the parking module can be adjusted up and down in the z direction, which causes the contact point between the support rod 1 and the ground to change.

[0042] Example 2: As a further limitation of Embodiment 1, the protruding direction of the upper arc surface 901 is the side away from the ground in the z-direction; the protruding direction of the lower arc surface 701 is the side away from the ground in the z-direction.

[0043] As an alternative implementation, the protruding direction of the upper arc surface 901 is towards the ground in the z-direction; the protruding direction of the lower arc surface 701 is towards the ground in the z-direction.

[0044] In other words, theoretically, as long as the upper arc surface 901 and the lower arc surface 701 are nested together and can rotate relative to each other, the relative rotation between the upper fixed piece 9 and the lower fixed piece 7 can be achieved.

[0045] Example 3: At least two single-support fixed shafts are provided between the upper fixed plate 9 and the lower fixed plate 7. The single-support fixed shafts are arranged along the x-direction.

[0046] Example 4: As a further limitation of Embodiment 1, the lower arc surface 701 faces the upper arc surface 901, and its top is set as a flat plane. The flat plane can provide more stable support for the supporting spring 8.

[0047] Example 5: As an alternative to Embodiment 1, both the upper fixing plate 9 and the lower fixing plate 7 can be flat plates without protruding curved surfaces. One or more elastic elements 11 can be directly connected between the upper fixing plate 9 and the lower fixing plate 7. The elastic element 11 can be a compression spring or a torsion spring.

[0048] The working principle of this embodiment is: under the action of external force, the deformation of one side of one elastic element 11, or the deformation of several elastic elements 11, can also present a state of change in the relative position between the lower fixed piece 7 and the upper fixed piece 9, and can also drive the support rod 1 to move on the ground.

[0049] The advantage of this invention is that it adds a simple angle adjustment module, which allows the angle between the support rod 1 and the vehicle body to increase when the vehicle is parked, thereby improving the stability of the support.

[0050] 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.
