Description

Technical Field

[0001] This utility model relates to a torsion spring for four-wheeled vehicles, specifically a torsion spring for four-wheeled vehicles. Background Technology

[0002] In the prior art, some foldable four-wheeled vehicles are usually equipped with torsion springs that facilitate the folding and unfolding of the four-wheeled vehicle. When folding, the torsion spring is compressed, and when unfolding, the restoring force of the torsion spring drives the folding parts on the four-wheeled vehicle to return to their original position. At the same time, the restoring force of the torsion spring itself forms an elastic compression on the folding parts, which plays a role in limiting the position of the folding parts.

[0003] In existing technology, when installing a torsion spring on a four-wheeled vehicle, a movable pin is attached to a support rod for mounting the torsion spring. The torsion spring is then movably mounted on the support rod, one end of the torsion spring is connected to the drive component, and the other end is fixed by drilling a hole in the support rod and inserting the other end of the torsion spring into the fixed hole to complete the installation. This method is cumbersome, and fixing the torsion spring by inserting one end into the fixed hole of the support rod can lead to the end inserted into the fixed hole potentially coming out when the torsion spring is compressed. Simply relying on inserting one end of the torsion spring into the fixed hole results in poor installation stability and insufficient support strength under stress, making it prone to deformation. Therefore, a torsion spring for four-wheeled vehicles is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a torsion spring for four-wheeled vehicles in order to solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a torsion spring for a four-wheeled vehicle, comprising a torsion spring body; characterized in that it includes a drive section disposed on the torsion spring body and a positioning support section that provides positioning support for the torsion spring body on the four-wheeled vehicle frame; both ends of the positioning support section are formed with positioning connection points for movably mounting the torsion spring body by winding; the end of the drive section is formed with a drive connection point that is movably connected to a component used to drive the torsion spring body when the four-wheeled vehicle is folded.

[0006] More preferably, the positioning support section is bent into a U-shape to fit the bracket on the four-wheeled vehicle.

[0007] More preferably, the two positioning connection points of the positioning support segment are on the same axis.

[0008] The beneficial effects of this utility model are as follows: By setting a drive section and a positioning support section on the torsion spring body, and forming positioning connection points for the pin shaft for movably mounting the torsion spring body on the four-wheeled vehicle by winding at both ends of the positioning support section, the two positioning connection points serve as connection points for connecting the pin shaft. The positioning support section between the two positioning connection points contacts the bracket on the four-wheeled vehicle to support the torsion spring body, which increases the overall force-bearing capacity and torsional resistance of the positioning support section, avoids easy deformation, and during installation, it is only necessary to place the positioning support section on the bracket for mounting the torsion spring and fit it against the bracket, without the need to drill holes in the bracket, making the installation simple and quick and the overall performance better.

[0013] The following description, in conjunction with the accompanying drawings, further illustrates a torsion spring for four-wheeled vehicles according to this utility model.

[0014] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0015] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] See Figure 1-3As shown, a torsion spring for a four-wheeled vehicle includes a torsion spring body 1; characterized in that it includes a drive section 2 disposed on the torsion spring body 1 and a positioning support section 3 that provides positioning support for the torsion spring body 1 on the four-wheeled vehicle frame; both ends of the positioning support section 3 are formed by winding to form positioning connection points 4 for movably mounting the torsion spring body 1; the end of the drive section 2 is formed by winding to form a drive connection point 5 that is movably connected to a component used to drive the torsion spring body 1 when the four-wheeled vehicle is folded.

[0017] The two positioning connection points 4 of the positioning support section 3 are on the same axis;

[0018] By setting a drive section 2 and a positioning support section 3 on the torsion spring body 1, and forming positioning connection points 4 at both ends of the positioning support section for movably mounting the torsion spring body 1 on the four-wheeled vehicle by winding, the two positioning connection points 4 serve as connection points for connecting the pin. The positioning support section 3 between the two positioning connection points 4 contacts the bracket on the four-wheeled vehicle to support the torsion spring body 1, which increases the overall force-bearing capacity and torsional resistance of the positioning support section 3, avoids easy deformation, and during installation, the positioning support section 3 only needs to be placed on the bracket for mounting the torsion spring and fit against the bracket, without the need to drill holes in the bracket. The installation is simple and quick and the overall performance is better.

[0019] The drive connection point 5 on the drive section 2 is movably connected to the component on the four-wheeled vehicle that drives the torsion spring when folding, so that the four-wheeled vehicle drives the drive section 2 to move when folding.

[0020] In one embodiment, the positioning support section 3 is bent into a U-shape to fit the bracket on the four-wheeled vehicle. The U-shape of the positioning support section 3 is to better fit the bracket and also to position it on the bracket, preventing displacement during installation or use.

[0021] During installation, the present invention is as follows: First, a connecting pin for movable installation of the torsion spring body 1 is installed on the bracket of the four-wheeled vehicle. Then, the two positioning connection points 4 on the torsion spring body 1 are fitted onto the two ends of the connecting pin and located on both sides of the bracket. During installation, the positioning support section 3 of the torsion spring body 1 is positioned above the bracket and is positioned on the bracket by means of the U-shaped shape. Finally, the drive connection point 5 on the drive end of the torsion spring body 1 is connected to the component for driving the torsion spring to complete the installation.

[0022] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
