Abstract
Description
Technical Field
[0001] This utility model relates to the field of folding component technology, specifically a two-wheeled skateboard folding component. Background Technology
[0002] Currently, most two-wheeled skateboards on the market use folding structures made primarily of iron and aluminum components.
[0003] In terms of materials, it is not very safe for children, and the edges are easily scratched. In terms of structure, in order to ensure the stability of folding, the strength of the folding joints can only be increased, which directly leads to the problem that children are not strong enough to turn the folding handle.
[0004] Technically speaking, since iron and aluminum parts are mainly produced by stamping, the quality of finished products can be inconsistent in some areas where welding nodes are manually controlled.
[0005] To better control the standards of iron and aluminum parts, more manpower and effort must be invested in controlling the yield rate, resulting in a serious waste of resources in terms of materials and labor. Therefore, a two-wheeled skateboard folding component is needed to solve the above problems. Utility Model Content
[0006] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a two-wheeled skateboard folding assembly, so as to solve the problem that the two-wheeled skateboard folding structures proposed in the background art are mainly made of iron and aluminum parts. From the perspective of materials, they are not very safe for children. From the perspective of technology, since iron and aluminum parts are mainly stamped, the finished products are prone to inconsistent quality.
[0007] This utility model provides the following technical solution: a two-wheeled skateboard folding assembly, including a rotating mechanism, wherein the rotating mechanism includes a first ring and a second ring that are respectively connected to the upright part of the vehicle body and the bottom plate part;
[0008] The midpoints of the first ring and the second ring are on the same Y-axis;
[0009] It also includes a positioning mechanism, which includes an insertion cavity formed on the first ring member, and a locking member that moves up and down is inserted into the insertion cavity;
[0010] In addition, two symmetrical movable grooves are opened on the second ring along the rotation trajectory of the first ring, and the ends of the movable grooves extend out of the insertion cavity towards the locking member to form a locking area.
[0011] The locking component is provided with a symmetrical iron shaft that passes through the first ring component and extends into the movable groove rail for sliding.
[0012] To achieve the above technical solution, two iron shafts move in corresponding movable rails to achieve the rotation of the first and second ring components and the folding of the vehicle body. The movable rails have locking areas, and the locking components drive the iron shafts to move up and down to the locking areas, thereby forming a locking position in the fully unfolded and fully folded states, forming a folding unlock.
[0013] As a further improvement to this utility model, the first ring, the second ring, and the locking member are all made of plastic.
[0014] To achieve the above technical solution, the plastic is mainly injection molded, which makes it easy to accurately control the treatment of edges and gaps, thus greatly improving the safety factor.
[0015] As a further improvement to this utility model, a gap is reserved in the middle of the second ring for placing the first ring, forming a sandwich shape, and the outer diameters of the first ring and the second ring are the same.
[0016] The above technical solution improves the rotational stability between the first ring and the second ring.
[0017] As a further improvement to this utility model, a stamped iron sheet is bolted to the outer side of the second ring.
[0018] The above technical solution improves the overall strength of the second ring component.
[0019] As a further improvement to this utility model, the outer side of the stamped iron sheet is provided with a cover that completely covers the side of the second ring.
[0020] The above technical solution prevents foreign objects from entering the moving track and improves the protection of the rotating area.
[0021] As a further improvement to this utility model, a spring is inserted into the cavity so that the iron shaft is in a lifted state when it is located in the non-locking area of the movable groove rail.
[0022] The above technical solution makes it less likely for the iron shaft to accidentally come out when it is in the locking area.
[0023] As a further improvement to this utility model, the inner wall of the insertion cavity is provided with a protrusion that is in contact with the surface of the outer ring or the inner ring of the spring.
[0024] The above technical solution achieves the limiting effect of the spring.
[0025] As a further improvement to this utility model, the locking component has a through hole for the iron shaft to pass through.
[0026] Implementing the above technical solution facilitates the maintenance, replacement, and overall disassembly of the locking components.
[0027] The technical effects and advantages of this utility model are as follows:
[0028] 1. This utility model uses two iron shafts that move in corresponding movable grooves to achieve the rotation of the first ring and the second ring, and the folding of the vehicle body.
[0029] 2. The movable rail of this utility model has a locking area and a locking component that drives the iron shaft to move up and down and move the iron shaft to the locking area, thereby forming a locking position in the fully unfolded state and the fully folded state, forming a folding unlock.

[0037] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0038] Example:
[0039] Referring to the accompanying drawings, this utility model provides a two-wheeled skateboard folding assembly, including a rotating mechanism 100. The rotating mechanism 100 includes a first ring 110 and a second ring 111 that are respectively connected to the upright part of the vehicle body and the bottom plate part.
[0040] The midpoints of the first ring 110 and the second ring 111 are on the same Y-axis. The first ring 110, the second ring 111 and the locking member 211 are all plastic components. The second ring 111 has a gap reserved in the middle for the placement of the first ring 110, forming a sandwich shape. The outer diameters of the first ring 110 and the second ring 111 are the same. The outer side of the second ring 111 is bolted to a stamped iron sheet 112. The outer side of the stamped iron sheet 112 is provided with a cover 113 that completely covers the side of the second ring 111.
[0041] It also includes a positioning mechanism 200, which includes an insertion cavity 210 opened on the first ring 110, and a locking member 211 that moves up and down is inserted into the insertion cavity 210.
[0042] In addition, two symmetrical movable grooves 213 are opened on the second ring 111 along the rotation trajectory of the first ring 110, and the end of the movable groove 213 extends out of the insertion cavity 210 towards the locking member 211 to form a locking area 214.
[0043] The locking component 211 is provided with a symmetrical iron shaft 212 that passes through the first ring component 110 and extends into the movable groove 213 for sliding. A spring 215 is placed inside the insertion cavity 210 so that the iron shaft 212 is in a lifted state when it is in the non-locking area 214 of the movable groove 213. The inner wall of the insertion cavity 210 is provided with a protrusion 216 that is in contact with the outer or inner ring surface of the spring 215. The locking component 211 is provided with a through hole for the iron shaft 212 to pass through.
[0044] When unfolded, the two iron shafts 212 are located in either of the locking areas 214 of the corresponding movable groove rail 213. With the lifting action of the spring 215 on the locking member 211, the first ring member 110 and the second ring member 111 cannot rotate, thus forming an unfolded positioning state.
[0045] When folding is required, press the locking piece 211, causing the spring 215 to deform under pressure and the iron shaft 212 to move from the locking area 214 to the arc-shaped part of the movable track 213. At this time, rotate the first ring piece 110 relative to the second ring piece 111, allowing the iron shaft 212 to move along the arc-shaped part of the movable track 213 until the iron shaft 212 moves to another locking area 214 of the movable track 213. At this time, the spring 215 releases its elastic potential energy, causing the locking piece 211 to rise and the iron shaft 212 to move back into the locking area 214, forming a folded positioning state.
