Description

Technical Field

[0001] This utility model relates to the field of two-wheeled vehicle seat technology, and in particular to a seat cover structure. Background Technology

[0002] With the strict implementation of the new national standard for electric vehicles and the plastic restriction order for electric two-wheelers, the plastic parts of the entire vehicle are strictly limited.

[0003] In previous technologies, the base plate of the seat cushion commonly used plastic parts, resulting in a large amount of plastic usage. Furthermore, the seat cushion cover was fixed to the base plate with nails, making subsequent replacement of the seat cushion cover cumbersome. After the nails were removed, the cover could not be reused, and the cover also had irreversible damage and gaps, which was not conducive to the reuse of resources. Utility Model Content

[0004] This application addresses the shortcomings of the existing production technology by providing a reasonably structured seat cushion skin structure. It uses a metal seat cushion base plate with pre-set fixing holes on the skin, allowing for pre-assembly between the skin and the base plate. The skin is then pressed together with pressure blocks, making the entire structure detachable. The disassembled components are undamaged and can be reused.

[0005] The technical solution adopted in this utility model is as follows: A seat cushion covering structure, with the direction the rider faces towards the seat cushion as the z-direction, defines the x and y directions. Includes pressure blocks, base plates, foam, and skin stacked in the z-direction. The skin has circumferentially oriented positioning holes, and the base plate has circumferentially oriented positioning hooks; the skin is stretched from the riding side in the z-direction toward the positioning hooks, and the positioning holes pass through the positioning hooks. The pressure block is pressed into the hook surface of the base plate and the skin from the z-direction away from the riding side.

[0006] As a further improvement to the above technical solution: The positioning hole and the positioning hook are in line contact or surface contact.

[0007] The length of the positioning hole in the circumferential direction of the skin is greater than or equal to the length of the positioning hook in the circumferential direction of the skin.

[0008] The positioning hole has at least one straight edge.

[0009] The positioning hole is a rectangular through hole or a semi-circular through hole.

[0010] The positioning hook extends from the inner wall of the base plate.

[0011] The hook head of the positioning hook bends towards the riding side in the z direction.

[0012] The positioning hook is an integral part formed by punching the side wall of the base plate inward.

[0013] The pressing block is a ring-shaped component or multiple independent blocks.

[0014] The pressure block is provided with a first mounting hole, and the base plate is provided with a second mounting hole coaxial with the first mounting hole. Fastening pins pass through the first mounting hole and the second mounting hole. The fastening pins pass through the pressure block and the base plate sequentially from one side of the pressure block along the z direction, while avoiding the skin.

[0015] The beneficial effects of this utility model are as follows: 1. By combining the skin pressing block with the base plate structural components, the skin is tightly fixed to the base plate using a pressing method. The specific principle is as follows: utilizing the skin's certain extensibility, positioning holes are made around the skin, and positioning hooks are made on the base plate. The opening of the skin is first placed on the positioning hooks to prevent lateral swaying and to shape it. Then, the pressing block is used to tightly press the skin around the base plate of the seat cushion to achieve the pressing effect.

[0016] 2. Because the seat cover's pressure block is fixed to the seat base plate with screws, it can be disassembled using ordinary power tools, making it reusable and easy to disassemble. Attached Figure Description

[0023] The components include: 1. Pressing block; 2. Base plate; 3. Foam; 4. Skin; 101. First mounting hole; 102. Avoidance recess; 201. Positioning hook; 202. Second mounting hole; 401, Positioning hole; 402, Straight edge. Detailed Implementation

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0025] Example 1: like Figure 1 The figure shown is an exploded view of the present invention, which shows the four main components of the present invention: pressure block 1, base plate 2, foam 3, and skin 4.

[0026] The base plate 2 serves as the installation reference, with the rider's sitting direction towards the seat as the z-direction, and the x and y directions defined.

[0027] Foam 3 is placed on the z-axis of the base plate 2, and skin 4 is covered on the outside of foam 3. The edge of skin 4 is pulled down to extend to the z-axis of the base plate 2 facing the ground, and the positioning hole 401 at the edge of skin 4 is hung on the positioning hook 201 of the base plate 2 to pre-tension skin 4.

[0028] Skin 4 has a certain deformation capacity. The conventional assembly method uses nails to fix skin 4 and base plate 2. This nailing method, under the premise that skin 4 has the ability to deform and recover, is equivalent to making a small hole in skin 4 and continuously applying tension to the small hole. This makes it easy for elongated elliptical holes to appear in skin 4. Every time you sit down, there is a tensile force on the small hole, that is, a small area with high pressure, which can easily cause large-area damage over time.

[0029] In this embodiment, as Figure 5 As shown, a positioning hole 401 is pre-drilled on the skin 4. The size of the positioning hole 401 is similar to that of the positioning hook 201. The positioning hole 401 has at least one straight edge 402, which can be regarded as a line contact with the positioning hook 201. Considering that the skin 4 also has a certain thickness, it can also be considered that the positioning hole 401 and the positioning hook 201 are in surface contact, and the contact surface is the wall thickness surface of the positioning hole 401.

[0030] As an alternative implementation, the positioning hole 401 can be a semi-circular or rectangular hole, as long as it can meet the surface contact condition with the positioning hook 201.

[0031] The positioning hook 201 is a component directly punched from the base plate 2. The base plate 2 has a bulge on the upward side in the z-direction, and the bulge surface is punched inward to obtain the desired shape. Figure 2 The positioning hook 201 is shown. The hook portion of the positioning hook 201 is bent towards the inner wall of the base plate 2.

[0032] After the positioning hole 401 of the skin 4 is hooked onto the positioning hook 201, the pressure block 1 is pressed onto the bottom plate 2. Fastening nails are used to penetrate the first mounting hole 101 and the second mounting hole 202 on the pressure block 1, so that the pressure block 1 is pressed tightly onto the skin 4, but the fastening nails will not penetrate the skin 4, causing damage to the skin 4.

[0033] The seat installation is now complete. If disassembly is required, remove the fastening pins to remove the pressure block 1 and the skin 4 from the positioning hook 201. After inspection, it can be reassembled and used.

[0034] Example 2: The base plate 2 can be made of metal or plastic. Both metal and plastic plates can be punched to form the positioning hook 201.

[0035] Example 3: The pressing block 1 can be made of metal or plastic.

[0036] The pressure block 1 can be a single pressure block 1 or an integral ring pressure block 1.

[0037] The advantage of a single pressure block 1 is that there is no stress between them. During the pressing process of each pressure block 1, it will not affect other pressure blocks 1. Due to its small size, the pressure block 1 also helps to reduce the weight of the whole vehicle. At the same time, damaged pressure blocks 1 are easy to repair and replace individually. The single pressure block 1 is pressed into the edge of the skin 4, and the clamping force applied to the skin 4 is multiple pressure points, which makes it easy to adjust the local clamping force.

[0038] The advantage of the annular pressure block 1 is that it can pre-compress the skin 4, generate uniform pressure on the entire periphery of the skin 4, and play an auxiliary positioning role.

[0039] The choice between a single pressing block 1 and a ring-shaped pressing block 1 can be made according to actual needs.

[0040] Example 4: At the edge of pressure block 1, such as Figure 3 As shown, a relief recess 102 is formed. The function of the relief recess 102 is to allow space for the positioning hook 201, as... Figure 6 As shown, since the positioning hook 201 extends to the inside of the base plate 2 and the pressure block 1 needs to be as close as possible to the edge of the skin 4, that is, the edge of the base plate 2, the positioning recess 102 is provided at the edge of the pressure block 1 to apply the largest possible pressing surface to the skin 4 without causing interference between the components, thereby improving the pressing reliability.

[0041] The main advantage of this invention is that the components are simply and detachably connected, and there is no damage to the product during assembly or disassembly. After disassembly, components that have not been worn out during use can be reused as repair parts, demonstrating the advantage of component reusability.

[0042] 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.
