Description

Technical Field

[0001] The utility model relates to the technical field of motorcycles, in particular to a cushion core and a seat cushion for a racing motorcycle. Background Art

[0002] In professional motorcycle competitions, the body must bend sideways with the vehicle body when turning. The existing motorcycle seat cushions are made of leather, with a foam cushion core between the leather surface and the bottom plate. There is no connection between the leather surface and the cushion core, and the periphery of the leather surface is bonded to the bottom plate by glue. Since the leather surface is relatively smooth and has relatively low friction, and the leather is also stretchable, there will be sliding between the human body and the seat cushion when turning sideways at high speed, and the center of gravity of the human body will change, and there is even the possibility of sliding off the motorcycle. In order to prevent sliding, the speed of the motorcycle needs to be reduced, which affects the results of the competition. Utility Model Content

[0003] The utility model aims at solving the problem that the surface of the seat cushion of a current motorcycle is made of leather, which is relatively smooth and has low friction, and the leather has stretch lines, so that sliding may occur between the human body and the seat cushion during high-speed turns, resulting in a change in the center of gravity and thus slow turns. A cushion core and seat cushion for a racing motorcycle are provided.

[0004] In order to achieve the above-mentioned utility model purpose, the utility model provides the following technical solutions:

[0005] On the one hand, the present application provides a cushion core for racing motorcycles, including a main body, arc plates are provided on both sides of the main body, a plurality of first protrusions are provided on the surface of the main body, the main body and the arc plates are made of EVA material as a whole, and the main body is provided with connecting holes.

[0006] Existing EVA materials are generally used to produce toys, etc., and their main functions are lightness and anti-collision, similar to the anti-collision strips pasted on the corners of tables. The present application adopts EVA materials to produce the cushion core. The friction of the EVA material is greater than that of leather, and a first protrusion is provided to further prevent slipping, so that there is no need to set leather fabric on the cushion core. Therefore, when turning, even if the speed is relatively high, the human body's buttocks and the motorcycle will not slide, which will not affect the results of the game.

[0007] Preferably, the first protrusion is a sphere, a hexagon, a cube or a trapezoidal pyramid, and the protrusions can be spaced apart or close together. The tops of the first protrusions are preferably spaced apart, which can increase the contact area and provide a better anti-slip effect.

[0008] Preferably, a first wrinkle-removing hole is provided on the rear side of the arc plate close to the main body. Since the cushion core is made of EVA material, when a human body sits on it, the legs and buttocks squeeze the cushion core. In order to prevent wrinkles on the cushion core, a first wrinkle-removing hole is provided at the bottom of the cushion core.

[0009] Preferably, the width of the main body gradually increases from front to back, a connecting hole is provided at the rear of the main body, and a second wrinkle-removing hole is also provided on the rear side of the main body close to the connecting hole. The tail of the cushion core is also subjected to relatively large force, and a second wrinkle-removing hole is also provided to prevent wrinkles from being eliminated on the surface of the cushion core.

[0010] Preferably, a second protrusion is provided at the rear of the main body, the cushion core is soft, and the bottom plate is hard. After the cushion core is connected to the bottom plate, the second protrusion is provided to achieve a vibration reduction effect.

[0011] Preferably, the second protrusion is a cuboid or a cube, which increases the contact area between the second protrusion and the bottom plate and achieves a better vibration reduction effect.

[0012] Preferably, a groove is provided on the arc plate, and a third protrusion is provided on the body corresponding to the groove, and the groove is arc-shaped. The groove and the third protrusion facilitate the positioning of the cushion core and the bottom plate, and the third protrusion also plays a role in vibration reduction.

[0013] On the other hand, the present application also provides a seat cushion for a racing motorcycle, comprising the cushion core and the bottom plate as described above, wherein the cushion core and the bottom plate are connected by glue.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the utility model adopts EVA material to make the cushion core, and the entire cushion core is formed in one piece without additional processing, so there is no need to wrap a layer of leather on the cushion core. The friction of the cushion core is greater than that of leather, and it is not as stretchable as leather. The sliding between the buttocks and the cushion core is minimized when turning at high speed. The first wrinkle-eliminating hole and the second wrinkle-eliminating hole are arranged on the bottom of the cushion core to eliminate the wrinkles generated after the human body sits on the seat cushion. At the same time, the first protrusion and the third protrusion can play a vibration-reducing role, and the groove can make the bottom plate and the cushion core accurately positioned during assembly.

[0024] like Figure 1 and Figure 2 As shown, the present application provides a cushion core for racing motorcycles. The cushion core 10 of the present application can be used on general motorcycles, but is particularly suitable for racing motorcycles. The cushion core 10 includes a body 101, and arc plates 102 are provided on both sides of the body 101. The body 101 and the arc plates 102 are made of EVA material as a whole. EVA is ethylene-vinyl acetate copolymer. The existing EVA material is generally used to make children's toys, and is not used in the field of motorcycles. The body 101 is provided with a connecting hole 104, and the connecting hole 104 corresponds to the connecting hole 104 on the bottom plate 20.

[0025] The surface of the body 101 is provided with a plurality of first protrusions 103, which may be spherical, hexagonal, cube or trapezoidal prism. The purpose of the first protrusions 103 is to increase the friction between the buttocks and the cushion core 10, so the tops of the first protrusions 103 are preferably separated and not connected, and the first protrusions 103 are preferably spherical.

[0026] The width of the main body 101 gradually increases from front to back, and a connecting hole 104 is provided at the tail of the main body 101. The cushion core 10 made of EVA material has a certain resilience. When a human body sits on it, the arc plates on both sides are pressed toward the middle under the action of gravity, and wrinkles will appear on the inner side of the main body 101 after the force is applied. Therefore, a first wrinkle-removing hole 105 is provided on the side of the rear part of the arc plate 102 close to the main body 101, and a second wrinkle-removing hole 106 is also provided on the side of the rear part of the main body 101 close to the connecting hole 104.

[0027] The thickness of the connection between the arc plate 102 and the main body 101 is thicker than that of the edge of the arc plate 102, and wrinkles are more likely to appear at the intersection of the arc plate 102 and the main body 101. The rear part of the main body 101 is also the place where the buttocks are stressed and wrinkles are more likely to appear. Therefore, the first wrinkle-eliminating hole 105 and the second wrinkle-eliminating hole 106 are designed. When subjected to force, the first wrinkle-eliminating hole 105 and the second wrinkle-eliminating hole 106 can provide a certain compression space to avoid wrinkles. The first wrinkle-eliminating hole 105 can be arranged in one row, two rows or even multiple rows. If the holes of two adjacent rows of multiple rows are arranged at intervals, the wrinkle-eliminating effect is better.

[0028] The rear part of the body 101 is provided with a second protrusion 107, the main function of which is to reduce vibration. Although the cushion core 10 has a certain elasticity, the bottom plate 20 is relatively hard. The cushion core 10 and the bottom plate 20 are glued together, so in order to achieve a better gluing effect between the bottom plate 20 and the cushion core 10, the second protrusion 107 is preferably a cuboid or a cube.

[0029] The arc plate 102 is provided with a groove 108, and the body 101 is provided with a third protrusion 109 corresponding to the groove 108. The groove 108 is arc-shaped, and the bottom plate 20 is provided with a positioning hole corresponding to the groove 108. The shape of the bottom plate 20 matches the shape of the cushion core 10, so it is basically arc-shaped, and a groove 108 and a third protrusion 109 are provided here. The positioning hole is flat and can cooperate with the groove 108 to position it. The third protrusion 109 can not only play a role in positioning, but also play a role in vibration reduction.

[0030] On the other hand, the present application also provides a seat cushion for a racing motorcycle, comprising the cushion core 10 and the bottom plate 20 described above, wherein the cushion core 10 and the bottom plate 20 are connected by glue. The tail of the cushion core 10 is designed to be U-shaped, the bottom plate 20 is located inside the cushion core 10, is wrapped by the cushion core 10, and is connected to the frame of the motorcycle.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
