Description

Technical Field

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

[0002] Off-road motorcycles are a type of motorcycle used in closed off-road circuits for motorcycle sports or all-terrain vehicle racing. Since riding is mostly done on complex roads, it is very easy to bump. When riding for a long time in hot weather, the buttocks are in close contact with the seat cushion, which is airtight and has poor heat dissipation. The surface of the seat cushion is generally made of leather and filled with sponge. When there is weight on the existing off-road motorcycle seat cushion, the sponge is compressed, resulting in wrinkles on the surface of the seat cushion. Existing off-road motorcycles also have relatively large wind resistance when driving. Utility Model Content

[0003] The utility model aims to solve the problems that the seat cushion of the current off-road motorcycle has poor heat dissipation effect and large wind resistance, and provides a seat cushion for an off-road motorcycle and an off-road motorcycle.

[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 seat cushion for an off-road motorcycle, including a base plate and a cushion core. The seat cushion has a length of L and a width of M, and a length-to-width ratio of :-:. The cushion core is provided with a heat dissipation groove, and the base plate is provided with openings corresponding to the heat dissipation groove.

[0006] The present invention controls the length-to-width ratio of the seat cushion to 1:3-1:5, so that the entire off-road motorcycle has a good streamline shape and can effectively reduce wind resistance. At the same time, a heat dissipation groove is arranged on the cushion core, and the cushion core can be cooled through the heat dissipation groove. At the same time, when a person sits on it, the seat cushion has an avoidance space to minimize wrinkles.

[0007] Preferably, the cross section of the heat sink is cylindrical, truncated cone or conical. It is best to set the heat sink in a truncated cone shape, which is most comfortable for people to sit on. The shape of the heat sink is preferably a truncated cone.

[0008] Preferably, the front end of the cushion core is provided with a first protrusion toward the bottom plate, the first protrusion is arranged along the length direction of the bottom plate, and the bottom plate is provided with a first groove corresponding to the first protrusion. The first protrusion is embedded in the first groove, so that the cushion core and the bottom plate are more firmly connected.

[0009] Preferably, the first protrusion is divided into two sections, and the first groove is also divided into two sections, so that the cushion core can be prevented from sliding relative to the bottom plate.

[0010] Preferably, both ends of the first groove are provided with openings, and connecting blocks are provided at the openings, and a U-shaped groove is provided on the connecting block, and a connecting groove is provided on the side of the bottom plate away from the first groove, and a strip-shaped connecting hole is provided in the connecting groove. The two sides of the bottom plate are connected through the U-shaped groove and the connecting hole, so that the position of the seat cushion can be easily adjusted.

[0011] Preferably, the cushion core is further provided with a second protrusion and a third protrusion along the length direction, and the bottom plate is provided with a second groove and a third groove corresponding to the second protrusion, and the third protrusion is triangular. The second and third protrusions mainly prevent the middle part of the cushion core connected to the bottom plate from shifting.

[0012] Preferably, a fourth protrusion is provided on the side of the cushion core away from the first protrusion, a fourth groove is provided at the bottom plate corresponding to the fourth protrusion, and the fourth protrusion is arranged along the width direction of the bottom plate. The fourth protrusion is in the opposite direction to the first protrusion, so that a limit is imposed in the length direction and an upper limit displacement is imposed in the width direction.

[0013] Preferably, a first reinforcing rib and a second reinforcing rib are provided on the bottom plate, one end of the first reinforcing rib is connected to the first groove, and the other end is connected to the fourth groove, and the first reinforcing rib is located on both sides of the bottom plate.

[0014] Preferably, a shock absorbing spring is installed in the heat dissipation groove, and the diameter of the opening is smaller than the diameter of the shock absorbing spring, so that the shock absorbing spring can increase comfort.

[0015] On the other hand, the present application also provides an off-road motorcycle, characterized in that it includes the seat cushion described above.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a heat dissipation groove in the cushion core, which can dissipate heat from the cushion on the one hand, and can remove wrinkles on the human body after the seat is seated on the cushion on the other hand. At the same time, a shock-absorbing spring can be installed in the heat dissipation groove to play a buffering role. The length-to-width ratio of the cushion is limited, so that the wind resistance of the off-road motorcycle is relatively small during driving. The cushion and the bottom plate are limited in both the horizontal and vertical directions through the cooperation of multiple protrusions and grooves, and the possibility of displacement is reduced.
