Description

Technical Field

[0001] The utility model relates to the technical field of off-road motorcycles, in particular to an off-road motorcycle with high passability. Background Art

[0002] An off-road motorcycle, also known as a non-road two-wheeled motorcycle, is a type of motorcycle used in a closed off-road circuit for motorcycle sports or all-terrain vehicle racing. Because it can ride on harsh ground environments such as sand, mud, river beaches, mountains, and even rock areas, when riding, the movement of the rear wheel brings mud and water splashing onto the structure of the whole vehicle. Therefore, there are off-road motorcycles with mudguard functions on the market.

[0003] For example, in the Chinese utility model patent "Integrated Functional Off-Road Motorcycle Battery Box" with the patent publication number CN221188891U, it includes a frame, a battery box is installed on the frame, a battery is arranged in the battery box, an electrical component fixing bracket is arranged on the side surface of the battery box, a mudguard fixing bracket is arranged at the bottom of the battery box, and a rear mudguard is installed on the mudguard fixing bracket.

[0004] In the above solution, only the upper end of the mudguard is fixed on the bracket. To avoid interference between the mudguard and the rear wheel of the off-road vehicle, the lower end is not fixed, and the structure is unstable. When driving on a road with harsh environment, more mud and water splashed by the rear wheel of the motorcycle will cause the mudguard to deform, resulting in poor mudguard effect. Summary of the Utility Model

[0005] Aiming at the problem of unstable structure of the mudguard of the off-road motorcycle, the technical problem to be solved by the utility model is to provide an off-road motorcycle with high passability.

[0006] The technical solution adopted by the utility model to solve the above technical problems is as follows: An off-road motorcycle with high passability includes a frame and a swing frame. The swing frame is rotatably connected to the frame, and a rear wheel assembly is arranged on the swing frame. The frame includes a mounting frame for installing a driving mechanism and a cross frame for installing a seat plate. The mounting frame is fixedly connected to the cross frame and the mounting frame is located below the cross frame. It also includes two support rods inclined upward along the tail end of the cross frame. The two ends of the two support rods are respectively fixed on the mounting frame and the cross frame, and the two support rods are respectively located on the left and right sides of the mounting frame and the cross frame. A mudguard is fixedly arranged on the two support rods. The upper end of the mudguard wraps the tail of the cross frame, and there is a gap between the lower end of the mudguard and the mounting frame to form an avoidance opening. A shock absorber is hinged on the swing frame and passes through the avoidance opening and is hinged to the mounting frame. When the off-road motorcycle is running, the mud and water are blocked by the mudguard and slide down along the mudguard and flow out from the lower end of the shock absorber. When the road section is rough, the shock absorber cooperates with the swing frame to swing in the avoidance opening so that the swing of the rear wheel assembly is not restricted.

[0007] A further preferred solution of the present utility model is as follows: The cross frame has a mounting portion extending out of the upper end of the support rod. The mudguard includes a first inclined section, a second inclined section, and a third inclined section. The first inclined end is fixedly connected to the support rod. The second inclined section is connected to and fixedly connected to the bottom of the mounting portion at the upper end of the first inclined end. The third inclined section is connected to the rear end of the second inclined section to wrap the end of the cross frame and is fixedly connected to the end housing of the seat plate.

[0008] A further preferred solution of the present utility model is as follows: The first inclined section, the second inclined section, and the third inclined section are integrally formed.

[0009] A further preferred solution of the present utility model is as follows: There are flanges on both sides of the first inclined section and the second inclined section. When the first inclined section is fixed to the support rod and the second inclined section is fixed to the mounting portion, the first inclined section and the second inclined section respectively wrap the upper side of the support rod and the mounting portion inside.

[0010] A further preferred solution of the present utility model is as follows: The first inclined section has a diversion groove recessed inward.

[0011] A further preferred solution of the present utility model is as follows: The width of the diversion groove gradually becomes wider from top to bottom.

[0012] A further preferred solution of the present utility model is as follows: Both sides of the first inclined section gradually incline inward into the diversion groove.

[0013] A further preferred solution of the present utility model is as follows: The cross frame gradually inclines upward from the front end to the rear end, and the slope of the second inclined section is equal to the slope of the cross frame.

[0014] A further preferred solution of the present utility model is as follows: The support rod, the mounting frame, the cross frame, and the swing frame form a swing space, and the swing frame can swing within the swing space.

[0015] A further preferred solution of the present utility model is as follows: The front end of the vehicle frame is rotatably connected with a front wheel assembly, and the front wheel of the front wheel assembly has a diameter larger than the diameter of the rear wheel of the rear wheel assembly.

[0016] Compared with the prior art, the present utility model has the following advantages:

[0017] 1. By fixedly providing two support rods between the mounting frame and the cross frame, and fixedly providing a mudguard on the two support rods, the upper end of the mudguard wraps the tail of the cross frame. When the off-road motorcycle is running, the mud and water are blocked by the mudguard and slide down along the mudguard and flow out from the lower end of the shock absorber. The mudguard is fixed on the two support rods, with a stable structure and strong impact resistance. When the off-road motorcycle runs in a harsh environment, the mud, sand, and stones thrown out by the rear wheel are not easy to deform it, improving the mudguarding effect of the off-road motorcycle.

[0018] 2. A spacing is provided between the lower end of the mudguard and the mounting bracket to form an avoidance opening. A shock absorber is hinged on the swing bracket and passes through the avoidance opening to be hinged with the mounting bracket. When the road section is rough, the shock absorber cooperates with the swing bracket to swing within the avoidance opening, so that the swing of the rear wheel assembly is not restricted by the mudguard, making the swing range of the rear wheel assembly and the swing bracket larger, which helps to improve the passability of the off-road motorcycle.

[0027] The preferred embodiments of the present invention will be described in detail below with reference to the drawings. Those skilled in the art will understand that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present invention.

[0028] It should be noted that like reference numerals denote like elements in the following figures, and thus, once an element is defined in one figure, it may not be further defined or explained in subsequent figures.

[0029] This embodiment mainly elaborates on a cross - country motorcycle with high passability, as follows:

[0030] As Figures 1 to 6 shown, a cross - country motorcycle with high passability includes a frame 1, a swing frame 2, and two support rods 4. The swing frame 2 is rotatably connected to the frame 1. When the cross - country motorcycle travels on a rough road, the swing frame 2 can rotate relative to the frame 1 to adapt to the rough section. A rear - wheel assembly 3 is provided on the swing frame 2. The frame 1 includes a mounting bracket 11 for mounting a drive mechanism 8 and a cross - frame 12 for mounting a seat plate 9. The mounting bracket 11 is fixedly connected to the cross - frame 12 and the mounting bracket 11 is located below the cross - frame 12. The fixed connection method can be welding or integrally formed. For the convenience of production, welding is preferably used. The two support rods 4 are arranged obliquely upward along the tail end of the cross - frame 12. The two ends of the two support rods 4 are respectively fixed on the mounting bracket 11 and the cross - frame 12, and the two support rods 4 are respectively located on the left and right sides of the mounting bracket 11 and the cross - frame 12. A mudguard 5 is fixedly provided on the two support rods 4. The upper end of the mudguard 5 wraps the tail of the cross - frame 12. Specifically, the mudguard 5 is provided with connection holes, and the support rods 4 and the tail of the cross - frame 12 are provided with threaded holes corresponding to the connection holes. Screws pass through the connection holes and extend into the threaded holes to cooperate with the threaded holes to fix the mudguard 5. The fixing structure of the mudguard 5 is stable and has strong impact resistance. When the cross - country motorcycle travels in a harsh environment, the mud, sand, and gravel thrown out by the rear wheel 31 are not easily deformed. There is a gap between the lower end of the mudguard 5 and the mounting bracket 11 to form an avoidance opening 6. A shock absorber 7 is hinged on the swing frame 2 and passes through the avoidance opening 6 to be hinged with the mounting bracket 11. When the cross - country motorcycle travels, under the swing of the rear - wheel assembly 3, the mud, sand, and gravel thrown out by the rear - wheel assembly 3 and the rear wheel 31 are blocked by the mudguard 5 and slide down along the mudguard 5 and flow out from the lower end of the shock absorber 7. When the road section is rough, the shock absorber 7 cooperates with the swing frame 2 to swing in the avoidance opening 6 so that the swing of the rear - wheel assembly 3 is not restricted, thereby making the swing range larger and helping to improve the passability of the cross - country motorcycle.

[0031] As Figure 4 、 Figure 5 and Figure 6As shown in the figure, the cross frame 12 has a mounting portion 121 extending out of the upper end of the support rod 4. The fender 5 includes a first inclined section 51, a second inclined section 52, and a third inclined section 53. The first inclined end is fixedly connected to the support rod 4. The second inclined section 52 is connected to and fixedly connected to the bottom of the mounting portion 121 at the upper end of the first inclined end. The third inclined section 53 is connected to the rear end of the second inclined section 52 to wrap the end of the cross frame 12 and is fixedly connected to the end housing of the seat plate 9. The settings of the first inclined section 51, the second inclined section 52, and the third inclined section 53 of the fender 5 can protect the cross frame 12, and then the tail, the bottom, and the mounting frame 11. When mud, water, sand, and gravel splash along the rear wheel 31 of the rear wheel assembly 3, the mud, water, sand, and gravel splash onto the third inclined section 53 and the second inclined section 52 and then slide out along the first inclined section 51, avoiding the situation that when the off-road motorcycle travels on a rough cement road, the mud, sand, and gravel splash onto the vehicle body and need to be cleaned every time, which is rather troublesome. And long-term cleaning will cause the metal of the frame 1 to rust and shorten the service life of the off-road motorcycle.

[0032] Specifically, to further improve the strength of the fender 5, the first inclined section 51, the second inclined section 52, and the third inclined section 53 are integrally formed, and at the same time, it can be avoided that the mud and water are sprayed on the frame 1 from the gap due to the gap at the connection of each inclined section.

[0033] As Figure 6 shown, there are flanges 54 on both sides of the first inclined section 51 and the second inclined section 52. When the first inclined section 51 is fixed on the support rod 4 and the second inclined section 52 is fixed on the mounting portion 121, the first inclined section 51 and the second inclined section 52 respectively wrap the upper side of the support rod 4 and the mounting portion 121 inside, which can avoid some mud, water, sand, and gravel from being sprayed onto the frame 1 through the side gaps of the fender 5 and improve the effect of the fender 5 in blocking mud, water, sand, and gravel.

[0034] As Figure 3 、 Figure 4 and Figure 6 shown, the first inclined section 51 has a diversion groove 55 that is recessed inward. The diversion groove 55 has a guiding function. When the mud and water flow from the third inclined section 53 and the second inclined section 52 to the first inclined section 51, under the action of the diversion groove 55, the mud and water gather in the diversion groove 55 and slide along the diversion groove 55. Because the mud and water reach the first inclined section 51 and there is more mud and water towards the bottom, in order to improve the diversion effect and avoid the mud and water in the diversion groove 55 from overflowing the diversion groove 55, the width of the diversion groove 55 gradually becomes wider from top to bottom, and the two sides of the first inclined section 51 gradually incline inward into the diversion groove 55. When the mud and water splash onto the first inclined section 51, because the terrain is lower towards the direction of the diversion groove 55, the mud and water can be introduced into the diversion groove 55.

[0035] Specifically, the cross-frame 12 gradually slopes upward from the front end to the rear end. The slope of the second inclined section 52 is equal to that of the cross-frame 12. The inclined setting of the cross-frame 12 can provide a relatively large space under the mounting portion 121 for the swing frame 2 and the rear wheel assembly 3 to swing so as to adapt to road conditions in different environments. The support rod 4, the mounting frame 11, the cross-frame 12 and the swing frame 2 form a swing space, and the swing frame 2 can swing within the swing space.

[0036] As Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, the front end of the vehicle frame 1 is rotatably connected to a front wheel assembly 10. The diameter of the front wheel 101 of the front wheel assembly 10 is larger than the diameter of the rear wheel 31 of the rear wheel assembly 3. The relatively small size of the rear wheel 31 compared to the front wheel 101 can further increase the swing space of the rear wheel 31 and the swing frame 2, thereby increasing the swing amplitude of the swing frame 2 and the rear wheel assembly 3, and thus improving the passability of the off-road motorcycle.

[0037] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present invention is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
