Description

Technical Field

[0001] This utility model relates to the field of electric off-road motorcycle technology, specifically to an electric off-road motorcycle frame. Background Technology

[0002] As a mode of transportation that combines off-road performance with environmental friendliness, the frame of an electric off-road motorcycle is the core component that ensures the overall structural stability, safety, and driving performance.

[0003] However, in complex off-road scenarios, traditional frames often exhibit visible deformation due to insufficient structural strength or uneven stress distribution when faced with continuous bumps on unpaved roads and high-intensity impacts such as rock strikes. In severe cases, this can even lead to breakage. This not only instantly disrupts the vehicle's handling stability but also directly threatens the rider's safety, while significantly reducing the vehicle's durability and increasing maintenance costs and frequency.

[0004] Furthermore, during prolonged high-load off-road riding, electric motocross motorcycles generate significant heat due to the high-speed operation of the electric motor and the continuous discharge of the battery. Traditional frames often lack targeted heat dissipation channels, preventing the heat from being quickly conducted to the outside environment. This keeps the internal components of the frame and surrounding core components in a high-temperature environment for extended periods. This sustained high temperature accelerates the aging of the electric motor insulation and the degradation of the battery's active materials, leading to problems such as reduced power output and shorter driving range. Ultimately, this significantly shortens the lifespan of core components and diminishes the long-term value of the vehicle.

[0005] In view of the above, in order to overcome the above technical problems, this utility model designs an electric off-road motorcycle frame, which solves the above technical problems. Utility Model Content

[0006] The technical objective of this invention is to provide an electric off-road motorcycle frame to solve the problems of poor heat dissipation, insufficient structural stability, and inconvenient maintenance mentioned in the background art.

[0007] To achieve the above-mentioned technical objectives, this utility model provides the following technical solution: This utility model provides an electric off-road motorcycle frame, including a bracket, seat, handlebars, front suspension, front wheel, rear swingarm, rear suspension, and rear wheel. The seat is mounted on top of the bracket, which is an integrated load-bearing structure used to secure the various components and transmit force. The handlebars are mounted at the front end of the bracket, and the front suspension is mounted below the handlebars. The front suspension effectively cushions the bumps and impacts encountered by the front wheel during driving. The front wheel is mounted between the front suspension components, and the rear swingarm is mounted at the rear end of the bracket. The rear suspension is mounted above the rear swingarm, and the rear wheel is mounted between the right sides of the rear swingarm. The rear suspension and the rear swingarm work together to improve the vehicle's driving stability in complex road conditions.

[0008] Preferably, the bracket includes a head tube, side plates, a fixing plate, a connecting plate, and a main beam plate. The handle is equipped with a head tube, and two symmetrical side plates are fixedly installed on the sides of the head tube, providing support for the entire bracket. A fixing plate is fixedly installed at the rear end of each side plate to enhance the structural strength of the rear end of the side plate and facilitate the fixing of the side plate. One end of the connecting plate is installed on the head tube at the lower end of the two side plates, and the other end of the connecting plate is equipped with a main beam plate. The main beam plate has a U-shaped cross-section, and a radiator is fixedly installed inside the main beam plate. The main beam plate at the lower end of the radiator has heat dissipation holes, which are elongated in shape.

[0009] Preferably, an electric plate is installed at the lower end of the main beam plate. The electric plate has a V-shaped cross-section, and the angle of the V-shaped electric plate is set to an obtuse angle. The obtuse angle V-shaped design can disperse the vibration and driving impact when the electric motor is working. The electric plate is fixed to the side plate on both sides, which further enhances the stability of the electric motor installation. The electric motor is fixedly installed on the electric plate, and the electric plate is fixed to the side plate on both sides, which further enhances the connection between the electric plate and the bracket.

[0010] Preferably, a support plate is installed at the unclosed end of the U-shaped main beam plate. The cross-sectional shape of the support plate is L-shaped, with the long side of the support plate located on the main beam plate and the two sides of the short side of the support plate located between the two side plates. The L-shaped structure can provide support for both the main beam plate and the side plates at the same time, improving the overall structural stability of the support.

[0011] Preferably, a limiting plate is installed on the short side of the support plate, and the limiting plate is located between the two side plates. At the same time, a fixing plate is installed on the upper end of the limiting plate, and a hinge block for fixing the rear suspension is fixedly installed on the right side of the fixing plate. The hinge block provides a stable installation position for the rear suspension and ensures a reliable connection between the rear suspension and the vehicle frame.

[0012] Preferably, the battery is mounted on the support plate, and the battery on the support plate is located directly behind the heat sink. The heat sink can dissipate heat for the battery at the same time, preventing the battery from being affected by high temperature and thus its performance and lifespan. At the same time, this mounting position facilitates the installation and removal of the battery, making it convenient for future maintenance and replacement.

[0013] The beneficial effects of this utility model are as follows: 1. The radiator installed inside the main beam plate and the long strip-shaped heat dissipation hole at the bottom can quickly dissipate the heat generated by the motor, battery and other components during operation, effectively preventing the performance of the components from deteriorating due to high temperature and extending the service life of the components.

[0014] 2. The design of the obtuse-angle V-shaped electric plate, L-shaped support plate and limiting plate optimizes the stress structure of the frame, enhances the overall support strength and stability of the frame, and can better cope with bumps and impacts on off-road conditions, thus improving riding safety.

[0015] 3. The battery is mounted on the support plate and located directly behind the heat sink. This mounting position makes it easier to install and remove the battery, and facilitates future maintenance and replacement. At the same time, the connection structure design between the components also provides convenience for the maintenance of other components. Attached Figure Description

Detailed Implementation

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this utility model provides an electric off-road motorcycle frame, including a bracket 1, a seat 2, handlebars 3, a front suspension 4, a front wheel 5, a rear swingarm 6, a rear suspension 7, and a rear wheel 8. The seat 2 is mounted on top of the bracket 1, the handlebars 3 are mounted at the front end of the bracket 1, and the front suspension 4 is mounted below the handlebars 3. The front suspension 4 effectively buffers the bumps and impacts encountered by the front wheel 5 during driving. The front wheel 5 is mounted between the front suspensions 4, the rear swingarm 6 is mounted at the rear end of the bracket 1, the rear suspension 7 is mounted above the rear swingarm 6, and the rear wheel 8 is mounted between the right sides of the rear swingarm 6. The rear suspension 7 cooperates with the rear swingarm 6 to improve the vehicle's driving stability under complex road conditions.

[0026] like Figure 2 , 3 As shown in Figures 4, 5, and 6, the bracket 1 includes a head tube 11, side plates 12, a fixing plate 13, a connecting plate 14, and a main beam plate 15. The handle 3 is equipped with a head tube 11. Two symmetrical side plates 12 are fixedly installed on the sides of the head tube 11, and the side plates 12 provide support for the entire frame. The rear end of the side plates 12 is fixedly installed with a fixing plate 13 to enhance the structural strength of the rear end of the side plates 12 and facilitate the fixing of the side plates 12. One end of the connecting plate 14 is installed on the head tube 11 at the lower end of the two side plates 12, and the other end of the connecting plate 14 is equipped with a main beam plate 15. The cross-sectional shape of the main beam plate 15 is U-shaped. A radiator 151 is fixedly installed inside the main beam plate 15. A heat dissipation hole 152 is opened on the main beam plate 15 at the lower end of the radiator 151. The heat dissipation hole 152 is elongated.

[0027] The elongated heat dissipation vents 152 can quickly dissipate heat from the motor, preventing heat buildup inside the bracket 1. This structure effectively solves the problems of insufficient heat dissipation in traditional electric off-road motorcycle brackets 1, which lead to motor performance degradation and shortened battery life, ensuring that core components can still operate stably under high-load conditions during off-road driving.

[0028] like Figure 3 , 5 As shown in Figure 6, an electric plate 16 is installed at the lower end of the main beam plate 15. The cross-sectional shape of the electric plate 16 is V-shaped, and the angle of the V-shaped electric plate 16 is set to an obtuse angle. The obtuse angle V-shaped design can optimize the stress structure of the electric plate 16 and improve the support stability. An electric motor is fixedly installed on the electric plate 16, and both sides of the electric plate 16 are fixed on the side plate 12, which further enhances the connection between the electric plate 16 and the bracket 1.

[0029] like Figure 3 , 4 As shown in Figures 5 and 6, a support plate 17 is installed at the unclosed end of the U-shaped main beam plate 15. The cross-sectional shape of the support plate 17 is L-shaped. The long side of the support plate 17 is located on the main beam plate 15, and the two sides of the short side of the support plate 17 are located between the two side plates 12. The L-shaped structure can provide support for both the main beam plate 15 and the side plates 12 at the same time, thereby improving the overall structural stability of the bracket 1.

[0030] like Figure 2 , 3 As shown in Figures 5 and 6, a limiting plate 18 is installed on the short side of the support plate 17, and the limiting plate 18 is located between the two side plates 12. At the same time, a fixing plate 13 is installed on the upper end of the limiting plate 18. A hinge block 181 for fixing the rear suspension 7 is fixedly installed on the right side of the fixing plate 13. The hinge block 181 provides a stable installation position for the rear suspension 7, ensuring precise cooperation between the rear suspension 7 and the rear rocker arm 6. It can effectively buffer the impact during off-road bumps, improve the vehicle's driving stability, and avoid the handling risk caused by the loose installation of the rear suspension 7.

[0031] like Figure 1 , 5 As shown in Figure 6, the battery 19 is installed on the support plate 17. The battery 19 is placed directly on the support plate 17 without a complicated obstruction structure. When replacing or repairing the battery 19, it can be removed by simply disassembling the fixing parts without disassembling other core structures of the bracket 1. Furthermore, the battery 19 on the support plate 17 is located directly behind the heat sink 151. The heat sink 151 can simultaneously dissipate heat from the battery 19, preventing the battery 19 from having its performance and lifespan affected by high temperatures. At the same time, this installation position facilitates the installation and removal of the battery 19, making it convenient for future maintenance and replacement.

[0032] The above description is merely illustrative of this disclosure, and modifications may be made to the present invention in light of the above detailed description. The terminology used in the appended claims should not be construed as limiting the present invention to the specific embodiments disclosed in the specification. Rather, the scope of the present invention will be fully defined by the appended claims, which will be interpreted according to established principles of claim interpretation.
