[0001] The utility model relates to the technical field of ATV frames, in particular to an ATV frame with high strength. Background Art

[0002] The design of the ATV frame is crucial to the performance of the all-terrain vehicle. It not only needs to support the key components of the vehicle, such as the engine, seat and suspension system, but also ensure the vehicle's maneuverability and safety. Existing ATV frames are usually composed of front and rear frames, and these two parts usually adopt a fixed integrated structural design, which provides good integrity and stability.

[0003] However, although this one-piece structure has advantages in durability, it also has some limitations. First, it may make the installation and removal of the front frame and the rear frame complicated, which is a challenge for users who need to frequently perform maintenance and replace parts. Second, when the vehicle needs to be cleaned, maintained or parts replaced, the one-piece frame design may limit the user's operating space and convenience.

[0004] Based on this, we propose an ATV frame with high strength to solve the above-mentioned problems. Utility Model Content

[0005] In order to improve the above-mentioned problems, the utility model provides an ATV frame with high strength.

[0006] The utility model provides an ATV frame with high strength, which adopts the following technical scheme: an ATV frame with high strength, wherein the ATV frame and ATV wheels form an ATV body, wherein the ATV wheels are mounted on both sides of the ATV frame, wherein the ATV frame comprises a front frame, wherein one end of the front frame is connected to a rear frame, and a spring shock absorber is further arranged between the front frame and the rear frame;

[0007] The front frame comprises a first support frame body, a front drive bracket is connected to the bottom of one end of the first support frame body, and a pedal bracket is also arranged at one end of the first support frame body away from the front drive bracket.

[0008] As a high-strength ATV frame described in the utility model, a support beam plate is installed on the top of one end of the first support frame, and a diagonal support plate is connected between the first support frame and the footrest bracket.

[0009] As a high-strength ATV frame described in the utility model, the front drive bracket includes a front beam arm plate, a reinforcement block is welded and connected between the front beam arm plate and the first support frame body, and front wheel connectors are respectively provided at both ends of the front beam arm plate.

[0010] As a high-strength ATV frame described in the utility model, the rear frame includes a second support frame body, and the middle of one end of the second support frame body and the first support frame body are respectively equipped with hinge seats for connecting spring shock absorbers.

[0011] As a high-strength ATV frame described in the utility model, the first support frame body and the second support frame body are both formed by welding and splicing chromium-molybdenum alloy steel pipes.

[0012] As a high-strength ATV frame described in the utility model, the second support frame is rotatably connected to the end away from the hinge seat with a transmission shaft, one end of the transmission shaft is provided with a driving wheel disc, and the end of the transmission shaft away from the driving wheel disc is provided with a transmission gear plate, and both ends of the transmission shaft and one end of the front wheel connector are respectively connected to a fixed base for installing the ATV wheel.

[0013] In summary, the present invention has at least one of the following beneficial effects:

[0014] 1. The ATV frame design of this scheme adopts a split structure, which mainly divides the frame into two parts: a front frame and a rear frame. This design significantly improves the convenience of assembly and disassembly, making the maintenance and replacement of the ATV frame easier. By installing a spring shock absorber between the front frame and the rear frame, it not only enhances the connection stability of the two parts, but also effectively reduces the fluctuation and impact during driving, reduces the loose connection caused by ups and downs, and thus improves the connection strength. In addition, the split design also allows designers to design a more flexible and changeable frame structure without sacrificing performance to meet the needs and usage scenarios of different users, thereby enhancing the versatility and personalized customization of the ATV frame.

[0015] 2. The ATV frame designed in this scheme adopts chromium-molybdenum alloy steel tubes as the constituent materials of the first support frame and the second support frame. Due to its alloy composition, especially the addition of chromium and molybdenum, this material exhibits higher strength and hardness than ordinary steel tubes. The welded support frame significantly improves the overall mechanical strength of the ATV frame, enabling it to withstand greater loads and impact forces, helping to extend the service life of the frame and reduce maintenance requirements. At the same time, the lightweight chromium-molybdenum alloy steel tube frame design does not sacrifice the required strength, making the vehicle more flexible while maintaining performance, significantly improving controllability and safety, and reducing the risk of damage under accidents or extreme use conditions.

[0022] The following is combined with Figure 1-4 The utility model is described in further detail.

[0023] See also Figure 1-3 The utility model provides an ATV frame with high strength, wherein the ATV frame 2 and the ATV wheels 3 form an ATV body 1, the ATV wheels 3 are installed on both sides of the ATV frame 2, the ATV frame 2 includes a front frame 4, one end of the front frame 4 is connected to the rear frame 5, a spring shock absorber 6 is also arranged between the front frame 4 and the rear frame 5, the front frame 4 includes a first support frame body 7, the bottom of one end of the first support frame body 7 is connected to the front drive bracket 8, the end of the first support frame body 7 away from the front drive bracket 8 is also provided with a footrest bracket 9, a support beam plate 10 is installed on the top of one end of the first support frame body 7, an oblique support plate 11 is connected between the first support frame body 7 and the footrest bracket 9, and the support beam plate 10 and the oblique support plate 11 installed on the first support frame body 7 are used for supporting and connecting components such as the front of the vehicle and the seat.

[0024] See also Figure 2-4The front drive bracket 8 includes a front beam arm plate 12, and a reinforcement block 13 is welded between the front beam arm plate 12 and the first support frame body 7. Front wheel connectors 14 are also provided at both ends of the front beam arm plate 12. The reinforcement block 13 welded between the front beam arm plate 12 and the first support frame body 7 can increase the welding area between the front drive bracket 8 and the first support frame body 7. At the same time, it can also reduce single-point stress concentration and improve the durability of the ATV frame 2. When the ATV vehicle passes through a rough road or performs complex actions, the reinforcement block 13 helps to absorb and distribute the impact force to avoid direct The rear frame 5 is directly connected to the frame body, and includes a second support frame body 15. A hinge seat 16 for connecting the spring shock absorber 6 is respectively installed in the middle of one end of the second support frame body 15 and the first support frame body 7. The spring shock absorber 6 can be fixedly installed between the first support frame body 7 and the second support frame body 15 by adding the hinge seat 16 in the middle of one end of the second support frame body 15 and the first support frame body 7, so that the spring shock absorber 6 can play a buffering role between the first support frame body 7 and the second support frame body 15, thereby effectively absorbing the impact and vibration from the ground.

[0025] The first support frame 7 and the second support frame 15 are both welded and spliced ​​with chrome-molybdenum alloy steel pipes. The first support frame 7 and the second support frame 15 in this solution are both welded and spliced ​​with chrome-molybdenum alloy steel pipes. The use of the chrome-molybdenum alloy steel pipe provides significant material advantages and structural reinforcement in the design of the ATV frame 2. First of all, due to its alloy composition, especially the addition of chromium and molybdenum, this steel pipe exhibits higher strength and hardness than ordinary steel pipes. The welded support frame significantly improves the overall mechanical strength of the ATV frame 2, enabling it to withstand greater loads and impact forces. In addition, the wear resistance and impact resistance of the chrome-molybdenum alloy steel pipe are crucial for ATV driving in changeable terrains, helping to extend the service life of the frame and reduce maintenance requirements. At the same time, the chrome-molybdenum alloy steel pipe maintains a lighter weight while maintaining high strength, optimizing the weight-to-strength ratio, which is particularly important for all-terrain vehicles because it is directly related to the vehicle's maneuverability and response speed. The lightweight frame design does not sacrifice the required strength, making the vehicle more flexible while maintaining performance.

[0026] See also Figure 4 The end of the second support frame 15 away from the hinge seat 16 is rotatably connected to a transmission shaft 17, one end of the transmission shaft 17 is provided with a driving wheel disc 18, and the end of the transmission shaft 17 away from the driving wheel disc 18 is provided with a transmission sprocket 19. Both ends of the transmission shaft 17 and one end of the front wheel connector 14 are also respectively connected to a fixed base 20 for installing the ATV wheel 3. Through the integrated design of the second support frame 15 and the transmission shaft 17, the driving wheel disc 18, the transmission sprocket 19 and the fixed base 20, an efficient and stable power transmission system is constructed to effectively ensure the power output and transmission efficiency of the vehicle.

[0027] Working principle: The ATV frame 2 designed in this scheme is mainly composed of two parts, a front frame 4 and a rear frame 5. Through this split structural design, the ATV frame 2 is convenient for assembling and disassembling the front frame 4 and the rear frame 5. With the spring shock absorber 6 installed between the front frame 4 and the rear frame 5, the connection stability between the front frame 4 and the rear frame 5 can be improved, and the movement fluctuation generated at the connection between the front frame 4 and the rear frame 5 can be damped, which effectively reduces the loosening of the connection between the front frame 4 and the rear frame 5 caused by the ups and downs of the ATV frame 2 during driving, thereby effectively improving the connection strength between the front frame 4 and the rear frame 5;

[0028] The first support frame 7 and the second support frame 15 in the present solution are both welded and spliced ​​with chrome-molybdenum alloy steel pipes. The use of the chrome-molybdenum alloy steel pipes provides significant material advantages and structural reinforcement in the design of the ATV frame 2. First, due to its alloy composition, especially the addition of chromium and molybdenum, this steel pipe exhibits higher strength and hardness than ordinary steel pipes. The welded support frame significantly improves the overall mechanical strength of the ATV frame 2, enabling it to withstand greater loads and impact forces. In addition, the wear resistance and impact resistance of the chrome-molybdenum alloy steel pipe are crucial for ATV driving in changeable terrains, helping to extend the service life of the frame and reduce maintenance requirements. At the same time, the chrome-molybdenum alloy steel pipe maintains a lighter weight while maintaining high strength, optimizing the weight-to-strength ratio, which is particularly important for all-terrain vehicles because it is directly related to the vehicle's maneuverability and response speed. The lightweight frame design does not sacrifice the required strength, making the vehicle more flexible while maintaining performance.
