Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle accessories, and particularly relates to a front and rear buffer structure for an ATV and a usage method thereof. Background Art

[0002] An ATV is a light motor vehicle designed for off-road driving. They usually have wide tires, a high ground clearance, and a powerful power system to travel on various complex terrains, including but not limited to beaches, mud, grasslands, mountains, deserts, and snow. The buffer structure is an important component in an ATV. For example, a frame buffer device for an ATV disclosed in the patent with the application number CN201921638174.5 includes a frame and a buffer mechanism. The frame includes two main beams, a cross beam, and a mounting plate. The two main beams are fixedly welded by the cross beam. A connecting plate is fixedly welded to the end of the main beam. The mounting plate is fixedly installed with the connecting plate by bolts. The buffer mechanism is fixed to the front side wall of the mounting plate. The buffer mechanism includes a collision prevention plate, two support rods, a buffer member, a second spring, and a positioning rod.

[0003] In the process of using this existing ATV buffer structure, although the spring can buffer the collision impact, the huge elastic force generated by the spring due to the strong impact is likely to cause secondary injuries to the vehicle body and the user during the release process. At the same time, it is easy to make the ATV out of control after a collision, reducing the safety of using the ATV. While the traditional frame-type buffer structure has insufficient energy absorption effect and cannot effectively protect against the collision impact. Therefore, it is necessary to make improvements. Summary of the Invention

Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0056] Embodiment 1:

[0057] The embodiment of the present application provides a front and rear buffering structure for an ATV, including: a main beam 1, a front end of the main beam 1 is provided with an anti-collision cross beam 2, and the main beam 1 extends along the front and rear directions of the ATV and is located inside the ATV wheels;

[0059] Wherein, the connecting arm 4 is plate-shaped and one side surface of the connecting arm 4 forms a corrugated surface through a plurality of grooves 40 evenly distributed at intervals in the up-down direction.

[0060] Moreover, the ATV main body is a conventional ATV capable of traveling on various terrains, with a vehicle body and multiple wheels. The upper anti-collision frame 3 is made of an elongated member with a predetermined cross-sectional shape, such as a square tube member or a channel member. A plate is arranged between the upper anti-collision frame 3 and the main beam 1 to define a wheel well for accommodating the wheels of the ATV and its suspension. The connecting arm 4 is composed of a single plate, the connecting arm 4 is preferably made of a metal material, and the length direction of the grooves 40 on the connecting arm 4 extends along the left-right direction of the ATV.

[0061] It further includes: a fitting 8, the fitting 8 is arranged on the connecting arm 4;

[0062] Wherein, the fitting 8 can be a circulation pump for the ATV, and the circulation pump can be arranged in at least one groove 40 of the connecting arm 4.

[0063] In this technical solution, through the arrangement of the connecting arm 4, the upper anti-collision frame 3 is connected with the main beam 1 through the connecting arm 4. The corrugated surface of the connecting arm 4 can effectively enhance the front corner structural strength between the upper anti-collision frame 3 and the main beam 1, and can transfer and disperse the collision energy more efficiently in the frontal collision of the ATV, thereby improving the collision buffer effect of the ATV. At the same time, through the combined action of the upper anti-collision frame 3, the energy-absorbing box 5 and the main beam 1, the buffer effect of the ATV against the collision impact is further ensured, improving the use safety of the ATV. At the same time, the arrangement of the grooves 40 on the connecting arm 4 can also improve the space utilization efficiency. The fitting 8 of the ATV, such as a circulation pump, can be embedded in the grooves 40 of the connecting arm 4 to avoid space waste.

[0064] Embodiment 2:

[0065] This embodiment provides a front-rear buffer structure for an ATV. In addition to including the technical solutions of the above embodiment, it also has the following technical features. It further includes: a first protection part 6, the first protection part 6 is arranged inside the main beam 1 and is fixedly connected with the main beam 1. The first protection part 6 can deflect the flying path of the flying objects generated during the collision and prevent the flying objects from breaking through to the middle part of the ATV.

[0066] The first protection part 6 further includes: a mounting frame 60, which is fixedly arranged inside the main beam 1. A plurality of protection plates 61 are arranged on the mounting frame 60, and the plurality of protection plates 61 are evenly spaced along the front-rear direction of the ATV;

[0067] Among them, the front and rear faces of the protection plate 61 are distributed corresponding to the front-rear direction of the ATV, and there is an angle of 45° to 75° between the protection plate 61 and the horizontal plane.

[0068] The protection plate 61 further includes: an alloy thin plate layer 610, the thickness of the alloy thin plate layer 610 is less than two millimeters; a rubber plate layer 611, the rubber plate layer 611 is located on the back of the alloy thin plate layer 610; a carbon fiber plate layer 612, the carbon fiber plate layer 612 is located on the back of the rubber plate layer 611;

[0069] Among them, the alloy thin plate layer 610, the rubber plate layer 611 and the carbon fiber plate layer 612 are bonded to each other by an adhesive 613.

[0070] In this embodiment, when a collision occurs, the flying objects generated by the collision move at high speed towards the main beam 1 under the influence of inertia and impact force. When the flying objects contact the first protection part 6, the protection plate 61 at the frontmost side first collides with the flying objects. Since there is an angle between the protection plate 61 and the horizontal plane, the flying objects can be effectively deflected in their moving paths when colliding with the protection plate 61, so that the moving paths of the flying objects deflect towards the ground. At the same time, the arrangement of the plurality of protection plates 61 can prevent the phenomenon that some flying objects penetrate through the protection plate 61 and continue to move towards the middle of the ATV. And the inclined design of the plurality of protection plates 61 enables the flying objects to continue to be deflected in their moving paths under the action of the next protection plate 61 after penetrating through one protection plate 61, ensuring that the flying objects do not move to the middle of the ATV. At the same time, the multi-layer setting of the protection plate 61 can ensure the impact resistance of the protection plate 61 while reducing the weight of the protection plate 61. And the alloy thin plate layer 610, the rubber plate layer 611 and the carbon fiber plate layer 612 are bonded to each other by the adhesive 613. When the flying objects impact and collide with the protection plate 61, for example, after the flying objects penetrate through the alloy thin plate layer 610 and collide with the rubber plate layer 611, at this time, the adhesive 613 will experience a degumming phenomenon under the action of the impact. The pulling force of the adhesive 613 can further weaken the impact force of the flying objects, thereby reducing the phenomenon that the flying objects penetrate through the protection plate 61.
