Description

Technical Field

[0001] This invention belongs to the field of vehicle parts technology, and in particular relates to a front and rear buffer structure for ATVs and its usage method. Background Technology

[0002] ATVs are light motor vehicles designed specifically for off-road driving. They typically have wide tires, high ground clearance, and powerful power systems to travel on various complex terrains, including but not limited to beaches, mud, grasslands, mountains, deserts, and snow. A buffer structure is an important component of an ATV. For example, patent application number CN201921638174.5 discloses a ATV frame buffer device, which includes a frame and a buffer mechanism. The frame includes two main beams, a crossbeam, and a mounting plate. The two main beams are welded together by the crossbeam. A connecting plate is welded to the end of each main beam. The mounting plate is bolted to the connecting plate. The buffer mechanism is fixed to the front side wall of the mounting plate and includes a crash plate, two support rods, a buffer element, a second spring, and a positioning rod.

[0003] While the existing ATV cushioning structure can buffer the impact of a collision, the enormous elastic force generated by the spring during the release of the impact can easily cause secondary injuries to the vehicle and the user. It can also make the ATV uncontrollable after a collision, reducing the safety of ATV use. The traditional frame-type cushioning structure is not energy-absorbing enough and cannot effectively protect against collision impacts. Therefore, it is necessary to make improvements. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a front and rear buffer structure for beach buggies and its usage method, thereby effectively improving the safety of beach buggy use.

[0005] In view of this, the present invention provides a front and rear buffer structure for a beach buggy, comprising:

[0006] The main beam has a front end with a collision protection beam, and the main beam extends along the front-rear direction of the ATV and is located inside the ATV wheels.

[0007] Also includes:

[0008] The upper anti-collision frame includes a first frame and a second frame extending in the front-rear direction of the ATV. The first frame is located above the wheels of the ATV, and the second frame is located in front of the wheels of the ATV.

[0009] A connecting arm, which is used to connect the front end of the main beam to the second frame and is located on the front side of the ATV wheel;

[0010] An energy-absorbing box is disposed at the front end of the main beam and connected to the anti-collision crossbeam;

[0011] The connecting arm is plate-shaped, and one side surface of the connecting arm is corrugated by a number of grooves evenly spaced along the vertical direction.

[0012] In this technical solution, the upper anti-collision frame and the main beam are connected by a connecting arm. The corrugated surface of the connecting arm can effectively enhance the front corner structural strength between the upper anti-collision frame and the main beam. In a frontal collision of the ATV, it can more efficiently transfer and disperse collision energy, thereby improving the collision buffering effect of the ATV. At the same time, through the combined action of the upper anti-collision frame, energy absorption box and main beam, the buffering effect of the ATV against collision impact is further guaranteed, improving the safety of ATV use.

[0013] Furthermore, the above technical solution also includes:

[0014] The first protective part is located inside the main beam and is fixedly connected to the main beam. The first protective part can deflect the splash path of the splash generated during the collision and prevent the splash from breaking through to the middle of the ATV.

[0015] Furthermore, the above technical solution also includes:

[0016] The second protective part is located inside the main beam and is fixedly connected to the main beam. The second protective part is in the shape of a parallelogram frame. The second protective part can absorb the collision energy by crushing itself when a collision occurs.

[0017] In the above technical solution, the first protective part further includes:

[0018] The mounting frame is fixedly installed on the inner side of the main beam, and several protective plates are installed on the mounting frame. The protective plates are evenly spaced along the front and rear direction of the ATV.

[0019] The front and rear of the protective plate are distributed in the front and rear directions corresponding to the ATV, and the protective plate has an angle of 45° to 75° with the horizontal plane.

[0020] In the above technical solution, the protective plate further includes:

[0021] An alloy sheet layer, wherein the thickness of the alloy sheet layer is less than two millimeters;

[0022] A rubber sheet layer, the rubber sheet layer being located on the back side of the alloy sheet layer;

[0023] A carbon fiber sheet layer, which is located on the back side of a rubber sheet layer;

[0024] The alloy sheet layer, rubber sheet layer, and carbon fiber sheet layer are bonded to each other with an adhesive.

[0025] In the above technical solution, the second protective part further includes:

[0026] The first group of parallel segments consists of two parallel first poles, which are spaced apart along the front-to-back direction of the ATV.

[0027] The second group of parallel segments consists of two parallel second rods, with the two second rods spaced apart along the left and right directions of the ATV.

[0028] The two ends of the second pole are respectively connected to the same end of the two first poles. The length direction of the first pole is parallel to the left and right direction of the ATV. The first pole located on the front side of the two first poles is connected to the main beam through a connecting column.

[0029] In the above technical solution, the energy-absorbing box further includes:

[0030] A box body having a plurality of crushing grooves that extend along the length of the box body and penetrate the box body;

[0031] The crushing grooves have different shapes and are evenly distributed in the box. The crushing grooves are separated from each other by the groove walls formed by the box.

[0032] Furthermore, the above technical solution also includes:

[0033] Accessories, which are mounted on the connecting arm;

[0034] The accessory may be a circulation pump for beach buggies, and the circulation pump may be arranged in at least one slot of the connecting arm.

[0035] Furthermore, in the above technical solution, the present invention also discloses a method of using the aforementioned front and rear buffer structure of the beach buggy, comprising the following steps:

[0036] S1 is a single-collision buffer. When the ATV collides, the anti-collision beam moves towards the main beam and deforms under the influence of the impact force. The energy absorption box and the anti-collision beam work together to absorb the energy generated by the collision through crushing.

[0037] S2 secondary collision buffer: After the collision impact is transmitted to the main beam, the second protective part, which is in the shape of a parallelogram frame, undergoes crushing deformation under the influence of the collision impact force to absorb the energy generated by the collision. At the same time, the upper anti-collision frame receives the collision energy and disperses it under the action of the connecting arm.

[0038] S3 splash protection: When a collision occurs, the splashes generated by the collision move at high speed towards the main beam under the influence of inertia and impact force. When the splashes come into contact with the first protective part, the first protective part deflects the movement path of the splashes and prevents the splashes from moving directly towards the center of the ATV.

[0039] In this technical solution, when a beach buggy collides, the front and rear buffer structures of the beach buggy can effectively buffer the collision multiple times in a short period of time, thereby effectively preventing users from being injured due to the collision and improving the safety of using the beach buggy.

[0040] The beneficial effects of this invention are:

[0041] 1. The connecting arm design improves the efficiency of energy transfer and dispersion in the event of a collision. Meanwhile, the upper anti-collision frame, main beam, and energy-absorbing box work together to enhance the collision buffering effect of the ATV, thereby improving the safety of the ATV.

[0042] 2. The first protective section effectively protects against splashes generated during collisions, further improving the safety of using the ATV;

[0043] 3. The addition of a second protective section can further enhance the crushing and energy absorption effect of the buffer structure, thereby improving the safety of ATV use. Attached Figure Description

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0056] Example 1:

[0057] This application provides a front and rear buffer structure for an ATV, including: a main beam 1, with an anti-collision crossbeam 2 at the front end of the main beam 1, the main beam 1 extending along the front and rear direction of the ATV and located inside the ATV wheel.

[0058] It also includes: an upper anti-collision frame 3, which includes a first frame 30 and a second frame 31 extending in the front-rear direction of the ATV. The first frame 30 is located above the ATV wheel, and the second frame 31 is located in front of the ATV wheel; a connecting arm 4, which is used to connect the front end of the main beam 1 to the second frame 31 and is located in front of the ATV wheel; and an energy-absorbing box 5, which is located at the front end of the main beam 1 and connected to the anti-collision crossbeam 2.

[0059] The connecting arm 4 is plate-shaped, and one side surface of the connecting arm 4 is corrugated by a number of grooves 40 evenly spaced along the vertical direction.

[0060] Furthermore, the main body of the beach buggy is a conventional beach buggy capable of traversing various terrains, consisting of a body and multiple wheels. The upper bumper 3 is made of slender components with a predetermined cross-sectional shape, such as square tubular components or channel components. A plate is provided between the upper bumper 3 and the main beam 1 to define the wheel wells that accommodate the beach buggy wheels and their suspension. The connecting arm 4 is constructed from a single plate, preferably made of metal, and the longitudinal direction of the groove 40 on the connecting arm 4 extends along the left-right direction of the beach buggy.

[0061] It also includes: accessory 8, which is mounted on connecting arm 4;

[0062] Among them, accessory 8 can be a circulation pump for beach buggies, and the circulation pump can be arranged in at least one slot 40 of the connecting arm 4.

[0063] In this technical solution, the upper anti-collision frame 3 and the main beam 1 are connected by 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 more efficiently transfer and disperse collision energy in a frontal collision of the ATV, thereby improving the collision buffering effect of the ATV. At the same time, through the joint action of the upper anti-collision frame 3, the energy absorption box 5 and the main beam 1, the buffering effect of the ATV against collision impact is further guaranteed, improving the safety of the ATV. In addition, the setting of the groove 40 on the connecting arm 4 can also improve the space utilization efficiency. The accessories 8 of the ATV, such as the circulation pump, can be embedded in the groove 40 of the connecting arm 4, avoiding space waste.

[0064] Example 2:

[0065] This embodiment provides a front and rear buffer structure for a beach buggy. In addition to the technical solutions of the above embodiments, it also has the following technical features, including: a first protective part 6, which is disposed on the inner side of the main beam 1 and fixedly connected to the main beam 1. The first protective part 6 can deflect the splash path of the splashing material generated during the collision and prevent the splashing material from breaking through to the middle of the beach buggy.

[0066] The first protective part 6 also includes: a mounting frame 60, which is fixedly installed on the inner side of the main beam 1. The mounting frame 60 is provided with a number of protective plates 61, which are evenly spaced along the front and rear direction of the beach vehicle.

[0067] The front and rear of the protective plate 61 are distributed in the front and rear directions corresponding to the ATV, and the protective plate 61 has an angle of 45° to 75° with the horizontal plane.

[0068] The protective plate 61 also includes: an alloy sheet layer 610, the thickness of which is less than two millimeters; a rubber sheet layer 611, which is located on the back of the alloy sheet layer 610; and a carbon fiber sheet layer 612, which is located on the back of the rubber sheet layer 611.

[0069] In this process, the alloy sheet layer 610, the rubber sheet layer 611, and the carbon fiber sheet layer 612 are bonded together by an adhesive 613.

[0070] In this embodiment, when a collision occurs, the splashes generated by the collision move at high speed towards the main beam 1 under the influence of inertia and impact force. When the splashes come into contact with the first protective part 6, the protective plate 61 located at the foremost side collides with the splashes first. Since the protective plate 61 has an angle with the horizontal plane, the splashes can be effectively deflected when they collide with the protective plate 61, causing the movement path of the splashes to be deflected towards the ground. At the same time, the arrangement of several protective plates 61 can prevent some of the splashes from penetrating the protective plates 61 and continuing to move towards the center of the ATV. Furthermore, the inclined design of several protective plates 61 allows the splashes to be protected by the action of the next protective plate 61 after penetrating one protective plate 61. The projectile continues to be deflected, ensuring that it does not move to the center of the ATV. At the same time, the multi-layered design of the protective plate 61 reduces its weight while maintaining its impact resistance. The alloy sheet layer 610, rubber sheet layer 611, and carbon fiber sheet layer 612 are bonded together by adhesive 613. When the projectile impacts the protective plate 61, for example, after penetrating the alloy sheet layer 610, it collides with the rubber sheet layer 611. At this time, the adhesive 613 will delaminate under the impact. The pulling of the adhesive 613 can further weaken the impact force of the projectile, thereby reducing the occurrence of the projectile penetrating the protective plate 61.

[0071] Example 3:

[0072] This embodiment provides a front and rear buffer structure for an ATV. In addition to the technical solutions of the above embodiments, it also has the following technical features, including: a second protective part 7, which is disposed inside the main beam 1 and fixedly connected to the main beam 1. The second protective part 7 is in the shape of a parallelogram frame and can absorb collision energy through its own crushing destruction during a collision. The second protective part 7 also includes: a first set of parallel sections, which consists of two mutually parallel first rods 70 spaced apart along the front-rear direction of the ATV; and a second set of parallel sections, which consists of two mutually parallel second rods 71 ​​spaced apart along the left-right direction of the ATV.

[0073] The two ends of the second rod 71 are connected to the same end of the two first rods 70 respectively. The length direction of the first rod 70 is parallel to the left and right direction of the beach buggy. The first rod 70 located on the front side of the two first rods 70 is connected to the main beam 1 through the connecting column 72.

[0074] In this embodiment, by setting the second protective part 7, and because the second protective part 7 is composed of a first set of parallel segments and a second set of parallel segments forming a parallelogram frame, the second protective part 7 can more easily generate crushing and shrinking deformation when subjected to collision impact, thereby quickly absorbing collision energy, effectively improving the collision buffering performance of the ATV, and thus improving the safety of using the ATV.

[0075] Example 4:

[0076] This embodiment provides a front and rear buffer structure for a beach buggy. In addition to the technical solutions of the above embodiments, it also has the following technical features: the energy-absorbing box 5 further includes a box body 50, which has a plurality of crushing grooves 51. The crushing grooves 51 extend along the length of the box body 50 and penetrate through the box body 50.

[0077] Among them, several crushing grooves 51 have different shapes and are evenly distributed in the box body 50. The crushing grooves 51 are separated from each other by the groove 40 wall formed by the box body 50.

[0078] In this embodiment, by providing several crushing grooves 51 in the energy-absorbing box 5, the crushing energy absorption effect of the energy-absorbing box 5 can be effectively increased, thereby improving the buffering effect of the ATV and reducing the impact of collisions on the ATV and the user.

[0079] Example 4:

[0080] This embodiment provides a method for using the front and rear buffer structure of a beach buggy. In addition to the technical solution of the above embodiment, it also has the following technical features, including the following steps:

[0081] S1 is a primary collision buffer. When the ATV collides, the anti-collision beam 2 moves towards the main beam 1 and deforms under the influence of the collision impact force. The energy absorption box 5 works together with the anti-collision beam 2 and absorbs the energy generated by the collision through crushing.

[0082] S2 secondary collision buffer: after the collision impact is transmitted to the main beam 1, the second protective part 7, which is in the shape of a parallelogram frame, undergoes crushing deformation under the influence of the collision impact force to absorb the energy generated by the collision. At the same time, the upper anti-collision frame 3 receives the collision energy and disperses it under the action of the connecting arm 4.

[0083] S3 splash protection: When a collision occurs, the splashes generated by the collision move at high speed towards the main beam 1 under the influence of inertia and impact force. When the splashes come into contact with the first protective part 6, the first protective part 6 deflects the movement path of the splashes and prevents the splashes from moving directly towards the center of the ATV.

[0084] In this embodiment, when a beach buggy collides, the front and rear buffer structures of the beach buggy can effectively buffer the collision multiple times in a short period of time, thereby effectively preventing users from being injured due to the collision and improving the safety of using the beach buggy.

[0085] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
