[0020] In order to clearly illustrate the technical solutions of the embodiments of the present invention or the prior art, the following briefly introduces the drawings required for the description of the embodiments or the prior art. Obviously, the content described below is only one embodiment of the present invention. For those of ordinary skill in the art, all other embodiments obtained without creative efforts belong to the protection scope of the present invention.

[0021] Such asFigure 1 As shown in the figure, an all-terrain vehicle 100 includes a frame 11, a power assembly 12, a running assembly 13, and a body cover 14. The power assembly 12 is basically located on the frame 11 and supported by the frame 11. The running assembly 13 is basically located below the frame 11 and rotatably connected to the frame 11. The running assembly 13 further includes a front wheel 131 and a rear wheel 132 arranged behind the front wheel 131. At least one of the front wheel 131 or the rear wheel 132 is connected to the power assembly 12 and driven by the power assembly 12. The body cover 14 is at least partially located on the frame 11 and fixedly connected to the frame 11. The body cover 14 is used to cover the important components of the all-terrain vehicle 100 and protect the all-terrain vehicle 100. For the convenience of description, the following is also defined as Figure 1 As shown in the figure, the six directions of front, rear, left, right, up, and down are defined as the front, rear, left, right, up, and down directions of the all-terrain vehicle 100.

[0022] As Figures 2 to 4 As shown in the figure, a horizontal plane S1 perpendicular to the length direction of the all-terrain vehicle 100 is defined, and at least one point at the lowest end of the front wheel 131 and the rear wheel 132 is located on the horizontal plane S1. The frame 11 includes a bottom bracket 111 at the bottom end of the all-terrain vehicle 100 and a mounting bracket 112 above the bottom bracket 111. Both the bottom bracket 111 and the mounting bracket 112 are arranged along the extension direction of the horizontal plane S1. The bottom bracket 111 is used to form the foundation of the all-terrain vehicle 100, which is used to carry various components of the all-terrain vehicle 100 and the driver and passengers. The mounting bracket 112 is located above the bottom bracket 111 and cooperates with the bottom bracket 111 to form a three-dimensional accommodation space for installing or accommodating various components of the all-terrain vehicle 100 and the driver and passengers. The frame 11 further includes a support bracket 113 between the bottom bracket 111 and the mounting bracket 112. The support bracket 113 basically extends along the height direction of the all-terrain vehicle 100. One end of the support bracket 113 is connected to the mounting bracket 112, and the other end of the support bracket 113 is connected to the bottom bracket 111.

[0023] At least part of the body cover 14 surrounds and forms a cockpit S1 for accommodating the driver and passengers. It can be understood that the all-terrain vehicle 100 further includes a seat assembly 15. At least part of the seat assembly 15 is inside the cockpit S1. The seat assembly 15 is supported by the frame 11 and used for the driver and passengers to sit on.

[0024] It can be understood that at least part of the frame 11 and at least part of the body cover 14 jointly form the complete structure of the cockpit S1. Among them, at least part of the frame 11 forms the basic structure of the cockpit S1, and at least part of the body cover 14 cooperates with at least part of the frame 11 to make the cockpit S1 form a basically independent or enclosed space.

[0025] Specifically, the cockpit S1 is composed of at least part of the support bracket 113, at least part of the mounting bracket 112, and at least part of the bottom bracket 111. As an alternative implementation, the support brackets 113 located on the left and right sides of the cockpit S1 are defined as the first support brackets 1131, and the support brackets 113 located on the front side of the cockpit S1 are defined as the second support brackets 1132.

[0026] As Figure 3 shown, specifically, the body covering 14 includes a bottom plate 141, a front baffle 142, and a rear baffle 143. The bottom plate 141 is basically located at the bottom of the cockpit S1, the front baffle 142 is basically located at the front of the cockpit S1, and the rear baffle 143 is located at the rear of the cockpit S1. Further, the body covering 14 also includes side baffles 144 located on both sides of the cockpit S1 along the width direction of the all-terrain vehicle 100 and doors 145 that cooperate with the side baffles 144. Thus far, the components of the bottom plate 141, the front baffle 142, the rear baffle 143, the side baffles 144, and the doors 145 constitute a substantially independent cockpit S1. It can be understood that at least part of the front wheel 131 is located in front of the front baffle 142, and at least part of the rear wheel 132 is located behind the rear baffle 143.

[0027] The bottom plate 141 is basically located below the bottom bracket 111 and is connected to the bottom bracket 111. The rear back plate 143, the front baffle 142, and the side baffle 144 are respectively connected to the support bracket 113. Specifically, the front baffle 142 is connected to the first support bracket 1131 and the second support bracket 1132. The front baffle 142 is recessed inward between the first support bracket 1131 and the second support bracket 1132 to form a wheel compartment S2 for accommodating the front wheels 131. The front end of the side baffle 144 is also connected to the second support bracket 1132, and the wheel compartment S2 is at least partially located inside the side baffle 144. It can be understood that the front wheels 131 include a left front wheel 1311 and a right front wheel 1312. Correspondingly, there are two wheel compartments S2, and the two wheel compartments S2 are distributed along the width direction of the all-terrain vehicle 100. The left front wheel 1311 and the right front wheel 1312 are respectively located in the two wheel compartments S2 distributed along the width direction. As an alternative implementation, the material of the bottom plate 141 is plastic. Specifically, the material of the bottom plate 141 is high-density polyethylene (HDPE). This material has good wear resistance, strong chemical stability, and good corrosion resistance, and can provide high-strength support for the cockpit S1. In addition, the bottom plate 141 and the bottom bracket 111 are detachably connected by bolts. Also, the material of the front baffle 142 is also plastic. Further, the front baffle 142 can use polypropylene (PP). This material has excellent heat resistance, electrical insulation, and high-strength mechanical properties. It can be understood that the instrument panel and a large number of electronic components of the all-terrain vehicle 100 are arranged on and connected to the front baffle 142. The good chemical properties of polypropylene can effectively isolate the harm caused by the leakage of electronic components to the cockpit S1. And when the cockpit S1 is a fully enclosed cockpit S1, it can effectively keep the cockpit S1 warm or cold. And the selection of the above materials can effectively achieve the lightweight of the all-terrain vehicle 100. Regardless of the materials used for the front baffle 142 and the bottom plate 141, in order to effectively protect the cockpit S1 by the front baffle 142 and the bottom plate 141, the yield strength of the front baffle 142 is greater than or equal to 27 MPa.

[0028] This application also includes a suspension assembly 16 (see Figure 1 ), and the front wheels 131 are connected to the vehicle frame 11 through the suspension assembly 16, that is, at least part of the suspension assembly 16 is also located inside the wheel compartment S2. As shown in Figure 4As shown, a first transverse plane P2 is defined as an imaginary plane perpendicular to the length direction of the all-terrain vehicle 100 and passing through at least one point at the rearmost end of the front fender 142. The area located in front of the first transverse plane P2 is defined as the observation area. Understandably, when observing the all-terrain vehicle 100 within the observation area, at least part of the wheelhouse S2 can be observed. Understandably, this means that during the driving process of the all-terrain vehicle 100, sharp obstacles within the observation area of the all-terrain vehicle 100 may pass through the suspension assembly 16 or the front wheel 131 and directly stab towards the wheelhouse S2, resulting in damage to the wheelhouse S2 or even penetrating the wheelhouse S2 and causing injury to the driver and passengers.

[0029] As Figure 3 can be seen, the all-terrain vehicle 100 further includes a heat dissipation assembly 17 and a transmission assembly (not shown in the figure). The heat dissipation assembly 17 and the transmission assembly are located in front of the front fender 142. Further, when observing along the length direction of the all-terrain vehicle 100, the heat dissipation assembly 17 and the transmission assembly located in front of the front fender 142 are basically located between the wheelhouses S2. Moreover, the body covering 14 further includes a front cover plate 147, which is located in front of the front fender 142 and is used to cover the transmission assembly and the heat dissipation assembly 17 located in front of the front fender 142. Understandably, the heat dissipation assembly 17, the transmission assembly, and the front cover plate 147 can form an effective block and protection for the front fender 142 between the wheelhouses S2 distributed along the width direction, while the wheelhouses S2 on both sides of the above area are in an area vulnerable to impact.

[0030] As Figure 3As shown, when observing along the length direction of the all-terrain vehicle 100, the curved surface of the front fender 142 that is recessed inward to form the wheelhouse S2 area is defined as the first impact-resistant surface P3. In other words, the curved surface of the front fender 142 located between the first support bracket 1131 and the second support bracket 1132 is defined as the first impact-resistant surface P3. It can be understood that although the front wheel 131 is in front of the first impact-resistant surface P3, there is still a relatively large space between the front wheel 131 and the front fender 142. Due to the uncontrolled angle of the puncture object, the first impact-resistant surface P3 is basically in a relatively weak state. Based on this, the body covering 14 further includes a reinforcing plate 148. The reinforcing plate 148 is used to provide enhanced protection to the bottom plate 141 or the front fender 142, facilitating enhanced protection of the cockpit S1. Specifically, the reinforcing plate 148 includes a first reinforcing plate 1481 for enhancing the impact resistance of the front fender 142. The contour of the first reinforcing plate 1481 is basically the same as that of the first impact-resistant surface P3, for better fitting with the first impact-resistant surface P3 while not obstructing the accommodation space of the wheelhouse S2. It can be understood that since the wheelhouse S2 includes two wheelhouses S2 distributed along the width direction of the all-terrain vehicle 100, the first reinforcing plate 1481 is also provided in two, respectively for enhancing the two first impact-resistant surfaces P3 distributed along the width direction of the all-terrain vehicle 100.

[0031] Specifically, the first reinforcing plate 1481 and the first impact-resistant surface P3 are fixedly connected through a connecting member, such as being fixed with screws or rivets. The material of the first reinforcing plate 1481 can be set as metal to facilitate strong protection of the first impact-resistant surface P3. For example, the first reinforcing plate 1481 can be aluminum, stainless steel, or other composite materials. As another alternative implementation, for the aesthetics of the all-terrain vehicle 100, the first reinforcing plate 1481 can be plastic, and the first reinforcing plate 1481 is fixed to the first impact-resistant surface P3 by gluing. This material selection and fixing method can not only make the cockpit S1 more aesthetically pleasing when observed from the outside but also achieve an increase in the strength of the first impact-resistant surface P3. As an alternative, the thickness of the first reinforcing plate 1481 should be less than or equal to the thickness of the front fender 142. This method can effectively improve the puncture resistance of the wheelhouse S2 while minimizing the change to the appearance parts of the all-terrain vehicle 100 as much as possible.

[0032] Such as Figure 4As shown, the extension plane of the bottom plate 141 is defined as the bottom plane P4, and the angle between the bottom plane P4 and the horizontal plane S1 is -7.2° to 8.2°. It can be seen that in some specific embodiments or some working conditions, along the front direction of the all-terrain vehicle 100 to the rear of the all-terrain vehicle 100, the projection area of ​​the bottom plate 141 on the first transverse plane P2 is greater than 0. As mentioned above, in this application, the material of the bottom plate 141 is a plastic. It can be seen that during the movement of the all-terrain vehicle 100, the bottom plate 141 is also at risk of being pierced by a piercing object located in front and at the bottom. Based on this, the reinforcing plate 148 also includes a second reinforcing plate 1482 located below the bottom plate 141, and the second reinforcing plate 1482 is connected to the bottom plate 141 to strengthen the rigidity and strength of the bottom plate 141. As an optional implementation, the area of ​​the second reinforcing plate 1482 is substantially consistent with the area of ​​the bottom plate 141 , and the shape of the second reinforcing plate 1482 is substantially consistent with the shape of the second reinforcing plate 1482 , so as to facilitate better fit between the first reinforcing plate 1481 and the second reinforcing plate 1482 , and effectively realize the reinforcement of the rigidity of the bottom plate 141 .

[0033] As another possible implementation, Figure 4 As shown, an imaginary plane perpendicular to the length direction of the all-terrain vehicle 100 and passing through the indexing point (SIP) of the seat assembly 15 is defined as the second transverse plane P5, and the bottom of the bottom plate 141, that is, the side facing the horizontal plane S1 and the surface located in front of the second transverse plane P5 is defined as the second impact-resistant surface P6. The area of ​​the second reinforcing plate 1482 is set to be substantially consistent with the second impact-resistant surface P6, and the contour of the second reinforcing plate 1482 is also substantially consistent with the contour of the second impact-resistant surface P6, so as to better fit the second reinforcing plate 1482.

[0034] As an optional embodiment, the body cover 14 also includes an interior panel 149, which is located above the bottom bracket 111 and connected to the bottom bracket 111. Specifically, the interior panel 149 is located between the seat assembly 15 and the front baffle 142, and is used for the driver and passengers to place their feet and belongings, making the space in the cabin S1 more comfortable and beautiful. The interior panel 149 can be set to metal or other strong materials that can meet the strength required by the aforementioned reinforcement plate 148, and the strength of the second impact-resistant surface P6 of the all-terrain vehicle 100 can be strengthened by the interior panel 149. Furthermore, the bottom of the seat assembly 15 can also be set to a metal part and a reinforcement part with higher strength, so that the safety performance of the cockpit of the all-terrain vehicle 100 can be strengthened by the seat and the interior panel 149.

[0035] Optionally, the second reinforcement plate 1482 can also be fixedly connected to the bottom bracket 111, that is, the second reinforcement plate 1482 is detachably connected to the vehicle frame 11 directly by penetrating the bottom plate 141. This setting method can not only avoid the connection failure between the bottom plate 141 and the reinforcement plate 148, but also further strengthen the connection between the bottom plate 141 and the bottom of the vehicle frame 11. The second reinforcement plate 1482 can be made of metal material or non-metal material. As mentioned above, the first reinforcement plate 1481 is made of plastic. In this application, the material of the second reinforcement plate 1482 is basically the same as that of the first reinforcement plate 1481. Optionally, the first reinforcement plate 1481 and the second reinforcement plate 1482 are made of nylon (PA, Polyamide), and the thickness of the second reinforcement plate 1482 is less than or equal to the thickness of the bottom plate 141.

[0036] In other embodiments, the second reinforcement plate 1482 can also be made of metal material. Further, the material of the second reinforcement plate 1482 can be basically the same as that of the bottom plate 141. When the material of the second reinforcement plate 1482 is basically the same as that of the bottom plate 141. As an alternative embodiment, the second reinforcement plate 1482 and the bottom plate 141 can be integrally formed. In order to effectively achieve the lightweight and cost control of the original body covering 141 of the all-terrain vehicle 100, the strength of the first impact-resistant surface P3 and the second impact-resistant surface P6 is mainly borne by the reinforcement plate 148. To effectively achieve the above object, the yield strength ratio between the reinforcement plate 148 and the body covering 141 connected thereto is between 2 and 7. Specifically, that is, the yield strength ratio between the first reinforcement plate 1481 and the front baffle 142 is between 2 and 7, and the yield strength ratio between the second reinforcement plate 1482 and the bottom plate 141 is between 2 and 7.

[0037] Optionally, the first reinforcement plate 1481 and the second reinforcement plate 1482 can be separately arranged, especially when the materials between the first reinforcement plate 1481 and the second reinforcement plate 1482 are different, that is, the first reinforcement plate 1481 and the second reinforcement plate 1482 are in a separated state, and they are respectively connected to the first impact-resistant surface P3 and the second impact-resistant surface P6. Further, the two first reinforcement plates 1481 are also independent of each other and in a separated state. This setting method can make the installation of the reinforcement plate 148 more flexible, and can adapt to the manufacturing error of the all-terrain vehicle 100, and can better cover the impact weak surface of the all-terrain vehicle 100.

[0038] Optionally, the first reinforcing plate 1481 and the second reinforcing plate 1482 can also be integrally formed or fixedly connected. That is, the first reinforcing plate 1481 is located in front of the second reinforcing plate 1482, and the integral formation or fixed connection between the first reinforcing plate 1481 and the second reinforcing plate 1482. Further, the relative layout between the first reinforcing plate 1481 and the second reinforcing plate 1482 is basically the same as the layout between the bottom plate 141 and the front baffle 142. This setting method makes the installation between the first reinforcing plate 1481 and the second reinforcing plate 1482 more convenient, that is, by positioning one of the reinforcing plates 148, the other reinforcing plate 148 can be quickly positioned.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by using equivalent replacements or equivalent transformations fall within the protection scope of the present invention.
