Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to an all-terrain vehicle. Background Art

[0002] Currently, in the relevant technology of all-terrain vehicles, the towing ring of an all-terrain vehicle is usually installed on the longitudinal beam of the frame or very close to the longitudinal beam. This is because the longitudinal beam of the frame is relatively strong, which ensures that the structural strength of the towing ring and the frame is sufficient. However, when the all-terrain vehicle is also equipped with a winch, due to the large size of the winch, the winch will occupy the installation space near the longitudinal beam, resulting in the towing ring being unable to be installed on the longitudinal beam or very close to the longitudinal beam. Otherwise, the towing ring will interfere with the winch. Therefore, the towing ring needs to be installed at a certain distance from the longitudinal beam. However, this will result in the towing ring being basically not in the forward extension direction of the longitudinal beam. When the towing ring is subjected to force, it will generate a large torque relative to the longitudinal beam, affecting the connection stability of the towing ring. Therefore, how to improve the connection stability of the towing ring relative to the entire frame is an urgent problem to be solved. Utility Model Content

[0027] See also Figure 1 and Figure 2 An all-terrain vehicle 100 includes a frame 11, a traveling system 12, a power system 13, and a winch device 14. The traveling system 12 is at least partially located below the frame 11. The power system 13 is supported by the frame 11 and is transmission-connected to the traveling system 12. The power system 13 is used to drive the traveling system 12 to travel the all-terrain vehicle 100. The winch device 14 is connected to the front end of the frame 11 and is used to tow or haul the all-terrain vehicle 100.

[0028] Exemplarily, the travel system 12 includes two front travel wheels 121 disposed at the front of the all-terrain vehicle 100 and two rear travel wheels 122 disposed at the rear of the all-terrain vehicle 100. The front travel wheels 121 and the rear travel wheels 122 are respectively rotatably connected to the frame 11.

[0029] For example, Figure 2 and Figure 3 The winch device 14 includes a drum 141, a driver 142, a rope (not shown) and a hook 143. The rope is wound around the drum 141. The hook 143 is connected to the rope and is located at the front end of the frame 11. The driver 142 is used to drive the drum 141 to rotate to wind the rope, so that the rope pulls or drags the all-terrain vehicle 100 for self-rescue or rescue in harsh environments.

[0030] In order to facilitate the description of the technical solutions in this application, this application defines the front, rear, left, right, up and down directions as shown in the figure, wherein the front and rear directions refer to the forward and backward directions of the all-terrain vehicle 100 when traveling, that is, the length direction of the frame 11; the left and right directions refer to the turning directions of the all-terrain vehicle 100 when traveling, that is, the width direction of the frame 11; the up and down directions refer to the height direction of the all-terrain vehicle 100, that is, the height direction of the frame 11.

[0031] In some embodiments, as Figure 3 and Figure 4 As shown, the vehicle frame 11 includes a longitudinal beam 111 and a cross beam 112 connected to the front end of the longitudinal beam 111. The longitudinal beam 111 extends in the front-to-back direction, and the cross beam 112 extends in the left-to-right direction. The winch device 14 is at least partially located below the longitudinal beam 111. The all-terrain vehicle 100 also includes a mounting frame 15 and a towing eye 16. The mounting frame 15 is connected to the cross beam 112. The towing eye 16 is located on the side of the mounting frame 15 facing away from the vehicle frame 11. The towing eye 16 can be used in conjunction with a towing hook to tow or drag the all-terrain vehicle 100, thereby facilitating self-rescue or rescue in adverse environments.

[0032] In some embodiments, as Figure 3 and Figure 4 As shown, the mounting bracket 15 is provided with a slot 17 extending along the width direction of the frame 11. A crossbeam 112 passes through or penetrates the slot 17 and is connected to the slot wall of the slot 17 along the width direction of the frame 11. The cross-section of the crossbeam 112 within the slot 17 is non-circular, which enables the mounting bracket 15 to resist torsion relative to the crossbeam 112 in the width direction of the frame 11. A first weld 18 and a second weld 19 are provided between the mounting bracket and the crossbeam 112. The first weld 18 and the second weld 19 are arranged at intervals along the width direction of the frame 11. This enables the mounting bracket 15 to resist torsion relative to the crossbeam 112 in the height direction of the frame 11. As a result, the towing ring 16 has bidirectional torsion resistance in both the width and height directions of the frame 11, thereby improving the connection stability of the towing ring 16 relative to the entire frame 11.

[0033] In some embodiments, as Figure 4 and Figure 5As shown, the mounting frame 15 includes a first mounting plate body 151, a second mounting plate body 152 and a third mounting plate body 153. The rear plate surface of the first mounting plate body 151 is connected to the front of the cross beam 112, and the front plate surface of the first mounting plate body 151 is connected to the traction ring 16. The second mounting plate body 152 and the third mounting plate body 153 are respectively connected to the two sides of the first mounting plate body 151 along the left and right directions and extend toward the rear of the first mounting plate body 151. The hole groove 17 is formed between the second mounting plate body 152 and the first mounting plate body 151, and / or between the third mounting plate body 153 and the first mounting plate body 151. The first weld 18 is formed between the second mounting plate body 152 and the cross beam 112, and the second weld 19 is formed between the third mounting plate body 153 and the cross beam 112.

[0034] Illustratively, the rear surface of the first mounting plate 151 is connected to the crossbeam 112 by welding, the second mounting plate 152 is connected to the crossbeam 112 by welding a first weld 18, and the third mounting plate 153 is connected to the crossbeam 112 by welding a second weld 19. It is understood that the first mounting plate 151 and the crossbeam 112 may also be connected by bonding, riveting, or screwing.

[0035] In some embodiments, as Figure 5 and Figure 6 As shown, the second mounting plate 152 includes a first plate portion 1521 and a second plate portion 1522. The first plate portion 1521 is located at the bottom of the crossbeam 112 and forms a lower weld 1523 with the crossbeam 112, extending along the length of the vehicle frame 11. The second plate portion 1522 is located on the side of the crossbeam 112 facing away from the first mounting plate 151 and forms an upper weld 1524 with the crossbeam 112, extending along the height of the vehicle frame 11. The upper weld 1524 and the lower weld 1523 together form the first weld 18. A slot 17 is formed between the upper weld 1524, the lower weld 1523, and the first mounting plate 151.

[0036] Illustratively, the cross-sectional outer profile of the cross-beam 112 is rectangular, the upper weld 1524 is substantially parallel to the first mounting plate 151, and the lower weld 1523 is substantially perpendicular to the upper weld 1524, so that the profile of the hole slot 17 is also rectangular, thereby cooperating with the cross-beam 112, thereby enabling the mounting bracket 15 to resist torsion relative to the cross-beam 112 in the width direction of the vehicle frame 11. It is understood that the cross-sectional outer profile of the cross-beam 112 may also be other shapes, such as a triangle. Correspondingly, the upper weld 1524, the lower weld 1523, and the first mounting plate 151 form an angle, so that the profile of the hole slot 17 is also triangular, thereby cooperating with the cross-beam 112, thereby enabling the mounting bracket 15 to resist torsion relative to the cross-beam 112 in the width direction of the vehicle frame 11.

[0037] In some embodiments, as Figure 4and Figure 5 As shown, the first plate portion 1521 and the third mounting plate body 153 are basically symmetrically arranged along a plane in the length direction and the height direction of the frame 11, so that the left and right sides of the mounting frame 15 are at least partially symmetrical, thereby improving the force uniformity of the mounting frame 15 and reducing the risk of stress concentration.

[0038] Exemplarily, the outer contours of the first plate portion 1521 and the third mounting plate body 153 are basically right-angled triangles, and one right-angled side of the first plate portion 1521 and the third mounting plate body 153 are both connected to the first mounting plate body 151, and the hypotenuses of the first plate portion 1521 and the third mounting plate body 153 are arranged toward the rear of the beam 112. Compared with other shapes, the triangular first plate portion 1521 and the third mounting plate body 153 can improve the structural strength and can avoid the winch device 14 through the hypotenuse to reduce the risk of the first plate portion 1521 and the third mounting plate body 153 interfering with the winch device 14.

[0039] In some embodiments, as Figure 4 and Figure 6 As shown, the mounting frame 15 also includes a fourth mounting plate 154, which is connected to the side of the second plate portion 1522 away from the first plate portion 1521 and extends toward the third mounting plate 153 relative to the second mounting plate 152. The fourth mounting plate 154 is located behind the crossbeam 112, and the front side wall of the fourth mounting plate 154 is welded to the crossbeam 112, which can enhance the connection strength between the mounting frame 15 and the crossbeam 112 and improve the connection stability between the mounting frame 15 and the frame 11.

[0040] For example, Figure 2 and Figure 3 As shown, the all-terrain vehicle 100 is further provided with a cover plate 21, which is provided at the front end of the longitudinal beam 111 and covers part of the longitudinal beam 111. The cover plate 21 is used to install other components, wherein the cover plate 21 at least partially covers the upper plate surface of the fourth mounting plate body 154 and is connected to the upper plate surface of the fourth mounting plate body 154. The fourth mounting plate body 154 can play a role in supporting the cover plate 21. At the same time, the fourth mounting plate body 154 can transfer the force of the mounting frame 15 to the longitudinal beam 111 through the cover plate 21, so that the force of the mounting frame 15 can be more efficiently transferred to the longitudinal beam 111, making up for the defect that the mounting frame 15 deviates from the longitudinal beam 111, and improving the force transmission efficiency between the traction ring 16 and the frame 11.

[0041] In some embodiments, as Figure 5As shown, the first mounting plate body 151, the second mounting plate body 152, the third mounting plate body 153 and the fourth mounting plate body 154 are integrally formed to simplify the structure of the mounting frame 15 and improve the production efficiency and assembly efficiency of the mounting frame 15. For example, the first mounting plate body 151, the second mounting plate body 152, the third mounting plate body 153 and the fourth mounting plate body 154 are made of a plate through a sheet metal process, or are integrally formed through a casting process.

[0042] In some embodiments, as Figure 4 and Figure 5 As shown, the third mounting plate 153 extends to the bottom of the cross beam 112 and the longitudinal beam 111. The third mounting plate 153 is at least partially connected to the bottom of the cross beam 112 and at least partially connected to the bottom of the longitudinal beam 111, so that the mounting frame 15 can be directly connected to the longitudinal beam 111 through the third mounting plate 153, so that the force applied to the mounting frame 15 can be more efficiently transmitted to the longitudinal beam 111, thereby improving the force transmission efficiency between the traction ring 16 and the frame 11.

[0043] Exemplarily, the cross-sectional outer contour of the longitudinal beam 111 and the cross beam 112 is rectangular, the third mounting plate 153 is basically perpendicular to the first mounting plate 151 and extends in the front-to-back direction, and the plate thickness wall above the third mounting plate 153 is welded to the bottom surface of the longitudinal beam 111 and the cross beam 112.

[0044] In some embodiments, as Figure 4 and Figure 5 As shown, the third mounting plate 153 is provided with a notch 1531, and the notch 1531 is used to avoid the connection between the crossbeam 112 and the longitudinal beam 111. For example, the front end surface of the longitudinal beam 111 is welded to the crossbeam 112, and there is a welding point between the longitudinal beam 111 and the crossbeam 112. The welding point is likely to bulge relative to the crossbeam 112 and the lower beam surface of the longitudinal beam 111, resulting in the plate thickness wall above the third mounting plate 153 being difficult to fit the lower beam surface of the longitudinal beam 111 and the crossbeam 112, thereby affecting the welding quality. Therefore, the notch 1531 is used to avoid the welding point, so that the plate thickness wall above the third mounting plate 153 can better fit the lower beam surface of the longitudinal beam 111 and the crossbeam 112, so that the third mounting plate 153 can be welded to the longitudinal beam 111 and the crossbeam 112.

[0045] In some embodiments, as Figure 4 and Figure 5As shown, the first mounting plate 151 is provided with a first escape area 1511, which is located near the center of the first mounting plate 151. The crossbeam 112 is provided with a second escape area 1121, which is located opposite the first escape area 1511 along the length of the vehicle frame 11. The first escape area 1511 and the second escape area 1121 are used to avoid tools. For example, during the assembly process, tools can be passed through the first escape area 1511 and the second escape area 1121 to operate on components that are obscured behind the crossbeam 112. For example, a wrench can be inserted into the first escape area 1511 and the second escape area 1121 to tighten a nut behind the crossbeam 112.

[0046] Exemplarily, the first avoidance area 1511 is a through hole, and the second avoidance area 1121 is a through slot. The through hole is connected to the through slot and passes through the mounting frame 15 and the crossbeam 112 on both sides along the length direction of the vehicle frame 11, so that the tool can extend from the front of the first mounting plate 151 to the rear of the crossbeam 112.

[0047] In some embodiments, as Figure 5 As shown, the first mounting plate 151 includes a connected upper plate portion 1512 and a lower plate portion 1513. The upper plate portion 1512 is welded to the crossbeam 112, and the lower plate portion 1513 is located below the crossbeam 112. The second mounting plate 152 and the third mounting plate 153 are respectively connected to opposite sides of the lower plate 1513 along the width direction of the vehicle frame 11. The traction ring 16 is connected to the side of the lower plate 1513 facing away from the crossbeam 112. The hole 17 is formed between the upper plate portion 1512 and the second mounting plate 152. The first mounting plate 151 is connected to the crossbeam 112 through the upper plate portion 1512 and to the second mounting plate 152 and the third mounting plate 153 through the lower plate portion 1513. This can simplify the structure of the mounting frame 15 and improve the production efficiency of the mounting frame 15.

[0048] In some embodiments, as Figure 3 As shown, the vehicle frame 11 has two substantially parallel longitudinal beams 111 , the front ends of the two longitudinal beams 111 are connected to the cross beam 112 , and there are two mounting brackets 15 . The two longitudinal beams 111 are respectively provided with a mounting bracket 15 on opposite sides along the width direction of the vehicle frame 11 , each mounting bracket 15 is used to install a traction ring 16 , and the two mounting brackets 15 are symmetrically arranged along the left-right direction of the vehicle frame 11 .

[0049] It can be understood that in some other embodiments, the third mounting plate body 153 can also be set to a structure basically the same as the second mounting plate body 152, that is, a rectangular hole groove 17 is also formed between the third mounting plate body 153 and the first mounting plate body 151, and the hole groove 17 of the third mounting plate body 153 and the hole groove 17 of the second mounting plate body 152 are arranged opposite to each other along the width direction of the frame 11 for the crossbeam 112 to pass through, which can increase the welding area between the third mounting plate body 153 and the crossbeam 112 and improve the torsional resistance of the mounting frame 15 relative to the crossbeam 112 in the width direction of the frame 11.

[0050] In addition, those skilled in the art can make various other corresponding changes and modifications based on the technical concept of this application, and all these changes and modifications should fall within the scope of protection of the claims of this application.
