[0033] Figure 1The dashed boxes in FIG. 1 respectively represent the range of the front part 15, the seating part 16 and the rear part 17 of the ATV 100. It is to be understood that in other embodiments, each of the dashed boxes representing the front part 15, the seating part 16 and the rear part 17 of the ATV 100 can also be of other shapes; in other embodiments, each of the dashed boxes representing the front part 15, the seating part 16 and the rear part 17 of the ATV 100 can also be at other positions.

[0034] The front part 15 and / or the rear part 17 of the ATV 100 is provided with a bumper 18. It is to be understood that either one or both of the front end of the front part 15 of the ATV 100 and the rear end of the rear part 17 of the ATV 100 is provided with the bumper 18, and the following description takes the front end of the front part 15 as an example.

[0035] With reference to Figure 2 and Figure 3 , the bumper 18 comprises a connecting assembly 181 and a telescopic assembly 182. In some embodiments, the telescopic assembly 182 is provided in two sets, and the two sets of the telescopic assembly 182 are oppositely arranged on the left and right sides of the longitudinal center plane 101 along the left-right direction; alternatively, the two sets of the telescopic assembly 182 are symmetrically arranged about the longitudinal center plane 101. The connecting assembly 181 is substantially arranged at the position of the width center of the front end of the front part 15 of the ATV 100, and the two sets of the telescopic assembly 182 are connected with the connecting assembly 181.

[0036] The telescopic assembly 182 is substantially in the shape of a long strip, and the length direction of the telescopic assembly 182 is substantially arranged along the left-right direction; the telescopic assembly 182 has an extended state and a retracted state, and when the telescopic assembly 182 is switched from the extended state to the retracted state, the length of the telescopic assembly 182 is shortened, so that the overall length of the bumper 18 along the left-right direction is shortened. It is to be understood that in other embodiments, the telescopic assembly 182 can also be provided in one set, and the set of the telescopic assembly 182 is arranged on the left side or the right side of the connecting assembly 181. In this way, the overall length of the bumper 18 along the left-right direction can also be adjusted, and the adaptability of the bumper 18 is better, thereby improving the passability of the ATV 100.

[0037] In some embodiments, the connecting assembly 181 comprises a first connecting rod 1811, a second connecting rod 1812 and a plurality of butt rods 1813. The first connecting rod 1811 and the second connecting rod 1812 are substantially parallel to the left-right direction, and the first connecting rod 1811 and the second connecting rod 1812 are arranged in the up-down direction with a spacing, the first connecting rod 1811 is above the second connecting rod 1812, and the first connecting rod 1811 and the second connecting rod 1812 are both fixedly connected with the frame 11.

[0038] In some embodiments, the number of telescopic assemblies 182 in each group is two, and the two telescopic assemblies 182 in each group are respectively a first telescopic assembly 182 and a second telescopic assembly 182. For example, the first telescopic assembly 182 in each group is located above the second telescopic assembly 182 in the group. The docking rod 1813 corresponds to the telescopic assembly 182 one by one, the first telescopic assembly 182 is connected with the corresponding docking rod 1813, and the docking rod 1813 is fixedly connected with the first connecting rod 1811. The second telescopic assembly 182 is connected with the corresponding docking rod 1813, and the docking rod 1813 is fixedly connected with the second connecting rod 1812. In other embodiments, the docking rod 1813 can be omitted, the first telescopic assembly 182 is fixedly connected with the first connecting rod 1811, and the second telescopic assembly 182 is fixedly connected with the second connecting rod 1812. In other embodiments, the connecting assembly 181 can also be a single rod or a grid shape.

[0039] In some embodiments, the vehicle body cover 12 at least partially covers the first connecting rod 1811 and the second connecting rod 1812, and the docking rod 1813 and the telescopic assembly 182 are exposed. The vehicle body cover 12 at the front end wall of the vehicle head part 15 is provided with a trailer opening 121 in the front-rear direction, and the trailer opening 121 is located between the first connecting rod 1811 and the second connecting rod 1812 in the height direction of the all-terrain vehicle 100. The all-terrain vehicle 100 further comprises a winch device (not shown in the figure), which comprises a traction assembly and a traction rope. The traction assembly is arranged on the side of the connecting assembly 181 close to the seating part 16 (see Figure 1 ) of the all-terrain vehicle 100 in the front-rear direction and is connected with the vehicle frame 11 or the connecting assembly 181; and the traction rope passes between the first connecting rod 1811 and the second connecting rod 1812 and is led out forwardly from the trailer opening 121. The first connecting rod 1811 and the second connecting rod 1812 have a certain protection effect on the traction assembly.

[0040] For example, the traction assembly comprises a base connected with the vehicle frame 11, a rotating roller rotatably arranged on the base, and a driving motor connected with the base. The driving motor is connected with the rotating roller to drive the rotating roller to rotate, and the traction rope is wound on the rotating roller. When the rotating roller rotates forwardly, the rotating roller winds the traction rope, and when the rotating roller rotates reversely, the rotating roller unwinds the traction rope.

[0041] In some embodiments, the all-terrain vehicle 100 further comprises an electrical system 19, which comprises a headlamp assembly 191 connected with the vehicle head part 15 of the all-terrain vehicle 100. The headlamp assembly 191 is provided with two, and the two headlamp assemblies 191 are symmetrically arranged on the left and right sides of the vehicle head part 15 and are connected with the vehicle body cover 12. In other embodiments, the headlamp assembly 191 can also be connected with the vehicle frame 11.

[0042] The first telescopic assembly 182 and the second telescopic assembly 182 in one group of telescopic assemblies 182 are respectively arranged on the upper and lower sides of one of the headlamp assemblies 191, and the first telescopic assembly 182 and the second telescopic assembly 182 in the other group of telescopic assemblies 182 are respectively arranged on the upper and lower sides of the other headlamp assembly 191. It can be understood that, in the front-rear direction, the telescopic assemblies 182 are located on the front side of the headlamp assemblies 191, and the first telescopic assembly 182 and the second telescopic assembly 182 in the same group jointly protect the corresponding headlamp assembly 191. In other embodiments, the telescopic assemblies 182 in each group can also be one or three or more.

[0043] With reference to Figure 2 and Figure 3 In some embodiments, the length direction of the first telescopic assembly 182 in the same group is relatively inclined to the length direction of the second telescopic assembly 182, the distance between the first telescopic assembly 182 and the second telescopic assembly 182 in the same group gradually decreases in the up-down direction along the left-right direction and away from the longitudinal center plane 101, and the projection of the first telescopic assembly 182 and the second telescopic assembly 182 in the same group in the transverse reference plane 102 along the length direction of the ATV 100 at least partially overlaps when the first telescopic assembly 182 and the second telescopic assembly 182 are both in the extended state. It can be understood that the angle a between the length direction of the first telescopic assembly 182 and the length direction of the second telescopic assembly 182 in the same group is within 30°, and exemplarily, a can take any value of 3°, 5°, 8°, 10°, 15°, 20°, 26°, or 30°.

[0044] With reference to Figure 4 When the first telescopic assembly 182 and the second telescopic assembly 182 are both in the extended state, the first telescopic assembly 182 and the second telescopic assembly 182 in the same group substantially jointly surround the corresponding headlamp assembly 191 in a ring shape, which can reduce the possibility of branches of grass and trees in contact with the headlamp assembly 191 along the horizontal direction and in the left-right direction, so that the first telescopic assembly 182 and the second telescopic assembly 182 in the same group have better protection effect on the corresponding headlamp assembly 191. Alternatively, when the first telescopic assembly 182 and the second telescopic assembly 182 are both in the extended state, the first telescopic assembly 182 and the second telescopic assembly 182 in the same group are arranged in mutual intersection and mutual non-contact. In other embodiments, when the first telescopic assembly 182 and the second telescopic assembly 182 are both in the extended state, the end of the first telescopic assembly 182 away from the corresponding docking rod 1813 and the end of the second telescopic assembly 182 away from the corresponding docking rod 1813 can be in contact with each other.

[0045] In some embodiments, the electric appliance system 19 further comprises a rear tail lamp assembly (not shown) connected to the rear portion 17 of the all-terrain vehicle 100. The mounting structure of the rear tail lamp assembly and the position of the rear tail lamp assembly relative to the rear bumper 18 provided on the rear portion 17 of the all-terrain vehicle 100 can be referred to the description of the headlamp assembly 191 above. In this way, the bumper 18 provided on the rear portion 17 of the all-terrain vehicle 100 can protect the rear tail lamp assembly.

[0046] Referring to Figure 3 In some embodiments, the telescopic assembly 182 comprises a fixed member 1821, a telescopic member 1822 and a limiting member 1823. Optionally, the fixed member 1821 and the telescopic member 1822 are both in the shape of a long strip. For example, the fixed member 1821 and the telescopic member 1822 are both in the shape of a hollow tube. The length direction of the fixed member 1821 and the telescopic member 1822 is substantially along the left-right direction. One end of the fixed member 1821 close to the longitudinal center plane 101 is fixedly connected to the corresponding docking rod 1813 along the left-right direction. In some embodiments, the fixed member 1821 and the docking rod 1813 are formed by bending a same rod or tube. In other embodiments, the telescopic member 1822 and the fixed member 1821 can be connected by a sliding rail or other structure.

[0047] The telescopic member 1822 is inserted into the fixed member 1821 and can slide relative to the fixed member 1821 along the length direction of the fixed member 1821. It can be understood that when the telescopic assembly 182 is switched from the extended state to the retracted state, the telescopic member 1822 slides towards the longitudinal center plane 101. The limiting member 1823 connects the telescopic member 1822 and the fixed member 1821 and fixes the telescopic member 1822 to the fixed member 1821, so that the telescopic member 1822 remains fixed after moving to a predetermined position.

[0048] Referring to Figure 2 and Figure 4In the extended state of the telescopic assembly 182, the distance between the end of the telescopic part 1822 away from the fixed part 1821 along the left-right direction and the longitudinal center plane 101 along the left-right direction is L1, half of the width of the front part 15 of the ATV 100 is L2, and half of the maximum width of the ATV 100 is L3. It can be understood that L3 is greater than or equal to L2. In some embodiments, L1 is greater than L2, so that the telescopic part 1822 at least extends beyond the front part 15 along the left-right direction, and the bumper 18 can better protect the front part 15. Alternatively, L1 is greater than L3, so that the bumper 18 can better protect the ATV 100. It can be understood that in the embodiments in which the bumper 18 is arranged at the rear part 17 of the ATV 100, the corresponding distance between the end of the telescopic part 1822 away from the fixed part 1821 along the left-right direction and the longitudinal center plane 101 along the left-right direction is greater than or equal to half of the width of the rear part 17.

[0049] In some embodiments, in the retracted state of the telescopic assembly 182, the distance between the end of the telescopic part 1822 away from the fixed part 1821 along the width direction of the ATV 100 and the longitudinal center plane 101 along the width direction of the ATV 100 is L4, and L4 is less than or equal to L3. In the retracted state of the telescopic assembly 182, the telescopic part 1822 does not extend beyond the body structure of the ATV 100 along the left-right direction, so as to facilitate the ATV 100 to pass through a relatively narrow road section. In other embodiments, L4 can be greater than L2 or greater than L3, as long as L4 is less than L1.

[0050] Referring to Figures 5 to 7In some embodiments, the limiting member 1823 includes a protruding portion 1823a and an elastic portion 1823b, the elastic portion 1823b includes an elastic connecting rod 1823c, an abutting connecting rod 1823d, and a connecting end cover 1823e, the elastic connecting rod 1823c and the abutting connecting rod 1823d are substantially parallel and spaced apart, and the same end of the elastic connecting rod 1823c and the abutting connecting rod 1823d is fixedly connected with the connecting end cover 1823e. At least part of the elastic connecting rod 1823c and the abutting connecting rod 1823d are inserted into the telescopic member 1822 from one end of the telescopic member 1822 away from the fixed member 1821, and the elastic connecting rod 1823c and the abutting connecting rod 1823d respectively abut the opposite sides of the inner wall of the telescopic member 1822, so that the elastic connecting rod 1823c is relatively fixed with the telescopic member 1822. The circumferential wall of the telescopic member 1822 is provided with a clearance hole 1822a in the wall thickness direction of the telescopic member 1822, the circumferential wall of the fixed member 1821 is provided with a limiting hole 1821a in the wall thickness direction of the fixed member 1821, and the protruding portion 1823a is provided in the elastic connecting rod 1823c and is inserted into the clearance hole 1822a. The limiting hole 1821a is spaced apart by at least two along the length direction of the fixed member 1821, and the protruding portion 1823a can be aligned with each limiting hole 1821a and inserted into the corresponding limiting hole 1821a during the sliding process of the telescopic member 1822 relative to the fixed member 1821, so as to limit the movement of the telescopic member 1822. Exemplarily, the elastic connecting rod 1823c, the abutting connecting rod 1823d, the elastic protrusion, and the connecting end cover 1823e are integrally injection molded.

[0051] Taking the case of two limiting holes 1821a, two protruding portions 1823a are provided, when the telescopic assembly 182 is in the retracted state, the protruding portions 1823a correspond one by one to the limiting holes 1821a, and each protruding portion 1823a is inserted into the corresponding limiting hole 1821a. When the telescopic assembly 182 switches from the retracted state to the extended state, the protruding portion 1823a can be pressed, so that the elastic connecting rod 1823c is deformed, and the protruding portion 1823a is separated from the limiting hole 1821a; then the telescopic member 1822 is moved away from the fixed member 1821, when the protruding portion 1823a located close to the fixed member 1821 is aligned with the limiting hole 1821a located away from the fixed member 1821, the deformation of the elastic connecting rod 1823c is restored, so that the protruding portion 1823a is inserted into the corresponding limiting hole 1821a, and the telescopic assembly 182 is in the extended state at this time. In other embodiments, the number of protruding portions 1823a can be one. In other embodiments, the limiting holes 1821a can be spaced apart by three or more along the length direction of the fixed member 1821, in this way, by making the protruding portion 1823a cooperate with each limiting hole 1821a in turn, the telescopic assembly 182 can have more length adjustment range.

[0052] In some embodiments, the abutment link 1823d has the same shape and size as the elastic link 1823c, and the abutment link 1823d is provided with the same protrusion 1823a. The telescopic member 1822 is also provided with a clearance hole 1822a at the corresponding position, and the fixing member 1821 is provided with a limiting hole 1821a at the corresponding position. This configuration can improve the stability of fixing the telescopic member 1822.

[0053] In some embodiments, the inner diameter of the connecting end cap 1823e is equal to the outer diameter of the fixing member 1821. When the telescopic assembly 182 is in the retracted state, the connecting end cap 1823e is fitted onto the fixing member 1821, providing a certain degree of protection for the telescopic assembly 1822. When it is necessary to switch the telescopic assembly 182 from the retracted state to the extended state, after the protrusion 1823a separates from the limiting hole 1821a, the telescopic assembly 1822 can be moved by pulling the connecting end cap 1823e, causing the protrusion 1823a to abut against the inner wall of the clearance hole 1822a. In other embodiments, the inner diameter of the connecting end cap 1823e may be equal to the outer diameter of the telescopic assembly 1822, so that the connecting end cap 1823e is fitted onto the telescopic assembly 1822, providing a certain degree of protection for the interior of the telescopic assembly 1822. In other embodiments, the connecting end cap 1823e may also be inserted into the telescopic member 1822 to seal the opening at the corresponding end of the telescopic member 1822. It should be noted that the "inner diameter" or "outer diameter" here is not intended to limit the cross-section of the fixing member 1821, the telescopic member 1822, and the connecting end cap 1823e to be circular. In fact, the cross-section of the fixing member 1821, the telescopic member 1822, and the connecting end cap 1823e may also be square, elliptical, or other shapes, as long as the connecting end cap 1823e can be fitted onto the fixing member 1821 or the telescopic member 1822.

[0054] In other embodiments, the connecting end cap 1823e may be omitted, and the resilient link 1823c and the abutment link 1823d may be connected to each other.

[0055] Reference Figure 8In some embodiments, the elastic part 1823b includes an elastic connecting rod 1823c and a connecting end cap 1823e. The elastic connecting rod 1823c is inserted into the telescopic member 1822 and connected to the connecting end cap 1823e. The connecting end cap 1823e is sleeved on the telescopic member 1822. A clearance hole 1822a is provided through the peripheral wall of the telescopic member 1822 along the wall thickness direction. A protrusion 1823a is provided on the elastic connecting rod 1823c and inserted into the clearance hole 1822a. When the telescopic member 1822 slides, the protrusion 1823a can be inserted into the limiting hole 1821a. By connecting the connecting end cap 1823e to the telescopic member 1822, the elastic connecting rod 1823c is relatively fixed to the telescopic member 1822, so that the elastic connecting rod 1823c can undergo elastic deformation when the protrusion 1823a is pressed.

[0056] In other embodiments, the elastic portion 1823b may also be a spring, with the protrusion 1823a inserted into the relief hole 1822a, and the two ends of the spring abutting against the protrusion 1823a and the telescopic member 1822, respectively. Exemplarily, the structure in which the protrusion 1823a and the elastic portion 1823b cooperate with each other forms a spring pin structure.

[0057] In other embodiments, the elastic portion 1823b may be provided on the fixing member 1821, and the limiting hole 1821a may be provided on the telescopic member 1822. Exemplarily, the telescopic member 1822 is sleeved on the fixing member 1821 and can slide along the length direction of the fixing member 1821. The specific structure can be referred to the description above, and will not be repeated here.

[0058] In other embodiments, the limiting member 1823 may also be other structures that can fix the telescopic member 1822. For example, the limiting member 1823 is a screw, and the peripheral wall of the fixing member 1821 is provided with a threaded hole. The screw is threadedly engaged with the threaded hole. By rotating the screw, the screw can be pressed against the outer peripheral wall of the telescopic member 1822 to fix the telescopic member 1822.

[0059] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
