Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to an all-terrain vehicle. Background Technology

[0002] All-terrain vehicles (ATVs) can operate in extremely harsh environments, including but not limited to beaches, mountains, forests, and swamps, and are widely used in agriculture, forestry operations, and recreation. The side doors of ATVs need to be opened or closed depending on the usage scenario to meet different needs such as ventilation or insulation.

[0003] Currently, in all-terrain vehicles, door handles are generally connected to the door lock via steel linkages. By pulling the door handle, the steel linkage transmits the force from the handle to the lock, thus unlocking the door. However, when the door assembly of an all-terrain vehicle deforms due to a collision or other reasons, the steel linkage is prone to deformation, making it difficult to transmit the force from the handle to the lock. This results in door handle failure and poor reliability. Summary of the Invention

[0004] In view of this, this application provides an all-terrain vehicle whose door handle assembly has high reliability.

[0005] Embodiments of this application provide an all-terrain vehicle, including a frame, body panels, a running gear, a power system, and a door assembly. The body panels are mounted on the frame and are substantially located on the outer periphery of the frame. The running gear is at least partially located under the frame, and the power system is supported by the frame and driven to the running gear. The door assembly includes a door body, a door lock, a handle, and a cable. The door body is rotatably connected to the frame, and the door lock and handle are located on the door body, with the handle connected to the door lock. The handle includes a handle body, an outer handle, and a handle spring. The handle body is located on the door body, and the outer handle includes a gripping portion, a rotating portion, and a pushing portion, which are interconnected and integrally formed. The rotating portion is rotatably connected to the handle body, the handle spring connects the gripping portion and the handle body, and the cable connects the pushing portion and the door lock. When the gripping portion is rotated away from the handle body, the pushing portion pulls the cable; after releasing the gripping portion, the handle spring drives the gripping portion to rotate toward the handle body and return to its original position.

[0006] Furthermore, the handle also includes a rotating component, which comprises a pressure-receiving part, a rotating part, and a follower part. The pressure-receiving part, the rotating part, and the follower part are interconnected and integrally formed. The rotating part is rotatably connected to the handle body, the pressure-receiving part abuts against the pushing part, and the follower part is connected to the cable. The rotation axes of the rotating part and the rotating part are inclined relative to each other. When the grip part is rotated away from the handle body, the pushing part pushes against the pressure-receiving part, causing the rotating part to drive the follower part to rotate, and the follower part pulls the cable.

[0007] Furthermore, the pressure-receiving part is provided with an abutment groove, and the pushing part is inserted into the abutment groove. The abutment groove can restrict the movement range of the pushing part relative to the pressure-receiving part.

[0008] Furthermore, the pushing part is provided with a locking groove, and the pressure receiving part is inserted into the locking groove. The locking groove can restrict the range of movement of the pressure receiving part relative to the pushing part.

[0009] Furthermore, the handle also includes a handle lock cylinder and a stop plate. The handle lock cylinder is rotatably mounted on the handle body, and the stop plate is connected to the handle lock cylinder. The outer handle also includes a locking part, which is integrally formed with the rotating part and has a locking groove. After the grip part is reset, the stop plate can be inserted into the locking groove to restrict the rotation of the grip part.

[0010] Furthermore, the direction in which the grip rotates toward the handle body is defined as the positive rotation direction. The handle body is provided with a support portion, which can stop the stop plate along the positive rotation direction when the stop plate is inserted into the locking slot.

[0011] Furthermore, the handle body is provided with a receiving groove, into which the grip portion can be accommodated. After the grip portion is reset, it is located within the receiving groove and does not extend out of the receiving groove, and there is a gap between the grip portion and the inner wall of the receiving groove for the hand to reach in.

[0012] Furthermore, the vehicle frame is equipped with a locking ring, and the door lock includes a lock housing, a lock body, a door lock spring washer, and a limiting assembly. The lock housing has an unlocked position and a locked position, and the lock body is located on the lock housing and rotates relative to the lock housing between the unlocked and locked positions. When the lock body rotates to the locked position, it engages with the locking ring; when the lock body rotates to the unlocked position, it disengages from the locking ring. The door lock spring connects the lock body and the lock housing and is used to drive the lock body to rotate towards the unlocked position. The limiting assembly is located on the lock housing and connects the cable to the lock body. The limiting assembly is used to limit the lock body to the locked position, and the handle releases the lock body by pulling the cable through the limiting assembly.

[0013] Furthermore, the limiting assembly includes a limiting member and a limiting elastic member. The limiting member is rotatably mounted on the lock housing and is connected to the pull cable. The limiting elastic member connects the limiting member and the lock housing. The limiting member has a pawl portion, the lock body has a ratchet portion, and the lock housing has an initial position. When the lock body rotates to the locked position, the limiting elastic member drives the limiting member to rotate toward the initial position and engages the pawl portion with the ratchet portion; when the pull cable drives the limiting member to rotate, the pawl portion disengages from the ratchet portion.

[0014] Furthermore, the limiting assembly also includes a trigger element, which is rotatably mounted on the lock housing. The trigger element has a first protrusion, and the limiting element has a second protrusion. The trigger element is connected to a cable. When the cable drives the trigger element to rotate, the first protrusion pushes against the second protrusion, causing the limiting element to rotate away from its initial position.

[0015] The all-terrain vehicle provided in this application, on the one hand, replaces the steel linkage with a flexible cable. Even if the cable deforms after the door assembly is deformed, the pushing part can still drive the cable to move, thereby unlocking the door lock. On the other hand, the outer handle is a one-piece, non-assembled structure, which improves the stability of the connection between the grip, rotating part, and pushing part, reducing the possibility that the outer handle will deform after the door assembly is impacted and fail to drive the cable. In summary, the door assembly and handle of the all-terrain vehicle provided in this application have high reliability and can reduce the probability of handle failure due to door assembly deformation after a collision.

Detailed Implementation

[0017] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0019] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0020] like Figure 1 As shown, the all-terrain vehicle 100 includes a frame 11, a body panel 12, a running gear 13, a power system (not shown), and door assemblies 14. The body panel 12 is mounted on the frame 11 and is substantially located around the outer periphery of the frame 11, forming a passenger compartment around it. The running gear 13 includes front wheels 131 located at the front end of the all-terrain vehicle 100 and rear wheels 132 located at the rear end of the all-terrain vehicle 100.

[0021] The power system is at least partially located on and supported by the frame 11. The power system is connected to the front wheel 131 and the rear wheel 132 to provide power to the front wheel 131 and the rear wheel 132 to drive the frame 11 to move.

[0022] like Figure 1 and Figure 2 As shown, the door assembly 14 includes a door body 141, a door lock 142, and a handle 143. A locking ring 111 is provided on the frame 11, and the door body 141 is rotatably connected to the frame 11. The door lock 142 and handle 143 are located on the door body 141. When the door body 141 rotates toward the frame 11, the door lock 142 engages with the locking ring 111, closing the passenger compartment. It can be understood that the side of the door body 141 along its thickness direction and closer to the passenger compartment is the inner side of the door body 141, and the other side is the outer side of the door body 141.

[0023] The door assembly 14 also includes a cable 144 that connects the handle 143 and the door lock 142 so that the handle 143 is connected to the door lock 142 so that the door lock 142 can be unlocked by the handle 143.

[0024] In some embodiments, such as Figure 2 and Figure 3 As shown, the handle 143 includes a handle body 1431, an outer handle 1432, and a handle elastic element 1433. The handle body 1431 is connected to the door body 141, and the outer handle 1432 is rotatably connected to the handle body 1431 and is located on the outside of the door body 141. The outer handle 1432 is connected to a cable 144.

[0025] Rotating the outer handle 1432 away from the handle body 1431 causes the outer handle 1432 to move the cable 144, which in turn pulls the door lock 142, thus unlocking the door lock 142 from outside the passenger compartment. The handle elastic element 1433 connects the outer handle 1432 and the handle body 1431; releasing the outer handle 1432 causes the handle elastic element 1433 to drive the outer handle 1432 to rotate toward the handle body 1431 and return to its original position.

[0026] The handle 143 also includes an inner handle 1434, which is rotatably connected to the door body 141 and located on the inside of the door body 141. The inner handle 1434 is connected to a cable 144. By rotating the inner handle 1434, the inner handle 1434 drives the cable 144 to move, causing the cable 144 to pull the door lock 142, thereby unlocking the door lock 142 from inside the passenger compartment.

[0027] In some embodiments, the cable 144 includes a door lock pull cord 1441, an outer handle pull cord 1442, and an inner handle pull cord 1443. The outer handle pull cord 1442 connects the outer handle 1432 and the door lock pull cord 1441, and the inner handle pull cord 1443 connects the inner handle 1434 and the door lock pull cord 1441. The door lock pull cord 1441 is connected to the vehicle door lock 142. Rotating either the outer handle 1432 or the inner handle 1434 will pull the door lock 142, thereby unlocking the door lock 142. In other embodiments, two cables 144 may be provided, one cable 144 connecting the outer handle 1432 and the door lock 142, and the other cable 144 connecting the inner handle 1434 and the door lock 142.

[0028] like Figure 3 and Figure 4 As shown, the outer handle 1432 includes a gripping portion 1432a, a rotating portion 1432b, and a pushing portion 1432c, which are interconnected and integrally formed. In some embodiments, the rotating portion 1432b is disposed between the gripping portion 1432a and the pushing portion 1432c.

[0029] In some embodiments, two rotating parts 1432b are provided, each located at one end of the grip 1432a, and the pushing part 1432c is connected to one of the rotating parts 1432b. The handle body 1431 has two connecting parts 1431a, and the two rotating parts 1432b are located between the two connecting parts 1431a. Each rotating part 1432b is rotatably connected to one connecting part 1431a via a pivot. The cable 144 is connected to the pushing part 1432c. When the grip 1432a is rotated, the rotating part 1432b drives the pushing part 1432c to rotate, thereby causing the pushing part 1432c to move the cable 144, thus unlocking the door lock 142.

[0030] The handle elastic element 1433 connects the rotating part 1432b and the handle body 1431. The handle elastic element 1433 is used to rotate the grip part 1432a toward the handle body 1431 to reset the grip part 1432a. Exemplarily, the handle elastic element 1433 is a torsion spring, and it is sleeved on the pivot of the rotating part 1432b. In other embodiments, the handle elastic element 1433 may be connected to either the grip part 1432a or the pushing part 1432c. Since the pushing part 1432c is connected to the grip part 1432a via the rotating part 1432b, when the handle elastic element 1433 is connected to either the pushing part 1432c or the rotating part 1432b, it can be understood that the handle elastic element 1433 is connected to the grip part 1432a.

[0031] The handle body 1431 has a receiving groove 1431b, which is located on the outside of the door body 141. The grip portion 1432a can be accommodated in the receiving groove 1431b, and after the grip portion 1432a is reset, it remains within the receiving groove 1431b and does not extend out of it. A gap is provided between the grip portion 1432a and the inner wall of the receiving groove 1431b for the hand to enter. By accommodating the grip portion 1432a in the receiving groove 1431b, the wind resistance of the all-terrain vehicle 100 can be reduced. When it is necessary to open the door body 141, the hand is inserted into the gap between the grip portion 1432a and the inner wall of the receiving groove 1431b, which engages the grip portion 1432a and causes it to rotate, thereby causing the push portion 1432c to drive the cable 144 to unlock the door lock 142.

[0032] In some embodiments, the handle 143 further includes a handle lock cylinder 1435 and a stop plate 1436. The handle lock cylinder 1435 is rotatably mounted on the handle body 1431, and the stop plate 1436 is connected to the handle lock cylinder 1435. By turning the handle lock cylinder 1435 with a key, the handle lock cylinder 1435 can drive the stop plate 1436 to rotate. In some embodiments, the rotation axis of the handle lock cylinder 1435 is parallel to the thickness direction of the door assembly 14, and the length direction of the stop plate 1436 extends radially along the rotation of the handle lock cylinder 1435.

[0033] The outer handle 1432 also includes a locking part 1432d, which is integrally formed with the rotating part 1432b. The locking part 1432d is provided with a locking groove 1432e. After the grip part 1432a is reset, the locking groove 1432e is aligned with the stop plate 1436. The stop plate 1436 can be inserted into the locking groove 1432e to restrict the rotation of the grip part 1432a, so that the door lock 142 cannot be unlocked by rotating the grip part 1432a.

[0034] For ease of description, the direction in which the grip 1432a rotates toward the handle body 1431 is defined as the forward rotation direction, and the direction in which the grip 1432a rotates away from the handle body 1431 is defined as the reverse rotation direction.

[0035] The handle body 1431 is provided with a support portion 1431c, which is located between the stop plate 1436 and the grip portion 1432a in the forward rotation direction. When the stop plate 1436 is inserted into the locking slot 1432e, the stop plate 1436 abuts against the support portion 1431c, so that the support portion 1431c can stop and support the stop plate 1436 in the forward rotation direction, thereby reducing the possibility of the stop plate 1436 bending and deforming due to the force on the grip portion 1432a. Exemplarily, the support portion 1431c and the connecting portion 1431a are integrally formed.

[0036] In some embodiments, the handle 143 further includes a rotating member 1437, which includes a pressure-receiving part 1437a, a rotating part 1437b, and a follower part 1437c. The pressure-receiving part 1437a, the rotating part 1437b, and the follower part 1437c are interconnected and integrally formed. The rotating part 1437b is located between the pressure-receiving part 1437a and the follower part 1437c. The rotating part 1437b is rotatably connected to the handle body 1431 via a pivot. The pressure-receiving part 1437a abuts against the pushing part 1432c. The follower part 1437c is connected to the cable 144 so that the cable 144 is connected to the pushing part 1432c.

[0037] When the gripping part 1432a rotates in the opposite direction of rotation, the pushing part 1432c pushes against the pressure-receiving part 1437a, causing the rotating part 1437b to drive the follower part 1437c to rotate, thereby causing the follower part 1437c to pull the cable 144. In some embodiments, the axial direction of the rotation axis of the rotating part 1437b is inclined to the axial direction of the rotation axis of the rotating part 1432b. With the above arrangement, the size of the handle 143 along the thickness direction of the door body 141 can be reduced, thereby reducing the thickness of the door body 141. Exemplarily, the axial direction of the rotation axis of the rotating part 1437b is parallel to the thickness direction of the door body 141, and the axial direction of the rotation axis of the rotating part 1432b is perpendicular to the axial direction of the rotation axis of the rotating part 1437b.

[0038] In some other embodiments, the rotating member 1437 may be omitted, and the cable 144 is connected to the pushing part 1432c so that the pushing part 1432c can drive the cable 144 to move.

[0039] like Figure 5As shown, the side wall of the pressure-receiving part 1437a facing the pushing part 1432c is provided with an abutment groove 1437d, and the side wall of the pushing part 1432c facing the pressure-receiving part 1437a is provided with a locking groove 1432f. The pushing part 1432c is inserted into the abutment groove 1437d and the pressure-receiving part 1437a is inserted into the locking groove 1432f. When the gripping part 1432a rotates, the pushing part 1432c can abut against the inner wall of the abutment groove 1437d on the side away from the rotating part 1437b, or the pressure-receiving part 1437a can abut against the inner wall of the locking groove 1432f on the side away from the rotating part 1432b. This limits the range of relative movement between the pushing part 1432c and the pressure-receiving part 1437a, thereby restricting the rotation range of the gripping part 1432a and reducing the probability of the pushing part 1432c disengaging from the pressure-receiving part 1437a. In some other embodiments, only the pressure-bearing part 1437a is provided with an abutment groove 1437d and the pushing part 1432c is inserted into the abutment groove 1437d, or only the pushing part 1432c is provided with a snap-fit ​​groove 1432f and the pressure-bearing part 1437a is inserted into the snap-fit ​​groove 1432f.

[0040] For example, the end of the pushing portion 1432c away from the rotating portion 1432b is protruding, and the protrusion extends toward the pressure-receiving portion 1437a, so that the protrusion and the pushing portion 1432c cooperate to form a locking groove 1432f. Similarly, the end of the pressure-receiving portion 1437a away from the rotating portion 1437b is protruding and extends toward the pushing portion 1432c to form an abutment groove 1437d.

[0041] In some embodiments, such as Figure 6 and Figure 7 As shown, the door lock 142 includes a lock housing 1421, a lock body 1422, a door lock elastic element 1423, and a limiting assembly 1424. The lock housing 1421 is disposed on the door body 141 of the door assembly 14. The lock housing 1421 has an unlocked position and a locked position; the lock body 1422 is disposed on the lock housing 1421 and can rotate relative to the lock housing 1421 between the unlocked position and the locked position. When the lock body 1422 rotates to the locked position, the lock body 1422 can engage with the lock ring 111; when the lock body 1422 rotates to the unlocked position, the lock body 1422 can disengage from the lock ring 111.

[0042] For example, the lock body 1422 is provided with a lock groove 1422a, which is used to receive a portion of the lock ring 111. When the lock body 1422 is in the locked position, the lock groove 1422a is located inside the lock housing 1421, and the lock groove 1422a limits the lock ring 111 to lock the connection between the door body 141 and the frame 11, thereby keeping the door body 141 closed.

[0043] like Figure 7 and Figure 8As shown, when the lock body 1422 is in the unlocked position, the lock groove 1422a connects to the outside of the lock housing 1421, allowing the lock ring 111 to disengage from the lock groove 1422a, thereby unlocking the connection between the door body 141 and the frame 11, and allowing the door body 141 to be opened. The door lock elastic member 1423 connects the lock body 1422 and the lock housing 1421, and the door lock elastic member 1423 applies force to the lock body 1422, causing the lock body 1422 to tend to rotate toward the unlocked position.

[0044] A limiting component 1424 is disposed on the lock housing 1421 and connects the cable 144 to the lock body 1422. The limiting component 1424 can limit the lock body 1422 to the locked position, thereby locking the door body 141. When the occupant rotates the grip 1432a to move the cable 144, the cable 144 drives the limiting component 1424 to release the lock body 1422. The released lock body 1422 rotates toward the unlocked position under the drive of the door lock elastic element 1423 to unlock the door body 141. Exemplarily, the door lock elastic element 1423 is a torsion spring and is coaxially arranged with the rotation axis of the lock body 1422.

[0045] In some embodiments, such as Figures 7 to 9 As shown, the limiting component 1424 includes a limiting member 1424a and a limiting elastic member 1424b.

[0046] The lock housing 1421 has an initial position. A limiting member 1424a is disposed on the lock housing 1421 and is rotatable relative to the lock housing 1421. The limiting member 1424a is connected to a cable 144, which can drive the limiting member 1424a to rotate away from the initial position. A limiting elastic member 1424b connects the limiting member 1424a to the lock housing 1421. When the lock body 1422 rotates to the locked position, the limiting elastic member 1424b drives the limiting member 1424a to rotate toward the initial position.

[0047] The limiting member 1424a is provided with a pawl portion 1424c, and the lock body 1422 is provided with a ratchet portion 1422b. When the limiting member 1424a is in the initial position, the pawl portion 1424c engages with the ratchet portion 1422b to limit the lock body 1422 to the locked position; when the cable 144 drives the limiting member 1424a to rotate away from the initial position, the pawl portion 1424c disengages from the ratchet portion 1422b, thereby releasing the lock body 1422 and allowing the lock body 1422 to rotate toward the unlocked position under the drive of the door lock elastic member 1423.

[0048] In some embodiments, such as Figure 7 , Figure 9 and Figure 10As shown, the limiting assembly 1424 also includes a trigger 1424d, which is rotatably connected to the lock housing 1421. The trigger 1424d is connected to a pull cable 144 so that the pull cable 144 is connected to the limiting member 1424a. The trigger 1424d has a first protrusion 1424e, and the limiting member 1424a has a second protrusion 1424f. When the pull cable 144 drives the trigger 1424d to rotate, the first protrusion 1424e applies pressure to the second protrusion 1424f to drive the limiting member 1424a away from its initial position, thereby unlocking the door lock 142.

[0049] Optionally, the pivots of the limiting member 1424a and the lock body 1422 are substantially parallel and substantially perpendicular to the pivot of the trigger member 1424d, thereby changing the direction of force transmission and reducing the size of the door lock 142 in the thickness direction of the door assembly 14.

[0050] Specifically, such as Figures 9 to 11 As shown, during use, when the door lock 142 locks the door body 141, the cable 144 drives the trigger 1424d to rotate, causing the door lock 142 to be in the unlocked state, thereby opening the door body 141. When the door body 141 is opened and the outer handle 1432 is released, the limiting member 1424a is reset under the drive of the limiting elastic member 1424b, and drives the trigger 1424d to reset, so that the pawl 1424c abuts against the ratchet 1422b. At this time, the lock groove 142 of the lock body 1422... 2a is exposed so that when the door body 141 is closed, the locking ring 111 automatically enters the lock groove 1422a. As the door body 141 closes, the locking ring 111 drives the lock body 1422 to rotate to the locked position. At this time, the ratchet 1422b pushes the pawl 1424c, causing the limiting member 1424a to rotate a certain angle towards its initial position, allowing the ratchet 1422b to pass over the pawl 1424c. Ultimately, the pawl 1424c engages with the ratchet 1422b, and the door lock 142 is locked. Exemplarily, the limiting elastic member 1424b is a torsion spring and is coaxially arranged with the limiting member 1424a.

[0051] Optionally, an elastic element can also be provided at the pivot of the trigger 1424d to drive the trigger 1424d to reset, so that the first protrusion 1424e actively disengages from the second protrusion 1424f.
