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

[0002] An all-terrain vehicle is a vehicle capable of adapting to various complex terrains such as grasslands and beaches, and is widely used in outdoor entertainment or rescue, agricultural production and other fields.

[0003] The all-terrain vehicle generally has a door, and the door is provided with a door lock. The door lock cooperates with a lock hook arranged on the vehicle frame, so that the door is fixed with the vehicle frame, thereby playing a protective effect on the driver and passenger in the passenger compartment.

[0004] At present, the vehicle frame of the all-terrain vehicle generally reserves a mounting position for mounting the lock hook. When the lock hook is mounted in the corresponding mounting position, the height of the locking tongue of the door lock is sometimes higher or lower than the height of the lock hook due to the installation error of the lock hook itself or the error during assembly of the door or the error during assembly of the door lock, so that the door lock is difficult to be clamped into the lock hook. At this time, it is necessary to adjust the mounting position of the lock hook or the door or the door lock, and sometimes even the shape of the door needs to be corrected, resulting in relatively complicated assembly operation of the all-terrain vehicle. CONTENT OF THE INVENTION

[0007] In some embodiments of the present application, the fixed seat is provided with an abutting piece on both sides along the height direction of the vehicle frame, and the elastic piece is provided with two ends abutting against the abutting pieces and the floating seat; when the door is in the open state, the lock tongue is separated from the lock hook, and the floating seat is located at a preset position.

[0008] In some embodiments of the present application, the fixed seat is provided with a receiving groove along the height direction thereof, and the floating seat and the elastic piece are located at least partially in the receiving groove; one of the inner side wall of the receiving groove and the floating seat is provided with a limiting groove along the height direction of the vehicle frame, and the other is provided with a limiting protrusion, which is in sliding fit with the limiting groove along the height direction of the vehicle frame.

[0009] In some embodiments of the present application, the fixed seat is provided with an opening at at least one end of the receiving groove, which is arranged along the height direction of the vehicle frame and communicates with the inside of the receiving groove, and the floating seat is inserted into the receiving groove through the opening.

[0010] In some embodiments of the present application, the limiting protrusion is a ball, which is rotationally connected with the inner side wall of the corresponding receiving groove or the floating seat.

[0011] In some embodiments of the present application, the lock hook comprises a connecting portion and a clamping portion connected with the connecting portion, the connecting portion is detachably connected with the floating seat, and the clamping portion is matched with the lock tongue.

[0012] In some embodiments of the present application, the connecting portion is threadedly connected with the floating seat or is clamped or connected through a screw.

[0013] In some embodiments of the present application, the lock hook assembly further comprises a locking piece, which is located at least partially between the fixed seat and the floating seat, and the locking piece can lock the lock hook at any position matched with the lock tongue.

[0014] In some embodiments of the present application, the fixed seat is provided with an abutting screw hole, the axial direction of which intersects with the sliding direction of the floating seat; the locking piece comprises an abutting stud, which is threadedly connected with the inner wall of the abutting screw hole and can abut against the floating seat.

[0016] The all-terrain vehicle of the present application is assembled, and the elastic member can elastically limit the floating seat to an initial position. When the door body and the hook assembly are assembled to the vehicle frame respectively, if there is a deviation between the hook and the latch in the height direction of the vehicle frame, during the process of closing the door body, the latch of the door lock in the unlocked state contacts the hook, so that the hook is forced to move upward or downward within the preset range under the action of the latch, until the hook is clamped into the latch. Similarly, during the process of opening the door body, the hook moves upward or downward with the floating seat under the action of the latch, so that the latch can smoothly separate from the hook. Therefore, after the installation of the hook assembly or the door body is completed, even if there is a deviation between the hook and the latch in the height direction of the vehicle frame, the latch can still be connected with the hook, so that it is not necessary to adjust the installation position of the fixed seat of the hook assembly or the door lock or the door body, thereby reducing the requirement for the installation precision of the hook assembly or the door body or the door lock, and making the assembly operation of the all-terrain vehicle more convenient.

[0031] With reference to Figure 2 And Figure 3 The shackle assembly 153 comprises a fixed seat 1531, a floating seat 1532, a shackle 1533 and an elastic member 1534. The fixed seat 1531 is fixedly connected with the frame 11 by bolts; in other embodiments, the fixed seat 1531 can also be connected with the frame 11 by welding or by other means.

[0032] The side wall of the side of the fixed seat 1531 away from the frame 11 is provided with a containing groove 1531a in the up-down direction, and the inner side walls of the two sides of the containing groove 1531a in the width direction thereof are each provided with a limiting groove 1531b in the up-down direction. In some embodiments, the fixed seat 1531 is provided with an opening 1531c at the upper end and the lower end of the containing groove 1531a in the up-down direction, and the opening 1531c communicates with the containing groove 1531a and the limiting groove 1531b.

[0033] The floating seat 1532 is arranged in the containing groove 1531a, and the floating seat 1532 is provided with limiting protrusions 1532a on the side walls of the two sides thereof in the width direction of the containing groove 1531a, and the limiting protrusions 1532a are in the shape of a long strip. When the shackle assembly 153 is assembled, the floating seat 1532 can be inserted into the containing groove 1531a from the opening 1531c at the upper end or the lower end of the fixed seat 1531, and the limiting protrusions 1532a are inserted into the limiting grooves 1531b. The limiting protrusions 1532a are in sliding fit with the limiting grooves 1531b in the up-down direction, so that the floating seat 1532 and the fixed seat 1531 can be stably connected in sliding fit. In other embodiments, the floating seat 1532 and the fixed seat 1531 can also be connected in sliding fit through a slide rail or a linear bearing and the like.

[0034] The fixed seat 1531 is provided with abutting pieces 1531d, and two abutting pieces 1531d are provided. The two abutting pieces 1531d are respectively arranged at the upper and lower ends of the fixed seat 1531 and respectively cover the openings 1531c located at the corresponding positions; alternatively, the abutting pieces 1531d are clamped on the fixed seat 1531. In other embodiments, the abutting pieces 1531d can be fixedly connected with the fixed seat 1531 by screws or by welding and the like. In other embodiments, only one of the upper end and the lower end of the fixed seat 1531 is provided with an opening 1531c, and the opening 1531c is used for inserting the floating seat 1532 into the accommodation groove 1531a.

[0035] As an implementation manner, the elastic pieces 1534 can be provided with 1, 2 or more. Hereinafter, taking the elastic pieces 1534 provided with 2 as an example, the elastic pieces 1534 correspond to the abutting pieces 1531d one by one, and each elastic piece 1534 is located between the floating seat 1532 and the corresponding abutting piece 1531d, and the two ends of the elastic piece 1534 are respectively abutted on the floating seat 1532 and the corresponding abutting piece 1531d. It can be understood that the floating seat 1532 can slide relative to the fixed seat 1531 in the up-down direction within a preset range 1531e. Figure 2 The large dashed box in the figure is used to represent the preset range 1531e. In other embodiments, the dashed box used to represent the preset range 1531e can also be of other shapes.

[0036] The fixed seat 1531 is provided with a preset position 1531f; in some embodiments, the elastic pieces 1534 are springs, and each elastic piece 1534 is elastically compressed and deformed, so that the upper and lower ends of the floating seat 1532 are subjected to the thrust of the corresponding elastic piece 1534, so that the floating seat 1532 is stationary at the preset position 1531f relative to the fixed seat 1531. It can be understood that the preset position 1531f is the initial position of the floating seat 1532 relative to the fixed seat 1531 after the hook assembly 153 is assembled and installed on the vehicle frame 11. In other embodiments, a stop structure can be arranged on the fixed seat 1531, and the floating seat 1532 is stationary at the preset position 1531f by the cooperation of the stop structure and the elastic piece 1534, and the stop structure allows the floating seat 1532 to only slide upward or downward relative to the fixed seat 1531.

[0037] Figure 2 The lower dashed box in the large dashed box in the figure is used to represent the preset position 1531f; in other embodiments, the dashed box used to represent the preset position 1531f can also be of other shapes. In other embodiments, the dashed box used to represent the preset position 1531f can also be at the upper position or the lower position of the fixed seat 1531.

[0038] The accommodating groove 1531a is used to accommodate the floating seat 1532 and the elastic member 1534, and has a certain protection effect on the floating seat 1532 and the elastic member 1534. In other embodiments, the accommodating groove 1531a can be omitted, and the limiting groove 1531b is arranged on the side wall of the fixed seat 1531.

[0039] In some embodiments, the upper and lower ends of the floating seat 1532 are each provided with an embedded groove 1532b, and one end of each elastic member 1534 close to the floating seat 1532 is inserted into the corresponding embedded groove 1532b. The embedded groove 1532b has a limiting effect on the elastic member 1534, which can improve the stability of the position of the elastic member 1534 relative to the floating seat 1532, thereby reducing the risk of the elastic member 1534 disengaging from the floating seat 1532.

[0040] In other embodiments, the elastic member 1534 can also be other elastic structural members, such as rubber pads, etc.

[0041] Referring to Figure 2 and Figure 4 , the locking hook 1533 is connected with the floating seat 1532 and can move with the floating seat 1532 within the preset range 1531e, and the locking hook 1533 protrudes to the outside of the accommodating groove 1531a. If the height of the locking hook 1533 is higher or lower than the height of the locking tongue 1521, when the vehicle door body 151 switches from the open state to the closed state, i.e. during the process of closing the vehicle door body 151, the locking tongue 1521 can contact the locking hook 1533, so that the locking hook 1533 is forced to move with the floating seat 1532, so that the height of the locking hook 1533 is equal to the height of the locking tongue 1521, and the locking tongue 1521 and the locking hook 1533 are smoothly matched. At this time, the locking tongue 1521 fixes the locking hook 1533 and the vehicle door body 151 is in the closed state; when the vehicle door body 151 switches from the closed state to the open state, i.e. during the process of opening the vehicle door body 151, the locking tongue 1521 acts, and the locking hook 1533 can move synchronously to facilitate the smooth separation of the locking tongue 1521 and the locking hook 1533. It can be understood that when the vehicle door body 151 is in the open state, the locking tongue 1521 and the locking hook 1533 are separated, and the floating seat 1532 is located at the preset position 1531f. Exemplarily, the locking tongue 1521 and the locking hook 1533 are matched by clamping.

[0042] In addition, when the position of the door lock 152 is displaced due to the long-term effect of its own gravity or due to a collision, since the position of the locking hook 1533 can be moved upward or downward under the action of the locking tongue 1521, the vehicle door body 151 can still be smoothly opened or closed, which can improve the reliability of the vehicle door body 151.

[0043] In other embodiments, the elastic member 1534 is arranged on the side wall of the floating seat 1532. Figure 1In the open state, the two elastic members 1534 can also be in a state of tensile deformation. In other embodiments, the upper elastic member 1534 can be in a natural state, that is, an undeformed state, and the lower elastic member 1534 can be in a state of compression deformation. In other embodiments, the number of elastic members 1534 can also be one, and the elastic member 1534 is arranged on the upper side or the lower side of the floating seat 1532; when the vehicle door body 151 is in an open state, the elastic force of the elastic member 1534 on the floating seat 1532 is used to balance the gravity of the floating seat 1532, so that the floating seat 1532 is stationary at the preset position 1531f.

[0044] Referring to Figure 5 In some embodiments, the limiting protrusion 1532a is arranged on the inner side wall of the accommodating groove 1531a, and the limiting groove 1531b is arranged on the floating seat 1532 in the up-down direction. When the floating seat 1532 is inserted into the accommodating groove 1531a through the opening 1531c, the limiting groove 1531b and the limiting protrusion 1532a are in sliding cooperation, so that the floating seat 1532 and the fixed seat 1531 are stably in sliding cooperation.

[0045] In some embodiments, the floating seat 1532 includes a pulley 1532c and a main body 1532d. The pulley 1532c is arranged in multiple in the up-down direction, and the pulley 1532c is rotationally connected to the main body 1532d through a pin shaft. The wheel groove on the circumferential wall of the pulley 1532c forms the limiting groove 1531b, and the cross section of the limiting groove 1531b is arc-shaped. The locking hook 1533 is connected to the main body 1532d. The surface of the limiting protrusion 1532a is arc-shaped. When the locking hook 1533 drives the pulley 1532c to slide under the action of the locking tongue 1521, the pulley 1532c can rotate around its own rotation axis, thereby facilitating the movement of the locking hook 1533 relative to the fixed seat 1531. Illustratively, the inner side wall of the accommodating groove 1531a is provided with a mounting groove 1531g in the up-down direction, the limiting protrusion 1532a is cylindrical, and the limiting protrusion 1532a is inserted into the mounting groove 1531g in the up-down direction and is in interference fit with the mounting groove 1531g. The limiting protrusion 1532a partially protrudes from the mounting groove 1531g and cooperates with the limiting groove 1531b.

[0046] Referring to Figure 6In some embodiments, the limiting protrusion 1532a is a ball 1532e, which is rotatably connected with the inner side wall of the corresponding accommodating groove 1531a or the floating seat 1532. For example, the side wall of the floating seat 1532 is provided with a groove 1532f, and part of the ball 1532e is embedded in the groove 1532f, and the ball 1532e can rotate relative to the floating seat 1532. The limiting groove 1531b is an arc-shaped groove, when the floating seat 1532 slides, the ball 1532e keeps abutting against the inner wall of the limiting groove 1531b and rotates relative to the floating seat 1532, which can reduce the friction between the floating seat 1532 and the fixed seat 1531, and facilitate the sliding of the floating seat 1532.

[0047] With reference to Figure 3 In some embodiments, the locking hook 1533 includes a connecting portion 1533a and a clamping portion 1533b, and the clamping portion 1533b is integrally formed with the connecting portion 1533a. The connecting portion 1533a is detachably connected with the floating seat 1532, and the clamping portion 1533b is connected with the locking tongue 1521. In some embodiments, the clamping portion 1533b is in a cylindrical shape. In other embodiments, the clamping portion 1533b can be in a curved arc shape or a ring shape or other shapes. In other embodiments, the clamping portion 1533b can also be welded or connected by other means with the connecting portion 1533a. The detachable connection between the connecting portion 1533a and the floating seat 1532 facilitates the replacement of the corresponding locking hook 1533 according to different vehicle door locks 152 or vehicle models.

[0048] In some embodiments, the connecting portion 1533a is threadedly connected with the floating seat 1532. For example, the floating seat 1532 is provided with a connecting screw hole 1532g, the axial direction of the connecting screw hole 1532g intersects with the sliding direction of the floating seat 1532, for example, the axial direction of the connecting screw hole 1532g is perpendicular to the sliding direction of the floating seat 1532. The connecting portion 1533a is provided with external threads, and the connecting portion 1533a is threadedly connected with the connecting screw hole 1532g, so that the connecting portion 1533a is detachably connected with the floating seat 1532. In other embodiments, the floating seat 1532 can be provided with a stud, and the connecting portion 1533a can be provided with a threaded hole, and the threaded hole and the stud are threadedly connected, so that the connecting portion 1533a is threadedly connected with the floating seat 1532.

[0049] In other embodiments, the connecting portion 1533a and the floating seat 1532 can also be detachably connected by clamping or by screws or other means or structures.

[0050] In other embodiments, the connecting portion 1533a can be welded or integrally formed with the floating seat 1532, so that the locking hook 1533 and the floating seat 1532 can be stably connected.

[0051] In some embodiments, the locking hook assembly 153 further comprises a locking piece 1535 located at least partially between the fixed seat 1531 and the floating seat 1532, and the locking piece 1535 is capable of fixing the floating seat 1532 at any position within the preset range 1531e that matches the lock tongue 1521. When the vehicle door body 151 (see Figure 1 ) needs to be corrected after deformation, the floating seat 1532 can be fixed by the locking piece 1535, so that the position of the locking hook 1533 remains fixed, and thus the success of the correction of the vehicle door body 151 can be determined by comparing the position of the lock tongue 1521 relative to the locking hook 1533 before and after the correction of the vehicle door body 151. In other embodiments, when the all-terrain vehicle 100 needs to travel on a bumpy road, the floating seat 1532 can be fixed by the locking piece 1535 to fix the locking hook 1533, so that the locking hook 1533 has a limiting effect on the vehicle door body 151 in the up-down direction through the cooperation of the locking hook 1533 and the lock tongue 1521, thereby reducing the risk of collision between the vehicle door body 151 and the vehicle frame 11 caused by the up-down shaking of the vehicle door body 151.

[0052] In some embodiments, the connecting screw hole 1532g is provided through, and the locking piece 1535 comprises a connecting portion 1533a, one end of the connecting portion 1533a away from the clamping portion 1533b is capable of penetrating through the connecting screw hole 1532g and abutting against the fixed seat 1531. After rotating the connecting portion 1533a to make the connecting portion 1533a abut against the bottom wall of the accommodating groove 1531a, the limiting protrusion 1532a and the inner wall of the limiting groove 1531b abut against each other, so that the floating seat 1532 is fixed relative to the fixed seat 1531.
