Description

TECHNICAL FIELD

[0002] The seat of the existing all-terrain vehicle is usually installed with the seat frame by the cooperation of the latch and the simple cushion lock, and a certain hand unlocking space is left at the tail of the cushion. When the driver needs to unlock the seat, the driver needs to stretch his arm into the hand unlocking space and control the simple cushion lock to separate from the seat, so that the seat is separated from the frame.

[0003] In addition, since the simple cushion lock is usually located below the seat, the seat of the all-terrain vehicle in the prior art is almost invisible when it is unlocked, which causes the driver to need to feel by the palm to identify the unlocking position when unlocking, and the unlocking process of the seat is relatively cumbersome.

[0028] In order to make the personnel in the art better understand the scheme of the present application, the technical scheme in the specific embodiment of the present application will be described clearly and completely below in combination with the drawings in the embodiment of the present application.

[0029] As shown in Figure 1 , the present application provides an all-terrain vehicle 100, which comprises a frame 11, a vehicle body cover 12, a seat assembly 13 and a walking assembly 14. The frame 11 constitutes the basic frame of the all-terrain vehicle 100, the vehicle body cover 12 is installed on the frame 11 and covers at least part of the frame 11, the vehicle body cover 12 is used to protect the components inside the all-terrain vehicle 100, the seat assembly 13 is installed on the frame 11 for the driver to sit on, and one end of the seat assembly 13 is rotatably connected with the frame 11, so that the seat assembly 13 can rotate around the connection end thereof with the frame 11 relative to the frame 11. At least part of the walking assembly 14 is located below the frame 11 to support the all-terrain vehicle 100 and drive the all-terrain vehicle 100 to travel. In order to clearly illustrate the technical scheme of the present application, the upward, downward, leftward, rightward, forward and backward directions as shown in Figure 1 are taken as the upward, downward, leftward, rightward, forward and backward directions of the all-terrain vehicle 100.

[0030] As shown in Figure 2As shown, the all-terrain vehicle 100 further comprises a seat locking device 15, which is installed on the vehicle frame 11 and at least part of the seat locking device 15 is located between the vehicle frame 11 and the seat assembly 13, and the seat locking device 15 is used to lock or unlock the seat assembly 13, so that the seat assembly 13 has the open state and the closed state as shown. Figure 3 and Figure 4 When the seat assembly 13 is connected with the seat locking device 15, the seat assembly 13 is in the closed state; when the seat assembly 13 is separated from the seat locking device 15, the seat assembly 13 is in the open state.

[0031] The seat locking device 15 comprises a locking mechanism 151, a cable mechanism 152 and an operating mechanism 153, the cable mechanism 152 comprises a first end 1521 and a second end 1522 arranged oppositely, wherein the first end 1521 of the cable mechanism 152 is connected with the locking mechanism 151, and the second end 1522 of the cable mechanism 152 is connected with the operating mechanism 153. The pressing operation of the operating mechanism 153 generates an unlocking force, and the unlocking force is transmitted to the locking mechanism 151 through the cable mechanism 152, wherein the locking mechanism 151 comprises an unlocking state and a locking state, and the locking mechanism 151 is in the unlocking state under the action of the unlocking force; when the pressing operation of the operating mechanism 153 is not performed, the locking mechanism 151 is in the locking state.

[0032] As shown, Figure 3 The locking mechanism 151 is fixed on the vehicle frame 11 and located between the seat assembly 13 and the vehicle frame 11. The seat assembly 13 comprises a fixing pin 131, which is installed on the lower side end face of the seat assembly 13 and extends downward of the all-terrain vehicle 100, so that the seat assembly 13 can be clamped with the locking mechanism 151 through the fixing pin 131, so that the seat assembly 13 is in the closed state.

[0033] One end of the seat assembly 13 is rotatably connected with the vehicle frame 11, and one end of the seat assembly 13 is rotatably connected with the vehicle frame 11 through a rotating shaft (not shown in the figure), when the fixing pin 131 is separated from the locking mechanism 151, the seat assembly 13 can rotate relative to the vehicle frame 11 along the circumference of the rotating shaft, so that the seat assembly 13 is in the open state. When the seat assembly 13 is clamped with the locking mechanism 151 through the fixing pin 131, the seat assembly 13 and the vehicle frame 11 remain relatively fixed, at this time the seat assembly 13 is in the closed state.

[0034] As shown, Figure 5As shown, optionally, the frame 11 includes a sheet metal part 111 for connecting the seat assembly 13. The sheet metal part 111 has a through-hole 1111 extending through two opposite surfaces of the sheet metal part 111, allowing at least a portion of the seat assembly 13 to pass through the through-hole 1111. The seat assembly 13 includes a rotating portion 132 passing through the through-hole 1111. When the retaining pin 131 is separated from the locking mechanism 151, the seat assembly 13 can rotate around the rotating portion 132, and the rotating portion 132 is limited by the through-hole 1111. If it is necessary to remove the seat assembly 13 from the frame 11, the rotating portion 132 is removed from the through-hole 1111, thus separating the seat assembly 13 from the frame 11.

[0035] It should be noted that the above are only two preferred embodiments, and this application does not specifically limit the connection method between the frame 11 and the seat assembly 13.

[0036] like Figure 6 As shown, the operating mechanism 153 is mounted on the body panel 12. When the retaining pin 131 engages with the locking mechanism 151, pressing the operating mechanism 153 can unlock the locking mechanism 151, making it possible for the retaining pin 131 to separate from the locking mechanism 151. The operating mechanism 153, mounted on the body panel 12, prevents interference between the operating mechanism 153 and the seat assembly 13, or between the operating mechanism 153 and the frame 11, facilitating pressing operations by the driver and passengers.

[0037] Exemplarily, the all-terrain vehicle 100 includes a fuel tank 16 located in front of the seat assembly 13. The body cover 12 includes a first cover 121 located in front of the seat assembly 13 and covering at least a portion of the fuel tank 16. An operating mechanism 153 is fixed to the first cover 121, and the first cover 121 has openings 1211 extending through its two opposing surfaces. At least a portion of the operating mechanism 153 passes through these openings 1211, and the operating mechanism 153 is at least partially located on the outer side of the first cover 121, wherein the outer side of the first cover 121 represents the side of the first cover 121 facing away from the fuel tank 16. This arrangement facilitates the operation of the operating mechanism 153 by a driver or passenger.

[0038] Optionally, the vehicle body cover 12 further comprises a second cover 122, which is located below the seat assembly 13 and distributed on both sides of the seat assembly 13, and the second cover 122 covers at least part of the frame 11 for protecting the legs of the driver and passenger. As another optional implementation, the operating mechanism 153 can also be fixed to the second cover 122, and the second cover 122 has an opening (not shown in the figure) penetrating through the opposite two surfaces thereof, at least part of the operating mechanism 153 passes through the opening of the second cover 122, and the operating mechanism 153 is at least partially located outside the second cover 122, wherein the outside of the second cover 122 means the side of the second cover 122 facing away from the frame 11.

[0039] Optionally, the walking assembly 14 comprises a rear wheel 141, and the vehicle body cover 12 further comprises a third cover 123, which is located behind the seat assembly 13 and above the rear wheel 141, wherein the third cover 123 is also called a fender. The operating mechanism 153 is fixed to the third cover 123, and the third cover 123 has an opening (not shown in the figure) penetrating through the opposite two surfaces thereof. As another optional implementation, at least part of the operating mechanism 153 passes through the opening of the third cover 123, and the operating mechanism 153 is at least partially located outside the third cover 123, wherein the outside of the third cover 123 means the side of the third cover 123 facing away from the rear wheel 141.

[0040] It should be noted that the above is only for several preferred implementations of the installation position of the operating mechanism 153, and since the cable mechanism 152 has a certain extensibility and flexibility, the operating mechanism 153 can also be installed at other positions away from the seat assembly 13, and the present application does not specifically limit the installation position of the operating mechanism 153 on the premise of facilitating the pressing operation of the operating mechanism 153.

[0041] As another optional implementation, the all-terrain vehicle 100 further comprises a steering device 17 (see Figure 1 ), which is fixedly installed on the frame 11, and the steering device 17 is used to control the driving direction of the all-terrain vehicle 100. In addition to being installed on the vehicle body cover 12, the operating mechanism 153 can also be installed on the steering device 17, thereby facilitating the touch operation of the operating mechanism 153 by the driver and passenger.

[0042] Specifically, the first end 1521 of the cable mechanism 152 is connected with the locking mechanism 151, the cable mechanism 152 passes through the space between the first cover 121 and the fuel tank 16, and extends towards the direction of the steering device 17, and the second end 1522 of the cable mechanism 152 is connected with the operation mechanism 153. The steering device 17 comprises a steering handle 171, and the operation mechanism 153 is fixed to the steering handle 171 so as to accommodate the cable mechanism 152 and a plurality of wire harnesses distributed on the steering handle 171.

[0043] Through the above arrangement, since the operation mechanism 153 is installed at a position convenient for the driver to operate on the vehicle body cover 12, the periphery of the operation mechanism 153 has sufficient unlocking space, so that the operation mechanism 153 and the seat assembly 13 do not interfere with each other, and the shape of the seat assembly 13 does not need to be adjusted, the processing steps of the seat assembly 13 are reduced, and the integrity of the seat assembly 13 is ensured. In addition, the force acting on the operation mechanism 153 is transmitted to the locking mechanism 151 through the cable mechanism 152, and the driver can control the seat cushion locking device 15 to switch from the locked state to the unlocked state through the touch operation on the operation mechanism 153, so that the unlocking of the seat assembly 13 is relatively simple.

[0044] As shown in Figure 7 As an implementation manner, at least one rubber pad 133 is further arranged between the seat assembly 13 and the frame 11, the rubber pad 133 is fixed to the lower side end face of the seat assembly 13, the rubber pad 133 is located between the seat assembly 13 and the frame 11 and extends from the seat assembly 13 to the frame 11, and when the seat assembly 13 is in the closed state, the rubber pad 133 abuts against the side end face of the frame 11 facing the seat assembly 13.

[0045] Alternatively, the rubber pad 133 is fixed to the frame 11 and extends from the frame 11 to the seat assembly 13, and when the seat assembly 13 is in the closed state, the rubber pad 133 abuts against the side end face of the seat assembly 13 facing the frame 11.

[0046] When the seat assembly 13 is in the closed state and the seat cushion locking device 15 is in the locked state, the upper and lower sides of the rubber pad 133 abut against the seat assembly 13 and the frame 11 respectively, so that the rubber pad 133 is compressed and exerts a reverse force on the seat assembly 13 or the frame 11. When the seat cushion locking device 15 is in the unlocked state, the rubber pad 133 can extend in the direction opposite to the compression direction and push the seat assembly 13 to move relative to the frame 11, thereby facilitating the separation of the locking mechanism 151 and the fixed pin 131.

[0047] In addition, the rubber pad 133 can also avoid the direct contact between the lower side end face of the seat assembly 13 and the locking mechanism 151, so as to reduce the wear therebetween.

[0048] As shown in Figure 8 and Figure 9 illustrated, as an implementation manner, the locking mechanism 151 includes a base 1511, a rotating pin 1512 and a locking hook 1513. The base 1511 is fixed on the frame 11 and constitutes a main frame of the locking mechanism 151. The rotating pin 1512 is fixedly installed on the base 1511, wherein the rotating pin 1512 is substantially cylindrical. The locking hook 1513 is installed on the rotating pin 1512, and the locking hook 1513 and the rotating pin 1512 are in clearance fit, so that the locking hook 1513 can rotate relative to the rotating pin 1512 along the circumference of the rotating pin 1512. The locking hook 1513 is fixedly connected with the first end 1521 of the cable mechanism 152, and then the cable mechanism 152 can drive the locking hook 1513 to rotate along the circumference of the rotating pin 1512, so as to make the locking hook 1513 engage with or separate from the fixed pin 131. When the seat cushion locking device 15 is in the locked state, the locking hook 1513 can engage with the fixed pin 131. When the pressing operation is performed on the operating mechanism 153, the operating mechanism 153 can drive the locking hook 1513 to rotate through the cable mechanism 152, so as to make the locking hook 1513 separate from the fixed pin 131, and then control the seat cushion locking device 15 to be in the unlocked state.

[0049] Specifically, the locking hook 1513 includes oppositely arranged head 1513a and tail 1513b, and the rotating pin 1512 is located between the head 1513a and the tail 1513b. The locking hook 1513 is clamped with the first end 1521 of the cable mechanism 152 through the tail 1513b. The fixed pin 131 is provided with a groove 1311. When the seat cushion locking device 15 is in the locked state, the locking hook 1513 can engage with the groove 1311 of the fixed pin 131 through the head 1513a. When the pressing operation is performed on the operating mechanism 153, the cable mechanism 152 can drive the tail 1513b of the locking hook 1513 to rotate, so as to make the head 1513a separate from the groove 1311 of the fixed pin 131.

[0050] In the above arrangement, the force applied on the operating mechanism 153 is transmitted to the locking hook 1513 through the cable mechanism 152, so that the locking hook 1513 rotates and the seat cushion locking device 15 is in the unlocked state. In this process, the loss of the force is small, and the friction during the rotation of the locking hook 1513 is small. While ensuring that the locked seat assembly 13 has high stability, a small force is applied on the operating mechanism 153 to unlock the seat assembly 13, so that the unlocking of the seat assembly 13 is simple.

[0051] As shown in Figure 8As shown, as an implementation manner, the base 1511 comprises a first limiting slot 1511a for accommodating the fixing pin 131 and a second limiting slot 1511b for accommodating the lock hook 1513. The first limiting slot 1511a and the second limiting slot 1511b are provided with an opening 1511c therebetween, so that the space of the first limiting slot 1511a and the space of the second limiting slot 1511b can be communicated through the opening 1511c.

[0052] Specifically, at least part of the head 1513a is located in the opening 1511c. Taking the working condition that the fixing pin 131 is located in the first limiting slot 1511a as an example, when the seat assembly 13 is in the closed state, the fixing pin 131 is located in the first limiting slot 1511a, and at this time, the groove 1311 of the fixing pin 131 is located in the opening 1511c, so that the head 1513a of the lock hook 1513 can be engaged with the groove 1311 on the fixing pin 131. When the cushion locking device 15 is in the unlocked state, the head 1513a of the lock hook 1513 is located in the second limiting slot 1511b, and at this time, the head 1513a of the lock hook 1513 is separated from the groove 1311 of the fixing pin 131, so that the fixing pin 131 is separated from the locking mechanism 151.

[0053] As shown, Figure 10As shown, as an implementation manner, a projection plane 101 perpendicular to the axis of the rotating pin 1512 is defined, a projection of the axis of the rotating pin 1512 on the projection plane 101 along the axis of the rotating pin 1512 is defined as a first projection point P1, a projection of the tail end 1513b of the locking hook 1513 farthest from the rotating pin 1512 on the projection plane 101 along the axis of the rotating pin 1512 is defined as a second projection point P2, when the seat locking device 15 is in the locked state, a line connecting the first projection point P1 and the second projection point P2 is defined as a first reference line L1, when the seat locking device 15 is in the unlocked state, a line connecting the first projection point P1 and the second projection point P2 is defined as a second reference line L2, wherein an included angle a between the first reference line L1 and the second reference line L2 is greater than or equal to 25° and less than or equal to 40°. Further, the included angle a between the first reference line L1 and the second reference line L2 is greater than or equal to 30° and less than or equal to 35°. More preferably, the included angle a between the first reference line L1 and the second reference line L2 is equal to 33°. It should be noted that when the included angle a between the first reference line L1 and the second reference line L2 is too small, the engagement depth between the head 1513a of the locking hook 1513 and the groove 1311 on the fixed pin 131 is shallow, that is, the connection strength between the locking hook 1513 and the fixed pin 131 is poor. Since the all-terrain vehicle 100 usually travels on relatively complex road conditions, the all-terrain vehicle 100 will appear to be greatly up and down, and if the connection strength between the locking hook 1513 and the fixed pin 131 is poor, the fixed pin 131 will be easily separated from the locking mechanism 151, thereby causing the connection stability of the locking mechanism 151 to be poor. When the included angle a between the first reference line L1 and the second reference line L2 is too large, the engagement depth between the head 1513a of the locking hook 1513 and the groove 1311 on the fixed pin 131 is too deep, and when the seat locking device 15 is switched from the locked state to the unlocked state, a greater force needs to be applied to increase the stroke of the locking hook 1513 so that the head 1513a is completely separated from the groove 1311 on the fixed pin 131, which undoubtedly increases the operation difficulty and affects the reliability of the seat locking device 15. Through the above setting, the connection stability of the locking mechanism 151 is improved, and the reliability of the seat locking device 15 is ensured. Understandably, the "axis of the rotating pin 1512" described in the present application refers to the rotating axis of the locking hook 1513 arranged on the rotating pin 1512 and rotating around the rotating pin 1512.

[0054] As Figure 11As shown, as an implementation manner, the operating mechanism 153 comprises a first mounting member 1531, a second mounting member 1532 and a limiting member 1533. The first mounting member 1531 is fixedly connected with the vehicle body cover 12 or the steering device 17. Taking the case that the operating mechanism 153 is mounted on the first cover 121 as an example, the first mounting member 1531 is mounted on the side of the first cover 121 facing the fuel tank 16. At least part of the second mounting member 1532 is located in the space surrounded by the first mounting member 1531, and the end of the second mounting member 1532 away from the first mounting member 1531 penetrates the opening 1211 of the first cover 121 and extends to the outside of the first cover 121, so that the driver can apply a pressing operation to the first mounting member 1531. Wherein, the first mounting member 1531 can move relative to the second mounting member 1532 along the extension direction of the second mounting member 1532.

[0055] Specifically, the first mounting member 1531 surrounds a first mounting cavity 1531a in a cylindrical shape, and at least part of the second mounting member 1532 is located in the first mounting cavity 1531a. The second mounting member 1532 can move relative to the first mounting member 1531 in the first mounting cavity 1531a along the extension direction of the first mounting cavity 1531a. The second mounting member 1532 surrounds a second mounting cavity 1532a, and the second mounting cavity 1532a communicates with the first mounting cavity 1531a in the extension direction of the first mounting cavity 1531a, so that the cable mechanism 152 can pass through the first mounting cavity 1531a and the second mounting cavity 1532a in sequence.

[0056] The limiting member 1533 is fixed to the first mounting member 1531, and the first mounting member 1531 comprises a side wall 1531b surrounding the first mounting cavity 1531a. The limiting member 1533 is mounted on the side wall 1531b and extends towards the second mounting cavity 1532a, so that the cable mechanism 152 passing through the second mounting cavity 1532a is fixed to the limiting member 1533.

[0057] Specifically, the cable mechanism 152 includes a sleeve 1523 and a pull rope 1524. The pull rope 1524 passes through the sleeve 1523. Both the sleeve 1523 and the pull rope 1524 are made of materials that are incompressible or difficult to compress in their extension direction, such as metal. The sleeve 1523 includes a first connecting portion 1523a and a second connecting portion 1523b arranged opposite to each other. The two ends of the pull rope 1524 are respectively provided with a first connector 1524a and a second connector 1524b. The first connector 1524a is close to the first connecting portion 1523a, and the second connector 1524b is close to the second connecting portion 1523b. The second connector 1524b is located in the second mounting cavity 1532a and abuts against the limiting member 1533 in the direction from the second mounting member 1532 to the first mounting member 1531a. The end of the second mounting member 1532 near the first mounting cavity 1531a is also connected to the second connecting portion 1523b. The first connecting part 1523a abuts against the base 1511, and the first joint 1524a of the pull rope 1524 engages with the tail 1513b of the locking hook 1513.

[0058] For example, when the second mounting member 1532 is pressed, the second mounting member 1532 drives the second connecting portion 1523b to move away from the second connector 1524b, thereby compressing the space of the first mounting cavity 1531a. Since the limiting member 1533 is fixedly connected to the first mounting member 1531, and the second connector 1524b abuts against the limiting member 1533 in the direction from the second mounting member 1532 to the first mounting member 1531, the distance between the second connecting portion 1523b and the second connector 1524b increases. Since both the sleeve 1523 and the pull rope 1524 are incompressible or difficult to compress, the lengths of the sleeve 1523 and the pull rope 1524 remain unchanged. Therefore, the increase in the distance between the second connecting portion 1523b and the second connector 1524b leads to a decrease in the distance between the first connecting portion 1523a and the first connector 1524a. Since the first connecting part 1523a abuts against the base 1511, and the first connector 1524a of the pull rope 1524 engages with the tail 1513b of the locking hook 1513, the reduced distance between the first connecting part 1523a and the first connector 1524a causes the first connector 1524a to drive the tail 1513b of the locking hook 1513 to rotate, so that the head 1513a of the locking hook 1513 separates from the fixing pin 131, that is, the locking mechanism 151 separates from the fixing pin 131, thereby realizing the seat cushion locking device 15 switching from the locked state to the unlocked state.

[0059] like Figure 11 As shown, in one implementation, the seat locking device 15 includes a reset mechanism 154, which is used to drive the locking mechanism 151 into a locked state when the operating mechanism 153 loses the unlocking force applied to it.

[0060] Specifically, the reset mechanism 154 includes a first elastic member 1541 and a second elastic member 1542, which are respectively located at the first end 1521 and the second end 1522 of the cable mechanism 152.

[0061] Specifically, the first elastic member 1541 is installed on the base 1511 and sleeved on the pull rope 1524, one end of the first elastic member 1541 abuts against the base 1511, and the other end of the first elastic member 1541 abuts against the tail 1513b of the lock hook 1513. The second elastic member 1542 is located in the first mounting cavity 1531a and sleeved on the second connecting portion 1523b. One end of the first elastic member 1541 abuts against the first mounting member 1531, and the other end of the second elastic member 1542 abuts against the second mounting member 1532.

[0062] When the control cushion locking device 15 is in the unlocked state, i.e., the second mounting member 1532 is touched, the second mounting member 1532 can move in the first mounting cavity 1531a and compress the second elastic member 1542. In addition, when the second mounting member 1532 is touched, the distance between the first connecting portion 1523a and the first joint 1524a is also reduced, thereby compressing the first elastic member 1541. When the control cushion locking device 15 is in the locked state, i.e., the second mounting member 1532 is stopped being pressed, the elastic potential energy accumulated by the first elastic member 1541 forces the lock hook 1513 to reset, and the elastic potential energy accumulated by the second elastic member 1542 forces the second mounting member 1532 to reset. In addition, when the control cushion locking device 15 is in the locked state, the lock hook 1513 is pushed by the first elastic member 1541 to be clamped with the fixed pin 131, thereby improving the connection strength between the lock hook 1513 and the fixed pin 131. Through the above setting, the driver can control the seat assembly 13 to be unlocked, and at the same time, the connection strength between the lock hook 1513 and the fixed pin 131 can be improved.

[0063] As Figure 11As shown, as an implementation manner, the second mounting member 1532 comprises an operation portion 1532a and a transmission portion 1532b, the operation portion 1532a is fixedly connected with the transmission portion 1532b, the operation portion 1532a is located at one end of the transmission portion 1532b which is away from the first mounting member 1531, and at least part of the operation portion 1532a passes through the opening 1211 on the vehicle body covering member 12 and extends to the outside of the vehicle body covering member 12, so as to be pressed by the driver. At least part of the transmission portion 1532b is located in the first mounting cavity 1531a, and the transmission portion 1532b surrounds the second mounting cavity 1532a, and one end of the transmission portion 1532b which is away from the operation portion 1532a is connected with the second connecting portion 1523b. When the operation portion 1532a is touched, the transmission portion 1532b can move in the first mounting cavity 1531a along the extension direction of the first mounting cavity 1531a, so as to drive the second connecting portion 1523b to move, wherein the inner contour of the opening 1211 is basically consistent with the outer contour of the operation portion 1532a.

[0064] It should be understood that, for those skilled in the art, improvements or changes can be made according to the above description, and all these improvements and changes shall belong to the protection scope of the claims attached to this application.
