Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an all-terrain vehicle and a method for disassembling and assembling its door components. Background Technology

[0002] All-terrain vehicles (ATVs) are vehicles capable of traveling on all terrains, featuring a high chassis, suspension with superior shock absorption, tires with good traction, and powerful engines. Compared to ordinary vehicles, ATVs can operate in extremely harsh environments, including but not limited to beaches, mountains, forests, and swamps, and are widely used in farms and recreational areas.

[0003] Among them, practical all-terrain vehicles use enclosed cabs, which require the door components to be disassembled and reinstalled for routine maintenance and troubleshooting. The existing door and frame components of practical all-terrain vehicles have relatively complex connection structures, making the installation and disassembly of the door components difficult. Furthermore, when the door components are disassembled and reinstalled, many parts need to be reassembled and the installation parameters adjusted, further increasing the difficulty of installing and disassembling the door components. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a method for disassembling and assembling an all-terrain vehicle and its door components.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] An all-terrain vehicle includes: a frame assembly; a power assembly, at least partially disposed on the frame assembly; a running gear assembly, at least partially disposed on the frame assembly; and a body panel, including door assemblies. The all-terrain vehicle further includes an assembly for connecting the door assembly and the frame assembly. The assembly includes a first fixing member and a second fixing member. The second fixing member includes a fixing portion and a rotating portion. The first fixing member includes a connecting portion connected to the second fixing member and capable of forming a fixed connection with the fixing portion of the second fixing member. The assembly includes a first state and a second state. When the assembly is in the first state, the first fixing member and the second fixing member are separated from each other. When the assembly is in the second state, the first fixing member and the fixing portion are fastened together, and the first fixing member and the second fixing member rotate relative to each other via the rotating portion.

[0007] Furthermore, the second fixing member is provided with a first mounting hole, and the rotating part is at least partially disposed in the first mounting hole.

[0008] Furthermore, the rotating part and the second fixed part are configured to be non-detachably connected, and a bushing is provided between the rotating part and the second fixed part. The bushing is at least partially disposed in the first mounting hole, and the range of the frictional torque between the second fixed part and the rotating part is set to be greater than or equal to 0.2 N·m and less than or equal to 1.2 N·m.

[0009] Furthermore, the rotating part and the second fixed part are configured to be rotatably connected, and a bushing is provided between the rotating part and the second fixed part. The bushing is at least partially disposed in the first mounting hole, and the range of the frictional torque between the second fixed part and the connecting part is set to be greater than or equal to 0.2 N·m and less than or equal to 1.2 N·m.

[0010] Furthermore, the first fastener is provided with a second mounting hole, and when the assembly is in the second state, the fastener is at least partially disposed in the second mounting hole.

[0011] Furthermore, the second fastener is also provided with a third mounting hole, and the assembly assembly also includes a fastener. When the assembly assembly is in the second state, the fastener is at least partially disposed in the third mounting hole. The fastener and the third mounting hole are bolted together, and the fastener abuts against the fixing part through the third mounting hole to restrict the relative movement between the fixing part and the first fastener.

[0012] Furthermore, the door assembly includes a disassembled state and an assembled state. When the door assembly and the frame assembly are in the disassembled state, the assembled assembly is in the first state. When the door assembly and the frame assembly are in the assembled state, the assembled assembly is in the second state.

[0013] Furthermore, the second fastener is provided with a third limiting structure. The second fastener includes a first limit position and a second limit position. When the door assembly is in the closed state, the second fastener is in the first limit position; when the third limiting structure abuts against the first fastener, the second fastener is in the second limit position.

[0014] Furthermore, when the fastener is in the first extreme position, the contact surface between the second fastener and the door assembly extends substantially along the first plane; when the fastener is in the second extreme position, the contact surface between the second fastener and the door assembly extends substantially along the second plane, and the included angle between the first plane and the second plane is set to be greater than or equal to 0° and less than or equal to 76°.

[0015] A method for assembling and disassembling a door assembly, applicable to any of the above-mentioned all-terrain vehicles, includes an assembly assembly for installing the door assembly onto the all-terrain vehicle, the assembly assembly including a first fixing member and a second fixing member, the second fixing member including a rotating part and a fixing part; the all-terrain vehicle includes a frame assembly, the first fixing member including a connecting part, the connecting part including a fastener; characterized in that the method for assembling the door assembly includes:

[0016] S1: Securely connect the first fastener to the frame assembly and the second fastener to the door assembly;

[0017] S2: Connect the fixing part with the connecting part;

[0018] S3: Set the fastener to mate with the connection part.

[0019] The all-terrain vehicle provided in this application features a detachable connection between the first fastener and the connector, facilitating the installation and removal of the door assembly and improving its convenience and flexibility. Furthermore, the riveting of the second fastener and connector, along with the placement of the bushing and gasket at the connection between the connector and the fourth mounting hole, eliminates the need to reinstall the bushing and gasket or readjust the installation parameters of the door assembly during installation. This simplifies the installation process and further enhances the convenience, flexibility, and practicality of the door assembly installation.

[0020] The method for disassembling and assembling the door assembly of the all-terrain vehicle provided in this application allows the door assembly to be changed from an assembled state to a disassembled state by removing it from the first fixing member using the second fixing member, and the door assembly can be changed from a disassembled state to an assembled state by fixing the first fixing member and the connecting member with fasteners, making the installation and disassembly steps of the door assembly simple and quick.

[0031] To enable those skilled in the art to better understand the solutions of this application, the technical solutions in specific embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.

[0032] like Figure 1 and Figure 2 As shown, an all-terrain vehicle 100 includes a frame assembly 11, a power assembly (not shown), a running gear assembly 12, and a body panel 13. The body panel 13 includes a door assembly 131. The frame assembly 11 supports the door assembly 131, the running gear assembly 12, and the body panel 13. The power assembly is at least partially mounted on the frame assembly 11. The door assembly 131 is at least partially mounted on the frame assembly 11 and can improve the comfort and safety of the all-terrain vehicle 100. Specifically, the door assembly 131 and the frame assembly 11 are rotatably connected. The door assembly 131 includes an assembled state and a disassembled state. When the door assembly 131 is connected to the frame assembly 11, it is in the assembled state; when the door assembly 131 is not connected to the frame assembly 11, it is in the disassembled state. The running gear assembly 12 is at least partially mounted on the frame assembly 11 and is used to drive the all-terrain vehicle 100. The body panel 13 is at least partially disposed on the frame assembly 11 and is used to cover the internal parts of the all-terrain vehicle 100.

[0033] like Figure 2 and Figure 3As shown, in one embodiment, the all-terrain vehicle 100 also includes an assembly assembly 14. The assembly assembly 14 is at least partially disposed between the door assembly 131 and the frame assembly 11, with the door assembly 131 connected to the frame assembly 11 via the assembly assembly 14. Specifically, the assembly assembly 14 and the door assembly 131 are fixedly connected, and further, the assembly assembly 14 is fixedly connected to the frame assembly 11 via fasteners. Specifically, the frame assembly 11 is provided with a first mounting hole 111, through which the assembly assembly 14 is connected to the frame assembly 11. Preferably, the first mounting hole 111 is a slotted hole, which can absorb assembly tolerances between the assembly assembly 14 and the frame assembly 11, thereby improving the convenience and flexibility of connecting the door assembly 131 and the frame assembly 11. It is understood that the frame assembly 11 and the assembly assembly 14 can also be integrally formed or fastened together by other means; and the assembly assembly 14 can be connected to the frame assembly 11 or to the body panel 13.

[0034] like Figures 3 to 6 As shown, in one embodiment, the assembly assembly 14 includes a first fixing member 141 and a second fixing member 142. The first fixing member 141 can be connected to the frame assembly 11, and the second fixing member 142 can be connected to the door assembly 131. Alternatively, the first fixing member 141 can be connected to the door assembly 131, and the second fixing member 142 can be connected to the frame assembly 11. The second fixing member 142 is rotatably connected to the first fixing member 141. With the above configuration, the door assembly 131 can be mounted on the frame assembly 11. To clearly illustrate the technical solution of this application, the following are also defined: Figure 5 The front, rear, left, right, top, and bottom sides shown are the front, rear, left, right, top, and bottom directions of the assembly component 14 in this application.

[0035] like Figures 4 to 10As shown, in one embodiment, the second fixing member 142 includes a fixing part 1421 and a rotating part 1422. The rotating part 1422 is disposed on the second fixing member 142 and includes a first part 1422a and a second part 1422b. The first part 1422a is configured to rotate relative to the second part 1422b. The first part 1422a can be fastened to the second fixing member 142 or integrally formed. The second part 1422b can be integrally formed with the fixing part 1421 or fixedly connected. That is, the fixing part 1421 is connected to the second fixing member 142 through the rotating part 1422 and can rotate relative to the first part 1422a. The first fixing member 141 includes a connecting part 1411, which is fixedly connected to the second fixing member 142 through the fixing part 1421. Assembly assembly 14 also includes a first state and a second state. When assembly assembly 14 is in the first state, the first fixing member 141 and the second fixing member 142 are separated from each other. When assembly assembly 14 is in the second state, the first fixing member 141 and the fixing part 1421 are fastened together, and the first fixing member 141 and the second fixing member 142 rotate relative to each other through the rotating part 1422. It can be understood that when the door assembly 131 is in the disassembled state, assembly assembly 14 is in the first state; when the door assembly 131 is in the assembled state, assembly assembly 14 is in the second state. The detachable connection of the first fixing member 141 and the second fixing member 142 facilitates the switching of assembly assembly 14 between the first state and the second state, thereby facilitating the switching of door assembly 131 between the assembled state and the disassembled state, and improving the convenience and flexibility of installing and disassembling door assembly 131.

[0036] Specifically, the connecting portion 1411 is provided with a second mounting hole 1411a and a third mounting hole 1411b, which are connected. The fixing portion 1421 is at least partially disposed within the second mounting hole 1411a, thereby achieving radial limiting of the fixing portion 1421. Further, the assembly assembly 14 also includes a fastener 143, which is at least partially disposed within the third mounting hole 1411b. As one possible implementation, the axis of the second mounting hole 1411a and the axis of the third mounting hole 1411b are set perpendicular to each other. After passing through the third mounting hole 1411b, the fastener 143 abuts against the fixing portion 1421 and applies a preload to the fixing portion 1421. The third mounting hole 1411b can be a threaded hole, and the fastener 143 can be a fastening bolt. The fastener 143 is screwed into the third mounting hole 1411b and applies a preload to the fixing part 1421, thereby limiting the axial and circumferential movement of the fixing part 1421. Through the above arrangement, the fixing part 1421 is fixedly connected to the first fixing member 141 by the fastener 143. It can be understood that when the fastener 143 applies a preload to the fixing part 1421 through the third mounting hole 1411b, the assembly assembly 14 is in the second state; when the fastener 143 does not apply a preload to the fixing part 1421, the assembly assembly 14 is in the first state. By screwing the fastener 143 into or out of the third mounting hole 1411b, it is easy to switch the assembly assembly 14 between the first and second states, and it is also easy to switch the door assembly 131 between the assembled state and the disassembled state, improving the convenience and flexibility of installing and disassembling the door assembly 131.

[0037] Furthermore, a first positioning structure 1421a is provided on the fixing part 1421, and a second positioning structure 1431 is provided on the fastener 143. When the assembly assembly 14 is in the second state, the second positioning structure 1431 abuts against and compresses the first positioning structure 1421a, causing the first positioning structure 1421a to undergo elastic deformation, thereby achieving axial and circumferential positioning of the fixing part 1421. Furthermore, to make the connection between the first positioning structure 1421a and the second positioning structure 1431 tighter, a pattern is also provided on the first positioning structure 1421a, thereby increasing the friction between them. This arrangement improves the fit between the first positioning structure 1421a and the second positioning structure 1431, thereby increasing the connection strength between the fixing part 1421 and the fastener 143 and improving the reliability of the connection between the fixing part 1421 and the first fixing member 141. Furthermore, a gripping portion 1432 is provided at one end of the fastener 143 away from the second positioning structure 1431. When the assembly assembly 14 is in the second state, the gripping portion 1432 is at least partially provided outside the third mounting hole 1411b. The gripping portion 1432 is provided with a pattern to increase friction. The driver or passenger can operate the gripping portion 1432 by hand or with a tool, thereby achieving the fixation of the first fixing member 141 and the second fixing member 142.

[0038] In one embodiment, the rotating part 1422 includes a fourth mounting hole 1422c and a limiting part 1422d. The fourth mounting hole 1422c is disposed on the second fixing member 142, and the limiting part 1422d at least partially passes through the fourth mounting hole 1422c. The fourth mounting hole 1422c can restrict the radial displacement freedom of the limiting part 1422d. The limiting part 1422d forms a non-detachable connection with the second fixing member 142 through the fourth mounting hole 1422c. Specifically, the rotating part 1422 also includes a first limiting structure 1422e and a second limiting structure 1422f. Along the vertical direction of the assembly 14, after the limiting part 1422d passes through the fourth mounting hole 1422c, the upper end of the limiting part 1422d is riveted to form the first limiting structure 1422e, and the second limiting structure 1422b is disposed at the lower end of the fourth mounting hole 1422c. When the assembly assembly 14 is in the first state, the second fixing member 142 at the upper end of the fourth mounting hole 1422c abuts against the first limiting structure 1422e, and the second fixing member 142 at the lower end of the fourth mounting hole 1422c abuts against the second limiting structure 1422f. In this embodiment, the diameter of the first limiting structure 1422e is smaller than the diameter of the fourth mounting hole 1422c, and a gasket 144 is provided between the first limiting structure 1422e and the second fixing member 142. The first limiting structure 1422e, the second limiting structure 1422f, and the gasket 144 cooperate to restrict the axial degree of freedom of the limiting part 1422d. Understandably, if the diameter of the first limiting structure 1422e is larger than the diameter of the fourth mounting hole 1422c, the shim 144 may not be provided between the first limiting structure 1422e and the fourth mounting hole 1422c. The first limiting structure 1422e and the second limiting structure 1422f cooperate to restrict the degree of freedom of the limiting part 1422d in the up and down directions. A bushing 145 is provided between the fourth mounting hole 1422c and the limiting part 1422d. Preferably, along the vertical direction of the assembly 14, the upper end of the bushing 145 extends to the contact point between the upper end of the fourth mounting hole 1422c and the gasket 144, that is, the first limiting structure 1422e abuts against the upper end of the fourth mounting hole 1422c through the gasket 144 and the bushing 145; the lower end of the bushing 145 extends to the contact point between the lower end of the fourth mounting hole 1422c and the second limiting structure 1422f, that is, the second limiting structure 1422f abuts against the lower end of the fourth mounting hole 1422c through the bushing 145. The bushing 145 can buffer the vibration between the fourth mounting hole 1422c and the limiting part 1422d, prevent the connection between the second fixing part 142 and the rotating part 1422 from loosening, and improve the vibration resistance and reliability of the assembly 14; in addition, the bushing 145 can reduce the wear between the fourth mounting hole 1422c and the limiting part 1422d, saving maintenance costs; at the same time, the bushing 145 can increase the coefficient of friction between the limiting part 1422d and the fourth mounting hole 1422c, improving the stability of the door assembly 131 when opening and closing.In this embodiment, the frictional torque range between the limiting part 1422d and the fourth mounting hole 1422c is set to be greater than or equal to 0.2 N·m and less than or equal to 1.2 N·m. It is understood that setting the frictional torque range between the limiting part 1422d and the fourth mounting hole 1422c to be greater than or equal to 0.2 N·m and less than or equal to 1.2 N·m is only one embodiment of this application. This range can be adjusted according to the operating conditions of the all-terrain vehicle 100. The frictional torque range between the limiting part 1422d and the fourth mounting hole 1422c can also be set to be greater than or equal to 0 N·m and less than or equal to 2 N·m, or the frictional torque range between the limiting part 1422d and the fourth mounting hole 1422c can also be set to be greater than or equal to 0.1 N·m and less than or equal to 1.6 N·m. With the above configuration, when the door assembly 131 switches between the first state and the second state, it is not necessary to reinstall the bushing 145 and the gasket 144, nor is it necessary to readjust the installation parameters of the limiting part 1422d and the fourth mounting hole 1422c. At the same time, the connection strength between the second fixing part 142 and the rotating part 1422 is guaranteed, which improves the convenience and flexibility of the door assembly 131 in switching between the first state and the second state.

[0039] like Figures 7 to 9 As shown, in one embodiment, the second fastener 142 includes a first limit position and a second limit position. (As illustrated...) Figure 7 and Figure 9 As shown in the solid line portion of the second fastener 142, when the door assembly 131 is closed, the second fastener 142 is in the first extreme position. Figure 8 and Figure 9 As shown in the dashed section, the second fixing member 142 is provided with a third limiting structure 1423. When the third limiting structure 1423 abuts against the first fixing member 141, the door assembly 131 is opened to its maximum angle, and the second fixing member 142 is in the second extreme position. When the second fixing member 142 is in the first extreme position, the contact surface between the second fixing member 142 and the door assembly 131 extends substantially along plane 101; when the second fixing member 142 is in the second extreme position, the contact surface between the second fixing member 142 and the door assembly 131 extends substantially along plane 102. The included angle α between plane 101 and plane 102 is set to be greater than or equal to 0° and less than or equal to 76°. It is understood that setting the range of the included angle α between plane 101 and plane 102 to be greater than or equal to 0° and less than or equal to 76° is only one embodiment of the application. This range can be adjusted according to the size and type of all-terrain vehicle 100. In this embodiment, the range of the included angle α between plane 101 and plane 102 can also be set to be greater than or equal to 0° and less than or equal to 82°, or the range of the included angle α between the first direction and the second direction can also be set to be greater than or equal to 0° and less than or equal to 70°, etc.

[0040] In this application, the first fixing member 141 and the fixing part 1421 are detachably connected by the fastener 143, which facilitates the switching between the assembled and disassembled states of the door assembly 131, improving the convenience and flexibility of installing and disassembling the door assembly 131. Simultaneously, by providing a first positioning structure 1421a on the fixing part 1421 and a second positioning structure 1431 on the fastener 143, the fit between the fixing part 1421 and the fastener 143 is improved, as is the connection strength, thereby enhancing the reliability of the connection between the second fixing member 142 and the first fixing member 141. By providing a bushing 145 in the fourth mounting hole 1422e, vibration between the second fixing member 142 and the rotating part 1422 can be buffered, and loosening of the connection between the second fixing member 142 and the rotating part 1422 can be prevented, improving the vibration resistance and reliability of the assembly 14. The arrangement of the limiting part 1422f being riveted and connected to the second fastener 142 via the gasket 144 makes it possible to install and remove the door assembly 131 without reinstalling the bushing 145 or readjusting the installation parameters between the limiting part 1422f and the fourth mounting hole 1422e, thus improving the convenience of installing and removing the door assembly 131.

[0041] This application also provides a method for assembling and disassembling a door assembly 131, including an assembly assembly 14 for installing the door assembly 131 onto an all-terrain vehicle 100. The assembly assembly 14 includes a first fixing member 141 and a second fixing member 142. The second fixing member 142 includes a rotating part 1422 and a fixing part 1421. The all-terrain vehicle 100 includes a frame assembly 11. The first fixing member 141 includes a connecting part 1411, and a fastener 143 is provided in the connecting part 1411. The method for assembling the door assembly 131 includes:

[0042] S1: The first fastener 141 is fixedly connected to the frame assembly 11, and the second fastener 142 is fixedly connected to the door assembly 131;

[0043] S2: Connect the fixing part 1421 to the connecting part 1411;

[0044] S3: Set the fastener 143 to mate with the connector 1411.

[0045] The disassembly method for door assembly 131 includes:

[0046] S1: Set the fastener 143 to be separated from the connecting part 1411;

[0047] S2: Separate the fixing part 1421 from the connecting part 1411;

[0048] S3: Remove the first fastener 141 from the frame assembly 11 and remove the second fastener 142 from the door assembly 11.

[0049] As another implementation, the assembly method of the door assembly 131 includes:

[0050] S1: The first fastener 141 is fixedly connected to the door assembly 131, and the second fastener 142 is fixedly connected to the frame assembly 11;

[0051] S2: Connect the fixing part 1421 to the connecting part 1411;

[0052] S3: Set the fastener 143 to mate with the connector 1411.

[0053] The disassembly method for door assembly 131 includes:

[0054] S1: Set the fastener 143 to be separated from the connecting part 1411;

[0055] S2: Separate the fixing part 1421 from the connecting part 1411;

[0056] S3: Remove the first fastener 141 from the door assembly 131 and remove the second fastener 142 from the frame assembly 11.

[0057] In this application, the door assembly 131 can be changed from an assembled state to a disassembled state by separating the second fastener 142 from the first fastener 141, and the door assembly 131 can be changed from a disassembled state to an assembled state by fixing the first fastener 141 and the fixing part 1421 with fasteners 143, making the installation and disassembly steps of the door assembly 131 simple and quick.
