Description

Technical Field

[0001] This utility model relates to the field of vehicle storage boxes, and in particular to a storage box disassembly and assembly device. Background Technology

[0002] In various vehicles and equipment, the installation and removal mechanism of storage compartments plays a crucial role. It directly affects the convenience and stability of the compartment's use, as well as the overall performance of the equipment. Currently, common locking mechanisms on the market mainly include rubber expansion locking and cam-spring locking. Although these solutions can all achieve the locking function of the storage compartment, they still have the following technical shortcomings:

[0003] 1. The rubber expansion locking mechanism has high assembly complexity, requiring the handle to be removed before installing the cargo box, which increases the operation steps and affects the user experience, especially in scenarios with frequent disassembly and assembly, where efficiency is low.

[0004] 2. The cam-spring locking structure is complex and costly. The cam and spring structure has many parts, resulting in high processing and assembly costs. Furthermore, the spring may experience elastic decay after long-term use, leading to a decrease in locking force.

[0005] 3. At the same time, existing designs cannot be adapted to mounting surfaces of different thicknesses (such as cargo box brackets for different vehicle models), which limits their applicability.

[0006] Therefore, there is an urgent need to develop a quick-release mechanism for the storage box of all-terrain vehicles, which uses a combination of cams and expanding rubber. This design allows for flexible adjustment of the locking thickness, increasing its applicability, and combines the advantages of simple structure and low cost. Utility Model Content

[0007] In view of this, the purpose of this utility model is to provide a quick-release mechanism for the storage box of an all-terrain vehicle and the all-terrain vehicle itself, which adopts a combination of cam and expansion rubber, and the locking thickness of this design can be flexibly adjusted.

[0008] This utility model discloses a quick-assembly and disassembly mechanism for an all-terrain vehicle storage box, comprising a mounting base, a locking assembly, and a clamping block. The mounting base is used for mounting on a shelf and is provided with a locking hole. The locking assembly includes a bolt and an expansion assembly. The expansion assembly is placed inside the locking hole. The clamping block is located above the expansion assembly and is limited upward. The bolt passes through the clamping block and the expansion assembly in sequence and can be driven to move up and down. By moving up and down, the expansion assembly expands and tightens with the locking hole to form a lock or release, thereby causing the clamping block to press the storage box or release it.

[0009] Furthermore, it also includes a locking handle, which is located above the clamping block and is upper limited above the clamping block, and the bolt passes through the locking handle and is lower limited relative to the locking handle.

[0010] Furthermore, the locking handle and the clamping block are engaged by an end face cam pair. By rotating the locking handle, the end face cam pair drives the bolt to move upward, thereby causing the expansion component to expand and tighten with the locking hole to form a lock.

[0011] Furthermore, the expansion assembly includes an elastic expansion sleeve and an expansion cone that cooperates with the elastic expansion sleeve. When the bolt is driven upward, it causes the expansion cone to move upward, causing the elastic expansion sleeve to expand.

[0012] Furthermore, the bolt is subjected to a downward preload.

[0013] Furthermore, the expansion cone is sleeved on the bolt and limited downward by the locking nut, and a spring sleeved on the bolt is provided on the inner circle of the elastic expansion sleeve. The two ends of the spring abut against the expansion cone and the clamping block respectively, thereby applying the preload force to the bolt.

[0014] Furthermore, the inner circle of the elastic expansion sleeve mates with the expansion cone to form a conical surface.

[0015] Furthermore, the clamping block has a clamping part extending laterally on its upper side, which is used to cooperate with the clamped part of the storage box.

[0016] Furthermore, the pressing part is provided with a pressing rod, and the pressed part is a pressing groove.

[0017] An all-terrain vehicle, the all-terrain vehicle being equipped with a quick-release mechanism for an all-terrain vehicle storage box as described in any of the above descriptions.

[0018] The beneficial effects of this utility model are as follows: The quick assembly and disassembly mechanism of the all-terrain vehicle storage box and the all-terrain vehicle of this utility model adopt a combination of cam and expansion rubber, which is conducive to the quick assembly and disassembly of various specifications of cargo boxes of all-terrain vehicles and has good versatility. At the same time, the locking thickness of this design can be flexibly adjusted, which increases the scope of use, and also has the advantages of simple structure and low cost.

[0025] As shown in the figure: The quick-release mechanism for the all-terrain vehicle storage box in this embodiment includes a mounting base, a locking assembly, and a clamping block 3. The mounting base is used to install on the shelf 15 and is provided with a locking hole 9. The locking assembly includes a bolt 2 and an expansion assembly. The expansion assembly is placed in the locking hole 9. The clamping block 3 is located above the expansion assembly and is limited upward. The bolt 2 passes through the clamping block 3 and the expansion assembly in sequence and can be driven to move up and down. The up and down movement causes the expansion assembly to expand and tighten with the locking hole 9 to form a lock or release, thereby causing the clamping block 3 to press the storage box 13 or release it. As shown in the figure, this utility model includes a mounting base, a locking assembly, and a clamping block 3. The mounting base is... The device is fixedly installed on the shelf 15 by bolt 12. The shelf 15 is further installed on the frame. The shelf 15 is also equipped with a shelf cover 14 for placing the storage box 13. The mounting base is provided with a locking hole 9. The locking assembly includes a bolt 2 and an expansion assembly. The expansion assembly is fitted into the locking hole 9. The pressing block 3 is located on the upper part of the expansion assembly and is constrained and restricted to move upward by the locking handle 1 and the bolt 2. The bolt 2 passes through the pressing block 3 and the expansion assembly from top to bottom and can be driven by the locking handle 1 to move up and down along the axis. The up and down movement causes the expansion assembly to expand, and at the same time, it tightens with the locking hole 9 to form a locking or releasing mechanism, thereby pressing the storage box 13 with the pressing block 3 or releasing it.

[0026] In this embodiment, a locking handle 1 is also included. The locking handle 1 is located on the upper part of the clamping block 3 and limits the clamping block 3 upward. The bolt 2 passes through the locking handle 1 and is limited downward relative to the locking handle 1. As shown in the figure, the locking handle 1 is installed on the upper part of the clamping block 3 by the bolt 2 and forms an upward limiting constraint on the clamping block 3. At the same time, the bolt 2 is installed in a countersunk hole with a step on the locking handle 1 and forms a downward limiting constraint on the bolt 2 relative to the locking handle 1 through the step.

[0027] In this embodiment, the locking handle 1 and the clamping block 3 are engaged by an end-face cam pair. By rotating the locking handle 1, the end-face cam pair drives the bolt 2 to move upward, thereby causing the expansion component to expand and tighten with the locking hole 9 to form a lock. As shown in the figure, the locking handle 1 and the clamping block 3 are engaged by an end-face cam pair, and a cam structure is formed on the contact surface. By rotating the locking handle 1, the end-face cam pair drives the bolt 2 to move upward relative to the expansion component in the axial direction, thereby causing the expansion component to expand and tighten with the locking hole 9 to form a lock. In this embodiment, the locking handle 1 adopts a cam structure that can rotate left and right along the axis, and is provided with several cam grooves for locking and limiting rotation, for locking the locking position of the locking handle 1. At the same time, the locking handle 1 can also use a cam structure that moves up and down to drive the bolt 2 to achieve locking, or use a rotating nut or other means to achieve the up and down movement of the bolt 2, which will not be described in detail here.

[0028] In this embodiment, the expansion assembly includes an elastic expansion sleeve 6 and an expansion cone 7 that cooperates with the elastic expansion sleeve 6. When the bolt 2 is driven upward, it causes the expansion cone 7 to move upward, causing the elastic expansion sleeve 6 to expand. As shown in the figure, the locking assembly includes an elastic expansion sleeve 6 and an expansion cone 7 that cooperates with the elastic expansion sleeve 6. The elastic expansion sleeve 6 is made of a material with a set elasticity, such as rubber, and the expansion cone 7 is made of a material with a certain hardness, such as metal. Further details are omitted here. The elastic expansion sleeve 6 and the expansion cone 7 are installed together by a bolt 2 that passes through the locking assembly. When the bolt 2 is driven upward, it causes the expansion cone 7 to move upward and squeeze the elastic expansion sleeve 6. After being squeezed and expanded, the elastic expansion sleeve 6 rubs against the inner wall of the locking hole 9 and achieves locking.

[0029] In this embodiment, the bolt 2 is subjected to a downward preload. As shown in the figure, in order to ensure that the expansion assembly can be separated from the mounting base in the released state or when it is not locked, the bolt 2 is subjected to a downward preload. At the same time, a washer 4 is provided between the expansion assembly and the clamping block 3 to prevent the elastic expansion sleeve 6 from sticking to the clamping block 3.

[0030] In this embodiment, the expansion cone 7 is sleeved on the bolt 2 and is limited downward by the locking nut 8. A spring 5, sleeved on the bolt 2, is located on the inner circle of the elastic expansion sleeve 6. The two ends of the spring 5 abut against the expansion cone 7 and the clamping block 3, respectively, thereby applying the preload force to the bolt 2. As shown in the figure, the expansion cone 7 is located at the end of the bolt 2, and the locking nut 8 forms a downward limiting constraint on the expansion cone 7. At the same time, a spring 5, sleeved on the bolt 2, is located on the inner circle of the elastic expansion sleeve 6. The two ends of the spring 5 abut against the expansion cone 7 and the clamping block 3, respectively. In this embodiment, the two ends of the spring 5 abut against the washer 4 at the lower end of the expansion cone 7 and the clamping block 3, respectively. The spring 5 applies a preload force to the bolt 2 through its elastic force. The spring 5 can also be used to reset the expansion cone 7 after the locking is released.

[0031] In this embodiment, the inner circle of the elastic expansion sleeve 6 and the expansion cone 7 cooperate to form a conical surface; as shown in the figure, the bottom end of the elastic expansion sleeve 6 is a conical surface that conforms to the expansion cone 7, which facilitates expansion under the pressure of the expansion cone 7, thereby achieving the locking of the expansion component and the mounting base.

[0032] In this embodiment, the pressing block 3 has a pressing part extending laterally on its upper side, which is used to cooperate with the pressed part of the storage box 13. As shown in the figure, the pressing block 3 has a pressing part extending laterally on its upper side. The pressing part can be integrally formed on the pressing block, or it can be installed on the upper part of the pressing block 3 in other ways. The pressing part cooperates with the pressed part of the storage box 13, which can realize the quick installation and removal of the storage box 13.

[0033] In this embodiment, the pressing part is provided with a pressing rod 10, and the pressed part is a pressing groove 11; as shown in the figure, the pressing part is provided with a pressing rod 10, and the shape of the pressing rod 10 is adapted to the pressing groove 11 provided at the installation position of the storage box 13.
