Description

Technical Field

[0001] This utility model relates to the field of automotive accessory technology, and in particular to a linkage locking structure between a spare tire cover folding table and an insulated box. Background Technology

[0002] With the increasing popularity of outdoor camping and urban living, the demand for in-vehicle storage equipment is showing a diversified development trend. Commonly used in-vehicle storage equipment, such as folding tables and insulated boxes, are usually independent components, which have problems such as needing to be stored separately when carrying them, being cumbersome to carry, and taking up a lot of space.

[0003] Considering equipment deployment efficiency, the existing solution of integrating the vehicle-mounted folding table into the spare tire cover adds a desktop function to the original spare tire cover, reducing the number of accessories. Furthermore, there is a desire to combine the folding table with an insulated box to achieve multiple functions such as drag-and-drop movement, storage, and a desktop for placing items. This places high demands on the connection structure between the folding table and the insulated box.

[0004] The existing solution involves installing connectors on the folding table and the insulated box separately. This structure has problems such as complicated disassembly and assembly and unstable connection. In particular, it cannot meet the requirements of dragging and dropping scenarios. Furthermore, installing connectors in multiple places on the folding table will cause significant changes to the spare tire cover structure, reduce the structural strength, and affect the original function and versatility of the spare tire cover. Utility Model Content

[0005] The purpose of this utility model is to provide a linkage locking structure between a spare tire cover folding table and an insulated box, so as to enable the folding table and the insulated box to be easily combined and disassembled, and to ensure the stability of the structure in the combined state.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A linkage locking structure for a spare tire cover folding table and an insulated box includes a folding table and an insulated box cover. The insulated box cover is provided with a first fastener, which includes a first fixing part that abuts against the surface of the insulated box cover and a first arched part that forms a gap with the surface of the insulated box cover. A plurality of first fixing parts and first arched parts are alternately provided, and one of the first fixing parts is provided with a lock hole.

[0008] The folding table is provided with a second fastener and a locking fastener. The second fastener includes a second fixing part that abuts against the surface of the folding table and a second arched part that forms a gap with the surface of the folding table. Several second fixing parts and second arched parts are alternately arranged, and the second arched parts correspond one-to-one with the first arched parts. The locking fastener includes a retractable locking tongue.

[0009] When the folding tabletop and the insulated box lid are combined, the first arched part is inserted between the second arched part and the folding tabletop, the second arched part is inserted between the first arched part and the insulated box lid, and the locking tongue is inserted into the lock hole.

[0010] As an optional solution, the locking mechanism also includes a fixed base and a handle. The fixed base is embedded in the folding tabletop, and the handle is inserted into the fixed base from the upper surface of the folding tabletop. The locking tongue is installed at the lower end of the handle and extends out of the fixed base. A spring is provided in the fixed base, and the spring exerts a downward force on the locking tongue.

[0011] As an optional solution, the locking mechanism also includes a fixed base and a handle. The fixed base is embedded in the folding tabletop, and the handle is inserted into the fixed base from the upper surface of the folding tabletop. The locking tongue is installed at the lower end of the handle and extends out of the fixed base. The locking tongue is a magnetic material, and a magnetic block is provided in the lock hole to form a magnetic attraction with the locking tongue.

[0012] As an alternative, the width of the first fastener is the same as the width of the second fastener, and a first notch is provided between the adjacent first fixing part and the first arched part, the length of the first notch being half the width of the first fastener; a second notch is provided between the adjacent second fixing part and the second arched part, the length of the second notch being half the width of the second fastener.

[0013] As an alternative, the gap between the first arch and the top cover of the insulated box is equal to the thickness of the second arch; the gap between the second arch and the folding tabletop is equal to the thickness of the first arch.

[0014] As an alternative, the ends of the first arched portion and the ends of the second arched portion are respectively rounded.

[0015] As an alternative, the first fixing part and / or the second fixing part are provided with elastic damping plates. When the folding table and the insulated box cover are combined, the elastic damping plates are clamped by the first and second fasteners.

[0016] As an alternative, the first fixing parts at both ends of the first fastener are respectively provided with first fixing holes; the second fixing parts at both ends of the second fastener are respectively provided with second fixing holes.

[0017] The beneficial effects of this utility model are:

[0018] The linkage locking structure between the spare tire cover folding table and the insulated box uses a first and second buckle to quickly and initially connect the folding table to the insulated box lid. Then, the first and second buckles are locked in place by a locking mechanism to achieve a secondary locking between the folding table and the insulated box lid. The connection structure is stable and reliable, and can meet the stability requirements even during dragging. This allows the assembly to have multiple functions, including movement, storage, and tabletop placement, and is more convenient to disassemble and store. Attached Figure Description

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the terms "first" and "second" are merely used to distinguish between different terms in description and do not have any special meaning.

[0031] Please see Figures 1 to 5 As shown, this embodiment provides a linkage locking structure between a spare tire cover folding table and an insulated box, including a folding table 1 and an insulated box cover 2. The insulated box cover 2 is provided with a first buckle 3. The first buckle 3 includes a first fixing part 31 that abuts against the surface of the insulated box cover 2 and a first arched part 32 that forms a gap with the surface of the insulated box cover 2. A plurality of first fixing parts 31 and first arched parts 32 are alternately arranged. One of the first fixing parts 31 is provided with a lock hole 33.

[0032] The folding tabletop 1 is provided with a second fastener 4 and a locking fastener 5. The second fastener 4 includes a second fixing part 41 that abuts against the surface of the folding tabletop 1 and a second arched part 42 that forms a gap with the surface of the folding tabletop 1. A plurality of second fixing parts 41 and second arched parts 42 are alternately arranged, and the second arched parts 42 correspond one-to-one with the first arched parts 32. The locking fastener 5 includes a retractable locking tongue 51.

[0033] When the folding tabletop 1 and the insulated box cover 2 are combined, the first arched part 32 is inserted between the second arched part 42 and the folding tabletop 1, the second arched part 42 is inserted between the first arched part 32 and the insulated box cover 2, and the locking tongue 51 is inserted into the locking hole 33.

[0034] In this embodiment, taking three first fixing parts 31, two first arched parts 32, three second fixing parts 41, and two second arched parts 42 as an example, the locking hole 33 is located on the first fixing part 31 in the middle position, satisfying the connection requirements between the first fastener 3 and the second fastener 4. Based on this, the number of the first fixing parts 31, the first arched parts 32, the second fixing parts 41, and the second arched parts 42 can be increased or decreased.

[0035] Therefore, by using the first buckle 3 and the second buckle 4 to connect together, the folding tabletop 1 and the insulated box cover 2 can be quickly and initially connected. Then, the first buckle 3 and the second buckle 4 are locked by the locking buckle 5 to achieve a secondary locking between the folding tabletop 1 and the insulated box cover 2. The connection structure is stable and reliable, and can meet the stability requirements even during dragging. This allows the assembly to have multiple functions such as movement, storage, and tabletop placement, making it more convenient to disassemble and store.

[0036] Optionally, the locking fastener 5 also includes a fixed base 52 and a handle 53. The fixed base 52 is embedded in the folding tabletop 1, and the handle 53 is inserted into the fixed base 52 from the upper surface of the folding tabletop 1. The locking tongue 51 is installed at the lower end of the handle 53 and extends out of the fixed base 52. A spring 54 is provided in the fixed base 52, and the spring 54 gives the locking tongue 51 a downward force.

[0037] The fixed base 52 is combined with the folding table 1 through a non-invasive fixing method (such as sewing or embedded riveting). The folding table 1 here directly uses the original spare tire cover. The handle 53 is the inherent structure of the spare tire cover (generally a cloth strap ring, used to lift the spare tire cover). The fixed base 52 is directly combined with the handle 53, which can reduce the need to modify the spare tire cover.

[0038] Therefore, when the first buckle 3 and the second buckle 4 are engaged, the locking tongue 51 at the end of the handle 53 is automatically inserted into the lock hole 33 under the tension of the spring 54, forming a secondary locking; when the user pulls the handle 53, the locking tongue 51 is compressed by the reverse force of the spring 54, and after disengaging from the lock hole 33, the top cover 2 of the insulated box and the folding table 1 can be separated.

[0039] Alternatively, the locking element 5 can be locked without relying on the force of the spring 54, using a magnetic-assisted locking method. In this case, the spring 54 design is eliminated, the latch 51 is a magnetic body, and a magnetic block is provided in the lock hole 33 to form a magnetic attraction with the latch 51.

[0040] Therefore, when the first buckle 3 and the second buckle 4 are engaged, the locking tongue 51 at the end of the handle 53 is automatically inserted into the lock hole 33 under magnetic attraction, forming a secondary locking; when the user pulls the handle 53, the locking tongue 51 is freed from the magnetic force and disengages from the lock hole 33, thus separating the insulated box cover 2 from the folding table 1.

[0041] Specifically, the width of the first fastener 3 is the same as or substantially the same as the width of the second fastener 4, and a first notch 34 is provided between the adjacent first fixing part 31 and the first arched part 32. The length of the first notch 34 is approximately half the width of the first fastener 3; a second notch 43 is provided between the adjacent second fixing part 41 and the second arched part 42. The length of the second notch 43 is approximately half the width of the second fastener 4.

[0042] Therefore, the first notch 34 and the second notch 43, which are half the width of the first notch, allow the first buckle 3 and the second buckle 4 to be aligned and stacked when they are inserted, thus reducing the space occupied.

[0043] Specifically, the gap between the first arched portion 32 and the top cover 2 of the insulated box is approximately equal to the thickness of the second arched portion 42; the gap between the second arched portion 42 and the folding tabletop 1 is approximately equal to the thickness of the first arched portion 32.

[0044] This results in an interference fit when the first buckle 3 and the second buckle 4 are interlocked, achieving initial locking and ensuring that the folding table 1 and the insulated box cover 2 do not loosen during dragging.

[0045] Optionally, the ends of the first arched portion 32 and the second arched portion 42 are respectively rounded.

[0046] This allows the first latching member 3 and the second latching member 4 to be smoothly and accurately connected, thereby improving the service life of the first arched part 32 and the second arched part 42.

[0047] Optionally, an elastic damping sheet 6 is provided on the first fixing part 31 and / or the second fixing part 41. When the folding table board 1 and the insulated box cover 2 are combined, the elastic damping sheet 6 is clamped by the first fastener 3 and the second fastener 4.

[0048] The elastic damping plate 6 can be made of rubber to buffer vibrations and improve the structural stability of the first and second fasteners 3 and 4 in the locked state, preventing slippage and gaps. Alternatively, the elastic damping plate 6 can be made of silicone bellows to further enhance locking stability.

[0049] Optionally, the first fixing part 31 at both ends of the first buckle 3 is provided with a first fixing hole 35; the second fixing part 41 at both ends of the second buckle 4 is provided with a second fixing hole 44.

[0050] Thus, the first fastener 3 can be simply set on the insulated box cover 2, and the second fastener 4 can be simply set on the folding table 1, reducing modification costs and improving the applicability of spare tire covers and insulated boxes for various vehicle models.

[0051] In summary, the linkage locking structure between the spare tire cover folding table and the insulated box has the following advantages:

[0052] 1) By using the special-shaped first buckle 3 and second buckle 4 to connect, a stable connection can be achieved between the insulated box lid 2 and the folding table 1. No tools are required for quick assembly and disassembly, which improves the efficiency of camping equipment deployment.

[0053] 2) The insertion of the first fastener 3 and the second fastener 4 achieves the initial locking of the insulated box cover 2 and the folding table 1, and the locking fastener 5 achieves the secondary locking, ensuring the reliable connection between the insulated box cover 2 and the folding table 1, and ensuring structural stability even under dragging conditions.

[0054] 3) Based on the original design of the spare tire cover, the locking fastener 5 is integrated, which can reduce the number of additional parts and eliminate the need for additional holes. This reduces production costs while preserving the original structural integrity of the spare tire cover.

[0055] 4) The locking fastener 5 relies solely on the handle 53 structure, which can be adapted to the spare tire cover material and size of different vehicle models; the first fastener 3 and the second fastener 4 are easy to install and can be adapted to almost all insulated box covers 2 and folding table panels 1, with low modification costs.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
