[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0028] The following is for reference. Figures 1-9 Description of a support leg assembly 100 according to an embodiment of the present utility model.

[0029] Reference Figures 1-3 As shown, the support leg assembly 100 of the first aspect embodiment of the present invention includes: a plurality of support legs 1, a first connecting rod 2, and an adjustment and fixing structure 3. The first connecting rod 2 is rotatably connected between two support legs 1 spaced apart along a first direction to adjust the distance between the two support legs 1 in the first direction. The first connecting rod 2 includes: an inner tube 21 and an outer tube 22. A portion of the outer tube 22 is sleeved on the inner tube 21, and the outer tube 22 can move relative to the length direction of the inner tube 21. The adjustment and fixing structure 3 is disposed at the connection between the inner tube 21 and the outer tube 22, thereby selectively adjusting the relative length of the inner tube 21 and the outer tube 22.

[0030] Specifically, the support leg assembly 100 mainly consists of multiple support legs 1, a first connecting rod 2, and an adjustment and fixing structure 3. The first connecting rod 2 is rotatably connected between two support legs 1 spaced apart along a first direction. Since the first connecting rod 2 is located between the two support legs 1, it can provide a certain supporting force to the two support legs 1, thereby preventing deformation between the two support legs 1. Furthermore, since the first connecting rod 2 can rotate between the two support legs 1, the distance between the two support legs 1 can be adjusted. For example, the distance between the two support legs 1 can be increased or decreased, thereby enabling the support legs 1 to be extended and retracted.

[0031] Furthermore, the first connecting rod 2 is mainly composed of an inner tube 21 and an outer tube 22. A part of the outer tube 22 is sleeved on the inner tube 21, so that the inner tube 21 can move inside the outer tube 22, thereby realizing the extension and retraction of the first connecting rod 2.

[0032] Furthermore, the adjusting fixing structure 3 is set at the connection between the inner tube 21 and the outer tube 22, thereby selectively adjusting the relative length of the inner tube 21 and the outer tube 22. Specifically, when the trunk cover 5 is rectangular, the inner tube 21 and the outer tube 22 of the first connecting rod 2 can be unlocked by adjusting the fixing structure 3, which can increase the relative length of the inner tube 21 and the outer tube 22. This can lengthen the distance between the two support legs 1 set at intervals in the first direction. After the multiple support legs 1 are unfolded, they are also rectangular. Thus, the multiple support legs 1 can fit the rectangular trunk cover 5. The length-to-width ratio of the rectangular trunk cover 5 can be adjusted with the first connecting rod on the support leg 1. This allows the support leg 1 to be located at the edge of the rectangular trunk cover 5, thereby playing a role in stabilizing and supporting the rectangular trunk cover 5. Similarly, the first connecting rod between multiple support legs 1 can be adjusted by adjusting the fixing structure 3 so that the distance between two adjacent support legs 1 is equal. In this way, the multiple support legs 1 can be unfolded into a square, which can play a role in stabilizing and supporting the square trunk cover 5.

[0033] Therefore, the support leg assembly 100 can effectively support the edge of the square or rectangular trunk cover 5, providing high support stability and preventing the trunk cover 5 and the support leg assembly 100 from tipping over when heavy objects are placed at the edge of the trunk cover 5.

[0034] According to some embodiments of this utility model, such as Figure 2 and Figure 7 As shown, the adjusting and fixing structure 3 includes a threaded tube 31 and a fastener 32. The threaded tube 31 is connected to the outer tube 22 and is partially sleeved on the inner tube 21. The fastener 32 is partially threaded with the threaded tube 31, thereby fixing the inner tube 21 and the outer tube 22.

[0035] The threaded tube 31 is fixedly connected to the outer tube 22, for example, by rivets. The threaded tube 31 partially fits over the inner tube 21, facilitating its compression. The fastener 32 partially engages with the threaded tube 31's threads, allowing it to be tightened clockwise or loosened counter-clockwise. When the support leg assembly 100 is deployed, the fixing structure 3 is adjusted to secure the inner tube 21 and outer tube 22, improving their stability. Specifically, by increasing the depth of the threaded engagement of the fastener 32 with the threaded tube 31, the fastener 32 can compress the inner tube 21, preventing movement of the inner tube 21 relative to the outer tube 22 and thus securing the inner and outer tubes.

[0036] Furthermore, by reducing the depth of the threaded insertion of the fastener 32 into the threaded tube 31, the fastener 32 can be loosened from the inner tube 21, thereby allowing the inner tube 21 to move relative to the outer tube 22.

[0037] According to some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the threaded pipe 31 includes: a first pipe section 311 and a second pipe section 312. The first pipe section 311 is connected to the outer pipe 22, and the second pipe section 312 is connected to the first pipe section 311. The second pipe section 312 is provided with an external thread on its outer periphery. The second pipe section 312 is sleeved on the inner pipe 21, and the fastener 32 is threaded with the external thread.

[0038] The threaded pipe 31 is mainly composed of a first pipe section 311 and a second pipe section 312. The first pipe section 311 can be fixedly connected to the outer pipe 22 by rivets. The second pipe section 312 has external threads on its outer circumference. The fastener 32 can be set as a nut. The fastener 32 is threaded with the external thread of the second pipe section 312. In this way, the fastener 32 can be used to tighten and loosen the inner pipe 21.

[0039] According to some embodiments of this utility model, such as Figure 9 As shown, the second pipe section 312 is provided with an opening groove 3121, which extends along the length of the second pipe section 312.

[0040] When the fastener 32 is tightened with the external thread of the second pipe section 312, the opening groove 3121 provides sufficient clamping space for the second pipe section 312 to press against the inner pipe 21, thus facilitating the fixation of the inner pipe 21 and the outer pipe 22. When the fastener 32 is loosened from the external thread of the second pipe section 312, the opening groove 3121 allows the second pipe section 312 to quickly loosen the inner pipe 21, thus facilitating the movement of the inner pipe 21 relative to the outer pipe 22.

[0041] According to some embodiments of this utility model, such as Figure 7 As shown, a protrusion 33 is provided at one end of the threaded tube 31 near the outer tube 22. The protrusion 33 protrudes away from the threaded tube 31 and is used to hang the flexible belt 8.

[0042] The flexible belt 8 can be set as an elastic long rope or nylon belt. The protruding part 33 is set to effectively prevent the flexible belt 8 from slipping or shifting during use, and acts as a stop. This ensures that the flexible belt 8 is always in the predetermined position, thereby improving the stability of the flexible belt 8.

[0043] Furthermore, when the support leg 1 is extended, the flexible band 8 is taut, indicating that the support leg 1 has been fully extended. In addition, the flexible band 8 can also be used as a strap to hang items during the use of the support leg 1, such as spoons, water cups, speakers, etc. for outdoor activities.

[0044] According to some embodiments of this utility model, such as Figure 2 As shown, the support leg 1 includes: a base 11, a support rod 12 and a top cover 13. The bottom of the support rod 12 is connected to the base 11, and the top of the support rod 12 is connected to the top cover 13. One of the outer tube 22 and the inner tube 21 is rotatably connected to the base 11 of one support leg 1, and the other of the outer tube 22 and the inner tube 21 is rotatably connected to the top cover 13 of the other support leg 1.

[0045] The bottom of the support rod 12 is connected to the base 11. The base 11 can provide a certain support for the support rod 12 and can also increase the contact area, so that the support leg 1 can be more stable after it is deployed.

[0046] Furthermore, one of the outer tube 22 and the inner tube 21 is rotatably connected to the base 11 of one support leg 1. That is, the outer tube 22 can be rotatably connected to the base 11 of the support leg 1, or the inner tube 21 can be rotatably connected to the base 11 of the support leg 1. When the outer tube 22 is rotatably connected to the base 11 of the support leg 1, the inner tube 21 is correspondingly rotatably connected to the top cover 13 of the other support leg 1. When the inner tube 21 is rotatably connected to the base 11 of the support leg 1, the outer tube 22 is correspondingly rotatably connected to the top cover 13 of the other support leg 1. In this way, the first connecting rod 2 can be tilted and rotated easily.

[0047] According to some embodiments of this utility model, such as Figure 6 As shown, the top of the top cover 13 is provided with a first plug-in portion 131, which is used to detachably connect with the cover plate connector 6.

[0048] The cover plate 5 is detachably connected to the first insertion part 131 of the top cover 13 via the cover plate connector 6. In this way, the connection or separation of the top cover 13 and the cover plate 5 can be completed without the use of tools or with only simple operation, thereby improving the assembly and disassembly efficiency of the top cover 13 and the cover plate connector 6.

[0049] According to some embodiments of this utility model, such as Figure 6 As shown, the first insertion part 131 is constructed as an insertion groove, with the groove opening facing the outer corner of the top cover 13.

[0050] Specifically, the insertion groove is a U-shaped groove with a clear opening guide structure. When the cover plate connector 6 approaches the insertion groove, even if there is a slight positional deviation, it can be automatically guided into the groove through the opening edge of the U-shaped groove.

[0051] Furthermore, the slot of the insertion groove faces the outer corner of the top cover 13 (i.e., the outer edge of the top cover 13). This allows the operator to directly observe and insert the device from the outside without having to align it vertically from above. It enables side or oblique insertion, making the operation more intuitive and convenient.

[0052] Furthermore, the insertion slot is a U-shaped slot. The three-sided U-shaped structure provides good lateral support and limiting, which can prevent loosening or detachment from the cover plate connector 6, thereby improving the connection stability between the insertion slot and the cover plate connector 6.

[0053] According to some embodiments of this utility model, such as Figure 3 As shown, the outer wall of the top cover 13 is provided with hooks 4, which are used to hang items.

[0054] The hook 4 is located on the outer wall of the top cover 13, in a prominent and easily accessible position. Users can quickly retrieve hung items without opening the box or equipment, thus preventing loss and facilitating management and retrieval. In outdoor or emergency scenarios (such as camping or disaster relief), it can quickly hang and retrieve equipment such as flashlights and walkie-talkies, thereby improving response speed.

[0055] According to some embodiments of this utility model, such as Figure 3 As shown, an elastic pad 14 is provided on the bottom surface of the base 11.

[0056] The elastic pad 14 can be made of PVC. Since PVC pads are elastic, they can reduce the impact of the ground on the support leg 1. Moreover, the elastic pad 14 usually has a high coefficient of friction, which can effectively increase the friction between the base 11 and the support surface (such as a desktop, ground, or metal platform), thereby preventing the support leg 1 from sliding or shifting due to slight vibration, tilting, or external force.

[0057] According to some embodiments of this utility model, such as Figure 2 As shown, two first connecting rods 2 are provided between two support legs 1 spaced apart along the first direction. The two first connecting rods 2 are intersected at the middle and are rotatably connected to each other.

[0058] When the support leg assembly 100 is deployed, the two first connecting rods 2 can provide support to the two support legs 1 spaced apart in the first direction.

[0059] Furthermore, the two first connecting rods 2 are arranged in an X-shaped support structure, which effectively enhances the structural rigidity and overall stability between the two support legs 1. Since the two first connecting rods 2 are rotatably connected, the entire structure can be synchronously unfolded or folded by rotation, making operation simple and effortless. After the two first connecting rods 2 are folded, the support legs 1 are brought closer together, significantly reducing the space occupied, thus facilitating transportation and storage, and making it particularly suitable for outdoor use.

[0060] According to some embodiments of this utility model, such as Figure 2 As shown, the support leg assembly 100 further includes a second connecting rod, which is rotatably connected between two support legs 1 spaced apart along a second direction, thereby allowing the distance between the two support legs 1 to be adjusted in the second direction, wherein the first direction is perpendicular to the second direction.

[0061] The second connecting rod is rotatable and can be locked after adjustment. When folding, the support leg 1 can be retracted, causing the entire structure to fold towards the center. Combined with the first connecting rod 2 in the first direction, bidirectional folding can be achieved, which can significantly reduce the volume when folded, making it easy to carry and store.

[0062] Furthermore, the second connecting rod is rotatably connected between the two support legs 1 spaced apart along the second direction, allowing for adjustment of their spacing. This direction is perpendicular to the first direction, forming an orthogonal bidirectional adjustment structure. This structure can achieve bidirectional stable support, significantly improve terrain adaptability and anti-overturning ability, and also support quick adjustment and bidirectional folding, making it flexible to store and easy to carry.

[0063] like Figure 1 As shown, the trunk cover assembly 200 according to the second aspect of the present invention includes: a cover 5 and a support leg assembly 100 as described above, wherein a plurality of support legs 1 are detachably disposed at the bottom of the cover 5.

[0064] The support leg 1 is detachable, allowing the product to be removed when not in use, resulting in a more compact overall structure and significantly reduced transport volume. Users can choose whether to install the support leg 1 based on their actual needs. When the support leg 1 is not installed, the cover 5 can cover the trunk, concealing the toolbox or spare tire underneath. It can also be removed and used as a table for outdoor camping, thus achieving dual use as a table and trunk cover 5, increasing its applicability.

[0065] According to some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the trunk cover assembly 200 also includes a cover connector 6, which is disposed at the bottom of the cover 5. The cover connector 6 is provided with a second insertion part 61, which is inserted and engaged with the support leg 1.

[0066] Specifically, the cover plate connector 6 is located at the bottom of the cover plate 5, which facilitates the insertion and engagement of the cover plate 5 and the support leg 1. For example, the cover plate connector 6 is provided with a second insertion part 61, which can be configured as a protrusion. The top cover 13 of the support leg 1 is provided with a first insertion part 131, which can be configured as a slot. This facilitates the insertion and engagement of the second insertion part 61 and the support leg 1, and also facilitates the installation and disassembly of the cover plate connector 6 and the support leg 1.

[0067] According to some embodiments of this utility model, such as Figure 4 As shown, the bottom of the cover plate 5 is provided with four mounting parts 7. The shape formed by connecting the centers of the four mounting parts 7 in sequence is rectangular. There are four cover plate connectors 6, and the four cover plate connectors 6 correspond one-to-one with the four mounting parts 7.

[0068] The installation part 7 provides positioning for the cover plate connector 6, thereby enabling the rapid installation of the cover plate connector 6.

[0069] Furthermore, the cover plate connector 6 is pre-assembled on the cover plate 5. Each mounting part 7 on the cover plate 5 has three nuts pre-installed. Before installing the support leg 1, the cover plate connector 6 is first assembled on the cover plate 5 with screws. This cover plate connector 6 forms four points on the cover plate 5, which form a rectangle to fit the rectangular cover plate 5. The length and width ratio of the rectangle can be adjusted with the connecting rod on the support leg 1, thereby achieving the purpose of stably supporting the rectangular cover plate 5.

[0070] Specifically, the support leg assembly 100 has a telescopic function. Before unfolding, first loosen the fastener 32, then unfold the support leg 1, then fasten the cover plate connector 6 to the top cover 13, and then tighten the fastener 32 to achieve stable support for the cover plate 5. When retracting the support leg 1, first loosen the fastener 32, then detach the cover plate connector 6 from the top cover 13, and then retract the support leg 1. The cover plate connector 6 on the trunk cover 5 does not need to be removed, and the trunk cover 5 can be directly placed back into the car trunk.

[0071] For example, when the fastener 32 is set as a nut, before unfolding, first loosen the adjusting nut and unfold the support leg 1. At this time, the support rod 12 includes a large rod and a small rod. The small rod is fitted inside the large rod and can move freely up and down inside the large rod. The upper end of the large rod is connected to the top cover 13, and the lower end of the large rod is suspended. The lower end of the small rod is connected to the base 11, and the upper end of the small rod is suspended. When the support leg 1 is fully unfolded, the lower end of the large rod will abut against the base 11, and the upper end of the small rod will still be suspended, but will not swing inside the large rod.

[0072] Furthermore, the base 11 can be assembled with the first connecting rod 2 and the second connecting rod using rivets. The first connecting rod 2 and the second connecting rod can rotate relative to the base 11. When rotating, they can drive the entire support leg 1 to fold, thereby achieving the purpose of folding the entire support leg 1.

[0073] Among them, the vertical support rod 12 is an upright rod, the first connecting rod 2 in the first direction is an inclined rod, the first direction can be the length direction of the unfolded support leg assembly 100, and the second connecting rod in the second direction is also an inclined rod, the second direction can be the width direction of the unfolded support leg assembly 100.

[0074] The vehicle according to a third aspect of the present invention includes: the trunk cover assembly 200 of the above embodiment.
