Description

Technical Field

[0001] This utility model belongs to the technical field of roof tent panel components, specifically relating to a waterproof connection structure for roof tent panels. Background Technology

[0002] With the continuous growth of private car ownership, self-driving tours have become one of the mainstream travel methods. Their advantages lie in avoiding ground moisture and insect infestations through their off-ground design, and the interior height after unfolding typically reaches 1.4 meters, with a sleeping area exceeding 2.4 square meters, significantly improving camping comfort. However, existing products still face technical bottlenecks in waterproofing and structural reliability, hindering further market expansion.

[0003] Traditional rotating folding rooftop tents use a single hinge to connect two folding panels, with the tent fabric folded into the gap between the panels. In this design, when folded, rainwater can easily seep into the interior through the panel seams. The seeping moisture cannot escape in the enclosed space, leading to an increased rate of mold growth on the tent fabric and faster corrosion of the metal hinge. Summary of the Invention

[0004] Technical problems to be solved This utility model addresses the aforementioned deficiencies in existing technologies by proposing a waterproof connection structure for rooftop tent panels. A connecting mechanism splices two base plates into a single unit, and a waterproof sealant prevents rainwater from entering the rooftop tent through the connection point, thus achieving a waterproof seal. This solves the problem of traditional rotating folding rooftop tents, which use a single hinge to connect two folding panels. When the tent fabric is folded into the gap between the panels, rainwater easily seeps into the interior through the panel seams in the folded state. The infiltrated moisture cannot drain out in the sealed space, leading to increased mold growth on the tent fabric and accelerated corrosion of the metal hinge.

[0005] Technical solution To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a waterproof connection structure for roof tent panels, comprising a first base plate and a second base plate that are hinged together, and a waterproof seal is provided between the first base plate and the second base plate. In the unfolded state, the first substrate and the second substrate are on the same plane or nearly on the same plane; In the folded state, the first substrate and the second substrate are in a vertical or nearly vertical state; The adjacent side edges of the first substrate and the second substrate are respectively provided with a first connecting part and a second connecting part for hinge connection. The waterproof seal has fixing parts on both sides, which are connected to the first substrate and the second substrate respectively. The waterproof seal is used for waterproof sealing at the hinge of the first connecting part and the second connecting part.

[0006] In some embodiments, the fixing part has a cylindrical or polygonal cross section, and a thin protective part is provided between the two fixing parts. The first substrate and the second substrate are both provided with mounting grooves that match the fixing parts, and the mounting grooves are also provided with an opening that communicates with the outside and allows the protective part to pass through.

[0007] In some embodiments, when the first substrate and the second substrate are in the unfolded state, the corresponding roof tent is also in the unfolded state, and the waterproof seal is located outside the roof tent and is in an unstretched initial state or a preliminary stretched state. The first and second substrates are in a folded state, and the corresponding rooftop tent is also in a folded state. The waterproof seal is located outside the rooftop tent and is in a further stretched state.

[0008] In some embodiments, the first connecting portion and the second connecting portion are each provided with a corresponding first abutting component. In the unfolded state, the first connecting portion and the second connecting portion also maintain the first substrate and the second substrate in the same plane state through the first abutting component. The first abutting component consists of two 90° substrate apex corners located on one side of the first connecting portion and the second connecting portion, respectively.

[0009] In some embodiments, the first connecting portion includes a first limiting hook extending outward from the abutting surface of the first abutting component along the abutting surface of the first substrate. The second connecting part includes a second limiting hook that extends inward along the abutting surface of the first abutting component towards the second substrate and engages with the first limiting hook. The outer wall of the groove formed by the first limiting hook is an arc-shaped curved surface, and the inner wall of the second limiting hook is an arc-shaped curved surface, realizing the rotational hinge of the first limiting hook and the second limiting hook.

[0010] In some embodiments, the second limiting hook has a fixing groove inside, and the top of the hook portion of the first limiting hook has a fixing block that matches the fixing groove.

[0011] In some embodiments, a second abutting component at the abutting point where the first substrate and the second substrate are in a folded state is provided with a folding buffer pad, which is disposed on the first substrate or the second substrate. The first substrate and the second substrate are also kept in a folded vertical state by a second abutting component.

[0012] In some embodiments, the second abutting component is located on the other side of the first connecting portion and the second connecting portion corresponding to the first abutting component, including a substrate V-groove with an included angle of 135° on the first connecting portion, and a substrate apex angle with an outer tip angle of 135° on the second connecting portion.

[0013] In some embodiments, the folded buffer pad covers the top corner of the substrate with an external tip angle of 135° on the second connection portion, and the folded buffer pad is fixed to both sides of the top corner of the substrate.

[0014] In some embodiments, a T-shaped groove and a circular groove are provided on both sides of the apex corner of the substrate with an external tip angle of 135° on the second connecting part; One end of the folded buffer pad is provided with a T-shaped fixing block that matches the T-slot, and the other end of the folded buffer pad is provided with a circular fixing block that matches the circular slot.

[0015] Beneficial effects Compared with the prior art, this utility model splices two base plates into a whole through a connecting mechanism, and prevents rainwater from entering the interior of the roof tent through a waterproof seal, thus playing a waterproof and sealing role. This effectively realizes the waterproof function of the connecting parts of the roof tent panels and protects the dry environment inside the roof tent.

[0016] Specifically, the waterproof seal features an elastic stretch design in its folded / unfolded state, ensuring continuous sealing during movement and preventing leakage caused by insufficient deformation of traditional static seals. It also ensures the accuracy of the unfolded plane through a first abutting component with a 90° apex angle, and a second abutting component with a 135° V-groove locks the folded vertical state, improving structural stability.

[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example 1

[0026] like Figures 1-5 As shown, the waterproof connection structure of this embodiment includes a first substrate 10 and a second substrate 1 that are hinged together, and a waterproof seal 3 is also provided between the first substrate 10 and the second substrate 1. In the unfolded state, the first substrate 10 and the second substrate 1 are on the same plane or nearly on the same plane; in the folded state, the first substrate 10 and the second substrate 1 are perpendicular or nearly perpendicular. In this embodiment, in the unfolded state, the first substrate 10 and the second substrate 1 are on the same plane, and in the folded state, the first substrate 10 and the second substrate 1 are perpendicular. The adjacent side edges of the first substrate 10 and the second substrate 1 are respectively provided with a first connecting portion 4 and a second connecting portion 5 for hinge connection; the waterproof seal 3 is provided with fixing portions 32 on both sides, which are connected to the first substrate 10 and the second substrate 1 respectively through the fixing portions 32. The waterproof seal 3 is used for waterproof sealing at the hinge of the first connecting portion 4 and the second connecting portion 5. This is the core of this embodiment. Considering the overall structure of the rooftop tent, such as... Figure 7 As shown, a first base plate 10 is provided on each of the left and right sides of the second base plate 1. One first base plate 10 serves as the lower cover of the rooftop tent, and the other first base plate 10 serves as the upper cover of the rooftop tent. The lower cover and the upper cover are fastened together and are in a folded state. When opened, the inner tent is spread out, and the two first base plates 10 and one second base plate 1 unfold and are all located on the same plane to form the inner bottom plate of the tent. Therefore, since rooftop tents are generally used by users outdoors, the sealing is very important for wind and water protection. However, the first connecting part 4 and the second connecting part 5, which are only hinged, cannot effectively achieve waterproof sealing.

[0027] Regarding how to achieve sealing, specifically, the cross-section of the fixing part 32 is cylindrical or polygonal, and a thin protective part 31 is provided between the two fixing parts 32. The first substrate 10 and the second substrate 1 are both provided with mounting grooves 33 that match the fixing parts 32, and the mounting grooves 33 are also provided with an opening 34 that communicates with the outside and allows the protective part 31 to pass through.

[0028] When the first substrate 10 and the second substrate 1 are in the unfolded state, the corresponding rooftop tent is also in the unfolded state. The waterproof seal 3 is located outside the rooftop tent and is in the initial state of not being stretched or in the initial stretched state. The initial state means that the waterproof seal 3 is not under stress. When the first substrate 10 and the second substrate 1 are in a folded state, the rooftop tent is also in a folded state. The waterproof seal 3 is located outside the rooftop tent and is in a further stretched state. When the rooftop tent is changed from an unfolded state to a folded state, the protective part 31 of the waterproof seal 3 is stretched along the distance between the mounting grooves 33 on the first substrate 10 and the second substrate 1. The waterproof seal 3 is prevented from falling out by the cooperation design between the mounting grooves 33 and the openings 34. The waterproof seal 3 is generally made of elastic silicone or rubber material, which can effectively improve the sealing effect.

[0029] Furthermore, the first connecting part 4 and the second connecting part 5 are each provided with a corresponding first abutting component 7. When unfolded, the first connecting part 4 and the second connecting part 5 also maintain the first substrate 10 and the second substrate 1 in the same plane state through the first abutting component 7. The first abutting component 7 consists of two 90° substrate apex corners located on one side of the first connecting part 4 and the second connecting part 5, that is, the abutting is achieved through the apex corners of the first substrate 10 and the second substrate 1 themselves, and the two 90° substrate apex corners can ensure that the two are in the same plane after unfolding.

[0030] like Figure 2 , Figure 3As shown, the first connecting part 4 includes a first limiting hook 41 extending outward from the abutting surface of the first abutting component 7 towards the first substrate 10, and the second connecting part 5 includes a second limiting hook 51 extending inward from the abutting surface of the first abutting component 7 towards the second substrate 1, which overlaps and engages with the first limiting hook 41; the outer wall of the groove formed by the first limiting hook 41 is an arc-shaped curved surface, and the inner wall of the second limiting hook 51 is an arc-shaped curved surface, realizing the rotational hinge of the first limiting hook 41 and the second limiting hook 51; the core purpose of the structural design of the first limiting hook 41 and the second limiting hook 51 is to ensure the smooth rotation of the first substrate 10 and the second substrate 1. This design allows the first and second limiting hooks to have the same radius of curvature, reducing rotational friction and ensuring they do not detach. Specifically, the outer wall of the groove formed by the first limiting hook 41 is an arc-shaped surface, and the inner wall of the second limiting hook 51 is an arc-shaped surface. The abutment design of the arc-shaped surfaces achieves smooth rotation. Furthermore, a fixing groove is provided inside the second limiting hook 51, and a fixing block matching the fixing groove is provided at the top of the hook of the first limiting hook 41, thereby improving the firmness of the fit and preventing it from coming off during normal rotation. Installation or disassembly can be achieved by staggered insertion.

[0031] The first limiting hook 41 is designed with a downward bend and is located on the upper side of the first connecting part 4. It bends downward from the side edge of the first connecting part 4 to form a hook shape, with a certain curvature on the inner side to better match the second limiting hook 51. The second limiting hook 51 is an upward bend and is located on the lower side of the second connecting part 5. It bends upward from the side edge of the second connecting part 5 to form a hook shape, and the shape and curvature of the hook match the first limiting hook 41. The material and design requirements of the second limiting hook 51 are consistent with those of the first limiting hook 41 to ensure the reliability and stability of the connection. When the first limiting hook 41 and the second limiting hook 51 are connected, they form an approximately circular structure. This circular structure is formed because the downward bend of the first limiting hook 41 and the upward bend of the second limiting hook 51 interlock, and the inner curvatures of the hooks fit together, making the connection part form a closed, relatively regular circular contour. This allows for a more even distribution of the force during connection, improving the strength and stability of the connection. Example 2

[0032] Compared to Example 1, such as Figure 6 As shown, a folding buffer pad 6 is provided at the contact point between the first substrate 10 and the second substrate 1 in the folded state. The folding buffer pad 6 is disposed on the first substrate 10 or the second substrate 1. The first substrate 10 and the second substrate 1 are also kept in a folded vertical state by the second contact component 8. The folding buffer pad 6 is used to achieve a buffering effect when the first substrate 10 and the second substrate 1 are in contact after folding, and at the same time plays a protective role for the first substrate 10 and the second substrate 1.

[0033] The second abutting component 8 is located on the other side of the first connecting part 4 and the second connecting part 5 corresponding to the first abutting component 7, including a substrate V-groove with an included angle of 135° on the first connecting part 4, and a substrate apex angle with an outer tip angle of 135° on the second connecting part 5.

[0034] The folded buffer pad 6 covers the top corner of the substrate with an external tip angle of 135° on the second connecting part 5, and the folded buffer pad 6 is fixed to both sides of the top corner of the substrate.

[0035] The second connecting part 5 has T-shaped grooves 52 and circular grooves 53 on both sides of the apex corner of the substrate with an external tip angle of 135°. One end of the folded buffer pad 6 is provided with a T-shaped fixing block 61 that matches the T-shaped groove 52, and the other end is provided with a circular fixing block 62 that matches the circular groove 53. Specifically, the T-shaped fixing block 61 is located at one end of the folded buffer pad 6, and its shape matches the T-shaped groove 52. The width of the horizontal portion of the "T" shape is slightly smaller than the opening width of the T-shaped groove 52, so that it can smoothly pass through the opening and enter the cavity; the length and width of the vertical portion are adapted to the cavity size of the T-shaped groove 52, ensuring a close fit after entering the cavity and achieving a stable connection. The circular fixing block 62 is located at the other end of the folded buffer pad 6, and its shape is circular, matching the circular groove 53. The diameter of the circular fixing block 62 is slightly smaller than the diameter of the circular groove 53, allowing it to easily embed into the circular groove 53 and rotate and slide freely within the groove.

[0036] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
