Description

Technical Field

[0001] This utility model relates to the field of outdoor equipment technology, and in particular to a folding rooftop tent. Background Technology

[0002] With the continuous growth of private car ownership, self-driving tours have become a new tourism trend. Rooftop tents are tents that can be set up on the roof of a car. Because they are not close to the ground like other tents, they are less susceptible to ground moisture and dampness, making them more comfortable and popular. For example, the rooftop tent disclosed in announcement number CN206233680U. However, rooftop tents are quite high off the ground, and most use a hinged structure with several top poles and a base connected together. They are then rotated and raised using electric or pneumatic telescopic poles. The interior space is usually small, and unfolding and folding often requires multiple steps, making operation inconvenient. Furthermore, existing rooftop tents are quite thick when collapsed, easily generating significant wind resistance and noise; they are also heavy, causing a large upward shift of the center of gravity, increasing the risk of car swaying. Therefore, there is a need to design a rooftop tent that is more convenient to unfold and fold. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a folding rooftop tent.

The lower end of the second opening and closing beam is fixedly hinged to a fixed hinge seat, which is fixed to the base; the upper end of the second opening and closing beam is hinged to a movable hinge seat, which is slidably disposed on the opening and closing guide rail of the top cover. The first and second opening beams are hinged together at the middle; the electric strut is used to rotate the first or second opening beam around the fixed hinge seat so that the roof can be moved upward to unfold the roof tent, or moved downward to fold the roof tent.

[0005] Optionally, it also includes an external support assembly; an external support assembly is respectively provided on opposite sides of the base and the top cover in the second direction; the second direction is perpendicular to the first direction; when the top cover moves upward to unfold the roof tent, the external support assembly is used to support the top cover on opposite sides of the base in the second direction.

[0006] Optionally, the external support assembly includes a central movable joint, an upper external support rod, and a lower external support rod; the upper and lower external support rods are respectively hinged to both ends of the central movable joint; the upper end of the upper external support rod is hinged to the top cover, and the lower end of the lower external support rod is hinged to the base; the upper and lower external support rods are rotatable around the central movable joint.

[0007] Optionally, when the roof is moved upwards to unfold the roof tent, the upper and lower outer struts overlap vertically or partially overlap.

[0008] Optionally, the central movable joint extends along the second direction and can be connected to two sets of upper and lower outer struts at the head and tail ends, respectively.

[0014] The beneficial effects of this utility model are as follows: This application uses an electric strut to directly drive the first or second opening beam to rotate around the fixed hinge seat. Combined with the central hinge structure of the first and second opening beams, and the sliding engagement between the movable hinge seat and the opening / closing guide rail, the top cover can move directly upwards to unfold and downwards to fold. The opening and closing components are symmetrically arranged on both sides in the first direction, forming a dual-sided synchronous drive and support, avoiding structural tilting caused by unilateral force. The first and second opening beams form a cross-hinged linkage mechanism, which, combined with the directional sliding of the movable hinge seat along the opening / closing guide rail, ensures precise and controllable movement trajectory of the top cover during unfolding and folding, without jamming or deviation. After unfolding, the linkage mechanism forms a stable triangular support force system, effectively distributing the load on the top cover and inside the tent, improving the overall load-bearing capacity of the tent, and enabling it to withstand the impact of complex outdoor environments such as wind and rain, reducing the risk of structural deformation. This application utilizes a "sliding up and down" top cover for deployment, eliminating the need for rotation space and maximizing the vertical space between the base and the top cover. This results in a more organized and spacious interior, enhancing user comfort. Furthermore, the rectangular base and top cover are highly adaptable, allowing for flexible design based on vehicle roof dimensions and accommodating various car models, thus offering wider versatility. Additionally, when the roof tent is folded, the top cover fits snugly against the base. The overall thickness of the roof tent is approximately 10 centimeters, resulting in low wind resistance and noise during driving. Its lighter weight also reduces the upward shift of the center of gravity.

[0022] Example Reference Figures 1 to 3 The present invention proposes a folding rooftop tent, comprising: a base 10, a top cover 20, and an opening and closing assembly 30; The outer contours of the base 10 and the top cover 20 are rectangular plate-shaped structures that fit each other, and an opening and closing component 30 is provided on each of the opposite sides in the first direction. The opening and closing assembly 30 includes a first opening and closing beam 31, a second opening and closing beam 32, a fixed hinge seat 33, a movable hinge seat 34, and an electric support rod 35; the base 10 and the top cover 20 are provided with opening and closing guide rails 36 on opposite sides in the first direction. The lower end of the first opening and closing beam 31 is hinged to the movable hinge seat 34, which is slidably disposed on the opening and closing guide rail 36 of the base 10; the upper end of the first opening and closing beam 31 is hinged to the fixed hinge seat 33, which is fixed to the top cover 20. The lower end of the second opening and closing beam 32 is fixedly hinged to the fixed hinge seat 33, which is fixed to the base 10; the upper end of the second opening and closing beam 32 is hinged to the movable hinge seat 34, which is slidably disposed on the opening and closing guide rail 36 of the top cover 20. The first opening beam 31 and the second opening beam 32 are hinged at the middle; the electric strut 35 is used to rotate the first opening beam 31 or the second opening beam 32 around the fixed hinge seat 33 so that the roof cover 20 moves upward to unfold the roof tent, or moves downward to fold the roof tent.

[0023] In this invention, the first or second opening beam 31 is directly driven to rotate around the fixed hinge seat 33 by an electric strut 35. This, combined with the central hinge structure of the first and second opening beams 32 and the sliding engagement of the movable hinge seat 34 with the opening guide rail 36, allows the top cover 20 to move directly upwards to unfold and downwards to fold. The opening and closing components 30 are symmetrically arranged on both sides in the first direction, forming a dual-sided synchronous drive and support, avoiding structural tilting caused by unilateral force. The first and second opening beams 32 form a cross-hinged linkage mechanism, which, combined with the directional sliding of the movable hinge seat 34 along the opening guide rail 36, ensures precise and controllable movement trajectory of the top cover 20 during unfolding and folding, without jamming or deviation. After unfolding, the linkage mechanism forms a stable triangular support system, effectively distributing the load on the top cover 20 and the interior of the tent, improving the overall load-bearing capacity of the tent, and enabling it to withstand the impact of complex outdoor environments such as wind and rain, reducing the risk of structural deformation. This application utilizes a "vertical sliding" unfolding mechanism for the top cover 20, eliminating the need for rotation space and maximizing the vertical space between the base 10 and the top cover 20. This results in a more organized and spacious interior, enhancing user comfort. Furthermore, the rectangular base 10 and top cover 20 are highly adaptable, allowing for flexible design based on vehicle roof dimensions and accommodating various car models, thus offering wider versatility. Additionally, when the roof tent is folded, the top cover fits flat against the base. The overall thickness of the roof tent is approximately 10 centimeters, resulting in low wind resistance and reduced wind noise during driving. Its lighter weight also minimizes the upward shift of the center of gravity.

[0024] In this embodiment, an external support assembly 40 is also included; an external support assembly 40 is respectively provided on the opposite sides of the base 10 and the top cover 20 in the second direction; the second direction is perpendicular to the first direction; when the top cover 20 moves upward to unfold the roof tent, the external support assembly 40 is used to support the top cover 20 on the opposite sides of the base 10 in the second direction. Enhanced anti-tipping and wind resistance: The opening and closing assembly 30 in the first direction mainly undertakes the lifting drive and longitudinal support of the top cover 20, while the second direction (perpendicular to the first direction) is a weak point in the structure, easily swaying laterally or overturning under outdoor wind force. The external support assembly 40, located on the opposite sides of the second direction, fills the support gap in the second direction, making the tent form a two-way three-dimensional support structure of "longitudinal + transverse", greatly improving the overall anti-lateral displacement and anti-tipping performance. Even in complex outdoor environments such as strong winds and bumps, the structure can remain stable, ensuring user safety.

[0025] Specifically, the external support assembly 40 includes a central movable joint 41, an upper external support rod 42, and a lower external support rod 43. The upper external support rod 42 and the lower external support rod 43 are respectively hinged to both ends of the central movable joint 41. The upper end of the upper external support rod 42 is hinged to the top cover 20, and the lower end of the lower external support rod 43 is hinged to the base 10. The upper external support rod 42 and the lower external support rod 43 can rotate around the central movable joint 41. The hinged structure of the central movable joint 41 allows the included angle of the upper and lower external support rods 43 to flexibly change with the unfolded height of the top cover 20. Whether the top cover 20 is in a semi-unfolded or fully unfolded state, the external support assembly 40 can always maintain an effective supporting posture, providing stable support for the top cover 20. Compared with a fixed-length support structure, it has a wider range of adaptability and can meet the user's needs for different internal space heights.

[0026] In this embodiment, when the roof cover 20 moves upward to unfold the roof tent, the upper outer support rod 42 and the lower outer support rod 43 overlap vertically or partially overlap. This vertically overlapping support rod structure concentrates the force on the upper and lower outer support rods 43 vertically, forming a synergistic load-bearing system. Compared to dispersed lateral supports, the vertically overlapping structure has stronger resistance to compression and bending, and can more effectively resist loads above the roof cover 20. In this embodiment, the central movable joint 41 extends along the second direction, connecting two sets of upper outer struts 42 and lower outer struts 43 at its head and tail ends, respectively. This extension of the central movable joint 41 along the second direction allows for the connection of two sets of upper and lower outer struts 43 at its head and tail ends, forming an integrated support frame for the outer support assembly 40 on the second direction side, rather than independent, dispersed struts. The rigidity of this integrated frame structure is significantly higher than that of independent struts, effectively preventing deformation caused by uneven stress on individual struts and improving the overall stability of the second-direction support.

[0027] In this embodiment, an upper support plate 44 is arranged between the central movable joint 41 and the upper outer support rods 42 on both sides; a lower support plate 45 is arranged between the central movable joint 41 and the lower support rods on both sides. The upper support plate 44 connects the central movable joint 41 and the upper outer support rods 42 on both sides, and the lower support plate 45 connects the central movable joint 41 and the lower outer support rods 43 on both sides. Through the surface contact action of the support plates, the concentrated load of the support rods is distributed to a larger contact area, avoiding damage caused by excessive local stress at the connection between the support rods and the joint, and further improving the structural stability and service life of the outer support assembly 40.

[0028] Preferably, the upper support plate 44 is a glass plate or a transparent plastic plate; or, the upper support plate 44 has a movable side skylight 51. When the support plate is made of glass or a transparent plastic plate, its light transmittance can be used to provide natural lighting to the inside of the tent, reducing the reliance on artificial lighting during the day, making the inside of the tent brighter and more transparent, and improving the user's living experience; when the support plate has a movable side skylight 51, the ventilation volume can be flexibly adjusted as needed.

[0029] In this embodiment, the first opening and closing beam 31 and the second opening and closing beam 32 are composed of parallel steel beams and connecting beams welded between the steel beams; the bottom end of the electric support rod 35 is hinged to the fixed hinge seat 33 of the base 10, and the top end is hinged to the first opening and closing beam 31. The structure of "parallel steel beams + welded connecting beams" utilizes the high strength and rigidity of the steel beams, effectively improving the load-bearing capacity of the opening and closing beams. The connecting beams form an integrated structure with the parallel steel beams, avoiding bending deformation caused by uneven stress on individual steel beams. Furthermore, the welded connection method ensures strong structural stability during long-term repeated opening and closing operations, preventing loosening, breakage, and other malfunctions.

[0030] In this embodiment, a side tent 50 is provided between the outer periphery of the top cover 20 and the outer periphery of the base 10, and the side tent 50 is provided with an openable side skylight 51. The side tent 50 connects the outer periphery of the top cover 20 and the base 10 to form a complete enclosed space, which can effectively block outdoor wind, rain, dust, mosquitoes and other elements from entering the tent, providing users with a clean and comfortable camping environment; the openable side skylight 51 on the side tent 50 further enriches the ventilation and lighting channels of the tent, and can form convection ventilation in conjunction with the upper skylight 21 of the top cover 20, which can quickly improve the internal air quality.

[0031] In this embodiment, the top cover 20 is provided with an openable skylight 21. The skylight 21 provides the tent top with lighting and ventilation functions. During the day, opening the skylight 21 can bring in sufficient natural light, making the interior brighter and more transparent. At the same time, the top ventilation can create a "top out, bottom in" convection airflow, quickly expelling hot air and humid gases from the interior, improving the internal air quality, which is especially suitable for camping in hot and humid environments in summer.

[0032] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
