Description

Technical Field

[0001] This invention relates to the field of tent technology, and more specifically to a folding tent. Background Technology

[0002] With societal progress and improved living standards, cars have become commonplace in households, and self-driving camping and wilderness travel are increasingly becoming popular leisure travel options. Traditional ground tents, pitched directly on the ground, are easily susceptible to dampness, insect infestations, and ground debris and puddles, which can negatively impact camping comfort. Rooftop tents, installed on the roof of a vehicle, offer protection from damp ground and wildlife, are quick to set up, and provide a better living experience, making them a popular choice among self-driving enthusiasts.

[0003] Currently used rooftop tents mostly adopt the form of a folding rooftop tent disclosed in patent CN215485086U, which mainly includes a folding base plate, a support mechanism, and a climbing mechanism. The folding base plate is a split structure with the first and second aluminum honeycomb panels hinged together, and the aluminum honeycomb panels ensure the strength of the base plate. The support mechanism consists of stainless steel hinges, aluminum tube brackets, and a tent fabric. The tent fabric is opened by the aluminum tube brackets, and the tent fabric can be disassembled and replaced by soft sliding columns and cylindrical sliding tracks on the base plate. The climbing mechanism is located on the bottom surface of the base plate and has an independent climbing ladder and a spring pin type quick-release assembly, which supports quick assembly and disassembly of the climbing ladder. The tent is locked to the crossbar of the car roof rack by the bottom fixing component to achieve roof mounting.

[0004] However, in practical applications, the aforementioned rooftop tents are complicated to set up and take down, requiring a certain level of user proficiency. In outdoor camping scenarios, the setup and disassembly are time-consuming. During folding and storage, the tent fabric, being flexible, lacks a dedicated folding guide structure, failing to constrain the folding direction. This causes the tent fabric to easily fold outwards and bulge, increasing both storage volume and operational difficulty. Furthermore, the included ladder is a fixed, integrated structure that cannot be folded or retracted. Its overall length and volume are considerable. Even though the ladder can be detached from the tent using quick-release components, it still occupies significant storage space, making storage and carrying inconvenient. Overall, the rooftop tent offers poor usability. Summary of the Invention

[0058] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] In the description of this invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not 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 the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0060] like Figures 1-34 As shown, the present invention provides a folding tent, including a tent flip cover 104, a tent support base 105, a tent fabric 201, a support frame 202, and a flip drive assembly.

[0061] The flip drive assembly is used to drive the tent flip cover 104 to flip relative to the tent support base 105. The support frame 202 is assembled on the tent flip cover 104 and / or the tent support base 105. The tent fabric 201 is connected to the tent flip cover 104 and the tent support base 105 respectively. The support frame 202 supports the tent fabric 201 to form the internal activity space of the tent.

[0062] In the above technical solution, the flip drive component can drive the tent flip cover 104 to complete the flip action relative to the tent support base 105. The flip torque is transmitted through the upper connecting rod 102 and the lower connecting rod 103 to realize the automatic unfolding and folding of the tent. The operation is simple, eliminating the need for manual opening and closing and reducing the time spent on opening and closing the tent. The support frame 202 is assembled on the tent flip cover 104 and / or the tent support base 105 and supports the tent fabric 201, thereby constructing the internal activity space of the tent and improving the overall convenience of the tent.

[0063] Furthermore, the folding tent also includes a base 101, a tent flip cover 104 and a tent support base 105 respectively disposed on both sides of the base 101 and rotatably connected to the base 101; the flip drive assembly includes a drive component, an upper connecting rod 102 and a lower connecting rod 103, the drive component is located between the tent flip cover 104 and the tent support base 105, one end of the upper connecting rod 102 is rotatably connected to the power output end of the drive component, and the other end is rotatably connected to the tent flip cover 104, one end of the lower connecting rod 103 is rotatably connected to the power output end of the drive component, and the other end is rotatably connected to the tent support base 105.

[0064] In the above technical solution, the power output end of the drive component simultaneously links the upper connecting rod 102 and the lower connecting rod 103. The upper connecting rod 102 and the lower connecting rod 103 are respectively connected to the tent flip cover 104 and the tent support base 105, thereby completing the flip opening and closing action of the tent.

[0065] Specifically, flip drive components are provided at both ends of the base 101; the two sets of flip drive components operate synchronously, with the drive component driving its power output end to perform linear reciprocating motion, causing the upper connecting rod 102 and the lower connecting rod 103 to swing synchronously; the tent support base 105 is fixed to the vehicle body and remains stationary, thereby driving the tent flip cover 104 to flip outward relative to the tent support base 105 and open. In the fully opened state, the tent flip cover 104 and the tent support base 105 are in a 180° flattened posture; when performing the folding operation, the power output end of the drive component is reversed and reset, causing the upper connecting rod 102 and the lower connecting rod 103 to swing back, pulling the tent flip cover 104 to rotate, and finally making the tent flip cover 104 and the tent support base 105 stacked face to face, completing the folding and folding of the tent.

[0066] The above solution relies on the upper connecting rod 102 and the lower connecting rod 103 to transmit the flipping torque. The load of the tent flipping cover 104 is shared by the upper connecting rod 102 and the lower connecting rod 103, and the load is indirectly transmitted to the drive components. The flipping drive components at both ends output power synchronously, reducing the force deviation during the flipping of the cover. Compared with the structure of direct gear drive, this solution can reduce the impact on the transmission meshing parts and reduce the probability of damage. Compared with the flexible cable drive, the rigid connecting rod will not have problems such as loosening, swaying and slippage, and will have a reliable constraint on the tent flipping cover 104, making the flipping operation more stable.

[0067] It should be noted that the driving component is a linear driving component, and can be an electric strut, cylinder, hydraulic cylinder, linear module, or lead screw and nut pair, etc., which can output linear reciprocating motion.

[0068] Furthermore, an upper plate 106 and a lower plate 107 are rotatably connected to both sides of the base 101. The upper plate 106 is fixedly connected to the tent flip cover 104, and the lower plate 107 is fixedly connected to the tent support base 105. The upper plate 106 and the lower plate 107 serve as transitional connectors 317 between the base 101 and the tent body, which can distribute the load brought by the tent body. At the same time, the base 101, as an intermediate base, connects the flip drive components on both sides into one, which can play the role of installation benchmark and limit constraint for the two sets of flip drive components, assist in the linkage of the flip drive components on both sides, further improve the consistency of the action of the two sides of the mechanism, effectively suppress the problems of asynchronous operation, tilting and jamming on both sides during the opening and closing of the tent flip cover 104, and improve the anti-bump performance of the entire mechanism.

[0069] It should be noted that both the upper plate 106 and the lower plate 107 have shaft holes, with an opening on one side of each shaft hole. The base 101 has outwardly protruding rotating shafts on both sides, with the openings of the shaft holes facing the connection point between the rotating shaft and the base 101. The arc segment corresponding to the opening is a minor arc (central angle less than 180°), allowing the shaft holes and rotating shafts to rotate and engage. During assembly, the shaft holes and rotating shafts are slid in side-by-side. The arc encircling the rotating shaft is a major arc, providing a wider coverage area and effectively constraining radial displacement, ensuring a stable and durable rotating connection.

[0070] Furthermore, the driving component includes: a support 108, fixedly mounted on the base 101, the support 108 having a clearance groove 109 for the upper connecting rod 102 and the lower connecting rod 103 to swing and avoid each other; a motor 110, fixedly mounted on the support 108; a lead screw 111, one end of which is connected to the output shaft of the motor 110; and a slider 113, threadedly mounted on the lead screw 111, with a pin mounted on the slider 113, the upper connecting rod 102 and the lower connecting rod 103 being rotatably connected to the pin, and the slider 113 also having a transmission limiting part.

[0071] In the above technical solution, the slider 113 can be directly threaded onto the lead screw 111, or it can be equipped with a nut 112 that is threaded onto the lead screw 111. The slider 113 is fixed to the outer wall of the nut 112, and a pin is mounted on the slider 113. The upper connecting rod 102 and the lower connecting rod 103 are rotatably connected to the pin. The motor 110 drives the lead screw 111 to rotate via a coupling. The rotational motion of the motor 110 is converted into the linear reciprocating motion of the slider 113 by the lead screw and nut pair. The slider 113 synchronously drives the upper connecting rod 102 and the lower connecting rod 103 to swing and output the flipping power through the pin. The support 108 is provided with a clearance groove 109 to provide movement space for the connecting rod to swing and avoid motion interference.

[0072] When the slider 113 can be directly threaded onto the lead screw 111, the transmission limiting part is a support 108 (e.g., rectangular) that fits the shape of the slider 113. The support 108 restricts the rotation of the slider 113, allowing it to move only along the lead screw 111. Alternatively, the transmission limiting part can be a limiting rod 114 fixed inside the support 108 with its axis parallel to the axis of the lead screw 111. The slider 113 has a limiting hole that slides with the limiting rod 114. The support 108 has a limiting rod 114 parallel to the lead screw 111 inside. The slider 113 slides with the limiting hole, circumferentially limiting the slider 113 and preventing the nut 112 from rotating circumferentially with the lead screw 111, ensuring that the slider 113 moves only linearly along the lead screw 111. The transmission limiting part can also be set in both of the above ways simultaneously, making the transmission more stable. This screw and nut pair transmission system features high transmission rigidity and excellent self-locking performance. After power is cut off, the tent canopy can be maintained in position by relying on the self-locking effect of the screw and nut pair, eliminating the need for additional locking accessories. It is suitable for the limited installation space of vehicle-mounted tents.

[0073] It should be noted that the support 108 is a rectangular shell structure with several weight-reducing holes to reduce its overall weight. The support 108 has a cover on its side, which allows for easy assembly and maintenance of the internal transmission components. The motor 110 is preferably a DC geared motor. The structure is also equipped with a controller, which collects the operating speed and position feedback signals of the two motors 110 in real time and performs signal deviation compensation through algorithm calculation to ensure that the two motors 110 operate in a unified manner and realize the synchronous opening and closing of the two sets of flip drive components.

[0074] Furthermore, the support 108 is provided with a lower seat 115 and a middle seat 116 inside. The two ends of the limiting rod 114 are fixedly connected to the lower seat 115 and the middle seat 116 respectively. The lead screw 111 is rotatably supported on the lower seat 115 and the middle seat 116 through the bushing 117 respectively. The support 108 has a lower seat 115 and a middle seat 116 inside, which serve as the mounting base for the lead screw 111 and the limiting rod 114. The two ends of the limiting rod 114 are fixed to the lower seat 115 and the middle seat 116 respectively to achieve end fixation, thereby improving the overall rigidity of the limiting rod 114. The lead screw 111 is rotatably supported by the lower seat 115 and the middle seat 116 with the help of the bushing 117, thereby achieving two-point radial support for the lead screw 111, constraining the radial runout of the lead screw 111, reducing the shaking and eccentricity of the lead screw 111 during high-speed rotation, reducing the wear between the lead screw 111 and the nut 112, improving the smoothness of the lead screw and nut pair transmission, and extending the service life of the lead screw and nut pair.

[0075] Furthermore, it also includes a spring 118, which is sleeved on the outside of the lead screw 111. One end of the spring 118 is fixedly connected to the middle seat 116, and the other end of the spring 118 is positioned towards the slider 113. During the process of the slider 113 moving towards the middle seat 116 and the tent closing, the slider 113 gradually compresses the spring 118. The spring 118 can absorb the impact energy of the slider 113 reaching the end of its stroke, playing a buffering role at the end, effectively reducing the vibration and operating noise of the whole machine. During the opening and flipping stage of the tent, the compressed spring 118 rebounds and releases its elastic force, which can assist in pushing the slider 113 to move, providing assistance for the opening of the tent flipping cover 104, speeding up the opening speed, avoiding the linkage transmission from jamming, and improving the smoothness and reliability of the entire transmission mechanism. It should be noted that the spring 118 can be a cylindrical helical compression spring, a tower spring, or other elastic components. Any elastic component that can achieve axial compression energy storage, rebound force release, and continuous axial preload is suitable for this structure.

[0076] Furthermore, a ring 119 is fixedly mounted on the end of the spring 118 facing the slider 113. The ring 119 is fitted onto the outside of the lead screw 111, and the end face of the ring 119 is positioned opposite to the slider 113. The ring 119 serves as an intermediate force transmission component between the spring 118 and the slider 113, preventing the spring 118 from directly contacting the slider 113 and preventing the end of the spring 118 from scratching or bumping the slider 113, thus avoiding damage to the parts. The ring 119 increases the contact and bearing area of ​​the spring 118, allowing the elastic force of the spring 118 to be evenly applied to the end face of the slider 113, preventing local stress concentration and twisting of the spring 118, and ensuring the stable and reliable buffering and pre-tensioning effect of the spring 118.

[0077] Furthermore, it also includes an open position detection element 120 and a retractable position detection element 121, both of which are fixedly installed on the support 108. The detection ends of the open and retractable position detection elements 120 and 121 correspond to the positions of the slider 113. Based on the position feedback of the slider 113, it can be determined whether the tent flip cover 104 is in the fully open or fully retracted limit position, and a stop command is sent to the motor 110, realizing automated control of the mechanism's stroke without the need for manual visual judgment of the cover's opening and closing position. Both the open and retractable position detection elements 120 and 121 are electrically connected to the controller. After the detection element collects the signal of the slider 113 being in position, it transmits the position electrical signal to the controller. After receiving the signal, the controller outputs a control command to promptly stop the motor 110. It should be noted that the open and retractable position detection elements 120 and 121 can be any type of position sensing device, such as a limit switch, a Hall sensor, or a photoelectric sensor.

[0078] Furthermore, the support 108 is equipped with two tensioning components 123, which are respectively connected to the tent flip-up cover 104 and the tent support base 105. When the tent is open and flattened, the tensioning components 123 can share the load borne by the upper connecting rod 102 and the lower connecting rod 103, reducing the long-term stress loss of the screw nut pair. It should be noted that the tensioning components 123 can be flexible tensioning components with tensile strength but no active telescopic function, such as soft steel wire, stainless steel wire rope, galvanized steel cable, aramid rope, polyester braided rope, or high-strength nylon webbing, and can be flexibly selected according to the usage environment and load-bearing capacity requirements. In this embodiment, the tensioning component 123 includes two sections of steel wire connected by a tensioner 124. The tension of the steel wire is adjusted by the tensioner 124 to adapt to actual usage requirements; the tensioner 124 is preferably a turnbuckle tensioner.

[0079] Specifically, to improve the overall structural strength of the tent support base 105, a crossbeam 408 is fixedly arranged inside the tent support base 105, and a honeycomb panel is filled to form a composite reinforcement structure. With the synergistic effect of the crossbeam 408 and the honeycomb panel, the bending and deformation resistance of the tent support base 105 is improved, ensuring that it can stably bear the tent load during the lifting process.

[0080] Furthermore, the tent flip-top cover 104 is provided with at least two support members 122. When the tent flip-top cover 104 is fully unfolded, the support members 122 can provide auxiliary support for the tent flip-top cover 104, share the self-weight load of the tent flip-top cover 104 borne by the upper connecting rod 102 and the lower connecting rod 103 of the opening and closing structure, reduce the long-term working load of the connecting rod, pin, slider 113, and lead screw nut pair, and reduce fatigue wear of transmission components; when personnel are moving inside the tent, the support members 122 can share the additional load brought by the personnel, further protect the flip-top opening and closing structure, and improve the overall structural stability of the tent in the unfolded and used state.

[0081] It should be noted that the support component 122 includes a damping ball joint and a strut connected to the damping ball joint; the damping ball joint is fixedly installed on the tent flip cover 104. The damping ball joint allows the strut to swing in multiple angles, and the swinging process generates its own frictional damping torque. When the strut lands, it can adapt to slight ground inclinations and effectively suppress strut swaying and shaking, ensuring the stability of the tent in its unfolded state. When the tent is in its stowed state, the struts are close to the surface of the tent flip cover 104, preventing the struts from swaying and bumping during vehicle travel and thus reducing driving noise.

[0082] Furthermore, the tent 201 and / or the supporting frame 202 are equipped with elastic elements 203 for providing bending constraints on the tent 201 and guiding the tent 201 to fold inward. During the folding and retraction of the tent, the elastic elements 203 provide bending constraints on the tent 201 and guide the tent 201 to fold inward.

[0083] In the above technical solution, elastic elements 203 are installed on the tent fabric 201 and / or the support frame 202. When the tent is folded up, the elastic elements 203 provide bending constraints on the tent fabric 201 and guide the tent fabric 201 to fold inward. Relying on the deformation energy storage and reset energy release characteristics of the elastic elements 203, the irregular outward bulging of the tent fabric 201 is restricted, allowing the tent fabric 201 to fold up along with the support frame 202, making the tent storage more compact.

[0084] Furthermore, the elastic element 203 is a spring and is installed on the tent fabric 201. The spring is made of a material with elastic deformation capability, such as stainless steel, fiberglass, carbon fiber, high-toughness plastic, etc. When the tent is unfolded, the spring is in the open state and stores elastic potential energy. When the tent is folded up, the spring elastically resets, pushing the tent fabric 201 to fold inward and forming a bending constraint. The bending constraint means that the spring limits the tent fabric 201 to bend only along a preset route, preventing the tent fabric 201 from turning outward at will, and actively driving the tent fabric 201 to fold inward.

[0085] It should be noted that, in addition to springs, elastic elements 203 can also be made of other components with energy storage and reset functions, such as elastic ropes or torsion elastic elements, to achieve the same guiding effect. When elastic elements 203 are springs or elastic ropes, they can be directly installed on the tent fabric 201, or connected to the foldable support frame 202 at both ends, and the tent fabric 201 can be folded inward by driving the support frame 202 to bend. When elastic elements 203 are torsion elastic elements, they can be torsion springs, spiral torsion springs, or elastic torsion hinges, and can be installed at the folding hinge of the foldable support frame 202 or at the rotational connection position between the support frame 202 and the tent support base 105.

[0086] Furthermore, the tarpaulin 201 is provided with a receiving part for holding the spring. The spring is accommodated through the receiving part. Specifically, it can adopt various installation and fixing methods. A storage pocket can be sewn into the tarpaulin 201 as a receiving part, or an insertion opening can be opened in the double-layer tarpaulin sandwich and pressed to form a limiting groove that fits the shape of the spring. The spring can also be fixed by adhesive, or Velcro can be placed at the corresponding position of the tarpaulin 201 and the spring to achieve detachable assembly. Multiple installation methods are suitable for different tarpaulin materials, which not only ensures that the spring is reliably fixed and deforms smoothly, but also avoids the spring being exposed and scratching the tarpaulin 201 or the user.

[0087] Furthermore, the support frame 202 includes a top rod 204 and two folding rods 205. The two folding rods 205 are hinged to both ends of the top rod 204, and the ends of the folding rods 205 away from the top rod 204 are rotatably connected to the tent support base 105. During the tent folding process, the spring drives the tent fabric 201 to fold inward, pulling the folding rods 205 inward. The folding rods 205 cooperate with the tent fabric 201 to complete the folding action, realizing the folding of the tent fabric 201 and the support frame 202.

[0088] Furthermore, the folding rod 205 includes two hinged rods 206, the free ends of which are rotatably connected to the end of the top rod 204 and the tent support base 105, respectively. When the spring causes the tent fabric 201 to fold inward, the two rods 206 can rotate and bend relative to each other, adapting to the folding trajectory of the flexible curved surface of the tent fabric 201, reducing the resistance to frame folding, improving the folding flexibility of the support frame 202, and further reducing the overall storage volume after folding. In specific implementations, the number of rods 206 can be selected as needed, with adjacent rods 206 hinged together.

[0089] Furthermore, the folding rod 205 is connected to the tent support base 105 via a universal joint 207 or a ball joint. The universal joint 207 or the ball joint has multiple degrees of freedom. When the folding rod 205 swings and folds at multiple angles during the tent folding process, the universal joint 207 or the ball joint can compensate for the rotation angle deviation, release the interference of the rod movement, prevent the rod from jamming, and improve the smoothness of the folding operation.

[0090] Furthermore, with the folding rod 205 in its extended state, the springs are arranged in a crisscross pattern with the folding rod 205. When the tent fabric 201 is unfolded, the folding rod 205 is in its extended state, and the springs are in their open state, storing elastic potential energy. After the tent fabric 201 is relaxed, the springs elastically reset, pushing the tent fabric 201 inward and forming a bending constraint to prevent the tent fabric 201 from flipping outward at will. The crisscross arrangement optimizes the force transmission path; the force generated by the springs resetting can be transmitted to the folding rod 205, guiding the folding rod 205 to rotate inward synchronously with the tent fabric 201 and retract, improving the smoothness of retraction.

[0091] Furthermore, the folding tent also includes a ladder, which includes at least one ladder unit structure. The ladder unit structure includes an inner base 301, an outer sliding sleeve 302, and several foot pedals 303. The outer sliding sleeve 302 is slidably fitted on the outside of the inner base 301. The side wall of the inner base 301 is provided with guide limiting grooves 304 corresponding to each foot pedal 303. The outer sliding sleeve 302 is provided with drive grooves 305 corresponding to each foot pedal 303. One end of the foot pedal 303 passes through the drive groove 305 and the guide limiting groove 304 and is rotatably connected to the inner base 301. The outer sliding sleeve 302 slides relative to the inner base 301 and drives the foot pedal 303 to flip through the drive groove 305. When the foot pedal 303 unfolds outward, it abuts against the support part of the guide limiting groove 304.

[0092] In the above technical solution, the tent is installed on the roof of the vehicle, and the ladder facilitates personnel to go up and down the tent. When the ladder is needed, the outer sliding sleeve 302 slides downward relative to the inner base 301, and the drive groove 305 drives the foot pedal 303 to flip outward and unfold. After unfolding, the foot pedal 303 abuts against the support part of the guide limiting groove 304, and the support part bears the foot pedal 303 and the load of the human body stepping on it. After use, the outer sliding sleeve 302 slides upward relative to the inner base 301, and the drive groove 305 drives the foot pedal 303 to fold inward, reducing the space occupied by the ladder unit. During the flipping process of the foot pedal 303, the guide limiting groove 304 guides and constrains the movement of the foot pedal 303. Together with the support part supporting and limiting the foot pedal 303, it improves the structural stability and safety of use during footing operations. The overall structure is compact and easy to carry and transport.

[0093] It should be noted that, to ensure safety during staircase use, when only one staircase unit is installed, a fixing member 318 is fitted at the upper end of the inner base 301, and a step pad 319 is fitted at the lower end of the outer sliding sleeve 302. When multiple staircase units are installed, in the staircase units arranged in a straight line, a fixing member 318 is fitted at the upper end of the inner base 301 of the uppermost staircase unit, and a step pad 319 is fitted at the lower end of the outer sliding sleeve 302 of the lowermost staircase unit. During installation, the foot pedal 303 can be rotatably connected to the inner base 301 using locking studs and countersunk screws. Both the inner base 301 and the outer sliding sleeve 302 are hollow, reducing the overall weight of the staircase and facilitating the folding and installation of the foot pedal 303.

[0094] It should also be noted that this staircase is mainly used in the following two ways:

[0095] The first method involves using the fixing member 318 on the inner base 301 at the top in the unfolded state to complete the suspension and fixation, connecting the ladder to the roof tent or roof beam; when in use, pulling down the outer sliding sleeve 302 causes the foot pedal 303 to flip outward and unfold. The lower end of the outer sliding sleeve 302 can be in contact with the ground or in a suspended state; the foot pedal 303 abuts against the support to support the stepping load; if the lower end of the outer sliding sleeve 302 is in contact with the ground, the upper end of the drive groove 305 can contact or detach from the foot pedal 303; if the lower end of the outer sliding sleeve 302 is suspended, the upper end of the drive groove 305 contacts the foot pedal 303, thereby achieving the limiting constraint of the outer sliding sleeve 302;

[0096] The second method involves the outer sliding sleeve 302 sliding relative to the inner base 301, causing the foot pedal 303 to unfold outwards. The inner base 301 at the top is then pressed against the external support. The operator steps on the bottom foot pedal 303, alternating between both feet to complete the climbing operation.

[0097] When the foot pedal 303 is in the folded state, the end of the outer sliding sleeve 302 is close to or abuts against the fixing member 318 on the inner base 301.

[0098] Furthermore, a support block 306 is fixed to the lower end of the guide limiting groove 304, forming a support component. After the foot pedal 303 is deployed, the load acts on the support block 306, which can prevent the foot pedal 303 from directly rubbing against and impacting the inner base 301, reducing the wear of the inner base 301. The support block 306 is an independent component, which can be disassembled and replaced separately after wear and damage, without the need to replace the entire inner base 301, thus reducing maintenance costs. Of course, in specific implementations, the lower groove wall of the guide limiting groove 304 itself can be used as the support component.

[0099] Furthermore, each drive slot 305 corresponding to the outer sliding sleeve 302 is equipped with a drive block 307, and the drive block 307 has a clearance opening for the foot pedal 303 to rotate. The free end of the foot pedal 303 is equipped with a protective member 308. When the foot pedal 303 is rotated inward and retracted into place, the protective member 308 abuts against the drive block 307. When the foot pedal 303 is rotated inward and retracted into place, the protective member 308 and the drive block 307 abut against each other. The protective member 308 can be made of rubber, which can seal the assembly gaps and play a role in dustproof and waterproof protection. The drive block 307 can be made of plastic to further reduce the weight of the component.

[0100] Furthermore, the drive block 307 has an insertion groove 309 for the protective component 308 to be flipped and inserted. After being stored, the protective component 308 is accommodated inside the insertion groove 309 and will not protrude outward, making the outer contour of the stair unit structure more regular. The insertion groove 309 covers the protective component 308, which can reduce the entry of external rainwater and dust into the interior through the mating gap, improve the dustproof and waterproof capabilities of the stair unit structure, and also limit the excessive inward flipping of the foot pedal 303, playing an auxiliary limiting role in the storage position of the foot pedal 303. The drive block 307 is connected to the outer sliding sleeve 302 by screws.

[0101] Furthermore, a buffer block 310 is fixed to the inner wall of the outer sliding sleeve 302, and the buffer block 310 is sandwiched between the outer sliding sleeve 302 and the inner base 301. The buffer block 310 can fill the assembly gap between the inner base 301 and the outer sliding sleeve 302, suppressing radial shaking of the outer sliding sleeve 302 relative to the inner base 301; during the reciprocating sliding operation of the outer sliding sleeve 302, the buffer block 310 remains between the two, reducing direct contact friction and impact, effectively reducing shaking noise. The buffer block 310 can be made of rubber, which has good elasticity and wear resistance. Specifically, the buffer block 310 and the drive block 307 can be integrally molded and made of plastic material, with strong structural integrity, fewer assembly steps, and can simultaneously achieve wear resistance, noise reduction, and lightweight effects.

[0102] Furthermore, a hand guard 311 is installed on the outer sliding sleeve 302. When operating the outer sliding sleeve 302 or performing climbing operations, personnel can hold the hand guard 311 for leverage; the openings on the hand guard 311 allow fingers to be inserted for gripping, improving the anti-slip effect when gripping, making it easier for users to push and pull the outer sliding sleeve 302 to complete the unfolding or retracting of the foot pedal 303, improving the operating feel and safety.

[0103] Furthermore, the staircase comprises multiple individual staircase structures, with the inner base 301 of adjacent individual staircase structures rotatably connected end-to-end. In the folded state, the multiple individual staircase structures can rotate relative to each other to form the staircase body; in the unfolded state, the multiple individual staircase structures can rotate relative to each other to form a straight line arrangement. Multiple individual staircase structures are configured according to the actual climbing height requirements. The inner base 301 of adjacent individual staircase structures are rotatably connected end-to-end, and a hinge structure such as a three-fold hinge can be used. This ensures that the included angle between adjacent individual staircase structures approaches 0° when folded, and that all individual staircase structures are in a straight line when unfolded. In the folded state, the multiple individual staircases can rotate to form a straight line arrangement, significantly reducing the overall storage volume and facilitating transportation and storage. In use, they can be rotated and unfolded to form a complete staircase that meets the climbing height requirements.

[0104] It should be noted that a reinforcing member is fixed inside the outer sliding sleeve 302. During the sliding process of the outer sliding sleeve 302 relative to the inner base 301, the reinforcing member moves synchronously with the outer sliding sleeve 302. When the outer sliding sleeve 302 slides into place and the foot pedal 303 unfolds outward, the reinforcing member is precisely aligned with the connection part of the adjacent inner base 301. This provides structural reinforcement to the hinge connection of the adjacent inner base 301, improves the overall strength of the combined structure of multiple staircase units, and prevents the connection part of the adjacent inner base 301 from bending and deforming when the staircase is subjected to stepping load, thus ensuring the structural stability during use.

[0105] Specifically, when the inner bases 301 of adjacent staircase units are connected to each other, the connection structure includes a first hinge assembly, a second hinge assembly, and a connecting plate 320. The first hinge assembly includes a first convex hinge 321 and a first concave hinge 322 that are hinged to each other, and the second hinge assembly includes a second convex hinge 323 and a second concave hinge 324 that are hinged to each other. The first convex hinge 321 and the second concave hinge 324 are respectively fixed to two adjacent inner bases 301, and the first concave hinge 322 and the second convex hinge 323 are respectively fixedly connected to the connecting plate 320. Relying on the cooperation of the first hinge assembly, the second hinge assembly, and the connecting plate 320, when the adjacent inner bases 301 are in a straight unfolded state, the first hinge assembly, the second hinge assembly, and the connecting plate 320 are arranged on the same side; when the adjacent inner bases 301 are rotated to a side-by-side stowed state, the first hinge assembly and the second hinge assembly are respectively located on both sides of the connecting plate 320 and arranged correspondingly to each other.

[0106] Furthermore, a cap 312 is fitted to the end of the staircase body. The cap 312, fitted to the end of the folded staircase body, restrains and organizes the end of the staircase body, preventing displacement and scattering of individual staircase components. The cap 312 has openings to facilitate the drainage of water that has entered the staircase body, reducing internal water accumulation. The cap 312 can be made of rubber or plastic and can be directly fitted onto the end of the staircase body, providing a certain degree of cushioning and protection. Of course, in practice, the cap 312 can also be made of other materials, and threaded holes can be pre-set on the staircase body, using bolts to lock the cap 312 to the end of the staircase body. Multiple assembly methods can adapt to different processing and usage requirements. A cap 312 is installed at one end of the folded staircase body, and a fastener 318 and a step pad 319 are located at the other end of the staircase body to avoid interference with the cap 312. Therefore, the single staircase structure can be used alone. When multiple staircases are used, it is preferable that the number is even, such as two or four.

[0107] Furthermore, the staircase also includes a storage bracket 313; the storage bracket 313 has a storage slot into which the staircase body can be inserted, and limiting members 314 for limiting the staircase body are provided on both sides of the storage slot, and a locking member 315 is provided at the storage opening of the storage slot. After the staircase is folded to form the staircase body, it can be placed entirely into the storage slot of the storage bracket 313; the limiting members 314 on both sides of the storage slot can be corner brackets or L-shaped members, which constrain the staircase body from the side, limiting the lateral displacement of the staircase body and the displacement away from the storage opening; the locking member 315 at the storage opening can lock the staircase body in the storage slot to prevent accidental dislodgement; the storage bracket 313 can be made of bent parts welded together, and a support 108 is fixed on the storage bracket 313, and the storage bracket 313 can be fixed in the target installation position through the mounting holes on the support 108.

[0108] Specifically, the locking element 315 at the storage opening adopts a combination structure of pressure plate 325, buckle 326, and bracket 327. Pressure plate 325 is rotatably mounted on one side of the storage opening of storage bracket 313. Buckle 326 is fixedly installed on the free end of pressure plate 325, and bracket 327 is fixedly installed on the other side of storage opening of storage bracket 313. When the ladder body is completely inserted into the storage slot, rotating pressure plate 325 causes buckle 326 and bracket 327 to engage with each other, thereby locking the ladder body in the storage slot and preventing the ladder body from accidentally coming out of the storage opening. When unlocking, buckle 326 is disengaged from bracket 327, and rotating pressure plate 325 can open the storage opening for easy removal of the ladder body.

[0109] Specifically, the pressure plate 325 bends and protrudes towards the storage opening on one side to form a pressing and limiting part 328. When the buckle 326 engages with the card seat 327, the protruding part of the pressure plate 325 presses tightly against the outside of the stair body, further pressing and limiting the stair body in the storage slot, restricting the stair body from shaking or moving in the storage slot, making the storage and locking state more stable and reliable.

[0110] Furthermore, the storage bracket 313 is fixed with a suspension member 316, and the stair body is fixed with a connecting member 317, which is assembled onto the suspension member 316. The suspension member 316 on the storage bracket 313 is rotatably connected to the connecting member 317 on the stair body, realizing the assembly between the stair body and the storage bracket 313, making them an assembled whole; specifically, the connecting member 317 is fixedly set on the fixing member 318 of the inner base 301. To facilitate assembly and swing guidance, the suspension member 316 is made of a bent part, with a bending angle set to 100°-150°, preferably 120°; one end of the bent part is fixedly connected to the storage bracket 313, and the other end is rotatably connected to the connecting member 317. The bending configuration adapts to the movement angle requirements of the stair body's swing and storage, ensuring smooth and interference-free swing and storage process of the stair body.

[0111] Furthermore, the suspension component 316 is a bent component, and its bending angle can limit the tilt angle of the staircase. The suspension component 316 is provided with a guide rail 329, which is L-shaped. A pin or bolt passes through the guide rail 329 to connect the suspension component 316 and the connector 317, realizing the hinged assembly between the suspension component 316 and the connector 317. The pin or bolt can slide inside the guide rail 329 and can also rotate relative to it. During the storage operation, the staircase body is first moved towards the storage bracket 313, which drives the pin or bolt to move to the end of the guide rail 329 near the storage bracket 313. Then, the staircase body is rotated to make it turn into the storage slot. Then, the staircase body is pushed, and the pin or bolt slides along the guide rail 329 towards the limiting component 314 until the staircase body abuts against the limiting component 314 to complete the positioning. Finally, the storage opening is sealed by the locking component 315. The entire storage process relies on guide rail 329 to constrain the movement trajectory of the stair body, guiding the stair body to accurately fall into the storage slot and be positioned, ensuring stable and reliable assembly and storage.

[0112] Taking two interconnected staircase units as an example, their unfolding and folding processes are as follows: Unfolding: In the initial state, the two staircase units are placed side-by-side to form the staircase body. One end of the staircase body is hinged to the suspension member 316, and the entire structure is contained within the storage slot of the storage bracket 313, locked in place by the locking member 315 at the storage opening. In use, first release the locking member 315, then pull the staircase body outwards, allowing it to slide out of the storage slot. The inner body is moved out as a whole; then the two individual stair structures are rotated, changing from a side-by-side, fitted storage state to a straight-line, unfolded state, combining to form a complete extended staircase; subsequently, the outer sliding sleeve 302 slides downward relative to the inner base 301. During the movement, the outer sliding sleeve 302, with the cooperation of the drive groove 305 and the guide limiting groove 304, drives the foot pedal 303 to flip outward and unfold; after the foot pedal 303 is fully unfolded, it abuts against the support block 306 of the guide limiting groove 304, and is supported by the support block 306. The foot pedal 303 is supported by the stepping load, ensuring reliable support. After the outer sliding sleeve 302 slides into place, it aligns with and covers the hinged connection of the adjacent inner base 301, providing structural reinforcement to the hinged position to prevent bending deformation during climbing. The operator can then step on the foot pedal 303 to perform climbing operations. Folding and storage process: After use, the operator leaves the ladder and slides the outer sliding sleeve 302 upwards relative to the inner base 301, driven by the drive groove 305. Foot pedal 303 flips inward and folds back, completing the folding and resetting of foot pedal 303; then the two step ladder units that were unfolded in a straight line are rotated in the opposite direction to return to a parallel and close-fitting state, and are folded back into the step ladder body; then the step ladder body is moved and rotated so that the step ladder body is turned into the storage slot, and the step ladder body is pushed until the step ladder body abuts against the limiting member 314. Finally, the locking member 315 is closed to lock the storage opening, constraining and fixing the step ladder body in the storage slot, completing the entire folding and storage process.

[0113] It should be noted that the storage bracket 313 is fixedly installed on one side of the tent body, specifically below one end of the tent support base 105 and near the edge. When in use, the ladder body is removed; after use, it is placed inside the storage bracket 313. The ladder body is hinged to the storage bracket 313 via the suspension member 316. After unfolding the ladder, operators can climb by stepping on the foot pedals 303, facilitating entry and exit from the rooftop tent. When not in use, the ladder body can be folded and locked in the storage slot of the storage bracket 313, without taking up additional space inside the vehicle, resulting in a compact overall arrangement.

[0114] Furthermore, the folding tent also includes a claw structure 4, which includes a fixed claw 401, a movable claw 402, and a drive assembly; the drive assembly is connected to the movable claw 402 and drives the movable claw 402 to move closer to or further away from the fixed claw 401; the fixed claw 401 and the movable claw 402 cooperate to form a locking part for holding the roof rack 403.

[0115] In the above technical solution, the drive component forms a transmission connection with the movable claw 402, which can drive the movable claw 402 to move closer to or further away from the fixed claw 401. When the movable claw 402 moves closer to the fixed claw 401, the fixed claw 401 and the movable claw 402 cooperate to form a locking part that grips the roof rack 403. By changing the size of the clamping opening of the locking part by the relative displacement of the two, it can not only achieve clamping and locking of the roof rack 403 and ensure the reliability of the force when the claw structure 4 clamps and fixes, but also drive the movable claw 402 away from the fixed claw 401 to increase the opening of the locking part, so as to realize the quick disassembly and separation of the claw and the roof rack 403. The whole system relies on the power output of the drive component to complete the clamping and releasing action. It can be adapted to roof rack 403 rods of different thicknesses and specifications. The structure is simple and easy to use.

[0116] Furthermore, the drive assembly includes a drive member 404 and an anti-rotation limiting structure for limiting the rotation of the movable claw 402. The fixed claw 401 is rotatably connected to the drive member 404. The drive member 404 is provided with a threaded section, and the movable claw 402 is provided with a threaded hole that is threadedly connected to the threaded section of the drive member 404.

[0117] In the above technical solution, the driving component 404 can be a screw or a threaded shaft. Relying on the threaded section of the driving component 404 and the threaded hole of the movable claw 402, the threaded pair has a self-locking function. Rotating the driving component 404 can be converted into linear displacement of the movable claw 402, thereby adjusting the clamping opening size of the engaging part. This can adapt to roof racks 403 of different shapes and sizes. At the same time, the anti-rotation limiting structure restricts the movable claw 402 from rotating, ensuring that the movable claw 402 only performs linear translation and avoids rotating with the driving component 404, thus ensuring stable and reliable clamping action.

[0118] Furthermore, the movable jaw 402 includes a jaw body 405 and a jaw shaft 406 rotatably connected to the jaw body 405. A threaded hole is provided through the jaw shaft 406, and a clearance hole is provided through the jaw body 405 corresponding to the threaded hole for the drive component 404 to pass through. The upper end of the jaw body 405 extends laterally outward to form an arc-shaped pressing platform 407. The arc-shaped pressing platform 407 can overlap the crossbeam 408. The upper end of the arc-shaped pressing platform 407 is provided with an arc-shaped surface 409. The upper end of the fixed jaw 401 is provided with a guide slope 410. The arc-shaped surface 409 and the guide slope 410 are arranged opposite to each other to form a wedge-shaped pressing structure.

[0119] In the above technical solution, the movable claw 402 is designed as a split structure. The driving component 404 passes through the clearance hole of the claw body 405 and is threadedly engaged with the threaded hole on the claw shaft 406. When clamping a large-sized roof rack 403, the driving component 404 drives the claw body 405 to move and contact the roof rack 403. After the driving component 404 continues to rotate, the claw body 405 can rotate in the forward direction around the claw shaft 406, so that the arc-shaped clamping table 407 presses against the crossbeam 408. When clamping a small-sized roof rack 403... After the driving component 404 drives the claw body 405 to move and contact the roof rack 403, the driving component 404 continues to rotate, and the claw body 405 can rotate in the opposite direction around the claw axis 406, which also causes the arc-shaped clamping table 407 to clamp the crossbeam 408. Relying on the adaptive rotation of the claw body 405 around the claw axis 406, the arc-shaped clamping table 407 can always reliably clamp the crossbeam 408, which can be compatible with the clamping conditions of roof racks 403 of different sizes, and realize the connection between the claw structure 4 and the crossbeam 408 and the roof rack 403 at the same time.

[0120] Furthermore, the claw structure 4 is assembled on the crossbeam 408; the upper end of the fixed claw 401 extends laterally to form a fixed pressing platform 411, which can overlap the crossbeam 408; both the fixed claw 401 and the movable claw 402 are provided with sliding parts 412, and the anti-rotation limiting structure includes a limiting groove 413 opened in the crossbeam 408, with the sliding part 412 slidingly engaging with the limiting groove 413.

[0121] In the above technical solution, the fixed claw 401 is initially supported by the fixed clamping table 411, which overlaps the crossbeam 408. The anti-rotation limiting structure utilizes the limiting groove 413 on the crossbeam 408 to slide with the sliding part 412 of the claw. During the displacement of the movable claw 402 driven by the rotation drive 404, the sliding part 412 is constrained and guided by the limiting groove 413, limiting the claw from deflection. Of course, in specific implementation, the fixed claw 401 can also be directly fixed to the lower end of the crossbeam 408. The crossbeam 408 is fixedly installed on the tent support base 105.

[0122] Furthermore, the fixed claw 401 has a clamping portion 414 for clamping the crossbeam 408. The clamping portion 414 is U-shaped or C-shaped, and the clamping portion 414 has an opening corresponding to the claw body 405 for the roof rack 403 to enter. The clamping portion 414 can clamp and limit the roof rack 403. The clamping portion 414 and the claw body 405 of the movable claw 402 cooperate with each other to form a clamping portion, realizing a wrap-around clamping constraint on the roof rack 403, increasing the contact limiting range, dispersing the force, making the connection force between the claw structure 4 and the roof rack 403 more balanced, and improving the overall structural stability of the connection.

[0123] Furthermore, the folding tent also includes a lifting structure 5, which includes a winding assembly and at least three lifting ropes 501; one end of each lifting rope 501 is connected to the winding assembly, and the free end of the lifting rope 501 is used for detachable connection to the tent support base 105; the winding assembly is used for winding or releasing the lifting ropes 501.

[0124] In the above technical solution, the tent is detachably mounted on the roof rack 403 using the claw structure 4. When the tent needs to be disassembled, the claw structure 4 is separated from the roof rack 403, the free end of the lifting rope 501 is connected to the tent support base 105, and the winding assembly drives the lifting rope 501 to wind up, lifting the tent from the roof to remove it from the vehicle. After disassembly, the tent can be directly connected to the lifting structure 5, or it can be placed on a transport vehicle via the lifting structure 5 and transported to a storage location. By using at least three lifting ropes 501 to perform the winding and releasing actions, the multiple lifting ropes 501 share the load of the tent, effectively suppressing the swaying and shaking of the tent during lifting and improving operational stability. The winding assembly winds up the lifting rope 501, which can lift the tent support base 105 and the entire roof tent; releasing the lifting rope 501 allows the tent to be lowered. When installing the tent, park the vehicle below the tent. The lifting structure 5 lowers the tent down to the roof of the vehicle. Then, the clamping structure 4 can be used to assemble and secure the tent to the roof rack 403. This tent assembly and disassembly device eliminates the need for multiple people to manually move the tent. It relies on mechanical lifting to complete the assembly and disassembly of the roof tent, effectively reducing manpower consumption and operational difficulty.

[0125] Furthermore, a pin 502 is fixed to the free end of the sling 501, and the tent support base 105 has a socket for engaging with the pin 502.

[0126] In the above technical solution, the suspension rope 501 and the tent support base 105 can be quickly connected and disconnected by the insertion of the pin 502 into the socket. The insertion method is simple to operate and can quickly complete the docking and separation of the suspension rope 501 and the tent support base 105. In the specific implementation process, in addition to the insertion structure, other detachable connection methods such as bolt locking and hook fastening can also be used, which provides flexible assembly options.

[0127] Furthermore, the winding assembly includes a frame 503, on which a winding shaft 504 is rotatably mounted, and a geared motor 505 is fixedly mounted on the frame 503. The output shaft of the geared motor 505 is fixedly connected to the winding shaft 504, and one end of the lifting rope 501 is fixedly connected to the winding shaft 504. The frame 503 has a through hole for the lifting rope 501 to pass through.

[0128] In the above technical solution, the output shaft of the geared motor 505 drives the winding shaft 504 to rotate, thereby realizing the winding or releasing action of the hoisting rope 501 fixed on the winding shaft 504. The through hole opened in the frame 503 allows the hoisting rope 501 to be threaded through, which plays a guiding and limiting role for the hoisting rope 501. The geared motor 505 can output a large torque, providing sufficient power for the raising and lowering of the tent. The overall structure is compact, realizing the mechanized winding and releasing operation of the hoisting rope 501.

[0129] Furthermore, the lifting rope 501 is provided with three ropes, two of which extend from the lower end of the frame 503 on both sides, and the other rope extends from the side of the frame 503. The winding assembly also includes a guide wheel 506, and the lifting rope 501 extending from the side passes around the guide wheel 506. Preferably, the free ends of the three lifting ropes 501 are flush.

[0130] In the above technical solution, three lifting ropes 501 are used to pull the tent support base 105 from different directions, distributing the load and effectively suppressing the swaying of the tent during the lifting operation. In actual implementation, four or more lifting ropes 501 can also be used to further optimize the force distribution and adapt to rooftop tents of different weight specifications.

[0131] Furthermore, the tent support base 105 is equipped with an electrical socket 507, which is electrically connected to the vehicle's internal power supply. The power cord 508 of the geared motor 505 is connected to the electrical socket 507 via an electrical plug. The geared motor 505 is directly powered by the vehicle's power supply, eliminating the need for an external power source. Specifically, the electrical plug and socket 507 can use compatible waterproof connectors, suitable for outdoor rooftop operations, protecting against rain and dew intrusion, reducing the risk of short circuits and leakage, and improving safety in humid environments. The plug and socket connection is easy to install and remove, allowing for quick disconnection of the power supply after operation, simplifying on-site wiring and facilitating the overall disassembly and storage of the device.

[0132] During the specific installation and layout, the frame 503 and the steering wheel 506 can be fixedly installed in a garage or other special work site; after installation, when it is necessary to dismantle the roof tent, simply drive the vehicle carrying the tent to the work position to carry out the lifting and dismantling operation.

[0133] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
