Roof platforms, roof tents and roof assemblies

Abstract

This invention provides a roof platform, a roof tent, and a roof assembly. The roof platform includes a frame formed by at least two connected poles, extending horizontally and defining a cavity for accommodating the roof tent. The cavity opens upwards, defining a tent opening on the top surface of the frame. This tent opening allows the roof tent to be deployed from the cavity and / or folded into the cavity. The cavity allows the folded roof tent to be completely embedded within the frame, preventing the tent from forming a separate protrusion above the frame and significantly reducing wind resistance. The separate poles and corner connectors are all located within the frame; airflow passes through the frame and does not directly reach these structures, avoiding high-frequency turbulence that can easily occur when airflow passes over the separate poles and corner connectors, thus reducing wind noise.

Description

Technical Field

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

[0002] Rooftop platforms with integrated folding roof tents have become common equipment for outdoor travel. However, with current technology, even when the tent is folded up for the necessary driving position, significant wind resistance and wind noise issues still exist. The original vehicle roof has a smooth aerodynamic profile, but the folded tent and rooftop platform frame disrupt this shape: although the folded tent is smaller, it still forms a non-streamlined protrusion above the roof, which, together with the base frame, increases the frontal area. After airflow impacts, turbulent vortices are formed on the protruding surface and in the gaps of the frame, resulting in a significant increase in wind resistance. Especially at speeds exceeding 120 km / h, the increase in wind resistance significantly reduces fuel economy. According to actual tests, this structure may increase fuel consumption by 5% to 20%. Wind noise is also a prominent issue. When airflow passes through the split frame, corner connectors, and assembly gaps, it easily generates high-frequency turbulence, creating whistling or booming sounds. The noise intensifies significantly at speeds above 80 km / h. Furthermore, if the folded tent fabric is not tightly fitted to the metal frame, it is prone to vibration and abnormal noise due to airflow impact. Insufficient fit between the frame and the roof further amplifies vibration and noise, severely impacting the driving experience. These wind resistance and wind noise defects are the main pain points of existing foldable rooftop tent platforms. Utility Model Content

[0045] This utility model also provides a roof assembly, including:

[0046] The roof platform described in any of the above items;

[0047] The rooftop tent described in any of the preceding claims is connected to a receiving cavity in the rooftop platform and is configured to be deployed in one of the following ways:

[0048] In the first method, the canvas portion of the rooftop tent remains within the receiving cavity, while the other portion unfolds from the top opening of the receiving cavity, thereby causing the rooftop tent to open into the external space of the receiving cavity.

[0050] In this utility model, the roof platform, roof tent, and roof assembly feature a receiving cavity that allows the folded roof tent to be completely embedded within the frame, preventing the tent from forming a separate protrusion above the frame. This not only reduces the windward area but also avoids the formation of turbulent eddies, significantly reducing wind resistance. The separate support poles and corner connectors are all located within the frame; airflow passes through the frame and does not directly reach these structures, avoiding high-frequency turbulence that can easily occur when airflow passes through the separate support poles, corner connectors, and assembly gaps, thus reducing wind noise. The frame, as a unified carrier, can be pre-positioned to improve its fit with the roof, avoiding vibration amplification caused by insufficient fit between the traditional support poles and the roof, further reducing noise. These features effectively solve the wind resistance and wind noise problems caused by roof tents, thereby improving the user experience.

[0061] The following reference Figures 1 to 8 This description describes a rooftop platform, rooftop tent, and rooftop assembly according to embodiments of the present invention. In this description, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature, that is, include one or more of that feature.

When a feature "includes or contains" one or more of the features it encompasses, unless otherwise specifically described, this indicates that other features are not excluded and may be further included.

[0062] Unless otherwise expressly specified and limited, the terms "set," "install," "connect," "link," "fix," and "couple" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art should be able to understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0063] Furthermore, in the description of this embodiment, "above" or "below" the second feature can include direct contact between the first and second features, or it can include contact between the first and second features through another feature between them.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0065] Figure 1 This is a schematic structural diagram of the top surface of a roof platform according to an embodiment of the present invention, as shown below. Figure 1 As shown, and refer to Figures 2 to 8 This utility model embodiment provides a roof platform 10, including a frame body formed by connecting at least two frame poles. The frame body extends in a horizontal plane and defines a receiving cavity for accommodating a roof tent. The receiving cavity opens upward and defines a roof tent opening 101 on the top surface of the frame body. The roof tent opening 101 is used to unfold the roof tent from the receiving cavity and / or fold the roof tent into the receiving cavity.

[0066] The accommodating cavity allows the folded roof tent to be completely embedded within the frame, preventing the tent from becoming a separate protrusion above the frame. This not only reduces the windward area but also avoids the formation of turbulent eddies, significantly reducing wind resistance. The separate support poles and corner connectors are all within the frame; airflow passes through the frame and does not directly reach these structures, avoiding high-frequency turbulence that can easily occur when airflow passes through the separate support poles, corner connectors, and assembly gaps, thus reducing wind noise. The frame, as a unified carrier, can improve its fit with the roof through pre-set mounting positions, avoiding vibration amplification caused by insufficient fit between the traditional support poles and the roof, further reducing noise. These features address the wind resistance and wind noise issues caused by roof tents, improving the user experience. The accommodating cavity is not necessarily U-shaped but depends on the accommodating method. For example, if the cavity only serves a accommodating function, it can be of any shape, as long as it can accommodate the roof tent. For instance, if the tent can be folded back into a pole shape, the accommodating cavity can also be pole-shaped. For example, the cavity can be integrated with the platform storage compartment on the lower side of the frame.

[0067] In some embodiments of this utility model, such as Figure 6 As shown, the frame includes a partition 130, which forms the cavity wall of the receiving cavity and is used to prevent the roof tent from expanding out or falling out of the receiving cavity.

[0068] During vehicle operation, bumps and turns can generate lateral or longitudinal impacts, causing the folded roof tent to sway within the enclosure, or even bulge out or detach from the upward opening of the enclosure due to excessive impact. The partition frame, acting as the enclosure wall, provides physical restraint to the tent from all sides, securing it within the pre-set area of ​​the enclosure.

[0069] Furthermore, in some embodiments of this utility model, such as Figure 6 As shown, the isolation frame 130 is in the form of a continuous plate at the positions of the two side walls and one bottom wall of the receiving cavity, so that the overall shape of the isolation frame 130 is a box shape with an upward opening.

[0070] The continuous plate structure is seamless and uninterrupted, which prevents the roof tent components from protruding through the gaps in the partition frame or coming into direct contact with external objects, reducing the risk of component wear, tear, or deformation.

[0071] In some other embodiments of the present invention, the partition frame is in the form of a continuous plate or railing at at least one of the two side walls and one bottom wall of the receiving cavity.

[0072] In some embodiments of this invention, the accommodating cavity follows a continuous or discontinuous open groove-shaped enclosure. This design further enhances the storage and protection of the rooftop tent.

[0073] In some embodiments of the present utility model, as Figure 1 shown, the length dimension of the frame body in the front-rear direction is greater than the width dimension in the left-right direction, and the extending direction of the accommodation cavity has an opening facing right, so as to facilitate the roof tent to be rotated, folded and retracted in the left-right direction.

[0074] The arrangement that the front-rear length of the frame body is greater than the left-right width and the opening of the extending direction of the accommodation cavity facing left or right enables the roof platform 10 to fully adapt to the transverse spatial characteristics of the vehicle roof, and simplifies the folding and retracting operation.

[0075] Certainly, in other embodiments of the present utility model, the opening of the extending direction of the accommodation cavity may also face left.

[0076] In some embodiments of the present utility model, the extending direction of the accommodation cavity is a U-shaped, C-shaped, G-shaped or several-shaped open slot-shaped enclosed extending path.

[0077] In some embodiments of the present utility model, as Figure 4 shown, the frame body includes a base sub-frame 110 and an expansion sub-frame 120. The base sub-frame 110 extends in the horizontal direction and is configured to be connected or will be connected to the vehicle roof cover. The expansion sub-frame 120 also extends in the horizontal direction and is reciprocally and slidably connected to the expansion side of the base sub-frame 110. The expansion sub-frame 120 can be pulled out from and inserted back into the expansion side of the base sub-frame 110. The accommodation cavity is located on the base sub-frame 110, and its extending direction opening faces the expansion side of the base sub-frame 110.

[0078] The base sub-frame 110 is configured to be connected or will be connected to the vehicle roof cover, so as to realize the fixation between the roof platform 10 and the vehicle roof cover. When the user needs to expand the space of the roof platform 10, the expansion sub-frame 120 can be pulled out from the expansion side of the base sub-frame 110 to increase the transverse space of the roof platform 10. When rest is not needed, the expansion sub-frame 120 can also be inserted back into the base sub-frame 110. The expansion sub-frame 120 increases the width capacity of the roof platform 10 and improves the comfort of user experience.

[0079] In other embodiments of the present utility model, the accommodation cavity is located on the expansion sub-frame 120, and in the inserted state of the expansion sub-frame 120, its extending direction opening faces away from the expansion side of the base sub-frame 110.

[0080] In some embodiments of the present utility model, as Figure 5 shown, a roof storage cavity opening toward the expansion side is defined at the bottom of the base sub-frame 110, and the expansion sub-frame 120 has a first longitudinal frame 123 configured to open and close the opening of the roof storage cavity, so that the opening of the roof storage cavity is opened when the expansion sub-frame 120 is in the pulled-out state, and the opening of the roof storage cavity is closed when the expansion sub-frame 120 is in the inserted state.

[0081] The roof storage compartment is located at the bottom of the base subframe 110, without occupying the space above the frame used for placing the roof tent, and unlike external storage boxes, it does not increase the roof protrusion. The first longitudinal frame 123 is similar to a door for the storage compartment; when inserted, it can completely close the opening to avoid wind resistance and wind noise during driving. When pulled out, it can fully open the opening.

[0082] In some embodiments of this utility model, when the receiving cavity is located on the base subframe 110, the receiving cavity is sunk into the roof storage cavity, and an isolation frame is provided between the receiving cavity and the roof storage cavity.

[0083] In some embodiments of this utility model, such as Figures 4 to 7 As shown, the frame includes a base subframe 110 and an extension subframe 120. The base subframe 110 includes two transverse side frames 111 spaced apart front to back, connected by a U-shaped, right-opening partition 130. A U-shaped receiving cavity is defined on the partition. At least two laterally extending fixed support rods 113 are formed on the concave side of the partition, spaced apart in the front-rear direction. Left-right extending extension grooves 114 are defined on the opposing sides of adjacent fixed support rods 113, with the left end of the extension groove 114 blocked by the partition and its right end open. The bottom of each fixed support rod 113 is higher than the bottom of the two transverse side frames 111 and / or the bottom of the partition, forming a right-opening roof storage cavity below each fixed support rod 113, located between the two transverse side frames 111 and / or on the concave side of the partition. The extension subframe 120 includes a first movable frame rod 121 inserted between two adjacent fixed frame rods 113. The left end of each first movable frame rod 121 is connected to a wheel 122 via a front-to-back axle. The right end of each first movable frame rod 121 is connected to a first longitudinal frame 123. The bottom of the first longitudinal frame 123 is lower than the bottom of the fixed frame rods 113, so that the right-facing opening of the roof storage compartment can be opened and closed through the first longitudinal frame 123. The wheel 122 is either a roller that rolls within the extension groove 114 or a pulley that slides within the extension groove 114.

[0084] The first movable support rod 121 of the extension sub-frame 120 is inserted between adjacent fixed support rods 113 of the base sub-frame 110. The wheel 122 is fully accommodated within the extension slide 114, and its displacement is restricted by the left end blocked by the partition frame. The first longitudinal frame 123 fits against the right side of the base sub-frame 110, with its bottom lower than the bottom of the fixed support rod 113, thus just covering the right-facing opening of the roof storage cavity. Pulling the first longitudinal frame 123 to the right causes all the first movable support rods 121 connected to it to move synchronously. The first movable support rod 121 drives the wheel 122 to roll within the extension slide 114. Because the right end of the extension slide 114 is open and unobstructed, the wheel 122 can move smoothly to the right along the slide, avoiding jamming when the first movable support rod 121 is inserted or removed. As the extension sub-frame 120 moves to the right as a whole, the first longitudinal frame 123 gradually moves away from the right side of the base sub-frame 110. When a reset is required, push the first longitudinal frame 123 to the left, and the wheel 122 rolls to the left along the extended slide 114 until the wheel 122 touches the isolation frame at the left end of the extended slide 114. The first longitudinal frame 123 then re-fits the right side of the base sub-frame 110, and the roof storage cavity opening closes.

[0085] In some embodiments of this utility model, such as Figure 7 As shown, the upper groove edge of the extended groove 114 is folded downward and the lower groove edge is folded upward to form a downward folded edge. Correspondingly, a waistline wheel groove is defined on the wheel surface of the wheel member 122, which is in concave-convex cooperation with the downward folded edge. The waistline wheel groove divides the wheel member 122 into an inner wheel section inside the extended groove 114 and an outer wheel section outside the extended groove 114. The axial length of the outer wheel section is less than or equal to the axial length of the inner wheel section.

[0086] By forming a concave-convex fit between the folded edge of the extended slide 114 and the waistline wheel groove of the wheel 122, the stability of the extension sub-frame 120 can be improved.

[0087] In some other embodiments of this utility model, the upper groove edge of the extended groove 114 is folded downward.

[0088] In some other embodiments of this utility model, the lower groove edge of the extended groove 114 is folded upward to form a downward folded edge.

[0089] In some embodiments of this utility model, such as Figure 2 and Figure 5 As shown, the bottom of each fixed bracket 113 is connected to a longitudinal bracket 119 near the right end. The bottom of the longitudinal bracket 119 is higher than the bottom of the roof storage cavity, and its bottom is connected to or will be connected to a laterally extending base bracket 115. The left end of the base bracket 115 is connected to or will be connected to the bottom of the left side portion of the partition 130, and the base bracket 115 is used to connect to or will be connected to the roof cover.

[0090] The structural strength of the roof platform 10 is improved by the cooperation of the fixed frame rod 113, the longitudinal frame rod 119 and the base frame rod 115.

[0091] In some embodiments of the present invention, a longitudinally extending strut groove is defined at the bottom of the first longitudinal frame 123. The strut groove opens downward and is hinged to an extension strut 124. The extension strut 124 is configured to be flip-up and extendable in the length direction.

[0092] When the extension sub-frame 120 is pulled out, the extension sub-frame 120 is suspended. To increase the support strength of the extension sub-frame 120, the extension support rod 124 in the support rod groove can be flipped to a vertical state and extended to the bottom to touch the bottom and bear the force, thereby providing support for the extension sub-frame 120.

[0093] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, each of the two horizontal frame frames 111 defines a first cavity 117 that opens to the left. Each first cavity 117 is connected to at least one telescopic rod 128 that can be pulled out to the left. The left ends of the two telescopic rods 128 are connected to the second vertical frame frame 127. A roller blind mechanism is connected between the second vertical frame frame 127 and the partition frame, causing the roller blind mechanism to roll up when the telescopic rods 128 are retracted and to unfold when they are extended. A roller blind cover plate is also fixed to the left side of the partition frame. The roller blind cover plate is used to cover the space between the partition frame and the second vertical frame frame 127 when the telescopic rods 128 are retracted.

[0094] When the roller blind mechanism is rolled up, the telescopic rod 128 is fully retracted into the first cavity 117 of the horizontal frame 111. At this time, there is no excess protrusion on the left side, the overall structure is compact, it does not occupy the space on the left side of the roof, does not affect the wind resistance when the vehicle is in motion, and does not interfere with the raising and lowering of the tent inside the cavity. When it is necessary to unfold the roller blind structure, the second longitudinal frame 127 is pulled to the left, causing the telescopic rods 128 at both ends to be simultaneously pulled out to the left from the first cavity 117 of the horizontal frame 111. As the telescopic rods 128 extend, the originally rolled-up roller blind mechanism is simultaneously pulled open along with the leftward movement of the second longitudinal frame 127, unfolding into a flat shape and covering the area between the left side of the isolation frame and the second longitudinal frame 127. The unfolded roller blind mechanism forms a protective barrier on the left side, which can block sunlight and wind and rain, and can be used as a temporary activity area.

[0095] In some embodiments of this utility model, such as Figures 3 to 5As shown, the base subframe 110 also includes guide rods 116, which are arranged parallel and spaced apart between the fixed rod 113 and the isolation frame 130. Correspondingly, the extension subframe 120 also includes a second movable rod 125, the bottom of which defines a guide groove that opens downward and to the left. The guide groove and the guide rod 116 are slidably fitted together to cause the second movable rod 125 to slide laterally back and forth along the guide rod 116.

[0096] The sliding sleeve of the guide groove and the guide rod 116 fits together to ensure that the expansion subframe 120 does not deviate during opening and closing.

[0097] In some other embodiments of this utility model, the guide rods 116 are arranged in parallel and spaced apart between two adjacent fixed rods 113.

[0098] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, each of the two horizontal frame borders 111 defines a second cavity 118 that opens at least to the right. Correspondingly, the front and rear ends of the first vertical frame border 123 are respectively connected to a third moving bracket 126 extending laterally, and the third moving bracket 126 is inserted and inserted into the second cavity 118 of the corresponding horizontal frame border 111.

[0099] The third moving frame rod 126 can increase the support strength of the extension sub-frame 120. At the same time, the third moving frame rod 126 can be inserted and inserted into the second cavity 118 of the corresponding horizontal frame 111 to ensure that the extension sub-frame 120 does not deviate during the opening and closing process.

[0100] In some embodiments of this utility model, at least one first moving frame rod 121 is connected to three sets of wheels. Each set of wheels includes two wheels 122 symmetrically distributed on the front and rear sides of the first moving frame rod 121. Two of the three sets of wheels are located at the two ends of the first moving frame rod 121, and the other is located near the left end of the first moving frame rod 121.

[0101] Specifically, the three sets of wheels are numbered from left to right, with the third set only entering the extension slide 114 when the extension subframe 120 is retracted, while the first and second sets remain in the extension slide 114 at all times. This configuration also ensures that the wheels do not deviate from their designated position during the opening and closing of the extension subframe 120.

[0102] In some other embodiments of this utility model, spring pins and locking holes can be provided between the first moving frame rod 121 and the longitudinal frame rod 119 to ensure that the extension subframe 120 does not deviate during the opening and closing process.

[0103] In some embodiments of this utility model, such as Figure 6As shown, in the case that a first cavity and a second cavity are defined on two transverse frames, the first cavity is located on the lower side of the second cavity, and the cross-sectional area of the first cavity is larger than that of the second cavity.

[0104] In some embodiments of the present utility model, as Figures 3 to 5 shown, under the condition that the transverse frame is connected to the second longitudinal frame via a telescopic rod and connected to the first longitudinal frame via a third movable frame rod, at least one of the two transverse frames, the first longitudinal frame and the second longitudinal frame defines an interface groove extending along the length direction of the frame on the side away from the center of the frame body. The interface groove can be used to connect one end of a roller shutter, so that the roller shutter can be opened or retracted following the second longitudinal frame.

[0105] In some embodiments of the present utility model, the interface groove is a continuous or intermittent T-shaped groove, C-shaped groove, dovetail groove or G-shaped groove.

[0106] In some embodiments of the present utility model, as Figure 1 and Figure 2 shown, under the condition that the transverse frame is connected to the second longitudinal frame via a telescopic rod, the left ends of the two transverse frames are exposed from the left side of the isolation frame, the exposed parts are flush with or extend beyond the roller shutter cover plate, and the exposed parts abut against the right side of the second longitudinal frame, so that when the telescopic rod is in the retracted state, both ends of the second longitudinal frame are fittingly engaged with the left ends of the two transverse frames. The left ends of the two transverse frames exposed from the left side of the isolation frame can define the position of the second longitudinal frame when retracted, and can also support the roller shutter cover plate, which serves two purposes at once.

[0107] In some embodiments of the present utility model, as Figure 6 shown, in the case that the overall shape of the isolation frame is box-shaped, the isolation frame includes a first frame rod and a second frame rod. The cross section of the first frame rod is L-shaped, and it includes a vertical wall and a bottom wall, and at least one of the vertical wall and the bottom wall defines a flat third cavity extending in the rod length direction of the first frame rod. Moreover, in the case that the third cavity exists in both the vertical wall and the bottom wall, ribs are arranged in the third cavity of at least one of the two, so that the cross section of the third cavity is in the shape of a Chinese character "日" or "目". The second frame rod is joined to the side of the bottom wall of the first frame rod away from the vertical wall, so that the first frame rod and the second frame rod enclose a U-shaped groove cavity with an upward opening.

[0108] The first support rod 131 and the second support rod 132 enclose an upward-opening U-shaped cavity. The addition of ribs can increase the strength of the corresponding vertical walls and / or bottom walls, thereby increasing the support strength of the isolation frame.

[0109] In some embodiments of this utility model, a first support rod 131 and a second support rod 132 are connected to form a support rod unit. The isolation frame includes three support rod units, which are connected sequentially in a U-shape to form an upward-opening U-shaped receiving cavity.

[0110] The three support units can improve the overall strength of the U-shaped cavity.

[0111] In some embodiments of this utility model, a top tent cover 140 is detachably and / or hingedly and / or slidably connected to the frame body, and the top tent cover 140 is used to block the top tent opening 101.

[0112] By sealing the opening 101 of the tent with the tent cover 140, the wind resistance and wind noise caused by the opening 101 of the tent during vehicle operation can be reduced.

[0113] In some embodiments of this utility model, such as Figure 5 As shown, when the direction of the receiving cavity is U-shaped or C-shaped, the top cover 140 can be of the first type: there are multiple top covers 140, and the multiple top covers 140 are arranged sequentially and relatively independently in the direction of the receiving cavity, so that each top cover 140 can open and close a part of the top opening 101 relatively independently.

[0114] There are multiple top cover 140s, and each top cover 140 can be relatively small in size to facilitate production and processing.

[0115] Furthermore, in some embodiments of this utility model, such as Figure 5 As shown, when the roof cover 140 is of the first structure and is hinged to the frame, each roof cover 140 is hinged to the side edge of the roof opening 101 of the receiving cavity away from its direction opening, so that each roof cover 140 is located outside the roof tent after being deployed from the roof tent.

[0116] In some other embodiments of this invention, when the cavity is U-shaped or C-shaped, the top cover 140 can also have a second structure: the shape of the top cover 140 matches and complements the top opening 101 of the cavity. The top cover 140 is a single unit, which facilitates assembly.

[0117] Furthermore, in some embodiments of this utility model, when the shape of the top cover 140 matches and complements the top opening 101 of the receiving cavity, and it is hinged to the frame body, the two ends of the top cover 140 are respectively hinged to the two ends of the trend of the top opening 101 of the receiving cavity.

[0118] In some embodiments of this invention, the top opening 101 of the receiving cavity is flush with or lower than the top surface of the frame, and the bottom of the receiving cavity is flush with or higher than the bottom surface of the frame. This arrangement prevents a bulge from forming on the top surface of the frame after the tent is stowed, thus avoiding increased wind resistance and wind noise.

[0119] This embodiment also provides a rooftop tent suitable for the rooftop platform 10 of any of the above embodiments, such as... Figures 3 to 8 As shown, the device includes a connecting seat 210 and a tent mechanism. The connecting seat 210 is used to insert into a receiving cavity of the roof platform 10. The tent mechanism is folded and unfolded by at least one piece of canvas, which can be stretched by means of a stretching unit, wherein the stretching unit is provided with at least one tent pole, which is connected to or will be connected to the canvas, and at least one end of which is connected to the connecting seat 210. The connecting seat 210 is used to unfold the tent mechanism from the receiving cavity and fold it into the receiving cavity.

[0120] The tent poles connect to the canvas and are fixed to the connector 210, forming a stable support structure. When deployed, the tent poles provide even support to the canvas, reducing swaying or deformation caused by wind and other external forces, improving the tent's wind resistance during outdoor use, preventing safety hazards such as collapse, and ensuring safety during camping.

[0121] In some embodiments of this utility model, such as Figure 8 As shown, one tent pole is a gantry pole 221 with at least one end connected to the connecting seat 210, and the other tent pole is a curtain pole 222 that can be freely swung to or will be connected to the gantry pole 221. A hanging plate 223 is rotatably connected to the curtain pole 222. One end of the hanging plate 223 is rotatably connected to the curtain pole 222 at a position near the gantry pole 221, and the other end forms a hook portion. The hook portion is used to hook onto or will hook onto the gantry pole 221 to lock the curtain pole 222 onto the gantry pole 221.

[0122] When the canvas is unfolded, the gantry rod 221, which serves as the basic support, is connected to the connecting seat 210 at one end and will be in the unfolded basic support state synchronously with the canvas, providing a connection base for the curtain rod 222. Next, the freely swinging curtain rod 222 is pushed. Since the curtain rod 222 and the gantry rod 221 are connected in a swingable manner, the swing angle of the curtain rod 222 can be adjusted as needed. When the curtain rod 222 swings to the target position, the hanging plate 223 on the curtain rod 222 near the gantry rod 221 is rotated. The hook at the other end of the hanging plate 223 is aligned with the appropriate position on the gantry rod 221, and the hook is attached to the gantry rod 221. At this time, the curtain rod 222 is firmly locked to the gantry rod 221 by the hanging plate 223, preventing it from swinging arbitrarily, and the curtain remains in a taut state after unfolding, forming a stable door structure. When storing, first rotate the hanging plate 223 in the opposite direction to disengage the hook from the door frame rod 221, thus releasing the locking relationship between the curtain rod 222 and the door frame rod 221. Then, swing the curtain rod 222 in the opposite direction towards the door frame rod 221. The curtain will naturally loosen and retract after losing the support of the curtain rod 222. After the curtain rod 222 and the door frame rod 221 are aligned and neat, close the top cover 140.

[0123] In some embodiments of this utility model, such as Figure 8 As shown, a T-shaped adjusting groove 225 extending along the length of the gantry rod 221 is defined on at least one side. An adjusting nut is slidably and anti-rotatingly installed in the adjusting groove 225. The adjusting nut is slidably snapped onto a slide block 224 on the gantry rod 221 via a locking bolt, so that the lower end of the curtain rod 222 is rotatably connected to or will be connected to the slide block 224.

[0124] When the position of the curtain rod 222 needs to be adjusted, loosen the locking bolt. At this time, the adjusting nut can drive the slide 224 to slide freely along the adjusting groove 225 until the slide moves to the target height position. Tighten the locking bolt so that the adjusting nut and the slide together clamp the side wall of the groove of the gantry rod 221, and firmly fix the slide in the current position.

[0125] This embodiment also provides a roof assembly, including a roof platform 10 and a roof tent from any of the above embodiments, connected to a receiving cavity of the roof platform 10, and configured to unfold in one of the following ways: First, a portion of the canvas in the roof tent remains within the receiving cavity, while the remaining portion unfolds from the top opening 101 of the receiving cavity, thereby opening the roof tent to the external space of the receiving cavity. Second, the entire canvas in the roof tent unfolds from the receiving cavity, thereby opening at least one side of the roof tent towards the receiving cavity.

[0126] The first option is a semi-opening mode, suitable for short stays, temporary rest, or ventilation needs. For example, if you only need temporary shade, shelter from light rain, or a partially open space when resting in a vehicle, you don't need to fully open the tent. This allows for quick use and reduces operation time.

[0127] The second option is the fully unfolded mode, suitable for long-term camping or sleeping needs. When fully unfolded, the canvas creates a completely enclosed space, providing a larger area for activities or rest, meeting the spatial requirements of deep camping.

[0128] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
