DETAILED DESCRIPTION

[0028] The utility model is described in detail below in conjunction with the accompanying drawings.

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] A foldable roof house with a gantry crane that is easy to unfold. Figure 1-5 As shown, the vehicle body 1 is provided with a chassis 2, and a U-shaped frame 3 is hinged on the chassis 2, and the two ends of the U-shaped frame 3 are respectively hinged to the two sides of the chassis 2; the chassis 2 is also provided with a folding plate assembly 4, and the folding plate assembly 4 is connected to the U-shaped frame 3 through a winch unit 5, and the folding plate assembly 4 includes side panels 41 arranged on all sides and a top cover 42 arranged on the top, and the side panels 41 include an inner folding left side panel and a right side panel and a flat opening front side panel and a rear side panel, and the inner sides of the left side panel and the right side panel are provided with a front track 10 corresponding to the front side panel and a rear track 11 corresponding to the rear side panel, and the left and right sides of the front side panel and the rear side panel are provided with rollers 12.

[0031] Specifically, the chassis 2 can be used to connect the vehicle body 1 and serve as a support for the entire folding room; after the U-shaped frame 3 is rotated to be vertical, it can provide an upward lifting support force to the winch unit 5, so that the folding plate assembly 4 placed flat when folded can be pulled upward to a vertical state to become the side walls of the folding room. This solution uses the winch unit 5 for lifting, which does not require the use of pressure liquid compared to the hydraulic system and is safer than the hydraulic system. When the hydraulic system fails, the hydraulic oil will leak. In addition, if the folding plate assembly 4 of this solution adopts a hydraulic system, multiple hydraulic rods are required, and then a control system is required for control, which is costly. The winch unit 5 itself is simpler than the hydraulic system, so its purchase price is lower than the hydraulic system. In addition, the maintenance cost of the hydraulic system is high, the maintenance cost of the winch unit 5 is low, and the motor life is longer. Furthermore, the winch unit 5 can be remotely controlled. In addition, as an optional design, in order to make the U-shaped frame 3 compatible with vehicles of different sizes, the side rods of the U-shaped frame 3 can be retractable, specifically, electrically controlled or hydraulically retractable. Further, when the folding plate assembly 4 is in the folded state, it is fixed to the base frame 2 by a safety buckle.

[0032] Furthermore, the top cover 42 is in a herringbone shape, the hoist body 51 and the small hoist 8 are both arranged inside the top cover 42, and the steel wire rope 52 of the hoist unit 5 passes through the top cover 42 and contacts the directional wheel 53. The left side plate and the right side plate can be hinged with the top cover 42, so that the top cover 42 is lifted from the horizontal to the vertical and unfolded during the lifting process. Since the left side plate and the right side plate adopt an inward folding method, when being stored, the top cover 42 descends, and the upper unit plate 43 and the lower unit plate 44 fold inward. If the front side plate and the rear side plate are also folded inward at this time, it is easy to interfere with the left side plate and the right side plate. Therefore, the lower ends of the front side plate and the rear side plate are hinged with the bottom frame 2, and can be retracted first during the folding process, and then the left side plate and the right side plate are automatically folded to avoid interference. Among them, since the shape of the board house is rectangular, the width of the front side plate and the rear side plate is equal to the spacing between the left side plate and the right side plate. Therefore, during the unfolding process of the front side plate and the rear side plate, it is easy to rub against the inside of the left side plate and the right side plate, causing the board house to be stuck when unfolding, and even causing damage to the side plate. Specifically, the track and roller 12 of this scheme protrude from the side plate setting. When the track and the roller 12 are in contact, the left and right side plates are pushed outward and misaligned with the front and rear side plates. The actual contact is only the track and the roller 12. Through the cooperation between the front track 10, the rear track 11 and the roller 12, the inside of the left side plate and the right side plate are protected to reduce friction. Furthermore, the front side plate and the rear side plate can also be lifted by a separate small winch 8 respectively. The small winch 8 is a double wheel that can realize forward and reverse rotation, thereby realizing the automatic unfolding of the front side plate and the rear side plate, reducing the manual workload. Specifically, the front and rear ends of the top cover are also provided with steering wheels 9.

[0033] As another specific embodiment, the rollers 12 are protruding to the left and right sides on the front side panels and the rear side panels; the front end of the front rail 10 and the rear end of the rear rail 11 are both provided with an outward expansion portion bent outward. During the unfolding process of the front side panels and the rear side panels, they are guided by the front rails 10 and the rear rails 11 on both sides respectively, and when they are about to be unfolded to the specified position, the distance between the front and rear side panels and the left and right side panels is gradually reduced by the outward expansion portion until they are completely in contact, completing the unfolding of the front and rear side panels.

[0034] As another specific embodiment, the front rail 10 and the rear rail 11 are both arc-shaped strips, and one end of the arc-shaped strip is provided with a side groove 13 which gradually expands outward along the direction and is used to place the roller 12. The arc-shaped strip can cooperate with the moving path of the roller 12, provide support for the roller 12, and open the left and right side panels. The side groove 13 can accommodate the roller 12, so that the roller 12 is embedded in the left and right side panels, so that the board room becomes a rectangular parallelepiped shape, and the side groove 13 can be self-locked to a certain extent, and can only be stored when the force on the front and rear side panels is sufficient to open the left and right side panels.

[0035] As another specific embodiment, the arc-shaped strip includes a fixed section 14 and a rotating section 15, the fixed section 14 is fixedly arranged on the left side panel or the right side panel, the rotating section 15 is rotatably connected to the fixed section 14, and the left side panel or the right side panel is provided with a fixing member for fixing the rotating section 15; the side groove 13 is provided on the fixed section 14. After the front and rear side panels are fixed, lifting the rotating section 15 can reduce the obstruction of the field of vision. And in the storage state, lifting the rotating section 15 can prevent interference when the left and right side panels are folded.

[0036] As another specific embodiment, the left side plate and the right side plate are both composed of an upper unit plate 43 and a lower unit plate 44, the upper end of the upper unit plate 43 is hinged to the top cover 42, the lower end of the upper unit plate 43 is hinged to the upper end of the lower unit plate 44, and the lower end of the lower unit plate 44 is hinged to the bottom frame 2. By hingedly setting the upper unit plate 43 and the lower unit plate 44, it is possible to achieve that the upper unit plate 43 and the lower unit plate 44 maintain connection with the top cover 42 and the bottom frame 2 while extending outward, and no manual operation is required during the entire unfolding process, which facilitates installation. As another specific embodiment, the hoisting unit 5 includes a hoisting machine body 51 and a steel wire rope 52, the hoisting machine body 51 is fixedly arranged in the upper middle part of the top cover 42, and the free end of the steel wire rope 52 is connected to the middle part of the U-shaped frame 3. According to this solution, the hoisting unit 5 is arranged on the upper part of the folding plate assembly 4 rather than on the U-shaped frame 3. When the hoisting unit 5 starts to operate, due to the light weight of the U-shaped frame 3, the angle between the hoisting unit 5 and the U-shaped frame 3 makes the wire rope 52 have a length difference when the U-shaped frame 3 is horizontal and vertical. The contraction of the wire rope 52 can rotate the U-shaped frame 3 in the vertical direction, thereby rotating the U-shaped frame 3 from the horizontal to the vertical state. Then, the hoisting unit 5 continues to operate, hoists itself, and then hoists the folding plate assembly 4 together, so that the folding plate assembly 4 is unfolded. At the same time, arranging the hoisting unit 5 on the upper part of the folding plate assembly 4 is also beneficial to the weight distribution of the entire folding room, preventing the hoisting unit 5 from exerting pressure on the U-shaped frame 3. Specifically, when the U-shaped frame 3 is in a horizontal state, when the viewing direction is the hoisting unit 5 retracting counterclockwise, the U-shaped frame 3 is placed to the right. Furthermore, the hoisting unit 5 further comprises a positioning wheel 53 disposed above the folding plate assembly 4, thereby preventing the steel wire rope 52 from being rubbed and fixing the extension direction. By lifting the middle part of the top cover 42, the top cover 42 can be prevented from tilting.

[0037] As another specific embodiment, when the U-shaped frame 3 is placed horizontally, the U-shaped frame 3 is located on the periphery of the base frame 2, and a rotating wheel 6 for steering the steel wire rope 52 is provided on the side of the folding plate assembly 4. Since the folding room needs to be folded and stored when not in use, and the U-shaped frame 3 is hinged on the base, the height of the U-shaped frame 3 in the storage state can be minimized when it is placed horizontally, so that the device meets the requirements of driving safety traffic regulations. The folding plate assembly 4 is located above the base frame 2, and the height of the positioning wheel 53 is higher than the height when the U-shaped frame 3 is placed horizontally. The steel wire rope 52 can be steered by the rotating wheel 6 to prevent the steel wire rope 52 from rubbing against the folding plate assembly 4. Furthermore, the top height of the rotating wheel 6 is higher than the top height of the positioning wheel 53, which can ensure that the U-shaped frame 3 rotates upward smoothly.

[0038] As another specific implementation, the base frame 2 is provided with a locking mechanism 7 for fixing the U-shaped frame 3 to be in a vertical state. Since the hoisting unit 5 needs to lift the folding plate assembly 4 after rotating the U-shaped frame 3, and when lifting the folding plate assembly 4, the U-shaped frame 3 is used to bear the force, in order to prevent the U-shaped frame 3 from shaking when lifting the folding plate assembly 4, the U-shaped frame 3 is fixed after the U-shaped frame 3 is turned to a vertical state. Specifically, the following feasible implementations are proposed for the locking mechanism 7.

[0039] In the first embodiment, the locking mechanism is a hook support rod 71, one end of which is hinged to the base frame 2, and the other end can be hung on the U-shaped frame 3, so that the U-shaped frame 3 is obliquely supported, that is, the base frame 2, the U-shaped frame 3 and the hook form a triangular stable structure; thereby, the U-shaped frame 3 can be stably maintained in an upright state.

[0040] In the second embodiment, the locking mechanism is a tension spring 72 and a stopper 73, one end of the tension spring 72 is fixedly connected to the base frame 2, and the other end is fixedly connected to the U-shaped frame 3, and when the U-shaped frame 3 is in an upright state, the tension spring has an elastic force, so that the U-shaped frame 3 and the stopper 73 are kept in contact with each other, so that the U-shaped frame 3 can be stably kept in an upright state; of course, the stopper 73 is arranged on the base frame 2 and is located behind the U-shaped frame 3 (the U-shaped frame 3 rotates backward when it is changed from inverted to upright).

[0041] In the second embodiment, the stopper 73 is preferably a U-shaped block, and when the U-shaped frame 3 is in an upright position, the U-shaped frame 3 is located inside the U-shaped block.

[0042] In the second embodiment, the stopper 73 is preferably installed above the hinged position of the U-shaped frame 3 and the base frame 2, that is, the installation of the stopper 73 will not interfere with the rotation of the U-shaped frame 3, thus avoiding motion interference.

[0043] In this embodiment, the locking mechanism 7 preferably adopts the second implementation mode, because the second implementation mode can not only make the U-shaped frame 3 stably maintain the upright state; and when the folding plate assembly 4 is lifted to unfold it, there is no need to stop the winch body 51 to fix the U-shaped frame 3 in the middle, and the tension spring 72 can also provide force for the rotation of the U-shaped frame; secondly, when the U-shaped frame 3 is rotated to the upright state, due to the limitation of the tension spring 72, the U-shaped frame 3 will not swing greatly due to the sudden stop of rotation, which effectively reduces the fatigue damage of the U-shaped frame 3; finally, when the U-shaped frame 3 is transformed from upright to inverted, the tension spring 72 can also align for buffering, and convert the gravitational potential energy and kinetic energy released during the rotation of the U-shaped frame 3 into the potential energy of the tension spring 72 (the potential energy is released during the rotation of the U-shaped frame 3 to the upright state), so as to prevent the U-shaped frame 3 from seriously colliding with other components when it is inverted, thereby protecting the U-shaped frame 3 and other components.

[0044] As another specific embodiment, the front side plate and / or the rear side plate are further hinged with a table top, and the table top is hinged with table legs. The foldable table top can be conveniently used during camping.

[0045] As another specific embodiment, a window 45 is provided on the folding board assembly 4. The interior space of the board house is limited. If there is no window for ventilation, the air will not circulate, affecting the living environment and people's health. Opening the window allows fresh air to enter the room, while exhausting the dirty air in the room, keeping the indoor air fresh and dry.

[0046] As another specific embodiment, an opening is provided above the vehicle body 1. Through the opening, people can enter the folding room from the inside of the vehicle.

[0047] As another specific embodiment, a solar panel is further provided above the folding plate assembly 4 to provide power for the winch assembly 5 and activities within the vehicle.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The present invention is extended to any new features or any new combination disclosed in this specification, and any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.

[0049] In the description of the embodiments of the present invention, it should be understood that the terms "length", "width", "vertical", "horizontal", "top", "bottom", etc. indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.
