DETAILED DESCRIPTION

[0026] The utility model is described in detail below in conjunction with the accompanying drawings.

[0027] 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.

[0028] A structurally stable automobile gantry crane linked folding roof house, such as Figure 1-7 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 a fastening connection device 10 is provided between the folding plate assembly 4 and the U-shaped frame 3.

[0029] 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 vehicle models of different sizes, the side rods of the U-shaped frame 3 can be designed to be retractable, specifically, electrically controlled retractable or hydraulically retractable. A fastening connection device 10 is provided between the folding plate assembly 4 and the U-shaped frame 3. After the folding plate assembly 4 is unfolded, the folding plate assembly 4 and the U-shaped frame 3 are fixed by the fastening connection device 10, which can ensure that the folding plate assembly 4, especially the left and right plates, are in a stable unfolded state and unfolded completely, without blocking the unfolding of the front and rear side plates, and can also fix the position of the U-shaped frame 3 so that it is fixed in a vertical position.

[0030] As another specific embodiment, the fastening connection device 10 includes a tensioning rope 101, the inner end of which is fixedly connected to the folding plate assembly 4, and the outer end of which is arranged on the U-shaped frame 3 through a rope winding device 102; or, the inner end of the tensioning rope 101 is fixedly connected to the folding plate assembly 4, the middle part of the tensioning rope 101 is slidably connected to the U-shaped frame 3, and the outer end of the tensioning rope 101 is arranged on the base frame 2 through a rope winding device 102. Specifically, the fastening connection device 10 is to tighten the folding plate assembly 4 so that the folding plate assembly 4 and the U-shaped frame 3 are close together, so the tensioning rope needs to be arranged between the folding plate assembly 4 and the U-shaped frame 4. However, since the U-shaped frame 3 will rotate, it is preferred that the rope winding device 102 is arranged on the base frame 2 and passes through a certain position of the U-shaped frame 3. When the tensioning rope is shortened, the gap between the folding plate assembly 4 and the U-shaped frame 3 is reduced to achieve close contact. Moreover, the rope winding device 102 is arranged on the base frame 2, which can be conveniently operated manually to rewind and release the tension rope 101. The tension rope 101 can be formed by twisting multiple strands of steel wire, has high tensile strength, and can withstand huge tensile force without breaking easily.

[0031] As another specific embodiment, the rope winding device 102 is arranged on the outside of the U-shaped frame 3 or the base frame 2, and a rope passing pulley is arranged on the U-shaped frame 3. The outer end of the tension rope 101 passes through the rope passing pulley and is arranged on the rope winding device 102. The rope passing pulley can prevent the tension rope from causing wear to the U-shaped frame, and can guide the tension rope. Further, the rope passing pulley is a frame-shaped four-way pulley, and the tension rope 101 passes through the frame.

[0032] As another specific embodiment, the rope winding device 102 includes a rotating shaft 1021, which is arranged on the U-shaped frame 3 or the bottom frame 2 through a base 1022, a ratchet 1023 is arranged on one side of the rotating shaft 1021, and a ratchet 1024 matching the ratchet 1023 is hinged on the base 1022; a rotating part 1025 is arranged on the other side of the rotating shaft 1021. The rotating part can obtain the power of rotation from manual or motor, so as to reel or release the tension rope; the ratchet 1023 and the ratchet 1024 can realize one-way transmission, allowing the tension rope to be freely reeled in, and being locked when releasing the tension rope, without the need for additional force to maintain the locked state; and when releasing, the ratchet 1024 can be opened to release the lock.

[0033] As another specific embodiment, the hoisting unit 5 includes a hoisting unit body 51 and a steel wire rope 52. The hoisting unit body 51 is fixedly arranged on the upper part of the folding plate assembly 4, 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 compared to being arranged 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 steel wire rope 52 have a length difference when the U-shaped frame 3 is horizontal and vertical. The contraction of the steel wire rope 52 can rotate the U-shaped frame 3 in the vertical direction, thereby rotating the U-shaped frame 3 from the horizontal state 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, and prevents 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. Further, the hoisting unit 5 also includes a positioning wheel 53 arranged above the folding plate assembly 4, thereby preventing the steel wire rope 52 from being rubbed and fixing the extension direction.

[0034] 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 frame 2, 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.

[0035] 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 winch 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.

[0036] 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.

[0037] 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).

[0038] 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.

[0039] 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.

[0040] 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.

[0041] As another specific embodiment, the folding plate assembly 4 includes side panels 41 arranged on all sides and a top cover 42 arranged on the top, and the hoisting unit 5 is arranged in the middle of the top cover 42. By lifting the middle of the top cover 42, the top cover 42 can be prevented from tilting. The side panels 41 can be hinged with the top cover 42, so that the top cover 42 is lifted from horizontal to vertical during the lifting process; or they can be detachably connected with the top cover 42, and after the top cover 42 is lifted, the side panels 41 are manually installed. Furthermore, the top cover 42 is in a herringbone shape, and the hoisting machine body 51 and the small hoisting machine 8 are both arranged inside the top cover 42, and the wire rope 52 of the hoisting unit 5 passes through the top cover 42 and contacts the directional wheel 53.

[0042] As another specific embodiment, the side panel 41 includes a left side panel, a front side panel, a right side panel and a rear side panel arranged in sequence around the periphery, and the left side panel and the right side panel are both composed of an upper unit panel 43 and a lower unit panel 44, the upper end of the upper unit panel 43 is hinged to the top cover 42, the lower end of the upper unit panel 43 is hinged to the upper end of the lower unit panel 44, and the lower end of the lower unit panel 44 is hinged to the bottom frame 2. By hingedly setting the upper unit panel 43 and the lower unit panel 44, the upper unit panel 43 and the lower unit panel 44 can be made to 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.

[0043] As another specific embodiment, the lower ends of the front side panels and the rear side panels are hinged to the base frame 2. Since the left side panel and the right side panel adopt an automatic unfolding / folding method, when the left side panel and the right side panel are stored, the top cover 42 descends, and the upper unit panel 43 and the lower unit panel 44 fold inward. If the front side panel and the rear side panel are also folded inward at this time, it is easy to interfere with the left side panel and the right side panel. Therefore, the lower ends of the front side panel and the rear side panel are hinged to the base frame 2, and can be retracted first during the folding process, and then the left side panel and the right side panel are automatically folded to avoid interference. Further, the front side panel and the rear side panel can also be lifted by a separate small winch 8 respectively. The small winch 8 is a double wheel, which can realize forward and reverse rotation, thereby realizing the automatic unfolding of the front side panel and the rear side panel, reducing the manual workload. Specifically, the front and rear ends of the top cover are also provided with steering wheels 9.

[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 present embodiment provides a structurally stable automobile gantry crane linked folding roof house, and its working process is as follows:

[0049] 1. Start the hoisting unit 5, and the U-shaped frame 3 rotates in the vertical direction, so that the U-shaped frame 3 is rotated from the horizontal state to the vertical state;

[0050] 2. The steel wire rope 52 lifts the top cover 42, driving the left side panel and the right side panel to transform from the stowed state to the fully extended state;

[0051] 3. Rotate the rope winding device 102 to tighten the tension rope 101 so that the left side plate and the right side plate are close to the U-shaped frame 3;

[0052] 4. Start the small winch 8 to lift the front side plate and the rear side plate.

[0053] When folding the folding room, follow the reverse order.
