Description

Technical Field

[0001] The utility model relates to the field of outdoor automobile products, in particular to a stably unfolded automobile gantry crane linked folding roof-lifting board house. Background Art

[0002] In order to realize the function of converting an ordinary car into a motorhome and meet the needs of outdoor camping, the Chinese utility model patent "CN220639661 U-A kind of automobile gantry crane linked folding and lifting roof board house" adopts "a base frame is arranged on the top of the vehicle body, and a U-shaped frame is hinged on the base frame, and the two ends of the U-shaped frame are respectively hinged on the two sides of the base frame; the base frame is also provided with a folding plate assembly (including side panels arranged on all sides and a top cover arranged on the top), and the folding plate assembly and the U-shaped frame are connected through a winch unit"; its working process is: release the safety buckle, start the winch unit, the U-shaped frame rotates in the vertical direction, and the U-shaped frame rotates from a horizontal state to a vertical state; stop the winch unit, and use a hook to fix the U-shaped frame; start the winch unit again, the wire rope lifts the top cover, and drives the left and right panels from the storage state to the fully unfolded state; start the small winch body to lift the front side panel and the rear side panel.

[0003] In the above scheme, there is only one steel wire rope between the top of the U-frame and the top cover.

On the other hand, the safety factor of one steel wire rope is not high, that is, if the steel wire rope breaks when the top cover is lifted, the top cover will drop rapidly and hit the base frame, causing damage to components and measurements.

[0004] Therefore, a new solution is needed to solve the problems of low stability and low safety factor during deployment. Utility Model Content

DETAILED DESCRIPTION

[0028] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0029] Any feature disclosed in this specification, unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0030] Example 1

[0031] like Figure 1-Figure 8 As shown, a stably unfolded automobile gantry crane-linked folding and lifting roof panel house comprises a base frame 2 and a U-shaped frame 3 which can be fixed on a vehicle body 1. The base frame 2 can be fixedly connected to the vehicle body 1 by welding, or can be detachably connected to the vehicle body 1 by bolts; the base frame 2 passes through the U-shaped frame 3, and the U-shaped frame 3 is hinged to the base frame 2 so that the U-shaped frame 3 can be converted between inverted and upright. When the folding plate assembly 4 is unfolded, the U-shaped frame 3 first changes from an inverted state to an upright state, forming a gantry crane to provide support for the unfolding of the folding plate assembly 4; after the folding plate assembly 4 is folded, the U-shaped frame 3 changes from an upright state to an inverted state. The base frame 2 is provided with a folding plate assembly 4 which can be unfolded and is located inside the U-shaped frame 3. When the folding plate assembly 4 is unfolded, a board room space is formed inside. There are multiple guide members on the top of the U-shaped frame 3. A winch unit is provided on the folding plate assembly 4. The winch unit has multiple strands of steel wire ropes 52 and a winch body 5 for winding and releasing the steel wire ropes 52. There are two strands of steel wire ropes 52 that pass through some of the guide members respectively and are fixedly connected to both sides of the folding plate assembly 4.

[0032] In this embodiment, the process of unfolding the folding plate assembly 4 is as follows:

[0033] S1: Start the hoist body 5 of the hoisting unit, and the U-shaped frame 3 rotates so that the U-shaped frame 3 changes from an inverted state to an upright state;

[0034] S2: Stop the winch unit and lock the U-shaped frame 3;

[0035] S3: The winch body 5 of the winch assembly is started again, and all the wire ropes 52 are wound up at the same time, so that the wire ropes 52 lift the top cover 42 of the folding plate assembly 4 to unfold the folding plate assembly 4, that is, drive the left plate and the right plate to be transformed from the folded state to the fully unfolded state.

[0036] It should be noted that the folding process of the folding plate assembly 4 is opposite to the unfolding process, which will not be described in detail here.

[0037] like Figure 6 As shown, in this embodiment, the guide member can be a fixed pulley structure; or, the guide member can be composed of a plurality of rotating roller groups, each of which has two rotating rollers 8 that can rotate about its own axis, and there is a gap between the rotating rollers 8 for the wire rope 52 to pass through, so as to guide the wire rope 52 and constrain the wire rope 52, thereby preventing the wire rope 52 from escaping from the wire rope 52 guide member when in a relaxed state.

[0038] In this embodiment, multiple strands of steel wire ropes 52 are provided to connect the U-shaped frame 3 and the folding assembly, and two strands of steel wire ropes 52 are fixedly connected to the two sides of the folding plate assembly 4, so that when the folding plate assembly 4 is lifted and unfolded by the steel wire ropes 52, there is a force point with a transverse span, thereby avoiding lateral shaking when the top cover 42 is lifted, and effectively improving the stability of the unfolding of the board house; the multiple strands of steel wire ropes 52 effectively improve the safety factor when the folding plate assembly 4 is lifted and unfolded, that is, even if one or more steel wires are broken, there are other steel wires to provide traction so that the folding plate assembly 4 continues to unfold.

[0039] Example 2

[0040] Based on Example 1, a specific implementation method that can be implemented is further proposed.

[0041] A feasible implementation manner, three guides are arranged on the top of the U-shaped frame 3, one of which is located at the middle position of the top of the U-shaped frame 3 as a guide a31, and the other two are located at both sides of the U-shaped frame 3 as guides b32; the hoisting unit has two steel wire ropes 52 and a hoisting unit body 5 for simultaneously winding and releasing the two steel wire ropes 52, and the two steel wire ropes 52 pass through the guide located in the middle position and then pass through the guides located on both sides. Specifically, there are rotating roller groups as described in Example 1 on both sides and the bottom of the guide a31, and the guide b32 is the fixed pulley described in Example 1 or there is a group of rotating roller groups; the two steel wire ropes 52 pass through the rotating roller group located at the bottom of the guide a31 and then pass through the rotating roller groups located at both sides of the guide a31, and then go around or pass through the guide b32 and connect to the top cover 42 on the top of the folding plate assembly 4, and the connection points are located on both sides of the top cover 42, that is, there is a horizontal span between the two connection points.

[0042] It should be noted that, based on the above-mentioned embodiment, multiple strands of steel wire ropes 52 and guide members can be added according to actual conditions, and a winch body 5 for winding and releasing the steel wire ropes 52 can be adaptively added.

[0043] A feasible implementation manner, the output shaft of the winch body 5 is coaxially fixedly connected with a winding and releasing roller 54, and two wire grooves 51 are provided on the winding and releasing roller 54, and two steel wire ropes 52 are respectively wound in the two steel wire grooves 51, which not only effectively realizes the simultaneous winding and releasing of the two steel wire ropes 52, but also effectively avoids the two steel wire ropes 52 from being entangled with each other, thereby ensuring that the steel wire ropes 52 are stably and effectively performing traction movement.

[0044] Example 3

[0045] Based on any one of the implementations in Examples 1-2, a feasible implementation is further proposed.

[0046] A feasible implementation method, since the folding plate assembly 4 needs to be folded and stored when not in use, and the U-shaped frame 3 is hinged on the bottom frame 2, the height of the storage state can be minimized when the U-shaped frame 33 is inverted, so that the device meets the requirements of driving safety traffic regulations. In order to ensure that the U-shaped frame 3 can smoothly transform from the inverted state to the upright state, a rotating wheel 6 for steering the steel wire rope 52 is provided at the front or rear end of the folding plate assembly 4; when the U-shaped frame 3 is inverted, the U-shaped frame 3 surrounds the bottom frame 2; the number of rotating wheels 6 matches the number of guides or the number of steel wire ropes 52 between the U-shaped frame 3 and the folding plate assembly 4, and the steel wire rope 52 is placed on the rotating wheel 6. Specifically, on the one hand, the wire rope 52 can be steered by the rotating wheel 6 to prevent the wire rope 52 from rubbing against the folding plate assembly 4; on the other hand, the design of the rotating wheel 6 enables the wire rope 52 to first lift the U-shaped frame 3 upward when winding, so that the U-shaped frame 3 begins to transform into an upright state; as the wire rope 52 continues to be wound, the wire rope 52 will rotate with the U-shaped frame 3 (at this time, only a small length of the wire rope 52 is wound), which can ensure that the U-shaped frame 3 can smoothly transform from an inverted state to an upright state.

[0047] Furthermore, in order to reduce the rotation speed of the U-shaped frame 3 when it is transformed from inverted to upright, and to prevent friction between the wire rope 52 and the top cover 42 of the folding plate assembly 4 when it is wound, a positioning wheel 53 can be set above the folding plate assembly 4; specifically, the positioning wheel 53 is equivalent to a fixed pulley, and when the wire rope 52 is wound, the fixed pulley always supports the wire rope 52 so that the wire rope 52 is in a tensioned state; and the winding length of the wire rope 52 is converted into an arc length of nearly 90° on the fixed pulley, which effectively increases the winding length of the wire rope 52 compared to when there is no fixed pulley, thereby reducing the rotation speed of the U-shaped frame 3, and further effectively reducing the shaking that occurs when the U-shaped frame 3 is transformed into an upright position.

[0048] Example 4

[0049] Based on any one of the implementations in Examples 1-3, a feasible implementation is further proposed.

[0050] The U-shaped frame 3 serves as a support for lifting and unfolding the folding plate assembly 4, ensuring that the U-shaped frame 3 is locked in an upright state to prevent the U-shaped frame 3 from shaking when the stacked plate assembly is lifted; for this purpose, a locking mechanism 7 for locking the U-shaped frame 3 in an upright state is provided between the base frame 2 and the U-shaped frame 3.

[0051] In this embodiment, the following feasible implementations are proposed regarding the locking mechanism.

[0052] like Figure 2 , Figure 4As shown, 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.

[0053] like Figure 2 , Figure 5-Figure 6 As shown, 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 remain in contact with each other, so that the U-shaped frame 3 can be stably maintained in the 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 transformed from inverted to upright).

[0054] 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.

[0055] 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.

[0056] 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 5 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.

[0057] Example 5

[0058] Based on any one of the implementations in Examples 1-4, a feasible implementation is further proposed.

[0059] 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 is in a stable unfolded state and is fully unfolded. At the same time, the position of the U-shaped frame 3 can be fixed, thereby improving the supporting stability of the U-shaped frame 3.

[0060] Regarding the fastening connection device 10, this embodiment proposes the following several feasible implementation methods.

[0061] In the first 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. The tensioning rope 101 is used to tightly attach and lock the U-shaped frame 3 and the side panel 41 of the folding plate assembly 4 after unfolding (the rope winding device 102 locks the tensioning rope 101).

[0062] In the second embodiment, the fastening connection device 10 includes a tensioning rope 101, 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 supported by 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. The tensioning rope 101 is supported by the U-shaped frame 3, so that the tensioning rope 101 is subjected to tensioning force after being tightened, and the tensioning force reacts to the U-shaped frame 3, so that the U-shaped frame 3 and the side panel 41 of the folding plate assembly 4 after unfolding are tightly attached and locked (the rope winding device 102 locks the tensioning rope 101).

[0063] In a feasible implementation, 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 101 from causing wear to the U-shaped frame 3, and can guide the tension rope 101. Further, the rope passing pulley is a frame-shaped four-way pulley or a component with the same structure as the guide, and the tension rope 101 passes through the frame.

[0064] A feasible implementation method, such as 2- Figure 7As shown, the rope winding device 102 includes a rotating shaft 1021, and the rotating shaft 1021 is arranged on the U-shaped frame 3 or the base 2 through a base 1022. A ratchet 1023 is provided on one side of the rotating shaft 1021, and a pawl 1024 matching the ratchet 1023 is hinged on the base 1022; a rotating part 1025 is provided on the other side of the rotating shaft 1021; the rotating part 1025 can obtain rotational power from manual or motor sources, so as to reel in or release the tensioning rope 101; one-way transmission can be achieved through the ratchet 1023 and the pawl 1024, allowing the tensioning rope 101 to be freely reeled in, and being locked when releasing the tensioning rope 101, and no additional force is required to maintain the locked state; and when loosening, the pawl 1024 only needs to be pushed open to release the lock.

[0065] Example 6

[0066] Based on any one of the implementations in Examples 1-5, a feasible specific implementation is further proposed.

[0067] In a feasible specific implementation manner, the folding plate assembly 4 includes side plates 41 arranged on all sides and a top cover 42 arranged on the top, and the hoisting unit 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.

[0068] In a feasible implementation manner, the side panel 41 is hinged to the top cover 42, and when the folding plate assembly 4 is unfolded, the side panel 41 is transformed from being inverted to being upright; of course, the side panel 41 can be detachably connected to the top cover 42, and after lifting the top cover 42, the side panel 41 can be installed manually.

[0069] In a feasible implementation manner, the top cover 42 is in a herringbone shape, the hoist body 5 is arranged inside the top cover 42, and the wire rope 52 of the hoist assembly passes through the top cover 42 and contacts the directional wheel.

[0070] A feasible implementation manner, the side panel 41 includes a left side panel, a front side panel, a right side panel and a rear side panel which are sequentially arranged around, the left side panel and the right side panel are both composed of an upper unit panel 44 and a lower unit panel 43, the upper end of the upper unit panel 44 is hinged to the top cover 42, the lower end of the upper unit panel 44 is hinged to the upper end of the lower unit panel 43, and the lower end of the lower unit panel 43 is hinged to the bottom frame 2; by means of the hinged upper unit panel 44 and the lower unit panel 43, the upper unit panel 44 and the lower unit panel 43 can be extended outward while maintaining the connection with the top cover 42 and the bottom frame 2, and no manual operation is required during the entire unfolding process, which facilitates installation.

[0071] A feasible implementation manner is that the lower ends of the front side panels and the rear side panels are hinged to the bottom frame 2. Since the left side panel and the right side panel adopt an automatic unfolding / folding mode, when the left side panel and the right side panel are stored, the top cover 42 is lowered, and the upper unit panel 44 and the lower unit panel 43 are folded 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 bottom 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 separate small winches, which are installed inside the top cover 42; the small winch 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 42 are also provided with steering wheels 9, which guide the steel wire rope 52 between the small winch and the front side panel and the rear side panel.

[0072] As another specific embodiment, a table top is hinged on the front side panel and / or the rear side panel, and table legs are hinged on the table top; the foldable table top can be conveniently used during camping.

[0073] 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.

[0074] 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.

[0075] As another specific embodiment, a solar panel is also provided above the folding plate assembly 4 to provide power for the winch unit and activities within the vehicle.

[0076] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
