[0002] Existing outdoor self-driving enthusiasts and off-road enthusiasts like to travel by car. Due to the limited space inside the car, users cannot rest comfortably in the car. Therefore, a hard-top sleeping cabin installed on the top of the car has appeared on the market. The hard-top sleeping cabin can be used as a bedroom. Normally, the hard-top sleeping cabin is folded and does not affect the operation of the car. When resting, the user unfolds the hard-top sleeping cabin and enters the hard-top sleeping cabin to rest by opening the car's sunroof, thereby meeting user needs.

[0003] However, in the prior art, such as application number CN201821776288.1, titled "Hard-lift Cabin," a triangular roof tent structure is used. The front end of the rectangular roof is hinged to the bottom plate. By opening two supporting cylinders on the side, the rear end of the rectangular roof flips up and opens around the hinge at the front end. A soft canopy is formed on three sides of the rectangular roof by brackets to form a triangular cubic cabin. Disadvantages: ① Due to the triangular shape of the cabin, the interior space of the tent is small. ② After the tent is opened, the space is small due to the cylinders on the side, making it difficult to arrange windows, and the lighting inside the tent is poor.

[0004] Application number: CN202010461370.0, title: A scissor-type rapid lift roof device for vehicles and a vehicle using the device. Scissor-type lifts are arranged on both sides of the tent. Cylinders push the scissor-type lifts to raise the roof, and brackets surround the four sides of the roof to form a rectangular cubic cabin. Disadvantages: ① When the tent is opened, the lifting device is located on the side, making it difficult to arrange windows on the side, resulting in poor lighting inside the tent. ② The soft roof is made of fabric, which provides poor warmth and is easily damaged by sharp objects.

[0009] The door panel is rotatably arranged at the top cover / bottom plate / lifting frame, and the door panel rotates to open or close the inner cavity of the lifting frame;

[0010] The supporting bottom plate is provided with corresponding lifting devices corresponding to the number of folding mechanisms, and the lifting devices are connected to the lower folding parts of the corresponding folding mechanisms. When the lifting devices work, the lower folding parts and the upper folding parts move away from or toward each other, thereby realizing the expansion or closure of the lifting frame;

[0011] When the lifting device drives the lifting frame to unfold, the lifting frame drives the upper side panels and the lower side panels to unfold with each other, and then the door panel rotates to close the inner cavity of the lifting frame. At this time, the top cover, the lifting frame, the upper side panels, the lower side panels, the door panel and the bottom panel form a sleeping cabin in the unfolded state;

[0012] The door panel rotates to open the inner cavity of the lifting frame, and then the lifting device works to drive the lifting frame to close, causing the supporting top plate and the supporting bottom plate to move closer to each other, and at the same time the upper side plate and the lower side plate to move closer to each other, and at the same time the top cover and the bottom plate to move closer to each other. At this time, the top cover, lifting frame, upper side plate, lower side plate, door panel and bottom plate are overlapped to form a closed cabin.

[0013] The user starts the lifting device, and the lifting device drives the lifting frame to unfold. At the same time, the upper side panel and the lower side panel follow the lifting frame to unfold with each other, and the upper side panel and the lower side panel are spliced to form a whole panel. Then the user manually flips the door panel to close the inner cavity of the lifting frame.

[0014] When the hard-lift top cabin is closed, the user manually flips the door panel and moves it towards the top cover, thereby opening the inner cavity of the lifting frame. Then the user starts the lifting device, which drives the lifting frame to close, causing the supporting top plate and the supporting bottom plate to move closer to each other, and the upper side plate and the lower side plate to move closer to each other. At the same time, the top cover and the bottom plate are overlapped to form a cabin in a closed state. The operation is simple, and the height of the cabin in the closed state is relatively small. The cabin in the closed state is set on the top of the car, which has little effect on the height of the car. The car can travel normally on height-restricted roads, meeting user needs.

[0019] When the push-up pin slides to the front end of the guide slide, the upper folding part and the lower folding part move closer to each other, and when the push-up pin slides to the rear end of the guide slide, the upper folding part and the lower folding part unfold with each other.

[0020] The pushing pin passes through the guide slide and slides along the guide slide. When the electric push rod pushes the slider forward, the pushing pin slides from the front end of the guide slide to the rear end of the guide slide, and the upper folding part and the lower folding part unfold with each other, thereby unfolding the lifting frame. When the electric push rod pushes the slider backward, the pushing pin slides from the rear end of the guide slide to the front end of the guide slide, and the upper folding part and the lower folding part move closer to each other, thereby folding the lifting frame. The principle is simple and the guide slide limits the sliding position of the pushing pin, thereby avoiding offset of the upper folding part and the lower folding part, and greatly improving safety.

[0021] Furthermore, a transverse limit groove is opened on the side wall of the slide, and a limit column is set at the position of the slide corresponding to the transverse limit groove. The limit column is inserted into the transverse limit groove. The transverse limit groove limits the sliding distance of the limit column, thereby limiting the sliding distance of the slide.

[0022] The limiting column of the slider is inserted into the transverse limiting groove of the slide groove. The transverse limiting groove limits the sliding distance of the limiting column, thereby limiting the sliding distance of the slider, avoiding sliding deviation of the slider, and greatly improving the stability of the lifting frame.

At the same time, the lower outer folding rod follows the lower inner folding rod to rotate and unfold. As the connecting piece is lifted, the connecting piece drives the pull rod assembly to rotate and unfold. Since the pull rod assembly and the upper inner folding rod are fixedly connected, the pull rod assembly drives the upper inner folding rod to rotate and unfold. At the same time, the upper outer folding rod also follows the upper inner folding rod to rotate and unfold, so that the upper outer folding rod and the upper inner folding rod jointly lift the support top plate to move up. , and finally the lifting frame is unfolded. Similarly, the electric push rod drives the slider to move backward, and the push-up pin moves to the front end of the curved guide slide. The push-up pin drives the lower inner folding rod to rotate and fold. The lower inner folding rod drives the connecting part to move downward. At the same time, the lower outer folding rod follows the lower inner folding rod to rotate and fold. As the pull rod assembly drives the lower inner folding rod to rotate and fold, the upper outer folding rod also follows the upper inner folding rod to rotate and fold, causing the height of the supporting top plate to gradually decrease until the supporting top plate and the supporting bottom plate are close to each other, realizing the folding of the lifting frame.

At the same time, the top cover and the bottom plate are overlapped to form a cabin in a closed state. The operation is simple, and the height of the cabin in the closed state is relatively small. The cabin in the closed state is arranged on the top of the car, which has little effect on the height of the car. The car can travel normally on height-restricted roads, meeting user needs.

[0069] In the present invention, the electric push rod drives the slider to move forward, forcing the push-up pin to move to the rear end of the curved guide slide, and the push-up pin drives the lower inner folding rod to rotate and unfold, and the lower inner folding rod lifts the connecting piece upward, and at the same time, the lower outer folding rod follows the lower inner folding rod to rotate and unfold, and as the connecting piece is lifted, the connecting piece drives the pull rod assembly to rotate and unfold, and since the pull rod assembly and the upper inner folding rod are fixedly connected, the pull rod assembly drives the upper inner folding rod to rotate and unfold, and at the same time, the upper outer folding rod also follows the upper inner folding rod to rotate and unfold, so that the upper outer folding rod and the upper inner folding rod jointly lift the supporting top plate. The lifting frame is unfolded by moving the slider backward and the lifting pin moves to the front end of the curved guide slide. The lifting pin drives the lower inner folding rod to rotate and fold. The lower inner folding rod drives the connecting part to move downward. At the same time, the lower outer folding rod follows the lower inner folding rod to rotate and fold. As the pull rod assembly drives the lower inner folding rod to rotate and fold, the upper outer folding rod also follows the upper inner folding rod to rotate and fold, causing the height of the supporting top plate to gradually decrease until the supporting top plate and the supporting bottom plate are close to each other, and the lifting frame is folded. The principle is simple and reliable.

[0070] According to the present invention, when the hard-lifting top sleeping cabin is unfolded, the upper side panel and the lower side panel are unfolded relative to each other, the L-shaped notch of the upper side panel is inserted into the L-shaped notch of the lower side panel, and at the same time, the waterproof foam is squeezed against each other, and the upper side panel and the lower side panel form a whole panel. The waterproof foam seals the connection gap between the upper side panel and the lower side panel, thereby greatly improving the waterproof effect of the hard-lifting top sleeping cabin.

[0071] The upper side of the upper side panel is placed in the upper mounting groove of the top cover, and at the same time, the waterproof foam seals the gap between the upper side panel and the upper mounting groove, thereby improving the waterproof effect between the upper side panel and the top cover; the lower side of the lower side panel is placed in the lower mounting groove of the bottom plate, and at the same time, the waterproof foam seals the gap between the lower side panel and the lower mounting groove, thereby improving the waterproof effect between the lower side panel and the bottom plate, thereby improving the waterproof effect of the hardtop sleeping cabin.

[0097] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0098] Example, combined with Figures 1 to 23As shown, a hard-lifting top sleeping cabin for a car includes a roof 1, a bottom plate 2, a lifting frame 3, a door panel 4, an upper side panel 51 and a lower side panel 52. The lifting frame 3 includes a supporting top plate 31, a supporting bottom plate 32, a folding mechanism 6 and a lifting device 7. The folding mechanism 6 includes an upper folding portion 61 and a lower folding portion 62, and the upper folding portion 61 and the lower folding portion 62 are movably connected. The folding mechanism 6 is arranged between the supporting top plate 31 and the supporting bottom plate 32, the upper folding portion 61 is connected to the supporting top plate 31, and the lower folding portion 62 is connected to the supporting bottom plate 32.

[0099] The top cover 1 and the bottom plate 2 are arranged one above and one below, the lifting frame 3 is arranged between the top cover 1 and the bottom plate 2 and are respectively located on the front and rear sides of the bottom plate 2, and an installation area is formed between the folding mechanism 6 of the lifting frame 3 and the folding mechanism 6 of another lifting frame 3, the upper side plate 51 is located in the installation area and connected to the upper folding part 61, and the upper side plate 51 follows the movement of the upper folding part 61, and the lower side plate 52 is located in the installation area and connected to the lower folding part 62, and the lower side plate 52 follows the movement of the lower folding part 62.

[0100] The door panel 4 is rotatably mounted on the top cover 1 , and the door panel 4 rotates to open or close the inner cavity of the lifting frame 3 .

[0101] The supporting base plate 32 is provided with corresponding lifting devices 7 corresponding to the number of folding mechanisms 6. The lifting devices 7 are connected to the lower folding parts 62 of the corresponding folding mechanisms 6. The lifting devices 7 drive the lower folding parts 62 and the upper folding parts 61 to move away from or approach each other, thereby realizing the expansion or closure of the lifting frame 3.

[0102] When the lifting device 7 drives the lifting frame 3 to expand, the lifting frame 3 drives the upper side panel 51 and the lower side panel 52 to expand with each other, and then the door panel 4 rotates to close the inner cavity of the lifting frame 3. At this time, the top cover 1, the lifting frame 3, the upper side panel 51, the lower side panel 52, the door panel 4 and the bottom panel 2 form a bedroom cabin in the expanded state.

[0103] The door panel 4 rotates to open the inner cavity of the lifting frame 3, and then the lifting device 7 works to drive the lifting frame 3 to close, causing the supporting top plate 31 and the supporting bottom plate 32 to move closer to each other, and at the same time the upper side plate 51 and the lower side plate 52 move closer to each other, and at the same time the top cover 1 and the bottom plate 2 move closer to each other. At this time, the top cover 1, the lifting frame 3, the upper side plate 51, the lower side plate 52, the door panel 4 and the bottom plate 2 are overlapped to form a closed cabin.

[0104] The user starts the lifting device 7, and the lifting device 7 drives the lifting frame 3 to unfold. At the same time, the upper side panel 51 and the lower side panel 52 follow the lifting frame 3 to unfold with each other, and the upper side panel 51 and the lower side panel 52 are spliced to form a whole panel 5. Then the user manually flips the door panel 4 to close the inner cavity of the lifting frame 3. The top cover 1, the upper side panel 51, the lower side panel 52, the door panel 4 and the bottom panel 2 form a hard-lift top sleeping cabin. The user can lie down in the hard-lift top sleeping cabin to rest. The unfolding process of the hard-lift top sleeping cabin is simple, and the lifting device 7 will not block the outside of the hard-lift top sleeping cabin, so that the field of view of the hard-lift top sleeping cabin is wider, and it does not affect the opening of windows on the side walls of the hard-lift top sleeping cabin, which greatly improves the practicality of the hard-lift top sleeping cabin.

[0105] When the hard-lifting top cabin is closed, the user manually flips the door panel 4 and moves it toward the top cover 1, thereby opening the inner cavity of the lifting frame 3. Then the user starts the lifting device 7, and the lifting device 7 drives the lifting frame 3 to close, causing the supporting top plate 31 and the supporting bottom plate 32 to move closer to each other, and at the same time the upper side plate 51 and the lower side plate 52 move closer to each other, and at the same time the top cover 1 and the bottom plate 2 move closer to each other. At this time, the top cover 1, the lifting frame 3, the upper side plate 51, the lower side plate 52, the door panel 4 and the bottom plate 2 overlap to form a cabin in a closed state. The operation is simple, and the height of the cabin in the closed state is relatively small. The cabin in the closed state is set on the top of the car, which has little effect on the height of the car. The car can travel normally on height-restricted roads, meeting user needs.

[0106] Furthermore, the lifting frame 3 includes two folding mechanisms 6 and two lifting devices 7. The two folding mechanisms 6 are located between the support top plate 31 and the support bottom plate 32. The two folding mechanisms 6 stand opposite to each other. The two lifting devices 7 are arranged on the support bottom plate 32. The two lifting devices 7 stand opposite to each other. The two lifting devices 7 are respectively connected to the corresponding folding mechanisms 6.

[0107] The one lifting device 7 drives one folding mechanism 6 to move, and the two lifting devices 7 drive the two folding mechanisms 6 to move up and down at the same time, thereby realizing the unfolding and folding of the lifting frame 3. The principle is simple and reliable.

[0108] Furthermore, the lifting device 7 includes an electric push rod 71 and a slider 72. The support base plate 32 is provided with a slide groove 321 along its width direction. The electric push rod 71 is fixed in the slide groove 321. The slider 72 is arranged in the slide groove 321 in a sliding manner. The pushing part of the electric push rod 71 is connected to the slider 72. The electric push rod 71 drives the slider 72 to slide along the slide groove 321. The slider 72 is provided with a guide slide 721. The lower folding part 62 is provided with a push-up pin 623. The push-up pin 623 passes through the guide slide 721 and slides along the guide slide 721.

[0109] When the pushing pin 623 slides to the front end of the guide slide 721, the upper folding part 61 and the lower folding part 62 move closer to each other. When the pushing pin 623 slides to the rear end of the guide slide 721, the upper folding part 61 and the lower folding part 62 unfold to each other.

[0110] The pushing pin 623 passes through the guide slide 721 and slides along the guide slide 721. When the electric push rod 71 pushes the slider 72 to move forward, the pushing pin 623 slides from the front end of the guide slide 721 to the rear end of the guide slide 721, and the upper folding part 61 and the lower folding part 62 unfold with each other, thereby unfolding the lifting frame 3. When the electric push rod 71 pushes the slider 72 to move backward, the pushing pin 623 slides from the rear end of the guide slide 721 to the front end of the guide slide 721, and the upper folding part 61 and the lower folding part 62 move closer to each other, thereby folding the lifting frame 3. The principle is simple and the guide slide 721 limits the sliding position of the pushing pin 623, thereby avoiding deviation of the upper folding part 61 and the lower folding part 62, thereby greatly improving safety.

[0111] Furthermore, a transverse limit groove 3211 is opened on the side wall of the slide groove 321, and a limit column 722 is set at the position of the slider 72 corresponding to the transverse limit groove 3211. The limit column 722 is inserted into the transverse limit groove 3211, and the transverse limit groove 3211 limits the sliding distance of the limit column 722, thereby limiting the sliding distance of the slider 72.

[0112] The limiting column 722 of the slider 72 is inserted into the transverse limiting groove 3211 of the slide groove 321. The transverse limiting groove 3211 limits the sliding distance of the limiting column 722, thereby limiting the sliding distance of the slider 72, avoiding the sliding deviation of the slider 72, and greatly improving the stability of the lifting frame 3.

[0113] Furthermore, the folding mechanism 6 also includes a pull rod assembly 63 and a connecting member 64, the upper folding part 61 includes two upper outer folding rods 611 and two upper inner folding rods 612, the lower folding part 62 includes two lower outer folding rods 621 and two lower inner folding rods 622, and the pull rod assembly 63 includes an upper pull rod 631, a lower pull rod 632 and a pull rod arm 633.

[0114] The upper end of the upper outer folding rod 611 is connected to the supporting top plate 31 in a rotatable manner, and the lower end of the upper outer folding rod 611 is connected to the connecting member 64 in a rotatable manner.

[0115] The upper end of the upper inner folding rod 612 is connected to the supporting top plate 31 in a rotatable manner, and the lower end of the upper inner folding rod 612 is connected to the connecting member 64 in a rotatable manner.

[0116] The upper end of the lower outer folding rod 621 is connected to the connecting member 64 in a rotatable manner, and the lower end of the lower outer folding rod 621 is connected to the supporting base plate 32 in a rotatable manner.

[0117] The upper end of the lower inner folding rod 622 is connected to the connecting member 64 in a rotatable manner, and the lower end of the lower inner folding rod 622 is connected to the supporting base plate 32 in a rotatable manner.

[0118] The upper end of the upper pull rod 631 is connected to the pull rod arm 633, the lower end of the upper pull rod 631 is connected to the upper end of the lower pull rod 632, and the lower end of the lower pull rod 632 is connected to the slider 72 in a rotatable manner. The pull rod arm 633 is located between the upper inner folding rod 612, the pull rod arm 633 and the upper inner folding rod 612 are fixedly connected, and the pull rod assembly 63 rotates to push the upper folding part 61 to rotate.

[0119] The top of the slider 72 is provided with mutually opposing plates 723, and the plate 723 has a curved guide slide 721 that bends from left to right and from bottom to top. The lower inner folding rod 622 is provided with the push-up pin 623, and the push-up pin 623 is inserted into the corresponding curved guide slide 721.

[0120] The electric push rod 71 drives the slider 72 to move forward, forcing the push pin 623 to move to the rear end of the curved guide slide 721, and the push pin 623 drives the lower inner folding rod 622 to rotate and unfold, and the lower inner folding rod 622 lifts the connecting piece 64 upward, and at the same time, the lower outer folding rod 621 follows the lower inner folding rod 622 to rotate and unfold. As the connecting piece 64 is lifted, the connecting piece 64 drives the pull rod assembly 63 to rotate and unfold. Since the pull rod assembly 63 and the upper inner folding rod 612 are fixedly connected, the pull rod assembly 63 drives the upper inner folding rod 612 to rotate and unfold, and at the same time, the upper outer folding rod 611 also follows the upper inner folding rod 612 to rotate and unfold, so that the upper outer folding rod 611 and the upper inner folding rod 612 lift the support together. The top plate 31 moves up, and finally the lifting frame 3 is unfolded. Similarly, the electric push rod 71 drives the slider 72 to move backward, and the pushing pin 623 moves to the front end of the curved guide slide 721. The pushing pin 623 drives the lower inner folding rod 622 to rotate and fold. The lower inner folding rod 622 drives the connecting part 64 to move down. At the same time, the lower outer folding rod 621 follows the lower inner folding rod 622 to rotate and fold. As the pull rod assembly 63 drives the lower inner folding rod 622 to rotate and fold, the upper outer folding rod 611 also follows the upper inner folding rod 612 to rotate and fold, causing the height of the supporting top plate 31 to gradually decrease until the supporting top plate 31 and the supporting bottom plate 32 are close to each other, and the lifting frame 3 is folded. The principle is simple and reliable.

When the upper side panel 51 and the lower side panel 52 are unfolded to each other, the L-shaped notch 521 of the upper side panel 51 and the L-shaped notch 521 of the lower side panel 52 cooperate, and at the same time, the waterproof foam 8 and the waterproof foam 8 squeeze each other, and the upper side panel 51 and the lower side panel 52 are connected to the whole panel 5.

At the same time, the waterproof foam 8 and the waterproof foam 8 are squeezed against each other, and the upper side panel 51 and the lower side panel 52 form a whole panel 5. The waterproof foam 8 seals the connection gap between the upper side panel 51 and the lower side panel 52, thereby greatly improving the waterproof effect of the hard-lifting top cabin.

In addition, reinforcing ribs are added to the bottom plate 2, and the load-bearing effect of the bottom plate 2 is better. When the user lies in the hard-lifting top sleeping cabin, if the user needs to adjust the position of the hard-lifting top sleeping cabin, the user controls the rotating base through the remote control, and the rotating base drives the hard-lifting top sleeping cabin to rotate, and adjusts the position of the hard-lifting top sleeping cabin to meet the user's needs.

[0152] As another embodiment:

[0153] Furthermore, it also includes supporting lifting feet (not shown in the figure), and the base plate 2 has a supporting lifting foot installation opening reserved therein, and the supporting lifting feet are detachably connected to the supporting lifting foot installation opening, and the supporting lifting feet are used to support the base plate 2 upwards.

[0154] The hard-lifting top sleeping cabin can be placed on the ground for use. When the user goes camping outdoors, the user disassembles the hard-lifting top sleeping cabin and installs the supporting lifting feet on the supporting lifting foot installation openings. The user adjusts the height of the hard-lifting top sleeping cabin from the ground by adjusting the height of the supporting lifting feet, thereby allowing the hard-lifting top sleeping cabin to be used on different types of ground, thereby improving the applicability of the hard-lifting top sleeping cabin.

[0155] After the hard-lifting top cabin is unfolded, the user can install the supporting lifting feet at the supporting lifting installation port at the bottom, with the lower end of the supporting lifting feet resting on the ground, and the upper end of the supporting lifting feet supporting the bottom plate 2 upward, so that the top of the car and the supporting lifting feet jointly support the hard-lifting top cabin, share the load on the top of the car, and improve the safety of the hard-lifting top cabin. Furthermore, when the hard-lifting top cabin rotates, the supporting lifting feet support the hard-lifting top cabin, share the load on the top of the car, and improve the safety of the hard-lifting top cabin.

When the life monitoring device detects that there are living things in the cabin, the control panel controls the electric push rod 71 to maintain the expanded cabin state.

[0158] The hard-lifting top sleeping cabin is provided with a life monitoring device. When the life monitoring device detects the presence of living organisms in the hard-lifting top sleeping cabin, the control motor controls the electric push rod 71 to maintain the unfolded state of the hard-lifting top sleeping cabin, thereby preventing the hard-lifting top sleeping cabin from folding and crushing the user, thereby greatly improving the safety of the hard-lifting top sleeping cabin.

[0159] Working principle:

[0160] Lifting frame 3 unfolded:

[0161] The electric push rod 71 drives the slider 72 to move forward, forcing the pushing pin 623 to move to the rear end of the guide slide 721, and the pushing pin 623 drives the lower inner folding rod 622 to rotate and unfold, and the lower inner folding rod 622 lifts the connecting piece 64 upward, and at the same time, the lower outer folding rod 621 follows the lower inner folding rod 622 to rotate and unfold, as the connecting piece 64 is lifted, the connecting piece 64 drives the pull rod assembly 63 to rotate and unfold, because the pull rod assembly 63 and the upper inner folding rod 612 are fixedly connected, the pull rod assembly 63 drives the upper inner folding rod 612 to rotate and unfold, and at the same time, the upper outer folding rod 611 also follows the upper inner folding rod 612 to rotate and unfold, so that the upper outer folding rod 611 and the upper inner folding rod 612 jointly lift the support top plate 31 upward, causing the distance between the support top plate 31 and the support bottom plate 32 to gradually increase, thereby realizing the unfolding of the lifting frame 3.

[0162] Hard-lift top cabin unfolded:

[0163] After the lifting frame 3 is unfolded, the upper side panel 51 and the lower side panel 52 follow the lifting frame 3 to unfold to each other, and the upper side panel 51 and the lower side panel 52 are spliced to form a whole panel 5. Then the user manually flips the door panel 4 to close the inner cavity of the lifting frame 3. The top cover 1, the upper side panel 51, the lower side panel 52, the door panel 4 and the bottom panel 2 form a hard-lifting top sleeping cabin. The user can lie down in the hard-lifting top sleeping cabin to rest. The unfolding process of the hard-lifting top sleeping cabin is simple, and the lifting device 7 will not block the outside of the hard-lifting top sleeping cabin, so that the field of view of the hard-lifting top sleeping cabin is wider, and it does not affect the opening of windows on the side walls of the hard-lifting top sleeping cabin, which greatly improves the practicality of the hard-lifting top sleeping cabin.

[0164] Lifting frame 3 folds:

[0165] The electric push rod 71 drives the slider 72 to move backward, and the pushing pin 623 moves to the front end of the guide slide 721. The pushing pin 623 drives the lower inner folding rod 622 to rotate and fold. The lower inner folding rod 622 drives the connecting piece 64 to move downward. At the same time, the lower outer folding rod 621 follows the lower inner folding rod 622 to rotate and fold. As the pull rod assembly 63 drives the lower inner folding rod 622 to rotate and fold, the upper outer folding rod 611 also follows the upper inner folding rod 612 to rotate and fold, causing the height of the support top plate 31 to gradually decrease until the support top plate 31 and the support bottom plate 32 are close to each other, and the lifting frame 3 is folded.

[0166] Folding of the hard-lifting cabin: the user first manually flips the door panel 4 and moves it towards the top cover 1, thereby opening the inner cavity of the lifting frame 3, and then closes the lifting frame 3, causing the supporting top plate 31 and the supporting bottom plate 32 to move closer to each other, and at the same time the upper side panel 51 and the lower side panel 52 move closer to each other, and at the same time the top cover 1 and the bottom plate 2 move closer to each other. At this time, the top cover 1, the lifting frame 3, the upper side panel 51, the lower side panel 52, the door panel 4 and the bottom plate 2 overlap to form a cabin in a closed state. The operation is simple, and the height of the cabin in the closed state is relatively small. The cabin in the closed state is set on the top of the car, which has little effect on the height of the car. The car can travel normally on height-restricted roads, meeting user needs.
