In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] Combination Figures 1 to 10 As shown, the present embodiment provides a car roof lifting device, comprising a car body 1, a top cover assembly 2 slidably connected to the side wall of the car body 1, a lifting assembly 3 for driving the top cover assembly 2 to move along the height direction of the car body 1, and a flap 4 cooperating with the notch 221 in the top cover assembly 2. The car roof lifting device designed with this structure can not only realize the automatic retraction and extension of the flap 4, but also can form a sealed space when the top cover assembly 2 is unfolded through the cooperation and separation of the flap 4 and the notch 221, and will not block the opposite side walls of the car body 1 after being folded; preferably, the above-mentioned lifting assembly 3 is configured as a lifting cylinder or an electric push rod, and the mounting position of the lifting assembly 3 is provided with a sealing member for sealing the top cover assembly 2 and the car body 1. The specific configuration of the sealing member is more commonly used in the relevant technology and will not be described in detail here.

[0040] Specifically, the top of the above-mentioned box body 1 is provided with an opening, and the top cover assembly 2 is covered at the upper end of the opening and is slidably connected with the side wall of the box body 1. Preferably, the top cover assembly 2 includes a top cover 21, and long side walls and short side walls 23 arranged around the top cover 21 and arranged opposite to each other. In addition, in order to cooperate with the retraction and extension of the flap 4, a slide rail 24 is horizontally arranged on the inner side of the two short side walls 23, and the two long side walls are provided with notches 221 that match the corresponding flap 4.

[0041] Furthermore, the flap 4 is hinged to the open end of the compartment 1 and matches with the corresponding notch 221 respectively; the flap 4 is provided with guide members 41 on both sides away from the hinged end, and the guide members 41 match with the corresponding slide rail 24. Preferably, the guide member 41 is a cantilever provided on one side of the flap 4, and the end of the cantilever is pivotally connected with a roller rolling along the slide groove of the slide rail 24; the two ends of the slide groove are also provided with transition zones 241 for conveniently changing the rolling path of the roller. The provision of the transition zone 241 can be more conducive to better engagement between the flap 4 and the notch 221 after unfolding, and also helps the top cover assembly 2 to leave a certain lifting space when engaging with the upper end of the flap 4, thereby better realizing the engagement and unlocking between the top cover assembly 2 and the flap 4. The working principle of the top cover assembly 2 and the flap 4 when engaging will be further described later.

[0042] With the car roof raising device adopting the above-mentioned structural design, when the top cover assembly 2 is acted upon by the lifting assembly 3 to move upward, the two flaps 4 are unfolded along the slide rail 24 through the guide member 41 and cooperate with the corresponding notches 221; conversely, when the top cover assembly 2 is acted upon by the lifting assembly 3 to move downward, the two flaps 4 are retracted along the slide rail 24 through the guide member 41 and separated from the corresponding notches 221, so that the top cover assembly 2 cooperates with the flaps 4 to form a sealed space when it is unfolded, and will not form an obstruction on the opposite side walls of the car body 1 when it is retracted, thereby bringing greater convenience to the raising and lowering of the car roof.

[0043] Furthermore, the top cover assembly 2 further comprises an unlocking assembly 25 and an elastic tensioning assembly 26 for assisting the retraction of the flap 4; the unlocking assembly 25 comprises an elastic positioning pin 251 disposed in the notch 221, and an elastic latch 252 cooperating with the elastic positioning pin 251; the elastic positioning pin 251 cooperates with the positioning groove 42 provided at the top of the flap 4, and the elastic latch 252 cooperates with the positioning hole 2512 radially disposed on the elastic positioning pin 251; preferably, in order to facilitate the cooperation with the unfolded flap 4, the elastic positioning pin 251 is provided Placed at one end of the long side of the notch 221, the elastic pin 252 is arranged on the side wall of the notch 221 and adjacent to the elastic positioning pin 251, so that the unfolded flap 4 is locked and positioned through the cooperation of the elastic positioning pin 251 and the elastic pin 252; in addition, in order to facilitate the folding of the flap 4, the above-mentioned elastic tensioning member includes a spring 261, and a hook 262 arranged at one end of the spring 261 facing the flap 4, and the hook cooperates with the flap 4, so that when the elastic positioning pin 251 is separated from the flap 4, the flap 4 is folded under the pulling force of the spring 261.

[0044] Furthermore, the working principle of the above-mentioned flap 4 when unfolded is described as follows:

[0045] When the flap 4 is unfolded, the top cover assembly 2 is gradually lifted up by the lifting assembly 3, and the roller rolls toward the end of the slide groove provided with the transition zone 241, and the roller at one end of the elastic latch 252 is squeezed by the flap 4, so that the other end of the elastic latch 252 is separated from the elastic positioning pin 251, and the elastic positioning pin 251 pops out downward;

[0046] When the top cover assembly 2 is raised to the highest position by the lifting assembly 3, the roller rolls into the transition zone 241; the elastic pin 252 is provided with one end of the roller separated from the flap 4, and the exposed end of the elastic positioning pin 251 is squeezed by the flap 4 and cooperates with the positioning groove 42 at the top of the flap 4; the end of the elastic pin 252 that cooperates with the elastic positioning pin 251 is inserted into the positioning hole 2512 on the side wall of the elastic positioning pin 251 under the action of its own elastic force; at this time, the above-mentioned hook is pulled by the flap 4 so that the spring 261 is in a tensioned state; because the elastic positioning pin 251 inserted at the top of the flap 4 has been locked by the elastic pin 252 at this time, that is, the elastic pin 252 is inserted into the positioning hole 2512 on the side wall of the elastic positioning pin 251, the flap 4 will not be flipped inward by the pulling force of the spring 261.

[0047] Furthermore, when the top cover assembly 2 is raised to the highest position, there will be a certain gap between the flap 4 and the flap 4. In order to make the top of the flap 4 fit more tightly with the notch 221, when the top cover assembly 2 is lowered by the lifting assembly 3, the end of the flap 4 away from the hinge axis, that is, the upper end of the flap, fits with the notch 221, and the flap 4 is unfolded and locked.

[0048] It should be noted that the positioning groove 42 arranged at the top of the flap 4 is opened on the inner side wall and the top surface of the flap 4. In order to prevent the flap 4 from getting stuck when being squeezed with the lower end of the elastic latch 252, the lower end of the elastic latch 252 is also pivotally connected to a roller, and the lower end of the elastic positioning pin 251 is also provided with a slope 2511, so that when the flap 4 is unfolded, the roller at the lower end of the elastic latch 252 is first squeezed to separate the elastic latch 252 from the elastic positioning pin 251. In addition, the flap 4 simultaneously squeezes the slope, thereby lifting the elastic positioning pin 251 upward, and then falls into the positioning groove 42 due to its own elastic force.

[0049] Furthermore, the working principle of the flap 4 when it is folded is described as follows:

[0050] When it is necessary to fold the flap 4, after the flap 4 is unfolded, due to the relatively wide transition zone 241, the lifting assembly 3 drives the top cover assembly 2 to slightly lift upward, and then drives the elastic positioning pin 251 and the elastic plug pin 252 to lift upward synchronously, and finally separates the elastic positioning pin 251 from the positioning groove 42 on the flap 4. At this time, under the pulling force of the spring 261, the flap 4 tilts inward, and then the lifting assembly 3 drives the top cover assembly 2 to move downward, so that the flap 4 is folded inward along the slide rail through the guide member 41 set on the side wall until the two flaps 4 facing each other are completely folded.

[0051] The folding and unfolding of the above-mentioned flap 4 does not require manual operation. The automatic folding and unfolding of the flap 4 can be achieved only by controlling the top cover assembly 2 through the lifting assembly 3. When the two relatively arranged flaps 4 are fully unfolded and cooperate with the top cover assembly 2, they can be enclosed to form a relatively closed independent space; on the contrary, when the flap 4 is separated from the top cover assembly 2 and folded, it will not block the opposite side walls of the compartment 1.

[0052] Furthermore, in order to limit the unfolded flap 4, a limiting flange 2211 is provided at the edge of the notch 221 close to the outer side of the long side wall. In order to increase the sealing performance, a sealing ring, a sealing airbag or other sealing components may be preset on the inner side of the limiting flange 2211 to increase the sealing performance after the flap 4 and the notch 221 are matched.

[0053] In addition, in order to further improve the stability of the flap 4 when it cooperates with the notch 221 after it is unfolded, a card slot 2212 is provided on the side of the notch 221 close to the top cover 21. When the flap 4 is unfolded, the card slot 2212 is sealed and engaged with the top of the flap 4; when the flap 4 is folded, the card slot 2212 is sealed and engaged with the top of the side panel at the open end, thereby increasing the sealing between the notch 221 and the lower compartment 1; in addition, in order to increase the sealing between the hinged end of the flap 4 and the compartment 1 after it is unfolded, a waterproof groove 43 is also provided at the hinged end of the flap 4. When the flap 4 is unfolded, the waterproof groove 43 is engaged with a positioning protrusion arranged at the top of the side panel of the compartment 1.

[0054] The present embodiment also provides a motorhome, which adopts the above-mentioned car roof lifting device, which can not only effectively expand the use space and area of ​​the car, but also bring greater convenience to the use of the motorhome through the retraction and extension of the flap 4 in the car roof lifting device.

[0055] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the scope of protection of the present invention.
