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

[0039] In combination Figures 1 to 10 As shown in the drawings, the present embodiment provides a carriage roof lifting device, which comprises a compartment body 1, a roof cover assembly 2 slidably connected with the side wall of the compartment body 1, a lifting assembly 3 for driving the roof cover assembly 2 to move along the height direction of the compartment body 1, and a flap 4 matched with the notch 221 in the roof cover assembly 2. With the structure of the carriage roof lifting device, the automatic folding and unfolding of the flap 4 can be realized, and at the same time, the cooperation and separation of the flap 4 and the notch 221 can form a sealed space when the roof cover assembly 2 is unfolded, and will not block the relative two side walls of the compartment body 1 after being folded. As a preferred embodiment, the lifting assembly 3 is provided as a lifting cylinder or an electric push rod, and the mounting position of the lifting assembly 3 is provided with a sealing element for the sealing connection of the roof cover assembly 2 and the compartment body 1. The specific arrangement of the sealing element is commonly used in the related art, and will not be described in detail here.

[0040] Specifically, the top of the compartment body 1 is provided with an opening, and the roof cover assembly 2 is covered on the upper end of the opening and slidably connected with the side wall of the compartment body 1. Preferably, the roof cover assembly 2 comprises a roof cover 21, and long side walls and short side walls 23 arranged around the roof cover 21 and opposite to each other. In addition, in order to cooperate with the folding and unfolding 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 matched with the corresponding flaps 4.

[0041] Further, the flap 4 is hinged to the opening end of the compartment body 1 and matched with the corresponding notch 221. The opposite sides of the flap 4 away from the hinged end are both provided with guide elements 41 matched with the corresponding slide rails 24. Preferably, the guide element 41 is a cantilever provided on one side of the flap 4, and the end of the cantilever is pivoted with a roller rolling along the sliding groove of the slide rail 24. The two ends of the sliding groove are also respectively provided with transition zones 241 for facilitating the change of the rolling path of the roller. The arrangement of the transition zones 241 can better facilitate the engagement of the unfolded flap 4 with the notch 221, and also facilitate the lifting space of the roof cover assembly 2 when the upper end of the flap 4 is engaged, thereby better realizing the engagement and unlocking between the roof cover assembly 2 and the flap 4. The working principle of the cooperation between the roof cover assembly 2 and the flap 4 will be further described later.

[0042] The carriage roof lifting device with the above structure is designed, when the roof cover assembly 2 is lifted upward by the lifting assembly 3, the two flaps 4 are unfolded along the slide rail 24 by the guide 41 and matched with the corresponding notch 221; on the contrary, when the roof cover assembly 2 is lowered by the lifting assembly 3, the two flaps 4 are folded along the slide rail 24 by the guide 41 and separated from the corresponding notch 221, so that the roof cover assembly 2 is matched with the flaps 4 to form a sealed space when unfolded, and the carriage body 1 is not blocked by the two side walls when folded, thereby bringing great convenience to the lifting and lowering of the carriage roof.

[0043] Furthermore, the roof cover assembly 2 further comprises an unlocking assembly 25 and an elastic tensioning assembly 26 for assisting the folding of the flap 4; the unlocking assembly 25 comprises an elastic positioning pin 251 arranged in the notch 221 and an elastic latch 252 matched with the elastic positioning pin 251; the elastic positioning pin 251 is matched with the positioning groove 42 arranged on the top of the flap 4, and the elastic latch 252 is matched with the positioning hole 2512 arranged radially on the elastic positioning pin 251; as an optimization, in order to facilitate the matching with the unfolded flap 4, the elastic positioning pin 251 is arranged at one end of the long side of the notch 221, and the elastic latch 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 by the cooperation of the elastic positioning pin 251 and the elastic latch 252; in addition, in order to facilitate the folding of the flap 4, the elastic tensioning assembly comprises a spring 261 and a catch 262 arranged at one end of the spring 261 towards the flap 4, and the catch is matched 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 unfolding of the flap 4 is described as follows:

[0045] When the flap 4 is unfolded, the roof cover assembly 2 is gradually lifted by the lifting assembly 3, the roller is rolled to one end of the transition zone 241 of the slide groove, the roller at one end of the elastic latch 252 is pressed 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 is popped out downward;

[0046] When the top cover assembly 2 is lifted to the highest position by the lifting assembly 3, the roller rolls into the transition area 241; the end of the elastic latch 252 provided with the roller is separated from the flap 4, the exposed end of the elastic positioning pin 251 is pressed by the flap 4 and cooperates with the positioning groove 42 at the top end of the flap 4; the end of the elastic latch 252 cooperating 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 clamping hook is pulled by the flap 4, so that the spring 261 is in a tension state; because the elastic positioning pin 251 inserted at the top end of the flap 4 is locked by the elastic latch 252 at this time, that is, the elastic latch 252 is inserted into the positioning hole 2512 on the side wall of the elastic positioning pin 251, therefore the flap 4 will not be turned inward by the tension of the spring 261.

[0047] Further, because there is a gap between the top cover assembly 2 and the flap 4 when the top cover assembly 2 is lifted to the highest position, in order to make the top of the flap 4 cooperate with the gap 221 more tightly, when the top cover assembly 2 is lowered by the lifting assembly 3, the end of the flap 4 away from the hinge shaft, that is, the upper end of the flap cooperates with the gap 221, the flap 4 is unfolded and locked.

[0048] It should be noted that the positioning groove 42 provided at the top end of the flap 4 is opened in the inner side wall and top surface of the flap 4, in order to facilitate the flap 4 not to be stuck when being pressed by the lower end of the elastic latch 252, the lower end of the elastic latch 252 is further pivoted with a roller, and the lower end of the elastic positioning pin 251 is further 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 pressed first, so that the elastic latch 252 is separated from the elastic positioning pin 251, in addition, the flap 4 simultaneously presses the slope, so that the elastic positioning pin 251 is lifted upward, and then falls into the positioning groove 42 under the action of its own elastic force.

[0049] Further, the working principle of the above-mentioned flap 4 when it is folded is as follows:

[0050] When it is needed to fold the flap 4, after the above-mentioned unfolded state of the flap 4, because the transition area 241 is relatively wide, under the action of the lifting assembly 3, the top cover assembly 2 is first slightly lifted upward, then the elastic positioning pin 251 and the elastic latch 252 are simultaneously lifted upward, finally the elastic positioning pin 251 is separated from the positioning groove 42 on the flap 4, at this time, under the action of the tension of the spring 261, the flap 4 is inclined inward, then the top cover assembly 2 is driven downward by the lifting assembly 3, so that the flap 4 is folded inward along the slide rail by the guide 41 provided on the side wall, until the two flaps 4 are completely folded.

[0051] The folding plate 4 can be automatically folded and unfolded without manual operation, and only by controlling the top cover assembly 2 by the lifting assembly 3, the folding plate 4 can be automatically folded and unfolded, and when the two folding plates 4 arranged oppositely are completely unfolded, the folding plate 4 cooperates with the top cover assembly 2 to form a relatively closed independent space; on the contrary, when the folding plate 4 is separated from the top cover assembly 2 and is folded, the folding plate 4 does not form an obstacle to the two side walls of the compartment 1.

[0052] Further, in order to limit the unfolded folding plate 4, a limiting flange 2211 is arranged at the edge of the gap 221 close to the outer side of the long side wall, and in order to increase the sealing performance, a sealing member such as a sealing ring or a sealing air bag is arranged on the inner side of the limiting flange 2211, so as to increase the sealing performance of the gap 221 and the folding plate 4.

[0053] In addition, in order to further improve the stability of the gap 221 and the folding plate 4 when the folding plate 4 is unfolded, a clamping groove 2212 is arranged on one side of the gap 221 close to the top cover 21, and when the folding plate 4 is unfolded, the clamping groove 2212 is sealingly clamped with the top of the folding plate 4; when the folding plate 4 is folded, the clamping groove 2212 is sealingly clamped with the top of the opening end side plate, so as to increase the sealing performance between the gap 221 and the compartment 1 below; in addition, in order to increase the sealing performance between the hinge end of the folding plate 4 and the compartment 1 when the folding plate 4 is unfolded, the hinge end of the folding plate 4 is also provided with a waterproof groove 43, and when the folding plate 4 is unfolded, the waterproof groove 43 is clamped with the positioning protrusion arranged on the top of the side plate of the compartment 1.

[0054] The embodiment also provides a motor home adopting the compartment lifting top device, which can effectively expand the use space and area of the compartment, and can bring great convenience to the use of the motor home through the folding and unfolding of the folding plate 4 in the compartment lifting top device.

[0055] The technical principles of the utility model are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the utility model, and cannot be interpreted as limiting the protection scope of the utility model in any way. Based on the explanations herein, other specific embodiments of the utility model can be conceived by those skilled in the art without creative labor, and these embodiments will fall within the protection scope of the utility model.
