Examples of the embodiments are shown in the accompanying drawings, where like or similar reference numerals denote like or similar elements or elements having the same or similar functions throughout. Additionally, spatial relationship terms such as "above", "upper", "below", "lower" are used for convenience of description to explain the positional relationship between two components. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0029] Please refer to Figures 1 to 4 , this application provides a roof tent, including: a bottom shell 110, a top shell 120, a hydraulic lifting device 130, two bed boards (bed board 140 and bed board 150), and a tent body 160.

[0030] Among them, the lower surface of the bottom shell 110 can be fixedly connected to the roof 100. Specifically, as Figure 4 and Figure 8 shown, the roof tent further includes: a connecting rod 170 and a connecting piece 180; the roof 100 is fixedly connected to a roof crossbar 101; the lower surface of the bottom shell 110 is fixedly connected to the connecting rod 170, and the connecting rod 170 is placed intersecting with the roof crossbar 101 above the roof crossbar 101; the connecting piece 180 is placed intersecting with the roof crossbar 101 below the roof crossbar 101, and the connecting piece 180 is detachably connected to the connecting rod 170, for example: bolt connection. Preferably, the connecting rod 170 has a groove, and the opening width of the groove is smaller than the internal width of the groove; the nut of the bolt is embedded in the groove of the connecting rod 170, the screw of the bolt passes through the through hole of the connecting piece 180 from the opening of the groove, and the nut cooperates with the bolt below the connecting piece 180, so as to fix the connecting piece 180 and the connecting rod 170 to the roof crossbar 101 through the bolt, and further realize the fixed connection between the bottom shell 110 and the roof 100.

[0031] Specifically, both ends of the connecting rod 170 and the connecting piece 180 are fixed by bolts. Of course, one end of the connecting rod 170 and the connecting piece 180 can also be hinged, and the other end is fixedly connected by bolts. More preferably, on the roof 100, there are two parallel roof crossbars 101. Correspondingly, the lower surface of the bottom shell 110 also has two groups of parallel connecting rods 170 and connecting pieces 180, and each group of connecting rods 170 and connecting pieces 180 cooperates with a roof crossbar 101 to achieve fixed connection.

[0032] In addition, as Figures 2 to 4As shown, two opposite sides of the bottom shell 110 are respectively hinged to one side of two bed boards (bed board 140 and bed board 150). That is, one side of the bottom shell 110 is hinged to one side of the bed board 140, and the other opposite side of the bottom shell 110 is hinged to one side of the bed board 150. In this way, when the two bed boards (bed board 140 and bed board 150) are opened, the two bed boards (bed board 140 and bed board 150) are located on both sides of the bottom shell 110. When the two bed boards (bed board 140 and bed board 150) are closed, the two bed boards (bed board 140 and bed board 150) are located above the bottom shell 110. Preferably, the two sides of the bottom shell 110 facing the head and tail directions of the vehicle are respectively hinged to the bed board 140 and the bed board 150. The positions of the upper surface of the bottom shell 110 near the other two opposite sides are respectively fixedly connected to the lower ends of the hydraulic lifting devices 130 with the telescopic direction being the vertical direction. Preferably, the two opposite sides of the bottom shell 110 facing the two sides of the vehicle are respectively fixedly connected to the lower ends of the hydraulic lifting devices 130.

[0033] Specifically, as Figure 3 and Figure 6 shown, the roof tent further includes: a hinge 190. Through the hinge 190, the hinging of the bed boards (bed board 140 and bed board 150) to the bottom shell 110 and the fixed connection of the lower ends of the hydraulic lifting devices 130 to the bottom shell 110 are realized. The hinge 190 has a fixed part 191 and a hinged part 192; the fixed part 191 is provided with a mounting groove with an opening facing upward, and the bottom of the mounting groove is fixed to the bottom shell 110. For example, the bottom of the mounting groove is riveted to the bottom shell 110 through a rivet, and the lower end of the hydraulic lifting device 130 is fixed in the mounting groove, so as to realize the fixed connection of the lower end of the hydraulic lifting device 130 to the bottom shell 110; the hinged part 192 is hinged to both ends of the fixed part 191, and the hinged part 192 is fixedly connected to the bed boards (bed board 140 and bed board 150), so as to realize the hinging of the bed boards to the bottom shell 110. For example, hinge holes are provided at both ends of the fixed part 191, and a hinge hole is also provided at one end of the hinged part 192. A hinge shaft passes through the hinge holes of the fixed part 191 and the hinged part 192, so as to hinge the hinged part 192 to the fixed part 191, and the end of the hinged part 192 away from the fixed part 191 is fixedly connected to the bed boards (bed board 140 and bed board 150), so as to realize the fixation of the bed boards to the hinged part 192. In order to prevent the fixed part 191 of the hinge 190 from blocking the closing of the bed boards when the two bed boards are closed, preferably, the end of the hinged part 192 away from the fixed part 191 is bent inward, that is, bent toward the inside of the roof tent, so that the position where the hinged part 192 is fixed to the bed boards can be offset from the position of the fixed part 191 in the vertical direction.

[0034] The upper end of the hydraulic lifting device 130 is fixedly connected to the lower surface of the top shell 120, and specifically, it can be fixedly connected by means of bolts and rivets. In order to ensure that the space when the roof tent is opened can be increased outward from each side of the bottom shell 110 and the top shell 120, preferably, a hydraulic lifting device 130 is provided at each corner position of the upper surface of the bottom shell 110, so as to avoid the hydraulic lifting device 130 arranged from hindering the space when the roof tent is opened and increased outward from each side of the bottom shell 110 and the top shell 120.

[0035] Specifically, as Figure 7 shown, the hydraulic lifting device 130 includes: a support bottom plate 131 fixed in the installation groove of the fixing part 191, a support top plate 132 fixed to the lower surface of the top shell 120, a hydraulic cylinder 133, four first hinge plates 134 and an even number of second hinge plates 135.

[0036] Among them, the first end of the first hinge plate 134 is hinged to the middle of the support bottom plate 131, and the second end of the second first hinge plate 134 is hinged to the middle of the support top plate 132. There is one or more second hinge plates 135 between the first first hinge plate 134 and the second first hinge plate 134. Half of the above-mentioned second hinge plates 135 are sequentially hinged end to end and bent. Moreover, the first end of the first second hinge plate 135 is hinged and bent with the second end of the first first hinge plate 134, and the second end of the last second hinge plate 135 is hinged and bent with the first end of the second first hinge plate 134, so that the two first hinge plates 134 and half of the above-mentioned second hinge plates 135 form a first set of telescopic mechanisms; the first end of the third first hinge plate 134 is hinged to the middle of the support bottom plate 131, and the second end of the fourth first hinge plate 134 is hinged to the middle of the support top plate 132. There is one or more second hinge plates 135 between the third first hinge plate 134 and the fourth first hinge plate 134. The remaining half of the above-mentioned second hinge plates 135 are sequentially hinged end to end and bent. Moreover, the first end of the first second hinge plate 135 is hinged and bent with the second end of the third first hinge plate 134, and the second end of the last second hinge plate 135 is hinged and bent with the first end of the fourth first hinge plate 134, so that the two first hinge plates 134 and the remaining half of the above-mentioned second hinge plates 135 form a second set of telescopic mechanisms; each second hinge plate 135 of the first set of telescopic mechanisms crosses the corresponding second hinge plate 135 of the second set of telescopic mechanisms and is hinged at the crossing point (preferably the middle part of the crossing point). That is, the first second hinge plate 135 of the first set of telescopic mechanisms is hinged to the first second hinge plate 135 of the second set of telescopic mechanisms at the middle part, the second second hinge plate 135 of the first set of telescopic mechanisms is hinged to the second second hinge plate 135 of the second set of telescopic mechanisms at the middle part, and so on. The last second hinge plate 135 of the first set of telescopic mechanisms is hinged to the last second hinge plate 135 of the second set of telescopic mechanisms at the middle part, so that the first set of telescopic mechanisms and the second set of telescopic mechanisms are tightly connected, thereby increasing the overall stability.

[0037] On the above basis, one end of the hydraulic cylinder 133 is hinged to one side of the support bottom plate 131, and the other end is hinged to the end where the first first hinge plate 134 or the third first hinge plate 134 is hinged to the second hinge plate 135. Specifically, a connecting rod 136 extending outward can be fixed to the surface of the first first hinge plate 134 or the third first hinge plate 134 facing the hydraulic cylinder 133, and the hydraulic cylinder 133 is hinged to the connecting rod 136. The rotation of the first hinge plate 134 and the second hinge plate 135 is controlled by the telescopic movement of the hydraulic cylinder 133, so as to control the distance between the first hinge plate 134 and the second hinge plate 135, and between the two second hinge plates 135, and further vertically control the telescopic movement.

[0038] In addition, if Figure 4 and Figure 9 As shown, a bedside baffle 210 is fixed to one side of the hinged bed board (bed board 140 and bed board 150) on the bottom shell 110, and the bed board baffle 210 is located below the bed board (bed board 140 or bed board 150) to support the bed board (bed board 140 and bed board 150). Preferably, the bedside baffle 210 includes: a connecting angle steel 211 and a supporting wing 212, the connecting angle steel 211 is buckled and fixed to the side of the hinged bed board of the bottom shell 110, and the supporting wing 212 extends outward from the side of the connecting angle steel 211, that is, extends in a direction away from the angle steel 211. After the bottom plate (bottom plate 140 and bottom plate 150) is opened, the bottom plate (bottom plate 140 and bottom plate 150) is placed on the supporting wing 212 to support the bed board. Preferably, the distance from the upper surface of the supporting wing 212 to the upper surface of the connecting angle steel 211 is the same as the thickness of the bed board, thereby ensuring that the upper surface of the bed board is flush with the upper surface of the bottom shell 110 after the bed board is opened.

[0039] In addition, if Figures 2 to 4 As shown, the tent body 160 is a soft tent, such as a canvas tent, and a lamp 250 can be arranged inside the tent body 160 to provide light inside the tent body 160. Among them, all edges of the bed board that are not hinged to the bottom shell 110 and all edges of the bottom shell 110 that are not hinged to the bed board are connected to the lower edge of the tent body 160, so that the lower edge of the tent body 160 is closed. The upper edge of the tent body 160 is connected to all edges of the top shell 120, so that the upper edge of the tent body 160 is closed. Each side or several sides of the tent body 160 have a tent air-increasing tent 161 with an opening facing the inside of the tent body 160 and an extension direction facing the outside of the tent body 160, and the tent air-increasing tent 161 is supported from bottom to top in the tent air-increasing tent 161 by a support rod 220, so that the tent air-increasing tent 161 is opened, thereby increasing the space inside the tent body 160.

[0040] Specifically, Figures 2 to 5 As shown, after the tent body 160 is opened, the upper surface of the tent canopy 161 is in the shape of a square or a rectangle; the two side surfaces connected to the upper surface are formed by connecting the horizontal straight edge, the vertical straight edge and the arc edge in sequence; the bottom surface is an arc surface; the arc bottom surface is connected to the outermost edge of the upper surface and the arc edge of the side surface, thereby forming a tent canopy 161 with an opening, and the opening of the tent canopy 161 is connected to the opening of the tent body 160, thereby forming a tent body 160 with a larger space. On this basis, the support pole 220 is also arc-shaped, and it opens the tent canopy 161 from top to bottom along the arc surface.

[0041] In addition, the opening of the tent air-increasing tent 161 toward the tent body 160 is a circular opening, that is, a circular opening is provided at the side of the tent body 160 leading to the tent air-increasing tent 161, and of course, a rectangular or square opening may also be provided. For example, a circular opening is provided at the side where the lower edge of the tent body 160 is connected to the bottom shell 110 and the bed board, while a rectangular or square opening is provided at the side where the lower edge of the tent body 160 is only connected to the bed board.

[0042] On the basis of the above, if Figures 2 to 4 As shown, the roof tent further includes: a ladder 230, wherein the lower surface of a bed board is hinged to the upper end of the ladder 230, and the lower end of the ladder 230 is supported on the ground, so that the user can climb from the ladder 230 to the roof tent. Figure 10 As shown, a ladder connector 240 is fixed to the lower surface of a bed board, and the ladder connector 240 has a fixing plate 241 and a hinged wing 242. The fixing plate 241 has a fixing hole through which screws or bolts are passed to fix to the bed board, and the hinged wing 242 has a hinge hole through which the bolts are hinged to the ladder. Preferably, the fixing plate 241 extends downward with two parallel hinged wings 242, each of which has a hinge hole, and the ladder 230 also has a hinged wing, and the hinged wing of the ladder 230 is inserted between the two hinged wings 242 extending downward from the fixing plate 241, thereby realizing the hinge connection between the ladder 230 and the bed board, making the hinge connection more reliable.

[0043] When the vehicle is driving, the roof tent is in a closed state, and the hydraulic telescopic device 130 is in a retracted state, that is, the hydraulic cylinder 133 is retracted, the first and second telescopic mechanisms are retracted, and the bed plate is rotated to the top of the bottom shell 110, and the tent is folded and retracted. When the vehicle stops, the roof tent can be opened, and the hydraulic telescopic device 130 is in an extended state, that is, the hydraulic cylinder 133 is extended, the first and second telescopic mechanisms are extended, and the bed plate is rotated to be flush with the bottom shell 110, and the tent is stretched and opened. It can be seen from the above that the roof tent provided by the present application uses both the lifting method and the folding method, which reduces the weight of the roof tent and reduces the area of ​​the roof occupied by the roof tent.

[0044] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
