In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as a general description based on the meaning of the terms and the present invention.

[0037] Reference Figure 1 , Figure 5 , this embodiment provides a folding mechanism, including,

[0038] The extension component 1 includes a first hinge component 11, a second hinge component 12 and a connecting component 13. The first hinge component 11 is hinged to the second hinge component 12, and two ends of the connecting component 13 are respectively connected to the first hinge component 11 and the second hinge component 12;

[0039] The driving component 2 includes a first power assembly 21, a second power assembly 22 and a guide assembly 23. The first power assembly 21 is used to unfold the first hinge assembly 11, the second power assembly 22 is used to unfold the second hinge assembly 12, and the guide assembly 23 is used to assist the second power assembly 22 in operating.

[0040] After the operation of the first power assembly 21 and the second power assembly 22, the first hinge assembly 11 and the second hinge assembly 12 can be driven to gradually expand until they are on the same horizontal plane. The design of the guide assembly 23 will improve the smoothness of the operation of the second power assembly 22.

[0041] As an embodiment provided in this application, Figure 5 , Figure 6 as well as Fig. 9 The first hinge assembly 11 includes an inner plate 111, first side frames 112 fixedly connected to both sides of the inner plate 111, and auxiliary wheels 113 installed inside the first side frames 112 on both sides;

[0042] The auxiliary wheels 113 are provided in two groups, and the two groups of auxiliary wheels 113 are respectively located at two ends inside the first side frame 112 , and the first side frames 112 on both sides of the inner plate 111 are hinged to the inner side of the mounting frame 324 .

[0043] The first power assembly 21 includes a first electric push cylinder 211 and an articulated frame 212 . The output end of the first electric push cylinder 211 is hinged to the articulated frame 212 . The articulated frame 212 is fixedly connected to the outside of the first side frame 112 of the inner plate 111 . The first electric push cylinder 211 is adapted to be installed on the outside of the top frame 312 .

[0044] When the first electric push cylinder 211 is started, the output end of the first electric push cylinder 211 will gradually extend. Due to the intersection of the first electric push cylinder 211 and the top frame 312 and the hinge connection between the output end of the first electric push cylinder 211 and the hinge frame 212, the first side frames 112 on both sides of the inner plate 111 are hinged with the inner side of the mounting frame 324, thereby driving the inner plate 111 to rotate through the first side frames 112 on both sides, so that the inner plate 111 is unfolded until the inner plate 111 remains horizontal. In addition, since the first electric push cylinder 211 is located on both sides of the top frame 312, the occupation of the effective space is reduced.

[0045] As an embodiment provided in this application, Figures 4 to 8 as well as Figure 10 to Figure 12 , the second hinge assembly 12 includes an outer plate 121, a second side frame 122 fixedly connected to both sides of the outer plate 121, and an extension plate 123 arranged at one end of the outer plate 121;

[0046] The second side frame 122 on the outer side of the outer plate 121 is hinged to the first side frame 112 on the outer side of the inner plate 111 , and the extension plate 123 is extended and retracted by an electric push cylinder arranged inside the second side frame 122 .

[0047] The second power assembly 22 includes a second electric push cylinder 221 , a rope 222 sleeved on the output end of the second electric push cylinder 221 , and a locking block 223 fixed on the outside of the rope 222 . The second electric push cylinder 221 is adapted to be installed on the outside of the fixing frame 323 .

[0048] The connecting assembly 13 includes an outer rod 131 and an inner rod 132 . The outer rod 131 is hinged to the inner rod 132 . The other end of the outer rod 131 is hinged to the first side frame 112 outside the inner plate 111 . The other end of the inner rod 132 is hinged to the second side frame 122 outside the outer plate 121 .

[0049] The guide assembly 23 includes a connection seat 231, a mounting shell 232 adapted to be mounted on one end of the connection seat 231, and a reinforcing rib 233 fixedly connected to the outside of the mounting shell 232. A guide wheel 234 is arranged inside the mounting shell 232. The connection seat 231 is adapted to be mounted on the inside of the mounting frame 324, and the rope 222 passes through the guide wheel 234 and two sets of auxiliary wheels 113 and is sleeved on the outside of the hinge shaft of the outer rod 131 and the inner rod 132.

[0050] When the first electric push cylinder 211 is started, the second electric push cylinder 221 is started at the same time. At this time, the second electric push cylinder 221 will gradually shrink, and then drive the rope 222 of the second electric push cylinder 221 to move. Since the rope 222 is sleeved on the outside of the hinge shaft of the outer rod 131 and the inner rod 132, the hinge shaft of the two will be pulled. At the same time, due to the unfolding of the inner plate 111, the outer plate 121 is also gradually unfolded until the inner plate 111 and the outer plate 121 are in a horizontal state. At the same time, in the process of the second electric push cylinder 221 pulling the rope 222, with the cooperation of the auxiliary wheel 113 and the guide wheel 234, the smooth movement of the rope 222 is guaranteed, and the stability of the unfolding of the outer plate 121 is ensured.

[0051] Since the auxiliary wheel 113 is located inside the first side frame 112 and the connecting seat 231 is installed in a hidden manner, the available space of the entire device can be guaranteed, and the hidden design of the second electric push cylinder 221 located at the bottom of the bottom plate 322 once again increases the available space inside the entire device.

[0052] In addition, by using multiple sets of different hidden designs to increase the overall available space of the device, two sets of fitted inner panels 111 and outer panels 121 can be simultaneously and quickly unfolded to ensure that the device can be quickly built. The device is small in size after being folded and stored, and is suitable for small spaces, further improving the practicality of the device.

[0053] Reference Figure 1 to Figure 3 This embodiment provides an expansion cabin, including a folding mechanism and an installation mechanism 3, the installation mechanism 3 includes a frame 31 and a supporting chassis 32, the frame 31 and the supporting chassis 32 are used to carry and install the extension component 1 and the driving component 2.

[0054] Through the design of the frame 31 and the supporting chassis 32, not only the overall installation of the equipment can be achieved, but also the rationality of the installation of the extension component 1 and the driving component 2 is ensured through a reasonably planned structure, effectively increasing the overall available space above the supporting chassis 32.

[0055] As an embodiment provided in this application, Figure 1 to Figure 3 The frame 31 includes four groups of vertical poles 311, a top frame 312 fixedly connected to the top ends of the four groups of vertical poles 311, a bottom frame 313 fixedly connected to the bottom ends of the four groups of vertical poles 311, and a support frame 314 fixedly connected between the top frame 312 and the bottom frame 313.

[0056] The supporting chassis 32 includes an I-shaped frame 321 fixedly connected to the inner side of the bottom frame 313 , a bottom plate 322 fixedly connected to the top of the I-shaped frame 321 , and a fixing frame 323 fixedly connected to the outer side of the I-shaped frame 321 . A mounting frame 324 is fixedly connected to the outer side of the I-shaped frame 321 .

[0057] The design of the I-shaped frame 321 being located at the bottom of the entire device can improve the overall firmness of the device, and can also cooperate with the mounting frame 324 on the outside to ensure the hidden installation of the device, thereby increasing the overall available space of the device.

[0058] Finally, it should be pointed out that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
