[0029] Reference Figures 1 to 8 The vehicle-mounted detachable automatic exhibition stand of an embodiment of the invention includes a exhibition stand body 1 and a lifting device 2 arranged outside the exhibition stand body 1. The lifting device 2 includes an extension mechanism 21 and retractable legs 22 fixed on both sides of the extension mechanism 21.

[0030] Specifically, the booth body 1 includes a fixed floor 11, a top storage plate 12 arranged above the fixed floor 11, and extended side plates 13 respectively installed on both sides of the top storage plate 12. A lifting mechanism 14 is provided between the fixed floor 11 and the top storage plate 12; folding floors 15 are symmetrically arranged in the middle of both sides of the fixed floor 11, and the extended side plates 13 include an upper side plate 131, a middle side plate 132 and a lower side plate 133. The bottom edges of the lower side plates 133 are respectively hinged to the outer edges of the folding floors 15 on the corresponding sides, and the top edge of the upper side plate 131 is connected to the side edge of the top storage plate 12 by a hinge. One end of the middle side plate 132 is hinged to the inner lower end of the upper side plate 131 and the other end is hinged to the top end of the lower side plate 133. A number of two-way transverse expansion mechanisms 16 are provided below the fixed floor 11, and the two ends of each two-way transverse expansion mechanism 16 are respectively connected to the lower side plates 133 on both sides.

[0031] This vehicle-mounted detachable automatic construction booth has a lifting device 2 on the outside of the booth body 1, which enables it to be separated from the truck frame and fall to the ground independently after transportation without the use of external lifting equipment, and is flexible to move; a lifting mechanism 14 is set between the fixed floor 11 and the top warehouse plate 12 of the booth body 1, and a number of two-way horizontal expansion mechanisms 16 connecting the two lower side panels 133 are set under the fixed floor 11. The lifting mechanism 14 can drive the top warehouse plate 12 to move upward, thereby driving the expansion of each expanded side panel 13, and then under the drive of the two-way horizontal expansion mechanism 16, the lower side panel 133 slides outward to drive the folded floor 15 to open to a flat state, and pushes the lower end of the middle side panel 132 outward, finally forming a double-layer booth with both sides expanded, which increases space utilization. The whole process does not require manual operation, which greatly shortens the construction time.

[0032] In this embodiment, a partition layer 17 is connected between the top ends of the two lower side panels 133. This partition layer 17 comprises a central panel 171 and folding panels 172 positioned on either side of the central panel 171. Each folding panel 172 is hingedly connected to the central panel 171 and the lower side panels 133. The folding panels 172 and the folding floor 15 each comprise a pair of hinged hinged panels. Furthermore, a plurality of load cylinders 173 are positioned on either side below the central panel 171. Each load cylinder 173 has a fixed end connected to the central panel 171 and a movable end connected to the corresponding folding panel 172, thereby forming a supporting lever. Specifically, the bottom of the folding panels 172 is provided with a keyway, through which the extension rod of the load cylinder 173 passes to connect to the folding panel 172. When the vehicle-mounted, detachable, and automatically erected exhibition stand is retracted, the folding panels 172 and folding floor 15 are both folded in half. When the vehicle-mounted, detachable, and automatically erected exhibition stand is deployed, the folding panels 172, driven by the lower side panels 133, extend laterally, fully unfolding the partition 17, thus strictly dividing the interior space of the exhibition stand into an upper and lower level. When the folding panels 172 are deployed, the load cylinder 173 extends within the keyway. Once the keyway reaches its maximum displacement, the folding panels 172 begin to receive the force of the load cylinder 173. This force flattens the surface connecting the folding panels 172 and the central panel 171. Supported by the partition 17, the overall spatial structure of the deployed vehicle-mounted, detachable, and automatically erected exhibition stand becomes more stable and reliable.

[0033] Furthermore, to facilitate access to the upper booths, a staircase is installed beneath the central shelf 171, connecting the lower and upper booths. Furthermore, if space separation is required, a central partition wall 18 can be installed beneath the central shelf 171. This partition wall 18 can be embedded with a television or LED screen for advertising.

[0034] Specifically, in this embodiment, an outer storage plate 111 and an inner storage plate 112 are spaced apart at the front and rear ends of the fixed floor 11, and a middle storage plate 121 is fixed at the front and rear ends of the top storage plate 12 respectively. When the vehicle-mounted detachable automatic construction booth is in a compressed state, the middle storage plate 121 can be embedded in the gap between the outer storage plate 111 and the inner storage plate 112.

[0035] like Figure 4 As shown, the lifting device 2 of this embodiment includes two extension mechanisms 21, each connected to the two outer storage plates 111. A retractable leg 22 is fixed to each side of each extension mechanism 21. The retractable leg 22 comprises an outer leg tube connected to the extension mechanism 21 and an embedded leg inserted into the outer leg tube. A leg drive device is fixed to the side of the outer leg tube, and the movable end of the leg drive device is connected to the embedded leg. The leg drive device in this embodiment is a cylinder. Driven by the cylinder, the embedded leg can be extended and lowered along the outer leg tube. More specifically, the extension mechanism 21 includes a fixed tube fixed to the inner wall of the outer storage plate 111 and movable arms embedded from both ends of the fixed tube. To achieve automatic extension and retraction of the extension mechanism 21, a double-rod cylinder is installed in the fixed tube as a power mechanism. The two movable rods of the double-rod cylinder are respectively connected to the movable arms at the corresponding ends. The provision of the lifting device 2 enables the vehicle-mounted detachable automatic construction booth to be moved without the need for external equipment such as a crane to lift it onto a truck, thereby reducing transportation costs and greatly shortening transportation time.

[0036] More specifically, in this embodiment, to improve the sealing performance of the vehicle-mounted, detachable, and automatically erected exhibition stand after deployment and to prevent items within the stand from being affected by strong winds or rain during inclement weather, such as windy or rainy days, an upper revolving door 19a and a lower revolving door 19b are hingedly connected to both sides of each inner compartment panel 112 and lower side panel 133. Each upper revolving door 19a can be rotated to engage with the side edge of the middle side panel 132, and each lower revolving door 19b can be rotated to engage with the side edge of the inner compartment panel 112. Furthermore, each upper revolving door 19a and each lower revolving door 19b are driven to rotate by a rotation mechanism, thereby achieving an automatic rotation function.

[0037] In this embodiment, the lifting mechanism 14 includes outer lifting tubes 141 disposed at each corner of the fixed floor 11, inner lifting tubes 142 nested within each outer lifting tube 141, and hydraulic cylinders 143 for driving the lifting of each inner lifting tube 142. The bottom end of each outer lifting tube 141 and the top end of each inner lifting tube 142 are connected to the fixed floor 11 and the top of the top deck 12, respectively. The cylinder body of each hydraulic cylinder 143 is fixed to the outer wall of the outer lifting tube 141, and the extension rod is connected to the inner lifting tube 142. Driven by the hydraulic cylinder 143, the inner lifting tube 142 can be moved up and down along the outer lifting tube 141, thereby driving the lifting and lowering movement of the top deck 12, completing the expansion or contraction of the folding compartment.

[0038] Specifically, the bidirectional horizontal expansion mechanism 16 of this embodiment includes at least one pair of extension rods connected to expansion cylinders 161 on the two lower side plates 133. The lower side plates 133 are provided with cylinder seats for the ends of the extension rods of each expansion cylinder 161 to be placed. The cylinder seats and the ends of the mating extension rods are welded to ensure a secure connection. Furthermore, telescopic guide rails are provided on the fixed floor 11 next to the expansion cylinders 161. These telescopic guide rails are divided into a first guide rail 1621 and a second guide rail 1622 embedded in the first guide rail 1621. The first guide rail 1621 is fixed to the cylinder body of the expansion cylinder 161, and the end of the second guide rail 1622 is connected to the end of the extension rod of the expansion cylinder 161 via bolts or other fasteners.

[0039] Preferably, at least one pair of guide rail assemblies is connected between the fixed floor 11 and the two lower side panels 133. The guide rail assembly comprises an outer guide rail 1631 and an inner guide rail 1632, one end of which is embedded within the outer guide rail 1631. The outer guide rail 1631 is fixed to the bottom of the fixed floor 11, and the other end of the inner guide rail 1632 is connected to the lower side panels 133. A reinforcement member 1633 is provided between the inner and outer guide rails 1632, 1631, with the two ends of the reinforcement member 1633 respectively embedded in the outer and inner guide rails 1631 and 1632. The guide rail assembly of this embodiment cooperates with the bidirectional transverse expansion mechanism 16 to ensure that the path of the lower side panels 133 does not deviate during the transverse sliding process, ensuring smooth expansion of the exhibition stand. At the same time, the guide rail assembly adopts an embedded three-section structure, which increases structural strength, effectively improves service life, and is more reliable and safe.

[0040] The vehicle-mounted, detachable, and automatically erected exhibition stand of the embodiment of the present invention can be transported and moved by truck, automatically detached and unloaded from the truck, and lowered to the ground for use. It can also automatically expand horizontally and vertically in multiple levels to form a double-layer display platform, increasing the interior space by 3-5 times. Its exterior color, interior decoration, equipment and facilities, lighting, communication network, etc. can be customized according to customer needs. It transforms from a square box into a double-layer, multifunctional display platform, meeting both the external dimension restrictions of the box under transportation regulations and the need for extra-large space when the stand is in use. After the event, the stand can automatically retract and descend, and then be transported and moved by truck, enabling it to be reused in multiple locations, greatly reducing the workload of repeated booth construction and reducing the operating costs of the user unit.

[0041] Of course, the design and creation of the present invention are not limited to the above-mentioned embodiments. Those skilled in the art can also make equivalent modifications or substitutions without violating the spirit of the present invention.
