[0006] The other two sets of drive components are respectively connected to the side extension and retraction components, and the two sets of drive components independently control the extension and retraction of the side panels;

[0007] The side extension / retraction assembly includes a first link, a second link, a third link, a fourth link, a fifth link, and a sixth link. One end of the first link is connected to the top plate via a first hinge seat. One end of the second and third links are connected to the side plate via second and third hinge seats, respectively. The other ends of the first and second links are hinged to one end of the fourth link. The other ends of the third and fourth links are hinged to one end of the fifth link. The other end of the fifth link is connected to the drive assembly via a fourth hinge seat. Both ends of the sixth link are hinged to the fifth link and the drive unit of the drive assembly, respectively. The drive assembly provides horizontal traction force to the sixth link.

[0008] Furthermore, the sixth link consists of two parallel rods.

[0016] This invention utilizes side and rear deployment / retraction components to open the sides, rear, and top of the vehicle compartment, avoiding obstruction of antenna equipment. The side panels include intersecting side and top panels. Through the multi-link structure of the side deployment / retraction components, the top panel is folded while the side panels are deployed, reducing the lateral deployment volume. The drive assembly uses a motor and two drive shafts to simultaneously control linear drive modules on both sides, thereby synchronously controlling the two deployment / retraction components to achieve the deployment and retraction of the side and rear panels, improving the driving stability and reliability of the retracted and deployed states.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] like Figure 1 As shown, the carriage structure has a floor plate 91, a box 92 at the front end of the floor plate 91, side plates 93 on both sides of the floor plate 91, and the side plates 93 are hinged to the floor plate 91; a rear cabin plate 94 is provided at the rear of the floor plate 92, and the rear cabin plate 94 is hinged to the floor plate 91; two top plates 95 are provided, and the top plates 95 are respectively hinged to the side plates 93 on both sides; the floor plate 91, box 92, side plates 93, rear cabin plate 94 and top plate 95 form a cavity for installing antenna equipment.

[0027] This utility model provides a modular shelter deployment and recovery mechanism, such as... Figures 1-6 As shown, this is used to control the deployment of the side panels 93, rear hatch 94, and top panel 95 to deploy the antenna equipment on the left and right sides, rear, and top. This avoids obstructing the antenna equipment.

[0028] Specifically, the deployment and retraction mechanism includes a side deployment and retraction assembly 1, a rear deployment and retraction assembly 2, and three sets of drive assemblies 3 that drive the side deployment and retraction assembly 1 and the rear deployment and retraction assembly 2 respectively. The side deployment and retraction assembly 1 is located on both sides of the floor 91 of the carriage and is connected to the side panel 93 and the top panel 95 of the side compartment. The rear deployment and retraction assembly 2 is located at the rear of the floor 91 and is connected to the rear compartment 94.

[0029] A set of drive components 3 controls the horizontal position of the rear hatch when it rotates around the bottom plate 91 and unfolds.

[0030] The other two sets of drive components 3 are connected to the side extension and retraction components 1 respectively, and the two sets of drive components 3 independently control the extension and retraction of the side plate 93.

[0031] The side extension / retraction assembly 1 includes a first link 11, a second link 12, a third link 13, a fourth link 14, a fifth link 15, and a sixth link 16. One end of the first link 11 is connected to the top plate 95 via a first hinge seat 41. One end of the second link 12 and the third link 13 are connected to the side plate 93 via second hinge seats 42 and third hinge seats 43, respectively. The other ends of the first link 11 and the second link 12 are hinged to one end of the fourth link 14. The other ends of the third link 13 and the fourth link 14 are hinged to one end of the fifth link 15. The other end of the fifth link 15 is connected to the drive assembly 3 via a fourth hinge seat 44. Both ends of the sixth link 16 are hinged to the fifth link 15 and the drive part of the drive assembly 3, respectively. The drive assembly 3 provides horizontal traction force to the sixth link 16. The unfolding process is as follows: the drive assembly 3 controls one end of the sixth link 16 to move horizontally toward the side plate 93, thereby pushing the fifth link 15 to rotate around the fourth hinge seat 44. The fifth link 15 pushes the third link 13 to make the side plate 93 unfold outward. At the same time, through the cooperation of the fourth link 14 and the second link 12, the first link 11 pulls the top plate 95 to make the top plate 95 fold inward. The retraction process is as follows: the drive assembly 3 controls one end of the sixth link 16 to move horizontally toward one side of the side plate 93. The sixth link 16 pulls the fifth link 15 to rotate. The fifth link 15 pulls the third link 13 to control the side plate 93 to rotate around the bottom plate 91. At the same time, through the cooperation of the fourth link 14, the first link 11 and the second link 12, the top plate 95 is pulled and rotated around the upper end of the side plate 93, thereby reaching the retracted position.

[0032] In one embodiment, such as Figures 1-6 As shown, two sixth links 16 are arranged in parallel.

[0033] In one embodiment, such as Figures 1-6 As shown, the sixth link 16 and the fifth link 15 have an arc-shaped structure. By setting the arc-shaped structure, the height position of the hinge point between the fifth link 15 and the third link 13 and the fourth link 14 can be lowered when the link is deployed.

[0034] In one embodiment, such as Figures 1-6 As shown, the first connecting rod 11 includes a rod body 111 and a connector 112. One end of the rod body 111 is provided with a screw hole, and the connector 112 is threaded into the screw hole. The length of the first connecting rod 11 can then be adjusted to regulate the lifting height of the top plate when it is in the retracted position.

[0035] In one embodiment, such as Figures 1-6 As shown, the rear extension / retraction assembly 2 includes a seventh link 21, an eighth link 22, and a ninth link 23. One end of the seventh link 21 is connected to the rear cabin panel 94 via a fifth hinge seat 45, and the other end is hinged to one end of the eighth link 22. The other end of the eighth link 22 is connected to a set of drive assemblies 3 via a sixth hinge seat 46. Both ends of the ninth link 23 are hinged to the eighth link 22 and the drive part of the drive assembly 3, respectively. The drive assembly 3 provides horizontal traction force to the ninth link 23. The drive assembly 3 pulls the ninth link 23, causing the eighth link 22 to rotate around the sixth hinge seat 46, thereby controlling the extension and retraction of the rear cabin panel 94 via the seventh link 21.

[0036] In one embodiment, such as Figures 1-6 As shown, the drive assembly 3 includes a linear drive module 31, a drive shaft 32, a motor 33, and a commutator 34. The linear drive module 31 is mounted on the base plate 91. The motor 33 is connected to the linear drive module 31 via the drive shaft 32 and the commutator 34, and drives the linear drive module 31 to move. Specifically, the output end of the motor 33 is connected to the drive shaft 32, and the drive shaft 32 is connected to the linear drive module 31 via the commutator 34, thereby providing driving force to the linear drive module 31.

[0037] In one embodiment, such as Figures 1-6 As shown, each side panel is connected to the drive assembly 3 via two sets of side extension / retraction components 1. The two sets of extension / retraction components 1 connect the two sides of the side panel. The motor 33 is a geared motor, and the gearbox is equipped with output shafts on both sides. Correspondingly, two linear drive modules 31, two drive shafts 32, and two commutators 34 are provided. Power is transmitted to both sides through one motor 33 and two drive shafts 32, thereby synchronously driving the linear drive modules 31 on both sides to synchronously drive the two sets of side extension / retraction components 1 to synchronously control the extension and retraction of the side panel.

[0038] In one embodiment, such as Figures 1-6 As shown, the rear hatch is connected to the drive assembly 3 via two sets of rear extension / retraction components 2. Similarly, power is transmitted to both sides via a motor 33 and two drive shafts 32, thereby synchronously driving the linear drive modules 31 on both sides to synchronously drive the two sets of rear extension / retraction components 2 to synchronously control the expansion and contraction of the rear hatch.

[0039] The control logic of this utility model is as follows: Figures 1-6As shown, the deployment process is as follows: first, the left side panel is deployed, then the right side panel is deployed, and finally the aft panel is deployed. The retraction process is as follows: first, the aft panel is retracted, then the right side panel is retracted, and finally the left side panel is retracted.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Any modifications or equivalent substitutions to the present utility model without departing from the spirit and scope thereof should be covered within the protection scope of the claims of the present utility model.
