In one embodiment, the two ends of the horizontal shaped sliding rail 312 are provided with a first limiting device and a second limiting device for limiting the lower end of the carriage cover driving device 320, so as to prevent the carriage cover driving device 320 from being separated from the contact with the horizontal shaped sliding rail 312.
In one embodiment, as shown in fig. 8-9, the horizontal shaped sliding track 312 comprises a frame structure including a bottom wall 313, a top wall 314, and a first side wall 316 and a second side wall 315 connecting the bottom wall 313 and the top wall 314 at both ends, the top wall 314 forming the horizontal portion 3141 and the sloped portion 3142. Wherein the bottom wall 313 is slidably connected to the rail 112 to enable the horizontal shaped sliding rail 312 to move along the rail 112.
In one embodiment, as shown in fig. 8, the rail 112 includes a bottom plate 1121, risers 1123, and a top plate 1122, the top plate 1122 preferably having a horizontal configuration on its surface. The vertical plates 1123 connect the bottom plate 1121 with the top plate 1122, one or two accommodating spaces 1124 (for example, a C-shaped or i-shaped cross section) are formed between the top plate 1122 and the bottom plate 1121, a guide wheel structure 330 is fixedly connected to the lower side of one or both sides of the bottom wall 313 of the horizontal profiled sliding rail 312, the guide wheel structure 330 includes a support frame 331 and a roller 332, the support frame 331 is accommodated in the accommodating space 1124, and the roller 332 can be in rolling contact with the side walls of the accommodating space 1124, for example, the lower surface of the top plate 1122, the upper surface of the bottom plate 1121, and the side surfaces of the vertical plates 1123. With such an arrangement, the horizontal profiled sliding rail 312 can smoothly move on the rail 112.
In one embodiment, as shown in fig. 8-9, the lower end 323 of the vertical moving member 321 is in rolling connection with the top wall 314 of the horizontal shaped sliding rail 312.

By adopting the scheme, the vertical moving piece 321 is simultaneously connected with the upper surface and the lower surface of the top wall 314 in a rolling manner, so that the horizontal special-shaped sliding rail 312 drives the vertical moving piece 321 more smoothly. In this embodiment, since the bottom wall 313, the top wall 314 and the two side walls are frame-shaped structures, the movement of the vertical moving member 321 is limited within the frame-shaped structure, that is, the first side wall 316 constitutes the first stopper, the second side wall 315 constitutes the second stopper, when the inner cylinder 200 is in the retracted state, the vertical moving member 321 is at the lowest position of the top wall 314, at this time, the side surface of the vertical moving member 321 contacts the first side wall 316, and can only move upward along the inclined surface, but cannot move in the opposite direction, and the first side wall 316 constitutes a first stopper for limiting the vertical moving member 321. Similarly, when the inner cylinder 200 is in the vertical state, the vertical moving member 321 is at the end of the horizontal portion 3141 of the top wall 314, and at this time, the side surface of the vertical moving member 321 contacts the second side wall 315, and only moves along the horizontal portion 3141 in the direction of the inclined surface, but not in the opposite direction, and the second side wall 315 forms a second stopper for limiting the vertical moving member 321. By adopting the scheme, an additional limiting part is not required to be arranged independently, the structure is simplified, the cost is saved, and meanwhile, the function is not lost.
In one embodiment, when the inner cylinder 200 is erected to 9 °, the vertical moving member 321 moves to the boundary between the slope portion 3142 and the horizontal portion 3141. With this arrangement, when the inner cylinder 200 is erected to 9 °, the compartment cover 120 is already fully opened, and the rear moving compartment cover 120 is always kept in an opened state. When the inner cylinder 200 is retracted, the compartment cover 120 is firstly kept in an open state, and when the rising angle is reduced to 9 degrees, the compartment cover 120 starts to be closed, so that the contact between the inner cylinder 200 and the compartment cover 120 is ingeniously avoided.
Specifically, as shown in FIGS. 10-11, in one example, the shape of the cam surface is calculated as follows.
L-horizontal distance from vertical hinge point of inner cylinder to front end of inner cylinder
a is the vertical distance from the highest point of the inner cylinder to the vertical hinge point of the inner cylinder
b-vertical distance from the highest point of the inner cylinder to the compartment cover
Beta-included angle between the connecting line of the highest point of the front end of the inner cylinder and the vertical hinged point and the horizontal plane
Gamma is the maximum erecting angle of the carriage cover without interference with the inner cylinder in the erecting process, the erecting of the inner cylinder of 9 degrees can be obtained through the calculation of the formula, the inner cylinder is stably erected to ensure that the carriage cover is stably opened, and the carriage cover is opened by uniform rotation. Motion analysis is carried out on the horizontal crank sliding block mechanism, each component is expressed as a vector, and a closed vector equation is listed as follows:

θ 2 the included angle between the first connecting rod and the horizontal plane;
derived by
s＝l 1 cosθ 1 +l 2 cosθ 2

Wherein

s 0 -initial value of s, i.e. t =0, when θ 1 ＝θ 0 。
And in the same way, the motion analysis is carried out on the vertical crank-slider mechanism, and the vertical profile of the cam is deduced as follows:

X-the vector of the rotating hinge point of the carriage cover to the hinge point of the vertical sliding part is horizontally projected
The front part of the horizontal special-shaped cam slide rail is a special-shaped cam, the wheel calculates the horizontal displacement and the vertical displacement of the special-shaped cam according to the formula, obtains the relation between the horizontal displacement and the vertical displacement of the special-shaped cam along with time, and combines the two curves to obtain the relation between the horizontal profile and the vertical profile of the cam, namely the shape of the special-shaped cam. By adopting the scheme, the optimum shape of the cam can be calculated according to the actual parameter condition, the opening time of the compartment cover is effectively shortened, and the occurrence of interference is reduced.
In one embodiment, the desired compartment cover 120 is a flexible member, and the remaining compartment bodies 110 are fixedly connected. With such a scheme, the opening and closing of the carriage cover 120 can be conveniently achieved by utilizing the flexibility of the carriage cover 120, and an additional hinge element is not required to be arranged between the carriage cover 120 and the carriage body 110.
In one embodiment, multiple sets of the lid driving device 320 are disposed in the car body 110, for example, four sets are disposed on two sides of the inner tube 200. A corresponding number of horizontal profiled slide rails 312 are provided within the box. Preferably, the plurality of horizontal shaped sliding rails 312 on each side are fixedly connected to each other, so that the plurality of horizontal shaped sliding rails 312 on one side can be driven by one first connecting rod 311 to move synchronously on the rail 112, and thus the horizontal shaped sliding rails 312 on both sides can be driven synchronously by two first connecting rods 311 which are symmetrically arranged. By adopting the scheme, the problem that the plurality of horizontal special-shaped sliding rails 312 drive the corresponding vertical moving parts 321 asynchronously respectively is avoided, particularly, the heights of the inner barrel 200 at the same angle and different positions are different, and if the plurality of first connecting rods 311 are respectively used for driving, the problem that the horizontal special-shaped sliding rails 312 cannot be driven to be coordinated accurately and the same can be caused. By adopting the scheme, the opening of a plurality of parts of the compartment cover 120 can be synchronized, and the opening efficiency is improved.
In one embodiment, the position of the first link 311 is calculated according to the length and height of the inner tube 200 and the height of the closed compartment cover 120. Specifically, it needs to be ensured that when the upper edge of the end of the inner cylinder 200 far from the hinge point approaches the carriage cover 120, the connecting rod drives the horizontal special-shaped slide rail 312 to move, so that the carriage cover driving device 320 moves to drive the carriage cover 120 to open.
In one embodiment, a ratio of a hinge point 201 of the inner cylinder 200 and the car body to a length of the first link 311 relative to a distance between a hinge point 3111 of the first link 311 and the inner cylinder 200 is 1: (1.3-2.1). More preferably, when the inner cylinder 200 is in the retracted state, a ratio of a hinge point 3112 of the first link 311 and the horizontal shaped sliding rail 312 to a length of the first link 311 relative to a distance between the hinge point of the inner cylinder 200 and the carriage body is (1.1-1.2): 1. By adopting the scheme, the acting force of the first connecting rod 311 on the horizontal opposite-shaped sliding rail is reasonably separated in the horizontal and vertical directions in the process of erecting the inner barrel 200. Specifically, at the beginning of erecting, the acting force of the inner cylinder 200 on the first link 311 is substantially consistent with the extending direction of the first link 311, so that unnecessary shaking at the beginning is avoided, and the force distribution enables the horizontal acting force of the first link 311 on the horizontal shaped sliding rail 312 to be large enough, so that the horizontal shaped sliding rail 312 can move rapidly along the rail 112. In the process of erecting, the angle of the first link 311 with respect to the horizontal direction is gradually increased, so that the horizontal component force of the first link 311 on the horizontal irregular shaped slide rail 312 is gradually reduced, the moving speed of the horizontal irregular shaped slide rail 312 is reduced, and the last link of opening the compartment cover 120 can be slower by matching the shape of the cam surface. In addition, the size ratio enables the horizontal movement of the first link 311 to be small after the compartment cover 120 is opened, so that the length of the horizontal portion 3141 of the horizontal special-shaped slide rail 312 can be shortened, and the problems of material waste and interference of installation spaces of a plurality of horizontal special-shaped slide rails 312 due to the overlarge size of the horizontal special-shaped slide rail 312 are avoided.
In one embodiment, the roller 324 is a resilient roller 324. Preferably, in a natural state, the distance between the upper roller 324 and the lower roller 324 is less than the thickness of the top wall 314. More preferably, the upper rollers 324 include four sets arranged in a rectangular shape, the lower rollers 324 are provided in at least two sets and are arranged symmetrically to the upper rollers 324, and preferably, the lower rollers 324 are provided in four sets. During the installation process, the top wall 314 enables the elastic roller 324 to be compressed, and the tension generated by the elastic roller 324 firmly fixes the vertical moving member 321 on the horizontal special-shaped sliding rail, so as to prevent the vertical moving member from shaking. Under this kind of structure, need not to set up the guide of vertical moving member 321 on the carriage body, simplified the structure of the carriage body to nimble the position that sets up of horizontal dysmorphism slide rail 312, can adapt to the demand of not unidimensional inner tube 200.
