It should be noted that the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
Referring to fig. 1 to 2, the invention provides a folding storage ceiling, which comprises a hoisting assembly, a keel 1, a ceiling, a telescopic device 2 and a linkage assembly; the keel 1 is hoisted at the bottom of the hoisting assembly; the two groups of ceilings are respectively arranged on two sides of the keel 1, and one side of the ceilings, which is close to the keel 1, is hinged with the keel 1; the telescopic device 2 extends along the vertical direction and is arranged at the top of the keel 1, the end part of the telescopic rod is provided with a flange 5, and the flange 5 is in transmission connection with the ceiling through a linkage assembly, so that the ceiling is driven to be unfolded or folded when the telescopic device 2 performs telescopic motion.
The invention has the greatest characteristics that the automatic opening and closing functions of the ceiling can be realized, and the ceiling can be automatically opened or folded by simple control. Normally, the telescopic device 2 is in a contracted state, and the ceiling is also in a horizontally opened state, which is no different from a common suspended ceiling product.
When the telescopic device 2 is controlled to be driven to push and stretch, the ceiling can be driven to fold through the linkage assembly, automatic folding storage is achieved, after storage, a person can observe the actual situation of the area above the ceiling, even the person can directly climb into the space above the ceiling, and operations such as overhaul and maintenance can be conveniently carried out. The ceiling-folded ventilating and lighting effect can be realized in building rooms with special structures such as patio and skylight. In general, the telescopic device 2 is preferably a device such as an electric cylinder or an air cylinder which facilitates control of the telescopic operation, and the electric cylinder is more suitable as the telescopic device 2 in view of easier searching of the power supply in a general room.
According to different structures of the linkage assembly, the invention is divided into a single-folded structure and a double-folded structure, and in the embodiment, the single-folded structure is described first:
preferably, each group of ceilings is provided with only the first ceiling unit 3, and the linkage assembly comprises a main connecting rod 4, one end of the main connecting rod 4 is hinged with a flange 5 of the telescopic device 2, and the other end is hinged with the middle part of the first ceiling unit 3.
The single-folding structure is simple, the linkage assembly is only a main connecting rod 4, the telescopic device 2 and the first ceiling unit 3 form a sliding block rocker mechanism, the telescopic device 2 is used as a driving piece, and the main connecting rod 4 drives the first ceiling unit 3 to swing, so that the opening and folding are controlled.
The structure is dimensioned with a high degree of freedom, but also needs to follow certain constraints. The following is a corresponding derivation of the geometric relationships of the components:
referring to fig. 2, first, when the ceiling is opened, the first ceiling unit 3 is horizontally laid, i.e., is in right angle with the vertically arranged telescopic device 2. The main connecting rod 4 is obliquely connected between the middle hinging point of the first ceiling unit 3 and the flange 5 of the telescopic device 2 to form a right triangle, thus, the length L of the main connecting rod 4 is set 1 Length L between the hinge point of the first ceiling unit 3 with the keel 1 and the middle hinge point of the first ceiling unit 3 2 The basic length a of the telescopic device 2 and the top extension stroke S of the telescopic device 2 necessarily satisfy the following conditions: l (L) 1 >A,L 1 >L 2
Meanwhile, in the folded and stored state, the telescopic device 2 is fully extended, the first ceiling unit 3 swings upwards, and maintains a small angle with the telescopic device 2, generally within 20 degrees, and the telescopic device 2 and the main connecting rod 4 maintain a small angle, namely, the triangle formed by the telescopic device 2, the main connecting rod 4 and the first ceiling unit 3 is an obtuse triangle at the moment, so that L is necessarily satisfied 1 +L 2 >A+S。
In addition, L 1 And L is equal to 2 The formulation of (2) is carried out according to the specific parameters A and S of the telescopic device 2, and the formulation is desirable on the premise of selecting the proper telescopic device 2L is calculated 1 And L is equal to 2 . Let the included angle between the main connecting rod 4 and the telescopic device 2 be theta 1 The included angle between the first ceiling unit 3 and the telescopic device 2 is theta 2 A+s=l 1 cosθ 1 +L 2 cosθ 2 . In the open state, θ 2 =90°, s=0, so a=l 1 cosθ 1 The method comprises the steps of carrying out a first treatment on the surface of the In the folded storage state, θ 1 、θ 2 Are very small, so L at this time 1 cosθ 1 The numerical value is obviously increased to meet the L 1 cosθ 1 >A, at this time if it is still required to satisfy a+s=l 1 cosθ 1 +L 2 cosθ 2 Then inevitably satisfy L 2 cosθ 2 <S, due to theta in this state 1 、θ 2 Are all very small, so L 2 cosθ 2 ≈L 2 Therefore, to realize the folding function, it is preferable to ensure that L is satisfied 2 <S。
Under the condition that the above condition is satisfied, L can be freely formulated 1 And L is equal to 2 Is a specific length of (c).
Example two
In this embodiment, a two-fold structure will be described in detail. Referring to fig. 3 to 4, in particular, each set of ceilings is preferably provided with a first ceiling unit 3 adjacent to the keel 1, and a second ceiling unit 6 hinged to the first ceiling unit 3; the first ceiling unit 3 is hinged with the second ceiling unit 6 at a joint, and one side of the first ceiling unit 3, which is close to the keel 1, is hinged with the keel 1; the linkage assembly comprises a main connecting rod 4, an auxiliary connecting rod 7 and a swinging rod 8; one end of the main connecting rod 4 is hinged with a flange 5 of the telescopic device 2, and the other end is hinged with the middle part of the first ceiling unit 3; the bottom end of the swing rod 8 is rigidly fixed on the top edge of the second ceiling unit 6, so that the swing rod 8 is fixedly protruded out of the top of the second ceiling unit 6; one end of the auxiliary connecting rod 7 is hinged with the middle part of the main connecting rod 4, and the other end of the auxiliary connecting rod 7 is hinged with the top end of the swing rod 8.
This configuration is a specific configuration of the linkage assembly improved so as to extend the two fold configuration on the basis of the first embodiment. In spite of the two-fold structure, the geometrical relationship between the main link 4 and the first antenna element 3 still satisfies the derivation described in the first embodiment.
With this structure, the outer half part of the first ceiling unit 3, the main link 4, the auxiliary link 7 and the swing link 8 form a four-bar mechanism, and when the main link 4 and the first ceiling unit 3 are linked, the swing link 8 is driven to swing. Because the swing rod 8 is rigidly and fixedly connected with the second ceiling unit 6, the second ceiling unit 6 swings correspondingly when the swing rod 8 swings. In order to ensure a stable connection between the second ceiling unit 6 and the pendulum 8, it is preferred that said pendulum 8 is triangular with its base rigidly fixed to the ceiling unit's top edge remote from the keel 1.
Likewise, the parts of the four-bar mechanism are sized with a high degree of freedom, but also follow certain geometrical constraints. Referring to fig. 4, a length L between a middle hinge point of the first ceiling unit 3 and a joint of the second ceiling unit 6 is set 3 Length L between the middle hinge point of the main link 4 to the hinge point of the bottom end thereof and the first ceiling unit 3 4 When the four-bar mechanism acts, in order to avoid the collision and death of the auxiliary connecting rod 7 and the outer side edge of the first ceiling unit 3, the geometric relationship should be satisfied: l (L) 3 <L 4 . Or the auxiliary connecting rod 7 is modified into an upward arched arc or fold line shape by adopting a mode of improving the structure of the auxiliary connecting rod 7, so that the auxiliary connecting rod 7 is prevented from being collided with the outer side edge of the first ceiling unit 3.
The folding storage ceiling provided by the invention is powered by the telescopic device 2, and the linkage assembly drives the ceiling to realize an automatic opening and closing function, so that the ceiling can be folded and stored, a space is emptied for overhauling, observation and entering, and the ceiling can be stored for ventilation, light transmission and the like. According to the different structure of the linkage assembly, the two structural schemes of single folding and double folding are divided, so that different requirements are met. And easy installation and maintenance, high reliability, and no influence on the appearance of the product because all mechanisms are collected above the ceiling.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
