Therefore, it is necessary to develop and design a lightweight wall panel mechanism to reduce weight and ease the difficulty of unhooking. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and to develop a lightweight wall panel mechanism that reduces labor intensity and locking difficulty.

[0004] To achieve the above objectives, the lightweight wall panel mechanism of this utility model is used to protect the inner sides of a passageway. Its main structure includes a flexible arc-shaped rectangular central plate and a frame set along its long side, a cover plate set along its short side, and several cables set along its back. Several locking components are set on the front of one frame and a guide plate is set on the back (called the locking side frame). Hooks and several fastening holes are set on the back of the other frame (called the non-locking side frame). Alternatively, several locking components are set on the front of both frames and guide plates are set on the back of both frames.

[0005] The main structure of the locking assembly includes a lock cover and a lock cylinder installed inside it; the lock cover is installed on the frame by a locking nut, the lock cylinder is installed inside the lock cover by a rubber ring, a locking washer is provided between the locking nut and the frame, and the inner end face of the lock cover is a bevel.

[0006] In addition, a support component is provided at the center of the lower edge of the center plate.

[0007] In order for the center plate to bend, at least one (preferably three) cable is installed between the frame edges. The cable pretensions the center plate so that it is already arched in the initial position and ensures that it continues to arch in the same direction as the vehicles move relative to each other.

[0008] The present invention relates to a lightweight wall panel mechanism in which the lower edge and upper edge move in parallel during use, and the deformation is distributed almost evenly on the cover plate.

[0009] Once opened, the support components provide support, preventing damage to the cover plate at the lower edge.

[0010] When the vehicle turns, the center plate is stretched on the outside of the turn and compressed on the inside. The tension of the cable allows it to continue arching in the same direction during the turn and return to the starting position immediately after the turn without exceeding the starting position.

[0011] Compared with the prior art, this utility model includes at least a flexible center plate, a frame, a cover plate, a guide plate, a locking assembly, a support assembly, and a cable. Two frame plates are fixed to the long side of the center plate, and two cover plates are fixed to the short side of the center plate. The cover plates are made of rubber, which can absorb the height difference between the front and rear vehicles and effectively prevent damage to the center plate. The guide plate is fixed to the locking side frame and has a guiding function. The locking assembly is fixed through the locking side frame and is evenly arranged in the height direction. The support mechanism is fixed at the center of the short side of the bottom of the center plate. After the center plate is opened, it supports the cover plate against the vehicle floor, protecting it from excessive pressure. The seat plate at the contact point between the support assembly and the vehicle floor is non-metallic, effectively preventing damage to the vehicle floor. The two ends of the cable are fixed to the two frame plates respectively. The length of the cable under tension ensures that the center plate is always in a bent state, creating a region with high rigidity and load-bearing capacity, compensating for the elongation or shortening of the wall panel mechanism during relative vehicle movement.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1:

[0021] The main structure of a lightweight wall panel mechanism involved in this embodiment is as follows: Figure 1-4As shown, it includes a center plate 510, a frame 511, a cover plate 512, a pull cable 513, a locking assembly 514, a guide plate 515, fastening holes 5112, hooks 517, and adhesive 518. The arc-shaped center plate 510 has a frame 511 on its long side, a cover plate 512 on its short side, and three pull cables 513 on its back. One frame 511 has three locking assemblies 514 on its front and a guide plate 515 on its back. The other frame 511 has hooks 517 and several fastening holes 5112 on its back. The center plate 510 and the frame 511 are connected by a plug-in joint, and adhesive 518 is applied to the joint. The pull cables 513, locking assemblies 514, and fastening holes 5112 are evenly spaced.

[0022] Furthermore, the main structure of the locking mechanism 514 includes a lock cover 5141, a locking nut 5142, a lock cylinder 5143, a rubber ring 5144, a locking washer 5145, and an inclined surface 5147; the lock cover 5141 is mounted on the frame 511 by the locking nut 5142, the lock cylinder 5143 is mounted inside the lock cover 5141 by the rubber ring 5144, the outer end is flush with the lock cover 5141, and the inner end extends out of the lock cover 5141; a locking washer 5145 is provided between the locking nut 5142 and the frame 511; and the inner end face of the lock cover 5141 is an inclined surface 5147.

[0023] In addition, a support component 53 is provided at the bottom center of the center plate 510. The main structure of the support component 53 includes a base plate 530 and a support plate 531 with a V-shaped structure provided on it. The top of the support plate 531 is provided with bolt holes 532 so as to be connected to the center plate 510 by fasteners 100.

[0024] The central plate 510 involved in this embodiment has the characteristics of high strength and high fire resistance. It includes a thermosetting plate made of synthetic resin and reinforced with glass fiber fabric felt, which meets the requirements of EN45545 standard. The connection between the central plate 510 and the frame 511 is bonded and fixed by applying adhesive 518. When an information carrier plate for displaying information (including passenger information or advertising information) is set on the outer side of the central plate 510, a transparent plastic plate is set on the outermost side so that the information carrier plate (e.g., printed poster) between the plastic plate and the central plate 510 can be clearly seen. The plastic plate can both fix the information carrier plate and protect it from external influences.

[0025] The frame 511 is a lightweight metal strip with a duckbill-shaped connector;

[0026] The cover plate 512 is made of elastic rubber, which is deformable and can absorb some vertical displacement.

[0027] Three parallel cables 513 pre-tension the center plate 510, causing the center plate 510 to be compressed or bent, and to be arc-shaped in the initial position.

[0028] The locking assembly 514 is fixed to the frame 511 through the hole, and the fastening hole 5112 is also through the frame 511, which facilitates connection with other components.

[0029] The lightweight wall panel mechanism involved in this embodiment weighs less than 20 kg and is assembled and handled separately, meeting the requirements for one-time hoisting or assembly, and satisfying the specification requirement for one-person operation. The assembly process is as follows:

[0030] First, a frame 511 is connected to the part to be connected by passing a fastening element through a fastening hole 5112. With the help of the positioning function of the hook 517, the fastening element can be easily installed.

[0031] Then, move another frame 511 to another component to be connected, and quickly connect the component to be connected by locking assembly 514 with the help of the guide plate 515;

[0032] Finally, use a tool to rotate the lock cylinder 5143, so that the lock cylinder 5143 is screwed into or out of the lock seat on the part to be connected, to connect and separate. The interaction between the inner wall and the inclined surface 5147 inside the lock cover 5141 and the rubber ring 5144 can prevent the lock cylinder 5143 from coming out when it is unlocked and ensure centering during the connection process.
