Description

Technical Field

[0001] The present invention relates to a folding table plate structure, and more specifically, to an electric folding hidden table plate, which can be installed and used on the side walls and seat backs of trains, airplanes, various vehicles, etc. Background Art

[0002] As people's work pace continues to accelerate, the workload continues to increase, and people are traveling more and more. Working in the office can no longer meet people's needs, especially when people encounter emergencies at work on the road, they urgently need a mobile office to deal with difficult problems at work. In order to meet people's needs and improve the riding comfort of passengers, in the prior art, a table that can be folded open is usually set on the back of the seat or the side of the armrest of a car or other means of transportation to provide office space and place various items. Generally speaking, the structure of the seat table on existing cars, high-speed trains and airplanes is relatively simple. These small tables are generally hinged on the back of the seat at one end, and the other end can be freely rotated to a horizontal state for passengers to place various items or use for office and rest. When not in use, they can be folded and stored to avoid affecting passengers' entry and exit.

[0003] However, the existing small table on the back of the seat is usually exposed on the back of the seat and cannot be hidden, which not only affects the overall aesthetics of the seat, but also poses a certain safety hazard to passengers. In addition, such folding table generally does not have a large load-bearing capacity and is easily damaged when placing heavy items. Moreover, folding or unfolding is mostly done manually, which is not convenient to use. Summary of the invention

[0004] 1. Technical problem to be solved by the invention

[0005] The purpose of the present invention is to overcome the above-mentioned shortcomings of the existing folding table tops and to provide an electric folding hidden table top. By adopting the technical solution of the present invention, the table top assembly is automatically stored or unfolded in the storage box through a driving mechanism. After storage, the structure is compact and occupies little space. After unfolding, the table top assembly automatically flips to a horizontal state. The design is ingenious and easy to use. In the process of extending and retracting the table top assembly, rollers are used to reduce the friction of the table top assembly, thereby effectively avoiding the wear on the surface of the table top assembly. In addition, two rollers are used to support the unfolded table top assembly. The table top has a stronger load-bearing capacity and is more practical. It can be widely used in the side walls and backs of seats of trains, airplanes and various vehicles.

[0044] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments.

[0045] Example

[0046] Combination Figures 1 to 7As shown, an electric folding hidden table top in the present embodiment comprises a storage box 1, a driving mechanism 2 and a table top assembly 3. A storage space is provided in the storage box 1 for accommodating the above-mentioned table top assembly 3, and an opening is left at the upper portion of the storage box 1, and a first roller 1-3 is provided at the opening; the driving mechanism 2 is used to drive the table top assembly 3 to extend upward from the upper opening of the storage box 1, and the bottom of the table top assembly 3 is rotatably connected to the driving mechanism 2. When the driving mechanism 2 drives the table top assembly 3 to extend out from the storage box 1, the table top assembly 3 flips to a horizontal state in the direction of the first roller 1-3, and the back of the table top assembly 3 is supported on the first roller 1-3. In this way, the table board assembly 3 can be automatically stored or unfolded in the storage box 1 through the driving mechanism 2. After being stored, the structure is compact and occupies little space. After being unfolded, the table board assembly 3 automatically flips to a horizontal state. The design is ingenious and easy to use. In addition, during the extension and retraction process of the table board assembly 3, the friction of the table board assembly 3 is reduced by using the first roller 1-3, thereby effectively avoiding the wear on the surface of the table board assembly 3, making the extension and retraction of the table board assembly 3 more stable and quiet, and the operation is more stable. It can be widely used in the side walls and backs of seats of trains, airplanes and various vehicles. In order to make the table board assembly 3 always flip in the direction of the first roller 1-3 when extending, it is preferred that the rotation axis between the table board assembly 3 and the driving mechanism 2 is biased toward the front of the table board assembly 3, so that the center of gravity of the table board assembly 3 is slightly biased toward the back of the table board assembly 3, and then the table board assembly 3 is always flipped in the direction of the first roller 1-3.

[0047] like Figure 3 , Figure 5 and Figure 7 As shown, in this embodiment, a second roller 1-4 parallel to the first roller 1-3 is also provided at the upper opening of the storage box 1. A channel for the table board assembly 3 to be extended and retracted is reserved between the second roller 1-4 and the first roller 1-3. The position of the second roller 1-4 is relatively upward and backward relative to the first roller 1-3. When the table board assembly 3 is flipped to a horizontal state in the direction of the first roller 1-3, the front bottom of the table board assembly 3 is against the second roller 1-4. The cooperation of the first roller 1-3 and the second roller 1-4 can further reduce the wear on the surface of the table board assembly 3 on the one hand, and improve the bearing capacity of the table board on the other hand, making it more practical. When the table board assembly 3 is under pressure, the first roller 1-3 supports the table board assembly 3, while the second roller 1-4 presses down the table board assembly 3, reducing the force on the rotation connection position between the bottom of the table board assembly 3 and the drive mechanism 2, so that it can withstand greater weight. Both ends of the first roller 1-3 and the second roller 1-4 are mounted on the storage box 1 through bearings and can rotate flexibly.

[0048] like Figures 1 to 7As shown, in order to make the electric folding hidden table top more neat and beautiful after folding and storage, in this embodiment, the table top assembly 3 includes a table top body 3-1, and a cover plate 3-3 is provided on the top of the table top body 3-1. After the table top assembly 3 is retracted into the storage box 1, the cover plate 3-3 closes the upper opening of the storage box 1 (such as Figure 2 and Figure 3 As shown in the figure, the opening of the storage box 1 can be closed by the cover plate 3-3, making the electric folding table top more neat and beautiful after storage. In addition, in order to facilitate the installation and disassembly of the table top body 3-1, in this embodiment, the bottom of the table top assembly 3 is rotatably connected to the driving mechanism 2 through a bottom rod 3-2, and the bottom rod 3-2 is detachably connected to the bottom of the table top body 3-1 of the table top assembly 3. The detachable table top structure facilitates the installation and disassembly of the table top body 3-1, facilitates the replacement of the table top body 3-1, and is more flexible and convenient to manufacture. Specifically, as Figure 8 As shown, both ends of the bottom rod 3-2 are provided with plug blocks 3-2-1, and the bottom of the table top body 3-1 is provided with a socket corresponding to the position of the above-mentioned plug block 3-2-1. The plug blocks 3-2-1 and the sockets of the table top body 3-1 are also provided with screw holes with corresponding positions. The plug block 3-2-1 is inserted into the socket and is fastened by screws 3-2-2. The structure is simple and the connection is firm.

[0049] Continue Figures 1 to 7As shown, in this embodiment, the driving mechanism 2 includes two sets of lead screw nut transmission mechanisms respectively arranged on both sides of the storage box 1 and a motor 2-1 for synchronously driving the two sets of lead screw nut transmission mechanisms. The lead screws 2-3 in the lead screw nut transmission mechanisms are vertically installed on the sides of the storage box 1, and both sides of the bottom of the table board assembly 3 are respectively rotatably connected to the nuts 2-4 in the two sets of lead screw nut transmission mechanisms. The driving mechanism 2 uses the lead screw nut transmission mechanism to drive the table board assembly 3 to expand and contract. The transmission is stable and reliable, the table board expands and contracts smoothly, the transmission efficiency is high, the transmission accuracy and positioning accuracy are high, the service life is long, and the running noise is small. In addition, the nuts 2-4 in the two sets of lead screw nut transmission mechanisms are connected by a light shaft. The light shaft is inserted into the round holes of the nuts 2-4 on both sides, so that the light shaft can freely rotate on the nuts 2-4 on both sides. The bottom rod 3-2 in the table board assembly 3 is of a hollow structure, and the bottom rod 3-2 is sleeved on the above-mentioned light shaft. The rotation connection structure is adopted between the table board main body 3-1 and the driving mechanism 2, which is simple to manufacture, flexible to rotate, and can effectively ensure the synchronization of the lifting of both sides of the table board main body 3-1. Preferably, the above-mentioned motor 2-1 is a double-headed motor. The motor 2-1 is arranged at the bottom of the storage box 1, and the output shafts at both ends of the motor 2-1 are respectively传动连接 to the lead screws 2-3 in the two sets of lead screw nut transmission mechanisms through worm and worm gear reducers 2-2. The table board assembly 3 has good lifting self-locking property and good transmission synchronization, ensuring stable expansion and contraction of the table board, and having a compact structure and small occupied space. In addition, in this embodiment, the storage box 1 includes a frame 1-1 and a surrounding board 1-2 that forms a box body on the frame 1-1. The surrounding board 1-2 on the front can be used as a decorative surface. It is better that the cross-sections of the upright rods on both sides of the frame 1-1 are in a "U" shape, and the opening directions of the two upright rods are opposite. The above-mentioned lead screw nut transmission mechanism is arranged inside the upright rods, and such a structure is simpler and more compact. Moreover, a limiting block 1-5 for positioning the table board assembly 3 is also arranged at the bottom of the storage box 1 when the table board assembly 3 contracts into the storage box 1. Through the storage box 1, the table board assembly 3 can be hidden, without occupying space, and the limiting block 1-5 can be used to stably position the table board assembly 3 in the storage box 1, effectively avoiding abnormal noises generated by the shaking of the table board assembly 3 in the storage box 1. In order to reduce the overall weight of the folding table board, the frame 1-1, the surrounding board 1-2 and the cover board 3-3 of the storage box 1 are all made of aluminum alloy material.

[0050] Figure 2 and Figure 3 is a schematic diagram of the folding state of the electric folding hidden table board. As shown in the figure, the driving mechanism 2 drives the table board assembly 3 to contract into the storage box 1. At this time, the bottom rod 3-2 in the table board assembly 3 abuts against the limiting block 1-5 at the bottom of the storage box 1, so that the free end of the table board assembly 3 abuts against the second roller 1-4, effectively preventing the table board assembly 3 from shaking. And at this time, the cover board 3-3 at the top of the table board assembly 3 closes the upper opening of the storage box 1, thus forming as Figure 2 (注:原文中“传动连接”处英文表述缺失,已用“传动连接 to”表示需要补充完整准确的英文连接词)The very thin box structure shown is neat and beautiful and does not take up space. Figure 4 and Figure 5 This is a schematic diagram of the semi-extended state of the electric folding hidden table top. As shown in the figure, the driving mechanism 2 drives the table top assembly 3 to extend outward from the storage box 1. At this time, the table top assembly 3 automatically tilts toward the first roller 1-3 under the action of gravity, and extends outward along the first roller 1-3 while flipping toward the first roller 1-3. The higher the extension height, the greater the flipping angle. Since the first roller 1-3 can rotate freely, the rolling friction between the table top assembly 3 and the first roller 1-3 is small, the friction resistance is small, the wear on the surface of the table top assembly 3 is small, and there is no friction noise. Figure 6 and Figure 7 It is a schematic diagram of the unfolded state of the electric folding hidden table top. As shown in the figure, when the driving mechanism 2 drives the table top assembly 3 to be fully extended, the table top assembly 3 is flipped to a horizontal use state. At this time, the first roller 1-3 is supported on the back of the table top assembly 3, and the second roller 1-4 is pressed on the front of the table top assembly 3, and the position is biased to the rear, so that the table top assembly 3 can be fixed in a horizontal position, and when the table top assembly 3 is load-bearing, the first roller 1-3 and the second roller 1-4 can play a very good supporting role, thereby improving the load-bearing capacity of the table top assembly 3 and preventing it from being damaged easily.

[0051] The back of the storage box 1 of the electric foldable hidden table in this embodiment is fixedly mounted on the side wall of a vehicle or the back of a seat, and can be used as a table. Fig. 9 As shown in FIG. 1 , it is a schematic diagram of the structure of the electric folding hidden table installed on the seat back. Fig.10 As shown, it is a schematic diagram of the structure of an electric folding hidden table installed on the side wall of a vehicle. When in use, a button that is convenient for passengers to operate can be installed near the electric folding hidden table. The lifting stroke of the table assembly 3 in the storage box 1 is set by the built-in program. When the button is pressed, the table assembly 3 extends from the storage box 1 to a horizontal use state. When the button is pressed again, the table assembly 3 shrinks and folds into the storage box 1 and is hidden. The above-mentioned vehicles can be various types of cars, trains (such as high-speed trains, EMU trains), airplanes, luxury cruise ships, etc. Of course, the electric folding hidden table of this embodiment is not limited to use on the above-mentioned vehicles, nor is it limited to being installed on the side walls or seat backs. It can also be used in environments such as homes and shopping malls, such as walls and wall hangings in narrow spaces.

[0052] The present invention provides an electric foldable hidden table top. The table top assembly is automatically folded or unfolded in a storage box through a driving mechanism. After folding, the structure is compact and occupies little space. After unfolding, the table top assembly automatically flips to a horizontal state. The design is ingenious and easy to use. In the process of extending and retracting the table top assembly, rollers are used to reduce the friction of the table top assembly, thereby effectively avoiding wear on the surface of the table top assembly. In addition, two rollers are used to support the unfolded table top assembly. The table top has a stronger load-bearing capacity and is more practical. It can be widely used on the side walls and backs of seats of trains, airplanes and various vehicles.

[0053] The present invention and its embodiments are described schematically above, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and creatively designs a structure and an embodiment similar to the technical solution without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
