Description

A flipping device Technical Field

[0001] The present invention relates to the technical field of furniture, in particular to a turning device used for turning over furniture panels. Background Art

[0002] In the prior art, in order to improve indoor space utilization, some indoor tables or chairs have a folding function. For example, in the "Fixed Support Mechanism, Folding Mechanism and Folding Table" disclosed in Chinese Patent Application No. CN201410128026.4, a scissor-like structure is easily formed between the wall-mounted fixed frame and the table-top support frame during the folding process, and / or the wall-mounted fixed frame / table-top support frame / sliding support rod are easily formed into a scissor-like structure during the folding process, which is easy to cause injury to people's hands.

[0003] Another example is the "Wall-mounted Foldable Workbench" disclosed in Chinese patent application number CN202221254779.6. During the unfolding and folding process, the inner rod or the first connecting rod or the second connecting rod needs to be operated, which is complicated to operate and has poor stability. During use, it is easy to accidentally touch the inner rod or the first connecting rod and cause the workbench to fall over.

[0004] Another example is the "High-strength Wall-mounted Foldable Table" disclosed in Chinese patent application number CN201920864556.3, which also has the problem of requiring the operation of the support ribs during the unfolding and folding process, and the problem of easily accidentally touching the support ribs during use;

[0005] In addition, the above-mentioned folding tables or chairs can rotate the tabletop to open or close the tabletop. When the tabletop is in the open state, it can be used to place objects, and when the tabletop is in the folded state, it can save space. However, in the open state, the existing folding tables use a support mechanism to support the bottom of the tabletop. The support force is weak, resulting in a weak load-bearing capacity of the tabletop. When the tabletop is loaded with too many objects or when the user exerts force on the tabletop, the folding table is easily damaged, posing a danger to use. Moreover, when the tabletop is opened, the bottom support structure is exposed under the tabletop, which fails to meet people's demand for simple and beautiful furniture.

[0006] Patent application number US5816419A discloses a "removable, nestable display rack and inventory cart". The partition has a notch and a slot, and the bracket is provided with two pins. When the shelf is in a horizontal position, one of the pins is accommodated in the notch, and the other pin is slidably accommodated in the slot. It can be seen that the pins, notch and slot work together to limit the horizontal position of the shelf and prevent the shelf from moving downward from the horizontal position. However, the two pins mentioned above pass through the notch and slot horizontally, respectively, and the supporting performance is weak. When the partition is subjected to a large gravity load, the partition is easy to rotate downward, the stability is poor, and there is a risk of use. In addition, its supporting force acts only on both sides of the shelf, which easily causes the shelf to deform under load.

[0007] Summary of the Invention

[0008] In order to solve the technical problem of weak load-bearing capacity of the folding table or partition in the above-mentioned prior art, the present invention provides a turning device, comprising:

[0009] A frame, the frame comprising at least one support member, one end of the support member being adapted to be mounted on a component, the other end of the support member protruding from the component; or the frame being adapted to be mounted on a component, the frame being provided with at least one support member, at least a portion of which protrudes from the component;

[0010] and a plate body, wherein a plug-in channel extending in a front-to-back direction is formed on a front side surface of the plate body, so that the plate body can switch between an expanded state and a collapsed state relative to the frame body through the plug-in channel;

[0011] Wherein, the frame includes a first connecting portion, and the plate includes a second connecting portion;

[0012] When the plate body switches to the expanded state, at least a portion of the support member is inserted into the insertion channel, and the plate body is in a basically horizontal state; when the plate body switches from the expanded state to the folded state, the support member is moved out of the insertion channel, the first connecting portion and the second connecting portion are connected and cooperated with each other to keep the plate body connected to the frame body, and the plate body can be rotated downward so that the plate body is in a basically vertical state and even in the folded state.

[0013] Other technical solutions of the present invention are the same as the technical solutions described in claims 2 to 19 and will not be described in detail here.

[0014] Compared with the prior art, the flipping device of the present invention has the following advantages:

[0015] The frame or support is mounted on the component. When the panel is in the expanded state, the support is inserted into the insertion channel of the panel along the front-to-back direction. The support is inserted into the interior of the panel to limit the movement or rotation of the panel in the up-and-down direction, thereby supporting the panel and limiting its position in the up-and-down direction. At the same time, the contact area between the support and the panel is large, thereby increasing the load-bearing capacity of the panel. Since the support can limit the downward rotation of the panel after being inserted into the panel, limiting the rotation of the panel relative to the frame, the load-bearing capacity of the panel is increased, and the deformation of the panel under load is minimized or prevented. By inserting multiple support members into the insertion channels of the panel along the front-to-back direction, the support area of ​​the panel is increased, thereby improving the load-bearing capacity of the panel.

[0061] In the prior art, there are technical problems as described in the background art.

[0062] Example 1

[0063] In order to solve the above technical problems, please refer to Figures 1 to 39. Embodiment 1 of the present invention provides a flipping device, including a frame 1 and a plate 2. The frame 1 includes at least one support member 11, one end of the support member 11 is used to be installed on the component 5, and the other end of the support member 11 protrudes outside the component 5; or, the frame 1 is used to be installed on the component 5, and at least one support member 11 is provided on the frame 1, and at least a portion of the support member 11 protrudes outside the component 5. The front side of the plate body 2 is formed with an insertion channel 21 extending in the front-to-back direction, so that the plate body 2 can switch between the expanded state and the folded state relative to the frame body 1 through the insertion channel 21; wherein, the frame body 1 includes a first connecting portion 12, and the plate body 2 includes a second connecting portion 22; when the plate body 2 switches to the expanded state, a portion of the support member 11 is inserted into the insertion channel 21, and the plate body 2 is in a basically horizontal state; when the plate body 2 switches from the expanded state to the folded state, the support member 11 is moved out of the insertion channel 21, and the first connecting portion 12 and the second connecting portion 22 are connected and cooperated with each other to keep the plate body 2 connected to the frame body 1, and the plate body 2 can be rotated downward so that the plate body 2 is in a basically vertical state or even a folded state.

[0064] It should be noted that,. The component 5 can be a wall or furniture product or a load-bearing body in a home or office. One end of the support member 11 is mounted on the component 5 in a detachable or non-detachable manner, for example, it can be mounted on the component 5 by fasteners or glue or expansion bolts or other connectors, or a part of the support member 11 enters the component 5 and is fastened by expansion or interference. The other end of the support member 11 protrudes outside the component 5. As shown in Figures 1, 2, 15, 18, and 37, the plate body 2 is in a basically horizontal state, which means that the plate body 2 is parallel or nearly parallel to the ground, for example, the angle between the plate body 2 and the ground is -10° to 10°; as shown in Figures 3, 12, 20, 30, and 34, the plate body 2 is in a basically vertical state, which means that the plate body 2 is relatively vertical or nearly vertical to the ground, for example, the angle between the plate body 2 and the ground is 80° to 100°. The first connection portion 12 may be a part of the frame 1 , or a component or a structure mounted on the frame 1 ; the second connection portion 22 may be a part of the board 2 , or a component or a structure mounted on the board 2 .

[0065] For example, as shown in Figures 1 to 39, the up and down direction of this embodiment 1 may refer to the direction from top to bottom when the user is facing the frame 1, the left and right direction of this embodiment 1 may refer to the direction from left to right when the user is facing the frame 1, and the front and back direction of this embodiment 1 may refer to the direction from the end of the support 11 close to the component 5 to the end of the support 11 away from the component 5 (or when the plate body 2 is in a basically horizontal state, the direction from the end of the plate body 2 close to the component 5 to the end of the plate body 2 away from the component 5).

[0066] When the panel 2 is in the unfolded state, the support member 11 is inserted into the insertion channel 21 of the panel 2 along the front-to-back direction. The support member 11 is inserted into the interior of the panel 2 to limit the movement or rotation of the panel 2 in the up-and-down direction, supporting the panel 2 and limiting its position in the up-and-down direction. At the same time, the contact area between the support member 11 and the panel 2 is large, increasing the load-bearing capacity of the panel 2 and improving its load-bearing capacity. Since the support member 11 is inserted into the interior of the panel 2 along the front-to-back direction, the axis of downward rotation of the panel 2 relative to the frame 1 is along the left-right direction. Therefore, after the support member 11 is inserted into the panel 2, it can limit the downward rotation of the panel 2 and the rotation of the panel 2 relative to the frame 1, thereby increasing the load-bearing capacity of the panel 2. By inserting multiple support members 11 into the insertion channel 21 of the panel 2 along the front-to-back direction, the support area for the panel 2 is increased, thereby improving the load-bearing capacity of the panel 2 and reducing the deformation of the panel 2.

[0067] In this embodiment 1, one end of the support member 11 is fixed to the surface of the component 5 by an existing fastener, and the other end of the support member 11 protrudes from the component 5. Alternatively, one end of the support member 11 can be inserted into and locked inside the component 5, and the other end of the support member 11 protrudes from the component 5. The structure of the support member 11 is further described below.

[0068] In some embodiments, the support member 11 of this embodiment 1 includes a fastening portion 111 and a first supporting portion 112. The fastening portion 111 is mounted on the component 5, with at least a portion of the first supporting portion 112 protruding from the component 5. When the panel 2 is in the extended state, at least a portion of the first supporting portion 112 is inserted into the insertion channel 21, and the panel 2 is in a substantially horizontal position. When the panel 2 is in the collapsed state, the first supporting portion 112 is removed from the insertion channel 21, and the first connecting portion 12 and the second connecting portion 22 are connected, enabling the panel 2 to be in a substantially vertical position. The fastening portion 111 can be, for example, a flat or thin plate structure. The fastening portion 111 is secured to the component 5 using fasteners with high tensile strength, such as expansion bolts or explosive bolts. The fastening portion 111 can be fully or partially located within the component 5. By inserting the first supporting portion 112 into the insertion channel 21 of the panel 2, the panel 2 is supported and restrained in the vertical direction, thereby increasing the load-bearing capacity of the panel 2.

[0069] In some embodiments, as shown in Figures 2 and 6 to 9, the support member 11 of this embodiment 1 includes a fastening portion 111 and a first support portion 112, a portion of the fastening portion 111 is used to be installed on the component 5, and another portion of the fastening portion 111 protrudes from the component 5 to form a second support portion 113, and at least a portion of the first support portion 112 protrudes from the component 5. When the plate body 2 is in the expanded state, at least a portion of the second support portion 113 and the first support portion 112 are respectively inserted into the insertion channel 21, and the plate body 2 is in a basically horizontal state; when the plate body 2 is in the folded state, at least a portion of the second support portion 113 and the first support portion 112 are removed from the insertion channel 21, and the first connection portion 12 and the second connection portion 22 are connected and can make the plate body 2 in a basically vertical state. The first support portion 112 can be connected to or not connected to the second support portion 113. For example, when the first support portion 112 is not connected to the second support portion 113, the first support portion 112 and the second support portion 113 are spaced apart from each other. By simultaneously inserting the first support portion 112 and the second support portion 113 into the insertion channel 21 of the plate body 2, the plate body 2 is supported and limited in the up and down directions, thereby improving the load-bearing capacity of the plate body 2.

[0070] In some embodiments, the first support portion 112 and the second support portion 113 can be connected. For example, the support member 11 is an expansion bolt structure, and the support member 11 includes an expansion portion, a nut, and an external threaded portion that cooperates with the nut. The expansion portion forms the fastening portion 111, the nut and a portion of the external threaded portion form the second support portion 113, and a portion of the external threaded portion forms the first support portion 112. After the support member 11 of the expansion nut structure is fastened to the component 5, the portion of the support member 11 protruding from the component 5 forms the first support portion 112 and the second support portion 113 to be inserted into the interior of the plate body 2, supporting the plate body 2 and limiting it in the up and down directions. During installation, the expansion portion of the support member 11 is inserted into the interior of the component 5, and then the nut is rotated relative to the external threaded portion to expand the expansion portion outward and lock it to the component 5, thereby installing the support member 11 on the component 5.

[0071] In some embodiments, the support member 11 of this embodiment 1 includes a fourth support portion 114, which is connected to the first support portion 112. When the plate 2 is in the expanded state, at least a portion of the fourth support portion 114 is inserted into the insertion channel 21, and the plate 2 is in a substantially horizontal state. When the plate 2 is in the collapsed state, the fourth support portion 114 is removed from the insertion channel 21, the first connection portion 12 and the second connection portion 22 are connected, and the plate 2 is able to be in a substantially vertical state. The fourth support portion 114 and the first support portion 112 can be connected in a detachable or non-detachable manner. For example, the fourth support portion 114 is a sleeve structure, and the fourth support portion 114 is sleeved on the first support portion 112, thereby increasing the length of the support member 11 inserted into the plate 2, thereby improving the support force of the support member 11 on the plate 2. At the same time, the fourth support portion 114 and the first support portion 112 are removable from each other to improve the installation convenience of the support member 11 on the component 5.

[0072] In this embodiment 1, in order to improve the supporting effect of the support member 11 on the plate body 2, the support member 11 can be made of high-strength tensile-resistant metal material, that is, the fastening part 111, the first support part 112, the second support part 113 or the third support part and other components are all made of metal, thereby improving the overall structural strength of the support member 11.

[0073] In some embodiments, as shown in Figures 2, 8 to 11, 28, and 34, the frame 1 of this embodiment 1 further includes a guide member 13. The guide member 13 of this embodiment 1 includes a guide portion 131. The guide portion 131 extends through both the front and rear surfaces of the guide member 13. The support member 11 is connected to the component 5 through the guide portion 131. The guide portion 131 is used to guide the position between the fastening portion 111 and the component 5, and / or the guide member 13 is used to guide the position between the first support portion 112 and the insertion channel 21. For example, the guide member 13 can be attached to the component 5, the guide member 13 can be a flat plate or a thin plate structure, the guide portion 131 can be a through hole, a through groove, or a channel structure, and the fastening portion 111 passes through the guide portion 131 and is inserted into the interior of the component 5 and locked to accurately fix the frame 1 to the component 5. The central axis of the guide portion 131 can be perpendicular to the component 5, so that the drill bit can drill a hole in the component 5 substantially perpendicularly, so that the fastening portion 111 can be installed substantially perpendicularly on the component 5 after passing through the guide portion 131. This is used to guide the position between the fastening portion 111 and the component 5, improve the installation accuracy of the fastening portion 111 on the component 5, reduce the installation position error, and ensure that the support member 11 can be smoothly inserted into the insertion channel 21 of the plate body 2. And / or, the guide portion 131 can make the first support portion 112 substantially perpendicular to the component 5, and is used to guide the position between the first support portion 112 and the insertion channel 21, so that the first support portion 112 can be smoothly inserted into the insertion channel 21 of the plate body 2, or the second support portion 113 can be smoothly inserted into the insertion channel 21 of the plate body 2.

[0074] In some embodiments, as shown in Figures 10 and 11, the guide member 13 is provided with a guide protrusion 132 arranged circumferentially along the outer periphery of the guide portion 131. The guide protrusion 132 can be a convex point, a bump, or a convex wall structure. The guide protrusion 132 can allow a drill bit to pass through. By providing the guide protrusion 132 on the guide member 13, the length of the guide portion 131 is increased, and the accuracy and precision of the guide portion 131 in guiding the drill bit to drill a hole in the component 5 are further improved. As a result, after the support member 11 passes through the guide protrusion 132 and the guide portion 131, the fastening portion 111 can be substantially vertically mounted on the component 5. The guide protrusion 132 can be detachably connected to the guide member 13, such as by a threaded connection or a snap connection, or the guide protrusion 132 can be integrally formed with the guide member 13, such as by casting, drawing, or welding.

[0075] In some embodiments, when the panel 2 is in the extended state, at least a portion of the guide protrusion 132 is inserted into the insertion channel 21, and the panel 2 is in a substantially horizontal position. When the panel 2 is in the collapsed state, the guide protrusion 132 is removed from the insertion channel 21, the first connection portion 12 and the second connection portion 22 are connected, and the panel 2 is able to be placed in a substantially vertical position. The guide protrusion 132 is inserted into the insertion channel 21 of the panel 2 to form a third support portion, which provides support for the panel 2 in the extended state and improves the support force for the panel 2.

[0076] In this embodiment 1, the number of support members 11 is at least two, and adjacent support members 11 are spaced apart from each other, for example, the spacing between adjacent support members 11 is 15-30 cm, to improve the support effect on the plate body 2. Accordingly, in some embodiments, the number of guide portions 131 is at least two, and the at least two guide portions 131 are spaced apart in sequence along the left-right direction, for example, the spacing between adjacent guide portions 131 is 15-30 cm. The fastening portions 111 of the multiple support members 11 are respectively passed through the multiple guide portions 131 and installed on the component 5, thereby firmly mounting the frame 1 on the component 5.

[0077] In some embodiments, as shown in Figures 1 to 39, the frame 1 includes a shielding member 14, which can be flat or curved. At least a portion of the first support portion 112 is located within the top-down projection of the shielding member 14. For example, the entire first support portion 112 is located within the top-down projection of the shielding member 14. This prevents the user from viewing the first support portion 112 from above, thereby improving the overall aesthetics of the flip device. A relief portion 24 is formed on the front side of the plate 2 to ensure that the upper surface of the plate 2 in the unfolded state is on the same horizontal plane as the upper surface of the shielding member 14, thereby improving the overall aesthetics.

[0078] In some embodiments, as shown in Figures 1 to 3, 14 to 26, 30 to 32, and 36 to 39, the frame 1 includes a left side frame 15 and / or a right side frame 16, at least a portion of the left side frame 15 is disposed on the left side of the plate 2, and at least a portion of the right side frame 16 is disposed on the right side of the plate 2. For example, the frame 1 includes both the left side frame 15 and the right side frame 16, and the left side frame 15 and the right side frame 16 are spaced apart from each other in the left-right direction. For example, the left side frame 15 and the right side frame 16 are respectively provided with a first connecting portion 12, and the left and right sides of the plate 2 are respectively provided with a second connecting portion 22. The plate 2 is connected to the first connecting portion 12 via the second connecting portion 22 and is rotated downward relative to the frame 1 to a substantially vertical position. Furthermore, in some embodiments, the left side frame 15 and the guide member 13 are connected or the left side frame 15 and the guide member 13 are integrally formed; and / or, the right side frame 16 and the guide member 13 are connected or the right side frame 16 and the guide member 13 are integrally formed, so that the overall structure of the frame 1 is more solid and reliable. During installation, the guide member 13, the left side frame 15 and the right side frame 16 are installed together, which improves the installation efficiency.

[0079] In the present invention, this embodiment 1 does not limit the specific structures of the first connection part 12 and the second connection part 22. For example, the first connection part 12 can be a groove structure or a slide rail structure provided on the frame 1, and the second connection part 22 can be an axis structure provided on the plate body 2. The second connection part 22 is slidably provided on the first connection part 12 and can rotate relative to the first connection part 12. For another example, the first connection part 12 can be an axis structure provided on the frame 1, and the second connection part 22 can be a groove structure or a slide rail structure provided on the plate body 2. For another example, the first connection part 12 can be a rotating body structure provided on the support member 11, and the second connection part 22 can be a cavity structure provided on the insertion channel 21. The plate body 2 slides on the support member 11 through the insertion channel 21, and when the second connection part 22 on the plate body 2 moves to the first connection part 12, the plate body 2 can rotate downward relative to the frame body 1 through the first connection part 12 and the second connection part 22.

[0080] In some embodiments, as shown in Figures 33 and 34 , the end of the support member 11 away from the member 5 forms a first connection portion 12. When the panel 2 switches from the expanded state to the collapsed state, the support member 11 moves out of the insertion channel 21, and the front side of the panel 2 moves to the end of the support member 11 away from the member 5. The panel 2 rotates downward relative to the frame 1 to a substantially vertical position via the first connection portion 12 and the second connection portion 22.

[0081] In some embodiments, the second connection portion 22 is located in front of the insertion channel 21 near the front side of the plate body 2, and the support member 11 enters the insertion channel 21 through the second connection portion 22. The second connection portion 22 may be a groove or cavity structure, for example. When the front side of the plate body 2 moves to the end of the support member 11 away from the component 5, the plate body 2 rotates downward relative to the frame body 1 to a substantially vertical position via the first connection portion 12 and the second connection portion 22.

[0082] In some embodiments, the first connecting portion 12 includes a rotating portion 121, and the second connecting portion 22 includes a rotating cavity 221 that rotates in conjunction with the rotating portion 121. The rotating portion 121 and the rotating cavity 221 can switch the plate body 2 between a substantially horizontal state and a substantially vertical state. The rotating portion 121 can be connected to the support member 11, or the rotating portion 121 and the support member 11 form an integrated structure. At least a portion of the rotating portion 121 is spherical or has a surface arc shape, and the structure of the rotating cavity 221 matches the structure of the rotating portion 121. For example, the rotating cavity 221 is a spherical or hemispherical chamber, so that the rotating portion 121 rotates relative to the rotating cavity 221 within the rotating cavity 221.

[0083] In some embodiments, the flipping device of this embodiment 1 further includes a mounting block 23, which is formed with a rotation cavity 221. The mounting block 23 is embedded in the plate body 2 and is located at the opening of the plug-in channel 21 on the front side of the plate body 2. The rotation cavity 221 is connected to the plug-in channel 21, and one end of the support member 11 is sequentially inserted into the rotation cavity 221 and the plug-in channel 21. A groove structure is provided on the plate body 2 to cooperate with the mounting block 23. The mounting block 23 can be installed on the plate body 2 by fasteners. The material of the mounting block 23 can be a wear-resistant material such as metal or hard plastic. By adding the mounting block 23 with the rotation cavity 221 to the plate body 2, the wear-resistant mounting block 23 can improve the rotation stability and smoothness of the rotating part 121 in the rotation cavity 221, thereby improving the stability of the plate body 2 relative to the frame body 1.

[0084] The working principle of the flipping device of this embodiment 1 is as follows: when the plate body 2 switches from the folded state to the unfolded state, an external force acts on the plate body 2 in a basically vertical state, and the first connecting part 12 and the second connecting part 22 rotate relative to the frame body 1, so that the plate body 2 rotates upward to a basically horizontal position, and then drives the plate body 2 to slide horizontally and gradually approach the component 5, and inserts the support member 11 into the insertion channel 21 of the plate body 2 in the front and rear directions, and utilizes the support member 11 to support the plate body 2, thereby improving the load-bearing capacity of the plate body 2. When the plate body 2 switches from the expanded state to the folded state, the external force drives the plate body 2 to translate relative to the frame body 1 in the direction away from the component 5, and causes the support member 11 to gradually move out of the insertion channel 21. When the front end of the insertion channel 21 of the plate body 2 moves to the end of the support member 11 away from the component 5, or when the plate body 2 translates to a predetermined position, the first connecting portion 12 and the second connecting portion 22 are connected to each other to enable the plate body 2 to rotate downward relative to the frame body 1, so that the plate body 2 rotates to a basically vertical state and even a folded state.

[0085] In some embodiments, as shown in Figures 2 to 32, the board body 2 is provided with a reinforcement 6, which is close to the front end of the front side of the board body 2 and forms an insertion channel 21. The reinforcement 6 can be a metal part or other hard material, and the board body 2 can usually be made of wood. By adding a reinforcement 6 with greater strength to the inside of the board body 2, when the board body 2 is subjected to a gravity load, the support member 11 will not cause damage or deformation to the board body 2, and the damage or deformation of the board body 2 by the support member 11 is reduced, thereby further improving the load-bearing capacity of the board body 2.

[0086] In some embodiments, the rear end of the reinforcement 6 away from the front side of the plate body 2 is provided with an external threaded portion, and the reinforcement 6 is connected to the plate body 2 through threads to improve the stability of the reinforcement 6 inside the plate body 2, wherein the cross-section of the insertion channel 21 of the reinforcement 6 is hexagonal or plum blossom-shaped, and the reinforcement 6 can be installed in the plate body 2 after the plate body 2 is inserted into the insertion channel 21.

[0087] Example 2

[0088] The flipping device of this embodiment 2 is further described based on the flipping device of the above-mentioned embodiment 1. As shown in Figures 14 to 32, the flipping device of this embodiment 2 also includes a limit assembly 3, which locks the board 2 in the extended state through the limit assembly 3, preventing or reducing the board 2 from switching to the retracted state due to user error, further improving the stability and safety of the board 2.

[0089] Among them, the limit component 3 of this embodiment 2 can switch between a locked state and an unlocked state. When the board body 2 is in the expanded state, the limit component 3 can switch to the locked state so that the board body 2 cannot be switched to the folded state; and, the limit component 3 can switch to the unlocked state so that the support member 11 can be moved out of the insertion channel 21, and the board body 2 is flipped downward relative to the frame body 1 and switched to the folded state.

[0090] In some embodiments, as shown in Figures 14 to 32, the position limiting assembly 3 of this embodiment 2 includes a locking member 31. The locking member 31 cooperates with or separates from the frame 1 or the plate 2 to switch the position limiting assembly 3 between a locked state and an unlocked state. The present invention does not limit the location of the locking member 31. For example, the locking member 31 can be provided on the frame 1, the plate 2, or the component 5. Specifically, when the locking piece 31 is provided on the frame 1 or the component 5, the limiting assembly 3 also includes a first locking space 32 provided on the plate body 2, and the locking piece 31 can enter the first locking space 32. When the plate body 2 switches from the expanded state to the retracted state, at least a portion of the locking piece 31 can abut against the plate body 2, and is connected with the plate body 2 through the locking piece 31, so that the limiting assembly 3 enters the locked state; when the locking piece 31 is provided on the plate body 2, the limiting assembly 3 also includes a second locking space (not shown in the figure) provided on the frame 1 or the component 5, and the locking piece 31 can enter the second locking space. When the plate body 2 switches from the expanded state to the retracted state, at least a portion of the locking piece 31 can abut against the frame body 1 or the component 5, and is connected with the frame body 1 or the component 5 through the locking piece 31, so that the limiting assembly 3 switches to the locked state.

[0091] It should be noted that the first locking space 32 can be formed in a slot structure on the plate body 2, or the first locking space 32 can be a space defined between a portion of the plate body 2 and the second connecting portion 22 (for example, the first connecting portion 12), or the first locking space 32 can be the surface of the plate body 2. Similarly, the second locking space can be formed in a slot structure on the frame body 1 or the component 5, or the second locking space can be a space defined between a portion of the frame body 1 and the first connecting portion 12, or the second locking space can be the surface of the frame body 1 or the component 5.

[0092] When the locking member 31 is disposed on the frame 1 or the component 5, at least a portion of the locking member 31 can abut against the plate 2 or the second connection portion 22 of the plate 2, thereby locking the position limiting assembly 3. When the locking member 31 is disposed on the plate 2, at least a portion of the locking member 31 can abut against the frame 1 or the component 5 or the first connection portion 12 of the frame 1, thereby locking the position limiting assembly 3.

[0093] In some embodiments, when the locking member 31 is provided on the frame 1 or the component 5, the limiting assembly 3 also includes a first locking space 32 provided on the plate body 2, and at least a portion of the locking member 31 can enter the first locking space 32. When the plate body 2 is translated from the expanded state to the folded state, at least a portion of the locking member 31 can abut against the second connecting portion 22, and the locking member 31 is connected to the second connecting portion 22 through cooperation, so that the limiting assembly 3 enters the locked state; or, when the locking member 31 is provided on the plate body 2, the limiting assembly 3 also includes a second locking space provided on the frame 1, and at least a portion of the locking member 31 can enter the second locking space; when the plate body 2 is translated from the expanded state to the folded state, at least a portion of the locking member 31 can abut against the first connecting portion 12, and the locking member 31 is connected to the first connecting portion 12 through cooperation, and the limiting assembly 3 enters the locked state.

[0094] In particular, this embodiment 2 does not limit the movement of the locking member 31. For example, the locking member 31 can enter the first locking space 32 or the second locking space by sliding or rotating, and can also enter the first locking space 32 or the second locking space by sliding and rotating. In some embodiments, the locking member 31 includes a first locking portion 311, which enters the first locking space 32 or the second locking space by sliding or rotating. After entering the first locking space 32, the first locking portion 311 abuts against the plate 2, or after entering the second locking space, the first locking portion 311 abuts against the frame 1, so that the limit assembly 3 switches to the locked state. Referring to Figures 14-19 and 24-29, the locking member 31 is mounted on the plate 2, the frame 1, or the component 5 in a removable or positionally adjustable manner, such as by threaded connection or sliding connection. When the plate 2 is adjusted to the expanded state, the locking member 31 can be mounted on the plate 2, the frame 1, or the component 5, or the position of the locking member 31 can be adjusted so that the first locking portion 311 of the locking member 31 is placed within the first locking space 32 or the second locking space, thereby restricting the plate 2 from switching to the retracted state. In addition, referring to Figures 27-29, the locking member 31 can also lock the plate 2 after switching to the retracted state, preventing the plate 2 from swinging freely in the retracted state.

[0095] In some embodiments, the locking member 31 further includes a first operating portion 312, which is used to allow an external force to drive the first locking portion 311 into the first locking space 32 or the second locking space, thereby causing the limiting assembly 3 to enter a locked state; or the first operating portion 312 is used to allow an external force to drive the first locking portion 311 out of the first locking space 32 or the second locking space, thereby causing the limiting assembly 3 to enter an unlocked state. The first operating portion 312 is used to provide an external force application point, and the external force acts on the first operating portion 312 to cause the first locking portion 311 to displace (stretch, press, move, rotate, or otherwise move), thereby causing the first locking portion 311 to enter or leave the first locking space 32 or the second locking space.

[0096] In some embodiments, the locking member 31 further includes a first elastic member 313. The first elastic member 313 is capable of driving the first locking portion 311 into and retaining it in the first locking space 32 or the second locking space, thereby placing the limiting assembly 3 in a locked state. When the first locking portion 311 enters the first locking space 32 or the second locking space, the locking member 31 is in the first state; when the first locking portion 311 leaves the first locking space 32 or the second locking space, the locking member 31 is in the second state. The first elastic member 313 is connected to the locking member 31. The first elastic member 313 may be, for example, a spring or a tension spring. The first elastic member 313 can drive the first locking portion 311 into the first locking space 32 or the second locking space by tension or compression. When the locking member 31 is in the second state, a portion of the first locking portion 311 may still be in the first locking space 32 or the second locking space, but not abutting the plate 2 or the frame 1.

[0097] In some embodiments, the locking member 31 further includes a first limiting portion 314, which is used to limit the locking member 31 from switching from the second state to the first state, thereby maintaining the locking assembly 3 in the unlocked state. The first limiting portion 314 can be connected to the first operating portion 312 or the first locking portion 311. When the first limiting portion 314 is in a preset position, the first limiting portion 314 can cooperate with the plate 2, the frame 1, the component 5, or other external components to maintain the preset position, so that the first limiting portion 314 can limit the locking member 31 from switching from the second state to the first state, thereby maintaining the locking assembly 3 in the unlocked state. In some specific embodiments, the first limiting portion 314 can be, for example, a protrusion or a protruding ring structure protruding from the first operating portion 312. When the first limiting portion 314 abuts against the plate 2, the frame 1, or the component 5, the first limiting portion 314 can limit the locking member 31 from switching from the second state to the first state.

[0098] In some embodiments, as shown in FIG12 and FIG13, the flipping device of this embodiment 2 further includes a buffer mechanism 4, which is used to buffer the plate body 2 when it is able to rotate downward from the expanded state to the folded state. The buffer mechanism 4 is, for example, a hydraulic buffer or a spring buffer. The buffer can be installed on the plate body 2 or the frame 1 or the component 5. When the base of the buffer is installed on the frame 1, the telescopic end of the buffer is connected to the plate body 2, so that when the plate body 2 rotates to a substantially vertical state relative to the frame 1, the buffer has a buffering effect on the rotating plate body 2, preventing the plate body 2 from rotating too fast due to inertial rotation or causing damage to the plate body 2 after the plate body 2 hits the frame 1 or the component 5.

[0099] Example 3

[0100] The flipping device of this embodiment 3 is similar to the flipping device of the aforementioned embodiment 2, except that, as shown in FIG35 , the first operating portion 312 of the flipping device of this embodiment 3 includes a first guiding bevel 312a. The plate 2 or the frame 1 can act on the first guiding bevel 312a, thereby placing the locking member 31 in the second state. The first operating portion 312 and the first locking portion 311 can be the same component, that is, the first guiding bevel 312a is formed on the first locking portion 311. When the plate 2 or the frame 1 acts on the first guiding bevel 312a of the first locking portion 311 (equivalent to the plate 2 or the frame 1 acting on the first operating portion 312), the first locking portion 311 is driven to move, thereby leaving the first locking space 32 or the second locking space. When the plate body 2 is moved in the expansion direction, the plate body 2 or the frame body 1 is able to act on the first guide inclined surface 312a and switch the locking member 31 from the first state to the second state. At the same time, the locking member 31 compresses or stretches the first elastic member 313 so that the first elastic member 313 generates elastic potential energy. When the plate body 2 continues to move in the expansion direction, the plate body 2 or the frame body 1 passes over the first locking portion 311 and makes a part of the plate body 2 or a part of the frame body 1 located in front of the first locking space 32. The first elastic member 313 releases the elastic potential energy and drives the locking member 31 to move so that the locking member 31 switches from the second state to the first state, so that the limit assembly 3 is in the locked state. When the plate body 2 is moved in the folding direction, the first locking portion 311 can block at least a part of the plate body 2 or at least a part of the frame body 1 so that the plate body 2 cannot switch to the folded state.

[0101] Example 4

[0102] The flipping device of this embodiment 4 is similar to the flipping device of the aforementioned embodiment 2, except that, as shown in Figures 36 to 39, the limiting assembly 3 of the flipping device of this embodiment 4 further includes a second limiting portion 36, which is capable of abutting against the first limiting portion 314 to maintain the limiting assembly 3 in the unlocked state. When the first limiting portion 314 is driven to move relative to the plate 2, the frame 1, or the component 5, the first limiting portion 314 and the second limiting portion 36 abut against each other, restricting the locking member 31 from switching from the second state to the first state, thereby maintaining the limiting assembly 3 in the unlocked state.

[0103] When the first limiting portion 314 is provided on the plate body 2, the second limiting portion 36 is provided on the plate body 2. The first limiting portion 314 may be a protruding structure, and the second limiting portion 36 may be a protruding structure mounted on the plate body 2 or a part of the plate body 2. The first limiting portion 314 is slidably and rotatably provided on the plate body 2. For example, the plate body 2 may be provided with a channel for the first limiting portion 314 to pass through, and the first limiting portion 314 may be able to slide and rotate within the channel. When an external force drives the first limiting portion 314 to slide and rotate within the channel, the first limiting portion 314 may abut against the second limiting portion 36, and the second limiting portion 36 limits the movement of the first limiting portion 314, thereby limiting the locking member 31 from switching from the second state to the first state, so that the limiting assembly 3 is in the unlocked state. When the first operating portion 312 drives the first locking portion 311 to enter or leave the first locking space 32 or the second locking space, the first operating portion 312 can drive the first limiting portion 314 to rotate so that the second limiting portion 36 and the first limiting portion 314 come into contact. In addition, the first limiting portion 314 can also be a groove, and the second limiting portion 36 can be a movable component mounted on the plate body 2. When an external force drives the locking member 31 to switch from the first state to the second state, the second limiting portion 36 can be driven to be placed in the groove. At this time, the second limiting portion 36 can restrict the locking member 31 from switching from the second state to the first state, so that the limiting assembly 3 remains unlocked.

[0104] For another example, when the first stopper 314 is provided on the frame 1 or the component 5, the second stopper 36 is provided on the frame 1 or the component 5. Based on the same principle, the first stopper 314 can be a protrusion, and the second stopper 36 can be a protrusion mounted on the frame 1 or the component 5, or a part of the frame 1 or the component 5; alternatively, the first stopper 314 can be a groove, and the second stopper 36 can be a movable component mounted on the plate 2.

The first connecting portion 12 of this embodiment 5 includes a first matching portion 122, and / or the second connecting portion 22 includes a second matching portion (not shown in the figure). The first matching portion 122 and the second matching portion can be connected and matched to each other so that the plate body 2 and the frame body 1 remain connected to each other and enable the plate body 2 to rotate downward so that the plate body 2 is in a basically vertical state or even a folded state. It can be understood that in the first specific embodiment, the first connecting portion 12 includes the first matching portion 122, and the second connecting portion 22 cooperates with the first matching portion 122 to connect so that the plate body 2 can rotate downward so that the plate body 2 is in a basically vertical state or even a folded state. In the second specific embodiment, the second connecting portion 22 includes the second matching portion, and the first connecting portion 12 cooperates with the second matching portion to connect so that the plate body 2 can rotate downward so that the plate body 2 is in a basically vertical state or even a folded state. In the third specific embodiment, the first connecting portion 12 includes a first matching portion 122, and the second connecting portion 22 includes a second matching portion. The first matching portion 122 and the second matching portion can be connected and matched to keep the plate body 2 and the frame body 1 connected to each other and enable the plate body 2 to rotate downward so that the plate body 2 is in a basically vertical state or even a folded state.

[0108] In some embodiments, as shown in Figures 14 to 32 and Figures 35 to 39, the first connecting portion 12 includes a first slot 123 extending in the front-to-back direction, a first mating portion 122 is disposed at the rear end of the first slot 123, and at least a portion of the second connecting portion 22 is movably disposed within the first slot 123. When at least a portion of the second connecting portion 22 moves to the rear end of the first slot 123 and abuts the first mating portion 122, the first mating portion 122 and at least a portion of the second connecting portion 22 are connected, allowing the plate body 2 to rotate downward, placing the plate body 2 in a substantially vertical position, or even in a retracted position. The first mating portion 122 can be a groove or slot structure, communicating with the rear end of the first slot 123, and the second connecting portion 22 can be a rotating shaft or pivot structure, so that the second connecting portion 22 is connected to the first mating portion 122, allowing the plate body 2 to rotate downward to a substantially vertical position, or even in a retracted position.

[0109] In some embodiments, the frame 1 includes a left frame 15 and a right frame 16, which are arranged with relative spacing left and right in the horizontal direction; the frame 1 is provided with two first grooves 123, which are respectively provided on the left frame 15 and the right frame 16, and the two first grooves 123 are opposite to each other, and the plate body 2 is provided with two second connecting parts 22, which are respectively provided on the left and right sides of the plate body 2, and at least a part of the two second connecting parts 22 is respectively adapted to the two first grooves 123.

[0110] In some embodiments, the longitudinal section of at least a portion of the second connecting portion 22 is T-shaped, and the first groove 123 is adapted to at least a portion of the second connecting portion 22, thereby increasing the lateral tension between the plate and the frame and improving the stability of the plate when flipping.

[0111] As the second mating connection method, the second connection part 22 includes a second mating part. The movement principle of the mutual mating connection between the first connection part 12 and the second mating part can refer to the movement principle between the above-mentioned first mating part 122 and the second connection part 22, and the details are omitted here.
