Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a limiting component used for turning over furniture panels; the utility model also relates to a turning device. Background Art

[0002] In the prior art, in order to improve indoor space utilization, some indoor tables or chairs have a folding function, such as the "Fixed Support Mechanism, Folding Mechanism and Folding Table" disclosed in Chinese Patent Application No. CN201410128026.4, the "Wall-Mounted Foldable Workbench" disclosed in Chinese Patent Application No. CN202221254779.6, and the "High-Strength Wall-Mounted Foldable Table" disclosed in Chinese Patent Application No. CN201920864556.3. Among them, the "High-Strength Wall-Mounted Foldable Table" disclosed in Chinese Patent Application No. CN201920864556.3 requires the operation of support ribs during the unfolding and folding process. When the table is in the unfolded state, the user may accidentally touch the support ribs and switch the table to the folded state, which may cause objects on the table to fall off.

[0003] To this end, the prior art has employed latches or pins added to the folding mechanism or support ribs to achieve locking of the table, thereby improving the stability and safety of the table in the unfolded state. However, when switching the table from the unfolded state to the folded state, the latch or pin must be manually pulled out while the table must be pulled. This makes it difficult for the user to simultaneously pull out the latch or pin and pull the table when the table is long, resulting in a cumbersome and laborious operation. Furthermore, when the table is switched back from the folded state to the unfolded state, the latch or pin must be re-inserted into the folding mechanism or support ribs, resulting in a cumbersome operation and poor intelligence, which reduces the user experience. Utility Model Content

[0004] In order to solve the technical problems in the prior art of using latches or pins to lock folding tables, which are cumbersome to operate and have poor intelligence, the first aspect of the present invention provides a limit assembly, comprising:

[0005] a moving member, at least a portion of which is capable of sliding and / or rotating to form a motion path, wherein the motion path includes a locking position;

[0006] a locking member, the locking member comprising a first locking portion, a first elastic member, and a first limiting portion, wherein the first locking portion can enter the movement path through the first elastic member; and

[0007] an unlocking mechanism, a portion of which is disposed within the motion path, the unlocking mechanism comprising a third limiting portion, the third limiting portion cooperating with the first limiting portion;

[0008] When at least a portion of the moving member slides and / or rotates in a predetermined direction to the locking position, the first locking portion enters the movement path through the first elastic member, and the first locking portion abuts against at least a portion of the moving member to restrict the moving member from sliding and / or rotating in a direction opposite to the predetermined direction.

[0009] When external force drives the first locking part to leave the movement path, the first limiting part cooperates and abuts with the third limiting part to maintain the first locking part away from the movement path, at least a part of the moving part can slide and / or rotate in the opposite direction to the predetermined direction, and at least a part of the moving part can abut against the unlocking mechanism to drive the third limiting part to separate from the first limiting part, so that the first locking part enters the movement path through the first elastic part.

[0010] Compared with the prior art, the limit assembly of the present invention has the following beneficial effects:

[0011] The movable member can be applied to the first member, and the locking member and the unlocking mechanism are applied to the second member. The two members can move relative to each other. When the first member is in use, the movable member moves to the locked position, and the first locking portion of the locking member automatically enters the motion path and abuts against the movable member through the first elastic member, limiting the relative movement of the two members, thereby achieving a locking effect on the first member. When the relative position between the two members needs to be adjusted, the user drives the first locking portion to leave the motion path by manual or other external force, and adjusts the locking member to a preset position. The third limiting portion of the unlocking mechanism cooperates with the first limiting portion of the locking member to abut against each other to maintain the first locking portion away from the motion path and separated from the movable member. At this time, the user can release the hand controlling the first locking portion (or locking member), making it easier for the user to pull or drive the first member to move, so that the unlocking and pulling of the first member do not need to be performed simultaneously, and the operation is more convenient and easy. And when the first component moves relative to the second component, at least a part of the moving part can abut against the unlocking mechanism to control the third limiting part to separate from the first limiting part, thereby releasing the locking effect of the first locking part, so that the first locking part enters the movement path under the drive of the first elastic part, so that the first locking part can automatically lock the moving part when the first component is adjusted back to the use state, and there is no need to readjust the position of the first locking part, reducing the number of adjustments to the first locking part, thereby improving the convenience and intelligence of operation and enhancing the user experience.

[0012] In some embodiments, the first locking portion is formed with a first guide surface; when the movable member slides and / or rotates along the predetermined direction to the locked position, at least a portion of the movable member can act on the first guide surface, driving the first locking portion away from the motion path, thereby causing the movable member to slide and / or rotate to the locked position. This design eliminates the need for the user to actively control the movement of the locking member, simplifying the operation steps and improving the user experience.

[0013] In some embodiments, the unlocking mechanism further comprises a second elastic member; when an external force drives the first locking portion to leave the motion path, the second elastic member drives the third limiting portion to slide and / or rotate, causing the third limiting portion to engage with the first limiting portion to maintain the first locking portion away from the motion path. With this design, when the third limiting portion and the first limiting portion are positioned correspondingly, the third limiting portion and the first limiting portion automatically form an abutment fit and stably maintain the abutment state, thereby stably maintaining the limiting assembly in the unlocked state.

[0014] In some embodiments, the unlocking mechanism includes a first limiting member, a portion of the first limiting member forms the third limiting portion, and a portion of the first limiting member is located within the motion path to form a first unlocking portion;

[0015] When the moving member slides and / or rotates to the position of the first unlocking portion in a direction opposite to the predetermined direction, at least a portion of the moving member drives the first unlocking portion to move, driving the third limiting portion to separate from the first limiting portion, so that the first locking portion enters the movement path through the first elastic member.

[0016] Under this design, it can be ensured that after the movable part is no longer restricted by the locking part, the movable part can be used to drive the first limiting part to move, thereby changing the state of the locking part, so that the limiting component can switch between the locked state and the unlocked state by itself. In this way, the user does not need to specifically adjust the state of the locking part, which reduces the operation difficulty and improves the user experience.

[0017] In some embodiments, the unlocking mechanism includes:

[0018] a first limiting member, wherein one end of the first limiting member forms the third limiting portion, and the other end of the first limiting member forms a second operating portion;

[0019] an unlocking member, the unlocking member comprising a third operating portion and a second unlocking portion, the third operating portion being disposed within the motion path, the second unlocking portion cooperating with the second operating portion;

[0020] In which, when the moving member slides and / or rotates to the position of the second unlocking portion in a direction opposite to the predetermined direction, at least a part of the moving member drives the second unlocking portion to move, thereby driving the second unlocking portion to drive the second operating portion to move, and the second operating portion drives the third limiting portion to separate from the first limiting portion, so that the first locking portion enters the movement path through the first elastic member.

[0021] Under this design, it can be ensured that after the movable part is no longer restricted by the locking part, the unlocking part is driven to move by the movable part, and then the first limiting part is driven to move by the unlocking part, thereby changing the state of the locking part, so that the limiting component can switch between the locked state and the unlocked state by itself. In this way, the user does not need to specifically adjust the state of the locking part, which reduces the operation difficulty and improves the user experience.

[0022] In some embodiments, the third operating portion includes a fourth guide surface; when the movable member slides and / or rotates in the opposite direction of the predetermined direction, at least a portion of the movable member can act on the fourth guide surface to drive the third operating portion to move, thereby driving the second unlocking portion to drive the second operating portion to move, and the second operating portion drives the third limiting portion to separate from the first limiting portion, so that the first locking portion enters the movement path through the first elastic member. The fourth guide surface can be an inclined plane or an inclined arc surface. When at least a portion of the plate body or at least a portion of the frame body or at least a portion of the component acts on the fourth guide surface and moves on the fourth guide surface, the unlocking member will move smoothly, thereby driving the first limiting member to move, so that the locking member is restored to the first state under the action of the first elastic member.

[0023] In some embodiments, the second operating portion includes a second guide surface, and the second unlocking portion can act on the second guide surface to drive at least a portion of the first limiting member to move, so that the third limiting portion and the first limiting portion no longer abut against each other, thereby allowing the first locking portion to enter the movement path through the first elastic member; and / or, the unlocking portion includes a third guide surface, and the third guide surface can abut against the second operating portion to drive at least a portion of the first limiting member to move, so that the third limiting portion and the first limiting portion no longer abut against each other, thereby allowing the first locking portion to enter the movement path through the first elastic member. The second guide surface and the third guide surface can be inclined planes or inclined arc surfaces. Under the cooperation of the unlocking portion and the second guide surface or the third guide surface and the second operating portion or the second guide surface and the third guide surface, the unlocking portion can smoothly drive the first limiting member to move.

[0024] In some embodiments, the unlocking mechanism further includes a third elastic member connected to the unlocking member; when at least a portion of the movable member passes through the third operating portion, the third elastic member drives the third operating portion into the motion path. This prevents the unlocking member from exerting excess force on the first limiting member, ensuring that the second elastic member can drive the first limiting member to move to the third limiting portion to engage with the first limiting portion.

[0025] In some embodiments, the locking member further includes a first operating portion, configured to allow an external force to drive the first locking portion away from the motion path. The first operating portion provides a point of application for an external force, and the external force acts on the first operating portion to cause the first locking portion to displace (stretch, press, move, rotate, or otherwise move), thereby adjusting the operating state of the limit assembly.

[0026] In some embodiments, the first operating portion includes an operating handle, which can drive the first locking portion away from the motion path when an external force acts on the operating handle. The operating handle is designed to be easy for the user to grasp, allowing the user to better control the movement of the locking member.

[0027] In addition, the second aspect of the present invention provides a flipping device, comprising a frame, a plate, and the limiting assembly as described above;

[0028] The movable member is provided on the plate body or the movable member and the plate body are integrally formed, and at least a portion of the movable member slides and / or rotates relative to the frame body so that the plate body switches between the deployed state and the retracted state; or the movable member is provided on the frame body or the movable member and the frame body are integrally formed, and at least a portion of the movable member slides and / or rotates relative to the plate body so that the plate body switches between the deployed state and the retracted state;

[0029] When at least a portion of the moving member moves to the locking position along a predetermined direction, the plate body switches to the expanded state, the first locking portion enters the movement path through the first elastic member, and the first locking portion abuts against at least a portion of the moving member to restrict the moving member from sliding and / or rotating in a direction opposite to the predetermined direction;

[0030] When external force drives the first locking part to leave the movement path, the first limiting part cooperates and abuts with the third limiting part to maintain the first locking part away from the movement path, at least a part of the moving part can slide and / or rotate in the opposite direction to the predetermined direction, and at least a part of the moving part can abut against the unlocking mechanism to drive the third limiting part to separate from the first limiting part, so that the first locking part enters the movement path through the first elastic part, and the plate body can switch to the retracted state.

[0031] Compared with the prior art, the flipping device of the present invention has the following beneficial effects:

[0032] The plate body slides and / or rotates relative to the frame body through the moving member, so that the plate body can switch between the expanded state and the folded state. When the plate body switches to the expanded state, the moving member moves to the locking position, and the first locking portion of the locking member automatically enters the motion path and abuts against the moving member through the first elastic member, limiting the plate body from sliding and / or rotating toward the folded state, thereby achieving a locking effect on the plate body, so that the plate body in the expanded state is safe and reliable. When the plate body needs to be switched from the expanded state to the folded state, the user manually drives the first locking portion to leave the motion path, and after adjusting the locking member to a preset position, the third limiting portion of the unlocking mechanism cooperates with the first limiting portion of the locking member to abut to maintain the first locking portion away from the motion path and separated from the moving member. At this time, the user can release the hand that controls the first locking portion (or locking member), making it convenient for the user to pull or drive the plate body to slide and / or rotate toward the folded state, so that the unlocking and pulling of the plate body do not need to be performed synchronously, and the operation is more convenient and easy. And when the plate body slides and / or rotates toward the folded state, at least a portion of the movable part can abut against the unlocking mechanism to control the third limiting part to separate from the first limiting part, thereby releasing the locking effect of the first locking part, so that the first locking part enters the movement path under the drive of the first elastic part, so that the first locking part can automatically lock the movable part when the plate body switches to the expanded state again, and there is no need to readjust the position of the first locking part, reducing the number of adjustments to the first locking part, thereby improving the convenience and intelligence of operation and enhancing the user experience.

[0033] In some embodiments, the frame includes at least one support member, one end of which is used to be mounted on the component, and the other end of which protrudes from the component; or, the frame is used to be mounted on the component, the frame is provided with at least one support member, and at least a portion of the support member protrudes from the component;

[0034] The front side of the plate body is formed with an insertion channel extending in the front-to-back direction, so that the plate body can switch between an expanded state and a folded state relative to the frame body through the insertion channel;

[0035] Wherein, the frame includes a first connecting portion, the plate includes a second connecting portion, and the second connecting portion includes the moving member;

[0036] 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.

[0037] In this design, a frame or support member is mounted on a component; when the panel is in the expanded state, the support member is inserted into the panel's insertion channel along the front-to-back direction. The support member is inserted into the interior of the panel to limit the panel's vertical movement or rotation, supporting the panel and limiting its position in the vertical direction. At the same time, the contact area between the support member and the panel is large, increasing the panel's load-bearing capacity and improving its bearing capacity. Since the support member can limit the panel's downward rotation after insertion, limiting the panel's rotation relative to the frame, the panel's bearing capacity is increased, and the panel's deformation under load is minimized or prevented. Multiple support members are inserted into the panel's insertion channels along the front-to-back direction, increasing the support area for the panel and improving its bearing capacity.

[0062] In the prior art, there are technical problems as described in the background art.

[0063] To solve the above technical problems, please refer to Figures 1 to 17 , this embodiment provides a limiting assembly 10, including a moving member 1, a locking member 2 and an unlocking mechanism 3, at least a portion of the moving member 1 can form a motion path by sliding and / or rotating, and the motion path includes a locked position; the locking member 2 includes a first locking portion 21, a first elastic member 22 and a first limiting portion 23, and the first locking portion 21 can enter the motion path through the first elastic member 22; a portion of the unlocking mechanism 3 is arranged in the motion path, and the unlocking mechanism 3 includes a third limiting portion 311, and the third limiting portion 311 cooperates with the first limiting portion 23; wherein, when at least a portion of the moving member 1 slides and / or rotates to the locked position along the predetermined direction X, the first locking portion 21 The first locking portion 21 enters the motion path through the first elastic member 22, and the first locking portion 21 abuts against at least a portion of the moving member 1 to limit the moving member 1 from sliding and / or rotating in a direction opposite to the predetermined direction X; when an external force drives the first locking portion 21 to leave the motion path, the first limiting portion 23 cooperates and abuts with the third limiting portion 311 to maintain the first locking portion 21 away from the motion path, and at least a portion of the moving member 1 can slide and / or rotate in a direction opposite to the predetermined direction X, and at least a portion of the moving member 1 can abut against the unlocking mechanism 3 to drive the third limiting portion 311 to separate from the first limiting portion 23, so that the first locking portion 21 enters the motion path through the first elastic member 22.

[0064] The above-mentioned limiting assembly 10 is applied between the plate 30, the frame 20 and the component 40, wherein the frame 20 is fastened to the component 40 by means of fasteners (expansion bolts), gluing, or riveting, and the plate 30 is folded or unfolded relative to the frame 20 by the limiting assembly 10. The plate 30 of this embodiment can be a flat plate or an arc-shaped plate, and the material of the plate 30 can be wood, iron, plastic, or synthetic material; the frame 20 can be a metal frame or a frame made of other hard materials, and the number of the frames 20 can be one or more, and the plate 30 can slide and / or rotate relative to the frame 20; the component 40 can be a wall, a furniture product, or a load-bearing body in a home or office.

[0065] When above-mentioned position limiting assembly 10 is used, moving member 1 is located on plate body 30 or moving member 1 and plate body 30 are an integrally formed structure, locking member 2 can be located on frame body 20 or component 40, and unlocking mechanism 3 can be located on frame body 20 or component 40. Plate body 30 slides and / or rotates relative to frame body 20 by moving member 1, so that plate body 30 can switch between expanded state and folded state. Wherein, the predetermined direction X of above-mentioned moving member 1 is the direction that plate body 30 switches to expanded state from folded state, and the opposite direction of the predetermined direction X of above-mentioned moving member 1 is the direction that plate body 30 switches to folded state from expanded state. When plate body 30 switches to expanded state, moving member 1 moves to locking position, and the first locking portion 21 of locking member 2 automatically enters motion path and abuts to moving member 1 by first elastic member 22, limits plate body 30 to slide and / or rotate towards folded state, thereby realizes the locking effect to plate body 30, so that the plate body 30 under expanded state is safe and reliable. When the plate body 30 needs to be switched from the expanded state to the folded state, the user drives the first locking part 21 out of the movement path by manual or other external force, and adjusts the locking member 2 to the preset position, and the third limiting part 311 of the unlocking mechanism 3 cooperates with the first limiting part 23 of the locking member 2 to abut against each other to maintain the first locking part 21 out of the movement path and separated from the moving member 1. At this time, the user can release the hand that controls the first locking part 21 (or locking member 2), which makes it easier for the user to pull or drive the plate body 30 to slide and / or rotate toward the folded state, so that the unlocking and pulling of the plate body 30 do not need to be performed simultaneously, and the operation is more convenient and easy. And when the plate body 30 slides and / or rotates toward the folded state, at least a portion of the movable member 1 can abut against the unlocking mechanism 3 to control the third limiting portion 311 to separate from the first limiting portion 23, thereby releasing the locking effect of the first locking portion 21, so that the first locking portion 21 enters the motion path under the drive of the first elastic member 22, so that when the plate body 30 switches to the expanded state again, the first locking portion 21 can automatically lock the movable member 1, without the need to readjust the position of the first locking portion 21, reducing the number of adjustments to the first locking portion 21, thereby improving the convenience and intelligence of operation and enhancing the user experience. In addition, the movable member 1 can also be arranged on the frame 20 or the component 40, and the locking member 2 and the unlocking structure 3 are arranged on the plate body 30, which can also achieve the locking and unlocking effect of the above-mentioned plate body 30 in the expanded state, and will not be described in detail here.

[0066] The first elastic member 22 may be a spring or an elastomer made of an elastic material, and the first elastic member 22 is capable of elastic deformation under external force. The first locking portion 21 is directly connected to or abuts the first elastic member 22, so that the first elastic member 22 can drive the first locking portion 21 to move, or the first locking portion 21 can drive the first elastic member 22 to compress or stretch. One of the first limiting portion 23 and the third limiting portion 311 is a groove or notch, and the other is a protrusion or convex portion. The first limiting portion 23 and the third limiting portion 311 are abutted by a concave-convex fit, thereby restricting the first locking portion 21 from entering the motion path. In some specific embodiments, the first limiting portion 23 is a groove structure formed on the first locking portion 21, and the third limiting portion 311 is a protrusion structure. When the first locking portion 21 leaves the motion path and moves to a preset position, the third limiting portion 311 inserts into the first limiting portion 23 to abut, thereby restricting the first locking portion 21 from entering the motion path through the concave-convex fit.

[0067] In some embodiments, a first guide surface 211 is formed on the first locking portion 21 of the present embodiment, and the first guide surface 211 can be an inclined plane or an inclined arc surface, etc.; when the moving member 1 slides and / or rotates to the locked position along the predetermined direction X, at least a portion of the moving member 1 can act on the first guide surface 211, driving the first locking portion 21 to leave the motion path so that the moving member 1 slides and / or rotates to the locked position. The first locking portion 21 is a triangular or conical structure, the first guide surface 211 can be a plane or an arc surface, and the first guide surface 211 gradually tilts upward from the predetermined direction X of the moving member 1, and the side of the first locking portion 21 facing away from the first guide surface 211 can be a vertical surface or a perpendicular surface. When the moving member 1 abuts against the first guide surface 211, the moving member 1 can drive the first locking portion 21 to gradually leave the movement path and compress or stretch the first elastic member 22. When the moving member 1 passes through the first locking portion 21 and moves to the locking position, the first elastic member 22 then returns to its original state and drives the first locking portion 21 to enter the movement path. The side of the first locking portion 21 facing away from the first guide surface 211 abuts against at least a portion of the moving member 1, limiting the moving member 1 from sliding and / or rotating in a direction opposite to the predetermined direction X.

[0068] In some embodiments, the unlocking mechanism 3 of this embodiment further includes a second elastic member 32. When an external force drives the first locking portion 21 to leave the motion path, the second elastic member 32 drives the third limiting portion 311 to slide and / or rotate, causing the third limiting portion 311 to engage with the first limiting portion 23 to maintain the first locking portion 21 out of the motion path. The second elastic member 32 may be a spring or an elastomer made of an elastic material. When the first locking portion 21 enters the motion path, the second elastic member 32 is deformed, exerting a pushing or pulling force on the third limiting portion 311 to maintain the third limiting portion 311 in contact with the surface of the first locking portion 21. When the first limiting portion 23 moves to the position of the third limiting portion 311, the first locking portion 21 leaves the motion path. The second elastic member 32 drives the third limiting portion 311 to slide and / or rotate, and then engages with the first limiting portion 23 to maintain the first locking portion 21 out of the motion path. In other embodiments, the unlocking mechanism 3 does not include the second elastic member 32. When the first limiting portion 23 moves to the position of the third limiting portion 311, the third limiting portion 311 can be driven to slide and / or rotate by external force (for example, manually) so that the third limiting portion 311 cooperates and abuts against the first limiting portion 23.

[0069] In the present invention, the moving member 1 driving the third limiting portion 311 to slide and / or rotate may include the moving member 1 directly or indirectly acting on the third limiting portion 311 to drive the third limiting portion 311 to move.

[0070] As some embodiments in which the moving member 1 directly drives the third limiting portion 311 to move, for example Figures 1 to 8As shown, the unlocking mechanism 3 includes a first limiting member 31, a portion of the first limiting member 31 forms a third limiting portion 311, and a portion of the first limiting member 31 is located in the motion path to form a first unlocking portion 312. It can be understood that one end of the first limiting member 31 forms the third limiting portion 311, and the other end of the first limiting member 31 forms the first unlocking portion 312; when the moving member 1 slides and / or rotates to the position of the first unlocking portion 312 in the opposite direction to the predetermined direction X, at least a portion of the moving member 1 drives the first unlocking portion 312 to move, driving the third limiting portion 311 to separate from the first limiting portion 23, so that the first locking portion 21 enters the motion path through the first elastic member 22. When the moving moving member 1 abuts against the first unlocking portion 312, it drives the first unlocking portion 312 to move, thereby driving the third limiting portion 311 to move so that the third limiting portion 311 and the first limiting portion 23 are separated from each other. The first limiting member 31 is, for example, L-shaped as a whole. The end of the horizontal section of the first limiting member 31 can be the third limiting portion 311, and the vertical section of the first limiting member 31 can be the first unlocking portion 312. When the movable member 1 moves in the horizontal direction and drives the first unlocking portion 312 to move horizontally, it drives the third limiting portion 311 to move horizontally, thereby separating the third limiting portion 311 from the first limiting portion 23.

[0071] As some implementation methods of the technical solution of the movable member 1 indirectly driving the third limiting portion 311 to move, Figures 9 to 16As shown, the unlocking mechanism 3 includes a first limiting member 31 and an unlocking member 33, one end of the first limiting member 31 forms a third limiting portion 311, and the other end of the first limiting member 31 forms a second operating portion 313; the unlocking member 33 includes a third operating portion 331 and a second unlocking portion 332, the third operating portion 331 is arranged in the movement path, and the second unlocking portion 332 cooperates with the second operating portion 313; wherein, when the moving member 1 slides and / or rotates in the opposite direction to the predetermined direction X to the position of the second unlocking portion 332, at least a part of the moving member 1 drives the second unlocking portion 332 to move, thereby driving the second unlocking portion 332 to drive the second operating portion 313 to move, and the second operating portion 313 drives the third limiting portion 311 to separate from the first limiting portion 23, so that the first locking portion 21 enters the movement path through the first elastic member 22. When the cam 331 is in the unlocking state, the second unlocking portion 332 is engaged with the first locking portion 313 and the second locking portion 311 is engaged with the first locking portion 313.

[0072] Furthermore, in some embodiments, in order to enable the moving member 1 to drive the third operating part 331 to move, the third operating part 331 includes a fourth guide surface 331a, and the fourth guide surface 331a can be an inclined plane or an inclined arc surface, etc.; when the moving member 1 slides and / or rotates in the opposite direction of the predetermined direction X, at least a portion of the moving member 1 can act on the fourth guide surface 331a to drive the third operating part 331 to move, thereby driving the second unlocking part 332 to drive the second operating part 313 to move, and the second operating part 313 drives the third limiting part 311 to separate from the first limiting part 23, so that the first locking part 21 enters the movement path through the first elastic member 22.

[0073] Furthermore, in some embodiments, in order to enable the unlocking member 33 (or the second unlocking portion 332) moving in the vertical direction to drive the second operating portion 313 to move in the horizontal direction, the second operating portion 313 includes a second guide surface 313a, and the second guide surface 313a can be an inclined plane or an inclined arc surface, etc. The second unlocking portion 332 can act on the second guide surface 313a to drive the third limiting portion 311 to move, so that the third limiting portion 311 and the first limiting portion 23 are separated, thereby allowing the first locking portion 21 to enter the movement path through the first elastic member 22.

[0074] Furthermore, in some embodiments, to enable the unlocking member 33 (or the second unlocking portion 332) moving in the vertical direction to drive the second operating portion 313 to move in the horizontal direction, the second unlocking portion 332 includes a third guide surface 332a, which can be an inclined plane or an inclined arc surface. The third guide surface 332a can abut against the second operating portion 313 to drive the third limiting portion 311 to move, thereby separating the third limiting portion 311 from the first limiting portion 23, thereby allowing the first locking portion 21 to enter the motion path through the first elastic member 22. The third guide surface 332a and the second operating portion 313 cooperate and abut, and the vertical movement of the unlocking member 33 is converted into horizontal movement of the first limiting member 31, thereby separating the third limiting portion 311 from the first limiting portion 23.

[0075] When the second operating portion 313 includes a second guide surface 313a and the second unlocking portion 332 includes a third guide surface 332a, the second guide surface 313a and the third guide surface 332a fit together, so that the movable unlocking member 33 drives the first limiting member 31 to move after the third guide surface 332a cooperates with the second guide surface 313a, so that the third limiting portion 331 no longer abuts the first limiting portion 23.

[0076] In some embodiments, the unlocking mechanism 3 further includes a third elastic member 34, which is connected to the unlocking member 33; when at least a portion of the moving member 1 passes through the third operating portion 331, the third elastic member 34 drives the third operating portion 331 to enter the motion path. The third elastic member 34 can be a spring or an elastomer made of elastic material. When the moving member 1 passes through the third operating portion 331 along a predetermined direction X or in the opposite direction of the predetermined direction X, the moving member 1 drives the third operating portion 331 to leave the motion path and compresses or stretches the third elastic member 34. After the moving member 1 passes through the third operating portion 331, the third elastic member 34 returns to its original state and drives the third operating portion 331 to enter the motion path. This eliminates the need for or reduces manual reset of the third operating portion 331, thereby improving the intelligence of the unlocking mechanism 3.

[0077] In some embodiments, the locking member 2 further includes a first operating portion 24, which is used to apply an external force to drive the first locking portion 21 out of the motion path. The first operating portion 24 is connected to or integrally formed with the first locking portion 21. The first operating portion 24 can be, for example, a bolt or a column. At least a portion of the first operating portion 24 extends outside the plate 30, the frame 20, or the component 40, and serves as a point of force application to drive the first locking portion 21 out of the motion path.

[0078] In some embodiments, the first operating portion 24 includes an operating handle 241. When an external force is applied to the operating handle 241, the first locking portion 21 is driven out of the motion path. The operating handle 241 is a portion of the first operating portion 24. The operating handle 241 extends outside the plate 30, the frame 20, or the member 40. The size and shape of the operating handle 241 can be adapted to the hand, making it convenient for the user to apply the operating handle 241 to actuate the first locking portion 21.

[0080] In some embodiments, the movable member 1 can be a rotating shaft or a sliding shaft or a folding mechanism of the prior art, and the movable member 1 is mounted on the plate 30 or the movable member 1 and the plate 30 are formed into an integral structure by a casting or injection molding process. The frame 20 is formed with a sliding groove or a sliding track for sliding and / or rotating with the movable member 1, and at least a portion of the movable member 1 is arranged in the sliding groove or the sliding track of the frame 20, or the movable member 1 can rotate relative to the frame 20, so that the plate 30 slides and / or rotates relative to the frame 20 through the movable member 1, thereby realizing the expansion or folding of the plate 30 relative to the frame 20. When the plate 30 is in the expanded state, the plate 30 is in a substantially horizontal state, and the plate 30 is parallel or nearly parallel to the ground, for example, the angle between the plate 30 and the ground is -10° to 10°; when the plate 30 is in the expanded state, the plate 30 is in a substantially vertical state, and the plate 30 is relatively vertical or nearly vertical to the ground, for example, the angle between the plate 30 and the ground is 80° to 100°.

[0081] In some embodiments, for example Figures 1-17 As shown, the frame 20 includes at least one support member 201, one end of the support member 201 is used to be installed on the component 40, and the other end of the support member 201 protrudes from the component 40; or, the frame 20 is used to be installed on the component 40, and the frame 20 is provided with at least one support member 201, at least a part of the support member 201 protrudes from the component 40; the front side of the plate 30 is formed with a plug-in channel 301 extending in the front-to-back direction, so that the plate 30 can switch between the expanded state and the retracted state relative to the frame 20 through the plug-in channel 301; wherein, the frame 20 includes a first The connecting portion 202 includes a second connecting portion 302, and the second connecting portion 302 includes a movable member 1. When the plate body 30 switches to the expanded state, at least a portion of the support member 201 is inserted into the insertion channel 301, and the plate body 30 is in a substantially horizontal state. When the plate body 30 switches from the expanded state to the folded state, the support member 201 is removed from the insertion channel 301, and the first connecting portion 202 and the second connecting portion 302 are connected and cooperated with each other to keep the plate body 30 connected to the frame 20, and the plate body 30 can be rotated downward to be in a substantially vertical state or even in a folded state. Preferably, the second connecting portion 302 can serve as the movable member 1.

[0082] It should be noted that the frame 20 may include a support member 201, one end of which may be removably or non-removably mounted on the component 40, such as by fasteners, adhesive, expansion bolts, or other connectors, or a portion of the support member 201 may be inserted into the component 40 and then secured by expansion or interference fit, while the other end of the support member 201 protrudes from the component 40. Furthermore, the support member 201 may also be a component or part of the frame 20, which may be removably or non-removably mounted on the component 40, such as by hooks, fasteners, bolts, or other connectors, while the support member 201 protrudes entirely or partially from the component 40. The first connecting portion 202 may be a portion of the frame 20, or a component or structure mounted on the frame 20; the second connecting portion 302 may be a portion of the plate 30, or a component or structure mounted on the plate 30.

[0083] For example Figure 1 As shown, 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 20, 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 20, and the front and back direction of this embodiment 1 may refer to the direction from one end of the support 201 close to the component 40 to the end of the support 201 away from the component 40 (or when the plate body 30 is in a basically horizontal state, the direction from one end of the plate body 30 close to the component 40 to the end of the plate body 30 away from the component 40).

[0084] When the panel 30 is in the deployed state, the support member 201 is inserted into the insertion channel 301 of the panel 30 in the front-to-back direction. The support member 201 is inserted into the panel 30 to restrict vertical movement or rotation of the panel 30, providing support and vertical position control for the panel 30. Furthermore, the contact area between the support member 201 and the panel 30 is large, increasing the load-bearing capacity of the panel 30 and enhancing its load-bearing capacity. Because the support member 201 is inserted into the panel 30 in the front-to-back direction, the axis of downward rotation of the panel 30 relative to the frame 20 is in the left-to-right direction. Therefore, the support member 201, once inserted into the panel 30, restricts downward rotation of the panel 30 and prevents rotation of the panel 30 relative to the frame 20, thereby increasing its load-bearing capacity. By providing multiple support members 201 or increasing the surface area of the support members 201, the support area for the panel 30 can be increased, thereby improving its load-bearing capacity and reducing deformation of the panel 30.
