Description

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 the utilization rate of indoor space, some indoor tables or chairs have a folding function. For example, the "Fixed Support Mechanism, Folding Mechanism and Folding Table" disclosed in Chinese patent application number CN201410128026.4 easily forms a scissor-like structure between the wall-fixed frame and the desktop support frame during the folding process, and / or, the wall-fixed frame / desktop support frame / sliding support rod easily forms a scissor-like structure during the folding process, which can easily cause damage to people's hands.

[0003] Another example is the "A Wall-Mounted Foldable Workbench" disclosed in Chinese patent application number CN202221254779.6. During the unfolding and folding process, it is necessary to operate the inner rod body or the first connecting rod or the second connecting rod. The operation is relatively complicated and the stability is relatively poor. During use, it is easy to accidentally touch the inner rod body or the first connecting rod and cause it to fall over.

[0004] Another example is the "A High-Strength Wall-Mounted Foldable Table" disclosed in Chinese patent application number CN201920864556.3, which also has the problem of needing to operate 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 rotate the tabletop panel to place it in an expanded or folded state. When the tabletop panel is in the expanded state, it can be used to place objects, and when it is in the folded state, it can save space. However, in the expanded state, existing folding tables use a support mechanism to support the bottom of the tabletop panel. The support force is weak, resulting in a weak load-bearing capacity of the tabletop panel. When the tabletop panel carries too many objects or the user applies strong force to the tabletop panel, the folding table is easily damaged, posing a danger to use. Moreover, when the tabletop panel is expanded, the bottom support structure is exposed under the tabletop, which fails to meet people's demand for simple and beautiful furniture.

[0006] To this end, the Chinese patent application number CN202210425146.5, entitled "A Table Assembly and Seat for a Vehicle," adds a longitudinal guide rail so that the table body can be supported on the longitudinal guide rail when in the unfolded state. Compared with the prior art solution that is only supported on the rotating shaft, it has higher stability. The table body is locked or unlocked by the cooperation of a locking member and a groove on the table body. When an external force drives the table body to slide toward the vertical guide rail, the locking member disengages from the groove to achieve unlocking. However, the user may easily pull the table body due to misoperation to put the table body in the folded state, causing objects on the table body to tip over or fall. Therefore, the locking stability of the table body is poor, and there is a certain risk of use. Summary of the Invention

[0007] In order to solve the technical problems of the above-mentioned prior art folding tables having weak load-bearing capacity and poor locking stability of the table top, the present invention provides a turning device comprising:

[0008] A frame, wherein the frame includes at least one support member, one end of the support member is used to be mounted on the component, the other end of the support member protrudes from the component and includes an upper support plate and a lower support plate, the upper support plate and the lower support plate are relatively spaced apart in the vertical direction to form a plug-in channel; or, the frame is used to be mounted on the component, the frame is provided with at least one support member, at least a portion of the support member protrudes from the component and includes an upper support plate and a lower support plate, the upper support plate and the lower support plate are relatively spaced apart in the vertical direction to form a plug-in channel;

[0009] and a second connecting portion, wherein the first connecting portion and the second connecting portion are connected to each other to keep the plate connected to the frame, and the plate body is rotated downward so that the plate body is in a basically vertical state and even in the folded state.

[0010] and a limit assembly, which can switch between a locked state and an unlocked state; when the plate body is in the expanded state, the limit assembly can switch to the locked state so that the plate body cannot switch to the folded state; and, the limit assembly can switch to the unlocked state so that the plate body can be moved out of the insertion channel and rotated downward relative to the frame body to switch to the folded state.

[0011] Compared with the prior art, the flipping device of the present invention has the following advantages:

[0012] When the board is in the unfolded state, the upper side of the board abuts against the upper support plate of the frame, and the lower side of the board abuts against the lower support plate of the frame. The upper and lower support plates limit the movement of the board in the up and down directions, play a supporting role for the board and a limiting role in the up and down directions, thereby improving the load-bearing capacity of the board and better making the board deform less or not deform under load, so that the board can carry more objects or withstand a larger force applied to the board by the user, and even the user can sit or stand on the board, which greatly improves the load-bearing capacity of the board and reduces the deformation of the board.

[0013] The limiter assembly controls the state of the panel. When the panel is extended, the limiter assembly is locked, restricting the panel from switching to the retracted state, ensuring stability and safety in the extended state. When the limiter assembly is unlocked, an external force can drive the panel from the extended state to the retracted state, saving space. The limiter assembly cooperates with the frame or panel to maintain the stability of the panel in the extended state and switch to the retracted state, providing high reliability and safety.

[0014] In some embodiments, the limiting assembly includes a locking member, and the locking member can be provided on the frame, the plate, or the component;

[0015] When the locking member is provided on the frame or the component, the limiting assembly further comprises a first locking space provided on the plate body, and when the plate body switches from the folded state to the expanded state, the locking member can enter the first locking space, and at least a portion of the locking member can abut against the plate body, so that the limiting assembly enters the locked state;

[0016] When the locking member is provided on the plate body, the limiting assembly further includes a second locking space provided on the frame body or the component. When the plate body switches from the folded state to the expanded state, the locking member can enter the second locking space, and at least a portion of the locking member can abut against the frame body or the component to switch the limiting assembly to the locked state.

[0017] Under this design, the locking member cooperates with the first locking space or the second locking space to form a mutually restrictive relationship between the plate and the frame or the component, thereby achieving the effect of locking the plate, thereby preventing or reducing the risk of the plate switching to the folded state in the event of user error.

[0018] In some embodiments, the locking member includes a first locking portion, which enters the first locking space or the second locking space by sliding or rotating. The first locking portion can enter and at least partially exit the first locking space or the second locking space, thereby switching the limit assembly between a locked state and an unlocked state.

[0019] In some embodiments, the locking member further includes a first operating portion, the first operating portion being used for an external force to drive the first locking portion into the first locking space or the second locking space, thereby causing the limiting assembly to enter the locked state; or, the first operating portion being used for an external force to drive the first locking portion out of the first locking space or the second locking space, thereby causing the limiting assembly to enter the unlocked state. The first operating portion is used to provide an external force application point, and the external force acts on the first operating portion to drive the first locking portion to displace (stretch or press or move or rotate or other movements), so that the first locking portion enters or at least partially exits the first locking space or the second locking space, thereby adjusting the working state of the limiting assembly.

[0020] In some embodiments, the locking member further includes a first elastic member, which can drive the first locking portion to enter and remain in the first locking space or the second locking space, so that the limiting assembly is in the locked state; when the first locking portion enters the first locking space or the second locking space, the locking member is in the first state; when the first locking portion leaves the first locking space or the second locking space, the locking member is in the second state. The first elastic member can stably maintain the first locking portion in the first locking space or the second locking space, and even if the plate body is hit by a strong external force and causes the first locking portion to temporarily leave the first locking space or the second locking space, the first elastic member can also give the first locking portion an elastic force to make the first locking portion re-enter the first locking space or the second locking space, thereby preventing the plate body from being folded due to misoperation during use.

[0021] In some embodiments, the locking member further includes a first limiting portion, which is used to limit the locking member from switching from the second state to the first state, thereby maintaining the limiting assembly in the unlocked state. With this design, the user does not need to simultaneously unlock the limiting assembly and retract the plate. When the length of the plate is relatively large, the limiting assembly can be controlled to remain unlocked using the first limiting portion, and then the plate can be driven to the retracted state using both hands, thereby improving the convenience of driving the plate and reducing the difficulty of retracting the plate.

[0022] In some embodiments, the limiting assembly further includes a first limiting member, the first limiting member includes a third limiting portion, the third limiting portion can abut against the first limiting portion to maintain the limiting assembly in the unlocked state, and when the third limiting portion abuts against the first limiting portion, the locking member is in the seventh state. Under this design, the position of the first limiting member or the locking member can be adjusted so that the third limiting portion cooperates with the first limiting portion, thereby generating a mutual restriction effect between the first limiting member and the locking member, so that the locking member is maintained in the unlocked state.

[0023] In some embodiments, the limiting assembly further comprises a second elastic member. When the locking member is in the seventh state, the second elastic member can drive the third limiting portion into the third state so that the third limiting portion abuts the first limiting portion, thereby maintaining the limiting assembly in the unlocked state. This design can maintain a stable abutment between the third limiting portion and the first limiting portion, thereby stably maintaining the limiting assembly in the unlocked state, ensuring that the user can smoothly fold the panel.

[0024] In some embodiments, the first limiting member includes a second operating portion, and the second operating portion is used to allow an external force to drive the third limiting portion to displace so that the third limiting portion and the first limiting portion no longer abut each other, thereby allowing the locking member to switch to the first state. The second operating portion is used to provide an external force application point, and the external force acts on the second operating portion to drive the third limiting portion to displace (stretch, press, move, rotate or other movements) so that the third limiting portion and the first limiting portion no longer abut each other, thereby releasing the matching relationship between the third limiting portion and the first limiting portion, thereby placing the locking member in the first state, that is, placing the limiting assembly in the locked state; or, when the locking member is in the first state, the limiting assembly may not be in the locked state.

[0025] In some embodiments, the limit assembly further includes an unlocking member, and the unlocking member includes a fifth state and a sixth state; when the unlocking member is in the fifth state, the third limit portion is in the third state; when the unlocking member is transformed from the fifth state to the sixth state under the action of an external force, the unlocking member can act on the second operating part to drive the third limit portion to displace, so that the third limit portion and the first limit portion no longer abut each other, so that the locking member can switch to the first state. The addition of the unlocking member makes the transmission structure of the limit assembly more sophisticated, and the unlocking member is used to control the connection relationship between the third limit portion and the first limit portion, thereby adjusting the state of the locking member. This process does not require manual control or reduces manual control, and is intelligent and convenient.

[0026] In some embodiments, the unlocking member includes an unlocking portion and a third operating portion, wherein the unlocking portion is configured to interact with the second operating portion, and the third operating portion is configured to be driven by an external force. The third operating portion is configured to provide a point of application for an external force, and the external force acts on the third operating portion to cause the unlocking portion to displace (e.g., in an up-down direction or a forward-backward direction), thereby causing the second operating portion to displace, and driving the third limiting portion to displace so that the third limiting portion and the first limiting portion no longer abut each other.

[0027] In some embodiments, the unlocking member also includes a third elastic member, which is used to put the unlocking member in the fifth state. In this way, the unlocking member can avoid or reduce the excess force exerted by the unlocking member on the first limiting member, ensuring that the second elastic member can drive the first limiting member to move to the third limiting portion and cooperate with the first limiting portion.

[0028] In some embodiments, the first operating portion includes a first guide surface, and the plate or the frame can act on the first guide surface to place the locking member in the second state.

[0029] The direction in which the plate body is inserted into the insertion channel is set as the expansion direction, and the direction in which the plate body is removed from the insertion channel is set as the folding direction;

[0030] When the plate body translates along the insertion channel toward the expansion direction, the plate body or the frame body can act on the first guide surface and switch the locking member from the first state to the second state;

[0031] When the plate body continues to translate in the unfolding direction, the plate body or the frame body passes over the first locking portion, and a portion of the plate body or a portion of the frame body is located in front of the first locking space, so that the locking member switches from the second state to the first state;

[0032] When the plate body translates toward the folding direction, the first locking portion can block at least a portion of the plate body or at least a portion of the frame body, so that the plate body cannot be switched to the folded state.

[0033] With this design, the user does not need to actively control the movement of the locking member, which simplifies the operation steps and improves the user experience.

[0034] In some embodiments, the limiter assembly further includes a second limiter portion that can abut against the first limiter portion to maintain the limiter assembly in the unlocked state. In this design, the position of the locking member can be adjusted so that the second limiter portion cooperates with the first limiter portion, thereby creating a mutual restraint effect between the second limiter portion and the locking member, thereby maintaining the locking member in the unlocked state.

[0035] In some embodiments, when the first limiting portion is provided on the plate, the second limiting portion is provided on the plate; when the first limiting portion is provided on the frame or the component, the second limiting portion is provided on the frame or the component.

[0036] In some embodiments, the first operating part can drive the first limiting part to rotate so that the second limiting part and the first limiting part are in abutment with each other, thereby limiting the movement of the first limiting part, thereby limiting the locking member from switching from the second state to the first state, so that the limiting assembly is in an unlocked state. This design structure is simple, not prone to failure, and is also relatively convenient to operate.

[0037] In some embodiments, the first operating portion includes an operating handle. When an external force acts on the operating handle to drive the locking member to move from the first state to the second state and reach the seventh state, the second elastic member can drive the third limiting portion to enter the third state so that the third limiting portion and the first limiting portion abut against each other, thereby maintaining the limiting assembly in the unlocked state. 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.

[0038] In some embodiments, the first operating portion includes a first guide surface, and the frame, the member, or the plate can act on the first guide surface to place the locking element in the second state;

[0041] When the plate body continues to translate in the unfolding direction, the plate body, the frame body, or the component passes over the first locking portion and the frame body or the component is located in front of the first locking space, or the plate body is located in front of the second locking space, so that the locking member switches from the second state to the first state;

[0042] When the plate body is translated from the locked state to the folded direction, the first locking portion is capable of blocking at least a portion of the plate body, at least a portion of the frame body, or at least a portion of the component, so that the plate body cannot be switched to the folded state;

[0043] The first operating portion includes an operating handle, and when an external force acts on the operating handle to drive the locking member to move from the first state to the second state and reach the seventh state, the second elastic member can drive the third limiting portion to enter the third state so that the third limiting portion abuts against the first limiting portion, thereby maintaining the limiting assembly in the unlocked state;

[0044] When the plate body is translated along the insertion channel toward the folding direction, 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 can act on the second operating portion so that the third limiting portion and the first limiting portion no longer abut against each other, thereby enabling the locking member to switch to the first state.

[0045] With this design, the user does not need to actively control the movement of the locking member, which simplifies the operation steps and improves the user experience.

[0046] In some embodiments, the direction in which the plate is inserted into the insertion channel is set as the expansion direction, and the direction in which the plate is removed from the insertion channel is set as the folding direction; when the plate is translated toward the folding direction, the plate, the frame, or the component can act on the unlocking member, causing the unlocking member to change from the fifth state to the sixth state. At the same time, the unlocking member acts on the second operating portion so that the third limiting portion and the first limiting portion no longer abut each other, thereby enabling the locking member to switch to the first state. With this design, there is no need for the user to actively control the movement of the first limiting member to switch the state of the locking member, simplifying the operating steps and improving the user experience.

[0047] In some embodiments, the third operating portion includes a fourth guide surface; the direction in which the plate is inserted into the insertion channel is set as the expansion direction, and the direction in which the plate is removed from the insertion channel is set as the folding direction; when the plate is translated toward the folding direction, at least a portion of the plate, at least a portion of the frame, or at least a portion of the component can act on the fourth guide surface, and simultaneously, the unlocking member is transformed from the fifth state to the sixth state, and the unlocking portion acts on the second operating portion so that the third limiting portion and the first limiting portion no longer abut each other, thereby enabling the locking member to be in the first state. The fourth guide surface can be an inclined plane or an inclined arc surface, and when at least a portion of the plate, at least a portion of the frame, 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 portion to move, so that the locking member is restored to the first state under the action of the first elastic member.

[0048] In some embodiments, the second operating portion includes a second guide surface, and the 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 be in the first state; 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 be in the first state.

[0083] In some embodiments, when the plate body translates along the insertion channel toward the retracted direction, at least a portion of the first connecting portion or at least a portion of the second connecting portion can act on the unlocking member, causing the unlocking member to change from the fifth state to the sixth state. Simultaneously, the unlocking member acts on the second operating portion so that the third limiting portion and the first limiting portion no longer abut each other, thereby enabling the locking member to switch to the first state. With this design, there is no need for the user to actively control the movement of the first limiting portion to switch the state of the locking member, simplifying the operation steps and improving the user experience.

[0084] In some embodiments, the first connecting portion includes a first slot extending in a front-to-rear direction, the first matching portion is provided at a rear end of the first slot, and at least a portion of the second connecting portion is movably provided in the first slot, and when at least a portion of the second connecting portion moves to the rear end of the first slot and abuts against the first matching portion, the first matching portion and at least a portion of the second connecting portion are connected and enable the plate body to rotate downward so that the plate body is in a substantially vertical state or even a folded state; or,

[0085] The second connecting portion includes a second slot extending in a front-to-back direction, the second matching portion is provided at a front end of the second slot, and at least a portion of the first connecting portion is movably provided in the second slot;

[0086] When at least a portion of the first connecting portion moves to the front end of the second slot and abuts against the second matching portion, the second matching portion and at least a portion of the first connecting portion are connected and enable the plate body to rotate downward so that the plate body is in a basically vertical state or even the folded state.

[0087] Under this design, the first connecting portion cooperates with the first groove or the second connecting portion cooperates with the second groove, so that the plate body can move on the frame body while always remaining connected to the frame body. That is, when the plate body switches between the expanded state and the folded state, there is no need to disassemble and assemble the plate body and the frame body, thereby improving the convenience of the operation of expanding and folding the plate body.

[0088] In some embodiments, the frame includes a left frame and a right frame, the left frame and the right frame being spaced apart from each other in the horizontal direction; the frame is provided with two first slots, the two first slots being provided on the left frame and the right frame respectively, and the two first slots being opposed to each other; the second connecting portion is provided on the left and right side surfaces of the plate respectively, and at least a portion of the two second connecting portions is respectively adapted to the two first slots; or the frame is provided with two first connecting portions, the two first connecting portions being provided on the left and right side surfaces of the plate respectively, and the two first connecting portions being opposed to each other; the two second slots being provided on the left and right side surfaces of the plate respectively, and at least a portion of the two first connecting portions is respectively adapted to the two first slots. This design can make assembly between the plate and the frame more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0132] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0135] In the prior art, there are technical problems as described in the background art.

[0136] Example 1

[0137] To solve the above technical problems, please refer to Figures 1 to 39, this embodiment 1 provides a flip device, including a frame 1, a plate 2 and a limit assembly 3, 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, the other end of the support member 11 protrudes from the component 5 and includes an upper support plate 111 and a lower support plate 112, the upper support plate 111 and the lower support plate 112 are relatively spaced apart in the up and down directions to form an insertion channel 12; 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, at least a part of the support member 11 protrudes from the component 5 and includes an upper support plate 111 and a lower support plate 112, the upper support plate 111 and the lower support plate 112 are relatively spaced apart in the up and down directions to form an insertion channel 12; the frame 1 also includes a first connecting portion 13; the plate 2 includes a second connecting portion 21, and the plate 2 can be extended during the unfolding Switch between the open state and the folded state; when the plate body 2 switches to the expanded state, at least a portion of the plate body 2 is inserted into the insertion channel 12, and at least a portion of the upper side of the plate body 2 is horizontal with the upper support; when the plate body 2 switches from the expanded state to the folded state, the plate body 2 moves out of the insertion channel 12, and the first connection part 13 and the second connection part 21 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 and even in the folded state; the limit component 3 can switch between a locked state and an unlocked state; when the plate body 2 is in the expanded state, the limit component 3 can be switched to a locked state so that the plate body 2 cannot be switched to the folded state; and, the limit component 3 can be switched to an unlocked state so that the plate body 2 can be moved out of the insertion channel 12 and rotated downward relative to the frame body 1 to switch to the folded state.

[0138] It should be noted that the plate body 2 of this embodiment 1 can be in the shape of a flat plate or an arc-shaped plate, etc., and the material can be wood, iron, plastic, or synthetic material, etc. The component 5 can be a wall, a 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 installed on the component 5 by fasteners, glue, 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 upper support plate 111 and the lower support plate 112 can be connected by a connector plate, and the upper support plate 111 and the lower support plate 112 can be fixed to the component 5 so that the upper support plate 111 and the lower support plate 112 protrude from the component 5. The upper support plate 111 and the lower support plate 112 can also be separated from each other. The upper support plate 111 and the lower support plate 112 can be relatively parallel or nearly parallel. As Figure 1 、 Figure 4 、 Figure 7 、 Figure 16 、 Figure 24 、 Figure 34As shown, the plate body 2 is in a substantially 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°; Figure 2 、 Figure 11 、 Figure 20 、 Figure 22 、 Figure 36 、 Figure 38 As shown, the board 2 being in a substantially vertical position means that the board 2 is relatively perpendicular or nearly perpendicular to the ground, for example, the angle between the board 2 and the ground is 80° to 100°. The first connecting portion 13 can be part of the frame 1 or a separate component mounted on the frame 1; the second connecting portion 21 can be part of the board 2 or a separate component mounted on the board 2.

[0139] For example Figures 1 to 39 As shown, the up and down direction of the present invention may refer to the direction from top to bottom when the user is facing the frame 1, the left and right direction of the present invention may refer to the direction from left to right when the user is facing the frame 1, and the front and back direction of the present invention 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).

[0140] When the panel 2 is in the unfolded state, the upper side of the panel 2 abuts against the upper support plate 111 of the frame 1, and the lower side of the panel 2 abuts against the lower support plate 112 of the frame 1. The upper support plate 111 and the lower support plate 112 limit the movement of the panel 2 in the up and down directions, supporting the panel 2 and limiting its position in the up and down directions, thereby improving the load-bearing capacity of the panel 2 and better ensuring that the panel 2 has little or no deformation when under load, so that the panel 2 can carry more objects or withstand greater force exerted by the user on the panel 2, and even allow the user to sit or stand on the panel 2, thereby greatly improving the load-bearing capacity of the panel 2 and reducing the deformation of the panel 2. The limit assembly 3 is used to control the state of the panel 2. When the panel 2 is in the unfolded state, the limit assembly 3 is in a locked state, limiting the panel 2 from switching to the folded state through the limit assembly 3, thereby ensuring the stability and safety of the panel 2 in the unfolded state. When the limiter assembly 3 is unlocked, an external force drives the panel 2 to switch from the extended state to the retracted state, saving space. The limiter assembly 3 cooperates with the frame 1 or the panel 2 to stably maintain the panel 2 in the extended state and switch to the retracted state, providing high reliability and safety.

[0141] Among them, an avoidance portion is formed on the upper surface of the front end of the plate body 2 so that when the plate body 2 is in the unfolded state, the upper surface of the plate body 2 and the upper surface of the upper support plate 111 are in the same plane, thereby improving the overall aesthetics of the flip device and preventing objects placed on the plate body 2 from tilting easily.

[0142] In some embodiments, the position-limiting assembly 3 of this embodiment 1 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. This embodiment 1 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 component 5, the limiting assembly 3 also includes a first locking space 32 provided on the plate body 2. When the plate body 2 switches from the folded state to the expanded state, the locking piece 31 can enter the first locking space 32, and 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 component 5, and the locking piece 31 can enter the second locking space. When the plate body 2 switches from the folded state to the expanded state, at least a portion of the locking piece 31 can abut against the frame body 1 or component 5, and is connected with the frame body 1 or component 5 through the locking piece 31, so that the limiting assembly 3 switches to the locked state.

[0143] It should be noted that the first locking space 32 can be formed in a slot structure on the plate body 2, the first locking space 32 can also be a space defined between a portion of the plate body 2 and the second connecting portion 21 (for example, the first connecting portion 13), 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, the second locking space can also be a space defined between a portion of the frame body 1 and the first connecting portion 13, or the second locking space can be the surface of the frame body 1 or the component 5.

[0144] 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 21 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 13 of the frame 1, thereby locking the position limiting assembly 3.

[0145] 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 when the plate body 2 is translated from the folded state to the expanded state, at least a portion of the locking member 31 can enter the first locking space 32, and at least a portion of the locking member 31 can abut against the second connecting portion 21, and is connected to the second connecting portion 21 through the locking member 31, 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 when the plate body 2 is translated from the folded state to the expanded state, at least a portion of the locking member 31 can enter the second locking space, and at least a portion of the locking member 31 can abut against the first connecting portion 13, and is connected to the first connecting portion 13 through the locking member 31, and the limiting assembly 3 enters the locked state.

[0146] The present embodiment 1 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, such as Figures 1 to 39 As shown, 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 the first locking portion 311 enters the first locking space 32, it abuts against the plate 2, or after the first locking portion 311 enters the second locking space, it abuts against the frame 1, so that the limit assembly 3 switches to the locked state. For further information, see Figure 3-10 、 Figures 14-19 The locking member 31 is mounted on the plate 2, the frame 1, or the component 5 in a detachable or position-adjustable manner, such as by threaded connection or sliding connection. When the plate 2 is adjusted to the unfolded 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 in the first locking space 32 or the second locking space, thereby restricting the plate 2 from switching to the folded state. In addition, see Figure 16-Figure 19 The locking member 31 can also lock the plate body 2 after the plate body 2 is switched to the folded state, thereby preventing or reducing the plate body 2 from swinging freely in the folded state.

[0147] In some embodiments, the locking member 31 further includes a first operating portion 312, which is used for 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 for 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 drive the first locking portion 311 to displace (stretch, press, move, rotate, or other movement) so that the first locking portion 311 enters or leaves the first locking space 32 or the second locking space, thereby adjusting the working state of the limiting assembly 3. By an external force (such as a pulling force or a compressive force) acting on the first operating portion 312 and maintaining it, the first locking portion 311 is maintained out of the first locking space 32 or the second locking space, thereby ensuring that the limiting assembly 3 is in an unlocked state.

[0148] In some embodiments, as Figures 11 to 13 、 Figures 20 to 39 As shown, the locking member 31 also includes a first elastic member 313. The first elastic member 313 is capable of forcing the first locking portion 311 into the first locking space 32 or the second locking space, thereby locking the stop assembly 3. 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 force the first locking portion 311 into the first locking space 32 or the second locking space by stretching or compressing, thereby improving actuation convenience. The first elastic member 313 may also be other elastically deformable materials, such as rubber or silicone. When the locking member 31 is in the first state, the first locking portion 311 enters the first locking space 32 or the second locking space. When the locking member 31 is in the second state, the first locking portion 311 leaves the first locking space 32 or the second locking space, or a portion of the first locking portion 311 is still in the first locking space 32 or the second locking space but does not abut against the plate 2 or the frame 1 .

[0149] 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 limiting assembly 3 in the unlocked state. The first limiting portion 314 can be connected to the first operating portion 312, or can be connected to the first locking portion 311. By driving the first limiting portion 314 to move relative to the plate body 2 or the frame body 1 or the component 5, the position of the first limiting portion 314 is adjusted to place the locking member 31 in the first state or the second state, wherein when the first limiting portion 314 is in the preset position, the first limiting portion 314 can cooperate with the plate body 2 or the frame body 1 or 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 limiting 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 body 2 or the frame body 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.

[0150] In some embodiments, the lower support plate 112 is arranged within the vertical projection area of ​​the upper support plate 111 from top to bottom. The area of ​​the upper support plate 111 is larger than the area of ​​the lower support plate 112. When viewed from top to bottom, the lower support plate 112 is located within the projection surface of the upper support plate 111. The user cannot observe the lower support plate 112 from top to bottom, thereby improving the overall aesthetics of the flip device.

[0151] In some embodiments, as Figure 38 、 Figure 39 As shown, the flipping device of this embodiment 1 also 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 mechanism 4 can be installed on the plate body 2 or the frame body 1 or the component 5. When the base of the buffer mechanism 4 is installed on the frame body 1, the telescopic end of the buffer mechanism 4 is connected to the plate body 2, so that when the plate body 2 rotates to a basically vertical state relative to the frame body 1, the buffer mechanism 4 has a buffering effect on the rotating plate body 2, preventing or reducing damage to the plate body 2 caused by excessive rotation due to inertia or collision with the frame body 1 or the component 5.

[0152] Example 2

[0153] The turning device of the present embodiment 2 is similar to the turning device of the above embodiment 1, except that: Figures 22 to 29As shown, the limiting assembly 3 of the flipping device of this embodiment 2 further includes a first limiting member 34, which includes a third limiting portion 341. The third limiting portion 341 can abut against the first limiting portion 314 to maintain the limiting assembly 3 in the unlocked state. When the third limiting portion 341 abuts against the first limiting portion 314, the locking member 31 is in the seventh state. The first limiting portion 314 of the flipping device of this embodiment 2 cooperates with the third limiting portion 341 of the first limiting member 34 to keep the first locking portion 311 away from the first locking space 32 or the second locking space, thereby maintaining the limiting assembly 3 in the unlocked state.

[0154] The first stopper 34 can be provided on the plate 2, the frame 1, or the member 5. When the first stopper 314 is in a preset position, it abuts against the third stopper 341, thereby placing the stopper assembly 3 in the unlocked state. The seventh state is a variant of the second state, during which the locking member 31 is also in the second state. In some embodiments, one of the first stopper 314 and the third stopper 341 is a protruding structure and the other is a recessed structure, and the first stopper 314 and the third stopper 341 abut against each other through a concave-convex fit, thereby placing the stopper assembly 3 in the unlocked state. For example, the first stopper 314 is a recessed structure provided on the locking member 31, or the locking member 31 includes at least two relatively spaced components, with the first stopper 314 being a recessed structure formed by a gap between the two components. In other embodiments, the first stopper 314 and the third stopper 341 are connected by magnetic attraction or a snap-fit ​​mechanism, thereby placing the stopper assembly 3 in the unlocked state.

[0155] In some embodiments, the limiting assembly 3 of this embodiment 2 further includes a second elastic member 35. When the locking member 31 is in the seventh state, the second elastic member 35 can drive the third limiting portion 341 to enter the third state so that the third limiting portion 341 and the first limiting portion 314 abut against each other, thereby maintaining the limiting assembly 3 in the unlocked state. The second elastic member 35 is connected to the locking member 31. The second elastic member 35 can be, for example, a spring member or a tension spring member. The second elastic member 35 can be in a deformation state of tension or compression. When the second elastic member 35 is in the deformation state, the third limiting portion 341 is driven to displace by the elastic potential energy of the second elastic member 35 so that the third limiting portion 341 abuts against the first limiting portion 314, thereby maintaining the limiting assembly 3 in the unlocked state.

[0156] In some embodiments, the first operating portion 312 includes an operating handle 312b, which can be disposed on the outside of the plate body 2 or the frame body 1 or the component 5. When an external force acts on the operating handle 312b to drive the locking member 31 to move from the first state to the second state and reach the seventh state, the second elastic member 35 can drive the third limiting portion 341 to enter the third state so that the third limiting portion 341 and the first limiting portion 314 abut against each other, thereby maintaining the limiting assembly 3 in an unlocked state.

[0157] In some embodiments, the first limiting member 34 includes a second operating portion 342, which is used to allow an external force to drive the third limiting portion 341 to displace so that the third limiting portion 341 and the first limiting portion 314 no longer abut each other, thereby allowing the locking member 31 to switch to the first state. The second operating portion 342 is used to provide an external force application point. The external force acts on the second operating portion 342 to drive the third limiting portion 341 to displace (stretch, press, move, rotate, or other movement) so that the third limiting portion 341 and the first limiting portion 314 no longer abut each other, thereby releasing the mating relationship between the third limiting portion 341 and the first limiting portion 314, thereby placing the locking member 31 in the first state, that is, the limiting assembly 3 is in the locked state.

[0158] The second operating part 342 can be manually operated or other components can be used to act on the second operating part 342 to keep the third limiting part 341 from abutting against the first limiting part 314, so that the locking member 31 is in the first state and the limiting assembly 3 is in the locked state.

[0159] Example 3

[0160] The turning device of the present embodiment 3 is similar to the turning device of the above embodiment 2, except that: Figures 22 to 29 As shown, the limiting assembly 3 of the flip device of this embodiment 3 further includes an unlocking member 36. When the unlocking member 36 acts on the second operating portion 342, the connection between the third limiting portion 341 of the first limiting portion 34 and the first limiting portion 314 is adjusted. Specifically, the unlocking member 36 of this embodiment 3 includes a fifth state and a sixth state. When the unlocking member 36 is in the fifth state, the third limiting portion 341 is in the third state, so that the third limiting portion 341 and the first limiting portion 314 abut against each other, and the locking member 31 can switch to the second state, thereby maintaining the limiting assembly 3 in the unlocked state. When the unlocking member 36 is transformed from the fifth state to the sixth state under the action of an external force, the unlocking member 36 can act on the second operating portion 342 to drive the third limiting portion 341 to displace, so that the third limiting portion 341 and the first limiting portion 314 no longer abut against each other, thereby enabling the locking member 31 to switch to the first state.

[0161] The unlocking member 36 can be switched between the fifth state and the sixth state manually, or by the plate 2 or the frame 1 pushing the unlocking member 36 during the movement of the plate 2 relative to the frame 1, thereby switching the unlocking member 36 from the fifth state to the sixth state.

[0162] In some embodiments, the unlocking member 36 includes an unlocking portion 361 and a third operating portion 362. The unlocking portion 361 is configured to interact with the second operating portion 342, and the third operating portion 362 is configured to be driven by an external force. The third operating portion 362 is configured to provide a point of application for an external force. The external force acts on the third operating portion 362 to cause the unlocking portion 361 to move (e.g., in the up-down direction or the front-back direction), thereby causing the second operating portion 342 to move, driving the third limiting portion 341 to move so that the third limiting portion 341 and the first limiting portion 314 no longer abut each other.

[0163] In some embodiments, the unlocking member 36 further includes a third elastic member 363, which is configured to position the unlocking member 36 in the fifth state. The third elastic member 363 may be, for example, a spring or a tension spring. When the unlocking member 36 is in the sixth state, the third elastic member 363 can drive the unlocking member 36 to switch to the fifth state, positioning the third limiting portion 341 in the third state and causing the third limiting portion 341 to abut against the first limiting portion 314, thereby maintaining the limit assembly 3 in the unlocked state.

[0164] In some embodiments, the direction in which the plate 2 is inserted into the insertion channel 12 is defined as the deployment direction, and the direction in which the plate 2 is removed from the insertion channel 12 is defined as the folding direction. When the plate 2 is translated in the folding direction, the plate 2, the frame 1, or the component 5 can act on the unlocking member 36, causing the unlocking member 36 to change from the fifth state to the sixth state. Simultaneously, the unlocking member 36 acts on the second operating portion 342 to disengage the third limiting portion 341 from abutting against the first limiting portion 314, thereby enabling the locking member 31 to switch to the first state. During the movement of the plate 2 relative to the frame 1, the plate 2, the frame 1, or the component 5 acts on the unlocking member 36 to switch from the fifth state to the sixth state. The third limiting portion 341 of the first limiting member 34 abuts against the first limiting portion 314, maintaining the limiting assembly 3 in the unlocked state.

[0165] In some embodiments, the third operating portion 362 includes a fourth guide surface 362a, which can be an inclined plane or an inclined arc surface. The direction in which the plate 2 is inserted into the insertion channel 12 is defined as the deployment direction, and the direction in which the plate 2 is removed from the insertion channel 12 is defined as the retraction direction. When the plate 2 is translated in the retraction direction, at least a portion of the plate 2, at least a portion of the frame 1, or at least a portion of the component 5 can act on the fourth guide surface 362a, causing the unlocking member 36 to transition from the fifth state to the sixth state. Simultaneously, the unlocking portion 361 acts on the second operating portion 342 to disengage the third limiting portion 341 from abutting against the first limiting portion 314, thereby resetting the locking member 31 to the first state. When a portion of the plate 2, the frame 1, or the component 5 abuts the fourth guide surface 362a, it acts on the third operating portion 362 to drive the unlocking portion 361 to move, thereby causing the second operating portion 342 to also move, thereby disengaging the third limiting portion 341 from abutting against the first limiting portion 314.

[0166] In some embodiments, the second operating portion 342 includes a second guide surface 342a, which can be an inclined plane or an inclined arc surface. The unlocking portion 361 can act on the second guide surface 342a to drive at least a portion of the first limiting member 34 to move, so that the third limiting portion 341 and the first limiting portion 314 no longer abut each other, thereby allowing the first locking portion 311 to be in the first state. The unlocking portion 361 can be moved by manually or by moving the plate 2. The moving unlocking portion 361 acts on the second guide surface 342a, driving the first limiting member 34 to move, so that the third limiting portion 341 and the first limiting portion 314 no longer abut each other.

[0167] In some embodiments, the unlocking portion 361 includes a third guide surface 361a, which can be an inclined plane or an inclined arc surface. The third guide surface 361a can abut against the second operating portion 342 to drive at least a portion of the first limiting member 34 to move, so that the third limiting portion 341 and the first limiting portion 314 no longer abut against each other, thereby placing the first locking portion 311 in the first state. The unlocking portion 361 can be moved by manually or by moving the plate 2. The moving unlocking portion 361, through the third guide surface 361a and the second operating portion 342, drives the first limiting member 34 to move, so that the third limiting portion 341 and the first limiting portion 314 no longer abut against each other.

[0168] When the second operating portion 342 includes a second guide surface 342a and the unlocking portion 361 includes a third guide surface 361a, the second guide surface 342a and the third guide surface 361a fit together, so that the moving unlocking portion 361 drives the first limiting member 34 to move after the third guide surface 361a cooperates with the second guide surface 342a, so that the third limiting portion 341 no longer abuts the first limiting portion 314.

[0169] In some embodiments, when the second operating portion 342 includes a second guide surface 342a and the unlocking portion 361 includes a third guide surface 361a, the third operating portion 362 includes a fourth guide surface 362a; the direction in which the plate body 2 is inserted into the insertion channel 12 is set as the expansion direction, and the direction in which the plate body 2 is moved out of the insertion channel 12 is set as the folding direction; when the plate body 2 is translated toward the folding direction, at least a portion of the plate body 2 or at least a portion of the frame body 1 or at least a portion of the component 5 can act on the fourth guide surface 362a, and at the same time as the unlocking member 36 is changed from the fifth state to the sixth state, the third guide surface 361a acts on the second guide surface 342a so that the third limiting portion 341 and the first limiting portion 314 no longer abut each other, so that the locking member 31 can be in the first state. The unlocking portion 361 is moved by acting on the fourth guide surface 362a of the third operating portion 362 through the moving plate body 2, and the moving unlocking portion 361 drives the first limiting member 34 to move after cooperating with the second guide surface 342a through the third guide surface 361a, so that the third limiting portion 341 and the first limiting portion 314 are no longer in contact.

[0170] Since the frame 1 includes a first connecting portion 13 and the plate body 2 includes a second connecting portion 21, in some embodiments, when the plate body 2 is translated along the insertion channel 12 in the folding direction, at least a portion of the first connecting portion 13 or at least a portion of the second connecting portion 21 can act on the unlocking member 36, and at the same time, the unlocking member 36 is changed from the fifth state to the sixth state, the unlocking member 36 acts on the second operating portion 342 so that the third limiting portion 341 and the first limiting portion 314 no longer abut each other, so that the locking member 31 can switch to the first state.

[0171] It should be noted that the fourth guide surface 362a, the second guide surface 342a, and the third guide surface 361a can be inclined planes or arc surfaces respectively.

[0172] Example 4

[0173] The turning device of the present embodiment 4 is similar to the turning device of the above embodiment 1, except that: Figures 22 to 29 、 Figures 33 to 37As shown, the first operating portion 312 of the flipping device of this embodiment 4 includes a first guide surface 312a. The first guide surface 312a can be an inclined plane or an inclined arc surface. The plate 2 or the frame 1 can act on the first guide surface 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 or part. That is, the first guide surface 312a is formed on the first locking portion 311. When the plate 2 or the frame 1 acts on the first guide surface 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 portion 311 in the first locking space 32 or the second locking space. When the plate body 2 is inserted into the insertion channel 12, the direction in which the plate body 2 is inserted into the insertion channel 12 is set as the expansion direction, and the direction in which the plate body 2 is moved out of the insertion channel 12 is set as the folding direction; when the plate body 2 is translated along the insertion channel 12 in the expansion direction, the plate body 2 or the frame body 1 can act on the first guide 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 to generate elastic potential energy for the first elastic member 313; when the plate body 2 continues to translate 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; when the plate body 2 is translated 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.

[0174] Example 5

[0175] The turning device of the present embodiment 5 is similar to the turning device of the above embodiment 1, except that Figures 30 to 32 As shown, the limiting assembly 3 of the flip device of this embodiment 5 further includes a second limiting portion 37, 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 37 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.

[0176] When the first limiting portion 314 is provided on the plate body 2, the second limiting portion 37 is provided on the plate body 2. The first limiting portion 314 may be a protruding structure, and the second limiting portion 37 may be a protruding structure 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 have a passage through which the first limiting portion 314 passes, and the first limiting portion 314 can slide and rotate within the passage. When an external force drives the first limiting portion 314 to slide and rotate within the passage, the first limiting portion 314 can abut against the second limiting portion 37, and the second limiting portion 37 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 37 and the first limiting portion 314 are in contact with each other.

[0177] When the first position-limiting portion 314 is provided on the frame 1 or component 5, the second position-limiting portion 37 is provided on the frame 1 or component 5. Similarly, the first position-limiting portion 314 can be a protruding structure, and the second position-limiting portion 37 can be a protrusion on the frame 1 or component 5, or a portion of the frame 1 or component 5. The first operating portion 312 can drive the first position-limiting portion 314 to rotate so that the second position-limiting portion 37 and the first position-limiting portion 314 come into contact.

[0178] Example 6

[0179] The turning device of the present embodiment 6 is similar to the turning device of the above embodiment 3, except that: Figures 33 to 37 As shown, the unlocking member 36 is omitted in this embodiment 6. When the plate body 2 switches to the folded state relative to the frame body 1, the plate body 2 or the frame body 1 or the component 5 acts on the second operating portion 342 so that the third limiting portion 341 and the first limiting portion 314 no longer abut each other, and the locking member 31 switches to the first state.

[0180] When the locking cam 31 is in the closed position, the locking cam 31 is in the closed position, and the locking cam 31 is in the closed position, so that the locking cam 31 is in the closed position. When the state moves toward 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 or at least a part of the component 5, so that the plate body 2 cannot switch to the folded state; the first operating portion 312 includes an operating handle 312b, and when an external force acts on the operating handle 312b to drive the locking member 31 to move from the first state to the second state and reach the seventh state, the second elastic member 35 can drive the third limiting portion 341 to enter the third state so that the third limiting portion 341 and the first limiting portion 314 abut against each other, so that the limiting assembly 3 maintains the unlocked state; when the plate body 2 moves toward the folding direction along the insertion channel 12, at least a part of the plate body 2 or at least a part of the frame body 1 or at least a part of the component 5 can act on the second operating portion 342, so that the third limiting portion 341 and the first limiting portion 314 no longer abut against each other, so that the locking member 31 can switch to the first state.

[0181] Since the frame 1 includes the first connection portion 13 and the plate body 2 includes the second connection portion 21, in some embodiments, when the plate body 2 is translated along the insertion channel 12 in the expansion direction, at least a portion of the first connection portion 13 or at least a portion of the second connection portion 21 can act on the first guide surface 312a and switch the locking member 31 from the first state to the second state; when the plate body 2 continues to be translated in the expansion direction, at least a portion of the first connection portion 13 or at least a portion of the second connection portion 21 passes over the first locking portion 311 and makes at least a portion of the first connection portion 13 located in front of the first locking space 32, or at least a portion of the second connection portion 21 located in front of the second locking space, so that The locking member 31 switches from the second state to the first state; when the plate body 2 moves horizontally from the locked state to the folding direction, the first locking portion 311 can block at least a portion of the first connecting portion 13 or at least a portion of the second connecting portion 21, so that the plate body 2 cannot switch to the folded state; when an external force acts on the first operating portion 312 and puts the locking member 31 in the second state so that the plate body 2 can continue to move horizontally along the insertion channel 12 in the folding direction, at least a portion of the first connecting portion 13 or at least a portion of the second connecting portion 21 can act on the second operating portion 342, so that the third limiting portion 341 and the first limiting portion 314 no longer abut each other, so that the locking member 31 can switch to the first state.
