[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0038] This utility model provides a folding mechanism 50, aiming to solve the problem that the rotation point of the folding mechanism 50 in existing electric beds exceeds the folding end face, causing the mechanism to be easily damaged. (Refer to...) Figures 1 to 11The folding mechanism 50 includes a connector 10, a first folding member 201 and a second folding member 202 for fixing the furniture to be folded. The first folding member 201 and the second folding member 202 are rotatably connected to both sides of the connector 10. The first folding member 201 and the second folding member 202 are respectively provided with a first abutting end face 221 and a second abutting end face 222. When the first folding member 201 and the second folding member 202 rotate relative to the connector 10 to the folded state of the furniture, the first abutting end face 221 and the second abutting end face 222 are coplanar to form the folding end face of the folding mechanism 50, which is higher than the connector 10. The first folding member 201 and the second folding member 202 are both fixed to the frame of the furniture to be folded by welding to ensure a stable connection between the folding member and the furniture frame, thereby improving the strength and stability of the overall structure. The connector 10 is disposed between the first folding member 201 and the second folding member 202, serving as a rotational connection hub between the two folding members. The connector 10 is rotatably connected to the shaft holes of the first folding member 201 and the second folding member 202 via a pivot 30, allowing the two folding members to rotate freely around the pivot 30 of the connector 10. The first folding member 201 and the second folding member 202 are respectively provided with a first abutting end face 221 and a second abutting end face 222. When the furniture is in the folded state, the first folding member 201 and the second folding member 202 rotate relative to the connector 10 to the unfolded state. At this time, the first abutting end face 221 and the second abutting end face 222 are separated from each other but coplanar, forming the folding end face of the folding mechanism 50. This folding end face is higher than the connector 10, ensuring that the end face of the folding mechanism 50 is flat and has a certain height, facilitating the storage of the folded furniture and protecting the connector 10. Conversely, when the furniture is in the unfolded state, the first folding member 201 and the second folding member 202 rotate relative to the connecting member 10 to the folded state. At this time, the first abutting end face 221 and the second abutting end face 222 fit together, forming a tight abutting structure, which enhances the overall rigidity and stability of the folding mechanism 50 and ensures that the furniture is structurally stable and reliable when unfolded. Through the above-described folding mechanism 50, a reasonable structural transformation can be achieved in both the folded and unfolded states: in the folded state, the folding mechanism 50 unfolds, the abutting end faces separate and are coplanar, ensuring a flat folding end face; in the unfolded state, the folding mechanism 50 folds, the abutting end faces fit together, improving structural strength. The welded and fixed first folding member 201 and the second folding member 202 are tightly integrated with the furniture frame, further ensuring the durability and safety of the folding mechanism 50.

[0039] In the technical solution of this utility model, the folding mechanism 50 includes a connector 10 and a first folding member 201 and a second folding member 202 respectively rotatably connected to both sides of the connector 10. Each of the two members has an abutting end face. When the folding member is rotated to the folded state of the furniture, these abutting end faces are coplanar to form a folding end face higher than the connector 10. This ensures that the rotation point of the folding mechanism 50 is contained below or flush with the folding end face, thereby avoiding the rotation point being exposed to the outside, reducing the risk of damage caused by external impact or compression during use, and improving the structural stability and durability of the folding mechanism 50. It is particularly suitable for the folding needs of furniture such as electric beds.

[0040] In one embodiment, reference is made to Figure 2 , Figure 3 , Figure 5 and Figure 6 The connecting member 10 is further provided with a first limiting part 13, and the first folding member 201 and the second folding member 202 are provided with second limiting parts 23. When the first folding member 201 and the second folding member 202 rotate relative to the connecting member 10 to the folded state of the furniture, the first limiting part 13 abuts against the second limiting part 23. The connecting member 10 is provided with a first limiting part 13, which is usually a protruding limiting block or baffle, etc., which serves to limit the rotation range of the folding member. The first folding member 201 and the second folding member 202 are respectively provided with corresponding second limiting parts 23, which can be grooves, blocks, or protrusions, and cooperate with the first limiting part 13. During the furniture folding operation, when the first folding member 201 and the second folding member 202 rotate around the pivot 30 of the connecting member 10 to the folded state of the furniture, the first limiting part 13 and the second limiting part 23 abut against each other, forming a mechanical limit. This limiting design effectively prevents excessive rotation of the folding components, avoiding damage to the connector 10 or the pivot 30 due to excessive rotation angle, thus ensuring the structural integrity and safe use of the folding mechanism 50. Furthermore, the limiting part ensures accurate positioning of the folding components when the furniture is folded, maintaining the flatness and stability of the folding end face and preventing the overall folding effect from being affected by component misalignment. By rationally designing the shape and size of the first limiting part 13 and the second limiting part 23, precise positioning of the folding components can be achieved, improving the reliability and service life of the folding mechanism 50.

[0041] Furthermore, referring to Figure 3 , Figure 4 and Figure 9When the first folding member 201 and the second folding member 202 rotate relative to the connecting member 10 until the furniture to be folded is in the unfolded state, the first abutting end face 221 and the second abutting end face 222 coincide. When the first folding member 201 and the second folding member 202 rotate around the pivot 30 of the connecting member 10 until the furniture to be folded is in the unfolded state, the first abutting end face 221 on the first folding member 201 and the second abutting end face 222 on the second folding member 202 coincide with each other. Here, "coinciding" means that the two abutting end faces are completely aligned and fitted in space, forming a continuous and tight contact surface. This overlapping design of the abutting end faces can effectively enhance the overall rigidity and stability of the folding mechanism 50, ensuring that the furniture is structurally stable when unfolded and used, and is not prone to shaking or deformation. Through the tight fit between the first abutting end face 221 and the second abutting end face 222, the folding mechanism 50 can withstand various forces generated during the use of the furniture, improving the load-bearing capacity and service life of the furniture. Furthermore, the overlap of the abutment surfaces ensures the structural integrity of the folding mechanism 50 in the unfolded state, making the connection between the folding components more secure and preventing loose connections from affecting the normal use of the furniture. The first and second abutment surfaces contact each other and cooperate with the limiting structure to ensure accurate positioning of the folding components in the unfolded state, further enhancing the safety and reliability of the folding mechanism 50.

[0042] In one embodiment, reference is made to Figures 1 to 5The folding mechanism 50 also includes a pivot 30. The connecting member 10 includes a first plate 141, a second plate 142, a third plate 143, and a first shaft hole 11. The second plate 142 and the third plate 143 are bent along opposite sides of the first plate 141 towards the folding end face. The first shaft hole 11 is provided through the second plate 142 and the third plate 143. The first folding member 201 and the second folding member 202 are connected to the pivot 30, which is located in the first shaft. Specifically, the connecting member 10, manufactured by sheet metal stamping, is composed of a first plate 141, a second plate 142, and a third plate 143. The second plate 142 and the third plate 143 are bent along opposite sides of the first plate 141 towards the folding end face. This bending structure not only enhances the overall rigidity of the connecting member 10 but also provides a stable support position for the installation of the pivot 30. The first shaft hole 11 is through-holed into the second plate 142 and the third plate 143, forming the mounting hole 12 of the rotating shaft 30. The rotating shaft 30, as a key component connecting the first folding member 201 and the second folding member 202, passes through the first shaft hole 11, enabling a rotational connection between the first folding member 201 and the second folding member 202 and the connecting member 10. The first folding member 201 and the second folding member 202 are connected to the connecting member 10 via the rotating shaft 30. The rotating shaft 30 allows the two folding members to rotate freely relative to the connecting member 10 around its axis, thereby realizing the folding and unfolding functions of the furniture. The rotating shaft 30 ensures the rotational stability and structural strength of the folding members, preventing the folding mechanism 50 from failing due to loosening or misalignment of rotating components. The bending design of the second plate 142 and the third plate 143 in the connecting member 10 allows the rotating shaft 30 to be firmly embedded in the first shaft hole 11, preventing displacement or detachment of the rotating shaft 30 during use, thus improving the durability and safety of the folding mechanism 50. The structural design also facilitates the assembly and maintenance of the folding mechanism 50, meeting the convenience requirements of industrial production.

[0043] Furthermore, referring to Figures 1 to 4 and Figure 6The first folding member 201 and the second folding member 202 both include a fourth plate 241, a fifth plate 242, a sixth plate 243, and a second shaft hole 21. The fifth plate 242 and the sixth plate 243 are formed by bending along opposite sides of the third plate 143 in a direction away from the folding end face. The second shaft hole 21 is provided through the fifth plate 242 and the sixth plate 243, and the rotating shaft 30 is disposed in the second shaft hole 21. The first folding member 201 and the second folding member 202, manufactured by sheet metal stamping process, are both composed of the fourth plate 241, the fifth plate 242, and the sixth plate 243, wherein the fifth plate 242 and the sixth plate 243 are formed by bending along opposite sides of the third plate 143 in a direction away from the folding end face. This bending structure not only enhances the overall rigidity and load-bearing capacity of the folding member, but also provides an accurate and stable positioning position for the installation of the rotating shaft 30. The second shaft hole 21 is provided through the fifth plate 242 and the sixth plate 243, forming the mounting hole 12 for the rotating shaft 30. The rotating shaft 30 passes through the second shaft hole 21, realizing the rotatable connection between the first folding member 201 and the second folding member 202 and the rotating member. Through the connection of the rotating shaft 30, the first folding member 201 and the second folding member 202 can rotate relative to each other around the rotating shaft 30, thereby realizing the folding and unfolding function of the furniture. The setting of the rotating shaft 30 ensures the rotational flexibility and structural stability between the folding members, and avoids the failure of the folding mechanism 50 due to loosening or misalignment of the rotating parts.

[0044] In one embodiment, reference is made to Figures 1 to 5 The second plate 142 and the third plate 143 in the connector 10 have two first shaft holes 11 spaced apart along the extension direction of their bent edges. These two first shaft holes 11 provide mounting positions for the two rotating shafts 30. The two rotating shafts 30 pass through these two first shaft holes 11 and are respectively installed in the second shaft holes 21 of the first folding member 201 and the second folding member 202. The two rotating shafts 30 realize independent rotational connection between the first folding member 201 and the second folding member 202 and the connector 10, enhancing the stability and load-bearing capacity of the folding mechanism 50. The spaced arrangement of the two rotating shafts 30 effectively disperses the stress generated by the folding member during use, avoiding damage caused by excessive load on a single rotating shaft 30, thereby improving the durability and safety of the folding mechanism 50. The two pivots 30 correspond to the second shaft holes 21 of the first folding component 201 and the second folding component 202, respectively, ensuring that the rotational fit between the folding component and the connecting component 10 is precise and firm, ensuring that the folding mechanism 50 can operate smoothly during the folding and unfolding of furniture, and avoiding structural instability caused by loosening or misalignment of the pivots 30.

[0045] In one embodiment, reference is made to Figures 1 to 7The first abutting end face 221 and the second abutting end face 222 are both sides of the fourth plate 241 that are away from the fifth plate 242 and the sixth plate 243. The fourth plate 241 in the first folding member 201 and the second folding member 202 has one side that is away from the fifth plate 242 and the sixth plate 243; this side serves as the first abutting end face 221 and the second abutting end face 222. In other words, the first abutting end face 221 and the second abutting end face 222 are both located on the fourth plate 241 of their respective folding members, and this end face is located on the side away from the fifth plate 242 and the sixth plate 243 formed by the bending. This allows the first abutting end face 221 and the second abutting end face 222 to directly abut against each other, forming a stable contact surface, thereby ensuring the positioning accuracy and structural stability of the folding mechanism 50 during use, especially when the furniture is in the unfolded state. Since the abutment surface is located on the side of the fourth plate 241 away from the bending plate, interference with the bending part is avoided, improving the smoothness and reliability of the folding action. Using the original sheet metal surface as the abutment surface eliminates the need for further processing, helps to disperse the contact pressure between the folding parts, reduces local stress concentration, and extends the service life of the folding mechanism 50.

[0046] In one embodiment, reference is made to Figures 1 to 6 The first limiting part 13 is disposed on two adjacent sides of the first plate 141 and the second plate 142 or the third plate 143. When the first folding member 201 and the second folding member 202 rotate relative to the connecting member 10 to the folded state of the furniture to be folded, the second limiting part 23 is disposed on the edges of the fourth plate 241 and the fifth plate 242 near the first plate 141. When the first folding member 201 and the second folding member 202 rotate relative to the connecting member 10 to the folded state of the furniture to be folded, the first limiting part 13 is disposed on two adjacent sides of the first plate 141 and the second plate 142 or the third plate 143 of the connecting member 10. The second limiting part 23 is disposed on the edges of the fourth plate 241 and the fifth plate 242 of the first folding member 201 and the second folding member 202 near the edges of the first plate 141. The second limiting part 23 further limits the position of the folding component in the folded state, ensuring that the folding component can accurately and stably stay in the predetermined folding position, avoiding any impact on the overall folding effect and safety of the furniture due to improper positioning of the folding component. Through the coordinated action of the first limiting part 13 and the second limiting part 23, the folding mechanism 50 can effectively control the rotation range of the folding component, ensuring the smoothness and safety of the folding action, while preventing abnormal displacement or loosening of the folding component during use, further improving the reliability and durability of the folding mechanism 50.

[0047] In one embodiment, reference is made to Figures 1 to 4The folding mechanism 50 also includes a bushing 31, which is disposed between the rotating shaft 30 and the first shaft hole 11 and the second shaft hole 21. The bushing 31 serves as a connection and buffer between the rotating shaft 30 and the first and second shaft holes 11 and 21. The bushing 31 is typically made of a wear-resistant and elastic material, such as nylon, polytetrafluoroethylene, or a metal alloy, to reduce direct friction between the rotating shaft 30 and the shaft holes, reduce wear, and improve the service life of the folding mechanism 50. During the actual operation of the folding mechanism 50, the rotating shaft 30 cooperates with the first shaft hole 11 and the second shaft hole 21 through the bushing 31, allowing the rotating shaft 30 to rotate smoothly. Simultaneously, the bushing 31 effectively absorbs and disperses the frictional and impact forces generated during the operation of the rotating shaft 30, preventing direct metal-to-metal contact between the rotating shaft 30 and the shaft holes, and avoiding deformation of the shaft holes or jamming of the rotating shaft 30 due to friction. The bushing 31 also facilitates the installation and disassembly of the rotating shaft 30, improving the maintenance convenience of the folding mechanism 50. By appropriately selecting the size and material of the bushing 31, precise control of the gap between the rotating shaft 30 and the shaft hole can be achieved, ensuring that the folding mechanism 50 has good rotational flexibility and structural stability during folding and unfolding.

[0048] In one embodiment, reference is made to Figures 1 to 4 The rotating shaft 30 is also provided with a pin hole 301, in which a pin 32 is inserted. For easy disassembly, an R-type pin 32 is used. The other side of the rotating shaft 30 is also provided with a flange, which cooperates with the pin 32 to axially limit the rotating shaft 30, so that the rotating shaft 30 will not shift along its own axis when it is set in the first shaft hole 11 and the second shaft hole 21, thereby ensuring the movement stability of the entire folding mechanism 50.

[0049] This utility model also discloses an electric bed, see reference. Figures 8 to 11As shown, the folding mechanism 50 is installed on the split bed frame 40 of the electric vehicle. The bed frame 40 and the bed board 42 are both separate units. When the bed frame 40 is fully unfolded to form a single frame through the folding mechanism 50, the bed board 42 forms a flat surface for the user to lie down on. The first folding member 201 and the second folding member 202 are also provided with welding parts 25. The welding parts 25 are located on the fifth plate 242 and the sixth plate 243. In order to enhance the strength of the welded structure, the welding parts 25 are provided with two right-angled sides. These two sides can be welded to the two vertical surfaces of the square cross-section frame structure of the split bed frame 40 to form a stable three-dimensional connection structure and ensure the welding strength. When the electric bed is in the unfolded state, the first folding member 201 and the second folding member 202 rotate around the pivot 30 to their extreme positions, so that the first abutting end face 221 and the second abutting end face 222 completely overlap. At this time, the bed board 42 is laid flat on the unfolded bed frame 40, and the joint is rigidly supported by the overlapping abutting end faces, eliminating sagging gaps. In addition, the support structure of the electric bed, such as the bed legs, which forms a support between the electric bed and the ground, is fixed to the mounting holes 12 of the connector 10 by bolts or fasteners. The user can perform detachable operation of the bed legs through the mounting holes 12. When it is necessary to separate the electric bed from the ground, the support legs, such as the bed legs, are installed in the mounting holes 12, and when it is necessary to completely separate the electric bed, the support legs, such as the bed legs, are removed. When the electric bed is folded for transport, after removing the bed legs, the individual bed frames 40 are pushed to rotate around their respective pivots 30 to fold up. At this time, the first folding mirror and the second folding component 202 rotate until the first limiting part 13 abuts and locks against the two second limiting parts 23. At this point, the first abutting end face 221 and the second abutting end face 222 are coplanar to form the folding end face. The connecting piece 10 is completely hidden inside the two folding components. The folding end face serves as the outermost contour protection mechanism to avoid the risk of collision during transport. In addition, if the side of the individual bed board 42 near the connection point can also be located inside the two folding components, the bed board 42 can also be protected by the folding end face, thereby ensuring that the bed board 42 is not easily damaged during transport and ensuring the appearance and user experience of the electric bed after transport.

[0050] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
