[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] Reference Figures 1 to 8 As shown, an embodiment of the utility model provides an opening and closing hinge, including a first connecting member 1, a second connecting member 2 and at least two first connecting rods 3, one end of the two first connecting rods 3 are hinged to the first connecting member 1, the other ends of the two first connecting rods 3 are hinged to the second connecting member 2, and one of the first connecting rods 3 is located directly below the other first connecting rod 3; a suspended opening and closing component 4 is provided between each first connecting rod 3 and the second connecting member 2, so that when the first connecting rod 3 rotates relative to the second connecting member 2, there are multiple locking points between the first connecting rod 3 and the second connecting member 2.

[0032] In some practical applications, opening and closing hinges are used in bed structures:

[0033] refer to Figures 6 to 8 As shown, the bed structure also includes a bed body 7 and bed side panels 8, wherein the bed side panels 8 are located on the side of the bed body 7, a first connecting member 1 is installed on the bed body 7, and a second connecting member 2 is installed on the bed side panels 8, so that the bed side panels 8 can move between a first position and a second position on the side of the bed body 7.

[0034] In the first position, the bed side board 8 is against the side of the bed body 7 and the height of the bed side board 8 is not higher than the upper surface of the bed body 7 (such as Figure 6 and Figure 7); in the second position, the opening and closing hinges are opened to the maximum angle, and at least part of the bed side panels 8 are higher than the height of the upper surface of the bed body 7; since the bed side panels 8 are kept in a vertical state throughout the entire opening process, and the bed side panels 8 are located at or only against the side of the bed body 7 after being fully opened, it is convenient to clean, organize, etc. under the bed body 7, and the entire bed side panels 8 will not occupy too much space during the opening process, which can improve the space utilization rate of the home.

[0035] In addition, during the opening and closing process, the bed side panels 8 can have multiple locking points under the action of the hovering opening and closing assembly 4, thereby achieving stable hovering in multiple positions.

[0036] In summary, in order to realize the function of the opening and closing hinge to stably hover in the middle position, a unique hovering opening and closing component 4 is designed so that the hinge can be automatically locked when it is opened to a specific angle (such as 90°), forming a stable support structure. When the user uses the product suitable for the opening and closing hinge, the hinge can be kept hovering in the set position during the opening and closing process without additional support, thereby improving the user's convenience.

[0037] Specifically, Figure 1 As shown, a connecting portion 21 is formed on the second connecting member 2 , and the connecting portion 21 is hinged to the other end of the corresponding first connecting rod member 3 through a first pin 5 , thereby realizing the connection between the second connecting member 2 and the first connecting rod member 3 .

[0038] The hovering opening and closing component 4 can be controlled by a precise mechanical structure or electromagnetic control. In practical applications, a mechanical structure is often used for control, as follows:

[0039] refer to Figure 1 and Figure 5 As shown, the hovering opening and closing component 4 includes at least one screw 41, and a plurality of locking holes 211 distributed in a circular array are formed on the connecting portion 21. The first pin 5 is located at the center of the plurality of locking holes 211. The screw 41 is installed on the first connecting rod 3 and the elastic end of the screw 41 corresponds to the plurality of locking holes 211; when the first connecting rod 3 rotates relative to the second connecting member 2, the elastic end of the screw 41 abuts against the side wall of the connecting portion 21 or is inserted into any one of the locking holes 211.

[0040] In actual use, by pushing the product part connected to the second connecting member 2 of the opening and closing hinge, the second connecting member 2 is opened in a rotating manner while maintaining the original vertical, horizontal or other inclination state. During the whole process, the elastic end of the screw 41 always rotates between several lock holes 211. When the screw 41 leaves one of the lock holes 211 and rotates into the next lock hole 211, the locking of the point can be achieved. Without being affected by external forces such as human power, the product can be opened and closed and hovered at this point under the action of the screw 41. If the opening and closing angle of the hinge needs to be adjusted again, external forces such as human power are required to apply force to the second connecting member 2 or the product part connected thereto, so that the elastic end of the screw 41 can be separated from the existing locking and enter the next lock hole 211, so as to achieve the adjustment of the opening and closing angle of the opening and closing hinge and multi-point hovering.

[0041] Specifically, the hinge line at one end of the two first link members 3 is always parallel to the hinge line at the other end of the two first link members 3, thereby ensuring that the hinge structure can open and close smoothly and avoiding structural dead points that cause the opening and closing hinge to fail to open and close smoothly.

[0042] In some applications:

[0043] The opening and closing hinge also includes a second connecting rod 6 (such as Figure 4 , 5 , 6), the two ends of the second link member 6 are respectively hinged to the two first link members 3, and the line connecting the two hinge points of the second link member 6 is always parallel to the line connecting the hinge points of one end of the two first link members 3.

[0044] By setting the second connecting rod 6, the hinge can avoid shaking due to being extended too long when opening or hovering in the middle. By increasing the structural rigidity and stability, the green hinge can ensure the stability of the entire hinge assembly during movement.

[0045] The second link member 6 is a key adjustment component for accurately controlling the opening and closing synchronization of the two first link members 3. By adjusting the second link member 6, the synchronization and consistency of the entire hinge structure during the movement can be ensured, thereby meeting the needs of specific applications.

[0046] The second connecting rod 6 has a special structural design (such as Figure 2 As shown), it is possible to provide additional support for the two first rods, thereby enhancing the stability of the entire hinge assembly.

[0047] The design of the opening and closing hinge takes into account the smoothness and stability of the opening and closing action, ensuring that it remains stable and smooth during the opening and closing process.

[0048] When the opening and closing hinge is still used in the above bed structure:

[0049] The opening and closing hinges are configured in two groups and are respectively located at the two ends of the bed side plate 8 (such as Figure 6 and Figure 7 ); The two hinges are to ensure the synchronization and stability of the structural movement:

[0050] Double hinges enhance structural stability: Two hinges used together can form a more stable structure, which reduces wear and deformation of a single hinge by sharing loads and stresses, thereby improving the durability of the entire mechanism.

[0051] Synchronicity: The two hinges work simultaneously to ensure the synchronization of the mechanism during movement and avoid instability in the movement of the entire mechanism.

[0052] Specifically, a balance bar 9 (such as Figure 6 and Figure 7 The balance bar 9 is mainly used to make the span of the hinges on both sides larger, to ensure the synchronization and consistency of the two hinges when opening, and to prevent the left and right sides from being out of sync, resulting in inconsistent opening heights and uneven opening of the left and right sides, and the problem of unsmooth opening; adding the balance bar 9 effectively solves this problem.

[0053] In addition, it should be noted that the application of the opening and closing hinge is not limited to the above-mentioned bed structure, but can also be applied to at least the following fields:

[0054] 1. Home doors and windows: Suitable for various casement windows, casement doors and other home doors and windows, providing convenient opening and closing operations and safe hovering functions. The 180° opening and closing angle can expand the sense of indoor space and enhance the living experience.

[0055] 2. Industrial equipment: It can be used for heavy-duty electrical cabinet doors, distribution boxes and other equipment to meet the needs of a large range of opening and closing. The hovering function can ensure that the equipment hovers stably in the open state, which is convenient for maintenance and operation.

[0056] 3. Electronic equipment: Suitable for the housing or panel of various electronic equipment, providing convenient opening and closing operation and stable hovering state. Advanced control mechanism can ensure the stability and safety of electronic equipment.

[0057] 4. Special occasions: This hinge can also play an excellent role in some special occasions that require large-scale opening and closing and stable hovering (such as display cabinets, exhibition stands, etc.).

[0058] When the opening and closing hinge is used in different occasions, the user is allowed to adjust the maximum opening and closing angle of the hinge according to actual needs, ensuring that the needs can be met in different application occasions. The hinge can stably achieve an opening and closing angle of 180° through the design of at least two first connecting rods 3 and the suspended opening and closing component 4. At the same time, the hinge also takes into account the stability and safety of the structure, ensuring that the hinge can still maintain stable operation at the maximum opening and closing angle.

[0059] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
