Technical Field

[0001] This utility model specifically relates to an automatically opening and closing invisible hinge. Background Technology

[0002] Concealed hinges are a type of hardware widely used in various doors and windows. Their main function is to enable the opening and closing of doors and windows, and due to their concealed design, they can enhance the aesthetics of doors and windows to a certain extent. Traditional concealed hinges are mostly operated manually, requiring the user to push or pull the door or window to open and close it.

[0003] For example, Chinese utility model patent document with publication number "CN220036422U" discloses an invisible hinge, which mainly consists of a mounting box, a receiving box, a main shaft, a support arm, a connecting arm, and a swing arm. This invisible hinge must be operated manually, and the opening and closing action is achieved by manually pushing or pulling the door or window. It cannot realize intelligent functions such as automatic opening and closing, speed adjustment, and remote control. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an automatic opening and closing invisible hinge that addresses the shortcomings of the prior art. It is equipped with an electric drive mechanism, enabling the invisible hinge to achieve automatic opening and closing without manual operation and facilitating remote control.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatically opening and closing invisible hinge, comprising a mounting box, a receiving box, and a multi-level hinge linkage mechanism, wherein the mounting box and the receiving box are linked by the multi-level hinge linkage mechanism, characterized in that: the multi-level hinge linkage mechanism is linked to an electric drive mechanism, which is used to drive the multi-level hinge linkage mechanism to work, thereby controlling the opening and closing of the invisible hinge.

[0006] By adopting the above technical solution and incorporating an electric drive mechanism, the concealed hinges can achieve automatic opening and closing, eliminating the need for manual operation and facilitating remote control. Furthermore, by controlling the output speed and torque of the power source, not only can speed adjustment and remote control functions be further realized, but adjustments can also be made according to different door weights and usage scenarios to adapt to more complex working conditions.

[0007] The aforementioned automatic opening and closing concealed hinge can be further configured such that: the electric drive mechanism includes a motor and a transmission component linked to the output end of the motor, and the transmission component is linked to a multi-stage hinge linkage mechanism.

[0008] Using the above technical solution, the hinges can open and close automatically via motor drive, eliminating the need for manual operation. By adjusting the motor's speed or torque, the opening speed of the concealed hinges can be changed. In addition to ordinary door panels, it can also be applied to door panels that require frequent opening and closing or remote control. Meanwhile, the transmission component can be either gear drive or linkage drive, as long as it can transmit the motor's output torque to the main shaft.

[0009] The aforementioned automatic opening and closing concealed hinge can be further configured such that: the multi-stage hinge linkage mechanism includes a main shaft, and the transmission component includes a main drive wheel linked to the output end of the motor and a secondary drive wheel linked to the end of the main shaft, wherein the main drive wheel and the secondary drive wheel are linked.

[0010] Using the above technical solution, the main shaft is used to support and transmit the motor's power. It should be noted that the main shaft in this solution is fundamentally different from the functional shafts in existing technologies. The main shaft proposed in this solution does not require internal components for "hydraulic buffering"; any component capable of "torque transmission" is acceptable, and functional shafts are not excluded.

[0015] The aforementioned automatic opening and closing concealed hinge can be further configured as follows: the receiving seat includes two sets of second sidewalls respectively placed at both ends of the main shaft, each set of second sidewalls is provided with a second adjusting plate, the receiving housing is provided with a groove for placing the second adjusting plate, both the second adjusting plate and the groove are provided with through holes for adjusting screws to pass through, and the second adjusting plate is threadedly connected to the adjusting screw.

[0016] Using the above technical solution, the adjusting screw is threadedly connected to the second adjusting plate. After the adjusting screw passes through the groove, it is inserted into the door leaf. When the adjusting screw is rotated, the adjusting screw does not separate from the door leaf. The threaded connection drives the second adjusting plate, which can move along the adjusting screw in the groove. This drives the accommodating seat to move along the adjusting screw in the accommodating housing, thereby realizing the adjustment of the installation depth of the accommodating seat in the accommodating housing.

[0017] The aforementioned automatic opening and closing concealed hinge can be further configured as follows: the multi-stage hinge linkage mechanism further includes a support arm, a connecting arm, and a swing arm; the main shaft is provided with a hinge portion protruding from its surface; the swing arm includes a swing arm shaft connected to the mounting box and swing arms provided at both ends of the swing arm shaft; the connecting arm includes a first support block hinged to both swing arms and a first connecting shaft connected to the receiving box; the first connecting shaft is provided with a second support block; the second support block is connected to the first support block through a first connecting section; the support arm includes a second connecting shaft connected to the mounting box; both ends of the second connecting shaft are provided with a first support arm, a second arm hinged to the hinge portion, and a second connecting section connecting the first support arm and the second arm; the first connecting section is hinged to both second connecting sections simultaneously.

The two first arms set on it are simultaneously connected to the hinge part, which increases the contact area of ​​the hinge part. During use, it prevents the hinge part on the main shaft from breaking, improves the connection stability between the main shaft and the support arm, and extends the service life of the hinge.

[0019] The aforementioned automatic opening and closing invisible hinge can be further configured as follows: the mounting box includes a separately configured mounting base and a mounting housing, the mounting base is embedded in the mounting housing, the mounting base includes a mounting plate placed in the mounting housing and first sidewalls vertically arranged at both ends of the mounting plate, each of the two first sidewalls is provided with a first adjusting plate parallel to the mounting plate, each of the two first adjusting plates is provided with a first oblong hole, the mounting housing is provided with a second oblong hole intersecting the first oblong hole at the corresponding location, and a fastener connecting the second oblong hole passes through the first oblong hole.

The direction of movement of the mounting base is the axial direction of the two oblong holes. The two oblong holes are arranged perpendicularly to each other in opposite planes, that is, the mounting base can move up, down, left, and right on the horizontal plane.

Detailed Implementation

[0027] 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.

[0028] like Figures 1 to 4The illustrated automatic opening and closing concealed hinge includes a mounting box 1, a receiving box 2, and a multi-stage hinge linkage mechanism 3. The mounting box 1 and the receiving box 2 are linked by the multi-stage hinge linkage mechanism 3. The multi-stage hinge linkage mechanism 3 is linked to an electric drive mechanism 4, which drives the multi-stage hinge linkage mechanism 3 to work, thereby controlling the opening and closing of the concealed hinge.

[0029] The multi-stage hinge linkage mechanism 3 includes a main shaft 31, a support arm 32, a connecting arm 33, and a swing arm 34. The main shaft 31 is provided with a hinge part 311 protruding from its surface. The swing arm 34 includes a swing arm shaft 341 connected to the mounting box 1 and swing arms 342 provided at both ends of the swing arm shaft 341. The connecting arm 33 includes a first support block 331 that is simultaneously hinged to the two swing arms 342 and a first connecting shaft 332 that is connected to the receiving box 2. The first connecting shaft 332 is provided with a second support block 333. The second support block 333 is connected to the first support block 331 through a first connecting section 334. The support arm 32 includes a second connecting shaft 321 that is connected to the mounting box 1. Both ends of the second connecting shaft 321 are provided with a first support arm 322, a second support arm 323 that is hinged to the hinge part 311, and a second connecting section 324 that connects the first support arm 322 and the second support arm 323. The first connecting section 334 is simultaneously hinged to both second connecting sections 324.

[0030] The main shaft 31 supports and transmits the power of the motor. Furthermore, the main shaft 31 is hinged to the support arm 32, which replaces the connecting arm 33 as an intermediate component for transmitting torque. Two first arms 322 on the support arm 32 are simultaneously connected to the hinge portion 311, increasing the contact area of ​​the hinge portion. This prevents the hinge portion 311 on the main shaft 31 from breaking during use, improves the connection stability between the main shaft 31 and the support arm 32, and extends the service life of the hinge. It should be noted that the main shaft 31 in this embodiment is fundamentally different from the functional shaft in the prior art. The main shaft 31 proposed in this embodiment does not require internal components for "hydraulic buffering." Any component capable of "torque transmission" can be used; the functional shaft is not excluded. The auxiliary drive wheel 43 is linked with the main drive wheel 42, further transmitting power to the multi-stage hinge linkage mechanism 3 to realize the opening and closing action of the concealed hinge.

[0031] The electric drive mechanism 4 includes a motor 41 and a transmission assembly. The transmission assembly includes a main drive wheel 42 linked to the output end of the motor 41, a secondary drive wheel 43 linked to the end of the main shaft 31, and a set of driven wheels 44. One side of the driven wheel 44 meshes with the main drive wheel 42 for transmission, and the other side of the driven wheel 44 meshes with the secondary drive wheel 43 for transmission. Driven by the motor 41 and with torque transmitted by the transmission assembly, the hinge can open and close automatically without manual operation. By adjusting the speed or torque of the motor 41, the opening speed of the concealed hinge can be changed. In addition to ordinary door panels, it can also be used for door panels that require frequent opening and closing or require remote control. At the same time, the transmission assembly can be made of gear transmission or linkage transmission, as long as it can transmit the output torque of the motor to the main shaft.

[0032] The housing 2 includes a separate housing base 21 and a housing shell 22, facilitating the installation and disassembly of the motor 41 and the gear transmission assembly 44. Both ends of the main shaft 31 are rotatably mounted on the housing base 21. The housing base 21 has mounting grooves 211 corresponding to the ends of the main shaft 31 for mounting the main drive wheel 42, driven wheel 44, and auxiliary drive wheel 43. The housing shell 22 has mounting cavities 221 corresponding to the sides of the main shaft 31 for mounting the motor 41. The housing base 21 includes two sets of second sidewalls 212 respectively located at both ends of the main shaft 31. Each set of second sidewalls 212 has a second adjusting plate 213. The housing shell 22 has grooves 222 for placing the second adjusting plates 213. Both the second adjusting plates 213 and the grooves 222 have through holes for adjusting screws to pass through. The second adjusting plates 213 are threadedly connected to the adjusting screws. The adjusting screw is threadedly connected to the second adjusting plate 213. After passing through the groove 222, the adjusting screw is inserted into the door leaf. When the adjusting screw is rotated, the adjusting screw does not separate from the door leaf. The threaded connection drives the second adjusting plate 213, which can move along the adjusting screw in the groove 222. This causes the receiving seat 21 to move along the adjusting screw in the receiving housing 22, thereby adjusting the installation depth of the receiving seat 21 in the receiving housing 22.

[0033] Mounting box 1 includes a separate mounting base 11 and a mounting housing 12. The mounting base 11 is embedded in the mounting housing 12. The mounting base 11 includes a mounting plate 111 placed inside the mounting housing 12 and first sidewalls 112 vertically arranged at both ends of the mounting plate 111. Each of the two first sidewalls 112 is provided with a first adjusting plate 113 parallel to the mounting plate 111. Each of the two first adjusting plates 113 is provided with a first oblong hole 114. The mounting housing 12 is provided with a second oblong hole 121 that is intersected with the first oblong hole 114 at the corresponding location. Fasteners that connect to the second oblong hole 121 are inserted into the first oblong hole 114. Two oblong holes are provided on the mounting base 11 and the mounting housing 12 respectively, for adjusting the relative position of the mounting base 11 within the mounting housing 12. The moving direction of the mounting base 11 is the axial direction of the two oblong holes. The two oblong holes are arranged perpendicularly to each other, meaning that the mounting base 11 can move up, down, left, and right on the horizontal plane. The position of the mounting base 11 can be adjusted without removing the mounting housing 12 from the door leaf, which facilitates the installation of the hinge.

[0034] Compared with the concealed hinges provided by the prior art, the concealed hinge provided in this embodiment adopts a motor 41 drive, which can realize remote control, automatic opening and closing of the concealed hinge, and adjustment of the motor 41 speed according to different working conditions. After the motor 41 starts, the torque is transferred to the main shaft 31 through the transmission component. The specific actions of the main shaft 31, support arm 32, connecting arm 33, swing arm 34 and other structures are the same as in the prior art, so they will not be described again in this embodiment.
