[0044] Referring to Figure 2 and Figure 6 According to some embodiments of the present application, the buffer energy storage device 400 includes a housing 410, an output slide block 420 and an input slide block 430, the output slide block 420 and the input slide block 430 are slidably mounted on the housing 410, the output slide block 420 is in transmission connection with the first connecting seat 110, the input slide block 430 is in transmission connection with the output part of the driving device 200, and the output slide block 420 and the input slide block 430 are in transmission through the elastic buffer member 440. Thus, during the relative rotation of the first connecting seat 110 and the second connecting seat 120, if the door and window collide with other objects, the elastic buffer member 440 can be contracted or elongated, so that the output slide block 420 can remain stationary, and the driving device 200 can drive the input slide block 430 to continue sliding to the maximum stroke, thereby forming a buffering effect, protecting the driving device 200, and avoiding strong collision between the door and window and other objects. At the same time, the elastic buffer member 440 can store the energy provided by the driving device 200 during deformation, and when the door and window are no longer hindered, the input slide block 430 remains stationary, and the output slide block 420 can be re-slid under the drive of the elastic buffer member 440, so that the first connecting seat 110 and the second connecting seat 120 continue to rotate relative to each other, thereby completing the opening and closing of the door and window.

[0048] Of course, other transmission modes can also be adopted between the buffer energy storage device 400 and the clutch device 300, for example, the transmission mode in which the lead screw 460 is matched with the transmission nut 450 can be replaced by a transmission mode in which a gear is matched with a rack.

[0049] Referring to Figure 1 and Figure 2According to some embodiments of the utility model, the driving device 200, the clutch device 300, the buffer energy storage device 400, the rotating speed control device 500 and the load-bearing hinge 100 can be disassembled in a modular manner, so that the driving device 200, the clutch device 300, the buffer energy storage device 400 and other devices are all arranged as separate modules, each module can be disassembled, which facilitates installation and replacement in later maintenance, and facilitates structural upgrading of a certain module in later period. In addition, the load-bearing hinge 100 can be used alone, and consumers can also increase or decrease the rotating speed control device 500, the buffer energy storage device 400, the clutch device 300 and the driving device 200 on the basis of the load-bearing hinge 100 according to actual needs.

[0053] It should be noted that there are various types of hinges in the technical field, and the load-bearing hinge 100 described above can also be arranged according to the structure of the existing hinge, and the specific arrangement mode is not described in detail here.

[0054] With reference to Figure 2 and Figure 7In some embodiments, the rotating speed control device 500 can be a hydraulic speed regulator. Specifically, the rotating speed control device 500 comprises a speed regulating seat 510 and a piston 520, the speed regulating seat 510 is detachably connected with the second connecting seat 120, the speed regulating seat 510 is provided with a speed regulating cavity 513 and two first oil paths 511, each of the first oil paths 511 is communicated with the speed regulating cavity 513 through two communication ports 512, one of the two communication ports 512 of one of the first oil paths 511 is close to the middle of the speed regulating cavity 513, and the other of the two communication ports 512 of the other of the first oil paths 511 is close to one end of the speed regulating cavity 513, the piston 520 is slidably installed in the speed regulating cavity 513, one end of the piston 520 is connected with a first transmission rod 530, the other end of the piston 520 is connected with a second transmission rod 540, the first transmission rod 530 is in transmission connection with the first connecting seat 110, and the buffer energy storage device 400 is in transmission connection with the second transmission rod 540. Thus, the speed regulating cavity 513 and the first oil paths 511 can be filled with hydraulic oil, and the hydraulic oil on one side of the piston 520 flows to the other side of the piston 520 through the first oil paths 511 during the sliding of the piston 520 along the axial direction of the speed regulating cavity 513, wherein, when the piston 520 is close to the middle of the speed regulating cavity 513, the first oil paths 511 through which the hydraulic oil flows are more, so that the sliding resistance of the piston 520 is small, and when the piston 520 is close to the end of the speed regulating cavity 513, the first oil paths 511 through which the hydraulic oil flows are less, so that the sliding resistance of the piston 520 is large. Therefore, through the rotating speed control device 500, the rotating speed of the first connecting seat 110 relative to the second connecting seat 120 is small at the initial position, large at the middle position, and small at the end position, thereby avoiding the situation that the rotating speed of the door and window is too large at the maximum opening angle position and the closed position, reducing the impact on the door and window when the door and window collides with other objects, and reducing the accidents of people being hit during the opening and closing of the door and window. The buffer energy storage device 400 can reduce the impact on the driving device 200 caused by the rotating speed control device 500 during the control of the rotating speed, and avoid the overloading of the driving device 200 caused by the rotating speed control device 500.

[0055] Referring to Figure 7In the specific implementation process, the rotation axis between the first connecting seat 110 and the second connecting seat 120 is perpendicular to the axial direction of the speed regulation cavity 513, the first oil channel 511 is arranged along the axial direction of the speed regulation cavity 513, the second connecting seat 120 is provided with a relief hole corresponding to the first oil channel 511, the first oil channel 511 is screwed with a speed regulation bolt 550, one end of the speed regulation bolt 550 extends to the communication port 512 of the first oil channel 511 close to the second connecting seat 120, thereby, after the first connecting seat 110 and the second connecting seat 120 are relatively rotated to be opened, the speed regulation bolt 550 can be operated from the relief hole, and then the effective communication area between the first oil channel 511 and the speed regulation cavity 513 is adjusted, thereby controlling the flow of hydraulic oil in the first oil channel 511, changing the sliding resistance of the piston 520 in the speed regulation cavity 513, and finally adjusting the relative rotation speed between the first connecting seat 110 and the second connecting seat 120, and the speed regulation is convenient and simple.

[0056] In some embodiments, the piston 520 is provided with a second oil channel 521, and a one-way valve piece is arranged in the second oil channel 521, when the first connecting seat 110 and the second connecting seat 120 are relatively rotated to open the door and window, the one-way valve piece opens the second oil channel 521, so that the hydraulic oil on one side of the piston 520 can also flow to the other side of the piston 520 through the second oil channel 521, thereby reducing the resistance brought by the rotation speed control device 500, so that the door and window are opened with less labor. When the first connecting seat 110 and the second connecting seat 120 are relatively rotated to close the door and window, the one-way valve piece closes the second oil channel 521, so as to avoid the influence of the second oil channel 521 on the work of the rotation speed control device 500.

[0057] In the specific implementation process, a reset spring can be arranged between the piston 520 and the speed regulation seat 510, the piston 520 is driven to reset by the reset spring, and then the door and window are automatically closed, thereby, the rotation speed control device 500 can also have a certain buffering and self-closing function.

[0058] It can be imagined that the above-mentioned rotating speed control device 500 can also adopt other settings, for example, the rotating speed control device 500 can be set in a pure mechanical form, specifically, the damping block is provided on the two sides of the speed regulating chamber 513 in the radial direction, the damping block is provided with a V-shaped groove, the piston 520 is located in the V-shaped groove, the damping block is slidingly installed on the speed regulating seat 510, and a reset structure is arranged between the damping block and the speed regulating seat 510. The reset structure can be a magnetic reset structure or an elastic reset piece. Therefore, when the piston 520 slides to the end of the speed regulating chamber 513, the sliding distance of the piston 520 pushing the damping block is large, and the resistance of the piston 520 is also large. When the piston 520 slides to the middle position of the speed regulating chamber 513 in the axial direction, the sliding distance of the piston 520 pushing the damping block is small, and the damping of the piston 520 is also small. Therefore, through the rotating speed control device 500, the relative rotating speed of the first connecting seat 110 and the second connecting seat 120 is small at the initial position, large at the middle position, and small at the end position. By adjusting the force of the reset structure on the damping block, the damping force of the piston 520 can be adjusted.

[0059] It should be noted that in other embodiments, the above-mentioned rotating speed control device 500 can also be installed on the first connecting seat 110. At this time, the rotating speed control device 500 does not need to be in driving connection with the buffer energy storage device 400.

[0060] The automatic system for doors or windows according to the second aspect of the present application comprises the automatic opening and closing rotating connection mechanism. By using the above-mentioned rotating connection mechanism, the rotating connection of the door or window can be realized, and the automatic opening and closing of the door or window can be realized. The integrated design of the hinge and the door opening mechanism is realized, and the installation space requirement is reduced.

[0061] Referring to Figure 8 In some embodiments, the automatic system further comprises a fixed frame 600, one of the first connecting seat 110 and the second connecting seat 120 is fixedly installed on the fixed frame 600, and the other is fixedly connected with a window body or a door body 700. When the driving device 200 drives the relative rotation of the first connecting seat 110 and the second connecting seat 120, the window body or the door body 700 can open and close the fixed frame 600. In the specific implementation process, the driving device 200 and other components of the rotating connection mechanism can be inserted or completely accommodated in the door body 700 or the window body. Therefore, the installation space required by the rotating connection mechanism overlaps with the installation space of the door or window, thereby reducing the installation space requirement. In addition, the driving device 200 and other components of the rotating connection mechanism can be hidden by the door or window, avoiding the exposure of the driving device 200. On the one hand, the driving device 200 and other devices can be protected, maintenance can be reduced, and the service life can be improved. On the other hand, the overall appearance of the door or window can be ensured, and the sense of technology can be enhanced.

[0062] In the implementation process, the fixing frame 600 can be a vehicle frame, or a wall or door frame at a building doorway or window.

[0063] In the implementation process, the driving device 200 is provided with a control device, which can be electrically connected to the rotation angle detection element. The control device detects the rotation angle of the first connecting seat 110 relative to the second connecting seat 120 through the rotation angle detection element. In order to realize automatic opening and closing of the door and window, the control device is built-in AI, which memorizes the opening angle and closing angle of the door and window through the AI. The circuit board of the control device can be partially arranged in the housing of the driving device 200. Of course, the control device can also be arranged elsewhere, and then the control device is connected to the driving device 200 through signals. The control device can be configured with one or more than two function modules such as a door lock module, a voice recognition module, a fingerprint recognition module, and a camera module.

[0064] The technical features of the above-described embodiments can be combined arbitrarily.

[0065] The embodiments of the utility model have been described in detail above in combination with the drawings, but the utility model is not limited to the above-described embodiments. Various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the utility model.
