[0033] Reference Figure 1 , Figure 2 and Figure 8 The rotating connection mechanism of the automatic switch according to the first aspect of the embodiment of the present invention includes a load-bearing hinge 100 and a driving device 200. The load-bearing hinge 100 includes a first connecting seat 110 and a second connecting seat 120. The second connecting seat 120 is rotatably connected to the first connecting seat 110; the driving device 200 is installed on the second connecting seat 120. The driving device 200 is transmission-connected to the first connecting seat 110. The driving device 200 is used to drive the first connecting seat 110 and the second connecting seat 120 to rotate relative to each other.

[0034] The rotating connection mechanism provided by the present invention, whose load-bearing hinge 100 can be used for the rotating connection of doors or windows to bear the weight of the door or window and realize the rotation of the door or window, and the driving device 200 can drive the first connecting seat 110 and the second connecting seat 120 to rotate relative to each other, so as to realize the automatic opening and closing of the door or window. Therefore, the driving device 200 and the load-bearing hinge 100 are installed in one place to realize the integrated design of the hinge and the door opening mechanism. It can be installed in the installation position of ordinary hinges in existing doors and windows to replace the ordinary hinges, without the need for other additional installation positions, thereby reducing the installation space requirements.

[0035] Reference Figure 8 In the specific implementation process, the driving device 200 and other components of the rotating connection mechanism can be partially inserted or completely stored in the door body 700 or the window body, so that the installation space required for 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 to avoid the driving device 200 being exposed to the outside. On the one hand, it can protect the driving device 200 and other devices, reduce maintenance, and increase service life. On the other hand, it ensures the overall appearance of the door or window and enhances the sense of technology.

[0036] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, a clutch device 300 is provided between the output portion of the driving device 200 and the first connecting seat 110, wherein the output portion of the driving device 200 can drive the first connecting seat 110 to rotate relative to the second connecting seat 120 through the clutch device 300, and the clutch device 300 can limit the first connecting seat 110 from driving the output portion of the driving device 200. Therefore, when an external force such as human power or wind force drives the first connecting seat 110 and the second connecting seat 120 to rotate relative to each other, the clutch device 300 can disconnect the transmission connection between the driving device 200 and the first connecting seat 110, thereby protecting the driving device 200, the transmission components between the driving device 200 and the first connecting seat 110, and other components when the external force drives the rotating connection mechanism. In addition, when the driving device 200 loses power, fails, or other factors occur, resulting in the need to manually drive the first connecting seat 110 and the second connecting seat 120 to rotate relative to each other to open and close the doors and windows, the resistance inside the driving device 200 can be avoided to form an obstacle, making it effortless to open and close the doors and windows manually, thereby realizing manual opening of the doors and windows.

[0037] Reference Figure 1 and Figure 2According to some embodiments of the present invention, the rotation connection mechanism further includes a buffer energy storage device 400, the buffer energy storage device 400 is installed on the second connection seat 120, the driving device 200 is installed on the buffer energy storage device 400, the driving device 200, the buffer energy storage device 400 and the first connection seat 110 are sequentially connected in a transmission manner, and the buffer energy storage device 400 is used to buffer and store energy for the force transmitted between the driving device 200 and the first connection seat 110. Therefore, during the relative rotation process between the first connection seat 110 and the second connection seat 120, if the door and window collide with other objects, the buffer energy storage device 400 can play a buffering role between the driving device 200 and the first connection seat 110, protect the driving device 200, and prevent the door and window from colliding strongly with other objects. At the same time, the buffer energy storage device 400 stores the energy provided by the driving device 200. When the obstacles to the door and window are eliminated, the buffer energy storage device 400 drives the first connection seat 110 and the second connection seat 120 to continue to rotate relative to each other by relying on the stored energy. When the rotating connection mechanism is provided with a clutch device 300 and a buffer energy storage device 400 at the same time, during the manual driving of the rotating connection mechanism, the clutch device 300 can reduce the reverse force provided by the buffer energy storage device 400, making manual driving more labor-saving.

[0038] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, the rotating connection mechanism also includes a speed control device 500, which is installed on the second connecting seat 120 or the first connecting seat 110. The speed control device 500 is used to adjust the speed during the relative rotation of the first connecting seat 110 and the second connecting seat 120 to avoid excessive speed.

[0039] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, the speed control device 500 is installed on the second connecting seat 120, the buffer energy storage device 400 is installed on the speed control device 500, the driving device 200 is connected to the buffer energy storage device 400 through the clutch device 300, and the buffer energy storage device 400, the speed control device 500 and the first connecting seat 110 are sequentially connected. Through the above arrangement, the driving device 200, the clutch device 300, the buffer energy storage device 400 and the speed control device 500 can cooperate with each other to solve various situations encountered by the rotating connection mechanism during use, and improve the effects of the rotating connection mechanism in preventing collision and impact, preventing overload, and saving labor when opening the door manually. In addition, by adopting the above layout, each device is more convenient to install, the overall shape of the rotating connection mechanism is more beautiful, and the size is more reasonable, which is conducive to controlling the overall size of the rotating connection mechanism.

[0040] Reference Figures 2 to 4According to some embodiments of the present invention, the clutch device 300 includes a mounting seat 310, a clutch block 320, a clamping piece 330 and a clutch sleeve 340. The mounting seat 310 is fixedly installed between the driving device 200 and the second connecting seat 120. The output portion of the driving device 200 is arranged on the mounting seat 310 and is fixedly connected to the clutch block 320. The clutch sleeve 340 is transmission-connected to the first connecting seat 110. The clutch sleeve 340 is provided with an accommodating cavity 341. The inner peripheral wall of the accommodating cavity 341 is provided with a clamping structure 342 that cooperates with the clamping piece 330. The clamping structure 342 includes two slots 3421 arranged at intervals. The clutch block 320 is located in the accommodating cavity 341. A mating surface 321 is provided on the outer periphery of the clutch block 320. There is a clutch between the mating surface 321 and the inner wall of the accommodating cavity 341. The clamping member 330 is located in the clutch gap 343, the mounting seat 310 covers the accommodating chamber 341, the clamping member 330 and the mounting seat 310 are magnetically matched, and the clamping member 330 and the clutch block 320 are magnetically matched, wherein, during the process in which the output part of the driving device 200 drives the clutch block 320 to rotate relative to the mounting seat 310, the mounting seat 310 and the matching surface 321 cooperate with each other to drive the clamping member 330 to enter and exit one of the slots 3421 of the clamping structure 342, so that the clutch sleeve 340 and the clutch block 320 are clutched, and when the clutch sleeve 340 rotates relative to the clutch block 320 to increase the interval between the slot 3421 and the matching surface 321, the clamping member 330 is disengaged from the slot 3421 under the magnetic attraction between the clamping member 330 and the clutch block 320. Through the clutch device 300, no matter whether the driving device 200 drives the clutch block 320 to rotate forward or reverse, the driving device 200 can automatically engage and disengage with the first connecting seat 110, and when the first connecting seat 110 is driven to rotate relative to the second connecting seat 120 by external forces such as manpower or wind, the clutch device 300 can disconnect the transmission connection between the first connecting seat 110 and the driving device 200. The clutch device 300 can engage and disengage automatically without the need for an additional operating structure, has a simple structure, is easy to install, has a low cost, is reliable in operation, and has a long service life.

[0041] Reference Figure 3 and Figure 4 In some embodiments, the clutch block 320 is provided with mating surfaces 321 at both opposite ends, and the clamping member 330 is also provided with two and one-to-one corresponding mating surfaces 321, and correspondingly, the above-mentioned clamping structure 342 is also provided with two groups, so that the inner wall of the accommodating cavity 341 has four clamping grooves 3421. Through the above arrangement, the stability of the clutch device 300 during the clutch process can be improved.

[0042] In the specific implementation process, the clutch block 320 can be set as a magnet, and the clamping member 330 and the mounting seat 310 can be made of magnetic materials such as iron, cobalt, and nickel. Therefore, the clutch block 320 can magnetically attract the clamping member 330, and the mounting seat 310 can also magnetically attract the clamping member 330 under the action of the clutch block 320. Of course, in other embodiments, the mounting seat 310 can also be set as a magnet, and the clamping member 330 can also be set as a magnet.

[0043] Of course, the clutch device 300 mentioned above may also adopt a clutch in the prior art, and the specific configuration will not be described in detail here.

[0044] Reference Figure 2 and Figure 6 According to some embodiments of the present invention, the buffer energy storage device 400 includes a housing 410, an output slider 420 and an input slider 430. The output slider 420 and the input slider 430 can be relatively slidably installed on the housing 410. The output slider 420 is transmission-connected to the first connecting seat 110, and the input slider 430 is transmission-connected to the output part of the driving device 200. The output slider 420 and the input slider 430 are transmission-connected through an elastic buffer 440. Therefore, during the relative rotation of the first connecting seat 110 and the second connecting seat 120, if the door or window collides with other objects, the elastic buffer 440 can shrink or stretch, so that the output slider 420 can remain stationary and the driving device 200 can drive the input slider 430 to continue to slide to the maximum stroke, thereby forming a buffering effect, protecting the driving device 200, and avoiding strong collisions between the door or window and other objects. At the same time, the elastic buffer 440 can store the energy provided by the driving device 200 during the deformation process. When the obstruction to the door or window is eliminated, the input slider 430 remains stationary, and the output slider 420 can slide again under the drive of the elastic buffer 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 or window.

[0045] Reference Figure 2 and Figure 6In the specific implementation process, the output slider 420 is provided with a slot 421, the input slider 430 can be slidably inserted in the slot 421, the input slider 430 is provided with a first clamping structure 431, the first clamping structure 431 includes two first clamping parts 4311, each elastic buffer 440 can be installed between the two first clamping parts 4311 of the corresponding first clamping structure 431, the output slider 420 is provided with a second clamping structure 422, the second clamping structure 422 includes two second clamping parts 4221, each elastic buffer 440 is located between the two second clamping parts 4221 of the corresponding second clamping structure 422, so that the output slider 420 and the input slider 430 can shrink the elastic buffer 440 whether they slide away from each other or slide close to each other, so that the buffer energy storage device 400 can realize the buffering and energy storage effect by shrinking the elastic buffer 440 whether the first connecting seat 110 and the second connecting seat 120 rotate forward or reverse. Through the above arrangement, during the operation of the buffer energy storage device 400 , the elastic buffer component 440 will only be compressed and will not be alternately stretched and compressed, so the elastic buffer component 440 can have a longer service life.

[0046] It is conceivable that the above-mentioned buffer energy storage device 400 can also be arranged in other ways. For example, the output slider 420 and the input slider 430 can cooperate with each other to generate mutually repulsive magnetic forces. Thus, the mutually repulsive magnetic forces can be used to replace the elastic force of the above-mentioned elastic buffer 440. Specifically, a first magnet can be installed on the input slider 430, and second magnets can be installed on the two second clamping parts 4221 of the second clamping structure 422 of the output slider 420. The first magnet is located between the two second magnets, and each second magnet can generate mutually repulsive magnetic forces with the first magnet.

[0047] Reference Figure 2 and Figure 6 In the specific implementation process, the buffer energy storage device 400 also includes a transmission nut 450 and a screw rod 460. The screw rod 460 is rotatably installed on the housing 410, and the transmission nut 450 is installed on the input slider 430. The transmission nut 450 and the screw rod 460 are spirally matched, and the screw rod 460 is detachably connected to the clutch device 300.

[0048] Of course, other transmission modes may also be used between the buffer energy storage device 400 and the clutch device 300. For example, the transmission mode of the screw rod 460 and the transmission nut 450 may be replaced by the transmission mode of the gear and the rack.

[0049] Reference Figure 1 and Figure 2According to some embodiments of the present invention, the drive device 200, the clutch device 300, the buffer energy storage device 400, the speed control device 500 and the load-bearing hinge 100 can be assembled and disassembled in a modular manner. Therefore, the drive device 200, the clutch device 300, the buffer energy storage device 400 and other devices are all arranged as separate modules, and each module can be assembled and disassembled, which can be convenient for installation. During the later maintenance and replacement, a certain module can be directly replaced, which is convenient for maintenance and for later structural upgrades of a certain module. In addition, the load-bearing hinge 100 can be used alone, and consumers can also add or reduce the speed control device 500, the buffer energy storage device 400, the clutch device 300 and the drive device 200 based on the load-bearing hinge 100 according to actual needs.

[0050] In the specific implementation process, in order to realize the detachability of each module, the transmission connection between two adjacent modules is detachable. Specifically, for the transmission connection for transmitting torque, such as the transmission connection between the buffer energy storage device 400 and the clutch device 300, the screw rod 460 of the buffer energy storage device 400 and the clutch sleeve 340 of the clutch device 300 can be plugged in or driven by face gears, so that the clutch sleeve 340 can drive the screw rod 460 to rotate, and the screw rod 460 and the clutch sleeve 340 can be disassembled and assembled by plugging and pulling, which is convenient for disassembly and assembly; for the transmission connection for transmitting push-pull forces, such as the buffer energy storage device 400 and the speed control device 500, the input part of the speed control device 500 can be screwed or snapped with the output part of the buffer energy storage device 400 by screwing or snapping, so that the output part of the buffer energy storage device 400 can drive the input part of the speed control device 500 to slide, and the disassembly and assembly between the output part of the buffer energy storage device 400 and the input part of the speed control device 500 can be completed by rotation, which is convenient for disassembly and assembly.

[0051] Reference Figure 1 and Figure 5According to some embodiments of the present invention, the load-bearing hinge 100 also includes a first adapter 130 and a second adapter 140, the first adapter 130 and the second adapter 140 are rotatably connected via a first rotating shaft 150, one end of the first adapter 130 is rotatably connected to the first connecting seat 110 via a second rotating shaft 160, the other end of the first adapter 130 is slidably mounted on the second connecting seat 120, and the other end of the first adapter 130 can rotate relative to the second connecting seat 120, the other end of the first adapter 130 is transmission-connected to the driving device 200, the first rotating shaft 150 is located between the second rotating shaft 160 and the other end of the first adapter 130, one end of the second adapter 140 is rotatably connected to the second connecting seat 120 via a third rotating shaft 170, the other end of the second adapter 140 is slidably mounted on the first connecting seat 110, and the other end of the second adapter 140 can rotate relative to the first connecting seat 110. Through the above-mentioned arrangement, the driving device 200 can drive the first connecting seat 110 to rotate relative to the second connecting seat 120, wherein the first connecting seat 110 and the second connecting seat 120 are rotatably connected through the cooperation of the first adapter 130 and the second adapter 140. As a result, the structural strength of the entire load-bearing hinge 100 can be higher and can withstand a greater weight. In addition, the rotation between the first connecting seat 110 and the second connecting seat 120 is more stable and smooth, thereby reducing the noise during the rotation process and achieving a silent effect.

[0052] Reference Figure 6 In order to improve the stability of the first adapter 130 when sliding relative to the second connecting seat 120, a guide portion 131 is rotatably installed on the other end of the first adapter 130, and the second connecting seat 120 is provided with a guide groove 121. The guide portion 131 can be slidably installed in the guide groove 121. Therefore, the guide portion 131 can be in surface contact with the inner wall of the guide groove 121, so that the first adapter 130 can slide relative to the second connecting seat 120 more smoothly.

[0053] It should be noted that there are various types of hinges in the technical field, and the load-bearing hinge 100 mentioned above can also refer to the structural setting of existing hinges, and the specific setting method will not be described in detail here.

[0054] Reference Figure 2 and Figure 7In some embodiments, the speed control device 500 can be configured as a hydraulic speed regulator. Specifically, the speed control device 500 includes a speed regulating seat 510 and a piston 520. The speed regulating seat 510 is detachably connected to the second connecting seat 120. A speed regulating chamber 513 and two first oil paths 511 are arranged in the speed regulating seat 510. Each first oil path 511 is connected to the speed regulating chamber 513 through two connecting ports 512. The two connecting ports 512 of one first oil path 511 are close to the middle of the speed regulating chamber 513. The two connecting ports 512 of the other first oil path 511 are close to the two ends of the speed regulating chamber 513 in a one-to-one correspondence. The piston 520 is slidably installed in the speed regulating chamber 513. One end of the piston 520 is connected to the first transmission rod 530. The other end of the piston 520 is connected to the second transmission rod 540. The first transmission rod 530 is transmission-connected to the first connecting seat 110. The buffer energy storage device 400 is transmission-connected to the second transmission rod 540. Therefore, the speed regulating chamber 513 and the first oil circuit 511 can be filled with hydraulic oil. During the axial sliding of the piston 520 along the speed regulating chamber 513, the hydraulic oil on one side of the piston 520 flows to the other side of the piston 520 through the first oil circuit 511. When the piston 520 is close to the middle of the speed regulating chamber 513, there are more first oil circuits 511 for the flow of hydraulic oil, which makes the sliding resistance of the piston 520 small. When the piston 520 is close to the end of the speed regulating chamber 513, there are fewer first oil circuits 511 for the flow of hydraulic oil, which makes the sliding resistance of the piston 520 large. Therefore, through the speed control device 500, the relative rotation speed of the first connecting seat 110 and the second connecting seat 120 is small in the initial position, large in the middle position, and small in the final position, thereby avoiding the situation where the speed of the doors and windows is too high at the maximum opening angle position and the closed position, which can reduce the impact on the doors and windows when they collide with other objects, and at the same time, reduce the occurrence of collision accidents during the opening and closing of the doors and windows. The provision of the buffer energy storage device 400 can reduce the impact of the speed control device 500 on the drive device 200 during the process of controlling the speed change, thereby preventing the speed control device 500 from causing an overload on the drive device 200.

[0055] Reference 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 regulating chamber 513, the first oil circuit 511 is arranged along the axial direction of the speed regulating chamber 513, and the second connecting seat 120 is provided with an avoidance hole corresponding to the first oil circuit 511, and the first oil circuit 511 is screwed with a speed regulating bolt 550, and one end of the speed regulating bolt 550 extends to the connecting port 512 of the first oil circuit 511 close to the second connecting seat 120. Therefore, after the first connecting seat 110 and the second connecting seat 120 are relatively rotated and opened, the speed regulating bolt 550 can be operated from the avoidance hole to adjust the size of the effective connecting area between the first oil circuit 511 and the speed regulating chamber 513, thereby controlling the flow rate of the hydraulic oil in the first oil circuit 511, changing the sliding resistance of the piston 520 in the speed regulating chamber 513, and finally realizing the adjustment of 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, a second oil circuit 521 is provided in the piston 520, and a one-way valve is provided in the second oil circuit 521. When the first connection seat 110 and the second connection seat 120 rotate relative to each other to open the door and window, the one-way valve opens the second oil circuit 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 circuit 521, thereby reducing the resistance caused by the speed control device 500, making it easier to open the door and window. When the first connection seat 110 and the second connection seat 120 rotate relative to each other to close the door and window, the one-way valve closes the second oil circuit 521 to prevent the second oil circuit 521 from affecting the operation of the speed control device 500.

[0057] In the specific implementation process, a reset spring can be installed between the piston 520 and the speed regulating seat 510, and the reset spring drives the piston 520 to reset, thereby realizing automatic closing of the doors and windows. Therefore, the speed control device 500 can also have certain buffering and self-closing functions.

[0058] It is conceivable that the above-mentioned speed control device 500 can also be set in other ways. For example, the speed control device 500 can be set in a purely mechanical form. Specifically, damping blocks are provided on both sides of the speed regulating chamber 513 along the radial direction. The damping blocks are provided with V-shaped grooves. The piston 520 is located in the V-shaped grooves. The damping blocks are slidably installed on the speed regulating seat 510, and a reset structure is provided between the damping block and the speed regulating seat 510. The reset structure can be a magnetic reset structure or an elastic reset member. Therefore, when the piston 520 slides to the vicinity of the end of the speed regulating chamber 513, the piston 520 pushes the damping block to slide a large distance, and the resistance encountered by 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 piston 520 pushes the damping block to slide a small distance, and the damping encountered by the piston 520 is also small. Therefore, through the speed control device 500, the relative rotation 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 final position. The damping force applied to the piston 520 can be adjusted by adjusting the force of the reset structure on the damping block.

[0059] It should be noted that, in some other embodiments, the above-mentioned speed control device 500 may also be installed on the first connecting seat 110 . In this case, the speed control device 500 does not need to be transmission-connected to the buffer energy storage device 400 .

[0060] According to the second aspect of the present invention, the automatic system for doors or windows includes the above-mentioned automatic opening and closing rotating connection mechanism. By adopting 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, and the integrated design of the hinge and the door opening mechanism can be realized, thereby reducing the installation space requirement.

[0061] Reference Figure 8 In some embodiments, the automatic system further includes a fixed frame 600, one of the first connection seat 110 and the second connection seat 120 is fixedly mounted on the fixed frame 600, and the other is fixedly connected to a window or door body 700. When the driving device 200 drives the first connection seat 110 and the second connection seat 120 to rotate relative to each other, the window or 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 stored in the door body 700 or the window body, so that the installation space required for 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 to avoid the driving device 200 being exposed to the outside. On the one hand, it can protect the driving device 200 and other devices, reduce maintenance, and increase the service life. On the other hand, it ensures the overall appearance of the door or window and enhances the sense of technology.

[0062] In a specific implementation process, the above-mentioned fixing frame 600 can be a frame of a vehicle, or a wall or door frame at a door or window of a building.

[0063] In the specific implementation process, the driving device 200 is equipped with a control device, and the control device can be electrically connected to the rotation angle detection element. The control device detects the rotation angle of the first connection seat 110 relative to the second connection seat 120 through the rotation angle detection element. In order to realize automatic opening and closing of doors and windows, the control device has built-in AI, and the opening angle and closing angle of the doors and windows are memorized by AI. The circuit board of the control device can be partially set in the shell of the driving device 200. Of course, the control device can also be set in other places, and then the control device is connected to the driving device 200 through signals. The control device can be configured with one or more functional modules such as a door lock module, a voice recognition module, a fingerprint recognition module, a camera module, etc. The control device controls the operation of the driving device 200 through the signals sent by these functional modules.

[0064] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
