Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a hinge and door control system. Background Technology

[0002] Intelligent, seamless door control systems offer a safe, convenient, and smart portal control experience within the overall smart home ecosystem. Currently, existing entrance doors (such as steel doors) require an electric door closer (or door opener) installed at the top of the door to achieve seamless opening and closing.

[0003] However, on the one hand, although electric door closers or openers can achieve the function of pushing and closing doors without any contact, it is difficult to precisely adjust the closing speed and force, which can easily damage the door and door frame; on the other hand, electric door closers are accessories that are separate from the door. Such electric door closer devices not only need to be purchased separately, increasing costs, but also usually need to be installed externally, affecting the overall aesthetics of the door. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing contactless door opening and closing solutions, which involve additional accessories, high costs, and negative impacts on the overall aesthetics of the door. This invention provides a hinge and door control system that can control the position of the first hinge seat relative to the second hinge seat according to actual needs, thereby achieving flexible control of the door's opening and closing status without the need for additional external accessories.

[0005] To solve the above-mentioned technical problems, this utility model discloses a hinge, comprising: a first hinge seat for connecting to a door leaf; a second hinge seat for connecting to a door frame; a hinge chain hinged between the first hinge seat and the second hinge seat; a first fixing pin disposed on the hinge chain and movably connected to the first hinge seat; a second fixing pin disposed on the hinge chain and movably connected to the second hinge seat; and a driving device disposed on the first hinge seat, the driving device being pulsatorically connected to the first fixing pin; the driving device is used to drive the first fixing pin to move relative to the first hinge seat in a first direction in a forward direction, and to drive... The hinge rotates in the forward direction to cause the first hinge seat to rotate in the forward direction relative to the second hinge seat, thereby moving the first hinge seat from a first position to a second position; or, the driving device is used to drive the first fixing pin to move in the opposite direction relative to the first hinge seat along the first direction, and to drive the hinge hinge to rotate in the opposite direction, thereby causing the first hinge seat to rotate in the opposite direction relative to the second hinge seat, thereby moving the first hinge seat from the second position to the first position; in the first position, the first hinge seat and the second hinge seat are disposed opposite each other along the first direction; in the second position, the extending direction of the first hinge seat intersects the extending direction of the second hinge seat.

[0006] Using the above technical solution, the hinge in this embodiment can drive the first fixing pin through the driving device to drive the hinge hinge to rotate in the forward direction, so that the first hinge seat rotates in the forward direction relative to the second hinge seat, changing the position of the first hinge seat, so that the first hinge seat automatically moves from the first position to the second position under the drive of the driving device, completing the door push and realizing the automatic opening of the door leaf connected to the first hinge seat.

[0007] Meanwhile, the hinge in this embodiment can also precisely control the speed and force of the hinge pushing and closing the door by precisely controlling the pushing force applied to the first fixing pin by the driving device. The first fixing pin is driven by the driving device to drive the hinge hinge to rotate in the opposite direction, so that the first hinge seat rotates in the opposite direction relative to the second hinge seat, changing the position of the first hinge seat. Under the drive of the driving device, the first hinge seat automatically moves from the second position to the first position to complete the closing of the door and realize the automatic closing of the door leaf connected to the first hinge seat.

[0008] Furthermore, on the one hand, compared with existing hydraulic hinges, the hinges of this application embodiment can achieve door opening and closing through the drive device without the operator having to manually apply external force. On the other hand, compared with existing electric door closers, the hinges of this application embodiment do not add any additional peripheral components, which not only enables traditional doors to have intelligent opening and closing functions to meet the needs of seamless entry scenarios, but also ensures the overall aesthetics of the door.

[0010] By adopting the above technical solution, in this embodiment, when the hinge is driven in reverse by the driving device, it drives the second fixing pin to brake the hydraulic device, thereby realizing that the first hinge seat automatically moves from the second position to the first position under the drive of the hydraulic device, completing the door closing and achieving automatic closing of the door leaf connected to the first hinge seat. Furthermore, this embodiment, through the coordinated operation of the driving device and the hydraulic device, provides a buffering function, reducing the impact force on the door leaf and door frame when pushing and closing the door, preventing damage to the door leaf and door frame, and extending their service life.

[0031] By adopting the above technical solution, the hinge in this application embodiment can limit the included angle α between the first hinge seat and the second hinge seat to between 30° and 90°, ensuring that the door leaf connected to the first hinge seat has a sufficient opening angle for people to pass through, while avoiding excessive space occupation due to an excessive opening angle, thus improving the practicality of the hinge.

[0034] At the same time, the controller precisely controls the pushing force applied by the hinges to precisely control the speed and force of the hinges pushing and closing the door, providing a buffer function to reduce the impact on the door leaf and frame when pushing and closing the door, avoiding damage to the door leaf and frame, and extending the service life.

[0035] Furthermore, on the one hand, compared with existing door control systems that only use hydraulic hinges, the door control system of this application embodiment does not require the user to actively push the door; it can achieve the opening and closing of the door through the controller and hinges. On the other hand, compared with existing door control systems that install electric door closers, the door control system of this application embodiment does not require the addition of external components, enabling traditional doors to have intelligent opening and closing functions, thus meeting the needs of seamless entry scenarios.

[0036] According to another specific embodiment of the present invention, a door control system is disclosed, wherein the controller is used to control the drive device to drive the door leaf to rotate forward relative to the door frame, so that the door leaf moves from the first position to the second position; or, the controller is used to control the drive device to drive the door leaf to rotate in the opposite direction relative to the door frame, so that the hydraulic device of the hinge drives the door leaf to rotate in the opposite direction relative to the door frame, so that the door leaf moves from the second position to the first position.

[0054] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0055] Figure 1 A three-dimensional gate control system is illustrated according to some embodiments of this application. Figure 1 . Figure 2 A three-dimensional gate control system is illustrated according to some embodiments of this application. Figure 2 .

[0056] like Figure 1 and Figure 2 As shown in the figure, an embodiment of this application provides a door control system 1000, including: a hinge 1100, a door leaf 1200, a door frame 1300, and a controller (not shown in the figure). The door leaf 1200 is equipped with a door lock 1210, and the controller is electrically connected to both the hinge 1100 and the door lock 1210. The door lock 1210 is adapted to the door frame 1300 so that the controller can transmit a locking command to the door lock 1210, controlling the latch (not shown in the figure) inside the door lock 1210 to extend into the door frame 1300, restricting the movement of the door leaf 1200 relative to the door frame 1300; or, the controller can transmit an unlocking command to the door lock 1210, controlling the latch (not shown in the figure) inside the door lock 1210 to retract from the door frame 1300, allowing the door leaf 1200 to move relative to the door frame 1300 under the action of an external force (such as the electric pushing force of the hinge 1100 described later).

[0057] For example, the door leaf 1200 in this embodiment is a steel door, but it is not limited thereto. In actual applications, other door leaves made of materials commonly used by those skilled in the art can also be used, such as cast aluminum doors.

[0058] The aforementioned hinge 1100 is hinged between the door leaf 1200 and the door frame 1300, enabling the controller to transmit a push command to the hinge 1100, controlling the hinge 1100 to apply a pushing force to the door leaf 1200, so that the door leaf 1200 relative to the door frame 1300 in a third direction (e.g., Figure 1 The door leaf 1200 rotates in the positive direction (as shown in the middle R direction), causing it to move from the first position (see...) Figure 2 Move to the second position (participate) Figure 1 ), push open the door 1200.

[0059] Alternatively, the controller can transmit a closing command to the hinge 1100, controlling the hinge 1100 to apply a pushing force to the door leaf 1200, so that the door leaf 1200 is in a third-order opposite direction relative to the door frame 1300 (e.g., Figure 1 Rotate (as shown in the R2 direction) to move the door 1200 from the second position to the first position and close the door 1200.

[0060] For example, such as Figure 1 As shown, the door control system 1000 in this embodiment of the application further includes a load-bearing hinge 1400 and a hydraulic hinge 1500. The controller in this embodiment of the application is a programmable logic controller (PLC controller).

[0061] Specifically, such as Figure 1 As shown, door leaf 1200 is connected to door frame 1300 via hinge 1100, load-bearing hinge 1400, and hydraulic hinge 1500, respectively. That is, hinge 1100, load-bearing hinge 1400, and hydraulic hinge 1500 are all hinged between door leaf 1200 and door frame 1300. Along the second direction (e.g.) Figure 1 (As shown in the Z-direction), load-bearing hinges 1400, hinges 1100, and hydraulic hinges 1500 are arranged alternately in a sequence. Load-bearing hinge 1400 supports the weight of the door leaf 1200, while hydraulic hinge 1500 assists the door leaf 1200 relative to the door frame 1300 in a positive third direction (e.g., ...). Figure 1 (As shown in the R1 direction) rotates to reduce the force exerted by the hinge 1100 on the door leaf 1200. It can also automatically apply a pushing force to the door leaf 1200 when the door leaf 1200 is in the open state, so that the door leaf 1200 rotates relative to the door frame 1300 in the opposite direction R2 in the third direction and automatically closes the door leaf 1200.

[0062] Therefore, the door control system 1000 of this application embodiment controls the hinge 1100 through the controller, so that when the hinge 1100 receives a push command, it automatically applies a pushing force to the door leaf 1200, so that the door leaf 1200 rotates in the forward direction relative to the door frame 1300 and pushes the door leaf 1200 open; or, when the hinge 1100 receives a close command, it automatically applies a pushing force to the door leaf 1200, so that the door leaf 1200 rotates in the reverse direction relative to the door frame 1300 and closes the door leaf 1200, thereby realizing the movement of the door leaf 1200 between the first position and the second position.

[0063] At the same time, the controller precisely controls the pushing force applied by the hinge 1100, thereby precisely controlling the speed and force of the hinge 1100 in pushing and closing the door, providing a buffer function, reducing the impact force on the door leaf 1200 and the door frame 1300 when pushing and closing the door, avoiding damage to the door leaf 1200 and the door frame 1300, and extending their service life.

[0064] Furthermore, on the one hand, compared with existing door control systems that only use hydraulic hinges, the door control system 1000 of this application embodiment does not require the user to actively push the door; it can achieve the pushing and closing of the door leaf 1200 through the controller and hinge 1100. On the other hand, compared with existing door control systems that install electric door closers, the door control system 1000 of this application embodiment does not require the addition of external components, enabling traditional doors to have intelligent pushing and closing functions, thus meeting the needs of seamless entry scenarios.

[0065] For example, this application embodiment does not limit the type and number of hinges of the door control system 1000. In the above embodiment, the door control system 1000 of this application embodiment also has a load-bearing hinge 1400 and a hydraulic hinge 1500, but it is not limited to this. In actual application, other hinges commonly used by those skilled in the art can also be used. For example, the door control system 1000 also has a load-bearing hinge 1400 and two hydraulic hinges 1500, as long as the door leaf 1200 can be rotated in the forward or reverse direction relative to the door frame 1300 under the pushing force applied by the hinge 1100 to push open or close the door leaf 1200. No more specific limitation is made here.

[0066] The specific structure of the hinge 1100 described above will be explained in detail below with reference to the accompanying drawings.

[0067] Figure 3A A three-dimensional view of the hinge 1100 provided in an embodiment of this application is shown. Figure 1 . Figure 3A A three-dimensional view of the hinge 1100 provided in an embodiment of this application is shown. Figure 2 .

[0068] refer to Figure 3A and Figure 3BThe hinge 1100 in this embodiment includes: a first hinge seat 1110, a second hinge seat 1120, and a hinge chain 1130.

[0069] The first hinge seat 1110 is connected to the door leaf 1200, and the second hinge seat 1120 is connected to the door frame 1300. The hinge 1130 is hinged between the first hinge seat 1110 and the second hinge seat 1120, allowing the first hinge seat 1110 to rotate relative to the second hinge seat 1120 in a third direction (positive R1 or negative R2), thereby causing the door leaf 1200 to rotate relative to the door frame 1300 in a third direction (positive R1 or negative R2). Along the first direction (e.g.) Figure 3A and Figure 3B As shown in the X direction), the first hinge seat 1110 and the second hinge seat 1120 are positioned opposite each other. At this time, the first hinge seat 1110 (i.e., the door leaf 1200 mentioned above) is in the first position (see...). Figure 2 and Figure 3A ).

[0070] For example, such as Figure 3A and Figure 3B As shown, the first hinge seat 1110 of this application embodiment includes a first housing 1111, and the second hinge seat 1120 includes a second housing 1121. The first housing 1111 has a first receiving cavity 1111a, in which a portion of the hinge 1130 is received. The second housing 1121 has a second receiving cavity 1121a, in which another portion of the hinge 1130 is received.

[0071] For example, such as Figure 3A and Figure 3B As shown, the first housing 1111 of this application embodiment includes a first fixing part 1111b. Along the second direction Z, the first fixing part 1111b is disposed on opposite sides of the first housing 1111. The first fixing part 1111b has a first fixing hole 1111c so that the first hinge seat 1110 is fixedly connected to the door leaf 1200 through the first fixing hole 1111c of the first fixing part 1111b. The second housing 1121 includes a second fixing part 1121b. Along the second direction Z, the second fixing part 1121b is disposed on opposite sides of the second housing 1121. The second fixing part 1121b has a second fixing hole 1121c so that the second hinge seat 1120 is fixedly connected to the door frame 1300 through the second fixing hole 1121c of the second fixing part 1121b.

[0072] Figure 4 An exploded view of the hinge 1100 provided in an embodiment of this application is shown.

[0073] refer to Figure 4The hinge 1100 in this embodiment of the application further includes: a first fixing pin 1140, a second fixing pin 1150, a driving device 1160, and a hydraulic device 1170.

[0074] The first fixing pin 1140 is connected to a part of the hinge 1130 and is connected to the first hinge seat 1110 in a movable manner along the first direction X. The second fixing pin 1150 is connected to another part of the hinge 1130 and is connected to the second hinge seat 1120 in a movable manner along the first direction X.

[0075] Specifically, such as Figure 4 As shown, the hinge 1130 includes a first link 1131, a second link 1132, a third link 1133, and a fourth link 1134. One end 1131a of the first link 1131 is hinged to the first hinge seat 1110 via a first pivot (not shown in the figure), and one end 1132a of the second link 1132 is hinged to the first hinge seat 1110 via the first pivot. Along the second direction Z, a first fixing pin 1140 is connected to the other end 1131b of the first link 1131 and the other end 1132b of the second link 1132, respectively. That is, the other ends 1131b of the first link 1131 and the other ends 1132b of the second link 1132 together form a part of the hinge 1130 and are received together with the first fixing pin 1140 in the first receiving cavity 1111a.

[0076] One end 1133a of the third link 1133 and one end 1134a of the fourth link 1134 are both hinged to the second hinge seat 1120 via a third pivot (not shown in the figure). Along the second direction Z, the second fixing pin 1150 is connected to the other ends 1133b of the third link 1133 and the fourth link 1134b, respectively. That is, the other ends 1133b of the third link 1133 and the fourth link 1134b together form another part of the hinge 1130, and are received together with the second fixing pin 1150 within the second receiving cavity 1121a. Furthermore, as... Figure 4 As shown, along the second direction Z, the first link 1131, the third link 1133, the second link 1132 and the fourth link 1134 are arranged alternately and crosswise, and are hinged to each other through the second pivot (not shown in the figure).

[0077] Therefore, when the other end 1131b of the first link 1131 and the other end 1132b of the second link 1132 are driven by an external force to move along the first positive direction X1, since the first link 1131, the second link 1132, the third link 1133 and the fourth link 1134 are hinged to each other, and the first link 1131 and the second link 1132 are both hinged to the first hinge seat 1110 through the first pivot, and the third link 1133 and the fourth link 1134 are both hinged to the second hinge seat 1120 through the third pivot, the first link 1131 and the second link 1132 can rotate relative to the third link 1133 and the fourth link 1134 along the third positive direction R1, thereby driving the first hinge seat 1110 to rotate relative to the second hinge seat 1120 along the third positive direction R1.

[0078] Furthermore, since the second hinge seat 1120 is fixedly installed on the door frame 1300, the first link 1131 and the second link 1132 can also drive the other end 1133b of the third link 1133 and the other end 1134b of the fourth link 1134 to move in the opposite direction X2 along the first direction.

[0079] Alternatively, when the other end 1133b of the third link 1133 and the other end 1134b of the fourth link 1134 are driven by an external force to move in the first direction X1, the third link 1133 and the fourth link 1134 can drive the first link 1131 and the second link 1132 to rotate relative to the third link 1133 and the fourth link 1134 in the third direction opposite to R2, thereby driving the first hinge seat 1110 to rotate relative to the second hinge seat 1120 in the third direction opposite to R2.

[0080] Furthermore, at this time, the third link 1133 and the fourth link 1134 can also drive the other end 1131b of the first link 1131 and the other end 1132b of the second link 1132 to move in the opposite direction X2 along the first direction.

[0081] For example, such as Figure 3A , Figure 3B and Figure 4As shown, the first housing 1111 also includes a top wall 1111d and a bottom wall 1111e. The top wall 1111d of the first housing 1111 has a first limiting groove 1111f, which extends along the first direction X. The bottom wall 1111e of the first housing 1111 has a second limiting groove 1111g, which extends along the first direction X. Along the second direction Z, the first limiting groove 1111f and the second limiting groove 1111g are arranged opposite to each other. One end 1141 of the first fixing pin 1140 extends into the first limiting groove 1111f and connects with it, while the other end 1142 of the first fixing pin 1140 extends into the second limiting groove 1111g and connects with it. This allows the first fixing pin 1140 to move along the first limiting groove 1111f and the second limiting groove 1111g relative to the first housing 1111 in the positive direction of the first direction (e.g., along the first limiting groove 1111f and the second limiting groove 1111g). Figure 3A , Figure 3B and Figure 4 (as shown in the X1 direction) moves, or, in the opposite direction of the first direction (as shown in the X1 direction) Figure 3A , Figure 3B and Figure 4 (Movement in the X2 direction).

[0082] Therefore, when the first hinge seat 1110 rotates relative to the second hinge seat 1120 in the third positive direction R1, the first fixing pin 1140 can move relative to the first housing 1111 in the first positive direction X1 along the first limiting groove 1111f and the second limiting groove 1111g, respectively, so as to limit the movement direction of the other end 1131b of the first connecting rod 1131 and the other end 1132b of the second connecting rod 1132 to the first positive direction X1.

[0083] Alternatively, when the first hinge seat 1110 rotates relative to the second hinge seat 1120 in the opposite direction R2, the two ends of the first fixing pin 1140 can move relative to the first housing 1111 in the opposite direction X2 along the first limiting groove 1111f and the second limiting groove 1111g, respectively, so as to limit the movement direction of the other end 1131b of the first connecting rod 1131 and the other end 1132b of the second connecting rod 1132 to the opposite direction X2 along the first direction.

[0084] For example, such as Figure 3A , Figure 3B and Figure 4As shown, the second housing 1121 also includes a top wall 1121d and a bottom wall 1121e. The top wall 1121d of the second housing 1121 is provided with a third limiting groove 1121f, which extends along the first direction X. The bottom wall 1121e of the second housing 1121 is provided with a fourth limiting groove 1121g, which extends along the first direction X. Along the second direction Z, the third limiting groove 1121f and the fourth limiting groove 1121g are arranged opposite to each other. One end 1151 of the second fixing pin 1150 extends into the third limiting groove 1121f and is connected to the third limiting groove 1121f. The other end 1152 of the second fixing pin 1150 extends into the fourth limiting groove 1121g and is connected to the fourth limiting groove 1121g, so that the second fixing pin 1150 can move relative to the second housing 1121 in the first direction X1 along the third limiting groove 1121f and the fourth limiting groove 1121g, or move in the first direction X2 in the opposite direction.

[0085] Therefore, when the first hinge seat 1110 rotates relative to the second hinge seat 1120 in the third positive direction R1, the second fixing pin 1150 can move relative to the second housing 1121 in the first direction X2 along the third limiting groove 1121f and the fourth limiting groove 1121g respectively, so as to limit the movement direction of the other end 1133b of the third link 1133 and the other end 1134b of the fourth link 1134 to the first direction X2 in the opposite direction.

[0086] Alternatively, when the first hinge seat 1110 rotates relative to the second hinge seat 1120 in the opposite direction R2, the second fixing pin 1150 can move relative to the second housing 1121 in the first direction X1 along the third limiting groove 1121f and the fourth limiting groove 1121g, respectively, so as to limit the movement direction of the other end 1133b of the third link 1133 and the other end 1134b of the fourth link 1134 to the first direction X1.

[0087] For example, such as Figure 5 As shown, the first connecting rod 1131 includes a first extension section 1131c and a first bent section 1131d, and the second connecting rod 1132 includes a second extension section 1132c and a second bent section 1132d. One end of the first extension section 1131c and one end of the second extension section 1132c are each provided with a through hole, so that both ends of the first fixing pin 1140 can pass through one end of the first extension section 1131c and one end of the second extension section 1132c respectively, and extend into the first limiting groove 1111f and the second limiting groove 1111g.

[0088] One end of the first bent section 1131d is connected to the other end of the first extension section 1131c, and one end of the second bent section 1132d is connected to the other end of the second extension section 1132c. The other ends of the first bent section 1131d and the other ends of the second bent section 1132d are provided with through holes so that the two ends of the first rotating shaft (not shown in the figure) can pass through the other ends of the first bent section 1131d and the other ends of the second bent section 1132d respectively, and be fixedly connected to the first hinge seat 1110.

[0089] Furthermore, the extension direction of the first bending segment 1131d (e.g.) Figure 5 (as shown in the E direction) and the extension direction of the first extension segment 1131c (as shown in the E direction) Figure 5 The extension directions of the second bend 1132d and the second extension 1132c intersect (as shown in the F direction). The extension direction E of the first bend 1131d is parallel to the extension direction E of the second bend 1132d. The extension direction F of the first extension 1131c is parallel to the extension direction F of the second extension 1132c.

[0090] The embodiments of this application do not specify the structure of the first link 1131 and the second link 1132. In the above embodiments, the first link 1131 and the second link 1132 are both L-shaped links, but they are not limited to this. In actual applications, other structures commonly used by those skilled in the art can also be used. For example, the first link 1131 and the second link 1132 can also be C-shaped links, etc.

[0091] For example, such as Figure 5 As shown, the third link 1133 includes a third extension section 1133c and a third bent section 1133d, and the fourth link 1134 includes a fourth extension section 1134c and a fourth bent section 1134d. One end of the third extension section 1133c and one end of the fourth extension section 1134c are both provided with through holes, so that both ends of the second fixing pin 1150 can pass through one end of the third extension section 1133c and one end of the fourth extension section 1134c respectively, and extend into the third limiting groove 1121f and the fourth limiting groove 1121g.

[0092] One end of the third bending section 1133d is connected to the other end of the third extension section 1133c, and one end of the fourth bending section 1134d is connected to the other end of the fourth extension section 1134c. Both the other ends of the third bending section 1133d and the other ends of the fourth bending section 1134d are provided with through holes so that both ends of the second rotating shaft (not shown in the figure) can pass through the other ends of the third bending section 1133d and the other ends of the fourth bending section 1134d respectively, and be fixedly connected to the second hinge seat 1120.

[0093] Furthermore, the extension direction of the third bending segment 1133d (e.g.) Figure 5 (as shown in the M direction) and the extension direction of the third extension segment 1133c (as shown in the M direction) Figure 5 (As shown in the N direction) intersects, the extension direction M of the fourth bend segment 1134d intersects with the extension direction N of the fourth extension segment 1134c, the extension direction M of the third bend segment 1133d is parallel to the extension direction M of the fourth bend segment 1134d, and the extension direction N of the third extension segment 1133c is parallel to the extension direction N of the fourth extension segment 1134c.

[0094] The embodiments of this application do not specify the structure of the third link 1133 and the fourth link 1134. In the above embodiments, the third link 1133 and the fourth link 1134 are both L-shaped links, but they are not limited to this. In actual applications, other structures commonly used by those skilled in the art can also be used. For example, the third link 1133 and the fourth link 1134 can also be C-shaped links, etc.

[0095] Continue to refer to Figure 4 In this embodiment of the application, the driving device 1160 is disposed on the first hinge seat 1110 and is pulsatorically connected to the first fixing pin 1140. In this embodiment of the application, the hydraulic device 1170 is disposed on the second hinge seat 1120 and is pulsatorically connected to the second fixing pin 1150. The driving device 1160 is capable of driving the first fixing pin 1140 to move relative to the first hinge seat 1110 in a first direction forward X1 or in a first direction reverse X2. The hydraulic device 1170 is capable of driving the second fixing pin 1150 to move relative to the second hinge seat 1120 in a first direction forward X1 or in a first direction reverse X2.

[0096] Specifically, such as Figure 4 As shown, in this embodiment of the door control system 1000, the controller is electrically connected to the drive device 1160 of the hinge 1100, so that the controller can control the drive device 1160 to drive the first fixing pin 1140 to move relative to the first limiting groove 1111f and the second limiting groove 1111g of the first hinge seat 1110 along the first positive direction X1, so that the first link 1131 and the second link 1132 can rotate relative to the third link 1133 and the fourth link 1134 along the third positive direction R1, that is, drive the hinge 1130 to rotate along the third positive direction R1, thereby driving the first hinge seat 1110 to rotate relative to the second hinge seat 1120 along the third positive direction R1, so that the first hinge seat 1110 (i.e., the door leaf 1200 mentioned above) moves from the first position (see Figure 2 and Figure 3A Move to the second position (see) Figure 1 and Figure 6B ).

[0097] For example, the hydraulic device 1170 has a spring (not shown) that is kinetically connected to a second fixing pin 1150. When the drive device 1160 drives the hinge 1130 to rotate in the third direction R1, the second fixing pin 1150 applies a force to the spring to compress the spring and store elastic potential energy.

[0098] Alternatively, those skilled in the art will understand that the hydraulic device 1170 requires external actuation (e.g., external force to release the elastic potential energy of the spring) to apply a pushing force to the hinge 1130. Therefore, the controller in this embodiment can control the drive device 1160 to drive the first fixing pin 1140 to move relative to the first hinge seat 1110 in the reverse direction X2, so that the first link 1131 and the second link 1132 can rotate relative to the third link 1133 and the fourth link 1134 in the reverse direction R2, that is, drive the hinge 1130 to rotate in the reverse direction R2, so that the second fixing pin 1150 moves relative to the second hinge seat 1120 in the forward direction X1, to... The hydraulic device 1170 is actuated, causing the elastic potential energy stored in the spring within the hydraulic device 1170 to be released. Specifically, the spring applies an elastic force to the second fixing pin 1150, driving the second fixing pin 1150 to move relative to the second hinge seat 1120 in the first positive direction X1. This, in turn, allows the hydraulic device 1170 to drive the first hinge seat 1110 to rotate relative to the second hinge seat 1120 in the third negative direction R2, causing the first hinge seat 1110 (i.e., the aforementioned door leaf 1200) to move from the second position (see...) Figure 1 Move to the first position (see) Figure 2 ).

[0099] like Figure 2 and Figure 3A As shown, in the first position, along the first direction X, the first hinge seat 1110 and the second hinge seat 1120 are arranged opposite each other, that is, the extension direction X of the door leaf 1200 coincides with the extension direction X of the door frame 1300. Figure 1 As shown, in the second position, the extending direction of the first hinge seat 1110 (i.e., the extending direction of the door leaf 1200, see...) Figure 6A and Figure 6B The direction shown in the middle O direction intersects with the extension direction of the second hinge seat 1120 (i.e., the extension direction X of the door frame 1300).

[0100] For example, such as Figure 6A and Figure 6BAs shown, in the second position, the angle between the extension direction of the first hinge seat and the extension direction of the second hinge seat is α, where the angle α represents the opening angle of the door leaf 1200 in the second position, i.e., the opening angle of the door leaf 1200, 30°≤α≤90°. However, this embodiment does not limit the angle α. In actual application, any angle between 30° and 90° can be used, such as 30°, 40°, 45°, 50°, 60°, 70°, 80°, 90°, etc.

[0101] Continue to refer to Figure 4 The driving device 1160 in this embodiment includes a transmission part 1161 and a drive motor 1162. Exemplarily, the hinge 1100 in this embodiment also includes a drive housing 1112, which has a third receiving cavity 1112a. The drive motor 1162 and a portion of the transmission part 1161 are received in the third receiving cavity 1112a, and another portion of the transmission part 1161 is received in a first receiving cavity 1111a and is connected to a first fixing pin 1140.

[0102] Specifically, such as Figure 4 As shown, the transmission part 1161 is connected to the other end 1131b of the first connecting rod 1131 and the other end 1132b of the second connecting rod 1132, respectively, and the drive motor 1162 is connected to the transmission part 1161 in a transmission connection. In this embodiment of the door control system 1000, the controller is electrically connected to the drive motor 1162 of the hinge 1100, so that the controller can control the drive motor 1162 to drive the transmission part 1161 to move in the first direction X1, and drive the two ends of the first fixing pin 1140 to move in the first direction X1 relative to the first limiting groove 1111f and the second limiting groove 1111g, thereby causing the first hinge seat 1110 (i.e., the door leaf 1200 mentioned above) to move from the first position (see Figure 2 Move to the second position (see) Figure 1 ).

[0103] Alternatively, the controller can control the drive motor 1162 to drive the transmission part 1161 to move in the reverse direction X2 along the first direction, and drive the two ends of the first fixing pin 1140 to move in the reverse direction X2 relative to the first limiting groove 1111f and the second limiting groove 1111g, so that the two ends of the second fixing pin 1150 move in the forward direction X1 relative to the third limiting groove 1121f and the fourth limiting groove 1121g, so as to actuate the hydraulic device 1170 to drive the first hinge seat 1110 (i.e., the door leaf 1200 mentioned above) from the second position (see Figure 1 Move to the first position (see) Figure 2 ).

[0104] For example, such as Figure 4As shown, the transmission unit 1161 includes a push block 1161a and a transmission rack 1161b, and the drive device 1160 also includes a transmission gear 1163. Along the first direction X, one end of the transmission rack 1161b is connected to the push block 1161a, the push block 1161a is connected to the other end 1131b of the first connecting rod 1131 and the other end 1132b of the second connecting rod 1132, and the push block 1161a is slidably connected to the first housing 1111 so that the push block 1161a can slide relative to the first housing 1111 along the first direction X.

[0105] The transmission gear 1163 meshes with the transmission rack 1161b, and the transmission gear 1163 is connected to the drive motor 1162. Thus, the controller of the door control system 1000 in this embodiment can control the drive motor 1162 to drive the transmission gear 1163 to rotate in the forward direction, and drive the transmission rack 1161b to move in the first direction X1, so that the push block 1161a moves in the first direction X1, thereby driving the two ends of the first fixing pin 1140 to move in the first direction X1 relative to the first limiting groove 1111f and the second limiting groove 1111g.

[0106] Alternatively, the controller can control the drive motor 1162 to drive the transmission gear 1163 to rotate in the opposite direction, and drive the transmission rack 1161b to move in the opposite direction X2 in the first direction, so that the push block 1161a moves in the opposite direction X2 in the first direction, thereby driving the two ends of the first fixed pin 1140 to move in the opposite direction X2 relative to the first limiting groove 1111f and the second limiting groove 1111g in the first direction.

[0107] The embodiments of this application do not specify the structure of the transmission part 1161. In actual applications, transmission structures commonly used by those skilled in the art can also be adopted, such as transmission forms through chains, lead screws, sliders, and slide rails.

[0108] The following will refer to Figure 6A and Figure 6B and combined Figure 1 , Figure 2 and Figure 4 The opening and closing processes of the door control system 1000 according to the embodiments of this application will be described in detail.

[0109] For example, the hinge 1100 in this embodiment of the application also includes a control circuit board (not shown in the figure). The control circuit board is disposed in the first hinge seat 1110 and is electrically connected to the drive device 1160 and the controller of the door control system 1000, respectively. The control circuit board is used to receive control commands (such as push door command or close door command) sent by the controller and then send control commands to the drive device 1160 (such as drive motor 1162), such as forward rotation command, reverse rotation command or locking command. Thus, the door opening and closing process of the door control system 1000 in this embodiment of the application can be realized by sending, receiving and executing relevant commands between the controller, the control circuit board and the drive device 1160.

[0110] For example, the door control system 1000 in this application embodiment also includes a power supply system. The power supply system has a power supply interface, which is electrically connected to the control circuit board and drive device 1160 of the door lock 1210 and hinge 1100 of the door leaf 1200, respectively, to supply power to the door lock 1210, the control circuit board and the drive device 1160. The power supply system 1600 in this application embodiment can be an uninterruptible power supply (UPS).

[0111] For example, the hinge 1100 in this application embodiment further includes a first sensor and a second sensor. The first sensor is connected to the control circuit board and is disposed on the first hinge seat 1110. The first sensor is used to detect whether the first hinge seat 1110 (i.e., the door leaf 1200) is in the second position. When the first sensor detects that the first hinge seat 1110 (i.e., the door leaf 1200) is in the second position, the first sensor feeds back a sensor signal to the control circuit board.

[0112] For example, the first sensor in this embodiment includes a switching circuit. When the first hinge seat 1110 (i.e., door leaf 1200) is not in the second position, the switching circuit of the first sensor is in an open-circuit state, and the first sensor feeds back an open-circuit signal to the control circuit board; when the first hinge seat 1110 (i.e., door leaf 1200) is in the second position (see...), the switching circuit of the first sensor is in an open-circuit state, and the first sensor feeds back an open-circuit signal to the control circuit board. Figure 6A and Figure 6B When the door leaf 1200 is in the open position, the switching circuit of the first sensor changes from an open state to a closed state, and the first sensor feeds back a closed signal to the control circuit board.

[0113] The second sensor is connected to the control circuit board and is located inside the drive device 1160. The second sensor is used to detect whether the drive motor 1162 of the drive device 1160 is running. When the second sensor detects that the drive motor 1162 of the drive device 1160 drives the transmission gear 1163 to rotate, the second sensor feeds back a sensor signal to the control circuit board.

[0114] For example, the second sensor in this application embodiment includes a switching circuit. When the drive motor 1162 does not drive the transmission gear 1163 to rotate, the switching circuit of the second sensor is in a closed state, and the second sensor feeds back a closed signal to the control circuit board. When the drive motor 1162 drives the transmission gear 1163 to rotate, the switching circuit of the second sensor changes from a closed state to an open state, and the second sensor feeds back an open signal to the control circuit board.

[0115] For example, the door control system 1000 of this application embodiment further includes a third sensor and a fourth sensor. The third sensor is connected to the controller and is disposed on the door frame 1300. The third sensor is used to detect the area jointly defined by the door leaf 1200 and the door frame 1300 when the door leaf 1200 moves from the second position to the first position, that is, during the closing process of the door leaf 1200 (see Figure 6A and Figure 6B Does the sector shown in the figure contain any obstacles?

[0116] For example, in this embodiment of the application, the third sensor is a microwave sensor, including a switching circuit. When the door leaf 1200 has not moved from the second position to the first position, or when the door leaf 1200 moves from the second position to the first position and there is no obstacle in the area jointly defined by the door leaf 1200 and the door frame 1300, the switching circuit of the third sensor is in a closed state, and the third sensor feeds back a closed signal to the controller. When the door leaf 1200 moves from the second position to the first position and there is an obstacle in the area jointly defined by the door leaf 1200 and the door frame 1300, the switching circuit of the third sensor is in an open state, and the third sensor feeds back an open signal to the controller.

[0117] The fourth sensor is connected to the controller and is located on the door frame 1300. The fourth sensor is used to detect whether the door leaf 1200 is in the first position. When the fourth sensor detects that the first hinge seat 1110 (i.e. the door leaf 1200) is in the first position, the fourth sensor sends a sensor signal back to the controller.

[0118] For example, the fourth sensor in this application embodiment includes a switching circuit. When the first hinge seat 1110 (i.e., door leaf 1200) is not in the first position, the switching circuit of the fourth sensor is in an open circuit state, and the fourth sensor feeds back an open circuit signal to the controller. When the first hinge seat 1110 (i.e., door leaf 1200) is in the first position, that is, when the door leaf 1200 is closed, the switching circuit of the fourth sensor changes from an open circuit state to a closed state, and the fourth sensor feeds back a closed signal to the controller.

[0119] The embodiments of this application do not specifically limit the types of the first sensor, second sensor, third sensor and fourth sensor. In actual application, other sensors commonly used by those skilled in the art can also be used. For example, the third sensor can also be radar.

[0120] The specific opening and closing procedures are as follows:

[0121] Before the door opening process, the door lock 1210 of the door control system 1000 receives the unlocking command input by the operator (such as fingerprint unlocking, face recognition, NFC unlocking, etc.), so that the door lock 1210 sends a verification signal to the controller of the door control system 1000. If the verification signal fed back by the door lock 1210 is accurate, that is, when the controller successfully verifies, the controller sends an unlocking command to the door lock 1210. After receiving the unlocking command, the built-in motor (not shown in the figure) of the door lock 1210 starts to work and drives the internal mechanism of the door lock 1210 to retract the bolt from the door frame 1300, so that the door leaf 1200 can rotate relative to the door frame 1300 in a third direction forward R1 or in a third direction reverse R2 under the action of external force (such as the electric driving force of the hinge 1100 described later), realizing the automatic opening and closing process of the hinge 1100. That is, the hinge 1100 in this embodiment enables the door control system 1000 to realize the function of seamless door opening and closing.

[0122] Exemplary, one embodiment of this application describes a specific door opening process including:

[0123] First, after the controller receives the unlocking signal from the door lock 1210, the controller sends a push-door command to the control circuit board of the hinge 1100. Then, after the control circuit board receives the push-door command, the control circuit board sends a forward rotation command to the drive motor 1162 of the drive device 1160 to control the drive motor 1162 to drive the transmission rack 1161b to move in the first direction X1. At this time, the second sensor sends an open circuit signal back to the control circuit board.

[0124] Subsequently, the transmission rack 1161b drives the push block 1161a to move in the first direction X1, and drives the two ends of the first fixing pin 1140 to move relative to the first limiting groove 1111f and the second limiting groove 1111g in the first direction X1, thereby causing the first hinge seat 1110 (i.e., the door leaf 1200 mentioned above) to move from the first position (see Figure 2 and Figure 3A Move to the second position (see) Figure 1 and Figure 6A ).

[0125] At this time, the first sensor detects that the first hinge seat 1110 (i.e., door leaf 1200) is in the second position and feeds back a sensor signal to the control circuit board. When the control circuit board receives the closing signal fed back by the first sensor, the control circuit board sends a locking command to the drive motor 1162 of the drive device 1160 to control the drive motor 1162 to stop driving the transmission rack 1161b to move in the first direction. At this time, the second sensor feeds back a closing signal to the control circuit board, and the control circuit board feeds back a door opening completion signal to the controller.

[0126] Thus, the hinge 1100 completes the automatic door opening process of the door control system 1000, the door leaf 1200 opens to a preset opening angle (e.g., included angle α), and the drive device 1160 of the hinge 1100 is in a locked state to keep the door leaf 1200 in the second position.

[0127] Exemplarily, a specific door-closing process in one embodiment of this application includes:

[0128] First, after a preset time (e.g., 3 to 5 seconds) after the controller receives the door opening completion signal from the controller, the controller sends a door closing command to the control circuit board of the hinge 1100. Then, after the control circuit board receives the door closing command, the control circuit board sends a reverse command to the drive motor 1162 of the drive device 1160 to control the drive motor 1162 to drive the transmission rack 1161b to move in the reverse direction X2 in the first direction. At this time, the second sensor sends an open circuit signal to the control circuit board.

[0129] Subsequently, the transmission rack 1161b drives the push block 1161a to move in the opposite direction X2 along the first direction, and drives the two ends of the first fixing pin 1140 to move in the opposite direction X2 relative to the first limiting groove 1111f and the second limiting groove 1111g, thereby actuating the hydraulic device 1170. At the same time, the control circuit board sends a locking command to the drive motor 1162 of the drive device 1160 to control the drive motor 1162 to stop driving the transmission rack 1161b to move in the first direction. At this time, the second sensor feeds back a closing signal to the control circuit board, and causes the hydraulic device 1170 to automatically drive the first hinge seat 1110 (i.e., the aforementioned door leaf 1200) from the second position (see Figure 1 and Figure 6A Move to the first position (see) Figure 2 and Figure 3A ).

[0130] At this time, the fourth sensor detects that the first hinge seat 1110 (i.e., door leaf 1200) is in the first position and sends a sensor signal back to the controller.

[0131] Thus, hinge 1100 completes the automatic closing process of door control system 1000, and drive device 1160 of hinge 1100 is in a locked state to keep door leaf 1200 in the first position.

[0132] Finally, after the controller receives the closing signal from the fourth sensor, the controller sends a locking command to the door lock 1210. After receiving the locking command, the built-in motor (not shown in the figure) of the door lock 1210 starts to work and drives the internal mechanism of the door lock 1210 to extend the latch into the door frame 1300, thus restricting the movement of the door leaf 1200 relative to the door frame 1300.

[0133] For example, in the door control system 1000 of this application embodiment, during the closing process, the hydraulic device 1170 of the hinge 1100 and the hydraulic system inside the hydraulic hinge 1500 act as a buffer, causing the door 1200 to close slowly, completing the first stroke of the closing process. For example, the door 1200 rotates from the second position (angle α = 90°) in the opposite direction R2 to the third position (e.g., angle α = 40°). Then, when the door 1200 continues to move from the third position to the first position (angle α = 0°), the closing speed of the door 1200 will slow down to prevent hand pinching and impact, and to prevent the door 1200 from violently hitting the door frame due to inertia, thus completing the second stroke of the closing process.

[0134] Furthermore, by way of example, the door control system 1000 of this application embodiment also has an anti-pinch obstacle avoidance function by setting a third sensor electrically connected to the controller.

[0135] One embodiment of this application includes a specific anti-pinch obstacle avoidance process:

[0136] First, after the controller receives the open circuit signal from the third sensor, it indicates that the third sensor has detected an obstacle (or people entering or exiting) in the area jointly defined by the door leaf 1200 and the door frame 1300. The controller then sends an obstacle avoidance command to the control circuit board of the hinge 1100. After receiving the obstacle avoidance command, the control circuit board sends a reverse command to the drive motor 1162 of the drive device 1160 to control the drive motor 1162 to drive the transmission rack 1161b to move in the reverse direction X2 in the first direction. At this time, the second sensor sends an open circuit signal back to the control circuit board.

[0137] Subsequently, the transmission rack 1161b drives the push block 1161a to move in the first direction X1, and drives the two ends of the first fixing pin 1140 to move relative to the first limiting groove 1111f and the second limiting groove 1111g in the first direction X1, so as to lock the hydraulic device 1170, that is, drive the door leaf 1200 to stay in the current position (e.g., included angle α=60°). At the same time, the control circuit board sends a locking command to the drive motor 1162 of the drive device 1160 to control the drive motor 1162 to stop driving the transmission rack 1161b to move in the first direction. At this time, the second sensor feeds back a closing signal to the control circuit board.

[0138] Next, after the controller receives the closing signal from the third sensor, indicating that the third sensor has detected no obstacles (or people entering or exiting) within the area jointly defined by the door leaf 1200 and the door frame 1300, the controller sends a push-door command to the control circuit board of the hinge 1100. Then, after receiving the push-door command, the control circuit board sends a forward rotation command to the drive motor 1162 of the drive device 1160, causing the first hinge seat 1110 (i.e., the aforementioned door leaf 1200) to reset and move to the second position (see...). Figure 1 and Figure 6B ).

[0139] Finally, the above-mentioned door closing process continues to be executed so that the first hinge seat 1110 (i.e. the door leaf 1200 mentioned above) moves from the second position to the first position, and the hinge 1100 completes the automatic door closing process of the door control system 1000.

[0140] In the above embodiments, the hinge 1100, through the coordinated operation of the drive device 1160 and the hydraulic device 1170, drives the hinge 1130 to rotate in a third direction (positive R1 or negative R2), thereby realizing the opening and closing of the door 1200. However, this application does not specifically limit the structure of the hinge 1100 that drives the hinge 1130 to rotate in a third direction, as long as it can drive the hinge 1130 to rotate in a third direction (positive R1 or negative R2) to realize the automatic opening and closing of the door 1200, thereby meeting the requirements of the seamless entry scenario.

[0141] In one possible implementation, the hinge 1100 of this application embodiment may not be equipped with a hydraulic device 1170. That is, compared with the above-described embodiments, the hinge 1100 of this application embodiment drives the hinge 1130 to rotate in a third direction, either forward R1 or reverse R2, solely through the drive device 1160.

[0142] That is, the opening process of this application embodiment is the same as that of the above embodiment, the difference being that: the second hinge seat 1120 of the hinge 1100 in this application embodiment is not provided with a hydraulic device 1170, and the closing process of this application embodiment is different from that of the above embodiment.

[0143] Exemplary, another embodiment of this application's specific door-closing process includes:

[0144] First, after a preset time (e.g., 3 to 5 seconds) after the controller receives the door opening completion signal from the controller, the controller sends a door closing command to the control circuit board of the hinge 1100. Then, after the control circuit board receives the door closing command, the control circuit board sends a reverse command to the drive motor 1162 of the drive device 1160 to control the drive motor 1162 to drive the transmission rack 1161b to move in the reverse direction X2 in the first direction. At this time, the second sensor sends an open circuit signal to the control circuit board.

[0145] Subsequently, the transmission rack 1161b drives the push block 1161a to move in the opposite direction X2 along the first direction, and drives the two ends of the first fixing pin 1140 to move in the opposite direction X2 relative to the first limiting groove 1111f and the second limiting groove 1111g, so as to drive the hinge 1130 to rotate in the opposite direction R2 along the third direction, so that the second fixing pin 1150 moves in the positive direction X1 relative to the second hinge seat 1120, thereby driving the first hinge seat 1110 (i.e., the door leaf 1200 mentioned above) from the second position (see Figure 1 and Figure 6A Move to the first position (see) Figure 2 and Figure 3A ).

[0146] At this time, the fourth sensor detects that the first hinge seat 1110 (i.e., door leaf 1200) is in the first position and sends a sensor signal back to the controller.

[0147] Thus, hinge 1100 completes the automatic closing process of door control system 1000, and drive device 1160 of hinge 1100 is in a locked state to keep door leaf 1200 in the first position.

[0148] Finally, after the controller receives the closing signal from the fourth sensor, the controller sends a locking command to the door lock 1210. After receiving the locking command, the built-in motor (not shown in the figure) of the door lock 1210 starts to work and drives the internal mechanism of the door lock 1210 to extend the latch into the door frame 1300, thus restricting the movement of the door leaf 1200 relative to the door frame 1300.

[0149] In summary, the door control system 1000 of this application embodiment realizes the automatic opening and closing functions of the door leaf 1200 relative to the door frame 1300 through the control cooperation between the controller and the hinge 1100. In addition, it can avoid obstacles in time under abnormal conditions (such as when the third sensor detects that there are obstacles or people entering or leaving the area jointly defined by the door leaf 1200 and the door frame 1300), thus ensuring the safety of personnel and equipment.
