[0034] Please refer to Figure 1 together. Now, the door opening and closing structure assembly provided by the present utility model will be described. The door opening and closing structure assembly includes a door shaft 10, a door body 20, an electric control lock 30, a switch driving assembly 40, and a control module 50; the door shaft 10 is rotatably connected to the ground 60; one side of the door body 20 is fixed to the door shaft 10, and the swinging side of the door body 20 has a lock hole 201; the electric control lock 30 has a lock pin 310 that can be inserted and adapted to the lock hole 201; the switch driving assembly 40 is arranged below the ground 60, and the switch driving assembly 40 includes a switch driver 410, a first transmission mechanism 420, and a second transmission mechanism 430. The output shaft of the switch driver 410 is connected to the input end of the first transmission mechanism 420, the output end of the first transmission mechanism 420 is connected to the input end of the second transmission mechanism 430, and the output end of the second transmission mechanism 430 is connected to the lower end of the door shaft 10; the control module 50 is respectively communicatively connected to the electric control lock 30 and the switch driver 410. The control module 50 is used to collect door opening instructions and door closing instructions to control the electric control lock 30 to unlock or lock, and also controls the switch driver 410 to drive the door shaft 10 to rotate.

[0035] In this embodiment, the control module 50 has a door opening trigger key 510 and a door closing trigger key 520 (as Figure 1 shown), and the door can be opened and closed by touching the door opening trigger key 510 or the door closing trigger key 520 with body parts such as elbows, knees, feet, etc., so as to avoid directly opening and closing the door with hands; it should be understood that according to the different body touch parts, the setting height of the control module 50 is different. For example, when set at a position close to the ground 60, it is suitable for foot touch, and when set at a position about 1.2 m away from the ground 60, it is suitable for elbow touch (as Figure 1 shown). Or, the control module 50 is integrated with a voice module, and the user can open and close the door by voice control. For example, when the user says the voice command "open the door", the voice module will generate an open door command after collecting the voice signal, and then the door can be opened.

[0036] In this embodiment, the communication connection between the control module 50 and the electric control lock 30 and the switch driver 410 can be achieved by means of a wired connection or a wireless connection (such as Bluetooth, wifi).

[0037] Compared with the prior art, in the closed state of the door-opening and -closing structure assembly provided in this embodiment, the locking pin 310 of the electric control lock 30 is inserted into the lock hole 201; if the door needs to be opened, an opening command (such as a touch command or a voice control command) is sent to the control unit, and the locking pin 310 of the electric control lock 30 is retracted according to the opening command to release the locked state. Subsequently, the control unit controls the switch driver 410 to start, and drives the door shaft 10 to rotate through the first transmission mechanism 420 and the second transmission mechanism 430. The door body 20 rotates synchronously with the door shaft 10, and finally the door-opening operation is realized; if the door needs to be closed, a closing command (such as a touch command or a voice control command) is sent to the control unit, and the switch driver 410 is controlled to start according to the closing command. The door shaft 10 is driven to rotate through the first transmission mechanism 420 and the second transmission mechanism 430, and the door body 20 rotates synchronously with the door shaft 10 to close. Subsequently, the control unit controls the locking pin 310 of the electric control lock 30 to extend, and returns from the unlocked state to the locked state again, and finally the door-closing operation is realized. The door-opening and -closing structure assembly of this embodiment cancels the design of the door handle, and outputs an opening command or a closing command to the control module 50 by means of voice control, touch, etc., so as to realize the door-opening and -closing operation without manual operation, and avoid the problem that the hand is contaminated and finally affects the indoor cleanliness.

[0038] In some embodiments, the above-mentioned first transmission mechanism 420 may adopt such as Figure 1 , Figure 2 and Figure 6In the shown structure, the first transmission mechanism 420 includes a first transmission wheel 421, a second transmission wheel 422, and a flexible transmission member 423. The output shaft of the switch driver 410 is coaxially connected to the first transmission wheel 421. The flexible transmission member 423 is wound around the first transmission wheel 421 and the second transmission wheel 422, and the second transmission wheel 422 is connected to the input end of the second transmission mechanism 430. The first transmission mechanism 420 of this embodiment adopts a flexible transmission method, which has the following beneficial effects: First, it can absorb vibration loads and the effects of damping vibration, so the transmission is stable. It is often used for transmissions in cases with a relatively large center distance, simplifies the structure, and reduces costs; Second, due to the elastic action of the flexible element, it can buffer and absorb vibration, resulting in lower noise during operation; Third, the structure of the flexible transmission is relatively simple, with low requirements for manufacturing and installation accuracy, and low costs; Fourth, the elastic characteristics of the flexible element enable it to play a role in buffering and damping vibration during operation, protecting other transmission components from damage; Fifth, in case of overload, the flexible element will slip on the pulley, thereby protecting other transmission components from damage; Sixth, the flexible transmission is particularly suitable for transmission systems with a relatively large center distance, can effectively transmit power, and is more convenient for installation and adjustment.

[0039] During specific implementation, the specific implementation methods of the flexible transmission member 423 include but are not limited to transmission belts (the first transmission wheel 421 and the second transmission wheel 422 correspond to pulley wheels), transmission chains (the first transmission wheel 421 and the second transmission wheel 422 correspond to sprocket wheels), etc., which will not be listed one by one here.

[0040] Based on the above embodiment, refer to Figure 1 、 Figure 2 and Figure 6 ,the second transmission mechanism 430 includes a first driving gear 431 and a second driving gear 432. The first driving gear 431 is coaxially connected to the second transmission wheel 422, the second driving gear 432 is coaxially connected to the door shaft 10, and the first driving gear 431 meshes with the second driving gear 432. The first transmission mechanism 420 of this embodiment adopts a gear transmission method, which has the following beneficial effects: First, gear transmission can ensure an accurate transmission ratio, can achieve a constant instantaneous transmission ratio, and can precisely control the rotational speed and direction; Second, the power range that gear transmission can transmit is extremely wide, applicable from extremely low power to extremely high power, and its circumferential speed range is also very wide, and it can adapt to different working conditions; Third, the efficiency of gear transmission is very high, with less energy loss, and can effectively convert and transmit power; Fourth, the structure of gear transmission is relatively compact, and can achieve high-efficiency power transmission within a limited space; Fifth, gear transmission has a long working life and high reliability, and can maintain stable performance in various working environments.

[0041] In some specific embodiments, the first driving gear 431 and the second driving gear 432 are both spur gears. Since the door shaft 10 extends vertically, the rotation axes of the first driving gear 431, the second driving gear 432, the first transmission wheel 421 and the second transmission wheel 422 are parallel to the up-down direction, and the output axis of the locking driver 330 is also parallel to the up-down direction. Figure 1 and Figure 6 In other embodiments, the first driving gear 431 and the second driving gear 432 are both bevel gears, the rotation axis of the second driving gear 432 is parallel to the up-down direction, the rotation axes of the first driving gear 431, the first transmission wheel 421 and the second transmission wheel 422 are perpendicular to the up-down direction, and the output shaft of the locking driver 330 is also perpendicular to the up-down direction, such as Figure 2 shown.

[0042] In some embodiments, in order to realize the connection between the main door body, the door shaft 10 and the wall, see Figure 1 The door opening and closing structure assembly further includes a door frame 70, a door body 20 is disposed inside the door frame 70, and a door shaft 10 is rotatably connected to the door frame 70; an accommodation space 701 is disposed inside the door frame 70, a main lock body of the electric control lock 30 is disposed inside the accommodation space 701, and a lock pin 310 is connected to the main lock body and can extend or retract into the accommodation space 701. In this embodiment, the door frame 70, the door shaft 10 and the main door body can be connected to the wall after forming an integral structure, so as to realize a modular installation method, which is more convenient to install.

[0043] More specifically, the extended end of the lock pin 310 is provided with a guide slope 311 to facilitate the lock pin 310 to be inserted into the lock hole 201. Figures 3 to 5 shown.

[0044] In some embodiments, see Figures 3 to 5 , a rack 312 extending along its own axial direction is provided on the outer peripheral surface of the lock pin 310; the main lock body of the electric control lock 30 includes a shell 320, and also includes a locking driver 330 and a locking driving gear 340 arranged in the shell 320, the lock pin 310 is inserted in the shell 320 along its own axial direction, the shell 320 is fixed in the accommodating space 701, the locking driving gear 340 is rotatably connected to the shell 320, and the locking driving gear 340 is meshed with the rack 312, the locking driver 330 is transmission-connected with the locking driving gear 340, and the locking driver 330 is also communication-connected with the control module 50. In this embodiment, the telescopic drive of the lock pin 310 is realized by gear transmission, and the telescopic action of the lock pin 310 is more stable. The implementation method of the locking driver 330 of this embodiment includes but is not limited to a stepping motor, a servo motor, etc.

[0045] Based on the above embodiments, see Figures 3 to 5, a limiting groove 313 extending along the axial direction of the locking pin 310 is provided on the outer peripheral surface of the locking pin 310. A limiting member 321 is fixed inside the housing 320. The free end of the limiting member 321 extends into the limiting groove 313 and can selectively contact two groove end faces of the limiting groove 313 to limit the telescopic stroke of the locking pin 310, avoid the locking pin 310 from being inserted too deep into the lock hole 201, and also avoid the locking pin 310 from retracting excessively into the housing 320, resulting in the problem of gear connection failure.

[0046] In some embodiments, referring to Figures 3 to 5 , the width of the limiting member 321 gradually decreases in the direction close to the locking pin 310, and the end of the limiting member 321 far from the locking pin 310 is strengthened to avoid the limiting member 321 from breaking.

[0047] In some specific embodiments of the locking drive gear 340, referring to Figures 3 to 5 , the locking drive gear 340 is a half gear, which has a meshing section 341 and an idling section 342. The meshing section 341 can mesh with the rack 312, and the idling section 342 is separated from the rack 312. The main lock body further includes an elastic member 350. The elastic member 350 is arranged between the insertion end of the locking pin 310 and the housing 320. When the idling section 342 corresponds to the rack 312, the elastic member 350 pushes the locking pin 310 to extend out of the housing 320. When the idling section 342 corresponds to the rack 312, the extension action of the locking pin 310 is supported by the elastic member 350 to avoid the retraction of the locking pin 310 and ensure the reliability of locking. When unlocking is required, the locking drive gear 340 rotates to make the meshing section 341 gradually approach the rack 312, and pushes the locking pin 310 to retract during the meshing with the rack 312. While the locking pin 310 retracts, it compresses the elastic member 350 to store energy for the next locking. This embodiment realizes the switching between the locked state and the unlocked state through the combination of gear transmission and elastic drive. In the locked state, the locking drive 330 does not need to provide a locking support force, and the use reliability is better.

[0048] In some embodiments, for the convenience of installation with good elasticity, referring to Figures 3 to 5 , a guiding support 351 is provided inside the housing 320. One end of the guiding rod 380 is fixed to the guiding support 351. One end of the elastic member 350 contacts the guiding support 351, and the other end contacts the insertion end of the locking pin 310. More specifically, both ends of the elastic member 350 are respectively connected to the guiding support 351 and the locking pin 310 through hanging or other means; or one end of the elastic member 350 is connected to the guiding support 351 through hanging or other means, and the other end is connected with a contact gasket 352, and the contact gasket 352 can be in abutting contact with the insertion end face of the locking pin 310 (as Figure 5 shown); or one end of the elastic member 350 abuts against the guiding support 351, and the other end is connected with a contact gasket 352, and the contact gasket 352 can be in abutting contact with the insertion end face of the locking pin 310.

[0049] In some embodiments, in order to realize the transmission connection between the locking driver 330 and the locking drive gear 340, see Figures 3 to 5 A worm 360 is coaxially connected to the output shaft of the locking driver 330 , and a worm wheel 370 is coaxially fixed to the locking driving gear 340 , and the worm wheel 370 and the worm 360 are meshed with each other.

[0050] This embodiment adopts the transmission method of worm wheel 370 and worm 360, which can withstand large loads and has a high load-bearing capacity. In addition, compared with other transmission methods, the worm wheel 370 and worm 360 transmission can achieve a larger transmission ratio, and its structural design is compact, which is suitable for application scenarios with limited space. Moreover, the friction noise of the worm wheel 370 and worm 360 transmission is small, which can ensure the accuracy and smoothness of the transmission and reduce vibration and impact. Moreover, in some specific applications, the worm wheel 370 and worm 360 transmission has a self-locking function, which increases safety. Due to the use of meshing transmission, the friction noise is relatively small.

[0051] In some embodiments, see Figures 3 to 5 The insertion end of the lock pin 310 is provided with a guide hole 314 extending along its own axial direction, and a guide rod 380 is fixed in the housing 320 and is slidably plugged into the guide hole 314. The elastic member 350 is sleeved on the outer circumference of the guide rod 380. When the lock pin 310 is telescopically moved, the guide rod 380 is always inserted in the guide hole 314, thereby limiting the displacement of the lock pin 310 itself on the telescopic path of the lock pin 310; at the same time, since the elastic member 350 is sleeved on the outer circumference of the guide rod 380, the guide rod 380 can also limit the displacement of the elastic member 350 in the radial direction of the guide rod 380, thereby preventing the elastic member 350 from being deflected. Among them, the specific implementation of the elastic member 350 includes but is not limited to a spring, a rubber sleeve, etc., which can meet the assembly and use requirements.

[0052] In some embodiments, in order to provide installation space for the switch drive assembly 40 without affecting the user's stepping, see Figure 1 , Figure 2 and Figure 6 An installation groove 601 is opened on the ground 60, and the switch driver 410, the first transmission mechanism 420 and the second transmission mechanism 430 are all placed in the installation groove 601; the switch door structure assembly also includes a sealing pedal 80, which is covered at the top opening of the installation groove 601, and the door shaft 10 passes through the sealing pedal 80.

[0053] In some specific embodiments, see Figure 6, in order to fix the first transmission mechanism 420, the second transmission mechanism 430 and the switch driver 410 in the installation sink 601, the switch door structure assembly further includes a drive installation bracket 90 disposed in the installation sink 601. The drive installation bracket 90 includes a horizontal bracket 910 in a grid shape and also includes a vertical bracket 920; the horizontal bracket 910 is formed by the intersection of a plurality of cross bars and a plurality of longitudinal bars, and the cross bars and the longitudinal bars are fixedly welded, and the two ends of the cross bars and the two ends of the longitudinal bars are respectively embedded in the side walls of the installation sink 601 to realize the overall fixation of the horizontal bracket 910; the vertical bracket 920 penetrates through the grid of the horizontal bracket 910 up and down and is tied and fixed to the adjacent cross bar or longitudinal bar, the lower end of the vertical bracket 920 is supported on the bottom surface of the installation sink 601, and the upper end is supported on components such as the second drive gear 432 and the second transmission wheel 422 that need to be supported; in addition, the switch driver 410 is placed on the horizontal bracket 910 and can be fixed to the horizontal bracket 910 by welding, tying, etc.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
