[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4 As shown, an embodiment of the present invention provides a child-proof anti-accidental touch structure for a smart door lock, including a rear panel 1; a handle 11 rotatably connected to the side wall of the rear panel 1; a locking component provided on the side wall of the rear panel 1; a quick-unlocking component provided on the rear panel 1 via the locking component; a buffer component provided on the rear panel 1 via the locking component; a sweat-absorbing component provided on the top of the handle 11; and an anti-slip component provided on the top of the handle 11. During operation, the rear panel 1 and handle 11 are installed indoors. When the child-proof anti-accidental touch function needs to be activated, the locking component is opened, limiting the handle 11 and preventing it from turning downwards, thus preventing accidental opening of the door by a child. When the locking component is closed, the handle 11 can be freely... When rotated downwards, the quick-unlock component can quickly release the limiting function of handle 11. When handle 11 is limited, it rotates downwards and collides with the locking component. The buffer component cushions the impact of the handle 11. When the hand grips handle 11, the sweat-absorbing component absorbs the sweat from the hand, and the anti-slip component increases the friction between the hand and handle 11. Through the above structure, the locking component limits the handle 11, forming a child-proof anti-accidental-touch structure for the smart door lock. This achieves the function of locking and limiting handle 11, solving the problem of children accidentally touching handle 11 and causing the door to be accidentally opened, improving the safety of using the smart door lock, and reducing the safety hazards caused by the door being accidentally opened.

[0025] like Figures 1 to 3As shown, the locking assembly includes a fixed rod 12, a fixed frame 13, a servo motor 14, a lead screw 15, a sliding block 16, and a stop 17. The fixed rod 12 is fixedly connected to the side wall of the handle 11 away from the rear panel 1. The fixed frame 13 is fixedly connected to the side wall of the rear panel 1 near the fixed rod 12. The servo motor 14 is fixedly connected to the end of the fixed frame 13 near the rear panel 1. The lead screw 15 is fixedly connected to the transmission end of the servo motor 14. The sliding block 16 cooperates with the lead screw 15 and the lead screw nut pair. The stop 17 is slidably connected to the outer wall of the sliding block 16. The stop 17 is engaged with the outer wall of the sliding block 16 by a quick unlocking assembly. A support assembly is provided at the bottom of the fixed frame 13. During operation, when the locking assembly is opened, the servo motor 14 is started, and the servo motor 14 drives the lead screw 15 to rotate. The lead screw 15 drives the sliding block 16 and the stop 17 to rotate in the fixed frame 13. 3. Internal sliding pushes the stop 17 out of the fixing frame 13, blocking the fixing rod 12. When the locking assembly is closed, the reverse servo motor 14 drives the lead screw 15 to reverse, thereby driving the sliding block 16 and the stop 17 closer to the rear panel 1, retracting the stop 17 into the fixing frame 13, and releasing the restriction of the stop 17 on the fixing rod 12. Through the above structure, the servo motor 14 drives the stop 17 to extend into the fixing frame 13 and block the handle 11, forming a locking and limiting structure for the handle 11. This realizes the function of limiting the downward rotation of the handle 11, solving the problem of children accidentally touching the handle 11 and opening the door lock, reducing the situation where children accidentally touch the handle 11 and the door is opened, reducing the safety hazards caused by accidentally opening the door, and improving the convenience of limiting and releasing the handle 11.

[0026] like Figure 2 and Figure 3As shown, the quick-unlocking assembly includes a slide groove 2, a sliding rod 21, a locking block 22, a first spring 23, a positioning groove 24, and a lifting block 25. The slide groove 2 is located on the top of the fixing frame 13 away from the servo motor 14. The sliding rod 21 is slidably connected to the middle of the stop block 17. The positioning groove 24 is located on the top of the sliding block 16 near the slide groove 2. A pair of positioning grooves 24 are provided on the top of the sliding block 16 and are symmetrically arranged. The locking block 22 is fixedly connected to the bottom end of the sliding rod 21. The first spring 23 is sleeved on the outer wall of the sliding rod 21 near the locking block 22. The end of the first spring 23 away from the locking block 22 is fixedly connected to the inside of the stop block 17. The lifting block 25 is fixedly connected to the top end of the sliding rod 21. During operation, when the stop block 17 extends, the sliding rod 21 presses the locking block 22 into the servo motor 14 under the elastic force of the first spring 23. The sliding rod 21 fixes the stop block 17 to the outer wall of the sliding block 16. When the servo motor 14 loses power and cannot work, the locking state of the handle 11 needs to be released. Pulling the lifting block 25 causes the sliding rod 21 and the locking block 22 to move upwards, compressing the first spring 23 and disengaging the locking block 22 from the positioning groove 24. Sliding the stop block 17 pushes it into the fixing frame 13, releasing the lifting block 25. The first spring 23 then causes the sliding rod 21 and the locking block 22 to move downwards, inserting the locking block 22 into another set of positioning grooves 24 within the stop block 17. This fixes the stop block 17 to the outer wall of the sliding block 16 near the rear panel 1, achieving the function of quickly releasing the locking state of the handle 11. Through the above structure, the arrangement of lifting the lifting block 25 and sliding the stop block 17 near the servo motor 14 forms a structure for quickly releasing the locking state of the handle 11, achieving the function of quickly releasing the locking state of the handle 11. This solves the problem of the stop block 17 being unable to retract into the fixing frame 13 due to a power outage of the servo motor 14, increases the physical release function of the stop block 17's locking state, and reduces the situation where the handle 11 cannot be released due to a power outage.

[0027] like Figure 4As shown, the buffer assembly includes a push rod 3, a silicone plate 31, and a second spring 32; the push rod 3 is slidably connected to the bottom of the fixed rod 12 away from the handle 11; multiple sets of push rods 3 are provided at the bottom of the fixed rod 12; the silicone plate 31 is fixedly connected to the bottom end of the multiple sets of push rods 3; the second spring 32 is fixedly connected to the top end of the push rod 3; the other end of the second spring 32 is fixedly connected to the inside of the fixed rod 12; a dustproof component is provided on the silicone plate 31 near the top of the push rod 3; during operation, when the stop block 17 extends, the stop block 17 contacts the fixed rod 12; when the handle 11 is rotated, the fixed rod 12 contacts the stop block 12. When the top of the stop block 17 collides, the silicone plate 31 contacts the top of the stop block 17. The silicone plate 31 drives the push rod 3 to move closer to the fixed rod 12 and compress the second spring 32. The second spring 32 buffers the impact on the fixed rod 12. Through the above structure, the second spring 32 buffers the impact between the fixed rod 12 and the stop block 17, forming a buffer structure for the fixed rod 12. This achieves the function of buffering when the fixed rod 12 contacts the stop block 17, reducing the damage caused by the collision between the fixed rod 12 and the stop block 17, and improving the service life of the parts.

[0028] like Figure 4 As shown, the dustproof component includes a rubber ring 4; the rubber ring 4 is fixedly connected to the top of the silicone plate 31 near the second spring 32; the top of the rubber ring 4 is fixedly connected to the bottom of the fixing rod 12 near the top rod 3; during operation, when the silicone plate 31 is squeezed towards the fixing rod 12, the rubber ring 4 seals the gap between the silicone plate 31 and the fixing rod 12, blocking external dust or foreign objects; through the above structure, the rubber ring 4 seals the gap between the silicone plate 31 and the fixing rod 12, forming a sealing structure between the silicone plate 31 and the fixing rod 12, reducing the entry of dust or foreign objects between the silicone plate 31 and the fixing rod 12, and reducing abnormal wear of the top rod 3.

[0029] like Figure 4 As shown, the sweat-absorbing component includes absorbent cotton 5; the bottom of absorbent cotton 5 is provided with adhesive; absorbent cotton 5 is attached to the top of handle 11 with adhesive; during operation, when the hand holds handle 11, absorbent cotton 5 absorbs the sweat from the hand, and absorbent cotton 5 is replaced from time to time to keep the surface of handle 11 dry; through the above structure, the absorbent cotton 5 is set to absorb the sweat from the hand, forming a sweat-absorbing structure for handle 11, reducing the slippage caused by excessive hand sweat when holding handle 11.

[0030] like Figure 4As shown, the anti-slip component includes anti-slip protrusions 6; the anti-slip protrusions 6 are fixedly connected to the top of the handle 11 near the absorbent cotton 5; multiple sets of anti-slip protrusions 6 are provided on the top of the handle 11 and are evenly distributed on the top of the handle 11; during operation, when the hand contacts the handle 11, the anti-slip protrusions 6 increase the friction between the handle 11 and the hand; through the above structure, the anti-slip protrusions 6 increase the friction between the hand and the handle 11, reducing the slippage when holding the handle 11.

[0031] like Figure 1 As shown, the support assembly includes a reinforcing rib 7; the reinforcing rib 7 is fixedly connected to the bottom of the mounting bracket 13; the side wall of the reinforcing rib 7 is fixedly connected to the side wall of the rear panel 1 near the mounting bracket 13; during operation, the reinforcing rib 7 supports and fixes the mounting bracket 13, improves the stability of the mounting bracket 13 when it is fixed to the side wall of the rear panel 1, and reduces the possibility of the mounting bracket 13 falling off due to the pressure of the handle 11.

[0032] When in operation, the rear panel 1 and handle 11 are installed indoors. When the child-proof function needs to be activated, the locking assembly is opened, limiting the handle 11 and preventing it from turning downwards, thus preventing accidental opening of the door by a child. When the locking assembly is closed, the handle 11 can turn downwards freely. The quick-unlock assembly quickly releases the limiting function of the handle 11. When the handle 11 is limited, it turns downwards and collides with the locking assembly; the buffer assembly cushions the impact. When the hand grips the handle 11, the sweat-absorbing assembly absorbs sweat, and the anti-slip assembly increases the friction between the hand and the handle 11. When the locking assembly is opened, the servo motor 14 is activated, driving the lead screw 15 to rotate. Rod 15 drives sliding block 16 and stop block 17 to slide inside the fixed frame 13, pushing stop block 17 out of the fixed frame 13. Stop block 17 blocks the fixed rod 12. When the locking assembly is closed, reverse servo motor 14 reverses, driving lead screw 15 to reverse, thereby moving sliding block 16 and stop block 17 closer to the rear panel 1, retracting stop block 17 into the fixed frame 13, and releasing the restriction of stop block 17 on the fixed rod 12. When stop block 17 extends, sliding rod 21, under the elastic force of the first spring 23, presses the locking block 22 into the servo motor 14. Sliding rod 21 fixes stop block 17 to the outer wall of sliding block 16. When the servo motor 14 loses power and cannot work, it is necessary to release the locking state of handle 11 and lift the lifting block 2. 5. The lifting block 25 drives the sliding rod 21 and the locking block 22 to move upward, the first spring 23 is compressed, causing the locking block 22 to disengage from the positioning groove 24, the sliding stop 17 is pushed into the fixing frame 13, the lifting block 25 is released, the first spring 23 drives the sliding rod 21 and the locking block 22 downward, inserting the locking block 22 into another set of positioning grooves 24 in the stop 17, fixing the stop 17 to the outer side wall of the sliding block 16 near the rear panel 1, realizing the function of quickly releasing the locking state of the handle 11; when the stop 17 is extended, the stop 17 contacts the fixing rod 12, when the handle 11 is rotated, the fixing rod 12 collides with the top of the stop 17, the silicone plate 31 contacts the top of the stop 17, the silicone plate 31 drives the push rod 3 towards the fixing rod 12 The second spring 32 is compressed and close to the fixed rod 12, which cushions the impact. When the silicone plate 31 is squeezed close to the fixed rod 12, the rubber ring 4 seals the gap between the silicone plate 31 and the fixed rod 12, blocking external dust or foreign objects. When the hand holds the handle 11, the absorbent cotton 5 absorbs the sweat of the hand. The absorbent cotton 5 is replaced from time to time to keep the surface of the handle 11 dry. When the hand contacts the handle 11, the anti-slip protrusions 6 increase the friction between the handle 11 and the hand. The reinforcing rib 7 supports and fixes the fixing frame 13, improves the stability of the fixing frame 13 when it is fixed to the side wall of the rear panel 1, and reduces the situation where the fixing frame 13 will fall off due to the pressure of the handle 11.
