[0047] Currently, when the elevator fails or is stalled due to power interruption in a non-level area, passengers in the car may try to open the car door on their own to seek an escape path out of panic. In this case, the passengers often cannot accurately determine the specific position of the car, and there may be a certain height difference between the car and the floor plane. Therefore, even if the passengers can successfully leave the car, they may be injured due to this height difference.

[0048] Based on this, the embodiment provides a door protection device, as shown in the drawings Figures 1-10 The door protection device comprises a lock hook assembly 3 and a lock hook seat 4, the lock hook assembly 3 is arranged on the door machine bottom plate 1, and the lock hook seat 4 is arranged on the door blade bottom plate 2.

[0049] The lock hook assembly 3 comprises a base 31, a moving seat 32 and a lock hook 33, the base 31 is arranged on the door machine bottom plate 1, the moving seat 32 is movably arranged on the base 31, and the lock hook 33 is rotatably arranged on the moving seat 32, the lock hook 33 has a locked position relative to the lock hook seat 4 and an unlocked position relative to the lock hook seat 4.

[0050] An elastic element 34 is arranged between the base 31 and the moving seat 32, the elastic element 34 is used for moving the moving seat 32 and the lock hook 33 relative to the base 31, so that the lock hook 33 is in contact with the baulk plate 5, and the lock hook 33 is used for rotating relative to the moving seat 32 and switching from the locked position to the unlocked position under the joint action of the elastic element 34 and the baulk plate 5.

[0051] Specifically, the elastic element 34 releases elastic potential energy, moves the moving seat 32 and the lock hook 33 relative to the base 31, when the elevator is located in the flat layer area, as shown in the drawings Figures 7-8 The lock hook 33 is in contact with the baulk plate 5 under the action of the elastic element 34, and the elastic element 34 continues to release the elastic potential energy, the lock hook 33 rotates under the action of the elastic element 34 and the baulk plate 5, and switches from the locked position to the unlocked position, at this time, the lock hook 33 unlocks the lock hook seat 4. When the elevator is located in the non-flat layer area, as shown in the drawings Figures 9-10 The lock hook 33 cannot contact the baulk plate 5, so the lock hook 33 maintains the locked position, and the lock hook 33 locks the lock hook seat 4.

[0052] Specifically, the elastic element 34 comprises a spring, but is not limited thereto.

[0053] The door protection device provided by the embodiment can prevent passengers from opening the door for self-rescue when the elevator car is not in the flat layer area, thereby avoiding the dangerous situation of falling into the shaft and improving the safety of the elevator. At the same time, it can effectively prevent passengers (especially children) from opening the elevator door, thereby reducing the risk of abnormal opening of the elevator door caused by external interference and protecting passengers from accidental injury. And it can ensure that the elevator door remains locked in the non-flat layer area, avoiding unstable operation or failure of the elevator caused by passengers opening the door. This helps to improve the overall operation quality and stability of the elevator.

[0054] The anti-pick door protection device provided in the embodiment is in contact with the impact arch plate 5 when the elevator is located in the landing area, and is unlocked under the action of the impact arch plate 5. When the elevator is located in the non-landing area, the anti-pick door protection device is separated from the impact arch plate 5, and the anti-pick door protection device cannot be unlocked. That is, the anti-pick door protection device provided in the embodiment can be unlocked only with the cooperation of the impact arch plate 5. The embodiment increases the unlocking difficulty to avoid the elevator landing door being opened due to user misoperation. Moreover, although the unlocking condition is more stringent, the passenger can still easily and quickly enter and exit the elevator when the elevator normally runs to the specified floor, which helps to improve the overall satisfaction and trust of users for the elevator.

[0055] The anti-pick door protection device provided in the embodiment is not limited by the door system and the type of door blade, and can adapt to various types of elevator door systems, has wide applicability, and can be widely used in elevators of different brands and models. Moreover, the anti-pick door protection device provided in the embodiment is independent of other structures of the elevator, which means that even if other parts of the elevator fail or are abnormal, the anti-pick door protection device provided in the embodiment can still remain effective, greatly improving the safety of the elevator and preventing safety accidents caused by pick door.

[0056] As shown in FIG. 1, Figures 1-6 In one embodiment, the locking hook 33 is rotatably arranged on the moving seat 32 through a first connecting structure 36, wherein the first connecting structure 36 is transversely arranged to enable the locking hook 33 to rotate in the longitudinal plane under the cooperation of the elastic member 34 and the impact arch plate 5.

[0057] The embodiment enables the locking hook 33 to rotate in the longitudinal plane under the cooperation of the elastic member 34 and the impact arch plate 5, that is, after the locking hook 33 is switched to the unlocking position and the elevator landing door is closed (i.e., the impact arch plate 5 is not in contact with the locking hook 33), the locking hook 33 can naturally fall under the action of gravity and be switched from the unlocking position to the locking position, achieving natural closing to ensure that the elevator landing door remains closed during subsequent elevator operation, improving the overall safety of the elevator system.

[0058] Moreover, the structure for achieving natural latching by gravity provided in the embodiment is simple and reliable, reduces the probability of failure events caused by complex mechanical structures, improves the stability of the elevator system, and reduces the cost of maintenance and repair.

[0059] In one embodiment, the first connecting structure 36 is transversely arranged relative to the horizontal plane to enable the locking hook 33 to rotate in the longitudinal plane under the cooperation of the elastic member 34 and the impact arch plate 5.

[0060] In one embodiment, the first connecting structure 36 is arranged parallel to the horizontal plane, so that the hook 33 rotates in a longitudinal plane perpendicular to the horizontal plane under the cooperation of the elastic member 34 and the crossbow plate 5.

[0061] As shown in the drawings, in one embodiment, the first connecting structure 36 comprises a rotating shaft 361, and the rotating shaft 361 is arranged on the surface of the moving seat 32 close to the hook 33 and penetrates the hook 33, so that the hook 33 is rotatably arranged on the moving seat 32. Figure Two

[0062] As shown in the drawings, in one embodiment, one end of the hook 33 is bent to form a hook portion 332, and the other end of the hook 33 is provided with the first connecting structure 36. Figures 1-6

[0063] The hook 33 is further provided with an unlocking member 3311 between the hook portion 332 and the first connecting structure 36, and the distance between the unlocking member 3311 and the first connecting structure 36 is less than the distance between the unlocking member 3311 and the hook portion 332, and the hook 33 is in contact with the crossbow plate 5 through the unlocking member 3311.

[0064] The embodiment makes the unlocking member 3311 away from the hook portion 332, and when the crossbow plate 5 acts on the unlocking member 3311, a longer force arm can be generated, so that the hook portion 332 is more easily rotated, and the hook 33 can have a long enough stroke to complete the unlocking action in the unlocking process, so as to ensure that the hook 33 is separated from the hook seat 4.

[0065] In addition, since the embodiment realizes the large rotation of the hook portion 332, when the crossbow plate 5 acts on the unlocking member 3311, the hook 33 can quickly drive the hook portion 332 to rotate and separate from the hook seat 4, so as to realize the quick unlocking and improve the unlocking efficiency.

[0066] In one embodiment, the unlocking member 3311 comprises a door ball.

[0067] As shown in the drawings, in one embodiment, the hook 33 is provided with a reset member 37, one end of the reset member 37 is arranged on the hook 33, and the other end of the reset member 37 is arranged on the connecting structure, and the reset member 37 is used to drive the hook 33 to rotate from the unlocking position to the locking position. Figures 1-6

[0068] ​​​The embodiment realizes automatic locking by setting the reset member 37, so as to ensure that the elevator landing door remains closed during subsequent elevator operation, and improves the overall safety of the elevator system. Moreover, the reset member 37 cooperates with the gravity drop lock structure, so as to ensure that the locking hook 33 is re-locked to the locking hook seat 4, and avoid the situation that the gravity drop lock function of the locking hook 33 fails when the locking hook 33 is disturbed by external force (such as wind, vibration, etc.), so as to ensure that the locking hook 33 can quickly return to the locked state, and further enhance the safety of the elevator.

[0069] In one embodiment, the reset member 37 includes a torsion spring, but is not limited thereto.

[0070] As shown in Figures 1-6 one embodiment, the locking hook 33 includes a locking hook body 331, an unlocking member 3311 is arranged on the locking hook 33 body, one end of the locking hook body 331 is bent relative to the locking hook body 331 to form a hook portion 332, the other end of the locking hook body 331 is bent relative to the locking hook body 331 to form a bent portion 333, and the first connecting structure 36 is located at the bent portion 333.

[0071] The moving seat 32 is provided with a limiting member 32111, which is located between the locking hook body 331 and the bent portion 333, so as to limit the rotation angle of the bent portion 333.

[0072] The embodiment limits the rotation amplitude of the locking hook 33 by setting the limiting member 32111, so as to prevent the locking hook 33 from excessively rotating under the joint action of the elastic member 34 and the strike bow plate 5, thereby reducing the risk that the locking hook 33 cannot be reset due to excessive rotation amplitude, reducing the safety risk caused by the locking hook 33 failing to reset, and improving the stability and reliability of the anti-pick door protection device.

[0073] Moreover, the end of the locking hook body 331 is bent relative to the locking hook body 331 to form the bent portion 333, so as to provide a containing space for the limiting member 32111, so that the limiting member 32111 can be neatly contained between the locking hook body 331 and the bent portion 333, avoiding the situation that the limiting member 32111 protrudes outward, so that the overall structure is compact, and the overall volume is reduced. Moreover, the space utilization rate is improved, and unnecessary space waste is avoided.

[0074] As shown in Figures 1-6 one embodiment, the moving seat 32 is provided with a mounting plate 321, the mounting plate 321 includes a mounting portion 3211 and a blocking portion 3212, the mounting portion 3211 is arranged on the moving seat 32, the limiting member 32111 is arranged on the mounting portion 3211, the first buffer member 32121 is arranged on the blocking portion 3212, and the first buffer member 32121 is used to contact the locking hook seat 4.

[0075] This embodiment, by setting a blocking part 3212, prevents the lock hook seat 4 from colliding with the limiting member 32111 under the action of the door knife base plate 2. Simultaneously, the first buffer member 32121 effectively reduces the impact force from the lock hook seat 4, mitigating damage to the blocking part 3212 and preventing deformation or breakage of the blocking part 3212. This enhances the durability of the anti-pry door protection device and extends its service life. Furthermore, the first buffer member 32121 also reduces the noise generated when the lock hook seat 4 collides with the blocking part 3212.

[0076] Specifically, the mounting part 3211 is arranged parallel to the movable base 32, and the blocking part 3212 is arranged perpendicular to the movable base 32.

[0077] In one embodiment, the first buffer 32121 includes a silicone component.

[0078] like Figures 1-6 As shown, in one embodiment, the first end of the base 31 and the first end of the movable seat 32 are slidably connected by a second connecting structure 38; the elastic element 34 is located between the second end of the base 31 and the second end of the movable seat 32.

[0079] This embodiment separates the second connecting structure 38 and the elastic element 34 into different positions, avoiding mutual interference between the second connecting structure 38 and the elastic element 34 during operation, ensuring that their respective functions can be performed normally, and helping to improve the stability and reliability of the anti-pry door protection device.

[0080] Furthermore, by rationally planning the positions of the second connecting structure 38 and the elastic element 34, this embodiment can make full use of limited space resources, so that the sliding connecting structure and the elastic element 34 are arranged in the best way between the base 31 and the movable seat 32, thereby improving space utilization and making the overall structure compact and reducing unnecessary space waste.

[0081] like Figures 1-6 As shown, in one embodiment, the second connection structure 38 includes a guide rail 381 and a slider 382. One of the first end of the base 31 and the first end of the movable seat 32 is provided with a guide rail 381, and the other of the first end of the base 31 and the first end of the movable seat 32 is provided with a slider 382. The guide rail 381 and the slider 382 are slidably connected.

[0082] The second connection structure 38 in this embodiment includes a guide rail 381 and a slider 382, ​​which helps to make the movement of the movable seat 32 relative to the base 31 more stable.

[0083] like Figures 1-6As shown, in one embodiment, the second end of the base 31 extends outward to form a first arm 311 and a second arm 312, and the second end of the movable seat 32 extends outward to form a third arm 322 and a fourth arm 323, both of which are located between the first arm 311 and the second arm 312.

[0084] The elastic element 34 is equipped with a guide rod 35. One end of the guide rod 35 is set on the first support arm 311, and the other end of the guide rod 35 passes through the third support arm 322 and the fourth support arm 323 and is set on the second support arm 312. The elastic element 34 is wound around the guide rod 35. One end of the elastic element 34 abuts against the first support arm 311, and the other end passes through the third support arm 322 and abuts against the fourth support arm 323.

[0085] In this embodiment, the elastic element 34 is equipped with a guide rod 35 so that when the elastic element 34 drives the movable seat 32, the guide rod 35 can provide stable support for the elastic element 34, ensuring the stability of the movement of the movable seat 32. Furthermore, the guide rod 35 can provide movement guidance for the elastic element 34, ensuring the accuracy of the movement of the movable seat 32. This helps to improve the stability and reliability of the anti-pry door protection device.

[0086] like Figures 1-6 As shown, in one embodiment, a second buffer 324 is provided on the second arm 312 and / or the fourth arm 323, and the second buffer 324 is located between the second arm 312 and the fourth arm 323.

[0087] In this embodiment, the second buffer 324 effectively reduces the impact force of the movable seat 32 on the base 31, mitigating the damage caused by the movable seat 32 to the base 31, and preventing deformation and breakage of the second support arm 312 and the fourth support arm 323. This enhances the durability of the anti-pry door protection device and extends its service life. Furthermore, the second buffer 324 also reduces the noise generated when the second support arm 312 and the fourth support arm 323 collide.

[0088] like Figures 1-10 As shown, this embodiment also provides an elevator, including the anti-pry door protection device described in any of the above embodiments.

[0089] The elevator provided in this embodiment includes an anti-pry door protection device, which prevents passengers from prying open the elevator doors to escape when the elevator car is not level with the floor, thereby avoiding the danger of falling into the shaft and improving elevator safety. It also effectively prevents passengers (especially children) from prying open the elevator doors, reducing the risk of abnormal door opening due to external interference and protecting passengers from accidental injury. Furthermore, it ensures that the elevator doors remain locked in non-level areas, preventing elevator instability or malfunction caused by passengers prying open the doors. This contributes to improving the overall operational quality and stability of the elevator.

[0090] The elevator provided in this embodiment includes an anti-pry door protection device. When the elevator is in a leveling area, the anti-pry door protection device contacts the impact plate 5 and unlocks under the action of the impact plate 5. When the elevator is in a non-leveling area, the anti-pry door protection device separates from the impact plate 5 and cannot unlock. In other words, the anti-pry door protection device provided in this embodiment can only unlock with the cooperation of the impact plate 5. This embodiment increases the difficulty of unlocking and avoids the elevator door opening due to user misoperation. Furthermore, although the anti-pry door protection device provided in this embodiment makes the unlocking conditions more stringent, passengers can still easily and quickly enter and exit the elevator when it reaches the designated floor during normal operation, which helps to improve users' overall satisfaction and trust in the elevator.
