Description

Technical Field

[0001] The utility model relates to the technical field of intelligent elevators, in particular to an intelligent elevator device with a face recognition function. Background Art

[0002] An elevator is a mechanical device that can run along a set route and is used to provide up and down transportation for people or goods. It consists of an elevator shaft, one or more elevator doors, an elevator machine room, an elevator mechanical system and an elevator control system. Facial recognition is a computer vision technology that can identify facial features from an image. It uses feature points such as nose, eyes, and mouth to identify a person's face and compare it with photos in a database. Facial recognition technology can be used for security, identity authentication and other applications. For elevators in some special areas, facial recognition functions will be installed in the elevator for control locations and designed into an intelligent elevator device.

[0003] Publication number CN220431954U proposes an intelligent elevator device with facial recognition capabilities, which includes a longitudinal slide block with a facial recognition lens installed inside. Second transmission threaded rods are provided at both upper and lower ends of the exterior of the longitudinal slide block, and a transparent viewing glass is provided at the front end of the facial recognition lens. Second sliding limiting plates are provided on both sides of the second transmission threaded rod. This utility model solves the problem of existing facial recognition elevators where the camera lens used for facial recognition is exposed outdoors for long periods of time during actual use and is easily damaged by external collisions. This utility model drives the longitudinal slide block to adjust its horizontal height longitudinally by limiting the vertical movement, and a hanging fixed frame wraps and secures the longitudinal slide block and the facial recognition lens inside the longitudinal slide block.

[0004] And the publication number CN214989462U proposes an intelligent elevator device with a facial recognition function, which includes an elevator device body, elevator doors, a facial recognition device, a facial recognition probe, and an emergency lighting lamp. The elevator device body is equipped with an elevator door on one side, and an indicator light is installed on the outer wall of the top of the elevator device body. Floor controllers are installed on the inner walls of the elevator device body on both sides of the elevator door, and the surface of the floor controllers is equipped with evenly spaced floor buttons. An emergency lighting switch is installed on the inner wall of the bottom of the elevator device body, and a control box is fixed on the inner wall of the top of the elevator device body. This utility model not only realizes the facial recognition function, making the use of the elevator more intelligent, but also can collect facial information of people in the elevator, and can promptly alert security personnel for strangers. It also facilitates the provision of lighting after a power outage due to an elevator failure, reducing the panic of trapped people.

[0005] Among the above-mentioned existing technologies, two of them have facial recognition devices respectively set on the elevator buttons and on an independent bracket outside the elevator door to facilitate facial recognition of elevator passengers. However, in actual use, these two facial recognition devices need to be set up one on each floor. If the floors are high or there are many buildings, this will greatly increase the cost of actual use, thereby reducing practicality. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an intelligent elevator device with a face recognition function, so as to solve the technical problems mentioned in the above background technology.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions:

[0008] An intelligent elevator device with a facial recognition function includes an elevator door frame, two outer doors, two inner doors, and a facial recognition mechanism. The two outer doors are slidably mounted within the elevator door frame. The two inner doors are each provided with a groove on one side adjacent to the outer doors. The two grooves are interconnected, and a control member is disposed within the groove.

[0009] The control component includes two rotating shafts, two torsion springs, two outer gear rings, two shift plates and two limiting grooves, the two rotating shafts are respectively fixedly installed in the two grooves, the two torsion springs are respectively sleeved on the two rotating shafts, and one end of the torsion spring is fixedly connected to the outer peripheral side of the rotating shaft, the two outer gear rings are respectively sleeved on the outer sides of the two torsion springs, and the outer gear ring is fixedly connected to the end of the torsion spring, the outer gear ring is rotatably connected to the top side wall of the groove, the two shift plates are respectively fixedly connected to the outer peripheral sides of the two outer gear rings, the two limiting grooves are respectively opened on the side of the two outer doors close to the inner door, the ends of the two shift plates extend into the corresponding limiting grooves, a tooth plate is connected between the two outer gear rings, and the face recognition mechanism is embedded in the end of the tooth plate and fixedly connected to the tooth plate.

[0010] In a preferred example, the present invention can be further configured as follows: a limiting plate is connected to the top side of the tooth plate, a sliding groove is provided on the top side wall of the groove close to the limiting plate, and the top side of the limiting plate extends into the sliding groove and is slidably connected to the sliding groove.

[0011] In a preferred example, the present invention can be further configured as follows: a gap is left between the side of the tooth plate close to the outer door and the outer door, and a gap is left between the tooth plate and the inner side wall of the groove.

[0012] In a preferred example, the present invention can be further configured as follows: the length of the limiting groove is greater than the thickness of the shift plate, and the inner side walls of the two limiting grooves close to each other are respectively fitted with the corresponding sides of the shift plate.

[0013] In a preferred example, the present invention can be further configured as follows: a sliding groove corresponding to the shift plate is opened on a side of the outer door close to the inner door, and the sliding groove is on the moving path of the shift plate.

[0014] In summary, the present invention has at least one of the following beneficial technical effects:

[0015] 1. This intelligent elevator device with facial recognition functionality can install a facial recognition mechanism directly on the inner door during use, allowing it to move with the inner door. Furthermore, the facial recognition probe can be exposed when the outer door is opened slightly to perform facial recognition. This eliminates the need to install a facial recognition mechanism on every floor, thereby reducing operating costs and subsequent maintenance costs.

[0016] 2. This intelligent elevator device with facial recognition function has a limiting plate connected to the top side of the tooth plate, and the limiting plate is slidably connected to the slide groove on the top side wall of the groove. Therefore, when the two inner doors are opened, the inner door with the slide groove will directly pull the tooth plate away, preventing the tooth plate from falling and affecting the subsequent use of the facial recognition mechanism;

[0017] 3. This intelligent elevator device with facial recognition function has a gap between the tooth plate on the side closest to the outer door and the outer door. This prevents the tooth plate and the facial recognition mechanism from colliding with the outer door when the outer door is initially opened, thereby damaging the facial recognition mechanism and affecting its use. Furthermore, a gap is left between the tooth plate and the inner sidewall of the groove to prevent the inertia caused by the rotation of the torsion spring from causing the tooth plate to collide with the inner sidewall of the groove, thereby causing vibration and damage to the facial recognition mechanism.

[0018] 4. This intelligent elevator device with facial recognition function has a limiting groove that is longer than the thickness of the dial plate. When the dial plate is moved, the limiting groove can avoid the movement of the dial plate end, preventing the dial plate from contacting the inner sidewall of the limiting groove, thereby affecting the movement of the facial recognition mechanism to the outside for facial recognition.

[0019] 5. This intelligent elevator device with facial recognition function has a sliding groove corresponding to the toggle plate on the side of the outer door close to the inner door, and the sliding groove is on the moving path of the toggle plate. Therefore, when the elevator car moves, it will drive the entire inner door to move, and then drive the toggle plate to move. When the toggle plate moves, it will slide in the corresponding sliding groove, thereby avoiding the toggle plate from colliding with the elevator outer door, which will cause damage to the toggle plate and affect the subsequent use of the facial recognition function.

[0025] The present invention will be described in further detail below with reference to the accompanying drawings.

[0026] Example:

[0027] Reference Figure 1-Figure 3 The utility model discloses an intelligent elevator device with a face recognition function, comprising an elevator door frame 1, two outer doors 2, two inner doors 3, and a face recognition mechanism 4. The two outer doors 2 are slidably mounted in the elevator door frame 1. The two inner doors 3 are each provided with a groove 5 on one side close to the outer door 2. The two grooves 5 are connected to each other, and a control member 6 is provided in the groove 5.

[0028] The control member 6 includes two rotating shafts 7, two torsion springs 8, two outer gear rings 9, two shift plates 10 and two limiting grooves 11. The two rotating shafts 7 are respectively fixedly installed in the two grooves 5, and the two torsion springs 8 are respectively sleeved on the two rotating shafts 7, and one end of the torsion spring 8 is fixedly connected to the outer peripheral side of the rotating shaft 7, the two outer gear rings 9 are respectively sleeved on the outer sides of the two torsion springs 8, and the outer gear ring 9 is fixedly connected to the end of the torsion spring 8, the outer gear ring 9 is rotatably connected to the top side wall of the groove 5, the two shift plates 10 are respectively fixedly connected to the outer peripheral sides of the two outer gear rings 9, the two limiting grooves 11 are respectively opened on the side of the two outer doors 2 close to the inner door 3, and the ends of the two shift plates 10 extend into the corresponding limiting grooves 11, a toothed plate 12 is connected between the two outer gear rings 9, and the face recognition mechanism 4 is embedded in the end of the toothed plate 12 and fixedly connected to the toothed plate 12.

[0029] In this embodiment, when in use, the user stands outside the elevator outer door 2, then faces the position between the two outer doors 2, and then presses the elevator up and down control button. At this time, after the elevator outer door 2 receives the command, the outer door 2 will first open a certain gap. Then, when the outer door 2 opens, it will push the dial plate 10 through the inner wall of the limiting groove 11. After being pushed, the dial plate 10 will drive the outer gear ring 9 to rotate. When the outer gear ring 9 rotates, it will drive the meshing gear plate 12 to move to the position between the two outer doors 2. At this time, the probe of the face recognition mechanism 4 will be exposed, thereby performing face recognition on the user standing outside the elevator outer door 2. After successful recognition, the inner door 3 will open synchronously with the outer door 2, and the elevator can be used at this time;

[0030] If the face recognition fails, the elevator outer door 2 will be closed directly. When the dial plate 10 and the outer gear ring 9 are pushed to rotate, the torsion spring 8 will also be twisted. At this time, the torsion spring 8 will exert a reaction force on the outer gear ring 9. After the elevator outer door 2 is closed, the dial plate 10 loses its restriction, and then the torsion spring 8 will drive the outer gear ring 9 to rotate, and then drive the dial plate 10 to return to its original position, and at the same time drive the tooth plate 12 and the face recognition mechanism 4 to return to their original position, to prevent the face recognition mechanism 4 from being clamped.

[0031] In a further preferred embodiment of the present invention, Figure 3 As shown, the top side of the tooth plate 12 is connected to a limiting plate 13 , and a sliding groove 14 is provided on the top side wall of the groove 5 near the limiting plate 13 . The top side of the limiting plate 13 extends into the sliding groove 14 and is slidably connected to the sliding groove 14 .

[0032] In this embodiment, a limiting plate 13 is connected to the top side of the tooth plate 12, and the limiting plate 13 is slidably connected to the slide groove 14 on the top side wall of the groove 5. Therefore, when the two inner doors 3 are opened, the inner door 3 with the slide groove 14 will directly pull away the tooth plate 12 to prevent the tooth plate 12 from falling, thereby affecting the subsequent use of the face recognition mechanism 4.

[0033] In a further preferred embodiment of the present invention, Figure 3 As shown, a gap is left between the side of the tooth plate 12 close to the outer door 2 and the outer door 2 , and a gap is left between the tooth plate 12 and the inner side wall of the groove 5 .

[0034] In this embodiment, a gap is left between the tooth plate 12 and the outer door 2 on the side close to the outer door 2, so that when the outer door 2 is initially opened, the tooth plate 12 and the face recognition mechanism 4 are prevented from colliding with the outer door 2, thereby causing damage to the face recognition mechanism 4, thereby affecting the use of the face recognition mechanism 4. At the same time, a gap is left between the tooth plate 12 and the inner wall of the groove 5 to avoid the inertia brought by the rotation of the torsion spring 8, causing the tooth plate 12 to collide with the inner wall of the groove 5, thereby causing the face recognition structure to be vibrated and damaged.

[0035] In a further preferred embodiment of the present invention, Figure 3 As shown, the length of the limiting groove 11 is greater than the thickness of the shifting plate 10 , and the inner side walls of the two limiting grooves 11 close to each other are respectively fitted with the corresponding sides of the shifting plate 10 .

[0036] In this embodiment, the length of the limiting groove 11 is greater than the thickness of the dial plate 10. When the dial plate 10 is dialed, the limiting groove 11 can avoid the movement of the position of the end of the dial plate 10, thereby preventing the dial plate 10 from being interfered with by the inner wall of the limiting groove 11 in the limiting groove 11, thereby affecting the movement of the face recognition mechanism 4 to the outside for face recognition.

[0037] In a further preferred embodiment of the present invention, Figure 3 As shown, a sliding groove 15 corresponding to the shift plate 10 is opened on a side of the outer door 2 close to the inner door 3 , and the sliding groove 15 is on the moving path of the shift plate 10 .

[0038] In this embodiment, a sliding groove 15 corresponding to the toggle plate is provided on the side of the outer door 2 close to the inner door 3, and the sliding groove 15 is on the moving path of the toggle plate 10. Therefore, when the elevator car moves, it will drive the entire inner door 3 to move, and then drive the toggle plate 10 to move. When the toggle plate 10 moves, it will slide in the corresponding sliding groove 15, thereby avoiding the toggle plate 10 from colliding with the elevator outer door 2, which will cause damage to the toggle plate 10, thereby affecting the subsequent use of the face recognition function.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
