[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0025] like Figure 1-2 As shown, an existing building elevator with face recognition includes an outdoor elevator 1, which can be installed outside the existing building. An outdoor elevator door 2 is provided at the lower part of the outer side of the outdoor elevator 1. After the user opens the outdoor elevator door 2, the user can enter the interior of the outdoor elevator 1.

[0026] Among them, Figure 1-2 As shown, the core of the technical solution is that a bracket group is installed on the outer side of the outdoor elevator 1, and a rotating seat is installed on the bracket group. A face recognition device 4 is fixedly connected to the rotating seat. When the outdoor light intensity is high and affects the recognition of the face recognition device 4, the angle of the face recognition device 4 can be adjusted by the rotating seat to reduce the impact of outdoor light on the face recognition device 4, improve the accuracy of outdoor recognition of the face recognition device 4, reduce the phenomenon that the face recognition device 4 cannot effectively recognize the user due to the high outdoor light intensity, and further reduce the phenomenon that the user cannot use the outdoor elevator 1 because the face recognition device 4 cannot effectively recognize the user.

[0027] Here, in order to further reduce the influence of outdoor light, a sunshade 10 is fixedly connected to the outside of the face recognizer 4 to block the light and reduce the light shining on the face recognizer 4. An identification opening is provided on the outside of the sunshade 10, and the face recognizer 4 interacts with the user through the identification opening.

[0028] Furthermore, in order to ensure that the light intensity meets the requirements, a fill light 13 is installed inside the sunshade 10. At this time, when the light intensity is insufficient, the fill light 13 can be used for fill light.

[0029] Among them, Figure 1-3 As shown, the rotating seat can be a manual rotating seat, that is, a manual turntable, or an electric rotating seat, that is, the rotating seat includes a first servo motor 3 and a control unit, the first servo motor 3 is fixedly connected to the bracket group, the output end of the first servo motor 3 and the face recognizer 4 are fixedly connected, the control unit can be fixedly connected to the bracket group, the outside of the outdoor elevator 1 or other positions, it is electrically connected to the first servo motor 3, and can control the first servo motor 3 to adjust the angle of the face recognizer 4.

[0030] Here, one structure of the control unit includes a manual controller and a host, the manual controller and the host can be fixed on an outdoor elevator 1 or a bracket group, the manual controller and the first servo motor 3 are electrically connected to the host, at this time, the user can directly control the first servo motor 3 to adjust the rotation angle of the face recognition device 4 through the manual controller.

[0031] Another structure of the control unit includes a photosensor 11 and a host. The host can be fixedly connected to an outdoor elevator 1 or a bracket group. The outdoor elevator 1 is fixedly connected to the outside of the sunshade 10. The photosensor 11 and the first servo motor 3 are electrically connected to the host. At this time, when the host is started, the light intensity around the face recognizer 4 will be detected by the photosensor 11, and then the direction closest to the set value will be selected to control the first servo motor 3 to drive the face recognizer 4 to rotate so that the face recognizer 4 is facing the above-selected direction.

[0032] Among them, Figure 1-3 As shown, the bracket group is disclosed herein, and the bracket group can be a plate-shaped fixed bracket, or it can be as shown in FIG. Figure 1-2 As shown, it includes an outer bracket 6 fixedly connected to the outside of the outdoor additional elevator 1, a horizontal moving group is installed on the outer bracket 6, a movable bracket 5 is installed on the horizontal moving group, and a first servo motor 3 is assembled on the movable bracket 5. When the face recognizer 4 is not needed for recognition and enters the standby state, the first servo motor 3 can drive the sunshade 10 to rotate so that the recognition opening of the sunshade 10 is opposite to the outdoor additional elevator 1, and then the movable bracket 5 is moved by the horizontal moving group so that the sunshade 10 and the outdoor additional elevator 1 are offset. At this time, the sunshade 10 and the outdoor additional elevator 1 form a sealed protection structure located on the outside of the face recognizer 4, which reduces the damage to the face recognizer 4 caused by long-term exposure to rain, sunlight and wind when it is in the standby state.

[0033] The shading hood 10 has one side with an identification opening and a sealing gasket 12 is fixedly connected to the outer side of the identification opening. The sealing gasket 12 can reduce the gap between the shading hood 10 and the outdoor elevator 1 to ensure the sealing performance.

[0034] Meanwhile, a cooling fan may be installed on the light shield 10, and a temperature sensor may be installed inside the light shield 10. When the temperature inside the light shield 10 exceeds a standard, the cooling fan is automatically started to dissipate heat.

[0035] In order to improve the degree of intelligence and facilitate user use, the horizontal moving group and the first servo motor 3 are electrically connected with a start button 9 and a time relay. When the start button 9 is started, the horizontal moving group and the first servo motor 3 will be automatically started to drive the face recognizer 4 and the light shield 10 to reset, and then the time relay will be started. When the set time is reached, the time relay sends a return signal, so that the first servo motor 3 drives the light shield 10 to rotate, and the horizontal moving group drives the light shield 10 and the face recognizer 4 to move, until the light shield 10 and the outdoor installed elevator 1 form a sealed protection structure located on the outside of the face recognizer 4 again, to protect the face recognizer 4 and enter the standby state, so that the face recognizer 4 can be automatically protected.

[0036] See also Figure 3 As shown, the horizontal moving group can be an electric push rod, a motor-screw combination or other mechanisms capable of linear movement. In the present technical solution, a motor-screw combination is preferred. Specifically, the horizontal moving group includes a second servo motor 8 fixedly connected to the outer bracket 6, and the output end of the second servo motor 8 is fixedly connected to a threaded rod 7. The threaded rod 7 and the movable bracket 5 are threadedly connected. By starting the movable bracket 5, the threaded rod 7 can be driven to rotate to adjust the position of the movable bracket 5. Its structure is relatively simple and the cost is low.

[0037] The working principle of the utility model is as follows: when in use, the user adjusts the angle of the face recognition device 4 through the rotating seat to reduce the influence of outdoor light on the face recognition device 4, and then stands in the recognition area of ​​the face recognition device 4, the identity of the user can be recognized by the face recognition device 4, and the user's authority can be read. If the user has the authority to use the outdoor installed elevator 1, the outdoor door 2 of the elevator will be automatically opened.

[0038] In summary, the technical solution adjusts the angle of the face recognizer 4 through the rotating seat, reduces the impact of outdoor light on the face recognizer 4, can improve the accuracy of outdoor recognition of the face recognizer 4, and reduce the phenomenon that the face recognizer 4 cannot effectively recognize the user due to the high outdoor light intensity, and further reduce the phenomenon that the user cannot use the outdoor installed elevator 1 due to the inability of the face recognizer 4 to effectively recognize the user.

[0039] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
