[0032] Combine the following Figure 1-3 The utility model describes the access control device provided by the utility model.

[0033] like Figure 1 and Figure 2 As shown, the utility model provides an access control device 1, comprising: a shell 11, functional devices and a transparent cover 12 and a control main board (not shown in the figure); the functional devices are installed on the shell 11; the transparent cover 12 is installed on the shell 11; an electrochromic film 13 is provided on the side of the transparent cover 12 facing the shell 11; the electrochromic film 13 is divided into a first color-changing area 132 and a second color-changing area 133, the first color-changing area 132 is arranged corresponding to at least part of the functional devices, and the second color-changing area 133 is arranged corresponding to the area other than the functional devices; the control main board is installed in the shell 11, and the first color-changing area 132, the second color-changing area 133 and the functional devices are electrically connected to the control main board respectively.

[0034] In this embodiment, the housing 11 is the outer shell of the entire access control device 1. The interior of the housing 11 is used to accommodate the internal circuit and control mainboard of the access control device 1, and the side wall of the housing 11 is used to install and fix various functional devices (such as a shooting device, a fill light device, a card reader, etc.). By installing a transparent cover plate 12 on the housing 11, the functional devices are protected without affecting the functions of the functional devices. At the same time, an electrochromic film 13 is provided on the side of the transparent cover plate 12 opposite to the housing 11. The electrochromic film 13 is divided into a first color-changing area 132 and a second color-changing area 133. The first color-changing area 132 and the second color-changing area 133 can change color and transparency respectively under the action of the control mainboard. Among them, the second color-changing area 133 can be changed into a black and opaque state, which has a certain shielding effect on the shell 11; and the first color-changing area 132 corresponds to at least part of the functional device settings. When the part of the functional device is on standby or turned off, the first color-changing area 132 can be adjusted to the same or similar color as the second color-changing area 133. While shielding the shell 11, it ensures that the color of the entire electrochromic film 13 is coordinated and more beautiful. When the part of the functional device is started, the first color-changing area 132 is adjusted to a light-transmitting state accordingly so that the functional device can function normally. It can be understood that the control motherboard controls the blackening degree of the electrochromic film 13 by adjusting the voltage of the electrochromic film 13, thereby realizing stepless regulation of the blackening degree between 100% and 0%.

[0035] It is understandable that the first color-changing area 132 may only correspond to some functional devices, and the electrochromic film 13 may be provided with first avoidance holes 131 corresponding to the remaining functional devices. These functional devices directly realize their own functions through the first avoidance holes 131 so that these functional devices can operate normally.

[0036] The access control device 1 of the utility model arranges a control mainboard and corresponding circuits in a shell 11, and installs functional devices and a transparent cover plate 12 on the shell 11, and the transparent cover plate 12 can protect the functional devices; at the same time, an electrochromic film 13 is arranged on the side of the transparent cover plate 12 facing the shell 11, and the electrochromic film 13 is divided into a first color-changing area 132 and a second color-changing area 133 whose color and transparency can be changed independently, wherein the first color-changing area 132 can be adjusted to a light-transmitting state when the corresponding functional device is running, so that the functional device can function normally through the first color-changing area 132, and the second color-changing area 133 can be adjusted to a black light-opaque state, thereby shielding the shell 11, and there is no need to screen-print black ink on the inner side of the cover plate, which is not easy to fall off, and effectively solves the problem in the prior art that the ink in the access control cover plate is easy to fall off, affecting the appearance and service life of the equipment.

[0037] Optionally, glue may be dispensed on the side of the transparent cover plate 12 facing the housing 11 to bond the transparent cover plate 12 and the housing 11 together.

[0038] Optionally, in some embodiments, Figure 1 and Figure 3 As shown, the electrochromic film 13 covers the transparent cover plate 12, and the first color-changing area 132 is arranged corresponding to all functional devices.

[0039] In this embodiment, by covering the entire transparent cover plate 12 with the electrochromic film 13, the electrochromic film 13 can change the color of the entire transparent cover plate 12 coverage area under the control of the control mainboard; wherein, the first color changing area 132 corresponds to all functional device settings, and when the functional device is on standby or turned off, the first color changing area 132 can be adjusted to the same or similar color as the second color changing area 133, which shields the shell 11 while ensuring that the color of the entire electrochromic film 13 and the entire transparent cover plate 12 is coordinated and more beautiful, and when these functional devices are started, the first color changing area 132 is correspondingly adjusted to a light-transmitting state so that the functional devices can function normally; the second color changing area 133 is usually maintained at the target color (usually black), thereby providing a continuous shielding effect on the shell 11.

[0040] Optionally, in some embodiments, Figure 1 and Figure 3 As shown, the first color-changing area 132 includes a plurality of sub-areas, and the plurality of sub-areas are arranged in one-to-one correspondence with each functional device, and the plurality of sub-areas are electrically connected to the control mainboard respectively.

[0041] In this embodiment, by dividing the first color-changing area 132 into a plurality of sub-areas, the plurality of sub-areas are electrically connected to the control mainboard respectively, and the control mainboard can control the voltage of each sub-area respectively to change the color and transmittance of each sub-area. At the same time, the sub-areas and each functional device are set in a one-to-one correspondence, so that the control mainboard controls the corresponding sub-areas separately according to the operation of each functional device, so as to be applicable to the situation where different functional devices have different operation states at the same time. For example, some functional devices need to be turned on for a long time, and the corresponding sub-areas can be maintained in a specific color; some functional devices need to be turned on under specific circumstances, and remain in standby or shut down to save energy under non-specific circumstances, then the corresponding sub-areas remain transparent when the functional device is turned on, and change the color to shield the functional device when the functional device is turned off or on standby, and the changed color can be set according to customer needs.

[0042] Specifically, in some embodiments, Figure 1 and Figure 3 As shown, a first insulating layer 134 is provided between the first color changing region 132 and the second color changing region 133 .

[0043] In this embodiment, a first insulating layer 134 is provided between the first color changing zone 132 and the second color changing zone 133 to insulate and isolate the first color changing zone 132 and the second color changing zone 133, thereby preventing charge flow and mutual interference between the first color changing zone 132 and the second color changing zone 133 when the control main board controls the power supply to the first color changing zone 132 or the second color changing zone 133, resulting in unstable color and transmittance of the first color changing zone 132 or the second color changing zone 133 and poor control effect.

[0044] Optionally, the first insulating layer 134 may be an ionic insulating layer, such as an aluminum oxide (Al2O3), silicon nitride (Si3N4) or silicon oxide (SiO2) insulating layer, etc. These insulating layers have good insulating properties and stability, can effectively isolate different parts of the circuit, and can also provide protection for electronic devices.

[0045] Optionally, the first insulating layer 134 is a carbon film or a graphene film. The carbon film or the graphene film is black. In order to play a shielding role, the color of the second color-changing area 133 is usually set to a darker color (such as black). By setting the first insulating layer 134 to a carbon film or a graphene film, the color of the first insulating layer 134 is close to or consistent with the color of the second color-changing area 133, making the entire device more beautiful.

[0046] Optionally, in some embodiments, the functional device includes a camera, a white light fill light and an infrared light fill light.

[0047] In this embodiment, the camera is used to capture images of human faces and send the images to the control mainboard for image recognition; by setting a white light fill light and an infrared light fill light, the white light fill light can be turned on to supplement the light when the external light is insufficient, so that the camera can capture clear images and improve the face recognition effect under insufficient light conditions; the infrared light fill light cooperates with the camera to achieve covert shooting. When the external light is insufficient (for example, at night), the control mainboard controls the white light fill light or the infrared light fill light to turn on for fill light, and controls the white light fill light, the infrared light fill light and the camera to remain in a powered off or standby state when not in use, saving power.

[0048] Based on the above embodiment, a sub-area of ​​the first color-changing area 132 may be respectively set corresponding to the camera, the white light fill light and the infrared light fill light, and the second color-changing area 133 covers the part outside each functional device.

[0049] The control method of each color changing area is as follows:

[0050] For the second color changing area 133, during normal operation, the color of the second color changing area 133 remains at the target color. The target color is usually black, and can also be adjusted according to actual usage requirements. Specifically, the control mainboard can be electrically connected to the second color changing area 133 through a voltage division control circuit to adjust the voltage of the second color changing area 133, thereby achieving stepless regulation of the blackening degree of the second color changing area 133 between 100% and 0%.

[0051] like Figure 3 As shown, the first color-changing area 132 needs to be divided into multiple sub-areas according to the functional components. For example, the sub-area corresponding to the camera is the first sub-area 1321, the sub-area corresponding to the infrared light fill light is the second sub-area 1322, and the sub-area corresponding to the white light fill light is the third sub-area 1323.

[0052] For the first sub-area 1321, when there is no need to shoot, the color of the first sub-area 1321 is consistent or similar to that of the second color-changing area 133. For example, the control mainboard can be electrically connected to the sub-area through a voltage-dividing control circuit, and when there is no need to shoot and collect faces, the voltage of the first sub-area 1321 is consistent with the voltage of the second color-changing area 133, so that the colors of the first sub-area 1321 and the second color-changing area 133 are consistent. When it is necessary to shoot and collect faces, the sub-area is adjusted to a transparent state. For example, when it is necessary to shoot and collect faces, the blackening degree of the sub-area corresponding to the control camera is 0%, which does not affect the collection effect of the face.

[0053] It is easy to understand that when shooting is not required, the voltage of the first sub-area 1321 can also be set according to actual needs, so that the color of the first sub-area 1321 can be changed to the color required by the customer.

[0054] For the second sub-area 1322, since the area corresponding to the infrared light fill light has a transmittance requirement for light of a specific wavelength, the second sub-area 1322 needs to be maintained at a specific color to ensure that the best fill light effect can be achieved while also playing a shielding role. Specifically, for the second sub-area 1322, in the early stage of design, the voltage of the second sub-area 1322 is controlled to adjust its blackening degree and meet the transmittance requirement for light of a specific wavelength. After the user determines the desired effect, the voltage of the second sub-area 1322 can be maintained at this voltage.

[0055] For the third sub-area 1323, when fill light is not needed, the color of the third sub-area 1323 is consistent with the second color-changing area 133. Specifically, the control mainboard can be electrically connected to the third sub-area 1323 through a voltage-dividing control circuit to control the voltage of the third sub-area 1323 to be consistent with the voltage of the second color-changing area 133, so that the colors of the third sub-area 1323 and the second color-changing area 133 are consistent. When fill light and face shooting and collection are required, the third sub-area 1323 is adjusted to be transparent. For example, the control mainboard controls the blackening degree of the third sub-area 1323 to 0%, presenting the white light fill light effect to the greatest extent, and reducing the attenuation of the fill light.

[0056] Specifically, a DSP (Digital Signal Processing) chip may be provided on the control main board, and the DSP chip cooperates with each voltage-dividing control circuit to realize PWM (Pulse width modulation) voltage control of each sub-area.

[0057] Specifically, the camera may be a binocular camera. By adopting a binocular camera, the camera can achieve stereoscopic vision, and the captured image is clearer, which is conducive to improving the efficiency and accuracy of facial recognition.

[0058] In some embodiments, Figure 1 and Figure 3 As shown, the access control device 1 also includes a display screen 15, which is embedded in the housing 11, and the transparent cover 12 covers the display screen 15. The electrochromic film 13 is provided with a second avoidance hole 135 at a position corresponding to the display screen 15; the display screen 15 is electrically connected to the control main board.

[0059] In this embodiment, the display screen 15 is electrically connected to the control main board, and can be used to display the image captured by the access control device 1, so that the user can adjust the position so that the access control device 1 can capture a complete and clear facial image, which is convenient for identification; by setting a second avoidance hole 135 on the electrochromic film 13 corresponding to the display screen 15, the electrochromic film 13 will not block the display screen 15, so that the user can view the image displayed on the display screen 15.

[0060] In some embodiments, Figure 3 As shown, a second insulating layer 136 is disposed at the edge of the second avoidance hole 135 .

[0061] In this embodiment, by providing the second insulating layer 136 at the edge of the second avoidance hole 135 , leakage at the edge of the second avoidance hole 135 can be avoided, and the structure is simple, convenient and practical.

[0062] Optionally, the second insulating layer 136 may be an ion insulating layer, such as an aluminum oxide (Al 2 O 3 ), silicon nitride (Si 3 N 4 ) or silicon oxide (SiO 2 ) insulating layer.

[0063] Specifically, in some embodiments not shown, a waterproof layer is disposed around the outer edge of the electrochromic film 13 .

[0064] In this embodiment, a waterproof layer is provided at the edge of the electrochromic film 13 to seal the outer side of the electrochromic film 13, thereby preventing moisture from penetrating into the electrochromic film 13 from the gap between the transparent cover plate 12 and the housing 11, thereby preventing the electrochromic film 13 from short-circuiting.

[0065] The above described embodiments are merely illustrative, and some or all of the modules may be selected according to actual needs to achieve the purpose of the embodiments. Those skilled in the art may understand and implement the embodiments without creative effort.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
