Description

Technical Field

[0001] This utility model relates to the technical field of advertising screen devices, specifically to a fingerprint recognition advertising screen quick maintenance device. Background Technology

[0002] Advertising, as the name suggests, is the act of widely disseminating information, that is, informing the general public about something. Nowadays, advertising mostly refers to the means by which businesses or non-profit organizations, for the purpose of promoting goods, providing services, or organizing public welfare activities, disseminate information about goods, services, or public welfare activities to consumers or users through advertising media, either for a fee or free. This is typically done through advertising screens in public places such as shopping malls and train stations. In recent years, the advertising industry has developed rapidly, advertising screen technology has continuously improved, and its application scope has become increasingly wide, covering almost all aspects of society, such as sports, finance, transportation, and outdoor advertising, which have become fiercely contested areas in the advertising industry. Currently, the popular form of advertising is the use of electronic advertising screens, which can provide the public with a rich variety of advertising content. However, such advertising screens have the following drawbacks: advertising screens in public places require daily content updates and maintenance. This maintenance involves multiple aspects, including hardware maintenance and repair, as well as the maintenance and updating of the displayed content. Because the advertising screens are located in public places, both the hardware and the displayed content are relatively easy to be tampered with by unauthorized personnel. Furthermore, adding protective measures to the advertising screens themselves would correspondingly increase equipment costs and maintenance costs. Some existing solutions enhance device security by incorporating fingerprint unlocking devices, which can only be unlocked by administrators. However, these existing fingerprint recognition devices are typically located in plain sight, making them easily visible to the average person and thus vulnerable to vandalism. Utility Model Content

[0003] The purpose of this invention is to provide a fingerprint recognition advertising screen quick maintenance device that can improve its security performance without adding extra equipment.

[0004] To achieve the above objectives, the present invention proposes the following technical solution:

[0005] A fingerprint recognition advertising screen quick maintenance device includes a display screen body and a functional back plate. The functional back plate is connected to the back of the display screen body via a smart buckle. A support plate is provided at the bottom of the functional back plate. The support plate is disposed opposite to the back of the display screen body, and a gap is reserved between the support plate and the back of the display screen body. A fingerprint sensor is provided on each side of the inner surface of the support plate. The fingerprint sensor is electrically connected to the smart buckle.

[0006] As a preferred embodiment of this utility model, the width of the gap between the tray and the back of the display screen body is 3-4cm.

[0007] As a preferred technical solution of this utility model, the two sides of the tray are provided with side baffles. The inner edge of the side baffle is connected to the back of the display screen body, and the outer edge of the side baffle is connected to the side edge of the tray. The two side baffles, the tray and the back of the display screen body are surrounded to form a fingerprint unlocking groove with an opening at the bottom.

[0008] As a preferred embodiment of this utility model, the depth of the fingerprint unlocking groove is 6-8cm.

[0009] As a preferred technical solution of this utility model, the back of the display screen body is provided with a pair of oppositely arranged fixing brackets.

[0029] To address the technical problem that existing advertising screens located in public places are prone to hardware damage or content tampering due to the exposed unlocking position of their maintenance ports, this utility model provides a fingerprint recognition-based quick maintenance device for advertising screens, which can improve the security performance of advertising screens without adding additional equipment.

[0030] like Figure 1-3 As shown, the advertising screen quick maintenance device of this utility model embodiment includes a display screen body 1 and a functional backplate 2. The display screen body 1 is used to display and play advertising content, while the functional backplate 2 is used for signal processing and is responsible for some calculation functions, such as decoding and decoder. It is mainly responsible for processing the input signal and converting it into a format that the display screen can recognize.

[0031] In this embodiment of the present invention, the functional back plate 2 is connected to the back of the display screen body 1 via a smart buckle (not shown in the accompanying drawings). A support plate 3 is provided at the bottom of the functional back plate 2, which is essentially an integrally formed extension of the bottom of the functional back plate 2. The support plate 3 is positioned opposite to the back of the display screen body 1, and a gap 301 is reserved between the support plate 3 and the back of the display screen body 1. A fingerprint sensor 4 is provided on each side of the inner surface of the support plate 3. Maintenance personnel can insert both hands into the gap 301 and place their fingers on the fingerprint sensor 4 on the inner surface of the support plate 3 for fingerprint recognition. They can also support the bottom of the support plate 3 with their palms. When fingerprint recognition is successful, the functional back plate 2 can be directly lifted off the display screen body 1 with both hands, making the unlocking process convenient and quick. The fingerprint sensor 4 is electrically connected to the smart buckle. The fingerprint sensor and smart buckle in this embodiment of the present invention can adopt the fingerprint recognition unlocking principle of existing smart fingerprint locks, which will not be elaborated further here.

[0032] In this embodiment of the utility model, in order to make it easy for maintenance personnel to insert their fingers into the gap 301, the width of the gap between the tray 3 and the back of the display screen body 1 is 3-4cm.

[0033] In this embodiment of the invention, the fingerprint sensor 4 is placed on the inner surface of the tray 3 to make the maintenance unlocking device of the advertising screen more concealed than that of traditional advertising screens. To further increase the concealment of the maintenance device, making it difficult for non-management personnel to easily discover except for dedicated maintenance or management personnel, side baffles 302 are provided on both sides of the tray 3. The inner edge of the side baffle 302 is connected to the back of the display screen body 1, and the outer edge of the side baffle 302 is connected to the side edge of the tray 3. The two side baffles 302, the tray 3, and the back of the display screen body 1 enclose a fingerprint unlocking groove with an open bottom. The fingerprint sensor 4 of this invention is placed in the fingerprint unlocking groove. Only management personnel know the unlocking position. Non-management personnel cannot easily know the unlocking position of the maintenance device from the outside, thereby improving the security performance of the display screen and preventing the hardware and playback content of the display screen from being easily damaged or tampered with.

[0034] To accommodate the length of human fingers, the fingerprint unlocking slot is 6-8cm deep, ensuring that when a maintenance personnel's finger is placed on the surface of the fingerprint sensor 4, their palm rests precisely on the bottom of the support plate 3, facilitating the subsequent detachment of the functional backplate from the display screen body 1. Furthermore, the bottom of the support plate 3 does not extend beyond the bottom of the display screen body 1, allowing the fingerprint unlocking slot to be completely concealed behind the display screen body 1, further enhancing the concealment of the fingerprint sensor 4's installation position and thus strengthening the security of the unlocking device.

[0035] In this embodiment of the present invention, a pair of opposing fixing brackets 5 are provided on the back of the display screen body 1. The two fixing brackets 5 are arranged symmetrically in the longitudinal direction relative to the back of the display screen body 1. The functional back plate 2 is connected between the two fixing brackets 5 by the smart buckle. Further, the smart buckle includes a control circuit board 6, an actuator 7, and a pair of locking pins 8. The control circuit board 6 and the actuator 7 are disposed on one of the fixing brackets 5, and the two locking pins 8 are respectively disposed on the inner sides of the two fixing brackets 5, such as... Figure 5 As shown, the control circuit board 6 is electrically connected to the fingerprint sensor 4 and the actuator 7, respectively, and the actuator 7 is drivenly connected to the latch 8; the longitudinal edges on both sides of the functional back plate 2 are provided with slots 201 that cooperate with the latch 8. Figure 4 As shown, preferably, the locking pin 8 is an angled locking pin, and the locking groove 201 is a wedge-shaped locking groove, with the depth of the wedge-shaped locking groove gradually increasing from bottom to top. The combination of the angled locking pin and the wedge-shaped locking groove allows for dimensional correction, ensuring the proper installation position of the equipment. Figure 5 As shown, the unlocking principle of the smart buckle is as follows: when the control circuit board recognizes that the fingerprint electrical signal transmitted by the fingerprint sensor 4 meets the requirements, the control circuit board 6 controls the actuator 7 to act. The actuator 7 immediately drives the latch 8 to disengage from the slot, thereby completing the unlocking process. The control circuit board 6, actuator 7, and latch 8 mentioned above can all adopt existing technologies, and their circuit connection methods and control methods are common knowledge in the field. Therefore, those skilled in the art can achieve the above-mentioned technical means and effects based on the disclosure of this utility model and existing technology, without any physical or mental effort.

[0036] To prevent the functional backplate from suddenly falling off after unlocking, which could cause maintenance personnel to be unable to react in time and catch it, the smart buckle of this embodiment of the utility model further includes an elastic damper 9. The elastic damper 9 is connected between the fixing frame 5 and the longitudinal edge of the functional backplate 2. N elastic dampers 9 are provided, where N≥2 and N is an even number. The even number of elastic dampers 9 are evenly and symmetrically arranged between the fixing frame 5 and the functional backplate 2. The elastic damper 9 slows down the falling speed of the functional backplate 2, giving maintenance personnel time to react and catch it.

[0037] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
