Description

Technical Field

[0001] This utility model relates to the field of advertising placement equipment technology, and in particular to an advertising machine. Background Technology

[0002] With the continuous development of modern technology, commercial LCD advertising machines are ubiquitous, such as bank window displays and subway arrival displays. The emergence of commercial LCD advertising machines has significantly changed the traditional display model, evolving traditional poster displays into intelligent commercial LCD advertising machines. In addition, commercial LCD advertising machines are also found in supermarkets, shopping malls, bus stops, etc., such as shopping mall window advertising machines and merchandise counter advertising machines, widely used in banks, subways (high-speed rail), and other high-traffic areas, serving as intelligent devices for various business transactions. However, when advertising machines are installed outdoors in areas with strong sunlight, the brightness of the display does not match the ambient brightness. In high ambient brightness, high display brightness wastes energy, while low display brightness makes the display difficult to see; conversely, in low ambient brightness, high display brightness is glaring and strains the eyes, while low display brightness makes it even more difficult to see.

[0003] Existing outdoor advertising displays can control screen brightness by adjusting the current of the constant current board based on the ambient light level. However, the maximum backlight brightness of these displays is generally limited to 2500 lumens and is not adjustable. Excessive backlight brightness can cause the device to overheat, affecting its performance and lifespan. Some displays adjust the constant current by modifying resistors on the backlight's constant current board, a cumbersome and inefficient method. Utility Model Content

[0004] In order to address the technical deficiencies mentioned in the background section, the purpose of this utility model is to provide an advertising machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An advertising machine includes a power supply component, a motherboard, a constant current board, a display screen component, and a backlight component; the power supply component is electrically connected to the motherboard and the backlight component; the motherboard is electrically connected to the constant current board, and the constant current board is electrically connected to the backlight component to provide a stable DC current; the motherboard is communicatively connected to the display screen component; it also includes a modulator and a light sensor component; the modulator is electrically connected between the light sensor component and the constant current board, the light sensor component is used to sense the brightness of the surrounding environment to control the constant current board to adjust the output current, and the modulator is used to adjust the input voltage of the constant current board to regulate the output DC current of the constant current board.

[0007] By adopting the above technical solution, users can manually select the appropriate setting on the modulator according to the actual situation on site to adjust the maximum backlight intensity of the backlight assembly. This reduces excessive heat generation caused by overly bright display components, improves the working performance of the advertising machine, and extends the service life of various components. Moreover, the modulator is very convenient to adjust, simple to operate, has a wide adjustable range, and is more compatible.

[0008] Furthermore, the advertising machine includes a back panel and a front cover. The back panel and the front cover form an internally hollow box structure.

[0009] Furthermore, the modulator is disposed between the photosensitive component and the constant current plate, and the constant current plate is disposed at the end of the back plate away from the photosensitive component, resulting in a compact structure and reasonable layout.

[0010] Furthermore, the main board is located on one side of the constant current board, and a square protective cover is provided on the main board. The knob end of the modulator is located outside the protective cover for easier adjustment. The other end of the modulator passes through the protective cover and is located above the main board for easy installation and connection of circuits, improving assembly efficiency, saving costs, and also serving to protect and seal components.

[0011] Furthermore, the light-sensing assembly includes a mounting base and a light-sensing element. The mounting base is a box-shaped structure with an opening on one side. Two clearance slots on one side of the mounting base allow the light-sensing element to pass through. The light-sensing element is fixed to the mounting base with screws, facilitating installation, providing good protection, and extending service life. The end caps at both ends of the mounting base are bent outwards into an L-shape to connect and fix to the inner wall of the front cover, allowing the probe of the light-sensing element to pass through the fixing slot, thereby improving feedback and adjustment efficiency.

[0012] Furthermore, the modulators are all electrically connected to the photosensitive component and the constant current plate via wires, resulting in a more stable structural connection.

[0013] In summary, the beneficial effects of this utility model are as follows:

[0014] This invention allows users to manually select the appropriate setting on the modulator knob according to the actual situation, thereby adjusting the maximum backlight intensity of the backlight assembly. This reduces excessive heat generation caused by overly bright display components, improves the performance of the advertising machine, and extends the service life of various components. Furthermore, the modulator is very convenient to adjust, simple to operate, has a wide adjustable range, and offers enhanced compatibility. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-5 The embodiments of this utility model will be described in further detail below.

[0026] An advertising machine 1, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes a power supply assembly 10, a motherboard 2, a constant current board 3, a display assembly 4, a backlight assembly 11, a modulator 5, and a light sensor 6. The power supply assembly 10 is electrically connected to the motherboard 2 and the backlight assembly 11. The motherboard 2 is electrically connected to the constant current board 3, which is in turn electrically connected to the backlight assembly 11 to provide a stable DC current. The motherboard 2 is communicatively connected to the display assembly 4. The modulator 5 is electrically connected between the light sensor 6 and the constant current board 3. The light sensor 6 senses the ambient brightness to control the constant current board 3 and adjusts its output current. The modulator 5 adjusts the input voltage of the constant current board 3 to regulate its output DC current.

[0027] Users can manually rotate the modulator 5 to select the appropriate setting to adjust the maximum backlight intensity of the backlight assembly 11 according to the actual situation on site. This reduces excessive heat generation caused by overly bright display components 4, improves the working performance of the advertising machine 1, and extends the service life of each component. Moreover, the modulator 5 is very convenient to adjust, simple to operate, has a wide adjustable range, and is more compatible.

[0028] In some embodiments, please refer to Figure 1 , Figure 3 The advertising machine 1 includes a back panel 7 and a front cover 8. The back panel 7 and the front cover 8 form a hollow box structure. The front cover 8 has an installation window on the side away from the back panel 7 for installing the backlight assembly 11 and the display screen assembly 4. A fixing groove for installing the light sensor assembly 6 is provided on one side of the installation window, which helps to improve the sensitivity of the sensing environment and facilitates timely adjustment of the backlight brightness.

[0029] In some embodiments, please refer to Figure 3 , Figure 4 The modulator 5 is located between the light sensor 6 and the constant current plate 3. The constant current plate 3 is located at the end of the back plate 7 away from the light sensor 6. The structure is compact and the layout is reasonable.

[0030] Preferably, the modulators 5 are all electrically connected to the photosensitive component 6 and the constant current plate 3 via wires, resulting in a more stable structural connection.

[0031] Specifically, the main board 2 is located on one side of the constant current board 3. A square protective cover 9 is provided on the main board 2. The knob end of the modulator 5 is located outside the protective cover 9, making adjustment more convenient. The other end of the modulator 5 passes through the protective cover 9 and is located above the main board 2, which facilitates the installation and connection of circuits, improves assembly efficiency, saves costs, and can also play a role in protecting and sealing components.

[0032] In some embodiments, please refer to Figure 3 , Figure 4 The light-sensing assembly 6 includes a mounting base 61 and a light-sensing element 62. The mounting base 61 is a box-shaped structure with an opening on one side. Two clearance slots are provided on one side of the mounting base 61 for the light-sensing element 62 to see through. The light-sensing element 62 is fixed inside the mounting base 61 with screws, which facilitates installation, provides good protection, and extends service life. The end caps 611 at both ends of the mounting base 61 are bent outwards into an L-shape to be connected and fixed to the inner wall of the front cover 8, which facilitates the insertion of the probe of the light-sensing element 62 through the fixing slot, thereby improving the efficiency of feedback and adjustment.

[0033] During debugging, simply opening the front cover 8 allows rotation to adjust the modulator 5's settings. Different settings correspond to different power values, thus regulating the input voltage of the constant current plate 3 in the circuit. This, in turn, controls the output current of the constant current plate 3, ultimately adjusting the maximum backlight brightness of the backlight assembly 11. The entire process is simple to operate, highly efficient, and highly controllable, making it compatible with various applications.

[0034] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
