Description

Technical Field

[0001] This utility model relates to the technical field of power supply structure for cash register equipment, and in particular to an energy-saving power supply structure for information display equipment. Background Technology

[0002] In today's retail industry, point-of-sale (POS) devices are used very frequently as a key tool in the transaction process. With the rapid development of information technology, the functions of POS devices are becoming increasingly rich, and their information display capabilities are constantly improving, such as being equipped with customer operation screens (customer display screens) and cashier operation screens to provide a more intuitive and convenient interface for displaying transaction information and operating the device.

[0003] However, existing POS devices have some pressing issues regarding power supply structure and related technologies. Taking the integrated electronic POS device and method disclosed in Publication No. CN114627598A as an example, while the device structurally combines the main body with other components, the assembly of the main body and power supply components is not convenient. In practical applications, POS devices may require frequent disassembly and reassembly depending on different usage scenarios, store layouts, or equipment upgrade needs. If the assembly process is complex, it not only increases installation and maintenance time costs but may also damage the device during disassembly and reassembly, affecting its normal use and lifespan.

[0004] Furthermore, with the growing awareness of energy conservation and environmental protection, reducing the energy consumption of POS devices has become an important research direction. Most existing POS devices use fixed brightness settings or simple manual adjustments for screen brightness, failing to dynamically adjust based on ambient light levels and the proximity of users. For example, in dimly lit environments, excessively high screen brightness not only wastes energy but may also cause eye discomfort; conversely, when the device is unattended, the screen maintains high brightness, further exacerbating energy consumption. Utility Model Content

[0005] The purpose of this invention is to provide an energy-saving power supply structure for information display equipment. The T-shaped connecting block at the bottom of the POS device body is easily plugged into the connecting seat at the top of the power supply component. A spring force is used to engage the T-shaped locking pin on the side of the connecting seat with the slot on the side of the T-shaped connecting block, achieving convenient splicing of the two, simplifying installation and maintenance processes, and reducing costs and the risk of damage. Simultaneously, the photosensitive and infrared sensors on the customer display screen and the cashier's operating screen monitor ambient light and the proximity of people in real time. The built-in microcontroller unit in the power supply component dynamically adjusts the backlight driver chip based on sensor data, intelligently controlling screen brightness, thus reducing energy consumption, saving energy and protecting the environment, while also providing a comfortable user experience.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] An energy-saving power supply structure for an information display device includes:

[0008] A power supply component for energy-saving power supply of the main body of a POS device, wherein the main body of the POS device and the power supply component are fixedly connected by an installation component, wherein the installation component includes a T-shaped connecting block fixedly connected to the bottom of the main body of the POS device, and a connecting seat for cooperating with the T-shaped connecting block is fixedly connected to the top of the power supply component.

[0009] In the energy-saving power supply structure of the aforementioned information display device, both sides of the connecting seat are equipped with snap-fit ​​positioning components for fixing the T-shaped connecting block, and both sides of the T-shaped connecting block are provided with slots corresponding to the positions of the snap-fit ​​positioning components.

[0010] In the energy-saving power supply structure of the aforementioned information display device, the snap-fit ​​positioning component includes a mounting base fixedly connected to the side of the connecting seat, a T-shaped snap pin that matches the snap slot is slidably connected to the mounting base, a spring is fixedly connected to the T-shaped snap pin, and the other end of the spring is fixedly connected to the side of the mounting base.

[0011] The energy-saving power supply structure of the aforementioned information display equipment includes a customer display screen and a cashier operation screen installed on both sides of the main body of the POS equipment.

[0012] The energy-saving power supply structure of the aforementioned information display device includes a wire hole on the top of the power supply component, corresponding to the position of the main body of the POS device, and a protective rubber ring is provided on the inner wall of the wire hole.

[0013] The energy-saving power supply structure of the aforementioned information display equipment includes a microcontroller unit inside the power supply component, and photosensitive sensors and infrared sensors electrically connected to the microcontroller unit are installed on both the customer display screen and the cashier's operating screen.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. This utility model realizes an energy-saving power supply structure for information display equipment. The T-shaped connecting block at the bottom of the main body of the cash register device is conveniently plugged into the connecting seat at the top of the power supply component. The spring force is used to make the T-shaped locking pin on the side of the connecting seat snap into the slot on the side of the T-shaped connecting block, realizing convenient splicing of the two, simplifying the installation and maintenance process, and reducing costs and damage risks. At the same time, the photosensitive sensor and infrared sensor on the customer display screen and the cashier's operation screen monitor the ambient light and the proximity of people in real time. The microcontroller unit built into the power supply component dynamically adjusts the backlight driving chip according to the sensor data, intelligently controlling the screen brightness, which not only reduces energy consumption and saves energy and is environmentally friendly, but also provides users with a comfortable user experience.

[0016] 2. Convenient Assembly and Combination: This utility model achieves convenient plug-in connection between the main body of the POS device and the power supply component by setting a T-shaped connecting block at the bottom and a connecting seat at the top of the power supply component. During the plug-in process, the elastic force of the spring drives the T-shaped locking pin on the side of the connecting seat to engage with the slot on the side of the T-shaped connecting block, thereby quickly and stably completing the assembly. This convenient assembly method greatly simplifies the installation and maintenance process of the POS device, reduces the time and labor costs of installation and maintenance, and also reduces the potential damage risk to the equipment caused by complex disassembly and assembly processes, thereby improving the service life and reliability of the equipment.

[0017] 3. Intelligent Energy-Saving Adjustment: This invention incorporates a photosensitive sensor and an infrared sensor on both the customer display screen and the cashier's operating screen. The photosensitive sensor monitors the ambient light intensity in real time, while the infrared sensor detects whether anyone is approaching the device. The microcontroller unit built into the power supply component reads data from the photosensitive and infrared sensors on both the customer display screen and the cashier's operating screen via an ADC, and dynamically adjusts the backlight driver chips on both screens based on this data, thereby achieving intelligent control of screen brightness. For example, when the ambient light is dim, the microcontroller unit automatically reduces the screen brightness to avoid energy waste; when no one is detected approaching the device, the screen brightness also decreases accordingly, further saving energy. This intelligent energy-saving adjustment method not only significantly reduces the energy consumption of the POS equipment, aligning with the trend of energy conservation and environmental protection, but also provides users with a more comfortable experience, reducing discomfort caused by excessively high or low screen brightness.

[0032] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0033] Please refer to Figures 1 to 5 As shown, an embodiment of this utility model provides an energy-saving power supply structure for an information display device, including: a power supply component 2 for energy-saving power supply to the main body 1 of the cash register device, the main body 1 of the cash register device and the power supply component 2 are fixedly connected by an installation component 3, the installation component 3 includes a T-shaped connecting block 301 fixedly connected to the bottom of the main body 1 of the cash register device, and a connecting seat 3011 that cooperates with the T-shaped connecting block 301 is fixedly connected to the top of the power supply component 2;

[0034] By adopting the above technical solution, the T-shaped connecting block 301 at the bottom of the main body 1 of the cash register device is conveniently plugged into the top connecting seat 3011 of the power supply component 2. The spring force 3032 is used to make the T-shaped locking pin 3031 on the side of the connecting seat 3011 snap into the slot 3021 on the side of the T-shaped connecting block 301, so as to achieve convenient splicing of the two, simplify the installation and maintenance process, and reduce costs and damage risks. At the same time, the photosensitive sensor 2021 and infrared sensor 2022 on the customer display screen 101 and the cashier operation screen 1011 monitor the ambient light and the proximity of people in real time. The microcontroller unit 202 built into the power supply component 2 dynamically adjusts the backlight driving chip according to the sensor data, and intelligently controls the screen brightness, which not only reduces energy consumption and saves energy and protects the environment, but also provides users with a comfortable user experience.

[0035] To ensure the stability of the connection between the main body 1 of the POS device and the power supply component 2, in this embodiment: both sides of the connecting seat 3011 are equipped with snap-fit ​​positioning components 302 for fixing the T-shaped connecting block 301. Both sides of the T-shaped connecting block 301 and the corresponding positions of the snap-fit ​​positioning components 302 are provided with slots 3021. The cooperative design of the snap-fit ​​positioning components 302 and the slots 3021 provides a reliable fixing mechanism for the connection between the main body 1 of the POS device and the power supply component 2.

[0036] To achieve a convenient and reliable snap-fit ​​fixing function, in this embodiment: the snap-fit ​​positioning component 302 includes a mounting base 303 fixedly connected to the side of the connecting base 3011. A T-shaped snap pin 3031 matching the snap slot 3021 is slidably connected to the mounting base 303. A spring 3032 is fixedly connected to the T-shaped snap pin 3031. The other end of the spring 3032 is fixedly connected to the side of the mounting base 303. The combination design of the T-shaped snap pin 3031 and the spring 3032 enables the snap-fit ​​positioning component 302 to have automatic snap-fit ​​and reset functions. During the splicing process, the T-shaped snap pin 3031 will slide and compress the spring 3032 when it is squeezed. When it reaches the position of the snap slot 3021, the elastic force of the spring 3032 will push the T-shaped snap pin 3031 into the snap slot 3021, realizing convenient snap-fit. During disassembly, only a certain external force needs to be applied to make the T-shaped snap pin 3031 overcome the elastic force of the spring 3032 and slide out of the snap slot 3021. This design not only simplifies the splicing and disassembly operations, but also ensures the reliability and stability of the snap-fit ​​connection, improving the ease of use of the equipment.

[0037] To meet the information display and operation requirements of the POS equipment, in this embodiment: a customer display screen 101 and a cashier operation screen 1011 are respectively installed on both sides of the main body 1 of the POS equipment. The setup of the customer display screen 101 and the cashier operation screen 1011 provides a clear and intuitive information display and operation interface for the checkout process. The customer display screen 101 faces the customer and can display transaction information in real time, such as product price and total amount, making it convenient for customers to understand the transaction details; the cashier operation screen 1011 is for cashiers to operate, such as inputting product information and selecting payment methods, which improves checkout efficiency, reduces human error, and provides strong support for efficient and accurate checkout transactions.

[0038] To protect the connecting lines and ensure the cleanliness of the internal components of the device, in this embodiment, a wire-passing hole 201 is provided on the top of the power supply component 2, corresponding to the position of the main body 1 of the POS device. A protective rubber ring 2011 is provided on the inner wall of the wire-passing hole 201. The wire-passing hole 201 provides a channel for the connecting lines between the main body 1 of the POS device and the power supply component 2, allowing the lines to pass through neatly and orderly, avoiding a messy distribution of lines inside the device. This not only ensures the aesthetics and cleanliness of the internal components but also facilitates the installation and maintenance of the lines. The protective rubber ring 2011 further protects the connecting lines, preventing them from being worn or scratched when passing through the wire-passing hole 201, extending the service life of the lines, and improving the reliability of the device operation.

[0039] To achieve intelligent screen brightness adjustment for energy saving, in this embodiment: a microcontroller unit 202 is internally installed in the power supply component 2. Both the customer display screen 101 and the cashier's operating screen 1011 are equipped with photosensitive sensors 2021 and infrared sensors 2022, which are electrically connected to the microcontroller unit 202. The microcontroller unit 202, as the core of intelligent adjustment, is electrically connected to the photosensitive sensors 2021 and 2022, enabling it to acquire real-time ambient light intensity and the proximity of people. The photosensitive sensor 2021 detects ambient light, and the infrared sensor 2022 detects the proximity of people. Based on this data, the microcontroller unit 202 dynamically adjusts the backlight driver chips on the customer display screen 101 and the cashier's operating screen 1011, thereby intelligently controlling the screen brightness. This intelligent adjustment method can reasonably adjust the screen brightness according to actual usage, avoiding energy waste and achieving energy saving, while also providing users with a more comfortable user experience.

[0040] The working principle of this utility model is as follows:

[0041] When assembling the main body 1 of the POS terminal and the power supply component 2, the T-shaped connecting block 301 at the bottom of the main body 1 is easily inserted into the connecting seat 3011 at the top of the power supply component 2. During the insertion process, the T-shaped locking pin 3031 on the side mounting base 303 of the connecting seat 3011 slides under the pressure of the T-shaped connecting block 301, compressing the spring 3032 connected to it. When the T-shaped locking pin 3031 reaches the position of the slot 3021 on the side of the T-shaped connecting block 301, the elastic force of the spring 3032 pushes the T-shaped locking pin 3031 into the slot 3021, thereby realizing the convenient assembly of the main body 1 of the POS terminal and the power supply component 2, and ensuring the stability of the assembled device structure.

[0042] Meanwhile, the photosensitive sensor 2021 and infrared sensor 2022 installed on the customer display screen 101 and the cashier operation screen 1011 monitor the ambient light intensity and the proximity of people in real time. The microcontroller unit 202 inside the power supply component 2 reads the data from these sensors through an ADC and dynamically adjusts the backlight driver chip on the customer display screen 101 and the cashier operation screen 1011 according to the data, thereby controlling the screen brightness. For example, when the ambient light is dim, the microcontroller unit 202 will automatically reduce the screen brightness to avoid energy waste; when no one is detected approaching the device, the screen brightness will also be reduced accordingly, further saving energy. Through this intelligent adjustment of screen brightness, this invention achieves the goal of energy saving and environmental protection while meeting the normal use requirements of the POS equipment, providing users with a more efficient and energy-saving POS solution.
