[0029] See Figure 1 , this embodiment discloses a power supply device for an active power supply full-color price tag. The power supply device is used to provide the normal voltage required for the operation of the active power supply full-color price tag; the power supply device includes an aluminum profile 2, a guide rail 3, a positive conductive bar, and a negative conductive bar.

[0031] A power supply groove is formed in the lower part of the guide rail 3. The power supply groove includes a first conductive bar slot, a price tag slot, and a second conductive bar slot that are sequentially penetrated; wherein, the cross-sections of the first conductive bar slot, the price tag slot, and the second conductive bar slot are all rectangular, and partition bars are respectively extended at both ends of the side walls of the first conductive bar slot and the second conductive bar slot facing the price tag slot, so that the first conductive bar slot and the second conductive bar slot are in a semi-open shape, so that the positive conductive bar and the negative conductive bar are respectively inserted and installed in the first conductive bar slot and the second conductive bar slot.

[0032] A rotary interface is provided at the top end of the active power supply full-color price tag. A positive electrode elastic piece and a negative electrode elastic piece are respectively protrudingly provided on both sides of the rotary interface; the size of the rotary interface matches the size of the price tag slot. The rotary interface is inserted into the price tag slot and rotated 90 degrees under an external force, so that while the positive electrode elastic piece and the negative electrode elastic piece are clamped at the semi-open positions of the first conductive bar slot and the second conductive bar slot, they are respectively in contact and conduction with the positive conductive bar and the negative conductive bar in the first conductive bar slot and the second conductive bar slot.

[0033] In this embodiment, a 10.1-inch active power supply full-color price tag is taken as an example, as Figure 1 shown, including a price tag main body 1, conductive bars 4 (positive electrode bars and negative electrode bars), a guide rail 3, and an aluminum profile 2. As Figure 2 shown in (a) in, during the implementation operation, first make the front surface of the price tag main body 1 form a 90-degree angle with the cross-section of the guide rail 3, and the price tag main body 1 is inserted into the price tag slot of the guide rail 3 from bottom to top. After the elastic piece 102 on the price tag main body 1 completely enters the price tag slot of the guide rail 3, as Figure 2 shown in (b) in, the price tag main body 1 is rotated 90 degrees, so that the price tag main body 1 has no angle with the cross-section of the guide rail 3, and the elastic piece 102 on the price tag main body 1 contacts the conductive bar 4 inside the guide rail 3, and is respectively connected to the positive pole of the power input end and the negative pole of the power input end through the two conductive bars 4. The entire power supply device is easy to install and operate, has no requirements for the installation position of the price tag main body 1, and the price tag main body 1 can be suspended at any position on the guide rail, greatly improving the scene adaptability of the price tag main body 1.

[0034] As Figure 2As shown in the figure, the aluminum profile 2 can adopt the European standard 2020 aluminum profile. The cross-section of the aluminum profile 2 is square, and there is a notch on each of its four sides, with a total of four-direction notches 201. The notch 201 is in a semi-open shape. The notch part 301 of the guide rail 3 is two symmetrically arranged L-shaped hanging buckles, and the L-shaped hanging buckles are hung at the semi-open part of the notch 201, so that the guide rail 3 is fixed on the aluminum profile 2. Users can select the notch 201 in any direction according to actual needs, further improving the freedom of the installation position of the price tag main body 1.

[0035] There are two notch parts 301 on the guide rail 3. The aluminum profile 2 is inserted into the notch 301 on the aluminum profile for fixation. There are two slots 302 (the first conductive strip slot and the second conductive strip slot) under the guide rail 3. Two conductive strips 4 are inserted from the cross-section and fixed on the guide rail 3. The two conductive strips 4 are respectively connected to the positive and negative poles of the power input terminal.

[0036] As Figure 3 As shown in the figure, the price tag main body 1 includes two structures. The first structure is single-sided display: the price tag main body 1 is provided with a housing 103, a printed circuit board 104, a display screen 105, a front panel 106 and a rear panel 101; the housing 103 is in a rectangular frame structure, and a display screen step surface and a front panel step surface are provided at the front edge of the frame, and a rear panel step surface is provided at the rear edge of the frame; the printed circuit board 104 is fixed on the back of the display screen 105 by double-sided adhesive, the display screen 105 is fixed on the display screen step surface of the housing 103 by adhesive, and the front panel 106 and the rear panel 101 are respectively fixed on the front panel step surface and the rear panel step surface of the housing 103 by dotting process.

[0037] The second structure is double-sided display: by placing a printed circuit board 104, a display screen 105 and a front panel 106 in front of and behind the housing 103 respectively, it becomes double-sided display. Specifically, the active power supply full-color price tag includes a housing, a first printed circuit board, a second printed circuit board, a first display screen, a second display screen, a first panel and a second panel; the housing is in a rectangular frame structure, and a first display screen step surface and a first panel step surface are provided at the front edge of the frame, and a second display screen step surface and a second panel step surface are provided at the rear edge of the frame; the first printed circuit board is fixed on the back of the first display screen by double-sided adhesive, and the second printed circuit board is fixed on the back of the second display screen by double-sided adhesive; the first display screen and the second display screen are symmetrically arranged and are respectively fixed on the first display screen step surface and the second display screen step surface of the housing by adhesive; the first panel and the second panel are respectively fixed on the first panel step surface and the second panel step surface of the housing by dotting process.

[0038] The printed circuit board 104 is fixed to the back of the display screen 105 by double-sided adhesive. The display screen 105 is fixed to the outer shell 103 by gluing. The front panel 106 and the rear panel 101 are respectively fixed to the front and rear of the outer shell by the dispensing process. The front panel 106 is made of PC material and is used to protect the display screen 105.

[0039] Both the display screen 105 and the printed circuit board 104 are provided with FPC connectors and are connected by FPC. The outer shell 103 is the outer shell of the price tag. The elastic piece 102 is fixed to the outer shell 103 by insert molding, so that the elastic piece 102 can bear the weight of the price tag main body 1 itself without falling off during use.

[0040] The printed circuit board 104 is provided with a power connector and is connected to the elastic piece 102 by an electronic wire. When the price tag main body 1 is installed on the rail, the power supply is connected to the printed circuit board through the conductive bar 4, the elastic piece 102 and the electronic wire, so as to supply power to the printed circuit board. A rectifier bridge is provided on the printed circuit board. The power supply can be input without positive and negative polarities and output with fixed positive and negative polarities through the rectifier bridge, so that the price tag main body can be installed without direction during installation.

[0041] The conductive bar is thin and elastic. After the positive and negative elastic pieces rotate 90 degrees, they contact the conductive bar and apply a certain pressure to the conductive bar, causing the conductive bar to bend slightly in its respective receiving groove, ensuring that the positive and negative elastic pieces are in complete contact with the conductive bar without damaging the conductive bar. In this embodiment, multiple electronic price tags (such as more than 10) can be connected in series on one conductive bar.
