[0043] In order to have a clearer understanding of the technical features, objectives and effects of the present application, the specific embodiments of the present application will be described with reference to the accompanying drawings.

[0044] As shown in Figures 1 to 3 The present application provides an electronic price tag, which comprises a rear shell 1, a screen 4, a protective sleeve 5 and a lens 6, wherein: the protective sleeve 5 is fixedly sleeved outside the screen 4, the rear shell 1 is formed with an accommodating groove 101, the screen 4 and the protective sleeve 5 are fixedly arranged in the accommodating groove 101, the lens 6 is arranged at the slot opening of the accommodating groove 101 and connected with the edge of the rear shell 1, and the protective sleeve 5 at the display opening edge of the screen 4 is supported between the lens 6 and the screen 4, so that a pressure gap 8 is reserved between the lens 6 and the screen 4.

[0045] In the present application, the protective sleeve 5 is sleeved outside the screen 4, which can protect the whole screen 4 (i.e. the six end faces of the screen), when the screen 4 is subjected to external force from any direction, the protective sleeve 5 will deform itself to play a buffering and shock-absorbing role, thereby achieving the protection of the screen; in addition, since the pressure gap 8 is reserved between the lens 6 and the screen 4, even if the lens 6 is subjected to external pressure, the lens 6 will deform in the pressure gap 8 area and will not directly press the screen 4, which can effectively avoid the damage of the screen 4 due to extrusion, play a protective role for the screen 4, and further improve the anti-impact and anti-extrusion ability of the electronic label, prolong the service life of the electronic label.

[0046] Further, the protective sleeve 5 can be made of, but not limited to, a flexible silicone material.

[0047] Further, the protective sleeve 5 is provided with a display window 501 at a position opposite to the display port of the screen 4, and the lens 6 is made of transparent material, so that the screen 4 can display the commodity information to the outside through the display window 501 and the lens 6 in turn.

[0048] In the present application, as shown in Figure 1 、 Figures 3 to 5 , the electronic tag further comprises a battery 2 and a circuit board 3, both of which are fixedly arranged in the accommodating groove 101, and the circuit board 3 is connected with the rear shell 1, so that the tab 201 of the battery 2 is pressed against the power supply end of the circuit board 3.

[0049] In an optional embodiment of the present application, as shown in Figure 1 、 Figure 4 , the circuit board 3 is provided with a fixing hole 301, and a screw 7 is arranged in the fixing hole 301, so that the circuit board 3 is fastened and connected with the rear shell 1 through the screw 7, thereby ensuring the stability of power supply.

[0050] In another optional embodiment of the present application, as shown in Figure 5 , the tab 201 of the battery 2 is welded with the power supply end of the circuit board 3, so that the tab 201 of the battery 2 and the power supply end of the circuit board 3 maintain a fixed connection relationship, thereby ensuring the stability of power supply.

[0051] Further, the battery 2 is externally covered with an aluminum-plastic film shell.

[0052] Further, the battery 2 adopts a lithium-manganese soft-pack battery, which can greatly enhance the following application performance indicators on the basis of ensuring good safety, high cost performance and other advantages.

[0053] I. Customizable appearance; the appearance can be customized according to the installation space to meet the needs of products;

[0054] II. Equivalent self-discharge rate: the average annual self-discharge rate of the electronic price tag is less than 1% during long-term use;

[0055] III. Good storage performance: the storage life is more than ten years;

[0056] IV. Wide temperature performance: the applicable temperature range is-25℃ to 60℃, and the output of the battery at 0℃ is still about 95% of the normal temperature capacity;

[0057] V. Current load capacity: the constant current output capacity is more than 100mhA, which is more than 10 times of that of a CR2450 button lithium manganese dioxide battery.

[0058] In an optional embodiment of the present application, as shown in Figure 4As shown, multiple snap-fit ​​pieces 1011 are arranged side by side and spaced apart on the inner wall of the receiving groove 101. The battery 2 is located in the middle of each snap-fit ​​piece 1011, and the edge of the battery 2 is engaged with each snap-fit ​​piece 1011. This not only makes disassembly and assembly convenient, but also ensures that the battery 2 is stably installed in the rear shell 1.

[0059] In an optional embodiment of the present invention, such as Figures 6 to 8 As shown, both the circuit board 3 and the back cover 1 are rectangular structures. The circuit board 3 can be installed in one of the top corners of the back cover 1, so that the shape of the circuit board 3 can be matched with the back cover 1 of various sizes. The circuit board 3 has high versatility and is suitable for modular production, which can achieve the purpose of rapid inventory preparation, mass production and reduced processing costs.

[0060] In the prior art, the screen is fixed and protected by connecting the circuit board to the screen. However, since the shape of the circuit board 3 in this invention is suitable for modular production, the area of ​​the circuit board 3 in this invention needs to be much smaller than that of the circuit board in the prior art. Therefore, the circuit board 3 cannot fix and protect the screen 4 in this invention. In order to ensure that the screen 4 is not damaged, a protective sleeve 5 is provided in this invention to protect the screen 4.

[0061] In an optional embodiment of the present invention, the connection between the lens 6 and the rear shell 1 can be achieved by ultrasonic welding. For example... Figure 9 , Figure 10 As shown, a welding groove 102 is provided along the edge of the rear shell 1. An inclined surface 1021 is formed on the inner wall of the welding groove 102 along its extending direction. The cross-section of the edge of the lens 6 is right-angled. The edge of the lens 6 is placed within the welding groove 102, and the edge of the lens 6 is ultrasonically welded to the inner wall of the welding groove 102, so that the rear shell 1 and the lens 6 form an integral structure. During the installation of the lens 6, as... Figure 9 As shown, the lens 6 needs to be placed in the welding groove 102 until the edge of the lens 6 abuts against the inclined surface 1021. While continuing to press the lens 6, ultrasonic welding is performed between the lens 6 and the inner wall of the welding groove 102. During the welding process, a compressive force is generated between the inclined surface 1021 and the edge of the lens 6, causing the inclined surface 1021 to melt and fill the remaining gap between the lens 6 and the welding groove 102. This allows the edge of the lens 6 to fit into the welding groove 102, achieving a stable connection between the lens 6 and the back shell 1. Of course, other structures can also be provided in the welding groove 102 so that before the lens 6 is connected to the back shell 1, the edge of the lens 6 does not fit into the inner wall of the welding groove 102 (i.e., the cross-section of the welding groove 102 is not a right angle), ensuring that the inner wall of the welding groove 102 can fit into the edge of the lens 6 during ultrasonic welding.

[0062] In another optional embodiment of the present application, the connection between the lens 6 and the rear shell 1 can adopt point bonding, a welding groove 102 is arranged at the edge position of the rear shell 1, the cross section of the welding groove 102 and the cross section of the edge of the lens 6 are both right angles, so that the edge of the lens 6 is not matched with the inner wall of the welding groove 102, the edge of the lens 6 is arranged in the welding groove 102, and the edge of the lens 6 is point bonded with the inner wall of the welding groove 102.

[0063] In an optional embodiment of the present application, as shown in Figures 1 to 4 The edge position of the rear shell 1 is provided with a sticker 9, which can be used for marking a bar code, so as to bind the electronic price tag with the commodity through the bar code, and ensure that the information of the electronic price tag is consistent with the commodity information.

[0064] The electronic price tag has the following characteristics and advantages:

[0065] I. The electronic price tag can protect the six end faces of the screen 4 through the protective sleeve 5, when subjected to external force in various directions, the protective sleeve 5 will deform itself to play a buffering and shock absorbing role, thereby achieving the purpose of protecting the screen 4.

[0066] II. The electronic price tag reserves a pressure prevention gap 8 between the lens 6 and the screen 4, even if the lens 6 is subjected to external extrusion force, the lens 6 will deform in the pressure prevention gap 8 area, and will not directly extrude the screen 4, effectively avoiding damage to the screen 4 due to extrusion, playing a protective role for the screen 4, improving the anti-impact and anti-extrusion ability of the electronic label, and prolonging the service life of the electronic label.

[0067] III. The circuit board 3 in the electronic price tag can be matched with rear shells 1 of various sizes, has high universality, is suitable for modular production, can achieve the purposes of rapid stocking, batch production and reducing processing cost.

[0068] IV. The circuit board 3 and the battery 2 in the electronic price tag can be fixed through various connection modes, which is convenient to install and has high stability.

[0069] V. The electronic price tag adopts a lithium-manganese soft package battery as a power supply, which not only occupies small space, but also has the advantages of good safety, high cost performance, etc., and has more excellent performance indicators compared with a button cell.

[0070] VI. In the electronic price tag, since a lithium-manganese soft package battery is adopted, the thickness is greatly reduced, and under the condition of the same electric quantity, the electronic price tag of the present application can meet the size requirement of ultra-thin appearance.

[0071] The above merely illustrates the specific embodiments of the present application, and is not used to limit the scope of the present application. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present application shall fall within the scope of the present application.
