Description

Technical Field

[0001] This utility model relates to the field of electronic price tag back panels, and more particularly to an electronic price tag back panel that can be displayed horizontally or vertically. Background Technology

[0002] Electronic shelf labels (ESCs), as a modern commercial information display tool, typically consist of an electronic display screen, internal electronic components, and an interface for communication with external systems. Their main function is to display product prices, promotional information, and inventory status. They are widely used in supermarkets, convenience stores, pharmacies, and other retail establishments, providing customers with clear and real-time product information while also facilitating price management and inventory updates for retailers.

[0003] In existing technologies, there are various methods for fixing electronic shelf labels. One common method is to use clips or clamps to secure the electronic shelf labels to the edge of the shelf or a special bracket. These clips or clamps are usually designed to match the shape of the electronic shelf label, ensuring stable fixation through elastic deformation or mechanical locking. However, this method often requires disassembling the entire shelf label when the display orientation needs to be adjusted, which is rather cumbersome.

[0004] In scenarios where a single back panel is supported by a bracket or suspension, existing technologies typically employ a fixed connection structure. For example, some back panels are fixed to a bracket with screws or rivets, or connected to a suspension via specialized hooks or slots, and then the electronic shelf label is inserted into the back panel, which is already locked in either a horizontal or vertical orientation. While these structures can stably support the back panel, they do not allow for adjustment of the back panel's orientation, i.e., the display direction of the electronic shelf label cannot be adjusted, which is inconvenient. Utility Model Content

[0005] Therefore, there is a need to provide an electronic price tag backplate that can be displayed both horizontally and vertically, to solve the problem that although the existing technology can stably support the backplate, it cannot adjust the orientation of the backplate, that is, it cannot adjust the display orientation of the electronic price tag, which is quite inconvenient.

[0006] To achieve the above objectives, this utility model provides an electronic price tag back panel that can be displayed horizontally or vertically, including a back panel body. The front of the back panel body is provided with a price tag fixing mechanism, which is used to detachably connect and fix the electronic price tag. The back of the back panel body is provided with a back panel fixing mechanism, which is used to cooperate with an external fixing frame for fixed connection. The back panel fixing mechanism includes two installation directions: horizontal and vertical. By switching the installation direction through the back panel fixing mechanism, the display position can be switched between horizontal and vertical.

[0007] Furthermore, the back plate fixing mechanism is a circular boss that protrudes to the rear, and the annular wall of the boss is provided with multiple protruding strips parallel to the boss surface.

[0008] Furthermore, the number of the protrusions is four, and the four protrusions are arranged coplanarly with equal spacing.

[0009] Furthermore, the boss has multiple protrusions on its surface.

[0010] Furthermore, the platform of the protrusion is provided with multiple annular openings, and each of the multiple openings is provided with an elastic strip, and the multiple protrusions are respectively provided on the upper surface of the multiple elastic strips.

[0011] Furthermore, it also includes an adapter, which includes a sleeve and a connecting part. The sleeve has a circular groove structure and multiple slide rails and multiple circular holes inside. When the sleeve is sleeved with the boss, the multiple protrusions slide into the multiple slide rails for fixation and the multiple protrusions are embedded in the multiple circular holes by rotating the sleeve. The connecting part is used to connect and fix with an external fixing frame.

[0012] Furthermore, one end of the slide rail is closed, and the width of the slide rail gradually narrows from the open side to the closed side.

[0013] Furthermore, two sockets are provided symmetrically back to back, and the connecting part is provided on the side of the socket.

[0014] Furthermore, it also includes a cover plate, which is disposed on the sleeve portion of the adapter.

[0015] Furthermore, the backplate fixing mechanism is located at the center of the back of the backplate body.

[0016] Unlike existing technologies, the above technical solution includes a back panel body. The front of the back panel body is provided with a price tag fixing mechanism, which is used to detachably connect and fix electronic price tags. The back of the back panel body is provided with a back panel fixing mechanism, which is used to cooperate with an external fixing frame for fixed connection. The back panel fixing mechanism includes two installation directions: horizontal and vertical. By switching the installation direction through the back panel fixing mechanism, the display position can be switched between horizontal and vertical. Users can quickly adjust the display direction of the electronic price tags according to actual needs, improving the flexibility and practicality of the back panel. Attached Figure Description

[0040] Please see Figures 1 to 12 This embodiment provides an electronic price tag back panel that can be displayed horizontally or vertically, including a back panel body 10. The front of the back panel body 10 is provided with a price tag fixing mechanism 20, which is used to detachably connect and fix to an electronic price tag 60. The back of the back panel body 10 is provided with a back panel fixing mechanism 30, which is used to cooperate with an external fixing frame 70 for fixed connection. The back panel fixing mechanism 30 includes two installation directions, horizontal and vertical. By switching the installation direction through the back panel fixing mechanism 30, the display position can be switched between horizontal and vertical.

[0041] The back panel body 10, the price tag fixing mechanism 20, and the back panel fixing mechanism 30 are all made of plastic, such as PC (polycarbonate). PC material has good mechanical strength, impact resistance, and transparency, which can effectively protect the electronic price tag from external physical damage, while ensuring the lightweight and durability of the back panel body 10. In addition, PC material also has good insulation properties and will not interfere with the signal transmission of the electronic price tag.

[0042] Electronic shelf labels come in various sizes, and the back panel body 10 can be adapted to electronic shelf labels of different sizes. For example, the back panel body 10 can be used to adapt to 13.3-inch electronic shelf labels. By adjusting the size and shape of the back panel body 10, usage needs in different scenarios can be met.

[0043] The price tag fixing mechanism 20 can have several specific structures. One type involves setting slide rails 4011 along the upper and lower edges or left and right edges of the back panel body 10, and using a locking structure to fix the electronic price tag. The slide rails 4011 allow the electronic price tag to be inserted or removed along the slide rails 4011, while the locking structure ensures that the electronic price tag will not loosen during use. Another type involves setting clips at the four corners of the back panel body 10, which are used to snap and fix the electronic price tag. The clips allow for quick installation and removal of the electronic price tag, improving the ease of operation.

[0044] The specific structure of the back panel fixing mechanism 30 can refer to existing price tag guide rail structures. For example, the back panel fixing mechanism 30 can be snapped into the shelf rail, or connected to the external fixing frame using a slide rail 4011 groove structure, or connected to the external fixing frame using a screw threaded cylinder structure. These structures allow the back panel fixing mechanism 30 to be flexibly fixed to the external fixing frame, while allowing the back panel body 10 to switch between horizontal and vertical display positions.

[0045] The installation direction switching mechanism of the back panel fixing mechanism 30 is as follows: When it is necessary to switch the back panel body 10 from the horizontal display position to the vertical display position, simply remove the back panel fixing mechanism 30 from the external fixing frame, rotate it 90 degrees, and reinstall it; the reverse is also true. Users can quickly adjust the display direction of the electronic shelf label according to actual needs, improving the flexibility and practicality of the back panel. The definitions of horizontal and vertical display positions are as follows: Electronic shelf labels are usually rectangular. When the long side is horizontal, it is in the horizontal display position, which is convenient for displaying text information, such as product names; when the long side is vertical, it is in the vertical display position, which is convenient for displaying image information, such as sales posters.

[0046] In some embodiments, the back panel fixing mechanism 30 is a rearward-protruding circular boss 301, with multiple protruding strips 302 parallel to the boss's surface on its annular wall. The circular boss 301 has a hollow structure and a certain wall thickness, which ensures structural strength while reducing the overall weight of the back panel and lowering costs. By setting the back panel fixing mechanism 30 as a circular boss 301 structure and providing protruding strips 302 on the annular wall of the circular boss 301, the installation direction of the back panel body 10 can be directly adjusted by rotating 90 degrees, flexibly switching between horizontal and vertical display positions. The external fixing frame can be equipped with a matching connecting mechanism, such as a circular fixing groove with a slide rail 4011 on the inner wall of the groove. The slide rail 4011 needs to have openings for the protruding strips 302 to be pushed in. By inserting the circular boss 301 into the fixing groove, allowing the protrusion 302 to enter the inner side of the slide rail 4011, and then rotating it 90 degrees, the slide rail 4011 restricts the protrusion 302 to the inner side, thus achieving fixation. This simple 90-degree rotation allows for quick adjustment of the display direction of the back panel body 10, improving operational convenience and flexibility. Preferably, there are four protrusions 302, which are equally spaced and coplanar. This ensures that the back panel body 10 is evenly stressed during the 90-degree rotation, guaranteeing a smooth and seamless transition between horizontal and vertical display positions. The equally spaced protrusions 302 also provide a more stable fixation effect, ensuring that the back panel body 10 will not loosen or shift due to external forces during use. This structure not only improves the stability and reliability of the back panel but also enhances its adaptability to different display directions.

[0047] In some embodiments, the platform of the boss is provided with multiple protrusions 303. These protrusions 303 further improve the stability of the back panel. On the external fixing bracket that cooperates with the back panel fixing mechanism 30, corresponding locking holes are provided at the contact points to accommodate the protrusions 303. When the back panel fixing mechanism 30 is switched to a horizontal or vertical display position, the protrusions 303 are precisely engaged in the locking holes, thereby further locking the position of the back panel body 10 and preventing it from shaking or shifting during use. The protrusions 303 can be made of hard plastic or rubber with a certain degree of frictional resistance. Hard plastic protrusions 303 have good wear resistance and strength, and can withstand frequent installation and disassembly operations; rubber protrusions 303 have a certain degree of elasticity, providing better frictional resistance and further enhancing the fixing effect of the back panel. This ensures that the back panel remains stable under different display orientations, improving its reliability and practicality in actual use.

[0048] In some embodiments, the platform of the boss has multiple annular openings, each containing an elastic strip 304, and multiple protrusions 303 are correspondingly disposed on the upper surface of the elastic strips 304. The elasticity of the elastic strips 304 allows the round boss 301 to push open the protrusions 303 during connection, preventing the protrusions 303 from obstructing the round boss 301 from entering the connection fixing groove. This also prevents the protrusions 302 from failing to enter the inner side of the slide rail 4011. After the round boss 301 rotates 90 degrees to the back panel body 10 in either a horizontal or vertical display position, the elastic strips 304 return to their original position, at which point the protrusions 303 can be precisely inserted into the locking holes. This not only improves the stability of the back panel body 10 but also ensures ease of operation when switching display directions. The elastic strips 304 allow the protrusions 303 to automatically adjust their position during connection, reducing operation steps and improving installation efficiency. Meanwhile, the restoring force of the elastic strip 304 ensures the stable embedding of the protrusion 303 in its final position, further enhancing the fixing effect of the back panel body 10.

[0049] See Figure 10 In some embodiments, an adapter 40 is also included. The adapter 40 includes a sleeve portion 401 and a connecting portion 402. The sleeve portion 401 has a circular groove structure, and its interior is provided with multiple slide rails 4011 and multiple circular holes 4012. When the sleeve portion 401 is sleeved with the boss, rotating the sleeve portion 401 by 90 degrees causes multiple protrusions 302 to slide into the multiple slide rails 4011 for fixation, and multiple protrusions 303 to embed into the multiple circular holes 4012. The connecting portion 402 is used to connect and fix with the external fixing frame. By providing the adapter 40, the adapter 40 can be connected to the back plate fixing mechanism 30 separately first, and then fixedly connected to the external fixing frame through the adapter 40, which is convenient for operation. The connecting portion 402 can adopt various connection structures in the prior art, such as a simple sleeve plug connection. This not only improves installation flexibility but also allows users to choose the appropriate connection method based on different external mounting brackets, enhancing the versatility and adaptability of the backplate.

[0050] In some embodiments, one end of the slide rail 4011 is closed, and the width of the slide rail 4011 gradually narrows from the open side to the closed side. This allows the narrowest point of the slide rail 4011 to form an interference fit with the protrusion 302, and when the protrusion 302 reaches the narrowest point of the slide rail 4011, the back panel body 10 is precisely positioned in the horizontal or vertical display position. This structure makes it easier for the protrusion 302 to slide into the slide rail 4011, improving the convenience and practicality of operation. At the same time, the interference fit ensures the stability of the back panel body 10 in the display position, preventing it from loosening or shifting during use.

[0051] In some embodiments, two symmetrically arranged socket portions 401 are provided back-to-back, and the connecting portion 402 is disposed on the side of the socket portion 401. By symmetrically arranging two socket portions 401, the two sides of the adapter 40 can be connected to two back panel fixing mechanisms 30 respectively, and then connected and fixed to an external fixing frame through the connecting portion 402, thereby realizing double-sided electronic price tag display. This not only improves the practicality of the back panel, but also enhances its adaptability in different scenarios. For example, when it is necessary to display two electronic price tags simultaneously, this structure can meet the requirements and improve the flexibility and functionality of the back panel. See reference Figure 11 Furthermore, it also includes a cover plate 50, which covers the sleeve portion of the adapter. The cover plate may be provided with a structural strip 501 adapted to the slide rail inside the sleeve portion. The structural strip is fixed by rotating and sliding into the slide rail. Alternatively, a sealing ring can be directly provided on the cover plate, filling the space between the sleeve portion and the cover plate for fixation. When only one sleeve portion is connected to the back plate body, the other unused sleeve portion can be sealed with the cover plate to achieve dust and water protection.

[0052] In some embodiments, the back panel fixing mechanism 30 is located at the center of the back of the back panel body 10. This improves the stability of the back panel body 10 after it is fixed to the external support frame. Placing the back panel fixing mechanism 30 in the center position ensures that the back panel body 10 remains balanced during the switching between horizontal and vertical display positions, reducing swaying or instability caused by a shift in the center of gravity. This not only improves the stability of the back panel but also enhances its adaptability to different display orientations, ensuring stable display of the electronic price tag during use.

[0053] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model.
