Description

Technical Field

[0001] This disclosure belongs to the field of electronic equipment technology, and specifically relates to an electronic price tag system, electronic price tag, and guide rail. Background Technology

[0002] Electronic shelf label (ESC) systems typically consist of an ESC body and mounting rails. The ESCs are detachably mounted to the rails on the edge of the shelf using a snap-fit ​​mechanism. The ESC body contains a display module and control circuitry. It generally has two power supply methods: battery power and power drawn from the conductive structure inside the ESC via conductive strips on the rails. Battery power requires regular battery replacements, resulting in high maintenance costs and environmental friendliness. Therefore, an increasing number of ESC systems are adopting conductive strip power.

[0003] Existing electronic shelf label systems typically use a rotation method to install electronic shelf labels onto guide rails. This involves first inserting one end of the electronic shelf label's locking mechanism into the guide rail's slot, then rotating the electronic shelf label body around that end as a fulcrum until the locking mechanism is in the corresponding locking position on the guide rail, thus completing the installation.

[0004] During rotation, the elastic conductive sheet of the electronic price tag rubs against the surface of the conductive strip on the guide rail, which can easily scratch the surface of the conductive strip and cause wear on the conductive sheet. After long-term use, the conductive sheet is prone to deformation and cannot spring back, resulting in unstable power supply. Summary of the Invention

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an electronic price tag system, electronic price tag, and guide rail.

[0006] Firstly, this disclosure provides an electronic price tag system, including: A guide rail having a mounting groove and two conductive strips disposed in the mounting groove; An electronic shelf label, comprising a display section, a connecting section extending rearward from the back of the display section, and a plug-in section extending upward from the end of the connecting section, wherein the display section is configured to house an electronic display screen and encapsulate a circuit board. The electronic price tag also includes two elastic conductive sheets, one end of each elastic conductive sheet is electrically connected to the circuit board and embedded in the connection part and the plug-in part, until the other end protrudes from the plug-in part; The electronic price tag also includes a flexible connector disposed on the plug-in portion and a hook disposed on the flexible connector; and... The electronic price tag is configured such that, under external force, the plug-in portion is gradually inserted into the mounting groove until, under the elastic force of the elastic connector, the hook engages in the corresponding slot of the guide rail, so that the two elastic conductive sheets abut against the two conductive strips respectively.

[0007] In one embodiment of this disclosure, after one end of the elastic connector is fixedly connected to the plug portion, it circumferentially surrounds a portion of the plug portion until the other end is fixedly connected to the plug portion.

[0008] In one embodiment of this disclosure, the elastic connector further has a pressing groove formed by bending towards the display portion.

The first arc segment and the second arc segment have opposite bending directions, and the central angle of the first arc segment is greater than the central angle of the second arc segment.

[0012] In one embodiment of this disclosure, the radial thickness of the second arc segment is less than the axial width of the second arc segment.

[0013] In one embodiment of this disclosure, the display unit includes a front cover and a rear cover, the plug-in part includes a plug-in housing and a plug-in cover, and the rear cover, the connecting part, and the plug-in housing are integrally formed; The second arc segment extends from the side of the plug housing near the rear cover.

[0014] In one embodiment of this disclosure, a first elastic buckle and a second elastic buckle are respectively provided on both sides of the plug cover, and a first snap-fit ​​hole and a second snap-fit ​​hole are correspondingly provided on the plug housing. The first elastic buckle and the second elastic buckle can slide into the first snap-fit ​​hole and the second snap-fit ​​hole along the plugging direction and engage under the action of external force, so that the plug cover is connected to the plug housing.

[0015] In one embodiment of this disclosure, two slots are provided on the sidewall of the mounting groove along the extension direction perpendicular to the guide rail, and the two conductive strips are respectively disposed in the two slots.

[0016] In one embodiment of this disclosure, the guide rail includes: The guide rail body has a mounting groove extending along the guide rail body, and two conductive sheets are disposed in the mounting groove; The mounting section, which extends rearward from the back of the guide rail body and bends downward, is configured to mount the guide rail body on a shelf. Two guide rail plugs are disposed at both ends of the guide rail body and are configured to block the mounting groove.

[0017] In one embodiment of this disclosure, the opening of the mounting slot faces downwards.

[0018] In a second aspect, this disclosure provides an electronic shelf label, which includes a display section, a connecting section extending rearward from the back of the display section, and a plug-in section extending upward from the end of the connecting section. The display section is configured to house an electronic display screen and encapsulate a circuit board. The electronic price tag also includes two elastic conductive sheets, one end of each elastic conductive sheet is electrically connected to the circuit board and embedded in the connection part and the plug-in part, until the other end protrudes from the plug-in part; The electronic price tag also includes a flexible connector disposed on the plug-in portion and a hook disposed on the flexible connector; and... The electronic price tag is configured such that, under external force, the plug-in portion is gradually inserted into the mounting groove of the guide rail until, under the elastic force of the elastic connector, the hook is engaged in the corresponding slot of the guide rail, so that the two elastic conductive sheets respectively abut against the two conductive strips of the guide rail.

[0019] Thirdly, this disclosure provides a guide rail for mounting electronic price tags, wherein the electronic price tag is the electronic price tag described in the previous embodiment, and the guide rail includes: The guide rail body has a mounting groove extending along the guide rail body, and two conductive pieces are disposed in the mounting groove; The mounting section, which extends rearward from the back of the guide rail body and bends downward, is configured to mount the guide rail body on a shelf. Two guide rail plugs are disposed at both ends of the guide rail body and are configured to block the mounting groove.

[0020] One of the beneficial effects of this disclosure is that the guide rail mounting groove of this disclosure is provided with two conductive strips for power supply.

Specifically, the electronic price tag has a display part, a connecting part extending rearward from the back of the display part, a plug-in part extending upward from the connecting part, and two elastic conductive sheets. The display part is used to mount the electronic display screen and encapsulate the circuit board. One end of the elastic conductive sheet is electrically connected to the circuit board and is embedded along the connecting part and the plug-in part until the other end protrudes from the plug-in part. Thus, under the action of external force, the plug-in part is gradually pushed into the mounting groove. At the same time, the elastic connecting part and the two elastic conductive sheets undergo elastic deformation until the hook on the elastic connecting part engages with the slot on the guide rail, so that the two elastic conductive sheets abut against the two conductive strips respectively, forming a current loop, and the electronic price tag receives power.

[0021] The electronic shelf label disclosed herein can be installed simply by inserting it into the mounting slot of the guide rail in a straight direction. This reduces the sliding friction distance between the elastic conductive sheet and the conductive strip, effectively preventing scratches on the conductive strip surface and wear on the conductive sheet, thus improving power supply stability. Furthermore, the plug-in installation method is simple and quick, significantly improving the installation efficiency of large-volume electronic shelf labels. Attached Figure Description

[0033] It should be noted that when describing the structure of the electronic shelf label system, the directional terms used in this article are based on the state of the electronic shelf label installed on the guide rail. See [link / reference needed]. Figure 4 The side of the electronic display screen on the electronic price tag is "front", the side of the back of the electronic display screen on the electronic price tag is "back", the top of the electronic price tag is "top", and the bottom of the electronic price tag is "bottom".

[0034] Electronic shelf label (ESC) systems typically consist of an ESC body and mounting rails. The ESCs are detachably mounted to the rails on the edge of the shelf using a snap-fit ​​mechanism. The ESC body contains a display module and control circuitry. It generally has two power supply methods: battery power and power drawn from the conductive structure inside the ESC via conductive strips on the rails. Battery power requires regular battery replacements, resulting in high maintenance costs and environmental friendliness. Therefore, an increasing number of ESC systems are adopting conductive strip power.

[0035] Existing electronic shelf label systems typically use a rotation method to install electronic shelf labels onto guide rails. This involves first inserting one end of the electronic shelf label's locking mechanism into the guide rail's slot, then rotating the electronic shelf label body around that end as a fulcrum until the locking mechanism is in the corresponding locking position on the guide rail, thus completing the installation.

[0036] During rotation, the elastic conductive sheet of the electronic price tag rubs against the surface of the conductive strip on the guide rail, which can easily scratch the surface of the conductive strip and cause wear on the conductive sheet. After long-term use, the conductive sheet is prone to deformation and cannot spring back, resulting in unstable power supply.

[0037] To this end, this disclosure provides an electronic shelf label system, which includes a guide rail and an electronic shelf label. The guide rail has a mounting groove and two conductive strips disposed in the mounting groove. The electronic shelf label includes a display section, a connecting section extending rearward from the back of the display section, and a plug-in section extending upward from the end of the connecting section. The display section is configured to house an electronic display screen and encapsulate a circuit board. The electronic shelf label also includes two elastic conductive sheets, one end of each elastic conductive sheet being electrically connected to the circuit board and embedded in the connecting section and the plug-in section until the other end protrudes from the plug-in section. The electronic shelf label also includes an elastic connector disposed on the plug-in section and a hook disposed on the elastic connector. Furthermore, the electronic shelf label is configured such that the plug-in section gradually inserts into the mounting groove under external force until the hook engages with the corresponding slot on the guide rail under the elastic force of the elastic connector, so that the two elastic conductive sheets abut against the two conductive strips respectively.

[0038] The guide rail mounting groove disclosed herein is provided with two conductive strips for power supply. An electronic price tag is inserted into this mounting groove to draw power. Specifically, the electronic price tag has a display section, a connecting section extending rearward from the back of the display section, an insertion section extending upward from the connecting section, and two elastic conductive sheets. The display section is used to mount an electronic display screen and encapsulate a circuit board. One end of each elastic conductive sheet is electrically connected to the circuit board and is embedded along the connecting section and the insertion section until the other end protrudes from the insertion section. Thus, under external force, the insertion section is gradually inserted into the mounting groove. Simultaneously, the elastic connecting member and the two elastic conductive sheets undergo elastic deformation until the hook on the elastic connecting member engages with the slot on the guide rail, causing the two elastic conductive sheets to abut against the two conductive strips respectively, forming a current loop, and the electronic price tag receives power.

[0039] The electronic shelf label disclosed herein can be installed simply by inserting it into the mounting slot of the guide rail in a straight direction. This reduces the sliding friction distance between the elastic conductive sheet and the conductive strip, effectively preventing scratches on the conductive strip surface and wear on the elastic conductive sheet, thus improving power supply stability. Furthermore, the plug-in installation method is simple and quick, significantly improving the installation efficiency of large-volume electronic shelf labels.

[0040] For ease of understanding, please refer to the following: Figures 1 to 12 The specific structure and working principle of the electronic price tag system provided in this disclosure will be described in detail with reference to the embodiments.

[0041] In one embodiment, this disclosure provides an electronic shelf label system, which includes a guide rail and an electronic shelf label. The guide rail has a mounting groove and two conductive strips 11 disposed in the mounting groove. The electronic shelf label includes a display portion 21, a connecting portion 22 extending rearward from the back of the display portion 21, and a plug-in portion 23 extending upward from the end of the connecting portion 22. The display portion 21 is configured to house an electronic display screen and encapsulate a circuit board. The electronic shelf label also includes two elastic conductive sheets 24, one end of each elastic conductive sheet 24 being electrically connected to the circuit board and embedded in the connecting portion 22 and the plug-in portion 23 until the other end protrudes from the plug-in portion 23. The electronic shelf label also includes an elastic connector 25 disposed on the plug-in portion 23 and a hook 26 disposed on the elastic connector 25. The electronic shelf label is configured such that the plug-in portion 23 is gradually inserted upward into the mounting groove under the push of an external force until the hook 26 is engaged in the corresponding slot 12 of the guide rail under the elastic force of the elastic connector 25, so that the two elastic conductive sheets 24 respectively abut against the two conductive strips 11.

[0042] Specifically, the guide rail is provided with a mounting groove, and two conductive strips 11 are embedded in the inner wall of the mounting groove. Specifically, the two conductive strips 11 can be spaced apart on the front side wall of the mounting groove along a direction perpendicular to the extension of the guide rail. The back of the guide rail is provided with a mounting part 13, which is arranged along the extension direction of the guide rail and forms a clamping groove together with the back of the guide rail to facilitate the installation of the guide rail on the shelf. In addition, in one embodiment, the two conductive strips 11 are spaced apart on the rear side wall of the mounting groove along a direction perpendicular to the extension of the guide rail, and two elastic conductive pieces 24 extend from the rear side of the insertion part 23 for abutting against the two conductive strips 11 respectively; or, the two conductive strips 11 are spaced apart on the upper end wall of the mounting groove along a direction perpendicular to the extension of the guide rail, and two elastic conductive pieces 24 extend from the upper end of the insertion part 23 for abutting against the two conductive strips 11 respectively. This disclosure does not impose any limitations.

[0043] The display section 21 has a display window, and the electronic display screen is fixed at the display window to display product information to consumers. The circuit board is located in the cavity formed by the front panel and the rear shell. One end of the elastic conductive sheet 24 is fixedly connected to the power supply terminal on the circuit board, and the other end is a free end that is embedded along the connecting part 22 and the plug-in part 23 to the other end, which extends out from the plug-in part 23. When the electronic price tag is installed on the guide rail, the free end elastically abuts against the conductive strip 11 in the guide rail mounting groove, introducing the electrical energy on the conductive strip 11 into the circuit board to power the electronic display screen and various functional modules.

[0044] Furthermore, the insertion portion 23 of the electronic price tag is connected to the display portion 21 via a connecting portion 22. The connecting portion 22 extends rearward relative to the display portion 21 to connect the insertion portion 23 and the display portion 21 as a whole and maintain their relative positions. One end of the elastic conductive sheet 24 is electrically connected to the circuit board inside the display portion 21, and the other end passes through the inside of the connecting portion 22 and extends to the outside of the insertion portion 23. When the insertion portion 23 is inserted into the mounting groove of the guide rail, the free end of the elastic conductive sheet 24 elastically abuts against the conductive strip 11 on the inner wall of the mounting groove.

[0045] The open ends of the guide rail mounting groove are respectively provided with a first guide slope and a second guide slope, combined with Figure 11 The first guide slope is set on the front side wall of the guide rail, and the second guide slope is set on the rear side wall of the guide rail. The two guide slopes gradually narrow inward from the opening of the mounting groove. When the plug part 23 of the electronic price tag is inserted into the mounting groove, the first guide slope contacts the elastic conductive sheet 24 and pushes the elastic conductive sheet 24 to deform along its surface. The second guide slope contacts the rear outer wall of the plug part 23 and guides the plug part 23 to slide into the mounting groove. Furthermore, the inclination angle of the first guide slope is greater than that of the second guide slope, thereby ensuring that the elastic conductive sheet 24 has a sufficient path to be squeezed, so that its elastic deformation is completed gradually, avoiding irreversible plastic deformation caused by the instantaneous large deformation of the elastic conductive sheet 24. The smaller inclination angle of the second guide slope ensures that it can guide while giving it sufficient strength, avoiding unstable engagement between the slot 12 and the hook 26. In this way, even if the initial position of the electronic price tag is slightly off when it is inserted, the two guide ramps can correct the insertion part 23 to the correct installation trajectory, avoiding the insertion part 23 from being misaligned and stuck or the elastic conductive sheet 24 from being misaligned and making poor contact with the conductive strip 11, thus reducing the precision requirements of the insertion operation. Users can complete the installation without precise alignment.

[0046] Furthermore, the plug-in part 23 is also provided with an elastic connector 25. The elastic connector 25 has a fixed end and a free end. The fixed end is integrally connected to the plug-in part 23, and the free end is located away from the fixed end along the plug-in direction and can undergo elastic deformation under the action of external force.

[0047] The elastic connector 25 is provided with a hook 26, which protrudes from the surface of the elastic connector 25 toward the inner wall of the mounting groove. When the insertion part 23 is inserted into the mounting groove, the hook 26 slides in together with the elastic connector 25. During the insertion process, the guide slope of the hook 26 is squeezed by the inner wall of the mounting groove, causing the elastic connector 25 to elastically contract inward. When the insertion part 23 is fully inserted, the hook 26 reaches the corresponding slot 12 on the inner wall of the mounting groove. The elastic connector 25 elastically resets, causing the hook 26 to engage in the slot 12. The lower side of the hook 26 abuts against the bottom surface of the slot 12 to limit the engagement and prevent the insertion part 23 from coming out in the opposite direction of insertion. During disassembly, the user presses the elastic connector 25 to retract the hook 26 inward and remove it from the slot 12, thus pulling the insertion part 23 out of the mounting groove.

[0048] When the electronic price tag is inserted into the mounting slot, the connecting part 22 abuts against the lower end face of the mounting slot, serving as a limit stop to determine the final insertion position of the price tag, preventing the price tag from being over-inserted, which could cause the elastic conductive sheet 24 to be over-compressed and deformed or the hook 26 to go beyond the position of the slot 12.

[0049] In addition, one of the two conductive strips 11 on the guide rail is a positive conductive strip and the other is a negative conductive strip. Correspondingly, the two elastic conductive pieces 24 on the electronic price tag are electrically connected to the positive power supply terminal and the negative power supply terminal on the circuit board, respectively. When the plug-in part 23 is inserted into the guide rail mounting slot, the positive elastic conductive piece 24 elastically abuts against the positive conductive strip, and the negative elastic conductive piece 24 elastically abuts against the negative conductive strip, forming two independent power supply paths, positive and negative.

[0050] See Figure 2 and Figure 3 In one embodiment, after one end of the elastic connector 25 of this disclosure is fixedly connected to the plug portion 23, it circumferentially surrounds the plug portion 23 until the other end is fixedly connected to the plug portion 23.

[0051] Specifically, the end of the elastic connector 25 is fixedly connected to the upper part of the plug-in portion 23, and the part of it surrounding the plug-in portion 23 forms two cantilever structures downward from the two fixed ends, and the lower ends of the two cantilever are connected to surround each other, so that the elastic connector 25 surrounds the middle and lower part of the plug-in portion 23 in the circumferential direction, and the hook 26 is provided on the rear side of the elastic connector 25 and protrudes backward.

[0052] When the plug part 23 is inserted into the guide rail mounting groove, the upper part of the elastic connector 25 slides in together with the plug part 23. The hook 26 slides into contact with the second guide slope and is squeezed, causing the elastic connector 25 to deform forward elastically. When the plug part 23 is inserted into the position, the hook 26 reaches the position of the slot 12 on the inner wall of the mounting groove. The elastic connector 25 elastically resets, causing the hook 26 to spring into the slot 12 and lock.

[0053] To disassemble, the user presses the lower end of the elastic connector 25 from below the insertion part 23, causing it to deform forward and pull the hook 26 out of the slot 12, allowing it to be pulled out. Alternatively, the user can unlock it by pressing horizontally below the price tag; no tools are required.

[0054] See Figure 2 , Figure 3 and Figure 6 In one embodiment, the elastic connector 25 of this disclosure also has a pressing groove 251 formed by bending towards the display portion 21. The pressing groove 251 is configured to apply external force when removing the electronic price tag from the guide rail, so that the elastic connector 25 deforms until the hook 26 disengages from the slot 12.

[0055] In detail, the portion of the elastic connector 25 surrounding the insertion portion 23 circumferentially has a recessed pressing groove 251 formed by bending towards the display portion 21. When the insertion portion 23 is inserted into the guide rail mounting groove, the hooks 26 slide in with the elastic connector 25 and retract inward under the pressure of the second guide slope. After insertion, the elastic connector 25 resets, causing the hooks 26 to engage with the locking groove 12 on the inner wall of the mounting groove. During disassembly, the user squeezes the display portion 21 and the pressing groove 251 with one hand. The pressing groove 251 moves forward under force, causing the two hooks 26 to disengage from the locking groove 12, and the insertion portion 23 can be pulled out of the mounting groove, realizing a quick disassembly operation by pressing and unlocking from the front with one hand.

[0056] See Figure 2 and Figure 3 In one embodiment, the elastic connector 25 of this disclosure is a U-shaped elastic connector, with at least two hooks 26 respectively disposed on two cantilever arms of the elastic connector 25, and a pressing groove 251 disposed between at least two cantilever arms.

[0057] Thus, the two ends of the U-shaped elastic connector 25 extend from the top of the insertion part 23 to the left and right sides respectively, then bend downwards and converge towards the middle to encircle the outside of the insertion part 23. A recessed pressing groove 251 is provided at the bottom between the two cantilever arms. When the pressing groove 251 is subjected to force, the two cantilever arms deform synchronously and symmetrically, and the force is even and not biased, avoiding the locking of the hook 26 on one side or inconsistent disengagement. After the external force is removed, the elastic connector 25 can quickly spring back, and the hook 26 can reliably re-engage into the groove 12.

[0058] See Figure 3 In one embodiment, the hook 26 is located in the middle of the cantilever and protrudes outward from the rear surface of the elastic connector 25. The hook 26 being located in the middle, rather than at the free end, amplifies the lever arm between the pressing groove 251 and the hook 26, allowing the user to disengage the hook 26 with less pressing force. Simultaneously, the central location of the hook 26 brings the locking point closer to the insertion part 23, resulting in a more secure fit after insertion and reducing the likelihood of the hook 26 wobbling or failing to lock properly.

[0059] See Figure 2 , Figure 4 and Figure 5 In one embodiment, along the front-back direction of the electronic price tag, the rear side of the upper end of the elastic connector 25 is not higher than the rear side of the plug-in portion 23, and the rear side of the lower end of the elastic connector 25 is not lower than the rear side of the plug-in portion 23.

[0060] In other words, the elastic connector 25 disclosed herein has two cantilever structures, and the two fixed ends of the elastic connector 25 are arranged close to the front side of the insertion part 23, leaving elastic deformation space at the rear. The rear side of the lower end of the elastic connector 25 is not lower than the rear side of the insertion part 23, so that it extends inclinedly from the fixed end to the rear and downward. In this way, the elastic connector 25 has a sufficient deformation path.

[0061] See Figure 7 , Figure 8 and Figure 9 In one embodiment, the elastic conductive sheet 24 of this disclosure includes a first straight segment 241, a first arc segment 242, a second straight segment 243, a third straight segment 244, a second arc segment 245, and a fourth straight segment 246, which are sequentially fixedly connected by a smooth curve; the free end of the first straight segment 241 is fixedly connected to a circuit board; the first arc segment 242 is bent towards the display unit 21 from the other end of the first straight segment 241; the second straight segment 243 is inclined upward relative to the first arc segment 242; the third straight segment 244 is inclined towards the display unit 21 relative to the second straight segment 243; the second arc segment 245 is bent backward relative to the display unit 21 from the other end of the third straight segment 244; the fourth straight segment 246 extends along the tangent direction of the free end of the second arc segment 245; the bending directions of the first arc segment 242 and the second arc segment 245 are opposite, and the central angle of the first arc segment 242 is greater than the central angle of the second arc segment 245.

[0062] In detail, the first straight segment 241 is fixedly connected to the circuit board inside the display unit 21, used to position and install the elastic conductive sheet 24 and electrically connect it to the power supply terminal of the circuit board. The first arc segment 242 extends backward from the first straight segment 241 and bends forward to form a curved structure, thereby generating elastic deformation under external force and returning to its original position after the external force is removed. The curved structure gives the elastic conductive sheet 24 a longer effective elastic deformation length in the same installation space, reduces the stress corresponding to the deformation, and improves the reliability of the electronic label after repeated insertion and removal.

[0063] The second straight segment 243 is inclined upward relative to the first arc segment 242 and extends to the spring opening on the front side of the insertion part 23, thereby extending the distance between the second arc segment 245 and the first arc segment 242. The overall flexibility of the elastic conductive sheet 24 is increased, the pressure under the same amount of pressure deformation is more gentle and stable, it is not easy to undergo plastic deformation due to excessive local deformation, and it can adapt to a larger deformation stroke without exceeding the elastic limit. The contact pressure between the second arc segment 245 and the conductive strip 11 changes more gradually throughout the insertion process, and the final electrical connection after positioning is more stable and reliable.

[0064] The third straight segment 244, the second arc segment 245, and the fourth straight segment 246 form a V-shaped structure. The second arc segment 245 forms an arc-shaped contact surface. When the elastic conductive sheet 24 comes into contact with the conductive strip 11, the fourth straight segment 246 first guides the elastic conductive sheet 24 and the conductive strip 11 to slide into contact. The second arc segment 245 makes the contact process gradually transition from point contact to surface contact, avoiding surface scratches caused by the flat end section directly impacting the conductive strip 11.

[0065] The bending directions of the first arc segment 242 and the second arc segment 245 are opposite. The first arc segment 242 of the elastic conductive sheet 24 can undergo elastic deformation, and the second arc segment 245 is convenient for alignment with the conductive strip 11 on the inner wall of the guide rail. Moreover, the central angle of the first arc segment 242 is larger than that of the second arc segment 245. The first arc segment 242 with a larger central angle is the main elastic deformation area, providing most of the elastic recovery force when compressed. The second arc segment 245 with a smaller central angle is mainly used for contact with the conductive sheet. In this way, the elastic deformation is concentrated in one section, ensuring the stability of the electrical connection.

[0066] See Figure 9 In one embodiment, the radial thickness of the second arc segment 245 of this disclosure is less than the axial width of the second arc segment 245.

[0067] In this way, the second arc segment 245 forms a flat, wide, and thin structure, ensuring sufficient contact area with the conductive strip 11. When the electronic price tag has slight left and right wobbling in the mounting slot, the second arc segment 245 can still maintain effective contact with the conductive strip 11, and will not cause power failure due to slight displacement. Furthermore, the electronic price tag does not need to be inserted into the guide rail and rotated for connection; it only needs to be inserted in a straight line. The second arc segment 245 will not generate excessive frictional wear with the conductive sheet.

[0068] See Figure 3 , Figure 5 and Figure 7In one embodiment, the display part 21 of this disclosure includes a front cover 211 and a rear cover 212, and the plug-in part 23 includes a plug-in housing 231 and a plug-in cover 232. The rear cover 212, the connecting part 22, and the plug-in housing 231 are integrally formed; the second arc segment 245 extends from the side of the plug-in housing 231 near the rear cover 212.

[0069] Specifically, the front cover 211 has a display window for mounting an electronic display screen, and the rear cover 212 is fastened to the front cover 211 to form a cavity for accommodating a circuit board.

[0070] The plug-in part 23 includes a plug-in housing 231 and a plug-in cover 232. The plug-in housing 231 is a hollow housing structure with an internal space for the installation and movement of the elastic conductive sheet 24. The plug-in cover 232 is placed on the rear side of the plug-in housing 231 to encapsulate the internal structure.

[0071] The elastic conductive sheet 24 passes through the plug-in housing 231 and is electrically connected to the circuit board inside the display unit. Afterward, sealant is used to fill the gap through which the elastic conductive sheet 24 passes to prevent liquid from entering the display unit.

[0072] The back cover 212, connecting part 22, and plug-in housing 231 are integrally molded, forming a continuous housing structure through injection molding. This eliminates the seams between the back cover 212 and connecting part 22, as well as between the connecting part 22 and plug-in housing 231, improving the structural strength and sealing of the housing and preventing dust and liquid from seeping into the housing through the seams and damaging the circuit board and elastic conductive sheet 24. The integral molding also reduces assembly steps and the number of parts, lowering production costs, while avoiding housing deformation and abnormal noise caused by loosening at the joints during repeated plugging and unplugging of a separate, spliced ​​structure.

[0073] The front cover 211 and the plug cover 232 are installed as independent covers from the front and rear respectively, which facilitates the assembly, maintenance and replacement of the circuit board and the elastic conductive sheet 24. During assembly, the circuit board and the elastic conductive sheet 24 are first installed in the integrally formed rear shell, and then the front cover 211 and the plug cover 232 are fastened to complete the assembly.

[0074] See Figure 5 , Figure 6 and Figure 12 In one embodiment, the plug cover 232 of this disclosure is provided with a first elastic buckle 2321 and a second elastic buckle 2322 on both sides, and the plug housing 231 is provided with a first snap hole 2311 and a second snap hole 2312. The first elastic buckle 2321 and the second elastic buckle 2322 can slide into the first snap hole 2311 and the second snap hole 2312 along the plugging direction and engage under the action of external force, so that the plug cover 232 is connected to the plug housing 231.

[0075] Specifically, the first elastic buckle 2321 and the second elastic buckle 2322 can slide into the first snap-fit ​​hole 2311 and the second snap-fit ​​hole 2312 respectively along the closing direction under the action of external force and engage, so that the plug cover 232 is connected to the plug housing 231. The first elastic buckle 2321 on the upper side of the plug cover 232 is shorter than the second elastic buckle 2322 on the lower side. Correspondingly, the first snap-fit ​​hole 2311 is located in the middle of the top end face of the plug part 23, while since the plug housing 231 and the connecting part 22 are integrally formed, the second snap-fit ​​hole 2312 is located in the middle of the bottom end face of the plug housing 231 and the connecting part 22, thereby increasing the stability of the engagement.

[0076] Two types of elastic clips are fixed to the front side of the plug-in cover 232. Their free ends have a wedge shape with a cross-section that gradually decreases towards the outside of the plug-in housing 231. This allows the elastic clips to be guided along the edge of the locking hole and slide in during insertion. Once in place, they reset under their own elasticity and lock into the locking hole to complete the fastening and locking process. The elastic clips and the plug-in cover 232 are integrally injection molded, making them resistant to plastic deformation and failure after repeated assembly and disassembly.

[0077] In addition, the first snap-fit ​​hole 2311 and the second snap-fit ​​hole 2312 can also be used to drain liquid that seeps into the electronic price tag during use, so as to prevent liquid from accumulating in the plug housing 231 and causing corrosion of the elastic conductive sheet 24.

[0078] See Figure 10 and Figure 11 In one embodiment, two slots are provided on the side wall of the mounting groove of this disclosure along the extension direction of the vertical guide rail, and two conductive strips 11 are respectively disposed in the two slots.

[0079] Specifically, along the extension direction perpendicular to the guide rail, two slots are provided on the front side wall of the mounting groove, and two conductive strips 11 are respectively placed in the two slots and distributed at intervals in the vertical direction. Correspondingly, two elastic conductive pieces 24 on the electronic price tag also correspond to the two conductive strips 11 respectively. When inserted, the two elastic conductive pieces 24 simultaneously abut against the two conductive strips 11 on the front side wall from the front.

[0080] Furthermore, the slot 12 extends along the guide rail and is located on the rear wall of the mounting groove. The hook 26 is located on the rear side of the elastic connector 25. When inserted into place, the hook 26 engages with the slot 12 from the rear and locks in place. The conductive contact and locking mechanism are respectively arranged on the front and rear sides of the mounting groove, so that when the conductive sheet on the front side contacts the conductive strip 11, it does not bear the axial tension of the hook 26 locking. When the hook 26 on the rear side locks in place, it does not interfere with the conductive contact state on the front side. The two functional areas are separated front and rear and do not interfere with each other. Changes in force on one side will not cause poor contact or loosening of the lock on the other side. At the same time, the separation of the conductive strip 11 and the slot 12 in the front and rear direction provides support for both the front and rear walls of the insertion part 23. After insertion, both the front and rear sides are constrained by force, and the electronic price tag does not wobble back and forth in the mounting groove.

[0081] See Figure 10 and Figure 11 In one embodiment, the opening of the mounting slot of this disclosure faces downward.

[0082] In this way, the electronic shelf label is inserted into the mounting slot in a straight line from bottom to top, preventing the connector 23 of the electronic shelf label from rotating inside the mounting slot and rubbing against the conductive strip 11 and the elastic conductive sheet 24. This also ensures smooth operation and prevents misalignment. For maintenance or disassembly, it can be removed directly from below. During daily use, dust and debris fall downwards due to gravity and will not enter the mounting slot from the bottom opening and accumulate on the conductive strip, thus helping to maintain long-term reliable conductive contact.

[0083] Meanwhile, once liquid seeps in, the accumulated liquid will collect along the inner wall of the mounting groove under the action of gravity and drip directly downwards, without accumulating in the groove or on the electronic price tag. This avoids the long-term stagnation of liquid and its corrosion of the conductive strip 11, allowing the electronic price tag system of this disclosure to still work stably in a humid environment.

[0084] Alternatively, in one embodiment, the opening of the mounting slot of this disclosure faces upward.

[0085] The opening of the mounting slot is set upward. The electronic price tag of this disclosure is inserted into the mounting slot from above and downward. Gravity naturally assists the insertion part 23 to align and enter the slot. The electronic price tag is stably placed at the bottom of the slot under the action of gravity. The elastic conductive sheet 24 and the conductive strip 11 maintain continuous and tight contact and will not loosen or have poor contact due to its own weight.

[0086] See Figure 11 In one embodiment, the guide rail of this disclosure includes a guide rail body 10, a mounting portion 13, and two guide rail plugs 14. The guide rail body 10 is provided with a mounting groove extending along the guide rail body 10 and opening downward, and two conductive sheets are disposed in the mounting groove. The mounting portion 13 is formed by extending rearward from the back of the guide rail body 10 and bending downward, and is configured to mount the guide rail body 10 on a shelf. The two guide rail plugs 14 are disposed at both ends of the guide rail body 10 and are configured to block the mounting groove.

[0087] Specifically, the guide rail body 10 has a mounting groove, and two conductive strips 11 are embedded in the inner wall of the mounting groove. The mounting part 13 is located on the back of the guide rail body 10, along the extension direction of the guide rail, and together with the back of the guide rail body 10, forms a clamping groove. The free end of the mounting part 13 is a wedge shape with a cross-sectional area larger than the free end and a gradually decreasing cross-sectional area downward, so that the guide rail body 10 can be inserted into and fixed on the shelf without the need for screws or other fasteners, making disassembly and assembly convenient and without damaging the shelf structure.

[0088] Two guide rail plugs 14 are respectively set at both ends of the guide rail body 10 to seal the end opening of the mounting groove, prevent dust and foreign objects from entering the mounting groove from the end and contaminating the contact surface of the conductive strip 11, ensure reliable electrical contact between the conductive strip 11 and the elastic conductive sheet 24, and at the same time, the plugs also play an axial limiting role for the components in the mounting groove.

[0089] In addition, the guide rail also has a power supply adapter that is electrically connected to the conductive strip 11 via a connecting wire, for transmitting electrical signals from an external power source to the conductive strip 11 to power the electronic price tags inserted on the guide rail.

[0090] Secondly, see Figure 2 This disclosure provides an electronic shelf label, which includes a display portion 21, a connecting portion 22 extending rearward from the back of the display portion 21, and a plug-in portion 23 extending upward from the end of the connecting portion 22. The display portion 21 is configured to house an electronic display screen and encapsulate a circuit board. The electronic shelf label also includes two elastic conductive sheets 24, one end of each elastic conductive sheet 24 being electrically connected to the circuit board and embedded in the connecting portion 22 and the plug-in portion 23, until the other end protrudes from the plug-in portion 23. The electronic shelf label also includes an elastic connector 25 disposed on the plug-in portion 23 and a hook 26 disposed on the elastic connector 25. Furthermore, the electronic shelf label is configured such that the plug-in portion 23 is gradually inserted into the mounting groove of the guide rail under the push of an external force, until the hook 26 is engaged in the corresponding slot 12 of the guide rail under the elastic force of the elastic connector 25, so that the two elastic conductive sheets 24 respectively abut against the two conductive strips 11.

[0091] The disclosed electronic price tag is powered by insertion. Specifically, the electronic price tag has a display part 21, a connecting part 22 extending rearward from the back of the display part 21, an insertion part 23 extending upward from the connecting part 22, and two elastic conductive sheets 24. The display part 21 is used to mount the electronic display screen and encapsulate the circuit board. One end of the elastic conductive sheet 24 is electrically connected to the circuit board and is embedded along the connecting part 22 and the insertion part 23 until the other end protrudes from the insertion part 23. Thus, under the action of external force, the insertion part 23 is pushed upward into the mounting groove. At the same time, the elastic connector 25 and the two elastic conductive sheets 24 undergo elastic deformation until the hook 26 on the elastic connector 25 engages in the slot 12 on the guide rail, so that the two elastic conductive sheets 24 respectively abut against the two conductive strips 11, forming a current loop, and the electronic price tag is powered.

[0092] In other words, the electronic price tag disclosed herein can be installed simply by inserting it into the mounting slot of the guide rail in a straight line. This reduces the sliding friction distance between the elastic conductive sheet 24 and the conductive strip 11, effectively preventing scratches on the surface of the conductive strip 11 and wear on the conductive sheet, thus improving power supply stability.

[0093] Thirdly, see Figure 1 and Figure 11 This disclosure provides a guide rail for installing electronic shelf labels, which are the same as those described in the previous embodiment. The guide rail includes a guide rail body 10, a mounting part 13, and two guide rail plugs 14. The guide rail body 10 has a mounting groove extending along the guide rail body 10, and two conductive sheets are disposed in the mounting groove. The mounting part 13 is formed by extending rearward from the back of the guide rail body 10 and bending downward, and is configured to install the guide rail body 10 on a shelf. The two guide rail plugs 14 are disposed at both ends of the guide rail body 10 and are configured to block the mounting groove.

[0094] Thus, this disclosure adopts a plug-in installation method, which is simple and quick to operate, significantly improving the installation efficiency of large-volume electronic shelf labels. Furthermore, the guide rail uses a clamp-on installation method, which can be fixed to the shelf without screws or tools, allowing for quick assembly and disassembly without damaging the shelf. Its sealed ends prevent dust and foreign objects from entering, maintaining internal cleanliness.

[0095] Furthermore, the guide rail body 10 of this disclosure is manufactured using an extrusion plastic process. Heated and molten plastic is continuously extruded through a die and cooled to solidify, resulting in a long strip with a consistent cross-sectional shape, which can then be cut to the required length for use. This process makes the guide rail body 10 suitable for mass continuous production, ensuring consistent cross-sectional precision and low manufacturing costs. Moreover, the plastic material itself is insulating, and the conductive strip 11, once embedded in the inner wall of the mounting groove, requires no additional insulation, preventing short circuits. Additionally, the plastic is lightweight, so it does not add extra load when installed on shelves.

[0096] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein. The scope of this disclosure is defined by the appended claims.
