Description

Technical Field

[0001] This utility model relates to the field of price tag technology, specifically to electronic price tags. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] Electronic shelf labels (ESLs), also known as electronic shelf labels, are electronic display devices with information transmission and reception capabilities. They are mainly used in supermarkets, convenience stores, pharmacies, etc., and can replace traditional paper price tags. The working principle of electronic shelf labels is: they receive product information from a data transmission device via wired or wireless communication and display the received product information on the electronic shelf label.

[0004] After prolonged use, electronic price tags require regular replacement and maintenance of their internal components, specifically the e-ink display, to ensure long-term usability. However, current e-ink displays are typically secured with bolts, a method that is time-consuming, labor-intensive, and inefficient when performing batch replacements and maintenance. Utility Model Content

[0005] The main purpose of this utility model is to provide electronic price tags.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: an electronic price tag includes a housing, the housing having a receiving cavity, the receiving cavity housing an electronic ink screen and a clamping assembly.

[0007] A mating rod is rotatably inserted into the outer wall of the outer casing on the side away from the receiving cavity, and mounting seats are spaced apart on the side of the outer casing away from the receiving cavity.

[0008] The mounting base has a mating hole on the side facing the outer shell for inserting the mating rod, and the side of the mounting base away from the outer shell is installed at the corresponding position on the shelf;

[0009] Specifically, by twisting the docking rod, the clamping assembly is driven to lock the relative position of the electronic ink screen in the receiving cavity.

[0010] Furthermore, the clamping assembly includes a turntable disposed in the receiving cavity, and one end of the docking rod away from the mounting base extends into the receiving cavity and is inserted and fixed at the center of the turntable. The turntable surface has four first limiting grooves extending in a circular array, each curving in a concentric direction.

[0011] The turntable has a cavity on the side away from the mounting base with a partition plate fixed at intervals parallel to it. The partition plate has four radially extending second limiting grooves arranged in a circular array on its surface.

[0012] A limiting rod parallel to the axis of the turntable is slidably inserted into each of the first limiting grooves, and one end of the limiting rod is slidably inserted into the corresponding second limiting groove;

[0013] Each of the limiting rods has a clamping plate elastically provided on the outer wall near the e-ink screen. A first positioning space is formed between two clamping plates located in the same vertical direction for positioning the top and bottom edges of the e-ink screen; a second positioning space is formed between two clamping plates located in the same horizontal direction for positioning the two sides of the e-ink screen.

[0014] Furthermore, a telescopic rod is provided between the limiting rod and the corresponding clamping plate, and a spring is sleeved on the outside of the telescopic rod.

[0015] Furthermore, the partition is secured within the receiving cavity by bolts.

[0016] Furthermore, a cover plate is provided on the side of the housing away from the mounting base, and the cover plate has a viewing window corresponding to the position of the e-ink screen.

[0017] Furthermore, the mounting base has a slot with a connecting hole on the side facing the outer shell, and the outer wall of the connecting rod has a locking block that mates with the slot.

[0018] When the docking rod is turned to lock the relative position of the electronic ink screen in the receiving cavity, the locking block and the locking slot are aligned in the same straight line direction.

[0019] The beneficial effects of this utility model are reflected in:

[0020] This utility model of electronic price tag breaks with the original approach by adding a connecting rod and clamping components to the original shell. The electronic ink screen can be easily and efficiently disassembled and assembled by simply twisting the connecting rod, which greatly improves the efficiency of batch maintenance operations.

[0021] The electronic price tag of this utility model, through the locking block set on the docking rod and the locking groove on the mounting base, not only fixes the electronic ink screen in the shell by turning the docking rod, but also prepares for the locking between the locking block and the locking groove, that is, provides the necessary conditions for the installation of the shell on the mounting base, and specifies an installation sequence to prevent incorrect installation, thereby further improving work efficiency.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0034] Please combine Figures 1 to 8 ,

[0035] The electronic price tag includes a housing 1, which is rectangular in shape. The housing 1 has a receiving cavity 14, which houses an electronic ink screen 3 and a clamping assembly.

[0036] A mating rod 5 is rotatably inserted into the outer wall of the outer casing 1 on the side away from the receiving cavity 14, and mounting seats 6 are spaced apart on the side of the outer casing 1 away from the receiving cavity 14.

[0037] The mounting base 6 has a mating hole 61 on the side facing the outer casing 1 for inserting the mating rod 5. The side of the mounting base 6 away from the outer casing 1 is installed in the corresponding position on the shelf. The mounting base 6 can be fixed on the shelf by bolts or clips.

[0038] In practice, during assembly, the e-ink screen 3 is placed into the receiving cavity 14, and the docking rod 5 is turned to drive the clamping assembly to lock the relative position of the e-ink screen 3 in the receiving cavity 14. Then, the docking rod 5 is inserted into the docking hole 61 of the mounting base 6 to finally complete the installation of the electronic price tag on the shelf.

[0039] The electronic price tag of this application houses the e-ink screen 3 in the housing 1, which can provide good protection for the e-ink screen 3. In addition, the positioning or removal of the e-ink screen 3 in the housing 1 can be achieved conveniently and efficiently by simply turning the connecting rod 5 and using the clamping component, which is stable and reliable.

[0040] It should be noted that the housing cavity 14 of the outer casing 1 of this application also houses a circuit board (not shown) and a battery (not shown). The battery is connected to the circuit board via wires, and the circuit board is connected to the e-ink screen 3 via wires, responsible for supplying power to the e-ink screen 3 and transmitting display signals. The circuit board serves as the power distribution and signal control center, connecting the battery and the e-ink screen. The button battery provides a stable power supply to the circuit board and the e-ink screen through parallel or series connection, supporting long-term use. As the e-ink screen is a low-power display unit, it relies on the circuit board for power supply and signal control. Since the circuit board and e-ink screen are existing technologies, this application will not elaborate further on them.

[0041] In one embodiment, the clamping assembly includes a turntable 8 disposed in a receiving cavity 14. The end of the docking rod 5 away from the mounting base 6 extends into the receiving cavity 14 and is inserted and fixed at the center of the turntable 8. Four first limiting grooves 9 extending in a concentric bend are formed on the surface of the turntable 8 in a circular array. A partition plate 10 parallel to the turntable 8 is fixed at intervals in the receiving cavity 14 on the side of the turntable 8 away from the mounting base 6. Four second limiting grooves 11 extending radially are formed on the surface of the partition plate 10 in a circular array.

[0042] Each first limiting groove 9 is slidably inserted with a limiting rod 12 parallel to the axis of the turntable 8, and one end of the limiting rod 12 is slidably inserted in the corresponding second limiting groove 11;

[0043] Each limiting rod 12 has a clamp 7 elastically provided on the outer wall near the electronic ink screen 3.

[0044] A first positioning space is formed between two clamping plates 7 located in the same vertical direction for positioning the top and bottom edges of the e-ink screen 3; a second positioning space is formed between two clamping plates 7 located in the same horizontal direction for positioning the two sides of the e-ink screen 3.

[0045] In practice, during assembly, the e-ink screen 3 is placed on the partition 10, and then the connecting rod 5 is turned. The connecting rod 5 drives the turntable 8 to rotate synchronously, so that the groove walls of the first limiting grooves 9 that extend inward continuously rub and squeeze the limiting rods 12. Under the joint limiting action of the radially extending second limiting grooves 11, the limiting rods 12 move inward, so that each limiting rod 12 drives the corresponding clamping plate 7 to approach the outer wall of the corresponding side of the e-ink screen 3 through its respective telescopic rod, thereby completing the clamping and fixing of the e-ink screen 3 in the receiving cavity 14 of the outer shell 1.

[0046] The advantage of this design is that the four sides of the e-ink screen 3 can be clamped and fixed simultaneously by simply rotating the limiting rod 12, which is stable and reliable.

[0047] Preferably, a telescopic rod 13 is provided between the limiting rod 12 and the corresponding clamping plate 7, and a spring (not shown) is sleeved on the outside of the telescopic rod 13. The telescopic rod 13 and the spring can buffer the clamping force of the clamping plate 7 on the e-ink screen 3, so as to avoid damage to the e-ink screen 3.

[0048] Preferably, the partition 10 is fixed in the receiving cavity 14 by bolts, which facilitates the disassembly or installation of the partition 10 in the receiving cavity 14.

[0049] In one embodiment, a cover plate 2 is provided on the side of the housing 1 away from the mounting base 6, and the cover plate 2 has a viewing window 4 corresponding to the position of the electronic ink screen 3.

[0050] The purpose of this design is to provide physical isolation for the e-ink screen 3, preventing moisture or pollutants in the external environment from directly contacting the e-ink screen 3 and avoiding short circuits or mechanical damage.

[0051] In one embodiment, the mounting base 6 has a slot 16 with a connecting hole 61 on the side facing the outer shell 1, and a locking block 15 that mates with the slot 16 is provided on the outer wall of the connecting rod 5.

[0052] When the docking rod 5 is turned to lock the relative position of the electronic ink screen 3 in the receiving cavity 14, the locking block 15 and the slot 16 are aligned in the same straight line direction.

[0053] In practice, when the docking rod 5 is not turned, the locking block 15 and the locking slot 16 are in a misaligned position. At this time, the docking rod 5 cannot be inserted into the docking hole 61. Only when the docking rod 5 is turned (the electronic ink screen 3 is in a locked position) can the positions of the locking block 15 and the locking slot 16 correspond to each other. Only then can the docking rod 5 be inserted into the docking hole 61. With the use of the locking block 15 and the locking slot 16, the outer shell 1 is stably fixed on the mounting base 6.

[0054] The advantage of this design is that turning the connecting rod 5 not only fixes the e-ink screen 3 in the housing 1, but also prepares for the snap-fit ​​between the clip 15 and the slot 16, thus providing the necessary conditions for the installation of the housing 1 on the mounting base 6, and also specifies an installation sequence to prevent incorrect installation and improve the efficiency of disassembly and assembly.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0056] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0057] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions of "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.
