Description

Technical Field

[0001] The utility model relates to the technical field of electronic price tags, in particular to an electronic price tag. Background Art

[0002] An electronic price tag (digital signage) is an electronic display device with information receiving and transmitting functions, mainly used as an electronic label for displaying price information in supermarkets, convenience stores, pharmacies, etc. It is set on the shelf or other positions close to the commodity and can replace the traditional paper price tag. During use, the setting of the electronic price tag enables the staff to get rid of the situation of manually replacing the price tag and can achieve price consistency between the cash register and the shelf.

[0003] The main disadvantage of the existing electronic price tag in terms of structure is that the electrical connection scheme of the detachable battery generally adopts the way of directly contacting the metal elastic sheet with the soft package battery tab. This power supply connection method for the detachable soft package battery is not applicable to the electrical connection of multiple batteries. In the demand scenario of multiple batteries, the existing electrical connection method often requires a larger structural space and extremely high-precision processing and assembly tolerances, and it is basically impossible to achieve high-quality mass production.

[0004] Therefore, based on the experience and practice of being engaged in the relevant industry for many years, the inventor of the present utility model proposes an electronic price tag to solve at least one of the above technical problems. Summary of the Utility Model

[0052] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the detailed implementation manner of the present utility model will now be described with reference to the accompanying drawings.

[0053] As Figures 1 to 10 shown, the present utility model provides an electronic price tag. Multiple batteries 2 and a power supply adapter 1 are arranged inside the electronic price tag. The power supply adapter 1 is connected to the circuit board 3 of the electronic price tag. The tabs of the multiple batteries 2 are respectively connected to the power supply adapter 1, so as to connect the multiple batteries 2 in parallel to the circuit board 3 through the power supply adapter 1.

[0054] In the present utility model, a power supply adapter 1 is additionally provided inside the electronic price tag. The power supply adapter 1 serves as a "bridge" connecting multiple batteries 2 and the circuit board 3 of the electronic price tag. One side of the power supply adapter 1 is connected to the circuit board 3, and the tabs of multiple batteries 2 are respectively connected to the other opposite side of the power supply adapter 1 in a parallel connection manner. Through the power supply adapter 1, multiple batteries 2 are connected in parallel to the circuit board 3. Thus, through the arrangement of the power supply adapter 1, the connection of multiple batteries 2 is realized simultaneously, which not only meets the power supply requirement of the electronic price tag, but also the arrangement of the power supply adapter 1 can reserve a large area of PAD regions (as contact points for chip pin connection) for the connection of the spring pieces on the circuit board 3. Compared with the traditional connection method where the tab of each battery 2 is individually connected to the spring piece on the circuit board 3, the connection method of the power supply adapter 1 does not require precise alignment of the spring pieces anymore, and the power supply connection of the battery can be realized within the relatively small height space inside the electronic price tag.

[0055] In an alternative embodiment of the present utility model, as Figures 2 to 4 shown, the power supply adapter 1 is in a long strip plate-like structure. In the length direction of the power supply adapter 1, the power supply adapter 1 respectively has opposite first connection surfaces 101 and second connection surfaces 102 (i.e., the opposite side surfaces of the two long sides of the long strip plate); the batteries 2 and the circuit board 3 are respectively located on both sides of the power supply adapter 1. The tabs of multiple batteries 2 are respectively connected to the first connection surface 101, and the spring pieces provided on the circuit board 3 are connected (in contact) with the second connection surface 102. In the present utility model, the large area regions left by the first connection surface 101 and the second connection surface 102 on the power supply adapter 1 respectively serve as connection structures for delivering current between the tabs of multiple batteries 2 and the spring pieces provided on the circuit board 3. As long as it is ensured that the tabs of the batteries 2 and the spring pieces provided on the circuit board 3 are respectively connected to the power supply adapter 1, therefore, there is no need to require precise alignment connection between the tabs of the batteries 2 and the spring pieces on the circuit board 3 anymore, and the stable power supply of the batteries 2 to the electronic price tag can be ensured, thereby ensuring the stable working state of the electronic price tag.

[0056] In an alternative embodiment of the present utility model, as Figure 3 shown, multiple pads 103 corresponding to the positions of the tabs of multiple batteries 2 are provided on the first connection surface 101 of the power supply adapter 1. The area of the pads 103 is larger than the area of the corresponding tabs of the batteries 2. The multiple pads 103 are respectively used for welding with the corresponding tabs of the batteries 2. Through the arrangement of the pads 103 on the power supply adapter 1, it is ensured that the tabs of the batteries 2 can be accurately and stably welded to the power supply adapter 1, and even without precise alignment, a stable connection state between the tabs of the batteries 2 and the circuit board 3 can be ensured.

[0057] In an alternative embodiment of the present utility model, as Figure 4As shown, on the second connection surface 102 of the power supply adapter 1, there are contacts 104 (i.e., the conductive positions on the second connection surface 102) opposite to the positions of the elastic pieces on the circuit board 3. The area of the contacts 104 is larger than the area of the positions on the corresponding elastic pieces that contact the contacts 104. The contacts 104 are used for electrically connecting with the elastic pieces on the corresponding circuit board 3. Through the arrangement of the contacts 104 on the power supply adapter 1, it is ensured that the elastic pieces on the circuit board 3 can be accurately and stably welded to the power supply adapter 1, and even without precise alignment, a stable connection state can be maintained between the battery 2 and the circuit board 3.

[0058] In the actual connection state, it is only necessary that the elastic pieces on the circuit board 3 can contact and connect with the contacts 104 to realize the transmission of current.

[0059] In an optional embodiment of the present utility model, the power supply adapter 1 can be a power supply adapter circuit board. A power supply circuit is arranged inside the power supply adapter circuit board. The power supply circuit connects the pads 103 on the first connection surface 101 and the contacts 104 on the second connection surface 102, so that power can be supplied to the circuit board 3 through the battery 2 and the power supply adapter 1.

[0060] Among them, a circuit protection module (such as existing overcurrent protection modules, overvoltage protection modules, etc.) can be arranged in the power supply circuit to achieve the function of protecting the circuit. The specific circuit protection module is not limited here.

[0061] In an optional embodiment of the present utility model, as Figures 1 to 4 shown, the length direction of the power supply adapter 1 inside the electronic price tag is perpendicular to the thickness of the electronic price tag, and multiple batteries 2 are arranged in sequence along the length direction of the power supply adapter 1, so that the installation and connection of the battery 2 and the power supply adapter 1 can be carried out within the minimum height space (i.e., the space in the thickness direction of the electronic price tag), which helps to reduce the thickness of the formed electronic price tag and is more conducive to the installation of the electronic price tag in a small space.

[0062] In a specific embodiment given by the present utility model, as Figures 1 to 4 shown, three batteries 2 are arranged side by side on the power supply adapter 1, and the three batteries 2 are located in the same plane, so as to meet the power supply requirements of the electronic price tag. Of course, the number of batteries 2 can also be other numbers (one, two, four, or even more). The specific number of batteries 2 is not limited here, as long as the power supply requirements can be met.

[0063] In an optional embodiment of the present utility model, as Figure 1 、 Figures 5 to 8As shown, the electronic price tag includes a frame 4. Among them, the frame 4 further includes two relatively arranged first frame segments 401 and two relatively arranged second frame segments 402. The ends of two adjacent first frame segments 401 and the ends of two second frame segments 402 are detachably connected to form a quadrilateral frame structure by enclosing.

[0064] In this embodiment, a quadrilateral frame structure is formed by enclosing two relatively arranged first frame segments 401 and two relatively arranged second frame segments 402. The ends of each adjacent first frame segment 401 and the ends of the second frame segment 402 are detachably connected. During the actual assembly process, according to the different sizes of the electronic price tags to be assembled, first frame segments 401 and / or second frame segments 402 with corresponding lengths can be selected for adaptive connection, so as to meet the adaptive requirements of different-sized electronic price tags. The adjustability of the first frame segments 401 and the second frame segments 402 is stronger, thus facilitating the combination to form frames of different sizes, with convenient combined assembly, low cost and high production efficiency.

[0065] In an alternative embodiment of the present utility model, as Figure 1 、 Figures 5 to 8 shown, the first frame segments 401 and the second frame segments 402 are respectively strip-shaped. The two first frame segments 401 are arranged in parallel, the two second frame segments 402 are arranged in parallel, and the first frame segments 401 are perpendicular to the second frame segments 402, so that the enclosed quadrilateral frame 4 is rectangular.

[0066] In an alternative embodiment of the present utility model, both the first frame segments 401 and the second frame segments 402 can be made of metal materials, so that the formed frame has higher structural strength, which in turn helps to extend the durability of the product. Among them, the metal material can be but is not limited to stainless steel. In some embodiments, the first frame segments 401 and the second frame segments 402 can also be made of plastic, but it is necessary to ensure that the connection positions of the first frame segments 401 and the second frame segments 402 have sufficient strength, and the top corner positions of the formed frame are not easily damaged, and the cost can also be reduced.

[0067] Furthermore, the first frame segments 401 and / or the second frame segments 402 can be formed by numerically controlled machining (CNC) of extruded strip-shaped metal materials.

[0068] In an alternative embodiment of the present utility model, as Figures 1 to 4 、 Figure 9 、 Figure 10As shown, the electronic price tag also includes a battery fixing frame 8, which has a rectangular frame structure. The power supply adapter 1 forms at least one side of the battery fixing frame 8. Multiple batteries 2 are arranged in the battery fixing frame 8, and the pole ears of the multiple batteries 2 are respectively in contact with the power supply adapter 1; an insertion hole 406 is provided on the first frame segment 401 and / or the second frame segment 402. During assembly, the multiple batteries 2 are inserted into the frame 4 through the insertion hole 406 along with the battery fixing frame 8. After being inserted into place, the spring clip on the circuit board is just in contact with the second connecting surface 102 of the power supply adapter 1, thereby realizing the power supply requirement.

[0069] In an optional embodiment of the present invention, Figure 1 , Figure 2 , Figures 5 to 8 As shown, a first connecting protrusion 4011 is provided on the side wall of the first frame segment 401 facing the inside of the frame 4, and a second connecting protrusion 4021 is provided on the side wall of the second frame segment 402 facing the inside of the frame 4. The first frame segment 401 and the second frame segment 402 are detachably connected via the first connecting protrusion 4011 and the second connecting protrusion 4021.

[0070] The first connecting protrusion 4011 may be a strip-shaped protrusion extending uninterruptedly along the length direction of the first frame segment 401, and the second connecting protrusion 4021 may be a strip-shaped protrusion extending uninterruptedly along the length direction of the second frame segment 402, and the end of the first connecting protrusion 4011 is connected to the end of the second connecting protrusion 4021 adjacent to it; of course, if Figure 5 , Figure 7 As shown, the first connecting protrusion 4011 can also be divided into two sections and respectively set near the two ends of the first frame segment 401, and the second connecting protrusion 4021 can also be divided into two sections and respectively set near the two ends of the second frame segment 402, so as to save materials, reduce weight and reduce costs.

[0071] Further, such as Figure 5 , Figure 6 As shown, a snap-fit ​​structure 405 is provided between the first connection protrusion 4011 and the second connection protrusion 4021, and the first frame segment 401 and the second frame segment 402 are connected by the snap-fit ​​structure 405. The snap-fit ​​structure 405 includes a snap-fit ​​groove and a protrusion that is snap-fitted with the snap-fit ​​groove. The protrusion can be provided at the end of the first connection protrusion 4011, and the snap-fit ​​groove can be provided at the edge of the second connection protrusion 4021. The protrusion is snap-fitted into the snap-fit ​​groove to form a gourd buckle positioning structure, so as to achieve the positioning and installation of the first frame segment 401 and the second frame segment 402. Of course, the positions of the protrusion and the snap-fit ​​groove can also be interchanged, that is, the snap-fit ​​groove is provided at the end of the first connection protrusion 4011, and the protrusion is provided at the edge of the second connection protrusion 4021.

[0072] Further, the card slot can be a through slot with an internal cross-sectional area larger than the cross-sectional area at the opening of the card slot. The protrusion can be embedded in the card slot by means of lateral sliding (i.e., as shown in Figure 6 , the protrusion is inserted into the card slot in a direction perpendicular to the paper surface inward or outward). After the protrusion is embedded in the card slot, it can only be separated from the card slot by lateral sliding, and other angles are locked, so as to ensure the stability of the connection between the first frame segment 401 and the second frame segment 402.

[0073] Further, as shown in Figure 7 , Figure 8 , a connecting plate 404 is provided between the first connecting protrusion 4011 and the second connecting protrusion 4021. The connecting plate 404 covers the surface of the position where the protrusion is clamped with the card slot, and the connecting plate 404 is riveted and fixed to the first connecting protrusion 4011 and the second connecting protrusion 4021 respectively. Through the arrangement of the connecting plate 404, the stability of the connection between the first connecting protrusion 4011 and the second connecting protrusion 4021 is further improved, and the connecting plate 404 can play a role in laterally blocking the protrusion embedded in the card slot, avoiding the lateral slippage of the protrusion relative to the card slot, and further ensuring the stability of the connection between the first frame segment 401 and the second frame segment 402.

[0074] Further, as shown in Figure 8 , the connecting plate 404 is in an "L" shape. The connecting plate 404 can extend from the first connecting protrusion 4011 on the first frame segment 401 to the second connecting protrusion 4021 on the second frame segment 402, so as to fixedly connect the connection position between the first connecting protrusion 4011 on the first frame segment 401 and the second connecting protrusion 4021 on the second frame segment 402. Among them, the connection manner between the connecting plate 404 and the first connecting protrusion 4011 and the second connecting protrusion 4021 can be but is not limited to riveting, and other fixing methods can also be used, as long as it can ensure the stable connection between the connecting plate 404 and the first connecting protrusion 4011 and the second connecting protrusion 4021 respectively.

[0075] In an alternative embodiment of the present utility model, as shown in Figure 6 , Figure 8 , Figure 9As shown, mounting holes 403 are formed on the frame 4. The mounting holes 403 are located at positions near the ends on the first frame segment 401 and / or the second frame segment 402. The mounting holes 403 are through holes. Among them, the mounting holes 403 are threaded holes. Through the arrangement of the mounting holes 403, the installation and fixation requirements of the electronic price tag in different scenarios can be realized. For example, a hanging part of a bolt steel wire can be inserted into the mounting hole 403 at the top of the frame 4. The bolt steel wire passes through the mounting hole 403, and then the electronic price tag is suspended and installed at a preset position through the hanging part. Another example is that a screw can be screwed into the mounting hole 403 at the bottom of the frame 4. The screw is arranged on the display stand, realizing the assembly of the electronic price tag and the display stand, so that the electronic price tag can be placed on a preset position such as a desktop.

[0076] In an alternative embodiment of the present utility model, as Figure 9 shown, the electronic price tag further includes a rear cover (not shown), a support plate 5, a display screen 7 and a front frame 6. The support plate 5 is fixedly arranged inside the frame 4 (or the frame 4 is fixedly arranged around the outer periphery of the support plate 5). The circuit board 3 is arranged on the support plate 5. The rear cover is located on the back of the support plate 5 and is connected to the frame 4. The display screen 7 and the front frame 6 are sequentially arranged in front of the support plate 5, and the front frame 6 is connected to the frame 4. The front frame 6 fixes and presses the display screen 7 between the front frame 6 and the support plate 5 to form a single-sided screen display structure of the electronic price tag. Among them, the signal receiving end of the display screen 7 is electrically connected to the signal output end of the circuit board 3 to transmit the information to be displayed to the display screen 7, and the display screen 7 displays the commodity information.

[0077] In an alternative embodiment of the present utility model, as Figure 9 shown, the electronic price tag further includes two support plates 5, two display screens 7 and two front frames 6. The two support plates 5 are stacked and spaced inside the frame 4. Circuit boards 3 are respectively arranged on the two support plates 5. The display screens 7 and the front frames 6 are respectively arranged on the sides away from each other of the two support plates 5 in sequence. The two front frames 6 are respectively connected to the frame 4 to form a double-sided screen display structure of the electronic price tag. Compared with the single-sided screen electronic price tag, the electronic price tag with the double-sided screen display structure can display commodity information on both sides, has a higher structural space utilization rate. In the scenario where commodity information needs to be displayed on both sides of the electronic price tag, the electronic price tag with the specific double-sided screen display structure of the present utility model can be used, without setting two single-sided display electronic price tags, having a wider applicable scenario and a better display effect.

[0078] Specifically, in this embodiment, the two support plates 5, the two display screens 7 and the two front frames 6 are symmetrically arranged. Therefore, the production molds of the frame 4, the support plate 5, the display screen 7 and the front frame 6 in the double-sided screen display structure can be shared with those in the single-sided screen display structure, which is convenient for production and reduces costs.

[0079] The features and advantages of the electronic price tag of the present utility model are as follows:

[0080] First, in this electronic price tag, the power supply adapter 1 is added to connect the tabs of multiple batteries 2 to the circuit board 3, realizing the connection of multiple batteries 2. This not only meets the power supply requirements of the electronic price tag, but also the setting of the power supply adapter 1 can reserve a large area of PAD area for the connection of the spring pieces on the circuit board 3. This connection method does not require precise alignment of the spring pieces, and the power supply connection of the battery can be achieved within the relatively small height space inside the electronic price tag.

[0081] Second, the frame 4 of this electronic price tag is assembled by splicing two first frame segments 401 and two second frame segments 402. According to the different sizes of the electronic price tags to be assembled, the first frame segments 401 and / or the second frame segments 402 with corresponding lengths can be selected, so as to meet the adaptation requirements of different sizes of electronic price tags. The adjustability of the first frame segments 401 and the second frame segments 402 is stronger, which is convenient for assembling different-sized outer frames, with convenient combined assembly, low cost and high production efficiency.

[0082] Third, in this electronic price tag, by setting mounting holes 403 on the frame 4, the installation and fixing requirements such as hanging and placing the electronic price tag in different scenarios can be met.

[0083] Fourth, this electronic price tag can be set as a double-sided screen display structure, which is applicable to scenarios with double-sided display requirements, ensuring better display effects, and the structure is symmetrical. Therefore, the single-sided screen display structure and the double-sided screen display structure can share the mold, which is convenient for production and reduces costs.

[0084] The above are only the illustrative specific embodiments of the present utility model, and are not intended to limit the scope of the present utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present utility model shall fall within the scope of protection of the present utility model.
