Description

Electronic shelves

The present invention relates to a shelf, and in particular to an electronic shelf.

The existing electronic tag includes a battery, a computing module, a communication module, a display module, and a power management module. The power management module can supply power to the computing module, the communication module, and the display module through the battery, and the computing module receives an external signal through the communication module to adjust the screen of the display module.

However, the computing module needs to frequently control the communication module to confirm the reception and transmission of external signals, but the display module actually needs to adjust the screen at a very low frequency, resulting in power consumption in existing electronic tags. Furthermore, due to the extremely low frequency of display module adjustment, the number of effective operations of the computing module and the communication module will also be very small, highlighting the low cost-effectiveness of the computing module and the communication module.

Therefore, the inventors of the present invention believe that the above defects can be improved, and have conducted intensive research and applied scientific principles to finally propose the present invention which has a reasonable design and effectively improves the above defects.

Referring to FIGS. 1 to 10 , the present embodiment provides an electronic shelf 100. As shown in FIG. 1 , the electronic shelf 100 comprises a display stand 1, a plurality of serial electronic label display modules 2 disposed on the display stand 1, a power supply module 3 electrically coupled to the plurality of serial electronic label display modules 2, and a control module 4 electrically coupled to the plurality of serial electronic label display modules 2 and the power supply module 3. Next, the components of the electronic shelf and their connection relationships are introduced below.

As shown in FIGS. 1 and 4 , the display stand 1 includes a bracket 11 and a plurality of shelves 12 disposed on the bracket 11. Each shelf 12 extends from a side of the bracket 11, and the shelf 12 can be used to place a plurality of display commodities (not shown). In practice, each shelf 12 includes a groove body G on a side away from the bracket 11, and the groove body G is U-shaped and has an opening facing the top of the bracket 11, and an outer wall G11 and an inner wall G12 spaced apart, and the groove body G can accommodate part of the serial electronic label display module 2 to achieve the purpose of installation (as shown in FIG. 5 ).

As shown in FIGS. 2 to 4 , the plurality of serial electronic tag display modules 2 are respectively disposed on a side of each of the shelves 12 away from the bracket 11, and each of the serial electronic tag display modules 2 can present a plurality of display screens (not shown). Specifically, each of the serial electronic tag display modules 2 in this embodiment includes a mounting member 21 and a plurality of electronic tag displays 22 disposed on the mounting member 21.

The mounting member 21 is made of an elastic material (e.g., elastic plastic, elastic metal, etc.), and includes a support platform 211, an elastic ear 212 connected to the support platform 211, and an outer cover 213 pivotally connected to the support platform 211. The support platform 211 can be mounted on the shelf 12 through the elastic ear 212, so that the support platform 211 can carry a plurality of the electronic tag displays 22. The outer cover 213 can pivot relative to the support platform 211, so that the outer cover 213 can cover a plurality of the electronic tag displays 22 (as shown in FIG. 6 ).

In detail, as shown in FIGS. 4 to 6 , the support platform 211 has a receiving portion 2111, a supporting portion 2112, and a pivot portion 2113. The cross-section of the receiving portion 2111 is generally in a closed shape (e.g., circular, rectangular, or other polygonal), so that the receiving portion 2111 can selectively accommodate wires or other components as needed. Furthermore, a plurality of mounting holes H2111 are provided on a side of the receiving portion 2111 facing the plurality of electronic tag displays 22, and the plurality of mounting holes H2111 can be penetrated by the mounting posts of the plurality of electronic tag displays 22, so that the plurality of electronic tag displays 22 can be stably fixed on the support platform 211. The support portion 2112 extends from the bottom of the receiving portion 2111 in a direction away from the bracket 11 and is roughly hook-shaped, and the support portion 2112 has the pivot portion 2113 at the end away from the elastic hanging ear. When multiple electronic tag displays 22 are set on the supporting platform 211, the receiving portion 2111 (part of it) and the support portion 2112 can jointly abut against the multiple electronic tag displays 22, and the pivot portion 2113 can install the outer cover 213.

In addition, the elastic hanging ear 212 extends from one side of the supporting platform 211 (the accommodating portion 2111 toward the supporting portion 2112), and the elastic hanging ear 212 and the supporting platform 211 are spaced apart from each other to form a accommodating gap GP. The elastic hanging ear 212 can be accommodated in the groove-shaped trough body G through the opening of the groove-shaped trough body G, so that the outer wall G11 is accommodated in the accommodating gap GP. Accordingly, when the elastic hanging ear 212 is in the groove-shaped trough body G, the outer wall G11 can be abutted against by the portion of the supporting platform 211 in the accommodating gap GP and the portion of the elastic hanging ear 212 in the accommodating gap GP, so that the mounting member 21 is fixed on the shelf 12.

In one embodiment, as shown in FIG. 5 , the receiving portion 2111 of the support platform 211 has a contact surface S on one side away from the supporting portion 2112 and adjacent to the elastic hanging ear 212. The cross-section of the elastic hanging ear 212 is roughly in the shape of an inverted U (with the opening facing downward), and the end portion of the elastic hanging ear 212 is a long structure extending toward the contact surface S. The extension line L212 of the elastic hanging ear 212 is parallel to and close to the contact surface S, so that the distance between the end portion of the elastic hanging ear 212 and the contact surface S is preferably not greater than the thickness of the outer wall G11. In addition, the elastic hanging ear 212 and the abutting surface S are spaced apart from each other to have an entrance connected to the accommodating gap GP.

Accordingly, when the elastic hanging ear 212 is installed in the groove-shaped tank body G, the outer wall G11 can extend into the accommodating gap GP through the entrance, and the elastic hanging ear 212 pushes the outer wall G11 against the abutment surface S through its elastic force, so that the mounting member 21 is fixed on the groove-shaped tank body G of the shelf 12. In other words, the outer wall G11 is fixed by the side of the elastic hanging ear 212 away from the bracket and the abutment surface S.

In another embodiment, as shown in FIG. 7 , the cross-section of the elastic hanging ear 212′ is U-shaped, and the elastic hanging ear 212′ has two mutually spaced abutting portions 2121 and a connecting portion 2122 connecting the two abutting portions 2121, and the elastic hanging ear 212′ has an opening between the two abutting portions 2121 facing upward from the bracket 11. The spacing distance between the two abutting portions 2121 is substantially equal to the spacing distance between the inner wall G12 and the outer wall G11 of the groove body G. Accordingly, when the elastic ear 212' is installed in the groove-shaped trough body G, the two abutting portions 2121 can abut against the outer wall G11 and the inner wall G12 of the groove-shaped trough body G, so that the mounting member 21 is fixed on the groove-shaped trough body G of the shelf 12.

In addition, one of the abutting portions 2121 is adjacent to the abutting surface S but not in contact with it, so that a clamping gap for the accommodating notch GP can be formed between one of the abutting portions 2121 and the abutting surface S, and the width of the clamping gap (i.e., the spacing distance between one of the abutting portions 2121 and the abutting surface S) is preferably not greater than the thickness of the outer wall G11 (or is slightly greater than the thickness 1 of the outer wall G11). Accordingly, when the two abutting portions 2121 of the elastic hanging ear 212' abut against the outer wall G11 and the inner wall G12, one of the abutting portions 2121 can further push the outer wall G11 to move toward the abutting surface S, so that one of the abutting portions 2121 can cooperate with the abutting surface S to clamp the outer wall G11.

Referring again to FIG. 2 , the plurality of electronic tag displays 22 are electrically connected in series, and each of the electronic tag displays 22 has the display screen. In practice, the plurality of electronic tag displays 22 can be grouped in three, and the three electronic tag displays 22 can be connected in series with each other via a flexible cable. In addition, two adjacent groups of electronic tag displays 22 can also be connected in series via a flexible cable. Accordingly, when any one (or any group) of the electronic tag displays 22 malfunctions or is damaged, the user can quickly disassemble one (or one of the groups) for repair and replacement.

5 and 6, the outer cover 213 is pivotally connected to the pivot portion 2113 of the support platform 211, and includes a buckle portion 2131, a plurality of visible portions 2132, and an elastic supporting portion 2133. Specifically, the plurality of visible portions 2132 can be transparent windows or exposed holes, and each visible portion 2132 has opposite ends. The buckle portion 2131 is connected to one end of the plurality of visible portions 2132 facing the pivot portion 2113, and the cross-section of the buckle portion 2131 is substantially C-shaped so as to be buckled on the pivot portion 2113, so that the outer cover 213 can pivot relative to the elastic hanging ear 212 with the pivot portion 2113 as the axis. The elastic supporting portion 2133 is connected to one end of the plurality of visible portions 2132 away from the pivot portion 2113. The elastic supporting portion 2133 is generally V-shaped in this embodiment, and the elastic supporting portion 2133 can support the elastic hanging ear 212 and the inner wall G12 located in the groove-shaped tank body G through elastic force to limit the pivoting of the outer cover 213. When the elastic supporting portion 2133 limits the pivoting of the outer cover 213, the outer cover 213 can cover multiple electronic tag displays 22, and the positions of multiple visible portions 2132 correspond to the display screens of multiple electronic tag displays 22, but the present invention is not limited thereto.

For example, when the elastic hanging ear 212 (and the supporting platform 211) are in different forms (for example, the elastic hanging ear 212' in Figure 7), the elastic supporting portion 2133 can also be supported in the opening of the elastic hanging ear 212, so that the elastic supporting portion 2133 supports the two supporting portions 2121 to limit the pivoting of the outer cover 213.

Accordingly, each of the serial electronic label display modules 2 can achieve the effects of rapid installation, replacement, maintenance, and adjustment through the above-mentioned structure.

Referring again to FIG. 1 , the power supply module 3 is disposed on the lower side of the display stand 1 in this embodiment, and the power supply module 3 can provide electric energy. The control module 4 in this embodiment has functional elements such as communication, calculation, and storage, and the control module 4 is electrically coupled to the power supply module 3 and the plurality of the serial electronic label display modules 2 to uniformly perform multiple controls. Specifically, the control module 4 can obtain the electric energy to transmit to the plurality of the serial electronic label display modules 2, and the control module 4 receives an adjustment signal wirelessly (or wired), and further forwards it to the plurality of the serial electronic label display modules 2 to correct each of the display screens of any of the serial electronic label display modules 2.

That is, the multiple serial electronic label display modules 2 of the present invention share the same control module 4 to perform communication, calculation, storage and other functions, but the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the multiple serial electronic label display modules 2 may also have storage components, so that each performs data storage.

In addition, in order to achieve the goal of net zero carbon emissions, the electronic shelf 100 of the present invention further uses solar energy as an energy source. Specifically, the power supply module 3 also includes a plurality of solar panels 31, a maximum power point tracker 32 electrically coupled to the plurality of solar panels 31, and a storage device 33 electrically coupled to the maximum power point tracker 32. Among them, the plurality of solar panels 31 are arranged on the display stand 1 and can perform a photoelectric conversion, and the maximum power point tracker 32 can adjust the power of the photoelectric conversion to supplement the electrical energy of the storage device 33, but the present invention is not limited to this. For example, the electronic shelf 100 can also be provided with electricity through city electricity, wind power, or other methods.

Preferably, as shown in FIG9 and FIG10 , in order to prevent each solar panel 31 from being blocked by the plurality of layers 12 and affecting the efficiency of the photoelectric conversion, the display stand 1 includes an extension frame 13 and a top plate 14. The extension frame 13 extends from the top end of the support 11, the top plate 14 is arranged on the extension frame 13, and the plurality of solar panels 31 are arranged on the top plate 14.

In addition, each solar panel 31 may still be blocked by the environment, so the extension frame 13 also includes two rails 131, two slides 132, and two limit rods 133, so as to achieve the effect of flexibly adjusting the height of multiple solar panels 31. Specifically, the two rails 131 are fixed to the bracket 11 at intervals, and each rail 131 has a plurality of positioning holes H131. The two slides 132 are respectively installed on the two rails 131, and the two slides 132 jointly support the top plate 14. The two slides 132 can move along the two rails 131 to adjust the height position of the top plate 14 relative to the bracket 11. Each of the sliding members 132 has a plurality of through holes H132 corresponding to the plurality of positioning holes H131 . Each of the limiting rods 133 can pass through one of the corresponding positioning holes H131 and the through hole H132 , so that the limiting rod 133 limits the movement of the sliding member 132 along the track 131 .

In addition, in some environments, the light source is not located directly above the display stand 1. Therefore, in order to more effectively capture the light source, the electronic shelf 100 of the present invention can adjust the angle of the multiple solar panels 31 so that any solar panel 31 is not parallel to the shelf 12 but can face the light source. For example, in one embodiment, the top panel 14 can be pivoted on the extension frame 13, and the top panel 14 can be pivoted relative to the shelf 12 to face the light source, so that the multiple solar panels 31 located on the top panel 14 can effectively capture the light source. In another embodiment, the plurality of solar panels 31 are pivoted on the top plate 14, and the plurality of solar panels 31 can be pivoted relative to the top plate 14 to face the light source. In yet another embodiment, a plurality of pivot plates (not shown) are mounted on the top plate 14, and a plurality of the solar panels 31 are mounted on the pivot plates respectively, and the plurality of the pivot plates can be pivoted relative to the top plate 14 to face the light source, so that the solar panels 31 on each pivot plate can effectively capture the light source.
