[0064] Box 200. Detailed Implementation

[0065] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0066] The following is for reference. Figures 1-11 Description of the indicating device 100 and storage device 1000 according to embodiments of this application.

[0067] like Figure 1 As shown, the indicating device 100 of this application embodiment is applicable to a storage device 1000, which includes upright refrigerators, vending machines, automatic vending cabinets, and upright freezers, etc. The storage device 1000 includes an indicating device and a housing 200. The housing 200 is used to store items, and the indicating device is used to provide information to the user; the information type is not limited to advertisements, product identification, functional prompts, etc.

[0068] In related technologies, the indicating device can only achieve a single indicating effect, has poor light stability, and its display effect is poor and not aesthetically pleasing. When the indicating device is used to achieve diverse and dynamic display effects of graphic elements, the structure of the indicating device is designed to be more complex, which increases the production and design cost. Furthermore, the content indicated by the indicating device cannot be changed according to user needs. When users have personalized needs for the indicating content, the overall structure of the indicating device needs to be redesigned, resulting in high production and design costs.

[0069] Therefore, in this embodiment of the application, an indicator device 100 with a simple structure and capable of achieving various lighting effects is designed.

[0070] like Figure 2 and Figure 3 As shown, the indicating device 100 of this application embodiment includes: an inner shell assembly 1, a first light source 3, a light-emitting assembly 2, and an outer shell 4.

[0071] Among them, such as Figure 4 As shown, the inner shell assembly 1 forms a first mounting groove 114 and a second mounting groove 115. The front end of the first mounting groove 114 is open, and the second mounting groove 115 is disposed around the first mounting groove 114. The light-emitting assembly 2 is mounted in the first mounting groove 114, and the first light source 3 is mounted in the second mounting groove 115.

[0072] The inner shell assembly 1 can block and concentrate light, so that the light emitted by the light-emitting assembly 2 can only pass through the open end of the first mounting groove 114.

[0073] The second mounting groove 115 is disposed around the first mounting groove 114. For example, the second mounting groove 115 extends along the extension direction of the first mounting groove 114 to form an annular groove; or, the second mounting groove 115 includes a plurality of second mounting grooves, which are spaced apart around the first mounting groove 114 in the circumferential direction.

[0074] The light-emitting component 2 is used to form and display the indication content. The inner shell component 1 and the light-emitting component 2 can be quickly detached and replaced to make it easier to change the indication information content of the indicator device 100, which is conducive to realizing more personalized customization needs of users.

[0075] like Figure 4 As shown, the first light source 3 and the inner shell assembly 1 are detachably connected for easier replacement, facilitating maintenance and replacement of the indicator information content of the indicator device 100.

[0076] The front end of the second mounting slot 115 is open or is provided with a light-transmitting material baffle. The first light source 3 is installed in the second mounting slot 115 so that the light emitted by the first light source 3 can only pass through the front side of the second mounting slot 115.

[0077] The first light source 3 can display different or the same lighting effects as the light-emitting component 2. For example, the two can display different colors, different frequencies, or different indicator information to increase the eye-catching effect.

[0078] For example, the first light source 3 can be a marquee, and the light-emitting component 2 can be an indicator light, a constant light, or a combination thereof.

[0079] like Figure 5 As shown, the outer shell 4 forms a third mounting groove 46 with an open front end, and the inner shell assembly 1 is mounted in the third mounting groove 46.

[0080] The outer shell 4, inner shell assembly 1 and light-emitting assembly 2 are arranged sequentially from the outside to the inside. The outer shell 4 is located at the outermost layer of the indicator device 100 and serves a decorative function.

[0081] The outer shell 4 can be a metal part or an injection molded part. For example, the outer shell 4 can be made of metals such as aluminum alloy, plated aluminum or stainless steel. The outer shell 4 can also be an injection molded part that can present a metallic effect.

[0082] For example, the outer shell 4 can be molded to resemble an aluminum alloy.

[0083] In this embodiment, the inner shell assembly 1 can be pushed into the third mounting groove 46 from the open front end of the third mounting groove 46 to assemble with the outer shell 4.

[0084] For example, the light-emitting component 2 can be assembled with the inner shell component 1 first, and then the inner shell component 1 with the light-emitting component 2 installed can be assembled with the outer shell 4; or, the inner shell component 1 can be assembled with the outer shell 4 first, and then the light-emitting component 2 can be assembled with the inner shell component 1.

[0085] According to the indicator device 100 provided in this application, by setting the light-emitting component 2 and the first light source 3, the light-emitting component 2 and the first light source 3 can have different lighting effects, thereby achieving a variety of lighting effects and improving the eye-catching effect of the indicator device 100; at the same time, by setting the outer shell 4, which is located on the outermost layer of the indicator device 100, the outer shell 4 can play a decorative and fixing role, thereby improving the aesthetics of the indicator device 100 and extending the life of the indicator device 100.

[0086] In some embodiments, such as Figure 5 and Figure 7 As shown, at least one snap-fit ​​groove 43 is provided on the inner side of the outer shell 4, the opening of the snap-fit ​​groove 43 faces the front side of the outer shell 4, and at least a portion of the inner shell assembly 1 is located in the snap-fit ​​groove 43.

[0087] The snap-fit ​​groove 43 serves to limit and fix the inner shell component 1, and can also act as a reinforcing rib to increase the structural strength of the outer shell 4.

[0088] The snap-fit ​​groove 43 is used to snap into the inner shell assembly 1. The opening of the snap-fit ​​groove 43 faces the front side. The inner shell assembly 1 can be pushed into the third mounting groove 46 from the open end of the front end of the third mounting groove 46 until the rear end of the inner shell assembly 1 is inserted into the snap-fit ​​groove 43 and resists the snap-fit ​​groove 43. The inner shell assembly 1 and the outer shell 4 are then assembled.

[0089] The structure of the card slot 43 includes at least the following:

[0090] Firstly, such as Figure 7 As shown, there can be multiple snap-fit ​​slots 43, which are spaced apart along the circumference of the outer shell 4. The rear end of the inner shell assembly 1 forms a multi-point connection with the multiple snap-fit ​​slots 43, thereby increasing the stability of the connection.

[0091] For example, such as Figure 7 As shown, when the outer shell 4 has multiple faces, there can be multiple snap-fit ​​slots 43 and the number of snap-fit ​​slots 43 is the same as the number of faces of the outer shell 4. The snap-fit ​​slots 43 on each side wall of the outer shell 4 extend along the extension direction of the side wall where they are located, so that there are snap-fit ​​slots 43 on each face that are connected to the inner shell assembly 1, thereby increasing the stability of the connection.

[0092] For example, the outer shell 4 is a cuboid with four side walls. The snap-fit ​​groove 43 has four grooves and is located on the four side walls of the outer shell 4 in a one-to-one correspondence. Each snap-fit ​​groove 43 extends along the extension direction of the side wall in which it is located.

[0093] Secondly, there can be one snap-fit ​​groove 43. One snap-fit ​​groove 43 extends along the side wall of the outer shell 4 to form an annular groove connected end to end. The rear end of the inner shell assembly 1 is located in the annular groove, which provides good connection stability.

[0094] In some embodiments, the cross-sectional area of ​​the opening of the snap-fit ​​groove 43 is greater than the cross-sectional area of ​​the bottom of the snap-fit ​​groove 43.

[0095] In this embodiment, as Figure 7 As shown, the cross-sectional area of ​​the front end of the snap-fit ​​groove 43 is larger than the cross-sectional area of ​​the rear end of the snap-fit ​​groove 43, so that the inner shell assembly 1 can be inserted from the slot of the snap-fit ​​groove 43.

[0096] In some embodiments, such as Figure 7 As shown, the outer shell 4 includes a body 41 and a snap-fit ​​member 42 connected to the body 41. The snap-fit ​​member 42 and the body 41 of the outer shell 4 form a snap-fit ​​groove 43.

[0097] The snap-fit ​​part 42 includes a snap-fit ​​part 11112 and a connecting part. The connecting part is connected to the inner surface of the side wall of the body 41 of the outer shell 4 and extends in a direction away from the side wall. The snap-fit ​​part 11112 is connected to one end of the connecting part away from the body 41 of the outer shell 4 and extends in a direction towards the front of the indicator device 100. The snap-fit ​​part 11112, the connecting part and the side wall of the body 41 of the outer shell 4 form a snap-fit ​​groove 43.

[0098] The snap-fit ​​portion 11112 and the connecting portion form an "L" shape. The distance from the front end of the snap-fit ​​portion 11112 to the side wall of the outer shell 4 body 41 where the snap-fit ​​member 42 is located is greater than the distance from the rear end of the snap-fit ​​portion 11112 to the side wall of the outer shell 4 body 41 where the snap-fit ​​member 42 is located, so that the inner shell assembly 1 can be inserted from the slot of the snap-fit ​​groove 43.

[0099] In some embodiments, such as Figure 3 As shown, the outer shell 4 includes a first shell portion 44 and a second shell portion 45 that are detachably connected, and the first shell portion 44 and the second shell portion 45 form a third mounting groove 46.

[0100] The first shell part 44 and the second shell part 45 can be connected by means of snap-fit, plug-in or threaded connection.

[0101] In this embodiment, by setting the first shell portion 44 and the second shell portion 45 as a separate structure, different specifications of the first shell portion 44 and the second shell portion 45 can be selected according to the size specifications of the inner shell assembly 1, so as to adapt to storage devices 1000 of different specifications and inner shell assemblies 1 of different lengths.

[0102] For example, such as Figure 3 As shown, the first shell portion 44 and the second shell portion 45 have the same structure. The first shell portion 44 and the second shell portion 45 are half shells of the outer shell 4. Both the first shell portion 44 and the second shell portion 45 have a U-shaped structure. The first shell portion 44 and the second shell portion 45 are connected to form the third mounting groove 46.

[0103] For example, the first shell portion 44 and the second shell portion 45 have different structures. For instance, the first shell portion 44 is one-third of the shell portion along the length direction of the outer shell 4, and the second shell portion 45 is two-thirds of the shell portion along the length direction of the outer shell 4. The first shell portion 44 and the second shell portion 45 are connected to form the third mounting groove 46.

[0104] In some embodiments, such as Figure 6 As shown, the indicating device 100 also includes a connecting fastener, and the first housing portion 44 and the second housing portion 45 are connected by the connecting fastener.

[0105] For example, such as Figure 6As shown, a portion of the connecting fastener overlaps with the first shell portion 44, and another portion of the connecting fastener overlaps with the second shell portion 45. The connecting fastener is provided with a first through hole corresponding to the first shell portion 44 and a second through hole corresponding to the second shell portion 45. The threaded fastener shell is respectively inserted into the first through hole and the second through hole to connect the first shell portion 44 and the second shell portion 45.

[0106] For example, the fastener can be a snap-fit ​​connection assembly, in which one of the first housing portion 44 and the second housing portion 45 is provided with a snap, and in which one of the first housing portion 44 and the second housing portion 45 is provided with a retaining ring, and the first housing portion 44 and the second housing portion 45 are connected by the snap-fit ​​connection assembly.

[0107] In some embodiments, the fasteners are also used to connect to the storage device 1000.

[0108] The fasteners are equipped with a connection structure for connecting to the storage device 1000. The connection structure can be a through hole, a snap fastener, or a plug-in connector.

[0109] Among them, such as Figure 4 and Figure 6 As shown, the connecting fasteners include an upper fastener 51 and a lower fastener 52. The upper fastener 51 is located above the indicator device 100, and the lower fastener 52 is located below the indicator device 100. The structures of the upper fastener 51 and the lower fastener 52 can be the same or different.

[0110] In some embodiments, such as Figure 4 and Figure 6 As shown, the upper fastener 51 is a flat plate structure and has a through hole for connecting with the storage device 1000. The lower fastener 52 is a bent plate structure and includes a first bent portion and a second bent portion. The first shell portion 44 and the second shell portion 45 are connected through the first bent portion. The second bent portion is bent downward relative to the first bent portion and is used to insert with the storage device 1000.

[0111] In this embodiment, by setting the upper fastener 51 and the lower fastener 52 to different structures, the upper fastener 51 can be threadedly fastened to the storage device 1000 after the lower fastener 52 is inserted and positioned with the storage device 1000, thereby reducing the assembly difficulty and increasing the stability of the connection between the two.

[0112] In some embodiments, such as Figure 6 As shown, the rear end of the outer shell 4 is provided with a flange, which folds inward toward the third mounting groove 46. The third mounting groove 46 is used to abut against the storage device 1000 and can increase the structural strength of the outer shell 4.

[0113] In some embodiments, such as Figure 6 As shown, the flange on the lower side of the outer shell 4 has a clearance for the lower fastener 52, so as to facilitate the assembly of the lower fastener 52 and the outer shell 4 and increase the connection stability.

[0114] In some embodiments, such as Figure 3 As shown, the inner shell assembly 1 includes: a main shell 11 and an outer trim 12; the main shell 11 forms a first mounting groove 114 and a second mounting groove 115; the outer trim 12 is installed in the groove of the first mounting groove 114.

[0115] In this embodiment, the exterior trim 12 is located on the front side of the main housing 11 and serves a decorative function. The exterior trim 12 can be a metal part or an injection molded part. For example, the exterior trim 12 can be made of metals such as aluminum alloy, plated aluminum, or stainless steel. The exterior trim 12 can also be an injection molded part that can present a metallic effect.

[0116] The number of exterior trim pieces 12 can be one or more. One exterior trim piece 12 can extend circumferentially around the opening of the first mounting groove 114 to form an annular trim strip. Multiple exterior trim pieces 12 can be distributed circumferentially around the opening of the first mounting groove 114.

[0117] In some embodiments, the exterior trim 12 and the exterior shell 4 have the same appearance. For example, both the exterior trim 12 and the exterior shell 4 have an aluminum alloy effect, or both have a gold effect, or both have an orange effect.

[0118] The exterior trim 12 and the exterior shell 4 can be made of different materials.

[0119] In some embodiments, such as Figure 4 As shown, the inner shell assembly 1 includes: an inner shell layer 111, an outer shell layer 112, and a front end plate 113; the inner shell layer 111 forms a first mounting groove 114; the outer shell layer 112 is spaced apart from the inner shell layer 111 to form a second mounting groove 115; the front end plate 113 is connected to the front side of the inner shell layer 111 and the front side of the outer shell layer 112, at least a portion of the front end plate 113 forms the bottom of the second mounting groove 115, and the exterior trim 12 is mounted on the front end plate 113.

[0120] The inner shell assembly 1 forms a first mounting groove 114 and a second mounting groove 115 through the double-layer arrangement of the inner shell layer 111 and the outer shell layer 112, so that the first light source 3 and the light-emitting component 2 can be installed at the same time, so that the indicator device 100 can display different lighting effects.

[0121] The first mounting slot 114 and the second mounting slot 115 are separated by an inner shell layer 111. The inner shell layer 111 has a light-blocking effect, which can reduce the interference between the light emitted by the first light source 3 and the light-emitting component 2, so that the first light source 3 and the light-emitting component 2 can present independent lighting effects.

[0122] Part or all of the front end plate 113 forms the bottom of the second mounting groove 115, that is, the front side of the second mounting groove 115 is closed and the rear end of the second mounting groove 115 is open, so as to facilitate the assembly of the first light source 3 with the second mounting groove 115.

[0123] Among them, such as Figure 4 As shown, the front end plate 113 includes a light-transmitting surface 1131, which forms at least part of the bottom of the second mounting groove 115, and the outer side of the light-transmitting surface 1131 is connected to the outer shell layer 112.

[0124] In this embodiment, since the front side of the second mounting groove 115 is closed, the front end plate 113 is provided with a light-transmitting surface 1131 with a light-transmitting effect, which can both allow the light emitted by the first light source 3 to pass through the front side of the second mounting groove 115 and protect the first light source 3.

[0125] The light-transmitting surface 1131 can be made of dark-colored, low-transparency acrylic material with a light transmittance between 7% and 10%. When the first light source 3 does not emit light, the color of the light-transmitting surface 1131 itself can cover the structure inside the second mounting groove 115, increasing aesthetics.

[0126] Among them, the light-transmitting surface 1131 can be flat, which has a better display effect.

[0127] In some embodiments, such as Figure 4 As shown, the front end of the outer shell layer 112 protrudes outward from the front end of the inner shell layer 111 in the front-back direction. The front end plate 113 includes: a flow guiding slope 1132, the outer peripheral side of the flow guiding slope 1132 is connected to the light-transmitting surface 1131, the flow guiding slope 1132 is inclined toward the first mounting groove 114, the flow guiding slope 1132 is inclined inward in the direction away from the first mounting groove 114, and the outer trim 12 is installed on the flow guiding slope 1132.

[0128] As a result, the open end structure of the first mounting groove 114 is formed into a shape that gradually expands from the inside to the outside, and the transition between the guide slope 1132 and the light-emitting component 2 on the appearance surface of the indicator 100 is smoother, which improves the aesthetics of the appearance of the indicator 100.

[0129] Furthermore, the guide slope 1132 located above the open end of the first mounting groove 114 can also block direct sunlight from shining on the light-emitting component 2, improving the service life of the indicator 100, or block rainwater in rainy weather, preventing rainwater from accumulating on the light-emitting component 2 and affecting the information display of the indicator 100. The guide slope 1132 located below the open end of the first mounting groove 114 can also achieve a guiding function, guiding rainwater dripping onto the front surface of the indicator 100 to the outside of the first mounting groove 114 in rainy weather, preventing rainwater from accumulating and affecting the information display of the indicator 100.

[0130] In some embodiments, such as Figure 4 As shown, the first light source 3 has a first connector; a second connector 1133 is provided on the rear side of the front end plate 113 and is detachably connected to the first connector.

[0131] One of the first connector and the second connector 1133 can be a socket, and the other of the first connector and the second connector 1133 can be a pin. The first light source 3 and the rear side of the front end plate 113 can be quickly disassembled and connected through the pin socket, which facilitates the replacement and maintenance of the first light source 3.

[0132] In some embodiments, the first light source 3 has an insertion hole, and the rear side of the front end plate 113 is provided with a pin. The pin includes a first pin and a second pin, which are distributed in the front-rear direction. The outer diameter of the first pin is larger than the outer diameter of the second pin, and the insertion hole is adapted to the second pin.

[0133] The first pin serves to limit and fix the first light source 3, reducing the risk of damage and disruption to the lighting display effect caused by the first light source 3 being too close to the front panel 113.

[0134] In some embodiments, such as Figure 4 and Figure 9 As shown, an elastic clip 1111 is provided on the rear side of the inner shell layer 111. The elastic clip 1111 is adapted to deform in the direction close to the outer shell layer 112 under the action of external force so that the light-emitting component 2 is assembled with the first mounting groove 114, and abuts against the light-emitting component 2 after the light-emitting component 2 is assembled with the first mounting groove 114.

[0135] In this embodiment, by providing the elastic clip 1111, the deformation capability of the elastic clip 1111 can be utilized to facilitate the assembly of the light-emitting component 2 and the inner shell component 1, and can increase the stability of the connection between the light-emitting component 2 and the inner shell component 1.

[0136] In some embodiments, such as Figure 8 As shown, multiple elastic clips 1111 are provided, and the multiple elastic clips 1111 are distributed circumferentially around the inner shell layer 111 to form a multi-point connection between the inner shell layer 111 and the light-emitting component 2, thereby increasing the stability of the connection between the inner shell layer 111 and the light-emitting component 2.

[0137] In some embodiments, such as Figure 9As shown, the elastic clip 1111 includes a deformable part 11111 and a snap-fit ​​part 11112. The deformable part 11111 is connected to the inner shell layer 111. The snap-fit ​​part 11112 is located at the rear end of the deformable part 11111 and includes a snap-fit ​​surface 11113 and a guide surface 11114. The snap-fit ​​surface 11113 faces the front and is used to abut against the light-emitting component 2. The guide surface 11114 faces the first mounting groove 114, and the distance between the guide surface 11114 and the outer shell layer 112 is monotonically constant from front to back.

[0138] In this embodiment, by providing a guide surface 11114, it is easy to assemble the light-emitting component 2 with the first mounting groove 114. By providing a snap-fit ​​surface 11113, it can abut against the light-emitting component 2 to increase the stability of the connection between the light-emitting component 2 and the inner shell component 1.

[0139] In some embodiments, such as Figure 4 As shown, the light-emitting component 2 includes: a lamp housing 21, a second light source 22, a display panel 23, and at least one light-blocking component 24.

[0140] Optionally, the lamp housing 21 can be an open structure at one end along its length or an open structure on both sides along its length, or an open structure at one end along its front and back or an open structure on both sides along its front and back. The lamp housing 21 only needs to be open on one side to achieve quick assembly and disassembly of the second light source 22, the display panel 23, and the light shield 24.

[0141] Among them, such as Figure 4 As shown, the lamp housing 21 forms a fourth mounting groove 211 with an opening. The second light source 22, the display panel 23, and the light shield 24 are all mounted in the fourth mounting groove 211. In the direction close to the opening of the fourth mounting groove 211, that is, in the direction from the inside to the outside of the fourth mounting groove 211, the second light source 22 is located at the innermost side of the fourth mounting groove 211 and faces the opening of the fourth mounting groove 211. The lamp housing 21 can block and concentrate the light, so that the light emitted by the second light source 22 can only pass through the opening of the fourth mounting groove 211. Before the light passes through the opening of the fourth mounting groove 211 and is processed and guided by the display panel 23 and the light shield 24, the corresponding indication content will be displayed.

[0142] The lamp housing 21 has a third connector that connects to the inner housing assembly 1. The third connector can be a plug-in or a card.

[0143] The display panel 23 is located on the outermost side. The display panel 23 can be installed in the opening of the fourth mounting groove 211. The display panel 23 can be located inside the fourth mounting groove 211 defined by the lamp housing 21, with the opening closed inside the fourth mounting groove 211. Alternatively, the display panel 23 can be located outside the fourth mounting groove 211 defined by the lamp housing 21, with the opening closed outside the fourth mounting groove 211.

[0144] As light passes through the display panel 23, some of the light is blocked by the display panel 23 and cannot pass through. The display panel 23 is provided with at least one first mark 231, and light can pass through at the position corresponding to the first mark 231. Thus, the indicator device 100 can display a light and shadow shape with the same shape as the first mark 231 to the outside world, thereby better conveying the indicator information to the user.

[0145] The light-blocking element 24 is sandwiched between the second light source 22 and the display panel 23, and the light-blocking element 24 surrounds the first mark 231. The number of light-blocking elements 24 can correspond to the number of first marks 231. That is, when there is one first mark 231, the indicator device 100 includes one light-blocking element 24, and the light-blocking element 24 surrounds the first mark 231. When there are multiple first marks 231, the light-blocking element 24 includes multiple light-blocking elements 24, which are the same number as the number of first marks 231, and the multiple light-blocking elements 24 are arranged to surround the multiple first marks 231 in a one-to-one correspondence.

[0146] The light-blocking component 24 improves light stability, ensuring that the second light source 22 illuminates the corresponding first sign 231, thus enabling controllable illumination of the signs on the display board 23. This prevents the second light source 22 corresponding to the first sign 231 from illuminating other signs on the display board 23, which could cause incorrect indication information. Because the illumination of the signs on the display board 23 is controllable, the indicator device 100 can conveniently achieve diverse and dynamic display effects for various graphic elements.

[0147] The light-blocking component 24 is sandwiched between the second light source 22 and the display panel 23, meaning that the light-blocking component 24 is tightly fitted to both the second light source 22 and the display panel 23. This prevents light from leaking out through gaps between the light-blocking component 24 and the second light source 22 or between the light-blocking component 24 and the display panel 23, thus avoiding interference with the display effect of the light and shadow during the indication process of the indicating device 100. Before installing the indicating device 100, the light-blocking component 24 can be pre-fixed to the display panel 23 and / or the second light source 22 to ensure the accuracy and stability of the light-blocking component 24's position and prevent deviations in its position during installation.

[0148] The light-blocking component 24 can be pre-fixed to the display panel 23 and / or the second light source 22 by means of adhesive bonding, so as to achieve the connection between the light-blocking component 24 and the display panel 23 and / or the second light source 22 without damaging the structure of the display panel 23 and / or the second light source 22. The light-blocking component 24 and the second light source 22 can also be pre-fixed by means of snap-fit ​​connection to improve the stability of the connection between the two.

[0149] In some embodiments, the light-emitting component 2 further includes a light-transmitting element.

[0150] The light-transmitting element is installed on the side of the display panel 23 away from the light-blocking element 24, and closes the opening of the fourth mounting groove 211. The light-transmitting element can be located inside the fourth mounting groove 211 defined by the lamp housing 21, with the opening closed inside the fourth mounting groove 211; alternatively, the light-transmitting element can be located outside the fourth mounting groove 211 defined by the lamp housing 21, with the opening closed on the outside of the fourth mounting groove 211. The placement of the light-transmitting element serves two purposes: firstly, it protects the internal structure of the fourth mounting groove 211 from external influences and wear on the information on the display panel 23; secondly, it prevents external substances from entering the fourth mounting groove 211 and corroding the internal second light source 22, thus affecting the service life of the indicating device 100.

[0151] The display panel 23 can be made of film, on which different display advertisements and display images can be made according to user needs. The use of film allows the display panel 23 to display rich colors and delicate tones, making the indicator device 100 look more upscale. The display panel 23 can be attached to the light-transmitting component and installed simultaneously with the light-transmitting component.

[0152] In some embodiments, the light-transmitting element is made of dark-colored, low-transparency acrylic material with a light transmittance between 7% and 10%. When the second light source 22 is not emitting light, the color of the light-transmitting element itself can obscure the logo pattern on the display panel 23. At the same time, the light-transmitting element can also isolate external sunlight from the internal structure of the fourth mounting groove 211, improving the weather resistance of the internal structure of the fourth mounting groove 211 under sunlight.

[0153] In other embodiments, the light-transmitting element may be integrally formed with the lamp housing 21 to form an open portion of the structure, thereby improving the sealing performance and aesthetic appearance of the indicator device 100. Alternatively, the light-transmitting element may be formed as a coating on the outer surface of the display panel 23, etc., without limitation.

[0154] Furthermore, the content indicated by the indicator 100 can be customized according to user needs. The content indicated by the indicator 100 can be changed simply by replacing the display panel 23, thus reducing production and design costs.

[0155] In some embodiments, such as Figure 11 As shown, the display panel 23 is provided with multiple first identifiers 231, and there are multiple light-blocking elements 24. Each of the multiple light-blocking elements 24 corresponds to one of the multiple first identifiers 231. For example, in the illustrated embodiment, the display panel 23 is provided with four first identifiers 231, namely “Haier”, “Smart”, “Retail” and “Terminal”. There are also four light-blocking elements 24, which respectively surround the four first identifiers 231.

[0156] The display panel 23 is provided with a second mark 232, which is located outside the light shield 24. For example, in the illustrated embodiment, the display panel 23 is provided with a second mark 232, which is a gradient dot mark whose size gradually decreases from the center to the periphery, except for the letter part.

[0157] Due to the arrangement of the light-blocking element 24, light from the inner and outer sides of the light-blocking element 24 is not mutually transmitted. The lamp group located inside the orthogonal projection of the light-blocking element 24 onto the second light source 22 can only control the brightness of the first mark 231 corresponding to the light-blocking element 24, and will not illuminate the second mark 232 located outside the light-blocking element 24 or the first mark 231 corresponding to other light-blocking elements 24. The lamp group located outside the orthogonal projection of the light-blocking element 24 onto the second light source 22 can illuminate the second mark 232 located outside the light-blocking element 24 and control the brightness of the second mark 232, but will not illuminate the first mark 231 located inside the light-blocking element 24.

[0158] In some embodiments, such as Figure 10 and Figure 11 As shown, the light-blocking component 24 is modeled after the first mark 231. The light-blocking component 24 is disposed around the first mark 231 and is modeled after the outer contour of the first mark 231.

[0159] For example, such as Figure 10 and Figure 11 As shown, the first identifier 231 is “Haier”, and the light-blocking component 24 is shaped to resemble the outer contour of “Haier”; the first identifier 231 is “Smart”, and the light-blocking component 24 is shaped to resemble the outer contour of “Smart”.

[0160] In this embodiment, since a light-blocking component 24 that mimics the shape of the first identifier 231 is provided, the light on the inner and outer sides of the light-blocking component 24 is not mutually transmitted, thereby better isolating the light of the corresponding first identifier 231, other first identifiers 231 and second identifiers 232, resulting in a higher sense of technology and better lighting effects.

[0161] Furthermore, in order to achieve diverse and dynamic display effects of graphic elements, the second light source 22 includes multiple light groups. By controlling the on / off state of the multiple light groups, the on / off state of each sign on the indicator device 100 can be controlled, thereby achieving diverse and dynamic display effects of graphic elements.

[0162] Specifically, the inner and outer sides of the orthographic projection of the light-blocking member 24 onto the second light source 22 correspond to different light groups. The different light groups are set to be independently controlled to open and close. Thus, the independent opening and closing of different light groups can be controlled as needed, the illumination of each mark on the indicator device 100 can be controlled, and the indication information of the indicator device 100 can be controlled.

[0163] In some embodiments, the first light source 3 includes multiple light groups. By controlling the brightness and color of the multiple light groups, the display effect of the first light source 3 on the indicator device 100 can be controlled, thereby achieving a variety of dynamic display effects of light elements.

[0164] The system can control the first light source 3 and the second light source 22 to display the same color light, but with different dynamic effects.

[0165] For example, the first light source 3 can be displayed as a dynamic marquee light effect to enhance its eye-catching effect, and the second light source 22 can be displayed as a constant light effect to enhance its indication effect.

[0166] Among them, such as Figure 11 As shown, the display panel 23 has four first logos 231, namely "Haier", "Smart", "Retail" and "Terminal". There are four light-blocking elements 24, which surround the four first logos 231 respectively, and form second logos 232 that are gradually decreasing in size from the center to the periphery. The second light source 22 corresponds to five different light groups, which can be independently controlled to turn on and off. Specifically, the opening and closing of the first light group controls the brightness of the first logo 231 "Haier", the opening and closing of the second light group controls the brightness of the first logo 231 "Smart", the opening and closing of the third light group controls the brightness of the first logo 231 "Retail", the opening and closing of the fourth light group controls the brightness of the first logo 231 "Terminal", and the opening and closing of the fifth light group controls the brightness of the second logo 232, that is, the brightness of the gradual light dots. The storage device 1000 can control the independent illumination of any one of the four first signs 231 and second signs 232 without affecting the illumination of the other signs. At the same time, it can control the display effect of the first light source 3 without affecting the display effect of the second light source 22. By controlling the different signs of the second light source 22 and the illumination changes of the first light source 3, the technological feel of the device can also be improved.

[0167] The content of the first identifier 231 can be replaced as needed, for example, with a welcome sign such as "Welcome" or "Thank you for your patronage", or with a status sign that can display the current status of the storage device 1000 such as "Purchasing", "Checking out", or "In malfunction", or with an advertising slogan or product name, etc., without any limitation.

[0168] In some embodiments, such as Figure 4 As shown, the light-emitting component 2 also includes a rear shell 25, which is detachably connected to the lamp housing 21 and forms the bottom of the fourth mounting groove 211.

[0169] The rear shell 25 is used to seal the lamp housing 21, so that the light emitted by the second light source 22 can only pass through the opening of the fourth mounting slot 211.

[0170] The rear shell 25 and the lamp housing 21 are connected by snap-fit, plug-in or threaded connection. With the rear shell 25 open relative to the lamp housing 21, the second light source 22, display panel 23 and light shield 24 can be pushed from the open end of the rear side of the lamp housing 21 into the fourth mounting groove 211 to assemble with the lamp housing 21. After assembly, the rear shell 25 and the lamp housing 21 can be assembled, simplifying the assembly method.

[0171] This application embodiment also provides a storage device 1000, including: a housing 200 and an indicator 100 as described in any of the above embodiments. The indicator 100 is installed in the housing 200, which is used to accommodate the electrical structure inside the storage device 1000 and to define a storage space for storage.

[0172] The storage device 1000 is made more technologically advanced and improves the user experience by setting up an indicator device 100 that can display various dynamic graphic elements.

[0173] Reference Figure 1 The enclosure 200 includes a main enclosure, an electrical box, and a door. The main enclosure forms a compartment where items can be stored, providing storage within the compartment. The door is located on the main enclosure and installed on the front of the main enclosure for opening or closing the compartment.

[0174] The compartments can be configured as a normal temperature room, a cold storage room, or a freezer room. The normal temperature room can be cooled to form a cold storage room, the cold storage room can be further cooled to form a freezer room, and the freezer room can be heated to form a cold storage room.

[0175] Specifically, in some embodiments, the storage room device is a vending machine, and the storage device 1000 can be a vending machine with a refrigeration system. The refrigeration system is used to provide cooling to the room so that the temperature of the room is suitable for below zero degrees Celsius. During this time, the items in the room are frozen, and the room constitutes a freezer.

[0176] The refrigeration system provides cooling to the compartments to maintain a temperature between 0 and 9 degrees Celsius, at which point the compartments function as cold storage compartments. When the refrigeration system is not operating, the compartments function as ambient temperature compartments.

[0177] The electrical box is installed on the top of the main enclosure, and the door is installed on the main enclosure and rotatably positioned at the front of the main enclosure. When the door is closed, the door is parallel to the front surface of the main enclosure. The indicator device 100 is installed on the enclosure 200 at the front of the electrical box and above the closed door, so as to achieve installation without changing the overall size and volume required for the installation of the storage device 1000. The indicator device 100 is located at the top front of the storage device 1000, which is also beneficial for displaying information to people at a distance and also covers the electrical box at the rear, improving the aesthetics of the storage device 1000.
