Description

Technical Field

[0001] The present invention relates to the technical field of display boxes, and in particular to a lighting display box. Background Art

[0002] Display boxes are usually used to store and display various figurines, toys, handicrafts, etc., or to store shoes, etc. Existing display boxes are usually made of transparent materials. In order to improve the display effect, lights are usually arranged in the display boxes to illuminate and improve the viewing experience.

[0003] As the demand for display becomes higher and higher, it is necessary for display boxes to be stackable and meet the circuit connectivity requirements between display boxes. In the prior art, CN 214650013 U discloses a stackable display box, which is spliced ​​by card slots and card blocks, but the circuit is connected through an external power cord. This exposed power cord makes the display box look unsightly; in the prior art, CN 210455925U discloses a smart shoe box, which is electrically connected by a concave first electrode and a convex second electrode. Compared with the exposed power cord, it is slightly more beautiful, but the convex and concave design requires that the box body surface be kept clear of air to achieve stacking, which increases the difficulty of processing the shell.

[0004] In addition, the lights in the current display box are usually illuminated vertically downward from the top. However, due to the cone-shaped emission characteristics of the light itself, if only one lighting lamp is installed on the top of the display box, a large dark area will appear in the display box, affecting the lighting and display effects. In order to solve this problem, a large number of lamp beads are generally arranged on the top of the display box to increase the bright area and weaken the dark area. However, within the 2cm-3cm illumination range close to the lamp bead light source, there will still be a dark area at the distance between the lamp beads, showing a phenomenon of alternating light and dark. See Fig.19 The area within the dotted circle in the middle is a dark area. The existence of this dark area is a technical barrier that cannot be overcome at present. In order to solve this problem, a light homogenizing plate is generally added below the light source, and the light homogenizing plate should be located below the dark area. As a result, there is a large space between the light source and the light homogenizing plate, and the lamp beads need to be arranged very densely to achieve the light homogenizing effect. This not only increases the thickness of the lamp board, but also increases the number of lamp beads arranged, resulting in a complex structure and high cost. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a lighting display box which can automatically meet the requirements of signal and power connection and uniform lighting when stacked and spliced.

[0006] In order to solve the above technical problems, the technical solution of the present invention is: a light display box, comprising: A box body, comprising a top plate, a bottom plate, a front plate, a rear plate, a left plate, and a right plate; a circuit substrate, a plurality of control modules arranged on the circuit substrate, and a plurality of conductive sockets electrically connected to the control modules in a one-to-one correspondence are arranged inside the box body; the conductive sockets are arranged at the edge of the box body, and a plurality of connector openings corresponding to the conductive sockets are arranged on the outer surface of the box body; the circuit substrate is installed in the front edge of the top plate, a plurality of lamp beads are arranged on the circuit substrate along the length direction, and a uniform light diffusion component used in conjunction with the lamp beads is also arranged at the bottom of the top plate, and the lamp beads are irradiated from the front end of the uniform light diffusion component to the rear side; At least one conductive connector is inserted into the connector opening and is detachably connected to the corresponding conductive socket, so as to realize splicing, fixation and electrical connection between the two box bodies when the two box bodies are stacked.

[0007] As a preferred technical solution, the uniform light diffusion component includes a reflective film, a diffuser plate, and a uniform light plate arranged in sequence from top to bottom, and the plurality of lamp beads are arranged on the front end surface of the diffuser plate, and the lamp beads irradiate from the front end to the rear side of the diffuser plate.

[0008] As a preferred technical solution, the reflective film, the diffuser plate, and the light homogenizer are fixed to the top plate by bolts.

[0009] As a preferred technical solution, auxiliary reflective films are provided on the left and right edge end surfaces of the diffuser plate.

[0010] As a preferred technical solution, there are two conductive sockets, and the two conductive sockets are arranged correspondingly on the left and right sides of the top plate. The two ends of the conductive connector are respectively inserted into the conductive sockets on the adjacent sides of the left and right box bodies to achieve splicing, fixation and electrical connection between the adjacent box bodies on the left and right.

[0011] As a preferred technical solution, two conductive sockets are provided, and the two conductive sockets are arranged correspondingly up and down, one of the conductive sockets is arranged at the rear of the top plate, and the other conductive socket is arranged at the bottom of the rear plate, and the two ends of the conductive connector are respectively inserted into the conductive sockets on the adjacent sides of the upper and lower box bodies to achieve splicing, fixation and electrical connection between the upper and lower adjacent box bodies.

[0012] As a preferred technical solution, the conductive socket located at the bottom of the rear plate is connected to the corresponding control module through a conductive adapter structure, and the conductive adapter structure is arranged between the top plate and the rear plate.

[0013] As a preferred technical solution, the conductive adapter structure includes an adapter plate 1 and an adapter plate 2, wherein the adapter plate 1 is disposed at the rear of the top plate and is electrically connected to the corresponding control module, and the adapter plate 2 is disposed at the top of the rear plate and is electrically connected to the conductive socket located at the bottom of the rear plate, and the adapter plate 1 and the adapter plate 2 are electrically connected via a conductive spring pin.

[0015] As a preferred technical solution, magnets are provided on the left and right sides of the box body, and the magnets on the adjacent sides of any two adjacent left and right box bodies are arranged to be attracted to each other.

[0016] Due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The stacking of display boxes uses conductive connectors as a connection medium. By plugging and unplugging the conductive connectors and contacting the corresponding conductive sockets inside the display boxes, it not only realizes conductivity and signal transmission, but also allows the left, right, top and bottom arrangement of the display boxes to have a certain limit, and the structural design is ingenious; in addition, the two sides of the conductive connector can be fully inserted into the interior of the display box, and the insertion stroke is large, which not only enables the display boxes to be firmly plugged in on the left, right, top and bottom, but also does not require additional grooves or bumps on the outside of the display box.

[0017] 2. The lamp beads are arranged on the inner surface of the front side of the top plate, and irradiate from the front end of the diffuser plate to the rear side, thereby realizing the effect of front lighting. Since the dark area between the lamp beads is close to the front side of the top plate, the front edge of the top plate can be cleverly used to physically shield the existing dark area, just cleverly avoiding the dark area visible to the human eye, so that the dark area cannot be seen under normal viewing angles (looking straight, looking down, and looking sideways), and the area that people can observe from the outside is evenly bright. This design method of front lighting cleverly utilizes the structural characteristics of the top plate of the display box, arranges the light source position reasonably, and utilizes the superposition of light-guiding materials, so that the light effect of the light display box can be ideally presented, amazing the user's visual experience.

DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention are described only by way of illustration. Needless to say, those of ordinary skill in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0020] like Figure 1 and Figure 2 As shown, a light display box includes a box body 100 and a conductive connector 200. The conductive connector 200 serves as a connector for horizontally or vertically splicing two box bodies 100. The connector can not only realize the splicing and fixation between the two box bodies 100, but also realize the electrical connection between the two box bodies 100 for power supply and signal transmission.

[0021] Located inside the box body 100, there are provided a circuit substrate 107, a plurality of control modules 108 arranged on the circuit substrate 107, and a plurality of conductive sockets 109 electrically connected to the control modules 108 in a one-to-one correspondence. The conductive sockets 109 are arranged at the edge of the box body 100 to facilitate plug-in fixation, and a plurality of connector openings 110 corresponding to the conductive sockets 109 are provided on the outer surface of the box body 100. The connector openings 110 are used to facilitate the insertion of the conductive connector 200.

[0022] The conductive connector 200 is an accessory of the box body 100. It is inserted into the connector opening 110 and detachably connected to the corresponding conductive socket 109. When two box bodies 100 are stacked, the two box bodies 100 are spliced, fixed, and electrically connected. There is at least one conductive connector 200. Of course, the specific number is related to the number of display boxes to be spliced. When two display boxes are spliced, only one conductive connector 200 is used to connect the two display boxes; when three display boxes are spliced, two conductive connectors 200 are used to connect between two adjacent display boxes; when four display boxes are spliced, three conductive connectors 200 are used to connect between two adjacent display boxes, and so on. See the diagram of the state after stacking. Fig.11 The plug-in principle of the conductive plug connector 200 is shown in Fig.12 .

[0023] In this embodiment, in addition to realizing the splicing, fixing and electrical connection between the two display boxes, the conductive connector 200 can also be used as a power supply terminal. Since the conductive connector 200 itself has a conductive function, when half of it is inserted into the corresponding box body 100 and the corresponding conductive socket 109, the other half of the conductive connector 200 exposed outside the box body 100 can also be used as a power supply terminal, and can be connected to a power supply through an adapter such as USB for power supply. At this time, the display box connected to the power supply serves as a master device, and the other display boxes serve as slave devices. Therefore, when the conductive connector 200 needs to be used as a power supply terminal, it is necessary to select one of the multiple spliced ​​display boxes as the master device, and insert an additional conductive connector 200 into one of the vacant connector openings 110 of the master device, and the half of the conductive connector 200 exposed outside serves as a power supply terminal, which is used to connect to the power supply as a power supply terminal. Of course, a socket dedicated to connecting to a power cord may also be provided on the display box. In this case, the conductive connector 200 is only used to realize the splicing, fixation and electrical connection between adjacent display boxes.

[0024] In this embodiment, the number of the conductive sockets 109 can be arranged in pairs, with one on each side for horizontal splicing, one on each side for vertical splicing, or one on each side for horizontal and vertical splicing. The number of the conductive connectors 200 is at least one, which is used to splice the left and right boxes 100, or to splice the upper and lower boxes. The specific number required depends on the number of boxes 100 to be spliced.

[0025] In this embodiment, a conductive socket 109 is respectively provided at the end faces of both sides of the box body 100, and the two conductive sockets 109 are correspondingly arranged on the left and right sides. The two ends of the conductive connector 200 are respectively inserted into the conductive sockets 109 on the adjacent sides of the left and right box bodies 100 to achieve splicing, fixation and electrical connection between the adjacent box bodies 100 on the left and right sides.

[0026] In this embodiment, a conductive socket 109 is respectively provided at the upper and lower end surfaces of the box body 100, and the two conductive sockets 109 are correspondingly arranged up and down, and the two ends of the conductive connector 200 are respectively inserted into the conductive sockets 109 on the adjacent sides of the upper and lower box bodies 100 to achieve splicing, fixation and electrical connection between the upper and lower adjacent box bodies 100.

[0027] In this embodiment, the box body 100 includes a top plate 101, a bottom plate 102, a front plate 103, a rear plate 104, a left plate 105, and a right plate 106, and the six panels are assembled by splicing, see Figure 3 Since each panel is detachable and assembled, and in order to ensure a reasonable structural layout, the circuit substrate 107 is arranged on the front inner surface of the top plate 101 of the box body 100, as a PCB integrated main board in the box body 100, which is not only used to install the control module 108 to realize the electrical connection of the device, but also can be used to install lamp beads or other modules that realize touch function and display function, so as to meet the purpose of circuit integration.

[0028] In order to ensure convenient connection, the conductive sockets 109 on the left and right sides are arranged on the left and right sides of the top plate 101, and the conductive sockets 109 on the left and right sides are respectively connected to the corresponding control modules 108 through lines, the conductive sockets 109 on the upper side are arranged at the rear of the top plate 101, and are connected to the corresponding control modules 108 through lines, and the conductive sockets 109 on the lower side are arranged at the bottom of the rear plate 104. Since the rear plate 104 and the top plate 101 are detachably spliced, the conductive sockets 109 located at the bottom of the rear plate 104 need to be connected to the corresponding control module 108 through a conductive adapter structure 111, and the conductive adapter structure 111 is arranged between the top plate 101 and the rear plate 104. Of course, if the panels of the box body 100 are non-detachable structures, then the conductive sockets 109 can be directly preset inside the box body 100, and the position does not have to be limited to the top plate 101.

[0029] The number of the conductive sockets 109 corresponds to the control modules 108 one by one, and they are directly or indirectly connected through lines.

[0030] See also Figures 6 to 8The conductive transfer structure 111 includes a transfer conductive plate 1 111a and a transfer conductive plate 2 111b. The transfer conductive plate 1 111a is disposed at the rear of the top plate 101 and is electrically connected to the corresponding control module 108 through a line. The transfer conductive plate 2 111b is disposed at the top of the rear plate 104 and is electrically connected to the conductive socket 109 at the bottom of the rear plate 104 through a line. The transfer conductive plate 1 111a and the transfer conductive plate 2 111b are electrically connected through a plurality of conductive elastic pins 111c. In this embodiment, the conductive elastic pins The fixed end of the conductive pin 111c is installed on the transfer conductive plate 1 111a. When the top plate 101 and the rear plate 104 are panel-joined, the head end of the conductive spring pin 111c abuts against the transfer conductive plate 2 111b, thus realizing the electrical connection between the transfer conductive plate 1 111a and the transfer conductive plate 2 111b. At this time, the conductive socket 109 located at the bottom of the rear plate 104 is electrically connected to the corresponding control module 108 through the transfer conductive plate 2 111b, the conductive spring pin 111c, and the transfer conductive plate 1 111a. The transfer conductive plate 1 111a is fixed on the front plate 103, and the transfer conductive plate 2 111b is fixed on the rear plate 104. The head end of the conductive spring pin 111c is elastic, which can ensure that the panel can be stably connected to the transfer conductive plate 2 111b after panel jointing. The first transfer conductive plate 111a and the second transfer conductive plate 111b are both PCB boards, which are used to realize the transmission of power and signals.

[0031] See also Fig. 9 and Fig.10 The conductive socket 109 includes a conductive plate 109a, which is electrically connected to the corresponding control module 108. A conductive spring 109b for pressing the conductive connector 200 is provided on the conductive plate 109a. A limit support plate 109c is provided below the conductive spring 109b. A connector channel for fixing the conductive connector 200 is formed between the conductive spring 109b and the limit support plate 109c. The conductive spring 109b is a key component for fixing the conductive connector 200. It adopts V-shaped metal elasticity and cooperates with the limit support plate 109c to press and fix the conductive connector 200. At the same time, it also plays a conductive role as a medium for power and signal transmission between the conductive plate 109a and the conductive connector 200. The conductive plate 109a is a PCB board, which is used to realize the transmission of power and signals.

[0032] The connector opening 110 and the conductive socket 109 are not located on the same panel. Fig.10When the conductive socket 109 is arranged on the top plate 101, the connector opening 110 is arranged on the left plate 105 or the right plate 106; when the conductive socket 109 is arranged on the rear plate 104, the connector opening 110 is arranged on the bottom plate 102, and the corresponding limiting support plate 109c is arranged on the connector opening 110, which is used in conjunction with the conductive spring sheet 109b to achieve the purpose of clamping and fixing the conductive connector 200.

[0033] The conductive plug-in 200 is a PCB plug-in board, and the plug-in opening 110 corresponds to the PCB plug-in board. Using a PCB board as a conductive plug-in board, on the one hand, the PCB board itself has good strength, and after being plugged and fixed by the PCB board, the connection strength is high and the stability is good; on the other hand, the PCB board itself has the functions of conducting electricity and transmitting signals, so it is better to use a PCB board as a conductive plug-in board, and it has the effects of plugging and fixing and electrical connection.

[0034] In order to further ensure the plug-in stability, magnets 112 are provided on the left and right sides of the box body 100. The magnets 112 on the adjacent sides of any two adjacent left and right boxes 100 are arranged to be adsorbed to each other, and the adsorption of the magnets 112 is used as a structure to assist in improving the connection stability between the display boxes. Since the conductive sockets 109 on the left and right sides are provided on the top plate 101, located at the top of the box body 100, the magnets 112 are provided at the bottom of the box body 100.

[0035] The stacking of display boxes uses the PCB board itself as a connection medium. By plugging and unplugging the PCB board and contacting the corresponding PCB board inside the display box, it not only realizes electrical conduction and signal transmission, but also allows the left, right, top and bottom arrangement of the display boxes to have a certain limit, and the structural design is ingenious; in addition, since the PCB board itself has good strength and both sides of the PCB board can be completely inserted into the interior of the display box with a large insertion stroke, it can not only realize the left, right, top and bottom plug-in of the display box to be firmly connected, but also there is no need to add grooves or bumps outside the display box, which can ensure that the appearance of the display box is intact, and the two adjacent display boxes can be stacked without gaps, and the product appearance and usage experience can reach the best.

[0036] In order to achieve the lighting effect inside the display box, a number of lamp beads 113 are arranged along the length direction on the circuit substrate 107, and a uniform light diffusion component 114 used in conjunction with the lamp beads 113 is also provided at the bottom of the top plate 101. The lamp beads 113 are irradiated from the front end of the uniform light diffusion component 114 to the rear side. The uniform light diffusion component 114 is specifically arranged in a cavity opened at the bottom of the top plate 101, and a retaining edge for surrounding the uniform light diffusion component 114 is provided around the top plate 101.

[0037] See also Figures 13 to 17The uniform light diffusion component 114 includes a reflective film 114a, a diffuser plate 114b, and a uniform light plate 114c arranged from top to bottom in the cavity of the top plate 101. A plurality of lamp beads 113 are arranged along the length direction on the front end surface of the diffuser plate 114b. The lamp beads 113 irradiate from the front end of the diffuser plate 114b to the rear side.

[0038] The lamp beads 113 are arranged on the front inner surface of the top plate 101, and irradiate from the front end of the diffuser plate 114b to the rear side, achieving the effect of front lighting. Since the dark area between the lamp beads 113 is close to the front side of the top plate 101, the front side edge of the top plate 101 can be cleverly used to physically shield the existing dark area, just cleverly avoiding the dark area that can be seen by the human eye (the position of the dark area is shown in FIG. Fig.18 The circle area pointed by the middle arrow) makes it impossible to see the dark area under normal viewing angles (looking straight, looking down, and looking from the side), and the area that people can observe from the outside is evenly bright. This front lighting design cleverly utilizes the structural characteristics of the display box top plate 101, arranges the light source position reasonably, and utilizes the superposition of light-guiding materials, so that the light effect of the light display box can be ideally presented, amazing the user's visual experience.

[0039] The diffuser plate 114b is arranged corresponding to the lamp bead 113, and the lamp bead 113 emits light at the front end of the diffuser plate 114b. After passing through the diffuser plate 114b, the light source of the lamp bead 113 can be evenly emitted from the front end to the rear side; and the reflective film 114a is arranged above the diffuser plate 114b to prevent the light source from overflowing and reduce the waste of the light source. At the same time, the homogenizing plate 114c is arranged below the diffuser plate 114b to make the light source in the diffuser plate 114b uniform. The combination of the reflective film 114a, the diffuser plate 114b, and the homogenizing plate 114c is combined to form a new type of light-guiding material, which can ensure that a uniform surface light source is formed at the top of the box body 100, so that the light in the display box is better evenly diffused.

[0040] In addition, the lamp beads 113 in the present device are arranged in only one row along the width direction of the display box. By using the diffuser plate 114b, the light homogenizer 114c and the reflective film 114a in combination, the linearly arranged light sources are formed into a surface light source. Compared with the prior art method of densely laying multiple rows and columns of lamp beads 113 on the top, the number of lamp beads 113 can be greatly reduced.

[0041] In this embodiment, a 0.18 mm reflective film 114a, a 3 mm diffuser 114b, and a 1 mm light homogenizer 114c are selected from top to bottom in sequence, and the three are in contact and fit together, with an overall thickness of less than 4 mm. They are directly arranged on the top plate 101, which can significantly reduce the thickness of the top plate 101. On the premise of ensuring uniform diffusion of light, the size of the display box can be reduced and the storage space of the display box can be expanded.

[0042] In order to further prevent the light source from overflowing and being wasted, auxiliary reflective films are provided on the left and right edge end surfaces of the diffuser plate 114b. Of course, an auxiliary reflective film may also be further provided on the rear edge end surface of the diffuser plate 114b. The auxiliary reflective film is used to shield the light source on the left, right and rear sides of the diffuser plate 114b to improve the utilization rate of light.

[0043] In this embodiment, a number of the lamp beads 113 are mounted on a circuit substrate 107, and the circuit substrate 107 is mounted on the inner surface of the front edge of the top plate 101, and the circuit substrate 107 is a PCB integrated board. Of course, the circuit substrate 107 can also be replaced by a light strip, in which case the lamp beads 113 are fixed on the light strip, and the light strip is mounted on the inner surface of the front edge of the top plate 101, and the light strip is then connected to the circuit through a connecting wire. In this application, the circuit substrate 107 is arranged on the front side of the top plate 101 to meet the purpose of circuit integration, so that the entire display box only needs one control circuit board, which not only realizes the arrangement of the lamp beads 113 for front lighting, but also realizes the operation of functional modes such as touch and screen display, which reduces the layout space of the display box and reduces the defects caused by the connection through the connecting wire.

[0044] See also Fig.13 and Fig.14 A limiting card slot 114d is provided on the inner surface of the front edge of the top plate 101, and the circuit substrate 107 is vertically slidably installed in the limiting card slot 114d. The limiting card slot 114d is composed of two relatively arranged L-shaped card blocks 114e. The two L-shaped card blocks 114e cooperate to limit the circuit substrate 107 to its left and right, front and back positions.

[0045] See also Fig.16 The edge of the light diffuser 114c exceeds the outside of the diffuser 114b and abuts against the bottom of the circuit substrate 107 to limit the circuit substrate 107. When the light diffuser 114c is fixed, the upper and lower positions of the circuit substrate 107 can be limited, and the circuit substrate 107 can be installed in cooperation with the limiting slot 114d. Of course, the circuit substrate 107 can also be directly fixed to the front edge of the top plate 101 by means of screws.

[0046] The reflective film 114a is fixed to the diffuser plate 114b by gluing. Double-sided tape or glue is provided on the edges of the diffuser plate 114b, and then the reflective film 114a is glued and fixed to the diffuser plate 114b, so as to facilitate installation.

[0047] See also Fig.17 The top plate 101 is provided with a limiting column 114f for limiting the diffuser plate 114b, and the diffuser plate 114b is provided with a limiting groove or a limiting hole corresponding to the limiting column 114f, so that the diffuser plate 114b can be quickly positioned on the top plate 101 for easy installation.

[0048] The reflective film 114a, the diffuser plate 114b, and the light diffuser 114c are respectively provided with mounting holes, and the top plate 101 is provided with threaded holes corresponding to the mounting holes. The light diffuser 114c is fixed to the threaded holes on the lower surface by screws passing through the mounting holes.

[0049] The upper and lower widths of the lamp beads 113 correspond to the thickness of the diffusion plate 114 b.
