[0036] The following refers to Figures 1 to 6 Describe a display box according to an embodiment of the present utility model.

[0037] As Figure 1 、 Figure 5 、 Figure 6 As shown, a display box according to an embodiment of the present utility model includes: a box body 100 and a display panel group 200. The box body 100 is provided with a cavity 101; the display panel group 200 can be installed into the cavity 101; the display panel group 200 includes a circuit board 210 and a display screen assembly provided on the circuit board 210. The circuit board 210 is provided with a light-shielding seat 230. The light-shielding seat 230 is located between the back surface of the display screen assembly and the circuit board 210 and can partially or completely block the back surface of the display screen assembly.

[0038] The light-shielding seat 230 can partially or completely block the overflow light on the back surface of the display screen assembly, thereby effectively reducing the light leakage of the display box.

[0039] In some embodiments of the present utility model, the circuit board 210 is provided with a control module of the device and is configured with corresponding mechanical buttons or touch buttons. The display box is provided with corresponding indication marks or labels to facilitate the user to adjust the parameters of the device, etc.

[0040] As Figure 4 、 Figure 5 、 Figure 6 As shown, in some embodiments of the present utility model, the display screen assembly includes a liquid crystal screen group 221 and a surface light source 222 located on the back surface of the liquid crystal screen group 221. The light-shielding seat 230 is provided with a groove 231 into which the surface light source 222 can be inserted. After the surface light source 222 is inserted into the groove 231, the light on the rear side and side of the surface light source 222 is blocked, and the light of the surface light source 222 facing the front surface of the liquid crystal screen group 221 is normally irradiated onto the liquid crystal screen group 221, which can greatly reduce the light overflow on the rear side and side of the surface light source 222, thereby effectively reducing the occurrence of light leakage.

[0041] In some embodiments of the present invention, the depth of the groove 231 is set to be greater than or equal to the thickness of the surface light source 222, so that the surface light source 222 can be completely embedded in the light shielding seat 230 to achieve a better light shielding effect.

[0042] It is conceivable that in some embodiments of the present invention, the depth of the groove 231 can be set to be smaller than the thickness of the surface light source 222, so that the groove 231 can block the back side and part of the side of the surface light source 222, and can also achieve a certain anti-light leakage effect.

[0043] Of course, in the specific implementation process, the groove 231 may not be set, and the rear side of the surface light source 222 is close to the end face of the shading seat 230. The rear side of the surface light source 222 is only shielded by the end face of the shading seat 230, which can also reduce the occurrence of light leakage.

[0044] like Figure 6 As shown, in some embodiments of the utility model, a diffuser film 223 is arranged between the liquid crystal screen group 221 and the surface light source 222 to diffuse the light irradiated by the surface light source 222 to the liquid crystal screen group 221, so that the brightness of the liquid crystal screen group 221 is uniform, the display effect is good, and the glare light is reduced. Even if there is some overflow light, it is scattered light, and will not form a glare light leakage effect, and the user experience is better.

[0045] Specifically, the light-scattering film 223 is a diffuse reflection / refractive film, which can scatter light and improve the display effect, and has a certain light-guiding effect, guiding the light to illuminate the liquid crystal panel group 221, and has a certain effect of suppressing light leakage.

[0046] In some embodiments of the present invention, the shading seat 230 is provided with a positioning structure capable of positioning the display screen assembly, so as to improve the installation accuracy of the shading seat 230 and facilitate automated production.

[0047] Specifically, in a traditional display panel, the display screen assembly is generally installed to the circuit board 210 by welding the legs. The circuit board 210 only has welding holes corresponding to the legs, which makes alignment difficult and the legs are prone to deformation, resulting in poor installation accuracy of the display screen assembly. Through the above structure, a positioning structure for positioning the display screen assembly is provided on the shading seat 230, which can greatly improve the position accuracy of the display screen assembly relative to the circuit board 210, and through the positioning structure, the display screen assembly can be conveniently placed on the shading seat 230 using automated equipment such as a manipulator, and in conjunction with an automatic welding mechanism, the automated production of the display panel group 200 can be met, with high assembly accuracy and high production efficiency.

[0048] In some embodiments of the present invention, at least one side of the positioning structure is an open structure to facilitate the placement of the display screen assembly, and can cooperate with automated equipment such as a robot to automatically complete the assembly of the display screen assembly and the circuit board 210.

[0049] As Figure 4 , Figure 5 , Figure 6 shown, in some embodiments of the present utility model, the positioning structure includes a plurality of positioning protrusions 232 extending from the main body of the light-shielding seat 230 in a direction away from the board surface of the circuit board 210. The plurality of positioning protrusions 232 form a positioning space corresponding to the outer contour of the display screen assembly, thereby completing the positioning of the display screen assembly.

[0050] Specifically, the positioning protrusion 232 can be in abutting cooperation with the outer edge or corner of the display screen assembly to position the display screen assembly. And through the above-mentioned positioning protrusion 232, an open structure can be formed in front of the light-shielding seat 230, which is convenient for the display screen assembly to be loaded from the front of the light-shielding seat 230. Cooperating with automated equipment such as a manipulator can enable the liquid crystal screen to be automatically produced, improving production efficiency and precision machining degree.

[0051] As Figure 4 , Figure 5 , Figure 6 shown, in some embodiments of the present utility model, the positioning protrusion 232 is provided with an angular positioning portion corresponding to the corner of the display screen assembly, and the display screen assembly is accurately positioned through the angular positioning portion, and the positioning effect is good.

[0052] It can be understood that, in some embodiments of the present utility model, the positioning protrusion 232 can also be set to abut against the side edge position of the display screen assembly, and the display screen assembly can also be accurately positioned.

[0053] As Figure 5 , Figure 6 shown, in some embodiments of the present utility model, the display screen assembly is configured with welding pins 224, and the welding pins 224 are welded and fixed to the circuit board 210, finally completing the display screen assembly and electrical connection.

[0054] Specifically, in the actual production process, the light-shielding seat 230 is pre-installed on the circuit board 210, and the worker or the manipulator aligns the display screen assembly and installs it into the positioning structure of the light-shielding seat 230, and finally welds the pins, then the installation of the display screen assembly can be completed, and the installation accuracy is high.

[0055] In some embodiments of the present utility model, an abutting structure is provided in the cavity 101. The display panel group 200 can be inserted into the cavity 101, and the abutting structure can abut against two board surfaces of the display panel group 200, thereby installing the display panel group 200 into the cavity 101 and realizing the rapid installation of the display panel group 200.

[0056] As Figure 3As shown, in some embodiments of the present utility model, the abutting structure includes a first positioning rib group 110 and a second positioning rib group 120 disposed in the cavity 101. The first positioning rib group 110 and the second positioning rib group 120 can respectively abut against two plate surfaces of the circuit board 210, thereby positioning the position of the circuit board 210.

[0057] Specifically, the first positioning rib group 110 and the second positioning rib group 120 may include multiple positioning ribs to abut against the circuit board 210 at multiple points, improving the stability of positioning, being convenient for installation, and having high assembly efficiency.

[0058] It can be understood that, in some embodiments of the present utility model, insertion slots may also be provided on both side walls of the cavity 101. Both side edges of the circuit board 210 can be inserted into the insertion slots and abutted, and the display board group 200 can also be conveniently installed into the cavity 101.

[0059] As Figure 3 shown, in some embodiments of the present utility model, one side portion of the box body 100 is an outer plate 130 corresponding to the display surface of the display board group 200. The first positioning rib group 110 is disposed on the inner side of the outer plate 130 and extends towards the inner side direction of the cavity 101. An installation positioning portion 140 is provided in the box body 100, and at least part of the second positioning rib group 120 is disposed on the installation positioning portion 140 and extends towards the first positioning rib group 110, so that the first positioning rib group 110 and the second positioning rib group 120 have better structural stability and improve the stability of the installation of the display board group 200.

[0060] Specifically, the outer plate 130 is provided with a hollowed-out or light-transmitting structure corresponding to the liquid crystal screen group 221 to display the content of the screen on the outside of the display box. A display panel sticker or a painted pattern may be provided on the outside of the outer plate 130 to identify the display content or the button position. The first positioning rib group 110 is disposed on the inner side of the outer plate 130 and is located at the inner corner position of the cavity 101 and is connected to other inner walls of the cavity 101, so it has better structural strength; the box body 100 is an overall shell structure, and the installation positioning portion 140 is a columnar shell recessed into the box body 100 and is provided with installation holes for the penetration and installation of screws. The installation positioning portion 140 of the columnar shell has relatively high structural strength, and at least part of the second positioning rib group 120 is disposed at the inner corner where the installation positioning portion 140 abuts against the cavity 101, also having relatively high structural strength, thereby ensuring the stability of the positioning of the display board group 200 by the first positioning rib group 110 and the second positioning rib group 120.

[0061] As Figure 3As shown, in some embodiments of the present utility model, the first positioning rib group 110 forms a limiting structure corresponding to the display screen assembly to perform secondary positioning on the display screen assembly, so that the display screen assembly is aligned with the hollowed-out area or light-transmitting area on the outer side plate 130, ensuring the display effect.

[0062] Specifically, as Figure 3 shown, the first positioning rib groups 110 are respectively arranged on both sides of the display area 131 (hollowed-out area or light-transmitting area) of the outer side plate 130. When the circuit board 210 is inserted between the first positioning rib group 110 and the second positioning rib group 120, the positioning ribs on both sides of the hollowed-out area or light-transmitting area on the outer side plate 130 are located on both sides of the liquid crystal screen group 221, thereby accurately positioning the position of the liquid crystal screen group 221.

[0063] As Figure 7 shown, in some embodiments of the present utility model, the box body 100 is used to be installed on the cabinet body 900. The installation side of the box body 100 cooperating with the cabinet body 900 is an opening structure communicating with the cavity 101. The display board group 200 can be inserted into the cavity 101 from the opening structure of the cavity 101 and be abutted by the abutting structure. After the box body 100 is installed on the cabinet body 900, the opening structure of its cavity 101 is blocked by the cabinet body 900, and at the same time, the display board group 200 is restricted from withdrawing outwards, thereby stably installing the display board group 200 into the box body 100. The entire display board group 200 does not need to be fixed by screws or buckles, and the assembly is convenient and fast.

[0064] Specifically, as Figure 7 shown, the upper part of the box body 100 is connected to the cabinet body 900, that is, the upper part of the cavity 101 is an opening structure. The display board group 200 can be inserted into the cavity 101 from top to bottom and be abutted by the abutting structure for front-back positioning. After the box body 100 is installed on the cabinet body 900, the opening structure of the upper part of its cavity 101 is blocked by the cabinet body 900, thereby positioning the display board group 200 in the up-down direction, and thus stably installing the display board group 200 into the box body 100 with high assembly efficiency.

[0065] Of course, in the specific implementation process, the box body 100 can also be connected to the cabinet body 900 at other positions, and the position of the opening structure of the cavity 101 can be changed accordingly, which will not be elaborated here.

[0066] Referring to Figure 7 , the refrigeration device according to the second aspect embodiment of the present utility model includes the display box of any one of the above first aspect embodiments of the present utility model, having the advantages of good display effect and not being prone to light leakage.

[0067] And combined with the specific installation structure, it can greatly reduce the assembly cost and production efficiency of the display box, and reduce the overall manufacturing cost of the refrigeration device.

[0068] Of course, in specific implementation, the display box can also be applied to other devices or appliances, such as drying boxes, heating boxes, wine cabinets, etc., which will not be elaborated here.

[0069] Of course, the present utility model is not limited to the above embodiments.
