Power box and display device

Abstract

The application relates to a power box and a display device, which comprise a box main body, a heat dissipation mechanism and a sunshade. The box main body is arranged on a display screen. The heat dissipation mechanism is arranged on a box outer wall of the box main body away from the display screen. The sunshade has a heat insulation part, and the sunshade is connected with the heat dissipation mechanism or the box main body through the heat insulation part. The sunshade is used for shielding sunlight from shining on the heat dissipation mechanism or the heat dissipation mechanism and the box main body. Even if the power box is in a working environment directly irradiated by sunlight, the sunshade can effectively shield the sunlight from shining on the heat dissipation mechanism or the heat dissipation mechanism and the box main body. Meanwhile, the heat insulation part can further isolate the temperature conduction of the sunshade to the heat dissipation mechanism or the box main body, thereby reducing or eliminating the temperature rise of the heat dissipation mechanism and the box main body caused by the sunlight, preventing the heat from being reversely conducted into the box main body, avoiding the temperature rise of the power box from being accelerated, and ensuring the product life and use safety of the power box and the display screen.

Description

Technical Field

[0001] This application relates to the technical field of display devices, and in particular to a power supply box and a display device. Background Technology

[0002] The power supply box is a crucial component of the display screen, its core function being to provide stable power support. The power supply box receives external AC or DC power input and incorporates an AC-DC or DC-DC converter to transform electrical energy into the stable voltage required by the display screen, ensuring its normal operation. Furthermore, some power supply boxes also feature safety mechanisms such as overload protection, short-circuit protection, and overheat protection.

[0003] However, after prolonged operation, the power supply box also becomes a major heat-generating component of the display. To prevent high temperatures from affecting the safe and reliable operation of the power supply box and the display, heat dissipation intervention is necessary. Currently, the heat dissipation methods include active cooling and passive cooling. Active cooling requires a fan on the power supply box, along with air inlets and outlets. The fan drives airflow to remove the heat generated by the power supply box. However, the air inlets and outlets reduce the product's protection level, posing certain safety hazards. Passive cooling uses heat dissipation fins on the outer wall of the power supply box. These fins exchange heat with the ambient air to dissipate the heat generated by the power supply box into the environment. However, when the heat dissipation fins are located on the back of the power supply box and exposed to sunlight for extended periods, they not only fail to conduct the heat generated by the power supply box away but also significantly increase their temperature. This reverses the heat generated by direct sunlight, conducting it back into the power supply box, accelerating the temperature rise and affecting the product lifespan and safety of both the power supply box and the display. Utility Model Content

[0004] Therefore, it is necessary to provide a power supply box and display device to address the problems of traditional technologies reducing product protection levels, poor heat dissipation and cooling effects, and affecting service life and safety.

[0005] A first aspect of this application provides a power supply box comprising:

[0006] The box body is used to be mounted on the display screen;

[0007] A heat dissipation mechanism, wherein the heat dissipation mechanism is mounted on the outer wall of the housing body away from the display screen; and

[0008] A sunshade having a heat insulation part, the sunshade being connected to the heat dissipation mechanism or the box body through the heat insulation part, the sunshade being used to block sunlight from shining on the heat dissipation mechanism or the heat dissipation mechanism and the box body.

[0009] In this power supply box, the main body is used to install onto the display screen. A heat dissipation mechanism is installed on the outer wall of the main body away from the display screen. Through heat exchange with the air in the external environment, the heat generated by the power supply box during operation is conducted into the air, achieving the purpose of heat dissipation and cooling. Furthermore, the sunshade is connected to the heat dissipation mechanism or the main body through its heat insulation part. This allows the power supply box to effectively block sunlight from shining on the heat dissipation mechanism or the main body, even when it is in a working environment with direct sunlight. At the same time, the heat insulation part further prevents the heat from the sunshade from being conducted to the heat dissipation mechanism or the main body, thereby reducing or eliminating the problem of temperature rise of the heat dissipation mechanism and the main body due to sunlight exposure, preventing heat from being conducted back into the main body, avoiding accelerated temperature rise of the power supply box, and ensuring the product life and safety of the power supply box and the display screen.

[0039] The power supply box 10 is an important component of the display screen 20, serving as an external device primarily responsible for powering the display screen 20. Its core function is to provide stable power support to the display screen 20. After prolonged operation, the power supply box 10 also becomes a major heat-generating component of the display screen 20. To prevent high temperatures from affecting the safe and reliable operation of the power supply box 10 and the display screen 20, heat dissipation interventions are necessary for the power supply box 10. Currently, the heat dissipation methods employed include both active and passive cooling. Active cooling requires a fan on the power supply box 10, along with air inlets and outlets. The fan drives airflow to remove the heat generated by the power supply box 10. However, the air inlets and outlets reduce the product's protection level and pose certain safety hazards. Passive cooling involves installing heat dissipation fins 1221 on the outer wall of the power supply box 10. The heat dissipation fins 1221 exchange heat with the ambient air to dissipate the heat generated by the power supply box 10 into the environment. However, when the heat dissipation fins 1221 are located on the back of the power supply box 10 and are exposed to sunlight for a long time, they not only fail to conduct the heat generated by the power supply box 10 away, but also experience a significant temperature rise. This reverses the heat generated by direct sunlight and conducts it back into the power supply box 10, accelerating the temperature rise of the power supply box 10 and affecting the product lifespan and safety of the power supply box 10 and the display screen 20.

[0040] To address the problems existing in the prior art, this application adopts a sunshade 14 on the power supply box 10, with the sunshade 14 connected to the box body 11 or the heat dissipation mechanism 12 via the heat insulation part 13. This effectively blocks direct sunlight from hitting the heat dissipation mechanism 12 or the heat dissipation mechanism 12 and the box body 11, while also preventing heat from the sunshade 14 from being conducted to the heat dissipation mechanism 12 or the box body 11. This prevents the heat dissipation mechanism 12 from heating up due to sunlight, thus avoiding the generation of additional heat that is conducted back into the power supply box 10, protecting the safety and lifespan of the power supply box 10 and the display screen 20.

[0041] See Figure 1 The present application describes a display device 100, which includes a display screen 20 and a power supply box 10. The power supply box 10 is disposed on the back of the display screen 20 and electrically connected to the display screen 20. The power supply box 10 receives external AC or DC power input and has a built-in AC-DC or DC-DC converter to convert electrical energy into a stable voltage required by the display screen 20, ensuring the normal operation of the display screen 20. In addition, some power supply boxes 10 also have safety mechanisms such as overload protection and short circuit protection.

[0042] More specifically, the display screen 20 includes a mounting frame and a screen body. The screen body is mounted on the mounting frame and then fixed in place by the mounting frame. To obtain a larger display area, multiple screen bodies can be installed on the mounting frame simultaneously, and the multiple screen bodies are assembled into one unit using a splicing method.

[0043] The power supply box 10 is also mounted on the mounting bracket, thereby avoiding the need for drilling or slotting on the screen body during assembly, which would affect the structural integrity and performance of the screen body.

[0044] For example, the power supply box 10 and the mounting bracket can be installed using any of the following methods: screw connection, snap-fit ​​connection, magnetic connection, etc. The specific method can be flexibly selected according to actual needs.

[0045] In one embodiment, the display screen 20 has a rectangular structure, and the power supply box 10 has a long strip structure. The power supply box 10 can extend along the length direction of the display screen 20 or along the width direction of the display screen 20.

[0046] Please continue reading. Figure 1 and Figure 2 The figure shows a power supply box 10 according to one embodiment, including a box body 11, a heat dissipation mechanism 12, and a sunshade 14. The box body 11 is the main component of the power supply box 10, serving to house the integrated heat dissipation mechanism 12 and the sunshade 14. It is also easy to understand that the power supply module, controller, and other functional components are also installed inside the box body 11.

[0047] When the power supply box 10 is in use, the box body 11 is used to mount it onto the display screen 20 to achieve the assembly of the power supply box 10 and the display screen 20.

[0048] The heat dissipation mechanism 12 is installed on the outer wall of the box body 11 away from the display screen 20; the sunshade 14 has a heat insulation part 13, and the sunshade 14 is connected to the heat dissipation mechanism 12 or the box body 11 through the heat insulation part 13. The sunshade 14 is used to block sunlight from shining on the heat dissipation mechanism 12 or the heat dissipation mechanism 12 and the box body 11.

[0049] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: In the power supply box 10 of this solution, the box body 11 is used to be installed on the display screen 20. By setting a heat dissipation mechanism 12 on the outer wall of the box body 11 away from the display screen 20, heat exchange occurs through the heat dissipation mechanism 12 contacting the air in the external environment, which can conduct the heat generated by the power supply box 10 during operation to the air, thereby achieving the purpose of heat dissipation and cooling of the power supply box 10; furthermore, by connecting the sunshade 14 to the heat dissipation mechanism 12 or the box body 11 through its heat insulation part 13, the power supply box 10 can achieve the purpose of heat dissipation and cooling. Even in a working environment under direct sunlight, the sunshade 14 can effectively block sunlight from shining on the heat dissipation mechanism 12 or onto the heat dissipation mechanism 12 and the main body 11. At the same time, the heat insulation part 13 can further prevent the heat from the sunshade 14 from being conducted to the heat dissipation mechanism 12 or the main body 11, thereby reducing or eliminating the problem of the heat dissipation mechanism 12 and the main body 11 being overheated due to sunlight, preventing heat from being conducted back into the main body 11, avoiding accelerated temperature rise of the power box 10, and ensuring the product life and safety of the power box 10 and the display screen 20.

[0050] Please continue reading. Figure 2 In one embodiment, the heat dissipation mechanism 12 includes a base 121 and a heat dissipation component 122. The base 121 is disposed on the box body 11, and the heat dissipation component 122 is disposed on the side of the base 121 away from the box body 11. The base 121 is connected to the box body 11 to assemble and fix the heat dissipation mechanism 12 to the box body 11. On this basis, the heat dissipation component 122 is installed on the base 121 and comes into contact with the air in the external environment. This allows the heat generated by the heat-generating components inside the box body 11 to be conducted to the heat dissipation component 122 through the base 121, and then the heat dissipation component 122 exchanges heat with the air to dissipate the heat to the external environment.

[0051] Please continue reading. Figure 2 More specifically, in an optional embodiment, the heat dissipation assembly 122 includes a plurality of heat dissipation teeth 1221, which are arranged side by side at intervals on the base 121. The heat dissipation assembly 122 is formed by a plurality of heat dissipation teeth 1221 arranged side by side at intervals, which can effectively increase the contact area with air and increase the amount of heat conduction between the heat dissipation teeth 1221 and the air per unit time, thereby helping to improve the heat dissipation performance of the power supply box 10.

[0052] For example, the heat dissipation fins 1221 can be in the form of plates, columns, waves, etc., and can be flexibly selected according to actual needs.

[0053] Furthermore, based on any of the above embodiments, the heat dissipation tooth 1221 includes at least two first heat dissipation teeth and at least two second heat dissipation teeth. The height of the first heat dissipation teeth protruding from the base 121 is greater than or less than the height of the second heat dissipation teeth protruding from the base 121, and the first heat dissipation teeth and the second heat dissipation teeth are arranged alternately.

[0054] By alternating the arrangement of first and second heat dissipation fins of different heights, it can effectively prevent the first and second heat dissipation fins from being too close together, which would affect the effective contact between the air and the first and second heat dissipation fins. On the other hand, the first or second heat dissipation fins with a relatively larger height have a larger contact area with the air, which helps to conduct more heat into the air per unit time.

[0055] It should be noted that the alternating arrangement of the first and second heat dissipation teeth can mean that the first and second heat dissipation teeth are arranged alternately, or that one first heat dissipation tooth and two second heat dissipation teeth are arranged alternately, or that two first heat dissipation teeth and two second heat dissipation teeth are arranged alternately, etc.; the specific arrangement can be flexibly selected according to actual needs, and no specific limitation is made here.

[0056] Please continue reading. Figures 3 to 6 Furthermore, in one embodiment, the heat insulation part 13 includes a first isolation strip 131 and a second isolation strip 132, the heat dissipation mechanism 12 includes a first side and a second side spaced apart, and the sunshade 14 includes a third side and a fourth side spaced apart, with the first side facing the third side and the second side facing the fourth side. The first isolation strip 131 connects the first side and the third side, and the second isolation strip 132 connects the second side and the fourth side. Therefore, the first isolation strip 131 can connect and fix the first side and the third side, and the second isolation strip 132 can connect and fix the second side and the third side, so that the sunshade 14 can be assembled onto the heat dissipation mechanism 12. The installation method and structure are simple. The first isolation strip 131 and the second isolation strip 132 provide double-sided support for the sunshade 14, improving the stability of the installation of the sunshade 14, while avoiding direct contact between the sunshade 14 and the heat dissipation mechanism 12. Furthermore, the first isolation strip 131 and the second isolation strip 132 can effectively isolate the high temperature heat generated by the sunshade 14 due to solar radiation, preventing the heat from being conducted from the sunshade 14 to the heat dissipation mechanism 12 or the box body 11.

[0057] Optionally, in order to prevent heat from being conducted from the sunshade 14 to the heat dissipation mechanism 12 or the box body 11, in one embodiment, the sunshade 14 is made entirely of heat-insulating material; or, the first isolation strip 131 and the second isolation strip 132 are made of heat-insulating material. For example, the first isolation strip 131 and the second isolation strip 132 can be, but are not limited to, rubber strips, resin strips, etc.

[0058] Please continue reading. Figure 2 and Figure 6 Furthermore, based on the above embodiment, a first slot 1211 is recessed on the first side, a second slot 1212 is recessed on the second side, a first card body 131 is protruding from the first isolation strip 131, a second card body 132 is protruding from the second isolation strip 132, the first card body 1311 is fitted into the first slot 1211, and the second card body 1321 is fitted into the second slot 1212.

[0059] Therefore, by means of the first card body 1311 and the first card slot 1211 and the second card body 1321 and the second card slot 1212, the first isolation strip 131 and the second isolation strip 132 are assembled and fixed with the heat dissipation mechanism 12. This snap-fit ​​installation method is simple, and the assembly and disassembly operations are convenient and labor-saving, which helps to reduce the processing difficulty and improve production efficiency. Moreover, compared with the installation methods such as threaded connection and adhesive connection, it saves the use of materials such as screws and glue, thus reducing production costs.

[0060] Furthermore, in one embodiment, a third slot 141 is recessed on the third side, a fourth slot 142 is recessed on the fourth side, a third card body 1312 is protruding from the first isolation strip 131, a fourth card body 1322 is protruding from the second isolation strip 132, the third card body 1312 is fitted into the third slot 141, and the fourth card body 1322 is fitted into the fourth slot 142.

[0061] Therefore, by means of the snap-fit ​​between the third clip 1312 and the third clip 141 and the fourth clip 1322 and the fourth clip 142, the first isolation strip 131 and the second isolation strip 132 are assembled and fixed with the sunshade 14. This snap-fit ​​installation method is simple, and the assembly and disassembly operations are convenient and labor-saving, which helps to reduce the processing difficulty and improve production efficiency. Moreover, compared with the installation methods such as threaded connection and adhesive connection, it saves the use of materials such as screws and glue, thus reducing production costs.

[0062] Please continue reading. Figure 4 and Figure 6 Optionally, the first locking body 1311 and the first locking slot 1211, the second locking body 1321 and the second locking slot 1212, the third locking body 1312 and the third locking slot 141, and the fourth locking body 1322 and the fourth locking slot 142 adopt a dovetail joint structure. That is, the cross-section of the first locking slot 1211, the second locking slot 1212, the third locking slot 141 and the fourth locking slot 142 is a regular trapezoid, and the cross-section of the first locking body 1311, the second locking body 1321, the third locking body 1312 and the fourth locking slot 1322 is an inverted trapezoid that matches the size of the regular trapezoid. This kind of tenon and mortise structure has higher connection and fastening force and stability, ensuring that the sunshade 14 is installed reliably and avoiding loosening and falling off under the action of vibration, wind and other forces.

[0063] Please continue reading. Figure 4 Optionally, based on the above embodiments, the sunshade 14, the first isolation strip 131, the heat dissipation mechanism 12, and the second isolation strip 132 cooperate to form a heat dissipation channel 15. More specifically, the heat dissipation channel 15 is a through-hole structure that runs through the power supply box 10. Since the two sides of the sunshade 14 are respectively locked and sealed with the heat dissipation mechanism 12 by dovetail tenons, a chimney effect can be formed inside the heat dissipation channel 15, allowing the hot air close to the heat dissipation mechanism 12 in the heat dissipation channel 15 to be quickly drawn out and discharged, thereby improving the heat dissipation efficiency.

[0064] Based on any of the above embodiments, the sunshade 14 includes a base layer and a reflective layer (not shown in the figure). The base layer is connected to the heat insulation part 13, and the reflective layer is disposed on the side of the base layer away from the heat insulation part 13. The base layer is connected to the heat insulation part 13 to realize the assembly of the sunshade 14 and the heat insulation part 13; at the same time, the base layer is used to support the reflective layer. The reflective layer is located on the outer surface of the sunshade 14, that is, the reflective layer is set to face the sunlight. When sunlight shines on the reflective layer, the reflective layer can reflect more sunlight away, thereby reducing the amount of sunlight that actually shines on the sunshade 14, which helps to control the temperature rise of the sunshade 14 and prevent abnormal temperature rise of the power supply box 10.

[0065] For example, a reflective layer is a thermal insulation material used to reflect sunlight and heat radiation. It can be a thin film made of aluminum foil or metallized film covering the surface of the thermal insulation material.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
