Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power adapters, in particular to a power adapter with good heat dissipation. Background Art
[0002] A power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. Its main function is to convert alternating current into direct current and adjust the voltage and current to a specific range to meet the power required for the normal operation of electronic devices.
[0003] During the operation of the power adapter, certain heat will be generated. This is mainly because the internal electronic components will generate energy loss when current passes through, and a part of the energy will be converted into heat energy. If the power adapter works in a high-temperature environment for a long time or has poor heat dissipation, then these heats will continuously accumulate, resulting in the continuous increase of the temperature of the power adapter, thereby reducing the service life of the power adapter. However, the heat dissipation effect of the current power adapters on the market is generally not good, which is not conducive to the use of the power adapter. Therefore, there is an urgent need for a power adapter with good heat dissipation effect. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a power adapter with good heat dissipation.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A power adapter with good heat dissipation includes a power adapter body. Silicone bases are fixedly arranged at the corners of the bottom of the power adapter body. Two support plate cavities are oppositely opened at both ends of the bottom of the power adapter body, and support plates are rotatably arranged in the support plate cavities; a plurality of spring cavities are opened at the bottom of the power adapter body, and the spring cavities are all located outside the support plate cavities. Springs are installed in the spring cavities, and movable plates are installed below each side of the spring cavities.
[0007] In addition, the preferred structure is that two movable plates are provided and are respectively located on both sides of the bottom of the power adapter body, and both ends of the movable plates are connected to the springs.
[0008] In addition, the preferred structure is that rotary hinges are arranged at the ends of the support plate cavities far away from the movable plates, and the support plates rotate through the rotary hinges.
[0009] In addition, the preferred structure is that guide post cavities are opened outside the spring cavities at the bottom of the power adapter body, and guide posts are movably arranged in the guide post cavities.
[0010] In addition, a preferred structure is that an anti - detachment block is fixedly arranged at the top of the guiding column, and the bottom of the guiding column is connected to the movable plate.
[0011] In addition, a preferred structure is that a clamping groove is adaptively formed at the top of the movable plate corresponding to the end of the supporting plate. Anti - slip pads are laid on both the end of the supporting plate and inside the clamping groove, and a soft silicone block is arranged above the clamping groove on the movable plate.
[0012] The beneficial effects of the present utility model are as follows: Through the arrangement of the movable plate and the supporting plate, the power adapter body can be propped up, thereby increasing the height of the power adapter body and the distance between the power adapter body and the desktop, facilitating the transfer of heat inside the power adapter body to the air, and thus improving the heat dissipation efficiency of the power adapter body.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0021] Reference Figures 1-6 , a power adapter with good heat dissipation, including a power adapter body 1. Silicone bases 11 are fixedly arranged at the corners of the bottom of the power adapter body 1. Two support plate cavities 32 are oppositely opened at both ends of the bottom of the power adapter body 1, and support plates 3 are rotatably arranged in the support plate cavities 32. A plurality of spring cavities 41 are opened at the bottom of the power adapter body 1, and the spring cavities 41 are all located outside the support plate cavities 32. Springs 4 are installed in the spring cavities 41, and movable plates 2 are installed below each side of the spring cavities 41.
[0022] It should be noted that the specific structure and working mode of the power adapter body 1 are all prior arts already disclosed in the current market. They are all common general knowledge well-known to those skilled in the art and do not belong to the main technical problems to be solved in this technical solution. Therefore, they will not be elaborated in this utility model. And the support plate cavities 32, spring cavities 41 and guide post cavities 51 in this device are all opened on the housing of the power adapter body 1, and they will not affect the internal structure of the power adapter body 1.
[0023] Among them, two movable plates 2 are provided and are respectively located on both sides of the bottom of the power adapter body 1, and both ends of the movable plates 2 are connected to the springs 4. The springs 4 are normally located in the spring cavities 41. Through the setting of the springs 4, the movable plates 2 can be tightened when not in use, so that they will not shake outside.
[0024] Among them, rotary hinges 31 are arranged at one ends of the support plate cavities 32 far from the movable plates 2, and the support plates 3 are rotated through the rotary hinges 31. Through the setting of the support hinges 31, the support plates 3 can be driven to rotate.
[0025] Among them, guide post cavities 51 are opened at the bottom of the power adapter body 1 outside the spring cavities 41, and guide posts 5 are movably arranged in the guide post cavities 51. Anti-dropping blocks are fixedly arranged at the tops of the guide posts 5, and the bottoms of the guide posts 5 are all connected to the movable plates 2. Among them, anti-dropping blocks with a diameter larger than that of the guide posts 5 are arranged at the tops of the guide posts 5, and the diameter of the bottom of the guide post cavity is smaller than that of the anti-dropping blocks, so that the guide posts 5 can be prevented from falling off from the guide post cavities 51. Through the setting of the guide posts 5, the movable plates 2 can be guided.
[0026] Among them, clamping grooves 6 are adaptively opened at the tops of the movable plates 2 corresponding to the ends of the support plates 3. Anti-slip pads are laid on the ends of the support plates 3 and in the clamping grooves 6, and soft silicone blocks 61 are arranged above the clamping grooves 6 on the movable plates 2. Through the setting of the anti-slip pads, the ends of the support plates 3 can be prevented from falling off from the clamping grooves 6. And through the setting of the soft silicone blocks 61, the ends of the support plates 3 can be further limited.
[0027] In this embodiment, when the user needs to dissipate heat from the power adapter body 1, the user only needs to pull down the movable plates 2 on both sides of the bottom of the power adapter body 1. When the movable plates 2 are pulled down, the support plates 3 will rotate downward due to their own gravity because there is no support from the movable plates 2. Subsequently, the user only needs to insert the ends of the support plates 3 into the card slots 6 on the movable plates 2, so as to increase the height of the power adapter body 1 through the movable plates 2 and the support plates 3. Thus, the bottom of the power adapter body 1 does not contact the desktop, thereby improving the heat dissipation efficiency of the power adapter body 1.
[0028] Further, when the user pushes the movable plate 2 into the inside of the card slot 6, due to the arrangement of the movable plate 2 and the anti-slip pads in the card slot 6, the movable plate 2 can be prevented from loosening. And through the arrangement of the soft silicone block 61, the end of the movable plate 2 can be further clamped, thereby further preventing it from loosening.
[0029] Further, the height of the movable plate 2 is the same as the height of the silicone base 11. When the movable plate 2 is not in use, through the arrangement of the spring 4, the movable plate 2 can be tightened at the bottom of the power adapter body 1, and the support plate 3 can be clamped and limited by the movable plate 2. Thus, it will not affect the normal use of the power adapter body 1 due to the movable plate 2 and the support plate 3.
[0030] In the present utility model, through the arrangement of the movable plate 2 and the support plate 3, the power adapter body 1 can be propped up, thereby increasing the height of the power adapter body 1 and the distance between the power adapter body 1 and the desktop, so as to facilitate the transfer of the heat in the power adapter body 1 to the air, thereby improving the heat dissipation efficiency of the power adapter body 1.
[0031] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
