Description

Technical Field

[0001] This utility model relates to the field of power adapters, specifically an active heat dissipation high-power power adapter. Background Technology

[0002] A power adapter is a power conversion device that converts alternating current (AC) to direct current (DC) and adjusts the voltage and current to meet the needs of electronic devices. It is an indispensable accessory in modern electronic devices and is widely used in various electronic devices such as laptops, mobile phones, tablets, routers, and game consoles.

[0003] During adapter use, traditional passive cooling has low heat dissipation efficiency. When the adapter is running at high power, it cannot quickly remove heat and cannot effectively dissipate heat in time. In order to improve heat dissipation efficiency, a cooling fan is installed on the surface of the adapter, which can force and accelerate the airflow inside the adapter, thereby quickly removing heat.

[0004] However, existing cooling fans are usually fixed to one side of the adapter, and the gap between them and the adapter is fixed. This results in a limited amount of cool air being able to enter the cooling area. The cooling fan may need to run at a higher speed to achieve rapid heat dissipation. However, increasing the speed can easily generate more noise and higher power consumption, thus increasing the negative impact of the cooling fan during use. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, cooling fans are usually fixed to one side of the adapter with a fixed gap size. This results in limited cool air entering the heat dissipation area, and the cooling fan may need to run at a higher speed to achieve rapid heat dissipation. However, increasing the speed can easily generate more noise and higher power consumption, thus increasing the negative impact of the cooling fan during use. This utility model proposes an active cooling high-power power adapter.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an active heat dissipation high-power power adapter, including an adapter body, a heat-conducting rod fixedly installed in the inner cavity of the adapter body, the heat-conducting rod extending to the outside of the adapter body, a heat dissipation plate installed on the top of the adapter body, a cooling fan fixedly installed in the inner cavity of the heat dissipation plate, the number of cooling fans is three, the cooling fans are located on the top of the heat-conducting rod, and an adjustment mechanism is installed on the front side of the adapter body; The adjustment mechanism includes a fixing block, the back of which is fixedly connected to the front of the adapter body. A motor is fixedly connected to the back of the fixing block, and a gear is fixedly connected to the output end of the motor. A gear plate is meshed on the left side of the gear surface, and a connecting plate is fixedly connected to the front of the gear plate. The front of the connecting plate is fixedly connected to the back of the heat sink.

[0007] Preferably, a support plate is fixedly connected to the back side of the connecting plate, and the surface of the support plate is slidably connected to the inner cavity of the fixing block.

[0008] Preferably, the inner cavities of both the toothed plate and the support plate are slidably connected to limit rods, and the surface of the limit rods is fixedly connected to the inner cavity of the fixing block.

[0009] Preferably, an adjustment groove is provided on the back side of the inner cavity of the fixing block, the inner cavity of the adjustment groove is slidably connected to the surface of the connecting plate, and guide grooves are provided on both sides of the inner cavity of the adjustment groove. A guide plate is slidably connected to the inner cavity of the guide groove, and one side of the guide plate is fixedly connected to the surface of the connecting plate.

[0010] Preferably, a noise reduction cover is fixedly connected to the front side of the fixing block, and the inner cavity of the noise reduction cover is fitted onto the surface of the motor.

[0011] Preferably, positioning rods are fixedly connected to the four corners of the top of the adapter body, and the surface of the positioning rods is slidably connected to the inner cavity of the heat sink.

[0012] Preferably, a limiting plate is fixedly connected to the top of the positioning rod, a limiting ring is fixedly connected to the surface of the positioning rod, the bottom of the limiting plate contacts the top of the heat sink, and the top of the limiting ring contacts the bottom of the heat sink.

[0013] The advantages of this utility model are: This invention, by setting up an adjustment mechanism, uses a motor to drive a gear to rotate, which in turn moves a gear plate upwards. This movement of the gear plate then moves a connecting plate, which in turn moves a heat sink. This increases the gap between the heat sink and the top of the adapter body, improving the heat dissipation efficiency of the adapter body. It solves the problems of a fixed gap between the cooling fan and the adapter, which limits the amount of cold air that can enter the heat dissipation area. This also prevents the cooling fan from needing to rotate at a higher speed to dissipate heat quickly, increasing noise and power consumption, and negatively impacting the cooling fan's performance.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses an active heat dissipation high-power power adapter. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 An active heat dissipation high-power power adapter includes an adapter body 1. A heat-conducting rod 6 is fixedly installed in the inner cavity of the adapter body 1 and extends through to the outside of the adapter body 1. A heat dissipation plate 4 is installed on the top of the adapter body 1. A cooling fan 3 is fixedly installed in the inner cavity of the heat dissipation plate 4. There are three cooling fans 3. The cooling fans 3 are located on the top of the heat-conducting rod 6. An adjustment mechanism 2 is installed on the front side of the adapter body 1. The adjustment mechanism 2 includes a fixing block 201. The back side of the fixing block 201 is fixedly connected to the front side of the adapter body 1. A motor 203 is fixedly connected to the back side of the fixing block 201. A gear 210 is fixedly connected to the output end of the motor 203. A toothed plate 204 is meshed on the left side of the surface of the gear 210. A connecting plate 205 is fixedly connected to the front side of the toothed plate 204. The front side of the connecting plate 205 is fixedly connected to the back side of the heat sink 4.

[0019] Reference Figure 4 A support plate 211 is fixedly connected to the back side of the connecting plate 205. The surface of the support plate 211 is slidably connected to the inner cavity of the fixing block 201. The support plate 211 provides support for the movement of the heat sink 4, improves the stability of the heat sink 4 during movement, and prevents the heat sink 4 from getting stuck during movement.

[0020] Reference Figure 4 The inner cavities of the toothed plate 204 and the support plate 211 are slidably connected to limit rods 208. The surface of the limit rods 208 is fixedly connected to the inner cavity of the fixed block 201. By setting the limit rods 208, the movement of the toothed plate 204 and the support plate 211 is limited, so that the toothed plate 204 and the support plate 211 maintain vertical movement and prevent the position of the toothed plate 204 and the support plate 211 from shifting during the movement.

[0021] Reference Figure 4 An adjustment groove 206 is provided on the back side of the inner cavity of the fixing block 201. The inner cavity of the adjustment groove 206 is slidably connected to the surface of the connecting plate 205. Guide grooves 207 are provided on both sides of the inner cavity of the adjustment groove 206. A guide plate 209 is slidably connected to the inner cavity of the guide groove 207. One side of the guide plate 209 is fixedly connected to the surface of the connecting plate 205. By setting the guide groove 207, the guide plate 209 can slide inside the fixing block 201, thereby improving the stability of the connecting plate 205 during the sliding process of the guide plate 209 and facilitating the movement of the connecting plate 205 inside the adjustment groove 206.

[0022] Reference Figure 3 A noise reduction cover 202 is fixedly connected to the front side of the fixing block 201. The inner cavity of the noise reduction cover 202 is fitted onto the surface of the motor 203. By setting the noise reduction cover 202, the surface of the motor 203 is wrapped, which can absorb the noise generated during the operation of the motor 203, thereby reducing the interference to the external environment.

[0023] Reference Figure 1 and Figure 2Positioning rods 7 are fixedly connected to the four corners of the top of the adapter body 1. The surface of the positioning rods 7 is slidably connected to the inner cavity of the heat sink 4. The positioning rods 7 are used to position the heat sink 4, so that the heat sink 4 can move vertically and prevent the position of the heat sink 4 from shifting during the movement.

[0024] Reference Figure 1 and Figure 2 A limiting plate 5 is fixedly connected to the top of the positioning rod 7, and a limiting ring 8 is fixedly connected to the surface of the positioning rod 7. The bottom of the limiting plate 5 contacts the top of the heat sink 4, and the top of the limiting ring 8 contacts the bottom of the heat sink 4. The limiting plate 5 and the limiting ring 8 limit the movement of the heat sink 4, preventing the heat sink 4 from moving too far, causing the heat sink 4 to detach from the surface of the positioning rod 7 or contact the top of the heat conduction rod 6.

[0025] Working Principle: During high-power operation of the adapter body 1, to improve heat dissipation efficiency, the motor 203 is started by an external power source. The motor 203 drives the gear 210 to rotate, which in turn moves the gear plate 204 upwards. This movement of the gear plate 204 then moves the connecting plate 205. During this movement, the supporting plate 211 moves synchronously. The support plate 211 provides stability for the heat sink 4 during movement, preventing jamming. Furthermore, the guide plate 209 guides the movement of the connecting plate 205, improving its stability within the adjustment slot 206. Moving the heat sink 4 increases the gap between it and the top of the adapter body 1, allowing the cooling fan 3 to start via an external power supply. During the operation of the cooling fan 3, more cool air enters the gap, improving the heat exchange efficiency between the heat-conducting rod 6 and the cool air, thus enhancing the heat dissipation efficiency of the adapter body 1. Simultaneously, the heat sink 4 contacts the limiting plate 5 and the limiting ring 8 during its movement. The limiting plate 5 prevents the heat sink 4 from detaching from the surface of the positioning rod 7 during upward movement, thus preventing it from resetting properly. The limiting ring 8 prevents the heat sink 4 from contacting the top of the heat-conducting rod 6 during downward movement, thus preventing the cooling fan 3 and the heat-conducting rod 6 from functioning normally.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
