Description

Technical Field

[0001] The utility model relates to the technical field of power adapters, specifically to a moisture-proof and drop-proof power adapter device. Background Art

[0002] A power adapter is a power conversion device for small portable electronic devices and electronic appliances. It is generally composed of components such as a casing, a transformer, an inductor, a capacitor, a control IC, a PCB board, etc. Its working principle is to convert AC input into DC output. It is commonly found in small electronic products such as mobile phones, LCD monitors, and laptops.

[0003] An existing patent (publication number: CN 214228106 U) discloses a moisture-proof and drop-proof power adapter device, which prevents the power cord from being tangled and inconvenient to untie by means of a storage buckle, so that the power cord can be neatly stored and convenient to carry. The spring and baffle plate can buffer the impact force of the power adapter when it falls, and the spring plays a shock-absorbing role on the power adapter through deformation, thereby improving the drop resistance of the power adapter. The second partition and the third partition are adjusted in height by means of a first gear, so that the power adapter body is kept away from the desktop, achieving a moisture-proof and waterproof effect, thereby improving the service life.

[0004] However, the above technical solution still has certain defects. During the use of the moisture-proof and drop-proof power adapter by the user, as the use time increases, there will be certain wear between the USB plug and the USB interface on the adapter. When the USB plug is inserted into the USB interface, the wear will cause the connection between the two to be loose, causing the USB plug to become loose. Even under the action of a slight external force, the USB plug will fall off from the USB interface, causing the device to be disconnected from the USB interface, reducing the user's experience. Therefore, a moisture-proof and drop-proof power adapter device is proposed. Utility Model Content

[0032] The moisture-proof component 300 includes a heat insulating plate 310 fixedly connected to the inner wall of the shell 210 , a heat conducting plate 320 fixedly connected to the inner side of the heat insulating plate 310 away from the shell 210 , and an expansion sealing ring 330 fixedly connected to one end of the heat conducting plate 320 away from the adapter body 110 .

[0033] When in use, the user can insert the USB plug 130 into the USB interface 120 to connect and use the adapter body 110. The multiple rubber rings 150 wrapped around the outer wall of the adapter body 110 can effectively alleviate the impact force and avoid damage to the device when the device falls and collides with the ground. Before inserting the USB plug 130, the user first pulls the handle 240 to make the handle 240 drive the pull plate 230 to move, the movement of the pull plate 230 drives the shaft 220 to rotate, the rotation of the shaft 220 drives the first belt 250 to rotate, the rotation of the first belt 250 drives the first linkage shaft 260 to rotate, and the rotation of the first linkage shaft 260 drives the first gear 270 to rotate.

When the plug block 290 enters the interior of the housing 210, the user can insert the USB plug 130 into the USB interface 120. After the USB plug 130 is inserted, the user pushes the handle 240 inwards to reverse the above operation steps, so as to allow the plug block 290 to enter the fixing groove 140, thereby fixing the USB plug 130 and preventing the USB plug 130 from being loosened due to wear between the USB plug 130 and the device after a long period of use. The USB plug 130 is prevented from falling off from the USB interface 120 under the action of a slight external force, causing the device and the USB interface 120 to be disconnected, thereby reducing the user's experience. When the device is in use, a certain amount of heat is generated between the USB plug 130 and the device due to current exchange. The heat is transferred to the expansion sealing ring 330 through the heat conducting plate 320, causing the expansion sealing ring 330 to expand due to the heat and squeeze the USB plug 130, thereby achieving a moisture-proof effect on the device and preventing water vapor in the air from entering the device, causing short circuit or damage to internal components of the device, thereby reducing the service life of the device.

[0038] Please refer to Figure 3 One end of the expansion sealing ring 330 away from the heat conducting plate 320 is fixedly connected to the inner wall of the shell 210 .

[0039] Due to the current exchange between the USB plug 130 and the device, a certain amount of heat will be generated, and the heat will be transferred to the expansion sealing ring 330 through the heat conducting plate 320, so that the expansion sealing ring 330 expands due to the heat and squeezes the USB plug 130, thereby achieving a moisture-proof effect on the device, preventing water vapor in the air from entering the device, causing short circuit or damage to the internal components of the device, and reducing the service life of the device.

[0040] When in use, the user can insert the USB plug 130 into the USB interface 120 to connect and use the adapter body 110. The multiple rubber rings 150 wrapped around the outer wall of the adapter body 110 can effectively alleviate the impact force and avoid damage to the device when the device falls and collides with the ground. Before inserting the USB plug 130, the user first pulls the handle 240 to make the handle 240 drive the pull plate 230 to move, the movement of the pull plate 230 drives the shaft 220 to rotate, the rotation of the shaft 220 drives the first belt 250 to rotate, the rotation of the first belt 250 drives the first linkage shaft 260 to rotate, the rotation of the first linkage shaft 260 drives the first gear 270 to rotate, and the first gear 2 The rotation of the first rack 280 drives the L-shaped connecting plate 291 to move horizontally, and the L-shaped connecting plate 291 drives the plug-in block 290 to move horizontally toward the inside of the housing 210. When the rotating shaft 220 rotates, the second belt 2910 also rotates at the same time. The rotation of the second belt 2910 drives the second linkage shaft 2920 to rotate. The rotation of the second linkage shaft 2920 drives the second gear 2930 to rotate. The rotation of the second gear 2930 drives the second rack 2940 to move horizontally. The second rack 2940 drives the plug-in block 290 to move horizontally toward the inside of the housing 210. The first rack 280 and the second rack 2940 are respectively located on both sides of the plug-in block 290, which can effectively alleviate the plug-in block. In the process of moving, the plug block 290 is stuck, so that the movement of the plug block 290 is smoother. When the plug block 290 enters the interior of the housing 210, the user can insert the USB plug 130 into the USB interface 120. When the USB plug 130 is inserted, the user pushes the handle 240 inward to reverse the above operation steps, so as to allow the plug block 290 to enter the fixing groove 140, thereby fixing the USB plug 130 and preventing the device from being used for a long time due to wear and tear between the USB plug 130 and the device, resulting in a loose connection between the two and causing the USB plug to become loose, and preventing the USB plug 130 from being loosened due to slight external force. In this case, the USB plug 130 will fall off from the USB interface 120, causing the device to be disconnected from the USB interface 120, thereby reducing the user experience. When the device is in use, a certain amount of heat will be generated due to the current exchange between the USB plug 130 and the device. The heat will be transferred to the expansion sealing ring 330 through the heat conducting plate 320, causing the expansion sealing ring 330 to expand due to the heat and squeeze the USB plug 130, thereby achieving a moisture-proof effect on the device and preventing water vapor in the air from entering the device, causing short circuit or damage to the internal components of the device and reducing the service life of the device.
