A gallium nitride multi-port charger

Abstract

This utility model discloses a gallium nitride multi-port charger, including a charger body protective cover, a locking component, and an operating part. The charger body integrates a power plug and a charging interface. This utility model provides dual protection through the protective cover and a first sealing structure: the protective cover physically shields the charging interface via a rotatable connection structure, while the first sealing structure adheres to the side surface of the charger body along the edge of the protective cover, effectively preventing dust and water stains from entering through gaps. Even in damp bathrooms or dusty outdoor camping environments, it prevents oxidation and short circuits of the charging interface's metal contacts, significantly extending the interface's lifespan and reducing the risk of charging failures due to protection failure. Simultaneously, the second sealing structure is positioned around the outer periphery of the power plug, completely filling the space between the charger and the socket when the plug is inserted, preventing contact contamination caused by dust accumulation or liquid splashes.

Description

Technical Field

[0001] This utility model relates to the field of charger technology, and more specifically, to a gallium nitride multi-port charger. Background Technology

[0002] With the widespread adoption of gallium nitride (GaN) technology in the power supply field, GaN multi-port chargers have become the mainstream charging devices for home, office, and outdoor portable scenarios due to their high power density, miniaturization, and compatibility with multiple devices. Existing GaN multi-port chargers typically integrate multiple different interfaces. As a key component for power output, the interface is frequently plugged and unplugged from external devices and is directly exposed to the external environment. Therefore, there is a clear requirement for waterproofing and dustproofing. Especially in scenarios such as outdoor camping and water stains on desktops, the interface's protection capability directly determines the charger's safety and lifespan.

[0003] Existing gallium nitride multi-port chargers generally lack protective structures. If splashed with water (such as when a cup of water is spilled on a table), moisture can easily seep into the charger through gaps and come into contact with chips and other components on the PCB board, posing a risk of open circuit.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0017] According to an embodiment of the present invention, a gallium nitride multi-port charger is provided.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-3 As shown, a gallium nitride multi-port charger according to an embodiment of the present utility model includes a charger body 1, a protective cover 4, a locking component 5, and an operation part 6. The charger body 1 integrates a power plug 2 and a charging interface 3. The protective cover 4 is mounted on the side surface of the charger body 1 via a rotatable connection structure, and the coverage area of ​​the protective cover 4 is set to correspond to the position of the charging interface 3. The locking component 5 is located between the protective cover 4 and the charger body 1; The operating part 6 protrudes from the outer side of the protective cover 4.

[0019] In one embodiment, to improve the waterproof and dustproof effect of the protective cover 4 on the charging interface 3, and to prevent external dust and moisture from entering the charging interface 3 through the gap between the protective cover 4 and the charger body 1, thereby affecting the service life and charging safety of the charging interface 3.

[0020] Specifically, the inner side of the protective cover 4 is provided with a first sealing structure 7, and the first sealing structure 7 is provided along the edge contour of the protective cover 4.

[0021] In one embodiment, when the protective cover 4 is in a closed state, the first sealing structure 7 can fit tightly against the side surface of the charger body 1 to form a sealing barrier, effectively preventing dust and moisture from entering the charging interface 3, and ensuring that the charging interface 3 can still work stably in complex environments.

[0022] Specifically, the side surface of the charger body 1 is provided with a second sealing structure 8, and the coverage area of ​​the second sealing structure 8 corresponds to the outer periphery of the power supply plug 2.

[0023] In one embodiment, the second sealing structure 8 can completely enclose the outer periphery of the power plug 2, preventing external dust and moisture from contacting the metal contacts of the power plug 2, ensuring the cleanliness and electrical performance of the power plug 2, and extending the service life of the power plug 2.

[0024] Specifically, the side surface of the charger body 1 is provided with an anti-slip structure, which consists of multiple protrusions 9 protruding from the outer surface of the charger body 1.

[0025] In one embodiment, these bumps 9 can increase the friction between the user's hand and the charger body 1, allowing for a more stable grip whether the user is plugging or unplugging the charger with one hand or moving the charger with both hands, effectively preventing slippage.

[0026] Specifically, a recessed structure 10 is provided on the side surface of the charger body 1, and the recessed structure 10 extends along the length direction of the charger body 1.

[0027] In one embodiment, the charging cable can pass through the recessed structure 10.

[0028] Specifically, the first sealing structure 7 and the second sealing structure 8 are elastic sealing rings, and the material of the elastic sealing rings is silicone.

[0029] In one embodiment, the silicone material has excellent elasticity, which can generate an appropriate amount of compression when it is attached to the charger body 1 or the protective cover 4 to ensure a sealing effect; at the same time, silicone is resistant to high and low temperatures and aging, and can adapt to temperature changes during charger operation and different usage environments. Moreover, silicone material is environmentally friendly and non-toxic, meets relevant product standards, and will not have an adverse impact on user health and the environment.

[0030] Specifically, the rotatable connection structure is a rotating shaft assembly, and the locking component 5 is a snap-fit ​​assembly.

[0031] In one embodiment, the rotating shaft assembly has a simple structure and rotates smoothly, allowing the protective cover 4 to rotate flexibly within a certain angle range, meeting the user's operational needs for opening and closing the protective cover 4; the buckle assembly has good locking performance, and when the protective cover 4 is closed, the buckle assembly can quickly fix the protective cover 4 to the charger body 1, and the unlocking operation is simple. The user only needs to apply a certain external force through the operating part 6 to open the protective cover 4, taking into account both locking reliability and operation convenience.

[0032] Working principle: During the use of the charger, rotate the protective cover 4 to the closed state, and the buckle assembly will automatically lock. At this time, the first sealing structure 7 on the inner side of the protective cover 4 will fit tightly with the side surface of the charger to form an annular sealing barrier. This barrier can prevent external dust particles from entering the interface and prevent liquid from seeping in through the gap between the protective cover 4 and the body, thus avoiding oxidation and short circuit of the interface metal contacts. At the same time, the second sealing structure 8 on the side surface of the charger body 1 will naturally fill the outer periphery of the plug. The elasticity of the silicone makes it fit tightly with the plug shell, completely covering the metal contact area and isolating dust accumulation and liquid splashes.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
