Description

Technical Field

[0001] This utility model relates to the field of power adapter technology, and in particular to a novel universal power adapter. Background Technology

[0002] With the increasing popularity of electronic devices such as mobile phones, tablets, laptops, and digital cameras, people need to use a variety of power adapters of different specifications in their daily lives and work.

[0003] The poor heat dissipation performance of some power adapters can easily lead to overheating and damage to internal components during prolonged use, affecting their lifespan and safety. In addition, existing power adapters also have shortcomings in safety protection, such as the lack of overvoltage, overcurrent, and short circuit protection. When voltage fluctuations, abnormal currents, or short circuits occur, electronic devices may be damaged, or even fires and other safety accidents may be caused.

[0004] Therefore, this utility model proposes a novel universal power adapter. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and propose a new type of universal power adapter.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel universal power adapter, comprising a housing assembly, the housing assembly being composed of an outer shell, an interface end cover, and a socket bottom cover, and further comprising an adapter circuit board mechanism disposed on the socket bottom cover between the outer shells;

[0007] The heat dissipation assembly consists of a heat dissipation sleeve embedded in the outer casing. A threaded heat-conducting plate is embedded in the heat dissipation sleeve. The threaded heat-conducting plate has a threaded structure. Heat dissipation holes are formed on the heat dissipation sleeve. The heat dissipation holes are distributed in a ring, and the included angle between two adjacent heat dissipation holes is equal.

[0008] Furthermore, dustproof plates are embedded at both ends of the threaded heat-conducting plate inside the heat dissipation sleeve.

[0009] The beneficial effects of adopting the above-mentioned further solution are: dustproof plates are embedded at both ends of the threaded heat-conducting plate inside the heat dissipation sleeve. The dustproof plates adopt a fine mesh structure, which can effectively block dust and debris from entering the heat dissipation sleeve and prevent them from adhering to the threaded heat-conducting plate and affecting the heat conduction efficiency. At the same time, the dustproof plates have good ventilation and do not hinder the flow of air in the heat dissipation sleeve, ensuring that the heat dissipation channel is unobstructed.

[0010] Furthermore, the bottom of the outer casing is provided with snap-fit ​​grooves, which are rectangularly distributed and the spacing between two adjacent snap-fit ​​grooves is equal.

[0011] The beneficial effects of adopting the above-mentioned further solution are as follows: The rectangular snap-fit ​​groove at the bottom of the shell, through a specific size and shape design, can be precisely engaged with the matching buckles, brackets and other fixing components. During installation, the matching fixing components are aligned with the snap-fit ​​groove, and the limiting of the groove and the elastic deformation of the buckle are used to achieve a quick and stable connection. Disassembly can be performed by reversing the operation. The snap-fit ​​grooves are evenly distributed, which ensures the uniformity of force and improves the stability of the connection.

[0012] Furthermore, the bottom cover of the socket is provided with a snap-fit ​​component that snaps into the snap-fit ​​groove.

[0013] The beneficial effects of adopting the above-mentioned further solution are: the snap-fit ​​assembly has an elastic snap-fit ​​block inside. When the bottom cover of the socket is connected to the outer shell, the snap-fit ​​block of the snap-fit ​​assembly is aligned with the snap-fit ​​groove. Under the action of external force, the snap-fit ​​block is compressed and undergoes elastic deformation to enter the snap-fit ​​groove. After entering, the snap-fit ​​block returns to its original shape and tightly engages with the inner wall of the snap-fit ​​groove to achieve a stable snap-fit.

[0014] Furthermore, the snap-fit ​​assembly is composed of a triangular snap-fit ​​plate, which has a triangular structure and whose angle increases sequentially from top to bottom.

[0015] The beneficial effects of adopting the above-mentioned further solution are as follows: the triangular snap-fit ​​plate is in the shape of a triangle that is narrow at the top and wide at the bottom. During installation, the upper part with the smaller angle is aligned with the snap-fit ​​groove first, and it is easily inserted with the guidance of the inclined surface. As it is pressed down, the triangular structure with the increasing angle fits more and more tightly with the inner wall of the snap-fit ​​groove, forming a mechanical lock. Due to its special angle design, when it is pulled up by external force after insertion, the reaction force generated by the inclined surface will make the snap-fit ​​more secure. When disassembling, it is necessary to apply force from a specific direction to break the locking state of the snap-fit ​​angle.

[0016] Furthermore, a spring is embedded in the larger angle of the triangular snap-fit ​​plate. There are two springs in total, and the two springs are symmetrical about the center of the triangular snap-fit ​​plate. The triangular snap-fit ​​plate is snapped together with the snap-fit ​​groove through the springs.

[0017] The beneficial effects of adopting the above-mentioned further solution are as follows: When the triangular snap-fit ​​plate is inserted into the snap-fit ​​groove, the spring piece at the larger angle is squeezed and undergoes elastic deformation, smoothly entering the snap-fit ​​groove. After being inserted into place, the spring piece returns to its original shape, springs outward and tightly locks the inner wall of the snap-fit ​​groove, forming a firm snap-fit. When disassembling, press the spring piece to make it deform and shrink again, releasing the snap-fit ​​with the snap-fit ​​groove, and the parts can be separated. The symmetrically arranged spring pieces ensure that the force is evenly distributed during snap-fit.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1. In this utility model, the heat generated during the operation of the equipment is transferred to the outer shell and then conducted to the heat dissipation sleeve embedded therein. The threaded structure of the threaded heat-conducting plate increases the contact area with heat, efficiently absorbs heat and conducts it quickly along the threaded path. The annularly distributed heat dissipation holes on the heat dissipation sleeve allow air to form convection inside and outside the sleeve. Hot air is discharged from the heat dissipation holes and cold air is replenished, realizing the continuous dissipation of heat and maintaining the stable internal temperature of the equipment.

[0020] 2. In this utility model, the triangular snap-fit ​​plate is in the shape of a triangle that is narrow at the top and wide at the bottom. During installation, the upper part with the smaller angle is aligned with the snap-fit ​​groove first, and it is easily inserted with the help of the inclined surface. As it is pressed down, the triangular structure with the increasing angle fits more and more tightly with the inner wall of the snap-fit ​​groove, forming a mechanical lock. Due to its special angle design, when it is pulled up by external force after insertion, the reaction force generated by the inclined surface will make the snap-fit ​​more secure. When disassembling, it is necessary to apply force from a specific direction to break the locking state of the snap-fit ​​angle. Attached Figure Description

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 protection scope of the present utility model.

[0031] like Figure 1-5 As shown, this utility model provides a technical solution: a novel universal power adapter, including a housing assembly 1, which is composed of an outer shell 11, an interface end cover 12 and a socket bottom cover 13, and further includes an adapter circuit board mechanism 14 disposed on the socket bottom cover 13 between the outer shell 11.

[0032] The heat dissipation assembly 2 consists of a heat dissipation sleeve 22 embedded in the outer casing 11. A threaded heat-conducting plate 23 is embedded in the heat dissipation sleeve 22. The threaded heat-conducting plate 23 has a threaded structure. Heat dissipation holes 221 are opened on the heat dissipation sleeve 22. The heat dissipation holes 221 are distributed in a ring, and the included angle between two adjacent heat dissipation holes 221 is equal. The heat generated by the operation of the equipment is transferred to the outer casing 11 and then conducted to the heat dissipation sleeve 22 embedded therein. The threaded structure of the threaded heat-conducting plate 23 increases the contact area with heat, efficiently absorbs heat and conducts it quickly along the threaded path. The annularly distributed heat dissipation holes 221 on the heat dissipation sleeve 22 allow air to form convection inside and outside the sleeve. Hot air is discharged from the heat dissipation holes 221 and cold air is replenished, realizing the continuous dissipation of heat and maintaining the stable internal temperature of the equipment.

[0033] Dustproof plates 21 are embedded in both ends of the threaded heat-conducting plate 23 inside the heat dissipation sleeve 22. The dustproof plates 21 have a fine mesh structure, which can effectively block dust and debris from entering the heat dissipation sleeve 22 and prevent them from adhering to the threaded heat-conducting plate 23 and affecting the heat conduction efficiency. At the same time, the dustproof plates 21 have good ventilation and do not hinder the flow of air in the heat dissipation sleeve 22, ensuring that the heat dissipation channel is unobstructed.

[0034] The bottom of the outer casing 11 is provided with snap-fit ​​grooves 111. The snap-fit ​​grooves 111 are rectangularly distributed, and the distance between two adjacent snap-fit ​​grooves 111 is equal. The rectangular snap-fit ​​grooves 111 at the bottom of the outer casing 11, through specific size and shape design, can be precisely engaged with matching buckles, brackets and other fixing parts. During installation, the matching fixing parts are aligned with the snap-fit ​​grooves 111. The limiting of the grooves and the elastic deformation of the buckles are used to achieve a quick and stable connection. Disassembly is performed by reversing the operation. The equal spacing of each snap-fit ​​groove 111 ensures the uniformity of force and improves the stability of the connection.

[0035] The bottom cover 13 of the socket is provided with a snap-fit ​​component 3 that snaps into the snap-fit ​​groove 111. The snap-fit ​​component 3 has an elastic snap block inside. When the bottom cover 13 of the socket is connected to the outer shell 11, the snap block of the snap-fit ​​component 3 is aligned with the snap-fit ​​groove 111. Under the action of external force, the snap block is pressed and undergoes elastic deformation to enter the snap-fit ​​groove 111. After entering, the snap block returns to its original shape and tightly engages with the inner wall of the snap-fit ​​groove 111 to achieve a stable snap-fit.

[0036] The snap-fit ​​assembly 3 is composed of a triangular snap-fit ​​plate 31. The triangular snap-fit ​​plate 31 has a triangular structure with the angle increasing from top to bottom. The triangular snap-fit ​​plate 31 is narrow at the top and wide at the bottom. During installation, the upper part with the smaller angle is aligned with the snap-fit ​​groove 111 first, and it is easily inserted with the help of the inclined surface. As it is pressed down, the triangular structure with the increasing angle fits more and more tightly with the inner wall of the snap-fit ​​groove 111, forming a mechanical lock. Due to its special angle design, when it is pulled up by external force after insertion, the reaction force generated by the inclined surface will make the snap-fit ​​more secure. When disassembling, it is necessary to apply force from a specific direction to break the locking state of the snap-fit ​​angle.

[0037] Two spring pieces 32 are embedded in the larger angle of the triangular snap-fit ​​plate 31, and the two spring pieces 32 are symmetrical about the center of the triangular snap-fit ​​plate 31. The triangular snap-fit ​​plate 31 is engaged with the snap-fit ​​groove 111 through the spring pieces 32. When the triangular snap-fit ​​plate 31 is inserted into the snap-fit ​​groove 111, the spring piece 32 at the larger angle is squeezed and undergoes elastic deformation, smoothly entering the snap-fit ​​groove 111. After being inserted into place, the spring piece 32 returns to its original shape, springs outward and tightly locks the inner wall of the snap-fit ​​groove 111, forming a firm engagement. When disassembling, press the spring piece 32 to make it deform and shrink again, releasing the engagement with the snap-fit ​​groove 111, and the parts can be separated. The symmetrical arrangement of the spring pieces 32 ensures that the force is evenly distributed during engagement.
