Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power adapters, in particular to a shell for a power adapter. Background Art
[0002] Power adapters are devices that convert power to electricity for small portable electronic devices and electrical appliances. They typically consist of a housing, transformer, inductor, capacitor, PCB, and other components. To ensure safe operation and longevity, power adapters must be sealed and waterproof. Currently, electric vehicles must be charged at designated charging locations within residential communities. Although these locations have rain shelters, strong winds and rain can still cause rain to fall on the electric vehicles and the charging power adapters. Furthermore, electric vehicle power adapters lack waterproofing to effectively dissipate heat.
[0003] The power adapter housing described in Publication No. CN216056779U comprises a waterproof housing, a bottom housing, and an upper housing. The waterproof housing is mounted within the bottom housing, with the outer wall of the waterproof housing cooperating with the inner wall of the bottom housing to form a waterproof rubber groove. The upper housing cover is mounted on the bottom housing and covers the waterproof housing. While this design offers advantages such as good waterproofing, preventing water from entering the adapter housing, and ensuring safety, the prior art still has drawbacks:
[0004] In the prior art, users inject thicker sealant into the upper and lower wire threading grooves, thereby sealing the first lower wire threading hole, the first upper wire threading hole, the second upper wire threading hole, and the second lower wire threading hole, thereby achieving a good waterproof effect. In other places, it is only necessary to inject waterproof glue into the joints between the waterproof shell and the waterproof glue groove, thereby achieving a good sealing effect. However, after the sealant is fully sealed and waterproof, it will affect the effective heat dissipation of the electrical components inside the shell. Utility Model Content
[0005] The technical problem to be solved by the utility model is to overcome the above-mentioned defects and provide a housing for a power adapter.
[0006] In order to solve the above technical problems, the present invention provides a technical solution: a housing for a power adapter, comprising:
[0007] A lower shell, wherein an upper shell is provided on the upper end of the lower shell;
[0008] A heat dissipation mechanism is provided on the upper housing, comprising an extension seat provided on both sides of the lower end of the upper housing, a plurality of evenly distributed ventilation slots 1 are provided on both sides of the upper housing, and a plurality of evenly distributed ventilation slots 2 are provided on the lower end of the extension seat;

[0010] As an improvement, a wire hole is opened in the middle of the front and rear ends of the lower shell.
[0011] As an improvement, supporting feet are fixedly connected to the front and rear sides of the lower end of the lower shell.
[0012] As an improvement, the lower edge of the extension seat extends downward to be lower than the height of the upper shell, and the second lower end of the groove is flush with the lower end of the upper shell.
[0013] As an improvement, the upper ends of both sides of the lower shell are fixedly connected with fixed clamping plates used in conjunction with the extension seat.
[0014] As an improvement, a number of evenly distributed heat dissipation fins are provided on the front and rear sides of the lower shell and the upper shell.
[0015] The advantages of the present invention over the prior art are that when used, the present invention dissipates heat inside the upper shell and the lower shell through the second ventilation slot and the pair of ventilation slots, and the second ventilation slot is located at the lower end of the upper shell, and the lower end edge of the extension seat extends downward below the height of the upper shell. When the shell is used outdoors, after the power adapter is placed at a certain height, rainwater is not easy to enter the upper shell and the lower shell through the upper end or the side of the upper shell, which can ensure effective ventilation and heat dissipation and effectively prevent rainwater. Therefore, the overall structure of the power adapter shell is simple, and the heat dissipation and rainproof functions are better. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will be described in further detail below with reference to the accompanying drawings.
[0027] A housing for a power adapter comprises a lower housing 1. An upper housing 2 is provided on the upper end of the lower housing 1. The upper housing 2 is fixedly connected to the lower housing 1 to form a main body of the adapter housing.
[0028] The top of the base 3 is provided with a heat dissipation mechanism 3, which includes an extension seat 31 provided on both sides of the lower end of the upper shell, and the lower end edge of the extension seat 31 extends downwardly below the height of the upper shell 2. The upper ends of the two sides of the lower shell 1 are fixedly connected with a fixing card 7 used in conjunction with the extension seat 31, which is convenient for connecting the lower end extension part of the extension seat 31 with the lower shell 1. A number of evenly distributed ventilation slots 32 are provided on both sides of the upper shell 2, and a number of evenly distributed ventilation slots 2 33 are provided on the lower end of the extension seat 31. A number of evenly distributed heat dissipation fins 8 are provided on the front and rear sides of the lower shell 1 and the upper shell 2. Therefore, when in use, the upper shell 2 and the lower shell are cooled by the ventilation slots 2 33 and the ventilation slots 1 32. The heat dissipation fins 8 assist in heat dissipation, and the ventilation slots 2 33 are located at the lower end of the upper shell 2. When used outdoors, after the adapter is placed at a certain height, rainwater is not easy to enter the upper shell 2 and the lower shell 1 through the upper end or the side of the upper shell 2, which can ensure effective ventilation and heat dissipation and effectively release rainwater.
[0029] A filtering mechanism 4 is provided on the upper shell 2, and a groove 41 is provided in the middle of both sides of the inner side of the upper shell 2. A filter screen 42 used in conjunction with the ventilation slot 32 is fixedly connected inside the groove 41. A groove 2 43 is provided at the lower end of the inner side of the extension seat 31. The lower end of the groove 2 43 is flush with the lower end of the upper shell 2, and the lower end edge of the extension seat 31 is lower than the height of the groove 2 43, so as to better protect it. A filter screen 2 44 is fixedly connected inside the groove 2 43. The filter screen 1 42 and the filter screen 2 44 can effectively prevent dust from entering the upper shell 2 and the lower shell 1.
[0030] A wire hole 5 is provided in the middle of the front and rear ends of the lower shell 1 , and supporting feet 6 are fixedly connected to the front and rear sides of the lower end of the lower shell 1 .
[0031] When the utility model is implemented, Figure 1-9 As shown, when in use, the upper shell 2 and the lower shell 1 are fixedly connected to form the main body of the adapter shell, and extension seats 31 are provided on both sides of the lower end of the upper shell. The lower end edge of the extension seat 31 extends downward below the height of the upper shell 2, and the front and rear ends of the upper ends of both sides of the lower shell 1 are fixedly connected with fixed clips 7 used in conjunction with the extension seat 31, which facilitates the connection between the lower end extension part of the extension seat 31 and the lower shell 1.
[0032] When in use, the upper shell 2 and the lower shell are cooled by the ventilation slots 2 33 and the ventilation slots 1 32, and the heat dissipation fins 8 assist in heat dissipation. The ventilation slots 2 33 are located at the lower end of the upper shell 2, and the lower end edge of the extension seat 31 extends downward to be lower than the height of the upper shell 2. For example, when the shell is used for an electric vehicle power adapter and is used in an outdoor area with a charging pile, after the adapter is placed at a certain height, rainwater will not easily enter the upper shell 2 and the lower shell 1 through the upper end or the side of the upper shell 2, which can ensure effective ventilation and heat dissipation and effectively prevent rainwater. The filter screen 1 42 and the filter screen 2 44 can effectively prevent dust from the inside of the upper shell 2 and the lower shell 1. The overall structure of the power adapter shell is simple, and the heat dissipation and rainproof functions are better.
