Description

Technical Field

[0001] The utility model relates to the technical field of AC charging guns for new energy vehicles, in particular to a waterproof button assembly for a charging gun. Background Art

[0002] With the rapid development and increasing penetration of the new energy vehicle industry, market demand for charging guns, a key component of new energy vehicles, is also increasing. At the same time, as consumers' demands for product quality and safety increase, charging gun waterproof button assemblies with superior waterproof performance will become increasingly popular in the market. The charging gun waterproof button assembly is a critical component of the charging gun, providing waterproof protection during charging, ensuring normal and safe operation in humid or rainy environments.

[0003] Currently, waterproof button assemblies on the market often use rubber encapsulation or hot melting to fix the seals. These methods are often costly, have low mass production capabilities, and have unstable quality. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a charging gun waterproof button assembly, which is conducive to the sealing and installation of the waterproof button.

[0005] The utility model adopts the following technical solutions to achieve the purpose of the utility model:

[0006] A waterproof charging gun button assembly is characterized by comprising: a charging gun housing, which is hollow and provided with a button sealing gasket groove and a button thread ring groove, wherein the button sealing gasket groove is connected to the button thread ring groove; a microswitch mounted on a PCB board, wherein the PCB board is disposed within the hollow shell of the charging gun housing and is fixedly connected to the charging gun housing; a button sealing gasket that matches the button sealing gasket groove and the microswitch; a button cover that matches the microswitch; and a button pressure ring, wherein the upper portion of the button cover and the button sealing gasket is disposed within the button pressure ring, wherein the button pressure ring is disposed within the button thread ring groove. The button sealing gasket provides a certain elastic force to ensure that the button cover rebounds smoothly after being pressed and released. The button pressure ring prevents the button cover from falling out of the button assembly and also presses down on the button sealing gasket to prevent water from entering through the button sealing gasket, thereby more effectively blocking external moisture and humidity from entering the device.

[0007] As a further limitation of the present technical solution, the center of the button sealing gasket protrudes outward to form a hollow cone, the hollow cone matches the button sealing gasket groove, and the micro switch matches the hollow cone. By providing the hollow cone, the positioning of the micro switch is achieved.

[0008] As a further limitation of this technical solution, the button pressing ring is provided with a three-step stepped groove, the button cover is a convex ring, the button cover is disposed within the two upper grooves of the three-step stepped groove, and the upper portion of the button sealing gasket is disposed within the lower groove of the three-step stepped groove. The provision of the three-step stepped groove facilitates positioning and installation of the button cover and button sealing gasket.

[0009] As a further limitation of this technical solution, the center of the button cover is convex downward to form a contact cylinder, and the contact cylinder matches the micro switch. By providing the contact cylinder, it is convenient to press the button seal and the micro switch.

[0010] As a further limitation of this technical solution, the button gasket is provided with an annular groove on its edge, which mates with a metal gasket, which in turn mates with the lower groove of the three-stepped groove. The metal gasket protects the button gasket from cracking. During assembly, the button pressure ring must be screwed into the button threaded groove. During this rotation, the metal gasket blocks the button gasket from rotating, thereby preventing the gasket from cracking due to excessive rotation.

[0011] As a further limitation of the present technical solution, the button pressing ring is threadedly connected to the button thread ring, and the button thread ring matches the button thread ring groove.

[0012] As a further limitation of the present technical solution, the upper and lower ends of the button thread ring protrude outward to form a group of evenly distributed anti-slip protrusions.

[0013] Compared with related technologies, the waterproof button assembly of a charging gun provided by the present invention has the following beneficial effects:

[0014] (1) This device uses molding and spiral assembly to fix the button cover and seal to achieve waterproof function and IP67 waterproof effect. It can be easily assembled without the help of jigs and has low cost. It can be completely assembled in the post-process. It is reliable and easy to assemble.

[0015] (2) The button pressing ring of the device prevents the button cover from falling out of the button assembly. Another function is to press the button sealing gasket to prevent water from entering through the button sealing gasket, which can more effectively block external water vapor and moisture from entering the interior of the device;

[0016] (3) This device transmits the force applied by pressing the button cover to the button gasket, and finally to the micro switch, thereby realizing the switching of the entire PCB circuit. The button gasket can provide a certain elastic force to ensure that the button cover can rebound smoothly after being pressed and released. BRIEF DESCRIPTION OF THE DRAWINGS
