Description

Technical Field

[0001] This utility model belongs to the technical field of power adapters, specifically relating to a multi-interface charger for electrical equipment. Background Technology

[0002] A multi-interface charger for electrical equipment is a power adapter that integrates multiple charging interfaces, enabling it to power multiple electronic devices simultaneously. It typically features different interfaces and supports mainstream fast charging protocols such as PD and QC, making it compatible with various devices including smartphones, tablets, and laptops. Through intelligent power distribution technology, it automatically identifies device needs and optimizes charging efficiency, preventing overload.

[0003] Currently, in the long-term use of multi-port chargers, poor contact caused by loose interfaces is a particularly prominent issue. Due to frequent plugging and unplugging and mechanical wear, the metal contacts of the interface gradually lose their elasticity, resulting in loose physical contact with the device plug. This poor contact can cause fluctuations in charging current. In addition, loose interfaces accelerate the oxidation process of the metal contacts, further deteriorating conductivity and creating a vicious cycle. This mechanical wear problem often worsens over time, ultimately affecting the normal use of the charger. Utility Model Content

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figures 1-4 This is an embodiment of the present invention, which provides a multi-interface charger for electrical equipment, comprising: The charging mechanism 100 includes a housing 110, a slotted plate 120 fixedly installed on the outside of the housing 110, and a magnetic base 130 fixedly installed on the top of the housing 110. The positioning mechanism 200 includes a positioning plate 210, an insertion port 220 opened on the outside of the positioning plate 210, a bearing seat 230 fixedly installed on the bottom of the positioning plate 210, a reset assembly 240 disposed on the outside of the bearing seat 230, and a shaft 250 fixedly installed on the outside of the reset assembly 240.

[0019] The positioning mechanism 200 is located on the top of the housing 110 above the USB plug 160. Through the magnetic attraction between the magnetic base 130 and the magnet 280, it ensures that other device interfaces can be accurately aligned with the socket 220 when inserted. This top positioning design allows the device interface to be naturally pressed down during insertion, creating ideal mechanical conditions for subsequent positioning and fixing, and effectively avoiding misalignment problems during insertion.

[0020] Specifically, the positioning mechanism 200 also includes a limiting plate 260 fixedly installed on the outside of the shaft 250, an anti-slip plate 270 fixedly installed on the outside of the limiting plate 260, a magnet 280 fixedly installed on the top of the housing 110, and a locking block 290 fixedly installed on the outside of the positioning plate 210.

[0021] When the device interface is inserted into the socket 220, the downward force will push the two limiting plates 260 to unfold and rotate outward. During this process, one side of the anti-slip plate 270 will be in close contact with the surface of the device interface, and quick fixation will be achieved through friction. This dynamic limiting structure can ensure a firm connection without causing significant resistance to the insertion operation.

[0022] Furthermore, the reset assembly 240 includes an annular seat 241 hinged to the outside of the bearing seat 230, a circular block 242 fixedly installed in the inner cavity of the annular seat 241, a rotating shaft 243 hinged to the outside of the circular block 242, and a swing plate 244 fixedly installed in the outer side of the rotating shaft 243. The reset assembly 240 also includes an arc-shaped limiting rod 245 fixedly installed in the outer side of the swing plate 244, a fixing plate 246 fixedly installed in the inner cavity of the annular seat 241, and a reset spring 247 sleeved on the outer side of the arc-shaped limiting rod 245. The end of the reset spring 247 is fixedly connected to the outer side of the fixing plate 246, and the shape of the reset spring 247 is consistent with the shape of the arc-shaped limiting rod 245.

[0023] Among them, the reset spring 247 provides elastic support for the limit plate 260 through the guide of the arc-shaped limit rod 245: on the one hand, it ensures that the limit plate 260 can automatically adjust the clamping force according to the insertion force; on the other hand, it can drive the limit plate 260 to quickly reset when the device is pulled out; after the reset, the limit plate 260 will naturally close and block the socket 220, forming an effective dustproof barrier, which solves the problem of dust accumulation in traditional charging interfaces; The linkage mechanism formed by the rotating shaft 243 and the swing plate 244 converts the rotational motion of the limiting plate 260 into the elastic deformation of the return spring 247. This design not only ensures the smoothness of the opening and closing action of the limiting plate 260, but also amplifies the effect of the return spring 247 through the mechanical structure, making the response of the entire positioning mechanism more sensitive and reliable. The anti-slip plate 270 features a special textured finish, which, while providing frictional fixation, also prevents scratches from forming on the equipment interface. When the limit plate 260 resets, a sealed contact is formed on the inner side of the anti-slip plate 270, further enhancing the dustproof effect. This design balances the dual requirements of reliable fixation and interface protection.

[0024] Preferably, the charging mechanism 100 also includes a slot 140 formed in the inner cavity of the slot plate 120, a connection port 150 formed on the outer side of the housing 110, and a USB plug 160 fixedly installed on the outer side of the housing 110. The end of the shaft 250 is fixedly connected to the outer side of the rotating shaft 243, and the locking block 290 is movably locked in the inner cavity of the slot 140.

[0025] The charging mechanism 100 achieves a detachable connection between the positioning mechanism 200 and the charging mechanism 100 through the precise cooperation between the slot 140 and the block 290. This ensures positioning accuracy during assembly and facilitates later maintenance and replacement. The external layout of the connection port 150 and the USB plug 160 optimizes space utilization, enabling the charger to support multiple charging modes simultaneously. The rigid connection design between the shaft 250 and the rotating shaft 243 efficiently transmits the elastic force of the reset component 240 to the limit plate 260, ensuring consistent force feedback during insertion and removal. Furthermore, the mechanical interlock between the block 290 and the slot 140 prevents structural loosening that may occur during long-term use.

[0026] When the device interface is inserted, it is first guided by the magnetic base 130 to align with the socket 220. The downward pressure pushes the limit plates 260 on both sides to extend outward around the shaft seat 230, and the anti-slip plate 270 is tightly attached to the interface surface to achieve friction fixation. At the same time, the return spring 247 is compressed and deformed to store energy, and transmits elastic support force through the rotating shaft 243 and the swing plate 244. When pulled out, the return spring 247 releases the elastic force to drive the limit plate 260 to automatically return and close, covering the socket 220 to prevent dust. The engagement of the card block 290 and the card slot 140 ensures a stable connection between the positioning mechanism 200 and the charging mechanism 100, while the external USB plug 160 and the connection port 150 support multi-mode charging.

[0027] In summary, precise positioning is achieved through the magnetic cooperation between the magnetic base 130 and the magnet 280, ensuring that the device interface automatically aligns with the socket 220 upon insertion, avoiding misalignment. The dynamic limiting structure of the limiting plate 260 and the anti-slip plate 270 automatically unfolds and clamps the interface upon insertion, providing a stable fixation effect. At the same time, the return spring 247, guided by the arc-shaped limiting rod 245, allows the limiting plate 260 to adaptively adjust the clamping force and quickly return to its closed position upon removal, also providing dust protection. The linkage design of the rotating shaft 243 and the swing plate 244 efficiently converts mechanical motion into elastic deformation, improving response sensitivity. The modular connection of the card block 290 and the card slot 140 ensures assembly accuracy and facilitates maintenance. The overall structure effectively solves the problems of loose interfaces, dust accumulation, and difficult insertion and removal in traditional chargers.
