Description

Technical Field

[0001] This utility model relates to the field of charger structure, and in particular to a charger that integrates the button function of the charger with the charger indicator light. Background Technology

[0002] In the field of electric bicycle chargers, the human-machine interface typically includes two main functional modules: operation buttons (such as mode switching buttons and reset buttons) and status indicator lights (such as charging status lights and fault alarm lights). Traditional designs generally adopt a separate structure, which requires multiple holes to be made on the charger's casing. Furthermore, the buttons and indicator lights need to be installed in separate steps during assembly, making the process cumbersome and the internal wiring complex. Therefore, a simpler solution is needed to integrate the buttons and indicator lights. Utility Model Content

[0003] To address this problem, this utility model proposes a charger LED indicator mounting structure, comprising a housing, a light guide post, and an LED light board. The housing includes an outer side and an inner side, with a light guide hole on the housing. Multiple fixing posts extend inward from the inner side of the housing, and fixing grooves are formed on the fixing posts. The LED light board is equipped with LED beads and a micro switch. The light guide post is inserted into the light guide hole of the housing from the inner side, so that the top of the light guide post is exposed on the outer side of the housing. A protrusion is provided at the bottom of the light guide post, which corresponds to and contacts the micro switch of the LED light board. The edge of the LED light board is engaged with the fixing groove.

[0004] Furthermore, the light guide post is loosely fitted with the light guide hole in the housing.

[0005] Furthermore, the LED beads are positioned below the bottom of the light guide column.

[0006] Furthermore, an installation sleeve is provided inside the light guide hole, and the light guide post is installed inside the installation sleeve.

[0007] Furthermore, a limiting shoulder is provided on the side of the light guide post, and the limiting shoulder is restricted by the bottom of the mounting sleeve.

[0008] Furthermore, the opening directions of the fixing slots on each fixing column are different.

[0009] Compared with the existing technology, the advantages of this utility model are: the light guide column simultaneously undertakes the functions of light transmission and pressure transmission, and the operation feedback and status display are integrated by a single hole, which can simplify the assembly process and improve the structural reliability. At the same time, no additional locking structure is required when installing the LED light board; the LED light board can be quickly installed by locking it with the fixing slot.

[0025] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please refer to Figures 1-3 This utility model proposes a charger LED indicator mounting structure, including a housing 1, a light guide post 2, and an LED light board 3. The housing 1 includes an outer side and an inner side. A light guide hole 11 is provided on the housing 1. Multiple fixing posts 12 extend inward from the inner side of the housing 1. Fixing grooves 13 are provided on the fixing posts 12. The fixing grooves 13 are used to engage the periphery of the LED light board 3, so that the LED light board 3 can be fixed in a fixed position on the inner side of the housing 1.

[0029] The LED light panel 3 is provided with LED beads 31 and micro switches 32. The light guide column 2 is inserted into the light guide hole 11 of the housing 1 from the inner side of the housing 1. The light guide column 2 is loosely fitted with the light guide hole 11 of the housing 1, so that the top of the light guide column 1 is exposed on the outer side of the housing 1. The bottom of the light guide column 2 is provided with a protrusion 21, which is in corresponding contact with the micro switch 32 of the LED light panel 3. The LED beads 31 are located below the bottom of the light guide column 2, so that the light emitted by the LED beads 31 can be transmitted to the outside of the housing 1 through the light guide column 2.

[0030] Furthermore, a mounting sleeve 14 is provided inside the light guide hole 11, and the light guide post 2 is installed inside the mounting sleeve 14. A limiting shoulder 22 is provided on the side of the light guide post 2, and the limiting shoulder 22 is limited by the bottom of the mounting sleeve 14.

[0031] When installed, the LED light board 3 is snapped into the fixing groove 13. To facilitate installation, the opening direction of the fixing groove 13 is different, making it easier for the LED light board 3 to snap into place during installation. After snapping in place, the LED light board 3 can be stably fixed. At this time, the protrusion 21 of the light guide post 2 is in slight contact with the micro switch 32, and there is a loose fit between the light guide post 2 and the light guide hole 11. When the exposed surface of the light guide post 2 is pressed from the outer side of the housing 1, the protrusion 21 of the light guide post 2 presses down to actuate the micro switch 32, thereby switching the mode of the LED light board 3 and making different LED beads 31 emit light. Different colors of light allow the user to identify different modes of the charger.

[0032] The structure of this utility model enables the light guide column to simultaneously perform the functions of light transmission and pressure transmission. It also integrates operation feedback and status display through a single hole. Furthermore, no additional locking structure is required when installing the LED light board. The LED light board can be quickly installed by simply engaging the fixing slot, which facilitates installation, maintenance, and replacement.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
