Description
Technical Field
The utility model belongs to the technical field of the charger equipment technique and specifically relates to a waterproof base of charger box body is related to.
Background
Electric bicycle has become the important vehicle of people's trip, electric bicycle is chargeable, it is the charger to support with it, the charger is when charging for electric bicycle battery, can produce a large amount of heats, the heat needs in time to ventilate and discharge, otherwise can influence the work efficiency and the life of charger, consequently all be equipped with exhaust fan and vent on the charger, but the charger exposes outside usually, when outdoor use meets rain and snow weather, have moisture to get into the charger in from the vent easily, can damage facilities such as charger internal circuit board during serious, especially weld the foot face on the circuit board, if be stained with water, the short circuit risk is very high.
Disclosure of Invention
The utility model relates to a solve the easy problem that damages facilities such as the inside circuit board of charger by moisture infiltration in the charger, provide a rational in infrastructure, can block moisture, keep apart waterproof charger box body waterproof base with the external world with the leg face on the circuit board.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the waterproof base of charger box body, the box body includes upper cover, base, and the base is equipped with the circuit board and can fixes the screw hole post of circuit board, the base in the bottom surface be equipped with the waterproof strip of at least a convex annular, circuit board bottom side hug closely with the waterproof strip surface of annular, bottom surface, circuit board bottom side form waterproof airtight space in the waterproof strip of annular and the base. The existing circuit board is fixed in the base through the screw hole column, the surface of a welding leg on the circuit board is arranged below the base, and the surface of the welding leg on the circuit board needs a certain accommodating height to accommodate the welding leg, so the screw hole column protrudes out of the inner bottom surface of the base, but the circuit board is fixed on the screw hole column, and a gap which can be entered by moisture is formed at the side edge of the screw hole column, so the circuit board is easy to damage; the annular waterproof strip can block a gap between the side edge of the circuit board and the inner bottom surface of the base, so that water is blocked outside the annular waterproof strip, and the inner ring of the annular waterproof strip is a closed waterproof space of a welding leg surface on the circuit board; compared with the structure that the waterproof glue layer is formed by gluing the welding leg surfaces on the circuit board adopted by some products, the circuit board can be detached for maintenance after the circuit board breaks down; in addition, an annular waterproof strip can be arranged on the outer side of the welding foot surface on the circuit board, and the function of the annular waterproof strip is the same as that of the annular waterproof strip arranged on the inner surface of the base.
Preferably, the surface of the annular waterproof strip is provided with at least one annular groove, and a waterproof rubber strip is arranged in the annular groove. The annular waterproof strip and the base are made of the same material, if the material is hard, the annular waterproof strip and the circuit board cannot be tightly pressed close to each other between the welding leg surfaces, the waterproof effect is affected, and the waterproof effect can be solved by adopting a waterproof adhesive tape.
Preferably, an annular waterproof film is arranged between the surface of the annular waterproof strip and the bottom side surface of the circuit board. The waterproof strip of annular and the same material of base, if the material is harder, can not form between the fillet weld face on waterproof strip of annular and the circuit board and closely press close to, influence water-proof effects, adopt the waterproof film of annular to solve.
Preferably, the bottom side surface of the circuit board is provided with a waterproof rubber ring matched with the annular waterproof strip shape. The waterproof strip of annular and the same material of base, if the material is harder, can not form between the fillet face on waterproof strip of annular and the circuit board and closely press close to, influence water-proof effects, adopt waterproof gluey ring to solve.
Therefore, the utility model discloses following beneficial effect has: (1) the structure is reasonable, and the influence of moisture on the welding leg surface on the circuit board can be prevented; (2) the solder foot surface on the circuit board is isolated from the outside.
Drawings
Fig. 1 is a schematic structural diagram of the base of the present invention.
Fig. 2 is a schematic perspective view of fig. 1.
In the figure: 1. base 2, screw hole column 3, annular waterproof strip 4, base inner bottom surface
5. Annular groove 6, waterproof adhesive tape.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, a charger box waterproof base comprises an upper cover and a base 1, wherein the base 1 is provided with a circuit board and a threaded column 2 capable of fixing the circuit board, a protruding annular waterproof strip 3 is arranged on the inner bottom surface of the base 1, the bottom side surface of the circuit board is tightly attached to the surface of the annular waterproof strip 3, and the annular waterproof strip 3, the inner bottom surface 4 of the base and the bottom side surface of the circuit board form a waterproof closed space; the surface of the annular waterproof strip 3 is provided with an annular groove 5, and a waterproof adhesive tape 6 is arranged in the annular groove 5;
in addition, an annular waterproof rubber sheet can be arranged between the surface of the annular waterproof strip 3 and the bottom side surface of the circuit board; or, a waterproof rubber ring matched with the annular waterproof strip 3 in shape is arranged on the bottom side surface of the circuit board.
The specific implementation process is that a waterproof adhesive tape 6 is added into an annular groove 5 of an annular waterproof strip 3 in the base 1, then the circuit board is fixed on the threaded column 2, and the annular waterproof strip 3, the inner bottom surface 4 of the base and the bottom side surface of the circuit board form a waterproof closed space, so that moisture can be prevented from entering and damaging the bottom side welding feet of the circuit board.
