Description

Technical Field

[0001] The utility model belongs to the technical field of the battery installation of a shaver, and particularly relates to a battery fixing structure of a shaver. Background Technique

[0002] Electric shavers are divided into two categories according to the blade movement mode: rotary type and reciprocating type. The former has a simple structure, less noise, and moderate shaving force; the latter has a complex structure, large noise, but large shaving force and high sharpness. Rotary electric shavers can be further divided into several types according to the external structure, such as straight tube type, elbow type, electric hair clipper type, and double-head type. The first two types have a relatively simple structure, and the latter two are more complex. Electric shavers can be divided into three types according to the type of prime mover: DC permanent magnet motor type, AC / DC universal series-wound motor type, and electromagnetic vibration type.

[0003] At present, the battery of a shaver is usually fixed by using a large bracket to completely wrap the battery. This structural method has the disadvantages of complex parts, high mold and parts costs. For this reason, we propose a battery fixing structure of a shaver. Content of the Utility Model

[0004] The purpose of the utility model is to provide a battery fixing structure of a shaver, so as to solve the problems of complex parts, high mold and parts costs existing in the existing structural method of installing and fixing the battery of a shaver mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A battery fixing structure of a shaver, comprising a battery, a fixing card and a PCB board. Fixing cards are arranged on the surfaces at both ends of the top of the PCB board. The two sides at the bottom of the fixing card are in a clamped state with the outer sides of both ends of the PCB board. The battery is stably placed on the top of the fixing card. Jacks are respectively opened on the surfaces in the middle of both ends of the PCB board. Electrode plates are inserted into the jacks. One side at the top of the two electrode plates is in close contact with the positive and negative electrodes of the battery respectively by welding, and the bottom of the electrode plate is fixedly connected with the PCB board by welding.

[0006] Preferably, the two ends at the bottom of the fixing card extend downward to the lower part of the PCB board, and buckles are arranged on the inner sides of the two ends at the bottom of the fixing card. Buckle grooves are opened at the positions of the PCB board corresponding to the buckles of the fixing card. The fixing card is fixedly connected with the PCB board in a clamping manner through the buckles and the buckle grooves provided.

[0007] Preferably, a welding part is arranged at the bottom of the electrode plate. The welding part is inserted into the jack and extends to the bottom of the PCB board.

[0008] Preferably, a welding position is provided at the position of the bottom jack of the PCB board, and the welding part at the bottom of the electrode piece passes through the jack and extends to the welding position to be fixedly connected to the PCB board by welding.

[0009] Preferably, an arc-shaped groove is formed in the middle of the top surface of the fixing card, and the arc-shaped groove is closely attached to the outer periphery of the bottom of the battery.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. First, the fixing card is fixed on the PCB board in a snap-fit manner by using the buckle feet and the buckle slots. Then, both ends of the fixing card are welded to the battery and the PCB board by welding the electrode piece. The outer peripheral surface of the bottom of the battery is in close contact with the arc-shaped groove, so as to realize the installation and fixation of the battery. This way of fixing the battery not only has small parts and a simple structure, reducing the costs of the mold and parts, but also the battery welding operation is convenient, fast, and simple, and the fixation is firm and reliable.
