Problems solved by technology

After such a configuration is assembled as a whole, due to the weak structural strength of the metal plate, it is easy to deform the metal plate due to external force, causing the zoom key to shake and the gap is too large, and the texture of the overall electronic device will be reduced.
[0003] Specifically, the current general zoom key structure, because the middle frame is a one-piece electroplated part and the zoom key is a structure composed of zoom twist, metal plate parts and screws, not only the number of parts is large, but the overall strength is weak , it is also very complicated to assemble, which leads to an increase in assembly cost and man-hours

Abstract

A zooming key structure comprises a zooming key, a first middle frame part and a second middle frame part. The first middle frame part is provide with a first clamping portion and a first body, and the first clamping portion extends out from the first body and is positioned on one side of the zooming key. The second middle frame part is provided with a second clamping portion and a second body, and the second clamping portion extends out from the second body and is positioned on the other side of the zooming key. The first clamping portion and the second clamping portion are clamped with each other to form annular holding space, and the zooming key is surrounded by the first clamping portion and the second clamping portion and fixed to the annular holding space.

Description

technical field [0001] The invention relates to a zoom key structure, in particular to a zoom key structure applied to portable electronic devices such as cameras, video cameras or mobile phones. Background technique [0002] The zoom key structure of the current portable electronic devices such as cameras, video cameras or mobile phones usually uses a middle band to fix the zoom key on the body, so as to facilitate the user to adjust the focus. Generally speaking, the manufacturing method of the middle frame is to open the mold first, then carry out plastic injection molding, and finally carry out electroplating. However, the shape of the middle frame is generally irregular, and there are some holes or grooves on the middle frame that need to be matched with some parts of the electronic device, such as zoom keys, power jacks, data transmission jacks, and the like. The more complex the shape, the more complex the mold opening will be. For injection molding, the required ho...
