Wireless transmission expansion device

Abstract

The invention relates to the technical field of expansion devices, in particular to a wireless transmission expansion device which comprises an expansion seat, a wireless transmission device and at least one antenna module. The expansion seat is provided with a base part, a containing space is formed in the base part, the two sides of the base part respectively extend to form a positioning clamping arm, and a clamping space is formed between the two positioning clamping arms; the wireless transmission device is arranged in the accommodating space; the antenna modules are arranged on the positioning clamping arms, and at least one antenna module is in signal connection with the wireless transmission device; therefore, the wireless transmission expansion device can be matched with the existing audio and video equipment or a portable camera which does not have a 4G transmission function or has no internal space to add the 4G function, so that the effect of instantly transmitting a large amount of audio and video information is achieved.

Description

[0001] This application is a divisional application of the patent application with the original application number 201811040070.4, the application date is 2018 / 9 / 7, and the invention name is "wireless transmission expansion device". technical field [0002] The invention relates to the technical field of extension devices, in particular to a wireless transmission extension device. Background technique [0003] With the progress and development of science, people's life has gradually become intelligent and convenient, especially many portable audio-visual equipment (3C products), which provide a lot of convenience for life, leisure or work. Since these portable audio-visual devices usually have functions such as video recording, recording, and photography, the obtained audio-visual information is first stored in the device, and then taken out or transferred out at an appropriate time. However, due to the large capacity of audio-visual information, it is easy to cause the cons...
