Problems solved by technology

However, the structures of these bullet-loading mechanisms are relatively complicated and difficult to assemble, so that the flashlight is very likely to break down or get stuck during the process of popping up and hiding. must have a certain storage space
Therefore, the application of these mechanisms will make it difficult to reduce the space occupied by the flash device as a whole, thus failing to adapt to the current trend of shrinking structural space of new cameras.

Embodiment Construction

[0019] The pop-up flash mechanism 2 of the present invention can be applied to a digital camera, and it is installed on the camera body 1. When the camera is not working, please refer to Figure 1A As shown, the flashlight body 20 is in a horizontally closed state, and its light-emitting part faces downward, so as to realize concealment in appearance. When the camera is working and an auxiliary light source is required, please refer to Figure 1B As shown, the flashlight body 20 is in a pop-up state, and its light-emitting part faces forward.

[0020] Please refer to figure 2 As shown, it is a preferred embodiment of the pop-up flashlight mechanism 2. The flashlight mechanism 2 mainly includes a flashlight body 20, a support base 30 for supporting the flashlight body 20 and fixing it on the camera body, and enabling the flashlight to The main body 20 operates the driving device 40 .

[0021] The flashlight body 20 has a lamp body 23 and an upper cover 21 and a lower cover 2...

Abstract

The present invention discloses an upspring type flash mechanism. It mainly includes a supporting seat, flash self-body mounted on the supporting seat, first torsion spring which is mounted on the supporting seat and can be used for providing an upwards spring force and a drive device placed close to flash self-body. Besides, said invention also provides its working principle.

Description

【Technical field】 [0001] The invention relates to a pop-up flashlight mechanism, in particular to a pop-up flashlight mechanism which is applied to a camera and can be hidden. 【Background technique】 [0002] As a kind of light reinforcement device, flashlight has long been widely used on cameras to provide auxiliary light for photographing. However, today's new cameras (including ordinary cameras, advanced system digital cameras or digital video cameras) make the lens correspondingly larger in order to achieve high-magnification optical zoom, and the commonly used built-in flash can no longer meet its performance. OVF, Optical Viewfinder) is gradually replaced by electronic viewfinder (EVF, Electronic Viewfinder), camera design tends to be miniaturized, and the structure space of the camera is reduced. A pop-up flash that pops up when needed is imperative. [0003] The pop-up flash with hidden function currently used in the industry is to hide the flash housing with the li...
