During installation, the bottom of the flash unit contacts and secures itself to the metal contacts of the camera's hot shoe, establishing electrical connection and signal transmission. One contact on the camera's hot shoe interface has a high-level signal when the flash is powered on.

[0003] However, existing hot shoe lights often lack the function of automatic power on / off, requiring manual operation, which is inconvenient. Therefore, there is an urgent need for a camera component that uses a level signal to control power on / off based on the hot shoe interface to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a camera component that controls the power on and off based on a level signal of the hot shoe interface, so as to solve the problem mentioned in the background art that existing hot shoe lights often do not have the function of automatic power on and off, and often require manual switching.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a camera assembly for power on / off control based on a hot shoe interface, comprising a hot shoe mount, a center contact, high and low level contacts, a locking knob, a housing, and a flash. The center contact is located at the center of the bottom of the hot shoe mount, and the high and low level contacts are located at the left end of the bottom of the hot shoe mount. The high and low level contacts are provided with pins for detecting high and low levels. The locking knob is fixedly connected to the top of the hot shoe mount, the housing is fixedly connected to the top of the locking knob, and the flash is fixedly connected to the top of the housing.

[0006] Preferably, a lithium battery and a PCB board are disposed inside the housing, and a display screen and control buttons are disposed on the rear side of the housing, both of which are electrically connected to the lithium battery and the PCB board.

[0007] Preferably, the center contact, high and low level contacts, and flash lamp are all electrically connected to the lithium battery and PCB board inside the housing.

[0008] Preferably, the high-low level change of the high-low level contact causes the power on / off.

[0009] Preferably, both the housing and the flash lamp are switched on and off by changes in the level of high and low level contacts.

[0010] Preferably, the hot shoe is connected to the camera hot shoe, and the center contact and the high and low level contacts are electrically connected to the camera hot shoe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This camera assembly, which uses a level signal to control power on / off based on a hot shoe interface, is equipped with high and low level contacts. The hot shoe mount is installed on the camera hot shoe mount. One contact of the camera hot shoe interface has a high level signal when the camera is powered on. When the camera is powered on, the level change can be detected through the high and low level contacts. The camera is powered on by the level change of the hot shoe interface contact when the camera is powered on. When the camera is powered off, no high level is provided to power off the camera. The operation is more convenient and effortless, and there is no need to manually turn the device on or off. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 The present invention provides an embodiment of a camera assembly for power on / off control based on a hot shoe interface, comprising a hot shoe mount 1, a center contact 2, high and low level contacts 3, a locking knob 4, a housing 5, and a flash 6. The center contact 2 is located at the center of the bottom of the hot shoe mount 1, and the high and low level contacts 3 are located at the bottom left end of the hot shoe mount 1.
