[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

It should also be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other.

[0019] Please see Figures 1 to 7 A preferred embodiment of this utility model provides an electrically operated light-blocking blade structure, which includes... Mounting plate 100 is used to fix the light fixture; A chassis 200 is rotatably connected to the mounting plate 100, and both the middle portion of the chassis 200 and the middle portion of the mounting plate 100 have light source exposed areas 201. Light-blocking blades 300 are provided in multiple form and are evenly distributed on the side of the chassis 200; The first drive mechanism 400 is provided in multiple ways, each corresponding to one of the number of light-blocking leaves 300. The first drive mechanism 400 includes a first motor 401 and a transmission assembly 402. The first motor 401 and the transmission assembly 402 are both mounted on the chassis 200. The power output end of the first motor 401 drives the light-blocking leaves 300 to rotate through the transmission assembly 402, so that the light-blocking leaves 300 can be opened or closed. The second drive mechanism 500 includes a second motor 501, a gear 503 disk 502 and a gear 503. The gear 503 disk 502 is fixedly connected to the mounting plate 100. The second motor 501 is mounted on the chassis 200. The power output end of the second motor 501 is fixedly connected to the gear 503. The gear 503 meshes with the gear 503 disk 502.

[0020] In this embodiment, the chassis 200 is formed by assembling a front cover 202 and a rear cover 203 to provide mounting space for the first drive mechanism 400 and the second motor 501. The rear cover 203 is located near the mounting plate 100, and both the first drive mechanism 400 and the second motor 501 are mounted on the rear cover 203. The number of light-blocking leaves 300 and the first drive mechanism 400 is preferably four.

[0021] According to the electric light-blocking blade structure of this utility model, the power output transmission component 402 of the first motor 401 drives the light-blocking blade 300 to rotate, causing the light-blocking blade 300 to open or close. Furthermore, the chassis 200 is rotatably connected to the mounting plate 100. A gear 503 is fixedly connected to the power output end of the second motor 501 mounted on the chassis 200. The gear 503 meshes with the gear 503 disk 502 mounted on the mounting plate 100. Therefore, when the chassis 200 rotates, it can drive the light-blocking blade 300 to rotate, adapting to different light-blocking angle requirements. It can be seen that the light-blocking blade 300 structure of this utility model, by setting two driving mechanisms, can respectively realize the opening, closing, and rotation of the light-blocking blade 300. The opening and closing amplitude and rotation angle are flexibly adjustable, with a high degree of automation, greatly facilitating users' requirements for lamp luminous efficacy.

[0022] For example, a limiting component 600 for limiting the rotation angle of the chassis 200 is provided between the chassis 200 and the mounting plate 100. Specifically, the limiting component 600 includes a first limiting sheet metal part 601, a second limiting sheet metal part 602, a first limiting post 603, and a second limiting post 604. The first limiting sheet metal part 601 and the second limiting sheet metal part 602 are both fixedly connected to the mounting plate 100, and the first limiting post 603 and the second limiting post 604 are both fixedly connected to the chassis 200. The chassis 200 can rotate 90 degrees forward relative to the mounting plate 100, causing the first limiting post 603 to abut against the first limiting sheet metal part 601, thereby achieving limiting. The chassis 200 can also rotate 90 degrees backward relative to the mounting plate 100, causing the second limiting post 604 to abut against the second limiting sheet metal part 602, thereby achieving limiting.

[0023] For example, the first motor 401 is preferably a geared motor, which can output greater torque and at the same time has a more stable output speed.

[0024] For example, the second motor 501 is preferably a stepper motor, which can precisely control the rotation angle and has high reliability.

[0025] For example, a sealing ring is provided at the joint between the front cover 202 and the rear cover 203, and a waterproof connector 204 for inputting electrical signals to the first motor 401 is provided on the rear cover 203. This design, when used with a waterproof spotlight, helps users avoid concerns about rain or other adverse conditions when using it outdoors. The waterproof connector 204 ensures that the first motor 401 receives electrical power and signals while achieving an IP65 waterproof rating.

[0026] For example, the mounting plate 100 has multiple mounting components 110 evenly distributed on it. Each mounting component 110 includes a mounting angle plate 111 and a rivet 112. One panel of the mounting angle plate 111 is fixedly connected to the mounting plate 100, and the rivet 112 is connected to the other panel of the mounting angle plate 111. During installation, the user can use the rivet 112 to fix the mounting angle plate 111 to the light fixture, making installation convenient.

[0027] For example, to better support the mounting plate 100, the chassis 200 has a plurality of rollers 205 evenly distributed on one side near the mounting plate 100, and the rollers 205 roll in cooperation with the mounting plate 100.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
