Detailed ways

The following are preferred embodiments of the present invention, but they do not limit the protection scope of the present invention.

Referring to Figures 1-4, a fully automatic telescopic focusing flashlight of the present invention includes a lamp cap 1, a lamp body 2 and a lamp tail 3, and an optical lens 4 and a luminous body 5 are arranged inside the lamp cap 1, and the lamp body 2 An electric telescopic focusing device for changing the distance between the optical lens 4 and the illuminant 5 is arranged inside, and the illuminant 5 is fixed on the electric telescopic focusing device. The lamp body 2 is provided with a lithium battery pack. The lamp body 2 of the present invention is divided into two sections, front and rear, which are screwed together, and a sealing ring is provided at the screw joint, an electric telescopic focusing device is installed on the front section of the lamp body 2, a lithium battery pack is installed on the rear section of the lamp body 2, and the lamp body The body is designed for the front and rear ends, mainly to facilitate the installation of the electric telescopic focusing device in the front section, simplify the installation procedure and improve the installation efficiency.

The electric telescopic focusing device includes a power assembly 6 capable of forward and reverse rotation, a deceleration assembly 7 connected to the power assembly 6, a rotary screw 8 connected to the deceleration assembly 7, and a moving block 9 screwed to the rotary screw 8, The moving block 9 axially slides in the lamp body 2 in the circumferential limit, and the luminous body 5 is fixed at the front end of the moving block 9; the electric telescopic focusing device also includes a first switch and a second Two switches. Described rotary screw rod 8 is a plastic part. The rear end of the moving block 9 is provided with a threaded hole, which is matched with the external thread of the rotating screw rod 8 .

The lamp body 2 is provided with a front limit travel switch 10 and a rear limit travel switch 11 along the moving direction of the moving block 9, and the moving block 9 is located between the front limit travel switch 10 and the rear limit travel switch 11. The aforementioned front limit travel switch 10 and rear limit travel switch 11 are electrically connected to the power assembly 6 . When the moving block 9 touches the front limit travel switch 10 or the rear limit travel switch 11, the power supply of the power assembly 6 can be cut off and stop rotating.

Said moving block 9 is limited and axially sliding in the lamp body 2 means that the inner wall of the lamp body 2 is provided with a chute along the moving direction of the moving block 9, and the outer side of the moving block 9 is provided with lugs that are slidably fitted in the chute. . Avoid moving block 9 circumferential rotations.

There are two or more chutes, and the number of lugs is the same as that of the chutes.
