Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0029] The ultrasonic motor used in the present invention is a TULA (ultra-miniature ultrasonic linear motor) product developed by a Korean company (Piezoelectric Technology Co., Ltd) and a national research institution (KIST: Korea Institute of Science and Technology). TULA is a motor that converts ultrasonic vibrations caused by the piezoelectric effect of single-layer or multi-layer piezoelectric ceramics (vibrators) into linear motion and rotary motion. The root part of the drive shaft is fixed with piezoelectric ceramics, and the friction body (moving body) that preloads the drive shaft clamps the main shaft. When it stops, it will stop completely due to friction force, and there will be no micro...

Abstract

The invention relates to a double-drive lifting device for a camera and electronic equipment comprising the lifting device. The double-drive lifting device for the camera comprises an installation frame, ultrasonic motors and sliding blocks, wherein the two sides of the installation frame are symmetrically provided with two ultrasonic motors, a main shaft of each ultrasonic motor is provided withone sliding block, and the camera is fixedly installed between the two sliding blocks. According to the double-drive lifting device for the camera and the electronic equipment comprising the lifting device, the ultrasonic motors are adopted, the ultrasonic motors are about 10 times faster than electronic motors in response speed, drive noise is quite low, the holding force is high when no power isapplied, because no electromagnetic coils are used, therefore, no free electron wave will be generated, and no electric quantity will be consumed when no action is performed.

Description

technical field [0001] The invention belongs to the mechanical field, and relates to a smart phone, a tablet computer, and a laptop computer, especially a dual-drive lifting device for a camera and electronic equipment including the lifting device. Background technique [0002] CN109257472A discloses a telescopic device and a mobile phone, which has a frame, a screw, a slide block and a driving device for driving the screw to rotate; the screw is arranged on the frame to rotate; the slide block is provided with an internal thread through hole; the screw passes through Through the internal thread through hole and threaded with it; it is characterized in that: the driving device includes a motor and a transmission gear set; the motor is arranged on one side of the screw; one end of the screw is coaxially fixed with a driven gear; the output shaft of the motor The screw rod is driven to rotate through the cooperation of the transmission gear set and the driven gear transmission...
