Problems solved by technology

This approach has the following disadvantages: the carbon brush will wear out during operation, and if the worn carbon powder accumulates in the commutator segment isolation groove, the adjacent commutator segment will short circuit, resulting in motor failure; in addition, the carbon brush is a wear part It will affect the life of the motor; it is necessary to add an encoder at the end of the motor to feed back the motor actuation information to the control module; the maximum efficiency of the carbon brush motor is generally about 65%, and the working current is relatively large; the carbon brush motor will generate electric sparks when commutating , will generate electromagnetic interference

Embodiment Construction

[0043]In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0044] It should be noted that when an element is said to be "fixed" to another element, it may be directly fixed to the other element or may be fixed to the other element through an intermediate element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or connected to the other element through intervening elements. Unless otherwise specified, the terms "first" and "second" in this document are only used to distinguish each component, element, step, etc. in the specification, rath...

Abstract

The invention discloses an electric jackstay which comprises an outer sleeve, an outer guide pipe, an inner guide pipe, a motor, a lead screw, a first connector and a second connector, wherein the motor and the outer guide pipe are arranged in the outer sleeve in the axial direction of the outer sleeve; the motor is connected with the lead screw; the inner guide pipe is in screw-thread fit with the lead screw; the inner guide pipe moves under guiding of the outer guide pipe; the inner guide pipe is in rotation stop fit with the outer guide pipe; the first connector and the second connector arearranged at two ends of the outer guide pipe separately; the first connector is fixed at the end part of the outer sleeve; the second connector is fixed at the end part of the inner guide pipe; and the motor is a coreless brushless motor. The electric jackstay is stable in working, unlikely to loss efficacy and long in service life, does not need an encoder to reduce the manufacturing cost, is high in efficiency, does not generate electric spark and can obtain a better electromagnetic interference inhibition effect.

Description

technical field [0001] The invention relates to the technical field of vehicle accessories, in particular to an electric strut. Background technique [0002] At present, the automobile tailgate struts on the market all use DC carbon brush motors, which mainly rely on the carbon brush motor to drive the screw rod for linear motion after being decelerated by the gearbox, thereby driving the tailgate to open or close. This approach has the following disadvantages: the carbon brush will wear out during operation, and if the worn carbon powder accumulates in the commutator segment isolation groove, the adjacent commutator segment will short circuit, resulting in motor failure; in addition, the carbon brush is a wear part It will affect the life of the motor; it is necessary to add an encoder at the end of the motor to feed back the motor actuation information to the control module; the maximum efficiency of the carbon brush motor is generally about 65%, and the working current is...
