Problems solved by technology

The main disadvantages of this mechanism are as follows: its installation location is near the D-pillar of the side wall. Belt layout, the installation location requirements are very strict; after the mechanism is installed on the body, the corresponding interior panels need to be specially designed to accommodate it, resulting in asymmetric structural space between the left and right sides of the car, which affects the appearance

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Electric tailgate driving mechanism of the present invention, as figure 1 As shown, the ball joints 1 at both ends are respectively fixed on the vehicle body and the tailgate, which is basically the same as the installation process of the gas spring of an ordinary SUV. sex.

[0021] The power tailgate drive mechanism, such as Figure 2-3 As shown, its shape can include three parts A, B, and C connected in sequence. Parts A and B do not move and are fixed parts. Part C moves relative to A and B with the opening and closing of the tailgate and is a moving part. The length of part B is the length of the stroke of the electric tailgate driving mechanism. The length of extension or shortening of the electric tailgate drive mechanism varies according to the maximum opening angle of the tailgate of each model and the specific installation p...

Abstract

The invention discloses an automobile power back door driving mechanism. The automobile power back door driving mechanism comprises a motor sleeve, a micro motor positioned in the motor sleeve, a planetary reducer, a screw rod sleeve, a multihead screw rod positioned in the screw rod sleeve, a nut sleeve, a multihead nut poisoned in the nut sleeve, wherein the multihead nut and multihead screw rod form a feed screw nut pair; a spring is sleeved outside the multihead screw rod and multihead nut; and the multihead screw rod is driven by the micro motor to drive the multihead nut to move relative to the multihead screw rod and the nut sleeve moves relative to the screw rod sleeve simultaneously. The mechanism has a simple and compact structure and small size, can be electrically started and closed when being energized, can extend and retract by manually driving the spring when not being energized and can realize free switching between motor operation and manual operation without any clutch.

Description

technical field [0001] The invention relates to an automobile tailgate drive mechanism, in particular to an automobile electric tailgate drive mechanism. Background technique [0002] In China, most of the existing SUVs still use gas springs to realize manual opening and closing of the tailgate. According to the development experience of foreign automobile markets, it will become a trend to change the tailgate of SUVs from manual to electric. Passengers only need to press the button (driver's seat button or key button), and the door will open and close automatically, which only takes a few seconds, which is convenient for passengers to take and place items. Especially in rainy and snowy weather conditions, it can avoid dirty hands when opening and closing the tailgate, and also provides a solution to the inconvenience caused by most female passengers when opening and closing the tailgate due to their low strength. For the sake of safety, the electric tailgate can also have...
