Description

An integrated electric pole device

technical field

The utility model relates to an electric strut device for a vehicle, in particular to an integrated electric strut device adopting a two-stage planetary gear reduction box.

Background technique

The struts currently used on vehicles are mainly installed on both sides of the tailgate of the vehicle. The strut is filled with high-pressure gas, and after turning the tailgate manually through the self-locking point, it will be stretched or shortened under the left and right of the high-pressure gas. However, since it needs to manually provide power to turn over the self-locking point when opening, when the tailgate is large or heavy (especially for female drivers), it will be difficult to open or close the tailgate. In addition, there are models with a higher chassis. After the tailgate is opened, it will be at a relatively high position. For drivers who are not tall, it will also be difficult for the tailgate to close.

For electric struts, the work of the strut motor can be controlled by the control box to realize automatic extension or shortening. Thereby realize the automatic opening and closing of tailgate. At present, a small number of electric struts have appeared on the market, but due to the design problem of the existing electric struts, the strut motor is installed beside the main body of the strut, which looks like two long and short pipes side by side in appearance. . Such a design leads to a large volume of the strut, which cannot be applied to ordinary models. It can only be used in models that have reserved installation space in the early stage of vehicle design. The scope of use of the electric strut is limited.

Detailed ways

The preferred embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, so as to make a clearer definition of the protection scope of the utility model.

Referring to Fig. 1, the utility model comprises a transmission rod, a motor group 1, a planetary gear reducer 2, a screw clutch 3, an auxiliary spring 4 and a fixed casing 5, and the motor group 1 is composed of a DC motor, an end cover and a wire harness protective cover Composed of several parts, the planetary gear reducer 2 is provided with an integrally designed reduction housing, the planetary gear reducer 2 is internally provided with an internal gear, the reduction housing is provided with grooves, and the planetary gear reducer The reducer 2 is connected with the fixed casing 5 through the groove on the reduction casing. One end of the planetary gear reducer 2 is provided with a connection through hole, and the other end of the planetary gear reducer 2 is provided with a metal connector. The gear reducer 2 is connected to the motor group 1 and the screw clutch 3 respectively through connecting through holes and metal connectors. The screw clutch 3 includes a screw and a clutch device, and the screw is connected to the transmission rod. An auxiliary spring 4 is arranged on the outside of the transmission rod.

It is worth noting that the end cap is provided with round holes for wiring convenience.

It should be noted that the planetary gear reducer 2 adopts a two-stage reduction planetary gear reducer.

The working principle of the utility model: when the electric strut is compressed and shortened, the motor group 1 is energized and rotates clockwise to drive the planetary gear reducer 2, and through the conversion of the planetary gear reducer 2, the screw clutch 3 is driven to shorten, and at the same time, the auxiliary spring 4 Compression; when the electric strut is extended, the motor group 1 is energized and rotates counterclockwise, driving the planetary gear reducer 2, through the conversion of the planetary gear reducer 2, driving the screw clutch 3 to elongate, and at the same time, the auxiliary spring 4 elongation. During the whole process, the fixed shell always fixes and protects all the above-mentioned parts.

This design scheme is mainly composed of motor group, planetary gear reducer, screw clutch group, auxiliary spring, fixed shell and other parts. The motor group is an assembly composed of a DC motor, an end cover, and a wire harness protective cover, which can provide power for the strut to work and is the power source for the strut to work. There is a round hole in the end cover, which can meet the needs of motor wire routing. The wire harness protection cover is a transitional part connecting the vehicle and the strut to protect the motor wire harness. The planetary gear reducer is a two-stage reduction planetary gear reducer. The reducer casing adopts an integrated design, which integrates the internal gears of the two-stage planetary gears into one body, and the reducer casing is designed with a concave hole assembled with the fixed casing. Grooves and other fixed structures. The gear box connects the motor group and the screw clutch group through the hole at the tail and the metal at the head. Through the motion transmission of the internal gear, the rotation of the motor is converted into the thrust or compression force of the strut. The screw clutch group is a screw with a clutch device, which also adopts an integrated design. The elongation and shortening of the strut is realized by the screw, and the clutch is a protection device to prevent overloading. The auxiliary spring is a spring that assists the movement of the strut. The fixed casing is a casing that fixes all parts, and also has a protective function of preventing foreign objects from impacting.
