Abstract
The invention discloses a power-operated tailgate driving mechanism with an overload separation protection device. The power-operated tailgate driving mechanism comprises a lead screw sleeve, a multi-head lead screw, a motor sleeve, a motor, a planetary gear reducer, an overload separation protector and a connector, wherein the multi-head lead screw is positioned in the lead screw sleeve, the motor is positioned in the motor sleeve, an input end of the planetary gear reducer is connected to a power output shaft of the motor, an input end of the overload separation protector is rigidly connected to an output end of the planetary gear reducer, an output end of the overload separation protector is connected to the multi-head lead screw through the connector, the lead screw sleeve can be close to and far away from the motor sleeve, and one end of the motor sleeve back to the lead screw sleeve is connected to a power-operated tailgate, so that the whole driving mechanism can be more effectively protected. The power-operated tailgate driving mechanism is compact in structure and small in size, and mounting space can be saved.
Description
Technical field
The present invention relates to the automobile power back door driving mechanism field, a kind of electronic door driving mechanism with overload separation protective device specifically is provided.
Background technology
At home in existing automobile, the tail-gate great majority still utilize air spring to realize the hand switch door, but along with going from strength to strength of China Auto Market, the passenger uses the continuous renewal of car idea, the switching mode of automobile tail gate has increased the motor switch pattern on the basis of hand switch pattern, and the motor switch pattern becomes a kind of trend of automobile tail gate switching mode gradually.
More ripe electronic tail-gate system mainly contains two kinds in the market, and a kind of is the pinion and-rack door driving mechanism, it be mainly by motor, clutch, gear, rack-driving spoke and be connected to tail-gate and tooth bar on connecting rod etc. consist of.This structure is to realize the switch of tail-gate by the moving connecting rod that is fixed on gear and tail-gate of motor-driven gear tooth bar subband, but this structure noise in the process of switch gate is large, and transmission is unstable; And this construction profile size is bigger than normal, needs to take larger boot space and space in installation process.
Another kind is the rocker arm door driving mechanism, and it is mainly to be made of the conglomerate of motor and clutch, secondary gear pair, rocking arm and connecting rod etc.This structure is to shake the reciprocating swing of arm by the motor-driven gear subband, and then drivening rod is realized the switch of tail-gate.This structure requires very harsh when mounted to the installation site, easily cause the asymmetric of vehicle structure space, affects attractive in appearance.
Summary of the invention
In order to overcome defects, the invention provides a kind of electronic door driving mechanism with overload separation protective device, this drives structure is compact, volume is little, can save installing space; And this drives structure can also reduce noise, avoids extra load to act on motor, reaches the integrally-built purpose of protection.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of electronic door driving mechanism with overload separation protective device, motor and the planetary reducer of described motor sleeve is located in bull screw mandrel, motor sleeve and the location that comprise the screw mandrel sleeve, is positioned at described screw mandrel sleeve, the input of described planetary reducer is connected in the power output shaft of described motor, it can be used for reducing rotating speed, promote moment of torsion, coupling inertia; Also be provided with overload separation protector and an a connection piece, the input of described overload separation protector is rigidly connected in the output of described planetary reducer, and the output of described overload separation protector is connected in described bull screw mandrel by described connector; When motor-driven bull screw mandrel rotates, promote described screw mandrel sleeve can be mutually near and away from described motor sleeve, and described motor sleeve dorsad an end of described screw mandrel sleeve be connected in electronic tail-gate.
Wherein said overload separation protector is to guarantee that the load of transmitting is no more than the mechanical device of limit value, and when load surpassed the setting permissible value, the torque limiter on it just can skid, and consumes extra moment of torsion, thereby has effectively protected driving mechanism and motor.This overload separation protector is prior art, and its operating principle does not elaborate at this.
As a further improvement on the present invention, described connector by two mutually the concave, convex plastic parts of buckle form, can play the effect that reduces noise.
As a further improvement on the present invention, the external diameter of described motor sleeve is greater than the external diameter of described screw mandrel sleeve, and described overload separation protector and connector are all located and be located in described motor sleeve.
The invention has the beneficial effects as follows: drive the rotation of bull screw mandrel by the motor-driven planetary reducer is set, the sleeve that drags on screw mandrel is done straight reciprocating motion, thereby realizes the automatic switch of tail-gate; And the present invention also arranges one and can avoid extra load to act on overload separation protector and the flexible connecting member that can reduce noise on motor between planetary reducer and bull screw mandrel, thereby can better reach the purpose of the whole driving mechanism of protection.Compact conformation of the present invention, volume are little, can save installing space.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below with reference to Fig. 1 to a preferred embodiment of the present invention will be described in detail.
Electronic door driving mechanism with overload separation protective device of the present invention comprises screw mandrel sleeve 7, is positioned at the bull screw mandrel 5 of described screw mandrel sleeve, described motor sleeve is located in motor sleeve 6 and location motor 1 and planetary reducer 2, the external diameter of described motor sleeve is greater than the external diameter of described screw mandrel sleeve, the input of described planetary reducer is connected in the power output shaft of described motor, described planetary reducer can be used for reducing rotating speed, promote moment of torsion, coupling inertia; Also be provided with an overload separation protector 3 and a connection piece 4 in described motor sleeve, the input of described overload separation protector is rigidly connected in the output of described planetary reducer, and the output of described overload separation protector is connected in described bull screw mandrel by described connector; When motor-driven bull screw mandrel rotates, promote described screw mandrel sleeve can be mutually near and away from described motor sleeve, and described motor sleeve dorsad an end of described screw mandrel sleeve be connected in electronic tail-gate.
In the present embodiment, described connector by two mutually the concave, convex plastic parts of buckle form, can play the effect that reduces noise.
