[0027] In order to make the technical problem solved by the present invention, technical solutions and beneficial effects clearer, the accompanying drawings and the following embodiments, the present invention will be described in further detail. It should be understood that the specific embodiments described herein are merely used to explain the present invention and are not intended to limit the present invention.
[0028] like Figure 1 to 2 , An electric structure of a vehicle door drive according to an embodiment of the present invention, apparatus 3 comprises a power transmission mechanism 4 and a hinge 5;
[0029] The hinge 5 comprises a fixed page 51 and rotate the movable page connected to the fixed page 51 of 52, active page 52 may be connected to the fixed page 51 by rotating the rotary shaft 53; FixedPage 51 fixed to the vehicle body 1, the active page 52 is fixed to the door 2 ;
[0030] Power means 3 is fixed to the vehicle body 1, specifically, directly fixed to the vehicle body 1 can also be fixed to other parts of the vehicle body 1 and fixed relative to the power device 3 is positioned outside the hinge 5;
[0031] The transmission mechanism 4 is disposed between the power unit 3 and a hinge 5, and the transmission is connected between the output terminal and the activities of the power unit 52 on page 3.
[0032] In particular, the page 51 may be fixed by the first fixing screw S1 is fixed to the vehicle body 1, a second active page 52 by a fixing bolt fixed to the door 2 S2.
[0033] In use, the device provides power to the vehicle power supply 3, output power of the power unit 3 to the transmission mechanism 4, transmission mechanism 4 driven by the active page 52 page 51 fixed with respect to rotation, due to the fixed active page 52 and the door 2, the door 2 with the active page 52 rotate together, implement the functions of the electric switch 2 controls the door.
[0034] Electric drive vehicle door structure according to an embodiment of the present invention, as compared with the prior art, the power plant 3 Direct drive transmission mechanism 4, transmission mechanism 4 and is directly driven by the living hinge 52 on page 5 of rotation, thereby realizing an electric switch controls the door 2 conducive to simplify the structure, to shorten the transmission chain, thereby facilitating reduction in weight and cost; the power unit 3 is fixed to the vehicle body 1, and a drive mechanism implemented to the power unit 3 to the active page transmission 52 is connected to 4, without the traditional hinges structure 5 undue changes easily disposed; avoids the problem of the power unit 3 and the transmission mechanism 4 is disposed in the inner hinge 5, resulting in complicated structure of the hinge 5 and which affects the transmission power limited switching function 2 of the door.
[0035] In one embodiment, if Figure 1 , The power unit 3 includes a drive motor 31 and the reduction mechanism 32, the reduction mechanism 32 is connected to the input terminal of the output terminal of the drive motor 31, the output of the speed reduction mechanism 32 is connected to the transmission mechanism 4. Since the power means 3 is provided on the outer hinge 5, thus having a sufficient spatial arrangement of the driving motor 31 and the reduction mechanism 32, when used, to supply power to the vehicle driving motor 31, the driving motor 31 through a speed reduction mechanism 32 to reduce speed and increase torque, then the output power to the drive mechanism 4, to better match the power demands of the door switches 2.
[0036] Specifically, the drive motor 31 connection 34 to an external power supply system by a motor vehicle.
[0037] In one embodiment, if Figure 1 FIG, 6 further comprising a protective cover, the protective cover 6 is fixed to the fixed page 51, the deceleration mechanism 32 is fixed to the protective cover (6), located within a shroud 6 gear 4. Since the fixed body 1 on page 51 and fixed, so either by the protective cover 6 is fixed to the power unit 3 on a vehicle body, avoiding additional fixing structure provided in the power unit 3, but also by reducing the shield 6 on the dust transfer means 4 accumulation, reduce maintenance difficulty.
[0038] Specifically, the protective cover 6 may be fixed to the third fixing bolt fixed S3 page 51, fourth speed reduction mechanism 32 via a fixing bolt fixed to S4 through the shield 6.
[0039] In one embodiment, if Figure 1 , The transmission mechanism 4 includes a driving member 41 and the driven member 42, member 41 is connected to the active output terminal of the power device 3 (with 32, 41 output 32 is connected to the speed reduction mechanism reduction mechanism active component), the slave fixed to the movable member 42 on page 52 and 41 driven by the active member. Active member 41 and the driven member 42 through the power unit 3 and the transmission between the active page 52, a simple structure.
[0040] like Figure 2 , The driving process of the preferred embodiment of the present invention is as follows: the output terminal 3 of the power unit 7 is rotated about the drive axis to drive the rotation of the drive member 41, 42 driven by rotation of the drive member 41 of the driven member in parallel therewith, the movable member movable follower page 52 42 about the hinge axis 8 of rotation, thereby achieving the door switch 2.
[0041] In one embodiment, if Figure 1 , The power unit 3 also comprises a power output shaft 33, output shaft 33 connected to the output 32 of the deceleration mechanism, active member 41 is a sleeve secured to the drive gear disposed on the output shaft 33, the driven member 42 is engaged radially outer fan driven tooth driving gear. The output shaft 33 is provided to facilitate the arrangement of the driving gear, a driven member 42 driven toothed segment selection is conducive to miniaturization of the driven member 42.
[0042] Preferably, a rotation shaft 53 when the driven sector gear sleeved on the rotating shaft 53, so as to increase the force-2 reliable door switch.
[0043] In particular, the axis of rotation of the power output shaft 53 parallel to the axis 33.
[0044] In one embodiment, if Figure 1As shown, the lower end opening of the protective cover 6, the reduction mechanism 32 is fixed to the top side of the shroud 6, and the power output shaft 33 is disposed inside the shroud 6, the active gear, and the slave to the protective cover 6.Compact, easy assembly, reliable connection, and protective cover 6 can effectively protect the active gear and from the slave fan, avoiding the reliability of the integration affecting the transmission.
[0045] The embodiment of the present invention also provides a vehicle including a vehicle body 1, a door 2, and an electric drive structure of the door described above.
[0046] The above is only preferred embodiments of the invention, and is not intended to limit the invention, any modifications, equivalents, and improvements made within the spirit and principles of the present invention, should be included in the protection range of the present invention.Inside.
