Description
DRIVER FOR VEHICLE SIDE DOOR AND VEHICLE COMPRISING THE SAMETechnical Field
[0001] The present disclosure relates to the application of vehicle technology, in particular to a driver for opening / closing a side door of a vehicle, which comprises a motor and an actuating member loaded by a motor via a transmission system. The present disclosure also relates to a vehicle comprising the driver.Background Art
[0002] Today's vehicles are increasingly equipped with comfort functions. For example, in order to facilitate access to the vehicle and promote aesthetic and aerodynamic styling, the vehicle is not equipped with an external door handle. It is also conceivable to have an outer door handle, which, however, only transmits the switch signal to the vehicle door lock for opening. A so-called opening device, door mover, or door position holder / door opener is used to ease and automate boarding and help board, for example, a vehicle without an external door handle.
[0003] The existing driver for opening / closing the vehicle door has the following disadvantages: the driver includes a conventional mechanical stopper, but the vehicle door can be only suspended in a fixed gear, instead of at any opening angle. At present, there are also electric door mechanisms, most of which involve such parts as cables / racks / hinge shafts, featuring numerous parts, complex structure and large space occupied.
[0004] Therefore, it is necessary to provide an improved driver for opening and closing vehicle doors.Summary

[0012] Optionally, the holding device comprises a holding mechanism motor and a holding mechanism, and the holding mechanism motor can act on the driving chain for the driving motor via the holding mechanism to prevent the actuating member from acting.

[0033] Figs. 1 and 2 schematically show a driver 100 for a vehicle side door according to an embodiment of the present disclosure.
[0034] As shown in Fig. 1, the driver 100 may include a housing 1, in which an accommodating cavity is formed, and a driving device 2 and a holding device 3 may be accommodated in the accommodating cavity.
[0035] The driver 100 may further include an actuating member 4, one end of which may be arranged in the accommodating cavity, and the other end may extend out of the housing 1. The actuating member 4 can be driven by the driving device 2 to move linearly, for example, to transmit thrust and / or pull to a component (not shown) connected to the actuating member, thereby driving the component to move.
[0036] As an example, the driver 100 may be used to open / close a vehicle side door, and the actuating member 4 may be a rod-shaped member such as a connecting rod or a push rod. The driving device 2 can be arranged on a side door of a vehicle, and one end of the actuating member 4 in the form of a connecting rod or a push rod is connected to a driving force output end of the driving device 2, and the other end of the actuating member 4 is bolted to a pillar A or pillar B of the vehicle body, so that the actuating member 4 can transmit thrust / pull to the side door to open or close the side door.
[0037] The holding device 3 can exert a holding action on the driving device 2 to prevent the actuating member 4 from acting under the influence of an external force (e.g. when the vehicle is on a steep slope or when the wind acts on a side door) , so as to keep the actuating member 4 and the components connected thereto in place. For example, when the driver 100 is installed in a side door of a vehicle, the side door can be held in a suspending position by the holding device 3, as described in detail below.
[0038] As shown in Figs. 1 and 2, the driving device 2 may include a driving motor 20 with an output shaft and a transmission system 22, and the driving motor 20 may exert a driving action on the actuating member 4 through the output shaft and the transmission system 22.
[0039] The transmission system 22 may include a lead screw assembly 24. The lead screw assembly 24 may include a lead screw 240 and a slider 242 in threaded connection with the lead screw 240. The slider 242 may be connected to the actuating member 4.
[0040] The transmission system 22 may further include an assembly consisting of a transmission worm 26 and a worm wheel 28. The worm 26 may be arranged at an end of the output shaft of the driving motor 20, and the worm wheel 28 may be arranged at one end of the lead screw 240 and cooperate with the transmission worm 26 to transmit the driving force to the lead screw 240. The output shaft of the driving motor 20 and the transmission worm 26 may be connected, for example, by means of a key connection structure therebetween.
[0041] The output shaft of the driving motor 20 and the lead screw 240 may be arranged such that their central axes are perpendicular to each other. Owing to the perpendicular arrangement between the motor output shaft and the lead screw, and the transmission mode where the worm wheel cooperates with the worm, a large transmission ratio and a compact structure can be formed.
[0042] The driver 100 may further include a guide member 5, and the actuating member 4, the guide member 5, and the lead screw 240 may be connected to each other via the slider 242 and arranged such that the actuating member 4 is positioned between the guide member 5 and the lead screw 240 when viewed in the direction parallel to the central axis of the output shaft of the driving motor 20.
[0043] For example, when the driver 100 is installed at a side door of a vehicle, “the direction parallel to the central axis of the output shaft of the driving motor” may be a substantially vertical direction. In this case, the guide member 5, the actuating member 4 and the lead screw 240 are sequentially arranged from top to bottom (see Fig. 2) .
[0044] Since the guide member 5, the actuating member 4 and the lead screw 240 are sequentially arranged from top to bottom, the output shaft of the driving motor 20 and the transmission worm 26 can be arranged adjacent to the lead screw 240 located below the driver, thus occupying as little space in the vertical direction as possible to create a compact structure. Moreover, the transmission of driving force from the lead screw 240 to the actuating member 4 can be improved, because the actuating member 4 and the lead screw 240 can be arranged adjacent to each other.
[0045] As shown in Fig. 1, the central axes of the guide member 5, the actuating member 4 and the lead screw 240 may be parallel to each other. The central axes of the guide member 5 and the lead screw 240 may be in a same plane, and the central axis of the actuating member 4 may be in the same plane or may be offset from the plane. In the embodiment shown in Fig. 1, the central axis of the actuating member 4 is offset towards the output shaft of the driving motor 20 with respect to the plane where the central axes of the guide member 5 and the lead screw 240 are located. In other words, in Fig. 1, the actuating member 4 is arranged between the guide member 5 / the lead screw 240 and the output shaft of the driving motor 20 when viewed in the horizontal direction.
[0046] In this way, the slider 242 can move smoothly along the guide member 5, driving the actuating member 4 to move linearly, and the space of the guide member 5, the actuating member 4 and the lead screw 240 in the vertical direction can be further compressed.
[0047] As better shown in Fig. 1, one end (the lower end in Figs. 1 and 2) of the slider 242 can be threadedly connected to the lead screw 240, so that the slider 242 can be driven to move by the rotation of the lead screw 240. The other end (the upper end in Figs. 1 and 2) of the slider 242 can be sleeved on the guide member 5, so that the slider 242 can slide relative to the guide member 5 under the rotary drive of the lead screw 240. In addition, the middle part of the slider 242 is connected to one end of the actuating member 4 by bolts or pins, for example, to drive the actuating member 4 to move linearly.
[0048] In the embodiment shown in Figs. 1 and 2, the lead screw 240, the slider 242 and the actuating member 4 are arranged such that when the slider 242 moves towards the end of the lead screw 240 provided with the worm wheel 28, the actuating member 4 is urged to further extend out of the housing 1, and when the slider 242 moves away from the end of the lead screw 240 provided with the worm wheel 28, the actuating member 4 is urged to retract to the accommodating cavity inside the housing 1. For example, the driver 100 can be installed inside a side door of a vehicle, and the end of the actuating member 4 in the form of a push rod extending out of the housing 1 can be hinged to the vehicle body. When the slider 242 is driven to move towards the end of the lead screw 240 provided with the worm wheel 28, the actuating member 4 applies a thrust to the vehicle body, pushing the vehicle door to pivot in the opening direction (the direction away from the vehicle body) to automatically open the vehicle door. When the slider 242 is driven to move away from the end of the lead screw 240 provided with the worm wheel 28, the actuating member 4 applies a pulling force to the vehicle body, pulling the vehicle door to pivot in the closing direction (the direction towards the vehicle body) to automatically close the vehicle door.
[0049] The holding device 3 according to one embodiment of the present disclosure will be described below with reference to Figs. 3 and 4.
[0050] As shown in Fig. 3, the holding device 3 may include a holding mechanism motor 30 and a holding mechanism 32. As described in detail below, the holding mechanism motor 30 can exert a holding action on the driving chain for the driving motor 20 via the holding mechanism 32 to prevent the actuating member 4 from acting, thereby holding the positions of the actuating member 4 and the components connected thereto (not shown) .
[0051] The holding mechanism motor 30 may be arranged such that the central axes of the output shaft of the holding mechanism motor 30 and the output shaft of the driving motor 20 are perpendicular to each other, and the output shaft of the holding mechanism motor 30 is adjacent to and parallel to the lead screw 240, as shown in Figs. 1 and 2. In this way, the spatial layout inside the driver 100 is optimized, and a compact structure is ensured in the vertical direction even though the holding device 3 is added.
[0052] As better shown in Figs. 3 and 4, the holding mechanism 32 may include a brake wheel 34, a cam member 36 and a brake member 38. The brake member 38 may be arranged between the brake wheel 34 and the cam member 36.
[0053] The brake wheel 34 can be fixedly connected to the side of the transmission worm 26 opposite to the driving motor 20.
[0054] The cam member 36 may include a gear part 360 and a cam part 362 arranged coaxially. The gear part 360 can cooperate with the holding mechanism worm 302 provided at the end of the output shaft of the holding mechanism motor 30, so that the holding mechanism motor 30 can drive the cam member 36 to rotate via the holding mechanism worm 302. The cam part 362 of the cam member 36 may include a cam bottom 364 and a cam top 366 that is raised (in the radial direction) relative to the cam bottom 364.
[0055] Due to the control by the cam part 362 (see Fig. 4) of the cam member 36, the brake member 38 can move between a first position in which the brake member 38 is engaged with the brake wheel 34 to exert a holding effect on the brake wheel 34, and a second position in which the brake member 38 is disengaged from the brake wheel 34 to release the brake wheel.
[0056] In the embodiment shown in Figs. 3 and 4, the brake member 38 may include a spring 380, a first brake block 382, a second brake block 384 and a friction brake block 386. The first brake block 382 may have a substantially rectangular shape, for example. The first brake block 382 may include a groove extending along its length direction, which is parallel to the axis direction of the output shaft of the holding mechanism motor 30. The spring 380, the second brake block 384 and the friction brake block 386 are assembled in the groove of the first brake block 382, so that they can move with the first brake block 382.
[0057] The first end of the spring 380 abuts against an end wall of the groove of the first brake block 382, the second end is connected to one end of the second brake block 384, and the other end of the second brake block 384 is connected to the friction brake block 386, and at least a part of the friction brake block 386 extends from the first brake block 382 towards the brake wheel 34. The spring 380 may be a compression spring. The spring 380 may be used to apply a biasing force to the brake member 38 to bias the brake member 38 towards the cam member 36 and the brake wheel 34.
[0058] The first brake block 382 of the brake member 38 may be configured to abut against the cam part 362 of the cam member 36. The operations of the brake member 38 and the cam member 36 will be described in detail below.
[0059] Figs. 3 and 4 show a state in which the brake member 38 of the holding mechanism 32 is in the first position (i.e., the friction brake block 386 is engaged with the brake wheel 34 to exert a holding effect on the brake wheel 34) . As shown in Fig. 4, in the first position, the first brake block 382 abuts against the cam top 366 of the cam part 362. When the holding mechanism motor 30 drives the holding mechanism worm 302 to rotate so as to drive the cam member 36 to rotate in a separation direction (counter-clockwise in Fig. 4) , the spring 380 in a compressed state at this time can exert a biasing effect on the first brake block 382, so the first brake block 382 can always contact the contour of the cam part 362 until it abuts against the cam bottom 364 of the cam part 362. During this period, the spring 380, the second brake block 384 and the friction brake block 386 also move along with the first brake block 382 in the direction away from the brake wheel 34, so that the brake member 38 reaches the second position. In the second position, the brake member 38 (specifically, the friction brake block 386) is disengaged from the brake wheel 34, releasing the brake wheel 34 and allowing it to rotate (and thereby allowing the transmission worm 26 to rotate) , then allowing the actuating member 4 to act.
[0060] In the second position, if the holding mechanism motor 30 drives the holding mechanism worm 302 to rotate in the opposite direction, the cam member 36 is driven to rotate in the engagement direction (clockwise in Fig. 4) . Due to the rigid pushing action of the cam member 36, the spring 380 is elastically compressed, so the first brake block 382 can always contact the contour of the cam part 362 until it abuts against the cam top 366 of the cam part 362. During this period, the compressed spring 380 pushes the second brake block 384 and the friction brake block 386 to move towards the brake wheel 34, causing the brake member 38 to reach the first position again (i.e. the position shown in Figs. 3 and 4) . In the first position, the brake member 38 engages with the brake wheel 34 by means of the friction brake block 386, thereby exerting pressure on the brake wheel 34 to prevent the brake wheel 34 from rotating (and thereby prevent the transmission worm 26 from rotating) , and then prevent the actuating member 4 from acting, so that the vehicle door can be kept at any opening angle.
[0061] The friction brake block 386 is made of a friction material to hold and prevent the brake wheel from rotating. The friction material can be synthetic rubber or other friction materials.
[0062] The holding device 3 may further include a signal switch 40. The signal switch 40 may be a contact switch. When the brake member 38 reaches the first position, a protrusion on the cam member 36 will press against the signal switch 40 (see Fig. 4) , causing the switch to be turned on and output a current signal. On the contrary, if the brake member 38 leaves the first position, the protrusion on the cam member 36 will not contact the signal switch 40, leaving the switch off and without a current signal output.
[0063] The application of the driver to a vehicle side door is exemplarily described herein, but its application is not limited thereto. The driver for a vehicle side door can also serve for other functions of a vehicle, such as electrically closing the front cover, rear cover or sliding door. However, these are also just examples, which shall not limit the application field of the driver.
[0064] It will be appreciated that the embodiments described above are exemplary, and can be improved by a skilled person in the art, and the structures described in the embodiments can be combined freely if without conflicts in structure or principle.
[0065] The preferred embodiments of the present disclosure are described above in detail, and it is apparent to a person skilled in the art that various changes can be made without departing from the scope and spirit of the appended claims, and the present disclosure is not limited to the exemplary embodiments illustrated in the Specification.
