After the coupling 500 connects the motor assembly with the door shaft 800, if the brake 200 is in the unlocked state, the motor 100 operates and the motor 100 is stably pulled to rotate the door shaft 800 through the coupling 500, if the brake 200 is in the unlocked state, the motor 100 is locked, the coupling 500 stops pulling the door shaft 800 to rotate, and the vehicle door is in the closed state or the open state at this time, so that the coupling 500 can ensure the transmission stability between the motor assembly and the door shaft 800. In this scheme, a door actuating system corresponds a door axle 800 setting, namely, if the door is single open the door, then adopts a door actuating system, if the door is double open the door, then adopts two door actuating systems, so, the transmission efficiency of this scheme is high, simple structure, it is little to occupy the space in wind channel on the door, and do not influence the wind channel air-out effect, in addition, motor 100 converts the electric energy into kinetic energy, energy conversion efficiency is higher, and utilize the shaft coupling 500 transmission to belong to rigid transmission, no buffering stroke, the noise that the use produced has been reduced.
When the coupling 500 includes both the universal joint 510 and the expansion and contraction portion 520, the expansion and contraction portion 520 is located on the connecting shaft 530 of the coupling 500, and the expansion and contraction direction thereof is parallel to the axial direction of the connecting shaft 530. Further, in the present embodiment, referring to fig. 1 and 2, the coupling 500 is configured as a double universal coupling 500. It will be appreciated that the range of angles between the two connecting shafts 530 of the double universal joint 500 is relatively large, providing more options for the mounting location of the motor assembly, so as to fully utilize the space on the vehicle door and promote flexibility in the mounting layout. Of course, in other embodiments, the coupling 500 is configured as a single universal coupling 500, with two connecting shafts 530 connecting the output shaft of the motor 100 and the door shaft 800, respectively.
Further, in the present embodiment, referring to fig. 1 and 2, when the coupling 500 includes the telescopic portion 520, the telescopic portion 520 is disposed between the two universal joints 510 of the double universal coupling 500. Without loss of generality, the length of the connecting shaft 530 of the coupling 500, which connects the door shaft 800 or the output shaft of the motor 100, is shorter, the connecting shaft 530 between the two universal joints 510 can be provided for the telescopic part 520, and the telescopic direction of the telescopic part 520 is parallel to the distribution direction of the two universal joints 510, so as to adjust the distance between the two universal joints 510, and the connecting shaft 530 on the universal joints 510, which connects the door shaft 800 or the output shaft of the motor 100, can rotate around the universal joints 510, so as to better adapt to the installation position of the motor assembly, and in the running process of the vehicle, the door shaft 800 jumps, the telescopic part 520 stretches to compensate the position change caused by the displacement of the door shaft 800, the impact on the motor assembly is weakened, and the reliability of the door driving system is improved. Of course, in other embodiments, the telescopic portion 520 is disposed on the connecting shaft 530 of the universal joint 510 and the door shaft 800 or the output shaft of the motor 100, or the coupling 500 is made of a deformed material, and the deformation direction thereof does not interfere with the transmission direction of the coupling 500.
Specifically, in the present embodiment, referring to fig. 1 to 3, the motor assembly is disposed on the door tray 700 above the vehicle door, the output shaft of the motor 100 and the door shaft 800 are disposed at an included angle, and the output shaft of the motor 100 and the door shaft 800 are coaxially connected to the connecting shafts 530 at two ends of the universal joint 500, respectively. It should be noted that, the door tray 700 above the vehicle door has a space where the power supply assembly can be installed, the output shaft of the motor 100 located in the space forms an included angle with the door shaft 800, and the space does not interfere with the space of the air duct on the vehicle door, so that the extending direction of the output shaft of the motor 100 and the extending direction of the door shaft 800 on the door tray 700 are adapted by adjusting the included angle of the connecting shafts 530 at two ends of the double universal couplings 500, thereby improving the transmission efficiency of the motor 100 and the space utilization rate on the vehicle door. Of course, in other embodiments, the two connecting shafts 530 of the universal joint 500 are collinear, and the motor assembly may be mounted above the door shaft 800.
Further, in the present embodiment, referring to fig. 3, the door driving system further includes two brackets 600, one end of the motor assembly is correspondingly connected to one bracket 600, and the bracket 600 is used for mounting the motor assembly on the door tray 700. It should be noted that, each component in the motor assembly is distributed along the extending direction of the output shaft of the motor 100, and in the process that the motor 100 drives the door shaft 800 to rotate, the two ends of the motor assembly easily vibrate, so, one bracket 600 is correspondingly connected to one end of the motor assembly and fixed on the door tray 700, so as to directly resist the end of the motor assembly that is easy to vibrate, ensure the stability of the motor assembly, and reduce the running noise. Without loss of generality, the bracket 600 is secured to the door tray 700 by screwing. Of course, in other embodiments, the motor assembly may be welded directly to the door tray 700.
In an embodiment, referring to fig. 1 and 2, one connecting shaft 530 of the coupling 500 is connected to the motor 100 by a key connection, and the other connecting shaft 530 is used for key connection with the door shaft 800. It can be appreciated that the key connection can realize the circumferential fixation between the shafts, and the axial directions of the shafts can be relatively moved, so that the motor 100 can drive the door shaft 800 to stably rotate through the coupling 500, and can counter the axial vibration between the motor 100 and the door shaft 800, thereby improving the stability of transmission. Of course, in other embodiments, the coupling 500 may be welded, snap-fit, or the like to the motor 100 or door shaft 800.
In one embodiment, referring to fig. 5, the brake 200 is an energized brake 202, and the energized brake 202 is in a locked state when energized and is in an unlocked state when the energized brake 202 is de-energized. It can be appreciated that after the power-on brake 202 is powered off, the motor 100 is not bound by the power-on brake 202 any more, but can be in a free state or an electric state, if the motor 100 is in the electric state, the motor 100 can drive the vehicle door to open and close through the coupling 500; if the motor 100 is in a free state, a driver and a passenger can push the vehicle door to open and close, at this time, the opening and closing of the vehicle door are controlled without using a power supply of the vehicle, and the vehicle door can be opened and closed only by external force.
In another embodiment, referring to fig. 1, the brake 200 is a power-off brake 201, and the power-off brake 201 is in a locked state when power is off, and is in an unlocked state when power is on. It should be noted that, the time that the door needs to be locked is longer than the opening and closing time of the door, so when the door does not need to be driven to move, the power-off brake 201 is in the power-off state, and the motor 100 is locked, thereby reducing the consumption of electric energy by the power-off brake 201.
Further, in the present embodiment, referring to fig. 1 and 3, the door driving system further includes a brake handle 400, where the brake handle 400 is connected to the power-off brake 201, and the brake handle 400 is used to control the power-off brake 201 to switch between the unlocked state and the locked state. In this way, the passenger can achieve manual control of the de-energized brake 201 via the brake handle 400. It can be understood that the brake handle 400 can adjust the control relationship between the brake handle 400 and the motor 100 in the power-off brake 201, when the brake handle 400 is rotated to make the power-off brake 201 in the unlocked state, the motor 100 is in the free state, but because no power is supplied at this time, a driver can directly push the door to open and close so as to get on or off the vehicle, similarly, after the door is closed or opened in place, when the brake handle 400 is rotated to make the power-off brake 201 in the locked state, the motor 100 is locked by the power-off brake 201, and the door cannot be pushed, thereby ensuring the vehicle safety of the driver. The unlocked state and the locked state described in this paragraph are states in which no power is supplied to the electric power cut-off brake 201 and the motor 100, and the electric power cut-off brake 201 is switched between the unlocked state and the locked state only by the control handle.
In an embodiment, referring to fig. 1 and 3, the motor assembly further includes a transmission 300, an input end of the transmission 300 is connected to an output end of the motor 100, and an output end of the transmission 300 is connected to the coupling 500. In this way, the transmission 300 can adjust the transmission ratio output by the motor 100 to adapt to the driving force required for opening and closing the vehicle door, so as to ensure that the vehicle door is opened and closed at a stable speed. For example, the motor 100 adopts a specification with power of 24V and 40W, the transmission 300 adopts a planetary gear reducer with a speed ratio of 392.98:1, when the vehicle door driving system works, the motor 100 rotates, the speed reducer at the output end of the motor reduces the rotating speed and increases the torque, the speed reducer outputs power, and then the double universal coupling 500 drives the door shaft 800 to rotate, so that the opening and closing of the vehicle door are realized. Of course, in other embodiments, different power motors 100 and different speed ratios of the transmission 300 may be used in combination to accommodate different vehicle doors.
The utility model also provides a vehicle, which comprises a vehicle door and a vehicle door driving system, wherein the specific structure of the vehicle door driving system refers to the embodiment, and the vehicle adopts all the technical schemes of all the embodiments, so that the vehicle at least has all the beneficial effects brought by the technical schemes of the embodiments, and the detailed description is omitted. Wherein the door drive system is used to drive the door to rotate about its corresponding door axle 800.
The foregoing description is only of the optional embodiments of the present utility model, and is not intended to limit the scope of the utility model, and all the equivalent structural changes made by the description of the present utility model and the accompanying drawings or the direct/indirect application in other related technical fields are included in the scope of the utility model.
