As shown in fig. 1, some embodiments of the present utility model provide an electric drive for a vehicle, which includes a drive mechanism 1, a transmission mechanism, a mounting bracket 4, and a side frame bracket 5. The mounting frame 4 is provided with a through hole 41. The transmission mechanism comprises a screw rod 32, a sliding block 31, a push-pull rod 33 and a connecting block 34. Wherein the drive mechanism 1 is configured to drive the screw 32 to rotate about its axial direction.

The slide block 31 is sleeved on the screw rod 32 and is in threaded connection with the screw rod 32. That is, the slider 31 is provided with an opening of an internal thread, and the screw 32 is provided with an external thread at the outer circumference thereof, and the external thread of the screw 32 is screwed with the internal thread of the opening.

The push-pull rod 33 is fixedly connected with the slide block 31. The push-pull rod 33 passes through the through hole 41 and is movable in the radial direction of the through hole 41. Illustratively, one end of the push-pull rod 33 is fixedly coupled to the slider 31, while the other end of the push-pull rod 33 extends through the via 41. The inner diameter of the through hole 41 is adapted to the outer diameter of the push-pull rod 33. The push-pull rod 33 can only move along its length due to the limitation of the limiting mechanism (e.g. the through hole 41) on the mounting frame 4. When the driving mechanism 1 drives the screw rod 32 to rotate, the push-pull rod 33 can only move along the length direction, and meanwhile, due to limitation (such as limitation of a limiting mechanism on the mounting frame 4), the sliding block 31 cannot rotate, so that the rotation of the screw rod 32 is converted into linear motion of the sliding block 31 and the push-pull rod 33.

For the connection block 34, it is fixed to the other end of the push-pull rod 33 and is located on the side of the mounting frame 4 remote from the slider 31. That is, the slider 31 and the connection block 34 are respectively located at both ends of the push-pull rod 33. The connecting block 34 has a pin (not shown in the drawings) and the side frame 5 has a slide groove 51. The pin is disposed in the chute 51 and can slide along the length direction of the chute 51, and the pin and the chute 51 can rotate relatively. Wherein the moving direction of the push-pull rod 33 is perpendicular to the length direction of the pin. One of the mounting bracket 4 and the side bracket 5 is fixed to the door, and the other is fixed to the vehicle body.

The following examples are described with respect to the mounting bracket 4 being fixed to the vehicle body and the side bracket 5 being fixed to the vehicle door.

When the above-mentioned driver is in operation, the driving mechanism drives the screw 32 to rotate, and the screw 32 can be converted into a linear motion of the push-pull rod 33.

Referring to fig. 2, in the process of the linear motion of the push-pull rod 33, the pin 341 of the connection block 34 can be pushed to perform the linear motion along the length direction of the push-pull rod 33. Since the pin 341 is located in the chute 51, the pin 341 may be configured to rotate the door (e.g., in a direction indicated by an arrow curve in fig. 2) by changing a position of the pin in the chute 51.

It should be noted that, when the mounting frame 4 is fixed to the door and the side bracket 5 is fixed to the vehicle body, fig. 2 is a schematic view of the door as a reference, that is, the door is set not to move as a whole, but the vehicle body rotates. In this case, the arrow-headed curve in the figure indicates the rotation direction of the vehicle body.

The whole structure of the driver is smaller, and the driver does not swing in the working process, so that the space required by the arrangement of the driver is smaller, and the driver is beneficial to the arrangement of the driver in a vehicle door or a vehicle body; meanwhile, in the opening or closing process of the vehicle door, the vehicle door is mainly pushed by the linear motion of the push-pull rod, so that the space between the push-pull rod and the through hole is sealed, and the whole driver is sealed and waterproof conveniently. In addition, the positions of the pins in the sliding grooves are changed in the rotation process of the vehicle door, and surface contact is formed between the pins and the sliding grooves, so that abrasion in the moving process of the vehicle door can be reduced, and the service life of the vehicle door is prolonged.

In some embodiments, the mounting frame 4 is further sleeved with a sealing ring at the through hole 41. Thus, the whole driver can be sealed and waterproof better.

In some embodiments, as shown in fig. 1, the connection block 34 includes a connection portion disposed perpendicular to the push-pull rod 33, and extension portions are disposed at two ends of the connection portion, where an extension direction of the extension portion is consistent with a length direction of the push-pull rod 33. The pin is fixed on the extension part and is arranged perpendicular to the extension part.

In some embodiments, referring to fig. 1-3, a sliding slot 51 is disposed through the side bracket 5, a pin 341 penetrates the sliding slot 51, and two ends of the pin 341 are fixed on the extending portion of the connecting block 34. In this way, the pin 341 completely passes through the sliding groove 51, so that the pin 341 is always positioned in the sliding groove 51 in the moving process of the pin 341 compared with the sliding groove 51, and the moving stability of the pin 341 is improved. In addition, both ends of the pin 341 may be fixed to the extension of the connection block 34 by bolts.

For example, the connection block 34 is provided with openings through which both ends of the pin 341 pass. And both ends of the pin 341 are provided with external threads, which can be fixed to the connection block 34 by nuts.

In some examples, the outer diameter of pin 341 is adapted to the width of chute 51. This allows the pin 341 to slide only in the length direction of the slide groove 51 during the sliding in the slide groove 51, thereby improving the stability of the movement thereof.

In some embodiments, the outer circumference of pin 341 and/or the inner side of chute 51 is provided with a lubricious coating. That is, the outer circumference of the pin 341 is provided with a lubrication coating, or the inner side of the chute 51 is provided with a lubrication coating, or both the outer circumference of the pin 341 and the inner side of the chute 51 are provided with a lubrication coating. The smooth sliding of the pin 341 in the slide groove 51 is facilitated by the lubricating coating, thereby facilitating the opening or closing of the door.

In some embodiments, the drive mechanism 1 comprises a drive motor, the output end of which is sleeved with a driving gear. One end of the screw rod 31 is sleeved with a driven gear, and the driving gear is meshed with the driven gear. This allows axial rotation of the lead screw 31. The meshing of the driving gear and the driven gear is also advantageous in improving the stability of the rotation of the drive mechanism 1 driving the screw 31. The output end of the driving motor may be provided with a speed reducer, so that the rotational speed of the screw 31 may be controlled as needed.

In some embodiments, the drive motor is a reversible motor. This arrangement can realize forward and reverse driving of the screw shaft 31. For example, when the screw 31 is rotated in a forward direction (e.g., clockwise), opening of the door may be achieved; and when the screw 31 is rotated in the reverse direction (e.g., counterclockwise), the closing of the door can be achieved. Therefore, the driver can be used for opening or closing the side door, and the actual use of a user is facilitated.

In some embodiments, the drive further comprises a gear box in which a transition gear is provided, the driving gear and the driven gear being connected by the transition gear. By the arrangement, the driving gear can drive the driven gear by utilizing the transition gear, so that the driving gear and the driven gear can be prevented from being meshed by setting larger gear diameters. Therefore, the space occupied by the gear can be saved by utilizing the transition gear, so that the arrangement of the driver in the vehicle door or the vehicle body is convenient.

In some examples, the number of teeth of the transition gear is different from the number of teeth of the driving gear and the number of teeth of the driven gear, so that the number of teeth of the transition gear and the number of teeth of the driving gear, and the number of teeth of the transition gear and the number of teeth of the driven gear can be used to control the rotation speed of the driven gear and the screw rod 31 connected with the driven gear, thereby better controlling the opening and closing speed of the side door.

In some examples, the driving gear and the driven gear are both positioned in the gear box, so that the stability of the working process of the gears can be further protected, and the gears are prevented from being interfered by external sundries.

In some embodiments, one end of the lead screw 32 is fixed to the mount by a bearing. For example, in the case that the driven gear is disposed on the lead screw 32, one end of the lead screw 32 far away from the driven gear is fixed on the mounting frame 4 through a bearing, so that stability of the working process of the lead screw 32 can be further ensured, and shaking during the working process of the lead screw 32 is avoided.

The electric actuator for a vehicle is not limited to application to a side door of an automobile, and may be applied to a trunk door, a window of an automobile (e.g., a sunroof), etc., according to actual needs, and the application is not limited thereto.

While preferred embodiments of the present utility model have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. It is therefore intended that the following claims be interpreted as including the preferred embodiments and all such alterations and modifications as fall within the scope of the utility model.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present utility model without departing from the spirit or scope of the utility model. Thus, it is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
