[0038] The current rotating rear door of a car needs to utilize a related door drive device to achieve the purpose of automatic opening, closing and limiting. The door drive device usually adopts an electric limiter or an electric strut. However, most of the electric limiters or electric struts realize the opening, closing and limiting of the door by horizontal extension and contraction, and there is a situation that the door cannot be opened and closed at a large angle. At the same time, due to the installation of the electric limiter or the electric strut, which is limited by the layout space inside the car body or the layout space outside the car, the driving direction of the electric limiter or the force direction of the push rod of the electric strut cannot be changed at a large angle, resulting in the door being unable to achieve large-angle opening, closing and limiting.

[0039] Among them, the door drive device can be used in a vehicle, and the vehicle can refer to a car or an aircraft, wherein the car can be a large vehicle, a small vehicle, a special vehicle, etc. For example, according to the vehicle model, the vehicle in this application can be a sedan model, an off-road model, a multi-purpose vehicle (MPV) model or other models.

[0040] Reference Figures 1 to 8 In one embodiment of the utility model, the door drive device 100 includes a guide rod 1, a push rod 3 and a power assembly 4, the guide rod 1 is used to connect with one of the vehicle body 200 and the vehicle door 300, and a slider 2 is provided on the guide rod 1; one end of the push rod 3 is rotatably connected to the slider 2, and the other end of the push rod 3 is used to be rotatably connected to the other of the vehicle body 200 and the vehicle door 300; the power assembly 4 includes a driving member 41 and a transmission bar 42, the driving member 41 is transmission-connected with the transmission bar 42, the transmission bar 42 is connected to the slider 2, and the transmission bar 42 is used to drive the slider 2 to slide along the guide rod 1; the door drive device 100 is configured to be projected along the rotation axis of the vehicle door 300, and the push rod 3 can swing relative to the guide rod 1.

[0041] By connecting the guide rod 1 to one of the vehicle body 200 and the vehicle door 300, and utilizing one end of the push rod 3 to be rotatably connected to the slider 2 on the guide rod 1, the two ends of the push rod 3 are respectively rotated relative to the guide rod 1 and the vehicle door 300; the transmission bar 42 is driven to rotate by the driving member 41 of the power assembly 4, and the slider 2 is driven to move along the length direction of the guide rod 1 by the transmission bar 42; specifically, when the vehicle door 300 is in a closed state, the slider 2 is located at one end of the guide rod 1, and when the vehicle door 300 needs to be opened, the transmission bar 42 is driven to move by the driving member 41 of the power assembly 4, and the transmission bar 42 moves and drives the slider 2 to move to the other end of the guide rod 1, and the slider 2 drives and drives the push rod 3 one end of the push rod 3 moves; the power component 4 causes relative rotation between the push rod 3 and the guide rod 1, and at the same time, the push rod 3 and the car door 300 generate relative rotation. Since the car door drive device 100 is configured to be projected along the rotation axis of the car door 300, the push rod 3 can swing relative to the guide rod 1, so that the push rod 3 pushes the car door 300 to open; the driving member 41 drives the slider 2 to slide along the guide rod 1 through the transmission bar 42, which has the advantages of high transmission efficiency and good reliability, and can provide a stable driving force for one end of the push rod 3 to move along the guide rod 1. Since the push rod 3 can swing relative to the guide rail, the rotation angle range of the push rod 3 is increased, thereby realizing the opening, closing and limiting of the car door 300 in a large angle range.

[0042] The guide rod 1 is installed on the inner bottom wall of the vehicle body 200 by bolt connection, welding or bonding. One end of the push rod 3 is rotatably connected to the slider 2 on the guide rod 1, and the other end of the push rod 3 is rotatably connected to the vehicle door 300. When the power component 4 drives the slider 2 to move along the length direction of the guide rod 1, relative rotation can be generated between the push rod 3 and the guide rod 1, and between the push rod 3 and the vehicle door 300.

[0043] In some embodiments, reference Figure 2 , Figure 3The push rod 3 is used to swing from one side of the guide rod 1 to the other side of the guide rod 1 in the length direction.

It should be noted that the large-angle opening and closing and limiting means that the maximum opening angle of the door 300 is greater than 90° and less than 270° under the action of the push rod 3.
