Problems solved by technology

[0007] However, in this prior art, there are following problems: when left for a long time in a low-temperature and high-humidity state, the electrical contact of the relay switch freezes and cannot be switched, and the drive current cannot be supplied to the switch body drive motor. Therefore, it is impossible to open and close the opening and closing body and other malfunctions.

Embodiment Construction

[0108] Below, refer to Figure 1 to Figure 18 An embodiment in which the driving device for the opening and closing body of the present invention is applied to the driving device for the opening and closing body for a vehicle in a door closer device for a vehicle will be described. Such as figure 1 As shown, the door closer device (the drive device for the vehicle opening and closing body) includes a back door (opening and closing body) 3 that opens and closes the rear opening (opening portion) 2 of the vehicle body 1 . The back door 3 is rotatably attached to the upper edge of the rear opening 2 about a rotation axis in the left-right direction (horizontal direction).

[0109] Such as figure 1 ,and Figure 8 ~ Figure 10 As shown, the door closer device includes a locking mechanism 10 fixed to the back door 3 . In addition, a striker S that engages and disengages the lock mechanism 10 is provided at the lower edge of the rear opening 2 of the vehicle body 1 . The lock mec...

Abstract

The purpose of the invention is to obtain a drive device for an opening / closing body that can reliably prevent malfunctions arising from the freezing of an electric contact of a relay switch. A control unit (60) is provided with: a freezing assessment unit (61) that determines that a relay switch (SW1, SW2, SW3) is frozen when the opening / closing body drive motor (27a) does not perform normal driving according to an operation condition for opening or closing the opening / closing body (3) and the temperature of the control unit (60) detected by a temperature detector (80) is at or below a prescribed value; and a freezing removal unit (62) that, when the freezing assessment unit (61) determines that a relay switch (SW1, SW2, SW3) is frozen, puts the device in a state in which drive current is not supplied to the opening / closing body drive motor (27a) and then supplies current intermittently for a prescribed number of times to the relay switch (SW1, SW2, SW3) to remove the freezing of the relay switch (SW1, SW2, SW3).

Description

technical field [0001] The present invention relates to a drive device for a vehicle opening and closing body such as a vehicle door (back door), a power trunk lid, and a swing door. Background technique [0002] Conventionally, as a driving device for an opening and closing body for a vehicle, there is known a driving device that includes an opening and closing body that opens and closes an opening of the vehicle body, and drives the opening and closing body to open and close by forward and reverse rotation. The opening and closing body driving motor, the storage battery that generates the driving current of the opening and closing body driving motor, the supply device that supplies the driving current generated by the battery to the opening and closing body driving motor, and the device that switches the forward and reverse rotation directions of the opening and closing body driving motor Switch device. At least one of the supply device and the switching device includes a...
