Description

Technical Field

[0001] The invention relates to the technical field of automobile side sliding doors, and in particular to a brushless motor driving device for automobile side sliding doors. Background Art

[0002] A car side sliding door, also known as a sliding door or electric side sliding door, is a special door design that is mainly used to improve the practicality and convenience of the vehicle. Compared with traditional hinged doors, side sliding doors slide along the side of the car body when opening and closing, rather than opening outwards. This design has significant advantages in many aspects. First, side sliding doors are more convenient to use in narrow spaces. For example, in tight parking spaces or when there is limited space around, side sliding doors can effectively avoid the risk of collision with neighboring cars due to the door opening. Secondly, it is also easier for passengers, especially the elderly or children with limited mobility, to get on and off the car, because the door does not need to open outwards, reducing the space requirements for getting on and off the car. In addition, side sliding doors are designed with more emphasis on safety. Many modern side sliding doors are equipped with sensors and motors that can automatically sense obstacles and stop sliding when encountering resistance to prevent pinching accidents. This feature is particularly important in family cars, especially those with children. In commercial vehicles, such as vans and multi-purpose vehicles, the use of side sliding doors is more common. They not only improve the efficiency of passengers getting on and off the car, but also facilitate cargo transportation. The driver can easily load and unload cargo from the side without being restricted by traditional door opening methods.

When the brushless motor body 182 is started, the speed of movement of the first side sliding door is higher than that of the second side sliding door, so that the first side sliding door can move in front of the second side sliding door, thereby providing a larger entry and exit space when the door is fully opened, and passengers carrying large luggage or wearing loose dresses get on and off the car, ensuring convenience and elegance.

[0041] Embodiment 3: This embodiment is intended to promote the solution of the erroneous operation problem caused by the instantaneous current impact or unexpected failure when the motor starts.
