Description

Technical Field

[0001] This utility model relates to the field of motor control technology, and more specifically to a control device for a window lift motor. Background Technology

[0002] In vehicle window systems, the power windows for the driver and passenger sides are among the most frequently used basic functions for drivers. In existing technology, this function typically involves directly controlling the forward and reverse rotation of the window regulator motor via a main window switch. When the driver presses or releases the switch, the motor is powered on, driving the glass up and down; when the switch is released, the motor is de-energized, and the glass stops moving.

[0003] However, during long-term use, especially in humid and hot overseas regions or coastal environments with high humidity and salt spray, the reliability of vehicle electrical components faces significant challenges. Due to high ambient humidity and high salt content in the air, electrical contact points are prone to oxidation or increased contact resistance, leading to unstable current conduction. When users frequently or simultaneously operate the driver and passenger side window lift functions, such as pressing the driver and passenger side window lift switches at the same time, or continuing to press and hold the lift switch after the glass is raised to the top, the motor is in a stalled or near-stalled state, causing a sharp increase in instantaneous current. At this time, the main window switch must bear excessive operating current, which can easily cause its internal contacts to burn out, fuse, or even burn out the switch module, leading to window lift failure and other malfunctions.

[0004] Currently, a relatively mature solution in China utilizes a control architecture of "main window regulator switch + body control module (BCM) or pre-control module" to achieve intelligent management of window operation. When motor stall or prolonged high-load operation is detected, the control module performs overcurrent protection or power-off control to prevent damage to the motor and switch. However, this solution requires adding BCM interface logic to the vehicle's electrical architecture or redeveloping the pre-control module, involving high software and hardware development costs and a long system verification cycle. For some models targeting specific overseas markets, this solution is difficult to meet the demands of rapid mass production and market adaptation in terms of both cost and timeline.

[0005] Therefore, there is an urgent need for a window lift motor control device that does not rely on BCM or pre-control modules and can be implemented by optimizing motor control logic. This device can effectively prevent the main lift switch from burning out due to overcurrent while ensuring functional consistency, thereby improving system reliability and service life. Utility Model Content

[0006] The purpose of this utility model is to provide a control device for a window lift motor. By setting a driver's side window lift relay and a passenger side window lift relay, it can prevent large current from passing through the switch, thereby avoiding damage to the switch.

[0008] In another embodiment, the device further includes a secondary lifter switch; The auxiliary window regulator switch is located between the main window regulator switch and the passenger side window relay; The auxiliary window regulator switch is used to control the raising and lowering of the passenger-side window; The main elevator switch is also used to control the on / off state of the auxiliary elevator switch.

[0009] In another embodiment, the main lift includes a driver's side switch; The driver's side switch is connected to the driver's side window relay and is used to control the raising and lowering of the driver's side window.

[0011] In another embodiment, the main lifter further includes a secondary lifter switch control switch; The auxiliary lift switch control switch is connected to the auxiliary lift switch, and the auxiliary lift switch control switch is used to control the on / off state of the auxiliary lift switch.

[0017] Please see Figure 1 , Figure 1 This is a schematic diagram of a window regulator motor control device. The device includes: a main window regulator switch, which connects to the driver's side window regulator motor and the passenger side window regulator motor, and is used to control the raising and lowering of the driver's side window and the passenger side window; a driver's side window regulator relay is provided between the main window regulator switch and the driver's side window regulator motor, and a passenger side window regulator relay is provided between the main window regulator switch and the passenger side window regulator motor; both the driver's side window regulator relay and the passenger side window regulator relay consist of two pentagonal relays; and at least four pins of the main window regulator switch are grounded.

[0018] Optionally, the device further includes a secondary window regulator switch; the secondary window regulator switch is disposed between the primary window regulator switch and the passenger side window relay; the secondary window regulator switch is used to control the raising and lowering of the passenger side window; the primary window regulator switch is also used to control the on / off state of the secondary window regulator switch.

[0019] Optionally, the main window regulator includes a driver's side switch; the driver's side switch is connected to the driver's side window relay and is used to control the raising and lowering of the driver's side window.

[0020] Optionally, the main window regulator also includes a passenger-side switch; the passenger-side switch is connected to the passenger-side window relay and is used to control the raising and lowering of the passenger-side window.

[0021] Optionally, the main lifter also includes a secondary lifter switch control switch; the secondary lifter switch control switch is connected to the secondary lifter switch, and the secondary lifter switch control switch is used to control the on / off state of the secondary lifter switch.

[0022] Specifically, taking the raising and lowering process of the driver's side and passenger side windows as an example, the above-mentioned window regulator motor control device is explained. When the driver wants to raise or lower the driver's side window, they can control the small switch on the driver's side to close, thereby energizing the driver's side window regulator motor through the driver's side window relay, thus raising or lowering the driver's side window. When the driver wants to raise or lower the passenger side window, they can control the small switch on the passenger side to close, thereby energizing the passenger side window regulator motor through the passenger side window relay, thus raising or lowering the passenger side window. When the passenger wants to raise or lower the passenger side window, they can control the passenger side window regulator switch to close, thereby energizing the passenger side window regulator motor through the passenger side window relay, thus raising or lowering the passenger side window. It should be noted that the passenger side window regulator switch is also connected to the passenger side window regulator switch control switch, which controls the on / off state of the passenger side window regulator switch. When the passenger side window regulator switch control switch is off, even if the passenger closes the passenger side window regulator switch, the entire circuit remains open, and the passenger side window cannot be raised or lowered. Furthermore, Figure 1 Pins 1, 2, 3, and 8 are all grounded. Grounding multiple pins can shunt the negative current and prevent excessive current.

[0023] The window regulator motor control device in the above embodiment includes: a main window regulator switch, which connects the driver's side window regulator motor and the passenger side window regulator motor, and is used to control the raising and lowering of the driver's side window and the passenger side window; a driver's side window regulator relay is provided between the main window regulator switch and the driver's side window regulator motor, and a passenger side window regulator relay is provided between the main window regulator switch and the passenger side window regulator motor; both the driver's side window regulator relay and the passenger side window regulator relay consist of two pentagonal relays; and at least four pins of the main window regulator switch are grounded. Because the above device includes driver's side window regulator relays and passenger side window regulator relays, it can prevent large currents from flowing through the switch, thus avoiding damage to the switch. Furthermore, the increased number of grounding pins on the main window regulator switch achieves negative current shunting, preventing excessive current and further preventing the switch from burning out due to excessive current.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0025] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent.
