[0022] FIG. 1 shows a schematic diagram of the circuit structure of the sliding door electronic control mechanism according to the present invention. The sliding door electronic control mechanism is provided in a vehicle body electric module 1 and a sliding door electric module 2 in a vehicle, and a switch 3 and a sliding door hinge 4 are provided at a contact position between the vehicle body and the sliding door, so as to realize a connection without a wire harness between the sliding door electric module 2 and the vehicle body electric module 1. By providing related modules such as a backup power supply 21 and a controller 22 in the sliding door electric module 2, normal operation is maintained when the sliding door is open. As can be seen from the above content, the sliding door electronic control mechanism according to the present invention can include a switch 3, a backup power supply 21, and a controller 22.

[0023] As shown in FIG. 1, the switch 3 is provided at a position where the vehicle sliding door contacts the vehicle body. The installation position of the switch 3 may not be limited. In an embodiment of the present invention, the installation position of the switch 3 is on a guide rail where the sliding door contacts the vehicle body. The switch 3 is a contact type switch, which is divided into two parts. One part is provided on the sliding door, and the other part is provided on the vehicle body. When the sliding door is closed, one part of the switch 3 on the sliding door contacts the other part on the vehicle body, and cooperates with the circuit of the sliding door hinge 4 that always maintains the connection state between the vehicle body and the sliding door, to connect the circuits of the vehicle body electric module 1 and the sliding door electric module 2. Also, when the sliding door is open, the contact between one part of the switch 3 on the sliding door and the other part on the vehicle body is released, to disconnect the circuits of the vehicle body electric module 1 and the sliding door electric module 2.

[0024] As shown in FIG. 1, the controller 22 is provided in the slide door electric module 2 within the slide door. The controller 22 is electrically connected to each component that needs to be controlled for the slide door, such as components like the electric door lock 23, the glass motor 24, and the glass window switch, and is further electrically connected to the switch 3 through a circuit. A wireless communication module is further provided in the controller 22. It is not only wired-connected to the vehicle body controller 12 in the vehicle body electric module 1 through a circuit, but also can communicate with the vehicle body controller 12 through a wireless network, realizing that the slide door receives control support from the vehicle body controller 12 in a wireless state, and realizing normal operations and controls of operations such as locking the door and opening the window.

[0025] As shown in FIG. 1, the backup power supply 21 is provided in the slide door electric module 2 within the slide door. It is electrically connected to each electrical component of the slide door through a circuit, such as components like the electric door lock 23, the glass motor 24, and the glass window switch, and is further electrically connected to the switch 3 through a circuit. With the above installation method, the backup power supply 21 can provide power support to each electrical component in the slide door electric module 2 and can be connected to the main power supply through the switch 3 for charging.

[0026] When the sliding door is closed, the circuit of the sliding door electric module 2 is connected to the circuit of the vehicle body electric module 1 by the switch 3. The main power supply 11 of the vehicle and the vehicle body controller 12 are connected to each electrical component of the sliding door and each component that needs to be controlled by the switch 3. The main power supply 11 provides power support for each electrical component of the sliding door, and the vehicle body controller 12 provides control support for each component that needs to be controlled of the sliding door. When the sliding door is open, the connection between the circuit of the vehicle body electric module 1 and the circuit of the sliding door electric module 2 is disconnected. The backup power supply 21 in the sliding door electric module 2 provides power support for each electrical component of the sliding door. The backup power supply 21 and the sliding door hinge 4 respectively provide power supply and auxiliary grounding for the sliding door electric module 2. The controller 22 controls the operation of each component that needs to be controlled of the sliding door. For example, it controls the glass motor 24 to realize the raising and lowering of the door window glass, controls the switch of the electric door lock 23, etc., and communicates with the vehicle body controller 12 in a timely manner through the built-in wireless communication module, and feeds back and displays the opening and closing state of the sliding door to the vehicle combination meter panel by the vehicle body controller 12 to inform the driver of the open state of the sliding door and avoid the occurrence of the problem of forgetting to close the door. Also, when the controller 22 receives the sleep signal transmitted from the vehicle body controller 12, it synchronously enters the sleep state.

[0027] As shown in FIG. 1, in an embodiment of the present invention, the switch 3 is a contact type switch including a first contact 31 and a second contact 32. The first contact 31 is provided at a position where the vehicle body and the sliding door contact, for example, on the guide rail where the sliding door and the vehicle body contact. The second contact 32 is provided on the sliding door corresponding to the position of the first contact 31 on the vehicle body. The first contact 31 is electrically connected to the main power supply 11 and the vehicle body controller 12 of the vehicle body electric module 1 on the vehicle body by a circuit, and the second contact 32 is electrically connected to each component such as the backup power supply 21, the controller 22, the electric door lock 23, and the glass motor 24 of the sliding door electric module 2 in the sliding door by a circuit.

[0028] In addition, in this embodiment, when the sliding door is closed, the first contact 31 and the second contact 32 of the switch 3 are in contact with each other, and the contact-type switch is turned on. The circuit between the vehicle body electric module 1 and the sliding door electric module 2 is connected by the cooperation of the switch 3 and the sliding door hinge 4. When the sliding door is open, the contact between the first contact 31 and the second contact 32 of the switch 3 is released, the contact-type switch is closed, and the circuit between the vehicle body electric module 1 and the sliding door electric module 2 is disconnected.

[0029] As shown in FIG. 1, in one embodiment of the present invention, an electric door lock 23 is further provided on the sliding door. The controller 22 is electrically connected to the electric door lock 23. The electric door lock 23 transmits an unlock signal and a lock signal to the controller 22 when the sliding door is opened and closed. The controller 22 detects whether the sliding door is in an open state or a closed state by receiving the unlock signal and the lock signal transmitted from the electric door lock 23.

[0030] As shown in FIG. 1, in one embodiment of the present invention, an electric quantity detector 25 is further integrated in the sliding door electric module 2 of the sliding door. The electric quantity detector 25 is electrically connected to the backup power supply 21 and the controller 22, monitors the electric quantity of the backup power supply 21, and when it detects that the remaining electric quantity of the backup power supply 21 is lower than the set electric quantity value, transmits a signal of insufficient electric quantity, is relayed through the controller 22, and communicates with the vehicle body controller 12, or directly transmits to the vehicle body controller 12 through the connected circuit, and finally is displayed by the combination meter panel, and alarms with a buzzer. When the sliding door is in the closed state, the main power supply 11 in the vehicle body electric module 1 charges the backup power supply 11 through the circuit connected by the switch 3. When the sliding door is in the open state, first, the user needs to close the sliding door, and then the main power supply 11 in the vehicle body electric module 1 charges the backup power supply 11.

[0031] The slide door electronic control method according to the present invention is a step of providing a switch 3 at a position where the slide door of the vehicle contacts the vehicle body, connecting the circuit between the slide door electric module 2 on the slide door and the vehicle body electric module 1 on the vehicle body by turning off the switch when the slide door is closed, and when the slide door is open, releasing the contact between the part of the switch 3 on the slide door and the part on the vehicle body to disconnect the circuit between the slide door electric module 2 on the slide door and the vehicle body electric module 1 on the vehicle body; a step of providing a controller 22 on the slide door and electrically connecting the controller 22 to each component that needs to be controlled by the slide door electric module 2 on the slide door; a step of providing a backup power supply 21 on the slide door and electrically connecting the backup power supply 21 to each electrical component of the slide door electric module 2 on the slide door; when the slide door is open, the backup power supply 21 and the controller 22 respectively provide power support and control support to each component of the slide door electric module 2 on the slide door, and the controller 22 further communicates with the vehicle body controller through a wireless network to receive a control signal transmitted from the vehicle body controller.
