[0022] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Please refer to Figure 1 — Figure 4 This embodiment provides an opening and closing device for a car sliding outward swing door. Includes: an opening motor, an electromagnetic traction assembly, a motor opening and closing assembly, and an elastic reset assembly disposed inside the opening motor housing; The motor can be opened electrically or manually. The motor opening and closing assembly is used to control whether the motor is in an electrically opened or manually opened state. The electromagnetic traction component is configured to generate a magnetic attraction force on the motor opening and closing component, so that the opening motor is in an electrically open state. The elastic reset component is connected to the motor opening and closing component, and the elastic reset component is used to give the motor opening and closing component a tendency to move toward the position of being in the manual open state.

[0024] This invention provides an opening and closing device for a car sliding outward swing door. Through the coordinated action of an electromagnetic traction component, a motor opening and closing component, and an elastic reset component, it can automatically switch between the electric opening mode and the manual opening mode of the opening motor. By eliminating the original emergency handle mechanism, reducing the number of components, and lowering costs, it can also improve the convenience of assembly and after-sales maintenance. Moreover, after the vehicle is powered off, the opening motor can automatically switch to the manual opening mode, eliminating the need to operate the emergency handle to switch the opening mode. The door can be opened directly by hand, improving operational convenience.

[0025] The motor opening and closing assembly includes two slide rails 2 fixed inside the motor housing, and the two slide rails 2 are symmetrically distributed vertically. A traction slider 3 is slidably mounted between the two slide rails 2. A traction arm 4 is fixedly provided on one end face of the traction slider 3 and is vertically distributed. A trigger is provided between the other end of the traction arm 4 and the switch for opening the motor. By restricting the traction slider 3 with two vertically distributed slide rails 2, the stability of the traction slider 3 in lateral sliding can be ensured. At the same time, lubricating grease should be applied to the connection between the traction slider 3 and the slide rail 2 to reduce the resistance of the traction slider 3 sliding between the two slide rails 2. When the traction slider 3 slides to the left, the switch to start the motor will be turned on through the trigger.

[0026] The triggering element includes a conversion handle 7 located on the outside of the traction arm 4. A straight groove is provided inside the conversion handle 7. A conversion slider 5 is fixedly provided at the end of the traction arm 4 away from the traction slider 3, and the conversion slider 5 is slidably embedded in the straight groove. The straight groove and the conversion handle 7 are parallel to each other. The bottom of the conversion handle 7 is rotatably assembled in the opening motor housing through a connecting shaft. The motor start switch was not activated before the position of the change handle 7 changed, so the motor was in the off state. After the position of the change handle 7 changes, it has triggered the motor switch, and the motor is now in the on state. When the traction slider 3 slides to the left, the straight groove and the conversion slider 5 work together to pull the conversion handle 7, causing it to swing. At the same time, the return spring 6 is stretched and unfolded. After the position of the conversion handle 7 changes, the switch to start the motor will be activated, putting the motor in the start state. When the traction slider 3 and the conversion handle 7 return to their original positions under the elastic pull of the return spring 6, the switch to start the motor will be closed again, putting the motor in the off state.

[0027] The elastic reset assembly includes a mounting hole on the upper end face of the shift handle 7, and a reset spring 6 is fixedly disposed between the mounting hole and the inside of the motor housing. The reset spring 6 is located on the side of the shift handle 7 away from the traction slider 3. The mounting hole facilitates the installation of the return spring 6 between the change handle 7 and the motor housing.

[0028] The electromagnetic traction assembly includes an electromagnet 1 fixed inside the housing of the opening motor, with the magnetic poles of the electromagnet 1 facing the traction slider 3. The traction slider 3 is made of magnetic material. A power supply with an independent switch is also provided on the outside of the electromagnet 1. The power supply is used to provide electrical energy to the electromagnet 1. By controlling the power supply, the electromagnet 1 can be connected to or disconnected from the power supply, thereby making the electromagnet 1 magnetic or non-magnetic. When the electromagnet 1 is energized, it can magnetically attract the traction slider 3, causing the traction slider 3 to move to the left. When the magnetism of the electromagnet 1 disappears, the traction slider 3 can be reset and moved by the reaction force generated by the return spring 6.

[0029] The traction slider 3 is made of carbon alloy. Carbon alloy materials, such as iron and iron alloys, can enable the traction slider 3 to be effectively attracted by the electromagnet 1 when it is energized.

[0030] The traction slider 3 is a magnetic block, and the electromagnet 1 has opposite magnetic poles to the opposite end face of the traction slider 3 when it is energized. If the traction slider 3 is itself a magnetic block and possesses magnetism, when the electromagnet 1 is energized, the traction slider 3 can be more easily attracted by the electromagnet 1 through the principle of opposite phases attracting each other.

[0031] Electromagnet 1 is located on the side of the traction slider 3 away from the return spring 6; When the electromagnet 1 is energized, it will attract the traction slider 3 to move to the left and trigger the switching handle 7, causing the switching handle 7 to change position.

[0032] When the electromagnet 1 is de-energized, the magnetic attraction between the electromagnet 1 and the traction slider 3 is less than the elastic tension applied by the return spring 6 to the switching handle 7. Ensure that the reset spring 6 can effectively reset the change handle 7 after the electromagnet 1 loses its magnetism.

[0033] When electromagnet 1 is energized, the magnetic attraction between electromagnet 1 and traction slider 3 is greater than the elastic pulling force applied to the switching handle 7 by the return spring 6. Ensure that when electromagnet 1 is energized, the traction slider 3 can move stably toward electromagnet 1 through magnetic attraction.

[0034] Working principle: After the vehicle is powered on, the coil of electromagnet 1 can form an electromagnetic field under the current provided by the power supply, so that electromagnet 1 has magnetic attraction ability. Electromagnet 1 magnetically attracts the traction slider 3. When the traction slider 3 moves in the direction of electromagnet 1, the position of the conversion handle 7 can be changed by the action of the traction arm 4, the conversion slider 5 and the straight groove, and the return spring 6 is stretched, thereby realizing the switching of the motor from manual opening mode to electric opening mode. After the vehicle is powered off, the power supply no longer provides a stable current to the electromagnet 1. At this time, the electromagnet 1 cannot generate magnetism, so it cannot magnetically attract the traction slider 3. At this time, the return spring 6 generates a reaction force, which can pull the conversion handle 7. At the same time, through the cooperation of the traction arm 4, the conversion slider 5 and the straight groove, the conversion handle 7 and the traction slider 3 are reset and moved, so that the motor can be switched from electric opening mode to manual opening mode.

[0035] The above scheme enables the motor to be turned on or off with the power supply of the vehicle. Under the traction of the electromagnet 1 and the return spring 6, the switching handle 7 can be rotated to switch between electric and manual opening modes.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
