[0006] Furthermore, the driving gear set includes a main transmission gear and a sub transmission gear that mesh with each other. When the electric switch button is pressed downward, the main transmission gear is driven to rotate, and the main transmission gear drives the sub transmission gear to rotate to move the lock hook on the switch bracket.

[0007] Furthermore, a tooth surface meshing with the main transmission gear is provided on the side wall of the electric switch button.

[0008] Furthermore, the lock hook is provided with a rack meshing with the transmission pinion.

[0009] Furthermore, a return spring is arranged in the switch bracket, and two ends of the return spring are respectively connected to the switch bracket and the electric switch button.

[0010] Furthermore, the switch bracket is provided with a magnetic attraction system for fixing the electric switch button on the switch bracket.

[0011] In summary, the present utility model includes at least one of the following beneficial effects: By combining an electric door switch and a mechanical emergency switch, a single part realizes two door opening methods, arranging the mechanical emergency switch and the electric door switch at the same position. When the vehicle loses power under emergency conditions, rescue personnel outside the vehicle can quickly access the mechanical emergency switch and open the door. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following specific examples illustrate the embodiments of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model.

[0018] The following further elaborates on the present utility model Figures 1-3 in conjunction with the attached drawings.

[0019] An embodiment of the present utility model discloses a multi-functional door switch. Refer to Figures 1-3The multifunctional door switch comprises a switch bracket 1, an electric switch button 2 arranged on the switch bracket 1, a driving gear set 3 arranged in the switch bracket 1 and a lock hook 4 slidably arranged on the switch bracket 1, the electric switch button 2 is connected to the lock hook 4 through the driving gear set 3, the electric switch button 2 uses a micro switch and a circuit board to control the electric opening of the door, and the door is opened by lightly pressing the electric switch button 2. When the door needs to be opened mechanically, the electric switch button 2 is pressed downward with force to move the lock hook 4 on the switch bracket 1. When the door needs to be opened, the electric switch button 2 is pressed downward, and the electric switch button 2 moves downward to move the lock hook 4 through the driving gear set 3 to open the door. Combined with the electric door switch and the mechanical emergency switch, a single part realizes two door opening methods, so that the mechanical emergency switch and the electric door switch are arranged at the same position. When the vehicle loses power in an emergency condition, rescue personnel outside the vehicle can quickly access the mechanical emergency switch and open the door.

[0020] In this embodiment, the driving gear set 3 includes a main transmission gear 31 and a transmission sub-gear 32 that mesh with each other. Two transmission sub-gears 32 are provided. When the electric switch button 2 is pressed downward, the main transmission gear 31 is driven to rotate. The main transmission gear 31 drives the transmission sub-gear 32 to rotate to move the lock hook 4 on the switch bracket 1. Pressing the electric switch button 2 downward drives the main transmission gear 31 and the transmission sub-gear 32 to rotate, so that the lock hook 4 can move into the switch bracket 1 to open the car door.

[0021] In this embodiment, a tooth surface 21 meshing with the main transmission gear 31 is provided on the side wall of the electric switch button 2 .

[0022] In this embodiment, a rack 41 meshing with the transmission pinion 32 is disposed on the lock hook 4 .

[0023] In this embodiment, a return spring 11 is provided in the switch bracket 1, and the two ends of the return spring 11 are respectively connected to the switch bracket 1 and the electric switch button 2. When the electric switch button 2 is pressed downward, the electric switch button 2 squeezes the return spring 11, so that the return spring 11 is in a compressed state. After the mechanical door opening is completed, the electric switch button 2 is released, and the electric switch button 2 is reset under the action of the return spring 11.

[0024] In this embodiment, the switch bracket 1 is provided with a magnetic system 5 for fixing the electric switch button 2 on the switch bracket 1. When the electric switch button 2 is pressed downward, when the external pressing force is greater than the attraction of the magnetic system to the electric switch button 2, the electric switch button 2 is displaced, driving the drive gear set 3 to move, and the mechanical opening of the door is achieved through the drive gear set 3.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
