Description

Technical Field

[0001] The utility model relates to the field of vehicle door switch structures, in particular to a non-self-locking vehicle door switch structure. Background Art

[0002] As people's quality of life improves, their requirements for travel convenience and comfort are also increasing. The automation and intelligence of automobiles are also developing rapidly. Automatic opening and closing of car doors has gradually become a convenient function of current cars. Although opening and closing doors is an inevitable action in daily use of cars, it may be inconvenient to open and close doors due to various reasons in daily use.

[0003] If the motor of a traditional door switch structure is not powered, opening and closing the door may cause the structure to lock automatically, making it impossible to open and close the door normally. In this case, if the electronic system fails, the door may become stuck, preventing passengers from escaping safely. Utility Model Content

[0004] In response to the deficiencies of the prior art, the present invention provides a non-self-locking door switch structure, which solves the problem that when the motor of the door switch structure is not powered, opening and closing the door may cause the structure to lock automatically, making it impossible to open and close the door normally.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a non-self-locking car door switch structure, including a non-self-locking reduction gearbox housing, a transmission shaft is rotatably connected to the middle of the lower surface of the non-self-locking reduction gearbox housing, the lower end of the transmission shaft is fixedly connected to the upper surface of the rotating base, the upper end of the rotating base is rotatably connected to the lower surface of the non-self-locking reduction gearbox housing, the lower surface of the rotating base is fixedly connected to a connecting column, the lower end of the connecting column is fixedly connected to two connecting teeth, a rotating swing arm is provided below the connecting column, a connecting slot is opened on the rotating swing arm at the position corresponding to the two connecting teeth, the connecting tooth is engaged with the rotating swing arm through the connecting slot, and a transmission gear is fixedly connected to the outer side of the middle part of the transmission shaft.

[0006] Preferably, a drive shaft is provided on the outside of the transmission gear, a threaded ring is provided on the outer surface of one end of the drive shaft close to the transmission gear, a motor is provided on the outside of the non-self-locking reduction gearbox housing, and the output end of the motor is rotatably connected to the drive shaft.

[0007] Preferably, a main gear is fixedly connected to the outer side of the lower end of the transmission shaft, and three sub-gears are distributed around the outer side of the main gear. The inner sides of the three sub-gears are meshed and connected to the outer side of the main gear, and the outer sides of the three sub-gears are meshed and connected to the reduction gear.

[0008] Preferably, four grooves are distributed in an annular shape on the inner side of the rotating base.

[0009] Preferably, four protrusions are arranged in an annular shape on the outer side of the reduction gear.

[0010] Preferably, the upper surface of one end of the rotating swing arm away from the connecting column is rotatably connected to a universal driving connecting rod.

[0011] Beneficial effects

[0012] The present invention provides a non-self-locking door switch structure. Compared with the prior art, it has the following advantages:

[0013] 1. In the utility model, through the provided rotating swing arm, during the process of opening and closing the vehicle door, the output end of the driving motor drives the driving shaft to rotate. After the driving shaft rotates, the threaded ring on the outer side of the driving shaft meshes with the transmission gear below the non-self-locking reduction gear case, thereby rotating the transmission gear together with the transmission shaft in the middle. While the transmission shaft rotates, the main gear on the outer side of the lower end of the driving shaft meshes with the three sub-gears in succession, and then the three sub-gears mesh with the reduction gear to rotate the reduction gear. When the reduction gear rotates, the rotating base connected to it rotates accordingly, and the rotating swing arm connected to the bottom of the rotating base by the connecting column swings accordingly, thereby being able to pull the vehicle door to realize the opening and closing process through the universal drive connecting rod. Compared with the traditional vehicle door switch structure, this structure will not lock itself. Even when the motor is not powered, the opening and closing of the vehicle door can drive the rotating swing arm to rotate, ensuring that the vehicle door can still be opened and closed normally when the electronic system fails, thereby improving the emergency reliability of the vehicle.

[0014] 2. In the present invention, by setting a reduction gear, since the diameter of the reduction gear is larger than that of the transmission gear, the rotation speed of the rotating base can be reduced. After the rotation speed of the rotating base is reduced, the output end speed of the motor drive is prevented from being too high, which causes the door opening and closing speed to be too fast, so that the door opening and closing speed can be controlled more accurately.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 4 , the utility model provides two technical solutions, specifically including the following embodiments:

[0023] Example 1:

[0024] A non-self-locking door switch structure includes a non-self-locking reduction gearbox housing 1, a transmission shaft 6 is rotatably connected to the middle of the lower surface of the non-self-locking reduction gearbox housing 1, the lower end of the transmission shaft 6 is fixedly connected to the upper surface of a rotating base 10, the upper end of the rotating base 10 is rotatably connected to the lower surface of the non-self-locking reduction gearbox housing 1, a connecting column 11 is fixedly connected to the lower surface of the rotating base 10, and two connecting teeth 12 are fixedly connected to the lower end of the connecting column 11. A rotating swing arm 13 is provided below the connecting column 11, and a connecting slot 15 is provided at the position of the rotating swing arm 13 corresponding to the two connecting teeth 12. The connecting teeth 12 are engaged with the rotating swing arm 13 through the connecting slot 15. A transmission gear 5 is fixedly connected to the outer side of the middle part of the transmission shaft 6, and a universal drive link 14 is rotatably connected to the upper surface of the end of the rotating swing arm 13 away from the connecting column 11, and the end of the universal drive link 14 away from the rotating swing arm 13 is used to be connected to the car door.

[0025] During operation, in the process of opening and closing the car door, the output end is driven by the motor 2 to rotate the drive shaft 3. After the drive shaft 3 rotates, the threaded ring 4 on its outer side engages with the transmission gear 5 under the non-self-locking reduction gear case 1, thereby rotating the transmission gear 5 together with the transmission shaft 6 in the middle. While the transmission shaft 6 rotates, the main gear 8 on the outer side of its lower end engages with the three sub-gears 9 in succession, and then the three sub-gears 9 engage with the reduction gear 7, causing the reduction gear 7 to rotate. While the reduction gear 7 rotates, the rotating base 10 engaged with it rotates accordingly, and the rotating swing arm 13 engaged with the connecting column 11 under the rotating base 10 swings accordingly, and then the car door can be pulled by the universal drive link 14 to realize the opening and closing process. Compared with the traditional car door switch structure, this structure will not lock itself. Even when the motor 2 is not powered, opening and closing the car door can drive the rotating swing arm 13 to rotate, ensuring that the car door can still be opened and closed normally when the electronic system fails, thereby improving the emergency reliability of the vehicle.

[0026] Example 2:

[0027] On the basis of Example 1, a drive shaft 3 is provided on the outside of the transmission gear 5, and a threaded ring 4 is provided on the outer surface of the end of the drive shaft 3 close to the transmission gear 5. A motor 2 is provided on the outside of the non-self-locking reduction gear housing 1, and the output end of the motor 2 is rotatably connected to the drive shaft 3. A main gear 8 is fixedly connected to the outside of the lower end of the transmission shaft 6, and three sub-gears 9 are distributed around the outside of the main gear 8. The inner sides of the three sub-gears 9 are all meshed and connected to the outer side of the main gear 8, and the outer sides of the three sub-gears 9 are meshed and connected to the reduction gear 7. The size of the reduction gear 7 is larger than the transmission gear 5. Four grooves 16 are distributed in an annular manner on the inner side of the rotating base 10, and four protrusions are provided in an annular manner on the outer side of the reduction gear 7. Since the diameter of the reduction gear 7 is larger than the transmission gear 5, the rotation speed of the rotating base 10 can be reduced. After the rotation speed of the rotating base 10 is reduced, the output end speed driven by the motor 2 is avoided from being too high, which causes the door opening and closing speed to be too fast, so that the door opening and closing speed can be more accurately controlled.

[0028] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the application should be included in the scope of protection of the present application.
