[0022] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0023] Please refer to Figure 1-Figure 5 The present invention proposes an inductive electric door handle, comprising: a base 1, a handle 2, a drive assembly 3, a key identification system 4, and a distance sensor 5. The base 1 is provided with a accommodating cavity 10; the handle 2 is installed in the accommodating cavity 10 and is hinged to the base 1. Further, the handle 2 has a first state and a second state. The first state is that the handle 2 is inclined relative to the base 1, and the second state is that the handle 2 is parallel to the base 1.

[0024] Specifically, the handle 2 includes a first end 20 and a second end 21; the key recognition system 4 is used to identify the car key within the sensing distance and unlock the inductive electric door handle after successful recognition. When the inductive electric door handle is unlocked, once the distance sensor 5 senses a human hand within a preset distance, the driving component 3 drives the first end 20 to sink into the accommodating cavity 10 while the second end 21 rises from the accommodating cavity 10. At this time, the handle 2 is tilted relative to the base 1, and the handle 2 is in a first state.

[0025] Furthermore, the key recognition system 4 includes a signal receiving unit 40 and an unlocking unit 41 arranged in the vehicle, and a signal transmitting unit 42 arranged in the car key. When the car key enters the sensing distance, the signal transmitting unit 42 sends a key approaching signal to the signal receiving unit 40, and then the unlocking unit 41 unlocks the induction electric door handle.

[0026] In this embodiment, when the user enters the sensing distance with the car key, the inductive electric door handle is already in the unlocked state. Specifically, the signal transmitting unit 42 sends the key approaching signal to the signal receiving unit 40, and then the unlocking unit 41 unlocks the inductive electric door handle. Although the inductive electric door handle is already in the unlocked state at this time, the car door is still in the closed state, and then when a human body reaches out to approach the door handle, the distance sensor 5 senses the human hand within the preset distance, and the driving component 3 drives the first end 20 to sink into the accommodating cavity 10 while the second end 21 is lifted up from the accommodating cavity 10. At this time, the user can open the car door by pulling the lifted second end 21.

[0027] In the door handle of this type of car in the prior art, the user needs to press the first end 20 with one hand to make the first end 20 sink into the accommodating cavity 10, thereby making the second end 21 tilt up, so that the user can hold it with the other hand to open the car door.

[0028] In this embodiment, compared with the prior art, the inductive electric door handle of the present invention can sense human hands within a certain distance, and automatically lift one end of the handle 2 to facilitate the user to pull the door handle, thereby opening the car door. It has the characteristics of one-handed operation and freeing both hands. At the same time, it has the advantages of easy and quick use, good effect and high safety.

[0029] Furthermore, when the induction electric door handle is locked, the first end 20 and the second end 21 are flushly accommodated in the accommodating cavity 10. At this time, the handle 2 is parallel to the base 1, and the handle 2 is in the second state. The induction electric door handle does not protrude relative to the base 1, which has the effect of hiding the door handle, making the car body more simple and beautiful.

[0030] Furthermore, the driving assembly 3 includes a driving motor 30 and a pull wire 31 connected to the driving motor 30 .

[0031] Furthermore, the pull wire 31 includes a wire sleeve 310 and a pull core 311 disposed in the wire sleeve 310. The drive motor 30 can rotate forward or reverse, thereby tightening the pull core 311 or loosening the pull core 311. When the drive motor 30 tightens the pull core 311, the handle 2 is in a first state; when the drive motor 30 loosens the pull core 311, the handle 2 is in a second state.

[0032] Furthermore, a fixing frame 11 is mounted on the base 1, the end of the wire sleeve 310 away from the driving motor 30 is fixedly connected to the fixing frame 11, and the pull core 311 passes through the fixing frame 11 and is fixedly connected to the first end 20. A return spring is also arranged in series on the pull core 311, and the return spring is located between the fixing frame 11 and the first end 20.

[0033] Furthermore, a mounting shell 12 is fixedly provided on the base 1, and the distance sensor 5 is fixedly mounted in the mounting shell 12. The mounting shell 12 is used to protect the distance sensor 5, and the distance sensor 5 is a capacitive distance sensor 5.

[0034] Furthermore, a shielding cover 13 is included, and the shielding cover 13 is arranged on the outer periphery of the installation shell 12. The shielding cover 13 prevents external signals from interfering with the sensing signal of the distance sensor 5.

[0035] Furthermore, the handle 2 is provided with a wing portion 22 protruding relative to its two side portions, and the wing portion 22 is provided with a through hole 220. The base 1 is provided with a mounting hole 14 on both sides of the accommodating cavity 10, which is connected to the accommodating cavity 10, and the rotating shaft 15 passes through the mounting hole 14 and the through hole 220 in sequence.

[0036] In this embodiment, the handle 2 and the base 1 are hingedly connected by the cooperation among the rotating shaft 15 , the mounting hole 14 , and the through hole 220 , so that the handle 2 can rotate relative to the base 1 .

[0037] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
