DETAILED DESCRIPTION

The following describes the implementation of the disclosure through specific embodiments, and those skilled in the art can easily understand other advantages and effects of the disclosure from the content disclosed in this specification. The disclosure may also be implemented or applied through other different specific embodiments. Various details in this specification may also be modified or changed based on different viewpoints and applications without departing the subject-matter of the appending claims. It should be noted that following embodiments and features in the embodiments may be combined with each other under a condition of no conflict. It should also be understood that terms used in the embodiments of the disclosure are used to describe specific embodiments, rather than to limit a protection scope of the disclosure. In the following embodiments, test methods without specific conditions are usually in accordance with conventional conditions or in accordance with conditions suggested by various manufacturers.
Please refer to FIG. 1. The disclosure provides an inner handle for an automobile, which may be arranged on a door body to drive the door body to be opened and closed. A locking structure 10 is usually arranged between the door body and the vehicle body, and a connection between the vehicle body and the door body is realized through the locking structure 10. Therefore, an unlocking and locking of the locking structure 10 may be adjusted by driving the inner handle for automobiles, thereby driving an opening and closing of the door body.
Please refer to FIG. 1. In some embodiments, a specific structure of the locking structure 10 may not be limited, for example, the locking structure 10 may include a locking cylinder and a locking groove. A locking of the locking structure 10 is realized by clamping the locking cylinder with the locking groove, and an unlocking of the locking structure 10 is realized by separating the locking cylinder from the locking groove. And an unlocking method of the locking structure 10 is not limited, for example, the locking structure 10 may be unlocked by a mechanical module, or the locking structure 10 may be unlocked by an electronic module. An unlocking of the mechanical module means that during an unlocking process of the locking structure 10, the locking structure 10 is driven by a mechanical mechanism of the mechanical module to realize the unlocking of the locking structure 10. Therefore, during an unlocking process of the mechanical module, there is no additional power input. Further, an unlocking of the electronic module means that during the unlocking process of the locking structure 10, the locking structure 10 is driven by a circuit control of the electronic module to realize the unlocking of the locking structure 10. Therefore, during an unlocking process of the electronic module, there is no input from the mechanical module. By setting the locking structure 10 with multiple unlocking methods such as mechanical modules and electronic modules, an actual use effect of the locking structure 10 may be improved.
In some embodiments, the inner handle for automobile may be connected with the mechanical module and the electronic module at the same time. Therefore, by driving the inner handle for automobile, the unlocking and locking of the locking structure 10 can be adjusted, thereby driving the opening and closing of the door body.
Please refer to FIG. 2. In some embodiments, the inner handle for automobile may include a handle 1, a base 2 and a reset assembly 3. The base 2 is connected with the door body, and the handle 1 is rotatably connected with the base 2. A pin shaft 301 may be connected with the base 2, and a through hole may be arranged on the handle 1. Therefore, the handle 1 rotates relative to the pin shaft 301 by rotatably connecting the through hole on the handle 1 with the pin shaft 301. Therefore, the handle 1 may rotate relative to the pin shaft 301 to realize a rotational connection between the handle 1 and the base 2. The reset assembly 3 is located between the handle 1 and the base 2, so when the handle 1 rotates relative to the base 2 by a certain angle, the reset assembly 3 is configured to reset the handle 1. Therefore, after the door body is opened, the handle 1 may be quickly reset through the reset assembly 3. A specific structure of the reset assembly 3 may not be limited. For example, in an embodiment, the reset assembly 3 may include a torsion spring 302. Specifically, the torsion spring 302 is connected between the base 2 and the handle 1, so that the handle 1 may be reset in time after rotating.
Please refer to FIG. 3 through FIG. 5. In some embodiments, the handle 1 is connected with the electronic module, and the electronic module may include a switch 4, a motor and a first driving component 6. The switch 4 is connected with a control circuit of the motor, so the motor may be driven to rotate by triggering the switch 4. A specific structure of the switch 4 may not be limited. In one embodiment, the switch 4 may be a micro switch. Therefore, through the micro switch, a triggering precision of the switch 4 may be improved, so as to improve an actual use effect of the electronic module. Further, an output end of the motor is connected with the locking cylinder, so during a rotation of the motor, the locking cylinder may be driven to be separated from the locking groove. As long as the locking cylinder may be driven to move by the motor, a specific connection between the output end of the motor and the locking cylinder may not be limited. For example, in some embodiments, a rack may be connected to the locking cylinder, a gear is connected to the output end of the motor, and the gear and the rack are in a meshing connection. Therefore, through the rotation of the motor, the gear drives the rack to move, thereby driving the locking cylinder to move. Specifically, the first driving component 6 is connected with the handle 1, and the first driving component 6 and the handle 1 are fixedly connected with each other, so the first driving component 6 may rotate synchronously with the handle 1. Therefore, when the first driving component 6 rotates, the switch 4 is triggered to drive the motor to rotate, thereby driving the lock cylinder to move. In order to improve a practical use effect of the first driving component 6, in one embodiment, the first driving component 6 is provided with a notch 602 and a protrusion 601. When the handle 1 is in an non-rotating state, a contacting point 5 of the switch 4 is located in the notch 602, and there may be a certain gap between the first driving component 6 and the contacting point 5. Therefore, by setting the gap between the first driving component 6 and the contacting point 5, it is possible to avoid touching the micro switch by mistake, so as to improve the actual use effect of the electronic module. When the handle 1 rotates at a certain angle, the protrusion 601 is in contact with the contacting point 5 of the switch 4 to trigger the switch 4. Specifically, when the protrusion 601 and the switch 4 are triggered, a rotation angle of the handle 1 may not be limited. For example, in one embodiment, when the protrusion 601 and the switch 4 are triggered, the rotation angle of the handle 1 may be from 10 degrees to 20 degrees.
Please refer to FIG. 6 and FIG. 7. In some embodiments, the handle 1 is connected with the mechanical module, and the mechanical module may include a pulling wire 7 and a second driving component 8. Wherein, one end of the pulling wire 7 is connected with the locking cylinder, and the locking cylinder may be driven to be separated from the locking groove by pulling the pulling wire 7. The other end of the pulling wire 7 is connected with the second driving component 8, so the pulling wire 7 may be pulled by driving the second driving component 8. Specifically, the second driving component 8 is connected on the handle 1 and is fixedly connected with the handle 1. During the rotation of the handle 1, the second driving component 8 may rotate synchronously with the handle 1. Therefore, when the handle 1 rotates at a certain angle, the second driving component 8 pulls the pulling wire 7, and drives the locking cylinder to be separated from the locking groove through the pulling wire7. When the locking cylinder is driven to be separated from the locking groove by the pulling wire 7, the rotation angle of the handle 1 may not be limited. For example, in one embodiment, when the pulling wire 7 drives the locking cylinder to be separated from the locking groove, the rotation angle of the handle 1 may be at least 25 degrees.
Wherein, the first driving component 6 and the second driving component 8 may also be set as an integral structure, so as to improve a utilization rate of a space of the inner handle for automobile. For example, in one embodiment, a driving component is connected with the handle 1. The driving component is provided with the protrusion 601 and the notch 602, and the pulling wire 7 is also connected with the driving component. Therefore, when the door body is not opened, the contacting point 5 of the micro switch is located in the notch 602. When the handle 1 is opened at a certain angle, for example, when the angle is from 10 degrees to 20 degrees, the protrusion 601 triggers the contacting point 5 of the micro switch. The contacting point 5 of the micro switch is triggered by the protrusion 601 to turn on the motor and unlock the locking structure 10. Further, when the handle 1 is continuously opened at a certain angle, for example, when the angle is greater than 25 degrees, the second driving component 8 pulls the pulling wire 7 and drives the locking cylinder to be separated from the locking groove through the pulling wire 7. The pulling wire 7 is pulled by the driving component 8 to realize an unlocking of the locking structure 10.
In summary, the disclosure provides the inner handle for automobile, which is provided with the micro switch of the electric door on the handle. In an opening process of the handle of the inner handle, first the micro switch is touched to realize an opening of the electric door. Then the handle continues to be pulled after touching the micro switch, in order to reach an unlocking state to achieve a mechanical unlocking. Therefore, by arranging an electric switch of a vehicle door in the inner handle, an additional electric switch is avoided, and the actual use effect of the inner handle is improved.
The above-mentioned embodiments merely illustrate the principles and effects of the disclosure, but are not intended to limit the disclosure. Anyone skilled in the art may modify or change the above embodiments without departing from the range of the disclosure. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the range and technique disclosed in the disclosure should still be covered by the claims of the disclosure.
