[0045] Figure 1 1 is a schematic structural diagram of an inner handle assembly according to one embodiment of the present disclosure. Figure 2 2 is a schematic structural diagram of an inner handle assembly according to an embodiment of the present disclosure from another angle.
[0046] like Figure 1 and Figure 2 As shown, the interior handle assembly of the present disclosure can be installed on a vehicle door or a vehicle body, for example, installed on a side door of the vehicle, and can be used to unlock a side door lock installed on the vehicle door.
[0047] That is, at this time, the side door of the vehicle is provided with a side door lock, which is an electric side door lock having an electric unlocking function and a mechanical unlocking function. Accordingly, when the inside handle assembly of the present disclosure is operated, the side door lock can be electrically unlocked and / or mechanically unlocked.
[0048] In the present disclosure, the inner handle assembly includes a fixing portion 110 , an operating portion 120 and a trigger switch 130 .
[0049] The fixing portion 110 forms the housing of the interior handle assembly of the present disclosure. In one embodiment, it can be formed as a separate component and can be fixed to the vehicle door during use. In another embodiment, the fixing portion 110 can also be formed as part of the vehicle door, which is not limited by the present disclosure.
[0050] The fixing portion 110 is formed with an internal space. Accordingly, components such as the operating portion 120 and the trigger switch 130 can be at least partially disposed in the internal space of the fixing portion 110 .
[0051] Accordingly, the fixing portion 110 includes two opposing side walls that at least partially define the interior space. Furthermore, the fixing portion 110 includes a bottom wall having an opening formed therein, thereby enabling at least a portion of the operating portion 120 of the present disclosure to be located outside the fixing portion 110 under certain conditions. Furthermore, components such as a pull wire or connecting rod connected to the operating portion 120 also pass through the opening and exit to the exterior of the fixing portion 110.
[0052] In a preferred embodiment, a buffer device may be provided inside the fixing portion 110 to reduce noise when the operating portion 120 contacts the fixing portion 110. More preferably, the buffer device may be a pad made of elastic material such as a rubber pad or a silicone pad.
[0053] The operating portion 120 is disposed on the fixed portion 110 and is configured to be movable relative to the fixed portion 110. In other words, the operating portion 120 is not fixed to the fixed portion 110, but is configured to be movable relative to the fixed portion 110. The movement of the operating portion 120 relative to the fixed portion 110 may include translation and / or rotation, etc. This disclosure is not limited to this.
[0054] In the structures shown in the various drawings of the present disclosure, the operating portion 120 is capable of rotating relative to the fixing portion 110 . The structure of the inner handle assembly of the present disclosure will be described in detail below in conjunction with the rotation of the operating portion 120 .
[0055] Figure 3 2 is a schematic structural diagram of an operating portion of an inner handle assembly according to one embodiment of the present disclosure.
[0056] like Figures 1 to 3 As shown, in the present disclosure, an axis component 140 is disposed between the two side walls of the fixed portion 110. For example, both side walls of the fixed portion 110 have through-holes, and the ends of the axis component 140 are respectively disposed within the through-holes of the two side walls. Furthermore, the axis component 140 passes through the operating portion 120, allowing the operating portion 120 to rotate about the axis component 140, thereby enabling the operating portion 120 to rotate relative to the fixed portion 110.
[0057] In the present disclosure, both ends of the shaft member 140 are rotatable relative to the side wall. In this case, the shaft member 140 can be fixed to the operating portion 120, or the shaft member 140 can be rotatably disposed in the through hole formed in the operating portion 120. In another case, both ends of the shaft member 140 are fixed relative to the side wall. In this case, the shaft member needs to be rotatably disposed in the through hole formed in the operating portion 120.
[0058] In the present disclosure, the operating portion 120 includes an initial position, a first trigger position, and a second trigger position. When the operating portion 120 is not operated, it can be maintained in the initial position. Specifically, a limiting structure 160 can be provided on the side wall of the fixing portion 110, and the limiting structure 160 can be used to limit the operating portion 120 to the initial position.
[0059] When the operating portion 120 is operated, that is, when an external force is applied to the operating portion 120 , the operating portion 120 will rotate and leave the initial position and move toward the first trigger position and the second trigger position.
[0060] Figure 4 3 is a structural diagram of an operating portion located at a first triggering position according to an embodiment of the present disclosure. Figure 5 3 is a structural diagram of an operating portion located at a second triggering position according to an embodiment of the present disclosure.
[0061] like Figure 1 、 Figure 4 and Figure 5 As shown, Figure 1 The operating part 120 is located at the initial position. Figure 1 When the operating part 120 in the middle of the operation part 120 leaves the initial position and reaches the Figure 4 When the operating portion 120 is pressed further, the operating portion 120 will continue to move and reach the first trigger position. Figure 5 The second trigger position.
[0062] In other words, the interior handle assembly of the present disclosure seamlessly combines electric and mechanical unlocking with a simple push. During normal use and in emergency situations, the door can be unlocked simply by pressing the operating portion 120 (or the handle). Unlike conventional handles, which require a complicated operation of pressing the handle for electric unlocking and pulling the handle for mechanical unlocking, the interior handle assembly can be unlocked in the same direction as the door opening. This facilitates escape for those inside.
[0063] Accordingly, in the initial position, the side door lock may be in a locked state; in the first trigger position, the trigger switch 130 is triggered; and in the second trigger position, the side door lock is mechanically unlocked.
[0064] In the present disclosure, the trigger switch 130 is provided on the fixing portion 110 , and when the operating portion 120 moves relative to the fixing portion 110 , the trigger switch 130 is triggered, and the side door lock is electrically unlocked.
[0065] Specifically, the trigger switch 130 may be a micro switch or a Hall switch. When the trigger switch 130 is a micro switch and the operating portion 120 is in the initial position, the micro switch may be in a closed state. Accordingly, when the operating portion 120 reaches the first trigger position, the micro switch is in an open state, generating a trigger signal. On the other hand, when the operating portion 120 is in the initial position, the micro switch may be in an open state. Accordingly, when the operating portion 120 reaches the first trigger position, the micro switch is in a closed state, and a trigger signal can also be generated.
[0066] Since the working principle of the trigger switch 130 may be similar to that of the micro switch, it will not be described in detail in this disclosure.
[0067] Then, when the operating portion 120 is operated and continues to move, the operating portion 120 is used to mechanically unlock the side door lock. At this time, the operating portion 120 is connected to the side door lock via a pull wire or a connecting rod. When the operating portion 120 continues to rotate to the second trigger position, the pull wire or connecting rod is pulled, which can activate the mechanical unlocking device of the side door lock and realize mechanical unlocking of the side door lock.
[0068] In the present disclosure, the inner handle assembly further includes: a first return spring 170. When the operating portion 120 moves from the initial position to the first trigger position, only the first return spring 170 is further twisted, and its elastic potential energy increases.
[0069] Specifically, the first return spring 170 can be wound around the shaft member 140, with one end of the first return spring 170 hooked to the fixing portion 110 and the other end hooked to the operating portion 120. Thus, when the operating portion 120 is pressed, the first return spring 170 can always be in a state of gradually increasing elastic potential energy. Conversely, when the pressing force applied to the first return spring 170 disappears, the operating portion 120 can be restored to its initial position due to the elastic potential energy of the first return spring 170.
[0070] In addition, the inner handle assembly further includes a second return spring 180 . When the operating portion 120 moves from the first trigger position to the second trigger position, the elastic potential energy of the first return spring 170 and the second return spring 180 both increase.
[0071] More specifically, a support shaft 150 is disposed between the two sidewalls of the fixed portion 110. A second return spring 180 is wound around the support shaft 150, with one end connected to (hook onto) the fixed portion 110 and the other end suspended in the air. Furthermore, during the movement of the operating portion 120 from its initial position to the first trigger position, the operating portion 120 and the second return spring 180 do not contact each other, thereby enabling the side door lock to be electrically unlocked with minimal force. Furthermore, during the movement of the operating portion 120 from the first trigger position to the second trigger position, the operating portion 120 can contact the other end of the second return spring 180, compressing it and increasing its elastic potential energy.
[0072] In the present disclosure, the elastic coefficient of the second return spring 180 is greater than the elastic coefficient of the first return spring 170. Therefore, in the initial stage, only the small elastic spring is active, making it easier for people to trigger the trigger switch. Adding a large spring during the mechanical unlocking stage can provide a fixed small pressing stroke during electric unlocking without activating the mechanical stroke, improving the customer experience.
[0073] In a preferred embodiment, the operating portion 120 can be made of different colors and / or different materials to achieve aesthetic and practical effects.
[0074] When the side door lock of the present invention is in use, the locking rod can prevent the side door lock from being opened, that is, the side door lock can have functions such as child protection. Regarding the structure of the side door lock, the solution in the prior art can be adopted, and the present invention will not elaborate on it one by one.
[0075] In the description of this specification, the description with reference to the terms "one embodiment / method", "some embodiments / methods", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment / method or example are included in at least one embodiment / method or example of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment / method or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments / methods or examples. In addition, those skilled in the art may combine and combine different embodiments / methods or examples described in this specification and the features of different embodiments / methods or examples, unless they are contradictory.
[0076] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.
[0077] Those skilled in the art will appreciate that the above embodiments are merely intended to clearly illustrate the present disclosure and are not intended to limit the scope of the present disclosure. Other changes or modifications may be made based on the above disclosure, and such changes or modifications are still within the scope of the present disclosure.
