Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an inner door handle structure, a door and a vehicle. Background Art

[0002] At present, the opening limit structure of the gooseneck inner handle of the car door on the market is designed on the door handle base. The limit structure is arranged on the door handle base to limit the inner handle during the opening process of the inner handle.

[0003] During the opening process of the gooseneck inner handle, there are two main ways for the limiting structure to limit the inner handle. The first way is to limit the inner handle along the Y direction of the vehicle, that is, the limiting structure is designed at the gooseneck position of the inner handle. When the inner handle is opened to the maximum angle, the gooseneck position of the inner handle and the limiting structure (for example, the limiting surface) on the door handle base are offset in the Y direction for limiting. In this limiting method, in order to smoothly assemble the inner handle to the door handle base, it is necessary to open a larger through hole on the door handle base so that the gooseneck of the inner handle and its rear structure can pass through the through hole and be assembled to the door handle base. In this case, when the inner handle is opened to the maximum angle, the gap between the through hole opened on the door handle base and the gooseneck of the inner handle is large, resulting in poor appearance. The second way is to limit the inner handle along the X direction of the vehicle, that is, the limiting structure is designed at the rear of the gooseneck of the inner handle. When the inner handle is opened to the maximum angle, the limiting structure and the limiting structure (for example, the limiting surface) on the door handle base are offset and limited in the X direction. In this limiting method, the inner structure of the door handle base is disconnected at the gooseneck position to facilitate the assembly of the inner handle to the door handle base. However, at the same time, the door panel needs to have a larger size in the Y direction of the vehicle, and the door needs to be thicker so that there is enough space to accommodate the limiting structure. In addition, this limiting method cannot crimp the edge of the soft covering on the inner surface of the door at the gooseneck position of the inner handle. Therefore, it cannot be directly matched with the soft covering, affecting the appearance quality of the inner surface of the door. Utility Model Content

[0004] The utility model aims to solve the above technical problem, that is, to solve the problem that the existing inner door handle is inconvenient to install the handle on the base.

[0008] Furthermore, the limiting portion includes a first limiting surface opposite to the limiting block; the limiting block includes a second limiting surface opposite to the limiting portion; when the handle rotates around the rotating shaft, the handle is limited by the abutment between the first limiting surface and the second limiting surface.

[0009] Furthermore, the radius from the contour line of the arc portion to the rotation axis is the same.

[0010] Furthermore, a counterweight block is arranged on the limiting portion.

[0011] Furthermore, a soft covering piece is arranged on the surface of the base; and a protrusion is arranged on the surface of the limiting block which is opposite to the limiting portion, so as to press the edge of the soft covering piece.

[0012] Furthermore, a concave portion adjacent to the protruding portion is provided on a surface of the limiting block opposite to the limiting portion, and the concave portion and the protruding portion form a space for accommodating wrinkles at the edge of the soft covering component.

[0035] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0036] First, it should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "longitudinal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0037] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0038] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a door inner handle structure, comprising: a base 1, a handle 2 and a stopper 3. The base 1 is fixed to the inner side of the door; the handle 2 is rotatably arranged on the base 1 around a rotation axis 4; the stopper 3 is detachably arranged on the base, and limits the handle 2 when the handle 2 rotates around the rotation axis 4.

[0039] like Figure 3 and Figure 7 As shown, the base 1 comprises: a receiving portion 11 and an opening 12 , and the receiving portion 11 forms a receiving area 13 .

[0040] like Figure 1 , Figure 3 , Figure 4 and Figure 7As shown, the handle 2 includes a handle portion 21, an arc portion 22, a limit portion 23 and a hand-grip hole 25 which are connected in sequence. The handle 2 is connected to the base 1 via the rotation shaft 4 through the limit portion 23; the handle portion 21 can be accommodated in the accommodation area 13 of the base 1; the arc portion 22 passes through the opening 12 on the base 1 to connect the handle portion 21 with the limit portion 23. A reset spring 6 is also provided on the rotation shaft 4, so that the handle portion 21 of the handle 2 is accommodated in the accommodation area 13 of the base 1 under the action of the restoring force of the reset spring 6. A sleeve can also be provided outside the rotation shaft 4.

[0041] When the user pulls the handle portion 21 of the handle 2 outward through the hand hole 25 of the handle 2, the handle 2 is driven to rotate around the rotation axis 4. During the rotation process, the handle 2 pulls the door lock cable of the vehicle door to perform the unlocking operation, so that the handle 2 unlocks the vehicle door. During this process, the return spring 6 is compressed. When the user releases the handle portion 21, the handle 2 will rotate around the rotation axis 4 under the action of the restoring force of the return spring 6, so that the handle portion 21 returns to the accommodating area 13 and completes the reset. Figure 4 and Figure 7 As shown, a counterweight 5 may also be provided at the limiting portion 23 of the handle 2, which can improve the inertia resistance of the handle 2, so that when the vehicle collides from the side, the door is impacted by a huge force, and the handle 2, under the action of the counterweight 5, keeps the door closed and does not open.

[0042] like Figure 2 and Figures 5 to 8 As shown, the limiting portion 23 includes a first limiting surface 24 opposite to the limiting block 3; the limiting block 3 includes a second limiting surface 31 opposite to the limiting portion 23. When the user pulls the handle portion 21 of the handle 2 outwards to rotate the handle 2 around the rotation axis 4 to unlock the door, the first limiting surface 24 of the limiting portion 23 abuts against the second limiting surface 31 of the limiting block 3, so that after the door is unlocked, the rotation stroke of the handle portion 21 of the handle 2 can be limited.

[0043] The limit block 3 can be detachably fixed to the base 1 by fasteners. For example, the limit block 3 and the base 1 can be detachably fastened by screws. Alternatively, an insert nut can be designed on the limit block 3, and the limit block 3 and the base 1 can be detachably fastened by bolts. This solution of detachably connecting the limit block 3 to the base 1 allows the handle 2 to be assembled to the base 1 first, and then the limit block 3 to be assembled to the base 1, when assembling the inner door handle, which greatly improves the assembly convenience and efficiency of the handle 2.

[0044] Furthermore, if Figure 3 and Figure 4 as well as Figure 7 and Figure 8As shown, the radius of the contour line of the arc portion 22 of the handle 2 to the rotating shaft 4 is the same, so that the arc portion 22 of the handle 2 is an arc segment with the axis of the rotating shaft 4 as the center axis. When the user pulls the handle portion 21 of the handle 2 outward from the accommodating area 13, the arc portion 22 of the handle 2 will rotate around the axis of the rotating shaft 4 in the opening 12 of the base 1. Since the distance from the contour line of the entire arc portion 22 to the axis of the rotating shaft 4 is the same, the motion trajectory of the contour line of the entire arc portion 22 is an arc with a fixed radius, and the motion trajectory will not change in the radial direction, so that the gap between the opening 12 and the matching wall 121 opposite to the arc portion 22 can be maintained at a fixed value that is as small as possible. In addition, as Figure 3 and Figure 4 As shown, the shape of the matching wall 121 of the opening 12 can also be set to be the same as the shape of the contour line of the cross section of the arc portion 22 of the handle 2, so as to minimize the gap value between the arc portion 22 of the handle 2 and the matching wall 121 of the opening 12. In this way, the size of the opening can be made as small as possible. In a specific embodiment, the gap between the arc portion 22 of the handle 2 and the matching wall 121 of the opening 12 can be controlled to be 1.5 mm.

[0045] Because the gap between the arc portion 22 of the handle 2 and the matching wall 121 of the opening 12 can be controlled to a very small value, and whether the arc portion 22 of the handle 2 and the opening 12 are relatively stationary or the arc portion 22 of the handle 2 rotates in the opening 12, the gap between the arc portion 22 of the handle 2 and the opening 12 remains unchanged. This allows the internal structure of the door to be well shielded, and when the user pulls the handle 2 to unlock the door, the internal components of the door will not be seen through the gap between the arc portion 22 of the handle 2 and the matching wall 121 of the opening 12. This not only makes the door have a good appearance, but also allows users to have a good use experience.

[0046] like Figures 9 to 12 As shown, a soft covering member 7 is provided on the surface of the base 1. The soft covering member 7 includes a soft covering frame 72 and a soft covering layer 71 wrapped around the soft covering frame 72. The soft covering frame 72 is connected to the base 1 so that the soft covering layer 71 covers the surface of the base 1 except the receiving area 13. Fig.11 and Fig.12As shown, a protrusion 32 is provided on the surface of the stop block 3 that is away from the stop portion 23 of the handle 2. When the soft covering member 7 covers the stop block 3, the soft covering layer 71 will be turned over at the end of the soft covering skeleton 72 to between the soft covering skeleton 72 and the stop block 3. By providing the protrusion 32 on the surface of the stop block 3 that is away from the stop portion 23 of the handle 2, that is, on the surface opposite to the stop block 3 and the soft covering member 7, the soft covering layer 71 turned over to between the soft covering skeleton 72 and the stop block 3 can be pressed against the soft covering skeleton 72 near the end of the soft covering skeleton 72. At the same time, a recess 33 adjacent to the protrusion 32 is provided on the surface of the stop block 3 that is away from the stop portion 23. A space is formed between the recess 33 and the protrusion 32 to accommodate the wrinkles at the end of the soft covering layer 71 turned over to between the soft covering skeleton 72 and the stop block 3.

[0047] The protrusion 32 of the limit block 3 uniformly presses the soft covering layer 71 along the Y-axis direction of the vehicle coordinate system, and the recess 33 and the protrusion 32 form a space to accommodate possible wrinkles or waves of the soft covering layer 71 after it is flipped over to between the soft covering skeleton 72 and the limit block 3, thereby ensuring the consistency and stability of the crimping of the soft covering layer 71 of the soft covering part 7 by the limit block 3, so that the inner door handle has a good appearance.

[0048] An embodiment of the present application also provides a vehicle door, which includes the inner door handle structure as described above.

[0049] An embodiment of the present application also provides a vehicle, which includes the vehicle door as described above.

[0050] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
