Description

Technical Field

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

[0002] The door opening handle is a functional component commonly used by drivers and passengers. It mainly consists of a handle and a base, and the specific structure of the handle has a direct impact on the opening performance of the handle. When the handle is opened to the limit position, there will be a corresponding structure on the base to prevent the handle from opening further. This is the limit structure between the handle and the base.

[0003] At present, the inner opening handle usually adopts a limit structure set on one side of the handle to perform unilateral limit. However, since the handle is restricted by the unilateral limit, it is easy to generate a torsional moment perpendicular to the pin when opening, causing the handle structure to be biased to one side as a whole, affecting the opening performance. Moreover, the limit structure is usually set in the rear half of the handle. In order to ensure the strength performance of the handle, it is usually necessary to increase the thickness of the rear half of the handle to improve the strength, resulting in a bulky handle structure as a whole and high production cost.

[0032] It should be noted that the terms "first", "second", etc. in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein.

[0033] Combination Figures 1 to 3As shown, an embodiment of the utility model provides an inner door opening handle structure, including a handle 1 and a base 2, the handle 1 includes a connecting portion 11 and a gripping portion 12, the gripping portion 12 is connected to the side of the connecting portion 11 facing the interior of the vehicle, the connecting portion 11 is rotatably connected to the base 2, a first limiting structure 3 is provided between the connecting portion 11 and the base 2, a second limiting structure 4 is provided between the gripping portion 12 and the base 2, and the first limiting structure 3 and the second limiting structure 4 are respectively located on both sides of the connecting portion 11 along the vertical direction, and are used to limit the rotation angle of the handle 1 relative to the base 2 when the handle 1 is opened.

[0034] It should be noted that the interior door opening handle structure is usually installed on the inner side of the left door and the right door, that is, the side of the left door and the right door facing the interior space of the vehicle, wherein the interior door opening handle structure installed on the left door is referred to as the left interior door opening handle, and the interior door opening handle structure installed on the right door is referred to as the right interior door opening handle, and the left interior door opening handle and the right interior door opening handle are usually symmetrically arranged. When in use, the door is unlocked in the vehicle by pulling the handle 1 of the interior door opening handle structure (i.e., opening handle 1). When handle 1 is pulled, handle 1 is in the open state. At this time, the door is unlocked. After handle 1 is released, handle 1 automatically resets to the closed state. For the convenience of description, here and in the following text, "interior door opening handle" is used as the opening handle. Figures 1 to 9 The left door inner opening handle shown in the figure is taken as an example for detailed description.

[0035] Specifically, for the left door inner opening handle, the right side of the connecting portion 11 of the handle 1 faces the interior space of the vehicle, so the side of the connecting portion 11 facing the interior of the vehicle refers to the right side of the connecting portion 11 (that is, the connecting portion 11 is located at Figure 1 The handle 1 is connected to the right side of the connecting portion 11, and the handle 12 is connected to the right side of the connecting portion 11, and the handle 12 is usually used for the driver to hold it, so that the driver can unlock the door from inside the car by pulling the handle 1. In addition, the connecting portion 11 is used to rotate relative to the base 2 around an axis parallel to the vertical direction, that is, the connecting portion 11 of the handle 1 is also rotatably connected to the base 2, and the rotation axis is parallel to the vertical direction, that is, Figure 1In the middle Z-axis direction; the connection part 11 and the base 2 can be connected in rotation by using the pin shaft 5 described later, or by setting a rotating shaft in one of the connection part 11 and the base 2 and setting an axial hole in the other, and realizing the rotation connection by matching the rotating shaft and the axial hole, which is not specifically limited here. A first limiting structure 3 is provided between the lower end of the outer side of the connection part 11 (i.e., the lower end of the side of the connection part 11 facing the outside of the vehicle) and the base 2, that is, the first limiting structure 3 is roughly located at the lower side of the connection part 11 (i.e., the connection part 11 is located on the side opposite to the Z-axis), and at the same time, a second limiting structure 4 is provided between the upper end of the outer side of the gripping part 12 (i.e., the lower end of the side of the gripping part 12 facing the outside of the vehicle) and the base 2, and the gripping part 12 is usually connected to the upper end of the outer side of the connection part 11, so the second limiting structure 4 is roughly located at the upper side of the connection part 11 (i.e., the connection part 11 is located on the side of the positive direction of the Z-axis), that is, the first limiting structure 3 and the second limiting structure 4 are respectively located at the upper and lower sides of the connection part 11. During the process of pulling the handle, that is, during the process of opening the handle, the handle 1 rotates toward the inside of the vehicle relative to the base 2 around the vertical axis, that is, rotates along the opening direction. When the handle 1 abuts the base 2 at the first limiting structure 3 and the second limiting structure 4, the handle 1 stops rotating. At this time, the rotation angle of the handle 1 reaches the maximum. When the handle is released, that is, when the handle is closed, the handle 1 rotates in the opposite direction to the initial closed state.

[0036] In this embodiment, the first limiting structure 3 can be provided between the connection part 11 of the handle 1 and the base 2, and the second limiting structure 4 can be provided between the gripping part 12 of the handle 1 and the base 2, so as to limit the opening of the handle 1 by using the double limiting structure. Moreover, when the handle 1 and the base 2 are in contact at the first limiting structure 3 and the second limiting structure 4, the force applied to the handle 1 can be transmitted to the base 2 via the connection part 11 and the gripping part 12, respectively, so that the force transmission of the handle structure in the door is uniform. At the same time, by providing the first limiting structure 3 and the second limiting structure 4 on both sides of the connection part 11 in the vertical direction, the two limiting structures are distributed on the upper and lower sides of the connection part 11, so as to ensure that the handle 1 is uniformly stressed when it is opened, prevent the handle 1 from forming a torsional moment perpendicular to the rotation axis of the handle 1 when it is opened, and thus avoid the handle 1 from tilting due to the torsional moment (i.e., the handle 1 flips and deforms), thereby ensuring the stability of the handle 1 when it is opened. In addition, the provision of the first limiting structure 3 and the second limiting structure 4 enables the handle 1 to have higher strength and stability when opened. Thus, there is no need to increase the thickness of the handle 1, for example, the rear half, to enhance its strength, thereby reducing the overall weight of the opening handle structure in the vehicle door to a certain extent.

[0037] Optionally, combined Figures 3 to 5As shown, the first limiting structure 3 includes a first limiting surface 31 and a second limiting surface 32. The base 2 is provided with a first abutting portion 21. The first limiting surface 31 and the second limiting surface 32 are respectively provided on the connecting portion 11 and the first abutting portion 21, and are used to fit together when the handle 1 rotates a first preset angle.

[0038] And / or, the second limiting structure 4 includes a third limiting surface 41 and a fourth limiting surface 42, the base 2 is provided with a second abutting portion 22, the third limiting surface 41 and the fourth limiting surface 42 are respectively provided on the gripping portion 12 and the second abutting portion 22, and are used to fit together when the handle 1 rotates at a second preset angle;

[0039] When the first limiting structure 3 includes the first limiting surface 31 and the second limiting surface 32 , and the second limiting structure 4 includes the third limiting surface 41 and the fourth limiting surface 42 , the first preset angle is less than or equal to the second preset angle.

[0040] Specifically, the first limiting surface 31 is usually arranged at the lower end of the outer side of the connecting portion 11, the first abutting portion 21 is usually arranged between the first ear plate 23 (described later) and the second ear plate 24 (described later) of the base 2, and the second limiting surface 32 is usually arranged at one end of the first abutting portion 21 close to the first ear plate 23; the third limiting surface 41 is arranged on the side of the gripping portion 12 facing the base 2, the fourth limiting surface 42 is usually an inclined structure, and is arranged on the second abutting portion 22, and the second abutting portion 22 is usually arranged on the second ear plate 24 of the base 2. The first preset angle and the second preset angle are usually angle values ​​preset by the designer according to experiments or experience, and when the first limiting surface 31 and the second limiting surface 32 are used to fit together when the handle 1 rotates the first preset angle, and the third limiting surface 41 and the fourth limiting surface 42 are used to fit together when the handle 1 rotates the second preset angle, the second preset angle is usually equal to or slightly greater than the first preset angle. For example, in one example, the first preset angle can be set to 40°, and the second preset angle can be set to slightly greater than 40°. When the pull handle 1 is rotated by the first preset angle, the first limiting surface 31 and the second limiting surface 32 are fitted together, that is, the handle 1 and the base 2 are in surface-to-surface contact through the first limiting structure 3. At this time, a small gap is formed between the handle 1 and the base 2 at the second limiting structure 4, or only a contact without an extrusion force is formed, and the first limiting structure 3 is used as a primary contact structure to first play a limiting role, preventing the handle 1 from continuing to rotate in the opening direction; when the handle 1 is deformed due to the continued opening force, that is, when the handle 1 is rotated by the second preset angle, the handle 1 and the base 2 form an extrusion relationship at the second limiting structure 4, that is, the second limiting structure 4 starts to play a limiting role as a secondary contact structure. At this time, the second limiting structure 4 and the first limiting structure 3 together resist the opening force of the handle 1.

[0041] In this embodiment, by setting the first limiting structure 3 and / or the second limiting structure 4 as limiting surfaces, the handle 1 and the base 2 are in surface contact when the handle 1 is opened, thereby increasing the contact area between the handle 1 and the base 2 when they are in contact, reducing the pressure at the contacting portion, and further reducing the risk of deformation of the handle 1 and the base 2 at the contacting portion. In addition, by setting the first preset angle to be equal to or slightly smaller than the second preset angle, the double limiting structures are used to perform limiting functions in sequence, thereby preventing the handle 1 from being greatly deformed due to excessive opening force.

[0042] Optionally, combined Figure 4 , Figure 6 and Figure 8 As shown, the door opening handle structure also includes a pin shaft 5, a first connecting hole 112 is provided on the connecting part 11, and a second connecting hole 25 is provided on the base 2, the axes of the first connecting hole 112 and the second connecting hole 25 are parallel to the vertical direction, and the connecting part 11 and the base 2 are rotatably connected at the first connecting hole 112 and the second connecting hole 25 through the pin shaft 5.

[0043] In this embodiment, a first connecting hole 112 and a second connecting hole 25 are respectively provided on the connecting portion 11 and the base 2, so that the rotational connection between the handle 1 and the base 2 can be realized by passing the pin 5 through the first connecting hole 112 and the second connecting hole 25. The structure is simple and the disassembly and assembly are convenient.

[0044] Optionally, combined Figure 4 and Figure 6 As shown, a first ear plate 23 and a second ear plate 24 are spaced apart on the base 2 . The first ear plate 23 and the second ear plate 24 are respectively provided with a second connecting hole 25 , and the connecting portion 11 is located between the first ear plate 23 and the second ear plate 24 .

[0045] In this embodiment, two ear plate structures, namely a first ear plate 23 and a second ear plate 24, are provided on the base 2, and a second connecting hole 25 is provided on the ear plate structure to provide an installation position for the pin 5, thereby facilitating the installation of the pin 5. At the same time, the connecting portion 11 is provided between the two ear plate structures to reduce the overall size of the opening handle structure inside the door in the vertical direction, thereby reducing the space occupied by the opening handle structure inside the door and facilitating the layout.

[0046] Optionally, in combination with FIG. Figure 6 and Figure 7 As shown, the first abutment portion 21 is located between the first ear plate 23 and the second ear plate 24, and is respectively connected to the first ear plate 23 and the second ear plate 24, the second limiting surface 32 is provided at one end of the first abutment portion 21 connected to the first ear plate 23, and the second abutment portion 22 is connected to the side of the second ear plate 24 facing the gripping portion 12.

[0047] In this embodiment, the second ear plate 24 is usually located above the first ear plate 23, and the upper end of the pin 5 is penetrated on the second ear plate 24, and the lower end is penetrated on the first ear plate 23. Since the fourth limiting surface 42 of the second limiting structure 4 is arranged on the second abutting portion 22, and the second abutting portion 22 is connected to the second ear plate 24 and located on the inner side of the second ear plate 24, the fourth limiting surface 42 of the second limiting structure 4 is approximately located at the upper end of the pin 5. The upper and lower ends of the first abutting portion 21 are usually connected to the front end of the second ear plate 24 and the front end of the first ear plate 23, respectively, and the second limiting surface 32 is arranged at one end of the first abutting portion 21 close to the first ear plate 23, so the second limiting surface 32 of the first limiting structure 3 is approximately located at the lower end of the pin 5. In this way, by arranging the second limiting surface 32 at one end of the first abutting portion 21 connected to the first ear plate 23, and connecting the second abutting portion 22 to the side of the second ear plate 24 facing the holding portion 12, the second limiting surface 32 of the first limiting structure 3 is roughly located at the lower end of the pin 5, and the fourth limiting surface 42 of the second limiting structure 4 is roughly located at the upper end of the pin 5, thereby ensuring that the two limiting structures are distributed at both ends of the pin 5, and further ensuring that the handle 1 is subjected to uniform force when it is opened.

[0048] Optionally, combined Figure 1 , Figure 2 and Figure 7 As shown, a fifth limiting surface 26 is further provided on the second abutting portion 22 . The fifth limiting surface 26 is arranged at an obtuse angle with the fourth limiting surface 42 and is used to fit with the fourth limiting surface 42 when the handle 1 is closed.

[0049] In this embodiment, the fifth limiting surface 26 is usually connected to the front end of the fourth limiting surface 42 and is set at an obtuse angle with the fourth limiting surface 42. When the handle 1 is closed, the handle 1 rotates around the vertical axis toward the outside of the vehicle, that is, rotates in the closing direction. When the fourth limiting surface 42 on the gripping portion 12 is in contact with the fifth limiting surface 26 on the second abutting portion 22, the fifth limiting surface 26 prevents the handle 1 from continuing to rotate in the closing direction and limits the handle 1 to the initial position, that is, the position where the handle 1 is in the closed state, which is also the position where the handle 1 is in the closed state. Figure 1 The position of the middle handle 1 relative to the base 2. In this way, the fifth limiting surface 26 is provided to limit the closing of the handle 1, so that the handle 1 can be kept in the initial position that is easy to pull after closing, thereby facilitating the driver and passenger to use the handle 1 to open the door in the car.

[0050] Optionally, combined Figure 8 and Fig. 9 As shown, a boss structure 113 is protruded from one or both ends of the connecting portion 11 along the vertical direction, and the first connecting hole 112 passes through the boss structure 113 .

[0051] In this embodiment, the boss structure 113 is arranged at the upper end and / or lower end of the connecting part 11 and is located at the first connecting hole 112. In this way, the boss structure 113 can be used to improve the rigidity and strength of the installation position of the pin shaft 5 to ensure the stability of the rotational connection between the handle 1 and the base 2.

[0052] Optionally, combined Figure 8 and Fig. 9 As shown, a transition fillet 13 is provided at the connection between the connection portion 11 and the grip portion 12. Thus, by performing a chamfering process, for example, at the connection between the connection portion 11 and the grip portion 12 to form the transition fillet 13, on the one hand, the concentrated stress at the connection between the connection portion 11 and the grip portion 12 can be reduced to improve the strength of the handle 1, and on the other hand, interference between the handle 1 and the base 2 at the connection can be avoided.

[0053] Optionally, combined Figure 8 As shown, a first weight-reducing hole 121 is provided on the side of the grip 12 facing the base 2, and / or a second weight-reducing hole 122 is provided at the end of the grip 12 in the vertical direction. In this way, the first weight-reducing hole 121 and / or the second weight-reducing hole 122 can be used to realize a lightweight design of the rear half structure of the handle 1, which is convenient for processing; moreover, the first weight-reducing hole 121, which is the main weight-reducing structure, is provided on the side of the grip 12 facing the base 2, that is, provided on the outside of the grip 12, so as to hide the first weight-reducing hole 121, thereby improving the aesthetics.

[0054] Furthermore, combined with Figure 8 As shown, a reinforcing rib 123 is provided in the first lightening hole 121. In this way, the reinforcing rib 123 can be used to increase the local structural strength of the handle 1 at the first lightening hole 121 to prevent the handle 1 from deforming when subjected to an opening force.
