[0002] Currently, the door lock opening mechanism in automobiles mainly involves a rotatable strip handle that directly moves the door lock cable to open the door. However, the current door lock opening mechanism is not very smooth and requires considerable effort to open. Utility Model Content

[0003] In view of the above, it is necessary to propose a door handle structure, door assembly and vehicle to improve the smoothness of opening the door lock and make it more effortless.

[0004] In a first aspect, embodiments of this application provide a door handle structure, comprising: a support assembly; a swing arm rotatably disposed on the support assembly, the swing arm having a first end and a second end disposed opposite to each other, the rotation axis of the swing arm being located between the first end and the second end, the distance between the first end and the rotation axis of the swing arm being less than the distance between the second end and the rotation axis of the swing arm, the first end being configured to be connected to a door lock cable; a moving assembly slidably disposed on the support assembly and movably connected to the second end, the moving assembly having a rack portion, the extending direction of the rack portion being the same as the sliding direction of the moving assembly; and a handle rotatably disposed on the support assembly, the handle having a gear portion, the gear portion meshing with the rack portion.

[0005] In some embodiments, the support assembly includes an assembly, a support member, and a rotating shaft. The adjacent side walls of the assembly are respectively provided with an assembly groove and a clearance opening. The clearance opening communicates with the assembly groove. The support member is disposed in the assembly groove and protrudes from the assembly groove. The moving assembly is slidably disposed on the portion of the support member protruding from the assembly groove. The handle is rotatably disposed on the portion of the support member protruding from the assembly groove and located on the side of the moving assembly away from the assembly groove. The rotating shaft passes through the swing arm and is located at the clearance opening. The two ends of the rotating shaft are respectively connected to the two side walls of the assembly groove.

[0006] In some embodiments, the first end has a slot configured to connect to the pull wire.

[0007] In some embodiments, the second end is provided with a movable elongated hole, the extension direction of which is perpendicular to the extension direction of the rotation axis of the swing arm; the door handle structure further includes a movable shaft, the extension direction of which is parallel to the extension direction of the rotation axis of the swing arm, the movable shaft is inserted into the movable elongated hole and connected to the moving component.

[0008] In some embodiments, the first end has two limiting plates, which are spaced apart along the extension direction of the movable shaft. There are two movable elongated holes, which are respectively opened in the two limiting plates and are arranged opposite to each other. The moving component extends between the two limiting plates, and the movable shaft passes through the portion of the moving component that extends between the two limiting plates. Both ends of the movable shaft are respectively inserted into the two movable elongated holes.

[0009] In some embodiments, the moving component includes a slider and a transmission component, the slider being slidably disposed on the support component, the transmission component being connected to the slider, and the rack portion being disposed on the transmission component.

[0010] In some embodiments, there are two transmission members, two racks, and two gears, each corresponding to one another. The two transmission members are respectively disposed on opposite sides of the sliding member, the two racks are respectively disposed on the corresponding transmission members, and the two gears respectively mesh with the corresponding racks.

[0011] In some embodiments, the gear portion is disposed at one end of the handle, and the end of the handle away from the gear portion has a grip portion. The rotation axis of the handle is located between the grip portion and the gear portion, and the distance between the grip portion and the rotation axis of the handle is greater than the distance between the gear portion and the rotation axis of the handle.

[0012] Based on the first aspect, the door handle structure of this application embodiment includes a support component, a swing arm, a moving component, and a handle. When the door lock is opened, the handle is rotated, the gear and rack mesh, driving the moving component to move. The moving component then drives the swing arm to swing, which in turn moves the cable, thereby opening the door lock. Because the meshing of the gear and rack is smoother, the smoothness of opening the door lock is improved. Furthermore, because the distance between the first end and the rotation axis of the swing arm is smaller than the distance between the second end and the rotation axis of the swing arm, it requires less effort to open the door lock. Thus, the door handle structure of this application embodiment improves the smoothness of opening the door lock and requires less effort, thereby enhancing the user experience.

[0022] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that allows communication between the two components; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0024] Please see Figure 1 This application provides a door handle structure 100 for opening a door lock (not shown) of a car door (not shown). The door handle structure 100 can be an inner opening handle structure or an outer opening handle structure of the car door. For ease of understanding, this application uses the door handle structure 100 as an example of an inner opening handle structure of the car door. Obviously, this is not a limitation of this application.

[0025] Please see Figure 1 In this embodiment, the door handle structure 100 includes a support component 10, a swing arm 20, a moving component 30, and a handle 40.

[0026] Support assembly 10 is used to connect to the interior trim panel (not shown) of the door. A swing arm 20 is rotatably mounted on support assembly 10. The swing arm 20 has a first end 21 and a second end 22 disposed opposite each other. The rotation axis L1 of the swing arm 20 is located between the first end 21 and the second end 22. The distance between the first end 21 and the rotation axis L1 of the swing arm 20 is less than the distance between the second end 22 and the rotation axis L1 of the swing arm 20. The first end 21 is configured to connect to the door lock cable 60.

[0027] The movable component 30 is slidably disposed on the support component 10 and movably connected to the second end 22. The movable component 30 has a rack portion 33, the extending direction of which is the same as the sliding direction of the movable component 30. The handle 40 is rotatably disposed on the support component 10. The handle 40 has a gear portion 41, which meshes with the rack portion 33.

[0028] When the door handle structure 100 of this embodiment is used to unlock the door, the handle 40 is rotated, the gear part 41 meshes with the rack part 33, driving the moving component 30 to move. The moving component 30 drives the swing arm 20 to swing, and the swing arm 20 drives the pull cable 60 to move, thereby unlocking the door. Because the meshing transmission between the gear part 41 and the rack part 33 is smoother, the smoothness of unlocking the door is improved. Furthermore, because the distance between the first end 21 and the rotation axis L1 of the swing arm 20 is smaller than the distance between the second end 22 and the rotation axis L1 of the swing arm 20, it is easier to unlock the door. Thus, the door handle structure 100 of this embodiment improves the smoothness of unlocking the door and requires less effort, improving the user experience.

[0029] In this embodiment, the gear part 41 is a sector gear, which facilitates fixing the gear part 41 to the handle 40 and helps save installation space. In some other embodiments, the gear part 41 may also be a circular gear, and this application does not specifically limit this.

[0030] In this embodiment, the gear part 41 is fixedly connected to the handle 40. In some other embodiments, the gear part 41 and the handle 40 may also be an integral structure, and this application does not specifically limit this.

[0031] Please refer to the following: Figure 2 In this embodiment, the support assembly 10 includes an assembly 11, a support member 12, and a rotating shaft 13. The adjacent side walls of the assembly 11 are respectively provided with an assembly groove 111 and a clearance opening 112. The clearance opening 112 communicates with the assembly groove 111. The support member 12 is disposed in the assembly groove 111 and protrudes from it. The moving assembly 30 is slidably disposed on the portion of the support member 12 protruding from the assembly groove 111. The handle 40 is rotatably disposed on the portion of the support member 12 protruding from the assembly groove 111 and located on the side of the moving assembly 30 opposite to the assembly groove 111. The rotating shaft 13 passes through the swing arm 20 and is located at the clearance opening 112. Both ends of the rotating shaft 13 are respectively connected to the side walls of the assembly groove 111. The axis of the rotating shaft 13 is collinear with the rotation axis L1 of the swing arm 20.

[0032] This design makes the door handle structure 100 more compact, which helps to reduce the size of the door handle structure 100.

[0033] In this embodiment, the support component 10 further includes a first rivet 14, and the support member 12 is connected to the assembly 11 through the first rivet 14, thereby improving the convenience of fixing the support member 12.

[0034] In this embodiment, the first end 21 is provided with a slot 211, which is configured to connect with the pull cable 60. This improves the ease of connecting the swing arm 20 to the pull cable 60.

[0035] In this embodiment, the second end 22 has a movable elongated hole 2211, and the extension direction of the movable elongated hole 2211 is perpendicular to the extension direction of the rotation axis L1 of the swing arm 20. The door handle structure 100 also includes a movable shaft 50, the extension direction of the movable shaft 50 is parallel to the extension direction of the rotation axis L1 of the swing arm 20, and the movable shaft 50 is inserted into the movable elongated hole 2211 and connected to the moving component 30.

[0036] When the movable component 30 drives the swing arm 20 to swing, the movable shaft 50 slides in the movable elongated hole 2211 according to the swing angle of the swing arm 20, thereby expanding the swing range of the movable component 30 driving the swing arm 20 and reducing the probability of jamming between the movable component 30 and the swing arm 20.

[0037] In this embodiment, the first end 21 has two limiting plates 221, which are spaced apart along the extension direction of the movable shaft 50. There are two movable elongated holes 2211, which are respectively opened on the two limiting plates 221 and are arranged opposite to each other. The moving component 30 extends between the two limiting plates 221, and the movable shaft 50 passes through the part of the moving component 30 that extends between the two limiting plates 221. Both ends of the movable shaft 50 are respectively inserted into the two movable elongated holes 2211.

[0038] When the moving component 30 drives the swing arm 20 to swing, the two limiting plates 221 stop and limit the moving component 30 from both sides, reducing the probability of the moving component 30 deviating relative to the swing arm 20. At the same time, the movable shaft 50 applies force to the inner wall of the two movable elongated holes 2211 to make the swing arm 20 swing, reducing the probability of the swing arm 20 wobbling. In this way, by setting two limiting plates 221 and two movable elongated holes 2211, the accuracy and stability of the swing arm 20 driven by the moving component 30 are improved.

[0039] In this embodiment, the swing arm 20 is provided with multiple reinforcing ribs 23, which are arranged radially around the rotation axis L1 of the swing arm 20. This improves the structural strength of the swing arm 20, thereby increasing the service life of the door handle structure 100.

[0040] In this embodiment, the moving component 30 includes a slider 31 and a transmission component 32. The slider 31 is slidably disposed in the support component 10, and the transmission component 32 is connected to the slider 31. A rack portion 33 is disposed in the transmission component 32. Thus, the moving component 30 has a simple structure, and the slider 31 is partially hidden in the support component 10, which improves the overall compactness of the door handle structure 100.

[0041] In this embodiment, the portion of the support member 12 that protrudes from the assembly groove 111 is provided with a sliding hole 121. The sliding hole 121 extends toward the swing arm 20, and the sliding member 31 passes through the sliding hole 121, thereby improving the convenience of installing the sliding member 31 and improving the accuracy of the sliding member 31 sliding on the support member 12.

[0042] In some other embodiments, the transmission member 32 may also be slidably connected to the support member 12 via a slide rail (not shown), and this application embodiment does not specifically limit this.

[0043] In this embodiment, there are two transmission members 32, racks 33 and gears 41, which correspond to each other. The two transmission members 32 are respectively located on opposite sides of the sliding member 31, the two racks 33 are respectively located on the corresponding transmission members 32, and the two gears 41 mesh with the corresponding racks 33.

[0044] When the handle 40 moves the moving component 30, the handle 40 simultaneously applies force to the two transmission components 32 through the meshing of the two gear parts 41 and the two rack parts 33. The two transmission components 32 simultaneously drive the sliding member 31 to move, and the sliding member 31 drives the swing arm 20 to swing through the movable shaft 50. Because the two gear parts 41 mesh with the two rack parts 33 respectively, the force applied from both sides is more stable and smooth, thereby improving the stability and smoothness of the door handle structure 100 in opening the door lock.

[0045] In this embodiment, the two transmission components 32 are symmetrically arranged with respect to the sliding component 31. When the handle 40 drives the moving component 30 to move, the force on both sides of the sliding component 31 is relatively uniform, thereby further improving the stability and smoothness of the door handle structure 100 in opening the door lock.

[0046] In this embodiment, the ends of the sliding member 31 and the two transmission members 32 near the swing arm 20 extend between the two limiting plates 221. The movable shaft 50 passes through the portion of the sliding member 31 and the two transmission members 32 extending between the two limiting plates 221, thereby connecting the ends of the sliding member 31 and the two transmission members 32 near the swing arm 20. The ends of the sliding member 31 and the two transmission members 32 away from the swing arm 20 are connected by the second rivet 34. This improves the convenience of connecting the sliding member 31 and the two transmission members 32.

[0047] In some other embodiments, the sliding member 31 and the two transmission members 32 may be connected by bolts or welding, and only one end of the sliding member 31 near the swing arm 20 may extend between the two limiting plates 221, with the movable shaft 50 passing through the part of the sliding member 31 that extends between the two limiting plates 221. This application does not specifically limit this aspect.

[0048] In this embodiment, the gear part 41 is provided at one end of the handle 40, and the end of the handle 40 away from the gear part 41 has a grip part 42. The rotation axis L2 of the handle 40 is located between the grip part 42 and the gear part 41. The distance between the grip part 42 and the rotation axis L2 of the handle 40 is greater than the distance between the gear part 41 and the rotation axis L2 of the handle 40.

[0049] In this way, it is easier to move the moving component 30 by turning the handle 40, which makes it easier to open the door lock and improves the user experience.

[0050] In this embodiment, the rotation axis L2 of the handle 40 is parallel to the rotation axis L1 of the swing arm 20, thereby improving the efficiency of the force applied to the handle 40 being transmitted to the swing arm 20, and thus making it easier to open the door lock using the door handle structure 100.

[0051] In this embodiment, the handle 40 adopts an aircraft lever-style structure, which is more comfortable for the user to hold, makes the door lock opening method more novel and more ceremonial, thereby further improving the user experience.

[0052] In summary, the door handle structure 100 of this application embodiment comprises a support assembly 10, a swing arm 20, a moving assembly 30, and a handle 40. When the door lock is opened, the handle 40 is rotated, the gear 41 meshes with the rack 33, driving the moving assembly 30 to move. The moving assembly 30 then drives the swing arm 20 to swing, which in turn drives the cable 60 to move, thereby opening the door lock. Because the meshing and transmission between the gear 41 and the rack 33 is smoother, the smoothness of opening the door lock is improved. Furthermore, because the distance between the first end 21 and the rotation axis L1 of the swing arm 20 is smaller than the distance between the second end 22 and the rotation axis L1 of the swing arm 20, it requires less effort to open the door lock. Thus, the door handle structure 100 of this application embodiment improves the smoothness of opening the door lock and requires less effort, thereby enhancing the user experience.

[0053] This application also provides a door assembly (not shown in the figure), including the door handle structure 100 as described in the above embodiments.

[0054] The door assembly of this application embodiment improves the smoothness of opening the door lock and makes it less strenuous by setting the door handle structure 100 described above, thereby improving the user experience.

[0055] This application also provides a vehicle (not shown) including a door assembly as described in the above embodiments.

[0056] The vehicle in this embodiment improves the smoothness of opening the door lock and makes it less strenuous by incorporating a door assembly including the aforementioned door handle structure 100, thereby enhancing the user experience.

Therefore, the embodiments should be regarded in all respects as exemplary and not restrictive, and the scope of this application is defined by the appended claims rather than the foregoing description.
