In this way, the door handle provided in the embodiments of the present application effectively seals the internal structure of the door handle by setting the sealing assembly, solves the airtightness requirements of the door handle to different degrees, and improves the problems of air leakage, wind noise, etc. when the vehicle is driving.

[0056] A second aspect of the present application provides a vehicle door, which is provided with a door handle as described above.

[0057] A third aspect of the present application provides a vehicle, comprising a vehicle body and the above-mentioned vehicle door, wherein the vehicle body and the vehicle door are connected.

[0058] The following will describe the implementation methods of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.

[0059] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0060] The embodiment of the present application provides a door handle, a door and a vehicle. By setting a sealing component, the internal structure of the door handle is effectively sealed, the airtightness requirements of the door handle to varying degrees are met, and the problems of air leakage and wind noise when the vehicle is driving are improved. The specific structure of a door handle, a door and a vehicle provided in the embodiment of the present application is introduced below in conjunction with the accompanying drawings.

[0061] refer to Figure 1In a first aspect, an embodiment of the present application provides a vehicle door handle 100. The vehicle door handle 100 may include a base 200, a handle assembly 300, and a sealing assembly 400. In an embodiment of the present application, the base 200 may be disposed in a vehicle door 500, and the handle assembly 300 may be rotatably connected to the base 200. In a possible implementation, the sealing assembly 400 may include a first sealing structure 410 and a second sealing structure 420, wherein the first sealing structure 410 may be sealed at a rotational connection between the handle assembly 300 and the base 200, and the second sealing structure 420 may be sealed at the handle assembly 300, and the second sealing structure 420 may be disposed opposite to the rotational connection between the handle assembly 300 and the base 200.

[0062] It can be understood that the first sealing structure 410 and the second sealing structure 420 can be sealed at different positions of the handle assembly 300 respectively, without affecting the rotation of the door handle 100, thereby reducing the airflow channel in which the door handle 100 moves, thereby effectively improving the airtightness of the door handle 100, reducing airtightness problems such as wind noise, and further improving the quality and performance of the entire vehicle.

[0063] Continue to refer Figure 1 On the basis of the above embodiment, further, the handle assembly 300 may include: a handle frame 310 and a handle cover 320. The handle frame 310 may be connected to the handle cover 320. In the embodiment of the present application, Figure 2 As shown, the handle frame 310 can be rotatably connected to the base 200 via the rotating shaft 330. In a possible embodiment, the handle frame 310 can be provided with a first shaft hole 313, and the base 200 can be provided with a second shaft hole 220. The first shaft hole 313 and the second shaft hole 220 are arranged correspondingly. In this way, the rotating shaft 330 can be sequentially passed through the first shaft hole 313 and the second shaft hole 220, so that the handle frame 310 is rotatably connected to the base 200 via the rotating shaft 330. In addition, a return torsion spring (not shown in the figure) can be wound around the rotating shaft 330, so that the handle frame 310 is in a return closed state when not rotating.

[0064] Continue to refer Figure 1 as well as Figure 2On the basis of the above-mentioned embodiment, the first sealing structure 410 can seal at least part of the contact surface between the handle frame 310 and the base 200. When the handle frame 310 is in a closed state, the handle frame 310 and the base 200 are in contact. However, in actual working conditions, there may be a gap between the handle frame 310 and the base 200, and the first sealing structure 410 can be located on the contact surface between the handle frame 310 and the base 200, thereby playing a good sealing role. In addition, the second sealing structure 420 can seal at the connection between the handle frame 310 and the handle cover 320. In actual working conditions, there may also be a gap between the handle frame 310 and the handle cover 320, and the second sealing structure 420 can be located at the connection between the handle frame 310 and the handle cover 320, thereby playing a good sealing role.

[0065] refer to Figure 3 On the basis of the above embodiment, further, the handle frame 310 may include: a main body 311 and a swing arm 312. The main body 311 may be matched with the base 200, and the swing arm 312 may be protrudingly arranged on the main body 311. It can be understood that one side of the main body 311 may be matched with the base 200, and the other side of the main body 311 may be matched with the handle cover 320. In a possible implementation, the main body 311 may have a protruding portion 3111 on the side facing the base 200, and the swing arm 312 may be arranged on the protruding portion 3111. The first shaft hole 313 may be opened on the swing arm 312, so that the swing arm 312 can rotate around the rotating shaft 330.

[0066] refer to Figure 3 , Figure 4 as well as Figure 5 On the basis of the above embodiment, a groove 210 may be provided on the side of the base 200 facing the handle frame 310. The groove 210 may be inserted into the swing arm 312, and the groove 210 and the swing arm 312 are arranged correspondingly. It can be understood that when the handle frame 310 is in a rotating state, the swing arm 312 may be rotated in the groove 210 through the rotating shaft 330. When the handle frame 310 is in a closed state, the swing arm 312 may be rotated back to the groove 210 of the base 200, so that the side wall of the swing arm 312 is in contact with the side wall of the groove 210.

[0067] Continue to refer Figure 3 On the basis of the above embodiment, in one possible implementation, the number of the swing arms 312 may be several, and the embodiment of the present application does not limit the number of the swing arms 312. Several swing arms 312 may be sequentially spaced apart on the main body 311 in the first direction. In the embodiment of the present application, two swing arms 312 are used as an example.

[0068] Continue to refer Figure 5 , based on the above embodiment, in one possible implementation, the number of grooves 210 may also be several, and the embodiment of the present application does not limit the number of grooves 210. It can be understood that the number of grooves 210 should be the same as the number of swing arms 312. Several grooves 210 can be arranged in the base 200 in sequence in the first direction, and several swing arms 312 are correspondingly arranged in the several grooves 210. In the embodiment of the present application, the number of grooves 210 is two for example. Among them, two grooves 210 can be arranged corresponding to two swing arms 312.

[0069] It should be noted that, for the convenience of description, in the embodiment of the present application, the first direction may be the length direction of the door handle 100, that is, Figure 3 The x direction in .

[0070] Continue to refer Figure 5 On the basis of the above embodiment, the first sealing structure 410 can be sealed between the side wall of the swing arm 312 and the side wall of the groove 210. In a possible implementation, the first sealing structure 410 can be sealed between the outer side wall of the swing arm 312 and the inner side wall 211 of the groove 210. It can be understood that in actual working conditions, there may be a gap between the outer side wall of the swing arm 312 and the inner side wall 211 of the groove 210, and the first sealing structure 410 can be located in the gap between the swing arm 312 and the groove 210, thereby playing a good sealing role.

[0071] Continue to refer Figure 3 as well as Figure 4 On the basis of the above embodiment, the first sealing structure 410 may further include: a first sealing rib 411. The first sealing rib 411 may be arranged on the outer side wall of the swing arm 312 in the first direction.

[0072] Continue to refer Figure 5On the basis of the above embodiment, further, the first sealing structure 410 may also include: a second sealing rib 412. Among them, the base 200 may be formed with two inner side walls 211 arranged opposite to each other after the groove 210 is formed, and the second sealing rib 412 may be arranged on the inner side wall 211. In the embodiment of the present application, the second sealing rib 412 and the first sealing rib 411 abut against each other to achieve sealing. In this way, through the sealing abutment of the first sealing rib 411 and the second sealing rib 412, the first sealing structure 410 is sealed in the gap between the swing arm 312 and the groove 210, thereby playing a good sealing role at the rotation connection between the handle assembly 300 and the base 200.

[0073] Continue to refer Figure 3 , Figure 4 as well as Figure 5 On the basis of the above embodiment, in a possible implementation manner, in each corresponding swing arm 312 and groove 210, there may be two first sealing ribs 411, and there may also be two second sealing ribs 412. The two first sealing ribs 411 may be respectively arranged on the two outer side walls of the swing arm 312 in the first direction, and the two second sealing ribs 412 may be respectively arranged on the two opposite inner side walls 211 of the groove 210. It can be understood that the two first sealing ribs 411 may be respectively and correspondingly abutted with the two second sealing ribs 412.

[0074] Of course, in some other embodiments, the number of the first sealing rib 411 and the second sealing rib 412 can be multiple, and the position of the first sealing rib 411 and the second sealing rib 412 can also be any position between the swing arm 312 and the groove 210, and the embodiments of the present application are not limited here.

In one possible implementation, the base 200 may further include a bottom wall 212 after the groove 210 is provided, and the bottom wall 212 may be located between the two inner side walls 211, so that the bottom wall 212 and the two inner side walls 211 together form the groove 210. The third sealing rib 413 may be provided on the bottom wall 212. It is understandable that the third sealing rib 413 may directly fit the side wall of the swing arm 312, so that the third sealing rib 413 and the swing arm 312 are in sealed contact.

[0076] Continue to refer Figure 4 Based on the above embodiment, in another possible implementation manner, the first sealing structure 410 may further include: a fourth sealing rib 414. Figure 5From this perspective, the fourth sealing rib 414 can be disposed on the side of the swing arm 312 facing the bottom wall 212. It can be understood that the fourth sealing rib 414 can cooperate with the third sealing rib 413 so that the fourth sealing rib 414 and the third sealing rib 413 can achieve sealing contact.

[0077] Based on the above embodiment, the first sealing rib 411 and the fourth sealing rib 414 located on the outer wall of the swing arm 312 can be injection molded onto the handle frame 310 through an injection molding process, so that the first sealing rib 411 and the fourth sealing rib 414 and the handle frame 310 are integrally formed.

[0078] Based on the above embodiments, the second sealing rib 412 located on the inner wall 211 of the groove 210 and the third sealing rib 413 located on the bottom wall 212 of the groove 210 can be injection molded on the base 200 by secondary injection molding, so that the second sealing rib 412 and the third sealing rib 413 are integrally formed with the base 200.

[0079] Continue to refer Figure 2 On the basis of the above embodiment, in a possible implementation manner, the side of the swing arm 312 facing the handle cover 320 may be an abutting surface 3121, and the second sealing structure 420 may achieve sealing abutment with the abutting surface 3121.
