[0054] As described in the background, in the existing vehicle door handle, due to the air flow channel from outside to inside when pulling the door handle, the internal structure of the handle cannot be effectively sealed, and the current vehicle door handle has different degrees of air tightness problems, causing air leakage, wind noise and other problems when the vehicle is running, and the waterproof and dustproof performance of the door handle needs to be improved.

[0055] To solve the above technical problems, the embodiment of the present application provides a vehicle door handle, a vehicle door and a vehicle. The vehicle door handle provided by the first aspect of the present application comprises a base, a handle assembly and a sealing assembly. The base is arranged in the vehicle door, and the handle assembly is rotatably connected to the base. The sealing assembly comprises a first sealing structure and a second sealing structure. The first sealing structure is sealed at the rotating connection between the handle assembly and the base, and the second sealing structure is sealed at the handle assembly and arranged opposite to the rotating connection between the handle assembly and the base. In this way, the vehicle door handle provided by the embodiment of the present application effectively seals the internal structure of the vehicle door handle by arranging the sealing assembly, solves the air tightness requirement of the vehicle door handle to different degrees, and improves the problems of air leakage and wind noise during driving of the vehicle.

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

[0057] The third aspect of the present application provides a vehicle, which comprises a vehicle body and the vehicle door as described above, and the vehicle body and the vehicle door are connected.

[0058] The embodiments of the present application will be described below with reference to the drawings and preferred embodiments, and other advantages and effects of the present application can be easily understood by those skilled in the art from the disclosure in the specification. The present application can also be implemented or applied by means of other different specific embodiments, and various modifications or changes can be made to the details in the specification 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, but not for limiting the protection scope of the present application.

[0059] It should be noted that the drawings provided in the following embodiments only schematically illustrate the basic concept of the present application, and only the components related to the present application are shown in the drawings, but not drawn according to the number, shape and size of the components in actual implementation. The shape, number and proportion of each component in actual implementation can be randomly changed, and the layout pattern of the components can be more complex.

[0060] The embodiment of the present application provides a vehicle door handle, a vehicle door and a vehicle. By arranging the sealing assembly, the internal structure of the vehicle door handle is effectively sealed, the air tightness requirement of the vehicle door handle to different degrees is solved, and the problems of air leakage and wind noise during driving of the vehicle are improved. The specific structure of the vehicle door handle, the vehicle door and the vehicle provided by the embodiment of the present application will be introduced below with reference to the drawings.

[0061] Reference Figure 1This application provides a door handle 100 in a first aspect. The door handle 100 may include a base 200, a handle assembly 300, and a sealing assembly 400. In this embodiment, the base 200 may be disposed in a door 500, and the handle assembly 300 may be rotatably connected to the base 200. In one 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 seal the rotatable connection between the handle assembly 300 and the base 200, and the second sealing structure 420 may seal the handle assembly 300, and the second sealing structure 420 may be disposed opposite to the rotatable connection between the handle assembly 300 and the base 200.

[0062] It is understandable that the first sealing structure 410 and the second sealing structure 420 can seal at different positions of the handle assembly 300, thereby reducing the airflow channel of the door handle 100 without affecting its rotation, thus effectively improving the airtightness of the door handle 100, reducing airtightness issues such as wind noise, and ultimately improving the overall quality and performance of the vehicle.

[0063] Continue to refer to Figure 1 Based on the above embodiments, the handle assembly 300 may further include a handle frame 310 and a handle cover 320. The handle frame 310 can be connected to the handle cover 320. In the embodiments of this application, as... Figure 2 As shown, the handle frame 310 can be rotatably connected to the base 200 via a pivot 330. In one possible embodiment, the handle frame 310 may have a first pivot hole 313, while the base 200 may have a second pivot hole 220. The first pivot hole 313 and the second pivot hole 220 are correspondingly arranged. In this way, the pivot 330 can pass through the first pivot hole 313 and the second pivot hole 220 in sequence, thereby enabling the handle frame 310 to be rotatably connected to the base 200 via the pivot 330. In addition, a return torsion spring (not shown in the figure) may be wound around the pivot 330, so that the handle frame 310 is in a returned closed state when not rotating.

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

[0065] Reference Figure 3 On the basis of the above-mentioned embodiments, further, the handle skeleton 310 can include a main body part 311 and a swing arm 312. The main body part 311 can be matched with the base 200, and the swing arm 312 can be protrudingly arranged on the main body part 311. It can be understood that one side of the main body part 311 can be arranged in cooperation with the base 200, and the other side of the main body part 311 can be arranged in cooperation with the handle cover 320. In a possible implementation manner, the side of the main body part 311 facing the base 200 can have a protruding part 3111, and the swing arm 312 can be arranged on the protruding part 3111. The first shaft hole 313 can be arranged on the swing arm 312, so that the swing arm 312 can rotate around the rotating shaft 330.

[0066] Reference Figure 3 , Figure 4 and Figure 5 On the basis of the above-mentioned embodiments, the side of the base 200 facing the handle skeleton 310 can be provided with a recess 210. The recess 210 can be arranged in correspondence with the swing arm 312, and the swing arm 312 can be inserted into the recess 210. It can be understood that when the handle skeleton 310 is in the rotating state, the swing arm 312 can rotate in the recess 210 through the rotating shaft 330. When the handle skeleton 310 is in the closed state, the swing arm 312 can rotate back to the recess 210 of the base 200, so that the side wall of the swing arm 312 is in contact with the side wall of the recess 210.

[0067] Continuing to refer to Figure 3 On the basis of the above-mentioned embodiments, in a possible implementation manner, the number of the swing arms 312 can be several, and the number of the swing arms 312 is not limited in the embodiments of the present application. The several swing arms 312 can be arranged in sequence and at intervals in the first direction on the main body part 311. In the embodiments of the present application, the number of the swing arms 312 is taken as two for example.

[0068] Continue to refer to Figure 5 Based on the above embodiments, in one possible implementation, the number of grooves 210 can also be several. This application embodiment does not limit the number of grooves 210. It is understood that the number of grooves 210 should be the same as the number of swing arms 312. Several grooves 210 can be sequentially and spaced apart on the base 200 in the first direction, and several swing arms 312 are correspondingly disposed within several grooves 210. In this application embodiment, two grooves 210 are used as an example. Two grooves 210 can be correspondingly disposed with two swing arms 312.

[0069] It should be noted that, for ease of description, in this embodiment, the first direction can be the length direction of the door handle 100, i.e. Figure 3 The x-direction in the middle.

[0070] Continue to refer to Figure 5 Based on the above embodiments, the first sealing structure 410 can seal between the side wall of the swing arm 312 and the side wall of the groove 210. In one possible implementation, the first sealing structure 410 can seal between the outer side wall of the swing arm 312 and the inner side wall 211 of the groove 210. It is 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 achieving a good sealing effect.

[0071] Continue to refer to Figure 3 as well as Figure 4 Based on the above embodiments, the first sealing structure 410 may further include a first sealing rib 411. The first sealing rib 411 may be disposed on the outer side wall of the swing arm 312 in the first direction. In one possible implementation, the first sealing rib 411 may be fitted along the edge of the swing arm 312 toward the handle cover 320, thereby adapting the shape of the first sealing rib 411 to the outer edge of the swing arm 312.

[0072] Continue to refer to Figure 5On the basis of the above-mentioned embodiments, the first sealing structure 410 can further include a second sealing rib 412. The base 200 can be provided with two oppositely arranged inner side walls 211 after the groove 210 is formed, and the second sealing rib 412 can be arranged on the inner side walls 211. In the embodiments of the present application, the second sealing rib 412 abuts against the first sealing rib 411, thereby achieving sealing. In this way, the abutment of the first sealing rib 411 and the second sealing rib 412 allows the first sealing structure 410 to be sealed in the gap between the swing arm 312 and the groove 210, thereby achieving good sealing at the rotating connection between the handle assembly 300 and the base 200.

[0073] With reference to the above-mentioned embodiments, Figure 3 , Figure 4 and Figure 5 , on the basis of the above-mentioned embodiments, in one possible implementation, two first sealing ribs 411 and two second sealing ribs 412 can be arranged in each of the corresponding swing arm 312 and groove 210. The two first sealing ribs 411 can be arranged on the two outer side walls of the swing arm 312 in the first direction, and the two second sealing ribs 412 can be arranged on the two oppositely arranged inner side walls 211 of the groove 210. It can be understood that the two first sealing ribs 411 can abut against the two second sealing ribs 412 for sealing.

[0074] Of course, in some other embodiments, the number of the first sealing ribs 411 and the second sealing ribs 412 can be several, and the positions of the first sealing ribs 411 and the second sealing ribs 412 can be any positions between the swing arm 312 and the groove 210, which are not limited in the embodiments of the present application.

[0075] With reference to the above-mentioned embodiments, Figure 5 , on the basis of the above-mentioned embodiments, the first sealing structure 410 can further include a third sealing rib 413. In one possible implementation, the base 200 can be provided with a bottom wall 212 after the groove 210 is formed. The bottom wall 212 can 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 can be arranged on the bottom wall 212. It can be understood that the third sealing rib 413 can directly abut against the side wall of the swing arm 312, so that the third sealing rib 413 abuts against the swing arm 312 for sealing.

[0076] With reference to the above-mentioned embodiments, Figure 4 , on the basis of the above-mentioned embodiments, in another possible implementation, the first sealing structure 410 can further include a fourth sealing rib 414. In combination with Figure 5The fourth sealing rib 414 can be arranged 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 achieve sealing abutment.

[0077] On the basis of the above embodiment, the first sealing rib 411 and the fourth sealing rib 414 on the outer side wall of the swing arm 312 can be injection molded on the handle skeleton 310 by an injection molding process, so that the first sealing rib 411 and the fourth sealing rib 414 are integrally formed with the handle skeleton 310.

[0078] On the basis of the above embodiment, the second sealing rib 412 on the inner side wall 211 of the recess 210 and the third sealing rib 413 on the bottom wall 212 of the recess 210 can be injection molded on the base 200 by a secondary injection molding process, so that the second sealing rib 412 and the third sealing rib 413 are integrally formed with the base 200.

[0079] With reference to Figure 2 On the basis of the above embodiment, in a possible implementation, the side of the swing arm 312 facing the handle cover 320 can be the abutment surface 3121, and the second sealing structure 420 can achieve sealing abutment with the abutment surface 3121. In this way, one end of the second sealing structure 420 can be connected to the abutment surface 3121, and the other end of the second sealing structure 420 can be connected to the handle cover 320, so that the second sealing structure 420 is sealed to the handle assembly 300. It can be understood that the second sealing structure 420 is connected to the abutment surface 3121 on the swing arm 312, so that the second sealing structure 420 can be arranged opposite the connection between the swing arm 312 and the recess 210.

[0080] With reference to Figure 6 and Figure 7 On the basis of the above embodiment, the second sealing structure 420 can be provided with a fifth sealing rib 421 on the side facing the swing arm 312.

In the embodiment of the present application, the second sealing structure 420 can abut against the abutment surface 3121 on the swing arm 312 through the fifth sealing rib 421, so as to achieve sealing abutment between the second sealing structure 420 and the abutment surface 3121.

[0081] With reference to Figure 7Based on the above embodiments, in one possible implementation, the fifth sealing rib 421 may include a first extension 4211, a second extension 4212, and a third extension 4213. The first extension 4211, the second extension 4212, and the third extension 4213 may be arranged sequentially along the outer periphery of the second sealing structure 420, so that the first extension 4211, the second extension 4212, and the third extension 4213 surround the fifth sealing rib 421.

[0082] Continue to refer to Figure 7 Based on the above embodiments, the first extension segment 4211 and the third extension segment 4213 can be arranged opposite to each other. One of the first extension segment 4211 and the third extension segment 4213 can abut against one end of the second extension segment 4212, while the other of the first extension segment 4211 and the third extension segment 4213 can be spaced apart from the other end of the second extension segment 4212. In one possible implementation, the first extension segment 4211 can abut against one end of the second extension segment 4212, while the third extension segment 4213 can be spaced apart from the other end of the second extension segment 4212. Alternatively, in another possible implementation, the third extension segment 4213 can abut against one end of the second extension segment 4212, while the first extension segment 4211 can be spaced apart from the other end of the second extension segment 4212. In this way, the first extension section 4211, the second extension section 4212 and the third extension section 4213 can cooperate with the abutment surface 3121 of the swing arm 312 to form a seal. The entire fifth sealing rib 421 avoids large-area contact between the second sealing structure 420 and the abutment surface 3121, preventing abnormal noise between the two.
