[0002] The existing actuating assembly includes an upper shell, a lower shell, a drive shaft and a seal. The upper shell and the lower shell are arranged on both sides of the drive shaft and wrap the drive shaft. The drive shaft is generally cylindrical. The seal is sleeved on the outside of the drive shaft and abuts against the upper shell and the lower shell to form a seal. The drive shaft can move relative to the upper shell and the lower shell to achieve actuation.

[0003] The existing actuating assembly is arranged in a vehicle handle. In particular, it is arranged in a concealed vehicle handle. When the door is closed, the vehicle handle is flush with the outer surface of the vehicle panel. When the door needs to be opened, the actuating assembly pushes the vehicle handle to move, so as to protrude from the outer surface of the vehicle panel, so that the user's hand can hold and pull the vehicle handle to open the door. CONTENT OF THE INVENTION

[0004] The inventor of the present application has found through in-depth research that the upper shell, the lower shell and the seal of the actuating assembly in the prior art are prone to leakage. Specifically, in the field of vehicle handles, especially concealed door handles, the shell is formed by connecting the substantially symmetrical upper half shell and the lower half shell, the connecting seam of the upper half shell and the lower half shell is substantially located in the same plane, the seal is arranged between the upper half shell and the lower half shell, and the seal is arranged perpendicular to the plane. Since the drive shaft translates and rotates relative to the seal, the drive shaft exerts a large force on the seal, which causes the seal to deform outward as a whole, causing the connecting seam to crack and leading to failure of the seal.

[0005] To solve the above technical problems, the present application provides an actuating assembly, which includes a shell, a first sealing shell, a second sealing shell and a seal. The shell defines a shell cavity, and the shell cavity has an output opening. The first sealing shell is arranged in the output opening and connected with the shell. The second sealing shell is connected with the first sealing shell and forms a sealing cavity. The seal is arranged in the sealing cavity.

[0006] According to some specific embodiments, the first sealing shell is provided with a first connecting structure, the second sealing shell is provided with a second connecting structure, and the first connecting structure can cooperate with the second connecting structure to connect the first sealing shell and the second sealing shell.

[0007] According to some embodiments, the first connecting structure comprises at least one connecting recess provided on the first sealed housing. The second connecting structure comprises at least one connecting protrusion provided on the second sealed housing. The connecting protrusion is capable of entering the connecting recess in a first direction.

[0008] According to some embodiments, the first connecting structure and the second connecting structure connect the first sealed housing and the second sealed housing together through interference fit.

[0009] According to some embodiments, the first sealed housing is provided with a first guiding structure, and the housing is provided with a second guiding structure. The first guiding structure and the second guiding structure are capable of guiding the first sealed housing to move relative to the housing in a first direction.

[0010] According to some embodiments, the first guiding structure comprises at least one guiding protrusion provided on the first sealed housing. The second guiding structure comprises at least one guiding recess provided on the housing. The guiding protrusion is capable of entering the guiding recess in a first direction.

[0011] According to some embodiments, the housing and the first sealed housing are connected together through welding. The first sealed housing is provided with a groove for accommodating a portion of the housing.

[0012] According to some embodiments, the actuating assembly further comprises a drive shaft. A portion of the drive shaft is accommodated in the housing cavity and is capable of moving relative to the housing. The drive shaft is capable of passing through the first sealed housing, the second sealed housing and the sealing member. Opposite sides of the sealing member abut against the drive shaft and the first sealed housing respectively to form a seal.

[0013] According to some embodiments, the sealing member is annular, and a cross section of the sealing member is X-shaped.

[0014] According to some embodiments, the drive shaft is provided with a drive guide thread. An inner wall of the housing cavity is provided with a housing guide thread. The drive guide thread is capable of cooperating with the housing guide thread. The housing guide thread is formed integrally with the housing.

[0015] According to some embodiments, the output opening is defined by an integral structure.

[0040] Various embodiments of the present application will be described hereinafter with reference to the accompanying drawings. It is to be understood that the same or like components are designated by the same or like reference numerals throughout the accompanying drawings.

[0041] The "first direction" of the present application refers to the length direction of the drive shaft.

[0042] The "second direction" of the present application refers to the thickness direction of the housing which is substantially perpendicular to the length direction of the drive shaft.

[0043] Figure 1 is a perspective view of the actuation assembly of the present application. As Figure 1As shown, the actuating assembly includes a housing 102, a cover plate 104, a sealing assembly 106 and a drive shaft 108. The housing 102 defines a housing cavity. The housing cavity has an output opening and a mounting opening. The cover plate 104 is arranged at the mounting opening and connected with the housing 102 to seal the mounting opening. The cover plate 104 is substantially a flat plate. A portion of the drive shaft 108 is accommodated in the housing cavity and the drive shaft 108 extends out of the housing 102 through the output opening. The drive shaft 108 is movable along a first direction X and rotatable about the first direction X relative to the housing 102. The first direction X is a length direction of the drive shaft 108. The sealing assembly 106 is arranged in the output opening and between the drive shaft 108 and the housing 102. The sealing assembly 106 is connected with the housing 102 to seal the output opening and the drive shaft 108.

[0044] Figure 2 is Figure 1 An exploded view of the actuating assembly of the present application is shown. As Figure 2 shown, the output opening of the housing 102 faces the first direction X. The mounting opening of the housing 102 faces a second direction Y which is substantially perpendicular to the first direction X. The second direction Y is a thickness direction of the housing 102. The drive shaft 108 is arranged in the housing cavity of the housing 102. The drive shaft 108 includes a guide portion 202, a drive portion 204 and a sealing portion 206. The guide portion 202 and the drive portion 204 are always accommodated in the housing cavity. The guide portion 202 is configured to guide the drive shaft 108 to move along the first direction X and rotate about the first direction X relative to the housing 102. The drive portion 204 is configured to cooperate with a transmission member 212 so that a drive member 214 can drive the drive shaft 108 to move. In the present application, the drive member 214 is a motor and the guide portion 202 is a guide external thread.

[0045] As Figure 2 shown, the actuating assembly is arranged in the housing cavity of the housing 102. The actuating assembly includes the drive member 214 and the transmission member 212. The drive member 214 has an output portion 216. The output portion 216 is rotatable about an axis extending along the first direction X. The transmission member 212 includes a first transmission portion 222 and a second transmission portion 224. The first transmission portion 222 and the second transmission portion 224 are connected. The first transmission portion 222 is engaged with the output portion 216 so that the rotation of the first transmission portion 222 drives the transmission member 212 to rotate. The second transmission portion 224 is engaged with the drive portion 204 so that the rotation of the second transmission portion 224 drives the drive shaft 108 to rotate. In the present application, the output portion 216 is a first drive worm. The first transmission portion 222 is a first drive external thread. The second transmission portion 224 is a second drive worm. The drive portion 204 is a second drive external thread.

[0046] As Figure 2As shown, the mounting openings of the housing cavity of housing 102 are generally located in the same plane (i.e., a plane generally perpendicular to the second direction Y). The cover plate 104 can be connected to housing 102 by welding (e.g., plastic welding).

[0047] like Figure 2 As shown, the sealing assembly 106 includes a first sealing housing 232, a second sealing housing 234, and a seal 236. The first sealing housing 232 is disposed in the output opening and connected to the housing 102. The second sealing housing 234 is connected to the first sealing housing 232 and forms a sealing cavity. The seal 236 is disposed in the sealing cavity. Through holes are provided in the first sealing housing 232, the second sealing housing 234, and the seal 236, allowing the sealing portion 206 of the drive shaft 108 to extend out of the first sealing housing 232, the second sealing housing 234, and the seal 236. When the actuation assembly is assembled in place, the seal 236 is disposed between the drive shaft 108 and the first sealing housing 232, thereby forming a seal.

[0048] like Figure 2 As shown, the sealing assembly 106 is connected to the housing 102 via a first sealing housing 232. Specifically, the sealing assembly 106 is movable along a first direction X, thereby being mounted onto the housing 102. Specifically, the first sealing housing 232 is provided with a first guide structure. The housing 102 is provided with a second guide structure. The first guide structure and the second guide structure can cooperate with each other to guide the sealing assembly 106 to move relative to the housing 102 along the first direction X. In this application, the first guide structure includes two guide protrusions 242 provided on the first sealing housing 232. The guide protrusions 242 extend radially (e.g., perpendicular to the first direction X) from the first sealing housing 232. The second guide structure includes two guide recesses 244 provided on the housing 102. The guide recesses 244 are located at the output opening and are recessed inward from the inner wall of the housing cavity. The guide protrusions 242 are movable along the first direction X, thereby entering the guide recesses 244. When the first sealing housing 232 is assembled with the housing 102, the first sealing housing 232 can be connected to the housing 102 by welding (e.g., plastic welding).

[0049] It should be noted that although the first guide structure in this application includes two guide protrusions 242 and the second guide structure includes two guide recesses 244, at least one guide protrusion and at least one guide recess are both within the protection scope of this application.

[0050] It should also be noted that although the first guiding structure in this application includes a guiding protrusion 242 and the second guiding structure includes a guiding recess 244, any mutually cooperating first and second guiding structures formed by these structures are within the protection scope of this application.

[0051] As shown in Figure 2 , the first sealing housing 232 and the second sealing housing 234 are connected together. Specifically, the first sealing housing 232 is provided with a first connecting structure. The second sealing housing 234 is provided with a second connecting structure. The first connecting structure can cooperate with the second connecting structure, so that the first sealing housing 232 and the second sealing housing 234 are connected together. The first connecting structure includes four connecting recesses (not shown) provided on the first sealing housing 232. The four connecting recesses are uniformly arranged along the circumference of the first sealing housing 232. The second connecting structure includes four connecting protrusions 252 provided on the second sealing housing 234. The four connecting protrusions 252 are uniformly arranged along the circumference of the second sealing housing 234. The connecting protrusions 252 can enter the connecting recesses. In this application, the size of the connecting protrusions 252 is slightly larger than the size of the connecting recesses, so that the first sealing housing 232 is connected with the second sealing housing 234 by interference fit.

[0052] It should be noted that although the first connecting structure in this application includes four connecting recesses and the second connecting structure includes four connecting protrusions 252, at least one connecting protrusion and at least one connecting recess are within the protection scope of this application.

[0053] It should also be noted that although the first connecting structure in this application includes connecting recesses and the second connecting structure includes connecting protrusions 252, any structure of the first connecting structure and the second connecting structure formed by mutual cooperation are within the protection scope of this application.

[0054] As shown in Figure 2 , the second sealing housing 234 is generally annular. The second sealing housing 234 includes a second main body 262 and a second abutting portion 264 connected together. The outer diameter of the second main body 262 is greater than the outer diameter of the second abutting portion 264. The connecting protrusions 252 are formed by extending radially outward from the outer circumferential surface of the second abutting portion 264.

[0055] As shown in Figure 2 , the first sealing housing 232 is generally annular. The first sealing housing 232 includes a first main body 266 and a first abutting portion 268 connected together. The outer diameter of the first main body 266 is greater than the outer diameter of the first abutting portion 268. The inner diameter of the first abutting portion 268 is equal to or slightly smaller than the outer diameter of the second abutting portion 264, so that at least a part of the second abutting portion 264 can be located on the inner side of the first abutting portion 268. When the sealing assembly 106 is assembled in place, the outer side surface of the second abutting portion 264 and the outer side surface of the first abutting portion 268 are apart by a distance, thereby forming a sealing cavity to accommodate the sealing member 236.

[0056] As shown in Figure 3As shown, the seal 236 is annular. When the sealing assembly 106 is assembled in place, one side of the seal 236 can abut against the first sealing housing 232, and the other side of the seal 236 can abut against the second sealing housing 234. In this application, the seal 236 has an X-shaped cross-section. It should be noted that in other embodiments, the cross-section of the seal 236 may also be other shapes.

[0057] Figure 1 Is it like this? Figure 3 The diagram shows a cross-sectional view of the actuation component of this application. Figure 3 As shown, the housing cavity of housing 102 has a first cavity wall 302, a second cavity wall 304, and a third cavity wall 306. The first cavity wall 302 and the third cavity wall 306 are annular around a first direction X. The second cavity wall 304 is located between the first cavity wall 302 and the third cavity wall 306, and is substantially perpendicular to the first cavity wall 302 and the third cavity wall 306. In other words, the second cavity wall 304 is substantially perpendicular to the first direction X. The diameter of the first cavity wall 302 is larger than the diameter of the third cavity wall 306, thereby forming a stepped portion among the first cavity wall 302, the second cavity wall 304, and the third cavity wall 306. When the actuation assembly is assembled in place, the first abutment portion 268 of the first sealing housing 232 abuts against the first cavity wall 302, and the second body 262 of the second sealing housing 234 also abuts against the first cavity wall 302. In the first direction X, there is a certain distance between the wall surface of the second body 262 of the second sealing housing 234 away from the first sealing housing 232 and the second cavity wall 304, so that when the actuation assembly is started, the lubricating oil in the actuation assembly can be partially deposited at the step portion.

[0058] Therefore, the first cavity wall 302 defines the output opening. In other words, the output opening is defined by a one-piece structure, so that there are no gaps on the wall surface surrounding the output opening.

[0059] like Figure 3 As shown, the seal 236 has two opposing sealing surfaces. When the actuation assembly is assembled in place, one sealing surface of the seal 236 abuts against the drive shaft 108, and the other sealing surface abuts against the first abutment portion 268 of the first sealing housing 232, thereby preventing liquid from entering the housing along the outer surface of the drive shaft 108.

[0060] like Figure 3 As shown, the inner wall of the housing cavity of the housing 102 is also provided with a housing guide thread 312, which is used to engage with the drive guide thread on the drive shaft 108, thereby guiding the drive shaft 108 to move relative to the housing 102 in the first direction X. The housing guide thread 312 is integrally formed with the housing 102.

[0061] like ​As shown, the first sealing housing 232 is further provided with a groove 322. Specifically, the groove 322 is arranged on the first body 266 and surrounds the first direction X. When the actuating assembly is assembled in place, a portion of the housing 102 is accommodated in the groove 322. The operator connects the first sealing housing 232 and the housing 102 by welding. When welding, the housing 102 located in the groove 322 can be melted in the groove 322.

[0062] In the prior art, the sealing level of the actuating assembly is low and the service life is short. The inventor of the present application found that this is because the housing in the prior art is connected by a substantially symmetrical upper half housing and a lower half housing. Specifically, the connecting seam of the upper half housing and the lower half housing is substantially located in the same plane, the sealing element is arranged between the upper half housing and the lower half housing, and the sealing element is arranged perpendicular to the plane. Since the drive shaft translates and rotates relative to the sealing element, the drive shaft exerts a large force on the sealing element, which can cause the sealing element to deform outwardly as a whole, causing the connecting seam to crack and leading to failure of the sealing element.

[0063] The actuating assembly of the present application has good sealing performance and a long service life. Specifically, the first sealing housing and the housing are connected, and the first sealing housing and the second sealing housing form a sealed cavity to accommodate the sealing element. Thus, the sealing element of the present application can be kept in place, and the deformed sealing element under the movement of the drive shaft does not directly act on both the connected first sealing housing and the housing, but only acts on the first sealing housing, thereby ensuring good connection and sealing of the first sealing housing and the housing.

[0064] Although the present disclosure has been described in connection with the examples of the embodiments outlined above, various alternatives, modifications, variations, improvements, and / or substantial equivalents, whether known or not, can become apparent to those of ordinary skill in the art.
