Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile parts, in particular to an automobile electrically-operated flap actuator with ice-breaking function. BACKGROUND

[0002] The automobile flap (such as the charging flap and the refueling flap) is an important functional part of the vehicle body, which not only provides shielding protection, but also undertakes multiple responsibilities such as sealing and dustproofing, waterproofing and anti-freezing, safety locking, and user interaction. The reliability of the electrically-operated flap actuator as an important functional part of the vehicle body directly affects the user experience. In cold weather conditions, the charging flap and the refueling flap are prone to icing, which causes the traditional actuator to fail to open normally.

[0003] A charging port box assembly structure of an electric vehicle is disclosed in Chinese patent CN106627791B, which comprises a charging port box arranged in a charging port of a side panel of a vehicle body. The bottom of the charging port box is provided with a charging seat connected to the inside of the vehicle body. The opening end of the charging port box is provided with a charging port cover. One end of the charging port cover is rotatably connected to one side of the charging port box. A torsional spring is arranged at the rotatable connection. The other side of the charging port box is provided with a press-type buckle. The inner side of the charging port cover is provided with a connecting head connected to the press-type buckle. The edge of the charging port of the side panel of the vehicle body is inwardly bent to form an annular flange. The opening end of the charging port box extends outwardly to form a retaining ring. The upper side of the retaining ring is provided with an annular sealing ring. The annular sealing ring and the retaining ring are detachably connected.

[0004] The electrically-operated actuator in the prior art adopts a linear press-type structure, which can only provide axial thrust in icing conditions and is difficult to effectively break the ice layer. There is still a risk of opening failure when icing. In addition, the electrically-operated actuator in the prior art lacks an emergency opening mechanism and relies mainly on a single electric drive mode. When the circuit fails, the battery is discharged, or the mechanism is stuck, there is a lack of reliable mechanical emergency opening scheme. In particular, in emergency situations such as accident rescue, the inability to open the flap will seriously affect the rescue efficiency. In addition, in order to meet the ice-breaking torque requirement, the actuator needs to increase the number of transmission stages, but the installation space on the vehicle is strictly limited. Although the charging port box assembly is provided with a sealing structure, it does not solve the contradiction between large torque transmission and compact layout, resulting in an excessively large product size. In particular, the profile of the actuator housing increases the installation limitations of the actuator in the vehicle body. SUMMARY

DETAILED DESCRIPTION

[0045] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0046] It should be understood that although the terms upper, middle, lower, top end, one end, etc. appear herein to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for the purpose of understanding, and are not used to define any directional or sequential limitation.

[0047] As shown in Figures 1-5 An automobile electric flap actuator with ice breaking function comprises:

[0048] A shell assembly 1 with a cavity, a push rod 2 arranged in the shell assembly 1, and a driving assembly 3 and an electrical assembly 4 for actuating the push rod 2 to perform a telescopic action;

[0049] The driving assembly 3 comprises a motor 31 for providing actuating force, a main drive module 32 arranged in the cavity, a manual drive module 33 arranged outside the cavity, and an intermediate gear 34 associated with the main drive module 32 and the manual drive module 33;

[0050] The main drive module 32 is arranged to be electrically started and to provide a large torque driving force for the push rod 2 to achieve an ice breaking effect. The main drive module 32 at least comprises a stud 321 associated with the motor 31 through the intermediate gear 34, i.e. the intermediate gear 34 is in driving connection with the motor 31. The push rod 2 is provided with an internal thread 23 matched with the stud 321. The motor 31 provides driving force for the stud 321 through the intermediate gear 34. The push rod 2 drives the flap to perform a telescopic action in response to the rotation of the stud 321;

[0051] The manual drive module 33 is arranged to be started in an emergency in case of power failure. The manual drive module 33 comprises a drive seat 331 arranged outside the shell assembly 1, and an unlocking traction member 332 arranged on the drive seat 331. The intermediate gear 34 extends to the outside of the shell assembly 1 and is in driving connection with the drive seat 331. The drive seat 331 is arranged at the back of the shell assembly 1 corresponding to the main drive module 32. The unlocking traction member 332 extends to the vehicle body for manual operation by a user and can be actuated manually to drive the drive seat 331 to rotate the intermediate gear 34, and further drive the stud 321 to rotate, so that the drive seat 331 drives the flap to perform an extension action in response to the rotation of the unlocking traction member 332;

[0052] The electrical assembly 4 comprises:

[0053] The first electrical component 41 is arranged parallel to the axis of the motor 31, and the second electrical component 42 is arranged at the end of the first electrical component 41, and the second electrical component 42 is perpendicular to the axis of the motor 31. The driving transmission module 32 is arranged in the profile enclosed by the electrical assembly 4 and the axis of the motor 31, and the manual transmission module 33 is arranged at the back of the driving transmission module 32. The end of the first electrical component 41 is extended with an electrical connection end 43. Preferably, the electrical connection end 43 is arranged linearly along the first electrical component 41, or the electrical connection end 43 is arranged side by side on one side of the motor 31, and the second electrical component 42 is connected between the first electrical component 41 and the electrical connection end 43.

[0054] The electrical assembly 4 and the motor 31 in the embodiment form a transmission area in the cavity of the housing assembly 1, realizing a compact spatial layout. The driving transmission module 32 and the manual transmission module 33 are arranged on opposite sides of the transmission area based on the spatial occupation of the push rod 2 and the stud 321 on the telescopic axis. The electrical assembly 4 further includes a circuit board 421 as part of the first electrical component 41 or the second electrical component 42, which is arranged in the height direction of the telescopic axis, thereby forming a three-dimensional enclosed layout. In addition, the electrical connection end 43 is arranged within the regular profile of the housing assembly 1, specifically extending from the end of the first electrical component 41 parallel to the axis of the motor 31, reducing the extension of the electrical connection end 43 outside the rectangular area defined by the housing assembly 1, thereby reducing the overall structure volume, and ensuring the driving of large torque and manual emergency unlocking in a limited space, as well as the reliable installation of the electrical assembly 4.

[0055] As shown in Figures 2 to 8 As a further embodiment of the driving transmission module 32, the driving transmission module 32 includes a double gear 322 and a worm 323 arranged on the output end of the motor 31. The upper end of the double gear 322 is a helical gear, the upper end of the double gear 322 is meshed with the worm 323, the lower end of the double gear 322 is meshed with the intermediate gear 34, and the intermediate gear 34 is coaxially arranged with the stud 321 and rotates synchronously with the stud 321. In this embodiment, the worm 323 and the helical gear cooperate to provide large torque and stable thrust output, thereby breaking the ice on the car's hood.

[0056] As a further explanation of the intermediate gear 34, the intermediate gear 34 is preferably fixedly arranged with the stud 321 and rotates synchronously with the stud 321, and has coaxial first gear 341 and second gear 342, the first gear 341 is used to mesh with the lower end of the double gear 322, and the first gear 341 is preferably fixed or integrally arranged at the lower end of the stud 321; the second gear 342 extends out of the housing assembly 1 and is fixedly connected with the stud 321 or integrally extends at the lower end of the stud 321. Through the above improvement, the intermediate gear 34 is integrated at the bottom of the stud 321, thereby further optimizing the space utilization in the cavity, and the intermediate gear 34 is associated with the driving transmission module 32 and the manual transmission module 33, and only needs to operate the unlocking traction 332 outside the housing assembly 1 to drive the intermediate gear 34 and the stud 321 to rotate through the transmission seat 331.

[0057] As shown in Figure 2 and Figures 9 to 10 As a further embodiment of the manual transmission module 33, the transmission seat 331 is arranged at the bottom of the housing assembly 1, and the transmission seat 331 is a circular seat body opening toward the bottom of the housing assembly 1, the inner wall of the transmission seat 331 is provided with an inner gear ring 333, the second gear 342 of the intermediate gear 34 is arranged in the housing assembly 1 and meshes with the inner gear ring 333, the inner gear ring 333 is an incomplete gear ring, and the transmission seat 331 also has a avoiding portion 338 in the circumferential direction which is connected with the gear ring, and the arrangement of the gear ring in the inner wall of the transmission seat 331 only needs to complete the extension stroke of the push rod 2, in this embodiment, by selecting the gear ring as the emergency unlocking transmission member, the height space occupation of the manual transmission module 33 outside the housing assembly 1 can be effectively controlled.

[0058] As preferred, in the normal state, the second gear 342 of the intermediate gear 34 is spaced from the inner gear ring 333 and does not form meshing transmission with the inner gear ring 333, so as not to affect the position of the manual transmission module 33 when the driving transmission module 32 is actuated.

[0059] Specifically, the rotation axis of the manual transmission module 33 is arranged in parallel with the extension axis of the push rod 2, which aims to limit the spatial arrangement of the manual transmission module 33 within the profile of the housing assembly 1, thereby reducing the planar space occupation of the manual transmission module 33. Further, the transmission seat 331 is coaxially arranged with the double gear 322, and the housing assembly 1 has an outwardly extending fixed shaft 337 at a position corresponding to the shaft portion of the double gear 322, which is used to provide a mounting position for the transmission seat 331. The fixed shaft 337 is threaded through the transmission seat 331 and fixed in axial position by the torsion spring 334. Inside the cavity of the housing assembly 1, the upper end of the double gear 322 is engaged with the intermediate gear 34, and the intermediate gear 34 is engaged with the transmission seat 331. By arranging the fixed shaft 337 at the bottom of the double gear 322, the compactness of the manual transmission module 33 and the driving transmission module 32 in the housing assembly 1 is further improved while ensuring the transmission ratio of the driving transmission module 32.

[0060] Further referring to Figure 9 As shown, in order to achieve automatic resetting after emergency unlocking, the manual transmission module 33 further includes a fixed torsion spring 334 sleeved on the rotation axis of the transmission seat 331. The torsion spring 334 is preferably sleeved on the fixed shaft 337 described above. The bottom of the housing assembly 1 is provided with a first limiting block 335 accommodated in the transmission seat 331, and a second limiting block 336 fixed in the transmission seat 331. The two ends of the torsion spring 334 are respectively abutted on the first limiting block 335 and the second limiting block 336. The torsion spring 334 provides a resetting driving force for the transmission seat 331. At the same time, the first limiting block 335 and the second limiting block 336 provide a stop limit for the two ends of the torsion spring 334, so that the transmission seat 331 presses the torsion spring 334 after rotation, thereby storing energy for the torsion spring 334. After completing the emergency unlocking, the torsion spring 334 actuates the second limiting block 336 and drives the transmission seat 331 to the initial position, which refers to the position where the intermediate gear 34 is separated from the inner ring gear 333.

[0061] Among them, the unlocking traction member 332 is a traction rope, and the unlocking traction member 332 is arranged on the circumferential side of the rotation axis of the transmission seat 331. When the unlocking traction member 332 is pulled, the transmission seat 331 is driven to rotate, thereby performing emergency unlocking. At this time, the transmission seat 331 drives the stud 321 to rotate through the intermediate gear 34.

[0062] As Figures 6 to 8As shown, as a further improvement of the push rod 2, a helical groove 21 is provided on the outer wall of the push rod 2, a rotating guide column 51 is provided on one side of the outer wall of the push rod 2, the rotating guide column 51 extends in the axial direction of the push rod 2, and the rotating guide column 51 has a guide column 511 extending radially into the helical groove 21, the end of the helical groove 21 is open for the guide column 511 on the rotating guide column 51 to be inserted, and the guide column 511 is fixedly arranged. During the axial extension and retraction action of the push rod 2, the push rod 2 is guided by the guide column 511 of the helical groove 21, forcing the push rod 2 to rotate around its axis to perform a rotational extension and retraction action, thereby further improving the ice breaking force and being more conducive to the opening of the car hood. On the other hand, the guide column 511 inserted into the helical groove 21 also improves the reliability of the action of the push rod 2 to a certain extent.

[0063] Further referring to Figure 3 As shown, a limiting convex edge 22 is provided on the side edge of the push rod 2, and a limit switch 6 is provided at the retracted position of the push rod 2. In the retracted position, the limit switch 6 abuts against the limiting convex edge 22, thereby ensuring the position of the push rod 2. In addition, the rotating guide column 51 is arranged on one side of the limiting convex edge 22 and the push rod 2 and extends in the vertical direction. When the push rod 2 reaches the limit of the extended position, the limiting convex edge 22 is arranged opposite to the side edge of the rotating guide column 51 in the rotating direction, and when the push rod 2 reaches the limit of the retracted position, the limiting convex edge 22 abuts against the side edge of the rotating guide column 51, thereby providing reliable limiting for the limit position of the push rod 2. When the push rod 2 starts the extension action, the limiting convex edge 22 gradually moves away from the limit switch 6, thereby ensuring that the push rod 2 performs the extension action under the control command.

[0064] In the present embodiment, in order to further optimize the space in the shell assembly 1, the shell assembly 1 comprises an upper shell 14 and a lower shell 15 which are spliced with each other, and a limiting framework 5 which is limited between the upper shell 14 and the lower shell 15. The limiting framework 5 extends on both sides of the push rod 2 and the stud 321, and the profile of the limiting framework 5 matches the profile of the shell assembly 1. The end of the output end of the motor 31 is abutted on one side of the limiting framework 5, the rotating guide column 51 is integrally formed on the limiting framework 5, and the rotating guide column 51 extends on the limiting framework 5. The first electrical component 41 is constrained between the limiting structure in the limiting framework 5 and the upper shell 14, thereby ensuring the position reliability of the first electrical component 41.

[0065] As shown in Figure 7 , Figure 13 and Figure 14 As a further embodiment of the limiting framework 5, the axis extension direction of the output end of the motor 31 is defined as the first direction, and the direction perpendicular to the first direction is defined as the second direction, or in other words, the length direction of the shell assembly 1 is the first direction, and the width direction of the shell assembly 1 is the second direction.

[0066] The limiting framework 5 is specifically located in the space parallel to the first direction of the motor 31 axis and the first electrical component 41, and is connected in the width direction between the motor 31 axis and the first electrical component 41. The limiting framework 5 is provided with a first gap 52 and a second gap 53 arranged parallel to the first electrical component 41. The stud 321 is arranged in the first gap 52. The push rod 2 is arranged above the limiting framework 5. The limit switch 6 is arranged in the second gap 53. The first gap 52 and the second gap 53 are arranged opposite in the first direction. The electrical connection end 43 and the motor 31 are arranged on one side of the limiting framework 5 close to the first gap 52. The second electrical component 42 at least includes a circuit board 421. The circuit board 421 is arranged on one side of the limiting framework 5 close to the second gap 53 and is arranged along the second direction and connected between the first electrical component 41 and the motor 31 axis. Preferably, the circuit board 421 is specifically arranged at the end of the shell assembly 1 in the first direction and is constrained between the limiting framework 5 and the gap of the shell assembly 1 in the first direction.

[0067] Through the above improvement, the limiting framework 5 divides each module and electrical component in the cavity of the shell assembly 1, realizes reasonable planning of the cavity space in the first direction, the second direction and the vertical direction, and provides installation and limiting positions for the electrical component, the driving transmission module 32 and the limit switch 6, effectively improving the convenience of assembly.

[0068] Referring to FIGS. 1-3, Figure 4 , Figure 14 As a further embodiment of the electrical assembly 4, for the second electrical component 42, the second electrical component 42 specifically refers to the circuit board 421 and the second electrical connector 422 arranged at both ends of the driving transmission module 32 in the first direction. The circuit board 421 and the second electrical connector 422 are arranged parallel along the second direction;

[0069] For the first electrical component 41, the first electrical component 41 specifically refers to the first electrical connector 411 connected between the circuit board 421 and the electrical connection end 43 along the first direction and arranged parallel and adjacent to the motor 31 axis. The driving transmission module 32 is arranged between the first electrical component 41 and the motor 31 axis;

[0070] The second electrical connector 422 is connected between the electrical connection end 43 and the motor 31. The electrical connection end 43 has a connecting surface arranged inside the shell assembly 1. The second electrical connector 422 and the first electrical connector 411 are both connected to the connecting surface. The second electrical connector 422 is connected from the connecting surface of the electrical connection end 43 to the side of the motor 31;

[0071] Furthermore, the first electrical connector 411 and the second electrical connector 422 are composed of a plurality of electrode plates, which are arranged vertically. The circuit board 421 extends vertically and connects to the start switch 7 and the stop switch 6, thereby making full use of the vertical space within the housing assembly 1. The first electrical connector 411, the second electrical connector 422, the circuit board 421, the output end of the motor 31, and the limiting frame 5 enclose each other to form a transmission area. The active transmission module 32 is arranged within the transmission area. With the second electrical connector 422 as the boundary, the tail of the motor 31 and the electrical connection end 43 extend parallel to each other outside the transmission area. In this way, a compact spatial layout is formed inside the housing assembly 1, and the electrical connection end 43 is arranged within the regular outline of the housing assembly 1. Specifically, it extends parallel to the axis of the motor 31 from the end of the first electrical component 41, reducing the extension of the electrical connection end 43 outside the rectangular area defined by the housing assembly 1, thereby reducing the overall structural volume.

[0072] Reference Figure 13 As shown, in order to further constrain the positional stability of the electrical components and the limiting frame 5 inside the housing assembly 1, the housing assembly 1 is provided with a limiting channel 16 that matches the transmission area. The limiting channel 16 includes a first channel 161, a second channel 162, a third channel 163, a fourth channel 164 and a fifth channel 165.

[0073] The first channel 161 is arranged along the side boundary of the housing assembly 1 in the first direction, and the first electrical component 41 is limited in the first channel 161; the second channel 162 is arranged on one side of the electrical connection end 43 and the output end of the motor 31 in the second direction, and the second electrical connector 422 is limited in the second channel 162; the third channel 163 is arranged on the side away from the active drive module 32 and the motor 31 in the second direction, and close to the end boundary of the housing assembly 1, and the circuit board 421 is inserted and limited in the third channel 163; the fourth channel 164 is arranged parallel to the third channel 163, and the limiting frame 5 is provided with a concave and convex part 54 that is inserted into the third channel 163; the fifth channel 165 is used for inserting the motor 31, and the output end of the motor 31 is arranged on the limiting frame 5.

[0074] In other embodiments, both the first electrical connector 411 and the second electrical connector 422 are provided with electrode frames 412 to ensure the positional stability of the first electrical connector 411 and the second electrical connector 422 within the housing assembly 1.

[0075] like Figure 14 As shown, the first electrical component 41 is further provided with a bent portion 413 at the end away from the electrical connection end 43, the first channel 161 is bent in correspondence with the bent portion 413, and the rotating guide post 51 is provided with a limiting edge that matches the bent portion 413, thereby using the limiting frame 5 to further limit the first electrical component 41.

[0076] from Figure 4 As can be seen from this, in some other embodiments, the first electrical component 41 and / or the second electrical component 42 are arranged to extend along the telescopic direction of the push rod 2 in order to make full use of the vertical space inside the housing assembly 1 and reduce the occupancy in the planar profile direction.

[0077] like Figure 1 and Figure 2 ,as well as Figure 15 As shown, the housing assembly 1 is provided with a start switch 7 adjacent to the push rod 2. The start switch 7 is exposed outside the housing assembly 1 and connected to the circuit board 421. It is worth mentioning that the electrical components on the circuit board 421 are all located on the side away from the active transmission module 32, so as to avoid the interference of the mechanical components on the electrical components. In order to ensure the sealing and waterproof performance of the housing assembly 1, the start switch 7 is covered with a sealing member 8. The sealing member 8 extends toward the push rod 2 and surrounds the outer wall of the push rod 2 to ensure the sealing of the moving components on the housing assembly 1.

[0078] Specifically, the control end of the start switch 7 extends outside the housing assembly 1, while the control part of the start switch 7 is placed inside the cavity and fixed to the circuit board 421 on the side away from the active drive module 32. This allows the start switch 7 to be driven by pressing the sealing member 8, and ensures the sealing protection of the start switch 7. At the same time, the sealing member 8 has an annular abutment part that abuts against the outer periphery of the push rod 2, ensuring the sealing between the push rod 2 and the housing assembly 1.

[0079] Alternatively, the upper housing 14 and the lower housing 15 of the housing assembly 1 may be ultrasonically welded together.

[0080] It should be noted that the start switch 7 refers to the control of the motor 31 and the active drive module 32. It can be used to trigger the extension and retraction of the push rod 2, or it can be used only to trigger the extension of the push rod 2.

[0081] Further reference Figure 15 As shown, as a further embodiment of the sealing member 8, the housing assembly 1 is provided with a first opening 12 for the push rod 2 to extend out, a second opening 13 for the start switch 7 to extend out, and a connecting rib 11 connecting the first opening 12 and the second opening 13. A first seat 17 and a second seat 18 are provided on both sides of the connecting rib 11. The first seat 17 and the second seat 18 are spaced apart in a first direction. The first seat 17 is used for the push rod 2 to be inserted, and the first opening 12 is located on the top of the first seat 17. The second seat 18 is used for the circuit board 421 to be arranged, and the second opening 13 is located on the top of the second seat 18.

[0082] like Figure 11 andFigure 12 As shown, the sealing member 8 includes a first sealing portion 81 sleeved on the first opening 12, a second sealing portion 82 embedded on the second opening 13, and a connecting portion 83 connected between the first sealing portion 81 and the second sealing portion 82, and the connecting portion 83 is embedded on the connecting rib 11 and the shell assembly 1. Through the above improvement, the first sealing portion 81 and the second sealing portion 82 are connected by the connecting portion 83, so that the sealing member 8 forms an integrated structure, and the convenience of installation of the sealing member 8 is improved.

[0083] Specifically, the connecting portion 83 includes a first connecting edge 831 extending in the first direction, a second connecting edge 832 extending in the second direction, and a third connecting edge 833 extending in the vertical direction, wherein the third connecting edge 833 is connected to the first sealing portion 81, the first connecting edge 831 and the second connecting edge 832 are connected to the second sealing portion 82, the first connecting edge 831 and the third connecting edge 833 are connected, and the sealing member 8 is embedded on the end face of the shell assembly 1, thereby improving the convenience of installation of the integrated sealing member 8.

[0084] As a further embodiment of the cooperation between the sealing member 8 and the shell assembly 1, the shell assembly 1 is provided with a limiting embedding groove 19 for embedding the sealing member 8, wherein the limiting embedding groove 19 includes a first embedding groove 191 provided on the connecting rib 11, a second embedding groove 192 provided on the end face of the second seat body 18, a third embedding groove 193 provided on the circumferential side wall of the first seat body 17, a first ring groove 194 provided on the circumferential side of the first opening 12, and a second ring groove 195 provided on the circumferential side of the second opening 13. The sealing member 8 is respectively embedded in the corresponding limiting embedding groove 19, and the above-mentioned limiting embedding grooves 19 are all communicated with each other, wherein the first sealing portion 81 is tightly held on the push rod 2, and the second sealing portion 82 extends into the cavity through the second ring groove 195, so that the sealing member 8 is embedded in the shell assembly 1 in the horizontal direction and the vertical direction, thereby effectively improving the stability of the installation of the sealing member 8.

[0085] In other embodiments, the end of the first connecting edge 831 or the second connecting edge 832 or the third connecting edge 833 is also provided with a reinforcing portion 84, and the thickness of the reinforcing portion 84 is greater than the thickness of the adjacent connecting edge, so as to improve the reliability of the embedding position of the part. As an example, the reinforcing portion 84 is provided at the end of the second connecting edge 832.

[0086] The specific embodiment is only an explanation of the application, and is not a limitation of the application. Those skilled in the art can make modifications to the embodiment without creative contribution after reading the specification, but as long as the modifications are within the scope of the claims of the application, they are protected by the patent law.
