Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and more specifically, to a clutch mechanism and a vehicle. Background Technology

[0002] With the development of intelligent vehicles, more and more new energy vehicles are changing their charging port covers from manual to electric opening, making the whole vehicle more technological and stylish.

[0003] Currently, electric charging port covers are opened and closed by an actuator that electrically drives the cover. However, due to the limitation of the actuator torque, the closing force of the charging port cover is insufficient, and it may be thrown off under conditions such as high-speed driving or sharp turns. To solve this problem, a clutch structure is usually added inside the actuator to increase the holding force of the charging port cover when it is closed by utilizing the clutch force generated when the clutch structure is engaged.

[0004] However, conventional clutches typically use a trapezoidal tooth crown tooth structure to achieve engagement. When users habitually close the electric charging port cover manually, they need to apply a large torque to close the cover, which is extremely inconvenient and affects the user experience. Utility Model Content

[0005] The problem this invention addresses is: how to improve the convenience of manually closing the electric charging port cover.

[0006] To solve the above problems, this utility model provides a clutch mechanism and a vehicle.

[0007] In a first aspect, this utility model provides a clutch mechanism, including a first engaging member, a second engaging member, and a clutch shaft; the first engaging member is used for transmission connection with the rotating shaft of a flip cover, the second engaging member is used for transmission connection with a drive motor through the clutch shaft, and the second engaging member and the clutch shaft are slidably connected in the axial direction of the clutch shaft; the first engaging member and the second engaging member are respectively provided with end face tooth structures, the first engaging member and the second engaging member are used for engagement through the end face tooth structures, the end face tooth structures include a first tooth surface and a second tooth surface, and the inclination angle of the first tooth surface is smaller than the inclination angle of the second tooth surface;

[0008] Wherein, the first tooth surface is the tooth surface that contacts the first meshing member and the second meshing member when they rotate toward the direction of closing the flip cover, the second tooth surface is the tooth surface that contacts the first meshing member and the second meshing member when they rotate toward the direction of opening the flip cover, the inclination angle of the first tooth surface is the acute angle formed by the first tooth surface and the plane perpendicular to the axis of the clutch shaft, and the inclination angle of the second tooth surface is the acute angle formed by the second tooth surface and the plane perpendicular to the axis of the clutch shaft.

[0009] Optionally, the first tooth surface and the adjacent second tooth surface are smoothly connected by a circular arc surface.

[0010] Optionally, the clutch mechanism further includes a clutch housing, which covers the second engagement member and is connected to the clutch shaft. One end of the first engagement member is provided with the end face tooth structure, and the other end passes through the clutch housing and is connected to the rotating shaft for transmission.

[0011] Optionally, the first meshing member includes a meshing portion having the end face tooth structure and a connecting shaft portion for transmission connection with the rotating shaft. The connecting shaft portion is disposed at one end of the meshing portion away from the second meshing member and coincides with the central axis of the meshing portion. The end face of the meshing portion away from the second meshing member abuts against the clutch housing.

[0012] Optionally, one end of the clutch housing is provided with a pawl, and the clutch shaft is provided with a slot, and the clutch housing and the clutch shaft are engaged by the pawl and the slot.

[0013] Optionally, the clutch mechanism further includes an elastic element disposed on the side of the second engaging member away from the first engaging member, for providing an elastic force to the second engaging member.

[0014] Optionally, the clutch shaft is provided with a shoulder structure, and the end of the elastic element away from the second engaging element abuts against the shoulder structure.

[0015] Optionally, the elastic element is a wave spring sleeved outside the clutch shaft.

[0016] Optionally, the second engaging member is splinedly connected to the clutch shaft.

[0017] Secondly, this utility model provides a vehicle including the clutch mechanism described above.

[0018] The beneficial effects of the clutch mechanism and vehicle of this utility model are as follows: By setting end-face tooth structures on the first and second meshing parts respectively, the first and second meshing parts can be engaged through the end-face tooth structures. Simultaneously, by drivingly connecting the first meshing part to the rotating shaft of the flip cover, and drivingly connecting the second meshing part to the drive motor through the clutch shaft, the drive motor can transmit its rotational motion to the rotating shaft of the flip cover via the clutch mechanism, thereby achieving automatic opening or closing of the flip cover. Furthermore, by designing the inclination angle of the first tooth surface of the end-face tooth structure to be smaller than the inclination angle of the second tooth surface, the inclination angle of the contact surface of the end-face tooth structure in the closing direction of the flip cover is smaller than the inclination angle of the contact surface in the opening direction of the flip cover. This means that when the user manually closes the flip cover, the torque applied to the flip cover is smaller than the torque required to open it, reducing the resistance when the user manually closes the flip cover, thus improving the convenience of manually closing the flip cover and enhancing the user experience.

[0030] In related technologies, a clutch mainly includes an upper clutch tooth, a lower clutch tooth, a wave spring, and a clutch input shaft. The upper clutch tooth is connected to the rotating shaft of the charging port cover, and the lower clutch tooth is connected to the clutch input shaft via a keyway. The upper and lower clutch teeth typically use a crown tooth structure, such as isosceles trapezoidal teeth, to achieve meshing. When a user habitually closes the electric charging port cover manually after the vehicle is fully charged, the lower clutch tooth does not rotate, causing the charging port cover to drive the upper clutch tooth to rotate relative to the lower clutch tooth. During this process, when the trapezoidal tooth of the upper clutch tooth falls from the tip of the trapezoidal tooth of the lower clutch tooth to the root, a "clunking" sound is produced, resulting in abnormal noise. Moreover, because the inclination angles of the two helical tooth surfaces of the trapezoidal tooth are the same, the user needs to apply a large torque to move the trapezoidal tooth of the upper clutch tooth from the tooth surface of the trapezoidal tooth of the lower clutch tooth to the tooth tip, and then let it fall from the tooth tip to the root of the lower clutch tooth, affecting the user experience.

[0031] In view of the problems existing in the above-mentioned related technologies, this utility model provides a clutch mechanism and a vehicle.

[0032] Combination Figure 1 , Figure 2 and Figure 5 As shown, the present invention provides a clutch mechanism 100, including a first engaging member 1, a second engaging member 2, and a clutch shaft 3; the first engaging member 1 is used for transmission connection with the rotating shaft 210 of the flip cover 200, the second engaging member 2 is used for transmission connection with the drive motor 300 through the clutch shaft 3, and the second engaging member 2 and the clutch shaft 3 are slidably connected in the axial direction of the clutch shaft 3; the first engaging member 1 and the second engaging member 2 are respectively provided with end face tooth structures 6, the first engaging member 1 and the second engaging member 2 are used for engagement through the end face tooth structures 6, the end face tooth structure 6 includes a first tooth surface 61 and a second tooth surface 62, and the inclination angle of the first tooth surface 61 is smaller than the inclination angle of the second tooth surface 62;

[0033] Wherein, the first tooth surface 61 is the tooth surface that contacts the first meshing member 1 and the second meshing member 2 when they rotate toward the direction of closing the flip cover 200, and the second tooth surface 62 is the tooth surface that contacts the first meshing member 1 and the second meshing member 2 when they rotate toward the direction of opening the flip cover 200. The inclination angle of the first tooth surface 61 is the acute angle formed by the first tooth surface 61 and the plane perpendicular to the axis of the clutch shaft 3, and the inclination angle of the second tooth surface 62 is the acute angle formed by the second tooth surface 62 and the plane perpendicular to the axis of the clutch shaft 3.

[0034] It should be noted that the flip cover 200 can be an electric fuel tank cover or an electric charging port cover. In other words, the clutch mechanism 100 of this utility model is applicable to fuel vehicles, pure electric vehicles and hybrid vehicles.

[0035] Specifically, the first engaging member 1 can be directly connected to the rotating shaft 210 of the flip cover 200, or it can be connected to the rotating shaft 210 of the flip cover 200 through the transmission gear set 400, or it can be the rotating shaft 210 itself. In practical applications, the design can be selected according to needs, and no specific limitation is made here. The second engaging member 2 and the clutch shaft 3 are usually connected by an internal and external spline structure to achieve transmission and sliding connection. Both the first engaging member 1 and the second engaging member 2 are provided with end face tooth structure 6, and the first engaging member 1 and the second engaging member 2 are engaged through the end face tooth structure 6. The transmission connection between the clutch shaft 3 and the drive motor 300 can be understood as the clutch shaft 3 constituting the motor shaft of the drive motor 300, or the clutch shaft 3 and the motor shaft of the drive motor 300 are connected by, for example, a coupling or a spline structure. When the flip cover 200 is opened electrically, the drive motor 300 drives the clutch shaft 3 to rotate forward, causing the second meshing member 2 and the first meshing member 1 to rotate forward together. At the same time, this rotational motion is transmitted to the rotating shaft 210 of the flip cover 200 via the transmission gear set 400, thereby causing the flip cover 200 to rotate and open. When the flip cover 200 is closed electrically, the drive motor 300 drives the clutch shaft 3 to rotate in reverse, causing the second meshing member 2 and the first meshing member 1 to rotate in reverse together. At the same time, this rotational motion is transmitted to the rotating shaft 210 of the flip cover 200 via the transmission gear set 400, thereby causing the flip cover 200 to rotate and close.

[0036] More specifically, the end face tooth structure 6 includes a first tooth surface 61, a tooth tip surface 63, a second tooth surface 62, and a tooth root surface 64 connected end to end in sequence. The first tooth surface 61 and the second tooth surface 62 are tooth surfaces between the tooth tip surface 63 and the tooth root surface 64, and the tooth surface is usually a plane. The tooth tip surface 63 and the tooth root surface 64 can be either a plane or a curved surface. When the first meshing member 1 and the second meshing member 2, which are engaged by the end face tooth structure 6, rotate in the direction of closing the flip cover 200 (i.e., the first meshing member 1 and the second meshing member 2 rotate in reverse), the end face tooth structure 6 on the first meshing member 1 contacts the end face tooth structure 6 on the second meshing member 2 at the first tooth surface 61, but does not contact at the second tooth surface 62. When the first meshing member 1 and the second meshing member 2 rotate in the direction of opening the flip cover 200 (i.e., the first meshing member 1 and the second meshing member 2 rotate clockwise), the end face tooth structure 6 on the first meshing member 1 contacts the end face tooth structure 6 on the second meshing member 2 at the second tooth surface 62, but does not contact at the first tooth surface 61. Furthermore, the first tooth surface 61 is perpendicular to the plane perpendicular to the axis of the clutch shaft 3 (i.e., the plane perpendicular to the axis of the clutch shaft 3). Figure 2 The acute angle formed by the setting plane 7 (i.e., the inclination angle of the first tooth surface 61) is smaller than the acute angle formed by the second tooth surface 62 and the setting plane 7 (i.e., the inclination angle of the second tooth surface 62). In other words, the inclination angle of the first tooth surface 61 relative to the setting plane 7 is smaller than the inclination angle of the second tooth surface 62 relative to the setting plane 7.

[0037] When assembled, the first meshing member 1 and the second meshing member 2 are engaged with each other through the end face tooth structure 6. When the user manually closes the flip cover 200, the flip cover 200 causes the first meshing member 1 to rotate, but the clutch shaft 3 remains stationary because the drive motor 300 is not started, so the second meshing member 2 does not rotate; that is, when the user manually closes the flip cover 200, the first meshing member 1 rotates relative to the second meshing member 2. During this process, when the end face tooth structure 6 on the first meshing member 1 rotates from contact with the first tooth surface 61 of the end face tooth structure 6 on the second meshing member 2 to contact with the tooth tip surface 63 of the end face tooth structure 6 on the second meshing member 2, because the second meshing member 2 does not rotate, the second meshing member 2, under the pushing action of the first meshing member 1, moves along the clutch shaft 3 in a direction away from the first meshing member 1 (i.e., Figure 5 (The Z-axis moves in the opposite direction) When the end face tooth structure 6 on the first meshing member 1 rotates away from the tooth tip surface 63 of the end face tooth structure 6 on the second meshing member 2, the second meshing member 2 moves upward under the pushing action of, for example, the elastic member 4 (i.e., the Z-axis moves in the opposite direction). Figure 5 The tooth moves in the positive direction of the Z-axis, so that the end face tooth structure 6 on the first meshing member 1 comes into contact with the tooth root surface 64 of the end face tooth structure 6 on the second meshing member 2, thus completing a skip tooth.

[0038] In this embodiment, the clutch mechanism 100 can be provided with end face tooth structures 6 on the first meshing member 1 and the second meshing member 2 respectively, so that the first meshing member 1 and the second meshing member 2 can be meshed through the end face tooth structures 6. At the same time, by drivingly connecting the first meshing member 1 to the rotating shaft 210 of the flip cover 200, and drivingly connecting the second meshing member 2 to the drive motor 300 through the clutch shaft 3, the drive motor 300 can transmit the rotational motion it generates to the rotating shaft 210 of the flip cover 200 through the clutch mechanism 100, thereby realizing the automatic opening or closing of the flip cover 200. Furthermore, by designing the inclination angle of the first tooth surface 61 of the end face tooth structure 6 to be smaller than the inclination angle of the second tooth surface 62 of the end face tooth structure 6, the inclination angle of the contact surface of the end face tooth structure 6 in the closing direction of the flip cover 200 is smaller than the inclination angle of the contact surface of the end face tooth structure 6 in the opening direction of the flip cover 200. In this way, when the user manually closes the flip cover 200, the torque applied by the hand to the flip cover 200 will be smaller than the torque required to open the flip cover 200, thereby reducing the resistance when the user manually closes the flip cover 200, which can improve the convenience of the user manually closing the flip cover 200 and thus improve the user experience.

[0039] Optionally, combined Figure 1 and Figure 2As shown, the first tooth surface 61 and the adjacent second tooth surface 62 are smoothly connected by an arc surface. That is, the tooth tip surface 63 and tooth root surface 64 of the end face tooth structure 6 are arc surfaces, and the tooth tip surface 63 and tooth root surface 64 are smoothly connected to the adjacent first tooth surface 61 or second tooth surface 62. In this way, when the flip cover 200 is manually closed, the end face tooth structure 6 on the first engaging member 1 can make continuous and smooth contact with the end face tooth structure 6 on the second engaging member 2, which helps to reduce, for example, a "clunking" sound, and thus reduces abnormal noise.

[0040] Optionally, combined Figure 1 and Figure 5 As shown, the clutch mechanism 100 also includes an elastic element 4, which is disposed on the side of the second engagement member 2 away from the first engagement member 1, and is used to provide an elastic force to the second engagement member 2.

[0041] Specifically, the two axial ends of the elastic element 4 abut against the second engaging element 2 and the clutch shaft 3, respectively. Multiple elastic elements 4 are typically provided, which can be sequentially sleeved on the clutch shaft 3 or spaced apart circumferentially along the clutch shaft 3. After assembly, the elastic elements 4 are typically in a compressed state to provide a certain initial preload for engagement between the first engaging element 1 and the second engaging element 2, ensuring a tight fit between them. The elastic element 4 is typically a spring structure, which can be a common helical spring or a wave spring; no specific limitation is made here. During the process of the user manually closing the flip cover 200, when the second engaging member 2 moves away from the first engaging member 1 along the clutch shaft 3 under the pushing action of the first engaging member 1, the second engaging member 2 will squeeze the elastic member 4. When the end face tooth structure 6 on the first engaging member 1 rotates away from the tooth tip surface 63 of the end face tooth structure 6 on the second engaging member 2, the elastic member 4 pushes the second engaging member 2 to move upward, so that the end face tooth structure 6 on the first engaging member 1 contacts the tooth root surface 64 of the end face tooth structure 6 on the second engaging member 2.

[0042] In this optional embodiment, by providing an elastic element 4 on the clutch shaft 3 in a manner such as sleeve, and by having the elastic element 4 abut against the side of the second engaging member 2 away from the first engaging member 1, the elastic element 4 can provide an elastic force to the second engaging member 2 during the process of the user manually closing the flip cover 200 and causing the first engaging member 1 to rotate relative to the second engaging member 2. This allows the first engaging member 1 to skip teeth relative to the second engaging member 2 and ensures that the first engaging member 1 and the second engaging member 2 are always connected without disengaging, thereby realizing the manual closing function of the flip cover 200.

[0043] Optionally, combined Figure 3 and Figure 5As shown, the clutch shaft 3 is provided with a shoulder structure 31, and the end of the elastic member 4 away from the second meshing member 2 abuts against the shoulder structure 31.

[0044] In this optional embodiment, the shoulder structure 31 is typically positioned in the middle of the clutch shaft 3, and the elastic element 4 is sleeved on the clutch shaft 3 and clamped between the shoulder structure 31 and the second engagement member 2 in a compressed state. Thus, the shoulder structure 31, together with the second engagement member 2, can axially limit the elastic element 4, and also increases the contact area between the elastic element 4 and the clutch shaft 3, ensuring a uniform distribution of the compressive force between the elastic element 4 and the clutch shaft 3, thereby ensuring the smooth operation of the clutch mechanism 100.

[0045] Optionally, combined Figure 1 As shown, the elastic element 4 is a wave spring sleeved on the clutch shaft 3. Since the wave spring is a precision flat wire compression spring, it can save 50% of space compared with ordinary round wire helical springs. Therefore, using a wave spring as the elastic element 4 and sleeved on the clutch shaft 3 can shorten the axial length of the clutch shaft 3 and even the entire clutch mechanism 100, thereby reducing the overall volume of the clutch mechanism 100 and facilitating its installation.

[0046] Optionally, combined Figure 1 As shown, the clutch mechanism 100 also includes a clutch housing 5, which covers the second engagement member 2 and is connected to the clutch shaft 3. One end of the first engagement member 1 is provided with an end face tooth structure 6, and the other end passes through the clutch housing 5 and is connected to the rotating shaft 210 for transmission.

[0047] In this optional embodiment, when the clutch mechanism 100 further includes an elastic element 4, the elastic element 4 is also located within the internal space of the clutch housing 5. The clutch housing 5 and the clutch shaft 3 can be connected by means such as snap-fit ​​or threaded connection. Simultaneously, the clutch housing 5 typically has a through hole 52. One end of the first engaging member 1 engages with the second engaging member 2 through an end face tooth structure 6, and the other end passes through the through hole 52 on the clutch housing 5 and connects to the transmission gear set 400. Furthermore, the first engaging member 1 is rotatably connected to the through hole 52. Thus, by providing the clutch housing 5, the core components of the clutch mechanism 100, such as the first engaging member 1, the second engaging member 2, and the elastic element 4, are protected, preventing foreign objects such as dust or stones from entering the engagement area of ​​the first engaging member 1 and the second engaging member 2, thereby extending the service life of the core components of the clutch mechanism 100.

[0048] Optionally, combined Figure 1 and Figure 5As shown, the first meshing member 1 includes a meshing part 11 with an end face tooth structure 6 and a connecting shaft part 12 for transmission connection with the rotating shaft 210. The connecting shaft part 12 is located at the end of the meshing part 11 away from the second meshing member 2 and coincides with the central axis of the meshing part 11. The end face of the meshing part 11 away from the second meshing member 2 abuts against the clutch housing 5.

[0049] In this optional embodiment, the engaging portion 11 and the connecting shaft portion 12 of the first engaging member 1 are generally cylindrical. The through hole 52 on the clutch housing 5 can be a circular through hole or a through hole with a polygonal or other geometric shape. When the through hole 52 is a circular hole, its diameter is slightly larger than the outer diameter of the connecting shaft portion 12. When the through hole 52 is a non-circular hole, its opening area is larger than the cross-sectional area of ​​the connecting shaft portion 12. This facilitates assembly and prevents interference when the connecting shaft portion 12 rotates relative to the clutch housing 5, ensuring that the first engaging member 1 can rotate relative to the second engaging member 2. Furthermore, the outer diameter of the engaging portion 11 is larger than the outer diameter of the connecting shaft portion 12. During assembly, the end face of the engagement part 11 away from the second engagement member 2 abuts against the end face of the clutch housing 5 with the through hole 52. In this way, the clutch housing 5 can limit the axial end of the first engagement member 1, ensuring that the first engagement member 1 can push the second engagement member 2 at its other end to move when the flip cover 200 is manually closed.

[0050] Furthermore, the connecting shaft 12 is configured as the rotating shaft 210 of the flip cover 200. In this way, components such as the transmission gear set 400 and the rotating shaft 210 can be eliminated, thereby reducing the overall size and production cost of the actuator of the flip cover 200.

[0051] Optionally, the clutch housing 5 is snapped into the clutch shaft 3. This arrangement facilitates the assembly of the clutch housing 5 and the clutch shaft 3, and also improves assembly efficiency.

[0052] Optionally, combined Figure 1 and Figure 4 As shown, one end of the clutch housing 5 is provided with a pawl 51, and the clutch shaft 3 is provided with a groove 32, and the pawl 51 is engaged in the groove 32.

[0053] In this optional embodiment, the slot 32 can be disposed on the shaft body of the clutch shaft 3 or on the shoulder structure 31 of the clutch shaft 3. In practical applications, it is generally preferred that the slot 32 be disposed on the shoulder structure 31 to ensure the structural strength of the clutch shaft 3 at the shaft body while machining the slot 32. Moreover, the clutch housing 5 is usually provided with a plurality of evenly distributed claws 51, and correspondingly, the shoulder structure 31 is provided with the same number of slots 32 to ensure a firm engagement. In this way, the engagement between the clutch housing 5 and the clutch shaft 3 is achieved by using the claws 51 and the slots 32, which is not only simple in structure and easy to manufacture, but also provides a firm connection.

[0054] Optionally, combined Figure 1 As shown, the second meshing member 2 is splinedly connected to the clutch shaft 3.

[0055] In this optional embodiment, an internal spline 21 may be provided on the second meshing member 2, and an external spline 33 may be provided on the clutch shaft 3, such as... Figure 1 As shown; alternatively, an external spline 33 can be provided on the second meshing member 2, and an internal spline 21 can be provided on the clutch shaft 3. In this case, the second meshing member 2 typically includes a gear portion with an end face tooth structure 6 and an external spline portion connected to the clutch shaft 3, and the elastic member 4 abuts against the end face of the gear portion away from the external spline portion. In practical applications, the design can be selected according to needs, and no specific limitation is made here. In this way, by spline-connecting the second meshing member 2 and the clutch shaft 3, not only can the two be axially slidingly connected, but the smooth transmission of torque can also be ensured. Moreover, the structure is simple and easy to manufacture.

[0056] This utility model provides a vehicle including the clutch mechanism 100 as described above.

[0057] In this embodiment, the vehicle includes not only the clutch mechanism 100, but also a flip-up cover 200 serving as a charging port cover or a fuel tank cover, a drive motor 300, and a transmission gear set 400, such as Figure 5 As shown, the clutch shaft 3 of the clutch mechanism 100 is connected to the drive motor 300. The first engaging member 1 of the clutch mechanism 100 is connected to the rotating shaft 210 of the flip cover 200 through the transmission gear set 400. Moreover, the drive motor 300, the clutch mechanism 100 and the transmission gear set 400 constitute an actuator assembly. This actuator assembly is usually installed on the side of the vehicle body and located inside the charging port cover or fuel tank cover, and is used to drive the charging port cover or fuel tank cover to automatically close or open.

[0058] Furthermore, the beneficial effects of the vehicle in this embodiment compared to the prior art are the same as those of the clutch mechanism described above, and will not be repeated here.

[0059] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
