Description

Technical Field

[0001] The present application relates to an actuator for a flap and a vehicle comprising the actuator. Background Art

[0002] With the continuous development of the automotive industry, people are increasingly relying on intelligence, which is primarily driven by actuators equipped with motors. Actuators can control fuel filler caps and charging ports on vehicles. Traditional actuators are often directly driven by motors, which open and close the caps.

[0003] Most of these actuators are not self-locking, meaning they can rotate forward and backward and remain free when not powered. Alternatively, they are fully self-locking, using a turbine structure or the motor's built-in self-locking mechanism to prevent the actuator from rotating forward or backward when the power is off. This traditional structure is impractical in many environments. For example, if a fully self-locking actuator is used in the design of an energy filler port assembly, the cover will be completely self-locked when opened and closed, preventing it from rotating. This poses certain safety risks, such as structural damage or injury to others caused by external collisions. Using a fully non-self-locking actuator eliminates the safety risk during opening, but the cover can be easily opened with external force when closed, exposing the energy filler port to the outside, creating additional safety risks and user dissatisfaction. Summary of the Invention

[0004] At least one technical problem to be solved by the present application is to provide a self-locking actuator. The actuator includes: a motor having a motor shaft; a reduction mechanism connected to the motor, the reduction mechanism including a gear mechanism; an output shaft connected to the gear mechanism and driving the flap between an open position and a closed position; a transmission mechanism coupled to the gear mechanism and connected to the motor shaft; and a locking mechanism configured to abut against the gear mechanism to prevent the flap from opening when the flap is in the closed position.

[0005] When the flap is in the closed position, the locking device abuts against the gear device, thereby locking the gear device. When an external force is applied to the flap to open the flap, the gear device does not transmit torque due to the action of the locking device, so the flap remains in the closed position.

[0006] In the above actuator, the locking device includes a first arm and a second arm and is configured so that the first arm and the second arm can rotate around a pivot, the first arm has a locking end, and the second arm contacts a limit device for limiting the moving range of the transmission device on the motor shaft.

[0007] In the above-mentioned actuator, the limit device includes at least one limit assembly, which includes an element in the form of a bearing that can move through the motor shaft and a first spring connected to the element; the end of the second arm abuts against the second bearing; when the locking device enters the locking state, the first spring is compressed; when the locking device enters the unlocking state, the first spring is released.

[0008] In the above actuator, the locking end is configured as a pawl, the gear device includes a ratchet wheel having ratchet teeth, and the pawl can be inserted into a tooth groove between the ratchet teeth.

[0009] In the above actuator, the first arm is connected to a second spring, and when the locking device enters the locking state, the second spring is stretched.

[0010] Another aspect of the present application is to provide an actuator. The actuator includes: a motor having a motor shaft; a reduction mechanism connected to the motor, the reduction mechanism including a gear mechanism; an output shaft connected to the gear mechanism and driving a flap to move between an open position and a closed position; and a transmission connected to the motor shaft and engaged with the gear mechanism, the transmission being configured to move across the motor shaft and to reciprocate on the motor shaft when an external force is applied to the flap in the open position.

[0011] The transmission device can move across the motor shaft, and the motor shaft has a space or travel for the transmission device to move. When the flap is in the open position, an external force is applied to the flap to cause it to rotate toward the closed position. The gear device transmits torque in the opposite direction to the transmission device, causing the transmission device to make a reverse movement on the motor shaft, so that the flap can return to the open position for a period of time, thereby protecting the flap from damage caused by external forces.

[0012] In the above actuator, the transmission device is configured to rotate with the motor shaft and / or move along the motor shaft.

[0013] In the above actuator, the transmission device has a through hole, the motor shaft passes through the through hole, and the through hole has a non-circular cross-sectional shape.

[0014] In the above actuator, the gear device includes a first gear coaxial with the helical gear and a second gear meshing with the first gear, and the second gear is connected to the output shaft.

[0015] In the above actuator, the surface of the transmission device is configured to have worm teeth of a worm, and the gear device at least includes a helical gear meshing with the worm teeth.

[0016] In the above actuator, the gear device includes a first gear coaxial with the helical gear and a second gear meshing with the first gear, and the second gear is connected to the output shaft.

[0017] In the above actuator, the motor shaft has a length that is greater than the length of the transmission device by a distance, and the length of the distance is at least the stroke of the transmission device for performing the return movement.

[0018] The above actuator further includes a limiting device, wherein the limiting device is configured to limit a moving range of the transmission device on the motor shaft.

[0019] In the above actuator, the limiting device includes at least one limiting member configured in the form of a bearing. The actuator further includes a housing in which the motor and the reduction mechanism are installed, and the limiting member is installed in the housing.

[0020] Another aspect of the present application is to provide an actuator that is self-locking in one direction. The actuator includes a motor having a motor shaft; a reduction mechanism connected to the motor, the reduction mechanism including: a gear mechanism; an output shaft connected to the gear mechanism and driving the flap to move between an open position and a closed position; a transmission device engaged with the gear mechanism and connected to the motor shaft, the transmission device being configured to move across the motor shaft and to make a reversal movement on the motor shaft when an external force is applied to the flap in the open position; and a locking device configured to abut against the gear mechanism when the flap is in the closed position to prevent the flap from opening.

[0021] When the cover is subjected to external force in the open position, the gear device transmits reverse torque to the transmission device, and the transmission device makes a return movement on the motor shaft. Therefore, the cover can make a return movement in the open position and is not self-locking; when the cover is subjected to external force in the closed position, the gear device is locked by the locking device and cannot transmit reverse torque. Therefore, the cover is self-locking when closed.

[0022] Another aspect of the present application is to provide a vehicle equipped with the actuator, wherein the vehicle has a flap for energy refueling, and the flap is driven by the actuator.

[0023] The structure of the present invention is simple and reliable. The cover can be automatically opened and closed by the actuator and is self-locked only in the closed position.

[0032] In order to help those skilled in the art to accurately understand the subject matter for which protection is sought in this application, the specific implementation methods of this application are described in detail below with reference to the accompanying drawings.

[0033] Figure 1 This is a schematic diagram of an embodiment of an actuator for a flap involved in this application. The flap 5 is the cover of the energy filling port on a vehicle, also known as a small door, such as the fuel filler cap on a conventional car or the charging port cap on an electric car. When refueling or charging is required, the actuator drives the flap to open, and the refueling or charging operation then proceeds. When the refueling or charging operation is complete, the actuator drives the flap to close.

[0034] The actuator shown in the figure includes a housing 1, a motor 22, a reduction mechanism 3 and a locking device 6. The motor 22 has an output shaft 24 and passes through the housing 1 through the hole 14 into the interior of the housing 1. The reduction mechanism 3 and the locking device 6 are both arranged in the housing 2.

[0035] The reduction mechanism 3 includes a gear device 32, an output shaft 34, and a transmission device 36. The gear device 32 includes a gear pair with at least one transmission ratio to reduce the transmission torque. Figure 1 As shown, the gear device 32 includes a first gear that is hidden and a second gear 44 and a helical gear 46. The first gear 42 and the helical gear 46 are integrated into a gear set, see Figure 2 The gear set is mounted on the first shaft 16 in the housing 1. The first gear 42 and the helical gear 46 have the same rotational speed. The second gear 44 is connected to the output shaft 34 mounted on the housing 1. There is a large transmission ratio between the first gear 42 and the second gear 44. The output shaft 34 is mounted on the cover 5, as shown in FIG. Figure 1 As shown, the cover 5 is mounted on the output shaft 34. When the output shaft 34 rotates, the cover 5 rotates through an angle therewith.

[0036] The transmission device 36 is engaged with the gear device 32. The transmission device 36 is also connected to the motor shaft 24 to establish a torque transmission path between the motor 22 and the reduction mechanism 3. The motor 22 drives the output shaft 34 to rotate via the torque transmission path to open or close the cover 5. The transmission device 36 is configured to pass movably through the motor shaft 24. The transmission device 36 can make a reverse movement on the motor shaft 24. In the illustrated embodiment, the transmission device 36 moves along the motor shaft 24 in a direction away from the motor 22 and can return along the previous movement path. When the torque transmission path is reversed, that is, the gear device 32 transmits torque to the transmission device 36 as the output of torque, because the transmission device 36 can make a reverse movement on the motor shaft 24 toward the motor 22, the torque transmission path is cut off, so the reverse torque will not be transmitted to the motor 22.

[0037] The transmission device 36 can rotate together with the motor shaft 24 and / or move linearly relative to the motor shaft 24. When the motor shaft 24 rotates, the transmission device 36 can rotate together; alternatively, when the motor shaft 24 rotates, the transmission device 36 can rotate and move along the motor shaft 24; alternatively, when the motor shaft 24 rotates, the transmission device 36 can move along the motor shaft 24. Whether the motor 22 rotates forward or reverse, torque can be transmitted to the gear device 32 via the transmission device 36.

[0038] The transmission device 36 includes worm teeth 38 of a worm gear disposed on its surface, with a through hole 40 defined in the center. The transmission device 36 is sleeved onto the motor shaft 24 via the through hole 40. The motor shaft 24 engages with the through hole 40. The through hole 40 is a semicircular hole, and the portion of the motor shaft 24 that engages with the through hole 40 is configured in a semicircular shape. The through hole 40 can be designed into other shapes, or the motor shaft 24 and the transmission device 36 can be otherwise mated, such as with a key. The worm teeth 38 mesh with a helical gear 46. The transmission device 36 and the helical gear 46 provide primary torque reduction for the motor 22.

[0039] The transmission device 36 moves along the motor shaft 24 for a certain distance, so the length of the motor shaft 24 needs to be designed to be longer to meet the travel requirements of the return movement of the transmission device 36. A limit device is provided on the motor shaft 24 to limit the movement range of the transmission device 36. A limit member 72 is provided at the position of the end of the motor shaft 24 relative to the housing 1 to determine an extreme position of the movement of the transmission device on the motor shaft. Another "limit member" is also provided on a section of the motor shaft 24 close to the motor 22. In the illustrated embodiment, the "limit member" is a limit assembly 74, which cooperates with the locking device 6 to set another extreme position for the transmission device 36. The transmission device 36 is located between the limit member 72 and the limit assembly 74.

[0040] The limiter 72 is constructed in the form of a bearing. A sleeve 18 aligned with the motor shaft 24 is provided in the housing 1. A hole is provided on the sleeve 18, which is inserted when the motor shaft 24 is installed. A limiter 72 is provided on the end of the sleeve 18. When the transmission device 36 moves to contact the limiter 72, the limiter 72 restricts the transmission device 36 from moving further, and the setting of the limiter 72 also avoids direct friction contact between the transmission device 36 and the sleeve 18. The limiter 72 can also be provided on the motor shaft 24. The limiter assembly 74 includes a bearing-shaped element 741 and a first spring 76 sleeved on the motor shaft, one end of the first spring 76 is connected to the element 741, and the other end is fixed to the wall of the housing 1. The element 741 is movable on the motor shaft 24, and the first spring 76 applies a rebound force to the transmission device 36 through the element 741 to move toward the limiter 72. The element 741 can be omitted or replaced by other parts. Alternatively, when the actuator does not require a locking device, the limiting assembly may be a bearing fixed relative to the motor shaft, similar to the limiting member.

[0041] As mentioned above, the limiting assembly 74 cooperates with the locking device 6 to function. Next, the locking device 6 is introduced. Figure 3The locking device 6 is positioned near the gear assembly 32. It is configured to abut against the gear assembly 32 to prevent rotation. When the gear assembly 32 is unable to rotate, the flap 5 enters a self-locking state, thus activating the locking device 6 when the flap 5 is in the closed position. The locking device 6 is provided with a pawl to prevent rotation of the gear assembly 32 in one direction. The locking device 6 comprises a body 62 with a central pivot hole and a first arm 64 and a second arm 66. The end of the first arm 64 is configured as a locking end with a pawl 68. Correspondingly, a ratchet 48 is also provided on the gear train to engage with the pawl 68. The ratchet 48 rotates at the same speed as the bevel gear 46 and the first gear 42. When the pawl 68 is inserted into one of the tooth grooves on the ratchet 48, it restricts rotation of the ratchet 48, thereby limiting rotation of the gear train in one direction, while not affecting rotation of the ratchet 48 or even the gear train in the opposite direction.

[0042] The locking device 6 is mounted on the second shaft 17 within the housing 1 via a pivot hole, forming a lever. A second arm 66 extends near the stop assembly 74 and can abut against element 741. When element 741 moves toward the motor 22, it pushes the second arm 66, causing the locking device 6 to rotate clockwise around the second shaft 17 as shown. Simultaneously, the pawl 68 on the first arm 64 gradually approaches the ratchet 48. Once the pawl 68 engages the ratchet 48, it resists against the ratchet 48, locking it. A second spring 69 is also connected to the first arm 64, the other end of which is connected to the wall of the housing 1. When the pawl 68 disengages from the ratchet 48, the second spring 69 forces the locking device 6 to reverse.

[0043] Next, the working process of the actuator involved in this application is introduced.

[0044] Figure 4-6 The figure shows three typical operating states of the actuator involved in this application. When the motor 22 is started, the motor shaft 24 rotates, driving the transmission device 36 through the semicircular through-hole. At this point, the pawl 68 disengages the ratchet 48, allowing the transmission device 36 to rotate the helical gear 46 meshing with the worm gear 38 of the transmission device 36. The helical gear 46 then rotates the first gear 42, which it conceals, and meshes with the second gear 44. Ultimately, the output shaft 34 drives the cover 5 to pivot open from the closed position.

[0045] The flap 5 is equipped with a limiter mechanism that restricts its movement or rotation within a specified range. Once the flap 5 has moved to a certain extent, such as when opening by rotating as shown, the limiter mechanism restricts further rotation of the flap 5 after a certain angle of rotation. Consequently, the output shaft 34, second gear 44, first gear 42, and bevel gear 46 all stop rotating. While the motor remains in operation, the torque transmission path changes because the bevel gear 46 is not rotating. Rotation of the transmission 36 is converted into movement of the transmission 36 along the motor shaft 24 toward the limiter 72.

[0046] Continue to see Figure 4 When the transmission device 36 contacts the stopper 72, it stops moving forward, and the motor 22 enters an idle state, eventually stopping. Due to the rebound force of the first spring 76, the element 741 moves along with the transmission device 36 toward the stopper 72. The transmission device 36 is constrained between the stopper 72 and the element 741 (and the first spring 76).

[0047] At this time, if a reverse external force is applied to the flap 5, that is, to rotate the flap toward the closed position, the output shaft 34 rotates in the reverse direction, and then the second gear 44 becomes the driving wheel, driving the first gear 42 to reverse, and then the helical gear 46 to reverse. Under the meshing of the helical gear 46 and the transmission device 36, although the transmission device 36 cooperates with the motor shaft 24, it cannot rotate and can only move linearly along the motor shaft 24 toward the direction of the element 741, that is, it moves downward while squeezing the first spring 76. Figure 5 Once the external force on the cover 5 is removed, the first spring 76 acts to urge the transmission device 36 to move toward the limit member 72 again in the direction of the dotted arrow, and the bevel gear 46, the first gear 42, the second gear 44 and the output shaft 34 rotate forward until the cover 5 returns to its original open position. Figure 4 Status shown.

[0048] When the motor 22 rotates in the opposite direction, the transmission device 36, the bevel gear 46, the first gear 42, the second gear 44, and the output shaft 34 all rotate in the opposite direction, thereby driving the cover 5 to rotate from the open position to the closed position. Due to the action of the limiting mechanism, when the cover 5 returns to the closed position, the output shaft is restricted and will no longer rotate, so the output shaft 34, the second gear 44, the first gear 42, and the bevel gear 46 stop rotating. At this time, the motor 22 continues to rotate, and the transmission device 36 moves along the motor shaft 24 toward the element 741 while rotating. The element 741 moves along the motor shaft 24 together with the transmission device 36, as shown in FIG. Figure 6 Indicates the downward direction.

[0049] Element 741 presses against second arm 66 of locking mechanism 6 and continues to move. Locking mechanism 6 rotates clockwise around second axis 17 as shown. Pawl 68 on first arm 64 gradually approaches ratchet 48 until it engages the ratchet teeth, locking ratchet 48. Second spring 76 is tensioned. Transmission 36 stops moving. Motor 22 enters idle mode and stops operating. If a reverse external force is applied to flap 5 at this point, torque transmission to bevel gear 46 is blocked and interrupted by the resistance of pawl 68 against ratchet 48. Therefore, flap 5 cannot be opened in the closed position.

[0050] If the actuator is to open the cover 5 and the motor 22 is reactivated, the bevel gear 46 is initially undriven due to the engagement of the pawl 68 with the ratchet 48. The torque output from the motor shaft 24 drives the transmission 36 to rotate and move along the motor shaft 24 toward the stopper 72. Once the transmission 36 moves in the upward direction shown, the element 741 moves upward with the transmission 36 due to the release of the transmission 36 and the force of the first spring 76. The pressure applied to the second arm 66 is then removed. Under the action of the first spring 76, the locking device 6 immediately rotates counterclockwise, disengaging the pawl 68 from the ratchet 48, and the actuator returns to its normal open position. The bevel gear 46 can then be driven again by the transmission 36 to transmit torque, opening the cover 5.

[0051] While specific embodiments of the present application have been shown and described in detail to illustrate the principles of the present application, it will be appreciated that the present application may be embodied in other ways without departing from such principles.
