The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0029] Please refer to Figure 1 - Figure 5The utility model is a lifting and rotating actuator, comprising: an upper shell 2 and a bottom shell 3 that are detachably connected, the upper shell 2 is provided with a through hole 4 and at least one lifting slot 401, and the lifting slot 401 is located on one side of the through hole 4; an output shaft 7, one end of which is connected to a knob and the other end is connected to a screw rod 12, the knob is provided with at least one protrusion 11 along the radial direction, the protrusion 11 is slidably matched with the lifting slot 401, and the knob is used to lock or unlock the upper shell 2 after rotating a certain angle; a driving component and a transmission component connected thereto, which are arranged inside the bottom shell 3, and the transmission component is threadedly matched with the screw rod 12; under the drive of the driving component, when the protrusion 11 is located inside the lifting slot 401, the transmission component drives the output shaft 7 to rise and fall along the lifting slot 401 through relative rotation with the screw rod 12, and when the protrusion 11 is located outside the lifting slot 401, the transmission component drives the output shaft 7 to rotate, thereby driving the knob to lock or unlock the upper shell 2.
[0030] Specifically, the actuator is used to open and close the cover of the automobile product, and includes an upper shell 2 and a bottom shell 3, wherein the upper shell 2 and the bottom shell 3 are enclosed to form a accommodating cavity, and the cavity can accommodate the driving component, the transmission component and the internal circuit components, so that each component is installed inside the shell and keeps a sealed state, so that the actuator has waterproof and dustproof capabilities; one end of the output shaft 7 is connected to the knob, and the knob is radially connected to the protrusion 11, and the protrusion 11 slides with the lifting groove 401 in the upper shell 2, so that the output shaft 7 cannot rotate when moving in the through hole 4, and the internal thread in the transmission component cooperates with the screw rod to rotate relative to each other, so that the output shaft 7 can only be driven to lift; at the same time, the protrusion 11 on the knob can lock or unlock the upper shell 2 after rotating a certain angle, and the simple structure can realize both the lifting and the rotation locking or unlocking of the knob, thereby reducing the accommodating space required for the transmission component, thereby effectively controlling the size of the entire actuator and meeting the miniaturization requirements of the actuator.
[0031] During use, the screw rod 12 on the output shaft 7 cannot rotate due to the engagement limit between the protrusion 11 and the lifting groove 401. At this time, driven by the driving component, the transmission component drives the output shaft 7 to rise and fall along the lifting groove 401 through relative rotation with the screw rod 12; when the protrusion 11 rises to the outside of the lifting groove 401, the protrusion 11 and the lifting groove 401 are released from the limit. At this time, driven by the driving component, the transmission component drives the output shaft 7 to rotate, and then drives the knob to lock or unlock the upper shell 2. The actuator can drive the knob to rise and fall first and then rotate through a driving component, thereby avoiding interference between components during the opening and closing process. The structure is simple and the production cost is greatly reduced.
[0032] In one embodiment of the utility model, at least one limiting groove 10 is provided on a side of the upper shell 2 facing away from the bottom shell 3 , one end of the limiting groove 10 is connected to the lifting groove 401 , and the other end is extended along the circumferential surface of the through hole 4 .
[0033] Specifically, in order to limit the rotation angle of the knob and avoid the situation where the locking cannot be achieved due to excessive rotation of the output shaft 7, the upper shell 2 is also provided with a limiting groove 10, which is arc-shaped and arranged in the horizontal direction, and one end of which is connected to the lifting groove 401, so that when the knob is rising and the protrusion 11 is separated from the lifting groove 401, the protrusion 11 can rotate along the limiting groove 10, and finally rotate to the end of the limiting groove 10 away from the lifting groove 401 and abut against the limiting groove 10 to stop the rotation of the knob, which can effectively avoid the situation where the locking cannot be achieved due to excessive rotation of the output shaft 7, thereby greatly improving the stability of the locking of the upper shell 2.
[0034] In one embodiment of the present invention, the driving assembly includes: a motor 5 which is horizontally arranged inside the bottom shell 3 , and a worm 13 is fixedly connected to the output end of the motor 5 .
[0035] Specifically, the output end of the motor 5 can be integrally connected to the worm 13, welded, or fixedly connected via a coupling, which can effectively ensure the stability of transmission between various internal components.
[0036] In one embodiment of the utility model, the transmission assembly includes: a worm wheel 6, which meshes with the worm 13, and the central axis of the worm wheel 6 is provided with an internal thread; the output shaft 7 is coaxially fixed with a screw 12, and the worm wheel 6 meshes with the screw 12 through the internal thread.
[0037] Specifically, in order to stably transmit the output shaft, the transmission form of the worm wheel 6 and the worm 13 is used to enable the output shaft 7 to stably rotate forward and reverse. The internal thread arranged axially in the center of the worm wheel 6 cooperates with the screw rod 12. When the protrusion 11 on the knob connected to the output shaft 7 is engaged in the lifting groove 401, the output shaft 7 cannot rotate. Therefore, the relative rotation between the internal thread and the screw rod 12 can drive the output shaft 7 to be lifted and lowered. Once the protrusion is separated from the lifting groove 401, the worm wheel 6 will drive the output shaft to rotate when rotating, thereby driving the knob and the protrusion 11 to rotate to lock or unlock the upper shell 2. A driving component and a transmission component are cleverly realized to drive the output shaft 7 to be lifted and lowered and rotated in sequence, reducing the accommodation space required for the transmission component, thereby effectively controlling the size of the entire actuator, meeting the miniaturization requirements of the actuator, and avoiding interference between the components during the opening and closing process. The structure is simple, the production cost is greatly reduced, and the user experience is greatly improved.
[0038] In one embodiment of the present invention, the driving assembly includes: a motor 5, which is coaxially arranged at the bottom of the output shaft 7, and the output shaft of the motor 5 is fixedly connected with a threaded sleeve.
[0039] Specifically, the output end of the motor 5 can be integrally connected to the threaded sleeve, welded, or fixedly connected via a coupling, which can effectively ensure the stability of transmission between various internal components.
[0040] In one embodiment of the present invention, a screw rod 12 is coaxially fixedly disposed on the output shaft 7 , and the threaded sleeve is meshed with the screw rod 12 .
[0041] Specifically, the internal thread in the threaded sleeve cooperates with the screw rod 12, and when the protrusion 11 on the knob connected to the output shaft 7 is engaged in the lifting groove 401, the output shaft 7 cannot rotate. Therefore, the relative rotation between the internal thread and the screw rod 12 can drive the output shaft 7 to rise and fall. Once the protrusion is disengaged from the lifting groove 401, the threaded sleeve will drive the output shaft to rotate when rotating, thereby driving the knob and the protrusion 11 to rotate to lock or unlock the upper shell 2. A driving component and a transmission component are cleverly realized to drive the output shaft 7 to rise and fall and rotate in sequence, reducing the accommodating space required for the transmission component, thereby effectively controlling the size of the entire actuator, meeting the miniaturization requirements of the actuator, and avoiding interference between components during the opening and closing process. The structure is simple, the production cost is greatly reduced, and the user experience is greatly improved.
[0042] One embodiment of the utility model further includes: a retaining ring, which is coaxially arranged on the outer side of the output shaft 7 and movably connected to the output shaft 7, the retaining ring 8 is fixedly provided with a retaining plate in the radial direction, the bottom shell 3 is located on the outer side of the retaining ring 8 and is also provided with an arc-shaped enclosure, one end of the retaining plate extends to the outside of the arc-shaped enclosure to limit the rotation angle of the retaining ring; a nut 9, which is coaxially arranged on the outer side of the output shaft 7 and fixedly connected to the output shaft 7, and the nut 9 is located on the side of the retaining ring 8 away from the knob.
[0043] Specifically, since the rotation of the output shaft 7 needs to be driven by the motor 5 and the transmission assembly, it is inevitable that the rotation angle of the knob will be offset due to factors such as vibration during the movement of the car. In this application, a retaining ring 8 and a nut 9 are provided. The retaining ring 8 is fixedly provided with a retaining piece in the radial direction. The bottom shell 3 is located on the outer side of the retaining ring 8 and is further provided with an arc-shaped enclosure. One end of the retaining piece extends to the outside of the arc-shaped enclosure. When the protrusion 11 is separated from the lifting groove 401, the nut 9 and the retaining ring 8 are in In the tightened state, when the knob is rotated to lock the upper shell 2, the blocking piece abuts against one side of the arc-shaped enclosure, and the retaining ring 8 and the blocking piece are respectively tightened to further increase the damping of the knob in the horizontal direction, thereby increasing the locking stability; when the knob is unlocked, the blocking piece rotates to the other side of the arc-shaped enclosure. At this time, if the output shaft drives the nut to continue to rotate, it will separate from the blocking piece, and then drive the protrusion 11 of the knob on the output shaft to enter the lifting slot 401. This setting method has a simple structure and can meet the functions required by users.
[0044] In one embodiment of the present invention, the number of the protrusion 11 and the number of the limiting groove 10 are both two, and both are symmetrically arranged along the axial center of the output shaft 7 .
[0045] Specifically, the number of the protrusions 11 and the limiting grooves 10 can be selected according to user needs. Multiple protrusions 11 correspond to the limiting grooves 10 one by one, and the greater the number, the more stable it is, but it also makes the structure complex and increases the cost. Users can choose the setting according to their needs.
[0046] One embodiment of the present invention further includes: a circuit board 14 which is electrically connected to the motor 5 .
[0047] Specifically, the actuator has an electric function through the electrical connection between the circuit board and the motor 5, and realizes the locking or unlocking of the interior of the vehicle through the signal connection with the vehicle equipment, which greatly improves the convenience.
[0048] In one embodiment of the present invention, the limiting angles of the limiting groove 10 and the arc-shaped enclosure are both 90°.
[0049] Specifically, the number of the protrusions 11 and the limiting grooves 10 can be selected according to user needs. Multiple protrusions 11 correspond to the limiting grooves 10 one by one, and the more the number, the more stable and the smaller the angle, but it also makes the structure complex and the cost increased. Users can choose the setting according to their needs.
[0050] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
