The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.
Referring to fig. 1 to 3, an actuator 100 for a charge door of an electric car according to a preferred embodiment of the present utility model will be described in detail. The actuator 100 for a trolley charging door includes a housing 10, a driving assembly 20, and an output assembly 30.
The drive assembly 20 is provided in the housing 10.
The output assembly 30 includes an output gear 31 and an output shaft 32. The output gear 31 is connected to the driving unit 20, the output gear 31 is formed with an axial hole 3101 extending in the axial direction, and a groove 3102 communicating with the axial hole 3101 is formed at one end. The output shaft 32 has an axial portion 321 and a radial portion 322 extending radially outwardly along the axial portion 321, and the axial portion 321 is sleeved in the axial hole 3101 through the groove 3102 and adapted to be connected to a trolley charging door (not shown). The driving assembly 20 is configured to drive the output gear 31 to rotate around an axis thereof, and the output gear 31 rotates to drive the axial portion 321 of the output shaft 32 to output torque to the electric car charging door connected with the output gear, so as to drive the electric car charging door to rotate, and further open or close the electric car charging door, thereby achieving the purpose of exposing or hiding the electric car charging interface. That is, when the customer uses the electric car charging door, the customer can normally open or close the electric car charging door by starting the driving assembly 20, driving the output gear 31 to rotate around its axis through the driving assembly 20, and driving the axial portion 321 of the output shaft 32 to rotate through the rotation of the output gear 31, thereby driving the electric car charging door connected to the axial portion 321 of the output shaft 32 to rotate.
In the case of a failure of the driving assembly 20, a customer may manually rotate the electric car charging door, and since the radial portion 322 of the output shaft 32 is placed in the groove 3102 and the radial portion 21 is rotated to not drive the output gear 31 to rotate, when the electric car charging door is manually rotated to drive the output shaft 32 to rotate, the output shaft 32 freely rotates in the axial hole 3101 and the groove 3102, the electric car charging door can be smoothly manually opened or closed, and the output gear 31 and the driving assembly 20 are not damaged when the output shaft 32 is manually rotated.
In this way, in the case of the failure of the driving assembly 20, the actuator 100 of the present utility model can still open or close the electric car charging door, which has strong applicability, and can ensure that the driving assembly 20 and the output gear 31 are not damaged when the electric car charging door is manually rotated to open or close.
According to some preferred embodiments of the present utility model, referring to fig. 2, a mounting cavity 101 is formed in the housing 10, and the driving assembly 20 and the output assembly 30 are disposed in the mounting cavity 101. In this way, the housing 10 can play a role in preventing water and dust for the output assembly 30 and the driving assembly 20, and better protect the output assembly 30 and the driving assembly 20, so that the output assembly and the driving assembly can have a longer service life.
Further, referring to fig. 2, the housing 10 includes an upper shell 11 and a lower shell 12. The upper shell 11 and the lower shell 12 are detachably spliced to form the housing 10. This facilitates disassembly of the housing 10 and assembly of the output assembly 30 and the drive assembly 20 within the housing 10.
According to some preferred embodiments of the present utility model, the driving assembly 20 includes a driving motor 21, and the driving motor 21 is immovably fixed to the housing 10 and connected to the output gear 31 for driving the output gear 31 to rotate. In this way, under normal conditions, the customer may drive the output gear 31 to rotate around its axis by starting the driving motor 21, and under the condition that the driving motor 21 fails, the customer may manually rotate the electric car charging door, because the radial portion 322 of the output shaft 32 is placed in the groove 3102, the friction force generated between the radial portion 322 of the output shaft 32 and the output gear 31 cannot drive the output gear 31 and the driving motor 21 to rotate, so that the radial portion 21 rotates without driving the output gear 31 to rotate, and the output shaft 32 can freely rotate in the axial hole 3101 and the groove 3102 without driving the output gear 31, so that the electric car charging door can be smoothly opened or closed manually.
According to further preferred embodiments of the present utility model, referring to fig. 2 and 4, the drive assembly 20 further includes a worm 22 and a worm wheel 23. The driving motor 21 is connected with the worm 22, the worm 22 is meshed with the worm wheel 23, and the worm wheel 23 is connected with the output gear 31. The driving motor 21 is used for driving the worm 22 to rotate, the worm 22 drives the worm wheel 23 to drive the output gear 31 to rotate around the axis of the output gear, and the worm wheel 23 does not drive the worm 22 to rotate.
In this way, by utilizing the self-locking characteristic of the worm wheel 23 and the worm 22, that is, the rotation of the worm 22 can drive the worm wheel 23 to rotate, but the rotation of the worm wheel 23 cannot drive the worm 22 to rotate, so that even if the output gear 31 rotates to drive the worm wheel 23 to rotate due to accidents or the failure of the matching of the output shaft 32 and the output gear 31, the worm 22 still cannot rotate, the trolley charging door can still be opened or closed manually, the driving motor 21 still cannot be damaged, and the driving motor 21 can be protected.
According to further preferred embodiments of the present utility model, referring to fig. 4, the driving assembly 20 further includes a first stage transmission assembly 24, a second stage transmission assembly 25 and a third driving spur gear 26, the first stage transmission assembly 24 includes a first driving spur gear 241 and a first driven spur gear 242, the first driving spur gear 241 and the worm wheel 23 are coaxially connected and meshed with the first driven spur gear 242, and the first driving spur gear 241 has an outer diameter smaller than the first driven spur gear 242 and the worm wheel 23.
The second stage transmission assembly 25 includes a second driving spur gear 251 and a second driven spur gear 252, the second driving spur gear 251 is coaxially connected to the first driven spur gear 242 and meshed with the second driven spur gear 252, and the outer diameter of the second driving spur gear 251 is smaller than that of the first driven spur gear 242 and the second driven spur gear 252.
The third driving spur gear 26 is coaxially connected with the second driven spur gear 252 and is meshed with the output gear 31, the outer diameter of the third driving spur gear 26 is smaller than that of the second driven spur gear 252 and the output gear 31, and when the worm wheel 23 rotates, the output gear 31 is driven to rotate around the axis thereof by rotating all gears in the first stage transmission assembly 24 and the second stage transmission assembly 25 and the third driving spur gear 26.
In this way, the rotational motion output by the driving motor 21 can be transmitted to the output gear 31 after multiple reduction transmissions, so that the transmission is stable, and the transmission efficiency and the appropriate transmission ratio are high.
According to some examples of the present utility model, referring to fig. 4, the first driving spur gear 241 and the worm wheel 23 are integrated on the same part, the first driven spur gear 242 and the second driving spur gear 251 are integrated on the same part, and the second driven spur gear 252 and the third driving spur gear 26 are integrated on the same part, so that the structure is compact and the occupied space is small.
According to some preferred embodiments of the present utility model, referring to fig. 3, the axial portion 321 of the output shaft 32 and the radial portion 322 are integrally formed, such as integrally injection molded. In this way, when assembling the actuator 100 for a trolley charging door, the customer can directly assemble the output shaft 32 to the housing 10 without having to reproduce the field assembly, and the assembly process is fewer and the assembly difficulty is low.
According to some preferred embodiments of the present utility model, referring to fig. 2 and 3, the output assembly 30 further includes an elastic member 33, where the elastic member 33 is disposed between the inner wall of the housing 10 (e.g., the lower housing 12) and the radial portion 322, for abutting the radial portion 322 in the groove 3102 so that the inner wall of the groove 3102 is in contact with the outer wall of the radial portion 322. This arrangement ensures a contact area between the radial portion 322 and the groove 3102, so that the output shaft 32 can be stably and normally rotated by a large frictional force when the output gear 31 is rotated.
Further, the elastic member 33 is configured as a spring, and the output assembly 30 further includes a spacer 34, where the spacer 34 is disposed on the inner wall of the housing 10, and the spring is sleeved outside the axial portion 321 of the output shaft 32 and between the spacer 34 and the radial portion 322, so as to abut the radial portion 322 in the groove 3102.
Further, a groove 3102 is provided along the output gear 31 from one end face thereof to the other end face thereof, and an inner diameter of the groove 3102 and an outer diameter of the radial portion 322 gradually decrease. The inclined surface can increase the contact area between the radial portion 322 and the groove 3102, so as to increase the friction between the output gear 31 and the output shaft 32, so that the output shaft 32 can be smoothly driven to rotate when the output gear 31 rotates.
According to some preferred embodiments of the present utility model, referring to fig. 2, the output assembly 30 further includes a magnetic sensor 35, a magnet 36, and a control unit. One of the magnetic sensor 35 and the magnet 36 is immovably provided in the housing 10, the other is provided in the output gear 31 to rotate synchronously with the rotation of the output gear 31, so that when the output gear 31 rotates, the magnetic sensor 35 senses the rotation speed and the rotation angle of the output gear 31 by sensing the magnet 36, and the control unit is connected with the magnetic sensor 35 and is used for controlling the output rotation speed and the output torque of the driving motor 21 according to the rotation speed and the rotation angle of the output gear 31 sensed by the magnetic sensor 35, so that the output rotation speed and the rotation angle of the output gear 31 can be adjusted to meet different demands of different customers.
For example, if the customer considers that the rotation speed and rotation angle of the output gear 31 are too large, the opening and closing speed and rotation angle of the electric car charging door are too large, and the response is not enough when the electric car charging door is used, the customer can control the output rotation speed and output torque of the driving motor 21 to be correspondingly reduced by using the control unit, so that the opening and closing speed and rotation angle of the electric car charging door are correspondingly reduced. If the rotation speed and rotation angle of the output gear 31 are considered to be too small by the customer, the opening and closing speed and rotation angle of the electric car charging door are too small, and the opening and closing efficiency is too low, the customer can control the output rotation speed and output torque of the driving motor 21 to be correspondingly increased by using the control unit, so that the opening and closing speed and rotation angle of the electric car charging door are correspondingly increased, and different use requirements of different customers are met.
In some examples of the present utility model, referring to fig. 2, the magnetic sensor 35 is immovably provided to the housing 10, and the magnet 36 is provided to the output gear 31 to rotate synchronously with the rotation of the output gear 31.
In this way, as the output gear 31 rotates, the magnet 36 disposed on the output gear 31 rotates synchronously with the rotation of the output gear 31, and the magnetic sensor 35 disposed on the housing 10 keeps still, so that the magnetic field strength sensed by the magnetic sensor 35 changes, so that the magnetic sensor 35 can determine the rotation speed and rotation angle of the magnet 36 relative to the stationary magnetic sensor 35 according to the changed magnetic field strength, and the rotation speed and rotation angle of the magnet 36 are consistent with those of the output gear 31, so that the magnetic sensor 35 detects the rotation speed and rotation angle of the output gear 31, and thus, the output states of the output gear 31 and the output shaft 32 can be effectively monitored by the client, and further, the output state can be conveniently and timely adjusted.
Of course, in the present utility model, the magnetic sensor 35 may be provided on the output gear 31 to rotate synchronously with the rotation of the output gear 31, and the magnet 36 may be immovably provided on the housing 10. In this case, the magnetic field intensity sensed by the magnetic sensor 35 changes with the rotation of the output gear 31, so that the magnetic sensor 35 can determine the rotation speed and rotation angle of the magnetic sensor 35 with respect to the stationary magnet 36 according to the changed magnetic field intensity, and the rotation speed and rotation angle when the magnetic sensor 35 rotates coincide with the output gear 31, and thus correspond to the rotation speed and rotation angle when the magnetic sensor 35 detects the output gear 31. In this way, the customer can also effectively monitor the output states of the output gear 31 and the output shaft 32.
Specifically, the magnetic sensor 35 may be a hall sensor, and the control unit may be a control chip.
The present utility model also provides a trolley charging door assembly, which comprises a trolley charging door and an actuator 100 as described above, wherein the axial portion 321 of the output shaft 32 is connected to the trolley charging door, and is used for driving the trolley charging door to rotate, so that the trolley charging door opens or closes a trolley charging interface.
