Description

Unidirectional locking actuator and locking method thereof
Technical Field
The invention belongs to the technical field of driving locking, and particularly relates to a unidirectional locking actuator and a locking method thereof.
Background
The automobile has become a main transportation tool of people, the automobile industry is an important driving force for the economic development of China, the development of national economy is greatly promoted, along with the development of society, new energy automobiles such as electric automobiles and hybrid electric automobiles are more and more commonly used, a charging port cover on the new energy automobiles is an important part of the automobile and is used for replacing a fuel port cover of the fuel automobile, and the common actuator on the market at present generally adopts a motor-driven reduction gear set to start a car door, a carriage and the like so as to realize automatic opening and closing.
In general, motors used in commercial automobiles are roughly of two types:
the first is the motor with self-locking function, this motor passes through worm gear and worm transmission, and the helix angle of worm is less than the friction angle of worm wheel and worm contact surface, can control the rotation under the motor circular telegram condition, because the helix angle of worm is less than the friction angle of worm wheel and worm contact surface, consequently auto-lock under the outage condition, and the motor can not rotate, and the gear of output also can not rotate. However, the motor with the self-locking function cannot unlock the self-locking under the fault condition, so that the door, the carriage and the like cannot be opened easily, and potential safety hazards exist. Meanwhile, due to the structural characteristics of one-way transmission of the worm gear and the worm, the small door cannot be operated at all, including manual opening or manual closing. Similarly, if the small door is opened after charging, the small door can be closed only by restarting the motor, and the small door cannot be closed by people. At this time, the situation that the small door is forgotten to be closed or the manual closing of the small door is performed by a lost hand misoperation, so that the motor is damaged may be caused. Similarly, if the door is opened during a power failure, if the door is forcibly closed by external force, damage to the worm gear and further damage to the actuator may occur.
The second type is the motor without self-locking function, namely the actuator with a multi-stage spur gear transmission structure is adopted, the motor can be controlled to rotate under the condition of electrifying and can also rotate under the condition of de-electrifying, but at the moment, the filler cap or the charging cap can be manually pulled off hard or the automobile jolts in the driving process, the cap is easily pulled off by centrifugal force, great potential safety hazards exist, and the motor can not be used in the environment needing self-locking and theft prevention.
To sum up, the requirements of the market at present for the charging port cover of the electric automobile are as follows: 1. the small door is not required to be opened or closed, but the requirement that the small door is not automatically thrown away in the high-speed running process of the automobile and is not opened by people without being attended by people when the automobile is flameout and stopped is met, and electricity stealing or other damages are carried out. 2. If the power is cut off when the small door is opened, the small door still needs to be closed manually. However, the structure of the current actuators on the market cannot be satisfied at the same time.

And a motor 3, a speed regulating component and a transmission component are arranged in the actuator shell. The actuator housing is also provided with a circuit board 21 for connecting with external signals, and the circuit board 21 is electrically connected with the motor 3.
The motor 3 provides driving force for the actuator; the speed regulating component is connected with an output shaft of the motor 3 and consists of a plurality of gear sets meshed with each other, and is used for regulating the rotation output of the motor 3; one end of the transmission assembly is connected with the speed regulating assembly to provide a medium for the outward output of the driving force of the motor.
The speed regulating assembly comprises a worm gear and a worm rod which are connected with the output shaft of the motor, further, the worm 81 of the worm gear and the worm rod are connected with the output shaft of the motor, and the worm rod further transmits driving force to a worm wheel 83 connected with the worm gear and the worm rod.

The driven shaft 9 comprises a spline shaft 91 and ratchet teeth 92 arranged on one end of the spline shaft 91, wherein the diameter of an circumscribed circle where the ratchet teeth 92 are positioned is larger than that of the circumscribed circle of the spline shaft 91. The ratchet teeth 92 are connected to a lock mechanism 5 provided on the driven shaft side.
The locking mechanism 5 comprises an electromagnetic push rod 41 and a locking pawl 51 connected with the electromagnetic push rod 41, and the locking pawl 51 is pivotally connected with the actuator housing through a shaft pin.
The electromagnetic push rod 41 is connected with the opening on the locking pawl 51 through a pin, one side of the locking pawl 51 is connected with the ratchet teeth 92, and when the electromagnetic push rod 41 works, the locking pawl 51 is shifted, so that the ratchet teeth are driven to rotate.
In this embodiment, the unidirectional transmission component is a unidirectional clutch 62, and the unidirectional transmission component is embedded in a groove 61 on the side surface of the driving gear 6. A groove is correspondingly formed in the other end face of the driving gear 6, a potentiometer 94 is embedded in the groove, and the potentiometer 94 is connected with the center of the driven shaft 9 through a shaft pin.
The middle part of the one-way clutch 62 is provided with a transverse groove 621, the length of the transverse groove 621 is smaller than the diameter of the one-way clutch 62, and a gap is arranged between the two ends of the transverse groove 621 and the inner wall of the side surface groove 61.
The end face openings 625 are formed on the end faces of the one-way clutch at two sides of the transverse groove 621, and a group of friction columns 622 are suspended at the end face openings 625, that is, the friction columns 622 are suspended in the gap between the transverse groove 621 and the inner wall of the side surface groove 61, and the outer surfaces of the friction columns 622 are in contact with the transverse groove 621 and the inner wall of the side surface groove 61. The friction column 622 is used to provide power transmission for the drive gear 6 and the one-way clutch 62. Further, a spring plate 623 is embedded in the end opening 625 of the one-way clutch, and one end of the spring plate 623 is in contact with the friction column 622.
The end face of the driven shaft 9 is convexly provided with a boss 93 matched with the transverse groove 621, the cross section of the boss 93 is shaped like a door, and two ends of the boss 93 are respectively embedded between the friction columns 622.
For a better understanding of the driving relationship between the electromagnetic push rod 41 and the driven shaft 9 and the friction post 622 of the present invention to achieve a one-way drive, it is further explained below in connection with fig. 4-7.
First, it will be appreciated that in active control, the electromagnetic push rod will be remote from the driven shaft 9, i.e. in a non-contact blocking with the driven shaft 9. At this time, the circumferential wall of the friction column 622 and the end face opening 625 of the one-way clutch 62 will generate friction to push the friction column 622, and the friction column 622 will further push the boss 93 interposed between the two friction columns 622, and the boss 93 is connected with the driven shaft, which in turn will push the driven shaft 9 to rotate, outputting a force.
Conversely, when rotated in reverse, typically in the closed condition of the vehicle, the electromagnetic push rod 41 will extend out into contact with the driven shaft 9, again in the absence of electrical power. At this time, the stopping effect is achieved. Specifically, when the driven shaft 9 rotates at this time, the boss 93 pushes the friction column 622, and the friction column 622 compresses the spring plate 623 and then applies force to the one-way clutch 62, thereby driving the driving gear to rotate. However, at this time, the electromagnetic push rod 41 is blocked against the ratchet teeth 92 of the driven shaft 9, so that the driven shaft 9 cannot rotate and can not rotate reversely under the action of the force of the electromagnetic push rod 41. Therefore, the invention can finally achieve the purpose of unidirectional execution.
As a further preferred embodiment, the driven shaft 9 according to the invention employs ratchet teeth 92, i.e. the meshing movement between the ratchet teeth 92 and the battery push rod 41 also achieves that the driven shaft 9 can only rotate in one direction and cannot be reversed.
The invention also discloses a working and locking realization method of the unidirectional locking actuator, which comprises the following steps:
s1, a motor 3 works, and a motor shaft drives a turbine worm to rotate;
s2, the worm and gear drives the driving gear 6 to rotate after the speed of each gear in the speed regulating assembly is regulated;
s3, the driving gear 6 rotates to unidirectionally transmit power to the driven shaft 9 through the unidirectional transmission assembly, and the electromagnetic push rod 41 pushes and pulls the locking pawl at the same time;
s4, transmitting driving force by equipment outside the driven axial actuator shell.
For better unlocking actions, the following description of the abnormal operation procedure of the unidirectional locking when the driven shaft 9 reversely inputs rotation is given: when the motor 3 and the electromagnetic push rod 41 have no power input, the driven shaft 9 is driven to rotate by reverse power input, and the ratchet teeth 91 on the driven shaft 9 push the locking pawl 51 to slightly rotate when the driven shaft 9 rotates, at this time, the driven shaft 9 can rotate. However, when the driven shaft 9 continues to rotate in this direction, the ratchet teeth 91 will press against the locking pawls 51, and the locking pawls 51 will prevent the driven shaft 9 from rotating, so as to achieve the effect of unidirectional rotation and reverse locking of the driven shaft 9. However, if the external driving force of the rotation of the driven shaft 9 exceeds the maximum resistance of the internal limit spring of the electromagnetic push rod, that is, exceeds the maximum pushing force of the electromagnetic push rod, the driven shaft 9 pushes the locking pawl 51 away from the locking position, and at this time, the driven shaft 9 can complete the rotation again.
The following is a further explanation of the principle of implementation in order to combine the technical effects of the present invention:
firstly, the invention adopts multi-gear multi-stage transmission, which can greatly improve the torque output by the motor, and simultaneously, the combination of the electromagnetic push rod and the ratchet wheel is adopted to ensure that the small door is not thrown away. Meanwhile, the one-way clutch is adopted, so that the worm and gear is prevented from being damaged.
Under no power outage (i.e. normal charging door open in charging condition): it can be manually turned off; the principle is as follows: when the door is closed by external force application, the driven shaft 9 transmits force to the friction column 622 through the boss 93, the friction column 622 does not drive the driving gear to rotate, and the friction column 622 rotates, so that the door is closed, and a motor in the actuator and a worm gear in the actuator are protected from being damaged.
If a power failure occurs, the electromagnetic push rod 41 will contact the ratchet teeth 92, and since the ratchet teeth 92 are unidirectional, the electromagnetic push rod can be set to normally rotate without being blocked by the electromagnetic push rod under the condition of closing the small door according to the requirement.
Finally, it should be noted that: the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," and the like refer to an orientation or positional relationship based on that shown in the drawings, merely to facilitate description of the invention and simplify the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
And the above embodiments are only for illustrating the technical solution of the present invention, not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
