[0032] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] See also Figure 1-8 As shown, an actuator for a charging cover or a fuel filler cover comprises:

[0034] A mounting base 1 is provided with an axially movable lifting shaft 2 and a circumferentially rotatable rotating seat 3, wherein the lifting shaft 2 has a first position state connected with the cover body during the upward movement, and has a second position state disconnected from the cover body during the downward movement;

[0035] The rotating seat 3 is provided with a limiting portion 3.1. When the lifting shaft 2 is in the second position, the rotating seat 3 rotates until the limiting portion 3.1 cooperates with the positioning portion 2.1 on the lifting shaft 2 to position the lifting shaft 2 and limit the lifting shaft 2 from rising.

[0036] The rotating seat 3 is provided with a fitting groove 3.2, and the mounting base 1 is also provided with a positioning pin 4 that can reciprocate in an arc shape. The rotating seat 3 is rotated until the limiting portion 3.1 cooperates with the positioning portion 2.1, and the position of the fitting groove 3.2 rotates with the rotating seat 3 to allow the positioning pin 4 to enter or move out;

[0037] The positioning pin 4 enters the fitting groove 3.2 to position the fixing seat circumferentially.

[0038] When the lifting shaft 2 is in the second position, it is disconnected from the cover body, and the rotating seat 3 can be rotated until the limiting part 3.1 cooperates with the positioning part 2.1, so as to prevent the lifting shaft 2 from moving and leaving this state, so that the device can operate reliably;

[0039] A positioning pin 4 that can move back and forth in an arc shape is provided. After the rotating seat 3 is rotated to the point where the limiting portion 3.1 cooperates with the positioning portion 2.1, the engaging groove 3.2 on the rotating seat 3 moves to a position where the positioning pin 4 can enter and exit. At this time, the positioning pin 4 moves in an arc shape into the engaging groove 3.2, which can limit the rotating seat 3 circumferentially to prevent the rotating seat 3 from rotating, so that the rotating seat 3 is stably in a state where the limiting portion 3.1 cooperates with the positioning portion 2.1. Therefore, the lifting shaft 2 can be stably in the second position state, and the operating reliability of the device is better.

[0040] As an improvement of the present invention, the fitting groove 3.2 is arranged on the peripheral side of the rotating seat 3, the positioning pin 4 is arranged above the fitting groove 3.2, and the rotating seat 3 can be rotated until the inlet and outlet of the fitting groove 3.2 are opposite to the positioning pin 4. After the above improvement, the structure layout is reasonable and the production is simple.

[0041] As an improvement of the utility model, a motor 5 is provided on the mounting base 1, and a gear 5.2 is rotatably connected to the mounting base 1, and the gear 5.2 is driven to rotate by the motor 5;

[0042] The positioning pin 4 is arranged on the gear 5.2. The gear 5.2 adopts an incomplete gear 5.2, on which the positioning pin 4 is arranged, and the incomplete gear 5.2 is rotatably connected with the mounting base 1 through a pin shaft. The output end of the motor 5 is provided with a coaxial output gear 5.2, and the output gear 5.2 is meshedly connected with the incomplete gear 5.1. When the lifting shaft 2 enters the second position state, the motor 5 obtains a driving signal, drives the output gear 5.1 to rotate, and then drives the incomplete gear 5.2 to rotate forward, so that the positioning pin 4 moves along the arc moving trajectory and enters the fitting groove 3.2, and the rotating seat 3 obtains circumferential limit;

[0043] If the lifting shaft 2 needs to rise, the motor 5 drives the output gear 5.25.1 to rotate, thereby driving the incomplete gear 5.2 to rotate in the opposite direction, so that the positioning pin 4 moves along the arc moving trajectory and moves out of the fitting groove 3.2, and the rotating seat 3 loses the circumferential limit.

[0044] The motor 5 is used to drive the arc movement of the positioning pin 4 through the gear 5.2 transmission mechanism, which has the characteristics of stable and reliable operation and high degree of automation.

[0045] As an improvement of the present utility model, the mounting base 1 is further provided with a guide shaft 6, and the guide shaft 6 penetrates into the inner hole of the lifting shaft 2;

[0046] A fitting block 6.1 is arranged on the outer side of the guide shaft 6, and an axially extending spiral groove is arranged on the inner hole wall of the lifting shaft 2, and the fitting block 6.1 is matched and connected with the spiral groove 2.2.

[0047] After the above improvement, the lifting shaft 2 is sleeved on the outside of the guide shaft 6, and after the fitting block 6.1 on the guide shaft 6 fits with the spiral groove 2.2 on the lifting shaft 2, the lifting shaft 2 can be guided to rotate circumferentially during the axial movement.

[0048] As an improvement of the present invention, an elastic member 7 is disposed between the lifting shaft 2 and the guide shaft 6. The elastic member 7 is a spring, one end of which is disposed in the inner hole of the guide shaft 6 and abuts against the guide shaft 6, and the other end of the spring is disposed in the inner hole of the lifting shaft 2 and abuts against the lifting shaft 2. The pre-tightening effect of the spring can drive the lifting shaft 2 to always have a tendency to move upward;

[0049] After the rotating seat 3 rotates circumferentially until the positioning portion 2.1 is disengaged from the limiting portion 3.1, the lifting shaft 2 can automatically rise and move to the first position state under the action of the spring.

[0050] As an improvement of the present utility model, the rotating seat 3 is sleeved on the outer side of the lifting shaft 2, and the positioning part 2.1 is a key body protruding from the outer wall of the lifting shaft 2;

[0051] A protrusion is provided in the inner hole of the rotating seat 3, and the limiting part 3.1 is a positioning groove arranged at the bottom of the protrusion. The side wall of the positioning groove is set low on the left and high on the right. The lifting shaft 2 descends to the height of the key body lower than the right side wall of the positioning groove. The rotating seat 3 rotates counterclockwise to make the key body enter the positioning groove to limit the rise of the lifting shaft 2.

[0052] After the key body is combined with the positioning groove, the upper end surface of the key body abuts against the wall surface of the positioning groove, which can limit the rise of the lifting shaft 2, and has the characteristics of stable and reliable cooperation.

[0053] As an improvement of the utility model, a first stopper 8 is provided on the right side of the protrusion, a second stopper 9 is provided on the left side of the protrusion, a vertical first transmission groove 8.1 is formed between the first stopper 8 and the protrusion, and a vertical second transmission groove 9.1 is formed between the second stopper 9 and the protrusion;

[0054] The rotating seat 3 is provided with a torsion spring, one end of the torsion spring is connected to the mounting base 1, and the other end is connected to the rotating seat 3;

[0055] When the lifting shaft 2 is in the first position, the key body is located above the protrusion, the lifting shaft 2 descends, and the spiral groove 2.2 cooperates with the fitting block 6.1 to drive the lifting shaft 2 to rotate clockwise, and the key body enters the lower right side wall of the positioning groove through the first transmission groove 8.1. When the key body passes through the first transmission groove 8.1, it drives the rotating seat 3 to rotate clockwise, and the torsion spring is pre-tightened. When the height of the key body is lower than the right side wall of the positioning groove, the torsion spring drives the rotating seat 3 to rotate counterclockwise, so that the left side wall of the positioning groove is against the key body. When the lifting shaft 2 obtains the second position, the lifting shaft 2 descends until the height of the key body is lower than the left side wall of the positioning groove, the torsion spring resets to the initial state and drives the rotating seat 3 to continue to rotate counterclockwise, so that the key body rotates to the second transmission groove 9.1, and the lifting shaft 2 can rise along the second transmission groove 9.1.

[0056] Working principle: The head of the lifting shaft 2 is provided with a lock buckle 2.3, and the cover body is provided with a notch of the same shape as the lock buckle 2.3. When the lifting shaft 2 is at a specific angle, the lock buckle 2.3 can fit into the notch and then pass through the notch;

[0057] When the cover is in the closed state, the lifting shaft 2 is in the first position state in the ascending stroke. At this time, the lock buckle 2.3 passes through the notch, and under the cooperation of the fitting block 6.1 and the spiral groove 2.2, the lifting shaft 2 is driven to rotate counterclockwise to a preset angle. The lock buckle 2.3 and the notch form a blocking effect to fix the cover. At this time, under the pre-tightening effect of the spring, the position of the lifting shaft 2 is stable, which can make the position of the cover stable.

[0058] If the cover needs to be opened, the user presses the side of the cover close to the lifting shaft 2. After the cover is pressed in, the lifting shaft 2 is forced to enter the downward movement, and under the cooperation of the fitting block 6.1 and the spiral groove 2.2, the lifting shaft 2 is driven to rotate clockwise to a preset angle. At this time, the lock buckle 2.3 can pass through the notch, and the lifting shaft 2 continues to move downward under the force, driving the rotating seat 3 to rotate clockwise. The torsion spring is pre-tightened. When the key body passes through the first transmission groove 8.1 and moves to the lower right side of the positioning groove, the rotating seat 3 rotates counterclockwise due to the action of the torsion spring, and the left side wall of the positioning groove is against the key body. The pre-tightening effect of the spring drives the key body and the positioning groove to maintain a stable and tight abutment. The lifting shaft 2 is restricted from rising and moving, and is stably in the second position. At this time, the lock buckle 2.3 is out of the blocking cooperation with the notch, and the user can open the cover;

[0059] During this process, the mating groove 3.2 on the rotating seat 3 rotates to be opposite to the positioning pin 4. Furthermore, the motor 5 can drive the incomplete gear 5.2 to rotate forwardly through the output gear 5.1, thereby causing the positioning pin 4 to move in an arc shape into the mating groove 3.2, so that the rotating seat 3 is limited circumferentially, and the rotating seat 3 is stably maintained in the state of limiting the lifting shaft 2.

[0060] If the cover needs to be closed, first, the motor 5 can drive the incomplete gear 5.2 to rotate in the opposite direction through the output gear 5.1, so that the positioning pin 4 moves in an arc shape to move out of the fitting groove 3.2. Further, the user closes the cover, and after the cover contacts the lock buckle 2.3, the lifting shaft 2 is forced to move downward. After the height of the key body is lower than the left side wall of the positioning groove, the torsion spring continues to drive the rotating seat 3 to rotate counterclockwise. The position of the positioning groove is not relative to the key body, and the rotating seat 3 rotates counterclockwise until the key body on the lifting shaft 2 is in the second transmission groove 9.1. At this time, the spring drives the lifting shaft 2 to enter the rising movement stroke until the lock buckle 2.3 passes through the slot and forms a blocking fit with the slot.

[0061] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
