All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

Referring to fig. 1, a fuel tank charging flap lock according to the present embodiment includes: push rod 17, electric lock pin 21, motor 23.

As shown in fig. 1, the push lever 17 includes a cylindrical body 11, a latch 13 at the top of the cylindrical body 11, and a first rotary guide 15 on the side of the cylindrical body 11. The cylindrical body 11 is movably inserted into the upper cover 45. So that the cylindrical body 11 can move axially within the upper cover 45. The first rotary guide 15 is, for example, a spiral groove, and the upper cover 45 is provided therein with a second rotary guide for guiding the spiral groove, the second rotary guide being, for example, a guide projection, one end of which is fixed in the upper cover 45 and the other end of which extends into the spiral groove. The spiral groove can move along the guide projection, so that the cylindrical body 11 can rotate during the process that the bolt 13 or the cylindrical body 11 moves along the axial direction, thereby forming the rotation of the bolt 13. Of course, the first rotary guide 15 may be a guide projection, and the second rotary guide may be a guide groove provided on the inner wall of the upper cover 45. As shown in fig. 4, the push rod 17 is provided with a lock pin notch 19. The locking pin notch 19 is located on the other side of the first rotary guide 15 so as not to affect the movement of the spiral groove.

The electric lock pin 21 is movably provided at one side of the push rod 17. As shown in fig. 1, the power lock pin 21 is located outside the push rod 17. Of course, the electric lock pin 21 is not limited to be located outside the push rod 17, and the electric lock pin 21 may be located inside the push rod 17, which is not limited to this application. Further, the moving direction of the push rod 17 is perpendicular to the moving direction of the electric lock pin 21. The electric lock pin 21 is used for extending into the lock pin bayonet 19 to limit the push rod 17. That is, when the power lock pin 21 is inserted into the lock pin notch 19, the power lock pin 21 is caught in the lock pin notch 19, so that the cylindrical body 11 cannot move in the axial direction, thereby achieving locking. Further, a clamping groove is arranged on the upper cover 45. The lock pin bayonet 19 can face the notch when the push rod 17 moves downward, so that the electric lock pin 21 can extend into the lock pin bayonet 19 through the notch.

In the present embodiment, the rotating shaft 25 of the motor 23 is in transmission connection with the electric lock pin 21. So that when the motor 23 is powered on, the rotation shaft 25 rotates to drive the electric lock pin 21 to move. Further, the rotation shaft 25 is used for driving the electric lock pin 21 to move away from the lock pin bayonet 19, for example, as shown in fig. 1, the rotation shaft 25 is used for driving the electric lock pin 21 to move leftwards. Thereby pulling the electric lock pin 21 out of the lock pin catching groove 19. When the electric lock pin 21 is pulled out from the lock pin bayonet 19, the push rod 17 is not restricted by the electric lock pin 21, so that the push rod 17 can move upward by the second spring 33, thereby unlocking. Specifically, the rotating shaft 25 is in transmission connection with the electric lock pin 21 through a screw 27. Of course, the threaded rod 27 can also be a worm. Further, a transmission seat 29 is connected to the screw 27, and the electric lock pin 21 is arranged on the transmission seat. The driving seat 29 is translated by the screw driving of the screw 27 to form a stable and uniform unlocking. The motor 23 is controlled to start and stop.

As shown in fig. 1, in one embodiment, a second spring 33 is provided below the pushing rod 17, and the second spring 33 can be compressed when the pushing rod 17 moves downward to drive the pushing rod 17 to move upward. Therefore, when the electric lock pin 21 is pulled out from the lock pin bayonet 19, the push rod 17 is not restricted by the electric lock pin 21, so that the push rod 17 can move upward under the action of the second spring 33, thereby realizing unlocking. Therefore, when the lock is unlocked, the lock can be unlocked only by pressing the electric unlocking key, so that the operation is simplified, and convenience is provided for a driver.

Further, a positioning block 35 is inserted into the cylindrical body 11. The second spring 33 is disposed at the bottom of the positioning block 35. The positioning block 35 is clamped in the cylindrical main body 11 by a clamp spring. As shown in fig. 1, the positioning block 35 includes a cylinder inserted into the cylindrical body 11 and a protrusion 37 protruding from the outer side of the cylinder. The projection 37 is located outside the cylindrical body 11 so that the projection 37 can abut against the detection switch 39.

As shown in fig. 1, the fuel tank charging flap lock according to the present embodiment further includes: a first spring 31. As shown in fig. 2, in one embodiment, a first spring 31 is disposed between the power lock pin 21 and the motor 23. That is, one end of the first spring 31 abuts against the motor 23, and the other end of the first spring 31 abuts against the electric lock pin 21. The first spring 31 is compressed when the electric lock pin 21 is driven by the rotating shaft 25, so that the electric lock pin 21 can move toward the push rod 17 and extend into the lock pin notch 19 under the elastic force of the first spring 31. That is, as shown in fig. 1, when the motor 23 is energized and the rotating shaft 25 rotates to move the electric lock pin 21 to the left, the first spring 31 is compressed. So that the elastic force of the first spring 31 can move the power locking pin 21 rightward so that the power locking pin 21 can be inserted into the locking pin notch 19. Further, as shown in fig. 1, when the motor 23 is energized and the rotating shaft 25 rotates, the rotating shaft 25 rotates the screw 27 in the first direction, so that the electric lock pin 21 moves leftward. When the first spring 31 is compressed, the elastic force of the first spring 31 can make the electric lock pin 21 move rightwards, so that the electric lock pin 21 drives the screw 27 to rotate in the second direction, and the screw 27 drives the rotating shaft 25 to rotate in the second direction. And the first direction is opposite to the second direction. That is, when the screw 27 is rotated in the first direction, the motor 23 is energized. When the screw 27 is rotated in the second direction, the motor 23 is not energized. Thereby reducing the number of steps of operation.

As shown in fig. 1, in one embodiment, a detection switch 39 is electrically connected to the motor 23. The push rod 17 is provided with a protrusion 37, and when the protrusion 37 abuts against a detection switch 39, the detection switch 39 can generate an unlocking signal. Therefore, whether the oil tank opening cover is opened or not can be known according to the unlocking signal. And when the protrusion 37 is located below the detection switch 39, the detection switch 39 can generate a lock-off signal, so that whether the fuel tank opening cover is closed or not can be known according to the lock-off signal. So can accurately master the opening condition of the oil tank opening cover and be favorable for stroke safety.

Specifically, the detection switch 39 has a movable contact 43 and a fixed contact 41. When the movable contact 43 is electrically connected with the fixed contact 41, the detection switch 39 can generate an unlocking signal; the detection switch 39 can generate a lock-off signal when the movable contact 43 is disconnected from the fixed contact 41. That is, as shown in fig. 2, one side of the movable contact 43 can abut against the protrusion 37 after the pushing rod 17 moves upward, so that the other side of the movable contact 43 can be electrically connected to the fixed contact 41 to generate the unlocking signal. And as shown in fig. 2, one side of the movable contact 43 can be disengaged from the protrusion 37 after the push rod 17 is moved downward so that the other side of the movable contact 43 can be disconnected from the fixed contact 41 to generate a locking signal.

As shown in fig. 2 and 3, a projection 37 is provided on the bottom of the push rod 17. Specifically, the protrusion 37 is disposed on the positioning block 35. The detection switch 39 includes a housing on the side of the push rod 17, a fixed contact 41 disposed on the side of the housing facing the protrusion 37, and a movable contact 43 disposed between the fixed contact 41 and the protrusion 37. So that the movable contact 43 can abut against the projection 37 to be electrically connected with the fixed contact 41 when the pushing rod 17 is moved upward. When the pushing rod 17 moves downward, the movable contact 43 can be disengaged from the projection 37 to be disconnected from the fixed contact 41.

Further, the detection switch 39 is electrically connected to the controller. The controller is located in the cab. And the control is used for receiving an unlocking signal and a locking signal so that a driver can accurately master the opening condition of the oil tank opening cover through the unlocking signal and the locking signal, thereby being beneficial to stroke safety. Preferably, the detection switch 39 is a microswitch.

As shown in fig. 1, the fuel tank charging flap lock according to the present embodiment further includes: an upper cover 45 and a lower cover 47 which are buckled with each other. The cylindrical body 11 is inserted into the upper cover 45. One end of the second spring 33 abuts against the positioning block 35, and the other end of the second spring 33 abuts against the lower cover 47. The upper cover 45 and the lower cover 47 form a closed space in which the push rod 17, the electric lock pin 21, the first spring 31, the second spring 33, the motor 23, and the detection switch 39 are installed. The closed space can play the roles of closing and protecting.

The application discloses operation process of oil tank charging flap lock as follows:

when the lock is closed, the tank cap is manually closed so that the tank cap moves downward against the push rod 17 while compressing the second spring 33. When the lock pin bayonet 19 on the push rod 17 moves to be opposite to the electric lock pin 21, the electric lock pin 21 extends into the lock pin bayonet 19 under the action of the elastic force of the first spring 31, so that the push rod 17 cannot move, and the oil tank opening cover is closed. And in this process, the side of the push rod 17 has a first rotary guide 15, by which first rotary guide 15 the cylindrical body 11 is rotated, and the latch 13 is rotated during the pressing down to close the lock. At the same time, the projection 37 on the pushing rod 17 moves downward below the detection switch 39, and the detection switch 39 generates a lock-off signal.

When the lock is unlocked, the electric unlocking key is pressed, the rotating shaft 25 of the motor 23 rotates, and the rotating shaft 25 drives the screw 27 to rotate, so that the electric lock pin 21 is withdrawn from the lock pin bayonet 19. Since the push rod 17 is not restricted by the electric lock pin 21, the push rod 17 can move upward by the second spring 33, and unlocking is performed. And in this process, the side of the push rod 17 has a first rotary guide 15, by which first rotary guide 15 the cylindrical body 11 is rotated, and the latch 13 is rotated during the pressing down to unlock the lock. At the same time, the projection 37 of the pressing rod 17 moves upward to abut against the detection switch 39, and the detection switch 39 generates an unlocking signal.

It can be seen from the above scheme that when the oil tank charging port cover lock of the embodiment of the present application is locked by setting the pushing rod 17, the electric lock pin 21, the motor 23 and the first spring 31, the oil tank port cover only needs to be manually closed, and the electric lock pin 21 can be enabled to extend into the lock pin bayonet 19 under the action of the first spring 31. Without the need for operation of the power button. Therefore, the operation of the oil tank charging cover lock is simple and convenient, and convenience is provided for a driver.
