Example 1
Referring to fig. 1 to 3, the electronic lock device of the charging gun of the present embodiment includes a housing 1, and a driving member 2 and a plunger 3 disposed in the housing 1. Specifically, optionally, the housing 1 includes an upper housing 101 and a lower housing 102 that can be fastened to each other, a cavity that can accommodate the driving member 2 and each component is provided in the lower housing 102, the driving member 2 and the ejector rod 3 are both provided in the lower housing 102, and the upper housing 101 is covered on the lower housing 102 through screw locking.
One end of the top rod 3 is located in the housing 1 and is in transmission connection with the driving part 2, while the other end is a main rod 30, and the main rod 30 penetrates through one end face of the lower housing 102. Under the drive of the driving part 2, the main rod body 30 of the mandril 3 can be pushed out or retracted. During operation, the main rod 30 of the push rod 3 is driven by the driver 2 to be pushed out for locking or retracted for unlocking.
In a specific embodiment, the driving member 2 is a servo motor, and can be servo-controlled by a control system, so that the locking and unlocking of the charging gun electronic lock device can be electromechanically controlled, and the locking and unlocking speed and state can be stably controlled.
Specifically, one end of the ejector rod 3, which is positioned in the shell 1, is in transmission connection with the driving piece 2 through the driving wheel 4.
As shown in fig. 4, the drive pulley 4 has an engaging portion 41, and an extending rod portion 42 that projects downward in the axial direction of the engaging portion 41. The engaging portion 41 of the driving wheel 4 is engaged and driven with the driving member 2, and the extending rod portion 42 has teeth 420. Meanwhile, as shown in fig. 5, a transmission notch 31 is formed in one end of the top rod 3 located in the housing 1, and an end surface where the tooth 420 is located in the transmission notch 31. And the edge of the transmission notch 31 is provided with a tooth socket 310 correspondingly matched with the tooth 420, the tooth on the front side of the tooth socket 310 along the push-out direction of the push rod 3 protrudes towards the middle position of the transmission notch 31, and the tooth 420 is meshed with the tooth socket 310. Thus, under the driving of the driving element 2, the driving element 2 is engaged with the engaging portion 41 of the driving wheel 4 to drive the extending rod portion 42 to rotate, and drives the teeth 420 on the extending rod portion 42 to rotate, and the teeth 420 are in transmission fit with the tooth socket 310, so as to drive the main rod 30 of the push rod 3 to be pushed out or retracted.
Referring to fig. 4 again, the transmission notch 31 is an irregular circular groove, and includes a large circular groove at the front end in the pushing direction of the push rod 3 and a small circular groove at the rear end in the pushing direction of the push rod 3, the large circular groove and the small circular groove are communicated with each other and partially overlapped, the tooth socket 310 is located in the large circular groove and at the critical position of the large circular groove and the small circular groove, the tooth 420 and the inner wall of the large circular groove outside the tooth socket 310 are always in interference fit, and the tooth 420 rotates in the large circular groove for one circle and slides into the tooth socket 310. When the teeth 420 are matched with the tooth grooves 310 to push the push rod 3 out of position, the tops of the teeth 420 and the teeth of the tooth grooves 310 on the front side in the push-out direction of the push rod 3 are still tightly pressed against each other, and the extension rod part 42 is located in the small circular groove at this time, so that the teeth 420 rotate in the direction of pushing the push rod 3 under the action of pushing the teeth 420 out of position without external force before and after the push rod 3 is pushed out of position due to the limitation of the teeth of the tooth grooves 310 on the front side in the push-out direction of the push rod 3, and the teeth 420 cannot be separated from the tooth grooves 310. Similarly, when the teeth 420 cooperate with the tooth grooves 310 to draw and retract the push rod 3 to a proper position, the top of the teeth 420 and the teeth on the rear side of the tooth grooves 310 in the pushing direction of the push rod 3 are still tightly pressed against each other, and the extension rod portion 42 is located in the large circular groove, even if the teeth 420 are still located in the tooth grooves 310 before and when the push rod 3 retracts to a proper position. Thus, the teeth 420 and the tooth sockets 310 are always kept in a stable meshing transmission fit relation in the normal locking and unlocking process.
In addition, optionally, the meshing part 41 of the driving wheel 4 is in meshing transmission connection with the driving piece 2 through the gear set 6 and the worm 7. The gear set 6 comprises a motor gear 61 arranged at the output end of the driving piece 2 and used for being in meshing transmission with a gear on the worm 7, and a secondary bevel lever gear 62 arranged between the worm 7 and the driving wheel 4 and used for being in meshing transmission with the worm 7 and the driving wheel 4. Furthermore, the worm 7 is arranged axially parallel to the output of the driver 2 to save space. Therefore, through the transmission connection of the gear set 6 and the worm 7, the output torque of the driving piece 2 to the driving wheel 4 can be effectively improved, and finally the pushing and traction torque of the ejector rod 3 is improved.
The charging gun electronic lock device of the embodiment is further provided with a manual reset system for conveniently and quickly manually unlocking the device when electromechanical and other faults occur after the device is locked. Wherein the manual reset system comprises a reset rocker arm 5 arranged outside the housing 1. After the ejector rod 3 is pushed out, the reset rocker arm 5 is toggled to drive the ejector rod 3 to be separated from the driving wheel 4 in a transmission way and retract for resetting. Specifically, after the push rod 3 is pushed out, the reset rocker arm 5 is pushed by an external force to drive the teeth 420 to be separated from the tooth grooves 310, so that the push rod 3 and the driving wheel 4 are separated in a transmission manner, and then the push rod 3 is driven to retract and reset.
Furthermore, the reset rocker arm 5 is arranged outside the shell 1, and the manual reset system further comprises a reset deflector rod 8 arranged in the shell 1, wherein the axial direction of a rod body of the reset deflector rod 8 is perpendicular to the telescopic direction of the ejector rod 3, and the reset deflector rod 8 is fixedly connected with the reset rocker arm 5 and can be driven to rotate by the reset rocker arm 5. Referring to fig. 6, the reset lever 8 has a driving wheel contact arm 81 and a push rod contact arm 82 which are integrated, the driving wheel contact arm 81 and the push rod contact arm 82 are both perpendicular to the shaft of the reset lever 8, and the driving wheel contact arm 81 and the push rod contact arm 82 are disposed opposite to each other. Correspondingly, the driving wheel contact arm 81 is correspondingly positioned in the circular axial range of the meshing part 41 of the driving wheel 4, when the reset rocker arm 5 is shifted to drive the reset shifting lever 8 to rotate, the driving wheel contact arm 81 and the meshing part 41 of the driving wheel 4 interfere with each other in the direction rotating along with the rod body of the reset shifting lever 8, and can jack up the driving wheel 4; and the push rod 3 is provided with a reset step 32 corresponding to the push rod contact arm 82, when the reset rocker arm 5 is toggled to drive the reset shift lever 8 to rotate, after the drive wheel contact arm 81 jacks up the drive wheel 4, the reset rocker arm 5 drives to drive the continuous reset shift lever 8 to rotate, and the push rod contact arm 82 interferes with the reset step 32 in the direction rotating along with the rod body of the reset shift lever 8 and drives the push rod 3 to retract and reset.
Therefore, after the ejector rod 3 is pushed out, the reset rocker arm 5 is pushed to drive the reset deflector rod 8 to rotate. When the reset shift lever 8 is driven by the reset rocker arm 5 to rotate, the push rod contact arm 82 and the driving wheel contact arm 81 rotate along with the reset shift lever 8, so that the driving wheel contact arm 81 is in contact with the driving wheel 4 and jacks up the driving wheel 4 to separate the teeth 420 from the tooth grooves 310, the reset rocker arm 5 drives the continuous reset shift lever 8 to rotate, and the push rod contact arm 82 is in contact with the push rod 3 and drives the push rod 3 to retract and reset. After the teeth 420 are separated from the tooth grooves 310 and the ejector rod 3 retracts and returns to the initial closed position, the teeth 420 are located above the axial direction of the transmission notch 31, the end face where the teeth 420 are located is reset to be located in the transmission notch 31, and after the device fault is relieved, the driving piece 2 continues to drive the teeth 420 to rotate around the transmission notch 31, so that the teeth 420 can return to the initial position meshed with the tooth grooves 310, and the electronic lock device can continue to perform normal electromechanical driving and locking operation.
In the manual reset process, as shown in fig. 7 and 8, the tooth socket 310 on the ejector rod 3 and the tooth 420 on the driving wheel 4 are in a transmission separation state, so that the ejector rod 3 does not have a transmission effect with the driving wheel 4 in the retraction reset process, the retraction reset moving process of the ejector rod 3 does not need to drive the driving wheel 4, the gear set 6 and the driving part 2 to rotate, that is, the reverse thrust caused by the driving wheel 4, the gear set 6 and the driving part 2 does not need to be overcome, the reset work is smaller, especially when a device failure fault caused by the jamming of a gear or the driving part occurs, the reset is still easy and reliable, the reset convenience of the ejector rod 3 is improved, and the damage to internal parts of the device can be effectively reduced.
In this embodiment, it is preferable that each of the driving wheel contact arm 81 and the push rod contact arm 82 includes two arms symmetrically arranged along the center of the driving wheel 4. Correspondingly, the left side and the right side of the mandril 3 are provided with reset steps 32 corresponding to the mandril contact arms 82. The driving wheel contact arm 81 and the ejector rod contact arm 82 are symmetrically arranged, so that the stress of the driving wheel 4 which is jacked up and the stress of the ejector rod 3 which is pushed and retracted are more balanced, and the manual reset process is kept more stable.
Referring to fig. 9, a reset torsion spring 9 is sleeved on the reset deflector rod 8, wherein two ends of the reset torsion spring 9 are respectively connected to and act on the housing 1 and the reset deflector rod 8. When the reset rocker arm 5 drives the reset deflector rod 8 to rotate so as to enable the ejector rod 3 to retract and reset, the reset torsion spring 9 is compressed, and when the ejector rod 3 retracts and resets in place and external force applied to the reset rocker arm 5 is removed, elastic potential energy accumulated by the reset torsion spring 9 drives the reset deflector rod 8 to reversely rotate and simultaneously drives the reset rocker arm 5 to reversely rotate, so that the reset deflector rod 8 and the reset rocker arm 5 automatically return to the initial position for next manual reset.
And a return spring 10 is arranged between the top of the driving wheel 4 and the shell 1. Wherein, one end of the return spring 10 is connected to act on the shell 1, and the other end is connected to act on the top of the driving wheel 4. In the process that the reset deflector rod 8 rotates and drives the driving wheel contact arm 81 to contact with the driving wheel 4 and jack up the driving wheel 4, the reset spring 10 is compressed, when the ejector rod 3 retracts to reset to the right position and removes the external force applied to the reset rocker arm 5, and the reset deflector rod 8 resets under the drive of the reset torsion spring 9, the elastic potential energy accumulated by the reset spring 10 drives the driving wheel 4 to descend, so that the end surface where the tooth 420 is located automatically resets to be located in the transmission notch 31, and the continuous meshing transmission of the tooth 420 and the tooth socket 310 after the ejector rod 3 resets is ensured.
Referring to fig. 10a to 10d, a manual reset system composed of the reset rocker arm 5, the reset shift lever 8, the reset torsion spring 9 and the reset spring 10 performs manual reset of the push rod 3 (an arrow in the figure indicates a moving direction of the reset rocker arm 5, an upper view in the figure is a side view of a manual reset working state, and a lower view in the figure is a corresponding bottom view), when the push rod 3 needs to be manually reset after being pushed out, the reset rocker arm 5 is shifted to drive the reset shift lever 8 to rotate, a push rod contact arm 82 on the reset shift lever 8 and a driving wheel contact arm 81 work, and the driving wheel 4 is sequentially jacked up and the push rod 3 is sequentially and respectively retracted to reset. After the mandril 3 retracts and resets to the right position, the reset deflector rod 8 and the reset rocker arm 5 are driven by the reset torsion spring 9 to rotate reversely and return to the original position; and the return spring 10 drives the driving wheel 4 to descend, so that the end surface where the teeth 420 are located automatically returns to be located in the transmission notch 31.
In addition, in the electronic lock device of the charging gun, a detection switch 11 is also arranged in the shell 1, and the detection switch 11 can detect the push-out and retraction in-place conditions of the push rod 3. And the detection switch 11 is servo-connected with the driving part 2 through the controller, and after the detection switch 11 detects the push-out or retraction of the ejector rod 3 to the right position, a feedback signal is sent to the controller, and the controller sends an instruction to control the operation of the driving part 2, so that the electromechanical feedback control of locking and unlocking of the charging gun electronic lock device is realized.
Specifically, a closed switch step 33 and an open switch groove 34 are sequentially arranged on one end of the ejector rod 3 in the shell 1 along the pushing direction of the ejector rod 3. As shown in fig. 11 and 12, when the main rod 30 of the push rod 3 is pushed out to the proper position, the closing switch step 33 will abut against the detection switch 11 correspondingly, so as to close the detection switch 11, and the detection switch 11 will send out a closing signal; when the main rod 30 of the push rod 3 retracts to the position, the opening switch groove 34 corresponds to the detection switch 11 and is separated from the detection switch 11, the detection switch 11 is opened, and the detection switch 11 sends an opening signal. And the controller servo-connected with the detection switch 11 and the driving member 2 can control the on-off of the circuit of the driving member 2 according to the closing or opening signal of the detection switch 11, so as to control the operation of the driving member 2, and realize the accurate locking and unlocking control of the charging gun electronic lock device.
Example 2
The difference of the charge gun electronic lock device of the present embodiment from embodiment 1 is that, as shown in fig. 13 to 15, a first open switch recess 341, a closed switch step 33, and a second open switch recess 342 are provided in this order on one end of the jack 3 located inside the housing 1 in the pushing direction of the jack 3.
When the main rod 30 of the top rod 3 retracts to the right position, the first open switch groove 341 corresponds to the detection switch 11 and is separated from the detection switch 11, and at this time, the detection switch 11 is opened; similarly, when the main rod 30 of the push rod 3 is pushed out to the right position, the second opening switch groove 342 corresponds to the detection switch 11 and is separated from the detection switch 11, and at this time, the detection switch 11 is also in an opening state. In the middle of the pushing out or retracting process of the main rod 30 of the push rod 3, the closing switch step 33 will pass back through the detection switch 11 and abut against the detection switch 11, so that the detection switch 11 is closed.
Therefore, the pushing-out in-place and the retracting in-place of the main rod body 30 of the ejector rod 3 are judged to be in place through an opening switch signal sent by the detection switch 11, moreover, one end of the ejector rod 3 located in the shell 1 is only contacted with the detection switch 11 in the middle process of pushing-out and retracting, and after the pushing-out or retracting in-place of the ejector rod 3, one end of the ejector rod 3 located in the shell 1 is not contacted with the detection switch 11. Therefore, the ejector rod 3 is not required to be abutted with the detection switch 11 to be judged in place, namely, the locked rotor of the driving piece 2 is not required to be judged in place, and the service life of the driving piece 2 is prolonged.
