DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] like Figure 1 As shown, the electric gun line management device 30 of the utility model embodiment includes: a driving reel 31, a suspension rope 32, a motor 33 and a locking structure 34, wherein a clamp 35 is provided at one end of the suspension rope 32, and the clamp 35 is used to connect the gun line 20 with the suspension rope 32, and the other end of the suspension rope 32 is wound around the driving reel 31; the motor 33 is mechanically connected to the driving reel 31, and the motor 33 is used to drive the driving reel 31 to rotate counterclockwise or clockwise to realize the release and recovery of the suspension rope 32, wherein the electric gun line management device 20 with the suspension rope 32 in the released state is as shown in FIG. Figure 2 As shown; the locking structure 34 includes an intermittent transmission wheel 341, a control rod 342 and a reset spring 343. The intermittent transmission wheel 341 is fixedly arranged on the driving reel 31 and rotates synchronously with the driving reel 31. A rack 3411 is arranged on one side of the intermittent transmission wheel 341, and the other side of the intermittent transmission wheel 341 is a smooth curved surface 3412. One end of the control rod 342 can engage with the rack 3411 of the intermittent transmission wheel 341 when the intermittent transmission wheel 341 rotates, and the other end of the control rod 342 is connected to the reset spring 343. The reset spring 343 is used to reset the control rod 342 to a natural state.
[0024] It is understandable that the motor 33 in this embodiment can be a servo motor, a stepper motor or other types of motors, and this embodiment is not limited. The clamp 35 can be an elastic clamp, the size of which matches the diameter of the gun line 20, and the clamp 35 can also be a set of buckles, the diameter of the through hole between the buckles matches the diameter of the gun line 20, etc., and this embodiment is not limited. The suspension rope 32 can be a steel wire rope, a nylon rope, a PE rope or a suspension rope made of other materials, and this embodiment is not limited.
[0025] like Figure 3 As shown, when charging is required, the operator pulls the gun line 20 or the charging gun 10 at the end of the gun line 20, so that the clamp 35 on the gun line 20 drives the rope 32, and then drives the driving reel 31. At this time, the motor 33 mechanically connected to the driving reel 31 is also driven to rotate (state 1, 2), so that the motor 33 rotates autonomously to release the rope 32 (state 2, 3); when the rope 32 is released to a certain length, the motor 33 stops rotating, the driving reel 31 stops rotating, and one end of the brake rod 342 stops rotating. At the meshing point with the rack 3411 of the intermittent transmission wheel 341, the intermittent transmission wheel 341 cooperates with the braking rod 342 to stop (states 4 and 5), so that the lifting rope 32 stops being released. At this time, the operator can easily pick up the charging gun 10 for charging. Among them, when the electric gun line management device 30 is in state 1, the locking structure 34 is in an unlocked state (that is, the braking rod 342 is not meshed with the rack 3411 of the intermittent transmission wheel 341), so the operator can easily pull the gun line 20 to drive the motor 33.
[0026] When charging is finished, the operator pulls the gun line 20 or the charging gun 10 at the end of the gun line 20 again, so that the hoop 35 on the gun line 20 drives the sling 32, and then drives the driving reel 31. At this time, the motor 33 mechanically connected to the driving reel 31 is also driven to rotate (states 6 and 7). The encoder set in the motor 33 receives the rotation displacement signal of the motor shaft, and the motor 33 starts to act, so that the driving reel 31 drives the intermittent transmission wheel 341 to rotate, and the pawl 342 is disengaged from the rack 3411 of the intermittent transmission wheel 341, and the locking structure 34 is unlocked (states 7 and 8); then the motor 33 rotates in the opposite direction to recover the sling 32, and the sling 32 drives the clamp 35, thereby realizing the recovery of the gun line 20 (states 9, 10, 11), until the sling 32 returns to the initial position (as shown in state 12, at this time the locking structure 34 is in the unlocked state, and the braking rod 342 is not engaged with the rack 3411 of the intermittent transmission wheel 341), wherein, when one end of the braking rod 342 moves from the meshing position of the rack 3411 of the intermittent transmission wheel 341 to the smooth curved surface 3412 of the intermittent transmission wheel 341, the braking rod 342 can be reset to the natural state (as shown in states 8 and 12) by the restoring force of the reset spring 343.
[0027] Since a locking structure 34 is provided in the electric gun line management device 30, even if the electric gun line management device 30 is overloaded with tension, the motor shaft of the motor 33 will not be pulled and rotated because the locking engagement of the intermittent transmission wheel 341 and the braking rod 342 can withstand a very large pulling force, thereby well protecting the motor 33 and the entire electric gun line management device 30.
[0028] It should be noted that there may be a variety of situations that cause the electric gun line management device 30 to be subjected to overload tension, including but not limited to: during the rotation of the motor 33 before charging, the operator uses too much pulling force or the operator's action is improper (the body is tilted to pull, and the operator's own weight is added to the pulling force); during the charging process, the car slips (uneven ground, handbrake not pulled, etc.); during the charging process, someone or something passes by and trips over the gun line 20 or the rope 32 and continues to move, and the rope 32 will be subjected to a relatively large pulling force; after charging, the driver forgets to pull out the charging gun 10 and directly starts the car to move.
[0029] The electric gun line management device 30 of this embodiment is provided with a motor 33 to retract and release the sling 32 to drive the gun line 20 to unfold and retract it, which can effectively increase the effective charging distance of the gun line 20 and realize automatic resetting of the sling 32; the operator does not need to spend a lot of effort to pull the gun line 20 all the time, which is more labor-saving and has a good experience; by providing an intermittent transmission wheel 341 and a braking rod 342 to withstand a large pulling force, the motor 33 and the entire electric gun line management device 30 can be protected when there is an overload tension in the electric gun line management device 30.
[0030] like Figure 1 As shown, in one embodiment of the present invention, the electric gun line management device 30 may further include a housing 36 for fixing the electric gun line management device 30 on the charging pile, and the detent rod shaft of the detent rod 342 is fixedly arranged on the inner surface of the housing 36, and a rib plate is arranged on the inner surface of the housing 36 for limiting the reset spring 343. Figure 3 In the embodiment, the clamp 35 can extend from the lower side of the shell to drive the gun line 20 to move. When the suspension rope 32 is in the initial position, the shell 36 can cover all structures in the electric gun line management device 30 except the clamp 35 to prevent rain from corroding other structures in the electric gun line management device 30.
[0031] Understandably, Figure 1This is only one way of setting the shell 36. The specific shape and setting method of the shell 36 are not limited here. In other specific embodiments, it can be changed according to user needs. For example, the shell 36 is an open shell, and the rear side of the shell 36 is fixed on the charging pile. The front baffle of the shell 36 is fixed with a control rod shaft and a rib plate for limiting the reset spring 343. No baffles are set on the left and right sides of the shell 36, which is convenient for directly observing the working status of the electric gun line management device 30, etc. This embodiment does not limit it.
[0032] like Figure 1 As shown, in one embodiment of the present utility model, a reducer 37 is provided between the motor 33 and the driving reel 31 , the motor 33 is key-connected to the reducer 37 , and the reducer 37 is key-connected to the driving reel 31 .
[0033] It should be noted that since the rated speed of the motor 33 is generally in the range of 1500 to 2500 RPM, the speed is too fast, so it is necessary to add a reducer 37 between the drive reel 31 and the motor 33 to reduce the speed of the drive reel 31 that rotates along with it; at the same time, the reducer 37 can amplify the torque of the motor 33 to achieve high torque output and increase the lifting force of the entire electric gun line management device 30.
[0034] It is understandable that the reducer 37 in this embodiment can be a planetary reducer, a worm gear or other types of reducers, and this embodiment is not limited. In other specific embodiments, other mechanical transmission connection methods can be used to connect the motor 33 and the reducer 37, and the reducer 37 and the drive reel 31 according to actual needs, such as a coupling connection, etc., and this embodiment is not limited.
[0035] In one embodiment of the utility model, the electric gun line management device 30 may also include a driver, which is used to detect the torque of the motor 33. Specifically, the driver can automatically convert the current and voltage of the motor 33 into a torque value. When the gun line 20 is suddenly pulled by a large force, the motor shaft of the motor 33 will be subjected to a large instantaneous rotational force. At this time, the driver detects the impact current generated in the motor 33 and automatically converts it into a torque value. By judging whether the torque value of the motor 33 exceeds the preset standard value, it is determined whether the motor 33 is subjected to an overload tension. If the torque value of the motor 33 exceeds the preset standard value, the motor 33 will automatically brake and stop running to achieve the function of over-tension protection and ensure safety in use.
[0036] In one embodiment of the utility model, an encoder is provided in the motor 33, and the encoder is used to detect the rotation displacement signal of the motor shaft of the motor 33. When the encoder detects that the motor shaft of the motor 33 is rotated and generates an angular displacement signal, the motor 33 will rotate a preset number of times to increase the length of the suspension rope 32 outside the driving reel 31 and expand the movable range of the gun line 20, wherein the preset number of times can be set by a software program according to actual needs.
[0037] In one embodiment of the utility model, several automatic stop points can be set in the process of releasing the suspension rope 32, and the preset number of revolutions of the motor 33 is determined according to the distance between each two adjacent automatic stop points to meet the charging of cars parked at different positions. If the operator pulls the gun line 20 at a certain automatic stop point, and the charging gun 10 still cannot charge the car, the operator can continue to pull the gun line 20, and the encoder in the motor 33 detects that the motor shaft is rotated and generates an angular displacement signal, and the motor 33 will rotate the preset number of revolutions to the next automatic stop point to meet the charging function at a longer distance.
[0038] like Figure 1 As shown, in one embodiment of the present invention, the electric gun line management device 30 further includes: a power line 38, which is connected to the motor 33 and is used to enable the motor 33 to obtain external power supply. The external power supply can be direct current or alternating current, and the specific method can be determined according to the type of the motor 33.
[0039] like Figure 1 As shown, in one embodiment of the present utility model, the electric gun line management device 30 also includes: a signal line 39, the signal line 39 is connected to the motor 33, and the motor 33 communicates with the charging pile through the signal line 39.
[0040] Specifically, the motor 33 can realize bus communication with the charging pile through the signal line 39, such as RS485 communication, and a touch screen can be installed on the charging pile. By changing the configuration parameters in the program, the electric gun line management device 30 can realize some automatic control functions, such as adjusting the fixed length release and recovery of the sling 32, the segmented control of the length of the release and recovery of the sling 32, and the segmented setting of the retraction speed.
[0041] According to the electric gun line management device of the embodiment of the utility model, by arranging a motor to retract and release the sling to drive the gun line to unfold and retract it, the effective distance over which the gun line can be charged can be effectively increased, and the automatic resetting of the sling can be achieved; the operator does not need to expend great effort to pull the gun line all the time, which is more labor-saving and has a good experience; by arranging the intermittent transmission wheel and the braking rod to withstand a large pulling force, the motor and the entire electric gun line management device can be protected when there is an overload pulling force in the electric gun line management device.
[0042] Based on the electric gun line management device of the above embodiment, the utility model also provides a charging pile.
[0043] like Figure 1 As shown, the charging pile of the embodiment of the utility model includes a charging gun 10, a gun line 20 and an electric gun line management device 30 of any of the above embodiments of the utility model.
