Description

Technical Field

[0001] The present invention relates to the technical field of charging equipment, and in particular to an automatic gun-releasing traction mechanism and a charging device. Background Art

[0002] With the policy advocacy of energy conservation and emission reduction, more and more countries have developed new energy markets, among which charging pile charging technology is one of the necessary technologies for the development of new energy.

[0003] In related technologies, charging equipment usually includes a charging pile, a charging cable, and a charging gun head. In actual use, the user needs to go to the charging pile to remove the charging gun head, then hold the charging gun head close to the charging port of the new energy vehicle model, and then insert the charging gun head into the charging port.

[0004] However, during each charging operation, the user also needs to completely brake the new energy vehicle, park it near the charging pile, and then get off the vehicle to pick up the charging gun head. Since the charging gun head is still connected to the charging cable, the user also needs to manually adjust and pull the charging cable during the process of picking up and storing the charging gun head to finally complete the entire charging operation. If the charging peak period is encountered, each charging operation requires a certain amount of charging time. During the long queue waiting for charging, the time for picking up and storing the charging gun during the entire charging operation is particularly time-consuming, and there is room for improvement. Summary of the Invention

[0005] In order to make charging operations more convenient, the present application provides an automatic gun-releasing traction mechanism.

[0006] The present application provides an automatic gun release traction mechanism that adopts the following technical solutions:

[0007] An automatic gun removal traction mechanism includes a frame, a fixing assembly for fixing a charging gun head is provided on the frame, and a moving assembly for moving the fixing assembly to a position close to a charging port is provided on the frame;

[0008] It also includes a reverse push and release assembly provided on the charging gun and configured to release the charging gun head from the charging port by reverse push acting on the periphery of the charging port;

[0009] It also includes a cable reeling assembly arranged on the frame for reeling the cable. After reeling, the charging gun is reconnected to the moving assembly.

[0010] By adopting the above technical solution, in actual use, the charging gun head is pre-fixed by using the fixed component, and combined with the automatic movement of the mobile component, after the vehicle parking action is completed, the mobile component can drive the fixed component of the fixed charging gun to move the charging gun head to a position close to the vehicle charging port. The operator only needs to walk straight to the position of the vehicle charging port after getting off the vehicle, and then take the charging gun head and complete the action of inserting the charging gun head. After the charging operation is completed, the reverse push disengagement component is used to disengage the charging gun from the charging port, and then the mobile component is used to reset the charging gun to its original position. That is, the operator does not need to manually operate the gun disengagement operation. At this time, the operator can wait in the car, eliminating the entire process of manually disengaging the gun and manually moving the charging gun, greatly improving the efficiency of each charging, and making the entire charging operation more convenient.

[0011] Preferably, it further comprises a cable traveling assembly arranged on the charging gun cable, the fixing assembly is arranged on the cable traveling assembly, and the reverse push-off assembly is arranged on the fixing assembly.

[0012] When charging is completed and the gun is to be removed, the cable traveling assembly moves the fixing assembly and the reverse push and detachment assembly along the charging gun cable to the tail end of the charging gun. At this time, the fixing assembly clamps and fixes the charging gun, and then the reverse push and detachment assembly detaches the charging gun from the charging port under the action of the fixing assembly. After that, the cable winding assembly retracts the cable to the fixing assembly and connects it to the moving assembly.

[0013] By adopting the above technical solution, in actual use, after charging is completed, the cable walking assembly will walk along the cable of the charging gun to the tail end of the charging gun head. When it contacts the tail end of the charging gun, the fixed assembly on the walking assembly will clamp and fix the charging gun. Then, the reverse thrust detachment assembly applies a reverse thrust on the side of the charging port on its fixed basis, thereby realizing automatic detachment of the charging gun from the charging port. Since the position of the fixed assembly is close to the charging port, the detached charging gun will be suspended in the air. At this time, the cable winding assembly will rewind the cable and recycle it to the cable walking assembly and reconnect it to the moving assembly to ensure the later transfer operation of the charging gun head, that is, the cable walking assembly and the cable winding assembly are used to realize the gun detachment operation suitable for different models of charging gun heads.

[0014] Preferably, the reverse thrust disengagement assembly is detachably fixed on the charging gun.

[0015] By adopting the above technical solution, the reverse push separation component is detachably fixed on the charging gun, which is equivalent to a non-standard modification of the charging gun. At this time, after charging is completed, the reverse push separation component uses the reverse push principle to apply a reverse thrust to the position near the charging port, thereby separating the charging gun from the charging port. After the separation is completed, the cable reeling component reels the cable until the charging gun is recovered and connected to the moving component to ensure that the next charging gun transfer operation is carried out normally.

[0016] Preferably, the reverse thrust disengagement assembly includes a reverse thrust rod that is telescopically arranged and a first driving member for driving the reverse thrust rod to telescopically move, and the reverse thrust rod acts on a fixed position on the peripheral side of the charging port, and the stroke of the reverse thrust rod after abutting against the fixed position is greater than the insertion stroke of the charging gun.

[0017] By adopting the above technical solution, in actual use, the first driving member drives the reverse thrust rod to telescopically move. Since the stroke of the reverse thrust rod after abutting against the fixed part is greater than the insertion stroke of the charging gun, it can be ensured that the charging gun can be completely disengaged during the reverse push process.

[0018] Preferably, the fixing assembly includes a clamping frame, a contoured clamping portion symmetrically arranged on the clamping frame, and a driving source for driving the symmetrically arranged contoured clamping portion to move in an approaching or moving away direction.

[0019] By adopting the above technical solution, when fixing the charging gun, a driving source is used to cause the symmetrically arranged contoured clamping parts to move relative to each other, thereby clamping the gun body of the charging gun. The relative contoured clamping method is applicable to more types of charging guns.

[0020] Preferably, a non-slip flexible part is elastically provided on one side of the contoured clamping parts that are close to each other.

[0021] By adopting the above technical solution, the anti-slip flexible member elastically arranged on the side where the contoured clamping parts are close to each other is used to improve the adaptability, so that the contoured clamping parts fit the charging gun more closely, and on the other hand, play a certain buffering role.

[0022] Preferably, the fixing assembly includes a fixing frame, the fixing frame is provided with a supporting and limiting groove opening upward, and a supporting and limiting fixation is formed between the supporting and limiting groove and the gun body of the charging gun.

[0023] By adopting the above technical solution, the supporting and limiting grooves provided on the fixing frame are utilized to form a supporting and limiting fixation between the fixing frame and the gun body of the charging gun. This fixing method is simple and convenient, and is also more convenient for users to take.

[0024] Preferably, the cable traveling assembly includes a traveling frame, a traveling anti-skid wheel rotatably arranged on the traveling frame and forming a rolling fit with the cable, a third driving member driving the traveling anti-skid wheel to rotate, and a locking member locking the traveling anti-skid wheel to the cable, and the clamping frame is arranged on the traveling frame.

[0025] By adopting the above technical solution, the third driving member is used to drive the anti-skid wheel to rotate, thereby driving the entire traveling frame to move on the cable, thereby moving the clamping frame along the cable to clamp the tail of the charging gun.

[0026] Preferably, the traveling assembly further comprises an adjusting unit for adjusting the distance between the traveling anti-skid wheels, and the adjusting unit is arranged on the traveling frame.

[0027] By adopting the above technical solution, the adjustment unit is used to adjust the spacing between the anti-skid wheels, which can adapt to cables of different diameters on the one hand, and on the other hand, the clamping force of the anti-skid wheels on the cables can be adjusted, thereby improving the anti-skid performance of the anti-skid wheels.

[0028] The present application also provides a charging device with an automatic gun-releasing traction mechanism adopting the following technical solution:

[0029] A charging device with an automatic gun-detaching traction mechanism includes a shell with a charging unit inside, a frame that is detachably fixed on the shell, a controller that is provided on the frame, and an electrical connection between the controller and the charging system of the charging unit.

[0030] By adopting the above technical solution, the frame of the automatic gun removal traction mechanism is fixed to the shell in a detachable manner, thereby enabling the entire charging device to have the functions of automatically pulling the charging gun and removing the gun.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. The mobile component automatically moves the charging gun to the charging port, eliminating the operator's need to pull the cable. After charging is complete, the reverse push detachment component automatically detaches the charging gun from the charging port, eliminating the operator's need to remove the gun. The mobile component then returns the charging gun to its original position, eliminating the operator's need to return the charging gun, thereby improving the convenience of the entire charging process.

[0033] 2. By leveraging the cable travel component's ability to travel along the line and the fixed component's clamping function, combined with the reverse push-off component, the entire gun removal operation can be automated and adapted to different models of charging guns.

[0034] 3. Through the electrical connection between the controller and the charging unit, the charging system of the charging unit is combined with the mechanical action of the automatic gun-release traction mechanism. That is, the charging device can use the moving components on the automatic gun-release traction mechanism to realize multiple mechanical actions such as welcoming or warning to ensure the safety of the operator during the parking process.

[0042] The following is combined with Figure 1-6 This application is described in further detail.

[0043] The embodiment of the present application discloses an automatic gun release pulling mechanism.

[0044] Example 1

[0045] Reference Figure 1 and Figure 2 An automatic gun-detaching traction mechanism includes a frame 1 and a reverse push-off assembly 2. A moving assembly 3 is provided on the frame 1. The mobile terminal of the moving assembly 3 is provided with a fixing assembly 4 for fixing the charging gun head. The frame 1 is also provided with a cable winding assembly 5 for winding the cable. In the embodiment of the present application, the reverse push-off assembly 2 is provided on the charging gun.

[0046] In actual use, the mobile component 3 moves the fixed component 4 that fixes the charging gun to a position close to the charging port. Then, the operator takes the charging gun at close range and inserts the charging gun into the charging port to perform the charging operation. After charging is completed, the reverse push and separation component 2 on the charging gun separates the charging gun head from the charging port by reverse push on the side of the charging port. Then the cable winding component 5 rewinds the cable. After rewinding, the charging gun is reconnected to the fixed component 4 on the mobile component 3, and then reset to its original position, waiting for the next charging action. The whole process eliminates the action of dragging the charging cable and the action of removing the gun, which greatly simplifies the charging process and improves the convenience of the overall charging operation.

[0047] Reference Figure 1 and Figure 2 , wherein the mobile component 3 can be set as a multi-dimensional mobile robotic arm or a multi-dimensional mobile module and other mobile structures. In the embodiment of the present application, the mobile component 3 is set as a multi-dimensional mobile robotic arm to meet the movement modes such as lifting, translation and rotation to ensure the directional movement of the fixed component 4.

[0048] Reference Figure 1 and Figure 2 The fixing component 4 includes a fixing frame 41, which is detachably fixed to the mobile terminal of the moving component 3 by bolts. A supporting limit groove 411 with an upward opening is provided on the fixing frame 41, and a supporting limit fixation is formed between the supporting limit groove 411 and the gun body of the charging gun. Specifically, in the embodiment of the present application, the supporting limit groove 411 makes the fixing frame 41 have a hollow annular structure. In actual use, the supporting limit groove 411 can be used to play the role of plugging and supporting the handle of the charging gun, thereby realizing the fixing effect of the fixing component 4 on the charging gun.

[0049] Reference Figure 1 and Figure 2 There are two reverse thrust separation components 2 symmetrically arranged, and the two reverse thrust separation components 2 are horizontally symmetrically arranged about the gun head of the charging gun. Since the structure and installation form of any reverse thrust separation component 2 are the same, one of the reverse thrust separation components 2 is now taken as an example for explanation.

[0050] Reference Figure 1 and Figure 2The reverse push disengagement assembly 2 includes a reverse push rod 21 that is telescopically arranged and a first driving member 22 for driving the reverse push rod 21 to telescopically move. In the embodiment of the present application, the first driving member 22 is configured as a telescopic cylinder, and the reverse push rod 21 is fixed on the piston rod of the telescopic cylinder. The reverse push rod 21 acts on a fixed position around the charging port, and a soft rubber pad is fixed to the end of the reverse push rod 21. The telescopic direction of the reverse push rod 21 is consistent with the plugging and unplugging direction of the charging gun head, and the stroke of the reverse push rod 21 after contacting the fixed position is greater than the insertion stroke of the charging gun.

[0051] During the actual disengagement operation, the two first driving members 22 in the two reverse push and release assemblies 2 are activated, driving the two symmetrical reverse push rods 21 to abut against the fixed position around the charging port, thereby reversely disengaging the charging gun from the charging port. In other embodiments of the application, the reverse push and release assembly 2 can also be provided as a single one, and it can be installed inside the charging gun.

[0052] The cable reel assembly 5 includes an auxiliary wheel 51, a reel 52, and a reel motor 53 that drives the reel 52 to rotate. The reel motor 53 is mounted on the frame 1, and the reel 52 is coaxially fixed to the output shaft of the reel motor 53. The auxiliary wheel 51 is rotatably mounted on the frame 1, and a reeling space 521 is formed between the auxiliary wheel 51 and the reel 52. In actual use, the reel motor 53 drives the reel 52 to rotate, and the friction between the reel 52 and the cable drives the cable to reel. In addition to the embodiment of the present application, the cable reel assembly 5 can also adopt a method of clamping the cable for telescopic movement.

[0053] The implementation principle of an automatic gun release traction mechanism in the embodiment of the present application is as follows:

[0054] In actual use, the mobile component 3 drives the fixed component 4 to move, and the charging gun on the fixed component 4 is moved to a position close to the charging port. Then the operator does not need to pull the cable, but only needs to complete the action of inserting the charging gun;

[0055] When charging is completed, the telescopic cylinder drives the reverse thrust rod 21 to act on the fixed position around the charging port, and uses the reverse thrust to separate the charging gun from the charging port. Then, the winding motor 53 drives the winding wheel 52 to rotate, and the cable is wound up, so that the charging gun is reset to the fixed frame 41. Then, the moving component 3 is used to reset the charging gun to its original position and wait for the next action instruction.

[0056] Example 2

[0057] The difference between this embodiment and embodiment 1 is that:

[0058] Reference Figure 1 and Figure 3An automatic gun-detaching traction mechanism also includes a cable traveling assembly 6 arranged on the charging gun cable, a fixed assembly 4 arranged on the cable traveling assembly 6, a reverse thrust disengagement assembly 2 arranged on the fixed assembly 4, and a mobile terminal of the mobile assembly 3 provided with a mounting seat 7, which forms a detachable fixed connection with the cable traveling assembly 6.

[0059] Reference Figure 3 and Figure 4 The cable traveling assembly 6 includes a traveling frame 61 and a traveling anti-skid wheel 62 rotatably arranged on the traveling frame 61. In the embodiment of the present application, there are two traveling frames 61 and two traveling anti-skid wheels 62, and the two traveling anti-skid wheels 62 are rotatably arranged on the two traveling frames 61 respectively. Correspondingly, the two traveling anti-skid wheels 62 are symmetrically arranged on the cable and form a rolling fit with the cable.

[0060] Reference Figure 3 and Figure 4 The cable travel assembly 6 also includes a third drive member 63 for driving the travel anti-skid wheel 62 to rotate and a locking member 64 for locking the travel anti-skid wheel 62 on the cable. In the embodiment of the present application, the third drive member 63 is configured as a drive motor, and the output shafts of the two drive motors are respectively connected to the two travel anti-skid wheels 62 to form a transmission connection. In the embodiment of the present application, a direct-connection transmission connection is adopted to drive the two travel anti-skid wheels 62 to roll on the cable; the locking member 64 is configured as a first pneumatic clamp with a clearance opening in the middle, and the two travel frames 61 are installed on the two movable clamping blocks of the first pneumatic clamp. The clamping and release of the first pneumatic clamp are used to achieve the clamping and release of the cable. In other application embodiments, a buffer can also be provided on the travel frame 61 to achieve a buffering effect between the travel frame 61 and the travel anti-skid wheel 62 to prevent direct action on the cable and damage to the cable.

[0061] In actual use, the locking member 64 is used to drive the two anti-skid wheels 62 to clamp the cable, and then the two driving motors are driven synchronously to achieve walking movement on the cable.

[0062] Reference Figure 3 and Figure 4The fixing assembly 4 also includes a clamping frame 42 and a contoured clamping portion 43 symmetrically arranged on the clamping frame 42, and a driving source 44 for driving the symmetrically arranged contoured clamping portion 43 to move in an approaching or moving away direction. In the embodiment of the present application, the driving source 44 is set as a second pneumatic clamping jaw, which is fixedly mounted on the clamping frame 42. Correspondingly, two contoured clamping portions 43 are symmetrically arranged, and the two contoured clamping portions 43 are respectively fixedly connected to the movable clamping blocks of the second pneumatic clamping jaws. A non-slip flexible part 431 is elastically provided on one side where the two contoured clamping portions 43 are close to each other. In the embodiment of the present application, the non-slip flexible part 431 is set as a rubber pad made of a soft material, wherein a plurality of compression springs are connected between the rubber pad and the contoured clamping portion 43 to achieve an elastic setting between the rubber pad and the contoured clamping portion 43.

[0063] Reference Figure 3 and Figure 4 The first pneumatic clamp is fixed on the side of the clamping frame 42 away from the second pneumatic clamp, wherein the fixing component 4 is located on the side closer to the charging gun head than the traveling cable component, and the clamping frame 42 and the second pneumatic clamp are both provided with corresponding avoidance openings for avoiding the cables.

[0064] Reference Figure 3 and Figure 4 Any reverse thrust disengagement assembly 2 includes a connecting bracket 23 fixed on one side of the clamping frame 42, that is, the two reverse thrust disengagement assemblies 2 are symmetrical on both sides of the clamping frame 42, and the two first driving members 22 are fixed on the two connecting brackets 23, and the two first driving members 22 both telescopically move toward the direction of the charging port and are parallel to the plug-in and unplugging direction of the charging gun.

[0065] Reference Figure 3 and Figure 4 , wherein, an escape opening for avoiding cables is also formed in the mounting seat 7, a detachable fixed fit with a limited card is formed between the clamping frame 42 and the mounting seat 7, and a guide surface is provided at the opening of the mounting seat 7.

[0066] The implementation principle of Example 2 is:

[0067] After the actual charging action is completed, the two driving motors synchronously drive the two anti-skid wheels 62 to move on the cable, and then mobilize the first pneumatic clamp and the second pneumatic clamp to move in the direction close to the tail end of the charging gun handle. When the two anti-skid wheels 62 move to the tail end of the charging gun head and are blocked, the two driving motors brake and lock the two anti-skid wheels 62. Then, the two movable clamping blocks of the second pneumatic clamp drive the two contoured clamping parts 43 to clamp and fix the handle of the charging gun head. Since the two contoured clamping parts 43 are elastically provided with anti-slip flexible parts 431, they can adapt to the handle structures of a variety of charging guns, as long as the opposite sides of the charging gun handle are symmetrically clamped and fixed.

[0068] After the fixation is completed, the first driving member 22 on the two connecting brackets 23 drives the reverse thrust rod 21 to act on the fixed position around the charging port, thereby separating the charging gun from the charging port; after that, the cable reel assembly 5 recycles the cable until the clamping frame 42 is reset to the supporting limit groove 411 in the fixing frame 41. Finally, the first pneumatic clamp and the second pneumatic clamp release the clamping effect, so that the operator can easily remove the charging gun from the fixing frame 41 for charging operation next time.

[0069] The embodiment of the present application also discloses a charging device with an automatic gun-releasing traction mechanism.

[0070] Reference Figure 5 and Figure 6 A charging device with an automatic gun-detaching traction mechanism includes the automatic gun-detaching traction mechanism in Example 1 or Example 2. The embodiment of the present application adopts the automatic gun-detaching traction mechanism in Example 1, and also includes a shell 8 with a charging unit inside. The charging unit can be a traditional fixed charging pile or a mobile charging unit. The frame 1 of the automatic gun-detaching traction mechanism is detachably fixed to the shell 8 by bolts, and a controller 9 is provided on the frame 1. The controller 9 is electrically connected to the charging unit via Bluetooth or a PLC single-chip device to realize signal transmission.

[0071] In actual use, the charging unit in the charging device equipped with an automatic gun-releasing traction mechanism can pre-drive the mobile component 3 in the automatic gun-releasing traction mechanism according to the charging demand information sent by the user, and move the charging gun to the pre-charging position. After receiving the instruction after the vehicle braking is completed, the mobile component 3 can further move the charging gun to a position close to the charging port, and then the driver can directly pick up the charging gun at the charging port after getting off the vehicle.

[0072] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
