Description

Technical Field

[0001] The present invention relates to the field of new energy charging equipment, and in particular to a charging gun controller for a new energy vehicle charging robot. Background Art

[0002] After a period of use, new energy vehicles need to replenish the electricity they consume. In order to improve charging efficiency, charging robots are generally used for operation. When using a traditional new energy vehicle charging robot, the robot arm first drives the grabbing mechanism to grab the charging gun, and the robot arm sends the charging gun to the charging port of the new energy vehicle. A person manually opens the first layer of the charging port protective cover, and then opens the second layer of the charging port protective cover. Finally, the robot arm inserts the charging gun into the charging port. The existing technology still requires manual opening or closing of the charging cover before or after charging, and the degree of automation is low. In view of the above situation, we propose a charging gun controller for a new energy vehicle charging robot.

[0003] Chinese patent CN218594142U discloses a gripping mechanism of a new energy vehicle charging robot. The gripping mechanism utilizes a pressure plate design. The overall pressure plate is in an "arch shape", and the bottom ends of both sides of the pressure plate are in a "convex arc shape". When gripping the charging rod, the suction cup is used for adsorption so that the bottom of the charging rod is located at the opposite end of the two intelligent positioning rods, and the top of the charging rod is pressed against the top of the inner wall of the pressure plate to ensure the stability of the charging rod and prevent the charging rod near the suction cup end from warping when one end of the charging rod is subjected to a downward force, causing the charging rod to detach from the gripping mechanism. However, the patent does not provide a protective pad, which may easily damage the charging gun, and the charging protection cover cannot be opened automatically and needs to be opened manually.

[0004] Chinese patent CN214213513U discloses a multifunctional plug-in clamp for a new energy charging pile. The charging gun clamping mechanism is designed in the clamping mechanism. By turning two knobs respectively, two arc groove clamping blocks are slowly brought closer together to clamp the charging gun between the two arc groove clamping blocks. Since the contact surface between the arc groove clamping block and the charging gun is a large-diameter arc and a protective pad is provided, charging guns of different shapes, models and sizes can be effectively clamped. However, there is also the problem that the charging protection cover cannot be opened automatically and needs to be opened manually.

[0005] In view of the above problems, the present invention proposes a charging gun controller for a new energy vehicle charging robot that can flexibly clamp a charging gun and automatically open a charging protection cover, thereby improving charging operation efficiency and simplifying the operation process for car owners.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-6 As shown, the present invention is a charging gun controller for a new energy vehicle charging robot;

[0039] Embodiment 1:

[0040] It includes: a control mechanism 1 and a charging gun 2. The charging port of the new energy vehicle includes a second-layer charging port protection cover 4, a buckle 3 of the second-layer charging port protection cover and a first-layer charging port protection cover 5; the control mechanism 1 is used to automatically open the first-layer charging port protection cover 5 and the second-layer charging port protection cover 4 to realize the charging action.

[0041] The control mechanism 1 includes a mechanical arm connection plate 1-1, a switch control dial 1-2, a suction cup 1-3, an inflatable flexible airbag 1-4, a fastening screw 1-5 and a circular body 1-6. The mechanical arm connection plate 1-1 and the circular body 1-6 are detachably fixedly connected. A circular through groove 1-8 is provided in the middle part of the circular body 1-6, and the circular through groove 1-8 can allow the charging gun 2 to pass through;

[0042] The inflatable flexible airbags 1-4 are provided with two and are symmetrically fixed on the inner wall of the circular through groove 1-8 by fastening screws 1-5; an electric telescopic rod 1-7 is fixedly connected to the side of the circular body 1-6; a cross plate 1-9 is fixedly connected to the outer wall of the end of the electric telescopic rod 1-7; two suction cups 1-3 are symmetrically fixed on the side of the cross plate 1-9 away from the circular body 1-6; the end of the electric telescopic rod 1-7 is connected to the switch control column 1-2, and the electric telescopic rod 1-7 drives the axial movement of the switch control column 1-2, thereby promoting the movement of the buckle 3 of the second-layer charging port protection cover, and then opening the second-layer charging port protection cover 4.

[0043] In this embodiment, an operating mechanism is provided that can automatically open the double-layer protective cover of the charging port of a new energy vehicle, eliminating the need for manual opening. Specifically, the charger is inserted into the circular through groove 1-8 in the middle of the circular body 1-6, and then the fastening screws 1-5 on both sides are tightened, so that the inflatable flexible airbag 1-4 in the circular through groove 1-8 is concentrated toward the middle, thereby forming a wrapping effect on the charging gun 2, and the position of the inflatable flexible airbag 1-4 can be adjusted by rotating the fastening screws 1-5, thereby adjusting the pressure between the charging gun 2 and the inflatable flexible airbag 1-4. The inflatable flexible airbag 1-4 can adjust the pressure between the charging gun 2 and the outside world during the plugging and unplugging process, reduce the impact force of external objects on the charging gun 2, and increase the service life of the charging gun 2. After the charging gun 2 is installed;

[0044] When in use, hold the charging gun 2, the electric telescopic rod 1-7 is extended first, thereby pushing the horizontal plate 1-9 and the suction cup 1-3 to move toward the charging port, and then one of the suction cups 1-3 is aligned with the first layer of charging port protection cover 5, and the suction cup 1-3 is brought into contact with the first layer of charging port protection cover 5. The electric telescopic rod 1-7 is contracted to drive the suction cup 1-3 to move, and the first layer of charging port protection cover 5 is opened first, and then the suction cup 1-3 structure also provided at the end of the switch control column 1-2 is brought into contact with the second layer of charging protection cover, and the electric telescopic rod 1-7 is contracted, thereby driving the movement of the buckle 3 of the second layer of charging port protection cover, and then opening the second layer of charging port protection cover 4, thereby realizing the opening action of the double-layer protection cover of the charging port of the new energy vehicle. In this process, there is no need to manually operate the opening action of the charging port protection cover, which is convenient and quick;

[0045] The present invention is particularly suitable for disabled drivers with disabled hands, because they cannot operate with both hands at the same time when operating the charging port, and can only open the protective cover of the charging port before inserting the charging gun 2, which greatly increases the instability; while using the present invention, the charging gun 2 can be held in one hand, and then the double-layer protective cover of the charging port can be opened by using the control mechanism 1, and the charging gun 2 can be inserted into the charging port, which is convenient and quick.

[0046] Furthermore, the inflatable flexible airbag 1-4 is provided with a semi-frame structure, and the spacing between the two sides of the semi-frame structure is gradually increased outward, and a plurality of convex ridges 1-10 are provided on the inner side of the semi-frame structure. By providing the inflatable flexible airbag 1-4 with a semi-frame structure, the wrapping area between the two inflatable flexible airbags 1-4 and the charging gun 2 can be increased, thereby improving the clamping effect of the charging gun 2; and the provision of the convex ridges 1-10 can play an anti-slip role, preventing the charging gun 2 in the clamped state from detaching from the circular body 1-6.

[0047] Embodiment 2:

[0048] An anti-slip mechanism 6 is also installed on the side of the circular body 1-6, and the anti-slip mechanism 6 is used to prevent the charging gun 2 from suddenly detaching from the charging port of the new energy vehicle; the anti-slip mechanism 6 includes an anti-slip rod 6-1, and the anti-slip rod 6-1 is rotatably installed on the side of the circular body 1-6, and the top of the anti-slip rod 6-1 is fixedly connected with an anti-slip block 6-2, and the anti-slip block 6-2 is set in a semicircular shape, and a slot 6-3 is opened on one side of the new energy vehicle charging port, and a connected circular groove 6-4 is set at the bottom of the slot 6-3;

[0049] The anti-drop rod 6-1 is fixedly connected with a gear 6-5, the gear 6-5 is meshed with a rack 6-6, the rack 6-6 is slidably installed in a slide groove 6-7 provided on the side of the circular body 1-6, a return spring 6-8 is provided between the bottom wall of the slide groove 6-7 and the rack 6-6, the end of the electric telescopic rod 1-7 is fixedly sleeved with an inclined plate 6-9, the thickness of the inclined plate 6-9 is larger as it is closer to the circular body 1-6, and a containing groove 8 is provided in the circular body 1-6;

[0050] When the rack 6-6 moves from the initial state to the bottom wall of the slide groove 6-7, it just rubs the gear 6-5 to rotate half a circle, thereby driving the anti-slip rod 6-1 and the anti-slip block 6-2 to rotate half a circle, and then the anti-slip block 6-2 is rotated into the lower half of the circular groove 6-4.

[0051] In this embodiment, an anti-slip mechanism 6 is provided to prevent the charging gun 2 from suddenly detaching from the charging port during charging due to sliding of the new energy vehicle or external impact on the cable of the charging gun 2, thereby preventing the charging gun 2 or the charging port from being damaged. Specifically, after the control mechanism 1 opens the double-layer protective cover, the charging gun 2 is held in hand and aligned with the charging port. The slot 6-3 and the anti-slip rod 6-1 on the side wall of the charging port are used as the basis for alignment. The anti-slip block 6-2 and the anti-slip rod 6-1 are inserted into the matching slot 6-3, and then the charging gun 2 is pushed toward the charging port until the charging port and the charging gun 2 are tightly plugged in. At this time, the anti-slip block 6-2 is located at the bottom end of the slot 6-3 and enters the circular groove 6-4. At this time, the electric telescopic rod 1-7 extends from the initial contracted state toward the charging port until the suction cup 1-3 is adsorbed on the periphery of the charging port, and together with the anti-slip rod 6-1, a support structure is formed to protect the connection state of the charging gun 2 and the charging port.

[0052] When the electric telescopic rod 1-7 extends outward, the inclined plate 6-9 also moves outward accordingly. The inclined plate 6-9 is larger on the right and smaller on the left, so it pushes the rack 6-6 in contact with the bottom to slide down while moving. When the rack 6-6 moves from the initial state to the bottom wall of the slide groove 6-7, it just rubs the gear 6-5 to rotate half a circle, thereby driving the anti-slip rod 6-1 and the anti-slip block 6-2 to rotate half a circle, and then the anti-slip block 6-2 is rotated into the lower half of the circular groove 6-4. At this time, the anti-slip rod 6-1 is connected with the anti-slip block 6-2 and the circular groove 6-4. The connection forms a mechanical connection state with the charging port. Even if it encounters the above situation, the charging gun 2 will not suddenly detach from the charging port, forming an effective protection for the charging port and the charging gun 2; when charging is completed, you only need to retract the electric telescopic rod 1-7 to drive the inclined plate 6-9 back to the initial position, and the rack 6-6 will be reset under the action of the reset spring 6-8, and the transmission gear 6-5, the anti-slip rod 6-1 and the anti-slip block 6-2 will turn half a circle upward. At this time, it is in a plug-in sliding state, and you only need to hold the charging gun 2 to pull it out. The rack 6-6 and the slide 6-7 are both arranged in an arc shape, and the rack 6-6 is concentrically arranged with the circular through groove 1-8, and the upper end of the rack 6-6 is in contact with the inclined plate 6-9. Through the above arrangement, under the moving contact between the rack 6-6 and the inclined plate 6-9, the rack 6-6 can slide regularly along the slide 6-7 to achieve the normal rotation of the rubbing gear 6-5.

[0053] A shielding curtain 7 is sleeved between the bodies of the two suction cups 1-3, and the shielding curtain 7 is set to an arched structure with a high middle and low sides. Through the setting of the shielding curtain 7, under outdoor conditions, the shielding curtain 7 can shield the connection between the charging gun 2 and the charging port during the charging process, achieve the purpose of sunshade and rainproof, and improve the safety during charging. The shielding curtain 7 with an arched structure can guide rainwater from the edge to prevent overload damage caused by rainwater accumulation, thereby increasing the service life of the shielding curtain 7;

[0054] After the control mechanism 1 opens the double-layer protective cover, hold the charging gun 2 and align it with the charging port. The slot 6-3 and the anti-dropout rod 6-1 on the side wall of the charging port are used as the basis for alignment. The anti-dropout block 6-2 and the anti-dropout rod 6-1 are inserted into the matching slot 6-3, and then push the charging gun 2 toward the charging port until the charging port and the charging gun 2 are tightly plugged in. At this time, the anti-dropout block 6-2 is located at the bottom of the slot 6-3 and enters the circular groove 6-4. At this time, the electric telescopic rod 1-7 is retracted from the initial The state extends toward the charging port until the suction cup 1-3 is adsorbed on the outer periphery of the charging port, forming a supporting structure together with the anti-drop rod 6-1 to protect the connection state of the charging gun 2 and the charging port; when charging is completed, it is only necessary to retract the electric telescopic rod 1-7 to drive the inclined plate 6-9 back to the initial position, and the rack 6-6 is reset under the action of the reset spring 6-8, and the transmission gear 6-5, the anti-drop rod 6-1 and the anti-drop block 6-2 turn upward half a circle. At this time, they are in the plug-in sliding state, and you only need to hold the charging gun 2 to pull it out.

[0055] Embodiment 3:

[0056] The circular body 1-6 is also provided with a safety mechanism, which is used to protect the charging gun 2 in the charging state. The safety mechanism 9 includes a steel wire rope 9-1. The inclined plate 6-9 is located at one end of the containing groove 8 and fixed with the steel wire rope 9-1. The other end of the steel wire rope 9 passes through the containing groove 8 and the guide wheel 9-2 in sequence and is fixed on the clamping block 9-3. The guide wheel 9-2 is rotatably mounted on the side of the circular body 1-6 away from the inclined plate 6-9.

[0057] A slide rail 9-4 is also provided on the side of the circular body 1-6, and the block 9-3 is slidably connected to the slide rail 9-4. The block 9-3 is movably connected to one end of the support bracket 9-5, and the other end of the support bracket 9-5 is movably connected to another slide rail 9-4. The two slide rails 9-4 are both arranged in an inclined upward structure, and the support bracket 9-5 is provided with a groove 9-6 matching the shape of the charging gun 2.

[0058] A hollow groove 9-7 is provided inside the circular body 1-6, and an emergency fire extinguisher 9-8 is embedded and installed in the hollow groove 9-7. The spray port of the emergency fire extinguisher 9-8 faces the gun head part of the charging gun 2, and the pin of the emergency fire extinguisher 9-8 faces away from the spray port, and the pin of the emergency fire extinguisher is located in a slot 9-9 provided on the side of the circular body 1-6, and a baffle 9-10 is fixedly connected to the side of the support bracket 9-5 close to the slot 9-9, and the baffle 9-10 blocks the slot 9-9 in the initial state, and a connecting spring is provided on the bottom wall of the slide rail 9-4. In this embodiment, in order to solve the problem that the connection between the charging gun 2 and the cable is always in a bent state during charging, which easily causes the connection to be disconnected, the present invention adds a safety mechanism 9 on the basis of the above embodiment, and cooperates with the anti-slip mechanism 8. The movement of the inclined plate 6-9 in the anti-slip mechanism 8 is used to pull the wire rope 9-1. Under the traction provided by the wire rope 9-1, the block 9-3 in the slide rail 9-4 is pulled to move to the left. Since the block 9-3 is hinged to the support bracket 9-5, the block 9-3 pulls the support bracket 9-5, which is originally in a misaligned state, to move to the left until it is just under the charging gun 2. At this time, the groove 9-6 set on the support bracket 9-5 cooperates with the handle of the charging gun 2, so that the support bracket 9-5 forms a supporting effect on the connection between the tail of the charging gun 2 and the cable, keeps the connection in a horizontal state, and prevents the connection from being disconnected and damaged due to long-term bending. and the support bracket 9-5 can also pull the connected baffle 9-10 to move while moving toward the center, thereby exposing the slot 9-9 that is initially blocked, so that in the charging state, the pin portion of the emergency fire extinguisher 9-8 is in an exposed state, allowing the driver to urgently pull out the pin when he finds danger and start the emergency fire extinguisher 9-8. Since the nozzle of the emergency fire extinguisher is facing the gun head of the charging gun 2, it can achieve the effect of emergency fire extinguishing, and prevent possible fire problems in time to prevent the fire from increasing rapidly; it should be noted that the charging gun 2 is equipped with a temperature sensor. Once the temperature sensor recognizes that the set temperature is exceeded, the charging gun 2 can be controlled to cut off the power. When the emergency fire extinguisher 9-8 is used, the pin is pulled out and the switch inside the charging gun 2 is started to cut off the power, thereby taking multiple measures and cooperating with each other to ensure that the possibility of fire during charging is minimized and safety is improved.

[0059] The present invention utilizes the cooperation between the safety mechanism 9 and the anti-detachment mechanism 8, which can not only realize the function of the anti-detachment mechanism 8 itself to prevent the charging gun 2 from suddenly detaching from the charging port, but also utilize the power when the anti-detachment mechanism 8 is started to drive the safety mechanism 9 to work, and pull the support bracket 9-5 to the middle position to achieve the function of just supporting the connection between the tail of the charging gun 2 and the cable line, and at the same time, it can also drive the baffle 9-10 to move to expose the notch 9-9, so as to facilitate the activation of the emergency fire extinguisher 9-8 during charging. In the non-charging state, the safety mechanism 9 does not work, so the baffle 9-10 is in the initial state of blocking the notch 9-9, thereby preventing the emergency fire extinguisher 9-8 from being activated by mistake.

[0060] Working principle of the present invention:

[0061] When in use, hold the charging gun 2, the electric telescopic rod 1-7 is extended first, thereby pushing the horizontal plate 1-9 and the suction cup 1-3 to move toward the charging port, and then one of the suction cups 1-3 is aligned with the first layer of charging port protection cover 5, and the suction cup 1-3 is brought into contact with the first layer of charging port protection cover 5. The electric telescopic rod 1-7 is contracted to drive the suction cup 1-3 to move, and the first layer of charging port protection cover 5 is opened first, and then the suction cup 1-3 structure also provided at the end of the switch control column 1-2 is brought into contact with the second layer of charging protection cover, and the electric telescopic rod 1-7 is contracted, thereby driving the movement of the buckle 3 of the second layer of charging port protection cover, and then opening the second layer of charging port protection cover 4, thereby realizing the opening action of the double-layer protection cover of the charging port of the new energy vehicle. In this process, there is no need to manually operate the opening action of the charging port protection cover, which is convenient and quick;

[0062] The present invention is particularly suitable for disabled drivers with disabled hands, because they cannot operate with both hands at the same time when operating the charging port, and can only open the protective cover of the charging port before inserting the charging gun 2, which greatly increases the instability; while using the present invention, the charging gun 2 can be held in one hand, and then the double-layer protective cover of the charging port can be opened by using the control mechanism 1, and the charging gun 2 can be inserted into the charging port, which is convenient and quick.

[0063] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
