Description

Technical Field

[0001] The present invention relates to the technical field, and in particular to a charging gun with a gun head ejecting type. Background Art

[0002] The charging gun, also known as the vehicle charging gun, is used to insert into electric vehicles for charging. It is one of the important accessories of the new energy charging pile. When using the charging pile, the user only needs to insert the charging gun into the car's charging port, and then operate the charging pile to charge.

[0003] At present, although conventional new energy charging piles can adjust the charging speed according to the car model and needs, it still takes a certain amount of time to fully charge the car even in fast charging mode, and the charging work does not require additional manual operation, so it is very easy for the driver to become sleepy, or forget the charging event itself and focus on other things. Once the charging is completed or the charging time is over, or the driver encounters an emergency, it is very likely that the driver will drive away directly and forget to unplug the charging gun; and since the charging gun is equipped with a locking device, when the vehicle drives away, the locking device has not been unlocked, and the charging gun cannot be detached from the vehicle, which can easily cause damage to the charging gun and even cause serious safety accidents.

[0004] In order to solve the above-mentioned problems, the Chinese patent with patent number CN108718019A provides a gun head ejection type charging gun, including a gun body with an inner cavity, a plug, a locking piece and a wiring harness. The gun body is provided with a wedge block which slides perpendicular to the length direction of the ejector rod, and the ejector rod is provided with a slot. The wedge block is provided with a first spring. Under the elastic force of the first spring, the wedge end of the wedge block slides into the slot, and the ejector rod is connected to the gun body via the force storage spring; a plug sleeve is slidably inserted on the gun body, and a pull rope is provided in the inner cavity, one end of the pull rope is connected to the wedge block, and the other end of the pull rope is connected to the plug sleeve; the wiring harness is fixedly connected to the plug sleeve, and one end of the wiring harness is placed in the inner cavity and connected to the plug. When in use, it can ensure that the charging gun is subjected to tension in an emergency and is safely ejected from the vehicle, effectively avoiding the situation where the charging gun and the charging interface are damaged, or the wiring harness is directly broken to cause a safety accident.

[0005] Although the above patent can achieve the effect of quickly and safely ejecting the charging gun from the vehicle when it is subjected to pulling force, the charging cable of a conventional charging pile is relatively long. When the charging gun is subjected to pulling force, the charging gun has already moved away from the charging pile to the lane, and is very susceptible to being crushed by other passing vehicles. At the same time, the ejector rod in the above patent is normally retracted in the gun body, so that the force storage spring remains in a compressed state for a long time. If it is not relaxed from time to time, the use effect of the force storage spring will be greatly affected, and it may even happen that the force storage spring cannot push the ejector rod to eject the gun head from the car.

[0006] Therefore, it is necessary to design a gun head ejection type charging gun which can protect the gun head and limit the ejection position. Summary of the invention

[0007] In order to overcome the problem that when the existing charging gun is ejected by pulling force, the charging gun has been away from the charging pile and is on the lane, and is very susceptible to being crushed by other passing vehicles. At the same time, the force storage spring is kept in a compressed state for a long time. If it is not relaxed from time to time, the use effect of the force storage spring will be greatly affected, and even the force storage spring may be unable to push the ejector rod to eject the gun head from the car.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0035] Example 1 like Figures 1 to 10 As shown, the present invention provides a charging gun with a gun head ejection type, which specifically includes a gun body 1, a control module 2, a retracting mechanism 6 and a protection mechanism 7. Among them, a control module 2 is provided inside the gun body 1, a plug 3 is provided at the head of the gun body 1, a plurality of wires 4 are connected between the plug 3 and the control module 2, and a lock 5 is rotatably provided inside the top of the gun body 1 for normal use of the charging gun; The retracting mechanism 6 is arranged between the gun body 1 and the plug 3, and is used to quickly retract the plug 3 into the gun body 1; The protection mechanism 7 is arranged inside the head of the gun body 1 to assist the charging gun in ejecting and protect the plug 3 .

[0036] The retracting mechanism 6 specifically includes an electric push rod 601, a positioning sensor 602, a top block 604 and a first elastic member 605; Among them, a plurality of electric push rods 601 are evenly spaced and arranged inside the gun body 1, the electric push rods 601 are electrically connected to the control module 2, and the telescopic rods of the electric push rods 601 are all connected to the plug 3 and drive the plug 3 to slide inside the gun head, so that the plug 3 is retracted into the gun body when the connection between the charging gun and the car needs to be disconnected; Among them, a positioning sensor 602 is arranged inside the gun body 1, and the positioning sensor 602 is electrically connected to the control module 2, and is used to locate the position of the charging gun; Among them, a first slide groove 603 is opened on the inner side of the gun body 1 near the lock buckle 5, and a top block 604 is slidably arranged in the first slide groove 603. The two ends of the top block 604 are respectively in contact with the lock buckle 5 and the plug 3. A first elastic member 605 is arranged between the top block 604 and the first slide groove 603, which is used to quickly release the lock between the charging gun and the charging port of the car when it is necessary to disconnect the charging gun from the car.

[0037] The protection mechanism 7 specifically includes a protection frame 702, a first gear 705, a first rack 707, a second gear 708 and a second rack 710; A second slide groove 701 is formed on the head section of the gun body 1, a protection frame 702 is slidably disposed in the second slide groove 701, and a plurality of second elastic members 703 are evenly spaced and connected between the protection frame 702 and the second slide groove 701, for protecting the plug 3 when the charging gun is not connected to the car; Among them, a fixing seat 704 is provided at the middle part of both sides of the gun head near the end surface, and the first gear 705 is rotatably arranged on the inner side of the fixing seat 704. The sides of the plug 3 close to the two fixing seats 704 are provided with a first square groove 706, and the first square groove 706 is provided with a first rack 707. The movement of the plug 3 can drive the first rack 707 to engage with the first gear 705. The two ends of the first gear 705 are provided with a second gear 708 with a diameter larger than the first gear 705. The inner side of the protective frame 702 close to the second gear 708 is A second square groove 709 is opened, and a second rack 710 is provided in the second square groove 709. The second rack 710 is meshed with the adjacent second gear 708. When the plug 3 remains in normal use, the protection frame 702 can move freely in the second slide groove 701 to protect the plug 3 without affecting the use of the plug. When the plug 3 retracts into the gun body 1, the first rack gradually approaches and meshes with the first gear, and finally controls the protection frame 702 to extend from the second slide groove at the same speed, and the auxiliary charging gun is ejected while fully protecting the plug.

[0038] Exemplarily, during normal use, the electric push rod 601 controls the plug 3 to be located at the end of the gun body 1, and the lock buckle 5 can normally lock the gun body 1 on the car charging port, while the first rack 707 on the plug 3 does not contact the first gear 705, and the protective frame 702 remains ejected from the second slide groove 701 under the action of the second elastic member 703 to protect the plug 3. When charging, the user inserts the charging gun into the car charging port, the plug 3 is inserted, and the protective shell is pressed into the second slide groove 701. At this time, the first rack 707 does not mesh with the first gear 705, and will not affect the position of the plug 3. The second elastic member 70 3 is compressed, the vehicle is charged normally, and the positioning sensor 602 of the charging gun continuously detects the position of the charging gun. If the user forgets to remove the charging gun and starts to move the car, when the positioning sensor 602 detects that it has left the normal charging range or the distance from the charging pile exceeds a certain value, the control module 2 immediately starts the electric push rod 601 to control the telescopic rod of the electric push rod 601 to drive the plug 3 to retract toward the inside of the gun body 1. When the plug 3 moves past the top block 604, the plug 3 will squeeze the push rod upward, and the push rod compresses the first elastic member 605 to move upward, pushing up the lock buckle 5, so that the lock buckle 5 no longer locks the charging gun and the car charging port. At the same time, the plug 3 drives the first elastic member 605 to move upward, pushing up the lock buckle 5, so that the lock buckle 5 no longer locks the charging gun and the car charging port. A rack 707 moves into the gun body 1, and the first rack 707 will gradually approach the first rack 707 and finally drive the first gear 705 to rotate. While the first gear 705 rotates, the second gear 708 and the second rack 710 drive the protection frame 702 to extend from the second slide groove 701 and push against the charging port of the car, so as to disconnect the auxiliary charging gun from the car and protect the plug 3 after disconnection. In the above process, by detecting and judging the position of the charging gun and controlling whether the charging gun is ejected, the falling position of the charging gun when it is ejected can be effectively controlled to be kept within the charging position range, so as to avoid falling onto the lane and causing damage to the charging gun. Secondary injury is not caused. At the same time, the speed of the car from starting to leaving the charging position is not fast. The method of controlling the pop-up by detecting the position can minimize the pulling of the charging gun and the charging pile cable and protect the cable. Moreover, by setting the diameter ratio of the second gear 708 to the first gear 705, the retraction distance of the plug 3 can be reduced while ensuring that the protection frame 702 is fully extended, so that even if the plug 3 is retracted into the gun body 1 for a short distance, the gun body 1 can be ejected and protected by the protection frame 702, that is, the space required inside the gun body 1 is saved and the damage caused by repeated bending of the wire 4 between the plug 3 and the controller can be avoided.

[0039] Example 2 like Figures 9 to 11 As shown, on the basis of embodiment 1, a guiding mechanism 8 is further included, and the guiding mechanism 8 specifically includes a mounting frame 801, a limiting frame 802, a guide rod 803 and a ball head push rod 804; Among them, a mounting bracket 801 is provided in a snap-fitting manner between the wires 4 connecting the plug 3 and the control module 2, and a limit frame 802 is sleeved on each wire 4. The limit frame 802 slides through the mounting bracket 801, and a guide rod 803 facing the plug 3 is provided on the side of the mounting bracket 801 close to the control module 2. A ball head push rod 804 is slidably sleeved on the guide rod 803, and the ball head end of the ball head push rod 804 is in contact with the limit frame 802, and the other end is connected to the plug 3.

[0040] The mounting frame 801 between the wires 4 can limit the relative position of the wires 4. In the initial state, the plug 3 is located at the end of the gun body 1, and the limit frame 802 is retracted to the position inside the mounting frame 801 driven by the wire 4, and the ball head push rod 804 does not contact the limit frame 802. When the plug 3 retracts to the inside of the gun body 1, the ball head push rod 804 moves along the guide rod 803 to the limit frame 802 under the drive of the plug 3 and squeezes the limit frame 802. The arc surface of the ball head push rod 804 is in contact with the limit frame 802. When the plug 3 is extended, the arc of the ball head push rod 804 gradually loses contact with the limit frame 802, and the wire 4 is pulled back to the initial state. The limit frame 802 shrinks to the position inside the mounting frame 801 again, so as to achieve the purpose of controlling the bending square and degree of the wire 4 when the wiper head retracts, avoiding extrusion damage caused by irregular bending of multiple wires 4, and facilitating the adjustment and setting of the internal space position of the gun body 1.

[0041] like Figure 12 to Figure 14 As shown, on the basis of Example 1, it also includes a limiting mechanism 9, which specifically includes a rotating sleeve 902, a torsion spring 903, a top plate 904 and a third elastic member 905. A plurality of grooves 901 are evenly spaced apart on the inner side of the protective frame 702. The rotating sleeve 902 is rotatably arranged in the grooves 901. A torsion spring 903 is arranged at the rotating connection between the rotating sleeve 902 and the protective frame 702. A top plate 904 is slidably arranged on the inner side of the rotating sleeve 902. A third elastic member 905 is arranged between the top plate 904 and the rotating sleeve 902.

[0042] When the protection frame 702 is located in the second slide groove 701, the rotating sleeve 902 and the top plate 904 are both rotated and contracted in the groove 901, and the torsion spring 903 is deformed. When the protection frame 702 is extended, the rotating sleeve 902 is rotated and lifted out of the groove 901 with the top plate 904 under the action of the torsion spring 903, and finally maintains a vertical state with the protection frame 702 and the plug 3. When the gun body 1 is collided, the protection frame 702 protects the plug 3 while reducing the impact on the plug 3. Even if the protection frame 702 is partially broken, it can still provide elastic protection for the plug 3.

[0043] like Fig.15 and Fig.16As shown, on the basis of Example 1, it specifically includes a clamping block 11, a fourth elastic member 12 and an electromagnet group 13, a plurality of third slide grooves 10 are evenly spaced at the position on the annular side of the plug 3 that contacts the inner side of the gun body 1, and a clamping block 11 is slidably provided in the third slide groove 10, a plurality of shallow grooves 1001 are evenly spaced at the position near the cross section on the inner side of the gun body 1, the third slide groove 10 corresponds to the shallow groove 1001 one by one, the clamping block 11 is in contact with the shallow groove 1001, a third elastic member 905 is provided between the clamping block 11 and the third slide groove 10, and a battery iron group is provided inside the clamping block 11 and the third slide groove 10.

[0044] In the initial state, the plug 3 is located at the end of the gun body 1. At this time, the electromagnet group 13 is not started, and the block 11 extends from the third slide groove 10 into the shallow groove 1001 under the action of the fourth elastic member 12, so as to achieve the purpose of fixing and limiting the plug 3. When the plug 3 is connected to the car, the burden of the electric push rod 601 is reduced. When the plug 3 needs to be ejected, the controller first starts the electromagnet group 13, so that the electromagnet on the block 11 and the electromagnet in the third slide groove 10 attract each other, and controls the block 11 to compress the fourth elastic member 12 back into the third slide groove 10, so that the plug 3 is driven by the electric push rod 601 to move freely.

[0045] like Figure 1 As shown, based on the embodiment 1, a light belt 14 is further included. The light belt 14 is arranged on the outside of the gun body 1 .

[0046] The light strip 14 on the outside of the gun body 1 remains lit during use, so that when the gun head pops out, even if the surrounding light is dim, other users can quickly find the location of the charging gun to avoid secondary damage to the charging gun.
