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 implementation manners

[0034] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in the present invention are only based on the drawings of the present invention, and they do not specifically limit the present invention.

[0035] Embodiment 1

[0036] As Figures 1 to 10 shown, the present invention provides a charging gun with a bullet - detachable gun head, which specifically includes a gun body 1, a control module 2, a retraction mechanism 6 and a protection mechanism 7

[0037] Among them, a control module 2 is arranged inside the gun body 1, a plug 3 is arranged at the head of the gun body 1, and a plurality of electric wires 4 are connected between the plug 3 and the control module 2. A latch 5 is rotatably arranged inside the top of the gun body 1 for the normal use of the charging gun;

[0038] Among them, the retraction mechanism 6 is arranged between the gun body 1 and the plug 3 for quickly retracting the plug 3 into the gun body 1;

[0039] Among them, the protection mechanism 7 is arranged inside the head of the gun body 1 for assisting the charging gun to eject and protecting the plug 3.

[0040] The retraction mechanism 6 specifically further includes an electric push rod 601, a positioning sensor 602, a top block 604 and a first elastic member 605;

[0041] Among them, multiple electric push rods 601 are evenly spaced inside the gun body 1. The electric push rods 601 are electrically connected to the control module 2. 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 retracts into the gun body when it is necessary to disconnect the charging gun from the vehicle;

[0042] Among them, a positioning sensor 602 is arranged inside the gun body 1. The positioning sensor 602 is electrically connected to the control module 2 and is used to position the charging gun;

[0043] Among them, a first sliding groove 603 is opened at a position on the inner side of the gun body 1 close to the lock 5. A top block 604 is slidably arranged in the first sliding groove 603. Both ends of the top block 604 are in contact and cooperation with the lock 5 and the plug 3 respectively. A first elastic member 605 is arranged between the top block 604 and the first sliding groove 603, which is used to quickly release the lock between the charging gun and the vehicle charging port when it is necessary to disconnect the charging gun from the vehicle.

[0044] The protection mechanism 7 specifically further includes a protection frame 702, a first gear 705, a first rack 707, a second gear 708 and a second rack 710;

[0045] Among them, a second sliding groove 701 is opened at the head section of the gun body 1. The protection frame 702 is slidably arranged in the second sliding groove 701. A plurality of second elastic members 703 are evenly spaced and connected between the protection frame 702 and the second sliding groove 701, which are used to protect the plug 3 when the charging gun is not connected to the vehicle;

[0046] Among them, fixing seats 704 are arranged at positions near the end faces in the middle of both sides inside the gun head. The first gear 705 is rotatably arranged inside the fixing seats 704. First square grooves 706 are opened on the sides of the plug 3 close to the two fixing seats 704. First racks 707 are arranged in the first square grooves 706 respectively. The movement of the plug 3 can drive the first racks 707 to engage with the first gear 705. Second gears 708 with diameters larger than that of the first gear 705 are arranged at both ends of the first gear 705. Second square grooves 709 are opened at positions on the inner side of the protection frame 702 close to the second gears 708. Second racks 710 are arranged in the second square grooves 709 respectively. The second racks 710 are engaged with the adjacent second gears 708. When the plug 3 is in a normal use state, the protection frame 702 can freely move in the second sliding 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 engages with the first gear, and finally controls the protection frame 702 to extend out of the second sliding groove at the same speed, assisting the charging gun to pop out while providing complete protection for the plug.

[0047] Exemplarily, during normal use, the electric push rod 601 controls the plug 3 to be located at the outermost end of the gun body 1. The lock 5 can normally lock the gun body 1 on the vehicle charging port, and the first rack 707 on the plug 3 does not contact the first gear 705. The protection frame 702 is kept in a state of being ejected from the second chute 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 vehicle charging port. The plug 3 is inserted, and the protective shell is pressed into the second chute 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 703 is compressed, and the vehicle charges normally. The position 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 the vehicle to move, when the position 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 activates the electric push rod 601 and controls the telescopic rod of the electric push rod 601 to drive the plug 3 to contract inward towards the gun body 1. When the plug 3 moves past the top block 604, the plug 3 will upwardly press the ejector rod, and the ejector rod compresses the first elastic member 605 and moves upward to lift the lock 5, so that the lock 5 no longer locks the charging gun and the vehicle charging port. At the same time, the plug 3 drives the first rack 707 to move into the gun body 1. 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, it drives the protection frame 702 to extend out of the second chute 701 and press against the vehicle charging port through the second gear 708 and the second rack 710, assisting the charging gun to disconnect from the vehicle and protecting the plug 3 after disconnection. During the above process, by detecting and judging the position of the charging gun and controlling whether the charging gun performs an ejection operation, it can effectively control the dropping position of the charging gun when it ejects to be within the charging position range, avoiding falling onto the driving lane and causing secondary damage to the charging gun. At the same time, the speed of the vehicle from starting to driving away from the charging position is not fast, and the method of controlling ejection by detecting the position can minimize the pulling of the charging gun and the charging pile cable, protecting the cable. Moreover, by setting the diameter ratio of the second gear 708 to the first gear 705, it is possible to reduce the retraction distance of the plug 3 while ensuring the complete extension of the protection frame 702, so that even if the plug 3 retracts into the gun body 1 by a small distance, it can still eject and protect the gun body 1 through the protection frame 702, which not only saves the space required inside the gun body 1 but also avoids damage caused by repeated bending of the wire 4 between the plug 3 and the controller.

[0048] Embodiment 2

[0049] As Figures 9 to 11 shown, on the basis of Embodiment 1, it further includes a guiding mechanism 8. The guiding mechanism 8 specifically includes a mounting frame 801, a limiting frame 802, a guiding rod 803, and a spherical ejector rod 804;

[0050] Among them, a mounting bracket 801 is snap-connected between the connecting plug 3 and the wire 4 of the control module 2. A limiting frame 802 is sleeved on each wire 4. The limiting frame 802 slidably penetrates through the mounting bracket 801. A guide rod 803 facing the plug 3 is provided on one side of the mounting bracket 801 close to the control module 2. A spherical head push rod 804 is slidably sleeved on the guide rod 803. The spherical head end of the spherical head push rod 804 contacts the limiting frame 802, and the other end is connected to the plug 3.

[0051] The mounting bracket 801 between the wires 4 can limit the relative positions of the wires 4. In the initial state, the plug 3 is located at the end of the gun body 1. The limiting frames 802 are all contracted to the position inside the mounting bracket 801 under the drive of the wires 4, and the spherical head push rod 804 does not contact the limiting frame 802 either. When the plug 3 retracts towards the inside of the gun body 1, the spherical head push rod 804 moves along the guide rod 803 towards the limiting frame 802 under the drive of the plug 3 and squeezes the limiting frame 802. The arc surface of the spherical head push rod 804 contacts the limiting frame 802, and the limiting frame 802 is extruded and moved out of the mounting bracket 801, and then drives the wire 4 to bend. When the plug 3 extends, the arc of the spherical head push rod 804 gradually disengages from the limiting frame 802, and the wire 4 is pulled back to the initial state, and the limiting frame 802 retracts to the position inside the mounting bracket 801 again. In this way, the purpose of controlling the bending direction and degree of the wire 4 when the plug retracts is achieved, avoiding the extrusion damage caused by the irregular bending of multiple wires 4, and at the same time facilitating the adjustment and setting of the internal space position of the gun body 1.

[0052] As Figures 12 to 14 shown, on the basis of Embodiment 1, a limiting mechanism 9 is further included. The limiting mechanism 9 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 inside the protection frame 702. The rotating sleeve 902 is rotatably provided in each groove 901. A torsion spring 903 is provided at the rotational connection of the rotating sleeve 902 and the protection frame 702. The top plate 904 is slidably provided inside the rotating sleeve 902. A third elastic member 905 is provided between the top plate 904 and the rotating sleeve 902.

[0053] When the protection frame 702 is located in the second sliding 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 extends, the rotating sleeve 902, under the action of the torsion spring 903, rotates and lifts the top plate 904 out of the groove 901, and finally keeps perpendicular to the protection frame 702 and the plug 3. When the gun body 1 is collided, while the protection frame 702 protects the plug 3, the impact on the plug 3 is reduced, and even if part of the protection frame 702 is broken, it can still provide an elastic protection effect for the plug 3.

[0054] As Figure 15 and Figure 16As shown, on the basis of Embodiment 1, it specifically further includes a clamping block 11, a fourth elastic member 12, and an electromagnet group 13. A plurality of third sliding grooves 10 are evenly spaced at positions on the annular side surface of the plug 3 that are in contact with the inner side of the gun body 1. A clamping block 11 is slidably provided in each of the third sliding grooves 10. A plurality of shallow grooves 1001 are evenly spaced at positions on the inner side of the gun body 1 near the cross-section. The third sliding grooves 10 correspond to the shallow grooves 1001 one by one. The clamping block 11 is in contact and cooperation with the shallow groove 1001. A third elastic member 905 is provided between the clamping block 11 and the third sliding groove 10. An electromagnet group is provided inside the clamping block 11 and the third sliding groove.

[0055] 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 activated. Under the action of the fourth elastic member 12, the clamping block 11 extends out of the third sliding groove 10 and enters the shallow groove 1001, achieving the purpose of fixing and limiting the plug 3, and reducing the burden on the electric push rod 601 when connecting the plug 3 to the vehicle. When it is necessary to eject the plug 3, the controller first activates the electromagnet group 13, so that the electromagnet on the clamping block 11 attracts the electromagnet in the third sliding groove 10, controlling the clamping block 11 to compress the fourth elastic member 12 and return to the third sliding groove 10, facilitating the plug 3 to be driven by the electric push rod 601 to move freely.

[0056] As Figure 1 shown, on the basis of Embodiment 1, it further includes a light strip 14, and the light strip 14 is provided on the outer side of the gun body 1.

[0057] The light strip 14 on the outer side of the gun body 1 remains lit during use, so that when the gun head pops out, even if the light in the surrounding environment is dim, other users can quickly find the position of the charging gun, avoiding secondary damage to the charging gun.
