Description

Technical Field

The charging seat of the electric vehicle is a supporting structure of the charging gun. During actual charging, it is necessary to ensure stable power connection. After the charging gun is inserted into the charging seat, the lock hook on the charging gun will be inserted into the slot of the charging seat to lock and position it to ensure stability. Traditional charging seats are widely used due to their advantages such as stable and firm use. The current connection structure of the car charging gun is not convenient for detecting that the charging gun is in place and automatically fits the terminal of the charging gun to connect the power. In the traditional plug-in method, when the terminal is inserted into the charging seat, the spring clip of the charging seat will rub and fit the terminal. The method of using the spring clip to elastically fit the terminal is more worn, the surface coating life is low, the overall service life is short, and it is not convenient for anti-drag protection. It is easy to be damaged by the dragging of the charging gun. It is also not convenient for the charging gun to be automatically ejected. There is a hidden danger of false connection when the charging gun is dragged. Summary of the invention

[0039] In the disclosed embodiment, the connecting support 1 also includes: a dustproof bellows 103 and a buffer tension spring 104. The inner ring of the connecting support frame 101 is fixedly installed with a dustproof bellows 103; a circle of buffer tension spring 104 is fixedly installed on the inner side of the connecting support frame 101; a circle of buffer tension spring 104 is used to pull the charging connection part 3; the swinging mounting part 2 includes: a swinging ball head column 201, a telescopic shaft 202, an axial spring 203 and an axial micro switch 204. The end of the swinging ball head column 201 is sleeved inside the ball sleeve 102; the end of the swinging ball head column 201 is a ball head structure; the telescopic shaft 202 is slidably installed on the swinging ball head column 201; the axial spring 203 is sleeved on the telescopic shaft 202; the axial spring 203 is located between the telescopic shaft 202 and the swinging ball head column 201; the axial micro switch is fixedly installed on the telescopic shaft 202 The charging connection part 3 comprises: a charging seat body 301, an outer sleeve 3011, a locking slot 3012, a ball column 302 and an extrusion ball 303. The charging seat body 301 is fixedly mounted on the telescopic shaft 202. The outer sleeve 3011 is fixedly sleeved on the outer side of the charging seat body 301. The outer sleeve 3011 is fixedly sleeved on the inner ring of the dustproof bellows 103. The outer ring of the outer sleeve 3011 is fixedly mounted on the end of a circle of buffer tension spring 104. A circle of ball columns 302 is fixedly mounted on the back of the charging seat body 301, and extrusion balls 303 are respectively embedded on the circle of ball columns 302. The circle of ball columns 302 corresponds to the extrusion bevel rings 1021 respectively, and the extrusion bevel rings 1021 are used to rotate and press the extrusion balls 303.A locking slot 3012 is provided on the top of the charging seat body 301. The charging connection part 3 can cooperate with the ball head support of the swinging ball head column 201 to achieve skew adaptation when the charging gun is subjected to external force, such as wind force or human dragging. At the same time, the buffer tension spring 104 is used for buffering protection to avoid damage to the structure. If axial pulling occurs, the axial spring 203 can be used for buffering protection. At the same time, the structure adopts an extrusion bevel ring 1021 and a ball column 302, which can automatically control the charging gun to pop out when excessive axial or swing pulling occurs to avoid safety hazards. The structure is simple and the control is direct. When the axial pulling pressure of the charging gun is too large, the charging seat body 301 drives the telescopic shaft 202 to slide on the swinging ball head column 201, and the axial spring 203 performs elastic compression buffering. At the same time, if the charging seat body 301 is pulled to either side by the charging gun and swings, the swinging ball head column 201 The ball sleeve 102 can rotate inside, and the swing ball head column 201 swings, which drives a circle of ball columns 302 and extrusion balls 303 to swing at the same time. If the swing amplitude is too large, the extrusion balls 303 in the swing direction will squeeze the extrusion bevel circle 1021. At this time, the extrusion balls 303 are subject to resistance, but the charging seat body 301 is still being pulled and dragged to one side. At this time, the charging seat body 301 can drive the telescopic shaft 202 to slide outward on the swing ball head column 201 under the extrusion of the bevel of the extrusion bevel circle 1021. At this time, the axial micro switch 204 no longer squeezes the inner side of the swing ball head column 201, and the charging gun is controlled to pop out and the dragging over-standard detection work is realized. This structure can not only ensure the locking stability of the charging gun during normal charging, but also automatically separate the charging gun when dragging with greater pressure occurs, which is safer and more reasonable. The specifications of the axial spring 203 and the buffer tension spring 104 are adjusted according to actual needs. ;

[0040] In the disclosed embodiment, the charging gun pop-up member 4 includes: a pop-up electric push rod 401, a propulsion disk 402 and an in-place micro switch 403.

The structure is automatically controlled, and the thrust disk 402 used can adapt to the end face of the charging gun to ensure that the charging gun is vertically disengaged from the swinging ball head column 201. The automatic pop-up charging gun method of the structure can also ensure stable power connection and avoid skew between the charging gun terminal and the power connection conductive part 6, which may cause safety hazards such as false connection. The in-place microswitch 403 used can be used to detect that the charging gun is in place to avoid problems such as false connection caused by the charging gun being fully in place. After the charging gun is inserted into the charging seat body 301, the end of the charging gun will squeeze the in-place microswitch 403, so that the charging gun can be connected to the power supply after being detected to be in place.

[0041] In the embodiment of the present disclosure, the locking control component 5 includes: a locking pressing arm 501, an unlocking paddle 502 and an unlocking spring 503.

The locking control part 5 can be used to automatically control the locking hook of the charging gun. It can be adapted to the existing charging gun structure without affecting the locking of the charging gun. At the same time, it can automatically release the limit of the charging gun hook and make the hook disengage from the locking slot 3012 to ensure that the charging gun can be ejected. The structure control is flexible and the staff does not need to control it. When the axial microswitch 204 is controlled to be disconnected due to dragging and other factors, the locking electromagnet 504 is also controlled to be powered off. At this time, under the pressure of the unlocking spring 503, the unlocking spring 503 squeezes the unlocking paddle 502 to pry the locking hook of the charging gun, and the charging pile hook is disengaged from the locking slot 3012, which is convenient for the charging gun to be ejected. When the charging gun is inserted into the charging seat body 301, the locking hook of the charging gun is just below the locking pressing arm 501.

[0042] Embodiment 2, on the basis of embodiment 1, the electrical connection member 6 comprises: an electrical connection cylinder 601, an extrusion sleeve 602 and a fitting electromagnet 603, the electrical connection cylinder 601 is fixedly installed on the charging seat body 301; the electrical connection cylinder 601 is internally slidably sleeved with an extrusion sleeve 602; the inner side of the extrusion sleeve 602 is a slope structure; the electrical connection cylinder 601 is internally fixedly sleeved with a fitting electromagnet 603, and the fitting electromagnet 603 is located on the outer side of the extrusion sleeve 602; the electrical connection member 6 also comprises: a magnetic ring 6031 and a reset spring 604, A magnetic ring 6031 is fixedly sleeved on the outside of the extrusion sleeve 602; the magnetic ring 6031 is aligned with the fitting electromagnet 603; the fitting electromagnet 603 is used to magnetically attract the magnetic ring 6031; a reset spring 604 is sleeved inside the electrical connection tube 601; the reset spring 604 is located between the electrical connection tube 601 and the extrusion sleeve 602; the expansion electrical connection part 7 includes: an expansion fixing ring 701 and an electrical connection spring 702, the electrical connection tube 601 is fixedly sleeved with the expansion fixing ring 701, and a circle of electrical connection springs 702 is fixedly installed on the expansion fixing ring 701 02, and there are intervals between the circle of power-connecting spring pieces 702; the inner sides of the circle of power-connecting spring pieces 702 are inclined structures; the circle of power-connecting spring pieces 702 are respectively attached to the inner sides of the extrusion sleeves 602; the circle of power-connecting spring pieces 702 are used to fit the terminals of the charging gun, and the expansion power-connecting part 7 is adopted, which can cooperate with the power-connecting conductive piece 6 to realize the expansion power-connecting work. In the power-connecting method of this structure, when the charging gun is inserted into the charging seat body 301, the terminal of the charging gun will not rub against the power-connecting spring piece 702, and the power-connecting spring piece 702 can be automatically controlled to shrink after the charging gun is in place. The power connection work can effectively reduce wear, protect the surface coating, and increase the service life. At the same time, the shrinking power connection structure adopted in this structure can ensure that a circle of power connection springs 702 can contact the terminals of the charging gun to prevent poor contact, ensure the safety of power connection, and prevent overheating. For the currently frequently used outdoor general charging guns and their own power connection springs 702, the life of the power connection springs 702 is improved, and the electromagnet 603 is electromagnetically sucked and squeezed through the sliding sleeve 602, driving the power connection springs 702 to shrink inward and fit on the terminals of the charging gun. At this time, the circuit can be connected.

[0043] The working principle of this embodiment is as follows: First, the four through holes on the connecting support frame 101 are used to pass bolts to install on the vehicle. After the charging gun is inserted into the charging seat body 301, because the charging gun has a locking structure, if the charging gun only shakes slightly, the swing ball head column 201 can rotate inside the ball sleeve 102 to swing and adapt. When the axial pulling pressure of the charging gun is too large, the charging seat body 301 drives the telescopic shaft 202 to slide on the swing ball head column 201, and the axial spring 203 performs elastic compression and buffering. At the same time, if the charging seat body 301 is tilted to any direction by the charging gun, The charging stand body 301 is pulled to one side and swings. At this time, the swinging ball head column 201 can rotate inside the ball sleeve 102, and the swinging ball head column 201 swings, which drives a circle of ball columns 302 and extrusion balls 303 to swing at the same time. If the swing amplitude is too large, the extrusion balls 303 in the swinging direction will be squeezed to the extrusion ramp circle 1021. At this time, the extrusion balls 303 are resisted, but the charging stand body 301 is still pulled and dragged to one side. At this time, the charging stand body 301 can drive the telescopic shaft 202 to slide outward on the swinging ball head column 201 under the extrusion of the inclined surface of the extrusion ramp circle 1021. When the axial micro switch 204 is not squeezed, the circuit can be disconnected. At this time, the two pop-up electric push rods 401 push the propulsion disk 402 to move the pop-up charging gun under the control of their own controller; when the charging gun is inserted into the charging seat body 301, the charging seat body 301 can be manually pulled outward to drive the axial micro switch 204 to no longer squeeze the inner side of the swing ball head column 201. It can also be controlled by the vehicle computer to lock the electromagnetic lock only when charging is in progress. The electromagnet 504 is energized, which is the same as the locking structure on the existing vehicle. When the axial micro switch 204 is controlled to be disconnected due to factors such as dragging, the locking electromagnet 504 is also controlled to be de-energized. At this time, under the compression of the unlocking spring 503, the unlocking spring 503 squeezes the unlocking paddle 502 to toggle the lock hook of the charging gun, and the charging pile lock hook is disengaged from the locking slot 3012, so that the charging gun is ejected. Similarly, when the charging seat body 301 is in a normal state, the locking electromagnet 504 magnetically attracts the locking pressing arm 501, and the locking pressing arm 501 will press the lock head down to position it to ensure the locking effect;

[0044] When the charging gun is inserted into the charging seat body 301 and the micro switch 403 is squeezed into place, it means that the charging gun terminal is in place. After the micro switch 403 is pressed, it controls the fitting electromagnet 603 to pass the electromagnetic suction and squeeze the sleeve 602, driving the power connection spring 702 to shrink inward and fit on the terminal of the charging gun. At this time, the circuit can be connected. After the subsequent charging is completed, the vehicle computer controls the locking electromagnet 504 to cut off the power. When the charging gun is pulled out, the micro switch 403 is no longer squeezed, the fitting electromagnet 603 can be powered off, and under the pressure of the reset spring 604, the squeezing sleeve 602 is controlled to reset.
