Description

Technical Field

[0001] This invention relates to the field of charging gun technology, specifically to an AC charging gun for electric vehicles. Background Technology

[0002] The charging gun is a key component connecting the charging station and the electric vehicle, responsible for transmitting electrical energy and ensuring safe charging. Based on the charging type, it is mainly divided into AC charging guns (AC) and DC charging guns (DC). AC charging guns are suitable for home charging stations and public slow charging stations, where the on-board charger (OBC) converts AC power to DC power to charge the battery. DC charging guns, on the other hand, directly output high-voltage DC power through public fast charging stations (such as highway charging stations), bypassing the on-board charger.

[0003] Patent No. 201811440081.1 discloses a problem with an AC charging gun for electric vehicles, including a charging gun head and a charging interface. A fixing rod is provided at the lower right side of the charging gun head, and a threaded connecting post is provided at the lower end of the fixing rod. A threaded power cable is sleeved inside the threaded connecting post. Because of the threaded power cable and threaded connecting post, when the fixed power cable is damaged or broken during charging, the operator can rotate the fixing block in the threaded power cable to rotate and separate the external threaded fixing post in the threaded power cable from the internal threaded body inside the fixed conical post. At the same time, the signal post will separate from the signal connecting post, thus allowing the threaded power cable to rotate and separate from the threaded connecting post. This facilitates the replacement of the threaded power cable and avoids damage to the entire AC charging gun. This not only improves the efficiency of power cable replacement but also reduces property damage.

[0004] The aforementioned applications, using components such as threaded power cords and threaded connecting posts, fail to effectively dissipate heat during the charging process, resulting in excessive heat and potential safety hazards. Therefore, this paper proposes an AC charging gun for electric vehicles to address these issues. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an AC charging gun for electric vehicles, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: an AC charging gun for electric vehicles, including a gun body, an output port provided on the side of the gun body, a handle fixedly connected to the side of the gun body, and a simultaneous air-cooling and water-cooling heat dissipation device provided on the outer surface of the gun body; the simultaneous air-cooling and water-cooling heat dissipation device includes a water-cooled box, an adjusting column rotatably connected to the bottom of the water-cooled box, a connecting seat fixedly connected to the circumferential surface of the adjusting column, an air-cooled box fixedly connected to the side of the connecting seat, an air-cooled fan fixedly connected to the inner side of the air-cooled box, a heat dissipation vent opened on the side of the air-cooled box, a water-cooling patch fixedly connected to the bottom of the connecting seat, an arc-shaped flexible tube fixedly connected to the side of the water-cooling patch, one end of the arc-shaped flexible tube fixedly connected to the bottom of the adjusting column, a five-lobed adjusting blade fixedly connected to the top of the inner wall of the adjusting column, a water inlet opened on the top of the water-cooled box, and an adaptive lobe fixedly connected to one end of the water inlet.

[0007] Preferably, a small gear is fixedly connected to the outer surface of the adjusting column, a locking plate is slidably connected to the bottom of the water-cooled box, and a locking block is fixedly connected to the side of the locking plate. In the initial state, the adjusting column is engaged with the locking block. The actual size of the locking block matches the teeth of the small gear to ensure that the rotation angle of the adjusting column is locked at this time. When it is necessary to adjust the rotation angle of the adjusting column, the user can pull out the locking plate to disengage the locking block from the small gear. After rotating the adjusting column to the appropriate angle, the locking plate is released. The locking block, under the elastic potential energy of the return spring, engages with the small gear and locks itself in the adjusted position. Under normal conditions, the locking plate can slide to avoid gear rotation.

[0008] Preferably, a return spring is fixedly connected to the side of the card plate, one end of the return spring is fixedly connected to a spring fixing plate, and the top of the spring fixing plate is fixedly connected to the bottom of the water-cooling tank. The return spring is designed to adaptively adjust the rotating adjusting column through its elasticity.

[0009] Preferably, the interior of the adjusting column and the water-cooling patch is hollow, and the top of the five-lobed adjusting plate is in contact with the bottom of the adaptive lobes. This design allows the coolant to form a stable water channel through the water-cooling tank, adjusting column, arc-shaped hose, and water inlet, circulating the coolant from inside the water-cooling tank to inside the water-cooling patch.

[0010] Preferably, the gun body is provided with a spray-assisted heat dissipation mechanism on its side. This mechanism includes a fixing plate, the side of which is fixedly connected to the side of the gun body. A micro motor is fixedly connected to the side of the fixing plate, and an intermittent compression rod is fixedly connected to the output shaft of the micro motor. A spray bottle is fixedly connected to the bottom of the inner wall of the water-cooling box. A spray pipe extends through the side of the spray bottle, with one end of the spray pipe extending through the side of the water-cooling box. A pressurized arc pipe is fixedly connected to the end of the spray pipe inside the water-cooling box, with one end extending through the bottom of the water-cooling box. A piston block is slidably connected to the other end of the pressurized arc pipe. The spray-assisted heat dissipation mechanism is designed to cooperate with the air-cooling mechanism inside the air-water synchronous heat dissipation device, allowing the cooling water mist sprayed by the spray-assisted heat dissipation mechanism to adhere to the surface of the gun body under the force of the airflow from the air-cooling mechanism, thereby increasing the heat dissipation effect on the gun body surface.

[0011] Preferably, a squeezing rod is fixedly connected to the circumferential surface of the adjusting column, and a start switch is provided on the outer surface of the micro motor. A tension spring is fixedly sleeved on the trigger end of the start switch, and one end of the tension spring is fixedly connected to the outer surface of the micro motor. The trigger end of the start switch is located on the displacement trajectory of the squeezing rod. During the rotation of the adjusting column, the squeezing rod rotates synchronously. After the squeezing rod rotates synchronously, it squeezes the start switch, starting the micro motor to drive the intermittent squeezing rod to rotate, thereby achieving the function of adaptively activating the spray-assisted heat dissipation mechanism, realizing automated design, and facilitating actual operation.

[0012] Preferably, a limiting spring is fixedly connected to the outer surface of the piston block, and one end of the limiting spring is fixedly connected to the end of the pressurized arc tube near the piston block. The function of the limiting spring is mainly to automatically reset the piston block without being squeezed by the intermittent extrusion rod through its own elastic potential energy, so as to achieve the effect of intermittent spraying.

[0013] Preferably, the bottom of the water-cooled box is provided with an air passage protection component. This component includes an adapter gear, one end of which is fixedly connected to the bottom of the water-cooled box. A valve stem shaft is fixedly connected to the top of the adapter gear, one end of which penetrates the bottom of the water-cooled box. A butterfly valve core is fixedly connected to the top of the valve stem shaft, and the top of the butterfly valve core penetrates one end of the pressurized arc tube and is rotatably connected to the inner wall of the pressurized arc tube. The air passage protection component is designed to coordinate with the spray-assisted cooling mechanism and the air-water cooling synchronous cooling device. After the spray-assisted cooling mechanism is activated, the air passage protection component opens in coordination to ensure the stable operation of the spray-assisted cooling mechanism. After the spray-assisted cooling mechanism is closed, the air passage protection component automatically closes, thus ensuring a sealed air passage after the spray-assisted cooling mechanism is closed. This prevents the spray-assisted cooling mechanism from opening during non-working hours due to external forces, avoiding resource waste, and also protects the inside of the pressurized arc tube.

[0014] Preferably, the side of the adapter gear meshes with the side of the pinion, and one end of the valve stem shaft that passes through the water-cooled box is rotatably connected to the bottom of the inner wall of the water-cooled box. The meshing of the sides of the adapter gear and the pinion ensures stable operation of the equipment.

[0015] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0016] 1. This electric vehicle AC charging gun, through the design of a simultaneous air-cooling and water-cooling heat dissipation device, causes the rotating adjustment column to drive the connecting seat to rotate, and the rotating connecting seat to drive the air-cooling box to rotate. When the air-cooling box rotates to one side of the gun body, the air-cooling fan is activated to provide stable air-cooling heat dissipation to the gun body through the heat dissipation vents on the air-cooling box. At the same time, the water-cooling pad is fixedly connected to the connecting seat. When the connecting seat rotates to one side of the gun body, the water-cooling pad contacts the side of the gun body near the output port. The coolant flowing into the water-cooling pad provides stable water-cooling heat dissipation to the side of the gun body near the output port, thereby improving the heat dissipation effect of the gun body.

[0017] 2. This electric vehicle AC charging gun, through the design of a spray-assisted heat dissipation mechanism, causes the pressure inside the spray bottle to rise intermittently, intermittently discharging the coolant inside the spray bottle into the spray pipe in the form of mist, and then discharging it through one end of the spray pipe. The discharged coolant is stably attached to the surface of the charging gun by the wind force of the air-cooling mechanism for heat dissipation. In the high temperature environment of summer, the sprayed mist is quickly absorbed and evaporated after adhering to the high temperature gun surface, which not only improves the heat dissipation effect, but also avoids the risk of water entering the output port.

[0018] 3. The design of the air passage protection component of this electric vehicle AC charging gun ensures that after the spray-assisted cooling mechanism is activated, the air passage protection component opens in coordination to ensure the stable operation of the spray-assisted cooling mechanism. After the spray-assisted cooling mechanism is closed, the air passage protection component automatically closes, thus ensuring that a sealed air passage is formed after the spray-assisted cooling mechanism is closed. This prevents the spray-assisted cooling mechanism from opening during non-working hours due to external forces, thus avoiding resource waste. At the same time, it protects the inside of the pressurized arc tube. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-8 One embodiment of the present invention is: an AC charging gun for electric vehicles, including a gun body 1, an output port 2 provided on the side of the gun body 1, a handle 3 fixedly connected to the side of the gun body 1, and a simultaneous air-cooling and water-cooling heat dissipation device 4 provided on the outer surface of the gun body 1; the simultaneous air-cooling and water-cooling heat dissipation device 4 includes a water-cooling box 41, an adjusting column 42 rotatably connected to the bottom of the water-cooling box 41, a connecting seat 43 fixedly connected to the circumferential surface of the adjusting column 42, and an air-cooling box 44 fixedly connected to the side of the connecting seat 43. A fan 45 is fixedly connected to the inner side of the air-cooled box 44. A heat dissipation vent 416 is opened on the side of the air-cooled box 44. A water-cooling patch 46 is fixedly connected to the bottom of the connector 43. An arc-shaped flexible tube 47 is fixedly connected to the side of the water-cooling patch 46. One end of the arc-shaped flexible tube 47 is fixedly connected to the bottom of the adjusting column 42. A five-lobed adjusting plate 48 is fixedly connected to the top of the inner wall of the adjusting column 42. A water inlet 49 is opened on the top of the water-cooled box 41. An adaptive plate 410 is fixedly connected to one end of the water inlet 49.

[0030] A pinion 411 is fixedly connected to the outer surface of the adjusting column 42, and a locking plate 412 is slidably connected to the bottom of the water-cooled box 41. A locking block 413 is fixedly connected to the side of the locking plate 412. In the initial state, the adjusting column 42 is engaged with the locking block 413. The actual size of the locking block 413 is adapted to the teeth of the pinion 411 to ensure that the rotation angle of the adjusting column 42 is locked at this time. When it is necessary to adjust the rotation angle of the adjusting column 42, the user can pull out the locking plate 412 to drive the locking block 413 to disengage from the pinion 411. After rotating the adjusting column 42 to the appropriate angle, the locking plate 412 is released. The locking block 413 is engaged with the pinion 411 by the elastic potential energy of the return spring 414 and locks the adjusted position. In the normal state, the locking plate 412 can slide to avoid the rotation of the gear.

[0031] A return spring 414 is fixedly connected to the side of the card plate 412. One end of the return spring 414 is fixedly connected to a spring fixing plate 415, and the top of the spring fixing plate 415 is fixedly connected to the bottom of the water-cooled box 41. The return spring 414 is designed to adaptively adjust the rotating adjusting column 42 through its elasticity.

[0032] The interiors of the regulating column 42 and the water-cooling patch 46 are hollow, with the top of the five-lobed regulating fin 48 in contact with the bottom of the adaptive fin 410. This design allows the coolant to form a stable water channel through the water-cooling tank 41, regulating column 42, curved hose 47, and water inlet 49, circulating the coolant from inside the water-cooling tank 41 to inside the water-cooling patch 46.

[0033] Working principle: During the charging process, the charging gun generates a lot of heat due to the conversion of AC power to DC power to charge the battery. Especially when charging at outdoor charging stations in summer, there is a lack of effective heat dissipation components to dissipate the heat, which can easily cause safety hazards.

[0034] In this invention, after the output port 2 is inserted into the car charging port, the user can pull out the card plate 412 to drive the card block 413 to disengage from the small gear 411. At this time, rotating the adjusting column 42 drives the connecting seat 43 to rotate. The rotation of the connecting seat 43 drives the air-cooling box 44 to rotate. When the air-cooling box 44 rotates to the side of the gun body 1, the air-cooling fan 45 is started to provide stable air-cooling heat dissipation to the gun body 1 through the heat dissipation vent 416 opened on the air-cooling box 44. At the same time, the card plate 412 is released, and the card block 413 is engaged with the small gear 411 by the elastic potential energy of the reset spring 414 and locks the adjusted position.

[0035] At this time, rotating the adjusting column 42 drives the five-lobed adjusting plate 48 to rotate. After the five-lobed adjusting plate 48 rotates, it forms an interlaced space with the adaptive lobes 410. The coolant inside the water-cooled box 41 is discharged into the adjusting column 42 through the water inlet 49, and then discharged into the water-cooling patch 46 through the arc-shaped hose 47 connected to the bottom of the adjusting column 42. At the same time, the water-cooling patch 46 is fixedly connected to the connecting seat 43. When the connecting seat 43 rotates to one side of the gun body 1, the water-cooling patch 46 contacts the side of the gun body 1 near the output port 2. The coolant flowing into the water-cooling patch 46 provides stable water cooling heat dissipation to the side of the gun body 1 near the output port 2, thereby improving the heat dissipation effect on the gun body 1.

[0036] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, a spray-assisted heat dissipation mechanism 5 is provided on the side of the gun body 1. The spray-assisted heat dissipation mechanism 5 includes a fixing plate 51, the side of the fixing plate 51 is fixedly connected to the side of the gun body 1, a micro motor 52 is fixedly connected to the side of the fixing plate 51, an intermittent extrusion rod 53 is fixedly connected to the output shaft of the micro motor 52, a spray bottle 54 is fixedly connected to the bottom of the inner wall of the water-cooled box 41, a spray pipe 55 passes through the side of the spray bottle 54, one end of the spray pipe 55 passes through the side of the water-cooled box 41, a pressurized arc pipe 56 is fixedly connected to the end of the spray pipe 55 inside the water-cooled box 41, one end of the pressurized arc pipe 56 passes through the bottom of the water-cooled box 41, and a piston block 57 is slidably connected inside the other end of the pressurized arc pipe 56. The design of the spray-assisted heat dissipation mechanism 5 is mainly to cooperate with the air-cooling heat dissipation mechanism inside the air-water cooling synchronous heat dissipation device 4, so that the cooling water mist sprayed by the spray-assisted heat dissipation mechanism 5 can adhere to the surface of the gun body 1 under the action of the air-cooling heat dissipation mechanism, thereby increasing the heat dissipation effect on the surface of the gun body 1.

[0037] A pressing rod 58 is fixedly connected to the circumferential surface of the adjusting column 42. A start switch 59 is provided on the outer surface of the micro motor 52. A tension spring 510 is fixedly sleeved on the trigger end of the start switch 59. One end of the tension spring 510 is fixedly connected to the outer surface of the micro motor 52. The trigger end of the start switch 59 is located on the displacement trajectory of the pressing rod 58. During the rotation of the adjusting column 42, the pressing rod 58 rotates synchronously. After the pressing rod 58 rotates synchronously, it presses the start switch 59, which starts the micro motor 52 to drive the intermittent pressing rod 53 to rotate, thereby achieving the function of adaptively opening the spray-assisted heat dissipation mechanism 5, realizing automated design, and facilitating actual operation.

[0038] A limiting spring 511 is fixedly connected to the outer surface of the piston block 57. One end of the limiting spring 511 is fixedly connected to the end of the pressurized arc tube 56 near the piston block 57. The function of the limiting spring 511 is mainly to use its own elastic potential energy to automatically reset the piston block 57 without being squeezed by the intermittent extrusion rod 53, so as to achieve the effect of intermittent spraying.

[0039] A gas passage protection component 6 is installed at the bottom of the water-cooled box 41. The gas passage protection component 6 includes an adapter gear 61, one end of which is fixedly connected to the bottom of the water-cooled box 41, and a valve stem shaft 62 is fixedly connected to the top end of the adapter gear 61. One end of the valve stem shaft 62 passes through the bottom of the water-cooled box 41, and a butterfly valve core 63 is fixedly connected to the top end of the valve stem shaft 62. The top end of the butterfly valve core 63 passes through one end of the pressurized arc tube 56 and is rotatably connected to the inner wall of the pressurized arc tube 56. The gas passage protection component 6 is designed to cooperate with the spray-assisted heat dissipation mechanism 5 and the air-water cooling synchronous heat dissipation device 4 to operate synchronously. After the spray-assisted heat dissipation mechanism 5 is started, the gas passage protection component 6 opens in coordination to ensure the stable operation of the spray-assisted heat dissipation mechanism 5. After the spray-assisted heat dissipation mechanism 5 is closed, the gas passage protection component 6 closes automatically, thereby ensuring that a sealed gas passage is formed after the spray-assisted heat dissipation mechanism 5 is closed. This prevents the spray-assisted heat dissipation mechanism 5 from opening during non-working hours due to external forces, thus avoiding resource waste. At the same time, it protects the inside of the pressurized arc tube 56.

[0040] The side of the adapter gear 61 meshes with the side of the pinion 411, and one end of the valve stem shaft 62 that passes through the water-cooled box 41 is rotatably connected to the bottom of the inner wall of the water-cooled box 41. The meshing of the side of the adapter gear 61 with the side of the pinion 411 ensures the stable operation of the equipment.

[0041] Working principle: During the rotation of the adjusting column 42, the squeezing rod 58 rotates synchronously. After the squeezing rod 58 rotates synchronously, it squeezes the start switch 59, and the micro motor 52 starts to drive the intermittent squeezing rod 53 to rotate. The intermittent squeezing rod 53 rotates and intermittently squeezes one end of the piston block 57. One end of the piston block 57 is intermittently squeezed and intermittently slides upward inside the pressurizing arc tube 56, applying pressure to the inside of the pressurizing arc tube 56. The pressure inside the pressurizing arc tube 56 rises intermittently, causing the pressure inside the spray tube 55 to rise intermittently. The intermittent rise in pressure inside the spray tube 55 drives the pressure inside the spray bottle 54 to rise intermittently. The intermittent rise in pressure inside the spray bottle 54 intermittently discharges the coolant inside the spray bottle 54 into the spray tube 55 in the form of mist and discharges it through one end of the spray tube 55. The discharged coolant is stably attached to the surface of the charging gun for heat dissipation under the action of the wind force of the air cooling heat dissipation mechanism. In the high temperature environment of summer, the sprayed mist is quickly absorbed and evaporated after adhering to the high temperature surface of the gun body 1, which improves the heat dissipation effect and avoids the risk of water entering the output port 2.

[0042] When the regulating column 42 rotates to activate the air-water cooling synchronous heat dissipation device 4 and the spray-assisted heat dissipation mechanism 5, the meshing adapter gear 61 rotates synchronously. The synchronous rotation of the adapter gear 61 drives the valve stem shaft 62 to rotate synchronously, which in turn drives the butterfly valve core 63 to rotate synchronously, thereby opening the inside of the pressurized arc pipe 56. When the regulating column 42 rotates to close the air-water cooling synchronous heat dissipation device 4 and the spray-assisted heat dissipation mechanism 5, the meshing adapter gear 61 rotates synchronously. The synchronous rotation of the adapter gear 61 drives the valve stem shaft 62 to rotate synchronously, and the valve stem... The synchronous rotation of shaft 62 drives the butterfly valve core 63 to rotate synchronously, thereby closing the inside of the pressurized arc tube 56. After the spray-assisted heat dissipation mechanism 5 is started, the coordinated air passage protection component 6 opens to ensure the stable operation of the spray-assisted heat dissipation mechanism 5. After the spray-assisted heat dissipation mechanism 5 is closed, the air passage protection component 6 is automatically closed to ensure that a sealed air passage is formed after the spray-assisted heat dissipation mechanism 5 is closed, avoiding the spray-assisted heat dissipation mechanism 5 from opening during non-working hours due to external forces, thus avoiding resource waste. At the same time, it protects the inside of the pressurized arc tube 56.
