Description

Technical Field

[0001] This invention relates to the field of automotive battery charger technology, and in particular to an intelligent automotive battery charger. Background Technology

[0002] The widespread adoption of electric vehicles has led to the extensive deployment of charging infrastructure. Traditional charging stations only have basic charging capabilities, and cable management relies on manual dragging. Cables exposed for extended periods are prone to accumulating mud and water, and are easily tangled and damaged during dragging, posing a potential electrical hazard. The equipment relies solely on simple ventilation and heat dissipation, lacking a corresponding airflow dust removal structure, making it prone to poor contact at cable conductive joints. The internal wiring layout is simple and difficult to adapt to automatic cable rewinding and unwinding structures, resulting in low overall automation and frequent malfunctions during long-term outdoor use.

[0003] Existing traditional charging piles lack an integrated linkage drive structure. Dust easily accumulates inside the charging gun storage shell, and dirty contacts can cause safety issues such as overheating and sparking. Meanwhile, the cover needs to be opened manually, and users can only wipe it manually, resulting in poor cleaning effect and risk of electric shock. The device can only complete charging and lacks supporting auxiliary functions, making its overall practicality poor.

[0004] Conventional charging piles do not integrate automatic cleaning and dust collection components, making it difficult to remove fine dust from the gaps in the charging head by manual wiping. Dust accumulation during cleaning will accelerate the aging of the electronic control system and motor. Traditional cable winding mechanisms can only wind up and wind up cables, making it difficult to clean impurities on the cable surface at the same time. The equipment control logic is simple, and it is difficult for the various power components to work in sync. Cable winding, door opening, and cleaning need to be done in separate steps, making the operation process cumbersome and resulting in a poor user experience. Summary of the Invention

[0005] The technical problem to be solved by this invention is to provide an intelligent car battery charger, in order to solve the technical problems of existing traditional charging piles, such as low level of automation, easy damage and leakage of cables due to manual dragging, lack of cable dust removal structure, no linkage drive of equipment, manual opening of cover plate, dust accumulation on gun head which easily causes safety hazards, lack of automatic dust collection and cleaning device, incomplete manual cleaning, inability of various processes to be linked synchronously, cumbersome operation, and easy aging and failure of equipment.

One end of the grooved roller is fitted with a funnel-shaped protective cover through a sealing gasket. The other end of the funnel-shaped protective cover is installed on the inner wall of one side of the charging pile housing. The other end of the grooved roller is installed on one side of the conductive slip ring pin. A second circular base is installed on the inner wall of one side of the charging pile housing. Multiple sets of cooling fans are installed on the other end of the second circular base. A first motor is installed on the inner wall of one side of the charging pile housing. The other end of the rotating shaft is installed at the output end of the first motor.

[0010] Optionally, the drive assembly includes a charging gun protective shell, which is installed on the front outer wall of the charging pile housing. A gear protective shell is installed on the bottom outer wall of the charging gun protective shell, and a second motor is installed on one inner wall of the charging gun protective shell.

[0011] Optionally, a first gear is installed at the output end of the second motor, and a second gear is synchronously installed at the output end of the second motor via a rotating shaft. A third gear is meshed with one side of the second gear, and a door hinge is installed at the center of the top of the third gear.

[0012] Optionally, the two ends of the door hinge are installed on the front outer wall of the charging gun protective shell, a fourth gear is meshed with one side of the first gear, the bottom of the fourth gear is rotatably connected to the bottom inner wall of the charging gun protective shell through a bearing, and a fifth gear is meshed with one side of the fourth gear.

[0014] Optionally, the cleaning assembly includes a slide rod mounted on the inner bottom wall of the charging gun protective shell, a third base sleeved on the outer surface of the slide rod, one set of the third bases being threadedly connected to the outer surface of the threaded rod, a cleaning box being mounted on the top of the third base, and a third motor being mounted on the inner bottom wall of the cleaning box.

[0015] Optionally, a sixth gear is installed at the output end of the third motor, a gear plate is meshed with one side of the sixth gear, two sets of brushes are installed on the top of the gear plate, a hollow bearing is installed on the inner wall of the bottom of the cleaning box, an air suction hood is installed on the inner wall of the hollow bearing, an air suction pump is installed on the inner wall of the air suction hood, and the air suction pump is installed on the inner wall of the bottom of the cleaning box.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: The above solution, by storing the charging gun downwards within the protective shell, differs from the traditional top-mounted, horizontally exposed layout. This offers significant advantages for outdoor use, solving the problem of rainwater accumulating in the connector cavity when the gun head is facing upwards, causing pin corrosion, poor contact, and the potential for overheating and sparking due to mud and sand accumulation. This solution relies on gravity to allow accumulated water and dirt to drip naturally, preventing them from remaining in the gun head gaps. This significantly reduces the entry of mud, leaves, and insects into the connector, avoiding connector failure caused by foreign objects. This structure eliminates the need for additional rainproof baffles, thickened sealing rings, and other accessories, simplifying the overall structure and reducing maintenance costs associated with replacing aging waterproof components. Long-term outdoor use reduces the probability of corrosion of conductive components, extends the charging gun's lifespan, reduces equipment malfunctions and repairs, and improves the stability of all-weather charging operation. It is suitable for various complex outdoor charging scenarios such as residential areas, highways, and parking lots.

[0017] By using two sets of motors working in sync, the cable retraction and extension, the opening and closing of the charging gun protective cover, and the lifting and lowering of the cleaning mechanism are controlled separately. A single button can trigger the entire set of synchronized actions, solving the drawbacks of traditional equipment that requires step-by-step operation, manual opening and closing of the cover, and manual dragging of the cable. Traditional charging pile covers need to be manually pushed and pulled, and the cable relies entirely on manual pulling, which is prone to tangling and damage, resulting in low operating efficiency in high-frequency use scenarios. After pressing the start button, this device has two motors running synchronously, the cover automatically opens, the cleaning component descends synchronously, and the cable is released at a uniform speed, eliminating the need for manual step-by-step operation. After charging is completed, the device runs in reverse synchronously, automatically retracting the cable, raising the cleaning component, and closing the cover, thus improving the service life of the charging gun.

[0018] By integrating a single cleaning component, the charging gun automatically cleans its head after being returned to its protective casing, pre-cleaning it for the next charge and overcoming the shortcoming of traditional charging piles lacking automatic cleaning functions. This solves the problem of traditional equipment relying solely on manual wiping, which is difficult to remove dust and metal debris from crevices, leading to increased contact resistance, overheating, and contact erosion. Furthermore, wiping dust can contaminate internal electrical controls and motors, accelerating equipment aging. This cleaning component uses a rotating brush to thoroughly clean impurities from the gun head crevices, while negative pressure suction simultaneously collects dust, preventing it from spreading into the equipment and contaminating other components. Cleaning is automatically performed each time the gun is returned to its original position, requiring no manual intervention. This ensures clean contacts every time the gun head is used, stably controls contact resistance, reduces the risk of charging fires and short circuits, and improves charging safety. Continuous cleaning slows down the oxidation of metal contacts, extends the charging gun's lifespan, reduces the manpower required for manual inspections and maintenance, lowers long-term site maintenance costs, and achieves autonomous equipment cleaning.

Detailed Implementation

[0021] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0022] like Figures 1 to 12As shown, an embodiment of the present invention provides a smart charger for an automotive battery, including a charging pile device 1, a charging pile housing 10 installed on the outside of the charging pile device 1, a switch button 11 installed on the front outer wall of the charging pile housing 10, a ventilation opening 12 installed on one side of the charging pile housing 10, a support rod 13 installed on the inner wall of one side of the charging pile housing 10, an electrical box 14 sleeved on the outer surface of the support rod 13, an electrical box 15 installed on the inner wall of the bottom of the charging pile housing 10, a cable 16 installed on the outer wall of one side of the electrical box 15, a cable reel assembly 2 installed on the inner wall of one side of the charging pile housing 10, a drive assembly 3 installed on the outer wall of one side of the charging pile housing 10, and a cleaning assembly 4 installed on the inner wall of the bottom of the charging gun protective shell 30. The charging pile housing 10 is integrally molded. The internal structure features multiple partition ribs that separate the installation areas of the electrical box 15, the cable reel assembly 2, and the drive assembly 3, preventing components from colliding during operation. The support rod 13 is a metal square rod structure, welded to the inner wall of the housing at multiple points. The wiring box 14 is attached to the surface of the support rod 13 via a snap-fit, allowing for direct disassembly and convenient maintenance and replacement of internal control lines. A dust filter is installed inside the ventilation vent 12 to block large outdoor dust particles from entering the housing. The filter is removable, and regular cleaning is sufficient to maintain heat dissipation. The electrical box 15 has an independent isolation compartment, with high-voltage charging lines and low-voltage control lines arranged separately to effectively reduce electromagnetic interference. The switch button 11 has a built-in waterproof silicone gasket to prevent moisture infiltration and short-circuit faults during outdoor use.

[0023] like Figures 3 to 5As shown, the cable retraction assembly 2 includes a first circular base 20. One end of the first circular base 20 is installed on the inner wall of one side of the charging pile housing 10. A carbon brush conductive slip ring 21 is installed on the other end of the first circular base 20. A cable 16 is connected to the input end of the carbon brush conductive slip ring 21, and a conductive slip ring pin 210 is installed on the output end of the carbon brush conductive slip ring 21. A copper wire 22 is connected to one side of the conductive slip ring pin 210. A rotating shaft 23 is sleeved on one side of the inner wall of one side of the charging pile housing 10 through a bearing. A grooved roller 24 is sleeved on the outer surface of the middle part of the rotating shaft 23 through two sets of bearings. Multiple sets of holes 240 are opened at the bottom of the spiral groove of the grooved roller 24. Multiple sets of holes 240 are opened at one end of the grooved roller 24. A funnel-shaped protective cover 25 is installed on one end of the grooved roller 24 through a sealing gasket. The other end of the funnel-shaped protective cover 25 is installed on the inner wall of one side of the charging pile housing 10. The other end of the grooved roller 24 is installed on... On one side of the conductive slip ring pin 210, a second circular base 26 is installed on the inner wall of one side of the charging pile housing 10. Multiple cooling fans 27 are installed on the other end of the second circular base 26. A first motor 28 is installed on the inner wall of one side of the charging pile housing 10, and the other end of the rotating shaft 23 is installed at the output end of the first motor 28. Both the first circular base 20 and the second circular base 26 are locked with flange bolts. Disassembly and assembly do not require disassembly of the main body of the charging pile housing 10, which facilitates separate maintenance of the carbon brush conductive slip ring 21 and the cooling fan 27. An annular sealing gasket is added to the inside of the funnel-shaped protective cover 25 to completely seal the gap at the end of the grooved roller 24. The holes 240 are evenly distributed along the spiral groove, and the cooling fan 27 completes the air cooling and heat absorption. Wear-resistant bearings are matched at both ends of the rotating shaft 23. Long-term reciprocating rotation is not prone to gaps, which can prevent the grooved roller 24 from shifting and causing the copper wires 22 to stack and get stuck, thus improving the smoothness of cable winding and unwinding.

[0024] like Figures 6 to 9As shown, the drive assembly 3 includes a charging gun protective shell 30, which is installed on the front outer wall of the charging pile housing 10. A gear protective shell 301 is installed on the bottom outer wall of the charging gun protective shell 30. A second motor 31 is installed on one inner wall of the charging gun protective shell 30. A first gear 32 is installed at the output end of the second motor 31. A second gear 33 is synchronously installed at the output end of the second motor 31 via a rotating shaft. A third gear 34 is meshed with one side of the second gear 33. A door hinge 35 is installed at the center of the top of the third gear 34. Both ends of the door hinge 35 are installed on the front outer wall of the charging gun protective shell 30. A fourth gear 36 is meshed with one side of the first gear 32. The bottom of the fourth gear 36 is rotatably connected to the bottom inner wall of the charging gun protective shell 30 via a bearing. A fifth gear 37 is meshed with one side of the fourth gear 36. The gear is rotatably connected to the bottom inner wall of the charging gun protective shell 30 via a bearing. A threaded rod 370 is installed at the top center of the fifth gear 37. A circular groove 38 is opened on the inner wall of the rear end of the charging gun protective shell 30. Multiple sets of rolling balls 380 are installed on the inner wall of the circular groove 38. A bracket 39 is installed on the inner wall of the rear end of the charging gun protective shell 30. The gear protective shell 301 completely covers all meshing gears, isolating them from dust and moisture generated during charging, and preventing gear corrosion and jamming. The rolling balls 380 inside the circular groove 38 are evenly arranged in a ring, reducing wear on the charging gun input cable from all directions. The bracket 39 is made of bent steel plate in one piece, providing limit support for the charging gun. Buffer rubber pads are added to both ends of the door hinge 35 to buffer the impact when the cover is opened and closed, reducing metal collision noise, and preventing deformation and jamming of the door hinge 35 due to long-term impact, thus extending the service life of the entire transmission mechanism.

[0025] like Figures 10 to 12As shown, the cleaning component 4 includes a slide rod 40, which is installed on the inner bottom wall of the charging gun protective shell 30. A third base 41 is sleeved on the outer surface of the slide rod 40. One set of the third base 41 is threadedly connected to the outer surface of the threaded rod 370. A cleaning box 42 is installed on the top of the third base 41. A third motor 43 is installed on the inner bottom wall of the cleaning box 42. A sixth gear 44 is installed at the output end of the third motor 43. A gear plate 45 is meshed on one side of the sixth gear 44. Two sets of brushes 46 are installed on the top of the gear plate 45. A hollow bearing 47 is installed on the inner bottom wall of the cleaning box 42. An air suction hood 48 is installed on the inner wall of the hollow bearing 47. An air suction pump 49 is installed on the inner wall of the air suction hood 48. 9 is installed on the bottom inner wall of the cleaning box 42; the surface of the slide bar 40 is polished and wear-resistant, the third base 41 is clearance-fitted with the slide bar 40, and the lifting and moving is smooth without jamming or obvious shaking. The cleaning box 42 is equipped with an independent dust collection chamber. The dust swept by the brush 46 is sucked into the chamber through the suction hood 48. The dust collection chamber can be pulled out and the dust can be emptied separately. The hollow bearing 47 is interference-fitted with the suction hood 48, which is airtight and ensures the stable negative pressure dust collection effect of the suction pump 49. The third motor 43 is equipped with a shock-absorbing pad on the outside, so that the vibration of the operation will not be transmitted to the charging gun protective shell 30, and avoid the vibration causing the charging gun contacts to loosen. The entire cleaning structure can be disassembled and assembled independently, and the brush 46 and the suction pump 49 can be maintained and replaced separately without disassembling the drive components.

[0026] The working principle of the technical solution provided by this invention is as follows: First, the operator presses the switch button 11, and the charging pile device 1 is powered on. The internal electrical box 15 of the charging pile shell 10 outputs control power, and the ventilation vent 12 continuously convects to dissipate heat, ensuring that the internal components operate at a stable temperature.

[0027] After the equipment is powered on, the first motor 28 and the second motor 31 start synchronously, and the two power mechanisms operate synchronously. At this time, the take-up and undo assembly 2 performs the undoing process synchronously. The first circular base 20 inside the take-up and undo assembly 2 fixes the carbon brush conductive slip ring 21. The carbon brush conductive slip ring 21 is connected to the copper wire 22 by the conductive slip ring pin 210. The copper wire 22 is connected to the cable 16 to realize the conduction of charging power.

[0028] The first motor 28 is connected to the rotating shaft 23 at its output end. The rotating shaft 23 drives the grooved roller 24 to rotate synchronously. The grooved roller 24 rotates and releases the copper wire 22. The holes 240 opened in the grooved roller 24 allow airflow to pass through. The funnel-shaped protective cover 25 blocks impurities at the end of the roller.

[0029] Meanwhile, the second circular base 26 is equipped with a cooling fan 27. The cooling fan 27 generates airflow that passes through the hole 240 to absorb the heat inside the grooved roller 24 and discharge it to the charging pile shell 10. The cable 16 and copper wire 22 are dedicated charging cables for the charging gun and are only used to transmit charging power. The power supply for the whole machine is supplied by an independent line from the electrical box 15 and is isolated from the circuit of the cable 16.

[0030] Subsequently, the second motor 31, which starts synchronously, serves as the power source for the drive component 3. The gear protective shell 301 encloses all the transmission gears. The output end of the second motor 31 synchronously drives the first gear 32 and the second gear 33 to rotate. The second gear 33 meshes with the third gear 34, and the third gear 34 drives the door hinge 35 to rotate. The rotation of the door hinge 35 completely opens the cover of the charging gun protective shell 30.

[0031] The first gear 32 meshes with the fourth gear 36, the fourth gear 36 is linked with the fifth gear 37, the upper end of the fifth gear 37 is fixed with a threaded rod 370, the rolling ball 380 in the circular groove 38 reduces the friction of the charging gun input end wire assembly, the bracket 39 limits the position of the charging gun, the threaded rod 370 rotates and drives the third base 41 to slide down along the slide bar 40, the third base 41 carries the cleaning box 42 and moves down synchronously, the drive assembly 3 and the cleaning assembly 4 descend to the charging parking position corresponding to the charging gun.

[0032] Meanwhile, the first motor 28 continuously drives the grooved roller 24 to feed the wire at a uniform speed, the copper wire 22 is continuously fed out, the carbon brush conductive slip ring 21, the conductive slip ring pin 210, and the copper wire 22 continuously conduct charging power to the cable 16, the cooling fan 27 continuously absorbs the heat inside the grooved roller 24 and discharges it to the charging pile shell 10, and the funnel-shaped protective cover 25 prevents dust from entering the grooved roller 24.

[0033] Then, after the cleaning box 42 descends to its final position, the charging gun can be taken out to charge the vehicle. Once the vehicle is fully charged, the operator presses the switch button 11 again to switch the working mode (the switch button 11 has a built-in circuit board for connecting to the control center and controlling the operation of various electronic devices). At this time, the second motor 31 rotates in reverse, the gears mesh in reverse, the door hinge 35 rotates to close the charging gun protective shell 30 cover, the threaded rod 370 rotates in reverse to pull the third base 41 upward along the slide rod 40 to reset, and the cleaning box 42 is raised synchronously; the first motor 28 rotates synchronously in reverse, driving the rotating shaft 2 3. The grooved roller 24 rotates in the opposite direction, and the grooved roller 24 retracts and winds the copper wire 22 layer by layer. The cooling fan 27 continuously draws air, and the airflow cleans the dust remaining on the surface of the cable 16 during the recycling process through the hole 240. The funnel-shaped protective cover 25 blocks the dust raised by the recycled cable. After the copper wire 22 is completely recycled and stored in the grooved roller 24, the first motor 28 and the cooling fan 27 are powered off and stopped. The carbon brush conductive slip ring 21, the conductive slip ring pin 210, and the copper wire 22 cut off the charging power transmission. The wire box 14 and the support rod 13 maintain the neatness of the internal control circuit, and the ventilation port 12 dissipates the residual heat of the equipment.

[0034] Finally, after the cleaning box 42 descends into place, the cleaning component 4 starts working. The third motor 43 at the bottom of the cleaning box 42 outputs torque to drive the sixth gear 44 to rotate. The sixth gear 44 meshes with the gear plate 45 to rotate, and the brush 46 mounted on the gear plate 45 rotates around the charging gun head to wipe it back and forth.

[0035] At this time, the hollow bearing 47 inside the cleaning box 42 fixes the suction hood 48, and the suction pump 49 is turned on simultaneously. The suction pump 49 collects the dust swept off by the brush 46 through the suction hood 48. The dust is uniformly collected inside the cavity of the cleaning box 42. The entire gear transmission mechanism continuously meshes to keep the cleaning component 4 in a stable position. When the cleaning component 4 has finished cleaning, the electrical box 15 cuts off the power supply to the whole machine, and all components of the charging pile device 1 return to the initial standby position, waiting for the next start signal triggered by the switch button 11. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
