Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, and in particular to an integrated interactive device for thermal management of vehicle charging piles, a charging pile and a vehicle-mounted charging device. Background Art

[0002] As the number of electric vehicles continues to increase, the demand for fast-charging battery technology is becoming increasingly urgent. However, due to the two major problems of thermal management of automotive batteries and heat dissipation of charging cables, fast-charging technology for electric vehicles has not been widely used. When charging piles charge electric vehicle batteries quickly, the heat generated by the batteries will increase exponentially compared to ordinary slow charging. For batteries, high-density heat accumulation will accelerate battery aging. Therefore, the problem of battery cooling during fast charging has become the main factor hindering the battery charging speed.

[0003] However, the existing on-board cooling system cannot meet the requirements for battery cooling during fast charging due to its limited heat dissipation capacity during charging. Moreover, in extreme weather, when the battery temperature is too low, the charging speed of the battery will also be affected and reduced. At the same time, when electric vehicles are charged at high power, the heating of the cable is also an issue that cannot be avoided. The general practice is to reduce the heat generation by increasing the cross-sectional area of ​​the conductor, but this method will make the charging cable and charging gun bulky on the one hand, and on the other hand, as the charging time increases, if the heat inside the charging cable cannot be taken out, it will burn the charging cable and charging gun, causing safety hazards. The charging pile end also needs to be equipped with a cooling system. The most commonly used is the air cooling system. Some super charging piles have a liquid cooling system, but the super charging liquid cooling only cools the charging pile and charging gun, and cannot cool the battery. If the battery cooling only relies on the on-board cooling system, it is limited by the heat dissipation power of the vehicle end, and cannot be timely and effective. Heat dissipation cannot be carried out, and it will also increase the energy consumption of the vehicle end. There are related devices that use charging pile thermal management to coordinate the thermal management and temperature maintenance of the entire vehicle, but there is no related technology to interactively connect the charging pile thermal management and the thermal management of the entire vehicle power, and there is no related technology to enable compatible charging of new and old charging guns.

[0004] Therefore, it is necessary to provide an integrated interactive device for vehicle-pile charging thermal management, a charging pile and an on-board charging device to solve the problem that the vehicle-pile thermal management (charging pile cooling system) of new energy vehicles and the power thermal management (on-board thermal management system) of the vehicle end cannot be interconnected.

Therefore, the integrated interactive device of the utility model solves the problem that the vehicle pile thermal management of the new energy vehicle and the power thermal management of the vehicle end cannot be interconnected. Through the corresponding connection of a pair of first circulating water pipes 12 and a pair of second circulating water pipes 23, the vehicle thermal management system and the charging pile cooling system are connected, so that when the vehicle is charged, the charging pile cooling system is used to cool the battery immediately, reduce the energy consumption of the vehicle end, and use the charging pile thermal management to coordinate the power thermal management and temperature maintenance function of the whole vehicle.

[0040] See also Figure 5 , Figure 7 and Figure 8 In one embodiment of the utility model, the connecting seat 1 is arranged at an end of the vehicle-mounted charging socket 5 away from its docking end 51, and the docking end 51 has a plug-in cavity 511 for plugging in the gun head 41 of the charging gun 4, and a pair of cylindrical accommodating cavities 13 for accommodating a pair of first circulating water pipes 12 are opened on the connecting seat 1, and the axial direction of each accommodating cavity is parallel to the axial direction of the vehicle-mounted charging socket 5.

[0041] See also Figure 9 and Figure 10, the locking snap ring 32 includes a pair of sleeves 321 and a toothed plate 322. The axial directions of each sleeve are respectively parallel to the length direction of the toothed plate 322, and the pair of sleeves 321 are symmetrically arranged on both sides of the toothed plate 322 and fixedly connected into one body through the toothed plate 322.

A card slot 123 is provided on the outer side wall of each first circulating water pipe, and a buckling portion 241 that cooperates with the card slot 123 is provided at one end of each card 24 away from the moving seat 22. When the locking snap ring 32 moves outside the pair of first circulating water pipes 12 and clamps each card 24, the buckling portion 241 of each card 24 is clamped on the corresponding card slot 123. The moving seat 22 is slidably fitted on the outer side wall of the charging gun 4, and a convex mounting portion 222 is formed on one side of the moving seat 22 away from the charging gun 4.

[0042] Please refer to Figure 12 and Figure 13 , the locking motor mechanism 31 is installed in the installation cavity Ⅰ2221 inside the mounting portion 222. The locking motor mechanism 31 includes a locking motor 311 and a bevel gear transmission mechanism Ⅰ312. The bevel gear transmission mechanism Ⅰ312 meshes with the teeth of the toothed plate 322, so that the locking motor 311 is driven through the bevel gear transmission mechanism Ⅰ312, and the sleeve moves along the axial direction of the pair of second circulating water pipes 23.

[0043] Among them, the bevel gear transmission mechanism Ⅰ312 includes a pair of meshing bevel gears Ⅱ, a transmission gear Ⅱ3122 and a spur gear Ⅱ3123. The pair of bevel gears Ⅱ are respectively the first bevel gear Ⅱ3121 and the second bevel gear Ⅱ3121'. The first bevel gear Ⅱ3121 is installed on the output shaft of the locking motor 311. The second bevel gear Ⅱ3121' meshes with the first bevel gear Ⅱ3121 and is installed in the installation cavity Ⅰ2221 through a shaft perpendicular to the output shaft of the locking motor 311. The transmission gear Ⅱ3122 is installed on the shaft of the second bevel gear Ⅱ3121'. The spur gear Ⅱ3123 meshes with the transmission gear Ⅱ3122 and is installed in the installation cavity Ⅰ2221 through a shaft perpendicular to the output shaft of the locking motor 311. The spur gear Ⅱ3123 also keeps meshing with the teeth of the toothed plate 322. Therefore, when the locking motor 311 works, it drives the toothed plate 322 to move in a straight line along the direction perpendicular to the output shaft of the locking motor 311, thereby driving the pair of sleeves 321 to move along the axial direction of the pair of second circulating water pipes 23.

[0044] Please refer to Figure 11 and Figure 5, in an embodiment of the present utility model, the installation surface Ⅰ221 of the moving seat 22 that cooperates with the charging gun 4 is an arc surface, and its axial direction is parallel to the axial directions of a pair of second circulating water pipes 23. A rack 2211 is uniformly arranged along the axial direction in the middle of the installation surface Ⅰ221. On the installation surface Ⅰ221 on both sides of the rack 2211, sliders 2212 are arranged parallel to its axial direction. A sliding groove 411 is axially opened on the corresponding installation surface Ⅱ40 of the charging gun 4. The sliders 2212 are slidably arranged in the corresponding sliding grooves 411, so that the moving seat 22 is slidably installed on the charging gun 4; on the outer cylindrical surface of the charging gun 4 away from the connecting seat 1, a convex ring 42 is coaxially arranged. At one end of the convex ring 42 away from its gun head 41, a pair of limiting surfaces Ⅱ421 are arranged corresponding to the moving seat 22. On the radial two sides of the installation surface Ⅰ221 of the moving seat 22, a pair of limiting surfaces Ⅰ2213 are arranged. The limiting surface Ⅱ and the limiting surface Ⅰ are correspondingly attached to circumferentially limit the moving seat 22.

[0045] Please refer to Figure 5 and Figure 6 , in an embodiment of the present utility model, an installation cavity Ⅱ412 is opened at one end of the charging gun 4 away from the gun head 41. The motor mechanism 21 is arranged in the installation cavity Ⅱ412. The motor mechanism 21 includes a motor 211 and a bevel gear transmission mechanism Ⅱ212. The bevel gear transmission mechanism Ⅱ212 meshes with the rack 2211 on the installation surface Ⅰ221, so that the motor 211 drives the moving seat 22 through the bevel gear transmission mechanism Ⅱ212, thereby enabling the moving seat 22 to drive a pair of second circulating water pipes 23 close to the connecting seat 1 and realizing the butt joint and connection of a pair of second circulating water pipes 23 and a pair of first circulating water pipes 12.

[0046] Among them, the bevel gear transmission mechanism Ⅱ212 includes a pair of meshing bevel gears Ⅱ and 4 spur gears 2122, and the 4 spur gears 2122 are sequentially meshed. The pair of bevel gears Ⅱ are respectively a first bevel gear Ⅱ2121 and a second bevel gear Ⅱ2121'. The first bevel gear Ⅱ2121 is installed on the output shaft of the motor 211. The second bevel gear Ⅱ2121' is in tooth meshing with the first bevel gear Ⅱ2121 and is installed in the installation cavity Ⅱ412 through a shaft perpendicular to the output shaft of the motor 211. A transmission gear Ⅰ2123 is installed on the shaft of the second bevel gear Ⅱ2121'. The transmission gear Ⅰ2123 is in tooth meshing with the corresponding spur gear 2122, and the 4 spur gears 2122 are sequentially meshed. The shafts of the 4 spur gears 2122 are all perpendicular to the output shaft of the motor 211, and are arranged parallel to each other and installed in the installation cavity Ⅱ412. The tooth surfaces of two spur gears 2122 are meshed with the rack 2211 on the installation surface Ⅰ221. Therefore, when the motor 211 works, it drives the rack 2211 to do a linear motion along the direction parallel to the output shaft of the motor 211, that is, the moving seat 22 does a linear motion along the axial direction of the charging gun 4.

[0047] In one embodiment of the present utility model, a connection flange 52 is provided on the periphery of the vehicle-mounted charging socket 5 near its docking end 51. An avoidance opening is formed on one side of the connection flange 52 corresponding to the connection seat 1. The connection seat 1 is fixedly installed on the vehicle-mounted charging socket 5. The vehicle-mounted charging socket 5 is installed on the vehicle end through the connection flange 52. When the moving seat 22 passes through the avoidance opening of the connection flange 52, further radial limitation of the moving seat 22 is achieved. Resistance signal generators are respectively provided on the charging pile and the vehicle end. The resistance signal emitted by the vehicle end is used to determine whether the charging gun 4 is inserted into the charging socket 5, and the resistance signal emitted by the charging pile end is used to identify whether the vehicle end supports the integrated interaction device.

[0048] In one embodiment of the present utility model, a charging pile includes a charging gun and a pile-end generator connected to each other. The charging gun includes a connection mechanism 2. The connection mechanism 2 includes a motor mechanism 21, a moving seat 22, and a pair of second circulating water pipes 23. The pair of second circulating water pipes 23 are inserted into the moving seat 22. The motor mechanism 21 drives the moving seat 22 to move the pair of second circulating water pipes 23 along the axial direction of the charging gun 4. The first end 231 of each second circulating water pipe is correspondingly connected to the corresponding water pipe of the charging pile cooling system, and the second end 231 of each second circulating water pipe opposite to the first end 231 is connected to the corresponding water pipe of the vehicle-mounted thermal management system. The resistance signal emitted by the pile-end generator is used to identify whether the vehicle end supports the connection of the pair of second circulating water pipes 23 and the corresponding water pipes of the vehicle-mounted thermal management system.

[0049] In one embodiment of the present utility model, a vehicle-mounted charging device is provided, which includes a connection seat 1 and a vehicle-mounted charging socket 5. The connection seat 1 is arranged at one end of the vehicle-mounted charging socket 5 away from its docking end 51. The docking end 51 has a plugging cavity 511 for the gun head 41 of the charging gun 4 to be plugged in. The connection seat 1 includes a seat body 11 and a pair of first circulating water pipes 12. A pair of cylindrical accommodating cavities 13 for accommodating the pair of first circulating water pipes 12 are formed on the connection seat 1, and the axial direction of each accommodating cavity is parallel to the axial direction of the vehicle-mounted charging socket 5. The first end 121 of each first circulating water pipe is connected to the corresponding water pipe of the vehicle-mounted thermal management system, and the second end 122 of each first circulating water pipe opposite to the first end 121 is connected to the corresponding water pipe of the charging pile cooling system.

[0050] The thermal management interaction connection process between the charging gun 4 and the vehicle-mounted charging socket 5 of the present utility model includes:

[0051] a. The connection seat 1 is arranged at one end of the vehicle-mounted charging socket 5 away from its docking end 51. After the gun head 41 of the charging gun 4 is plugged into the plugging cavity 511 of the docking end 51, the original mechanical locking mechanism of the charging gun 4 is locked to prevent the charging gun 4 from being pulled out.

[0052] b. The charging pile and the vehicle end are respectively provided with generators for emitting resistance signals. The resistance signal emitted by the vehicle end is used to determine whether the charging gun is inserted into the on-vehicle charging socket 5, and the resistance signal emitted by the charging pile end is used to identify whether the vehicle end supports the integrated interaction device, that is, whether it supports the vehicle-pile thermal management function;

[0053] c. When the charging pile recognizes that the vehicle end is an old on-vehicle charging socket 5 that does not support the vehicle-pile thermal management function, the connecting mechanism 2 at the gun end will not move and only remains in the initial position. At this time, the vehicle only performs the charging function and does not perform vehicle-pile thermal management interaction. Therefore, it can be compatible with vehicles without the vehicle-pile thermal management function in the past; when the charging pile recognizes that the vehicle end is a new on-vehicle charging socket 5 that supports the vehicle-pile thermal management function, the motor 211 drives the moving seat 22 to move towards the on-vehicle charging socket 5, and drives the first end 231 of each retractable second circulation water pipe to move towards the first end 121 of the first circulation water pipe;

[0054] d. When the first end 231 of the second circulation water pipe and the first end 121 of the first circulation water pipe are correspondingly connected, the card 24 will also reach the locking position, and the locking motor 311 will drive the locking snap ring 32 to lock, and a pair of first circulation water pipes 12 and a pair of second circulation water pipes 23 are connected and locked;

[0055] f.
