Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] Independently set up charging stations and battery swap stations have technical problems such as reduced charging efficiency and increased risk of battery damage due to voltage fluctuations.

[0039] In view of this, the utility model provides a charging and battery replacement integrated charging pile, comprising:

[0040] The housing 100, the battery exchange unit 200 and the charging unit 300 are both mounted on the housing 100. The battery exchange unit 200 includes a rotating frame 210, which is rotatably connected to the housing 100. The rotating frame 210 is provided with a plurality of receiving slots 201, and the receiving slots 201 are used to load the battery 001. The battery 001 is electrically connected to the charging unit 300.

[0041] Based on the above technical solutions, the integrated charging and battery replacement charging pile provided by the utility model can achieve the following technical effects:

[0042] The integrated charging and swapping charging pile is provided with a connected battery swapping unit 200 and a charging unit 300, and stores electric energy through the loaded battery 001 when the power grid is stable, and switches the working state of the battery 001 when the power grid power supply is abnormal or fluctuates, thereby providing electric energy for the charging unit 300 to ensure stable power supply for electric vehicles. The technical problem that the charging efficiency is reduced due to voltage fluctuations and the risk of battery 001 damage is increased in independently set charging stations is overcome.

[0043] The following combination Figures 1 to 6 The structure and shape of the integrated charging and battery replacement charging pile provided in this embodiment are described in detail:

[0044] In order to store the replaced old batteries, in the scheme of this embodiment, the shell 100 includes a shell 110 and a cover 120. The shell 110 is provided with an operating port 101 for taking and placing the battery 001. The cover 120 is movably connected to the shell 110 to open and close the operating port 101. A receiving slot 201 is used as a temporary storage slot for loading the replaced battery 001. The replaced battery 001 is inserted into the temporary storage slot through the operating port 101, and the fully charged battery 001 is taken out through the operating port 101. At this time, the empty receiving slot 201 is changed to a temporary storage slot. Among them, the cover 120 can be set as a flip cover, a sliding cover, a rotating cover, etc., and the movable connection method with the shell 110 can be correspondingly set to a hinged connection, a sliding connection, a rotating connection, etc.

[0045] Regarding the structural composition of the charging unit 300, specifically:

[0046] The charging unit 300 includes a center rod 310, a motor, a charging cable 320, a charging gun 330 and a power sensor. The center rod 310 is inserted into the housing 100, and a plurality of receiving slots 201 are evenly distributed around the axis of the center rod 310. The motor is installed on the housing 100 and is connected to the rotating frame 210 for driving the rotating frame 210 to rotate around the center rod 310. The center rod 310 is provided with a gun hanging seat, and the charging gun 330 is installed on the gun hanging seat. One end of the charging cable 320 is connected to the charging gun 330, and the other end is connected to the power supply. The power sensor is installed on the rotating frame 210 for detecting the power of each battery 001.

[0047] In the solution of this embodiment, the power exchange unit 200 also includes a power supply ring group 220, which includes a first conductive ring 221 and a second conductive ring 222. The first conductive ring 221 is installed on the center rod 310, and the second conductive ring 222 is installed on the rotating frame 210 and is electrically connected to the first conductive ring 221.

[0048] Specifically, the first conductive ring 221 includes a synchronization ring 2211 and a contact 2212, and the synchronization ring 2211 and the contact 2212 are both electrically connected to the second conductive ring 222. The synchronization ring 2211 and the contact 2212 are not conductive; the second conductive ring 222 includes a plurality of connection segments 2221, each connection segment 2221 is not conductive and is respectively conductive to a receiving slot 201. The contact 2212 is electrically connected to the charging unit 300. The receiving slot 201 of the connection contact 2212 is a battery exchange slot, and the battery 001 in the battery exchange slot is a load battery. The load battery can switch between a charging state and a discharging state. In the discharging state, the load battery supplies power to the charging unit 300.

[0049] In order to reduce the impact of the battery exchange service on the battery exchange service provided by the battery exchange unit 200 to the charging unit 300, in the solution of this embodiment, the battery 001 with the lowest power is used as the load battery, and other batteries 001 continue to be charged to maximize the number of fully charged batteries 001. Specifically, the power level of each battery 001 is measured by a power sensor, and the motor drives the rotating frame to rotate 210 so that the receiving slot 201 of the battery 001 with the lowest power is connected to the contact 2212 as a battery exchange slot. At this time, the battery 001 with the lowest power is the load battery. When the load battery is exhausted, the motor drives the rotating frame 210 to rotate to change the load battery;

[0050] In order to realize the state switching of the load battery, in the scheme of this embodiment, the power exchange unit 200 also includes a conversion switch 230. The conversion switch 230 is used to switch the charging and discharging states of the load battery. In the charging state, one end of the conversion switch 230 is connected to the contact 2212, and the other end is connected to the power supply. In the discharging state, one end of the conversion switch 230 is connected to the contact 2212, and the other end is connected to the charging cable 320. One end of the conversion switch 230 is connected to the first conductive ring 221, and the other end is connected to the power supply and the charging cable 320. Specifically, when the load battery is in the charging state, the conversion switch 230 is connected to the power supply, and the load battery is connected to the power supply through the contact 2212 and the conversion switch 230 in turn for charging. When the load battery is in the discharging state, the conversion switch 230 is connected to the charging cable 320, and the load battery supplies power to the charging gun 330 through the contact 2212, the conversion switch 230 and the charging cable 320 in turn.

[0051] When the load battery is in the charging state, the charging unit 300 relies on the power grid for real-time power supply. When the grid voltage fluctuates due to uneven load and instantaneous load changes, the instability of voltage and current will cause the charging power of the charging unit 300 to be insufficient or unstable, which will directly affect the battery in the charging process. At this time, the conversion switch 230 triggers the load battery to switch from the charging state to the discharging state to power the charging unit 300 so that the charging power of the charging unit 300 is stable to avoid damaging the battery 001.

[0052] In order to improve the interaction efficiency with the user, in the solution of this embodiment, the charging unit 300 further includes an interaction interface 340. The interaction interface 340 is installed on the central rod 310 and can display the power level of each battery 001 and the power supply status of the power source.

[0053] In the solution of this embodiment, the charging unit 300 further includes a cable drum 350 and an electric slip ring. The cable drum 350 is installed on the housing 100. The charging cable 320 is connected to the cable drum 350 through the electric slip ring, and a coil spring is provided at the axis of the cable drum 350, and the elastic force of the coil spring is used to drive the cable drum 350 to rotate to reel the charging cable 320.

[0054] In summary, the specific working process of the integrated charging and battery replacement charging pile provided in this embodiment is as follows:

[0055] In specific applications, during the process of using the battery replacement service for electric vehicles, the interactive interface 340 is operated, and the motor drives the rotating frame 210 to rotate so that the temporary storage slot is connected to the operating port 101. Then the cover 120 moves to open the operating port 101, and the replaced battery 001 is inserted into the temporary storage slot through the operating port 101. The motor drives the rotating frame 210 to rotate so that the receiving slot 201 loaded with a fully charged battery 001 is connected to the operating port 101, and the fully charged battery 001 is taken away through the operating port 101. At this time, the unloaded receiving slot 201 is changed to a new temporary storage slot. The motor drives the rotating frame 210 to rotate so that the battery 001 with the lowest power is connected to the contact 2212 as a load battery. During the rotation of the motor-driven rotating frame 210, the connection between the battery replacement unit 200 and the power supply is temporarily cut off, thereby preventing the contact 2212 and the synchronization ring 2211 from being connected to a connecting section 2221 at the same time, thereby destroying the non-conductive state between the contact 2212 and the synchronization ring 2211.

[0056] When an electric vehicle uses the charging service, the interactive interface 340 is operated to pull out the charging gun 330 and connect it to the charging port of the electric vehicle for charging. After charging is completed, the charging gun 330 is separated from the charging port, and the cable drum 350 reels the charging cable 320 through the elastic force of the coil spring, and the charging gun 330 is reset accordingly. When the charging power of the electric vehicle is insufficient or unstable due to grid load fluctuations, the conversion switch 230 switches the load battery to a discharge state, and assists the charging gun 330 in charging the electric vehicle, thereby maintaining a stable power supply for the electric vehicle and reducing the risk of battery damage.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
