[0034] Embodiment

[0035] Refer to Figure 1 As shown, an electric vehicle front-end battery swapping system provided in this embodiment includes an electric vehicle 1, a transfer trolley 2, a battery swapping cabinet 3, and a parking platform 4;

[0036] A frame 5 and a battery compartment 6 located inside the frame 5 are provided at the bottom of the electric vehicle 1. The frame 5 is provided with a locking device 7 for fixing or releasing the battery compartment 6, such as Figure 2 and Figure 3 As shown, an opening structure for the battery to enter and exit the battery compartment 6 is provided on any side wall of the battery compartment 6, and a fixing structure for fixing the battery is provided inside the battery compartment 6;

[0037] It should be noted that, as Figure 4 shown, the bottom of the frame 5 is open, enabling the battery compartment 6 to enter and exit the inside of the frame 5.

[0038] The transfer trolley 2 is provided with a platform part, a moving part, and a lifting part. As Figure 5 shown, the platform part is provided with an angle measurement component 8 and an angle adjustment component 9 that are electrically connected to each other;

[0039] Specifically, the angle measurement component 8 is used to measure and record the relative position and angle between the side wall of the battery compartment 6 and the periphery of the platform part after the transfer trolley 2 picks up the battery compartment 6 from the frame 5;

[0040] The angle adjustment component 9 is used to adjust the relative position and angle between the side wall of the battery compartment 6 and the periphery of the platform part, that is, to adjust the battery compartment 6 to the relative position and angle between the side wall of the battery compartment 6 and the periphery of the platform part recorded by the angle measurement component 8, or to adjust the relative position and angle between the side wall of the battery compartment 6 and the periphery of the platform part so that the battery in the battery compartment 6 meets the position and angle standards for entering the inside of the battery swapping cabinet 3.

[0041] As Figure 6As shown, the battery swapping cabinet 3 is provided with a battery fetching and delivering device 10. The battery fetching and delivering device 10 is used to take out the battery in the battery swapping cabinet 3 and transfer the battery to the battery compartment 6 on the transfer trolley 2, or pick up the battery from the battery compartment 6 on the transfer trolley 2 and put the battery into the battery swapping cabinet 3.

[0042] The front end and the rear end of the parking platform 4 have slopes. The parking platform 4 is used to dock the electric vehicle 1, which can ensure the effective operation of the battery swapping process, ensure that the battery compartment 6 has enough space to move up and down to get out of the frame 5, and when the electric vehicle 1 drives above the parking platform 4, the ground clearance of the chassis of the electric vehicle 11 can be increased.

[0043] In addition, in order to increase the endurance of the electric vehicle 1, refer to Figure 4 As shown, a plurality of frames 5 are provided at the bottom of the electric vehicle 1, and a battery compartment 6 is provided in each of the plurality of frames 5. The plurality of battery compartments 6 are arranged in a manner parallel or perpendicular or a combination of parallel and perpendicular to the driving direction of the electric vehicle 1 ( Figure 4 One of the arrangement ways is shown).

[0044] Specifically, the transfer trolley 2 is also provided with a rotating part, and the rotating part can drive the platform part to rotate 90° in the clockwise direction or the counterclockwise direction. Specifically, when the arrangement direction of the battery compartment 6 is perpendicular to the driving direction of the electric vehicle, the battery compartment 6 can be adjusted to be parallel to the driving direction of the electric vehicle 1 through the rotation of the rotating part, so as to ensure that the battery inside can smoothly enter the battery swapping cabinet 3 after the angle of the battery compartment 6 is adjusted by the angle adjustment component 9.

[0045] Specifically, there are two rows of charging positions 13 on the left and right inside the battery swapping cabinet 3, and the battery fetching and delivering device 10 is located between the two rows of charging positions 13 on the left and right.

[0046] Refer to Figure 1 As shown, a track 11 is provided between the battery swapping cabinet 3 and the parking platform 4. One end of the battery swapping cabinet 3 facing the electric vehicle 1 is provided with a cabinet door. One end of the track 11 passes through the cabinet door and extends into the battery swapping cabinet 3, and the other end of the track 11 extends to the position of the parking platform 4. The transfer trolley 2 runs on the track 11 and enters and exits the battery swapping cabinet 3 through the cabinet door.

[0047] Specifically, the other end of the track 11 extends at least below the frame 5 of the electric vehicle 1 to ensure that the transfer trolley 2 can move below the battery compartment 6 to catch the battery compartment 6.

[0048] The transfer trolley 2 runs on the track 11 and enters and exits the battery swapping cabinet 3 through the cabinet door, so that the transfer trolley 2 can transport the battery inside the battery swapping cabinet 3. When the entire electric vehicle 1 battery swapping system is not operating, the transfer trolley 2 can move into the battery swapping cabinet 3 to avoid damage to the transfer trolley 2 caused by external reasons.

[0049] It should be noted that, as Figure 7 shown, the parking platform 4 specifically refers to two corresponding single-sided bridge structures. The parking platform 4 further includes a parking baffle 12, a left-right moving device, and a guardrail. The parking baffle 12 can be lifted or lowered to limit the parking position of the vehicle on the parking platform 4.

[0050] Specifically, an opening structure for the battery to enter and exit the battery compartment 6 is provided on the side wall of the battery compartment 6 facing the battery swapping cabinet 3.

[0051] Specifically, the battery swapping process of this embodiment is as follows:

[0052] The battery swapping vehicle drives onto the parking platform 4. The transfer trolley 2 moves to the bottom end of the frame 5, and the lifting part drives the platform part to closely adhere to the bottom of the battery compartment 6. The locking device 7 releases the battery compartment 6, and the lifting part drives the platform part to descend. (It should be noted that when the battery compartment is perpendicular to the driving direction of the electric vehicle, the rotating part also needs to drive the platform part to rotate 90° clockwise or counterclockwise). The angle measurement component 8 measures and records the relative position and angle between the side wall of the battery compartment 6 and the periphery of the platform part. After the recording is completed, the angle adjustment component 9 adjusts the relative position and angle between the side wall of the battery compartment 6 and the periphery of the platform part to make the battery meet the position and angle standards for entering the interior of the battery swapping cabinet 3. The transfer trolley 2 drives the battery compartment 6 towards the battery swapping cabinet 3. After the transfer trolley 2 moves into place, the battery picking and delivering device 10 grabs the battery inside the battery compartment 6 and places it into the battery swapping cabinet 3, and then takes out the fully charged battery in the battery swapping cabinet 3 and transfers it into the battery compartment 6 on the transfer trolley 2. The transfer trolley 2 drives the battery compartment 6 towards the parking platform 4. After the transfer trolley 2 moves to the bottom end of the frame 5, (it should be noted that when the battery compartment is perpendicular to the driving direction of the electric vehicle, the rotating part also needs to drive the platform part to rotate 90° counterclockwise or clockwise), the angle adjustment component 9 adjusts the battery compartment 6 to the relative position and angle between the side wall of the battery compartment 6 and the periphery of the platform part recorded by the angle measurement component 8. The lifting part drives the platform part to rise, the battery compartment 6 enters the interior of the frame 5 and is fixed by the locking device 7, the lifting part drives the platform part to descend, and the transfer trolley 2 resets, completing the battery swapping.

[0053] In this article, specific examples are used to elaborate on the principles and implementation manners of the present utility model. The descriptions of the above embodiments are only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, based on the idea of the present utility model, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present utility model.
