[0017] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0018] like Figure 1-11As shown, this invention provides a modular electric vehicle charging robot assembly structure, including a charging base station 1, a charging robot 2, and two batteries 3. One battery 3 is charged in the charging base station 1, and the other is used directly by the charging robot 2. By having the two batteries 3 alternately power the charging robot 2, the charging robot 2 avoids downtime due to waiting for a single battery 3 to charge, ensuring continuous operation.

[0019] The charging robot 2 includes a vehicle body 11, on which a charging gun 12 connected to the battery 3 and used to charge the electric vehicle is installed, as well as a touch panel 13 for controlling the charging. During charging, the charging gun 12 can be unlocked via the touch panel 13. The vehicle body 11 is provided with a battery mounting cavity 14, which is a through-hole design, allowing the battery 3 to be removed from both the left and right sides of the vehicle body 11.

[0020] The power replenishment base station 1 includes a docking station 6 and a charging station 8. The docking station 6 is used to allow the charging robot 2 to stop during the power replenishment process. The bottom of the docking station 6 is equipped with a lifting mechanism 7, which is used to lift the charging robot 2 during the power replenishment process to eliminate the height difference between the bottom surface of the battery 3 to be replaced and the bottom surface of the battery mounting cavity 14 in the charging station 8.

[0021] One embodiment of this application is: the lifting mechanism 7 directly lifts the rigid vehicle body 11, which can avoid the height error caused by tire deformation after the battery 3 is removed.

[0022] The charging station 8 is equipped with a battery transport mechanism 9 and a charging connection mechanism 10. The battery transport mechanism 9 is used to move the battery 3 between the charging robot 2 and the charging station 8, and the charging connection mechanism 10 is used to electrically connect with the battery 3 in the charging station 8 to charge it.

[0023] One embodiment of this application is as follows: two charging stations 8 are provided, and the two charging stations 8 are located on opposite sides of the docking station 6. During the recharging process of the charging robot 2, one charging station 8 stores the replaced battery 3, and the other charging station 8 stores the battery 3 to be installed.

[0024] Two limiting grooves 4 are provided at the bottom of the battery 3, and a battery limiting mechanism 15 is provided at the bottom of the battery mounting cavity 14, which matches the position of the limiting grooves 4 of the battery 3. The limiting grooves 4 and the battery limiting mechanism 15 cooperate to position the battery 3 and prevent the battery 3 from moving on the vehicle body 11. A first connector 5 is provided in one of the limiting grooves 4 of the battery 3, and a second connector 16 adapted to the first connector 5 is provided on the top surface of the battery limiting mechanism 15 opposite to it, which is used to connect the battery 3 to the electrical equipment in the vehicle body 11 and transmit the power of the battery 3 to the electrical equipment in the charging robot 2.

[0025] The working process of the combined structure is as follows: When the charging robot 2's battery 3 is low on power, it autonomously drives to the docking station 6 and precisely stops. The lifting mechanism 7 at the bottom of the docking station 6 is activated, raising the charging robot 2 to a height where the bottom of its battery mounting cavity 14 is flush with the bottom surface of the battery 3 in the charging station 8. If there is no battery 3 in the left charging station 8 at this time, the battery transport mechanism 9 of the left charging station 8 extends into the battery mounting cavity 14 of the charging robot 2, triggering the battery limiting mechanism 15 to unlock. The battery transport mechanism 9 grabs the battery 3 to be charged from the charging robot 2 and moves it back to the left charging station 8, then connects the first connector 5 of the battery to the charging connection mechanism 10 of the left charging station 8. The battery transport mechanism 9 of the right charging station 8 pushes the fully charged battery 3 from the right side of the battery mounting cavity 14 into the battery mounting cavity 14. After the battery 3 is in place, the battery limiting mechanism 15 automatically locks and powers on, completing the replacement of the battery 3. By rotating the two batteries 3, the charging robot 2's recharging time is effectively reduced, and the operating efficiency of the charging robot 2 is improved.

[0026] The docking station 6 includes a platform 17, with a lifting mechanism 7 installed at the center of the platform 17. The lifting mechanism 7 is a scissor lift. The charging station 8 includes a base 18 for placing the battery 3. The top of the base 18 is equipped with a protective box 19 to prevent interference from the external environment. The protective box 19 has a cavity 20 on the side closest to the docking station 6 to provide an access channel for the battery handling mechanism 9, ensuring that the battery 3 can move smoothly between the charging station 8 and the charging robot 2.

[0027] During operation, the lifting mechanism 7 lifts the charging robot 2 to a height where the bottom of the battery mounting cavity 14 is flush with the base 18. The battery transport mechanism 9 passes through the through cavity 20 to remove the battery 3 to be replaced from the battery mounting cavity 14, and then passes through the through cavity 20 to move it into the protective box 19.

[0028] The battery handling mechanism 9 includes two first movable slots 21 symmetrically opened on the top of the base 18. Movable plates 22 that can slide horizontally along the first movable slots 21 are slidably installed in each of the two first movable slots 21. Threaded rods 23 are installed at the bottom of the first movable slots 21, and the movable plates 22 and the threaded rods 23 are threadedly connected. A motor 24 is fixedly installed on one side of the base 18, and the motor 24 is connected to the threaded rods 23 through a transmission.

[0029] During operation, the motor 24 drives the threaded rod 23 to rotate, and the rotation of the threaded rod 23 causes the movable plate 22, which is threadedly connected to it, to move left and right, so that the movable plate 22 extends or retracts from the through cavity 20 of the corresponding protective box 19.

[0030] The movable plate 22 has grooves 25 at both ends of its top. A fixed clamping plate 26 is rotatably mounted on the side of the two grooves 25 that are close to each other. A gear 27 is fixedly connected to the rotating shaft of the fixed clamping plate 26. A mounting groove 28 is provided in the middle of the movable plate 22. A double-headed electric push rod 31 is installed in the mounting groove 28. A rack 30 is provided in each of the two grooves 25. The rack 30 is connected to the double-headed electric push rod 31 and can slide left and right. The rack 30 is meshed with the gear 27.

[0031] One embodiment of this application is as follows: movable blocks 29 that can slide left and right are respectively installed on the left and right sides of the mounting groove 28. A rack 30 passing through the side wall of the groove 25 is provided on the side of the movable block 29 near the groove 25. The rack 30 is meshed with the gear 27, and the two pushing ends of the double-headed electric push rod 31 are respectively connected to the two movable blocks 29 for transmission.

[0032] During operation, when battery 3 is grasped, the dual-headed electric push rod 31 is activated, causing the two movable blocks 29 to move away from each other. The two racks 30 move in opposite directions, and the racks 30, through the gear 27, cause the suspended end of the fixed clamping plate 26 to rotate out of the groove 25 and clamp the main battery 3. When battery 3 is lowered, the dual-headed electric push rod 31 is activated, causing the two movable blocks 29 to move closer to each other. The racks 30 and gear 27 in sequence drive the fixed clamping plate 26 to rotate in the opposite direction, and the suspended end of the fixed clamping plate 26 retracts into the groove 25, making it easy for the movable plate 22 to move directly out from under battery 3.

[0033] The charging connection mechanism 10 includes a square groove 32 opened on the top of the base 18. A movable block 33 is slidably installed in the square groove 32. A third connector 34 adapted to the first connector 5 is provided on the top of the movable block 33. An electric push rod 35 is installed at the bottom of the square groove 32. The pushing end of the electric push rod 35 is connected to the bottom of the movable block 33, which can control the lifting and lowering of the third connector 34.

[0034] During operation, the battery transport mechanism 9 moves the battery 3 to the set position in the charging station 8, and then the electric push rod 35 is activated and pushes the moving block 33 upward, so that the third connector 34 is connected to the first connector 5, completing the electrical connection between the charging station 8 and the battery 3. After that, the charging station 8 can recharge the battery 3.

[0035] The battery limiting mechanism 15 includes two second movable grooves 36 located on the bottom surface of the battery mounting cavity 14, opposite to the position of the first movable groove 21. A through groove 37 is formed at the bottom of each second movable groove 36, and a first slider 38 that can slide up and down is installed within the through groove 37. Below the first slider 38, a rotating rod 43 is horizontally positioned, with its head connected to the vehicle body 11 and its suspended end capable of swinging up and down. A first strip groove 44 and a second strip groove 45 are formed in the middle and at the suspended end of the rotating rod 43, respectively. The first slider 38 is connected to the first strip groove 44 via a first vertical rod 46.

[0036] The suspended end of the rotating rod 43 is located directly below the battery limiting mechanism 15. A reset cavity 39 for accommodating the battery limiting mechanism 15 is provided between the suspended end of the rotating rod 43 and the battery limiting mechanism 15. A second slider 40 is slidably installed inside the reset cavity 39. The battery limiting mechanism 15 is provided on the top surface of the second slider 40. A through hole is provided on the top surface of the reset cavity 39 to facilitate the extension of the battery limiting mechanism 15. The second slider 40 is used to limit the extension length of the battery limiting mechanism 15. A second vertical rod 47 is provided below the second slider 40. The lower end of the second vertical rod 47 passes through the bottom surface of the reset cavity 39 and is movably connected to the second strip groove (45) at the suspended end of the rotating rod 43. A spring (50) is sandwiched between the battery limiting mechanism (15) and the bottom surface of the reset cavity.

[0037] In one embodiment of this application, the bottom ends of the first vertical rod 46 and the second vertical rod 47 are respectively provided with a sliding pin 48 and a sliding pin 49. The sliding pin 48 and the sliding pin 49 are respectively inserted into the first strip groove 44 and the second strip groove 45 to drive the first vertical rod 46 and the second vertical rod 47 to move up and down.

[0038] During operation, as the battery 3 is removed from the charging robot 2, the movable plate 22 enters the second movable slot 36 (the end of the movable plate 22 near the docking station 6 and both sides of the top of the first slider 38 are inclined). The movable plate 22 pushes the first slider 38 down, and the first slider 38 pushes the suspended end of the rotating rod 43 downward through the first vertical rod 46. During the downward rotation of the suspended end of the rotating rod 43, the second vertical rod 47 is pulled down, compressing the spring 50 and driving the second slider 40 to move downward. The second slider 40 then drives the battery limiting mechanism 15 to leave the limiting slot 4 of the battery 3, and at the same time, the second connector 16 is separated from the first connector 5, releasing the locked state of the battery 3 and the electrical connection between the battery 3 and the vehicle body 11.

[0039] Similarly, after the battery 3 is moved into the charging mounting position, the movable plate 22 leaves the second movable groove 36, the force applied to the first slider 38 is canceled, and the restoring force of the spring 50 pushes the second slider 40 upward, so that the battery limiting mechanism 15 extends out of the bottom surface of the battery mounting cavity 14 and enters the limiting groove 4 of the battery 3, so that the first connector 5 and the second connector 16 are connected, realizing the electrical connection between the battery 3 and the vehicle body 11 in the power-off state.

[0040] The bottom of the battery mounting cavity 14 and the top of the base 18 are both equipped with rollers 51 to reduce the resistance of the battery 3 to movement.

[0041] The embodiments of the present invention are given for the purposes of illustration and description. Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
