[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] The present invention will be further described below with reference to the embodiments.

[0036] Example 1

[0037] Please refer to Figures 1-5. A smart inspection robot for charging piles includes a support frame 1; a translation component 2 for driving the smart inspection robot to move is fixedly connected to the top of the support frame 1; a horizontal rotation component 3 for horizontal rotation is fixedly connected to the support frame 1; an electric scissor lift bracket 4 for height adjustment is fixedly connected to the driving end of the horizontal rotation component 3; a camera 6 for taking pictures of the exterior is fixedly connected to the bottom of the electric scissor lift bracket 4; and a charging gun plugging / unplugging component 5 for plugging and unplugging the charging gun is fixedly connected to one end of the bottom of the electric scissor lift bracket 4.

[0038] The charging gun plug-in assembly 5 includes a vertical rotation assembly, a push-pull assembly, a clamping assembly, and an unlocking assembly. The vertical rotation assembly is fixedly connected to one bottom end of the electric scissor lift bracket 4. The vertical rotation assembly is fixedly connected to the push-pull assembly. The push-pull assembly is fixedly connected to the clamping assembly. The clamping assembly can fit and contact the outer wall of the charging gun. The clamping end of the clamping assembly is fixedly connected to the unlocking assembly for the mechanical lock unlocking button of the charging gun.

[0039] The translation component 2 is fixedly connected to the existing sunshade bracket of the charging station. Camera 6 is a camera with no blind spots.

[0040] In use, the electric scissor lift bracket 4 moves the camera 6 to the top. The vertical rotation component of the charging gun plug-in assembly 5 drives the push-pull component, clamping component, and unlocking component to rotate parallel to the electric scissor lift bracket 4. The translation component 2 moves the support frame 1, the support frame 1 moves the horizontal rotation component 3, and the horizontal rotation component 3 moves the electric scissor lift bracket 4. The electric scissor lift bracket 4 moves the camera 6 and the charging gun plug-in assembly 5 to the outer side above the charging station to be inspected. During appearance inspection, the electric scissor lift bracket 4 moves the camera 6 downward, and the camera 6 takes a picture or video of one side of the charging pile, transmitting the data to the control terminal for evaluation. Then, the horizontal rotation component 3 moves the camera 6 to the next side of the charging pile, and the electric scissor lift bracket 4 moves the camera 6 upward to take a picture or video, transmitting the data to the control terminal for evaluation. The above actions are repeated to perform appearance inspection on the other two sides, achieving all-round appearance inspection of the charging pile.

[0041] When the charging gun is visible on the exterior of the charging station, the vertical rotating component drives the clamping component to rotate above the charging gun. The electric scissor lift bracket 4 moves the clamping end of the clamping component to the outside of the charging gun, where the clamping component clamps the charging gun. The unlocking component unlocks the mechanical lock button on the charging gun. Then, the push-pull component pushes the clamping component to move, pulling the charging gun out of the charging station. The camera 6 then performs an appearance inspection of the charging end of the charging gun. After the camera 6 finishes its appearance inspection of the charging gun, the unlocking component separates from the mechanical lock button on the charging gun. The push-pull component pushes the clamping component to move, inserting the charging gun into the charging station. The mechanical lock on the charging gun is then connected to the charging station. The clamping component separates from the charging gun, and the electric scissor lift bracket 4 moves the clamping component upward, thus completing the appearance inspection of the charging gun. This process of inspecting the appearance of both the charging station and the charging gun is beneficial for practical use.

[0042] In this embodiment, the translation component 2 includes a first motor 21, a gear ring 22, a rack 23, a guide rail 24, and rollers 25. The first motor 21 is fixedly installed on the top of the side wall of the support frame 1 near the horizontal rotation component 3. The output end of the first motor 21 rotates through the side wall of the support frame 1 and is fixedly installed with the gear ring 22. The rack 23 is installed on the top of the side wall of the support frame 1 away from the horizontal rotation component 3. The gear ring 22 and the rack 23 are meshed and connected. Two rollers 25 are fixedly installed at equal intervals on the bottom of the side wall of the support frame 1 away from the horizontal rotation component 3, and the bottom of both rollers 25 are in contact with and rotatably connected to the guide rail 24. The rack 23 and the guide rail 24 are both fixedly connected to the existing sunshade bracket of the charging station.

[0043] In use, the first motor 21 drives the gear ring 22 to rotate. The gear ring 22 rotates along the rack 23. With the cooperation of the guide rail 24 and the roller 25, the gear ring 22 drives the support frame 1 to move along the guide rail 24. The support frame 1 drives the charging gun plugging and unplugging assembly 5 and the camera 6 to move above the charging pile that needs to be detected.

[0044] The horizontal rotation component 3 includes a second motor 31 and a horizontal plate 32. The second motor 31 is fixedly installed on the top of the end of the support frame 1 away from the translation component 2. One end of the horizontal plate 32 is fixedly connected to the drive end of the second motor 31, and the other end of the horizontal plate 32 is fixedly connected to the top of the electric scissor lift bracket 4. After the camera 6 has finished inspecting one surface, the second motor 31 drives the horizontal plate 32 to rotate 90 degrees. The horizontal plate 32 then drives the camera 6 to rotate to the next surface of the charging pile for continued inspection. This facilitates driving the camera 6 to rotate along the charging pile, enabling the inspection of each surface of the charging pile.

[0045] The vertical rotation assembly includes a third motor 51 and a connecting plate 52. The top of the connecting plate 52 is fixedly connected to one bottom end of the electric scissor lift bracket 4, and the upright part of the connecting plate 52 is fixedly connected to the third motor 51. The output end of the third motor 51 is fixedly connected to the push-pull assembly. The output shaft of the third motor 51 is arranged parallel to the electric scissor lift bracket 4.

[0046] The push-pull assembly includes a connecting frame 53, an electric push rod 54, a slide rod 55, and a moving plate 56. The connecting frame 53 is fixedly connected to the output end of the third motor 51. The electric push rod 54 is fixedly installed inside the connecting frame 53. The drive end of the electric push rod 54 is fixedly connected to the moving plate 56. The slide rod 55 is fixedly connected to the outer side of the connecting frame 53 away from the third motor 51. A sliding hole is opened on the end of the moving plate 56 near the electric push rod 54. The slide rod 55 slides through the sliding hole. The end of the moving plate 56 away from the electric push rod 54 is fixedly connected to the clamping assembly.

[0047] The clamping assembly includes a pressure block 510, a symmetrical linear module 511, and an arc-shaped clamping plate 513. The symmetrical linear module 511 is fixedly installed at the bottom of the end of the moving plate 56 away from the electric push rod 54. The two output ends of the symmetrical linear module 511 are fixedly connected to the arc-shaped clamping plate 513. The top of the inner wall of the two arc-shaped clamping plates 513 are fixedly connected to the pressure block 510. One of the arc-shaped clamping plates 513 is fixedly connected to the unlocking assembly. The inner wall of the arc-shaped clamping plate 513 is in close contact with the outer wall of the charging gun, and the bottom of the pressure block 510 can be in close contact with the top of the grip of the charging gun.

[0048] The unlocking assembly includes a horizontal support plate 57, a push-pull electromagnet 58, a straight groove 59, and a push plate 512. The horizontal support plate 57 is fixedly installed on the outer wall of one of the arc-shaped clamps 513. The push-pull electromagnet 58 is fixedly installed on the horizontal support plate 57. The push plate 512 is fixedly installed on the drive end of the push-pull electromagnet 58. The arc-shaped clamp 513 connected to the support plate 57 has a straight groove 59 on its upright part, and the push plate 512 slides in the straight groove 59.

[0049] In use, the electric scissor lift bracket 4 moves the camera 6 to the top, the third motor 51 drives the connecting frame 53 to rotate, the connecting frame 53 drives the moving plate 56 to rotate, and the moving plate 56 drives the clamping component and the unlocking component to rotate parallel to the electric scissor lift bracket 4; then the second motor 31 drives the horizontal rotating component 3 to rotate. Since the distance from the clamping component to the central axis of the second motor 31 is less than the distance from the electric scissor lift bracket 4 to the central axis of the second motor 31, the rotation of the clamping component and the unlocking component to be parallel to the electric scissor lift bracket 4 reduces the possibility of the clamping component and the unlocking component hitting the charging pile shell when rotating.

[0050] When the charging gun is on the outer surface of the charging pile, the third motor 51 drives the connecting frame 53 to rotate, the connecting frame 53 drives the moving plate 56 to rotate, the moving plate 56 drives the clamping assembly to rotate above the charging gun, the symmetrical linear module 511 drives the two arc-shaped clamping plates 513 to move outward, the push-pull electromagnet 58 is energized to drive the push plate 512 to move downward, when the electric scissor bracket 4 drives the two arc-shaped clamping plates 513 to move to the outside of the charging gun, the symmetrical linear module 511 drives the two arc-shaped clamping plates 513 to move towards the charging gun, the two arc-shaped clamping plates 513 are in contact with the outer wall of the charging gun, at this time the bottom of the pressure block 510 is in contact with the top of the charging gun's grip, thus clamping the charging gun;

[0051] When the push-pull electromagnet 58 drives the push plate 512 to move upward along the straight groove 59, the push plate 512 moves upward and contacts the charging gun mechanical lock unlock button, pushing the charging gun mechanical lock unlock button upward to unlock it. Then, the electric push rod 54 drives the moving plate 56 to move, and the moving plate 56 moves along the slide rod 55. The moving plate 56 pushes the charging gun held by the arc-shaped clamping plate 513 and the pressure block 510 to move, pulling the charging gun out of the charging pile. Then, the rotating camera 6 performs an appearance inspection of the charging end of the charging gun. After the camera 6 finishes the appearance inspection of the charging gun, the push-pull electromagnet 58 drives the push plate 512 to move downward and separate from the charging gun mechanical lock unlock button. The electric push rod 54 drives the push clamping assembly to move, and the two arc-shaped clamping plates 513 insert the charging gun into the charging pile. The charging gun mechanical lock is connected to the charging pile, and the clamping assembly is separated from the charging gun. The electric scissor bracket 4 drives the clamping assembly to move upward, realizing the appearance inspection of the charging gun. This achieves the appearance inspection of the charging pile and the charging gun, which is beneficial for practical use.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
