[0015] A detection method for a charging port cover inspection tool of a new energy vehicle includes the following specific operation steps:

[0016] S1. When in use, after the charging port cover of the new energy vehicle is placed inside the inspection fixture and fixed by the staff, the staff pulls the power rod upward. Through the inclined plane of the triangular block, the power rod can push the first trapezoidal blocks on the two limit frames to move relatively away from each other, and the first trapezoidal blocks drive the limit frames to compress the spring. At the same time, the two limit frames drive the two first positioning blocks to move relatively away from each other. After the staff places the charging port cover of the new energy vehicle inside the inspection fixture, the staff releases the power rod, and the spring drives the limit frame to reset, so that the limit frame can initially position and fix the charging port cover of the new energy vehicle through the first positioning block;

[0017] S2. Since the bottom of the second positioning block is provided with an inclined plane, rubber layers are provided on the bottom of the second positioning block and the first positioning block. The bottom of the moving rod is fixedly connected with a tension spring, and the bottom end of the tension spring is fixedly connected with the inner wall of the first positioning block. The compression and reset of the tension spring can be realized through the up and down movement of the moving rod. Therefore, during the positioning process of the charging port cover of the new energy vehicle, certain protection can be obtained. The second positioning block can perform a certain extrusion positioning on the top of the charging port cover of the new energy vehicle, making the initial installation and positioning of the charging port cover of the new energy vehicle more stable. And through the inclined plane provided at the bottom of the second positioning block, when the second positioning block moves in the direction close to the charging port cover of the new energy vehicle, it can move upward, so that the bottom of the second positioning block closely adheres to the top of the charging port cover of the new energy vehicle, making the positioning of the charging port cover of the new energy vehicle smoother;

[0018] S3. The staff starts the motor. The motor drives the transmission plate to rotate through the rotating disk. The transmission plate drives the transmission disk to rotate 90 degrees through the mutual cooperation of the transmission rod and the transmission groove. At the same time, during the rotation of the transmission disk, the rotating disk slides out of the inside of the arc groove, and the transmission disk turns into the inside of the groove. At the same time, the transmission disk drives the rotating shaft to rotate, and the rotating shaft drives the connecting rod and the base to rotate 90 degrees. During the rotation of the pressure rod, it rotates in the direction close to the charging port cover of the new energy vehicle. When the base slides to the bottom of the stable pressure rod, through the inclined groove opened at the bottom of the stable pressure rod, the second positioning block and the power rod move downward to a certain extent when sliding into the inclined groove. After the second positioning block and the power rod slide to the bottom of the stable pressure rod, the stable pressure rod can block the second positioning block and the power rod, making the second positioning block more closely fit the top of the charging port cover of the new energy vehicle, and the power rod pushes the two first trapezoidal blocks to move relatively close to each other through the second trapezoidal block, making the two first positioning blocks more stably clamp and fix the charging port cover of the new energy vehicle;

[0019] S4. Meanwhile, blocked by the chute and restricted by the stabilizing pressure rod, the pressure rod closely adheres to the top of the charging port cover of the new energy vehicle and further stabilizes the charging port cover of the new energy vehicle, thus making the detection and positioning of the charging port cover of the new energy vehicle more stable. When the base at the bottom of the stabilizing pressure rod rotates again after inspection, the positioning of the pressure rod, the second positioning block, and the power rod is released by the stabilizing pressure rod, enabling the staff to more conveniently remove the inspected charging port cover of the new energy vehicle. Through the cyclic intermittent rotation of multiple bases of the device, the detection speed of the charging port cover of the new energy vehicle by the device is increased to a certain extent.

[0020] The advantages of the present invention are as follows:

[0021] 1. For the inspection tool and inspection method of the charging port cover of a new energy vehicle of the present invention, the stabilizing pressure rod can block the second positioning block and the power rod, making the second positioning block more closely fit the top of the charging port cover of the new energy vehicle, and enabling the power rod to push two first trapezoidal blocks to move relatively closer through the second trapezoidal block, making the two first positioning blocks more stably clamp and fix the charging port cover of the new energy vehicle. Meanwhile, blocked by the chute and restricted by the stabilizing pressure rod, the pressure rod closely adheres to the top of the charging port cover of the new energy vehicle and further stabilizes the charging port cover of the new energy vehicle, thus making the detection and positioning of the charging port cover of the new energy vehicle more stable.

[0022] 2. For the inspection tool and inspection method of the charging port cover of a new energy vehicle of the present invention, when the base at the bottom of the stabilizing pressure rod rotates again after inspection, the positioning of the pressure rod, the second positioning block, and the power rod is released by the stabilizing pressure rod, enabling the staff to more conveniently remove the inspected charging port cover of the new energy vehicle. Through the cyclic intermittent rotation of multiple bases of the device, the detection speed of the charging port cover of the new energy vehicle by the device is increased to a certain extent.

[0023] 3. For the inspection tool and inspection method of the charging port cover of a new energy vehicle of the present invention, the spring drives the limit frame to reset, enabling the limit frame to initially position and fix the charging port cover of the new energy vehicle through the first positioning block, increasing the positioning and placing speed of the charging port cover of the new energy vehicle to a certain extent, and enabling the charging port cover of the new energy vehicle to be detected more smoothly.

The inside of the first adjusting rod 25 is a hollow structure. The surface of the second adjusting rod 26 is slidably connected to the inside of the first adjusting rod 25. A stable pressing rod 24 is fixedly connected to the bottom of the first adjusting rod 25. The placed new energy vehicle charging port cover can be stably positioned by the stable pressing rod 24, so as to facilitate the detection of the new energy vehicle charging port cover. An inclined slot 23 is opened on one side of the stable pressing rod 24. The upper surface inside the inclined slot 23 is an inclined plane. An intermittent transmission device is arranged at the bottom of the workbench 1.

[0038] Specifically, the transmission positioning device includes a power rod 15. The surface of the power rod 15 is slidably connected to the inside of the chute 16. The power rod 15 is arranged between the two limiting frames 12. A positioning slot 17 is opened on the side of the power rod 15 close to the limiting frame 12.

The cross-section of the triangular block 19 is triangular. A spring 13 is fixedly connected to the side of the limiting frame 12 away from the power rod 15. One end of the spring 13 away from the limiting frame 12 is fixedly connected to the inner wall of the power slot 11. The spring 13 can be compressed and reset by the movement of the limiting frame 12.

[0039] The power lever 15 is pulled upward by the staff. Through the inclined plane of the triangular block 19, the power lever 15 can push the first trapezoidal blocks 14 on the two limiting frames 12 to move relatively away from each other, and the first trapezoidal blocks 14 drive the limiting frames 12 to compress the spring 13. At the same time, the two limiting frames 12 drive the two first positioning blocks 10 to move relatively away from each other. After the staff places the new energy vehicle charging port cover into the inspection tool 5, the staff releases the power lever 15. The spring 13 drives the limiting frame 12 to reset, and the limiting frame 12 can initially position and fix the new energy vehicle charging port cover through the first positioning block 10, and the positioning and placing speed of the new energy vehicle charging port cover is increased to a certain extent, enabling the new energy vehicle charging port cover to be detected more smoothly.

[0040] The inside of the first positioning block 10 is a hollow structure.

Rubber layers are provided at the bottom of the second positioning block 22 and on the first positioning block 10. A tension spring 20 is fixedly connected to the bottom of the moving rod 21. The bottom end of the tension spring 20 is fixedly connected to the inner wall of the first positioning block 10. The tension spring 20 can be compressed and reset by the up and down movement of the moving rod 21. Thus, during the positioning process of the new energy vehicle charging port cover, it can be protected to a certain extent. The top of the new energy vehicle charging port cover can be squeezed and positioned to a certain extent through the second positioning block 22, making the initial installation and positioning of the new energy vehicle charging port cover more stable. And through the inclined plane provided at the bottom of the second positioning block 22, when the second positioning block 22 moves in the direction close to the new energy vehicle charging port cover, it can move upward, making the bottom of the second positioning block 22 closely adhere to the top of the new energy vehicle charging port cover and making the positioning of the new energy vehicle charging port cover smoother.

[0041] A support seat 6 is fixedly connected to the top of the base 4. A pressure lever 7 is rotatably connected inside the support seat 6 through a shaft. A groove is provided at the bottom of the pressure lever 7. The pressure lever 7 can reposition and fix the top of the new energy vehicle charging port cover. Two torsion springs 8 movably sleeved on the shaft are fixedly connected to both sides of the pressure lever 7. The side of the torsion spring 8 away from the pressure lever 7 is fixedly connected to the inner wall of the support seat 6. The torsion spring 8 can be compressed and reset by the rotation of the pressure lever 7. In the natural state, the pressure lever 7 is inclined.

[0042] A threaded rod 29 extending outside the stabilizing pressure lever 24 is rotatably connected inside the first adjusting rod 25. The surface of the threaded rod 29 is threadedly connected to the inside of the second adjusting rod 26. The position of the stabilizing pressure lever 24 can be adjusted by the rotation of the threaded rod 29.

[0043] The intermittent transmission device includes a fixed mounting frame 30. The top of the fixed mounting frame 30 is fixedly connected to the bottom of the workbench 1. An electric motor 32 is fixedly connected inside the fixed mounting frame 30. The output end of the electric motor 32 is fixedly connected to a rotating disk 31. A groove 33 is formed on the outer surface of the rotating disk 31. The bottom of the rotating shaft 2 is fixedly connected to a transmission disk 35. An arc-shaped groove 34 that is slidably connected to the rotating disk 31 is formed on the outer surface of the transmission disk 35. The number of arc-shaped grooves 34 is four, and the four arc-shaped grooves 34 are arranged in a circular array on the transmission disk 35. Four transmission grooves 38 are formed on the top of the transmission disk 35, and the four transmission grooves 38 are also arranged in a circular array on the transmission disk 35. One transmission groove 38 is arranged between two adjacent arc-shaped grooves 34. The bottom of the rotating disk 31 is fixedly connected to a transmission plate 36. A transmission rod 37 that is movably connected to the inside of the transmission groove 38 is fixedly connected to the top of the transmission plate 36.

[0044] By the staff starting the electric motor 32, the electric motor 32 drives the transmission plate 36 to rotate through the rotating disk 31. The transmission plate 36 drives the transmission disk 35 to rotate by 90 degrees through the mutual cooperation of the transmission rod 37 and the transmission groove 38. At the same time, during the rotation of the transmission disk 35, the rotating disk 31 slides out of the inside of the arc-shaped groove 34, and the transmission disk 35 rotates into the inside of the groove 33. At the same time, the transmission disk 35 drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the connecting rod 3 and the base 4 to rotate by 90 degrees. During the rotation of the pressure rod 7, it rotates towards the direction of the charging port cover of the new energy vehicle. When the base 4 slides to the bottom of the stable pressure rod 24, through the inclined groove 23 formed at the bottom of the stable pressure rod 24, the second positioning block 22 and the power rod 15 move downward to a certain extent when sliding into the inside of the inclined groove 23. When the second positioning block 22 and the power rod 15 slide to the bottom of the stable pressure rod 24, the stable pressure rod 24 can block the second positioning block 22 and the power rod 15, making the second positioning block 22 fit more closely to the top of the charging port cover of the new energy vehicle, and the power rod 15 pushes the two first trapezoidal blocks 14 to move relatively closer through the second trapezoidal block 18, making the two first positioning blocks 10 clamp and fix the charging port cover of the new energy vehicle more stably. At the same time, under the block of the inclined groove 23, and the pressure rod 7 is closely attached to the top of the charging port cover of the new energy vehicle under the restriction of the stable pressure rod 24 and stabilizes the charging port cover of the new energy vehicle again, so that the detection and positioning of the charging port cover of the new energy vehicle are more stable. When the base 4 at the bottom of the stable pressure rod 24 rotates again after the inspection, through the release of the positioning of the pressure rod 7, the second positioning block 22 and the power rod 15 by the stable pressure rod 24, the staff can more conveniently take out the inspected charging port cover of the new energy vehicle, and through the cyclic intermittent rotation of the multiple bases 4 of the device, the detection speed of the charging port cover of the new energy vehicle by the device is increased to a certain extent.

[0045] A detection method for a charging port cover inspection tool of a new energy vehicle, comprising the following specific operation steps:

[0046] S1. When in use, after the charging port cover of the new energy vehicle is placed inside the inspection tool 5 and fixed by the staff, the staff pulls the power rod 15 upward. Through the inclined surface of the triangular block 19, the power rod 15 can push the first trapezoidal blocks 14 on the two limit frames 12 to move relatively away from each other, and the first trapezoidal blocks 14 drive the limit frames 12 to compress the spring 13. At the same time, the two limit frames 12 drive the two first positioning blocks 10 to move relatively away from each other. After the staff places the charging port cover of the new energy vehicle into the inspection tool 5, the staff releases the power rod 15, and the spring 13 drives the limit frame 12 to reset, so that the limit frame 12 can initially position and fix the charging port cover of the new energy vehicle through the first positioning block 10;

[0047] S2. Since the bottom of the second positioning block 22 is provided with an inclined surface, rubber layers are provided on both the bottom of the second positioning block 22 and the first positioning block 10. The bottom of the moving rod 21 is fixedly connected with a tension spring 20, and the bottom end of the tension spring 20 is fixedly connected with the inner wall of the first positioning block 10. The up and down movement of the moving rod 21 can compress and reset the tension spring 20, so that the charging port cover of the new energy vehicle can be protected to a certain extent during the positioning process. The second positioning block 22 can perform a certain amount of extrusion positioning on the top of the charging port cover of the new energy vehicle, making the initial installation and positioning of the charging port cover of the new energy vehicle more stable. And through the inclined surface provided at the bottom of the second positioning block 22, when the second positioning block 22 moves in the direction close to the charging port cover of the new energy vehicle, it can move upward, so that the bottom of the second positioning block 22 closely adheres to the top of the charging port cover of the new energy vehicle, and the positioning of the charging port cover of the new energy vehicle is more smooth;

[0048] S3. Start the motor 32 by the staff. The motor 32 drives the drive plate 36 to rotate through the rotating disk 31. The drive plate 36 drives the drive disk 35 to rotate 90 degrees through the mutual cooperation of the drive rod 37 and the drive groove 38. At the same time, during the rotation of the drive disk 35, the rotating disk 31 slides out of the inside of the arc groove 34, and the drive disk 35 rotates into the inside of the groove 33. At the same time, the drive disk 35 drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the connecting rod 3 and the base 4 to rotate 90 degrees. During the rotation, the pressure rod 7 rotates towards the direction of the charging port cover of the new energy vehicle. When the base 4 slides to the bottom of the stable pressure rod 24, through the inclined groove 23 opened at the bottom of the stable pressure rod 24, the second positioning block 22 and the power rod 15 move downward to a certain extent when sliding into the inside of the inclined groove 23. When the second positioning block 22 and the power rod 15 slide to the bottom of the stable pressure rod 24, the stable pressure rod 24 can block the second positioning block 22 and the power rod 15, making the second positioning block 22 fit more closely to the top of the charging port cover of the new energy vehicle, and the power rod 15 pushes the two first trapezoidal blocks 14 to move relatively closer through the second trapezoidal block 18, making the two first positioning blocks 10 clamp and fix the charging port cover of the new energy vehicle more stably;

[0049] S4. At the same time, blocked by the inclined groove 23, and restricted by the stable pressure rod 24, the pressure rod 7 closely adheres to the top of the charging port cover of the new energy vehicle and stabilizes the charging port cover of the new energy vehicle again, so that the detection and positioning of the charging port cover of the new energy vehicle are more stable. When the base 4 at the bottom of the stable pressure rod 24 rotates again after inspection, through the release of the positioning of the pressure rod 7, the second positioning block 22 and the power rod 15 by the stable pressure rod 24, the staff can more conveniently take out the inspected charging port cover of the new energy vehicle, and through the cyclic intermittent rotation of the multiple bases 4 of the device, the detection speed of the charging port cover of the new energy vehicle by the device is increased to a certain extent.

The tension spring (20) can be compressed and reset by the upward and downward movement of the moving rod (21), so that the charging port cover of the new energy vehicle can be protected to a certain extent during the positioning process. The top of the charging port cover of the new energy vehicle can be squeezed and positioned to a certain extent by the second positioning block (22), so that the initial installation positioning of the charging port cover of the new energy vehicle is more stable. The slope is provided at the bottom of the second positioning block (22), so that the second positioning block (22) can move upward when moving in the direction close to the charging port cover of the new energy vehicle, so that the bottom of the second positioning block (22) is in close contact with the top of the charging port cover of the new energy vehicle, and the positioning of the charging port cover of the new energy vehicle is smoother. S3, the staff starts the motor (32), the motor (32) drives the transmission plate (36) to rotate through the rotating disk (31), the transmission plate (36) drives the transmission disk (35) to rotate 90 degrees through the cooperation of the transmission rod (37) and the transmission groove (38), and at the same time, during the rotation of the transmission disk (35), the rotating disk (31) slides out of the interior of the arc groove (34), and the transmission disk (35) rotates into the interior of the groove (33), and at the same time, the transmission disk (35) drives the rotating shaft (2) to rotate, and the rotating shaft (2) drives the connecting rod (3) and the base (4) to rotate 90 degrees, and the pressure rod (7) rotates in the direction close to the charging port cover of the new energy vehicle during the rotation, and when the base (4) slides to the stable pressure rod During the process of sliding the second positioning block (22) and the power rod (15) to the bottom of the stabilizing pressure rod (24), the slanted groove (23) provided at the bottom of the stabilizing pressure rod (24) allows the second positioning block (22) and the power rod (15) to slide into the slanted groove (23) and move downward to a certain extent. When the second positioning block (22) and the power rod (15) slide to the bottom of the stabilizing pressure rod (24), the stabilizing pressure rod (24) can block the second positioning block (22) and the power rod (15), so that the second positioning block (22) is more closely attached to the top of the charging port cover of the new energy vehicle, and the power rod (15) pushes the two first trapezoidal blocks (14) to move relatively close to each other through the second trapezoidal block (18), so that the two first positioning blocks (10) can clamp and fix the charging port cover of the new energy vehicle more stably; S4.
