Description

Technical Field

[0001] This invention relates to the field of battery replacement technology, specifically to a commissioning and maintenance platform for new energy container semi-trailers. Background Technology

[0002] The on-board power battery replacement, vehicle debugging, and regular maintenance of new energy container semi-trailers are specialized automated platform equipment that enables rapid energy replenishment and efficient maintenance of new energy semi-trailers. Currently, new energy container semi-trailers generally adopt the under-vehicle battery swapping mode for energy replenishment. In actual maintenance and battery swapping, the driver needs to drive the semi-trailer into a dedicated maintenance and swapping chamber, where the top mechanical claw directly grabs the battery pack installed on the exposed bottom of the frame, completing the removal of the old battery and the installation of a fully charged battery, achieving rapid battery swapping without waiting for charging.

[0003] In actual use, existing battery swapping and maintenance platforms make it difficult for drivers to park new energy container semi-trailers in a standard position parallel to the side wall of the maintenance platform, relying solely on autonomous driving. If the new energy container semi-trailer is not parallel to the side wall of the maintenance platform after parking, it means that the semi-trailer is tilted, which will directly cause the on-board battery pack to be misaligned. This makes it difficult for the mechanical claw above the maintenance platform to locate the tilted battery, resulting in problems such as gripping and positioning deviation, unstable clamping, or even failure to grip. This seriously reduces the success rate and safety of battery swapping operations and cannot meet the needs of efficient and stable battery swapping for new energy container semi-trailers. Summary of the Invention

[0040] Drive assembly 3 and power assembly 7 are used to drive the rotation of rotating assembly 2 and power assembly 7. When drive assembly 3 drives rotating assembly 2, it adjusts the distance between the semi-trailer body and the inner wall of maintenance and replacement chamber 1. When power assembly 7 drives rotating assembly 2, it adjusts the angle of the semi-trailer body in maintenance and replacement chamber 1. In and out fixing assembly 4 provides an in and out path and prevents the semi-trailer tires from getting stuck. Support assembly 5 can support measuring assembly 6 when moving. Measuring assembly 6 can measure the body angle to detect the parallelism between the semi-trailer and the inner wall of maintenance and replacement chamber 1.

[0047] In specific implementation: the second sliding constraint groove 42 provides sliding guidance and limit for the second sliding abutment wheel 44; the sliding fixing plate 43 fills the gap between the rotating entry and exit plate 21 and the entry and exit mounting plate 41 to prevent the semi-trailer tire from falling off and getting stuck; the second sliding abutment wheel 44 drives the sliding fixing plate 43 to adaptively slide and adjust with the rotation posture of the rotating component 2; the abutment mounting groove 45 is used to movably insert the support fixing frame 51 to realize the linkage and cooperation of the components; the support component 5 serves as the installation bearing and moving support structure of the measuring component 6; the support fixing frame 51, the auxiliary support column 52, the support cross plate 53 and the fixed connecting plate 55 are connected to each other to form a stable support frame; the internal threaded sleeve 54 cooperates with the threaded fixing column 73 to realize the overall horizontal movement of the support component 5; the positioning mounting plate 56 and the positioning mounting frame 57 provide precise installation positioning for the measuring component 6.

The measuring support block 61 is fixedly installed inside the positioning mounting frame 57. The measuring support block 61 is fixedly provided with the measuring connecting plate 62 at one end away from the positioning mounting plate 56. The measuring connecting plate 62 is fixedly provided with the pressure test plate 63 and two guide sleeves 64 at one end away from the measuring support block 61. The guide connecting column 65 is movably sleeved inside the guide sleeve 64. The bending pressure measuring head 67 is fixedly provided at one end of the guide connecting column 65 away from the measuring connecting plate 62. The guide spring 66 is movably provided between the bending pressure measuring head 67 and the measuring connecting plate 62.

The abutting pressure measuring block 68 is fixedly provided on the side of the bending pressure measuring head 67 near the measuring connecting plate 62. The abutting pressure measuring block 68 abuts against the pressure test plate 63.

[0049] The power assembly 7 includes a connecting limit plate 71, a third servo motor 72, a threaded fixing post 73, a second servo motor 74, a second reducer 75, and a power connecting post 76. The connecting limit plate 71 and the third servo motor 72 are fixedly installed between the power fixing plate 13 and the constraint support plate 14. The third servo motor 72 is fixedly installed on one side of the connecting limit plate 71. The threaded fixing post 73 is sleeved on the inner side of the internal threaded sleeve 54. One end of the threaded fixing post 73 is fixedly connected to the third servo motor 72.

[0050] The second reducer 75 is fixedly installed between the support connecting plate 12 and the power fixing plate 13. The second servo motor 74 is fixedly installed on the power fixing plate 13. One end of the second servo motor 74 is fixedly connected to the second reducer 75. The upper end of the second reducer 75 is fixedly provided with a power connecting column 76. The end of the power connecting column 76 away from the power fixing plate 13 is fixedly inserted into the inner side of the rotating insertion slot 26.

[0051] In practice: At the beginning of the operation, the driver drives the new energy container semi-trailer along the ground 46 into the entry and exit mounting plate 41 of the entry and exit fixed component 4, and smoothly enters the maintenance and replacement chamber 1 along the entry and exit mounting plate 41. The outer wall 11 of the maintenance and replacement chamber 1 provides a closed maintenance environment. Its inner wall is fixed from top to bottom with the support connection plate 12, the power fixing plate 13, and the constraint support plate 14, providing layered installation support for each functional component. The support connection column 15 strengthens the overall structural stability.

[0052] The rotating inlet / outlet plate 21 of the rotating assembly 2 is kept on the same horizontal plane as the inlet / outlet mounting plate 41. The sliding fixing plate 43 fills the gap between the rotating inlet / outlet plate 21 and the inlet / outlet mounting plate 41. The second sliding abutment wheel 44 at the bottom of the sliding fixing plate 43 slides along the second sliding constraint groove 42 and can be adaptively adjusted according to the posture of the rotating assembly 2, completely preventing the semi-trailer tire from falling off and getting stuck. The semi-trailer continues to drive to the surface of the semi-trailer transmission belt 28 on the body support block 22. The body limiting plate 18 of the maintenance and replacement chamber 1 restricts the lateral displacement of the body. The front limiting plate 19 limits the parking position of the front to prevent the semi-trailer from exceeding the working area. After parking and turning off the engine, the driver sends a battery replacement request command.

[0053] When the power component 7 is started, the No. 3 servo motor 72 drives the threaded fixing column 73 to rotate. The threaded fixing column 73 engages with the internal threaded sleeve 54 of the support component 5, causing the support cross plate 53, the support fixing frame 51, and the fixed connecting plate 55 to move horizontally as a whole. The auxiliary support column 52 and the support limit frame 58 improve the stability of movement, thereby causing the measuring component 6 on the positioning mounting frame 57 to move closer to the semi-trailer body.

[0054] A control cabinet is fixed between the power fixed plate 13 and the constraint support plate 14. After the driver stops the car and turns off the engine, he sends a battery replacement request command through the control terminal preset on the outside of the maintenance and replacement room 1. The command is directly transmitted to the control system integrated in the control cabinet between the power fixed plate 13 and the constraint support plate 14. The bending pressure measuring head 67 of the measuring component 6 first contacts the vehicle body. The continuous movement causes the guide connecting column 65 to retract along the guide sleeve 64, and the guide spring 66 is compressed. The pressure measuring block 68 and the pressure test plate 63 abut against each other to generate a pressure signal. The pressure test plate 63 transmits the pressure data to the control system in real time. This control system is the core control unit of the device. It can uniformly receive the battery replacement request command and the pressure detection data and accurately output the corresponding action control signal.

[0055] If the pressure signal difference detected by the two pressure test plates 63 is lower than the preset threshold, it is determined that the vehicle body is parallel to the inner wall of the maintenance and replacement chamber 1, and the battery replacement process is directly initiated. If the pressure signal difference detected by the two pressure test plates 63 exceeds the preset threshold, it is determined that the vehicle body is misaligned. The second servo motor 74 of the power component 7 is started. After the torque is reduced by the second reducer 75, the power connecting column 76 drives the body support block 22 of the rotating component 2 to rotate around the axis. The first sliding abutment wheel 27 at the bottom of the rotating entry and exit plate 21 slides smoothly along the first sliding limit groove 17 of the rotating fixed base 16 to ensure smooth rotation without jamming, until the pressure signals of the pressure test plates 63 on both sides are equal, and the vehicle body parallelism calibration is completed.

[0056] If the distance between the side of the vehicle body and the inner wall of the maintenance and replacement chamber 1 is too small after calibration, the No. 1 servo motor 33 of the drive component 3 starts, and drives the rotating connecting rod 25 to rotate through the No. 1 reducer 32, which drives the semi-trailer transmission belt 28 to rotate, finely adjust the lateral position of the semi-trailer, expand the operating space between the vehicle body and the inner wall, and after all posture adjustments are completed, the driver gets off the vehicle, releases the battery fixing constraint, and the mechanical claw on the top of the maintenance and replacement chamber 1 accurately grabs and replaces the battery, completing the entire battery swapping and maintenance operation.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention 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. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
