[0002] Electric vehicles refer to vehicles that use on-board power as a power source, use motors to drive the wheels, and comply with various requirements of road traffic and safety regulations. Because their impact on the environment is relatively smaller than that of traditional vehicles, their prospects are widely optimistic. As a future development trend, many universities need to learn about them. However, it is difficult for students to master theoretical knowledge alone, and practical training is needed to master practical knowledge. The existing motor drive training platform cannot simulate real scenes for experiments, which will reduce the effect of motor drive training.

[0003] According to the Chinese utility model publication number CN215987658U, a pure electric vehicle motor drive system training platform is disclosed, including a base plate and a training operation panel, the bottom of the base plate is equipped with rollers; support plates are fixed at both ends of the top surface of the base plate. It can meet the needs of actual training operations and facilitate the overall transfer to a designated place. At the same time, during training teaching and training operations, the conveniently stored guidance board can be unfolded for teaching or training operation guidance, so that it can better meet the needs of teaching. However, this setting cannot simulate real scenes for experiments, which will reduce the effect of motor drive training. Therefore, in view of this problem, how to design an electric vehicle motor drive training platform has become a problem we currently need to solve. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides an electric vehicle motor drive training platform, which is provided with a fixed arm and a mounting part, by fixing the test roller or spare roller that needs to be simulated training on one side of the mounting part, and raising the fixed arm, so that when the motor is started, the tire can be driven to rotate for real-life simulation training to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric vehicle motor drive training platform, comprising a base, a training platform body is fixedly installed on the top of the base, an adjusting screw is rotatably connected inside the training platform body, a fixed arm is threadedly connected to the outside of the adjusting screw, the fixed arm is slidably connected to the inside of the training platform body, a limit rod is fixedly installed on one side of the fixed arm, a rotating shaft is rotatably connected inside the fixed arm, a mounting piece is fixedly installed on one end of the rotating shaft, a fixing bolt is fixedly installed on one side of the mounting piece, and a test roller is slidably connected to the outside of the fixing bolt.

[0006] In a preferred embodiment, a fastening nut is threadedly connected to the outer side of the fixing bolt, the fastening nut is arranged in a close fit with the test roller, and a positioning pin is slidably connected to the interior of the limiting rod.

[0007] In a preferred embodiment, a positioning hole is opened on the outer side of the rotating shaft, the diameter of the positioning pin is smaller than the inner diameter of the positioning hole, and a pulling piece is fixedly installed on one end of the positioning pin.

[0008] In a preferred embodiment, a rotating handle is fixedly mounted on the top end of the adjusting screw, and a fixing frame is fixedly mounted on the top of the training platform body.

[0009] In a preferred embodiment, a fastening screw is slidably connected to the interior of the fixing frame, and a training motor is slidably connected to the inner side of the fixing frame.

[0010] In a preferred embodiment, the fastening screw is threadedly connected to the training motor, and a positioning column is fixedly installed inside the training platform body.

[0011] In a preferred embodiment, a spare roller is slidably connected inside the training platform body, and the spare roller is slidably connected to the outside of the positioning column.

[0012] Technical effects and advantages of the utility model:

[0013] 1. The utility model sets a fixed arm and a mounting piece. When training the motor drive, the test roller or spare roller that needs to be simulated is fixed on one side of the mounting piece. The adjusting screw is rotated by turning the handle to make the fixed arm rise. At this time, the tire is rotated by starting the training motor to simulate the scene of the tire driving on the ground, thereby achieving the purpose of the motor drive experiment;

[0014] 2. The utility model sets a limit rod and a positioning pin. When the test roller is disassembled, the positioning hole of the rotating shaft is rotated to a position where the positioning pin overlaps by rotating the test roller, and the pulling member is pushed to make the positioning pin enter the positioning hole of the rotating shaft. As a result, the rotating shaft cannot rotate when positioning the rotating shaft, thereby completing the fixation of the mounting part. At this time, no shaking or rotation will occur when the fastening nut is removed, thereby improving the disassembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0020] Refer to the instruction manual Figure 1-3 ,like Figure 1 As shown, an electric vehicle motor drive training platform according to an embodiment of the utility model comprises a base 1, a training platform body 2 is fixedly mounted on the top of the base 1, and an adjusting screw 3 is rotatably connected inside the training platform body 2, such as Figure 2 As shown, the outer side of the adjusting screw 3 is threadedly connected to a fixed arm 4, the fixed arm 4 is slidably connected to the inside of the training platform body 2, a limit rod 5 is fixedly installed on one side of the fixed arm 4, a rotating shaft 6 is rotatably connected inside the fixed arm 4, and a mounting member 7 is fixedly installed on one end of the rotating shaft 6, as shown in FIG. Figure 3 As shown, a fixing bolt 8 is fixedly installed on one side of the mounting member 7, a test roller 9 is slidably connected to the outer side of the fixing bolt 8, a fastening nut 10 is threadedly connected to the outer side of the fixing bolt 8, and the fastening nut 10 is arranged in a close fit with the test roller 9, as shown in FIG. Figure 2 As shown, a positioning pin 11 is slidably connected inside the limiting rod 5 .

[0021] It should be noted that, by placing the training motor 16 on the inner side of the fixing frame 14 and fixing the training motor 16 by a plurality of fastening screws 15, when training the motor drive, the adjusting screw 3 is rotated by turning the turning handle 13, so that the fixing arm 4 is raised, driving the test roller 9 to rise and contact the tire. At this time, the tire is rotated by starting the training motor 16, thereby simulating the scene of the tire driving on the ground, and achieving the purpose of the motor drive experiment. At the same time, by removing the test rollers 9 on both sides, the spare rollers 18 are respectively installed on one side of the mounting parts 7 on both sides. Since the surface of the spare roller 18 has uneven protrusions, it can simulate the scene of the tire driving on a bumpy ground, and then can test another driving effect of the motor, thereby realizing real-life simulation and improving the effect of motor drive training.

[0022] Further, such as Figure 2 As shown, a positioning hole is provided on the outer side of the rotating shaft 6, the diameter of the positioning pin 11 is smaller than the inner diameter of the positioning hole, and a drawing piece 12 is fixedly installed on one end of the positioning pin 11.

[0023] It should be noted that, when the test roller 9 is disassembled, the positioning hole of the rotating shaft 6 is rotated to the position where the positioning pin 11 overlaps by rotating the test roller 9, and the pulling member 12 is pushed to make the positioning pin 11 enter the positioning hole of the rotating shaft 6, so that the rotating shaft 6 cannot rotate when positioning the rotating shaft 6, thereby completing the fixation of the mounting member 7. At this time, there will be no shaking or rotation when removing the fastening nut 10, thereby improving the disassembly efficiency.
