[0003] A search revealed a Chinese patent publication number, CN218455775U, which discloses a new energy motor test bench, belonging to the field of motor testing technology. The bench includes a processing table with a vertical plate fixedly connected to its upper surface; a testing mechanism; the testing mechanism includes a timer fixedly installed on one side of the vertical plate; and a hollow round rod. By setting the timer above the processing table, the operating time of the motor under high-speed rotation can be tested to determine the motor's lifespan. The rotatable hollow round rod, along with an infrared sensor installed on one side of the vertical plate, allows for testing the number of rotations of the motor to meet usage requirements.

[0004] Although the aforementioned patent can test the number of rotations of an electric motor, the aforementioned device still has the following problems: since the infrared sensor of the device is directly exposed to the external environment, when the device is not in use, objects in the external environment are prone to colliding with the infrared sensor, causing damage to the infrared sensor and reducing its service life. In order to address the above situation, technological innovation is carried out on the basis of the existing device. Utility Model Content

[0024] Please see Figure 1-6This utility model provides a technical solution: a test bench for a new energy motor, including a test bench 1. The test bench 1 has a movable groove 2 extending to the outside of the test bench 1. A threaded rod 11 extending to the outside of the test bench 1 is rotatably connected inside the movable groove 2. Two symmetrical movable frames 3 are slidably connected inside the movable groove 2. A fixing plate 4 is fixedly connected to the top of each of the two movable frames 3, allowing the new energy motor to be clamped and fixed. A support frame 5 is fixedly connected to the top of the test bench 1, located to the left of the fixing plate 4. A round rod 7 is rotatably connected to one side of the support frame 5. The round rod 7 has a hollow interior. An infrared sensor is located on one side of the support frame 5. The device is located on the front side of the round rod 7. The infrared sensor has an existing structure, which will not be described in detail here. A sliding groove 20 is opened on the outer surface of the round rod 7. A sliding block 21 is slidably connected inside the sliding groove 20. A protective frame 8 is fixedly connected to the side of the sliding block 21 away from the sliding groove 20. The protective frame 8 can protect the infrared sensor. A tension spring 19 is fixedly connected to one side of the sliding block 21. The end of the tension spring 19 away from the sliding block 21 is fixedly connected to the inner wall of the sliding groove 20. The movement of the sliding block 21 can stretch and reset the tension spring 19. A baffle 17 is rotatably connected inside the protective frame 8. The baffle 17 can make the infrared sensor more smoothly detect the number of rotations of the protective frame 8.

[0025] The baffle 17 is rotatably connected to the inside of the protective frame 8 via a shaft. A torsion spring 18 is fixedly connected to one side of the baffle 17 and movably sleeved on the shaft. The end of the torsion spring 18 away from the baffle 17 is fixedly connected to the inner wall of the protective frame 8. The torsion spring 18 can be compressed and reset by rotating the baffle 17.

[0026] A protective rod 9 is fixedly connected to the side of the support frame 5 near the round rod 7. The protective rod 9 is positioned above the infrared sensor. The protective rod 9 can block the baffle 17, so that when the protective frame 8 resets to protect the infrared sensor, the protective rod 9 first contacts the baffle 17, causing the baffle 17 to rotate. This reduces the possibility of the baffle 17 damaging the infrared sensor when the protective frame 8 resets, thus allowing the infrared sensor to be protected more effectively.

[0027] The surface of the threaded rod 11 has two opposite threads starting from its center. Two movable frames 3 are respectively set on the two opposite threads of the threaded rod 11. When the operator rotates the threaded rod 11, the threaded rod 11 can drive the two movable frames 3 to move relative to each other under the restriction of the limiting groove 12, so that the output end of the new energy motor can always be kept in a straight line with the round rod 7, thus making the fixing of the new energy motor more convenient.

[0028] A limiting ring 6 is fixedly connected to the side of the support frame 5 near the round rod 7. The round rod 7 is located inside the limiting ring 6. A limiting movement groove 22 is opened on the outer surface of the limiting ring 6. The movement direction of the protective frame 8 can be limited by the limiting movement groove 22.

[0029] The round rod 7 has two symmetrical limiting grooves 12 inside. A support plate 14 is slidably connected inside the round rod 7. A limiting block 15 is slidably connected inside the limiting groove 12 and fixedly connected to the surface of the support plate 14. The movement direction of the support plate 14 is restricted by the limiting block 15. A spring 13 is fixedly connected to one side of the support plate 14. The end of the spring 13 away from the support plate 14 is fixedly connected to the inner wall of the round rod 7. The movement of the support plate 14 can compress and reset the spring 13.

[0030] A pull rope 10 is fixedly connected to the side of the protective frame 8 away from the baffle 17. The end of the pull rope 10 away from the protective frame 8 is fixedly connected to the surface of the limiting block 15. As the output shaft of the motor slides into the round rod 7, it pushes the support plate 14 to move. The support plate 14, through the limiting block 15 and the pull rope 10, drives the protective frame 8 to move, exposing the infrared sensor. This allows the infrared sensor to detect the number of rotations of the motor. After the motor detection is completed, the operator rotates the protective frame 8 to the limiting movement groove 22 and then slides the output end of the detection motor out of the round rod 7. The tension spring 19 and spring 13 reset the frame, causing the tension spring 19 to drive the protective frame 8 to move closer to the protective rod 9. This allows the protective frame 8 to be fitted onto the infrared sensor, protecting it and reducing its direct exposure to the external environment when not in use. This prevents objects in the external environment from colliding with the infrared sensor, causing damage and reducing its lifespan.

[0031] The limiting groove 12 is rotatably connected to a rotating shaft 16. The surface of the pull rope 10 is connected to the surface of the rotating shaft 16. Through the cooperation between the pull rope 10 and the rotating shaft 16, the friction of the pull rope 10 at the end of the round rod 7 is reduced to a certain extent, and the service life of the pull rope 10 is extended to a certain extent.

[0032] Working Principle: For this type of test bench for new energy motors, the operator first slides the output end of the new energy motor to be tested into a certain position inside the round rod 7. Then, the output end of the motor is fixed to the round rod 7 with bolts. The operator then rotates the threaded rod 11, which, under the constraint of the limiting groove 12, drives the two moving frames 3 to move relative to each other, ensuring that the output end of the new energy motor remains aligned with the round rod 7. This makes fixing the new energy motor more convenient. By pushing the support plate 14, the support plate 14 moves the protective frame 8 through the limiting block 15 and the pull rope 10, exposing the infrared sensor and allowing the infrared light to pass through. The sensor can detect the number of rotations of the motor. After the motor is detected, the operator rotates the protective frame 8 to the limit movement groove 22, and then the operator slides the output end of the detection motor out of the round rod 7. The tension spring 19 and spring 13 reset the frame, and the tension spring 19 drives the protective frame 8 to move closer to the protective rod 9. The protective frame 8 can then be fitted onto the infrared sensor, thus protecting the infrared sensor. This reduces the direct exposure of the infrared sensor to the external environment when it is not in use, preventing objects in the external environment from colliding with the infrared sensor and causing damage, which would reduce the lifespan of the infrared sensor.
