Description

Technical Field

[0001] This invention relates to the field of training platform technology, specifically a training platform for anti-pinch windows of new energy vehicles. Background Technology

[0002] An automotive training platform is a device specifically designed for automotive teaching, repair, and skills training. By simulating the working environment of a real automotive system, it helps students gain a deep understanding of the structure, working principles, and troubleshooting skills of various automotive systems. Among these, new energy vehicle training platforms are crucial equipment in vocational education and skills training. Currently, mainstream products can be divided into two main categories: drivetrain system training platforms and full vehicle electrical system training platforms, focusing on the teaching needs of powertrain systems and low-voltage electrical systems, respectively.

[0003] The anti-pinch window mechanism in new energy vehicles uses a Hall effect sensor to monitor the motor speed in real time. When an object gets caught in the window, causing a change in motor speed, the ECU immediately commands the motor to reverse, retracting the window and thus achieving the anti-pinch function. However, existing training platforms are lagging behind in technology updates. Many core components are based on traditional vehicle models, making it difficult to keep up with new energy vehicle technologies. They lack the ability to simulate or demonstrate the working principle and troubleshooting of the anti-pinch window function, preventing students from translating theoretical knowledge learned in the classroom into practical skills. This results in a disconnect between teaching content and industry development. Summary of the Invention

[0027] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Please see Figures 1 to 11 As shown in the embodiment of this application, a training platform for anti-pinch windows of new energy vehicles is provided, including a frame 1 and a door 2 fixed on the frame 1. The door 2 adopts a half-section structure. An anti-pinch simulation mechanism is provided at the rear end of the frame 1. The anti-pinch simulation mechanism includes an n-shaped mounting plate 3, a servo cylinder 4, a push plate 5, a flipping block 6, a servo cylinder 7, a push plate 8, a three-jaw clamping structure, and an anti-pinch tester 9. The n-shaped mounting plate 3 is installed at the rear end of the frame 1. The bottom of the servo cylinder 4 is hinged to the left side of the n-shaped mounting plate 3. The two ends of the push plate 5 are movably inserted into the top of the n-shaped mounting plate 3 through rotating shafts. The flipping block 6 is connected to the left end of the push plate 5 and is hinged to the telescopic end of the servo cylinder 4. The servo cylinder 7 is fixedly embedded in the center of the push plate 6. The push plate 8 is installed on the telescopic end of the servo cylinder 7. The three-jaw clamping structure is installed on the push plate 8. The rear end of the anti-pinch tester 9 is clamped on the three-jaw clamping structure. A glass lifting mechanism is provided inside the door 2.

[0029] In this embodiment, the anti-pinch tester 9 is clamped at the rear end of a three-jaw clamping structure, which is detachable. Other items, such as mineral water bottles, can also be clamped on the three-jaw clamping structure to simulate obstacles. The anti-pinch tester 9 works by simulating the reactions of different parts of the human body when subjected to pressure to evaluate the performance of the anti-pinch system. As an existing product, during the simulated anti-pinch demonstration of the car window, the extension end of servo cylinder 4 extends, driving push plate 5 to rotate to a horizontal position via flipping block 6. Then, the extension end of servo cylinder 7 extends, causing the front end of the anti-pinch tester 9 on push plate 8 to extend into the car window of door 2. Figure 1 As shown, the window lifting mechanism can raise and lower the car window glass. When the car window glass encounters the anti-pinch tester 9, causing a change in rotation speed, the ECU immediately commands the motor to reverse, realizing the retraction of the car window glass. This dynamically simulates and demonstrates the working principle and troubleshooting of the anti-pinch function of the car window. The anti-pinch tester 9 can display the pressure generated. Students can transform the theoretical knowledge learned in class into practical skills, thereby better mastering automotive-related system knowledge and skills, improving practical ability and professional qualities, and meeting the needs of automotive vocational education.

[0030] In some embodiments, the three-jaw clamping structure includes a base plate 10, three fixed slide rails 11, three sliding rods 12, three conical clamping heads 13, a threaded sleeve 14, and a threaded rod 15. The base plate 10 is installed at the front end of the push plate 8. The three fixed slide rails 11 are evenly installed on the base plate 10. The rear ends of the three sliding rods 12 are movably inserted into the three fixed slide rails 11. The three conical clamping heads 13 are installed at the front ends of the three sliding rods 12. The threaded sleeve 14 is fixed to the upper end of the base plate 10. The threaded rod 15 is threadedly inserted into the threaded sleeve 14, and its bottom is movably connected to the top of one of the sliding rods 12. A triangular plate 16 is movably installed at the center of the base plate 10, and three sliding rods 12 are respectively hinged to the triangular plate 16 through connecting rods 17.

[0031] As shown in Figure 5, the trainee rotates the threaded rod 15 clockwise to drive the top sliding rod 12 downward, and through the rotation of the three connecting rods 17 and the triangular plate 16, drives the other two sliding rods 12 to move synchronously, so that the three conical clamping heads 13 can clamp the anti-crushing tester 9 or other items. Conversely, the trainee can release the anti-crushing tester 9 through the three conical clamping heads 13 by rotating the threaded rod 15 counterclockwise.

[0032] In some embodiments, the window lifting mechanism includes a motor 18, a set of slide rails 19, a rope system 20, a set of bracket assemblies 21, a window glass 22, and a position sensor 23.

A Hall sensor 24 is installed on the electric motor 18.

[0033] and combined Figure 2 As shown, the rope system 20 includes a steel wire rope and a pulley. The steel wire rope is wound around the pulley. The motor 18 drives the power source, and after being reduced in speed by the reducer, the output power is transmitted to the steel wire rope. The steel wire rope winds or unwinds on the pulley, thereby pulling or releasing a set of bracket assemblies 21. The window glass 22 is mounted on a set of bracket assemblies 21. As the steel wire rope moves, the set of bracket assemblies 21 moves up and down on a set of slide rails 19, ultimately completing the lifting and lowering operation of the window glass 22. The position sensor 23 is a contact sensor. When the window glass 22 moves to the bottom, the position sensor 23 receives a signal to control the opening and closing of the anti-pinch simulation mechanism. The anti-pinch simulation mechanism and the window glass 22 prevent interference. The Hall sensor 24 is used to detect the speed of the motor 18, thereby realizing the position recognition and anti-pinch function of the window glass 22.

[0034] In some embodiments, the door 2 is fixed to the frame 1 by a rotating locking mechanism; the rotating locking mechanism includes a strip rail 25, a fixed seat 26, a cover plate 27, a handle 28, a sliding seat 29, a set of connecting shafts 30, a push rod 31, a first spring 32, several rubber buffer pads 33, a set of hinge seats 34, a set of round rods 35, a set of locking plates 36, a set of locking screws 37, a second spring 38, and a set of locking nuts 39.

[0035] and combined Figure 7 — Figure 10 As shown, the car door 2 is hinged to the fixed seat 26 and the sliding seat 29 via a set of connecting shafts 30 on the left side, allowing it to be flipped for easy teaching demonstrations. The top rod 31 supports the sliding seat 29, and the sliding seat 29, together with the top rod 31 and spring 32, provides a buffering effect, facilitating the maintenance and replacement of the car door 2. By rotating the cover plate 27 through the handle 28, the cover plate 27 covers the top of the upper connecting shaft 30, preventing the car door 2 from falling off when it rotates. Several rubber buffer pads 33 provide a buffering effect for the car door 2, preventing collisions when the car door 2 is flipped. A set of locking plates 36 is used to fix the right side of the car door 2. When locked, a set of springs 38 provides a buffering effect. By loosening a set of locking nuts 39 and pulling the set of locking plates 36 to the right, the set of locking plates 36 can be detached from the car door 2, facilitating the rotation of the car door 2. Rubber pads are respectively provided at the bottom front end of the cover plate 27 and the set of locking plates 36.
