Through systematic learning, students can fully master the basic knowledge and skills of new energy vehicles, laying a solid foundation for future work in the research and development, manufacturing, sales, and maintenance of new energy vehicles.

[0003] The application of various new technologies at this stage has brought a better teaching experience for interactive teaching of new energy vehicles. Especially with the popularization and application of VR technology, students can see digital models by wearing VR glasses, and cooperate with tracking devices that may be installed around the classroom or on the ceiling to track the positions and movements of multiple students. The virtual environment can display three-dimensional models, realize model observation, explosion decomposition, and principle animation. However, teaching through VR technology still has the following disadvantages: 1. During the VR technology display process, the tracking device needs to maintain an open field of view. When students enter the cab, the signal transmission of the tracking device is blocked by the vehicle body, which interferes with the three-dimensional model display process.

[0004] 2. When the tracking device is installed on the ceiling, the field of view can be expanded by removing the roof, but the accelerator and brake are relatively hidden, which is not convenient for students to operate in the VR environment. Summary of the invention

[0015] A green and intelligent new energy vehicle teaching interactive playback method comprises the following steps: Step 1: Wear the VR headset on your head and the controller on your hand. Check the VR headset and controller by flexing and extending your hand to determine whether the controller fits your hand. Also, check the VR headset and controller through external language guidance. Step 2: Start the processing host, tracking device, and VR head display device. The VR head display device projects a preset three-dimensional model of the new energy vehicle on the eyes. The tracking device tracks the movement of the head and updates the display content in real time. The three-dimensional model of the new energy vehicle is demonstrated and interacted on the outside of the vehicle body. Step 3: Enter the vehicle body and sit on the seat to interact with the 3D model of the new energy vehicle. Use your hands to touch the steering wheel model, brake pedal model, main control screen model, ignition button model, warning light button model, air conditioning button model, or use your feet to step on the accelerator pedal model and shift lever model. Step 4: contacting the model, contacting the first triggering element, the second triggering element or the third triggering element, triggering an in-position signal, and transmitting the in-position signal to the VR simulation environment to maintain the evolution process of the three-dimensional model; Step 5: The head movement is captured in real time by a tracking device.

[0016] The technical effects achieved by the present invention are: The present invention instructs students to enter the cab and independently operate various models in the cab. During the touching process, the students touch the first trigger, the second trigger or the third trigger to trigger an arrival signal, and the arrival signal is transmitted to the VR simulation environment to overcome the shielding effect of the vehicle body and maintain the evolution process of the three-dimensional model. In addition, the head movements of the students are captured in real time through the tracking device. When the head movements deviate from the specified model range, the airflow is used to impact the students' hands to punish their wrong operations or distracted states, and remind the students to return to the teaching interaction state. In addition, the airflow is used to take away the heat of the first trigger, the second trigger or the third trigger to prevent them from overheating and causing malfunctions.

[0017] The present invention utilizes an inclined pedal to guide the foot to the height where the brake pedal model and the accelerator pedal model are located, and guides the foot to the third triggering member by stepping on the pedal, so that the rubber sheet scrapes off the dust on the sole through friction, and increases the friction between the foot and the pedal through the rubber bristle belt to maintain a sufficiently large friction surface to peel off the dust on the sole. In the process of stepping on the foot, a safe distance is reserved through the notch, and when the foot leaves, the arc-shaped rubber sheet adhered to the back of the pedal rebounds, pushing the pedal to reset, and re-attaching to the brake pedal model and the accelerator pedal model, so as to facilitate service for subsequent students.

[0018] The present invention utilizes a thermally conductive film made of silicone material to transfer the heat of the hand to the temperature-variable resistor of the first trigger component. In order to prevent the temperature-variable resistor from overheating, the heat of the first trigger component is absorbed by a phase-change material sheet. When the temperature rises to 36°C, the phase-change material sheet deforms and softens and falls from the heat dissipation hole. While falling, the heat dissipation hole can be opened to dissipate heat for the first trigger component, thereby ensuring airflow to dissipate heat for the temperature-variable resistor, and the heat insulation cover can slow down the heat loss of the thermally conductive film while circumferentially protecting the temperature-variable resistor to prevent bumps.

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0022] New energy vehicle teaching interactive playback system is usually built based on advanced technologies such as virtual reality (VR) and mixed reality (MR), and provides students with an immersive learning experience by simulating the real working environment and fault scenarios of new energy vehicles. The system can interactively play teaching content in real time, including the display of the internal structure of the vehicle, explanation of the working principle, fault diagnosis and troubleshooting, etc., so that students can perform practical operations in a virtual environment and deepen their understanding and mastery of new energy vehicle technology.

[0023] In particular, the use of VR technology directly avoids the high-voltage electrical environment in the teaching process, so that students do not have to operate the various components of new energy vehicles with electricity, or conduct various technical drills with electricity, which greatly improves the safety of the teaching environment.

[0024] Embodiment 1: like Figure 1-Figure 10 As shown, a green and intelligent new energy vehicle teaching interactive playback system includes a processing host, a vehicle body 2, and a heat shield 3. An independent computer host can be configured in a computer room as the processing host. The processing host is connected to a VR head display device 1 and a tracking device through a WIFI signal. The campus 5G network can be used to improve signal transmission efficiency. The tracking device is connected to a controller for wearing on the limbs, such as special gloves. After the students wear the VR head display device 1 and the controller, the tracking device tracks the movements of the limbs, which is convenient for the students to operate or view the three-dimensional model outside the vehicle body 2. At the same time, a cab and a penetration are provided inside the vehicle body 2. The air supply mechanism of the cab is equipped with a steering wheel model, a brake pedal model, an accelerator pedal model, a shift lever model, a main control screen model, an ignition button model, a warning light button model, and an air conditioning button model. The main control screen model is surrounded by a heat insulation cover 3 made of aluminum alloy. After entering the vehicle body 2, students can touch these models and interact with them in real life, enriching the classroom teaching experience and deepening their impressions. They can also feed back the touch actions to the virtual environment of the VR head display device 1 and interact synchronously with the three-dimensional model, such as showing the ignition, failure, braking, and air conditioning switch of new energy vehicles, as well as brightly displaying the corresponding vehicle parts in the three-dimensional model.

[0025] See attached Figure 1 , Figure 3 and Figure 5, the above models will be blocked by the vehicle body 2 and cannot be captured by the tracking device, requiring another signal transmission method. In this embodiment, the first trigger member 201, the second trigger member 202 and the third trigger member 203 connected to the processing host are bonded to the cab interval. The teacher can enter the cab through a preset program or personally direct the students to operate the above models independently. During the touch process, the first trigger member 201, the second trigger member 202 or the third trigger member 203 is touched to trigger the in-place signal, and the in-place signal is transmitted to the VR simulation environment to overcome the blocking effect of the vehicle body 2 and maintain the evolution process of the three-dimensional model. In addition, the student's head movement is captured in real time through the tracking device. When the head movement deviates from the specified model range, the first trigger member 201 is bonded with a trigger member connected to the processing host. The first air outlet piece 204 connected to the air supply mechanism has a function of blowing air when the first trigger piece 201 is triggered, or the second air outlet piece 205 connected to the air supply mechanism is bonded to the second trigger piece 202, and the second air outlet piece 205 is used to blow air when the second trigger piece 202 is triggered, or the third air outlet piece 206 connected to the air supply mechanism is bonded to the third trigger piece 203, and the third air outlet piece 206 is used to blow air when the third trigger piece 203 is triggered. The airflow is used to impact the student's hands to punish his wrong operation or distraction state, reminding the student to return to the teaching interaction state, and the airflow is used to take away the heat of the first trigger piece 201, the second trigger piece 202 or the third trigger piece 203 to prevent them from overheating and causing malfunctions.

[0026] Furthermore, the first trigger component 201 can be installed on the main control screen model using multiple temperature-variable resistors in series, especially for the area of ​​the main control screen model. The number of temperature-variable resistors in series can be set to 36, 48, etc. Once the heat from the student's hand is received, the electrical signal will change. The second trigger component 202 and the third trigger component 203 can both use the GML670 model human body weighing sensor. One second trigger component 202 and a second air outlet component 205 are installed on the shift lever model, so that students can squeeze the second trigger component 202 when holding the shift lever model to trigger an in-place signal. Three third trigger components 203 are installed on the steering wheel model, and five third trigger components 203 are installed on the brake pedal model, the accelerator pedal model, the ignition button model, the warning light button model, and the air conditioning button model, so that when students touch these models, they can squeeze the third trigger component 203 to trigger an in-place signal, thereby indicating that the action inside the vehicle body 2 is in place, and linking the action to the VR simulation environment.

[0027] See attached Figure 1 and Figure 2In order to facilitate students to enter the cab for interaction, in this embodiment, a seat 21, a hook 22 bonded to the back of the seat 21, and a back pocket 23 are fixed inside the cab by bolts. The hook 22 is used to hang the VR head display device 1, which can separate the VR head display device 1 from the first trigger member 201, the second trigger member 202 and the third trigger member 203, so that it can be taken when needed, and the controller can be put into the back pocket 23 for easy access.

[0028] Students wear the VR head display device 1 on their heads, which puts their eyes in a sealed environment, making it difficult to dissipate heat, causing sweating over time, or generating water mist to blur their vision, hindering the teaching interaction.

[0029] See attached Figure 1 and Figure 4 In order to prevent water mist, the present embodiment installs an exhaust pipe 19 and a sweat-absorbing belt 20 on the VR head display device 1. The exhaust pipe 19 connects the VR head display device 1 with the external environment to evaporate moisture, and the sweat-absorbing belt 20 is used to absorb facial sweat. The sweat-absorbing belt 20 is made of ice silk material that absorbs sweat and dissipates heat, so as to keep the inside of the VR head display device 1 dry and prevent water mist from obstructing the line of sight.

[0030] After the various models are combined with VR technology, the consumption of various electric energy of new energy vehicles in the teaching process is directly reduced, which reflects the concept of green teaching. The airflow used for the trigger signal needs to be timely and accurate. The use of airflow is inseparable from intelligent control technology, especially the application of industrial control computers. Combined with the pre-set program of the teacher, the first air outlet 204, the second air outlet 205 or the third air outlet 206 can be used to discharge air at a fixed point.

[0031] See attached Figure 1 and Figure 3 Therefore, the air supply mechanism of this embodiment includes a single-chip microcomputer 7 arranged inside the vehicle body 2, an air pump 8 connected to the single-chip microcomputer 7, a splitter 9 connected to the output end of the air pump 8, and an electric valve 10 installed at the air outlet of the splitter 9. One end of the electric valve 10 is connected to the connecting pipe 209. When the punishment signal is triggered or the temperature is lowered, the electric valve 10 is opened by controlling the single-chip microcomputer 7, and the corresponding connecting pipe 209 is in an unobstructed state. The clean air of the air-conditioning system is sucked through the air pump 8, so that the air pump 8 supplies air to the first air outlet piece 204, the second air outlet piece 205 or the third air outlet piece 206, so that air can be accurately discharged at each model.

[0032] Among them, the single-chip microcomputer 7 and the processing host can use network cables, RS485 interfaces or 5G networks for signal connection, so as to realize the interconnection between each trigger signal and the VR environment, and ensure the smoothness of the action linkage to the VR simulation environment. Among them, the wired connection method or the 5G network connection method is used, and the reliability of data parallelism is high, especially when there are many online users, it can still run stably, which is beneficial to the classroom quality of interactive playback of new energy vehicle teaching.

[0033] See attached Figure 1 , Fig. 9 and Fig.10 The students' eyes are covered and they cannot directly see where their feet reach the cab. For this reason, a pedal 4 staggered from the third trigger member 203 is hinged on the lower wall of the cab. The foot is guided to the height of the brake pedal model and the accelerator pedal model by the inclined pedal 4. The foot is guided to the third trigger member 203 by the pedal 4, so that the rubber sheet 5 scrapes off the dust on the sole through friction. In the process of stepping on the foot, a safety distance is left by opening a notch 6 surrounding the third trigger member 203 on one side of the pedal 4, so that the foot drives the pedal 4 to flip downward. When the foot leaves, the arc-shaped rubber sheet 5 bonded to the back of the pedal 4 rebounds, pushing the pedal 4 to reset and re-attach to the brake pedal model and the accelerator pedal model, so as to facilitate service for subsequent students.

[0034] See attached Figure 1 , Fig. 9 and Fig.10 The effect of using the pedal 4 alone may not be obvious enough, especially after being stepped on many times, the wear is obvious. Therefore, in this embodiment, a connecting rubber strip 14 is bonded between one side of the pedal 4 and the inner wall of the cab. The connecting rubber strip 14 can be bent repeatedly as a link without breaking. A rubber bristle strip 15 staggered with the notch 6 is bonded to the surface of the pedal 4. The rubber bristle strip 15 increases the friction between the foot and the pedal 4 to maintain a sufficiently large friction surface to peel off the dust on the sole. A latex edging 16 is bonded to the edge of the notch 6, so that when the pedal 4 is reset, the deformation of the edging 16 can buffer its impact relative to the brake pedal model and the accelerator pedal model, thereby reducing noise.

[0035] See attached Figure 1 , Figure 5 and Figure 6 The student's hand is wearing a glove-shaped controller, which hinders heat dissipation and is prone to heat. In this embodiment, the first trigger member 201 is embedded in the heat insulation cover 3, and a heat-conducting film 301 and a grid line 302 fixedly connected to the back of the heat-conducting film 301 are fixed at the opening of the heat insulation cover 3. The heat-conducting film 301 made of silicone material is used to transfer the heat of the hand to the temperature-variable resistor of the first trigger member 201. In order to prevent the temperature-variable resistor from overheating, a heat dissipation hole 303 facing the first trigger member 201 and a phase change material sheet 304 embedded in the heat dissipation hole 303 are provided on the back of the heat insulation cover 3. The heat of the first trigger member 201 is absorbed by the phase change material sheet 304. When the temperature rises to 36°C, the phase change material sheet 304 is deformed and softened and falls from the heat dissipation hole 303. At the same time, the heat dissipation hole 303 can be opened to dissipate heat for the first trigger member 201, thereby ensuring that there is airflow to dissipate heat for the temperature-variable resistor, and the heat insulation cover 3 can protect the temperature-variable resistor circumferentially while slowing down the heat loss of the heat-conducting film 301 to prevent collision.

[0036] The phase change material 304 includes calcium chloride hexahydrate, strontium chloride hexahydrate, maleic anhydride, sodium formate, sodium chloride, potassium persulfate and water in a mass ratio of 25:20:10:8:8:2:27. The phase change temperature limit is 36°C, and the phase change process is reversible.

[0037] Furthermore, the air outlet of the first air outlet piece 204 passes upward through the heat conductive film 301 close to the side of the steering wheel model, and multiple first air outlet pieces 204 are arranged in a straight line array, for example, the first air outlet pieces 204 are set to 8, so as to cover as many students' arms as possible without blocking the cables, to prevent the students' arms from being offset when the air is discharged.

[0038] See attached Figure 1 , Figure 3 and Figure 7 One end of the second air outlet piece 205 is ring-shaped and a plurality of air outlet nozzles 207 are passed through the ring. The air outlet nozzles 207 can be set to at least 8, with a wider air outlet area, which can radiate to the hands of students. One end of the third air outlet piece 206 is ring-shaped and a wind guide duct 208 is passed through the ring. Air is blown through the air outlet nozzles 207 or the air guide duct 208 to make the air flow impact the hands to warn and correct. The first air outlet piece 204, the second air outlet piece 205 and the third air outlet piece 206 are all connected to a connecting pipe 209 connected to the air supply mechanism, so that the connecting pipe 209 supplies air to the air outlet nozzles 207.

[0039] See attached Figure 1 , Figure 2 and Figure 3 During the punishment process, the airflow can be easily avoided by students, and other measures need to be adopted to implement the punishment action. Therefore, in this embodiment, a bent pipe 11 is installed at one end of the electric valve 10, and the bent pipe 11 is used to divert the wind of the air pump 8. One end of the bent pipe 11 is extended to the bottom of the cab and the end is connected to a compressed air outlet head 12. A bracket 13 connected to the inner wall of the vehicle body 2 is installed on the outside of the bent pipe 11 for tightening. When an alarm is given, the compressed air outlet head 12 is intermittently discharged to make the air flow impact the cab to form vibration and punish the students.

[0040] See attached Figure 1 The disciplinary action can effectively remind students, but it may not be obvious enough for teachers. Therefore, an indicator light strip 17 and a buzzer 18 connected to the signal of the single-chip microcomputer 7 are fixed on the outer surface of the vehicle body 2. When warning, the single-chip microcomputer 7 controls the indicator light strip 17 to emit light and controls the buzzer 18 to emit sound, which is used for sound and light warning, making it convenient for teachers to grasp the teaching interaction status of students in time.

[0041] Embodiment 2: In order to standardize students' interactive actions using VR technology during the teaching process of new energy vehicles, especially since the three-dimensional model of new energy vehicles is relatively complex and difficult for students to quickly master and understand, teachers need to help students based on their own knowledge and experience. This embodiment provides constructive method guidance for the green and intelligent new energy vehicle teaching interactive playback system mentioned in Example 1, but does not limit the improvement of its use method.

[0042] like Figure 1-Figure 11 As shown, a green and intelligent new energy vehicle teaching interactive playback method includes the following steps: Step 1: The student wears the VR head display device 1 on the head and the controller on the hand. By flexing and extending the hand, the controller is judged to fit the hand. The VR head display device 1 and the controller are checked through external language guidance. After the teacher guides the student to wear them correctly, the new energy vehicle teaching can begin. Step 2: Start the processing host, tracking device, and VR head display device 1. The VR head display device 1 projects a preset three-dimensional model of the new energy vehicle on the eyes. The tracking device tracks the movement of the head and updates the display content in real time. Students demonstrate and interact with the three-dimensional model of the new energy vehicle outside the vehicle body 2, such as showing the ignition, failure, braking, and air conditioning of the new energy vehicle, and brightly displaying the corresponding vehicle parts in the three-dimensional model. Step 3: The student enters the vehicle body 2 and sits on the seat 21 to interact with the new energy vehicle 3D model by touching the steering wheel model, brake pedal model, main control screen model, ignition button model, warning light button model, air conditioning button model with his hands, or steps on the accelerator pedal model and the shift lever model with his feet; Step 4: The student touches the model, touches the first trigger element 201, the second trigger element 202 or the third trigger element 203, triggers the in-position signal, and transmits the in-position signal to the VR simulation environment to overcome the occlusion effect of the vehicle body 2 and maintain the evolution process of the three-dimensional model; Step 5: The student's head movement is captured in real time through the tracking device. When the head movement deviates from the specified model range, the first air outlet 204, the second air outlet 205 or the third air outlet 206 blows air, and uses the airflow to impact the student's hands to punish the student's wrong operation or distraction, and remind the student to return to the teaching interaction state. In this way, the teaching using the new energy vehicle teaching interactive playback system in Example 1 is highly intelligent, and the airflows are used to take away the heat of the first trigger 201, the second trigger 202 or the third trigger 203 to prevent them from overheating and causing malfunctions.

[0043] The above is only an optional implementation of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
