Description

Technical Field

[0001] The present invention relates to the field of new energy vehicle teaching, and in particular to a multi-station training platform for a new energy high voltage system. Background Art

[0002] With the development of battery technology, economical and environmentally friendly new energy vehicles are becoming more and more common. In order to make users worry-free when using them, the automotive industry needs a large number of professional and skilled personnel with new energy technology to participate in the after-sales maintenance and repair of new energy vehicles. However, while new energy vehicles give users enjoyment, they also bring huge challenges. It increases the learning difficulty of professional and skilled personnel. It is not only about how to operate and repair simply, but also requires mastering solid theoretical knowledge. Only by using theoretical knowledge as a basis can we gain an advantage in after-sales maintenance. However, the current targeted teaching system is still in short supply and has some shortcomings. For example, the existing teaching and training platform for new energy vehicles generally raises the car, and then teachers and students look up to observe and teach the bottom structure of the car, such as the chassis. This method is not intuitive enough, and the teaching effect is relatively poor, which needs to be improved. In addition, the existing traditional whole vehicle teaching has the following disadvantages: the whole vehicle teaching and learning space will be very limited, which is not convenient for group teaching; although the whole vehicle teaching is practical, multi-person teaching will not be intuitive enough and is not convenient for demonstration teaching; even if there are multiple whole vehicles for group teaching, teachers cannot take into account the guidance of several workstations.

[0003] Based on the above, the present invention proposes a new energy high-voltage system multi-station training platform. Summary of the invention

[0004] In order to solve the problems mentioned in the above background, the present invention provides a new energy high-voltage system multi-station training platform.

The whole vehicle display mechanism includes a display platform. A top seat is respectively arranged at both ends of the display platform. Initially, the upper surface of the top seat is flush with the upper surface of the display platform. A connecting shaft is installed at the middle position of the two top seats facing each other through a bearing.

Hinge point 1 is located at the middle position of lower connecting rod 1 or lower connecting rod 2. The bottoms of the two lower connecting rods are respectively hingedly connected with the two lower slide seats.

[0018] Two upper connecting rods are provided, namely, upper connecting rod 1 and upper connecting rod 2.

[0023] Furthermore, in the second mode, the process in which the driving component drives the connecting shaft to rotate so as to deflect the new energy vehicle includes:

[0024] Step 1: When the two lower slide seats are driven to move toward each other by hydraulic technology, the two upper slide seats can be driven to move toward each other by the scissor-type connection assembly, thereby driving the top seat to move upward;

[0025] Step 2: While step 1 is occurring, the scissor-type connection assembly, the upper auxiliary rod and the lower auxiliary rod cooperate with each other to drive the connection shaft to rotate and rotate with the frame, thereby deflecting the car.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. One of the core points of this solution is that it has a teaching platform and multiple group measurement platforms, and both the teaching platform and the group measurement platform are equipped with a universal fault manual setting platform. With the high-definition projection and touch screen installed on the teaching platform, it can intuitively display teaching PPT, video materials and real-time operation demonstrations to the college, enhance the intuitiveness and interactivity of teaching, and facilitate group multi-person teaching;

[0028] The general fault manual setting platform adopts an integrated design and can simulate various electrical faults, including open circuit, short circuit, poor contact, signal abnormality, etc. It adopts programmable control and introduces a programmable controller (PLC) or microprocessor to realize the automation and intelligence of fault setting, support preset fault sequences and random fault generation, and improve the flexibility and fun of teaching.

[0029] 2. Another core of this solution lies in the driving component of the second method: although the rotation angle of the connecting shaft of the second method is limited by the scissors-type connection assembly and can only rotate between 0-90 degrees, it is enough to expose the bottom of the car. Therefore, the convenience for students to intuitively observe the bottom structure of the car is not affected. On this basis, after the car is deflected, the connecting shaft is subjected to a torque in the direction of the car's deflection, and the torque will be transmitted to the scissors-type connection assembly through the upper auxiliary rod splined with the connecting shaft, that is, the force generated by the deflection of the car acts on the scissors-type connection assembly. As we all know, in automobile 4S stores, a scissors-type lifting platform structure is generally used, which is consistent with the principle of the scissors-type connection assembly in this solution, that is, it is feasible and reliable to use the scissors-type connection assembly to bear the car's deflection torque. Therefore, compared with the self-locking property of the worm gear that is easy to think of in the first method to bear the car's torque, the second method is safer.

[0041] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0042] Reference Figure 1-Figure 9 The multi-station training platform for new energy high-voltage system includes a whole vehicle display mechanism 400, a teaching platform 100 and a group measurement platform 200. Preferably, a fence 300 is arranged around the whole vehicle display mechanism 400. When the whole vehicle is displayed, the fence 300 is opened to allow students to approach the new energy vehicle on the whole vehicle display mechanism 400. In other cases, the fence 300 is closed to restrict students from approaching.

[0043] Embodiment 1

[0044] There is one teaching platform 100, and there are multiple group measurement platforms 200, four of which are shown in the attached figure of this scheme. In addition, both the teaching platform 100 and the group measurement platform 200 are provided with a general fault manual setting platform, equipped with resistors, signal generators and other devices that can set occasional faults, with connector pin numbers of each module, and measurement ports, and a resource query machine, etc. The teaching platform 100 is also provided with an instrument information display screen or indicator light, which is more convenient for teaching and showing the working status of the vehicle to students.

[0045] The general fault manual setting platform adopts an integrated design: the platform integrates resistors, signal generators, switches and other components, and can simulate various electrical faults, including open circuit, short circuit, poor contact, signal abnormality, etc.; the general fault manual setting platform adopts programmable control: introducing a programmable controller (PLC) or microprocessor to realize the automation and intelligence of fault setting, support preset fault sequences and random fault generation, and improve the flexibility and interest of teaching.

[0046] The resource query machine has built-in learning resources such as new energy vehicle maintenance manuals, circuit diagrams, fault diagnosis processes, etc. It supports online query and download, making it convenient for students to obtain the required information at any time.

[0047] The teaching platform 100 is also equipped with a high-definition projector and a touch screen for displaying teaching PPTs, video materials and real-time operation demonstrations, thereby enhancing the intuitiveness and interactivity of teaching.

[0048] The above-mentioned general fault manual setting platform is used to show students the status of new energy vehicles when they have different faults, so that students can understand the knowledge conveyed by the teacher. Furthermore, this is achievable with the existing technology. For example, the relevant content disclosed in the Chinese invention patent with authorization announcement number CN117711236B can be referred to, which will not be elaborated here.

[0049] Furthermore, the multiple group measurement platforms 200 are independent of each other. During learning, the students are divided into several groups corresponding to the multiple group measurement platforms 200. The group measurement platforms 200 have functions such as group learning, measurement, and information query. They do not interfere with each other during learning and measurement, and the group measurement platforms 200 are provided with indicator lights. Teachers can know the status of each group's homework through the lighting of the indicator lights or the feedback on the display screen.

[0050] Furthermore, a display panel is provided on the fence 300 to show the trainees the main components, working principles, circuit diagrams and common fault points of the vehicle, so as to facilitate the trainees' intuitive understanding and learning.

[0051] Furthermore, the universal fault manual setting platform adopts standardized male and female interface wiring harnesses, which are compatible with new energy vehicles of different models. The functions and corresponding modules of each line are clearly marked on the wiring harness, which is convenient for fault setting and troubleshooting. The wiring harness design can quickly replace the fault point according to different teaching needs, realizing the diversity and complexity of fault simulation.

[0052] Embodiment 2

[0053] Reference Figure 3-Figure 7 The whole vehicle display mechanism 400 includes a display platform 402, and a top seat 408 is respectively provided at both ends of the display platform 402. Initially, the upper surface of the top seat 408 is flush with the upper surface of the display platform 402. A ramp 401 is provided on one side of one of the top seats 408, and the new energy vehicle can move along the ramp 401 to the display platform 402.

[0054] A connecting shaft 409 is installed at the middle position of the opposite side of the two top seats 408 through a bearing, and the axial centerline direction of the connecting shaft 409 is parallel to the length direction of the display platform 402. The opposite ends of the two connecting shafts 409 are fixedly provided with fixing seats 410, and a frame is provided between the two fixing seats 410. The frame is rectangular and is located around the display platform 402. A plurality of fastening components 403 are provided on the frame. The fastening components 403 are used to form a fixed connection with the new energy vehicle on the display platform 402. The existing bolt fixing method, or the steel cable bundling method, etc. can be adopted. This is achievable in the existing technology and will not be elaborated. Furthermore, different models of new energy vehicles can be fixed by disassembling and assembling the fastening components 403, and multiple fixing methods such as bolts and steel cables can be adopted to make the fixation more stable.

[0055] The vehicle display mechanism 400 also includes a driving member 405 for driving the top seat 408 to move up and down in the vertical direction and driving the connecting shaft 409 to rotate. Two groups of driving members 405 are correspondingly arranged. In this solution, the driving member 405 is provided in two ways. It should be noted that these two ways are included but not limited to.

[0056] The first way of driving the member 405:

[0057] Reference Figure 5-Figure 7The driving component 405 includes a hydraulic motor 411 installed on the top seat 408. The hydraulic motor 411 and the connecting shaft 409 are connected to each other by a power connector 412. The power connector 412 adopts the existing worm gear technology. Furthermore, the power connector 412 includes a worm wheel installed on the connecting shaft 409 and a worm meshing with the worm wheel. Two worm gears are provided and are respectively located on both sides of the connecting shaft 409 along its own axial centerline direction; the connecting shaft 409 can be driven to rotate by the hydraulic motor 411, so that the new energy vehicle connected to the frame can be deflected. After the deflection, the power connector 412 has self-locking properties, which can keep the new energy vehicle in the current deflection state. However, due to the weight of the new energy vehicle of several tons, the torque brought to the power connector 412 is very large, which can easily cause the power connector 412 to be damaged over time, and the safety is relatively poor, but the deflection angle of the vehicle can be adjusted arbitrarily.

[0058] A base is disposed below the top seat 408 .

[0059] The driving member 405 also includes an upper slide seat 415 slidably mounted on the top seat 408 along the width direction of the display platform 402 and a lower slide seat 414 slidably mounted on the base along the width direction of the display platform 402. Two lower slide seats 414 are arranged along their own sliding direction, and two upper slide seats 415 are arranged along their own sliding direction.

[0060] A scissor-type connection assembly 416 is arranged between the two lower slide seats 414 and the two upper slide seats 415. When the two lower slide seats 414 move toward or away from each other, the top seat 408 can be driven to move up or down through the scissor-type connection assembly 416, and the two upper slide seats 415 move toward or away from each other. The scissor-type connection assembly 416 is a prior art, such as the lifting technology used in the car lifting platform in the car 4S shop, and will not be elaborated on.

[0061] The driving member 405 further includes a threaded shaft 413 mounted on the base. The axis of the threaded shaft 413 is parallel to the width direction of the display platform 402. The threaded shaft 413 is threadedly connected with the lower sliding seat 414. Two threaded shafts 413 are correspondingly provided.

[0062] The driving component 405 also includes a hydraulic motor 406 and a transmission shaft 407. A power connection is formed between the hydraulic motor 406 and the transmission shaft 407. A power connection is formed between the transmission shaft 407 and two threaded shafts 413. The threads of the two threaded shafts 413 have opposite rotation directions. Therefore, the hydraulic motor 406 can drive the two lower sliding seats 414 to move towards or away from each other.

[0063] The working principle of the first mode of the driving component 405 is: the two lower sliding seats 414 are driven to move towards or away from each other by the hydraulic motor 1 406, so that the top seat 408 can be driven to move up or down, so as to adjust the height of the new energy vehicle; the connecting shaft 409 is driven to rotate by the hydraulic motor 2 411, so that the frame can be driven to rotate around the axis of the connecting shaft 409, so that the new energy vehicle is deflected, and the bottom of the vehicle is exposed, which is more intuitive for students to watch.

[0064] The second way of driving the member 405:

[0065] Reference Figure 8 and Fig. 9 A base is provided below the top seat 408 .

[0066] The driving member 405 includes an upper slide seat 415 slidably mounted on the top seat 408 along the width direction of the display platform 402 and a lower slide seat 414 slidably mounted on the base along the width direction of the display platform 402. Two lower slide seats 414 are arranged along their own sliding direction, and two upper slide seats 415 are arranged along their own sliding direction.

[0067] The two lower slide seats 414 are driven to move toward or away from each other by the existing hydraulic technology. This is achievable by the existing technology, such as the lifting technology used by the car lifting platform in the car 4S shop, which will not be described in detail.

[0068] The driving member 405 further includes a scissor-type connection assembly 416 disposed between the two lower slide seats 414 and the two upper slide seats 415 . Further, the scissor-type connection assembly 416 includes a lower connecting rod 4161 and an upper connecting rod 4162 .

[0069] There are two lower connecting rods 4161, namely lower connecting rod 1 and lower connecting rod 2, wherein lower connecting rod 1 and lower connecting rod 2 are cross-hinged and the hinge position is named hinge point 1, hinge point 1 is located in the middle position of lower connecting rod 1 or lower connecting rod 2, and the bottoms of the two lower connecting rods 4161 are respectively hingedly connected with the two lower sliding seats 414.

[0070] There are two upper connecting rods 4162, namely upper connecting rod 1 and upper connecting rod 2, wherein upper connecting rod 1 and upper connecting rod 2 are cross-hinged and the hinge position is named hinge point 2, hinge point 2 is located in the middle position of upper connecting rod 1 or upper connecting rod 2, and the tops of the two upper connecting rods 4162 are respectively hingedly connected with the two upper slide seats 415.

[0071] The two upper connecting rods 4162 are respectively hingedly connected with the two lower connecting rods 4161 and the hinge position is named hinge point three. Hinge point three is located at the middle position between the bottom of the upper connecting rod 4162 and hinge point two, and hinge point three is located at the middle position between the top of the lower connecting rod 4161 and hinge point one.

[0072] The drive member 405 also includes a central seat 419 located directly below the connecting shaft 409 .

[0073] The driving member 405 further includes an upper auxiliary rod 417 and a lower auxiliary rod 418 .

[0074] The bottom of the lower auxiliary rod 418 is hingedly connected to the center seat 419, the top of the lower auxiliary rod 418 is hingedly connected to the bottom of the upper connecting rod 4162, the lower auxiliary rod 418 is also hingedly connected to the lower connecting rod 4161 and the hinge position is named hinge point four, hinge point four is located in the middle position of the lower auxiliary rod 418, hinge point four is located in the middle position between the bottom of the lower connecting rod 4161 and hinge point one, and two lower auxiliary rods 418 are correspondingly arranged.

[0075] The bottom of the upper auxiliary rod 417 is hingedly connected to the top of the lower connecting rod 4161, and the top of the upper auxiliary rod 417 is connected to the connecting shaft 409. The upper auxiliary rod 417 is also hingedly connected to the upper connecting rod 4162 and the hinge position is named hinge point five. Hinge point five is located in the middle position of the upper auxiliary rod 417. Hinge point five is located in the middle position between the top of the upper connecting rod 4162 and hinge point two. Two upper auxiliary rods 417 are correspondingly arranged, and one upper auxiliary rod 417 is movably connected to the connecting shaft 409, and the other upper auxiliary rod 417 is splinedly connected to the connecting shaft 409.

[0076] The working principle of the second mode of driving member 405 is as follows:

[0077] When the two lower slide seats 414 are driven to move toward each other by the existing hydraulic technology, the two upper slide seats 415 can be driven to move toward each other by the scissor-type connection assembly 416, thereby driving the top seat 408 to move upward. At the same time, the scissor-type connection assembly 416, the upper auxiliary rod 417 and the lower auxiliary rod 418 cooperate with each other to drive the connecting shaft 409 to rotate and rotate with the frame, thereby deflecting the car, that is, the car can be driven to move upward and deflect at the same time or move downward and reversely deflect and reset at the same time. The advantages of this method are:

[0078] Although the rotation angle of the connecting shaft 409 is limited by the scissor-type connecting assembly 416 and can only rotate between 0 and 90 degrees, it is enough to expose the bottom of the car. Therefore, the convenience for students to intuitively observe the bottom structure of the car is not affected. On this basis, after the car is deflected, the connecting shaft 409 is subjected to a torque in the direction of the car's deflection, and the torque will be transmitted to the scissor-type connecting assembly 416 through the upper auxiliary rod 417 splined with the connecting shaft 409, that is, the force generated by the deflection of the car acts on the scissor-type connecting assembly 416. As is known to all, in automobile 4S stores, a scissor-type lifting platform structure is generally adopted, which is consistent with the principle of the scissor-type connecting assembly 416 in this scheme, that is, it is feasible and reliable to bear the deflection torque of the car through the scissor-type connecting assembly 416. Therefore, compared with the self-locking property of the worm gear in the first method to bear the car torque, the second method is safer.

[0079] Preferred embodiment, refer to Figure 4 The upper surface array of the display platform 402 is provided with shooting holes, and the cameras 404 are installed in the shooting holes. When the teacher uses the teaching platform 100 to give a lecture, the camera 404 can be used to shoot the bottom of the car and transmit the picture to the display screen of the teaching platform 100.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
