Technical Field

[0001] This utility model relates to the field of teaching platform technology, and more specifically to a teaching platform for automobile engines. Background Technology

[0002] In the fields of education and training for modern automotive engineering, mechanical engineering, and related majors, the teaching of engines as core components is crucial. With the rapid development of automotive technology, traditional single-function engine teaching tools are no longer sufficient to meet the growing teaching demands. On the one hand, modern engines have increasingly complex structures, integrating numerous advanced electronic control systems. Traditional teaching benches often only demonstrate the basic mechanical structure and simple operating principles of engines, lacking the ability to provide intuitive and in-depth demonstrations of these complex electronic control and collaborative systems. On the other hand, teaching scenarios are also becoming more diverse. Not only is it necessary to provide clear demonstrations of engine principles during classroom theoretical explanations, but practical operation training also requires benches to more conveniently and efficiently complete the simulation demonstrations of engine mounting and complex circuit systems, allowing students to truly understand the engine's performance and changes in operating status during operation.

[0003] Existing automotive engine teaching benches are generally simple supports that place automotive engines on the supports for students to learn from. For example, there is a new energy vehicle engine disassembly and assembly teaching bench with the existing technology publication number CN208954481U.

[0004] However, the existing technology has the following problems when used: the teaching bench has a simple structure, and the car engine is placed directly on the bench. Students can only learn by simple disassembly. They need to use the engine fixing device and special circuit testing equipment to understand the structure and circuit system of the car engine, which will affect the teaching quality and efficiency. Therefore, this utility model provides a multi-functional car engine teaching bench. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides an automobile engine teaching bench to solve the problem that the traditional automobile engine teaching bench has simple functions, which affects the teaching quality and efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a teaching bench for automobile engines, including a support frame, an engine mounting bracket for placing automobile engines is provided inside the support frame, the engine mounting bracket is connected to the support frame by a connecting component, the connecting component includes two connecting plates, both of which are connected to the support frame and the engine mounting bracket by pins, and a detection component for detecting automobile engines is provided at the top of the support frame.

[0007] In a preferred embodiment, the connecting assembly further includes a positioning block and two positioning rods fixed to the inner wall of the rear end of the support frame. The two positioning rods are located on both sides of the positioning block. Positioning holes adapted to the positioning rods are opened on both sides of the rear end of the engine mounting bracket. The rear end of the engine mounting bracket contacts the front end of the positioning block. A limiting block is fixed to the inner wall of one side of the support frame. The limiting block contacts one side of the engine mounting bracket.

[0008] In a preferred embodiment, the front end and both sides of the support frame are detachably connected to protective covers.

[0009] In a preferred embodiment, the support frame includes four columns, two short crossbeams, two long crossbeams, two short crossbeams, and two long crossbeams. The short crossbeams, long crossbeams, short crossbeams, and long crossbeams are all detachably fixed to the columns via short connecting blocks.

[0010] In a preferred embodiment, the engine mounting bracket includes four support legs, two short support beams, two long support beams, two short fixed beams, and two long fixed beams. Each support leg is fixed with a traveling wheel at its bottom end. The short support beams, long support beams, short fixed beams, and long fixed beams are detachably connected to the support legs via long connecting blocks.

[0011] In a preferred embodiment, the detection component includes a display teaching panel, and a pressure gauge, a panel circuit diagram, a diagnostic socket, and a tachometer are fixedly disposed at the front end of the display teaching panel.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model combines the engine fixing function and the circuit system detection function into one, eliminating the need for frequent switching between different devices, greatly improving teaching quality and efficiency, while also enriching the practical training content for students. Students can intuitively compare the circuit diagram and the actual engine to understand and analyze the working principle of the control system.

[0015] 2. Setting up positioning blocks, positioning rods, and limit blocks to assist students in installing the engine mounting bracket can not only effectively prevent the engine mounting bracket from shifting position, but also greatly improve its installation efficiency, thereby greatly improving the overall teaching efficiency.

[0016] 3. The teaching platform effectively saves space, making the laboratory layout more compact and reasonable, and greatly reducing the teaching space. The compact platform design also makes it convenient for teachers to provide concentrated guidance to students during the teaching process.

[0017] 4. The teaching platform simulates a real working environment, providing students with a more realistic experience in practical operation. They can learn how to safely and accurately perform circuit testing even with the engine already installed, avoiding operational errors that might occur in actual work due to only being familiar with engine mounting or circuit testing alone. Furthermore, the circuit diagram includes relevant fault detection interfaces, and corresponding fault setting switches are located on the back of the diagram. By manually setting circuit faults, students can complete circuit testing during practical operation. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Refer to the instruction manual appendix Figure 1-5 This utility model provides a teaching bench for automobile engines, including a support frame 1. The support frame 1 has an engine mounting bracket 2 for placing automobile engines inside. The engine mounting bracket 2 is connected to the support frame 1 through a connecting component 3. Specifically, the connecting component 3 includes two connecting plates 31, both of which are connected to the support frame 1 and the engine mounting bracket 2 through pins 32. The top of the support frame 1 is provided with a detection component 4 for detecting automobile engines.

[0032] And, as Figure 2-3 As shown, the connecting component 3 also includes a positioning block 33 and two positioning rods 34 fixed to the inner wall of the rear end of the support frame 1. The two positioning rods 34 are located on both sides of the positioning block 33. Positioning holes 35 adapted to the positioning rods 34 are provided on both sides of the rear end of the engine mounting bracket 2. The rear end of the engine mounting bracket 2 contacts the front end of the positioning block 33. A limiting block 36 is fixed to one side of the inner wall of the support frame 1. The limiting block 36 contacts one side of the engine mounting bracket 2.

[0033] For safety, protective covers 5 are detachably connected to the front end and both sides of the support frame 1. The protective covers 5 are made of stainless steel and are of moderate height. They can prevent students from accidentally contacting the moving parts of the engine during operation without affecting the observation of the engine and the teaching demonstration.

[0034] Specifically, such as Figure 3 As shown, the support frame 1 includes four columns 11, two short crossbeams 12, two long crossbeams 13, two short crossbeams 14, and two long crossbeams 15. The short crossbeams 12, 13, 14, and 15 are detachably fixed to the columns 11 via short connecting blocks 16. Bolts are provided on the short connecting blocks 16, which are used to fix the short connecting blocks 16 to the columns 11, making the assembly of the entire support frame 1 very simple.

[0035] Specifically, such as Figure 4 As shown, the engine mounting bracket 2 includes four support legs 21, two short support beams 22, two long support beams 23, two short fixed beams 24, and two long fixed beams 25. Each support leg 21 has a fixed wheel 26 at its bottom. The short support beams 22, long support beams 23, short fixed beams 24, and long fixed beams 25 are detachably connected to the support legs 21 via long connecting blocks 27. Like the short connecting blocks 16, the long connecting blocks 27 are also connected to the support legs 21 via bolts, thus facilitating the assembly of the entire engine mounting bracket 2. Figure 6 As shown.

[0036] When conducting engine disassembly and assembly training, the engine can be directly hoisted onto the engine mounting bracket 2 and fixed to the long support beam 23. For engine electronic control training, the specific procedure is as follows: move the engine mounting bracket 2, carrying the engine, to the front of the support frame 1. Then remove the protective cover 5, long beam one 13, and long beam two 15. Next, push the engine along with the engine mounting bracket 2 into the support frame 1. At this point, it is important to ensure that the right side wall of the engine mounting bracket 2 contacts the limiting block 36, and that the two positioning holes 35 at the rear end of the engine mounting bracket 2 are aligned. Do not insert it into the two positioning rods 34. Use the positioning rods 34 and the limiting block 36 to limit the engine mounting bracket 2. At the same time, the positioning block 33 limits the engine mounting bracket 2 at the rear end. You can directly push the engine mounting bracket 2, which greatly improves the placement efficiency of the engine and ensures that the engine mounting bracket 2 is placed in an accurate position. Then, use the connecting plate 31 and the pin 32 to fix the engine mounting bracket 2 to the support frame 1 together. Connect the engine electrical interface to the circuit of the detection component 4. Finally, reinstall the protective cover 5 to complete the installation of the engine on the multi-functional automotive engine teaching bench.

[0037] To improve the practicality of teaching, such as Figure 1-3 As shown, the detection component 4 includes a display teaching panel 41, and a pressure gauge 42, a panel circuit diagram 43, a diagnostic socket 44 and a tachometer 45 are fixedly provided at the front end of the display teaching panel 41.

[0038] The test display teaching panel 41 displays a detailed engine circuit diagram. Lead wires are located on the back of the panel circuit diagram 43, connecting the panel circuit diagram 43 to the engine circuit via a diagnostic socket 44. The wiring between the various engine circuit components and the test display teaching panel 41 uses high-temperature resistant and wear-resistant wires. During connection, strict adherence to automotive circuit wiring standards is maintained to avoid wire crossings and tangles. Both ends of the wires use standard automotive connectors to ensure reliable and easy connection. Rubber protective rings are used to protect the wire insulation from scratches during the wiring process between the engine and the teaching panel. Parallel leads are provided at locations where frequent plugging and unplugging is required, allowing students to complete circuit testing without frequent plugging and unplugging, preventing cable damage from frequent plugging and unplugging. Students can test the circuit diagram on the display teaching panel 41 during practical operation and perform engine circuit tests without needing to unplug the engine connector. A fault switch is located on the back of the panel circuit diagram 43, allowing for the setting of circuit faults, enriching the student training content.

[0039] To facilitate adjustment of the angle of the display teaching panel 41, such as Figure 6 As shown, a fixing plate 6 is fixedly provided at the bottom of the display teaching panel 41. A rotating rod 7 passes through the inside of the fixing plate 6. Both ends of the rotating rod 7 are fixed to the top of the long crossbeam 13 through support plates 8. A servo motor 9 for driving the rotating rod 7 to rotate is fixed on one of the support plates 8. When the servo motor 9 drives the rotating rod 7 to rotate, the rotating rod 7 drives the display teaching panel 41 to rotate through the fixing plate 6, which can automatically adjust the angle of the display teaching panel 41. After it is not in use, the display teaching panel 41 can be flipped to the top of the support frame 1, thereby reducing the space occupied by the display teaching panel 41 and protecting the pressure gauge 42, panel circuit diagram 43, diagnostic socket 44 and tachometer 45 on the display teaching panel 41.
