Description

Technical Field

[0001] The utility model relates to the technical field of automobile engines, in particular to a teaching device for automobile engine maintenance. Background Art

[0002] A car engine is an internal combustion engine that generates power to drive the car. It ignites and burns a mixture of fuel and air, converting chemical energy into mechanical energy to drive the car forward. Car engines are usually divided into two types: internal combustion engines and external combustion engines. Currently, most cars use internal combustion engines, which can be divided into gasoline engines and diesel engines according to the fuel. A gasoline engine uses gasoline as fuel, which is ignited by an ignition plug to cause the fuel mixture in the cylinder to explode, pushing the piston to reciprocate and generate power. A diesel engine uses diesel as fuel, sprays diesel into the cylinder through high-pressure injection, and then compresses the diesel to self-ignite, generating an explosion that pushes the piston to work, thereby driving the car. A car engine is usually composed of a cylinder, a piston, a crankshaft, a valve, an ignition system, a fuel system, a cooling system, etc. The performance of the engine directly affects the power output, fuel efficiency and emission level of the car. Therefore, the design and technical level of the engine are crucial to the overall performance of the car. When teaching the use of car engines, a teaching device for car engine maintenance is one of the indispensable equipment.

A plurality of slots 8 are equidistantly provided on the front side of the outer wall of the display board 9. A plug rod 20 is engaged with the inner side of the slot 8. The front end of the plug rod 20 is rotatably connected to a rotating shaft 19. A plastic buckle 12 is installed on the front side of the rotating shaft 19. A line rope 11 is provided on the inner side of the plastic buckle 12. Both ends of the line rope 11 are provided with neodymium magnet blocks 10. An adjustment mechanism 2 is installed on the bottom of the mounting plate 1. A slide bar 13 is fixedly connected to the outer wall of the insert block 14. A slide groove 7 is provided on the inner side of the slot 22. The slide bar 13 is slidably connected to the slide groove 7. A magnet sheet 18 is installed on the rear side of the insert block 14 and the inner rear side of the slot 22.

[0031] Specifically, the component model is installed on the plug block 14; this process is very simple, just insert the plug block 14 into the slot 22; at the same time, the slide bar 13 slides in the slide slot 7 to play a limiting role, ensuring that the plug block 14 does not exceed the predetermined range during movement; when the plug block 14 collides with the rotating plate 16, the torsion spring 15 is forced to drive the rotating plate 16 to deform and store energy and flip; this design enables the rotating plate 16 to fit the plug block 14 horizontally, and at the same time the two magnet sheets 18 are adsorbed to fix the model in place; after the fixation is completed, it is necessary to take the insertion rod 20 and insert it into the card slot 8 for engagement; multiple insertion rods 20 can be installed to facilitate the adjustment of angles as needed; at this time, the plastic buckle 12 can be rotated, and at the same time the neodymium magnet block 10 is strongly magnetically adsorbed to connect multiple line ropes 11; such a design can not only simulate the route diagram of the line, but also can easily and quickly pull out the plug block 14 and the insertion rod 20 separately when the line rope 11 and the model need to be disassembled.

[0032] Reference Figure 1 and Figure 3The adjustment mechanism 2 includes a connecting rod 205, the top of which is fixedly connected to the bottom wall of the mounting plate 1, a fixing ring 203 is arranged on the outer side of the connecting rod 205, a worm 201 is rotatably connected to the right side of the fixing ring 203, a placing plate 5 is fixedly connected to the bottom of the fixing ring 203, a rotating rod 202 is rotatably connected to the top left side of the placing plate 5, a worm wheel 204 is fixedly connected to the top of the rotating rod 202, the worm wheel 204 is meshedly connected to the worm 201, and the worm wheel 204 is fixedly connected to the mounting plate 1 through the connecting rod 205; arc grooves 21 are provided on the left and right sides of the bottom of the mounting plate 1, and the arc grooves 21 are slidably connected to the fixing ring 203; a self-locking knob 23 is installed at the front end of the worm 201;

[0033] Specifically, the rotation self-locking knob 23 is tightly combined with the worm 201 so that they can rotate together; this rotation is transmitted to the connecting rod 205 through the meshing transmission of the worm 201 and the worm wheel 204, thereby realizing the synchronous rotation of the worm wheel 204 and the connecting rod 205. This process eventually allows the mounting plate 1 to rotate; the rotating mounting plate 1 allows the trainees in the factory to clearly see the display board 9 no matter where they are; this is the core purpose of the rotating self-locking knob 23 to drive the entire system; during the rotation of the mounting plate 1, the fixing ring 203 slides in the arc groove 21; this design is very clever, it can not only fix the position of the mounting plate 1, but also plan the rotation trajectory of the mounting plate 1; in this way, no matter where the trainees are, they can see the content on the display board 9, which greatly improves the convenience of viewing; in general, this design realizes the all-round viewing of the display board 9 by the trainees in the factory through the coordinated action of the rotating self-locking knob 23, the worm 201, the worm wheel 204, the connecting rod 205 and the mounting plate 1; at the same time, the sliding of the fixing ring 203 in the arc groove 21 not only ensures the stability of the mounting plate 1, but also provides a clear path for its rotation.

[0034] Reference Figure 1 Universal wheels 6 are installed at the four corners of the bottom of the placement board 5, and handles 3 are installed at the front and rear ends of the left side of the placement board 5; multiple placement boards 5 are fixedly connected by support columns 4;

When the plug block 14 collides with the rotating plate 16, the torsion spring 15 is forced to drive the rotating plate 16 to deform and store energy to flip, so that the rotating plate 16 flips to horizontally fit the plug block 14, and at the same time, the two magnet pieces 18 are adsorbed to fix the model. After the fixation is completed, take the plug rod 20 and insert it into the card slot 8 for engagement. Multiple plug rods 20 can be installed. Rotate the plastic buckle 12 according to the required angle, and at the same time, the neodymium magnet block 10 is strongly adsorbed to make multiple line ropes 1 1 can be connected to simulate the line trend diagram. When the line rope 11 and the model need to be disassembled, the plug block 14 and the plug rod 20 can be pulled out respectively, which can meet the use requirements, and the self-locking knob 23 is rotated to rotate the worm 201, and the rotation of the worm 201 is meshed with the worm wheel 204 to drive the worm wheel 204 and the connecting rod 205 to rotate, thereby rotating the mounting plate 1. Through the rotation of the mounting plate 1, the trainees at different angles in the factory can view the display board 9.
