Description

Technical Field

[0001] This utility model relates to the field of teaching demonstration technology, and in particular to a mobile motor teaching demonstration device. Background Technology

[0002] With societal progress, demonstration devices are frequently used in teaching to help students learn and understand. In teaching electric motors, motor demonstration models are used to simulate the operating principle of the motor and the direction of current.

[0003] Chinese Patent Publication No. CN116682313A discloses a mobile motor teaching demonstration device, including a frame. A display model is fixedly connected to the rear side of the inner cavity of the frame. An adjustment mechanism is provided at the bottom of the frame, and a moving mechanism is fixedly connected to the bottom of the adjustment mechanism. The adjustment mechanism includes an adjustment plate, and a control box is movably connected to the top of the front side of the adjustment plate. A first motor is fixedly connected to the bottom of the inner cavity of the control box. Screws are fixedly connected to both sides of the output end of the first motor. Threaded sleeves are fitted on the surface of the screws. The patent document describes how the screws can cooperate with the first motor to control the height of the threaded sleeves and connecting rods. The connecting rods can control the height of the frame, and a cylinder can control the position of the push wheel. The push wheel can press the adjustment plate and change the angle of the frame, solving the problems of existing motor teaching demonstration devices that are inconvenient to adjust the height and angle of use and have poor demonstration effects.

[0004] However, the mobile motor teaching demonstration device in the aforementioned patent literature still has significant shortcomings in use. Although the demonstration height can be adjusted by raising and lowering, it cannot be rotated or its angle adjusted, making it impossible to fully display all angles of the demonstration. Therefore, we propose a mobile motor teaching demonstration device to solve the above problems. Utility Model Content

[0010] Preferably, the adjustment assembly includes a second rotating disk, the lower end of which is rotatably connected to the bottom wall of the inner cavity of the outer shell. Two motors are fixedly connected to the upper end of the second rotating disk. The output ends of the two motors are fixedly connected to worm gears via couplings. Worm wheels are meshed on the outer surfaces of the two worm gears. The upper end of the worm wheel located at the lower part is fixedly connected to a second bevel gear via a shaft that passes through the lower end to the upper end of the fixed plate.

[0011] Preferably, the rocking assembly includes a rocking disc, the rear end of which is rotatably connected to the front end of the housing, and a bevel gear three is fixedly connected to the rear end of the rocking disc via a shaft.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model, through its demonstration and adjustment components, allows students to observe the motor's operation from the front, side, or top view via a rotating device, breaking through the limitations of traditional fixed viewing angles. Students in the back rows of the classroom can obtain a clear view through the rotating device, avoiding obstruction issues. Furthermore, in narrow outdoor or laboratory spaces, the angle adjustment optimizes the equipment's placement, improving space utilization. At the same time, teachers do not need to frequently move the equipment; they can switch the displayed content by rotating or tilting, saving class time. Additionally, dangerous components such as high-voltage circuits can be rotated to face away from students during demonstrations, reducing the risk of accidental contact. Moreover, the tilting device, combined with magnetic field line projection, allows observation of differences in magnetic field distribution at different angles.

[0017] 2. This utility model, through the setting of the rocking component and the lifting component, can realize the overall height adjustment device through the lifting adjustment device, further matching the demonstration content with the students' line of sight, ensuring that students in the back row of the classroom can also clearly observe the internal structure of the motor or the dynamic operation process. At the same time, teachers can adjust the height of the operating table according to their height, reducing fatigue during long-term demonstrations. When students practice, they can lower the device to a suitable height to avoid fatigue caused by bending over to operate. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, as Figure 1 As shown, a mobile motor teaching demonstration device includes a main body 1, a demonstration component 2 rotatably connected to the inner cavity of the main body 1, an adjustment component 3 rotatably connected to the inner cavity of the main body 1, a rocking component 4 rotatably connected to the front of the main body 1, and a lifting component 5 rotatably connected to the inner cavity of the main body 1.

[0026] When implementing this solution, the operator first pushes the device to the position where the demonstration is to be performed. Then, the operator first shakes the device to raise the height of the demonstration component 2. When it is necessary to rotate the device to different angles for demonstration, the operator first activates the upper adjustment component 3 to drive the demonstration component 2 to rotate, thus achieving the effect of rotational demonstration. When it is necessary to tilt the device for demonstration, the operator first activates the lower adjustment component 3 to drive the demonstration component 2 to tilt, thus achieving the effect of tilted demonstration.

[0027] Specifically, in order to demonstrate raising and lowering, such as Figure 2 and Figure 3 As shown, in this solution, the main body 1 includes a shell 11, and universal wheels 12 are fixedly connected to the four corners of the lower end of the shell 11. A handle 13 is fixedly connected to the upper rear end of the shell 11.

[0028] For further details, please refer to [link / reference]. Figure 2 and Figure 3 The rocking assembly 4 includes a rocking disk 41, the rear end of which is rotatably connected to the front end of the housing 11. A bevel gear 42 is fixedly connected to the rear end of the rocking disk 41 via a shaft. A bevel gear 43 is meshed with the outer surface of the bevel gear 42. Five pulleys 44 are rotatably connected to the bottom wall of the inner cavity of the housing 11. A belt 45 is wound around the outer surface of the five pulleys 44.

[0029] For further details, please refer to [link / reference]. Figure 4 The lifting assembly 5 includes reciprocating lead screws 51. The lower ends of the four reciprocating lead screws 51 are rotatably connected to the bottom wall of the inner cavity of the outer casing 11. The outer surfaces of the four reciprocating lead screws 51 are slidably connected to sliding shells 52. The upper ends of the four sliding shells 52 are fixedly connected to springs 53.

[0030] For further details, please refer to [link / reference]. Figure 2 and Figure 3 The lower end of the bevel gear 43 is fixedly connected to the upper end of the pulley 44 located in the middle via a shaft, and the outer surfaces of the four reciprocating screws 51 are fixedly connected to the inner surfaces of the four pulleys 44 located at the four corners.

[0031] When implementing this solution, the operator first pushes handle 13 to move the device to the position where it needs to be demonstrated. Then, the operator first shakes the rocker plate 41 to drive the bevel gear 3 42, bevel gear 43, pulley 1 44 and belt 1 45 to rotate, which in turn causes the reciprocating screw 51 to rotate. This causes the sliding shell 52 to slide while the spring 53 and sliding rod 23 slide, thereby raising the top height of the shell 11 for demonstration purposes.

[0032] Example 2 is a demonstration of rotation and angle adjustment based on Example 1.

[0033] Specifically, for the demonstration of rotation and angle adjustment, such as Figure 4 As shown, in this scheme, the demonstration component 2 includes a rotating disk 22, the outer surface of the rotating disk 22 is rotatably connected to the inner surface of the outer shell 11, the upper end of the rotating disk 22 is fixedly connected to the demonstration model 21, the lower middle part of the rotating disk 22 is fixedly connected to the sliding rod 23, the outer surface of the sliding rod 23 is slidably connected to the mating shell 24, the lower end of the mating shell 24 is fixedly connected to the wedge block 25, the inner surface of the wedge block 25 is fixedly connected to the fixing plate 26, and the rear side wall of the inner cavity of the fixing plate 26 is rotatably connected to the bevel gear 27.

[0034] For further details, please refer to [link / reference]. Figure 3 , Figure 4 and Figure 5 The adjustment component 3 includes a rotating disk 31. The lower end of the rotating disk 31 is rotatably connected to the bottom wall of the inner cavity of the outer shell 11. Two motors 32 are fixedly connected to the upper end of the rotating disk 31. The output ends of the two motors 32 are fixedly connected to worm gears 33 through couplings. Worm gears 34 are meshed on the outer surfaces of the two worm gears 33. The upper end of the worm gear 34 located at the lower part passes through the lower end of the fixed plate 26 to the upper end through a shaft and is fixedly connected to a bevel gear 35.

[0035] For further details, please refer to [link / reference]. Figure 3 and Figure 4 The lower end of the fixed plate 26 is fixedly connected to the upper end of the worm gear 34 located at the top via a shaft. The lower end of the second bevel gear 35 is rotatably connected to the bottom wall of the inner cavity of the fixed plate 26. The outer surface of the second bevel gear 35 meshes with the outer surface of the first bevel gear 27.

[0036] When this solution is implemented, if it is necessary to rotate to different angle positions for demonstration, the operator first starts the upper motor 32 to drive the worm gear 33, the fixed plate 26, the mating shell 24, the sliding rod 23 and the rotating disk 22 to rotate, thus achieving the effect of rotating the demonstration model 21.

[0037] At the same time, rotating disk 31 will also rotate, so that it can always rotate and tilt at a specific angle when tilting;

[0038] When a tilting demonstration is required, the operator first starts the upper motor 32 to drive the worm 33, worm wheel 34, bevel gear 2 35, bevel gear 1 27, wedge block 25, mating shell 24, sliding rod 23, and the top of the outer shell 11 to rotate and tilt, thereby achieving the effect of tilting the demonstration model 21.

[0039] When tilting is required, the top of the housing 11 must be raised before it can be tilted. At the same time, the sliding rod 23 is in the middle of the top of the housing 11, which can prevent the top of the housing 11 from shaking. When tilting is required, the spring 53 can also tilt the top of the housing 11.

[0040] The sliding housing 52 has a latch inside, which can slide within the groove of the reciprocating lead screw 51.

[0041] In summary, the implementation process of this utility model is as follows:

[0042] The operator first pushes handle 13 to move the device to the position where it needs to be demonstrated. Then, the operator first shakes the rocker plate 41 to drive the bevel gear 3 42, bevel gear 43, pulley 1 44 and belt 1 45 to rotate, which in turn causes the reciprocating screw 51 to rotate. When the sliding shell 52 slides, the spring 53 and the sliding rod 23 slide up, thereby raising the top height of the shell 11 for demonstration purposes.

[0043] When it is necessary to rotate to different angle positions for demonstration, the operator first starts the upper motor 32 to drive the worm gear 33, the fixed plate 26, the mating shell 24, the sliding rod 23 and the rotating disk 22 to rotate, thus achieving the effect of rotating the demonstration model 21;

[0044] When a tilting demonstration is required, the operator first starts the upper motor 32 to drive the worm gear 33, worm wheel 34, bevel gear 25, bevel gear 1 27, wedge block 25, mating shell 24, sliding rod 23, and the top of the outer shell 11 to rotate and tilt, thereby achieving the effect of tilting the demonstration model 21.

[0045] It should be noted that the specific installation method, circuit connection method, and control method of the motor 32 and other components used in this utility model are all conventional designs, and will not be described in detail here.
