Description

Technical Field

[0001] This utility model relates to the field of teaching aids technology, and in particular to a generator principle demonstration model teaching aid. Background Technology

[0002] Teaching aids are essential physical tools for disseminating scientific and technological knowledge and conducting educational activities, playing an indispensable role in the learning and growth of teenagers. In physics learning, generators, as common power generation devices, are one of the knowledge points that students must master. To help students better understand the principles of power generation, hand-cranked generators are often used in on-site teaching.

[0003] However, most hand-cranked generator teaching aids on the market currently adopt a closed design, which prevents students from freely adjusting parameters such as magnet spacing. This limits students' in-depth understanding and exploration of generator principles. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a generator principle demonstration model teaching aid to solve the problems mentioned above in the background technology.

[0005] A generator principle demonstration model teaching aid includes a power supply component, including a base, a coil mounting component detachably mounted on the base via a rotating component, and two magnetic poles respectively mounted on the base and symmetrically distributed on both sides of the coil mounting component via a moving component;

[0006] The moving component includes a groove on the base, a slider slidably disposed in the groove, and a limiting member connected to the slider via an elastic element. The magnetic pole is fixed to the top of the slider. The elastic force of the elastic element forces the limiting member to press against the side wall of the groove, so that the slider can be locked at any position in the groove, and the distance between the magnetic pole and the coil mounting component can be adjusted by sliding.

[0007] Compared to existing technologies, the advantages of this application are as follows: By pressing the limiting member, the elastic member is compressed, causing the limiting member to no longer press against the side wall of the slide groove, thus allowing the slider to move freely. The operator can move the slider along the slide groove to adjust the distance between the magnetic pole and the coil mounting component. When the slider reaches the appropriate position, the operator releases the limiting member, the elastic member regains its elasticity, and the limiting member presses against the side wall of the slide groove again, thereby locking the slider in the current position. This design, through the cooperation of the limiting member, the slider, and the slide groove, achieves flexible adjustment of the distance between the magnetic pole and the coil, helping students better understand and explore the principles of generators.

[0008] Furthermore, the limiting member is a U-shaped structure, with its two ends extending outward to form a pressure block and a limiting block, respectively, and the distance between the pressure block and the limiting block is adapted to the thickness of the sidewall of the slide groove.

[0009] Furthermore, the slide groove includes a limiting groove and a connecting groove that are interconnected, the size of the limiting groove being larger than the connecting groove, and the slider includes a limiting part and a connecting part extending to the top of the limiting part, the size of the limiting part being larger than the connecting part.

[0010] Furthermore, the rotating assembly includes a rotating rod disposed on the base, a transmission structure extending through the top plate of the base and connected to the rotating rod, and two limiting plates disposed on the rotating rod. The coil mounting component has a central insertion hole that matches the rotating rod, and the coil mounting component is sleeved on the rotating rod through the insertion hole. The limiting plates are used to limit the axial displacement of the coil mounting component.

[0011] Furthermore, the transmission structure includes a first transmission bevel gear mounted at the bottom of the rotating rod, a second transmission bevel gear engaged with the first transmission bevel gear, and a drive handle connected to the second transmission bevel gear, the drive handle extending outward through the side wall of the base.

[0012] Furthermore, the sidewall of the slide is provided with scale lines to indicate the magnetic pole spacing corresponding to the sliding distance of the slider.

[0013] Furthermore, the coil mounting component is composed of multiple stacked mounting parts; each mounting part includes a central plate, a plurality of support rods evenly distributed along the outer circumference of the central plate, and an arc-shaped limiting plate disposed at the end of the support rod; wherein, adjacent support rods and the arc-shaped limiting plate enclose a limiting space for fixing the coil.

[0014] Furthermore, the slider sidewall is provided with a receiving groove, one end of the elastic element is fixed to the inner wall of the receiving groove, and the other end is connected to the limiting element, the size of the limiting element being adapted to the receiving groove.

Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Please see Figures 1 to 3 The image shows a generator principle demonstration model teaching aid in an embodiment of the present utility model, including a base 10, a coil mounting component 50 detachably mounted on the base 10 via a rotating component 20, and two magnetic poles 40 respectively mounted on the base 10 and symmetrically distributed on both sides of the coil mounting component 50 via a moving component 30.

[0026] The moving component 30 includes a groove 31 disposed on the base 10, a slider 32 slidably disposed in the groove 31, and a limiting member 34 connected to the slider 32 by an elastic member 33. The magnetic pole 40 is fixed to the top of the slider 32. The elastic force of the elastic member 33 forces the limiting member 34 to press against the side wall of the groove 31, so that the slider 32 can be locked at any position in the groove 31, and the distance between the magnetic pole 40 and the coil mounting member 50 can be adjusted by sliding.

[0027] It is worth noting that by pressing the limiting member 34, the elastic member 33 is compressed, causing the limiting member 34 to no longer press against the side wall of the slide groove 31, thus allowing the slider 32 to move freely. The operator can move the slider 32 along the slide groove 31 to adjust the distance between the magnetic pole 40 and the coil mounting member 50. When the slider 32 moves to the appropriate position, the operator releases the limiting member 34, the elastic member 33 regains its elasticity, causing the limiting member 34 to press against the side wall of the slide groove 31 again, thereby locking the slider 32 in the current position. This design, through the cooperation of the limiting member 34, the slider 32, and the slide groove 31, achieves flexible adjustment of the distance between the magnetic pole 40 and the coil, helping students better understand and explore the generator principle.

[0028] Please see Figures 4 to 5 Furthermore, the limiting member 34 has a U-shaped structure, with its two ends extending outward to form a pressure block 35 and a limiting block 36, respectively. The distance between the pressure block 35 and the limiting block 36 is adapted to the thickness of the sidewall of the slide groove 31.

[0029] Furthermore, the slide 31 includes a limiting groove 311 and a connecting groove 312 that are interconnected. The size of the limiting groove 311 is larger than that of the connecting groove 312. The slider 32 includes a limiting part 321 and a connecting part 322 extending to the top of the limiting part 321. The size of the limiting part 321 is larger than that of the connecting part 322.

[0030] In this embodiment, when the limiting member 34 needs to release its pressure on the side wall of the slide groove 31, the operator presses the pressure block 35, causing the limiting member 34 to compress the elastic member 33. The elastic member 33 can be a spring.

[0031] Furthermore, the rotating assembly 20 includes a rotating rod 21 disposed on the base 10, a transmission structure 22 extending through the top plate of the base 10, and two limiting plates 23 disposed on the rotating rod 21. The coil mounting component 50 has a central insertion hole matching the rotating rod 21, and the coil mounting component 50 is sleeved on the rotating rod 21 through the insertion hole. The limiting plates 23 are used to limit the axial displacement of the coil mounting component 50. In this embodiment, the limiting plates 23 are threadedly connected to the rotating rod 21.

[0032] Specifically, the transmission structure 22 includes a first transmission bevel gear 221 installed at the bottom of the rotating rod 21, a second transmission bevel gear 222 cooperating with the first transmission bevel gear 221, and a drive handle 223 connected to the second transmission bevel gear 222. The drive handle 223 extends outward through the side wall of the base 10.

[0033] In practice, when it is necessary to replace the coil mounting piece 50 with a different number of coils, the operator can unscrew the limiting plate 23 at the top of the rotating rod 21, remove the original coil mounting piece 50, and install the mounting piece with a different number of coils onto the rotating rod 21. Finally, the limiting plate 23 is tightened to fix it. This process allows for flexible adjustment of the number of coils. When the drive handle 223 is rotated, it will drive the second transmission bevel gear 222 to rotate, which in turn drives the first transmission bevel gear 221 to rotate, thereby causing the rotating rod 21 and the coil mounting piece 50 to rotate together.

[0034] Furthermore, the sidewall of the slide groove 31 is provided with scale lines to indicate the spacing of the magnetic poles 40 corresponding to the moving distance of the slider 32.

[0035] Please see Figure 6 In this embodiment, the coil mounting component 50 is composed of a plurality of stacked mounting portions 51; the mounting portion 51 includes a central plate 52, a plurality of support rods 53 evenly distributed along the outer circumference of the central plate 52, and an arc-shaped limiting plate 5423 disposed at the end of the support rods 53; wherein, the adjacent support rods 53 and the arc-shaped limiting plate 5423 form a limiting space 55 for fixing the coil (not shown).

[0036] In this embodiment, the slider 32 has a receiving groove 37 on its side wall, one end of the elastic member 33 is fixed to the inner wall of the receiving groove 37, and the other end is connected to the limiting member 34. The size of the limiting member 34 is adapted to the receiving groove 37.

[0037] In summary, the generator principle demonstration model teaching aid in the above embodiments of this utility model has the following characteristics:

[0038] Beneficial effects:

[0039] By pressing the limiting member 34, the elastic member 33 is compressed, causing the limiting member 34 to no longer press against the side wall of the slide groove 31, thus allowing the slider 32 to move freely. The operator can move the slider 32 along the slide groove 31 to adjust the distance between the magnetic pole 40 and the coil mounting member 50. When the slider 32 moves to the appropriate position, the operator releases the limiting member 34, the elastic member 33 regains its elasticity, causing the limiting member 34 to press against the side wall of the slide groove 31 again, thereby locking the slider 32 in the current position. This design, through the cooperation of the limiting member 34, the slider 32, and the slide groove 31, achieves flexible adjustment of the distance between the magnetic pole 40 and the coil, helping students better understand and explore the generator principle.
