[0001] This application relates to the technical field of teaching aids, and particularly to an adder. Background Art

[0002] In the field of teaching, there is a lack of a physical model that can be assembled, disassembled, and whose entire operation process can be clearly seen, which can guide students to analyze and think actively in practice. Especially in Internet information technology, as an arithmetic logic unit, the adder has an irreplaceable position in information technology. When students initially come into contact with programming in different number systems, due to its abstraction, it is not convenient for teaching and students' understanding. Summary of the Invention

[0003] The purpose of this application is to provide an adder that can more intuitively observe the addition working principle in different number systems, facilitating teaching.

[0004] To this end, an embodiment of this application provides an adder, which includes:

[0005] It includes a first module and a second module arranged in sequence along a first direction, and adjacent modules are connected by adjusting members.

[0006] The adjusting member includes a dial and a plurality of adjusting pieces evenly distributed circumferentially. There is a preset angle between any adjacent adjusting pieces. The first module includes a first gear, and the second module includes a second gear. The rotation of the adjusting piece can drive the second gear to rotate. The rotation of the first gear can drive the dial to rotate, so that when the dial rotates one week with the first gear, the dial can push the plurality of adjusting pieces to rotate the preset angle, thereby driving the second gear to rotate a preset number of teeth.

[0007] When the adder is an N - base number system, the ratio of the preset number of teeth to the total number of teeth of the second gear is 1 / N.

[0008] In a possible implementation, the first module includes a first mounting bracket, and the first gear is rotatably connected to the first mounting bracket through a rotating shaft.

[0009] The first module further includes a plurality of first transmission gears and an output gear that mesh with each other along the first direction. The first transmission gears are meshed between the first gear and the output gear. The first transmission gears and the output gear are respectively connected to the first mounting bracket through the rotating shaft. The number of teeth of the first gear and the output gear is the same, and the rotation directions of the first gear and the output gear are opposite.

[0010] The dial is connected to the rotating shaft corresponding to the output gear.

[0011] In a possible implementation, the second module includes a second mounting frame, and the second gear is rotatably connected to the second mounting frame via the rotating shaft.

[0012] The second module also includes an input gear and a plurality of second transmission gears meshing along the first direction, the second transmission gear meshing between the second gear and the input gear, the input gear and the output gear are arranged adjacent to each other, the input gear and the second transmission gear are respectively connected to the second mounting frame through the rotating shaft, and the input gear and the second gear have different numbers of teeth.

[0013] The plurality of adjustment plates are circumferentially arranged on the rotating shaft corresponding to the input gear.

[0014] In a possible implementation, the number of teeth on the first gear is the same as the number of teeth on the second gear, and the number of teeth on the second gear is different from the number of teeth on the input gear. When the first gear rotates one circle and drives the paddle to rotate one circle, the input gear rotates by the preset angle driven by the adjusting plate, and the number of teeth rotated corresponding to the preset angle of the input gear is the preset number of teeth, thereby driving the second gear to rotate by the preset number of teeth driven by the meshed second transmission gear.

[0015] In one possible implementation, the adder is binary, driving the first gear to rotate two times, the first transmission gear drives the output gear to rotate two times in the opposite direction, the paddle rotates two times accordingly, and causes the matching adjustment plate to rotate twice the preset angle, thereby driving the second gear to rotate one circle.

[0016] In a possible implementation, the number of the plurality of adjustment plates is 6, and along the circumference of the rotating shaft, the preset angle between any adjacent adjustment plates is 60°.

[0017] In a possible implementation, the paddle is provided with a protrusion, and when the rotating shaft drives the paddle to rotate, the protrusion can extend between adjacent adjustment plates, and as the rotating shaft rotates, the protrusion can abut against the adjustment plate to push the adjustment plate to rotate the preset angle.

[0018] In a possible implementation, there are multiple second modules, and the multiple second modules are arranged on one side of the first module along the first direction. Adjacent second modules are connected by the adjusting member, and the paddle is provided on the rotating shaft corresponding to the second gear, and the multiple adjusting plates are provided on the rotating shaft corresponding to the input gear.

[0019] In a possible implementation, the first module further includes a first transmission group, a second transmission group, and a speed changer. The speed changer can select one of the multiple first transmission gears, the first transmission group, and the second transmission group as the transmission member meshing between the output gear and the first gear. The transmission ratios between the multiple first transmission gears, the first transmission group, and the second transmission group are different, so as to change the number of teeth that the output gear rotates when the first gear rotates one week.

[0020] In a possible implementation, the rotating shaft includes a first rotating shaft, a second rotating shaft, a third rotating shaft, a fourth rotating shaft, and a fifth rotating shaft. The first rotating shaft is connected to the first gear. The second rotating shaft and the third rotating shaft are respectively connected to the first transmission gears. The fourth rotating shaft is connected to the output gear. The second rotating shaft is movably connected to the first mounting bracket so that the second rotating shaft can reciprocate along the axial direction.

[0021] The first transmission group includes a first sub-gear disposed on the first rotating shaft, a second sub-gear disposed on the fifth rotating shaft, a third sub-gear disposed on the second rotating shaft, and a fourth sub-gear disposed on the third rotating shaft. The second transmission group includes a fifth sub-gear disposed on the fifth rotating shaft, a sixth sub-gear disposed on the second rotating shaft, and a seventh sub-gear disposed on the third rotating shaft.

[0022] Driving the speed changer to drive the second rotating shaft to move along the axial direction. When the first transmission gears are meshed, it is in the first working state. The multiple first transmission gears, the first gear, and the output gear form a complete transmission chain.

[0023] In a possible implementation, the adjusting member includes a wrench, a first retaining piece, and a second retaining piece. The wrench is disposed on the second rotating shaft. The first retaining piece is disposed on the third rotating shaft. The second retaining piece is disposed on the fifth rotating shaft. Along the axial direction, the second retaining piece is located above the first retaining piece. Under the action of gravity, the wrench is located below the first retaining piece. When the first module is in the third working state, driving the wrench to abut against the first retaining piece, the first module is in the second working state. Driving the wrench to abut against the second retaining piece, the first module is in the first working state.

[0024] According to the adder provided by the embodiment of the present application, in the cooperation structure of the first module and the second module, through the arrangement of the paddle and multiple adjusting pieces, while driving the first gear to rotate, the second gear can rotate in a certain pattern. This specific rotation pattern can be adaptively adjusted according to the different number systems of the adder to be demonstrated, so that students can more intuitively observe the working mechanism of the adder in different number systems. To meet this requirement, the number of teeth rotated by the first gear, the preset angle rotated by the adjusting piece, and the preset number of teeth rotated by the second gear are combined. When the adder is in the N number system, the ratio of the preset number of teeth to the total number of teeth of the second gear is controlled to be 1 / N. In this way, when demonstrating the addition working mechanism in different number systems, only the number of teeth of the corresponding gear needs to be replaced, and the ratio of the preset number of teeth to the total number of teeth of the second gear is controlled to be 1 / N, which can enable students to more intuitively observe the addition principle in different number systems while being simple to operate and easy to implement.

Detailed implementation manners

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0033] Figure 1 The structural schematic diagram of an adder provided by an embodiment of the present application is shown, where the direction indicated by arrow L is the first direction. Figure 2 A simple schematic diagram of an adder provided by an embodiment of the present application is shown. Figure 3 The structural schematic diagram of another adder provided by an embodiment of the present application is shown.

[0034] See Figures 1 to 3 , an embodiment of the present application provides an adder, which can be a model built by building blocks for teaching. Such a detachable model can facilitate demonstrations according to different needs in teaching, so that students can more intuitively understand the working mechanism of the adder through the model of the adder. Or, it can also be directly made of components of relevant materials, which is not specifically limited herein. Taking the adder as a built model as an example, the adder will be described in detail below.

[0035] The adder includes a first module 1 and a second module 2 arranged in sequence along the first direction L. The adjacent modules are connected by an adjusting member 4. The adjusting member 4 includes a paddle 41 and a plurality of adjusting pieces 42 evenly distributed in the circumferential direction. There is a preset angle between any two adjacent adjusting pieces 42. The first module 1 includes a first gear 12, and the second module 2 includes a second gear 22. The rotation of the adjusting piece 42 can drive the rotation of the second gear 22, and the rotation of the first gear 12 can drive the rotation of the paddle 41. When the paddle 41 rotates one week with the first gear 12, the paddle 41 can push the plurality of adjusting pieces 42 to rotate a preset angle, thereby driving the second gear 22 to rotate a preset number of teeth. When the adder is an N -ary system, the ratio of the preset number of teeth to the total number of teeth of the second gear 22 is 1 / N.

[0036] It can be understood that the first module 1 and the second module 2 can be regarded as the units digit and the tens digit in addition. When it is necessary to demonstrate up to the hundreds digit, thousands digit, etc., multiple second modules 2 can be set, and they are arranged on one side of the first module 1 along the first direction L. The multiple second modules 2 are also connected by the adjusting member 4, and a paddle 41 is provided on the rotating shaft 5 corresponding to the second gear 22, and a plurality of adjusting pieces 42 are provided on the rotating shaft 5 corresponding to the input gear 23. When the first module 1 acts as the driving part, the second module 2 as the driven part acts accordingly under the action of the adjusting member 4, so that the second module 2 in the tens place, and even the second modules 2 in the hundreds place, thousands place... realize the addition number system. It can be known that the first module 1 is the driving part, and the subsequent second modules 2 connected in sequence are the driven parts, and the working principles of the multiple second modules 2 are the same. For the convenience of description, the following only takes the first module 1 and the second module 2 in the units digit and the tens digit as examples to elaborate on the specific structural cooperation and working principle of the adder in detail.

[0037] Optionally, the multiple modules are detachably connected to facilitate increasing or decreasing the number of digits of the model according to requirements, and no specific limitation is made here.

[0038] In the cooperation structure of the first module 1 and the second module 2, by providing the setting of the paddle 41 and multiple adjusting pieces 42, while driving the first gear 12 to rotate, the second gear 22 can rotate in a certain pattern. This specific rotation pattern can be adjusted adaptively according to the different number systems of the adder to be demonstrated, so that students can more intuitively observe the working mechanism of the adder in different number systems. To meet this requirement, the number of teeth rotated by the first gear 12, the preset angle of rotation of the adjusting piece 42, and the preset number of teeth rotated by the second gear 22 are combined. When the adder is in the N number system, the ratio of the preset number of teeth to the total number of teeth of the second gear 22 is controlled to be 1 / N. In this way, when demonstrating the addition working mechanism in different number systems, only the number of teeth of the corresponding gears needs to be replaced, and the ratio of the preset number of teeth to the total number of teeth of the second gear 22 is controlled within 1 / N, which can enable students to more intuitively observe the addition working principle in different number systems while being simple to operate and easy to implement.

[0039] In an alternative embodiment, the first module 1 includes a first mounting bracket 11. The first gear 12 is rotatably connected to the first mounting bracket 11 through a rotating shaft 5. The first module 1 further includes a plurality of first transmission gears 13 and an output gear 14 that are meshed along the first direction L. The first transmission gears 13 are meshed between the first gear 12 and the output gear 14. The first transmission gears 13 and the output gear 14 are respectively connected to the first mounting bracket 11 through the rotating shaft 5. The first gear 12 and the output gear 14 have the same number of teeth, and the rotation directions of the first gear 12 and the output gear 14 are opposite. The paddle 41 is connected to the rotating shaft 5 corresponding to the output gear 14. The rotation of the first gear 12 is transmitted to the output gear 14 through the provided first transmission gears 13 and rotates at the same speed, and is output to the second module 2 through the rotation of the first gear 12. In this cooperation structure, the number and the number of teeth of the meshed plurality of first transmission gears 13 can be adjusted adaptively according to requirements, as long as the first gear 12 and the output gear 14 have the same number of teeth, and no specific limitation is made here. The number of teeth of the first gear 12 and the output gear 14 can be set according to requirements, and no specific limitation is made here.

[0040] In an alternative embodiment, the second module 2 includes a second mounting bracket 21. The second gear 22 is rotatably connected to the second mounting bracket 21 by a rotating shaft 5. The second module 2 further includes an input gear 23 and a plurality of second transmission gears 24 that are meshed along the first direction L. The second transmission gears 24 are meshed between the second gear 22 and the input gear 23. The input gear 23 and the output gear 14 are arranged adjacent to each other. The input gear 23 and the second transmission gears 24 are respectively connected to the second mounting bracket 21 by the rotating shaft 5. The number of teeth of the input gear 23 and the second gear 22 is different. A plurality of adjusting pieces 42 are circumferentially arranged on the rotating shaft 5 corresponding to the input gear 23. In the mating structure of the second module 2, through the cooperating dial 41 and adjusting piece 42, the rotation of the output gear 14 is transmitted to the input gear 23. By using the number of teeth set on the input gear 23 and in cooperation with the preset angle of rotation of the adjusting piece 42, the meshed second gear 22 is rotated by a preset number of teeth. Through this mating structure, in the corresponding N - base system, when the first gear 12 rotates one full circle, the input gear 23 can drive the second gear 22 to rotate by an angle corresponding to 1 / N teeth. By simply adjusting the corresponding number of teeth and angle, the manufacturing requirements of different number systems can be met, and the operation is simple and convenient.

[0041] It can be understood that the first mounting bracket 11 and the second mounting bracket 21 can be detachably connected through a connecting portion 3, which will not be elaborated here.

[0042] Optionally, the number of teeth of the first gear 12 is the same as that of the second gear 22, and the number of teeth of the second gear 22 is different from that of the input gear 23. When the first gear 12 rotates one full circle and drives the dial 41 to rotate one full circle, under the drive of the adjusting piece 42, the input gear 23 rotates a preset angle, and the number of teeth corresponding to the preset angle of rotation of the input gear 23 is the preset number of teeth. Thus, under the drive of the meshed second transmission gear 24, the second gear 22 is driven to rotate by the preset number of teeth.

[0043] It can be understood that the number of gears directly meshed between the first gear 12 and the second gear 22 is odd to avoid misalignment of the rotation direction.

[0044] In an alternative embodiment, the adder is binary. The first gear 12 is driven to rotate two full circles, the first transmission gear 13 drives the output gear 14 to rotate in the opposite direction for two full circles, the dial 41 rotates two full circles accordingly, and the cooperating adjusting piece 42 rotates by 2 times the preset angle, thereby driving the second gear 22 to rotate one full circle.

[0045] Taking the adder as decimal as an example below, the specific structural cooperation of the first module 1 and the second module 2 will be described in detail.

[0046] The first gear 12, the second gear 22, and the output gear 14 in the first module 1 and the second module 2 are all set to 40 teeth, the first transmission gear 13, the second transmission gear 24, and the input gear 23 are set to 24 teeth, the number of the adjustment pieces 42 is 6, and the preset angle is 60°, which can save space while transmitting the rotation speed without speed loss, and the rotation directions of the first gear 12 and the output gear 14 are opposite. The output gear 14 is connected to the paddle 41, and the input gear 23 is connected to multiple adjustment pieces 42.

[0047] On this basis, at least a roller with scales 1-10 can be added to the first gear 12 and the second gear 22. Since the second gear 22 has a total of 40 teeth, each scale corresponds to 40 / 10=4 teeth. Every time the first gear 12 rotates one circle, the paddle 41 triggers the adjustment plate 42 to rotate 60°. For the 24-tooth input gear 23 that rotates 60°, it rotates 4 teeth. Under the action of the second transmission gear 24, the second gear 22 rotates 4 teeth, which is exactly one scale. When the first gear 12 rotates 10 circles in sequence, the second gear 22 as the tens position has just rotated a full circle, and will advance one scale as a carry. The first gear 12 in the ones position will rotate back to scale 1 to continue the addition operation.

[0048] Optionally, the number of the plurality of adjustment pieces 42 is 6, and along the circumference of the rotating shaft 5, the preset angle between any adjacent adjustment pieces 42 is 60°. Alternatively, the number of the adjustment pieces 42 may be set to other numbers, as long as the input gear 23 can rotate the required number of teeth according to the rotation angle, and no specific limitation is made here.

[0049] Optionally, the paddle 41 is provided with a protrusion 411, and when the rotating shaft 5 drives the paddle 41 to rotate, the protrusion 411 can extend between adjacent adjustment pieces 42, and as the rotating shaft 5 rotates, the protrusion 411 can abut against the adjustment piece 42 to push the adjustment piece 42 to rotate a preset angle. For example, the paddle 41 can be set to a water drop-shaped structure, which is not specifically limited here.

[0050] It is understandable that the adder can also be adjusted to hexadecimal, octal, or other bases, as long as the gears in the first module 1 and the second module 2 can be adjusted accordingly according to the above description, and examples are not given here one by one.

[0051] In an alternative embodiment, see Figure 3 and Figure 4, the first module 1 further includes a first transmission group 7, a second transmission group 8, and a speed-changing member 6. The speed-changing member 6 can select one of a plurality of first transmission gears 13, the first transmission group 7, and the second transmission group 8 as a transmission member for meshing between the output gear 14 and the first gear 12. The transmission ratios between the plurality of first transmission gears 13, the first transmission group 7, and the second transmission group 8 are different, so as to change the number of teeth that the output gear 14 rotates when the first gear 12 rotates one week. By providing the first transmission group 7 and the second transmission group 8, the transmission speed and transmission ratio of the gears in the first module 1 can be adjusted. While achieving speed change, the number of teeth that the corresponding output gear 14 rotates when the first gear 12 rotates one week can be adjusted, thereby adjusting the number system of the adder.

[0052] Specifically, the rotating shaft 5 includes a first rotating shaft 51, a second rotating shaft 52, a third rotating shaft 53, a fourth rotating shaft 54, and a fifth rotating shaft 55. The first rotating shaft 51 is connected to the first gear 12. The second rotating shaft 52 and the third rotating shaft 53 are respectively connected to the first transmission gears 13. The fourth rotating shaft 54 is connected to the output gear 14. The second rotating shaft 52 is movably connected to the first mounting bracket 11 so that the second rotating shaft 52 can reciprocate along the axial direction. The first transmission group 7 includes a first sub-gear 71 provided on the first rotating shaft 51, a second sub-gear 72 provided on the fifth rotating shaft 55, a third sub-gear 73 provided on the second rotating shaft 52, and a fourth sub-gear 74 provided on the third rotating shaft 53. The second transmission group 8 includes a fifth sub-gear 81 provided on the fifth rotating shaft 55, a sixth sub-gear 82 provided on the second rotating shaft 52, and a seventh sub-gear 83 provided on the third rotating shaft 53.

[0053] When the driving speed-changing member 6 drives the second rotating shaft 52 to move along the axial direction until the first transmission gears 13 are meshed, it is in the first working state. A complete transmission chain is formed among the plurality of first transmission gears 13, the first gear 12, and the output gear 14. When the first sub-gear 71, the second sub-gear 72, the third sub-gear 73, and the fourth sub-gear 74 are meshed, it is in the second working state. A complete transmission chain is formed among the first transmission group 7, the first gear 12, and the output gear 14. When the first sub-gear 71, the second sub-gear 72, the fifth sub-gear 81, the sixth sub-gear 82, and the seventh sub-gear 83 are meshed, it is in the third working state. A complete transmission chain is formed among the second transmission group 8, the first gear 12, and the output gear 14.

[0054] In different working states, the speed ratio between the first gear 12 and the output gear 14 can be achieved according to the specific combination form of the mating transmission gears. The first transmission gears 13 are transmitted at a constant speed. The speed of the output gear 14 changed by the first transmission group 7 and the second transmission group 8 can be higher or lower than that of the first gear 12. It can be adjusted by changing the number of teeth of the mating sub-gears according to actual requirements, and no specific limitation is made here.

[0055] In an alternative embodiment, the speed changer 6 includes a wrench 61, a first retaining piece 62, and a second retaining piece 63. The wrench 61 is disposed on the second rotating shaft 52, the first retaining piece 62 is disposed on the third rotating shaft 53, and the second retaining piece 63 is disposed on the fifth rotating shaft 55. Along the axial direction, the second retaining piece 63 is located above the first retaining piece 62. Under the action of gravity, the wrench 61 is located below the first retaining piece 62. When the first module 1 is in the third working state and drives the wrench 61 to abut against the first retaining piece 62, the first module 1 is in the second working state. When the first module 1 drives the wrench 61 to abut against the second retaining piece 63, the first module 1 is in the first working state.

[0056] It can be understood that the first transmission group 7, the second transmission group 8, and the speed changer 6 can also adopt other cooperation structures to achieve the purpose, or may further include a third transmission group, a fourth rotating group, etc., as long as it can adjust the transmission ratio of the first module 1, and further adjust the number of teeth that the output gear 14 rotates when the first gear 12 rotates one week, which can be used to adjust the carry radix of the adder, and no specific limitation is made here.
