TECHNICAL FIELD
[0001] The present application relates to the motor technical field, and in particular to a positive and negative rotation double-rotor energy collector. BACKGROUND
[0002] Commonly, the generator is composed of a stator, a rotor, an end cover, a machine base and a bearing. The stator and the rotor of the generator are connected and assembled through the bearing, the machine base and the end cover, so that the rotor can rotate in the stator, and a certain excitation current is input through a slip ring, so that the rotor becomes a rotating magnetic field, the stator coil makes a cutting magnetic force line movement, thereby generating an induced electromotive force, which is led out through the terminal and connected to the circuit, so as to generate a current.
[0003] Specifically, the amount of electricity generated by cutting the magnetic field lines is proportional to the relative rotation speed formed between the rotor and the stator, and the greater the relative rotation speed, the greater the power generation. However, in the field of low-speed power generation, although the stator and the rotor can be rotated and the two are counter-rotated to increase the relative rotation speed of the two, at least one of the following problems occurs in the related art: only the rotor and the stator are counter-rotated at the same speed, and the power generation efficiency of the generator in the low-speed power generation field is not further improved, thereby reducing the collection efficiency of the generated energy in the power generation process. SUMMARY
[0004] The problem solved by the present application is that only the rotor and the stator are counter-rotated at the same speed, and the power generation efficiency of the generator in the low-speed power generation field is not further improved, thereby reducing the collection efficiency of the generated energy in the power generation process.
[0005] To solve the above problems, the present application provides a positive and negative rotation double-rotor energy collector, comprising: a first rotor, which is internally provided with a first containing space; a second rotor, which is coaxially arranged with the first rotor and internally provided with the first containing space; and a multi-stage transmission assembly, which is in transmission connection with the first rotor and the second rotor; and when the first rotor rotates in a first direction at a first rotation speed, the second rotor rotates in a second direction opposite to the first direction at a second rotation speed through the multi-stage transmission assembly; wherein the first rotation speed is n1, the second rotation speed is n2, n2=k*n1, k is a rotation speed coefficient, and k>1 or 0
[0006] Compared with the prior art, the technical effects achieved by the technical scheme are: on the basis of the related technical scheme, the single-stage transmission of the bevel gear is replaced by the multi-stage transmission assembly, so that the rotational speed of the first rotor is not equal to the rotational speed of the second rotor, that is, the relative rotational speed of the first rotor and the second rotor is greater than 2 times the minimum rotational speed of the first rotor or the second rotor. Specifically, in a specific example, k can be 2, so n2 = 2n1, that is, the rotational speed of the second rotor is 2 times the rotational speed of the first rotor. Since the first rotor and the second rotor rotate in opposite directions, the relative rotational speed of the first rotor and the second rotor is 3n1, that is, the relative rotational speed is 3 times the rotational speed of the first rotor. Therefore, under the premise of ensuring that the rotational speed of the first rotor remains unchanged, the rate at which the positive and negative rotation double-rotor energy collector cuts the magnetic field is increased by two times, and even compared with the generator in which the stator and the rotor rotate in opposite directions, the rate at which the magnetic field is cut is also improved, further improving the power generation efficiency in the low-speed power generation field, thereby improving the energy collection efficiency.
[0007] In an example of the present application, the first rotor comprises: a first mounting shell; a second mounting shell arranged on the axis of the first mounting shell, and a magnetic field mounting position is formed between the first mounting shell and the second mounting shell; a magnetic assembly arranged in the magnetic field mounting position; wherein the second rotor is clamped between the first mounting shell and the second mounting shell, and when the first rotor and the second rotor move, the magnetic field lines formed by the magnetic assembly are cut.
[0008] Compared with the prior art, the technical effects achieved by the technical scheme are: since the magnetic assembly is arranged on the first rotor, as the first rotor rotates, the magnetic field lines of the electromagnetic field formed by the magnetic assembly are cut by the second rotor during the relative rotation of the second rotor and the first rotor, thereby making the induced current more stable. Specifically, by avoiding arranging the magnetic field on the first rotor and the second rotor respectively, when the relative motion between the first rotor and the second rotor is unstable, the magnetic field is easily in an unstable state, thereby reducing the efficiency of cutting the magnetic field lines to generate induced electricity. For example, when either the first rotor or the second rotor is in a stopped state, the first rotor and the second rotor can only cut the magnetic field lines when the magnetic assembly is paired to form a magnetic field. In the present technical scheme, the first mounting shell and the second mounting shell are integrally formed, thereby ensuring the stability of the electromagnetic field formed by the magnetic assembly after the magnetic assembly is installed. Therefore, whether only the first rotor is rotating or only the second rotor is rotating, uninterrupted cutting of the magnetic field lines can be ensured, uninterrupted generation of electricity is achieved, and the power generation efficiency is greatly improved.
[0009] In one example of the present application, the magnetic assembly comprises a first magnetic assembly and a second magnetic member, the first magnetic assembly is arranged on the first mounting shell near the side of the second mounting shell; the second magnetic member is arranged on the second mounting shell near the side of the first mounting shell, and the first magnetic assembly and the second magnetic member are opposite to each other; wherein the second rotor is provided with a conductive coil clamped between the first magnetic assembly and the second magnetic member.
[0010] Compared with the prior art, the technical effects achieved by the technical scheme are: the magnetic field formed by the combination of the first magnetic assembly and the second magnetic member has a simple structure, and the magnetic assembly can be detachably mounted on the first rotor according to the actual situation, thereby facilitating replacement.
[0011] In one example of the present application, the side of the first mounting shell near the second mounting shell is provided with m1 first mounting positions, the m1 first mounting positions are arranged at equal intervals around the axis, and the first mounting positions are arranged in cooperation with the first magnetic assembly; the side of the second mounting shell near the first mounting shell is provided with m2 second mounting positions, the m2 second mounting positions are arranged at equal intervals around the axis, and the second mounting positions are arranged in cooperation with the second magnetic member; wherein m1 and m2 are both constants greater than 0.
[0012] Compared with the prior art, the technical effects achieved by the technical scheme are: in one specific example, m1 can be 8, and accordingly, the number of first mounting positions is 8, and since the m1 first mounting positions are arranged at equal intervals, the first magnetic assemblies mounted in cooperation with them are also arranged at equal intervals. On the contrary, m2 is 4, so that the number of second magnetic members connected in cooperation with the second mounting positions is also 4. It can be understood that the diameter of the first mounting shell is greater than the diameter of the second mounting shell, so that the circumference diameter surrounded by the m2 second mounting positions is smaller than the circumference diameter surrounded by the m1 first mounting positions. Therefore, in order to ensure that the first rotor and the second rotor are always in the state of cutting magnetic field lines to generate induced current during mutual movement, the number of first mounting positions is set to be greater than the number of second mounting positions, so as to ensure that as many magnetic lines as possible emitted by the second magnetic member can be received by the first magnetic assembly, thereby avoiding intermittent generation of current and reducing the overall power generation efficiency in the limited first accommodation space; in addition, by arranging the first mounting positions and the second mounting positions at equal intervals respectively, the first rotor can be kept in a stable state during rotation, avoiding the risk of overturning caused by the eccentric arrangement of the first rotor after mounting a plurality of first magnetic assemblies and second magnetic members, which is not conducive to the stable operation of the positive and negative rotation dual-rotor energy collector.
[0013] In one example of the present application, the first magnetic component comprises: a third magnetic piece, which is arranged opposite to the corresponding second magnetic piece, and the two are parallel to each other and attract each other; at least one fourth magnetic piece, which is arranged adjacent to the third magnetic piece, and the fourth magnetic piece is arranged obliquely relative to the second magnetic piece, and the fourth magnetic piece and the second magnetic piece attract each other; wherein the at least one fourth magnetic piece and the second magnetic piece form an included angle of α on the side close to each other.
[0014] Compared with the prior art, the technical effects achieved by adopting the technical scheme are as follows: α can be taken as 45°, so as to make the effective magnetic field formed between the first magnetic component and the corresponding second magnetic piece as large as possible, thereby realizing effective and continuous adjacent magnetic field, that is, the magnetic field formed in the first rotor is continuously arranged around the rotation axis, thereby ensuring the overall power generation efficiency of the motor.
[0015] In one example of the present application, the number of the second magnetic pieces is multiple, and at least one of the second magnetic pieces close to the side of the axis is N-pole, and at least one of the second magnetic pieces adjacent to the N-pole and close to the side of the axis is S-pole.
[0016] Compared with the prior art, the technical effects achieved by adopting the technical scheme are as follows: avoiding the magnetic cancellation between the adjacent second magnetic pieces arranged in the same magnetic arrangement, thereby weakening the overall magnetic field strength of the motor, and thereby reducing the power generation efficiency.
[0017] In one example of the present application, the surface of the second rotor is provided with a plurality of mounting grooves for mounting the conductive coils, and the plurality of mounting grooves are arranged at equal intervals.
[0018] Compared with the prior art, the technical effects achieved by adopting the technical scheme are as follows: the stable rotation of the second rotor can be ensured, and the stable and uniform transmission of the current generated by the cutting magnetic field line can be ensured.
[0019] In one example of the present application, the number of the conductive coils is multiple, and the conductive coils are arranged one by one corresponding to the mounting grooves; wherein the plurality of conductive coils are connected in series and / or parallel to each other.
[0020] Compared with the prior art, the technical effects achieved by adopting the technical scheme are as follows: the conductive coils can be connected in series to output a larger voltage; correspondingly, the conductive coils can be connected in parallel to output a larger current. Thus, different actual needs can be met.
[0021] In an example of the present application, the multi-stage transmission assembly comprises: a bracket assembly arranged near a first end of the second rotor; a first input shaft assembly arranged in the bracket assembly, and the first input shaft assembly is rotationally connected with the second rotor; a first gear assembly connected with the first input shaft assembly; at least two second output shaft assemblies arranged in the bracket assembly; a second gear assembly connected with the second output shaft assembly, the second gear assembly is engaged with the first gear assembly, and the second gear assembly is drivingly connected with the first rotor.
[0022] Compared with the prior art, the technical effects achieved by the technical scheme are: the multi-stage transmission assembly has a simple structure and is convenient to replace.
[0023] In an example of the present application, the bracket assembly is provided with oppositely arranged first and second support seats, one end of the first input shaft assembly is rotationally connected with the first support seat away from the second rotor, and the other end is rotationally connected with the second rotor; wherein the second support seat is provided with a mounting hole through which the first input shaft assembly passes; the second gear assembly comprises: a second transmission gear one arranged in any one of the at least two second output shaft assemblies, and the second transmission gear one is engaged with a first transmission gear one of the first gear assembly; a second transmission gear assembly three drivingly connected with the first rotor through a connecting piece arranged in the mounting hole; and a second transmission gear assembly two arranged in the other of the at least two second output shaft assemblies, and the second transmission gear assembly two is engaged with the second transmission gear assembly three.
[0024] Compared with the prior art, the technical effects achieved by the technical scheme are: the multi-stage transmission assembly has a simple structure and is convenient to replace, and under the condition of ensuring the overall size of the forward and reverse double-rotor energy collector, the installation space formed by the bracket assembly is fully utilized to effectively increase the power generation efficiency.
[0025] After adopting the technical scheme of the present application, the following technical effects can be achieved:
[0026] (1) k can be taken as 2, then n2=2n1, that is, the rotational speed of the second rotor is twice that of the first rotor, and since the first rotor and the second rotor rotate in opposite directions, the relative rotational speed of the first rotor and the second rotor is 3n1, that is, the relative rotational speed is 3 times the rotational speed of the first rotor. Thus, under the premise of ensuring the rotational speed of the first rotor, the rate at which the forward and reverse double-rotor energy collector cuts the magnetic field is doubled, and even compared with the generator in which the stator and the rotor rotate in opposite directions, the rate at which the magnetic field is cut is also improved, further improving the power generation efficiency in the low-speed power generation field;
[0027] (2) Avoid setting the magnetic field on the first rotor and the second rotor respectively, which leads to the magnetic field in unstable state when the relative motion between the first rotor and the second rotor is unstable, thereby reducing the efficiency of cutting the magnetic field line to generate induced electricity. For example, when one of the first rotor and the second rotor is in a stop running state, only the first rotor and the second rotor can be cut to move the magnetic field line when the magnetic assembly is paired to form a magnetic field. In the technical solution, the first mounting shell and the second mounting shell are integrally formed, so that the stability of the electromagnetic field formed by the magnetic assembly can be ensured after the magnetic assembly is installed. Therefore, whether only the first rotor is rotating or only the second rotor is rotating, the cutting magnetic field line can be ensured to be uninterrupted, the electricity generation is realized to be uninterrupted, and the power generation efficiency is greatly improved;
[0028] (3) The number of first installation positions is greater than the number of second installation positions, so that the magnetic lines radiated by the second magnetic member can be received by the first magnetic assembly as much as possible, thereby ensuring that in the limited first containing space, the intermittent generation of electric current is avoided to reduce the overall power generation efficiency. In addition, by equally spacing the first installation positions and the second installation positions, the first rotor can be in a stable state during rotation, avoiding the risk of overturning caused by the eccentricity of the first rotor during rotation after the first rotor is installed with multiple first magnetic assemblies and second magnetic members.

DETAILED DESCRIPTION
[0036] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0037] Embodiment one:
[0038] Reference is made to Figure 1 , which is a structural schematic view of a positive and negative rotation double-rotor energy collector 100 provided by the embodiment one of the present application. In combination with Figures 2-5 , the positive and negative rotation double-rotor energy collector 100 comprises, for example, a first rotor 10, a second rotor 20 and a multi-stage transmission assembly 30. The first rotor 10 is provided with a first accommodating space 11; the second rotor 20 is coaxially arranged with the first rotor 10, and the second rotor 20 is arranged in the first accommodating space 11; the multi-stage transmission assembly 30 is transmissionally connected with the first rotor 10 and the second rotor 20, and when the first rotor 10 rotates in a first direction at a first rotation speed, the second rotor 20 rotates in a second direction opposite to the first direction at a second rotation speed through the multi-stage transmission assembly 30; wherein the first rotation speed is n1, the second rotation speed is n2, n2=k×n1, k is a rotation speed coefficient, and k>1 or 0<k<1.
[0039] For example, a common generator is designed by a bevel gear assembly transmission to make the stator of the generator also rotate, specifically, the rotating direction of the stator is opposite to the rotor so as to increase the relative rotating speed of the two, thereby increasing the rate of cutting magnetic field lines and increasing the generated electric quantity. However, in this way, it is difficult to further improve the power generation of the generator, that is, it is difficult to realize that the relative rotating speed of the stator and the rotor is greater than 2 times.
[0040] Therefore, on the basis of the related technical solutions, the technical solutions replace the single-stage transmission of the bevel gear with the multi-stage transmission assembly 30, so that the rotation speed of the first rotor 10 is not equal to the rotation speed of the second rotor 20 by virtue of the action of the multi-stage transmission assembly 30, that is, the relative rotation speed of the first rotor 10 and the second rotor 20 is greater than 2 times the minimum rotation speed of the first rotor 10 or the second rotor 20. Specifically, in a specific example, k can be 2, and n2 = 2n1, that is, the rotation speed of the second rotor 20 is 2 times the rotation speed of the first rotor 10. Since the first rotor 10 and the second rotor 20 rotate in opposite directions, the relative rotation speed of the first rotor 10 and the second rotor 20 is 3n1, that is, the relative rotation speed is 3 times the rotation speed of the first rotor 10. Therefore, under the premise of ensuring the rotation speed of the first rotor 10, the positive and negative rotation double-rotor energy collector 100 can increase the rate of cutting the magnetic field by two times, and even more than the generator with the same large opposite rotating stator and rotor, the rate of cutting the magnetic field is improved, which further improves the power generation efficiency in the low-speed power generation field.
[0041] Preferably, the first rotor 10 comprises a first mounting shell 12, a second mounting shell 13, and a magnetic assembly 14. The second mounting shell 13 is arranged at the axial position of the first mounting shell 12, and a magnetic field mounting position is formed between the first mounting shell 12 and the second mounting shell 13; the magnetic assembly 14 is arranged in the magnetic field mounting position; wherein the second rotor 20 is clamped between the first mounting shell 12 and the second mounting shell 13, and the first rotor 10 and the second rotor 20 cut the magnetic field lines formed by the magnetic assembly 14 when moving.
[0042] Specifically, since the magnetic assembly 14 is arranged on the first rotor 10, with the rotation of the first rotor 10, the magnetic field lines of the electromagnetic field formed by the magnetic assembly 14 are cut by the second rotor 20 during the relative rotation between the second rotor 20 and the first rotor 10, so that the induced current is more stable. Specifically, by avoiding arranging the magnetic field on the first rotor 10 and the second rotor 20 respectively, when the relative motion between the first rotor 10 and the second rotor 20 is unstable, the magnetic field is easily in an unstable state, thereby reducing the efficiency of cutting the magnetic field lines to generate the induced current. For example, when either of the first rotor 10 and the second rotor 20 is in a stop running state, the first rotor 10 and the second rotor 20 can only cut the magnetic field lines when the magnetic assembly 14 is paired to form a magnetic field. In the technical solution, the first mounting shell 12 and the second mounting shell 13 are integrally formed, so that after the magnetic assembly 14 is installed, the stability of the electromagnetic field formed by the magnetic assembly 14 is ensured. Therefore, whether only the first rotor 10 is rotating or only the second rotor 20 is rotating, cutting the magnetic field lines can be ensured to be uninterrupted, the power generation is uninterrupted, and the power generation efficiency is greatly improved.
[0043] Preferably, the magnetic assembly 14, for example, includes a first magnetic assembly 141 and a second magnetic member 142, the first magnetic assembly 141 is arranged on the side of the first mounting shell 12 close to the second mounting shell 13, the second magnetic member 142 is arranged on the side of the second mounting shell 13 close to the first mounting shell 12, and the first magnetic assembly 141 and the second magnetic member 142 are opposite in nature and attract each other; wherein the second rotor 20 is provided with a conductive coil 22 clamped between the first magnetic assembly 141 and the second magnetic member 142.
[0044] For example, when the first rotor 10 and the second rotor 20 rotate relatively, the second rotor 20 cuts the magnetic field lines of the magnetic field formed by the magnetic assembly 14, thereby generating an induced current, and then the induced current is transmitted out through the conductive coil 22.
[0045] Of course, the magnetic assembly 14 can be a magnet or an energized electromagnet.
[0046] Preferably, the side of the first mounting shell 12 close to the second mounting shell 13 is provided with m1 first mounting positions, the m1 first mounting positions are arranged at equal intervals around the axis of the first mounting shell 12, and the first mounting positions are arranged in cooperation with the first magnetic assembly 141; the side of the second mounting shell 13 close to the first mounting shell 12 is provided with m2 second mounting positions, the m2 second mounting positions are arranged at equal intervals around the axis of the first mounting shell 12, and the second mounting positions are arranged in cooperation with the second magnetic member 142; wherein m1 and m2 are both constants greater than 0.
[0047] In one embodiment, m1 can be 8, for example, and the number of first mounting positions is 8. Since the m1 first mounting positions are arranged at equal intervals, the first magnetic components 141 mounted in the first mounting positions are also arranged at equal intervals. In contrast, m2 can be 4, for example, and the number of second magnetic components 142 mounted in the second mounting positions is 4. It can be understood that the diameter of the first mounting housing 12 is greater than the diameter of the second mounting housing 13, so that the circumference of the m2 second mounting positions is smaller than the circumference of the m1 first mounting positions. Therefore, in order to ensure that the first rotor 10 and the second rotor 20 can always cut the magnetic field lines to generate induced current during rotation, the number of first mounting positions is greater than the number of second mounting positions, so that the magnetic lines emitted by the second magnetic components 142 can be received by the first magnetic components 141 as much as possible, thereby ensuring that the power generation efficiency is not reduced due to intermittent current generation in the limited first accommodating space 11. In addition, by arranging the first mounting positions and the second mounting positions at equal intervals, respectively, the first rotor 10 can be in a stable state during rotation, and the eccentricity of the first rotor 10 after mounting the plurality of first magnetic components 141 and second magnetic components 142 does not cause the first rotor 10 to shake during rotation, which is not conducive to stable operation of the forward and reverse rotation energy collector 100. In addition, the risk of overturning is reduced.
[0048] Preferably, the first magnetic component 141 includes a third magnetic component and at least one fourth magnetic component. The third magnetic component is arranged opposite to the corresponding second magnetic component 142, and the third magnetic component and the second magnetic component 142 are parallel to each other and attract each other. The at least one fourth magnetic component is arranged adjacent to the third magnetic component, and the fourth magnetic component is arranged obliquely relative to the second magnetic component 142. The fourth magnetic component and the second magnetic component 142 attract each other. The side surface of the at least one fourth magnetic component close to the second magnetic component 142 forms an angle α.
[0049] On the basis of the above specific examples, it can be understood that the value of a is related to the arrangement position between the plurality of fourth magnetic members and the second magnetic member 142. When the shape and size of the fourth magnetic members and the second magnetic member 142 are the same, when the number of fourth magnetic members is more, the range of a formed between the plurality of fourth magnetic members and the same second magnetic member 142 is larger, for example, from 45°<a<90° to 20°<a<90°. At the same time, it can be understood that as a decreases, the spacing between the plurality of fourth magnetic members arranged adjacent to each other decreases, that is, the magnetic field line arrangement formed by the magnetic assembly 14 is more uniform, thereby increasing the induced current generated by the cutting magnetic field line, thereby making the energy collected more, and improving the energy harvesting efficiency. Of course, in other words, by making the effective magnetic field formed between the first magnetic assembly 141 and the corresponding second magnetic member 142 as large as possible, the effective continuity with the adjacent magnetic field is realized, that is, the magnetic field formed in the first rotor 10 is continuously arranged around the rotation axis, thereby ensuring the power generation efficiency of the positive and negative rotation double-rotor energy harvester 100, thereby meeting the power generation and energy collection needs. Preferably, the number of second magnetic members 142 is more, and at least one second magnetic member 142 near the side of the axis of the first mounting shell 12 is N-pole, and at least one second magnetic member 142 arranged adjacent to it near the side of the axis of the first mounting shell 12 is S-pole. Avoiding the same magnetic arrangement of the adjacent second magnetic members 142 leading to mutual magnetic cancellation and weakening the overall magnetic field strength of the motor, thereby reducing the power generation efficiency.
[0050] Preferably, the surface of the second rotor 20 is provided with a plurality of mounting grooves for mounting the conductive coil 22, and the plurality of mounting grooves are arranged at equal intervals.
[0051] Preferably, the number of conductive coils 22 is more, and the conductive coils 22 are arranged one-to-one corresponding to the mounting grooves; wherein the plurality of conductive coils 22 are in series and / or parallel with each other.
[0052] In one specific example, the conductive coils 22 can be in series with each other to output a larger voltage; correspondingly, the conductive coils 22 can be in parallel with each other to output a larger current. Thus, different actual needs can be met.
[0053] Preferably, the multi-stage transmission assembly 30 comprises, for example, a bracket assembly 40, a first input shaft assembly 37, a first gear assembly, a second gear assembly and at least two second output shaft assemblies. The bracket assembly 40 is arranged at the first end of the second rotor 20 close to the second magnetic member 142; the first input shaft assembly 37 is arranged on the bracket assembly 40 of the second magnetic member 142, and the first input shaft assembly 37 of the second magnetic member 142 is rotationally connected with the second rotor 20 of the second magnetic member 142; the first gear assembly is connected with the first input shaft assembly 37 of the second magnetic member 142; the at least two second output shaft assemblies are arranged on the bracket assembly 40 of the second magnetic member 142; the second gear assembly is connected with the second output shaft assemblies of the second magnetic member 142, the second gear assembly of the second magnetic member 142 is engaged with the first gear assembly of the second magnetic member 142, and the second gear assembly of the second magnetic member 142 is drivingly connected with the first rotor 10 of the second magnetic member 142.
[0054] Preferably, the bracket assembly 40 is provided with oppositely arranged first and second support seats 41 and 42. One end of the first input shaft assembly 37 is rotationally connected with the first support seat 41 away from the second rotor 20, and the opposite end of the first input shaft assembly 37 is rotationally connected with the second rotor 20; wherein the second support seat 42 is provided with a mounting hole for the first input shaft assembly 37 to pass through; the second gear assembly comprises, for example, a second transmission gear one 32, a second transmission gear assembly three and a second transmission gear assembly two.
[0055] Specifically, the second transmission gear one 32 is arranged on any one of the at least two second output shaft assemblies of the second magnetic member 142, and the second transmission gear one 32 of the second magnetic member 142 is engaged with the first transmission gear one 31 of the first gear assembly of the second magnetic member 142; the second transmission gear assembly three is drivingly connected with the first rotor 10 of the second magnetic member 142 through the connecting member 43 arranged in the mounting hole of the second magnetic member 142; the second transmission gear assembly two is arranged on the other of the at least two second output shaft assemblies of the second magnetic member 142, and the second transmission gear assembly two of the second magnetic member 142 is engaged with the second transmission gear assembly three of the second magnetic member 142.
[0056] In one specific example, the forward and reverse rotation double-rotor energy collector 100 comprises, for example, a support base, the first rotor 10, the second rotor 20 and the multi-stage transmission assembly 30 are all arranged on the support base, the bracket assembly 40 is provided with a bearing for cooperating with the first input shaft assembly 37, similarly, the bracket assembly 40 is also provided with a bearing for cooperating with the second output shaft assembly, in addition, in order to facilitate the distinction, the number of the second output shaft assemblies can be two, and are respectively a second output shaft assembly one 38 and a second output shaft assembly two 39, and the first input shaft assembly 37, the second output shaft assembly one 38 and the second output shaft assembly two 39 are arranged in parallel with each other.
[0057] Specifically, the second transmission gear one 32 is arranged on the second output shaft assembly one 38, and the second transmission gear assembly two is arranged on the second output shaft assembly two 39. The second output shaft assembly one 38 is further provided with the second transmission gear four 33 coaxially arranged with the second transmission gear one 32. The second transmission gear assembly three is provided with the second transmission gear five 34 engaged with the second transmission gear four 33, the second transmission gear six 35 coaxially arranged with the second transmission gear five 34, and the second transmission gear seven 36 engaged with the second transmission gear six 35. The second transmission gear seven 36 is sleeved on the first input shaft assembly 37, and the second transmission gear seven 36 is in transmission connection with the first rotor 10.
[0058] Further, it can be understood that, for example, the first transmission gear one 31 can be taken as clockwise rotation, thereby synchronously driving the second rotor 20 in transmission connection therewith to rotate clockwise, and then the first transmission gear one 31 drives the second transmission gear one 32 engaged therewith to rotate counterclockwise, thereby driving the second transmission gear four 33 coaxially arranged therewith to also rotate counterclockwise. Further, the second transmission gear four 33 drives the second transmission gear five 34 engaged therewith to rotate clockwise, and then the second transmission gear five 34 drives the second transmission gear six 35 coaxially arranged therewith to also rotate clockwise. Finally, the second transmission gear six 35 drives the second transmission gear seven 36 engaged therewith to rotate counterclockwise. Since the second transmission gear seven 36 is in transmission connection with the first rotor 10, the first rotor 10 is also driven to rotate counterclockwise in the direction opposite to that of the second rotor 20. Thus, the reverse rotation of the first rotor 10 and the second rotor 20 is finally realized.
[0059] In a specific example, the number of teeth of the first transmission gear one 31 is taken as 30, the number of teeth of the second transmission gear one 32 is taken as 10, the number of teeth of the second transmission gear four 33 is taken as 25, the number of teeth of the second transmission gear five 34 is taken as 15, the number of teeth of the second transmission gear six 35 is taken as 25, and the number of teeth of the second transmission gear seven 36 is taken as 25. Thus, the rotation speed n1 of the first rotor 10 is finally taken as 5n2, that is, k is taken as 0.2. At this time, the rotation speed of the first rotor 10 is 5 times that of the second rotor 20. Thus, the overall power generation efficiency of the motor is greatly improved.
[0060] In addition, the positive and negative rotation double-rotor energy collector 100 is provided with an energy collection device 50. The energy collection device 50 is arranged at one end of the motor composed of the first rotor 10 and the second rotor 20. Specifically, the energy collection device 50 is arranged at the end of the motor away from the multi-stage transmission assembly 30, and the energy collection device 50 is used to collect the induced current generated by the reverse rotation of the first rotor 10 and the second rotor 20 to cut the magnetic field lines, thereby playing a role of collecting energy, so as to supply power to other electric appliances.
[0061] Although the present application has been disclosed with reference to the above embodiments, the application is not limited to the above embodiments. It will be apparent to those skilled in the art that various modifications and changes can be made thereto without departing from the spirit and scope of the application. The scope of the application should be limited only by the appended claims.
