Description

Technical Field

[0001] The present invention relates to the technical field of gyroscopes, and in particular to a gyroscope and a charging device. Background Art

[0002] A gyroscope refers to a rigid body that rotates at high speed around a fulcrum. It is one of the earliest entertainment tools among the Chinese people. To this day, gyroscopes are still popular among the general public. It can be said that there are people of all ages who love gyroscopes.

[0003] In the related art, after the gyroscope is rotated by external force, the rotation time is not long. The gyroscope will soon stop rotating due to the friction of the rotating plane or other resistance. If the gyroscope needs to be rotated repeatedly, the external force needs to be repeatedly applied to the gyroscope. For existing gyroscope players, frequent operation is not only physically demanding, but also troublesome, resulting in a very bad experience for gyroscope players. To address this problem, an electric gyroscope has appeared on the market, which uses the rotation of a motor to drive the gyroscope to rotate continuously.

[0004] However, the existing electric gyroscope needs to be turned on or off by flipping or pressing a button on the gyroscope shell, which not only damages the appearance of the gyroscope shell, but also makes the operation more troublesome.

[0025] According to the gyroscope and charging device of the above embodiment, multiple tilt switches are provided, and the multiple tilt switches are arranged on the circuit board at intervals to ensure that when the gyroscope is stationary at any angle, at least one tilt switch is in the disconnected state. Only when the outer shell is rotated to apply a centrifugal force to all the tilt switches, these tilt switches can all be turned on, and then the power supply can transfer electrical energy to the motor to make the motor work. Compared with the gyroscope in the prior art, the gyroscope of the present application only needs to rotate the outer shell to control the operation of the motor, and there is no need to set buttons on the outer shell to control the operation of the motor.

In other words, under the same power supply, the power supply connected to the motor by the current amplification circuit can drive a higher-power motor to work than the power supply connected to the motor without the current amplification circuit, which is conducive to providing greater power for the rotation of the gyroscope. By combining the current amplification circuit and the plurality of tilt switches in accordance with the above-mentioned scheme of the present application, better control of the on and off of the current amplification circuit can be achieved.

DETAILED DESCRIPTION

[0039] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0040] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0042] On the one hand, an embodiment of the present invention provides a gyroscope. In one embodiment, please refer to Figure 1 and Figure 2 The gyroscope includes a housing 1, a motor 2, a circuit board 31 and a tilt switch 33, wherein the housing 1 is the main body of the gyroscope and also provides an installation environment for the motor 2, the circuit board 31 and the tilt switch 33. Figure 1 , the housing 1 has a rotation axis, the rotation axis is Figure 1 The dotted line, the rotation axis, is an axis that every gyroscope has and is a known technology. The center of gravity of the housing 1 is located on the rotation axis, and the housing 1 can rotate around the rotation axis.

[0043] The motor 2 is fixedly mounted on the housing 1, and the output shaft 21 of the motor 2 is coaxially arranged with the rotation axis. In actual production, the output shaft 21 of the motor 2 may not be completely coaxially arranged with the rotation axis, and there is a certain error. As long as the output shaft 21 of the motor 2 is parallel to the rotation axis, and the distance between the output shaft 21 of the motor 2 and the rotation axis 21 does not affect the rotation of the gyroscope, it will be fine.

[0044] One end of the output shaft 21 of the motor 2 away from the motor 2 is located outside the housing 1 and can rotate relative to the housing 1. The housing 1 can rotate around the rotation axis with the end of the output shaft 21 away from the motor 2 as a fulcrum.

[0045] The circuit board 31 is arranged on the shell 1. The circuit board 31 can rotate with the shell 1. The circuit board 31 has a power supply 32 and a current amplifying circuit. The motor 2 and the power supply 32 can be connected through the amplifying circuit, so that the current output by the power supply 32 is amplified by the current amplifying circuit and then transmitted to the motor 2 to control the operation of the motor 2.

[0046] The gyroscope further includes at least two tilt switches 33, which are connected in series to the amplifier circuit and can jointly control the conduction of the amplifier circuit. The at least two tilt switches 33 are arranged on the circuit board 31 at a preset angle interval. The tilt switch 33 has two states: an off state and a pass state. Normally, the tilt switch 33 is in an off state. When the tilt switch 33 is tilted at a certain angle in a certain direction or the tilt switch 33 is subjected to a certain centrifugal force, the tilt switch 33 will be in a pass state due to its internal structural characteristics. It should be noted that the tilt switch 33 belongs to the prior art. For its specific structure and specific principle, please refer to the prior art content, and no further elaboration will be made here.

[0047] By providing a plurality of tilt switches 33 and arranging the plurality of tilt switches 33 at intervals on the circuit board 31, it is ensured that when the gyroscope is stationary at any angle, at least one tilt switch 33 is in an off state, and only when the housing 1 is rotated to apply a centrifugal force to all the tilt switches 33, these tilt switches 33 can all be turned on, and then the power supply 32 can transmit electric energy to the motor 2 to make the motor 2 work. It should be noted that the placement of the tilt switch 33 on the circuit board 31 is based on the condition that it can be in a pass state when subjected to the centrifugal force generated by the rotation of the housing 1, and it cannot be placed upside down, which can be determined according to actual conditions when installing the tilt switch 33.

[0048] Compared with the gyroscope in the prior art, the gyroscope of the present application can control the operation of the motor 2 by rotating the housing 1, without setting buttons on the housing 1 to control the operation of the motor 2. This can avoid setting buttons on the surface of the housing 1 to ensure the integrity of the gyroscope and make the appearance of the gyroscope more beautiful. In addition, the gyroscope needs to be rotated when playing with it. By setting multiple tilt switches 33, the current amplification circuit inside the gyroscope can be controlled to be turned on while the gyroscope is rotated, thereby starting the motor 2 to rotate, so that the gyroscope in the present application can be started when it is rotated like a traditional gyroscope, and it continues to rotate until the power supply 32 is out of power, killing two birds with one stone, and it is more convenient to operate. When closing, you only need to stop the gyroscope from rotating by hand, then the centrifugal force on the tilt switch 33 disappears, the tilt switch 33 is completely disconnected, the amplification circuit is also disconnected, the circuit between the motor 2 and the power supply 32 is disconnected, and the motor stops working.

[0049] By supporting the end of the output shaft 21 of the motor 2 on the rotation plane, the housing 1 can rotate around the output shaft 21 with the end of the output shaft 21 as a fulcrum. When the housing 1 rotates, the motor 2, the circuit board 31 and the tilt switch 33 are driven to rotate. Multiple tilt switches 33 are turned on at the same time, so that the motor 2 runs. The body of the motor 2 is fixedly connected to the housing 1, and can drive the housing 1 to rotate relative to the output shaft 21. When the housing 1 rotates, centrifugal force is continuously provided to the tilt switch 33, so the tilt switch 33 continuously maintains a pass state. That is, the housing 1 can not only rotate around the rotation axis with the output shaft 21 with the end of the output shaft 21 as a fulcrum, but the housing 1 can also rotate relative to the output shaft 21 driven by the motor 2, thereby realizing the continuous rotation of the gyroscope.

[0050] It should be noted that there is a certain friction force between the end of the output shaft 21 and the rotating plane. Assuming that the friction force is represented by f1, when the gyroscope rotates, its housing 1 is subjected to air resistance, which is recorded as f2. In addition, there is a pair of interaction forces inside the motor 2. The pair of forces is generated between the mover and the stator inside the motor 2, and is recorded as the force f3 acting on the output shaft 21 and the upper force f4 acting on the body of the motor 2. When an initial force is applied to the housing 1 to drive the gyroscope to rotate as a whole, although the motor 2 has been started at the beginning, the initial force is relatively large, so the housing 1 and the output shaft 21 rotate in the same direction at the same time with the end of the output shaft 21 as the fulcrum. At this time, f1 is the dynamic friction force, and the directions of f1 and f2 are opposite to the rotation direction of the gyroscope. When f1 and f2 gradually consume the kinetic energy provided by the initial force, if it is an ordinary gyroscope, the rotation speed will gradually slow down until it stops rotating.

[0051] However, in the embodiment of the present application, not only does the housing 1 and the output shaft 21 rotate together, but there is also an action in which the housing 1 is driven by the motor 2 to rotate relative to the output shaft 21. When the output shaft 21 gradually becomes stationary relative to the rotation plane, f3 gradually becomes equal to f1. The preferred situation is that f3 is less than the maximum static friction between the end of the output shaft 21 and the rotation plane, so that the output shaft 21 does not rotate on the rotation plane. However, f4 will drive the housing 1 to rotate relative to the output shaft 21. At this time, only the air resistance f2 prevents the rotation of the housing 1. f4 is greater than f2 to ensure that the housing can continue to rotate. Therefore, the preferred motion state of the gyroscope of the present application is that the output shaft 21 does not rotate, but the motor 2 drives the housing 1 to rotate relative to the rotation plane and the output shaft 21.

[0052] In addition, a current amplifying circuit is also provided on the circuit board 31, and a plurality of tilt switches 33 are connected in series in the current amplifying circuit. When the gyroscope is stationary, at least one tilt switch 33 is in an open circuit state, and the current amplifying circuit is in an open circuit state at this time, and the power supply 32 is not connected to the motor 2. When the gyroscope is rotated to provide centrifugal force to the plurality of tilt switches 33, all the tilt switches 33 are turned on, so that the current amplifying circuit is turned on, and then the power supply 32 is connected to the motor 2. By providing the current amplifying circuit, the current output by the power supply 32 can be amplified to meet the requirements of driving the motor 2, so that the motor 2 can be driven by a smaller power supply 32, saving energy and cost. In other words, in the case of the same power supply 32, the power supply 32 connected to the motor 2 using the current amplifying circuit can drive the motor 2 with a larger power than the power supply 32 connected to the motor 2 without the current amplifying circuit, which is conducive to providing greater power for the rotation of the gyroscope. It should be noted that the rated current allowed to pass through the tilt switch 33 is sometimes smaller than the current required for the motor 2 to work. If the current exceeds the rated current of the tilt switch 33, the tilt switch 33 may be easily damaged. By setting a current amplification circuit, it can be ensured that the current passing through the tilt switch 33 is within its rated current and can still drive the motor 2 to work.

[0053] By combining the current amplifying circuit and the plurality of tilt switches 33 in the manner of the above-mentioned solution of the present application, it is possible to better control the on and off of the current amplifying circuit.

[0054] In a specific embodiment, please refer to Figure 1 and Figure 2 , Figure 2 It is a circuit connection diagram of a specific circuit. The current amplification circuit includes a MOS tube 34, a resistor 36 and several electrical connectors 35. It should be noted that the electrical connector 35 can be a wire or a copper sheet engraved on the circuit board 31, and no further limitation is made here. The MOS tube 34 includes an N-channel MOS tube 34 and a P-channel MOS tube 34. In the embodiment of the present invention, the N-channel MOS tube 34 is used as an example for description. In this embodiment, two tilt switches 33 are provided, namely K1 and K2. The two tilt switches 33 are connected in series. Please refer to Figure 1 The two tilt switches 33 are spaced apart, and the spacing between the two is set to ensure that when the gyroscope is stationary at any angle, at least one of the two tilt switches 33 is disconnected. For example, a preferred setting method is to set the two tilt switches 33 in a straight line, with the rotation axis of the gyroscope as the center and the spacing of 180 degrees.

[0055] Among them, the positive electrode of the power supply 32 is electrically connected to the source electrode S of the MOS tube 34 through the electrical connector 35, one end of the tilt switch 33 connected in series is electrically connected to the gate electrode G of the MOS tube 34 through the electrical connector 35, and the other end is electrically connected to the negative electrode of the power supply 32 through the electrical connector 35. The two ends of the resistor 36 are electrically connected to the positive electrode of the power supply 32 and the gate electrode G of the MOS tube 34 through the electrical connector 35, respectively, and the two electrodes of the motor 2 are electrically connected to the drain electrode D of the MOS tube 34 and the negative electrode of the power supply 32 respectively. Thus, a simple amplification circuit can be formed. When the gyroscope does not rotate, K1 and K2 are in an open circuit state. By utilizing the properties of the MOS tube 34, the entire circuit is in an open state at this time, and the power supply 32 does not supply power to the motor 2.

[0056] When the gyroscope is rotated, both switches K1 and K2 are connected. By utilizing the properties of the MOS tube 34 , the drain D and source S of the MOS tube 34 are connected, and the entire circuit is connected. The power supply 32 supplies power to the motor 2 , and the current amplification effect of the MOS tube 34 can amplify the current output by the power supply 32 .

[0057] It should be noted that the current amplification circuit can also be an amplification circuit that uses a triode for amplification, and multiple tilt switches 33 connected in series can also be set in the amplification circuit that uses a triode for current amplification to control the on and off of the amplification circuit. Of course, there are not only the above two types of current amplification circuits, but also other types of current amplification circuits, which are not described here one by one. It should be clear that no matter what kind of current amplification circuit, it is necessary to use multiple tilt switches 33 connected in series to jointly control the on and off of the circuit, and the multiple tilt switches 33 can only be turned on when the gyroscope rotates, thereby achieving the amplification effect on the current.

[0058] In a specific embodiment, the power source 32 is a rechargeable battery. A charging circuit (not shown in the figure) electrically connected to the power source 32 is provided on the circuit board 31, and a positive charging pin 311 is provided on the charging circuit, or a plurality of positive charging pins 311 are provided in parallel, and a negative charging pin 312 is also provided on the charging circuit, or a plurality of negative charging pins 312 are provided in parallel.

[0059] It should be noted that there is no specific limit on the number of positive charging needles 311 and negative charging needles 312, and the number of the two is also set according to the actual situation. For example, one positive charging needle 311 and one negative charging needle 312 can be set, or one positive charging needle 311 and multiple negative charging needles 312 can be set, or multiple positive charging needles 311 and one negative charging needle 312 can be set. When multiple positive charging needles 311 or negative charging needles 312 are provided, the multiple positive charging needles 311 or multiple negative charging needles 312 are independent of each other and will not affect their respective functions. That is, one of the multiple positive charging needles 311 and one of the multiple negative charging needles 312 can be selected to charge the power supply 32. In the embodiment of the present invention, setting one positive charging needle 311 and one negative charging needle 312 is used as an example for description.

[0060] The length directions of the positive charging needle 311 and the negative charging needle 312 are perpendicular to the board surface of the circuit board 31, and the positive charging needle 311 and the negative charging needle 312 can be connected to an external charging current to charge the power source 32. By setting the power source 32 as a rechargeable battery, and by setting the positive charging needle 311 and the negative charging needle 312, the power source 32 can be charged, so that the power source 32 can be reused, avoiding frequent replacement of the power source 32.

[0061] In a specific embodiment, please refer to Figures 1 to 4 The housing 1 includes an upper housing 11 and a lower housing 12. Both the upper housing 11 and the lower housing 12 are of regular shape. The motor 2, the power supply 32 and the circuit board 31 are all mounted on the lower housing 12. One end of the upper housing 11 has a driving part 111. The driving part 111 is held by hand and a rotational force around the rotation axis is applied to the driving part 111 to rotate the gyroscope. The other end of the upper housing 11 is provided with a receiving cavity 112 which is opened away from the driving part 111. The lower housing 12 can be detachably mounted in the receiving cavity 112.

[0062] It should be noted that a placement groove 121 is provided at one end of the lower housing 12 facing the driving part 111, and a mounting member 13 is fixedly connected to the lower housing 12 in the placement groove 121. The mounting member 13 has a mounting groove 131 extending from one end close to the driving part 111 toward the direction away from the driving part 111. The shape and size of the mounting groove 131 are consistent with the shape and size of the motor 2, so that the motor 2 can be plugged and fitted in the mounting groove 131. The output shaft of the motor 2 is arranged away from the driving part 111, and the output shaft 21 passes through the lower housing 12 in the direction away from the driving part 111.

[0063] One end of the mounting member 13 close to the driving portion 111 is provided with a plurality of notches, through which the peripheral wall of the motor 2 can be exposed, thereby facilitating fingers to contact the peripheral wall of the motor 2 through the notches to remove the motor 2 from the mounting slot 131 .

[0064] It is worth mentioning that the distance between the end of the mounting member 13 close to the driving part 111 and the driving part 111 is greater than the distance between the end of the lower shell 12 close to the driving part 111 and the driving part 111, thereby forming a height difference between the end of the mounting member 13 close to the driving part 111 and the end of the lower shell 12 close to the driving part 111. Preferably, the height difference is set to be equal to the thickness of the circuit board 31, and the outer dimensions of the circuit board 31 are set to match the shape and dimensions of the cross section of the placement groove 121. The circuit board 31 is placed in the placement groove 121 and abuts against the end of the mounting member 13 close to the driving part 111, and the end of the circuit board 31 facing away from the mounting member 13 is flush with the end of the lower shell 12 close to the driving part 111.

[0065] Optionally, the lower shell 12 can be fixedly connected to the peripheral wall of the accommodating cavity 112 by means of interference fit through its outer wall. Alternatively, two spaced through grooves 122 are penetrated on the outer wall of the lower shell 12 near the driving portion 111, and the two through grooves 122 form a notch on the peripheral wall of the lower shell 12, and the two notches can cut the peripheral wall of the lower shell 12 between the two through grooves 122 to form a mounting plate 123. The mounting plate 123 is integrally formed with the lower shell 12 at one end away from the driving portion 111, and the other ends of the mounting plate 123 are detached from the lower shell 12, and a connecting protrusion 124 is convexly provided at one end of the mounting plate 123 facing away from the placement groove 121. When the lower shell 12 is inserted into the accommodating cavity 112, the connecting protrusion 124 abuts against the side wall of the accommodating cavity 112, and the mounting plate 123 is forced to shift toward the mounting member 13. At this time, the mounting plate 123 is deformed and can apply a pressure to the connecting protrusion 124 toward the side wall of the accommodating cavity 112, so that the connecting protrusion 124 is tightly abutted against the side wall of the accommodating cavity 112, thereby achieving a fastened connection between the lower shell 12 and the upper shell 11.

[0066] In a specific embodiment, a plurality of fixing members 40 fixedly connected to the lower shell 12 are provided between the peripheral wall of the lower shell 12 and the peripheral wall of the mounting member 13, and the number of the fixing members 40 is equal to the total number of the positive charging needles 311 and the negative charging needles 312. The position of the fixing member 40 needs to be set so that when the circuit board 31 abuts against the mounting member 13, the arrangement of the fixing member 40 is consistent with the arrangement of the positive charging needles 311 and the negative charging needles 312 on the circuit board 31, that is, the positive charging needles 311 and the negative charging needles 312 can each face one fixing member 40. A through hole 401 is penetrated on the fixing member 40 in a direction perpendicular to the board surface of the circuit board 31, and the end of the through hole 401 away from the driving unit 111 is set through the lower shell 12, and the positive charging needle 311 and the negative charging needle 312 are respectively inserted into the through holes 401 of the corresponding fixing member 40.

[0067] By setting the fixing part 40 and the through hole 401, the positive charging needle 311 and the negative charging needle 312 can be respectively inserted into the corresponding through hole 401, and the positive charging needle 311 and the negative charging needle 312 can both extend out of the lower shell 12 through the through hole 401 away from the end of the driving part 111, so as to facilitate the connection with an external charging device.

[0068] In one embodiment, a positioning member 125 is provided in the lower shell 12, and a positioning groove 313 for plugging and fitting with a partial structure of the positioning member 125 is provided on the circuit board 31, through the plugging and fitting between the partial structure of the positioning member 125 and the positioning groove 313. It should be noted that the position of the positioning member 125 in the lower shell 12 and the position of the positioning groove 313 on the circuit board 31 need to be set according to the cooperation between the positive charging needle 311, the negative charging needle 312 and the fixing member 40. The primary premise for determining the position of the positioning member 125 and the positioning groove 313 is that when the positive charging needle 311 and the negative charging needle 312 are respectively plugged into the corresponding fixing member 40, the positioning groove 313 and the positioning member 125 are respectively set at a certain opposite position between the circuit board 31 and the lower shell 12. In this way, when installing the circuit board 31, it is only necessary to align the positioning groove 313 with the positioning member 125 to ensure that the positive charging needle 311 and the negative charging needle 312 are aligned with the corresponding through hole 401 of the fixing member 40, which facilitates installation.

[0069] In one embodiment, the end of the output shaft 21 away from the motor 2 is arranged in an arc shape, which is consistent with the arrangement of a common gyroscope and is conducive to better rotation of the gyroscope.

[0070] Alternatively, a fulcrum sleeve 50 is sleeved on one end of the output shaft 21 away from the motor 2, and the end of the fulcrum sleeve 50 away from the motor 2 is arranged in an arc shape. It should be noted that the fulcrum sleeve 50 can be made of silicone or rubber material, and has a large friction coefficient, so that the fulcrum sleeve 50 and the rotating plane have a large static friction force, which is conducive to ensuring that when the gyroscope rotates, the output shaft 21 is stationary relative to the rotating plane, and further helps to ensure that the gyroscope can achieve a stable and continuous rotation state.

[0071] In one embodiment, the circuit board 31 is a plate of a centrally symmetrical shape such as a circle or a rectangle. The circuit board 31 is arranged horizontally in the housing 1, that is, the rotation axis is perpendicular to the board surface of the circuit board 31, and the center of gravity (or symmetry center) of the circuit board 31 is located on the rotation axis. Two or more tilt switches 33 connected in series are arranged at intervals around the rotation axis on the circuit board 31, and the two adjacent tilt switches 33 are arranged according to a preset angle, so that when the gyroscope is placed statically, at least one tilt switch 33 is in a disconnected state. For example, if two tilt switches 33 are set, the angle between the two tilt switches 33 can be set to 180°, and if three tilt switches 33 are set, the angle between the two adjacent tilt switches 33 can be set to 60°. Of course, when three or more tilt switches 33 are set, these tilt switches 33 do not need to be arranged at equal intervals, and it is only necessary to ensure that at least one tilt switch 33 can be disconnected when the gyroscope is placed statically at any position.

[0072] On the other hand, an embodiment of the present invention further provides a charging device for charging the aforementioned gyroscope. In one embodiment, please refer to Figures 5 to 7 The charging device includes a support shell 6 for supporting the gyroscope, a charging plate 7 is arranged in the support shell 6, and a positive contact pin 71 and a negative contact pin 72 are arranged on the charging plate 7. The positive contact pin 71 and the negative contact pin 72 can be electrically connected to the positive charging pin 311 and the negative charging pin 312 respectively to form a charging circuit. When the charging plate 7 is connected to the current, the power source 32 can be charged through the charging circuit.

[0073] In a specific embodiment, the support shell 6 includes a bottom shell 61 and a top shell 62, one end of the top shell 62 is provided with an open receiving groove 621, the bottom shell 61 is fixedly connected to the top shell 62, and the bottom shell 61 covers the opening of the receiving groove 621 to close the receiving groove 621.

[0074] The end of the top shell 62 facing away from the bottom shell 61 is recessed to form an abutment groove 622, and the end of the housing 1 close to the output shaft 21 can be installed and adapted in the abutment groove 622. The top shell 62 is also provided with a clearance groove 623 connected to the abutment groove 622 at a position on the bottom wall of the abutment groove 622 facing the output shaft 21, and the output shaft 21 can be inserted into the clearance groove 623.

[0075] The positive contact needle 71 and the negative contact needle 72 are both inserted into the top shell 62 and are located at the position of the abutment groove 622 on the top shell 62. One end of the positive contact needle 71 and the negative contact needle 72 protrude from the bottom of the abutment groove 622. The positions of the positive contact needle 71 and the negative contact needle 72 protruding from the bottom of the abutment groove 622 correspond to the positions where the positive charging needle 311 and the negative charging needle 312 are inserted out of the lower shell 12, respectively, so that when the gyroscope is installed in the abutment groove 622, the positive contact needle 71 can abut against the positive charging needle 311, and the negative contact needle 72 can abut against the negative charging needle 312.

[0076] In a specific embodiment, please combine Figure 4 A plurality of first mounting parts 80 fixedly connected to the lower shell 12 are also arranged between the outer wall of the mounting member 13 and the inner wall of the lower shell 12. The first mounting part 80 is hollow, and a first magnet 81 is arranged at one end of the first mounting part 80 away from the driving part 111. A plurality of second mounting parts 90 are arranged at the position of the first magnet 81 at one end of the top shell 62 facing away from the abutment groove 622. The second mounting part 90 is hollow, and a second magnet 91 is arranged at one end of the second mounting part 90 close to the abutment groove 622. When the gyroscope is placed in the abutment groove 622, the plurality of first magnets 81 can be arranged one by one with the plurality of second magnets 91, respectively. Through the mutual attraction between the first magnet 81 and the second magnet 91, the position of the gyroscope in the abutment groove 622 is relatively stable.

[0077] For a specific setting method, please refer to Figure 1 and Figure 6 , two first magnets 81 and second magnets 91 are set. When setting, one of the first magnets 81 and one of the second magnets 91 is set to be able to attract each other, and the other second magnet 91 is set to repel each other, and the other first magnet 81 is set to be opposite. In this way, the two first magnets 81 can attract each other with the corresponding second magnets 91, and repel each other with the non-corresponding ones. Such a setting allows the lower shell 12 and the top shell 62 to be directional connected in a way that the two first magnets 81 and the two second magnets 91 attract each other.

[0078] In this way, by setting the positions of the positive contact pin 71, the positive charging pin 311, the negative contact pin 72 and the negative charging pin 312, accurate alignment between the contact pins and the charging pins can be achieved. Specifically, when the two first magnets 81 and the two second magnets 91 correspond to each other in a mutually attractive manner, the positive contact pin 71 can just face the positive charging pin 311, and the negative contact pin 72 can just face the negative charging pin 312, thereby achieving rapid alignment between the positive contact pin 71 and the positive charging pin 311, and rapid alignment between the negative contact pin 72 and the negative charging pin 312.
