Therefore, these and other directional terms should not be construed as limiting terms.
The first embodiment is as follows:
referring to fig. 3-10, there are shown schematic views of a toy drive system according to one embodiment of the present invention.
As shown in fig. 6, the toy driving system 10 includes a power unit 1, a first output mechanism 2, a second output mechanism 3, a clutch transmission mechanism 4 and a one-way transmission mechanism 5, wherein the one-way transmission mechanism 5 is connected between the first output mechanism 2 and the second output mechanism 3, the one-way transmission mechanism 5 transmits power from the first output mechanism 2 to the second output mechanism 3 in a one-way manner, and the clutch transmission mechanism 4 is connected between the power unit 1 and the second output mechanism 2;
when the power unit 1 rotates in a first direction, the power unit 1 drives the first output mechanism 2 to rotate, the power unit 1 drives the second output mechanism 3 to rotate through the clutch transmission mechanism 4, the one-way transmission mechanism 5 does not transmit power, and the first output mechanism 2 and the second output mechanism 3 rotate in opposite directions;
when the power unit 1 rotates in the second direction, the first output mechanism 2 is driven to rotate, the clutch transmission mechanism 4 is disengaged from the second output mechanism 3, the first output mechanism 2 transmits power to the second output mechanism 3 through the one-way transmission mechanism 5, and the first output mechanism 2 and the second output mechanism 3 rotate in the same direction.
Specifically, the power unit 1 provides a power source for the toy driving system 10, and the power of the power unit 1 is transmitted to the first output mechanism 2 and the second output mechanism 3, and then transmitted to the external toy moving part through the first output mechanism 2 and the second output mechanism 3. For example: the first output mechanism 2 and the second output mechanism 3 are each coupled to a wheel of the toy vehicle to enable the toy vehicle to advance and turn.
Alternatively, the first output mechanism 2 and the second output mechanism 3 may be connected to other toy moving elements.
The first output mechanism 2 is directly connected to the power unit 1, and the power of the power unit 1 can be directly transmitted to the first output mechanism 2.
The second output mechanism 3 is connected with the power unit 1 through a clutch transmission mechanism 4, the first output mechanism 2 is connected with the second output mechanism 3 through a one-way transmission mechanism 5, and the one-way transmission mechanism 5 transmits power from the first output mechanism 2 to the second output mechanism 3 in a one-way mode.
Therefore, the power of the second output mechanism 3 has two transmission paths:
a first transmission path: the power unit 1, the clutch transmission mechanism 4 and the second output mechanism 3;
a second transmission path: the power unit 1, the first output mechanism 2, the one-way transmission mechanism 5 and the second output mechanism 3.
In the first transmission path, the one-way transmission mechanism 5 does not transmit; in the second transmission path, the clutch transmission 4 is disengaged from the second output 3.
In this embodiment, when the power unit 1 rotates in the first direction, the second output mechanism 3 executes the first transmission path, the first output mechanism 2 and the second output mechanism 3 rotate in opposite directions, and when the first output mechanism 2 and the second output mechanism 3 are connected to the wheels of the toy vehicle, the steering motion of the toy vehicle can be realized;
when the power unit 1 rotates in the second direction, the second output mechanism 3 executes the second transmission path, the first output mechanism 2 and the second output mechanism 3 rotate in the same direction, and when the first output mechanism 2 and the second output mechanism 3 are installed on wheels of a toy car, the forward or backward movement of the toy car can be realized.
In the present embodiment, the first output mechanism 2 and the second output mechanism 3 are driven simultaneously by one power unit 1, and the first output mechanism 2 and the second output mechanism 3 rotate in the same direction or in opposite directions by switching the clutch transmission mechanism 4 and the one-way transmission mechanism 5. The structure is simplified, and the cost is reduced.
Further, as shown in fig. 3, the power unit 1 includes an electric motor 11, a driving gear 12 and a first gear 13, the electric motor 11 drives the driving gear 12 to rotate, the driving gear 12 is meshed with the first gear 13, and the first gear 13 directly drives the first output mechanism 2 and the clutch transmission mechanism 4.
Specifically, the output shaft of the motor 11 is coaxially connected to a drive gear 12, and the axis of the drive gear 12 and the axis of the first gear 13 are perpendicular to each other and are both arranged in the horizontal direction. The first gear 13 is used to change the transmission direction of the drive gear 12.
Alternatively, the power unit 1 may also include other transmission gears or transmission members to function as a power output.
Further, as shown in fig. 4, the clutch transmission mechanism 4 includes a second gear 41, and the second gear 41 is engaged with the first gear 13 and directly transmitted with the second output mechanism 3;
when the power unit 1 rotates in the first direction, the first gear 13 drives the second gear 41 to rotate, and the second gear 41 drives the second output mechanism 3 to rotate;
when the power unit 1 rotates in the second direction, the first gear 13 drives the second gear 41 to rotate, the second output mechanism 3 drives the second gear 41 in the reverse direction, and the second gear 41 is disengaged from the second output mechanism 3.
Specifically, the drive gear 12 meshes with the first gear 13, the first gear 13 meshes with the second gear 41, and the second gear 41 meshes with the fourth gear 31 of the second output mechanism 3.
The axis of the second gear 41 is arranged in the horizontal direction and is parallel to the axis of the first gear 13.
The first transmission path of the second output mechanism 3 is: motor 11-drive gear 12-first gear 13-second gear 41-fourth gear 31.
The second gear 41 is always engaged with the first gear 13, and the second gear 41 is switched between engagement and disengagement with the second output mechanism 3.
When the power unit 1 rotates in the first direction, the second gear 41 meshes with the fourth gear 31 between the second output mechanism 3, and the transmission of the first transmission path is realized.
When the power unit 1 rotates in the second direction, the first gear 13 still drives the second gear 41 to rotate, and the fourth gear 31 drives the second gear 41 reversely, so that the fourth gear 31 is pushed upwards to be disengaged from the fourth gear 31, and the first transmission path is cut off.
At this time, since the one-way transmission mechanism 5 functions, the power of the first output mechanism 2 is transmitted to the second output mechanism 3, and the transmission of the second transmission path is realized.
Alternatively, the clutch transmission 4 may also be composed of another clutch transmission, as long as the switching between the connection and disconnection of the transmission path to and from the second output 3 can be achieved.
Further, as shown in fig. 6, the device further includes a first mounting shaft 14, a second mounting shaft 42, a first support 6 and a second support 7, wherein the first gear 13 is mounted on the first mounting shaft 14, the second gear 41 is mounted on the second mounting shaft 42, and two ends of the first mounting shaft 14 and the second mounting shaft 42 are respectively connected with the first support 6 and the second support 7;
the first support member 6 and the second support member 7 are both provided with a circular positioning hole 15 and a long positioning groove 43, the positioning hole 15 is connected with the first mounting shaft 14, and the positioning groove 43 is connected with the second mounting shaft 42.
Specifically, as shown in fig. 4, the first support member 6 and the second support member 7 are located on the left and right sides, and function to support and mount the power unit 1 and other transmission members.
The first supporting member 6 and the second supporting member 7 are both plate structures, and as shown in fig. 6-7, the first supporting member 6 and the second supporting member 7 are both provided with a circular positioning hole 15 and a long positioning groove 43.
The positioning hole 15 is used for installing the first installation shaft 14, the first installation shaft 14 is fixedly connected with the two positioning holes 15, and the first gear 13 rotates around the first installation shaft 14.
The positioning slot 43 is used for mounting the second mounting shaft 42, the length direction of the positioning slot 43 is arranged approximately along the up-down direction, when the second output mechanism 3 reversely drives the second gear 41, the second gear 41 is pushed to be disengaged upwards, the second gear 41 and the second mounting shaft 42 move upwards together, and the positioning slot 43 provides a space for the upward movement of the second mounting shaft 42.
Preferably, the second gear 41 is made of plastic and is light in weight. When the second gear 41 is pushed above the positioning groove 43, the end of the second mounting shaft 42 remains above the positioning groove 43 even if the motor 11 stops rotating.
Preferably, the positioning groove 43 is filled with grease, which increases the adhesion between the second mounting shaft 42 and the positioning groove 43, so that the second mounting shaft 42 can be held above the positioning groove 43. Only when the power unit 1 is rotated in the first direction, the first gear 13 can bring the second gear 41 back under the positioning slot 43 to mesh with the fourth gear 31.
Further, as shown in fig. 8, the first mounting shaft 14 and the second mounting shaft 42 are connected by the link 8 such that the first gear 13 and the second gear 41 remain meshed.
Specifically, two round holes 81 are formed in the connecting rod 8, and the connecting rod 8 is used for maintaining the distance between the first mounting shaft 14 and the second mounting shaft 42. When the second mounting shaft 42 moves up and down, one end of the connecting rod 8 is driven to move up and down, so that one end of the connecting rod 8 rotates around the other end sleeved on the first mounting shaft 14.
Preferably, the positioning groove 43 is shaped as an arc groove, and the center of the arc groove coincides with the center of the positioning hole 15.
The positioning groove 43 and the second mounting shaft 42 should have a certain clearance for reducing sliding friction; however, since the backlash may cause the second gear 41 to jump in tooth, the second gear 41 and the first gear 13 may not be in a stable meshing relationship, and the second gear 41 may be disengaged from the first gear 13, and the second gear 41 may not return to a state of meshing with the fourth gear 31, or may be stuck to cause gear damage.
Therefore, in order to maintain the first gear 13 and the second gear 41 in a stable meshing state, a positional relationship is provided in which the one link 8 is engaged with the first mounting shaft 14 and the second mounting shaft 42 to be maintained stably.
Further, as shown in fig. 6, the first output mechanism 2 includes a third gear 21 and a first output shaft 22, the third gear 21 is coaxially connected with the first output shaft 22, the third gear 21 is meshed with the first gear 13, and the third gear 21 is connected with the second output mechanism 3 through the one-way transmission mechanism 5.
The second output mechanism 3 includes a fourth gear 31 and a second output shaft 32, the fourth gear 31 is coaxially connected with the second output shaft 32, and the second gear 41 is meshed with the fourth gear 31.
In the present embodiment, as shown in fig. 5, the first gear 13 is directly engaged with the third gear 21, and the first gear 13 is not directly engaged with the fourth gear 31, but indirectly connected with the fourth gear 31 through the second gear 41. In fig. 10, the fourth gear 31 is not actually meshed with the first gear 13 in a side view.
Specifically, the positioning device further comprises a positioning shaft 23, and the third gear 21, the fourth gear 31, the first output shaft 22, the second output shaft 32 and the one-way transmission mechanism 5 are all arranged on the positioning shaft 23 coaxially, so that the connection stability between the components can be improved. One end of the positioning shaft 23 is inserted into the first output shaft 22, and the other end is inserted into the second output shaft 32.
Fig. 6 is connected from left to right, and the first output shaft 22, the third gear 21, the one-way transmission mechanism 5, the fourth gear 31 and the second output shaft 32 are connected in sequence.
Alternatively, the first output 2 and the second output 3 can also consist of other transmission elements.
Further, as shown in fig. 6, the first supporting member 6 is further provided with a first shaft hole 61, and the second supporting member 7 is provided with a second shaft hole 71. The first shaft hole 61 is used for the first output shaft 22 of the first output mechanism 2 to pass through, and the second shaft hole 71 is used for the second output shaft 32 of the second output mechanism 3 to pass through.
Further, as shown in fig. 9-10, the one-way transmission mechanism 5 includes a ratchet wheel, the ratchet wheel includes a fixing portion 51 and a pawl portion 52, the fixing portion 51 is fixedly connected with the third gear 21, and the pawl portion 42 is engaged with the ratchet teeth 311 on the inner ring of the fourth gear 31.
Specifically, the fixing portion 51 is substantially a quadrangular cylinder, a quadrangular fixing groove 211 is formed in one surface of the third gear 21 facing the ratchet wheel, and the fixing portion 51 is inserted into the fixing groove 211, so that the third gear 21 always drives the ratchet wheel to rotate.
The pawl portion 52 includes two pawls, and the inner ring of the side of the fourth gear 31 facing the ratchet wheel is formed with ratchet teeth 311, and the pawl portion 52 is engaged with the ratchet teeth 311. The engagement of the pawl part 52 with the ratchet 311 enables the fourth gear 31 to rotate when the third gear 21 rotates in one direction; when rotating in the opposite direction, the fourth gear 31 is not driven to rotate.
When the fourth gear 31 is driven by the second gear 41, the pawl portion 52 and the ratchet teeth 311 are not transmitted, and the power of the fourth gear 31 is not transmitted to the third gear 21.
Further, as shown in fig. 6, elastic clutch mechanisms 9 are respectively arranged between the first output shaft 22 and the third gear 21, and between the second output shaft 32 and the fourth gear 31;
the elastic clutch mechanism 9 comprises an elastic sheet 91 and a spline 92, the elastic sheet 91 is sleeved at the inner ends of the first output shaft 22 and the second output shaft 32, the spline 92 is formed at the inner rings of the third gear 21 and the fourth gear 31, and the elastic sheet 91 is in transmission fit with the spline 92 or is disengaged in an overload mode.
Specifically, a spline 92 is formed on the third gear 21 and the fourth gear 31 on the side facing the spring piece 91, and the spring piece 91 is inserted into the spline 92. The splines 92 are formed on the outer side surfaces of the third gear 21 and the fourth gear 31, and the inner side surfaces of the third gear 21 and the fourth gear 31 are used for being matched with the ratchet wheel.
When the motor 11 operates, the spline 92 is in transmission fit with the elastic sheet 91 to transmit power to the first output shaft 22 and the second output shaft 32 respectively.
When the motor 11 stops operating, the third gear 21 and the fourth gear 31 also stop rotating. At this time, if a person forcibly rotates the first and second output shafts 22 and 32 from the outside, the gears inside may be damaged.
Therefore, by the arrangement of the elastic clutch mechanism 9, when the first output shaft 22 and the second output shaft 32 are forcibly rotated from the outside, the elastic pieces 91 are disengaged from the splines 92, preventing damage to the internal transmission members.
For example: when toy drive system 10 is used with a toy vehicle, a child forcibly twists the wheels, causing first output shaft 22 and second output shaft 32 to rotate. At this time, the spring pieces 91 are disengaged from the splines 92, and damage to internal gears and the like is prevented.
Preferably, the second gear 41 is smaller than the diameter of the first gear 13, the first gear 13 is smaller than the diameters of the third gear 21 and the fourth gear 31, and the diameters of the third gear 21 and the fourth gear 31 are equal. Because the rotating speed of the motor is high and the torque is small, the torque generated by the motor is reduced and increased through the gear set, so that the torque is suitable for turning and running of the toy car.
As illustrated below, the operation of the toy drive system 10 of the first embodiment is as follows:
1. the first output mechanism 2 and the second output mechanism 3 rotate reversely:
as shown in fig. 4, when the driving gear 12 is driven by the motor 11 to rotate clockwise, the first gear 13 rotates to the outside of the paper surface, the first gear 13 drives the third gear 21 to rotate to the inside of the paper surface, and the first output shaft 22 also rotates to the inside of the paper surface;
the first gear 13 rotates the second gear 41 also inward in the drawing, and the second gear 41 meshes with the fourth gear 31 to rotate the fourth gear 31 outward in the drawing, so that the second output shaft 32 also rotates outward in the drawing, and the first output shaft 22 and the second output shaft 32 are steered in different directions.
At this time, the one-way transmission mechanism 5 does not transmit power.
2. The first output mechanism 2 and the second output mechanism 3 rotate in the same direction:
when the motor 11 drives the driving gear 12 to rotate counterclockwise, the first gear rotates in the direction opposite to the arrow direction in fig. 4, that is, the first gear 13 rotates toward the inside of the paper, the first gear 13 drives the third gear 21 to rotate toward the outside of the paper, and at this time, the first output shaft 22 also rotates toward the outside of the paper;
the first gear 13 rotates the second gear 41 to the outside of the paper. Meanwhile, the third gear 21 drives the fourth gear 31 to rotate in the same direction through the one-way transmission mechanism 5, so that the second output shaft 32 also rotates towards the inner side of the paper, and at the moment, the first output shaft 22 and the second output shaft 32 rotate in the same direction.
As shown in fig. 10, the fourth gear 31 applies a clockwise force to the second gear 41, the first gear 13 applies a counterclockwise force to the second gear 41, and the two opposite forces cause the second gear 41 to receive an F resultant force and to be pushed in the F direction, so that tooth skipping of the second gear 41 is realized, and the fourth gear 31 is disengaged from the second gear 41.
The rotation directions of the components in the first embodiment are only examples, and the rotation directions may be changed after the connection positions of the components are slightly changed or after a certain component is replaced.
By implementing the first embodiment, the toy driving system can control the rotation of the two output shafts simultaneously only by one motor 11, and can realize the switching between the rotation in the same direction and the rotation in the opposite direction. And a steering mechanism does not need to be arranged independently, or a group of power sources and transmission mechanisms do not need to be added. The structure is simplified, the cost is reduced, the structure is compact, and the occupied space is small.
Example two:
as shown in fig. 1-2, the toy vehicle includes a body 20, a first drive wheel 30, a second drive wheel 40, and a toy drive system 10, with a first output mechanism 2 coupled to first drive wheel 30 and a second output mechanism 3 coupled to second drive wheel 40.
Wherein the first drive wheel 30 and the second drive wheel 40 are located at the rear of the vehicle, and the toy vehicle further comprises a front right wheel 50 and a front left wheel 60 located at the front of the vehicle.
When the first output mechanism 2 and the second output mechanism 3 rotate in the same direction, the first driving wheel 30 and the second driving wheel 40 rotate in the same direction, and the forward motion of the toy car can be realized.
When the first output mechanism 2 and the second output mechanism 3 rotate reversely, the first driving wheel 30 and the second driving wheel 40 rotate reversely, and the turning action of the toy car can be realized.
Optionally, when the first output mechanism 2 and the second output mechanism 3 rotate in the same direction, the toy vehicle can also move backwards, and the turning of the toy vehicle can be left-turning or right-turning.
Alternatively, toy drive system 10 is not limited to use on toy vehicles, but may be a walking robot having at least two wheels, or a walking animal toy, or other toy capable of advancing, backing, and steering.
The foregoing is considered as illustrative only of the principles and preferred embodiments of the invention. It should be noted that, for those skilled in the art, several other modifications can be made on the basis of the principle of the present invention, and the protection scope of the present invention should be regarded.
