Description
Technical Field
[0001] The present invention belongs to the technical field of mechanical transmission, and in particular relates to an auxiliary machine for assisting a motor in outputting power and a bidirectional power recovery method thereof. Background Art
[0002] In the field of motor auxiliary devices, there is no mature solution to assist motor output work through bidirectional swing. The bidirectional swing device is usually composed of an auxiliary machine body, on which an output shaft is installed. The output shaft is divided into a swing mounting end and an output connection end. The swing mounting end is connected to a swing rod, and the output connection end is connected to a power interface to provide power for the machine. The swing rod is connected to a connecting rod, which is connected to an eccentric wheel, which is installed on the motor shaft. When working, the motor controls the shaft to rotate, drives the eccentric wheel to rotate, and then moves the connecting rod, causing the swing rod to swing, and finally drives the output shaft of the auxiliary machine body to rotate. This bidirectional swing device uses the lever effect to design the swing rod fulcrum position so that the power arm is larger than the resistance arm, and the torque can be further amplified according to the lever principle. However, this technology has many problems to be solved. For example, in the forward swing stage, although the output shaft on the auxiliary machine body can be driven by a lever to achieve torque amplification, in the reverse swing stage, how to effectively control the output shaft on the auxiliary machine body from rotating becomes a major problem. If the output shaft rotates during the reverse swing, the equipment will not be able to operate normally. When solving the above problems, there is still a key problem that has not been solved, how to reasonably utilize the force in the reverse swing stage to achieve power recovery and utilization. If these problems can be effectively solved, the bidirectional swing device can be applied to meet the urgent needs of modern industry for efficient and energy-saving transmission devices. Summary of the invention
[0003] The purpose of the present invention is to provide a method for converting the rotational motion of a motor into the swing of a swing arm, amplifying the torque through the lever principle, and adding a double check wheel system to realize intelligent switching of power channels, so as to solve the problems existing in the prior art. To achieve the above purpose, the specific technical scheme of the present invention is: a motor output auxiliary machine, including a power conversion module and a transmission execution system, the power conversion module is composed of an eccentric wheel and a connecting rod to form a crank slider mechanism, which is used to receive the power provided by the motor shaft, and convert the rotational motion of the motor into the swing of the swing arm, thereby assisting the motor; the swing arm includes a power arm and a resistance arm, the power arm of the swing arm is larger than the resistance arm, the power arm is hinged to the connecting rod through a pin, and the resistance arm integrates a first check wheel and a main gear.
[0004] Preferably, the transmission execution system includes: an output shaft, which is connected to the first check wheel and is also provided with a fourth driven wheel; a first mating shaft, which is equipped with the second driven wheel and the second check wheel, and the second check wheel is equipped with the first driven wheel; a second mating shaft, which carries the third driven wheel; the main gear is meshed with the first driven wheel on the first mating shaft, the second driven wheel is meshed with the third driven wheel, and the third driven wheel is meshed with the fourth driven wheel.
[0005] Preferably, the locking directions of the first check wheel and the second check wheel are opposite; when the swing arm swings forward, the first check wheel is locked and the second check wheel is overtaken; when the swing arm swings reversely, the second check wheel is locked and the first check wheel is overtaken.
[0006] In this technology, in order to achieve the effect of small input force and large output force, the gear transmission part is optimized, the tooth ratio of the main gear and the first driven gear is increased, multiple sets of gears are connected in series, and a planetary gear mechanism is designed between the output shaft and the load. The characteristics of the planetary gear mechanism are used to further amplify the torque.
[0007] In this technology, in order to achieve the effect of small input force and large output force, the length and width of the swing arm are optimized, the ratio of the power arm to the resistance arm is increased, and the torque is further amplified.
[0008] Preferably, the output shaft comprises a gear connecting end and an output connecting end, the gear connecting end of the output shaft is connected to the first check wheel, and the output connecting end of the output shaft is connected to the machine power interface to provide power to the machine.
[0009] A bidirectional power recovery method for a motor output auxiliary machine, characterized by comprising the following steps: Forward drive stage: the motor drives the eccentric wheel to push the swing rod to swing forward, and the first check wheel is locked; the power is directly output through the swing rod → first check wheel → output shaft; the gear system reverses the transmission to force the first matching shaft to synchronize with the output shaft; Reverse recovery stage: the swing arm swings in the reverse direction to trigger the locking of the second check wheel; the power is output for the second time through the main gear → gear transmission chain → output shaft.
[0010] In this technology, in the forward swing stage, when the swing lever swings, the first check wheel enters a locked state, establishing a direct mechanical coupling between the swing lever and the output shaft, and realizing efficient power transmission. At this time, the main gear drives the first driven wheel to produce an idling effect, and the second check wheel is in an overrunning state, blocking the power transmission between the first driven wheel and the first mating shaft; synchronously, the output shaft rotates to drive the fourth driven wheel, the third driven wheel, and the second driven wheel, forcing the first mating shaft to maintain angular velocity synchronization with the output shaft.
[0011] In this technology, during the reverse swing stage, the first check wheel switches to a free state, releasing the rigid connection between the swing lever and the output shaft. The second check wheel enters a locked state, activating the gear transmission chain, i.e., the main gear, the first driven wheel, the first mating shaft, the second driven wheel, the third driven wheel, the fourth driven wheel to the output shaft, to achieve effective power transmission.
[0012] Core structural system: The power conversion module consists of an eccentric wheel and a connecting rod to form a crank slider mechanism, which converts the rotation of the motor into the swing of the swing arm. The swing arm fulcrum position is designed so that the power arm is larger than the resistance arm, so the torque can be amplified through the lever principle. The swing arm is equipped with a two-way drive interface, namely the power arm and the resistance arm. The power arm is hinged to the connecting rod through a pin, and the resistance arm integrates the first check wheel and the main gear. Through the carefully designed gear meshing matrix, the main transmission chain and the reverse constraint chain are constructed to ensure efficient and stable transmission of power.
[0013] Beneficial effects: The present invention improves power utilization through a double check wheel system, significantly reduces energy consumption, and improves the operating efficiency of the equipment. In the first half of the swing, a direct drive mode is used to achieve efficient power transmission; in the second half of the swing, a gear transmission mode is used to complete power recovery, greatly improving power utilization. A dynamic coupling mechanism is used to achieve autonomous selection of the drive path through intelligent switching of the first check wheel and the second check wheel to adapt to different movement requirements. Through the output of two sets of power paths, the continuous and stable operation of the device is guaranteed, solving the problems existing in the background technology.

[0019] The embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings. The implementation methods of the present disclosure are described below through specific specific examples. Those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples; however, those skilled in the art will understand that the aspects described can be practiced without these specific details; the embodiments of the present disclosure provide a device for assisting motor output, which will be further described below in conjunction with the accompanying drawings.
[0020] See also Figure 1-3 It can be seen that a preferred embodiment of the present invention is a motor output auxiliary machine, including an auxiliary machine body 1, on which an output shaft 18, a first mating shaft 4 and a second mating shaft 3 are installed. The output shaft 18 includes a gear connecting end 17 and an output connecting end 2. The gear connecting end 17 of the output shaft 18 is connected to the swing rod 5 through a first check wheel 14. The output connecting end 2 of the output shaft 18 is connected to the power interface of the machine to provide power to the machine. The swing rod 5 includes a power arm 12 and a resistance arm 13. The resistance arm 13 is connected to the first check wheel 14. A main gear 19 is installed on the resistance arm 13. The power arm 12 of the swing rod 5 is connected to the connecting rod 7. The connecting rod 7 is connected to the eccentric wheel 8. The eccentric wheel 8 is connected to the rotating shaft 10 of the motor 11. The rotating shaft 10 is controlled by the motor 11 to work, so that the eccentric wheel 8 rotates, thereby driving the connecting rod 7 to move, so that the swing rod 5 performs bidirectional swinging.
[0021] Furthermore, the connecting rod 7 and the eccentric wheel 8 are connected via a first bearing 9 to reduce friction during operation and extend service life, and the connecting rod 7 and the swing rod 5 are connected via a second bearing 6 to reduce friction during operation and extend service life.
[0022] Furthermore, a fourth driven wheel 15 is mounted on the gear connecting end 17 of the output shaft 18, a second check wheel 20 and a second driven wheel 22 are mounted on the first mating shaft 4, a first driven wheel 21 is mounted on the second check wheel 20, a third driven wheel 16 is mounted on the second mating shaft 3, the main gear 19 is meshed with the first driven wheel 21 on the first mating shaft 4, the second driven wheel 22 is meshed with the third driven wheel 16, and the third driven wheel 16 is meshed with the fourth driven wheel 15.
[0023] Furthermore, when the swing arm 5 swings toward side A, the swing arm 5 drives the main gear 19 to rotate half a circle. At this time, the first check wheel 14 is locked so that the swing arm 5 can drive the output shaft 18 to rotate. At the same time, the main gear 19 drives the first driven wheel 21 to rotate. The rotation of the first driven wheel 21 cooperates with the second check wheel 20 so that the rotation of the first driven wheel 21 will not drive the first matching shaft 4 to rotate. After the output shaft 18 rotates, it drives the fourth driven wheel 15 to rotate. The fourth driven wheel 15 drives the third driven wheel 16 to rotate. The third driven wheel 16 drives the second driven wheel 22 to rotate, so that the first matching shaft 4 and the output shaft 18 rotate in the same direction, thereby completing the unidirectional output rotation.
[0024] Furthermore, the focus of the swing arm 5 is on how to utilize the swinging force. Specifically, when the swing arm 5 swings to the other side B, the swing arm 5 drives the main gear 19 to return to the center and continue to rotate half a circle. At this time, the first check wheel 14 is not locked, so that the swing arm 5 cannot drive the output shaft 18 to rotate. At the same time, the main gear 19 drives the first driven wheel 21 to rotate, and the first driven wheel 21 rotates to cooperate with the second check wheel 20 to complete the locking, so that the first driven wheel 21 rotates to drive the first matching shaft 4 to rotate, and the first matching shaft 4 rotates and drives the second driven wheel 22 to rotate, and the second driven wheel 22 drives the third driven wheel 16 to rotate, and the third driven wheel 16 drives the fourth driven wheel 15 to rotate, and the fourth driven wheel 15 rotates to drive the output shaft 18 to rotate and rotate in the same direction as the first matching shaft 4, thereby completing the utilization of the swinging force.
[0025] Furthermore, the entire actions toward A and toward B are to make the output shaft 18 rotate continuously in one direction.
[0026] Furthermore, the check wheel uses a ratchet structure, and can also be replaced by a one-way bearing structure or an overrunning clutch structure; the fulcrum position of the swing rod 5 is designed so that the power arm 12 is larger than the resistance arm 13, and the torque can be further amplified through the lever principle. If the length ratio on both sides of the fulcrum of the swing rod 5 is 3:1, the torque amplification is approximately equal to 3 times, realizing the key design of "small input and large output".
[0027] In summary, the above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present disclosure should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
