Description

Hopping robot bouncing mechanism based on energy meshing conversion
Technical Field
The invention belongs to the field of robots, relates to a bouncing mechanism, and particularly relates to a bouncing mechanism of a hopping robot based on energy meshing conversion.
Background
The jumping robot is an important component of intelligent robot development, has the advantages of strong maneuvering performance, high moving speed, strong obstacle crossing capability and the like, and has good application prospect in fields unsuitable for human operation, such as rescue and relief work, military investigation, forest protection, foreign exploration, anti-terrorism explosion prevention and the like.
The jumping mechanism is the most basic element for determining the performance of the jumping robot, and is mainly divided into two types according to different construction methods. One is a bionic bouncing mechanism, i.e. elicitation and imitation from the jumping action of natural creatures, such as mechanical crickets, mechanical fleas, etc. As is known, each motion function of an organism is realized under the action of multiple factors such as bones, muscles, nervous systems and the like, and the energy conversion efficiency is as high as 100%, while most of the existing bionic bouncing mechanisms are rigid structures and have great difference with the physiological characteristics of the organism, so that the energy conversion efficiency and the explosive force of the existing bionic bouncing mechanisms cannot be comparable to the real muscle system of the organism. The other is an elastic bouncing mechanism, i.e. a bouncing mechanism which generates an elastic force by a simple mechanism (such as a spring). At present, in the existing elastic bouncing mechanism, when the linear spring is not completely bounced, that is, the elastic potential energy is not completely converted into kinetic energy, the mechanism starts to leave the ground in advance, so that the energy conversion efficiency is low. In addition, the maximum output torque of the motor depends on the elastic force of the spring when the spring is compressed to the maximum, so that the output torque of the motor does not need to reach the maximum value, namely, the utilization rate of the motor is low. As described above, one of the common problems of the two types of bouncing mechanisms is low energy conversion efficiency. Therefore, the jumping mechanism has the advantages of improving the energy conversion efficiency of the jumping mechanism, realizing efficient storage and release of energy and necessary buffering action, having important theoretical and practical significance for improving jumping performance and relieving landing impact, and being one of key technologies which need to be solved urgently in the field of robots.

The driving motor 21 drives the driving noncircular gears 231 of the two energy conversion bouncing units at the two sides of the main body support 1 to rotate through the transmission unit, the driving noncircular gears 231 rotate to drive the driven noncircular gears 232 to rotate, the circular gears 233 rotate along with the driven noncircular gears 232 and downwards rotate on a straight line segment of the racks 234, the upper end of the elastic component and the main body support 1 downwards move along with the circular gears, and the springs 2351 are stretched to store elastic energy.
Specifically, when the circular gear 233 rotates on the rack 234, the driven non-circular gear 232 is driven to move up and down, the driven non-circular gear 232 drives the driving non-circular gear 231 to move up and down, and the secondary gear shaft 224 moves up and down along with the driving non-circular gear 231 and drives the steering wheel 36 and the main body bracket 1 to move up and down.

When the spring 2351 releases energy, the articulation of the second link 2353 and the fourth link 2355, and the articulation of the first link 2352 and the third link 2354, respectively, move in a direction therebetween, the first link 2352 and the second link 2353 move upward, and the steering wheel 36 moves upward accordingly.
As shown in fig. 6a, the gear pitch curve of the driving non-circular gear 231 is formed by sequentially connecting three curves of the driving speed increasing section 231a, the driving constant speed section 231b and the driving speed reducing section 231c end to end in a smooth manner in a clockwise direction. In the clockwise direction, the active speed increasing section 231a is a tapered curve, the active constant velocity section 231b is an equal radius curve, and the active speed reducing section 231c is a diverging curve. The gradually-reduced curve means that the distance from each point on the curve to the rotation center A of the gear is gradually reduced along the clockwise direction. The equal radius curve means that the distances from each point on the curve to the rotation center of the gear are equal. The gradually expanding curve means that the distance from each point on the curve to the rotation center of the gear gradually increases along the clockwise direction.
As shown in fig. 6b, the gear pitch curve of the driven non-circular gear 232 is formed by sequentially connecting three curves of a driven deceleration section 232a, a driven constant speed section 232b and a driven acceleration section 232c end to end in a smooth manner in a clockwise direction. In the clockwise direction, the driven deceleration section 232a is a diverging curve, the driven constant velocity section 232b is an equal radius curve, and the driven acceleration section 232c is a converging curve.
After the spring 2351 of the elastic component stores elastic energy, the jumping stage is started, the driving motor 21 runs reversely, the spring 2351 contracts to release energy, when the energy is released, the upper end of the elastic component moves upwards, namely the upper ends of the first connecting rod 2352 and the second connecting rod 2353 move upwards, the steering wheel 36 and the main body bracket 1 move upwards, so that the circular gear 233 is driven to rotate upwards on the rack 234, the driven non-circular gear 232 rotates synchronously, in the process, the driven acceleration section 232c of the driven non-circular gear 232 is meshed with the driving deceleration section 231c of the driving non-circular gear 231, and the driven non-circular gear 232 and the driving non-circular gear 231 are in acceleration transmission due to the fact that the meshing of the driven non-circular gear 232 and the driving non-circular gear 231 has a special motion rule. The release of energy from the spring 2351 is accelerated, and at the moment of releasing the energy, the driven non-circular gear 232 and the driving non-circular gear 231 complete the speed-up transmission. The increased speed of the driven noncircular gear 232 and the driving noncircular gear 231 can accelerate the release of the energy of the spring 2351, so that the bouncing mechanism releases all the stored energy of the spring 2351 before leaving the ground as much as possible, thereby completely converting the elastic potential energy into kinetic energy.
After the jumping mechanism empties, the circular gear 233 continues to rotate on the rack 234, the driven constant-speed section 232b of the driven non-circular gear 232 is meshed with the driving constant-speed section 231b of the driving non-circular gear 231, and the driven non-circular gear 232 and the driving non-circular gear 231 perform constant-speed transmission. At this time, the circular gear 233 is engaged with an arc-shaped section of the upper end of the rack 234.
When the circular gear 233 rotates to another straight line segment of the rack 234, the circular gear 233 rotates downward along the straight line segment, the steering wheel 36 and the main body support 1 move downward, so that the upper end of the elastic assembly, i.e., the upper ends of the first link 2352 and the second link 2353 move downward, the spring 2351 is stretched again to store elastic energy, the bouncing mechanism retracts the leg in the air, the driven deceleration section 232a of the driven non-circular gear 232 is engaged with the driving acceleration section 231a of the driving non-circular gear 231 during leg retraction and landing, and the driven non-circular gear 232 and the driving non-circular gear 231 perform deceleration transmission. At the same time, the downward impact force of the bouncing mechanism upon landing may further stretch the spring 2351, effectively storing energy.
