Description

Technical Field

[0001] The invention relates to the field of tricycles, and in particular to a steering assist device and a handlebar mechanism for a tricycle. Background Art

[0002] A tricycle is a vehicle with three wheels, usually consisting of two driving wheels and one driven wheel. This type of vehicle is widely used in various occasions, such as cargo transportation, personnel transportation, and special operations. Electric tricycles use electric motors as a power source, which has the advantages of environmental protection, energy saving, and easy operation. They are widely used in urban logistics, express delivery and other fields. With the continuous advancement of technology and the increasingly standardized management, the performance and safety of electric tricycles will also be further improved.

[0003] As an environmentally friendly, convenient and economical means of transportation, electric tricycles have broad application prospects and development potential in the market. In the prior art, the handlebars of tricycles are mostly fixed with nuts. When the handlebars of tricycles need to be disassembled for maintenance or replacement of parts, the operator needs to use special tools to disassemble the handlebars, and certain skills and experience are required, which is more difficult for users who are not familiar with mechanical operation. At the same time, the handlebars of tricycles are prone to disassembly difficulties and parts loss during the disassembly process. When the handlebars of tricycles are installed again, the failure rate of tricycles will increase, reducing the safety of tricycles. When the tricycles are loaded with heavy objects, the steering system will be under greater pressure, so that the tricycles become abnormally heavy during the steering process. The driver needs to pay more physical and mental effort during driving, which increases the driver's fatigue, reduces the environmental adaptability and control performance of the tricycles, and increases the energy consumption of the tricycles.

At this time, the handlebar 1 is assembled and connected with the steering mechanism 5 and the sensing mechanism 4. At this time, the ball head 306 on the lower surface of the shell 303 is against the hemispherical groove on the upper surface of the steering shaft 507. Use a wrench to tighten the four closing bolts 404. The quick-release mechanism 3 optimizes the fixing method of the tricycle handlebar 1, reduces the failure rate of the tricycle, and improves the safety of the tricycle.

[0029] After the quick-loading mechanism 3 is connected and fixed with the steering mechanism 5 and the sensing mechanism 4, when the sensing mechanism 4 senses the position of the quick-loading mechanism 3, the handlebar 1 is rotated, and the handlebar 1 rotates to one side to drive the locking seat 2 to rotate to one side, and the locking seat 2 rotates to one side to drive the housing 303 to rotate to one side, and the housing 303 rotates to one side to drive the positioning magnet 311 to rotate to one side. When the induction sensor 402 on one side senses the change of the magnetic field, it outputs a corresponding electrical signal to the steering mechanism 5. When the handlebar 1 is rotated to the other side, the handlebar 1 drives the positioning magnet 311 to rotate to the other side. When the induction sensor 402 on the other side senses the change of the magnetic field, it also outputs a corresponding electrical signal to the steering mechanism 5. The sensing mechanism 4 reduces the rotation resistance of the handlebar 1 and reduces the work intensity of the driver at the same time.

[0030] After the sensing mechanism 4 senses the rotation angle of the handlebar 1, the signal is transmitted to the steering mechanism 5, the steering motor 501 is started, the output end of the steering motor 501 drives the driving gear 502 to rotate, the driving gear 502 is meshed and connected with the reduction gear 503, the driving gear 502 rotates to drive the reduction gear 503 to rotate, the reduction gear 503 rotates to drive the reduction shaft 509 to rotate, the reduction shaft 509 rotates to drive the toggle gear 504 to rotate, the toggle gear 504 is meshed and connected with the steering gear 505, the toggle gear 504 rotates to drive the steering gear 505 to rotate, and the limit The position column 506 limits the rotation angle of the steering gear 505 to prevent the tricycle from turning at too large an angle and causing the tricycle to overturn. The rotation of the steering gear 505 drives the steering shaft 507 to rotate, and the rotation of the steering shaft 507 drives the fixed clamping plate 6 to rotate. The rotation of the fixed clamping plate 6 drives the shock absorbing mechanism 8 to rotate, and the rotation of the shock absorbing mechanism 8 drives the walking mechanism 10 to rotate. When the tricycle is loaded with heavy objects, the steering mechanism 5 assists the tricycle in steering, thereby reducing the driver's fatigue, improving the environmental adaptability and controllability of the tricycle, and reducing the energy consumption of the tricycle.

[0031] When the tricycle is traveling, the speed of the tricycle is adjusted by the speed regulating mechanism 11. The handle 1101 is rotated by hand, and the rotation of the handle 1101 drives the magnet 1104 to rotate. The rotation of the magnet 1104 causes the torsion spring 1103 to contract under force. The magnet 1104 rotates and approaches the Hall element 1105, causing the magnetic field strength to change. After the Hall element 1105 senses the change in the magnetic field, it will output a corresponding electrical signal. The driving speed of the tricycle is controlled by the distance between the magnet 1104 and the Hall element 1105. The appropriate driving speed helps to ensure the controllability of the tricycle.

[0032] When encountering an uneven road surface, the shock absorbing mechanism 8 offsets the vibration of the traveling mechanism 10, and the traveling mechanism 10 drives the shock absorbing seat 801 to reciprocate up and down, and the reciprocating motion of the shock absorbing seat 801 drives the cylinder sleeve 802 to reciprocate up and down, and the reciprocating motion of the cylinder sleeve 802 compresses and stretches the shock absorbing spring 803, and the reciprocating motion of the cylinder sleeve 802 drives the piston rod 804 to reciprocate up and down, and the reciprocating motion of the piston rod 804 pushes the active piston 807 to reciprocate up and down, and the reciprocating motion of the active piston 807 compresses the nitrogen between the active piston 807 and the driven piston 809, and the compressed nitrogen continues The continued up and down reciprocating motion pushes the driven piston 809 to reciprocate up and down. The up and down reciprocating motion of the driven piston 809 compresses the nitrogen between the driven piston 809 and the cylinder body 805. The contraction and extension of the shock-absorbing spring 803 offset the vibration of the walking mechanism 10. At the same time, by compressing the nitrogen, the driving comfort of the tricycle is improved and the smooth operation of the tricycle is ensured. The dustproof sealing ring 806 prevents dust from entering the cylinder body 805, causing the piston rod 804 to get stuck, resulting in the failure of the shock-absorbing mechanism 8. The oil sealing ring 808 prevents the nitrogen in the cylinder body 805 from leaking, causing the failure of the shock-absorbing mechanism 8.

[0033] When it is necessary to disassemble and maintain the handlebar 1 of the tricycle or replace parts, and to release the connection and fixation between the quick-install mechanism 3 and the steering mechanism 5 and the sensing mechanism 4, the unlocking handle 301 is pressed downward, and the unlocking handle 301 slides downward inside the shell 303. The unlocking handle 301 slides downward to drive the locking block 302 to slide out of the square groove of the circular ring groove on the upper side of the shell 303, and then the unlocking handle 301 is twisted 90 degrees, and the unlocking handle 301 slides in the circular ring groove on the upper side of the shell 303 to the square slide groove connected by the two circular ring grooves. Under the action of the L-shaped slide groove on the lower surface of the unlocking handle 301, the L-shaped ring does not rotate when the unlocking handle 301 rotates, and the unlocking handle 301 is continued to be pushed downward to drive the unlocking column 304 to slide downward. The unlocking column 304 slides downward to compress the reset spring 305, and the unlocking column 304 slides downward to drive the guide block 307 to slide in the square groove on the inner side of the shell 303. The unlocking column 304 slides downward and drives the four unlocking shafts 310 to slide downward. Under the action of the square bevel groove of the limit block 308, the unlocking shaft 310 slides downward and drives the two limit blocks 308 to slide toward each other. The two limit blocks 308 slide toward each other and compress the limit spring 309. After the two limit blocks 308 shrink into the shell 303, the unlocking handle 301 is twisted to drive the locking block 302 to slide into the circular ring groove on the lower side of the shell 303. At this time, the unlocking handle 301 is rotated another 90 degrees, and the unlocking handle 301 is released. The return spring 305 releases the pressure to push the unlocking column 304 to slide upward. The unlocking column 304 slides upward and drives the unlocking handle 301 to slide upward. The unlocking handle 301 slides upward and drives the two locking blocks 302 to be stuck in the square groove on the side of the circular ring groove on the lower side of the shell 303. At this time, the handlebar 1 can be removed, and the handlebar 1 can be disassembled for maintenance and parts replacement.
