Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, and in particular to a ride-on lawnmower. Background Technology

[0002] Ride-on lawnmowers, a common type of lawn mowing equipment, are widely used in lawn maintenance in courtyards, parks, golf courses, and large green belts due to their ride-on operation, wide working range, and high mowing efficiency. Compared to handheld or push-type lawnmowers, ride-on lawnmowers are directly controlled by the rider, reducing manual labor intensity to some extent while increasing the working area per unit time, making them one of the most commonly used equipment in large-scale lawn maintenance.

[0003] In the structural design of ride-on lawnmowers, the steering wheel is a key component for achieving directional control. It is usually connected to the transmission components of the steering system (such as the steering shaft) through a fixed connection structure (such as bolt fastening, welding or one-piece molding). This connection method has its conventional considerations in ensuring stability and reliability during operation and is also a common design choice in existing technology.

[0004] From a practical application perspective, the existing fixed-connection steering wheel structure may reveal room for optimization in certain scenarios after long-term use. For example, the presence of the steering wheel may impact space utilization during equipment transportation and storage; the fixed state of the steering wheel may limit operational convenience during maintenance and repair; and the fixed structure may offer improved adaptability to different user operating habits or special operational needs. Therefore, this paper explores a ride-on lawnmower with a detachable steering wheel structure while ensuring steering wheel control stability. Utility Model Content

[0023] The present invention will be further described in detail below with reference to specific embodiments:

[0024] Figures 1 to 7 This invention discloses one embodiment of the riding lawnmower proposed in this utility model.

[0025] Combination Figures 1 to 4 Embodiment 1 includes a chassis 1 and a seat 2, a console assembly, a steering gear assembly, and a steering rod reinforcement assembly mounted on the chassis 1. The console assembly includes a console housing 3, a steering wheel 4, and a coupling seat 5. The steering gear assembly includes a steering rod 6. The steering rod reinforcement assembly includes a bracket 7 and a pair of bearing seats 8. The console housing 3 has a coupling seat mounting hole 9, and the coupling seat 5 is rotatably mounted in the coupling seat mounting hole 9. The coupling seat 5 has a downward-opening steering rod connection hole 10, and the upper end of the steering rod 6 is inserted and fixed in the steering rod connection hole 10. The lower end of the steering wheel 4 has a quick-release head 11, which is detachably fixed to the coupling seat 5, making the steering wheel 4 in Embodiment 1 detachable. This provides anti-theft protection against misuse by others, especially children, and offers personalization. Advantages such as improved user experience: a pair of bearing seats 8 are fixedly connected to brackets 7, and brackets 7 are fixedly connected to the console housing 3. The steering rod 6 is rotatably inserted into a pair of bearing seats 8 to enhance the stability of the steering rod 6. The upper end of the steering wheel 4 is the highest point in Embodiment 1. The seat 2 includes a backrest 20 and a seat 21. The backrest 20 is rotatably mounted on the seat 21. A limiting pivot is connected between the backrest 20 and the seat 21. When the backrest 20 has the maximum rotation angle, it forms a right angle or a certain obtuse angle with the seat 21. The backrest 20 is restricted and cannot continue to rotate, so it can be used by the user to sit and lean against. When the backrest 20 has the minimum rotation angle, it fits against the seat 21, so that the overall height of the machine is further reduced significantly after the steering wheel 4 is removed, greatly improving the utilization of storage and transportation space.

[0026] Combination Figures 1 to 5The coupling seat 5 is provided with a coupling post 12, and the side wall of the coupling post 12 is provided with a number of ball grooves 13. The quick-release head 11 includes a quick-connect tube 14, a locking ring 15, and an elastic element 16. The side wall of the quick-connect tube 14 is provided with a number of ball holes 17, and the ball holes 17 are provided with radially movable balls 18. The locking ring 15 is fitted onto the outside of the quick-connect tube 14 and is held in the locked position under the elastic force of the elastic element 16, and squeezes the balls 18 to block the inner opening of the ball holes 17. The coupling post 12 is precisely inserted into the quick-connect tube 14. The number of balls 18 and the number of ball grooves 13 are consistent, their shapes and sizes are matched, and they correspond one-to-one and engage. The locking ring 15 can move axially under the action of an external force opposite to the elastic force of the elastic element 16 until it disengages from all the balls 18 and reaches the unlock position, so that the connecting post 12 and the quick-connect pipe 14 are disengaged from the fixed connection. There are 8 balls 17, 8 balls 13, and 8 balls 18. They are irregularly arranged in the circumferential direction, with 3 on one side and 5 on the other side. This ensures that the connecting seat 5 and the quick-release head 11 can be successfully locked at a unique relative angle and the locking is more secure. Therefore, both the connecting seat 5 and the quick-release head 11 are provided with alignment marks 19 to indicate that they are rotated into place, which also prevents the center position of the steering wheel 4 from being misaligned after installation.

[0027] Combination Figures 1 to 7The steering assembly also includes a steering wheel 22 and a drawbar 23. The lower end of the steering rod 6 is provided with a gear part 24. The middle part of the steering wheel 22 is rotatably mounted on the chassis 1. One side of the steering wheel 22 is provided with a gear plate part 25 that meshes with the gear part 24. The other side is hinged to one end of the drawbar 23. Embodiment 1 also includes a front suspension assembly and a pair of front wheels 26. The front suspension assembly includes an active swing arm 27, a crossbar 28, a linkage rod 29, a pair of pivot shafts 30, a pair of passive swing arms 31, and a pair of wheel axles 32. The pair of wheel axles 32 are always located on the same horizontal line. The pair of front wheels 26 are rotatably mounted on the pair of wheel axles 32. Both ends of the crossbar 28 are provided with vertical bearing parts 33. The pivot shaft 30 is rotatably mounted in the bearing part 33. Its lower end is fixedly connected to the passive swing arm 31 and the wheel axle 32. Both ends of the linkage rod 29 are respectively hinged to a pair of active swing arms 27. The upper end of one pivot shaft 30 is fixedly connected to one end of the passive swing arm 31, and the other end of the drawbar 23 is hinged to the other end of the active swing arm 27. The shaft 30, passive rotating arm 31, wheel axle 32, and front wheel 26 on the side adjacent to the traction rod 23 are referred to as the first shaft 30, first passive rotating arm 31, first wheel axle 32, and first front wheel 26. The other side is referred to as the second shaft 30, second passive rotating arm 31, second wheel axle 32, and second front wheel 26. When the user operates the steering wheel 4, the rotation of the steering wheel 4 is converted into the synchronous rotation of a pair of front wheels 26 through the transmission chains of "steering wheel 4 → steering lever 6 → steering wheel 22 → traction rod 23 → active rotating arm 27 → first shaft 30 → first wheel axle 32 → first front wheel 26" and "steering wheel 4 → steering lever 6 → steering wheel 22 → traction rod 23 → active rotating arm 27 → first shaft 30 → first passive rotating arm 31 → linkage rod 29 → second passive rotating arm 31 → second shaft 30 → second wheel axle 32 → second front wheel 26", thereby achieving directional control.
