Description

Technical Field

[0001] This utility model relates to the field of mobility scooter technology, and in particular to a handlebar folding and fixing mechanism and a mobility scooter. Background Technology

[0002] When transporting or moving scooters, the steering handlebars typically need to be folded up to reduce their size and facilitate carrying. If the folded handlebars are not secured, they will swing left and right around the pivot point and up and down around the pivot point, directly affecting handling or transport. To address this, some folding scooters on the market are equipped with locking mechanisms; however, some of these mechanisms are prone to loosening and lack robustness.

[0003] For example, Chinese patent application CN201821280035.5 discloses a lightweight folding mobility scooter with front, rear, left, and right handlebars. Specifically, it discloses that "two or more T-handlebar latches 11 are installed on one side of the seat support frame for locking the folded T-handlebars. The T-handlebar latches are made of rubber, silicone, or plastic, and the ends of the T-handlebar latches have U-shaped, C-shaped, or semi-circular protrusions 12. The T-handlebar latches, through the friction between the rubber and the handlebars, can restrict the movement of the handlebars." This also secures the T-handlebars when folded. However, this design relies on friction for fixation, which is relatively weak; over time, the friction decreases, making it prone to loosening. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a handlebar folding and fixing mechanism that is not only sturdy and will not loosen, but also very convenient to lock and unlock, thereby overcoming the shortcomings of the existing technology.

Both the handlebar 10 and seat 30 can be folded onto the vehicle body 40. When the bicycle is folded, the seat 30 is folded onto the vehicle body 40, and then the handlebar 10 is folded onto the vehicle body 40, pressing down on the seat 30. When the handlebar 10 is folded, the hook 23 is hooked onto the hanging pin 38, so that the handlebar 10 will not loosen or wobble from side to side. When the vehicle needs to be unfolded, press button 27 to separate hook 23 and pin 38, at which point the handlebars 10 and seat 30 can be unfolded. Therefore, this hook 23 device 20 has a simple structure, is easy to operate, and the handlebars 10 will not loosen after locking, providing good stability.

[0035] Preferably, the hook 23 device 20 further includes a pin 21 and a torsion spring 22, with the pin 21 threaded through the hook 23 and the torsion spring 22; the hook 23 has an inclined surface 26; the hook pin 38 can slide along the inclined surface 26 into the hook 23 and be hooked by the hook 23.

The torsion spring 22 provides elasticity to the pin 21, allowing the hook 23 to swing. When the handlebar 10 is locked with the hook pin 38, the fixing head 37 is inserted into the hook opening 11, and the hook pin 38 slides along the inclined surface 26 into the hook 23. This locking structure operates very smoothly. The insertion of the fixing head 37 into the hook opening 11 also helps to position the handlebar 10, improving its stability after locking and preventing it from shaking. To unlock, press button 27 to release hook 23 from pin 38.

[0036] Preferably, the fixed seat 35 further includes a mounting part 36, and a fixing head 37 is integrally formed with the mounting part 36. The mounting part 36 is disposed on the seat 30. The fixing head 37 has a columnar structure. A hook 38 is disposed in the mounting groove of the fixing head 37. The mounting part 36 can be fixed to the seat base 32 with screws. The hook 38 can be assembled into the mounting groove of the fixing head 37 by press-fitting or threading. The fixing head 37 is inserted into the hook opening 11, which can prevent the handlebar 10 from wobbling from side to side and improve its firmness.

[0037] Preferably, a mounting ring 12 is embedded in the hook opening 11, and the fixing head 37 is inserted into the hook opening 11 through the mounting ring 12. The mounting ring 12 can be made of plastic material. The mounting ring 12 serves as a guide, allowing the fixing head 37 to be smoothly inserted into the hook opening 11, and also prevents the fixing head 37 from being scratched.

[0038] Preferably, the handlebar 10 is provided with a button hole; the button hole is inserted into the unlocking end of the hook 23; the button 27 is exposed in the button hole and can be pressed. The hook 23 has a hook portion 24 and a plug portion 25; a pin hole is provided in the middle of the hook 23; the pin 21 passes through the pin hole; the plug portion 25 is inserted into the button 27; the cross-section of the button 27 is frustoconical. The button 27 protrudes partially from the button hole, making it convenient for the operator to press. This design ensures that the button 27 is pressed into the button hole and will not loosen or fall off. The button 27 can be fixed to the plug portion 25 of the hook 23 by crimping, gluing, or plugging, making the assembly of the button 27 very convenient. The pin 21 and the hook 23 can be assembled by snap-fitting, welding, keyway connection, etc. The pin 21 passes through a torsion spring 22, which provides elasticity to the hook 23, ensuring that the hook 23 is hooked onto the pin 38 and will not loosen.

[0039] Preferably, the handlebar 10 includes a grip bar 13, a handlebar body 14, a base 15, and a hydraulic rod 16. The base 15 is rotatably mounted on the vehicle body 40 and connected to the front wheel on the base 15. The hydraulic rod 16 is hinged to the handlebar body 14 and the base 15. The grip bar 13 is mounted on the handlebar body 14. The handlebar 10 is T-shaped. The hydraulic rod 16 is telescopic. The grip bar 13 is mounted on the handlebar body 14. When the handlebar body 14 is unfolded from the base 15, the hydraulic rod 16 provides support for the handlebar body 14 and the base 15, allowing the handlebar body 14 to be unfolded. When the hydraulic rod 16 is retracted, the handlebar body 14 can fold on the base 15, thereby allowing the handlebar 10 to fold onto the vehicle body 40.

[0040] Preferably, the seat 30 includes folding chair legs 31, a seat base 32 hinged to the folding chair legs 31, a seat cushion 34 disposed on the seat base 32, and armrests 33 hinged to the folding chair legs 31; the hook 38 is disposed on the seat base 32. The folding chair legs 31 are hinged to the vehicle body 40. There are two sets of folding chair legs 31, and their structure is similar to a quadrilateral structure, such as a parallelogram. The quadrilateral structure can be folded, so the folding chair legs 31 can be folded onto the vehicle body 40. The seat base 32 is also hinged to the folding chair legs 31, so the seat base 32 can also be folded onto the vehicle body 40. The armrests 33 can be folded backward onto the vehicle body 40, and the seat base 32 can be folded forward onto the vehicle body 40. The hook 38 is located in the middle of the rear side of the seat base 32, which facilitates the hook 23 to be hooked onto the hook 38. Because the handlebar 10 is a T-shaped handlebar, the handlebar 10 will not wobble when the hook 23 is attached to the scraper, and the handlebar 10 will not loosen, so it is very secure.

[0041] When the handlebar 10 is folded down, the handlebar 10 rotates downward around the handlebar pivot point 17. When the head of the fixing seat 35 enters the hook opening 11, the inclined surface 26 on the hook 23 contacts the hook pin 38. When pressed down further, the hook 23 will automatically hook the hook pin 38 under the action of the torsion spring 22. The hook opening 11 and the head of the fixing seat 35 also fit into place, and the handlebar 10 is firmly locked.
