Description

Technical Field

[0001] This utility model relates to a mobility scooter, and more particularly to an angle-adjustable control lever for the mobility scooter. Background Technology

[0002] Existing mobility scooters typically feature adjustable control levers. By adjusting the lever's angle, the distance between the lever and the scooter's seat, as well as the height of the control handle, can be adjusted to suit users of different body types. However, traditional mobility scooters generally use pneumatic springs for adjustment. Specifically, the control lever and pneumatic spring are combined into a deformable bracket. When the pneumatic spring extends or retracts, it controls the deformation of the entire bracket, thereby moving the control lever to a certain angle for adjustment. However, due to the high cost and weight of pneumatic springs, this method results in a higher overall cost and heavier weight for the mobility scooter, presenting significant drawbacks. Utility Model Content

[0003] The purpose of this invention is to provide a simple, easy-to-operate, and low-cost adjustable control lever for a mobility scooter.

[0004] To achieve the above objectives, the adjustable angle control lever for a mobility scooter provided by this utility model includes a control lever, a connecting seat, a locking member, a connecting rod, and a base. The lower end of the control lever is pivotally connected to one end of the base, and the connecting seat is fixed to the control lever, with a sliding groove provided on the connecting seat. The lower end of the connecting rod is pivotally connected to the other end of the base, and the upper end of the connecting rod is slidably disposed in the sliding groove via a pin. The locking member is pivotally connected to the connecting seat, and one end of the locking member is provided with a locking part, which locks the pin to the opposite ends of the sliding groove.

[0005] Compared with existing technologies, this utility model, by setting a connecting seat, a connecting rod, and a base, allows the locking rod to be connected between the connecting seat and the base respectively. A sliding groove is provided on the connecting seat, allowing the upper end of the connecting rod to be slidably positioned in the groove via a pin. This creates a variable quadrilateral structure where the connecting seat, connecting rod, base, and control rod form, enabling the control rod to swing at a certain angle. Furthermore, a locking element is provided, using its locking part to lock the pin to opposite ends of the sliding groove. Therefore, the control rod has two lockable angle positions, achieving angle adjustment. The entire adjustable control rod has only two adjustment positions, a simple structure, and is easy to use. Moreover, it eliminates the need for a pneumatic spring, significantly reducing costs and making the vehicle lighter and easier to carry.

[0006] Preferably, the locking part has a bent structure toward the connecting seat, and the bent structure forms a limiting part at one end toward the slide groove. When the pin slides to one end of the slide groove, the limiting part clamps and locks the pin with one end of the slide groove. The bent structure forms a pressing part at the other end of the slide groove. When the pin slides to the other end of the slide groove, the pressing part clamps and locks the pin with the other end of the slide groove.

[0007] Preferably, the upper end of the connecting rod extends symmetrically into fork arms, and the pin is connected between the fork arms. By setting the upper end of the connecting rod into a fork arm structure, a space is formed between the pin and the connecting rod for the locking part to pass through, thereby allowing the limiting part to clamp the pin together with the other end of the slide groove.

[0008] Specifically, a pressing surface is provided between the two fork arms. When the pressing part clamps and locks the pin at the other end of the slide groove, the pressing part presses against the pressing surface. By the mutual contact and pressing between the pressing surface and the pressing part, the frictional resistance of the locking part can be increased, thereby preventing the locking part from swinging and achieving the purpose of locking the locking member. Therefore, the pin can be locked at one end of the slide groove, thereby locking the angle of the control lever, preventing the pin from being accidentally unlocked, and improving the safety of use.

[0009] Preferably, a limiting protrusion extends from the locking member, and a limiting pin is provided on the connecting seat. When the locking member rotates to lock the shaft pin, the limiting protrusion abuts against the limiting pin. This prevents the locking member from rotating excessively, ensures the accuracy of the locking member's position when locked, and improves the convenience of operation.

[0010] Preferably, an elastic element is provided between the locking part and the connecting seat, the elastic element providing an elastic force to bring the locking member closer to the pin. This allows the locking member to automatically lock the pin and prevents the locking member from accidentally releasing the pin, improving operational convenience and safety.

[0011] Preferably, the other end of the locking member extends outward to form an operating handle. The operating handle makes it easier for the operator to rotate the locking member, thus improving operational convenience.

[0012] Preferably, the locking member extends with a limiting protrusion, and the connecting seat is provided with a limiting post. When the locking member locks the shaft pin, the limiting protrusion abuts against the limiting post. Through the cooperation between the limiting protrusion and the limiting post, excessive rotation of the locking member can be prevented, ensuring the stability of the shaft pin locking.

[0018] To explain in detail the technical content, structural features, and effects achieved by this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0019] like Figures 1 to 3 As shown, the adjustable angle control lever 100 of this utility model includes a control lever 1, a connecting seat 2, a locking member 3, a connecting rod 4, and a base 5. The control lever 1 has a telescopic structure, and the lower end of the control lever 1 is pivotally connected to one end of the base 5. The connecting seat 2 is fixed to the control lever 1 and is provided with a sliding groove 21. The lower end of the connecting rod 4 is pivotally connected to the other end of the base 5, and the upper end of the connecting rod 4 is slidably disposed in the sliding groove 21 via a shaft pin 41. The locking member 3 is pivotally connected to the connecting seat 2 via a pivot shaft 3a, and one end of the locking member 3 is provided with a locking part 31, which locks the shaft pin 41 to the opposite ends of the sliding groove 21.

[0020] Please see again Figure 2 and Figure 3 The locking part 31 has a bent structure toward the connecting seat 2, and a limiting part 32 is formed at one end of the bent structure toward the slide groove 21. When the pin 41 slides to one end 21a of the slide groove 21, the limiting part 32 clamps and locks the pin 41 with the end 21a of the slide groove 21. The other end of the bent structure toward the slide groove 21 forms a pressing part 33. When the pin 41 slides to the other end 21b of the slide groove 21, the limiting part 33 clamps and locks the pin 41 with the other end 21b of the slide groove 21.

[0021] Please see again Figure 2 and Figure 3The upper end of the connecting rod 4 extends symmetrically into fork arms 42, and the pin 41 is connected between the fork arms 42. By setting the upper end of the connecting rod 4 into a fork arm 42 structure, a space is formed between the pin 41 and the connecting rod 4 for the locking part 31 to pass through, so that the pressing part 33 can clamp the pin 41 together with the other end of the slide groove 21. Specifically, there is a pressing surface 43 between the two fork arms 42. When the limiting part 32 clamps and locks the pin 41 with one end 21a of the slide groove 21, the pressing part 33 presses against the pressing surface 43. By the contact and pressing between the pressing surface 43 and the pressing part 33, the frictional resistance of the locking part 31 can be increased, thereby preventing the locking part 31 from swinging and achieving the purpose of locking the locking member 3. Therefore, the pin 41 can be locked at one end of the slide groove 21, thereby locking the angle of the control rod 1, preventing the pin 41 from being accidentally unlocked, and improving the safety of use. Conversely, when the pressing part 33 clamps and locks the shaft pin 41 with the other end 21b of the sliding groove 21, the pressing part 33 presses against the surface of the shaft pin 41, thereby increasing the frictional resistance of the locking part 31, preventing the locking part 31 from swinging, and achieving the purpose of locking the locking member 3.

[0022] Please see again Figure 2 and Figure 3 The locking member 3 extends a limiting protrusion 35, and the connecting seat 2 is provided with a limiting pin 22. When the locking member 3 rotates to lock the shaft pin 41, the limiting protrusion 35 abuts against the limiting pin 22. This can prevent the locking member 3 from rotating excessively, ensure the accuracy of the locking member 3's position when locked, and improve the convenience of operation.

[0023] Please see again Figure 2 An elastic element 5 is provided between the locking part 31 and the connecting seat 2. The elastic element 5 provides an elastic force to bring the locking member 3 closer to the shaft pin 41. The elastic element 5 is a torsion spring, which is sleeved on the pivot shaft 3a with one end abutting against the locking part 31 and the other end abutting against the connecting seat 2. This allows the locking member 3 to automatically lock the shaft pin 41 and prevents the locking member 3 from accidentally releasing the shaft pin 41, improving the convenience of operation and the safety of use.

[0024] Please see Figure 3 The other end of the locking member 3 extends outward to form an operating handle 34. The operating handle 34 makes it easier for the operator to rotate the locking member 3, thereby improving the convenience of operation.

[0025] Combination Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, when the angle of the control lever 1 needs to be adjusted, first rotate the locking member 3 by operating the handle 34, so that the locking part 31 moves away from the pin 41. At this time, the pin 41 is in an unlocked state, so the control lever 1 can be swung to change its angle. At this time, the pin 41 moves from one end of the slide groove 21 to the other end. Then, rotate the locking lever again, so that the locking part 31 moves closer to the pin 41 and locks the pin 41. For example, when the control lever 1 is adjusted to an angle away from the seat, the pin 41 slides to the lower end 21b of the slide groove 21. At this time, the pressing part 33 presses against the pin 41, and the pressing part 33 and the lower end 21b of the slide groove 21 together lock the pin 41. When the control lever 1 is adjusted to an angle close to the seat, the pin 41 slides to the upper end 21a of the groove 21. At this time, the limiting part 32 engages with the pin 41, and the pressing part 33 presses against the pressing surface 43. Thus, the limiting part 32 and the upper end 21a of the groove 21 together lock the pin 41. To release the lock, simply rotate the locking member 3 away from the pin 41.

[0026] Compared with the prior art, this utility model, by setting a connecting seat 2, a connecting rod 4, and a base 5, allows the locking rod to be connected between the connecting seat 2 and the base 5 respectively. Furthermore, a sliding groove 21 is provided on the connecting seat 2, allowing the upper end of the connecting rod 4 to be slidably positioned in the sliding groove 21 via a pin 41. This creates a variable quadrilateral structure for the connecting seat 2, connecting rod 4, base 5, and control rod 1, enabling the control rod 1 to swing at a certain angle. A locking member 3 is also provided, using a locking part 31 on the locking member 3 to lock the pin 41 to the opposite ends of the sliding groove 21. Therefore, the control rod 1 has two lockable angle positions, achieving angle adjustment. The entire adjustable control rod 100 has only two adjustment positions, a simple structure, and is easy to use. Moreover, it eliminates the need for a pneumatic spring, significantly reducing costs and making the mobility scooter lighter and easier to carry.

[0027] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
