[0034] In one embodiment of this utility model, such as Figure 1-6 As shown, an adjustable seat cushion is provided, comprising: a base pad 1, a top pad 2, an opening 3, and an adjustment assembly 4. The top pad 2 is disposed on top of the base pad 1 and is used to position the cushion body; the opening 3 is formed in the base pad 1; the adjustment assembly 4 includes a rotating shaft 401, a worm gear, and a worm 403. The rotating shaft 401 is positioned at the bottom of the top pad 2, the worm gear is sleeved on the rotating shaft 401, and the worm 403 is rotatably and vertically disposed on the base pad 1, and the worm 403 passes vertically through the opening 3 to mesh with the worm gear; wherein, rotating the worm 403 drives the worm gear to rotate, and the rotating shaft 401 and the worm gear rotate synchronously, thereby causing the top pad 2 to adjust its angle.

[0035] The adjustable seat provided by this utility model achieves precise micro-adjustment of the top pad 2 angle through the meshing transmission of a worm gear 403 and a worm wheel. Riders can adjust the seat angle in minute increments according to their needs, facilitating finding the optimal support angle during cycling and other activities, thus improving the seat's adaptability. The worm gear 403 is integrated into the bottom pad 1, where the opening 3 of the bottom pad 1 meshes with the worm wheel of the top pad 2 to achieve the angle adjustment function. The angle adjustment component 4 is hidden inside the seat, avoiding exposure and ensuring a smooth overall shape. In cycling scenarios, it does not occupy the limited space around the seat, nor does it hinder the rider's leg movement, ensuring riding comfort and flexibility while maximizing space utilization efficiency.

[0036] In this embodiment, when installing the pad, it can be installed according to the size of the top pad 2, or the size can be increased and installed on the top pad 2, thereby blocking the connecting parts between the bottom pad 1 and the top pad 2.

[0037] In this embodiment, the rotating shaft 401 is positioned at the center of the top pad 2, and the axis of the rotating shaft 401 is parallel to the axis of the top pad 2, which ensures that the top pad 2 is subjected to uniform force during angle adjustment. When the rider adjusts the seat angle, the top pad 2 rotates around the rotating shaft 401 in the center, avoiding swaying or displacement caused by eccentric force and providing stable and reliable support for the rider. The worm gear is sleeved on the rotating shaft 401, and the axis of the worm gear coincides with the axis of the rotating shaft 401, ensuring smooth power transmission. The worm 403 passes vertically through the opening 3 and meshes with the worm gear. The axes of the worm gear and the rotating shaft 401 are both perpendicular to the axis of the worm 403, further ensuring smooth power transmission.

[0038] The adjustable angle seat cushion also includes a connecting component 5 disposed on the bottom surface of the top pad 2, the connecting component 5 being used to connect the top pad 2 and the worm gear.

[0039] Specifically, the connecting assembly 5 includes a mounting plate 501, a housing 502, a shaft 503, and a positioning plate 504. The mounting plate 501 is positioned on the top surface of the bottom pad 1, and the housing 502 and the shaft 503 are respectively positioned on the two sides of the mounting plate 501. The worm gear is disposed inside the housing 502, and the worm 403 extends into the housing 502 to mesh with the worm gear. The worm gear being disposed inside the housing 502 provides effective protection for the worm gear. When meshing with the worm 403 extending into the housing 502, it effectively prevents the worm gear from shaking and displacing during operation, ensuring the stability of power transmission. The axis of the shaft 503 coincides with the axis of the worm gear, and the positioning plate 504 is positioned at the bottom of the top pad 2. The shaft 503 rotatably passes through the positioning plate 504. This ensures a secure and reliable connection between the top pad 2 and the worm gear. During angle adjustment, the top pad 2 can accurately follow the rotation of the worm gear to adjust the angle without any disconnection or loosening, providing riders with a consistently stable angle adjustment experience.

[0040] Preferably, the bottom surface of the bottom pad 1 is provided with an auxiliary component 6, which is used to assist the worm gear 403 in rotating.

[0041] Specifically, the auxiliary component 6 includes an auxiliary plate 601 and a bearing seat 602, providing assistance for the rotation of the worm gear 403. The auxiliary plate 601 is positioned on the bottom surface of the base pad 1, and the bearing seat 602 is positioned on the side of the auxiliary plate 601. The worm gear passes through the bearing seat 602 and the opening 3 from the bottom of the base pad 1 and meshes with the worm gear. The bearing seat 602 reduces the friction when the worm gear 403 rotates, making it easier for the rider to adjust the angle and improving the user experience. Moreover, the auxiliary component 6 further enhances the connection stability between the base pad 1 and the angle adjustment component 4, making the entire seat plate more reliable during use.

[0042] This adjustable seat also includes a shock absorber 7 connected between the bottom pad 1 and the top pad 2. The shock absorber 7 is used to reduce vibration when the rider sits on the top pad 2. The shock absorber 7 connected between the bottom pad 1 and the top pad 2 effectively reduces the vibration generated when the rider sits on it.

[0043] Specifically, the shock absorber 7 includes a first connecting shaft 701, a second connecting shaft 702, a telescopic rod 703, and a spring 704. The first connecting shaft 701 and the second connecting shaft 702 are respectively disposed on the top surface of the bottom pad 1 and the bottom surface of the top pad 2. The telescopic rod 703 connects the first connecting shaft 701 and the second connecting shaft 702, and the spring 704 is sleeved around the periphery of the telescopic rod 703. The shock absorber 7 is provided in several groups, and at least one group of the shock absorbers 7 is inclined from the bottom pad 1 toward the top pad 2. Preferably, at least one group of the shock absorbers 7 symmetrically forms a first reverse tension group with respect to the transverse centerline of the top pad 2, and the first reverse tension group symmetrically forms a second reverse tension group with respect to the longitudinal centerline of the top pad 2.

[0044] The telescopic rod 703 and spring 704 in the shock absorber 7 work together to absorb and disperse vibration energy. In particular, when multiple sets of shock absorbers 7 are distributed in a specific manner, such as at least one set of shock absorbers 7 tilting from the bottom pad 1 toward the top pad 2 and forming a reverse tension group symmetrically with respect to the lateral and longitudinal center lines of the top pad 2, vibration can be buffered from multiple directions, providing the rider with a more stable and comfortable seating experience and reducing fatigue caused by prolonged sitting.

[0045] Preferably, a handwheel 8 is positioned at the end of the worm gear 403, and the handwheel 8 is used to manually rotate the worm gear. The handwheel 8 at the end of the worm gear 403 makes it convenient for the rider to manually rotate the worm gear 403. Without the need for additional tools, the seat angle can be easily adjusted by simply turning the handwheel 8.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
