Description

Technical Field

[0001] The utility model relates to the technical field of bicycle seats, in particular to a bicycle seat structure with adjustable angle. Background Art

[0002] The bicycle seat is an important structure of a bicycle. Its function is to allow the rider to sit on the bicycle while riding. When riding a bicycle on a city road, the bicycle may encounter a slope, causing the bicycle body and the rider's body to tilt. When the bicycle and the rider tilt, the overall center of gravity of the bicycle and the rider will change. The rider's sitting posture needs to be adjusted accordingly to alleviate the change in the center of gravity, thereby improving the riding comfort. Therefore, a bicycle seat structure with an adjustable angle is needed.

[0003] When adjusting the angle of the existing bicycle seat structure, it is necessary to rely on tightening screws and nuts to fix the angle of the seat cushion, which is laborious and time-consuming to adjust, and some bicycle seats do not have an angle adjustment function.

[0004] An angle-adjustable bicycle seat and bicycle are disclosed in publication number CN217623866U. Although the present application has the effect of adjusting the inclination of the seat body by lifting and lowering a lifting mechanism to adapt to the riding posture of the rider when going uphill, the contact area between the rider and the seat body is increased, and the riding comfort of the rider is improved.

[0005] However, the bicycle seat and bicycle with adjustable angle have the following disadvantages: the rider sits on the seat for a long time to do cycling exercises, and the seat has poor air permeability, which easily causes moisture in the middle of the buttocks, resulting in reduced comfort when sitting on the seat, and the rider's legs are stressed during pedaling, which easily pulls the seat left and right, causing irreversible damage to the seat over time. Utility Model Content

[0006] 1. Technical issues to be solved

[0007] The technical problem solved by the utility model is to provide a bicycle seat structure with an adjustable angle, which is highly practical and can be easily operated with a relatively simple structure. It solves the problems of labor-saving adjustment of the bicycle seat angle and improving the air permeability and strength of the seat cushion proposed in the above-mentioned background technology.

[0008] (II) Technical solution

[0009] To achieve the above objectives, the utility model is implemented through the following technical scheme: an angle-adjustable bicycle seat structure, comprising an oblique insertion rod, a receiving plate welded on the top of the oblique insertion rod, an adjustment frame fixedly welded on the top of the receiving plate, a threaded adjustment bolt rotatably connected inside the adjustment frame, an angle adjustment assembly threadedly connected on the surface of the threaded adjustment bolt, auxiliary rotation assemblies fixedly welded on both sides of the top surface of the receiving plate, a pressure plate fixedly welded on the top of the angle adjustment assembly and the auxiliary rotation assembly, a shock-absorbing spring fixedly connected on the top surface of the shock-absorbing spring, a cushion connecting plate fixedly connected on the top surface of the cushion connecting plate, a cushion fixedly connected on the top surface of the cushion, a ventilation groove is opened in the middle of the cushion, a ventilation mesh is fixedly installed inside the ventilation groove, and tie strips are fixedly installed on both sides of the ventilation groove.

[0010] Optionally, one end of the threaded adjustment bolt is fixedly connected to a rotating disk, and the surface of the threaded adjustment bolt is rotatably connected to the middle portion of the inner side of the adjustment frame.

[0011] Optionally, the angle adjustment assembly includes an active movable frame threadedly connected to the surface of a threaded adjustment bolt, the surface of the active movable frame is rotatably connected to an active rotating rod, the surface of the active rotating rod is rotatably connected to an active fixed frame, and the top end of the active fixed frame is fixedly welded to the bottom surface of the pressure plate.

[0014] Optionally, the surface of the seat cushion is made of leather, and the interior of the seat cushion is filled with sponge.

[0015] Optionally, there are seven tie strips, the seven tie strips are evenly distributed in a straight line on both sides of the air-permeable groove, and the tie strips are made of rubber.

[0016] (III) Beneficial effects

[0017] The utility model provides a bicycle seat structure with adjustable angle, which has the following beneficial effects:

[0018] 1. The bicycle seat structure with adjustable angle is arranged by the cooperation of the threaded adjustment bolt, the angle adjustment assembly and the auxiliary rotation assembly. When riding on uphill and downhill sections, the rider rotates the rotating disk to drive the threaded adjustment bolt to rotate inside the adjustment frame, so that the active moving frame threadedly connected to the threaded adjustment bolt moves, and the active fixed frame drives one end of the pressure plate to rise or fall, so that the seat structure can achieve the angle adjustment of the seat by turning the hand, and the adjustment method is fast and labor-saving.
