Description

Technical Field

[0001] This application relates to bicycle technology, specifically to a bicycle seat cushion. Background Technology

[0002] Bicycles are driven by alternating force exerted by both feet. The bicycle saddle is a key component of the riding system, playing a crucial role in support, force transmission, and cushioning. However, existing bicycle saddles are fixed to the frame and only have height adjustment functionality. During riding, the saddle repeatedly rubs against the rider during pedaling, easily causing redness, pain, and even skin abrasions.

[0003] When cycling, the body's center of gravity is on the saddle. However, cycling requires switching between left and right to generate power. To reduce friction between the sides of the seat and the thighs, the saddle is usually very narrow. However, the reduced contact area between the saddle and the buttocks increases the pressure per unit area, sacrificing comfort. Long-term cycling can easily cause soreness and numbness in the buttocks, and even compress the sciatic nerve. Secondly, adding soft materials to the saddle provides good cushioning but is easily deformed. When pedaling, the saddle shape is unstable, which increases the relative friction displacement between the thighs and the saddle.

[0004] In existing technologies, springs are added to the bottom of the seat to improve comfort, but this only provides good cushioning for vertical bumps and cannot solve the problem of lateral friction during riding. Summary of the Invention

[0005] This invention addresses the problem of friction between the human body and the saddle during cycling, as mentioned in the background section. It provides a bicycle saddle that can swing, thereby shifting the body's center of gravity relative to the bicycle and reducing friction between the body and the saddle.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bicycle saddle, comprising a fixing rod fixed to the frame and a fixing seat disposed on the fixing rod, wherein a saddle is disposed on the fixing seat and the saddle is hinged to the fixing seat, the saddle can swing left and right along the hinge point of the saddle, and the saddle can swing towards the side of the power foot so that the center of gravity is biased towards that side.

[0007] In this embodiment, a leg plate is hinged to the front edge of the seat cushion, and a transmission bridge is also hinged to the bottom of the seat cushion in the middle. The two ends of the transmission bridge are respectively hinged to the bottom of the leg plate on that side via connecting rods. The transmission bridge is also hinged to a fixed seat. When force is applied, the thigh on that side will push the leg plate to rotate downward along the hinge point, thereby driving the connecting rod to drive the transmission bridge to rotate along the transmission bridge-seat cushion hinge point. At this time, since the transmission bridge is also hinged to the fixed seat, the swing of the transmission bridge will drive the seat plate to rotate along the seat plate-fixed seat hinge point.

[0008] As one of the preferred options for bicycle saddles, the mounting base extends rearward, and the rear side of the drive axle is hinged to the mounting base.

[0009] As one of the preferred solutions for bicycle saddles, the fixed seat extends to both sides with extension arms, and the extension arms are equipped with first rollers for mounting the saddle, with the rollers set perpendicular to the hinge point of the saddle.

[0010] As one of the preferred options for bicycle saddles, the drive axle is equipped with second rollers at both ends that are rolled in conjunction with the saddle.

[0011] As one of the preferred options for bicycle saddles, the rear center of the leg rest is recessed, and the front edge of both sides of the saddle has an arc-shaped groove to avoid the thighs.

[0012] As one of the preferred options for bicycle saddles, the upper surface of the saddle has recessed points corresponding to the ischial tuberosities. These recessed points effectively limit the movement of the buttocks, preventing friction between the buttocks and the seat, and also smoothly guide the body's center of gravity to shift with the force exerted, preventing the saddle from only causing the skin of the buttocks to sway.

[0013] As one of the preferred solutions for bicycle saddles, the seat includes a base plate and pads located on the upper surface of the base plate and slidable laterally relative to the base plate, corresponding to the two sides of the buttocks. The base plate has shoulder holes, the pads are fixed to the shoulder holes and can slide along the shoulder holes, and also includes an adjusting nut. The adjusting nut is rotatably provided on the side of the base plate, and the base plate has an adjusting plate screwed to the adjusting nut.

[0014] As one of the preferred solutions for bicycle saddles, the upper end face of the drive axle is provided with a bearing groove, the lower end face of the drive axle is provided with a bearing groove, a flat bearing is provided between the drive axle and the saddle, and a flat bearing is provided between the hinge pin and the drive axle. The drive axle is clamped by two flat bearings, resulting in a more stable connection.

[0015] When using this invention, the body will shift when exerting force, and the seat cushion will shift with the body to the side of exertion, effectively avoiding friction between the buttocks and the seat cushion, and avoiding friction between the inner thighs and the seat cushion.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The seat can swing left and right with the side of the power foot, precisely conforming to the body's center of gravity shift trajectory when riding, greatly reducing the relative friction between the buttocks and the seat surface, avoiding skin redness and abrasion, while reducing the unit area pressure in the ischial tuberosity area, relieving soreness and numbness after long-term riding.

[0018] 2. The linkage mechanism between the leg rest and the drive axle triggers the seat angle adjustment through the natural downward pressing action of the thigh when exerting force, achieving a seamless connection between "force exertion and adjustment" without the need for active user control, thus improving the smoothness and naturalness of the riding process; the downward pressing action triggers the other leg rest to lift up, assisting the thigh to lift, which is more effortless;

[0019] 3. The first roller on the fixed seat extension arm and the second rollers at both ends of the transmission bridge effectively reduce the mechanical friction resistance during the swaying and sliding of the seat cushion, share the stress at the hinge, make the adjustment action smoother and quieter, and extend the service life of the components.

[0020] 4. The horizontally sliding double-sided pads, together with the side adjustment nuts, support personalized adaptation according to the width of different users' buttocks, enhance the fit between the seat cushion and the buttocks, and further optimize the efficiency of center of gravity transfer.

[0021] 5. The arc-shaped relief groove design at the ischium depression and the front of the saddle provides stable support and limit for the ischium area and provides space relief for the inner thigh, thus reducing friction damage in key areas and comprehensively improving riding comfort and safety.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0031] Example 1

[0032] like Figures 1-4 As shown, a bicycle saddle 3 has a fixing rod 1 fixed to the frame 11. A fixing seat 2 for mounting the saddle 3 is provided on the fixing rod 1. The saddle 3 is hinged to the fixing seat 2. The fixing seat includes a connecting rod 21 and a fixing piece 22 fixedly mounted to the connecting rod 21. The fixing rod 1 is provided with a clamping member 12 for clamping the connecting rod 21. When riding and exerting force, the saddle 3 can swing left and right, shifting the center of gravity to the side exerting force, just like the left and right swaying of the body when standing and riding. When the rider sits on the saddle 3, the buttocks will shift left and right with the exertion of force, and the saddle 3 can swing towards the side of the exerting foot, shifting the center of gravity to that side. This makes the body and the exertion of force more aligned, eliminating friction between the inner thighs and the saddle 3.

[0033] Example 2

[0034] This embodiment is an improvement on Embodiment 1. It should be noted that the following technical features are covered for a certain purpose, but are not essential technical features of this embodiment. For a certain simplification purpose, this part can be omitted. Based on Embodiment 1, the front edge of the seat cushion 3 is hinged to a leg plate 4, and a transmission bridge 5 is also hinged to the bottom of the seat cushion 3 in the middle. The two ends of the transmission bridge 5 are respectively hinged to the bottom of the leg plate 4 on that side through connecting rods 6. The transmission bridge 5 is also hinged to the fixed seat 2. The rear end of the connecting rod 2 of the fixed seat 2 is provided with a strip, and the transmission bridge 5 is hinged to the strip. When force is applied, the thigh on that side will push the leg plate 4 to rotate downward along the hinge point, thereby driving the connecting rod 6 to drive the transmission bridge 5 to rotate along the transmission bridge-seat cushion hinge point A. At this time, since the transmission bridge 5 is also hinged to the fixed seat 2, the swing of the transmission bridge 5 will drive the seat plate to rotate along the seat plate-fixed seat hinge point B. The fixed seat 2 extends backward, and the middle rear side of the transmission bridge 5 is hinged to the fixed seat 2 to form the transmission bridge-fixed seat hinge point C. As the transmission bridge 5 swings, since the fixed seat 2 is fixed, the transmission bridge-seat cushion hinge point A drives the rear end of the seat cushion to swing along the transmission bridge-fixed seat hinge point C towards the force-generating side.

[0035] In one embodiment, the leg plate 4 has a recess 41 at the center of its rear end, and the side cushions 3 have arc-shaped grooves 34 at the center of their front edges to avoid the thighs. The leg plate 4 with the recess 41 can adapt to the shape of the thighs, making it more comfortable to use.

[0036] In one embodiment, in order to share the connection pressure between the fixed seat 2 and the seat 3, this device can be omitted if the structural strength of the fixed seat 2 is sufficient, without affecting the use of this application; the strip of the fixed seat 2 extends to both sides with extension arms 32, and the extension arms 32 are provided with first rollers 33 for supporting the seat 3, and the rollers are set perpendicular to the hinge point of the seat 3.

[0037] In one embodiment, to further distribute the pressure on the seat plate, the transmission bridge 5 is provided with second rollers 51 at both ends, which are rolled with the seat cushion 3. The second rollers at both ends of the transmission bridge can both support the bottom of the seat cushion and, to a certain extent, distribute the force on the transmission bridge when the extension arm is driven.

[0038] In one embodiment, the upper surface of the seat cushion 3 is provided with a recess 41 corresponding to the ischium. The recess 41 effectively limits the movement of the buttocks and prevents friction between the buttocks and the seat point, and can smoothly drive the body's center of gravity to shift with the force applied, preventing the seat cushion 3 from only causing the skin of the buttocks to swing.

[0039] In one embodiment, the seat cushion 3 includes a base plate 30 and pads 31 located on the upper surface of the base plate 30 and slidable laterally relative to the base plate 30, corresponding to the two sides of the buttocks respectively. The base plate 30 is provided with shoulder holes 301, and the pads 31 are fixed on the shoulder holes 301 and can slide along the shoulder holes 301. It also includes an adjusting nut 323, which is rotatably provided on the side of the base plate 30. The base plate 30 is provided with an adjusting piece 324 screwed to the adjusting nut 323.

[0040] In one embodiment, the upper end face of the transmission bridge 5 is provided with a bearing groove, the lower end face of the transmission bridge 5 is provided with a bearing groove, a plane bearing 7 is provided between the transmission bridge 5 and the seat pad 3, and a plane bearing 7 is provided between the hinge shaft and the transmission bridge 5. The transmission bridge 5 is clamped by two plane bearings 7, making the connection more stable.

[0041] It should be understood that the specific embodiments described above are for illustrative purposes only and are not intended to limit the scope of the invention. Therefore, any modifications, equivalent substitutions, or improvements made without departing from the spirit and scope of the invention should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
