Description

Technical Field

[0001] The invention belongs to the field of mechanical engineering and relates to a bicycle seat cushion frame, a seat cushion and a bicycle. Background Art

[0002] Bicycle seats are generally divided into two types: (1) Narrow and long hard seats. This type of narrow hard seat is commonly found on sports bikes and is designed for high-speed cruising. When pedaling at high speed, a wide seat can easily rub against the inner thighs, causing pain and affecting pedaling movements. Therefore, it is designed to be narrow and long. Soft seats, on the other hand, cannot support the body steadily, which affects pedaling efficiency. The buttocks feel like they are stuck in a sofa. Second, the contact area between the soft seat and the buttocks is large. If you pedal fast, your buttocks will keep moving and will be painful due to excessive friction. Therefore, a hard seat is more suitable for fast pedaling movements. (2) Wide and soft comfort seats, which are commonly found on entry-level or leisure bikes and are designed for slow cruising. The wide design allows a larger and more even support area between the seat and the buttocks. The soft seat can provide better comfort. Due to the leisure-oriented pedaling movement, there is no need to consider the fact that a wide and soft seat is not suitable for high-speed pedaling.

[0003] The present invention is mainly aimed at the design defects of the seat cushion of the second use orientation or riding condition. For example, the seat cushion structure of the commonly seen shared bicycles in daily life is a wide and soft comfortable seat cushion (see Figure 1 ), riding for a long time (for example, more than half an hour) or occasionally accelerating will still cause buttocks fatigue and pain, and the riding experience is poor.

[0004] The main reason is that the bicycle seat structure has poor ability to adapt to the riding posture, uneven pressure on the buttocks or thighs, or unreasonable force. At present, there are new seat structures on the market, such as the VabsRider seat designed by Australian engineer Robin Macan in 2016 (see Figure 2 ), the biggest difference between the VabsRider and traditional saddles is the unique double-wing design, which can swing independently with the rider's legs, effectively relieving the pressure on the sitting bones and transferring it to the thigh bones, thereby achieving a more even distribution of force and reducing hip pain. It has to be said that the VabsRider saddle design is novel and practical, but the design is relatively complex, with high manufacturing precision and high manufacturing cost, and is still in the early stages of commercialization. Summary of the invention

[0005] The purpose of the present invention is to provide a bicycle seat frame, a seat and a bicycle, which solves the problem of how to reduce riding fatigue.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is: The present invention provides a bicycle seat frame, comprising a seat and two wing portions connected to the front edge of the seat, wherein the wing portions are distributed in the width direction of the seat, the wing portions are integral with the seat, and the connection between the wing portions and the seat is elastic. The wing portions themselves are also elastic so that they can bend in the front-to-back direction, the thickness of the wing portions gradually decreases from the back to the front, and a mounting seat is connected to the lower surface of the seat.

[0007] Preferably, there is a set distance between the two wings, and the set distance is equivalent to the width of the mounting seat.

[0008] Preferably, the thickness of the rear end of the wing portion is the same as the thickness of the front edge of the seat portion and the transition is smooth.

[0009] Preferably, the side edges of the seat portion are smoothly transitioned to the outer edges of the two wing portions respectively, and the inner edges of the two wing portions in the width direction are also smoothly transitioned to the front edge of the seat portion.

[0010] Preferably, the rear end corner of the seat portion and the front end corner of the wing portion are both in arc shape.

[0011] Preferably, a soft layer is adhered to the upper surface of the seat and / or the wing.

[0012] Preferably, the width of the seat and the distance between the outer edges of the two wing portions both tend to decrease from the rear end to the front end.

[0013] Preferably, the seat and the wing are both made of 51CrV4 spring steel.

[0014] A bicycle seat cushion is also provided, which uses the above-mentioned bicycle seat cushion frame, and the bicycle seat cushion frame is wrapped with a seat cover.

[0015] Also provided is a bicycle, which adopts the above-mentioned bicycle seat cushion.

[0016] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: The bicycle seat frame, seat and bicycle of the present invention include two wing parts, and the connection between the wing parts and the seat part is elastic. Therefore, the wing parts will swing down when the thighs are pressed down during pedaling, reducing the resistance of the thighs to the downward pressure, thereby alleviating riding fatigue. In addition, since the wing parts themselves are also bendable, and the thickness of the wing parts gradually decreases from the back to the front, the wing parts can better fit the thighs when they swing up and down, provide better support for the thighs, and reduce riding fatigue.

[0018] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 3 and Figure 4 The bicycle seat frame shown comprises a seat 1 and a wing 2 made of 51CrV4 spring steel. The wing 2 has two wing portions, which are located at the front edge of the seat 1 and distributed in the width direction. The wing portion 2 and the seat 1 are an integral structure and are made of a whole piece of spring steel.

[0020] The lower surface of the seat 1 is connected with a mounting seat 3. The two wings 2 are spaced apart by a set distance, which is equivalent to the width of the mounting seat 3, so that the position of the wings 2 matches the position of the rider's thigh. The mounting seat 3 is close to the front side of the seat 1.

[0021] from Figure 3 It can be seen that there is a cutting line at the junction of the seat 1 and the wing 2. Figure 4 It can be seen that the variable cutting line is formed by the reduction of the thickness of the wing 2. The thickness of the rear end of the wing 2 is the same as that of the seat 1, and the thickness of the wing 2 gradually decreases from the back to the front. The reduction in the thickness of the wing 2 makes it easy for the wing 2 to swing down around its rear end when the thigh is pressed down during riding. In addition, since the mounting seat 3 is close to the front side of the seat 1, it supports the seat 1, making the front edge of the seat 1 not easy to bend.

[0022] The wing 2 itself is also easy to bend. Figure 4Thus, when riding, the wing 2 provides better support for the thigh, which helps to reduce riding fatigue. The thickness of the wing 2 gradually decreases from the back to the front, which makes the wing 2 bend more evenly and can use its own elasticity to reset when the rider's thigh is lifted. The curvature of the wing 2 makes the wing 2 fit the thigh better, providing better support for the thigh during the dynamic process of riding, which further helps to reduce fatigue.

[0023] like Figure 3 As shown, there is a smooth transition between the outer edge of the seat 1 and the outer edges of the two wings 2, and there is also a smooth transition between the inner edges of the two wings 2 and the front edge of the seat 1. There is no step in the transition part between the wings 2 and the seat 1, which makes it difficult for cracks or even breaks to occur at the connection between the wings 2 and the seat 1 when the wings 2 swing around their rear ends.

[0024] like Figure 4 As shown, the upper surface of the wing 2 is flush with the seat 1, and the lower surface of the wing 2 gradually approaches the upper surface from the back to the front.

[0025] like Figure 4 As shown, a soft layer 4 is attached to the upper surface of the seat 1 and the wing 2. The soft layer 4 in this example is PU foam, but it can also be other soft materials. The outer surface of the bicycle seat frame is covered with a seat cover (not shown). The seat cover also forms a certain degree of compression on the PU foam, so that the PU foam adheres to the surface of the seat 1 and the wing 2.

[0026] from Figure 3 It can be seen that the rear corner of the seat portion 1 and the front corner of the wing portion 2 are both in arc shape, which prevents the seat cover wrapped outside from being damaged and also provides protection for the rider.

[0027] like Figure 3 The width of the seat 1 decreases from the back to the front, so that the seat 1 provides better support for the rider's buttocks. The distance between the outer edges of the two wings 2 also decreases from the back to the front, so that the wings 2 are easier to swing with the rider's thighs.

[0028] To sum up, when the bicycle seat frame of this example is used as a bicycle seat, the two wings 2 can swing with the swing of the rider's thighs, thereby reducing the resistance to the swing of the thighs and alleviating fatigue on the one hand, and on the other hand, the wings 2 form dynamic support for the rider's thighs, adapt to the riding posture, and reduce fatigue during long-term riding.

[0029] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
