Description

Technical Field

[0001] The invention belongs to the technical field of saddles, and in particular relates to a shock-absorbing saddle. Background Art

[0002] With the development of society, consumers have higher and higher requirements for the riding comfort of bicycles and electric bicycles. As the main component supporting the rider, the shock absorption performance of the saddle directly affects the riding comfort. The patent document with the authorization announcement number CN 209870616U discloses a shock-absorbing saddle, which includes a bottom shell, a seat cushion arranged on the top surface of the bottom shell, a support bow arranged on the bottom surface of the bottom shell, and a shock-absorbing mechanism arranged on the bottom surface of the rear part of the bottom shell. The shock-absorbing mechanism includes a shock-absorbing body and a fixing frame for fixing the shock-absorbing body. The shock-absorbing body is provided with two and arranged side by side at the rear part of the bottom shell. The fixing frame is covered on the shock-absorbing body and connected to the bottom shell. The shock-absorbing body is a regular hexagonal prism-type elastic body, and a fixing groove matching the shape of the shock-absorbing body is provided on the fixing frame. The shock-absorbing saddle cancels the traditional spring shock-absorbing structure and uses a new shock-absorbing body instead. The shock-absorbing body better balances the shock-absorbing performance and supporting performance of the saddle. There are various vibration-damping saddles on the market, and their general structure is that the front end of the saddle is fixed by the front end bolts of the support rod, and the rear end of the saddle is connected to the rear end of the support rod by various springs to achieve the purpose of vibration reduction. The patent document with the authorization announcement number CN 211809978 U discloses a transverse axis spiral vibration-damping saddle, including a seat plate and a bracket installed at the lower part of the seat plate, characterized in that: the bracket includes two beams arranged symmetrically below the seat plate, and the rear part of the beam is provided with a spiral part, and the axis of the spiral part extends horizontally. In the present invention, the bracket used to support the saddle seat plate has a spiral part, so that in addition to the supporting function, the bracket itself has a vibration-damping function, and there is no need to connect and assemble other vibration-damping components, thereby reducing the number of components in the lower part of the saddle, simplifying the vibration-damping structure, and eliminating the safety hazards caused by the connection stability between components. The patent document with authorization announcement number CN 211809980 U discloses a vertical circular shock-absorbing saddle, including a seat plate and a bracket installed at the lower part of the seat plate, characterized in that: the bracket includes two beams symmetrically arranged below the seat plate, and a vertical circular portion is provided at the rear of the beam, and the vertical circular portion includes a supporting beam section and a curved buffer beam section connected between the two supporting beam sections, and the supporting beam section and the curved buffer beam section are located on the same vertical plane.

[0003] Although the above structure can reduce shock through the spring, only the rear half of the saddle has a shock-absorbing effect. The reason is that the front end of the saddle is fixed during shock absorption. As the rear spring is compressed, the rear of the saddle can sink. As the spring moves up and down, the saddle moves in a "kowtow-like" motion. In fact, only half of the saddle is shock-absorbing, which greatly reduces the riding comfort.

[0004] In view of the defects of existing technologies and market demand, the saddle needs further improvement. Summary of the invention

The seat plate is made of materials used in conventional saddles, such as sponge, polyester, etc., which belongs to the conventional saddle process and will not be described in detail. The double U-shaped support rod is made of spring steel.

[0026] The preferred solution of this embodiment is that the rear cantilever of the support rod is composed of a straight cantilever and an S-shaped cantilever to form an extended rear cantilever, the front end of the extended rear cantilever is connected to the curved arc at the front end of the support rod, and the rear end of the straight cantilever is bent at a right angle to form the rear fulcrum axis of the support rod. The extended cantilever can increase the deformation of the spring component in the limited space of the saddle, reduce the stress at the curved arc, and improve the shock absorption amplitude.

[0027] The preferred solution of this embodiment is that the end of the cantilever on the rear side of the support rod is bent at a right angle to form a rear fulcrum axis of the support rod, the saddle fixing clip and the double U-shaped elastic support rod are clamped to form a fixed fulcrum, and the connection between the bracket and the front and rear ends of the double U-shaped elastic support rod is a movable fulcrum structure.

[0028] The preferred solution of this embodiment is that the bracket includes a bracket body, a support rod rear fulcrum mounting platform 2-1, a support rod limiting column 2-2 and a pressure cover 4, two support rod rear fulcrum mounting platforms are symmetrically arranged at the inner rear end of the bracket body, a support rod limiting column is arranged at the inner front end of the bracket body, the two support rod rear fulcrum mounting platforms and the support rod limiting column are arranged in a triangular shape, the support rod rear fulcrum mounting platform is provided with a long groove 2-4 along its axial direction, the support rod rear fulcrum axis rotates in the long groove, a limiting screw is arranged at the opening of the long groove, the limiting screw is blocked in front of the fulcrum rotating shaft, and the degree of freedom of the saddle to move forward and backward; the support rod limiting column is placed between the front cantilever arms of the two support rods at the front end of the double U-shaped elastic support rod, the front cantilever arms of the support rod slide, the support rod limiting column is connected to the pressure cover by a screw 5, and the support rod limiting column is composed of a limiting arc protrusion 2-3 and a central limiting column to form an integral structure. It plays a role in fixing the front end of the saddle, and at the same time, it plays a guiding role in the forward movement of the double U-shaped elastic support rod when the saddle is deformed by force. The support body is made of saddle plastic, such as ABS plastic. The support rod rear fulcrum mounting platform and the support rod limiting column are injection molded with the support body at one time.

[0029] The preferred solution of this embodiment is that the long slot of the support rod rear fulcrum mounting platform is opened forward or backward. Embodiment 1 is a structure in which the long slot of the support rod rear fulcrum mounting platform opens forward;

[0030] The purpose of the extended rear cantilever adopted in this embodiment is to extend the length of the rear cantilever of the support rod as much as possible within the limited space below the saddle, increase the length involved in deformation, increase the deformation amount, improve the shock absorption amplitude, reduce the stress at the bending arc, and enhance reliability. Of course, the solution of increasing the length of the rear cantilever of the support rod to participate in deformation is not limited to the S-shaped design of this embodiment.

[0031] See attached for details Figure 8 , 9 Embodiment 2 is a structure in which the long slot of the support rod rear fulcrum mounting platform opens backward. The long slot of the support rod rear fulcrum mounting platform is opened backward, the support rod rear fulcrum shaft slides forward and backward in the long slot, and the intersection arc of the left and right support rods at the front end of the double U-shaped elastic support rod rotates between the support rod limit column and the pressure cover.

[0032] The key technology of the present invention is that the shape of the double U-shaped spring component is centered on the fixed saddle fixing clip, and is folded back from the front of the saddle fixing clip to the rear to form a supporting cantilever at the rear end of the saddle, and is folded back from the rear of the saddle fixing clip to the front to form a supporting cantilever at the front end of the saddle. The two folds constitute a structure of an extended torsion spring working cantilever, which can not only ensure the installation space of the fixing clip, but also increase the shock absorption amplitude, thereby truly realizing the stable shock absorption effect of the saddle.

[0033] Working principle and working process

[0034] The saddle fixing clip 6 clamps the saddle fixing clip connecting arm 1-7 of the double U-shaped elastic support rod, and the clamping position within the saddle fixing clip connecting arm range can be adjusted forward and backward so as to adjust to the most comfortable position for different riders. The saddle fixing clip is fixedly connected to the bicycle saddle pipe by bolts to complete the installation of the saddle on the bicycle. Figure 1-2 As shown, with the saddle fixing clip connecting arm 1-7 as a fixed point, when the rider sits on the saddle, the double U-shaped elastic support rod supports the rider's weight through the front and rear three fulcrums, and the front / rear cantilever of the support rod undergoes a large deformation, and the front / rear end of the saddle can move up and down to provide shock absorption, so that the saddle can move up and down during the shock absorption process, providing the rider with a more comfortable riding effect. In Example 1, when the saddle moves downward, the rear fulcrum shaft 1-3 of the support rod rotates in the long groove, and the front cantilever 1-5 of the support rod slides with the limiting arc protrusion 2-3. In Example 2, when the saddle moves downward, the intersection arc 1-6 of the left and right support rods rotates between the support rod limiting column 2-2 and the pressure cover, and the rear fulcrum 1-3 of the support rod slides in the long groove.

[0035] The detailed description of the shock-absorbing saddle with reference to the above embodiment is illustrative rather than restrictive, and several embodiments can be listed according to the limited scope. Therefore, changes and modifications without departing from the overall concept of the present invention should fall within the scope of protection of the present invention.
