Description

Technical Field

[0001] This utility model relates to the manufacturing industry, and in particular to a dual-density seat cushion that can be quickly installed. Background Technology

[0002] A bicycle, also known as a pedal bike or bike, is a small land transportation tool powered by human pedals. Bicycles are mainly used for commuting, fitness, and exercise, and have advantages such as being environmentally friendly, low-noise, and lightweight. Bicycles are usually equipped with a seat. The saddle of a commuter comfort model usually consists of a seat support frame and a saddle. The existing seat support frame is usually formed by a combination of a retaining ring, a saddle beam, and a bracket. During installation, the saddle beam needs to be pressed into the retaining ring first, and then the retaining ring is placed in the bracket to complete the overall installation of the seat support frame. Subsequently, the shock absorber mounting base is fixed to the base plate of the saddle with fastening screws or other methods. Finally, the seat support frame is fixed to the shock absorber mounting base with fastening screws. There are many parts to be installed, which requires skilled assemblers, has high time and labor costs, and is inconvenient to install. Utility Model Content

Shock-absorbing mounting seats that cooperate with the seat cushion support frame are provided on both sides of the lower part of the wide end of the saddle. A saddle beam mounting seat is provided at the narrow end of the saddle. A cover is provided above the saddle beam mounting seat. A saddle beam end locking member is provided between the saddle beam mounting seat and the cover, and at the inner bend of the saddle beam end. Bolts that cooperate with the saddle beam end locking member are fixedly connected to the saddle beam mounting seat. During installation, the end of the saddle beam is fixed by the saddle beam end locking member and the bolts.

[0005] Preferably, the seat cushion support frame is fixed to the shock-absorbing mounting base, and the cover is fixed to the saddle beam mounting base with fastening screws.

[0006] Preferably, the base plate and the shock-absorbing mounting base are integrally formed, further reducing the number of parts that assembly personnel need to install.

[0007] Preferably, a shock-absorbing device is provided between the seat support frame and the shock-absorbing mounting base to effectively reduce vibrations generated during riding and improve comfort.

[0008] Preferably, the saddle includes a base plate and a dual-density foam layer, the dual-density foam layer covering the top of the base plate, the dual-density foam layer consisting of a support layer and a comfort riding layer, the support layer being located below the comfort riding layer.

[0009] The beneficial effects of this utility model are that the injection-molded bracket, saddle beam, fixing ring and shock-absorbing mounting base integrally molded with the base plate can effectively reduce the installation steps of workers, greatly improve production efficiency, and reduce scrap rate while effectively reducing labor costs due to the reduction of parts.

[0012] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0013] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0014] like Figure 1-4The illustrated dual-density seat cushion, which can be quickly installed, includes a saddle 1 and a seat support frame 2. The saddle 1 includes a base plate 10 and a dual-density foam layer 11, with the dual-density foam layer 11 covering the top of the base plate 10. The seat support frame 2 is located below the saddle 1 and includes an integrally formed bracket 3, a saddle beam 4, and a fixing ring 14. Shock-absorbing mounting seats 5, which cooperate with the seat support frame 2, are provided on both sides of the lower part of the wide end of the saddle 1. A saddle beam mounting seat 6 is provided at the narrow end of the saddle 1. A cover 7 is provided above the saddle beam mounting seat 6. A saddle beam end locking member 15 for fixing the saddle beam 4 is provided between the saddle beam mounting seat 6 and the cover 7, and at the inner bend of the end of the saddle beam 4. A bolt 16, which cooperates with the saddle beam end locking member 15, is fixedly connected to the saddle beam mounting seat 6. During installation, the end of the saddle beam is fixed by the saddle beam end locking member and the bolt.

[0015] The saddle beam locking component 15 includes a nut and a spring washer.

[0016] The bracket 3 and the shock-absorbing mounting base 5, and the cover 7 and the saddle beam mounting base 6 are all fixed by fastening screws 8.

[0017] The base plate 10 and the shock-absorbing mounting base 5 are integrally formed, further reducing the number of parts that assembly personnel need to install.

[0018] A shock-absorbing device 9 is provided between the seat support frame 2 and the shock-absorbing mounting base 5. The shock-absorbing device 9 effectively reduces the vibration generated during riding and improves comfort.

[0019] The dual-density foam layer 11 consists of a support layer 13 and a comfort riding layer 12. The support layer 13 is located below the comfort riding layer 12. Existing foam layers are usually formed by foaming materials with the same foaming density. In order to achieve a specified thickness, a large amount of foaming material needs to be used for foaming. The foam layer is prone to being too thick, resulting in a hard foam layer. The dual-density foam layer 11 adopts the form of combining the inner support layer 13 and the comfort riding layer 12, which ensures support without affecting comfort and effectively controls the softness and hardness of the product. Furthermore, due to material characteristics, production process and raw material costs, the production price of the comfort riding layer 12 is usually higher than that of the support layer 13 for the same thickness. Therefore, under the same thickness, the dual-density foam layer 11 is cheaper and more comfortable than the single comfort riding layer 12. Specific Implementation

[0020] During installation, with the bottom of the saddle 1 facing upwards, first place the shock absorber 9 on the outside of the shock absorber mounting base 5, then place the seat cushion support frame 2 above the shock absorber mounting base 5, and connect the bracket 3 to the shock absorber mounting base 5 with the fastening screws 8. At this time, the end of the saddle beam 4 faces the saddle beam mounting base 6 and the bolt 16 is located at the inner bend of the end of the saddle beam 4. Tighten the saddle beam end locking piece 15 on the bolt 16 to lock the end of the saddle beam 4. Finally, cover the end of the saddle beam 4 with the protective cover 7 and lock it with the fastening screws 8 to complete the overall installation.

[0021] This design is ingenious. By using injection-molded brackets, saddles, fixing rings, and shock-absorbing mounting bases that are integrally molded with the base plate, the installation steps for workers can be effectively reduced, significantly improving production efficiency. Furthermore, due to the reduction in parts, labor costs are effectively reduced while the scrap rate is also lowered. In addition, the use of dual-density molding technology and the selection of cheaper foaming materials for the internal support layer compared to the external riding layer further reduces costs and enhances market competitiveness.

[0022] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
