Description

Technical Field

[0001] This utility model belongs to the field of bicycle saddle technology, and in particular relates to a novel bicycle seat frame. Background Technology

[0002] With the increasing popularity and improvement of modern people's environmental protection and fitness concepts, the trend of using bicycles as a means of transportation is becoming more and more popular. The bicycle saddle is an important part of the bicycle. Its core function is to support the body weight, improve riding comfort, optimize riding posture, and to a certain extent affect riding efficiency and safety, providing a guarantee for cyclists to ride for a long time.

[0003] Most existing bicycle saddles and saddle brackets are assembled and connected by bolts or slots. Although bolted connections are highly reliable, they are less efficient to assemble. Slotted connections are more efficient to assemble, but less reliable, and the saddle bracket may come loose from the slot.

[0004] Therefore, we need to design a new type of bicycle seat frame to solve these problems. Utility Model Content

[0005] The problem to be solved by this utility model is to provide a novel bicycle seat frame.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A novel bicycle seat frame includes an upper saddle, a lower saddle, and a saddle bracket. The upper saddle has a latch at its front end, and the lower saddle has an assembly groove at its front end. An insertion groove is provided through the side wall of the assembly groove, and a fixing rod is provided on the lower saddle on one side of the assembly groove. The saddle bracket has a insertion groove and a fixing hole. When the upper saddle, the lower saddle, and the saddle bracket are assembled together, the insertion groove is inserted into the assembly groove through the insertion groove, and the free end of the fixing rod passes through the fixing hole. The latch is inserted into the insertion groove within the assembly groove.

[0008] This design, through the multi-directional engagement of the latch, mounting slot, insertion slot, plug-in slot, and fixing rod, forms a three-dimensional fixed connection. The engagement of the latch and the plug-in slot prevents the saddle from sliding horizontally, while the fixing rod passing through the fixing hole restricts vertical displacement. The nested design of the plug-in slot and the mounting slot enhances the overall torsional resistance. This combination not only simplifies the assembly process but also ensures that the components do not easily loosen during bumpy rides, significantly improving structural stability and riding safety.

[0009] Preferably, the upper saddle is provided with a support seat at its front end, and the latch is fixedly disposed at the bottom of the support seat.

[0010] This design structurally isolates the latch from the upper saddle body, preventing direct stress on the latch and thus deformation of the upper saddle. Simultaneously, the support base acts as a stress-distributing transition structure, evenly transferring the external force borne by the latch to the entire upper saddle. Furthermore, the independent support base facilitates future maintenance and replacement; if the latch is worn or damaged, only the support base needs to be removed for individual repair, reducing maintenance costs and operational complexity.

[0011] Preferably, a fixed seat is provided on the lower saddle, a support column is provided on the top of the fixed seat, the support column matches the support groove, and the fixing rod is provided at the bottom of the fixed seat.

[0012] This design integrates the support column and fixing rod into a single unit. Through the dual positioning of the support column and support groove, and the fixing rod and fixing hole, precise assembly of the lower saddle and saddle bracket is achieved. This structure not only ensures quick positioning during assembly but also forms a stable triangular support structure during riding, effectively distributing pressure from different directions, improving the load-bearing capacity of the lower saddle, and extending its service life.

[0013] Furthermore, the upper saddle is also provided with a support groove, the position of which is opposite to the position of the support column.

[0014] This design, where the support groove and support column align, acts as a guide during assembly, facilitating quick alignment of the upper and lower saddles and improving assembly efficiency. Simultaneously, the tight fit effectively distributes the shear force on the fixing rod, reducing the risk of single-point stress and enhancing the overall structure's fatigue resistance. Furthermore, a buffer layer can be installed on the inner wall of the support groove to further absorb riding vibrations and improve comfort.

[0015] Preferably, a gripping assembly is also fixedly installed on the lower saddle on one side of the fixed rod.

[0016] This design, with the addition of the grip assembly, greatly improves the ease of assembly and adjustment. Riders or maintenance personnel can easily move and flip the saddle using the grip assembly, avoiding the risk of slipping due to the smooth surface. At the same time, the non-slip design of the grip assembly provides a reliable point of leverage when riders temporarily adjust the saddle angle, reducing operational errors and improving the user experience.

[0017] Preferably, reinforcing ribs are fixedly provided on the surface of the upper saddle and / or the surface of the lower saddle.

[0018] This design, with its optimized mechanical distribution on the saddle surface, significantly enhances the saddle's rigidity and resistance to deformation. The reinforcing rib layout, designed based on stress analysis, effectively improves the saddle's load-bearing capacity without adding excessive weight, making it particularly suitable for heavy-duty riding or high-intensity bumpy road conditions. Furthermore, the reinforcing ribs also act as flow guides, helping the plastic material flow evenly during injection molding, reducing molding defects, and improving production yield.

[0019] Preferably, the upper saddle is provided with a number of bolt holes, and the lower saddle is provided with a number of through holes. The number of through holes is the same as the number of bolt holes, and their positions correspond one-to-one.

[0020] This design, with its corresponding bolt holes and through holes, provides redundant securing. Multiple bolt connections disperse localized stress, preventing overall loosening due to single-point failure. Furthermore, this design allows for flexible adjustment of connection strength based on actual needs; by increasing or decreasing the number of bolts or replacing them with different specifications, it can adapt to different usage scenarios and load-bearing requirements. In addition, the standardized hole design facilitates rapid integration with other accessories (such as saddle bag brackets), enhancing the saddle's expandability.

[0021] The advantages and positive effects of this utility model are:

[0022] This utility model provides a latch on the upper saddle, a slot on the saddle bracket, and an assembly slot on the lower saddle where the slot on the mounting bracket can be inserted. After assembly, the latch can be inserted into the slot, thus achieving the assembly and connection of the upper saddle, lower saddle, and saddle bracket. This achieves the efficiency of a slot connection while maintaining the reliability of a bolt connection. Furthermore, the overall structure is simple, easy to maintain, and has a wide range of applications. Attached Figure Description

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] The present invention will be further described below with reference to the accompanying drawings:

[0036] Example 1: As Figures 1-7 As shown, a novel bicycle seat frame includes an upper saddle 1, a lower saddle 2, and a saddle bracket 3. The upper saddle 1 has a latch 5 at its front end, and the lower saddle 2 has an assembly groove 6 at its front end. An insertion groove 7 is provided through the side wall of the assembly groove 6. A fixing rod 13 is provided on the lower saddle 2 on one side of the assembly groove 6. The saddle bracket 3 has a plug groove 8 and a fixing hole 9. When the upper saddle 1, lower saddle 2, and saddle bracket 3 are assembled together, the plug groove 8 will be inserted into the assembly groove 6 through the insertion groove 7, and the free end of the fixing rod 13 will pass through the fixing hole 9. The latch 5 will be inserted into the plug groove 8 in the assembly groove 6.

[0037] A three-dimensional fixed connection is formed through the multi-directional engagement of the latch 5, mounting groove 6, insertion groove 7, plug-in groove 8, and fixing rod 13. The engagement of the latch 5 and the plug-in groove 8 prevents the saddle from sliding horizontally, while the fixing rod 13, passing through the fixing hole 9, restricts vertical displacement. The nested design of the plug-in groove 8 and the mounting groove 6 enhances the overall torsional resistance. This combination not only simplifies the assembly process but also ensures that the components are not easily loosened during bumpy rides, significantly improving structural stability and riding safety.

[0038] A support base 4 is provided at the front end of the upper saddle 1, and the latch 5 is fixedly mounted on the bottom of the support base 4. The support base 4 provides structural reinforcement and isolation between the latch 5 and the main body of the upper saddle 1, preventing the latch 5 from being directly subjected to force and causing deformation of the upper saddle 1. At the same time, the support base 4 can also serve as a stress-distributing transition structure, evenly transferring the external force borne by the latch 5 to the entire upper saddle 1. In addition, the independent support base 4 facilitates later maintenance and replacement. If the latch 5 is worn or damaged, it can be repaired separately by simply removing the support base 4, reducing maintenance costs and operational difficulty.

[0039] Specifically, the support base 4 and the latch 5 are integrally formed with the upper saddle 1. The latch 5 has a trapezoidal cross-section, with a design that is wider at the top and narrower at the bottom. This design ensures that the latch 5 is stably installed while effectively dispersing the pressure from the upper saddle 1 and avoiding localized stress concentration. The edges are polished to ensure a tight fit with the insertion slot 8 and to prevent scratches on the component surface during assembly.

[0040] A fixing seat 11 is provided on the lower saddle 2. A support column 10 is provided on the top of the fixing seat 11, and the support column 10 matches the support groove 12. A fixing rod 13 is provided at the bottom of the fixing seat 11. The fixing seat 11 integrates the support column 10 and the fixing rod 13. Through the dual positioning of the support column 10 and the support groove 12, and the fixing rod 13 and the fixing hole 9, the lower saddle 2 and the saddle bracket 3 can be precisely assembled. This structure not only ensures quick positioning during assembly, but also forms a stable triangular support structure during riding, effectively dispersing pressure from different directions, improving the load-bearing capacity of the lower saddle 2, and extending its service life.

[0041] Specifically, the mounting base 11 adopts a hollow honeycomb structure design, which significantly reduces weight while ensuring strength. The top of the support column 10 is cylindrical, which can provide stable support. The fixing rod 13 is made of high-strength stainless steel with an anti-rust coating. Its free end is machined with external threads, which can be used with nuts for tightening, ensuring that the assembled structure is firm and reliable.

[0042] The upper saddle 1 is also provided with a support groove 12, which is positioned opposite to the support rod. This allows the support groove 12 to mate with the support column 10, providing a guiding function during assembly and assisting in the quick alignment of the upper saddle 1 and lower saddle 2, thus improving assembly efficiency. Simultaneously, the tight fit between the two effectively distributes the shear force on the fixing rod 13, reducing the risk of single-point stress and enhancing the fatigue resistance of the overall structure. Furthermore, a buffer layer can be installed on the inner wall of the support groove 12 to further absorb riding vibrations and improve comfort.

[0043] Specifically, the support groove 12 is cylindrical and matches the support column 10. The inner wall is finely polished, and the depth is precisely matched with the fixing rod 13. A buffer rubber pad is also provided at the bottom of the support groove 12. When the support column 10 is inserted, the rubber pad can play a shock-absorbing and buffering role, reducing the loosening of parts caused by vibration during riding.

[0044] A gripping assembly 14 is also fixedly installed on the lower saddle 2 on one side of the fixed rod 13. The gripping assembly 14 consists of an anti-slip rubber sleeve and an internal skeleton. The skeleton is integrally formed with the lower saddle 2. The surface of the rubber sleeve is designed with a wave-shaped anti-slip texture. The depth and spacing of the texture have been ergonomically tested to provide a comfortable and stable grip when the rider adjusts the position of the bicycle. At the same time, the rubber sleeve has good wear resistance and weather resistance, adapting to different usage environments.

[0045] The addition of the grip assembly 14 greatly improves the ease of assembly and adjustment. Riders or maintenance personnel can easily move and flip the saddle using the grip assembly 14, avoiding the risk of slipping due to the smooth surface. At the same time, the anti-slip design of the grip assembly 14 provides a reliable point of leverage when riders temporarily adjust the saddle angle, reducing operational errors and improving the user experience.

[0046] Reinforcing ribs 17 are fixedly provided on the surface of the upper saddle 1 and / or the surface of the lower saddle 2. The reinforcing ribs 17 are distributed in a cross-shaped mesh and are integrally molded from high-strength plastic of the same material as the saddle body through injection molding. By optimizing the mechanical distribution on the saddle surface, the rigidity and deformation resistance of the saddle are significantly enhanced.

[0047] The height and width of the reinforcing rib 17 are designed differently according to the stress conditions of different parts of the saddle. In the edges and center areas with high stress, it can effectively improve the load-bearing strength of the saddle without adding too much weight, making it especially suitable for heavy-load riding or high-intensity bumpy road conditions. Furthermore, the reinforcing rib 17 can effectively improve the overall deformation resistance and load-bearing strength of the saddle, extending its service life.

[0048] In addition, the reinforcing rib 17 can also play a guiding role, helping the plastic raw material to flow evenly during injection molding, reducing molding defects and improving the yield rate.

[0049] The upper saddle 1 has several bolt holes 16 fixedly installed, and the lower saddle 2 has several through holes 15. The number of through holes 15 is the same as the number of bolt holes 16, and their positions correspond one-to-one. The corresponding design of bolt holes 16 and through holes 15 provides redundant fixing protection. Multiple sets of bolt connections can distribute local stress and avoid overall loosening due to single-point failure. Both bolt holes and through holes 15 adopt a countersunk hole design. When the bolt passes through the through hole 15 and is screwed into the bolt hole 16, the bolt head can be completely recessed into the hole, keeping the saddle surface flat and preventing it from scratching the rider's clothing. The inner wall of the bolt hole 16 is machined with internal threads. In this embodiment, the diameter of the through hole 15 is slightly larger than the bolt diameter by 0.5mm to ensure that the bolt can pass through smoothly and to ensure a tight fit after assembly.

[0050] Meanwhile, this design allows for flexible adjustment of connection strength according to actual needs. By increasing or decreasing the number of bolts or replacing them with different specifications, it can be adapted to different usage scenarios and load-bearing requirements. In addition, the standardized hole design facilitates quick integration with other accessories (such as saddle bag brackets), improving the saddle's expandability.

[0051] The working process of this embodiment is as follows: When assembling the bicycle saddle of this application, the insertion groove 8 on the saddle is first inserted into the insertion groove 7 so that the insertion groove 8 enters the assembly groove 6. Then, the fixing rod on the lower saddle 2 is passed through the fixing hole 9 and fixed with bolts.

[0052] Next, the upper saddle 1 and the lower saddle 2 are fastened together, so that the latch 5 on the upper saddle 1 enters the assembly groove 6 and is inserted into the insertion groove 8, locking the saddle bracket 3 and preventing the insertion groove 8 from sliding out of the assembly groove 6. At the same time, the support column 10 on the upper saddle 1 will enter the support groove 12 on the upper saddle 1, forming a stable support. Finally, after passing the bolt through the through hole 15 on the lower saddle 2, it is screwed into the bolt hole to complete the assembly of the saddle.

[0053] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
