Description

Technical Field

[0001] The utility model relates to the field of bicycles, in particular to a frame structure of a bicycle made of a ceramic-aluminum new material. Background Art

[0002] As one of the green means of transportation, bicycles do not need to consume fuel, electricity and other energy, and the travel cost is extremely low. They are very popular in cities with smooth roads. However, bicycles still have some shortcomings, such as the inconvenience of carrying items. Some bicycles are equipped with a basket at the front, but the longitudinal dimension of the basket is small, and long items are easy to slip out of the basket during riding, which is more likely to lose items and restrict their use. Therefore, there is a need for a bicycle frame that is more convenient for carrying items. Utility Model Content

[0003] Aiming at the defects in the prior art, the function of the bicycle frame is increased, and the frame material is improved to enhance the structural strength. The utility model provides a frame structure of a bicycle made of ceramic aluminum new material, including a saddle riser, an upper beam, a lower beam and a V-shaped rear fork beam; wherein the saddle riser, the upper beam and the lower beam are connected in sequence to form a triangular bracket, and the two ends of the V-shaped rear fork beam are respectively connected to the upper part and the lower part of the saddle riser; the two sides of the triangular bracket are respectively provided with detachable shielding members, and each shielding member does not exceed the upper beam, so as to form a cargo cavity with an upper end opening between the saddle riser, the lower beam and the two shielding members.

[0004] The beneficial effects of the device are as follows: the cargo chamber is arranged inside the triangular bracket, which does not occupy the riding space and does not affect the normal riding. On the other hand, the cargo chamber has a large longitudinal space, which is particularly suitable for long objects, such as fishing rods, screwdrivers, document bags, umbrellas, etc. The design of the upper opening makes it easy to take and put, and convenient to use. Compared with the existing bicycle basket, the objects are sandwiched between the two shielding parts, and the possibility of the objects slipping and losing is greatly reduced, which is safer.

[0005] Preferably, the two shielding members are both in the shape of a triangle, two of the three sides of each shielding member are detachably connected to the saddle seat tube and the lower beam, and the other side is located below the upper beam. Each shielding member is detachably connected to the saddle seat tube, and each shielding member is detachably connected to the lower beam via a connecting belt. In the case of carrying items while riding, the shielding members on both sides of the triangular bracket can be installed through the connecting belt, and vice versa, the shielding members on both sides can be removed through the connecting belt, which is convenient for disassembly and assembly.

[0006] Preferably, the inner side surface of the connecting belt is provided with a plurality of elastically deformable rubber nails, and all the rubber nails are evenly distributed along the length direction of the connecting belt. The saddle seat pipe and the lower beam are provided with mounting holes corresponding to all the rubber nails one by one. Specifically, an enlarged anti-dropout ball is provided in the middle of each rubber nail, and the anti-dropout ball is integrated with the rubber nail. The material of the anti-dropout ball is also rubber, which is elastically deformable. After the end of the rubber nail is inserted into the mounting hole, the anti-dropout ball is squeezed and inserted, and the entire rubber nail is fully inserted. Since the diameter of the anti-dropout ball is larger than the mounting hole, under normal circumstances, the anti-dropout ball cannot fall off from the mounting hole. Only by pulling the rubber nails outwards one by one can they fall off, thereby forming a detachable and installable structure, which can be used selectively according to needs.

[0007] Preferably, the cross-section of the connecting belt is in an arc shape, so that the inner surface of the connecting belt fits with the saddle seat tube or the lower beam. Since the saddle seat tube and the lower beam are both circular tubes or elliptical tubes, in order to make the connecting belt fit completely with the saddle seat tube and the lower beam, the inner surface of the connecting belt is formed into an arc surface for full fit.

[0008] Preferably, the shielding member is an elastic net bag, an elastic cloth or a baffle. The elastic net bag and the elastic cloth both have a certain elasticity and can accommodate some large items, while the baffle does not have elastic deformation and can accommodate some sharp items. The type of shielding member is selected according to the needs to meet most of the carrying situations of items.

[0009] Preferably, the two connecting belts on the same side of the triangular bracket are integrated, and the edge of each shielding member is fixedly connected to the corresponding connecting belt, so that the connecting belt on the same side of the triangular bracket is integrated with the shielding member. The connecting belt and the shielding member are integrated to form an accessory to avoid excessive and scattered parts.

[0010] Preferably, the materials of the saddle seat tube, upper beam, lower beam and V-shaped rear fork beam are all ceramic aluminum composite materials. Existing bicycle frame materials include steel, carbon fiber, etc., but the steel frame itself is very heavy, which increases the riding weight. Although the carbon fiber frame is light in weight, the cost is too high and the popularity rate is low. The use of ceramic aluminum composite materials as the frame material not only meets the strength requirements, hardness requirements, corrosion resistance requirements, etc., but is also light in weight and cheaper than carbon fiber, making it a new generation of bicycle materials.

[0021] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0022] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0023] like Figure 1As shown, this embodiment provides a frame structure of a ceramic aluminum new material bicycle, including a saddle riser 1, an upper beam 2, a lower beam 3 and a V-shaped rear fork beam 4; wherein the saddle riser 1, the upper beam 2 and the lower beam 3 are connected in sequence to form a triangular bracket, and the two ends of the V-shaped rear fork beam 4 are respectively connected to the upper and lower parts of the saddle riser 1. The materials of the saddle riser 1, the upper beam 2, the lower beam 3 and the V-shaped rear fork beam 4 are all ceramic aluminum composite materials. The existing bicycle frame materials include steel, carbon fiber, etc., but the steel frame itself is very heavy, which increases the riding load. Although the carbon fiber frame is light in weight, the cost is too high and the popularity rate is low. The use of ceramic aluminum composite materials as the frame material not only meets the strength requirements, hardness requirements, anti-corrosion requirements, etc., but is also light in weight and cheaper than carbon fiber, as a new generation of bicycle materials.

[0024] In order to facilitate carrying of items and minimize the probability of items slipping and being lost, in this embodiment, detachable shielding members 5 are respectively provided on both sides of the triangular bracket, and each shielding member 5 does not exceed the upper beam 2, thereby forming a cargo cavity with an upper end opening between the saddle seat tube 1, the lower beam 3 and the two shielding members 5. Specifically, the shielding member 5 is an elastic net bag, an elastic cloth or a baffle. Figure 3 , Figure 4 As shown in the figure, the elastic net pocket and elastic fabric have a certain elasticity and can hold some larger items. Figure 2 As shown, the baffle does not have elastic deformation and can accommodate some sharp objects. The type of shielding member 5 is selected according to the needs to meet the carrying conditions of most items.

[0025] The specific connection method of the shielding member 5 in this embodiment is as follows:

[0026] like Figure 3 , Figure 5 , Figure 6As shown, the two shielding members 5 are both in the shape of a triangle, and two of the three sides of each shielding member 5 are detachably connected to the saddle seat tube 1 and the lower beam 3, respectively, and the other side is located below the upper beam 2. Each shielding member 5 is detachably connected to the saddle seat tube 1, and each shielding member 5 is detachably connected to the lower beam 3 through a connecting belt 6. In the case where it is necessary to carry items while riding, the shielding members 5 on both sides of the triangular bracket can be installed through the connecting belt 6. Conversely, the shielding members 5 on both sides can be removed through the connecting belt 6, which is convenient for disassembly and assembly. Furthermore, a plurality of elastically deformable rubber nails 7 are provided on the inner side of the connecting belt, and all the rubber nails 7 are evenly distributed along the length direction of the connecting belt 6. The saddle seat tube 1 and the lower beam 3 are both provided with mounting holes 9 corresponding to all the rubber nails 7. Specifically, an enlarged anti-slipping ball 8 is provided in the middle of each rubber nail 7, and the anti-slipping ball 8 is integrated with the rubber nail 7. The material of the anti-drop ball 8 is also rubber, which can be elastically deformed. After the end of the rubber nail 7 is inserted into the mounting hole 9, the anti-drop ball 8 is squeezed and inserted, and the entire rubber nail 7 is fully inserted. Since the diameter of the anti-drop ball 8 is larger than the mounting hole 9, under normal circumstances, the anti-drop ball 8 cannot fall off from the mounting hole 9. Only by pulling out the rubber nails 7 one by one can they fall off, thus forming a detachable and installable structure, which can be selectively used according to needs.

[0027] like Figures 6 to 8 As shown, since the saddle seat tube 1 and the lower beam 3 are both circular tubes or elliptical tubes, in order to make the connecting belt 6 completely fit with the saddle seat tube 1 and the lower beam 3, the cross-sectional shape of the connecting belt 6 in this embodiment is an arc shape, so that the inner surface of the connecting belt 6 is fully fitted with the saddle seat tube 1 or the lower beam 3.

[0028] In addition, in order to reduce the number of accessories and avoid the problem of increased difficulty in assembly and easy loss of parts due to too many accessories, the two connecting belts 6 on the same side of the triangular bracket are integrated, and the edge of each shielding member 5 is fixedly connected to the corresponding connecting belt 6, so that the connecting belt 6 on the same side of the triangular bracket is integrated with the shielding member 5. The connecting belt 6 and the shielding member 5 are integrated to form an accessory to avoid excessive and scattered parts.

[0029] The cargo chamber in this embodiment is arranged inside the triangular bracket, which does not occupy the riding space and does not affect the normal riding. It can also expand the longitudinal space of the cargo chamber as much as possible, which is particularly suitable for objects with longer size, such as fishing rods, screwdrivers, document bags, umbrellas, etc. The design of the upper opening makes it easy to take and put, and is convenient to use. Compared with the existing bicycle basket, the objects are clamped between the two shielding members 5, and the possibility of the objects slipping and losing is greatly reduced, which is safer.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
