Description

Technical Field

[0001] This utility model belongs to the field of bicycles, and in particular relates to an internal positioning structure for a bicycle and a bicycle. Background Technology

[0002] Existing bicycles typically house batteries or toolboxes within the tubes. During assembly, for example, when assembling a battery, it is inserted from the bottom opening of the motor towards the head tube, and then slowly moved until it aligns with the mounting holes of the positioning structure inside the tube. However, this presents the following problems:

[0003] 1. Slow assembly efficiency: During assembly, the screw holes on the battery cannot be aligned with the positioning holes of the lower tube in one go. They need to be moved slowly to align, which consumes a lot of time.

[0004] 2. Difficult to operate: When assembling, one hand holds the frame and the other holds the battery. Since the battery needs to be completely inserted into the bottom tube of the frame, it is inconvenient to hold the battery. After a long time, the hand will be sore, and the operator cannot work for a long time. Summary of the Invention

[0005] The purpose of this utility model is to provide an in-tube positioning structure for bicycles and a bicycle in general, so as to solve the problems of long time and laborious operation when assembling batteries and waiting for installation parts in the prior art.

[0023] To explain the technical content, structural features, and effects of the utility model in detail, the following describes the embodiments in combination with the drawings.

[0024] like Figures 1 to 6 As shown, this utility model embodiment provides a tube positioning structure for a bicycle, including a hollow tube 11 and a limiting boss 12 provided on the inner wall of the hollow tube 11. The hollow tube 11 has a first end 111 and a second end 112 opposite to the first end 111. The hollow tube 11 is provided with at least two mounting holes for installing a component 2 to be installed. The at least two mounting holes extend from the outer surface of the hollow tube 11 through the hollow tube 11 to the interior of the hollow tube 11. The at least two mounting holes include a first hole 113 near the first end 111 and a second hole 114 near the second end 112. The limiting boss 12 is provided on the side of the second hole 114 near the second end 112. The limiting boss 12 is provided corresponding to the component 2 to be installed, and when the limiting boss 12 abuts against the front end of the component 2 to be installed, the at least two mounting holes are aligned with the corresponding connecting holes 211 on the component 2 to be installed. Specifically, the component to be installed is a battery or toolbox, and the hollow tube 11 corresponds to the downtube of a bicycle. The first end 111 is an open structure for connecting to the motor cavity, and the second end 112 is for connecting to the head tube. There are two mounting holes. Both ends of the component to be installed 2 in the length direction are provided with outwardly protruding connecting portions 21, and the connecting portions 21 are provided with connecting holes 211. When the component to be installed 2 is a battery, specifically a lithium battery, when assembling the bicycle, the component to be installed 2 is inserted from the first end 111 and pushed along the inner wall of the hollow tube 11 until it reaches the connecting portion 211 at the front end of the component to be installed 2. When the tool box is a toolbox, an installation slot can be opened at a suitable position on the hollow tube 1. Push the toolbox into the installation slot and push the toolbox along the inner wall of the hollow tube 11 until the connecting part 21 at the front end of the tool box reaches the limit boss 12. At this time, the two mounting holes and the two connecting holes 211 are aligned. Connect the mounting holes and the connecting holes 211 to complete the installation of the toolbox.

[0025] In this embodiment of the utility model, a limiting boss 12 is added inside the hollow tube body 11 to restrict the movement space of the component 2 to be installed. When the component 2 to be installed reaches the limiting boss 12, the mounting hole automatically aligns with the connecting hole 211, which effectively saves time and reduces workload. The design is ingenious.

[0026] In this embodiment of the utility model, such as Figure 2 and Figure 3As shown, the limiting boss 12 includes a first side surface 121 near the second hole 114 and a second side surface 122 opposite to the first side surface 121. The first side surface 121 is a first inclined surface, and the second side surface 122 is a second inclined surface. The angle between the first side surface 121 and the horizontal plane is greater than the angle between the second side surface 122 and the horizontal plane. Specifically, the first side surface 121 is used to abut against the front end of the part 2 to be installed. The angle between the first side surface 121 and the horizontal plane is greater than or equal to 75 degrees and less than or equal to 90 degrees, which ensures a better abutment effect between the first side surface 121 and the front end of the part 2 to be installed, and also ensures the overall structural strength of the limiting boss 12. The design is ingenious.

[0027] In this embodiment of the utility model, such as Figure 3 As shown, the first side 121 and the second side 122 are also connected by a connecting transition surface 123. Specifically, the connecting transition surface 123 is an arc surface, and the first side 121 and the second side 122 are connected by the connecting transition surface 123, which is easy to manufacture and has high structural strength.

[0028] In this embodiment of the utility model, such as Figure 4 As shown, the two ends of the limiting boss 12 abut against the inner wall of the hollow tube 11. Specifically, the two ends of the limiting boss 12 are set to correspond to the inner wall structure of the hollow tube 11 and are connected to the inner wall of the hollow tube 11, which effectively ensures the stability of the limiting boss 12 structure.

[0029] In this embodiment of the invention, both the hollow tube body 11 and the limiting boss 12 are made of carbon fiber. Specifically, the internal positioning structure made of carbon fiber has the advantages of high strength, good rigidity, impact resistance, fatigue resistance, and corrosion resistance.

[0030] In this embodiment of the invention, the hollow tube 11 and the limiting boss 12 are integrally formed. Specifically, when manufacturing the hollow tube 11 with the limiting boss 12, a groove for forming the limiting boss 12 can be pre-set on the mandrel, and then carbon fiber gauze can be attached to the mandrel and the groove, thereby integrally forming the hollow tube 11 and the limiting boss 12, resulting in better structural strength.

[0031] In this embodiment of the utility model, such as Figure 5 as well as Figure 6 As shown, the mounting hole and the connecting hole 211 are connected by bolts 3. Specifically, the mounting hole is a threaded through hole, and the connecting hole 211 is a threaded blind hole. The mounting hole and the connecting hole 211 are connected by bolts 3, which is convenient and does not require changing the original structure of the mounting hole and the connecting hole 211.

[0032] This embodiment of the invention also provides a bicycle, including the aforementioned internal positioning structure and a component 2 to be installed. The component 2 is installed inside the hollow tube 11 and connected to the hollow tube 11. Specifically, this embodiment adds a limiting boss 12 inside the hollow tube 11 of the internal positioning structure to restrict the movement space of the component 2. When the component 2 reaches the limiting boss 12, the mounting hole automatically aligns with the connecting hole 211, effectively saving time and reducing workload, making bicycle assembly faster.

[0033] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
