Description

Three-dimensional pattern manufacturing method and structure of bicycle frame transfer place

The invention relates to the field of application of a bicycle, in particular to a method for manufacturing a three-dimensional pattern of a bicycle frame transfer and a structure thereof.

Generally, at the adapter 310 of at least two tubes 320 of the bicycle frame 300, the adapter 400 is generally used in addition to the welding method (for example, the Republic of China invention patent No. I442988).

Referring to FIGS. 1 through 6, the illustration illustrates the engagement of each of the tubular bodies 320 of the conventional frame 300 with the adapter 400.

The adapters 400 can extend different shape patterns 410 to meet the needs of the customer.

However, since each of the frames 300 requires at least three adapters 400, the manufacturer of the bicycles is too costly for the number of adapters 400; further, the adapters 400 The shape pattern 410 can not be too complicated, and can not be represented by words. If the customer requires a complicated pattern, it must be handled manually, which also causes the cost to be too high, the yield is too low, and it is quite time consuming and cannot be Mass production.

The invention provides a method for manufacturing a three-dimensional pattern of a bicycle frame transfer position and a structure thereof, and the use of a mold and a filling material such as a foam material, at the transfer of the bicycle frame In order to directly form a desired three-dimensional pattern (including patterns and/or characters), and compared with conventional techniques, the manufacturing method used in the present invention can form a more complicated three-dimensional pattern, which can be avoided in manufacturing due to the structure. Too thin or too complicated to be destroyed, the manufacturing method of the creation is not only easy to manufacture, but also can be used to create complex patterns and/or characters in accordance with the needs of customers, and can be mass-produced and can improve production yield.

Therefore, the object of the present invention is to solve the above problems and provide a method for manufacturing a three-dimensional pattern of a bicycle frame transfer, the steps of which include: a mold clamping step: combining a mold in a frame and simultaneously connecting at least one of the two tubes At the transition, the model space includes a first shape space and a second shape space, the first shape space is a shape of the adapter of the frame, and the second shape space is formed outside the first shape space Surrounding and communicating with each other; filling and shaping step: injecting a filling material into the mold for filling, filling the filling material with the second shape space overflowing the model space, and allowing the filling material to be shaped into the second shape a three-dimensional pattern of the shape space; and a demolding step: detaching the mold from the adapter of the frame.

In some embodiments, the three-dimensional pattern of the second shape space includes a pattern and/or a text.

In some embodiments, the transition includes at least two tubes connected at the same time.

In some embodiments, the text includes Chinese characters and/or foreign text.

In certain embodiments, the filler material includes at least a foamed material, a plastic material, a resin material, and a metal material.

The present invention further provides a three-dimensional pattern structure of a bicycle frame transfer, which is manufactured by the above manufacturing method. The bicycle frame transfer portion is simultaneously connected with at least two tubes of a frame, and the three-dimensional pattern structure further includes a pattern and / or a text.

The above objects and advantages of the present invention will be readily understood from the following detailed description of the embodiments of the invention.

Referring to Figures 7 to 13, the method for manufacturing a three-dimensional pattern of the bicycle frame transfer of the present invention can be as shown in Figures 7 to 13, and the steps thereof are as follows.

The mold clamping step S1 is: combining a mold 200 in a frame 100 at least simultaneously connecting a transition portion 110 of the two tubular bodies 120. A mold space 210 is formed inside the mold 200, and the model space 210 includes a first shape space 211 and A second shape space 212, the first shape space 211 is in the shape of the adapter 110 of the frame 100, and the second shape space 212 is formed around the outer side of the first shape space 211 and communicates with each other.

Filling and shaping step S2: injecting a filling material into the mold 200 for filling The filling material fills the second shape space 212 of the model space 210 and is allowed to stand until the filling material is shaped into one of the second shape spaces 212.

Demolding step S3: The mold 200 is detached from the adapter 110 of the frame 100.

The three-dimensional pattern 220 of the second shape space 212 in the above steps may include a graphic and/or a character, and the characters include Chinese characters and/or foreign characters.

In addition, the filling material includes at least a foaming material, a plastic material, a resin material, a metal material, and the like.

According to the above method and structure, in the use of a mold and a filling material such as a foaming material, a desired three-dimensional pattern (including a pattern and/or a character) is directly formed at the transfer portion of the bicycle frame, and Compared with the prior art, the manufacturing method used in the present invention can form a more complicated shape body, such as the three-dimensional jet flame pattern shown in Fig. 12, which can be prevented from being destroyed due to too small or too complicated structure during manufacture. In this way, the manufacturing method of the creation is not only easy to manufacture, but also can be used to manufacture complex patterns and/or characters in accordance with the needs of the customers, and can be mass-produced, and the production yield can be improved.

The disclosure of the above-described embodiments is intended to be illustrative of the present invention and is not intended to limit the present invention, and variations of the numerical values or substitutions of equivalent elements are still within the scope of the present invention.
