Description

Technical Field

[0001] The utility model relates to the technical field of electric bicycle frames, and particularly relates to a modular electric bicycle frame. Background Technique

[0002] In recent years, with the continuous development of new energy technologies, the practicality of electric bicycles has been gradually enhanced. In the usage scenarios of urban commuting, electric bicycles have the advantages of being light, flexible, low in usage cost, green and environmentally friendly, and less restricted by urban traffic conditions. Therefore, electric bicycles have gradually become one of the main travel tools selected by office workers;

[0003] Most of the existing electric bicycle frames are non-foldable and of an integral structure, resulting in a large occupied space when transporting them, which is not convenient for people to make full use of the space, and thus not convenient for people to transport and carry the bicycle frames. For this reason, we propose a modular electric bicycle frame. Content of the Utility Model

[0004] The purpose of the utility model is to provide a modular electric bicycle frame, which solves the problems in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A modular electric bicycle frame includes a main pipe, a front frame, a rear frame, a branch pipe and a support pipe. The support pipe is fixedly installed at the bottom end of the main pipe, and the telescopic branch pipe is inserted into the top end of the main pipe. At one end above the front frame and the rear frame, a first mounting plate is fixedly installed respectively. At one end below the front frame and the rear frame, a second mounting plate is fixedly installed respectively. An assembly mechanism one and an assembly mechanism two are respectively arranged between the first mounting plate and the main pipe and between the second mounting plate and the support pipe;

[0006] The assembly mechanism one includes a mounting block. An installation opening is formed on the outer wall of the main pipe. The mounting block is inserted into the installation opening. A fixing hole is formed on the mounting block. A vertical groove is formed at the bottom end of the branch pipe. The branch pipe passes through the fixing hole through the vertical groove movably;

[0007] The assembly mechanism two includes a positioning block, a clamping plate and a fastening bolt. The positioning block is fixedly installed on the outer wall of the support pipe.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0025] As Figures 1-5 shown, the present utility model provides a technical solution: a modular electric bicycle frame, including a main pipe 1, a front frame 2, a rear frame 3, a branch pipe 4 and a support pipe 8. The support pipe 8 is fixedly installed at the bottom end of the main pipe 1, the telescopic branch pipe 4 is inserted into the top end of the main pipe 1, one end above the front frame 2 and the rear frame 3 is fixedly installed with a first mounting plate 5, one end below the front frame 2 and the rear frame 3 is fixedly installed with a second mounting plate 6, and a first assembly mechanism 7 and a second assembly mechanism 9 are provided between the first mounting plate 5 and the second mounting plate 6 and the main pipe 1 and the support pipe 8 respectively;

[0026] The first assembly mechanism 7 includes a mounting block 701. An installation opening 703 is formed on the outer wall of the main pipe 1. The mounting block 701 is inserted into the installation opening 703. A fixing hole 702 is formed on the mounting block 701. A vertical groove 704 is formed at the bottom end of the branch pipe 4. The branch pipe 4 movably penetrates through the fixing hole 702 through the vertical groove 704.

[0027] The second assembly mechanism 9 includes a positioning block 901, a clamping plate 903 and a fastening bolt 905. The positioning block 901 is fixedly installed on the outer wall of the support pipe 8. A positioning opening 902 is formed on the second mounting plate 6. The positioning block 901 movably penetrates through the second mounting plate 6 through the positioning opening 902. A clamping groove 904 is formed at the top end of the positioning block 901. The clamping plate 903 is clamped in the clamping groove 904. The clamping plate 903 is fixedly connected to the second mounting plate 6 through the fastening bolt 905.

[0028] Specifically, in the above technical solution, when it is necessary to transport the bicycle frame, the branch pipe 4 can be pulled out upward, so that the branch pipe 4 is separated from the main pipe 1, the branch pipe 4 is separated from the fixing hole 702, and the branch pipe 4 no longer limits the mounting block 701. Then, turn the fastening bolt 905 to make the fastening bolt 905 separate from the second mounting plate 6. At this time, the clamping plate 903 can be lifted upward to make the clamping plate 903 separate from the clamping groove 904, so that the clamping plate 903 no longer limits the second mounting plate 6. At this time, pull the front frame 2 or the rear frame 3 outward, and the mounting block 701 can be driven to separate from the installation opening 703, and the second mounting plate 6 can be driven to separate from the positioning block 901, thereby completing the disassembly of the front frame 2 and the rear frame 3. Through the above structure, it is convenient for personnel to disassemble the bicycle frame, reduce the occupied space, and facilitate personnel to transport it, solving the problem that most existing bicycle frames are not foldable and are of an integral structure, resulting in a large occupied space when personnel transport them, which is not convenient for personnel to make full use of space, and thus not convenient for personnel to transport and carry the bicycle frame.

[0029] Furthermore, the mounting block 701 is adapted to the installation opening 703, and the number of the vertical grooves 704 is four.

[0030] Among them, by providing the vertical groove 704, the branch pipe 4 can be inserted into the fixing hole 702 through the vertical groove 704, thereby limiting the mounting block 701.

[0031] Furthermore, the clamping plate 903 is adapted to the clamping groove 904, and the positioning block 901 is adapted to the positioning opening 902.

[0032] Among them, by providing the clamping plate 903, the clamping plate 903 can be inserted into the clamping groove 904, thereby limiting and fixing the second mounting plate 6.

[0033] Furthermore, the number of the fastening bolts 905 on the clamping plate 903 is two.

[0034] Furthermore, a reinforcing plate 10 is fixedly installed on the inner wall of the branch pipe 4, and the plate of the branch pipe 4 between the two vertical grooves 704 is adapted to the fixing holes 702;

[0035] Among them, by setting the reinforcing plate 10, a certain supporting and reinforcing effect can be achieved on the branch pipe 4, thereby improving the strength of the branch pipe 4 during use.

[0036] Furthermore, the material of the reinforcing plate 10 is stainless steel.
