Description

Technical Field

[0001] This utility model relates to the field of bicycle structural technology, and in particular to a battery mounting structure inside a bicycle frame. Background Technology

[0002] The bottom bracket, also known as the bottom bracket, is a crucial component connecting the front and rear wheels of a bicycle. Located in the center of the frame, it serves to secure and support the pedal cranks and chainring. A battery is typically installed in the bottom bracket area to power the front and rear derailleurs, enabling electronic shifting.

[0003] The existing battery mounting structure within the vehicle frame includes a seatpost and a flexible flare sleeve. The seatpost has an inner bore, and the flare sleeve is divided into a large-diameter section and a small-diameter section. A retaining flange is provided on the inner wall of the small-diameter section, and a corresponding annular groove is formed on the outer surface of the battery. The battery is inserted into the flare sleeve, causing the retaining flange to engage with the annular groove. The flare sleeve is then inserted into the inner bore of the seatpost, causing the large-diameter section of the flare sleeve to abut against the inner wall of the seatpost's inner bore. The weight of the battery is converted into frictional force between the large-diameter section of the flare sleeve and the inner wall of the seatpost.

[0004] In the existing battery mounting structure, the battery inside the horn sleeve is kept in a fixed position with the seat post by the friction between the large-diameter part of the horn sleeve and the inner wall of the seat post. However, this battery mounting structure has the disadvantage of being inconvenient to disassemble when the battery needs to be replaced, and this needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide a battery mounting structure inside the vehicle frame that is easy to disassemble and replace.

[0006] This utility model proposes a battery mounting structure in a vehicle frame, including a base, a fixing plate and a fixing ring. The fixing plate is located on the base, and a mounting groove is formed on the surface of the fixing plate. One side of the battery is inserted into the mounting groove and fits against the inner side wall of the mounting groove.

[0007] The retaining ring is fitted around the battery and the retaining plate, and the base is locked to the frame wall.

[0008] Preferably, a first fixing groove is formed on the outer surface of the battery, a second fixing groove is formed on the outer surface of the fixing plate, and the fixing ring is embedded in the first fixing groove and the second fixing groove.

[0009] Preferably, the battery is cylindrical, the fixing plate is an arc-shaped plate, the mounting groove is an arc-shaped groove, and the battery and the mounting groove are fitted together by a transition fit.

[0010] Preferably, the arc of the arc plate is set to α, and satisfies 0.6π < α < π.

[0011] Preferably, the bottom end of the fixing plate is provided with a baffle portion, the baffle portion and the fixing plate are mutually enclosed to form a ring, the fixing plate, the baffle portion and the base are integrally injection molded, and an end groove is formed between the baffle portion, the fixing plate and the base, and one end of the battery is inserted into the end groove.

[0012] Preferably, the fixing plate, the enclosure, and the base are all made of carbon fiber material.

[0013] Preferably, the retaining ring is made of rubber material.

[0014] Preferably, the surface of the base has a through-hole for forming a mounting hole, and a mounting bolt passes through the mounting hole and is threadedly connected and fixed to the bottom bracket of the frame.

[0030] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer and more understandable, the following description is provided in conjunction with the appendix. Figure 1-8 The present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0031] Reference Figure 1 and Figure 2 A battery mounting structure for a vehicle frame is disclosed. The entire battery mounting structure is installed at the bottom bracket position of the frame. The battery mounting structure includes a base 1, a fixing plate 2, and a pair of fixing rings 3. The fixing plate 2 is integrally mounted on the base 1, and a mounting groove 21 is formed on one side surface of the fixing plate 2. The battery 4 to be mounted is cylindrical, so the fixing plate 2 is set as an arc-shaped plate, making the mounting groove 21 on one side surface of the fixing plate 2 an arc-shaped groove, so that the arc-shaped groove can transition and fit with the cylindrical battery 4.

[0032] The bottom end of the battery 4 abuts against the surface of the base 1, and one side of the battery 4 is inserted into the mounting groove 21 of the fixing plate 2, so that the outer surface of the battery 4 abuts against the inner wall of the mounting groove 21. To facilitate the installation of the battery 4 from one side of the fixing plate 2 into the mounting groove 21, the curvature of the arc plate is set to α, and the curvature of the arc plate satisfies 0.6π < α < π. This avoids the arc size of the arc plate being too large, which would prevent the battery 4 from being inserted into the mounting groove 21 from one side of the fixing plate 2; or the arc size of the arc plate being too small, which would make it difficult to fix the battery 4 firmly to the arc plate.

[0033] Reference Figure 3 , Figure 4 and Figure 5 In order to fix the battery 4 to the fixing plate 2, two first fixing grooves 41 are formed on the outer surface of the battery 4, and correspondingly two second fixing grooves 22 are formed on the outer surface of the fixing plate 2. The two second fixing grooves 22 are respectively located at the top and bottom of the outer surface of the fixing plate 2, and the spacing between the two second fixing grooves 22 is equal to the spacing between the two first fixing grooves 41.

[0034] Two retaining rings 3 are fitted around the battery 4 and the fixing plate 2, and are thus secured to the battery 4 and the fixing plate 2 by fitting the retaining rings 3 into the first fixing groove 41 and the second fixing groove 22. The retaining rings 3 are made of rubber. Because rubber has good elasticity and compressive deformation capacity, the retaining rings 3, after being fitted into the first fixing groove 41 and the second fixing groove 22, can remain in close contact with the inner walls of the two grooves. Furthermore, the retaining rings 3 made of rubber are easy to process and install. Rubber retaining rings 3 are usually manufactured using compression molding or injection molding processes, which generally results in lower costs and helps reduce production costs.

[0035] Reference Figure 2 and Figure 5To further ensure a secure connection between the battery 4 and the mounting plate 2, a retaining portion 23 is formed at the bottom of the mounting plate 2. The retaining portion 23 is also located on the base 1, and it and the mounting plate 2 enclose each other to form a ring. The mounting plate 2, retaining portion 23, and base 1 are integrally injection molded from carbon fiber material, forming an end groove 24. When installing the battery 4, it slides down along the inner wall of the mounting groove 21 of the mounting plate 2, causing one end of the battery 4 to be inserted into the end groove 24. The end groove 24 further secures the battery 4. The use of carbon fiber material for the mounting plate 2, retaining portion 23, and base 1 gives them extremely high structural strength while maintaining overall lightweight construction, resulting in a lighter bicycle frame.

[0036] Reference Figure 6 , Figure 7 and Figure 8 To ensure a secure connection between the battery mounting structure and the bicycle frame bottom bracket 5, several mounting holes 11 are formed through the base 1, and a receiving groove 12 is formed on the surface of the base 1, with the mounting holes 11 located within the receiving groove 12. Mounting bolts 13 are inserted into the mounting holes 11. A slot 51 for mounting the battery mounting structure is formed in the frame bottom bracket 5. During installation, the battery mounting structure is inserted into the slot 51 of the frame bottom bracket 5 and secured. After the mounting structure containing the battery 4 is inserted into the frame bottom bracket 5, the mounting bolts 13 inserted into the mounting holes 11 are threadedly connected and secured to the frame bottom bracket 5, with the heads of the mounting bolts 13 embedded and hidden within the receiving groove 12. This prevents the heads of the mounting bolts 13 from being exposed outside the base 1, resulting in a more aesthetically pleasing appearance.

[0037] The specific implementation principle of this application embodiment is as follows: When it is necessary to install the battery 4 at the bottom bracket 5 of the vehicle frame, the battery 4 is inserted into the mounting groove 21 from one side of the fixing plate 2. The battery 4 slides along the inner side wall of the mounting groove 21, thereby causing the end of the battery 4 to be inserted into the end groove 24. Then, the fixing ring 3 is sleeved on the periphery of the battery 4 and the fixing plate 2. The fixing ring 3 slides along the outer surface of the battery 4 and the fixing plate 2, and is inserted into the first fixing groove 41 and the second fixing groove 22, thereby firmly fixing the battery 4 to the fixing plate 2. The fixing ring 3, made of rubber material, not only fixes the battery 4 to the fixing plate 2 firmly, but also has the advantage of easy disassembly.

[0038] After the battery 4 is securely fixed to the mounting structure, the battery mounting structure is inserted into the slot 51 of the frame bottom bracket 5, and a mounting bolt 13 is inserted into the mounting hole 11 of the base 1. Once the surface of the base 1 is flush with the surface of the frame bottom bracket 5, the mounting bolt 13 is threadedly connected to the inside of the frame bottom bracket 5, thus securing the battery mounting structure firmly to the frame bottom bracket 5. After installation, the head of the mounting bolt 13 is concealed within the receiving groove 12 of the base 1, resulting in a more aesthetically pleasing appearance.

[0039] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, shall be protected by the present invention.
