[0002] As living standards improve and the concept of healthy, green travel becomes more prevalent, electric-assisted bicycles are playing an increasingly important role in people's lives. Electric-assisted bicycles are mechatronic vehicles that utilize batteries as an auxiliary energy source, integrating components such as a motor, controller, battery, and display instrumentation. They offer advantages such as portability, environmental friendliness, and energy efficiency.

[0003] The existing bicycle frame mainly includes structures such as the front fork, front frame, and rear frame. Compared with ordinary bicycles, electric-assisted bicycles need to be additionally equipped with batteries on the frame. Therefore, battery holders need to be installed on the front frame, rear frame and other structures to place the batteries, which limits the shape of the electric-assisted bicycle frame. At the same time, due to the presence of the battery holder, the frame and the battery holder will become loose and a gap will be generated after long-term use, causing abnormal noise in the frame and affecting the driving quality of the electric-assisted bicycle. Summary of the Invention

[0004] In order to effectively improve the installation stability of the battery on the frame of an electric-assisted bicycle and at the same time improve the riding quality of existing electric-assisted bicycles, the present application provides a hidden battery structure for an electric-assisted bicycle and an installation method thereof.

[0005] The present application provides a hidden battery structure for an electric power-assisted bicycle using the following technical solutions:

[0006] A hidden battery structure for an electric-assisted bicycle includes a connecting portion, which is arranged on the inner side of a front frame and is used to place a battery; a positioning portion, which is arranged on the connecting portion and is used to limit the battery; and an adjusting portion, which is arranged on the front frame and can adjust the position of the connecting portion; the battery is slidably engaged with the inner side of the front frame.

[0007] By adopting the above technical solution, the connecting part can separate and protect the battery from the front frame while effectively improving the overall rigidity of the front frame, and the positioning part can stably place the battery on the connecting part, reducing the shaking of the battery when the electric-assisted bicycle is running. In addition, through the setting of the adjustment part, the bottom of the battery can be acted on to assist the positioning part to adapt to the position limitation of batteries of different models and sizes. Compared with the existing electric-assisted bicycles, the technical solution of the present application can stably place the battery on the inner side of the front frame, improve the space utilization rate, and better protect the battery, which is beneficial to improving the driving quality of the electric-assisted bicycle and has a greater promotion effect.

[0022] Optionally, the side wall of the front frame is provided with a strip hole that is snap-fitted with the cover plate.

[0023] By adopting the above technical solution, the cover plate is covered in the strip hole, and the strip hole is used to further limit the cover plate, thereby further improving the limiting stability of the cover plate on the battery.

[0024] On the other hand, the present application discloses a method for installing a hidden battery structure, comprising the following steps:

[0025] Step 1: Place the battery on the connector, and then place the connector inside the front frame;

[0043] The following is combined with Figure 1-8 This application is described in further detail.

[0044] Example 1

[0045] The first embodiment of the present application discloses a hidden battery structure for an electric power-assisted bicycle. Figure 1-3 The hidden battery 3 structure includes a connecting portion 1 and a positioning portion 4. The connecting portion 1 is integrally mounted inside the lower tube of the front frame 2, while the positioning portion 4 is mounted at the lower tube of the front frame 2, and the positioning portion 4 is movably connected to the connecting portion 1.

[0046] In this embodiment, the connecting portion 1 includes a bottom plate 11 and side plates 12. The bottom plate 11 is removably mounted within the front frame 2. Two side plates 12 are provided. Both side plates 12 have an arc-shaped cross-section and are symmetrically hinged on either side of the bottom plate 11 along its length. The positioning portion 4 is movably mounted between the two side plates 12. Furthermore, to facilitate quick installation of the battery 3, ridges 111 are provided on the edges of the top surface of the bottom plate 11.

[0047] Reference Figure 3-4 In this embodiment, the positioning portion 4 includes a clamping frame 41, sliding bars 42, and mounting blocks 43. Four sliding bars 42 are provided, and the four sliding bars 42 are symmetrically fixed to the two ends of the clamping frame 41 in the longitudinal direction in pairs. The mounting blocks 43 are correspondingly mounted at the bottom ends of the sliding bars 42. The clamping frame 41 as a whole is slidably connected to the two side panels 12 via the four sliding bars 42.

[0048] To facilitate movement of the clamping frame 41, a locking assembly 8 is provided at the top of the lower tube of the front frame 2. In this embodiment, the locking assembly 8 includes two first threaded strips 81, each threadedly extending through the top wall of the lower tube of the front frame 2. The bottom ends of the two first threaded strips 81 are rotatably connected to the two ends of the top of the clamping frame 41, respectively.

[0049] Reference Figure 3-4 To facilitate flexible adjustment of the two side panels 12 by the snap-on frame 41, a telescopic hole is defined at the end of the sliding bar 42 away from the snap-on frame 41. An insert bar 421 is slidably inserted into the telescopic hole. An elastic member 422 is installed within the telescopic hole, with its ends secured to the inner wall of the hole and one end of the insert bar 421, respectively. Furthermore, linkage slots 121 are defined through the side panels 12 at locations corresponding to the four sliding bars 42. These slots 121 have an arcuate cross-section, and the insert bar 421 is slidably connected to the slots 121 via a connecting ball 423 at its end.

[0050] When the battery 3 needs to be positioned and installed, the battery 3 is first placed on the bottom plate 11 and pre-positioned by the convex strips 111 on the bottom plate 11. Then, the bottom plate 11 and the battery 3 are placed as a whole into the lower tube of the front frame 2. Then, the position of the clamping frame 41 is adjusted by twisting the two first threaded strips 81, so that the clamping frame 41 further drives the side panels 12 on both sides of the bottom plate 11 to be retracted through the sliding strips 42 and the insertion strips 421, so as to achieve the purpose of limiting the position of the battery 3 placed on the bottom plate 11.

[0051] Reference Figure 2 and 5 To further enhance the stability of the battery 3 within the front frame 2, an adjustment portion 5 is provided at the bottom of the front frame 2. In this embodiment, the adjustment portion 5 comprises an extension bar 51 and a retaining block 52. The extension bar 51 is threadedly threaded through the bottom of the front frame 2, while the retaining block 52 is entirely located inside the front frame 2 and rotatably connected to the end of the extension bar 51 via a shaft. Furthermore, a through-hole adapted for the retaining block 52 is provided through the bottom plate 11, and the extension bar 51 extends through the front frame 2 and the through-hole.

[0052] When the battery 3 is entirely positioned on the bottom plate 11 by the snap-fit ​​frame 41, the tightening block 52 can be attached to the bottom of one side of the battery 3 by twisting the extension bar 51 to fine-tune the position of the battery 3. This allows the front frame 2 and the positioning portion 4 to cooperate to more effectively improve the installation stability of the battery 3 when the electric-assisted bicycle is in motion.

[0053] Reference Figure 2-3 To further improve the positioning and installation of the battery 3, a buffer assembly 6 is installed on the side of the two side panels 12 that are close to each other. In this embodiment, the buffer assembly 6 includes a flexible filling plate. The flexible filling plate is installed on the inner wall of the side panel 12 and is tightly abutted against the side wall of the battery 3. In this embodiment, the flexible filling plate can be a sponge block.

[0054] In addition, refer to Figure 3-5 To facilitate the removal and installation of the battery 3, a removal slot 122 is provided on the inner sidewalls of both side panels 12. The removal slot 122 is provided along the length of the side panels 12 and is located in the upper half of the inner sidewalls of the side panels 12 and in the curved area of ​​the side panels 12.

[0055] When the bottom plate 11 and the battery 3 need to be removed from the interior of the front frame 2 as a whole, the first threaded bar 81 can be turned to adjust the clamping frame 41 in a direction away from the battery 3 so that the connecting ball 423 slides into the disassembly groove 122, and then the extension bar 51 is turned to adjust the position of the clamping block 52. Finally, the bottom plate 11 and the battery 3 can be pulled out from the interior of the lower tube of the front frame 2 as a whole, thereby completing the quick disassembly of the battery 3.

[0056] Working principle: During installation, first place the battery 3 on the base plate 11 and pre-position it through the convex strips 111 on the base plate 11, then place the base plate 11 and the battery 3 as a whole into the lower tube of the front frame 2, then adjust the position of the clamping frame 41 by twisting the two first threaded strips 81, so that the clamping frame 41 further drives the side panels 12 on both sides of the base plate 11 to be retracted through the sliding strips 42 and the insertion strips 421, and quickly position the battery 3 on the base plate 11 through the buffer assembly 6 on the clamping frame 41 and the side panels 12, finally, by twisting the extension strip 51 at the bottom of the lower tube of the front frame 2, the tightening block 52 is driven to quickly contact and attach to the bottom of the battery 3, thereby improving the stability of the battery 3 during the travel of the electric-assisted bicycle, and effectively improving the travel quality of the electric-assisted bicycle.

[0057] In addition, the first embodiment of the present application also discloses a method for installing a hidden battery structure, comprising the following steps:

[0058] Step 1: Place the battery 3 on the bottom plate 11, then slide the bottom plate 11 and the battery 3 from the bottom end of the lower tube of the front frame 2 into the lower tube of the front frame 1 and place them inside the front frame 2;

[0059] Step 2: Twist the two first threaded bars 81 to adjust the position of the clamping frame 41 to limit the position of the battery 3;

[0060] Step 3: Twist the extension bar 51 to adjust the pressing block 52 to contact the bottom of the battery 3 to adjust the angular position of the battery 3 on the bottom plate 11, so that the battery 3, the front frame 2 and the card frame 41 are further pressed against each other to complete the installation of the hidden battery structure.

[0061] Example 2

[0062] Reference Figure 6-8 The difference between the second embodiment and the first embodiment is that, in this embodiment, the locking assembly 8 includes a lower pressing strip 82 and a second threaded strip 83. The lower pressing strip 82 is disposed inside the lower tube of the front frame 2 and is rotatably connected to the top of the clamping frame 41, while the second threaded strip 83 is threadedly penetrated through the top of the lower tube of the front frame 2. A protrusion 831 is fixed to one end of the lower tube of the front frame 2 through which the second threaded strip 83 penetrates. Furthermore, a groove is formed on the top surface of the lower pressing strip 82, and the protrusion 831 at the end of the second threaded strip 83 is rotatably connected to the groove formed on the lower pressing strip 82 via a rotating shaft 832.

[0063] In addition, in this embodiment, a strip-shaped hole is provided at the top of the lower tube of the front frame 2, into which the cover plate 7 is removably mounted. A lower pressing block 833 is also provided at the top of the lower pressing bar 82. The lower pressing bar 82 extends through the cover plate 7 and, through the lower pressing block 833, constrains the position of the cover plate 7. Furthermore, to facilitate adjustment of the placement angle of the battery 3, in this embodiment, the lower pressing bar 82 is curved on the side closest to the battery 3.

[0064] Working principle: When it is necessary to adjust the placement angle of the battery 3 inside the lower tube of the front frame 2, the extension bar 51 can be twisted to make the pressing block 52 lift the higher side of the battery 3, and make the top of the battery 3 close to one side of the lower pressing bar 82, thereby reducing the direct contact between the battery 3 and the lower tube of the front frame 2 and effectively improving the heat dissipation efficiency of the battery 3 during use, thereby further extending the service life of the battery 3.

[0065] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
