Description

Technical Field

[0001] The utility model relates to a battery installation structure for an electric power-assisted bicycle, and more particularly to an inner-liner type battery box. Background Art

[0002] At present, for electric-assisted bicycles, the battery boxes are basically placed inside the frame, and the battery boxes are used in sets with the downtube of the frame. This downtube usually has a long notch milled out for placing the battery box, so the cross-section of the downtube of the frame also determines the installation size of the battery box. In order to fix the battery box inside the downtube of the frame, a set of mounting bases are usually provided at both ends of the battery box, namely an upper base and a lower base. The upper and lower bases are generally used as a separate integral shape, and like the battery box, their shape structure must be consistent with the cross-section of the downtube of the frame. One of the bases will fix a set of lock cores. When installing, first fix the lock core on one of the bases, and then fix the two bases inside the downtube of the frame according to the placement direction of the battery box. Then place the battery box in, the lock core will automatically lock, and the installation is completed.

[0003] Existing traditional battery boxes and base kits are all matched with a single frame down tube, and the tube material and shape are relatively simple. If you want to replace the frame down tube with a different shape, you must redevelop a new battery box and matching base, and the shape will be limited by the cross-section of the frame down tube. When multiple frame down tubes are required, the development cost is relatively high. Utility Model Content

[0004] In order to solve the above technical problems, the purpose of the present utility model is to provide an inner liner type battery box, which is flexible to install and can match frame tubes of different sizes.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0030] like Figures 1 to 6The illustrated embodiment of an internal liner battery pack includes a frame tube 1 and a battery pack 3 mounted therein. The frame tube 1 is provided with a mounting slot. A first base assembly 12 and a second base assembly 14 are secured to the lower portions of the mounting slot. The battery pack 3 has two ends that snap or plug into the first and second base assemblies 12, 14, respectively, and is electrically connected to the first and / or second base assemblies 12, 14. A cover locking assembly 11 and a retaining assembly 13 are secured to the upper portions of the mounting slot. A cover assembly 2 is provided above the battery pack 3. The two ends of the cover assembly 2 snap or plug into the cover locking assembly 11 and the retaining assembly 13, respectively. The cover assembly 2 includes a battery cover 22 and a rubber sleeve 21 surrounding the battery cover 22. The rubber sleeve 21 enhances the seal between the frame tube and the battery cover, protecting the internal battery pack from external influences such as dust and moisture.

[0031] The utility model forms a battery box into an inner tank structure by making the original upper and lower bases into separate structures, and can be installed in multiple sets of frame tubes of different shapes, thereby reducing development costs. At the same time, under the premise of ensuring installation space, the frame tube shapes can be rich and diverse.

[0032] The first base assembly 12 includes a limiting frame A122 and a support block A123. The limiting frame A122 is fixed to the frame tube 1, and the support block A123 is fixed to the limiting frame A122. A lock core 121 is fixed on the support block A123. A through hole is provided at one end of the battery box 3, and the lock core 121 is inserted into the through hole.

[0033] The second base assembly 14 includes a limit frame B141 and a support block B142. The limit frame B141 is fixed to the frame tube 1, and the support block B142 is fixed to the limit frame B141. An electrical connector B143 is fixed to the support block B142. Positioning recesses 144 are provided on both sides of the electrical connector 143. An electrical connector A is provided at the other end of the battery box 3. Positioning protrusions 31 are provided on both sides of the electrical connector A. The positioning protrusions 31 are clamped in the positioning recesses 144, and the electrical connector A and the electrical connector B143 are plugged and connected.

[0034] The cover locking assembly 11 includes a fixed bracket 111, a dial knob 112 and a locking block 113. The locking block 113 is inserted into the fixed bracket 111, and a spring is provided between the locking block 113 and the fixed bracket 111. The dial knob 112 is slidably provided on the frame tube 1, and the lower end is connected to the locking block 113. A slot block 222 is fixed to one end of the cover assembly 2, and the locking block 113 is inserted into the slot block 222 under the action of the spring.

[0035] A limiting groove A131 and a limiting groove B132 are arranged in parallel on the limiting assembly 13, an insert 221 is fixed to the other end of the cover assembly 2, and an insert block is also provided at the other end of the battery box 3. The insert block and the insert 221 are respectively inserted into the limiting groove A131 and the limiting groove B132.

[0036] A wiring harness cover 15 is provided between the frame tube 1 and the battery box 3, forming a wiring harness through hole between the wiring harness cover 15 and the frame tube 1. Two positioning ribs are spaced apart on the lower end surface of the wiring harness cover 15, and the frame tube 1 is provided with a notch, in which the positioning ribs are locked.

[0037] The utility model forms an inner tank structure of the battery box by making the original upper and lower bases into separate structures. The cover plate and the battery body are separate structures. While ensuring that there is sufficient space inside the tube material, the embedded battery can be better adapted to lower tubes of different shapes, and at the same time, the length of the battery box shell profile can be appropriately adjusted to change the battery capacity.

[0038] The utility model combines a split base with a battery box installed in an inner tank style, so that a battery box can match frame tubes of different shapes. While ensuring sufficient installation space, the frame tube shapes can be rich and diverse, which not only satisfies the overall shape matching of the frame tube and the frame, but also reduces unnecessary development costs of the battery box and base, thereby greatly controlling costs for users of this battery box.
