Description

Technical Field

[0001] The invention relates to a frame tube, in particular to a multi-purpose quick-release self-locking battery pack and frame connection mechanism. Background Art

[0002] Currently, lithium battery-assisted bicycles are becoming increasingly popular. There are various forms of lithium battery installation. Among them, frame tube-hidden batteries are widely favored by users for their neat appearance, easy disassembly and assembly, safety and reliability.

[0003] At present, tube-hidden batteries often adopt the form of installing the battery pack after the frame tube is cut as a whole. After the user removes the battery, a large area of ​​the cutout position will be exposed at the original position of the frame, which not only affects the appearance, but also causes the internal electrical components and wiring harnesses to be directly exposed to the outside, making it easy for foreign dust, rainwater and other debris to enter the battery installation compartment, which can easily lead to aging of the wiring harness and the inability to properly disassemble and assemble the battery, affecting the service life of the entire vehicle. The improvement scheme proposed in the prior art is to install a dustproof plate on the cutout. In this improvement scheme, the dustproof plate and the battery pack are installed separately, there is no anti-theft measure, and it is easy to lose. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a multi-purpose quick-release self-locking battery pack and frame connection mechanism. The electric power-assisted bicycle using the frame tube has a longer service life, and the dustproof plate and the battery pack are not easy to be lost.

[0005] In order to solve the above problems, the following technical solutions are provided:

[0006] The multi-purpose quick-release self-locking battery pack and vehicle frame connection mechanism of the present invention comprises a tube body and a battery pack. The tube body is provided with a cutout that matches the battery pack, and the battery pack is installed in the section of the tube body corresponding to the cutout through the cutout. It is characterized in that a dust cover is provided on the cutout, and the two long sides of the dust cover are provided with guide flanges bent inward, and both sides of the outer wall of the battery pack are provided with guide bosses arranged along the longitudinal direction thereof, and the guide flanges and the guide bosses are arranged in a one-to-one correspondence, so that the battery pack can be loaded into the dust cover from the bottom end of the dust cover along the guide flange through the guide boss. A limit plate is provided on the inner side of one end of the dust cover, and the limit plate is provided with a lock port, and a lock matched with the lock port is provided in the tube body.

[0007] Among them, one end of the dust cover is provided with a limit plate extending downward, and one end of the battery pack is provided with an elastic locking tooth extending axially outward. When the battery pack is fully loaded into the dust cover, the elastic locking tooth clamps the limit plate, so that the battery pack is fixed in the dust cover.

[0008] A baffle is fixed in the inner cavity of the tube body corresponding to the limiting plate, and a positioning boss extending axially outward is provided at one end of the dust cover plate away from the limiting plate. A limiting groove is provided on the cut end surface corresponding to the positioning boss, so that the battery pack can be installed in the tube body corresponding to the cut.

[0009] The baffle plate is provided with a guide hole, and the lock comprises a lock tongue located in the guide hole, the front end of the lock tongue is located on the baffle side corresponding to the battery pack, and the rear end is located on the baffle side away from the battery pack, the lock tongue and the guide hole are slidingly matched, and a pit is provided on the limit plate corresponding to the front end of the lock tongue, and the pit is the lock port, and a lock core for driving the lock tongue to enter and exit the lock port is provided in the tube body corresponding to the rear end of the lock tongue, and a clearance hole is provided on the side wall of the tube body corresponding to the keyhole end of the lock core, and the keyhole end of the lock core is located in the clearance hole.

[0010] The lower surface of the limit plate corresponding to the elastic locking teeth is in an inclined shape, and the two are in a snap-fitting fit when installed.

[0011] The side surface of the limiting plate is provided with reinforcing ribs.

[0012] The above solution has the following advantages:

[0013] Since the two long sides of the dust cover of the multi-purpose quick-release self-locking battery pack and the frame connection mechanism of the present invention are provided with inwardly bent guide flanges, both sides of the outer wall of the battery pack are provided with guide bosses arranged along the longitudinal direction thereof, the guide flanges and the guide bosses are arranged in a one-to-one correspondence, the dust cover is provided with a lock, and the tube body has a lock adapted to the lock. This frame tube uses the dust cover to protect the inner cavity of the frame tube after the battery pack is removed, so that the section of the frame tube where the battery pack is located will not expose a large area of ​​the cut position, and the aesthetics are good, and the electrical components and wiring harnesses in the frame will not be directly exposed to the outside, so that external dust, rainwater and other debris will not enter the inner wall of the frame tube, and the situation of external dust and rainwater aging the electrical components and wiring harnesses in the frame is avoided, ensuring that the battery pack can be disassembled and assembled normally, and the service life of the whole vehicle is long. Moreover, the battery pack and the dust cover of the frame tube are detachably connected together through the guide boss and the guide flange, and the dust cover is locked by the lock, so that the battery pack and the dust cover are not easily lost. At the same time, after the battery pack is removed, the lock can still lock the dust cover alone. Even if the dust cover is installed in the cutout after the battery pack is removed, the lock can still be used to lock the dust cover, ensuring that the dust cover is not easily lost after the battery pack is removed.
