Battery pack mounting structure for electric bicycle

This creation relates to an electric bicycle, and more particularly to the creation of a battery pack for an electric bicycle.

In recent years, riding bicycles (or bicycles, bicycles) is currently the most popular leisure sport. People like to ride a bicycle or go on a bicycle in their leisure time or on consecutive holidays. With the rapid development of bicycle manufacturing technology, electric bicycles (or electric bicycles) have gradually become popular. Since the electric motor is integrated into the bicycle, the electric bicycle can convert the power into the power to propel the car forward. In addition, electric bicycles use batteries as their main energy source, and their appearance is similar to that of a conventional bicycle or motorcycle, and is a type of motorized bicycle. Some electric bicycles also have pedals and chains that can be used as auxiliary power.

In general, electric bicycles use lead-acid batteries as their main energy source, and usually two to four 12V lead-acid batteries or four to eight 6V lead-acid batteries are connected in series to form a battery pack. In recent years, many electric bicycle manufacturers have developed electric bicycles using lithium batteries as their main energy source. The battery pack is typically placed in a battery box or battery holder, and in general the battery pack is assembled to the frame of the electric bicycle via a mechanical mounting structure.

Regarding the battery pack mounting structure of an electric bicycle, several patents have been published. For example, the Republic of China new patent M312492 discloses a battery mounting structure for an electric assist bicycle, which is mounted on an electric assist bicycle rear fork tube, which comprises: a carrier mounted at a predetermined position of the rear fork tube, the carrier The top cover has a receiving portion, and a receiving groove is formed in the bottom surface of the carrying portion, and an accommodating space is formed therein; a battery case is installed in the receiving groove of the carrying frame, and a battery pack is arranged therein; A support rod is disposed on each side of the bottom surface of the groove, and the bottom ends of the two support rods are respectively connected to a connecting piece fixed to the rear fork tube. The two fixing members provide the fixing effect of the carrier, and the two supporting rods and the two connecting pieces provide the supporting effect of the carrier. However, the battery mounting structure taught in this patent must additionally provide a carrier attached to the rear fork tube to accommodate the battery pack using the receiving groove on the top surface of the carrier. Thus, the battery mounting structure taught by this patent adds additional manufacturing costs and results in an increase in the size and weight of the bicycle.

The Chinese utility model patent CN203780709U discloses a fixed structure of an electric bicycle battery pack. The electric bicycle battery pack fixing structure disclosed in the patent comprises a frame tube, a lock and a card holder, and the frame tube is provided with a slit groove, and one side of the slit groove width direction is hollowed out, and the other side leaves the frame tube wall. thick. The lock and the card holder are respectively fixed at two ends of the slit slot in the longitudinal direction, and the battery pack is detachably fixed between the lock and the card holder. By leaving the wall thickness of the frame tube on the other side of the cross section of the slit groove in the frame tube, the strength of the frame tube at the notch groove is increased, and the frame tube is effectively prevented from being deformed or broken. In addition, the battery pack is installed in the slit groove by the lock and the card holder, so that the vehicle structure is more compact and beautiful. One side of the slit groove width direction is hollowed out, so that the battery pack can only be taken out from the side of the slit groove when it is taken out, which makes the removal of the battery pack more convenient and ergonomically designed. However, after the battery pack is mounted to the frame tube, it is usually necessary to provide a wiring and a connector to transfer the power provided by the battery pack to the electric motor. This patented battery pack mounting structure does not provide enough space to organize the messy wires. Therefore, when the battery pack is to be assembled to the battery pack fixing structure, the assembly is difficult due to the messy wire configuration, and it is not advantageous for maintenance and replacement work when there is a problem with the wire.

In addition, the German utility model patent DE20072006211U1 discloses a power supply device for an electric bicycle, wherein the power supply device is constituted by a battery and the inside of the frame tube of the bicycle has a receiving space. The power supply device is detachably connected to an accommodation space inside the frame tube, and the battery has a large battery cover. The power supply device for an electric bicycle taught by the patent has a bicycle frame having an upper tube having an accommodation space. The power supply device is detachably coupled to the accommodation space of the bicycle frame. The power supply unit contains a battery with a large battery cover. The lower surface of the battery cover is placed against the opening of the receiving space and is filled with the surface of the frame tube of the frame. The power supply device includes a housing having two opposite pins inserted into the receiving space. The housing of the power supply device further has a protrusion disposed in a gap between the upper tube and the housing. The battery is in the form of a rectangle and is detachably housed within the battery compartment of the housing. However, this patent still has the disadvantage that the wire present in the aforementioned battery pack fixing structure is difficult to organize and the wire is not easily repaired or replaced.

US Patent No. 20140141310A1 proposes a battery fixing structure for a seat tube of an electric bicycle. The battery fixing structure of this patent comprises a tube body, a cap body, and a cover body. The tubular body has a receiving passage, and the cap body has an assembled component. One end of the assembled component is assembled to the tubular body, and the other end has a manipulation block exposed outside the seat tube. The cap body has a passage that communicates with the receiving passage of the tubular body. When the battery pack is inserted into the receiving passage of the tubular body, the battery pack is connected to the passage of the cap body. The cover body is disposed between the seat tube and the tube body and tightly sleeved to the tube body. Therefore, the tube body can be closely positioned in the seat tube, so that the battery pack is stably positioned in the seat tube. In addition, the tubular body is assembled to the cap body via the fixing device so that the user can separate the cap body from the battery pack from the seat tube via the manipulation block of the cap body to replace the battery pack. However, this patent still has the disadvantage that the wire present in the aforementioned battery pack fixing structure is difficult to organize and the wire is not easily repaired or replaced. Moreover, since it is necessary to provide a tube body, a cover body, and a cap body in the seat tube to accommodate the battery pack, the design of the seat tube is complicated, and the manufacturing cost is also greatly increased.
