Abstract
The utility model discloses an electric bicycle wheel hub with a built-in lithium battery pack. The electric bicycle wheel hub comprises a driving wheel hub and a driven wheel hub, and is characterized in that a motor cabin used for placing and fixing a driving motor is arranged in the driving wheel hub, the two sides of the middle of the driven wheel hub are provided with bearings used for connecting a wheel hub shaft, a battery cabin used for accommodating the lithium battery pack is arranged between the wheel hub shaft and a wheel hub casing of the driven wheel hub, the lithium battery pack is fixedly connected with the wheel hub shaft, a wire passing hole is formed in the wheel hub shaft, a power supply wire of the lithium battery pack is connected with the driving motor through the wire passing hole, and a charging wire of the lithium battery pack is connected with an external power supply through the wire passing hole. The electric bicycle wheel hub with the built-in lithium battery pack has the advantages that the lithium battery pack is built in the wheel hub, and the weight and the size of an electric bicycle are reduced, so the electric bicycle is more portable and more attractive, and meanwhile, the environment is favorably protected.
Description
[technical field]
The utility model relates to a kind of electric vehicle hub, is specifically related to a kind of electric vehicle hub of built-in lithium battery group.
[background technology]
Ride battery-driven car as conveniently trip mode of one, problem that can transport solution difficulty.Traditional battery-driven car adopts external lead-acid battery power supply mostly, and lead-acid battery is with low cost, but it exists that volume is large, the problem of Heavy Weight and not environmental protection, can not meet people's demand portable, attractive in appearance to trip instrument, is also unfavorable for environmental protection simultaneously.
[summary of the invention]
For above-mentioned defect, the utility model discloses a kind of electric vehicle hub of built-in lithium battery group, lithium cell group is built in wheel hub, reduce the weight and volume of battery-driven car, make it more portable and attractive in appearance, be beneficial to environmental protection simultaneously.
The technical solution of the utility model is as follows:
A kind of electric vehicle hub of built-in lithium battery group, comprise drive hub and driven wheel hub, in described drive hub, be provided with for placing and the motor bin of fixed drive motor, both sides, described driven wheel hub middle part are provided with the bearing for connecting hub spindle, between the hub shell of driven wheel hub and hub spindle, be provided with the battery compartment for holding lithium cell group, described lithium cell group is fixedly connected with hub spindle; Described hub spindle is provided with cable-through hole, and the supply line of described lithium cell group is connected with described drive motor by cable-through hole, and the charging wire of lithium cell group is connected with external power supply by cable-through hole.
Lithium cell group is built in driven wheel hub inside by the electric vehicle hub of built-in lithium battery group of the present utility model, without separately establishing battery compartment in battery-driven car outside, simplified the structure of battery-driven car, makes it more attractive in appearance; Adopt the power supply of lithium cell group, lithium cell group is lightweight compared with traditional lead-acid battery, volume is little, makes battery-driven car more portable, has also reduced the heavy metal pollution that uses lead-acid battery to cause environment simultaneously, is conducive to environmental protection.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the utility model embodiment.
[specific embodiment]
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.
As shown in Figure 1, the electric vehicle hub of built-in lithium battery group of the present utility model comprises drive hub 7 and driven wheel hub 6, in described drive hub 7, be provided with for placing and the motor bin 9 of fixed drive motor 8, described driven wheel hub 6 both sides, middle part are provided with the bearing 2 for connecting hub spindle 1, for example, in concrete enforcement, hub spindle 1 is fixed with vehicle body, the rotation that coordinates with hub spindle 1 by bearing 2 of driven wheel hub 6; Between the hub shell 5 of driven wheel hub 6 and hub spindle 1, be provided with the battery compartment 4 for holding lithium cell group 3, described lithium cell group 3 is fixedly connected with hub spindle 1; Described hub spindle 1 is provided with cable-through hole, and the supply line of described lithium cell group 3 is connected with described drive motor 8 by cable-through hole, is that drive motor 8 is powered by lithium cell group, and drive motor 8 drives drive hub 7 to rotate, and drives vehicle to advance; The charging wire of lithium cell group 3 is connected with external power supply by cable-through hole, so that be the charging of lithium cell group.
Lithium cell group 3 is built in driven wheel hub 6 inside by the electric vehicle hub of built-in lithium battery group of the present utility model, without separately establishing battery compartment in battery-driven car outside, simplified the structure of battery-driven car, makes it more attractive in appearance; Adopt lithium cell group 3 to power; lithium cell group is lightweight compared with traditional lead-acid battery, volume is little, thereby has alleviated the weight and volume of battery-driven car, makes battery-driven car more portable; also reduced the heavy metal pollution that uses lead-acid battery to cause environment, be conducive to environmental protection simultaneously.
Preferably, described lithium cell group 3 is distributed in the both sides of described hub spindle 1, and load is evenly distributed, and is beneficial to the balance of driven wheel hub 6 and battery-driven car;
Preferably, described battery compartment 4 is the cylindrical cavity coaxial with described hub spindle 1, be beneficial to guarantee when driven wheel hub 6 turns round do not produce interference with the lithium cell group 3 being fixed on hub spindle 1, be coaxially arranged with and be beneficial to the volume that reduces battery compartment 4, guarantee the intensity of driven wheel hub 6.
Above-described embodiment of the present invention, does not form limiting the scope of the present invention.Any modification of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in claim protection domain of the present invention.
