Accordingly, power assistant bicycle is developed to solve the above problem; a power assistant bicycle can provide assistant power, so its driving distance can be effectively extended; in addition, the power assistant bicycle will not generate waste gas to result in air pollution; therefore, the impact to environment can be reduced; for the reason, the power assistant bicycle has become one of the alternatives of petrol vehicle. Moreover, many countries all are facing an accelerating trend of population ageing and the advantages of the power assistant bicycle are just very suitable for the elder; thus, the power assistant bicycle has become one of the most popular vehicles.

Currently, many different kinds of integrated power modules with different designs have been developed; for example, US Patent No. 9027681 provides an in-wheel power module. However, the range will be limited due to the limited battery capacity in the integrated power module. For the range extension, China Patent Application No. 200945896 provides a conventional power assistant bicycle with two batteries; China Patent Application No. 202827977U provides a power assistant bicycle with backup battery. However, these currently designs all need an additional battery input port besides the charging port, or an additional switch.

    DETAILED DESCRIPTION
    [0020] In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.
    [0021] With reference to FIG. 1 and FIG. 2 for a first schematic view and a second schematic view of the first embodiment of the present disclosure. As shown in FIG. 1, the integrated power module 1 may include a power port 11, a battery 12, a controller 13, a motor 14 and a connection element 15A.
    [0022] The power port 11 may include a first positive electrode terminal 110, a second positive electrode terminal 111 and a negative electrode terminal 112. The positive electrode of the battery 12 may be electrically coupled to one end 110A (the inner end) of the first positive electrode terminal 110. The negative electrode of the controller 13 may be electrically coupled to the negative electrode of the battery 12 and one end 112A (the inner end) of the negative electrode terminal 112; the positive electrode of the controller 13 may be electrically coupled to one end 111A (the inner end) of the second positive electrode terminal 111. The motor 14 may be electrically coupled to the controller 13. In the embodiment, the connection element 15A may be a port cap, which may detachably cap the power port 11; besides, the connection element 15 A may include a single circuit 151.
    [0023] FIG. 2 illustrates the schematic view of the internal power supply mode of the integrated power module 1. As shown in FIG. 2, when the user wants to execute the internal power supply mode to supply power to the controller 13 via the battery 12 built in the integrated power module 1 so as to drive the motor 14, the user can cap the power port 11 with the connection element 15A; at this time, the other end 110B (the outer end) of the first positive electrode terminal 110 may be electrically coupled to the other end 11 IB (the outer end) of the second positive electrode terminal 111 via the single circuit 151 to form a loop; the power supply direction is as shown by the arrows in FIG. 2. In this way, the built-in battery 12 of the integrated power module 1 can supply power to the controller 13 to drive the motor 14.
    [0024] With reference to FIG. 3 and FIG. 4 for a third schematic view and a fourth schematic view of the first embodiment of the present disclosure. FIG. 3 illustrates the schematic view of the external power supply mode of the integrated power module 1. As shown in FIG. 3, when the built-in battery is exhausted after the electric bicycle travels for a certain distance and the user wants to use the external battery EB to supply power to the controller 13 to drive the motor 14, the user may remove the connection element 15A from the power port 11; then, the user may couple the other end 11 IB of the second positive electrode terminal 111 to the positive electrode of the external battery EB, and couple the other end 112B (the outer end) of the negative electrode terminal 112 to the negative electrode of the external battery EB via the external battery connector 16 so as to form a loop; the power supply direction is as shown by the arrows in FIG. 3. In this way, the integrated power module 1 may supply power to the controller 13 via the external battery EB to drive the motor 14.
    [0025] FIG. 4 illustrates the schematic view of the charge mode of the integrated power module 1. As shown in FIG. 4, when the user wants to charge the built-in battery 12 of the integrated power module 1, the user can remove the connection element 15A from the power port 11; then, the user can couple the other end 110B (the outer end) of the first positive electrode terminal 110 to the positive electrode of the charger CR, and couple the other end 112B (the outer end) of the negative electrode terminal 112 to the negative electrode of the charger CR via the charger connector 17 so as to form a loop; the power supply direction is as shown by the arrows in FIG. 4. In this way, the integrated power module 1 can charge the battery 12 via the external charger CR.
    [0026] As described above, by means of the special circuit design and the connection element 15A, the integrated power module 1 can execute three different modes, internal power supply mode, external power supply mode and charge mode, only by the power port with two positive electrode terminal 110, 111 and one negative electrode terminal 112 rather than additional battery port, charger port, detection circuit or switch circuit; accordingly, the integrated power module 1 can be of high expandability and more flexible in use. Therefore, the integrated power module 1 is very suitable for various electric bicycle.
    [0027] It is worthy to point out that the capacity of the built-in battery of a conventional integrated power module is not enough for an electric bicycle to travel for a long distance. On the contrary, according to one embodiment of the present disclosure, the integrated power module can not only supply the power to the electric bicycle via a built-in battery, but also can directly couple to an external battery; in this way, the integrated power module can provide sufficient power for the electric bicycle to travel a long distance; therefore, the driving range of the electric bicycle can be further extended.
    [0028] Besides, the conventional integrated power module has no expansion function, so its power port can only be connected to a charger; therefore, the expandability of the conventional integrated power module is low and limited in function. On the other hand, the conventional integrated power module needs to connect to an external battery via an additional battery port or an additional detection circuit/switch circuit, which will significantly increase the cost of the conventional integrated power module. On the contrary, according to one embodiment of the present disclosure, by means of the special circuit design, the integrated power module may only need two positive electrode terminals and one negative electrode terminal to execute at least three different modes (internal power supply mode, external power supply mode and charge mode) without additional battery port, charger port, detection circuit or switch circuit; therefore, the quantity of the ports of the integrated power module can be minimized, so the cost of the integrated power module can be significantly reduced.
    [0029] Furthermore, according to one embodiment of the present disclosure, the integrated power module may include a port cap; when the power port is capped by the port cap, the integrated power module can execute the internal power supply mode; in addition, the port cap can also achieve dust-proof and water proof effects to protect the power port when the power port is capped by the port cap; therefore, the failure rate of the integrated power module can be reduced and its service life can be longer. As describe above, the present disclosure definitely has an inventive step.
    [0030] With reference to FIG. 5 and FIG. 6 for a first schematic view and a second schematic view of the second embodiment of the present disclosure. As shown in FIG. 5, the integrated power module 1 may include a power port 11, a battery 12, a controller 13, a motor 14 and a connection element 15B.
    [0031] The power port 11 may include a first positive electrode terminal 110, a second positive electrode terminal 111 and a negative electrode terminal 112. The positive electrode of the battery 12 may be electrically coupled to one end 110A (the inner end) of the first positive electrode terminal 110. The negative electrode of the controller 13 may be electrically coupled to the negative electrode of the battery 12 and one end 112A (the inner end) of the negative electrode terminal 112; the positive electrode of the controller 13 may be electrically coupled to one end 111A (the inner end) of the second positive electrode terminal 111. The motor 14 may be electrically coupled to the controller 13. The difference between the embodiment and the previous embodiment is that the connection element 15B may be an internal switch installed inside the power port 11; the connection element 15B may be turned on to electrically couple the other end 110B (the outer end) of the first positive electrode terminal 110 to the other end 11 IB (the outer end) of the second positive electrode terminal 111, or turned off to cut off the electrical connection between the other end 110B (the outer end) of the first positive electrode terminal 110 and the other end 111B (the outer end) of the second positive electrode terminal 111.
    [0032] FIG. 6 illustrates the schematic view of the internal power supply mode of the integrated power module 1. As shown in FIG. 6, when the user wants to execute the internal power supply mode, the user can switch on the connection element 15B to electrically couple the other end 11 OB (the outer end) of the first positive electrode terminal 110 to the other end 11 IB (the outer end) of the second positive electrode terminal 111; at this time, the other end 11 OB (the outer end) of the first positive electrode terminal 110 can be electrically coupled to the other end 11 IB (the outer end) of the second positive electrode terminal 111 to form a loop; the power supply direction is as shown by the arrows in FIG. 6. In this way, the built-in battery 12 of the integrated power module 1 can supply power to the controller 13 to drive the motor 14.
    [0033] With reference to FIG. 7 and FIG. 8 for a third schematic view and a fourth schematic view of the second embodiment of the present disclosure. FIG. 7 illustrates the schematic view of the external power supply mode of the integrated power module 1. As shown in FIG. 7, when the user wants to supply power to the controller 13 to drive the motor 14 via an external battery EB, the user can switch off the connection element 15B to cut off the electrical connection between the other end 11 OB (the outer end) of the first positive electrode terminal 110 and the other end 11 IB (the outer end) of the second positive electrode terminal 111; then, the user can electrically couple the other end 11 IB (the outer end) of the second positive electrode terminal 111 to the positive electrode of the external battery EB, and electrically couple the other end 112B (the outer end) of the negative electrode terminal 112 to the negative electrode of the external battery EB via an external battery connector 16 to form a loop; the power supply direction is as shown by the arrows in FIG. 7. In this way, the integrated power module 1 may supply power to the controller 13 via the external battery EB to drive the motor 14.
    [0034] FIG. 8 illustrates the schematic view of the charge mode of the integrated power module 1. As shown in FIG. 8, when the user wants to charge the built-in battery 12 of the integrated power module 1, the user can switch off the connection element 15B to cut off the electrical connection between the other end 110B (the outer end) of the first positive electrode terminal 110 and the other end 11 IB (the outer end) of the second positive electrode terminal 111; then, the user can electrically couple the other end 110B (the outer end) of the first positive electrode terminal 110 to the positive electrode of the charger CR, and electrically couple the other end 112B (the outer end) of the negative electrode terminal 112 to the negative electrode of the charger CR to form a loop; the power supply direction is as shown by the arrows in FIG. 8. In this way, the integrated power module 1 can charge the battery 12 via the external charger CR.
    [0035] As described above, by means of the special circuit design and the connection element 15B, the integrated power module 1 can execute three different modes, internal power supply mode, external power supply mode and charge mode, only by the power port with two positive electrode terminal 110, 111 and one negative electrode terminal 112 rather than additional battery port, charger port, detection circuit or switch circuit; accordingly, the integrated power module 1 can be of high expandability and more flexible in use.

The embodiment illustrates the usage situations of the integrated power module according to the embodiment of the present disclosure.
    [0037] As shown in FIG. 9A, the integrated power module 1 may be mounted on an electric bicycle 2 and integrated with the crank shaft of the electric bicycle 2, which is the middle-mounted type design.
    [0038] As shown in FIG. 9B, when the user wants to execute the internal power supply mode, the user can cap the power port 11 of the integrated power module 1 by the connection element 15A (port cap) to electrically couple the first positive electrode terminal to the second positive electrode terminal of the integrated power module 1; in this way, the controller of the integrated power module 1 can be charged by the built-in battery of the integrated power module 1.
    [0039] As shown in FIG. 10A, after the built-in battery of the integrated power module 1 is exhausted, the user needs to execute the charge mode; then, the user may directly couple the power port 11 to a charger.
    [0040] As shown in FIG. 10B, the user can remove the connection element 15A (port cap) from the power port 11; afterward, the user can electrically couple the first positive electrode terminal of the integrated power module 1 to the positive electrode of the charger CR, and electrically couple to the negative electrode of the integrated power module 1 to the negative electrode of the charger CR via a charger connector 17; in this way, the built-in battery of the integrated power module 1 can be charged by the external charger CR.
    [0041] As shown in FIG. 11, when the user wants to ride the electric bicycle 2 to travel for a long distance, the user can couple the integrated power module 1 to an external battery EB. The user can electrically couple the second positive electrode terminal of the integrated power module 1 to the positive electrode of the external battery EB, and electrically couple to negative electrode of the integrated power module 1 to the negative electrode of the external battery EB; in this way, the integrated power module 1 can supply more power to the electric bicycle 2.
