[0035] Certain words are used in the specification and claims to refer to specific components. Those with ordinary knowledge in the field should understand that manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but rather use differences in components' functions as the criteria for distinction. The term "including" mentioned throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to".

[0036] See also Figure 1 and Figure 2 According to one embodiment, the electric bicycle 1 comprises a frame 12, two wheels 14, a motor 16 ( Figure 1 The two wheels 14 are pivotally connected to the front and rear sides of the frame 12. The motor 16 is disposed on the frame 12 (e.g., adjacent to the large chain plate) and mechanically connected to one of the wheels 14 (e.g., linked to the rear wheel through the large chain plate, chain). The battery holder assembly 18 is fixedly disposed on the frame 12 (the tube of the frame 12, such as the down tube 122) and electrically connected to the motor 16; Figure 1 , the electrical connection between the battery holder assembly 18 and other electronic devices is indicated by a thick line. The removable battery 20 is removably mounted on the battery holder assembly 18. Thus, the removable battery 20 provides power, and the battery holder assembly 18 receives power to drive the motor 16 and control the operation of the motor 16. In addition, in this embodiment, the power system of the electric bicycle 1 includes the battery holder assembly 18 and the removable battery 20.

[0037] See also Figures 3 to 5 In this embodiment, the battery holder assembly 18 includes a battery holder 182, a controller 184, a first external electrical connector 186, and a second external electrical connector 188. The battery holder 182 is in the shape of an elongated strip (i.e., the entire structure extends substantially along the length direction D1 (indicated by a double-headed arrow in the figure)) and is disposed on the lower tube 122 of the frame 12 (see FIG. Figure 1 The battery holder 182 includes a holder 1822, a first electromechanical connection structure 1824 (on Figure 3 and Figure 4 ) and the second electromechanical connection structure 1826 (indicated by a dotted frame in Figure 3 and Figure 4The seat body 1822 is fixed to the lower tube 122 of the frame 12, and the first electromechanical connection structure 1824 and the second electromechanical connection structure 1826 are arranged on the seat body 1822 in a relative manner in the length direction D1. An accommodation space 182a is formed between the seat body 1822, the first electromechanical connection structure 1824, and the second electromechanical connection structure 1826. The controller 184 is fixedly connected to the seat body 1822 and is electrically connected to the first electromechanical connection structure 1824. In this embodiment, the controller 184 is directly fixed to the housing of the seat body 1822, and the controller 184 and the first electromechanical connection structure 1824 are directly electrically connected by wires in the housing. In actual operation, the electrical connection between the controller 184 and the first electromechanical connection structure 1824 can also be achieved by docking the electrical connectors (for example, corresponding electrical connectors are provided on the controller 184 and the seat 1822, and the electrical connector on the seat 1822 is directly electrically connected to the first electromechanical connection structure 1824); at this time, the controller 184 and the seat 1822 are structurally connected in a detachable manner.

[0038] In addition, in this embodiment, the first external electrical connector 186 is disposed on the seat body 1822 adjacent to the second electromechanical connection structure 1826, and in this embodiment, the first external electrical connector 186 is an electrical connector. The first external electrical connector 186 is electrically connected to the second electromechanical connection structure 1826 (for example, directly connected by wires to achieve electrical connection). The first external electrical connector 186 can be electrically connected to other on-board electronic devices. In this embodiment, the electric bicycle 1 also includes two electronic devices, namely a headlight 22 and a human-machine interface 24 (for example, disposed on the handlebar or handlebar of the frame 12, such as Figure 1 As shown; wherein, the human-machine interface 24 can be a remote operation panel as a controller 184 in actual operation, or it can be other electronic devices with a human-machine interface 24, such as a navigation device). The electrical connection between the first external electrical connector 186 and the headlight 22 and the human-machine interface 24 is achieved through a connecting wire set 187. One end of this connecting wire set 187 is provided with an electrical connector (connected to the electrical connector of the first external electrical connector 186), and the other end can be provided with a connection interface for the headlight 22 and the human-machine interface 24 to be plugged in (such as a USB hub, the headlight 22 and the human-machine interface 24 are both equipped with USB connection cables) or directly connected (or plugged in) to the headlight 22 and the human-machine interface 24. However, the present invention is not limited to this. For example, the first external electrical connector 186 is a wire set, which is directly connected to the second electromechanical connection structure 1826 and protrudes from the battery fixing seat 182 to extend outward (and then electrically connected to the headlight 22 and the human-machine interface 24). In addition, in this embodiment, in terms of structural logic, the combination of the first external electrical connector 186 and the connecting wire set 187 can also be regarded as the first external electrical connector 186 (serving as a medium for electrically connecting the second electromechanical connection structure 1826 with the vehicle light 22 and the human-machine interface 24).

[0039] In this embodiment, the controller 184 is electrically connected to the second external electrical connector 188, and is electrically connected to the motor 16 via the second external electrical connector 188. In this embodiment, the second external electrical connector 188 is a wire group, extending from the inside of the controller 184 to the outside, and connected to the motor 16. In actual operation, the second external electrical connector 188 can also be similar to the first external electrical connector 186, and is an electrical connector provided on the controller 184. This electrical connector can be electrically connected to the motor 16 via other wire groups. The above-mentioned descriptions on the first external electrical connector 186 and the connecting wire group 187 are also applicable here and are not repeated.

[0040] In addition, in this embodiment, the removable battery 20 includes a device body 202, a third electromechanical connection structure 204 ( Figure 3 and Figure 4 ) and the fourth electromechanical connection structure 206 (indicated by a dotted frame in Figure 3 and Figure 4 ), the third electromechanical connection structure 204 and the fourth electromechanical connection structure 206 are disposed at opposite ends (end portions) of the device body 202 in the length direction D1 and are electrically connected through the inside of the device body 202. The removable battery 20 is removably connected to the first electromechanical connection structure 1824 and the second electromechanical connection structure 1826 of the battery holder 182 through the third electromechanical connection structure 204 and the fourth electromechanical connection structure 206, respectively, so that the removable battery 20 is removably fixed on the battery holder 182 and accommodated in the accommodation space 182a of the battery holder 182. In this embodiment, the device body 202 includes a device housing 2022, at least one single battery 2024 and a control circuit board 2026, and the at least one single battery 2024 and the control circuit board 2026 are accommodated in the device housing 2022. The third electromechanical connection structure 204 and the fourth electromechanical connection structure 206 are disposed on the device housing 2022. The control circuit board 2026 is electrically connected to the third electromechanical connection structure 204 , the fourth electromechanical connection structure 206 and the at least one battery cell 2024 .

[0041] Therefore, in this embodiment, when the removable battery 20 is installed on the battery holder assembly 18, the controller 184 can be electrically connected to the headlight 22 and the human-machine interface 24 via the first electromechanical connection structure 1824, the third electromechanical connection structure 204, the control circuit board 2026, the fourth electromechanical connection structure 206, the second electromechanical connection structure 1826, and the first external electrical connection member 186, and can control the operation of the headlight 22 and the human-machine interface 24 according to the design. In addition, in this embodiment, the device body 202 also includes an electrical interface 2028, which can be used as an electrical connection with other electronic devices. For example, when the removable battery 20 is removed from the battery holder 182, the removable battery 20 can be charged through the electrical interface 2028. For another example, the removable battery 20 installed on the battery holder assembly 18 can still provide power to other electronic devices through the electrical interface 2028.

[0042] On the other hand, in general electric bicycles, the onboard electronic devices usually need to be independently wired to connect to the controller, which results in too many connecting wires and difficulty in routing. In particular, when the connecting wires need to pass by the battery (or its fixing seat), the required installation space of the place (i.e., including the battery, the fixing seat, and the connecting wires) will increase (or the cross-sectional area of ​​the place will need to be increased), making installation difficult. In this embodiment, the headlights 22 and the human-machine interface 24 are not completely independently wired to the controller 184, but are indirectly connected through the battery fixing seat 182 and the removable battery 20; therefore, in principle, no connecting wires will pass by the battery fixing seat 182. This structural configuration relatively reduces the space required for the layout of the connecting wires, simplifies the wiring, and facilitates future maintenance.

[0043] In addition, in this embodiment, the first electromechanical connection structure 1824 and the third electromechanical connection structure 204 are matched in structure and electrical properties. Figure 3 As shown, the first electromechanical connection structure 1824 includes a mechanical connection part and an electrical connection part. The electrical connection part includes the electrical contacts of the electrical connector; the mechanical connection part includes three bumps and the structure of the electrical connector itself. Figure 4 As shown, the third electromechanical connection structure 204 also includes a mechanical connection part and an electrical connection part. The electrical connection part includes an electrical contact of an electrical connector (matching with the electrical connector of the first electromechanical connection structure 1824); the mechanical connection part includes three grooves (matching with the three bumps of the first electromechanical connection structure 1824) and the structure of the electrical connector itself.

[0044] Likewise, the second electromechanical connection structure 1826 matches the fourth electromechanical connection structure 206 in terms of structure and electrical properties. Figure 4As shown, the second electromechanical connection structure 1826 includes a mechanical connection part and an electrical connection part. The electrical connection part includes the electrical contacts of the electrical connector; the mechanical connection part includes a bump, a movable latch, two guide grooves and the structure of the electrical connector itself. Figure 3 As shown, the fourth electromechanical connection structure 206 also includes a mechanical connection part and an electrical connection part. The electrical connection part includes an electrical contact of an electrical connector (matching with the electrical connector of the second electromechanical connection structure 1826); the mechanical connection part includes a groove (matching with the protrusion of the second electromechanical connection structure 1826), a card slot (matching with the movable card latch of the second electromechanical connection structure 1826), two side plates (matching with the guide groove of the second electromechanical connection structure 1826) and the structure of the electrical connector itself. Among them, the movable latch of the second electromechanical connection structure 1826 can move along the length direction D1 to be inserted into the slot of the fourth electromechanical connection structure 206 (for example, by setting a spring in the battery fixing seat 182 to push the movable latch, and the spring allows the movable latch to be retracted into the battery fixing seat 182 under external force, and can drive the movable latch to protrude outward to be inserted into the slot), or disengage from the slot (for example, by operating the lock 1828 set on the battery fixing seat 182 and linked to the movable latch).

[0045] In actual operation, the specific implementation of the structural and electrical matching of the first electromechanical connection structure 1824 and the third electromechanical connection structure 204 is not limited to the present embodiment. For example, the structural matching is achieved by the sliding connection of the slider and the slide groove. For another example, the electrical matching is achieved by a resilient protrusion (such as a pogo pin, a spring) against the metal pad. In addition, the specific implementation of the structural and electrical matching of the second electromechanical connection structure 1826 and the fourth electromechanical connection structure 206 is also the same, which will not be repeated. In addition, the battery holder 182 also includes a spring 1830. When the removable battery 20 is installed on the battery holder assembly 18, the spring 1830 is elastically deformed by the push of the removable battery 20. The deformed spring 1830 helps the removable battery 20 to exit the accommodating space 182a of the battery holder 182.

[0046] like Figure 1 As shown, in this embodiment, the battery holder assembly 18 is fixed to the outer surface of the lower tube 122 of the frame 12, and other connecting wires are routed in the lower tube 122 or other tubes of the frame 12. In actual operation, the battery holder assembly 18 can also be integrated with the lower tube 122 structure and arranged in the lower tube 122, which can increase the overall appearance of the electric bicycle 1 and enhance the protection of the battery holder assembly 18 (i.e., through the structure of the lower tube 122 itself). Please refer to Figure 6, which is a schematic diagram of an embodiment in which a battery holder assembly 18 is disposed in a tube (e.g., a lower tube 122') of a vehicle frame 12. In this example, the lower tube 122' has an opening 122a. The battery holder assembly 18 is disposed in the lower tube 122' corresponding to the opening 122a. The connection wires of the battery holder assembly 18 (including a connection wire group 187, a first external electrical connection member 186 (e.g., a wire group), and a second external electrical connection member 188) are directly wired in the lower tube 122', so they extend inside the lower tube 122'. The removable battery 20' corresponding to this battery holder assembly 18 is similar in structure to the aforementioned removable battery 20, so in principle, the element symbols of the removable battery 20 are used. For other descriptions of the removable battery 20', please refer to the previous descriptions and drawings on the removable battery 20 and its variations, which will not be repeated.

[0047] See also Figure 1 , Figure 3 , Figure 4 and Figure 6 . Compared to the removable battery 20, the removable battery 20' further includes a decorative cover 208, which is fixed (for example, by adhesion, locking, structural engagement, etc.) on the device body 202 (device housing 2022). When the removable battery 20' is installed on the battery holder assembly 18, the decorative cover 208 is located in the opening 122a of the lower tube 122'. In actual operation, the contour of the decorative cover 208 can be designed so that after the removable battery 20' is installed on the battery holder assembly 18, the outer surface of the decorative cover 208 can fit closely around the opening 122a, and even form a complete tube body together with the lower tube 122' at that location. In addition to providing better protection for the battery holder assembly 18 and the removable battery 20', this structural configuration can also maintain the original appearance of the frame 12 because it will not protrude excessively from the lower tube 122'. In addition, in actual operation, the contour of the device housing 2022 can be directly designed to be directly in close contact with the opening 122a, and the aforementioned decorative cover 208 can be omitted. In addition, in actual operation, the seat body 1822 of the battery holder 182 of the battery holder assembly 18 can also be structurally integrated with the lower tube 122', for example, the lower tube 122' is also a part of the seat body 1822 to structurally connect the first electromechanical connection structure 1824 and the second electromechanical connection structure 1826; this structural design can reduce the cross-sectional area of ​​the lower tube 122' at the location (where the battery holder assembly 18 is disposed).

[0048] In summary, the battery holder assembly of the utility model comprises a battery holder, a controller and a first pair of external electrical connectors. The battery holder assembly is applied to an electric bicycle, so that the battery holder assembly has a relay effect in the electrical connection of the electric bicycle. The battery holder assembly is easy to install, maintain and repair, and can also reduce the space required for the layout of the connection line without affecting the appearance of the electric bicycle.
