Description

Technical Field

[0001] This utility model relates to the field of electrical connection structures, specifically to a socket assembly, a mid-mounted motor, and a power-assisted bicycle. Background Technology

[0002] Currently, with the market's demand for diverse travel options, electric-assisted bicycles are increasingly favored by consumers. Electric-assisted bicycles use batteries as auxiliary power, have pedal functionality, and the motor directly handles the mechanical transmission, acting on the force applied during pedaling to convert electrical energy into kinetic energy, enabling both manual riding and electric assistance. The mid-mounted motor is installed at the bottom bracket of the frame, located in the lower middle part of the frame. Because the weight is concentrated near the bicycle's center of gravity, the weight distribution is reasonable, not affecting the overall front-rear weight balance of the bicycle. Manual riding offers relatively low resistance, and there is no additional electromagnetic resistance, making it the main development direction for electric-assisted bicycles.

[0003] However, due to the built-in controller and installation location of the mid-drive motor, the wiring between the mid-drive motor and the socket is rather cumbersome. Numerous different function wires are not only unsightly but also make wiring within the vehicle's wiring harness extremely inconvenient. The direct connection between the internal signal wires and the terminal blocks is not secure or reliable enough, making disassembly and replacement inconvenient. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of this utility model is to provide a socket assembly, a mid-mounted motor, and an electric bicycle.

[0005] According to the present invention, a socket assembly for connecting a mid-drive motor is provided, comprising: an integrated socket, a housing, and a circuit board;

[0006] The integrated socket includes: a base and metal pins;

[0007] The base has multiple sub-sockets on one side, and multiple pin holes are provided in the sub-sockets. The metal pins are respectively connected to the pin holes. While the metal pins are electrically connected to the circuit board, one end of the metal pin passes through the circuit board and protrudes outside, while the other end is located in the sub-socket, together with the sub-sockets, forming a plug of a preset type.

[0008] The integrated socket is connected to the housing, the plug is located inside the housing and can be electrically connected to the corresponding external connector, and one end of the metal pin exposed on the circuit board can be electrically connected to the pinhole reserved in the controller of the mid-mounted motor.

[0009] Furthermore, the housing has a threaded hole, and the base and the circuit board have a first fixing hole and a second fixing hole respectively at corresponding positions. Screws are sequentially passed through the second fixing hole and the first fixing hole and connected to the threaded hole.

[0010] Furthermore, a washer is fitted onto the screw, and the washer is located between the circuit board and the head of the screw.

[0011] Furthermore, a sealing groove is provided on the base, and a sealing ring is provided in the sealing groove. The sealing ring is located at the joint between the base and the housing.

[0012] Furthermore, the edge of the base extends outward along the length and width directions to form an extension, the first fixing hole is located in the extension, and the screw is located outside the sealing ring.

[0013] Furthermore, the housing has a ring-shaped structure, the integrated socket is connected to one side of the housing, and the plug is located within the space enclosed by the housing.

[0014] Furthermore, the preset plug-in types include: 3-hole plug-in, 4-hole plug-in, 8-hole plug-in, 9-hole plug-in, or a 6-hole plug-in specifically for power supplies.

[0015] Furthermore, the housing of the mid-drive motor is provided with a threaded hole, and the screw can be connected to the threaded hole on both the housing and the housing of the mid-drive motor.

[0016] A mid-drive motor according to the present invention includes the aforementioned socket assembly.

[0017] The electric bicycle provided by this utility model includes the aforementioned socket assembly, or includes the aforementioned mid-mounted motor.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention integrates multiple different types of plugs into a single socket, combining the motor and power / charging interface into a single module. This reduces the complex cable connections between the motor and socket in traditional designs, lowering installation complexity. The modular structure also facilitates quick troubleshooting and subsequent replacement or repair.

[0020] Because the cover of a mid-drive motor is generally large, conventional wiring methods can easily interfere with the power lines or terminals inside the cover. This invention reduces the space occupied by external cables and separate sockets, allowing for an optimized structural distribution of the mid-drive motor itself. Combined with an integrated socket, this further reduces exposed components and improves overall stability. Attached Figure Description

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a socket assembly for connecting a mid-drive motor, comprising: an integrated socket 1, a housing 2, and a circuit board 3.

[0027] The integrated socket 1 includes a base 8 and metal pins 6. Multiple sub-sockets are provided on one side of the base 8 for connecting to external plugs; the type of sub-socket can be selected according to actual needs. Multiple pin holes are provided inside the sub-sockets, and the metal pins 6 are connected to these pin holes respectively. While electrically connected to the circuit board 3, one end of the metal pin 6 passes through the circuit board 3 and protrudes outwards, while the other end is located inside the sub-socket, forming a preset type of plug-in together with the sub-socket. The preset type of plug-in includes: a 3-hole plug-in 10, a 4-hole plug-in 11, an 8-hole plug-in 12, a 9-hole plug-in 12, or a power supply-specific 6-hole plug-in 14.

[0028] The integrated socket 1 connects to the housing 2. The plug is located inside the housing 2 and can be electrically connected to the corresponding external connector. One end of the metal pin 6 exposed on the circuit board 3 can be electrically connected to the pinhole reserved in the controller inside the mid-drive motor. The housing of the mid-drive motor has threaded holes. The screw 5 can be connected to the threaded holes on both the housing 2 and the housing of the mid-drive motor, thereby achieving a wireless connection with the mid-drive motor and reducing installation complexity. The housing 2 has a ring-shaped structure, with the integrated socket 1 connected to one side of the housing 2, and the plug located within the space enclosed by the housing 2.

[0029] The housing 2 has a threaded hole 15. The base 8 and the circuit board 3 have a first fixing hole 16 and a second fixing hole 17 respectively. The screw 5 passes through the second fixing hole 17 and the first fixing hole 16 in sequence and is connected to the threaded hole 15. A washer 4 is fitted on the screw 5. The washer 4 is located between the circuit board 3 and the head of the screw 5, thereby realizing the assembly between the various components.

[0030] To enhance the sealing and waterproofing effect, a sealing groove is provided on the base 8, and a sealing ring 7 is installed in the sealing groove. The sealing ring is located at the joint between the base 8 and the housing 2. The edge of the base 8 extends outward along the length and width directions to form an extension. The first fixing hole 16 is located in the extension, and the screw 5 is located outside the sealing ring 7, making it suitable for outdoor or complex environments.

[0031] The socket assembly of this invention allows for an optimized structural distribution of the mid-drive motor. Combined with an integrated socket, it further reduces exposed components and improves overall stability. This mid-drive motor can be applied to products such as electric bicycles and power tools. Furthermore, reducing exposed interfaces and cables also lowers the risk of poor contact or damage due to vibration or impact.
