Description

Technical Field

[0001] This application relates to a motor structure, and more particularly to a motor structure with a replaceable control module. Background Technology

[0002] A traditional mid-drive motor mainly consists of a motor housing, a motor, a clutch gear module, and a control module housed inside the motor housing. The control module controls the motor to drive the clutch gear module, which forms a speed-changing ratchet, thereby increasing the output torque of the mid-drive motor.

[0003] However, the yield test of the above-mentioned mid-drive motor after assembly was not up to standard. It was necessary to test and repair the motor, control module and clutch gear module separately. However, the motor housing did not have a dedicated maintenance port for the control module or clutch gear module. As a result, the testers had to completely disassemble the motor housing in order to test and repair the internal control module or clutch gear module. Afterwards, the complex motor housing had to be reassembled, which caused great inconvenience to the testers.

[0004] In view of this, the applicant has devoted himself to studying the aforementioned prior art and applying theoretical principles to try his best to solve the above-mentioned problems, which has become the target of the applicant's improvement. Summary of the Invention

[0061] Please refer to Figures 1 to 6As shown, this application provides a motor structure with a replaceable control module. This motor structure 10 mainly includes a main body 1 and a detachable motor 2.

[0062] like Figures 1 to 2 , Figures 5 to 6 As shown, the main unit 1 includes a chassis 11, a removable cover 12, and a control module 13. The chassis 11 is made of metal materials such as iron, stainless steel, and aluminum alloy, while the removable cover 12 is made of materials commonly used to make heat dissipation fins, such as copper and aluminum.

[0063] The detailed description is as follows: The chassis 11 has a first surface 111, a second surface 112 and a maintenance port 113. The chassis 11 has a gear mounting area 114 arranged adjacent to the maintenance port 113. A first through hole 115 is provided in the middle of the gear mounting area 114. The first through hole 115 passes through the first surface 111 and the second surface 112. The maintenance port 113 is opened from the first surface 111. The second surface 112 is provided with a second through hole 116 corresponding to the maintenance port 113.

[0064] In addition, the gear mounting area 114 of this embodiment has a generally cylindrical mounting space, and the chassis 11 has an arc-shaped end edge 117 formed at the junction of the gear mounting area 114 and the maintenance port 113 and a U-shaped peripheral wall 118 arranged along the periphery of the maintenance port 113 away from the gear mounting area 114.

[0065] like Figures 1 to 6 As shown, the detachable cover 12 can be detachably fixed to the chassis 11 and cover the maintenance port 113. Alternatively, the detachable cover 12 can be assembled to the chassis 11 and cover the maintenance port 113, or the detachable cover 12 can be removed from the chassis 11 and expose the maintenance port 113. The outer wall of the detachable cover 12 has multiple heat dissipation fins 121, and the inner wall of the detachable cover 12 has a heat conduction plate 122.

[0066] In addition, the detachable cover 12 has multiple protruding ribs 123 on one side and a U-shaped locking block 124 extending from the inner wall surface. The multiple protruding ribs 123 are located inside the arc-shaped end edge 117 and stop each other with the arc-shaped end edge 117. The U-shaped locking block 124 is engaged inside the U-shaped peripheral wall 118.

[0067] Furthermore, the detachable cover 12 extends to an arc-shaped enclosure 125 that spans the two ends of the U-shaped latch 124 and is integrally formed with the U-shaped latch 124. The arc-shaped enclosure 125 has a recess 126 and is configured corresponding to the arc-shaped end edge 117. Multiple protruding ribs 123 extend from the arc-shaped enclosure 125.

[0068] like Figures 2 to 6As shown, the control module 13 includes a circuit board 131 fixed to the inner wall of the removable cover 12 and multiple electronic components 132 mounted on the circuit board 131. Some of the multiple electronic components 132 include multiple heating components 133, which are thermally attached to a heat-conducting plate 122, which extends from the U-shaped clip 124.

[0069] like Figures 3 to 4 As shown, the main body 1 also includes a thermal pad 16, which is sandwiched between the heat-conducting plate 122 and multiple heat-generating components 133. The thermal pad 16 is made of paraffin wax, silicone resin or thermally conductive silicone. The thermal pad 16 is used to fill the gaps in the thermal interface formed between the heat-conducting plate 122 and the surfaces of the multiple heat-generating components 133, so that the heat generated by the multiple heat-generating components 133 can be conducted to the multiple heat dissipation fins 121 through the thermal pad 16 and the heat-conducting plate 122 for heat dissipation.

[0070] In addition, such as Figures 1 to 2 , Figure 5 As shown, the main body 1 also includes multiple connectors 18, which are installed on one side of the chassis 11 near the maintenance port 113.

The chassis 11 has multiple first locking holes 119, the removable cover 12 has multiple second locking holes 127 and multiple third locking holes 128, the circuit board 131 has multiple fourth locking holes 135, the heat-conducting plate 122 has multiple first fixing holes 129, each heat-generating component 133 has a second fixing hole 134, and the heat-conducting pad 16 has multiple third fixing holes 161. A portion of the screws 17 are respectively fixed to each of the first... Locking holes 119 and 127 allow the removable cover 12 to be detachably fixed to the chassis 11. Another set of screws 17' are respectively fixed to the third locking holes 128 and the fourth locking holes 135, allowing the circuit board 131 to be detachably fixed to the removable cover 12. The remaining set of screws 17" are fixed to the first fixing holes 129, the second fixing holes 134 and the third fixing holes 161, allowing the heating components 133 to be detachably fixed to the heat-conducting plate 122.

[0073] like Figures 1 to 2 , Figures 5 to 6 As shown, the detachable motor 2 includes a motor housing (not shown) and a stator (not shown) and a rotor (not shown) housed inside the motor housing. The motor housing is detachably fixed to the second surface 112, so that the detachable motor 2 can be detachably fixed to the main body 1. That is, the detachable motor 2 can be assembled or disassembled to the main body 1. The detachable motor 2 has a drive shaft 21 that passes through the second through hole 116 and meshes with the gear module 14, so that the drive shaft 21 can drive the driven main shaft 15 to rotate through the gear module 14. The driven main shaft 15 can be used to connect to the electric bicycle pedal (not shown), but is not limited thereto.

[0074] like Figures 1 to 6 As shown, the motor structure 10 of this application is in use. It utilizes a gear module 14 housed in a housing 11. The housing 11 has a maintenance port 113, which is detachably covered by a removable cover 12. A circuit board 131 is fixed to the inner wall of the removable cover 12. The detachable motor 2 is detachably fixed to the main body 1, allowing the detachable motor 2 and control module 13 to be removed from the main body 1 for inspection or replacement. The gear module 14 can be inspected through the maintenance port 113. Therefore, the motor structure 10 of this application provides convenient inspection or replacement of the detachable motor 2, control module 13, and gear module 14, offering advantages such as self-testing, reduced component replacement frequency, reduced assembly and testing time and manpower, and improved production yield and service life.

[0075] In addition, the outer wall of the detachable cover 12 extends with multiple heat dissipation fins 121, and the inner wall of the detachable cover 12 extends with a heat conduction plate 122, so that the heat generated by the multiple heat-generating components 133 can be conducted to the multiple heat dissipation fins 121 through the heat conduction pad 16 and the heat conduction plate 122, thereby enhancing the operating efficiency and service life of the control module 13.
