[0032] As described above, the control circuit board of a conventional controller for an electric motorcycle is fixed in the controller housing by full glue sealing. When the controller is working, the heat generated by the high-power devices on the control circuit board is transferred to the housing through the full glue for dissipation. This heat dissipation method has a poor heat dissipation effect and is prone to overheating of the controller due to poor heat dissipation, thereby shortening the life of key electronic components of the control circuit board. An embodiment of the present disclosure provides a controller 100 for an electric motorcycle to improve the heat dissipation of high-power devices. In the following, Figures 1 to 9 The principles of the present disclosure are described.

[0035] Figure 4 Shown Figure 1 FIG. 1 is a perspective schematic diagram of the connector 30 of the controller 100 . Figure 5 Shown Figure 1 The controller 100 is shown as a three-dimensional schematic diagram connected to the plug 40. Figure 6 Shown Figure 1 A side view of the controller 100 is shown from one perspective. Figure 7 Shown along Figure 6 A cross-sectional view taken along the section line AA shown in FIG. Figure 8 Shown Figure 1 A side view of the controller 100 is shown from another perspective. Figure 9 Shown along Figure 8 A cross-sectional view taken along the section line BB shown in FIG.

[0036] See also Figure 1 and Figure 2 The controller 100 described herein generally includes a housing 10 , a control circuit board 20 and a connector 30 .

[0037] The housing 10 includes an upper shell 11 and a metal lower shell 12 defining a housing cavity 101. The control circuit board 20 is located in the housing cavity 101. In some embodiments, the metal lower shell 12 includes a bottom wall 121 and side walls 122 connected to the bottom wall 121. The bottom wall 121 and the side walls 122 define the open-top housing cavity 101. The metal lower shell 12 may also be provided with a mounting portion 123 having a mounting hole 1230. The controller 100 is connected to the motorcycle frame, for example, via fasteners passing through the mounting hole 1230.

[0038] The open top of the accommodating chamber 101 is enclosed by the upper shell 11 and the connector 30. More specifically, the upper shell 11 is mounted on the top edge 1221 of the side wall 122 and can be made of metal or other non-metallic materials. The upper shell 11 is provided with an opening 110, and the connector 30 is installed in the opening 110 and closes the opening 110. The connector 30 includes a plurality of sockets 35 that are electrically connected to the control circuit board 20.

[0039] See also Figure 2 In some embodiments, the outer surface of the sidewall 122 is provided with a plurality of slots 1220, and the upper shell 11 includes a plurality of latches 112. The latches 112 are configured to be inserted into and engaged with the plurality of slots 1220, thereby mounting the upper shell 11 on the metal lower shell 12. Furthermore, the joint between the upper shell 11 and the metal lower shell 12 can be sealed with a sealant by dispensing, thereby preventing foreign matter from entering the accommodating cavity 101 through the gap at the joint between the upper shell 11 and the metal lower shell 12.

[0040] See also Figure 2 and Figure 7 The upper shell 11 and the top edge 1221 are matched in a concave-convex manner, which not only facilitates the installation and positioning of the two, but also helps to improve the sealing of the connection between the two. In some embodiments, the top edge 1221 is formed with a first step portion 1222, and the upper shell 11 has a second step portion 1122 that matches the first step portion 1222 in a concave-convex manner.

[0041] See also Figure 3 The control circuit board 20 includes a substrate 21 and a plurality of electronic devices 22 fixed to the substrate 21. More specifically, the substrate 21 includes a metal substrate 211 made of a metal material. The metal substrate 211 may be, for example, an aluminum substrate, a magnesium substrate, or the like. The metal substrate 211 is attached to the bottom wall 121, for example, in close contact with the bottom wall 121. In some embodiments, the metal substrate 211 may be fixed to the bottom wall 121, for example, by fasteners 341, 342, and 345. In some alternative embodiments, the metal substrate 211 may be fixed to the bottom wall 121 by a snap-fit ​​connection. The plurality of electronic devices 22 include power devices (also referred to as high-power devices) 221 that generate relatively high heat and other devices 222 that generate relatively low heat. The power devices 221 may include, for example, field-effect transistors (MOSFETs), large capacitors, and microcontrollers (MCUs). At least a portion of the power devices 221 is fixed to the metal substrate 211, for example, at least the MOSFETs and large capacitors are fixed to the metal substrate 211.

[0042] See also Figure 3 In some embodiments, in addition to the aforementioned metal substrate 211, the substrate 21 further includes a printed circuit board 212. Devices 222 other than the power device 221 can be fixed to the printed circuit board 212. A portion of the printed circuit board 212 overlaps with a portion of the metal substrate 211, and the overlapping areas are soldered together, for example, by soldering. The circuit of the printed circuit board 212 can be electrically connected to the circuit of the metal substrate 211 via the soldering material. Furthermore, fasteners 341 and 345 can sequentially pass through the printed circuit board 212 and the metal substrate 211, and then connect to the bottom wall 121.

[0043] See also Figure 2 and Figure 3 In some embodiments, a support column 124 is provided on the bottom wall 121 for supporting the printed circuit board 212. In some embodiments, two support columns 124 are provided, and fasteners 343 and 344 passing through the printed circuit board 212 are respectively connected to corresponding support columns 124.

[0044] In some alternative embodiments, the metal substrate 211 and the printed circuit board 212 are separated, and the circuit of the printed circuit board 212 is electrically connected to the circuit of the metal substrate 211 via wires. In this case, the printed circuit board 212 can be fixed to the bottom wall 121 by fasteners or by snap-fitting.

[0045] In some alternative embodiments, the entire substrate 21 may be made of metal material. That is, the substrate 21 includes the metal substrate 211 but does not include the printed circuit board 212, and the electronic components 22 are all fixed on the metal substrate 211, which is also within the scope of protection of the present disclosure.

[0046] The controller 100 provided in the embodiment of the present disclosure, compared with a conventional controller, has a substrate 21 of a control circuit board 20 including a metal substrate 211 made of a metal material, and a power device 221 with high heat generation can be arranged on the metal substrate 211, and the metal substrate 211 is attached to the bottom wall 121 of a metal lower shell 12 made of a metal material. The heat generated by the power device 221 can be directly conducted to the metal lower shell 12 through the metal substrate 211 for heat dissipation, thereby achieving a good heat dissipation effect, effectively avoiding overheating due to poor heat dissipation, and further shortening the life of key electronic components of the control circuit board 20.

[0047] In some embodiments, UV adhesive is used to cover the control circuit board 20, thereby covering the surface of the control circuit board 20 with a layer of UV adhesive. The UV adhesive layer can provide waterproof and corrosion-resistant protection for the control circuit board 20 with a relatively thin thickness, eliminating the need for full potting and sealing of the control circuit board 20, which helps reduce the weight of the controller 100. In addition, the UV adhesive layer has less impact on heat conduction than full potting.

[0048] See also Figure 2 、 Figure 4 and Figure 5 The multiple sockets 35 of the connector 30 are used to connect to multiple plugs 40 outside. In some embodiments, the multiple sockets 35 correspond to the motor, power supply, cadence, taillight, battery lock, central control, etc. Of course, the types of the multiple sockets 35 are not limited to this. Each socket 35 is provided with a pin 355 (see the pin 355 for details). Figure 2 , pin 355 is Figure 4 One end of the pin 355 located in the accommodating cavity 101 is used to electrically connect to the corresponding portion of the substrate 21 of the control circuit board 20 by welding (see Figure 9 ), one end of the pin 355 located outside the accommodating cavity 101 is used to electrically connect to the corresponding plug 40. The body of the connector 30 can be made of plastic material.

[0049] See also Figures 2 to 4In some embodiments, the connector 30 is provided corresponding to the printed circuit board 212. The connector 30 includes a plurality of legs 34, which are connected to corresponding portions of the substrate 21, more specifically, to the printed circuit board 212 of the substrate 21, via fasteners 341, 344, and 345. As previously described, the fasteners 341, 344, and 345 simultaneously secure the printed circuit board 212 of the substrate 21 to the bottom wall 121.

[0050] See also Figure 7 and Figure 9 The body of the connector 30 abuts against the inner surface 1102 of the upper shell 11. In some embodiments, the joint between the connector 30 and the upper shell 11 can be sealed with a sealant by dispensing, thereby preventing foreign matter from entering the accommodating cavity 101 through the gap at the joint between the connector 30 and the upper shell 11.

[0051] See also Figure 2 and Figure 9 In some embodiments, the inner surface 1102 of the upper shell 11 is provided with a plurality of clamping arms 111 extending inwardly. The plurality of clamping arms 111 are arranged around the opening 110 and engaged with the connector 30 to thereby locate the relative position of the connector 30 and the upper shell 11 .

[0052] Return to see Figure 3 The outer surface 1101 of the upper housing 11 is provided with a plurality of outwardly extending elastic arms 113, which are arranged, for example, on the same side of the opening 110. Each elastic arm 113 is provided with a wiring harness slot 1130, and each wiring harness slot 1130 allows the wiring harness 41 of a corresponding plug 40 from among the plurality of plugs 40 to pass through. The disclosed embodiment integrates multiple sockets 35 into a single connector 30, and arranges the plurality of wiring harness slots 1130, which guide the wiring harnesses 41 of the plurality of plugs 40, on the same side of the connector 30, thereby optimizing the layout of the controller 100 and the wiring harness 41.

[0053] See also Figures 5 to 9 In some embodiments, multiple elastic arms 113 are arranged side by side in a row, with at least some adjacent elastic arms 113 having overlapping portions. Opposite sides of the overlapping portions correspond to different wiring harness slots 1130 , which facilitates a compact structure for the multiple elastic arms 113 . In some embodiments, the wiring harness slots 1130 are staggered in a height direction perpendicular to the outer surface 1101 of the upper housing 11 , depending on the height of the plug 40 plugged into the receptacle 35 . This facilitates optimizing the layout of the multiple wiring harnesses 41 .

[0054] See also Figure 2 、 Figure 4 and Figure 9In some embodiments, the connector 30 includes a first support platform 31 and a second support platform 32, and the distance between the first support platform 31 and the bottom wall 121 of the metal lower shell 12 is greater than the distance between the second support platform 32 and the bottom wall 121 of the metal lower shell 12. That is, the first support platform 31 is farther away from the bottom wall 121 than the second support platform 32. The multiple sockets 35 include at least one first socket 351 arranged on the first support platform 31 and at least one second socket 352 arranged on the second support platform 32. In some embodiments, for example, two first sockets 351 are configured, corresponding to the power plug and the motor plug respectively. For example, four second sockets 352 are configured, corresponding to the central control plug, battery lock plug, taillight plug, and cadence plug respectively.

[0055] The electronic components 22 with a higher height can be arranged below the first support platform 31, and the electronic components 22 with a lower height can be arranged below the second support platform 32. In addition, the overall height of the first socket 351 on the first support platform 31 is higher, which allows the wire harness 41 of the plug 40 plugged into the first socket 351 to pass through the higher wire harness groove 1130. The overall height of the second socket 352 on the second support platform 32 is lower, which allows the wire harness 41 of the plug 40 plugged into the second socket 352 to pass through the lower wire harness groove 1130.

[0056] Continue to see Figure 2 、 Figure 4 and Figure 9 In some embodiments, the connector 30 includes a first recess 301 and a second recess 302. The bottom wall of the first recess 301 includes a first support platform 31, and the bottom wall of the second recess 302 includes a second support platform 32. The first recess 301 and the second recess 302 are recessed relative to the outer surface 1101 of the upper shell 11 toward the accommodating cavity 101, which not only utilizes the internal space of the accommodating cavity 101 but also makes the structure of the controller 100 more compact.

[0057] In some embodiments, the first recess 301 and the second recess 302 may be separated by a first partition 331. A second partition 332 may be provided within the first recess 301, protruding from the first support platform 31. A third partition 333 may be provided within the second recess 302, protruding from the second support platform 32. The provision of the first partition 331, the second partition 332, and the third partition 333 helps prevent large amounts of accumulated water from being stored in the first recess 301 and the second recess 302.

[0058] See also Figure 2 、 Figure 7 and Figure 9In some embodiments, the body of the connector 30 includes an annular abutment surface 361, an annular rib 362, and an annular groove 363. The annular abutment surface 361 abuts against the inner surface 1102 of the upper shell 11 and surrounds the opening 110. The annular rib 362 is located in the opening 110, and a gap is formed between the outer peripheral wall of the annular rib 362 and the peripheral wall of the opening 110. The annular groove 363 is located between the annular abutment surface 361 and the annular rib 362, and a portion of the annular groove 363 is covered by the inner surface 1102 of the upper shell 11. As a result, the upper shell 11 and the body of the connector 30 define an L-shaped gap at the opening 110, and the sealant can fill the L-shaped gap to achieve a sufficient seal at the connection between the upper shell 11 and the connector 30.

[0059] According to the controller 100 provided by the embodiments of the present disclosure, the high-heat-generating power device 221 is arranged on the metal substrate 211. The heat generated by the power device 221 can be directly transferred through the metal substrate 211 to the metal lower shell 12 for dissipation, thereby achieving excellent heat dissipation and effectively preventing overheating due to poor heat dissipation, which in turn shortens the lifespan of the key electronic components of the control circuit board 20. The joints between the upper shell 11 and the metal lower shell 12 are sealed with sealant, and the joints between the upper shell 11 and the connector 30 are also sealed with sealant, effectively preventing foreign matter from entering the accommodating cavity 101. The surface of the control circuit board 20 is covered with UV glue, which not only meets the protection requirements of the control circuit board 20 for waterproofing and corrosion resistance, but also does not significantly affect the heat conduction between the control circuit board 20 and the metal lower shell 12. Multiple sockets 35 are integrated into a single connector 30, and multiple harness slots 1130 that guide the harnesses 41 of multiple plugs 40 are arranged on the same side of the connector 30, optimizing the layout of the controller 100. The plurality of sockets 35 are arranged on the first support platform 31 and the second support platform 32 at different heights, and the plurality of harness slots 1130 are staggered in the height direction, thereby optimizing the layout of the harness 41 .
