[0030] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation manners.

[0031] As Figure 1 shown, the present utility model provides a technical solution: a highly reliable wireless controller, including:

[0032] A heat dissipation base 16, inside which a power aluminum substrate 18 is arranged. Vertically arranged on the top of the power aluminum substrate 18 is a power cord wiring seat 17, and horizontally arranged on the top of the power aluminum substrate 18 is a phase wire wiring seat 25.

A socket strip 22 is arranged on the top of the circuit control board 21. Inside the heat dissipation base 16, an end cover 1 is arranged above the circuit control board 21. On the top of the end cover 1, first through groove 5, second through groove 11 and third through groove 26 are opened for the phase wire wiring seat 25, power cord wiring seat 17 and socket strip 22 to expose from the top of the end cover 1 respectively;

[0033] A phase line cover plate 6 for shielding the first through groove 5 is embedded at the top of the end cover 1. A plurality of avoidance grooves 61 are formed on one side of the phase line cover plate 6 close to the third through groove 26. Phase line guiding grooves 4 are longitudinally formed at positions corresponding to the plurality of avoidance grooves 61 on the top of the end cover 1. An arc-shaped clamping plate 2 is arranged on one side of the top of the end cover 1. A motor wire harness assembly 24 is arranged inside the arc-shaped groove 201 of the arc-shaped clamping plate 2. Phase line connection terminals 241 of the phase lines in the motor wire harness assembly 24 respectively pass through the phase line guiding grooves 4 and the avoidance grooves 61 in sequence and are connected to a phase line connection base 25. A Hall plug 242 of the motor wire harness assembly 24 is connected to a socket 22. A power supply cover plate 14 for shielding the second through groove 11 is embedded at the top of the end cover 1. An arc-shaped groove 10 is formed on the other side of the top of the end cover 1. A pressing plate 15 extends from the top of the power supply cover plate 14. An arc-shaped pressing groove 151 is formed at a position corresponding to the arc-shaped groove 10 at the bottom of the pressing plate 15. A vehicle main wire signal wire harness assembly 13 is arranged between the arc-shaped pressing groove 151 and the arc-shaped groove 10. A functional wire plug 131 of the vehicle main wire signal wire harness assembly 13 is connected to the socket 22. A plurality of wire grooves 142 are formed on the side wall of the power supply cover plate 14. Power supply connection terminals 12 connected to a power supply connection base 17 are placed inside the plurality of wire grooves 142. This design ensures that the motor wire harness assembly 24 is stuck inside the arc-shaped groove 201 of the arc-shaped clamping plate 2, preventing the motor wire harness assembly 24 from swinging left and right. At the same time, the phase lines in the motor wire harness assembly 24 pass through the avoidance grooves 61 of the phase line cover plate 6 along the phase line guiding grooves 4, and the phase line connection terminals 241 of the phase lines in the motor wire harness assembly 24 are stuck inside the phase line guiding grooves 4, thereby limiting the phase line connection terminals 241 of the phase lines in the motor wire harness assembly 24, reducing the risk of loosening at the connection between the phase line connection terminals 241 of the phase lines in the motor wire harness assembly 24 and the phase line connection base 25 due to the motor wire harness assembly 24 attempting to swing, thus avoiding the phenomenon of abnormal operation of the phase-loss motor caused by loosening and improving the reliability during use. By passing the power supply connection terminals 12 through the wire grooves 142 of the power supply cover plate 14, the wire grooves 142 limit the power supply connection terminals 12, avoiding loosening at the connection between the power supply connection terminals 12 and the power supply connection base 17 and improving the reliability during use. At the same time, the arc-shaped pressing groove 151 on the pressing plate 15 cooperates with the arc-shaped groove 10 to tightly limit the vehicle main wire signal wire harness assembly 13, avoiding the phenomenon of loosening at the connection between the functional wire plug 131 and the socket 22 due to the swinging of the vehicle main wire signal wire harness assembly 13 and improving the reliability during use.

[0034] Refer to Figure 1 and Figure 5, a second compression bolt 243 is provided between the phase wire connection terminal 241 of the 24-phase wires in the motor harness assembly 24 and the phase wire connection seat 25, a first compression bolt 121 is provided between the power wire connection terminal 12 and the power wire connection seat 17, and a fixing bolt 152 is provided between the pressing plate 15 and the heat dissipation base 16. The phase wire connection terminal 241 of the phase wires in the motor harness assembly 24 matches the phase wire guiding groove 4, and the power wire connection terminal 12 matches the wire groove 142. This design improves the stability between the phase wire connection terminal 241 of the phase wires in the motor harness assembly 24 and the phase wire connection seat 25, and between the power wire connection terminal 12 and the power wire connection seat 17 by using the first compression bolt 121 and the second compression bolt 243, avoids loosening at the connection, and improves the reliability during use.

[0035] Referring to Figure 1 , Figure 2 and Figure 6 , a pair of stop blocks 63 are symmetrically provided on the opposite side walls of the phase wire cover plate 6, and at the position inside the end cover 1 corresponding to the stop blocks 63, there is a stop slot 104 that matches the stop blocks 63. A pair of clamping blocks 141 are symmetrically provided on the opposite side walls of the power wire cover plate 14, and at the position inside the end cover 1 corresponding to the clamping blocks 141, there is a clamping slot 9 that matches the clamping blocks 141. This design clamps the phase wire cover plate 6 on the end cover 1 by using the cooperation of the stop blocks 63 and the stop slots 104, and then limits the phase wires in the motor harness assembly 24 through the cooperation of the avoidance slot 61 and the phase wire guiding groove 4, improving the stability of the limit and avoiding the swinging of the phase wires in the motor harness assembly 24. By using the cooperation of the pressing block and the pressing slot, the power wire cover plate 14 is clamped on the end cover 1, improving the stability of the pressing and limiting of the vehicle main wire signal harness assembly 13 by the arc-shaped pressing groove 151 on the pressing plate 15 and the arc-shaped groove 10, thus ensuring that the functional wire plug 131 will not loosen due to vehicle bumps, and further improving the reliability during use.

[0036] Referring to Figure 1 and Figure 7 , a limiting groove 3 communicating with the phase wire guiding groove 4 is horizontally opened at the top of the end cover 1. The lower side of the inner wall of the limiting groove 3 is higher than the lower side of the inner wall of the phase wire guiding groove 4. The side wall of the phase wire cover plate 6 is an inclined surface and is provided with a limiting plate 62 placed inside the limiting groove 3. The limiting plate 62 fits with the limiting groove 3, and the avoidance slot 61 extends through to the side wall of the limiting plate 62. This design limits the inclined surface of the side wall of the phase wire cover plate 6 by using the cooperation of the limiting plate 62 and the limiting groove 3, avoids the phase wire cover plate 6 from tilting, and further restricts the swinging of the phase wires in the motor harness assembly 24.

[0037] Referring to Figure 1 , Figure 3 and Figure 4A positioning pin 19 is provided on the top of the power aluminum substrate 18 and is placed below the circuit control board 21. A positioning socket 23 is provided on the top of the circuit control board 21. The positioning pin 19 penetrates the circuit control board 21 and is connected to the positioning socket 23. This design facilitates the positioning and installation of the circuit control board 21 by connecting the positioning pin 19 with the positioning socket 23, while preventing the circuit control board 21 from shifting.

[0038] Reference Figure 1 , Figure 4 and Figure 9 A plurality of fastening screws 181 are arranged between the power aluminum substrate 18 and the heat dissipation base 16, a plurality of extension columns 105 are symmetrically arranged at the bottom of the end cover 1, a connecting bolt 211 is arranged between the circuit control board 21 and the extension column 105, and a plurality of connecting bolts 102 are arranged between the end cover 1 and the heat dissipation base 16, wherein the power aluminum substrate 18 and the heat dissipation base 16 are connected by the fastening screws 181 with insulating gaskets. The design improves the stability of the connection between the power aluminum substrate 18 and the heat dissipation base 16 by using fastening bolts, improves the stability of the connection between the circuit control board 21 and the extension column 105 by using connecting bolts 211, and fastens the end cover 1 and the heat dissipation base 16 by using connecting bolts 102, thereby preventing the circuit control board 21 from moving in the vertical direction, and coordinating with the positioning pin 19 and the positioning socket 23 to position the circuit control board 21, thereby preventing the circuit control board 21 from shifting in the horizontal, longitudinal and vertical directions, and improving the stability of the installation of the circuit control board 21.

[0039] Reference Figure 7 A U-shaped plate 101 is extended from the side wall of the end cover 1, and the upper end surface of the U-shaped plate 101 is lower than the upper end surface of the heat dissipation base 16. A U-shaped sealing groove 27 is formed between the U-shaped plate 101 and the inner wall of the heat dissipation base 16, and a sealing rubber layer is arranged inside the U-shaped sealing groove 27. This design provides a sealing rubber layer inside the U-shaped sealing groove 27 formed at the connection between the U-shaped plate 101 and the heat dissipation base 16, thereby sealing the connection between the heat dissipation base 16 and the end cover 1, thereby achieving a waterproof sealing effect.

[0040] Reference Figure 6 and Figure 9 A mounting groove 103 is provided on the top of the end cover 1. A ventilation hole 8 is provided on the top of the end cover 1 and is through and disposed inside the mounting groove 103. A ventilation valve cover 7 is provided inside the mounting groove 103. The ventilation valve cover 7 fits tightly with the mounting groove 103. This design uses the ventilation hole 8 to discharge the high-temperature expanded gas inside the controller. The gas is discharged through the ventilation valve cover 7 to ensure that other sealing positions will not be damaged by the expanded gas. By making the ventilation valve cover 7 fit tightly with the mounting groove 103, the sealing of the connection is improved, thereby achieving a waterproof sealing effect.

[0041] ReferenceFigure 1 and Figure 8 On the side wall of the heat dissipation base 16, a plurality of first heat dissipation ribs 161 are evenly distributed. A heat dissipation groove 163 is formed at the bottom of the heat dissipation base 16. A plurality of second heat dissipation ribs 162 are arranged inside the heat dissipation groove 163. This design evenly distributes the first heat dissipation ribs 161 on the side wall of the heat dissipation base 16. While increasing the total heat dissipation area, due to the characteristic that heat transfers from high to low, the heat dissipated by the heat source will continuously transfer to the surrounding of the housing, causing the heat to accumulate and concentrate on the side wall rather than the bottom, thereby improving the heat dissipation efficiency.

[0042] Refer to Figure 1 and Figure 4 For, the materials of the power aluminum substrate 18 and the heat dissipation base 16 are both aluminum alloy. This design is because the high-power MOS transistor 20 is the main source of heat generation. The power aluminum substrate 18 and the die-cast aluminum alloy heat dissipation base 16 are made of the same material, and the contact surface between the two is relatively large, so the heat transfer efficiency will be greatly accelerated, thereby improving the heat dissipation efficiency.

[0043] Refer to Figures 1 - 9 As an embodiment of the present utility model: The staff clips the motor harness integration 24 in the arc-shaped groove 201 of the arc-shaped clamping plate 2 to ensure that the motor harness integration 24 does not swing left and right. At the same time, the phase wires in the motor harness integration 24 are along the phase wire guiding groove 4, and the phase wire connection terminals 241 in the motor harness integration 24 are clamped inside the phase wire guiding groove 4, so as to limit the phase wire connection terminals 241 in the motor harness integration 24. And connect the phase wire connection terminal 241 with the phase wire connection base 25 through the second compression bolt 243, thereby reducing the risk that the connection between the phase wire connection terminal 241 in the motor harness integration 24 and the phase wire connection base 25 becomes loose due to the attempt of the motor harness integration 24 to swing, thus avoiding the phenomenon that the abnormal motor caused by the looseness may occur, and improving the reliability during use. Then insert the Hall plug 242 into the inside of the socket 22. Finally, apply force to the phase wire cover plate 6 so that the stop block 63 cooperates with the stop slot 104. At this time, the limiting plate 62 is placed inside the limiting groove 3 to prevent the phase wire cover plate 6 from warping. Thus, the phase wire cover plate 6 is clamped on the end cover 1. Thereby, the phase wires in the motor harness integration 24 are limited by the cooperation of the avoidance groove 61 and the phase wire guiding groove 4, improving the stability of the limit and avoiding the phase wires in the motor harness integration 24 from swinging, further improving the reliability during use;

[0044] Next, connect the power supply line connection terminal 12 and the power supply line terminal block 17 through the first compression bolt 121. Make the bottom of the vehicle main wire signal harness assembly 13 fit against the arc-shaped groove 10 and connect the functional wire plug 131 with the socket strip 22. Finally, apply force to the power supply cover plate 14 so that the compression block cooperates with the compression groove, thereby clamping the power supply cover plate 14 on the end cover 1. Then, use the fixing bolt 152 to fix the connection between the compression plate 15 and the end cover 1. At this time, the arc-shaped compression groove 151 on the compression plate 15 cooperates with the arc-shaped groove 10 to compress and limit the vehicle main wire signal harness assembly 13, avoiding the loosening of the connection between the functional wire plug 131 and the socket strip 22 caused by the swing of the vehicle main wire signal harness assembly 13. Thus, it is ensured that the functional wire plug 131 will not loosen due to vehicle bumps, improving the reliability during use. At the same time, the wire groove 142 limits the power supply line connection terminal 12, avoiding the loosening of the connection between the power supply line connection terminal 12 and the power supply line terminal block 17, and improving the reliability during use.

[0045] By evenly distributing the first heat dissipation ribs 161 on the side wall of the heat dissipation base 16, while increasing the total heat dissipation area, due to the characteristic that heat transfers from high to low, the heat dissipated by the heat source will continuously transfer to the surrounding of the housing, causing the heat to accumulate and concentrate on the side wall and flow out from the multiple first heat dissipation ribs 161 instead of the bottom, thereby improving the heat dissipation efficiency. At the same time, since the high-power MOS transistor 20 is the main source of heat generation, the power aluminum substrate 18 and the die-cast aluminum alloy heat dissipation base 16 are made of the same material and have a large contact surface, so the heat transfer efficiency will be greatly accelerated, further improving the heat dissipation efficiency and enhancing the practicability of the present invention.
