Description

Technical Field

[0001] This utility model belongs to the field of motor control technology for automotive suspension systems, and specifically refers to a wind-cooled heat dissipation upper shell and control device. Background Technology

[0002] In existing suspension control technologies, motor controllers often share a cooling system with the motor. To ensure the power devices can operate at their full potential, the distance between these devices needs to be increased, resulting in a large electronic controller and consequently a large and costly overall suspension system. Furthermore, existing solutions employ a multi-PCBA stacked design, with overlapping PCBAs in the vertical space. This prevents non-inductive components such as bus capacitors and common-mode inductors from utilizing their housings for heat dissipation, leading to large and costly common-mode inductors and bus capacitors. Moreover, existing technologies have complex electromagnetic compatibility (EMC) designs, failing to meet the EMC requirements of vehicle manufacturers. Utility Model Content

[0017] The present application will be further described in detail below with reference to the accompanying drawings. In the description of the embodiments, unless otherwise stated, the terms "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the present application must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present application.

[0018] like Figure 1 As shown, this utility model provides a wind-cooled heat dissipation upper shell, which mainly includes a shell body 100, a heat dissipation module, and multiple heat dissipation surfaces. The shell body 100 has a mounting position for mounting a power board 300. The heat dissipation module is set on the outside of the shell body 100. The heat inside the shell body 100 is dissipated to the outside through the shell body 100 itself and the heat dissipation module. The main heat comes from the power unit module and other component units. Multiple heat dissipation surfaces are spaced apart on the inside of the shell body 100, and the positions of the multiple heat dissipation surfaces correspond to the positions of the heat dissipation module.

[0019] In this embodiment, a heat dissipation module is provided on the outside of the housing body 100, and multiple heat dissipation surfaces are provided on the inside of the housing body 100. The heat dissipation surfaces correspond to the positions of the heat dissipation module, enabling the power unit 303 and other component units installed inside the housing body 100, such as the bus capacitor 302 and common-mode inductor 301, to contact the heat dissipation surfaces. Figure 3 and Figure 5 As shown, this allows the heat generated to be quickly dissipated to the outside through the heat dissipation surface and heat dissipation module, separating the heat dissipation of the motor from that of the power element 303 and other components, and allowing for separate heat dissipation, thus maximizing the function of the power unit 303.

[0020] In one embodiment, the heat dissipation module is air-cooled, and the heat dissipation module includes a plurality of spaced-apart heat dissipation fins 108, such as... Figure 2 As shown, the heat dissipation fins 108 are integrally formed with the housing body 100, and the heat dissipation fins 108 are as follows: Figure 2 The distribution in the left and right directions shown, or as follows Figure 2 The heat dissipation fins 108 are distributed vertically as shown; or, the heat dissipation fins 108 are distributed in a grid pattern. It can be understood that the shape and arrangement of the heat dissipation fins 108 are not limited by this utility model, and the purpose of the heat dissipation module can be achieved simply by using air cooling.

[0021] In one embodiment, to make room for the control motor inside the lower housing 200, thereby making the overall device compact and saving installation space, a plurality of first clearance slots 101 are provided on the inner side of the housing body 100, and the plurality of first clearance slots 101 are set at a preset depth. Specifically, in this embodiment, the housing body 100 itself has a certain thickness, so it is possible to make holes inside the housing body 100 to make room. The plurality of first clearance slots 101 are set at different depths to meet the installation clearance of components of different heights. For example, the bus capacitor 302 and the common mode inductor 301 protrude a certain height from the power board 300, and the height of the protrusion is different. Therefore, the depths of the two first clearance slots 101 are not consistent. When the power board 300 is installed on the mounting position of the housing body 100, the bus capacitor 302 and the common mode inductor 301 can be located exactly in the two first clearance slots 101, avoiding component interference, and at the same time saving a lot of space for the lower housing 200.

[0022] Furthermore, the heat dissipation surface includes a first heat dissipation surface 1011 and a second heat dissipation surface 102. The first heat dissipation surface 1011 is located within the first clearance groove 101, and the second heat dissipation surface 102 is disposed inside the housing body 100 and offset relative to the first clearance groove 1011. A preset distance is set between the edge of the second heat dissipation surface 102 and the edge of the first clearance groove 101, thereby facilitating the installation of the power unit 303. The first heat dissipation surface 1011 located within the first clearance groove 101 allows relatively protruding components located on one side of the power board 300, such as the bus capacitor 302 and the common mode inductor 301, to contact the first heat dissipation surface 1011, achieving heat dissipation for these components, saving space in the housing 200 while improving heat dissipation efficiency.

[0023] In one embodiment, the outer side of the housing body 100 is provided with a high-voltage connector 107, a low-voltage connector 103, and a grounding point 105. The high-voltage connector 107 enables connection to an external high-voltage plug, and the low-voltage connector 103 enables connection to an external low-voltage plug. Both the high-voltage and low-voltage connectors are electrically connected to the power board. For example, the high-voltage connector is connected to the high-voltage area unit of the power board, and the low-voltage connector is connected to the low-voltage area unit of the power board. The grounding point 105 can be connected to an external grounding wire, thus realizing the grounding setting of the entire device.

[0024] In one embodiment, a plurality of protruding baffles 103 are provided on the inner side of the housing body 100. The baffles 103 protrude a certain height relative to the inner wall of the housing body 100, so that the plurality of baffles 103 divide the interior of the housing body 100 into a plurality of independent first cavities, wherein the baffles 103 are made of metal material.

[0025] like Figure 1 and Figure 4 As shown, in this embodiment, the first cavity includes a transformer area 1042, a high-voltage area 1041, a low-voltage area 1043, and a power unit area. By implementing a special separate cavity design inside the housing body 100, electromagnetic interference spatial coupling between the high-voltage area 1041, the low-voltage area 1043, the power unit area, and the transformer area 1042 is avoided. To enhance the shielding effect of the cavities, the baffle wall 103 is made of metal materials, such as aluminum, cast iron, or other metal materials. Each cavity forms a closed cavity from the baffle wall protruding from the inner wall of the housing body 100, and each first cavity is independent and not connected to each other.

[0026] Furthermore, in order to achieve a better electrical connection between the power board 300 and the retaining wall 103, a number of first connection points 1031 are provided on the retaining wall 103 at intervals for electrical connection with the power board 300.

[0027] In one embodiment, such as Figure 6As shown, this utility model also provides a control device, mainly used for the automated control of automobile suspension lifting. It mainly includes the air-cooled heat dissipation upper shell, power board 300, power unit 303, and lower shell as described in the above embodiments. The power board 300 has a first component unit that protrudes a certain height relative to itself. The first component unit corresponds to the first clearance groove 101 and abuts against the first heat dissipation surface 1011 to achieve heat conduction. In this embodiment, the first component unit includes, but is not limited to, components such as bus capacitor 302 and common-mode inductor 301 that protrude a certain height relative to the power board. In this embodiment, the power board 300 has multiple electrical interfaces that can be connected to the vehicle's low-voltage and high-voltage systems, to various motor signal acquisition signals, and to various oil temperature and oil pressure signal acquisition signals.

[0028] The power unit 303 is detachably mounted on the second heat dissipation surface 102. In this embodiment, the second heat dissipation surface 102 is a boss that protrudes to a certain height relative to the interior of the housing body 100. Mounting holes are provided on the boss, and matching through holes are provided on the power unit 303. It is then secured with screws. When installing the power board 300, the power unit 303 is first fixed to the second heat dissipation surface 102, and the heat dissipation surface of the power unit 303 contacts and abuts against the second heat dissipation surface 102, thereby achieving heat dissipation of the power unit 303. By making the power unit 303 detachable relative to the housing body 100, the installation of the power board 300 and the power unit 303 are distributed, avoiding damage to the power unit 303 during the installation of the power board 300. Multiple connection holes are provided on the power board 300, and multiple pins are provided on the power unit 303. The positions of the multiple pins correspond to the positions of the connection holes, and the multiple pins are inserted into the connection holes. The pins are fixed by soldering to realize the electrical connection between the power unit 303 and the power board 300.

[0029] The lower housing 200 is detachably connected to the housing body 100. A cavity is provided on the lower housing 200, and a control motor is housed within the cavity. The control motor is electrically connected to the power board 300. Specifically, an elastic insert is provided on the side of the power board 300 near the lower housing 200, and a corresponding plug is provided inside the lower housing 200. When connecting the lower housing 100 to the housing body 100 of the upper housing, the plug is blind-plugged into the elastic insert. Corresponding threaded fixing holes and positioning structures are provided on both the housing body 100 and the lower housing 200, and assembly between the housing body 100 and the lower housing 200 is achieved using bolts.

[0030] In one embodiment, a plurality of second connection points are provided on the power board 300. The number of second connection points is the same as the number of first connection points 1031, and their positions correspond. The plurality of first connection points 1031 and the plurality of second connection points are connected one-to-one to realize the conduction of various components on the power board 300.

[0031] In one embodiment, such as Figure 4 As shown, the power board 300 is provided with a high-voltage area, a low-voltage area, a power unit area, and a transformer area.
