Description

Technical Field

[0001] This utility model belongs to the field of automotive suspension control technology, and specifically refers to an automotive suspension control system. Background Technology

[0002] In existing active suspension technologies, rapid raising and lowering of the suspension is achieved by controlling the forward and reverse rotation of the motor through a controller, or by generating electricity through the forward and reverse rotation of the motor. However, existing motor controller products are large in size and contain a variety of components. They all adopt a multi-PCBA stacked design, including various control boards, drive power boards, structural boards, etc., which are connected by wiring harnesses or board-to-board connectors. Currently, this type of design has a complex assembly process, low production efficiency, high material and production costs, and a high risk of various failures.

[0003] In addition, most current technical solutions share the same heat dissipation system for power devices and motors, which means that the power capacity of the power devices cannot be fully utilized due to the influence of motor temperature. Low-power applications require the selection of high-cost, low-loss high-power devices, and the high material cost leads to a high system cost, which limits the market promotion of active suspension. Utility Model Content

[0004] This utility model provides a vehicle suspension control system, which mainly solves the problems of complex assembly, large number of circuit boards, large product size and poor heat dissipation in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A vehicle suspension control system, comprising: The upper housing has a mounting cavity; A drive control board is provided with multiple electrical interfaces. The drive control board is detachably mounted on the upper housing. The drive control board is provided with a power unit, which is located on the side of the drive control board away from the upper housing. The heat dissipation surface of the power unit abuts against the drive control board. A first heat dissipation protrusion is provided on the upper housing. The position of the first heat dissipation protrusion corresponds to the position of the power unit. The first heat dissipation protrusion is provided with a first heat dissipation surface, which abuts against the drive control board. The lower housing has a drive motor mounted on it. The lower housing is detachably connected to the upper housing. The drive control board is communicatively connected to the drive motor.

[0006] In some embodiments, the upper housing is provided with a first clearance groove, and the drive control board is provided with a first component unit. The first clearance groove corresponds to the position of the first component unit, and the first component unit is partially located in the first clearance groove.

[0007] In some embodiments, a heat dissipation module is also provided on the outer side of the upper housing. The heat dissipation module includes a plurality of spaced heat dissipation fins, which are disposed on the surface of the upper housing.

[0008] In some embodiments, a low-voltage interface and a high-voltage interface are also provided on the outside of the upper housing, both of which are electrically connected to the drive control board.

[0009] In some embodiments, a low-pressure adapter plate is also included in the mounting cavity of the upper housing. The low-pressure adapter plate has a plate-like structure, and the low-pressure interface is connected to the drive control board through the low-pressure adapter plate.

[0010] In some embodiments, the system also includes a resilient socket disposed on the drive control board and a first plug disposed on the lower housing. The first plug is electrically connected to the drive motor. When the upper housing is assembled onto the lower housing, the first plug is inserted into the resilient socket.

Simultaneously, a first heat dissipation protrusion with a first heat dissipation surface is provided on the upper housing. The position of the first heat dissipation protrusion corresponds to the position of the power unit, which is located on the side of the drive control board away from the upper housing. The first heat dissipation protrusion abuts against the drive control board, allowing the power unit to receive indirect heat dissipation through the drive control board, separate from the heat dissipation of the drive motor. This separates the heat dissipation from the drive motor, improving the heat dissipation efficiency of the power unit and preventing the drive motor temperature from affecting the power unit, thus maximizing the functionality of the power unit.

[0017] like Figure 1 and Figure 2 As shown, this utility model provides a vehicle suspension control system, which mainly includes an upper housing 100, a drive control board 105, and a lower housing 200.

[0018] Specifically, the upper housing 100 has a mounting cavity for mounting the drive control board 105. The drive control board 105 is detachably mounted on the upper housing 100 and has multiple electrical interfaces. These interfaces 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. In this embodiment, the drive control board 105 is secured using threaded holes and screws or bolts. A power unit 104 is connected to the drive control board 105. A first heat dissipation protrusion 101 is provided inside the upper housing 100. Figure 5As shown, the first heat dissipation boss 101 corresponds to the position of the power unit 104. A first heat dissipation surface is provided on the first heat dissipation boss 101, which abuts against the drive control board 105. The heat dissipation surface of the power unit 104 abuts against the drive control board. The heat conduction path of the power unit is indirectly dissipated through the drive control board and the first heat dissipation boss. The lower housing 200 is detachably connected to the upper housing 100. The specific connection method is to lock and fix it through a screw thread hole or through hole bolt nut structure. A drive motor 201 is provided in the lower housing 200. The drive control board 105 communicates with the drive motor 201, thereby realizing the forward and reverse rotation control of the drive motor 201 by the drive control board 105, realizing the lifting and lowering of the vehicle suspension. The specific lifting structure of the vehicle suspension is existing technology and will not be described in detail here.

[0019] This application solves the problem of complex assembly structures of multiple boards in the prior art by setting a highly integrated drive control board 105, which integrates multiple board modules that perform multiple functions on a single drive control board 105. At the same time, by setting a first heat dissipation boss 101 with a first heat dissipation surface, indirect heat dissipation of the power unit 104 located on the side of the drive control board away from the upper housing can be achieved. This separates the heat dissipation of the power unit 104 from the heat dissipation structure of the drive motor 201, allowing them to be handled separately. This improves heat dissipation efficiency and also avoids the large amount of heat generated by the drive motor 201 from affecting the power unit 104, thus maximizing the effectiveness of the power unit 104.

[0020] Furthermore, the power unit 104 is fixedly mounted on the drive control board 105 near the lower housing 200, such as... Figure 5 As shown, at this time, the heat dissipation surface of the power unit 104 abuts against the drive control board 105, and the first heat dissipation protrusion 101 abuts against the drive control board 105. The power unit 104 conducts heat to the outside of the housing 100 through the drive control board 105 and the first heat dissipation protrusion 101. Specifically, the power unit 104 is attached and fixed to the surface of the drive control board 105, and the power unit 104 is fixed to the drive control board 105 by pin soldering. During assembly, the power unit 104 and the drive control board 105 are assembled and fixed first, and then the drive control board 105 is fixed to the upper housing 100. In this embodiment, the power unit 104 is arranged in a two-row structure. Optionally, the power unit 104 can be in one row or three rows. Then, it is only necessary to set the size and position of the heat dissipation coverage area of ​​the first heat dissipation protrusion accordingly.

[0021] In one embodiment, a first clearance groove 102 is provided on the inner side of the upper housing 100, and a first component unit 1051 is provided on the drive control board 100. The position of the first clearance groove 102 corresponds to the position of the first component unit 1051, and a portion of the first component unit 1051 can be located within the first clearance groove 102. Specifically, as shown... Figure 5 As shown, the first component unit 1051 includes, but is not limited to, bus capacitors and common mode inductors, all of which protrude a certain height relative to the drive control board 105. In order to avoid these protruding first component units 1051 occupying the installation space of the drive motor 201 on the lower housing 200, the first component unit 1051 is set on the drive control board 105 on the side close to the upper housing 100. At the same time, a first clearance groove 102 is provided so that these protruding components are located in the first clearance groove 102, making the entire device installation structure compact and occupying a small volume.

[0022] Furthermore, such as Figure 4 As shown, a portion of the first component unit 1051 abuts against the first clearance groove 102, thereby allowing the heat generated by the first component unit 1051 to be directly discharged to the outside through the upper housing 100. Specifically, the contact surface of the first component unit 1051 is its heat dissipation surface protruding relative to the drive control board 105 in the height direction.

[0023] Furthermore, such as Figure 1 As shown, a heat dissipation module is also provided on the outer side of the upper housing 100. The heat dissipation module includes a plurality of spaced-apart heat dissipation fins 106 disposed on the outer surface of the upper housing 100. By setting the spaced-apart heat dissipation fins 106, heat exchange with the outside is accelerated, ensuring that the temperature rise of the power unit 104 operates within a reasonable range. In this embodiment, the heat dissipation fins 106 can be distributed laterally, longitudinally, or alternately on the outer surface of the upper housing 100, all of which can achieve uniform and rapid heat dissipation.

[0024] In one embodiment, a low-voltage interface 107 and a high-voltage interface 108 are provided on the outside of the upper housing 100. Both the low-voltage interface 107 and the high-voltage interface 108 are electrically connected to the drive control board 105. The low-voltage interface 107 can be connected to an external low-voltage power supply, and the high-voltage interface 108 can be connected to an external high-voltage power supply.

[0025] In one embodiment, to reduce the volume occupied by the upper housing 100 and the overall space occupied by the device, a low-voltage adapter plate 103 is provided in the mounting cavity of the upper housing 100. The low-voltage adapter plate 103 is connected to an external low-voltage interface 107 and is also connected to the drive control board 105. In this embodiment, the low-voltage adapter plate 103 is a thin plate structure and is arranged parallel to the drive control board 105, thereby reducing the mounting space of the upper housing 100 in the plane perpendicular to the drive control board 105 and further reducing the volume of the upper housing 100.

[0026] In one embodiment, the drive control board 105 is provided with a flexible socket 1052, such as Figure 3 As shown, a corresponding first plug 203 is provided on the lower housing 200. The drive motor 201 is electrically connected to the first plug 203. The elastic socket 1052 has a Y-shaped structure, which can guide the first plug 203 during the insertion process. The first plug 203 and the elastic socket 1052 are in corresponding positions. When the upper housing 100 is installed on the lower housing 200, the first plug 203 located in the lower housing 200 can be directly inserted into the elastic socket 1052, realizing blind insertion of the first plug 203, thereby realizing the electrical connection between the drive control board 105 and the drive motor 201.

[0027] In one embodiment, such as Figure 2 As shown, the system also includes an encoder board 204 disposed within the lower housing 200. The drive control board 105 is electrically connected to the drive motor 201 via the encoder board 204. A first cover plate 202 is provided on the side of the lower housing 200 near the encoder board 204. The first cover plate 202 is detachably connected to the lower housing 200. The detachable connection method of the first cover plate 202 includes, but is not limited to, threaded hole screw structure, nut, or through hole structure. By providing the first cover plate 202, the installation and maintenance of the encoder board 204 can be facilitated.

[0028] In one embodiment, the drive control board 105 has a high-voltage region, and the power unit 104 is disposed near the high-voltage region side of the drive control board 105. By placing the power unit 104 on the high-voltage region side, only basic insulation from the low-voltage power supply (flyback power supply) and communication circuits is required; most other circuits only require functional insulation, significantly reducing the board space. Compared to basic insulation, functional insulation has lower requirements for electrical clearances and creepage distances, allowing for a more compact board layout and further reducing board space.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model. These improvements and modifications should also be considered within the scope of protection of this utility model.
