Another aspect of this invention provides a control device for a vehicle suspension hydraulic pump.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The upper housing has a first mounting position and a second mounting position.

[0014] In some embodiments, the upper housing is provided with a first positioning post, and the control base plate is provided with a first positioning hole, the first positioning post and the first positioning hole being positioned corresponding to each other.

[0015] In some embodiments, the control base plate is provided with a high-voltage unit and a low-voltage unit. The high-voltage unit is located in the middle section of the control base plate, and the low-voltage units are located at both ends of the control base plate. The power unit is located close to the high-voltage unit.

[0016] In some embodiments, a heat dissipation structure is provided on the outer side of the upper housing, the heat dissipation structure including a plurality of heat dissipation fins, the plurality of heat dissipation fins being evenly distributed on the outer side of the upper housing.

[0033] 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.

[0034] like Figure 1-4 As shown, this utility model provides a control and adjustment component and a vehicle suspension hydraulic pump control device. The vehicle suspension hydraulic pump control device mainly includes a lower housing 100, an upper housing 200, a power unit 101, and a control base plate 102. A first installation space is provided on the lower housing 200, and a hydraulic pump 201 is installed in the first installation space for hydraulic adjustment of the suspension. The upper housing 100 is detachably mounted on the lower housing 200. When the upper housing 100 and the lower housing 200 are connected and fixed, the upper housing 100 can seal the first installation space of the lower housing 200. Specifically, a third fixing hole 107 is provided on the upper housing 100, and a corresponding third through hole is provided on the lower housing 200. A third positioning post and a third positioning hole 1071 are respectively provided on the upper housing 100 and the lower housing 200. The upper housing 100 is positioned when installed on the lower housing 200, and the upper housing 100 and the lower housing 200 are fixed by screws or bolts. The upper housing 100 is provided with a first mounting position 105 and a second mounting position 106; the first mounting position 105 is used for mounting the power unit 101, and the second mounting position 106 is used for mounting the control base plate 102.

[0035] Specifically, multiple communication pins 1011 are provided on the power unit 101. When the power unit 101 is installed on the first mounting position 105 and the upper housing 100 is fixedly connected to the lower housing 200, the multiple communication pins 1011 extend to the side of the lower housing 200, and the communication pins 1011 have a preset length. Multiple communication sockets 1025 are provided on the control base plate 102. The number of communication pins 1011 matches the number of communication sockets 1025, and the positions of the communication pins 1011 and the positions of the communication sockets 1025 correspond one-to-one. During installation, the communication pins 1011 are inserted into the communication sockets 1025 and soldered to ensure the stability of the connection and transmission. Through the insertion of the communication pins 1011 and the communication sockets 1025, the communication connection between the power unit 101 and the control base plate 102 is realized.

[0036] The control base plate 102 houses various circuits, such as drive circuits and sampling circuits, consolidating the circuitry of multiple circuit boards in the prior art onto a single control base plate 102. The control base plate 102 is detachably mounted on the second mounting position 106 of the upper housing 100. The control base plate 102 and the hydraulic pump 201 are communicatively connected, enabling adaptive adjustment of the hydraulic pump 201 through the control base plate 102. It is particularly noteworthy that when the power unit 101 is mounted on the control base plate 102, a preset distance is maintained between the power unit 101 and the control base plate 102. The power unit 101 transmits signals to the control base plate 102 via communication pin 1011. This preset distance allows the power unit 101 to occupy less space on the control base plate 102, thus providing more space on the control base plate 102 for circuit layout and component placement, enabling the high integration of multiple functional circuits onto the control base plate 102.

[0037] Furthermore, a high-voltage unit and a low-voltage unit are arranged on the control base plate 102. The low-voltage unit is located near both ends of the control base plate 102, while the high-voltage unit is located in the middle section of the control base plate 102. The power unit 101 is located near the high-voltage unit. In this case, only basic insulation from the low-voltage power supply (flyback power supply) and communication circuit is required, while most other circuits only require functional insulation, which greatly reduces the board space required for the control base plate 102. Compared with basic insulation, functional insulation has lower requirements for electrical clearance and creepage distance, allowing for a more compact board layout and thus reducing board space. In addition, the power unit 101 is directly mounted on the upper housing 100, avoiding the need for a separate power board to be mounted on the assembly housing.

[0038] By adopting the above structure, the circuit layout and wiring are optimized, thereby realizing the modular integrated board design. The interface board, control board, driver board and power board in the existing technology are integrated into one board, realizing the high integration requirement of the control baseboard 102 circuit, thereby simplifying the assembly process, reducing the number of parts, reducing assembly difficulty and saving costs.

[0039] In one embodiment, a first mounting platform is provided on the upper housing 100, and a first mounting hole 1051 is provided on the first mounting platform to form a first mounting position 105. Specifically, a corresponding first fixing hole is provided on the power unit 101, and the first fixing hole corresponds to the position of the first mounting hole 1051. The power unit 101 is locked and fixed on the first mounting platform by screws. In this embodiment, as shown... Figure 3 and Figure 4 As shown, the first mounting platform has a certain area, thereby providing a support for the power unit 101. In this embodiment, there are two first mounting platforms, which are used to fix two power units 101. The two power units 101 control two hydraulic pumps 201. In actual operation, the number of power units 101 and hydraulic pumps 201 is determined according to actual needs, and their number is not limited in this utility model.

[0040] Furthermore, a second mounting platform is provided on the upper housing 100, and a second mounting hole 1061 is provided on the second mounting platform to form a second mounting position 106. A first height difference is provided between the second mounting platform and the first mounting platform so that a preset distance is formed between the power unit 101 and the control base plate 102 after they are installed and fixed. Specifically, the second mounting platform is supported by a plurality of spaced-apart bosses arranged along the edge of the upper housing 100. The plurality of bosses are on the same horizontal plane. A plurality of second fixing holes 1021 are provided on the control base plate 102, and the positions of the plurality of second fixing holes 1021 correspond to the plurality of second mounting holes 1061. The control base plate 102 is fixed to the second mounting platform of the upper housing 100 by screws. To facilitate assembly, a certain distance is provided between the edge of the control base plate 102 and the inner wall of the upper housing 100.

[0041] Furthermore, a first positioning post 1062 is provided on the upper housing 100, and a first positioning hole 1022 is provided on the control base plate 102. The positions of the first positioning post 1062 and the first positioning hole 1022 correspond. In this embodiment, the first positioning post 1062 is positioned close to the second mounting hole 1061, and the number of first positioning posts 1062 and first positioning holes 1022 matches. In order to facilitate positioning, the number of first positioning posts 1062 is not less than two. Optionally, the first positioning post 1062 can also be provided on the control base plate 100, and the first positioning hole 1022 can be provided on the upper housing 100, which can also achieve the installation and positioning of the control base plate 102.

[0042] In one embodiment, to facilitate heat dissipation for the circuit components of the power unit 101 and the control base plate 102, a heat dissipation structure 103 is provided on the outer side of the upper housing 101. The heat dissipation structure 103 includes multiple heat dissipation fins, which are evenly distributed on the outer side of the upper housing 101. The power unit 101 relies on the upper housing 100 for natural heat dissipation. The power unit 101 is bolted to the upper housing 100 using a high thermal conductivity material. The top of the upper housing 100 is designed with heat dissipation fins to increase the heat dissipation area. At the same time, the fins are evenly distributed, resulting in uniform heat dissipation. While achieving natural heat dissipation, it also makes the temperature rise of the two power units 101 in this application similar.

[0043] Alternatively, the structure of the heat dissipation fins can be changed to a structure of multiple evenly spaced heat dissipation columns, with one end of each column flush with the heat dissipation fins in this embodiment, which can also achieve the effect of natural heat dissipation.

[0044] In one embodiment, to avoid excessive and complex wiring connections between the control base plate 102 and the hydraulic pump 201, such as... Figure 6 and Figure 7 as well as Figure 8 As shown, a flexible terminal 1027 is provided on the control base plate 102, and a connecting plug 2012 is provided on the hydraulic pump 201. The position of the connecting plug 2012 corresponds to the position of the flexible terminal 1027. When the upper housing 100 is installed on the lower housing 200, the connecting plug 2021 is inserted into the flexible terminal 1027, realizing blind insertion between the control base plate 102 and the control end of the hydraulic pump 201, simplifying the assembly process. Specifically, as shown... Figure 6 and Figure 7 As shown, the elastic terminal 1027 consists of two gripper structures with elastic clamping force. The insertion end of the elastic terminal 1027 is an arc-shaped guide structure. When one end of the connecting plug 2012 abuts against the insertion end of the elastic terminal 1027, the arc-shaped guide structure guides the connecting plug 2012 into the elastic terminal 1027. The elastic terminal 1027 clamps and fixes the connecting plug 2012 with its elastic clamping force. By adopting the above structure, the difficulty of blindly inserting the elastic terminal 1027 and the connecting plug 2012 is reduced. In this embodiment, there are three elastic terminals 1027 and three connecting plugs 2012. It can be understood that the number of elastic terminals 1027 and the number of connecting plugs 2012 are not limited by this utility model, and the corresponding number can be set according to actual operational needs.

[0045] Furthermore, to simplify the wiring and assembly process, such as Figure 7 and Figure 8As shown, a first connector 1026 is provided on the side of the control base plate 102 near the lower housing 200, and a terminal block assembly 2011 is provided on the hydraulic pump 201. One end of the terminal block assembly 2011 can be plugged into or detached from the first connector 1026. In actual assembly, before blindly inserting the flexible terminal 1027 and the connecting connector 2012, the terminal block assembly 2011 and the first connector 1026 are connected first.

[0046] In one embodiment, to facilitate the connection of the device to an external power source, a high-voltage connector 1042 and a low-voltage connector 1041 are provided on the outside of the upper housing 100. The high-voltage connector 1042 is electrically connected to the high-voltage unit of the control base plate 102, and the low-voltage connector 1041 is electrically connected to the low-voltage unit of the control base plate 102, thereby realizing power supply. At the same time, the provision of the high-voltage connector 1042 and the low-voltage connector 1041 can effectively simplify the connection method between the control device assembly and the external power source, and facilitate assembly.

[0047] In one embodiment, a first clearance groove 108 is provided on the upper housing 100, and the position of the first clearance groove 108 corresponds to the position of the heat sink fins. By providing the first clearance groove 108, components mounted on the control base plate 102 can be repositioned, such as... Figure 5 and Figure 6 As shown, the common-mode inductor 1023 and bus capacitor 1024 are disposed on the control base plate 102. In this embodiment, the common-mode inductor 1023 is disposed on one side of the upper housing 100, and a first clearance groove 108 is provided at the corresponding position on the upper housing 100 for clearance. The bus capacitor 1024 is disposed on one side of the lower housing. Due to its relatively large size, a clearance structure is provided on the lower housing for clearance. Optionally, the common-mode inductor 1023 and the bus capacitor 1024 can be disposed simultaneously on the side close to the upper housing 100, and the heat dissipation structure 1024 of the upper housing 100 can also be used for heat dissipation of the components; at the same time, no clearance treatment is required on the lower housing 200, making the structure of the lower housing 200 more compact.

[0048] 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.
