One is the use of traditional cables, but cable connections suffer from drawbacks such as high contact resistance, susceptibility to loosening, and large space requirements.

The other category uses structures like BUSBARs, but existing BUSBARs often rely on bolt fixing or welding, lacking proper sealing and shielding designs for high-voltage environments. They are susceptible to electromagnetic interference (EMI), and insufficient contact area with terminals can lead to abnormal temperature rises. Furthermore, traditional BUSBARs have low integration, resulting in a large overall footprint. Utility Model Content

Detailed Implementation

[0032] The present invention provides a detailed description of an active suspension electro-hydraulic pump assembly with an electrical connection structure, in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims.

[0033] First Embodiment

[0034] Active suspension specifically comprises sensors, controllers, and actuators. Sensors detect the vehicle's state, such as vehicle acceleration, suspension displacement, and wheel speed. The controller processes this data and uses algorithms to calculate the required force or adjustment parameters. Finally, actuators (such as hydraulic or electromagnetic actuators) actually adjust the suspension. The key advantage of active suspension lies in its real-time adjustment, reacting to road surface changes within milliseconds to maintain vehicle stability. For example, when a wheel encounters a bump, the suspension can quickly contract to reduce the impact transmitted to the vehicle body; during cornering, active suspension can adjust stiffness to reduce body roll and improve handling.

[0035] In terms of actuators, active suspension typically uses hydraulic or electromagnetic systems. Hydraulic actuators offer fast response and high force, but are complex in structure and consume a lot of energy. Electromagnetic actuators, such as linear motors, may be more efficient, but their force output may not be as high as that of hydraulic systems.

[0036] The hydraulic actuator specifically includes a damper with a double-acting hydraulic cylinder and piston, a hydraulic pump head, a motor for driving the corresponding hydraulic pump, and a hydraulic unit with a hydraulic oil tank and valves. In other words, the electro-hydraulic pump unit includes a hydraulic pump and a motor for driving it. The working principle is that the electric motor drives the hydraulic pump to rotate forward or backward, driving hydraulic oil into the double-acting hydraulic cylinder, which then outputs damping to control the corresponding wheel suspension system.

[0037] An electrical connection structure is required between the motor, power supply, and controller of the active suspension electronic oil pump to transmit electrical energy, control signals, and detection signals. Traditional electrical connection methods often use cable connections or conventional BUSBAR structures, both of which have shortcomings. Therefore, please refer to... Figures 1-2This embodiment provides an active suspension electro-hydraulic pump assembly with an electrical connection structure, used to achieve safe and stable power transmission under an 800V high-voltage architecture, and to realize modular integration.

[0038] Specifically, this embodiment provides an active suspension electro-hydraulic pump assembly with an electrical connection structure, which includes a power supply unit, a motor housing 3, and an electrical connection unit 1. The power supply unit is connected to an external power source and is provided with a three-phase terminal 202 on the power supply side for transmitting electrical energy from the external power source to the motor, driving the motor to generate mechanical energy output.

[0039] The motor housing 3 is fixed to the surface of the motor and is provided with a plug-in slot 301.

[0040] The electrical connection part 1 is fixedly provided with a power receiving side three-phase terminal 101 and a plug-in part 103. The electrical connection part 1 is made by injection molding, so that the power receiving side three-phase terminal 101 and the electrical connection part 1 are integrated and fixed. That is, the power receiving side three-phase terminal 101 is made of metal material, and other areas of the electrical connection part 1 are mostly made of thermoplastic plastic, forming an integrated insulating package. There are no welding points or bolt connection points between the power receiving side three-phase terminal 101 and the body of the electrical connection part 1, which greatly improves the connection firmness and stability between the power receiving side three-phase terminal 101 and the electrical connection part 1.

[0041] The three-phase terminal 101 on the power receiving side is electrically connected to the three-phase terminal 202 on the power supply side and the three-phase port of the motor, so that the electrical energy output from the external power supply can be transmitted to the motor in sequence through the power supply part and the electrical connection part 1.

[0042] The plug-in part 103 and the plug-in slot 301 are plugged and plugged in. When the plug-in part 103 is fully inserted into the plug-in slot 301, the power supply part, the electrical connection part 1 and the motor can maintain a relatively fixed position, that is, the fixed connection function of the power supply part, the electrical connection part 1 and the motor is realized.

[0043] The structure and function of an active suspension electro-hydraulic pump assembly with an electrical connection structure provided in this embodiment will be described in further detail below:

[0044] Preferably, in one embodiment, the power supply unit further includes a power supply side PCBA circuit board 201, the power supply side three-phase terminals 202 are electrically connected to the power supply side PCBA circuit board 201, and the power supply side PCBA circuit board 201 is used to adjust the electrical energy parameters supplied to the motor.

[0045] Each power supply side three-phase terminal 202 is provided with a clamping part 203. In one embodiment, the clamping part 203 is a claw structure with an opening in the middle. When the pin of the power receiving side three-phase terminal 101 is inserted into the opening in the middle of the clamping part 203 of the power supply side three-phase terminal 202, the claw structures on both sides of the clamping part 203 will apply clamping force to both sides of the power receiving side three-phase terminal 101, thereby achieving the function of fixed connection between the power supply side three-phase terminal 202 and the power receiving side three-phase terminal 101. Through the above connection method, the portability and stability of the connection between the power supply side three-phase terminal 202 and the power receiving side three-phase terminal 101 can be effectively improved.

[0046] In one embodiment, the clamping structure forming the clamping part 203 has springs on both sides. When there is an eccentricity between the pin of the power receiving side three-phase terminal 101 and the clamping part 203 of the power supply side three-phase terminal 202 during the docking and installation process, the elastic force of the spring can make up for the installation tolerance, thereby maintaining good contact between the power receiving side three-phase terminal 101 and the power supply side three-phase terminal 202.

[0047] Furthermore, a gap is provided between adjacent power-receiving three-phase terminals 101, and the positions of the power supply three-phase terminals 202 and the power receiving three-phase terminals 101 correspond one-to-one. When the power receiving three-phase terminal 101 is fully inserted into the power supply three-phase terminal 202, accidental contact between the power supply three-phase terminal 202 and the adjacent power receiving three-phase terminal 101 can be avoided. In addition, the pins of the power receiving three-phase terminal 101 are provided with a chamfer 102 to ensure smooth assembly of the power supply three-phase terminal 202 and the power receiving three-phase terminal 101.

[0048] Preferably, in one embodiment, the electrical connection structure further includes a stator three-phase wire 104. The first end of the stator three-phase wire 104 is electrically connected to the three-phase port of the motor, and the second end of the stator three-phase wire 104 is electrically connected to the power receiving side three-phase terminal 101. Specifically, the conductive core wires of the stator three-phase wire 104 can be electrically connected to the three-phase port of the motor and the conductive area of ​​the power receiving side three-phase terminal 101 by soldering or resistance welding.

[0049] Among them, the three-phase terminal 101 on the power receiving side facing the stator three-phase wire 104 is provided with a U-shaped structure to accommodate the stator three-phase wire 104. The U-shaped structure is used to ensure the contact area between the three-phase terminal 101 on the power receiving side and the stator three-phase wire 104.

[0050] Preferably, in one embodiment, the insertion slot 301 is a semi-open slot-shaped structure, which can be selected as a semi-circular or rectangular structure. The shape of the insertion part 103 is adapted to the insertion slot 301. When the insertion part 103 and the insertion slot 301 are inserted, the insertion part 103 and the insertion slot 301 are fixedly connected by interference fit or adhesive bonding, thereby achieving the effect of fixing the relative positions of the power supply part, the electrical connection part 1 and the motor.

[0051] Preferably, in one embodiment, screw bushings 105 are provided on both sides of the electrical connection part 1, and screw holes 302 are provided at opposite positions of the motor housing 3. When the plug part 103 is fully inserted into the plug groove 301, the screw bushings 105 and the screw holes 302 are vertically opposite each other. Screws 303 are passed through the screw bushings 105 and the screw holes 302 to fix the electrical connection part 1 and the motor housing 3, thereby further improving the connection stability between the electrical connection part 1 and the motor housing 3.

[0052] Preferably, in one embodiment, the screw bushing 105 is made of cold-rolled steel plate to improve the mechanical properties of the screw bushing 105, and the surface of the screw bushing 105 is coated with a zinc-nickel plating layer to ensure the salt spray reliability of the screw bushing 105.

[0053] Preferably, in one embodiment, the surface of the power receiving three-phase terminal 101 is coated with a silver plating layer to reduce the contact resistance between the power supply three-phase terminal 202 and the power receiving three-phase terminal 101, thereby preventing abnormal temperature rise.

[0054] Preferably, in one embodiment, the electrical connection part 1 further includes a receiving cavity 106, in which a magnetic angle sensor PCBA circuit board 107 is placed. The magnetic angle sensor PCBA circuit board 107 is used to measure the rotation angle data of the motor rotor. Specifically, a magnetic angle sensor is a device that uses a magnetic field to detect the angular position of a rotating object. In this embodiment, it can determine the position of the rotor by sensing changes in the magnetic field, thereby providing accurate measurement results such as the rotation angle and rotation speed of the motor.

[0055] Preferably, in one embodiment, the size of the magnetically encoded angle sensor PCBA circuit board 107 is adapted to the size of the accommodating cavity 106, and the inner wall of the accommodating cavity 106 is provided with a plurality of buckles 108 for limiting the magnetically encoded angle sensor PCBA circuit board 107 to prevent the magnetically encoded angle sensor PCBA circuit board 107 from moving in the accommodating cavity 106.

[0056] The accommodating cavity 106 includes an irregular, irregular structure.

[0057] Furthermore, the bottom edge of the accommodating cavity 106 is provided with a support platform 109 for supporting the magnetically encoded angle sensor PCBA circuit board 107. When the magnetically encoded angle sensor PCBA circuit board 107 is placed in the accommodating cavity 106, the bottom surface of the magnetically encoded angle sensor PCBA circuit board 107 is in direct contact with the top surface of the support platform 109. There is a gap between the bottom surface of the magnetically encoded angle sensor PCBA circuit board 107 and the bottom surface of the accommodating cavity 106 to prevent the components on the PCBA circuit board from being squeezed and to improve the heat dissipation effect of the magnetically encoded angle sensor PCBA circuit board 107.

[0058] Preferably, in one embodiment, the electrical connection part 1 is provided with a plurality of wire harness holes 110, and a ribbon cable 111 is provided to pass through the wire harness holes 110. The wire harness holes 110 are used to fix the ribbon cable 111. The first end of the ribbon cable 111 is electrically connected to the magnetically coded angle sensor PCBA circuit board 107, and the second end of the ribbon cable 111 is electrically connected to an external controller. The ribbon cable 111 is used to transmit the measurement data of the magnetically coded angle sensor PCBA circuit board 107 to the external controller, and to transmit the control signal of the external controller to the magnetically coded angle sensor PCBA circuit board 107. Specifically, the ribbon cable 111 and the magnetically coded angle sensor PCBA circuit board 107 can be connected by welding or clipping 108, and the connection point between the ribbon cable 111 and the magnetically coded angle sensor PCBA circuit board 107 can be further reinforced with tape to ensure a firm connection.
