[0001] This utility model relates to the field of electronic circuit technology, and in particular to a structural layout of a high-voltage shock absorber. Background Technology

[0002] Traditional high-voltage suspension shock absorbers have their DC input connector fixed to the top cover, while the drive board is mounted on the motor housing and connected via a connector harness. This separate structure makes it difficult to secure the harness, and additional length is required for installation. When installed on a vehicle, the harness can vibrate with the vehicle, posing a risk of damage to the electrical components on the board. Utility Model Content

[0003] This utility model provides a structural layout for a high-pressure shock absorber, aiming to solve at least one defect in the prior art.

[0004] This utility model embodiment provides a structural layout for a high-voltage shock absorber, including: a cover, a power input connector, a drive board, a control board, and an adapter board;

[0005] The power input connector is disposed outside the cover, the control board and the adapter board are disposed inside the cover, and the power input connector is connected to the adapter board inside the cover;

[0006] The drive board is equipped with a bus power connector. When the drive board is combined with the cover, the bus power connector is connected to the adapter board.

[0007] The power input connector is used to connect to a power source, the adapter board is used for the electrical connection between the power input connector and the drive board, the power source is used as the bus power source for the drive board, and the control board is used to generate control signals for the drive board.

[0008] Optionally, the adapter board is configured with a first pad, and the power input connector is configured with a wire harness with terminals;

[0019] Optionally, the high-pressure shock absorber is a high-pressure shock absorber for vehicle suspension.

[0020] Compared with existing technologies, the advantages of this invention are as follows: This invention proposes a structural layout for a high-voltage shock absorber, which includes a power input connector, a cover, an adapter plate, and a drive plate. The power input connector is directly connected to the adapter plate inside the cover, and the drive plate is connected to the adapter plate via a bus power connector. This compact layout design greatly reduces the connection distance between components. Compared with the traditional distributed layout, long-distance wiring is eliminated, thus effectively shortening the length of the high-voltage connector harness.

[0021] In applications such as vehicles, vibration is frequent. Excessively long wiring harnesses are prone to shaking and pulling during vibration, potentially leading to loose connectors, worn cable sheaths, or even broken internal wires, thus affecting the normal operation of the high-voltage vibration isolator. The high-voltage vibration isolator in this solution shortens the wiring harness length through optimized layout, allowing for stable arrangement within a limited space. This reduces the harness's movement space, lowers the risk of impact and damage from vibration to the wiring harness and connecting devices, improves the reliability and stability of the high-voltage vibration isolator in vibration environments, and extends its overall service life.

[0022] In this solution, the control board and adapter board are integrated into the cover, the power input connector is external and directly connected to the adapter board, and the drive board is connected to the adapter board through a specific connector. This layout makes the functional areas of each component clear and the connection path simple and efficient. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] Figure 1 This is a structural block diagram of the high-voltage shock absorber in the embodiment, with reference to... Figure 1 The high-voltage shock absorber includes: a cover 1, a power input connector 2, a drive board 5, a control board 4, and an adapter board 3.

[0028] The power input connector 2 is located outside the cover 1, while the control board 4 and the adapter board 3 are located inside the cover 1. The power input connector 2 is connected to the adapter board 3 inside the cover 1.

[0029] The drive board 5 is equipped with a bus power connector. When the drive board 5 is combined with the cover 1, the bus power connector is connected to the adapter board 3.

[0030] The power input connector 2 is used to connect to the power supply, the adapter board 3 is used for the electrical connection between the power input connector 2 and the drive board 5, the power supply is used as the bus power supply for the drive board 5, and the control board 4 is used to generate control signals for the drive board 5.

[0031] For example, in this solution, the cover 1 is designed to install and fix the control board 4 and the adapter board 3, providing them with physical protection to prevent external dust, moisture, mechanical collisions, etc., from damaging the internal circuitry. The cover 1 can be the upper cover or the lower cover of the high-voltage shock absorber. The upper cover and the lower cover can be combined, and the drive board 5 can be set in the space formed by the upper cover and the lower cover.

[0032] For example, in this solution, the power input connector 2 is used to connect the high-voltage shock absorber to an external (DC) power supply, which provides power to the entire high-voltage shock absorber. The interface type of the power input connector 2 can be selected according to actual needs, for example, it can be an aviation plug, terminal block, etc.

[0033] The power input connector 2 is fixedly connected to the cover 1. The secure connection between the two can prevent the power input connector 2 from becoming loose or damaged due to vibration, plugging or unplugging.

[0034] For example, in this solution, the adapter board 3 acts as a bridge between the power input connector 2 and the drive board 5, and is responsible for the electrical connection between the two. It stably and reliably transmits the electrical energy introduced by the power input connector 2 to the drive board 5, and provides bus power to the drive board 5.

[0035] For example, in this solution, the connection method between the power input connector 2 and the adapter board 3 can be as follows:

[0036] The pins of the power input connector 2 are connected to the cable (such as a multi-core power cable) by soldering or crimping; the other end of the cable is connected to the socket interface on the adapter board 3 via a connector (such as a terminal connector or ribbon cable plug).

[0037] Solder the socket interface on the PCB of adapter board 3, and connect the pins of the socket interface to the power supply traces inside the board.

[0038] Alternatively, the power input connector 2 can be a pinned board-mounted model (such as a through-hole DC female connector, pin-type power connector, etc.), with the pins directly inserted into the PCB pads of the adapter board 3.

[0039] The power input connector 2 is fixed to the cover 1 and the adapter plate 3 by mechanical fasteners.

[0040] The PCB of the adapter board 3 has vias that match the pins of the power input connector 2. After the pins of the power input connector 2 are inserted, they are fixed by soldering, and the pads are connected to the power bus.

[0041] Alternatively, the cable of the power input connector 2 can be connected to the terminal block or pad on the PCB of the adapter board 3 via cold-pressed terminals (such as OT terminals or U-type terminals), and the adapter board 3 can be connected to the corresponding terminals of the terminal block via PCB traces or wires.

[0042] For example, in this solution, the driver board 5 is provided with a connection method between the driver board 5 and the adapter board 3, which can be:

[0043] Male connectors can be installed on driver board 5, and the pins of the male connectors are connected to the pads of the bus power connector; female connectors are installed at the corresponding positions on adapter board 3, and the pins of the female connectors are connected to the input path of power input connector 2 through PCB traces.

[0044] The driver board 5 and the adapter board 3 are connected via male connectors.

[0045] Alternatively, the driver board 5 can be designed with gold fingers (gold-plated copper foil contacts) on its edge, with the length of the gold fingers designed according to the current requirements; the adapter board 3 can be fitted with a slot connector (such as a PCIe slot), and the metal spring inside the slot connector can make close contact with the gold fingers, thereby enabling the driver board 5 to be connected to the adapter board 3.

[0046] Alternatively, a metal elastic contact piece is fixed on the adapter board 3, with one end of the metal elastic contact piece soldered to the power trace of the corresponding power input connector 2 on the PCB, and the other end forming a contact point facing upwards; a metal contact piece is installed at the corresponding position on the driver board 5.

[0047] When the drive plate 5 is combined with the cover 1, the mechanical pressure between the two causes the metal elastic contact piece to adhere to the metal contact piece, thereby connecting the drive plate 5 with the adapter plate 3.

[0048] For example, in this solution, the main function of the control board 4 is to generate the control signals required by the drive board 5. By precisely regulating these signals, the working state of the drive board 5 can be controlled, thereby controlling the operation of the entire system.

[0049] The control board 4 can integrate high-performance microprocessors, signal processing chips and other devices to realize complex control algorithms and logic processing; the control board 4 can also include interface circuits, such as interfaces with external sensors and communication modules, to obtain system operating status information and realize data interaction.

[0050] For example, in this solution, after the driver board 5 receives the bus power transmitted by the adapter board 3, it converts the electrical energy into the energy form required to drive the external load, and drives the external device to operate according to the control signal generated by the control board 4.

[0051] The driver board 5 may include a power amplifier circuit, a switching circuit (MOS transistor drive circuit), a protection circuit (overcurrent protection circuit, overvoltage protection circuit, etc.), an inverter circuit, etc.

[0052] For example, in this solution, the driver board 5 and the control board 4 can be physically connected through connectors (such as pin connectors or board-to-board connectors).

[0053] This embodiment proposes a high-voltage shock absorber, which includes a power input connector, a cover, an adapter plate, and a drive plate. The power input connector is directly connected to the adapter plate inside the cover, and the drive plate is connected to the adapter plate via a bus power connector. This compact layout design greatly reduces the connection distance between components. Compared to the traditional distributed layout, long-distance wiring is eliminated, thus effectively shortening the length of the high-voltage connector harness.

[0054] In applications such as vehicles, vibration is frequent. Excessively long wiring harnesses are prone to shaking and pulling during vibration, potentially leading to loose connectors, worn cable sheaths, or even broken internal wires, thus affecting the normal operation of the high-voltage vibration isolator. The high-voltage vibration isolator in this solution shortens the wiring harness length through optimized layout, allowing for stable arrangement within a limited space. This reduces the harness's movement space, lowers the risk of impact and damage from vibration to the wiring harness and connecting devices, improves the reliability and stability of the high-voltage vibration isolator in vibration environments, and extends its overall service life.

[0055] In this solution, the control board and adapter board are integrated into the cover, the power input connector is external and directly connected to the adapter board, and the drive board is connected to the adapter board through a specific connector. This layout makes the functional areas of each component clear and the connection path simple and efficient.

[0056] Based on any of the aforementioned solutions, in one possible implementation, the adapter board is provided with a first pad, and the power input connector is provided with a wire harness with terminals; the wire harness is fixedly connected to the first pad through the terminals.

[0057] In this solution, the power input connector is selected with an adapter wire harness. One end of the wire harness is securely connected to the power input connector, and the other end is crimped with a metal terminal. The metal terminal can be made of copper or copper alloy.

[0058] In this solution, the adapter board is designed with a first pad. The shape of the first pad can be circular, square, etc., and the size is determined according to the current. Generally, the pad area needs to be increased in high current scenarios.

[0059] In this solution, the terminal wire harness configured on the power input connector is fixedly connected to the first pad on the adapter board to construct a power transmission path, thereby achieving the purpose of stable power transmission.

[0060] In this solution, compared to using complex connectors, the connection method between wire harness terminals and solder pads reduces the procurement cost of dedicated connectors. The fixed connection achieved through soldering can form a stable electrical connection point with low contact resistance, which can reduce power loss and heat generation during power transmission.

[0061] Based on any of the aforementioned solutions, in one possible implementation, the terminals are OT terminals.

[0062] In this solution, the OT terminal is a circular cold-pressed terminal block with one end being a ring structure (compatible with bolts or solder posts), and the other end being crimped to the wire harness. The OT terminal is crimped to the end of the wire harness of the power input connector, and the OT terminal is connected to the first pad of the adapter board by soldering or bolting.

[0063] For example, in this solution, the corresponding OT terminal is selected according to the wire harness diameter and current requirements. A first pad matching the OT terminal is provided on the adapter board, and the size of the pad must meet the coverage area of ​​the annular opening of the OT terminal.

[0064] Place the OT terminal ring end onto the first pad of the adapter board and tighten it with a nut to achieve mechanical and electrical connection (suitable for high current scenarios, quick installation without soldering).

[0065] Based on any of the aforementioned solutions, in one possible implementation, the adapter board is equipped with mating copper plates; the bus power connector is connected to the adapter board via the mating copper plates.

[0066] In this solution, a stable electrical connection between the bus power connector and the adapter board is achieved using mating copper contacts. When the drive board and the cover are combined and connected, the bus power connector and the mating copper contacts on the adapter board precisely align, forming a power transmission channel through physical contact to provide the required bus power to the drive board. The entire process requires no soldering, facilitating disassembly and maintenance.

[0067] For example, in this solution, the thickness and size of the copper sheet are determined based on the current magnitude and mechanical strength requirements. The copper sheet is then stamped into a specific shape to give it good elasticity and suitable insertion and extraction force.

[0068] For example, in this solution, the mating copper piece may include a contact portion, which is the part that directly contacts the mating copper piece and the bus power connector; an elastic portion, which adopts a bending, corrugated, or cantilever beam structure design to give the copper piece a certain degree of elasticity. During the mating and disassembly process with the bus power connector, the elastic portion can generate appropriate elastic force to ensure that the contact portion fits tightly with the connector, while providing a certain buffer during insertion and removal operations to prevent hard collisions from damaging components; and a fixing portion, which is used to securely mount the mating copper piece on the adapter board.

[0069] For example, in this solution, mounting holes and connection pads are pre-drilled on the PCB of the adapter board according to the size and position of the interposer copper contacts. The interposer copper contacts are fixed to the adapter board by soldering or riveting to ensure reliable electrical connection between the copper contacts and the adapter board.

[0070] For example, during the assembly and connection of the driver board and the cover, the elasticity and guiding structure of the mating copper plates allow the bus power connector to automatically align and insert. As the driver board is installed in place, the bus power connector and the mating copper plates make full contact, forming a stable electrical connection and completing the power supply connection for the driver board.

[0071] For example, in this solution, the bus power connector is used to stably transmit electrical energy from the adapter board to the drive board. The bus power connector can use flat copper busbars or elastic copper sheets as conductive contacts to make conductive connections with the mating copper sheets.

[0072] Based on any of the aforementioned solutions, in one possible implementation, the adapter board and the control board are mounted on a single PCB, with the adapter board located in the high-voltage area and the control board located in the low-voltage area; an isolation section is provided between the high-voltage area and the low-voltage area.

[0073] In this solution, the adapter board and control board can be mounted on a single PCB, which is divided into high-voltage and low-voltage areas based on voltage levels and functional characteristics. The high-voltage area, where the adapter board is located, is responsible for transmitting high voltage and high current, providing bus power to the driver board; the low-voltage area, where the control board is located, focuses on signal processing and logic control, generating the control signals required by the driver board.

[0074] In this design, an isolation section is installed between the high-voltage and low-voltage areas to reduce electromagnetic interference between the high-voltage and low-voltage circuits and ensure that each functional module operates independently and stably.

[0075] In this solution, the isolation section can be created by methods such as slotting or filling with insulating material. For example, slots of appropriate depth and width can be milled into the PCB to cut off the electrical path between high and low voltage areas; or insulating materials such as epoxy resin can be filled between the high and low voltage areas.

[0076] For example, in this solution, electromagnetic interference can also be shielded by laying a grounded metal shielding layer (such as copper foil) in the isolation section; a grounded metal isolation wall can also be set between high and low voltage areas to further enhance the shielding effect.

[0077] For example, in this solution, the spacing between high and low voltage areas can be increased and clear boundary markers can be set during PCB layout; physical barriers such as plastic partitions can also be installed between high and low voltage areas.

[0078] In this solution, by setting up an isolation section, electromagnetic interference from the high-voltage area to the low-voltage area can be effectively prevented, thereby improving the quality of the control signal and reducing the probability of system failure.

[0079] Based on any of the aforementioned solutions, in one possible implementation, the isolation section includes a shielding plate.

[0080] In this solution, a shielding plate is set up as an isolation component between the high-voltage area and the low-voltage area, which can achieve a dual physical and electromagnetic protection barrier.

[0081] In this scheme, appropriate metal materials (such as copper, aluminum or tin-plated steel plates) and the size of the shielding plate can be selected according to the working environment and electromagnetic interference intensity of the high-voltage shock absorber.

[0082] Based on any of the aforementioned solutions, in one possible implementation, a filter component is provided on the adapter board for filtering the power supply.

[0083] In this solution, the power supply is a DC power supply. The filtering components are mainly used to reduce ripple, high-frequency noise and common-mode interference in the DC power supply, and output stable and clean DC power to ensure that the downstream load is not affected by power fluctuations.

[0084] In this solution, the filtering components may include capacitors and inductors, which can form an LC filter circuit or a common-mode filter circuit.

[0085] Based on any of the aforementioned solutions, in one possible implementation, the filtering component includes a filtering capacitor.

[0086] In this solution, the filtering component can be specifically designed as a power filtering circuit. The filtering capacitors include X capacitor and Y capacitor. The common mode inductor, X capacitor and Y capacitor are soldered on the adapter board. The positive and negative terminals of the power input connector pass through the two windings of the common mode inductor respectively. The common mode inductor is connected in parallel with X capacitor and Y capacitor to ground.

[0087] Based on any of the aforementioned schemes, in one possible implementation scheme, the power supply is 400-1000V DC.

[0088] In this scheme, the high-voltage shock absorber is set to be used in high-voltage scenarios, and preferably, the power supply is 800V DC.

[0089] Based on any of the aforementioned schemes, in one possible implementation scheme, the high-pressure shock absorber is a high-pressure shock absorber for vehicle suspension.

[0090] In this solution, the high-pressure shock absorber for vehicle suspension is used to adjust the dynamic performance of the vehicle suspension system. It is mainly used for intelligent suspension systems such as active suspension and semi-active suspension. By controlling the actuator (such as a motor), it can achieve adaptive adjustment of suspension damping, stiffness or vehicle height.

[0091] For example, in this solution, the high-voltage shock absorber of the vehicle suspension can be installed on the housing of the motor, and the power input connector adopts a high-voltage connector, which is connected to the bus of the power battery.

[0092] Figure 2 This is a schematic diagram of the high-pressure shock absorber in the embodiment. Figure 3 This is a schematic diagram showing the layout of the adapter board and control board in the embodiment. (Refer to...) Figure 2 and Figure 3 Based on any of the aforementioned schemes, in one possible implementation scheme, the high-voltage shock absorber includes:

[0093] The system comprises: cover 1, power input connector 2, adapter board 3, control board 4, and drive board 5. Adapter board 3 contains filter capacitors 6 (including X and Y capacitors), and copper mating plates 7 are soldered onto it. Busbar power connector 8 is soldered onto drive board 5.

[0094] For example, in this solution, cover 1 is the upper cover plate of the high-pressure shock absorber, and the high-pressure shock absorber can also be configured with a lower cover plate that works in conjunction with the upper cover plate.

[0095] The adapter board 3 and the control board 4 are located inside the cover 1. The power input connector 2 is installed on the cover 1. The power input connector 2 and the adapter board 3 are located in the high voltage zone 100, and the control board 4 is located in the low voltage zone 200. A wall is erected between the high voltage zone and the low voltage zone (referring to the formation of a structure for isolating high and low voltage zones, preventing signal interference, short circuits, or achieving physical separation. This structure can be a metal isolation strip, a physical milling groove, etc.) and is separated by a shielding plate.

[0096] In this solution, the power input connector 2 is equipped with a wire harness with OT terminals. The OT terminals are fastened to the pads of the adapter plate 3 by bolts, thereby leading the current from the external power source (such as a power battery) of the high voltage shock absorber to the mating copper plates 7 soldered on the adapter plate 3 through the wire harness and the pads.

[0097] In this solution, the wiring harness of the power input connector 2 is connected to the adapter board 3, and then the mating copper pieces 7 are soldered onto the adapter board 3. When the drive board 5 is placed on the cover 1, the bus power connector 8 is mated with the mating copper pieces 7, thereby realizing the power supply to the drive board 5.

[0098] In this solution, the power input connector 2 and the drive board 5 are electrically connected by an adapter plate set inside the cover 1, which can shorten the wire harness length of the power input connector 2 and avoid damage to the device during vibration due to excessive wire harness length.

[0099] In this solution, in order to optimize the shielding effect between the high-voltage and low-voltage areas, the power input connector 2 and the filter capacitor 6 are placed on the adapter board 3, thereby separating them from the control board in the low-voltage area and reducing signal interference between high and low voltage areas.
