Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive suspension technology, specifically to an integrated controller for a fully active automotive suspension. Background Technology
[0002] The suspension system is a collective term for all force-transmitting connections between a car's frame and axles or wheels. Its function is to transmit forces and torques acting between the wheels and the frame, and to buffer shocks and vibrations transmitted from uneven road surfaces to the frame or body, ensuring a smooth ride. As market demands for ride comfort and handling increase, active suspension, as a superior technological solution, is gradually becoming the mainstream. The fully active suspension integrated controller is a crucial calculation and control unit for active suspension, capable of adjusting suspension stiffness and damping in real time based on the vehicle's motion and road conditions. This real-time adjustment capability is faster and more precise than traditional controllers, helping the vehicle maintain optimal driving stability and ride comfort under different road conditions.
[0003] For example, Chinese patent application CN118400956A discloses an automotive suspension controller. This controller includes a controller body with densely packed heat dissipation vents at the top of its housing. A mounting frame covering the vents is fixed to the top of the housing. A pad is placed inside the mounting frame, with a ventilation opening in the middle of the pad. A groove is formed at the top of the pad, and a dustproof mesh for preventing dust accumulation is placed inside the groove. The dustproof mesh is detachably fixed to the pad. This invention, by adding a mounting frame and dustproof mesh above the heat dissipation vents, can prevent airborne dust from entering the controller body, thereby extending the controller body's service life. Furthermore, the dustproof mesh is detachable, facilitating its removal, replacement, or cleaning.
[0004] However, the aforementioned automotive suspension controller also has certain drawbacks: 1. The aforementioned suspension controller is relatively large in size, occupying a significant amount of interior space in the vehicle; 2. The aforementioned suspension controller has numerous connection interfaces, resulting in low integration and increasing the weight of the controller while also increasing the difficulty of assembly and maintenance; 3. The suspension controller uses a dustproof mesh plate for dust prevention, which can only reduce the probability of dust entering the controller's interior, but cannot completely prevent dust from entering. Utility Model Content

[0012] Furthermore, the base plate is made of aluminum alloy to improve the heat dissipation performance of the controller.
[0013] Its beneficial effects are: the aluminum alloy base plate ensures the heat dissipation performance of the controller, preventing the controller from degrading or malfunctioning due to overheating.
[0014] Furthermore, the base plate is provided with a groove, a waterproof and breathable membrane is provided in the groove, and a vent hole is provided in the middle of the groove.
[0015] Its beneficial effects are as follows: the setting of vents can balance the internal and external air pressure of the controller and improve the heat dissipation performance of the controller, while the setting of waterproof membrane improves the waterproof performance of the controller while allowing air to pass through.
[0016] Furthermore, the base plate and the outer casing are fixedly connected by screws.
[0017] Furthermore, sealant is provided at the joints between the controller housing, connector one, connector two, and controller base plate to prevent dust from entering the controller.
[0018] Its beneficial effects are: the use of sealant improves the controller's sealing performance, preventing dust from entering the controller and thus extending the controller's service life.
[0019] The beneficial effects of the fully active automotive suspension integrated controller provided by this utility model are:
[0020] 1. The integrated PCB board improves the integration of the controller, reduces its size, and saves interior space in the vehicle, while also reducing the weight of the controller; the design of connector one and connector two greatly reduces the number of interfaces, making the assembly and maintenance of the controller easier.
