Description

Technical Field

[0001] This invention relates to a shock absorber and its control method, specifically to an anti-deviation shock absorber and its manufacturing method. Background Technology

[0002] Vehicles experience vibrations while driving, which are absorbed by shock absorbers. To quickly dampen vibrations between the chassis and body, improving ride smoothness and comfort, shock absorbers are typically installed in the vehicle's suspension system. Double-acting telescopic shock absorbers are widely used in automobiles. Shock absorbers are wear-prone components during vehicle use, and their performance directly affects the vehicle's stability. Therefore, it's crucial to consider shock absorber operation promptly. Timely collection of driving data can make shock absorber operation more intelligent, ensuring they are always in good working order.

[0003] In the prior art: CN202022057011.7, an improved automobile shock absorber is disclosed. This utility model discloses an improved automobile shock absorber, belonging to the technical field of automobile shock absorber. It includes a crossbeam frame, with fixed plates fixedly connected to both ends of the crossbeam frame. Movable plates are movably connected to the inner sidewalls of the two fixed plates. A first spring is connected between the top of the movable plate and the bottom of the crossbeam frame. A fixed rod is connected between the inner sidewalls of the two movable plates. A fixed cylinder is fixedly connected to the outer side of the middle of the fixed rod. A buffer assembly is connected between the top of the fixed cylinder and the bottom of the crossbeam frame. A buffer plate is provided below the fixed rod. Shock-absorbing assemblies are installed on both sides of the fixed cylinder between the crossbeam frame and the fixed cylinder.

[0004] Although existing shock absorbers are scientifically designed, safe and convenient to use, and can buffer and dampen bumps in the car multiple times during use with good damping effect, there is a problem of low level of intelligence when it comes to further intelligent control of shock absorbers. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides an anti-deviation shock absorber and its processing method.

[0006] The present invention is achieved by the following technical solution: A shock absorber for preventing deviation, comprising a shock absorber, an active space within the shock absorber, a piston rod within the active space, an assembly component on the piston rod, the assembly component being an assembly hole, a front support plate and a rear support plate on the piston rod, a protective component between the front support plate and the rear support plate, a slot on the front support plate and the rear support plate, the protective component passing through the slot, the protective component being a protective rod, characterized in that: an electric field sensing component is provided on the outside of the protective rod;

[0007] The electric field sensing component is an induction coil, which is an electromagnetic induction coil. The electromagnetic induction coil is an external electromagnetic induction coil, which is distributed outside the shock absorber. An energizing component is provided outside the electromagnetic induction coil, and the energizing component and the electromagnetic induction coil are connected to each other.

[0008] The external electromagnetic induction coil is a partitioned external electromagnetic induction coil, which is divided into A-zone external electromagnetic induction coil, B-zone external electromagnetic induction coil and C-zone external electromagnetic induction coil. A coil isolation component is provided between the A-zone external electromagnetic induction coil, B-zone external electromagnetic induction coil and C-zone external electromagnetic induction coil.

[0009] The coil isolation component is a soft magnetic isolation component, which is a soft magnetic plate. The soft magnetic plate is made of silicon steel sheet, and the silicon steel sheet is coated with a soft magnetic coating. The soft magnetic coating is made of Fe-BM soft magnetic alloy, which is an amorphous nanocrystalline soft magnetic alloy with the chemical composition formula FexByPzCaCubMc. The soft magnetic isolation component is distributed in the interval area between the external electromagnetic induction coils in area A, area B, and area C.

[0010] The activity space is filled with hydraulic oil, which is filled with magnetic particles to form a magnetofluid. The magnetic particles are spherical. These spherical magnetic particles are magnetically actuated by an external electromagnetic induction coil. When the external electromagnetic induction coil is powered on, it generates a magnetic field. This magnetic field causes the spherical magnetic particles to aggregate, further increasing the concentration of the hydraulic oil and slowing down the piston rod's movement. This increases the piston rod's resistance. When the external electromagnetic induction coil is de-energized, the spherical magnetic particles disperse, thus reducing the piston rod's resistance.

[0011] The production process includes the following steps:

[0012] Step 1: Selection and preparation of metal parts. When selecting metal parts, it is necessary to choose metal parts with strong corrosion resistance. Then, these metal parts are used for cutting production on a lathe. Through the cutting production on the lathe, the shock absorber cylinder and piston rod can be manufactured. During the cutting production on the lathe, it is necessary to ensure the smoothness of the outer surface of the shock absorber cylinder and piston rod to ensure the machining accuracy.

[0013] After the shock absorber cylinder and piston rod are manufactured, a preliminary assembly process is required. During assembly, operators assemble the shock absorber and piston rod according to the drawings. The assembly can be carried out in the order of the components. After the preliminary assembly, an injection port for injecting magnetic fluid needs to be reserved.

[0014] The second step: After the shock absorber is initially assembled, the magnetic fluid can be prepared. The magnetic fluid contains micro-nano-level magnetic particles. The magnetic fluid is formed by the mixing of micro-nano-level magnetic particles and hydraulic oil. The magnetic fluid needs to be injected into the shock absorber. When injecting the magnetic fluid into the shock absorber, a vacuum filling machine is needed to fill the magnetic fluid.

[0015] When filling the magnetic fluid using a vacuum filling machine, the magnetic fluid material needs to be prepared. Micro-nano-level magnetic particles and hydraulic oil are premixed. During premixing, stirring equipment can be used for stirring. After stirring, the temperature of the magnetic fluid needs to be controlled at 20-30 degrees Celsius. The magnetic fluid formed after premixing and stirring is then filtered using a filter screen. After filtration, it is heated appropriately, and the heating temperature is maintained at 35-45 degrees Celsius.

[0016] At this point, the heated magnetic fluid is filled using a vacuum filling machine. During filling, the shock absorber needs to be evacuated. The shock absorber is evacuated using a vacuuming device, and then the magnetic fluid is filled. The magnetic fluid is filled into the shock absorber using the vacuum filling machine. A sealing component is then installed on the shock absorber to seal the magnetic fluid inside the shock absorber.

[0017] The third step is to install the external electromagnetic induction coils of the shock absorber. During installation, the external electromagnetic induction coils are installed in different locations on the shock absorber, which can be divided into areas A, B, and C. Operators bind the external electromagnetic induction coils to areas A, B, and C. The circuit connection of the external electromagnetic induction coils is then performed. Each external electromagnetic induction coil has pre-installed coil leads, which are spot-welded to the energized components. Further connections are then made using the energized components and wires. When fixing the external electromagnetic induction coils to the outside of the shock absorber, an expansion gap needs to be allowed. Finally, the external electromagnetic induction coils in areas A, B, and C undergo high-temperature treatment. During high-temperature treatment, epoxy resin is directly sprayed onto the external electromagnetic induction coils, forming a high-temperature protective layer.

[0018] Magnetofluids rely on magnetic particles to form a liquid with micron-sized magnetic particles suspended in it. Without the action of an external magnetic field, the viscosity of the magnetofluid is similar to that of ordinary liquids. When it flows, it can rely on the liquid with micron-sized magnetic particles to flow. When an external electromagnetic induction coil set outside the shock absorber is energized, the magnetic coil generates a magnetic field. The magnetic particles are arranged along the direction of the magnetic field to form a chain or network structure, which further increases the viscosity of the magnetofluid. The increased viscosity of the magnetofluid leads to an increase in damping force, making it suitable for high-damping conditions.

[0019] During adjustment, the strength of the magnetic field is controlled by the magnitude of the current. At the same time, the magnetic field can be controlled by three external electromagnetic induction coils at different positions, which can meet the needs of different magnetic field releases. The external electromagnetic induction coil in area A can release the magnetic field in area A, the external electromagnetic induction coil in area B can release the magnetic field in area B, and the external electromagnetic induction coil in area C can release the magnetic field in area C.

[0020] Permanent magnet auxiliary devices are installed inside the external electromagnetic induction coils of Zone A and Zone B. The permanent magnet auxiliary devices are permanent magnets. The permanent magnets, together with the external electromagnetic induction coils of Zone A and Zone B, form a basic auxiliary magnetic field. The basic auxiliary magnetic field can extend the life of the external electromagnetic induction coils of Zone A and Zone B, enabling the shock absorber electromagnetic coils to operate with low energy consumption.

[0021] A soft magnetic isolation component is installed between the external electromagnetic induction coils in areas A, B, and C. This soft magnetic isolation component is a soft magnetic plate made of silicon steel sheet, coated with a soft magnetic coating made of Fe-BM-based soft magnetic alloy. The Fe-BM-based soft magnetic alloy is an amorphous nanocrystalline soft magnetic alloy with the chemical formula FexByPzCaCubMc. This soft magnetic isolation component further partitions the electromagnetic field in different areas, allowing for the control of different levels of magnetohydrodynamic flux, thus meeting the needs of intelligent shock absorbers.

[0022] A current feedback device is installed between the energized component and the external electromagnetic induction coil. The current feedback device can monitor the magnitude of the current in real time. The current feedback device uses a Hall sensor. When the current enters the battery induction coil through the coil lead, the Hall sensor feeds back the monitored current value to the pulse width modulation controller. The pulse width modulation controller adjusts the output current based on the feedback current value to achieve precise control of the magnetic field strength.

[0023] Compared to existing technologies, this invention, when adjusting the internal resistance of the shock absorber, can control the viscosity of the magnetic fluid using external electromagnetic induction coils. The interaction between the magnetic particles within the magnetic fluid and the electromagnetic induction coils allows the mixture of hydraulic oil and magnetic particles to modulate and adjust the resistance of the magnetic fluid. The strength of the magnetic field is controlled by the magnitude of the current. Furthermore, the magnetic field can be controlled using three external electromagnetic induction coils at different locations, satisfying the needs for releasing different magnetic fields. The external electromagnetic induction coil in area A can release a magnetic field in area A, the external electromagnetic induction coil in area B can release a magnetic field in area B, and the external electromagnetic induction coil in area C can release a magnetic field in area C.

[0024] To divide the external electromagnetic induction coil into regions that release the magnetic field, the external electromagnetic induction coil can be divided into different regions. The resistance to the flow of the magnetofluid can be controlled at different locations by using external electromagnetic induction coils in different regions. Permanent magnet auxiliary devices are installed inside the external electromagnetic induction coils in regions A and B. These permanent magnet auxiliary devices use permanent magnets. The permanent magnets, together with the external electromagnetic induction coils in regions A and B, form a basic auxiliary magnetic field. This basic auxiliary magnetic field can extend the lifespan of the external electromagnetic induction coils in regions A and B, enabling low-energy operation of the shock absorber's electromagnetic coil.

[0025] The soft magnetic isolation components installed between the external electromagnetic induction coils in Zone A, Zone B, and Zone C further divide the electromagnetic fields in different areas. By utilizing the electromagnetic fields in different areas, magnetofluids of varying strengths can be controlled, thus meeting the needs of intelligent shock absorbers. The soft magnetic isolation components enable the initial isolation and division of the magnetic fields between electromagnetic regions, preventing the magnetic fields in different regions from affecting each other.

When the external electromagnetic induction coil is powered on, it generates a magnetic field. This magnetic field causes the spherical magnetic particles to aggregate, further increasing the concentration of the hydraulic oil and slowing down the piston rod's movement. This increases the piston rod's resistance. When the external electromagnetic induction coil is de-energized, the spherical magnetic particles disperse, thus reducing the piston rod's resistance.

[0039] The production process includes the following steps:

[0040] Step 1: Selection and preparation of metal parts. When selecting metal parts, it is necessary to choose metal parts with strong corrosion resistance.
