Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

An active shock absorber 100 for a vehicle, a control system 1000 for a vehicle, and a vehicle 10000 according to embodiments of the present invention are described below with reference to fig. 1 to 3.

As shown in fig. 1, an active shock absorber 100 for a vehicle according to an embodiment of the present invention includes a damper 110, an elastic member 120, and an electromagnetic assembly 130. The type of the damper 110 is not limited, and may be, for example, a hydraulic damper.

Referring to fig. 1, the damper 110 includes a cylinder 111 and a cylinder rod 112, an axial end of the cylinder 111 is a first end 1111, the cylinder rod 112 penetrates the first end 1111 and is movable relative to the cylinder 111, an end of the cylinder rod 112 away from the cylinder 111 is a second end 1121, the elastic member 120 is disposed between the first end 1111 and the second end 1121, the electromagnetic assembly 130 includes an electromagnetic coil 131 and a permanent magnet 132, the electromagnetic coil 131 is disposed on one of the first end 1111 and the second end 1121, the permanent magnet 132 is disposed on the other of the first end 1111 and the second end 1121, that is, when the electromagnetic coil 131 is disposed on the first end 1111, the permanent magnet 132 is disposed on the second end 1121, and when the electromagnetic coil 131 is disposed on the second end 1121, the permanent magnet 132 is disposed on the first end 1111.

Specifically, electromagnetic coil 131 may generate an electromagnetic force when it is energized, and the electromagnetic force may repel or attract the force generated by the permanent magnet, for example, electromagnetic coil 131 may be connected to current controller 200 described later, current controller 200 may control the circuit to apply a forward current or a reverse current to electromagnetic coil 131, electromagnetic coil 131 may generate an electromagnetic force, one of the forward current and the reverse current may generate an attractive force between electromagnetic coil 131 and permanent magnet 132, and the other of the forward current and the reverse current may generate a repulsive force between electromagnetic coil 131 and permanent magnet 132.

It should be noted that the elastic member 120 may provide a basic rigidity to the active shock absorber 100, and the rigidity may be a capability of the active shock absorber 100 to resist deformation when being pressed, the greater the rigidity of the active shock absorber 100 is, the less the vehicle body 3000 is prone to vibrate, and the smaller the rigidity of the active shock absorber 100 is, the more the vehicle body 3000 is prone to vibrate. For example, the active shock absorber 100 is connected between the control arm 2000 and the vehicle body 3000 of the vehicle 10000, and more specifically, the vehicle body 3000 may be connected to the second end 1121, the control arm 2000 may be connected to an end of the cylinder 111 away from the first end 1111, when the vehicle body 3000 vibrates, the vehicle body 3000 applies pressure to the second end 1121, the cylinder rod 112 moves relative to the cylinder 111 along the first direction F1, the cylinder 111 may apply resistance to the cylinder rod 112 to hinder the cylinder rod 112 from moving, thereby hindering the vehicle body 3000 from moving along the first direction F1, and at the same time, the elastic member 120 may apply resistance to the vehicle body 3000 to hinder the vehicle body 3000 from moving along the first direction F1, so that when no current flows through the electromagnetic coil 131 and no mutual acting force is generated between the electromagnetic coil 131 and the permanent magnet 132, the active shock absorber 100 may also absorb shock for the vehicle.

For example, when the vehicle body 3000 may vibrate due to uneven road surface, acceleration, deceleration, or the like, if the vehicle body 3000 moves along the first direction F1, the current controller 200 may control the circuit to apply a forward current or a reverse current to the electromagnetic coil 131, so that a repulsive force is generated between the electromagnetic coil 131 and the permanent magnet 132, and the repulsive force makes the electromagnetic coil 131 and the permanent magnet 132 tend to move away from each other, because the electromagnetic coil 131 is disposed at one of the first end 1111 and the second end 1121, and the permanent magnet 132 is disposed at the other of the first end 1111 and the second end 1121, thereby the repulsive force may make the cylinder rod 112 move relative to the cylinder tube 111 along the second direction F2, so that the cylinder rod 112 may provide a greater resistance to the vehicle body 3000, and the electromagnetic coil 131 and the permanent magnet 132 cooperate to enhance the damping effect of the active shock absorber 100.

For example, when a driver parks and plays a car game and wants to make the vehicle 10000 have a vibrating game experience, if the vehicle body 3000 needs to move along the first direction F1, the current controller 200 may control the circuit to supply a forward current or a reverse current to the electromagnetic coil 131, so that an attractive force is generated between the electromagnetic coil 131 and the permanent magnet 132, and the attractive force may cause the electromagnetic coil 131 and the permanent magnet 132 to have a tendency to approach each other, because the electromagnetic coil 131 is disposed on one of the first end 1111 and the second end 1121, and the permanent magnet 132 is disposed on the other of the first end 1111 and the second end 1121, the attractive force may cause the cylinder rod 112 to move along the first direction F1 relative to the cylinder tube 111, so that the cylinder rod 112 may provide an assisting force to the vehicle body 3000, and the electromagnetic coil 131 and the permanent magnet 132 cooperate to help the vehicle 10000 generate a vibrating.

In addition, current controller 200 may also control the amount of current passed to solenoid 131, e.g., the greater the current, the greater the attraction or repulsion between solenoid 131 and permanent magnet 132, and the lower the current, the less the attraction or repulsion between solenoid 131 and permanent magnet 132. The greater the repulsion force between electromagnetic coil 131 and permanent magnet 132, the greater the stiffness of active shock absorber 100; the smaller the repulsive force between electromagnetic coil 131 and permanent magnet 132, the smaller the stiffness of active shock absorber 100; the greater the attractive force between electromagnetic coil 131 and permanent magnet 132, the less rigid active damper 100; the smaller the attractive force between electromagnetic coil 131 and permanent magnet 132, the greater the stiffness of active shock absorber 100.

From this, according to the utility model discloses an active bumper shock absorber 100 for vehicle, can change active bumper shock absorber 100's rigidity through the size of the electric current that lets in solenoid 131, thereby can be according to actual conditions, for example the rigidity of adjusting active bumper shock absorber 100 such as road surface condition, with the shock attenuation effect that improves active bumper shock absorber 100, make vehicle 10000 can have more travelling comfort and stability, and can adopt active bumper shock absorber 100 to replace air spring to carry out the shock attenuation, saved the required inflation system of air spring regulation, reduce energy consumption and cost. In addition, the active damper 100 may be used in a variety of situations such as playing a car game, and thus the applicability of the active damper 100 may be increased.

According to some embodiments of the present invention, with reference to fig. 1, first end 1111 and second end 1121 are respectively provided with mounting plate 133, and electromagnetic assembly 130 is fixed to mounting plate 133. Therefore, the electromagnetic assembly 130 can be supported and installed by the installation plate 133, and the installation difficulty of the electromagnetic assembly 130 is reduced. For example, the electromagnetic coil 131 may be embedded in one mounting plate 133, the mounting plate 133 embedded with the electromagnetic coil 131 may be fixedly connected (e.g., welded, etc.) to the first end 1111, the permanent magnet 132 may be embedded in the other mounting plate 133, and the mounting plate 133 embedded with the permanent magnet 132 may be fixedly connected (e.g., connected via screws, etc.) to the second end 1121.

In some embodiments of the present invention, as shown in fig. 1, the elastic member 120 may be a coil spring, and the coil spring is sleeved outside the cylinder rod 112 and is only supported between the two mounting discs 133, i.e. the two ends of the coil spring are respectively supported by the mounting discs 133, and of course, the two ends of the coil spring may be respectively and fixedly connected to the two mounting discs 133, or may not be fixedly connected to each other, and may be set according to actual requirements. Therefore, the spiral spring is convenient to install and sleeved outside the cylinder rod 112, and the cylinder rod 112 can limit the spiral spring, so that the spiral spring can better exert a damping effect. Moreover, the elastic member 120 is located between the two mounting disks 133 and abuts against the two mounting disks 133, when the electromagnetic coil 131 and the permanent magnet 132 have repulsive force, the two mounting disks 133 will be away from each other, and at this time, the two mounting disks 133 can help the elastic member 120 to recover deformation and can increase the rigidity of the active shock absorber 100; when the electromagnetic coil 131 and the permanent magnet 132 attract each other, the two mounting plates 133 approach each other, and at this time, the two mounting plates 133 may compress the elastic member 120 to be deformed, and may reduce the rigidity of the active shock absorber 100.
