Description

Electromagnetic induction structure

Technical Field

The invention belongs to the technical field of electromagnetic induction devices, relates to a technology for improving a damping effect of a damping structure, and particularly relates to an electromagnetic induction structure.

Background

Electromagnetic induction refers to a conductor placed in a changing magnetic flux, and an electromotive force is generated. This electromotive force is called induced electromotive force or induced electromotive force, and if the conductor is closed as a loop, the electromotive force drives electrons to flow, forming an induced current (induced current).

When a strong magnet (which may be an electromagnet or a permanent magnet) and a non-magnetic metal (especially aluminum) are in a relatively static state, the strong magnet and the non-magnetic metal are not repelled and attracted, but when the strong magnet and the non-magnetic metal are in relative motion, induced current is formed in the non-magnetic metal, and a magnetic field which is mutually repelled with the magnetic field of the strong magnet is generated.

Based on this, we found that the damping structure in the prior art has a certain "feel of stagnation" during the damping process. For example, in a door/window system, a damping structure is usually provided on a door (window) body and a door (window) frame, and when the door (window) is closed, the structure of the damping structure located on the door (window) body contacts with the structure located on the door (window) frame to buffer or stop the continued operation of the door/window. In this process, because of the relatively direct hard contact between the structures, the door (window) will stop moving in a very short time, i.e. a sudden stop movement is generated, which will result in the generation of the aforesaid "stagnation feeling", and is specifically shown in: the feedback of the door and window to the user is not desirable to be smooth and fluent. Furthermore, the sudden stop action also causes greater structural losses to the door (window) body and door (window) frame, which can reduce the service life of the door and window system.

Because the cutting speed influences the magnitude of the induced current to a certain extent, and thus indirectly influences the magnitude of the damping force, when the first induction part moves towards the second induction part at a larger speed, the damping force can be increased, and the damping effect between the first induction part and the second induction part is increased. For example, in the practical application process, when a user closes the door and window at a faster speed, the door and window can receive a relatively larger damping force, so that the door and window can be prevented from directly colliding with the door and window frame or the window frame, and further the collision sense when the door and window are closed is effectively weakened or eliminated.

The strength of the counter magnetic field generated by the induction two parts is similar to that of the magnetic field generated by the induction one part. Based on this, in the practical application process, if the user closes door and window with stronger effort, can make the magnitude of damping force be close to aforesaid effort to the effectual effort that resists door body or window body and receive, and then avoid the door and window body to be comparatively strong by stopping, thereby weaken or eliminate the collision sense.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1 to 9, the following embodiments of the present invention are provided:

as shown in fig. 1 to 5, a first embodiment of the present invention proposes an electromagnetic induction structure including:

a sensing part 1 arranged on a structural member A3 needing damping;

the induction two parts 2 are arranged on a structural part B4 which needs to provide damping;

wherein the induction first part 1 is a magnetic part, and the induction second part 2 is a non-magnetic part;

the induction two parts 2 at least form a damping surface 201, when the induction one part 1 approaches to the damping surface 201, the induction two parts 2 generate induced eddy current by the magnetic field of the induction one part 1, and form a magnetic field exclusive to the induction one part 1 so as to form a damping structure between the structural member A3 and the structural member B4.

In the present embodiment, the electromagnetic induction structure is constituted by an induction first portion 1 and an induction second portion 2.

The induction part 1 is a magnetic member, and can be of the following two types.

First, the induction part 1 may be an electromagnet. With this configuration, the electromagnetic induction structure of the present embodiment is more preferable for use in a device or environment that can be powered, such as damping for some mechanical devices.

And secondly, the induction first part 1 can be used as a permanent magnet. It is contemplated that in some devices or environments, it may be difficult or impossible to energize the device or environment, such as in a door or window system. With this structure, the induction part 1 may be a neodymium iron boron permanent magnet material. The magnetic field sensor has higher magnetic induction intensity, magnetic induction coercive force and magnetic energy product.

Therefore, the type of induction section 1 that is relatively optimal may be selected based on the application environment of the electromagnetic induction structure.

On the basis of the above, the induction section 1 is provided on the structural member A3. The structural member A3 is defined as a structure to be damped, for example, when the electromagnetic induction structure is applied to a door and window system, the structural member A3 is a door or window. It can be seen that the nature of the structural member A3 is movable and that this movement is required to be damped.

The induction two parts 2 are made of non-magnetic materials. For example, aluminum may be used. Which is mounted on structure B4. The structural member B4 is defined as a structure that needs to provide damping. For example, when the electromagnetic induction structure is applied to a door and window system, the structural member B4 is a door frame or a window frame. It can be seen that the characteristics of the structural member B4 are relatively fixed to form a relative movement with the structural member A3, so as to achieve that the induction two parts 2 generate induced currents, and in the process that the structural member B4 approaches to the induction two parts, a magnetic field which is repelled from the induction one part 1 is generated. By two mutually repulsive magnetic fields, the damping process between the induction first part 1 and the induction second part 2 is realized, and the damping process between the structural part A3 and the structural part B4 is further realized.

To further illustrate, we performed the following analysis of the damping process for sense one 1 and sense two 2:

First, in the process of inducing the first portion 1 to approach the second portion 2, there is a trigger point, which causes the second portion 2 to generate an induced current by inducing the magnetic field of the first portion 1 and generate a magnetic field (hereinafter referred to as a counter magnetic field for convenience of understanding) mutually exclusive to the induced current. This process represents that the inductive two part 2 starts to provide a repulsive force (hereinafter referred to as damping force for ease of understanding) of the damping process to the inductive one part 1. See the following formula:

wherein delta is induction current, B is magnetic field intensity, L is wire length of the cutting magnetic field, V is speed of the cutting magnetic field, and theta is angle of the cutting magnetic field.

It can be seen that, in one, the induced current is proportional to the magnetic field strength. I.e. the induced current increases, the magnetic field strength increases accordingly and the damping force increases.

Secondly, the induced current can be increased by increasing the relevant parameters. For example, increasing the length L of the wire cutting the magnetic induction line, increasing the cutting speed v, and cutting the magnetic induction line as perpendicularly as possible (θ=90°) can increase the induced current.

Based on this we can get:

1. when the first sensing part 1 approaches to the second sensing part 2, the angle of the cutting magnetic induction line is gradually close to 90 degrees, so that the damping force can be increased as known from the foregoing discussion, that is, the damping effect of the first sensing part 1 and the second sensing part 2 can be gradually increased, so that the first sensing part 1 is gradually damped in a softer and more gentle state, and the stagnation feeling of the damping structure is further weakened or eliminated.

2. Because the cutting speed influences the magnitude of the induced current to a certain extent, and thus indirectly influences the magnitude of the damping force, when the first induction part 1 moves towards the second induction part 2 at a larger speed, the damping force can be increased, and thus the damping effect between the first induction part 1 and the second induction part 2 is increased. For example, in the practical application process, when a user closes the door and window at a faster speed, the door and window can receive a relatively larger damping force, so that the door and window can be prevented from directly colliding with the door and window frame or the window frame, and further the collision sense when the door and window are closed is effectively weakened or eliminated.

3. The strength of the demagnetizing field generated by the induction two sections 2 is approximately the same as that of the magnetic field generated by the induction one section 1. Based on this, as mentioned above, in the practical application process, if the user closes the door and window with a stronger acting force, the damping force will approach the acting force, so as to effectively resist the acting force received by the door or window, and further avoid the door and window from being blocked more strongly, thereby weakening or eliminating the collision sense.

The above discussion is directed to explaining that the magnitude of the damping force of the electromagnetic induction structure has good adaptivity according to a relatively complicated actual situation, and this adaptivity can effectively reduce the collision feeling of the door or window when closed.

Secondly, when the first sensing part 1 transits the trigger point, the second sensing part 2 continuously generates a demagnetizing field and continuously provides damping force for the first sensing part 1 until the speed of the first sensing part 1 slowly drops to 0. In this process, the following two phases are divided:

1. in the process of inducing the speed of the first part 1 to decrease, the intensity of the counter magnetic field generated by the second part 2 is approximately equal to the intensity of the magnetic field of the first part 1 because of the self-adaption. It can be known that another reason for generating the stagnation sensation of the damping structure is that the damping force of the sensing two portions 2 is far greater than the action force of the sensing one portion 1, so that the sensing one portion 1 is caused to stop suddenly, and the stagnation sensation is generated. However, when the damping force generated by the sensing two parts 2 is close to the action force applied to the sensing one part 1, the sensing one part 1 tends to stop in a slow and stable posture, so that the stagnation feeling is eliminated. Based on the above, in the practical application process, the sudden stop state can not occur in the closing process of the door and window, so that a series of adverse effects caused by the sudden stop action are eliminated.

2. When the speed of the induction first part 1 is 0, the demagnetizing field of the induction second part 2 also disappears, and no influence is caused on the induction first part 1.

In summary, the electromagnetic induction structure can eliminate the stagnation feeling to a greater extent in the process of closing the door and window and after the closing of the door and window in the actual application process, especially when being used on the door and window system, so that the door and window is in a stable and gentle state and in a slow stop motion state, the comfort level of the damping structure for the feedback of the user is improved, the mechanical structure of the door and window system is effectively protected, and the service life of the door and window system is prolonged.

As shown in fig. 1 to 4, a second embodiment of the present invention proposes an electromagnetic induction structure, and further includes, on the basis of the first embodiment:

a first adjusting part 5, at least part of the first adjusting part 5 is connected with the induction two parts 2;

wherein, the first adjusting part 5 at least has an adjusting state I and an adjusting state II;

when the first adjusting part 5 is in an adjusting state, the sensing two parts 2 do the motion towards the sensing one part 1 in the vertical direction; and

when the first adjusting part 5 is in the second adjusting state, the second sensing part 2 moves away from the first sensing part 1 in the vertical direction.

In the present embodiment, the first regulating portion 5 is also included.

We have found that the distance between the sensing first part 1 and the sensing second part 2 affects the magnitude of the damping force to some extent. Specifically, when the distance between the two parts increases, the damping effect between the induction one part 1 and the induction two part 2 decreases accordingly, i.e., the damping force decreases. When the distance between the two parts is reduced, the damping effect between the sensing first part 1 and the sensing second part 2 is correspondingly enhanced, i.e. the damping force is increased.

Based on this, the second adjusting portion 8 can adjust the distance to actively adjust the damping force to achieve the damping effect desired by the user.

In the adjustment state, the sensing two parts 2 move towards the sensing one part 1. Namely, the distance between the two is reduced, so that the damping force is increased, and the damping efficiency is further improved.

As divergent, the effect brought about by the adjustment state one is more desirable to be applied in the closing process of the door and window, since it is desirable that the door and window can be closed faster in the aforesaid process, and thus the adjustment state one is more suitable.

In the second adjustment state, the second sensing portion 2 is far from the first sensing portion 1. I.e. the distance between the two is increased, thereby reducing the magnitude of the damping force and further reducing the influence of the damping.

As a divergence, the effect brought by the second adjustment state is more desirable to be applied after the door and window is closed and during the door and window is opened, because the door and window can be opened smoothly only after the damping effect is not generated between the first sensing part 1 and the second sensing part 2. Therefore, the second adjustment state is more suitable.

As shown in fig. 5, a third embodiment of the present invention provides an electromagnetic induction structure, and further includes, based on the previous embodiment:

a command unit 6 provided in the structural member A3;

a second instruction unit 7 connected to the first adjustment unit 5;

when the first sensing part 1 and the second sensing part 2 approach each other, the first command part 6 and the second command part 7 are contacted, so that the second command part 7 links the first adjusting part 5 to the first adjusting state and/or the second adjusting state.

In this embodiment, since the induction first portion 1 has one forward stroke (movement from the point a far from the induction second portion 2 toward the point B near the induction second portion 2) and one reverse stroke (movement from the point B near the induction second portion 2 toward the point a far from the induction second portion 2). Based on this, it is desirable that the sensing two parts 2 be able to recognize different strokes of the sensing one part 1 to adjust to the adjustment state one or the adjustment state two.

Thereby, the instruction one portion 6 and the instruction two portion 7 are added.

The first command part 6 and the second command part 7 trigger different adjustment states of the first adjustment part 5 in a contact manner, so that the states of the second sensing part 2 are influenced in a linkage manner.

Specifically, when the first sensing portion 1 moves in the forward stroke, the first command portion 6 and the second command portion 7 gradually contact, and further trigger the first adjusting portion 5 to be in the first adjusting state, and under the promotion of the first adjusting state, the second sensing portion 2 moves towards the first sensing portion 1. With the foregoing process, the distance between the sensing second part 2 and the sensing first part 1 is reduced, so that the damping effect is improved, that is, the sensing first part 1 is gradually stopped due to a larger damping force. This is what we expect to sense the effect a portion 1 has on a positive stroke.

When the first sensing part 1 is at the end of the forward stroke or the movement needs to enter the reverse stroke, the first command part 6 and the second command part 7 are contacted again, or the part of the first command part 6 is contacted with the second command part 7 again, so that the first adjusting part 5 is transited to the second adjusting state, and under the influence of the second adjusting state, the second sensing part 2 moves away from the first sensing part 1. Similarly, with the foregoing process, the distance between the sensing second part 2 and the sensing first part 1 is increased, so that the damping effect is weakened, and at this time, the sensing first part 1 is easier to enter the back stroke motion.

As shown in fig. 5, a fourth embodiment of the present invention proposes an electromagnetic induction structure, and based on the above embodiment, the instruction part 6 includes at least:

a contact a601 disposed on the structural member A3 and located on one side of the induction part 1;

a contact B602 disposed on the structural member A3 and located on the other side of the induction part 1;

wherein, when the contact member a601 contacts the second command part 7, the second command part 7 links the first adjustment part 5 to an adjustment state one; and when the contact member B602 contacts the second command part 7, the second command part 7 links the first adjustment part 5 to the second adjustment state.

In the present embodiment, as described above, since it is desirable to sense that the part 1 is affected by different degrees of damping in the forward stroke and the reverse stroke, the command part 6 constituting the trigger condition has the contact a601 and the contact B602.

Specifically, the contact a601 and the contact B602 are respectively installed at both sides of the induction section 1 with a certain distance therebetween. When the first sensing portion 1 moves in the forward stroke, the contact member a601 is continuously close to and finally contacts the second command portion 7, and the first adjusting portion 5 enters the first adjusting state, so that the second sensing portion 2 moves towards the first sensing portion 1, and the distance between the two portions is reduced.

At the same time, the induction first part 1 starts to gradually approach the induction second part 2 in the positive stroke direction, i.e. the damping process described above occurs.

Furthermore, when the sensing first portion 1 approaches the end of the positive stroke, the contact B602 is in contact with the second command portion 7, and the first adjusting portion 5 enters the second adjusting state, so that the sensing second portion 2 moves away from the sensing first portion 1, thereby increasing the distance between the two portions.

The specific structure of the second instruction part 7 can be a trigger rod, the upper end of which is in the form of rotary connection and is connected with the first adjustment part.

The contact member a601 may be the structure of the structural member A3 itself, for example, a certain end surface of the structural member A3, which is slightly higher than the lowest point of the trigger lever. When the end face contacts with the trigger rod, the contact rod has swinging property, so that the contact rod can slide relative to the end face and continuously move in a swinging posture. This swinging action triggers the first adjustment part 5 to take place in the adjustment state one. The contact member B602 may be a bump, and the upper end surface is higher than the lowest point of the trigger lever, so as to contact with the trigger lever and enable the swing angle of the trigger lever to be increased, and this process triggers the first adjusting portion 5 to generate the second adjusting state.

When the angle of the trigger lever swinging along the positive stroke direction gradually increases, the first adjusting portion 5 is linked to be in the adjusting state one and the adjusting state two.

In practical applications, such as door and window systems, the contact a601 may be an upper end surface of a door or window, the contact B602 may be disposed in a sliding groove on the upper end surface of the door or window, and the trigger lever may be mounted in a door frame or window frame.

It can be seen that the contact a601 and the contact B602 are respectively in contact with the second command part 7 to trigger the first adjustment part 5 to different adjustment states, so that the influence of the damping effect on the positive stroke of the first sensing part 1 is deepened, and the movement can be stopped in a relaxed state in a short time. And the influence of the damping effect on the back stroke is eliminated, so that the motion of the back stroke can be realized smoothly.

As shown in fig. 1 to 5, a fifth embodiment of the present invention proposes an electromagnetic induction structure, and on the basis of the previous embodiment, the first adjusting portion 5 has at least a first stroke section, and the occurrence of the first stroke section is triggered by the contact a601 and the command two portion 7;

wherein the first adjusting part 5 is configured to perform the first stroke operation at least including:

A pressure driving member 501 connected to the command bipartite 7;

a pressure chamber 502 filled with a pressure medium, and the pressure driver 501 is slidably disposed in the pressure chamber 502;

the pressure transmission part 503 is slidably disposed in the pressure chamber 502 and connected to the sensing two parts 2;

when the second instruction part 7 is actuated, the pressure driving member 501 makes a stroke motion of a first stroke segment in the pressure chamber 502, so as to cause the pressure driving member 503 to drive the second induction part 2 to move toward the first induction part 1 in the vertical direction.

In the present embodiment, the first adjusting part 5 has a first stroke section. The triggering conditions are as follows: the contact a601 is in contact with the command two 7. At this time, the first adjusting part 5 operates in the first stroke section to adjust the first state to urge the sensing two parts 2 to move toward the sensing one part 1.

The above-described structure can be realized to include at least a pressure driving member 501, a pressure chamber 502, and a pressure transmitting member 503.

The pressure driver 501 is connected to the command two 7. Specifically, the pressure driving member 501 may be a structure of a piston rod one, in which a mounting groove is formed at an end portion, and the command two portion 7 is movably connected with the piston rod one through the mounting groove.

The pressure chamber 502 is filled with a pressure medium. The shaft portion of the piston rod one is slidably disposed within the pressure chamber 502. When the second command part 7 contacts with the contact member a601, the contact member a601 causes the second command part 7 to swing, thereby pushing the first piston rod to perform a stroke motion in the first stroke segment. I.e. the pressure medium in the pressure chamber 502 will be compressed.

On the basis of the above, the pressure driving member 501 may be a second piston rod, and the rod body of the second piston rod is slidably connected in the pressure chamber 502, and when the pressure medium is compressed, the second piston rod is pushed to move downwards, so as to push the second sensing portion 2 connected with the second piston rod to move towards the first sensing portion 1, thereby completing the adjustment function of the first adjusting portion 5 on the second sensing portion 2 in the adjustment state.

As shown in fig. 5, a sixth embodiment of the present invention provides an electromagnetic induction structure, and further includes, based on the previous embodiment:

an elastic portion 504 disposed between the pressure driving member 501 and the pressure chamber 502 to provide at least a rebound force to the pressure driving member 501 to perform a return motion of the piston motion; and

and an elastic second portion 505, disposed at an end of the pressure transmission member 503, for providing a rebound force to at least the pressure transmission member 503 to make it perform a return motion of the piston motion.

In this embodiment, the elastic first portion 504 and the elastic second portion 505 are further included.

Since the first adjustment part 5 also has an adjustment state two, i.e. the sensing part 2 needs to be moved away from the sensing part 1, it is desirable to have a part of additional structure to assist the above-mentioned process.

Based on this, an elastic portion 504 is added between the pressure driver 501 and the pressure chamber 502. The resilient portion 504 is capable of providing a force to the return motion of the pressure driver 501 to assist its return to the original state. I.e. releasing the pressure in the pressure chamber 502, thereby completing the transition of the first regulating portion 5 from the first regulating state to the second regulating state.

The pressure transmitting member 503 is provided with an elastic portion 505. Similarly, the elastic second portion 505 can provide a certain force for the return motion of the pressure transmission member 503 to assist the return motion to the initial position, i.e. to drive the sensing second portion 2 connected thereto to return to the initial state (away from the sensing first portion 1).

It should be noted that the elastic first portion 504 and the elastic second portion 505 may be springs. The rate of deformation of the spring need not be too high, i.e., the spring does not to a certain extent over-resist or block the stroke movement of the pressure driver 501 and the pressure driver 503.

As shown in fig. 1 to 5, a seventh embodiment of the present invention proposes an electromagnetic induction structure, and on the basis of the previous embodiment, the first adjusting portion 5 further has a second stroke section, and the occurrence of the second stroke section is triggered by the contact member B602 contacting the command two portion 7;

wherein the structure of the first adjusting part 5 in the second stroke section comprises at least:

a liquid return chamber 506, which is communicated with one end of the pressure chamber 502;

a blocking member 507 disposed in the liquid return chamber 506 via a first elastic member 508;

a circulation chamber 509 having one end communicating with the liquid return chamber 506 and the other end communicating with the pressure chamber 502;

the end of the blocking member 507 has a first contact part 5010, the end of the pressure driving member 501 has a second contact part 5011, and the first contact part 5010 can abut against the second contact part 5011 to form a passage between the liquid return chamber 506 and the pressure chamber 502.

In the present embodiment, the first adjustment part 5 also has a second stroke section. The triggering of the first adjusting part 5 in the second stroke section is due to: contact B602 is in contact with command two 7.

When the contact member B602 contacts the second command portion 7, the swing angle of the second command portion 7 is increased, so that the second command portion 7 continues to push the pressure driving member 501 of the first adjusting portion 5 into the second stroke segment.

On the basis of the above, the first regulating portion 5 further has a liquid return chamber 506, a blocking member 507, and a circulation chamber 509.

The liquid return chamber 506 is in communication with the pressure chamber 502, and may be located at one side of the pressure chamber 502.

The blocking member 507 is mounted in communication with the return chamber 506 and the pressure chamber 502 by a resilient member 508, such as a spring. It may be of a plug structure. The circulation chamber 509 has a liquid inlet communicating with the liquid return chamber 506 and a liquid outlet communicating with the circulation chamber 509 to form a circulation line for the pressure medium.

As shown in fig. 6, a first contact part 5010 and a second contact part 5011 are provided at the end of the stopper 507 and the end of the pressure driving member 501, respectively. The first contact 5010 can be in a convex configuration and the second contact 5011 can be in a rod configuration (the diameter of the rod configuration is much smaller than the diameter of the communication line to avoid the communication line to be blocked by the rod configuration).

On the basis of the above, when the pressure driving member 501 enters the second stroke segment, the first contact part 5010 contacts with the second contact part 5011, and the second contact part 5011 pushes the first contact part 5010 to perform the retracting movement, which opens the communication line between the liquid return chamber 506 and the pressure chamber 502, i.e. is in a passage state, and at this time, the pressure medium in the pressure chamber 502 enters the liquid return chamber 506 and is delivered to the circulation chamber 509. Since the pressure medium in the pressure chamber 502 is released, that is, the pressure is released, the pressure transmission member 503 drives the sensing two parts 2 to rise, that is, the second adjusting state of the first adjusting member drives the sensing two parts 2 to be away from the sensing one part 1, so that the two intervals are increased, and the damping force is reduced.

It should be noted that the resilient member 508 needs to have a certain degree of resistance to avoid compression when the pressure driven member 501 is stroked.

As shown in fig. 1 to 5, an eighth embodiment of the present invention provides an electromagnetic induction structure, and further includes, based on the previous embodiment:

a second adjusting part 8, wherein the second adjusting part 8 is at least partially connected with the induction two part 2;

wherein the second adjusting part 8 at least has an adjusting state three and an adjusting state four;

when the second adjusting part 8 is in the third adjusting state, the curvature of the damping surface 201 of the sensing part 2 is in an increasing trend; and when the second adjusting part 8 is in the adjusting state four, the curvature of the damping surface 201 of the sensing two parts 2 is in a decreasing trend.

In the present embodiment, the second regulating portion 8 is also included.

When the damping surface 201 is in a planar structure, the damping force between the sensing first portion 1 and the sensing second portion 2 has a certain regularity to a certain extent, and the regularity reduces the damping efficiency to a certain extent.

Thus, the damping surface 201 may include an arcuate surface and a planar surface. The arc-shaped surface is used for providing a demagnetizing field firstly so as to reduce the motion situation of the induction part 1 to a large extent. When the motion situation of one part 1 is stable, the plane inherits the damping effect.

Based on this, when the curvature of the arcuate surface changes, the magnitude of the damping force can be affected to some extent. Therefore, it is desirable that the curvature of the arcuate surface can be adjusted to accommodate the aforementioned conditions for different conditions, such as a greater weight of the structural member A3, when a greater damping force is required.

Thus, the second regulating portion 8 is added. It has an adjustment state three and an adjustment state four.

The three purposes of adjusting the state are to increase the curvature of the arc surface so as to improve the influence of the three purposes on the damping force, and the damping force can be increased generally, so that a more powerful damping effect is provided for structural members A3 with larger specifications.

The fourth adjustment state is used for reducing the curvature of the arc-shaped surface so as to reduce the influence of the curvature on the damping force, and generally the damping force can be reduced, so that the damping force provides an adaptive damping effect for structural components A3 with smaller specifications.

As shown in fig. 1 to 5, a ninth embodiment of the present invention proposes an electromagnetic induction structure, and on the basis of the above embodiment, the second adjusting portion 8 includes at least:

a supporting portion 801, where the supporting portion 801 abuts against the damping surface 201, and provides a supporting force in a first direction to the damping surface 201 at a supporting point O1;

A second supporting part 802, wherein the second supporting part 802 is fixedly connected with the damping surface 201;

and a tuning component 803, wherein the first supporting part 801 and the second supporting part 802 are connected to the tuning component 803, and the distance between the first supporting part 801 and the second supporting part 802 is controlled by the tuning of the tuning component 803.

In the present embodiment, a specific structure of one of the second regulating portions 8 is given.

The second adjusting unit 8 is composed of a first supporting unit 801 and a second supporting unit 802.

The strut section 801 abuts against the damping surface 201 at a strut point O1 to provide a strut force in a first direction, which is an upward direction in the drawing, to the damping surface 201. Correspondingly, one end of the supporting two parts 802 is fixedly connected with the damping surface 201, so as to ensure the stability of the second adjusting part 8. In addition, when the sensing two parts 2 move towards or away from the sensing one part 1, the second adjusting part 8 is driven to synchronously act.

On the basis of the above, the first support part 801 and the second support part 802 are both connected to the regulating member 803. By causing the adjustment member 803 to rotate, the distance between the first support portion 801 and the second support portion 802 is changed. Specifically, the first support portion 801 moves toward or away from the second support portion 802, thereby changing the position of the support point O1 and synchronously bringing about a change in the curvature of the damping surface 201.

As shown in fig. 1 to 5, a tenth embodiment of the present invention provides an electromagnetic induction structure, and on the basis of the above embodiment, the regulating member 803 has at least a threaded section 8031 and a smooth section 8032, the supporting two portions 802 are screwed to the threaded section 8031, and the supporting one portion 801 is slidably connected to the smooth section 8032 and is restrained by a retaining member 804.

In this embodiment, the adjustment member 803 may be a threaded rod. The bracing portion 801 may be in the form of a wedge which is slidably connected to the smooth section 8032 of the threaded rod. A stop, i.e., stop 804, is provided on the shaft of the threaded rod on one side of the wedge. The two supporting parts 802 may be L-shaped frames, one end of each L-shaped frame is provided with a threaded hole for screwing with a threaded section 8031 of the threaded rod, and the other end of each L-shaped frame is provided with a connecting rod for connecting with the damping surface 201.

When the damper is adjusted, the threaded rod is rotated to move towards the damping surface 201, the wedge blocks are driven to synchronously act through the stop blocks, the position of the supporting point O1 of the wedge blocks to the damping surface 201 is changed, and then the curvature of the damping surface 201 is increased. Correspondingly, by reversing the rotation of the threaded rod, it is moved away from the damping surface 201, thereby reducing the curvature of the damping surface 201. The above adjustment process corresponds to the third adjustment state and fourth adjustment state of the second adjustment portion 8, and the change in the damping force is achieved by adjusting the curvature of the damping surface 201.

As shown in fig. 7, an eleventh embodiment of the present invention proposes an electromagnetic induction structure, and further includes, on the basis of the above embodiment:

and a compensating structure 9 formed on the damping surface 201, wherein the compensating structure 9 can shape the damping surface 201 from a planar structure to a non-planar structure.

In this embodiment, a compensating construction 9 is also included. The compensating formation 9 serves to shape the planar formation of the damping surface 201 into a non-planar formation. For example, a groove having the same size (depth dimension) (i.e., a peer groove), or a groove having a gradually increasing or decreasing size (depth dimension) (i.e., a step groove). The number or arrangement of the grooves is not particularly limited herein, and the purpose of this embodiment is to: the regularity of the magnetic field of the damping surface 201 is changed by arranging a same level or step groove body on the damping surface 201, so that the damping force is influenced to a certain extent, and finally, a complex demagnetizing field is realized so as to resist the motion situation of the induced part 1.
