DETAILED DESCRIPTION OF THE EMBODIMENTS

[0050] In order to more clearly understand the above objects, features, and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments may be combined with each other.

[0051] In the following description, numerous specific details are set forth to provide a thorough understanding of the present disclosure. However, the present disclosure may be practiced in other ways different from those described herein. Obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all of the embodiments.

[0052] It should be noted that in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article, or device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the said element.

[0053] As Figure 1 and Figure 2 shown, the present application provides a seat. The seat includes a seat cushion 1, a support structure 2, a drive structure 3, and a limit structure 4. The seat cushion 1 is for a user to sit on; the support structure 2 is for supporting the seat cushion 1; the drive structure 3 is for driving the support structure 2 in the vertical direction X to adjust the sitting height of the seat cushion 1; the limit structure 4 is for restricting the position of the support structure 2 in the horizontal direction and keeping the seat cushion 1 within a predetermined position range.

[0054] The interior of the seat cushion 1 has cushioning materials, such as sponge or foam, etc., to ensure the sitting comfort of the seat cushion 1; the outer surface of the seat cushion 1 is covered with fabric material or leather material to ensure the aesthetics of the outer surface of the seat cushion 1.

[0055] The support structure 2 is arranged below the seat cushion 1, and the support structure 2 has a certain stiffness to ensure its support performance.

[0056] The support structure 2, the drive structure 3, and the limit structure 4 are all made of magnetic materials, and through the magnetic fields formed among them, the suspension setting of the support structure 2 and the seat cushion 1 thereon is realized.

[0057] The drive structure 3 is arranged at intervals below the support structure 2 and forms a first magnetic field below the support structure 2. The first magnetic field forms an upward magnetic force to push against the support structure 2 and the seat cushion 1 to suspend above the drive structure 3 through the upward magnetic force.

[0058] Optionally, along the vertical direction X, at least a part of the projection of the support structure 2 falls into the projection of the drive structure 3, so as to ensure that the entire support structure 2 is in the first magnetic field, and ensure that the support structure 2 is uniformly subjected to the magnetic force from the first magnetic field everywhere.

[0059] The limiting structure 4 is arranged at intervals below the support structure 2, and along the vertical direction X, the projection of the limiting structure 4 surrounds the projection of the support structure 2. In this way, a second magnetic field in a ring shape can be formed at the periphery of the support structure 2, and the second magnetic field forms an upward magnetic force, so as to limit the movement of the support structure 2 in the horizontal direction through the upward magnetic force, and keep the support structure 2 and the seat cushion 1 at the center of the second magnetic field, thereby ensuring the stability of the positions of the support structure 2 and the seat cushion 1 in the horizontal direction.

[0060] The seat provided by the embodiment of the present application can form a first magnetic field below the support structure 2 by setting the drive structure 3, and provide an upward magnetic force for the support structure 2 through the first magnetic field, so that the support structure 2 and the seat cushion 1 arranged thereon are suspended above the drive structure 3. By setting the limiting structure 4, a second magnetic field can be formed at the periphery of the support structure 2, and the magnetic force of the second magnetic field can limit the support structure 2 at the periphery in the horizontal direction of the support structure 2, and keep the support structure 2 and the seat cushion 1 arranged thereon within the range of the second magnetic field. In this way, the suspension setting of the seat cushion 1 can be truly realized. When in a bumpy vibration environment, the support structure 2 and the seat cushion 1 will not come into contact and collision with other components, thereby reducing the vibration generated by the support structure 2 and the seat cushion 1 in the bumpy vibration environment and improving the riding experience of the user.

[0061] As Figure 1 and Figure 2 shown, for the seat provided by the present application, wherein, the support structure 2 includes a plurality of first magnets 21, and the plurality of first magnets 21 are arranged at intervals; the drive structure 3 includes a plurality of second magnets 31, and the plurality of second magnets 31 are arranged at intervals;

[0062] Along the vertical direction X, the first magnets 21 and the second magnets 31 are arranged in one-to-one correspondence. In this way, a sub-magnetic field is formed between each first magnet 21 and the relatively arranged second magnet 31, and the magnetic force of the first magnetic field is formed by combining the magnetic forces of each sub-magnetic field.

[0063] The magnetic poles at the upper ends of a part of the second magnets 31 are the same as the magnetic poles at the lower ends of the first magnets 21, and the magnetic poles at the upper ends of a part of the second magnets 31 are opposite to the magnetic poles at the lower ends of the first magnets 21. In this way, an attractive force is formed between a part of the first magnets 21 and the second magnets 31, and a repulsive force is formed between a part of the first magnets 21 and the second magnets 31. Through the mutual cooperation of the attractive force and the repulsive force, the support structure 2 and the seat cushion 1 are kept at an appropriate height.

[0064] Among them, by individually adjusting the magnetic force of each sub-magnetic field, individual adjustment of different positions of the seat can be achieved to meet the riding needs of users in different postures.

[0065] The first magnet 21 is a permanent magnet, and the second magnet 31 is an electromagnet. By adjusting the magnitude of the current passing through the electromagnet, the magnitude of the magnetic force between the first magnet 21 and the second magnet 31 can be adjusted to achieve adjustment of the height of the support structure 2 and the seat cushion 1.

[0066] Such as Figure 1 and Figure 2 As shown, for the seat provided in the present application, among them, the first magnet 21 and the second magnet 31 are both arranged at intervals in a matrix shape, arranged in multiple rows along the first horizontal direction Y, and arranged in multiple columns along the second horizontal direction Z. The first horizontal direction Y is perpendicular to the second horizontal direction Z. The first horizontal direction Y can be the front-back direction of the seat, and the second horizontal direction Z can be the left-right direction of the seat. By arranging the first magnet 21 and the second magnet 31 in a matrix shape, the adjustable points of the support structure 2 can be effectively increased, and the supporting force for the seat cushion 1 can be provided evenly, realizing regular or irregular adjustment of the seat cushion 1.

[0067] Such as Figure 1 and Figure 2 As shown, for the seat provided in the present application, among them, the seat further includes a height detection component. The height detection component is connected to the driving structure 3 and is located between the driving structure 3 and the support structure 2. The height detection component detects the distance between the driving structure 3 and the support structure 2 to indirectly achieve real-time detection of the height of the seat cushion 1.

[0068] Optionally, the height detection component includes a plurality of distance acquisition elements 5. One distance acquisition element 5 is provided at the upper end of each second magnet 31. The distance acquisition element 5 acquires the distance between the second magnet 31 and the corresponding first magnet 21, so that real-time detection of the distance between each first magnet 21 and the corresponding second magnet 31 can be achieved respectively.

[0069] Optionally, the distance acquisition element 5 is a distance sensor or an imaging element. The distance between the first magnet and the corresponding second magnet 31 is directly detected by the distance sensor, or the image between the first magnet 21 and the second magnet 31 is acquired by collecting an image and converted into a specific value.

[0070] Such as Figure 1 and Figure 2As shown, the seat provided by the present application, wherein, every two adjacent first magnets 21 are connected by a flexible connecting rope 22. Through the flexible connecting rope 22, each of the first magnets 21 is connected to form an integral structure, and through the flexible deformation of the flexible connecting rope 22, the position adjustment of a single first magnet 21 within a certain range can be ensured, so as to realize the separate adjustment of the local position of the cushion 1.

[0071] As Figure 1 and Figure 2 shown, the seat provided by the present application, wherein, the cushion 1 includes a plurality of cushion bodies 11. Above each first magnet 21, a cushion body 11 is connected and provided. The cushion bodies 11 are arranged at intervals, so that the cushion 1 includes a plurality of cushion bodies 11. When a single cushion body 11 is adjusted, the positions of other cushion bodies 11 will not be affected. By separately adjusting the positions of each first magnet 21, the positions of each cushion body 11 can be separately adjusted, so as to realize the separate adjustment of different positions of the cushion 1.

[0072] Optionally, the seat provided by the present application, wherein, the seat further includes a plurality of pressure detection elements (not shown in the figure), and a pressure detection element is provided on each cushion body 11. When a user sits on the seat, the pressure detection elements on each cushion body 11 respectively detect the pressure received by the corresponding cushion body 11, so as to adjust the magnetic field force of the sub-magnetic field between each first magnet 21 and the corresponding second magnet 31 according to the pressure received by each cushion body 11, so that each cushion body 11 can be maintained at the required position.

[0073] As Figure 1 and Figure 2 shown, the seat provided by the present application, wherein, the limiting structure 4 includes a plurality of third magnets 41, and the plurality of third magnets 41 are spliced to form an annular structure. The driving structure 3 is arranged inside the annular structure. Similarly, each third magnet 41 can form a sub-magnetic field, and a second magnetic field is formed by the sub-magnetic fields of each of the third magnets 41.

[0074] The magnetic poles at the upper ends of the third magnets 41 are opposite to the magnetic poles at the lower ends of the support structure 2, so that when the support structure 2 moves horizontally in the direction close to the second magnetic field, a repulsive force will be received, so as to push the support structure 2 in the opposite direction, so that the support structure 2 is restricted inside it through the annular second magnetic field, thereby restricting the horizontal displacement of the support structure 2.

[0075] As Figure 1 and Figure 2As shown, the seat provided by the present application, wherein there are four third magnets 41. One of the third magnets 41 extends from the first side of the driving structure 3 along the first horizontal direction Y to the first side of the driving structure 3 along the second horizontal direction Z. One of the third magnets 41 extends from the first side of the driving structure 3 along the second horizontal direction Z to the second side of the driving structure 3 along the first horizontal direction Y. One of the third magnets 41 extends from the second side of the driving structure 3 along the first horizontal direction Y to the second side of the driving structure 3 along the second horizontal direction Z. One of the third magnets 41 extends from the second side of the driving structure 3 along the second horizontal direction Z to the first side of the driving structure 3 along the first horizontal direction Y. That is, the third magnets 41 are all in an arc structure, with a part surrounding one side of the driving structure 3 along the first direction and another part surrounding one side of the driving structure 3 along the second direction. In this way, the magnitude of the magnetic field force at the position where the two directions intersect can be increased, preventing the support structure 2 from moving horizontally to the front left, front right, rear left, and rear right of the seat, resulting in the offset of the seat cushion 1 and affecting the riding experience.

[0076] The seat provided by the present application, wherein the seat further includes an inertial detection element. The inertial detection element is directly or indirectly positioned with the support structure 2. The inertial detection element is used to detect the inertial forces received by the support structure 2 and the seat cushion 1 along the horizontal direction. The specific detection parameters include parameters such as acceleration, rotational movement speed, and rotational movement angle.

[0077] Optionally, the inertial detection element can be directly installed on the support structure 2, the seat cushion 1, or other structural components of the seat, or the inertial detection element can also be provided on the carrier of the seat, such as a vehicle, as long as it is ensured that the inertial detection element is in the same motion environment and has the same inertial forces.

[0078] The seat provided by the present application further includes a control system. The inertial detection element, the height detection component, the pressure detection element, the driving structure 3, and the limiting structure 4 are all electrically connected to the control system. As Figure 3 shown, when the height detection component detects a change in the distance between the first magnet 21 and the second magnet 31 and / or when the pressure detection element detects pressure, the control element will correspondingly adjust the current value passing through the second magnet 31 to adjust the magnetic induction intensity of the first magnetic field, achieving the effect of adjusting the magnetic field force formed by the first magnetic field, so that the support structure 2 and the seat cushion 1 always maintain the required height (for example, the initial height position); as Figure 4 shown, when the inertial detection element detects inertial forces, the control element will correspondingly adjust the current value passing through the third magnet 41 to adjust the magnetic induction intensity of the third magnet 41, achieving the effect of adjusting the magnetic field force formed by the second magnetic field, so that the support structure 2 and the seat cushion 1 always maintain the required horizontal position (for example, the initial horizontal position).

[0079] AsFigure 1 and Figure 2 As shown in Figure 2 , the seat provided by the present application further includes a base 6, and the driving structure 3 is detachably and positionally installed on the base 6. The limiting structure 4 is disposed around the periphery of the base 6. Optionally, the base 6 has an elliptical or circular structure. By providing the base 6, an installation platform is provided for the driving structure 3, and at the same time, an installation reference is set for the limiting structure 4, so that the central axis of the base 6 along the vertical direction X, the central axis of the base 6 along the vertical direction X, and the central axis of the limiting structure 4 along the vertical direction X coincide, improving the overall symmetry of the seat. Thereby improving the overall force uniformity of the seat.

[0080] As Figure 1 and Figure 2 As shown in Figure 2 , the seat provided by the present application includes two support columns 7. The two support columns 7 are spaced apart along the second horizontal direction Z, and the support columns 7 extend along the vertical direction X. The lower ends of the support columns 7 are connected to the base 6, and armrests are connected to the upper ends of the support columns 7 for supporting the elbows of the user. The seat cushion 1, the support structure 2, and the driving structure 3 are all located between the two support columns 7.

[0081] As Figure 1 and Figure 2 As shown in Figure 2 , the seat provided by the present application further includes a backrest 8 for the user's back to lean on. The backrest 8 is respectively connected to the two support columns 7 through connecting columns 9 to achieve reliable installation of the backrest 8.

[0082] In the seat provided by the embodiment of the present application, by arranging the driving structure 3, a first magnetic field can be formed below the support structure 2, and an upward magnetic force is provided for the support structure 2 through the first magnetic field, so that the support structure 2 and the seat cushion 1 disposed thereon are suspended above the driving structure 3. By arranging the limiting structure 4, a second magnetic field can be formed at the periphery of the support structure 2, and the support structure 2 can be limited along the horizontal periphery of the support structure 2 through the magnetic force of the second magnetic field, and the support structure 2 and the seat cushion 1 disposed thereon are kept within the range of the second magnetic field. In this way, the suspension setting of the seat cushion 1 can be indeed realized. When in a bumpy and vibrating environment, according to the bumpy and vibrating acting forces received by the support structure 2 and the seat cushion 1, the magnetic force of the first magnetic field and the magnetic force of the second magnetic field can be adjusted to adaptively adjust the positions of the support structure 2 and the seat cushion 1 in the vertical direction X and the horizontal direction, so as to at least partially offset the inertial displacement generated by the support structure 2 and the seat cushion 1 due to bumpy vibration, thereby reducing the vibration generated by the support structure 2 and the seat cushion 1 in the bumpy and vibrating environment and improving the riding experience of the user.

[0083] The present application also provides a vehicle, wherein the vehicle includes the seat as described above.

[0084] The vehicle provided by the embodiment of the present application has a seat. By arranging a driving structure 3, a first magnetic field can be formed below a supporting structure 2. The first magnetic field provides an upward magnetic force for the supporting structure 2, so that the supporting structure 2 and the cushion 1 arranged thereon are suspended above the driving structure 3. By arranging a limiting structure 4, a second magnetic field can be formed at the periphery of the supporting structure 2. The magnetic force of the second magnetic field can limit the supporting structure 2 along the horizontal periphery of the supporting structure 2, and keep the supporting structure 2 and the cushion 1 arranged thereon within the range of the second magnetic field. In this way, the suspension arrangement of the cushion 1 can be truly realized. When in a bumpy vibration environment, according to the bumpy vibration acting forces received by the supporting structure 2 and the cushion 1, the magnetic force of the first magnetic field and the magnetic force of the second magnetic field can be adjusted to adaptively adjust the positions of the supporting structure 2 and the cushion 1 in the vertical direction X and the horizontal direction, so as to at least partially offset the inertial displacement generated by the supporting structure 2 and the cushion 1 due to bumpy vibration, thereby reducing the vibration generated by the supporting structure 2 and the cushion 1 in the bumpy vibration environment and improving the riding experience of users.

[0085] The present application also provides a control method for a seat. Among them, the seat can be used to control the seat as described above. The control method of the seat includes:

[0086] Obtain the initial position of the cushion 1. The initial position can be adjusted according to the needs of the user. The initial position can be the original position of the cushion 1 when the user does not sit on the seat, or the target position adjusted according to the user's preference after the user sits on the seat.

[0087] According to the initial position of the cushion 1, adjust the magnetic force of the first magnetic field generated by the driving structure 3 and the magnetic force of the second magnetic field generated by the limiting structure 4. Drive the supporting structure 2 to drive the cushion 1 to be suspended above the driving structure 3 by the magnetic force of the first magnetic field, and limit the supporting structure 2 in the horizontal direction by the magnetic force of the second magnetic field, and suspend it at the initial position to complete the initialization suspension of the cushion 1;

[0088] Detect the real-time position of the cushion 1. When there is a relative displacement of the real-time position relative to the initial position, for example, when used in a bumpy vibration environment and the bumpy vibration acting forces received by the supporting structure 2 and the cushion 1 offset or add to the magnetic force of the first magnetic field and the magnetic force of the second magnetic field, adjust the magnetic force of the first magnetic field generated by the driving structure 3 and / or the magnetic force of the second magnetic field generated by the limiting structure 4, so as to adjust the forces received by the supporting structure 2 and the cushion 1 in the vertical direction X and the horizontal direction, so that the supporting structure 2 and the cushion 1 drive the cushion 1 to move to the initial position under the combined action of the magnetic force of the first magnetic field and the magnetic force of the second magnetic field.

[0089] The control method of the seat provided by the present application. Among them, the step of setting the initial position of the cushion 1 specifically includes:

[0090] Obtain the initial height position of the support structure 2 along the vertical direction X; and
