Seat, vehicle, and seat vibration control method

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on March 20, 2024, with application number 202410325116.6 and invention name “Seat, Vehicle and Vibration Control Method of Seat”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of vehicle technology, and in particular to a seat, a vehicle, and a vibration control method for the seat. Background Art

[0003] With the rapid development of science and technology and the economy, more and more people own and use cars. As a means of transportation, cars have brought great convenience to our lives and work, but they have also brought about traffic safety issues. Seat comfort is one of the main factors in car cabin comfort: for drivers, the restrictions on the driver's sitting posture due to the driving task, and the need to maintain a fixed posture for long periods of time during continuous driving are the core causes of riding discomfort and limb fatigue. Fatigue driving is a major risk factor for road traffic accidents and occupational injuries worldwide. Long-term limb fatigue can also lead to musculoskeletal injuries, such as lumbar muscle strain, lumbar disc herniation and other symptoms.

[0004] Application Contents

[0005] Embodiments of the present application provide a seat, a vehicle, and a vibration control method for a seat, which are used to massage a user and relieve the user's fatigue.

[0006] In a first aspect of an embodiment of the present application, a seat is provided, comprising: a seat body; a backrest connected to the seat body; a vibration component installed in an installation space of the seat body, the installation space being an area between a first boundary and a second boundary; the first boundary being a straight line passing through point H of the seat and having a first angle α with the seat surface of the seat body, and the second boundary being a straight line passing through point H of the seat and having a second angle β with the seat surface of the seat body; wherein α≤160°, and β≥120°.

[0007] In the embodiment of the present application, the installation position of the vibration component on the seat body is within the installation space defined by the above-mentioned first boundary and the second boundary. The distance between the installation space and the H point of the seat is small, so that the vibration force of the vibration component installed in the installation space can be transmitted to the H point of the seat, thereby massaging the user's hip point. That is, the installation position of the vibration component in the embodiment of the present application is better, which can effectively alleviate the discomfort and limb fatigue caused by the user maintaining a fixed posture for a long time, improve the user's comfort, reduce the user's musculoskeletal injuries, and reduce the risk of road traffic accidents caused by the driver's limb fatigue.

[0008] In a specific embodiment, the line connecting the installation position of the vibration component on the seat body and the H point of the seat is the installation line of the vibration component, and the angle γ between the installation line and the seat surface of the seat body satisfies: 125°≤γ≤140°. When the installation position of the vibration component on the seat body passes through the above-mentioned installation line, the position of the vibration component is appropriate. When the vibration component vibrates, the vibration force can be more accurately transmitted to the H point of the seat, thereby massaging the user's hip point. That is, the installation position of the vibration component in the embodiment of the present application is better, which can effectively relieve the discomfort and limb fatigue caused by the user maintaining a fixed posture for a long time, improve the user's comfort, reduce the user's musculoskeletal injuries, and reduce the risk of road traffic accidents caused by driver limb fatigue.

[0009] In a specific embodiment, the vibration assembly includes a driving member and a vibration head, and the driving member drives the vibration head to vibrate back and forth along a first direction.

[0010] In a specific embodiment, the first direction of the reciprocating motion of the vibration head passes through the H point of the seat and has an angle δ with the seat surface of the seat body, 40°≤δ≤55°. In this embodiment, δ represents the inclination angle of the first direction of the reciprocating motion of the vibration head relative to the seat body. When δ is too large, the first direction of the vibration of the vibration head is close to perpendicular to the seat surface of the seat body. At this time, the vibration force exerted by the vibration head on the user causes poor user comfort; when δ is too small, the first direction of the vibration of the vibration head is close to parallel to the seat surface of the seat body, and the vibration head has a poor massage effect on the user and cannot effectively relieve the user's fatigue. Therefore, when 40°≤δ≤55°, the inclination angle of the first direction of the reciprocating motion of the vibration head relative to the seat body is moderate, the massage effect on the user is better, and the user's fatigue can be effectively relieved, and the vibration of the vibration head provides high comfort to the user.

[0011] In a specific embodiment, in the initial state of the seat, the backrest and the seat surface of the seat body form an angle θ. The first direction of the reciprocating motion of the vibrating head passes through point H of the seat and forms an angle δ with the seat surface of the seat body, where δ = θ / 2. In this embodiment, when δ = θ / 2, the angle between the first direction and the seat surface of the seat body is equal to the angle between the first direction and the backrest. Determining the angle between the seat surface and the backrest facilitates determining the installation position of the vibrating head on the seat body and the vibration direction.

[0012] In a specific embodiment, the driving member includes a motor and an eccentric wheel, and the eccentric wheel is connected to the output shaft of the motor and the vibration head. When the output shaft of the motor rotates, it can drive the eccentric wheel to rotate at a certain speed, and centrifugal force is generated during the rotation of the eccentric wheel. This centrifugal force causes the output shaft of the motor to drive the eccentric wheel to move. Since the housing of the motor is fixed to the seat body, the movement of the eccentric wheel driven by the motor is restricted, generating vibration, thereby driving the vibration head to vibrate through the eccentric wheel. The vibration assembly of this embodiment is driven by the motor, so that the vibration frequency of the vibration head can be higher, that is, high-frequency vibration can be achieved.

[0013] In a specific embodiment, the seat further includes a covering layer, which covers the seat body and the vibration component, and the minimum distance L1 between the vibration component and the inner wall of the covering layer is 5mm-30mm. When the minimum distance L1 between the vibration component and the inner wall of the covering layer is too small, the user sits on the chair surface and the covering layer is compressed, resulting in too small a distance between the vibration component and the user, and the covering layer cannot play a buffering role, resulting in poor user comfort during the vibration of the vibration component. When the minimum distance L1 between the vibration component and the inner wall of the covering layer is too large, the vibration force exerted on the user by the vibration component is too small and cannot be effectively massaged. When the minimum distance L1 between the vibration component and the inner wall of the covering layer is 5mm-30mm, when the user sits on the chair surface, the covering layer will not be excessively compressed, resulting in poor user comfort when the vibration component vibrates, and the covering layer can play a massaging role to relieve user fatigue.

[0014] In one specific embodiment, the chair includes at least two vibration assemblies spaced apart along the second direction, and the distance L2 between two adjacent vibration assemblies along the second direction is 150 mm to 250 mm. In this embodiment, the distance L2 between the two vibration assemblies of the chair is suitable for most users. That is, when L2 is within this range, the two vibration assemblies can massage the user's two hip points respectively.

[0015] In one specific embodiment, the chair body is provided with at least two vibration assemblies spaced apart along a second direction. The chair also includes an adjustment assembly for driving the vibration assemblies to change the distance between the vibration heads of two adjacent vibration assemblies along the second direction. Adjustment by the adjustment assembly allows the two vibration assemblies to massage the hip points of users with different body shapes, making the chair suitable for users of varying body shapes and providing a good massage effect for all users.

[0016] In a specific embodiment, the vibration assembly is mounted on the rear cross member of the seat body.

[0017] In a specific embodiment, the vibration component is mounted on the frame of the seat body.

[0018] In a specific embodiment, the seat further includes a control module, which is used to control the vibration component to vibrate or stop vibrating, and to control the vibration frequency of the vibration component, so that the seat can be in a working mode required by the user.

[0019] A second aspect of an embodiment of the present application provides a vehicle, comprising a vehicle body and seats thereon.

[0020] A third aspect of an embodiment of the present application provides a seat vibration control method, wherein the seat is the above seat, and the seat vibration control method includes:

[0021] After receiving a first start instruction from the user, the vibration component is controlled to vibrate at a first frequency.

[0022] In this embodiment, the vibration component vibrates under the control of the user's first start instruction, thereby massaging the user and placing the seat in the first working mode to relieve the user's fatigue. It can effectively alleviate the discomfort and limb fatigue caused by the user maintaining a fixed posture for a long time, improve the user's comfort, reduce the user's musculoskeletal injuries, and reduce the risk of road traffic accidents caused by the driver's limb fatigue.

[0023] In one specific embodiment, upon receiving a signal indicating that the user is fatigued and a first start instruction from the user, the vibration component is controlled to vibrate at a first frequency. When fatigue is detected, the user can proactively activate the first operating mode to alleviate fatigue.

[0024] In a specific embodiment, after the vehicle is parked and a first start instruction is received from the user, the vibration component is controlled to vibrate at the first frequency. In this embodiment, after the vehicle is parked, the user can actively start the first working mode to relieve the user's fatigue.

[0025] In a specific embodiment, the vibration component is controlled to vibrate at a first frequency for a first preset time. The control module of the seat can not only control the vibration component to vibrate at the first frequency according to the user's first start instruction, but also control the vibration time of the vibration component according to the user's instruction, so that the vibration component stops vibrating after vibrating for the first preset time, and the user actively ends the above-mentioned first working mode.

[0026] In one specific embodiment, upon receiving a first stop instruction from the user, the vibration component is controlled to stop vibrating. The chair's control module can not only control the vibration component to vibrate at the first frequency according to the user's first start instruction, but also control the vibration component to stop vibrating according to the user's first end instruction, allowing the user to actively end the first operating mode.

[0027] In a specific embodiment, the vibration control method of the seat further includes: after receiving a second start instruction from the user, controlling the vibration component to vibrate with the music; after receiving a second stop instruction from the user, controlling the vibration component to stop vibrating.

[0028] The chair also has a second operating mode. When the chair's control module receives a second start command from the user, it can control the vibration component to vibrate in sync with the music played by the speakers. This means the vibration component can massage the user in sync with the music, relieving fatigue and enhancing the entertainment experience. The chair's vibration control module can control the vibration component to have a frequency that is the same as or close to the music played by the speakers, further enhancing the entertainment experience.

[0029] In a specific embodiment, the seat vibration control method further includes: upon receiving a signal indicating that the vehicle is in a dangerous state, controlling the vibration component to vibrate at a second frequency; wherein the first frequency is lower than the second frequency.

[0030] In this embodiment, the vehicle can also be equipped with an autonomous driving solution (hereinafter referred to as ADS), which is connected to the control module signal of the seat. When the vehicle is in automatic driving mode under the control of the ADS system, if the ADS system detects that the vehicle is in a dangerous working condition (for example, the vehicle is driving on a bumpy road, the vehicle is driving on a congested road, etc.), the driver needs to be reminded to take over the driving. The control module of the seat can receive the control instruction of the ADS system, and convert the control instruction into an electrical signal and send it to the vibration component to control the vibration component to start vibrating and control the vibration component to vibrate at a second frequency. At this time, the seat is in the third working mode. The second frequency of the seat vibrating in the third working mode is greater than the first frequency of the seat vibrating in the first working mode. That is, when the ADS system detects that the vehicle is in a dangerous working condition, the vibration frequency of the vibration component is higher, so that the driver can be quickly reminded to take over the driving, thereby improving the safety of the vehicle.

[0031] In a specific embodiment, after the vibration component vibrates at the second frequency, the vibration control method of the seat further includes the following steps:

[0032] After receiving the third stop instruction from the user, the vibration component is controlled to stop vibrating.

[0033] In this embodiment, when the seat is in the third operating mode, the seat control module receives a start command from the ADS system and controls the vibration component to vibrate at the second frequency, thereby waking the driver. When the driver takes over driving, they can send a third stop command to the seat control module. Upon receiving the third stop command from the user, the seat control module controls the vibration component to stop vibrating. In other words, the seat control module can not only control the vibration component to vibrate at the second frequency in response to the ADS system's start command, but can also control the vibration component to stop vibrating in response to the user's third stop command, allowing the user to actively terminate the third operating mode.

[0034] In one specific embodiment, when the vehicle is detected to be in a dangerous state, the vibration component is controlled to vibrate at the second frequency for a second preset time and then stop vibrating. That is, the seat control module can not only control the vibration component to vibrate at the second frequency according to the start instruction of the ADS system, but also control the vibration time of the vibration component so that the vibration component stops vibrating after the second preset time, thereby terminating the third operating mode.

[0050] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0051] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0052] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0053] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described based on the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also be indirectly connected to the other element "on" or "under" through an intermediate element.

[0054] As shown in Figure 1, Figure 1 is a schematic structural diagram of a specific embodiment of the seat provided in this application. The seat includes a backrest 1 and a seat body 2 connected to each other. Figure 1 shows the skeleton of the seat body 2 and the skeleton of the backrest 1, but does not show the covering layer and safety belt structures of the two. The backrest 1 can rotate relative to the seat body 2, so that the angle between the backrest 1 and the seat surface of the seat body 2 can be changed to meet the user's various needs, such as lying down and sitting postures.

[0055] In the initial position, the seat body 2's seat surface is horizontal, placing the user's thighs in a horizontal position. The seat body 2 can rotate relative to the backrest 1, reducing the angle between them and allowing the seat body 2's seat surface to move to a non-horizontal position. Furthermore, the seat body 2 can be raised or lowered relative to the backrest 1 to accommodate users of varying heights.

[0056] When users sit in a chair for extended periods, maintaining a fixed posture can lead to discomfort and physical fatigue. To improve user comfort, a vibration component capable of massaging can be added to the chair. For example, a vibration component can be embedded within the seat body 2 of the chair, providing a massage function to alleviate user fatigue. However, if the vibration component is improperly positioned within the seat body 2, the massage effect is poor and cannot effectively alleviate user fatigue after extended sitting.

[0057] The embodiment of the present application improves the massage effect of the seat by reasonably setting the position of the vibration component in the seat body 2, thereby relieving the user's fatigue after long-term riding.

[0058] Figure 2 is a schematic structural diagram of the seat provided in this application in another specific embodiment. As shown in Figure 2, the seat body 2 is equipped with a vibration component 3, which can be installed on the rear crossbeam 21 of the frame of the seat body 2, or can be installed at other positions of the frame of the seat body 2, and embedded in the covering layer of the seat body 2. The vibration component 3 can be installed on the seat body 2 at the position described below. Please refer to Figure 3, which is a schematic diagram of a user sitting on the seat shown in Figure 2. The installation space of the vibration component 3 on the seat body 2 is shown in Figure 3. The installation space is the area between the first boundary (as shown by the dotted line in Figure 3) and the second boundary (as shown by the dotted line in Figure 3). Among them, the first boundary is a straight line passing through the H point of the seat and having a first angle α with the seat surface of the seat body 2, and the second boundary is a straight line passing through the H point of the seat and having a second angle β with the seat surface of the seat body 2.

[0059] The H-point is a reference point used to determine the user's position in the seat. The H-point of the seat is specifically the rotation point (hip point) where the user's torso and thighs connect. The seat has two H-points, and the line connecting the two H-points is horizontal. That is, as shown in Figure 3, the line connecting the two H-points extends in a horizontal direction perpendicular to the paper. After the user takes the seat, most of the body weight is applied to the seat cushion of the seat body 2 through the buttocks, part is borne by the backrest 1 through the back, and part is applied to the steering wheel and floor through the left hand, right hand, and feet. In this sitting position, the movement of the upper part of the user's body during operation is rotation around the axis passing through the two H-points (that is, around the line connecting the two H-points mentioned above). When designing the seat, after the H-point is determined based on the three-dimensional coordinate system of the entire vehicle, the position of the H-point does not change with the user's height and weight characteristics.

[0060] It should be noted that the first boundary and the second boundary are boundary lines passing through the same point H.

[0061] The seat surface of the seat body 2 refers to the surface of the seat body 2 on which the user sits. The seat body 2 has an initial state, which can be the position of the seat body 2 when the vehicle leaves the factory. In this initial state, the seat body 2 is in its lowest position and its seat surface is horizontal. In addition to the initial position, the seat body 2 can also have a first position (not shown) and a second position, as shown in Figure 4. Figure 4 is a schematic diagram of the seat body 2 rotating upward relative to the initial state. When the seat is adjusted upward relative to the initial position (to the first position), the seat body 2 and the backrest 1 move upward synchronously. During this process, the seat surface of the seat body 2 and the vibration assembly mounted thereon rise accordingly. After the above adjustment, the seat surface of the seat body 2 remains horizontal, and the seat surface of the seat body 2 after adjustment is higher than the seat surface of the seat body 2 in the initial state, the mounting position of the vibration assembly after adjustment is higher than the mounting position of the vibration assembly in the initial state, and the height of the backrest 1 after adjustment is higher than the height of the backrest 1 in the initial state. In this first position, due to the overall adjustment of the seat, the position of the vibration assembly relative to the seat body 2 remains the same as in the initial position.

[0062] As shown in Figure 4, when the seat is in the initial state, the seat body 2 is shown as the dotted line in Figure 4. When the seat is tilted upward (in the second position), the seat body 2 is shown as the solid line in Figure 4. During this process, the seat surface of the seat body 2 is tilted upward. After the above adjustment, the seat surface of the seat body 2 is no longer horizontal, but tilted upward, and has an angle with the seat surface of the seat body 2 in the initial state.

[0063] It should be noted that the first angle α between the first boundary and the seat surface of the seat main body 2 mentioned above refers to the angle between the first boundary and the seat surface at the lowest position, that is, the first angle α between the first boundary and the seat surface of the seat main body 2 refers to the angle between the first boundary and the seat surface of the seat main body 2 when the seat is in the initial state; similarly, the second angle β between the second boundary and the seat surface of the seat main body 2 mentioned above refers to the angle between the second boundary and the seat surface at the lowest position, that is, the second angle β between the second boundary and the seat surface of the seat main body 2 refers to the angle between the second boundary and the seat surface of the seat main body 2 when the seat is in the initial state.

[0064] In a specific embodiment, as shown in FIG3 , the first angle α and the second angle β satisfy the following conditions: α ≤ 160°, β ≥ 120°. For example, the first angle α can be 160°, 155°, 150°, 145°, 140°, etc., and the second angle β can be 120°, 125°, 130°, 135°, 140°, etc. The vibration assembly 3 is installed on the seat body 2 within the installation space defined by the first and second boundaries. The distance between the installation space and the H-point of the seat is small, allowing the vibration force of the vibration assembly 3 installed in the installation space to be transmitted to the H-point of the seat, thereby massaging the user's hip point. In other words, the vibration assembly 3 in this embodiment of the present application is installed in an optimal position, effectively alleviating the discomfort and limb fatigue caused by the user maintaining a fixed posture for a long time, improving the user's comfort, reducing musculoskeletal injuries, and reducing the risk of road traffic accidents caused by driver limb fatigue.

[0065] It should be noted that the installation location of the vibration assembly 3 within the installation space defined by the first and second boundaries does not mean that the entire structure of the vibration assembly 3 is located within the installation space. It is sufficient as long as at least a portion of the structure of the vibration assembly 3 can vibrate within the installation space. For example, when the vibration assembly 3 includes a vibrating member and a vibrating member that drives the vibrating member to vibrate, at least a portion of the structure of the vibrating member vibrates within the installation space, and the driving member 31 can be located outside the installation space.

[0066] In one specific embodiment, as shown in FIG3 , the line connecting the mounting position of the vibration assembly 3 on the seat body 2 and the H point of the seat is the mounting line of the vibration assembly 3 . The angle between the mounting line and the seat surface of the seat body 2 is a third angle γ, satisfying the following: 125°≤γ≤140°. For example, the angle γ between the mounting line of the vibration assembly 3 and the seat surface can be 125°, 130°, 135°, 140°, etc. When the mounting position of the vibration assembly 3 on the seat body 2 passes through the aforementioned mounting line, the vibration assembly 3 is properly positioned. When the vibration assembly 3 vibrates, the vibration force can be more accurately transmitted to the H point of the seat, thereby massaging the user's hips. In other words, the mounting position of the vibration assembly 3 in this embodiment of the present application is more optimal, effectively alleviating the discomfort and limb fatigue caused by the user maintaining a fixed posture for a long time, improving user comfort, reducing musculoskeletal injuries, and reducing the risk of road traffic accidents caused by driver limb fatigue.

[0067] In one specific embodiment, Figure 5 is a schematic diagram of the structure of the vibration assembly 3 in Figure 2 . As shown in Figure 5 , the vibration assembly 3 may include a driver 31 and a vibration head 32 . The driver 31 may be mounted to the rear crossbeam 21 of the seat body 2 , or alternatively, to other locations within the seat body 2 , such as the frame of the seat body 2 . When in operation, the driver 31 drives the vibration head 32 to reciprocate, thereby causing the vibration assembly 3 to vibrate.

[0068] Please refer to Figures 6 and 7, Figure 6 is a top view of Figure 5, and Figure 7 is a cross-sectional view taken along the AA line of Figure 6. In the embodiment shown in Figure 7, the driving member 31 can include a motor 311 and an eccentric wheel 312, wherein the output shaft of the motor 311 is connected to the eccentric wheel 312, and the eccentric wheel 312 is also connected to the vibration head 32. When the output shaft of the motor 311 rotates, it can drive the eccentric wheel 312 to rotate at a certain speed, and centrifugal force is generated during the rotation of the eccentric wheel 312. This centrifugal force causes the output shaft of the motor 311 to drive the eccentric wheel 312 to move. Since the housing of the motor 311 is fixed to the seat body 2, the movement of the eccentric wheel 312 driven by the motor 311 is restricted, generating vibration, thereby driving the vibration head 32 to vibrate through the eccentric wheel 312. The vibration assembly 3 of this embodiment is driven by the motor 311, so that the vibration frequency of the vibration head 32 can be high, for example, up to 20Hz-50Hz, that is, high-frequency vibration can be achieved.

[0069] In other embodiments, the vibration component 3 may also be other structures, for example, it may be a vibrator installed on the seat body 2. The present application does not limit the specific structure of the vibration component 3.

[0070] FIG8 is a side view of FIG2. As shown in FIG8, when the vibration assembly 3 includes the aforementioned driving member 31 and the vibration head 32, the driving member 31 is capable of driving the vibration head 32 to reciprocate along a first direction, i.e., the vibration direction of the vibration head 32 is along the first direction shown in FIG8, which is a direction inclined relative to the seat surface of the seat body 2 and toward the seat surface of the seat body 2 for the user to sit on (the outer surface of the seat body 2).

[0071] Continuing to refer to Figure 9, Figure 9 is a schematic diagram of a user sitting on the seat shown in Figure 8. In this embodiment, after the vibration component 3 is installed on the seat body 2, the installation position of the vibration head 32 on the seat body 2 is located within the above-mentioned installation space, and the first direction of the reciprocating motion of the vibration head 32 passes through the H point of the seat, that is, the reverse extension line of the first direction of the reciprocating motion of the vibration head 32 is also located between the first boundary and the second boundary, ensuring that the vibration force of the vibration component 3 can be transmitted to the H point of the seat, and then can massage the user's hip point, effectively relieving the user's fatigue. In this embodiment, since the vibration head 32 vibrates along its axial direction, the installation line of the vibration head 32 and the first direction of the reciprocating motion of the vibration head 32 are located on the same straight line, that is, the installation line of the vibration head 32 is the reverse extension line of the first direction.

[0072] In a specific embodiment, an angle δ is formed between the first direction of reciprocating motion of the vibrating head 32 and the seat surface of the seat body 2, and the angle δ is 40°≤δ≤55°. For example, δ can be 40°, 45°, 48°, 50°, 52°, 55°, etc.

[0073] In this embodiment, δ represents the inclination angle of the first direction of the reciprocating motion of the vibration head 32 relative to the seat body 2. When δ is too large, the first direction of vibration of the vibration head 32 is nearly perpendicular to the seat surface of the seat body 2. At this time, the vibration force exerted by the vibration head 32 on the user causes poor user comfort; when δ is too small, the first direction of vibration of the vibration head 32 is nearly parallel to the seat surface of the seat body 2, and the vibration head 32 has a poor massage effect on the user and cannot effectively relieve the user's fatigue. Therefore, when 40°≤δ≤55°, the inclination angle of the first direction of the reciprocating motion of the vibration head 32 relative to the seat body 2 is moderate, the massage effect on the user is better, the user's fatigue can be effectively relieved, and the vibration of the vibration head 32 provides a high level of user comfort.

[0074] In another specific embodiment, in the initial state of the seat, there is an angle θ between the seat surface of the seat main body 2 and the backrest 1. Since the backrest 1 can rotate relative to the seat main body 2, the angle θ can be increased. In the embodiment of the present application, in the initial state, the angle θ between the seat surface of the seat main body 2 and the backrest 1 is the minimum angle between the seat surface of the seat main body 2 and the backrest 1. Among them, the first direction of the reciprocating motion of the vibration head 32 passes through the H point of the seat and has an angle δ with the seat surface of the seat main body 2, δ = θ / 2. In this embodiment, when δ = θ / 2, the angle between the first direction and the seat surface of the seat main body 2 is equal to the angle between the first direction and the backrest 1. When determining the angle between the seat surface of the seat main body 2 and the backrest 1, the installation position and vibration direction of the vibration head 32 on the seat main body 2 can be conveniently determined.

[0075] In the above embodiments, Figure 10 is a schematic diagram of a user sitting on the seat shown in Figure 8. The seat body 2 may further include a covering layer 22, which covers the frame of the seat body 2 and the vibration component 3, so that the vibration component 3 is embedded in the seat body 2. When the vibration component 3 vibrates, the vibration force is transmitted to the user through the covering layer 22, thereby massaging the user. The minimum distance L1 between the vibration component 3 and the inner wall of the covering layer 22 is the minimum distance between the vibration component 3 and the inner wall of the covering layer 22 when the user is not sitting on the seat, that is, the minimum distance between the vibration component 3 and the inner wall of the covering layer 22 when the covering layer 22 is not compressed. When the user sits on the chair surface, the covering layer 22 is compressed toward the inside of the seat, so that the covering layer 22 is close to the vibration component 3. At this time, the minimum distance between the vibration component 3 and the inner wall of the covering layer 22 is less than L1.

[0076] The minimum distance L1 between the vibration component 3 and the inner wall of the coating layer 22 is 5 mm to 30 mm. For example, the minimum distance L1 between the vibration component 3 and the inner wall of the coating layer 22 can be 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, etc.

[0077] When the minimum distance L1 between the vibration component 3 and the inner wall of the covering layer 22 is too small, the user sits on the chair surface and the covering layer 22 is compressed, resulting in the distance between the vibration component 3 and the user being too small. The covering layer 22 cannot play a buffering role, resulting in poor user comfort during the vibration of the vibration component 3. When the minimum distance L1 between the vibration component 3 and the inner wall of the covering layer 22 is too large, the vibration force exerted on the user by the vibration component 3 is too small and cannot effectively massage. When the minimum distance L1 between the vibration component 3 and the inner wall of the covering layer 22 is 5mm-30mm, when the user sits on the chair surface, the covering layer 22 will not be excessively compressed, resulting in poor user comfort when the vibration component 3 vibrates, and it can play a massage role to relieve user fatigue.

[0078] When a user sits on the chair shown in FIG10 , the cover layer 22 is compressed. At this time, the minimum distance between the vibration component 3 and the inner wall of the cover layer 22 can be 0-25 mm. For example, considering the body shape of a Chinese person, when a user with a height of 175 cm and a weight of 75 kg sits on the chair, the minimum distance between the vibration component 3 and the inner wall of the cover layer 22 can be 0-15 mm.

[0079] In the embodiment shown in Figure 10, when the vibration component includes a driving member and a vibration head 32 connected to the driving member, the minimum distance L1 between the vibration component and the inner wall of the covering layer 22 is: the minimum distance between the vibration head 32 and the inner wall of the covering layer 22 along the first direction of vibration of the vibration head 32.

[0080] Please refer to Figures 11 and 12. Figure 11 is a top view of Figure 2, and Figure 12 is a front view of Figure 5. As shown in Figure 11, the seat body 2 is provided with at least two vibration assemblies 3 spaced apart along the second direction, and the at least two vibration assemblies 3 are symmetrically arranged with respect to the centerline of the seat body 2. The at least two vibration assemblies 3 are positioned in the same positions as described in the above-mentioned embodiments.

[0081] In a specific embodiment, as shown in FIG12 , the distance L2 between two adjacent vibration assemblies 3 along the second direction is 150 mm to 250 mm. For example, L2 can be 150 mm, 170 mm, 180 mm, 200 mm, 210 mm, 220 mm, 230 mm, 240 mm, 250 mm, etc. The distance L2 between the two vibration assemblies of the chair in this embodiment is suitable for most users. That is, within this range, the two vibration assemblies 3 can massage the user's two hip points respectively.

[0082] In a specific embodiment, considering the Chinese body shape standard, the distance L2 between two adjacent vibration components 3 along the second direction can be 200 mm.

[0083] In another specific embodiment, the chair may further include an adjustment component (not shown in the figure), which is used to drive the vibration component 3 to move so as to change the distance L2 between two adjacent vibration components 3 along the second direction. After adjustment by the adjustment component, the two vibration components can massage the hip points of users with different body shapes, so that the chair can be suitable for users with different body shapes and have a good massage effect on users with different body shapes.

[0084] In one specific embodiment, the adjustment assembly may include a screw slider mechanism. In another specific embodiment, the adjustment assembly may include a telescopic cylinder. The adjustment assembly may also be other mechanisms capable of achieving linear motion of the vibration assembly 3 along the second direction. The specific structure of the adjustment assembly is not limited in this application.

[0085] In the embodiment shown in Figure 12, when the vibration component 3 includes a driving member 31 and a vibration head 32, the vibration head 32 can be circular, and its diameter D can be 40mm. When the user sits on the seat, the contact area between the vibration head of this shape and the user's buttocks (the vibration head and the user's buttocks are in indirect contact through the covering layer) is larger, so that the user feels more comfortable when the vibration head vibrates. The linear stroke of the vibration head 32 can be 7.5mm, that is, the maximum distance that the vibration head 32 moves along the first direction is 7.5mm. The height H of the vibration component is the distance between the installation position of the vibration component on the seat body and the end of the vibration head. H is related to the installation position of the vibration component and the thickness of the covering layer. It can be arranged according to actual needs so that the distance L1 between the vibration head and the inner wall of the covering layer satisfies the above relationship.

[0086] The driving member 31 may be a motor. In a specific embodiment, the input rated voltage of the driving member 31 may be 12 V and the rated current may be 2 A. The vibration frequency of the vibration head 32 may be 0-50 Hz.

[0087] In each of the above embodiments, the seat may further include a control module, which may be a seat controller capable of converting control instructions into electrical signals and transmitting them to the vibration assembly, enabling the vibration assembly to execute the corresponding control instructions. The control module is configured to control the vibration assembly to vibrate or stop vibrating, and to control the vibration frequency of the vibration assembly, causing the vibration assembly to vibrate or stop vibrating in response to control instructions from the user or the vehicle's control system, and to vibrate at a set frequency based on different usage requirements.

[0088] When the seat includes an adjustment component, the control module can also be used to control the adjustment component to operate or stop operating, so that the vibration component moves a preset distance along the second direction.

[0089] The embodiments of the present application also provide a vehicle comprising the seat described in any of the above embodiments. The vehicle body may be provided with a display screen, which can be used for display and touch control. The user can issue control instructions to the control module of the seat through the display screen. The control module converts the control instructions into electrical signals and sends them to the vibration component of the seat, causing the vibration component to execute the control instructions. The vehicle may also be provided with a voice system. The user can issue control instructions to the control module of the seat through the voice system. The control module converts the control instructions into electrical signals and sends them to the vibration component of the seat, causing the vibration component to execute the control instructions. The vehicle may also be provided with a switch. The user can issue control instructions to the control module of the seat through the switch. The control module converts the control instructions into electrical signals and sends them to the vibration component of the seat, causing the vibration component to execute the control instructions.

[0090] In one specific embodiment, the vehicle may also be equipped with an Autonomous Driving Solution (ADS), which includes multiple sensors, chips, and other components for enabling autonomous driving. The ADS is signal-connected to the seat control module, meaning the seat control module can interact with the ADS to enable the seat's vibration function during autonomous driving.

[0091] The present application also provides a vibration control method for a seat, wherein the seat is the seat described in any of the above embodiments, and the vibration control method for the seat comprises the following steps:

[0092] After receiving a first start instruction from the user, the vibration component is controlled to vibrate at a first frequency.

[0093] In this embodiment, the vibration component vibrates under the control of the user's first start instruction, thereby massaging the user and placing the seat in the first operating mode to relieve the user's fatigue. Therefore, the first operating mode is a mode actively started by the user.

[0094] Figure 13 is a schematic diagram illustrating signal transmission between various modules of the seat provided herein when in its first operating mode. The arrows in Figure 13 indicate the direction of signal transmission. A user's first start command can be transmitted to the seat's control module via at least one of the display screen, voice system, or switch described above. The control module converts the first start command into an electrical signal and transmits it to the vibration assembly, controlling the vibration assembly to vibrate at a first frequency.

[0095] In one specific embodiment, the chair control method includes: upon receiving a first start instruction from the user indicating that the user is fatigued, and controlling the vibration component to vibrate at a first frequency. In this case, upon recognizing that the user is fatigued, the user can proactively activate the first operating mode to alleviate the user's fatigue.

[0096] The vehicle may also be equipped with an identification system for determining whether the user is fatigued, such as a facial recognition system or a bio-signal monitoring system. The facial recognition system can determine whether the user is fatigued by monitoring the user's facial features, while the bio-signal monitoring system can sense data such as the user's heart rate to determine whether the user is fatigued based on the monitoring results. The seat control module can receive the identification system's determination results.

[0097] In this embodiment, the first operating mode can be started while the vehicle is traveling.

[0098] In another specific embodiment, the control method of the seat specifically includes: after parking and receiving a first start instruction from the user, controlling the vibration component to vibrate at a first frequency.

[0099] In this embodiment, after parking, the user can actively start the first working mode to relieve the user's fatigue. During the process of starting the first working mode, the signal transmission between the modules is shown in FIG13 .

[0100] In one specific embodiment, after receiving a first start instruction from the user, the vibration component is controlled to vibrate at a first frequency for a first preset time and then cease. Specifically, the seat's control module not only controls the vibration component to vibrate at the first frequency according to the user's first start instruction, but also controls the duration of the vibration component's vibration according to the user's instruction, causing the vibration component to cease after the first preset time, thus terminating the first operating mode proactively. The signal transmission between the various modules during the process of terminating the first operating mode is shown in Figure 11.

[0101] The first preset time may be a time set by the user via a display screen, a voice system, or a switch. For example, the first preset time may be set to vibrate for 2-3 minutes every 10 minutes, or vibrate for 3-5 minutes after parking.

[0102] In another specific embodiment, after receiving a first start instruction from the user to control the vibration component to vibrate at a first frequency, the first stop instruction from the user is then received to control the vibration component to stop vibrating. Specifically, the seat's control module can not only control the vibration component to vibrate at the first frequency according to the user's first start instruction, but can also control the vibration component to stop vibrating according to the user's first stop instruction, allowing the user to actively terminate the first operating mode. The signal transmission between the various modules during the termination of the first operating mode is shown in Figure 13.

[0103] Among them, the first stop instruction can be sent by the user to the control module of the seat through at least one of the display screen, voice system, and switch mentioned above. The control module converts the first stop instruction into an electrical signal and sends it to the vibration component to control the vibration component to stop vibrating.

[0104] It should be noted that the user can also set the first vibration frequency of the seat in the first working mode according to specific massage needs. Specifically, it can be set through at least one of the display screen, voice system, and switch mentioned above, and transmitted to the control module of the seat.

[0105] Therefore, when the seat is in the first working mode, the user can independently control the vibration component to start vibration, stop vibration, vibration time and vibration frequency to meet the needs of different users and meet the needs of users in different usage scenarios.

[0106] In a specific embodiment, the seat vibration control method may further include the following steps:

[0107] After receiving the second start instruction from the user, controlling the vibration component to vibrate with the music;

[0108] After receiving the second stop instruction from the user, the vibration component is controlled to stop vibrating.

[0109] Typically, a vehicle is also equipped with a stereo system that can play music for the user's entertainment and relaxation. The controller of the stereo system is signal-connected to the control module of the seat.

[0110] The chair also has a second operating mode. When the chair's control module receives a second start command from the user, it can control the vibration component to vibrate in sync with the music played by the speakers. This means the vibration component can massage the user in sync with the music, relieving fatigue and enhancing the entertainment experience. The chair's vibration control module can control the vibration component to have a frequency that is the same as or close to the music played by the speakers, further enhancing the entertainment experience.

[0111] In one specific embodiment, the vehicle's display screen can also be used to play games. When the seat is in the second operating mode and the seat's control module receives a second start command from the user, it can control the vibration component to vibrate in time with the game's rhythm. This means the vibration component can massage the user as the game progresses, relieving fatigue and enhancing the entertainment experience. The seat's vibration control module can control the vibration frequency of the vibration component to be the same as, or close to, the game's rhythm, further enhancing the entertainment experience.

[0112] Specifically, please refer to Figure 14, which is a schematic diagram of the signal transmission in each module of the seat provided by this application when the seat is in the second working mode. The second start instruction can be sent by the user to the control module of the seat through at least one of the display screen, voice system, and switch mentioned above. The control module converts the second start instruction into an electrical signal and sends it to the vibration component to control the vibration of the vibration component. The second stop instruction can be sent by the user to the control module of the seat through at least one of the display screen, voice system, and switch mentioned above. The control module converts the second stop instruction into an electrical signal and sends it to the vibration component to control the vibration of the vibration component to stop vibrating. Therefore, the second working mode can also be actively started and stopped by the user.

[0113] In a specific embodiment, the vibration control method of the seat may further include the following steps:

[0114] When it is detected that the vehicle is in a dangerous state, the vibration component is controlled to vibrate at a second frequency; wherein the first frequency is lower than the second frequency.

[0115] In this embodiment, the vehicle can also be equipped with an Autonomous Driving Solution (hereinafter referred to as ADS), which is connected to the control module signal of the seat. When the vehicle is in automatic driving mode under the control of the ADS system, if the ADS system detects that the vehicle is in a dangerous working condition (for example, the vehicle is driving on a bumpy road, the vehicle is driving on a congested road, etc.), the driver needs to be reminded to take over driving. The control module of the seat can receive the control instruction of the ADS system, and convert the control instruction into an electrical signal and send it to the vibration component to control the vibration component to start vibrating and control the vibration component to vibrate at a second frequency. At this time, the seat is in the third working mode. Figure 15 is a schematic diagram of the signal transmission in each module when the seat provided in this application is in the third working mode. The direction of the arrow shown in Figure 15 is the direction of signal transmission.

[0116] The second frequency of the seat's vibration in the third operating mode is greater than the first frequency of the seat's vibration in the first operating mode. This means that when the ADS system detects a dangerous vehicle condition, the vibration component's vibration frequency is higher, quickly alerting the driver to take over and improving vehicle safety.

[0117] In a specific embodiment, after the vibration component vibrates at the second frequency, the vibration control method of the seat further includes the following steps:

[0118] After receiving the third stop instruction from the user, the vibration component is controlled to stop vibrating.

[0119] In this embodiment, when the seat is in the third operating mode, the seat's control module receives a start command from the ADS system and controls the vibration component to vibrate at the second frequency, thereby waking the driver. When the driver takes over driving, they can send a third stop command to the seat's control module. Upon receiving the user's third stop command, the seat's control module controls the vibration component to stop vibrating. This means that the seat's control module can not only control the vibration component to vibrate at the second frequency in response to the ADS system's start command, but can also control the vibration component to stop vibrating in response to the user's third end command, allowing the user to actively terminate the third operating mode. The signal transmission between the various modules during the process of starting and stopping the third operating mode is shown in Figure 15.

[0120] Among them, the third stop instruction can be sent by the user to the control module of the seat through at least one of the display screen, voice system, and switch mentioned above. The control module converts the third stop instruction into an electrical signal and sends it to the vibration component to control the vibration component to stop vibrating.

[0121] In another specific embodiment, when the vehicle is detected to be in a dangerous state, the vibration component is controlled to vibrate at the second frequency for a second preset time and then stop vibrating. That is, the seat control module can not only control the vibration component to vibrate at the second frequency according to the start instruction of the ADS system, but also control the vibration time of the vibration component so that the vibration component stops vibrating after the second preset time, thereby terminating the third operating mode.

[0122] For example, the second preset time may be set to 1 minute, that is, when it is detected that the vehicle is in a dangerous state, the vibration component is controlled to vibrate at the second frequency for 1 minute and then stop.
