Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to a control method and storage medium for a seat, an automobile, and an armrest assembly. Background Art

[0002] With the development of technology, cars have become a common means of transportation for people, and car seats are an important component that affects the comfort of car passengers.

[0003] In order to improve the user experience, armrests are usually added to seats so that passengers can put their arms on the armrests when sitting, thereby improving the comfort of passengers. However, as people's requirements for comfort gradually increase, the functions of seats have become more and more diverse. In addition to normal sitting, seats can also be adjusted to lying positions. However, when the state of the seat changes, the comfort of the armrests decreases and cannot meet the user's comfort requirements. Summary of the invention

[0004] The present application provides a control method and storage medium for a seat, a car, and an armrest assembly, which are used to improve the comfort of the seat.

[0005] The present application provides a seat, comprising:

[0006] A seat body, wherein the seat body is provided with at least one detection component, and the detection component is used to detect the angle of the current position of the seat body;

[0007] At least one armrest assembly, the armrest assembly comprising a body portion, a transmission assembly and a driving member, the body portion is mounted on the seat body, and the driving member is connected to the body portion through the transmission assembly;

[0008] A controller is used to receive the rotation angle detected by the detection component, and control the action of the driving member according to the rotation angle to drive the main body to rotate until the main body is in a horizontal state.

[0009] The embodiment of the present application can automatically detect and adjust the position of the main body when adjusting the seat body, so that the armrest assembly remains in a horizontal state. Even when the user adjusts the state of the seat body, the armrest assembly can still provide good support for the user's arms to improve the user's comfort.

[0010] In a possible implementation, the seat body includes a backrest and a seat pot, the backrest and the seat pot are connected and can rotate relatively, and the body portion is mounted on the backrest;

[0011] The detection component comprises a first Hall element, which is arranged on the backrest and is used to detect the rotation angle of the backrest, and / or;

[0012] The detection component includes a second Hall element, which is arranged on the seat bowl and is used to detect the rotation angle of the seat bowl;

[0013] The controller is used to control the action of the driving member according to the rotation angle of the backrest and / or the rotation angle of the seat basin, so as to drive the main body to rotate until the main body is in a horizontal state.

[0014] Through such a design, when the user adjusts the seat body, the seat basin and the backrest can be adjusted by the body. By changing the angles of the seat basin and the backrest, the seat body can be placed in different states. For example, the seat body can be in different states such as sitting, semi-reclining, lying, and zero-gravity lying. At the same time, users of different body shapes and different riding habits can adjust the seat body to a state suitable for themselves according to their own needs. When the user adjusts the seat body, the seat body may be in a non-preset state. The preset state may include the initial state of the seat and the zero-gravity lying state. The other states such as the semi-reclining state and the sitting state adjusted by the user are non-preset states. Since different users have different posture requirements for the seat body, the embodiment of the present application installs the body part on the backrest so that when the user adjusts the seat body, the body part can move with the backrest, and the driving member drives the body part to maintain a horizontal state to meet the user's use requirements for the armrests, thereby improving the comfort and use experience of the seat.

[0015] In a possible implementation manner, the seat has a cup holder, and the cup holder is mounted on the main body.

[0016] The cup holder can be provided to facilitate users to place items such as water cups. Compared with the arrangement of the cup holder and the armrest separately, such as placing the cup holder on the dashboard, console, etc. of the car, integrating the cup holder with the armrest assembly can be more convenient for placing or taking items in the cup holder. When the user adjusts the posture of the seat body, the cup holder will adjust accordingly with the main body, so that the user can place or take items in the cup holder in different postures. Moreover, the solution provided in the embodiment of the present application can drive the main body to maintain a horizontal state through a driving member. Therefore, when the user adjusts the posture of the seat body, the cup holder provided on the main body can also maintain a horizontal state, thereby reducing the possibility of items in the cup holder falling or liquid spilling, thereby reducing the possibility of accidents such as scalding users or causing electrical risks due to liquid spilling, thereby helping to improve safety and better meet actual usage needs.

[0017] In a possible implementation manner, the main body has a receiving cavity, the cup holder can move along the receiving cavity, and at least a portion of the cup holder can extend or retract relative to the receiving cavity.

[0018] This design makes it easy to adjust the relative positions of the cup holder and the main body. The cup holder can be extended when needed and retracted when not needed, thereby reducing the space occupied by the cup holder and better meeting actual usage needs.

[0019] In a possible implementation manner, the driving component is a Hall drive motor.

[0020] The Hall drive motor can drive the main body to rotate and detect the rotation angle of the main body at the same time.

[0021] In a possible implementation manner, the seat includes two armrest assemblies, and along the width direction of the seat, the armrest assemblies are located at two opposite side armrest assemblies of the seat body.

[0022] By providing armrest assemblies on both sides of the seat body, it can help improve the user's riding experience and better meet actual usage needs.

[0023] In a possible implementation, the transmission assembly includes a reducer, a gear, and a recliner, the driving member is connected to the reducer, the recliner is mounted on the main body, and the reducer is connected to the recliner via a gear.

[0024] Such a design makes it easy for the driving member to be connected to the main body and drive the main body to rotate.

[0025] The present application also provides a car, comprising:

[0026] Car body;

[0027] A seat, wherein the seat is mounted on the vehicle body;

[0028] Wherein, the seat is the seat described in any one of the above items.

[0029] The present application also provides a control method for an armrest assembly, wherein the armrest assembly is mounted on a seat body, and the control method comprises:

[0030] Detecting the angle of the current position of the seat body;

[0031] The armrest assembly is controlled to rotate to a horizontal state according to the angle of the current position.

[0032] This design can control the armrest assembly of the seat to be adjusted to a horizontal state for the convenience of users. When the user adjusts the angle of the seat body, the armrest assembly can be adjusted by detecting the angle of the current position of the seat body to make the armrest assembly in a horizontal state, which is beneficial to improving user comfort.

[0033] In a possible implementation manner, the seat body includes a backrest and a seat basin, the armrest assembly is mounted on the backrest, and when detecting the rotation angle of the seat body, the control method includes:

[0034] The angle of the current position of the backrest is detected.

[0035] The armrest assembly is installed on the backrest, so when the user adjusts the backrest, the armrest assembly will move with the movement of the backrest. Therefore, the user's comfort can be improved by detecting the angle of the current position of the backrest and adjusting the armrest assembly according to the angle of the current position of the backrest to make the armrest assembly in a horizontal state.

[0036] In a possible implementation manner, before detecting the angle of the current position of the seat body, the control method further includes:

[0037] Receiving a preset state of the seat body set by a user;

[0038] According to the preset state, the backrest of the seat body is controlled to rotate to a preset angle corresponding to the preset state, and the armrest assembly is controlled to maintain horizontality during the rotation of the seat body.

[0039] The user can preset the posture of the seat body through the operation screen set on the seat body or the armrest assembly to meet the user's usage needs. At the same time, when the seat body is adjusted to the preset state, the armrest assembly is controlled to rotate relative to the seat body so that the armrest assembly is always in a horizontal state.

[0040] In a possible implementation manner, the preset state includes a lying position or a sitting position and any state therebetween.

[0041] The preset state can be a posture commonly used by the user, including but not limited to a sitting position, a lying position, and any posture in between. The posture of the seat body can also be preset by limiting the angle of the backrest.

[0042] In a possible implementation manner, when it is detected that the angle of the current position of the seat body is a first preset angle α, the armrest assembly is controlled to rotate to a second preset angle β.

[0043] In a possible implementation manner, the control method further includes:

[0044] After the car is powered off, at least one of the armrest components is controlled to rotate to a preset angle with the seat body.

[0045] The present application also provides a storage medium, which is used in the control method of the armrest assembly described in any one of the above items.

[0059] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0060] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

The singular forms "a", "said" 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 other meanings.

[0062] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0063] With the development of technology, cars have become a common means of transportation for people. Car seats are one of the important factors affecting the riding comfort of passengers. In order to improve the riding experience of passengers, armrests can be set on one or both sides of the seat. When riding, passengers can put their arms on the armrests to get a more comfortable experience. As people's life and work scenes in the car become more and more frequent, the functions of seats are becoming more and more abundant. In addition to the conventional sitting state, the seat back and seat basin can be adjusted to achieve zero-gravity lying state. However, when the state of the seat changes, the position of the armrest designed for the sitting position cannot adapt to the needs of the lying state, etc. When the seat is in the lying state, the armrest cannot meet the use needs of the passengers, affecting the comfort of the seat.

[0064] In view of this, the embodiments of the present application provide a control method and storage medium for a seat, a car, and an armrest assembly, which are used to improve the comfort of the seat and meet the user's usage needs.

[0065] like Figure 1 As shown, an embodiment of the present application provides a seat, which can be used in vehicles such as cars. The seat includes a seat body 1 and at least one armrest assembly 2, and the armrest assembly 2 is installed on the seat body 1.

[0066] like Figure 2As shown, the armrest assembly 2 includes a body 21, a transmission assembly 22 and a driving member 23, wherein the body 21 may be made of a metal frame, and the driving member 23 may be a Hall drive motor, or other driving devices capable of detecting a rotation angle, such as a stepping motor. The driving member 23 is connected to the body 21 through the transmission assembly 22 to drive the body 21 to rotate relative to the seat body 1. The transmission assembly 22 may include a gear 222, a reducer 221 and a recliner 223, the output end of the driving member 23 is connected to the reducer 221, and the reducer 221 is connected to the recliner 223 installed on the body 21 through the gear 222. The reducer 221 plays a role of deceleration, and the gear 222 is used to transmit the driving force to the recliner 223, and the recliner 223 can adjust the angle of the body 21, thereby changing the relative position of the body 21 and the seat body 1.

[0067] At least one detection component is disposed on the seat body 1 , and the detection component may be a Hall element, which is used to detect the movement of the seat body 1 .

[0068] like Figure 3 As shown, the body 21 may include a frame 211, and the transmission assembly 22 is connected to the body 21 through the frame 211. The body 21 may also include plastic parts and covering parts arranged outside the frame 211 to improve the comfort of the user when using the armrest assembly 2. The seat also includes a controller, which may be installed on the seat body 1 or may be arranged at other locations such as a console of a car, which is not limited here.

[0069] At least one detection component is disposed on the seat body 1 , and the detection component may be a Hall element, which is used to detect the movement of the seat body 1 and send detection information to the controller. The detection information is used to reflect the rotation angle of the seat body 1 .

[0070] The controller is used to receive the detection information sent by the detection component, and according to the detection information, send a control signal to the driving member 23, so that the driving member 23 drives the rotation angle of the main body 21 relative to the seat body 1, that is, the controller can control the action of the driving member 23 through the rotation angle detected by the detection component to drive the main body 21 to rotate until the main body 21 is in a horizontal state.

[0071] Specifically, the driving member 23 may include a Hall sensor and a driving device, and the driving device is used to drive the body portion 21 to move relative to the seat body 1. The Hall sensor is used to detect the relative position of the body portion 21 and the seat body 1. The driving device can adjust the relative position of the body portion 21 and the seat body 1 according to the signal of the controller so that the body portion 21 is in a horizontal state.

[0072] The driving member 23 may be a Hall drive motor.

[0073] The Hall drive motor detects the position of the main body 21 using the Hall effect and drives the main body 21 to move relative to the seat body 1. Figure 4 As shown in the figure, the Hall effect is caused by the interaction between the corresponding electric field and magnetic field of charged particles (such as electrons). When electrons move in a magnetic field, they are affected by the Lorentz force. When electrons (negative charges) move upward, the current (positive charges) they generate moves downward. According to the left-hand rule, the electrons move to the right, and the charges in the thin plate will tilt to one side, then a potential difference will be formed on the left and right sides, namely the Hall voltage. This is the basic principle of the Hall signal generation. The working principle of the Hall drive motor is as follows: Figure 5 As shown in the figure, the Hall drive motor uses the magnetic ring and Hall sensor implanted inside the brushed DC motor to collect the Hall signal generated on the motor rotor. The motor can include components such as the rotor, armature winding, positive brush, commutator and shaft. The motor integrates the Hall sensor, and generates a set of Hall signals for each rotation of the motor. Figure 6 The square wave signal shown in the figure analyzes the frequency and quantity of the Hall signal to realize the control of the unknown angle position. That is, the Hall drive motor can be used to detect the rotation angle and position of the main body 21 while driving the main body 21 to move.

[0074] The embodiment of the present application can automatically detect and adjust the position of the main body 21 when adjusting the seat body 1, so that the armrest assembly 2 remains in a horizontal state, even if the user moves the seat body from Figure 1 The status shown is adjusted to Figure 7 In the state shown, the armrest assembly 2 can still provide good support for the user's arms to improve the user's comfort.

[0075] in, Figure 1 The seat state shown can be a regular sitting state. Figure 7 The seat position shown may be a zero gravity position.

[0076] Compared with the solution in which the armrest is installed on the chassis of a car, a console, etc. and the armrest is separately arranged from the seat body 1, when the user adjusts the state of the seat body 1, since the armrest and the seat body 1 are relatively independently arranged, when the state of the seat body 1 changes, the position of the armrest remains unchanged. However, when the user is in different states, the requirements for the position of the armrest are different. For example, when the user adjusts the seat body 1 from a sitting position to a lying position, the relative position between the armrest and the seat body 1 changes, resulting in the armrest position suitable for the sitting position not being suitable for the lying position. The solution provided in the embodiment of the present application installs the armrest assembly 2 on the seat body 1. Therefore, when it is used to adjust the state of the seat body 1, the position of the armrest assembly 2 can change with the seat body 1. At the same time, the position of the main body 21 is detected by the driving member 23, so that when the seat body 1 is in different postures, the main body 21 can be in a horizontal state, so that the user can put his arm on the main body 21 to improve the riding experience and comfort.

[0077] It should be noted here that the horizontal state mentioned in the embodiments of the present application is not horizontal in an absolute sense, but an approximately horizontal state.

[0078] Such a design can make the main body 21 suitable for the seat body 1 in different states, and the user can put his arms on the armrest assembly 2 more comfortably when sitting in different postures, thereby improving the user's riding experience.

[0079] like Figure 7 As shown, in a possible embodiment, the chair body 1 includes a seat 12 and a backrest 11, and the backrest 11 is connected to the seat 12. The user can sit on the seat 12 and lean on the backrest 11. The backrest 11 and the seat 12 can move relative to each other, and the angle of the seat 12 can also be adjusted. The body 21 can be installed on the backrest 11.

[0080] The detection component includes at least a first Hall element and / or a second Hall element, the first Hall element is used to detect the rotation angle of the backrest 11, and the second Hall element is used to detect the rotation angle of the seat basin 12. The first Hall element and the second Hall element can send the detection results to the controller, and the controller analyzes and processes the detection results of the first Hall element and / or the second Hall element to calculate the angle that the main body 21 of the armrest assembly 2 needs to rotate to maintain a horizontal state, and sends a signal to the driving member 23. The driving member 23 controls the main body 21 to rotate relative to the backrest 11 according to the signal to keep the main body 21 in a horizontal state.

[0081] Through such a design, when the user adjusts the seat body 1, the seat basin 12 and the backrest 11 can be adjusted. By changing the angles of the seat basin 12 and the backrest 11, the seat body 1 can be in different states. For example, the seat body 1 can be in different states such as sitting, semi-reclining, lying, and zero-gravity lying. At the same time, users of different body shapes and different sitting habits can adjust the seat body 1 to a state suitable for themselves according to their own needs. When the user adjusts the seat body 1, the seat body 1 may be in a non-preset state. The preset state may include the initial state of the seat and the "zero-gravity" lying state. The remaining states such as the semi-reclining state and the sitting state adjusted by the user are non-preset states. Since different users have different posture requirements for the seat body 1, the embodiment of the present application installs the body part 21 on the backrest 11 so that when the user adjusts the seat body 1, the body part 21 can move with the backrest 11, and the driving member 23 is used to drive the body part 21 to maintain a horizontal state, so as to meet the user's use requirements for the armrest, thereby improving the comfort and use experience of the seat.

[0082] like Figure 7 As shown, in a possible implementation manner, the seat provided in the present application may further include a cup holder 3 , and the cup holder 3 is mounted on the main body 21 .

[0083] The cup holder 3 can be provided to facilitate the user to place items such as water cups. Compared with the arrangement of the cup holder 3 and the armrest separately, such as placing the cup holder 3 on the dashboard, console, etc. of the car, the integration of the cup holder 3 with the armrest assembly 2 can be more convenient for placing or taking items in the cup holder 3. When the user adjusts the posture of the seat body 1, the cup holder 3 will be adjusted accordingly with the main body 21, so that the user can place or take items in the cup holder 3 in different postures. Moreover, the solution provided in the embodiment of the present application can drive the main body 21 to maintain a horizontal state through the driving member 23. Therefore, when the user adjusts the posture of the seat body 1, the cup holder 3 provided on the main body 21 can also maintain a horizontal state, thereby reducing the possibility of items in the cup holder 3 falling or liquid spilling, thereby reducing the possibility of accidents such as scalding users or causing electrical risks due to liquid spilling, thereby helping to improve safety and better meet actual usage needs.

[0084] In a possible implementation, the main body 21 has a receiving cavity, and the cup holder 3 can move along the receiving cavity, so that at least a portion of the cup holder 3 can extend or retract relative to the receiving cavity.

[0085] This design makes it easy to adjust the relative positions of the cup holder 3 and the main body 21. The cup holder 3 can be extended when needed and retracted when not needed, thereby reducing the space occupied by the cup holder 3 and better meeting actual usage needs.

[0086] like Figure 7 As shown, in a possible embodiment, the seat includes two armrest assemblies 2, and along the width direction of the seat, the armrest assemblies 2 are respectively located on opposite sides of the seat body 1,

[0087] By providing armrest assemblies on both sides of the seat body 1, it is helpful to improve the user's riding experience and better meet actual usage needs.

[0088] like Figure 8 As shown, the seat provided by the embodiment of the present application can output the Hall signals of the backrest 11 and the seat basin 12 to the controller in real time through the first Hall element and the second Hall element when in use. The controller analyzes the angular positions of the backrest 11 and the seat basin 12 in real time according to the received Hall signals, and selects the angle that the armrest needs to rotate to be in a horizontal state, and outputs a corresponding signal to the drive member 23. After receiving the signal from the controller, the drive member 23 drives the main body 21 to rotate relative to the seat body 1 so that the main body 21 is in a horizontal state. At the same time, the Hall drive device feeds back the position signal of the main body 21 to the controller so that the controller can monitor and adjust the position of the main body 21 in real time. The controller can record the position status of the seat body 1 and the armrest assembly 2.

[0089] Based on the seats involved in the above embodiments, the embodiments of the present application also provide a car, which includes a body and a seat, and the seat is installed on the body, wherein the seat can be the seat involved in any of the above embodiments. Since the seat has the above technical effects, the car including the seat also has the above technical effects, which will not be repeated here.

[0090] The embodiment of the present application also provides a control method for an armrest assembly 2, which can be used for the seat mentioned above.

[0091] The armrest assembly 2 is mounted on the seat body 1, and the control method includes:

[0092] Detecting the angle of the current position of the seat body 1;

[0093] The armrest assembly 2 is controlled to rotate to a horizontal state according to the angle of the current position.

[0094] Through such a design, the armrest assembly 2 of the seat can be controlled to be adjusted to a horizontal state for the convenience of users. When the user adjusts the angle of the seat body 1, the armrest assembly 2 can be adjusted by detecting the angle of the current position of the seat body 1 to make the armrest assembly 2 in a horizontal state, which is beneficial to improving the user's comfort.

[0095] The seat body 1 includes a backrest 11 and a seat basin 12, and the armrest assembly 2 is installed on the backrest 11. When detecting the rotation angle of the seat body 1, the control method includes:

[0096] The angle of the current position of the backrest 11 is detected.

[0097] The armrest assembly 2 is installed on the backrest 11. Therefore, when the user adjusts the backrest 11, the armrest assembly 2 will move with the movement of the backrest 11. Therefore, the user's comfort can be improved by detecting the angle of the current position of the backrest 11 and adjusting the armrest assembly 2 according to the angle of the current position of the backrest 11 to make the armrest assembly 2 in a horizontal state.

[0098] In a possible embodiment, the seat may be provided with a first Hall element and a second Hall element, wherein the first Hall element is used to detect the adjustment angle of the backrest 11, and the second Hall element is used to detect the adjustment angle of the seat basin 12. When the user adjusts the backrest 11 alone, the armrest assembly 2 moves with the movement of the backrest 11, and when the user adjusts the seat basin 12, the backrest 11 moves with the movement of the seat basin 12. Therefore, providing two Hall elements can more accurately detect the current position angle of the backrest 11, and the controller can calculate the current position angle of the backrest 11 based on the detection results of the first Hall element and the second Hall element, and control the driving member 23 to adjust the main body 21 based on the position angle.

[0099] Before detecting the angle of the current position of the seat body 1, the control method further includes:

[0100] Receiving a preset state of the seat body 1 set by a user;

[0101] According to the preset state, the backrest 11 of the seat body 1 is controlled to rotate to a preset angle corresponding to the preset state, and the armrest assembly 2 is controlled to maintain horizontality during the rotation of the seat body 1.

[0102] The user can preset the posture of the seat body 1 through the operation screen set on the seat body 1 or the armrest assembly 2 to meet the user's usage needs. At the same time, when the seat body 1 is adjusted to the preset state, the armrest assembly 2 is controlled to rotate relative to the seat body 1 so that the armrest assembly 2 is always in a horizontal state.

[0103] By presetting the posture of the seat body 1, it can be automatically adjusted to a corresponding state directly after the user's selection, which is more convenient to use.

[0104] In a possible implementation manner, the preset state includes a lying position or a sitting position and any state therebetween.

[0105] The preset state may be a posture commonly used by the user, including but not limited to a sitting posture, a lying posture, and any posture in between. The posture of the seat body 1 may also be preset by limiting the angle of the backrest 11 .

[0106] When in use, the user can directly select a preset posture, and the controller automatically adjusts the seat body 1 according to the selected posture, and during the adjustment process, keeps the armrest assembly 2 horizontal.

[0107] In a possible implementation manner, when it is detected that the angle of the current position of the seat body 1 is a first preset angle α, the armrest assembly 2 is controlled to rotate to a second preset angle β.

[0108] The controller can adjust the angle of the armrest assembly 2 according to the angle of the seat body 1 .

[0109] Generally, when the armrest assembly 2 is already in a horizontal state, when the user adjusts the posture of the seat body 1, α and β can satisfy α=-β. When the armrest assembly 2 is not in a horizontal state, the controller can calculate the angle that the armrest assembly 2 needs to rotate from the current state to the horizontal state, and calculate β in combination with the current position angle α of the seat body 1.

[0110] In a possible implementation manner, the control method further includes:

[0111] After the car is powered off, at least one of the armrest components 2 is controlled to rotate to a preset angle with the seat body 1 .

[0112] The control method may include a welcoming mode, when the car is powered off, the controller may control at least one armrest assembly 2 to rotate to a preset angle between the seat body 1, usually the armrest assembly 2 near the door side rotates to the body portion 21 and the backrest 11 parallel, so that the user can get off the car. When the user gets on the car, it can be determined whether the user is sitting in the seat by whether the user has inserted the seat belt.

[0113] When the user gets off the vehicle, whether the power is off is usually used as the basis for judgment. When whether the user unplugs the seat belt is used as the basis for ending the control, the seat belt is easily bumped against the user because the plug-in and unplugging positions of the seat belt are usually close to the armrest.

[0114] like Fig. 9As shown, in a possible implementation, when the user sits on the seat and starts to control the seat, the main body 21 can be adjusted to a horizontal state to facilitate the user to sit. When the user can select a usage scenario to control the seat, when the user selects a preset usage scenario, the controller controls the seat body 1 to automatically adjust to a preset posture, and during the adjustment process, controls the armrest assembly 2 to remain horizontal. When armrest assemblies 2 are provided on both sides of the seat, the armrest assemblies 2 on both sides are controlled to adjust to a specified position, that is, both armrest assemblies 2 are in a horizontal state, so that the support positions of the two armrest assemblies 2 are consistent. When the user does not select a preset usage scenario and chooses to adjust the state of the seat body 1 by himself, the controller obtains the angle of the current position of the seat body 1 in real time according to the first Hall element and the second Hall element, and controls the driving member 23 to drive the main body 21 to rotate, so as to adjust the state of the armrest assembly 2 in real time, so that the armrest assembly 2 remains in a horizontal state. When the car is powered off, the control ends.

[0115] In actual use, since the armrest assembly 2 rotates and folds up after the user gets off the vehicle, the user does not need to adjust the armrest assembly 2 to a horizontal state when riding next time, and waits for the user to select a usage scenario. After the user selects a usage scenario, the armrest assembly 2 is adjusted to a horizontal state during the process of adjusting to the corresponding usage scenario.

[0116] like Fig.10 As shown, the armrest on one side of the seat is in the storage position to facilitate users to get on and off the vehicle.

[0117] An embodiment of the present application also provides a storage medium, which is used to store the control method of the armrest assembly involved in any of the above items.

[0118] The embodiment of the present application provides a control method and storage medium for a seat, a car, and an armrest assembly, wherein the seat includes a seat body 1 and at least one armrest assembly 2, the armrest assembly 2 includes a body portion 21, a transmission assembly 22, and a drive member 23, the body portion 21 is mounted on the seat body 1, and the drive member 23 is connected to the body portion 21 through the transmission assembly 22. The control is used to receive the rotation angle detected by the detection component of the seat body 1, and the drive member 23 is controlled according to the rotation angle to drive the body portion 21 to maintain a horizontal state. Through such a design, the body portion 21 can automatically maintain a horizontal state, which is convenient for users to use and improves the riding experience.

[0119] The car seat armrest structure with a cup holder and having an angle adaptive function in the present invention can solve the following problems:

[0120] In zero-gravity or reclining posture, it is inconvenient to take and put the cup holder due to human posture restrictions; in the reclining position, the armrest angle is not horizontal, affecting the comfort. It can also solve the problem that the cup holder rotates with the armrest when the armrest angle is adjusted, and water in the cup can easily cause the water to spill and overturn, scalding passengers, and causing electrical risks. In response to the pain points of existing seat armrests and cup holders, a car seat armrest structure with cup holder with angle adaptive function is invented, which improves the comfort of armrest use and the convenience and safety of cup holder use.

[0121] The retractable cup holder and electric movable armrest are arranged on the comfort seat, and a specific control logic is adopted. The armrest can always maintain a horizontal comfortable angle according to the seat posture, which is suitable for the in-car environment and obtains good riding comfort. The seat armrest can be inherited from the seat body, saving space and obtaining a good space experience; it is suitable for zero-gravity seat posture situations and the use scenarios where the user normally adjusts the backrest and seat cushion angle, and the use scenarios of getting on and off the car, and can achieve real-time maintenance of the armrest horizontal comfortable angle according to the seat posture, improve riding comfort and convenience of use, and avoid the electrical risk caused by water spilling and overturning when the cup holder rotates with the armrest, and the safety risk of scalding passengers.

[0122] Electric armrest horizontal adaptive structure (Hall motor, controller, armrest structure, cup holder).

[0123] The vehicle seat armrest with a cup holder having an angle adaptive function uses control logic, including different control logic in a zero-gravity posture and a non-zero-gravity posture.

[0124] Control logic of the boarding welcome mode: the armrests are retracted after the power is turned off when getting off the vehicle. After the user puts on the seat belt after getting on the vehicle, the armrests are automatically lowered to the horizontal position.

[0125] Seat with dual electric armrests, horizontally adaptive structure

[0126] The double armrest seat consists of an outer electric armrest and an inner electric movable adaptive armrest. The electric adaptive armrest body consists of the armrest body, armrest frame bracket, armrest external plastic parts and covering parts, hidden cup holder and other functional parts.

[0127] Control logic for using the car seat armrest with cup holder and angle adaptive function

[0128] The principle of achieving horizontal adaptation is:

[0129] (1) The backrest motor angle and seat cushion rotation angle are obtained in real time through the Hall motor.

[0130] (2) The controller collects the backrest and seat angle information in real time, and uses a logic algorithm to calculate the angle that the armrest needs to rotate to the horizontal position. It sends a signal to the armrest motor to drive the armrest Hall motor to rotate to a specific position (horizontal position or nearby position).

[0131] Adaptive movable armrest structure

[0132] The electric armrest consists of an armrest rotating structure, a Hall motor and its transmission structure (reducer, transmission gear, angle adjuster), a control unit (whole chair controller), etc. The electric adaptive armrest body consists of the armrest body, armrest frame bracket, armrest external plastic parts and covering parts, pop-up cup holder and other functional parts.

[0133] The solution provided in the embodiment of the present application adopts the Hall principle to identify the position of the seat, and uses the Hall motor to identify the angle position of the seat cushion, the backrest, and the armrest. The Hall motor is used to determine whether the armrest has reached a predetermined angle and position.

[0134] The car seat armrest with cup holder with angle adaptive function uses control logic. With specific control logic, it is suitable for the in-car environment. The position and posture of the armrest are automatically and dynamically adjusted during the adjustment process. The angle is always kept horizontal, and the water in the cup holder does not spill out. It is suitable for the scene of achieving zero gravity posture, and also for the scene of users adjusting the seat back and cushion during normal sitting.

[0135] The adaptive movable armrest structure, the electric armrest is composed of the armrest rotating structure, the Hall motor and its transmission structure (reducer, transmission gear, angle adjuster), the control unit (whole chair controller), etc. Under the control of the motor and controller, this mechanical structure can perform the effect of the armrest adaptive level.

[0136] The control logic of the welcome mode is that the armrest will be retracted after the power is turned off when getting off the car. After the user puts on the seat belt after getting on the car, the armrest will automatically drop to the horizontal position. It is convenient for users to plug and unplug the seat belt and improve the riding experience.
