Description

A control method and storage medium for a seat, a car, and an armrest assembly

[0001] This invention claims priority to the Chinese patent application filed with the State Intellectual Property Office on December 4, 2023, with application number 202311661226.1 and application name “A control method and storage medium for a seat, automobile, and armrest assembly,” the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention 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

[0003] 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.

[0004] To enhance the user experience, armrests are often added to seats, allowing passengers to rest their arms while sitting, improving comfort. However, as people's demand for comfort gradually increases, seats have become increasingly versatile, with adjustments to positions other than normal seating, such as reclining. However, when the seat changes position, the comfort of the armrests decreases, failing to meet the user's comfort needs. Summary of the Invention

[0005] Embodiments of the present application provide a control method and storage medium for a seat, a car, and an armrest assembly, for improving seat comfort.

[0006] An embodiment of the present application provides a seat, comprising:

[0007] A seat body, wherein the seat body is provided with at least one detection component, the detection component is used to detect the angle of the current position of the seat body;

[0008] at least one armrest assembly, the armrest assembly comprising a body portion, a transmission assembly, and a drive member, the body portion being mounted on the seat body, and the drive member being connected to the body portion via the transmission assembly;

[0009] A controller is configured to receive the rotation angle detected by the detection component and control the driving member to move according to the rotation angle to drive the main body to rotate until the main body is in a horizontal state.

[0010] 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.

[0011] In a possible embodiment, the seat body includes a backrest and a seat basin, the backrest and the seat basin are connected and can rotate relative to each other, and the main body is mounted on the backrest;

[0012] The detection component includes a first Hall element, which is arranged on the backrest and is used to detect the rotation angle of the backrest, and / or;

[0013] The detection component includes a second Hall element, which is provided on the bidet and is used to detect the rotation angle of the bidet;

[0014] 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.

[0015] With this design, when the user adjusts the seat body, the seat basin and backrest can be adjusted by the seat body. By changing the angle of the seat basin and 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 with different body shapes and different riding habits can adjust the seat body to a state that suits them 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. 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 requirements for the posture of the seat body, the embodiment of the present application installs the main body part on the backrest so that when the user adjusts the seat body, the main body part can move with the backrest, and uses the driving member to drive the main body part to maintain a horizontal state to meet the user's use requirements for the armrests, thereby improving the comfort and user experience of the seat.

[0016] In a possible implementation manner, the seat has a cup holder, and the cup holder is mounted on the main body.

[0017] By providing a cup holder, it is convenient for users to place items such as water cups. Compared with providing the cup holder separately from the armrest, 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 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 body to maintain a horizontal state through the driving member. Therefore, when the user adjusts the posture of the seat body, the cup holder provided on the 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 the user or causing electrical risks due to liquid spilling, thereby helping to improve safety and better meet actual usage needs.

[0018] In a possible implementation, the main body has a receiving cavity, the cup holder is movable along the receiving cavity, and at least a portion of the cup holder is extendable or retractable relative to the receiving cavity.

[0019] This design makes it easy to adjust the relative position 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.

[0020] In a possible implementation, the driving component is a Hall drive motor.

[0021] The Hall drive motor can drive the main body to rotate while also detecting the rotation angle of the main body.

[0022] In a possible implementation, the seat includes two armrest assemblies, and along the width direction of the seat, the armrest assemblies are located on two opposite sides of the seat body.

[0023] 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.

[0024] In a possible implementation, the transmission assembly includes a reducer, gears, 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 gears.

[0025] This design facilitates the connection of the driving member with the main body and drives the main body to rotate.

[0026] The present application also provides a vehicle, comprising:

[0027] body;

[0028] a seat, the seat being mounted on the vehicle body;

[0029] Wherein, the seat is any one of the seats described above.

[0030] The present application also provides a method for controlling an armrest assembly, wherein the armrest assembly is mounted on a seat body, and the control method includes:

[0031] detecting the angle of the current position of the seat body;

[0032] The armrest assembly is controlled to rotate to a horizontal state according to the angle of the current position.

[0033] Through such a design, the armrest assembly 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, 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 conducive to improving user comfort.

[0034] In a possible implementation, 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:

[0035] The angle of the current position of the backrest is detected.

[0036] 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.

[0037] In a possible implementation manner, before detecting the angle of the current position of the seat body, the control method further includes:

[0038] receiving a preset state of the seat body set by a user;

[0039] 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 a horizontal level during the rotation of the seat body.

[0040] The user can preset the seat's posture through an operation screen located on the seat or armrest assembly to meet their needs. Simultaneously, when the seat is adjusted to the preset position, the armrest assembly is controlled to rotate relative to the seat body to ensure that the armrest assembly is always horizontal.

[0041] In a possible implementation, the preset state includes a lying position or a sitting position and any state therebetween.

[0042] 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.

[0043] In a possible implementation, 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.

[0044] In a possible implementation, the control method further includes:

[0045] 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.

[0046] An embodiment of the present application further provides a storage medium, which is used in the control method of the armrest assembly described in any one of the above items.

[0047] Embodiments of the present application provide a control method and storage medium for a seat, automobile, and armrest assembly. The seat includes a seat body and at least one armrest assembly, wherein the armrest assembly includes a body portion, a transmission assembly, and a driver. The body portion is mounted on the seat body, and the driver is connected to the body portion via the transmission assembly. A control unit is used to receive a rotation angle detected by a detection component of the seat body, and controls the driver to drive the body portion to maintain a horizontal state based on the rotation angle. This design allows the body portion to automatically maintain a horizontal state, making it easier for users to use and improving the riding experience. BRIEF DESCRIPTION OF THE DRAWINGS

[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 embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0061] 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.

[0062] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[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 for a more comfortable experience. As people live and work in cars more and more frequently, the functions of seats are becoming more and more abundant. In addition to the conventional sitting position, the seat back and seat basin can be adjusted to achieve zero-gravity lying position and other states. However, when the state of the seat changes, the position of the armrest designed for sitting position cannot adapt to the needs of lying position and other states. When the seat is in lying position and other states, 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] As shown in FIG1 , an embodiment of the present application provides a seat that can be used in vehicles such as automobiles. The seat includes a seat body 1 and at least one armrest assembly 2 , which is mounted on the seat body 1 .

[0066] As shown in Figure 2, the armrest assembly 2 includes a main body 21, a transmission assembly 22, and a driver 23. The main body 21 can be made of a metal frame, and the driver 23 can be a Hall effect drive motor or other drive device capable of detecting rotation angles, such as a stepper motor. The driver 23 is connected to the main body 21 via the transmission assembly 22 to drive the main body 21 to rotate relative to the seat body 1. The transmission assembly 22 can include a gear 222, a reducer 221, and a recliner 223. The output end of the driver 23 is connected to the reducer 221, which is connected to the recliner 223 mounted on the main body 21 via the gear 222. The reducer 221 acts as a speed reducer, and the gear 222 is used to transmit the driving force to the recliner 223. The recliner 223 can adjust the angle of the main body 21, thereby changing the relative position of the main body 21 and the seat body 1.

[0067] At least one detection component is provided on the seat body 1 , and the detection component may be a Hall element, for detecting the movement of the seat body 1 .

[0068] As shown in Figure 3, the main body 21 may include a frame 211, through which the transmission assembly 22 is connected. The main body 21 may also include plastic components and coverings disposed outside the frame 211 to enhance user comfort when using the armrest assembly 2. The seat also includes a controller, which may be mounted on the seat body 1 or located elsewhere, such as in the vehicle's console, without limitation.

[0069] At least one detection component is provided 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 receives detection information from the detection component and, based on this information, sends a control signal to the driver 23, causing the driver 23 to adjust the rotation angle of the main body 21 relative to the seat body 1. Specifically, the controller controls the driver 23 based on the rotation angle detected by the detection component, thereby rotating the main body 21 until it is horizontal.

[0071] Specifically, the driving member 23 may include a Hall effect sensor and a driving device, the driving device being configured to drive the body portion 21 to move relative to the seat body 1. The Hall effect sensor is configured to detect the relative position of the body portion 21 and the seat body 1. The driving device is configured to adjust the relative position of the body portion 21 and the seat body 1 based on a signal from the controller to maintain the body portion 21 in a horizontal position.

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

[0073] The Hall effect motor uses the Hall effect to detect the position of the main body 21 and drive the main body 21 to move relative to the seat body 1. As shown in Figure 4, the Hall effect is caused by the interaction between the electric and magnetic fields of charged particles (such as electrons). When electrons move in a magnetic field, they are subject to the Lorentz force. When electrons (negative charges) move upward, the current they generate (positive charges) flows downward. According to the left-hand rule, the electron's hand moves to the right, causing the charges in the thin plate to tilt to one side. This creates a potential difference between the left and right sides, known as the Hall voltage, which is the basic principle of Hall signal generation. The operating principle of the Hall effect motor is shown in Figure 5. The Hall effect motor uses a magnetic ring and Hall sensor embedded in a brushed DC motor to collect Hall signals generated by the motor rotor. The motor can include components such as the rotor, armature winding, positive brushes, commutator, and shaft. The motor integrates a Hall effect sensor. Each rotation of the motor generates a set of square wave signals, as shown in Figure 6. The frequency and quantity of the Hall effect signals are analyzed to control the unknown angular 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 when the user adjusts the seat body from the state shown in Figure 1 to the state shown in Figure 7, the armrest assembly 2 can still provide better support for the user's arms to improve the user's comfort.

[0075] The seat state shown in FIG1 may be a conventional sitting state, and the seat state shown in FIG7 may be a zero-gravity state.

[0076] Compared with the solution of installing the armrest on the chassis of the car, the console, etc., where the armrest is separated 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 independent, 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 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 driving member 23 is used to detect the position of the main body 21, 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, thereby improving 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 is approximately horizontal.

[0078] This design allows the main body 21 to be adapted to different states of the seat body 1 , and the user can rest their arms on the armrest assembly 2 more comfortably when sitting in different postures, thereby improving the user's riding experience.

[0079] As shown in Figure 7, in one possible embodiment, the chair body 1 includes a seat 12 and a backrest 11, which is connected to the seat 12. The user can sit on the seat 12 and lean against the backrest 11. The backrest 11 and seat 12 can move relative to each other, and the angle of the seat 12 can also be adjusted. The main body 21 can be mounted 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. The controller analyzes and processes the detection results of the first Hall element and / or the second Hall element, thereby calculating 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, so that the main body 21 remains in a horizontal state.

[0081] This design allows the seat 12 and backrest 11 to be adjusted when the user adjusts the seat body 1. By changing the angles of the seat 12 and backrest 11, the seat body 1 can be placed in different positions. For example, the seat body 1 can be placed in a sitting position, a semi-reclining position, a reclining position, a zero-gravity reclining position, and other different positions. Furthermore, users of different body shapes and different sitting habits can adjust the seat body 1 to a position that suits them according to their needs. When the user adjusts the seat body 1, the seat body 1 may be in a non-preset position. Preset positions include the seat's initial position and the "zero-gravity" reclining position. Other positions, such as the semi-reclining position and the user-adjusted sitting position, are non-preset positions. Because different users have different posture requirements for the seat body 1, the embodiment of the present application mounts the body portion 21 to the backrest 11 so that when the user adjusts the seat body 1, the body portion 21 can move with the backrest 11. The drive member 23 drives the body portion 21 to maintain a horizontal position, meeting the user's armrest usage requirements, thereby improving the comfort and user experience of the seat.

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

[0083] The cup holder 3 facilitates the placement of items such as cups. Compared to separating the cup holder 3 from the armrest, such as on the vehicle's dashboard or console, integrating the cup holder 3 with the armrest assembly 2 makes it easier to place or retrieve items in the cup holder 3. As the user adjusts the position of the seat body 1, the cup holder 3 adjusts accordingly with the main body 21, allowing the user to place or retrieve items in the cup holder 3 regardless of their position. Furthermore, the solution provided in this embodiment of the application can maintain a horizontal position for the main body 21 via the drive member 23. Therefore, when the user adjusts the position of the seat body 1, the cup holder 3 located on the main body 21 also maintains a horizontal position. This reduces the possibility of items in the cup holder 3 falling or liquids spilling, thereby reducing the possibility of accidents such as burns or electrical hazards caused by spilled liquids, thereby improving safety and better meeting actual usage needs.

[0084] In a possible embodiment, the main body 21 has an accommodating cavity, and the cup holder 3 can move along the accommodating cavity, so that at least a portion of the cup holder 3 can extend or retract relative to the accommodating 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 can be retracted when not needed, thereby reducing the space occupied by the cup holder 3 and better meeting actual usage needs.

[0086] As shown in FIG7 , in one possible embodiment, the seat includes two armrest assemblies 2 , which are located on opposite sides of the seat body 1 along the width direction of the seat.

[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] As shown in FIG8 , the chair provided by the embodiment of the present application can output Hall signals of the backrest 11 and 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 seat basin 12 in real time based on the received Hall signals, and automatically selects the angle to which the armrest needs to be rotated in order 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 the 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 the user. 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 so that the armrest assembly 2 is in a horizontal state, which is conducive 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 angle of the current position of the backrest 11 can be detected, and the armrest assembly 2 can be adjusted according to the angle of the current position of the backrest 11 to make the armrest assembly 2 in a horizontal state, thereby improving the user's comfort.

[0098] In one possible embodiment, the seat may be provided with a first Hall element and a second Hall element, where 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. 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. The controller can calculate the current position angle of the backrest 11 based on the detection results of the first and second Hall elements, and control the drive 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 a horizontal level 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 the corresponding state directly after the user selects it, which is more convenient to use.

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

[0105] 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 1 can 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, 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] Typically, when the armrest assembly 2 is already horizontal and 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 the horizontal state, the controller can calculate the angle required for the armrest assembly 2 to rotate from the current state to the horizontal state, and calculate β based on the current position angle α of the seat body 1.

[0110] In a possible implementation, 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 welcome mode. When the vehicle is powered off, the controller may control at least one armrest assembly 2 to rotate to a predetermined angle between the armrest assembly 2 and the seat body 1, typically the armrest assembly 2 on the door side, until the body 21 is parallel to the backrest 11, to facilitate the user's exit. When the user enters the vehicle, whether the user is seated can be determined by whether the seat belt is inserted.

[0113] When the user gets off the vehicle, the judgment is usually based on whether the power is off. When the control is terminated based on whether the user has unplugged the seat belt, the seat belt is usually plugged in and out close to the armrest, so it is easy for the seat belt to collide with the user.

[0114] As shown in Figure 9, in one possible embodiment, when a user sits in the seat and begins controlling it, the main body 21 can be adjusted to a horizontal position to facilitate seating. The user can select a usage scenario to control the seat. When the user selects a preset usage scenario, the controller automatically adjusts the seat body 1 to a preset position and, during this adjustment, controls the armrest assembly 2 to maintain a horizontal position. If armrest assemblies 2 are provided on both sides of the seat, the controller controls both armrest assemblies 2 to adjust to a specified position, i.e., both armrest assemblies 2 are horizontal, ensuring that their support positions are aligned. If the user does not select a preset usage scenario and instead chooses to adjust the state of the seat body 1 themselves, the controller obtains the current angle of the seat body 1 in real time based on the first and second Hall elements, and controls the drive member 23 to rotate the main body 21, adjusting the state of the armrest assembly 2 in real time to maintain a horizontal position. Control ends when the vehicle loses power.

[0115] In actual use, since the armrest assembly 2 rotates and folds after the user gets off the vehicle, the user does not need to adjust the armrest assembly 2 to a horizontal position 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 position during the process of adjusting to the corresponding usage scenario.

[0116] As shown in FIG10 , the armrest on one side of the seat is in the stowed position to facilitate users getting on and off the vehicle.

[0117] An embodiment of the present application further provides a storage medium for storing the control method of the armrest assembly involved in any of the above items.

[0118] The embodiments of the present application provide a control method and storage medium for a seat, an automobile, and an armrest assembly, wherein the seat includes a seat body 1 and at least one armrest assembly 2, wherein the armrest assembly 2 includes a body portion 21, a transmission assembly 22, and a drive member 23, wherein the body portion 21 is mounted on the seat body 1, and the drive member 23 is connected to the body portion 21 via the transmission assembly 22. A control is used to receive the rotation angle detected by a 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. This design allows the body portion 21 to automatically maintain a horizontal state, thereby facilitating user use and improving the riding experience.

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

[0120] In zero-gravity or reclining positions, it is inconvenient to take and put the cup holder due to the limitation of human posture; in reclining position, the armrest angle is not level, which affects 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 holders with angle adaptive function was invented, which improves the comfort of armrest use and the convenience and safety of cup holder use.

[0121] The retractable cup holder and electrically movable armrest are integrated into the comfort seat, utilizing specific control logic to maintain a comfortable horizontal angle based on the seat's posture. This design is ideal for in-car environments and provides excellent ride comfort. The armrest integrates seamlessly with the seat itself, saving space and ensuring a comfortable interior experience. Suitable for zero-gravity seating, normal backrest and seat cushion angle adjustments, and in and out of the vehicle, the armrest maintains a comfortable horizontal angle in real time based on the seat's posture, improving ride comfort and ease of use. It also prevents electrical hazards and burns to passengers caused by spillage and tipping of the cup holder when the armrest rotates with the cup holder.

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

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

[0124] Control logic for the welcome mode: The armrest retracts upwards after the power is turned off when the vehicle exits. After the user fastens their seatbelt, the armrest automatically lowers to a horizontal position.

[0125] Seat with dual electric armrests and adaptive horizontal structure

[0126] The dual-armrest seat consists of an outer powered armrest and an inner powered adaptive armrest. The powered adaptive armrest consists of the armrest body, armrest frame, armrest outer plastic parts and covering, hidden cup holder and other functional parts.

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

[0128] The principle of 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 the armrest needs to rotate to the horizontal position. It then sends a signal to the armrest motor to drive the armrest Hall effect motor to rotate to a specific position (horizontal or near the horizontal position).

[0131] Adaptive movable armrest structure

[0132] The electric armrest consists of the armrest rotation structure, Hall effect motor and its transmission structure (reducer, transmission gears, recliner), and control unit (chair controller). The electric adaptive armrest body consists of the armrest body, armrest frame, armrest external plastic parts and covering, pop-up cup holder and other functional parts.

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

[0134] This control logic is used for an adaptive angle car seat armrest with a cup holder. Utilizing specialized control logic tailored to the in-car environment, the armrest's position and posture are automatically and dynamically adjusted during adjustment, maintaining a horizontal angle and preventing spillage in the cup holder. This design is suitable for achieving zero-gravity postures, as well as for users adjusting the seat back and cushion during normal riding.

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

[0136] The control logic for the onboard welcome mode retracts the armrest after the power is turned off. After the user buckles up and puts on their seatbelt, the armrest automatically lowers to a horizontal position, making it easier to insert and remove seatbelts and enhancing the riding experience.
