Detailed Implementation

[0023] The implementation and use of specific embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of particular ways of implementing and using the invention, and are not intended to limit the scope of the invention.

[0024] In this specification, the descriptions of the structural positions of various components, such as "up," "down," "left," and "right," are not absolute but relative. These directional descriptions are appropriate when the components are arranged as shown in the figures, but they should be changed accordingly when the positions of the components change.

[0025] In this specification, "vehicle" means a device that can be used to transport people and / or goods. As an example, a vehicle can be a car, such as a sedan, bus, or truck, but those skilled in the art will understand that a vehicle is not limited to these and can also be other forms of transport such as motorcycles, ships, or aircraft.

[0026] In this manual, the X-axis refers to the fore-aft direction of the vehicle seat, i.e., the length direction of the vehicle and the longitudinal direction of the seat. The armrest's fore-aft position relative to the seat can be adjusted by translating the support member along the X-axis. The Y-axis refers to the left-right direction of the vehicle seat, i.e., the width direction of the vehicle and the lateral direction of the seat. "Rotating about a rotation axis extending along the Y-axis" means that the armrest rotates about an axis extending horizontally in the left-right direction, thereby changing the tilt angle of the support member, for example, raising one end upwards or lowering it flat. The Z-axis refers to the vertical direction, i.e., the up-down direction perpendicular to the ground. The armrest's height can be raised or lowered by translating the support member approximately along the Z-axis, allowing it to switch between a lower stowage position and a higher raised position.

[0027] Furthermore, in this specification, unless otherwise expressly specified and limited, terms such as "assembly" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this specification according to the specific circumstances.

[0028] A preferred embodiment of the present invention will now be described with reference to the accompanying drawings.

[0029] like Figure 1 As shown, the present invention provides a vehicle seat 27, including a seat cushion portion for supporting the occupant's buttocks, a seat back 28 connected to the seat cushion, and armrest portions 29 integrated on both sides of the seat. Each armrest portion has a side frame inside, and the armrest assembly 100 is mounted on the side frame and integrated with the seat system.

[0030] like Figures 2 to 4 As shown, the armrest assembly 100 includes a base 11 fixedly connected to the vehicle floor or seat frame, a support member for supporting the occupant's arms, and an adjustment mechanism. The base 11 is adapted to be fixed to the seat frame by means of bolts or welding. The support member can be formed as a multi-layer structure, for example including a cover 1, a foam 2, and an outer cover 3.

[0031] The adjustment mechanism is connected to the base and the support member and is configured to drive the support member to move and rotate relative to the base. Specifically, according to a preferred embodiment of the invention, the adjustment mechanism includes a lifting mechanism, a rotating mechanism, and a translation mechanism. These will be described in detail below.

[0032] like Figure 5 As shown, the lifting mechanism is configured to drive the support member to translate relative to the base 11 generally along the Z direction between a stowed position (i.e., a position hidden in the armrest portion 29 so that it is basically invisible inside the carriage) and a raised position.

[0033] like Figure 4 , Figure 6 and Figure 7 As shown, in this embodiment, the lifting mechanism includes a first motor 13, a first lead screw 131, a first nut 14, and a first bracket 18.

[0034] More specifically, guide rails 12 extending approximately along the Z-direction are respectively provided on both sides of the base 11. The first bracket 18 is slidably engaged with the guide rails 12 and connected to the support member, and can be driven by the first motor 13 to translate approximately along the Z-direction relative to the base 11. First decorative panels 25 and 26 are respectively mounted on both sides of the first bracket 18.

[0035] The first motor 13 is fixedly mounted on the base 11, and the mounting gap is adjusted by a metal shim 15 to ensure positioning accuracy and prevent wear. A rubber shim 16 is also used for vibration reduction, noise reduction, and buffering. The first lead screw 131 is connected to the first motor 13 and extends approximately along the Z-direction. The first nut 14 is fixedly connected to the first bracket 18 by a screw 19 and threadedly engaged with the first lead screw 131. This allows the nut to move vertically along the first lead screw 131 when the first motor 13 drives it to rotate, thus causing the first bracket 18 and all components above it to move smoothly approximately along the Z-direction, thereby achieving the lifting and lowering adjustment of the support component.

[0036] like Figure 8 As shown, the support member is directly or indirectly rotatably linked to the first bracket 18, and the rotating mechanism is configured to drive the support member to rotate relative to the first bracket 18 about a rotation axis extending along the Y direction, so as to adjust the tilt angle of the support member.

[0037] like Figure 4 , Figures 9 to 11 As shown, in this embodiment, the rotating mechanism includes a second motor 20, a second lead screw 201, a second bracket 9, and a guide member 240.

[0038] The second motor 20 is fixedly mounted on the first bracket 18 by screws 21. The second lead screw 201 is connected to the second motor 20 so that it can move axially when driven to rotate by the second motor 20.

[0039] The second bracket 9 is fixedly connected to the support member on one hand and rotatably connected to the first bracket 18 on the other, and can be driven by the second motor 20 to rotate relative to the first bracket 18 about a rotation axis. Specifically, the second bracket 9 includes a body 91 and a first mounting portion 92 and a second mounting portion 93 extending downward from the edge of the body 9. The body 91 is connected to the support member, and the first mounting portion 92 is rotatably connected to the first bracket 18 by a nut 231 and a bolt 22. A second decorative plate 8 is fitted to the end of the second bracket 20, and a third decorative plate 10 is fitted to the bottom of the second bracket 20. According to another embodiment, the first mounting portion 92 and the first bracket 18 can also be directly rotatably connected by a pivot pin.

[0040] The guide member 240 is fixedly connected to the top end of the second lead screw 201 and can slide relative to the second bracket 9 to push the second bracket 9 to rotate when the second lead screw 201 moves axially. Preferably, the guide member 240 is configured as a pin consisting of a nut 232 and a bolt 24, and the second mounting portion 93 is provided with a groove 931 for the pin to slide along. According to a variation, the positions of the pin and the groove can be interchanged, i.e., the guide member 240 is configured as a groove, and the second mounting portion 93 is provided with a pin that can slide along the groove.

[0041] When the angle of the support needs to be adjusted, the second motor 20 drives the second lead screw 201 to rotate and translate axially. The guide 240 translates axially with the second lead screw 201 and slides relative to it within the groove 931, thereby causing the second bracket 9 to rotate about a rotation axis extending along the Y direction. This changes the angle between the support connected to the second bracket 9 and the horizontal plane. During rotation, the relative displacement between the guide 240 and the second mounting part 93 through the groove 931 compensates for motion interference caused by the arcuate movement of the second bracket 9, ensuring smooth and stable rotation of the second bracket 9. Preferably, the rotation angle of the support relative to the horizontal plane is in the range of 0° to 15°, more preferably 5° to 10°, for example, approximately 7°.

[0042] like Figure 12 As shown, the translation mechanism is configured to drive the support member to translate relative to the base 11 along the X-direction of the seat to accommodate the fore-aft position requirements of different occupants.

[0043] like Figure 4 and Figure 13 As shown, in this embodiment, the translation mechanism includes a third motor 5, a telescopic rod 51, and a slide rail assembly 4. The third motor 5 is assembled to the second bracket 9 by screws 7.

[0044] like Figure 13As shown, the slide rail assembly 4 includes a first sliding member 41 and a second sliding member 42. According to one embodiment, the first sliding member 41 and the second sliding member 42 are respectively configured as a fixed rail 41 and a movable rail 42. The fixed rail 41 is mounted on a second bracket 9 via screws 6 to connect to the base 11, and the movable rail 42 is connected to a support member and can be driven by a third motor 5 to translate relative to the fixed rail 41 in the X direction. The third motor 5 is mounted on the support member or on the second bracket 9. According to another embodiment, the sliding component 4 can also be configured as a combination of a groove and a slider. For example, the first slider 41 can be configured as a fixed base with a guide groove, and the second slider 42 can be configured as a slider embedded in the guide groove. Alternatively, the first slider 41 can be configured as a guide rail, and the second slider 42 can be configured as a slider sleeved on the guide rail. As long as the two can form a linear guiding fit along the X direction and can generate relative displacement under the drive of the third motor 5, it is acceptable.

[0045] like Figure 13 and Figure 14 As shown, the telescopic rod 51 is connected to a third motor 5 so that it can be driven by the third motor 5 to extend and retract along the X direction, and the moving rail 42 is fixedly connected to the telescopic rod 51 so that it can translate relative to the fixed rail 41 along the X direction when the telescopic rod 51 extends and retracts. Figures 13 to 18 As shown, when forward and backward adjustment is required, the third motor 5 operates to drive the moving rail 42, together with the support member, to slide forward and backward along the X direction via the telescopic rod 51. Alternatively, the telescopic rod and the third motor can be replaced by a planetary roller screw-brushless hollow cup motor to drive the moving rail, together with the support member, to slide forward and backward along the X direction.

[0046] Furthermore, the armrest assembly 100 of the present invention preferably includes a control unit and a signal input module for implementing electric control. The control unit is electrically connected to the signal input module and the adjustment mechanism to control the adjustment mechanism to drive the support member to translate and / or rotate relative to the base in response to the signal input module. It is understood that the control unit and signal input module are not limited to being mounted on the armrest assembly, but may be located in other positions, such as the seat base, center console, door panel, next to the dashboard, remote control, or mobile terminal.

[0047] Preferably, the adjustment mechanism is configured to execute sequential control logic. The adjustment mechanism is configured to first drive the support member to translate approximately along the Z-axis from its stowed position to its raised position relative to the base. Upon reaching the raised position, the support member has space for rotation and translation along the X-axis, without interfering with surrounding components. Then, the adjustment mechanism can drive the support member to rotate relative to the base 11 about a rotation axis extending along the Y-axis, and / or drive the support member to translate relative to the base 11 along the X-axis. Sequential control of the support member avoids motion interference and ensures structural reliability. Parallel control can shorten the total adjustment time and improve the user experience.

[0048] Furthermore, it should be noted that the control sequence of the present invention is not limited to the above-described process of "first lifting approximately along the Z-axis, then translating approximately along the X-axis, and then rotating". For example, the control sequence could be to first translate approximately along the X-axis, then lift approximately along the Z-axis, and finally rotate; or it could be to first rotate, then lift approximately along the Z-axis, and finally translate approximately along the X-axis.

[0049] According to another implementation variation, simultaneous lifting and rotation / translation can be allowed based on the control logic, or the sequential constraint can be removed to improve adjustment efficiency. Preferably, the support member can rotate while translating along the X-axis, that is, the translation mechanism and the rotation mechanism are linked. The linkage can be achieved through a mechanical transmission chain, or the speed and stroke of each motor can be coordinated through an electronic control program to adapt to the comprehensive needs of different occupants for support position and angle.

[0050] Furthermore, the armrest assembly 100 preferably includes a storage module for storing at least one default position of the support member relative to the base 11. The storage module records one or more default positions of the support member relative to the base, such as a personalized position preset by the occupant or a factory-calibrated position. Preferably, the storage module may have a built-in power-off retention memory and support storing multiple sets of user configurations, such as seat memories for different drivers. This allows personalized settings to be retained and quickly recalled even after a power outage, reducing repetitive adjustment operations and improving convenience in multi-user scenarios.

[0051] The following is a brief description of the three modes that the control unit of the handrail assembly 100 can execute.

[0052] One-button mode: In response to a default position signal from the signal input module, such as in response to a passenger operating the default position button, the control adjustment mechanism drives the support member to translate approximately along the Z direction relative to the base 11, and / or drives the support member to rotate relative to the base about a rotation axis extending along the Y direction, and / or drives the support member to translate relative to the base along the X direction, so that the support member reaches the default position desired by the passenger.

[0053] Independent Adjustment Mode: In response to at least one manual input signal from the signal input module, such as in response to a passenger operating at least one position adjustment device, the control mechanism drives the support member to translate approximately along the Z-axis relative to the base 11, and / or drives the support member to rotate about a rotation axis extending along the Y-axis relative to the base 11, and / or drives the support member to translate along the X-axis relative to the base, so that the support member reaches the position desired by the passenger. Preferably, after manual adjustment to the desired position, the occupant can trigger a storage command. The control unit stores the current height value, angle value, and fore-aft position parameters as the default position in the storage module for subsequent activation of the one-button mode.

[0054] The "independent adjustment mode" utilizes three independent motors to drive the lifting, rotation, and translation movements respectively, without interference between them. This allows the support components to achieve multi-degree-of-freedom adjustment, concealing themselves within the side frame when not in use and adapting to the occupant's arm posture in all directions when in use. This design not only effectively saves cabin space but also significantly enhances the overall user experience of the seat, achieving interference-free, low-noise, and highly reliable multi-degree-of-freedom adjustment within the limited cabin environment.

[0055] Adaptive adjustment mode: When the control unit detects that the backrest of the vehicle seat is rotated, such as when the occupant adjusts their sitting posture by leaning back or forward, the automatic control adjustment mechanism drives the support to translate relative to the base in the X direction to keep the support in contact with the current occupant's arm at all times.

[0056] By controlling the sequence of lifting, rotation, and translation via the control unit, interference between the support components and surrounding components can be effectively avoided, ensuring structural reliability. Parallel adjustments can also be achieved according to the control logic, shortening the total adjustment time and improving operational efficiency. Furthermore, a storage module and multiple control modes, including one-button mode, manual adjustment mode, and adaptive adjustment mode, are provided. Users can preset default positions that are retained even after power failure, allowing for quick recall of personalized settings and reducing repetitive adjustments. The adaptive adjustment mode automatically adjusts the support components when the seat back angle changes, ensuring the support components always remain in close contact with the occupant's arms, further enhancing the level of intelligence and comfort.

However, it is understood that those skilled in the art can make various changes and improvements to the above-disclosed concept under the creative idea of ​​the present invention, but all of these shall fall within the protection scope of the present invention.
