Description

Technical Field

[0001] This disclosure relates to vehicle components, and more specifically, to handrails. Background Technology

[0002] The vehicle can be equipped with passenger seats, and the seats can be equipped with armrests, allowing passengers to rest their arms on the armrests to improve riding comfort.

[0003] The armrest can be configured such that a single arm component is rotatably integrated into the seat. The seated passenger can manually adjust the armrest angle by rotating it. However, a drawback of this type of armrest is that the installation angle cannot be changed according to the passenger's seating posture, and manual operation may be inconvenient.

[0004] Furthermore, the armrest may be installed at the angle of the user's arm, corresponding to their seating posture; therefore, a separate mounting unit may be required if mobile devices are to be installed or used. Additionally, when an angled mounting member is located on the armrest, the member may damage the installed mobile device due to vehicle vibrations and movement.

[0005] The above description is intended only to better understand the background of this disclosure and should not be construed as an admission that it belongs to related technology known to a person of ordinary skill in the art. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned problems related to the related technologies. The object of the present invention is to provide a handrail structure in which the mounting members are located inside the housing and can be selectively deployed.

[0007] Another object of this disclosure is to provide a handrail structure in which a slider that moves together with a mounting member is integrally formed with a drive that provides driving force to the slider.

[0033] In the following description, embodiments of the present disclosure will be presented in more detail with reference to the accompanying drawings. Embodiments of the present disclosure may be modified in various ways, and the scope of the present disclosure should not be construed as limited to the following embodiments. These embodiments are provided to describe the present disclosure more completely to those skilled in the art.

[0034] The terms “…section,” “…unit,” “…module,” etc., used in this document refer to a unit part that processes at least one function or operation, wherein the unit part can be implemented by hardware (e.g., processor, memory, communication interface, input device, output device, etc.), software, or a combination of hardware and software.

[0035] For the purposes of this application and claims, the exemplary phrases “at least one of A, B, or C” or “at least one of A, B, or C” are used, which means “at least one A, or at least one B, or at least one C, or any combination of at least one A, at least one B, and at least one C.” Furthermore, exemplary phrases used herein, such as “A, B, or C,” “at least one of A, B, and C,” “at least one of A, B, or C,” etc., may refer to each listed item or all possible combinations of listed items. For example, “at least one of A or B” may refer to (1) at least one A; (2) at least one B; or (3) at least one A and at least one B.

[0036] The terminology used in this specification is for describing particular implementations and is not intended to limit the scope of implementations. Unless the context clearly indicates otherwise, singular expressions include plural expressions.

[0037] Furthermore, although the terms “first”, “second”, etc., may be used to distinguish these elements in this document due to their identical names, these elements are not limited to the order described below.

[0038] Furthermore, as used herein, "armrest" can include any construction that allows a seated passenger to rest his / her arm on it. For example, armrest in this disclosure can be interpreted as including structures such as consoles.

[0039] The controller can be implemented as a memory storing data for algorithms or a program implementing algorithms for controlling the operation of various components arranged in a vehicle, and a processor performing the aforementioned operations using the data stored in the memory. The memory and processor can each be implemented as separate chips. Alternatively, the memory and processor can be implemented as a single chip. For example, the controller may include at least one of an electronic control unit (ECU), a central processing unit (CPU), a microprocessor unit (MPU), a microcontroller unit (MCU), an application processor (AP), or any other form of processor known in the art. Furthermore, the controller may include a combination of software and hardware capable of operating on at least one application or program for performing processes according to embodiments of the present disclosure.

[0040] One or more embodiments of this disclosure will now be described in detail with reference to the accompanying drawings, wherein the same or corresponding components will be given the same reference numerals, and repeated descriptions will be omitted.

[0041] In the armrest structure, the mounting component (also called the base or equipment base) positioned at an angle corresponding to the user's sitting posture unfolds in response to the user's request.

[0042] Figure 1This is a perspective view showing an example vehicle seat including a partitioned integrated armrest 10.

[0043] As shown in the figure, the vehicle seat (also referred to as the vehicle seat assembly) may include at least one partition assembly for separating the seats. The partition assembly may include an armrest assembly 10, which is movable in the horizontal and / or vertical directions of the vehicle.

[0044] The partition assembly may include: a partition member (also called a separator) disposed on the frame; and a partition connector, which is coupled to the partition member to allow driving forces of the drive to be applied to the partition member. When driving forces of the drive are applied, the partition member can be deployed along the horizontal and / or vertical direction of the vehicle via the partition connector.

[0045] Furthermore, the armrest assembly 10 may optionally be movably positioned along the partition member. The armrest portion of the armrest assembly 10 may support a user's arm thereon (e.g., a user's arm may rest on the armrest portion of the armrest assembly 10). If a rotational force from the drive is applied to the armrest portion of the armrest assembly 10, the armrest portion of the armrest assembly 10 may move in the horizontal and / or vertical directions of the vehicle.

[0046] The controller may be a vehicle control unit that includes an electronic control unit (ECU) (also known as a seat control unit). The controller may drive the partition assembly and / or armrest assembly 10 in response to user requests (e.g., user input via a user interface such as a knob, button, slider, push rod, etc.). If a user request is received to drive the seat tilt or unfold the partition assembly, the controller may supply power to the drive from the vehicle battery.

[0047] The controller (e.g., an ECU or any other controller for driving a drive or motor to move one or more components of the armrest assembly 10) can be implemented by having one or more electric motors (e.g., DC motors), one or more switches, one or more relays, one or more microcontrollers, one or more memories, one or more position sensors (e.g., potentiometers, Hall effect sensors, etc.), one or more wiring harnesses, etc. connected to the vehicle's electrical system.

[0048] In this disclosure, references to components, units, or modules generally refer to items that can be logically combined to perform a function or a set of related functions. The same reference numerals are generally used to refer to the same or similar components. Components, units, and modules can be implemented in software, hardware, or a combination of software and hardware. The aforementioned components, units, modules, and / or functions can be implemented and / or performed by one or more processors. For example, components, units, and / or modules may include processors, microprocessors, graphics processing units, logic circuits, application-specific circuits, application-specific integrated circuits, programmable array logic, field-programmable gate arrays, controllers, microcontrollers, and / or other suitable hardware. Components, units, and / or modules may also include, for example, software control modules implemented as processors or logic circuits. Components, units, and / or modules may include memory or otherwise accessible memory, such as one or more non-transitory computer-readable storage media, such as random access memory, read-only memory, electrically erasable programmable read-only memory, erasable programmable read-only memory, flash memory / other storage devices, data registers, databases, and / or other suitable hardware. One or more storage media may include any or all tangible memory such as computers, processors, or related modules such as various semiconductor memories, tape drives, disk drives, etc., which can provide non-transient storage for software programming at any time.

[0049] In at least some implementations, the driver and / or one or more controllers can be implemented as a processor and memory. "Processor" should be broadly understood to include general-purpose processors, central processing units (CPUs), microprocessors, digital signal processors (DSPs), microcontrollers, state machines, etc. In some contexts, "processor" can refer to application-specific integrated circuits (ASICs), programmable logic devices (PLDs), or field-programmable gate arrays (FPGAs). For example, "processor" can refer to a combination of processing devices, such as a combination of a DSP and a microprocessor, a combination of multiple microprocessors, a combination of one or more microprocessors with a DSP core, or any other such combination. Furthermore, "memory" should be broadly interpreted to include any electronic component capable of storing electronic information. "Memory" can refer to various types of processor-readable media, such as random access memory (RAM), read-only memory (ROM), and non-volatile random access memory. Memory can be in a state of electronic communication with the processor when the processor can read information from the memory and / or record information in the memory. Memory integrated into the processor is in a state of electronic communication with the processor.

[0050] Seat tilting refers to a seat positioning operation in which the seat back extends backward beyond a set angle (e.g., a threshold angle). In response to the seat tilting operation, the seat cushion can be raised at the front, causing the seat cushion to form a predetermined angle relative to its initial position.

[0051] In addition, the controller can adjust the pin of the position adjuster to set the movement of the handrail assembly 10 in conjunction with or optionally separately from the partition member.

[0052] Armrest 10 may be disposed on at least one side of the seat and has an opening 110 at its front end through which a mounting member may be inserted and unfolded. Armrest 10 may include an upper cover 120a and a lower cover 120b (collectively referred to as cover 120), and a housing 100 located between the upper cover 120a and the lower cover 120b. The mounting member (also referred to as a base or device base) 200 located in the housing 100 and facing the opening 110 may include a button 600 capable of receiving user input. The button 600 may be located at the end of the mounting member 200 facing the opening 110.

[0053] Figure 2 and Figure 3 This is a diagram illustrating an example handrail structure 10.

[0054] The armrest structure (also called an armrest) 10 can be located on a structure such as a console that is adjacent to the user. Furthermore, as... Figure 2 As shown, the armrest structure 10 may include an upper cover 120a and a lower cover 120b (which constitute a console-like structure), and a housing 100 fixed between the upper cover 120a and the lower cover 120b. The housing 100 may have an opening 110 at its front end. A mounting member 200 may be located in the opening 110. The mounting member 200 may be mounted and positioned within the housing 100 to have (e.g., form) a first set (e.g., predetermined) angle relative to the opening 110 and the hinge portion 210 of the housing 100.

[0055] like Figure 3 As shown, the handrail structure 10 may include a slider 300, which can move together with the mounting member 200 in the front-rear direction (e.g., the length direction) of the housing 100. The handrail structure may include an actuator 400 disposed on the slider 300 to provide a length-direction moving force.

[0056] The hinge portion 210 can be rotatably coupled to the mounting member 200 such that the front end of the hinge portion 210 is located on the upper surface of the housing 100 facing the opening 110, and the rear end of the hinge portion 210 is coupled to the slider 300. Furthermore, the mounting member 200 may include a latch 220 at its rear end, facing the latch bracket 500 fixed to the housing 100. Additionally, the mounting member 200 may be provided with a retainer for securing (e.g., mounting) equipment (e.g., a mobile device). The retainer can be used to secure (e.g., mount) the equipment using, for example, clamps, fasteners, magnets, etc. The retainer can be fixed to one side of the mounting member 200 to apply a spring force to secure the mobile device, or to force the mobile device to remain on the mounting member 200 via a linkage structure.

[0057] If button 600 is pressed, latch 220 can disengage from latch support 500. Although not shown, button 600 may include multiple links that allow latch 220 to be rotatably opened to disengage from latch support 500. Alternatively, latch 220 may include a push-pull engagement structure that allows latch 220 to unlock in response to pressing button 600.

[0058] A rack 140 (also called a gear rack) can be disposed at the bottom of the housing 100 along its length. Racks 140 can be disposed in pairs at both ends of the housing 100 in its width direction, and a slider 300 can move along the rack 140 in the length direction of the housing 100. The slider 300 can be configured to allow a hinge portion 210 disposed on the upper surface of the housing 100, a sliding bracket 310 disposed at the bottom of the housing 100, and a drive 400 as a whole to move along a slot 150 of the housing 100. The hinge portion 210 can be located above the slot 150, and the sliding bracket 310 can be located below the slot 150, such that the unfolding of the mounting member 200 is configured to correspond to the length of the slot 150.

[0059] The slider 300 may include a damper 320 that engages with the rack 140, and a sliding bracket 310 that fixes the damper 320 and the actuator 400. Furthermore, the sliding bracket 310 may engage with a hinge portion 210 via a housing 100. The hinge portion 210 is fixed to the mounting member 200 at the bottom of the housing and to the rear end of the mounting member 200 on the upper surface of the housing 100. Thus, the slider 300, the hinge portion 210, and the mounting member 200 can operate as a single unit.

[0060] The damper 320 can engage with the rack 140 to control the deployment speed of the mounting member 200 in response to a driving force from the actuator 400. The damper 320 may include an eccentric damper, a fluid damper, etc., and may be coupled to the sliding bracket 310 for rotation along the rack 140.

[0061] The driver 400 may include a spring 420 fixed to the front end of the housing 100, and a spring housing 410 (with the spring 420 internally wound on the spring housing), the spring housing 410 being fixedly positioned on the sliding bracket 310. The driver 400 may include a motor, servo mechanism, etc., capable of mechanically moving one or more components (e.g., mounting member 200, slider 300, etc.).

[0062] When the mounting member 200 is retracted into the housing 100 (e.g., the retracted position of the mounting member 200), the spring 420 can be deployed and positioned between the housing 100 and the sliding bracket 310. Thus, the spring 420 can apply tension to the sliding member 300 in the direction in which the spring 420 is wound inside the spring housing 410. In other words, when the mounting member 200 is installed in the housing 100, the spring 420 can apply a spring force to the sliding member 300 in the direction in which the mounting member 200 is deployed.

[0063] Alternatively, the spring 420 can be wound or unwound by a motor coupled to the spring housing 410, and the mounting member 200 can be unwound from or mounted into the housing 100 depending on the direction of the motor's drive.

[0064] If the actuator 400 moves in the direction in which the spring 420 is wound, the mounting member 200 can unfold to the outside of the armrest assembly along the opening 110 of the housing 100. Furthermore, if an external force or motor drive force is applied in the unfolding direction of the spring 420, the latch 220 can be secured to the latch bracket 500 to keep the mounting member 200 retracted into the housing 100.

[0065] Figure 4 This is a side cross-sectional view showing the mounting component 200 retracted into the housing 100.

[0066] The cover 120 constituting the armrest assembly may include an upper cover 120a and a lower cover 120b (collectively referred to as cover 120), and the housing 100 may be fixed to the upper cover 120a and the lower cover 120b. The housing 100 may be partially fixed to the cover 120, and the housing may have an opening 110 on the side where the mounting member 200 is extended. The opening 110 may be provided through the cover 120 and the housing 100, and may be positioned such that when the mounting member 200 is retracted into the housing 100, the button 600 of the mounting member 200 is exposed through the opening 110.

[0067] With the mounting member 200 retracted, the slider 300 can be located near the inside of the housing 100, away from the opening 110. Furthermore, the actuator 400 can be fixedly located on the slider 300 with the spring 420 extended. A first end of the spring 420 can be engaged with the housing 100 or cover 120 adjacent to the opening 110, and a second end is at least partially wound around the spring housing 410. The spring 420 can engage with the rotating shaft of a motor within the spring housing 410 to receive driving force. Alternatively, the spring 420 can be subjected to the rotational force of a helical spring formed within the spring housing 410, and tension can be applied to the spring 420 in the direction in which it is wound around the inside of the spring housing 410.

[0068] Furthermore, the damper 320 of the slider 300 can engage with the rack 140, which is arranged in pairs on both sides of the spring housing 410 to extend in the length direction of the housing 100. As the damper moves along the length direction of the rack 140 in response to the movement of the mounting member 200, the damper 320 can provide resistance to reduce the deployment speed of the mounting member 200.

[0069] Furthermore, the hinge 210 can engage with the sliding bracket 310. The hinge 210 can be located at the distal end of the mounting member 200 in the unfolding direction. The hinge 210 can be positioned such that the side unfolded relative to the inner end of the cover 120 can rotate in the vertical direction.

[0070] Furthermore, the positions of the bearing 130 and hinge 210 located adjacent to the opening 110 in the housing 100 can set the angle of the mounting member 200 relative to the length direction of the housing 100. In the retracted state, the mounting member 200 formed by the bearing 130 and hinge 210 can be configured to have (e.g., form) a first predetermined angle. This first predetermined angle could be, for example, 3.2 degrees along the height direction relative to the length direction of the housing 100. The mounting member 200 can be housed between the hinge 210 and the opening 110 in the retracted state.

[0071] The latch bracket 500 may be disposed in the housing 100 in a manner that interlocks with the inner end of the mounting member 200. The mounting member 200 may include a latch 220 at the end facing the latch bracket 500. The latch 220 may include a push-pull engagement structure such that the latch 220 and the latch bracket 500 may engage or disengage in response to pressing the button 600.

[0072] Therefore, even when the latch 220 is engaged with the latch bracket 500, the spring 420 of the actuator 400 can apply tension to the mounting member 200 and the slider 300 in the direction that the slider 300 approaches the opening 110. Furthermore, when the latch 220 disengages from the latch bracket 500 in response to the unlock input of the button 600, the mounting member 200 can be extended to the outside of the opening 110 by the tension of the spring 420.

[0073] Figure 5 This is a side cross-sectional view showing the handrail structure 10 with the mounting component 200 unfolded.

[0074] In response to an input from the user button 600 or an input from the controller to unfold the mounting member 200, the mounting member 200 can be unfolded along the opening 110 of the housing 100. Furthermore, the latch 220 can disengage from the latch bracket 500, and the disengaged mounting member 200 can slide along the groove 150 of the housing 100 toward the front end where the opening 100 is located, under the tension of the actuator 400 and together with the slider 300.

[0075] Furthermore, with the mounting member 200 retracted into the housing 100, the front end of the spring 420 can be fixed to the housing 100 or cover 120 adjacent to the opening 110, and the elastic force of the unfolded spring 420 returning elastically to the spring housing 410 can be applied to the slider 300. Therefore, the elastic force applied in the direction in which the spring 420 is wound around the inside of the spring housing 410 causes the mounting member 200, the slider 300, and the actuator 400 coupled to the slider 300 to move together toward the front end of the housing 100.

[0076] Furthermore, the hinge 210 at one end of the mounting member 200 located on the upper surface of the housing 100 can engage with the sliding bracket 310 located at the bottom of the housing 100 relative to the groove 150 in the housing 100, so that the mounting member 200 extends outward along the shape of the groove 150 to the outside of the opening 110.

[0077] Furthermore, compared to the retracted state of the mounting member 200, the bearing 130 and the hinge portion 210 can be positioned close together along the length of the housing 100. The height difference between the bearing 130 and the hinge portion 210 allows the mounting member 200 to extend outward from the opening 110 to have (e.g., form) a second set (e.g., predetermined) angle. The second set angle can be set to, for example, 35 degrees. However, the second set angle can vary depending on the position of the handrail structure 10, and therefore the second set angle can vary with the height difference between the bearing 130 and the hinge portion 210.

[0078] The damper 320 can be configured to rotate in contact with the rack 140 as the slider 300 moves toward the front end of the housing 100. Based on the frictional force generated between the damper 320 and the rack 140 and the rotational resistance of the resistance fluid disposed in the damper 320, an operating force can be applied in the opposite direction to the force applied from the actuator 400 to the mounting member 200. Thus, the damper 320 can control the deployment speed of the mounting member 200.

[0079] In one aspect of this disclosure, the handrail structure includes: a housing having an opening; a mounting member located inside the housing and extending along the opening; a slider engaging with the mounting member to move along the housing together with the mounting member; and a drive engaging with the slider to provide a driving force along the extension direction of the mounting member.

[0080] The handrail structure may also include a rack located within the housing.

[0081] The sliding element may include: a damper that meshes with a rack; and a sliding support on which the actuator and the damper are located.

[0082] The racks can be arranged in pairs at opposite ends of the sliding bracket along the length of the housing.

[0084] The handrail structure may include a button located at one end of the mounting member adjacent to the opening, wherein a latch disengages from a latch support in response to input of the button.

[0085] The handrail structure may also include a hinge, which serves as a pivot point for the mounting member and is located at the rear end of the mounting member to move together with the sliding support.

[0086] The mounting member can be configured to have a first predetermined angle relative to the hinge when mounted between the hinge and the opening, and a second predetermined angle relative to the hinge when unfolded.

[0087] The actuator may include: a spring, a first end of which is fixed to the front end of a housing and a second end of which is fixed to a sliding bracket; and a spring housing for accommodating the spring, wherein at least a portion of the spring is wound inside the spring housing.

[0088] The handrail structure may include a motor located on a sliding support to cause a spring to coil inside a spring housing during motor operation.

[0089] The handrail structure may also include bearings, which are located in the opening of the housing in a manner facing the mounting components.

[0090] The sliding element can move together with the mounting component along a groove extending in the length direction of the housing.

[0091] Through the combination and usage of the above-described embodiments, this disclosure has the following effects.

[0092] The handrail structure is configured to allow the mounting components to unfold at selectable angles, thus providing a configuration that can be operated in response to the user's position.

[0093] The handrail structure is configured such that when not in use, the mounting components are housed within the casing, thereby improving the aesthetics of the handrail structure.

[0094] The above detailed description is an illustrative illustration of this disclosure.
