Description

Technical Field

[0001] This utility model relates to the field of automotive armrest technology, and in particular to an adjustable armrest and automotive seat system. Background Technology

[0002] As an important component of automobiles, the center armrest is increasingly attracting attention for its multifunctionality and comfort. However, some cars have non-adjustable center armrests. Even after adjusting the car seat (e.g., adjusting fore-and-aft position, activating zero-gravity mode, or bed mode), the center armrest remains in the same position, resulting in poor elbow support and a less than ideal user experience.

[0003] Therefore, some cars on the market now have adjustable center armrests. Most of them move back and forth on a fixed track through various control methods (such as voice control, central control screen switch, etc.). When the user switches to the bed mode, although the position of the center armrest changes, its height is still only suitable for the user to use in an upright position. The elbow can support the center armrest, but the comfort is poor. Moreover, for some height-adjustable armrests, the user needs to control the in-vehicle control system multiple times to adjust it, and it is difficult to adjust it to a comfortable position, which reduces the user experience. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, the technical problem this utility model aims to solve is to provide an adjustable armrest and car seat system that allows for sliding adjustment of the armrest support relative to the armrest housing in various car seat postures, providing support for the passenger's elbows and adapting to different car seat postures. The technical solution adopted by this utility model to solve its technical problem is to provide an adjustable armrest, comprising:

[0005] Armrest housing;

[0006] Handrail support, which is slidably mounted on the handrail housing;

[0007] A slide rail assembly is disposed between the handrail support and the handrail housing, and includes: an outer slide rail fixed to the handrail housing; and an inner slide rail fixed to the handrail support and slidably disposed on the outer slide rail.

[0008] When the handrail support slides relative to the handrail housing, the inner slide rail slides along the outer slide rail.

[0009] Furthermore, the slide rail assembly also includes:

[0010] Multiple ball bearings are disposed between the outer slide rail and the inner slide rail;

[0011] The inner slide rail is provided with a through hole, and the ball bearing passes through the through hole and abuts against the outer slide rail;

[0012] When the inner slide rail slides relative to the outer slide rail, the multiple balls roll.

[0013] Furthermore, the armrest box is provided with a guide slope, and the armrest support is provided with a sliding surface that cooperates with the guide slope, and the sliding surface is slidably engaged with the guide slope;

[0014] When the handrail support moves relative to the handrail housing, the sliding surface slides along the guide ramp, and the position and height of the handrail support on the handrail housing change.

[0015] Furthermore, a first limiting piece is provided at one end of the inner slide rail, and a second limiting piece is provided at the other end of the inner slide rail;

[0016] The first limiting piece and the second limiting piece are used to limit the travel of the inner slide rail along the outer slide rail.

[0017] Furthermore, it also includes a motor and a lead screw, the motor being mounted on the armrest housing and the lead screw being mounted on the output end of the motor;

[0018] The handrail support is provided with a nut structure, which is set on the lead screw and forms a lead screw and nut mechanism with the lead screw;

[0019] The slide rail assembly is inclined, and the lead screw is set in a direction parallel to the slide rail assembly.

[0020] Furthermore, the armrest housing also includes a connecting seat, on which the motor and the lead screw are both mounted;

[0021] The outer slide rail is fixed on the connecting seat.

[0022] Furthermore, it also includes:

[0023] A tabletop assembly, movably disposed within the armrest housing, includes a tabletop and a push rod, the push rod being connected to the tabletop; the tabletop slides radially along the push rod.

[0024] A refrigerator is disposed in the armrest box.

[0025] This utility model also proposes an automotive seat system, comprising:

[0026] The first and second electric slide rails are arranged in parallel.

[0027] A car seat is mounted on the first electric slide rail, and the first electric slide rail can drive the car seat;

[0028] As described above, the adjustable armrest housing is mounted on the second electric slide rail, and the second electric slide rail can drive the armrest housing.

[0029] Furthermore, it also includes a controller;

[0030] The car seat has a zero-gravity mode;

[0031] When the car seat switches from the designed position to zero gravity mode, the controller controls the armrest support to slide relative to the armrest box and controls the second electric slide rail to make the armrest box slide.

[0032] Furthermore, the length of the second electric slide rail is longer than the length of the first electric slide rail.

[0033] Compared with the prior art, the present invention has at least the following beneficial effects:

[0034] In this invention, the armrest support can be slidably adjusted relative to the armrest housing. Whether the car seat is in a specific position (e.g., the designed position, zero-gravity position, or bed position), the armrest support can be slidably adjusted to provide elbow support for the passenger, ensuring that the armrest support provides elbow support regardless of the car seat's position, thus improving passenger comfort. A slide rail assembly is disposed between the armrest support and the armrest housing. The outer slide rail is fixed to the armrest housing, and the inner slide rail is fixed to the armrest support and slidably mounted on the outer slide rail, enabling the armrest support to be slidably adjusted on the armrest housing. When the armrest support slides relative to the armrest housing, the inner slide rail slides along the outer slide rail, resulting in a smooth and stable sliding motion and a good user experience.

[0035] In this invention, the armrest housing is provided with a guide slope, and the armrest support is provided with a sliding surface that cooperates with the guide slope. The sliding surface and the guide slope slide in cooperation, which can ensure the accurate positioning of the armrest support during movement, and the sliding process is smoother and more continuous. When the armrest support moves relative to the armrest housing, the sliding surface slides along the guide slope. The slope makes the armrest support move continuously and gradually during movement, so as to realize the change of the position and height of the armrest support on the armrest housing. Moreover, the sliding of the armrest support on the armrest housing can realize the fine adjustment of the position of the adjustable armrest.

[0036] In this invention, the car seat system includes a first and second electric slide rail arranged in parallel, a car seat, and a controller. The car seat has a zero-gravity mode. When the car seat switches from its designed position to zero-gravity mode, the controller controls the armrest support to slide relative to the armrest box and controls the second electric slide rail to slide the armrest box. That is, when the car seat is in zero-gravity mode, the backrest and seat cushion will rotate at a certain angle to reduce the user's body pressure. At this time, the controller controls the second electric slide rail to slide the armrest box, and its position can match the position of the car seat. At the same time, the controller controls the armrest support to slide on the armrest box to adjust the position and height of the armrest support to ensure that the user's elbows are supported in various postures. Furthermore, the controller controls the second electric slide rail and armrest support to automatically adjust. The adjusted position and height of the armrest support conform to ergonomics, providing high user comfort, and eliminating the need for manual adjustment by the user. The second electric slide rail is longer than the first electric slide rail, which can meet the adjustment of the adjustable armrests within the entire range of the car seat's forward and backward travel. That is, no matter where the car seat is moved, the adjustable armrests can slide to the side of the car seat to achieve full range adjustment. Attached Figure Description

[0055] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0056] Example 1:

[0057] like Figures 1-6As shown, an adjustable handrail in this embodiment mainly includes: a handrail housing 1, a handrail support 2, and a slide rail assembly 3. The handrail support 2 is slidably mounted on the handrail housing 1, that is, the handrail support 2 slides on the handrail housing 1 to adjust the front-to-back position and height of the handrail support 2. The slide rail assembly 3 is disposed between the handrail support 2 and the handrail housing 1, and includes: an outer slide rail 30 and an inner slide rail 31. The outer slide rail 30 is fixed to the handrail housing 1, and the inner slide rail 31 is fixed to the handrail support 2. The inner slide rail 31 is slidably mounted on the outer slide rail 30. When the handrail support 2 slides relative to the handrail housing 1, the inner slide rail 31 slides along the outer slide rail 30.

[0058] In this invention, the armrest support 2 can be slidably adjusted relative to the armrest housing 1. When the car seat is in various positions (such as the design position, zero-gravity position, or bed position), the armrest support 2 can be slidably adjusted to provide support for the passenger's elbows, ensuring that the armrest support 2 provides elbow support in any position, thus improving passenger comfort. The slide rail assembly 3 is disposed between the armrest support 2 and the armrest housing 1. The outer slide rail 30 is fixed to the armrest housing 1, and the inner slide rail 31 is fixed to the armrest support 2 and slidably disposed on the outer slide rail 30, enabling the armrest support 2 to be slidably adjusted on the armrest housing 1. When the armrest support 2 slides relative to the armrest housing 1, the inner slide rail 31 slides along the outer slide rail 30. The armrest support 2 slides smoothly and stably, providing a good user experience.

[0059] Furthermore, in this embodiment, the slide rail assembly 3 further includes multiple ball bearings 32, which are disposed between the outer slide rail 30 and the inner slide rail 31. The inner slide rail 31 has a through hole 310, through which the ball bearings 32 pass and abut against the outer slide rail 30. When the inner slide rail 31 slides relative to the outer slide rail 30, the multiple ball bearings 32 roll, thereby driving the armrest support 2 to slide on the armrest housing 1.

[0060] Specifically, the slide rail assembly 3 is symmetrically arranged between the handrail support 2 and the handrail housing 1, enabling synchronous movement of both sides of the handrail support 2. When the handrail support 2 moves relative to the handrail housing 1, the inner slide rail 31, which is fixedly connected to the handrail support 2, moves relative to the outer slide rail 30, which is fixed to the handrail housing 1. The inner slide rail 31 has multiple through holes 310 that can accommodate multiple balls 32. The balls 32 pass through the through holes 310 and abut against the inner wall of the outer slide rail 30, rolling between the outer slide rail 30 and the inner slide rail 31. At this time, the inner slide rail 31 moves relative to the outer slide rail 30, and the handrail support 2, which is fixedly connected to the inner slide rail 31, moves relative to the handrail housing 1.

[0061] Furthermore, the handrail box 1 is provided with a guide slope 10, and the handrail support 2 is provided with a sliding surface 20 that cooperates with the guide slope 10. The sliding surface 20 and the guide slope 10 are in sliding cooperation. When the handrail support 2 moves relative to the handrail box 1, the sliding surface 20 slides along the guide slope 10, and the position and height of the handrail support 2 on the handrail box 1 change.

[0062] In this invention, the armrest housing 1 is provided with a guide slope 10, and the armrest support 2 is provided with a sliding surface 20 that cooperates with the guide slope 10. The sliding surface 20 and the guide slope 10 slide in cooperation, which can ensure that the armrest support 2 is accurately positioned during movement, and the sliding process is smoother and more continuous. When the armrest support 2 moves relative to the armrest housing 1, the sliding surface 20 slides along the guide slope 10. The slope makes the armrest support 2 move continuously and gradually during movement, so as to realize the change of the position and height of the armrest support 2 on the armrest housing 1. Moreover, the sliding of the armrest support 2 on the armrest housing 1 can realize the fine adjustment of the position of the adjustable armrest.

[0063] Preferably, such as Figures 4-6 As shown, one end of the inner slide rail 31 is provided with a first limiting piece 311, and the other end of the inner slide rail 31 is provided with a second limiting piece 312. The inner slide rail 31, the first limiting piece 311, and the second limiting piece 312 are integrally formed. The first limiting piece 311 and the second limiting piece 312 are used to limit the displacement of the inner slide rail 31 along the outer slide rail 30. That is, when the inner slide rail 31 moves relative to the outer slide rail 30, the first limiting piece 311 limits the downward displacement of the handrail support 2 along the guide slope 10, and the second limiting piece 312 limits the upward displacement of the handrail support 2 along the guide slope 10, so as to prevent the handrail support 2 from derailing when it moves.

[0064] Furthermore, such as Figure 4 As shown, the adjustable handrail also includes a motor 4 and a lead screw 5. The motor 4 is mounted on the handrail housing 1, and the lead screw 5 is located at the output end of the motor 4. A nut structure 50 is provided on the handrail support 2, and the nut structure 50 is mounted on the lead screw 5, forming a lead screw 5-nut mechanism. That is, the output end of the motor 4 drives the lead screw 5 to rotate, and the handrail support 2 is connected to the nut structure 50. The rotation of the lead screw 5 pushes the nut structure 50 to move linearly along its axial direction. At this time, the nut structure 50 drives the handrail support 2 connected to it to move. The slide rail assembly 3 is inclined, and the setting direction of the lead screw 5 is parallel to that of the slide rail assembly 3 to achieve stable guidance.

[0065] Specifically, the armrest box 1 also includes a connecting seat 11, and the motor 4 and the lead screw 5 are all mounted on the connecting seat 11 to ensure that the drive and guide structure is compact and stable, and the outer slide rail 30 is fixed on the connecting seat 11 for easy installation.

[0066] The adjustable handrail also includes a table assembly 6, which is slidably disposed within the handrail housing 1. The table assembly 6 includes a table 60 and a push rod 61, with the table 60 connected to the push rod 61. The table 60 can slide retractably along the push rod 61. Specifically, the table assembly 6 is connected to a motor and is hidden inside the handrail housing 1 when not in use, maintaining a neat and tidy appearance. When needed, the motor 4 drives the table 60 to unfold and lock from the handrail housing 1 along the push rod 61. After use, the motor drives the table 60 to automatically retract into the handrail housing 1 along the push rod 61. The table 60 is adjustable in multiple directions to meet the needs of passengers in different positions.

[0067] The refrigerator (not shown in the figure) is located in the armrest box 1. It can store items, making high space utilization. When not in use, it is hidden inside the armrest box 1, combining practicality and aesthetics.

[0068] In this embodiment, the armrest support 2 slides on the armrest housing 1 to adjust its front-to-back position and height. The motor 4 drives the lead screw 5 to rotate, and the nut structure 50 is fixed to the armrest support 2. The nut structure 50 is mounted on the lead screw 5 and moves linearly along the axial direction of the lead screw 5, thereby causing the armrest support 2 to slide. When the armrest support 2 slides relative to the armrest housing 1, the inner ball bearing 32 of the slide rail assembly 3 slides between the outer slide rail 30 and the inner slide rail 31, and the inner slide rail 31 slides within the outer slide rail 30. This causes the sliding surface 20 of the armrest support 2 to slide along the guide ramp 10 of the armrest housing 1. The position and height of the armrest support 2 on the armrest housing 1 change to ensure that the user's elbows are supported in any position and posture while in the car seat, providing good comfort. During the sliding process of the handrail support 2, the first limiting piece 311 restricts the downward displacement of the handrail support 2 along the guide slope 10, and the second limiting piece 312 restricts the upward displacement of the handrail support 2 along the guide slope 10.

[0069] Example 2:

[0070] This embodiment relates to a car seat system, including: a first electric slide rail (not shown) and a second electric slide rail (not shown) arranged in parallel; a car seat (not shown) mounted on the first electric slide rail, wherein the first electric slide rail can drive the car seat; and an adjustable armrest as in Embodiment 1, wherein an armrest housing 1 is mounted on the second electric slide rail, and the second electric slide rail can drive the armrest housing 1. That is, the first electric slide rail drives the car seat to slide within the car to accommodate users of different sizes and improve comfort; the second electric slide rail drives the armrest housing 1 to slide within the car, ensuring elbow support for users of different sizes and improving comfort when driving or riding.

[0071] Specifically, the car seat system also includes a controller (not shown in the figure). The car seat has a zero-gravity mode, which adjusts the backrest and seat cushion to distribute the user's body pressure evenly, reducing spinal and muscle load and improving comfort. When the car seat switches from its designed position to zero-gravity mode, the controller controls the armrest support 2 to slide relative to the armrest housing 1, and controls the second electric slide rail to slide the armrest housing 1. That is, when the user adjusts the backrest alone, or switches the driving mode to zero-gravity mode, the backrest rotates at a certain angle, and the controller controls the second electric slide rail to move the armrest housing 1 to a designated position to match the adjusted position of the car seat. At the same time, the controller controls the armrest support 2 to move to a designated position and height on the armrest housing 1 to match the rotated position of the backrest, ensuring that the user's elbows are supported in different postures. The length of the second electric slide rail is longer than that of the first electric slide rail, which can meet the adjustable armrest adjustment within the entire range of the car seat's fore-and-aft travel.

[0072] In this invention, the car seat system includes a first and second electric slide rail arranged in parallel, a car seat, and a controller. The car seat has a zero-gravity mode. When the car seat switches from its designed position to zero-gravity mode, the controller controls the armrest support 2 to slide relative to the armrest box 1, and controls the second electric slide rail to make the armrest box 1 slide. That is, when the car seat is in zero-gravity mode, the backrest and seat cushion will rotate at a certain angle to reduce the user's body pressure. At this time, the controller controls the second electric slide rail to make the armrest box 1 slide, and its position can match the position of the car seat. At the same time, the controller controls the armrest support 2 to slide on the armrest box 1 to adjust the position and height of the armrest support 2 to ensure that the user's elbows are supported in various postures. Furthermore, the controller controls the second electric slide rail and the armrest support 2 to automatically adjust. The adjusted position and height of the armrest support 2 conform to ergonomics, providing high user comfort, and eliminating the need for manual adjustment by the user. The second electric slide rail is longer than the first electric slide rail, which can meet the adjustment of the adjustable armrests within the entire range of the car seat's forward and backward travel. That is, no matter where the car seat is moved, the adjustable armrests can slide to the side of the car seat to achieve full range adjustment.
