Description

Technical Field

[0001] This invention relates to a vehicle accessory, and more particularly to a seat armrest. Background Technology

[0002] With the rapid development of automotive technology and the rapid growth of car ownership, consumers' demand for cars has gradually evolved from simple transportation to a pursuit of functionality, comfort, and technological sophistication. This is especially true for SUVs and some business-oriented MPVs, where consumers may need to conduct various activities such as working, dining, and leisure activities during their journeys.

[0003] Therefore, seats with integrated table functions and touchscreen controls for seat and vehicle functions are highly sought after by consumers. Currently, seats offering tables generally fall into three categories:

[0004] The small tables integrated into the back of the front seats fold down for use by second-row passengers. However, these tables are located far from the second-row passengers, resulting in poor usability and comfort. Furthermore, because the tables are fixed to the front seat back when folded down, they increase the seat thickness and reduce second-row space.

[0005] The side-folding tables integrated into the inner armrests of the second-row seats mostly use vertical sliding rails. They need to be pulled vertically upwards and then folded inwards to unfold. These tables are small, impractical, low in height, and inconvenient. Many tables require the armrest to be lowered to cover them after unfolding, meaning the table height must be lower than the armrest height, making them too low and very inconvenient to use.

[0006] Therefore, it is desirable to provide a seat armrest that integrates a table and a touch screen to overcome the aforementioned technical deficiencies. Summary of the Invention

[0007] The purpose of this invention is to provide a seat armrest that integrates a table and a touch screen, which can provide customers with a foldable and retractable table that is comfortable to use, and at the same time provide a highly integrated, technologically advanced and easy-to-operate touch screen, thereby improving the riding experience in all aspects.

[0008] To achieve the above objectives, the present invention proposes a chair armrest integrating a table and a touch screen, comprising:

[0009] The lower part of the handrail has a cavity inside;

[0010] A folding tabletop assembly is disposed within the accommodating cavity, and the folding tabletop assembly includes a micro switch trigger.

[0011] The upper body of the handrail is rotatably connected to the lower body of the handrail via a pivot mechanism;

[0012] A touch screen assembly is disposed on the main body of the armrest. The touch screen assembly includes a touch screen, a touch screen transmission mechanism connected to the touch screen, and a motor connected to the touch screen transmission mechanism. The motor can control the touch screen transmission mechanism to drive the touch screen to extend or retract from the main body of the armrest.

[0013] The unlocking mechanism is connected to the upper body of the armrest and the lower body of the armrest, respectively.

[0014] A micro switch, which is connected to the motor;

[0015] In the unlocking position, the upper body of the armrest can rotate relative to the lower body of the armrest through the rotating shaft mechanism to open relative to the lower body of the armrest. In this state, the folding table assembly can extend out of the accommodating cavity. When the folding table assembly extends to the point that the micro switch trigger on it triggers the micro switch, the micro switch controls the motor to cause the touch screen transmission mechanism to drive the touch screen to retract.

[0016] Furthermore, in the armrest of the seat integrating a table and a touch screen described in this invention, the unlocking mechanism includes:

[0017] The unlock button is located on the main body of the armrest.

[0018] The locking rod has its head end connected to the unlocking button and its tail end in a hemispherical shape.

[0019] The locking hook is provided with a locking bar groove, a locking hook pivot, a hook, and a wedge-shaped body; wherein, in the locking position, the hook is hooked together with the lower body of the handrail;

[0020] When the unlock button is pressed, the unlock button pushes the locking rod to move linearly toward the locking hook, so that the tail end of the locking rod slides along the locking rod groove and pushes the wedge, so that the locking hook rotates around the locking hook pivot, so that the unlocking mechanism is in the unlocking position where the hook is disengaged from the lower body of the handrail.

[0021] Furthermore, in the armrest of the chair integrating a table and a touch screen described in this invention, the unlocking mechanism also includes a spring, which is configured to apply a preload to the unlock button so that when the external force pressing the unlock button is removed, the unlock button and the locking lever move linearly to reset the unlocking mechanism to the locked position.

[0022] Furthermore, in the armrest of the seat integrating a table and a touch screen described in this invention, the pivot mechanism includes:

[0023] The handrail pivot is fixedly installed relative to the lower body of the handrail;

[0024] A rotating arm, which is connected to the main body of the armrest;

[0025] A power-assisting spring, sleeved on the armrest pivot, applies a force to the rotating arm to rotate it about the armrest pivot.

[0026] Furthermore, the rotating shaft mechanism also includes an arc-shaped damping rack disposed on the rotating arm, the damping rack engaging with a damping gear disposed on the lower body of the handrail.

[0027] Furthermore, in the chair armrest integrating a table and a touch screen described in this invention, the touch screen assembly further includes:

[0028] A touch screen base is mounted on the armrest body, a motor is mounted on the touch screen base, a guide rail is provided on the touch screen base, the front end of the guide rail has an arc-shaped raised part, and the motor can drive the touch screen transmission mechanism to make the touch screen slide along the guide rail.

[0029] Furthermore, in the armrest of the seat integrating a table and a touch screen described in this invention, the touch screen transmission mechanism includes:

[0030] A lead screw, which is connected to the motor;

[0031] A slider is provided with a lead screw nut, which is connected to the lead screw through the lead screw nut so as to slide linearly relative to the touch screen base under the drive of a motor. The slider is hinged to the touch screen.

[0032] Support component, which is hinged to the touch screen;

[0033] A support connecting block is hinged to the support member and is slidable relative to the touch screen base.

[0034] Furthermore, in the seat armrest integrating a table and a touch screen described in this invention, the folding table assembly includes:

[0035] The folding tabletop pivot is located within the accommodating cavity, and the axial direction of the folding tabletop pivot is consistent with the thickness direction of the lower body of the armrest.

[0036] A vertical support arm is connected to the pivot of the folding table and can rotate around it. The micro switch trigger is located on the vertical support arm. A pin is provided on the vertical support arm, and the axial direction of the pin is consistent with the length direction of the lower body of the armrest.

[0037] An inclined support arm, which is hinged to a vertical support arm via the pin;

[0038] A connecting block, one end of which is hinged to an inclined support arm;

[0039] A horizontal support plate is hinged to the other end of the connecting block; the horizontal support plate is provided with a slide rail.

[0040] The rear plate is slidably connected to the horizontal support plate via the slide rail;

[0041] The front panel is hinged to the rear panel so that it can be opened relative to the rear panel in the longitudinal direction of the lower body of the armrest.

[0042] Furthermore, in the seat armrest integrating a table and a touch screen described in this invention, the folding table assembly further includes a horizontal limiting block disposed at the end of the horizontal support plate.

[0043] Furthermore, the chair armrest integrating a table and a touch screen according to the present invention also includes a pneumatic strut, which is disposed on the lower body of the armrest to apply a force to the folding table assembly to push it out of the receiving cavity.

[0044] The chair armrest integrating a table and a touch screen described in this invention has the following beneficial effects:

[0045] The seat armrest described in this invention, while incorporating a folding table and a touch screen, greatly saves seat space and improves customer comfort and ease of use of various functions.

[0046] The armrest of the seat of the present invention integrates a folding table and a retractable touch screen. The folding table is lifted upward by rotating the axis and folded and stretched towards the center of the seat when in use. The table has a large area and a suitable height, making it convenient to use.

[0047] The folding table and touch screen described in this invention are integrated into the seat armrest, so they can move back and forth with the seat body, maintaining a suitable relative distance from the passenger on the seat.

[0048] The foldable tabletop included in the armrest of the chair described in this invention can be hidden in the lower cavity of the armrest when folded up, without affecting the appearance of the armrest.

[0049] The seat armrest described in this invention includes a retractable touch screen. When the touch screen is retracted in a horizontal state, it overlaps with the surface of the armrest, resulting in an aesthetically pleasing design without affecting the lateral passage of the front of the armrest. When the touch screen is extended, it forms a certain angle with the surface of the armrest, providing better visibility and operability.

[0050] The folding table and touch screen in the armrest of the seat described in this invention are interconnected. When the touch screen is extended, unlocking the armrest and taking out the table triggers a micro switch, causing the screen to automatically retract as the armrest rotates backward, thus preventing interference between the front of the touch screen and the table support arm when the armrest is lowered after the table is unfolded.

[0051] In a preferred embodiment of the present invention, the armrest of the seat described herein, through the design of an unlocking mechanism, a damping gear, and a booster spring, allows the armrest to unlock when the customer needs to use the table by pressing the unlock button. With the help of the booster spring, the armrest will open upwards to move an angle, making it easier for the passenger to take out the folded table. Due to the reaction force of the damping gear, the whole process is carried out slowly, avoiding excessive elasticity when the armrest opens, which could impact the passenger's arm.

[0052] In a preferred embodiment of the present invention, when a customer needs to use the tabletop, the pneumatic strut will push the folding tabletop upward while opening the armrest, so that the lifting handle of the tabletop is exposed in the armrest cavity, making it convenient for the customer to take out the tabletop in a narrow space.

[0088] The following description, in conjunction with the accompanying drawings and specific embodiments, will further explain and illustrate the chair armrest integrating a table and a touch screen according to the present invention. However, this explanation and description do not constitute an undue limitation on the technical solution of the present invention.

[0089] Figure 1 The diagram shows the overall structure of the chair armrest integrating a table and a touch screen according to one embodiment of the present invention.

[0090] like Figure 1 As shown, in this embodiment, the armrest includes: a lower armrest body 1, a folding table assembly 2, an upper armrest body 3, and a touch screen assembly 5. Figure 1 In the state shown, the upper armrest body 3 is open relative to the lower armrest body 1, allowing the folding table assembly 2 to be removed and opened from the lower armrest body 1, and the touch screen assembly 5 is mounted on the upper armrest body 3.

[0091] Figure 2 The image shows the overall structure of the armrest body with a pivot mechanism installed in one embodiment of the chair armrest integrating a table and a touch screen according to the present invention. Figure 3 The image shows the upper body of the armrest of the chair armrest integrating a table and a touch screen according to one embodiment of the present invention, without the installation of a pivot mechanism.

[0092] Figure 4 The image shows the overall structure of the lower body of the chair armrest integrating a table and a touch screen, according to one embodiment of the present invention. From Figure 3 As can be seen, the lower body 1 of the armrest has a receiving cavity, which is used to accommodate the folding table assembly in the retracted state.

[0093] In this invention, the upper armrest body 3 can be opened or closed relative to the lower armrest body. An unlocking mechanism is used to lock or unlock the opening function.

[0094] Figure 5The diagram shows a schematic representation of the unlocking mechanism of the seat armrest integrating a table and a touch screen according to one embodiment of the present invention.

[0095] Figure 6 The diagram shows a split structure of the unlocking mechanism of the seat armrest integrating a table and a touch screen according to one embodiment of the present invention.

[0097] Figure 8 The unlocking mechanism is displayed in the unlocked state. Figure 2 A schematic diagram of the cross-section at point AA.

[0098] Figure 9 Showing Figure 2 A schematic diagram of the cross-section at point BB.

[0099] like Figure 5 and Figure 6 As shown, in one embodiment, the unlocking mechanism 4 includes: an unlocking button 41, a locking rod 42, a locking hook 43, a spring 44, and a fixing bracket 45. The locking rod 42 is connected to the unlocking button 41 by a protrusion 422 at its head engaging with a groove 411 in the unlocking button 41. The tail end of the locking rod 42 is hemispherical 421. The locking hook 43 is provided with a locking rod groove 431, a locking hook pivot 432, a hook 433, and a wedge 434 (see [reference]). Figure 7 and Figure 8 The fixed bracket 45 has a shaft hole 451 for mounting the lock hook pivot 432. The spring 44 is configured to apply a preload to the unlock button 41 so that when the external force pressing the unlock button 41 is removed, the unlock button 41 and the locking lever 42 can move linearly to the left under the spring force (see [link]). Figure 7 and Figure 8 ), so that the unlocking mechanism is reset to such a state. Figure 7 The locked workstation is shown.

[0100] like Figure 7 and Figure 9 As shown, in the locked position, the hook 433 of the locking hook 43 is hooked together with the lower body 1 of the handrail.

[0101] like Figure 8 and Figure 9As shown, when the unlock button 41 is pressed, the unlock button 41 pushes the locking rod 42 to move toward the locking hook 43 in a linear direction, so that the tail end of the locking rod 42 slides along the locking rod groove 431 and pushes the wedge 434. In this way, the locking hook 43 rotates around the locking hook pivot 432 as the rotation center, so that the unlocking mechanism 4 is in the unlocking position where the hook 433 is disengaged from the lower body 1 of the handrail.

[0102] In this invention, the upper armrest body 3 and the lower armrest body 1 are connected by a pivot mechanism 6, so that the upper armrest body 3 can be opened or closed relative to the lower armrest body 1. Figure 10 The diagram shows a schematic representation of the pivot mechanism of the chair armrest integrating a table and a touch screen according to one embodiment of the present invention.

[0103] Figure 11 The diagram shows a split structure of the pivot mechanism of the chair armrest integrating a table and a touch screen according to one embodiment of the present invention.

[0104] like Figure 11 As shown, in one embodiment, the pivot mechanism 6 includes: a handrail pivot 61 connected to the lower handrail body 1; a rotating arm 62 connected to the upper handrail body 3; a booster spring 63 sleeved on the handrail pivot 61 to apply a force to the rotating arm 62 to rotate it around the handrail pivot 61; and an arc-shaped damping rack 64 disposed on the rotating arm 62, the damping rack 64 engaging with a damping gear disposed on the lower handrail body 1.

[0105] Figure 12 The diagram shows a structural schematic of the touch screen assembly in one embodiment of the chair armrest integrating a table and a touch screen according to the present invention.

[0106] Figure 13 The diagram shows a schematic of the touch screen in the extended and raised state of the touch screen assembly of the chair armrest integrating a table and a touch screen according to one embodiment of the present invention.

[0107] Figure 14 The diagram shows a split structure of the touch screen assembly in one embodiment of the chair armrest integrating a table and a touch screen according to the present invention.

[0108] like Figure 14 As shown, in one embodiment, the touch screen assembly 5 includes: a touch screen 53; a touch screen base 51, which is disposed on the armrest body 3; a motor 52 disposed on the touch screen base 51; a guide rail 511 is provided on the touch screen base 51, and the front end of the guide rail 511 has an arc-shaped raised portion 5111 (see...). Figure 15 and 16The components include: a lead screw 54 connected to a motor 52; a slider 55 with a lead screw nut 551 connected to the lead screw 54, allowing it to slide linearly relative to the touch screen base 51 under the drive of the motor 52; the slider 55 hinged to the touch screen 53 via an axis at its end; a support member 56 hinged to the touch screen 53 via an axis at its end; and a support connecting block 57 hinged to the support member 56 and capable of sliding relative to the touch screen base 51.

[0109] Figure 15 The corresponding action of the touchscreen component in the retracted state is displayed. Figure 12 The cross-sectional view at point AA.

[0110] Figure 16 The display shows the corresponding action of the touchscreen component in the extended / raised state. Figure 12 The cross-sectional view at point AA.

[0111] like Figure 15 and Figure 16 As shown, during the extension of the touch screen 53, pressing the touch screen control button 58 causes the motor 52 to drive the slider 55 to slide linearly via the lead screw 54, thereby causing the touch screen 53, which is hinged to the slider 55, to slide along the guide rail 511. The touch screen 53 then drives the support member 56 (such as...) that is hinged to it. Figure 16 As shown, it stands upright, providing support for the touchscreen 53. During this process, the support connecting block 57 also slides horizontally under the influence of the support member 56. Figure 12 and Figure 15 As shown, the original state of touchscreen 53 is a horizontally retracted state to save space and increase aesthetics. Figure 13 and Figure 16 As shown, when the touch screen 53 slides out and rises, it provides passengers with a better field of vision for operating the touch screen, greatly improving the convenience and accuracy of operation.

[0112] The present invention also includes a micro switch 7 (e.g., for controlling the motor 52) Figure 17 As shown), this allows the extension and retraction of the touch screen to be linked to the movement of the folding table assembly 2. Specifically, when the folding table assembly 2 extends from the accommodating cavity to the point that the micro switch trigger on it actuates the micro switch 7, the micro switch 7 controls the motor 52 to retract the touch screen 53.

[0113] Figure 18 The image shows a folding table assembly of the seat armrest integrating a table and a touch screen, as described in one embodiment of the present invention, in its folded and retracted state.

[0114] Figure 19The image shows the folding table assembly of the chair armrest integrating a table and a touch screen according to one embodiment of the present invention in the open state.

[0115] Figure 20 The diagram shows a split structure of the folding table assembly of the seat armrest integrating a table and a touch screen according to one embodiment of the present invention.

[0116] Figure 21 It shows the tabletop not having slid out.

[0117] Figure 22 It shows the state of the tabletop sliding out.

[0118] like Figures 18 to 22 As shown, in one embodiment, the folding table assembly 2 includes: a folding table pivot 21 fixedly disposed within a receiving cavity, the axial direction of which is aligned with the thickness direction of the lower armrest body; a vertical support arm 22 connected to the folding table pivot 21 and capable of rotating around it; a micro switch trigger 222 disposed on the vertical support arm 22; a pin 221 disposed on the vertical support arm 22, the axial direction of which is aligned with the length direction of the lower armrest body 1 (i.e., the length direction of the vehicle); an oblique support arm 23 hinged to the vertical support arm 22 via the pin 221; and a connecting block 24 hinged at one end to the oblique support arm 23 and at the other end to the horizontal support plate 25. The rear plate 27 is slidably connected to the horizontal support plate 25 via a slide rail 28 provided on the horizontal support plate 25; the front plate 26 is hinged to the rear plate 27 via a hinge 211, so that the front plate 26 and the rear plate 27 can open relative to each other in the length direction of the lower body of the handrail; the horizontal limiting block 29 is also provided on the horizontal support plate 25 to limit the sliding stroke of the rear plate 27 in the horizontal direction.

[0119] Preferably, the horizontal support plate 25 is provided with a handle 251 to facilitate pulling out the folding table.

[0120] In this embodiment, the tabletop is divided into a front panel and a rear panel, which allows it to save space when folded. In addition, the folding tabletop assembly 2 may also include another damping gear 212 disposed on the horizontal support plate to prevent the rear panel from sliding freely in the horizontal direction.

[0121] In addition, the tabletop folding assembly may also include front and rear limit blocks 210, which are mounted on the vertical support arm 22 and abut against the armrest body after the tabletop is opened to prevent the tabletop from rotating.

[0122] In one embodiment of the present invention, such as Figure 24 As shown, the armrest frame 11 of the lower body 1 is also provided with a pneumatic strut 8, which is used to apply a force to the folding table assembly to push it out of the receiving cavity 12.

[0123] Figure 25 The illustration schematically shows the microswitch settings in one embodiment of the chair armrest integrating a table and a touch screen according to the present invention.

[0124] Figure 26 for Figure 25 A magnified view of a section at point C.

[0125] like Figure 25 and Figure 26 As shown, in one embodiment, a microswitch mounting slot P is installed on the armrest frame 11 of the lower armrest body by bolt Q, and the microswitch 7 is disposed therein. When the folding table assembly 2 rotates around the folding table pivot 21 until the microswitch trigger 222 no longer presses the spring plate 71 of the microswitch, the microswitch 7 is triggered, controlling the motor 52 to retract the touch screen 53.

[0126] The chair armrest integrating a table and a touch screen described in this invention can be operated according to the following steps:

[0127] 1. Operating the touchscreen: Pressing the touchscreen control button 58 causes the touchscreen 53 to automatically extend forward a set distance, such as 56mm, driven by the motor 52, and rise at a set angle relative to the horizontal plane, such as 24°. Figure 27 As shown. Sliding the screen out increases the touch area, and the increased angle provides a better viewing angle and easier operation. Pressing the touchscreen control button 58 again will automatically retract the screen back to its horizontal position, driven by the motor.

[0128] 2. Open the armrest: Press the unlock button 41 to unlock the upper body of the armrest; the upper body 3 of the armrest slowly and automatically opens to a certain angle, such as 30°, with the help of damping gears, damping racks and assist springs; at the same time as the upper body of the armrest opens, the pneumatic support rod 8 will push the folding table upwards a certain distance, such as 70mm, so that the folding table rotates around the folding table pivot 21 by a certain angle, such as 15°, so that the handle 251 of the folding table is exposed in the receiving cavity 12, making it easy to take out the folding table. Figure 28 As shown.

[0129] When the folding tabletop rotates to a set angle, such as 15°, the microswitch trigger 222 on the vertical support arm 22 triggers the microswitch 7. Figure 29 The contact state shown becomes Figure 30 When the armrest is released, the touch screen 53 retracts to prevent interference between the touch screen and the open tabletop after the armrest is lowered.

[0130] Manually continue opening the armrest body 3 to 90°. At this point, the touch screen 53 is fully retracted, and the tabletop rotates to a certain angle, such as 15°, to facilitate its removal. Figure 31 As shown.

[0131] 3. Open the folding tabletop: Manually rotate the folding tabletop to a vertical position using handle 251, as shown in Figure 32.
