[0016] In summary, the present invention has the following beneficial effects:

[0017] 1. A first table storage component and a second table storage component are respectively installed in the armrests at both ends of the car seat. Both the first and second table storage components include a horizontal sliding storage component and a vertical sliding storage component. Furthermore, the first and second table components, which can be combined with each other, are respectively installed on the vertical sliding storage component based on the first and second rotating storage components. The combination of the first and second table components creates a single table on the seat, increasing the usable area of ​​the table and meeting the needs of passengers for dining and entertainment, thus improving comfort. The first and second table components are stored within the car seat armrests using the horizontal sliding storage component, vertical sliding storage component, first rotating storage component, and second rotating storage component, respectively, avoiding obstruction of seating space. The first and second tabletop assemblies each include a rotating plate rotatably connected to a vertical slider, and a storage plate is mounted on the rotating plate via a third rotating storage assembly. An adjustment groove is formed on the storage plate, and an adjustment plate is slidably connected within the groove based on the adjustment assembly. Passengers can control the position of the adjustment plate within the groove by pressing or pulling it, thus adapting to different user needs. Adjusting the angle of the storage plate relative to the rotating plate and the position of the adjustment plate within the groove further adapts to different user needs. For example, when the storage plate is parallel to the rotating plate and the adjustment plate is flush with the surface of the storage plate, it can meet the needs of passengers for eating and working. When the storage plate is tilted and the adjustment plate is recessed into the storage plate, passengers can place mobile phones, tablets, etc., on the adjustment plate to meet their entertainment needs, greatly improving user comfort. The structure is simple.

[0018] 2. Individual control buttons and a master control button are installed on the armrest of the car seat. For frequently used passengers, the positions of the first and second table panels can be set so that the master control button can be pressed directly when in use, which greatly improves the convenience of use. At the same time, the horizontal sliding storage component, the vertical sliding storage component, the first rotating storage component, the second rotating storage component, the first table panel, and the second table panel can be controlled by pressing the control buttons to adjust the position and angle of the storage board, so as to meet the needs of different users, making it convenient to adjust and improving the comfort of use.

[0019] 3. An electromagnetic coil is installed at the bottom of the adjustment slot and a metal plate is installed on the back of the adjustment plate. When the vehicle is under emergency braking or a car accident occurs, the electromagnetic coil is energized and repels the metal plate, thereby pushing the adjustment plate out of the adjustment slot. The human body comes into contact with the adjustment plate due to inertia, which plays a certain role in buffering. At the same time, when the vehicle is under emergency braking or a car accident occurs, the system instantly controls the third rotating storage component to adjust the angle of the storage plate so that the storage plate is as parallel as possible to the human body, so that the human body can come into contact with the adjustment plate at a parallel angle, thereby reducing the injury to the human body.

[0020] 4. A first rotating plate is stacked on top of a second rotating plate, with a support block on the first rotating plate. A support groove is provided on the second rotating plate to cooperate with the support block, ensuring the stability of the first rotating plate stacked on the second rotating plate and preventing wobbling of the first and second table assemblies during combined use, which would affect user comfort. Simultaneously, a first rotating storage assembly and a second rotating storage assembly are used to drive the first and second rotating plates to rotate respectively. The first rotating storage assembly uses a first storage screw to drive the first storage block to slide on a vertical slider, thereby driving the second storage block to slide on the first rotating plate, thus rotating the first rotating plate. This ensures the rotation speed of the first rotating plate while avoiding the first rotating storage assembly from occupying passenger legroom. The second rotating storage assembly uses a second storage motor to drive the third storage rod to rotate, which in turn drives the third storage rod to rotate, thus rotating the second rotating rod. Its strong support for the second rotating plate ensures the strength of the combined first and second table assemblies and guarantees structural stability. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Example:

[0031] refer to Figures 1 to 7A car seat armrest includes a symmetrically arranged car seat armrest base 1. A first tabletop storage component 2 and a second tabletop storage component 3 are symmetrically arranged within the car seat armrest base 1. Both the first tabletop storage component 2 and the second tabletop storage component 3 include a horizontally sliding storage component 4 slidably connected to the car seat armrest base 1 along a horizontal direction and a vertically sliding storage component 5 slidably connected to the horizontally sliding storage component 4 along a vertical direction. The horizontally sliding storage component 4 and the vertically sliding storage component 5 allow the first tabletop storage component 2 and the second tabletop storage component 3 to be stored within the car seat armrest base 1, thereby reducing space occupation. Simultaneously, because the car seat armrest base 1 has a larger volume, it can store a larger tabletop. Furthermore, the first tabletop storage component 2 and the second tabletop storage component 3 are rotatably connected to the vertically sliding storage component 5 based on a first rotating storage component 6 and a second rotating storage component 7, respectively, enabling mutual combination of a first tabletop component 8 and a second tabletop component 9.

[0032] refer to Figure 1 Specifically, the horizontal sliding storage assembly 4 includes several horizontal grooves 41 opened along the horizontal direction in the car seat armrest seat 1 and horizontal sliders 42 slidably connected in the horizontal grooves 41. A mounting seat 43 for installing the vertical sliding storage assembly 5 is fixedly connected to the horizontal slider 42. A horizontal drive screw 44 and a horizontal drive motor 45 that drives the horizontal drive screw 44 to rotate are rotatably connected in the car seat armrest seat 1. A horizontal screw hole 46 that cooperates with the horizontal drive screw 44 is opened in the horizontal slider 42. The horizontal drive motor 45 drives the horizontal drive screw 44 to rotate, thereby driving the horizontal slider 42 to slide in the horizontal grooves 41, thereby driving the mounting seat 43 to extend and retract from the car seat armrest seat 1. At the same time, the extension length of the mounting seat 43 can be controlled by controlling the horizontal drive motor 45 to adapt to the usage needs of different passengers.

[0033] refer to Figure 1Specifically, the vertical sliding storage assembly 5 includes several vertical grooves 51 formed along the vertical direction on the mounting base 43, and vertical sliders 52 slidably connected within the vertical grooves 51. The first tabletop assembly 8 and the second tabletop assembly 9 are rotatably connected to the top of the vertical sliders 52 based on the first rotating storage assembly 6 and the second rotating storage assembly 7, respectively. In the stored state, the first tabletop assembly 8 and the second tabletop assembly 9 are both arranged parallel to the sliding sliders to reduce storage space. A vertical drive screw 53 is rotatably connected to the mounting base 43 to drive the vertical sliders 52. The vertical drive motor 54, which drives the lead screw 53 to rotate, has a vertical lead screw hole 55 on the vertical slider 52 that cooperates with the vertical drive screw 53. When the mounting base 43 extends out of the car seat armrest seat 1, the vertical drive motor 54 drives the vertical drive screw 53 to rotate, thereby causing the vertical slider 52 to slide in the vertical slide groove 51, thereby driving the first table assembly 8 and the second table assembly 9 to rise. At the same time, the distance between the first table assembly 8 and the second table assembly 9 and the ground can be adjusted by controlling the vertical drive motor 54 to adapt to the usage needs of different passengers.

[0034] refer to Figures 1 to 3Specifically, both the first tabletop assembly 8 and the second tabletop assembly 9 include a first rotating plate 81 and a second rotating plate 82 rotatably connected to the top of the vertical slider 52 on one side. At the end of the first rotating plate 81 and the second rotating plate 82 near the seat, a first shelf 84 and a second shelf are respectively rotatably connected to a third rotating storage assembly 83. An adjustment groove 86 is provided on both the first shelf 84 and the second shelf. An adjustment plate 87 is slidably connected in the adjustment groove 86. A rotating shelf 88 for supporting items placed on the adjustment plate 87 is rotatably connected to the bottom of the adjustment plate 87. An adjustment assembly 89 for controlling the position of the adjustment plate 87 is provided in the adjustment groove 86. The adjusting assembly 89 includes several elastic telescopic rods 891 embedded and fixedly connected in the adjusting groove 86. The telescopic ends of the elastic telescopic rods 891 are fixedly connected to the back of the adjusting plate 87. The side wall of the adjusting plate 87 is evenly provided with several adjusting holes 892 along the thickness direction. Several sliding grooves 893 are provided on the groove wall of the adjusting groove 86. Adjusting blocks 894 are slidably connected in the sliding grooves 893, which cooperate with the adjusting holes 892 to lock the adjusting plate 87 into the adjusting groove 86. The adjusting blocks 894 have a circular structure. The adjusting blocks 894 and the sliding grooves 893 are connected to each other. A return spring 895 is fixedly connected between the adjusting plate 87 and the adjusting slot 86. When it is necessary to adjust the position of the adjusting plate 87 in the adjusting slot 86, the passenger can control the position of the adjusting plate 87 in the adjusting slot 86 by pressing or pulling the adjusting plate 87 to adapt to different usage needs. During the pressing or pulling process, the side wall of the adjusting plate 87 abuts against the adjusting block 894, thereby compressing the return spring 895. When the adjusting block 894 moves to the position of the adjusting hole 892, the return spring 895 returns and drives the adjusting block 894 into the adjusting hole 892, thereby achieving locking. The adjusting block 895 is provided. The circular structure of the 94 allows passengers to release the locking state of the adjustment plate 87 by pressing or pulling it with a certain amount of force. Both the first table panel assembly 8 and the second table panel assembly 9 include a rotating plate rotatably connected to the vertical slider 52, and a shelf is set on the rotating plate via a third rotating storage assembly 83. At the same time, an adjustment groove 86 is opened on the shelf, and an adjustment plate 87 is slidably connected to the adjustment assembly 89 within the adjustment groove 86. Passengers can control the position of the adjustment plate 87 within the adjustment groove 86 by pressing or pulling it, thereby adapting to different user needs. By adjusting the angle of the shelf relative to the rotating plate and the position of the adjustment plate 87 within the adjustment groove 86, different user needs can be met. For example, when the shelf is parallel to the rotating plate and the adjustment plate 87 is flush with the surface of the shelf, it can meet the needs of passengers for eating and working. When the shelf is tilted and the adjustment plate 87 is recessed into the shelf, passengers can place mobile phones, tablets, etc. on the adjustment plate 87 to meet their entertainment needs, greatly improving the comfort of use. The structure is simple.

[0035] refer to Figures 1 to 3Specifically, an electromagnetic coil 810 is fixedly connected to the bottom of the adjustment slot 86, and a metal plate 811 that cooperates with the electromagnetic coil 810 is fixedly provided on the back of the adjustment plate 87. The metal plate 811 is made of iron. The electromagnetic coil 810 is coupled with the vehicle's collision system. When the vehicle is under emergency braking or a car accident occurs, the electromagnetic coil 810 is energized and repels the metal plate 811, thereby pushing the adjustment plate 87 out of the adjustment slot 86. The human body contacts the adjustment plate 87 due to inertia, thus playing a certain buffering role. At the same time, when the vehicle is under emergency braking or a car accident occurs, the system instantly controls the third rotating storage component 83 to adjust the angle of the shelf so that the shelf is as parallel as possible to the human body, so that the human body can contact the adjustment plate 87 at a parallel angle, thereby reducing the injury to the human body.

[0036] refer to Figure 4 Specifically, the first rotating storage assembly 6 includes a storage groove 61 formed vertically on a vertical slider 52 and a first storage block 62 slidably connected within the storage groove 61. A first storage rod 63 is hinged to the first storage block 62. A second storage block 64 is slidably connected to the first rotating plate 81 in a direction parallel to the storage groove 61. The other end of the first storage rod 63 is hinged to the second storage block 64. A first storage lead screw 65 is rotatably connected to the vertical slider 52 in a vertical direction and is fixedly connected to the vertical slider. On the 52, a first storage motor 66 is used to drive the first storage lead screw 65. A first storage hole 67 that cooperates with the first storage lead screw 65 is opened on the first storage block 62. The first rotating storage assembly 6 uses the first storage lead screw 65 to drive the first storage block 62 to slide on the vertical slider 52, thereby driving the second storage block 64 to slide on the first rotating plate 81, thereby driving the first rotating plate 81 to rotate. While ensuring the rotation speed of the first rotating plate 81, the first rotating storage assembly 6 also avoids occupying the passenger's leg space.

[0037] refer to Figure 5 Specifically, the second rotating storage assembly 7 and the third rotating storage assembly 83 have the same structure. The second rotating storage assembly 7 includes a second storage rod 71 fixedly connected to the center of the second rotating plate 82 along a direction perpendicular to the second rotating plate 82. A second storage motor 72 is fixedly connected to the vertical slider 52 of the second tabletop storage assembly 3. A third storage rod 73 is fixedly connected to the rotation shaft of the second storage motor 72. The end of the third storage rod 73 away from the second storage motor 72 is hinged to the end of the second storage rod 71 away from the second rotating plate 82. The second rotating storage assembly 7 drives the third storage rod 73 to rotate through the second storage motor 72, thereby pushing the third storage rod 73 to drive the second rotating rod to rotate. Its strong support force on the second rotating plate 82 ensures the strength of the combination of the first tabletop assembly 8 and the second tabletop assembly 9, and ensures the stability of the structure.

[0038] refer to Figure 6 Specifically, the first rotating plate 81 and the second rotating plate 82 are stacked on top of each other, with the first rotating plate 81 stacked on top of the second rotating plate 82. A support block 812 is fixedly provided on the end of the first rotating plate 81 away from the car seat armrest 1. A support groove 813 is provided on the second rotating plate 82 to cooperate with the support block 812, thereby ensuring the stability of the first rotating plate 81 stacked on the second rotating plate 82 and preventing the first table assembly 8 and the second table assembly 9 from shaking when used together, which would affect the comfort of use. At the same time, the first rotating storage assembly 6 and the second rotating storage assembly 7 are used to drive the first rotating plate 81 and the second rotating plate 82 to rotate respectively. This avoids occupying leg space and also ensures the support of the second rotating plate 82 on the first support plate, thus ensuring the stability of the structure.

[0039] refer to Figure 7 Specifically, a wireless charging module 11 and a cup holder 12 are fixedly installed on the armrest seat 1 of the car seat. The armrest of the car seat is equipped with several control buttons 13 for controlling the horizontal sliding storage component 4, the vertical sliding storage component 5, the first rotating storage component 6, the second rotating storage component 7, the first table board component 8, and the second table board component 9, so as to achieve individual control. At the same time, a master control button 14 is also provided to achieve control according to the settings. For frequently used passengers, the positions of the first table board component 8 and the second table board component 9 can be set so that the master control button 14 can be pressed directly when in use, which greatly improves the convenience of use. At the same time, the horizontal sliding storage component 4, the vertical sliding storage component 5, the first rotating storage component 6, the second rotating storage component 7, the first table board component 8, and the second table board component 9 can be controlled by pressing the control buttons 13, so as to adjust the position and angle of the storage board, etc., to meet the needs of different users, making adjustment convenient and improving the comfort of use.

[0040] Brief description of usage: When in use, the horizontal sliding storage component 4, the vertical sliding storage component 5, the first rotating storage component 6, and the second rotating storage component 7 work to output the first table board component 8 and the second table board component 9 from the car seat armrest 1 and lift them to a certain height and unfold them, so that the first table board component 8 is stacked on the second table board component 9. At this time, passengers can adjust the angle of the storage board relative to the rotating board and the position of the adjustment plate 87 in the adjustment slot 86 to meet different usage needs. For example, when the storage board is parallel to the rotating board and the adjustment plate 87 is flush with the surface of the storage board, it can meet the needs of passengers for eating, working, etc. When the storage board is tilted and the adjustment plate 87 is recessed into the storage board, passengers can place mobile phones, tablets, etc. on the adjustment plate 87 to meet the entertainment needs of passengers.
