[0030] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0031] like Figures 1-4 As shown, a chair table in this embodiment includes a first table 1, a second table 2, and a keyboard 3; the first table 1 is connected to the seat back 5 via a hinge 4, the second table 2 and the first table 1 form an accommodating space, the second table 2 and the first table 1 are movably connected in an openable and closable manner, and the keyboard 3 is placed in the accommodating space.
[0032] The first table 1 is connected to the seat back 5 via a hinge 4, which is existing technology. The hinge 4 allows the first table 1 to rotate the entire seat table to a position that fits against the seat back 5, and the first table 1 is fixed at this angle by other fixing structures. At this time, the seat table is stored on the seat back 5 to prevent it from taking up space. The hinge 4 also allows the first table 1 to rotate the entire seat table to a horizontal angle parallel to the vehicle floor, at which time the seat table can be used to place items.
[0033] The second table 2 is movably connected to the first table 1 in an openable and closable manner. The opening and closing mechanism can be varied, such as flipping open or sliding open. When the entire seat table is rotated to a horizontal angle parallel to the vehicle floor, and the keyboard 3 is placed in the storage space, the seat table can be used as a regular table. For example, books, tablets, mobile phones, food, etc., can be placed on the upper surface of the second table 2. When the user needs to use the keyboard 3, one method is to open the second table 2 and use the keyboard 3 directly on the first table 1; another method is to open the second table 2, remove the keyboard 3, close the second table 2, and then place the keyboard 3 back on the second table 2 for use. The upper surfaces of both the first table 1 and the second table 2 can be provided with anti-slip patterns. The upper surface refers to the surface facing upwards when the seat table is at a horizontal angle parallel to the vehicle floor.
[0034] In this embodiment, the first tabletop 1 includes a first tabletop 1 body and two first connecting flanges 101, which are respectively disposed on opposite sides of the first tabletop 1 body; the second tabletop 2 includes a second tabletop 2 body and two second connecting flanges 201, which are respectively slidably engaged with the two first connecting flanges 101, and the accommodating space is formed between the first tabletop 1 body and the second tabletop 2 body.
[0035] The second tabletop 2 is movably connected to the first tabletop 1 in an openable and closable manner. In this embodiment, the openable and closable manner is selected by sliding opening. The first connecting flange 101 and the second connecting flange 201 slide together, which enables the second tabletop 2 and the first tabletop 1 to slide open.
[0036] In this embodiment, the two first connecting flanges 101 protrude from the main body of the first tabletop 1 in a direction close to the main body of the second tabletop 2, and the two second connecting flanges 201 protrude from the main body of the second tabletop 2 in a direction close to the main body of the first tabletop 1. Specifically, when the seat tabletop is at a horizontal angle parallel to the vehicle floor, the two first connecting flanges 101 protrude upward from the main body of the first tabletop 1, and the two second connecting flanges 201 protrude downward from the main body of the second tabletop 2.
[0037] Since the first connecting flange 101 and the second connecting flange 201 are protruding, a gap is formed between the main body of the second tabletop 2 and the main body of the first tabletop 1, thereby forming a space for placing the keyboard 3.
[0038] In this embodiment, the first tabletop 1 further includes a first limiting flange 102, which protrudes from the main body of the first tabletop 1 in a direction close to the main body of the second tabletop 2, and the first limiting flange 102 is disposed on the side of the first tabletop 1 close to the hinge 4; the second tabletop 2 is provided with a limiting abutment surface 202 for abutting against the first limiting flange 102.
[0039] Preferably, the left and right ends of the first limiting flange 102 are connected to the two first connecting flanges 101 respectively, forming a U-shaped enclosing protruding overall structure. The overall structure has higher strength and is not easily deformed, preventing the deformation of the two first connecting flanges 101 from affecting the smoothness and stability of the sliding of the second table board 2.
[0040] When the seat table is in contact with the seat back 5, the seat table is stored on the seat back 5, the keyboard 3 is located in the receiving space, and the first limiting flange 102 of the seat table at this angle is located below the keyboard 3, which can prevent the keyboard 3 from sliding out of the receiving space.
[0041] When the seat table is at a horizontal angle parallel to the vehicle floor, when the second table 2 slides to the position where its limiting contact surface 202 abuts against the first limiting flange 102, the second table 2 has moved into place, closing the accommodating space and hiding the keyboard 3 underneath. As the second table 2 gradually moves away from the first limiting flange 102 until the second table 2 slides off the first table 1 as a whole, the accommodating space of the second table 2 opens, revealing the keyboard 3. The keyboard 3 can then be used directly, or it can be removed and the second table 2 closed before being used on the second table 2.
[0042] In this embodiment, the first tabletop 1 further includes a locking groove 103, which is disposed on the side of the first tabletop 1 away from the hinge 4; the second tabletop 2 is provided with a locking member 203 for engaging with the locking groove 103.
[0043] When the second tabletop 2 slides to the position where its limiting contact surface 202 abuts against the first limiting flange 102, the locking member 203 engages with the locking slot 103 to lock the position of the second tabletop 2. When it is necessary to open the second tabletop 2, separating the locking member 203 from the locking slot 103 will release the position lock of the second tabletop 2, allowing the second tabletop 2 to slide.
[0044] In this embodiment, the keyboard 3 is a Bluetooth keyboard 3. The Bluetooth keyboard 3 can be used to connect to the Bluetooth system of the rear screen of the vehicle's smart cockpit or the user's own tablet or other electronic devices without the need for external wiring, making it more convenient to use.
[0045] In this embodiment, the keyboard 3 includes an MCU 301, a Bluetooth module 302, a button module 303, and a touchpad module 304. The Bluetooth module 302, the button module 303, and the touchpad module 304 are all communicatively connected to the MCU 301.
[0046] MCU301 is the microcontroller unit, which is the core control chip of keyboard 3, responsible for functions such as key scanning, data processing and communication.
[0047] The Bluetooth module 302 and the MCU 301 can communicate using UART, where UART stands for Universal Asynchronous Receiver Transmitter.
[0048] The keyboard module 3 and MCU301 can communicate using an AD converter, and the touchpad module 304 and MCU301 can communicate using an AD converter. Here, AD stands for Analog-to-Digital, which is analog signal conversion technology.
[0049] The MCU301 can feed back information from the button module 303 and the touchpad module 304 to the Bluetooth module 302, and then feed the information back to an external terminal via the Bluetooth module 302. The external terminal can be the rear screen of the vehicle's smart cockpit or a tablet or other electronic device brought by the user.
[0050] In this embodiment, the keyboard 3 further includes a power module 305 and a power management chip 306 for managing the power module 305. The power management chip 306 is communicatively connected to the MCU 301.
[0051] The power management chip 306 is the PMIC (Power Management Integrated Circuit), and the power module 305 is built into the keyboard 3, which can provide power to the keyboard 3. At the same time, the keyboard 3 can also be equipped with a Type-C power input interface 307, which is used for charging or connecting to an external power source.
[0052] A seat assembly in this embodiment includes a seat back 5 and the aforementioned seat table, wherein the first table 1 of the seat table is connected to the seat back 5 via a hinge 4.
