[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] For embodiments of this utility model, please refer to [link / reference]. Figures 1 to 4 The system includes a seat frame 9 and a slide rail 7. The seat frame 9 is slidably mounted on top of the slide rail 7. When adjusting the front and rear positions of the seat frame 9, the seat frame 9 slides on top of the slide rail 7. A seat cushion frame 5 is hinged to the top front side of the seat frame 9, and a backrest support arm 3 is hinged to the top rear side of the seat frame 9. A backrest frame 2 is hinged to the top of the backrest support arm 3. A seat adjustment switch 8 is provided on the side of the seat frame 9. A seat cushion angle adjuster 6 is provided at the hinge position between the seat cushion frame 5 and the seat frame 9. A downward angle adjuster 4 is provided at the hinge position between the backrest support arm 3 and the seat frame 9. An upward angle adjuster 1 is provided at the junction of the backrest frame 2 and the backrest support arm 3. The upper and lower angle adjusters 1, 4, and 6 are all driven by angle adjustment motors. The upper angle adjuster 1, 4, and 6 all use the TJX2 angle adjuster from Hubei Zhonghang Precision Machinery Technology Co., Ltd. This high-performance electric angle adjuster has a circular sheath structure as its core component platform, with no free travel during operation and no reversing noise. There is no gap in the backrest during adjustment. The angle adjustment motor uses a KEFON F110 brushed DC motor with a rated power of 30W and a rated voltage of 12V, which is suitable for adjusting the height and backrest of car seats. The angle adjustment motor is electrically connected to the seat adjustment switch 8 via a wire.

[0025] By setting up the seat cushion frame 5, the angle of the seat cushion frame 5 can be adjusted by the seat cushion angle adjuster 6, thereby adjusting the tilt angle of the seat cushion to accommodate the needs of different people. Furthermore, after the seat cushion frame 5 is fully opened upwards, the space inside the seat frame 9 can be exposed, making it convenient to use the space under the seat for storing items.

[0026] The width of the backrest frame 2 is smaller than the distance between the backrest arms 3 so that the backrest frame 2 can be stored between the backrest arms 3. The width of the seat cushion frame 5 is smaller than the distance between the seat frames 9 so that the seat cushion frame 5 can be stored inside the seat frame 9.

[0027] When adjusting the angle of the backrest arm 3, the seat adjustment switch 8 controls the adjustment motor on the lower adjustment device 4 to rotate the backrest arm 3. When unfolding the backrest frame 2, the seat adjustment switch 8 controls the adjustment motor on the upper adjustment device 1 to rotate the end of the backrest frame 2 backward. After rotating 180°, it forms the same plane as the backrest arm 3. When opening the seat cushion frame 5, the seat adjustment switch 8 controls the adjustment motor on the seat cushion adjustment device 6 to rotate the end of the seat cushion frame 5 upward and open the top of the seat frame 9.

[0028] By setting the backrest frame 2, the backrest frame 2 can be rotated and adjusted. After the backrest frame 2 is rotated backward and opened, the backrest can be extended. At the same time, after the backrest support arm 3 is adjusted to a horizontal state, the seat can be unfolded into a bed form, so as to facilitate the adjustment of the seat and allow the passengers to rest.

[0029] The bottoms of the two seat frames 9 are connected to each other by steel plates. A translation motor 11, which is electrically connected to the seat adjustment switch 8 via wires, is installed in the middle of the steel plates. The translation motor 11 is a KEFON F109 brushed DC motor with a rated power of 30W and a rated voltage of 12V, which is suitable for the horizontal adjustment of car seats. The output shaft of the translation motor 11 is powered to a rotating shaft 12. A gear is keyed to the end of the rotating shaft 12. A rack that meshes with the gear is provided on the bottom wall of the slide rail 7.

[0030] When translating the position of seat frame 9, such as Figure 4 As shown, the seat adjustment switch 8 controls the rotation of the translation motor 11, and the power is transmitted to the gear through the rotating shaft 12, so that the gear rolls on the rack, thereby translating the seat. After the position is adjusted, the power to the translation motor 11 is cut off, so that the translation motor 11 self-locks.

[0031] A tabletop 10 is placed inside the seat frame 9. Anti-slip magnets are installed at the four corners of the bottom of the tabletop 10. The anti-slip magnets are permanent magnets and are installed at the four corners of the bottom of the tabletop 10 to attract the iron metal surface at the bottom of the seat frame 9. The tabletop 10 is embedded inside the seat frame 9 and fits the seat frame 9 on all four sides. The attraction force of the anti-slip magnets needs to be greater than the weight of the tabletop 10 to increase the stability of the tabletop 10. When the car goes over bumpy roads, it can prevent the tabletop 10 from falling off. By setting the anti-slip magnets, the tabletop 10 can be firmly attracted to the bottom of the seat frame 9, and it is also easy to fix the tabletop 10 when it is removed.

[0032] By setting the table board 10, the bottom of the seat frame 9 can be closed. When it is necessary to unfold it into a table inside the vehicle, the table board 10 can be taken out from inside the seat frame 9 and placed on the seat cushion frame 5 to form a table, thus achieving the purpose of convenient table storage and use.

[0033] The specific usage steps and principles of this utility model are as follows:

[0034] First, the seat adjustment switch 8 controls three angle adjustment motors and one translation motor 11. The seat adjustment switch 8 is a two-way switch, which can be used with a Kangerle four-way lever switch. The four-way switch on the rear side controls the upper angle adjuster 1 and the lower angle adjuster 4, and the four-way switch on the front side controls the seat cushion angle adjuster 6 and the translation motor 11. When the seat needs to be adjusted into a bed, the passenger sits on the seat and turns the bottom of the four-way switch on the rear side of the seat adjustment switch 8 backward to activate the upper angle adjuster 1. The angle adjustment motor drives the upper angle adjuster 1 to rotate, thereby controlling the backrest frame 2 to rotate backward. After the backrest frame 2 rotates backward 180°, the backrest frame 2 and the backrest support arm 3 unfold to the same plane. Then, the top of the four-way switch on the rear side of the seat adjustment switch 8 is turned backward to flatten the backrest support arm 3 backward, thus adjusting the table and chair into a bed state.

[0035] By setting up the backrest frame 2, it can be stored inside the backrest support arm 3 when not in use. The side of the backrest support arm 3 closest to the human body is wrapped with imitation leather and inner foam padding to ensure good comfort. The back of the backrest support arm 3 has a groove for storing the backrest frame 2. When the backrest frame 2 is not in use, it does not affect the normal use of the table and chair. When the backrest frame 2 is in use, the linkage between the backrest support arm 3 and the backrest frame 2 can be used to adjust the table and chair to be more level and extend the entire backrest for convenient use.

[0036] When it is necessary to open the storage space inside the seat frame 9, first make sure that no one is sitting on the table and chair and there is nothing on it. Turn the rear end of the four-way switch on the front side of the seat adjustment switch 8 upward to open the seat cushion frame 5 upward, which will expose the storage space inside the seat frame 9. By setting the seat cushion frame 5, the angle of the seat cushion frame 5 can be adjusted by the seat cushion angle adjuster 6, thereby adjusting the tilt angle of the seat cushion to accommodate the needs of different people. After the seat cushion frame 5 is fully opened upward, the space inside the seat frame 9 can be exposed, so as to make it convenient to use the space under the seat to store items.

[0037] When the tabletop 10 is needed again, it can be taken out and attached to the seat frame 5 using anti-slip magnets. When not in use, since the tabletop 10 is embedded inside the seat frame 9, the four sides of the tabletop 10 fit the seat frame 9. The attraction force of the anti-slip magnets needs to be greater than the weight of the tabletop 10 to increase the stability of the tabletop 10. When the car goes over bumpy roads, it can prevent the tabletop 10 from falling off. By setting anti-slip magnets, the tabletop 10 can be firmly attached to the bottom of the seat frame 9, which can facilitate the storage and use of the table.

[0038] When adjusting the seat forward and backward, moving the four-way switch in front of the seat adjustment switch 8 forward and backward will cause the translation motor 11 to drive the rotating shaft 12 to rotate, and the seat will move horizontally on the slide rail 7 by using the cooperation of gears and racks.
