Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] For an embodiment of the present invention, please refer to Figures 1 to 4 , including a seat frame 9 and a slide rail 7, the seat frame 9 is slidably mounted on the top of the slide rail 7, when the front and rear position of the seat frame 9 is adjusted, the seat frame 9 slides on the top of the slide rail 7, the front top of the seat frame 9 is hinged with a seat cushion frame 5, the rear top of the seat frame 9 is hinged with a backrest arm 3, the top of the backrest arm 3 is hinged with a backrest frame 2, a seat adjustment switch 8 is provided on the side of the seat frame 9, a seat cushion recliner 6 is provided at the position where the seat cushion frame 5 and the seat frame 9 are hinged, a lower recliner 4 is provided at the position where the backrest arm 3 and the seat frame 9 are hinged, an upper recliner 1 is provided at the intersection of the backrest frame 2 and the backrest arm 3, and an upper recliner The angle adjuster 1, the lower angle adjuster 4, and the seat cushion angle adjuster 6 are all driven by the angle adjustment motor. The upper angle adjuster 1, the lower angle adjuster 4, and the seat cushion angle adjuster 6 all use the TJX2 angle adjuster of Hubei AVIC Precision Machinery Technology Co., Ltd. This high-performance electric angle adjuster core component platform has a circular sheath structure, no operating idle stroke, no commutation sound, and no gap in the backrest during adjustment. The angle adjustment motor uses a KEFON brand F110 brushed DC motor with a rated power of 30W and a rated voltage of 12V. It is suitable for height adjustment and backrest adjustment of car seats. The angle adjustment motor is electrically connected to the seat adjustment switch 8 through a wire.

[0019] By setting up the seat cushion frame 5, the angle of the seat cushion frame 5 can be adjusted through the seat cushion adjuster 6, so that the inclination angle of the seat cushion can be adjusted to meet the needs of different people, and after the seat cushion frame 5 is fully opened upward, the space inside the seat frame 9 can be exposed, so as to facilitate the use of the space under the seat for storing items.

[0020] 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.

[0021] When adjusting the angle of the backrest arm 3, the seat adjustment switch 8 is used to control the angle adjustment motor on the lower recliner 4 to rotate the backrest arm 3. When unfolding the backrest frame 2, the seat adjustment switch 8 is used to control the angle adjustment motor on the upper recliner 1 to rotate the end of the backrest frame 2 backward. After rotating 180°, it forms the same plane with the backrest arm 3. When opening the seat cushion frame 5, the seat adjustment switch 8 is used to control the angle adjustment motor on the seat cushion recliner 6 to rotate the end of the seat cushion frame 5 upward to open the top of the seat frame 9.

[0022] By setting up a 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, thereby facilitating the adjustment of the seat so that the passengers can rest.

[0023] The bottoms of the left and right seat frames 9 are connected to each other through a steel plate. A translation motor 11 is installed in the middle of the steel plate and is electrically connected to the seat adjustment switch 8 through a wire. The model of the translation motor 11 is a KEFON brand F109 brushed DC motor with a rated power of 30W and a rated voltage of 12V, which is suitable for horizontal adjustment of car seats. The output shaft power of the translation motor 11 is connected to the rotating shaft 12, and the end key of the rotating shaft 12 is connected to a gear. The bottom wall of the slide rail 7 is provided with a rack that cooperates with the gear.

[0024] When the position of the seat frame 9 is translated, Figure 4 As shown, the seat adjustment switch 8 is used to control 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 of the translation motor 11 is cut off to make the translation motor 11 self-locking.

[0025] A table top 10 is placed inside the seat frame 9. Anti-slip magnets are set at the four corners of the bottom of the table top 10. The anti-slip magnets are permanent magnets and are installed at the four corners of the bottom of the table top 10. They are used to adsorb on the iron metal surface at the bottom of the seat frame 9. The table top 10 is embedded inside the seat frame 9, and the four sides of the table top 10 fit with the seat frame 9. The adsorption force of the anti-slip magnet needs to be greater than the gravity of the table top 10 to increase the stability of the table top 10. When the car passes through bumpy roads, it can prevent the table top 10 from falling off. By setting anti-slip magnets, the table top 10 can be firmly adsorbed on the bottom of the seat frame 9, and when the table top 10 is taken out, it can also be convenient to fix the table top 10.

[0026] By providing the table top 10, the bottom of the seat frame 9 can be closed. Moreover, when it is necessary to unfold it into a table in the car, the table top 10 can be taken out from the inside of the seat frame 9 and placed on the seat cushion frame 5 to form a table, thereby achieving the purpose of convenient storage and use of the table.

[0027] The specific steps and principles of the present invention are as follows: First, the seat adjustment switch 8 controls three angle adjustment motors and a translation motor 11. The seat adjustment switch 8 is two four-way switches, and a Kangerle four-way square lever switch can be used. 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 cushion angle adjuster 6 and the translation motor 11. When the seat needs to be adjusted to a bed, the passenger sits on the seat and rotates the bottom of the four-way switch on the rear side of the seat adjustment switch 8 backward to make the upper angle adjuster 1 work, and uses the angle adjustment motor to drive 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 arm 3 are unfolded in the same plane. Then, the top of the four-way switch on the rear side of the seat adjustment switch 8 is rotated backward to make the backrest arm 3 flat backward, and the table and chair can be adjusted to the state of a bed; By providing the backrest frame 2, it can be stored inside the backrest arm 3 when not in use, and the side of the backrest arm 3 close to the human body is wrapped with anti-genuine leather and filled with sponge to ensure good comfort. The back side of the backrest arm 3 is 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 arm 3 and the backrest frame 2 is utilized to adjust the table and chair to be more flat, and the entire backrest can be extended, achieving the purpose of convenient use. When it is necessary to open the storage space inside the seat frame 9, first ensure that no one is sitting on the table and chair, and do not put anything on it. Then, 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, so that the storage space inside the seat frame 9 can be exposed. By providing the seat cushion frame 5, the angle of the seat cushion frame 5 can be adjusted by the seat cushion adjuster 6, so that the inclination angle of the seat cushion can be adjusted to meet 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 that the space under the seat can be used to store items. When the table top 10 is needed again, the table top 10 can be taken out and adsorbed on the seat frame 5 using the anti-slip magnet. When not in use, since the table top 10 is embedded in the seat frame 9, the four sides of the table top 10 fit with the seat frame 9. The adsorption force of the anti-slip magnet needs to be greater than the gravity of the table top 10, thereby increasing the stability of the table top 10. When the car passes through bumpy roads, the table top 10 can be prevented from falling off. By providing the anti-slip magnet, the table top 10 can be firmly adsorbed on the bottom of the seat frame 9, thereby achieving the purpose of convenient storage and use of the table. When adjusting the seat forward and backward, the four-way switch on the front side of the seat adjustment switch 8 is moved forward and backward, and the translation motor 11 drives the rotating shaft 12 to rotate, and the seat is translated on the slide rail 7 by the cooperation of the gear and the rack.
