Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a height-adjustable table and chair, comprising a height-adjusting mechanism 1, and an auxiliary mechanism 2 is in contact with one side of the outer wall of the height-adjusting mechanism 1;

[0026] The height adjustment mechanism 1 includes two bases 101, the tops of the two bases 101 are fixedly installed with brackets 102, the tops of the two brackets 102 are fixedly installed with forward and reverse motors 103, one side of the outer wall of the two forward and reverse motors 103 is fixedly installed with a driving roller 104, the outer wall of the two driving rollers 104 is fixedly sleeved with a gear 105, the tops of the two brackets 102 are fixedly installed with a fixing plate 106, and the outer walls of the two driving rollers 104 are movably inserted in the inside of the two fixing plates 106, the outer walls of the two gears 105 are meshed and connected with a tooth row 107, and a table body 108 is fixedly installed between the tops of the two tooth rows 107, and the outer wall of the table body 108 is fixedly installed with a tooth row 107. A controller 109 is fixedly installed on one side of the wall, and one side of the outer wall of the controller 109 is electrically connected to the outer walls of the two forward and reverse motors 103, three sleeves 110 are fixedly installed on the top of the two bases 101, six sleeve columns 111 are fixedly installed on the bottom of the table body 108, and the outer walls of the six sleeve columns 111 are movably inserted into the six sleeves 110, four limit rods 112 are fixedly installed on the top of the two bases 101, eight limit holes 113 are opened at the bottom of the table body 108, and the outer walls of the eight limit rods 112 are movably inserted into the eight limit holes 113, and a baffle 114 is fixedly installed on one side of the outer wall of the two bases 101.

[0027] The effect achieved by the entire embodiment 1 is that when the user sits on the chair and needs to adjust the height of the table, the forward and reverse motors 103 on the two brackets 102 are started to drive the two driving rollers 104 to rotate. Since the two gears 105 and the two gear rows 107 are meshed and connected, and the two gear rows 107 are installed at the bottom of the table body 108, the two gears 105 are driven to rotate through the two driving rollers 104, thereby driving the gear rows 107 and the table body 108 to move up and down, and adjust their height. Secondly, six sleeve columns 111 are installed at the bottom of the table body 108, and the six sleeve columns 111 are all movably inserted in the six sleeves 110 and will not move out of the sleeves 110, and the eight limit rods 112 on the two bases 101 are all movably inserted in the eight limit holes 113, thereby improving the stability of the up and down movement adjustment of the table body 108, satisfying that users of different heights can maintain a level and comfortable state with the desktop, and it is intelligent, improves the learning efficiency of the user, and improves the use effect of the table and chair combination.

[0028] Embodiment 2, as Figure 2-Figure 5 As shown, the auxiliary mechanism 2 includes a chair frame 201, and two horizontal plates 202 are fixedly installed on the outer wall of the chair frame 201, and two electric push rods 203 are fixedly installed on the top of the two horizontal plates 202. Two connecting plates 204 are fixedly installed between the output ends of the two electric push rods 203, and a seat cushion assembly 205 is fixedly installed between the opposite sides of the outer walls of the two connecting plates 204.

[0029] The effect achieved by the entire embodiment 2 is that when the user uses the chair, the four electric push rods 203 on the two horizontal plates 202 can be started to drive the two connecting plates 204 and the seat cushion assembly 205 to move up and down, thereby further meeting the user's requirements for the seat height and adjusting it, thereby improving the use effect of the smart table and chair assembly.

[0030] When the utility model is in use, first, when the user needs to use the table and chair combination to work or study, the four electric push rods 203 are started first, so that the four electric push rods 203 drive the seat cushion assembly 205 to move up and down, so as to meet the most suitable seat height for the user, and then the two forward and reverse motors 103 are started through the controller 109, and under the action of the two fixing plates 106, the two driving rollers 104 and the two gears 105 are driven to rotate. Since the two gear rows 107 are installed at the bottom of the table body 108 and are meshed with the two gears 105, the table body 108 can be driven to move up and down and the height can be adjusted. Secondly, the six sleeve columns 111 installed at the bottom of the table body 108 are movably inserted into the six sleeves 110, and the table body 108 is movably sleeved on the eight limit rods 112 through eight limit holes 113, thereby improving the stability of the height adjustment of the table body 108. In general, through the functions of the height adjustment mechanism 1 and the auxiliary mechanism 2, it is convenient for the user to adjust the height thereof, and it is intelligent, so as to meet the needs of people of different heights to use the table and chair combination, and enable the learners to maintain the best learning state with the desktop, thereby improving the learning efficiency, and thus improving the use effect of the height-adjustable intelligent table and chair combination.
