It uses communication technology, audio technology, video technology, and software technology to achieve paperless meetings through the electronic exchange and display of documents. The intelligent conference machine is the core component of the paperless conference system and plays an important role in information display. According to different actual usage requirements, the height of the intelligent conference machine can be adjusted. Currently, only mobile intelligent conference machines can achieve height adjustment. For traditional wall-mounted intelligent conference machines, the height adjustment method is rarely used and cannot meet actual usage requirements. Summary of the invention

[0012] The utility model is described in detail below in conjunction with specific implementation methods:

[0013] like Figure 1 and Figure 2The height adjustment mechanism of an intelligent conference machine shown in the figure includes a base 1, a bracket 2, a linear rack 21, a linear slide 3, a slider 4, a connecting plate 5, a servo motor 6, a gear commutator 61, an electromagnet 7, a guide rod 8, a spring 82, a limiting cylindrical pin 9 and a carrier plate 91. The two brackets 2 are fixedly mounted on the base 1, the linear slide 3 is fixedly mounted on the bracket 2, the linear rack 21 is fixedly mounted on the inner side of the right linear slide 3, the slider 4 is slidably mounted on the linear slide 3, and the two sliders 4 are connected by a connecting plate. 5 is fixedly connected, the servo motor 6 and the gear commutator 61 are fixedly installed on the connecting plate 5, the output shaft of the servo motor 6 is transmission-connected with the power input shaft of the gear commutator 61, a gear is fixedly installed on the power output shaft of the gear commutator 61, and the gear is meshed and transmission-connected with the linear rack 21, the slider 4 is provided with an installation area 41, the slider 4 is provided with a guide hole connected with the installation area 41, the limiting cylindrical pin 9 is slidably installed in the guide hole, and the carrier plate 91 is fixedly installed Installed on the top of the limiting cylindrical pin 9, four guide rods 8 are distributed in a rectangular shape and fixedly installed in the installation area 41, the carrier plate 91 is slidably installed on the guide rod 8, the spring 82 is sleeved and installed on the guide rod 8, the upper and lower ends of the spring 82 act on the slider 4 and the carrier plate 91 respectively, the electromagnet 7 is fixedly installed in the installation area 41, and a permanent magnet is fixedly installed on the top of the carrier plate 91. The limiting cylindrical pin 9 can be embedded in the bolt hole 30 of the linear slide 3, and the diameter of the bolt hole 30 is the limiting The limiting cylindrical pin 9 is 1.1-1.3 times the diameter of the limiting cylindrical pin 9, so that the limiting cylindrical pin 9 can be embedded in the bolt hole 30 for limiting. The bolt holes 30 are arranged in a linear array on the linear slide rail 3. The servo motor 6 drives the gear commutator 61 to rotate. The gear commutator 61 drives the gear to rotate after power reversing. When the gear is engaged with the linear rack 21 for transmission, the slider 4 can be driven to adjust up and down along the linear slide rail 3. The main body of the smart conference machine is directly fixed on the slider 4 through installation, and the base 1 is fixed on the wall.

[0014] A shaft sleeve 81 is fixedly sleeved on the top of the guide rod 8, and the upper end of the spring 82 acts on the shaft sleeve 81, thereby shortening the length of the spring 82 and making the spring 82 have better elastic performance.

[0015] The electromagnet 7 is screwed and fixedly installed in the installation area 41 of the slider 4 by means of a fastening bolt 40. When the electromagnet 7 needs to be repaired or replaced, the fastening bolt 40 can be unscrewed to facilitate its removal.

[0016] The top surfaces of the servo motor 6 and the gear commutator 61 are 3 cm lower than the top surface of the slider 4 to avoid interference between the top surfaces of the servo motor 6 and the gear commutator 61 and the main body of the intelligent conference machine during installation.

[0017] The servo motor 6 and the electromagnet 7 are respectively connected to the control switch through the circuit. After pressing the ascending or descending adjustment control button of the control switch, the servo motor 6 first rotates in the opposite direction, driving the slider 4 to move 0.5-1 cm in the opposite direction along the linear slide 3, so that the limiting cylindrical pin 9 does not contact the inner wall of the bolt hole 30 of the linear slide 3, and then the electromagnet 7 is started, so that the suction end of the electromagnet 7 and the permanent magnet on the top of the carrier plate 91 are in a state of opposite polarity attraction, and the electromagnet 7 overcomes the elastic force of the spring 82 and sucks the carrier plate 91, the permanent magnet and the limiting cylindrical pin 9 upward. After the limiting cylindrical pin 9 comes out of the bolt hole 30, the limiting effect is released, and the servo motor 6 drives the main body of the intelligent conference machine to move to the required height. The single moving distance of the servo motor 6 corresponds to the distribution position of the bolt hole 30 of the linear guide rail 3, thereby ensuring that after a single height adjustment of the main body of the intelligent conference machine, the limiting cylindrical pin 9 is always in a coaxial state with the bolt hole 30. After the electromagnet 7 is powered off, the spring 82 pushes the carrier plate 91 to move downward, so that the limiting cylindrical pin 9 is embedded in the bolt hole 30 to form a limiting effect, thereby preventing the all-in-one conference machine from falling downward.
