[0002] A voice dialogue robot is an artificial intelligence device that can interact with users through voice. It can receive user voice input and reply to users through voice synthesis technology to achieve dialogue and communication with users. The use scenarios of voice dialogue robots are extremely wide. For example, they are used in smart homes to control home appliances, query information, provide schedule services, and are also used in large places such as large shopping malls or museums to provide tourists with guided tours, guide tourists or customers to browse shopping malls or museums, and introduce exhibits or merchandise related information. At present, when voice dialogue robots provide guidance in large shopping malls, they often need to take escalators to reach different floors. When going up and down escalators, if the base of the semantic dialogue robot is high off the ground, it is easy to tilt or even roll over. If the base is low, a base collision accident will occur, affecting the normal use of the escalator. Therefore, there is an urgent need for a voice dialogue robot drive base that can automatically raise and lower the base height and smoothly go up and down escalators. Utility Model Content

[0005] Furthermore, the outer surface of the threaded rod is provided with a spiral thread, a connecting piece is meshedly connected to the thread, the outer surface of the lower end of the connecting piece is fixedly connected to the inner ring of the deep groove ball bearing, and the outer ring of the deep groove ball bearing is embedded and fixedly installed in the bottom of the shell.

[0006] Furthermore, the threaded rod passes through the connecting piece and the deep groove ball bearing, the bottom of the threaded rod is fixedly connected to a driving wheel, and the outer surface of the upper end of the connecting piece is provided with vertical threads.

[0007] Furthermore, a gear disc is fixedly connected to the end of the motor output shaft, and the outer ring of the gear disc is provided with vertical teeth, and the vertical teeth are all engaged with the vertical threads on the outer surface of the upper end of the connecting member.

[0008] Furthermore, a non-slip pad is provided at the bottom of the shell on the outside of the lifting mechanism, and a visual sensor is embedded at one end of the shell in the forward direction.

[0009] The beneficial effects of the voice dialogue robot driving base of the utility model are as follows:

[0015] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 1-3As shown, a voice dialogue robot driving base includes a shell 1, a lifting mechanism 2 and a motor 3. Four lifting mechanisms 2 are fixedly installed at equal distances on the bottom of the shell 1. The motor 3 is fixedly installed at the top of the shell 1 corresponding to the center between the lifting mechanisms 2. The lifting mechanism 2 includes a threaded rod 201, a connecting piece 202, a deep groove ball bearing 203 and a driving wheel 204.

[0017] The outer surface of the threaded rod 201 is provided with a spiral thread, and a connecting piece 202 is meshed and connected to the thread. The outer surface of the lower end of the connecting piece 202 is fixedly connected to the inner ring of the deep groove ball bearing 203, and the outer ring of the deep groove ball bearing 203 is embedded and fixedly installed in the bottom of the shell 1; when the connecting piece 202 rises or falls in the threaded rod 201, the deep groove ball bearing 203 can drive the shell 1 to rise or fall synchronously.

[0018] The threaded rod 201 passes through the connecting piece 202 and the deep groove ball bearing 203 . The bottom of the threaded rod 201 is fixedly connected to a driving wheel 204 . The outer surface of the upper end of the connecting piece 202 is provided with vertical threads.

[0019] A toothed disc 301 is fixedly connected to the end of the output shaft of the motor 3, and the outer ring of the toothed disc 301 is provided with vertical teeth, and the vertical teeth are engaged with the vertical threads on the outer surface of the upper end of the connecting member 202; the toothed disc 301 is driven by the output shaft of the motor 3, and the toothed disc 301 is transmitted to the connecting member 202, so as to realize repeated and precise control of the lifting and lowering movement of the housing 1.

[0020] An anti-skid pad 102 is provided at the bottom of the housing 1 outside the lifting mechanism 2, and a visual sensor 101 is embedded at one end of the housing 1 in the forward direction; the anti-skid pad 102 is used to prevent rollover, and the visual sensor 101 is used to identify the road conditions on the movement route.

[0021] The specific working principle is as follows:

The inner ring of the deep groove ball bearing 203 is fixedly connected to the lower end of the outer surface of the connecting member 202. The connecting member 202 and the inner ring of the deep groove ball bearing 203 rotate synchronously, and the outer ring of the deep groove ball bearing 203 is fixedly embedded in the bottom of the shell 1. When the connecting member 202 is lifted and lowered, the deep groove ball bearing 203 is used to transmit the transmission, so that the shell 1 and the connecting member 202 can be lifted and lowered synchronously. When the visual sensor 101 provided at the shell 1 of the driving base of the utility model detects that there is an escalator in or out of the forward direction, the motor 3 works, so that the shell 1 can be lifted and lowered, so that when entering or exiting the escalator, the voice dialogue robot can run smoothly to avoid accidents. A spiral thread is provided on the outer surface of the threaded rod 201, and a connecting piece 202 is meshed and connected to the thread. The inner ring of the deep groove ball bearing 203 is fixedly connected to the outer surface of the lower end of the connecting piece 202. The outer ring of the deep groove ball bearing 203 is embedded and fixedly installed in the bottom of the shell 1. The end of the output shaft of the motor 3 is fixedly connected to a gear disk 301. The outer ring of the gear disk 301 is provided with vertical teeth. The vertical teeth are meshed with the vertical threads on the outer surface of the upper end of the connecting piece 202. This solves the problem mentioned in the background technology that "when a voice dialogue robot provides guidance in a large shopping mall, it often needs to take an escalator to reach different floors. When going up and down the escalator, if the base of the semantic dialogue robot is high off the ground, it is easy to tilt or even overturn. If the base is low, a base collision accident will occur, affecting the normal use of the escalator."
