Abstract
Description
Technical Field
[0001] This invention relates to the field of elevator technology, and more particularly to an elevator with a voice recognition system. Background Technology
[0002] Scissor lifts, as a common type of aerial work platform, are widely used in construction, warehousing, and manufacturing industries. Traditional scissor lifts are mainly controlled by manual buttons and foot switches. In recent years, some high-end models have introduced touchscreen or wireless remote control technology. With industrial development, intelligent human-machine interaction has become a trend, but the existing control methods still have problems such as operation delays and reliance on physical contact, resulting in a relatively low overall penetration rate of intelligent systems.
[0003] As mentioned above, the most common scissor lifts on the market currently use manual buttons, foot switches, wireless remote controls, and touchscreens for lifting control. 1. Manual buttons and foot switches: Physical buttons / switches are installed on the side of the lifting platform, directly controlling the hydraulic valves via relays. The advantage is low cost, but the disadvantage is that the user must move to the vicinity of the physical buttons / switches and operate them manually. 2. Wireless remote control: It uses a 2.4GHz radio frequency module. The advantage is freedom of movement, but the disadvantage is that it requires carrying additional equipment and is susceptible to interference. 3. Touchscreen control: Integrated 7-inch industrial touchscreen supports multi-level menu operation. The advantage is intuitive interaction, but the disadvantage is that manual operation is still required, leading to a high rate of accidental touches in vibrating environments.

[0018] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Example
[0019] Please refer to Figure 1-8 A lift with a voice recognition system includes a vehicle base 1. To facilitate the flexible movement of the vehicle base 1, a drive wheel 3 is provided at the lower end of the vehicle base 1. In order to enable the lifting of the staff, a scissor hydraulic mechanism 4 is installed on the inner side of the vehicle base 1. A bearing base 5 is fixed at the upper end of the scissor hydraulic mechanism 4. When the bearing base 5 is not raised, a protective frame 2 is fixed at the upper end of the vehicle base 1 to protect the outside of the bearing base 5. When the bearing base 5 is raised, a protective barrier 6 is fixed at the outside of the bearing base 5 to protect the staff standing on the top of the bearing base 5. Side handrails 7 are fixed on both sides of the upper end of the protective barrier 6. In order to further enclose the protective fence 6 and ensure the safety of workers during high-altitude operations, a fence railing 8 is installed at one end of the protective fence 6. To facilitate the flexible opening or closing of the fence railing 8 and to facilitate workers to enter and exit the protective fence 6, hinges 9 are symmetrically installed between the lower end of the fence railing 8 and the supporting base 5. When the fence 8 is closed, in order to limit and fix the position of the fence 8, both sides of the upper end of the fence 8 are slidably connected with pull rods 10. One side of each pull rod 10 passes through the side support 7 and is slidably connected to the side support 7. A spring 11 is fixed between the outer side of the other side of the pull rod 10 and the fence 8. When staff enter the inner side of the protective enclosure 6 and stand on the upper part of the support base 5, in order to enable voice control of the extension and retraction of the scissor hydraulic mechanism 4 and thus facilitate control of their own lifting and moving, the support base 5 is provided with a guide groove 14. The lower end of the protective enclosure 6 and the corresponding position of the guide groove 14 are provided with a through groove 15. An L-shaped mounting frame 19 is slidably connected between the guide groove 14 and the through groove 15. A telescopic cylinder 24 is installed inside the L-shaped mounting frame 19. A mounting support 25 is fixed to the telescopic end of the telescopic cylinder 24. A support shaft 26 is fixed to the inner side of the mounting support 25. An arc-shaped support block 29 is rotatably connected to the outer side of the lower end of the support shaft 26. A hollow support arm 30 is fixed to the outer side of the arc-shaped support block 29. A microphone 33 is installed at the end of the hollow support arm 30 away from the arc-shaped support block 29. A power supply module 16, a guide post 17, and a reciprocating screw 18 are respectively provided on the inner side of the guide groove 14. The guide post 17 and the reciprocating screw 18 are both fixed to the bearing base 5. In order to drive the L-shaped mounting frame 19 to move horizontally, the L-shaped mounting frame 19 is located outside the guide post 17 and is slidably connected to the guide post 17. An internal threaded cylinder 20 is rotatably connected inside the L-shaped mounting frame 19 and outside the reciprocating screw 18. The inner side of the internal threaded cylinder 20 is threadedly connected to the reciprocating screw 18. A first spur gear 21 is fixed on the outer side of the internal threaded cylinder 20 and inside the guide groove 14. A first motor 22 is installed inside the L-shaped mounting frame 19 and outside the first spur gear 21. A second spur gear 23 is fixed at the output end of the first motor 22. The second spur gear 23 meshes with the first spur gear 21. In order to enable the arc-shaped support block 29 to rotate flexibly around the support shaft 26, a third flat gear 27 is fixed on the outer side of the upper end of the support shaft 26. A second motor 31 and a power adapter 39 are respectively installed on the inner side of the hollow support arm 30. A fourth flat gear 32 is fixed at the output end of the second motor 31. The fourth flat gear 32 meshes with the third flat gear 27. To ensure the normal operation of the voice recognition system, a voice processor 37 and a wireless controller 38 are respectively installed at the upper end of the hollow support arm 30. In order to respond to the voice commands issued by the staff, a feedback speaker 36 is installed at the lower end of the hollow support arm 30. The second motor 31, microphone 33, feedback speaker 36, voice processor 37, and wireless controller 38 are all electrically connected to the power adapter 39. Among them, the infrared transmitter 12, infrared receiver 13, first motor 22, and telescopic cylinder 24 are all electrically connected to the power supply module 16. An emergency lifting button 28 is installed on the outer side of the upper end of the L-shaped mounting frame 19. The emergency lifting button 28 is electrically connected to the scissor hydraulic mechanism 4. The emergency lifting button 28 is used to realize emergency lifting control in the event of voice function failure, further reducing safety hazards. It should be noted that the device structure and accompanying drawings of this invention mainly describe the principle of this invention. In terms of the technical aspects of this design principle, the setting of the device's power mechanism, power supply system and control system, etc., is not fully described. However, those skilled in the art who understand the principle of the above invention can clearly understand its power mechanism, power supply system and control system. The control method in the specific application document is automatic control through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. Example
[0020] The elevator with a voice recognition system provided in Embodiment 1 is further optimized. Specifically, when staff enter or exit the protective enclosure 6, infrared transmitters 12 and infrared receivers 13 are respectively installed on both sides of the protective enclosure 6 near the fence 8 to detect the entry and exit of staff. Then, when a staff member enters the protective enclosure 6 and is detected by the infrared transmitters 12 and infrared receivers 13, the L-shaped mounting frame 19 is automatically controlled to move laterally, the telescopic cylinder 24 extends its telescopic end, and the arc-shaped support block 29 rotates around the support shaft 26. Figure 2 As shown, this allows the microphone 33 to be moved closer to the staff member's mouth, making it convenient to receive the staff member's voice commands at any time; When receiving voice commands through microphone 33, in order to reduce the adverse effects of surrounding construction noise, a receiver cover 34 is fixed to the outside of microphone 33, and a noise-reducing cotton pad 35 is laid on the inside of receiver cover 34. The receiver cover 34 and the noise-reducing cotton pad 35 are used to amplify the voice commands and reduce noise to achieve clear transmission of the voice commands.
[0021] Working principle: such as Figure 1 As shown, when the infrared transmitter 12 and infrared receiver 13 detect that a worker has entered the inner side of the protective enclosure 6 and is standing on the support base 5, the first motor 22 is automatically started to drive the second spur gear 23 to rotate. The meshing of the second spur gear 23 with the first spur gear 21 drives the internal threaded cylinder 20 to rotate. The threaded connection between the internal threaded cylinder 20 and the reciprocating screw 18 drives the L-shaped mounting frame 19 to move laterally inside the guide groove 14 and through groove 15 through the guide post 17, so that the L-shaped mounting frame 19 moves to the center outside the protective enclosure 6. At the same time, the telescopic cylinder 24 is automatically controlled to drive the mounting support 25 to move upward. At the same time, the second motor 31 is automatically started to drive the fourth spur gear 32 to rotate. The meshing of the fourth spur gear 32 with the third spur gear 27 drives the arc-shaped support block 29 to rotate and unfold around the support shaft 26. At this time, the microphone 33 and the receiver cover 34 can move and get closer to the worker's mouth, so as to receive the worker's voice commands at any time. Then, after the staff issued the lifting command, the scissor-type hydraulic mechanism 4 was used to lift the supporting base 5, and finally, as... Figure 2The lifting action is completed as shown. After the high-altitude operation is completed, the worker issues a descent command. At the same time, the scissor hydraulic mechanism 4 drives the support base 5 to slowly descend, while the automatic control system automatically resets the L-shaped support frame 19, support base 25, and hollow support arm 30, ultimately returning them to their original positions. Figure 1 The layout shown is for easy use next time.
[0022] In this invention, the overall structural design enables contactless operation, improving ease of use and efficiency. It allows staff to control the lifting and moving of the support base 5 directly via voice commands without having to move to a specific location or carry a remote control. At the same time, the receiver cover 34 and noise-reducing pad 35 are used to reduce noise and ensure clear transmission of voice commands. Compared with touch selection in complex menus, this method ensures more accurate transmission of the operation intention and improves the precision of control.
