[0021] The following are specific embodiments of the present application and further describe the technical solutions of the present application in conjunction with the drawings, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to help a comprehensive understanding of the embodiments of the present application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, in order to be clear and concise, the description of known functions and structures is omitted.
[0022] It should be noted that the embodiments and features in the present application can be combined with each other without conflict.
[0023] The present application provides a driving device suitable for small elevators in family residences, such elevators are usually used to connect multiple floors of villas, and facilitate the vertical transportation of residents or visitors. The driving device is used to drive the car to move along the extension direction of the guide rail.
[0024] Reference Figures 1 to 3 The self-driving rail elevator with the pressing driving device 30 includes a plurality of first limiting wheels 321 and a plurality of second limiting wheels 322, and a driving source 31. The first limiting wheels 321 and the second limiting wheels 322 are rotatable, and the driving source 31 is used to provide power. The first limiting wheels 321 and the second limiting wheels 322 can reversely press on the guide surfaces of the guide rail 10 on both sides, the first limiting wheels 321 are used to press on the first guide surface 11 of the guide rail 10, the second limiting wheels 322 are used to press on the second guide surface 12 of the guide rail 10, and the first limiting wheels 321 and the second limiting wheels 322 are located between the first guide surface 11 and the second guide surface 12 of the guide rail 10. Among all the first limiting wheels 321 and all the second limiting wheels 322, at least part of the limiting wheels 32 are driven as driving wheels by the driving source 31. Specifically, the driving source 31 is a motor. As shown in the figure, the driving device 30 is used to drive the car 20 to move along the extension direction of the guide rail 10. Figure 5
[0025] The limiting wheels 32 include the first limiting wheels 321 and the second limiting wheels 322, at least part of which are driving wheels. In an embodiment, part of the limiting wheels 32 are driving wheels, and the driving wheels are in power connection with the driving source 31, and part of the limiting wheels 32 are guide wheels, which can rotate freely during the up and down movement of the driving device 30. In an embodiment, all the limiting wheels 32 are driving wheels, and are in power connection with the driving source 31. Further, when the driving device 30 includes M1 first limiting wheels 321 and M2 second limiting wheels 322, the number of limiting wheels M is M1+M2, and the number of driving wheels can be any value between 1 and M. The number of driving wheels can be specifically set according to actual conditions, which will not be described here.
[0026] Specifically, the driving device 30 comprises a driving wheel and a driving source 31. The driving wheel is pressed against the guide rail 10 so that a friction force can be generated between the driving wheel and the guide rail 10. When the driving wheel rotates, the up-and-down movement can be achieved by means of the friction force between the driving wheel and the guide rail 10. The driving source 31 is connected with the driving wheel in a power manner, and the driving source 31 can output power to drive the driving wheel to rotate. It should be understood that the car 20 can be separately installed on other guide rails or can be installed on the guide rail 10, and the car 20 can move up and down along the guide rail 10. The above structure directly drives the elevator car to move up and down by means of the driving wheel installed on the elevator car, without the need to set a counterweight, a traction or a hoisting cable. The hoistway is simple in arrangement, high in utilization rate, and beautiful in appearance. The lifting speed and the lifting height are not limited. The tire friction drive is adopted, the tire can reduce vibration and noise, has small wear and low noise, runs stably and comfortably, and has low maintenance cost.
[0027] Specifically, the driving device 30 is used to drive the car to move along the extension direction of the guide rail 10. The driving device 30 upwardly supports the car 20 of the elevator, and the connection relationship between the driving device 30 and the car 20 of the elevator can be a connected relationship or a non-connected relationship. Here, it is only limited that the driving device 30 has an upward support for the car 20 of the elevator to bear the gravity load from the car 20 of the elevator. During operation, the driving device 30 and the car of the elevator can synchronously move up and down. The connection relationship between the driving device 30 and the car 20 can be a fixed connection or a movable connection. In one technical solution, the driving device 30 is arranged on the car, and a fixed connection relationship is adopted between the support of the driving device 30 and the car. In one technical solution, the driving device 30 is arranged on a structure fixedly connected with the car. In one technical solution, the driving device 30 is independent of the car 20, and is movably connected with the car 20 through a connecting piece.
[0028] Reference Figures 1 to 3 , and Figure 5 , the guide rail 10 is provided with a first guide surface 11 and a second guide surface 12, and the first guide surface 11 is located opposite to the second guide surface 12. As Figure 1As shown, the first guide surface 11 is located at the left side and faces the right side, and the second guide surface 12 is located at the right side and faces the left side. The first limiting wheel 321 is pressed on the first guide surface 11 from right to left, and the second limiting wheel 322 is pressed on the second guide surface 12 from left to right. The first limiting wheel 321 and the second limiting wheel 322 are respectively pressed on the structures of the left and right guide rails 10. It should be understood that the first guide surface 11 and the second guide surface 12 are two guide surfaces on the guide rail 10, and their structures and shapes are different depending on the structure of the guide rail 10. Further, the first limiting wheel 321 and the second limiting wheel 322 are respectively pressed on the structures of the left and right guide rails 10, and the pressing forces of the first limiting wheel 321 and the second limiting wheel 322 on the guide rail 10 are in opposite directions, so that the driving device 30 can be stably limited on the guide rail 10. Therefore, the pressing structure formed by the first limiting wheel 321 and the second limiting wheel 322 can limit the driving device 30 on the guide rail 10, and can stably move the driving device 30 up and down.
[0029] In an embodiment of the present application, the first limiting wheel 321 and the second limiting wheel 322 are arranged in pairs, and the first limiting wheel 321 and the second limiting wheel 322 constituting a pair are arranged at the same height.
[0030] Figure 1 A pair of limiting wheels constituted by the first limiting wheel 321 and the second limiting wheel 322 is shown, and the first limiting wheel 321 and the second limiting wheel 322 are at the same height and are pressed on the structures of the left and right guide rails 10 in opposite directions from the same height. In this way, the first limiting wheel 321 and the second limiting wheel 322 constituting a pair can offset each other's pressure on the guide rail 10. Further reference Figure 2 , the pressing driving device includes n pairs of limiting wheels constituted by the first limiting wheel 321 and the second limiting wheel 322, and n is set to be between 1 and 10. Reference Figure 2 A pair of limiting wheels constituted by the first limiting wheel 321 and the second limiting wheel 322 occupies a height position, and each pair of limiting wheels is distributed along the height direction.
[0031] In an embodiment of the present application, in any pair of limiting wheels constituted by the first limiting wheel 321 and the second limiting wheel 322, only one of the limiting wheels is driven by the driving source as a driving wheel, and the other is set to be freely rotatable.
[0032] In an embodiment of the present application, in the limiting wheel driven by the driving source, the limiting wheel has a one-to-one correspondence with the driving source. Here, the driving source 31 and the limiting wheel 32 as the driving wheel have a one-to-one correspondence.
[0033] Further reference Figure 4In all the first limit wheels 321 and all the second limit wheels 322, the limit wheel corresponds to the driving source 31 one by one, and the corresponding driving source 31 provides driving force for the corresponding limit wheel. Here, all the limit wheels are driving wheels, and each driving wheel corresponds to a driving source 31, and each limit wheel is driven by an independent driving source 31. As shown in Figure 4 The driving device 30 includes M1 first limit wheels 321 and M2 second limit wheels 322, and the number of limit wheels M is M1+M2. The number of driving wheels can be any value between 1 and M.
[0034] The present application provides a driving device suitable for small elevators in family residences, which adopts a supporting and pressing structure combined with a guide rail, and the first limit wheel and the second limit wheel can reversely support and press on the guide surface of the guide rail on both sides, so as to stably limit the driving device on the guide rail.
