[0018] The following is a specific embodiment of the application and further describes the technical solutions of the application in combination with the drawings, but the 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 application. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the application. In addition, in order to be clear and concise, the description of known functions and structures is omitted.

[0019] It should be noted that the embodiments and features in the embodiments can be combined with each other without conflict.

[0020] The application provides a driving device suitable for a small elevator in a family house, which is combined with a guide rail in a way that two side limit wheels are used to limit the driving device, so that the driving device can be stably limited on the guide rail structure.

[0021] REFERENCE Figures 1 to 3The self-driven track elevator with the pair of clamping driving device 30 comprises a plurality of first limiting wheels 321 and a plurality of second limiting wheels 322, and the first limiting wheels 321 and the second limiting wheels 322 are rotatable. The driving source 31 is used for providing power. The first limiting wheels 321 and the second limiting wheels 322 can clamp the guide rail structure 10 located therebetween from both sides, and in all the first limiting wheels 321 and all the second limiting wheels 322, at least part of the limiting wheels are driven wheels driven by the driving source. Specifically, the driving source 31 is a motor. As shown in Figure 5 The driving device 30 is used to drive the car 20 to move along the extension direction of the guide rail structure 10.

[0022] The limiting wheels 32 comprise 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 part of the limiting wheels 32 are guide wheels which can rotate freely during the up-down movement of the driving device 30. In an embodiment, all the limiting wheels 32 are driving wheels and are connected to the driving source 31. Further, when the driving device 30 comprises N1 first limiting wheels 321 and N2 second limiting wheels 322, the number of limiting wheels N is N1+N2, and the number of driving wheels can be any value between 1 and N. The number of driving wheels can be specifically set according to actual conditions, which will not be described here.

[0023] Specifically, the driving device 30 comprises a driving wheel and a driving source 31. The driving wheel is pressed against the guide rail structure 10 so that friction can be generated between the driving wheel and the guide rail structure 10. When the driving wheel rotates, the up-down movement can be realized by means of the friction between the driving wheel and the guide rail structure 10. The driving source 31 is connected to the driving wheel and can output power to drive the driving wheel to rotate. It should be understood that the car 20 can be installed on other tracks or on the guide rail structure 10, and the car 20 can move up and down along the guide rail structure 10. The above structure directly drives the elevator car to move up and down by using the driving wheel installed on the elevator car, without the need to set a counterweight, a traction or a traction cable. The shaft 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, the wear is small, the noise is low, the operation is stable and comfortable, and the maintenance cost is low.

[0024] Specifically, the drive unit 30 is used to move the elevator car along the extension direction of the guide rail structure 10. The drive unit 30 supports the elevator car 20 upwards, and the drive unit 30 and the elevator car 20 can be connected or not connected. Here, it is only limited that the drive unit 30 provides upward support to the elevator car 20 and bears the gravity load from the elevator car 20. During operation, the drive unit 30 and the elevator car can move up and down synchronously. The connection between the drive unit 30 and the car 20 can be a fixed connection or a movable connection. In one technical solution, the drive unit 30 is arranged on the car, and the support of the drive unit 30 is fixedly connected to the car. In another technical solution, the drive unit 30 is arranged on a structure fixedly connected to the car. In yet another technical solution, the drive unit 30 is independent of the car 20 and is movably connected to the car 20 via a connector.

[0025] Continue to refer to Figures 1 to 3 The guide rail structure 10 includes a first guide surface 11 and a second guide surface 12, with the first guide surface 11 located opposite to the second guide surface 12. For example... Figure 1 As shown, the first guide surface 11 is located on the left side and faces left. The second guide surface 12 is located on the right side and faces right. The first limiting wheel 321 presses against the first guide surface 11 from left to right, and the second limiting wheel 322 presses against the second guide surface 12 from right to left. The first limiting wheel 321 and the second limiting wheel 322 clamp the guide rail structure 10 between the first guide surface 11 and the second guide surface 12 from the left and right sides. It should be understood that the first guide surface 11 and the second guide surface 12 are two opposite guide surfaces on the guide rail structure 10, and their structure and shape vary depending on the structure of the guide rail structure 10. It should be understood that the guide rail structure 10 here can refer to a whole guide rail or a part of the structure of a guide rail. Furthermore, the first limiting wheel 321 and the second limiting wheel 322 are clamped onto the guide rail structure 10 between the first guide surface 11 and the second guide surface 12 from opposite directions, and the clamping forces applied by the first limiting wheel 321 and the second limiting wheel 322 to the guide rail structure 10 are in opposite directions, which can smoothly confine the drive device 30 to the guide rail structure 10. Therefore, the clamping structure formed by the first limiting wheel 321 and the second limiting wheel 322 can confine the drive device 30 to the guide rail structure and can make the drive device 30 move up and down smoothly.

[0026] In one embodiment of this 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 set at the same height on both sides of the guide rail structure 10.

[0027] Figure 1A pair of limit wheels is shown, which is composed of a first limit wheel 321 and a second limit wheel 322. The first limit wheel 321 and the second limit wheel 322 are located at the same height and sandwich the guide rail structure 10 between the first guide surface 11 and the second guide surface 12 from the same height. In this way, the clamping force of the first limit wheel 321 and the second limit wheel 322 constituting a pair on the guide rail structure 10 can be mutually offset. Further reference Figure 2 , the driving device 30 includes n pairs of limit wheels composed of a first limit wheel 321 and a second limit wheel 322, and n is set to be between 1 and 10. Reference Figure 2 , a pair of limit wheels composed of a first limit wheel 321 and a second limit wheel 322 occupies a height position, and the limit wheels of each pair are distributed at intervals in the height direction.

[0028] In an embodiment of the present application, in any pair of limit wheels composed of a first limit wheel 321 and a second limit wheel 322, only one of the limit wheels acts as a driving wheel driven by the driving source, and the other is set to be freely rotatable.

[0029] In an embodiment of the present application, in the limit wheel 32 driven by the driving source 31, the limit wheel 32 has a one-to-one correspondence with the driving source 31. Here, the driving source 31 and the limit wheel 32 as a driving wheel have a one-to-one correspondence.

[0030] Further reference Figure 4 , in all first limit wheels and all second limit wheels, the limit wheels have a one-to-one correspondence with the driving sources 31, and the corresponding driving sources 31 provide driving force for the corresponding limit wheels. Here, all 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 Figure 4 shown, the driving device 30 includes N1 first limit wheels 321 and N2 second limit wheels 322, the number of limit wheels N is N1+N2, and the number of driving wheels can be any value between 1 and N.

[0031] The present application provides a driving device suitable for use in small elevators in family residences, which adopts a pair of limit wheels on both sides to clamp the guide rail, and can stably limit the driving device on the guide rail structure.
