[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] Please refer to Figure 1 - Figure 7 , a driving device of a stair lifting device, including a limit base 1, a seat 2 is fixedly assembled on the top of the limit base 1, a steel pipe 3 is fixedly assembled on the outer wall of the seat 2, armrests 4 are fixedly assembled on the tops of both ends of the steel pipe 3, a seat belt buckle 5 is fixedly assembled on the outer wall of one end of the steel pipe 3, a protection belt 6 is fixedly assembled on the outer wall of the other end of the steel pipe 3, a limit rod 7 is rotatably connected to the bottom of the seat 2, a connecting plate 8 is fixedly assembled on the outer wall of the seat 2, a limit shell 9 is fixedly assembled on the bottom of the connecting plate 8, a limit assembly 10, a drive assembly 11, a guide rail one 12 and a guide rail two 13 are respectively arranged on the outer wall of the limit base 1, and a rack 14 is fixedly assembled on the outer wall of the guide rail two 13.
[0026] In the above structure, when the user sits on the top of the seat 2, through manual operation by the user, the protection belt 6 is pulled out and stretched so that it is engaged with the socket of the seat belt buckle 5, thereby realizing the safety protection of the user and avoiding accidental falling during the lifting process. At the same time, by means of the design of the steel pipe 3 and the armrest 4, a suitable support position is provided for the user's arm to ensure the comfort of the user during use. In addition, through the combination of the guide rail one 12 and the guide rail two 13, the limit base 1 is accurately limited to ensure that it moves within the outer wall range of the guide rail one 12 and the guide rail two 13, and the rack 14 and the drive assembly 11 act together on the drive device to realize its stable movement, and the limit shell 9 protects the limit assembly 10 to ensure its stable operation.
[0027] In a preferred embodiment: The limit assembly 10 includes a rotating device 1001. The outer wall of the rotating device 1001 is fixedly assembled with a limit block 1002. The inner wall of the limit block 1002 is fixedly assembled with a guiding device 1003. The outer wall of the limit block 1002 is provided with a first protective shell 1004. The outer wall of the first protective shell 1004 is threadedly connected with a fixing bolt 1005.
[0028] In the above structure, when ensuring that the limit base 1 slides on the outer wall of the guide rail two 13, its moving process will cause the guiding device 1003 to rotate and rub on the outer wall of the guide rail one 12. By this mechanism, the limit base 1 is firmly fixed to ensure that the limit base 1 will not fall off during the moving process. At the same time, the rotating device 1001 rotates on the outer wall of the limit base 1, effectively ensuring that the limit base 1 will not get stuck during the turning process. Through the threaded connection mode of the fixing bolt 1005 and the first protective shell 1004, not only the limiting function of the first protective shell 1004 is realized, but also the protection effect of the internal structure of the limit assembly 10 is enhanced.
[0029] In a preferred embodiment: The drive assembly 11 includes a fixing device 1107. The outer wall of the fixing device 1107 is fixedly assembled with a motor 1101. One end of a limit column 1102 is fixedly assembled on the power output shaft of the motor 1101. The other end of the limit column 1102 is fixedly assembled with a gear 1103. The outer wall of the motor 1101 is provided with a second protective shell 1104. The outer wall of the fixing device 1107 is respectively fixedly assembled with a rotating column 1106 and a rotating rod 1105.
[0030] In the above structure, the driving output shaft of the motor 1101 drives the limit post 1102 to rotate, thereby causing the gear 1103 to rotate accordingly. The gear 1103 and the rack 14 are in meshing transmission mechanism to ensure that when the gear 1103 rotates, it can effectively drive the limit base 1 to move. In order to enhance the stability and guidance of the equipment, through the rotating rod 1105 and the rotating column 1106, they not only limit the guide rail two 13, but also are responsible for precisely guiding the limit base 1. When the equipment performs a moving action, the shafts of the rotating rod 1105 and the rotating column 1106 will rotate synchronously, thereby improving the speed and efficiency of the equipment during the lifting process.
[0031] In a preferred embodiment: The rotating device 1001 and the fixing device 1107 are both rotatably connected to the outer wall of the limit base 1, and the gear 1103 meshes with the rack 14 for transmission.
[0032] In the above structure, by rotatably connecting the rotating device 1001 and the fixing device 1107 to the outer wall of the limit base 1, the limit base 1 will not get stuck during lifting, and the limit base 1 can move smoothly obliquely upward or obliquely downward.
[0033] In a preferred embodiment: The guide rail one 12 is located inside the guiding device 1003, and the guide rail two 13 is located inside the driving assembly 11.
[0034] In the above structure, by the guide rail one 12 and the guide rail two 13 being located inside the guiding device 1003 and the driving assembly 11 respectively, the limit base 1 is limited, so that the limit base 1 will not fall off during movement.
[0035] In a preferred embodiment: The protective belt 6 is snap-connected to the inner wall of the seat belt buckle 5, and the connecting plate 8 is fixedly assembled to the top of the limit base 1.
[0036] In the above structure, by the protective belt 6 being snap-connected to the inner wall of the seat belt buckle 5, the user is fixed to prevent the user from falling off the equipment during use. The limit base 1 is used to limit the connecting plate 8 so that the connecting plate 8 will not fall off.
[0037] Working principle: When the user sits on the top of the device, manually pull out and stretch the protection belt 6 so that it is clamped with the socket of the seat belt buckle 5, thereby realizing the safety protection of the user and effectively avoiding the risk of falling during the lifting process. At the same time, the design of the steel pipe 3 and the handrail 4 provides support for the user to place the arms and improves the comfort during use. During the mechanical operation, the power output shaft of the motor 1101 drives the limit post 1102 to rotate, and then drives the gear 1103 to rotate. Through the meshing transmission of the gear 1103 and the rack 14, the gear 1103 can drive the limit base 1 to move when rotating. The rotating rod 1105 and the rotating column 1106 are used to limit the guide rail two 13 and guide the limit base 1 to ensure that the limit base 1 can slide smoothly on the outer wall of the guide rail two 13. When the limit base 1 moves, it will drive the guiding device 1003 to rotate and rub on the outer wall of the guide rail one 12 to fix the limit base 1 and ensure that it will not fall during the moving process. At the same time, the rotating device 1001 and the motor 1101 rotate on the outer wall of the limit base 1 to ensure that the limit base 1 will not get stuck during the turning process.
[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
