Embodiment 1

[0029] refer to Figure 1 to Figure 3 ,as well as Figure 7 , is Embodiment 1 of the present invention, specifically:

[0030] A wheelchair comprises a seat 8, two front wheels 5 arranged parallel to each other under the front part of the seat 8, two rear wheels 7 arranged parallel to each other under the rear part of the seat 8, the rear wheels 7 It is spaced apart from the front wheel 5, and also includes a first electric push rod 1, a second electric push rod 2, and two middle wheels 6 arranged parallel to each other under the seat 8, and the middle wheel 6 is arranged on the rear wheel 7. Between the front wheel 5 and the diameter of the middle wheel 6 is smaller than the diameter of the rear wheel 7, one end of the first electric push rod 1 is connected to the seat 8, the other end of the first electric push rod 1 is connected with the middle wheel 6, and the second electric push rod 1 is connected to the middle wheel 6. One end of the rod 2 is connected to the seat 8, ...

Embodiment 2

[0038] refer to Figure 4 , which is the second embodiment of the present invention, specifically:

[0039] The difference from the above embodiment is that one end of the second electric push rod 2 is fixedly connected to the seat 8 . The above-mentioned second electric push rod 2 changes the height of the rear wheel 7 through the change of its own length, and only one rod is used to control the rear wheel 7, so that the improved wheelchair has a simple structure and is easy to use.

Embodiment 3

[0040] refer to Figure 5 , which is the third embodiment of the present invention, specifically:

[0041] The difference from the above embodiments is that one end of the first electric push rod 1 is fixedly connected to the seat 8 . The above-mentioned first electric push rod 1 changes the height of the middle wheel 6 through the change of its own length, and only one rod is used to control the middle wheel 6, so that the improved wheelchair has a simple structure and is easy to use.

Abstract

The invention discloses an improved wheelchair including a seat, two front wheels arranged parallel to each other under the front of the seat, two rear wheels arranged parallel to each other under therear of the seat. The rear wheels and the front wheels are arranged in front and back at intervals. The wheelchair also includes a first electric push rod, a second electric push rod, and two middlewheels disposed parallel to each other under the seat, wherein the middle wheels are disposed between the rear wheels and the front wheels, and the diameter of the middle wheels is smaller than that of the rear wheels. One end of the first electric push rod is connected to the seat, and the other end of the first electric push rod is connected with the middle wheel. One end of the second electricpush rod is connected with the seat, and the other end of the second electric push rod is connected with the rear wheel. The first electric push rod includes two screw assemblies. The improved wheelchair of the present invention has an obstacle-crossing function, and the improved wheelchair has a high push rod strength.

Description

technical field [0001] The invention relates to the field of travel means of transportation, in particular to an improved wheelchair. Background technique [0002] Wheelchairs are a tool of life for people with reduced mobility, but in public places outside of hospitals, it is rare to see people using improved wheelchairs. According to data released by the China Disabled Persons' Federation, at the end of 2010, there were 24.72 million physically disabled people in my country, accounting for about 1.8% of the total population. It can be seen from the above data that there are a large number of people who need to use wheelchairs, but few people use wheelchairs to travel, mainly due to the limitation of the functions of current wheelchairs. People who use wheelchairs will inevitably have obstacles that are difficult to cross. Using existing wheelchairs to travel will bring a lot of inconvenience to users. Contents of the invention [0003] The technical problem to be solve...
