Embodiment 1

[0023] refer to Figure 1 to Figure 3 ,as well as Figure 5 , which is Embodiment 1 of the present invention, specifically:

[0024] A shock-absorbing wheelchair comprises a seat 8, two front wheels 5 arranged parallel to each other under the front part of the seat 8, and two rear wheels 7 arranged parallel to each other under the rear part of the seat 8. The wheel 7 and the front wheel 5 are arranged at intervals front and back, and also include a first electric push rod assembly 1, a second electric push rod assembly 2, and two middle wheels 6 arranged parallel to each other below the seat 8, and the middle wheels 6 are arranged Between the rear wheel 7 and the front wheel 5, and the diameter of the middle wheel 6 is smaller than the diameter of the rear wheel 7, the first electric push rod assembly 1 includes a first electric push rod and is fixed to the first electric push rod The first shock absorber at the rear end, the second electric push rod assembly 2 includes a se...

Embodiment 2

[0034] refer to Figure 4 , which is the second embodiment of the present invention, specifically:

[0035] The difference from the above embodiment is that it also includes a third connecting rod 3, one end of the third connecting rod 3 is hinged to the seat 8, the other end is connected to the middle wheel 6, and the other end of the first electric push rod is hinged to the third connecting rod 3. The middle part is relatively connected with the middle wheel.

[0036] By adjusting the length of the first electric push rod assembly 1, the angle of the hinged seat 8 of the third connecting rod 3 changes accordingly, and the position of the middle wheel 6 changes accordingly, which can realize the functions of the above-mentioned embodiments, and is feasible in the present invention One of the examples.

[0037] Further, it also includes a horizontal shaft arranged between the two rear wheels 7, the two ends of the horizontal shaft are respectively connected to the centers of...

Abstract

The invention discloses a shock-absorbing 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 the rear 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 middle wheels 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 thanthat of the rear wheels. The first electric push rod assembly includes a first electric push rod and a first shock absorber secured to a rear end of the first electric push rod. The second electric push rod assembly includes a second electric push rod and a second shock absorber fixedly connected to the rear end of the second electric push rod, the front end of the first electric push rod assemblyis connected to a seat, the rear end of the first electric push rod assembly is connected to the middle wheels, the front end of the second electric push rod assembly is connected to the seat, and the rear end of the second electric push rod assembly is connected to the rear wheels. The shock-absorbing wheelchair of the present invention has an obstacle-crossing function.

Description

technical field [0001] The invention relates to the field of travel means of transportation, in particular to a shock-absorbing wheelchair. Background technique [0002] Wheelchairs are a tool of life for people with limited mobility, but in public places outside hospitals, few people use wheelchairs. According to a survey 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 solved by the invention...
