[0031] Example 1

[0032] Reference Figure 1-3 A new type of wheelchair includes a wheelchair frame 1 and wheelchair running wheels 2. A connecting shaft is fixed on the inner side of the bottom of the wheelchair frame 1, and both ends of the connecting shaft are rotatably connected to the wheelchair running wheels 2. An auxiliary driving mechanism is installed at the bottom of the wheelchair frame 1, and the auxiliary driving mechanism is used to drive the wheelchair running wheels 2 to move. A carrying mechanism is installed on the inner side of the wheelchair frame 1, and the carrying mechanism is used to provide an additional seat for people to rest.

[0033] The auxiliary driving mechanism includes a driving frame 3, guide wheels 4 and a balancing vehicle 5. The driving frame 3 is arranged at the bottom of the wheelchair frame 1, and guide wheels 4 are installed on both sides of one end of the driving frame 3. The balancing vehicle 5 is fixed to the other end of the driving frame 3. The balancing vehicle 5 can provide power to facilitate the guide wheels 4 to move by pushing the driving frame 3. It belongs to the existing mature technology and its working principle will not be described here.

[0034] A push handle 6 is fixed to one side of the top of the wheelchair frame 1, pedals 7 are fixed to both sides of the top of one end of the driving frame 3, and leg rests 8 are fixed to both sides of one end of the bottom of the wheelchair frame 1. Through the arrangement of the push handle 6, pedals 7 and leg rests 8, the user can sit on the main seat 9 more comfortably.

[0035] The carrying mechanism includes a storage cavity 10, a telescopic rod 11 and a secondary seat 12. A main seat 9 is fixed to the bottom of the inner side of the wheelchair frame 1, and a storage cavity 10 is opened on one side of the main seat 9. Two telescopic rods 11 are fixed to one end of the inner side of the storage cavity 10, and a secondary seat 12 is fixed to the extended end of the two telescopic rods 11. When the pusher needs to rest, the secondary seat 12 is pulled so that the secondary seat 12 extends from the storage cavity 10, so that the secondary seat 12 and the telescopic rod 11 extend through the inner side of the wheelchair running wheel 2 to the outside, and the pusher sits on the secondary seat 12 to rest. It can be understood that the telescopic rod 11 is a sleeve, pneumatic or electric push rod, which is convenient for moving the secondary seat 12.

[0036] The bottom of the auxiliary seat 12 is connected to a support frame 13 through a buckle. The support frame 13 can provide support for the auxiliary seat 12. After use, the support frame 13 can be removed and placed on the driving frame 3.

[0037] A direction rod 17 is provided on one side of the wheelchair frame 1, and the walking direction can be controlled by the direction rod 17, which belongs to the existing mature technology and will not be described in detail here.

[0038] Example 2

[0039] Embodiment 1 is further optimized, specifically, as Figure 4As shown, a balancing mechanism is assembled between the wheelchair frame 1 and the driving frame 3, and the balancing mechanism includes a tray 14, an elastic buffer ring 15 and a protective plate 16. The tray 14 is fixed on the top of the driving frame 3, and the elastic buffer ring 15 is arranged on the top of the tray 14. Two protective plates 16 are fixed to the top and bottom of the elastic buffer ring 15, and the two protective plates 16 located at the top are fixed to the wheelchair frame 1, and the two protective plates 16 located at the bottom are fixed to the tray 14. When the connecting shaft in the wheelchair running wheel 2 is offset by a certain angle, the wheelchair frame 1 squeezes the elastic buffer ring 15 through the protective plate 16 so that the elastic buffer ring 15 is in a compressed state. The elastic force generated by the elastic buffer ring 15 pushes the wheelchair frame 1 and the connecting shaft to reset. At the same time, a damper is arranged on the inner side of the elastic buffer ring 15 to ensure that the elastic buffer ring 15 rebounds slowly, thereby increasing the comfort of the wheelchair.

[0040] From the above, we can know that:

[0041] The utility model adopts the technical solutions of the above embodiments. At the same time, the implementation process of the above technical solutions is:

[0042] When in use, the auxiliary user sits on the main seat 9, and the pusher stands on the balance vehicle 5 to start the balance vehicle 5, which is then driven by the balance vehicle 5 to drive the frame 3 to move. The user controls the direction through the direction rod 17 to relieve fatigue caused by pushing the wheelchair through the push handle 6 for a long time;

[0043] When the pusher needs to take a rest, he pulls the auxiliary seat 12 so that the auxiliary seat 12 extends out from the storage cavity 10, and at the same time, the telescopic rod 11 unfolds, so that the auxiliary seat 12 and the telescopic rod 11 extend through the inner side of the wheelchair running wheel 2 to the outside, and then takes out the support frame 13 placed on the driving frame 3, connects the top of the support frame 13 with the bottom of the auxiliary seat 12 through a buckle, and the pusher sits on the auxiliary seat 12 to take a rest.

[0044] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:

[0045] 1. The utility model places a balance vehicle 5 behind the wheelchair, and the pusher can push the wheelchair by stepping on the balance vehicle 5, thereby alleviating fatigue caused by pushing the wheelchair for a long time. The user can control the direction through the direction rod 17.

[0046] 2. Two seats: A secondary seat 12 can be pulled out from under the main seat 9, which can be used as a coffee table or provide a comfortable seat for the elderly who push the wheelchair in the absence of public seats or rest stations. At the same time, it also creates more opportunities for companionship, interaction and heart-to-heart communication between the wheelchair user and family members, friends or wheelchair caregivers.

[0047] 3. Sitting: It can also be used by one person at ordinary times.
