Abstract: A wheel bracket mechanism for an electric wheelchair equipped with auxiliary wheels, which comprises a frame, a pair of drive wheel brackets, four pedestal assemblies, a pair of caster brackets, a pair of oscillating assembly and a pair of anti-tipping brackets. The frame is provide with a pair of castor brackets at the front end and a pair of anti-tipping brackets at the rear end thereof, a pair of drive wheel brackets are secured to the frame with a front end stretching ahead of it and located between the castor brackets and the anti-tipping brackets, and between the castor brackets and the drive wheel bracket disposed an oscillating assemblies, four pedestal assemblies equipped with cushioning blocks are disposed at both sides of the front and rear end of the frame respectively in pairs with located opposite to each other.

Abstract: A suspension structure for a front wheel assembly of a wheelchair generally includes struts of front wheel assemblies disposed at corresponding mounting brackets on the frame of the wheelchair. The struts will rotate upward about the corresponding jockey wheels when the jockey wheels are passing an obstacle, and meanwhile it will effect an uplift of the front end of the frame of the wheelchair. As a result, the gravity center of the user will be shifted backward so as to reduce the load on the jockey wheels, by this way, the jockey wheels may traverse the obstacle without difficulties. Furthermore, the suspension for the front wheel assembly of a wheelchair is simply structured so as to facilitate the assembly and reduce the production cost as well.

Abstract: A shell structure for elecrtrocar includes an outer shell covering on an inner shell, both on the outer and the inner shells are provided with plural coupling members, the coupling members of the outer shell can be quick coupled to that of the inner shell, in this way, the outer shell can be quick assembled and dismantled from the inner shell, in addition, since the shell is designed as being easy dismantable, so as to provide more shells with different colors and style to the users and allow them to change the shells as desired by themselves, and thus the shell of the present invention has high marketing value.

Abstract: A suspension structure for front wheel assembly of a wheelchair generally includes struts of front wheel assemblies disposed at corresponding mounting brackets of frame of the wheelchair. Such that the struts may rotate upward about the corresponding jockey wheels when the jockey wheels are passing a curb or other obstacle of the like, and meanwhile effects an uplift of the front end of the frame of wheelchair, as a result, the gravity center of the user move backward so as to reduce the load on the jockey wheels, by this way, the jockey wheels may traverse a curb or the like without difficulties. Furthermore, the suspension for front wheel assembly of a wheelchair is simple structured relative to conventional wheelchair so as to facilitate the assembly and reduce the production cost as well.
