When car body stability.
Detailed description of the invention
Attached drawing 1 is the overall structure diagram of the utility model；
Attached drawing 2 is the overall structure perspective view of the explosion of the utility model；
Attached drawing 3 is the connection sheet of the utility model and the partial enlargement structural representation of limit plate.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
As shown in Figure 1 and Figure 2, a kind of rear support frame of electric bicycle, including fixing seat 1, connection sheet 3 and support
Leg 2, the supporting leg 2 are inverted U bar structure, and two free ends of supporting leg 2 support ground, between two connection sheets 3
Away from being fixed on 2 upper ejector pin of supporting leg, and the lower section of fixing seat 1 is hingedly arranged in by connection sheet 3 for the supporting leg 2,
Connection sheet is hinged by articulated shaft 13 and fixing seat 1, further includes spring, one end of spring is connected to the hanging rod 14 on supporting leg
On, the other end is connected in fixing seat；The one side of the connection sheet 3 towards headstock is confined planes 5, and the confined planes 5 are flat
Face structure, adjacent tabs 3 are provided with limit plate 4 in the fixing seat 1, and the limit plate 4 is located at the front side of connection sheet 3, institute
Confined planes fitting limit plate setting is stated, the connection sheet 3 under the 4 limited support state of limit plate rotates, the limit plate 4 and limit
Plane 5 is arranged in parallel, and the confined planes 5 under holding state are fitted on limit plate 4.The utility model is limited by limit plate to be connected
Point contact or line contact are improved to face contact, effectively prevent the damage for using rear support frame for a long time by the rotation of contact pin,
Guarantee its normal use, promotes car body stability when electric bicycle is parked.
The fixing seat 1 includes the fixed plate 7 being arranged on the car body and the articulated slab 8 being arranged in below fixed plate 7, two institutes
It states connection sheet 3 and is respectively articulated with and be arranged on articulated slab 8, and two connection sheets 3 are to be located at the outside of articulated slab 8, institute
It states limit plate 4 and articulated slab 8 is integrally formed, and the limit plate 4 is bent to form outward for the front side wall of articulated slab 8, is bent
The top of limit plate 4 afterwards and fixed plate 7 are welded；It is integrally formed by the limit plate 4 with articulated slab 8, makes limit plate
Rigidity preferably, can extend the service life of limit plate 4.
As shown in attached drawing 2 and attached drawing 3, the side of limit plate 4 towards the connection sheet 4 is provided with elastic construction 10, described
For connection sheet 3 when rotating towards limit plate, namely when using support frame, the connection sheet 3 is slow by 10 elasticity of elastic construction
Punching.Support frame in the prior art, supporting leg with fixing seat are connect by spring assembly, to guarantee that it is quickly rotated
Movement elastic can generally impinge upon on limit plate when supporting leg rotates forward, so that limit plate is under frequent hit
