Abstract
The utility model provides an integrally formed type backrest support frame. The integrally formed type backrest support frame comprises a back cushion base plate, a connection support frame and a backrest connection plate and is characterized in that the back cushion base plate, the connection support frame and the backrest connection plate are integrally formed with no connection gap. The back cushion base plate is placed at the upper end of a whole body, and fixing installation holes are arranged in the back cushion base plate. The connection support frame is placed in the middle position of the whole body, and strengthening ribs are arranged on the connection support frame. The backrest connection plate is placed at the lower end of the whole body, and fixing installation holes are arranged in the backrest connection plate. The integrally formed type backrest support frame is stamped and formed at one time by a grinding tool in a production process, so no connection gap is formed, and technological operation of the production is simplified. Due to the fact that the integrally formed type backrest support frame is formed at one time, and no connection gap is formed, and the problems that cracking and corrosion with damping and the like of a gap caused by untight welding are solved, so potential safety hazards caused by a destroyed back frame are avoided. According to the integrally formed type backrest support frame, the strengthening ribs which are in a flat structure are arranged at a position connecting the support frame, so the bearing capacity of the backrest support frame is improved.
Description
Technical field
The utility model relates to the electric accessory motor field, relates in particular to a kind of back rest support.
Background technology
Along with the development of science and technology, the quickening of people's rhythm of life, bicycle can not satisfy people to the requirement of speed, but the automobile floor area is large, and some is local and inapplicable, so Electrical Bicycle arises at the historic moment, battery-driven car is exactly take electric power as driving in brief, the car take electric power as the energy.First battery-driven car produced in 1834, and it is driven by DC machine.Even to this day, great variety has occured in battery-driven car, and type is also varied.For manned loading convenience, Electrical Bicycle after-frame position is provided with rear connection bracket, but rear connection bracket now all is that back cushion base plate, connection bracket, backrest connecting strap are welded, complex structure and weld are subjected to cargo sweat easily, and support is in case the loosening life security that can directly threaten the occupant of corrosion.
Summary of the invention
According to above technical matters, the utility model provides a kind of integrate shaped type back rest support, comprise back cushion base plate, connection bracket, backrest connecting strap, it is characterized in that back cushion base plate, connection bracket, backrest connecting strap are one-body molded, do not connect the slit, described back cushion base plate is positioned at whole upper end, the above is provided with the fixed installation hole, and described connection bracket is positioned at whole midway location, and described connection bracket is provided with reinforced rib, described backrest connecting strap is positioned at whole lower end, and the above is provided with the fixed installation hole.
Reinforced rib on the described connection bracket is flat structure.
The beneficial effects of the utility model are: by the disposable punch forming of mould, without any connecting the slit, reduced the technological operation of producing when the utility model is produced.Because the one-body molded slit that do not connect of the utility model has solved because welding does not sternly wait the slit of causing to ftracture, be subjected to the problems such as cargo sweat, thereby has avoided damaging the potential safety hazard that occurs because of after-frame.The utility model is provided with reinforced rib at the connection bracket place and reinforced rib is flat structure, has strengthened the weight capacity of back rest support.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
According to shown in Figure 1, the utility model is further specified:
Such as Fig. 1, back cushion base plate-1, connection bracket-2, backrest connecting strap-3, reinforced rib-4,
Embodiment 1
The utility model is generated by a mould during production, back cushion base plate 1 is positioned at whole upper end, the mounting hole of offering in the above can be fixed on the utility model on the vehicle body, connection bracket 2 is positioned at whole midway location, and connection bracket 2 is provided with two reinforced ribs 4, is provided with the space between the reinforced rib 4, and backrest connecting strap 3 is positioned at whole lower end, the above offers the fixed installation hole, and the mounting hole of the mounting hole on the back cushion base plate 1 and backrest connecting strap 3 firmly has been fixed on novel back rest support on the vehicle body.
During use, mounting hole the utility model by the mounting hole on the back cushion base plate 1 and backrest connecting strap 3 firmly has been fixed on the battery-driven car after-frame, then the people can directly be sitting on the after-frame, the reinforced rib 4 of connection bracket 2 plays a role, can support the stable of after-frame, the people can directly lean against on the back cushion base plate 1, can not shake, and has guaranteed the safety of passenger.
