Abstract
The utility model discloses a rear flat fork of an electric vehicle. The rear flat fork comprises a main connection rod. One end of the main connection rod is provided with a shaft which is connected with a frame of the electric vehicle, and the other end of the main connection rod is vertically provided with a motor support and a connection board. The motor support and the connection board are symmetrically arranged and in the same plane. A plurality of installation holes are formed in the motor support, and a frame rod is detachably connected on the connection board. A shaft hole is formed in the frame rod, and a rear shock absorber support is detachable connected at the end portion of the frame rod. The rear flat fork of the electric vehicle is simple in structure and easy to achieve. A split structure is utilized so that when a tire needs replacing or a motor needs repairing, only the frame rod is detached and a bolt of a fastening motor of the motor support is unscrewed, an end cover of the motor can be opened. Tires can be easily replaced and operation is convenient.
Description
Technical field
The utility model relates to a kind of battery-driven car, relates in particular to a kind of back chain stay of battery-driven car.
Background technology
Battery-driven car is driving with electric power in brief exactly, is the car of the energy with electric power.Along with the appearance of national energy-saving and emission-reduction policy, the use of battery-driven car is more and more universal.The back chain stay of existing battery-driven car mostly adopts the formula structure that is fixed as one, when the needs changing of tire, must pull down whole trailing wheel integral body, and the trailing wheel of battery-driven car is common and motor is one, when motor breaks down when needing repairing, motor integral body must be disassembled from car load, can keep in repair.
The utility model content
The purpose of this utility model is at the problems referred to above, and a kind of back chain stay of battery-driven car is provided, and adopts the formula structure that is fixed as one with the back chain stay that solves existing battery-driven car, causes tire changing, the problem of electrical machmary maintenance inconvenience.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of back chain stay of battery-driven car, comprise main connecting rod, one end of described main connecting rod is provided with the axle that is connected with the vehicle frame of battery-driven car, the other end of main connecting rod is vertically installed with motor bearing, connecting panel, described motor bearing and connecting panel symmetric arrangement, and be positioned at same plane, have a plurality of mounting holes on the described motor bearing, detouchable is connected with hack lever on the described connecting panel, has axis hole on the described hack lever, and its end detouchable is connected with the rear shock absorber bearing.
Further, described connecting panel is connected with hack lever by bolt, and described hack lever is connected with the rear shock absorber bearing by bolt.
Further, described motor bearing and main connecting rod are welded to connect, and described connecting panel and main connecting rod are welded to connect.
The beneficial effects of the utility model are, the back chain stay of described battery-driven car is simple in structure, be easy to realize, by adopting split type structure, when needs changing of tire or maintenance motor, only need hack lever is dismantled, and the bolt that the motor bearing tightens motor backed out, electric motor end cap can be opened, and replaceable tire, easy to operate.
Description of drawings
Fig. 1 is the structural representation of the back chain stay of a kind of battery-driven car of the utility model.
Among the figure:
1, main connecting rod; 2, axle; 3, connecting panel; 4, hack lever; 5, axis hole; 6, rear shock absorber bearing; 7, mounting hole; 8, motor bearing.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
Please refer to shown in Figure 1ly, Fig. 1 is the structural representation of the back chain stay of a kind of battery-driven car of the utility model; In present embodiment, a kind of back chain stay of battery-driven car, comprise main connecting rod 1, one end of described main connecting rod 1 is provided with the axle 2 that is connected with the vehicle frame of battery-driven car, the other end of main connecting rod 1 is vertically installed with motor bearing 8, connecting panel 3, described motor bearing 8 is welded to connect with main connecting rod 1, described connecting panel 3 is welded to connect with main connecting rod 1, described motor bearing 8 and connecting panel 3 symmetric arrangement, and be positioned at same plane, have a plurality of mounting holes 7 on the described motor bearing 8, and link to each other with motor by bolt, be connected with hack lever 4 by bolt on the described connecting panel 3, have axis hole 5 on the described hack lever 4, its end is connected with rear shock absorber bearing 6 by bolt.
Back of the present utility model chain stay, only needs hack lever 4 is disassembled by adopting split type structure when needs changing of tire or maintenance motor, and the bolt that motor bearing 8 is linked to each other with motor unloads, and can carry out, and is easy to operate, simply.
Above embodiment has just set forth groundwork of the present utility model and characteristic; the utility model is not limited by above-described embodiment; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
