Abstract
The invention discloses a coaxial centrally-mounted driving assembly for an electric vehicle with a built-in controller. The coaxial centrally-mounted driving assembly comprises a driving assembly shell and a shell sealed end cover, wherein a motor middle axle hole, a waterproof sealed chamber, a bearing chamber and a control circuit board chamber are formed on the shell sealed end cover sequentially; a control circuit board is arranged in the control circuit board chamber; the radiating surface of each power amplifier tube of the control circuit board is fastened with the surface of the shell sealed end cover so that the shell sealed end cover is used as the radiating surface of each power amplifier tube; and the shell sealed end cover is hermetically fastened with the end face of the driving assembly shell. In the driving assembly, the control circuit board is sealed in the driving assembly shell and the shell sealed end cover of the driving assembly is used as the radiating surface of each power amplifier tube, so that the radiating problem of the power amplifier tubes can be solved. The driving assembly has the advantages of small volume, compact structure, watertightness and short circuit prevention. The driving assembly is not provided with an external controller so as to reduce the occupied space in a vehicle frame.
Description
Technical field
The present invention relates to the coaxial middle centrally-mounted driving assembly of a kind of middle axis drive motor assembly, especially electric vehicle.
Background technology
What existing electric bicycle (Moped Scooter) was comparatively commonly used is low speed rear-wheel hub motor, this electric bicycle does not have at battery, when manpower drives, because the rotation of bicycle rear need overcome the inductance resistance and the complete vehicle quality resistance of motor, therefore the rider relatively requires great effort, and the time of bicycle art skating obviously shortens.In order to overcome this defective, people have proposed a kind of electric bicycle with coaxial mid-motor, motor is arranged on the mid-five-way of vehicle frame position (being called the setting of motor middle), and motor is unsettled to be contained on the axis, pedal is arranged on two ends of motor axis, and motor axis and trailing wheel are the chain transmission.Can select electronic respectively during cycling or the pedal driving, also can electronic simultaneously and pedal driving.Because do not had the inductance resistance of motor when the bicycle art skating, the art skating time is longer, in this case, the rider is comparatively laborsaving.But, existing middle axis drive motor assembly, its motor and controller are splits, leave the position of controller on cycle frame, and controller adopts outer connecting line to be connected with motor.The one,, on cycle frame, leave the position of controller, hindered the design instructions for use of the light compactness of electric bicycle, the 2nd,, wiring place of outer connecting line can produce corrosion and short circuit because of the rainwater problem.Generally speaking, the control circuit of controller has power tube, needs heat radiation during power tube work, and controller must be provided with radiator structure, so prior art can't be integral formula with controller and design of electrical motor.
Summary of the invention
Problem to be solved by this invention is the defective that the axis drive motor assembly existed during overcoming existing electric bicycle used, and a kind of coaxial middle centrally-mounted driving assembly of electric vehicle of built-in controller is provided.The controller of drive motors assembly (control circuit board) is sealed in the drive motors assembly shell, forms control circuit and motor integrated structure, can effectively solve motor and control circuit volume and waterproof and short circuit problem.
Centrally-mounted driving assembly during the electric vehicle of built-in controller of the present invention is coaxial, comprise and drive assembly shell and body seal end cap, the body seal end cap is circular, rise by the body seal end cap outside, have motor axis axis hole, waterproof sealing chamber and bearing chamber on the shell end cover successively, motor axis axis hole, waterproof sealing chamber and bearing chamber are cylindrical hole; It is characterized in that: have the control circuit board chamber in the inboard of shell end cover (sealing surface side); The indoor control circuit board that is provided with of control circuit board; Control circuit board is provided with lead screw bar hole in each power tube position, the corresponding therewith corresponding lead screw silk hole that has in the control circuit board chamber of shell end cover; Pass the lead screw bar hole of control circuit board with lead screw, screw with the lead screw silk hole on the body seal end cap, the radiating surface and the body seal end cap face of each power tube of control circuit board is fastening, the body seal end cap as the power tube radiating surface, can be solved the power tube heat dissipation problem.The body seal end cap is fastening with the face seal of driving assembly shell end.
Centrally-mounted driving assembly during the electric vehicle of built-in controller of the present invention is coaxial, control circuit board (controller) are sealed in and drive in the assembly shell, will drive assembly body seal end cap as the power tube radiating surface, can solve the power tube heat dissipation problem.It is little to drive the assembly volume, compact conformation, and waterproof is prevented short circuit.No external controller has reduced taking up room at vehicle frame.

Fig. 2 is the body seal end cap and the control circuit board perspective view of the coaxial middle centrally-mounted driving assembly of the electric vehicle of built-in controller of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is elaborated.
Embodiment: as shown in Figure 1, 2, centrally-mounted driving assembly during the electric vehicle of built-in controller is coaxial, comprise and drive assembly shell and aluminum shell end cover 1, the body seal end cap is circular, rise by the body seal end cap outside, have motor axis axis hole 2, waterproof sealing chamber 3 and bearing chamber 4 on the shell end cover successively, motor axis axis hole, waterproof sealing chamber and bearing chamber are cylindrical hole; Have control circuit board chamber 5 in the inboard of shell end cover; The indoor control circuit board 6 that is provided with of control circuit board, the substrate of control circuit board 6 is an annular; The substrate of control circuit board is provided with lead screw bar hole 7 in each power tube position, the corresponding therewith corresponding lead screw silk hole 8 that has in the control circuit board chamber of shell end cover; Pass the lead screw bar hole of control circuit board with lead screw, screw with lead screw silk hole on the body seal end cap, the radiating surface and the body seal end cap face of each power tube 9 of control circuit board is fastening.The body seal end cap is fastening with the face seal of driving assembly shell end.
