Description
Technical Field
The utility model relates to an increase journey ware, especially an external journey ware that increases of rectifier bridge.
Background
At present, when the battery electric quantity of the range-extended electric low-speed four-wheel vehicle is sufficient, the power battery drives the motor to provide the driving power requirement of the whole vehicle, and at the moment, the range extender does not participate in the work. When the electric quantity of the battery is consumed to a certain degree, the range extender is started, and the range extender provides energy for the battery to charge the power battery. When the electric quantity of the battery is sufficient, the range extender stops working again, and the battery drives the motor to drive the whole vehicle. In the existing range extender, the rectifier bridge of important parts is installed inside a controller shell, when large current passes through the range extender, the temperature rise of the range extender is fast, the temperature is high, the integral temperature of the rectifier bridge rises, the load is too large, and the rectifier bridge can be burnt out seriously.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an external journey ware that increases of rectifier bridge that can effectively carry out the heat dissipation to the rectifier bridge.
The utility model aims at realizing through such technical scheme, an external journey ware that increases of rectifier bridge, including engine and generator one side is provided with the rectifier bridge, the rectifier bridge passes through installing support and motor cover outer wall connection the rectifier bridge bottom is provided with the radiator.
In order to further improve the heat dissipation effect, the engine comprises a left crankcase and a right crankcase, and a crankshaft is arranged in the left crankcase and the right crankcase; the generator comprises a stator assembly and a rotor assembly connected with a crankshaft, a fan connected with the rotor assembly is arranged on one side of the rotor assembly, a motor cover for covering the rotor assembly is arranged outside the rotor assembly and connected with a right crankcase, a strip-shaped air outlet is formed in the motor cover and corresponds to the radiator.
In order to save space and facilitate heat dissipation of the controller, the controller is arranged on the outer side of the left crankcase and is connected with the outer wall of the left crankcase through a connecting support.
Since the technical scheme is used, the utility model has the advantages of simple structure, use reliably, the overall arrangement is ingenious, adopt it to effectively dispel the heat to the rectifier bridge, improved the operating stability of rectifier bridge, guaranteed the reliability of work, prevented the rectifier bridge because the high temperature and the damage that leads to.
Drawings
The drawings of the utility model are as follows:
fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a left side view of FIG. 1;
fig. 3 is a top view of the present invention.
Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the accompanying drawings, but the present invention is not limited to these embodiments, and any modifications or substitutions in the basic spirit of the embodiments will still fall within the scope of the present invention as claimed in the appended claims.
Example 1: as shown in fig. 1, 2 and 3, the external range extender comprises an engine 1 and a generator, wherein a rectifier bridge 2 is arranged on one side of the generator, the rectifier bridge 2 is connected with the outer wall of the generator through a mounting bracket 3, and a radiator 4 is arranged at the bottom of the rectifier bridge 2.
In order to further improve the heat dissipation effect, the engine 1 includes a crankcase 5 and a crankcase 6, and a crankshaft is disposed in the crankcase 5 and the crankcase 6; the generator comprises a stator assembly and a rotor assembly 7 connected with a crankshaft, a fan 8 connected with the rotor assembly 7 is arranged on one side of the rotor assembly 7, a motor cover 9 covering the rotor assembly 7 is arranged outside the rotor assembly 7, the motor cover 9 is connected with a right crankcase 6, a strip-shaped air outlet 10 is arranged on the motor cover 9, and the strip-shaped air outlet 10 corresponds to the radiator 4.
The utility model discloses in, the heat that 2 work of rectifier bridge produced carries out the heat exchange through the radiator, and the wind that the rotation of fan drove simultaneously outwards blows off through the bar air outlet, dispels the heat to the radiator, has just so reduced the temperature of rectifier bridge, has guaranteed rectifier bridge's job stabilization nature.
Further, in order to save space and facilitate heat dissipation of the controller, a controller 11 is disposed outside the left crankcase 5, and the controller 11 is connected to the outer wall of the left crankcase 5 through a connecting bracket 12.
