Description

Technical Field

[0001] This utility model belongs to the technical field of integrated housing devices for automobile range extenders, specifically relating to an integrated housing for a range extender. Background Technology

[0002] Currently, range extenders consist of an engine and a generator connected together by bolts. The engine and generator have separate housings, resulting in numerous parts, a complex structure, high costs, and a large system size. This makes them unsuitable for vehicle layout and requires a considerable amount of time and multiple tools for disassembly. Summary of the Invention

[0003] The purpose of this utility model is to integrate the range extender engine and generator housing into a single unit, reducing the number of system components, simplifying the system structure, lowering costs, shortening the system's axial length for easier vehicle layout, and allowing for quick and easy disassembly by personnel, reducing the need for auxiliary tools. The technical solution is as follows:

[0004] An integrated housing for a range extender, characterized in that: it includes an upper housing 1 and a lower housing 2, with a generator mounting housing 3 connected to the front end of the upper housing 1 and the front end of the lower housing 2, the generator mounting housing 3 being divided into two half-housings, the two half-housings being respectively connected to the front ends of the upper housing 1 and the lower housing 2, a plurality of crankshaft bearing holes 5 being evenly distributed in a horizontal row at the middle of the inner surface of the upper housing 1 and the lower housing 2, a bidirectional oil seal seat 6 being provided at the inner edge of the front end of the upper housing 1 and the lower housing 2, a plurality of generator stator mounting bolt holes 7 being connected to the four edges of the inner rear surface of the lower half-housing, a plurality of generator stator mounting bolt holes 4 being connected to the four edges of the inner rear surface of the upper half-housing, and the lower inner lower surface of the lower half-housing being planar.

[0005] The beneficial effects of this utility model are as follows: the range extender engine and generator housing are integrated into one unit, reducing the number of system parts, the system structure is simple and the cost is low, the axial length of the system is shortened, which is conducive to the overall vehicle layout, and the staff can quickly disassemble it at any time, reducing the need for staff to use auxiliary tools.

[0010] Reference Figures 1-3 The integrated housing for a range extender is characterized by comprising an upper housing 1 and a lower housing 2. A generator mounting housing 3 is connected to the front end of the upper housing 1 and the front end of the lower housing 2. The generator mounting housing 3 is divided into two half-housings, which are respectively connected to the front ends of the upper housing 1 and the lower housing 2. A plurality of crankshaft bearing holes 5 are evenly distributed in a horizontal row at the middle of the inner surface of the upper housing 1 and the lower housing 2. A bidirectional oil seal seat 6 is provided at the inner edge of the front end of the upper housing 1 and the lower housing 2. A plurality of generator stator mounting bolt holes 2 7 are connected to the four edges of the inner rear surface of the lower half-housing. A plurality of generator stator mounting bolt holes 1 4 are connected to the four edges of the inner rear surface of the upper half-housing. The lower inner lower surface of the lower half-housing is flat.

[0011] In use, first place the crankshaft in the crankshaft bearing hole 5 on the upper housing 1, then cover the upper housing 1 with the upper housing 2 and clamp the crankshaft bearing hole 5 in the crankshaft bearing hole 5. Then tighten the upper housing 1 and the lower housing 2 with bolts. At the same time, the bidirectional oil seal 6 on the front and rear surfaces of the upper housing 1 and the lower housing 2 seals the inner cavity between the upper housing 1 and the lower housing 2. The bidirectional oil seal 6 can also isolate the engine oil from the generator cooling oil. Then place the engine in the motor mounting housing 3. Finally, fix the motor stator to the stator mounting bolt hole 1 4 and the generator stator mounting bolt hole 2 7 with bolts.

[0012] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
