Description

TECHNICAL FIELD

[0001] The present application relates to a range-extending hybrid system, in particular to a combined support fixed with an engine. BACKGROUND

[0002] In the air-cooled two-stroke hybrid system, the magneto needs to be fixed to generate power, the cooling fan needs to be fixed to cool the hybrid system, and the cooling wind needs to be guided by the interface fairing. The prior art center has a combined support fixed with an engine, which fixes the magneto and the cooling fan and interfaces with a fairing. However, the combined support fixed with the engine has the following defects: the magneto and the engine generate a certain torque during their own operation, and the hybrid new system is a cantilever structure when fixed externally, the distance between the shock pads is too close, and the length of the shock pads is higher than that of the fan, so that the structure is not ideal in terms of bending resistance and torsion resistance when installed on the whole machine. In addition, the shock pads are arranged between the two cooling fans, which easily blocks the air inlet of the cooling fan when installed externally. SUMMARY

[0003] Therefore, the present application provides a combined support fixed with an engine to solve the problem of the prior art that the whole machine is not ideal in terms of bending resistance and torsion resistance.

[0004] The present application provides a combined support fixed with an engine, which comprises an engine support installed at a fixed end of the engine and a fan mounting bracket installed at an output end of the engine, a shock pad is installed on the engine support, a cooling fan is installed on the fan mounting bracket, and the cooling fan and the shock pad are installed on both sides of the engine, respectively.

[0005] Preferably, the engine support comprises a support surface, a first through hole for discharging cold air from the surface of the crankcase is arranged at the center position of the support surface, and a plurality of first fixing holes are uniformly arranged on the support surface around the first through hole.

[0006] Preferably, a plurality of support feet are arranged on the outer side of the support surface, the support feet extend away from the first through hole, and the shock pad is fixedly arranged on the support feet.

[0007] Preferably, the output end of the engine is connected with the stator and the rotor of the magneto through a magneto stator support and a magneto rotor support, respectively.

[0008] Preferably, the magneto stator support comprises a magneto stator fixing portion and a flange portion fixedly connected with the magneto stator fixing portion.

[0009] Preferably, the magneto stator fixing portion is inwardly contracted to form a circular arc-shaped support surface, and the flange portion is fixedly connected with one end of the circular arc-shaped support surface away from the magneto stator fixing portion.

[0010] Preferably, the fan mounting frame comprises a connecting portion and fan mounting portions symmetrically arranged on both sides of the connecting portion.

[0011] Preferably, the magneto rotor support comprises a rotor support body and an inner hole arranged at the center of the rotor support body, and one end of the rotor support body is provided with a fixing table, and the fixing table is provided with a plurality of fourth fixing holes.

[0012] Preferably, a fairing is fixedly connected between the fan mounting frame and the engine support.

[0013] Preferably, the fairing is internally provided with two inner walls, and the two inner walls divide the inside of the fairing into three spaces, namely, air ducts arranged on both sides and an engine passage arranged in the middle of the air ducts.

[0014] The application has the advantages and positive effects that: 1. The cooling fan and the damping pad originally mounted on the same side are mounted on both sides of the engine through the engine support and the fan mounting frame, so that the engine support has sufficient space to extend its supporting surface, thereby increasing the supporting surface and the distance between the damping pads, and improving the bending and torsion resistance of the overall structure; 2. By changing the structure of the magneto stator support, the fan mounting frame is arranged between the engine and the magneto, so that the cooling fan is mounted between the cylinder of the engine and the magneto, thereby reducing the length of the entire system, i.e. reducing the length of the entire system as a cantilever to reduce the torque; 3. Since the fan mounting frame is in front and the engine support is in back, the fairing is designed as two parts in front and back and is fixed on the fan support and the engine support respectively, so as to improve the stability of the fairing in the hybrid power system; 4. The fairing is designed as two parts in front and back, an inner wall can be designed in the fairing, and a separate air duct is formed for each cylinder block, thereby improving the cooling efficiency of the cooling fan.

[0028] To better understand the present invention, the present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0029] like Figure 1 As shown, the existing air-cooled two-stroke hybrid power system includes a magneto 8a and an engine 5a. The magneto 8a is connected to the engine 5a. Specifically, the stator and rotor of the magneto 8a are connected to the engine 5a through a magneto stator bracket 6a and a magneto stator bracket 7a, respectively. The stator and rotor of the magneto 8a are connected to the magneto stator bracket 6a and the magneto rotor bracket 7a, respectively. The magneto stator bracket 6a is divided into upper and lower halves and is fixed to the crankcase of the output end 5a2 of the engine 5a by clamping. The magneto rotor bracket 7a is connected to the flywheel of the engine 5a.

[0030] Further, the mounting bracket 3a fixed to the fixed end 5a1 of the engine 5a is provided with the cooling fan 2a at the outer side edge thereof, and the mounting bracket 3a at the inner side of the cooling fan 2a is provided with the damping pad 1a; the inner side of the mounting bracket 3a is provided with the fairing 4a; further, the fairing 4a is divided into two halves and is mounted from the two sides of the cylinder block respectively, and one end of the fairing 4a is fixed to the fan mounting bracket 3a and the other end thereof is tightly embraced to the magneto stator bracket 6a to be fixed.

[0031] In the prior art, the damping pads 1a are arranged at the inner side of the cooling fan 2a, so that the distance between the damping pads 1a is too close, and in order to avoid the influence of external equipment on the cooling fan 2a, the thickness of the damping pad 1a in the transverse direction is greater than the thickness of the cooling fan 2a; the engine 5a and the magneto 8a generate certain torque during their operation, and the hybrid new system is a cantilever structure when it is fixed to the outside, so that the bending resistance and the torsion resistance of the structure when it is mounted to the whole machine are not ideal; in addition, the damping pads 1a are arranged between the two cooling fans 2a, and when the hybrid new system is fixed to the outside, the air inlet of the cooling fan 2a is easily blocked.

[0032] Meanwhile, one end of the fairing 4a is connected to the magneto stator bracket 6a in a tightly embracing manner, but since the thickness of the fairing 4a is relatively thin, it is difficult to generate sufficient embracing force when it is tightly embraced (if the embracing force is too large, the fairing will be damaged), so that the fixing manner at this position is not reliable; and the fairing 4a is divided into two halves and is mounted from the two sides of the cylinder block respectively, and since the structure of the cylinder block is large at the upper end and small at the lower end, this structure is destined to be unable to provide a separate cooling air duct for each cylinder block, and the use efficiency of the cooling fan 2a is low.
