Description

Technical Field

[0001] The utility model relates to the field of generators, in particular to a hybrid generator. Background Art

[0002] The types and number of electronic products are increasing, and the demand for electricity is growing, but some electricity usage scenarios are not covered by the power grid. For example, when traveling in an RV, although the RV can supply a certain amount of electricity, it still cannot meet the needs of more electrical appliances. Existing hybrid generators can be used as mobile power sources, but their engines, generator sets, electronic components, etc. will generate a lot of heat. Although they are equipped with corresponding radiators, some of the heat still accumulates in the shell, which will accelerate the aging of the hybrid generator parts; some fuel may spill when refueling, such as gasoline, diesel and other fuels will evaporate into gas and accumulate in the shell, causing safety hazards. To solve this problem, some hybrid generators are equipped with exhaust fans on the shell to exhaust internal air and promote air circulation, but the exhaust fan still has many defects, such as increased cost and complex structure. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model proposes a hybrid generator, which realizes air circulation in the housing of the hybrid generator with a lower cost and simpler structure.

[0004] The utility model proposes a hybrid generator, including a housing and a battery pack, a generator set, an engine, an inverter and a control module integrated inside the housing, wherein the housing is composed of two parts, including an upper cover and a base, and the battery pack, the generator set, the engine, the inverter and the control module are integrated on the base. The housing is provided with an air inlet and an air circulation pipe, the exhaust pipe of the engine is arranged to intersect with the air circulation pipe, and the exhaust gas discharged from the exhaust pipe entrains the gas in the air circulation pipe and is discharged outside the housing, thereby driving the air to enter the housing through the air inlet, and then discharged from the air circulation pipe, completing the air circulation inside the housing.

[0005] Preferably, one end of the exhaust pipe away from the engine extends into the airflow circulation pipe, and a gap is set between the part of the exhaust pipe extending into the airflow circulation pipe and the inner wall of the airflow circulation pipe, so that the contact range between the exhaust gas discharged from the exhaust pipe and the gas in the airflow circulation pipe is maximized, thereby enabling the exhaust gas discharged from the exhaust pipe to drive the movement of the gas in the airflow circulation pipe to the greatest extent.

[0006] Preferably, a fixing bracket is further provided for fixing the relative position of the exhaust pipe and the airflow circulation pipe to prevent the exhaust pipe and the airflow circulation pipe from shifting.

[0007] Preferably, the cross-sections of the exhaust pipe and the air circulation pipe are both circular, so that the cross-sectional area of ​​the pipe body is maximized with the same amount of material used, and the portion extending into the air circulation pipe is coaxially arranged with the air circulation pipe to ensure aesthetics and thermal balance.

[0008] Preferably, the air circulation pipe is integrally formed with the shell to ensure aesthetics.

[0009] Preferably, the airflow circulation pipe is formed by extending the outer shell inwardly, and the airflow circulation pipe does not protrude from the outer shell surface, so that the outer surface of the shell is flat, which ensures aesthetics and prevents bumps.

[0010] Preferably, one end of the exhaust pipe away from the engine is connected in parallel with the airflow circulation pipe, and the connection between the exhaust pipe and the airflow circulation pipe forms a common pipe wall for the two, which can save materials to a certain extent.

[0011] Preferably, a protective net is provided inside the air circulation pipe to prevent foreign matter from entering the shell through the air circulation pipe.

[0012] Preferably, an anti-corrosion coating is provided on the inner wall of the airflow circulation pipe, thereby increasing the service life of the airflow circulation pipe.

[0013] The beneficial effect of the utility model is that the utility model cleverly utilizes the exhaust gas discharged by the engine to drive the air circulation inside the shell, which reduces the cost compared with the prior art, and at the same time, the structure is extremely simple, which is convenient for industrial design and mass production.

[0019] The utility model is further described in detail below with reference to the accompanying drawings, and specific implementation methods are given.

[0020] Example 1

[0021] like Figure 1 , Figure 2 As shown, a hybrid generator proposed by the utility model includes a housing 100 and a battery pack 200, a generator set 300, an engine 400, an inverter 500 and a control module 600 integrated in the housing 100. The housing 100 is composed of two parts, including an upper cover and a base, and the battery pack 200, the generator set 300, the engine 400, the inverter 500 and the control module 600 are integrated on the base. Both the battery pack 200 and the generator set 300 can output electric energy to the outside. When the generator set 300 outputs electric energy to the outside, under the control of the control module 600, the battery pack 200 supplies power to the starter motor of the engine 400, starts the engine 400, and the engine 400 drives the generator set 300 to generate electricity, and the inverter 500 adjusts the current and outputs it to the outside.

[0022] The housing 100 is provided with an air inlet 110 and an air circulation pipe 120. The exhaust pipe 410 of the engine 400 is arranged to intersect with the air circulation pipe 120. The exhaust gas discharged from the exhaust pipe 410 is discharged to the outside of the housing 100 along with the gas in the air circulation pipe 120, thereby driving the air to enter the housing 100 through the air inlet 110 and then be discharged from the air circulation pipe 120, completing the air circulation inside the housing 100. The air inlet 110 can be arranged at one end away from the air circulation pipe 120, so that the air flow range inside the housing 100 can be larger, thereby obtaining a better air circulation effect.

[0023] like Figure 3As shown, one end of the exhaust pipe 410 away from the engine 400 extends into the air circulation pipe 120, and a gap is set between the portion of the exhaust pipe 410 extending into the air circulation pipe 120 and the inner wall of the air circulation pipe 120, so that the exhaust gas discharged from the exhaust pipe 410 and the gas in the air circulation pipe 120 have the largest contact range, so that the exhaust gas discharged from the exhaust pipe 410 can drive the gas in the air circulation pipe 120 to move to the greatest extent, thereby improving the air circulation efficiency in the housing 100. Considering the manufacturing cost, the exhaust pipe 410 and the air circulation pipe 120 can be made into round pipes, thereby maximizing the cross-sectional area of ​​the pipe body under the same material usage. The part of the exhaust pipe 410 extending into the air circulation pipe 120 is coaxially arranged with the air circulation pipe 120. On the one hand, it has a certain aesthetic effect, and on the other hand, it makes the structure completely symmetrical. The thermal impact of the exhaust gas discharged from the exhaust pipe 410 on the pipe wall of the air circulation pipe 120 is balanced, and the exhaust gas will not corrode a part of the pipe wall of the air circulation pipe 120 for a long time, causing the pipe wall of the air circulation pipe 120 to be damaged. In order to fix the relative position of the exhaust pipe 410 and the air circulation pipe 120, a fixing bracket 121 can be provided. The fixing bracket 121 can fix the exhaust pipe 410 and the air circulation pipe 120 by means including but not limited to clamping, threaded connection, welding, etc.

[0024] In order to improve firmness, the air circulation pipe 120 is integrally formed with the shell 100, thereby reducing the joints of the hybrid generator, which can avoid damage on the one hand and improve the aesthetics on the other hand. Furthermore, the air circulation pipe 120 is formed by the shell extending inward, and the air circulation pipe 120 does not extend out of the shell surface, so that the outer surface of the shell 100 is flat, which can ensure aesthetics and prevent bumps, thereby avoiding damage to the hybrid generator.

[0025] Embodiment 2:

[0026] like Figure 4 As shown, one end of the exhaust pipe 410 away from the engine 400 is connected in parallel with the air circulation pipe 120, and the connection between the exhaust pipe 410 and the air circulation pipe 120 forms a common pipe wall 122 for the two, which can save materials to a certain extent and is also conducive to the compact shape design of the hybrid generator exhaust pipe 410.

[0027] The working scenes of the hybrid generator cover various complex outdoor environments such as deserts, Gobi, and forests. Therefore, a protective net is arranged in the air circulation pipe 120 to prevent foreign objects such as sand, dirt, and branches, as well as animals such as insects, snakes, and rats from entering the interior of the shell 100 through the air circulation pipe 120.

[0028] The exhaust gas discharged by the engine 400 contains sulfate substances, high molecular substances, etc., and has a high temperature, which will corrode the wall of the airflow circulation pipe 120. In order to extend the service life of the wall of the airflow circulation pipe 120, an anti-corrosion coating is provided on the inner wall of the airflow circulation pipe 120. The anti-corrosion coating can be attached to the inner wall of the airflow circulation pipe 120 by methods including but not limited to spraying, electroplating, deposition, etc., thereby improving the service life of the airflow circulation pipe 120.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
