[0056] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] like Figures 1 to 3 As shown, the present invention provides a box structure, comprising:

[0058] A box structure for placing a hybrid power system, comprising: a box, a hot space air inlet 1, a hot air outlet 2, a cold space air inlet 3, a hot space exhaust device 4 and a cold space exhaust device 5, wherein:

[0059] A box body, wherein the box body is divided into a hot space area 7 and a cold space area 8 by a heat insulation layer 9, and a connecting channel 6 for a first device in the hot space area 7 and a second device in the cold space area 8 is provided on the heat insulation layer 9, for example, it can be a bearing channel, etc.;

[0060] Through the hot space air inlet 1, hot air outlet 2 and hot space exhaust device 4 arranged on the box body, external gas can enter the hot space area 7 from the hot space air inlet 1 and be discharged from the hot space exhaust device 4, thereby ensuring the air required for engine combustion in the hot space area 7 and enhancing the discharge of internal heat to ensure the ambient temperature of the hot space area 7;

[0061] Similarly, through the cold space air inlet 3 and the cold space exhaust device 5 set on the box body, external gas can enter the cold space area 8 from the cold space air inlet 3 and be discharged from the cold space exhaust device 5, thereby enhancing the discharge of internal heat and ensuring the ambient temperature of the cold space area 8.

[0062] The hybrid power system includes: a first device and a second device;

[0063] Preferably, the hot space area 7 can be used to arrange first equipment such as an engine, and the cold space area is used to arrange second equipment such as an output motor, and a connecting channel between the engine and the output motor is provided on the thermal insulation layer 9.

[0064] In this embodiment, the box space is divided into a hot space area 7 and a cold space area 8, wherein the hot space area 7 can be used to place equipment with a higher temperature, such as an engine, etc., because the engine requires gas, so the overall temperature of the hot space area is relatively high; the cold space area 8 can be used to place equipment with a lower temperature, such as a motor, and the heat insulation layer can ensure heat isolation to prevent the high temperature of the hot space area from being conducted to the cold space area, thereby affecting the ambient temperature of the cold space area, and further affecting the equipment with a lower temperature, such as the motor placed in the cold space area.

[0065] For example, if the box is rectangular, the box includes six wall panels, namely a top wall, a bottom wall, and four side walls connected between the top wall and the bottom wall;

[0066] Here, the material of the box body can preferably be a heat dissipation or heat-conducting material, such as aluminum, aluminum-magnesium alloy, aluminum-lithium and other materials that are easy to transfer and dissipate heat; specifically, 7075 aluminum material can be used to make the box body; the outer surfaces of each wall panel of the box body can be set to heat dissipation teeth or heat dissipation grilles and other structures to increase the heat dissipation area, improve the strength of the box body, and reduce the weight of the box body.

[0067] More preferably, the heat insulation layer 9 can be made of non-heat-conductive and high-temperature resistant materials, such as alumina fibers and the like.

[0068] More preferably, sound insulation and / or heat transfer material 10 is also provided on the inner wall of the wall panel of the box body, and sound insulation and heat transfer materials can also be arranged at each air inlet and exhaust port to facilitate sound insulation and heat dissipation; the sound insulation and noise reduction layer formed by the sound insulation material can minimize the conduction and reflection of noise, thereby reducing the noise level.

[0069] like Figure 1 As shown, the hot space air inlet 1 is arranged on the wall plate of the box body of the hot space area 7, and the hot space air inlet 1 is provided with a guide vane 11 around it, and the guide vane 11 is located in the hot space area; preferably, the hot space air inlet 1 is in close contact with the air inlet of the engine and some remaining space is left:

[0070] Specifically, part of the external air entering from the hot space air inlet 1 enters the engine through the air inlet of the engine, and the other part enters the hot space area through the guide vane 11 to dissipate heat for the equipment in the hot space area 7; it should be noted that the close proximity mentioned here means that the hot space air inlet 1 is very close to the air inlet of the engine, but there is no contact and mechanical connection, which is convenient for noise reduction and subsequent mechanical maintenance;

[0071] Preferably, the guide vane 11 is in a bell-mouth shape, the small mouth of the bell-mouth is connected to the air inlet of the hot space, and the large mouth of the bell-mouth is away from the air inlet of the hot space, so as to facilitate drainage and noise reduction.

[0072] Preferably, the hot space air inlet 1 may be integrated with a filter to filter impurities and particles in the air and protect internal components such as the engine;

[0073] A hot air outlet 2 is provided on the wall plate of the box body in the hot space area, and the hot air outlet 2 is in close contact with the exhaust port of the engine;

[0075] Preferably, a cover plate is also provided on the hot gas exhaust port to prevent dust. When in use, the exhaust port of the engine can directly discharge the high-temperature gas to the outside of the traffic or transportation equipment through the hot gas exhaust port; the hot gas exhaust port can be set on the box wall panel at the top of the hot space area, which helps to prevent the backflow of high-temperature gas generated by combustion, thereby protecting the engine from damage.

[0076] More preferably, the cover on the hot gas exhaust port can be set as an automatic exhaust cover. The benefits of the automatic exhaust cover are mainly reflected in improving safety, optimizing performance, and facilitating maintenance and management. The automatic exhaust cover adopts an intelligent control system, which can automatically adjust the opening and closing degree and exhaust volume of the exhaust port according to the actual working state of the engine and external environmental conditions to achieve precise control.

[0077] Specifically, a controller can be set in the cold space area, and a temperature sensor can be set in the exhaust gate of the engine in the hot space area. The controller can sense the temperature in the exhaust box through the temperature sensor. When the temperature rises to a certain level, the controller can send an instruction to the motor that controls the operation of the cover. This motor can open the exhaust cover through the transmission device to allow exhaust gas to be discharged.

[0078] In addition, the controller can sense through the temperature sensor that the temperature in the exhaust box drops to a certain level or when the user manually operates it, the controller can issue a command again, and the motor closes the exhaust cover through the transmission device to maintain the sealing of the exhaust box.
