Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to an emergency mobile power supply. Background Technology

[0002] In emergency situations, emergency mobile power supplies, as portable power devices that provide power to various electronic devices, are widely used in natural disasters, public health emergencies, traffic incidents, and daily emergencies, playing a crucial role in providing reliable power in various emergency scenarios.

[0003] Currently, emergency portable power supplies are generally quite large and heavy due to factors such as power output, heat dissipation structure, protection structure, and circuit structure. Therefore, small and lightweight emergency portable power supplies have become a research hotspot. However, when using an internal combustion generator as an emergency portable power supply, it is difficult to resolve the contradiction between the need for small size and the need for high power generation performance. Specifically, compressing the overall size of the emergency portable power supply makes it difficult to properly arrange the air intake and exhaust components of the internal combustion generator, thus affecting the normal operation of the generator. For example, if the air intake pipe is too short, the air filter will be too close to the generator, or if the exhaust pipe is too short, the muffler will be too close to the generator. The air filter or muffler is easily affected by the heat of the generator, causing it to malfunction. Summary of the Invention

[0004] This invention provides an emergency portable power supply, which aims to solve the problem that existing technologies cannot reduce the mutual heat interference between devices in a small volume.

[0005] The present invention provides an emergency mobile power supply, comprising a housing having a second receiving cavity and a first receiving cavity, a generator disposed in the second receiving cavity, an exhaust mechanism connected to the generator, and an air intake mechanism;

[0006] The exhaust mechanism includes a muffler and an exhaust pipe; the muffler is disposed on the outer wall of the outer shell forming the first receiving cavity, the exhaust pipe passes through the second receiving cavity and the first receiving cavity, and the muffler is connected to the generator through the exhaust pipe.

[0007] The air intake mechanism includes an air filter and an air intake pipe. The air filter is arranged in the first receiving cavity, and the air filter is connected to the generator through the air intake pipe.

[0008] In some specific embodiments, the first receiving cavity is provided with a heat-insulating pipe, one end of which is connected to the second receiving cavity, and the other end of which forms an opening on the outer shell; the heat-insulating pipe is provided with the exhaust pipe.

[0009] In some specific embodiments, a gap is left between the heat insulation pipe and the exhaust pipe.

[0010] In some specific embodiments, the axial direction of the heat-insulating pipe is the same as the direction of the line connecting the second and first receiving cavities.

[0011] In some specific embodiments, the outer casing is provided with a first partition and a second partition;

[0012] The first partition divides the outer shell into the second receiving cavity and the first receiving cavity;

[0013] The second partition is disposed on the first partition, and the second partition divides the first partition into multiple installation spaces;

[0014] The exhaust pipe and the intake pipe are located in different installation spaces.

[0015] In some specific embodiments, the second receiving cavity is arranged below the first receiving cavity, and the volume of the second receiving cavity is smaller than the volume of the first receiving cavity.

[0016] In some specific embodiments, the muffler is arranged on the top of the housing.

[0017] In some specific embodiments, the outer casing has a plurality of ventilation holes arranged in an array on its wall surface.

[0018] In some specific embodiments, the housing is provided with a plurality of ventilation panel assemblies, the ventilation panel assembly including a ventilation panel, a baffle and a wing;

[0019] The ventilation plate is provided with a plurality of ventilation holes, and the baffle is used to shield the plurality of ventilation holes from the interior of the outer casing;

[0020] The bottom of the baffle is connected and fixed to the bottom of the ventilation plate, and the two sides of the ventilation plate are connected and fixed to the baffle through the wing plate. A gap is left between the baffle and the ventilation hole.

[0021] In some specific embodiments, the baffle includes a first guide section and a second guide section having an inclined guide surface;

[0022] The first guide section is arranged opposite to the ventilation plate, and the top height of the first guide section is higher than the top height of the ventilation plate;

[0023] The second guide section is inclinedly arranged at the bottom of the ventilation plate, and the bottom height of the second guide section is lower than the bottom height of the ventilation plate.

[0024] As can be seen from the above technical solutions, the present invention has the following advantages:

[0025] This embodiment provides an emergency mobile power supply. Since the generator is located in the second housing cavity, while the silencer is arranged on the outer wall of the outer shell where the first housing cavity is located, and the air filter is arranged in the first housing cavity, that is, the silencer and air filter are located in different cavities from the generator. Therefore, in specific implementation, on the one hand, the volume of the first cavity can be reduced by adjusting the size of the generator, thereby compressing the overall size as much as possible. On the other hand, the air filter and silencer can maintain a suitable distance from the generator, reducing the impact of the generator's heat on them, thereby ensuring the normal operation of the emergency mobile power supply. This effectively solves the problem that the prior art cannot reduce the mutual heat influence between devices in a small volume. Attached Figure Description

[0039] This invention provides an emergency mobile power supply to address the problem that existing technologies cannot reduce the mutual heat interference between devices in a small volume.

[0040] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0041] Please see Figures 1 to 6 The present invention provides an emergency mobile power supply, comprising: a housing 1 having a second receiving cavity 11 and a first receiving cavity 10, a generator (not shown in the figure) disposed in the second receiving cavity 11, an exhaust mechanism 2 and an air intake mechanism 3 connected to the generator;

[0042] The exhaust mechanism 2 includes a muffler 20 and an exhaust pipe 21; the muffler 20 is arranged on the outer wall of the outer shell 1 forming the first receiving cavity 10, and the exhaust pipe 21 passes through the second receiving cavity 11 and the first receiving cavity 10. The muffler 20 is connected to the generator through the exhaust pipe 21.

[0043] The air intake mechanism 3 includes an air filter 30 and an air intake pipe 31. The air filter 30 is arranged in the first receiving cavity 10 and is connected to the generator through the air intake pipe 31.

[0044] During the operation of this embodiment, sufficient fuel and air are pumped into the generator. The air enters the air filter 30 in the first receiving cavity 10 for filtration, and then enters the generator located in the first cavity through the intake pipe 31. After the gas and fuel enter the generator, the internal combustion engine converts the chemical energy of the fuel into mechanical energy, and then the mechanical energy into electrical energy. The mixture of fuel and air after combustion is discharged from the generator through the exhaust pipe 21, processed by the muffler 20, and then discharged to the outside, completing one cycle of air circulation.

[0045] As can be seen from the above working process, the generator is located in the second receiving cavity 11, while the air filter 30 and the silencer 20 are arranged in or outside the first receiving cavity 10. The generator and the air filter 30 and silencer 20 are located in different cavities, so the heat of the generator has a limited impact on the air filter 30 and silencer 20. With the generator being as small as possible (such as a short-shaft generator), this emergency mobile power supply can reduce the heat transfer between devices while meeting the requirement of small size.

[0046] Compared with existing technologies, it has the following advantages: First, it can reduce heat transfer between devices while keeping the overall size small. That is, the generator, air filter 30, and muffler 20 are arranged in separate chambers. The air filter 30 and muffler 20 are arranged in the second chamber, and the size of the generator is compressed as much as possible. This achieves the purpose of small overall size and low heat transfer, avoiding the situation in existing technologies where the air filter 30 and muffler 20 are placed close to the generator in order to compress the overall size, which leads to heat transfer between devices and affects normal operation. Second, it has a wide range of applications. That is, compared with the existing technology that uses battery cells, this embodiment uses an internal combustion generator. Internal combustion generators can work in various harsh environmental conditions. Its mechanical structure and working principle make it more resistant to the environment and fully meet the needs of emergency use.

[0047] In the application scenarios of this embodiment, the emergency mobile power supply can provide temporary power support when there is a power outage or insufficient power supply, ensuring the operation of critical equipment and systems. Applicable scenarios include, but are not limited to, applications during power outages in factories, supermarkets, medical facilities, traffic accidents, and disaster relief in natural disasters.

[0048] In one specific embodiment, such as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, a feasible structure of the outer shell 1 is further provided. The outer shell 1 includes an upper shell 1 with a first accommodation cavity 10 and a lower shell 1 with a second accommodation cavity 11. The upper shell 1 is used to carry an air filter 30 and a silencer 20, and the lower shell 1 is used to accommodate a generator. That is, the second accommodation cavity 11 is arranged below the first accommodation cavity 10, and the volume of the second accommodation cavity 11 is smaller than that of the first accommodation cavity 10. That is, the volume of the upper shell 1 is larger than that of the lower shell 1. An inverted "convex" character is formed between the upper shell 1 and the lower shell 1. Specifically in implementation, a structure with a smaller bottom and a larger top is formed, which can reduce the floor area and is beneficial for applications in emergency scenarios.

[0049] It should be noted that in addition to the cooperation of the upper shell 1 and the lower shell 1, the outer shell 1 can also be two shells arranged side by side in parallel, or other adjacent arrangement methods.

[0050] In one embodiment, as Figure 1 and Figure 2 shown, a feasible structure of the upper shell 1 is further provided. The upper shell 1 includes an upper frame body, a top plate, a first partition 13, a fuel tank 15, multiple first side plates, and a control board 16. The bottom surface of the upper frame body is fixedly provided with a first partition 13, the top surface of the upper frame body is fixedly provided with a top plate, two opposite side surfaces of the upper frame body are fixedly provided with first side plates, a side door and a ventilation plate assembly 4 with ventilation holes 400 are hinged on the first side plates, the remaining two side surfaces of the upper frame body are fixedly provided with a control board 16 and a fuel tank 15. The fuel tank 15 is provided with a fuel filling port 150 and a fuel pumping port 151, a fuel pumping pump chamber is installed on the fuel pumping port 151, and a wave-proof plate is provided in the fuel tank 15; the top plate, the first partition 13, the two first side plates, the control board 16 and the fuel tank 15 enclose to form the first accommodation cavity 10. Specifically in implementation, the user can pump the oil in the fuel tank 15 into the generator by using a fuel pump; the user can also open the side door on the first side plate to store items in the first accommodation cavity 10 or take them out from the first accommodation cavity 10; the user can also adjust the output of the generator on the control board 16.

[0051] In one embodiment, as Figure 1 and Figure 2 shown, a feasible structure of the lower shell 1 is further provided. The lower shell 1 includes a lower frame body, a bottom plate, a side door, a second side plate, and a third side plate. The bottom surface of the lower frame body is fixedly provided with a bottom plate, the top surface of the lower frame body is the first partition 13 of the upper shell 1, the side surface of the lower frame body is fixedly provided with a side door and a second side plate, a ventilation plate assembly 4 is also provided on the second side plate, and ventilation holes 400 are arranged in an array on the third side plate. The bottom plate, the side door, the second side plate, the third side plate, and the first partition 13 enclose to form the second accommodation cavity 11. Specifically in implementation, the user can open the side door to maintain the generator in the second accommodation cavity 11.

[0052] In one embodiment, such as Figures 3 to 6 As shown, in order to reduce heat transfer from the exhaust pipe 21, a heat-insulating pipe 12 is provided in the first receiving cavity 10. One end of the heat-insulating pipe 12 is connected to the second receiving cavity 11, and the other end of the heat-insulating pipe 12 forms an opening on the outer shell 1 for installing the muffler 20. That is, the heat-insulating pipe 12 connects the second receiving cavity 11 to the outside of the outer shell 1. An exhaust pipe 21 is provided inside the heat-insulating pipe 12 to form a double-layer pipe. In specific implementation, the heat from the exhaust pipe 21 will be blocked by the heat-insulating pipe 12, which can effectively prevent the heat from the exhaust pipe 21 from being transferred to the first receiving cavity 10, and prevent the heat from the exhaust pipe 21 from affecting other components.

[0053] In this embodiment, as Figure 5 and Figure 6 As shown, there is a gap between the heat insulation pipe 12 and the exhaust pipe 21. In specific implementation, a gap is formed between the two layers of pipes, which is equivalent to an additional heat insulation space. In the process of heat being transferred from the exhaust pipe 21 to the heat insulation pipe 12, more thermal resistance links need to be passed. That is, the heat must first pass through the gap before reaching the heat insulation pipe 12. Compared with the original heat insulation pipe 12, an additional heat insulation barrier is added, which greatly improves the heat insulation effect of the entire pipe system and prevents the heat from the exhaust pipe 21 from affecting other components.

[0054] In this embodiment, as Figure 5 and Figure 6 As shown, the axial direction of the heat insulation pipe 12 is the same as the direction of the line connecting the second receiving cavity 11 and the first receiving cavity 10. In specific implementation, the heat insulation pipe 12 is arranged in the direction of the line connecting the first receiving cavity 10 and the second receiving cavity 11. For example, when the first receiving cavity 10 and the second receiving cavity 11 are arranged horizontally, the heat insulation pipe 12 is arranged horizontally; or when the first receiving cavity 10 and the second receiving cavity 11 are arranged vertically, the heat insulation pipe 12 is arranged vertically. The purpose is to make the heat insulation pipe 12 form the shortest straight line between the generator and the muffler 20, and to make the space of the heat insulation pipe 12 within the outer casing 1 more compact.

[0055] In this embodiment, as Figure 5 and Figure 6 As shown, to avoid mutual heat interference between pipes, the outer casing 1 is provided with a first partition 13 and two second partitions 14; the first partition 13 is between the upper outer casing 1 and the lower outer casing 1 to separate the first receiving cavity 10 and the second receiving cavity 11, and the two second partitions 14 are provided on the first partition 13, which divides the first partition 13 into multiple installation spaces; the exhaust pipe 21 and the intake pipe 31 are located in different installation spaces. In specific implementation, the exhaust pipe 21 and the intake pipe 31 are arranged in two different spaces, and the heat or gas of the intake pipe 31 and the exhaust pipe 21 will not affect each other, reducing the mutual influence between components.

[0056] The first accommodating cavity 10 is divided into a first installation space and a second installation space by a second partition 14. The first partition 13 in the first installation space has a heat-insulated through hole for the exhaust pipe 21 to pass through. A heat-insulated enclosure wall is provided outside the heat-insulated through hole, forming the aforementioned heat-insulated pipe 12. The remaining space of the first installation space is for installing items. The user can open the first installation space through a side door hinged on the first side panel, where a kettle stand 19 can be installed. After placing the kettle on it, hot water can be boiled outdoors. The first partition 13 in the second installation space has an air filter through hole for the intake pipe 31 to pass through. The intake pipe 31 passes through the second installation space and is connected to the air filter 30. The second installation space also has an oil-water separator 17 and a coolant tank 18. The user can also open the second installation space through a side door hinged on the other side of the first side panel.

[0057] Based on the above embodiments, in a specific embodiment, such as Figure 1 , Figure 5 and Figure 6 As shown, a feasible structure for the ventilation panel assembly 4 is further provided. The ventilation panel assembly 4 includes a ventilation panel 40, a baffle 41, and a wing plate 42. The ventilation panel 40 has multiple ventilation holes 400, and the baffle 41 blocks the multiple ventilation holes 400 from the interior of the outer casing 1. The bottom of the baffle 41 is connected and fixed to the bottom of the ventilation panel 40, and the two sides of the ventilation panel 40 are connected and fixed to the baffle 41 through the wing plate 42. A gap is left between the baffle 41 and the ventilation holes 400, that is, the baffle 41, the wing plate 42, and the ventilation panel are connected and fixed to each other. With the cooperation of 40, a pocket-shaped structure is formed inside the ventilation plate 40. In specific implementation, the ventilation hole 400 can ensure that the outside of the outer shell 1 is connected to the first cavity or the second cavity, so that the heat in the first cavity or the second cavity can be dissipated to the outside of the outer shell 1. Furthermore, due to the setting of the baffle 41, after water droplets or debris from the outside enter the ventilation hole 400, they will be blocked by the baffle 41 in the pocket-shaped structure, preventing water droplets or debris from the outside from directly entering each cavity through the ventilation hole 400 and affecting the normal operation of the emergency mobile power supply equipment.

[0058] In this embodiment, as Figure 5 and Figure 6As shown, the baffle 41 includes a first guide section 410 and a second guide section 411 with an inclined guide surface. The first guide section 410 is arranged opposite to the ventilation plate 40, and the top height of the first guide section 410 is higher than the top height of the ventilation plate 40. The second guide section 411 is inclinedly arranged at the bottom of the ventilation plate 40, and the bottom height of the second guide section 411 is lower than the bottom height of the ventilation plate 40. In specific implementation, the first guide section 410 and the second guide section 411 can guide the airflow direction. For example, the airflow entering from outside the ventilation plate 40 will first be guided by the inclined surface of the second guide section 411, changing from horizontal to inclined upward. Then, the first guide section 410 guides the airflow to move vertically upward, forming a regular laminar flow and avoiding irregular airflow. Furthermore, the inclined surface of the second guide section 411 can accelerate the airflow and enhance the heat dissipation effect.

[0059] In one specific embodiment, such as Figures 1 to 6 As shown, a feasible structure for the muffler 20 is further provided. The muffler 20 is arranged on the top of the housing 1. After the muffler 20 is arranged on the top, on the one hand, the heat of the generator can be avoided from affecting the muffler 20, and on the other hand, the exhaust of each cylinder can be more evenly collected in the muffler 20, reducing exhaust interference and making the exhaust process of the engine more stable and efficient.

[0060] In one embodiment, such as Figures 1 to 6 As shown, a noise reduction protective cover 22 is provided outside the muffler 20. The noise reduction protective cover 22 is provided with heat dissipation holes, which can protect the normal operation of the muffler 20 and ensure that the heat is dissipated. The muffler 20 can be one of the absorption type muffler 20, reflection type muffler 20, or interference type muffler 20. As long as the muffler 20 can achieve the noise reduction function, those skilled in the art can consider choosing it. There will be no further details here.

[0061] In one embodiment, such as Figures 1 to 6 As shown, the muffler 20 is arranged on the top of the housing 1. After the muffler 20 is placed on the top, it will not be affected by the heat of the generator, ensuring that it can operate normally.

[0062] In one specific embodiment, such as Figure 5 and Figure 6 As shown, a feasible structure for an exhaust pipe 21 is further provided. The exhaust pipe 21 includes a rigid pipe, a pipe connector, and a flexible hose. The rigid pipe is installed in connection with the generator outlet, and the flexible hose is installed in connection with the muffler inlet. The rigid pipe and the flexible hose are connected by the pipe connector.

[0063] It should be noted that the pipe fittings can be compression fittings or clamp fittings. Any pipe fitting that can achieve the connection between soft and hard pipes can be considered by those skilled in the art, and will not be elaborated on here.

[0064] In one specific embodiment, the generator is an internal combustion generator, which is a short-shaft generator. The internal combustion generator can be one of a diesel generator, a gasoline generator, or a natural gas generator. Those skilled in the art can choose according to actual needs, which will not be elaborated on here.

[0065] In one specific embodiment, such as Figures 1 to 6 As shown, the outer shell 1 is also provided with automatic lifting legs 5. The automatic lifting legs 5 are arranged at the four corners of the outer shell 1 and are connected and fixed to the upper outer shell 1. In specific implementation, the automatic lifting legs 5 can adapt to various terrains, so that the emergency mobile power supply can work stably. The specific structure of the automatic lifting legs 5 can be found in the prior art (application number 202320671595.8), which will not be elaborated here.

[0066] In one specific embodiment, such as Figures 1 to 6 As shown, the outer casing 1 is also provided with a roller 6. The roller 6 is installed on the bottom of the outer casing 1 in a way that can be flipped up and down via a pivot. When the emergency power supply needs to be moved by sliding, the roller 6 can be flipped down and fixed so that it can slide by relying on the roller 6. When sliding is not needed, the roller 6 can be flipped up and fixed so that the bottom of the outer casing 1 is in contact with the ground. The specific structure of the roller 6 can be found in the prior art (application number 202011306726.X), which will not be described in detail here.

[0067] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.

[0068] Finally, it should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
