[0002] In emergency situations, emergency mobile power supplies, as a portable power supply device that provides power support for various electronic devices, are widely used in natural disasters, public health events, traffic incidents and daily emergencies, providing reliable power in a variety of emergency scenarios and playing a key role.

[0003] In current technology, since the power output, heat dissipation structure, protection structure, circuit structure, etc. will make the emergency mobile power supply larger in size and weight, emergency mobile power supplies with small size and light weight have become a research hotspot. However, when using an internal combustion generator as an emergency mobile power supply, it is difficult to resolve the contradiction between the small size requirement and the high power generation performance requirement. That is, compressing the overall volume of the emergency mobile power supply will make it difficult to reasonably arrange the intake and exhaust components of the internal combustion generator, thereby affecting the normal operation of the internal combustion generator. Specifically, the intake pipe is too short, resulting in the air filter being too close to the internal combustion generator, or the exhaust pipe is too short, resulting in the muffler being too close to the internal combustion generator. The air filter or muffler is easily affected by the heat of the internal combustion generator, resulting in failure to work normally. Summary of the Invention

[0004] The present invention provides an emergency mobile power supply, aiming to solve the problem that the prior art cannot reduce the mutual influence of heat between devices in a small volume.

[0012] The first partition separates the shell into the second accommodating chamber and the first accommodating chamber;

[0013] The second partition is provided on the first partition, and the second partition divides the first partition into a plurality of installation spaces;

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

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

[0039] An embodiment of the present invention provides an emergency mobile power supply, which is used to solve the problem that the prior art cannot reduce the mutual influence of heat between devices in a small volume.

[0040] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] See also Figures 1 to 6 The present invention provides an emergency mobile power supply, comprising: a housing 1 having a second accommodating cavity 11 and a first accommodating cavity 10, a generator (not shown in the figure) disposed in the second accommodating 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 housing 1 forming the first accommodating chamber 10, and the exhaust pipe 21 is provided through the second accommodating chamber 11 and the first accommodating chamber 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 duct 31 . The air filter 30 is arranged in the first accommodating chamber 10 . The air filter 30 is connected to the generator through the air intake duct 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 accommodating chamber 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 chemical energy of the fuel is converted into mechanical energy through the internal combustion engine, and then the mechanical energy is converted into electrical energy; and the mixture after the combustion of the fuel and air is discharged from the generator through the exhaust pipe 21 and after being processed by the muffler 20, thus completing a round of air circulation.

[0045] From the above working process, it can be seen that the generator is located in the second accommodating chamber 11, the air filter 30 and the muffler 20 are both arranged in the first accommodating chamber 10 or outside the first accommodating chamber 10, and the generator, air filter 30 and muffler 20 are arranged in different cavities. The heat of the generator has limited impact on the air filter 30 and the muffler 20. Combined with the smallest possible generator volume (such as a short-axis generator, etc.), this emergency mobile power supply can reduce the heat transfer between devices while requiring a small volume.

[0046] Compared with the existing technology, it has the following advantages: First, it can reduce the mutual transfer of heat between devices in a small overall volume, that is, the generator and the air filter 30 and the muffler 20 are arranged in separate cavities, and the air filter 30 and the muffler 20 are arranged in the second cavity, and the size of the generator is compressed as much as possible, so as to achieve the purpose of small overall volume and low heat transfer, and avoid the prior art in order to compress the overall volume, and arrange the air filter 30 and the muffler 20 close to the generator, resulting in heat transfer between devices, thereby affecting normal operation; second, it has a wide range of applicability, that is, compared with the prior art using battery cells, since this embodiment uses an internal combustion generator, the internal combustion generator can work under various harsh environmental conditions, and its mechanical structure and working principle make it highly tolerant to the environment, fully meeting the needs of emergency use.

[0047] In the application scenarios of this embodiment, the emergency mobile power supply of this embodiment can provide temporary power support in the event of a power outage or insufficient power supply to ensure the operation of key equipment and systems. The applicable scenarios include but are not limited to application in factory production power outages, application in supermarket power outages, application in medical power outages, application in traffic accidents, and application in natural disaster rescue and relief.

[0048] In a specific embodiment, Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, an achievable structure of the shell 1 is further provided. The shell 1 includes an upper shell 1 having a first accommodating chamber 10 and a lower shell 1 having a second accommodating chamber 11. The upper shell 1 is used to carry the air filter 30 and the muffler 20, and the lower shell 1 is used to accommodate the generator, that is, the second accommodating chamber 11 is arranged below the first accommodating chamber 10, and the volume of the second accommodating chamber 11 is smaller than the volume of the first accommodating chamber 10, that is, the volume of the upper shell 1 is larger than the volume of the lower shell 1, and an inverted "convex" character is formed between the upper shell 1 and the lower shell 1. During specific implementation, a structure with a small bottom and a large top is formed, which can reduce the floor space and is conducive to application in emergency scenarios.

[0049] It should be noted that, in addition to being a combination of an upper shell 1 and a lower shell 1 , the shell 1 may also be two shells arranged in parallel and side by side, or in other adjacent arrangements.

[0050] In one embodiment, if Figure 1 and Figure 2 As shown, the achievable structure of the upper shell 1 is further provided, and the upper shell 1 includes an upper frame body, a top plate, a first partition plate 13, an oil tank 15, a plurality of first side plates and a control panel 16. The bottom surface of the upper frame body is fixedly provided with the first partition plate 13, the top surface of the upper frame body is fixedly provided with the top plate, the two opposite sides of the upper frame body are fixedly provided with the first side plates, the first side plates are hinged with side doors and a ventilation plate assembly 4 with ventilation holes 400, the remaining two sides of the upper frame body are fixedly provided with a control panel 16 and the oil tank 15, and the oil tank 15 is provided with a ventilation hole. The oil port 150 and the oil pump port 151, the oil pump tank is installed on the oil pump port 151, and a wave-breaking plate is provided in the oil tank 15; the top plate, the first partition plate 13, the two first side plates, the control panel 16 and the oil tank 15 are enclosed to form a first accommodating chamber 10. During specific implementation, the user can use the oil pump to pump the oil in the oil tank 15 into the generator; the user can also open the side door on the first side panel to store items in the first accommodating chamber 10 or take them out from the first accommodating chamber 10; the user can also adjust the output of the generator on the control panel 16.

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

[0052] In one embodiment, if Figures 3 to 6 As shown, in order to reduce the heat transfer of the exhaust pipe 21, an insulating pipe 12 is provided in the first accommodating chamber 10, one end of the insulating pipe 12 is connected to the second accommodating chamber 11, and the other end of the insulating pipe 12 forms an opening on the outer shell 1 for installing the muffler 20 soft channel, that is, the insulating pipe 12 is connected to the second accommodating chamber 11 and the outside of the outer shell 1; the exhaust pipe 21 is provided in the insulating pipe 12 to form a double-layer pipe. During specific implementation, the heat of the exhaust pipe 21 will be blocked by the insulating pipe 12, which can effectively prevent the heat of the exhaust pipe 21 from being transferred to the first accommodating chamber 10, thereby preventing the heat of the exhaust pipe 21 from affecting other components.

[0053] In this embodiment, if Figure 5 and Figure 6 As shown, there is a gap between the insulated pipe 12 and the exhaust pipe 21. During specific implementation, a gap is formed between the double-layer pipes, which is equivalent to an additional insulation space. Heat needs to pass through more thermal resistance links in the process of being transferred from the exhaust pipe 21 to the insulated pipe 12, that is, the heat must first pass through the gap and then reach the insulated pipe 12. Compared with the original insulated pipe 12, an insulation barrier is added, which greatly improves the insulation effect of the entire pipe system and prevents the heat of the exhaust pipe 21 from affecting other components.

[0054] In this embodiment, if Figure 5 and Figure 6 As shown, the axial direction of the insulated pipe 12 is the same as the direction of the line connecting the second accommodating chamber 11 and the first accommodating chamber 10. In specific implementation, the insulated pipe 12 is arranged in the direction of the line connecting the first accommodating chamber 10 and the second accommodating chamber 11. For example, when the first accommodating chamber 10 and the second accommodating chamber 11 are arranged horizontally, the insulated pipe 12 is arranged horizontally; for another example, when the first accommodating chamber 10 and the second accommodating chamber 11 are arranged up and down, the insulated pipe 12 is arranged vertically. The purpose is to make the insulated pipe 12 form the shortest straight line between the generator and the muffler 20, so that the space of the insulated pipe 12 in the outer shell 1 is more compact.

[0055] In this embodiment, if Figure 5 and Figure 6 As shown, in order to avoid mutual influence of heat between pipes, a first partition 13 and two second partitions 14 are provided in the outer shell 1; a first partition 13 is provided between the upper outer shell 1 and the lower outer shell 1 to separate the first accommodating cavity 10 and the second accommodating cavity 11, and the two second partitions 14 are provided on the first partition 13, and the two second partitions 14 separate the first partition 13 to form multiple installation spaces; the exhaust duct 21 and the intake duct 31 are located in different installation spaces. During specific implementation, the exhaust duct 21 and the intake duct 31 are arranged in two different spaces, and the heat or gas of the intake duct 31 and the exhaust duct 21 will not affect each other, thereby reducing the mutual influence between components.

[0056] Among them, the first accommodating cavity 10 is divided into a first installation space and a second installation space by the second partition 14, and the first partition 13 in the first installation space is provided with an insulating through-hole for the exhaust pipe 21 to pass through, and a circle of insulating surrounding walls is provided outside the insulating through-hole, and the insulating surrounding walls enclose the above-mentioned insulating pipe 12. The remaining space of the first installation space is the item installation space. The user can open the first installation space through the side door hinged on the first side panel, and a kettle seat 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 is provided with an air filter through-hole for the intake pipe 31 to pass through, and the intake pipe 31 passes through the second installation space and is connected to the air filter 30. The second installation space is also provided with an oil-water separator 17 and a coolant tank 18. The user can also open the second installation space through the side door hinged on the first side panel on the other side.

[0057] Based on the above embodiment, in a specific embodiment, as Figure 1 、 Figure 5 and Figure 6 As shown, a feasible structure of the ventilation plate assembly 4 is further provided, and the ventilation plate assembly 4 includes a ventilation plate 40, a baffle 41 and a wing plate 42; a plurality of ventilation holes 400 are provided on the ventilation plate 40, and a baffle 41 is provided between the plurality of ventilation holes 400 and the interior of the shell 1; the bottom of the baffle 41 is connected and fixed to the bottom of the ventilation plate 40, and the two sides of the ventilation plate 40 are connected and fixed to the baffle 41 through the wing plate 42, and 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 plate 40 cooperates to form a pocket-shaped structure on the inner side of the ventilation plate 40. During specific implementation, the ventilation hole 400 can ensure that the outside of the shell 1 is connected with 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 shell 1, and due to the setting of the baffle 41, after the external water droplets or debris enter the ventilation hole 400, they will be blocked in the pocket-shaped structure by the baffle 41, preventing the external water droplets or debris from directly entering the various cavities through the ventilation hole 400, affecting the normal operation of the emergency mobile power supply equipment.

[0058] In this embodiment, if 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 arranged obliquely 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 direction of airflow. 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, and then the first guide section 410 guides and then guides the airflow to move vertically upward to form a regular laminar flow, thereby avoiding irregular flow of airflow. In addition, the setting of the inclined surface of the second guide section 411 can accelerate the airflow and enhance the heat dissipation effect.

[0059] In a specific embodiment, Figures 1 to 6 As shown, a feasible structure of the muffler 20 is further provided. The muffler 20 is arranged at the top of the shell 1. After the muffler 20 is arranged at the top, on the one hand, it can avoid the influence of the heat of the generator on the muffler 20, and on the other hand, it can make the exhaust of each cylinder more evenly collected in the muffler 20, reduce the exhaust interference phenomenon, and make the exhaust process of the engine more stable and efficient.

[0060] In one embodiment, if Figures 1 to 6 As shown, a silencer protective cover 22 is provided outside the silencer 20, and a heat dissipation hole is provided on the silencer protective cover 22, which can not only protect the normal operation of the silencer 20, but also ensure the heat dissipation. Among them, the silencer 20 can be one of an absorption silencer 20, a reflection silencer 20, and an interference silencer 20. As long as the silencer 20 can achieve the silencer function, technical personnel in this field can consider choosing it, and I will not go into details here.

[0061] In one embodiment, if 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, the muffler 20 will not be affected by the heat of the generator, ensuring that it can operate normally.

[0062] In a specific embodiment, Figure 5 and Figure 6 As shown, a feasible structure of the exhaust duct 21 is further provided. The exhaust duct 21 includes a hard pipe, a pipe connector and a hose. The hard pipe is used to be connected and installed with the air outlet of the generator, and the hose is connected and installed with the air inlet of the muffler. The hard pipe and the hose are connected by the pipe connector.

[0063] It should be pointed out that the pipe connector can be a sleeve-type connector or a clamp-type connector. As long as the pipe connector can achieve the connection between soft and hard pipes, technical personnel in this field can consider choosing it, and no further details will be given here.

[0064] In a specific embodiment, the generator is an internal combustion generator, which is a short-shaft generator. The internal combustion generator can be a diesel generator, a gasoline generator, or a natural gas generator. Those skilled in the art can make a choice based on actual needs, and no further details will be given here.

[0065] In a specific embodiment, Figures 1 to 6 As shown, an automatic lifting leg 5 is further provided outside the shell 1. The automatic lifting leg 5 is arranged at the four corners of the shell 1. The automatic lifting leg 5 is connected and fixed to the upper shell 1. During specific implementation, the automatic lifting leg 5 can adapt to various terrains, so that the emergency mobile power supply can work smoothly. Among them, the specific structure of the automatic lifting leg 5 can be referred to the prior art (application number 202320671595.8), which will not be elaborated here.

[0066] In a specific embodiment, Figures 1 to 6 As shown, a roller 6 is further provided outside the shell 1, and the roller 6 is installed on the bottom of the shell 1 so as to be flipped up and down through a rotating shaft. When the emergency mobile power supply needs to be moved in a sliding manner, the roller 6 can be flipped down and fixed so that it slides on the roller 6. When sliding is not required, the roller 6 can be flipped upward and fixed so that the bottom of the shell 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 elaborated here.

[0067] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
