DETAILED DESCRIPTION

[0018] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Embodiment 1, as Figures 1 to 4 As shown, a portable large-capacity mobile power source for outdoor use includes a heat dissipation control unit and a monitoring processing unit. The heat dissipation control unit includes a heat dissipation component, a servo motor 2 and a controller. The monitoring processing unit includes a temperature sensor disposed in a mobile power source housing 3 for monitoring the operating temperature of components and a speed sensor for monitoring the speed of the servo motor. The monitoring and processing unit is used to obtain the operating temperature of the components and the speed of the servo motor 2 in real time and perform matching processing; The controller is used to control the servo motor 2 to increase or decrease the speed according to the matching processing result, and drive the heat dissipation component to switch the working state according to the working temperatures of different components obtained in real time to achieve heat dissipation of the mobile power supply housing 3. It is particularly suitable for use on handheld mobile power supplies, reduces power loss, ensures heat dissipation efficiency, and enables the mobile power supply to be used for a longer time. A handle is provided on the side of the mobile power supply housing 3 for easy carrying.

[0020] During operation, the servo motor 2 drives the fan to rotate, thereby dissipating heat for components. The heat dissipation method of the portable large-capacity outdoor mobile power supply of the present invention includes the following methods: In the first step, a speed sensor is installed on one side of the servo motor 2 to monitor the speed of the servo motor 2, and a temperature sensor 5 is installed on the surface of the component to monitor the working temperature of the component; The second step is to obtain the operating temperature t of the components monitored by the temperature sensor in real time g The speed sensor monitors the speed of the servo motor 2, and matches the preset temperature according to the obtained speed of the servo motor 2. g and the relationship between the preset temperature to control the servo motor 2 to speed up or slow down to achieve the heat dissipation of the mobile power supply housing 3; The preset temperature is the preset internal temperature range of the mobile power supply housing 3 when the servo motor 2 is working at different speeds [t i ,t j ], if t g <t i , the controller controls the servo motor 2 to reduce the speed; if t g >t j, the servo motor 2 is controlled to increase the speed; the purpose of monitoring the motor speed, the operating temperature of the components and judging whether the motor speed and the operating temperature of the components are compatible is achieved to control the motor to speed up, slow down or maintain the current speed.

[0021] In the prior art, a fixed-power driving device is usually set to drive the fan to dissipate heat for the mobile power supply. However, different mobile power supplies, especially different components in the mobile power supply, have different heat dissipation requirements. Therefore, when the existing corresponding mobile power supply has a higher heat dissipation requirement, the number of driving devices and fans is usually increased to achieve a better heat dissipation effect. Not only does it occupy a large space, but the energy loss when the driving device drives the fan to rotate is large. If multiple driving devices are set, the energy loss will be maximized, which is not suitable for use in portable mobile power supplies. Therefore, in the present invention, the driving device is set to a servo motor 2 with adjustable speed. By adjusting the speed of the servo motor 2, better heat dissipation of the mobile power supply can be achieved, reducing the energy loss problem. In addition, in the present invention, by monitoring the operating temperature of the components and the speed of the servo motor 2 and judging the temperature and speed adaptability through the judgment module, the speed of the servo motor 2 can be reasonably reduced, increased or maintained, so as to fully utilize the heat dissipation energy and save electric energy.

[0022] For example, in the prior art, the rotation speed of the servo motor 2 is 1000-7000 rpm; when the mobile power source is in operation, its internal normal temperature is usually between 45-65°C; assuming that the rotation speed of the servo motor 2 is 2000 rpm, the corresponding normal temperature range is between 45-65°C, and 45°C is the first threshold temperature t i , 65℃ is the second threshold temperature t j ; When the operating temperature t in the mobile power supply housing 3 is monitored g At 30°C, it means that there is no need to dissipate heat inside the mobile power housing 3, and the speed of the servo motor 2 can be reduced accordingly, so that the mobile power housing 3 can maintain continuous heat dissipation while reducing the energy consumption of the servo motor 2 due to the reduced heat dissipation demand, thereby saving electricity; When the operating temperature t in the mobile power supply housing 3 is monitored g At 50° C., it means that the temperature inside the mobile power supply housing 3 is the normal working temperature, and there is no need to adjust the speed of the servo motor 2 additionally. The speed of the servo motor 2 can be maintained unchanged by the controller. When the operating temperature t in the mobile power supply housing 3 is monitored g At 70°C, it means that the temperature inside the mobile power supply housing 3 is too high and needs urgent heat dissipation. At this time, the speed of the servo motor 2 is increased by the controller to improve the heat dissipation effect. When the heat drops to the corresponding threshold range, the speed of the servo motor 2 can be adjusted again by the controller.

[0023] like Figure 4 , Fig.10 - Fig.11 As shown, the heat dissipation control unit of the present invention is used in conjunction with the monitoring and processing unit, and the heat dissipation component includes a fan housing 1, which is installed on one side of a mobile power supply housing 3, and components are installed in the mobile power supply housing 3. Support plates 25 with holes are fixedly provided at both end openings of the fan housing 1, and the servo motor 2 is fixedly installed on the inner side surface of one of the support plates 25 with holes. The rotating shaft on the servo motor 2 is fixedly connected to a power shaft box 23, and the power shaft box 23 is arranged in the middle position inside the fan housing 1. Blades 28 are arranged on the outer ring of the power shaft box 23. When working, the servo motor 2 is started, and the servo motor 2 drives the blades 28 to rotate through the power shaft box 23, so that wind force is blown into the interior of the mobile power supply housing 3, thereby dissipating heat for the components.

[0024] The temperature sensor 5 is installed on the component to monitor the working temperature of the component to determine whether the working temperature is below the normal working temperature range, so as to adjust the speed of the servo motor 2 in time through the controller to adjust the heat dissipation effect.

[0025] Since there are multiple components, usually including an inverter 7 and a lithium battery 8, it is insufficient to use one temperature sensor 5 to monitor the temperature of the overall environment inside the mobile power supply housing 3 in the prior art. In the present invention, temperature sensors 5 are installed on the surfaces of corresponding components to monitor each different component in a targeted manner based on the different heat generation capacities of the components.

[0026] It should be noted that components usually also include controllers, switches and other mechanisms, which will not be elaborated here.

[0027] Even if a plurality of servo motors 2 and fans are provided on the existing mobile power housing 3, the wind is only transmitted to the internal environment of the mobile power housing 3, and then the wind is discharged through the heat dissipation net 4 on the side of the mobile power housing 3, which is a centralized heat dissipation. Because the internal space of the mobile power housing 3 is relatively large, if the wind is directly transmitted to the inside of the mobile power housing 3, there will be a certain loss, thereby reducing the efficiency of the wind to take away the heat from the surfaces of different components; and when the overall ambient temperature inside the mobile power housing 3 is high, there will be a delay in heat dissipation when the heat dissipation effect is improved, which will lead to the problem of reduced service life of the corresponding components.

[0028] For example, the lithium battery 8 is a component that is easy to generate heat, and as long as it is used continuously when the mobile power supply is running, the inverter 7 or the controller is also easy to generate heat, but it is not used frequently, and only generates a high temperature under continuous inverter current or other circumstances; therefore, when different components generate different heat, there will be a problem of delayed temperature rise in the mobile power supply housing 3. When the temperature on the lithium battery 8 is 60°C, the ambient air temperature inside the mobile power supply housing 3 is 40°C. In the prior art, the temperature sensor 5 monitors the ambient air temperature inside the mobile power supply housing 3. Therefore, when the temperature sensor 5 monitors the air temperature inside the mobile power supply housing 3 at 70°C, the temperature on the lithium battery 8 may exceed 80°C. At this time, if the heat dissipation effect is further improved, the heat dissipation delay phenomenon will be formed. After the lithium battery 8 has been affected by high temperature for a certain period of time, its performance and service life will be reduced.

[0029] In the present invention, a plurality of temperature sensors 5 are provided, and the plurality of temperature sensors 5 are installed on the surfaces of different components, so that the temperatures of the surfaces of different components can be accurately and timely monitored, so as to cooperate with the servo motor 2 and other mechanisms in the present invention to dissipate heat in time, and the problem of heat dissipation delay will not occur.

[0030] like Figure 5 - Figure 6 As shown, in the present invention, a bellows 12 is installed at the opening of the fan housing 1 corresponding to the inside of the mobile power housing 3, and a heat dissipation main pipe 13 is connected to the bellows 12. The heat dissipation main pipe 13 is bent and distributed and passes over multiple components in sequence. A heat dissipation branch pipe 14 is connected to the position corresponding to each component on the heat dissipation main pipe 13, and an electromagnetic switch mechanism 15 for controlling the heat dissipation branch pipe 14 to be fully opened, half opened or closed is provided at the position corresponding to the heat dissipation branch pipe 14 in the heat dissipation main pipe 13; when working, the wind force generated when the servo motor 2 drives the power shaft box 23 and the blades 28 to rotate is concentratedly input into the bellows 12 and then enters the heat dissipation main pipe 13. If the temperature of the component at the corresponding position is high, the electromagnetic switch mechanism 15 corresponding to this place can be controlled by the controller to open, so that the wind force directly passes through the heat dissipation branch pipe 14 and blows on the surface of the component at the corresponding position, which has strong pertinence and high heat dissipation efficiency, replacing the original method of directly conveying the wind force to the internal space of the mobile power housing 3, and then acting on the surface of the component after loss in the internal space of the mobile power housing 3.

[0031] like Figure 7 - Fig.10 As shown, further, the heat dissipation branch pipe 14 also has a fully open, half-open or closed state, which is set for the following operating conditions: For example, when it is detected that only the lithium battery 8 generates high heat, the controller controls the heat dissipation branch pipe 14 corresponding to the position above the lithium battery 8 to be half-open, and the other heat dissipation branch pipes 14 are closed. During heat dissipation, only the components that need heat dissipation are dissipated, which fully saves heat dissipation energy, improves the heat dissipation effect, and reduces energy loss during the heat dissipation process.

[0032] When it is monitored that the temperature of the lithium battery 8 and the inverter 7 is too high and the temperature of other components is normal or low, the controller controls the corresponding heat dissipation branch pipe 14 above the lithium battery 8 to be fully opened, the heat dissipation branch pipe 14 above the corresponding inverter 7 to be half opened, and the other heat dissipation branch pipes 14 are closed. The wind force during heat dissipation will only be transmitted to the lithium battery 8 and the inverter 7, thereby achieving the purpose of controlling the corresponding heat dissipation main pipe 13 to dissipate air at any different position and multiple positions at the same time for heat dissipation; it is particularly suitable for use in special scenarios where different components are distributed at different positions in the mobile power supply housing 3 and the heat generation situation changes at any time.

[0033] It should be noted that the figure only shows the schematic diagram of the lithium battery 8 and the inverter 7 and the schematic diagram of the heat dissipation main duct 13 distributed above the lithium battery 8 and the inverter 7; the heat dissipation main duct 13 of different shapes can be temporarily set according to the number and distribution positions of the components inside the mobile power supply housing 3. The principle is the same and will not be repeated here.

[0034] When it is monitored that all components inside the mobile power supply housing 3 are within the normal operating temperature range, the controller controls all the heat dissipation branches 14 to be fully opened, and the servo motor 2 provides continuous low-speed heat dissipation.

[0035] In the prior art, when controlling the wind to be discharged from the auxiliary pipe on the main pipe, it is usually controlled by a solenoid valve. However, the solenoid valve control has a defect, that is, when the number of opening requirements of different auxiliary pipes is different, a part of the wind will still flow through the entire length of the main pipe before being discharged from the corresponding auxiliary pipe, and there is wind loss in this process; therefore, the present invention is based on a method of half-opening the heat dissipation branch pipe 14, that is, the wind in the heat dissipation main pipe 13 can be discharged through the half-open heat dissipation branch pipe 14 and will not continue to be transported along the heat dissipation main pipe 13, thereby solving the problem of this part of wind loss.

[0036] Specifically, the electromagnetic switch mechanism 15 includes a baffle 16 and a sealing strip 22. The baffle 16 is a plate-shaped structure. The sealing strip 22 is fixedly arranged at both ends of the baffle 16 and movably fits on the inner wall of the heat dissipation main pipe 13. The inner walls on both sides of the heat dissipation main pipe 13 are provided with a first arc-shaped groove 17 and a second arc-shaped groove 18. Both ends of the first arc-shaped groove 17 and the second arc-shaped groove 18 are respectively fixedly embedded with a first electromagnet 19 and a second electromagnet 20. Magnets 21 are fixedly arranged on both sides of the baffle 16 near the sealing strip 22. The magnets 21 are slidably arranged in the corresponding first arc-shaped groove 17 or the second arc-shaped groove 18. The magnets 21 are located between the corresponding first electromagnets 19 and the second electromagnets 20. The first electromagnets 19 and the second electromagnets 20 are connected to the controller.

[0037] During operation, when the second electromagnet 20 below the first arc-shaped chute 17 is activated, the second electromagnet 20 here attracts the magnet 21 at one end of the baffle 16 and slides down along the first arc-shaped chute 17, and the first electromagnet 19 above the second arc-shaped chute 18 is activated, and the first electromagnet 19 here attracts the second electromagnet 20 at the other end of the baffle 16 and slides up along the second arc-shaped chute 18, so that the baffle 16 forms a tilted state. At this time, the heat dissipation distribution pipe 14 is in a state as shown in FIG. Figure 7 and Figure 8 Shown in half-open state.

[0038] It should be noted that when the control magnet 21 moves in the corresponding first arc-shaped slot 17 and the second arc-shaped slot 18, the magnetic poles of the corresponding first electromagnet 19 and the second electromagnet 20 can also be controlled to change so as to achieve the purpose of repulsion or attraction between the magnet 21. The auxiliary magnet 21 can slide from one end to the other end in the first arc-shaped slot 17 or the second arc-shaped slot 18 of a certain length.

[0039] When the second electromagnet 20 under the first arc-shaped chute 17 and the second arc-shaped chute 18 is activated and attracted to the magnet 21, the baffle 16 completely blocks the heat dissipation branch pipe 14. At this time, the heat dissipation branch pipe 14 is in a state as shown in FIG. Fig. 9 The closed state is shown.

[0040] When the first electromagnet 19 above the first arc-shaped chute 17 and the second arc-shaped chute 18 is activated and attracted between the magnet 21, the baffle 16 is attached to the inner wall above the heat dissipation main pipe 13. At this time, the heat dissipation branch pipe 14 is in a state as shown in FIG. Fig.10 Shown in the fully open state.

[0041] The sealing strips 22 at both ends of the baffle 16 are used to achieve sealing between the ends of the baffle 16 and the inner wall of the heat dissipation main pipe 13, which will not be described in detail here.

[0042] In actual use, multiple heat dissipation distribution pipes 14 can be set on each component to achieve the purpose of heat dissipation at multiple points and improve heat dissipation uniformity. This is a common choice for technicians in this field and will not be elaborated here.

[0043] Furthermore, when the heat dissipation branch duct 14 is in a half-open state, the wind in the heat dissipation main duct 13 is cut off here and can only be guided by the inclined baffle 16 and then transported to the heat dissipation branch duct 14. The wind is discharged after being inclinedly guided, which reduces the problem of wind backflow. Therefore, in the present invention, the heat dissipation branch duct 14 can be switched between the three states of fully open, half open, and closed to achieve better heat dissipation effects while reducing wind backflow losses.

[0044] like Fig.12 As shown in the figure, the power shaft box 23 in the present invention is a hollow structure, and a rotating rod 29 is fixedly provided at the middle position of the outer ring of the power shaft box 23 on the blade 28. The rotating rod 29 movably extends into the interior of the power shaft box 23, and a plurality of first racks 31 are fixedly provided at the outer ring of one end of the rotating rod 29 extending into the interior of the power shaft box 23. A driving motor 24 is fixedly installed on the inner side surface of another perforated support plate 25, and the rotating shaft on the driving motor 24 movably extends into the interior of the power shaft box 23 and is fixedly connected between the rotating plate 30. The rotating plate 30 is arranged in the interior of the power shaft box 23, and a plurality of second racks 32 are fixedly provided on a side of the rotating plate 30 close to the rotating rod 29, and the second racks 32 and the first racks 31 are meshed with each other; when the driving motor 24 is started, it can drive the rotating plate 30 to rotate, and the blade 28 is provided with a plurality of The plurality of blades 28 are distributed at equal angles along the outer ring of the power shaft box 23, and the plurality of second racks 32 are distributed in a circular array along the axis of the rotating plate 30. The distribution trajectories of the plurality of second racks 32 are circular and correspond to the plurality of first racks 31 at the outer ring of the rotating rods 29. When the rotating plate 30 rotates, the second racks 32 and the first racks 31 drive the rotating rods 29 and the blades 28 to rotate. When the blades 28 rotate 180°, the driving motor 24 stops. Due to the meshing action of the first rack 31 and the second rack 32, the blades 28 are positioned. When the servo motor 2 is started again at this time, due to the change in the inclination direction of the blades 28, the wind will flow in the reverse direction, thereby achieving the purpose of suction-type heat dissipation inside the mobile power supply housing 3 and sucking away the dust inside the mobile power supply housing 3 during heat dissipation. The structure is simple, but the effect is good, and it is easy to promote.

[0045] It should be noted that the blades 28 are made of plastic material that can be plastically deformed, so that they can be easily rotated and adjusted along the surface of the power shaft box 23, and when the power shaft box 23 rotates, the blades 28 can be driven to fully unfold to transmit wind power.

[0046] The controller in the present invention is used to control the servo motor 2 to increase or decrease the speed according to the matching processing result, and drive the heat dissipation component to switch the working state according to the working temperature of different components obtained in real time to achieve the heat dissipation of the mobile power supply, including: If the component operating temperature obtained in real time is greater than or equal to the highest value of the preset temperature corresponding to the speed of the servo motor 2 obtained in real time, the controller controls the servo motor 2 to increase the speed. If the component operating temperature obtained in real time is less than the lowest value of the preset temperature corresponding to the speed of the servo motor 2 obtained in real time, the speed is reduced. At the same time, the heat dissipation distribution pipes 14 arranged at different component positions in the heat dissipation assembly are controlled to switch between the three states of fully open, half open, and closed to perform heat dissipation processing.

[0047] Considering that the same servo motor 2 can be used to switch the direction of wind power delivery in the present invention, it is necessary to absorb dust when absorbing the heat inside the mobile power supply housing 3. Therefore, a hole 26 is provided on a perforated support plate 25 on which the servo motor 2 is installed. The outer side of the hole 26 is rotatably connected to a filter plate assembly 27. The filter plate assembly 27 includes a frame 6, a filter cotton layer 9 and a rotating shaft 11. The frame 6 is a rectangular frame structure. The filter cotton layer 9 is fixedly installed inside the frame 6 and blocks the opening of the hole 26. The rotating shaft 11 is fixedly arranged at one end of the frame 6. A rotating shaft 11 is fixedly welded on the perforated support plate 25. The seat 10 is rotatably connected with the end of the rotating shaft 11, and a torsion spring is provided at the rotating connection for the rotating shaft 11 to reset after rotation; when the dust in the mobile power supply housing 3 is sucked away, the wind pushes the filter cotton layer 9 to make the frame 6 rotate around the rotating shaft 11, and the hole 26 is opened to discharge heat and dust. When the wind is transported to the inside of the mobile power supply housing 3, the side of the filter cotton layer 9 away from the hole 26 is subjected to the wind. The pushing effect of the wind and the reset effect of the torsion spring both reset the filter cotton layer 9 to fit on the hole 26, allowing the wind to pass through, but preventing dust from entering the mobile power supply housing 3.

[0048] In Example 2, Fig.11 As shown, when the heat dissipation branch duct 14 is in a half-open state, the wind in the heat dissipation main duct 13 is cut off here and can only be guided by the inclined baffle 16 and then transported to the heat dissipation branch duct 14, and the baffle 16 is made of elastic material; the baffle 16 is blown by the wind to form an arc surface structure, which is beneficial to avoid further backflow of wind and improves the effect of reducing wind loss.

[0049] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
