Description

Technical Field

[0001] This application relates to the field of mobile power bank insulation technology, and in particular to an outdoor power supply with a thermal management system. Background Technology

[0002] Outdoor power supplies are portable mobile power sources. Unlike mobile phone power banks, outdoor power supplies store a large amount of electrical energy. In addition to charging small devices such as mobile phones, they can also be used for various commonly used medium and large electrical devices such as computers, photography lights, and rice cookers. Outdoor power supplies can also be used in the construction industry to charge the batteries of small and medium-sized equipment such as electric drills.

[0003] In existing technologies, outdoor power supplies typically house lithium-ion batteries and are equipped with multiple charging interfaces such as USB, DC, and AC at their output terminals to ensure compatibility with various devices. The power supply itself is generally charged via wired charging or solar panels. However, since outdoor power supplies are usually used outdoors, their temperature rises in hot weather due to the heat and their own heat generation, leading to a decrease in efficiency at high temperatures. Conversely, charging efficiency decreases in lower outdoor temperatures. Therefore, outdoor power supplies are easily affected by temperature when used outdoors, and minimizing the impact of outdoor temperature on their performance is a key technical challenge in this field. Summary of the Invention

[0004] To reduce the impact of outdoor temperature on the use of outdoor power supplies, this application provides an outdoor power supply with a thermal management system.

[0005] The outdoor power supply with a thermal management system provided in this application adopts the following technical solution:

[0006] An outdoor power supply with a thermal management system includes a housing. A mounting block is connected to the bottom wall of the housing. Insertion slots are formed on both side walls of the mounting block, and the two insertion slots are staggered in the height direction of the housing. A heating plate is inserted into each insertion slot and is electrically connected to a battery inside the housing. Sliding grooves are formed on the inner walls of both sides of the insertion slots, and a slider is slidably connected within each groove, extending slidably from the groove. Limiting grooves are formed on the side walls of the sliders. Limiting posts are connected to both sides of the heating plate, and the two limiting posts are... The device should be inserted into the corresponding limiting groove and can move and rotate within the limiting groove; several through holes are provided on both sides of the housing, and positioning components for positioning the heating plate are provided on both sides of the housing; limiting components for limiting the slider are provided in the sliding groove; a mounting bracket is connected to the top wall of the housing, and a fan is rotatably connected to the mounting bracket; an electric heating wire is connected to the mounting bracket, and the electric heating wire is located between the fan and the housing; a power supply for powering the fan and the electric heating wire is also connected to the mounting bracket; ventilation openings are provided on both the top and bottom walls of the housing.

[0007] By adopting the above technical solution, when the outdoor power supply is used in a cold environment, the operator pulls the heating plate, causing it to move out of the insertion slot. Simultaneously, the heating plate moves, causing the limiting post to move as well. After the limiting post contacts the inner wall of one end of the limiting slot, it drives the slider to move outward along the length of the slot. After the heating plate moves out of the insertion slot, the limiting component limits the heating plate, and then the heating plate rotates towards the outer wall of the housing. As the heating plate comes into contact with the housing, the positioning component positions the heating plate on the outer wall of the housing. Finally, a pre-set switch on the side wall of the heating plate is activated, heating the heating wire inside the heating plate, thus heating the housing and raising the outdoor power supply temperature to a suitable charging temperature. After use, the positioning component is removed, the heating plate rotates to be flush with the insertion slot, and then the heating plate is pushed into the insertion slot. Simultaneously, the limiting component limits the heating plate again, thus achieving the storage of the heating plate. When the outdoor temperature is low, the heating element can be turned on to preheat, and then the fan can be turned on to blow air onto the heating element. The hot air from the heating element will further enter the housing through the vent on the top wall of the housing, thus preheating the outdoor power supply in advance and achieving the best charging effect for the battery. When the outdoor temperature is high, the heating element can be turned off and only the fan can be turned on to blow air onto the housing. The hot air inside the housing will be blown out through the vent on the bottom wall of the housing, thus cooling the outdoor power supply.

[0008] When the outdoor power supply temperature rises, the high-temperature gas inside the casing flows out through the vents, while new, cooler air enters the casing. This cooler air exchanges heat with the battery before flowing out again, thus dissipating heat from the inside of the casing and lowering the internal temperature of the outdoor power supply, thereby extending its lifespan. This thermal management system can also raise the temperature of the outdoor power supply by removing the heating plate when it is in a cold environment, or lower it by allowing high-temperature gas to flow out through the vents when the internal temperature rises. This achieves temperature regulation of the outdoor power supply, reducing the impact of outdoor temperature on its operation.

[0009] Preferably, the limiting assembly includes a roller and a pull rope. The roller is rotatably disposed in the groove, and the pull rope is connected to the side wall of the roller and wound around the roller. The end of the pull rope away from the roller is connected to the side wall of the slider, and one end of the roller extends out from the outer side wall of the mounting block through the mounting block.

[0010] By adopting the above technical solution, during the movement of the slider, the pull rope is pulled, causing the roller to rotate and release the pull rope. After the pull rope is released until it is taut, the slider stops moving, and the part of the slider away from the pull rope extends out of the groove. At this time, the heating plate and the limiting post are located outside the insertion slot, and the operator can rotate the heating plate upward. When the heating plate is inserted into the insertion slot, the roller is rotated to retract the pull rope until the heating plate is fully inserted into the insertion slot, thus realizing the storage of the heating plate.

[0011] Preferably, the two rollers within the same insertion slot are coaxially connected by the same connecting rod.

[0012] By adopting the above technical solution, only one roller needs to extend from the side wall of the mounting block. Driving the roller extending from the mounting block to rotate, and then through the transmission action of the connecting rod, the synchronous rotation of the two rollers can be achieved, improving the synchronization rate of the two rollers in winding the rope, and at the same time improving the convenience of operation.

[0013] Preferably, the bottom wall of the chute is provided with an installation groove, the roller is rotatably connected in the installation groove, and the connecting rod passes through the installation groove.

[0014] Normally, the roller is directly connected to the slide groove, occupying the insertion position of the heating plate and resulting in a smaller heating plate size. By adopting the above technical solution, the roller is connected to the mounting groove, which does not occupy the position of the heating plate in the slide groove, thereby allowing for a larger heating plate and increasing the heating area of ​​the shell.

[0015] Preferably, the positioning component includes a positioning post and several elastic plates. The elastic plates are fixedly connected to the ends of the positioning post. The elastic plates are inclined relative to the side wall of the positioning post. The positioning post is connected to the side wall of the housing. A mating hole is provided through the side wall of the heating plate. The positioning post and the elastic plates pass through the mating hole. The ends of the elastic plates are in contact with the side wall of the heating plate.

[0016] By adopting the above technical solution, when positioning the heating plate on the outer wall of the housing, the rotation of the heating plate drives the positioning post and the elastic plate to move through the mating hole. Under the guidance of the inclined surface of the elastic plate, the inner wall of the mating hole pushes the elastic plate to stick to the side wall of the positioning post. After the elastic plate moves past the mating hole, the elastic plate elastically recovers its original shape, and the end of the elastic plate sticks to the side wall of the heating plate, which can limit the heating plate and make the heating plate stably stick to the outer wall of the housing.

[0017] Preferably, the inner wall of the housing is connected to a plurality of heat dissipation cylinders, the plurality of heat dissipation cylinders and the plurality of through holes are coaxially arranged and the positions correspond one-to-one, the inner wall of the heat dissipation cylinders is rotatably connected to a heat dissipation fan, and the plurality of heat dissipation fans are electrically connected to the battery inside the housing.

[0018] By adopting the above technical solution, when the outdoor power supply temperature rises, the cooling fan can be activated to create airflow within the casing, which then flows out through the heat dissipation cylinder and through the vents. This increases the airflow speed within the casing, improving the exchange rate of high-temperature gas and thus increasing the cooling rate of the outdoor power supply. When heating the casing, the operator can reverse the cooling fan, creating an airflow into the casing. The gas flows into the casing through the gap between the heating plate and the casing, achieving the effect of blowing hot air into the casing and further increasing the rate at which the outdoor power supply heats up.

[0019] Preferably, a baffle plate is rotatably connected to the inner wall of the heat sink near the through hole. The baffle plate is connected in the middle along the diameter direction of the inner wall of the heat sink. A lightweight torsion spring is provided at the rotatable connection of the baffle plate to cover the inside of the heat sink.

[0020] By adopting the above technical solution, the torsional force of the lightweight torsion spring is small. When the cooling fan generates airflow, it can blow the baffle plate to rotate and offset its coaxial position from the heat sink, allowing the airflow to pass through. At the same time, the rotation of the baffle plate torsional the lightweight torsion spring. After the cooling fan is turned off, the elastic force of the lightweight torsion spring will drive the baffle plate to rotate and return to the coaxial position with the heat sink, thereby sealing the heat sink and reducing the possibility of impurities from the outside of the casing entering the casing.

[0021] Preferably, the heating plate has a plurality of push rods connected to its side wall, which can be inserted into corresponding through holes. The push rods are not coaxial with the corresponding through holes, and the rotation axis of the push rods is offset from that of the baffle plate at the corresponding through hole.

[0022] By adopting the above technical solution, when the heating plate is in contact with the outer wall of the housing, the push rod moves through the through hole and then further inserts into the heat dissipation cylinder and pushes the baffle plate to rotate, so that the baffle plate removes the seal on the heat dissipation cylinder, thereby allowing the heated air near the heating plate to quickly enter the housing and improve the heating rate of the heating plate to the outdoor power supply.

[0023] Preferably, the heating plate has several threaded holes through its sidewall, and threaded blocks are threadedly connected to the threaded holes. Several push rods are respectively connected to the corresponding threaded blocks, and the push rods and the corresponding threaded blocks are coaxially arranged.

[0024] Setting the push rod directly on the side wall of the heating plate would result in an uneven surface of the heating plate, and the insertion slot would need to be larger to allow the push rod to enter the insertion slot. By adopting the above technical solution, after the heating plate is attached to the outer wall of the shell, the operator rotates the threaded block, causing the threaded block to move and drive the push rod to move through the through hole and insert into the heat dissipation cylinder to push the baffle plate to rotate. Before the heating plate enters the insertion slot, the threaded block is rotated again to move and drive the push rod back into the threaded hole, so that the heating plate can enter the insertion slot without being affected by the push rod.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. This thermal management system can heat the casing by removing the heating plate when the outdoor power supply is in a cold environment, thereby raising the temperature of the outdoor power supply; it can also activate the cooling fan to create outward airflow inside the casing when the internal temperature of the outdoor power supply rises, thereby cooling the outdoor power supply; thus, it achieves temperature regulation of the outdoor power supply and reduces the impact of outdoor temperature on the use of the outdoor power supply.

[0027] 2. The installation slot allows for a larger heating plate, increasing the heating area of ​​the housing.

[0028] 3. The design of the heat sink and cooling fan can improve the exchange rate of high-temperature gas inside the casing and increase the cooling rate of the outdoor power supply. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0036] This application discloses an outdoor power supply with a thermal management system. (Refer to...) Figure 1 The outdoor power supply with a thermal management system includes a housing 1, in which a lithium-ion battery is fixedly connected. Various charging connectors can be installed on the side wall of one side of the housing 1.

[0037] Reference Figure 1 A mounting bracket 5 is fixedly connected to the top wall of the housing 1. A fan 51 is rotatably connected to the mounting bracket 5, and a heating wire 52 is fixedly connected to the mounting bracket 5. The heating wire 52 is located between the fan 51 and the housing 1. A power pack 53 is also connected to the mounting bracket 5. Ventilation openings 18 are provided on both the top and bottom walls of the housing 1. When the outdoor temperature is low, the heating wire 52 can be turned on to preheat, and then the fan 51 can be turned on to blow air onto the heating wire 52. The hot air from the heating wire 52 will further enter the housing 1 through the ventilation openings 18 on the top wall of the housing 1, thereby preheating the outdoor power supply and achieving the best charging effect for the battery. When the outdoor temperature is high, the heating wire 52 can be turned off and only the fan 51 can be turned on to blow air into the housing 1. The hot air inside the housing 1 will be blown out through the ventilation openings 18 on the bottom wall of the housing 1, thereby cooling the outdoor power supply.

[0038] Reference Figure 1 and Figure 2A mounting block 11 is fixedly connected to the bottom wall of the housing 1. The mounting block 11 has insertion slots 12 on both sides of its side walls. The two insertion slots 12 are staggered in the height direction of the housing 1. The inner walls of both sides of the insertion slots 12 have sliding grooves 13. The bottom wall of the sliding grooves 13 has a mounting groove 14. A slider 17 is slidably arranged in the sliding grooves 13. The side wall of the slider 17 has a limiting groove 171. A heating plate 2 is inserted into the insertion slot 12. The heating plate 2 is a plate with heating wires inserted inside. The heating plate 2 has limiting posts 21 connected to both sides. The two limiting posts 21 are respectively inserted into the corresponding limiting grooves 171 and can move and rotate within the limiting grooves 171.

[0039] Reference Figure 1 and Figure 2 The slide groove 13 is provided with a limiting component 3 for limiting the slider 17. The limiting component 3 includes a roller 31 and a pull rope 32. The roller 31 is rotatably connected in the mounting groove 14. The pull rope 32 is fixedly connected to the side wall of the roller 31 and wound around the roller 31. The end of the pull rope 32 away from the roller 31 is fixedly connected to the side wall of the corresponding slider 17. One end of one of the rollers 31 passes through the mounting block 11 and extends out from the outer side wall of the mounting block 11. The same connecting rod 19 is fixedly connected between the two rollers 31 in the same insertion groove 12. The connecting rod 19 is coaxially connected to the roller 31 and passes through the mounting groove 14 at the same time.

[0040] Reference Figure 1 and Figure 3 Positioning components 4 are provided on both side walls of the housing 1. Each positioning component 4 includes a positioning post 41 and several elastic plates 42. The positioning post 41 is fixedly connected to the side wall of the housing 1, and the elastic plates 42 are fixedly connected to the ends of the positioning post 41. The elastic plates 42 are arranged circumferentially along the positioning post 41 and are inclined relative to the side wall of the positioning post 41. The end of the elastic plate 42 near the housing 1 is inclined away from the positioning post 41. A mating hole 24 is provided through the side wall of the heating plate 2. The positioning post 41 and the elastic plates 42 pass through the mating hole 24, and the ends of the elastic plates 42 are in contact with the side wall of the heating plate 2.

[0041] When the outdoor power supply is used in a cold environment, the operator pulls the heating plate 2, causing it to move out of the insertion slot 12. As the heating plate 2 moves, it also moves the limiting post 21. After the limiting post 21 moves within the limiting groove 171 and contacts the inner wall of one end of the limiting groove 171, it immediately drives the slider 17 to move out of the insertion slot 12 along the length of the slide groove 13. During the movement of the slider 17, the pull rope 32 is pulled, causing the winding roller 31 to rotate and release the pull rope 32. After the winding roller 31 releases the pull rope 32 until the pull rope 32 is straight, the slider 17 stops moving. The part of the slider 17 away from the pull rope 32 extends out of the slide groove 13. At this time, the heating plate 2 and the limiting post 21 are located outside the insertion slot 12. The operator can rotate the heating plate 2 upward, causing the heating plate 2 to drive the limiting post 21 to rotate within the limiting groove 171, causing the heating plate 2 to rotate towards the outer wall of the housing 1. At the same time, the heating plate 2 drives the mating hole 24 to move towards the positioning post 41.

[0042] As the heating plate 2 rotates, the positioning post 41 and the elastic plate 42 move through the mating hole 24. Guided by the inclined surface of the elastic plate 42, the inner wall of the mating hole 24 pushes the elastic plate 42 to adhere to the side wall of the positioning post 41. After the elastic plate 42 moves past the mating hole 24, the elastic plate 42 elastically recovers its shape, and the end of the elastic plate 42 adheres to the side wall of the heating plate 2, thus limiting the heating plate 2 and making it stably adhere to the outer wall of the housing 1. Finally, the switch preset on the side wall of the heating plate 2 is activated, which heats the heating wire inside the heating plate 2, thereby heating the housing 1 and raising the temperature of the outdoor power supply to a suitable charging temperature.

[0043] After the heating plate 2 is used, the operator pinches the elastic piece 42 and rotates the heating plate 2 to make the elastic piece 42 pass through the mating hole 24 again. The rotation of the heating plate 2 causes the elastic piece 42 and the positioning post 41 to come out of the mating hole 24. The heating plate 2 is rotated until it is flush with the insertion slot 12. Then the heating plate 2 is pushed into the insertion slot 12. At the same time, the roller 31 extending from the mounting block 11 is rotated. Under the transmission action of the connecting rod 19, the two rollers 31 synchronously retract the rope 32 until the heating plate 2 is completely inserted into the insertion slot 12, thus realizing the storage of the heating plate 2.

[0044] Reference Figure 4 and Figure 5The outer casing 1 has several through holes 15 on its two side walls, and several heat dissipation cylinders 16 are connected to the inner side wall of the casing 1. The heat dissipation cylinders 16 and the through holes 15 are coaxially arranged and their positions correspond one-to-one. A cooling fan 161 is rotatably connected to the inner wall of the heat dissipation cylinder 16, and the cooling fan 161 is electrically connected to the battery inside the casing 1. When the temperature of the outdoor power supply rises, the cooling fan 161 can be started to rotate, forming an airflow inside the casing 1, which flows out through the heat dissipation cylinders 16 and the through holes 15, thereby dissipating heat from the inside of the casing 1, lowering the temperature inside the outdoor power supply, and improving its service life. When heating the casing 1, the operator can start the cooling fan 161 to reverse, thereby forming an airflow into the casing 1. The gas flows into the casing through the gap between the heating plate 2 and the casing 1, achieving the effect of blowing hot air into the casing 1, further improving the heating rate of the outdoor power supply.

[0045] Reference Figure 5 A baffle plate 162 is rotatably connected to the inner wall of the heat sink 16 near the through hole 15. The middle part of the baffle plate 162 is connected along the diameter direction of the inner wall of the heat sink 16. A light torsion spring is provided at the rotatable connection of the baffle plate 162. The light torsion spring is used to twist the baffle plate 162 to a position coaxial with the heat sink 16 so as to cover the inside of the heat sink 16.

[0046] The lightweight torsion spring has a small torsional force. When the cooling fan 161 generates airflow, it can cause the baffle plate 162 to rotate and be offset from the coaxial position of the heat sink 16, allowing the airflow to pass through. At the same time as the baffle plate 162 rotates, it torsionals the lightweight torsion spring. After the cooling fan 161 is turned off, the elastic force of the lightweight torsion spring will drive the baffle plate 162 to rotate back to the coaxial position with the heat sink 16, thereby sealing the heat sink 16 and reducing the possibility of impurities from outside the housing 1 entering the housing 1.

[0047] Reference Figure 5 The heating plate 2 has several threaded holes 22 through the side wall. Threaded blocks 23 are threadedly connected to the threaded holes 22. A push rod 231 is fixedly connected to the side wall of the threaded block 23. The push rod 231 is coaxially arranged with the corresponding threaded block 23. The axis of the push rod 231 is offset from that of the through hole 15.

[0048] After the heating plate 2 is attached to the outer wall of the housing 1, the operator rotates the threaded block 23, which drives the push rod 231 to move closer to the through hole 15. After the push rod 231 moves through the through hole 15, it will further insert into the heat dissipation cylinder 16 and push the baffle plate 162 to rotate, so that the baffle plate 162 removes the seal on the heat dissipation cylinder 16. Thus, the heated air near the heating plate 2 can quickly enter the housing 1, increasing the heating rate of the heating plate 2 to heat the outdoor power supply.

[0049] The implementation principle of an outdoor power supply with a thermal management system according to an embodiment of this application is as follows:

[0050] When the outdoor power supply is used in a cold environment, the operator pulls the heating plate 2, causing it to move out of the insertion slot 12. As the heating plate 2 moves, it also moves the limiting post 21. After the limiting post 21 moves within the limiting groove 171 and contacts the inner wall of one end of the limiting groove 171, it immediately drives the slider 17 to move out of the insertion slot 12 along the length of the slide groove 13. During the movement of the slider 17, the pull rope 32 is pulled, causing the winding roller 31 to rotate and release the pull rope 32. After the winding roller 31 releases the pull rope 32 until the pull rope 32 is straight, the slider 17 stops moving. The part of the slider 17 away from the pull rope 32 extends out of the slide groove 13. At this time, the heating plate 2 and the limiting post 21 are located outside the insertion slot 12. The operator can rotate the heating plate 2 upward, causing the heating plate 2 to drive the limiting post 21 to rotate within the limiting groove 171, causing the heating plate 2 to rotate towards the outer wall of the housing 1. At the same time, the heating plate 2 drives the mating hole 24 to move towards the positioning post 41.

[0051] As the heating plate 2 rotates, the positioning post 41 and the elastic plate 42 move through the mating hole 24. Guided by the inclined surface of the elastic plate 42, the inner wall of the mating hole 24 pushes the elastic plate 42 to adhere to the side wall of the positioning post 41. After the elastic plate 42 moves past the mating hole 24, the elastic plate 42 elastically recovers its shape, and the end of the elastic plate 42 adheres to the side wall of the heating plate 2, thus limiting the heating plate 2 and making it stably adhere to the outer wall of the housing 1. Finally, the switch preset on the side wall of the heating plate 2 is activated, which heats the heating wire inside the heating plate 2, thereby heating the housing 1 and raising the temperature of the outdoor power supply to a suitable charging temperature.

[0052] When the outdoor power supply temperature rises, the cooling fan 161 can be activated to rotate, forming airflow inside the housing 1 and flowing out through the heat sink 16 and the through hole 15, thereby dissipating heat from the inside of the housing 1, lowering the temperature inside the outdoor power supply, and improving the service life of the outdoor power supply.

[0053] This thermal management system can heat the casing 1 by removing the heating plate 2 when the outdoor power supply is in a cold environment; it can also cool the outdoor power supply by activating the cooling fan 161 to create outward-flowing gas inside the casing 1 when the internal temperature of the outdoor power supply rises. This achieves temperature regulation of the outdoor power supply and reduces the impact of outdoor temperature on its use.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
