Description

Technical Field

[0001] This utility model relates to the field of battery heating film technology, specifically to a high-efficiency drone battery heating film. Background Technology

[0002] Drone battery heating film is a device used to preheat and keep drone batteries warm in low-temperature environments, improving flight efficiency and extending battery life. It is a flexible electrothermal element attached to the surface of the battery, which converts electrical energy into heat energy to solve the problem of performance degradation of lithium batteries in low-temperature environments. It is widely used in northern my country.

[0003] Existing heating films require an electric heater to gradually heat the film during the battery heating process, which takes a long time, is slow, and has a poor heating effect. In addition, the existing heating films are prone to causing localized overheating of the battery due to the covering method during use. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency heating film for drone batteries in order to solve the above problems. By using the slots in the PI film of the composite heating film and the heat-conducting copper wires, it is directly connected to the heating plate and heating groove in the heater, which can quickly increase the overall temperature of the PI film and rapidly heat the surface of the battery to ensure that the battery works effectively.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A high-efficiency drone battery heating film includes: a battery insulation chamber and a composite heating film. The battery insulation chamber is provided with a sealing plate and a connection port. A battery placement mechanism is fixedly provided in the battery insulation chamber. A monitoring mechanism and a heating mechanism are respectively provided in the battery insulation chamber. A command transmission line is provided between the monitoring mechanism and the heating mechanism.

[0007] The composite heating film includes a first insulating layer, a hydrophobic coating connected to the first insulating layer, a PI film connected to the hydrophobic coating, a second insulating layer connected to the PI film, and a slot formed in the PI film with a heat-conducting copper wire running through it.

[0008] Furthermore, the battery placement mechanism includes a placement groove, the placement groove having a through-wire groove and a limiting groove, the through-wire groove being longitudinally positioned and the limiting groove being transversely positioned.

[0009] Furthermore, the monitoring mechanism includes a temperature monitor, which is equipped with a control button and two temperature transmission lines, each of which is equipped with a monitoring head.

[0010] Furthermore, the heating mechanism includes a heater, the heater is provided with a conductive plate, and the conductive plate is connected to a connecting plate.

[0011] Furthermore, the connecting plate is connected to a heating plate, and the heating plate is fixedly provided with multiple heating slots.

[0012] Furthermore, the two monitoring heads penetrate the placement slot and are flush with the inner wall of the placement slot.

[0013] Furthermore, the connecting plate extends through the limiting groove.

[0014] Furthermore, the heating plate is snapped into the slot opened in the PI film, and the multiple heating slots are in contact with the heat-conducting copper wires.

[0015] Furthermore, the battery insulation compartment includes a battery compartment, which has threaded holes around its perimeter and grooves.

[0016] Furthermore, the sealing plate includes a sealing cover, and bolts are threaded through all four sides of the sealing cover.

[0017] In summary, the beneficial effects of this utility model are as follows: by using the battery placement mechanism, sealing plate, and composite heating film inside the battery insulation chamber, the battery is confined inside the battery insulation chamber, thereby improving the stability of the battery after placement.

[0018] By directly connecting the PI film and the heat-conducting copper wires inside the composite heating film with the heating plate and heating groove in the heating mechanism, the heat conduction speed inside the PI film is increased, improving the heating effect. In addition, multiple heat-conducting copper wires make the PI film flat, avoiding local overheating during battery heating.

[0019] After the staff sets two thresholds, the temperature monitor monitors the temperature inside the placement tank and the surface of the battery through the temperature transmission line and the monitoring head. When the temperature is below the threshold, the heater is started through the command transmission line to heat the battery. When the temperature is above the set threshold, the heater is closed through the command transmission line to stop heating the battery, making the product intelligent. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] See Figures 1-4As shown, this utility model provides a high-efficiency drone battery heating film, including: a battery insulation chamber 1 and a composite heating film 7. The battery insulation chamber 1 is provided with a sealing plate 2, the battery insulation chamber 1 has a connection port 3, the battery insulation chamber 1 is fixedly provided with a battery placement mechanism 4, the battery insulation chamber 1 is respectively provided with a monitoring mechanism 5 and a heating mechanism 6, and a command transmission line 8 is provided between the monitoring mechanism 5 and the heating mechanism 6.

[0032] Using the above technical solution, the battery insulation chamber 1 supports other structures and is located inside the drone shell. The battery insulation chamber 1 is sealed by a sealing plate 2, which also insulates the interior. A connection port 3 provides space for the connection cable between the battery inside the battery insulation chamber 1 and the drone. A battery placement mechanism 4 places and limits the battery. A monitoring mechanism 5 and a heating mechanism 6 are used. The monitoring mechanism 5 is set with two thresholds, one high and one low, to monitor the temperature inside the battery placement mechanism 4 and the surface of the battery, respectively, and to heat the battery surface in conjunction with the composite heating film 7. Through a command transmission line 8, when the temperature of the battery placement mechanism 4 and the battery surface monitored by the monitoring mechanism 5 is below or above the threshold, the heating mechanism 6 is directly opened or closed via the command transmission line 8. The composite heating film 7 quickly spreads the heat from the heating mechanism 6 to the battery surface, ensuring the battery temperature is maintained.

[0033] See Figure 4 and Figure 5 As shown, the composite heating film 7 includes a first insulating layer 701, the first insulating layer 701 is connected to a hydrophobic coating 702, the hydrophobic coating 702 is connected to a PI film 703, the PI film 703 is connected to a second insulating layer 705, and the PI film 703 has a slot and a heat-conducting copper wire 704 is disposed inside it.

[0034] During use, the design of two insulating layers, the first insulating layer 701 and the second insulating layer 705, prevents short circuits and also provides wear resistance. The hydrophobic coating 702 isolates the PI film 703 from cold air. The heat from the heating mechanism 6 is quickly conducted through the slots in the PI film 703 and the internal heat-conducting copper wire 704, accelerating the heating speed of the battery surface.

[0035] See Figure 4 and Figure 6 As shown, the battery placement mechanism 4 includes a placement groove 401, a wire passage groove 402, and a limiting groove 403. The wire passage groove 402 is longitudinally opened, and the limiting groove 403 is transversely opened.

[0036] In use, the placement slot 401 provides space for the battery to rest and limits its position. The wire slot 402 places the battery's connecting wires, making it easy to connect the battery and the drone with the connection port 3. The limiting slot 403 connects the heating mechanism 6 and the composite heating film 7 to each other and limits the composite heating film 7 to ensure that it covers the battery surface.

[0037] See Figures 4-7 As shown, the monitoring mechanism 5 includes a temperature monitor 501, which is equipped with a control button 502 and two temperature transmission lines 503. Each of the two temperature transmission lines 503 is equipped with a monitoring head 504. The two monitoring heads 504 pass through the placement groove 401 and are flush with the inner wall of the placement groove 401. The heating mechanism 6 includes a heater 601, which is equipped with a conductive plate 602. The conductive plate 602 is connected to a connecting plate 603. The connecting plate 603 is connected to a heating plate 604. The heating plate 604 has multiple heating slots 605 fixedly formed. The connecting plate 603 passes through the limiting groove 403. The heating plate 604 is snapped into the slot formed in the PI film 703. The multiple heating slots 605 are in contact with the heat-conducting copper wire 704.

[0038] Using the above embodiment, the dual threshold information of the temperature monitor 501, which can be transmitted, is already used in the DJI Mavic series of existing products. The threshold is set by the control button 502, and manual heating and automatic heating settings are performed simultaneously. The temperature detected by the monitoring head 504 is transmitted to the temperature monitor 501 through two temperature transmission lines 503. When the temperature is lower than the set threshold, the heater 601 is activated through the command transmission line 8. When the temperature is higher than the threshold, the heater 601 is closed. The heater 601 used for batteries is widely used in the DJI Inspire series. The heat generated by the heater 601 is conducted through the conduction plate 602 to the heating plate 604 and the heating groove 605. The heating plate 604 and the heating groove 605 are connected to the limiting groove 403 through the connecting plate 603, which facilitates the limitation of the composite heating film 7. The heating plate 604 and the heating groove 605 directly contact the slot opened in the PI film 703 and multiple heat-conducting copper wires 704 to quickly heat the PI film 703 and improve the overall heating effect of the composite heating film 7.

[0039] See Figure 3 As shown, the battery insulation chamber 1 includes a battery compartment 101, the battery compartment 101 has threaded holes 102 around its perimeter, and the battery compartment 101 has grooves 103. The sealing plate 2 includes a sealing cover 201, and bolts 202 are threaded through all four sides of the sealing cover 201.

[0040] Specifically, the battery compartment 101 and the sealing cover 201 are connected together by the threaded holes 102 around the battery compartment 101 and the bolts 202 around the sealing cover 201, so as to initially seal the groove 103 opened in the battery compartment 101.

[0041] Using the above structure, when using this product, first unscrew the multiple bolts 202 of the sealing plate 2, remove the sealing cover 201, and after removing the sealing plate 2, expose the groove 103 inside the battery insulation chamber 1. Then pull the composite heating film 7 out from the heating plate 604 and heating groove 605 in the heating mechanism 6. At this time, the battery can be directly placed into the placement groove 401 of the battery placement mechanism 4. The battery connection wire is placed on one side of the through groove 402. At the same time, the battery connection wire can extend directly from the connection port 3 to connect with the drone and provide power. Then place the composite heating film 7 on the surface of the battery and move it toward the heating mechanism 6.

[0042] Subsequently, the composite heating film 7 is connected to the connecting plate 603 and heating plate 604 in the heating mechanism 6 via the slot opened in the PI film 703 and the heat-conducting copper wire 704, and then laid flat on the battery surface to complete the battery coverage. Then, the temperature monitor 501 in the monitoring mechanism 5 is activated, and the temperature inside the placement slot 401 and on the battery surface is monitored through the two extended temperature transmission lines 503 and the monitoring head 504. The operator sets two threshold values ​​for the temperature monitor 501. When the temperature inside the placement slot 401 and on the battery surface falls below the threshold value, the heating mechanism 6 is instructed via the command transmission line 8. After the heating mechanism 6 is activated, the heating plate 604 and the heating tank 605 are heated by the heater 601 and the conduction plate 602. The connecting plate 603 is inserted into the limiting groove 403. At this time, the heating plate 604 is connected by the slot of the PI film 703 in the composite heating film 7, and the heating tank 605 is connected by the heat-conducting copper wire 704. The composite heating film 7 heats the surface of the battery to maintain the efficiency of normal battery operation. When the temperature of the battery and the placement tank 401 is too high and exceeds the set threshold, the heater 601 in the heating mechanism 6 is turned off by the temperature monitor 501 and the command transmission line 8.

[0043] The composite heating film 7 uses two insulating layers for double electrical insulation to prevent short circuits. At the same time, it works with the sealing cover 201 to squeeze the battery inside the placement groove 401. The double insulating layers also provide wear resistance. The hydrophobic coating 702 isolates the PI film 703 from cold air, improving the heating effect. In addition, the heat-conducting copper wire 704 running through the PI film 703 quickly heats other parts of the PI film 703, accelerating the heating time of the entire PI film 703 and improving the heating effect.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
