Description

Technical Field

[0001] This utility model relates to the field of UAV environmental mapping technology, and in particular to a low-temperature protection device for batteries used in UAV environmental mapping. Background Technology

[0002] In the field of environmental remediation and green development technology research, drones, with their high efficiency and flexibility, have become an important tool for collecting geospatial data using sensors. When drones are conducting environmental mapping operations, the battery serves as the power source, and its performance directly affects the drone's endurance and operational stability.

[0003] However, in low-temperature environments, drone battery performance degrades, making them highly susceptible to low-temperature failure. For example, in scenarios such as ecological environment monitoring in cold regions and topographic mapping in high-altitude areas, low temperatures can reduce the rate of internal chemical reactions in the battery, significantly decrease capacity, and reduce discharge performance. This can shorten the drone's flight time and even lead to mid-flight power outages or crashes. This not only interrupts mapping operations and affects the continuity of data collection in environmental remediation projects but may also damage the drone and its onboard mapping equipment, increasing project costs.

[0004] In view of this, the present invention provides a new solution to the above problems. Utility Model Content

Detailed Implementation

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Example: A low-temperature protection device for batteries used in UAV environmental mapping, such as... Figure 1 , 2 As shown, it includes a housing, a heating component, a baffle 5, a drive component, and a controller. The heating component and the drive component are both electrically connected to the controller.

[0038] The shell is made of lightweight, heat-insulating material and has an overall rectangular structure. Internally, it has a cavity that matches the shape of the drone's battery 3, allowing the battery 3 to be tightly inserted into the cavity for detachable installation within the shell. The inner wall of the insulated shell is lined with an aluminum foil reflective layer, which effectively reflects heat generated by the battery 3 and the heating components, reducing heat loss.

[0039] Preferably, the housing includes a frame 101, a top cover 102, and a bottom cover 103. The top cover 102 is located on top of the frame 101 and is detachably connected to it, and the bottom cover 103 is located on the bottom of the frame 101 and is detachably connected to it.

[0040] Specifically, the top cover 102 and the bottom cover 103 are both connected to the frame 101 by screws.

[0041] Specifically, both the top cover 102 and the bottom cover 103 are integrally connected with support ears 104. There are four support ears 104, which are located at the four corners of the top cover 102 and the bottom cover 103. The support ears 104 are provided with mounting holes for mounting bolts or screws, so that the shell can be detachably connected to the drone body through the support ears 104.

[0042] It should be noted that, generally speaking, the connection between the battery 3 low-temperature protection device and the drone body can be achieved simply by setting mounting holes on the bottom cover 103. However, in order to improve the connection stability between the battery 3 low-temperature protection device and the drone body and / or to allow the battery 3 low-temperature protection device to better adapt to the installation space of different drone bodies, this utility model provides mounting holes on both the top cover 102 and the bottom cover 103. Operators can choose to fix the device on the top cover 102 and / or the bottom cover 103 according to actual installation needs, which greatly improves the flexibility of installation.

[0043] In the above technical solution, the aluminum foil reflective layer attached to the inner wall of the casing can efficiently reflect the heat generated by the battery 3 and the heating components, greatly reducing heat loss to the outside. This allows a relatively stable heat preservation environment to be formed inside the casing, enhancing the heat preservation effect of the battery 3, extending the effective working time of the battery 3 in low-temperature environments, and providing reliable power support for long-term environmental mapping operations of the UAV. In addition, regarding the assembly and maintenance of the casing, the casing consists of a frame 101, a top cover 102, and a bottom cover 103, and both the top cover 102 and the bottom cover 103 are detachably connected to the frame 101 by screws. This structural design brings many conveniences. When it is necessary to inspect the heating components inside the casing or replace the battery 3, the top cover 102 or the bottom cover 103 can be removed simply by unscrewing the screws. The operation is simple and convenient, reducing maintenance costs and time costs, and improving the practicality of the device.

[0044] Reference Figure 2 , 3 The housing contains limiting blocks 8 for securing the battery. Each limiting block 8 includes a symmetrically arranged first limiting block 81 and second limiting block 82, located in the included angle regions on adjacent sides of the battery 3. Two first limiting blocks 81 and two limiting blocks 82 are provided, each located in one of the four included angle regions of the battery 3, forming a receiving cavity for accommodating the battery 3. Both the first limiting blocks 81 and the second limiting blocks 82 are fixed to the bottom cover 103.

[0045] Specifically, the first limiting block 81 is an "L"-shaped block located at the angle between the two adjacent sides of the battery 3, and the second limiting block 82 is in contact with the inner wall of the frame 101, so that the first limiting block 81, the second limiting block 82 and the frame 101 enclose and form a receiving cavity for accommodating the battery 3.

[0046] To limit the movement of the battery 3 within the casing, preferably, the height of the frame 101 is consistent with the thickness of the battery 3, so that the battery 3 is vertically and vertically limited by the top cover 102 and the bottom cover 103.

[0047] In the above technical solution, the first limiting block 81, the second limiting block 82, and the frame 101 form a receiving cavity, which can limit the battery 3 from all sides. In addition, the height of the frame 101 is consistent with the thickness of the battery 3, and together with the top cover 102 and the bottom cover 103, the battery 3 is limited vertically, thus achieving all-round limiting and fixing of the battery 3. This can limit the shaking of the battery 3 within the casing to the greatest extent and ensure its stable performance.

[0048] Furthermore, this limiting structure design is simple, with both the first limiting block 81 and the second limiting block 82 fixed to the bottom cover 103, facilitating manufacturing and installation. Simultaneously, the all-around limiting and fixing reduces collision and friction between the battery 3 and internal components of the housing, lowering the risk of damage to the battery 3 and internal components, extending the service life of the device and battery 3, and better ensuring the stable operation of the UAV in environmental mapping operations, meeting the needs of long-term reliable operation of UAVs in environmental remediation and green development technology research.

[0049] Reference Figure 1-3 The heating assembly is located inside the housing and is used to preheat the battery 3. The heating assembly includes a heating element 41 and a temperature sensor 42. The temperature sensor 42 is installed on the inner wall of the housing and close to the battery 3. The temperature sensor 42 is used to detect the temperature inside the housing. Both the heating element 41 and the temperature sensor 42 are electrically connected to the controller. The heating element 41 is used to preheat the battery 3. Preferably, the heating element 41 is a flexible heating sheet, which is attached to the side of the battery 3 or to the inner wall of the housing. Most preferably, the flexible heating sheet is attached to the side of the battery 3.

[0050] Specifically, the flexible heating element is a silicone heating film (silicone heating element).

[0051] In the above technical solution, the flexible heating element uses a silicone heating film and is attached to both sides of the battery 3. The flexible heating element is connected to the controller via wires, and the temperature sensor 42 can monitor the temperature inside the casing in real time. When the detected temperature is below 15°C, the flexible heating element is automatically activated; when the temperature reaches 25°C, the flexible heating element is stopped, so that the battery 3 is in a suitable temperature environment.

[0052] The temperature sensor 42 in the heating assembly is installed on the inner wall of the housing and close to the battery 3. It can accurately and in real time detect the temperature inside the housing, especially the temperature around the battery 3. When the detected temperature is lower than the set value (15°C), the temperature sensor 42 transmits a signal to the controller, which then controls the heating element 41 to work. When the temperature reaches the appropriate range, it can promptly control the heating element 41 to stop, thus achieving precise control of the preheating temperature of the battery 3. This avoids underheating or overheating, ensuring that the battery 3 can quickly and stably reach the appropriate operating temperature. It effectively solves the problem of the battery 3 being difficult to start or experiencing performance degradation due to excessively low temperature in low-temperature environments.

[0053] The flexible heating element has excellent flexibility, allowing it to fit tightly against the side of battery 3, increasing the contact area and enabling heat to be transferred to battery 3 more directly and evenly. This significantly improves heating efficiency and shortens the preheating time of battery 3. Simultaneously, the flexible heating element made of silicone heating film features uniform heating, good stability, and a long service life, maintaining good heating performance during long-term use and ensuring the continuity and reliability of the preheating effect on battery 3.

[0054] Reference Figure 1-4 The housing has heat dissipation holes 2, which are grid-type heat dissipation holes located on one side of the frame 101. A baffle 5 is located inside the housing and is used to close the heat dissipation holes 2. The baffle 5 contacts the inner wall of the housing and slides against it. The grid-type heat dissipation holes 2 are located on one side of the frame 101. The grid structure can ensure effective air circulation between the inside and outside of the housing, achieving good heat dissipation, and can also block external dust and debris from entering the housing to a certain extent, reducing contamination of the battery 3 and heating components, and ensuring the normal operation of the components.

[0055] Preferably, a groove 9 is provided on the inner side of the frame 101, and a slider adapted to the groove 9 is provided on the baffle 5. The slider is embedded in the groove 9 and slides in cooperation with the groove 9.

[0056] Preferably, the drive assembly is used to drive the baffle 5 to move horizontally, so as to close or open the heat dissipation hole 2 through the baffle 5. The horizontal movement direction of the baffle 5 is consistent with the length direction of the slide 9. The drive assembly includes a cylinder 61, a mounting base 62, and an end plate 63. The mounting base 62 is fixed inside the frame 101, the cylinder 61 is mounted inside the housing through the mounting base 62, the end plate 63 is fixed to the end of the piston rod of the cylinder 61, a fixing block 7 is fixed on the baffle 5, and the end plate 63 is connected to the fixing block 7 by screws. The cylinder 61 is electrically connected to the controller.

[0057] In the above technical solution, the slider on the baffle 5 is embedded in the groove 9 and slides with the groove 9, so that the baffle 5 can move horizontally and stably along the length of the groove 9. This ensures that the baffle 5 moves smoothly when closing or opening the heat dissipation hole 2, avoiding jamming or displacement, and ensuring precise control of the opening and closing state of the heat dissipation hole 2. After the cylinder 61 is electrically connected to the controller, the controller can automatically control the cylinder 61 to work according to the temperature inside the housing, thereby driving the baffle 5 to move horizontally to close or open the heat dissipation hole 2. When the temperature inside the housing is detected to be too high (which can be set to 28℃ or 30℃), the controller controls the cylinder 61 to drive the baffle 5 to open the heat dissipation hole 2, accelerating heat dissipation; when the temperature drops to a suitable range (which can be set to 25℃), the controller controls the cylinder 61 to drive the baffle 5 to close the heat dissipation hole 2, reducing heat loss. This automatic adjustment method requires no manual intervention, responds quickly, and can adjust in real time according to the operating temperature of the battery 3, ensuring that the battery 3 is always in a suitable temperature environment, improving the stability and reliability of the UAV in environmental mapping operations.

[0058] In summary, the shell of this invention forms a closed space to reduce environmental interference, and the heating component specifically preheats the battery 3, solving the problem of low-temperature capacity decay and ensuring stable drone endurance. It also addresses the issue of battery 3 performance degradation in low-temperature environments. The heat dissipation holes 2, along with the baffle 5 and drive components, constitute a dynamic adjustment system. At high temperatures, the holes automatically open to dissipate heat and prevent the battery 3 from overheating; at low temperatures, the holes close to retain heat, adapting to complex operating scenarios such as cold and high temperatures and ensuring stable battery 3 performance.

All technical solutions falling within the scope of this utility model's concept are within its protection scope.
