Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a battery fixing structure for UAVs. Background Technology

[0002] With the continuous development of science and technology, drone technology has been greatly improved in recent years, resulting in many intelligent and multifunctional unmanned aerial vehicles. By carrying various types of sensors, drones can achieve real-time image transmission and high-risk area detection. Currently, they are widely used in various industries, including aerial photography, surveying and mapping, plant protection, reconnaissance, and disaster relief.

[0003] According to patent number 202021283026.9, a drone battery fixing structure and a drone are provided for fixing a power source to the drone body. The drone battery fixing structure includes a power source compartment and a power source fixing mechanism. The power source fixing mechanism is installed on the power source. A push-out component is provided in the power source compartment. When the power source is fixed in the power source compartment by the power source fixing mechanism, the push-out component abuts against the power source and is in a compressed energy storage state. When the power source fixing mechanism unlocks the fixed connection between the power source and the power source compartment, the push-out component will push the power source out.

[0004] However, the battery mounting structure of this drone is too enclosed for battery protection. During the use of traditional batteries, the intense chemical reactions inside the battery during the drone's high-speed flight or continuous climb will cause it to generate heat. The enclosed mounting structure will lead to poor heat dissipation, and the temperature rise will be more significant in summer, resulting in a decline in performance. For example, it will increase the internal impedance of the battery, thereby reducing the battery's output power and energy density. Moreover, working at high temperatures will accelerate the aging process of materials, including the decomposition of electrolyte, corrosion of electrode materials and structural changes, and even the risk of thermal runaway. In order to avoid the impact of low temperatures in winter on battery performance and energy, we propose a battery mounting structure for drones. Utility Model Content

[0005] The technical problem this invention aims to solve is that battery temperature rises more significantly in summer, and that the impact of low temperatures on battery performance in winter should be avoided.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a battery fixing structure for a drone, including a connecting plate, the top of which is connected to the main body structure of the drone by bolts, a shell fixedly connected to the bottom of the connecting plate, a battery compartment for installing the battery is installed inside the shell, a number of heat dissipation holes are provided inside the shell and the heat dissipation holes communicate with the battery compartment inside the shell, a sleeve is installed on the back of the connecting plate, a connecting shaft is rotatably connected inside the sleeve, and a heat insulation frame is fixedly connected to the side of the connecting shaft, the side of the heat insulation frame and the heat dissipation holes inside the shell are engaged with each other in use.

[0007] Furthermore, the bottom of the insulation rack is set as a fence structure, and the end of the insulation rack is provided with a connecting buckle for engaging with the end of the heat dissipation hole. A locking block is installed on the side of the connecting buckle, and the outer side of the locking block is horizontally inserted into the interior of the heat dissipation hole relative to the connecting buckle.

[0008] Furthermore, the insulation rack is made of soft material and can be stretched under stress. Several sets of insulation sheets are fixedly connected to the inner wall of the insulation rack, and the insulation sheets are made of non-metallic insulation material.

[0009] Furthermore, connecting blocks are fixedly connected to both sides of the shell, and a fixed seat is fixedly connected to the side of the insulation rack via a bracket. A knob is rotatably connected inside the fixed seat, and a transmission rod is rotatably connected to the back of the knob relative to the fixed seat. A limit rod is rotatably connected to the end of the transmission rod away from the knob. The limit rod is inserted into the inside of the connecting block in the use state, and a limit ring is inserted into the outside of the limit rod. The side of the limit ring is fixedly connected to the side of the insulation rack.

[0010] Furthermore, the knob has a handle on the front of the mounting base, and the handle protrudes from the front of the knob.

[0011] Furthermore, a connecting seat is fixedly connected to the back of the knob, a sliding groove is provided inside the connecting seat, and a telescopic spring is installed at the bottom of the sliding groove. A limit pin is fixedly connected to the end of the telescopic spring, and a limit bracket is fixedly connected to the side of the housing relative to the limit pin.

[0012] Furthermore, there are two sets of transmission rods and connecting seats, and the transmission rods and connecting seats are arranged equally and crosswise on the back of the knob.

[0013] Furthermore, the end of the limiting pin is chamfered, and the contact surface of the limiting frame relative to the limiting pin is provided with a triangular groove.

[0014] The advantages of this utility model compared with the prior art are as follows: 1. This device's mounting structure departs from the traditional enclosed structure. Multiple perforations are cut out within the original enclosed structure, allowing the battery mounting structure to directly contact the air during use. In summer, airflow facilitates heat dissipation, ensuring the battery's operating temperature remains within a reasonable range. Simultaneously, the perforated structure reduces weight during summer use compared to traditional mounting structures, increasing battery range. Furthermore, in cold winter conditions, an insulation structure can be installed to completely enclose the battery, ensuring optimal operating temperature in low-temperature environments, indirectly improving battery lifespan and operational safety. 2. This device uses knobs and clips to disassemble and install the insulation structure. The operation is simple and convenient, and the dual installation and fixing method can quickly connect the insulation structure and the battery fixing structure, ensuring the stability of the connection during the drone's flight and meeting the reliability of battery insulation. It also facilitates the subsequent cleaning and maintenance of the insulation structure. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Combined with appendix Figure 1 A battery fixing structure for a drone includes a connecting plate 1. The top of the connecting plate 1 is connected to the main body of the drone via bolts. A housing 2 is fixedly connected to the bottom of the connecting plate 1. The housing 2 has a battery compartment for installing the battery. The bottom of the battery compartment is equipped with a spring clip, which can press and lock the battery in place after it is pushed into the bottom of the battery compartment. The top of the connecting plate 1 is equipped with a connecting cable for driving the drone and is connected to the docking mechanism of the battery compartment. The housing 2 has several sets of heat dissipation holes 3 inside, and the heat dissipation holes 3 communicate with the battery compartment inside the housing 2. When the drone is running in summer, cold air from outside can directly contact the battery surface through the heat dissipation holes 3 to cool it down. A sleeve 4 is installed on the back of the connecting plate 1. Figure 1 As can be seen, the sleeve 4 is set as a ring structure with a notch, and the notch is located at the upper end of the sleeve 4, so that the connecting shaft 5 can be inserted into the inside of the sleeve 4 to achieve a rotatable connection. The connecting shaft 5 is rotatably connected inside the sleeve 4, and the heat insulation frame 6 is fixedly connected to the side of the connecting shaft 5. The heat insulation frame 6 adopts a hollow structure inside to reduce its weight while ensuring the connection. The side of the heat insulation frame 6 and the heat dissipation hole 3 inside the shell 2 are interlocked in use.

[0024] Combined with appendix Figure 1 and Figure 3 When using the drone in summer, the connecting plate 1 and the shell 2 can be directly connected to the battery. In order to ensure effective cooling of the battery, it is in direct contact with the outside air through the heat dissipation holes 3 to achieve the cooling effect. In winter when the temperature is low, the operator only needs to insert the connecting shaft 5 in the insulation structure through the top port of the sleeve 4, and then flip the insulation frame 6 with the connecting shaft 5 as the center so that the insulation frame 6 fits against the outside of the shell 2. At the same time, the grid structure at the bottom of the insulation frame 6 can be fitted into the heat dissipation holes 3, thereby achieving the function of wrapping and insulating the battery, achieving the cooling effect of the battery in summer and the insulation effect of the battery in winter. The operation and installation process is quick and easy for personnel to use.

[0025] In a specific implementation of this utility model, the bottom of the heat preservation rack 6 is set as a fence structure. The width of the bottom fence of the heat preservation rack 6 is equal to the width of the heat dissipation hole 3. The two can fit together to wrap and insulate the battery. The end of the heat preservation rack 6 is provided with a connecting buckle 8 for engaging with the end of the heat dissipation hole 3. The connecting buckle 8 is a 'U' shaped structure with a locking block 9 on its side. The elastic deformation of the 'U' shaped structure can push the locking block 9 into the corresponding slot of the heat dissipation hole 3. The outer side of the locking block 9 is horizontally engaged into the interior of the heat dissipation hole 3 relative to the connecting buckle 8.

[0026] Reference Appendix Figure 4When the insulation rack 6 and the shell 2 are attached to each other, the end of the insulation rack 6 will be embedded in the interior of the shell 2. At the same time, the connecting buckle 8 will be squeezed into the corresponding slot of the shell 2 due to its own deformation elasticity. This makes the insulation rack 6 connected to the connecting buckle 8 and the side of the shell 2 fit together. When disassembling, the personnel only need to squeeze the port of the connecting buckle 8 to reduce the internal gap of the connecting buckle 8, providing lateral distance for the buckle 9 to leave the slot of the shell 2. This makes the end of the insulation rack 6 away from the connecting shaft 5 separate from the shell 2, and then the sleeve 4 separates from the connecting shaft 5, thereby realizing the separation of the insulation material body from the battery fixing structure.

[0027] In specific implementation of this utility model, the heat preservation rack 6 is made of soft material. The heat preservation rack 6 can be made of polystyrene foam, polyurethane foam, phenolic foam, etc. to achieve the heat preservation effect. The heat preservation rack 6 can be extended under force. In order to ensure that each set of grid structure can be fitted into the heat dissipation hole 3 during the flipping process, the innermost grid structure of the heat preservation rack 6 can be squeezed and deformed during the flipping process to provide conditions for the flipping space. Several sets of heat preservation sheets 7 are fixedly connected to the inner wall of the heat preservation rack 6. The heat preservation sheets 7 are made of non-metallic heat preservation material. The use of non-metallic material for the heat preservation sheets 7 can reduce the mass of the heat preservation material, reduce the battery's range consumption, and at the same time avoid the metal material from acting as a medium for battery conduction.

[0028] Combined with appendix Figure 5 and Figure 6 In a specific implementation of this utility model, connecting blocks 10 are fixedly connected to both sides of the shell 2, and a fixed seat 11 is fixedly connected to the side of the heat preservation rack 6 via a bracket. A knob 12 is rotatably connected inside the fixed seat 11. A transmission rod 13 is rotatably connected to the back of the knob 12 relative to the fixed seat 11. The connection point between the transmission rod 13 and the knob 12 is located at the edge of the knob 12. When the knob 12 rotates, it can drive the end of the connected transmission rod 13 to perform a circular motion. At the same time, the other end of the transmission rod 13 will exert a pulling effect on the limiting rod 14. The end of the transmission rod 13 away from the knob 12 is rotatably connected to the limiting rod 14. The limiting rod 14 is inserted into the connecting block 10 in the use state. A limiting ring 15 is inserted into the outside of the limiting rod 14, and the side of the limiting ring 15 is fixedly connected to the side of the heat preservation rack 6. The setting of the limiting ring 15 can limit the movement of the limiting rod 14, so that the limiting rod 14 can only move laterally.

[0029] To ensure a tight connection between the insulation rack 6 and the housing 2, after the initial connection, the operator can rotate the knob 12 inside the fixing base 11 to make the end of the transmission rod 13 connected to the edge of the knob 12 rotate. Then, the limiting rod 14 connected to the other end of the transmission rod 13 will be inserted into the interior of the connecting block 10. Since the connecting block 10 is fixed to the housing 2, the connection between the limiting rod 14 and the connecting block 10 further stabilizes the connection between the insulation rack 6 and the housing 2. When disassembling, the knob 12 is rotated in the opposite direction to separate the limiting rod 14 from the connecting block 10.

[0030] In a specific implementation of this utility model, the knob 12 is provided with a handle on the front of the fixed base 11, and the handle protrudes from the front of the knob 12. Personnel can rotate the knob 12 to drive the transmission rod 13 on the back of the knob 12 to deflect, thereby realizing the transmission of power.

[0031] In a specific implementation of this utility model, a connecting seat 16 is fixedly connected to the back of the knob 12. The connecting seat 16 has a sliding groove inside, and a telescopic spring 17 is installed at the bottom of the sliding groove. A limit pin 18 is fixedly connected to the end of the telescopic spring 17. The elastic force of the connecting seat 16 can push the limit pin 18 and fit it against the limit frame 19, so that the limit pin 18 will not move when it is only subjected to the elastic force of the telescopic spring 17. The side of the housing 2 is fixedly connected to the limit frame 19 relative to the position of the limit pin 18.

[0032] Reference Appendix Figure 5 When the limiting rod 14 is connected to the connecting block 10, in order to maintain its state, it is necessary to ensure that the relative position of the fixed seat 11 and the knob 12 remains unchanged. When the back of the knob 12 is in a horizontal state, the two sets of connecting seats 16 are closest to the limiting frame 19 in the vertical direction, and the elastic force of the telescopic spring 17 pushes the limiting pin 18 to be inserted into the triangular groove of the limiting frame 19, thereby fixing the position of the fixed seat 11 and the knob 12, and indirectly ensuring the stable connection between the limiting rod 14 and the connecting block 10.

[0033] In a specific implementation of this utility model, two sets of transmission rods 13 and connecting seats 16 are provided, and the transmission rods 13 and connecting seats 16 are equally and crosswise arranged on the back of the knob 12 to ensure that the connecting seats 16 will not affect the deflection of the transmission rods 13 during rotation, and to reserve space for the end of the transmission rods 13 to move in a circular motion with the knob 12.

[0034] In a specific implementation of this utility model, the end of the limiting pin 18 is provided with a chamfered structure, and the contact surface of the limiting frame 19 relative to the limiting pin 18 is provided with a triangular groove. When connected, the knob 12 can be limited so that the knob 12 is fixed in position relative to the fixing seat 11.

[0035] The working principle of this utility model is as follows: When using the drone in summer, the connecting plate 1 and the shell 2 can be directly connected to the battery. In order to ensure effective cooling of the battery, the heat dissipation hole 3 is used to directly contact the outside air to cool the battery. In winter when the temperature is low, the operator only needs to insert the connecting shaft 5 in the insulation structure through the top port of the sleeve 4, and then flip the insulation frame 6 with the connecting shaft 5 as the center so that the insulation frame 6 fits against the outside of the shell 2. At the same time, the grid structure at the bottom of the insulation frame 6 can be fitted into the heat dissipation hole 3. Then, the connecting buckle 8 and the locking block 9 at the end of the insulation frame 6 are used to lock into the side slot of the heat dissipation hole 3, so that the insulation frame 6 and the shell 2 are locked together, thereby achieving the function of wrapping and insulating the battery. This achieves the cooling effect of the battery in summer and the insulation effect of the battery in winter. The operation and installation process is quick and easy for operators to use.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
