[0002] Lithium polymer battery, also known as polymer lithium battery, is a chemical battery. Compared with previous batteries, it has the characteristics of high energy, miniaturization and light weight. Batteries using polymer electrolytes do not need metal shells as protective packaging, and polymer batteries are 40% lighter than steel shell lithium batteries of the same capacity and 20% lighter than aluminum shell batteries. Therefore, this polymer lithium battery that supports large discharge current has become an ideal choice for remote control models. In order to give full play to the advantages of polymer lithium-ion batteries and the characteristics of aerial operations, we have proposed a lightweight battery protective shell to meet the use of drones. Utility Model Content

[0003] The main purpose of the utility model is to provide a light-weight battery protection shell, which can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a lightweight battery protection shell, including a drone and an outer shell, the left and right inner walls of the outer shell are fixedly connected with side panels, the lower ends of the side panels are provided with limiting grooves near the front and rear sides, the inside of the limiting grooves are slidably connected with limiting blocks, an H-shaped inner shell is fixedly connected between the limiting blocks, the ends close to the side panels are fixedly connected with fixed shafts near the middle of the lower side, the outer side of the fixed shaft is rotatably connected with a support member, the front and rear ends of the support member are both against the lower end of the H-shaped inner shell, the side panels are provided with slide grooves at the corresponding support members, and two groups of symmetrical L-shaped sliding blocks are slidably installed inside the slide grooves, the L-shaped sliding blocks respectively against the front and rear ends of the lower end of the support member, and a double-headed damping rod is fixedly connected between the two groups of L-shaped sliding blocks.

[0006] Preferably, the front end of the outer shell is provided with card slots at the left and right ends close to the upper side, and the lower end of the bottom plate of the drone is provided with a second card member at the corresponding card slot, and the inner bottom of the card slot is fixedly connected with an elastic member, and the second card member is engaged with the card slot through the pressing action of the elastic member.

[0009] Preferably, a plurality of groups of evenly distributed grille holes are provided at both the front and rear ends of the outer shell.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. When installing the outer shell, no metal parts such as bolts are required. Not only is the installation and fixing simple and convenient, but the outer shell and H-shaped inner shell and other structures are made of plastic, which further reduces the structural weight and is beneficial to the flight effect of the drone. When installing the H-shaped inner shell and the polymer lithium-ion battery, you only need to pinch the two sets of L-shaped sliders to the middle, align the limit block of the H-shaped inner shell with the limit groove, and then snap it upward and push it against the upper end. The whole process is convenient and fast. The same is true for disassembly. For example, when using the drone for continuous operation, this method can be used to quickly replace the polymer lithium-ion battery, which improves the user experience.

[0012] 2. Through the frame design methods such as slotting and hollowing, the weight of the device is greatly reduced, and the cruising range of the drone is improved. At the same time, when the drone is flying in the air, the airflow can enter the interior of the outer shell through the grille holes, which not only reduces the wind resistance, but also the outside of the polymer lithium-ion battery is mostly not in contact with other structures, making the heat dissipation effect of the polymer lithium-ion battery more ideal, thereby improving the service life of the polymer lithium-ion battery.

[0013] 3. When the polymer lithium-ion battery bulges after long-term use, the detection spring contracts under force, thereby providing a buffer space for the bulging polymer lithium-ion battery to avoid rupture due to strong squeezing. At the same time, when the rebound of the detection spring reaches a certain force, it can be detected by the pressure sensor, so as to notify the user to replace and repair it in time by sending signals, which is more humane.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-Figure 4 As shown, a light-weight battery protective shell comprises a drone 1 and an outer shell 2, the left and right inner walls of the outer shell 2 are fixedly connected with side panels 9, the lower ends of the side panels 9 are provided with limiting grooves 10 near the front and rear sides, the insides of the limiting grooves 10 are slidably connected with limiting blocks 8, an H-shaped inner shell 7 is fixedly connected between the limiting blocks 8, the adjacent ends of the side panels 9 are fixedly connected with fixed shafts 11 near the middle of the lower side, the outer side of the fixed shaft 11 is rotatably connected with a support member 12, the front and rear ends of the support member 12 are both against the lower end of the H-shaped inner shell 7, the side panels 9 are provided with slide grooves 13 at the corresponding support members 12, two groups of symmetrical L-shaped sliders 14 are slidably installed inside the slide grooves 13, the L-shaped sliders 14 are respectively against the front and rear ends of the lower end of the support member 12, and a double-headed damping rod 15 is fixedly connected between the two groups of L-shaped sliders 14.

[0021] The upper end of the outer shell 2 is fixedly connected with a first clamp 3 at the left and right ends near the rear side, and the first clamp 3 is engaged with the strip groove of the bottom plate of the drone 1. The front end of the outer shell 2 is provided with a clamping slot 6 at the left and right ends near the upper side, and the lower end of the bottom plate of the drone 1 is provided with a second clamp 4 at the corresponding clamping slot 6. The inner bottom of the clamping slot 6 is fixedly connected with an elastic member 5, and the second clamp 4 is engaged with the clamping slot 6 through the pressing action of the elastic member 5. The first clamp 3 is first engaged with the strip groove of the bottom plate of the drone 1 by tilting at a certain angle, and then the second clamp 4 is inserted into the inside of the clamping slot 6, and the second clamp 4 is pressed by the elastic member 5 to provide a limiting support, thereby completing the fixed installation between the outer shell 2 and the drone 1. Conversely, no metal parts such as bolts are required, not only is the installation and fixing simple and convenient, but also the outer shell 2 and the H-shaped inner shell 7 and other structures are made of plastic, which further reduces the structural weight, which is beneficial to the flight effect of the drone 1.

[0022] The inner top wall of the outer shell 2 is fixedly connected with a sleeve 16 near the middle of the left and right sides, and the lower end of the sleeve 16 is slidably connected with a slide bar 17. A pressure plate 18 is fixedly connected between the lower ends of the slide bar 17. The lower end of the pressure plate 18 fits between the polymer lithium-ion battery placed inside the H-shaped inner shell 7. The upper end of the polymer lithium-ion battery can be limited and supported by the pressure plate 18 to avoid shaking. At the same time, since the polymer lithium-ion battery may bulge after long-term use, an upward force will be applied to the pressure plate 18 to make the slide bar 17 slide upward, and the detection spring 19 will shrink under the force, thereby providing a buffer space for the bulging polymer lithium-ion battery to avoid rupture due to strong squeezing.

[0023] A detection spring 19 is provided at the upper end of the slide rod 17 inside the sleeve 16, and a pressure sensor 20 is fixedly installed at the upper end of the detection spring 19 inside the sleeve 16. When the rebound of the detection spring 19 reaches a certain force, it can be detected by the pressure sensor 20, so as to notify the user to replace and repair it in time by sending signals, etc., which is more humane.

[0024] A plurality of groups of evenly distributed grille holes 21 are provided at both the front and rear ends of the outer shell 2. The weight of the device is greatly reduced through frame design methods such as slotting and hollowing, and the cruising range of the drone 1 is improved. At the same time, when the drone 1 is flying in the air, air can enter the interior of the outer shell 2 through the grille holes 21, and the outside of the polymer lithium-ion battery is mostly not in contact with other structures, so that the heat dissipation effect of the polymer lithium-ion battery is more ideal, thereby improving the service life of the polymer lithium-ion battery.

[0025] Working principle:

[0026] When in use, the first clamping member 3 is first engaged with the strip groove of the bottom plate of the drone 1 by tilting at a certain angle, and then the second clamping member 4 is clamped into the inside of the clamping slot 6, and the second clamping member 4 is pressed against by the elastic member 5 to provide a limiting support, thereby completing the fixed installation between the outer shell 2 and the drone 1. Conversely, no metal parts such as bolts are required, which is not only simple and convenient to install and fix, but also the outer shell 2 and the H-shaped inner shell 7 and other structures are made of plastic, which further reduces the structural weight and is beneficial to the flight effect of the drone 1. By placing the polymer lithium-ion battery inside the H-shaped inner shell 7, during installation, by pinching the two sets of L-shaped sliders 14 toward the middle, The double-headed damping rod 15 is retracted toward the middle, thereby releasing the limiting effect of the L-shaped slider 14 on the support member 12, and then the two ends of the support member 12 can be rotated downward to release the blocking effect on the limit block 8, and then the limit block 8 of the H-shaped inner shell 7 is aligned with the limit groove 10 and inserted upward. After reaching the upper end, the L-shaped slider 14 is reset under the rebound of the double-headed damping rod 15, thereby driving the support member 12 to rotate to the horizontal position again, and the support member 12 is supported by the L-shaped slider 14, and the H-shaped inner shell 7 is supported by the support member 12, and the limiting effect between the limit block 8 and the limit groove 10 is cooperated, thereby completing the fixing of the polymer lithium-ion battery. The whole process is convenient and quick, and the disassembly is similar. For example, when the drone 1 is used for continuous operation, the polymer lithium-ion battery can be quickly replaced by this method, which improves the user experience. The weight of the device is greatly reduced by the frame design methods such as slotting and hollowing, which improves the cruising range of the drone 1. At the same time, when the drone 1 is flying in the air, the airflow can enter the interior of the outer shell 2 through the grille holes 21, which not only reduces the wind resistance, but also the exterior of the polymer lithium-ion battery is mostly not in contact with other structures, so that the heat dissipation effect of the polymer lithium-ion battery is more ideal, and the service life of the polymer lithium-ion battery is improved. In addition, the upper end of the polymer lithium-ion battery can be limited and supported by the pressure plate 18 to avoid shaking. At the same time, since the polymer lithium-ion battery may swell after long-term use, an upward force will be applied to the pressure plate 18 to make the slide bar 17 slide upward, and the detection spring 19 will shrink under the force, thereby providing a buffer space for the swollen polymer lithium-ion battery to avoid rupture due to strong squeezing. At the same time, when the rebound of the detection spring 19 reaches a certain force, it can be detected by the pressure sensor 20, so as to notify the user of timely replacement and maintenance by sending signals, which is more humane.
