Description

Technical Field

[0001] The utility model relates to the technical field of battery modules, and specifically relates to a direct plug-in battery module. Background Technique

[0002] A direct plug-in battery module is a battery component that is convenient to directly insert or connect to a corresponding device. Using this type of battery module can quickly disassemble and assemble when replacement is needed, thus effectively reducing the work process during disassembly and assembly.

[0003] In the prior art, a Chinese patent with the authorization announcement number CN209200048U discloses a direct plug-in battery for a drone, including a battery main body. One end of the battery main body is connected with a power cord. An aluminum foil is attached to the periphery of the power cord. A braided net is annularly arranged outside the aluminum foil. A PVC outer skin is coated outside the braided net. A convex power connector is installed at one end of the power cord. An insulating strengthening plate is arranged on the top of the battery main body. One end of the insulating strengthening plate is fixedly connected with a charging plug. The battery main body is charged through the power cord. The braided net, aluminum foil and PVC outer skin ensure the strength and toughness of the power cord. The battery main body is directly connected to the charging connector inside the drone by using the charging plug at one end of the insulating strengthening plate, canceling the traditional line connection and reducing the battery load. When the charging plug is correspondingly connected to the charging interface, the limit chuck is inserted into the limit slot, so that the battery main body will not shake during installation.

[0004] The above mechanism reduces the line connection and the battery load, and uses the limit chuck for insertion, so that the battery main body will not shake during installation. However, during actual use, when the charging plug is arranged on the battery module, there will be a certain reserved space for connection with the charging port. Dust is likely to enter the battery module in the non-use state of the charging reserved port. The accumulation of dust will affect the sensitivity of the subsequent charging plug during use. At the same time, too much dust will also cause the temperature dissipation efficiency of the internal battery module to decrease during use, resulting in an increase in the temperature of the battery itself and affecting the service life of the battery. Content of the Utility Model

[0005] The purpose of the utility model is to provide a direct plug-in battery module to solve the problems that dust is likely to enter the battery module in the non-use state of the charging reserved port, the accumulation of dust will affect the sensitivity of the subsequent charging plug during use, and the heat dissipation efficiency of the battery itself is reduced as mentioned in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solution: A direct plug-in battery module, including a protective housing, the bottom end of the protective housing is snap-connected with a fixed base, a battery module body is installed inside the fixed base, and the battery module body is disposed inside the protective housing. An upper end of one side of the protective housing is provided with a charging reserved port. One side of the top end of the battery module body is fixedly connected with a charging base, and the charging base is disposed on one side of the charging reserved port;

[0007] Both ends of the upper end of one side of the protective housing are fixedly connected with fixed boxes, and a dust-proof limiting mechanism for preventing dust from entering the inside of the protective housing is disposed inside the fixed boxes. The dust-proof limiting mechanism includes a shielding plate, and the shielding plate is slidably connected inside the fixed boxes. One side of the shielding plate is fixedly connected with magnets, and the positions of the magnets correspond to each other;

[0008] The top end of the protective housing at one end of the fixed box is fixedly connected with an air storage box, and a dust removal mechanism for preventing dust accumulation on the surface of the charging base is disposed inside the air storage box.

[0009] Further, one side inside the fixed box is fixedly connected with a connecting spring, and an elastic structure is formed between the fixed box and the shielding plate through the connecting spring.

[0010] Further, the cross section of the magnet is in an inverted "L" shape, and the positions of the magnets correspond to each other.

[0011] Further, the dust-proof limiting mechanism includes an air jet port, and the air jet port is fixedly connected to the middle position of the bottom end inside the air storage box. Both sides of the air storage box are connected to the fixed box through hoses. A filter net is slidably connected inside the air storage box, and the filter net is disposed above the air jet port.

[0012] Further, a screen anti-blocking mechanism for jitter cleaning the filter net is disposed inside the air storage box. The screen anti-blocking mechanism includes fan blades, and the fan blades are rotatably connected to both sides inside the air storage box. The fan blades are disposed on one side of the hose. One end of the fan blade is rotatably connected with a cam through a pulley, and the cam is disposed above the air jet port.

[0013] Further, limiting rods are fixedly connected to four corners inside the air storage box, and the limiting rods pass through and extend to the top end of the filter net. A return spring is wound around the lower end of the outer side of the limiting rod.

[0014] Further, the bottom end of the return spring is connected to the air storage box, and the return spring is disposed below the filter net:

[0015] 1. Since the diameter of the charging reserved port is relatively large, dust can enter the interior of the protective housing through the charging reserved port when it is not in use. There is a baffle plate connected to the inside of the fixed box through a piston. The baffle plate can be used to block the charging reserved port, effectively reducing the entry of dust when it is not in use.

[0016] Furthermore, when not in use, the two baffle plates can be adsorbed and fitted together by magnets, reducing the gap between the baffle plates and preventing the gap from being generated due to the back-and-forth shaking of the connecting spring. At the same time, the magnets can also clamp and limit the charging connecting wire when the charging connecting wire is connected to the charging base for charging, preventing the charging connecting wire from loosening during use.

[0017] Even further, the connecting spring inside the fixed box can assist the baffle plate to reset its position, preventing the situation where the baffle plate cannot be reset and needs to be adjusted manually after the charging base is separated from the charging connecting wire, enabling the baffle plate to automatically fit and block when charging is not required.

[0018] 2. The movement of the baffle plate will squeeze the piston, causing the piston to transport the gas inside the fixed box to the inside of the air storage box through a hose, and then blow dust on the surface of the charging base through the air jet port below the air storage box, reducing the dust electrostatically adsorbed on the surface of the charging base.

[0019] Furthermore, the gas entering the hose will blow the fan blade to rotate, driving the cam to rotate. During the rotation of the cam, it will squeeze the air jet port below, causing the height of the air jet port to change. At the same time, the return spring below the air jet port is stressed and shortens in length. When the cam rotates to another angle, the return spring makes the air jet port constantly shake up and down through its own elastic force, thereby shaking the dust accumulated on the surface of the air jet port and preventing the dust from blocking the air jet port body.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0029] Embodiment 1:

[0030] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown in the technical solution, to solve the problem that dust easily enters the battery module, and the accumulation of dust will affect the sensitivity of the subsequent charging plug during use and reduce the heat dissipation efficiency of the battery itself: The direct plug-in battery module discloses a dust-proof limiting mechanism, including a protective housing 1, the bottom end of the protective housing 1 is snap-connected with a fixed base 2, the inside of the fixed base 2 is provided with a battery module body 3, and the battery module body 3 is arranged inside the protective housing 1. An upper end on one side of the protective housing 1 is provided with a charging reserved port 4. One side of the top end of the battery module body 3 is fixedly connected with a charging seat 5, and the charging seat 5 is arranged on one side of the charging reserved port 4. Both ends of the upper end on one side of the protective housing 1 are fixedly connected with fixed boxes 6, and a dust-proof limiting mechanism for preventing dust from entering the inside of the protective housing 1 is arranged inside the fixed boxes 6. The dust-proof limiting mechanism includes a baffle 8, and the baffle 8 is slidably connected inside the fixed box 6. One side of the baffle 8 is fixedly connected with a magnet 9, and the positions of the magnets 9 correspond to each other. One side inside the fixed box 6 is fixedly connected with a connecting spring 7, and an elastic structure is formed between the fixed box 6 and the baffle 8 through the connecting spring 7. The cross-section of the magnet 9 is in an inverted "L" shape, and the positions of the magnets 9 correspond to each other.

[0031] In this example, the battery module body 3 is installed inside the fixed base 2, the protective housing 1 is sleeved outside the fixed base 2, and the protective housing 1 and the fixed base 2 are connected to each other, so as to protect the battery module body 3, so that the battery module body 3 can be better protected by the protective housing 1 and the fixed base 2 during the formal use process, and avoid direct damage to the body caused by collision of the battery module body 3 during use;

[0032] The charging connection line can be connected to the charging base 5 through the charging reserved port 4. Since the diameter of the charging reserved port 4 is relatively large, dust will enter the inside of the protective housing 1 through the charging reserved port 4 when it is not in use. A baffle 8 is connected inside the fixed box 6 through a piston. The charging reserved port 4 can be blocked by using the baffle 8, effectively reducing the entry of dust in the non-use state. At the same time, two baffles 8 can be adsorbed and fitted to each other by a magnet 9 when not in use, so that the gap between the baffles 8 is reduced, and the generation of gaps caused by the back-and-forth shaking of the connecting spring 7 of the baffle 8 is avoided.

[0033] Embodiment Two:

[0034] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 7 shown in the technical solution, based on Embodiment One, to solve the problem that some dust enters and adheres to the surface of the charging base 5, affecting the charging sensitivity: for this direct plug-in battery module, a dust removal mechanism is disclosed. A gas storage box 11 is fixedly connected to the top end of the protective housing 1 at one end of the fixed box 6, and a dust removal mechanism for preventing dust accumulation on the surface of the charging base 5 is provided inside the gas storage box 11. The dust prevention and limiting mechanism includes a jet port 14, and the jet port 14 is fixedly connected to the middle position at the bottom end inside the gas storage box 11. Both sides of the gas storage box 11 are connected to the fixed box 6 through a hose 10. A filter net 13 is slidably connected inside the gas storage box 11, and the filter net 13 is arranged above the jet port 14.

[0035] In this example, during the process that the baffle 8 inside the fixed box 6 moves to both sides due to the charging connection line, the movement of the baffle 8 will squeeze the piston, so that the piston transports the gas inside the fixed box 6 to the inside of the gas storage box 11 through the hose 10, and then blows air to the surface of the charging base 5 through the jet port 14 below the gas storage box 11 to remove dust, reducing the dust electrostatically adsorbed on the surface of the charging base 5 and keeping the surface of the charging base 5 clean, thereby effectively avoiding the problem of decreased sensitivity of the charging base 5 during use.

[0036] Embodiment Three:

[0037] As Figure 1 、 Figure 2 、Figure 3 , Figure 6 and Figure 7 For the technical solution shown, based on the first and second embodiments, in order to solve the problem that during the process of blowing dust, when using the filter screen 13 for dust filtration, after long-term use, the filter screen 13 itself will be blocked by dust, affecting the air intake effect: The direct plug-in battery module discloses a screen anti-blocking mechanism. Inside the air storage box 11, there is a screen anti-blocking mechanism for jitter cleaning the filter screen 13. The screen anti-blocking mechanism includes a fan blade 12, and the fan blade 12 is rotatably connected to both sides inside the air storage box 11. The fan blade 12 is arranged on one side of the hose 10. One end of the fan blade 12 is rotatably connected to a cam 17 through a pulley, and the cam 17 is arranged above the air jet port 14. At the four corners inside the air storage box 11, there are fixed connection limit rods 15, and the limit rods 15 pass through and extend to the top of the filter screen 13. A return spring 16 is wound around the lower end of the outer side of the limit rod 15, and the bottom end of the return spring 16 is connected to the air storage box 11, and the return spring 16 is arranged below the filter screen 13.

[0038] In this example, through the air jet port 14, gas can be filtered during the process of blowing air through the filter screen 13, reducing the dust blown onto the surface of the charging base 5. At the same time, the entry of the gas will also blow the fan blade 12 to rotate. During the rotation of the fan blade 12, the cam 17 will be driven to rotate through the pulley. During the rotation of the cam 17, it will squeeze the lower air jet port 14, causing the height of the air jet port 14 to change. At the same time, the return spring 16 below the air jet port 14 is stressed and shortens in length. When the cam 17 rotates to another angle, the return spring 16 makes the air jet port 14 constantly shake up and down through its own elastic force, thereby shaking the dust accumulated on the surface of the air jet port 14, preventing the dust from blocking the air jet port 14 body. During the opening and closing process of the baffle plate 8, gas will enter the inside of the air storage box 11, so that the fan blade 12 can rotate due to the gas entering from different positions, thus realizing the cleaning of the dust on the surface of the air jet port 14.
