Description

[Technical field]

[0001] The invention relates to the technical field of charging, in particular to a pressurized charger for a solid-state battery of an unmanned aerial vehicle. [Background technology]

[0002] Lithium metal solid-state batteries have attracted close attention in the aerospace field due to their unique high energy density, such as drone products. However, there are very few successful commercial applications of lithium metal solid-state batteries in drone products, mainly due to the working mechanism of lithium metal solid-state batteries, which is that Li+ is deintercalated from the porous positive electrode side, passes through the solid electrolyte layer, and deposits on the negative electrode surface to form lithium metal. Since the lithium metal negative electrode is a flat structure rather than a porous structure of graphite, during the cycle, the free state charging method will make the Li+ deposition loose and uneven, resulting in an increase in thickness, which will directly affect the cycle stability and volume energy density of the battery cell.

[0003] In the prior art, in order to solve the problem of increased thickness due to volume change of solid-state batteries, a fixed pressurized structure is added to the outer periphery of the solid-state battery to ensure that the volume of the solid-state battery does not change. However, the increase in weight and volume caused by the pressurized structure greatly weakens the advantage of high energy density of solid-state batteries and reduces the endurance of drones. Based on the above problems, the application of lithium metal solid-state batteries in drone products is seriously affected. [Summary of the invention]

[0004] The purpose of the present invention is to provide a pressurized charger for UAV solid-state batteries, which can solve the problem of increased thickness of UAV solid-state batteries during charging, as well as the problems of low energy density and insufficient battery life, so as to enable UAV solid-state batteries to give full play to the advantages of high energy density and improve the battery life of UAVs.

[0005] In order to achieve the above-mentioned objectives, the present invention adopts the following technical solutions: a pressurized charger for a solid-state battery of a drone, used for charging a solid-state battery of a drone, comprising a shell, a circuit board and a storage unit, wherein the circuit board is arranged in the shell, has a power input terminal, and is used for charging the solid-state battery of the drone; the storage unit is arranged relative to the circuit board; the storage unit comprises a battery rack, a mounting seat and a transmission assembly, the battery rack is provided with a first accommodating space for storing solid-state batteries; the mounting seat is fixedly connected to the battery rack, and is provided with a second accommodating space, and the second accommodating space is connected to the first accommodating space; the transmission assembly is arranged on the mounting seat, and the transmission assembly partially extends out of the second accommodating space and moves toward the first accommodating space to pressurize and fix the solid-state battery of the drone.

[0006] Compared with the prior art, the UAV solid-state battery pressurized charger connects the second accommodation space in the mounting seat with the first accommodation space in the battery rack by setting the mounting seat and the transmission assembly, and then controls the transmission assembly to partially extend out of the second accommodation space and move toward the first accommodation space, thereby pressurizing and fixing the UAV solid-state battery. This setting scheme can ensure that the UAV solid-state battery is subjected to the pressure applied by the battery rack and the transmission assembly during the charging process. The pressurized charging can effectively ensure that Li+ is evenly deposited in the flat plate structure and the consistency of the battery cell thickness. The UAV solid-state battery can be installed smoothly and avoids the safety hazards caused by the continuous change of thickness.

[0007] At the same time, the drone solid-state battery does not need any additional fixed pressurized structure, and can give full play to the volume energy density advantage of lithium metal solid-state batteries, which can achieve the huge application value of doubling the endurance of existing drones. Based on this, lithium metal solid-state batteries will be widely used in drones, successfully combining the two in a benign way, and further promoting the common development of the drone industry and the lithium metal solid-state battery industry.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The drone solid-state battery pressurized charger 100 is used to charge the drone solid-state battery 200, and includes a shell 1, a circuit board 3 and a storage unit 5. The circuit board 3 is arranged in the shell 1, and has a power input terminal 31, which is used to charge the drone solid-state battery; the storage unit 5 is arranged relative to the circuit board 3; the storage unit 5 includes a battery rack 51, a mounting seat 53 and a transmission assembly 55, the battery rack 51 is provided with a first accommodating space 501, which is used to store the drone solid-state battery 200; the mounting seat 53 is fixedly connected to the battery rack 51, and is provided with a second accommodating space 503, and the second accommodating space 503 is connected to the first accommodating space 501; the transmission assembly 55 is arranged on the mounting seat 53, and the transmission assembly 55 partially extends out of the second accommodating space 503, moves toward the first accommodating space 501, and pressurizes and fixes the drone solid-state battery 200. The transmission component 55 ensures that the drone solid-state battery 200 is subjected to the pressure jointly applied by the battery rack 51 and the transmission component 55 during the charging process, which can effectively ensure that Li+ is evenly deposited in the flat structure and the thickness of the battery cell is consistent, thereby greatly improving the service life and volume energy density of the lithium metal solid-state battery.

[0017] In this embodiment, two storage units 5 are provided in the housing 1, and the two storage units 5 are arranged at intervals, and the internal structure is basically the same, so that the two drone solid-state batteries 200 can be charged at the same time, thereby improving the efficiency of single charging. Of course, in another embodiment, different numbers of storage units 5 can also be provided, such as storing one alone, or multiple intervals, and correspondingly, the same number of power input terminals 31 can be provided on the circuit board 3, and no restriction is made here. The power input terminal 31 is provided at the position of the circuit board 3 corresponding to the battery rack 51, so as to ensure that the drone solid-state battery 200 can be docked with the power input terminal when it is inserted into the battery rack 51, without the need for additional adjustment, which is very convenient. Of course, a display module (not shown) can also be provided on the housing 1, and the display module is electrically connected to the circuit board 3 to display the remaining power of the drone solid-state battery 200, so as to facilitate monitoring and reminding the user of the charging status of the drone solid-state battery 200.

[0018] The transmission assembly 55 can be implemented in a variety of ways. In this embodiment, a transmission method in which a worm 551 cooperates with a worm wheel 553 is preferred. The transmission assembly 55 includes a worm 551 and a worm wheel 553. The worm 551 is disposed on the mounting seat 53. The worm wheel 553 is movably connected to the worm 551 and the battery rack 51, respectively. The worm wheel 553 is an eccentric wheel structure. The rotation of the worm 551 drives the worm wheel 553 to rotate relative to the battery rack 51. When the worm 551 is controlled to rotate, the worm wheel 553 and the worm 551 are transmitted by meshing. Since the worm wheel 553 is an eccentric wheel, as the worm wheel 553 rotates relative to the battery rack 51, part of the structure of the worm wheel 553 will move from the second accommodation space 503 to the first accommodation space 501, and apply pressure to the drone solid-state battery 200. This arrangement is simple and stable in structure, not only saves space, but also limits the rotation of the worm wheel 553 through the worm 551, so that the force applied to the drone solid-state battery 200 is uniform and stable. During installation, the worm 551 can be controlled to rotate to a preset position. During charging, due to the limitation of the worm 551, the worm wheel 553 will not rotate randomly, and is very stable.

[0019] In this embodiment, the number of the worm 551 is one, and the number of the worm wheels 553 is two. The two worm wheels 553 are arranged side by side in the first accommodating space 501, and are movably connected to the worm 551 and the battery rack 51. The two worm wheels 553 can make the force applied to the drone solid-state battery 200 more uniform. It should be noted that the number of the worm wheels 553 can also be more than two, and the area for applying pressure is increased, which depends on the specific structural setting and is not further limited here. Of course, the number of the worm 551 can also be more than one. The worm 551 arranged at intervals can make the multiple worm wheels 553 not only arranged side by side under one worm 551, but also arranged horizontally, so that the pressure applied is more uniform.

[0020] Please continue to refer to Figure 5 and Figure 6In this embodiment, the worm wheel 553 includes a main body 5531, a toothed portion 5533, a rotating shaft 5535 and a crimping portion 5537. The toothed portion 5533 is arranged on the peripheral side of the main body 5531 relative to the worm 551. The rotating shaft 5535 is arranged on both sides of the main body 5531 and is movably connected to the battery rack 51 to ensure that the worm wheel 553 can rotate relative to the battery rack 51. The crimping portion 5537 is arranged on the peripheral side of the main body 5531 close to the battery rack 51 relative to the toothed portion 5533. The main body 5531 realizes the rotation of the worm wheel 553 as a whole relative to the battery rack 51 through the rotating shaft 5535, so that the crimping portion 5537 follows the rotation of the main body 5531 and moves from the second accommodating space 503 toward or away from the first accommodating space 501, thereby adjusting the pressure applied to the drone fixed battery 200. The main body 5531, the toothed portion 5533, the rotating shaft 5535 and the crimping portion 5537 cooperate with each other to effectively convert the rotating force of the worm 551 into a pressure applied vertically to fix the battery 200 on the drone. The structural design is ingenious and labor-saving.

[0021] In order to save processing costs, the toothed portion 5533 is arranged in a certain preset area around the main body 5531, and the setting of the preset area is related to the setting of the crimping portion 5537. Specifically, the arc of the toothed portion 5533 relative to the center of the main body 5531 is greater than or equal to the arc of the crimping portion 5537 relative to the center of the main body 5531, and the two are arranged at both ends of the center of the main body 5531. Combined with the working principle of the drone solid-state battery pressurized charger 100, further explanation:

[0022] During the installation of the drone solid-state battery 200, the worm 551 and the worm wheel 553 are meshed at one end of the meshing portion 5533; during the pressing stage, the crimping portion 5537 starts to gradually increase in force from being unforced. If the crimping portion 5537 is pressed at the point farthest from the center of the main body 5531 and the force reaches the maximum, the worm 551 and the worm wheel 553 are meshed at the other end of the meshing portion 5533.

[0023] Of course, in general, the toothed portion 5533 is relatively more provided to reserve a certain range to protect the main body 5531. That is, the arc of the toothed portion 5533 relative to the center of the main body 5531 is slightly larger than the arc of the crimping portion 5537 relative to the center of the main body 5531, which can not only realize effective force transmission, but also save processing costs.

[0024] In this embodiment, the crimping portion 5537 is provided separately from the main body 5531. The crimping portion 5537 is installed separately on the peripheral side of the main body 5531 close to the battery rack 51. The crimping portion 5537 relatively protrudes from the main body 5531 and can be used to apply pressure. After long-term use, the crimping portion 5537 is prone to wear. In this case, the crimping portion 5537 can be replaced separately without replacing the entire worm gear 553, saving maintenance costs. The crimping portion 5537 is configured as a roller structure, which is embedded in the circumferential side of the main body 5531 close to the battery rack 51. The crimping portion 5537 can rotate relative to the main body 5531. In the clamping stage, the axis of the crimping portion 5537 rotates with the main body 5531, but the force point of the crimping portion 5537 remains unchanged. The crimping portion 5537 rotates relative to the main body 5531, thereby reducing the friction force on the crimping portion 5537. This can not only protect the crimping portion 5537, but also reduce the resistance encountered by the worm 551 during rotation. Accordingly, the force controlling the rotation of the worm will also be reduced, making it easier to control.

[0025] The worm wheel 553 also includes a limiting portion 5539, which is a protruding structure arranged on the side of the main body 5531. The toothed portion 5533, the crimping portion 5537 and the limiting portion 5539 are arranged at intervals from each other. The limiting portion 5539 cooperates with the mounting seat 53 to limit the position of the transmission between the worm 551 and the worm wheel 553. The installation position of the limiting portion 5539 is associated with the position of the toothed portion 5533 and the crimping portion 5538. Continuing with the working principle of the drone solid-state battery pressurized charger 100, further explanation is given:

[0026] During the pressure relief stage, the meshing position of the worm 551 and the worm wheel 553 is slowly restored to the initial position until the crimping portion 5537 is no longer subjected to force, and the drone solid-state battery 200 is taken out. At this time, the limiting portion 5539 is in contact with the mounting seat 53. The limiting portion 5539 is provided to effectively limit the worm wheel 553 from continuing to rotate, and to prevent the worm 551 from driving the worm wheel 553 to continue to rotate, causing the meshing portion to disengage from the worm 551, protecting the overall structure so that it can continue to be used, and increasing the overall stability and reliability of the transmission assembly 55.

[0027] In order to further ensure that the thickness of the drone solid-state battery 200 does not change during the charging process, in the present embodiment, the transmission assembly 55 is further provided with a partition 557 and a slide bar 559. The partition 557 is arranged in the second accommodating space 503 and is located between the worm gear 553 and the drone solid-state battery 200. The slide bar 559 passes through the mounting seat 53 and the battery rack 51 and is connected to the partition 557. The worm gear 551 controls the rotation of the worm gear 553, thereby pushing the partition 557 to move relative to the battery rack 51.

[0028] The partition 557 is arranged together with the drone solid-state battery 200 in the second accommodation space 503. During the pressing stage, the worm gear 553 pushes the partition 557 to abut against the drone solid-state battery 200, and cooperates with the three side surfaces 11 of the battery rack 51 to limit the position of the drone solid-state battery 200. During the pressure relief stage, the slide bar 559 drives the partition 557 to return to its initial position. The setting of the partition 557 can ensure full contact with the drone solid-state battery 200, ensuring that any position on the drone solid-state battery 200 is subjected to pressure, and there will be no local increase in thickness.

[0029] In order to restore the partition 557 to its initial position, a spring device can be added to the slide bar 559. When the partition 557 is under pressure, the slide bar 559 slides downward to squeeze the spring device; when the partition 557 is not under pressure, the slide bar 559 is acted upon by the elastic force of the spring device, driving the partition 557 to return to its initial position. It should be noted that the slide bar 559 and the partition 557 can also be restored to their initial positions by other means, such as electrically or manually controlling the slide bar 559, or setting a connection on the worm gear 553, the connection is elastically connected to the partition 557, and the rotation of the worm gear 553 drives the position change of the connection, thereby pulling the partition 557 back to its initial position, and no further restrictions are made here. By setting the slide bar 559 to cooperate with the partition, the position of the partition 557 can be prevented from deviation during movement, and each installation can completely abut against the drone fixed battery 200, with good positioning effect, and convenient and labor-saving recovery.

[0030] In this embodiment, the transmission assembly 55 further includes a reinforcing rib 559, which is parallel to the worm 551 and spaced apart from the mounting seat 53. In order to facilitate the layout of the worm 551 and the worm wheel 553, the mounting seat 53 is provided with a first mounting portion 505 on both sides, and the worm 551 is arranged between the first mounting portions 505. As the worm 551 drives the worm wheel 553 to rotate, the first mounting portion 505 is subjected to a force in a direction parallel to the worm 551 in addition to the torsion force, especially in the pressing stage, the force will gradually increase. Repeated use can easily cause damage to the first mounting portion 505, so that the mounting seat 53 needs to be replaced, which is costly. The reinforcing rib 559 is installed at the position where the first mounting portion 505 is parallel to the worm 551, which can effectively fix the position of the first mounting portion 505 on both sides, and it is not easy for them to get close to or away from each other, and the parallel forces are balanced to a certain extent, thereby protecting the first mounting portion 505, extending the service life of the structure, and saving costs.

[0031] In order to further ensure the charging safety of the drone solid-state battery 200, the storage unit 5 is provided with an electrical connection controller 57, and the electrical connection controller 57 is electrically connected to the circuit board 3 for controlling the charging state of the drone solid-state battery 200.

[0032] In this embodiment, the electrical connection controller 57 includes a first terminal 571 and a second terminal 573. The first terminal 571 is arranged on the mounting base 53, and the second terminal 573 is arranged on the side of the worm gear 553 relative to the first terminal 571. The worm 551 controls the rotation of the worm gear 553, thereby controlling the connection state between the first terminal 571 and the second terminal 573.

[0033] During the clamping stage, the worm gear 553 rotates to the clamping position, driving the second terminal 573 to move toward the first terminal 571 until the first terminal 571 contacts the second terminal 573. At this time, the worm gear 553 has rotated to the preset clamping position. The first terminal 571 and the second terminal 573 cooperate with each other to act as a charging switch. After the two are connected, the current is turned on, and the drone solid-state battery 200 can start charging.

[0034] During the pressure relief stage, the first terminal 571 is separated from the second terminal 573, and the drone solid-state battery 200 cannot be charged.

[0035] This setting method can ensure that charging starts only after the drone solid-state battery 200 has been installed and fixed by the battery rack 51 and the transmission assembly 55, which is safer and more reliable; and the setting of the first terminal 571 and the second terminal 573 reduces the steps of manually controlling the charging switch, realizing automatic switching, which is more convenient.

[0036] In order to control the worm 551, the storage unit 5 further includes a transmission controller 59, which is connected to the worm 551 to control the rotation of the worm 551. The transmission controller 59 can control the rotation of the worm 551 by electric control, such as various existing motors; it can also be set as a manual knob to manually control the rotation of the worm 551. The transmission controller 59 mainly provides the power for the rotation of the worm 551, and no further restrictions are made here.

[0037] In this embodiment, the shell 1 includes a first opening 101 and a second opening 102. The first opening 101 is arranged relative to the battery rack 51. The first accommodating space 501 is connected to the outside through the first opening 101. The drone solid-state battery 200 can be placed in the first accommodating space 501 through the first opening 101; the second opening 102 is arranged relative to the worm 551, and the transmission controller 59 is connected to the worm 551 through the second opening 102, which is convenient for user control.

[0038] The working principle of the drone solid-state battery pressurization charger 100 mainly includes four stages: installation stage, pressing stage, charging stage and pressure relief stage, and cycles with each charging of the drone solid-state battery 200. The four stages only rely on the mutual cooperation of the worm 551 and the worm wheel 553, and effectively utilize the battery rack 51 and the mounting seat 53 to achieve changes. The overall design is simple and ingenious, small in size, easy to control and stable.

[0039] Compared with the prior art, the drone solid-state battery pressurized charger 100 connects the second accommodation space 503 in the mounting seat 53 with the first accommodation space 501 in the battery rack 51 by setting the mounting seat 53 and the transmission assembly 55, and then controls the transmission assembly 55 to partially extend out of the second accommodation space 503 and move toward the first accommodation space 501, thereby pressurizing and fixing the drone solid-state battery 200. This setting scheme can ensure that the drone solid-state battery 200 is subjected to the pressure jointly applied by the battery rack 51 and the transmission assembly 55 during the charging process, effectively limiting the range of activity of lithium ions and avoiding recoverable swelling deformation. After charging is completed, the drone solid-state battery 200 can be installed smoothly without irreversible deformation, which increases the service life of the drone solid-state battery 200; and the energy density of the solid-state battery that maintains the original volume is much higher than that of the solid-state battery after swelling. Using a solid-state battery with high energy density on a drone can extend the flight time.

[0040] The transmission assembly 55 realizes force transmission by adopting the transmission mode of the worm wheel 553 and the worm 551, converting the rotational torque into a downward pressure force, so that the overall structural layout of the drone solid-state battery pressurized charger 100 is simple and effective, and the space size of the storage unit 5 is saved. Among them, the worm wheel 553 is provided with the main body 5531, the gear part 5533, the rotating shaft 5535, the crimping part 5537 and the limiting part 5539 that cooperate with each other, which not only safely and reliably and effectively transmits the force of the worm 551, effectively limits the rotation state, but also reduces the processing cost of parts as much as possible.

[0041] The partition plate 557 and the slide bar 559 cooperate with the worm gear 553 to apply pressure more evenly to the drone solid-state battery 200; the electrical connection controller 57 cooperates with the worm gear 553 to improve the overall safety of the drone solid-state battery pressurization charger 100, effectively ensuring that the drone solid-state battery 200 will not swell during charging. The worm gear 553 is not only used for force transmission, but also can be used as a switch to protect the safety of the drone solid-state battery pressurization charger 100. It is multi-functional and has a clever structural design. It greatly reduces other unnecessary structures and reduces production costs, which has great economic value.

[0042] At the same time, the drone solid-state battery pressurized charger 100 provided by the present invention makes it unnecessary to add any additional fixed pressurized structure to the drone solid-state battery 200, giving full play to the volume energy density of lithium metal solid-state batteries, and realizing the huge application value of doubling the endurance of existing drones. Based on this, lithium metal solid-state batteries will be widely used in drones, successfully combining the two in a benign way, realizing the rapid popularization of lithium metal solid-state batteries in the drone industry, promoting the upgrading of the drone industry, and enabling drones to be used in more fields on the basis of comprehensively improving the endurance of drones.

[0043] The above description is only an implementation mode of the present invention. It should be pointed out that, for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present invention, but these all belong to the protection scope of the present invention.
