Description

[0001] The present invention relates to the field of battery technology, in particular to a semi-solid battery device for a cargo-carrying unmanned aerial vehicle. Background Art

[0002] Cargo drones have been widely used in logistics distribution, surveying and mapping, agricultural plant protection and other fields. As a key energy component of drones, the performance of batteries directly affects the endurance, load-bearing capacity and flight safety of drones.

[0003] The semi-solid-state battery of the cargo drone is relatively small in size, and the battery of the cargo drone is composed of a whole battery pack with a complex internal structure. Once the internal electrodes, diaphragms and other components are damaged due to external impact, manufacturing defects and other reasons, it is more likely to cause an internal short circuit. And because it is a whole, the harm caused by the short circuit will quickly spread to the entire battery pack. If a part of the battery pack fails or is damaged, it is difficult to repair the specific fault point separately because it is a whole structure. Usually, the entire battery pack can only be replaced as a whole, resulting in extremely high maintenance costs. Summary of the invention

A locking bolt is connected to the external thread of the vertical threaded rod.

[0011] Preferably, the number of the structure composed of the pressure plates and the side pressure plates is twice the number of the semi-solid electrolytic bags, so as to ensure that both the upper and lower surfaces of each semi-solid electrolytic bag are under pressure.

[0012] Preferably, the connecting mechanism includes a first assembly plate and a second assembly plate, the first assembly plate and the second assembly plate are respectively installed on the proximal sides of two semi-solid electrolytic packages, and the proximal sides of the first assembly plate and the second assembly plate are adapted in shape.

[0013] Preferably, the first assembly plate and the second assembly plate are both provided with docking seats, the docking seats are provided with connecting components, and the two connecting components are arranged in rotational symmetry, and the connecting components are provided with arc-shaped clamping grooves; An inner fixing column is fixedly mounted on the connecting assembly, a second spring is movably sleeved outside the inner fixing column, a circular clamping column is fixedly mounted on the end of the second spring, and the circular clamping column is movably engaged in the arc-shaped clamping groove.

[0014] Preferably, the circular clamping column is movably sleeved outside the inner fixing column, and the circular clamping column moves along the axial direction of the inner fixing column.

[0015] Preferably, a sealing mechanism is provided at the opening of the semi-solid electrolysis bag, for sealing the connection between the semi-solid electrolysis bag and the electrode rod; The sealing mechanism includes a first sealing ring located on the inner side and a second sealing ring located on the outer side, and the second sealing ring is fixedly connected to the first sealing ring.

Timely replacement of damaged semi-solid electrolytic packs can avoid affecting other normal parts, maintain stable battery performance, and extend the service life of the entire battery.

[0018] 2. When the outer skin of the semi-solid electrolytic package bulges due to special circumstances, the first spring is deformed, and the elastic force generated by the deformation of the first spring is used to push the pressure plate and the side pressure plate to form a structure, thereby transmitting pressure to the semi-solid electrolytic package, flattening the bulging outer skin of the semi-solid electrolytic package, reducing the bulging phenomenon of the semi-solid electrolytic package, and improving the durability of the semi-solid electrolytic package. The bulging of the semi-solid electrolytic package may affect the internal material distribution and ion conduction, resulting in a decrease in battery performance. By flattening the bulge in time, the internal structure can be guaranteed to be uniform, and the battery capacity, charge and discharge efficiency and other performance can be maintained stable.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all 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.

[0034] See also Figures 1 to 13 , the present invention provides a technical solution: a semi-solid battery device for a cargo-carrying drone, comprising a battery assembly shell 1, and a sealing end cover 2 movably mounted at the open end of the battery assembly shell 1 by bolts; The battery assembly shell 1 is a shell structure with a cavity inside and a mounting hole outside. At the same time, a sealing end cover 2 is movably installed on the battery assembly shell 1. The battery assembly shell 1 is provided with mounting holes corresponding to the bolts on the sealing end cover 2 to realize the assembly of the battery assembly shell 1 and the sealing end cover 2. At the same time, a protrusion is provided on the sealing end cover 2 close to the side of the battery assembly shell 1 to assist in the alignment of the sealing end cover 2. At the same time, the design of the protruding part of the sealing end cover 2 can provide stability for the organization of the battery assembly shell 1 and the sealing end cover 2. A group of electrode rods 3 are fixedly mounted on the battery assembly shell 1, and multiple groups of semi-solid electrolytic packs 4 are movably mounted outside the electrode rods 3. The semi-solid electrolytic packs 4 are located inside the battery assembly shell 1. The electrode rods 3 and the semi-solid electrolytic packs 4 form a power supply assembly located inside the battery assembly shell 1. In the internal space of the battery assembly shell 1, a group of electrode rods 3 are firmly fixed therein. The electrode rods 3 bear the key conductive function and are an important component of the entire power supply assembly.

[0035] On the outside of the electrode rod 3, a plurality of groups of semi-solid electrolytic packs 4 are movably installed. These semi-solid electrolytic packs 4 are located inside the battery assembly shell 1. They cooperate closely with the electrode rod 3 to form a power supply component located inside the battery assembly shell 1. When the entire battery device starts working, an electrochemical reaction occurs inside the semi-solid electrolytic pack 4, and the generated electrons are effectively connected to the electrode rod 3 to achieve directed movement, thereby forming an electric current and providing stable power output for external devices.

[0036] Flattening mechanisms 5 are provided above and below the battery assembly shell 1, and the flattening mechanisms 5 are used to apply pressure to the semi-solid electrolytic bag 4 to prevent the semi-solid electrolytic bag 4 from deforming; Flattening mechanisms 5 are provided above and below the battery assembly shell 1. The flattening mechanisms 5 play a vital role in that they can continuously and stably apply pressure to the semi-solid electrolytic package 4. During the use of the semi-solid battery, the semi-solid electrolytic package 4 may bulge, expand, and other deformations due to factors such as charging and discharging and temperature changes. The flattening mechanism 5 effectively avoids this situation. By precisely controlling the pressure, the semi-solid electrolytic package 4 is always kept in a stable state, thereby ensuring the stability and safety of the entire battery system, ensuring that the semi-solid battery can work normally and efficiently, and extending its service life.

[0037] The semi-solid electrolysis bags 4 are connected with each other by a connecting mechanism 6 , and the semi-solid electrolysis bags 4 connected in a split manner are fixed by the connecting mechanism 6 .

[0038] The multiple semi-solid electrolysis packs 4 are not isolated from each other, but are tightly connected through the connecting mechanism 6. This split connection design allows each semi-solid electrolysis pack 4 to remain relatively independent while working in coordination. The connecting mechanism 6 plays a key role. Through the unique structural design, the semi-solid electrolysis packs 4 are firmly fixed together to ensure that during the battery charging and discharging process, the semi-solid electrolysis packs 4 will not be displaced or fall off due to vibration, shaking or other external forces, thereby ensuring the stability and reliability of the entire battery system and allowing the semi-solid battery to stably output electrical energy to meet the power requirements of the equipment.

[0039] The sealing end cover 2 and the battery assembly shell 1 form a sealed cavity, and the battery assembly shell 1 is provided with a mounting hole corresponding to the electrode rod 3 .

[0040] The semi-solid electrolytic packs 4 are disposed on the battery assembly shell 1 in a bilaterally symmetrical manner, and a plurality of groups of semi-solid electrolytic packs 4 are evenly and equidistantly disposed in the battery assembly shell 1 .

[0041] Multiple groups of semi-solid electrolytic packs 4 are evenly arranged at equal distances in the battery assembly shell 1. The evenly spaced distribution ensures that the spacing between each semi-solid electrolytic pack 4 is consistent, which is conducive to even heat dissipation and avoids local overheating that affects battery performance. The even arrangement also balances the pressure on each semi-solid electrolytic pack 4, reducing the risk of deformation or damage caused by uneven force, thereby improving the stability and service life of the entire battery system, allowing the battery to operate stably and efficiently under various working conditions.

[0042] The sealing end cover 2 is provided with a hole corresponding to the end of the electrode rod 3 , and pressure in a corresponding direction is applied to the end of the electrode rod 3 through the sealing end cover 2 .

[0043] A hole corresponding to the end of the electrode rod 3 is pre-opened on the sealing end cover 2. The position and size of the hole are designed to accommodate the end of the electrode rod 3. When the sealing end cover 2 is installed on the battery assembly shell 1, it can not only play a good sealing role to prevent external impurities, moisture, etc. from entering the interior of the battery and affecting the performance, but also apply pressure in the corresponding direction to the end of the electrode rod 3. Through this pressure, the connection between the electrode rod 3 and other components is stabilized, reducing poor contact problems caused by vibration and shaking, ensuring stable current transmission, and ensuring the normal operation of the entire battery system.

[0044] The flattening mechanism 5 includes a pressure plate 501, and side pressure plates 502 are fixedly installed on both sides of the pressure plate 501. The pressure plate 501 and the side pressure plates 502 form a structure supported at corresponding positions on the center of the upper surface of the semi-solid electrolytic package 4, and the pressure plate 501 is movably installed on the battery assembly shell 1; The core component of the flattening mechanism 5 is the pressure plate 501, on both sides of which the side pressure plates 502 are firmly fixed, and the pressure plate 501 and the side pressure plates 502 cooperate with each other to form a stable structure. This structure is precisely supported at the corresponding position of the center of the upper surface of the semi-solid electrolytic bag 4, and can evenly disperse the pressure to ensure the balance of the pressure applied to the semi-solid electrolytic bag 4.

[0045] The battery assembly shell 1 is provided with a mounting hole corresponding to the pressure plate 501 .

[0046] A vertical connecting rod 504 is fixedly installed on the top of the pressure plate 501, and a mounting frame 505 is movably sleeved outside the vertical connecting rod 504. A horizontal connecting plate 503 is provided between the pressure plates 501 for fixed connection; A vertical threaded rod 506 is fixedly installed on the top of the horizontal connecting plate 503, and the vertical threaded rod 506 is movably inserted into the mounting frame 505. A first spring 507 is movably sleeved outside the vertical threaded rod 506. The first spring 507 is located between the mounting frame 505 and the horizontal connecting plate 503. A locking bolt 508 is connected to the external thread of the vertical threaded rod 506.

[0047] By changing the position of the vertical threaded rod 506 on the mounting frame 505, the moving stroke of the structure composed of the pressure plate 501 and the side pressure plate 502 can be changed, and the deformation amplitude of the first spring 507 can be changed to change the distance between the structure composed of the pressure plate 501 and the side pressure plate 502 and the bulging part of the battery panel, thereby controlling the maximum pressure position of the pressure plate 501 and the side pressure plate 502 on the battery panel to prevent the bulging part of the battery panel from being overly pressurized and damaged.

[0048] The transverse connecting plate 503 plays a key connecting role in the structure. The vertical threaded rod 506 is firmly fixed on the top thereof. The vertical threaded rod 506 is installed on the mounting frame 505 in a movable plug-in manner. This connection method allows the vertical threaded rod 506 to move to a certain extent in the mounting frame 505 while maintaining relative stability.

[0049] A movable first spring 507 is sleeved on the outside of the vertical threaded rod 506. The first spring 507 is cleverly located between the mounting frame 505 and the horizontal connecting plate 503. The first spring 507 is elastic. When subjected to external force, it can deform and store elastic potential energy. When the external force disappears, it can return to its original shape and release energy. This characteristic enables the first spring 507 to play a role in buffering and regulating pressure in the entire structure.

[0050] In addition, the outside of the vertical threaded rod 506 is also connected to a locking bolt 508 through a thread. The existence of the locking bolt 508 is very important. By rotating the locking bolt 508, the position of the vertical threaded rod 506 in the mounting frame 505 can be adjusted, and then the compression degree of the first spring 507 can be adjusted. In this way, the pressure applied by the pressure plate 501 to the semi-solid electrolytic bag 4 can be accurately controlled according to actual needs to achieve the best flattening effect, ensure the stability of the semi-solid electrolytic bag 4, and prevent it from deformation.

[0051] The number of the structure composed of the pressure plates 501 and the side pressure plates 502 is twice the number of the semi-solid electrolytic bags 4 to ensure that the upper surface and the lower surface of each semi-solid electrolytic bag 4 are under pressure.

[0052] The connecting mechanism 6 includes a first assembly plate 601 and a second assembly plate 602. The first assembly plate 601 and the second assembly plate 602 are respectively installed on the proximal sides of the two semi-solid electrolytic bags 4. The proximal sides of the first assembly plate 601 and the second assembly plate 602 are adapted in shape.

[0053] The first assembly plate 601 and the second assembly plate 602 are both provided with a docking seat 604, and a connecting component 605 is provided on the docking seat 604. The two connecting components 605 are arranged in rotational symmetry, and an arc-shaped clamping groove 6051 is opened on the connecting component 605; An inner fixing column 606 is fixedly mounted on the connecting component 605 , and a second spring 607 is movably sleeved outside the inner fixing column 606 . A circular clamping column 608 is fixedly mounted on the end of the second spring 607 , and the circular clamping column 608 is movably engaged in the arc-shaped clamping groove 6051 .

[0054] The circular clamping column 608 is movably sleeved outside the inner fixing column 606 , and the circular clamping column 608 moves along the axial direction of the inner fixing column 606 .

[0055] The circular clamping column 608 is movably sleeved outside the inner fixing column 606 and can move axially along the inner fixing column 606. When assembling, under a certain external force, the circular clamping column 608 can overcome the elastic force of the second spring 607 and move axially along the inner fixing column 606, so that the two connecting components 605 can approach each other. When moved to the appropriate position, the second spring 607 recovers the deformation and pushes the circular clamping column 608 to snap into the arc-shaped clamping groove 6051, thereby realizing a firm connection between the first assembly plate 601 and the second assembly plate 602. When disassembly is required, external force is applied again to make the circular clamping column 608 overcome the spring elastic force and disengage from the arc-shaped clamping groove 6051, so that the two assembly plates can be separated. This connection method not only ensures the reliability of the connection, but also facilitates installation and disassembly, plays an important role in the connection and fixation of the semi-solid electrolytic package 4, and ensures the stability and maintainability of the entire battery structure.

[0056] A sealing mechanism 7 is provided at the opening of the semi-solid electrolytic bag 4, for sealing the connection between the semi-solid electrolytic bag 4 and the electrode rod 3; The sealing mechanism 7 includes a first sealing ring 701 located on the inner side and a second sealing ring 702 located on the outer side, and the second sealing ring 702 and the first sealing ring 701 are fixedly connected together, and a reinforcement ring 703 is provided on the side of the second sealing ring 702 away from the first sealing ring 701 for connection, and an annular groove 704 is opened on the outer wall of the second sealing ring 702, and a locking rope 705 is provided in the annular groove 704 for locking.

[0057] The inner first sealing ring 701 and the outer second sealing ring 702 are closely connected to form a multi-layer sealing structure. This double-layer sealing design can more effectively block the entry of external impurities and improve the reliability of the seal. A reinforcement ring 703 is provided on the side of the second sealing ring 702 away from the first sealing ring 701. The presence of the reinforcement ring 703 further enhances the structural strength of the second sealing ring 702, so that it can better maintain its shape when subjected to external force, thereby ensuring the stability of the sealing performance.

[0058] There are two sealing mechanisms 7 on the semi-solid electrolytic bag 4, and the two sealing mechanisms 7 are symmetrically arranged front to back.

[0059] Working principle: Step 1: Align the sealing mechanism 7 on the semi-solid electrolysis bag 4 with the electrode rod 3, flexibly sleeve the semi-solid electrolysis bag 4 outside the electrode rod 3, and then install the next semi-solid electrolysis bag 4 on the electrode rod 3, align the first assembly plate 601 on the semi-solid electrolysis bag 4 with the second assembly plate 602 on another semi-solid electrolysis bag 4, and snap the first assembly plate 601 onto the second assembly plate 602. The two docking seats 604 contact each other, and the connecting components 605 contact each other. When the circular clamping column 608 on the connecting component 605 is subjected to the pressure of the connecting component 605, the circular clamping column 608 moves on the inner fixing column 606 and applies pressure to the second spring 607 until the circular clamping column 608 reaches the arc clamping position. When the battery is in the position of the groove 6051, the circular clamping column 608 subjected to the elastic force of the second spring 607 pops out and engages in the arc-shaped clamping groove 6051 to achieve the docking between the two connecting components 605, to achieve the connection between the first assembly plate 601 and the second assembly plate 602, thereby achieving the connection and fixation between the two adjacent semi-solid electrolysis packs 4, and then the other semi-solid electrolysis packs 4 are installed in the battery assembly shell 1, and then the sealing end cover 2 is installed on the battery assembly shell 1 to achieve the installation and fixation of the semi-solid electrolysis pack 4 in the battery assembly shell 1. After a single semi-solid electrolysis pack 4 is damaged, the operation can be reversed to remove the single damaged semi-solid electrolysis pack 4 to achieve the replacement of the single semi-solid electrolysis pack 4.

[0060] Step 2: As needed, select the locking rope 705 to tighten the second sealing ring 702. The tightened second sealing ring 702 can better wrap around the electrode rod 3 to achieve the installation of the sealing mechanism 7 outside the electrode rod 3. At the same time, the reinforcement ring 703 can also tighten the second sealing ring 702 to reduce the deformation effect of the second sealing ring 702, improve the deformation resistance of the second sealing ring 702, and increase the service life of the second sealing ring 702.

[0061] Step 3: When the outer skin of the semi-solid electrolytic bag 4 bulges due to special circumstances, the bulged part of the outer skin of the semi-solid electrolytic bag 4 applies pressure to the structure composed of the pressure plate 501 and the side pressure plate 502, and the pressure plate 501 and the side pressure plate 502 can be deformed. When the pressure plate 501 and the side pressure plate 502 are under pressure, the pressure is transmitted to the transverse connecting plate 503, and the transverse connecting plate 503 transmits the pressure to the first spring 507, driving the first spring 507 to deform, and the first spring 507 transmits the pressure to the mounting frame 505 fixed on the cargo-carrying drone, and the elastic force generated by the deformation of the first spring 507 is used to push the structure composed of the pressure plate 501 and the side pressure plate 502, and transmit the pressure to the semi-solid electrolytic bag 4, so as to flatten the bulging outer skin of the semi-solid electrolytic bag 4, reduce the bulging phenomenon of the semi-solid electrolytic bag 4, and improve the durability of the semi-solid electrolytic bag 4.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
