Description

Technical Field

[0001] This utility model relates to unmanned aerial vehicles (UAVs), and more specifically, to a UAV battery pack. Background Technology

[0002] Currently, most drone batteries are high-rate pouch batteries. Due to the relatively low power of drone motors and the small size of the drones themselves, the battery pack design is not very sophisticated. It simply uses epoxy board or heat-shrink film, along with foam and masking tape, to bind and secure the battery modules, along with a custom-molded plastic casing. This completes the production of the drone battery pack. However, existing drone battery packs have the following problems:

[0003] 1. The cost of mold making and auxiliary materials is too high, but the selling price of drone batteries is too low, resulting in a long investment payback period;

[0004] 2. Because the battery module is made of stacked soft-pack battery packs wrapped with epoxy board or heat shrink film and finally encapsulated in a molded plastic shell, the heat of the battery module cannot be effectively dissipated during high-rate use, resulting in a short battery pack life.

[0005] 3. Because epoxy boards and other auxiliary materials are used in the production process of the battery pack, the weight of the battery pack may be overloaded, which will affect the drone's flight time.

[0006] 4. Because the battery pack is made of epoxy board or heat shrink film with foam and masking tape for binding and fixing, and then fitted with a plastic shell, it is relatively large in size. However, the drone itself is small, resulting in the battery pack accounting for a large proportion of the total volume.

[0007] Clearly, existing drone battery packs suffer from drawbacks such as large size and poor heat dissipation. Utility Model Content

[0008] To address the technical problems of large size and poor heat dissipation performance of existing drone battery packs, this invention provides a drone battery pack and a drone.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is to design a drone battery pack, including a battery module and wiring provided on the battery module. The drone battery pack also includes an outer sheath covering the battery module. The outer sheath is integrally formed by thermally conductive structural adhesive, and multiple rows of outwardly protruding and spaced heat dissipation teeth are integrally formed on the outer surface of the outer sheath. The wiring extends out of the outer sheath.

[0010] The outer layer is integrally formed by covering the battery module with a mold and then pouring the thermally conductive structural adhesive.

[0011] The heat dissipation teeth are located on the side of the outer cladding.

[0012] The heat dissipation denticles are evenly spaced on the four sides of the outer cladding.

[0013] The heat dissipation teeth are distributed on all four sides of the outer cladding.

[0014] The heat dissipation teeth are arranged vertically from top to bottom, and a vertical heat dissipation gap is formed between adjacent heat dissipation teeth.

[0015] The battery module includes a pouch battery pack, an adapter plate disposed above the pouch battery pack, and a protection plate disposed above the adapter plate; the wiring is electrically connected to the adapter plate, and the adapter plate is electrically connected to the pouch battery pack.

[0016] The wiring includes power cables and data cables.

[0017] The thermally conductive structural adhesive is a two-component polyurethane thermally conductive structural adhesive.

[0018] This utility model also provides a drone having the aforementioned drone battery pack.

[0019] This invention features a battery module and wiring attached to it, along with an outer sheath covering the battery module. This outer sheath is integrally molded from thermally conductive structural adhesive, and its outer surface is integrally formed with multiple rows of outwardly protruding, spaced-apart heat dissipation teeth. The wiring extends beyond the outer sheath. Therefore, only the outer sheath made of thermally conductive structural adhesive is needed to cover the battery module; there is no need for epoxy board or heat-shrink film with foam and masking tape for binding and fixing, nor for a separate plastic shell. Compared to existing drone battery packs, this design is smaller. Furthermore, the thermally conductive structural adhesive tightly encapsulates the battery module, effectively securing it and dissipating heat through the adhesive's excellent thermal conductivity. The heat is then quickly dissipated through the heat dissipation teeth on the adhesive's outer surface. Additionally, the wind generated during drone flight further helps to remove battery heat more rapidly by blowing on the heat dissipation teeth. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the embodiments and accompanying drawings, wherein:

[0021] Figure 1 This is a structural diagram of the unmanned aerial vehicle (UAV) battery pack of this utility model;

[0024] The specific embodiments of this utility model are further described below with reference to the accompanying drawings:

[0025] Please see also Figures 1 to 3 The UAV battery pack of this utility model includes a battery module 1, wiring 2, and an outer sheath 3.

[0026] in:

[0027] The battery module 1 includes a pouch battery pack 11, an adapter plate 12 disposed above the pouch battery pack, and a protection plate 13 disposed above the adapter plate; the wiring is electrically connected to the adapter plate, and the adapter plate is electrically connected to the pouch battery pack. The battery module is the core component of the battery pack, used to provide energy storage and output. The pouch battery pack consists of multiple cells arranged side-by-side. The adapter plate connects the cells, linking them to external electronic modules via wiring. The protection plate protects the cells and the adapter plate.

[0028] Wiring 2 is located on the battery module and serves for electrical conduction and signal transmission. The wiring extends beyond the outer sheath to connect to external electronic modules. The wiring includes power lines and data lines.

[0029] The outer sheath 3 covers the battery module. The outer sheath is integrally molded from thermally conductive structural adhesive, and multiple rows of outwardly protruding, spaced-apart heat dissipation teeth 31 are integrally formed on the outer surface of the outer sheath. Because the thermally conductive structural adhesive has good thermal conductivity, it can promptly conduct heat generated by the battery module, and dissipate the heat through the heat dissipation teeth on the outer surface. Existing thermally conductive structural adhesives can be used; it only needs to be able to harden into an outer sheath. In this specific embodiment, the thermally conductive structural adhesive is a two-component polyurethane thermally conductive structural adhesive.

[0030] This invention features a battery module and wiring attached to it, along with an outer sheath covering the battery module. This outer sheath is integrally molded from thermally conductive structural adhesive, and its outer surface is integrally formed with multiple rows of outwardly protruding, spaced-apart heat dissipation teeth. The wiring extends beyond the outer sheath. Therefore, only the outer sheath made of thermally conductive structural adhesive is needed to cover the battery module; there is no need for epoxy board or heat-shrink film with foam and masking tape for binding and fixing, nor for a separate plastic shell. Compared to existing drone battery packs, this design is smaller. Furthermore, the thermally conductive structural adhesive tightly encapsulates the battery module, effectively securing it and dissipating heat through the adhesive's excellent thermal conductivity. The heat is then quickly dissipated through the heat dissipation teeth on the adhesive's outer surface. Additionally, the wind generated during drone flight further helps to remove battery heat more rapidly by blowing on the heat dissipation teeth.

[0031] In this specific embodiment, the outer sheath 3 is integrally formed by casting the thermally conductive structural adhesive after the battery module is encased in a mold. That is, during the manufacturing process, the battery module is placed in the mold, the thermally conductive structural adhesive is poured into the mold, and the wiring extends out of the adhesive. After the adhesive hardens, the mold is removed, thus completing the fabrication of the outer sheath. The finished outer sheath not only tightly encapsulates the battery module, providing excellent thermal conductivity and waterproofing, but also exhibits excellent heat dissipation due to the formation of multiple rows of heat dissipation fins on its outer surface.

[0032] In this specific embodiment, the heat dissipation teeth 31 are disposed on the side surface of the outer cladding layer. Preferably, the heat dissipation teeth are evenly spaced on the four side surfaces of the outer cladding layer. Having heat dissipation teeth on all four side surfaces allows for better heat dissipation.

[0033] In this specific embodiment, the heat dissipation denticles 31 are distributed across all four sides of the outer cladding. By increasing the distribution area of ​​the heat dissipation denticles, the heat dissipation effect can be better enhanced.

[0034] In this specific embodiment, the heat dissipation teeth 31 are arranged vertically from top to bottom, and a vertical heat dissipation gap 311 is formed between adjacent heat dissipation teeth. The vertical arrangement of the heat dissipation teeth facilitates manufacturing and also makes it easier to match the airflow direction during drone flight, resulting in better heat dissipation.

[0035] The present invention relates to a drone battery pack that can be used in drones, wherein the drone has the aforementioned drone battery pack.

[0036] This invention features a battery module and wiring attached to it, along with an outer sheath covering the battery module. This outer sheath is integrally molded from thermally conductive structural adhesive, and its outer surface is integrally formed with multiple rows of outwardly protruding, spaced-apart heat dissipation teeth. The wiring extends beyond the outer sheath. Therefore, only the outer sheath made of thermally conductive structural adhesive is needed to cover the battery module; there is no need for epoxy board or heat-shrink film with foam and masking tape for binding and fixing, nor for a separate plastic shell. Compared to existing drone battery packs, this design is smaller. Furthermore, the thermally conductive structural adhesive tightly encapsulates the battery module, effectively securing it and dissipating heat through the adhesive's excellent thermal conductivity. The heat is then quickly dissipated through the heat dissipation teeth on the adhesive's outer surface. Additionally, the wind generated during drone flight further helps to remove battery heat more rapidly by blowing on the heat dissipation teeth.

[0037] This invention can be widely applied to drones and has the following characteristics:

[0038] 1. This utility model's drone battery pack uses a thermally conductive structural adhesive commonly used in new energy power storage to create the outer sheath. After the thermally conductive structural adhesive solidifies, it forms the outer sheath, and multiple rows of heat dissipation ridges are formed on the outer surface of the outer sheath. This not only provides good thermal conductivity but also better heat dissipation. Simultaneously, during drone flight, wind is generated on the surface, blowing through the heat dissipation ridges, which can more quickly dissipate heat from the battery.

[0039] 2. The cost of thermally conductive structural adhesive is low, and the cost per battery pack is far less than the mold opening cost and auxiliary material cost of existing technologies.

[0040] 3. Compared with traditional drone battery packs, the drone battery pack of this utility model only uses thermally conductive structural adhesive as a material, and does not require plastic molded shell, epoxy board, heat shrink film, foam and other materials.

[0041] 4. This utility model can effectively reduce the volume of the battery pack, reducing the volume by about 9% compared to traditional battery packs.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
