[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0047] This application proposes a battery pack structure. Figures 1 to 5 These are some embodiments of this application. As shown in the accompanying drawings, the X direction is the first direction, and the Y direction is the second direction. The angle between the first direction X and the second direction Y is not limited and can be 80°, 85°, 90°, etc.

[0048] Please see Figures 1 to 3 In some embodiments of this application, the battery pack structure includes a plurality of battery packs 1, which are arranged along a first direction X. Each battery pack 1 includes at least one battery 11 and two connectors 12. At least a portion of the two connectors 12 is respectively disposed on both sides of the battery 11 in the first direction X and electrically connected to the battery 11. In any two battery packs 1, the two connectors 12 located in different battery packs 1 are connected to each other.

[0049] In the technical solution of this application, multiple battery packs 1 are combined to form a battery pack structure. Since each battery pack 1 includes at least one battery 11 and two connectors 12, the two battery packs 1 can be electrically connected or disconnected by connecting the two connectors 12 in different battery packs 1. That is, the battery pack structure can select all battery packs 1 to supply power or some battery packs 1 to supply power.

[0050] When the battery pack structure is applied to an underwater vehicle, it enables the underwater vehicle to select all or part of the battery packs to power it when the underwater vehicle is in different operating conditions, thus enabling the underwater vehicle to adapt to various underwater operating environments.

[0051] Of course, the battery pack structure in the above embodiments is not limited to underwater vehicles. Other electrical devices that can use electrical energy as an output are also applicable to the battery pack structure in this embodiment, such as aircraft and vehicles.

[0052] The way the two connectors 12 are connected to each other is not limited. They can be directly connected or connected through wires or connectors.

[0053] The above statement that two connectors 12 located in different battery packs 1 are connected to each other means that in the battery pack structure, two adjacent battery packs 1 can be connected to each other; or two battery packs 1 that are spaced apart can be connected to each other, such as three battery packs 1 arranged in sequence along the first direction X, with the two battery packs 1 located on both sides of the middle battery pack 1 connected to each other.

[0054] It should be noted that the multiple battery packs 1 in the battery pack structure can be connected in series or in parallel; there is no restriction here.

[0055] In some embodiments of this application, the connector 12 and the battery 11 can be connected by welding, and the weld points need to be passivated by means of heat shrink tubing, structural adhesive, etc.

[0056] In some embodiments of this application, the connector 12 is made of a flexible conductive material.

[0057] In some embodiments of this application, the connector 12 includes a busbar, that is, the busbar can be electrically connected to the battery.

[0058] The following describes some of the operating conditions of the underwater vehicle:

[0059] If the underwater vehicle is in low-power mode, it can be powered by a single battery pack 1.

[0060] If the underwater vehicle is in a high-power mode, it can use all battery packs 1 for power supply.

[0061] If the underwater vehicle is in a deep-water, high-pressure environment, it can disconnect part of the battery pack 1 in the battery pack structure, thereby reducing the heat generated by the battery pack structure.

[0062] Furthermore, if a portion of the battery pack 1 is damaged, the damaged battery pack 1 can be disconnected, allowing only the normal battery pack 1 to be connected to each other.

[0063] In some embodiments of this application, the number of batteries 11 in each battery pack 1 is set to multiple; each battery pack 1 also includes at least one first fixing member 13, and multiple batteries 11 are fixedly disposed on the first fixing member 13; in this embodiment, by fixing multiple batteries 11 in the battery pack 1 to the first fixing member 13, the stability of the battery pack structure is ensured, and it is also convenient for operators to assemble multiple battery packs 1.

[0064] A battery pack 1 includes multiple batteries 11, which can also increase the energy density of the battery pack structure to enhance the endurance of the underwater vehicle.

[0065] The direction of extension of the multiple batteries 11 is not limited; they can extend in the first direction X or in the second direction Y.

[0066] In some embodiments of this application, the first fixing member 13 is provided with a plurality of limiting holes 2; wherein a portion of the battery 11 is received in the corresponding limiting hole 2; in this embodiment, the number of limiting holes 2 corresponds one-to-one with the number of batteries 11. By assembling a portion of the battery 11 into the limiting hole 2, a plurality of batteries 11 are fixedly disposed on the first fixing member 13 to ensure the stability of the battery pack structure, and also to facilitate the operator to assemble a plurality of battery packs 1.

[0067] In some embodiments, two first fixing members 13 are provided and spaced apart in the first direction X. The limiting holes 2 provided in different first fixing members 13 are correspondingly provided in the first direction X. The battery 11 extends along the first direction X, and the two ends of the battery 11 in the first direction X are respectively received in the limiting holes 2 of the two first fixing members 13. In this embodiment, the two ends of the battery 11 are respectively received in the limiting holes 2 of the two first fixing members 13, that is, the two first fixing members 13 provide two fixing points for the battery 11, ensuring that the battery 11 is securely fixed in the battery pack 1.

[0068] The two first fixing members 13 are located on both sides of the multiple batteries 11 in the first direction X, and can also play a certain protective role for the batteries 11.

[0069] In some embodiments of this application, the two first fixing members 13 are fixed relative to each other so that the battery 11 and the two first fixing members 13 are both fixed, thereby ensuring the stability of the battery pack structure.

[0070] In some embodiments of this application, the two first fixing members 13 are fixed by a plurality of fixing rods 9; wherein the plurality of fixing rods 9 pass through the two first fixing members 13 in the first direction X and are bolted to the first fixing members 13 to ensure that the two first fixing members 13 do not move relative to each other.

[0071] In some embodiments of this application, multiple fixing rods 9 are located around multiple batteries 11. That is, when assembling the battery pack 1, multiple batteries 11 can be assembled between two first fixing members 13 firstly, and then the two first fixing members 13 can be fixed by fixing rods 9. The setting position of the batteries 11 will not interfere with the fixing rods 9, so as to facilitate the assembly of the battery pack 1.

[0072] In some embodiments of this application, the limiting hole 2 extends from one side of the first fixing member 13 in the first direction X into the interior of the first fixing member 13 for the battery 11 to be installed; of course, the limiting hole 2 can be a blind hole or a through hole, which is not limited here.

[0073] It is understandable that when the limiting hole 2 is a blind hole, since the two ends of the battery 11 in the first direction X are the output ends of the battery 11, the connector 12 can be set inside the first fixing member 13, thereby ensuring the normal connection between the connector 12 and the battery 11.

[0074] In some embodiments of this application, at least a portion of the connector 12 is located on the side of the first fixing member 13 away from another first fixing member 13 in the first direction X, and a plurality of batteries 11 pass through the limiting holes 2 and are connected to the connector 12; in this embodiment, since the part of the connector 12 connected to the battery 11 is located outside the first fixing member 13, by setting the output ends of the plurality of batteries 11 to pass through the limiting holes 2, it is ensured that the connector 12 can be normally connected to the battery 11.

[0075] In this embodiment, the limiting hole 2 is a through hole, that is, the output end of the battery 11 will pass through the limiting hole 2 and connect with the connector 12.

[0076] In some embodiments of this application, since the two ends of the multiple batteries 11 are respectively connected to two connectors 12 in the first direction X, the multiple batteries 11 located in the same battery pack 1 are connected in parallel to each other.

[0077] In some embodiments of this application, the connector 12 is fixedly disposed on the first fixing member 13 and electrically connected to a plurality of batteries 11; that is, in this embodiment, the connector 12 is assembled to the first fixing member 13 so that the overall structure of the battery pack 1 is compact and has a higher degree of integration, thereby improving the energy density of the battery pack structure.

[0078] Since the first fastener 13 serves as a fixed limit, the first fastener 13 has high strength, and the connection 12 assembled to the first fastener 13 can also prevent the connection 12 from bending and breaking under external force.

[0079] In some embodiments of this application, the connector 12 includes a first sub-part 121 and a second sub-part 122. The first sub-part 121 is fixedly disposed on one side of the first fixing member 13 in the first direction X and is electrically connected to a plurality of batteries 11. The second sub-part 122 is connected to the first sub-part 121 and extends along the first direction X. At least a portion of the orthographic projection of the second sub-part 122 in the second direction Y falls on the battery 11. In two adjacent battery packs 1, the two second sub-parts 122 located in different battery packs 1 are connected to each other. This arrangement ensures that the connecting component between the two battery packs 1, i.e., the second sub-part 122, does not occupy the space of the battery pack structure in the first direction X, thereby reducing the size of the battery pack structure in the first direction X.

[0080] The second sub-part 122 is located on one side of the battery 11 in the second direction, that is, the second sub-part 122 is located on the outside of the battery 11 and is not blocked by the battery 11, which makes it easier for the operator to connect the two second sub-parts 122.

[0081] In some embodiments of this application, the first fixing member 13 is provided with a receiving groove 3 and a connecting groove 4; wherein, the receiving groove 3 and the connecting groove 4 are connected, and at least a portion of the second sub-part 122 is located in the receiving groove 3 and connected to another second sub-part 122 through the connecting groove 4; such a configuration allows the second sub-part 122 to be protected by the first fixing member 13, preventing excessive exposure of the second sub-part 122 to the external environment, thereby causing damage to the second sub-part 122, and also preventing external conductive structures from directly contacting the second sub-part 122, which could cause the battery pack 1 to short-circuit or pose a risk of electric shock.

[0082] In some embodiments of this application, the receiving groove 3 extends from one side of the first fixing member 13 in the first direction X toward the interior of the first fixing member 13, and the connecting groove 4 extends from one side of the first fixing member 13 in the second direction Y toward one side of the first fixing member 13; wherein, the extending direction of the receiving groove 3 is the same as the extending direction of the second sub-part 122, thereby facilitating the assembly of the second sub-part 122 into the receiving groove 3, and the provision of the connecting groove 4 facilitates the operator to connect the second sub-part 122 in the second direction Y.

[0083] In some embodiments of this application, the battery pack 1 further includes at least one first insulating member 14, which is fixedly disposed on the side of the first sub-part 121 away from the first fixing member 13 in the first direction X. This arrangement ensures that the side of the first sub-part 121 away from the battery 11 is not exposed to the external environment, so as to avoid damage to the first sub-part 121. At the same time, it can also prevent external conductive structures from directly contacting the first sub-part 121, which could cause the battery pack 1 to short circuit or pose a risk of electric shock.

[0084] Furthermore, the provision of the first insulating member 14 also enables two adjacent first sub-parts 121 in two adjacent battery packs 1 to not directly contact each other, so that the operator can disconnect the electrical connection between the two adjacent battery packs 1 or make the electrical connection between the two adjacent battery packs 1 possible.

[0085] Each battery pack 1 is equipped with a first insulating component 14, making the structure of each battery pack 1 identical. The battery pack structure can be formed by modularly assembling the battery pack 1, which facilitates the production and processing of the battery pack structure.

[0086] In some embodiments of this application, the battery pack structure further includes at least one second insulating member disposed between two adjacent battery packs 1 to space two adjacent first sub-parts 121; this arrangement ensures that two adjacent first sub-parts 121 in two adjacent battery packs 1 do not directly contact each other, so that the operator can disconnect the electrical connection between the two adjacent battery packs 1 or make the electrical connection between the two adjacent battery packs 1 stand.

[0087] In this embodiment, a second insulating element is assembled in two adjacent battery packs 1 to form a battery pack structure.

[0088] In some embodiments of this application, the first fixing member 13 is provided with an opening 5, which penetrates the first fixing member 13 in the first direction X and is used to accommodate the guide rail; wherein, the orthographic projection of the battery 11 in the first direction X falls outside the opening 5; this arrangement avoids interference between the battery 11 and the guide rail, and by providing the opening 5, the battery pack structure can move along the guide rail, thereby allowing the battery pack to move to change according to the center of gravity of the underwater vehicle, thereby adapting to the operating conditions of the underwater vehicle at different depths.

[0089] In some embodiments of this application, the battery pack structure further includes at least one bushing 6, at least a portion of which has an opening 5, and the bushing 6 is used to engage with a guide rail; by providing the bushing 6 to engage with the guide rail, the battery pack can be moved to change according to the center of gravity of the underwater vehicle, thereby adapting to the operating conditions of the underwater vehicle at different depths.

[0090] In some embodiments of this application, the bushing 6 is hollow, thereby enabling it to be fitted and installed with the guide rail.

[0091] In some embodiments of this application, both first fixing members 13 located on both sides of the battery pack structure in the first direction X are provided with bushings 6; that is, the bushings 6 can be assembled from the outside of the battery pack structure to the first fixing members 13, so as to facilitate the assembly of the bushings 6 by the operator.

[0092] Please see Figure 4 and Figure 5 In some embodiments of this application, the battery pack structure further includes at least one second fixing member 7, which is fixedly connected to multiple battery packs 1 so that the multiple battery packs 1 are relatively fixed; by providing the second fixing member 7, it is ensured that the multiple battery packs 1 are securely fixed together.

[0093] In some embodiments of this application, the second fixing member 7 includes a pull rod, and each first fixing member 13 is provided with a hole for the pull rod to pass through. The pull rod passes through the hole on each first fixing member 13 and is fastened by bolts, thereby ensuring that the multiple battery packs 1 are securely fixed together.

[0094] In some embodiments of this application, the battery pack structure further includes at least one third fixing member 8, which is fixedly connected to multiple battery packs 1 so that the multiple battery packs 1 are relatively fixed; by providing the third fixing member 8, it is ensured that the multiple battery packs 1 are securely fixed together.

[0095] In some embodiments of this application, the third fixing member 8 includes a pull bar, and a positioning groove is provided on the periphery of each first fixing member 13. The pull bar is disposed in the positioning groove and is connected to multiple first fixing members 13 by bolts, thereby ensuring that multiple battery packs 1 are securely fixed together.

[0096] In some embodiments of this application, each battery pack 1 is further provided with a mounting slot 10. When multiple battery packs 1 are assembled, the mounting slots 10 in the multiple battery packs 1 are interconnected to form a mounting space. A protection board 15 is installed in the mounting space. The protection board 15 can monitor, manage and protect the charging and discharging process of the battery 11 to prevent the battery 11 from being damaged or dangerous.

[0097] In addition, the installation space can also be used for wiring of the battery pack structure.

[0098] In some embodiments of this application, the first fixing member 13 is also provided with a hole that allows the sampling wire harness to pass through, so as to facilitate the routing of the sampling wire harness in the battery pack structure, and at the same time, to limit the sampling wire harness to a certain extent, so that the routing in the battery pack structure is neat.

[0099] In some embodiments of this application, the battery pack structure in this application embodiment can be charged by solar energy to increase the working time of the underwater vehicle and save energy and be environmentally friendly.
