[0032] The utility model provides an external battery for powering a photographic device, wherein the photographic device is provided with a charging interface. Figure 1-Figure 3 , the external battery includes:

[0033] Housing 100;

[0034] A battery module, the battery module is disposed in the housing 100;

[0035] At least two interface members 120 are provided on the housing 100, and the interface members 120 are electrically connected to the battery module, and each of the interface members 120 is adapted to the charging interface of the photographic device 300, so as to charge the photographic device 300;

[0036] The housing 100 is provided with at least two connection structures 200 , and each connection structure 200 is used to connect a photographing device 300 .

[0037] The photographing device 300 may be a photographing device such as an image display, an image transmission receiver, etc.

[0038] The housing 100 is a structure for carrying the battery module and other internal components, and its size and shape can be set as required. For example, if the capacity requirement of the battery module is high, the volume of the battery module will also increase accordingly, and a larger housing 100 size can be set at this time; if the battery capacity requirement is low, the size of the housing 100 can be reduced accordingly to improve the portability of the external battery. It can be understood that the housing 100 can also be set according to the size of the photographic device 300 to be connected. If the photographic device 300 is large, the size of the housing 100 can be set to be large to achieve a stable connection between the two photographic devices 300; if the photographic device 300 is small, the size of the housing 100 can be set to be small to reduce the occupied space. Further, the housing 100 may include an upper housing 100a and a lower housing 100b, and the upper housing 100a and the lower housing 100b are detachably connected by means of snap connection, threaded connection, magnetic connection, etc., which is convenient for the installation, maintenance and replacement of the battery module.

[0039] A battery module generally consists of one or more battery cells, which are combined in a certain arrangement, connected by wires, welding, etc. and supply electrical energy to the photographic device 300. The battery cells can be cylindrical batteries, hexagonal prism batteries, soft-pack batteries, etc., and the present utility model does not limit this. Moreover, there are various connection methods between the battery module and the photographic device 300. For example, it can be connected to various types of interfaces through wires, or connected by wireless charging. It can be understood that if a rechargeable battery is used in the battery module, a charging interface can be provided on the housing 100 for charging the battery module.

[0040] The connection structure 200 is used as a mechanical structure to physically connect with the photographic device 300 to prevent loosening or disconnection during use. Exemplarily, the connection structure 200 can be a jaw structure, and the photographic device 300 is fixed by the contraction and extension between the jaws; the connection structure 200 can also be a magnetic structure, connecting the photographic device 300 by magnetic force, and can also be a threaded structure, a snap structure, etc. that cooperate with the photographic device 300.

[0041] In this embodiment, an example of connecting two external photographic devices 300 is used for illustration. During use, the user can connect the two photographic devices 300 to a connection structure 200 respectively, fix the photographic devices 300 on the housing 100, and connect to the charging interface of the photographic devices 300 through the interface member 120 to supply power to the photographic devices 300. The interface member 120 can be one or more of a USB interface, a DC interface, or a device-specific interface. And in order to be able to charge two or more photographic devices 300 simultaneously, at least two interface members 120 are provided on the housing 100. The interface members 120 can be distributed at different positions on the housing 100 to facilitate connection in different directions and reduce the probability of wire entanglement; they can also be provided on the same side of the housing 100, and the present utility model does not limit this. It can be understood that in actual use, the present utility model can connect multiple photographic devices 300 or only connect one photographic device 300.

[0042] By providing at least two connection structures 200 on the housing 100, the present utility model enables the user to fix at least two photographic devices 300 together without carrying an additional connection device, and the battery module in the housing 100 can supply power to at least two photographic devices 300 through at least two interface members 120, reducing the number of external batteries that the user needs to carry and improving the convenience of carrying external batteries.

[0043] As Figure 2 shown, in some embodiments, the housing 100 has at least two ends arranged in non-parallel directions, and each of the at least two ends is respectively provided with a connection structure 200.

[0044] The shell 100 is of various types, and usually includes different end faces in different directions. Taking the cylindrical shell 100 as an example, two connection structures 200 can be respectively set at the upper and lower ends of the cylindrical shell 100 to prevent the two photographic devices 300 from interfering with each other, and at the same time facilitate the user to hold the side in the middle. The connection method between the connection structure 200 and the cylindrical shell 100 can be selected according to design requirements, and the utility model does not limit this. For example, the connection structure 200 can be, but not limited to, detachably connected to the cylindrical shell 100 by at least one of screw connection, snap connection or plug connection; for another example, the connection structure 200 can also be, but not limited to, non-detachably connected to the cylindrical shell 100 by welding or bonding, or suitable protrusions or grooves can be constructed at both ends of the cylindrical shell 100 as the connection structure 200 to connect the photographic device 300, and the utility model does not limit this. It is understandable that when the housing 100 is an irregular shape, a tetrahedron, a cuboid or other regular polyhedron, the housing 100 has more end faces, more connection structures 200 can be provided, and more photographic devices 300 can be connected. By providing the connection structures 200 at different ends of the housing 100, the photographic devices 300 can be evenly distributed at different positions, thereby improving the overall stability and balance, reducing the shaking caused by the unstable center of gravity of the device, and improving the user experience.

[0045] Preferably, in the present embodiment, the shell 100 is in the shape of a rectangular parallelepiped, which is convenient for production and processing; there are two connecting structures 200, which are respectively arranged at two opposite ends of the rectangular parallelepiped shell 100. When the shell 100 is placed on a plane, it is not easy to overturn or tilt, which facilitates the connection of the photographic equipment 300.

[0046] like Figure 2 As shown, in some embodiments, the connection structure 200 includes at least two limiting grooves 210 , and the at least two limiting grooves 210 are separately arranged on opposite sides of the housing 100 for being engaged with the buckle 310 of the photographic device 300 .

[0047] At least two limiting grooves 210 are provided on the housing 100 to provide a stable clamping effect, and the number of limiting grooves 210 can be increased according to design requirements to further improve the stability of the connection. The limiting grooves 210 are usually provided on opposite sides of the housing 100, which can provide a symmetrical clamping effect, ensure that the housing 100 and the photographic device 300 can be evenly stressed when connected, and reduce the probability of damage to the limiting grooves 210.

[0048] The shape of the limiting groove 210 can be set according to the clamping method and the structure of the buckle 310 on the photographic device 300. For example, the limiting groove 210 is set to a simple columnar shape, so that the buckle 310 on the photographic device 300 can be clamped with the limiting groove 210 by an interference fit; an annular protrusion can also be constructed in the limiting groove 210, so that the buckle 310 on the photographic device 300 is accommodated in the limiting groove 210 and abuts against the bottom of the annular protrusion, thereby locking the buckle 310. The present invention does not impose any restrictions on this.

[0049] like Figure 4 As shown, in some embodiments, the limiting groove 210 includes a groove body 211 and a limiting portion 212, the groove body 211 is used to accommodate the buckle 310 of the photographic equipment 300, the groove body 211 includes a first groove side wall 211a and a second groove side wall 211b that are relatively arranged, and the limiting portion 212 is arranged on the first groove side wall 211a and extends toward the second groove side wall 211b, and is used to limit the buckle 310 of the photographic equipment 300 accommodated in the groove body 211.

[0050] The position-limiting part 212 is a structure for clamping the buckle 310 of the photographic device 300, and there are many ways to set it. For example, the position-limiting part 212 can be a crossbar suspended in the slot body 211, and the connection between the photographic device 300 and the external battery can be achieved by setting the buckle 310 of the photographic device 300 as a hook-shaped structure and hooking the hook-shaped structure to the crossbar; the position-limiting part 212 can also be a protrusion that is tightly attached to the slot body 211, and the buckle 310 of the photographic device 300 is a clamping claw structure, and when clamped in the slot body 211, one end of the clamping claw structure abuts on the protrusion, thereby locking the photographic device 300.

[0051] Preferably, in this embodiment, the limiting portion 212 is extended from the first groove side wall 211a toward the second groove side wall 211b, and a partial gap is left between the limiting portion 212 and the second groove side wall 211b, so that when installing, the buckle 310 of the photographic device 300 first passes through the gap and extends into the groove body 211, and then the photographic device 300 and the external battery are controlled to move relative to each other, so that the limiting portion 212 can abut against the buckle 310 of the photographic device 300, thereby completing the clamping of the two. The setting of the gap allows the buckle 310 of the photographic device 300 to be more easily accommodated in the limiting groove 210, reducing the damage caused by deformation caused by direct insertion into the limiting groove 210, and extending the service life of the buckle 310 and the limiting groove 210.

[0052] like Figure 4 and Figure 5 As shown, in some embodiments, the second groove side wall 211 b has an inclined guide surface 211 c, and the guide surface 211 c is used to guide the buckle 310 of the photographic device 300 into the groove body 211.

[0053] The inclined design of the guide surface 211c allows the user to install the device without having to precisely align the buckle 310 and the slot 211. The user only needs to roughly align the buckle 310 so that it contacts the guide surface 211c. The buckle 310 will then automatically slide into the slot 211 along the guide surface 211c, thereby making the connection between the buckle 310 of the photographic device 300 and the limit slot 210 easier, reducing the possibility of repeated adjustments or damage due to misalignment, and improving the user experience.

[0054] The inclination angle of the guide surface 211c can be set according to actual needs. In this embodiment, the inclination angle of the guide surface 211c is between 30° and 60°, which can ensure that the buckle 310 can slide smoothly into the groove body 211, and will not make the guide surface 211c too flat, thereby occupying too much space and affecting the connection effect between the photographic device 300 and the external battery. Preferably, the connection between the guide surface 211c and the side of the housing 100 is chamfered, so that the buckle 310 can slide into the limiting groove 210 more easily, while reducing the damage caused by the collision between the buckle 310 of the photographic device 300 and the limiting groove 210.

[0055] like Figure 2 and Figure 5 As shown, in some embodiments, at least two positioning grooves 110 are disposed on the housing 100 , and the positioning grooves 110 are respectively disposed at different ends of the housing 100 , and each positioning groove 110 is used for a positioning pin of a photographic device 300 to be inserted.

[0056] During actual use, since the buckle 310 of the photographic device 300 is usually inserted into the limiting groove 210 on the shell 100 in a direction perpendicular to the side of the shell 100 and is snapped into place with the limiting groove 210, the shell 100 and the photographic device 300 are prone to sliding in a direction parallel to the side of the shell 100. Therefore, a positioning groove 110 is provided on the shell 100, which is plugged into the positioning pin on the photographic device 300 to further limit the shell 100 and the photographic device 300, thereby improving the locking effect of the limiting groove 210.

[0057] The shape of the positioning groove 110 is set according to the shape of the positioning pin on the photographic device 300, and is usually round, square or other shapes that are suitable for the positioning pin to ensure that the positioning pin can be accurately inserted and fixed; the size of the positioning groove 110 is slightly larger than the size of the positioning pin, so that the positioning pin can be smoothly inserted and will not be too loose, ensuring the firmness of the fixation. Preferably, the positioning groove 110 is set to a square shape, which can not only prevent the photographic device 300 from rotating during use, but also disperse and absorb part of the stress caused by external forces, reduce direct friction and wear between the photographic device 300 and the housing 100, and extend the service life.

[0058] like Figure 2 and Figure 6 As shown, in some embodiments, each of the at least two ends is also provided with an interface component 120, which is used for: when the connecting structure 200 is connected to the photographic device 300, the interface component 120 is electrically connected to the photographic device 300.

[0059] Exemplarily, the interface component 120 can be a contact. In this case, each end of the external battery includes a connecting structure 200 and a contact. When the connecting structure fixes the photographic device 300, the charging interface of the photographic device 300 is also electrically connected to the contact. There is no need to use wires. The power module can directly supply power to the photographic device 300, thereby reducing the operating steps and improving the user experience.

[0060] like Figure 6 As shown, in some embodiments, the housing 100 includes a connecting surface 130 , and at least two interface members 120 are disposed on the connecting surface 130 .

[0061] The interface components 120 are all arranged on the connection surface 130, which simplifies the design and manufacturing process of the housing 100, reduces mold and processing costs, and improves production efficiency. In addition, by concentrating the interface components 120 on one surface, the other surfaces of the device can be kept simple and beautiful, thereby enhancing the user's visual experience of the product. Furthermore, if the interface components 120 are directly connected to the photographic device 300 by plugging, the interface components 120 are all arranged on the connection surface 130, so that when connecting the photographic device 300, the user only needs to control the external battery to move in the same direction to simultaneously plug in multiple photographic devices 300, thereby realizing power supply to multiple photographic devices 300 and reducing the user's operating difficulty.

[0062] like Figure 6 As shown, in some embodiments, each interface member 120 includes two sockets 121 , the connecting surface 130 is provided with a plurality of mounting grooves 131 , and each socket 121 is disposed in one mounting groove 131 .

[0063] The sockets 121 are respectively arranged in independent mounting grooves 131 to provide better electrical isolation, reduce electrical interference and short circuit risks between the sockets 121, and improve the safety of the device. In addition, the mounting groove 131 has a certain guiding function. When connected with the photographic device 300, the charging interface on the photographic device 300, that is, the plug 320, first enters the mounting groove 131 and then extends into the socket 121, so that the external battery and the photographic device 300 can be more conveniently electrically connected.

[0064] like Figure 2 and Figure 5As shown, in some embodiments, each jack 121 is provided with a polarity mark 140 indicating its polarity.

[0065] The polarity mark 140 allows the user to quickly identify the positive and negative poles when connecting the photographic device 300, helping the user to correctly connect the plug 320 of the photographic device 300, preventing the photographic device 300 from being damaged or malfunctioning due to reverse polarity connection, thereby reducing user errors during connection and improving the user experience.

[0066] Specifically, the polarity mark 140 can be a common positive pole symbol and a negative pole symbol, or can be an arrow or other graphic symbol of a different color, or can be a groove or protrusion of a specific shape, etc., and the present invention does not limit this.

[0067] The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
