[0040] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0041] In electronic devices such as cameras and drones, batteries are typically required to power the devices. To improve battery life, users can use battery holders to charge the batteries. However, battery holders in this technology usually have a top and bottom cover design, resulting in a large overall size, poor portability and aesthetics, and complicated operation when users need to charge them, leading to a poor user experience.

[0042] To address the problems existing in related technologies, this application provides a battery holder with a surface that is flush with or smoothly transitions to the surface of the battery cover. This creates a seamless appearance when the battery body is housed in the battery compartment, improving the aesthetics of the battery holder and reducing the risk of damage to the battery. Furthermore, since the battery has a cover that mates with the battery holder body, there is no need for an additional protective cover to shield the battery. This facilitates a compact and lightweight design for the battery holder, makes it easier to place and remove the battery, and enhances the reliability, convenience, and user experience of the battery holder.

[0043] According to an exemplary embodiment, such as Figures 1-10As shown, this application embodiment provides a battery holder, which includes a battery holder body 10 and a battery compartment 20 disposed on the battery holder body 10. The battery compartment 20 is used to accommodate a battery 30, such as a camera battery, a drone battery, or other battery type that can be charged separately from the electronic device. The battery 30 includes a battery body 301 and a battery cover connected to the battery body 301. When the battery body 301 is accommodated in the battery compartment 20, the battery cover 302 is connected to the battery holder body 10 through a detachable connection structure 31, and the battery cover 302 is flush with or smoothly transitions to the surface of the battery holder body 10. The appearance of the battery holder body 10 and the appearance of the battery 30 complement each other, thereby achieving an integrated appearance of the battery 30 and the battery holder.

[0044] The battery cover 302 is flush with the surface of the battery holder body 10, meaning their surfaces are on the same plane. The smooth transition between the battery cover 302 and the battery holder body 10 means the seam between their surfaces is smoothly connected using methods such as bevel transitions or arc transitions. By making the battery cover 302 flush with or smoothly transitioning with the battery holder body 10, the seam is inconspicuous and difficult to distinguish, resulting in a sleek, integrated appearance for the battery holder. Furthermore, when the battery 30 is a camera battery, the appearance of the battery holder body 10 can be designed to resemble a camera, and the position of the battery compartment 20 on the battery holder can correspond to the position of the camera's battery compartment on the camera, providing a clear indication of the battery 30's location and improving ease of use.

[0045] In addition, since the surface of the battery 30 smoothly transitions with the surface of the battery holder body 10 when the battery 30 is housed in the battery compartment 20, the battery 30 is not easily damaged by bumps. Therefore, it is not necessary to set a battery protective cover that protrudes from the battery holder body 10. Instead, a battery protective cover can be omitted or set to be flush with or lower than the surface of the battery holder body 10. This helps to make the battery holder design compact and lightweight, and also makes it easier for users to place and take out the battery 30.

[0046] In this embodiment, the battery holder is designed to smoothly transition with the battery surface, thereby forming an integrated appearance when the battery body is housed in the battery compartment, which improves the aesthetics of the battery holder. At the same time, it eliminates the need for an additional battery protective cover protruding from the battery holder body, which helps to make the battery holder design compact and lightweight, and also facilitates the removal and placement of batteries, thereby improving the reliability, convenience, and user experience of the battery holder.

[0047] In some embodiments, the battery holder further includes a first protective cover 21. For example... Figures 8-9As shown, the first protective cover 21 is used to protect the battery compartment 20 when the battery 30 is not placed inside, preventing dust, moisture, and other impurities from entering the battery compartment 20 and affecting its function. The first protective cover 21 is movably connected to the battery holder body 10, such as by rotation or sliding, and the first protective cover 21 can move relative to the battery holder body 10 between a first position and a second position. When the first protective cover 21 is in the first position, it covers the opening of the battery compartment 20, thus providing protection. When the first protective cover 21 is in the second position, it is accommodated inside the battery compartment 20 and / or the battery holder body 10. A protective cover receiving groove 211 can be provided inside the battery compartment 20 and / or the battery holder body 10. When the first protective cover 21 is in the second position, it can be accommodated in the protective cover receiving groove 211, thereby avoiding the battery 30 and ensuring that the first protective cover 21 does not affect the battery 30.

[0048] In one example, the first protective cover 21 is rotatably connected to the battery holder body 10. For example... Figure 8 As shown, the battery holder also includes a rotating member 22. The first protective cover 21 is connected to the battery holder body 10 via the rotating member 22, allowing the first protective cover 21 to move between a first position and a second position. Figure 8 Taking the orientation shown as an example, when the first protective cover 21 is in the first position, the first protective cover 21 along... Figure 8 The horizontally extending arrangement shown in the diagram obstructs the opening of the battery compartment 20 extending vertically; when the first protective cover 21 is in the second position, the first protective cover 21 extends along... Figure 8 As shown, the horizontally extending arrangement includes a first protective cover 21 housed within a protective cover receiving groove 211 inside the battery compartment 20, ensuring that it does not affect... Figure 9 The battery 30 shown is being charged.

[0049] In one example, the battery holder also includes a resilient element 23 to allow the first protective cover 21 to move and return between a first position and a second position. The resilient element 23 has a preload, such as... Figure 8 As shown, in the absence of external force, the preload of the elastic element 23 keeps the first protective cover 21 in the first position, protecting the battery compartment 20; when the user needs to use the battery holder... Figure 9 When the battery 30 shown is being charged, it is placed in the battery compartment 20. The battery 30 exerts a force on the first protective cover 21. Under the action of the external force, the elastic member 23 undergoes elastic deformation, and the first protective cover 21 can move to the second position to avoid affecting the charging of the battery 30. When the battery 30 is removed, the external force disappears, and the elastic deformation of the elastic member 23 is restored, so that the first protective cover 21 is reset to the first position.

[0050] In some embodiments, when the battery 30 is housed within the battery compartment 20, the battery 30 is detachably secured to the battery holder body 10. For example... Figures 9-10 As shown, the battery cover of the battery 30 is provided with a detachable connection structure 31, the battery holder body 10 is provided with a connection part 11, and the battery compartment of the electronic device is provided with a mounting part (not shown in the figure). The detachable connection structure 31 can cooperate with the mounting part on the electronic device or the connection part 11 of the battery holder body 10. That is, the structure of the connection part 11 of the battery holder body 10 and the mounting part of the electronic device is the same, so that the battery 30 can be connected to the electronic device or the battery holder through the same detachable connection structure 31.

[0051] When the battery body 301 is housed within the electronic device, the battery cover 302 is connected to the mounting portion of the electronic device via a detachable connection structure 31, so that the battery 30 is installed and fixed within the electronic device. When the battery body 301 is housed within the battery compartment 20, the battery cover 302 is connected to the connecting portion 11 of the battery holder via the detachable connection structure 31, so that the battery 30 can be fixed to the battery holder body 10 when housed within the battery compartment 20. Furthermore, the engagement method between the detachable connection structure 31 and the connecting portion 11 can include, but is not limited to, snap-fit, plug-in, threaded connection, etc., and this embodiment does not impose excessive limitations on these methods.

[0052] In one example, the detachable connection structure 31 engages with the connection portion 11. For example... Figures 9-10 As shown, the detachable connection structure 31 is a hook, a latch, or similar structure, and the connecting part 11 is a slot on the battery holder body 10 that mates with the detachable connection structure 31. The detachable connection structure 31 is retractably mounted on the battery 30. The battery 30 also includes an adjusting member 32 and a telescopic member 33. The adjusting member 32 is connected to the detachable connection structure 31, and the detachable connection structure 31 is movably connected to the battery 30 via the telescopic member 33. Normally, the detachable connection structure 31 extends beyond the surface of the battery 30. When the adjusting member 32 or the detachable connection structure 31 is pressed, the detachable connection structure 31 is subjected to external force, causing it to retract into the battery 30 and causing the telescopic member 33 to undergo elastic deformation. When the external force disappears, the detachable connection structure 31 re-extends out of the battery 30 and engages with other structures. Therefore, when it is necessary to install the battery 30 on the battery holder or electronic device, the battery 30 can be snapped into the battery holder or electronic device by pressing the adjusting member 32 or directly pressing the battery 30 into the mounting position on the battery compartment 20 or electronic device; and when it is necessary to remove the battery 30 from the battery holder or electronic device, the detachable connection structure 31 can be retracted into the battery 30 by pressing the adjusting member 32, so as to facilitate the removal of the battery 30.

[0053] Of course, it is understood that the connection between the battery 30 and the battery holder is not limited to the methods listed in the embodiments of this application. When the structure of the battery 30 is different, those skilled in the art can adjust the structure of the battery compartment 20 according to actual needs, as long as the battery compartment 20 and the battery 30 can cooperate with each other and achieve a detachable fixed connection.

[0054] In some embodiments, there are multiple battery compartments 20 and first protective covers 21. The number of battery compartments 20 and first protective covers 21 is equal. Each battery compartment 20 is used to accommodate one battery 30, and each first protective cover 21 is correspondingly provided to one battery compartment 20. The first protective covers 21 of each battery compartment 20 are relatively independent, thereby providing protection for other battery compartments 20 when one or more battery compartments 20 are used individually, without mutual interference. Figures 1-9 As shown in the embodiment of this application, there are two battery compartments 20 and two first protective covers 21. In actual design and production, those skilled in the art can also set them to three, four or other quantities according to actual needs. This embodiment of the application does not impose too many restrictions on this.

[0055] In some embodiments, the battery holder also includes a connection cable 41 for charging electronic devices. For example... Figures 1-9 As shown, the battery holder can charge the battery 30 of a first electronic device through the battery compartment 20, and can also directly charge a second electronic device through the connecting cable 41. The first and second electronic devices can be the same or different. In one example, the battery holder can charge the same electronic device through the battery compartment 20 or the connecting cable 41, such as charging the battery 30 of a camera, or directly charging the camera. Those skilled in the art can choose the charging method according to actual needs. In another example, the battery holder can charge different electronic devices separately through the battery compartment 20 and the connecting cable 41, such as charging two cameras separately through the battery compartment 20 and the connecting cable 41, or charging the camera's battery 30 through the battery compartment 20 while simultaneously charging a mobile phone through the connecting cable 41. This application embodiment does not impose too many restrictions on the specific charging method of the battery holder; those skilled in the art can choose according to actual needs.

[0056] In one example, the connecting wire 41 has a first connecting end 411 and a second connecting end 412. The first connecting end 411 is fixed to the battery holder body 10 and is electrically connected to the battery disposed inside the battery holder body 10. The second connecting end 412 is movably connected to the battery holder body 10 and is used to electrically connect to an electronic device to charge the electronic device.

[0057] In one example, the battery holder body 10 is further provided with a first receiving groove 42, and the connecting cable 41 has a used state and a stored state. When the connecting cable 41 is in the used state, the second connecting end 412 is electrically connected to the electronic device; when the connecting cable 41 is in the stored state, the connecting cable 41 is accommodated in the first receiving groove 42. A fixing part 421 may also be provided in the first receiving groove 42 to fix the connecting cable 41 when it is in the stored state. The fixing part 421 may be a slot for fixing the second connecting end, or a hook, strap, etc., for fixing the connecting cable 41. This application embodiment does not impose too many restrictions on the specific form of the fixing part 421; those skilled in the art can set it according to actual needs.

[0058] In one example, the second connection end 412 is a Type-C connector. Of course, it is understood that those skilled in the art can also set the second connection end 412 to other types of connection ends according to actual needs, such as a 3.5mm round hole connector, a USB (Universal Serial Bus) connector, an Apple universal connector, or a three-in-one connector of Type-C+USB+Apple, etc. The embodiments of this application do not impose too many restrictions on this.

[0059] In one example, the first receiving slot 42 is located on the surface of the battery holder body 10 away from the opening of the battery compartment 20. Figure 7 Taking the orientation shown as an example, in this embodiment of the application, the opening of the battery compartment 20 is located on the top surface of the battery holder body 10, and the first receiving groove 42 is located on the side and bottom surfaces of the battery holder body 10. Of course, it can be understood that the first receiving groove 42 may be located on only one side or on multiple surfaces. This embodiment of the application does not impose too many restrictions on this, and those skilled in the art can set it as needed.

[0060] In some embodiments, the battery holder also includes a memory card compartment 50. The memory card compartment 50 is used to hold a memory card (not shown), facilitating the carrying of the memory card and preventing its loss. Figure 2 , Figure 7 As shown, the memory card compartment 50 includes a second receiving slot 51 and a third receiving slot 511. The third receiving slot 511 is disposed within the second receiving slot 51 and is used to receive the memory card. The opening area of ​​the second receiving slot 51 is larger than the opening area of ​​the third receiving slot 511 to facilitate the removal of the memory card.

[0061] In some embodiments, when the memory card is placed in the memory card compartment 50, the memory card is at least partially received in the third receiving slot 511. In one example, the memory card is fully received in the third receiving slot 511, which may have a notch (not shown) to allow the user to remove the memory card through the notch. In another example, the memory card is partially received in the third receiving slot 511, with the remaining portion protruding from the third receiving slot 511 and received in the second receiving slot 51, allowing the user to directly remove the memory card from the third receiving slot 511.

[0062] In some embodiments, the battery holder further includes a second protective cover 52 for protecting the memory card compartment 50. For example... Figure 2 , Figure 7 As shown, the second protective cover 52 is movably connected to the battery holder body 10, and the second protective cover 52 can move relative to the battery holder body 10 between a third position and a fourth position. When the second protective cover 52 is in the third position, the second protective cover 52 blocks the opening of the second receiving slot 51 to protect the memory card and prevent dust, moisture and other impurities from entering the memory card compartment 50 and causing the memory card to malfunction. It can also prevent the memory card from falling out and being lost due to vibration. When the second protective cover 52 is in the fourth position, the projection of the second protective cover 52 on the battery holder body 10 does not coincide with the projection of the third receiving slot 511 on the battery holder body 10, and the memory card can be exposed, making it convenient for the user to remove the memory card.

[0063] In some embodiments, such as Figure 2 , Figure 7 As shown, the second protective cover 52 is provided with a first connecting portion (not shown in the figure), and the battery holder body 10 is provided with a second connecting portion 16. The first connecting portion and the second connecting portion 16 are slidably connected, thereby allowing the second protective cover 52 to move between a third position and a fourth position.

[0064] In one example, a limiting part 15 is also provided on the battery holder body 10. For example... Figure 2 , Figure 7 As shown, the limiting part 15 is used to limit the movement of the second protective cover 52 relative to the battery holder body 10, while preventing the first connecting part and the second connecting part 16 from separating.

[0065] In one example, the second protective cover 52 also includes a press-down portion 521. For example... Figure 2 , Figure 7 As shown, the pressing part 521 is provided on the side surface of the second protective cover 52 away from the second receiving groove 51. The pressing part 521 can be a structure that can increase friction, such as stripes or frosting, or a structure that is easy to hold, such as a recess, a protrusion, or a handle, so as to facilitate the user to push the second protective cover 52 to move.

[0066] In some embodiments, the battery holder body 10 has at least one decorative surface 101. The decorative surface 101 may be, for example, the side of the battery holder body 10 opposite to the memory card compartment 20. Of course, it is understood that the battery holder body 10 may also have multiple decorative surfaces. The decorative surface 101 is provided with a decorative portion, which includes at least one of a textured structure and a planar pattern (not shown in the figure). The textured structure may, for example, be... Figure 1 The striped structure shown can also be other textures such as wavy lines, sawtooth patterns, or frosted surfaces. The planar pattern can be a design applied to the surface through methods such as painting, printing, or film application. This application does not impose excessive restrictions on the specific method of setting the decorative surface 101; those skilled in the art can choose according to actual needs.

[0067] In some embodiments, the battery holder also includes a charging interface 12. For example... Figures 1-7 As shown, the charging interface 12 is electrically connected to the battery located inside the battery holder body 10. The charging interface 12 is used to charge the battery to realize the charging and battery life function of the battery holder.

[0068] In some embodiments, the battery holder also includes a button 13. For example... Figures 1-7 As shown, button 13 is used to switch the battery holder between sleep and wake-up states. When the battery holder is in sleep state, it is used to store the battery 30; when the battery holder is in wake-up state, it is used to store the battery 30 and charge the battery 30.

[0069] In some embodiments, the battery holder also includes an indicator light 14. For example... Figures 1-7 As shown, indicator light 14 is disposed on the surface of battery holder body 10, and indicator light 14 is used to display as shown. Figure 9 The charging state of battery 30 shown.

[0070] In one example, there is one indicator light 14. The indicator light 14 can be turned off when the battery holder is in a sleep state or when the battery holder is in a wake state but the battery compartment 20 does not contain a battery 30, and can be turned on when the battery holder is in a wake state and the battery compartment 20 contains a battery 30, to indicate whether a battery 30 is charging.

[0071] In another example, there are multiple indicator lights 14, and the number of indicator lights 14 is equal to the number of battery compartments 20. Each indicator light 14 is set to correspond to one battery compartment 20, so as to intuitively show whether each battery compartment 20 is charging the battery 30.

[0072] Of course, it is understood that in this embodiment, the indicator light 14 being off indicates that the battery 30 is not charging, and the indicator light 14 being on indicates that the battery 30 is charging. In actual production, the indicator light 14 can also be on to indicate that it is not charging and off to indicate that it is charging. Furthermore, the indicator light 14 can be a bar shape. The bar-shaped indicator light 14 can be fully or partially displayed according to the battery level of the battery 30, or multiple indicator lights 14 can be fully, partially, or not displayed according to the battery level of the battery 30. The color, number, shape, location, and display method of the indicator lights 14 can all be set according to actual needs, and this embodiment does not impose excessive restrictions on them.
