Description

Technical Field

[0001] This invention relates to the field of action camera technology, and in particular to a charging case and camera assembly. Background Technology

[0002] Compared to regular cameras, action cameras are miniature cameras designed for capturing shots in action-oriented scenarios such as cycling, skiing, diving, and running. They can also be mounted on animals, reducing the burden during exercise compared to regular cameras. Furthermore, their compact size makes installation easier in various scenarios, such as mounting on helmets, chest straps, or motorcycle mounts. In related technologies, action cameras are equipped with a charging case. The camera needs to be placed inside the charging compartment of the case to charge. After charging, it can be removed from the charging case. The charging case has a locking mechanism to secure the action camera and an unlock button to release it. However, some technologies use two latches to lock the action camera, but the unlock button only activates one latch at a time. The other latch releases the camera by deforming, resulting in a less effective unlocking mechanism and affecting the ease of removing the camera. Summary of the Invention

[0003] The main objective of this invention is to provide a charging box for charging a shooting device, aiming to solve the technical problem of how to improve the unlocking effect of the shooting device.

[0004] To achieve the above objectives, the charging case proposed in this invention includes:

[0005] The housing has a mounting cavity and a charging slot for accommodating the shooting device. The charging slot has a first through hole and a second through hole on two opposite slot walls, and both the first through hole and the second through hole communicate with the mounting cavity.

[0006] A locking structure includes an unlocking key, a sliding member, a first latch, and a second latch. The housing has a mounting hole communicating with the mounting cavity. The unlocking key is pressably mounted in the mounting hole. One end of the unlocking key protrudes from the housing and the other end extends into the mounting cavity. The sliding member is slidably mounted in the mounting cavity and connected to the unlocking key. The unlocking key is used to drive the sliding member to slide when pressed.

[0007] The first latch and the second latch are both located in the mounting cavity. The first latch and the second latch extend into the charging slot through the first through hole and the second through hole, respectively, to lock the shooting device housed in the charging slot. The first latch is connected to the sliding member to move with the sliding member. The second latch is movably mounted in the mounting cavity and is tractably connected to the sliding member. The sliding member is used to push the first latch out of the charging slot when pushed by the unlock button, and to drive the second latch to move in the direction of exiting the charging slot, so as to unlock the shooting device housed in the charging slot.

[0008] Optionally, the locking structure further includes a reverse transmission member, which is rotatably mounted in the mounting cavity. The reverse transmission member has a first transmission end and a second transmission end located on both sides of its rotation axis. The first transmission end cooperates with the sliding member, and the second transmission end cooperates with the second latch. When the sliding member is pushed by the unlocking key, it slides in a first direction and drives the first transmission end and the second transmission end to rotate, so that the second transmission end drives the second latch to move in a second direction, wherein the first direction and the second direction are opposite directions.

[0009] Optionally, the sliding member includes a sliding plate and a transmission part connected to one end of the sliding plate. The transmission part is connected to the unlocking key, and the first latch is connected to the end of the sliding plate away from the transmission part. The sliding plate has a transmission groove close to the transmission part. The first transmission end cooperates with the transmission groove, and the second latch is located between the transmission part and the reverse transmission member.

[0010] Optionally, the first latch includes a first mounting portion and a first locking tongue. The first mounting portion is mounted on the end of the sliding plate away from the transmission portion, and the first locking tongue extends into the charging slot through the first through hole. The second latch includes a second mounting portion and a second locking tongue. The second mounting portion is slidably mounted on the sliding plate, the second transmission end abuts against the second mounting portion, and the second locking tongue is connected to the end of the second mounting portion away from the sliding plate. The second locking tongue extends into the charging slot through the second through hole. A supporting rib protrudes from the end of the second mounting portion near the sliding plate, and the supporting rib slidably abuts against the sliding plate. The second locking tongue protrudes in the first direction, and the supporting rib protrudes in the second direction.

[0011] Optionally, the locking mechanism further includes a first reset member disposed in the mounting cavity. One end of the first reset member is connected to the first latch and the other end is connected to the cavity wall of the mounting cavity. The first reset member is used to reset the first latch in the second direction, so as to reset the first latch in the direction of extending into the charging slot.

[0012] And / or, the locking mechanism further includes a second reset member disposed in the mounting cavity, one end of the second reset member being connected to the second latch and the other end being connected to the cavity wall of the mounting cavity, the second reset member being used to reset the second latch toward the first direction, so as to reset the second latch toward the direction of extending into the charging slot.

[0013] Optionally, the sliding member includes a sliding plate and a transmission part connected to one end of the sliding plate. The transmission part is connected to the unlocking key. The first latch is connected to the end of the sliding plate away from the transmission part. The second latch is rotatably mounted in the mounting cavity. The second latch has a transmission end and a latch end located on both sides of its rotation axis. The transmission end is tractably connected to the sliding plate. The latch end extends into the charging slot. When the sliding member is pushed by the unlocking key, it drives the transmission end to rotate so that the latch end rotates in the direction of exiting the charging slot.

[0014] Optionally, the sliding plate has a transmission protrusion located between the transmission part and the second latch. When the sliding member is pushed by the unlocking key, the transmission protrusion moves with the sliding plate and pushes the transmission end to rotate, so that the latch end rotates to exit the charging slot.

[0015] Optionally, the locking structure further includes an elastic reset member disposed in the mounting cavity. One end of the elastic reset member is connected to the transmission part and the other end is connected to the housing. The elastic reset member is used to reset the sliding member toward the mounting hole, thereby driving the first latch to reset toward the direction of extending into the charging slot.

[0016] And / or, the mounting cavity is provided with a rotating shaft, the second latch is rotatably engaged with the rotating shaft, and the locking structure further includes a reset torsion spring sleeved on the rotating shaft, one end of the reset torsion spring abutting against the second mounting part, the reset torsion spring being used to reset the locking tongue end toward the direction of extending into the charging slot.

[0017] Optionally, the sliding plate is provided with a limiting groove that extends along the movement direction of the sliding plate, and the box body is provided with a limiting protrusion that extends into the limiting groove to limit the movement displacement of the sliding plate.

[0018] The present invention also proposes a camera assembly, including a shooting device and a charging case as described above, wherein the shooting device is detachably mounted in the charging slot of the charging case, and when the shooting device is mounted in the charging slot, a first latch and a second latch of the charging case extend into the charging slot to lock the shooting device.

[0019] In the technical solution of the charging case of this invention, the first latch and the second latch can lock the shooting device housed in the charging slot. When the unlock button is pressed and pushes the slider to move, the first latch can move synchronously with the slider and be pushed out of the charging slot, and the second latch can be driven out of the charging slot by the slider, thereby unlocking the shooting device so that the user can take the shooting device out of the charging slot. When the unlock button is pressed, it can drive both the first latch to release the shooting device and the second latch to release the shooting device. In this way, both the first latch and the second latch can unlock the shooting device by moving, thereby improving the unlocking effect of the shooting device and improving the convenience for the user to take out the shooting device.

[0038] This invention proposes a charging box 100 for charging a shooting device 200, aiming to solve the technical problem of how to improve the unlocking effect of the shooting device 200.

[0039] In embodiments of the present invention, such as Figures 1 to 2As shown, the charging case 100 includes: a case body 10, which has a mounting cavity 12 and a charging slot 11 for accommodating the shooting device 200. The charging slot 11 has two opposing slot walls with opposing first through holes 111 and second through holes 112, both of which communicate with the mounting cavity 12; and a locking structure, which includes an unlocking key 21, a slider 22, a first latch 23, and a second latch 24. The case body 10 has a mounting hole 13 communicating with the mounting cavity 12. The unlocking key 21 is pressably mounted in the mounting hole 13. One end of the unlocking key 21 is exposed outside the case body 10, and the other end extends into the mounting cavity 12. The slider 22 is slidably mounted in the mounting cavity 12 and connected to the unlocking key 21. The unlocking key 21 is used to drive the slider 22 to slide when pressed.

[0040] The first latch 23 and the second latch 24 are both located in the mounting cavity 12. The first latch 23 and the second latch 24 extend into the charging slot 11 through the first through hole 111 and the second through hole 112, respectively, to lock the shooting device 200 housed in the charging slot 11. The first latch 23 is connected to the slider 22 to move with the slider 22. The second latch 24 is movably mounted in the mounting cavity 12 and is tractably connected to the slider 22. The slider 22 is used to drive the first latch 23 out of the charging slot 11 and drive the second latch 24 to move in the direction of exiting the charging slot 11 when pushed by the unlock button 21, so as to unlock the shooting device 200 housed in the charging slot 11.

[0041] In this embodiment, the shooting device 200 includes, but is not limited to, action cameras, drones, digital cameras, etc. The housing 10 is generally rectangular, but can also be cylindrical or irregularly shaped. The shooting device 200 is detachably housed in the charging slot 11; that is, the shooting device 200 can be inserted into the charging slot 11 and removed from it. The charging case 100 also includes a power supply battery, a main control board, electrical connectors, and control buttons. The power supply battery is installed inside the housing 10; the electrical connectors are installed inside the housing 10 and electrically connected to the main control board, with at least a portion exposed at the bottom or wall of the charging slot 11 for electrical connection to the shooting device 200 installed in the charging slot 11; the control buttons are installed in the housing 10 and electrically connected to the main control board, and are used to control the shooting device 200 installed in the charging slot 11.

[0042] When the shooting device 200 is installed in the charging slot 11, the charging portion of the shooting device 200 is connected to or abuts against the electrical connector inside the charging slot 11. For example, the shooting device 200 has a battery and exposed charging contacts. The battery is electrically connected to the charging contacts. The electrical connector includes a conductive pin, one end of which is exposed outside the wall of the charging slot 11, and the other end is electrically connected to the main control board. When the shooting device 200 is installed in the charging slot 11, the charging contacts abut against the end of the conductive pin, thereby achieving electrical connection between the main control board and the battery of the shooting device 200. The main control board can distribute electrical energy to the shooting device 200 and transmit control signals. The power supply battery can be charged by mains power to store electrical energy. When the charging box 100 is working, the power supply battery provides electrical energy to the main control board, which then distributes the electrical energy to the battery of the shooting device 200.

[0043] The charging case 100 not only charges the shooting device 200 but also allows the user to control the shooting device 200 via control keys. The control components are exposed on the surface of the case 10. These control keys can be buttons or touch keys, without limitation. When the control components are pressed or touched, they generate an electrical signal, which is then transmitted by the main control board to the shooting device 200 to control it. The control keys may include a power button, a shutter button, and a switching button. The power button controls the charging case 100 to turn on and off, the shutter button controls the shooting device 200 to take photos or record videos, and the switching button controls switching between different modes and selecting different parameters of the shooting device 200.

[0044] The housing 10 has adjacent first and second sidewalls. The opening of the charging slot 11 is located on the first sidewall, and the mounting hole 13 is located on the second sidewall, with the mounting hole 13 situated on one side of the width direction of the charging slot 11. The slider 22 has an initial locked position and an unlocked position after being pushed by the unlock button 21. When the slider 22 is in the locked position, the first latch 23 and the second latch 24 extend into the charging slot 11 from two opposite slot walls, respectively. At this time, the first latch 23 and the second latch 24 can abut or lock the shooting device 200 inside the charging slot 11, thereby restricting the shooting device 200 from detaching from the charging slot 11 and ensuring the installation stability of the shooting device 200 within the charging slot 11.

[0045] When the unlock button 21 is pressed, it pushes the slider 22 from the locked position to the unlocked position. At this time, the first latch 23 moves synchronously with the slider 22 and exits the charging slot 11. The second latch 24 can move in the opposite direction to the first latch 23 under the action of the movement of the slider 22, thereby exiting the charging slot 11. After the first latch 23 and the second latch 24 exit the charging slot 11, the shooting device 200 can be released, so that the shooting device 200 can be removed from the charging slot 11.

[0046] When the unlock button 21 is pressed, it can both drive the first latch 23 to release the shooting device 200 and drive the second latch 24 to release the shooting device 200. In this way, both the first latch 23 and the second latch 24 can unlock the shooting device 200 by moving, thereby improving the unlocking effect of the shooting device 200 and improving the convenience for the user to take out the shooting device 200.

[0047] The first latch 23 can move by sliding along a straight line, rotating, or in other ways, without limitation. The following description elaborates on embodiments of the two specific movement modes of the first latch 23: sliding along a straight line and rotating.

[0048] In one embodiment, such as Figures 2 to 4 As shown, the locking structure further includes a reverse transmission member 30, which is rotatably mounted in the mounting cavity 12. The reverse transmission member 30 has a first transmission end and a second transmission end located on both sides of its rotation axis. The first transmission end cooperates with the sliding member 22, and the second transmission end cooperates with the second latch 24. When the sliding member 22 is pushed by the unlocking key 21, it slides in a first direction and drives the first transmission end and the second transmission end to rotate, so that the second transmission end drives the second latch 24 to move in a second direction, wherein the first direction and the second direction are opposite directions.

[0049] When the reverse transmission member 30 rotates, the rotational tangent direction of the first transmission end is opposite to that of the second transmission end. When the slider 22 moves in the first direction, it can push the first transmission end, thereby causing the first and second transmission ends to rotate synchronously. The second transmission end then pushes the second latch 24 to slide, thus allowing the second latch 24 to slide in the second direction, that is, in the opposite direction to the slider 22. The reverse transmission member 30 drives the second latch 24 by rotation, which simplifies the structure and transmission method of the reverse transmission member 30, thereby simplifying the internal structure of the charging box 100.

[0050] When the unlock button 21 is pressed, it pushes the slider 22 from the locked position to the unlocked position. At this time, the first latch 23 and the slider 22 move synchronously and exit the charging slot 11. The reverse transmission member 30 can convert the force of the slider 22 in the first direction into a transmission force in the second direction and apply it to the second latch 24. Under the action of the reverse transmission member 30, the second latch 24 slides in the opposite direction to the first latch 23, thereby exiting the charging slot 11. After the first latch 23 and the second latch 24 exit the charging slot 11, the shooting device 200 can be released, so that the shooting device 200 can be removed from the charging slot 11.

[0051] When the unlock button 21 is pressed, it can both drive the first latch 23 to release the shooting device 200 and drive the second latch 24 to release the shooting device 200. In this way, both the first latch 23 and the second latch 24 can unlock the shooting device 200 by sliding, thereby improving the unlocking effect of the shooting device 200 and improving the convenience for the user to take out the shooting device 200.

[0052] The sliding member 22 includes a sliding plate 25 and a transmission part 26 connected to one end of the sliding plate 25. The transmission part 26 is connected to the unlocking key 21. The first latch 23 is connected to the end of the sliding plate 25 away from the transmission part 26. The sliding plate 25 has a transmission groove 253, which is close to the transmission part 26. The first transmission end cooperates with the transmission groove 253. The second latch 24 is located between the transmission part 26 and the reverse transmission member 30.

[0053] The sliding plate 25 passes under the charging slot 11, and the transmission part 26 is located between the second latch 24 and the unlocking button 21. The unlocking button 21 can push the sliding plate 25 through the transmission part 26, and the sliding plate 25 drives the first locking tongue 232 out of the charging slot 11. The first transmission end is located below the rotating shaft 14 of the reverse transmission member 30, and the second transmission end is located above the rotating shaft 14 of the reverse transmission member 30. The first transmission end extends into the transmission groove 253. When the sliding plate 25 slides, the groove wall of the transmission groove 253 pushes the first transmission end to drive the reverse rotating member to rotate. In this way, it can prevent the sliding plate 25 from getting stuck in the process of driving the first transmission end, and it can also simplify the cooperation between the sliding plate 25 and the first transmission end.

[0054] Specifically, such as Figures 2 to 4 As shown, the first latch 23 includes a first mounting portion 231 and a first latch 232. The first mounting portion 231 is mounted on the end of the sliding plate 25 away from the transmission portion 26, and the first latch 232 extends into the charging slot 11 through the first through hole 111. The second latch 24 includes a second mounting portion 241 and a second latch 242. The second mounting portion 241 is slidably mounted on the sliding plate 25, and the second transmission end abuts against the second mounting portion 241. The second latch 242 is connected to the end of the second mounting portion 241 away from the sliding plate 25, and the second latch 242 extends into the charging slot 11 through the second through hole 112. A support rib 244 protrudes from the end of the second mounting portion 241 near the sliding plate 25. The support rib 244 slidably abuts against the sliding plate 25. The second latch 242 protrudes in the first direction, and the support rib 244 protrudes in the second direction.

[0055] The first mounting part 231 and the first locking tongue 232 are connected in a "7" shape, and the second mounting part 241 and the second locking tongue 242 are connected in a "7" shape. This ensures both the installation stability of the first latch 23 and the second latch 24, and the locking effect on the shooting device 200. When the second latch 24 slides, the second locking tongue 242 slides along the wall of the second through hole 112, and the support rib 244 slides along the sliding plate 25. This ensures that the upper and lower ends of the second latch 24 are evenly stressed and can be supported during sliding. The support rib 244 increases the sliding contact area between the second mounting part 241 and the sliding plate 25, thereby improving the sliding stability of the second mounting part 241 on the sliding plate 25 and preventing the second mounting part 241 from getting stuck or falling over during sliding.

[0056] For example, such as Figures 2 to 4 As shown, the locking mechanism further includes a first reset member 31 disposed in the mounting cavity 12. One end of the first reset member 31 is connected to the first latch 23 and the other end is connected to the cavity wall of the mounting cavity 12. The first reset member 31 is used to reset the first latch 23 in the second direction, so as to reset the first latch 23 in the direction of extending into the charging slot 11.

[0057] The first reset member 31 can be a spring. When the unlock button 21 is pressed, causing the first latch 23 to move in the first direction, the first reset member 31 is compressed and generates elastic potential energy. After the unlock button 21 resets or the pressing force is removed, the first latch 23 is no longer pushed by the sliding member 22. At this time, the first reset member 31 recovers its deformation and releases kinetic energy, thereby pushing the first latch 23 to reset, so that the first locking tongue 232 resets to extend into the charging slot 11. That is to say, the first locking tongue 232 will automatically reset and lock the shooting device 200 inserted into the charging slot 11 without the need for manual operation by the user, thereby improving the ease of use of the charging box 100. It can be understood that while the first reset member 31 pushes the first latch 23 to reset, the force will also be transmitted to the sliding plate 25, thereby pushing the sliding member 22 to reset. The sliding member 22 then drives the reverse transmission member 30 to reset, so that the force acting on the second latch 24 in the second direction is removed.

[0058] Specifically, such as Figures 2 to 4 As shown, the locking mechanism further includes a second reset member 32 disposed in the mounting cavity 12. One end of the second reset member 32 is connected to the second latch 24, and the other end is connected to the limiting part 121 or the cavity wall of the mounting cavity 12. The second reset member 32 is used to reset the second latch 24 toward the first direction, so as to reset the second latch 24 toward the direction of extending into the charging slot 11.

[0059] The second reset member 32 can be a spring. When the unlock button 21 is pressed, causing the sliding member 22 to drive the second latch 24 to move in the second direction via the reverse transmission member 30, the second reset member 32 is compressed and generates elastic potential energy. After the unlock button 21 resets or the pressing force is removed, the reverse transmission member 30 is no longer pushed by the sliding member 22, and the second latch 24 is no longer pushed by the reverse transmission member 30. At this time, the second reset member 32 restores its deformation and releases kinetic energy, thereby pushing the second latch 24 to reset, so that the second locking tongue 242 resets to extend into the charging slot 11. That is to say, the second locking tongue 242 automatically resets and locks the shooting device 200 inserted into the charging slot 11 without the need for manual operation by the user, thereby improving the ease of use of the charging box 100.

[0060] In practical applications, such as Figure 4 As shown, the side of the first locking tongue 232 facing the opening of the charging slot 11 forms a first guide slope 234. The first guide slope 234 is used to slide against the shooting device 200 so that when the shooting device 200 is inserted into the charging slot 11, it will squeeze the first locking tongue 232 out of the charging slot 11.

[0061] The first guide slope 234 is inclined towards the opening of the charging slot 11. The shooting device 200 is inserted into the charging slot 11 along its depth direction. During this process, the shooting device 200 gradually presses the first locking tongue 232 along the depth direction of the charging slot 11. The first guide slope 234 can make the pressing force of the shooting device 200 on the first locking tongue 232 generate a component force along the width direction of the charging slot 11. The width direction of the charging slot 11 is also the movable direction of the first latch 23 and the sliding member 22, so that the shooting device 200 can press the first locking tongue 232 out of the charging slot 11. During the process of the first locking tongue 232 being squeezed out of the charging slot 11, the sliding member 22 and the reverse transmission member 30 are also driven synchronously, so that the reverse transmission member 30 can drive the second latch 24 to move, so that the second locking tongue 242 also exits the charging slot 11.

[0062] The second locking tongue 242 forms a second guide slope 245 on the side facing the opening of the charging slot 11. The second guide slope 245 is used to slide against the shooting device 200 so that when the shooting device 200 is inserted into the charging slot 11, it will squeeze the second locking tongue 242 out of the charging slot 11.

[0063] The second guide slope 245 is inclined toward the opening of the charging slot 11. The shooting device 200 is inserted into the charging slot 11 along the depth direction of the charging slot 11. During this process, the shooting device 200 will gradually press the second locking tongue 242 along the depth direction of the charging slot 11. The second guide slope 245 can make the pressing force of the shooting device 200 on the second locking tongue 242 generate a component force along the width direction of the charging slot 11. The width direction of the charging slot 11 is also the movable direction of the second latch 24, so that the shooting device 200 can press the second locking tongue 242 out of the charging slot 11.

[0064] In another embodiment, such as Figures 5 to 8 As shown, the sliding member 22 includes a sliding plate 25 and a transmission part 26 connected to one end of the sliding plate 25. The transmission part 26 is connected to the unlocking key 21. The first latch 23 is connected to the end of the sliding plate 25 away from the transmission part 26. The second latch 24 is rotatably mounted in the mounting cavity 12. The second latch 24 has a transmission end and a latch end located on both sides of its rotation axis. The transmission end is tractably connected to the sliding plate 25. The latch end extends into the charging slot 11. When the sliding member 22 is pushed by the unlocking key 21, it drives the transmission end to rotate so that the latch end rotates in the direction of exiting the charging slot 11.

[0065] The first latch 23 includes a first mounting portion 231 and a first latch 232. The first mounting portion 231 is mounted on the end of the sliding plate 25 away from the transmission portion 26, and the first latch 232 extends into the charging slot 11. The second latch 24 includes a second mounting portion 241 and a second latch 242. The second mounting portion 241 is rotatably mounted in the mounting cavity 12, and the second latch 242 extends into the charging slot 11, forming the latch end of the second latch 24. The end of the second mounting portion 241 away from the second latch 242 forms the transmission end of the second latch 24. When the sliding plate 25 drives the first latch 232 out of the charging slot 11, the sliding plate 25 synchronously drives the transmission end to rotate. The rotation tangent direction of the latch end is opposite to the rotation tangent direction of the transmission end, thereby allowing the second latch 242 to rotate out of the charging slot 11.

[0066] The sliding plate 25 passes under the charging slot 11, and the transmission part 26 is located between the second latch 24 and the unlocking button 21. The unlocking button 21 can push the sliding plate 25 through the transmission part 26, and the sliding plate 25 drives the first locking tongue 232 to exit the charging slot 11. The second latch 24 can rotate around the axis of the second mounting part 241, and the second locking tongue 242 is located above the axis of the second mounting part 241. When the sliding plate 25 is pushed, it can push the second mounting part 241 towards the second through hole 112, thereby causing the second locking tongue 242 to rotate and exit the charging slot 11 through the lever action. In this way, the driving method of the sliding member 22 for the first latch 23 and the second latch 24 can be simplified, thereby reducing the installation difficulty of the locking structure in the box 10 and improving the overall assembly convenience of the charging box 100.

[0067] Specifically, such as Figure 7 and Figure 8 As shown, the sliding plate 25 has a transmission protrusion 251. The transmission protrusion 251 is located between the transmission part 26 and the second latch 24. When the sliding member 22 is pushed by the unlocking key 21, the transmission protrusion 251 moves with the sliding plate 25 and pushes the transmission end to rotate, so that the latch end rotates to exit the charging slot 11.

[0068] The transmission protrusion 251 is located below the axis of the second mounting portion 241. When the sliding plate 25 is pushed, the transmission protrusion 251 moves synchronously, pushing the second mounting portion 241 towards the second through hole 112. This allows the second latch 242 to rotate and exit the charging slot 11 via a lever action. The transmission protrusion 251 has a transmission ramp that is inclined towards the axis of the second mounting portion 241 and forms an angle with the direction of movement of the sliding member 22. The second mounting portion 241 has a force-receiving ramp corresponding to the transmission ramp, which forms an angle with the direction of movement of the sliding member 22. When the transmission protrusion 251 pushes the second mounting portion 241, the transmission ramp and the force-receiving ramp abut against each other, allowing the second mounting portion 241 to be pushed more smoothly and rotated along a preset trajectory, ensuring that the second latch 242 can be rotated out of the charging slot 11.

[0069] For example, such as Figures 6 to 8 As shown, the locking structure also includes an elastic reset member 27 disposed in the mounting cavity 12. One end of the elastic reset member 27 is connected to the transmission part 26 and the other end is connected to the housing 10. The elastic reset member 27 is used to reset the sliding member 22 toward the mounting hole 13, so as to drive the first latch 23 to reset toward the direction of extending into the charging slot 11.

[0070] The elastic reset member 27 can be a spring. When the unlock button 21 is pressed, causing the transmission part 26 to move away from the mounting hole 13, the elastic reset member 27 is compressed and generates elastic potential energy. After the unlock button 21 resets or the pressure is removed, the transmission part 26 is no longer pushed by the unlock button 21. At this time, the elastic reset member 27 recovers its deformation and releases kinetic energy, thereby pushing the sliding member 22 back to the locked position. In this way, the first latch 23 mounted on the sliding plate 25 can also reset synchronously with the sliding member 22, so that the first locking tongue 232 resets to extend into the charging slot 11. That is to say, the first locking tongue 232 automatically resets and locks the shooting device 200 inserted into the charging slot 11 without the need for manual operation by the user, thereby improving the ease of use of the charging box 100.

[0071] Specifically, such as Figure 5 and Figure 8 As shown, the mounting cavity 12 is provided with a rotating shaft 14, and the second latch 24 is rotatably engaged with the rotating shaft 14. The locking structure also includes a reset torsion spring 28 sleeved on the rotating shaft 14. One end of the reset torsion spring 28 abuts against the second mounting part 241. The reset torsion spring 28 is used to reset the latch end toward the direction of extending into the charging slot 11.

[0072] Similarly to the above embodiment, after the unlock button 21 is reset or the pressure applied to it is removed, the transmission part 26 is no longer pushed by the unlock button 21, and the second mounting part 241 is no longer pushed by the transmission protrusion 251. At this time, the reset torsion spring 28 releases kinetic energy, thereby driving the second mounting part 241 to reset and rotate, causing the second locking tongue 242 to rotate and re-enter the charging slot 11. In this way, the second locking tongue 242 will automatically reset and lock the shooting device 200 inserted into the charging slot 11 without the need for manual operation by the user, thereby improving the ease of use of the charging box 100.

[0073] Combining the above embodiments of the first locking bolt 232 and the second locking bolt 242, such as Figures 5 to 8 As shown, the side of the first locking tongue 232 facing the opening of the charging slot 11 forms a guide slope 233, which is used to slide against the shooting device 200 so that the shooting device 200 squeezes the first locking tongue 232 out of the charging slot 11; the side of the second locking tongue 242 facing the opening of the charging slot 11 forms a clearance slope 243, which is used to avoid the shooting device 200 and the hole wall of the second through hole 112 when the second locking tongue 242 exits the charging slot 11.

[0074] The shooting device 200 is inserted into the charging slot 11 along its depth direction. During this process, the shooting device 200 gradually presses the first locking tongue 232 along the depth direction of the charging slot 11. The avoidance slope 243 allows the squeezing force of the shooting device 200 on the first locking tongue 232 to generate a component force along the width direction of the charging slot 11. The width direction of the charging slot 11 is also the movable direction of the first latch 23 and the sliding member 22, thereby allowing the shooting device 200 to squeeze the first locking tongue 232 out of the charging slot 11. During the process of the first locking tongue 232 being squeezed out of the charging slot 11, the sliding member 22 and the transmission protrusion 251 are also driven synchronously, so that the transmission protrusion 251 can drive the second mounting part 241 to rotate, so that the second locking tongue 242 rotates out of the charging slot 11.

[0075] It is understandable that the second locking tongue 242 rotates out of the charging slot 11 at the same time that the shooting device 200 pushes the first locking tongue 232 out of the charging slot 11. At this time, the second locking tongue 242 is relatively close to the shooting device 200, and it is easy for it to obstruct the shooting device 200 during rotation. The avoidance slope 243 can reduce or even avoid contact between the second locking tongue 242 and the shooting device 200 during rotation, so that the avoidance device can rotate out of the charging slot 11 smoothly, and the shooting device 200 can be smoothly installed in the charging slot 11. In addition, during the process of the end of the second locking tongue 242 retracting into the second through hole 112, the avoidance slope 243 can also reduce or even avoid contact between the second locking tongue 242 and the hole wall of the second through hole 112, so that the second locking tongue 242 can retract smoothly into the second through hole 112.

[0076] Therefore, during the insertion of the shooting device 200 into the charging slot 11, the first locking tongue 232 can be temporarily pushed out of the charging slot 11, while the second locking tongue 242 is temporarily pulled out of the charging slot 11, facilitating the installation of the shooting device 200 into the charging slot 11. After the shooting device 200 is installed, the first locking tongue 232 re-enters the charging slot 11 under the action of the elastic reset member 27, and the second locking tongue 242 re-enters the charging slot 11 under the action of the reset torsion spring 28, thereby achieving automatic locking of the shooting device 200 by the first locking tongue 232 and the second locking tongue 242. This further improves the ease of use of the charging box 100.

[0077] For example, such as Figure 7 and Figure 8 As shown, the mounting hole 13 includes a mounting groove and a through hole formed at the bottom of the mounting groove. The unlocking key 21 includes a keycap 211 and a key rod 212. One end of the key rod 212 is connected to the keycap 211 and the other end passes through the through hole. The locking structure also includes a return spring 29. The return spring 29 is located in the mounting groove and sleeved on the key rod 212. The return spring 29 is used to reset the keycap 211 in a direction away from the through hole.

[0078] The keycap 211 is pressed by the user, and the key stick 212 is used to push the slider 22. When the keycap 211 is pressed, the return spring 29 is compressed and generates elastic potential energy; after the pressing force is removed, the return spring recovers its deformation and releases kinetic energy, thereby pushing the unlock key 21 back to its original position. In this way, during the reset process of the slider 22, the unlocking component can also reset itself via the return spring 29, thereby reducing the resistance caused by the unlock key 21 to the reset process of the slider 22, ensuring that the slider 22 can smoothly drive the first latch 23 and the second latch 24 to reset.

[0079] For example, such as Figures 2 to 4 As shown, the sliding plate 25 is provided with a limiting groove 252, which extends along the movement direction of the sliding plate 25. The box body 10 is provided with a limiting protrusion 15, which extends into the limiting groove 252 to limit the movement displacement of the sliding plate 25.

[0080] The limiting protrusion 15 is fixed, while the limiting groove 252 is movable with the sliding plate 25. When the groove wall of the limiting groove 252 abuts against the limiting protrusion 15, the sliding member 22 cannot continue to move. In this way, the movement displacement of the sliding plate 25 can be limited, preventing excessive movement displacement of the sliding plate 25 from making it difficult for the first latch 23 and the second latch 24 to reset, thus ensuring the working stability of the locking structure. The limiting groove 252 has a first groove wall and a second groove wall facing the limiting protrusion 15. The first groove wall and the second groove wall are at right angles at the edge of the groove opening to ensure the abutment effect between the limiting protrusion 15 and the first groove wall or the second groove wall, thereby ensuring the limiting effect on the sliding member 22.

[0081] Specifically, such as Figure 7 and Figure 8 As shown, the box body 10 is provided with an assembly groove, the opening of the assembly groove is opposite to the opening of the charging groove 11, the sliding member 22, the first latch 23, the second latch 24 and the reverse transmission member 30 are installed into the assembly groove through the opening of the assembly groove, the charging box 100 also includes a sealing cover 16, the sealing cover 16 is provided on the opening of the assembly groove, the sealing cover 16 and the assembly groove surround to form the mounting cavity 12.

[0082] The sliding member 22, the first latch 23, and the second latch 24 can be inserted into the mounting cavity 12 from the slot of the assembly groove to reduce the assembly difficulty of the locking structure in the mounting cavity 12. The sealing cover 16 can cover the slot of the assembly groove to prevent foreign objects from entering the mounting cavity 12 and affecting the movement of the sliding member 22, thereby ensuring the working stability of the locking structure.

[0083] like Figure 9As shown, the present invention also proposes a camera assembly, which includes a shooting device 200 and a charging case 100. The specific structure of the charging case 100 is as described in the above embodiments. Since this camera assembly adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The shooting device 200 is detachably mounted on the charging slot 11 of the charging case 100. When the shooting device 200 is mounted on the charging slot 11, the first latch 23 and the second latch 24 of the charging case 100 extend into the charging slot 11 to lock the shooting device 200.

[0084] Specifically, such as Figure 2 As shown, the two back sidewalls of the shooting device 200 are respectively provided with a first locking groove 210 and a second locking groove 220. When the shooting device 200 is installed in the charging slot 11, the first latch 23 locks into the first locking groove 210, and the second latch 24 locks into the second locking groove 220. In this way, the mating area between the first latch 23 and the second latch 24 and the shooting device 200 can be increased, thereby improving the locking effect on the shooting device 200.

[0085] like Figure 10 As shown, the charging slot 11 has a first slot wall, a second slot wall, and a third slot wall. The first slot wall and the second slot wall are arranged opposite to each other. A first through hole 111 is formed in the first slot wall, a second through hole 112 is formed in the second slot wall, and the third slot wall connects the first slot wall and the second slot wall. The third slot wall has a third through hole 113. A third latch 40 and a third reset member 41 are also installed inside the housing 10. The third latch 40 is slidably installed inside the housing 10 and extends into the charging slot 11 through the third through hole 113 to cooperate with the first latch 23 and the second... The latches 24 together lock the shooting device 200 housed in the charging slot 11. One end of the third reset member 41 is connected to the housing 10 and the other end is connected to the third latch 40. The third reset member 41 is used to reset the third latch 40 in the direction of extending into the charging slot 11. The side of the third latch 40 facing the charging slot 11 forms a third guide slope 42. The third guide slope 42 is used to slide against the shooting device 200 so that when the shooting device 200 is inserted into the charging slot 11, it presses the third latch 40 in the direction of exiting the charging slot 11.

[0086] The shooting device 200 has a third locking groove 230 on its side wall facing the third slot wall. When the shooting device 200 is installed in the charging slot 11, the third latch 40 locks into the third locking groove 230. Thus, the third latch 40, together with the first latch 23 and the second latch 24, locks the shooting device 200 from three positions, improving the locking effect. When it is necessary to remove the shooting device 200 from the charging slot 11, the unlock button 21 can be pressed first to unlock the first latch 23 and the second latch 24. Then, a disassembly force is applied to the end of the shooting device 200 away from the third latch 40 to move that end out of the charging slot 11 first. During this process, the shooting device 200 rotates to a certain extent. During this rotation, the third locking groove 230 can naturally disengage from the third latch 40, thus eliminating the need to unlock the third latch 40 and simplifying the removal of the shooting device 200.

[0087] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
