DETAILED DESCRIPTION

[0044] The following will be combined with the attached Figure 1 To Attachment Fig.12 The technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] Small cameras are now widely used, especially by some live broadcasters, store visitors and other staff. Therefore, small cameras need to be kept powered at all times. In order to keep the small camera powered, an external charger is usually provided for the small camera. However, the operation of the existing charger is relatively complicated when it is assembled with the small camera. The clamping part needs to be clamped at the same time to make the clamping part open, and the clamping part needs to be released after the small camera is placed in order to clamp and fix the small camera. In addition, the internal structure is also relatively complicated, which is not conducive to production.

[0046] In this regard, the applicant provides a charger that can release the clamping part by pressing a button. After the small camera is placed in the charger, the pressing part is released to allow the clamping part to automatically clamp the small camera to achieve a stable clamping of the small camera. This effectively solves the technical problem in the prior art that the clamping part needs to be pressed at the same time to open the clamping part to achieve a fixed small camera, which is very cumbersome to operate. The technical solution is simple to operate, has a simple internal structure, and is easy to produce.

[0047] like Figure 1 to Figure 2 As shown, a charger of the present technical solution has a charging body 1, and the charging body 1 is a rectangular three-dimensional structure, but it is certainly not limited to this shape, and structures of any other shape are within the protection scope of the present technical solution. Figure 1 As shown in the figure, the top 11 of the charging body 1 is connected to an external device, such as an anti-shake gimbal or a small camera, and the top of the charging body 1 is also provided with a charging output port 15. Figure 2 As shown, one end of the charging output port 15 is exposed on the surface of the top 11 for electrical connection with an external device. The other end of the charging output port 15 is arranged inside the charging body 1, that is, in the storage cavity 18 of the charging body 1, and is electrically connected to the circuit control board 16 provided in the storage cavity 18. The storage cavity 18 is also provided with a battery 17, and the battery 17 is used to provide power to the external device. The circuit control board 16 also has a display light, which is used to display the battery power, and a light-transmitting plate 5 is provided on the outside of the charging body 1 corresponding to the setting position of the display light. The light-transmitting plate 5 is used for the display light to transmit light, so as to facilitate the user to query the battery power display.

[0048] like Figure 3 As shown, the charging body 1 also has four side walls 12, namely an upper side wall 121, a lower side wall 122, a left side wall 123 and a right side wall 124, wherein the upper side wall 121 and the lower side wall 122 are arranged opposite to each other, and the left side wall 123 and the right side wall 124 are also arranged opposite to each other. A charging input port 19 is provided on the surface of the upper side wall 121 or the lower side wall 122, and the charging input port 9 is electrically connected to the line control 16 and the battery 17 to realize charging of the charger.

[0049] like Figures 4 to 5As shown, the charging body 1 also has a locking device 2, which is partially exposed on the surface of the side wall 12 and partially arranged in the storage cavity 18. The locking device 2 includes an unlocking structure 21, a linkage structure 22, a locking structure 23 and a reset structure 24. Part of the unlocking structure 21 and part of the locking structure 23 are exposed on the outer surface of the side wall 12 of the charging body 1. The part of the unlocking structure 21 and the part of the locking structure 23 arranged in the storage cavity 18 are connected by a linkage structure 22, so that when the unlocking structure 21 moves, the locking structure 23 can also make a preset movement.

[0050] It should be noted that the unlocking structure 21 exposed on the outer surface of the side wall 12 facilitates the user to operate the charger. The locking structure 23 exposed on the left side wall 123 and the right side wall 124 of the charging body 1 is used to clamp and connect external devices, such as an anti-shake gimbal, a small camera, etc.

[0051] Specifically, the user can press the portion of the unlocking structure 21 exposed on the outer surface of the side wall 12 to close or release the locking structure 23, thereby clamping or releasing the external device.

[0052] like Figure 5 As shown, a charger of the present technical solution includes a charging body 1, one end of the charging body 1 has a locking device 2, and the locking device 2 has an unlocking structure 21, a linkage structure 22, a locking structure 23 and a reset structure 24.

[0053] The unlocking structure 21 and the locking structure 23 are partially exposed on the outer surface of the side wall 12, and the rest are arranged in the storage cavity 18. The unlocking structure 21 and the locking structure 23 arranged in the storage cavity 18 are connected by the linkage structure 22. The linkage structure 22 is arranged between the unlocking structure 21 and the locking structure 23, and transmits the movement of the unlocking structure 21 to the unlocking structure 21, so that the locking structure 23 can make a closing or releasing action. The reset structure 24 is arranged in the storage cavity 18 and is arranged to be in relative contact with the part of the locking structure 23 arranged in the storage cavity 18.

[0054] like Figure 5 to Figure 6As shown, the unlocking structure 21 includes a pressing portion 211, and the pressing portion 211 is partially exposed on the surface of the charging body 1 and is in its initial position on the surface of the charging body 1. The pressing portion 211 is connected to a first connecting portion 212; the locking structure 23 includes a clamping portion 231, and the clamping portion 231 is closed and connected to the charging body 1, that is, the first clamping end 2311 of the clamping portion 231 is closely connected from the outer side wall of the charging body 1 and extends to the edge of the top 11; one end of the linkage structure 22 is connected to the first connecting portion 212 is connected, and the other end of the linkage structure 22 is connected to the clamping part 231; when the pressing part is subjected to an external force 211, the pressing part 211 drives the first connecting part 212 to push the linkage structure 22 to squeeze the clamping part 231 so that the clamping part 231 changes from a closed state to an open state, that is, moves from position C to position D; when the clamping part 231 changes from an open state to a closed state, the reset structure 24 and the clamping part 231 change from a tight connection to a loose connection, and the pressing part 211 returns to its initial position.

[0055] It should be understood that the pressing portion 211 of the unlocking structure 21 is partially exposed on the surface of the upper side wall 121 or the lower side wall 122 of the charging body 1, and the specific location of the pressing portion 211 on the surface of the side wall 12 can be adjusted according to actual needs.

[0056] In this embodiment, the pressing portion 211 is disposed on the surface of the upper side wall 121. When the user presses the pressing portion 211 exposed on the charging body 1, the pressing portion 211 cannot be pressed any further until the exposed surface of the pressing portion 211 is flush with the surface of the upper side wall 121. At this time, the linkage structure 22 located inside the charging body 1 abuts against the first connecting portion 212, and the other end of the linkage structure 22 abuts against the clamping portion 231.

[0057] like Figure 7 As shown, the clamping portion 231 includes a first clamping end 2311 and a second clamping end 2312, and the first clamping end 2311 and the second clamping end 2312 are connected by a hub end 2313; the two ends of the hub end 2313 are respectively connected to the interior of the charging body 1; the first clamping end 2311 is exposed from the side of the charging body 1 and extends to the top 11 of the charging body 1, and is closed and connected to the top 11 of the charging body 1; the second clamping end 2312 is arranged inside the charging body 1.

[0058] like Figure 7As shown, the hub end 2312 includes an axial hole 2313A and a bearing 2313B, and the two ends of the bearing 2313B are respectively fixedly connected to the inside of the charging body 1, and the first clamping end 2311 and the second clamping end 2312 can rotate around the hub end 2313, and the movement directions of the first clamping end 2311 and the second clamping end 2312 are opposite.

[0059] Combination Figures 8 to 9 It can be known that, specifically during use, when the pressing portion 211 is pressed by external force, the first connecting portion 212 pushes the linkage structure 22 to squeeze it toward the clamping portion 231, so that the clamping portion 231 opens from the closed connection to the left side wall 123 or the right side wall 124 of the charging body 1. At this time, the reset structure 24 is in a tense connection state squeezed by the second clamping end 2312. However, when the pressing force on the pressing portion 211 is removed, the tense connection state of the reset structure 24 is restored to a loose connection state, and the second clamping end 2312 is pushed back to the original position by the reset structure 24. At this time, the first clamping end 2311 squeezes the linkage structure 22 driven by the second clamping end 2312, so that the clamping portion 231 returns from position D to position C. When the clamping portion 231 returns to position C, the clamping portion 231 also pushes the linkage structure 22 to move in the direction of C during the movement, and at this time, the linkage structure 22 pushes the first connecting portion 212, so that the pressing portion 211 connected to the first connecting portion 212 moves toward the outside of the charging body 1, so that the pressing portion 211 returns to its initial position. Fig. 9 As shown, part of the pressing portion 211 protrudes out from the outer surface of the charging body 1 .

[0060] In some other embodiments, the clamping portion 231 is provided in plurality, depending on the actual situation to facilitate the assembly of external devices.

[0061] Further, Fig. 9 As shown, the linkage structure 22 includes a transmission member 221, one end of the transmission member 221 has a first inclined surface 2211, and the other end opposite to the first inclined surface 2211 has a curved surface 2212; the first inclined surface 2211 is connected to the first connecting portion 212; the curved surface 2212 is connected to the clamping portion 231.

[0062] In this embodiment, the first connecting portion 212 has a second inclined surface 2121 matching the first top inclined surface 2211, and the second inclined surface 2121 is parallel to and overlaps with the first inclined surface 2212; the first inclined surface 2212 and the second inclined surface 2121 slide relative to each other at the overlapping contact point.

[0063] like Figures 9 and 10 As shown, when the pressing portion 211 is pressed, the first connecting portion 212 is driven by the pressing portion 211, and the first inclined surface 2211 and the second inclined surface 2121 slide relative to each other in opposite directions. As the pressing portion 211 is pressed deeper, the second inclined surface 2121 moves toward the larger end of the first inclined surface 2211, that is, moves from position A to position B. When the larger ends of the second inclined surface 2121 and the first inclined surface 2211 are aligned, that is, at position B, the clamping portion 231 is pushed out by the curved surface 2212 to change from a closed state to an open state on the charging body 11. Figure 8 As shown, the clamping portion 231 always moves in accordance with the curved surface 2212 during the opening process. Figure 8 As shown, the clamping portion 231 changes from a final contact point to a contact line on the curved surface 2212, that is, the clamping portion 231 moves from a point to a line on the curved surface.

[0064] When the clamping portion 231 is closed on the charging body 1 , the clamping portion 231 is in point contact with the curved surface 2212 . When the clamping portion 231 is in line contact with the curved surface 2212 , the clamping portion 231 is in an open state on the charging body 1 .

[0065] It should be noted that, during the closing and opening process of the clamping portion 231 , the transmission member 221 always maintains connection and contact with the first connecting portion 212 and the clamping portion 231 , respectively.

[0066] This helps to ensure that the clamping portion 231 can effectively close or open during the closing and opening process, avoiding invalid connection between the unlocking structure 21 and the locking structure 23, thereby preventing the clamping portion 231 from being effectively closed or opened, or causing the clamping portion 231 to be unstable when clamping an external device.

[0067] In some other embodiments, the transmission member 221 may be integrally provided with the clamping portion 231 to simplify the process steps in the production process.

[0068] Further Figures 8 to 10As shown, during the closing and opening process of the clamping portion 231, the resetting structure 24 disposed opposite to and connected to the second clamping end 2312 also produces corresponding expansion or contraction changes at the same time.

[0069] Specific as Figure 10 to Figure 11 As shown, the reset structure 24 includes an elastic component 241; one end of the elastic component 241 is connected to the interior of the charging body 1, that is, connected to the storage chamber 18, and the storage chamber 18 is provided with an assembly portion 181 near the top 11, and the assembly portion 181 has a first card slot 1811 and a second card slot 1812, the first card slot 1811 is used to assemble the transmission member 221 described above, and the second card slot 1812 is used to assemble the elastic component 241, the elastic component 241 is clamped in the second card slot 1812, and the other end of the elastic component 241 is connected and contacted with the clamping portion 231. Due to the elastic performance of the elastic component 241 itself, the connection between the elastic component 241 and the clamping portion 231 includes two states of loose connection and tight connection; the tight connection state of the elastic component 241 corresponds to the clamping portion 231 being in an open state; the loose connection state of the elastic component 241 corresponds to the clamping portion 231 being in a closed state.

[0070] like Fig.12 As shown, an elastic sheet 3 is provided at the connection between the charging body 1 and the external device; one side of the elastic sheet 3 is detachably connected to the charging body 1 , and a part of the other side of the elastic sheet 3 is in contact with the clamping portion 231 .

[0071] It should be understood that the elastic sheet 3 is made of a material with elastic properties. When the external device is placed on the surface of the top 11, the clamping portion 231 clamps the bottom end of the external device, giving the external device a force to squeeze the elastic sheet 3. Due to its own elastic properties, the elastic sheet 3 will generate a reaction force to squeeze the bottom of the external device. The two forces in different directions squeeze each other, so that the external device is firmly assembled on the top 11 and is not prone to shaking.

[0072] In order to further prevent the device from shaking during use, the elastic sheet 3 has a plurality of protrusions 31 ; when the plurality of protrusions 31 are squeezed, they will produce elastic deformation to produce counter-extrusion on the surface of the squeezed object.

[0073] It should be understood that the protrusion 31 can further increase the reaction force of the squeeze, so that the external device generates a greater squeezing force toward the surface of the elastic sheet 3, thereby further preventing the external device from shaking during use after being assembled on the top 11, thereby affecting the shooting effect.

[0074] A pan / tilt device includes a charger as described above. A charger of the present technical solution has a locking device 2, which can change the clamping portion 231 from a closed state to an open state by pressing a button to prepare for clamping an external device. After the external device is placed, the clamping portion 231 is restored to a closed state by removing the force on the pressing portion 211 to clamp the external device.

[0075] A pan-tilt device using the technical solution is suitable for various scenarios such as live broadcasting and recording short videos. In order to make the pan-tilt device more convenient in actual use, in some actual application scenarios, the pan-tilt device can also stand on a desktop.

[0076] Specifically, an assembly hole 182 is further provided at the bottom of the storage cavity 18, and the assembly hole 182 is used to install a tripod bracket 4 (not shown in the figure). The tripod bracket 4 (not shown in the figure) has two working modes: storage and expansion. When the pan-tilt device needs to be stood up, the tripod bracket needs to be opened to present a tripod manner, so that the pan-tilt device can stand on the desktop. When the standing function is not needed, the tripod bracket 4 needs to be stored.

[0077] According to the disclosure and teaching of the above description, the technical personnel in the field to which the utility model belongs can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
