[0008] The limiting assembly includes a limiting member and an elastic member.

[0044] The embodiments of this application are introduced below in conjunction with the drawings in the specification:

[0045] Reference Figures 1 to 7, A quick-release device according to an embodiment of the present application is used to achieve quick disassembly and assembly between a camera module and a drone. The quick-release device includes a first connector 100, a limiting component 300, and a second connector 200. The first connector 100 is used to connect to the drone body 500, and the second connector 200 is used to connect to the camera module. Thus, through the quick release between the first connector 100 and the second connector 200, the quick release between the drone body 500 and the camera module can be achieved. The first connector 100 is provided with an installation groove 110. The installation groove 110 is provided with an opening facing the first direction. The installation groove 110 further includes a first bottom wall 111 perpendicular to the first direction, and two opposite first side walls 112. The second direction is perpendicular to the two first side walls 112, and both first side walls 112 are convexly provided with first protrusions 113 extending in the second direction. The limiting component 300 includes a limiting member 310 and an elastic member 320. Along the first direction, one end of the elastic member 320 abuts against the first connector 100, and the other end of the elastic member 320 abuts against the limiting member 310. The end of the limiting member 310 facing away from the elastic member 320 extends into the installation groove 110, and the limiting member 310 is movably connected to the first connector 100. The second connector 200 includes two opposite second side walls 210. The second side walls 210 can have an angle or be parallel to the first side walls 112. Both second side walls 210 are convexly provided with second protrusions 220 extending in the second direction.

[0046] The second connector 200 is configured to enter the installation groove 110 from the opening and abut against the limiting member 310 at a first position, so that the limiting member 310 further compresses the elastic member 320 along the first direction. Thus, the limiting member 310 is driven to be substantially flush with the groove wall of the installation groove 110, for avoiding the movement of the second connector 200 relative to the first connector 100 along a third direction. And when the second connector 200 moves to a second position along the third direction, each second protrusion 220 correspondingly abuts against one side of each first protrusion 113 facing the first bottom wall 111. The first protrusion 113 is used to carry the second protrusion 220. Thus, the first protrusion 113 cooperates with the first bottom wall 111 to limit the movement of the second connector 200 along the first direction. And at the second position, the second connector 200 is separated from the limiting member 310, and the elastic member 320 rebounds and resets along the first direction, driving the limiting member 310 to move relative to the first connector 100 along the first direction until a part of the limiting member 310 is placed in the installation groove 110, for limiting the movement of the second connector 200 along the third direction from the second position to the first position.

[0047] During the process of the second connector 200 moving from the first position to the second position, along the second direction, the two first side walls 112 abut against the second protrusion 220 to provide guidance for the second connector 200, and at the second position, the two first side walls 112 restrict the second connector 200 from moving along the second direction. Thus, at the second position, the movement of the second connector 200 along the first direction, the second direction, and the third direction is restricted, realizing the connection between the first connector 100 and the second connector 200. Compared with the connection methods such as screws, the quick-release device in the present application does not require additional tools and is more flexible and convenient to connect.

[0048] Among them, the first direction, the second direction, and the third direction are perpendicular to each other pairwise.

[0049] In addition, when the first connector 100 and the second connector 200 need to be separated, the limiting member 310 is driven to further compress the elastic member 320 along the first direction until the limiting member 310 disengages from the installation groove 110, releasing the restriction on the movement of the second connector 200 along the third direction. The second connector 200 is driven to move from the second position to the first position along the third direction. At the first position, the first protrusion 113 is separated from the second protrusion 220, further releasing the restriction on the movement of the second connector 200 along the first direction, so that the second connector 200 can move out of the installation groove 110 along the first direction (while separating, the first side wall 112 is separated from the second protrusion 220, releasing the restriction on the movement of the first connector 100 along the second direction), thereby realizing the disassembly and separation of the first connector 100 and the second connector 200, which is beneficial to improving the disassembly and assembly efficiency.

[0050] It should be noted that the first connector 100 can be fixed to the drone body 500 by connection methods such as screws and buckles. Similarly, the second connector 200 and the camera module can also be fixed by screws and buckles.

[0051] Reference Figures 2 to 7In some embodiments, the first connecting member 100 includes a first limiting wall 114 perpendicular to the third direction, and the second connecting member 200 includes a second limiting wall 230 perpendicular to the third direction. The first limiting wall 114 is provided with a plug-in groove 1141 extending along the third direction, and the second limiting wall 230 is provided with a plug-in portion 231 extending along the third direction. In the second position, the first limiting wall 114 abuts against the second limiting wall 230, and the plug-in portion 231 is located in the plug-in groove 1141. The plug-in portion 231 is used to electrically connect the transmission end of the camera module, and the plug-in groove 1141 is used to accommodate the transmission interface of the drone. Therefore, when the first connector 100 and the second connector 200 are assembled, the communication connection between the camera module and the drone can be achieved at the same time, and when the first connector 100 and the second connector 200 are disassembled, the communication disconnection between the camera module and the drone can be achieved at the same time, so that the physical disassembly and assembly and the communication on and off are achieved at the same time, eliminating the additional steps of disconnecting or connecting the transmission wires, which is beneficial to further improve the disassembly and assembly efficiency between the drone and the camera module.

[0052] Specifically, when the second connecting member 200 moves from the opening along the first direction to the first position in the installation groove 110, the plug-in portion 231 is projected into the plug-in slot 1141 along the third direction, and along the third direction, the plug-in portion 231 is located on the side of the second limiting wall 230 facing the first limiting wall 114. When the second connecting member 200 moves from the first position to the second position along the third direction in the installation groove 110, the plug-in portion 231 gradually approaches the plug-in slot 1141 until the second connecting member 200 moves to the second position, and the plug-in portion 231 is inserted into the plug-in slot 1141. Thus, in the second position, the first connecting member 100 is connected to the second connecting member 200, and the drone is electrically connected to the camera module.

[0053] Similarly, when the camera module needs to be disassembled and replaced, the limit member 310 is driven to further compress the elastic member 320 along the first direction, thereby releasing the restriction on the movement of the second connecting member 200 along the third direction. The second connecting member 200 moves from the second position to the first position along the third direction, and the plug-in portion 231 gradually disengages from the plug-in slot 1141, which can not only realize the separation of the first connecting member 100 and the second connecting member 200, but also disconnect the electrical connection between the drone and the camera module at the same time, further improving the disassembly and assembly efficiency between the drone and the camera module, which is beneficial to shortening the time for replacing the camera module.

[0054] It should be noted that the plug-in portion 231 may be a Type C male connector, and the plug-in slot 1141 may accommodate a Type C female connector connected to the drone.

[0055] refer to Figures 2 to 5In some embodiments, the two first side walls 112 are each provided with a plurality of first protrusions 113, and the two second side walls 210 are each provided with a plurality of second protrusions 220. Along the third direction, there is a first interval between two adjacent first protrusions 113 located on the same first side wall 112, and there is a second interval between two adjacent second protrusions 220 located on the same second side wall 210. The first interval is used to avoid the second protrusions 220 when the second connecting member 200 moves to the mounting groove 110 along the first direction, and the second interval is used to ensure that when the second connecting member 200 moves to the second position, the second protrusion 220 abuts against the side of the first protrusion 113 facing the first bottom wall 111, so that the plurality of first protrusions 113 bear the plurality of second protrusions 220 one by one. By providing the plurality of first protrusions 113 and the plurality of second protrusions 220, the stability of the connection between the first connecting member 100 and the second connecting member 200 can be improved, and the bearing capacity of the quick release device along the first direction can be increased.

[0056] Among them, along the third direction, the length of the first interval is greater than the length of any second protrusion 220, which is used to ensure that each second protrusion 220 can be staggered with two adjacent first protrusions 113 along the third direction, so that each second protrusion 220 can move along the first direction from the side of the first protrusion 113 away from the first bottom wall 111 to the side of the first protrusion 113 facing the first bottom wall 111. The length of the second interval is less than the maximum distance between any two adjacent first protrusions 113, which is used to ensure that at the second position, two adjacent second protrusions 220 can respectively and one-to-one contact with two adjacent first protrusions 113, so as to avoid the second protrusion 220 being suspended in the second position, which is beneficial to fully ensure the load-bearing capacity of the quick release device along the first direction. Compared with extending the extension length of the first protrusion 113 and the second protrusion 220 along the third direction, by setting a plurality of first protrusions 113 to cooperate with a plurality of second protrusions 220 and limiting the setting of the first interval and the second interval, it is possible to improve the load-bearing capacity of the quick-release device along the first direction while avoiding additionally extending the mounting groove 110 along the third direction to avoid the installation of the second connecting member 200, which is beneficial to reducing the volume of the quick-release device.

[0057] refer to Figures 1 to 7, in some embodiments, the limiting member 310 includes a connected limiting portion 311 and an unlocking portion 312. Along the first direction, both the limiting portion 311 and the unlocking portion 312 are movably connected to the first connecting member 100. The elastic member 320 abuts against at least one of the limiting portion 311 and the unlocking portion 312. A part of the limiting portion 311 extends into the installation groove 110 along the first direction. The unlocking portion 312 is located outside the installation groove 110 and protrudes outward from the outer surface of the first connecting member 100. When the second connecting member 200 is in the second position, the limiting portion 311 abuts against one side of the second connecting member 200 along the third direction, and the first limiting wall 114 abuts against the opposite side of the second connecting member 200 along the third direction. Through the cooperation of the limiting portion 311 and the first limiting wall 114, it is used to jointly limit the movement of the second connecting member 200 along the third direction. The unlocking portion 312 is driven to drive the limiting portion 311 to move synchronously relative to the first connecting member 100 along the first direction, and further compress the elastic member 320. The limiting portion 311 gradually exits the installation groove 110 under the drive of the unlocking portion 312, so as to release the movement restriction of the second connecting member 200 along the third direction. Thus, the disassembly and unlocking of the second connecting member 200 can be realized outside the installation groove 110 without driving the limiting portion 311 inside the installation groove 110, and the unlocking is more convenient and fast.

[0058] Reference Figures 1 to 7 , in some embodiments, along the first direction, one of the first connecting member 100 and the limiting member 310 is provided with a guiding portion 120, and the other is provided with a guiding hole 240. A part of the guiding portion 120 is located in the guiding hole 240. The elastic member 320 is sleeved on the outer peripheral wall of the guiding portion 120. The cooperation between the guiding portion 120 and the guiding hole 240 is used to guide the elastic member 320 to compress and rebound along the first direction, avoid the deflection of the elastic member 320, and make the reset of the limiting member 310 smoother.

[0059] Specifically, the elastic member 320 can be a spring, the guiding portion 120 can be a cylindrical structure extending along the first direction, and the guiding hole 240 can be a cylindrical hole. Taking the first connecting member 100 being provided with the guiding portion 120 and the limiting member 310 being provided with the guiding hole 240 as an example, the elastic member 320 is sleeved on the outer peripheral wall of the guiding portion 120 to limit the compression and rebound of the elastic member 320 along the first direction. A part of the guiding portion 120 is located in the guiding hole 240 to guide the relative movement of the limiting member 310 and the first connecting member 100 along the first direction. A part of the elastic member 320 can also be placed in the guiding hole 240 to avoid the end of the elastic member 320 from deflecting relative to the first direction when the limiting member 310 and the guiding portion 120 move away from each other. Thus, through the cooperation of the guiding portion 120 and the guiding hole 240, the smoothness of the disassembly and assembly of the quick-release device can be further improved.

[0060] Reference Figures 1 to 7In other embodiments, the limiting assembly 300 includes two elastic members 320, two guide portions 120 and two guide holes 240, wherein the unlocking portion 312 and the limiting portion 311 are both provided with guide holes 240, wherein one elastic member 320 is sleeved on the outer peripheral wall of one of the guide portions 120 and cooperates with one of the guide holes 240, and the other elastic member 320 is sleeved on the outer peripheral wall of the other guide portion 120 and cooperates with the other guide hole 240, thereby, the limiting assembly 300 unlocks the connection between the first connecting member 100 and the second connecting member 200 outside the mounting groove 110 more smoothly.

[0061] refer to Figures 1 to 7 In some embodiments, the first connecting member 100 is provided with a first guide wall 130, and the stopper 310 is provided with a second guide wall 250. In the first position, the first guide wall 130 and the second guide wall 250 gradually move away from the first bottom wall 111 along the first direction, and both the first guide wall 130 and the second guide wall 250 extend toward the second position. For example, the first guide wall 130 and the second guide wall 250 can be arranged in parallel. The first guide wall 130 is configured to abut against the second guide wall 250 when the second connecting member 200 is in the first position, and when the second connecting member 200 moves from the first position to the second position, the stopper 310 is driven to further compress the elastic member 320 along the first direction, thereby reducing the elastic resistance that needs to be overcome when the first connecting member 100 and the second connecting member 200 are assembled, which is beneficial to making the assembly more labor-saving.

[0062] It should be noted that the greater the compression of the elastic member 320, the greater the elastic force generated by the elastic member 320. As the second connecting member 200 moves from the first position to the second position, the elastic member 320 is gradually compressed, and the elastic force generated gradually increases. Compared with not setting a guide structure and directly compressing the elastic member 320 to the maximum compression amount, the setting of the first guide wall 130 and the second guide wall 250 makes the assembly between the first connecting member 100 and the second connecting member 200 more labor-saving.

[0063] refer to Figures 2 to 7 In some embodiments, the second connecting member 200 is provided with a positioning groove 260, and the second guide wall 250 extends from the bottom wall of the positioning groove 260 to the notch of the positioning groove 260. Along the third direction, the second guide wall 250 is located on the side of the positioning groove 260 away from the second protrusion 220. When the second connecting member 200 is in the first position, a portion of the limiting member 310 is located in the positioning groove 260. The positioning groove 260 is used to accommodate a portion of the limiting member 310, so as to facilitate the alignment and installation of the second connecting member 200 and the first connecting member 100 in the first position.
