DETAILED DESCRIPTION

[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] In recent years, the technology of unmanned aerial vehicles has been greatly improved, and many intelligent and multifunctional unmanned aerial vehicles have emerged. Most of these unmanned aerial vehicles use remote control to adjust the flight attitude. The battery life of the remote control is very important and directly affects the safety of the aircraft operation.

[0039] In the related art, the remote control uses a built-in battery and is fixed with a battery compartment cover, so that the battery cannot be replaced quickly; and when the battery compartment cover is not used, the firmness of the battery installation cannot be guaranteed, and it is easy to loosen or even fall off, which is inconvenient to use and seriously affects work efficiency.

[0040] The locking device provided by the exemplary embodiment of the utility model can be slidably arranged on the base through a locking piece, and can be restored to the initial position through a restoring structure. The object to be engaged, such as a battery, can be fixed on the base through the buckle of the locking piece, so that the battery can be installed firmly even without a battery compartment cover, and the disassembly and assembly of the battery is also more convenient and quick.

[0041] It should be noted that the locking device of the present invention can be used not only for installing batteries in remote controllers, but also for other devices that require battery installation, and is also applicable to any other locking structures that require convenient disassembly.

[0042] Figure 1 It is a schematic diagram of the three-dimensional exploded structure of the lower housing of the remote controller according to the embodiment of the utility model; Figure 4 yes Figure 1 A magnified schematic diagram of part A; Figure 2 Schematic diagram of the isometric structure of the locking member according to the embodiment of the utility model. Figure 1 , Figure 2 as well as Figure 4 As shown, the locking device provided by the exemplary embodiment of the utility model includes a base 20 and a locking member 10 slidably arranged on the base 20; the locking member 10 is provided with at least one group of buckles 11, and the base 20 has at least one group of first slide grooves 24 cooperating with the buckles 11, each buckle 11 passes through the base 20 through the corresponding first slide groove 24, and a part of the buckle 11 is located on the side of the base 20 away from the locking member 10; the locking member 10 has at least one second slide groove 12, and the base 20 is provided with at least one slide column 22 cooperating with the second slide groove 12, and the locking member 10 is connected to the base 20 through the slide column 22; the locking device also includes at least one recovery structure, and the recovery structure is used for the buckle 11 to return to the position and engage with the object to be engaged.

[0043] In actual applications, at least one sliding column 22 is provided on the base 20, and at least one second sliding groove 12 is provided on the locking member 10. The sliding column 22 penetrates the locking member 10 through the corresponding second sliding groove 12, thereby connecting the locking member 10 with the base 20. When the locking member 10 slides on the base 20, the sliding column 22 does not cause any obstacle, that is, the second sliding groove 12 is similar to an avoidance groove, so that when the locking member 10 slides relative to the base 20, it is not hindered by the sliding column 22, but the locking member 10 can be connected to the base 20 through the sliding column 22. The lock member 10 is provided with at least one group of buckles 11, each group of buckles 11 has two buckles 11, and the buckles 11 extend through the corresponding first slide grooves 24 of the base 20 to the other side of the base 20, that is, the engaging parts of the lock member 10 and the buckles 11 are respectively located on both sides of the base 20, and when the buckles 11 engage with the object to be engaged, the object to be engaged will be fixed on the base 20, with high firmness. It should be understood that in order to allow the lock member 10 to slide relative to the base 20, the buckles 11 will also slide in the first slide grooves 24, or in other words, the dimension of the extension direction of the first slide grooves 24 is greater than the dimension of the buckles 11. It should be noted that the extension direction of the second slide grooves 12 is consistent with the extension direction of the first slide grooves 24.

[0044] For example, when the object to be engaged pushes the buckle 11, the buckle 11 drives the lock member 10 to overcome the resistance of the recovery structure and slide relative to the base 20. After sliding to the preset position, the buckle 11 will be separated from the pushed part of the object to be engaged, and the recovery force of the recovery structure causes the lock member 10 to return to the initial position. At this time, the buckle 11 returns to the engagement part of the object to be engaged, and the two form an engagement connection and lock. Based on this, the object to be engaged can be installed by pushing, and the firmness of the buckle connection is higher than that of the prior art. Therefore, there is no need to set a hatch to assist in fixing the object to be engaged, so that the object to be engaged that originally needs to be built-in can be placed externally, and the disassembly and assembly convenience is higher.

[0045] Exemplarily, the object to be engaged may be a component that needs to be replaced frequently, such as a battery.

[0046] Figure 3 FIG. 2 is another isometric structural diagram of a locking member according to an embodiment of the present utility model. Figure 2-Figure 4 As shown, Figure 3 and Figure 2 The structure of the front and back sides of the locking member 10 is shown, and the restoring structure includes a first limiting portion 21, a second limiting portion 131, and an elastic member 31 whose two ends respectively stop at the first limiting portion 21 and the second limiting portion 131; the first limiting portion 21 is arranged on the surface of the base 20 facing the locking member 10; the locking member 10 also has a receiving groove 13 for accommodating at least a part of the elastic member 31, the second limiting portion 131 is arranged at one end of the receiving groove 13, and the first limiting portion 21 is located in the receiving groove 13 and close to the other end.

[0047] Exemplarily, the first limiting portion 21 in each return structure is a baffle protruding from the base 20, and the second limiting portion 131 is a positioning column at one end of the receiving groove 13. In fact, the first limiting portion 21 is located in the receiving groove 13 and is opposite to the second limiting portion 131, and one end of the elastic member 31, such as a spring, stops on the first limiting portion 21, and the other end is connected to the second limiting portion 131, or in other words, one end of the spring is sleeved on the second limiting portion 131, which is conducive to the fixation of the spring. Therefore, when the battery pushes the buckle 11, the lock member 10 will compress the spring, and the receiving groove 13 will slide along the first limiting portion 21. After reaching the preset position, the part of the battery that pushes the buckle 11 is separated from the buckle 11, and the spring is compressed and stretched, thereby driving the lock member 10 to return to the initial position until the buckle 11 is engaged with the battery.

[0048] Exemplarily, the number of the restoring structures is two, that is, there are two first limiting portions 21 on the base 20, and the number of the accommodating grooves 13, the number of springs, and the number of second limiting portions 131 on the locking member 10 are all two, so that the pushing, sliding process and the restoring process of the locking member 10 are more stable.

[0049] Exemplarily, two grooves may be provided on the base 20 at positions opposite to the two receiving grooves 13 , with most of the spring located in the receiving grooves 13 and the remaining portion located in the grooves of the base 20 to limit the spring.

[0050] It can be understood that the extension direction of the accommodating groove 13 is consistent with the sliding direction of the locking member 10. For the convenience of description, the sliding direction of the locking member 10 will be referred to as the second direction below, and the first direction perpendicular to the second direction refers to: the distribution direction from one accommodating groove 13 to another accommodating groove 13.

[0051] Figure 5 is a schematic diagram of the axonometric structure of a remote controller according to an embodiment of the utility model; Figure 6 yes Figure 5 A magnified view of part B. Figure 1 , Figure 5 and Figure 6 As shown, the locking device further includes a button portion 40 connected to one end of the locking member 10 , and the button portion 40 is used to push the locking member 10 to slide on the base 20 .

[0052] For example, when the battery needs to be removed from the base 20, that is, the battery needs to be separated from the buckle 11, the lock member 10 needs to be slid to a preset position, that is, the return position of the lock member 10, before the battery can be removed from the buckle 11. When the button portion 40 is pressed, the button portion 40 will drive the lock member 10 to overcome the elastic force of the spring and slide to the preset position before the battery can be removed.

[0053] like Figure 2 As shown, the button portion 40 may have two grooves, and two connecting blocks 41 are provided near the edge of the locking member 10 , and the two grooves on the button portion 40 cooperate with the two connecting blocks 41 to form an effective connection.

[0054] It should be noted that the button part 40 not only needs to be pressed when removing the battery, but also can be pressed to slide the locking part 10 to a preset position when installing the battery, so that the battery can be installed without the battery squeezing the buckle 11. After releasing the button part 40, the buckle 11 will automatically return to its initial position under the restoring force of the compression spring, thereby forming a buckle connection with the locking part of the battery.

[0055] like Figure 4 As shown, each group of first slide grooves 24 includes two first slide grooves 24, and the two first slide grooves 24 are respectively located near two opposite sides of the base 20. That is, two first slide grooves 24 in the same group are distributed along the first direction.

[0056] For example, Figure 5 and Figure 6As shown, for the stability of the battery after installation, the base 20 has three groups of first slide grooves 24, and each group of first slide grooves 24 corresponds to a group of clips 11, that is, the base 20 has 6 first slide grooves 24, and the clips 11 also have 6. The two sides of the base 20 here refer to the two sides opposite to each other along the first direction.

[0057] In order to connect the locking member 10 to the base 20 and prevent it from falling off during the sliding process, Figure 1 As shown, the sliding column 22 includes a cylindrical portion and a flange portion 23 located at the end of the cylindrical portion away from the base 20 . In the first direction, the size of the flange portion 23 is larger than the size of the second sliding groove 12 .

[0058] For example, the columnar portion can be a fixed column with a screw hole, and the flange portion 23 can be a thumb screw. When the two are screwed together, a sliding column 22 is formed. The second sliding groove 12 can be a long strip hole or an oblong hole. The diameter of the flange portion 23 is greater than the width of the second sliding groove 12. Based on this, the locking member 10 can slide along the sliding column 22, but cannot be separated from the sliding column 22, that is, the locking member 10 can be slidably connected to the base 20 without being separated, so as to maintain stability during the movement process.

[0059] In order to strengthen the stable connection between the locking member 10 and the base 20, the number of the sliding column 22 and the number of the second sliding groove 12 can be four, such as Figure 3 and Figure 4 Two second slide grooves 12 are located near one side of the locking member 10 and are spaced apart along the second direction, and another two second slide grooves 12 are located near the other side of the locking member 10 and are spaced apart along the second direction.

[0060] For example, when the outer contour of the locking member 10 is a rectangle, the four second sliding grooves 12 are respectively disposed near the four corners of the locking member 10. Correspondingly, the four sliding posts 22 are also located at the four corners of the base 20.

[0061] like Figure 2 As shown, in the locking device of the exemplary embodiment of the utility model, the buckle 11 has a first plate 111 and a second plate 112 connected to the end of the first plate 111 facing away from the locking member 10, and the second plate 112 and the first plate 111 are arranged in an L shape; the surface of the second plate 112 facing away from the first plate 111 has a first inclined surface 112a, and the first inclined surface 112a extends obliquely toward the locking member 10 along a direction away from the first plate 111.

[0062] Exemplarily, the first plate 111 is arranged on the surface of the locking member 10 perpendicular to the locking member 10, the second plate 112 is connected to the top end of the first plate 111 and extends toward the return direction of the locking member 10, and the first inclined surface 112a of the second plate 112 is inclined downward from the top surface of the second plate 112, that is, the thickness of the second plate 112 becomes smaller and smaller in the direction away from the first plate 111.

[0063] In order to make the buckle 11 and the battery easily engage with each other without misalignment, for example, Figure 2 As shown, the buckle 11 also has a third plate 113 connected to the first plate 111 and the second plate 112 respectively, and the first plate 111, the second plate 112 and the third plate 113 enclose a semi-enclosed snap-fitting space. The third plate 113 is closer to the side of the lock member 10 than the first plate 111, that is, the snap-fitting space has a notch on the inner side and on the side close to the end of the lock member 10 with the connecting block 41, so that the battery hook can be easily snapped into the snap-fitting space.

[0064] like Figure 5 As shown, an exemplary embodiment of the utility model also provides a remote control, including a shell, a battery and the locking device in the above embodiment, the base 20 is formed on the shell, the locking member 10 is located on the inner side of the shell, and parts of each buckle 11 are located on the outer side of the shell; each hook 53 of the battery is engaged with the part of the corresponding buckle 11 located on the outer side of the shell.

[0065] Figure 7 Schematic diagram of the battery isometric structure according to the embodiment of the present utility model. Figure 7 As shown, the battery has at least one group of recessed portions, each group of recessed portions includes two recessed portions, each recessed portion has a first opening 51 formed on the bottom surface of the battery, and a second opening 52 formed on the side surface of the battery; the battery also has at least one group of hooks 53, each hook 53 is formed on two adjacent side walls of the corresponding recessed portion, the hook 53 has a second inclined surface 531, and the hook 53 is adapted to the buckle 11.

[0066] For example, the battery has six recessed portions, which respectively match the six clips 11 of the locking member 10. Specifically, the recessed portion forms a first opening 51 and a second opening 52 on the bottom surface of the battery to allow the second plate 112 to enter the interior of the recessed portion. At the same time, the hook 53 enters the locking space through the two notches on the clip 11, and then the clip 11 and the hook 53 form a limit to each other and are clipped together to form a self-locking fixation.

[0067] It should be noted that the battery can be conveniently installed by pressing downward from the top of the buckle 11, and the second inclined surface 531 provided on the hook 53 cooperates with the first inclined surface 112a of the buckle 11, so that the hook 53 can slide into the engaging space of the buckle 11 more easily during the extrusion process, and the second plate 112 of the buckle 11 slides into the space between the hook 53 and the bottom wall of the recessed portion. It should be noted that the second inclined surface 531 provided on the hook 53 can also be a straight surface.

[0068] like Figure 7 As shown, the recessed portion has four walls, of which the bottom wall is parallel to the bottom surface of the battery, and the three side walls are perpendicular to the bottom surface of the battery, wherein the hook 53 is formed on two adjacent side walls, and the first opening 51 is formed between the second inclined surface 531 and the other side surface.

[0069] It should be noted that if Figure 5 As shown, a connector male seat is also provided at the end position of the base 20 away from the locking member 10 and close to the button portion 40, and as shown in FIG. Figure 7 The battery shown is also provided with a connector at its end, so that after the battery hook 53 and the buckle 11 are self-lockingly fixed, the battery connector can be connected to the connector male socket to form an electrical connection to supply power to the remote control.

[0070] When the battery runs out of power, pressing the button portion 40 will drive the locking member 10 to move forward relative to the base 20 and compress the spring at the same time. At this time, the battery hook 53 is separated from the buckle 11 of the locking member 10. The battery is taken out upward by hand, and the button portion 40 is released to compress the spring to return to its original position, thereby realizing rapid battery replacement and improving work efficiency.

[0071] Exemplarily, the remote controller includes a housing formed by assembling an upper housing and a lower housing, and the housing can accommodate components such as a locking member and a circuit board. A base 20 is formed in the middle of the upper housing, that is, the base 20 is a part of the upper housing, and an indented groove is formed on the outer side of the upper housing at the position of the base 20, and six buckles 11 extend from the inner side of the upper housing to the indented grooves on the outer side of the upper housing, and the size and dimensions of the grooves can allow the battery to enter to form a circumferential fixation of the battery. When each hook 53 of the battery is engaged with the buckle 11 of the locking member 10, the hook 53 and the buckle 11 will not be disengaged without pressing the button part 40. Based on this, the battery is exposed on the outer side of the remote control housing, and the battery is connected to the outside of the housing by a snap connection. Even if the cover is not used for auxiliary fixation, the battery is not prone to the risk of loosening and falling.

[0072] An exemplary embodiment of the present utility model further provides a drone assembly, including a drone and the remote controller in the above embodiment, wherein the remote controller is communicatively connected with the drone.

[0073] Compared with the prior art, the advantages of the remote controller and drone assembly of the exemplary embodiment of the utility model are the same as those of the above-mentioned locking device, which will not be repeated here.

[0074] Those skilled in the art should understand that the above embodiments are only for the purpose of clearly illustrating the present invention, and are not intended to limit the scope of the present invention. For those skilled in the art, other changes or modifications may be made based on the above disclosure, and these changes or modifications are still within the scope of the present invention.
