[0039] like Figures 1 to 7 As shown, in one embodiment of the present invention, a drone battery fixing device is provided for fixing Figure 7The battery 30 shown, the drone battery fixing device, is used to fix the battery 30 with a locking groove 32, and includes a locking assembly 10 and a fixing frame 20 for connecting to the drone, the fixing frame 20 is provided with a mounting groove 21 for installing the battery 30, the fixing frame 20 is provided with a mounting surface 22, and the mounting surface 22 is provided with a through hole 221 connected to the mounting groove 21; the locking assembly 10 includes a locking member 11 and a button member 12, and the button member 12 and the locking member 11 are both arranged on the mounting surface 22; the locking member 11 includes a locking portion 111, the locking portion 111 is penetrated in the through hole 221 and is arranged toward the mounting groove 21, and the button member 12 is used to push the locking portion 111 to extend into or withdraw from the locking groove 32 so that the locking portion 111 is locked or disengaged from the battery 30.

[0040] Specifically, the battery 30 is arranged in the installation groove 21. When the through hole 221 and the locking groove 32 are arranged opposite to each other, the button member 12 drives the locking portion 111 of the locking member 11 to pass through the through hole 221 and move downward until it extends into the locking groove 32. The locking portion 111 can be abutted and locked with the battery 30, thereby firmly limiting the battery 30 in the installation groove 21, thereby achieving the locking and fixing of the battery 30. When the battery 30 needs to be removed, the button member 12 drives the locking portion 111 to move upward until it retracts into the through hole 221. The locking groove 32 is withdrawn from the hole 221. At this time, the locking portion 111 is separated from the battery 30, and the lock of the battery 30 is released, thereby facilitating the replacement of the battery 30. The drone battery fixing device of the present invention is simple and convenient for loading and unloading the battery 30, saving time and effort, and when the battery 30 is placed in the installation groove 21, the battery 30 is locked and fixed by the locking piece 11. The battery 30 is fixed with high reliability, effectively avoiding the battery 30 from detaching, ensuring the normal use of the battery 30, and is convenient and quick to use.

[0041] In another embodiment of the present invention, refer to Figure 6 As shown, the inner wall surface of the mounting groove 21 of the provided drone battery fixing device is provided with a limiting groove 261 that is compatible with the limiting protrusion 31 on the battery; and / or, the inner wall surface of the mounting groove 21 is provided with a limiting protrusion 31 that is compatible with the limiting groove 261 on the battery.

[0042] Specifically, when the battery 30 is placed in the mounting slot 21 , the limiting protrusion 31 is snapped into the limiting groove 261 , thereby achieving the upper and lower fixation of the battery 30 in the mounting slot 21 , and the fixation of the battery 30 in the mounting slot 21 is stable and reliable.

[0043] Further, see Figure 6As shown, the fixing frame 20 includes a top plate 25 and two side plates 26, the two side plates 26 are respectively vertically connected to the opposite sides of the top plate 25 and are both vertically arranged with the top plate 25 and are U-shaped, the top plate 25 and the two side plates 26 are jointly surrounded to form a mounting groove 21, and the upper top surface of the top plate 25 is used as the mounting surface 22. When in use, the battery 30 slides into or out of the mounting groove 21 between the two side plates 26, and the installation operation of the battery 30 is simple; in addition, when the opposite sides of the battery 30 are provided with limiting protrusions 31 or limiting grooves 261, the two opposite side surfaces of the two side plates 26 are provided with corresponding limiting grooves 261 and limiting protrusions 31, so that when the battery 30 is placed in the mounting groove 21, the limiting protrusion 31 is snapped into the limiting groove 261, thereby realizing the upper and lower fixation of the battery 30 in the mounting groove 21, and the fixation of the battery 30 in the mounting groove 21 is stable and reliable.

[0044] In another embodiment of the present invention, the locking member 11 of the provided drone battery fixing device also includes a locking protrusion connected to the locking portion 111, and a locking groove is provided on the surface of the button member 12 facing away from the mounting surface 22. When the locking portion 111 withdraws from the mounting groove 21, the locking protrusion is pressed against the surface of the button member 12 facing away from the mounting surface 22, and the locking protrusion is inserted into the locking groove when the locking portion 111 extends into the mounting groove 21.

[0045] Specifically, when the battery 30 needs to be locked, the locking protrusion is inserted into the locking groove. During this process, the locking protrusion moves downward, thereby driving the locking portion 111 connected thereto to move downward through the through hole 221 and extend into the mounting groove 21, thereby locking the battery 30; when the battery 30 needs to be unlocked, the locking protrusion is moved out of the locking groove. During this process, the locking protrusion drives the locking portion 111 to move upward, thereby exiting the mounting groove 21, and then disengaging from the battery 30, completing the unlocking of the battery 30. In this way, when the locking protrusion is inserted into the locking groove, the locking effect of the locking portion 111 is good, and the locking reliability of the battery 30 is good.

[0046] In another embodiment of the present invention, refer to Figure 2 and Figure 5 As shown, the locking protrusion of the provided drone battery fixing device is a wedge-shaped protrusion 113, and the locking groove is a wedge-shaped groove 121.

[0047] Specifically, during the unlocking process of the battery 30, the wedge-shaped protrusion 113 gradually withdraws from the wedge-shaped groove 121 along the inclined inner wall surface of the wedge-shaped groove 121, thereby realizing the unlocking of the battery 30. The unlocking operation of the battery 30 is simple and convenient, saving time and effort, and the replacement of the battery 30 is also more convenient and quick.

[0048] Optionally, combined Figure 6As shown, the cross section of the wedge-shaped protrusion 113 is in the shape of a right triangle, and the wedge-shaped protrusion 113 includes a first vertical surface 1131 and an inclined surface 1132, and the inclined surface 1132 extends downward toward the first vertical surface 1131 until it is connected to the first vertical surface 1131, so that the width of the wedge-shaped protrusion 113 becomes smaller from top to bottom; the cross section of the wedge-shaped groove 121 is similar to a right triangle shape, and the wedge-shaped groove 121 includes a second vertical surface 1211 and an arc surface 1212, and the arc surface 1212 extends downward toward the second vertical surface 1211 in an arc shape until it is connected to the second vertical surface 1211, and the opening width of the wedge-shaped groove 121 becomes larger as it goes up When the wedge-shaped protrusion 113 is completely inserted into the wedge-shaped groove 121, the first vertical surface 1131 abuts against the second vertical surface 1211, which can play a good limiting role, that is, the wedge-shaped protrusion 113 is difficult to move out of the wedge-shaped groove 121 from the side of the first vertical surface 1131, and the locking state of the locking portion 111 is more fixed, stable and reliable; and the inclined surface 1132 abuts against the arc surface 1212, and through the guiding effect of the inclined surface 1132 and the arc surface 1212, the wedge-shaped protrusion 113 can be easily slid out of the wedge-shaped groove 121 from the side of the inclined surface 1132, making the unlocking operation of the locking portion 111 more time-saving and labor-saving.

[0049] In another embodiment of the present invention, refer to Figure 1 , Figure 2 and Figure 3 As shown, the locking assembly 10 of the drone battery fixing device provided also includes a first elastic member 13, the two ends of which are respectively against the locking portion 111 and the fixing frame 20 and are used to press the locking protrusion against the locking groove. Specifically, when the locking groove on the button member 12 slides to the locking protrusion, the first elastic member 13 actively pushes the locking protrusion into the locking groove to achieve the fixed locking of the battery 30. At the same time, under the action of the first elastic member 13, the locking protrusion can be tightly stuck in the locking groove to avoid the locking protrusion from moving out of the locking groove due to vibration or force, prevent mis-locking, and greatly improve the reliability of the locking and fixing of the battery 30.

[0050] In another embodiment of the present invention, refer to Figure 5 and Figure 6As shown, the mounting surface 22 of the drone battery fixing device provided is provided with two long protrusions 222, the two long protrusions 222 are arranged in parallel and spaced apart, and the button member 12 is located between the two long protrusions 222 and slides along the length direction of the long protrusion 222 to drive the wedge-shaped groove 121 to engage or separate with the wedge-shaped protrusion 113. Specifically, the button member 12 is located between the two long protrusions 222, and the long protrusion 222 guides and restricts the button member 12, so that the button member 12 slides between the two long protrusions 222, so that the wedge-shaped groove 121 on the button member 12 can be accurately engaged or separated with the wedge-shaped protrusion 113 by only gently pushing the button member 12, and the operation is simple and convenient.

[0051] In another embodiment of the present invention, refer to Figure 3 , Figure 5 and Figure 6 As shown, the button member 12 of the drone battery fixing device provided is provided with a long hole 122 extending along the length direction of the long protrusion 222 , and the locking portion 111 is penetrated in the long hole 122 and the through hole 221 .

[0052] Specifically, the elongated hole 122 provides an avoidance space for the locking portion 111. After passing through the elongated hole 122, the locking portion 111 can be smoothly inserted into the through hole 221, thereby avoiding interference between the button member 12 and the movement of the locking portion 111. At the same time, the elongated hole 122 can also guide the up and down movement of the locking portion 111, so that the locking portion 111 can be accurately inserted into the through hole 221 to complete the locking of the battery 30; at the same time, the locking portion 111 is passed through the elongated hole 122 of the button member 12, and the button member 12 can be used as an installation base for the locking member 11 to support the locking member 11. In this way, the entire locking assembly 10 has a compact structure, a small size, and a good use effect.

[0053] Optionally, wedge-shaped grooves 121 are provided on both sides of the elongated hole 122, and the number of wedge-shaped protrusions 113 can be two, and the two wedge-shaped protrusions 113 are respectively located on both sides of the locking portion 111. In this way, when the locking portion 111 is inserted into the elongated hole 122, the two wedge-shaped protrusions 113 are respectively inserted into the two wedge-shaped grooves 121 or abut against the surface of the button member 12. Such multi-point support makes the movement of the locking portion 111 more stable and reliable, and the fixed locking effect of the battery 30 is better.

[0054] In another embodiment of the present invention, refer to Figure 4 and Figure 5As shown, the locking assembly 10 of the provided drone battery fixing device also includes a second elastic member 14, and the fixing frame 20 also includes a first abutment plate 23 and a second abutment plate 24 arranged on the mounting surface 22, the first abutment plate 23 and the second abutment plate 24 are arranged at intervals, the second elastic member 14 and the button member 12 are both located between the first abutment plate 23 and the second abutment plate 24, the two ends of the second elastic member 14 respectively abut against the button member 12 and the first abutment plate 23, and the second elastic member 14 is used to press the button member 12 against the second abutment plate 24.

[0055] Specifically, after the button member 12 is pushed to slide on the mounting plate 28, the button member 12 can be automatically reset under the elastic action of the second elastic force, making the operation of the button member 12 easier; then in the specific use process, when the second elastic member 14 presses the button member 12 against the second abutment plate 24, the wedge-shaped protrusion 113 can be set to a position that is inserted into the wedge-shaped groove 121. Since the button member 12 is subjected to the abutment force of the second elastic member 14, the button member 12 will not slide at will due to the force, thereby improving the reliability of the locking and fixation of the battery 30. Of course, in other embodiments, when the second elastic member 14 presses the button member 12 against the second abutment plate 24, the wedge-shaped protrusion 113 and the wedge-shaped groove 121 can be staggered, so that the locking portion 111 and the battery 30 are in a separated and unlocked state, which is also convenient for the installation and removal of the battery 30. The specific usage setting can be selected according to actual conditions.

[0056] In another embodiment of the present invention, refer to Figure 2 and Figure 6 As shown, the button member 12 of the drone battery fixing device is provided with a button portion 123, and the second abutting plate 24 is provided with a button hole 241, and the button portion 123 passes through the button hole 241 and protrudes out of the second abutting plate 24. In this way, the button member 12 can slide by simply pressing the button portion 123, thereby achieving locking and unlocking of the battery 30, and the operation is more convenient and quick.

[0057] Optionally, when the second elastic member 14 presses the button member 12 against the abutment plate, the wedge-shaped protrusion 113 is set to a position where it is inserted into the wedge-shaped groove 121, and the second vertical surface 1211 is closer to the second elastic member 14 than the arc surface 1212, so that the elastic force of the second elastic member 14 will push the second vertical surface 1211 to tightly abut against the second vertical surface 1211, making it difficult for the wedge-shaped protrusion 113 to escape from the wedge-shaped groove 121, thereby making the locking portion 111 lock the battery 30 with better stability and reliability. When the battery 30 needs to be locked, it is only necessary to release the button part 123. Under the elastic force of the second elastic member 14 and the elastic force of the first elastic member 13, the button member 12 can be automatically reset, so that the wedge-shaped protrusion 113 and the wedge-shaped groove 121 automatically return to the engaging position, ensuring that the battery 30 loaded in the mounting slot 21 is always stably locked by the locking part 111, and the battery 30 is fixed stably and reliably. In this way, the operation of the drone battery fixing device only requires pressing the button member 12 to unlock, and its operation is more convenient and quick, saving time and effort.

[0058] Preferably, the first elastic member 13 and the second elastic member 14 are both springs.

[0059] In another embodiment of the present invention, refer to Figure 2 , Figure 3 and Figure 5 As shown, the locking member 11 of the provided drone battery fixing device also includes a guide portion 112, which is connected to the locking portion 111. The fixing frame 20 is provided with a guide groove 271 extending along the axial direction of the through hole 221, and the guide portion 112 is located in the guide groove 271. Specifically, the locking portion 111 moves up and down in the through hole 221, and the guide portion 112 also moves up and down in the guide groove 271. The guide groove 271 can provide a good guiding effect on the guide portion 112, so that the locking portion 111 can accurately pass through the through hole 221 and extend into the installation groove 21 to lock the battery 30, or the locking portion 111 can accurately move up from the through hole 221 and withdraw from the installation groove 21 to disengage from the battery 30, and the unlocking is completed. The movement of the locking portion 111 is stable and accurate, and the locking reliability of the battery 30 is better.

[0060] Optionally, a wedge-shaped protrusion 113 is provided on the guide portion 112 and protrudes toward the surface of the mounting surface 22, so that the wedge-shaped protrusion 113 can move up and down, thereby driving the guide portion 112 and the locking portion 111 connected to the guide portion 112 to move up and down, thereby realizing the locking and unlocking of the battery 30. The guide portion 112, the locking portion 111 and the wedge-shaped protrusion 113 are integrally formed, so that the entire locking member 11 has good structural strength, ensuring that the locking member 11 can firmly lock the battery 30.

[0061] Furthermore, combined with Figure 5 and Figure 6As shown, the fixing frame 20 also includes a mounting plate 28, which is connected to the upper part of the second abutment plate 24 and is horizontally spaced apart from the top plate 25, the button member 12 and the locking member 11 are located between the mounting plate 28 and the top plate 25, the mounting plate 28 is provided with a guide plate 27, the guide plate 27 is arranged perpendicular to the mounting plate 28, and a guide groove 271 is arranged on the guide plate 27, wherein the number of the guide plates 27 can be two, and the two guide portions 112 are respectively inserted into the guide grooves 271 of the two guide plates 27, so that the movement of the locking member 11 is more stable and reliable, and the function of the locking member 11 can also be supported, and the mounting plate 28 is also used to connect with the fuselage of the drone; the first abutment plate 23, the mounting plate 28, the second abutment plate 24, the top plate 25 and the side plate 26 are integrally formed, so that the fixing frame 20 has a simple structure, is easy to manufacture, has good structural strength, and the fixation of the battery 30 is also more stable and reliable.
