Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a battery assembly and a UAV. Background Technology

[0002] Drones are widely used in agriculture, exploration, photography, border patrol and other fields due to their advantages of maneuverability, rapid response, unmanned flight and low operation requirements.

[0003] Drones typically have removable batteries. Currently, the batteries are often connected to the drone body via a flip-type snap-fit ​​structure. This flip-type snap-fit ​​structure is complex to assemble, takes up a lot of space, and requires the robotic arm gripper to flip to press the snap-fit ​​structure and remove the battery from the drone. This is inconvenient, and current technology cannot detect whether the battery is properly installed. Utility Model Content

[0004] The purpose of this application is to provide a battery assembly and a drone, so as to simplify the structure of the drone battery assembly and simplify the process of installing and removing the battery assembly. The specific technical solution is as follows:

[0005] An embodiment of the first aspect of this application provides a battery assembly for use in a drone. The battery assembly includes: a battery and a snap-fit ​​structure, wherein the battery is detachably connected to the battery mounting cavity of the drone via the snap-fit ​​structure; the battery includes a housing having an opening; the snap-fit ​​structure includes a base, a button, a reset member, a limiting device, and a detection device; the base is fixedly connected to the opening of the housing; the detection device and the limiting device are respectively fixedly connected to the base; the button is slidably connected to the base along a first direction; one end of the reset member is connected to the base, and the other end is connected to the button.

[0006] In some embodiments, when no external force is applied to the button, and the button abuts against the limiting device under the action of the reset member, the button is in a first position, and the button is not in contact with the detection device, allowing the battery assembly to be installed in the battery mounting cavity of the drone. When an external force is applied to the button, the button moves in a direction closer to the detection device until the button is disengaged from the battery mounting cavity of the drone, at which point the button is in a second position, and the button contacts the detection device. The detection device then sends an electrical signal to a remote controller, causing the remote controller to control a robotic arm to remove the battery assembly from the battery mounting cavity of the drone.

[0007] In some embodiments, the button includes a latching portion, a pressing portion, and a contact element; the pressing portion is fixedly connected to the latching portion, and the button moves along the first direction by pressing the pressing portion; the latching portion is used to latch with the inner wall of the battery mounting cavity of the drone, and the contact element is disposed on the inner side of the pressing portion, and the contact element is used to contact the detection device.

[0008] In some embodiments, the reset member includes an elastic element that can extend or compress along the first direction. A first end of the elastic element is fixedly connected to the button, and a second end is fixedly connected to the base. When the button is engaged with the battery mounting cavity of the drone, the elastic element is in a compressed state.

[0009] In some embodiments, the reset member includes a first magnetic member and a second magnetic member that are magnetically repulsive and positioned opposite each other. The first magnetic member is fixedly connected to the side of the button near the base, and the second magnetic member is fixedly connected to the side of the base near the button.

[0010] In some embodiments, the base is provided with a limiting protrusion extending in a first direction, and the bottom of the button has a limiting groove that mates with the limiting protrusion.

[0011] In some embodiments, the detection device includes a circuit board and a detection switch, the detection switch being fixedly connected to the circuit board, the circuit board being fixedly connected to the inner side of the base, and the detection switch having detection contacts.

[0012] In some embodiments, the limiting device includes a pressure plate fixedly connected to the base; the snap-fit ​​portion of the button includes a vertical portion and a bent portion; when the button snaps into the battery mounting cavity of the drone, the vertical portion abuts against the pressure plate, so that the button abuts against the limiting device; when the button is released from the battery mounting cavity of the drone, the vertical portion separates from the pressure plate.

[0013] In some embodiments, the opening of the outer shell is provided with a first step structure, and the top edge of the base is provided with a second step structure. When the outer shell and the base are fixedly connected, the first step structure overlaps the second step structure.

[0014] An embodiment of the second aspect of this application provides a drone including the battery assembly described above.

[0015] In this embodiment, when it is necessary to remove the battery assembly from the drone's battery mounting cavity, simply press the button to move it along the first direction and disengage it from the drone's battery mounting cavity. When it is necessary to install the battery assembly into the drone's battery mounting cavity, press the button to insert the battery assembly into the cavity, and then release the button. The reset mechanism then engages the button with the cavity, thus installing the battery assembly. The operation is simple and the structure is straightforward. Furthermore, when the button disengages from the battery mounting cavity, a button contact detection device is activated. This device sends an electrical signal to a remote controller, which then controls a robotic arm to grasp the battery assembly, improving the intelligence of the battery assembly installation and removal process.

[0016] Of course, any product implementing this application does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0032] An embodiment of the first aspect of this application provides a battery assembly for use in a drone, such as... Figure 1 , Figure 2 and Figure 3As shown, the battery assembly includes: a battery 10 and a snap-fit ​​structure 20. The battery 10 is detachably connected to the battery mounting cavity of the drone via the snap-fit ​​structure 20. The battery 10 includes a housing 11 with an opening 110. The snap-fit ​​structure 20 includes a base 21, a button 22, a reset member 23, a limiting device 24, and a detection device 25. The base 21 is fixedly connected to the opening 110 of the housing 11. The detection device 25 and the limiting device 24 are respectively fixedly connected to the base 21. The button 22 is slidably connected to the base 21 along a first direction X. One end of the reset member 23 is connected to the base 21, and the other end is connected to the button 22. When an external force is applied to button 22, and the button 22 abuts against the limiting device 24 under the action of the reset member 23, button 22 is in the first position. Button 22 does not contact the detection device 25, so that the battery assembly is installed in the battery mounting cavity of the drone. When an external force is applied to button 22, button 22 moves in the direction close to the detection device 25 until button 22 is released from the battery mounting cavity of the drone. At this point, button 22 is in the second position, and button 22 contacts the detection device 25. The detection device 25 sends an electrical signal to the remote controller, so that the remote controller controls the robot to remove the battery assembly from the battery mounting cavity of the drone.

[0033] In this embodiment, the battery assembly is snapped into the battery mounting cavity of the drone via a snap-fit ​​structure 20. When the battery assembly needs to be removed from the drone's battery mounting cavity, simply press button 22 to move it along the first direction X. This releases button 22 from the inner wall 201 of the drone's battery mounting cavity until button 22 reaches the second position, where it contacts the detection device 25. The detection device 25 sends an electrical signal to the remote controller, causing the controller to control the robotic arm gripper to grasp the battery 10, thus improving the intelligence of the battery assembly loading and unloading process. When installing the battery in the drone's battery mounting cavity, press button 22 to retract it, preventing interference between button 22 and the inner wall 201 of the battery mounting cavity as the battery assembly is inserted. When the battery assembly is inserted to the point where button 22 and the drone's battery mounting cavity are engaged, release button 22. Under the action of reset member 23, button 22 moves along the first direction X, separating from the detection device 25. Button 22 then engages with the inner wall 201 of the drone's battery mounting cavity, thus enabling the battery assembly to be installed in the drone's mounting cavity. The operation is simple and the structure is straightforward.

[0034] It should be noted that during the installation of the battery assembly, when the robotic arm gripper releases button 22, causing button 22 to extend outward and disengage from the detection device 25 and engage with the battery mounting cavity of the drone, the detection device 25 can send a signal to the remote controller that the battery assembly is installed in place.

[0035] Specifically, such as Figure 4As shown, the inner wall 201 of the battery mounting cavity of the drone has a snap-fit ​​part 202. The snap-fit ​​part 202 can be a mating hole provided on the inner wall 201 corresponding to the battery mounting cavity, and at least a portion of the button 22 can extend into the mating hole.

[0036] Among them, such as Figure 1 As shown, the outer casing 11 of the battery 10 is provided with multiple heat dissipation holes 111 for dissipating heat from the battery cell 12 and improving the heat dissipation performance of the battery assembly.

[0037] In some embodiments of this application, such as Figure 2 and Figure 4 , Figure 5 As shown, button 22 includes a latching part 221, a pressing part 222, and a contact 223; the pressing part 222 is fixedly connected to the latching part 221, and the button 22 moves along the first direction X by pressing the pressing part 222; the latching part 221 is used to latch with the inner wall 201 of the battery mounting cavity of the UAV, and the contact 223 is located on the inner side of the pressing part 222 and is used to contact the detection device 25.

[0038] In this embodiment, the button 22 engages with the inner wall 201 of the battery mounting cavity of the drone via the snap-fit ​​part 221, the button 22 is pressed via the pressing part 222, and the button 22 contacts the detection device 25 via the contact part 223. The structure is simple, assembly is easy, and it better achieves miniaturization of the snap-fit ​​structure, improving space utilization. Furthermore, during the pressing of the pressing part 222, the button 22 can be disengaged from the battery mounting cavity in the drone, and the detection device 25 can be touched, making operation simple.

[0039] Specifically, such as Figure 2 As shown, the pressing part 222 of button 22 has a positioning hole 2221, through which the robotic arm gripper engages with the pressing part 222 of button 22. The base 21 also has a fork-like hole 217, through which the robotic arm gripper can grasp the battery assembly. In practical applications, the robotic arm gripper only needs to push the positioning hole 2221 along the first direction X to release the latching structure from the drone battery mounting cavity. The operation is simple and the process is straightforward, saving time in installing and removing the battery assembly. In practical applications, the distance between the contact 223 and the side of the pressing part closest to the contact 223 can be 5mm-8mm, allowing the battery assembly to be snapped in and detected within a 5mm-8mm space.

[0040] More specifically, such as Figure 1 , Figure 2 and Figure 4As shown, the battery 10 also includes a battery cell 12, which can be installed inside the housing 11 through the opening 110 of the housing 11. The battery cell 12 has a lead wire 121. The base 21 includes a bottom wall 214, a side wall 215, and a receiving groove 216. The side wall 215 is connected to the periphery of the bottom wall 214, so that the base 21 has a receiving space. The second connecting post 218 and the detection device 25 are located in the receiving space. The receiving groove 216 is provided on both sides of the bottom wall 214 along the first direction X. Correspondingly, there are also two buttons 22. The bottom wall 214 is provided with a battery cell support structure 2410, an indicator light mounting hole 2141, and a power button mounting hole 2142. The button 22 is located at the receiving groove 216. The side wall 215 corresponding to the receiving groove 216 is provided with a first through hole 2151. The contact 223 of the button 22 can pass through the first through hole 2151 and contact the detection switch 252 of the detection device 25.

[0041] Specifically, the number of detection switches 252 corresponds to the number of buttons 22. For example, when there are two buttons 22, there are also two detection switches 252.

[0042] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the reset member 23 includes an elastic member 231, which can extend or compress along the first direction X. The first end of the elastic member 231 is fixedly connected to the button 22, and the second end is fixedly connected to the base 21. When the button 22 is in the first position, that is, when the button 22 is engaged with the battery mounting cavity of the drone, the elastic member 231 is in a compressed state.

[0043] In this embodiment, when the button 22 is in the first position, the elastic member 231 is in a compressed state. The elastic force of the elastic member 231 can make the button 22 abut against the limiting device 24, so that the button 22 can be engaged with the battery mounting cavity in the drone.

[0044] Specifically, the elastic element 231 can be a spring or an elastic post. The elastic element 231 and the button 22 are connected by an interference fit.

[0045] In some embodiments of this application, the button 22 has a first guide post (not shown), the base 21 has a second guide post 213, the first end of the elastic member 231 is sleeved on the first guide post, and the second end is sleeved on the second guide post 213.

[0046] In this embodiment, the first guide post and the second guide post 213 can guide the compression process of the elastic member 231 along the first direction X, making the elastic member 231 more stable during the compression or release of pressure, thereby making the movement of the button 22 along the first direction X more stable.

[0047] More specifically, the first guide post is located on the side of the pressing part 222 of the button 22 near the base 21, and the second guide post 213 is located on the side wall 215 corresponding to the receiving groove 216.

[0048] In some embodiments of this application, the reset member 23 includes a first magnetic member (not shown) and a second magnetic member (not shown) that are magnetically repulsive and positioned opposite each other. The first magnetic member is fixedly connected to the side of the button 22 near the base 21, and the second magnetic member is fixedly connected to the side of the base 21 near the button 22.

[0049] In this embodiment, the first magnetic component and the second magnetic component are magnetically repulsive. When installing the battery assembly, pressing the pressing part 222 of the button 22 causes the button 22 to overcome the magnetic force between the first and second magnetic components, and the button 22 retracts. The battery assembly is then inserted into the battery mounting cavity of the drone. After aligning the snap-fit ​​part 221 of the button 22 with the snap-fit ​​mating part 202 of the battery mounting cavity of the drone, the button 22 is released. Under the action of the repulsive magnetic force, the button 22 moves in the first direction X in a direction away from the detection device 25. The snap-fit ​​part 221 extends into the snap-fit ​​mating part 202 of the inner wall 201 of the battery mounting cavity of the drone, thus completing the installation of the battery assembly.

[0050] In some embodiments of this application, such as Figure 2 and Figure 5 As shown, the base 21 is provided with a limiting protrusion 211 extending along the first direction X, and the bottom of the button 22 has a limiting groove 224 that cooperates with the limiting protrusion 211. The limiting protrusion 211 can slide along the limiting groove 224 to limit the button 22 from sliding on the base 21 along the first direction X.

[0051] In this embodiment, the limiting groove 224 of the button 22 cooperates with the limiting protrusion 211 on the base 21. The limiting protrusion 211 on the base 21 guides the movement of the button 22 along the first direction X, making the movement of the button 22 more stable.

[0052] In some embodiments of this application, such as Figure 1 , Figure 6 As shown, the detection device 25 includes a circuit board 251 and a detection switch 252. The detection switch 252 is fixedly connected to the circuit board 251, and the circuit board 251 is fixedly connected to the inner side of the base 21. The detection switch 252 has a detection contact 2521.

[0053] like Figure 2 , Figure 6 , Figure 7As shown, the outer casing 11 of the battery 10 is provided with a first connecting post 113, the first connecting post 113 is provided with a first connecting hole 1131, the base 21 is provided with a second connecting post 218, the second connecting post 218 is provided with a second connecting hole 2181, and the circuit board 251 is provided with a third connecting hole 2511.

[0054] Specifically, the detection switch 252 can be fixedly connected to the circuit board 251 by means of adhesive bonding, welding or threaded connection.

[0055] In some embodiments of this application, such as Figure 1 , Figure 4 , Figure 5 and Figure 8 As shown, the limiting device 24 includes a pressure plate 241, which is fixedly connected to the base 21; the snap-fit ​​portion 221 of the button 22 includes a vertical portion 2211 and a bent portion 2212. When the button 22 is in the first position, the vertical portion 2211 abuts against the side of the pressure plate 241 near the base 21, so that the button 22 abuts against the limiting device 24; when the button 22 is in the second position, that is, when the button 22 is released from the battery mounting cavity of the drone, the vertical portion 2211 separates from the side of the pressure plate 241 near the base 21.

[0056] Specifically, the limiting device 24 also includes a frame 242 disposed on the pressure plate 241. The pressure plate 241 and the frame 242 form a receiving hole 244. When the button 22 is in the first position, the bent part 2212 extends out of the receiving hole 244. When the button 22 is in the second position, at least a portion of the bent part 2212 enters the receiving hole 244. The receiving hole 244 can protect the button 22 in the second position.

[0057] More specifically, the pressure plate 241 is connected to the base 21 via the first connector 243, which can be a screw, and the pressure plate 241 is located above the receiving groove 216 of the base 21.

[0058] In some embodiments of this application, the outer shell 11 is provided with a first step structure 112 at the opening 110, and the bottom support 21 is provided with a second step structure 212 at the top edge. When the outer shell 11 and the bottom support 21 are fixedly connected, the first step structure 112 overlaps the second step structure 212.

[0059] An embodiment of the second aspect of this application provides a drone including the battery assembly described in the above embodiments.

[0060] In this embodiment, the battery assembly is snapped into the battery mounting cavity of the drone via a snap-fit ​​structure 20. When it is necessary to remove the battery assembly from the drone's battery mounting cavity, simply press button 22 to move it along the first direction X. This releases button 22 from the inner wall 201 of the drone's battery mounting cavity until button 22 reaches the second position, where it contacts the detection device 25. The detection device 25 sends an electrical signal to the remote controller, causing the controller to control the robotic arm gripper to grasp the battery 10. This improves the intelligence of the battery assembly loading and unloading process. When it is necessary to install the battery assembly into the drone's battery mounting cavity... When installing the battery in the battery mounting cavity, press button 22 to retract it, preventing interference between button 22 and the inner wall 201 of the battery mounting cavity as the battery assembly is inserted. When the battery assembly is inserted to the point where button 22 is engaged with the drone battery mounting cavity, release button 22. Under the action of reset member 23, button 22 moves along the first direction X, separating from detection device 25. Button 22 then engages with the inner wall 201 of the drone battery mounting cavity, thus enabling the battery assembly to be installed in the drone mounting cavity. The operation is simple, making the installation of the battery assembly in the drone easier.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application are included within the scope of protection of this application.
