Description

Technical Field

[0001] This application relates to the field of locking mechanism technology, and more particularly to a locking mechanism and a drone. Background Technology

[0002] A locking mechanism is a device used to securely connect two devices. For example, it can tightly lock a first device to a second device. Specifically, the locking mechanism can be integrated into the first or second device, or it can exist independently of the first and second devices.

[0003] In practical applications, such as the locking mechanism used in drones, the locking mechanism can be used to secure the connection between the drone's battery pack and the fuselage. This design facilitates quick disassembly and installation of the battery pack, enabling rapid battery replacement and effectively improving the drone's endurance.

[0004] In the process of developing this application, the applicant discovered that the locking mechanism in the prior art is assembled on the first device and locked to the lock groove of the second device by the latch. For example, in patent CN220293392 U, the flip cover is locked by the opening button. When unlocking, the opening button and the flip cover are unlocked by the linear movement of the opening button (which can be regarded as the latch) and the rotational movement of the flip cover (which can be regarded as the second device). This is not suitable for scenarios where the second device is not easy to rotate. Utility Model Content

[0042] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected to" another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," "inner," "outer," and similar expressions used in this specification are for illustrative purposes only.

[0043] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0044] For the reader's convenience in understanding this application, please refer to [link / reference needed]. Figure 1 and Figure 2 , Figure 1 and Figure 2 This is a schematic diagram showing the locking mechanism 100 provided in this application embodiment in both locked and unlocked states. Readers can... Figure 3 and Figure 4 First, roughly understand the status of the locking and unlocking mechanism 100 locking or unlocking the second device 300.

[0045] For the locking mechanism 100 provided in the embodiments of this application, please refer to Figure 5 The locking mechanism 100 includes a first locking member 10, a second locking member 20, a limiting member 30, an elastic member 40, a torsion spring 50, and a rotating shaft 60. The second locking member 20 is rotatably connected to an external first device 200 via the torsion spring 50 and the rotating shaft 60. The second locking member 20 is used to lock the external second device 300, thereby achieving locking between the external first device 200 and the second device 300. The limiting member 30 is connected to the second locking member 20 via the elastic member 40. The first locking member 10 can slide relative to the second locking member 20 along a first direction D1. The first locking member 10 and the second locking member 20 are locked together by the limiting member 30.

[0046] For the first locking element 10 mentioned above, please refer to Figure 6The first locking member 10 has a first locking groove 101 and a second locking groove 102 spaced apart along a first direction D1. Both the first locking groove 101 and the second locking groove 102 are used for the positioning member 30. A spacer portion 103 is provided between the first locking groove 101 and the second locking groove 102. The spacer portion 103 has a first inclined surface 1031 facing the first locking groove 101 and a second inclined surface 1032 facing the second locking groove 102. The first inclined surface 1031 and the second inclined surface 1032 are used to abut against the positioning member 30.

[0047] In addition, the first locking member 10 is also provided with a sliding part 104, which is used to slide relative to the second locking member 20 along the first direction D1, so as to realize the sliding of the first locking member 10 relative to the second locking member 20.

[0048] In addition, the first locking member 10 is provided with a stop portion 105, which is used to abut against the external first device 200 to restrict the movement of the second locking member 20.

[0049] Additionally, in some implementations of the embodiments of this application, please refer to... Figure 1 The first locking member 10 includes a first pushing part 106 and a second pushing part 107 disposed opposite to each other along the first direction D1. Both the first pushing part 106 and the second pushing part 107 are used to facilitate the user to push the first locking member 10 to slide relative to the second locking member 20.

[0050] It is understood that the sliding part 104 of the first locking member 10 can be connected to the first pushing part 106, or it can be connected to the second pushing part 107, or the sliding part 104 can be connected between the first pushing part 106 and the second pushing part 107. The sliding of the first locking member 10 relative to the second locking member 20 is achieved by pushing the first pushing part 106 or the second pushing part 107, specifically through the sliding part 104.

[0051] In this embodiment, the first direction D1 is not a single direction; rather, it encompasses two vector directions with opposite orientations, which together constitute the directional category represented by the first direction D1. The accompanying drawings provided in this application only exemplarily show one orientation of the first direction D1.

[0052] For the aforementioned limiting member 30 and elastic member 40, please refer to Figure 7 and combined Figure 8One end of the elastic member 40 is connected to the second locking member 20, and the other end of the elastic member 40 is connected to the limiting member 30, providing the limiting member 30 with elastic force in the direction of the first locking groove 101 or the second locking groove 102, ensuring that the limiting member 30 can be stably engaged in the first locking groove 101 or the second locking groove 102. Specifically, when the limiting member 30 is restricted to the second locking groove 102, by pushing the first pushing part 106, the first locking member 10 slides relative to the second locking member 20 in one of the directions of the first direction D1, and the elastic member 40 undergoes elastic deformation. Under the action of the pushing force of the first locking member 10 and the elastic deformation of the elastic member 40, the limiting member 30 can disengage from the second locking groove 102, bypass the gap 103 between the first locking groove 101 and the second locking groove 102, and then enter the first locking groove 101 and be restricted by the first locking groove 101; similarly, the limiting member 30 is restricted to the first locking groove 102. When the second pushing part 107 is pushed, the first locking member 10 slides relative to the second locking member 20 in one of the directions of the first direction D1. The elastic member 40 undergoes elastic deformation. Under the action of the pushing force of the first locking member 10 and the elastic deformation of the elastic member 40, the limiting member 30 can disengage from the first locking groove 101, bypass the gap 103 between the first locking groove 101 and the second locking groove 102, and then enter the second locking groove 102 and be limited by the second locking groove 102. In this way, the limiting member 30 can switch between the first locking groove 101 and the second locking groove 102.

[0053] In some embodiments, the elastic element 40 is a spring.

[0054] It is worth noting that, please refer to Figure 8 and combined Figure 7 When the limiting member 30 is located in the second locking groove 102, the stop portion 105 of the first locking member 10 abuts against the first device 200, and the movement of the first locking member 10 is restricted by the stop portion 105. The second locking member 20 is restricted to the first locking member 10 by the limiting member 30, and the movement of the second locking member 20 is also restricted. When the limiting member 30 is located in the first locking groove 101, the stop portion 105 of the first locking member 10 is not restricted by the first device 200, releasing the restriction on the first locking member 10 and the second locking member 20.

[0055] The implementation scheme in which the first locking member 10 abuts against the first device 200 to restrict the movement of the second locking member 20, and the implementation scheme in which the first locking member 10 releases its contact with the second locking member 20, will be described in detail in subsequent embodiments of the UAV.

[0056] It is worth noting that the way the first locking member 10 locks the second locking member 20 is not limited to the above-mentioned method of using the limiting member 30 and the elastic member 40. There may be other implementation schemes, such as the locking method of the locking member (equivalent to the first locking member 10 of this application) to the cover opening button (equivalent to the second locking member 20 of this application) in CN220293392 U.

[0057] For some implementations of this application, please refer to Figure 7 and combined Figure 6 The limiting member 30 has a third inclined surface 301 and a fourth inclined surface 302. When the limiting member 30 is located in the first locking groove 101, at least a portion of the third inclined surface 301 abuts against the first inclined surface 1031. When the limiting member 30 is located in the second locking groove 102, at least a portion of the fourth inclined surface 302 abuts against the second inclined surface 1032. By setting the first inclined surface 1031, the second inclined surface 1032, the third inclined surface 301, and the fourth inclined surface 302, the smoothness of the limiting member 30 switching between the first locking groove 101 and the second locking groove 102 is improved.

[0058] In some implementations of this application, the limiting member 30 includes a connecting part 31, a first limiting part 32, and a second limiting part 33. The connecting part 31 is connected to the other end of the elastic member 40, the first limiting part 32 is connected to the connecting part 31, and the first limiting part 32 is used to limit the first locking groove 101 or the second locking groove 102. The second limiting part 33 is connected to the connecting part 31 along the first direction D1, and the second limiting part 33 is used to abut against the second locking member 20, thereby improving the structural stability of the limiting member 30 as a whole connected to the second locking member 20 through the elastic member 40.

[0059] In some embodiments, there are two second limiting parts 33, which are connected to the connecting part 31 along the first direction D1, further improving the structural stability of the limiting member 30 as a whole connected to the second locking member 20 by the elastic member 40.

[0060] For clarity, the direction in which the first locking member 10 is stacked on the second locking member 20 is defined as the second direction D2, and the third direction D3 is defined, wherein the first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other. In some embodiments, there are two limiting members 30, which are spaced apart along the third direction D3. There are also two elastic members 40, one end of which is connected to the second locking member 20, and the other end of which is connected to the limiting member 30. The provision of two limiting members 30 improves the stability and reliability of the sliding of the first locking member 10 relative to the second locking member 20.

[0061] In addition, it is understandable that by setting the elastic element 40, the reliability of the limiting element 30 being restricted to the first locking groove 101 or the second locking groove 102 along the third direction D3 is improved, and the reliability of the first locking element 10 locking the second locking element 20 is improved.

[0062] It is understandable that when there are two limiting members 30, there are two first locking grooves 101, which are set along the third direction D3, and one first locking groove 101 is used to limit one limiting member 30; there are two second locking grooves 102, which are set along the third direction D3, and one second locking groove 102 is used to limit one limiting member 30.

[0063] For the second locking element 20, the rotating shaft 60, and the torsion spring 50 mentioned above, please refer to [link / reference]. Figure 9 The second locking member 20 is rotatably mounted to the external first device 200 via the rotating shaft 60. The spring body 51 of the torsion spring 50 is mounted on the rotating shaft 60, realizing the rotatable connection between the spring body 51 of the torsion spring 50 and the second locking member 20. The end 52 of the torsion spring 50 abuts against the second locking member 20, and the torsion arm 53 of the torsion spring 50 abuts against the first device 200.

[0064] In some implementations of this application, the second locking member 20 is provided with a sliding hole 201, and the sliding portion 104 of the first locking member 10 extends into the sliding hole 201. The sliding portion 104 is capable of sliding relative to the sliding hole 201 along a first direction D1. The sliding of the first locking member 10 relative to the second locking member 20 is achieved by the sliding of the sliding portion 104 of the first locking member 10 relative to the sliding hole 201 of the second locking member 20.

[0065] In some embodiments, there are two sliding holes 201, which are spaced apart along the first direction D1. There are also two sliding portions 104 of the first locking member 10, with one sliding portion 104 extending to one sliding hole 201, thereby improving the smoothness and reliability of the sliding of the first locking member 10 relative to the second locking member 20.

[0066] In some embodiments, the second locking member 20 has a stop portion 21, which limits the distance by which the first locking member 10 slides relative to the second locking member 20. For example, when the first locking member 10 is pushed to slide relative to the second locking member 20 along a first direction D1, the limiting member 30 switches from the second locking groove 102 to the first locking groove 101. The first locking member 10 is limited by the stop portion 21 of the second locking member 20, and the limiting member 30 cannot further disengage from the first locking groove 101 and move again.

[0067] In some implementations of this application, the stop portion 105 of the first locking member 10 may be restricted to the stop portion 21 of the second locking member 20.

[0068] For some embodiments of this application, please refer to Figure 7 The second locking member 20 is provided with an assembly groove 202 and an opening 2021 communicating with the assembly groove 202. One end of the elastic member 40 is connected to the groove wall of the assembly groove 202. At least a portion of the limiting member 30 (e.g., the connecting portion 31 of the limiting member 30, a portion of the first limiting portion 32 and the second limiting portion 33) is received in the assembly groove 202. One end of the limiting member 30 away from the elastic member 40 extends from the opening 2021 and is restricted to the first locking groove 101 or the second locking groove 102. Specifically, the first limiting portion 32 of the limiting member 30 extends from the opening 2021 and is restricted to the first locking groove 101 or the second locking groove 102.

[0069] In some embodiments of this application, the limiting member 30 abuts against the wall of the assembly groove 202 along the first direction D1. Specifically, the second limiting portion 33 of the limiting member 30 abuts against the wall of the assembly groove 202, improving the reliability of the limiting member 30 being connected to the second locking member 20 via the elastic member 40.

[0070] It is understandable that when there are two limiting members 30, there are also two assembly slots 202, and one limiting member 30 is connected to the wall of one assembly slot 202 through an elastic member 40.

[0071] In some embodiments, please refer to Figure 9 and combined Figure 5 The second locking member 20 has a mounting portion 22 for rotatably connecting with the first device 200. Specifically, a rotating shaft 60 passes through the mounting portion 22, and the second locking member 200 is rotatably connected to the first device 200 via the rotating shaft 60, thus enabling the second locking member 200 to be assembled onto the first device 200. The technical solution for assembling the second locking member 200 onto the first device 200 will be described in detail in subsequent embodiments of the UAV.

[0072] In some embodiments, please refer to Figure 8 and Figure 9 The second locking member 20 has a latching portion 23 for locking the second device 300. When the latching portion 23 is locked to the second device 300, and the mounting portion 22 rotates along the first rotation direction C1, the latching portion 23 disengages from the second device 300, thereby unlocking the latching portion 23 from the second device 300. When the mounting portion 22 rotates along the second rotation direction C2, which is opposite to the first rotation direction C1, the latching portion 23 can lock onto the second device 300. The locking and unlocking between the second locking member 20 and the second device 300 is achieved through the latching portion 23 of the second locking member 20; since the second locking member 20 is assembled to the first device 200, the locking and unlocking of the first device 200 and the second device 300 are achieved through the second locking member 20.

[0073] The locking method between the locking part 23 and the second device 300 will be described in detail in subsequent embodiments of the UAV.

[0074] Please also refer to Figures 7 to 9 Based on the foregoing description of locking and unlocking between the first locking member 10 and the second locking member 20, when the limiting member 30 is located in the second locking groove 102, the stop portion 105 of the first locking member 10 is used to abut against the first device 200, and the movement of the first locking member 10 is restricted by the stop portion 105. The second locking member 20 is restricted to the first locking member 10 by the limiting member 30, and the movement of the second locking member 20 is also restricted, that is, the second locking member 20 cannot rotate relative to the first device 200. When the limiting member 30 is located in the first locking groove 101, the stop portion 105 of the first locking member 10 is not restricted by the first device 200, releasing the restriction on the first locking member 10 and the second locking member 20. That is, the second locking member 20 can rotate relative to the first device 200, so that the second locking member 20 can rotate along the second rotation direction C2 and be locked to the second device 300 by the latch portion 23. The second locking member 20 can also rotate along the first rotation direction C1 and disengage from the second device 300 by the latch portion 23, thereby unlocking the second locking member 20 from the second device 300. After the latching part 23 is locked to the second device 300, the locking mechanism 100 achieves a first locking between the first device 200 and the second device 300. At this time, the first locking member 10 is pushed to switch the limiting member 30 from the first locking groove 101 to the second locking groove 102. The first locking member 10 (specifically, the stop part 105) abuts against the first device 200, and the movement of the first locking member 10 is restricted. The rotation of the second locking member 20, which is locked by the first locking member 10, is also restricted, thus achieving a double locking and improving the reliability of the locking mechanism 100 in locking the first device 200 and the second device 300.

[0075] It is worth noting that in some implementations of this application, the second locking member 20 locks the first device 200 and the second device 300 through the aforementioned latching part 23. The way in which the second locking member 20 locks the first device 200 and the second device 300 is not limited to the form of the latching part 23, but can also be in other ways, such as the way in which the cover opening button (which can be regarded as the second locking member 20 of this application) locks the flip cover (which can be regarded as the second device 300 of this application) in CN220293392 U.

[0076] In some embodiments, the latching portion 23 is provided with an inclined surface 231 so that the area of ​​the cross section of the latching portion 23 decreases along the second rotation direction C2, thereby facilitating the latching portion 23 to lock onto the second device 300 and facilitating the latching portion 23 to disengage from the second device 300.

[0077] The cross-section of the locking part 23 refers to the surface formed by transversely cutting the locking part 23 along the first direction D1 and the third direction D3.

[0078] In some embodiments, please refer to Figure 9 and Figure 10 The second locking member 20 is recessed in a direction opposite to the rotating shaft 60 (along the radial direction of the rotating shaft 60) to form a receiving groove 203, which is used to receive part of the spring body 51 of the torsion spring 50. The design of the receiving groove 203 can effectively reduce the friction and wear of the spring body 51 of the torsion spring 50 during operation. By receiving part of the spring body 51 of the torsion spring 50 in the receiving groove 203, the contact area between the spring body 51 and the surrounding parts is reduced, reducing the wear caused by friction, thereby extending the service life of the torsion spring 50.

[0079] In some embodiments, please refer to Figure 11 The second locking member 20 is provided with a mounting hole 204, and the end 52 of the torsion spring 50 passes through the mounting hole 204 and abuts against the second locking member 20. The mounting hole 204 improves the reliability of the end 52 of the torsion spring 50 being positioned on the second locking member 20.

[0080] In some embodiments, the second locking member 20 is provided with a receiving groove 205, and a mounting hole 204 is located at the bottom of the receiving groove 205. The end 52 of the torsion spring 50 passes through the mounting hole 204 and abuts against the bottom of the receiving groove 205. The receiving groove 205 provides a receiving space for the end 52 of the torsion spring 50, reducing the risk of wear on surrounding components by the end 52 of the torsion spring 50 when it rotates.

[0081] It is worth noting that in some embodiments, there are two ends 52 of the torsion spring 50, which are spaced apart. There are two receiving grooves 205, which are spaced apart along the third direction D3. There are two mounting holes 204, where the end 52 of one torsion spring 50 passes through a mounting hole 204 and abuts against the bottom of a receiving groove 205, thereby improving the stability and reliability of the torsion spring 50 assembled with the second locking member 20.

[0082] For some embodiments of this application, please refer to Figure 6 and Figure 7The locking mechanism 100 includes a first locking member 10, a second locking member 20, a limiting member 30, and an elastic member 40. The first locking member 10 is provided with a first locking groove 101 and a second locking groove 102 spaced apart along a first direction D1. One end of the elastic member 40 is connected to the second locking member 20, and the other end of the elastic member 40 is connected to the limiting member 30, which is used to limit the first locking groove 101 or the second locking groove 102. The first locking member 10 can be positioned relative to the second locking member 20 along... The first direction D1 slides to allow the limiting member 30 to switch between the first locking groove 101 and the second locking groove 102; the second locking member 20 is used to assemble with the first device 200 and lock the second device 300; when the limiting member 30 is located in the second locking groove 102, the first locking member 10 is used to abut against the first device 200 to restrict the movement of the second locking member 20; when the limiting member 30 is located in the first locking groove 101, the first locking member 10 releases the restriction on the movement of the second locking member 20. The locking mechanism 100 not only achieves a single locking of the first device 200 and the second device 300 through the second locking member 20, but also restricts and unlocks the movement of the second locking member 20 by the first locking member 10 through the limiting member 30 (specifically, when the limiting member 30 is located in the second locking groove 102, the first locking member 10 is used to abut against the first device 200 to restrict the movement of the second locking member 20; when the limiting member 30 is located in the first locking groove 101, the first locking member 10 partially disengages from the first device 200, thereby releasing the restriction of the first locking member 10 on the second locking member 20), achieving double locking, reducing the risk of locking mechanism 100 failure, and improving the reliability of locking mechanism 100 in locking the first device 200 and the second device 300.

[0083] For some embodiments of this application, please refer to Figure 8 and Figure 9The locking mechanism 100 includes a first locking member 10 and a second locking member 20; the first locking member 10 is movably connected to the second locking member 20, and the first locking member 10 is used to abut against the first device 200 to restrict the movement of the second locking member 20; the second locking member 20 has a mounting portion 22, which is used to be rotatably connected to the first device 200; the second locking member 20 has a latching portion 23, which can unlock from the second device 300 when the mounting portion 22 rotates along the first rotation direction C1, and can lock onto the second device 300 when the mounting portion 22 rotates along the second rotation direction C2 opposite to the first rotation direction C1. When the mounting part 22 rotates along the first rotation direction C1 using the locking mechanism 100, the locking part 23 also rotates along the first rotation direction C1, allowing the locking part 23 to disengage from the second device 300, thus unlocking the locking part 23 from the second device 300. In other words, unlocking the locking part 23 from the second device 300 can be achieved without rotating the second device 300. Similarly, when the mounting part 22 rotates along the second rotation direction C2, the locking part 23 can be restricted to the second device 300, thus locking the locking part 23 from the second device 300. In other words, locking the locking part 23 from the second device 300 can be achieved without rotating the second device 300.

[0084] In specific application scenarios, the first device 200 can be a battery pack 200a, and the second device 300 can be the shell 300a of a drone.

[0085] This application also provides an embodiment of a drone, such as... Figure 3 or Figure 4 As shown, the drone includes a battery pack 200a, a housing 300a, and a locking mechanism 100. The specific structure and function of the locking mechanism 100 can be found in the above embodiments and will not be repeated here. The second locking member 20 of the locking mechanism 100 is assembled to the battery pack 200a. The second locking member 20 is used to lock the second device 300, achieving the first locking described above. The first locking member 10 is used to abut against the battery pack 200a, restricting the movement of the second locking member 20, thus achieving the second locking described above.

[0086] In some embodiments, please refer to Figure 8 and Figure 9 The mounting portion 22 of the second locking member 20 is rotatably connected to the battery pack 200a. Specifically, the battery pack 200a is provided with a mounting groove 2001, the mounting portion 22 is received in the mounting groove 2001, and the mounting portion 22 is rotatably connected to the groove wall of the mounting groove 2001, so that the mounting portion 22 of the second locking member 20 can rotate relative to the battery pack 200a.

[0087] In some embodiments, the battery pack 200a is further provided with a stepped portion 2002 connected to the mounting groove 2001. The stepped portion 2002 is used to specifically abut against the stop portion 105 of the first locking member 10, thereby restricting the movement of the first locking member 10 and the second locking member 20.

[0088] In some embodiments, the latching portion 23 of the second locking member 20 is used to lock the second device 300. Specifically, the shell 300a of the drone is provided with a locking groove 3001. When the latching portion 23 rotates along the second rotation direction C2, the latching portion 23 is received in the locking groove 3001 to restrict the linear movement of the shell 300a and achieve locking of the shell 300a.

[0089] The working principle of the locking mechanism 100 in locking the battery pack 200a and the drone housing 300a is as follows: The battery pack 200a, equipped with the locking mechanism 100, moves towards the housing 300a. Pressing the locking mechanism 100 causes the mounting portion 22 of the second locking member 20 to rotate, and the entire locking mechanism 100 rotates along the second rotation direction C2 until the latch portion 23 of the second locking member 20 is restricted to the locking groove 3001 of the housing 300a, achieving a first-order lock. At this time, the first locking member 10 is pushed to slide along the first direction D1. The limiting member 30 switches from the first locking groove 101 to the second locking groove 102. The stop portion 105 of the first locking member 10 abuts against the step portion 2002 of the battery pack 200a. The step portion 2002 restricts the first locking member 10 and the second locking member 20. Even if the first locking member 10 and the second locking member 20 are pressed, the first locking member 10 and the second locking member 20 cannot rotate in the first rotation direction C1. The latch portion 23 of the second locking member 20 cannot disengage from the locking groove 3001 of the housing 300a, thus achieving double locking.

[0090] When unlocking is required, push the first locking member 10, and the limiting member 30 switches from the first locking groove 101 to the second locking groove 102. The stop part 105 of the first locking member 10 disengages from the step part 2002 of the battery pack 200a. Press the first locking member 10, and the mounting part 22 of the second locking member 20 rotates. The locking mechanism 100 rotates as a whole along the first rotation direction C1. The latch part 23 of the second locking member 20 disengages from the locking groove 3001 of the housing 300a, thereby unlocking the battery pack 200a and the housing 300a. At this time, the battery pack 200a can be separated from the housing 300a of the drone.
