Detailed Description

The utility model will now be described in detail with reference to specific embodiments, it being emphasized that the following description is merely exemplary in nature and is in no way intended to limit the scope of the utility model or its applications.

It is noted that unless explicitly specified and limited otherwise, the terms "center", "longitudinal", "transverse", "upper", "lower", "vertical", "horizontal", "inner", "outer", etc., used in this specification are directional or positional relationships indicated based on the drawings, and are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model. The terms "mounted," "connected," "secured," and the like are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated; thus, a feature defining "a first", "a second" may include one or more such features, either explicitly or implicitly; the meaning of "plurality" is two or more; "and/or" includes any and all combinations of one or more of the associated listed items. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

By "locking mechanism" is meant a component provided on a drone or other suitable type of mobile vehicle for helping to lock a stationary battery or similar functional module. A typical locking mechanism is generally capable of switching between "locked" and "unlocked" states. Wherein in the locked state the battery can be fixed in the target position and in the unlocked state the battery will not be hindered or allowed to leave from the target position. Thereby, replacement of the battery or the like functional module is achieved.

Fig. 1 is a schematic diagram of a locking mechanism according to an embodiment of the present utility model. Fig. 2 is a schematic view of the locking mechanism of fig. 1 with portions of the mechanism housing removed. As shown in fig. 1 and 2, the locking mechanism may include: mechanism housing 100, sliding member 200, and locking member 300.

The mechanism housing 100 is an outer housing of the whole locking mechanism, and is used for providing a containing space and a corresponding installation and fixing position. It may have any suitable shape or size according to the actual situation, and is not particularly limited herein. For example, as shown in fig. 1, it may be a substantially rectangular parallelepiped in shape, or as shown in fig. 4, the mechanism case 100 may be composed of two separate parts, a bottom case 102 and a cover plate 101 provided on the bottom case 102, for ease of assembly.

The slide member 200 is movably mounted to the mechanism case 100, and is movable as a movable member to reciprocate between a first position A1 and a second position A2 in the first direction X1. Any suitable type of connection structure can be specifically selected and used between the sliding member 200 and the mechanism housing 100 according to the actual situation, and only the sliding member 200 needs to be guided to move along a set track.

For example, as shown in fig. 4, the mechanism housing 100 may be provided with a through groove 110 extending in the first direction. The sliding member 200 is correspondingly provided with a slider or other similar member adapted to the through slot 110. Thereby, the sliding member 200 is guided to move in the first direction by the guiding action of the through groove 110. Alternatively, guide grooves or other similar components may be used instead of the through grooves 110.

In the present embodiment, terms such as "first position" and "second position" are used to indicate two extreme positions of the movement locus of the slide member 200, respectively. Which may be specifically set or determined according to the needs of the actual situation, and is not limited herein.

The locking member 300 is a structural member for fixing a battery or the like functional module. It is also a movable part, by which the switching of the locking mechanism between the unlocked and the locked state can be achieved by a change in its relative position.

In the present embodiment, there is a linkage relationship between the lock member 300 and the slide member 200. This is achieved by providing the locking member 300 with a guide rail 310 extending in the second direction X2 and restricting at least a portion of the sliding member 200 to move within the guide rail. The term "linkage" as used above describes the situation where there is a correlation in movement between two components. I.e. the movement of the sliding member may bring about the movement of the locking member and vice versa.

In addition, as shown in fig. 2, the first direction X1 and the second direction X2 may have a predetermined angle therebetween, so that the sliding member and the locking member move in different directions. The included angle may be specifically set by the skilled person according to the actual situation (e.g. specific dimensions of the components), and is not limited herein. For example, the first direction X1 is a direction substantially parallel to the longitudinal direction of the mechanism case, and the second direction X2 is a direction inclined with respect to the first direction X2.

In actual use, as shown in fig. 1, when the sliding member 200 moves to the first position A1, the locking member 300 correspondingly moves to a position (e.g., the cover plate 102) close to the mechanism housing under the guiding action of the inclined guiding rail 310, so that at least a portion of the locking member protrudes from the mechanism housing 100. The portion of the locking member 300 protruding from the mechanism housing 100 can abut against or block the movement of the battery or the like, thereby causing the battery or the like to be locked.

As shown in fig. 3, when the sliding member 200 moves to the second position A2 in the opposite direction, the locking member 300 moves to a position away from the mechanism housing by the guiding action of the inclined guiding rail 310, and thus, the portion of the locking member 300 protruding from the mechanism housing is recovered into the mechanism housing 100 (i.e., the locking member 300 is entirely accommodated in the mechanism housing). At this time, the battery is no longer blocked and can be smoothly taken out from the battery compartment or the like.

The locking mechanism provided by the embodiment of the utility model can conveniently realize the switching between the locking state and the unlocking state by shifting the sliding part between the first position and the second position. The whole unlocking/locking operation process is simple and convenient, and the use experience of a user is improved. Moreover, the locking part locks the battery in a mode of protruding out of the mechanism shell, and compared with a mode of relying on elastic deformation such as a buckle, the battery locking device can provide better stability and reliability and ensure that the battery is reliably locked at a proper position of the unmanned aerial vehicle.

Fig. 4 is an exploded view of a locking mechanism according to an embodiment of the present utility model. As shown in fig. 4, the sliding member 200 may include: the sliding portion 210 and the guide shaft core 220.

Wherein the sliding portion 210 is a component located outside the mechanism housing. Which can be contacted by a user to reciprocate between a first position and a second position under the influence of an external force. In the present embodiment, for ease of description, a side of the sliding portion 210 close to the mechanism housing is referred to as a first surface, and the other side away from the mechanism housing is referred to as a second surface, which is away from the first surface.

In some embodiments, a push button 230 may be further provided on the second surface of the sliding portion 210 for the convenience of the user. As shown in fig. 4, at least a part of the surface of the push button 230 is provided as a wavy friction surface. The friction surface body may be formed with a continuous plurality of grooves to form an uneven surface to help the user push the sliding portion more easily. Of course, it is also possible to use a surface in which projections are arranged at a specific density to form particles, or other surfaces having a higher friction coefficient instead.

The guide shaft core 220 extends outward from the first surface of the sliding portion by a predetermined length. The specific length value can be set according to the actual situation, and only needs to pass through the mechanism shell and reach the guide rail 310. For example, a value close to the width of the rectangular parallelepiped mechanism case is set.

In some embodiments, the through slot 110 extending in the first direction may have a width that is adapted to the guide shaft 220, as is adapted to the guide shaft 220. Thus, the guide shaft 220 passing through the through-groove 110 can reciprocate the sliding portion only in the extending direction (i.e., the first direction) of the through-groove under the restriction of the through-groove.

In some embodiments, referring to fig. 4, the guide shaft 220 may be more than two. Two or more guide shafts are provided on a first surface of the sliding portion in a first direction (2 are exemplified in the drawings of the present specification).

By providing two or more guide shafts 220 arranged in the first direction, a linking effect between the slide member and the locking member can be ensured, so that the locking member can smoothly move along a predetermined movement locus without unnecessary displacement.

In other embodiments, the portion of the sliding member 200 that is constrained to move within the guide track 310 may be the guide core 220 as described above. With continued reference to fig. 4, the guide track 310 may include: a rail body 311, a first receiving end 312 and a second receiving end 313.

The rail main body 311 extends in the second direction, has a width adapted to the guide shaft 220, and is a main body portion of the entire guide rail. The first receiving end 312 and the second receiving end 313 are located at both ends of the rail body, respectively.

The two receiving ends are two limit positions to which the guide shaft 220 can move, and correspond to the first position and the second position, respectively. Specifically, when the slide member 200 moves to the first position, the guide shaft 220 moves to the first receiving end 312. And when the slide member 200 is moved to the second position, the guide shaft core is moved to the second receiving end 313.

Specifically, the guide rails 310 may have the same number as the guide cores 220, for example, two as shown in fig. 4, to implement the pairing process with the guide cores 220.

In other embodiments, with continued reference to fig. 4, the locking mechanism may further include: microswitch 400 and pressure plate 500.

The micro switch 400 is a device capable of forming different electrical signals (e.g., high level/low level) according to the mechanical force applied thereto. The micro switch of a proper type can be selected according to the actual situation, and the micro switch is not particularly limited.

The pressing plate 500 is fixedly connected with the sliding member 200. Which can move with the sliding member 200 to contact or disengage the micro switch 400. Specifically, the pressing plate 500 may be fixedly connected to the sliding member 200 in any suitable manner according to the actual situation. For example, the pressure plate 500 may be fixedly coupled to the end of the guide shaft 220 passing through the mechanism housing, thereby achieving a fixed connection with the sliding member 200.

In this embodiment, the micro switch 400 may be disposed at one side of the inside of the mechanism housing. When the slide member 200 moves to the first position, the pressing plate 500 that follows the movement of the slide member 200 can be brought into contact with the micro switch 400, thereby applying a mechanical force to the micro switch 400. Accordingly, the micro switch 400 may form the first signal. When the sliding member 200 moves from the first position to the second position, the pressing plate 500 moving along with the sliding member 200 is separated from (i.e. no longer in contact with) the micro switch 400, and at this time, the micro switch is no longer mechanically acted on, so as to form a second signal accordingly.

Through the above-mentioned micro-gap switch and the clamp plate that additionally set up, can realize that the battery is installed and is put in place automated inspection's function to effectually promoted user's use experience, ensured unmanned aerial vehicle flight's safety.

Specifically, when the battery is not in place or the locking mechanism is not switched to the locked state, no mechanical force is applied thereto since the pressing plate 500 is disengaged from the micro switch 400. Thus, the second signal is continuously provided. The flight control or other similar processor of the unmanned aerial vehicle can determine that the battery is in an unreliable locked state at the moment according to the second signal, and inhibit the normal operation of the unmanned aerial vehicle or send a corresponding prompt signal to a user. And when the battery is mounted in place and the locking mechanism is switched to the locked state, a mechanical force is applied to the micro switch 400 due to the pressing plate 500. Thus, the first signal is continuously provided. The flight control or other similar processor of the drone can determine from the presence of the first signal that the battery has been reliably locked at this time, either to allow the drone to operate normally or to send a corresponding acknowledgement signal to the user.

In some embodiments, with continued reference to fig. 4, the locking member may include: a component base 320, a tongue 330, and an elastic component 340.

The component base 320 is housed in the mechanism case 100 and is movable in the height direction of the mechanism case 100 having a rectangular parallelepiped shape. The specific shape and size of the component base 320 may be set according to the actual situation, and only need to be accommodated therein. For example, is sized to approximate the mechanism housing 100. Specifically, the guide rail 310 may be provided on the component base 320. The reciprocation of the slide member in the first direction may correspondingly move the member base 320 away from or toward the mechanism housing surface.

The latch 330 is fixed to the component base 320 to protrude from the surface of the component base 320. The latch 330 is a portion that can protrude or be retracted into the mechanism case 100 to block or abut against the battery. Specifically, as shown in fig. 4, the locking bolt 330 may have a wedge-like structure, and two bolts are provided.

In some embodiments, as shown in fig. 4, the cover plate 102 of the mechanism housing may further be provided with a through hole 120 adapted to the latch, so that the latch 330 may protrude from the mechanism housing through the through hole, thereby implementing locking of the battery or similar functional module.

The elastic member 340 is a member having elastic deformability. Which is capable of storing elastic potential energy and applying elastic force outwards. In this embodiment, the elastic member 340 may be a compression spring. The two ends of the elastic member are respectively abutted against the mechanism housing and the member base, and the elastic force can be applied to the member base 320.

Specifically, the elastic force is a force for driving the component base to move in the direction X3 approaching the through hole. In other words, the component base 320 has a tendency to automatically return to close to the cover plate 102 under the action of the elastic component 340.

In the actual use process, when the sliding component 200 moves to the first position, the component base will move upwards to a position close to the through hole 120 under the action of the elastic component 340, and the locking tongue 330 protruding from the component base will protrude from the mechanism housing through the through hole 120, so as to lock the battery. When the sliding member 200 moves to the second position in the opposite direction, the member base 320 moves downward to a position away from the through hole 120, and the latch 330 is also retracted into the mechanism housing and does not protrude from the mechanism housing, thereby releasing the battery lock.

In some embodiments, as shown in fig. 5, the guide rail 310 may further include a movement blocking portion 314. The movement blocking portion 314 is a member provided in the guide rail for applying resistance against movement of the guide shaft 220.

It may be disposed at an interface between the rail body and the first receiving end and/or the second receiving end, so that the sliding member 200 may be pushed by a relatively large external force to move into position when moving to the first position and/or the second position. In the present embodiment, the movement blocking portion 314 is provided at the boundary position between the two housing ends, for example. Of course, it is also possible to provide only the boundary position of one of the accommodation ends.

With the additionally provided movement inhibitor 314, the user will have a phase of applying additional force just before pushing the slide member to the first and second positions. Such a design can provide a good position indication to effectively assist the user in determining whether the sliding member has been pushed into place.

Specifically, with continued reference to fig. 5, the movement inhibitor 314 may be implemented by a set of protrusions 314a and recesses 314 b.

Wherein the protrusion 314a protrudes from the surface of the rail body 311 and occupies at least a portion of the space of the guide rail. The recess 314b is located opposite to the protrusion 314a, is recessed inward from the surface of the rail body 311, and constitutes a large space so that the guide shaft core can pass over the protrusion.

In actual use, as shown in fig. 6, the guide shaft 220 is blocked by the protrusion 314a when moving to the boundary position of the first end. At this time, the user needs to apply a larger force to the sliding member 200 to pass the guide shaft core 220 over the protrusion 314a. After passing over the projection 314a, the guide shaft 220 is accommodated in the first accommodation end 312 (at this time, the sliding member is also moved to the first position accordingly).

As shown in fig. 7, the guide shaft 220 is also blocked by the protrusion 314a when it moves to the boundary position of the second end. At this time, the user needs to apply a larger force to the sliding member 200 to pass the guide shaft core 220 over the protrusion 314a. After passing over the projection 314a, the guide shaft 220 is accommodated in the second accommodation end 313 (at this time, the sliding member is also moved to the first position accordingly).

It should be noted that, based on the movement blocking portion principle shown in fig. 6 and 7, a person skilled in the art may also adjust, deform or replace the specific structure thereof, and only need to form a discontinuous bending structure at the interface between the rail main body and the receiving end, which is not limited to the specific structure shown in fig. 6 and 7.

Based on the locking mechanism provided by the embodiment of the utility model, the utility model further provides the unmanned aerial vehicle. The unmanned aerial vehicle may include: fuselage, battery and locking mechanism as described above.

Wherein, be provided with the battery compartment that is used for acceping the battery in the fuselage, locking mechanism is set up in the battery compartment. The battery is designed in a detachable and replaceable structure. When unmanned aerial vehicle normal use, the battery passes through locking mechanism locking and fixes in the battery compartment. When the battery needs to be replaced, the battery is taken out from the battery bin and replaced after the locking mechanism is unlocked to the battery.

In actual use, the locking mechanism is in a locked state when at least a portion of the locking member of the locking mechanism protrudes from the mechanism housing of the locking mechanism, as shown in fig. 1. The protruding locking member abuts the battery, locking the battery in the battery compartment. As shown in fig. 3, the lock mechanism is in the unlocked state when the lock members of the lock mechanism are all accommodated within the mechanism housing of the lock mechanism. The locking of the battery is released, so that the battery can be taken out from the battery compartment.

It should be noted that, in the embodiments of the present utility model, a unmanned aerial vehicle is described as an example. However, those skilled in the art may apply the locking mechanism to various other types of mobile carriers as needed in the actual situation, and is not specifically limited herein.

The foregoing is a further detailed description of the utility model in connection with specific/preferred embodiments, and it is not intended that the utility model be limited to such description. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model, and these are all within the scope of the utility model.
