Referring to fig. 1, fig. 1 is a schematic axial view of a model airplane according to an embodiment of the present invention, and a model airplane 10 provided by an embodiment of the present invention includes a bearing structure 100 and a fuselage 200. The bearing structure 100 is connected with the body 200 for maintaining the body 200 in a preset posture.

Referring to fig. 2 to 4, in one embodiment, the supporting structure 100 includes a fixing member 1100 and a supporting member 1200. The support member 1200 is provided with a connection assembly 1210. The connection assembly 1210 includes a first contact portion 1211 and a second contact portion 1212 connected to the first contact portion 1211. The fixing member 1100 is provided with a fitting body 1110. The mount 1100 is used to be coupled with the body 200. The attachment assembly 1210 has a first position and a second position relative to the mating body 1110. The mating body 1110 is used for pushing against the first contact portion 1211 and the second contact portion 1212 when the connecting assembly 1210 moves from the first position to the second position, so that the connecting assembly 1210 is switched from the original state to the yield state. The connection assembly 1210 in the second position can abut the mating body 1110 to maintain the support member 1200 and the fixture 1100 in a fixed relative position. The first contact portion 1211 and the second contact portion 1212 are spaced apart by a first distance in the original state, and the first contact portion 1211 and the second contact portion 1212 are spaced apart by a second distance in the yield state. Referring to fig. 3 and 4, the connecting element 1210 of fig. 3 is shown in a first position, and the connecting element 1210 of fig. 4 is shown in a second position. The first distance and the second distance both refer to the distance between the first contact portion 1211 and the second contact portion 1212 in the Y-axis direction, and the first distance is shown by the dashed line K in fig. 3. It should be understood that the second distance does not refer to a distance of a certain value, and the second distance is a concept relative to the first distance. In other words, in the process that the mating body 1110 pushes against the first contact portion 1211 and the second contact portion 1212, the distance between the first contact portion 1211 and the second contact portion 1212 changes, and any distance between the first contact portion 1211 and the second contact portion 1212 that is not equal to the first distance can be regarded as the second distance.

The supporting structure 100 includes a fixing member 1100 and a supporting member 1200, and when the supporting member 1200 moves from the first position to the second position, the engaging body 1110 can push against the first contact portion 1211 and the second contact portion 1212, so that the connecting member 1210 is switched from the original state to the yield state. That is, in the process of moving the supporting member 1200 from the first position to the second position, the engaging body 1110 pushes against the first contact portion 1211 and the second contact portion 1212, so that the distance between the first contact portion 1211 and the second contact portion 1212 is converted from the first distance to the second distance. And the connecting assembly 1210 in the second position can abut against the mating body 1110, so that the supporting member 1200 and the fixing member 1100 are relatively fixed. It will be appreciated that the connecting assembly 1210 in the yield state has a tendency to return to the original state. In this manner, the connection assembly 1210 in the second position can maintain abutment with the mating body 1110.

Also, since the connection member 1210 has a restoring force by being in its yield state, the restoring force that restores it to the original state is held in abutment with the fitting body 1110. The connecting member 1210 is separated from the mating body 1110 by an external force overcoming the restoring force, i.e., the connecting member 1210 is separated from the mating body 1110. Thus, the connection assembly 1210 is no longer relatively fixed with respect to the mating body 1110. That is, with this configuration, the connection assembly 1210 and the mating body 1110 can be easily separated from each other, and the detachable connection between the supporting member 1200 and the fixing member 1100 can be achieved.

Referring to fig. 2, it can be appreciated that the connection assembly 1210 can be switched between the original state and the yield state by bare hand. That is, the restoring force is overcome by bare hands to separate the connection assembly 1210 from the mating body 1110, thereby achieving the detachment between the support member 1200 and the fixing member 1100. Specifically, by moving the first contact portion 1212 and the second contact portion 1213 toward or away from each other by bare hands, the connection assembly 1210 can be separated from the fitting body 1110, thereby achieving detachment between the support member 1200 and the fixing member 1100.

In combination, the connecting assembly 1210 in the second position can abut against the mating body 1110 to keep the supporting member 1200 and the fixing member 1100 relatively fixed. That is, the support member 1200 and the fixing member 1100 can be maintained relatively fixed by moving the connection assembly 1210 from the first position to the second position. It is understood that the connection assembly 1210 can be moved from the first position to the second position by freehand actuation. That is, the supporting member 1200 can be installed on the fixing member 1100 by bare hands without using any auxiliary tool.

In the above embodiment, compared to the prior art in which the supporting member 1200 and the fixing member 1100 are detachably connected through a screw or other structures, the supporting member 1200 and the fixing member 1100 can be separated only by bare hands without using an auxiliary tool such as a screwdriver in the bearing structure 100 in this embodiment, so that the supporting member 1200 and the fixing member 1100 are more convenient to disassemble and assemble. Thus, the housing and carrying of the model airplane 10 can be facilitated.

In various embodiments, the original state and the yield state of the connection assembly 1210 are described. For convenience of description, the connecting member 1210 is taken as a metal material for illustration, and it is understood that the metal material has a certain rigidity, that is, the connecting member 1210 deforms at the limit of the deformation of the material and can restore to the original state by itself, that is, the connecting member 1210 in the yielding state has a restoring force to the original state as described in the embodiments. Of course, the connecting member 1210 may be made of other materials capable of elastic deformation, and the description thereof is omitted.

Referring to fig. 5, the mating body 1110 has a first slot 1111 and a second slot 1112. The first contact portion 1211 in the second position can abut against a groove wall of the first card slot 1111, so that the first contact portion 1211 and the groove wall of the first card slot 1111 are kept relatively fixed. The second contact portion 1212 in the second position can abut a slot wall of the second card slot 1112 to keep the second contact portion 1212 and the slot wall of the second card slot 1112 relatively fixed. In connection with the above-described embodiments, it will be appreciated that,

it will be appreciated that in the above embodiment, the connection assembly 1210 in the second position is in a yield state. As the connecting assembly 1210 in the yield state has a motion that self-returns to the original state or at least has a motion tendency to self-return to the original state. As such, based on the restoring force, the first contact portion 1211 can be snapped into the first card slot 1111, and the second contact portion 1212 can be snapped into the second card slot 1112. In this way, when the first contact portion 1211 and the second contact portion 1212 are not driven by external force, the first contact portion 1211 and the second contact portion 1212 can maintain the abutting relationship with the first card slot 1111 and the second card slot 1112.

In some embodiments, the connection assembly 1210 in the second position is in an original state. It should be noted that, in the present embodiment, during the process of moving the connecting assembly 1210 from the first position to the second position, the mating body 1110 still pushes the first contact portion 1211 and the second contact portion 1212, so that the connecting assembly 1210 is switched from the original state to the yield state. When the connecting element 1210 moves to the second position, the first contact 1211 and the second contact 1212 can be engaged into the first card slot 1111 and the second card slot 1112, respectively. Then the state of the connection assembly 1210 is dependent on the shortest distance between the first card slot 1111 and the second card slot 1112 at this time. That is, when the shortest distance between the first card slot 1111 and the second card slot 1112 is smaller than the first distance, the connection assembly 1210 in the second position is in the original state. It can be appreciated that the first contact 1211 and the second contact 1212 in the second position can abut a groove wall of the first card slot 1111 and a groove wall of the second card slot 1112, respectively. Therefore, the supporting member 1200 can still be fixed relative to the fixing member 1100.

That is, in the above embodiment, during the process of moving the connecting assembly 1210 from the first position to the second position, the mating body 1110 can push the first contact portion 1211 and the second contact portion 1212, so that the distance between the first contact portion 1211 and the second contact portion 1212 is changed from the first distance to the second distance. When the first contact portion 1211 and the second contact portion 1212 are respectively engaged with the first card slot 1111 and the second card slot 1112, the first contact portion 1211 and the second contact portion 1212 lose the pushing action of the mating body 1110. At this time, the distance between the first contact portion 1211 and the second contact portion 1212 can be restored from the second distance to the first distance or to approximately the first distance based on the restoring force. However, whether the distance between the first contact portion 1211 and the second contact portion 1212 can be restored to the first distance depends on the shortest distance between the first card slot 1111 and the second card slot 1112. If the shortest distance is equal to or less than the first distance, the distance between the first contact portion 1211 and the second contact portion 1212 can be restored to the first distance; otherwise, it is not.

Further, in the above embodiments, when the second distance is greater than the first distance, the connecting element 1210 can be disengaged from the first card slot 1111 and the second card slot 1112 by moving the first contact 1211 in the second position and the second contact 1212 in the second position away from each other. In this manner, the support member 1200 is removed from the fixing member 1100.

When the second distance is smaller than the first distance, the connecting assembly 1210 is disengaged from the first card slot 1111 and the second card slot 1112 by the first contact 1211 in the second position and the second contact 1212 in the second position. In this manner, the support member 1200 can be detached from the fixing member 1100 as well.

Referring to fig. 5 and 6, the matching body 1110 includes a body 1118, and a first inclined surface 1113 and a second inclined surface 1114 disposed on the body 1118. The first card slot 1111 and the second card slot 1112 are disposed on the body 1118. The first inclined surface 1113 is used for pushing the first contact portion 1211 when the connecting assembly 1210 moves from the first position to the second position. The second inclined surface 1114 is used for pushing the second contact portion 1212 when the connecting assembly 1210 moves from the first position to the second position. Thus, the connecting assembly 1210 can be switched from the original state to the yield state by the pushing action of the first inclined surface 1113 and the second inclined surface 1114. That is, the distance between the first contact portion 1211 and the second contact portion 1212 is switched from the first distance to the second distance by the pushing action of the first inclined surface 1113 and the second inclined surface 1114.

Referring to fig. 5, it is understood that in the above embodiment, the first inclined surface 1113 and the second inclined surface 1114 can be disposed on two opposite sides of the body 1118. The first slot 1111 and the second slot 1112 are also correspondingly disposed on two sides of the body 1118, which are respectively provided with a first inclined plane 1113 and a second inclined plane 1114. Referring to fig. 5, it can be understood that the first slot 1111 and the second slot 1112 are disposed at the same end of the body 1118 in the X-axis direction. Thus, when the connecting assembly 1210 slides from the first position to the second position along the first inclined plane 1113 and the second inclined plane 1114, the connecting assembly 1210 can slide to engage with the first slot 1111 and the second slot 1112.

Specifically, with continued reference to fig. 5 and 6, in one embodiment, the first inclined surface 1113 is connected to a groove wall of the first slot 1111; the second inclined surface 1114 is connected to a groove wall of the second slot 1112. In the direction from the first position to the second position, the distance between the first inclined surface 1113 and the second inclined surface 1114 is gradually increased, and the distance between the joint of the first inclined surface 1113 and the first card slot 1111 and the joint of the second inclined surface 1114 and the second card slot 1112 is greater than the vertical distance between the slot walls of the first card slot 1111 and the second card slot 1112. The direction pointing from the first position to the second position is referred to as the opposite direction of the X-axis in fig. 5. The distance between the junction of the first ramp 1113 and the first card slot 1111 and the junction of the second ramp 1114 and the second card slot 1112 is referred to as M in FIG. 5. The vertical distance refers to a distance between a groove wall of first card slot 1111 and a groove wall of second card slot 1112 in a Y-axis direction or a direction parallel to the Y-axis.

In the above embodiments, it is understood that the second distance is greater than the first distance. That is, when the connecting assembly 1210 moves from the first position to the second position, the first inclined surface 1113 can push the first contact portion 1211, and the second inclined surface 1114 can push the second contact portion 1212, so that the distance between the first contact portion 1211 and the second contact portion 1212 is increased to the second distance. Since the distance between the junction of the first inclined surface 1113 and the first card slot 1111 and the junction of the second inclined surface 1114 and the second card slot 1112 is greater than the vertical distance between the walls of the first card slot 1111 and the second card slot 1112, the first contact 1211 and the second contact 1212 can be automatically engaged with the first card slot 1111 and the second card slot 1112 based on the restoring force of the connecting assembly 1210. When the first contact portion 1211 and the second contact portion 1212 are driven without an external force, the first contact portion 1211 and the second contact portion 1212 can be held in contact with a groove wall of the first card slot 1111 and a groove wall of the second card slot 1112, respectively. When the supporting member 1200 needs to be detached from the fixing member 1100, the first contact portion 1211 and the second contact portion 1212 are driven to move away from each other, so that the first contact portion 1211 can be separated from the groove wall of the first card slot 1111, and the second contact portion 1212 can be separated from the groove wall of the second card slot 1112. Thereby completing the disassembly of the support 1200.

Referring to fig. 5 in combination with fig. 3 and 4, in an embodiment, the mating body 1110 further includes a first blocking portion 1115 and a second blocking portion 1116. The first blocking portion 1115 and the second blocking portion 1116 are both connected to the body 1118. A first space exists between the first stopper 1115 and the first slope 1113. The first contact portion 1211 is inserted into the space. There is a second spacing between the second stop 1116 and the second ramp 1114. The second contact portion 1212 is disposed through the second space. In connection with the above embodiments, it can be understood that the support member 1200 can be detached from the fixing member 1100 by moving the first contact portion 1211 and the second contact portion 1212 away from each other. Moreover, since the first blocking portion 1115 and the first inclined surface 1113 respectively form two opposite side walls of the first interval, the first contact 1211 and the second contact 1212 can be prevented from being separated from each other by the first blocking portion 1115 under the condition of gravity or misoperation of the main body 200, and therefore, the first contact 1211 and the second contact 1212 are prevented from being separated from the groove walls of the first card slot 1111 and the second card slot 1112 respectively. In other words, the first stopper 1115 and the second stopper 1116 can restrict the first contact 1211 and the second contact 1212 from moving in a direction away from each other.

In one embodiment, the body 1118 is formed with a slot (not shown, the same applies below). The first inclined surface 1113 and the second inclined surface 1114 are two groove walls of the sliding groove. The first inclined plane 1113 is connected with the groove wall of the first clamping groove 1111; the second inclined surface 1114 is connected to a groove wall of the second slot 1112. The distance between the first inclined surface 1113 and the second inclined surface 1114 gradually decreases in a direction in which the first position points to the second position. The distance between the junction of the first bevel 1113 and the first slot 1111 and the junction of the second bevel 1114 and the second slot 1112 is less than the vertical distance between the walls of the first slot 1111 and the second slot 1112.

In the above embodiments, it is understood that the second distance is smaller than the first distance. That is, when the connecting assembly 1210 moves from the first position to the second position, the first inclined surface 1113 can push the first contact portion 1211, and the second inclined surface 1114 can push the second contact portion 1212, so that the distance between the first contact portion 1211 and the second contact portion 1212 decreases to the second distance.
