[0038] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0039] In one embodiment, Figure 1-Figure 5 As shown, a top frame connection module of a UAV truss includes a support base plate 1, a top end of the support base plate 1 is provided with a connection mechanism, and a plurality of support rods 4 are equidistantly provided on the outer side of the connection mechanism. The connection mechanism includes:

[0040] A positioning base plate 304 is fixedly connected to the top of the supporting base plate 1 by bolts, and a positioning top plate 302 is provided above the positioning base plate 304. The positioning top plate 302 and the positioning base plate 304 are respectively located above and below the plurality of support rods 4;

[0041] The connecting mechanism also includes:

[0042] The cam 304 is provided with a plurality of support blocks 305 which are equidistantly connected to the top of the positioning base plate 304. The top outer walls of the plurality of support blocks 305 are all in the shape of a square platform. The plurality of support blocks 305 are all inserted into the interior of the positioning top plate 302. The plurality of support blocks 305 are respectively located at one end of the plurality of support rods 4. The outer walls of the plurality of support blocks 305 are slidably sleeved with a positioning sleeve 301. The plurality of positioning sleeves 301 are in contact with the lower surface of the positioning top plate 302. The outer walls of the plurality of support blocks 305 are all sleeved with rubber rings 303. The rubber rings 303 are in contact with the inner wall of the positioning sleeve 301. The plurality of support rods 4 are respectively fixedly connected to the positioning sleeves 301 on the plurality of support blocks 305. The square platform-shaped outer wall allows the positioning top plate 302 to accurately sleeve the top outer wall of the support block 305. At the same time, the rubber ring 303 can effectively increase the friction between the positioning sleeve 301 and the support block 305.

[0043] The positioning bottom plate 304 is provided with a pushing mechanism for driving the positioning top plate 302 to rise and fall and rotate;

[0044] In this embodiment, the positioning top plate 302 can be pushed upward steadily by the pushing mechanism during use. At the same time, the positioning top plate 302 can be separated from the upper surface of the positioning sleeve 301 and the support block 305 by rising, thereby releasing the extrusion limit of the positioning sleeve 301.

[0045] At the same time, the pushing mechanism can rotate the positioning top plate 302 to displace the multiple support blocks 305, and then push the multiple support rods 4 in sequence to make the positioning sleeve 301 fit the outer wall of the support block 305. At this time, the rubber ring 303 can effectively increase the friction between the positioning sleeve 301 and the support block 305, so that the multiple support rods 4 can be easily installed.

[0046] When the positioning sleeves 301 at one end of the plurality of support rods 4 are all sleeved on the outer walls of the plurality of support blocks 305, the above operation is reversed, so that the positioning top plate 302 can be sleeved on the outer walls of the support blocks 305 and the upper surface of the positioning sleeve 301 can be squeezed, thereby achieving the purpose of convenient installation and fixation of the plurality of support rods 4, thereby further improving the efficiency of replacing the support rods 4;

[0047] In one embodiment, Figure 2-Figure 5 As shown, the push mechanism includes:

[0048] A telescopic assembly is provided on the top of the positioning base plate 304, and is used for the lifting and lowering displacement of the positioning top plate 302;

[0049] The telescopic components include:

[0050] A first fixing ring 203 is fixedly connected to the top of the positioning base plate 304. The first fixing ring 203 contacts the lower surface of the positioning top plate 302. A lifting ring 202 is slidably sleeved on the outer wall of the first fixing ring 203. The lifting ring 202 is fixedly connected to the positioning top plate 302 and contacts the upper surface of the positioning base plate 304.

[0051] The outer wall of the first fixed ring 203 is provided with a guide assembly, which is used to guide the movement of the lifting ring 202;

[0052] In one embodiment, Figure 3-Figure 5 As shown, the guide assembly includes:

[0053] A plurality of linear slide grooves 204 are circumferentially equidistantly provided on the outer wall of the first fixed ring 203. The first fixed ring 203 is provided with an arc guide groove 208 at the top of the plurality of linear slide grooves 204. The inner wall of the arc guide groove 208 is connected to the inner wall of the linear slide groove 204. The inner wall of the lifting ring 202 is circumferentially equidistantly fixed with a plurality of movable sliders 205. The plurality of movable sliders 205 are respectively located inside the plurality of linear slide grooves 204. The plurality of movable sliders 205 are slidably connected to the plurality of linear slide grooves 204. Through the mutual cooperation of the linear slide grooves 204, the movable sliders 205 and the arc guide grooves 208, the positioning top plate 302 can be rotated after being separated from the support block 305 during the rising process. The positioning top plate 302 can be dislocated with the plurality of support blocks 305 by rotating, so that the positioning sleeve 301 can slide up and down along the outer wall of the support block 305.

[0054] A limiting component is provided on the inner side of the first fixing ring 203, and the limiting component is used to limit the height of the positioning top plate 302;

[0055] In one embodiment, Figure 1-Figure 5 As shown, the limit assembly includes:

[0056] The connecting rotating rod 206 is located on the inner side of the first fixing ring 203, and extends to the outside of the top end of the positioning top plate 302. The connecting rotating rod 206 contacts the upper surface of the positioning bottom plate 304. The top end of the connecting rotating rod 206 is fixedly connected to the connecting rotating block 201, and the connecting rotating block 201 contacts the upper surface of the positioning top plate 302. The connecting rotating block 201 is used to limit and block the upper surface of the positioning top plate 302.

[0057] A connecting assembly is provided on the outer side of the connecting rod 206, and the connecting assembly is used to connect the lifting guide of the connecting rod 206;

[0058] In one embodiment, Figure 2-Figure 5 As shown, the connection components include:

[0059] A second fixing ring 207 is sleeved on the outer wall of the connecting rod 206. The second fixing ring 207 is fixedly connected to the positioning base plate 304. The second fixing ring 207 contacts the lower surface of the positioning top plate 302. The outer wall of the connecting rod 206 is provided with an external thread, and the inner wall of the second fixing ring 207 is provided with an internal thread that matches the outer wall thread of the connecting rod 206. The second fixing ring 207 is connected to the connecting rod 206 by a thread, so that the positioning top plate 302 can be squeezed and fixed.

[0060] A locking assembly is provided at the top of the positioning top plate 302, and the locking assembly is used to lock and limit the connection rotating block 201;

[0061] In one embodiment, Figure 1-Figure 5 As shown, the snap-fit assembly includes:

[0062] A rotating card plate 2010 is provided above the connecting rotating block 201. The rotating card plate 2010 extends through the interior of the connecting rotating block 201. The rotating card plate 2010 is slidably connected to the connecting rotating block 201. One end of the rotating card plate 2010 is rotatably connected to a fixed plate 2011 via a rotating shaft. The fixed plate 2011 is fixedly connected to the positioning top plate 302. The friction between the rotating card plate 2010 and the connecting rotating block 201 can prevent the connecting rotating block 201 from rotating during use.

[0063] An elastic component is provided on the outer side of the second fixing ring 207, and the elastic component is used to push the positioning top plate 302 upward;

[0064] In one embodiment, Figure 5 As shown, the elastic component is a spring 209 sleeved on the outer wall of the second fixing ring 207, one end of the spring 209 contacts the lower surface of the positioning top plate 302, and the other end of the spring 209 contacts the upper surface of the positioning bottom plate 304. The spring 209 can push the positioning top plate 302 to always contact the lower surface of the connecting rotating block 201, so that the positioning top plate 302 can rise synchronously with the connecting rotating block 201.

[0065] The above embodiment discloses a top frame connection module for a drone truss, wherein, when the present invention is in use, the rotating clamping plate 2010 is pulled about the rotating shaft as the axis to rotate to the end of the fixed plate 2011 away from the connecting rotating block 201, so that the rotating clamping plate 2010 and the connecting rotating block 201 are separated from each other, and the engagement limit of the connecting rotating block 201 is released. Then, the connecting rotating block 201 is rotated to drive the connecting rotating rod 206 to rotate. At this time, the connecting rotating rod 206 is threadedly connected to the second fixing ring 207, so that the connecting rotating rod 206 can be rotated and raised along the inner wall of the second fixing ring 207 by rotation, and the connecting rotating block 201 is simultaneously raised under the support of the connecting rotating rod 206.

[0066] During this process, the spring 209 can push the positioning top plate 302 to always contact the lower surface of the connecting rotating block 201 by rebounding, so that the positioning top plate 302 can rise synchronously with the connecting rotating block 201. At the same time, the positioning top plate 302 can separate from the upper surface of the positioning sleeve 301 and the supporting block 305 by rising, thereby releasing the extrusion limit of the positioning sleeve 301;

[0067] When the lifting block 205 is moved away from the inner wall of the linear slide 204 and contacts the inner wall of the arc guide groove 208, the lifting block 205 drives the lifting block 202 to rotate under the guidance of the inner wall of the arc guide groove 208. At the same time, the positioning top plate 302 rotates synchronously under the drive of the lifting ring 202, so that the positioning top plate 302 can be displaced with the multiple support blocks 305 by rotation. Then, the multiple support rods 4 are pushed in sequence to make the positioning sleeve 301 fit the outer wall of the support block 305. At this time, the friction between the positioning sleeve 301 and the support block 305 can be effectively increased by the rubber ring 303, thereby making it easy to install the multiple support rods 4.

[0068] When the positioning sleeves 301 at one end of multiple support rods 4 are all sleeved on the outer walls of multiple support blocks 305, the above operation is reversed at this time, so that the positioning top plate 302 can be sleeved on the outer wall of the support block 305 and the upper surface of the positioning sleeve 301 can be squeezed, so as to achieve the purpose of convenient installation and fixation of multiple support rods 4, thereby further improving the efficiency of replacing the support rods 4.

[0069] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
