DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-5 A carbon fiber drone shell that is easy to assemble comprises a shell 1 and a drone circuit board 3. A block 2 is bonded to the inner bottom wall of the shell 1. A first through hole 4 is provided on the upper surface of the shell 1. Two arc plates 5 are symmetrically slidably connected between the front surface of the inner wall and the rear surface of the inner wall of the first through hole 4. The lower surface of the arc plate 5 is in active contact with the upper surface of the block 2. A first connecting plate 6 and a second connecting plate 7 are bonded to the opposite sides of the two arc plates 5. The first connecting plate 6 is located above the second connecting plate 7. The front surface of the outer wall and the rear surface of the outer wall of the first connecting plate 6 are respectively in active contact with the front surface and the rear surface of the inner wall of the first through hole 4. Second through holes 8 are provided on both sides of the outer wall of the shell 1. A connecting rod 9 is bonded to the opposite side of the two arc plates 5. The outer wall of the connecting rod 9 is sleeved with a first spring 10. One end of the first spring 10 close to the arc plate 5 is bonded to the outer wall of the corresponding arc plate 5, and the end of the first spring 10 away from the arc plate 5 is bonded to the outer wall of the corresponding arc plate 5. Two first grooves 11 are symmetrically provided on the upper surface of the block 2 corresponding to the inner wall of the shell 1, the drone circuit board 3 is movably arranged on the upper surface of the block 2, and two first pins 12 are symmetrically provided on the bottom of the drone circuit board 3. A second groove 13 is provided on the inner bottom wall of the first groove 11, and a second spring 14 is bonded to the inner bottom wall of the second groove 13. A metal rod 15 is welded on the top of the second spring 14, and the top of the metal rod 15 contacts the bottom of the corresponding first pin 12. A third groove 16 is provided on the inner wall of the repelling side of the two first grooves 11, and two fourth grooves 17 are symmetrically provided on the lower surface of the block 2. The third groove 16 is connected to the corresponding fourth groove 17, and a second pin 18 is provided at the notch of the fourth groove 17. The bottom of the second pin 18 passes through the inner bottom wall of the shell 1, and the metal rod 15 and the corresponding second pin 18 are electrically connected by a wire 19 located in the third groove 16.

[0024] In the present invention, the diameter of the outer wall of the connecting rod 9 matches the inner diameter of the corresponding second through hole 8, and the connecting rod 9 and the corresponding second through hole 8 are located on the same horizontal line; the connecting rod 9 can be inserted into the interior of the second through hole 8, and the setting of the connecting rod 9 can guide the first spring 10, thereby preventing it from bending.

[0025] In the present invention, the upper surface of the first connecting plate 6 is provided with heat dissipation holes 20 which are arranged at equal intervals. By providing the heat dissipation holes 20 , the heat dissipation inside the housing 1 can be increased.

[0026] In the present invention, a dustproof net 21 is bonded to the inner wall of the heat dissipation through hole 20 ; the dustproof net 21 can prevent dust from entering the interior of the housing 1 through the heat dissipation through hole 20 .

[0027] In the present invention, the first connecting plate 6 and the corresponding second connecting plate 7 on the side away from the arc plate 5 both penetrate the inner wall of the shell 1 and are fixedly connected with the same handle 22; by providing the handle 22, not only can the pulling of the first connecting plate 6 and the second connecting plate 7 be made more convenient, but it can also serve as a limit for them.

[0028] In the present invention, a rubber pad 23 in close contact with the outer wall of the drone circuit board 3 is bonded to the side of the arc plate 5 away from the corresponding first connecting plate 6; by providing the rubber pad 23, the friction force on the surface of the arc plate 5 can be increased, so that its clamping of the drone circuit board 3 is more stable, and it can play a certain buffering role to prevent damage to the drone circuit board 3.

[0029] In the present invention, limiting grooves 24 are provided on both sides of the inner wall of the second groove 13 .

[0030] In the present invention, the inner side wall of the limiting groove 24 is slidably connected to the limiting block 25, and the side of the limiting block 25 away from the limiting groove 24 is welded to the outer side wall of the corresponding metal rod body 15; by setting the limiting groove 24 and the limiting block 25, the metal rod body 15 can be limited, thereby preventing it from moving out from the inside of the second groove 13.

[0031] Working principle: By pulling the handle 22, the corresponding first connecting plate 6 and the second connecting plate 7 are driven to move toward the outside of the shell 1. The two first connecting plates 6 and the two second connecting plates 7 pull the two corresponding arc plates 5 away from each other. The arc plate 5 will squeeze the corresponding first spring 10 to elastically deform, and drive the corresponding connecting rod 9 to be inserted into the second through hole 8. The connecting rod 9 can guide the first spring 10 to prevent it from bending. Then, the drone circuit board 3 is inserted into the shell 1, so that the first pin 12 is inserted into the first groove 11, and the pulling force on the handle 22 is relaxed. Then, the arc plate 5 will be elastically deformed by the first spring 10 and pushed back to its original position, thereby clamping the drone circuit board 3. When the first pin 12 is inserted into the first groove 11, the first pin 12 will push the metal rod body 15 to move toward the inside of the second groove 13 and squeeze the second spring 1 4 undergoes elastic deformation, thereby the metal rod body 15 is pushed back to its original position by the elastic deformation of the second spring 14, so that the metal rod body 15 is more closely contacted with the first pin 12, and then the first pin 12 is connected to the second pin 18 by the wire 19. When in use, the second pin 18 is welded to the circuit board. When the drone circuit board 3 is damaged, it is only necessary to pull the two handles 22 to make the two arc plates 5 move away again, release the clamping of the drone circuit board 3, and then remove the drone circuit board 3 from the inside of the shell 1, and then replace it. There is no need to repeatedly weld the circuit board, so that it is convenient to quickly disassemble and fix the drone circuit board 3 by clamping. The second spring 14 is compressed and tightened to improve the stability of the contact between the metal rod body 15 and the first pin 12. With the transfer method through the second pin 18, it is convenient for personnel to quickly disassemble and assemble the drone circuit board 3 in the future without repeated welding.

For ordinary technicians in this field, the specific meanings of the above terms in this utility can be understood according to specific circumstances.
