[0021] 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 of the embodiments.

[0022] Reference Figure 1-6 A high-toughness and impact-resistant electronic circuit board includes a circuit board body 1, a functional component 6 is arranged on the upper part of the circuit board body 1, and buffer grooves 4 are opened on both sides, buffer pads 3 are arranged in the buffer grooves 4, and a toughening plate 5 is arranged at the bottom of the circuit board body 1, and a toughening strip 7 is embedded and installed on the toughening plate 5.

[0023] Furthermore, the circuit board body 1 is a rectangular parallelepiped, and a plurality of buffer grooves 4 are provided on both sides of its long sides. The strip-shaped notch design of the buffer groove 4 can cause the notch portion of the circuit board to deform to a certain extent when the circuit board is impacted, thereby absorbing and dispersing the impact force, reducing stress concentration, and improving the impact resistance of the circuit board.

[0024] The bottom of the circuit board body 1 is connected with a toughening plate 5 , which is provided with a plurality of notches, in which toughening strips 7 are embedded and fixedly connected, and the toughening strips 7 are arranged on the toughening plate 5 in a crisscross pattern.

[0025] Furthermore, a plurality of plug-in blocks 31 are provided at the bottom of the buffer pad 3, and the plug-in blocks 31 are limitedly clamped in the buffer groove 4, and the bottom of the plug-in blocks 31 is connected to the toughening strip 7, and is located on the outer side of the buffer pad 3 with rounded edges and embedded in the side of the circuit board body 1.

[0026] Furthermore, a protective frame 2 is connected around the outer side of the circuit board body 1, and a plurality of buffer blocks 8 are arranged inside the protective frame 2, and the buffer blocks 8 are in compression contact with the outer wall of the circuit board body 1. The buffer blocks 8 can effectively reduce the impact of external impact.

[0027] Furthermore, the protective frame 2 is slightly higher than the side edge of the circuit board body 1, and a connecting clamp 21 is provided at the bottom of the protective frame 2. The toughening strip 7 is clamped and connected in the connecting clamp 21, and the connecting clamp 21 is embedded in the groove opened at the bottom of the toughening plate 5.

[0028] In this embodiment, a toughening plate 5 is provided at the bottom of the circuit board body 1. The toughening plate 5 can effectively increase the overall toughness of the board body. At the same time, criss-cross toughening strips 7 are provided on the toughening plate 5 to further improve its bending resistance. At the same time, a protective frame 2 is connected to the toughening strips 7. The protective frame 2 is installed on the outer side of the circuit board body 1 to protect and buffer its edges to avoid damage to components on the board when the board is hit. At the same time, when the board is subjected to external impact force, the impact force is absorbed by the buffer pad 3, and the strip-shaped notch design of the buffer groove 4 can make the notch part of the circuit board undergo a certain deformation when it is impacted, thereby absorbing and dispersing the impact force, reducing stress concentration, and improving the impact resistance of the circuit board.

[0029] In the utility model, a toughening plate for increasing the overall toughness is provided at the bottom of the circuit board body 1, and criss-cross toughening strips 7 are provided on the toughening plate 5 to increase the overall toughness of the circuit board, relieve and reduce the bending of the board body, and the setting of the protective frame 2 and the buffer pad 3 can effectively relieve external impact force, improve impact resistance, and ensure the stable operation of the board.
