Embodiment

Below in conjunction with accompanying drawing the utility model embodiment is further described; below just exemplary about the description of execution mode of the present utility model; be not in order to limit claimed theme of the present utility model; also there be the variation of more technology contents in the claim scope for the described embodiment of the utility model, all belong to the theme of the required protection of the utility model.

As accompanying drawing 1 to accompanying drawing 4, wherein, the 1st, pcb board, 2 is first pads, 3 is second pads, the 4th, screw, the 5th, lower house, the 6th, upper shell, the 7th, reference column, 8 is first hollow holes, 9 is second hollow holes, the 10th, and screwed hole, 11 is the 3rd hollow holes, the 12nd, circular hole, the 13rd, shock-damping structure.

To accompanying drawing 3, shock-damping structure 13 comprises pcb board 1, the first pad 2, the second pads 3, screw 4, the lower house 5 of controller, the upper shell 6 of controller as accompanying drawing 1; The reference column 7 of projection is arranged on the lower house 5, and reference column 7 is a cylinder, has on first pad 2 on first hollow hole, 8, the second pads 3 and has second hollow hole 9, and screwed hole 10 is arranged on the reference column 7, has on the pcb board 1 and the 3rd hollow hole 11, and circular hole 12 is arranged on the upper shell 6.

First pad 2, pcb board 1 and second pad 3, be enclosed within on the reference column 7 by the order that stacks under last, make reference column 7 pass first hollow hole 8, the 3rd hollow hole 11 and second hollow hole 9, thickness sum after this moment the stacking of first pad 2, second pad 3 and pcb board 1 is slightly larger than reference column 7, the first pads 2, pcb board 1 and second pad 3.The circular hole 12 of upper shell 6 is alignd with the screwed hole 10 of reference column 7, and upper shell 6 is pressed on second pad 3, press down back upper shell 6 contact reference columns 7 and press down reference column 7.Screw 4 is passed circular hole 12, screw in screw 4 in the screwed holes 10 then and screw, this moment, screw 4 pressed upper shell 6, thereby made upper shell 6 press second pad 2.First pad 2 was affixed on lower house 5, the first pads 2, pcb board 1, second pad 3 and was close to folded mutually from bottom to up this moment.
