Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-2, the present utility model provides the following technical solutions: the utility model provides a piezo-resistor heat radiation structure, including piezo-resistor main part 1, set up the terminal 2 at piezo-resistor main part 1 both ends, the below of terminal 2 is provided with first support frame 3, and the outside of first support frame 3 is provided with second support frame 4.
The first support frame 3 and the terminal 2 are integrated into one piece structure, and the first support frame 3 is the component that the structure of falling "T" style of calligraphy was made for the first support frame 3 has the perpendicular power of supporting to the terminal 2, the second support frame 4 and the first support frame 3 are integrated into one piece structure, and the central axis of second support frame 4 slope in the central axis of first support frame 3, make the second support frame 4 have the holding power of slope to the first support frame 3, second support frame 4 is provided with two with the central axis symmetry of first support frame 3, and the upper end and the terminal 2 of second support frame 4 are connected, make the second support frame 4 all have holding power to the both sides of first support frame 3.
Through set up first support frame 3 and install second support frame 4 in the both sides of first support frame 3 in the below of terminal 2, because of the component that first support frame 3 was made for "T" style of calligraphy structure down, make piezoresistor main part 1 when being pushed down perpendicularly ascending holding power, prevent that first support frame 3 from taking place to crooked, because of the central axis slope of second support frame 4 is in the central axis of first support frame 3, when making piezoresistor main part 1 by controlling the promotion, there is the holding power of slope, prevent that first support frame 3 from taking place to crooked, first support frame 3 and second support frame 4 support this piezoresistor main part 1 and terminal 2, support through piezoresistor main part 1 and terminal 2, the below of piezoresistor main part 1 and terminal 2 can contact and first support frame 3 and second support frame 4 have also increased the radiating area, make the radiating effect become high, thereby the purpose of improving the radiating effect has been reached.
