For another example shown in Fig. 3 and Figure 21, solar panels 80 are arranged on the mounting groove 37 of rake 35, and are electrically connected with circuit board 11, think that soft-package battery 71 charges, and ensure that board units continues normal work.Data-interface 15 is exposed by the socket 38 on back cover 30, for professional to board units upgrading or extraction data.

As shown in Fig. 3, Figure 22 and Figure 23, fore shell 20 comprises the caulking groove 22 suitable with panel 40, the display window 23 corresponding with display screen 60 position, the light hole 24 corresponding with light guide section 54 position of display/panel bracket 50, second hole clipping 25 corresponding with the second elastic clamping hook 32 and the resigning hole 26 corresponding with the 3rd elastic clamping hook 33; Fore shell 20 also comprises the first surface 27 relative with mainboard 10, the second surface 28 opposing with first surface 27, second surface 28 is positioned at the bottom land of caulking groove 22, panel 40 fits in bottom land, and the degree of depth of the thickness of panel 40 and caulking groove 22 is suitable, the edge of panel 40 and the either flush of caulking groove 22, in other embodiments, the edge of panel 40 also can a little less than the end face of caulking groove 22 or the end face a little more than caulking groove 22.

Display window 23, light hole 24, second hole clipping 25 and resigning hole 26 are through to second surface 28 by first surface 27, and preferably, display window 23 is connected with light hole 24, and display screen 60 is embedded in display window 23, and the light of pilot lamp 16 is appeared by light hole 24.The surface that panel 40 and second surface 28 are fitted is coated with light screening material, so that second surface 28, second hole clipping 25 and resigning hole 26 are blocked, panel 40 and display window 23, the region that light hole 24 is corresponding are transmission region, outwards show information for display screen 60 and pilot lamp 16.

As shown in Figure 23, Figure 24, the second hole clipping 25 compartment of terrain is distributed in the periphery of fore shell 20, and the medial surface of each the second hole clipping 25 is equipped with the chuck 251 matched with the second corresponding elastic clamping hook 32.Predetermined interval is formed between each chuck 251 and second surface 28, this interval is greater than the length of the dop of the second corresponding elastic clamping hook 32, when second elastic clamping hook 32 of order correspondence is sticked in this each chuck 251, the top of the second corresponding elastic clamping hook 32 is lower than second surface 28.In other embodiments, the interval formed between each chuck 251 with second surface 28 also can equal the length of the dop of the second corresponding elastic clamping hook 32, when second elastic clamping hook 32 of order correspondence is sticked in this each chuck 251, the top of the second corresponding elastic clamping hook 32 flushes with second surface 28.This snap fit can reduce the second elastic clamping hook 32 taking up room on board units thickness, allows board units can do thinner.

As shown in Figure 23, Figure 25, resigning hole 26 compartment of terrain is distributed in the periphery of fore shell 20, when the 3rd corresponding elastic clamping hook 33 is sticked on mainboard 10, the top of the 3rd corresponding elastic clamping hook 33 reaches in resigning hole 26, reduce the 3rd elastic clamping hook 33 taking up room on board units thickness, allow board units can do thinner.Panel 40 fits on second surface 28, and covers some second hole clippings 25 and resigning hole 26.In other embodiments, if dodge space enough, resigning hole 26 also can not exclusively run through, and is only by the blind hole of first surface 27 to second surface 28 direction indent.

As shown in Fig. 2, Figure 22 and Figure 23, in certain embodiments, plug-in card space is defined together with the first surface 27 of fore shell 20 by the back side 11b of circuit board 11, and insert port 21 is connected with plug-in card space.First surface 27 is provided with some abrasionproof bones 271, and abrasionproof bone 271 to be extended internally setting by insert port 21, and is positioned at first surface 27 region relative with plug-in card space.Abrasionproof bone 271 can prevent IC-card 90 from after repeatedly plugging, producing wearing and tearing on surface, also can reduce the resistance inserting plug-in card space simultaneously.

The first surface 27 of fore shell 20 be provided with on the position corresponding with dual-side 21c for IC-card 90 side holding by inserting plug-in card space clamping device 272, be used for limiting IC-card 90 and insert the guiding mechanism 273 of the direction of insertion in plug-in card space and be used for engaging the buckle 274 of IC-card 90.

Clamping device 272 comprises the elasticity engaging arm be arranged on the dual-side 21c of plug-in card space, and the end of elasticity engaging arm extend in plug-in card space.In other embodiments, also only elasticity engaging arm can be set on a side 21c, another side 21c be arranged the structures such as the position of bone to the common clamping position of IC-card 90.

Guiding mechanism 273 comprises the some guiding bones be disposed on respectively on two side 21c, and guiding bone is provided with guiding oblique angle near insert port 21 one end, to be imported in plug-in card space by IC-card 90.In other embodiments, also only guiding bone can be set on a side 21c, another side 21c arrange the structures such as the continuous position of bone to IC-card 90 guide and limit.

The engaging amount of buckle 274 is suitable with the thickness of IC-card 90, and after IC-card 90 is inserted into plug-in card space, the both sides of the edge of buckle 274 pairs of IC-cards 90 engage, and avoid IC-card 90 to rock in a thickness direction and cause card switch to disconnect.

As shown in Figure 26 and Figure 27, second and the 3rd in embodiment, also along the periphery in plug-in card space, the second card switch 17 can be set at the back side 11b of circuit board 11, the quantity of the second card switch 17 can be one or more, second card switch 17 can be arranged on the bottom 21d in plug-in card space, also can be arranged on the side 21c that plug-in card space two is relative, or be arranged on a side 21c in plug-in card space, or bottom 21d in plug-in card space and side 21c is arranged simultaneously.The triggering shell fragment of the second card switch 17 extend in plug-in card space, when IC-card 90 is inserted into plug-in card space, the edge of IC-card 90 offsets with triggering shell fragment and triggering shell fragment is out of shape, and allows the 3rd switch pin 132 of the second card switch 17, the 4th switch pin 133 connect.The thickness of the second card switch 17 is suitable with the thickness in plug-in card space, to make the second card switch 17 taking up room on board units thickness minimize, allows board units can do thinner.In other embodiments, the thickness in the thickness of the second card switch 17 also comparable plug-in card space is slightly large or slightly little.

Understandably, above-mentioned each technical characteristic can combination in any use and unrestricted.

The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
