Embodiment

Below will disclose a plurality of execution mode of the present invention with accompanying drawing, as clearly stated, the details on many practices will be explained in the following description.Yet those of ordinary skill in the art should recognize, in part execution mode of the present invention, the details on these practices is also non-essential, does not therefore use to limit the present invention.In addition, for the purpose of simplifying accompanying drawing, some known habitual structures and assembly will illustrate in the mode of simple signal in the accompanying drawings.

Fig. 1 illustrates the constitutional diagram according to the portable electric system of an embodiment of the present invention.Fig. 2 illustrates the explosive view of the execution mode of Fig. 1.As shown in Figure 1 and Figure 2, this portable electric system comprises a underframe 100, a bracing frame 400, one first support 200, the-second support 300, an electric equipment 700 and solar panels 600.Bracing frame 400 comprises one first support column 410 and one second support column 420 at least.The first support 200 and the second support 300 are to be set up in underframe 100.Electric equipment 700 is to be arranged on underframe 100.Solar panels 600 are to be set up on bracing frame 400, so as to producing electric power and providing to electric equipment 700.As shown in Figure 2, the first support 200 comprises a standpipe 210 and and draws pin 220.The first support column 410 can slide in standpipe 210, and draws the pin 220 can be in order to hold the first support column 410.The second support 300 is to be set up in underframe 100, and it comprises a fixed clamp section 310 and a live splint 320.Live splint 320 fixed clamp section 310 motions relatively, this live splint 320 has a movable holding tank 324, this movable holding tank 324 be in order to fixed clamp section 310 common clamping the second support columns 420.

The above-mentioned execution mode of the present invention provides portable electric system not only can utilize solar panels 600 power supplies, also can further utilize the first support 200 and the second support 300 to adjust the height of the first support column 410 and the second support column 420, to adjust fast, easily the height of solar panels 600.

Fig. 3 illustrates the first support 200 of Fig. 2 and the stereogram of the first support column 410.As shown in the figure, in the part execution mode, the first support 200 can comprise and draws pin fixture 230, and it is a tube wall that is arranged at standpipe 210, position and the direction of motion of drawing pin 220 in order to restriction.For example, draw pin fixture 230 can along the normal direction of standpipe 210 tube walls dorsad standpipe 210 extend, and the pin 220 that draws of part is to be located in draw in pin fixture 230 and be communicated in standpipe 210.

Fig. 4 illustrates the profile of the mode of operation of Fig. 3.As shown in the figure, draw pin fixture 230 to have the pin of drawing cavity 232, its be use for draw pin 220 in drawing pin cavity 232 towards or dorsad the first support column 410 move.In the part execution mode, draw pin 220 to comprise and draw plunger 222, to draw pin screw rod 224 and to draw pin core 226.Drawing pin screw rod 224 to be placed in draws in pin cavity 232.Drawing plunger 222 to be exposed to draws outside pin fixture 230.Drawing pin core 226 is to configure towards standpipe 210.In present embodiment, drawing pin core 226 is the tube walls that wear by standpipe 210, and the user can pull or promote to draw plunger 222, makes to draw pin screw rod 224 to move in drawing pin cavity 232, and then orders about and draw pin core 226 to approach or away from the first support column 410 that inserts in standpipe 210.Accordingly, the first support column 410 can comprise at least one location hole 412, and use for drawing pin core 226 to pass standpipe 210 and insert, thus the function that the first support column 410 is fixed in realization.

Particularly, draw pin screw rod 224 to be placed in and draw in pin cavity 232 and with standpipe 210, the first support column 410 and be haply vertical, in addition, draw pin fixture 230 can further comprise a banking stop 234, pin screw rod 224 and the junction of drawing plunger 222 are drawn in its coating, draw pin screw rod 224 only to move along the normal direction of standpipe 210 tube walls in order to restriction, to prevent drawing pin 220 towards other direction motions.Drawing pin core 226 to have the pin of drawing screw thread 228, and can draw an end of pin screw rod 224 by drawing pin screw thread 228 to be attached to, is to be arranged at the other end that draws pin screw rod 224 and draw plunger 222, and its sectional area is greater than drawing pin screw rod 224, gripping and operation in order to the user.

In the part execution mode, this portable electric system can comprise an elastic parts 240, and it is coating and is drawing pin screw rod 224, promotes to draw pin core 226 to utilize the elastic force potential energy.For example, elastic parts 240 can be (comprise, but be not limited to) spring.

Fig. 5 illustrates the profile of another angle of mode of operation of Fig. 4.As shown in the figure, in this mode of operation, drawing pin core 226 is to be inserted in location hole 412, be subject to the tube wall of standpipe 210 and can't move up and down owing to drawing pin core 226, therefore the first support column 410 also can can't move up and down because location hole 412 is subject to drawing the restriction of pin core 226, thus the function that the first support column 410 is fixed in realization.

Fig. 6 illustrates the profile of another mode of operation of Fig. 3.Fig. 7 illustrates the profile of another angle of mode of operation of Fig. 6.The modular construction of this two figure is similar to shown in the 4th and 5 figure, and main difference is that drawing the pin core 226 that draws of pin 220 is the surfaces that prop up the first support column 410, and without inserting in location hole 412.As shown in the figure, when an end that draws pin core 226 is the surface that props up the first support column 410, the other end that elastic parts 240 can be drawn pin core 226 with draw a chamber wall of pin cavity 232 to compress, and hold, the elastic force potential energy is arranged.At this moment, be not subject to drawing the restriction of pin core 226 due to the location hole 412 of the first support column 410, therefore when the user applies certain strength and overcomes the maximum static friction force that draws between pin core 226 and the first support column 410 surfaces, can order about the first support column 410 and move up and down, thus the function that realizes regulating height.

When the first support column 410 is moved into location hole 412 and draws pin core 226 overlapping, owing to drawing pin core 226 will no longer prop up the surface of the first support column 410, therefore ordering about, the elastic force potential energy that has that elastic parts 240 holds draw pin core 226 to move towards location hole 412, and then insert in location hole 412, with the function (as Fig. 4 and shown in Figure 5) that realizes fixing the first support column 410.
