Embodiment
As depicted in figs. 1 and 2, main frame automatic door mechanism of the present utility model comprises door 5, frame 9, sliding support 12, limiting bracket 10, rack slide 2, slide block 11, extension spring 6, DC speed-reducing 4, gear 3, travel switch 1,7 and control circuit board 8, wherein the outside surface of door 5 and computer cabinet front panel outer surface are in same plane, and other structures of automatically-controlled door then are positioned at computer cabinet.Interface panels such as the USB of computing machine, Memory Stick are positioned at the back (interface panel is in the back of computer cabinet front panel) of door 5, are just sheltered from by door 5.Direction when mentioning part assembly relation and motion all refers to the view directions among Fig. 1 below.
As Fig. 3, illustrated in figures 1 and 2, frame 9 is support frames of automatically-controlled door, and four threaded hole 9d are arranged on the frame 9, and by four screws, frame 9 is fixed on computer cabinet front panel back.DC speed-reducing 4 is screwed on the electric machine support 9c of frame 9.Gear 3 is connected on the output shaft of motor 4.Control circuit board 8 is screwed on frame 9.Travel switch 1 and 7 is by the two ends of screw retention in frame 9.Respectively there are two guide rail 9b frame 9 both sides, and rack slide 2 and slide block 11 can be respectively horizontally slip along the guide rail 9b of frame both sides.In addition, a block 9a is arranged on the frame, can limit the horizontally slipping of sliding support 12 of its front.
To shown in Figure 7, is tooth bar 2a as Fig. 4 above the rack slide 2, and it and gear 3 form engaged transmission.A strip chute 2b is arranged below the rack slide 2.The similar of slide block 11 and rack slide 2 has a same strip chute below, does not have tooth bar above just.Rack slide 2, slide block 11 are bonded and fixed at the biside plate 12c outside surface of sliding support 12 respectively, thereby rack slide 2, slide block 11 and sliding support 12 form an integral body, and they are positioned at the front (assembly relation is seen Fig. 1) of frame 9.Rack slide 2, slide block 11, just drive sliding support 12 simultaneously and horizontally slip along frame 9 when the guide rail 9b of frame 9 both sides horizontally slips by chute 2b.
A tilting Z-shaped guide groove 12a is arranged respectively on the upper and lower side plate 12c of sliding support 12, and two screens cylinder 5a of door 5 are stuck among these two guide groove 12a, can slide along guide groove 12a.On the upper and lower side plate 12c of sliding support 12 a block 12b is arranged respectively.Limiting bracket 10 is positioned at the front (assembly relation is seen Fig. 1) of sliding support 12.
Limiting bracket 10 is positioned at the front (assembling relationship figure is seen Fig. 1) of sliding support 12.Sliding tray 10c by two ends can horizontally slip on sliding support 12 along the upper and lower plate 12c of sliding support 12.Two side handle 5b of door 5 are stuck among two stopper slot 10a of limiting bracket 10, and two screens cylinder 5a of door 5 correspondingly are stuck among two guide groove 12a of sliding support 12 side plates, and its assembly relation is seen Fig. 1.Like this, because the constraint of stopper slot 10a, with respect to limiting bracket 10, relative motion before and after door 5 can only have can not have left and right sides relative motion.And the front and back relative motion of door 5 can only be moved along the guide groove 12a of sliding support 12.The two ends of extension spring 6 are separately fixed on the spring hitch 10b and 12d of limiting bracket 10 and sliding support 12, and extension spring 6 can retrain limiting bracket 10 horizontally slipping on sliding support 12.
When motor 4 rotatings, the engaged transmission of gear 3 and tooth bar 2a drives rack slide 2 and horizontally slips on frame 9 along the guide rail 9b on the frame 9.Because rack slide 2 and sliding support 12 are bonded and fixed at together, therefore correspondingly sliding support 12 horizontally slips on frame 9.That is to say that motor positive and inverse can drive sliding support 12 and horizontally slip on frame 9.
Figure 1 shows that the position that door is closed fully, introduce the process that door is opened automatically and closed below by Fig. 1.
The process of opening the door is as follows: motor 4 is just changeing, and drives sliding support 12 and slides left along frame 9.Limiting bracket 10 does not move on left and right directions under the effect of extension spring 6.Under the constraint of limiting bracket 10, door 5 does not have relative motion yet on left and right directions.So at sliding support 12 under the effect of left movement, door 5 guide groove 12a vertically travel forward (from visual angle, the positive front of computer cabinet, i.e. the visual angle of Fig. 2, door vertically withdrawal backward this moment) along sliding support 12.When door 5 vertical when the front moves to the top of guide groove 12a, promptly door 5 is after vertical withdrawal is avoided case front panel fully in cabinet, block 12b on the sliding support 12 runs into limiting bracket 10, so under the thrust of block 12b, sliding support 12 drive limiting brackets 10 and door 5 are together to left movement, and door 5 begins to open.After sliding support 12 ran to high order end, runs into travel switch 1, circuit disconnected, and door 5 is along with sliding support 12 stop motions, and door 5 is opened fully at this moment, and interfaces such as the USB on the main frame, Memory Stick expose fully.
The process of closing the door is as follows: motor 4 counter-rotatings drive sliding support 12 and slide to the right.Sliding support 12 carries limiting bracket 10 and door 5 moves right together, and door 5 begins to close.When running to interface dead ahead such as USB, Memory Stick when door 5, limiting bracket 10 is hindered by the block 9a on the frame 9 and stops.Because sliding support 12 continues operation to the right, so under the effect of the guide groove 12a of sliding support 12, door 5 vertically moves backward (from visual angle, the positive front of computer cabinet, it is the visual angle of Fig. 2, door vertically ejects forward for 5 this moments), run into the travel switch 7 of low order end up to sliding support 12, circuit disconnects, motor 4 stops, the outside surface of door 5 and computer cabinet front panel outside surface are at grade at this moment, door 5 is closed fully, and interfaces such as the USB on the main frame, Memory Stick are sheltered from fully.
As shown in Figure 8, in DLC (digital logic circuit), Q and the Q ' of trigger 74F74 provide control signal, and 0,1 expression is just changeed, 1,0 expression counter-rotating.SWL and SWR are respectively two travel switches of automatically-controlled door, and they are in normally off.When the driven by motor automatically-controlled door runs to left margin or right margin, all can trigger SWL or SWR and disconnect, make node R EVERSE become electronegative potential, thereby triode Q0 lose base current and ends, whole VCC network loses power supply.If press the button switch S N, node R EVERSE is drawn high so, the Q0 conducting, and the VCC network obtains power supply, and trigger 74F74 obtains positive pulse simultaneously, and in the rising edge upset, it is anti-that Q and Q ' become, the motor backward rotation, automatically-controlled door will move round about.Entire circuit is 5 volts of power supplies.
In the mimic channel that drive to amplify, triode Q2, Q3 and Q6, Q7 have constituted H type mode bipolar reversible power driving circuit as shown in Figure 9, and the M1 of driving circuit and M2 node are connected the two poles of the earth of motor respectively.This driving circuit is by the VCC of DLC (digital logic circuit) power supply, and control signal is then from Q and the Q ' node of trigger 74F74 in the digital circuit.Q1, Q4 constitute not circuit, and Q2, the Q3 of same brachium pontis carried out the dead band protection; Q5, Q8 constitute not circuit, and Q6, the Q7 of same brachium pontis carried out the dead band protection; All triodes are all selected the C1815 type for use.Four diodes shield, and prevent that the inverse current that produces when motor positive and inverse switches from impacting.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
