6, first support 9 is fixed on the balladeur train 1;
7, balladeur train 1 is socketed on the column 2;
8, the column 2 and second support 3 is fixing;
9, second support 3 is fixed on the body of wall, guarantees that tooth bar 6 is meshed with gear 5.
The working procedure and the principle of the utility model hanger are following:
In the present embodiment, when the user need heighten the height of display screen, just changeing with motor 4 was to heighten display screen, and motor 4 counter-rotating is that to turn down display screen be the example explanation.Through the button on the remote controller; Key operation on the wireless receiving module response remote controller in the circuit board 10; Motor 4 starts; Actuation gear 5 rotates, and is being with balladeur train 1 to move upward along column 2 with the tooth bar 6 of gear 5 engagements, and drive reaches the display screens of fixing with first support 9 with the balladeur train 1 first fixing support 9 and moves upward.When display screen moved to suitable height, the button on the remote controller made motor 4 outage, and the electric current moment of this moment through the electromagnet 73 of self-locking mechanism 7 diminishes; Electric current through this electromagnet 73 produces electromagnetic induction because of instantaneous variation, so electromagnet generation magnetic, according to right-hand[ed; Judge the magnetic of this electromagnet 73, and the magnetic of electromagnet 73 and opposite with the magnetic of magnetic patch 722, so the two attracts each other; Because electromagnet 73 is fixed in the tooth bar pawl lid 74, and magnetic patch 722 is arranged on the tooth bar pawl 72, and tooth bar pawl 72 can be done in chute 71 and slides up and down; So magnetic patch 722 moves upward, and move upward, with reference to Figure 16 with the ratchet 721 of magnetic patch 722 one; Be the schematic representation of ratchet lock gear among the utility model embodiment, ratchet 721 moves to the position of lock gear 5, stops gear 5 to do reversing motion; Can prevent that said display screen and driven subassembly from because of moving downward under the self gravitation effect, so just having reached the purpose of self-locking.When lower position switch 64 touched second support 8, promptly display screen moved to the extreme higher position that is allowed, motor 4 outage, this moment self-locking mechanism 7 electromagnet 73 dead electricity, and then reach the purpose of self-locking equally.
When the user need turn down the height of display screen, through the button on the remote controller, the key operation on the wireless receiving module response remote controller in the circuit board 10; At first electromagnet 73 obtains immediate current, and this immediate current produces the magnetic force that repels mutually with magnetic patch 722, and (its principle is: the electric current moment change through said electromagnet 73 is big, and this immediate current produces magnetic; According to right hand rule, the magnetic pole of this generation is identical with the polarity of magnetic patch 722, therefore repels each other with this magnetic patch 722); Make this electromagnet and magnetic patch 722 repel each other; And then make the ratchet 721 with magnetic patch 722 one move downward, with reference to Figure 17, be the schematic representation of ratchet release gear among the utility model embodiment; Ratchet 721 moves to the position that discharges gear 5, has so just reached the purpose of removing self-locking.This moment motor 4 electric startup counter-rotating, actuation gear 5 rotates, and is being with balladeur train 1 to move downward along column 2 with the tooth bar 6 of gear 5 engagements, moves downward with fixing first support 9 of balladeur train 1 and with first support, 9 fixing display screens.When display screen moved to suitable height, the button on the remote controller made motor 4 outage, and the electric current moment of this moment through the electromagnet 73 of self-locking mechanism 7 diminishes; According to right-hand[ed, this electromagnet 73 is opposite with the polarity of magnetic patch 722, so electromagnet 73 attracts each other with magnetic patch 722; Because electromagnet 73 is fixed in the tooth bar pawl lid 74, and magnetic patch 722 is arranged on the tooth bar pawl 72, and tooth bar pawl 72 can be done in chute 71 and slides up and down; So magnetic patch 722 moves upward, promptly the ratchet 721 with magnetic patch 722 one moves upward, with reference to Figure 16; Be the schematic representation of ratchet lock gear among the utility model embodiment, ratchet 721 moves to the position of lock gear 5, stops gear 5 to do reversing motion; Can prevent that said display screen and driven subassembly from because of moving downward under the self gravitation effect, so just having formed self-locking.When upper limit position switch 63 touched second support 8, promptly display screen moved to the extreme lower position that is allowed, motor 4 outages, the self-locking of electromagnet 73 dead electricity (principle is the same, repeats no more here) of self-locking mechanism 7, and then realization at this moment.
The utility model drives balladeur train 1 through drive unit 300 and moves along guiding device 200; Moving up and down of the display screen of having realized being connected with balladeur train 1; Can be according to the height of user's request free adjustment display screen; Guaranteed that the user can look squarely the content of seeing in the screen, brought convenience, strengthened user's experience effect to the user.
More than be merely the preferred embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
