Abstract
The utility model discloses an electromagnetic structure for taking a mobile phone off a display frame. The electromagnetic structure comprises a bottom box fixed on the display frame and an upper box connected with the mobile phone, wherein the lower box is equipped with an embedding groove, a magnet and a magnetic conductive iron sheet, the upper box is equipped with a projection corresponding with the embedding groove, and an iron sheet is embedded into the surface of the upper box by a mold inserting technology. When the upper box is placed on the lower box, the projection is embedded into the embedding groove. A tongue tube is arranged in the upper box, wherein the tongue tube is used for counting take-off times. The electromagnetic structure for taking the mobile phone off the display frame has the following advantages that the upper and lower boxes with magnetic and magnetic conductive medium are used to meet requirements of decreasing gaps and possessing stronger attracting forces; the tongue tube can count opening and closing times; and fewer magnets are used, so that the device is low in the cost and simpler in the technology.
Description
[technical field]
The utility model relates to the Mobile phone burglar alarm field, especially a kind of electromagnetic structure for mobile phone Display Rack off-hook.
[background technology]
What the existing employed machine back pass of Mobile phone burglar alarm sensor adopted is by two magnet attractions, so that two end faces of box are adjacent to about the machine back pass sensor.Need for guaranteeing to install, need guarantee at least the thickness of two plastic casings between two adhesive faces of the upper lower magnet of this structure, cause magnetic to descend, reliability is not high.
In the prior art, box is to inhale mutually so that two end faces of upper box and lower box are adjacent to by two blocks of magnet with lower box on the machine back pass sensor, owing in the box magnet is housed all up and down, the tongue tube of therefore can not packing into can not be added up the off-hook number of times.And because magnet itself is more crisp, can only be manual viscose glue install, comparatively time-consuming and cause easily waste.
[utility model content]
The purpose of this utility model is to provide a kind of and can improve adsorption effect for the deficiency of the above prior art existence, reduces the slit, and has the electromagnetic structure that is used for mobile phone Display Rack off-hook of off-hook statistical counting function.
To achieve these goals, the utility model is achieved in that the electromagnetic structure for mobile phone Display Rack off-hook, it comprises for fixing to the lower box on the Display Rack and the upper box that is connected being connected with mobile phone, described lower box is provided with caulking groove, described upper box is provided with the projection corresponding with described caulking groove, is provided with magnet in the described lower box, and is provided with iron plate in the described upper box, when upper box was placed on the described lower box, described projection embedded in the described caulking groove.Described upper box is fixed by the enhancing of the magnet of described lower box.
Described magnet is embedded in the described caulking groove, and described iron plate adopts mold insert technique to embed in the lug surface.
Also be provided with magnetic conductive iron sheet in the described caulking groove, to improve the magnetic conduction effect; Iron plate in the described projection closely inhales upper box and lower box with the interior magnet of caulking groove by two magnetic conductive iron sheets mutually, reaches not have apertured best adhesive effect.
In the described upper box tongue tube is set, is used for realizing up and down box deciliter detection in conjunction with response circuit; When box adhesive up and down, the magnet magnetization iron plate, with magnetic fields in tongue tube, so that tongue tube is closed; When box separated up and down, upper box lost magnetic field, and tongue tube disconnects.In conjunction with the circuit of response, this structure is used for statistics off-hook number of times.
Compared with prior art, the utility model has the following advantages: reach the minimum slit that cooperates by the magnetic up and down box structure of above-described one group of tool, reach the best effect of closing by force; Can realize statistics to opening/closing frequency by described tongue tube combined circuit; And can reduce the use of magnet, it is low to make device have a cost, and technique is simpler.

[embodiment]
Below in conjunction with the drawings and specific embodiments the utility model is described in detail explanation.
The electromagnetic structure that is used for mobile phone Display Rack off-hook, as Figure 1-3, it comprises for fixing to the lower box 1 on the Display Rack 3 and the upper box 2 that is connected being connected with mobile phone, described lower box 1 is provided with caulking groove 11, described upper box 2 is provided with the projection 21 corresponding with described caulking groove 11, be provided with magnet 12 in the described lower box 1, and described upper box 2 interior employing mold insert techniques embeds iron plates 23, when upper box 2 was placed on the described lower box 1, described projection 21 embedded in the described caulking groove 11.Described upper box 2 is fixed by the enhancing of the magnet of described lower box 1.Described magnet 12 is embedded in the described caulking groove 11, and described iron plate 23 is embedded in the projection 21; It is tightr to play the effect that reduces the slit that described projection 21 and caulking groove 11 inhale upper box and lower box by electromagnetic field mutually.Also be provided with magnetic conductive iron sheet in the described caulking groove 11, to improve the magnetic conduction effect; Iron plate 23 in the described projection 21 closely inhales upper box and lower box with caulking groove 11 interior magnet 12 by two magnetic conductive iron sheets mutually, reaches not have apertured best adhesive effect.
In order to realize the statistics to the off-hook number of times, the described upper box 2 interior tongue tubes 22 that arrange, when box adhesive up and down, the magnet magnetization iron plate, with magnetic fields in tongue tube 22, so that tongue tube 22 closures; When box separated up and down, upper box lost magnetic field, and tongue tube disconnects.In conjunction with the circuit of response, this structure is used for statistics off-hook number of times.As shown in Figure 4, tongue tube 22 is selected normal opened contact (H) type, opens at ordinary times, and when only having reed to be magnetized, contact just contacts; So form a change over switch: when the magnetic field that permanent magnet forms near tongue tube or the coil electricity on tongue tube makes the reed magnetization, the contact part of reed will be by magnetic attraction, when attraction during greater than the elastic force of reed, normal opened contact will adhesive; When magnetic force was reduced to a certain degree, contact was opened by the elastic force of reed.The tongue tube of in the upper box of the machine back pass sensor of Display Rack 1, packing into, by the electromagnetic activity in the box moving process up and down so that the tongue tube closure to reach the purpose of counting.
The utility model is provided with magnet by the depressed part of inlaying iron plate and lower box as the lug boss of the upper box of machine back pass sensor and consists of a kind of electromagnetic structure.Upper box lug boss directly is embedded in the plastic box iron plate so that processing technology is simpler by the mold insert technology, reduces the waste to magnet.Because lower tape is magnetic, and upper box does not have magnetic, tongue tube can be inserted in the upper box simultaneously, the electromagnetism that the opening and closing movement by upper box and lower box produces makes tongue tube closed, reaches the purpose of counting.
Although the utility model is to describe with reference to specific embodiment, this description and not meaning that is construed as limiting the utility model.With reference to description of the present utility model, other of the disclosed embodiments change, and all can expect for those skilled in the art, and this variation should belong in the affiliated claim limited range.
