Abstract
The utility model provides a transverse linear motor. The transverse linear motor comprises first magnetic steel, second magnetic steel, a first coil and a second coil. The first magnetic steel and the second magnetic steel are opposite left and right, and the first coil and the second coil are respectively disposed on the upper sides and the lower sides of the first magnetic steel and the second magnetic steel. The transverse linear motor has the advantages of having larger driving force and effectively utilizing designed space.
Description
Technical field
The utility model relates to a kind of horizontal linear motor, relates in particular to a kind of horizontal linear motor that utilizes Electromagnetically actuated principle.
Background technology
In the process of portable communication device fast developments such as mobile phone, more and more higher to the requirement that is installed in electronic devices and components wherein.
The purpose that save the space in order to reach, promotes quality, electronic devices and components progressively develop to extra small ultra-thin direction, thus, as the main implementor of effects such as incoming call prompting, touch-control feedback, the also corresponding quickening of the development of vibrator.Horizontal linear motor in the vibrator has the trend that replaces general vibrator because have stronger advantage on short transverse.Under extra small ultra-thin direction development trend, also more and more higher to the requirement of horizontal linear motor vibrations amount at horizontal linear motor, this has proposed stern challenge to existing vibratory output Design Mode.
Usually the enhancing of unicoil vibratory output all is to adopt increase coil thickness and increasing magnet steel grade to realize, but this mode can reduce the duty ratio of coil, simultaneously also extra small ultra-thin unfavorable to horizontal linear motor, so under the situation that vibratory output is had relatively high expectations, this mode can not satisfy the requirement that improves day by day.
Seeing also Fig. 1, is a kind of generalized section of horizontal linear motor 1, and described horizontal linear motor 1 comprises an a pair of magnet steel 10 and a coil 12.Please consulting Fig. 2 again, is the schematic cross-section of coil 12 shown in Figure 1, and described coil 12 is the single coiled wire-wound coils that form with circular enamelled wire coiling.
Mainly there is following problem in described horizontal linear motor 1: at first, because described coil 12 is single coiled wire-wound coil, cause the magnetic field of the magnet steel 10 that cooperates with described coil 12 only to have half to be utilized, and also have half to slattern, determined that the actuating force of described horizontal linear motor 1 is less; Secondly, because described coil 12 forms for circular enamelled wire coiling,, wasted the design space so the duty ratio of its coiling is less relatively.
The utility model content
Problems such as the actuating force at existing horizontal linear motor existence is less, waste design space, the utility model provides a kind of actuating force more greatly, effectively to utilize the horizontal linear motor of design space.
A kind of horizontal linear motor, comprise first magnet steel, second magnet steel, first coil and second coil, be oppositely arranged about described first magnet steel and described second magnet steel, described first coil and second coil are separately positioned on the both sides up and down of described first magnet steel and described second magnet steel.
As the further improvement of above-mentioned horizontal linear motor, the copper cash cross section of described first coil and described second coil is the flat structure
As the further improvement of above-mentioned horizontal linear motor, the electrical current direction of described first coil and described second coil is identical, and the magnetizing direction of described first magnet steel and described second magnet steel is opposite.
Compared to prior art, it is the copper cash of flat that the coil of horizontal linear motor of the present utility model has adopted cross section, and the duty ratio of described coil is higher than the coil of prior art, thereby under the identical situation of drive coil resistance, can save the space effectively.Secondly, adopt two coil configuration, and the electrical current direction of described twin coil is identical, can make full use of the double-edged magnetic field of described magnet steel, under the situation that does not increase the oscillating component quality, improved the vibratory output of described horizontal linear motor, increased actuating force.
Description of drawings
Fig. 1 is a kind of generalized section of the horizontal linear motor relevant with the utility model.
Fig. 2 is the loop construction schematic cross-section of horizontal linear motor shown in Figure 1.
Fig. 3 is the generalized section of horizontal linear motor one better embodiment of the utility model.
Fig. 4 is the structures of copper lines schematic cross-section of the coil of horizontal linear motor shown in Figure 3.
Embodiment
Below in conjunction with accompanying drawing horizontal linear motor of the present utility model is described.
Seeing also Fig. 3, is the generalized section of horizontal linear motor one better embodiment of the utility model, and described horizontal linear motor 2 comprises two magnet steel 20 and two coil 22.Described two magnet steel 20 are permanent magnet, and it is made by the higher strong metal of multiple hardness usually, as iron, aluminium, nickel and cobalt etc., and perhaps copper, niobium and tantalum etc., according to the difference of composition, its magnetic property is also to should be differentiated.Described two magnet steel 20 are provided with about being, and its magnetizing direction is opposite, that is, wherein a magnet steel 20 upwards magnetizes, and another magnet steel 20 magnetizes downwards.
Described two coil 22 is separately positioned on the both sides up and down of described two magnet steel 20.Please consulting Fig. 4 again, is the structures of copper lines schematic cross-section of described coil 22.It is the copper cash of flat that described coil 22 has adopted cross section, thus its can be in unit volume the more relatively flat type copper wire of coiling, perhaps satisfying under the situation of performance requirement, reduce the volume that described coil 22 takies.So the copper cash duty ratio of described coil 22 has obtained effective raising, can correspondingly effectively improve actuating force.
Further, the electrical current direction of described two coil 22 is identical, can make full use of described two magnet steel 20 double-edged magnetic fields like this, further improves actuating force.
Compared to the horizontal linear motor of the unicoil of prior art, it is the coil 22 of flat that horizontal linear motor 2 of the present utility model has adopted cross section, so the copper cash duty ratio of described coil 22 is higher, thereby, can save the design space effectively driving under the identical situation of described coil 22 resistance.Secondly, horizontal linear motor 2 of the present utility model has adopted twin coil 22 structures, and the electrical current direction of described two coil 22 is identical, can make full use of described two magnet steel 20 double-edged magnetic fields, under the situation that does not increase the oscillating component quality, improved the vibratory output of described horizontal linear motor 2.
Only be preferred case study on implementation of the present utility model below, be not limited to the utility model, for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
