Specific embodiment

It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched The embodiment stated is the utility model one end point embodiment, rather than the embodiment held entirely.Based on the implementation in the utility model Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to The range of the utility model protection.

As depicted in figs. 1 and 2 is a kind of convenient for projected keyboard that is fixed and carrying, and projected keyboard includes shell 1, shell 1 Front side surface is equipped with infrared projection port 2, sensor 3 and charge port 4, further includes fixed device and portable unit, fixed device packet Baffle 7, frame plate 8, limit shaft 10, connecting rod 12 and damping block 13 are included, 1 left and right sides surface of shell is provided with accommodating groove, and accommodating groove is left Right side wall is provided with sliding slot, and the length of sliding slot 14 is less than the length of accommodating groove 11, as shown in figure 4, sliding slot 14 is rectangular channel, it is sliding Limit shaft 10 is slidably socketed in slot, and limit shaft 10 and the side wall of sliding slot 14 are tangent, rotation is socketed with frame on limit shaft 10 Plate 8,11 liang of side bottoms of accommodating groove are fixed with damping block 13, as shown in figure 5,12 one end of connecting rod and damping block 13 and rotating hinge It connects, the other end and frame plate 8 rotate hingedly, and herein, damping block 13 is made of rubber material, and the fit system with connecting rod 12 is Interference fit, it is therefore an objective to make the rotation of connecting rod 12 that there is damping effect using the elastic deformation of rubber, connecting rod 12 can be rotated It is then static to any position, the gravity due to frame plate 8 can be prevented, and lead to the loosening of entire link mechanism, in addition frame plate 8 On be fixed with pulling buckle 9, pulling buckle 9 can provide the impetus of finger, pull open frame plate 8 convenient for finger, the rotation of 1 liang of lateral roof of shell Equipped with the second shaft, baffle 7 is fixed in the second shaft, the purpose of baffle 7 is when frame plate 8 is completely hidden in accommodating groove 11 When, limitation frame plate 8 moves outside, further, in order to facilitate finger flap shutter 7, baffle 7 should be shaped to L shape；Just Taking device includes shaft 5 and finger ring 6, and rotation is equipped with shaft 5 at the top of shell 1, and the rotation of finger ring 6 is socketed in shaft 5.

As shown in figure 3, accommodating groove 11 is rectangular channel, frame plate 8 is rectangular slab, and the length of accommodating groove is greater than the length of frame plate 8, The depth of accommodating groove is equal to the thickness of frame plate 8, when frame plate 8 is completely hidden in accommodating groove 11, the inner surface and receipts of frame plate 8 Receive slot 11 inner surface contact, it is therefore an objective to the flatness for keeping 1 outer surface of shell enhances whole aesthetics.

The course of work of the utility model is as follows: what is utilized due to projected keyboard is a kind of 3D ETP technology, this technology Principle be that projection element is first projected out keyboard, while launching infrared ray, when the keyboard symbol that finger down projects, Infrared ray can be blocked, a reflection signal is caused, at this moment perceptron will perceive the opposite keyboard coordinate of reflection signal, so Projected keyboard is usually placed in plane and uses, and in use, is easy to be knocked over, in order to increase the firm of projected keyboard Property, it prevents from surprisingly toppling over, needs relevant fixation, when in use, first flap shutter 7, then finger catches hold of pulling buckle 9 outward Mobile, since pulling buckle 9 is fixedly connected with frame plate 8, frame plate 8 under the effect of external force, can move outward, frame plate 8 and connecting rod 12 rotations hingedly bear the gravity of frame plate 8 mainly by connecting rod 12, due to being provided with damping block 133 in accommodating groove 11, Damping block 13 and connecting rod 12 are interference fit, therefore, biggish frictional force can be generated between damping block 13 and connecting rod 12, is acted on On connecting rod 12, so that the gravity of frame plate 8 is balanced out, so that connecting rod 12 is provided with the ability stopped at an arbitrary position, frame plate 8 A triangular structure is together constituted with shell 1, desktop, greatly enhances the stability of projected keyboard；In addition on shell 1 Provided with finger ring 6, shaft 5 and shell 2 are rotation connection, and finger ring 6 and shaft 5 are rotation connection, the combination of the two, so that finger ring 6 are provided with very big angle adjusting range, facilitate the carrying of projected keyboard.

Above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although referring to aforementioned reality Example is applied the utility model is described in detail, those skilled in the art should understand that: it still can be to preceding Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features；And these It modifies or replaces, the spirit and model of various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution It encloses.
