The second latching mechanism 64 includes a second receiving slot. 641 and a second fastening member 642, the second fastening member 642 is disposed in the second receiving groove 641; the principle of the virtual image imaging of the amplification module 6 is imaging through a concave mirror, and the concave mirror imaging formula is 1/p+ 1/q=1/f (f denotes the focal length, q denotes the object distance, p denotes the image distance), the general magnification can enlarge the virtual image, or the same ratio can make the virtual image distance become farther, and the ideal state is about four times to six. Between the times, the user can achieve the best visual state, but the magnification is too large, which is easy for the user to feel dizzy. It is better to make the virtual image reach more than one meter away from the user's eye E. The imaging needs to be about 1 meter in front of the magnifying sheet 61, and the magnifying sheet 61 receives the reflected image of the reflective sheet 51, and displays The at least one bracket 7 includes a frame 71, a first rotating shaft set 72 and a second rotating shaft set 73. The first rotating shaft set 72 is disposed at one end of the frame 71, and the first rotating shaft is disposed. The group 72 includes a first rotating shaft 721 and a first torsion spring S1. The first rotating shaft 721 is inserted into the first torsion spring S1 and pivoted to the first shaft hole 521 of the first pivoting seat 52. A torsion spring S1 provides an upward elastic force to rotate the reflection module 5 upward. The second shaft assembly 73 is disposed at the other end of the frame 71. The second shaft assembly 73 includes a shaft hole seat 731 and a second shaft. 732 and a second torsion spring S2, the shaft hole 731 is provided with a shaft hole 733 and a second limiting slot 734. The second shaft 732 passes through the shaft hole 733 and the second torsion spring S2. The second shaft hole 631 of the second pivoting seat 63 and the through hole 423 of the fixing base 4, the second torsion spring S2 provides an upward elastic force to flip the amplifying module 6 and the bracket 7 upward; The feature is that when the back cover 62 of the amplification module 6 and the bracket 7 are turned over, the same axis is rotated. The fixed seat 4 is connected to the back cover 62 by the second rotating shaft set 73 to form a casing. The inner space A1 of the casing houses the reflecting module 5.

The fixing component 410 is a magnet, a nano magnet or a suction cup, and the fixing component 410 is used for adsorbing a portable electronic device 8.

The portable electronic device 8 is a smart phone, a tablet computer or an electronic device with a screen display.

The first fastening component 432 of the first fastening mechanism 43 is a magnetic component, a magnetic component or a card slot, and the first fastening mechanism 43 is mounted on the other side of the fixing base 4. A bottom cover 433 is disposed on the bottom of the fixing base 4 corresponding to the position of the first fastening mechanism 43.

The second fastening component 642 of the second fastening mechanism 64 is a magnetic component, a magnetic component or a buckle. When the back cover 62 is covered with the fixing base 4, the second fastening mechanism 64 is correspondingly engaged with the first fastening mechanism 43 for fixing the back cover 62 (as shown in the fourth figure).

The first limiting slot 632 of the second pivoting seat 63 is correspondingly sleeved with the second limiting slot 734 of the second rotating shaft set 73, so that the back cover 62 is turned up to a preset position. The bracket 7 can be engaged and rotated for rotation.

The fixing base 4 is connected to the back cover 62 and the bracket 7 by the second rotating shaft set 73 to form a casing.

The bottom of the fixed seat 4 is pivotally connected to the pivot 441 at one end of the tripod 44. The stand 44 can adjust the supporting angle of the fixing seat 4 according to the use requirement, so that the user can see at an optimal viewing angle. An image that is magnified in the air after imaging.

As shown in the sixth to eighth embodiments, the present invention is illustrated by the operation of the cover state (as shown in FIG. 6) to the viewing position. The operation is performed by first pressing the back cover 62 of the amplifying module 6 with a finger. The back cover 62 can be easily opened (as shown in the seventh figure), because the upturning force is far greater than the force of the second fastening mechanism 64 and the first fastening mechanism 43. 62 is no longer engaged, so that the second torsion spring S2 can flip the back cover 62 upward by its elastic force. When the vehicle is turned to the preset position (for example, when it is turned to an angle of 45 degrees), the first limit slot 632 The side of the second limiting slot 734 is just caught (as shown in FIG. 9). At this time, the elastic force of the second torsion spring S2 synchronously drives the bracket 7 to rotate upward, and the reflective sheet 51 follows The rotational displacement of the bracket 7 and the elastic force of the first torsion spring S1 reverse the reflective sheet 51 to the deployed position (as shown in the eighth figure).

When the invention is folded, the back cover 62 is first pressed with a finger, and when the position is changed to a preset position (for example, when the angle is changed to 45 degrees), the first limit missing slot 632 and the second limit missing slot When the 734 engagement state is released, the reflection module 5 is condensed with the rotation of the bracket 7, and the first torsion spring S1 and the second torsion spring S2 are in a compressed state, and the back cover 62 is turned over to the fold. In the position (as shown in the fourth figure), the second fastening mechanism 64 is just engaged with the first fastening mechanism 43. The fixing base 4 connects the back cover 62 and the bracket 7 with the second rotating shaft set 73. A box body is formed, and the box inner space A1 can accommodate the reflection module 5.

FIG. 10 is a schematic diagram of an optical path according to an embodiment of the present invention, wherein an image on the screen of the portable electronic device 8 passes through the reflected light path L1 of the reflective sheet 51, so that the user's eye E can pass through the enlarged sheet. 61 receives the reflected image of the reflective sheet 51, and through the enlarged optical path L2, the user can see the enlarged image of the distant imaging area E1.

In summary, the virtual display device of the present invention utilizes a fixing base to connect a back cover with a second rotating shaft set, and the bracket forms a box body, and the inner space of the box body can conveniently accommodate the reflective sheet, and can be deployed after being deployed. Directly magnifying the image, so that the lack of the formula can be effectively solved, and the technical means used thereof are not available in the prior art, so the novelty and progress of the patent of the present invention are unique. Sexual elements.

The specific embodiments of the present invention are provided to facilitate the description of the technical content of the present invention, and the present invention is not limited to the above embodiments, and the patent application without departing from the spirit of the present invention In the case of a range, various changes are made and still fall within the scope of the invention.
