[0031] Please refer to Figure 1 The present embodiment provides a resolution amplification device 100, including a base 110, an FPC board, a hollow elastic member 130 and an optical glass 140. The FPC board is arranged on the base 110. A light inlet 111 penetrating through two opposite sides of the base 110 is arranged in the middle of the base 110, and a first limiting column 112 is arranged on the periphery of the light inlet 111; a first positioning hole 131 corresponding to the first limiting column 112 is arranged on the elastic member 130, and the elastic member 130 is clamped with the base 110 through the first positioning hole 131, so that the hollow part of the elastic member 130 is coaxially arranged with the light inlet 111, and the optical glass 140 is arranged in the hollow part of the elastic member 130 to cover the light inlet 111; the FPC board 120 can drive the elastic member 130 to move along the first direction a and the second direction b on the board surface, respectively, and the first direction a and the second direction b are perpendicular to each other.

[0032] Specifically, the present application provides a resolution amplification device 100, which includes a base 110, wherein a light inlet 111 penetrating two opposite sides of the base 110 is provided in the middle of the base 110, and the light inlet 111 is used to inject a light beam; and further includes an elastic member 130, wherein the elastic member 130 is a hollow structure, and the elastic member 130 can be connected to the surface of the base 110 so that the hollow part thereof is coaxially arranged with the light inlet 111; an optical glass 140 is provided on the elastic member 130, and the optical glass 140 is provided in the hollow part of the elastic member 130 to cover the hollow part of the elastic member 130 and the light inlet 111. The light beam can be injected into the optical glass 140 from the light inlet 111 and ejected to form an image. An FPC board is provided on the base 110, and the FPC board can drive the elastic member 130 to move in a first direction a and a second direction b on the board surface, respectively, wherein the first direction a and the second direction b are perpendicular to each other, so as to improve the imaging resolution through high-frequency movement.

[0033] In order to save the required space of the resolution amplification device 100 and reduce the thickness of the board without affecting the connection stability of the resolution amplification device 100, the elastic member 130 is embedded in the surface of the base 110 by a snap-on connection method. A first limiting column 112 is also provided on the side of the base 110 facing the elastic member 130, and the first limiting column 112 is provided at the periphery of the light inlet 111; correspondingly, a first positioning hole 131 is penetrated through the board surface of the elastic member 130, and the first positioning hole 131 corresponds to the position of the first limiting column 112. The elastic member 130 can be snapped with the first limiting column 112 of the base 110 through the first positioning hole 131, and then embedded in the base 110 as a whole. After the first limiting column 112 is snapped with the first positioning hole 131, the first limiting column 112 and the first positioning hole 131 can be further fixed by dispensing glue.

[0034] It should be noted that, first, the first limiting column 112 includes multiple first limiting columns 112, which are evenly distributed at the four corners of the periphery of the light entrance 111 of the base 110; the first positioning hole 131 includes multiple first limiting columns 112, which are evenly distributed at the four corners of the hollow part of the elastic member 130, so as to correspond one-to-one with the first limiting columns 112.

[0035] Specifically, Figure 2 and Figure 3As shown, the first limiting posts 112 include a plurality of first limiting posts 112, preferably, four first limiting posts 112 are provided, and are evenly distributed at the four corners of the periphery of the light entrance 111 of the base 110; correspondingly, the first limiting posts 112 are evenly distributed at the four corners of the hollow portion of the elastic member 130, and the number and the setting positions of the first positioning holes 131 correspond one to one with the first limiting posts 112. Through such a setting, the force points connected between the elastic member 130 and the base 110 are made more uniform, and the reliability and stability of the elastic member 130 driving the optical glass 140 to vibrate at high frequencies are improved.

[0036] Second, if Figure 3 As shown, bosses 113 are provided at four corners of the periphery of the light entrance 111 of the base 110 , and the first limiting column is disposed on the bosses 113 .

[0037] Specifically, bosses 113 are provided at the four corners of the periphery of the light inlet 111 of the base 110, so that the base 110 has a stepped structure with different heights, and the first limiting column is provided on the boss 113. Through such a setting, after the base 110 is connected to the elastic member 130, there is a partial gap between the elastic member 130 and the base 110, so that the remaining components can be arranged at the gap, further improving the space utilization of the resolution amplification device 100, saving the required space of the resolution amplification device 100, reducing the plate thickness, and improving the applicability of the resolution amplification device 100.

[0038] The resolution amplification device 100 provided in the present application includes a base 110, an FPC board, a hollow elastic member 130 and an optical glass 140. The FPC board is arranged on the base 110. A light inlet 111 penetrating through two opposite sides of the base 110 is arranged in the middle of the base 110. A first limiting column 112 is arranged on the periphery of the light inlet 111. A first positioning hole 131 corresponding to the first limiting column 112 is arranged on the elastic member 130. The elastic member 130 is connected to the base 110 through the first positioning hole 131. The hollow part of the elastic member 130 is snap-fitted so that it is coaxially arranged with the light inlet 111. The snap-fitting and embedding connection between the first positioning hole 131 and the first limiting column 112 can effectively save the required space of the resolution amplification device 100 and reduce the thickness of the board. The optical glass 140 is arranged in the hollow part of the elastic member 130 to cover the light inlet 111. The FPC board can drive the elastic member 130 to move along the first direction a and the second direction b on the board surface, respectively, and the first direction a and the second direction b are perpendicular to each other. The resolution amplification device 100 obtained by the above design can effectively save the required space of the resolution amplification device 100 and reduce the thickness of the board through the snap-fitting and embedding connection between the first positioning hole 131 and the first limiting column 112, thereby improving the applicability of the resolution amplification device 100, and at the same time can also improve the precision and stability of the connection of each component.

[0039] In one possible implementation mode of the present application, the base 110 is provided with a second limiting column 114, and the FPC board is provided with a second positioning hole 121 corresponding to the second limiting column 114, and the FPC board is connected to the base 110 through the second positioning hole; the FPC board and the elastic member 130 are arranged side by side on the base 110.

[0040] Specifically, Figure 4 As shown, a second limiting column 114 is also provided on the base 110, and correspondingly, a second positioning hole 121 is provided on the FPC board. The second positioning hole 121 is adapted to the setting position and structural shape of the second limiting column 114. The FPC board is clamped with the second limiting column 114 on the base 110 through the second positioning hole 121, so that the FPC board is fixedly connected to the base 110, and the FPC board and the elastic member 130 are arranged side by side on the base 110.

[0041] Through such an arrangement, the connection stability of the resolution amplification device 100 is improved, and the FPC board and the elastic member 130 are arranged side by side on the base 110, which reduces the board thickness of the resolution amplification device 100 and further improves its applicability.

[0042] In one possible implementation mode of the present application, a plurality of electromagnetic drive components 150 are provided on a side of the base 110 facing the elastic member 130, and the electromagnetic drive components 150 are respectively arranged on opposite sides of the light entrance 111 of the base 110, and are respectively arranged along a first direction a and a second direction b; the two electromagnetic drive components 150 relatively arranged along the first direction a are used to drive the elastic member 130 to move along the first direction a; the two electromagnetic drive components 150 relatively arranged along the second direction b are used to drive the elastic member 130 to move along the second direction b.

[0043] Specifically, Figure 5 As shown, a plurality of electromagnetic drive components 150 are provided on one side of the base 110 facing the elastic member 130. In one embodiment of the present application, the electromagnetic drive components 150 include four, and the four electromagnetic drive components 150 are respectively arranged on opposite sides of the light entrance port 111 of the base 110, that is, an electromagnetic drive component 150 is provided on the upper side, the lower side, the left side and the right side of the plate surface where the light entrance port 111 is located, and the two relatively arranged electromagnetic drive components 150 are arranged along the first direction a or the second direction b.

[0044] The FPC board can drive the two electromagnetic driving components 150 relatively arranged along the first direction a through the electromagnetic driving component 150 to drive the elastic sheet to move at high frequency along the first direction a, thereby driving the optical glass 140 arranged in the hollow part of the elastic member 130 to move at high frequency along the first direction a; similarly, the FPC board can drive the two electromagnetic driving components 150 relatively arranged along the second direction b through the electromagnetic driving component 150 to drive the elastic sheet to move at high frequency along the second direction b, thereby driving the optical glass 140 arranged in the hollow part of the elastic member 130 to move at high frequency along the second direction b.

[0045] By arranging two electromagnetic driving components 150 relatively in the first direction a and the second direction b respectively, the movement of the optical glass 140 along the first direction a and the second direction b is independent. Such a control method is simpler and the control effect is more accurate.

[0046] In another possible implementation of the present application, a plurality of electromagnetic drive components 150 are provided on a side of the base 110 facing the elastic member 130, and the electromagnetic drive components 150 are respectively arranged on two opposite sides of the light entrance 111 along the first direction a and are separately arranged on any side of the light entrance 111 along the second direction b; or, the electromagnetic drive components 150 are respectively arranged on two opposite sides of the light entrance 111 along the second direction b and are separately arranged on any side of the light entrance 111 along the first direction a.

[0047] Specifically, Figure 5 As shown, a plurality of electromagnetic drive components 150 are arranged on one side of the base 110 facing the elastic member 130. In another embodiment of the present application, two electromagnetic drive components 150 are respectively arranged on opposite sides of the light entrance 111 along the first direction a, and are arranged on any side of the light entrance 111 along the second direction b; or, the two electromagnetic drive components 150 are respectively arranged on opposite sides of the light entrance 111 along the second direction b, and are arranged on any side of the light entrance 111 along the first direction a; that is, two electromagnetic drive components 150 are relatively arranged on the upper and lower sides of the plate surface where the light entrance 111 is located, and one electromagnetic drive component 150 is arranged on the left or right side.

[0048] The FPC board can drive one of the electromagnetic driving components 150 along the first direction a through the electromagnetic driving component 150 to drive the elastic sheet to move at high frequency along the first direction a, thereby driving the optical glass 140 disposed in the hollow part of the elastic member 130 to move at high frequency along the first direction a; similarly, the FPC board can drive the electromagnetic driving component 150 separately disposed along the second direction b through the electromagnetic driving component 150 to drive the elastic sheet to move at high frequency along the second direction b, thereby driving the optical glass 140 disposed in the hollow part of the elastic member 130 to move at high frequency along the second direction b.

[0049] Through such an arrangement, the electromagnetic driving assembly 150 arranged along the first direction a and the second direction b can drive the high-frequency movement of the elastic sheet by combined control, which is more controllable and further improves the reliability of the use of the resolution amplification device 100.

[0050] Furthermore, the electromagnetic driving component 150 includes a coil 151 and a magnet 152 , and any electromagnetic driving component 150 is disposed between two adjacent first limiting columns.

[0051] Specifically, the electromagnetic drive assembly 150 includes a coil 151 and a magnet 152. Through the control of the FPC board, a magnetic field that deflects the optical glass 140 can be formed between the coil 151 and the magnet, thereby driving the elastic member 130 and the optical glass 140 to move at high frequency in the first direction a and the second direction b respectively under the action of the magnetic field. Among them, any electromagnetic drive assembly 150 is arranged between two adjacent first limit columns, so that the force points of the elastic member 130 that are subjected to high-frequency movement by the electromagnetic drive assembly 150 are more uniform, thereby improving the reliability and stability of the elastic member 130 driving the optical glass 140 to vibrate at high frequency.

[0052] Furthermore, multiple magnets 152 are distributed around the periphery of the optical glass 140 so as to be disposed between the optical glass 140 and the coil 151. Such an arrangement enables the magnetic field formed between the coil 151 and the magnet to deflect the optical glass 140 to act more reliably on the optical glass 140, thereby further realizing the vibration frequency of the elastic member 130 and the optical glass 140 and improving the resolution of the resolution amplification device 100.

[0053] Furthermore, grooves 115 are disposed on two opposite sides of the light entrance 111 of the base 110 , and the coil 151 is disposed in the grooves 115 .

[0054] Specifically, grooves 115 are provided on opposite sides of the light entrance 111 of the base 110. The grooves 115 and the bosses 113 provided on the base 110 form a stepped structure. The coil 151 is provided in the groove 115, so that there is a certain gap between the upper surface of the coil 151 and the elastic member 130 to prevent the coil 151 from reducing the vibration frequency of the elastic member 130, thereby improving the reliability and stability of the high-frequency vibration process of the elastic member 130; at the same time, such a setting method can also further reduce the plate thickness of the resolution amplification device 100 and improve its applicability.

[0055] Preferably, a third positioning hole 1511 is provided in the middle of the coil 151 , and a limiting portion 1151 matching the third positioning hole 1511 is convexly provided on the groove 115 . The coil 151 is engaged with the limiting portion 1151 through the third positioning hole 1511 to be fixedly connected to the base 110 .

[0056] Specifically, the middle of the coil 151 is provided with a third positioning hole 1511, and correspondingly, the middle of the groove 115 is provided with a stopper 1151, and the setting position and shape structure of the stopper 1151 are adapted to the third positioning hole 1511, and the coil 151 can be clamped on the stopper 1151 through the third positioning hole 1511 to be fixedly connected with the base 110. Such a setting can further improve the stability of the connection between the coil 151 and the base 110.

For those skilled in the art, the utility model can have various modifications and changes.
