Description

Technical Field

[0001] The present application relates to the technical field of optical equipment, and in particular to a diamond pixel expansion device and a projection device. Background Art

[0002] The clarity of the projection image formed by the projection device is positively correlated with the number of pixels that the optical-mechanical components can generate. It is a feasible way to improve the quality of the projection image by increasing the number of pixels that the optical-mechanical components can generate, but this method will greatly increase the cost of the projection device.

[0003] In the related art, a galvanometer is set in the projection device to expand the pixels of the projection screen by using the high-frequency reciprocating motion of the galvanometer, so as to improve the quality of the projection screen. However, such a galvanometer is only suitable for expanding rectangular pixels, but not for expanding diamond pixels. Therefore, a device that can expand diamond pixels is urgently needed. Utility Model Content

[0004] The present application provides a diamond pixel expansion device and a projection device, which can realize the expansion of diamond pixels and help improve the quality of the projection picture.

[0005] On the one hand, the present application provides a diamond pixel expansion device, which includes: a base, a vibration component and a driving component; wherein the vibration component has a bearing portion and at least two elastic portions, the bearing portion is used to mount an optical lens, and the vibration component is mounted on the base through a plurality of elastic portions, and each elastic portion can produce elastic deformation; a plurality of groups of driving components are respectively arranged at different positions between the base and the vibration component; under the drive of the driving component, the vibration component can deflect relative to the base around a first deflection axis and a second deflection axis through a plurality of elastic portions to drive the optical lens to deflect relative to the base, and the first deflection axis and the second deflection axis satisfy a vertical relationship.

[0006] The diamond pixel expansion device provided by the present application has a vibration component installed on the base, and the vibration component is connected to the base through multiple elastic parts on the vibration component, and the elastic parts are set to a structural form that can produce elastic deformation, so that the vibration component can move relative to the base; and a bearing part is set on the vibration component, and the optical lens can be installed on the vibration component through the bearing part. Multiple groups of driving components are set between the base and the vibration component, and the multiple groups of driving components can provide forces to different positions of the vibration component respectively, so that the vibration component can drive the optical lens to deflect relative to the base around the deflection axis.

[0007] At the same time, the vibration component is provided with a first deflection axis and a second deflection axis, and the first deflection axis and the second deflection axis are provided to satisfy a vertical relationship, so that the vibration component can drive the optical lens to reciprocate around the first deflection axis and the second deflection axis relative to the substrate. In this way, the first deflection axis can be made parallel to one symmetry axis of the rhombus pixel, and the second deflection axis can be made parallel to another symmetry axis of the rhombus form. In this way, in the process of the vibration component driving the optical lens to deflect around the first deflection axis and the second deflection axis, after the light beam of the rhombus pixel passes through the reciprocatingly deflected optical lens, the image of the rhombus pixel can appear in four areas respectively within one cycle, and these four areas are located in the four areas above, below, left and right of the rhombus pixel relative to the rhombus pixel, so that a rhombus image point similar to the rhombus pixel but with a larger area than the rhombus pixel can be formed by the rhombus images in the four areas. Therefore, the rhombus pixel expansion device provided in the present application can realize the expansion of the rhombus pixel, which is conducive to improving the quality of the projection picture.

[0008] In one possible implementation of the present application, the diamond pixel expansion device includes four groups of drive components, and in the circumferential direction along the vibration component, two groups of drive components of the four groups of drive components are relatively arranged on both sides of the vibration component along the first deflection axis, and the other two groups of drive components of the four groups of drive components are relatively arranged on the other two sides of the vibration component along the second deflection axis; or, the diamond pixel expansion device includes two groups of drive components, and in the circumferential direction along the vibration component, one group of drive components of the two groups of drive components is arranged on one side of the vibration component along the first deflection axis, and the other group of drive components of the two groups of drive components is arranged on the other side of the vibration component along the second deflection axis.

[0009] In the above embodiment, since four groups of drive assemblies are arranged between the vibration assembly and the base, and the four groups of drive assemblies are distributed along the circumferential direction of the vibration assembly, the four groups of drive assemblies can provide driving force to the bearing part of the vibration assembly from four points; and two groups of drive assemblies among the four groups of drive assemblies are arranged along the first deflection axis, and the other two groups of drive assemblies are arranged along the second deflection axis. Alternatively, two groups of drive assemblies are arranged between the vibration assembly and the base, and the two groups of drive assemblies are arranged on two adjacent sides of the vibration assembly in two directions perpendicular to each other. In this way, by controlling the drive assemblies arranged perpendicularly to each other, the bearing part can generate deflection motion relative to the base around the first deflection axis and the second deflection axis perpendicular to each other.

[0010] In one possible implementation of the present application, under the drive of a driving component arranged along the first deflection axis, the first side of the load-bearing part deflects around the second deflection axis toward the direction close to the base, so that the load-bearing part changes from a balanced posture to a first deflection posture; or, under the drive of a driving component arranged along the second deflection axis, the second side of the load-bearing part deflects around the first deflection axis toward the direction close to the base, so that the load-bearing part changes from the first deflection posture to the second deflection posture; or, under the drive of a driving component arranged along the first deflection axis, the first side of the load-bearing part deflects around the second deflection axis toward the direction away from the base, so that the load-bearing part changes from the second deflection posture to a third deflection posture; or, under the drive of a driving component arranged along the second deflection axis, the second side of the load-bearing part deflects around the second deflection axis toward the direction away from the base, so that the load-bearing part changes from the third deflection posture to a fourth deflection posture; wherein, in the circumferential direction along the vibration component, the first side and the second side are two adjacent sides on the load-bearing part.

[0011] In the above embodiment, since the bearing part of the vibration component can be driven by multiple groups of driving components and can alternately deflect in four directions around the first deflection axis and the second deflection axis relative to the base, the projection light of the diamond pixel can be deflected four times within one cycle through the optical lens installed on the bearing part, and then under the effect of the visual afterimage phenomenon, the diamond pixel can be amplified within one cycle.

[0012] In a possible implementation of the present application, the driving assembly includes corresponding permanent magnets and electromagnetic components, one of which is fixed on a substrate, and the other of which is fixed on a vibration assembly.

[0013] In the above embodiment, since the driving component is configured to include a permanent magnet and an electromagnetic component, the magnitude and direction of the current passed through the electromagnetic coil can be controlled to control the magnetic field strength of the magnetic field generated by the electromagnetic coil, thereby controlling the magnitude and direction of the magnetic force on the permanent magnet. In addition, the magnitude, direction and frequency of the current passed through the electromagnetic coil are easy to control, thereby facilitating the control of the magnitude, direction and frequency of the magnetic force on the permanent magnet.

[0014] In one possible implementation of the present application, the electromagnetic component includes an electromagnetic coil, and the permanent magnetic component includes a magnet. In the circumferential direction of the vibration component, the two electromagnetic coils in the two groups of drive components are electrically connected, and when the two electromagnetic coils are energized, the magnetic fields generated by the two electromagnetic coils are in opposite directions, which are the same as the directions of the magnetic poles of the two magnets corresponding to the two electromagnetic coils; or, in the circumferential direction of the vibration component, the two electromagnetic coils in the two groups of drive components are electrically connected, and when the two electromagnetic coils are energized, the magnetic fields generated by the two electromagnetic coils are in the same direction, which are opposite to the directions of the magnetic poles of the two magnets corresponding to the two electromagnetic coils.

[0015] In the above embodiment, since the two electromagnetic coils in the two separated groups of driving components are electrically connected, when current is passed through the same group of electromagnetic coils connected in series, the directions of the magnetic fields generated by the two electromagnetic coils connected in series are opposite or the same, and by setting the magnetic pole directions of the two magnets corresponding to the two electromagnetic coils connected in series, the magnets corresponding to the two electromagnetic coils can be subjected to magnetic forces in different directions. In addition, the two electromagnetic coils connected in series can generate magnetic fields synchronously, so that the corresponding two magnets can be subjected to magnetic forces synchronously, which is beneficial to improve the control of the movement accuracy of the carrier.

[0016] In one possible implementation of the present application, the vibration assembly includes a vibration member and a carrier. The vibration member and the carrier are stacked and connected along the thickness direction of the substrate. The elastic part is arranged on the vibration member, and the carrier is arranged on the carrier.

[0017] In the above embodiment, since the vibration assembly is configured as a superimposed vibration member and a bearing member, the bearing member can be disposed on the bearing member, and the plurality of elastic members can be disposed on the vibration member, which facilitates processing and manufacturing of the bearing member and the plurality of elastic members.

[0018] In one possible implementation of the present application, a support member is provided with an avoidance through hole, and the support portion includes a plurality of clamping protrusions extending from the edge of the avoidance through hole toward the center of the support member, and in the radial direction of the optical lens, the side wall of the optical lens abuts against the clamping protrusions to fix the optical lens on the support member.

[0019] In the above embodiment, since the avoidance through hole is provided on the carrier, the light beam can be transmitted through the avoidance through hole. In addition, a plurality of clamping protrusions are provided on the edge of the avoidance through hole on the carrier, and the optical lens can be clamped and fixed on the carrier through the plurality of clamping protrusions, so that at least a part of the optical lens can be located in the avoidance through hole, which is beneficial to reduce the overall thickness of the diamond pixel expansion device equipped with the optical lens.

[0020] In one possible implementation of the present application, a support member is provided with an avoidance through hole, and along the thickness direction of the substrate, an edge of the avoidance through hole on the support member extends to form a fixing plate, and a portion of the driving component arranged on the vibration component is fixed on the fixing plate.

[0021] In the above embodiment, since a fixing sheet is provided on the carrier, the fixing sheet can provide a mounting point for the portion of the driving assembly mounted on the vibration assembly, so that a portion of the driving assembly can be mounted on the carrier. Furthermore, the fixing sheet is extended along the thickness direction of the substrate, which is conducive to reducing the space occupied by the fixing sheet and the driving assembly along the thickness direction of the substrate, thereby reducing the thickness of the diamond pixel expansion device.

[0022] In one possible implementation of the present application, a vibrating member is provided with a light through hole and four elastic parts. Within a vibration plane where the vibrating member is located, a first deflection axis and a second deflection axis divide the vibration plane into four vibration regions. Each elastic part is located within a vibration region, and the elastic part is located at an edge of the vibrating member away from the light through hole.

[0023] In the above embodiment, since the light through hole is provided on the vibrating member, the light beam can be transmitted through the light through hole. In addition, four elastic parts are provided on the vibrating member, and each elastic part is provided in a vibration area of ​​the vibrating member, so that the four elastic parts can be symmetrically distributed on the vibrating member, so that the four elastic parts can provide similar and evenly distributed supporting forces to the bearing member, thereby making the deflection movement of the bearing member relative to the deflection axis more stable.

[0041] The embodiment of the present application provides a diamond-shaped pixel expansion device, which can be used in a projection device, and can drive an optical lens to move through the diamond-shaped pixel expansion device to process the projection light of the projection device. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 1 shows an exploded schematic diagram of a diamond-shaped pixel expansion device provided by the present application, Figure 2 The structure diagram of the vibration component in the diamond pixel expansion device provided by the present application is shown. Figure 3 shows a schematic structural diagram of a carrier in a diamond-shaped pixel expansion device provided by the present application, Figure 4 The structure diagram of the vibration element in the diamond pixel expansion device provided by the present application is shown. Figure 5 A schematic structural diagram of a diamond pixel expansion device provided in the present application is shown.

[0042] The diamond pixel expansion device provided in the embodiment of the present application includes: a substrate 1, a vibration component 2 and a driving component 3; wherein the vibration component 2 has a bearing portion 21 and at least two elastic portions 22, the bearing portion 21 is used to mount the optical lens 7, and the vibration component 2 is mounted on the substrate 1 through a plurality of elastic portions 22, and each elastic portion 22 can generate elastic deformation; a plurality of groups of driving components 3 are respectively arranged at different positions between the substrate 1 and the vibration component 2; under the drive of the driving component 3, the vibration component 2 can deflect relative to the substrate 1 around the first deflection axis A1 and the second deflection axis A2 through a plurality of elastic portions 22, so as to drive the optical lens 7 to deflect relative to the substrate 1, and the first deflection axis A1 and the second deflection axis A2 satisfy a vertical relationship.

[0043] In the embodiment of the present application, the substrate 1 can be used to install and carry other parts in the diamond pixel expansion device, and the wires and electronic components in the circuit can also be set on the substrate 1.

[0044] For example, Figure 1 As shown, the substrate 1 can be set to a structural form including a support plate 11 and a circuit board 12. Among them, the support plate 11 can be made of a metal plate, a plastic plate, a rubber plate, etc., and the support plate 11 can be set to a flat plate structure. The circuit board 12 is used to set the wires and electronic components in the diamond pixel expansion device. The circuit board 12 and the support plate 11 can be bonded and fixed as a whole through an adhesive layer 13, and the adhesive layer 13 can be made of epoxy resin glue, polyurethane glue, etc.

[0045] As another example, the base 1 may be configured to include a circuit board 12. For example, the substrate in the circuit board 12 may be thickened to make the circuit board 12 have higher strength, so that other parts in the diamond pixel expansion device may be directly mounted on the circuit board 12.

[0046] In another example, a transmission through hole may be provided on the substrate 1. For example, the transmission through hole is provided on the substrate 1 near the center of the substrate 1, and the shape of the transmission through hole may be provided according to the shape of the optical lens 7 so that the projection light can be transmitted through the transmission through hole, thereby reducing the influence of the substrate 1 on the transmission of the projection light.

[0047] In the embodiment of the present application, the vibration component 2 can carry and install the optical lens 7, and can move relative to the base 1, so as to drive the optical lens 7 to move relative to the base 1.

[0048] For example, Figure 2 and Figure 3 As shown, a bearing portion 21 matching the shape and size of the optical lens 7 can be provided in the vibration component 2, so that the optical lens 7 can be fixed on the vibration component 2 through the bearing portion 21. Figure 2 and Figure 4 As shown, a plurality of elastic parts 22 may be provided on the vibration component 2. For example, two or four elastic parts 22 of equal number may be provided on the vibration component 2. Each elastic part 22 may be deformed. That is, when the elastic part 22 is subjected to an external force, the elastic part 22 may bend. When the external force disappears, the elastic part 22 may return to its original state.

[0049] In another example, a portion fixedly connected to the base 1 may be provided on the elastic portion 22, and each elastic portion 22 may be fixed on the base 1 to fix the vibration component 2 on the base 1. In this way, the vibration component 2 may move relative to the base 1 through the plurality of elastic portions 22.

[0050] In the embodiment of the present application, when the vibration component 2 moves relative to the base 1, it is necessary to apply a driving force to the bearing portion 21 of the vibration component 2. Then, a driving component 3 can be arranged between the vibration component 2 and the base 1 to apply a driving force to the bearing portion 21 through the driving component 3.

[0051] Exemplarily, along the circumferential direction of the vibration component 2, multiple groups of vibration components 2 can be sequentially distributed between the base 1 and the vibration component 2. In this way, driving force can be provided to the bearing portion 21 from multiple points, so that multiple driving forces can be applied to the bearing portion 21 according to a preset frequency and sequence by controlling multiple groups of driving components 3, so that the bearing portion 21 can produce a deflection motion relative to the base 1. For example, one group of driving components 3 located on the opposite sides of the vibration component 2 applies a pulling force to the bearing portion 21, and another group of driving components 3 applies a thrust to the bearing portion 21, then under the support of multiple elastic portions 22, the bearing portion 21 can be deflected relative to the base 1.

[0052] In the present application embodiment, Figure 5 As shown, by designing the positions and numbers of the multiple elastic parts 22 in the vibration component 2 and arranging the positions of the multiple groups of driving components 3 between the base 1 and the vibration component 2, the vibration component 2 can be made to deflect relative to the base 1 around the two deflection axes, and the first deflection axis A1 and the second deflection axis A2 can be made perpendicular. In this way, the optical lens 7 can be driven by the bearing part 21 to deflect relative to the base 1 around the first deflection axis A1 and the second deflection axis A2, so as to change the transmission path of the projection light transmitted through the optical lens 7.

[0053] The diamond pixel expansion device provided in the embodiment of the present application has a vibration component 2 installed on the substrate 1, and the vibration component 2 is connected to the substrate 1 through multiple elastic parts 22 on the vibration component 2, and the elastic parts 22 are set to a structural form that can produce elastic deformation, so that the vibration component 2 can move relative to the substrate 1; and a bearing part 21 is provided on the vibration component 2, and the optical lens 7 can be installed on the vibration component 2 through the bearing part 21. Multiple groups of driving components 3 are arranged between the substrate 1 and the vibration component 2, and the multiple groups of driving components 3 can provide forces to different positions of the vibration component 2 respectively, so that the vibration component 2 can drive the optical lens 7 to deflect relative to the substrate 1 around the deflection axis.

[0054] At the same time, the vibration component 2 is provided with a first deflection axis A1 and a second deflection axis A2, and the first deflection axis A1 and the second deflection axis A2 are arranged to satisfy a vertical relationship, so that the vibration component 2 can drive the optical lens 7 to reciprocate around the first deflection axis A1 and the second deflection axis A2 relative to the substrate 1. In this way, the first deflection axis A1 can be parallel to one symmetry axis of the diamond pixel, and the second deflection axis A2 can be parallel to another symmetry axis of the diamond pixel. In this way, in the process of the vibration component 2 driving the optical lens 7 to deflect around the first deflection axis A1 and the second deflection axis A2, after the light beam of the diamond pixel passes through the reciprocatingly deflected optical lens 7, the image of the diamond pixel can appear in four areas respectively within one cycle, and these four areas are located in the four areas above, below, left and right of the diamond pixel relative to the diamond pixel, so that a diamond image point similar to the diamond pixel but larger in area than the diamond pixel can be formed by the diamond image in the four areas. Therefore, the diamond pixel expansion device provided in the embodiment of the present application can realize the expansion of the diamond pixel, which is conducive to improving the quality of the projection picture.

[0055] In some possible embodiments of the present application, the diamond pixel expansion device includes four groups of drive components 3. In the circumferential direction along the vibration component 2, two groups of drive components 3 among the four groups of drive components 3 are relatively arranged on both sides of the vibration component 2 along the first deflection axis A1, and the other two groups of drive components 3 among the four groups of drive components 3 are relatively arranged on the other two sides of the vibration component 2 along the second deflection axis A2; or, the diamond pixel expansion device includes two groups of drive components 3. In the circumferential direction along the vibration component 2, one group of drive components 3 among the two groups of drive components 3 is arranged on one side of the vibration component 2 along the first deflection axis A1, and the other group of drive components 3 among the two groups of drive components 3 is arranged on the other side of the vibration component 2 along the second deflection axis A2.

[0056] In the present application embodiment, Figure 1 and Figure 2As shown, four groups of driving components 3 can be arranged in the diamond pixel expansion device to provide driving force to the bearing part 21 of the vibration component 2 from four points through the four groups of driving components 3.

[0057] For example, along the circumferential direction of the vibration component 2, a set of driving components 3 can be arranged on each side of the approximately rectangular vibration component 2. Figure 2 and Figure 5 As shown, along the first direction F, that is, along the extension direction of the first deflection axis A1, a set of drive components 3 can be respectively arranged on both sides of the vibration component 2, and the two sets of drive components 3 are respectively located on two opposite sides of the vibration component 2; along the second direction S, that is, along the extension direction of the second deflection axis A2, a set of drive components 3 can be respectively arranged on the other two sides of the vibration component 2, and the two sets of drive components 3 are respectively located on two opposite sides of the vibration component 2. Among them, the first direction F and the second direction S are two directions that are perpendicular or nearly perpendicular to each other in the plane where the vibration component 2 is located.

[0058] In this way, in the process of controlling the two groups of driving components 3 arranged along the first deflection axis A1 to apply driving forces in opposite directions to the bearing portion 21, the bearing portion 21 can generate a deflection movement relative to the base 1 around the second deflection axis A2 extending along the second direction S. In the process of controlling the two groups of driving components 3 arranged along the second deflection axis A2 to apply driving forces in opposite directions to the bearing portion 21, the bearing portion 21 can generate a deflection movement relative to the base 1 around the first deflection axis A1 extending along the first direction F.

[0059] In the embodiment of the present application, two groups of driving components 3 may also be provided in the diamond pixel expansion device, so as to provide driving force to the bearing portion 21 of the vibration component 2 from two points through the two groups of driving components 3 .

[0060] For example, along the circumferential direction of the vibration component 2, a set of driving components 3 can be respectively arranged on two adjacent sides of the approximately rectangular vibration component 2. Figure 2 and Figure 5 As shown, along the first direction F, a group of driving components 3 can be arranged on one side of the vibration component 2; along the second direction S, a group of driving components 3 can be arranged on the other side of the vibration component 2. In this way, along the circumferential direction of the vibration component 2, the two groups of driving components 3 are respectively located on two adjacent sides of the vibration component 2.

[0061] In this way, in the process of controlling the driving assembly 3 arranged along the first deflection axis A1 to apply a pulling force or a pushing force to the bearing portion 21 relative to the base 1, the bearing portion 21 can generate a deflection movement relative to the base 1 around the second deflection axis A2 extending along the second direction S. In the process of controlling the driving assembly 3 arranged along the second deflection axis A2 to apply a pulling force or a pushing force to the bearing portion 21 relative to the base 1, the bearing portion 21 can generate a deflection movement relative to the base 1 around the first deflection axis A1 extending along the first direction F.

[0062] In the above embodiment, since four groups of drive assemblies 3 are arranged between the vibration assembly 2 and the base 1, and the four groups of drive assemblies 3 are arranged in a distributed manner along the circumferential direction of the vibration assembly 2, the four groups of drive assemblies 3 can provide driving force to the bearing portion 21 of the vibration assembly 2 from four points; and two groups of drive assemblies 3 among the four groups of drive assemblies 3 are arranged along the first deflection axis A1, and the other two groups of drive assemblies 3 are arranged along the second deflection axis A2. Alternatively, two groups of drive assemblies 3 are arranged between the vibration assembly 2 and the base 1, and the two groups of drive assemblies 3 are arranged on two adjacent sides of the vibration assembly 2 in two directions perpendicular to each other. In this way, by controlling the drive assemblies 3 arranged perpendicularly to each other, the bearing portion 21 can generate a deflection motion relative to the base 1 around the first deflection axis A1 and the second deflection axis A2 perpendicular to each other.

[0063] In some possible embodiments of the present application, under the drive of the driving assembly 3 arranged along the first deflection axis A1, the first side 212 of the bearing portion 21 deflects around the second deflection axis A2 toward the direction close to the base 1, so that the bearing portion 21 is transformed from the balanced posture to the first deflection posture; or, under the drive of the driving assembly 3 arranged along the second deflection axis A2, the second side 213 of the bearing portion 21 deflects around the first deflection axis A1 toward the direction close to the base 1, so that the bearing portion 21 is transformed from the first deflection posture to the second deflection posture; or, under the drive of the driving assembly 3 arranged along the second deflection axis A1, the second side 213 of the bearing portion 21 deflects around the first deflection axis A1 toward the direction close to the base 1, so that the bearing portion 21 is transformed from the first deflection posture to the second deflection posture; Driven by the driving component 3, the first side 212 of the bearing part 21 deflects around the second deflection axis A2 in the direction away from the base 1, so that the bearing part 21 changes from the second deflection posture to the third deflection posture; or, driven by the driving component 3 arranged along the second deflection axis A2, the second side 213 of the bearing part 21 deflects around the second deflection axis A2 in the direction away from the base 1, so that the bearing part 21 changes from the third deflection posture to the fourth deflection posture; wherein, in the circumferential direction along the vibration component 2, the first side 212 and the second side 213 are two adjacent sides on the bearing part 21.

[0064] In an embodiment of the present application, a plurality of driving components 3 arranged in the diamond pixel expansion device can be installed with preset frequencies to input driving signals respectively, so that driving forces can be provided to different points of the bearing part 21 through the plurality of driving components 3 respectively, so as to change the posture of the bearing part 21.

[0065] For example, Figure 5 As shown, corresponding driving signals can be input to one or two driving components 3 arranged along the first deflection axis A1, so that the driving components 3 apply a pulling force to the first side 212 of the bearing part 21 along the first deflection axis A1 relative to the base 1, and / or apply a thrust to the side of the bearing part 21 opposite to the first side 212, and the first side 212 of the bearing part 21 will deflect around the second deflection axis A2 toward the direction close to the base 1. In this way, the bearing part 21 can be transformed from a state in a balanced posture relative to the base 1 to a first deflected posture.

[0066] In another example, corresponding driving signals may be input to one or two driving components 3 arranged along the second deflection axis A2, so that the driving components 3 apply a pulling force to the second side 213 of the bearing portion 21 along the second deflection axis A2 relative to the base 1, and / or apply a thrust to the side of the bearing portion 21 opposite to the second side 213, and the second side 213 of the bearing portion 21 will deflect around the first deflection axis A1 toward the direction close to the base 1. In this way, the bearing portion 21 can be transformed from a state in which it is in a first deflection posture relative to the base 1 to a second deflection posture.

[0067] In another example, corresponding driving signals may be input to one or two driving components 3 arranged along the first deflection axis A1, so that the driving components 3 apply a thrust to the first side 212 of the bearing portion 21 along the first deflection axis A1 relative to the base 1, and / or apply a pulling force to the side of the bearing portion 21 opposite to the first side 212, and the first side 212 of the bearing portion 21 will deflect around the second deflection axis A2 in a direction away from the base 1. In this way, the bearing portion 21 can be transformed from the state of being in the second deflection posture relative to the base 1 to the third deflection posture.

[0068] In another example, corresponding driving signals may be input to one or two driving components 3 arranged along the second deflection axis A2, so that the driving components 3 apply a thrust to the second side 213 of the bearing portion 21 along the second deflection axis A2 relative to the base 1, and / or apply a pulling force to the side of the bearing portion 21 opposite to the second side 213, and the second side 213 of the bearing portion 21 will deflect around the first deflection axis A1 in a direction away from the base 1. In this way, the bearing portion 21 can be transformed from the state of being in the third deflection posture relative to the base 1 to the fourth deflection posture.

[0069] In the embodiment of the present application, by controlling the multiple groups of driving components 3, the bearing portion 21 can be continuously cycled in the four postures of the first deflection posture, the second deflection posture, the third deflection posture and the fourth deflection posture. When the first deflection axis A1 and the second deflection axis A2 are respectively parallel to the symmetry axis of the diamond pixel, the projection light of the diamond pixel can be deflected by the optical lens 7 in one cycle and appear in the four regions of the upper, lower, left and right relative to the diamond pixel in sequence.

[0070] In the above embodiment, since the bearing part 21 of the vibration component 2 can be driven by multiple groups of driving components 3 to alternately deflect in four directions around the first deflection axis A1 and the second deflection axis A2 relative to the base 1, the projection light of the diamond pixel can be deflected four times within one cycle through the optical lens 7 installed on the bearing part 21, and then under the effect of the visual afterimage phenomenon, the diamond pixel can be amplified within one cycle.

[0071] In some possible embodiments of the present application, the driving component 3 includes corresponding permanent magnet components 31 and electromagnetic components 32, one of the permanent magnet components 31 and the electromagnetic components 32 is fixed on the base 1, and the other of the permanent magnet components 31 and the electromagnetic components 32 is fixed on the vibration component 2.

[0072] In the present application embodiment, Figure 1 and Figure 2 As shown, the driving component 3 in the diamond pixel expansion device can use a device that can generate a magnetic force to drive the carrier 24 through changes in magnetic attraction or magnetic repulsion.

[0073] Exemplarily, the driving component 3 can be configured to have a structure including a permanent magnet 31 and an electromagnetic component 32. The permanent magnet 31 can be a magnet, such as a neodymium iron boron magnet, a samarium cobalt magnet, a ferrite magnet, an alnico magnet, or other permanent magnets. The electromagnetic component 32 can be an electromagnetic coil, such as a coil made of conductive materials such as copper wire, aluminum wire, silver wire, and enameled wire. In this way, the permanent magnet 31 can be fixed on the substrate 1, and the electromagnetic coil can be fixed on the vibration component 2 at a position corresponding to the permanent magnet 31; or, the permanent magnet 31 can be fixed on the vibration component 2, and the electromagnetic coil can be fixed on the substrate 1 at a position corresponding to the permanent magnet 31.

[0074] As another example, the driving component 3 may also adopt a mechanism capable of realizing reciprocating motion, such as a cylinder, a hydraulic cylinder, a structure combining a motor and a cam, a crank slider structure, etc., thereby driving the bearing portion 21 of the vibration component 2 to produce reciprocating deflection motion relative to the base 1 around the deflection axis.

[0075] In the above embodiment, since the driving component 3 is configured to include a permanent magnet 31 and an electromagnetic component 32, the magnitude and direction of the current passed through the electromagnetic coil can be controlled to control the magnetic field strength of the magnetic field generated by the electromagnetic coil, thereby controlling the magnitude and direction of the magnetic force exerted on the permanent magnet 31. In addition, the magnitude, direction and frequency of the current passed through the electromagnetic coil are easy to control, thereby facilitating the control of the magnitude, direction and frequency of the magnetic force exerted on the permanent magnet 31.

[0076] In some possible embodiments of the present application, the electromagnetic component 32 includes an electromagnetic coil, and the permanent magnetic component 31 includes a magnet. In the circumferential direction of the vibration component 2, the two electromagnetic coils in the two groups of drive components 3 are electrically connected, and when the two electromagnetic coils are energized, the magnetic fields generated by the two electromagnetic coils are in opposite directions, which are the same as the directions of the magnetic poles of the two magnets corresponding to the two electromagnetic coils; or, in the circumferential direction of the vibration component 2, the two electromagnetic coils in the two groups of drive components 3 are electrically connected, and when the two electromagnetic coils are energized, the magnetic fields generated by the two electromagnetic coils are in the same direction, which are opposite to the directions of the magnetic poles of the two magnets corresponding to the two electromagnetic coils.

[0077] In the embodiment of the present application, when four groups of driving components 3 are provided in the diamond pixel expansion device, every two groups of electromagnetic components 32 in the four groups of driving components 3 can be connected into one group by electrical connection, so that the two groups of electromagnetic components 32 formed are controlled by two currents respectively.

[0078] For example, Figure 5 As shown, the electromagnetic coils in the two groups of drive components 3 arranged along the first deflection axis A1 can be connected in series through wires, and the electromagnetic coils in the other two groups of drive components 3 arranged along the second deflection axis A2 can also be connected in series through wires. That is, in the circumferential direction of the vibration component 2, two electromagnetic coils (another electromagnetic coil is distributed between the two electromagnetic coils) distributed at intervals among the four electromagnetic coils are connected in series through wires. And the rotation directions of the two electromagnetic coils connected in series are set to opposite rotation directions, that is, one electromagnetic coil of the two electromagnetic coils connected in series is wound clockwise, and the other electromagnetic coil is wound counterclockwise. When current is passed through the two electromagnetic coils connected in series, the magnetic fields generated by the two electromagnetic coils are in opposite directions. Correspondingly, in the direction of the magnet toward the electromagnetic coil, the two magnets corresponding to the two electromagnetic coils connected in series can be set to have the same magnetic pole direction. In this way, when current is passed through the two electromagnetic coils connected in series, the magnetic forces on the two magnets corresponding to the two electromagnetic coils are in opposite directions.

[0079] Another example, such as Figure 5As shown, the electromagnetic coils in the two groups of drive assemblies 3 arranged along the first deflection axis A1 can also be connected in series through wires, and the electromagnetic coils in the other two groups of drive assemblies 3 arranged along the second deflection axis A2 can also be connected in series through wires. And the rotation directions of the two electromagnetic coils connected in series are set to the same rotation direction, that is, when one of the two electromagnetic coils connected in series is wound clockwise, the other electromagnetic coil is also wound clockwise, and when one of the two electromagnetic coils connected in series is wound counterclockwise, the other electromagnetic coil is also wound counterclockwise. Then, when current is passed through the two electromagnetic coils connected in series, the magnetic fields generated by the two electromagnetic coils are in the same direction. Correspondingly, in the direction in which the magnets are facing the electromagnetic coils, the two magnets corresponding to the two electromagnetic coils connected in series can be set to have opposite magnetic pole directions. In this way, when current is passed through the two electromagnetic coils connected in series, the two magnets corresponding to the two electromagnetic coils are subjected to opposite magnetic forces.

[0080] In the above embodiment, since the two electromagnetic coils in the two separated groups of driving components 3 are electrically connected, when current is passed through the same group of electromagnetic coils connected in series, the directions of the magnetic fields generated by the two electromagnetic coils connected in series are opposite or the same, and by setting the magnetic pole directions of the two magnets corresponding to the two electromagnetic coils connected in series, the magnets corresponding to the two electromagnetic coils can be subjected to magnetic forces of different directions. In addition, the two electromagnetic coils connected in series can generate magnetic fields synchronously, so that the corresponding two magnets can be subjected to magnetic forces synchronously, which is beneficial to improve the control of the movement accuracy of the carrier 24.

[0081] In some possible embodiments of the present application, the vibration assembly 2 includes a vibration member 23 and a supporting member 24. In the thickness direction B along the substrate 1, the vibration member 23 and the supporting member 24 are stacked and connected, the elastic portion 22 is arranged on the vibration member 23, and the supporting portion 21 is arranged on the supporting member 24.

[0082] In the present application embodiment, Figure 1 and Figure 2 As shown, the vibration assembly 2 can be configured to have a structure including a vibration member 23 and a carrier 24 , so that the optical lens 7 is mounted via the carrier 24 , and the carrier 24 is moved relative to the base 1 via the vibration member 23 .

[0083] For example, Figure 3 As shown, the carrier 24 can be set to a substantially rectangular structure, the main body of the carrier 24 can be set to a plate-like structure, and the carrier portion 21 matching the optical lens 7 can be set on the main body of the carrier 24 to fix the optical lens 7 on the plate-like carrier 24. Figure 4As shown, the vibrating member 23 can be set as a thin plate-like approximately rectangular structure. For example, the vibrating member 23 can be made of a material with high strength and good toughness, such as stainless steel. A plurality of elastic parts 22 can be set on the thin plate-like vibrating member 23. In this way, along the thickness direction B of the substrate 1, the bearing member 24 and the vibrating member 23 can be stacked and arranged. For example, the bearing member 24 and the vibrating member 23 can be fixedly connected by bonding. Figure 1 and Figure 2 As shown, a second fastener 6, such as a screw, may also be used to fix the support member 24 and the vibration member 23 together.

[0084] As another example, the vibrating member 23 and the bearing member 24 may also be provided as an integrally formed structure, that is, the bearing portion 21 and the plurality of elastic portions 22 are provided on one part.

[0085] In the above embodiment, since the vibration component 2 is configured as a superimposed vibration member 23 and a supporting member 24, the supporting portion 21 can be disposed on the supporting member 24, and the plurality of elastic portions 22 can be disposed on the vibration member 23, so as to facilitate processing and manufacturing of the supporting portion 21 and the plurality of elastic portions 22.

[0086] In some possible embodiments of the present application, a support member 24 is provided with an avoidance through hole 241, and the support portion 21 includes a plurality of clamping protrusions 211 extending from the edge of the avoidance through hole 241 toward the center direction of the support member 24, and in the radial direction of the optical lens 7, the side wall of the optical lens 7 abuts against the clamping protrusions 211 to fix the optical lens 7 on the support member 24.

[0087] In the present application embodiment, Figure 3 As shown, a avoidance through hole 241 can be provided on the plate-shaped main body of the carrier 24 so that light can continue to be transmitted through the avoidance through hole 241. The carrier 21 can be provided on the edge of the avoidance through hole 241 on the carrier 24 so that the optical lens 7 can be fixed on the edge of the avoidance through hole 241.

[0088] Exemplarily, the avoidance through hole 241 can be set as a through hole that is approximately rectangular, and then clamping protrusions 211 can be set at the four corners of the avoidance through hole 241. In the plane where the main part of the carrier 24 is located, each clamping protrusion 211 extends from the edge of the avoidance through hole 241 to the center direction close to the carrier 24, that is, each clamping protrusion 211 extends to the center direction of the avoidance through hole 241. For example, two clamping protrusions 211 can be set at each corner of the avoidance through hole 241, and the two clamping protrusions 211 extend in two directions perpendicular to each other. Then, one corner of the rectangular optical lens 7 can be clamped between two mutually perpendicular clamping protrusions 211, so that the optical lens 7 can be clamped and fixed between the eight clamping protrusions 211.

[0089] In the above embodiment, since the avoidance through hole 241 is provided on the carrier 24, the light beam can be transmitted through the avoidance through hole 241. In addition, a plurality of clamping protrusions 211 are provided on the edge of the avoidance through hole 241 on the carrier 24, and the optical lens 7 can be clamped and fixed on the carrier 24 through the plurality of clamping protrusions 211, so that at least a part of the optical lens 7 can be located in the avoidance through hole 241, which is beneficial to reduce the overall thickness of the diamond pixel expansion device equipped with the optical lens 7.

[0090] In some possible embodiments of the present application, a support member 24 has an avoidance through hole 241 , and along the thickness direction B of the base 1 , an edge of the avoidance through hole 241 on the support member 24 extends to form a fixing plate 242 , and a portion of the driving component 3 disposed on the vibration component 2 is fixed on the fixing plate 242 .

[0091] In the embodiment of the present application, a structure for mounting the driving assembly 3 may be provided on the carrier 24 having the avoidance through hole 241 , so as to fix a part of the parts in the driving assembly 3 on the carrier 24 .

[0092] Exemplarily, a plurality of fixing pieces 242 may be formed by extending from the edge of the avoidance through hole 241 on the carrier 24, and each fixing piece 242 is formed by extending along the thickness direction B of the substrate 1. For example, a fixing piece 242 is formed by extending from each side of the approximately rectangular avoidance through hole 241, and each fixing piece 242 is located on the symmetry line of the avoidance through hole 241. For example, the permanent magnet 31 in the driving assembly 3 may be bonded and fixed to the fixing piece 242.

[0093] In the above embodiment, since the fixing sheet 242 is provided on the carrier 24, the fixing sheet 242 can provide a mounting point for the portion of the driving assembly 3 mounted on the vibration assembly 2, so that a portion of the driving assembly 3 can be mounted on the carrier 24. In addition, the fixing sheet 242 is extended along the thickness direction B of the substrate 1, which is conducive to reducing the space occupied by the fixing sheet 242 and the driving assembly 3 along the thickness direction B of the substrate 1, thereby reducing the thickness of the diamond pixel expansion device.

[0094] In some possible embodiments of the present application, the vibrating member 23 has a light through hole 232 and four elastic parts 22. In the vibration plane where the vibrating member 23 is located, the first deflection axis A1 and the second deflection axis A2 divide the vibration plane into four vibration areas. Each elastic part 22 is located in a vibration area, and the elastic part 22 is located on the edge of the vibrating member 23 away from the light through hole 232.

[0095] In the present application embodiment, Figure 4 As shown, the vibrator 23 can be set as a thin sheet structure with an approximate rectangular shape, and a light through hole 232 can be set on the vibrating body 231 of the vibrator 23, so that the light beam can be transmitted through the light through hole 232. An elastic part 22 can be set at each of the four corners of the vibrating body 231 with an approximate rectangular shape.

[0096] For example, within the vibration plane where the vibration member 23 is located, the first deflection axis A1 and the second deflection axis A2 can divide the vibration plane into four vibration regions, each of which includes a portion of a corner of the vibration member 23 that is approximately rectangular.

[0097] In another example, the elastic part 22 may be configured to include a connecting section 221 and a deforming section 222. The deforming section 222 is formed by extending from the edge of the vibration body 231 of the vibrating member 23. For example, the deforming section 222 may be configured to be a curved flat long strip structure. For example, if the deforming section 222 is configured to be approximately in the form of a "U", the deforming section 222 may be more easily elastically deformed when subjected to external force. A deforming section 222 may be provided on two adjacent sides of each corner of the vibration body 231, and the ends of the two deforming sections 222 away from the vibration body 231 are connected to the connecting section 221.

[0098] In another example, the connecting section 221 can be set as a thin sheet structure in a circular, square or other shape, and a through hole can be set on the connecting section 221. Correspondingly, a cushion block 4 can be set at a position corresponding to the connecting section 221 on the base 1. Then, a first fastener 5 matching the through hole can be used, such as a screw, which is passed through the through hole on the connecting section 221 and screwed into the cushion block 4, so as to fix the connecting section 221 to the base 1.

[0099] In the above embodiment, since the light through hole 232 is provided on the vibrating member 23, the light beam can be transmitted through the light through hole 232. In addition, four elastic parts 22 are provided on the vibrating member 23, and each elastic part 22 is provided in a vibration area of ​​the vibrating member 23, so that the four elastic parts 22 are symmetrically distributed on the vibrating member 23, so that the four elastic parts 22 can provide similar and evenly distributed supporting forces to the bearing member 24, thereby making the deflection movement of the bearing part 21 relative to the deflection axis more stable.

[0100] In addition, an embodiment of the present application also provides a projection device, which includes: an optical-mechanical assembly, a lens assembly, an optical lens 7 and a diamond pixel expansion device provided in any one of the above embodiments, wherein the optical lens 7 is mounted on the supporting portion 21, and the optical lens 7 is located between the optical-mechanical assembly and the lens assembly.

[0101] In the embodiment of the present application, the optical-mechanical assembly can generate projection light. The lens assembly is used to form the projection light into a projection picture of a desired size. The optical lens 7 can be an optical lens, such as a plane lens, and the optical lens 7 can be fixed on the bearing portion 21 of the vibration assembly 2 in the diamond pixel expansion device. And the diamond pixel expansion device can be arranged between the optical-mechanical assembly and the lens assembly, that is, the optical lens 7 is located on the transmission path of the projection light transmitted from the optical-mechanical assembly to the lens assembly. The diamond pixel expansion device drives the optical lens 7 carried by it to generate a high-frequency deflection motion relative to the deflection axis, and the projection light can be processed. The processed projection light passes through the lens assembly to form a projection picture projected onto the screen.

[0102] The projection device provided in the embodiment of the present application includes the diamond pixel expansion device provided in any of the above embodiments, and an optical lens 7 is installed on the bearing portion 21 of the vibration component 2 in the diamond pixel expansion device. Therefore, the expansion of the diamond pixels can be achieved, which is beneficial to improving the quality of the projected image.

[0103] The driving method of the diamond pixel expansion device provided in the embodiment of the present application is described below. Figure 6 and Figure 7 , Figure 6 shows a diamond pixel driving timing diagram provided by the present application, Figure 7 The schematic diagram of the movement path of the optical lens 7 of the diamond pixel provided by the present application is shown. When the diamond pixel expansion device is applied to a projection device using diamond pixels, the first deflection axis A1 and the second deflection axis A2 of the vibration component 2 need to be parallel to the symmetry axis of the diamond pixel respectively.

[0104] In a period T of a pixel display, the diamond pixel L expansion device can be controlled to generate four deflections to achieve four times of amplification of the diamond pixel L.

[0105] For example, Figure 6 As shown, in the first time sequence T1, that is, in the first quarter of a cycle T, a positive current Q1 can be input to the electromagnetic coils in the two groups of driving components 3 arranged along the first deflection axis A1, so that the electromagnetic coils close to the first side 212 of the bearing part 21 generate an attractive force on the magnet, and the electromagnetic coils away from the first side 212 of the bearing part 21 generate a repulsive force on the magnet; no current is input to the driving component 3 arranged along the second deflection axis A2. Then, the first side 212 of the bearing part 21 can be deflected around the second deflection axis A2 toward the direction close to the base 1. At this time, as shown in FIG. Figure 7 As shown, the optical lens 7 mounted on the carrier 21 is deflected upward relative to the rhombus pixel L, so that the projection light of the rhombus pixel L is shifted upward, that is, in the first time sequence T1, the image of the rhombus pixel L moves to Figure 7 At the position of W1 in the middle.

[0106] Another example, such as Figure 6 As shown, in the second time sequence T2, that is, in the second quarter of a cycle T, negative current Q2 can be input to the electromagnetic coils in the two groups of driving components 3 arranged along the second deflection axis A2, so that the electromagnetic coils close to the second side 213 of the bearing part 21 generate an attractive force on the magnet, and the electromagnetic coils away from the second side 213 of the bearing part 21 generate a repulsive force on the magnet; no current is input to the driving component 3 arranged along the first deflection axis A1. Then, the second side 213 of the bearing part 21 can be deflected around the first deflection axis A1 toward the direction close to the base 1. At this time, as shown in FIG. Figure 7 As shown, the optical lens 7 mounted on the carrier 21 is deflected to the right relative to the diamond pixel L, so that the projection light of the diamond pixel L is shifted to the right, that is, in the second time sequence T2, the image of the diamond pixel L moves to Figure 7 At the position of W2 in the middle.

[0107] Another example, Figure 6 As shown, in the third time sequence T3, that is, in the third quarter of a cycle T, negative current Q2 can be input to the electromagnetic coils in the two groups of driving components 3 arranged along the first deflection axis A1, so that the electromagnetic coils close to the first side 212 of the bearing part 21 produce a repulsive force on the magnet, and the electromagnetic coils away from the first side 212 of the bearing part 21 produce an attractive force on the magnet; no current is input to the driving component 3 arranged along the second deflection axis A2. Then, the first side 212 of the bearing part 21 can be deflected around the second deflection axis A2 in a direction away from the base 1. At this time, as shown in FIG. Figure 7As shown, the optical lens 7 mounted on the carrier 21 is deflected downward relative to the diamond pixel L, so that the projection light of the diamond pixel L is shifted downward, that is, in the third time sequence T3, the image of the diamond pixel L moves to Figure 7 At the position of W3 in the middle.

[0108] Another example, such as Figure 6 As shown, in the fourth time sequence T4, that is, in the last quarter of a cycle T, a positive current Q1 can be input to the electromagnetic coils in the two groups of driving components 3 arranged along the second deflection axis A2, so that the electromagnetic coils close to the second side 213 of the bearing part 21 produce a repulsive force on the magnet, and the electromagnetic coils away from the second side 213 of the bearing part 21 produce an attractive force on the magnet; no current is input to the driving component 3 arranged along the first deflection axis A1. Then, the second side 213 of the bearing part 21 can be deflected around the first deflection axis A1 in a direction away from the base 1. At this time, as shown in FIG. Figure 7 As shown, the optical lens 7 mounted on the carrier 21 is deflected to the left relative to the diamond pixel L, so that the projection light of the diamond pixel L is shifted to the left, that is, in the fourth time sequence T4, the image of the diamond pixel L moves to Figure 7 At the position of W4 in the middle.

[0109] In the embodiment of the present application, within the four driving timings of a period T, by respectively inputting corresponding driving currents to the four groups of driving components 3, that is, making the driving currents of the driving components 3 relatively arranged along the first deflection axis A1 and relatively arranged along the second deflection axis A2 differ by three quarters of a period, four shifts of the projection light of the diamond pixel L within one period T are achieved, and the four diamond images formed after the four shifts can be pieced together into a larger diamond image, thereby achieving four times amplification of the diamond pixel L within one period T.
