Description

Technical Field

[0001] The present invention relates to the field of product assembly technology with anti-shake requirements, and in particular to a shake adjustment module and an assembly technology. Background Art

[0002] Projection technology has been widely adopted in both commercial and residential settings. To improve the resolution of images projected onto screens, a common approach is to add a polarizing filter. This back-and-forth oscillation of the polarizing filter increases the projected image resolution, thereby enhancing the user experience.

[0003] The existing technology uses screws and springs to install the polarizing filter on the projector. The shaking of the spring drives the polarizing filter to vibrate, thereby adjusting the resolution of the projected image. However, when using screws to fix the spring, the flatness of the spring is required to be high. If the spring used is deformed, forced assembly will result in poor product actuation consistency, and the center position accuracy of the central glass diffuser after assembly is low.

[0009] As for the jitter adjustment module described above, the first special-shaped glue dispensing groove, the second special-shaped glue dispensing groove, the third special-shaped glue dispensing groove and / or the fourth special-shaped glue dispensing groove have the same shape.

[0010] As described above, in the jitter adjustment module, one or more of the first special-shaped glue dispensing groove, the second special-shaped glue dispensing groove, the third special-shaped glue dispensing groove and the fourth special-shaped glue dispensing groove are limiting special-shaped grooves, and the limiting special-shaped grooves include a front protrusion and a rear protrusion. The distance W between the front protrusion and the rear protrusion is smaller than the length or width L of the notch of the first free glue dispensing groove, the second free glue dispensing groove, the third free glue dispensing groove or the fourth free glue dispensing groove. The front protrusion and the rear protrusion are used to fix the first spring piece, the second spring piece, the fourth spring piece or one end of the fourth spring piece.

[0011] As described above, the jitter adjustment module is further provided with a stabilizing protrusion in the special-shaped groove, and the stabilizing protrusion is used to divide the special-shaped groove into a partially connected groove A and a groove B.

[0012] As for the jitter adjustment module described above, the movable inner frame, the movable outer frame and the fixing seat are all provided with an auxiliary through-hole group for assisting in fixing the relative positions of the movable inner frame, the movable outer frame and the fixing seat.

After the glue solidifies, the elastic force of the first spring piece, the second spring piece, the third spring piece and the fourth spring piece are the same, and the consistency of each spring piece is good, which can ensure that the position of the center lens remains basically unchanged after the jitter adjustment.

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interactively without conflicting with each other.

[0019] Reference Figure 1 A jitter adjustment module includes a movable inner frame 1 with a central lens 11, the movable inner frame 1 being connected to a movable outer frame 4 via a first elastic piece 2 and a second elastic piece 3 so that the movable inner frame 1 is mounted in the movable outer frame 4, and the movable outer frame 4 being connected to a fixing seat 7 via a third elastic piece 5 and a fourth elastic piece 6 so that the movable outer frame 4 is mounted in the fixing seat 7; The first elastic piece 2 and the second elastic piece 3 are both fixed to the movable inner frame 1 and the movable outer frame 4 by glue dispensing; The third elastic piece 5 and the fourth elastic piece 6 are both fixed to the movable outer frame 4 and the fixing seat 7 by glue dispensing.

[0020] In this embodiment, the two ends of the first spring piece 2 and the second spring piece 3 are fixed to the movable inner frame 1 and the movable outer frame 4 respectively, and the two ends of the third spring piece 5 and the fourth spring piece 6 are fixed to the movable outer frame 4 and the fixing seat 7 respectively. Compared with using screws to fix the spring pieces (including the first spring piece 2, the second spring piece 3, the third spring piece 5 and the fourth spring piece 6), the glue fixation can make the spring pieces in a naturally stretched state, which can reduce the probability of deformation of the spring pieces after assembly is completed. Before the glue solidifies, the positions of the movable inner frame 1, the movable outer frame 2 and the fixed base 7 are fixed. After the glue solidifies, the elastic forces of the first spring piece 2, the second spring piece 3, the third spring piece 5 and the fourth spring piece 6 are the same, which can ensure that the position of the center lens 11 remains basically unchanged after the jitter adjustment.

[0021] The screw fixation used in the prior art has very high requirements for flatness. Since the spring piece is fixed in its natural state in this embodiment, the requirements for the flatness of the spring piece are lower than those in the prior art, which does not affect its elastic force and has little effect on the consistency of product movement.

[0022] Specifically, the first spring piece 2 , the second spring piece 3 , the third spring piece 5 and the fourth spring piece 6 have the same elastic force and are all made of the same material.

[0023] More specifically, the first spring piece 2 , the second spring piece 3 , the third spring piece 5 and the fourth spring piece 6 are all metal spring pieces.

[0024] Reference Figure 1 In one embodiment, the first spring clip 2, the second spring clip 3, the third spring clip 5, and the fourth spring clip 6 respectively form the four sides of a quadrilateral, and the central lens 11 is located at the center of the quadrilateral. During vibration, the movable inner frame 1 is subjected to uniform and equal tension from the first and second spring clips 2 and 3, resulting in balanced forces. During use, the jitter adjustment module is positioned adjacent to the projection module of a projector, with the central lens 11 positioned adjacent to the projection module. This embodiment ensures that light emitted from the projection module always passes through the central lens 11, ensuring the effectiveness of the jitter adjustment module.

[0025] Specifically, the central lens 11 is rectangular, and the intersection of the diagonals of the central lens 11 overlaps with the intersection of the diagonals of the quadrilateral formed by the first elastic piece 2 , the second elastic piece 3 , the third elastic piece 5 and the fourth elastic piece 6 .

[0026] Specifically, the first elastic piece 2 and the second elastic piece 3 are parallel, and the third elastic piece 5 and the fourth elastic piece 6 are parallel.

[0027] Reference Figure 3 In one embodiment, the first spring piece 2, the second spring piece 3, the third spring piece 5 and the fourth spring piece 6 have the same shape, and a fixed through groove 356 is provided at any one end or both ends. The fixed through groove 356 allows unsolidified glue to pass through and solidify therein, thereby increasing the stability of the assembly of the first spring piece 2, the second spring piece 3, the third spring piece 5 and the fourth spring piece 6.

[0028] Reference Figure 1 In one embodiment, the fixing seat 7 is provided with a first special-shaped glue dispensing groove 71 and a second special-shaped glue dispensing groove 72 at the diagonal portions thereof, and the movable outer frame 4 is provided with a first free glue dispensing groove 41 and a second free glue dispensing groove 42 at the diagonal portions thereof. The movable outer frame 4 is provided with a third special-shaped glue dispensing groove 43 and a fourth special-shaped glue dispensing groove 44 at the inner diagonal portions thereof, and the movable inner frame 1 is provided with a third free glue dispensing groove 13 and a fourth free glue dispensing groove 14 at the inner diagonal portions thereof; The two ends of the first spring piece 2 are respectively fixed in the third special-shaped glue dispensing groove 43 and the third free glue dispensing groove 13, the two ends of the second spring piece 3 are respectively fixed in the fourth free glue dispensing groove 14 and the fourth special-shaped glue dispensing groove 44, the two ends of the third spring piece 5 are respectively fixed in the first special-shaped glue dispensing groove 71 and the first free glue dispensing groove 41, and the two ends of the fourth spring piece 6 are respectively fixed in the second special-shaped glue dispensing groove 72 and the second free glue dispensing groove 42.

[0029] Among them, the first special-shaped glue groove 71, the second special-shaped glue groove 72, the third special-shaped glue groove 43 and the fourth special-shaped glue groove 44 have the same function, which is to constrain one end of the spring. Before the glue solidifies, one end of the spring is constrained, and the other end is located in the first free glue groove 41 / the second free glue groove 42 / the third free glue groove 13 or the fourth free glue groove 14 in a stretched state. When the glue is fixed, even if the spring has a slight deformation and a slight change in flatness, it will not affect the elasticity of the spring, further reducing the requirements for the flatness of the spring, and further reducing the impact of the deformed spring on the consistency of the product.

[0030] It can be understood that the shapes of the first special-shaped glue dispensing groove 71, the second special-shaped glue dispensing groove 72, the third special-shaped glue dispensing groove 43 and the fourth special-shaped glue dispensing groove 44 in this embodiment are more complex than the shapes of the first free glue dispensing groove 41, the second free glue dispensing groove 42, the third free glue dispensing groove 13 and the fourth free glue dispensing groove 14.

[0031] It can be seen from the above scheme that the first spring piece 2 and the second spring piece 3 will pull the movable inner frame 1 and the movable outer frame 4 when vibrating, and the third spring piece 5 and the fourth spring piece 6 will pull the movable outer frame 4 and the fixed seat 7 when vibrating. In order to reduce the damage caused by stress concentration to the movable inner frame 1, the movable outer frame 4 and the fixed seat 7, the first special-shaped glue groove 71 and the second special-shaped glue groove 72, the third special-shaped glue groove 43 and the fourth special-shaped glue groove 44 are respectively arranged at the diagonals to balance the pulling force of each spring piece on the movable inner frame 1, the movable outer frame 4 and the fixed seat 7, thereby reducing the risk of damage caused by excessive stress on one side and extending the service life of the movable inner frame 1, the movable outer frame 4 and the fixed seat 7.

[0032] Reference Figure 1 In one embodiment, the first special-shaped glue dispensing groove 71, the second special-shaped glue dispensing groove 72, the third special-shaped glue dispensing groove 43 and / or the fourth special-shaped glue dispensing groove 44 have the same shape and can be made into the above-mentioned special-shaped grooves using the same groove mold or process, thereby reducing the manufacturing cost of the jitter adjustment module.

[0033] Reference Figure 4 In one embodiment, one or more of the first special-shaped glue dispensing groove 71, the second special-shaped glue dispensing groove 72, the third special-shaped glue dispensing groove 43 and the fourth special-shaped glue dispensing groove 44 are limited special-shaped grooves, and the limited special-shaped grooves include a front protrusion 81 and a rear protrusion 82. Along the length direction of the spring piece, the distance W between the front protrusion 81 and the rear protrusion 82 is smaller than the length or width of the first free glue dispensing groove 41, the second free glue dispensing groove 42, the third free glue dispensing groove 13 or the fourth free glue dispensing groove 14. The front protrusion 81 and the rear protrusion 82 are used to fix the first spring piece 2, the second spring piece 3, the fourth spring piece 6 or one end of the fourth spring piece 6.

[0034] Taking the third spring piece 5 as an example, before glue is dispensed, the two ends of the third spring piece 5 are respectively placed in the first special-shaped glue dispensing groove 71 and the first free glue dispensing groove 41. The front protrusion 81 and the rear protrusion 82 of the first special-shaped glue dispensing groove 71 restrict the movement of one end of the third spring piece 5. The third spring piece 5 is fixed with the first special-shaped glue dispensing groove 71 as a reference. The other end of the third spring piece 5 is in a natural unconstrained state. After the glue in the first special-shaped glue dispensing groove 71 and the first free glue dispensing groove 41 solidifies, the third spring piece 5 is fixed. This further reduces the influence of the deformed third spring piece 5 on the product consistency and the position accuracy of the center lens 11 after assembly is completed, and does not increase the difficulty of operation. Furthermore, the arrangement of the front protrusion 81 and the rear protrusion 82 increases the complexity of the special-shaped groove structure. The dripped glue can fill the corners and turning points of the special-shaped groove. The glue solidified in the special-shaped groove is less likely to fall off and has stronger adhesion, reducing the possibility of the spring piece falling off from the special-shaped groove.

[0035] Reference Figure 4 In one embodiment, a stabilizing protrusion 83 is further provided in the irregular groove to divide the irregular groove into a partially connected groove A 84 and a groove B 85. The stabilizing protrusion 83 further increases the complexity of the irregular groove. When glue is dripped into the irregular groove, the glue flows within the irregular groove, filling groove A 84 and groove B 85, further preventing the solidified glue from escaping from the irregular groove.

[0036] Specifically, taking the third spring piece 5 as an example, the third spring piece 5 is placed in the A groove 84 and the B groove 85, and the fixed groove 356 is adjacent to the stabilizing protrusion 83. The glue at the fixed groove 356 is connected to the glue in the A groove 84 and the B groove 85, further reducing the probability of the third spring piece 5 detaching from the special-shaped groove.

[0037] Reference Figure 1 In one embodiment, the movable inner frame 1, the movable outer frame 4, and the fixing base 7 are each provided with a set of auxiliary through-holes to assist in securing the relative positions of the movable inner frame 1, the movable outer frame 4, and the fixing base 7. Before applying the glue and installing the springs, any pins or fixing posts that can pass through the set of auxiliary through-holes can be used to secure the relative positions of the movable inner frame 1, the movable outer frame 4, and the fixing base 7, thereby improving the installation accuracy of the center lens 11 after assembly.

[0038] Reference Figure 1 and Figure 2 In one embodiment, the auxiliary through-hole group includes at least two inner frame through-holes 91 provided on the movable inner frame 1, at least two outer frame through-holes 92 provided on the movable outer frame 4, and the fixing seat 7 is provided with at least two first base through-holes 93 corresponding one-to-one to the inner frame through-holes 91, and at least two second base through-holes 94 corresponding one-to-one to the outer frame through-holes 92.

[0039] There are at least two inner frame through holes 91, outer frame through holes 92, first base through holes 93 and second base through holes 94. The two fixed points can form a stable reference to fix the relative positions of the movable inner frame 1, the movable outer frame 4 and the fixing seat 7, and fix the position of the center lens 11.

[0040] As an example, during assembly, the movable inner frame 1 is installed in the movable outer frame 4, the movable outer frame 4 is installed in the fixed seat 7, the pins are inserted into the corresponding inner frame through holes 91 and the first base through holes 93, and the second base through holes 94 are inserted into the corresponding movable outer frame 4, so as to fix the relative positions of the movable inner frame 1, the movable outer frame 4 and the fixed seat 7, install the first spring clip 2, the second spring clip 3, the third spring clip 5 and the fourth spring clip 6, apply glue, remove the pins, and complete the assembly.

[0041] This embodiment also provides a jitter adjustment module assembly process, including the following steps: Install the movable inner frame 1 with the central lens 11 into the movable outer frame 4; Install the movable outer frame 4 in the fixing seat 7; Place the first spring piece 2 and the second spring piece 3 on the movable inner frame 1 and the movable outer frame 4; Place the third spring piece 5 and the fourth spring piece 6 on the movable outer frame 4 and the fixing seat 7; Glue is applied to the movable inner frame 1, the movable outer frame 4, and the fixing seat 7 to secure the ends of the first spring 2, the second spring 3, the third spring 5, and the fourth spring. The above-mentioned vibration adjustment module can be manufactured using this process. The springs of the manufactured vibration adjustment module have good consistency, ensuring that the position of the center lens 11 remains substantially unchanged after vibration adjustment.

[0042] The above is a specific description of the preferred implementation of the present invention, but the invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
