Description
Technical Field
The present invention relates to an optical assembly and a display device using the same, and more particularly, to an optical assembly for preventing a stopper from jumping off and a display device using the same.
Background
With the development of technology, display devices are widely used in many electronic products, such as mobile phones, tablet computers, watches, automobiles, and so on.
In a display device, especially a vehicle-mounted display device, a backlight module of the display device usually limits a light guide plate through a limiting block to prevent the light guide plate from vibrating and colliding with an iron shell to generate abnormal sound. The existing limiting block is generally fixed on an iron shell through an adhesive tape, and when the light guide plate vibrates upwards along the direction vertical to the plane of the light guide plate, the limiting block is easy to jump off due to the fact that the downward resistance of the limiting block is not enough to resist the force generated by vibration of the light guide plate. Similarly, when the light guide plate vibrates in a direction parallel to the plane of the light guide plate, the limiting block is also prone to jump off if the resistance of the limiting block in the opposite direction is not enough to resist the force generated by the vibration of the light guide plate. Once the limited block jumps, other film layers in the backlight module are wrinkled, so that poor pictures, such as ripples/white lines, are generated.
Therefore, how to provide an optical assembly capable of limiting the position of the limiting block in each direction and avoiding the limiting block from jumping off is one of the problems to be solved.

Detailed Description
The structural and operational principles of the present invention are described in detail below with reference to the accompanying drawings:
fig. 1 is a schematic view of an optical assembly structure according to an embodiment of the invention, and fig. 2 is a schematic view of the light guide plate shown in fig. 1 viewed along a direction a-a'. As shown in fig. 1 and fig. 2, the optical assembly 100 of the present invention includes a housing 101, a light guide plate 102, and a stopper 103. The light guide plate 102 and the stopper 103 are disposed in the casing 101, and the stopper 103 is disposed between the light guide plate 102 and the casing 101. The light guide plate 102 has a first side 1021 facing the stopper 103, and the stopper 103 has a second side 1031 facing the light guide plate 102. At least one position-limiting part 1022 is disposed on the first side 1021 of the light guide plate 102, and the position of the position-limiting part 1022 corresponds to the position of the position-limiting block 103. Fig. 1 of the present invention only shows one of the limiting blocks, and certainly, one or more limiting blocks may be disposed between each side edge of the light guide plate and the housing as required, and correspondingly, the position and the number of the limiting portions correspond to the limiting blocks, and one limiting portion may be disposed corresponding to one limiting block. FIG. 3 is a schematic view of the light guide plate of FIG. 1 viewed along the direction A-A'. As shown in fig. 3, in practical operation, a plurality of position-limiting portions 1022 may correspond to one position-limiting block 102, the position-limiting portions 1022 are disposed in parallel, for example, and the size of two adjacent position-limiting portions 1022 may be the same or different, which is not limited in the present invention.
Specifically, as shown in fig. 2, the position limiting part 1022 further includes a first position limiting part 10221, a second position limiting part 10222 and a third position limiting part 10223, the first position limiting part 10221 is arranged along the first direction D1, the second position limiting part 10222 is arranged along the second direction D2, and the third position limiting part 10223 is arranged along the third direction D3. At least two of the first direction D1, the second direction D2, and the third direction D3 are not parallel to each other.
In this embodiment, at least two directions of the first direction D1, the second direction D2, or the third direction D3 are not parallel to each other, so that the second position-limiting portion 10222 and the third position-limiting portion 10223 are inclined relative to the first position-limiting portion 10221 (the two directions may be symmetrical or asymmetrical relative to the first position-limiting portion 10221), the first position-limiting portion 10221, the second position-limiting portion 10222, and the third position-limiting portion 10223 form a groove-shaped structure, an opening of the groove-shaped structure faces a bottom surface of the light guide plate 102, that is, when the light guide plate 102 is located in the housing 101, the opening of the groove-shaped structure faces an upper surface of the housing 101, which carries the light guide plate 102. When the light guide plate 102 vibrates/moves along (or wants to vibrate) a certain direction, the first position-limiting portion 10221, the second position-limiting portion 10222 and the third position-limiting portion 10223 cooperate with each other to provide a balancing force to the position-limiting block 103 opposite to the vibration/movement direction of the light guide plate 102, so that the force on the position-limiting block 103 is balanced, and the position-limiting block 103 is prevented from jumping off.
As shown in fig. 1 and fig. 2, in the present embodiment, the second direction D2 is a horizontal direction; when the light guide plate 102 vibrates/moves along (or wants to vibrate/move along) the second direction D2 (rightward as viewed in the figure), a limiting force opposite to the second direction D2 is generated between the limiting part 1022 and the limiting block 103, for example, a friction force between the first limiting part 10221 and the limiting block 103, a horizontal friction component force opposite to the second direction D2 between the second limiting part 10222 or the third limiting part 10223 and the limiting block 103, and the like, so as to balance the stress of the limiting block 103 and prevent the limiting block 103 from jumping off. Similarly, when the light guide plate 102 vibrates/moves along (or wants to move along) the direction opposite to the second direction D2 (leftward in the figure), a limiting force in the second direction D2 is generated between the limiting portion 1022 and the limiting block 103 to balance the stress of the limiting block 103 and prevent the limiting block 103 from jumping off. When the light guide plate 102 vibrates/moves along (or wants to vibrate) the second direction D2 (upward in the figure), a limiting force perpendicular to the second direction D2 (downward in the figure) is generated between the limiting part 1022 and the limiting block 103, such as a friction force and/or a clamping resistance between the first limiting part 10221 and the limiting block 103, a downward friction component perpendicular to the second direction D2 between the second limiting part 10222 or the third limiting part 10223 and the limiting block 103, and the like, so as to balance the stress of the limiting block 103 and prevent the limiting block 103 from jumping off. Thus, the stopper 1022 can prevent the stopper 103 from jumping off in all directions.
The position-limiting portion shown in fig. 2 is a split structure, and is divided into three portions, namely a first position-limiting portion 10221, a second position-limiting portion 10222 and a third position-limiting portion 10223, where the first position-limiting portion 10221, the second position-limiting portion 10222 and the third position-limiting portion 10223 are continuous structures, but discontinuous between each two, and in actual operation, this is not a limitation. In order to simplify the process and facilitate the manufacturing process, the position-limiting portions may also be integrally formed (i.e., two or three of the first position-limiting portion 10221, the second position-limiting portion 10222 and the third position-limiting portion 10223 may be connected as shown in fig. 3), and disposed on the light guide plate.
As shown in fig. 2, a first included angle a1 is formed between the first direction D1 and the second direction D2, a second included angle a2 is formed between the second direction D2 and the third direction D3, and the first included angle a1 and the second included angle a2 may be symmetrically or asymmetrically arranged, that is, the angles of the first included angle a1 and the second included angle a2 may be the same or different. Specifically, a1 is more than or equal to 90 degrees and less than 180 degrees, a2 is more than or equal to 90 degrees and less than 180 degrees, more preferably, a1 is more than or equal to 120 degrees and less than or equal to 150 degrees, and a2 is more than or equal to 120 degrees and less than or equal to 150 degrees. When the first included angle a1 is 135 degrees and the second included angle a2 is 135 degrees, the limiting effect of the limiting part 1022 on the limiting block 103 is the best, and the limiting block 103 can be prevented from jumping off better.
FIG. 4 is a schematic view of the stop block shown in FIG. 1 viewed along the direction B-B'. As shown in fig. 1 to 4, the second side surface 1031 of the limiting block 103 is further provided with engaging portions 1032, and the arrangement positions and the number of the engaging portions 1032 are adapted to the arrangement positions and the number of the limiting portions 1022. In order to apply the restricting force more favorably, the stopper 1022 is provided as a first stopper convex portion, and the fitting portion 1032 is provided as a groove-shaped first fitting concave portion, the first stopper convex portion being provided in correspondence with the first fitting concave portion. When the optical assembly 100 is assembled, each of the first position-limiting protrusions is correspondingly embedded in the first embedding recess.
In an embodiment, the limiting block 103 is made of rubber or the like having elastic deformation capability, the first engaging recess may be a crack formed on the second side surface 1031 of the limiting block 103, the first limiting protrusion is a microstructure protrusion formed on the first side surface 1021 of the light guide plate 102, each microstructure protrusion is engaged with a corresponding crack by elastic deformation of each crack on the limiting block 103, and the limiting block 103 at the crack wraps the microstructure protrusion. When the light guide plate 102 is about to vibrate or displace, the friction force and/or the engagement resistance between the limiting block 103 and the limiting portion 1022 are increased by the cooperation of the microstructure protrusions and the cracks, and a balancing force opposite to the actuating direction of the light guide plate 102 is generated on the limiting block 103 to balance the stress of the limiting block 103, so that the limiting block 103 is kept stable.
Fig. 5 is a schematic cross-sectional view taken along line C-C' of fig. 2. As shown in fig. 5, the second position-limiting portion 10222 is a convex portion structure, which can be defined as a second convex portion 10222, and the cross section of the convex portion structure has a triangular shape or a rectangular shape. The first stopper 10221 and the third stopper 10223 may be respectively defined as a first convex portion 10221 and a third convex portion 10223, and the first convex portion 10221 and the third convex portion 10223 may have the same convex portion structure as the second stopper 10222, or may have different convex portion structures. Fig. 5 illustrates only a cross-sectional shape of the second position limiting portion 10222, which may be other shapes such as an ellipse and a polygon, and the present invention is not limited thereto.
As further shown in fig. 5, the second protrusion 10222 has a first end E1 close to the first side 1021 of the light guide plate 102 and a second end E2 opposite to the first end E1, the thickness of the first end E1 may be greater than that of the second end E2, and certainly, in order to better limit the escape of the stopper 103, the thickness of the second end E2 may be greater than that of the first end E1, so as to better fit with the matching portion.
Fig. 6 is a schematic structural diagram of an optical assembly according to another embodiment of the present invention. Different from fig. 2, the first position-limiting portion 10221, the second position-limiting portion 10222 and the third position-limiting portion 10223 are discrete structures, as shown in fig. 6, the first position-limiting portion 10221, the second position-limiting portion 10222 and the third position-limiting portion 10223 are all provided with convex structures, the convex structures are respectively formed by a plurality of convex points, and the cross section of each convex point is triangular or rectangular. Fig. 6 only shows that each of the position-limiting portions is composed of a specific number of bumps, and of course, the number of the bumps of the first position-limiting portion, the second position-limiting portion and the third position-limiting portion may be the same or different, and the cross-sectional shapes thereof may be the same or different, which is not limited in the present invention.
In order to better prevent the limiting block from jumping off, a damping structure can be further arranged on the surface of the shell contacted with the limiting block, the damping structure can be a bulge or a groove, and the arrangement position and the number of the damping structure correspond to the arrangement position and the number of the limiting block.

In an embodiment, when the limiting block 103 is made of rubber or the like having elastic deformation capability, the second engaging recess may be a crack formed on the third side 1033, and the second limiting protrusion is a microstructure protrusion formed on the fourth side 1011, and each microstructure protrusion may be embedded in each crack and wrapped by the limiting block 103 at each crack. When the light guide plate 102 is expected to vibrate or displace, the friction force and/or the clamping resistance between the microstructure protrusions and the cracks are increased through the matching of the microstructure protrusions and the cracks, and a balancing force opposite to the actuating direction of the light guide plate 102 is generated to assist in balancing the stress of the limiting block 103, so that the limiting block 103 is kept stable.
The invention also provides a display device which comprises a display panel and the optical assembly in the embodiment.
