Example one
The present invention provides a backlight module, and in an embodiment of the present invention, please refer to fig. 1 to fig. 6 in combination, the backlight module includes a back plate 100 and a rubber frame 200, the back plate 100 includes a bottom plate 110 and a side plate 120, the side plate 120 is connected to the bottom plate 110 and forms an accommodating cavity 101 with the bottom plate 110; the rubber frame 200 is arranged in the accommodating cavity 101 and is in inserted fit with the bottom plate 110; the side plate 120 is further provided with a stopping sheet 122, the stopping sheet 122 can be rotatably arranged on the side plate 120 and has a first position and a second position, when the stopping sheet 122 is located at the first position, the stopping is performed on one side, away from the bottom plate 110, of the fixed rubber frame 200, and when the stopping sheet 122 is located at the second position, the stopping sheet is used for avoiding the movement of the rubber frame 200 in the direction perpendicular to the bottom plate 110.
Specifically, referring to fig. 1 to 4, the backlight module includes a back plate 100, the back plate 100 is used for mounting a light source, a plastic frame 200 is mounted on the back plate 100 and used for forming a mounting space together with the back plate 100, so that the light source, a stacked diffusion plate, a stacked light guide plate and the like are mounted in the mounting space, and the plastic frame 200 is further used for supporting a display panel 400 in the display device. In the invention, the rubber frame 200 is in insertion fit with the bottom plate 110, so that when the rubber frame 200 is installed on the backboard 100, the rubber frame 200 can move along the direction vertical to the bottom plate 110 and the rubber frame 200 is inserted into the bottom plate 110, thereby preventing the backboard 100 from being scratched when the rubber frame 200 is obliquely assembled on the backboard 100. In addition, in this case, in order to ensure that the rubber frame 200 is not stopped by the stopping piece 122 when being inserted into the bottom plate 110 in the direction perpendicular to the bottom plate 110, in the assembling process, the stopping piece 122 may be rotated in advance to a position that does not affect the movement of the rubber frame 200 in the direction perpendicular to the bottom plate 110 (i.e., the stopping piece 122 is located at the second position), and after ensuring that the rubber frame 200 is completely inserted into the bottom plate 110, the stopping piece 122 is rotated to the first position so that the stopping piece 122 can stop the side of the rubber frame 200 departing from the bottom plate 110. The stop piece 122 may be disposed on the side plate 120 as a part of the side plate 120, so that the stop piece 122 may be bent to flexibly switch between the first position and the second position. Alternatively, the stopping piece 122 may be disposed separately from the side plate 120, and the stopping piece 122 is disposed on the side plate 120 in a hinged manner, so that the stopping piece 122 can rotate relative to the side plate 120 and rotate to the first position and the second position in the rotating process. It can be understood that, in the above two assembling processes, only the rubber frame 200 is installed on the backboard 100 along the direction perpendicular to the bottom board 110, and the stop piece 122 is rotated from the second position to the first position to stop the side of the rubber frame 200 departing from the bottom board 110, so that the assembling process is simple, the operation requirement is low, and the assembling automation is convenient to realize.
In order to achieve the effect of inserting and matching the rubber frame 200 with the bottom plate 110 and ensure that the rubber frame 200 can be installed on the bottom plate 110 of the backboard 100 along the direction perpendicular to the bottom plate 110, specifically, one of the rubber frame 200 and the bottom plate 110 may be opened with an insertion port, and the other may be provided with an insertion block, and the insertion block is inserted into the insertion port to achieve the effect of inserting and matching the rubber frame 200 with the bottom plate 110. For example, as shown in fig. 3 to 6, the bottom plate 110 is provided with an insertion port 111, and one side of the rubber frame 200 facing the bottom plate 110 is provided with an insertion block 210. Alternatively, in other embodiments, the bottom plate 110 is provided with a plug block, and one side of the rubber frame 200 facing the bottom plate 110 is provided with a plug port. It can be understood that, since the rubber frame 200 supports the display panel 400, for example, to ensure that the rubber frame 200 has better strength, the selectable bottom plate 110 is provided with the insertion port 111, the rubber frame 200 is convexly provided with the insertion block 210, and the insertion block 210 is inserted into the insertion port 111, so as to achieve the effect of insertion and matching of the rubber frame 200 and the bottom plate 110.
For convenience of explanation, the direction perpendicular to the bottom plate 110 is defined as the up-down direction, and it can be understood that, for example, when the insertion port 111 is formed on the bottom plate 110 and the insertion block 210 is disposed on the side of the rubber frame 200 facing the bottom plate 110, the opening direction of the insertion port 111 is only the up-down direction, so that after the insertion block 210 is inserted into the insertion port 111, the inner wall of the insertion port 111 can limit the left-right direction (one direction perpendicular to the up-down direction) and the front-back direction (the other direction perpendicular to the up-down direction and also perpendicular to the left-right direction) of the rubber frame 200. In addition, the stopping sheet 122 is disposed on the side plate 120 and used for stopping one side of the rubber frame 200 away from the bottom plate 110, so that the stopping sheet 122 and the bottom plate 110 can respectively limit the up-and-down direction of the rubber frame 200, and therefore, the assembling structure of the backboard 100 on the rubber frame 200 in the invention can well ensure the assembling stability of the rubber frame 200, and the rubber frame 200 can be prevented from scratching the backboard 100 in the assembling process.
Specifically, in the present invention, in order to achieve the effect that the stopping sheet 122 can stop the side of the rubber frame 200 departing from the bottom plate 110, at least a part of the stopping sheet 122 only needs to be disposed above the rubber frame 200, and further, the stopping sheet 122 can attach to the side of the rubber frame 200 departing from the bottom plate 110 or abut against the side of the rubber frame 200 departing from the bottom plate 110. It can be understood that the stopping sheet 122 has two surfaces with the largest area, and the two surfaces are oppositely arranged, wherein one surface with the largest area can be arranged on the side of the rubber frame 200 away from the bottom plate 110, i.e. the stopping sheet 122 arranged on the side plate 120 is arranged parallel to the side of the rubber frame 200 away from the bottom plate 110. Or, the surface with the largest area is arranged perpendicular to the side of the rubber frame 200 departing from the bottom plate 110, and at this time, one side edge of the stopping sheet 122 can abut against the side of the rubber frame 200 departing from the bottom plate 110, so that the side of the rubber frame 200 departing from the bottom plate 110 can still be stopped. In addition, the stopping sheet 122 is arranged on the side plate 120, which means that the stopping sheet 122 and the side plate 120 are in an integral structure, and a part of the side plate 120 is bent to form the stopping sheet 122; alternatively, the stop piece 122 may be hinged to the side plate 120. The stop piece 122 can be provided with a plurality of at intervals to have better backstop effect to gluing frame 200, and glue frame 200 to the power of holding of backstop piece 122 can disperse to each stop piece 122 on, thereby make the power that each stop piece 122 received less, avoid the stop piece 122 to appear seriously warping and influence life.
According to the technical scheme of the invention, the rubber frame 200 is in inserted fit with the bottom plate 110, so that the rubber frame 200 can move along the direction vertical to the bottom plate 110 and be inserted together when being installed on the backboard 100, thereby realizing the connection effect of the rubber frame 200 and the backboard 100, and avoiding the situation that the backboard 100 is scratched by the rubber frame 200 in the assembling process. In addition, by arranging the rotatable stopping piece 122 on the side plate 120, the stopping piece 122 stops the side of the rubber frame 200 departing from the bottom plate 110 when in the first position, so that the installation effect of the rubber frame 200 is further improved, and the insertion block 210 of the rubber frame 200 is prevented from being separated from the insertion port 111. Meanwhile, the stop piece 122 also has a second position, in which it can avoid the movement of the rubber frame 200 in the direction perpendicular to the bottom plate 110, and further simplifies the assembly step of the rubber frame 200 to the backboard 100.
Further, referring to fig. 1 and fig. 2, a cut 121 is formed on a side of the side plate 120 away from the bottom plate 110, and the stop piece 122 is rotatably connected to an inner wall of the cut 121.
Through the cut-out 121 is opened on the side of the side plate 120 far away from the bottom plate 110, and the stopping piece 122 is rotatably connected to the inner wall of the cut-out 121, in the rotating process of the stopping piece 122, the stopping piece 122 can have a state of stopping the side of the rubber frame 200 far away from the bottom plate 110. In addition, the side of the side plate 120, which is far away from the bottom plate 110, is provided with the notch 121, so that the notch 121 provides an avoidance space, so that the stopper piece 122 can rotate into the notch 121 in the rotating process, and the effect of avoiding the movement of the rubber frame 200 along the direction perpendicular to the bottom plate 110 is further achieved.
Further, as shown in fig. 4, the stopping sheet 122 and the side plate 120 are of an integral structure, and a fold is formed at a connection position of the stopping sheet 122 and the side plate 120, so that the stopping sheet 122 can be bent to the first position relative to the fold or can be folded back to the second position relative to the fold.
By integrating the stopping sheet 122 with the side plate 120, the stopping sheet 122 and the side plate 120 are combined into a whole, so that the connecting strength between the stopping sheet 122 and the side plate 120 is improved. In addition, since the folding lines are formed on the whole, the folding lines are formed at the joints of the stop pieces 122 and the side plates 120, so that on one hand, the stop pieces 122 can be bent along the folding lines relative to the side plates 120 to reach the first position, and thus, the side of the rubber frame 200 departing from the bottom plate 110 is limited and stopped; on the other hand, the stopping sheet 122 is folded back to the second position from the first position along the fold line relative to the side plate 120 so as to avoid the movement of the glue frame 200 along the direction vertical to the bottom plate 110. It will be appreciated that after the stop tab 122 is folded back along the fold to the second position, the stop tab 122 is located within the cutout 121.
Further, as shown in fig. 4, the stop piece 122 is disposed perpendicular to the bottom plate 110 when in the first position.
Through when first position, the perpendicular bottom plate 110 setting of stopping piece 122, then when gluing frame 200 and having the support that deviates from the bottom plate 110 direction to stopping piece 122 and hold the power, stopping piece 122 is difficult to take place to deform or be difficult to relative curb plate 120 and rotate, and it can keep comparatively stable state to further reverse have more firm spacing effect to gluing frame 200.
Further, referring to fig. 2 and fig. 6 in combination, a groove 220 is formed in a side of the rubber frame 200 away from the bottom plate 110, the groove 220 includes a bottom wall 221 and a side wall 222, the bottom wall 221 and the side wall 222 are connected and jointly enclose to form a first notch 220a, the bottom wall 221 of the groove 220 is opposite to the first notch 220a, and the stop piece 122 abuts against the bottom wall of the groove 220.
Through being equipped with recess 220 in the side that glues frame 200 and deviate from bottom plate 110, backstop piece 122 supports the diapire that holds recess 220, then can guarantee that backstop piece 122 can play better spacing backstop effect to gluing frame 200. In addition, by such arrangement, the stopping sheet 122 is supported in the groove 220, so that the stopping sheet 122 is prevented from excessively protruding out of one side of the rubber frame 200 departing from the bottom plate 110, and the flatness of the backboard 100 and the rubber frame 200 after installation is maintained as much as possible.
Further, with continued reference to fig. 2 and fig. 6, the side wall 222 and the bottom wall 221 further enclose a second notch 220b, and the second notch 220b is open toward the notch 121 and is communicated with the notch 121; when the stopping sheet 122 is located at the first position, it passes through the second slot 220b and also abuts against the sidewall 222.
When the stopping sheet 122 abuts against the bottom wall of the groove 220, the side wall of the groove 220 can be limited at the same time, so that the rubber frame 200 is further limited in the direction perpendicular to the side wall of the groove 220. Meanwhile, the side wall of the groove 220 can limit the stop piece 122, so that the stop piece 122 is prevented from rotating relative to the side plate 120 by an excessively large angle and being parallel to the side plate 120, and the stop rubber frame 200 cannot play a role in deviating from one side of the bottom plate 110.
Further, referring to fig. 4 and fig. 6, a projection of the bottom wall 221 of the groove 220 on the bottom plate 110 is at least partially overlapped with a projection of the insertion block 210 on the bottom plate 110.
