The backlight module 20 of the present embodiment generally includes a mounting substrate 21, the mounting substrate 21 is cooperatively connected with the frame body 10 through the above structure, when the mounting substrate 21 is mounted on the frame body 10, the mounting substrate 21 presses the first sealing rubber 113 against the first sealing groove 112, and a light source and an optical film, which are used for providing illumination light for the display module, are disposed on the mounting substrate 21, and are disposed at the rear side of the mounting substrate 21, so as to control components such as a circuit board structure of an interactive flat panel.

The first accommodating portion 11 is provided with a first sealing groove 112 on the first mounting surface 111, and the first sealing groove 112 extends along the length direction of the first mounting surface 111, so that the first sealing groove 112 is disposed on the first mounting surface 111 along the length direction of the frame body 10. The first sealing rubber strip 113 is embedded in the first sealing groove 112, the first sealing rubber strip 113 may be a solid silica gel, which has a certain elasticity and an elastic resetting capability, and the solid silica gel has characteristics of good elasticity, high and low temperature resistance, slight acid and alkali resistance, and difficult aging and deformation, the first sealing rubber strip 113 is used to be in sealing contact with the backlight module 20, specifically the mounting substrate 21 and the first sealing groove 112, in the assembled state of the backlight module 20 and the frame body 10, so as to prevent the medium (rain, air, sand and dust, etc.) outside the interactive flat plate from intruding, and due to the good elasticity, the first sealing rubber strip can prevent damage caused by mechanical shock and impact to a certain extent, maintain good water tightness between the backlight module 20 and the frame body 10 to a certain extent, and also can play a certain protection role on the backlight module 20, thereby achieving sealing, Shock absorption and the like.

Moreover, because the solid silica gel has the characteristic of slight acid and alkali resistance, in the long-term use process of the interactive flat plate, even if the interactive flat plate is contacted with moisture containing certain pH value in the cleaning process or the daily use process, the first sealing rubber strip 113 can not be aged due to rapid chemical reaction, so that the reliability of the interactive flat plate is improved, and the service life of the equipment is prolonged.

After the first sealing rubber strip 113 in the present embodiment is disposed in the first sealing groove 112, in general, at least a portion of the first sealing rubber strip 113 protrudes out of the first sealing groove 112, and a portion of the first sealing rubber strip 113 protruding out of the first sealing groove 112 is higher than the first mounting surface 111; certainly, a side of the first sealing rubber strip 113 may also be set in a state of not protruding out of the first sealing groove 112, and the front side of the backlight module 20, that is, the side facing the first mounting surface 111, is set in a propping structure opposite to the first sealing groove 112, so that when the backlight module 20 is mounted on the frame body 10, the first sealing rubber strip 113 is collided by the propping structure to achieve the same technical effect.

In the embodiment, a structural scheme that the first sealing rubber strip 113 is assembled in the first sealing groove 112 and protrudes from the first mounting surface 111 is adopted, and when the backlight module 20 is assembled on the frame body 10, the first sealing rubber strip 113 respectively abuts against the backlight module 20 and the first sealing groove 112, and forms a sealed state with the backlight module 20 and the first sealing groove 112.

Compared with the traditional scheme of injecting glue between a back plate and a frame, the scheme of the backlight module 20 and the first sealing rubber strip 113 in the embodiment, and the frame body 10 and the first sealing rubber strip 113 both realize the waterproof sealing function through the mutual interference mode, generally speaking, in the length direction of the frame body 10, one side of the backlight module 20 connected with the frame body 10 is kept with the first sealing groove 112 to form a planar structure, therefore, the backlight module 20, the first sealing groove 112 and the first sealing rubber strip 113 are kept in the interference relationship in the length direction of the frame body 10, and therefore the water sealing structure between the backlight module 20 and the frame body 10 has higher reliability. And, because the backlight module 20 and the frame body 10 realize the watertight fit through the first joint strip 113, the watertight sealing structure between the two is the structure of non-fixed connection, therefore, detachable connection can be realized between the backlight module 20 and the frame body 10, when the backlight module 20 of the display is damaged and failed, the mounting substrate 21 and the interactive flat plate of the backlight module 20 can realize the separation between the backlight module 20 and the frame body 10 only by detaching the connection structure between the two, the mounting substrate 21 can not be damaged by adhesion due to the existence of liquid silica gel in the detaching process, the detaching difficulty of the backlight module 20 is reduced, and further, the maintenance and replacement of the backlight module 20 are facilitated. Since the first sealing rubber strip 113 is in a non-fixed connection assembly relationship with the first sealing groove 112, the first sealing rubber strip 113 can be replaced by disassembling the backlight module 20 and the frame body 10 after aging, so as to keep the water tightness between the two meeting the requirements of the whole equipment.

In an embodiment, in the width direction of the frame body 10, a deformation gap 114 is formed between the first sealing rubber strip 113 and the first sealing groove 112, and the deformation gap 114 may be formed by different cross-sectional shapes between the first sealing rubber strip 113 and the first sealing groove 112, for example, the cross-section of the first sealing rubber strip 113 is substantially circular, and the cross-sectional shape of the first sealing groove 112 is substantially rectangular; the first sealing rubber strip 113 is approximately rectangular in cross section, and the first sealing groove 112 is approximately circular in cross section; the first sealing rubber strip 113 has a substantially trapezoidal cross-sectional shape, and the first sealing groove 112 has a substantially rectangular cross-sectional shape. Thus, after the first sealing rubber strip 113 is assembled in the first sealing groove 112, a certain gap is formed between the two, namely, the deformed gap 114, one side of the first sealant 113 will protrude from the first sealing groove 112 for the glass backlight module 20 to collide against, when the backlight module 20 is assembled on the frame body 10, the backlight module 20 will abut against the portion of the first sealing rubber 113 protruding out of the first sealing groove 112, so that the first sealing rubber 113 is extruded and deformed toward the first sealing groove 112, in the process of deforming the first sealing rubber strip 113, the first sealing rubber strip 113 respectively exerts a certain reaction force on the backlight module 20 and the frame body 10, and the deformation gap 114 is gradually filled, in the state of the backlight module 20 being assembled, the deformation gap 114 therebetween is smaller than the deformation gap 114 before the backlight module 20 is assembled, so as to achieve a fitting relationship with high water tightness.

In order to ensure that the first sealing rubber strip 113 is kept stable in the deformation process, the cross-sectional shapes of the first sealing rubber strip 113 and the first sealing groove 112 can adopt axisymmetric figures, so that the stress of the first sealing rubber strip 113 in the deformation process is more uniform, and the improvement of the water tightness between the first sealing rubber strip and the backlight module 20 and between the first sealing rubber strip and the frame body 10 is facilitated.

In the present embodiment, a fitting relationship between the first sealing rubber strip 113 and the first sealing groove 112 is provided, and the first sealing rubber strip 113 and the first sealing groove 112 are in interference fit, referring to fig. 4, if the cross-sectional shape of the first sealing rubber strip 113 is substantially circular, and the cross-sectional shape of the first sealing groove 112 is substantially rectangular, the diameter of the first sealing rubber strip 113 is slightly larger than or equal to the distance between two opposite side groove walls of the first sealing groove 112, when the first sealing rubber strip 113 is embedded into the first sealing groove 112, two opposite sides of the first sealing rubber strip 113 abut against two opposite side walls of the first sealing groove 112, at this time, the first sealing rubber strip 113 may deform slightly, and the interference fit with the first sealing groove 112 is achieved.
