Referring to fig. 1 to 5, the present embodiment provides a television set including a display module having a display panel 10, a power supply electrically connected to the display module, and a control circuit. The television further includes a module bracket 20 for fixing the display module, and a device bracket 30 for accommodating the power supply and the control circuit and fixing the module bracket 20. It should be noted that the module holder 20 and the device holder 30 in this embodiment may also be suitable for an advertisement machine or other equipment, especially for outdoor use.

The device bracket 30 includes a device upper shell 31 and a device lower shell 32 which are arranged up and down, the device upper shell 31 and the device lower shell 32 are enclosed to form a device containing cavity 33, the lower end of the device upper shell 31 is sleeved on the outer side of the upper end of the device lower shell 32 or inserted on the inner side of the upper end of the device lower shell 32, and the lower end of the device upper shell 31 and the upper end of the device lower shell 32 are in watertight connection through foamed glue 40. A gap is left between the lower end of the device upper case 31 and the upper end of the device lower case 32, and the foam rubber 40 is filled in the gap to realize watertight connection between the lower end of the device upper case 31 and the upper end of the device lower case 32. The filling amount of the foamed rubber 40 may be set by those skilled in the art according to the opposite area sizes of the lower end portion of the device upper case 31 and the upper end portion of the device lower case 32, as long as the watertight connection of the lower end portion of the device upper case 31 and the upper end portion of the device lower case 32 is achieved.

In the illustrated embodiment, the lower end of the device upper case 31 is fitted inside the upper end of the device lower case 32.

In the assembling process, the dispensing apparatus sprays the foaming glue 40 on the outer side surface of the lower end portion of the device upper case 31 or the inner side surface of the upper end portion of the device lower case 32, and then the device upper case 31 is closed downward with the device lower case 32 so that the lower end portion of the device upper case 31 is opposite to the upper end portion of the device lower case 32, and at this time, the foaming glue 40 simultaneously connects the device upper case 31 and the device lower case 32. The foaming glue 40 is cured to make the device upper case 31 and the device lower case 32 watertight connected.

Because the foaming adhesive 40 is foamed when being sprayed and can change the shape according to the surrounding side environment, or can fill the gap between the two structures, the two structures can be connected seamlessly after being cured. The foamed rubber 40 is used instead of the rubber ring, and due to the characteristics of the foamed rubber 40, the influence of the deformation of the two structures during the assembly process on the sealing performance does not need to be considered. That is, no matter what kind of deformation occurs during the assembly process, seamless connection of the two structures can be ensured, thereby ensuring water tightness between the two structures. Therefore, in this embodiment, regardless of the deformation of the device upper case 31 and the device lower case 32, the foaming glue 40 is automatically filled in the gap between the device upper case 31 and the device lower case 32, thereby achieving the watertight connection after the foaming glue 40 is cured.

The foaming glue 40 is filled between the device upper case 31 and the device lower case 32, and has a ring shape. In this embodiment, the horizontal projection of the upper housing 31 is rectangular, and correspondingly, the horizontal projection of the foam rubber 40 is rectangular and annular.

The lower end of the upper device shell 31 has an annular groove recessed inward and extending to the lower surface thereof, and the upper end of the lower device shell 32 is fitted in the groove.

Firstly, the arrangement of the groove can improve the elastic modulus of the structure and increase the structural strength. Secondly, the provision of the groove can provide a location for the assembly of the device upper case 31 and the device lower case 32, and in particular, the upper groove wall of the groove restricts the upward movement of the device lower case 32, thereby setting the position of the assembly. In addition, the upper end of the device lower shell 32 is located outside the device upper shell 31, and the arrangement of the groove enables the outer surface of the upper end to be flush with the outer surface of the device upper shell 31, so that the appearance is beautified.

In this embodiment, referring to fig. 4, the device holder 30 further includes a fastening member for connecting the lower end of the device upper case 31 and the upper end of the device lower case 32. In this embodiment, the fastener is a screw. The figures do not show the structure of the fastener, showing the attachment holes in mating connection with the fastener. The connecting hole is opened in the groove. The connection holes are provided in a plurality of and spaced apart from each other, and preferably, the connection holes opened at the upper end portion of the device lower case 32 are countersunk holes 2111 to achieve a screw hiding effect. The device upper shell 31 and the device lower shell 32 are firmly connected by screws.

In this embodiment, the lower end of the upper case 31 is a folded plate, which includes a first side plate and a second side plate that are vertically disposed, and the first side plate is recessed inwards to form a groove. The first sideboard is screwed with the upper end of the device lower case 32, and the second sideboard leaves a gap with the device lower case 32 for filling the foaming glue 40. In other embodiments, the foam 40 may also fill the groove or both the groove and the gap.

Referring to fig. 5, the lower end of the device upper shell 31 is provided with an annular glue guiding groove 311. In the illustrated embodiment, the cross-section of the glue guiding groove 311 is circular and the center of gravity is located outside the glue guiding groove 311. With this arrangement, the inlet of the glue guide slot 311 is at the widest cross-sectional position and then tapers inward, thereby guiding the foamed glue 40 to gather toward the bottom of the slot. Lead the setting of gluey groove 311, increased the volume of foaming rubber 40, more important, lead the setting of gluey groove 311, guide foaming rubber 40 and preferentially gather in leading gluey groove 311, be favorable to ensureing the watertight connection of leading gluey groove 311 department. In addition, under the small deformation between the device upper shell 31 and the device lower shell 32, the foaming glue 40 in the glue guide groove 311 can also be timely supplemented to the deformed position.

Referring to fig. 5 again, the upper end of the device lower shell 32 is correspondingly provided with a glue injection hole 321 at the position of the glue guide slot 311. The dispensing apparatus sprays the foaming glue 40, and then assembles the device upper case 31 and the device lower case 32. During the assembly process, if it is found that the amount of the foaming adhesive 40 between the device upper case 31 and the device lower case 32 is insufficient, the foaming adhesive 40 may be injected inwardly through the injection hole 321. As will be understood by those skilled in the art, the glue injection hole 321 is used to supplement a small amount of the foaming glue 40, and thus the diameter of the glue injection hole 321 is small. In addition, the smaller diameter of the hole is also beneficial to reducing the outflow of the foaming glue 40 through the injection hole.

In this embodiment, the device upper shell 31 and the device lower shell 32 are connected to form a device cavity 33 with an upward opening.

The module holder 20 is placed in the device accommodating chamber 33, and the upper surface thereof is in watertight connection with the upper cavity wall of the device accommodating chamber 33 through the foamed rubber 40 and closes the opening of the device accommodating chamber 33.
