In on the medial surface of keypad 200.
In addition, in preferred embodiment provided by the utility model, as shown in Fig. 2, being pressed along this in the key hole 11
The one side edge of keyhole 11 is arranged in sequence with multiple keypads 200, and between having between the two neighboring keypad 200
Gap.
Using the above scheme, by taking the display devices such as television set as an example, number of keys generally has multiple, including volume+key, sound
Amount-key, program+key, program-key, Menu key, power switch key etc., when number of keys has it is multiple when, the press-key structure
Multiple keypads 200 can be set in key hole 11, and each keypad 200 corresponds to a function button, and multiple
The keypad 200 is arranged in order along the one side edge of the key hole 11, has gap between two neighboring keypad 200,
So that the keypad 200 can be moved relative to shell 10.
It should be noted that the press-key structure can be in the layout of with appearance space according to display device on the shell 10
Suitable position at, illustrate the preferred embodiment of press-key structure provided by the utility model below.
In the prior art, for large-scale display devices such as television sets, heat dissipation pore structure would generally be set on shell 10,
It radiates to complete machine；And also increasingly (remote controler can be realized the keypress function on display technology field, shell 10 for reduction
Keypress function) so that complete machine appearance is more succinct.But in current display device, button is still both exposed to shell 10
On, it is unfavorable for complete machine tailored appearance.
Based on the above, the display device provided in the utility model embodiment, in order to be more advantageous to complete machine tailored appearance,
It is reasonable using, it can be achieved that by display device that heat dissipation pore structure on the keypad 200 and display device shell 10 has been carried out
On button " hiding " purpose.
Specifically, in the present embodiment, as shown in Fig. 2, the shell 10 is equipped with heat dissipation pore structure, the heat emission hole knot
Structure includes the open region being opened on the shell 10, and the one side edge in the open region, along the open region is successively
At least two strip boards 300 are arranged with, there is gap between the two neighboring strip board 300, to form multiple heat emission holes；Its
In, the button circuit board 100 is set to the medial surface side of shell 10, and is located at and the position corresponding to the heat emission hole
It sets, the open region forms the key hole 11；At least one strip board 300 is interior in multiple strip boards 300
Side is provided with the press-key triggering structure 201, that is, forms the keypad 200.
Using the above scheme, since in the heat dissipation pore structure that is arranged in display device multiple would generally be arranged in shell 10
Shape plate 300 has gap between two neighboring strip board 300, and forms heat emission hole, therefore, it is described can multiple of arrangement above
The entire open region of shape plate 300 can be considered the key hole 11, and the strip board 300 can be considered a cantilever design, that is, can incite somebody to action
At least one strip board as the keypad 200 use, the medial surface of at least one strip board come be arranged by
Key trigger architecture 201, and the button circuit board 100 is set in heat dissipation pore structure corresponding position, as a result, by press-key structure with dissipate
Hot hole structure assembly realizes keypress function using the heat dissipation pore structure, in this way, the press-key structure can not only be used for heat emission hole knot
Structure radiates to complete machine, also so that press-key structure can be hidden in heat dissipation pore structure, without individually being set again in 10 other positions of shell
The structures such as key hole 11 and keypad 200 are set, are not easy to be found so that complete machine appearance is more succinct, saves cost.
It should be noted that using the above scheme, press-key structure is integrated at heat dissipation pore structure to reduce, to the work(that radiates
It can have an impact, in actual design process, the press-key structure can be designed in the bottom side of heat dissipation pore structure, it is,
The press-key triggering structure 201 is designed to the end of the strip board 300, the button circuit board 100 is arranged in correspondence with
The end of the strip board 300, evacuation opens the heat emission hole as possible as a result, to reduce the influence to heat dissipation；In addition, relative to
Heat dissipation pore structure in the prior art can increase the quantity of the heat emission hole and the strip board 300, to reduce to heat dissipation
It influences；In addition, also the heat emission hole symmetrical configuration can be distributed on shell 10, to improve heat-sinking capability.
In addition, in the present embodiment, it is preferred that as shown in Fig. 2, multiple strip boards 300 include：
It is provided at least two first strip boards 301 of the press-key triggering structure 201；
And at least two second strip boards 302 of the press-key triggering structure 201 are not set；
Wherein, at least one second strip board 302 is equipped between adjacent two first strip boards 301.
Using the above scheme, since the gap between each stripe board in the usually described heat dissipation pore structure is smaller, in order to full
The installation space demand of the sufficient button circuit board 100, the strip board 300 for being provided with the press-key triggering structure 201 are (i.e. described
First strip board 301) and be not arranged the press-key triggering structure 201 strip board 300 (i.e. described second strip board 302) answer between
At least one second strip board 302 should be set between setting, the first strip board of each two 301.
Of course, it should be understood that the above is only provide it is a kind of by press-key structure be integrated in it is described heat dissipation pore structure at it is excellent
It selects mode, in practical applications, be not limited thereto, described can not also be arranged between two neighboring first strip board 301
Two strip boards 302.
In addition, as shown, in the present embodiment, it is preferred that the lateral surface of the keypad 200 is equipped with for identifying
The coating 400 of button；And/or the mark for marking button is equipped with the position of 200 face of the keypad on the shell 10
Remember structure 500.
Using the above scheme, when the press-key structure being hidden in the heat dissipation pore structure, can by be used as by
Brush applied coating 400, the on the housing 10 modes such as setting flag structure 500 are applied in the strip board 300 of keypad 200, to keypress function
It is marked.
In addition, additionally provide a kind of display device in the utility model embodiment, including shell 10 and press as described above
