[0026] Furthermore, the shutter mechanism 7 includes a horizontal baffle 71, the outer end of which is inserted into the guide rail 62 of the horizontal groove 61 of the rectangular protruding platform 6; guide wheels 76 are installed on both sides of the bottom surface of the inner end of the horizontal baffle 71; a connecting vertical plate 74 is provided on the outer middle side of the top surface of the horizontal baffle 71, the top of the connecting vertical plate 74 is inserted through the slide groove 52 on the bottom surface of the keyboard 5, and a nut 73 is provided on the top of the connecting vertical plate 74, and the nut 73 is screwed on the horizontal screw rod 72, which is installed on two screw rod bearings, and the two screw rod bearings are respectively installed at the middle ends of the left half or right half of the bottom surface of the keyboard 5; the outer end of the horizontal screw rod 72 is inserted through the through hole on the corresponding side of the keyboard shell 3 to the outside, and a screw cap 77 is installed on the outer end of the horizontal screw rod 72.
[0027] Furthermore, guide rail convex strips 711 are provided on both sides of the top surface of the horizontal baffle 71 to match with the guide rail 62 of the horizontal channel 61 in the rectangular convex foot platform 6 .
[0028] Furthermore, the screw cap 77 is replaced by a micro motor 9, and the micro motor 9 is connected to a PLC controller 10 through a wire. The PLC controller 10 is installed on one side of the bottom surface 5 of the keyboard, and the PLC controller 10 is connected to a temperature sensor 11 through a wire.
[0029] The working principle of the utility model is described as follows:
[0030] The difference between this design and the traditional keyboard is that this design has a rectangular heat dissipation port 5 on the bottom surface of the traditional keyboard. The rectangular heat dissipation port 5 is large, so it can quickly communicate with the outside world, so that the heat can be quickly dissipated. However, if the heat accumulation of the keyboard does not form a high temperature, the large rectangular heat dissipation port 5 is easy to cause foreign matter to enter, and the components in the keyboard are easily affected by the outside world and damaged.
[0031] Therefore, our company has set up a shielding mechanism that can form a shield. When heat dissipation is needed, the shield can be opened to expose the rectangular heat dissipation port 5 to ensure that the inner cavity of the keyboard is connected to the outside during this period, so as to quickly dissipate heat. In order to control costs, the first design idea is to use manual operation, and the second design idea is to add an electric operation, so as to form two high and low product structure versions, which is easy for later sales and cost control.
[0032] Embodiment 1: Figure 1-Figure 4As shown, a manually operated low-version shield mechanism is adopted. During use, after the keyboard is used for a long time, heat accumulates inside it. At this time, the user uses both hands to twist the screw caps 77 installed on both sides of the keyboard, and the screw caps 77 drive the horizontal screw rod 72 to rotate, and the horizontal screw rod 72 drives the nut 73 thereon to move horizontally. Since the nut 73 is connected to the connecting vertical plate 74, and the connecting vertical plate 74 is inserted in the slide groove 52 in the middle of the bottom surface 5 of the keyboard, the rectangular slide groove 52 forms a limit, which limits the rotation of the connecting vertical plate 74 with the nut 73. At the same time, the slide groove 52 also limits the stroke of the connecting vertical plate 74, thereby limiting the stroke of the nut connected to the connecting vertical plate 74 on the horizontal screw rod. The connecting vertical plate 74 moves horizontally toward the outside, driving the horizontal baffle 71 connected thereto to move toward the outside, and the guide rail convex strip 711 on the horizontal baffle 71 moves in the guide rail 62 of the horizontal groove 61 of the rectangular convex foot platform 6, and the outer end of the horizontal baffle 71 protrudes outside the rectangular convex foot platform 6; in this way, the horizontal baffles 71 on the two shielding mechanisms 7 move toward the outside, thereby exposing the rectangular heat dissipation opening 5 to achieve heat dissipation. Then, when closing, just turn the screw cap 77 in the opposite direction.
[0033] Embodiment 2: Figure 5 As shown, a high-version shutter mechanism with electric operation is adopted. The screw cap 77 is replaced by a micro motor 9, which is connected to a PLC controller 10 through a wire. The PLC controller 10 is installed on one side of the keyboard bottom surface 5, and the PLC controller 10 is connected to a temperature sensor 11 through a wire. A motor button is installed in front of a rectangular convex foot platform 6 on the left side of the bottom surface of the keyboard bottom surface 5 to control the forward and reverse rotation of the micro motor 9.
[0034] In this way, when the temperature sensor 11 detects the temperature and it reaches the set critical temperature, the PLC controller 10 starts the micro motor 9. Alternatively, the motor button can be pressed to control the micro motor 9 to control the horizontal screw rod to rotate, and the other steps are the same as those in the first embodiment.
[0035] In this design, a screen 53 is provided on the rectangular heat dissipation port 5 to prevent foreign matter from entering, so as to prevent foreign matter from entering the keyboard during heat dissipation.
[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
