Protruding. Similarly, the wall portion 501 and the wall portion 502 of the foot pad 5 are disposed on any two opposite sides of the abutting portion 53 and the neck portion 54, and each of the first pushing members 61 and the respective second pushing members 62 are disposed adjacent to the foot. The wall portion 501 of the pad 5 and the opposite sides of the wall portion 502 cause the wall portion 501 and the wall portion 502 of the foot pad 5 to be biased in directions from both sides of the first pressing portion 612 and the second pressing portion 622. Further, the contact region 51 is deformed and protruded.

Referring to FIG. 8 , the second embodiment of the portable electronic device with the foot pad mechanism is substantially the same as the first embodiment. The main difference is that the transmission unit 6 of each foot pad mechanism 4 is not in the foot pad 5 . The force is applied in the direction on both sides of the wall portions 501, 502, and is only applied in one direction in the wall portion 501 of the foot pad 5.

The transmission unit 6 omits the second pusher 62 (see Fig. 4) and includes a fixing plate 64 adjacent to the right wall portion 502 at a fixed setting position. The circuit board 63 omits the second gear 632 (see Fig. 4).

Referring to FIG. 8 and FIG. 10, the processor 634 receives the signal-extension of the height of the foot pad 5, and drives the first gear 631 to rotate clockwise. The first gear 631 drives the first rack portion 611 of the first pushing member 61 toward The left wall portion 501 is displaced in the direction of the wall portion 502 adjacent to the right side, at which time the fixing plate 64 is fixed, that is, the first pushing member 61 approaches each other toward the fixing plate 64, and the foot pad 5 of the foot pad mechanism 4 The abutting portion 53 and the neck portion 54 are pressed by the urging force from the first pressing portion 612, and the contact portion 51 is displaced in a direction away from the bottom wall 21.

Referring to FIG. 8 and FIG. 9, the processor 634 receives the signal-retracting height of the foot pad 5, and drives the first gear 631 to rotate counterclockwise. The first gear 631 drives the first rack portion 611 of the first pushing member 61 toward The left wall portion 501 is displaced in a direction away from the right wall portion 502, at which time the fixing plate 64 is fixed, that is, the first pushing member 61 is moved away from the fixing plate 64, and the foot pad 5 of the foot pad mechanism 4 is used. The abutting portion 53 and the neck portion 54 release the urging force of the first pressing portion 612, and the contact portion 51 is displaced toward the direction adjacent to the bottom wall 21.

It should be noted that the first pushing member 61 of the transmission unit 6 can also be interchanged with the position of the fixing plate 64, or the first pushing member 61 and the fixing plate 64 of the transmission unit 6 are disposed on the front and rear sides of the foot pad 5, or The first pushing member 61 and the fixing plate 64 of the transmission unit 6 are disposed on opposite sides of the foot pad 5 as long as the force is applied to the wall portion 501 of the foot pad 5 in one direction, and the first gear The 631 is disposed corresponding to the first rack portion 611 of the first pusher 61, and can still be implemented.

In summary, the portable electronic device with a foot pad mechanism receives a signal from the temperature sensor 7 or the input interface 8 through the connector 633, and then transmits a signal to the processor 634, and the processor 634 drives The first gear 631 rotates, the first pressing portion 612 urges the wall portion 501 of the foot pad 5 of the foot pad mechanism, and the contact area 51 is displaced away from the bottom wall 21, so that the portable electronic device is presented low before The post-high state is placed on the surface 1 to increase the contact area between the housing 2 and the air, which contributes to heat dissipation of the portable electronic device; furthermore, the user is not easy to fatigue by typing on the keyboard for a long time, and is more suitable for The ergonomic design makes it possible to achieve the purpose of this new type.

The supplementary note is:

1. The foregoing embodiment is to actuate the displacement of the first pusher 61 by means of a gear transmission, but by changing the set position, the gear can also be replaced with other transmission components such as a cam, as long as the first pusher 61 can be driven to displace and push the footpad. The deformation of 5 further changes the distance between the casing 2 and the surface 1.

2. The transmission unit 6 is not limited to the two foot pads 5 disposed at the rear end of the casing 2, and may be changed in number or matched with the foot pads 5 at other positions as needed.

Third, the operation of the transmission unit 6 is controlled by the temperature sensor 7 sensing the temperature of the palm rest area of the housing 2, but its application is not limited thereto, and can also be used with other forms of sensors.
