Description

Electronic device and its fixed module

The present invention relates to a suction cup structure, and more particularly to a suction cup structure for securing an electronic device.

Due to the wide application of the touch input mode, in addition to smart phones and tablets, electronic devices with screens such as notebook computers or televisions have gradually provided touch input functions. However, when the touch input function is added to a notebook computer or a television, the screen weight of the notebook computer or the TV is increased, causing a shift in the center of gravity, which may cause the laptop or the television to fall over. In addition, when the user operates in the touch input mode, it also applies a thrust to the screen of the notebook computer or the television, which generates a torque and causes the notebook computer or the television to fall over. Therefore, there is a need to provide a design that can easily fix an electronic device such as a notebook computer or a television.

The present invention provides a fixed module for solving the problems of the prior art, comprising a driving unit, a sealing unit and a suction cup unit. The sealing unit includes a seal and at least one first elastic recovery element. The drive unit is adapted to apply a thrust to the seal to urge the seal from a first position to a second position. The first spring return element is adapted to apply a restoring force to the seal, the first spring return element pushing the seal from the second position to the first position when the thrust is released. The suction cup unit includes a suction cup holder and a suction cup. The first elastic recovery element is disposed between the sealing member and the suction cup seat, wherein a venting opening is formed on the surface of the suction cup seat, and a deflation passage is formed in the suction cup seat, the venting opening The venting passage is communicated, and the vent opening is opened when the sealing member is in the first position, and the venting opening is closed when the sealing member is in the second position. A suction cup is disposed on the suction cup seat, wherein a vent is formed on the surface of the suction cup, and the vent passage is connected to the vent.

The fixing module of the embodiment of the invention can provide a good fixing for the electronic device, and avoid the electronic device from operating in the touch input mode, because the user applies the thrust of the screen of the notebook computer or the television to cause the notebook computer Or the TV is overturned.

The 331 communicates with the deflation passage 33. The suction cup 32 is disposed on the suction cup holder 31, wherein a vent 332 is formed on the surface of the suction cup 32, and the vent passage 33 communicates with the vent 332. Referring to FIG. 1, a module housing opening 41 is formed at one end of the module housing 40. The driving unit 10, the sealing unit 20 and the suction cup holder 31 are located in the module housing 40, and the suction cup 32 corresponds to the module housing opening 41.

Referring to Figures 2A and 2B, the electric motor 12 drives the cam 11 to rotate between a first orientation (Fig. 2A) and a second orientation (Fig. 2B). In this embodiment, the angular difference between the first orientation and the second orientation is 180 degrees. When the cam 11 is rotated from the first orientation to the second orientation, the cam 11 applies a thrust to the sealing member 21 to urge the sealing member 21 from a first position (FIG. 2A) to a first position. Two positions (Fig. 2B). When the cam 11 is rotated from the second orientation to the first orientation, the cam 11 releases the sealing member 21, and at this time, the thrust is released, and the first elastic restoring member 22 applies a restoring force to the sealing member 21, The seal 21 is pushed back from the second position (Fig. 2B) to the first position (Fig. 2A).

In this embodiment, the driving force is electrically supplied through the electric motor and the cam, and the sealing member 21 is pushed. However, the above disclosure does not limit the present invention, and the electric motor can be replaced by other drivers or manual devices. The cam can also be replaced by other forms of transmission.

Referring to Figures 2A, 2B, when the seal 21 is in the first position, the seal 21 opens the vent 331. When the seal 21 is in the second position, the seal 21 closes the vent 331.

The sealing member 21 includes an abutting member 211 and a sealing member 212. The abutting member 211 is coupled to the sealing member 212. The cam 11 abuts the abutting member 211.

The first flange 214 surrounds the sealing portion 213, and the first elastic recovery element 22 abuts the first flange 214.

In this embodiment, the sealing portion 213 has a cup shape and has a notch 215, and the abutting member 211 is inserted into the notch 215 to connect the sealing portion. Piece 212. The abutting member 211 includes an abutting plate 216 and a post 217. The post 217 is coupled to the center of the abutting plate 216. The cam 11 abuts the abutting plate 216. The post 217 extends into the recess 215. in.

The suction cup holder 31 includes a second flange 311. The first elastic recovery element 22 is disposed between the first flange 214 and the second flange 311.

The chuck unit 30 further includes a second elastic restoring element 34 disposed between the second flange 311 and one of the housing abutment portions 42 of the module housing 40.

In an embodiment, when the sealing member 21 is pushed from the first position to the second position (FIG. 2B), the sealing member 21 pushes the suction cup unit 30 to extend the suction cup 32 to the module. The housing opening 41 absorbs a fixed surface. At this time, the air vent 331 is closed, and the suction force between the suction cup 32 and the fixed surface is maintained. When the sealing member 21 is returned from the second position to the first position, the air vent 331 is opened, the suction force between the suction cup 32 and the fixed surface is released, and the second elastic recovery member 34 pushes the suction cup unit 30. The suction cup 32 is returned to the module housing opening 41.

In a variant, the suction cup can also be fixedly exposed outside the opening of the module housing, and the second elastic recovery element can be omitted. The above disclosure does not limit the invention.

Referring to Fig. 3, there is shown an electronic device 9 to which a fixed module 1 of an embodiment of the present invention is applied, which includes a device housing 91. The device housing 91 has a device housing bottom surface 92. A device housing opening 93 is formed in the device housing bottom surface 92. The fixing module 1 is disposed in the device housing 91, and the device housing opening 93 corresponds to the module housing opening 41. When the seal 21 is pushed from the first position to the second position, the suction cup 32 protrudes from the device The bottom surface 92 of the housing absorbs the fixed surface. When the seal 21 is returned from the second position to the first position, the suction cup 32 returns to the device housing 91. The electronic device 9 can be a notebook computer, or other portable electronic device, or a relatively large electronic device such as a television.

In a variant, the module housing can be omitted, and the drive unit, the sealing unit and the suction cup unit are directly disposed in the device housing. In another variation, the module housing can be integrally formed with the device housing.

The fixing module of the embodiment of the invention can provide a good fixing for the electronic device, and avoid the electronic device from operating in the touch input mode, because the user applies the thrust of the screen of the notebook computer or the television to cause the notebook computer Or the TV is overturned.
