Description

Technical Field

[0001] This invention relates to a laptop computer and a sensing component, and more particularly to a laptop computer and a sensing component equipped with a sensing component. Background Technology

[0002] In recent years, laptops have become indispensable tools for modern people in their work and life due to their ability to balance computing performance and portability. When managing power, the operating system of a laptop usually enters either a user-friendly operating mode or a power-saving sleep mode depending on whether the screen is open or closed, in order to control the laptop's power consumption.

[0003] Today's users have increasingly diverse needs for laptop mode switching. For example, users want to be able to switch their laptops into either laptop or tablet mode depending on their purpose and needs. However, current laptop operating systems can only detect whether the screen is open or closed to put the laptop into operating or sleep mode, meaning current laptops can only switch between two modes and cannot meet the diverse needs of users. Summary of the Invention

[0004] The present invention provides a laptop computer and a sensing component to meet the user's needs for switching between various modes of the laptop computer.

[0005] An embodiment of the present invention discloses a laptop computer comprising a host, a display, a first pivot, a second pivot, a sensing component, and a controller. The first pivot is rotatably connected to the host. The second pivot is rotatably connected to the display. The first pivot and the second pivot are connected so that the first pivot and the second pivot rotate synchronously. The sensing component is disposed within the host and includes a pressure sensor and a cam. The cam is fitted onto the first pivot and presses against the pressure sensor. The controller is electrically connected to the pressure sensor. When the display rotates relative to the host via the second pivot, the first pivot drives the cam to rotate, causing the cam to press against the pressure sensor at different angles, allowing the pressure sensor to sense different pressure values ​​and transmit these different pressure values ​​to the controller. The controller determines the angle between the display and the host based on the different pressure values.

[0006] Another embodiment of the present invention discloses a sensing component disposed within the main body of a laptop computer, comprising a pressure sensor and a cam. The cam is fitted onto the pivot of the laptop computer and presses against the pressure sensor. When the cam rotates via the pivot of the laptop computer, the cam presses against the pressure sensor at different angles, causing the pressure sensor to sense different pressure values, which are then transmitted to the controller of the laptop computer. The controller of the laptop computer determines the angle between the laptop computer's display and the main body based on the different pressure values.

[0007] According to the laptop computer and sensing component of the above embodiment, since the laptop computer is equipped with a pressure sensor and a cam, and the cam is disposed on a second pivot, and the second pivot rotates synchronously with the first pivot, when the display rotates relative to the host, the pressure sensor can receive different pressure values ​​caused by the rotation of the cam, and transmit the different pressure values ​​to the controller, so that the controller can determine the angle between the display and the host according to the different pressure values, thereby enabling the display to be in a laptop mode (off state), a working state, a tablet mode, or a stand mode. In this way, the user's needs for switching between multiple modes of the laptop computer can be met, and there is no need to install multiple additional sensors.

[0008] The above description of the invention and the following description of the embodiments are used to demonstrate and explain the principles of the invention, and to provide a further explanation of the claims of the invention. Attached Figure Description

[0016] Please see Figures 1 to 4 . Figure 1 This is a perspective view of a laptop computer according to an embodiment of the present invention. Figure 2 for Figure 1 A magnified 3D diagram of a portion of a laptop computer. Figure 3 for Figure 1 A block diagram illustrating the connection relationship between the sensing components and the controller in a laptop computer.

[0017] The laptop computer 10 of this embodiment includes a host 11, a display 12, an assembly 13, a first pivot 14, a second pivot 15, a transmission component 16, a sensing component 17, and a controller 18. The assembly 13 is disposed on one side of the host 11 and the display 12. The first pivot 14, the second pivot 15, and the transmission component 16 are disposed on the assembly 13. The first pivot 14 is rotatably connected to the host 11. The second pivot 15 is rotatably connected to the display 12.

[0018] In detail, the main unit 11 has a first mounting portion 111. A first pivot 14, with its end away from the assembly 13, passes through the first mounting portion 111. The display 12 has a second mounting portion 121. A second pivot 15, with its end away from the assembly 13, passes through the second mounting portion 121. The transmission member 16 is, for example, a gear, but is not limited thereto. The first pivot 14 and the second pivot 15 are connected by engagement with the transmission member 16, so that the first pivot 14 and the second pivot 15 rotate synchronously.

[0019] The sensing component 17 is disposed within the main unit 11 and includes a circuit board 171, a pressure sensor 172, a cam 173, and an elastic pad 174. The pressure sensor 172 is electrically connected to the circuit board 171. The cam 173 is fitted onto the first pivot 14. The elastic pad 174 is fitted against the pressure sensor 172 and located between the cam 173 and the pressure sensor 172, so that the cam 173 presses against the elastic pad 174 to smoothly transmit pressure to the pressure sensor 172. The elastic pad 174 is, for example, made of rubber. The controller 18 is electrically connected to the pressure sensor 172 via the circuit board 171. The pressure sensor 172 transmits different pressure values ​​to the controller 18 via the circuit board 171.

[0020] In this embodiment, when the display 12 rotates relative to the host 11 via the second pivot 15, the first pivot 14 drives the cam 173 to rotate, so that the cam 173 presses against the pressure sensor 172 at different angles, causing the pressure sensor 172 to sense different pressure values ​​and transmit the different pressure values ​​to the controller 18. The controller 18 determines the angle between the display 12 and the host 11 based on the different pressure values.

[0021] Specifically, when the controller 18 determines that the angle between the display 12 and the host 11 is, for example, greater than or equal to 0 degrees and less than or equal to 30 degrees, the controller 18 controls the display 12 to be in a turned-off state, so that the display 12 turns off the screen and enters a sleep or power-saving mode. When the controller 18 determines that the angle between the display 12 and the host 11 is, for example, greater than 30 degrees, the controller 18 controls the display 12 to be in a working state, so that the display 12 displays an image.

[0022] Furthermore, when the controller 18 determines that the angle between the display 12 and the host 11 is, for example, greater than 30 degrees and less than or equal to 120 degrees, the controller 18 controls the display 12 to be in laptop mode, allowing the user to operate the laptop 10 via a keyboard (not shown). When the controller 18 determines that the angle between the display 12 and the host 11 is, for example, greater than 120 degrees and less than or equal to 250 degrees, the controller 18 controls the display 12 to be in tablet mode, allowing the user to lay the display 12 flat and operate it via touch. When the controller 18 determines that the angle between the display 12 and the host 11 is, for example, greater than 250 degrees and less than or equal to 280 degrees, the controller 18 controls the display 12 to be in stand mode, allowing the user to, for example, watch videos.

[0023] In this embodiment, since the laptop 10 is equipped with a pressure sensor 172 and a cam 173, and the cam 173 is disposed on a second pivot 15, and the second pivot 15 rotates synchronously with the first pivot 14, when the display 12 rotates relative to the host 11, the pressure sensor 172 can receive different pressure values ​​caused by the rotation of the cam 173, and transmit the different pressure values ​​to the controller 18, so that the controller 18 can determine the angle between the display 12 and the host 11 according to the different pressure values, thereby enabling the display 12 to be in a closed state, a working state (laptop mode), a tablet mode, or a stand mode. In this way, the user's needs for switching between multiple modes of the laptop 10 can be met, and there is no need to install multiple additional sensors.

[0024] In this embodiment, the laptop computer 10 is provided with assembly 13, but this is not a limitation. In other embodiments, the laptop computer may not be provided with assembly.

[0025] In this embodiment, the sensing component 17 is provided with an elastic pad 174, and the cam 173 presses against the elastic pad 174 to transmit pressure to the pressure sensor 172, but this is not a limitation. In other embodiments, the sensing component may not be provided with an elastic pad, and the cam may directly press against the pressure sensor.

[0026] In this embodiment, the laptop 10 can also determine, for example, automatically reduce the volume of the microphone (not shown) when the angle between the display 12 and the host 11 is greater than or equal to 10 degrees and less than or equal to 30 degrees.

[0027] In this embodiment, the laptop 10 can also integrate the aforementioned angle information into the application programming interface (API) so that third-party applications can develop new functions using the aforementioned angle information.

[0028] Please refer to the following: Figures 4 to 7 . Figure 5 for Figure 1 A magnified cross-sectional view of a portion of a laptop computer where the display rotates relative to the host. Figure 6 for Figure 1 An enlarged cross-sectional view of another part of a laptop computer where the display rotates relative to the host. Figure 7 for Figure 1 An enlarged cross-sectional view of another part of a laptop computer where the display rotates relative to the host.

[0029] like Figure 4 As shown, the angle between the monitor 12 and the host 11 is 0 degrees, meaning that the monitor 12 completely covers the host 11. At this time, the controller 18 controls the monitor 12 to be in the off state, so that the monitor 12 turns off the screen and enters sleep or power-saving mode.

[0030] In this embodiment, when the user rotates the display 12 in direction A, the cam 173 is driven to rotate in direction B. At this time, the cam 173, due to its rotation, presses against the pressure sensor 172 at different angles, causing a change in the pressure value sensed by the pressure sensor 172. Then, the pressure sensor 172 transmits the change in pressure value to the controller 18, so that the controller 18 determines the angle between the display 12 and the host 11 based on the change in pressure value.

[0031] For example, such as Figure 5 As shown, the controller 18 determines that the angle R between the display 12 and the host 11 is, for example, 120 degrees. At this time, the controller 18 controls the display 12 to be in laptop mode, allowing the user to operate the laptop 10 via the keyboard. Figure 6As shown, the controller 18 determines that the angle R between the display 12 and the host 11 is, for example, 300 degrees. Figure 7 As shown, the controller 18 determines that the display 12 has been completely flipped to the other side of the host 11.

[0032] According to the laptop computer and sensing component of the above embodiment, since the laptop computer is equipped with a pressure sensor and a cam, and the cam is disposed on a second pivot, and the second pivot rotates synchronously with the first pivot, when the display rotates relative to the host, the pressure sensor can receive different pressure values ​​caused by the rotation of the cam, and transmit the different pressure values ​​to the controller, so that the controller can determine the angle between the display and the host according to the different pressure values, thereby enabling the display to be in a laptop mode (off state), a working state, a tablet mode, or a stand mode. In this way, the user's needs for switching between multiple modes of the laptop computer can be met, and there is no need to install multiple additional sensors.
