TECHNICAL FIELD

This application relates to the field of electronic device technologies, and in particular, to a notebook computer.

BACKGROUND

A rotating shaft of a notebook computer is a key component that connects a display screen of the notebook computer and a base of the notebook computer. Specifically, a rotating shaft support is disposed on the display screen of the notebook computer, and a rotating shaft support is also disposed on the base of the notebook computer. During assembling, the rotating shaft support on the display screen of the notebook computer and the rotating shaft support on the base of the notebook computer are assembled with a same rotating shaft, so that the display screen of the notebook computer and the base of the notebook computer can be assembled.

However, to ensure reliability and stability of the rotating shaft of the notebook computer, for a large-sized notebook computer, a relatively large fixing area is usually required to fix a rotating shaft support of the rotating shaft, but space on the display screen of the notebook computer for disposing the rotating shaft support is relatively limited. Consequently, there is insufficient space for designing a rotating shaft on a display screen of an existing notebook computer.

SUMMARY

To resolve the foregoing technical problem, embodiments of this application provide a notebook computer, so as to resolve a problem that there is insufficient space for designing a rotating shaft on an existing notebook computer.

When the rotating shaft support extends from two sides of the display screen of the notebook computer to the middle to a region in which the drive circuit board is located, at least a partial region of the second rotating shaft support is disposed under the drive circuit board, so that the drive circuit board and the second rotating shaft support share the partial region, to resolve a problem that a disposing location of the rotating shaft support conflicts with a disposing location of the drive circuit board when the rotating shaft support extends from the two sides of the display screen of the notebook computer to the middle to the region in which the drive circuit board is located. Therefore, an entire size of the notebook computer is not affected because an area of a bezel region of the display screen of the notebook computer is not increased, and costs are relatively low because the drive circuit board does not need to be modified.

With reference to any one of the foregoing possible implementations of the first aspect, in an eighth possible implementation, a thickness of a preset region of the second rotating shaft support is less than a thickness of the first rotating shaft support, to increase strength of the first rotating shaft support, and improve stability between the rotating shaft support and the rotating shaft.

DESCRIPTION OF EMBODIMENTS

As shown in the background, there is a problem that there is insufficient space for designing a rotating shaft on a display screen of an existing notebook computer.

Specifically, the display screen of the existing notebook computer includes a display region and a bezel region surrounding the display region. A drive circuit board and a rotating shaft support that is located on two sides of the drive circuit board and that is configured to fix a rotating shaft are disposed in the bezel region. To ensure stability of the rotating shaft that connects the display screen and a base of the notebook computer, the rotating shaft support configured to fix the rotating shaft usually extends from left and right sides of the notebook computer to a direction of the drive circuit board, so as to increase an area for fixing the rotating shaft support.

However, because an area of the bezel region of the display screen of the notebook computer is relatively limited, when the rotating shaft support extends from the direction of the drive circuit board to a region in which the drive circuit board is located, a disposing location of the rotating shaft support conflicts with a disposing location of the drive circuit board.

In view of this, an embodiment of this application provides a notebook computer. As shown inFIG. 1, the notebook computer includes a display screen1, a base2, a rotating shaft3that connects the display screen1and the base2, a rotating shaft support4that is disposed inside a housing of the display screen1and that is connected to the rotating shaft3in an assembly manner, and a drive circuit board disposed inside the housing of the display screen1. As shown inFIG. 2, the rotating shaft support4includes a first rotating shaft support41and a second rotating shaft support42, a projection of the drive circuit board5and a projection of the first rotating shaft support41do not overlap on a plane on which the display screen1is located, and the projection of the drive circuit board5and a projection of the second rotating shaft support42at least partially overlap on the plane on which the display screen1is located.

Specifically, in an embodiment of this application, as shown inFIG. 3, a bezel region of the display screen1includes two rotating shaft supports4and the two rotating shaft supports4are configured to be respectively assembled with the rotating shaft3on two ends of the bezel region.

It should be noted that, in this embodiment of this application, the first rotating shaft support41is a primary bearing support and is configured to bear main weight of the housing of the display screen1and the rotating shaft3, and the second rotating shaft support42is a secondary bearing support and is configured to extend in a direction from the first rotating shaft support41to the second rotating shaft support42, to reduce a rotating shaft span between two sides of the housing of the display screen1, and increase an area for fixing the rotating shaft support4and the housing of the display screen1.

To increase a bearing capability of the first rotating shaft support41and improve stability between the rotating shaft3and the rotating shaft support4, in an embodiment of this application, a thickness of a preset region of the second rotating shaft support42is less than a thickness of the first rotating shaft support41. The preset region may be an entire region of the second rotating shaft support42, or may be a partial region in the second rotating shaft support42. This application imposes no limitation thereto provided that the preset region completely covers an overlapping region between the second rotating shaft support42and the drive circuit board.

It should be noted that, in this embodiment of this application, the thickness of the first rotating shaft support41may be the same as or different from a thickness of a rotating shaft support in the prior art. This is not limited in this application, and specifically depends on a situation.

It can be learned that, on the notebook computer provided in this embodiment of this application, the rotating shaft support4includes two parts: the first rotating shaft support41and the second rotating shaft support42, and the projection of the drive circuit board and the projection of the second rotating shaft support42at least partially overlap on the plane on which the display screen1is located. When the rotating shaft support4extends from two sides of the display screen1of the notebook computer to the middle (that is, in a direction X) to a region in which the drive circuit board is located, at least a partial region of the second rotating shaft support42is disposed under the drive circuit board5, so that the drive circuit board5and the second rotating shaft support42share the partial region, to resolve a problem that a disposing location of the rotating shaft support4conflicts with a disposing location of the drive circuit board5when the rotating shaft support4extends from the two sides of the display screen1of the notebook computer to the middle to the region in which the drive circuit board5is located. Therefore, an entire size of the notebook computer is not affected because an area of the bezel region of the display screen1of the notebook computer is not increased, and costs are relatively low because the drive circuit board5does not need to be modified.

It should be noted that, in this embodiment of this application, still as shown inFIG. 1, a housing of the base2includes another rotating shaft support6, and is assembled with the rotating shaft3by using the another rotating shaft support6. There is relatively sufficient available space for the rotating shaft support in the housing of the base. Therefore, in an embodiment of this application, the rotating shaft support in the housing of the base may be a rotating shaft support with a same thickness at all parts, to further improve fixing strength of the rotating shaft support. However, this application imposes no limitation thereto. In another embodiment of this application, when there is limited available space for the rotating shaft support in the housing of the base, a structure of the rotating shaft support provided in this embodiment of this application may be used for replacement, and this specifically depends on a situation.

Based on the foregoing embodiment, in an embodiment of this application, that the projection of the drive circuit board and the projection of the second rotating shaft support42at least partially overlap on the plane on which the display screen1is located may be: The drive circuit board5and the second rotating shaft support42partially overlap in the direction from the first rotating shaft support41to the second rotating shaft support42(that is, the direction X), or the drive circuit board5completely covers or partially covers the second rotating shaft support42in the direction from the first rotating shaft support41to the second rotating shaft support42. This is not limited in this application, and specifically depends on a situation.

Based on any one of the foregoing embodiments, in an embodiment of this application, as shown inFIG. 4, the first rotating shaft support41includes: a first body part411fixedly connected to the housing of the display screen1and a first fastener412that is in an integrated structure with the first body part411, and the second rotating shaft support42includes a second body part421fixedly connected to the housing of the display screen1and a second fastener422that is in an integrated structure with the second body part421. The first body part411and the second body part421are fixedly connected to the housing of the display screen1, and the first fastener412is connected to the rotating shaft3in an assembly manner.

Specifically, in an embodiment of this application, the first fastener412is a bent arm, the bent arm includes a center through-hole, and the rotating shaft3passes through the center through-hole, to assemble and connect the first fastener412and the rotating shaft3.

Based on the foregoing embodiment, in an implementation of this application, as shown inFIG. 4andFIG. 6, the second fastener422is connected to the rotating shaft3in an assembly manner, to increase fixing strength of the rotating shaft support4and the rotating shaft3. Specifically, still as shown inFIG. 4andFIG. 6, when the second fastener422is connected to the rotating shaft3in an assembly manner, in an embodiment of this application, the second fastener422includes a center through-hole, and the rotating shaft3passes through the center through-hole, to assemble and connect the second fastener422and the rotating shaft3.

In another implementation of this application, the second fastener422is fixedly connected to the first body part411. Specifically, as shown inFIG. 5andFIG. 7, when the second fastener422is fixedly connected to the first body part411, the second fastener422is connected to the first body part411through riveting or welding, to fixedly connect the second rotating shaft support42and the first rotating shaft support41, so that the rotating shaft3, the first rotating shaft support41, and the second rotating shaft support42are connected to each other. As shown inFIG. 5andFIG. 7,FIG. 5andFIG. 7show schematic diagrams of riveting connection between the second fastener422and the first body part411, where A is a riveting point.

Based on any one of the foregoing embodiments, in an embodiment of this application, the second body part421includes a first region B that overlaps the projection of the drive circuit board and a second region C that does not overlap the projection of the drive circuit board, and the first region B is fixedly connected to the housing of the display screen1by using a double-sided tape or through glue dispensing. However, this application imposes no limitation thereto. In another embodiment of this application, in a direction perpendicular to the plane on which the display screen1is located, when a distance between the first region B and the drive circuit board allows, the first region B may also be connected to the housing of the display screen1through threaded connection. To be specific, the first region B includes a first threaded hole, and the first region B is locked to the housing of the display screen1through the first threaded hole by using a bolt.

Based on the foregoing embodiment, in an embodiment of this application, as shown inFIG. 6andFIG. 7, the second region C is fixedly connected to the housing of the display screen1by using a double-sided tape or through glue dispensing. In another embodiment of this application, when space of the housing of the display screen1allows, the second region C is connected to the housing of the display screen1through threaded connection. Specifically, as shown inFIG. 4andFIG. 5, the second region C includes a second threaded hole51. Specifically, during fixing, a screw passes through the second threaded hole51of the second region C, so that the second region C of the second body part421is locked to the housing of the display screen1.

It should be noted that, in this embodiment of this application, a thickness of the first region B in the second body part421may be the same as or different from a thickness of the second region C. When the thickness of the first region B is different from the thickness of the second region C, the thickness of the first region B is less than the thickness of the second region C, to ensure that when the first region B and the drive circuit board overlap, stability of the second rotating shaft support42is increased by increasing the thickness of the second region C. This is not limited in this application, and specifically depends on a situation. A thickness of the first body part411of the first rotating shaft support41may be greater than the thickness of the first region B. Stability of the first rotating shaft support41is increased by increasing the thickness of the first body part411. The thickness of the first body part411may be the same as or different from the thickness of the second region C. This is not limited in this application, and specifically depends on a situation.

In another embodiment of this application, the first body part411is connected to the housing of the display screen1through threaded connection. Specifically, as shown inFIG. 4andFIG. 5, when the first body part411is connected to the housing of the display screen1through threaded connection, the first body part411includes a third threaded hole52, and the first body part411is locked to the housing of the display screen1through the third threaded hole52by using a bolt.

When the rotating shaft support4extends from two sides of the display screen1of the notebook computer to the middle to a region in which the drive circuit board is located, the second rotating shaft support42is disposed under the drive circuit board5, so that the drive circuit board5and the second rotating shaft support42share a partial region, to resolve a problem that a disposing location of the rotating shaft support4conflicts with a disposing location of the drive circuit board5when the rotating shaft support4extends from the two sides of the display screen1of the notebook computer to the middle to the region in which the drive circuit board5is located. Therefore, an entire size of the notebook computer is not affected because an area of the bezel region of the display screen1of the notebook computer is not increased, and costs are relatively low because the drive circuit board does not need to be modified.
