Detailed Description

The present invention will be described in detail below with reference to the drawings and detailed description to enable those skilled in the art to better understand the technical scheme of the present invention.

As shown in fig. 1 to 10, an embodiment of the present invention discloses an electronic apparatus including a first body 10, a second body 20, a rotation shaft 30, and an actuator. The first body 10 and the second body 20 are rotatably connected through the rotation shaft 30 such that the second body 20 has a closed state (an angle between the first body 10 and the second body 20 is 0 ° when the second body 20 is in the closed state, as shown in fig. 1) and an open state (an angle between the first body 10 and the second body 20 is any angle between 0 and a maximum open angle when the second body 20 is in the open state, as shown in fig. 4 and 7) with respect to the first body 10 by rotation, the first body 10 specifically includes the upper case 13, the lower case 12, and hardware provided between the upper case 13 and the lower case 12, and the lower case 12 can be moved in directions approaching and separating from the upper case 13, thereby enabling the lower case 12 to be brought into a fastened state with the upper case 13 and to be brought into an open state with the upper case 13. The space defined by the upper case 13 and the lower case 12 can be effectively used as a heat dissipation space of the hardware, and the heat dissipation space is increased to accelerate heat dissipation of the hardware in operation when the lower case 12 is switched from the fastened state to the opened state. The actuating element is linked with the formation of the rotating shaft 30 in a selection way, when the rotating shaft 30 is linked with the actuating element, the actuating element is driven to rotate, the actuating element pushes the lower shell 12 towards the direction away from the upper shell 13, and the time of the linkage of the rotating shaft 30 and the actuating element is set as follows: after the opening angle of the second body 20 exceeds a preset angle, the rotating shaft 30 and the actuating member start to be linked, and when the second body 20 is opened from the preset angle to the maximum angle, the rotating shaft 30 drives the actuating member to push the actuating member against the lower shell 12 in a direction away from the upper shell 13, so that the lower shell 12 is finally switched to the opened state.

As can be seen from the above description, the present invention relates the open/close state of the second body 20 to the open/close state of the lower case 12, and when the second body 20 is opened to enable the electronic device to be in the operation state, the lower case 12 is also switched to the open state, so that the heat dissipation space between the upper case 13 and the lower case 12 is increased, the heat dissipation speed of the operating hardware is increased, and when the second body 20 is closed, the thickness of the first body 10 can be reduced by resetting the lower case 12 to the fastening state.

The electronic device of the invention associates the opening and closing state of the electronic device with the thickness (or the heat dissipation space) of the first body 10, so that when the electronic device operates, as shown in fig. 7, the first body 10 has a larger heat dissipation space, and when the electronic device is idle, as shown in fig. 1, an excessive heat dissipation space is not required to be reserved in the first body 10, so that the first body 10 (when the lower shell 12 is in a buckling state) of the electronic device can be set thinner.

It should be noted that: the predetermined angle is a node angle of the rotation shaft 30 associated with the actuator. The preset angle is selected and set to meet the habit requirements of the user for operating the electronic equipment. For example, the electronic device is a notebook computer, the second body 20 is a display end of the notebook computer, the first body 10 is a system end of the notebook computer, as shown in fig. 4, for a user using the notebook computer, the user is used to operate the electronic device at least when the display end is opened by 60 °, that is, if the display end is at an opening angle of 60 ° or more, the notebook computer is usually marked to be in an operating state, at this time, the lower case 12 should be started to be opened, and accordingly, the preset angle should be set to be 60 °.

It should be noted that: when the action relation between the opening process of the lower case 12 and the opening process of the second body 20 is configured, the opening angle of the second body 20 should be switched to the complete opening state as quickly as possible when the opening angle of the second body 20 just exceeds the preset angle, and the lower case 12 should be prevented from being switched to the complete opening state when the opening angle of the second body 20 is far greater than the preset angle and even reaches the maximum opening angle, so that the improvement of the opening sensitivity of the lower case 12 is facilitated, and the opening state of the lower case 12 is prevented from being limited by the opening angle of the second body 20.

There are various ways in which the lower case 12 is close to or far from the upper case 13, for example, the whole lower case 12 may be far from or close to the upper case 13 to be opened or closed, in a preferred embodiment of the present invention, as shown in fig. 4, 5, 7, 8, specifically, the lower case 12 is movably connected with the upper case 13 at a side far from the rotation shaft 30, for example, the lower case 12 is connected with the upper case 13 by a flexible plate at a side far from the rotation shaft 30, or the lower case 12 is pivotally connected with the upper case 13 by a pin at a side far from the rotation shaft 30, an actuator is mounted on the rotation shaft 30 and located between the upper case 13 and the lower case 12 at a side near the rotation shaft 30, so that, as shown in fig. 1, a side of the lower case 12 near the rotation shaft 30 is moved toward the upper case 13 to be closed as shown in fig. 7, and the side is moved toward a direction far from the upper case 13 by the actuator to be opened. As shown in fig. 7, when the lower case 12 is in the opened state, the heat dissipation space (or the thickness of the first body 10) in the first body 10 at the side close to the rotation shaft 30 is larger than the heat dissipation space (or the thickness of the first body 10) in the first body 10 at the side far from the rotation shaft 30, and the characteristics of the heat dissipation space exactly conform to the characteristics of the hardware arrangement (the hardware having a larger heat generation amount in the first body 10 is generally arranged at the side close to the rotation shaft 30), so that the heat dissipation speed of the hardware can be increased. In order to limit the movement of the lower shell 12 towards the direction close to or far from the rotating shaft 30, a limit groove 11 is formed in the side edge of the lower shell 12 from top to bottom, a limit column 21 is arranged at a position corresponding to the upper shell 13, and in the opening process of the lower shell 12, the limit column 21 is always positioned in the limit groove 11, so that the lower shell 12 is limited to move towards the direction close to or far from the rotating shaft 30 by the cooperation of the limit groove 11 and the limit column 21, and the lower shell 12 and the upper shell 13 can be strictly buckled.

The movement mode and structure of the actuating member may be various, for example, the actuating member may be a telescopic rod capable of moving vertically, when the telescopic rod is extended, the lower shell 12 is pushed to be far away from the upper shell 13 so as to be opened relative to the lower shell 12, when the telescopic rod is retracted, the lower shell 12 is buckled with the upper shell 13 by moving towards the upper shell 13, and the rotating shaft 30 and the telescopic rod can be linked through a wedge-shaped strip. In a preferred embodiment of the present invention, as shown in fig. 2, 5 and 8, a cam 40 is selected as the actuator, and in particular, the cam 40 has a cam surface 41 on the wheel surface, and the cam 40 rotates to bring the cam surface 41 into contact with the lower case 12, so that the cam surface 41 pushes down against the lower case 12 to open the lower case 12. The timing of bringing the cam 40 into association with the rotation shaft 30 so that the cam surface 41 contacts the lower case 12 should be selected as follows: during the opening of the second body 20 from the preset angle to the maximum angle, the rotation shaft 30 drives the cam 40 to rotate so that the cam surface 41 comes into contact with the lower case 12. In order to allow the lower case 12 to be rapidly switched to the fully opened state immediately after the second body 20 exceeds the preset angle to improve the sensitivity of the lower case 12 to be opened, the rate of change of the curvature of the cam surface 41, that is, the change of the curvature of the cam surface 41 in the circumferential direction can be increased.

In order to enable the lower case 12 to automatically move toward the upper case 13 to be engaged with the upper case 13 when the second body 20 is rotated to the closed state, the electronic device further includes a reset member for driving the lower case 12 to be automatically engaged with the upper case 13.

The types and the arrangement positions of the resetting pieces can be various, for example, the resetting pieces are elastic bending plates which are arranged on the side far away from the rotating shaft 30 and are used for connecting the upper shell 13 and the lower shell 12, and the elastic bending plates enable the upper shell 13 and the lower shell 12 to be movably connected on the side far away from the rotating shaft 30; on the other hand, elastic potential energy is accumulated when the side of the lower case 12 close to the rotation shaft 30 is far away from the upper case 13, so that when the second body 20 rotates to the closed state to release the pushing of the lower case 12 by the actuator, the elastic bending plate releases the elastic potential energy to reset the lower case 12 and engage with the upper case 13. For another example, the reset member is a reset spring provided between the upper case 13 and the lower case 12, and the reset spring accumulates elastic potential energy during the opening of the lower case 12, and releases the elastic potential energy to engage the lower case 12 with the upper case 13 when the second body 20 rotates to the closed state.

In a preferred embodiment of the present invention, as shown in fig. 5, the restoring member includes a first magnet 51 provided on the upper surface of the lower case 12 and a second magnet 52 rotated with the cam 40, and the magnetic pole correspondence relationship between the first magnet 51 and the second magnet 52 is set to: when the second body 20 rotates between its closed state and a preset angle, the first magnet 51 and the second magnet 52 generate a magnetic attraction force. Thus, when the second body 20 is switched to the closed state, the first magnet 51 and the second magnet 52 are finally switched to the opposite magnetic poles, and the magnetic attraction between the first magnet 51 and the second magnet 52 causes the lower case 12 to move toward the upper case 13 and finally maintains the lower case 12 in the engaged state with the upper case 13.

As can be seen from the above, when the rotating shaft 30 rotates between the closed state and the preset angle along with the second body 20, there is no linkage between the rotating shaft 30 and the actuating member, that is, when the second body 20 rotates between the closed state and the preset angle, the rotating shaft 30 is in an idle state, and when the second body 20 rotates between the preset angle and the maximum opening angle, the rotating shaft 30 is linked with the actuating member. In order to achieve the above-mentioned transmission relationship between the rotation shaft 30 and the actuating member, in a preferred embodiment of the present invention, as shown in fig. 3, 6 and 9, the rotation shaft 30 is provided with a segment of sector gear 70 in its circumferential direction, a transmission gear 80 is provided between the rotation shaft 30 and the cam 40, the sector gear 70 is in a non-engaged state with the transmission gear 80 when the second body 20 rotates between its closed state and a preset angle, and the sector gear 70 is engaged with the transmission gear 80 to drive the cam 40 to rotate when the second body 20 rotates between its maximum open angle and a preset angle. In the present embodiment, the advantage of providing the sector teeth 70 on the rotation shaft 30 is that: on the one hand, when the opening angle of the second body 20 is greater than the preset angle, the rotation shaft 30 and the cam 40 can be linked; on the other hand, the lower case 12 is prevented from being completely closed due to interference of the rotary shaft 30 with the lower case 12 by providing full teeth in the circumferential direction thereof.

The cam 40 may be mounted on the rotating shaft 30 in various manners, in a preferred embodiment of the present invention, as shown in fig. 10, the rotating shaft 30 is further sleeved with a retainer 60, specifically, the retainer 60 is a U-shaped frame, two ends of the U-shaped frame are sleeved on the rotating shaft 30, two battens of the U-shaped frame are respectively provided with the cam 40, correspondingly, the rotating shaft 30 is provided with two sets of sector teeth 70 respectively corresponding to the cam 40, and a transmission gear 80 is disposed between each cam 40 and the sector tooth 70 corresponding to the cam 40. In this way, the lower case 12 is pushed away from the upper case 13 by the two cams 40 together.

In various configurations of the first magnet 51 and the second magnet 52, if the cams 40 are mounted in the above-described manner, as shown in fig. 2, 8 and 10, the spindle 90 is provided between the two cams 40, the second magnet 52 is provided in a sleeve shape, the second magnet 52 may be called a sleeve, the sleeve is provided on the spindle 90, the first magnet 51 is provided in a plate shape, the plate-shaped magnet is attached to a position where the upper plate surface of the lower case 12 is opposite to the sleeve, a section on the outer circumferential surface of the sleeve is magnetized to form the magnet section 521, the magnetic pole of the magnet section 521 on the outer circumferential surface is different from the magnetic pole of the upper plate surface of the first magnet 51, and when the second body 20 rotates between the closed state and the preset angle, the magnet section 521 on the sleeve always has a portion opposite to the first magnet 51, so that when the second body 20 is in the closed state, the magnetic attraction between the first magnet 51 and the second magnet 52 makes the lower case 12 in the closed state.

In a preferred embodiment of the present invention, as shown in fig. 10, the rotating shaft 30 is sleeved with two bearing frames, namely, a first bearing frame 101 and a second bearing frame 102, the first body 10 is fixed on the first bearing frame 101, the second body 20 is fixed on the second bearing frame 102, and the two strips of the retainer 60 are formed with mounting portions 61, and the mounting portions 61 are used for fixedly connecting with the inside of the second body 20.
