Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Referring to fig. 1 to 11, an embodiment of the present application provides an electronic device, which includes a first body and a second body connected by a rotation mechanism, wherein the first body and the second body can rotate relatively around a rotation axis 100 of the rotation mechanism, and the electronic device can be a notebook computer, a folding mobile phone, a folding tablet computer, and the like. For the convenience of understanding the scheme of the application, the notebook computer is taken as an example in the description, the part of the display screen of the notebook computer is taken as a first body in an exemplary manner, and the part of the keyboard of the notebook computer is taken as a second body in an exemplary manner. The drawings of the specification show a partial structure of the second body, and the first body and other parts of the second body are omitted, not shown, and the omitted parts can be regarded as prior art, which does not prevent understanding the scheme of the present application. The first cover 11 in fig. 1 is close to the C-face of the notebook computer, and the second cover 12 is close to the D-face of the notebook computer, that is, fig. 1 can be understood as a part inside the second body viewed after the second body is placed in a keyboard-face-down posture.

In the electronic device provided by the embodiment of the application, the second body is provided with the ventilation opening 5, the electronic device comprises the movable baffle 6 in transmission connection with the rotating shaft 100, when the first body rotates relative to the second body, the rotating shaft 100 can drive the movable baffle 6 to realize the switching between the first position and the second position, wherein the ventilation opening 5 is closed when the movable baffle 6 is positioned at the first position, and the ventilation opening 5 is opened when the movable baffle 6 is positioned at the second position. Closing the vent 5 means that the flapper 6 completely obstructs the vent 5, and opening the vent 5 means that at least a portion of the vent 5 is not obstructed by the flapper 6, i.e., the vent 5 may be completely open or partially open when the flapper 6 is in the second position. In particular, the vent 5 may be a vent located near the rotation mechanism, which facilitates the provision of a transmission mechanism between the spindle 100 and the flapper 6. The vent 5 may be a vent provided on the surface of the second body for communicating the inside and the outside of the second body, or may be a vent provided on a certain part inside the second body.

The relative position relationship between the first body and the second body changes when the first body rotates relative to the second body, and meanwhile, the movable baffle 6 is driven by the rotating shaft 100 to change in position, specifically, the relative position relationship between the first body and the second body can be matched with the first position and the second position of the movable baffle 6 according to needs, for example, after people use a notebook computer, the first body and the second body can be combined together, the host computer is not operated at this time, and the heat dissipation requirement of the equipment is reduced, so that the state when the first body and the second body are combined together in the embodiment is matched with the first position of the movable baffle 6, namely, after the notebook computer is closed, the movable baffle 6 is in the first position, and the vent 5 is not opened. When a user opens the notebook computer, the first body and the second body are usually rotated to a state with an included angle of approximately 120 degrees, so that the state when the first body and the second body are opened to an included angle of 120 degrees is matched with the second position of the movable baffle 6 in the embodiment, that is, when the notebook computer is opened to 120 degrees, the movable baffle 6 is in the second position, and the ventilation opening 5 is opened.

In a preferred embodiment, the shaft 100 is in driving engagement with the flapper 6 via a rack and pinion mechanism comprising: a gear 92 mounted to the rotating shaft 100; the rack 91 is connected to the flapper 6. As shown in fig. 2, in this embodiment, the vent 5 is disposed at the rear side of the second body, i.e. the side of the second body facing away from the user of the notebook computer, the plane of the vent 5 is substantially perpendicular to the D-plane of the notebook computer, and considering the movable space of the movable plate 6, the plate body 61 of the movable plate 6 is provided with a flexible member capable of being elastically bent and deformed, and the portion of the movable plate 6 connected to the rack 91 moves along with the rack 91 in a direction parallel to the second cover 12. To this end, the flapper 6 may include: a plate 61 for shielding the ventilation opening 5; the rod 62 is connected to the first edge of the plate 61, and the end of the rod 62 is fixedly connected to the rack 91. The second cover 12 is provided on its inner side, i.e. the side facing the first cover 11, with a first receiving element 7 and a second receiving element 8, wherein the first receiving element 7 provides a first sliding slot for sliding engagement with the rod 62 and the second receiving element 8 provides a second sliding slot for sliding engagement with the rack 91. As shown in fig. 3, since the plate body 61 is a flexible member capable of elastic bending deformation, when the rack 91 moves in a direction approaching the vent 5 with the rod body 62, a portion of the plate body 61 pushed out of the first receiving member 7 by the rod body 62 is bent and eventually shields the vent 5. Referring to fig. 5 to 10, the gear 92 in fig. 7 is turned by a certain angle (for example, 120 °) along with the rotation shaft 100 to be in the state shown in fig. 8, correspondingly, the rack 91 in fig. 5 is translated by a certain distance to be in the state shown in fig. 6, the first accommodating member 7 in fig. 5 is omitted in fig. 6, and as can be seen from fig. 5 and 6, the plate 61 is pulled back to the first accommodating member 7 when the rod 62 is translated along with the rack 91, so that the plate 61 is changed from the state of shielding the ventilation opening 5 in fig. 9 to the state of opening the ventilation opening 5 shown in fig. 10.

In order to minimize the space occupied by the rack and pinion mechanism, the pinion 92 is preferably configured as an incomplete pinion 92, and as shown in fig. 5 and 6, when the rotation angle of the rotation shaft 100 exceeds a certain value (for example, 120 °), the rack 91 is not moved with the rotation of the rotation shaft 100. In the present embodiment, the second container 8 also provides a stopper structure to limit the moving distance of the rack 91, thereby reciprocating the rack 91 within a prescribed range. As shown in fig. 2 and 3, when the flapper 6 is switched between the first position and the second position, the first edge of the plate body 61, that is, the edge connecting the rod body 62, moves in a direction perpendicular to the plane in which the vent 5 is located. In other embodiments, the ventilation opening 5 may be provided on the second cover 12, that is, the partial opening of the second cover 12 serves as the ventilation opening 5, in which case the moving direction of the rod 62 and the plane of the ventilation opening 5 satisfy a parallel relationship, and the plate 61 may not be provided as a flexible member.

When the plate 61 is configured as a flexible member capable of being elastically bent and deformed, other means may be used to switch the flapper 6 between the first position and the second position, for example, the rod 62 is connected to the shaft 100 through a gear 92 transmission mechanism, the first accommodating member 7 provides a cylindrical accommodating groove for accommodating the flapper 6, the rod 62 is coaxially disposed in the accommodating groove and is rotatably connected to the first accommodating member 7, and when the shaft 100 rotates in the forward direction, the rod 62 rotates relative to the first accommodating member 7 to wind the plate 61 onto the rod 62, thereby separating the plate 61 from the vent 5. Conversely, when the rotary shaft 100 rotates reversely, the rod 62 rotates relative to the first accommodating member 7, so that the plate 61 is unfolded and extends out of the accommodating groove, and finally reaches the ventilation opening 5 to form a shielding.

In other embodiments, the plate 61 may be a hard member, that is, the plate 61 cannot be elastically bent and deformed, and at this time, the plate 61 and the rod 62 may be rotatably connected, and a torsion spring is disposed between the plate 61 and the rod 62. For example, the plate 61 is configured as a long plate, a first long edge of the plate 61 is rotatably connected with the rod 62, a torsion spring is disposed at the connection position, when the rod 62 is located at the edge of the first accommodating member 7, the plate 61 is kept perpendicular to the second covering member 12 under the action of the torsion spring, when the rod 62 is driven by the rack 91 to move along the first chute of the first accommodating member 7, the plate 61 is rotated around the first long edge by the first accommodating member 7 against the elastic force of the torsion spring due to the force exerted by the plate 61 on the plate 61 by the first accommodating member 7, and finally the plate 61 is changed from a state perpendicular to the second covering member 12 to a state parallel to the second covering member 12, thereby opening the ventilation opening 5.

As shown in fig. 2 and 3, when the flapper 6 is switched between the first position and the second position, the first edge of the plate 61 moves along the first slide groove provided by the first housing 7. In particular, the first receiving member 7 and the second cover member 12 may be provided as an integrally formed structure. Furthermore, the second cover 12 may be an integral part of the housing of the second body. In a preferred embodiment, the electronic device includes a heat dissipation module 3 disposed on the second body, the air outlet end of the heat dissipation module 3 is opposite to the air vent 5, and the length dimension of the air vent 5 is consistent with the length dimension of the air outlet end of the heat dissipation module 3. As shown in fig. 2, the heat dissipation module 3 is disposed to face only one ventilation opening 5 over the entire length thereof, so that the maximization of the opening can be achieved as much as possible, that is, the opening ratio of the side surface portion of the first cover 11 for opening the ventilation opening 5 is maximized as much as possible, and the opening ratio is the ratio of the area of the ventilation opening 5 to the total area of the side surface portion.

As shown in fig. 4 and 11, in the present embodiment, a side portion of the first cover 11 for opening the ventilation opening 5 is provided with a flange 51, and the flange 51 is used to form a third slide groove that mates with the side edge of the flapper 6. The vent 5 generally extends in a straight line along the length direction, and as shown in fig. 11, the width of the vent 5 should be as large as possible in order to maximize the opening. When the width of the vent 5 cannot be increased any more due to factors such as safety regulations, the vent 5 may be provided to extend in a serpentine shape in the longitudinal direction, thereby increasing the aperture ratio. As shown in fig. 12, the opposite long sides of the vent 5 are alternately provided with convex shapes, so that the vent 5 is overall in a serpentine shape. Specifically, the width of the vent 5 in fig. 11 and 12 may be set to 5.3mm.

As shown in fig. 1 to 4, in the present embodiment, the rotation shaft support 2 is fixed to the first cover 11 by the second screw 42, and the rotation shaft 100 of the rotation mechanism is mounted on the rotation shaft support 2, it should be noted that, in the drawings, the rotation shaft 100 on one side of the notebook computer is shown, and the rotation shaft 100 is also disposed on the opposite side, and the rotation shafts 100 on both sides may be integrated or may be separate two parts. The first accommodating member 7 and the second accommodating member 8 can be fixed to the second cover member 12 by gluing, the heat dissipation module 3 is fixed to the first cover member 11, and the first screw 41 is screwed into the threaded hole of the first cover member 11 through the mounting hole of the second cover member 12 and the mounting hole of the rotating shaft support 2 in sequence, so that the second cover member 12 and the first cover member 11 are locked and fixed together with the rotating shaft support 2.

In the present description, the structures of the parts are described in a progressive manner, and the structure of each part is mainly described as a difference from the existing structure, and the whole and part of the structure of the electronic device can be obtained by combining the structures of the parts.
