The specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the application.
Generally, a fan structure is disposed in a notebook computer to dissipate heat of the notebook computer through the fan structure, where the position of the fan structure in the notebook computer can refer to fig. 1, that is, the fan is located between a keyboard assembly of the notebook computer and a bottom case of the notebook computer, and two fan structures are disposed in the notebook computer in fig. 1. In the concrete implementation, the user is when knocking notebook computer's keyboard, and keyboard subassembly atress produces the displacement to fan structure for the clearance between fan structure and the keyboard subassembly diminishes, leads to fan structure to the drain pan removal of notebook computer when user's the dynamics of knocking is great even, and at this moment, the flabellum of fan structure just can produce the friction with the lower cover plate of fan, not only sends out the noise, still can lead to notebook computer's the test failure of dispatching from the factory. The heat dissipation efficiency is reduced no matter the volume of the fan blades is reduced or the fan structure is integrally moved towards the bottom shell.
The embodiment of the application provides a fan structure 1, and this fan structure 1 not only can solve keyboard subassembly atress effectively and make the flabellum of fan subassembly 11 and the lower apron of fan subassembly 11 produce the problem of friction, can also ensure that fan structure 1's radiating efficiency is not influenced. Next, the fan structure 1 provided in the present application will be described in detail.
Referring to a schematic structural diagram of the fan structure 1 shown in fig. 2, the fan structure 1 of the embodiment of the present application includes a fan assembly 11, a pressure detection assembly 12, and a driving assembly 13. Fig. 3 shows a schematic structural diagram of a side surface of the fan structure 1 according to the embodiment of the present application, and fig. 3 does not show the driving component 13, specifically shows that the pressure detecting component 12 is located between the fan component 11 and the keyboard component.
As one example, the fan assembly 11 in the embodiment of the present application includes an upper cover plate, a lower cover plate, and fan blades. Specifically, the keyboard assembly is located on one side of the upper cover plate away from the lower cover plate, and the pressure detection assembly 12 is attached to one side of the upper cover plate away from the lower cover plate, so as to ensure that the pressure detection assembly 12 can accurately determine the pressure borne by the fan assembly 11, wherein the first area of the pressure detection assembly 12 on the horizontal plane is the same as the second area of the fan assembly 11 on the horizontal plane, and of course, the first area of the pressure detection assembly 12 on the horizontal plane can be set to be larger than the second area of the fan assembly 11 on the horizontal plane, so as to ensure that the pressure on the keyboard assembly can be accurately determined.
Furthermore, the fan blades are positioned between the upper cover plate and the lower cover plate, the fan blades and the upper cover plate are relatively fixed, namely, the distance between the fan blades and the upper cover plate is fixed, the upper cover plate and the lower cover plate are movably connected through the connecting assembly, so that the distance between the upper cover plate and the lower cover plate can be adjusted at any time according to actual requirements, and the distance between the lower cover plate and the fan blades is kept to be N under the condition that the keyboard assembly does not bear pressure; under the condition that the keyboard assembly bears pressure, the distance between the lower cover plate and the fan blades is larger than N. Therefore, the problem of low heat dissipation efficiency caused by friction between the fan blades and the lower cover plate can be avoided on the basis of ensuring that the notebook computer is light and thin.
Optionally, the connecting assembly for movably connecting the upper cover plate and the lower cover plate includes a first connecting member and a second connecting member, where the first connecting member is located on the upper cover plate, the second connecting member is located on the lower cover plate, and after the fan assembly 11 is assembled, the position of the first connecting member and the position of the second connecting member correspond to each other to cooperatively realize the connection of the upper cover plate and the lower cover plate, thereby forming the fan assembly 11.
In particular implementations, the pressure sensing assembly 12 is used to determine the pressure experienced by the fan assembly 11. The pressure detecting component 12 may include a pressure sensor attached to one side of the fan component 11 close to the keyboard component, and when the keyboard component is forced to displace towards the fan component 11, that is, the keyboard component applies pressure to the pressure detecting component 12, the pressure sensor of the pressure detecting component 12 may detect the currently borne pressure; the pressure detecting component 12 may further include a controller, which is connected to a processor or a controller of the electronic device to which the fan structure 1 belongs, and the controller may be configured to monitor an operating state of the electronic device in real time, for example, monitor whether the electronic device runs an application program, further determine whether to use a keyboard component when determining that the electronic device runs the application program, and when determining that to use the keyboard component when determining that the application program runs, may determine that the pressure borne by the fan component 11 is a preset pressure, and the like, which is not specifically limited in this embodiment of the present application.
Further, the driving assembly 13 is electrically connected to the pressure detecting assembly 12, and the driving assembly 13 is connected to the fan assembly 11. In a specific implementation, the pressure detection component 12 transmits the pressure borne by the fan component 11 to the driving component 13 after determining the pressure borne by the fan component 11, and the driving component 13 drives the fan component 11 to deform based on the pressure after receiving the pressure determined by the pressure detection component 12, so that no friction is generated between the fan blades of the fan component 11 and the lower cover plate of the fan component 11, thereby ensuring that the heat dissipation performance of the fan structure 1 is not affected. Wherein the drive assembly 13 comprises a motor to provide a driving force for the fan assembly 11.
In the embodiment of the present application, after determining the pressure borne by the fan assembly 11, the pressure detection assembly 12 further determines whether the pressure meets a driving condition, where the driving condition is that the pressure is greater than or equal to a preset pressure, that is, when the pressure borne by the fan assembly 11 is the preset pressure, the fan assembly 11 may deform, that is, the distance between the fan blade and the lower cover plate is reduced, or even friction is generated, and in an application scenario defined in the embodiment of the present application, the preset pressure may be set to be 5 kg.
In consideration of different force for knocking the keyboard by different users, the preset pressure can be set to be adjustable in the embodiment of the application, for example, when the force for knocking the keyboard by the user is large, the preset pressure can be set to be large by the user so as to avoid the problem that resources are wasted when the driving component 13 is started due to mistaken touch of the keyboard component; under the condition that the force of knocking the keyboard by the user is small, the user can set the preset pressure to be small so as to avoid the condition that the pressure detection assembly 12 cannot trigger the driving assembly 13, ensure that the pressure detection assembly 12 accurately triggers the driving assembly 13 without wasting resources, and be suitable for various scenes and requirements and have strong flexibility.
Under the condition that the pressure detection component 12 determines that the pressure meets the driving condition, that is, the pressure borne by the fan component 11 is greater than the preset pressure, a driving signal is generated, wherein the driving signal indicates that the driving component 13 drives the lower cover plate to move towards the side away from the upper cover plate; at the same time, the drive signal is sent to the drive assembly 13.
After receiving the driving signal, the driving component 13 responds to the driving signal, i.e., drives the lower cover plate to move to the side away from the upper cover plate, so that the distance between the lower cover plate and the fan blades is greater than N, and even if the fan blades move toward the lower cover plate, the fan blades do not rub against the lower cover plate to reduce the heat dissipation efficiency, thereby ensuring that the heat dissipation efficiency of the fan structure 1 is not affected. As an example, fig. 4 shows a schematic structural diagram of the fan structure 1 when the distance between the lower cover plate and the fan blade is N, and fig. 5 shows a schematic structural diagram of the fan structure 1 when the distance between the lower cover plate and the fan blade is greater than N.
In another embodiment, the driving component 13 may also poll the pressure detecting component 12 in real time or periodically to obtain the pressure determined by the pressure detecting component 12, determine whether the pressure satisfies the driving condition by the driving component 13, and drive the lower cover plate to move away from the side of the upper cover plate so that the distance between the lower cover plate and the fan blade is greater than N if the pressure satisfies the driving condition.
Further, in the case that the distance between the lower cover plate and the fan blade is greater than N, the pressure detection assembly 12 still monitors and determines the pressure borne by the fan assembly 11 in real time, and the pressure detection assembly 12 further determines whether the pressure borne by the fan assembly 11 meets the recovery condition. Wherein the recovery condition is that the pressure is less than a preset pressure.
In the case where it is determined that the pressure satisfies the recovery condition, generating a recovery signal for instructing the driving assembly 13 to drive the lower cover plate to move to a side close to the upper cover plate; at the same time, the drive signal is sent to the drive assembly 13.
After receiving the recovery information, the driving assembly 13 responds to the recovery signal, that is, drives the lower cover plate to move to a side close to the upper cover plate, so that the distance between the lower cover plate and the fan blades is N, that is, after determining that the pressure borne by the fan assembly 11 is less than the preset pressure, the distance between the lower cover plate and the fan blades is recovered to a state that the pressure detection side assembly, or even the keyboard assembly, does not bear the pressure.
In another embodiment, considering that there is a user who has a slow keyboard component knocking speed, at this time, the driving component 13 needs to repeatedly respond to the driving signal and the recovery signal to ensure that the heat dissipation efficiency of the fan component 11 is not affected, but such repeated response to the driving signal and the recovery signal causes consumption of system resources and loss of the connection component, in order to solve this problem, in this embodiment of the present application, a recovery condition may be further set that the pressure is less than the preset pressure for a preset duration, for example, the preset duration is 0.5s, that is, it is determined whether the pressure borne by the fan component 11 is less than the preset pressure, if the pressure borne by the fan component 11 is less than the preset pressure, it is further determined that the pressure is less than the duration of the preset pressure, and if the duration reaches the preset duration, that is, that the duration is greater than or equal to 0.5s, it is determined that the pressure satisfies the recovery condition, a restoring signal is then generated and sent to the drive assembly 13 such that the drive assembly 13, in response to the restoring signal, drives the lower cover plate to move toward the side adjacent to the upper cover plate such that the distance between the lower cover plate and the fan blades is N. Therefore, the system resource consumption and the loss of the connecting component caused by repeated response of the driving component 13 to the driving signal and the recovery signal can be avoided, the system resource consumption is reduced to a certain extent, and the service life of the connecting component is prolonged.
The embodiment of the application determines the pressure born by the fan assembly in real time through the pressure detection assembly, and drives the fan assembly to deform in time through the driving assembly based on the pressure so as to ensure that the heat dissipation efficiency of the fan structure is not influenced by the pressure, thereby effectively solving the problem that the heat dissipation efficiency is reduced due to the friction between the fan blades of the fan assembly and the lower cover plate of the fan assembly caused by the stress of the keyboard assembly, and achieving the purpose of ensuring the heat dissipation efficiency of the fan structure on the basis of not changing the volume of the fan blades.
Based on the same inventive concept, a second aspect of the present application further provides an electronic device, including a keyboard assembly, a bottom case, and the fan structure according to any one of the first aspects, the fan structure being located between the keyboard assembly and the bottom case, the fan structure being used for determining a pressure on the keyboard assembly and dissipating heat for the electronic device.
Specifically, under the condition that the user knocked the keyboard, the pressure that the fan structure bore was confirmed in real time to the pressure detection subassembly that the fan structure includes, and confirm whether the pressure that this fan structure bore satisfies the drive condition, under the condition that this pressure satisfies the drive condition, the lower apron that the drive fan structure includes moves to the one side of keeping away from the upper cover plate that the fan structure includes, so that the distance between the lower apron that the fan structure includes and the flabellum that the fan structure includes is greater than N, and then avoid flabellum and lower apron to produce the problem that the friction causes the radiating efficiency to reduce, the purpose that the radiating efficiency of fan structure is not influenced has been reached.
And under the condition that the distance between the lower cover plate and the fan blades is larger than N, the pressure detection assembly included in the fan structure still monitors and determines the pressure borne by the fan structure in real time, and further determines whether the pressure borne by the fan structure meets a recovery condition, and under the condition that the pressure meets the recovery condition, the lower cover plate is driven to move towards one side close to the upper cover plate, so that the distance between the lower cover plate included in the fan structure and the fan blades included in the fan structure is N.
The embodiment of the application determines the pressure born by the fan assembly included by the fan structure in real time through the pressure detection assembly included by the fan structure, and the driving assembly included by the fan structure is timely deformed based on the pressure to drive the fan assembly, namely, the distance between the lower cover plate and the fan blades is larger than N, so that the heat dissipation efficiency of the fan structure is not influenced by the pressure, the problem of reduction of the heat dissipation efficiency caused by friction between the fan blades of the fan assembly and the lower cover plate of the fan assembly due to the stress of the keyboard assembly is effectively solved, and the purpose of ensuring the heat dissipation efficiency of the fan structure on the basis of not changing the volume of the fan blades is achieved.
