All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The functional modules provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1 to 4, an embodiment of the present application discloses a functional module 100, and the disclosed functional module 100 includes a driving mechanism 110, a cam 120, a fan 130, and a connecting member 140.
The driving mechanism 110 is connected to the fan 130, and the driving mechanism 110 is used for driving the fan 130 to rotate. The driving mechanism 110 is connected to the connecting member 140, and the connecting member 140 is detachably connected to the cam 120. In this case, the driving mechanism 110 serves as both a power component and a base for mounting other components of the functional module 100.
In a specific operation process, when the connecting member 140 is connected to the cam 120, the driving mechanism 110 can drive the cam 120 and the fan 130 to rotate together. At this time, in the process of rotation of the cam 120, the direction of the centrifugal force applied to the cam 120 is constantly changed, so that the cam 120 can provide an acting force with a constantly changing direction for the electronic device, so that the electronic device generates vibration, and a vibration function of the electronic device is further realized. Meanwhile, since the driving mechanism 110 is further connected to the fan 130, the fan 130 can rotate while the cam 120 rotates, and the fan 130 can accelerate the air flow in the electronic device, thereby achieving a heat dissipation effect.
With the connecting member 140 and the cam 120 in the separated state, the driving mechanism 110 can drive the fan 130 to rotate. At this time, the connecting member 140 is separated from the cam 120, so the connecting member 140 cannot drive the cam 120 to rotate, and the functional module 100 only rotates the fan 130 at this time, and can only achieve the heat dissipation function.
In the embodiment disclosed in the present application, the functional module 100 can realize two functions of heat dissipation and vibration, so that it is not necessary to additionally provide a vibration module and a heat dissipation fan, and further, the installation space reserved for the electronic device is small, and the volume of the electronic device is small.
In the related art, the vibration module and the heat dissipation fan are installed in the electronic device at the same time, and the vibration module and the heat dissipation fan need to be driven by corresponding driving motors, so that the number of the driving motors is at least two. The cam 120 and the fan 130 of the functional module 100 in the present application are driven by the same driving mechanism 110, so that the power consumption of the electronic device is small.
In addition, the cam 120 and the fan 130 of the function module 100 disclosed in the present application share the same driving mechanism 110, so the function module 100 has a small volume. Meanwhile, since the functional module 100 has one less driving mechanism 110 compared to the related art, the functional module 100 has a light weight, thereby making the electronic apparatus light in weight.
In addition, when the functional module 100 vibrates, the fan 130 also rotates, and the fan 130 also slightly vibrates during the rotation process, so that the vibration of the electronic device is stronger, and the vibration effect is better.
In addition, noise may occur during the rotation of the fan 130, and when the cam 120 and the fan 130 rotate together, the noise of the fan 130 may be hidden under the sound of vibration, so that the noise of the fan 130 is weakened, and the user experience is improved.
In the above embodiment, the user can switch the operating state of the functional module 100 according to the scene, and when the user uses the electronic device to play a game, the user holds the electronic device to operate, and the vibration may cause poor operation experience of the user, so that the heat dissipation function can be separately started at this time. When the user holds the electronic equipment for operation, the user operation experience is better. When the electronic equipment is powered on, the vibration function and the heat dissipation function can be started simultaneously. This scheme has increased the use scene of functional module 100 to the performance of functional module 100 has been improved.
In another alternative, the connecting member 140 may be a telescopic mechanism, and when the electronic device is powered on, the electronic device sends a signal to extend the telescopic mechanism, so that the telescopic mechanism is engaged with the cam 120, and the vibration function and the heat dissipation function are simultaneously activated. When the electronic device only radiates heat, the retractable mechanism is not activated, and therefore the cam 120 cannot rotate, so that the functional module 100 only achieves the heat radiation function.
In another alternative embodiment, the driving mechanism 110 may include a stator seat 111 and a rotating part 112, the stator seat 111 provides a mounting base for other components of the driving mechanism 110, and in addition, the stator seat 111 may also provide a mounting base for other components of the functional module 100. The rotating part 112 is a power member, and the rotating part 112 is used for rotating the cam 120 and the fan 130 of the function module 100.
The stator holder 111 is rotatably connected to the rotating portion 112, and the rotating portion 112 is rotatable about its central axis. The cam 120 may overlap the stator holder 111, the cam 120 may be formed with a through hole 121, a portion of the rotating part 112 may be located in the through hole 121, and one end of the rotating part 112 may extend out of the through hole 121 and be connected to the fan 130. The link 140 is positioned in the through hole 121, and the link 140 is movable with respect to the rotating part 112 to switch the link 140 and the cam 120 between a connected state and a disconnected state.
In the above embodiment, when the function module 100 needs to realize the vibration function, the connecting member 140 slides to a position contacting the cam 120, so that the rotating portion 112 can drive the cam 120 to rotate. When the functional module 100 only achieves the heat dissipation function, the connecting member 140 slides to a position separated from the cam 120, i.e., does not contact the cam 120, and at this time, the connecting member 140 does not contact the cam 120, so that the connecting member 140 cannot drive the cam 120 to rotate together. The actuation of the link 140 may be by a user sliding manually or by an actuator.
In a specific operation process, the rotating portion 112 is connected to the connecting member 140, so that the rotating portion 112 drives the connecting member 140 to rotate, and the connecting member 140 rotates with the cam 120, so that the connecting member 140 can drive the cam 120 to rotate. In addition, the rotating portion 112 can also drive the fan to rotate.
In this embodiment, the functional module 100 has fewer parts, so the manufacturing process of the functional module 100 is simple and the cost is low. In addition, the components of the functional module 100 are assembled in an overlapping manner, so that the occupied space in the thickness direction, the length direction and the width direction is small, which is beneficial to the miniaturization of the functional module 100, and further, the installation space of the electronic device occupied by the functional module 100 is small, which is beneficial to the development of the light weight and the thin weight of the electronic device.
In the above embodiment, the functional module 100 further includes a circuit board 180, one end of the circuit board 180 extends into the stator seat 111 and is electrically connected to the rotating portion 112, and the other end of the circuit board 180 is electrically connected to a main board of the electronic device. The circuit board 180 is used to supply power to the rotating part 112 and also to control the rotation of the rotating part 112.
In the above embodiments, the user manually slides the connecting member 140 or the driving member alone drives the connecting member 140 to slide, which increases the difficulty of using the function module 100.
To this end, in another alternative embodiment, the function module 100 may further include an elastic member 150, one end of the elastic member 150 may be connected to the link member 140, the other end of the elastic member 150 may be connected to the rotation part 112, and the elastic member 150 may press one end of the link member 140 against the cam 120. When the elastic member 150 urges one end of the link member 140 to press the cam 120, the link member 140 is illustrated as being coupled to the cam 120.
The connection member 140 may be rotatably coupled to the rotation portion 112, and a rotation center of the connection member 140 does not coincide with a center thereof, that is, the rotation center of the connection member 140 is eccentrically disposed, and one side of the rotation center of the connection member 140 has a larger volume and the other side has a smaller volume. The rotational center of the link 140 is close to the side of the link 140 contacting the cam 120, and at this time, the side of the link 140 having a smaller volume contacts the cam 120.
In the case where the rotation speed of the driving mechanism 110 is less than or equal to the preset rotation speed, the link 140 may be in a connected state with the cam 120. At this time, since the rotation speed of the driving mechanism 110 is slow, the elastic force of the elastic member 150 is greater than the centrifugal force applied to the connecting member 140, so that the elastic member 150 can drive the connecting member 140 to press the cam 120, and the rotating portion 112 can drive the cam 120 and the fan 130 to rotate together.
In the case where the rotation speed of the driving mechanism 110 may be greater than the preset rotation speed, the link 140 is in a separated state from the cam 120. Because the rotation speed of the driving mechanism 110 is faster, the elastic force of the elastic member 150 is smaller than the centrifugal force applied to the connecting member 140, the side with the larger volume of the connecting member 140 is rotated outward by the centrifugal force, the side with the smaller volume of the connecting member 140 is rotated toward the inside by the acting force of the side with the larger volume, and the side with the smaller volume compresses the elastic member 150, so that the elastic member 150 is compressed and the connecting member 140 is separated from the cam 120. At this time, the rotating portion 112 can only drive the fan 130 to rotate, and thus can only realize the heat radiation function.
In this scheme, through the rotational speed of adjusting actuating mechanism 110 to realize the switching of heat dissipation function and vibration function, and then reduced the use degree of difficulty of functional module 100, it is more convenient to use.
Alternatively, the circuit board 180 can control the rotation speed of the rotating part 112 to select the operation mode of the functional module 100.
In the above embodiment, the sidewall of the through hole 121 should have a certain safety distance from the sidewall of the connecting member 140, so that the connecting member 140 does not interfere with the sidewall of the through hole 121 when the connecting member 140 performs a centrifugal motion, thereby ensuring the safety of the functional module 100.
The present application discloses a specific structure of the connecting member 140, but the connecting member 140 may have other structures, and is not limited herein. Specifically, the connecting member 140 may include a sector plate section 141 and a friction plate section 142, the friction plate section 142 may be located at one end of the sector plate section 141 and connected to the other end of the sector plate section 141, the rotation center of the connecting member 140 may be located at one end of the sector plate section 141 and close to the friction plate section 142, the arc-shaped surface of the sector plate section 141 faces the side wall of the through hole 121, and the elastic member 150 is connected to one side of the friction plate section 142 facing away from the side wall of the through hole 121.
With the link 140 and the cam 120 in the connected state, the friction plate segment 142 is in contact with the cam 120; in the state where the link 140 is separated from the cam 120, the friction plate segment 142 is separated from the cam 120.
In this scheme, the arcwall face of fan-shaped plate section 141 is towards the lateral wall of through-hole 121, and the arcwall face is comparatively smooth this moment, even the arcwall face of fan-shaped plate section 141 and the lateral wall contact of through-hole 121, its frictional force is less, and fan-shaped plate section 141 also is difficult for driving cam 120 and rotates, has consequently further guaranteed that function module 100 carries out radiating reliability alone.
In addition, the structure of the connection member 140 is simple, thereby making the manufacture of the function module 100 simpler and more convenient.
Alternatively, the connecting member 140 may be manufactured by a molding method of integral casting, a stamping method, or a laser cutting method.
In another alternative embodiment, the number of the connection members 140 may be at least two, and the number of the elastic members 150 may be at least two. The at least two elastic members 150 and the at least two connecting members 140 may be disposed in a one-to-one correspondence, and the at least two connecting members 140 may be disposed around the rotation axis of the rotating part 112 and may be centrosymmetric around the rotation axis of the rotating part 112. At this time, since the circumferential force of the cam 120 is balanced when the cam 120 rotates, the cam 120 is less likely to be deflected to one side.
In another alternative embodiment, the rotating portion 112 may be extended with a first extending protrusion 1123a, the connecting member 140 may be extended with a second extending protrusion, and the elastic member 150 may be sleeved on the first extending protrusion 1123a and the second extending protrusion. The first extending protrusion 1123a and the second extending protrusion may be in limit-fitted in a radial direction of the rotating portion 112 in a state where the connecting member 140 is separated from the cam 120.
In this embodiment, the first extending protrusion 1123a and the second extending protrusion may be in limit fit along the radial direction of the rotating portion 112, and the first extending protrusion 1123a and the second extending protrusion may limit the connecting member 140 to prevent the connecting member 140 from over-rotating, so as to ensure that the connecting member 140 is not easily contacted with the sidewall of the through hole 121, thereby ensuring the safety and reliability of the functional module 100.
In another alternative embodiment, the rotating portion 112 may include a rotor 1121, a rotating disc 1122 and a driving shaft 1123 stacked in sequence, the stator seat 111 may be provided with a groove 111a, the rotor 1121 and the rotating disc 1122 may be located in the groove 111a, the connecting member 140 and the driving shaft 1123 may be located on the same side of the rotating disc 1122 and rotatably connected to the rotating disc 1122, and at this time, the rotor 1121 may drive the rotating disc 1122 and the driving shaft 1123 to rotate. The fan 130 may be connected to the drive shaft 1123.
In this case, the connection member 140 is rotatably connected to the rotary plate 1122, and the fan 130 is connected to the driving shaft 1123, so that the connection member 140 and the fan 130 do not easily interfere with each other.
In addition, the rotor 1121 and the rotary disk 1122 can be located in the groove 111a of the stator holder 111, so that the stacking height of the rotor 1121, the rotary disk 1122 and the stator holder 111 is small, so that the volume of the functional module 100 is small, and the volume of the electronic device is small.
In the above embodiment, the rotor 1121 may be wound with a coil winding, the stator base 111 may be provided with a magnet set, the coil winding is energized, and the magnet set and the energized coil winding on the stator base 111 drive the rotor 1121 to rotate through electromagnetic action. The rotation of the rotor 1121 is common knowledge and will not be described in detail herein.
Alternatively, the first extending protrusion 1123a may be provided on the sidewall of the driving shaft 1123.
In another alternative embodiment, the rotary plate 1122 may be provided with a rotation shaft 1122a, and the rotation shaft 1122a may be spaced apart from the drive shaft 1123. The hinge 1122a may be disposed near an edge of the dial 1122. The connecting member 140 may be formed with a connecting hole 1411, the rotating shaft 1122a may be located in the connecting hole 1411, and the rotating shaft 1122a may be rotatably engaged with the connecting hole 1411 around a central axis of the connecting hole 1411. In this scheme, the rotation fitting between the rotation disc 1122 and the connection member 140 is realized through the rotation shaft 1122a and the connection hole 1411, so that the structure of the functional module 100 is simple and the processing difficulty is small.
In addition, the rotating shaft 1122a can be close to the edge of the rotating disc 1122, and the distance from the rotating center of the connecting piece 140 to the rotating center of the rotating disc 1122 is long, so that the centrifugal force applied to the connecting piece 140 is large, the preset rotating speed can be low, the driving mechanism 110 with the low rotating speed can be selected for the functional module 100, the manufacturing cost of the functional module 100 can be reduced, and the energy consumption of the electronic device can be reduced.
In the above embodiment, the cam 120 is in contact with the connecting member 140, and the cam 120 and the connecting member 140 are prone to slipping, so in another alternative embodiment, the function module 100 disclosed in this application may further include a friction plate 160, the friction plate 160 may be disposed on the connecting member 140, and the connecting member 140 may be in contact with the cam 120 through the friction plate 160. In this embodiment, the friction plate 160 can increase the friction between the connecting member 140 and the cam 120, and further can prevent the cam 120 and the connecting member 140 from slipping.
In another alternative embodiment, the cam 120 may be a fan-shaped structural member, an arc-shaped surface of the fan-shaped structural member may be provided with a notch, and a weight block 170 may be disposed in the notch. This increases the weight of one side of the cam 120, so that the vibration sensation is more obvious when the cam 120 rotates, and the strength of vibration is enhanced.
In the above embodiment, the driving mechanism 110 may be directly connected to the fan 130, and the installation position of the fan 130 is fixed, so the flexibility of installing the fan 130 is poor. To this end, in another alternative embodiment, the functional module 100 disclosed in the present application may further include a transmission mechanism, and the driving mechanism 110 may be connected with the fan 130 through the transmission mechanism. The scheme enables the installation position of the fan 130 to be flexible, and further improves the unlimited installation position of the functional module 100.
