Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The functional module provided in the embodiment of the present application is described in detail below by means of specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Referring to fig. 1 to 4, a functional module 100 is disclosed in the embodiment of the present application, 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. At this time, the driving mechanism 110 serves as a power component as well as a mounting base for other constituent components of the functional module 100.
During a specific operation, when the connecting member 140 is connected to the cam 120, the driving mechanism 110 may drive the cam 120 and the fan 130 to rotate together. At this time, the direction of the centrifugal force received by the cam 120 is continuously changed during the rotation process, so that the cam 120 can provide an acting force with continuously changing direction for the electronic device, thereby enabling the electronic device to generate vibration feeling and further realizing the vibration function of the electronic device. Meanwhile, since the driving mechanism 110 is further connected with 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 equipment, so that the heat dissipation effect can be realized.
In the case that the connecting member 140 is separated from the cam 120, the driving mechanism 110 may drive the fan 130 to rotate. At this time, the connecting member 140 is separated from the cam 120, so that the connecting member 140 cannot drive the cam 120 to rotate, and therefore, only the fan 130 of the functional module 100 rotates, and only the heat dissipation function can be achieved.
In the embodiment disclosed in the application, the function module 100 can realize two functions of heat dissipation and vibration, so that the vibration module and the heat dissipation fan do not need to be additionally arranged, and further the reserved installation space of the electronic equipment is smaller, and the volume of the electronic equipment is smaller.
In the related art, a vibration module and a cooling fan are installed in an electronic device at the same time, and the vibration module and the cooling 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 energy consumption of the electronic device is smaller.
In addition, the cam 120 and the fan 130 of the functional module 100 disclosed in the present application share the same driving mechanism 110, so the functional module 100 has a smaller volume. Meanwhile, since the functional module 100 has one driving mechanism 110 less than the related art, the functional module 100 is lighter in weight, thereby making the electronic device lighter in weight.
In addition, when the functional module 100 in the present application vibrates, the fan 130 also rotates, and the fan 130 also slightly vibrates during the rotation process, so that the vibration feeling of the electronic device is stronger, and the vibration effect is better.
In addition, the fan 130 rotates with noise, and when the cam 120 and the fan 130 rotate together, the noise of the fan 130 can be hidden under the vibration sound, so that the noise of the fan 130 is weakened, and the customer experience is improved.
In the above embodiment, the user may switch the working state of the functional module 100 according to the scene, and when the user plays a game using the electronic device, 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 may be independently started at this time. When the user holds the electronic equipment to operate, the user operation experience is good. When the electronic device is powered on, the vibration function and the heat dissipation function can be started simultaneously. This solution increases the usage scenario of the functional module 100, thereby improving the usage performance of the functional module 100.
In another alternative, the connection 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 clamped with the cam 120, and the vibration function and the heat dissipation function are started simultaneously. When the electronic device only dissipates heat, the telescopic mechanism is not started, so that the cam 120 cannot rotate, and the functional module 100 only achieves the heat dissipation function.
In another alternative embodiment, the driving mechanism 110 may include a stator base 111 and a rotating portion 112, where the stator base 111 provides a mounting base for other components of the driving mechanism 110, and the stator base 111 may also provide a mounting base for other components of the functional module 100. The rotating portion 112 is a power component, and the rotating portion 112 is used for rotating the cam 120 and the fan 130 of the functional module 100.
The stator base 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 base 111, the cam 120 may be provided with a through hole 121, a portion of the rotating part 112 may be positioned 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 the coupled state and the uncoupled state.
In the above embodiment, when the function module 100 needs to implement the vibration function, the connection 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 performs the heat dissipation function, the connecting member 140 slides to a position separated from the cam 120, that is, not in contact with the cam 120, and at this time, the connecting member 140 is not in contact with the cam 120, so that the connecting member 140 cannot drive the cam 120 to rotate together. The driving of the connection member 140 may be manually slid by a user or may be driven by a driving member.
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 may also drive the fan to rotate.
In this scheme, 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 stacked assembly mode is adopted between the components of the functional module 100, so that the space occupied in the thickness direction, the length direction and the width direction is smaller, thereby being beneficial to miniaturization of the functional module 100, further enabling the functional module 100 to occupy smaller installation space of the electronic device, and being beneficial to light and thin development 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 base 111 and is electrically connected to the rotating portion 112, and the other end of the circuit board 180 is electrically connected to the motherboard of the electronic device. The circuit board 180 is used for supplying power to the rotating part 112 and controlling the rotating part 112 to rotate.
In the above embodiments, the manual sliding of the connecting member 140 by the user or the separate driving of the connecting member 140 by the driving member can increase the difficulty in using the functional module 100.
To this end, in another alternative embodiment, the functional module 100 may further include an elastic member 150, one end of the elastic member 150 may be connected to the connection member 140, the other end of the elastic member 150 may be connected to the rotation portion 112, and the elastic member 150 may press one end of the connection member 140 against the cam 120. When the elastic member 150 urges one end of the connection member 140 to press against the cam 120, it is explained that the connection member 140 is in a connected state with the cam 120.
The connecting member 140 may be rotatably connected to the rotating portion 112, and the rotation center of the connecting member 140 is not coincident with the center thereof, that is, the rotation center of the connecting member 140 is eccentrically disposed, and one side of the rotation center of the connecting member 140 has a larger volume and the other side has a smaller volume. The rotation center of the connection member 140 is near the side of the connection member 140 contacting the cam 120, and at this time, the smaller side of the connection member 140 contacts the cam 120.
In case that the rotational speed of the driving mechanism 110 is less than or equal to the preset rotational speed, the connection member 140 may be in a connected state with the cam 120. At this time, since the rotation speed of the driving mechanism 110 is slower, 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 case that the rotational speed of the driving mechanism 110 may be greater than the preset rotational speed, the connection member 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 of the connecting member 140 with larger volume is rotated outwards by the centrifugal force, the side of the connecting member 140 with smaller volume is acted by the force with larger volume, and the side with smaller volume is rotated towards the inner side, so that the elastic member 150 is compressed, and the connecting member 140 is separated from the cam 120. At this time, the rotation part 112 can only drive the fan 130 to rotate, and thus can only realize a heat radiation function.
In this scheme, through the rotational speed of adjustment actuating mechanism 110 to realize the switching of heat dissipation function and vibration function, and then reduced the use degree of difficulty of function module 100, it is more convenient to use.
Alternatively, the circuit board 180 above can control the rotation speed of the rotation part 112, thereby selecting the operation mode of the functional module 100.
In the above embodiment, the side wall of the through hole 121 should have a certain safety distance from the side wall of the connecting piece 140, so that the connecting piece 140 and the side wall of the through hole 121 will not interfere when the connecting piece 140 performs centrifugal movement, thereby ensuring the safety performance of the functional module 100.
The present application discloses a specific structure of the connecting member 140, however, the connecting member 140 may have other structures, which are not limited herein. Specifically, the connection member 140 may include a sector plate section 141 and a friction plate section 142, the friction plate section 142 may be connected at one end of the sector plate section 141, the rotation center of the connection member 140 may be located at one end of the sector plate section 141 and close to the friction plate section 142, the arc surface of the sector plate section 141 faces the sidewall of the through hole 121, and the elastic member 150 is connected with one side of the friction plate section 142 facing away from the sidewall of the through hole 121.
With the connector 140 in a connected state with the cam 120, the friction plate segment 142 is in contact with the cam 120; with the connector 140 in a disengaged state with the cam 120, the friction plate segment 142 is disengaged from the cam 120.
In this scheme, the arc surface of the sector plate section 141 faces the side wall of the through hole 121, and at this time, the arc surface is smooth, and even if the arc surface of the sector plate section 141 contacts the side wall of the through hole 121, the friction force is small, the sector plate section 141 is not easy to drive the cam 120 to rotate, so that the reliability of the function module 100 for heat dissipation alone is further ensured.
In addition, the structure of the connection member 140 is simple, so that the manufacturing of the functional module 100 is simpler and more convenient.
Alternatively, the connecting member 140 may be manufactured by integrally casting, stamping, or laser cutting.
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 rotation portion 112 and may be centrosymmetric around the rotation axis of the rotation portion 112. At this time, since the force applied to the cam 120 in the circumferential direction is relatively uniform 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 extension protrusion 1123a, the connecting member 140 may be extended with a second extension protrusion, and the elastic member 150 may be sleeved on the first extension protrusion 1123a and the second extension protrusion. With the connecting member 140 in a separated state from the cam 120, the first extension protrusions 1123a and the second extension protrusions may be limitedly fitted in the radial direction of the rotating portion 112.
In this solution, the first extension protrusion 1123a and the second extension protrusion may be in a radial limit fit along the rotating portion 112, where the first extension protrusion 1123a and the second extension protrusion may limit the connecting member 140, so as to prevent the connecting member 140 from excessively rotating, thereby ensuring that the connecting member 140 is not easily contacted with the sidewall of the through hole 121, and further ensuring safety and reliability of the functional module 100.
In another alternative embodiment, the rotating portion 112 may include a rotor 1121, a turntable 1122, and a driving shaft 1123 stacked in sequence, the stator base 111 may be provided with a groove 111a, the rotor 1121 and the turntable 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 turntable 1122 and rotatably connected with the turntable 1122, and at this time, the rotor 1121 may rotate the turntable 1122 and the driving shaft 1123. The fan 130 may be connected to the driving shaft 1123.
In this embodiment, the connection member 140 is rotatably connected to the turntable 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 turn table 1122 may be located in the groove 111a of the stator housing 111, thus making the stacking height of the rotor 1121, the turn table 1122, and the stator housing 111 small, thus making the volume of the functional module 100 small, thus making the volume of the electronic device 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 group, the coil winding is energized, and the magnet group and the energized coil winding on the stator base 111 drive the rotor 1121 to rotate by electromagnetic action. The rotation of the rotor 1121 is common knowledge and is not described in detail herein.
Alternatively, the first extension protrusions 1123a described above may be provided on the side wall of the driving shaft 1123.
In an alternative embodiment, the rotary disk 1122 may be provided with a rotary shaft 1122a, and the rotary shaft 1122a may be spaced apart from the driving shaft 1123. The rotational shaft 1122a may be provided near an edge of the rotational disk 1122. The connection member 140 may be provided with a connection hole 1411, the rotation shaft 1122a may be positioned in the connection hole 1411, and the rotation shaft 1122a may be rotatably fitted with the connection hole 1411 around a central axis of the connection hole 1411. In this scheme, the rotary table 1122 and the connecting piece 140 are in a rotary fit through the rotary shaft 1122a and the connecting hole 1411, so that the functional module 100 has a simple structure and a small processing difficulty.
In addition, the rotating shaft 1122a may be disposed near the edge of the rotating disk 1122, and the rotation center of the connecting member 140 is far away from the rotation center of the rotating disk 1122, so that the centrifugal force received by the connecting member 140 is large, so that the preset rotation speed may be lower, and the function module 100 may select the driving mechanism 110 with a lower rotation speed, thereby reducing the manufacturing cost of the function module 100 and reducing the energy consumption of the electronic device.
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 functional module 100 disclosed herein may further include a friction plate 160, where 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, so as to avoid slipping between the cam 120 and the connecting member 140.
In another alternative embodiment, the cam 120 may be a fan-shaped structure, and the arc surface of the fan-shaped structure may be provided with a gap, and the balancing weight 170 may be disposed in the gap. This solution increases the weight of one side of the cam 120, so that the vibration feeling is more remarkable when the cam 120 rotates, and the intensity of the vibration is enhanced.
In the above embodiment, the driving mechanism 110 may be directly connected to the fan 130, where the installation position of the fan 130 is relatively fixed, so that the flexibility of installing the fan 130 is relatively poor. To this end, in an alternative embodiment, the functional module 100 disclosed herein may further include a transmission mechanism, and the driving mechanism 110 may be connected to the fan 130 through the transmission mechanism. This solution makes the installation position of the fan 130 more flexible, and thus improves the installation position of the functional module 100 without limitation.
Alternatively, the transmission mechanism may be a gear mechanism, a combination mechanism of a gear and a rack, or a worm gear mechanism, which is not limited herein.
Based on the functional module 100 of any one of the above embodiments of the present invention, the embodiment of the present invention further discloses an electronic device, where the disclosed electronic device includes the functional module 100 of any one of the above embodiments. Referring to fig. 5 and fig. 6, the electronic device disclosed in the present application further includes a first housing 200, the first housing 200 may be provided with a first inner cavity 210, and the functional module 100 may be disposed in the first inner cavity 210. At this time, the functional module 100 can exhaust the hot gas in the first cavity 210 to the outside of the first housing 200, and can also drive the first housing 200 to vibrate. The function module 100 can realize two functions of heat dissipation and vibration, so that the vibration module and the heat dissipation fan do not need to be additionally arranged, and further the reserved installation space of the electronic equipment is smaller, and the volume of the electronic equipment is smaller.
In order to improve the heat dissipation performance of the electronic device, in another alternative embodiment, the electronic device disclosed herein may further include a second housing 300 and a heat generating element 400, where both the second housing 300 and the heat generating element 400 may be located in the first inner cavity 210, and the heat generating element 400 may be thermally connected to the second housing 300. The heat generating member 400 may transfer the generated heat to the second housing 300 at this time.
The second housing 300 may be provided with a second inner cavity 310, the functional module 100 may be located in the second inner cavity 310, and the first housing 200 may be provided with a first air inlet and a first air outlet which are relatively arranged, where the first air inlet and the first air outlet are both communicated with the first inner cavity 210. The second housing 300 may be provided with a second air inlet and a second air outlet which are relatively arranged, the second air inlet and the second air outlet may be both communicated with the second inner cavity 310, and the first air inlet may be relatively connected with the second air inlet. The first air outlet may be opposite to the second air outlet and in communication.
In this scheme, the heat generated by the heating element 400 is transferred to the second housing 300, and under the effect of the heat dissipation function of the functional module 100, the flow of the gas in the second housing 300 is quickened, so that the heat transferred to the second housing 300 can be quickly dissipated, the aggregation of the heat on the electronic device is reduced, and the heat dissipation efficiency of the electronic device is improved.
Meanwhile, the second housing 300 forms a relatively independent gas flow space, and external cold gas enters the second inner cavity 310 through the first air inlet and the second air inlet, and is discharged out of the electronic device through the second air outlet and the first air outlet. The second cavity 310 has smaller wind resistance, thus having smaller influence on the gas flow, and thus having better heat dissipation effect.
Alternatively, the first air inlet and the first air outlet may be specifically formed on the frame of the first casing 200, and the parts forming the frame of the first casing 200 with different structures are different. For example, the first housing 200 may include a front case, a rear cover, and a middle frame disposed therebetween. The rim may be formed on the middle frame, in which case the rim is part of the middle frame. For another example, the first housing 200 may include a front cover and a rear cover, and the bezel is formed on the rear cover.
The heat generating component 400 in the above embodiment may be a central processing unit, a sensor, or other functional chips.
In another alternative embodiment, the second housing 300 and the heat generating component 400 may be connected by heat conduction through the heat conducting part 500, and at this time, the heat conducting performance between the second housing 300 and the heat generating component 400 can be improved, so that the heat dissipation performance of the electronic device is better.
Alternatively, the heat conducting portion 500 may be made of a heat conducting copper foil, a heat conducting silicone grease, or other materials, which is not limited herein.
Further, a heat dissipation plate 600 may be disposed on a side of the second housing 300 facing away from the heat conducting portion 500, and the heat dissipation plate 600 may be capable of performing auxiliary heat dissipation on the second housing 300, thereby improving heat dissipation efficiency of the electronic device. Alternatively, the heat sink 600 may be made of a metal material, although the heat sink may be made of other heat sink materials, which is not limited herein.
The electronic device disclosed in the embodiments of the present application may be a smart phone, a tablet computer, an electronic book reader, a wearable device (e.g., a smart watch), an electronic game machine, or the like, and the embodiments of the present application do not limit specific types of electronic devices.
The embodiments of the present application have been described above with reference to the accompanying drawings, but the present application is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and many forms may be made by those of ordinary skill in the art without departing from the spirit of the present application and the scope of the claims, which are also within the protection of the present application.
