Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to an electronic equipment. Background Art

[0002] During the use of electronic devices such as mobile phones, due to the influence of the operation of components such as processors and displays, the electronic devices will generate a certain amount of heat, which may affect the processing speed of the electronic devices and also have an adverse effect on the user's experience of holding the electronic devices.

[0003] In order to improve the heat dissipation speed of electronic devices, at present, structures such as heat sinks and heat conductive sheets are usually set on the surfaces of devices that generate relatively more heat in electronic devices to conduct the heat generated by the heat-generating devices to other locations in the electronic devices, thereby achieving the purpose of heat balance and reducing the temperature at the location where the heat-generating devices are located.

[0004] However, the above method belongs to passive heat dissipation technology, and its heat dissipation capacity is limited. As the power of the processor gradually increases, the above method cannot meet the heat dissipation requirements of electronic equipment. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem of poor heat dissipation effect of current electronic devices.

[0006] The embodiment of the present application provides an electronic device, which includes a rotating motor, a controllable coupling mechanism and a driven part. The rotating motor comprises a driving shaft, and the controllable coupling mechanisms are provided at opposite ends of the driving shaft, and each of the controllable coupling mechanisms is drivingly connected to the driven member, one of the two driven members comprises an eccentric member, and the other comprises a fan blade; Each of the controllable coupling mechanisms has a connected state and a disconnected state that can be switched with each other. When the controllable coupling mechanism is in the connected state, the drive shaft drives the driven part to rotate. When the controllable coupling mechanism is in the disconnected state, the drive shaft is disengaged from the driven part.

[0007] An embodiment of the present application discloses an electronic device, whose rotating motor includes a driving shaft. Controllable coupling mechanisms are arranged at both opposite ends of the driving shaft, and each controllable coupling mechanism is drivingly connected to a driven member. One of the driven members includes an eccentric member, and the other includes a fan blade. Therefore, in the electronic device disclosed in the embodiment of the present application, when the driving shaft rotates and each controllable coupling mechanism is working, the driving shaft can drive the eccentric member and the fan blade to rotate together, so that the electronic device can generate vibrations and perform active heat dissipation at the same time. Obviously, when the electronic device dissipates heat by means of active heat dissipation, the heat dissipation effect and efficiency of the electronic device can be significantly improved, and thus the user experience of the electronic device can be enhanced.

[0008] As described above, in the electronic device disclosed in the embodiment of the present application, the fan blade and the eccentric member share the same rotating motor, which greatly improves the utilization rate of the rotating motor. On the one hand, the cost can be reduced, and on the other hand, the total space occupied by the devices for providing vibration and active heat dissipation functions in the electronic device can also be reduced, which is conducive to the development of the electronic device towards the direction of being thinner and lighter.

[0009] In addition, in the embodiment of the present application, each controllable coupling mechanism has connectable and disconnectable states that can be switched with each other. When the controllable coupling mechanism is in the connected state, the driving shaft can drive the driven member to rotate. Correspondingly, when the controllable coupling mechanism is in the disconnected state, the driving shaft can be disengaged from the driven member, so that the corresponding driven member no longer provides the functions of vibration or active heat dissipation. Obviously, in this case, the electronic device can control the state of the corresponding controllable coupling mechanism based on its own needs or control commands, etc., and the electronic device has the ability to independently generate vibrations or perform active heat dissipation work, improving the customization requirements of the electronic device and reducing the power consumption of the electronic device, further enhancing the user experience.

Specific embodiments

[0012] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0013] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.

[0014] As Figures 1-5 shown, the embodiments of the present application disclose an electronic device. The electronic device may specifically include a mobile phone or a tablet computer, etc. The electronic device disclosed in the embodiments of the present application includes a fan blade 320, and the fan blade 320 can be driven to rotate, so as to accelerate the heat dissipation of other components in the electronic device by means of air cooling. That is, the electronic device disclosed in the embodiments of the present application adopts an active heat dissipation method to improve the overall heat dissipation efficiency and heat dissipation effect of the electronic device, so that the heat dissipation effect of the electronic device can be relatively good, and thus the user experience of the electronic device can be improved.

[0015] As described above, the electronic device disclosed in the embodiments of the present application includes a fan blade 320. In fact, currently, some manufacturers have installed an independent air-cooling mechanism in electronic devices such as mobile phones. The air-cooling mechanism is installed on one side or around the heat-dissipating device with relatively large heat generation and relatively large heat dissipation requirements, such as a processor, to enhance the heat dissipation efficiency and effect of the heat-dissipating device.

[0016] However, in currently available electronic devices equipped with an air-cooling mechanism, the air-cooling mechanism usually includes a separate air-cooling housing and a separate air-cooling electrode. The air-cooling electrode is connected to the fan blade 320 and both are installed in the air-cooling housing. Then, the entire air-cooling mechanism is installed on one side or around the heat-dissipating device. During actual use, the applicant found that the above technical solution would result in a relatively large space occupied by the air-cooling mechanism in the electronic device. Moreover, in the air-cooling mechanism, the air-cooling motor is only used to drive the fan blade 320 to work, and the utilization rate of the air-cooling motor is relatively low. As a result, the electronic device uses a relatively large space investment and cost investment to implement the above technical solution, but the effect output provided by the air-cooling mechanism in the electronic device is relatively low.

[0017] To address the above technical problems, in order to improve the utilization efficiency of the motor and minimize the overall space occupied by the mechanism providing the air-cooling function in the electronic device, after creative work, the applicant found that the vibration function is an essential function of the electronic device, and the device used to provide the vibration effect usually includes a driving motor and an eccentric member 310. When the electronic device needs to provide vibration, the driving motor is controlled to drive the eccentric member 310 to rotate, so that the electronic device generates a vibration effect. Based on this, the applicant found that the function of the motor used to provide the vibration effect in current electronic devices is also relatively single. Furthermore, the applicant creatively proposed to use the essential component in the electronic device, that is, the vibration motor, to provide driving effects for both the eccentric member 310 and the fan blade 320 at the same time, so that the vibration motor serves as a device with both the vibration function and the heat dissipation function, improving the utilization rate of the vibration motor. At the same time, only a fan blade 320 and a corresponding coupling structure need to be added at the position of the vibration motor in the electronic device. Compared with an independent air-cooling mechanism, this occupies much less space in the electronic device, and thus can also reduce the space occupied by the "air-cooling mechanism" to a certain extent, facilitating the development of the electronic device towards the direction of being thinner and lighter.

[0018] Based on the above situation, the applicant proposed the technical solution disclosed in the embodiments of the present application. As Figure 2 shown, the electronic device disclosed in the embodiments of the present application includes a rotating motor 100, a controllable coupling mechanism 200, and a driven member 300. It should be noted that the rotating motor 100 is the above-mentioned vibration motor.

[0019] Among them, the rotary electric machine 100 includes a drive shaft 110. Of course, the rotary electric machine 100 also includes devices such as a stator, a rotor, and a motor housing. The devices such as the stator and the rotor are all installed in the motor housing, and by supplying power to the rotary electric machine 100, the rotor can rotate around the stator, thereby driving the drive shaft 110 to rotate. In a specific embodiment of the present application, in order to improve the performance of the rotary electric machine 100, the rotary electric machine 100 can be a brushless motor.

[0020] Meanwhile, in the technical solution disclosed in the embodiment of the present application, controllable coupling mechanisms 200 are arranged at both opposite ends of the drive shaft 110, and each controllable coupling mechanism 200 is drivingly connected to a driven member 300. One of the two driven members 300 includes an eccentric member 310, and the other includes a fan blade 320. Obviously, when the drive shaft 110 is drivingly connected to the two driven members 300 (including the eccentric member 310 and the fan blade 320) respectively through the two controllable coupling mechanisms 200, the drive shaft 110 can drive the eccentric member 310 and the fan blade 320 to rotate synchronously. Obviously, when the eccentric member 310 rotates, the electronic device can generate vibrations; when the fan blade 320 rotates, a controllable air flow will be generated in the area where the fan blade 320 is located, thereby accelerating the heat dissipation efficiency of the electronic device.

[0021] It should be noted that the electronic device includes a housing 410, and the fan blade 320 is installed inside the housing 410 of the electronic device. Furthermore, in order to ensure that the fan blade 320 can transfer the heat of the heat-dissipating component in the electronic device, a corresponding air duct needs to be provided inside the housing 410 of the electronic device so that an air flow can be formed inside the electronic device and the location where the heat of the heat-dissipating component in the electronic device is transferred. In order to further improve the heat dissipation efficiency of the electronic device, in the embodiment of the present application, the housing 410 of the electronic device is provided with a first air inlet 411 and a first air outlet 412. At the same time, the fan blade 320 is located in the space connecting the first air inlet 411 and the first air outlet 412. In this case, when the fan blade 320 rotates, the gas outside the electronic device can enter the housing 410 of the electronic device through the first air inlet 411, and the gas originally located inside the housing 410 of the electronic device can be discharged outside the housing 410 of the electronic device through the first air outlet 412, achieving the purpose of gas replacement and further accelerating the heat dissipation efficiency of the electronic device.

[0022] Based on the above technical solution, after further consideration, the applicant realized that the scenarios where an electronic device has simultaneous requirements for vibration and active heat dissipation are relatively few. At the same time, the vibration requirement is usually intermittent, and the active heat dissipation requirement is usually continuous. Therefore, after further creative work, the applicant proposed to be able to flexibly control whether the controllable coupling mechanism 200 works according to actual needs. Accordingly, when the electronic device has a vibration requirement, the controllable coupling mechanism 200 between the drive shaft 110 and the eccentric member 310 is controlled to work. Correspondingly, when the electronic device has an active heat dissipation requirement, the controllable coupling mechanism 200 between the drive shaft 110 and the fan blade 320 is controlled to work. Of course, when the electronic device has simultaneous requirements for vibration and active heat dissipation, the controllable coupling mechanisms 200 on both sides of the drive shaft 110 can be made to work, so that the drive shaft 110 drives the eccentric member 310 and the fan blade 320 to work together, enabling the electronic device to perform active heat dissipation while vibrating.

[0023] It should be noted that in the controllable coupling mechanism 200, when the state of one or some of its components changes, the assembly relationship between the internal structures of the controllable coupling mechanism 200 can change accordingly, so that the controllable coupling mechanism 200 reciprocally switches between certain states. That is, the controllable coupling mechanism 200 can be controlled to switch from the working state to the non-working state, and vice versa, it can also switch from the non-working state to the working state.

[0024] Generally speaking, in the electronic device disclosed in the embodiments of the present application, each controllable coupling mechanism 200 has connectable and disconnectable states that can be mutually switched. When the controllable coupling mechanism 200 is in the connected state, the drive shaft 110 drives the driven member 300 to rotate. When the controllable coupling mechanism 200 is in the disconnected state, the drive shaft 110 is disengaged from the driven member 300. That is, when the drive shaft 110 rotates, it will not drive the driven member 300 to rotate synchronously. Correspondingly, the driven member 300 cannot provide the corresponding vibration or active heat dissipation function either.

[0025] It should be noted that when the controllable coupling mechanism 200 is in the above-mentioned connected state, it does not mean that there must be a spatial contact relationship between the corresponding components in the controllable coupling mechanism 200. The two can form a cooperative relationship through non-contact forces such as electric fields or magnetic fields, so as to form a transmission relationship between the drive shaft 110 and the driven member 300 connected by the controllable coupling mechanism 200, ensuring that the drive shaft 110 can drive the driven member 300 to rotate. That is, in the present application, during the process of the controllable coupling mechanism 200 switching between the connected state and the disconnected state, there may not be relative movement between the internal components of the controllable coupling mechanism 200, but only include the actions of applying and removing electric fields or magnetic fields.

[0026] An embodiment of the present application discloses an electronic device. Its rotating motor 100 includes a drive shaft 110. Controllable coupling mechanisms 200 are arranged at both opposite ends of the drive shaft 110. Each controllable coupling mechanism 200 is drivingly connected to a driven member 300. One of the driven members 300 includes an eccentric member 310, and the other includes a fan blade 320. Therefore, in the electronic device disclosed in the embodiment of the present application, when the drive shaft 110 rotates and each controllable coupling mechanism 200 is working, the drive shaft 110 can drive the eccentric member 310 and the fan blade 320 to rotate together, so that the electronic device can generate vibrations while also being able to perform active heat dissipation work. Obviously, when the electronic device dissipates heat by means of active heat dissipation, the heat dissipation effect and efficiency of the electronic device can be significantly improved, and thus the user experience of the electronic device can be enhanced.

[0027] As described above, in the electronic device disclosed in the embodiment of the present application, the fan blade 320 and the eccentric member 310 share the same rotating motor 100, which greatly improves the utilization rate of the rotating motor 100. On the one hand, it can reduce costs. On the other hand, it can also reduce the space occupied by the sum of the devices providing vibration and active heat dissipation functions in the electronic device, which is conducive to the development of the electronic device towards the direction of being thinner and lighter.

[0028] In addition, in the embodiment of the present application, each controllable coupling mechanism 200 has connectable and disconnectable states that can be switched with each other. When the controllable coupling mechanism 200 is in the connected state, the drive shaft 110 can drive the driven member 300 to rotate. Correspondingly, when the controllable coupling mechanism 200 is in the disconnected state, the drive shaft 110 can be disengaged from the driven member 300, so that the corresponding driven member 300 no longer provides the functions of vibration or active heat dissipation. Obviously, in this case, the electronic device can control the state of the corresponding controllable coupling mechanism 200 based on its own needs or control commands, etc., and the electronic device has the ability to independently generate vibrations or perform active heat dissipation work, improving the customization requirements of the electronic device and reducing the power consumption of the electronic device, further enhancing the user experience.

[0029] As described above, the controllable coupling mechanism 200 can change the state of one or some of its components, so that the assembly relationship between the internal structures of the controllable coupling mechanism 200 changes accordingly, enabling the controllable coupling mechanism 200 to reciprocally switch between the connected state and the disconnected state.

[0030] In a specific embodiment of the present application, the device for actively changing the state may be an electromagnet. Such a device can relatively flexibly and sensitively change its interaction relationship with other magnets by being energized or not. Moreover, the control difficulty of such a device is relatively low, and the effect is relatively good. It should be noted that the aforementioned active state change means that in the controllable coupling mechanism 200, the state change usually occurs first, and its state change is also controlled by the corresponding instructions of the electronic device or the user.

[0031] Based on the above situation, in a specific embodiment of the present application, the controllable coupling mechanism 200 includes a first mating portion 210, a second mating portion 220, a first magnet 230, and a second magnet 240. Among them, the first mating portion 210 is in transmission connection with the driving shaft 110, so that when the driving shaft 110 rotates, it can drive the first mating portion 210 to rotate synchronously. Correspondingly, the second mating portion 220 is in transmission connection with the driven member 300, so that when the second mating portion 220 rotates, the driven member 300 can rotate synchronously with the second mating portion 220. Specifically, between the first mating portion 210 and the driving shaft 110, and between the second mating portion 220 and the driven member 300, they can be fixedly connected by connecting members such as bolts, or a key connection can also be used to form a reliable transmission connection relationship between the first mating portion 210 and the driving shaft 110, and to form a reliable transmission connection relationship between the second mating portion 220 and the driven member 300.

[0032] At the same time, in the embodiment of the present application, the first magnet 230 is an electromagnet, and one of the first magnet 230 and the second magnet 240 is installed on the first mating portion 210. Correspondingly, the first magnet 230 and the second magnet 240 can be magnetically mated, so that in the embodiment of the present application, the magnetic mating relationship between the first magnet 230 and the second magnet 240 can be changed by changing the energization state in the first magnet 230, and further the purpose of changing the mating relationship between the first mating portion 210 and the second mating portion 220 can be achieved. Of course, in the embodiment of the present application, the other of the first magnet 230 and the second magnet 240 needs to be installed outside the first mating portion 210. For example, when the first magnet 230 is installed on the first mating portion 210, the second magnet 240 needs to be installed on a device other than the first mating portion 210 in the electronic device to ensure that when the first magnet 230 and the second magnet 240 generate magnetic interaction, the positional relationship between the first mating portion 210 and the second magnet 240 can be changed.

[0033] It should be noted that in the embodiments of the present application, the second magnet 240 can be an electromagnet. In this case, when the first magnet 230 is in the energized state, the second magnet 240 is also in the energized state, and the magnetic poles facing each other of the two are the same, so that a magnetic repulsive effect is generated between the two, which enables the first magnet 230 and the second magnet 240 to move away from each other.

[0034] In a possible implementation manner, when the first magnet 230 is in the de-energized state, the second magnet 240 also needs to be in the energized state, so that the second magnet 240 can generate a magnetic attraction on the iron core of the first magnet 230, and further enable the first magnet 230 and the second magnet 240 to approach each other. Alternatively, in order to make the magnetic attraction effect between the first magnet 230 and the second magnet 240 better, the pole distribution of the first magnet 230 can also be changed, so that the polarities of the magnetic poles of the first magnet 230 and the second magnet 240 that approach each other are opposite.

[0035] In a possible implementation manner, considering that whether the first magnet 230 is in the energized state, the de-energized state (or the pole-reversed state), the electromagnet as the second magnet 240 needs to be in the energized state. Furthermore, in order to further reduce the power consumption of the electronic device and reduce the control difficulty of the controllable coupling mechanism 200, in another embodiment of the present application, the second magnet 240 is a permanent magnet, and when the electromagnet as the first magnet 230 is in the energized state, the polarities of the magnetic poles of the second magnet 240 and the first magnet 230 that approach each other are the same to repel each other.

[0036] In the case of adopting the above technical solution, one of the first magnet 230 and the second magnet 240 can be installed on the first mating part 210, and the other can be installed on the second magnet 240, so that when the energized state of the first magnet 230 changes, the first magnet 230 and the second magnet 240 can drive the first mating part 210 and the second mating part 220 to approach or move away from each other, so that the first mating part 210 and the second mating part 220 can be switched between the connected state and the separated state.

[0037] More specifically, the first engaging portion 210 and the second engaging portion 220 have an insertable and engaging relationship. When they are inserted and engaged with each other, in the circumferential direction of the rotation of the drive shaft 110, the first engaging portion 210 and the second engaging portion 220 are relatively fixed, that is, they can rotate synchronously. In this case, when the first magnet 230 is energized and repels the second magnet 240, causing them to move away from each other, during the process of moving away from each other, the first engaging portion 210 and the second engaging portion 220 are separated, so that when the first engaging portion 210 rotates, it will not drive the second engaging portion 220 to rotate; conversely, when the first magnet 230 is de-energized, the iron core of the first magnet 230 can attract the second magnet 240, thereby causing the first engaging portion 210 and the second engaging portion 220 to approach each other to form an insertable and engaging relationship, and further enabling the first engaging portion 210 and the second engaging portion 220 to achieve the purpose of synchronous rotation.

[0038] Considering that the accuracy required for the first engaging portion 210 and the second engaging portion 220 to approach each other to form an insertable and engaging relationship is relatively high, during the working process, it may be caused by a slight deviation of one of the first engaging portion 210 and the second engaging portion 220, resulting in the inability to normally form an insertable and engaging relationship between the first engaging portion 210 and the second engaging portion 220, causing the controllable coupling mechanism 200 to fail.

[0039] Therefore, in another embodiment of the present application, in the controllable coupling mechanism 200, both the first engaging portion 210 and the second engaging portion 220 include friction plates. When the controllable coupling mechanism 200 is in a connected state, the friction plates of the first engaging portion 210 and the second engaging portion 220 are in contact with each other to link the first engaging portion 210 and the second engaging portion 220.

[0040] That is, in the embodiment of the present application, when the first magnet 230 and the second magnet 240 attract each other, the first engaging portion 210 and the second engaging portion 220 can be made to approach each other, and then the friction plates of the first engaging portion 210 and the second engaging portion 220 are in contact with each other. Under the action of friction, the first engaging portion 210 and the second engaging portion 220 form a linkage relationship. Then, when the drive shaft 110 rotates, the first engaging portion 210 and the second engaging portion 220 can rotate synchronously to drive the driven member 300 to rotate together, and provide a vibration or active heat dissipation function.

[0041] When the first engaging portion 210 and the second engaging portion 220 are linked to each other when the first magnet 230 and the second magnet 240 attract each other, if the first engaging portion 210 and the second engaging portion 220 are slightly separated due to accidental factors or the like, the attraction effect between the two will deteriorate, which may exacerbate the influence effect of the foregoing accidental factors, resulting in accidental separation between the first engaging portion 210 and the second engaging portion 220, and the first engaging portion 210 and the second engaging portion 220 cannot continue to transmit the rotational driving force.

[0042] Therefore, in another embodiment of the present application, when the first magnet 230 and the second magnet 240 repel each other, the first engaging portion 210 and the second engaging portion 220 can be made to approach each other to form a linkage relationship. In this case, even if affected by accidental factors, the first engaging portion 210 and the second engaging portion 220 are slightly separated, which will further enhance the magnetic repulsive force between the first magnet 230 and the second magnet 240. Thus, under the action of the magnetic force, the first engaging portion 210 and the second engaging portion 220 will approach each other again and restore a stable linkage relationship.

[0043] Furthermore, in the case of adopting the above technical solution, when one of the first magnet 230 and the second magnet 240 is installed on the first engaging portion 210, the first magnet 230 and the second magnet 240 can be both located on the side of the first engaging portion 210 facing away from the second engaging portion 220. Thus, when the first magnet 230 and the second magnet 240 repel each other, the first engaging portion 210 and the second engaging portion 220 approach each other, and when the first magnet 230 and the second magnet 240 attract each other, the first engaging portion 210 and the second engaging portion 220 move away from each other.

[0044] Of course, in order to ensure that the first magnet 230 can form an assembly relationship with components such as the housing 410 of the electronic device, in the embodiment of the present application, the controllable coupling mechanism 200 further includes a first bushing 250. The first bushing 250 is sleeved outside the drive shaft 110, and the drive shaft 110 is movably engaged with the first bushing 250. Specifically, an opening can be provided in the center of the first bushing 250, and the size of the opening is larger than the size of the first engaging portion 210 or the drive shaft 110, so as to ensure that the first bushing 250 can form a movable engagement relationship with both the drive shaft 110 (and the first engaging portion 210).

[0045] At the same time, in the embodiment of the present application, one of the first magnet 230 and the second magnet 240 is installed on the first matching portion 210, and the other is installed on the first sleeve 250, and when the controllable coupling mechanism 200 is in a connected state, the first magnet 230 is in a powered state, and the first magnet 230 and the second magnet 240 repel each other, so that the first matching portion 210 and the second matching portion 220 are close to each other, thereby forming a linkage relationship; and when the controllable coupling mechanism 200 is in a disconnected state, the first magnet 230 and the second magnet 240 attract each other, and the first matching portion 210 and the second matching portion 220 are moved away from each other, so that the linkage relationship between the two is released.

[0046] Similarly, when the controllable coupling mechanism 200 is in the disconnected state, the first magnet 230 can be in the power-off state, and the iron core of the first magnet 230 and the second magnet 240 can attract each other. Alternatively, the direction of the current passed through the first magnet 230 can be opposite, so that the polarities of the magnetic poles of the first magnet 230 and the second magnet 240 that are close to each other are different, which can also ensure that the first magnet 230 and the second magnet 240 can attract each other.

[0047] In order to reduce the difficulty of controlling the first magnet 230 and minimize the power consumption of the electronic device, in a specific embodiment of the present application, when the controllable coupling mechanism 200 is in a disconnected state, the first magnet 230 can be in a power-off state, thereby reducing the power consumption of the first magnet 230.

[0048] Of course, compared with the technical solution in which the first magnet 230 actively attracts the second magnet 240, the attraction effect between the second magnet 240 and the first magnet 230 in the power-off state is relatively poor. Based on this, in order to further improve the stability of the controllable coupling mechanism 200 in the disconnected state, in a specific embodiment of the present application, the controllable coupling mechanism 200 may also include a reset elastic member 270, and the reset elastic member 270 elastically abuts between the first mating portion 210 and the second mating portion 220. Of course, in order to ensure that the reset elastic member 270 can normally provide the reset driving force when the controllable coupling mechanism 200 is in the disconnected state, when the reset elastic member 270 is located between the first matching portion 210 and the second matching portion 220, when the controllable coupling mechanism 200 is in the connected state, the reset elastic member 270 is in a compressed state, so that after the first magnet 230 is powered off, the reset elastic member 270 can drive the second matching portion 220 to move in the direction close to the first matching portion 210, thereby ensuring that the first matching portion 210 and the second matching portion 220 can be spaced apart from each other to separate from each other.

[0049] In addition, the reset elastic member 270 can also be elastically squeezed between the second engaging portion 220 and the housing 410 of the electronic device, that is, the reset elastic member 270 is located on the side of the second engaging portion 220 away from the first engaging portion 210; alternatively, one end of the reset elastic member 270 can also be fixedly connected to the first engaging portion 210, and the other end of the reset elastic member 270 can be fixedly connected to the first bushing 250. Based on this, when the controllable coupling mechanism 200 is in the connected state, the reset elastic member 270 can be in a stretched state. Correspondingly, after the first magnet 230 is powered off, the reset elastic member 270 can also drive the first engaging portion 210 to move away from the second engaging portion 220.

[0050] When the reset elastic member 270 is located between the first engaging portion 210 and the second engaging portion 220, if the first engaging portion 210 and the second engaging portion 220 are separated from each other, and the first engaging portion 210 rotates with the drive shaft 110, relative friction will be generated between the reset elastic member 270 and the first engaging portion 210. Furthermore, in order to reduce noise and prevent the reset elastic member 270 from interfering with the normal rotation of the first engaging portion 210, devices such as bearings can be provided on the side of the first engaging portion 210 facing the second engaging portion 220, and the end of the reset elastic member 270 away from the second engaging portion 220 can be abutted against the bearing, so that a stable rotational mating relationship is formed between the first engaging portion 210 and the reset elastic member 270.

[0051] As described above, considering that the first magnet 230 is an electromagnet and the second magnet 240 can be a permanent magnet. Furthermore, when the second magnet 240 is a permanent magnet, as Figure 3 and Figure 4 shown, the second magnet 240 can be installed on the first engaging portion 210, and the first magnet 230 can be located on the side of the second magnet 240 away from the second engaging portion 220. Specifically, the first magnet 230 can be installed on the first bushing 250. In this case, since the first magnet 230 (and the first bushing 250) does not rotate with the first engaging portion 210, a stable relative fixed relationship can be formed between the first magnet 230 and devices such as the housing 410 of the electronic device. Furthermore, the power connection difficulty of the first magnet 230 can be reduced, and the reliability of the first magnet 230 can be improved.

[0052] Optionally, the controllable coupling mechanism 200 further includes a second bushing 260, and both the second bushing 260 and the first bushing 250 can be directly or indirectly fixedly connected to the housing 410 of the electronic device. The second engaging portion 220 can be installed inside the second bushing 260, and the second engaging portion 220 is movably engaged with the second bushing 260. Of course, bearings and other devices can be provided between the first bushing 250 and the first engaging portion 210, and between the second bushing 260 and the second engaging portion 220 to improve the rotational stability of the first engaging portion 210 and the second engaging portion 220. In the case of adopting this technical solution, the first bushing 250 and the second bushing 260 can provide a protective effect for the first engaging portion 210, the second engaging portion 220, and the reset elastic member 270, preventing external dust and other impurities from entering between the first engaging portion 210 and the second engaging portion 220, and thus having an adverse effect on the linkage relationship between the two.

[0053] As described above, the controllable coupling mechanism 200 includes a first engaging portion 210, a second engaging portion 220, a first magnet 230, and a second magnet 240, which can change the distance between the first engaging portion 210 and the second engaging portion 220 by the mutual attraction or repulsion between the first magnet 230 and the second magnet 240, so that the first engaging portion 210 and the second engaging portion 220 are in a linkage state or a separated state.

[0054] Therefore, in the case of adopting the above technical solution, the first engaging portion 210 and the second engaging portion 220 also need to be in spatial contact or connection with each other. In order to prevent the rotating motor 100 from being overloaded when the driven member 300 is stuck or the like, in another embodiment of the present application, the controllable coupling mechanism 200 is a magnetic coupling, that is, in the embodiment of the present application, whether or not a linkage relationship is formed between the first engaging portion 210 and the second engaging portion 220, there is no contact relationship or connection relationship between the first engaging portion 210 and the second engaging portion 220 in space. Furthermore, when the driven member 300 is stuck or the like, relative movement can occur between the first engaging portion 210 and the second engaging portion 220, preventing the rotating motor 100 from being damaged due to overload. Moreover, in the case of adopting the embodiment of the present application, the power consumption of the controllable coupling mechanism 200 can be further reduced, its service life can be improved, and the maintenance cycle can be significantly extended.

[0055] As described above, the electronic device disclosed in the embodiment of the present application includes a fan blade 320, and the fan blade 320 is located in the housing 410 of the electronic device. At the same time, an air duct can be formed in the housing 410 so that the gas in the air duct of the electronic device can be replaced with the gas outside the electronic device.

[0056] In another embodiment of the present application, in order to further improve the controllability of active heat dissipation, the air duct of the fan blade 320 can be made independent. Specifically, the electronic device includes a housing 410 and a mounting housing 420. The mounting housing 420 is installed within the housing 410, and the fan blade 320 is installed within the mounting housing 420. The housing 410 is provided with a first air inlet 411 and a first air outlet 412, and the mounting housing 420 is provided with a second air inlet 423 and a second air outlet 424. The second air inlet 423 is communicated with the first air inlet 411, and the second air outlet 424 is communicated with the first air outlet 412. Among them, parameters such as the shapes and sizes of the first air inlet 411, the first air outlet 412, the second air inlet 423, and the second air outlet 424, and the positions of the first air inlet 411 and the first air outlet 412 on the housing 410 are not limited in this article. Of course, a relatively reliable sealing fit relationship needs to be formed between the first air inlet 411 and the second air inlet 423, and between the first air outlet 412 and the second air outlet 424.

[0057] That is to say, in the above-mentioned embodiment of the present application, by providing a separate housing structure for the fan blade 320, the air duct for controlling the gas flow path can have relatively stronger sealing performance, so as to further improve the active heat dissipation effect. At the same time, in the case of adopting the above technical solution, it can also prevent impurities such as water vapor and dust outside the electronic device from directly entering the interior of the electronic device through the first air inlet 411, thereby damaging the internal components of the electronic device and improving the reliability and service life of the electronic device. More specifically, in order to facilitate the assembly of structures such as the fan blade 320, the mounting housing 420 can include a first housing 421 and a second housing 422, which are connected to each other by connecting parts such as adhesives or screws. The specific shapes and sizes of the first housing 421 and the second housing 422 and other parameters are not limited in this article.

[0058] At the same time, in the case where the electronic device includes the mounting housing 420, the rotating motor 100 and the controllable coupling mechanism 200 can also be arranged within the mounting housing 420 together, so as to use the mounting housing 420 to provide a protective effect for the rotating motor 100 and the controllable coupling mechanism 200, and can also reduce the assembly difficulty between the fan blade 320, the controllable coupling mechanism 200 and the rotating motor 100. Of course, for the eccentric member 310, it can also be arranged within the mounting housing 420. In addition, in an electronic device that includes using the rotating motor 100 and the eccentric member 310 to provide a vibration function, the rotating motor 100 and the eccentric member 310 are also provided with a housing structure. Furthermore, in the electronic device disclosed in the embodiments of the present application, the original housing structure of the eccentric member 310 can be adaptively improved to form the mounting housing 420, and the fan blade 320 can be installed within the mounting housing 420 together.

[0059] Further, in order to improve the working efficiency of the fan blade 320, during the process of arranging the fan blade 320 in the installation shell 420, the fan blade 320 can be located between the second air inlet 423 and the second air outlet 424.

[0060] In addition, when both the rotating motor 100 and the controllable coupling mechanism 200 are arranged in the housing, in order to prevent the rotating motor 100 and the controllable coupling mechanism 200 from obstructing the air flow, the rotating motor 100 and the controllable coupling mechanism 200 can be located outside the area between the second air inlet 423 and the second air outlet 424. More specifically, as Figure 1 shown, the rotating motor 100, the controllable coupling mechanism 200, and the fan blade 320 can be distributed in a direction perpendicular to the distribution direction of the second air inlet 423 and the second air outlet 424.

[0061] As described above, the electronic device includes heat-dissipating components such as a processor. Based on the above embodiments, the heat-dissipating component is in thermal conduction cooperation with the surface of the installation shell 420. For example, during the assembly process of the electronic device, the installation shell 420 can be located on one side of the heat-dissipating component. Specifically, the installation shell 420 and the heat-dissipating component can be distributed along the thickness direction of the electronic device, and the heat-dissipating component is arranged in surface contact with the installation shell 420, so that the heat generated by the heat-dissipating component can be directly transferred to the installation shell 420, and then during the flow of the gas, the heat can be dissipated outside the electronic device more quickly. In other embodiments of the present application, considering that the thickness dimension of the electronic device is usually relatively small, furthermore, the heat-dissipating component and the installation shell 420 can also be arranged in a staggered manner in the thickness direction of the electronic device. For example, the two can be spaced apart along the length direction of the electronic device. In this case, a heat-conducting sheet such as graphite can be used to connect the heat-dissipating component and the installation shell 420 to ensure that the heat of the heat-dissipating component can still be conducted to the installation shell 420 quickly and thoroughly, and dissipated outside the electronic device under the action of the gas flow.

[0062] As described above, the installation shell 420 and the heat-dissipating component can be distributed in sequence along the thickness direction of the electronic device, and the two can also be distributed in a staggered manner along the thickness direction, so that the thickness dimension of the electronic device will not be affected by the overall thickness of the installation shell 420 and the heat-dissipating component. In order to further reduce the thickness dimension of the installation shell 420, and further reduce the space occupied by the rotating motor 100 in the thickness direction of the electronic device, and further make the thickness dimension of the entire controllable coupling mechanism 200 relatively smaller. In a specific embodiment of the present application, the axial direction of the fan blade 320 can be parallel to the thickness direction of the electronic device, and the rotation direction of the drive shaft 110 is perpendicular to the thickness direction of the electronic device.

[0063] Generally, the axial dimension of the fan blade 320 is smaller than its dimension in the direction perpendicular to the axial direction. Similarly, the radial dimension of the drive shaft 110 is also smaller than its axial dimension. Furthermore, in the case of adopting the above technical solution, the space occupied by the entire controllable coupling mechanism 200 in the thickness direction of the electronic device is relatively smaller. Or rather, in the case of adopting the above technical solution, the radial dimension of the fan blade 320 can also be appropriately increased to further improve the active heat dissipation performance of the electronic device.

[0064] Of course, in the case of adopting the above technical solution, since the axial direction of the fan blade 320 is perpendicular to the axial direction of the drive shaft 110, a direct transmission cooperation relationship cannot be formed between the two through the controllable coupling mechanism 200. For this reason, in the embodiment of the present application, the electronic device further includes a transmission mechanism 500, and the fan blade 320 is in transmission connection with the corresponding controllable coupling mechanism 200 through the transmission mechanism 500.

[0065] That is to say, the transmission mechanism 500 has the ability to change the extension direction of the transmission shaft. Specifically, the transmission mechanism 500 may include a worm and worm gear. In order to improve the transmission accuracy of the transmission mechanism 500, in another embodiment of the present application, the transmission mechanism 500 includes a first bevel gear 510 and a second bevel gear 520 that are in transmission connection. The first bevel gear 510 is in transmission connection with the controllable coupling mechanism 200, and the second bevel gear 520 is in transmission connection with the fan blade 320. More specifically, the second bevel gear 520 may further be provided with a gear shaft, and the gear shaft may be rotatably installed in the installation shell 420, thereby further improving the stability of the transmission mechanism 500.
