[0031] Combine the following Figures 1 to 7 A linear motor 100 and an electronic device 200 according to an embodiment of the present application are described.
[0032] First, as Figures 1 to 5 As shown, the embodiment of the present application provides a linear motor 100, including: a housing 110, with a first opening 112 and a second opening 114 respectively disposed at both ends of the housing 110; a motor vibrator 130 disposed in the housing 110, and the motor vibrator 130 can reciprocate along a first direction AB; a first fan blade 140 disposed in the housing 110, opposite to the first opening 112, and located on one side of the motor vibrator 130 along the first direction AB; a second fan blade 150 disposed in the housing 110, opposite to the first opening 112, and located on one side of the motor vibrator 130 along the first direction AB; Opposite to the opening 114, along the first direction AB, the second fan blade 150 is located on the other side of the motor vibrator 130; wherein, the motor vibrator 130 can drive the first fan blade 140 and the second fan blade 150 to move, when the motor vibrator 130 vibrates, the first fan blade 140 moves, so that the airflow enters the shell 110 through the first opening 112 and is discharged from the shell 110 through the second opening 114; the second fan blade 150 moves, so that the airflow enters the shell 110 through the second opening 114 and is discharged from the shell 110 through the first opening 112.
[0033] In an embodiment of the present application, the linear motor 100 includes a shell 110 and a motor vibrator 130, wherein the two ends of the shell 110 respectively have a first opening 112 and a second opening 114, the motor vibrator 130 is arranged in the shell 110, and the motor vibrator 130 can reciprocate along the first direction AB, thereby realizing the vibration effect of the linear motor 100.
[0034] The linear motor 100 also includes a first blade 140 and a second blade 150, which are arranged in the shell 110, and the first blade 140, the motor vibrator 130 and the second blade 150 are distributed along the first direction AB, the first blade 140 is opposite to the first opening 112, and the first blade 140 is located between the first opening 112 and the motor vibrator 130, the second blade 150 is opposite to the second opening 114, and the second blade 150 is located between the second opening 114 and the motor vibrator 130.
[0035] Among them, when the motor vibrator 130 moves along the first direction AB, the first fan blade 140 and the second fan blade 150 can be driven to move. Specifically, when the motor vibrator 130 vibrates, the first fan blade 140 moves, so that the airflow enters the shell 110 from the first opening 112 and is discharged from the shell 110 through the second opening 114. Similarly, when the motor vibrator 130 vibrates, the second fan blade 150 moves, so that the airflow enters the shell 110 from the second opening 114 and is discharged from the shell 110 through the first opening 112, thereby realizing ventilation of the space on both sides of the linear motor 100, thereby realizing thermal interaction and achieving the effect of active heat dissipation.
[0036] As mentioned above, the linear motor 100 provided in the present application has the ability of active heat dissipation, that is, the linear motor 100 has multiple functions such as vibration and active heat dissipation. If the linear motor 100 is set in the electronic device 200, there is no need to set up independent heat dissipation components such as fans, and only one set of circuits needs to be arranged, which reduces the occupation of the internal space of the electronic device 200, is conducive to the lightweight of the electronic device 200, and can improve the heat dissipation effect of the electronic device 200.
[0037] That is, the linear motor 100 provided in the present application can discharge the high-temperature air inside the electronic device 200 to the outside of the electronic device 200, and draw the low-temperature air outside the electronic device 200 into the inside of the electronic device 200, thereby achieving efficient and reliable heat dissipation capabilities, and, when the motor vibrator 130 vibrates at a high frequency, the airflow can circulate rapidly, thereby significantly improving the heat dissipation performance of the linear motor 100.
[0038] Furthermore, the present application increases the functionality of the linear motor 100 and reuses the motor vibrator 130 as a driving element, which requires a smaller stacking space than adding an independent rotor fan, thereby saving the internal space of the electronic device 200.
[0039] The housing 110 may be made of plastic, plastic or metal, and the use of the linear motor 100 of the present application may eliminate or reduce the graphite film and the heat spreader, thereby helping to reduce the weight and thickness of the electronic device 200.
[0040] Specifically, the vibration frequency of the motor vibrator 130 can be adjusted according to the heating condition of the electronic device 200, that is, by monitoring the temperature inside the electronic device 200 through software and then controlling the working frequency of the linear motor 100, the intensity of heat dissipation can be autonomously adjusted.
[0041] The linear motor 100 may be an X-axis linear motor, a Y-axis linear motor, or a Z-axis linear motor.
[0042] like Figures 1 to 5As shown, as a possible embodiment, the shell 110 includes: a first shell 116, a first opening 112 and a second opening 114 are arranged on the first shell 116; a second shell 118 is arranged in the first shell 116, at least part of the motor vibrator 130 is located inside the second shell 118, and the first fan blade 140 and the second fan blade 150 are located between the first shell 116 and the second shell 118; wherein, when the motor vibrator 130 vibrates, the first fan blade 140 moves, so that the airflow enters the space between the first shell 116 and the second shell 118 from the first opening 112, and is discharged from the first shell 116 through the second opening 114; the second fan blade 150 moves, so that the airflow enters the space between the first shell 116 and the second shell 118 from the second opening 114, and is discharged from the first shell 116 through the first opening 112.
[0043] Specifically, the shell 110 includes a first shell 116 and a second shell 118, and the second shell 118 is located inside the first shell 116. The second shell 118 can be a convex rib protruding from the inner wall of the first shell 116, or it can be an independent shell 110 structure, wherein at least part of the structure of the motor vibrator 130 is located inside the second shell 118, and the first fan blade 140 and the second fan blade 150 are located between the first shell 116 and the second shell 118.
[0044] When the motor vibrator 130 vibrates, the first fan blade 140 moves, causing the airflow to enter between the first shell 116 and the second shell 118 from the first opening 112 and be discharged from the first shell 116 through the second opening 114. Similarly, when the motor vibrator 130 vibrates, the second fan blade 150 moves, causing the airflow to enter between the first shell 116 and the second shell 118 from the second opening 114 and be discharged from the first shell 116 through the first opening 112, thereby achieving the exchange of gas and heat. In addition, by protecting the motor vibrator 130 within the second shell 118, the impact of the airflow on the motor vibrator 130 can be reduced, and a flow channel can be formed between the first shell 116 and the second shell 118, thereby facilitating the guidance of the airflow and helping to increase the flow rate of the airflow.
[0045] like Figures 1 to 5 As shown, as a possible implementation, a first flow channel 120 and a second flow channel 122 are formed between the first shell 116 and the second shell 118, and the first flow channel 120 and the second flow channel 122 are distributed along the second direction CD, and the second direction CD is perpendicular to the first direction AB; wherein, when the motor vibrator 130 vibrates, the first fan blade 140 moves, so that the airflow enters the first flow channel 120 from the first opening 112 and is discharged from the first shell 116 through the second opening 114; the second fan blade 150 moves, so that the airflow enters the second flow channel 122 from the second opening 114 and is discharged from the first shell 116 through the first opening 112.
[0046] Specifically, a first flow channel 120 and a second flow channel 122 are formed between the first shell 116 and the second shell 118, and the first flow channel 120 and the second flow channel 122 are distributed along the second direction CD, and the second direction CD is perpendicular to the first direction AB. When the motor vibrator 130 vibrates, the first fan blade 140 moves, so that the airflow enters the first flow channel 120 from the first opening 112 and is discharged from the first shell 116 through the second opening 114. Similarly, when the motor vibrator 130 vibrates, the second fan blade 150 moves, so that the airflow enters the second flow channel 122 from the second opening 114 and is discharged from the first shell 116 through the first opening 112.
[0047] Therefore, the airflows in two directions are guided respectively through the first flow channel 120 and the second flow channel 122 , thereby reducing the interference between the airflows in the two directions, ensuring the flow rate of the airflow, and ensuring the effect of heat exchange.
[0048] Furthermore, the first flow channel 120 and the second flow channel 122 share the first opening 112 and the second opening 114 , thereby reducing the number of openings on the electronic device 200 and making it easier to hide the air inlet and outlet.
[0049] The number of the first flow channel 120 may be one, two or more, and the number of the second flow channel 122 may be one, two or more.
[0050] like Figures 1 to 5 As shown, as a possible implementation, it also includes: a first one-way valve 160, which is arranged in the first flow channel 120, and the first one-way valve 160 is connected in the direction from the first opening 112 to the second opening 114; a second one-way valve 170, which is arranged in the second flow channel 122, and the second one-way valve 170 is connected in the direction from the second opening 114 to the first opening 112.
[0051] Specifically, the linear motor 100 also includes a first one-way valve 160 and a second one-way valve 170. The first one-way valve 160 is arranged in the first flow channel 120, and the first one-way valve 160 is connected from the first opening 112 to the second opening 114, so that the airflow can enter the first flow channel 120 from the direction of the first opening 112 and be discharged from the first flow channel 120 from the direction of the second opening 114; the second one-way valve 170 is arranged in the second flow channel 122, and the second one-way valve 170 is connected from the second opening 114 to the first opening 112, so that the airflow can enter the second flow channel 122 from the direction of the second opening 114 and be discharged from the first flow channel 120 from the direction of the first opening 112.
[0052] As configured above, the first flow channel 120 and the second flow channel 122 can achieve unidirectional flow guidance, so that the airflow flows more smoothly, the mutual interference between the airflows is reduced, and the heat dissipation capacity of the linear motor 100 is improved.
[0053] like Figures 1 to 5 As shown, as a possible implementation, there are two first one-way valves 160 , which are respectively arranged at both ends of the first flow channel 120 ; there are two second one-way valves 170 , which are respectively arranged at both ends of the second flow channel 122 .
[0054] Specifically, there can be two first one-way valves 160, which are respectively arranged at both ends of the first flow channel 120; there can be two second one-way valves 170, which are respectively arranged at both ends of the second flow channel 122, so as to realize the closing and opening of the first flow channel 120 and the second flow channel 122, ensure that the airflow flows through a single first flow channel 120 or the second flow channel 122, reduce the loss of airflow, and ensure that the airflow passes through the first flow channel 120 or the second flow channel 122.
[0055] like Figures 1 to 5 As shown, as a possible implementation, it also includes: a first reset member 180, connecting the first fan blade 140 and the shell 110, or connecting the first fan blade 140 and the motor vibrator 130, the motor vibrator 130 is used to drive the first fan blade 140 to approach the first opening 112, and the first reset member 180 is used to drive the first fan blade 140 away from the first opening 112; a second reset member 190, connecting the second fan blade 150 and the shell 110, or connecting the second fan blade 150 and the motor vibrator 130, the motor vibrator 130 is used to drive the second fan blade 150 to approach the second opening 114, and the second reset member 190 is used to drive the second fan blade 150 away from the second opening 114.
[0056] Specifically, the linear motor 100 also includes a first reset member 180 and a second reset member 190, one end of the first reset member 180 is connected to the first fan blade 140, and the other end is connected to the shell 110, or one end of the first reset member 180 is connected to the first fan blade 140, and the other end is connected to the motor vibrator 130, so that the motor vibrator 130 can drive the first fan blade 140 to approach the first opening 112, and the first reset member 180 can drive the first fan blade 140 away from the first opening 112, so that the first fan blade 140 moves towards and away from the first opening 112. After the motor vibrator 130 drives the first fan blade 140 to move close to the first opening 112, a negative pressure space is formed on the side of the first fan blade 140 away from the first opening 112, and then the first reset member 180 drives the first fan blade 140 away from the first opening 112. The airflow outside the first opening 112 is affected by the pressure and enters the shell 110 through the first opening 112, and then is discharged through the second opening 114.
[0057] One end of the second reset member 190 is connected to the second fan blade 150, and the other end is connected to the shell 110, or one end of the second reset member 190 is connected to the second fan blade 150, and the other two ends are connected to the motor vibrator 130, so that the motor vibrator 130 can drive the second fan blade 150 to approach the second opening 114, and the second reset member 190 can drive the second fan blade 150 away from the second opening 114, so that the second fan blade 150 moves towards and away from the second opening 114. After the motor vibrator 130 drives the second fan blade 150 to move towards the second opening 114, a negative pressure space is formed on the side of the second fan blade 150 away from the second opening 114. Thereafter, the second reset member 190 drives the second fan blade 150 away from the second opening 114, and the airflow outside the second opening 114 is affected by the pressure and enters the shell 110 through the second opening 114, and then is discharged through the first opening 112.
[0058] As described above, through the cooperation of the motor vibrator 130, the first reset member 180 and the second reset member 190, the first fan blade 140 and the second fan blade 150 can reciprocate, thereby realizing a continuous flow of airflow and improving the heat dissipation capacity of the linear motor 100. In addition, the above driving method can reduce the influence of the first fan blade 140 and the second fan blade 150 on the motor vibrator 130, thereby ensuring the vibration effect of the motor vibrator 130.
[0059] like Figures 1 to 5 As shown, as a possible embodiment, the motor vibrator 130 includes: a vibrator body 132, located inside the shell 110; a first pushing portion 134, arranged at one end of the vibrator body 132, and the first pushing portion 134 is used to push the first fan blade 140; a second pushing portion 136, arranged at the other end of the vibrator body 132, and the second pushing portion 136 is used to push the second fan blade 150.
[0060] Specifically, the motor vibrator 130 includes a vibrator body 132, a first pushing portion 134 and a second pushing portion 136. The first pushing portion 134 and the second pushing portion 136 are respectively arranged at two ends of the motor vibrator 130. The first pushing portion 134, the motor vibrator 130 and the second pushing portion 136 are distributed along the first direction AB. The first pushing portion 134 can push the first fan blade 140 to move, and the second pushing portion 136 can push the second fan blade 150 to move.
[0061] The number of the first pushing portion 134 may be one, two, or more, etc. The number of the second pushing portion 136 may be one, two, or more, etc.
[0062] The motor vibrator 130 has a first pushing portion 134 and a second pushing portion 136, and the two pushing portions protrude from both ends of the vibrator body 132 respectively, and the first pushing portion 134 and the second pushing portion 136 are designed to be symmetrical on the left and right. When the motor vibrator 130 moves to the left, the first pushing portion 134 pushes the first fan blade 140 to move to the left, so that the gas enters through the first opening 112 and is discharged through the second opening 114. The second pushing portion 136 pushes the second fan blade 150 to move to the right, so that the gas enters through the second opening 114 and is discharged through the first opening 112.
[0063] like Figure 6 As shown, as a possible implementation, the motor vibrator 130 includes: a vibrator body 132, located inside the shell 110; a push rod 138, passing through the vibrator body 132, the push rod 138 protrudes from the vibrator body 132 at one end to form a first pushing portion 134, the first pushing portion 134 is used to push the first fan blade 140, and the push rod 138 protrudes from the vibrator body 132 at the other end to form a second pushing portion 136, the second pushing portion 136 is used to push the second fan blade 150.
[0064] Specifically, the motor vibrator 130 includes a vibrator body 132 and a push rod 138. The push rod 138 is passed through the vibrator body 132 and protrudes from both ends of the vibrator body 132. A first pushing portion 134 is formed at one end of the vibrator body 132, and a second pushing portion 136 is formed at the other end of the vibrator body 132. The first pushing portion 134, the motor vibrator 130 and the second pushing portion 136 are distributed along the first direction AB. The first pushing portion 134 can push the first fan blade 140 to move, and the second pushing portion 136 can push the second fan blade 150 to move.
[0065] The number of the push rods 138 may be one, two, or more, etc. The number of the first push portion 134 and the second push portion 136 may be one, two, or more, etc.
[0066] The first pushing portion 134 and the second pushing portion 136 are designed to be symmetrical on the left and right. When the motor vibrator 130 moves to the left, the first pushing portion 134 pushes the first fan blade 140 to move to the left, so that the gas enters through the first opening 112 and is discharged through the second opening 114. The second pushing portion 136 pushes the second fan blade 150 to move to the right, so that the gas enters through the second opening 114 and is discharged through the first opening 112.
[0067] Specifically, the exhaust process of the linear motor 100 provided in the present application is as follows: Figure 2As shown, when the motor vibrator 130 moves to the leftmost side along the first direction AB, the stroke reaches the maximum value, and the first fan blade 140 is also pushed to the leftmost side by the first pushing portion 134. At this time, the first fan blade 140 and the cavity wall of the shell 110 form a low-pressure environment, and the motor vibrator 130 begins to move to the right. At this time, the first fan blade 140 loses the support of the first pushing portion 134, and is reset to the right side under the action of the first reset member 180. Under the condition of the pressure difference between the inside and outside of the shell 110, a large amount of air enters the shell 110 from the first opening 112. At this time, the two first one-way valves 160 are opened, and the low-temperature airflow quickly flows along the first flow channel 120 to the other side of the motor vibrator 130, and is discharged through the second opening 114, thereby achieving the purpose of heat dissipation.
[0068] like Figure 3 As shown, when the motor vibrator 130 moves to the middle position along the first direction AB, the first fan blade 140 is reset, and then the motor vibrator 130 continues to move to the right, and the second pushing portion 136 begins to lift the second fan blade 150, and begins to accelerate the discharge of low-temperature air until the motor vibrator 130 moves to the rightmost position.
[0069] like Figure 4 As shown, when the motor vibrator 130 moves to the rightmost side along the first direction AB, the stroke reaches the maximum value and the low-temperature air is exhausted. At this time, the second fan blade 150 and the cavity wall of the shell 110 form a low-pressure environment. At the same time, the motor vibrator 130 begins to move to the left. At this time, the second fan blade 150 loses the support of the second pushing portion 136 and is reset to the left under the action of the second reset member 190. Under the condition of the internal and external pressure difference of the shell 110, a large amount of air enters the shell 110 from the second opening 114. At this time, the two second one-way valves 170 are opened, and the low-temperature airflow quickly flows along the second flow channel 122 to the other side of the motor vibrator 130 and is discharged through the first opening 112, thereby achieving the effect of quickly completing the heat exchange.
[0070] Among them, the first flow channel 120 can flow air from the outside of the electronic device 200 to the inside of the electronic device 200, and the second flow channel 122 can flow air from the inside of the electronic device 200 to the outside of the electronic device 200; or the first flow channel 120 can flow air from the inside of the electronic device 200 to the outside of the electronic device 200, and the second flow channel 122 can flow air from the outside of the electronic device 200 to the inside of the electronic device 200.
[0071] like Figure 5As shown, when the linear motor 100 works at a high frequency, the interior of the linear motor 100 will reciprocate to realize the process of air intake and exhaust. The first flow channel 120 of the linear motor 100 will continuously inhale the low-temperature air outside the electronic device 200, and the second flow channel 122 will continuously discharge the high-temperature air inside the electronic device 200, thereby forming an internal and external airflow exchange system to achieve the purpose of heat dissipation. Figure 5 The arrow in the middle indicates the direction of air flow.
[0072] Second, as Figure 7 As shown, an embodiment of the present application provides an electronic device 200, including: a device body 210; and a linear motor 100 as provided in the embodiment of the first aspect, wherein the linear motor 100 is disposed in the device body 210.
[0073] The electronic device 200 provided in the embodiment of the present application includes the linear motor 100 provided in the embodiment of the first aspect, and therefore has all the beneficial effects of the linear motor 100 provided in the embodiment of the first aspect, which will not be described one by one here.
[0074] like Figure 7 As shown, as a possible implementation, the device body 210 has a ventilation channel 220 and a sound outlet 230 , the ventilation channel 220 is connected to one of the first opening 112 and the second opening 114 of the linear motor 100 , and the ventilation channel 220 is also connected to the sound outlet 230 .
[0075] Specifically, the device body 210 has a ventilation channel 220 and a sound outlet 230. The ventilation channel 220 is connected to one of the first opening 112 and the second opening 114 of the linear motor 100, and the sound outlet 230, so that the hot air flow in the device body 210 can be discharged from the device body 210 through the linear motor 100 and the sound outlet 230, and the cold air flow outside the device body 210 can enter the device body 210 through the sound outlet 230 and the linear motor 100, thereby completing the heat exchange of the device body 210 and improving the heat dissipation effect of the device body 210. In addition, there is no need to set heat dissipation holes, which reduces the production difficulty of the electronic device 200 and improves the production efficiency of the electronic device 200.
[0076] By reusing the sound outlet 230 as a heat dissipation and ventilation outlet, there is no need to open an additional hole on the outside of the electronic device 200, thereby reducing the impact on the appearance of the electronic device 200.
[0077] The electronic device 200 may be a terminal, or may be other devices except the electronic device 200. Exemplarily, the electronic device 200 may be a mobile phone, a tablet computer, a laptop computer, a PDA, an in-vehicle electronic device, a music player, a private network communication terminal device (such as a walkie-talkie), a mobile Internet device (Mobile Internet Device, MID), an augmented reality / virtual reality / mixed reality device, a robot, a wearable device, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a netbook or a personal digital assistant (personal digital assistant, PDA), etc., and may also be a server, a network attached storage (Network Attached Storage, NAS), a personal computer (personal computer, PC), a television (television, TV), a teller machine or a self-service machine, etc., which is not specifically limited in the embodiments of the present application.
