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] At present, with the continuous improvement of the performance of electronic devices and the complexity of user usage environment, electronic devices have stronger heat dissipation requirements.

[0003] In the related art, some electronic devices have built-in fans and air outlets on the casing. When the fan is running, the heat inside the electronic device can be discharged from the air outlet in the form of airflow. However, the air outlet is exposed on the surface of the electronic device, which makes it easy for dust or liquid to enter the air outlet, thereby easily causing damage to the fan. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide an electronic device that can effectively solve the technical problem that debris is easily introduced into the air outlet of the electronic device with active heat dissipation function.

[0005] An embodiment of the present application provides an electronic device, including:

[0006] The device body comprises a first cavity and an air inlet, and the first cavity and the air inlet are connected;

[0007] A gas driving device is arranged inside the device body, and has an air intake port and an air exhaust port, and the air intake port is connected to the first cavity;

[0008] The cover plate is movably arranged on the equipment body, and has an open state and a closed state relative to the exhaust port. When the gas driving device is running, the cover plate is in the open state; when the gas driving device is stopped, the cover plate is in the closed state.

[0009] In an embodiment of the present application, the electronic device includes a device body, a gas driving device and a cover plate, the device body has a first cavity inside, and an air inlet is formed on the surface of the device body, the air inlet is connected to the first cavity, the gas driving device is arranged inside the device body, and the gas driving device has an air intake port and an exhaust port, the air intake port is connected to the first cavity, that is, the gas driving device can inhale air from the first cavity, so that the air outside the device body can enter the first cavity through the air inlet, and then be discharged through the exhaust port, and the heat in the electronic device can be taken away by the flow of air.

[0010] In addition, the cover can be movably arranged on the device body, and the cover can be moved to an open state and a closed state. When the cover is moved to the open state, the exhaust port is in an open state, and the airflow discharged by the gas drive device can be discharged to the outside of the electronic device to achieve heat dissipation. When the cover is moved to the closed state, external dust, liquid and other debris cannot enter the interior of the electronic device through the exhaust port.

[0011] Specifically, the cover is adjusted following the operation of the gas drive device. When the gas drive device is running, the cover is in an open state and the exhaust port is in an open state. At this time, the airflow generated by the gas drive device can be discharged to the outside of the electronic device through the exhaust port, thereby realizing active heat dissipation of the electronic device. When the gas drive device stops, the cover is in a closed state and the exhaust port is in a state of being sealed by the cover. At this time, the gas drive device does not generate airflow, thereby reducing the possibility of debris such as dust or liquid entering the interior of the electronic device through the exhaust port, reducing the chance of damage to the electronic device.

[0030] Combine the following Figures 1 to 11 An electronic device 100 according to an embodiment of the present application is described. Figure 1 and Figure 3 The arrows in the figure indicate the direction of air flow.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present application provides an electronic device 100, including: a device body 110, the device body 110 having a first cavity 112 and an air inlet 114, the first cavity 112 and the air inlet 114 being connected; a gas driving device 150, arranged inside the device body 110, the gas driving device 150 having an air intake port 152 and an air exhaust port 154, the air intake port 152 and the first cavity 112 being connected; a cover plate 160, movably arranged on the device body 110, the cover plate 160 has an open state and a closed state relative to the exhaust port 154, when the gas driving device 150 is running, the cover plate 160 is in an open state; when the gas driving device 150 is stopped, the cover plate 160 is in a closed state.

[0032] In an embodiment of the present application, the electronic device 100 includes a device body 110, a gas driving device 150 and a cover plate 160. The device body 110 has a first cavity 112 inside, and an air inlet 114 is formed on the surface of the device body 110, and the air inlet 114 is connected to the first cavity 112. The gas driving device 150 is arranged inside the device body 110, and the gas driving device 150 has an air intake port 152 and an exhaust port 154, and the air intake port 152 is connected to the first cavity 112, that is, the gas driving device 150 can inhale air from the first cavity 112, so that the air outside the device body 110 can enter the first cavity 112 through the air inlet 114, and then be discharged through the exhaust port 154. The flow of air can take away the heat in the electronic device 100.

[0033] In addition, the cover 160 can be movably disposed on the device body 110, and the cover 160 can be moved to an open state and a closed state. When the cover 160 is moved to the open state, the exhaust port 154 is in an open state, and the airflow exhausted by the gas drive device 150 can be discharged to the outside of the electronic device 100 to achieve heat dissipation. When the cover 160 is moved to the closed state, external debris such as dust or liquid cannot enter the interior of the electronic device 100 through the exhaust port 154.

[0034] Specifically, Figure 1 and Figure 3 As shown, the cover 160 is adjusted following the operation of the gas driving device 150. When the gas driving device 150 is running, the cover 160 is in an open state and the exhaust port 154 is in an open state. At this time, the airflow generated by the gas driving device 150 can be discharged to the outside of the electronic device 100 through the exhaust port 154, thereby realizing active heat dissipation of the electronic device 100.

[0035] like Figure 2 and Figure 4 As shown, when the gas driving device 150 stops, the cover 160 is in a closed state, and the exhaust port 154 is in a state of being sealed by the cover 160. At this time, the gas driving device 150 does not generate airflow, thereby reducing the possibility of dust, liquid and other debris entering the interior of the electronic device 100 through the exhaust port 154, reducing the chance of damage to the electronic device 100.

[0036] As described above, when the electronic device 100 is exhausting, the cover 160 is in a suspended state, and when the electronic device 100 is not exhausting, the cover 160 falls on the device body 110, thereby achieving the effect of hiding the airflow outlet.

[0037] The first cavity 112 may be located near the processor or the camera 146 of the device body 110 , thereby improving the heat dissipation effect.

[0038] like Figure 7 , Figure 8 and Fig. 9 As shown, as a possible implementation, the device body 110 includes a magnetic member 116, and the magnetic member 116 and the cover 160 are opposite to each other. At least a portion of the cover 160 is a magnetic conductive material or a magnetic material. When the gas driving device 150 is running, the airflow discharged from the exhaust port 154 puts the cover 160 in an open state; when the gas driving device 150 stops, the magnetic member 116 puts the cover 160 in a closed state.

[0039] Specifically, the device body 110 includes a magnetic component 116, and at least a portion of the cover 160 is made of magnetic conductive material or magnetic material. The magnetic component 116 and the cover 160 are arranged relative to each other, and when the gas driving device 150 stops, the magnetic component 116 adsorbs the cover 160, so that the cover 160 is in a closed state. When the gas driving device 150 is running, airflow is produced, and the pressure generated by the airflow is greater than the suction force of the magnetic component 116 on the cover 160, so that the cover 160 enters an open state.

[0040] That is, after the gas driving device 150 is running, the air pressure at the exhaust port 154 is increased, thereby offsetting the suction force of the magnetic member 116 on the cover 160, so that the cover 160 is away from the magnetic member 116 and is in an open state, and the gas driven by the gas driving device 150 can be discharged to the outside of the electronic device 100, thereby realizing active heat dissipation of the electronic device 100.

[0041] When the gas drive device 150 stops running, the air pressure at the exhaust port 154 is less than the suction force of the magnetic member 116 on the cover 160, and the suction force of the magnetic member 116 on the cover 160 cannot be offset. The magnetic member 116 sucks the cover 160 to achieve the effect of fixing the cover 160. The gas cannot push open the cover 160, so that the cover 160 is in a closed state, so that the cover 160 can play the role of closing the exhaust port 154, thereby reducing the possibility of dust, liquid and other debris entering the interior of the electronic device 100 and reducing the probability of damage to the electronic device 100.

[0042] The number of magnetic members 116 can be at least two, evenly distributed on the device body 110. The cover plate 160 is an appearance member at the airflow outlet, which can be magnetized or have magnetic materials embedded thereon, so that it can be opened by the airflow discharged by the gas drive device 150, and closed by adsorption of the magnetic members 116, thereby achieving the purpose of hiding the airflow outlet.

[0043] like Figures 1 to 9As shown, as a possible implementation, the cover 160 includes: a plate body 162; a guide post 164, which is disposed on the plate body 162, and the guide post 164 and the device body 110 are slidably connected.

[0044] Specifically, the cover 160 includes a plate body 162 and a guide post 164 . The guide post 164 is disposed on one side of the plate body 162 . The guide post 164 and the device body 110 are slidably connected, so that the guide post 164 ensures that the cover 160 can move stably.

[0045] Among them, the device body 110 has a guide hole, and the guide column 164 can be slidably arranged in the guide hole. The end of the guide column 164 has a limiting portion, and the limiting portion can be stuck on the edge of the guide hole, so that the guide column 164 is always inserted in the guide hole to prevent the cover plate 160 from separating from the device body 110.

[0046] As described above, through the guidance of the guide column 164, the airflow outlet presents a telescopic form. After the gas driving device 150 is turned on, the airflow blows the plate body 162 to float up, so that the cover 160 is in an open state, so that the airflow outlet is opened, and the airflow inside the electronic device 100 can be discharged from the inside of the electronic device 100. When the gas driving device 150 stops working, the cover 160 falls back to the closed state, and the magnetic member 116 attracts the plate body 162. The cover 160 is connected to the device body 110 through the guide column 164, and the movement direction of the cover 160 is controlled by the guide column 164. In addition, a limit portion can be set on the side of the guide column 164 away from the plate body 162 to prevent the cover 160 from separating from the device body 110.

[0047] The plate body 162 may be a circular plate or a polygonal plate.

[0048] like Figures 1 to 8 As shown, as a possible implementation, the device body 110 includes: a camera decoration component 118, a gas drive device 150 is arranged on the camera decoration component 118, and an air inlet 114 is arranged on the camera decoration component 118; a sealing cover 132, which is connected to the camera decoration component 118, and the sealing cover 132 and the camera decoration component 118 enclose a first cavity 112.

Usually, the position of the camera decoration component 118 corresponds to the camera 146 and the processor, and the camera 146 and the processor generate serious heat. Therefore, the gas drive device 150 is arranged on the camera decoration component 118, which can improve the heat dissipation effect of the camera 146 and the processor. In addition, the first cavity 112 is enclosed by the camera decoration component 118 and the sealing cover 132, which can reduce the difficulty of assembling the electronic device 100 and facilitate the installation of the gas drive device 150.

[0051] Specifically, the camera decoration assembly 118 includes a decorative ring 120 and a lens 130. The lens 130 is arranged on the decorative ring 120 to achieve light transmission to the camera 146. The decorative ring 120 includes an annular portion 122 and a mounting portion 128. The mounting portion 128 is located on the inner side of the annular portion 122. The gas drive device 150 is arranged on the mounting portion 128. The air inlet 114 is arranged on at least one of the decorative ring 120 and the lens 130 to ensure the circulation of airflow.

[0052] Furthermore, the gas driving device 150 and the mounting portion 128 may form a sealed connection, for example, the gas driving device 150 may be bonded to the mounting portion 128 by a sealant.

[0053] The mounting portion 128 and the sealing cover 132 are sealed and connected to form the first cavity 112 , thereby limiting the flow direction of the gas. The mounting portion 128 is also used to fix components such as the magnetic member 116 and the cover plate 160 . The guide column 164 is passed through the mounting portion 128 .

[0054] Among them, Figure 5 , Figure 6 and Figure 7 As shown, the air inlet 114 is located on the peripheral side of the decorative ring 120; or as shown in FIG. Fig.10 As shown, the air inlet 114 is located between the trim ring 120 and the lens 130 .

[0055] Specifically, Figure 5 , Figure 6 and Figure 7 As shown, the air inlet 114 is disposed on the circumferential side of the decoration ring 120 , thereby facilitating hiding of the air inlet 114 .

[0056] Or, if Fig.10 As shown, the lens 130 is disposed on the decorative ring 120, the lens 130 has an avoidance hole, the cover plate 160 is disposed in the avoidance hole, the lens 130 surrounds the circumference of the cover plate 160, and the air inlet 114 is located between the decorative ring 120 and the lens 130, that is, only the edges of the decorative ring 120 and the lens 130 need to be processed, thereby reducing the difficulty of producing the electronic device 100.

[0057] As described above, the gas drive device 150 is located inside the camera decorative assembly 118, and the air inlet is located at the edge of the decorative ring 120 of the camera 146, and a micro-gap structure is formed, which is not visually obvious, thereby facilitating the hiding of the air inlet.

[0058] The lens 130 is an appearance decoration part on the back of the device body 110, and it can be circular, polygonal or other shapes.

[0059] Of course, in other embodiments of the present application, the air inlet may be obtained by punching a hole in at least one of the lens 130 and the decorative ring 120 .

[0060] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, as a possible implementation, the annular portion 122 includes: a first ring body 124 , where the air inlet 114 is disposed; and a second ring body 126 , located on one side of the first ring body 124 , where the edge of the second ring body 126 protrudes from the first ring body 124 .

[0061] Specifically, the annular portion 122 includes a first ring body 124 and a second ring body 126. The first ring body 124 is located on one side of the second ring body 126, and the edge of the second ring body 126 protrudes from the first ring body 124, that is, the diameter of the second ring body 126 is larger than the diameter of the first ring body 124. The air inlet 114 is arranged on the first ring body 124, so that the first ring body 124 is shielded by the second ring body 126, and the air inlet 114 is shielded, thereby hiding the air inlet 114 and reducing the possibility of dust, liquid and other debris entering the air inlet 114.

[0062] The edge of the first ring body 124 may be circular or polygonal, and the edge of the second ring body 126 may be circular or polygonal.

[0063] like Figure 5 and Figure 6As shown, as a possible embodiment, the device body 110 also includes: a shell 142, the shell 142 has a first through hole 144, the first ring body 124 is arranged in the first through hole 144, the shell 142 and the first ring body 124 are connected, and at least part of the air inlet 114 is located between the second ring body 126 and the shell 142.

[0064] Specifically, the device body 110 also includes a shell 142, and the camera decoration component 118 is arranged on the shell 142. The shell 142 has a first through hole 144, and the first ring body 124 is arranged in the first through hole 144, thereby realizing the installation of the two. The shell 142 and the first ring body 124 are connected, and at least part of the air inlet 114 is located between the second ring body 126 and the shell 142, thereby ensuring that the air inlet 114 can smoothly inhale airflow and improve the heat dissipation effect of the electronic device 100.

[0065] like Figure 8 , Fig. 9 and Fig.11 As shown in FIG. 1 , as a possible implementation, the camera decoration assembly 118 has a second through hole 136, the gas driving device 150 has an exhaust portion 156, the exhaust port 154 is disposed on the exhaust portion 156, and at least a portion of the exhaust portion 156 is embedded in the second through hole 136; wherein, as Figures 3 to 6 As shown, the electronic device 100 further includes a seal 148 , which is disposed between the camera decoration assembly 118 and the gas driving device 150 , and the seal 148 is disposed around the exhaust portion 156 .

[0066] Specifically, Figure 8 , Fig. 9 and Fig.11 As shown, the camera decoration component 118 has a second through hole 136, the gas drive device 150 has an exhaust portion 156, the exhaust port 154 is arranged on the exhaust portion 156, and the exhaust portion 156 is embedded in the second through hole 136, so that the airflow discharged from the exhaust port 154 can directly impact the cover plate 160, making the cover plate 160 easier to open.

[0067] And, if Figures 3 to 6 As shown, the electronic device 100 also includes a seal 148, which is disposed between the camera decoration assembly 118 and the gas drive device 150. The seal 148 is disposed around the exhaust portion 156, thereby sealing the gas drive device 150 and the camera decoration assembly 118, reducing the possibility of leakage of the airflow discharged from the exhaust port 154, and ensuring that the cover 160 can be opened smoothly.

[0069] Specifically, the sealing cover 132 has a groove 134, and part of the gas driving device 150 is located in the groove 134. That is, the local groove 134 of the sealing cover 132 is used to accommodate the gas driving device 150, thereby reducing the volume of the first cavity 112 and reducing the encroachment of the first cavity 112 on the internal space of the device body 110, thereby facilitating the arrangement of internal components of the electronic device 100.

[0070] The sealing cover 132 may be attached to a processor, a battery or other components of the electronic device 100 to improve the heat dissipation effect.

[0074] Specifically, the gas driving device 150 includes at least one of a piezoelectric pump, a gear pump, and a centrifugal pump.

It has the characteristics of small size, high flow rate, and high wind pressure, so as to bring better heat dissipation effect to the electronic device 100. In addition, through the design of the air duct structure, the air inlet and the air flow outlet are hidden, thereby reducing the possibility of dust or liquid and other debris entering the interior of the electronic device 100, wherein the air flow outlet is opened when the piezoelectric pump is working and closed when the piezoelectric pump is not working.
