Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

With the continuous development of technologies, the performance of electronic devices (such as mobile phones, tablet computers, and the like) is more and more excellent. However, the heat generated by the electronic device is relatively high, and if the heat is not timely derived, the heat is not only generated and burnt by the electronic device, which affects normal use of the user, but also may cause adverse effects (such as overheating and frequency reduction of the central processing unit, and reduction of the service life) on each component in operation, and may cause spontaneous combustion and even explosion of the electronic device. Therefore, heat dissipation is a big problem that must be solved in the development process of electronic devices.

In view of the above technical problems, the present application provides an electronic device 100, which aims to provide an air-cooling heat dissipation manner for the electronic device 100 to achieve effective heat dissipation of the electronic device 100.

It is understood that the electronic device 100 may be, but is not limited to, a mobile phone, a tablet computer, a Personal Digital Assistant (PDA), an e-book reader, an MP3 (motion Picture Experts Group Audio Layer III) player, an MP4 (motion Picture Experts Group Audio Layer IV) player, a wearable device, a navigator, a handheld game console, etc.

The following describes a specific structure of the electronic device 100 in a specific embodiment, and takes the electronic device 100 as an example of a horizontal position:

as shown in fig. 1 and fig. 2, in an embodiment of the electronic device 100 of the present application, the electronic device 100 includes a housing 10 and a card holder 20, an outer wall surface of the housing 10 is provided with a card slot 11 communicating with an inner space of the housing 10, the card holder 20 is inserted into the card slot 11, a portion of the card holder 20 located in the housing 10 is provided with a first mounting position 231 and a second mounting position 211 spaced from each other, the second mounting position 211 is used for mounting a function card, and the card holder 20 is provided with an air outlet 20a communicating with an outer space of the housing 10 and the inner space of the housing 10; the electronic device 100 further includes a fan 30, and the fan 30 is mounted at the first mounting position 231 and used for guiding the airflow in the housing 10 to be discharged through the air outlet 20 a.

It can be understood that, in the technical solution of the present embodiment, when the fan 30 is operated, the air flow in the casing 10 flows to the fan 30 due to the guidance of the fan 30, and is exhausted from the air outlet 20a on the casing 10 after passing through the fan 30, so that the air flow absorbing heat in the casing 10 is continuously exhausted out of the casing 10; at the same time, the cold air outside the casing 10 is continuously supplied into the casing 10 to absorb the heat in the casing 10. By circulating in this way, convection heat transfer is realized inside the electronic device 100, and the heat dissipation capability of the electronic device 100 is enhanced. That is, the technical solution of this embodiment provides an air-cooling heat dissipation method for the electronic device 100, and realizes effective heat dissipation of the electronic device 100.

Moreover, because the fan 30 is integrated on the card holder 20, a supporting structure and related parts (such as a fan 30 bracket and a fixing screw) required for mounting the fan 30 can be effectively reduced, so that the number of detached parts of the electronic device 100 is reduced, the internal structure of the electronic device 100 is simplified, and the convenience in detaching and mounting the electronic device 100 is improved. Meanwhile, the reduction of the number of the disassembled parts is also beneficial to controlling the accumulated tolerance of assembly and reducing the structural clearance, thereby being beneficial to the water resistance and dust resistance of the electronic equipment 100; and, it is also advantageous to save the internal space of the electronic device 100 and to control the production cost.

Moreover, because the fan 30 is integrated on the card holder 20, the fan 30 can be closer to the air outlet 20a, thereby being beneficial to discharging hot air and improving the heat dissipation efficiency.

It should be noted that the function card may be a subscriber identity module card (e.g., a SIM card, a Micro-SIM card, a Nano-SIM card, etc.), or may be a memory card (e.g., an SD card, a Micro-SD card, etc.). Of course, other function cards are also possible. Those skilled in the art can make a reasonable selection according to the actual application scenario, and details are not repeated here.

The first mounting position 231 may be a planar region or a groove (specifically, the groove may also be configured in a form of a contour groove). And, when fan 30 installed in first installation position 231, fan 30 both can be fixed through detachable modes such as screw connection, buckle connection, pin junction, also can be fixed through non-detachable modes such as gluing, riveting, welding, and the like, and technical personnel in the art can rationally select according to practical application scene, and no longer give unnecessary details one by one here. It can be understood that, when the fan 30 is fixed on the card holder 20 in a detachable manner, the fan 30 can be flexibly disassembled and assembled along with the disassembling and assembling process of the card holder 20, so that the cleaning, maintenance, replacement and other operations of the fan 30 are facilitated, and the cleaning of the air duct is facilitated.

The second mounting location 211 is generally configured as a contour groove, and the function card is laid on the bottom wall of the contour groove and is engaged with the side wall of the contour groove to realize fixation. Specifically, the surface to be identified of the function card may be disposed facing the bottom wall of the pseudo-groove, and is contacted with the card reading device in the electronic device 100 through an avoidance port formed on the bottom wall of the pseudo-groove, so as to be identified; the surface of the function card to be identified may also be arranged opposite to the bottom wall of the contour groove, and is contacted with the card reading device in the electronic device 100 through the notch of the contour groove, so as to be identified.

The card holder 20 may be formed by CNC machining a metal material (e.g., an aluminum alloy) or by integral injection molding.

The fan 30 may be a centrifugal fan 30, a cross flow fan 30, an axial flow fan 30, or the like. In addition, the power supply for supplying power to the fan 30 may be integrated with the fan 30 on the card holder 20, may be a battery of the electronic device 100, or may be an external power supply. The fan blades of the fan 30 and the shell 10 can be obtained by injection molding of liquid crystal high molecular polymer, so that the effects of low thickness and high strength are achieved.

It is understood that the cool air outside the casing 10 can flow into the casing 10 through the assembly gap of the electronic device 100, and can also flow into the casing 10 through the air inlet holes 13 specially formed on the casing 10. The air outlet 20a and the pin inserting hole may be two independent through holes or share the same through hole. When the air outlet 20a and the pin holes share the same through hole, the fan 30 can avoid the insertion path of the pins to some extent in the setting, so as to avoid the influence of the insertion of the pins on the fan 30. For example: configuring the normal direction of the plane where the air outlet of the fan 30 is located along the air outlet direction to point to the air outlet hole 20a and form an included angle with the insertion path of the contact pin; or, the air outlet of the fan 30 is not disposed toward the air outlet 20a, but some auxiliary air ducts are disposed to guide the airflow blown out from the air outlet to the air outlet 20 a; or other effective and reasonable form. When the air outlet 20a and the pin inserting hole share the same through hole, the number of the holes formed in the whole electronic device 100 is smaller, and the integrity is better.

When the air outlet 20a and the pin inserting hole are two independent through holes, there may be corresponding arrangements, for example: the support card 20 comprises an end cover and a body, wherein the end cover is accommodated in the clamping groove 11 and is used for plugging the clamping groove 11 so as to enhance the integrity of the machine body; at this time, the end cap has an outer surface and an inner surface which are oppositely arranged, and the body is convexly arranged on the inner surface of the end cap and extends towards the inner space of the shell 10; the upper surface of end cover is higher than the upper surface of body, and the exhaust vent 20a of intercommunication end cover inside and outside surface is seted up to the part of end cover that exceeds the body upper surface, and first installation position 231 and second installation position 211 all set up on the upper surface of body. At this time, the blower may be installed on the first installation site 231, and the outlet is disposed toward the outlet hole 20 a. Meanwhile, the end part of the end cover, which exceeds the side edge of the body in the horizontal direction, is provided with a pin hole which is communicated with the inner surface and the outer surface of the end cover for inserting a pin so as to take out the card holder.

Of course, those skilled in the art can also perform other reasonable and effective configurations for the air outlet 20a, the fan 30, and the first installation position 231 according to the actual situation, and the details are not repeated herein.

The first installation position 231 is taken as an installation groove for example, and the following description is given:

as shown in fig. 1 and 2, the first mounting portion 231 is a mounting groove, the fan 30 is accommodated in the mounting groove, the air outlet 20a is communicated with the mounting groove, and the fan 30 is used for guiding the airflow in the housing 10 to enter the fan 30 from the notch of the mounting groove, and to pass through the fan 30 and be discharged from the air outlet 20 a.

In this embodiment, be formed with the air-out wind channel between the notch of mounting groove and exhaust vent 20a, fan 30 sets up in this air-out wind channel, and fan 30's air intake sets up with the notch intercommunication of mounting groove, and fan 30's air outlet and exhaust vent 20a intercommunication set up. Thus, when the fan 30 is operated, the air flow in the casing 10 can be introduced into the air outlet duct from the notch of the mounting groove, and the air flow in the air outlet duct is accelerated by the fan 30 and then discharged from the air outlet hole 20 a.

It can be understood that the arrangement that the fan 30 is accommodated in the mounting groove can protect the fan 30, and prevent the fan 30 from being damaged due to extrusion and collision with the shell 10 when the fan 30 is disassembled and assembled together with the bracket.

Based on the aforesaid fan 30 accepts the setting in the mounting groove, this application has still made reasonable layout to the circuit switch-on relation of fan 30, specifically as shown in fig. 1 and fig. 2:

an avoiding through hole 20b is formed in the bottom wall of the mounting groove, the fan 30 is provided with an electric connection end 31, and the electric connection end 31 faces the avoiding through hole 20b and is used for being conducted with a power supply of the electronic equipment 100.

At this time, since the electrifying end 31 of the fan 30 is disposed toward the avoiding through hole 20b, the relevant structure in the housing 10 for cooperating with the electrifying end 31 can be directly associated with the electrifying end 31 through the avoiding through hole 20b, thereby conducting the fan 30 with the power supply. Therefore, the structure is simple, and the assembly is convenient. Specifically, the electrical connection terminal 31 of the fan 30 may include two terminals for respectively leading in and leading out current; the terminals may be conductive pads, conductive posts, conductive clips 60, etc.

Further, in order to be connected (i.e. conducted) with the electric connection terminal 31 of the fan 30, the present application also makes the following design for the relevant structure inside the housing 10 for matching with the electric connection terminal 31, as specifically shown in fig. 1 and 2:

Specifically, two conductive elastic sheets 60 on the circuit board 50 may be provided, and are respectively used for leading out current and leading in current; at this time, the two conductive elastic pieces 60 on the circuit board 50 are respectively abutted against the two terminals of the electric connection terminal 31 to conduct the fan 30 with the circuit board 50, so that the fan 30 can be conducted with the power supply through the circuit board 50.

It can be understood that the fan 30 can be conducted with the circuit board 50 by using the circuit board 50 and the conductive elastic sheet 60 thereon. Then, the fan 30 can be conducted with the power supply by utilizing the conducting relationship between the circuit board 50 and the power supply. The circuit board 50 is a common component in the electronic device 100, and the assembly of the conductive elastic sheet 60 thereon is also quite simple. In this way, the relative structure of the housing 10 for mating with the electrical terminals 31 is simplified, and the assembly process is facilitated. Moreover, the elasticity of the conductive elastic sheet 60 can also improve the connection stability. In addition, in order to facilitate the conductive elastic sheet 60 to smoothly slide into the avoiding through hole 20b and abut against the electric connection terminal 31 in the moving-in process of the fan 30, and to facilitate the conductive elastic sheet 60 to smoothly slide out of the avoiding through hole 20b and separate from the electric connection terminal 31 in the moving-out process of the fan 30, one end of the conductive elastic sheet 60, which is deviated from the circuit board 50, is provided with a guide surface (both an arc surface and a plane surface) in the moving-in direction of the card holder 20 and the moving-out direction of the card holder 20.

Of course, it can be understood that the conductive elastic sheet 60 may also be replaced by other reasonable and effective structures such as a thimble connector, and those skilled in the art may perform reasonable configuration according to the actual application scenario, and details are not described herein.

at this time, the bottom support 23 slides relative to the bearing plate 21 and has an initial position, a machine detaching position and a card detaching position, when the bottom support 23 is located at the initial position, the notch of the mounting groove is arranged opposite to the lower end opening of the top channel 20c, and the top channel 20c communicates the mounting groove with one side of the bearing plate 21, which is back to the bottom support 23; when the bottom support 23 is located at the dismounting position, the mounting groove is located outside the opening of the clamping groove 11 on the outer wall surface of the shell 10, and at the moment, the fan 30 is exposed; when the bottom support 23 is located at the detaching position, the second mounting position 211 is located outside the opening of the card slot 11 on the outer surface of the housing 10, and at this time, the function card is exposed.

It will be appreciated that, with the above-described design, the function card can be mounted on the carrier plate 21, and the fan 30 can be mounted on the bottom bracket 23, and relative sliding can also occur between the carrier plate 21 and the bottom bracket 23. Thus, when the card holder 20 with the function card and the fan 30 mounted thereon is inserted into the card slot 11 of the housing 10, the fan 30 can extend outwards along with the outward sliding of the bottom support 23 relative to the bearing plate 21, so that the fan 30 can move outwards independently of the function card, thereby facilitating the related processing (such as cleaning, maintenance, replacement, etc.) of the fan 30. At this time, the function card does not need to be moved out together, and the function card can continue to execute the function thereof, so that inconvenience caused by stopping using the function card when the fan 30 needs to perform related processing is avoided, and convenience in use of the electronic device 100 is improved.

In addition, in the air path aspect, the air outlet 20a is communicated with the side wall of the mounting groove, which is back to the clamping groove 11. At this time, the air flow in the housing 10 flows in from the upper end opening of the top passage 20c under the guide of the fan 30, passes through the top passage 20c, and is discharged from the air outlet 20a through the notch of the mounting groove and the fan 30.

In order to prevent the first driving mechanism 70 and the second driving mechanism 80 from interfering with each other, the first driving mechanism 70 and the second driving mechanism 80 may be disposed on both sides of the insertion direction of the card holder 20. Further, it is understood that both the first drive mechanism 70 and the second drive mechanism 80 may be mounted on the housing 10.
