Technical Field

Background

With the gradual maturity of flexible screen technology, mobile phones adopting a folding screen design are gradually appearing, and the folding screen mobile phones mean that the screen can be folded inwards or outwards, so that the screen of the mobile phone can be converted between a smaller size state and a larger size state.

However, the folding screen becomes fragile at low temperature, and some manufacturers can specially say that the mobile phone does not need to be bent at minus 5 ℃ and lower when the mobile phone leaves a factory, so as to prevent the screen from being accidentally damaged in cold weather. To address this problem, current solutions may be to generate heat by lighting pixels that fold the curved portion of the screen, or to use resistive heating elements for screen heating. However, these heating methods have the disadvantage of low electric-heat conversion efficiency, and the folding screen cannot be flexibly bent at low temperature, and the energy consumption of the folding screen mobile phone is further increased.

Detailed Description

To make the objects, technical solutions and advantages of the present disclosure more apparent, the following embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings. It is to be understood that the described embodiments are merely a subset of the disclosed embodiments and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

Technical solutions disclosed in the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present disclosure provides an electronic device, including:

the device comprises a device body, a screen 1, a sound production device 2, a heat conduction component 3 and a power supply component 4.

The screen 1 is arranged on the device main body, the screen comprises a first screen 102, a second screen 103 and a bending part 101, the first screen 102 and the second screen 103 are connected in a foldable manner through the bending part 101, the first screen 102, the second screen 103 and the device main body surround to form an accommodating space, and the power supply assembly 4, the sound generating device 2 and the heat conducting assembly 3 are all arranged in the accommodating space; the sound generating device 2 comprises a coil component 201, one end of the heat conducting component 3 is connected with the sound generating device 2, the other end of the heat conducting component 3 extends to the bending part 101, and the power supply component 4 is electrically connected with the coil component 201.

When the coil assembly 201 is energized, heat generated by the coil assembly 201 can be transferred to the bent portion 101, and the heat generated by the coil assembly 201 can provide temperature compensation for the bent portion 101.

The folded screens of conventional electronic devices are screen heated at the fold primarily by resistive heating elements. However, the heating mode has the defect of low electric-heat conversion efficiency, the folding screen cannot be flexibly bent at a low temperature, and the energy consumption of the folding screen mobile phone is increased. The electronic equipment provided by the embodiment of the disclosure utilizes the original coil assembly 201 in the sound generating device 2, when the temperature of the bending part 101 is too low, the bending part 101 can be efficiently heated by transferring the heat generated by the coil assembly 201 in the power-on process to the bending part 101, so that the flexibility and reliability of the bending part 101 at low temperature are ensured, and meanwhile, the internal structure of the electronic equipment is simplified, and more utilization space is provided for the electronic equipment.

Alternatively, one end of the heat conductive member 3 may be connected to the coil member 201.

Specifically, since the coil assembly 201 generates a large amount of heat when being energized, the coil assembly 201 serves as a main body for generating heat, and the direct connection of the heat conducting assembly 3 to the coil assembly 201 can quickly and efficiently transfer the heat generated by the coil assembly 201 to the bent portion 101 for providing temperature compensation for the bent portion 101. However, since the coil assembly 201 interacts with the magnetic assembly in the sound generating device 2 to generate vibration when the coil assembly 201 is powered on, in order to avoid the influence of the direct connection of the heat conducting assembly 3 to the coil assembly 201 on the vibration of the coil assembly 201, one end of the heat conducting assembly 3 may also be connected to the casing or the frame of the sound generating device 2.

Optionally, the electronic device further includes a control component and a temperature detection component connected to the control component, the control component is electrically connected to the power supply component 4 and can control an on-off state of the power supply component 4, and the temperature detection component is disposed near the bending portion 101 and is configured to detect a temperature of the bending portion 101 in real time;

when the temperature detected by the temperature detection component is lower than the low-temperature threshold, the control component controls the power supply component 4 to start, the power supply component 4 energizes the coil component 201, and then the heat generated by the coil component 201 in the energizing process is transferred to the bent part 101, so that the bent part 101 can be heated; under the condition that the temperature detected by the temperature detection component is higher than the high-temperature threshold value, the control component controls the power supply component 4 to stop, the coil component 201 is disconnected from the power supply component 4, and the bent part 101 can be kept at the temperature of flexible bending, so that the temperature of the bent part 101 can be efficiently controlled. The current supplied to the coil unit 201 by the power supply unit 4 may be either direct current or alternating current. When the power supply module 4 outputs alternating current, the power supply module 4 includes a direct current power supply and an inverter.

Optionally, the value range of the low temperature threshold is 5-8 ℃, and the value range of the high temperature threshold is 30-35 ℃.

Specifically, the temperature control range of the bending part 101 is generally 5-35 ℃, and the bending part 101 can be flexibly bent under the condition of being 5-35 ℃, and has high bending stability. In order to ensure that the heating temperature of the coil assembly 201 on the bent portion 101 is not lower than 5 ℃, the bent portion 101 needs to be heated in time when the temperature of the bent portion 101 is about to be lower than 5 ℃, that is, lower than a low-temperature threshold, and the value range of the low-temperature threshold of 5-8 ℃ just can meet the heating requirement on the bent portion 101; similarly, in order to prevent the heating temperature of the coil component 201 on the bending portion 101 from being too high, the current of the coil component 201 needs to be cut off immediately when the temperature of the bending portion 101 is about to be higher than 35 ℃, that is, higher than a high temperature threshold, and the value range of the high temperature threshold of 30-35 ℃ can also ensure the heating requirement of the bending portion 101.

Optionally, the control component is a CPU.

Specifically, the CPU may be a CPU of the electronic device, and the CPU may control the on/off and the current of the power supply module 4 by using the characteristics of low power consumption, high integration, and high processing speed, so as to flexibly control the heating efficiency of the coil module 201.

Optionally, the power supply assembly 4 is arranged in the sound emitting device 2, and the power supply assembly 4 comprises a power amplifier.

Specifically, the power amplifier has the characteristics of small size, high efficiency and high output power, and the output power can be flexibly adjusted. The power amplifier can provide continuous current for the coil assembly 201 on the basis of ensuring the good sounding quality of the sounding device 2, and the power amplifier has a large current regulation range and high regulation efficiency. In addition, the power supply module 4 may be a battery in the device body, and the battery may provide power to the electronic device and may provide a stable current to the coil module 201.

Optionally, the voltage output of the power supply component 4 ranges from 0V to 3.8V.

In a specific implementation mode, the electronic device may be a folding screen mobile phone, and the impedance of a sound generating device on the mobile phone is generally about 7 Ω, and the highest temperature that can be borne is 100 ℃. When the voltage lower than 3.8V is applied to the coil of the mobile phone sounding device, the temperature of the sounding device can be ensured to be not higher than 80 ℃ and far lower than the highest temperature of 100 ℃. Therefore, the bending part of the screen can be heated by the coil while the safety and the service life of the sound generating device are ensured.

Optionally, referring to fig. 1, the bending part 101 is disposed in the middle of the screen 1, and the first screen 102 and the second screen 103 are disposed symmetrically with respect to the bending part 101.

In particular, since some components that cannot be folded, such as a battery and a motherboard, must be inevitably assembled in the electronic device, it is necessary to leave a large space for the screen 1 to be folded, so as to dispose the components that cannot be folded. In the embodiment of the present disclosure, the bending portion 101 is disposed in the middle of the screen 1, so that the screen 1 can be folded in half in a manner similar to a book, and a sufficient extending space is reserved for the screen 1 on both sides of the bending portion 101, and the electronic device can be folded in a smaller folding state along the bending portion 101, so that the occupied space after folding is greatly reduced.

Optionally, the heat conducting component 3 is made of a copper pipe.

Specifically, the heat conducting assembly 3 is arranged to transfer heat generated by the coil assembly 201 during the power-on process to the bending portion 101, so as to efficiently heat the bending portion 101, and also to quickly transfer excess heat inside the electronic device to the bending portion 101, so as to release the heat inside the electronic device while ensuring the temperature compensation of the bending portion 101. The copper pipe not only has the characteristics of light weight, good heat conductivity and high low-temperature strength, and can play a good role in heat transfer, but also is convenient to connect with the coil assembly 201, and plays a role in enhancing the internal structure compactness of the electronic equipment.

Optionally, referring to fig. 1, the heat conducting assembly 3 includes a first heat conducting section and a second heat conducting section, one end of the first heat conducting section is connected to the coil assembly 201, the other end of the first heat conducting section is connected to the second heat conducting section, and the second heat conducting section is disposed on the bending portion 101.

Specifically, the function of the heat conducting assembly 3 may include two stages, the first stage is to transfer heat generated by the coil assembly 201 during the power-on process to the vicinity of the bent portion 101, and the second stage is to efficiently transfer the transferred heat to the bent portion 101 to heat the bent portion 101. The first heat conducting section can rapidly transfer heat generated by the coil assembly 201 to the bending part 101, and the second heat conducting section can be arranged along the bending part 101, that is, has more areas close to or in contact with the bending part 101, so that the heat can be efficiently transferred to the bending part 101, the bending part 101 is rapidly heated, and the purpose of efficiently adjusting the temperature of the bending part 101 is achieved.

Optionally, the electronic device may include, but is not limited to, at least one of: smart watches, cell phones, tablet computers, e-book readers, MP3 players, MP4 players, computers, set-top boxes, smart televisions, wearable devices, and the like.

While the present disclosure has been described with reference to the embodiments illustrated in the drawings, which are intended to be illustrative rather than restrictive, it will be apparent to those of ordinary skill in the art in light of the present disclosure that many more modifications may be made without departing from the spirit of the disclosure and the scope of the appended claims.
