Description

Technical Field

[0001] The present application relates to the technical field of temperature detection of foldable electronic devices, and in particular to a foldable electronic device and a housing assembly thereof. Background Art

[0002] At present, the mainstream temperature measurement scheme for electronic devices such as mobile phones is to measure the temperature through a thermistor, and then obtain the ambient temperature through fitting of multiple thermistors. Currently, mobile phones mainly use NTC resistors to measure temperature.

[0003] NTC is the abbreviation of Negative Temperature Coefficient, which means negative temperature coefficient. It generally refers to semiconductor materials or components with large negative temperature coefficient. Usually, the NTC we mention refers to negative temperature coefficient thermistor, referred to as NTC thermistor. Also known as negative temperature coefficient thermistor, it is a type of sensor resistor whose resistance value decreases as the temperature increases. NTC thermistor is a very simple temperature sensor, which is very common in consumer electronic products. NTC thermistor is a typical temperature-sensitive semiconductor resistor, and its resistance value decreases in a step-like manner as the temperature increases. NTC thermistor is made of metal oxides such as manganese, cobalt, nickel and copper as the main materials, and is made using ceramic technology. These metal oxide materials all have semiconductor properties because they are completely similar to semiconductor materials such as germanium and silicon in terms of conductivity. When the temperature is low, the number of carriers (electrons and holes) of these oxide materials is small, so their resistance value is high; as the temperature increases, the number of carriers increases, so the resistance value decreases.

[0004] The conventional technical solution of using NTC resistors to measure temperature has the following main problems. First, the NTC thermistor is affected by the heat generated by internal devices, which requires complex function fitting and has certain errors. In addition, the measured temperature is located inside the whole machine, and multiple NTCs are required to cooperate in shell temperature fitting to obtain the ambient temperature. The design is complex and difficult, and a large number of NTCs are required to perform temperature tests and obtain the ambient temperature through fitting. This method of measuring ambient temperature is affected by internal heating devices and is not in direct contact with the external environment, so there are certain errors. Summary of the invention

[0005] A first aspect of an embodiment of the present application provides a housing assembly, the housing assembly comprising a first support plate, a second support plate, a rotating shaft, a rotating shaft protection plate, and a deformation detection sensor;

[0006] The first support plate and the second support plate are fixedly connected to opposite sides of the rotating shaft respectively, and the first support plate and the second support plate can be rotated under the drive of the rotating shaft to switch between a folded state and an unfolded state; the rotating shaft protection plate is provided on the rotating shaft, and the rotating shaft protection plate is used to protect the outer side of the rotating shaft when the first support plate and the second support plate are in a relatively folded state;

[0007] The deformation detection sensor is arranged on the rotating shaft protection plate and is used to detect the deformation amount of the rotating shaft protection plate, and judge the ambient temperature of the position where the shell component is located based on the deformation amount.

[0008] In a second aspect, an embodiment of the present application provides a foldable electronic device, which includes a flexible display and the shell assembly described in the above embodiment; the flexible display is connected to a first support plate and a second support plate of the shell assembly, and can switch between a folded state and an unfolded state along with the first support plate and the second support plate.

[0009] The shell assembly provided in the embodiment of the present application utilizes a deformation detection sensor to detect the deformation of the hinge protection plate, and determines the ambient temperature of the location of the shell assembly based on the deformation. The temperature sensing component (hinge protection plate) of this structure is in direct contact with the external environment, and the measurement of the ambient temperature is convenient and accurate.

[0023] The present application embodiment provides a foldable electronic device. The electronic device in the present application embodiment may include a mobile phone, a tablet computer, a laptop computer, a wearable device, and other electronic devices with a folding function. This embodiment only takes a foldable mobile phone as an example for explanation. Figures 1 to 5 , Figure 1 is a schematic diagram of a folded state of an embodiment of an electronic device of the present application, Figure 2 yes Figure 1 A schematic diagram of the structure of the electronic device in the embodiment in the open state, Figure 3 yes Figure 1 A schematic cross-sectional view of the structure of the electronic device at AA in the embodiment, Figure 4 yes Figure 2 A schematic cross-sectional view of the structure of the electronic device at position BB in the embodiment, Figure 5 yes Figure 2 Schematic diagram of the structural disassembly of the electronic device in the embodiment; the electronic device in this embodiment includes a housing assembly 10 , a flexible display screen 20 and a support sheet 30 .

[0024] Specifically, the housing assembly 10 includes a first support plate 11, a second support plate 12, a rotating shaft 13, a rotating shaft protection plate 14, and a deformation detection sensor 15. The first support plate 11 and the second support plate 12 are respectively fixedly connected to opposite sides of the rotating shaft 13, and the first support plate 11 and the second support plate 12 can be rotated under the drive of the rotating shaft 13 to be in a folded state ( Figure 1 medium state) and expanded state ( Figure 2 The middle state, where Figure 4 The direction of the middle arrow indicates the relative folding and rotating direction of the first support plate 11 and the second support plate 12). The flexible display screen 20 is connected to the first support plate 11 and the second support plate 12 of the housing assembly 10, and can be switched between the folded state and the unfolded state along with the first support plate 11 and the second support plate 12. Among them, the rotating shaft 13 may include a gear set and other structures, and the detailed features of this part are within the scope of understanding of those skilled in the art and will not be repeated here.

[0025] Please also read Figure 6 , Figure 6 It is a schematic cross-sectional view of the local structure of an embodiment of the electronic device of the present application, wherein a shaft protection plate 14 is provided on the shaft 13, and the shaft protection plate 14 is used to protect the outer side of the shaft 13 when the first support plate 11 and the second support plate 12 are in a relatively folded state.

[0026] Optionally, the deformation detection sensor 15 is provided on the shaft protection plate 14 and is used to detect the deformation of the shaft protection plate 14 and determine the ambient temperature of the location of the housing assembly 10 based on the deformation. The deformation detection sensor 15 can be directly or indirectly fixed on the shaft protection plate 14, and the specific connection form is not specifically limited here.

[0027] Please also read Figure 7 , Figure 7 yes Figure 6 Schematic diagram of the structure of the deformation detection sensor and the shaft protection plate in the embodiment. Optionally, the shaft protection plate 14 in the present embodiment includes a first material plate 141 and a second material plate 142 which are stacked. The thermal deformation coefficients of the first material plate 141 and the second material plate 142 are different, that is, when the first material plate 141 and the second material plate 142 are in the same temperature environment at the same time, the thermal deformation amounts of the two are different. The first material plate 141 and the second material plate 142 are tightly attached together. When the ambient temperature changes, due to the different thermal expansion coefficients, the lengths of the two are different, so that the shaft protection plate 14 is deformed toward one side, such as Figure 7The middle dotted line indicates that the thermal deformation of the shaft protection plate 14 (the first material plate 141 and the second material plate 142) is positively correlated with the temperature. The higher the temperature, the greater the deformation. The corresponding temperature change can be obtained by measuring the deformation with a deformation detection sensor.

[0028] Optionally, the materials of the first material plate 141 and the second material plate 142 in the embodiment of the present application can be two metal plates with different thermal deformation coefficients, which can be specifically selected from any one of aluminum, copper, iron, nickel, platinum, titanium and their alloys, such as a combination of copper plate and iron plate, a combination of aluminum alloy plate and copper alloy plate, a combination of nickel plate and stainless steel plate, etc. As long as the shaft protection plate 14 is formed by two layers of metal plates of different materials, they will not be listed one by one here.

[0029] Optionally, see Figure 5 The support sheet 30 in this embodiment is disposed between the flexible display screen 20 and the shell assembly 10 to support and protect the flexible display screen 20 .

[0030] Optionally, the support sheet 30 may include a first support portion 31, a second support portion 32 and a bending portion 33, wherein the first support portion 31 and the second support portion 32 are respectively connected to opposite sides of the bending portion 33, and transition connection areas 34 are respectively provided on opposite sides where the bending portion 33 is connected to the first support portion 31 and the second support portion 32, wherein the transition connection area 34 is provided with a hollow structure to facilitate the bending of the overall structure of the support sheet 30.

[0031] Optionally, the support sheet 30 in this embodiment can be made of stainless steel, carbon fiber or composite materials, or can be made of a plate formed by stacking the above materials. Optionally, the bending strength of the bending portion 33 in this embodiment is less than the bending strength of the first support portion 31 and the second support portion 32, so that the bending portion 33 is easier to bend than the first support portion 31 and the second support portion 32, while ensuring the supporting strength of the first support portion 31 and the second support portion 32 to the flexible display screen 20. Among them, the way in which the bending strength of the bending portion 33 is less than the bending strength of the first support portion 31 and the second support portion 32 can include designing the bending portion 33 to be thinner than the first support portion 31 and the second support portion 32, or the bending portion 33 is made of a material with lower bending strength.

[0032] Also, please continue to read Figure 3 and Figure 4The electronic device in the embodiment of the present application also includes a battery 40, a control circuit board 50, and devices such as speakers, cameras, and sensors.
