Description

Technical Field

[0001] The present invention belongs to the technical field related to mobile phone performance testing, and more specifically, particularly relates to a mobile phone thermal experience testing device and a mobile phone thermal experience testing method. Background Art

[0002] The mobile phone thermal experience test device is a test device used to simulate the heating of a real mobile phone. The shape of the mobile phone thermal experience test device is similar to the appearance of conventional mobile phones on the market (using a rectangular flat structure), and is suitable for conventional mobile phone usage (using vertical hand holding) and the range of contact with hand skin.

[0003] In actual situations, in addition to conventional vertical hand operation, mobile phones can also be held horizontally. In addition to contact with human hand skin, there are also cases of contact with human face and ears. Moreover, because different people have different contact methods, the degree of grip is also different, which will affect the user's thermal perception due to the tightness of the grip. The mobile phone thermal experience test device is used to test the human body temperature threshold under different contact forms, and then guide the design of the heat source layout of mobile phones under different contact postures.

[0004] For thermal experience test devices, the two most important temperature parameter indicators are: 1. Maximum temperature parameter; 2. Suitable temperature range. The maximum temperature parameter refers to the highest temperature that users can accept under different contact forms. The maximum temperature is an important parameter that needs to be referred to when designing mobile phone thermal experience test devices. The temperature of mobile phone thermal experience test devices cannot exceed the highest temperature that the human body can tolerate. The suitable temperature range is measured by evaluating the thermal sensation of the test subjects at ambient temperature. The selection of the suitable temperature range is directly related to whether the user can use the mobile phone comfortably.

[0005] In existing solutions, designers usually set the heat source layout of the mobile phone and the material of the parts in contact with the human body based on personal experience. However, the parameters set based on personal experience are highly subjective and are not suitable for the actual needs of most users. Summary of the invention

[0054] The present invention provides a mobile phone thermal experience testing device, in which the mobile phone thermal experience testing device includes a testing device body, the testing device body is a multi-layer structure, and its shape and size are close to those of a conventional mobile phone. In the prior art, a mobile phone will inevitably generate heat from its interior during use, and the heat generated inside the mobile phone generally has three diffusion directions: 1. Diffusion toward the screen; 2. Diffusion toward the back shell of the mobile phone; 3. Diffusion toward the side of the mobile phone. By setting the position of the heat source and designing the heat insulation and heat dissipation structure, the diffusion of heat in a certain direction can be increased or weakened, which will cause different thermal sensations in different areas of the mobile phone.

[0055] In order to improve the user experience of mobile phones, it is necessary to conduct a mobile phone thermal experience test, that is, to simulate the heat dissipation of various areas of the mobile phone under different usage methods through a test device, and then collect experience information, and continuously optimize the heat dissipation structure to obtain the best heat dissipation distribution method for a certain mobile phone.

[0056] The mobile phone thermal experience testing device provided by the present invention is used for thermal experience testing, which specifically includes:

[0057] 1. The front glass layer 1 used to simulate the mobile phone screen is selected according to the model of the screen of the simulated mobile phone. The glass material with the same or similar composition is selected as the manufacturing and processing material of the front glass layer 1, and then the selected glass is cut into the same shape as the simulated mobile phone screen (the length and width are the same, and the thickness can also be the same or slightly thicker). If the simulated mobile phone is a curved screen, the side of the front glass layer 1 can also be polished to form a curved structure. The front glass layer is inlaid with thermocouples as needed (a groove structure is set on the inner side of the front glass layer according to the layout position of the thermocouple, the shape of the thermocouple, the thermocouple routing and other factors, so as to fix the thermocouple on the front glass layer in an inlaid manner), and the thermocouple is used to monitor the temperature rise.

[0058] 2. A front pressure measuring layer 11 for measuring the degree of user's grip is set below the front glass layer and is cut and set according to the size of the front glass layer. If the simulated mobile phone has a curved screen, the shape changes with the front glass layer.

[0059] 3. A front heating layer used to simulate the internal heating of a mobile phone. The local temperature of the front heating layer is adjustable. The front heating layer is arranged on the rear side of the front glass layer 1 (if a front pressure measuring layer 11 is provided, the front heating layer is arranged below the front pressure measuring layer 11). The front heating layer is used to simulate the heat sensation formed by the internal heat of the mobile phone being transferred to the direction of the mobile phone screen. In the present invention, the setting area of ​​the front heating layer covers the entire front glass layer 1, and the local temperature of the front heating layer is adjustable. Specifically, the front heating layer includes a plurality of front heating layer units 6 whose heat generation can be independently controlled. The front heating layer unit 6 can be a small-sized square, rectangular or circular sheet heating body. The front heating layer unit 6 can convert electrical energy into thermal energy after being energized. Depending on the power supply, the heating amount and heating speed of the front heating layer unit 6 are different. The front heating layer unit 6 is preferably a square or rectangular structure, so that the size of the front heating layer unit 6 can be designed according to the design size of the front glass layer 1 (or the front heating layer). The design principle of the front heating layer unit 6 is: the number of units in the horizontal direction (the width direction of the test device body) is an integer, and the number of units in the vertical direction (the length direction of the test device body) is an integer. A small interval is maintained between adjacent front heating layer units 6, and the interval gap between adjacent front heating layer units 6 is kept consistent. The front glass layer 1 and the front heating layer are bonded with thermal conductive silicone to form a heat transfer connection structure to ensure heat transfer efficiency. If a front pressure measurement layer 11 is provided, the thermal conductive silicone wraps the front pressure measurement layer 11, so that the heat transfer efficiency can be ensured without affecting the pressure monitoring of the front pressure measurement layer 11.

[0060] 4. A rear heating layer for simulating the internal heating of a mobile phone, wherein the local temperature of the rear heating layer is adjustable, and the rear heating layer is arranged on the rear side of the front heating layer. In the present invention, the setting area of ​​the rear heating layer covers the entire back plate 2 (the area covered by the rear heating layer is the same as the area covered by the front heating layer), and the local temperature of the rear heating layer is adjustable. Specifically, the rear heating layer includes a plurality of rear heating layer units 7 that can independently control the amount of heat generated, and the rear heating layer unit 7 can be a small-sized square, rectangular or circular sheet heating body. After the rear heating layer unit 7 is powered on, the electrical energy can be converted into thermal energy. Depending on the power supply, the heating amount and the heating rate of the rear heating layer unit 7 are different. The rear heating layer unit 7 is preferably a square or rectangular structure. The design principle of the rear heating layer unit 7 is: the number of units is set to an integer in the horizontal direction (the width direction of the main body of the test device), and the number of units is set to an integer in the longitudinal direction (the length direction of the main body of the test device). A small interval is maintained between adjacent rear heating layer units 7, and the interval gap between adjacent rear heating layer units 7 is kept consistent.

[0061] 5. A rear pressure measuring layer 12 for measuring the degree of user's grip is set below the rear heating layer (or understood as the rear or back side). It is cut and set according to the size of the rear heating layer and the back plate. If the simulated mobile phone has a curved screen, the shape changes with the back plate.

[0062] 6. A side heating layer used to simulate the heating of the side of a mobile phone. The side heating layer is used to simulate the heat sensation formed by the heat inside the mobile phone being transferred to the side of the mobile phone. The side heating layer includes a plurality of side heating layer units 8 that can independently control the amount of heat generated. The side heating layer unit 8 is preferably a square or rectangular sheet heating body. The design principle of the side heating layer unit 8 is as follows: when it is arranged around the side of the main body of the test device, the number of settings on both the wide side and the long side is an integer. A small interval is maintained between adjacent side heating layer units 8, and the interval gap between adjacent side heating layer units 8 remains consistent.

[0064] 8. A back plate 2 for simulating the back of a mobile phone. The back plate 2 is arranged on the rear side of the rear pressure measuring layer 12. The back plate 2 forms a heat transfer connection structure with the rear heating layer through thermal conductive silicone, which is used to simulate the heat sensation formed by the internal heat of the mobile phone being transferred toward the back of the mobile phone. When the rear pressure measuring layer 12 is provided, the thermal conductive silicone wraps the rear pressure measuring layer 12, which can ensure the heat conduction efficiency without affecting the pressure monitoring of the rear pressure measuring layer 12. Furthermore, the back panel 2 is detachably connected to the rear heating layer. Specifically, the back panel 2 and the rear heating layer are connected by snap-fits. For example, a clamp is provided on the wide side of the back panel 2, and one or two clamps are provided on the long side of the back panel 2. A clamp slot is provided on the rear heating layer corresponding to each clamp. In this way, the back panel 2 can be detachably mounted on the rear heating layer through the cooperation of the clamp and the clamp slot. The back panel is embedded with thermocouples as needed (consistent with the method of setting thermocouples on the front glass layer, a groove structure is provided on the inner side surface of the back of the back panel according to the setting position of the thermocouple, the shape of the thermocouple and the wiring method, etc., for embedding and installing the thermocouple) to monitor the temperature rise.

[0065] 9. A side frame 3 is provided on the outer side of the side heating layer and around the side of the test device body.

Specifically, a side insulation layer 4 is provided between the side heating layer and the side of the test device body. Specifically, an interlayer insulation layer 5 is provided between the front heating layer and the rear heating layer. Specifically, a unit insulation layer 9 is provided between each heating layer unit. An interlayer insulation layer 5 is provided between the front heating layer and the rear heating layer, and the front heating layer and the rear heating layer are bonded to the shelf insulation layer 5 with ordinary glue. Specifically, in the present invention, the thermal insulation structure (including the side insulation layer 4, the interlayer insulation layer 5 and the unit insulation layer 9) is made of insulating asbestos board.

[0067] The front heating layer is similar to the rear heating layer in structure. The front heating layer is composed of a plurality of front heating layer units 6, the rear heating layer is composed of a plurality of rear heating layer units 7, and the side heating layer is composed of a plurality of side heating layer units 8.

For each heating unit, its heating power is feedback-controlled by the value of the temperature measuring point, and the heating amount is adjusted according to the temperature. For example, the present invention can be provided with three temperature controllers, which correspond to the front heating layer, the rear heating layer and the side heating layer, respectively.

[0068] In the present invention, the heat insulation structure is made of hard heat insulation material (insulating asbestos board), so that the front heating layer, the rear heating layer and the side heating layer can be stably installed under the premise of playing the role of heat insulation, and then the front glass layer, the back plate and the side frame can be fixedly installed. Of course, the front glass layer, the back plate and the side frame also have the function of reinforcing the entire test device.

[0069] As can be seen from the above, in the present invention, the back panel 2 is detachably connected to the rear heating layer; the side frame 3 is detachably connected to the side heating layer.

[0083] The side heating layer is composed of a number of small square blocks, that is, the side heating layer includes a plurality of side heating layer units 8, and the side heating layer units 8 can be square structures or rectangular structures. The side heating layer is located outside the side insulation layer, and each block can be individually temperature-controlled using an electric heating wire, and a separate insulation layer is provided in the middle of each block to prevent the temperature exchange between the side heating layer units 8 from affecting the test.

[0084] The side frame 3 of replaceable material is connected to the outer edge of the side heating layer through a snap-on structure. The material can be replaced according to needs, such as metal, glass, plastic, etc., and the shape can be replaced according to the front and rear screens, such as a right-angle side frame 3 and a curved side frame 3, etc.

[0085] In a specific embodiment of the present invention, the front heating layer is divided into 4*8 parts (four front heating layer units 6 are arranged horizontally, and eight rows of front heating layer units 6 are arranged vertically), the rear heating layer is divided into 4*8 parts (four rear heating layer units 7 are arranged horizontally, and eight rows of rear heating layer units 7 are arranged vertically), the left side heating layer is divided into 1*8 parts (eight side heating layer units 8 are arranged vertically), the right side heating layer is divided into 1*8 parts (eight side heating layer units 8 are arranged vertically), the top side heating layer is divided into 1*4 parts (four side heating layer units 8 are arranged horizontally on the top side), and the bottom side heating layer is divided into 1*4 parts (four side heating layer units 8 are arranged horizontally on the bottom side). Each of the above-mentioned heating units is connected to a corresponding electric heating wire for electrically heating each heating layer unit. Based on the above structure, each heating layer unit is adjusted to a specified temperature by an electric heating wire, and the temperature is monitored by thermocouples embedded in the front glass and the back plate. The temperature adjustment setting range is 0°C to 48°C, and the setting step of the temperature adjustment is 2°C (that is, for each adjustment action, the temperature increase or decrease of a heating layer unit is 2°C).

[0086] After the temperature distribution of the device is adjusted, a thermal experience experiment is conducted in the form of user experience, and the experience is given, that is, the subjective thermal sensation, comfort and satisfaction of the subjects at the contact positions of the front, two sides and back of the device (a total of four test surfaces) are measured at different temperatures and distributions, and the temperature threshold values ​​of the mobile phone are obtained when the back panel 2 and the sides are made of different materials, different heat source layouts, different shapes and sizes, and different contact forms (normal vertical holding of the hand, normal horizontal holding of the hand, ear-face contact when making a call, etc.), and the user's mobile phone thermal experience results in this scenario are obtained.

[0087] Regarding the use of user experience data, the present invention uses the following table for statistics: Table 1 below is a user experience data acquisition card in the present invention.

Back, that is, the position used to simulate the back of the mobile phone, which is the back panel 2 in the present invention. The three experience feelings include: 1. Thermal sensation; 2. Satisfaction; 3. Whether to continue using. In addition, there is also a cause analysis project for obtaining the reasons for the low experience, and the reasons include the hand holding tightness obtained by the pressure measurement layer. In the three experience feelings, thermal sensation and satisfaction correspond to the four experience aspects one by one. When collecting data, the experience personnel use a scoring system, for example, the full score is five points, five points is the most satisfactory, one point is the worst experience, and when the experience is ≤3 points, it is a poor experience, and the reasons for the poor experience need to be collected again. According to the experience information obtained by the above-mentioned user experience data collection card, the temperature and heat distribution are adjusted and optimized to obtain the best mobile phone thermal distribution data.

[0091] As can be seen from the above, the present invention provides a mobile phone thermal experience test device, which includes: a front glass layer 1 for simulating a mobile phone screen; a front pressure measurement layer 11 for determining the degree of user grip; a front heating layer for simulating the internal heating of the mobile phone, the local temperature of the front heating layer is adjustable, the front heating layer is arranged on the rear side of the front glass layer 1 and in contact with the front glass layer 1, and is used to simulate the heat sensation formed by the internal heat of the mobile phone being transferred to the direction of the mobile phone screen; a rear heating layer for simulating the internal heating of the mobile phone, the local temperature of the rear heating layer is adjustable, and the rear heating layer is arranged on the rear side of the front heating layer; a rear pressure measurement layer 12 for determining the degree of user grip; a back plate 2 for simulating the back of the mobile phone, the back plate 2 is arranged on the rear side of the rear heating layer and in contact with the rear heating layer, and is used to simulate the heat sensation formed by the internal heat of the mobile phone being transferred to the back of the mobile phone; and a test device body with a multi-layer structure formed by the front glass layer 1, the front heating layer, the rear heating layer and the back plate 2. At the same time, the present invention also provides a mobile phone thermal experience test method.
