[0039] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.
[0040] On the one hand, combined with Figures 1 to 4 As shown, this embodiment provides a mobile terminal, which includes: a middle frame module 100 and a screen module 200 .
[0041] The screen module 200 is connected to the middle frame module 100; a buffer structure 1 is provided between the screen module 200 and the middle frame module 100, and the buffer structure 1 includes at least two buffer layers arranged in a stacked manner, wherein the modulus of at least one buffer layer is different from the modulus of the remaining buffer layers.
[0042] In the mobile terminal of this embodiment, a buffer structure 1 is provided between the middle frame module 100 and the screen module 200. The buffer structure 1 is formed by stacking at least two buffer layers, wherein the modulus of one buffer layer is different from the modulus of the remaining buffer layers. The high-modulus buffer layer is used to make the buffer structure 1 have higher strength and can resist the impact of the middle frame module 100 on the screen module 200. The low-modulus buffer layer can absorb the impact energy between the middle frame module 100 and the screen module 200. The use of multiple buffer layers with different moduli can effectively avoid the stress concentration impact of the middle frame module 100 on the screen module 200, thereby preventing the screen module 200 from having a broken bright spot problem.
[0043] Among them, modulus refers to the ratio of stress to strain of a material under stress, which describes the relative size of the deformation of a material when it is subjected to a force and the corresponding stress. The unit of modulus is usually Pa (Pascal) or MPa (MegaPascal). By way of example, in this embodiment, the modulus is used to measure the deformation capacity of the buffer layer within the elastic range, that is, the ability of the buffer layer to resist elastic deformation. A larger modulus means that the buffer layer can withstand a larger stress without significant plastic deformation, thereby preventing the middle frame module 100 from directly impacting the screen module 200 after the buffer structure 1 is over-compressed; a smaller modulus means that the buffer layer can undergo significant plastic deformation after being subjected to stress, thereby gradually consuming and absorbing the impact energy.
[0044] In some possible implementations, the screen module 200 includes any one of a plasma display panel (PDP), a vacuum fluorescent display (VFD), a field emission display (FED), an electroluminescent display (LED), an organic light-emitting diode display (OLED), a liquid crystal display (LCD), a micro-electro-mechanical system display (DMD), and an electronic ink (EL) display.
[0045] Exemplarily, the screen module 200 is Figure 1 2D screen (or flat screen) as shown, or Figure 2 The 2.5D screen (or curved screen) shown.
[0046] In some possible implementations, the screen module 200 includes a display panel (Panel), and the structure of the display panel has various forms.
[0047] Exemplarily, the display panel includes a substrate, an organic light-emitting diode (OLED) layer, and a thin film encapsulation (TFE) layer which are stacked in sequence.
[0048] In another exemplary embodiment, the display panel includes a substrate, a thin film transistor (TFT) layer, an organic light-emitting diode (OLED) layer, a thin film encapsulation (TFE) layer, a touch layer and a polarizer which are stacked in sequence.
[0049] It should be noted that the layer structure of the display panel is not limited to the two structural forms listed above. Under the condition of meeting the requirements of folding display, the display panel can also adopt other layer structure forms.
[0050] Combination Figure 4 As shown, in some embodiments, the buffer structure 1 includes a first buffer layer 11 and a second buffer layer 12, the first buffer layer 11 and the second buffer layer 12 are stacked, and the first buffer layer 11 is located on the side of the second buffer layer 12 facing the middle frame module 100, and the second buffer layer 12 is located on the side of the first buffer layer 11 facing the screen module 200; the modulus of the first buffer layer 11 is greater than the modulus of the second buffer layer 12.
[0051] Through the above arrangement, the first buffer layer 11 near the middle frame module 100 in the buffer structure 1 has a larger modulus and can withstand greater stress without significant plastic deformation, thereby preventing the middle frame module 100 from directly impacting the screen module 200 after the buffer structure 1 is over-compressed. The second buffer layer 12 near the screen module 200 has a smaller modulus and can undergo significant plastic deformation after being impacted by stress, thereby gradually consuming and absorbing impact energy. Compared with the buffer structure 1 with a single modulus, the buffer structure 1 with the first buffer layer 11 and the second buffer layer 12 has a composite effect and can provide a better buffer protection effect.
[0052] In some embodiments, the elastic modulus of the first buffer layer 11 is greater than the elastic modulus of the second buffer layer 12. The elastic modulus can be regarded as an indicator of the ease with which the buffer layer can be elastically deformed. The larger the value, the greater the stress that causes the buffer layer to undergo a certain elastic deformation, that is, the greater the stiffness of the buffer layer, that is, the smaller the elastic deformation under a certain stress.
[0053] In some possible implementations, the first buffer layer 11 is an EPP layer. EPP is the abbreviation of expanded polypropylene, which is the abbreviation of a new type of foam plastic. EPP material has higher mechanical strength, and has the advantages of light weight, good elasticity, shock and compression resistance, high deformation recovery rate, and good absorption performance. The second buffer layer 12 is an EPE (Expanded Polyethylene, polyethylene foam) layer, or pearl cotton layer. It is composed of countless independent bubbles produced by physical foaming of low-density polyethylene grease, and has many advantages such as waterproof and moisture-proof, shockproof, soundproof, heat-insulating, good plasticity, strong toughness, recycling, environmental protection, and strong impact resistance.
[0054] Combination Figure 4 As shown, in some embodiments, the buffer structure 1 is connected to the surface of the screen module 200 facing the middle frame module 100. Through the above arrangement, the buffer structure 1 is connected to the screen module 200, so that it can be pre-assembled with the screen module 200 first, and then assembled to the middle frame module 100 together with the screen module 200, which can reduce the difficulty of assembling the buffer structure 1.
[0055] Combination Figure 4 As shown, in some embodiments, the screen module 200 includes a screen protection layer 3, and the buffer structure 1 is connected to the surface of the screen protection layer 3 facing the middle frame module 100. Exemplarily, the screen protection layer 3 includes a metal layer, or at least one screen buffer layer.
[0056] The metal layer is located on the bottom surface of the screen module 200 facing the middle frame module 100. For example, the metal layer is copper foil, steel sheet, etc. The metal layer is arranged on the bottom surface of the screen module 200, which can protect the screen module 200 on the one hand, and prevent electromagnetic interference between the screen module 200 and the electronic components in the middle frame module 100 on the other hand.
[0057] In this embodiment, the buffer structure 1 is connected to the metal layer, and the metal layer can be used to further improve the protection performance of the screen module 200.
[0058] The at least one screen buffer layer is located inside the metal layer, and together with the buffer structure 1 and the metal layer, can protect the bottom of the screen module 200. Exemplarily, the screen buffer layer includes but is not limited to a foam layer, a foam layer, and the like.
[0059] Combination Figure 3 As shown, in some embodiments, the screen module 200 includes at least one corner area 2001 , and the buffer structure 1 is located between the at least one corner area 2001 and the middle frame module 100 .
[0060] Considering that the corner areas 2001 of the screen module 200 are far apart from each other and are located at a high incidence of collision and impact, arranging the buffer structure 1 in the corner area 2001 of the screen module 200 can reduce the risk of damage to the screen module 200.
[0061] Combination Figure 3 As shown, in some embodiments, the screen module 200 includes four corner areas 2001, and a buffer structure 1 is provided between at least one of the four corner areas 2001 and the middle frame module 100. The buffer structure 1 can be arranged on one of the four corner areas 2001, or on multiple of the four corner areas 2001.
[0062] Combination Figure 3 As shown, in some embodiments, the middle frame module 100 includes at least one mass concentration area 1001 , and the buffer structure 1 is located between the at least one mass concentration area 1001 and the screen module 200 .
[0063] Considering that after the mobile terminal falls, the mass concentration area 1001 is subjected to greater inertia, and the mass concentration area 1001 has a greater stress impact on the screen module 200, which is a stress concentration area. Arranging the buffer structure 1 in the mass concentration area 1001 of the middle frame structure can reduce the risk of damage to the screen module 200.
[0064] Combination Figure 3 , 4 As shown, in some embodiments, a motor assembly 2 is provided in at least one mass concentration area 1001, and a buffer structure 1 is located between the motor assembly 2 and the screen module 200. The motor assembly 2 is used to provide mechanical vibration for the mobile terminal, which is suitable for message reminders, incoming call reminders and other vibration feedback scenarios.
[0065] The motor assembly 2 has a large mass, and the motor assembly 2 is in an assembled relationship with the middle frame module 100. After the middle frame module 100 contacts the ground, the motor assembly 2 will generate a large stress impact under the action of inertia. The buffer structure 1 is arranged between the motor assembly 2 and the screen module 200 to reduce the risk of the screen module 200 being damaged by the impact of the motor assembly 2.
[0066] In some embodiments, the middle frame module 100 includes at least one shape undulating region (not shown in the figure), and the buffer structure 1 is located between the at least one shape undulating region and the screen module 200. The shape undulating region in the middle frame module 100 may form structures such as local sharp corners, and the buffer structure 1 can be used to provide targeted protection for the screen module 200 corresponding to the shape undulating region.
[0067] In some other possible implementations, the middle frame module 100 also includes at least one low rigidity area (not shown in the figure). Since other electronic components need to be stacked or avoided in this area, the structural height of the middle frame module 100 is relatively low, and it is easy to undergo flexible deformation when it falls and impacts. A buffer structure 1 is arranged in this area to provide targeted protection for the screen module 200.
