When an electronic device falls during use, the shell of the electronic device is often subjected to external impact, and the shell is easily deformed and damaged under the action of external impact force, which reduces the reliability of the electronic device. Summary of the invention

[0003] The present application provides a shell and an electronic device. The shell has high strength. When the electronic device falls, the probability of the shell being deformed and damaged by an external impact force can be reduced, thereby improving the reliability of the electronic device.

[0004] In the first aspect, the present application provides a shell, including a frame and a support plate, the support plate is located on the inner side of the frame, the peripheral surface of the support plate is fixedly connected to the inner peripheral surface of the frame, the support plate is provided with a buffer groove, the buffer groove runs through the top surface of the support plate and the peripheral surface of the support plate, the groove side wall surface of the buffer groove is spaced and arranged opposite to the inner peripheral surface of the frame, and the support plate is provided with a plurality of reinforcing beams, the plurality of reinforcing beams are all arranged on the groove bottom wall surface of the buffer groove, and are spaced along the length direction of the buffer groove. Each reinforcing beam includes a first fixing portion, a second fixing portion and a connecting arm portion, the first fixing portion, the second fixing portion and the connecting arm portion are all arranged on the groove bottom wall surface of the buffer groove, the first fixing portion is fixedly connected to the inner peripheral surface of the frame, the second fixing portion is spaced from the first fixing portion and is fixedly connected to the groove side wall surface of the buffer groove, the connecting arm portion is fixedly connected between the first fixing portion and the second fixing portion, and along the length direction of the buffer groove, the width of the first fixing portion and the width of the second fixing portion are both greater than the width of the connecting arm portion.

[0005] In the shell shown in the present application, a buffer groove and a plurality of reinforcing beams are designed on the support plate, and the plurality of reinforcing beams are connected between the groove side wall surface of the buffer groove and the inner peripheral surface of the frame. The design of the buffer groove and the plurality of reinforcing beams can increase the overall strength of the shell. When the shell falls during use, not only the buffer groove can absorb the external impact force received by the shell, but the external impact force received by the shell can also be transmitted through the frame and dispersed to the plurality of reinforcing beams, so as to avoid deformation and damage of the shell, and reduce the probability of deformation and damage of the shell under the action of external impact force, which helps to improve the reliability of the use of electronic equipment.

[0006] In one embodiment, the buffer groove is in an elongated strip shape, and the length direction of the buffer groove is parallel to the circumference of the shell. Wherein, the circumference of the support plate and the circumference of the frame are both parallel to the circumference of the shell.

[0007] In one embodiment, multiple reinforcement beams are evenly spaced along the length direction of the buffer groove. When the shell falls during use, the external impact force received by the shell can be evenly transmitted and dispersed to the multiple reinforcement beams through the frame. The multiple reinforcement beams can relatively evenly share the external impact force, avoiding local deformation and damage of the shell under the action of the external impact force, and further improving the reliability of the electronic device.

[0008] In one embodiment, the frame includes a frame corner, the support plate includes a support corner, the support corner is fixedly connected to the inner side of the frame corner, and the buffer groove and the plurality of reinforcing beams are both provided at the support corner.

[0009] It is understandable that when the shell falls during use, the corners of the frame are easily deformed by external impacts. Designing buffer grooves and multiple reinforcing beams at the supporting corners of the support plate can prevent the corners of the frame from being deformed by external impacts, thereby ensuring the reliability of the shell.

[0010] In one embodiment, the frame includes multiple frame corners, the support plate includes multiple supporting corners, each supporting corner is fixedly connected to the inside of a frame corner, there are multiple buffer grooves, at least one buffer groove and multiple reinforcing beams are arranged on one supporting corner.

[0011] It is understandable that when the shell falls during use, the corners of the frame are easily deformed by external impacts. A buffer groove and multiple reinforcing beams are designed at each supporting corner of the support plate to prevent the multiple corners of the frame from being deformed by external impacts, thereby ensuring the reliability of the shell.

[0012] In one embodiment, the frame includes four frame corners, which are respectively a first frame corner, a second frame corner, a third frame corner and a fourth frame corner, and the first frame corner, the second frame corner, the third frame corner and the fourth frame corner are spaced apart from each other.

[0013] The support plate includes four support corners, which are respectively a first support corner, a second support corner, a third support corner and a fourth support corner. The first support corner is fixedly connected to the inner side of the first frame corner, the second support corner is fixedly connected to the inner side of the second frame corner, the third support corner is fixedly connected to the inner side of the third frame corner, and the fourth support corner is fixedly connected to the inner side of the fourth frame corner.

[0014] There are four buffer grooves, namely the first buffer groove, the second buffer groove, the third buffer groove and the fourth buffer groove. The first buffer groove is arranged at the first supporting corner, the second buffer groove is arranged at the second supporting corner, the third buffer groove is arranged at the third supporting corner, and the fourth buffer groove is arranged at the fourth supporting corner.

[0015] The multiple reinforcing beams include multiple first reinforcing beams, multiple second reinforcing beams, multiple third reinforcing beams and multiple fourth reinforcing beams. The multiple first reinforcing beams are all arranged on the bottom wall of the first buffer groove and are arranged at intervals along the length direction of the first buffer groove. The multiple second reinforcing beams are all arranged on the bottom wall of the second buffer groove and are arranged at intervals along the length direction of the second buffer groove. The multiple third reinforcing beams are all arranged on the bottom wall of the third buffer groove and are arranged at intervals along the length direction of the third buffer groove. The multiple fourth reinforcing beams are all arranged on the bottom wall of the fourth buffer groove and are arranged at intervals along the length direction of the fourth buffer groove.

[0016] Exemplarily, the frame is in the shape of a square frame, and the support plate is in the shape of a square plate.

[0017] It is understandable that when a shell (such as a square shell) falls during use, the four corners of the frame are easily deformed by external impacts. Buffer grooves and multiple reinforcing beams are designed at the four supporting corners of the support plate to prevent the four corners of the frame from being deformed by external impacts, thereby ensuring the reliability of the shell.

[0018] In one embodiment, along the length direction of the buffer groove, the width of each reinforcing beam is greater than or equal to 0.5 mm and less than or equal to 2 mm. Along the direction of the inner circumference of the groove side wall of the buffer groove facing the frame, the length of each reinforcing beam is greater than or equal to 1 mm and less than or equal to 5 mm. Along the thickness direction of the shell, the height of each reinforcing beam is greater than or equal to 0.5 mm and less than or equal to 2 mm. When the shell falls during use, the size design of the reinforcing beam can ensure that the reinforcing beam has sufficient strength to withstand the external impact force transmitted to the reinforcing beam by the frame, thereby ensuring the reliability of the shell.

[0019] In one embodiment, the frame is provided with a step groove, which passes through the top surface of the frame and the inner circumference of the frame and is arranged around the support plate. The step groove can be used to install the display screen of the electronic device, reduce the assembly space of the display screen on the housing, help reduce the volume of the housing, and help realize the miniaturization design of the electronic device.

[0020] In one embodiment, the distance between the side wall of the step groove and the outer surface of the frame is less than or equal to 0.8 mm, so as to realize a narrow frame design of the electronic device and ensure the exquisite appearance of the electronic device.

[0021] In one embodiment, the outer surface of the frame is parallel to the thickness direction of the housing to ensure the exquisite appearance of the electronic device.

[0022] In one embodiment, the housing further comprises a back cover, which is mounted on one side of the frame and spaced apart from the support plate. The back cover may be a battery cover of the electronic device.

[0023] In a second aspect, the present application provides an electronic device comprising a display screen and any one of the above-mentioned shells, the display screen comprising a protective cover plate and a display panel, the protective cover plate being installed on a frame, the display panel being installed between the protective cover plate and the support plate, and being spaced apart from the inner circumference of the frame.

[0024] In the electronic device shown in the present application, a buffer groove and a plurality of reinforcing beams are designed on the support plate, and the plurality of reinforcing beams are connected between the groove side wall surface of the buffer groove and the inner peripheral surface of the frame. The design of the buffer groove and the plurality of reinforcing beams can increase the overall strength of the shell. When the shell falls during use, not only can the buffer groove absorb the external impact force received by the shell, but the external impact force received by the shell can also be transmitted through the frame and dispersed to the plurality of reinforcing beams to avoid deformation and damage of the shell, which can reduce the probability of deformation and damage of the shell under the action of external impact force, and help to improve the reliability of the electronic device. Moreover, the design of the buffer groove and the reinforcing beam can also reduce the force transmitted by the shell to the display screen, and avoid damage and failure of the display screen.

[0025] In one embodiment, the electronic device further includes a first adhesive layer and a second adhesive layer, the first adhesive layer is bonded between the protective cover plate and the frame to achieve assembly between the protective cover plate and the frame, and the second adhesive layer is bonded between the display panel and the support plate to achieve assembly between the display panel and the support plate.

Wherein, cutting along II means cutting along the plane where II is located. Figure 2 The double-dotted line indicates Figure 2 Cut lines of the structure shown.

[0036] The electronic device 1000 may be an electronic product such as a mobile phone, a tablet computer, a laptop computer, a car computer, a smart watch, a smart bracelet, a POS machine (point of sales terminal), etc. Next, the embodiment of the present application is described by taking the electronic device 1000 as a mobile phone as an example. Among them, for the convenience of description, the width direction of the electronic device 1000 is defined as the X-axis direction, the length direction of the electronic device 1000 is defined as the Y-axis direction, and the thickness direction of the electronic device 1000 is defined as the Z-axis direction, and the X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other.

[0037] It should be noted that the qualifiers such as parallel and perpendicular mentioned in the embodiments of the present application regarding the relative position relationship are all for the current process level, rather than an absolute and strict definition in the mathematical sense. A small amount of deviation is allowed, and both approximately parallel and approximately perpendicular are acceptable. For example, A and B are parallel, which means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. For example, A and B are perpendicular, which means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0038] The electronic device 1000 includes a housing 100, a circuit board 200, a processor (not shown), a display screen 300, a first adhesive layer 400 and a second adhesive layer 500. The circuit board 200, the processor and the display screen 300 are all mounted on the housing 100. The first adhesive layer 400 and the second adhesive layer 500 are both located between the display screen 300 and the housing 100, and are bonded between the display screen 300 and the housing 100.

[0039] The housing 100 includes a frame 110 and a back cover 120, wherein the back cover 120 is mounted on one side of the frame 110. The frame 110 may be a middle frame of the electronic device 1000, and the back cover 120 may be a battery cover of the electronic device 1000. In some other embodiments, the frame 110 may also be other structural members in the electronic device 1000 for supporting.

[0040] Exemplarily, the electronic device 1000 further includes a third adhesive layer 600, which is located between the frame 110 and the back cover 120 and bonded between the frame 110 and the back cover 120 to achieve assembly between the frame 110 and the back cover 120. It is understandable that the back cover 120 can be detachably mounted on the frame 110 to facilitate maintenance and replacement of internal components or modules of the electronic device 1000.

[0041] The circuit board 200 and the processor are both installed on the inner side of the housing 100. The processor can be installed on the circuit board 200 and electrically connected to the circuit board 200. The circuit board 200 can be the mainboard of the electronic device 1000, and the processor can be the CPU (central processing unit) of the electronic device 1000. It should be noted that Figure 1 The dashed lines shown exemplarily show the position and shape of the circuit board 200, and do not indicate or imply that the circuit board 200 must have Figure 1 The specific positions and shapes shown are therefore not to be construed as limiting the present application.

[0042] The display screen 300 is mounted on the other side of the frame 110. Specifically, the display screen 300 is mounted on the side of the frame 110 away from the back cover 120. That is, the display screen 300 and the back cover 120 are respectively mounted on opposite sides of the frame 110. When the user uses the electronic device 1000, the display screen 300 is placed toward the user, and the back cover 120 is placed away from the user. Among them, the display screen 300 is electrically connected to the circuit board 200 to achieve electrical connection with the processor. The display screen 300 can receive the electrical signal sent by the processor through the circuit board 200, and display information such as images or text according to the electrical signal.

[0043] The display screen 300 includes a display panel 310, a protective cover plate 320, a transparent adhesive layer (not shown) and a connecting circuit board (not shown). The protective cover plate 320 is installed on the display side of the display panel 310 and covers the display surface of the display panel 310 to protect the display panel 310. Among them, the peripheral surface of the protective cover plate 320 protrudes relative to the peripheral surface of the display panel 310 to achieve comprehensive protection of the display panel 310. The transparent adhesive layer is located between the display panel 310 and the protective cover plate 320, and is bonded between the display panel 310 and the protective cover plate 320 to achieve assembly between the display panel 310 and the protective cover plate 320. One end of the connecting circuit board is electrically connected to the display panel 310, and the other end is electrically connected to the circuit board 200 to achieve electrical connection between the display screen 300 and the circuit board 200.

[0044] Exemplarily, the display panel 310 may be a display panel such as a liquid crystal display panel (LCD) or an organic light-emitting diode display panel (OLED), the protective cover plate 320 may be a glass cover plate (CG) made of glass, and the transparent adhesive layer may be made of an optically clear adhesive (OCA) or an optically clear resin (OCR).

[0045] Next, the structure of the display screen 300 is described by taking the display panel 310 as an organic light emitting diode display panel as an example.

[0046] Please also read Figure 3 , Figure 3 yes Figure 1 The cross-sectional structure diagram of the display screen 300 in the electronic device 1000 is shown.

[0047] The display panel 310 includes a base layer 311, a driving circuit layer 312, an organic light emitting layer 313 and an encapsulation layer 314, wherein the driving circuit layer 312, the organic light emitting layer 313 and the encapsulation layer 314 are sequentially stacked on one side of the base layer 311. The base layer 311 may be made of polyimide (PI), and the driving circuit layer 312 may include a plurality of thin film transistors (TFT).

[0048] In addition, the display screen 300 further includes a touch panel 340 and a polarizer (POL) 350, which are sequentially stacked on a side of the encapsulation layer 314 away from the organic light-emitting layer 313. The protective cover plate 320 is located on a side of the polarizer 350 away from the touch layer 340. The transparent adhesive layer 330 is located between the polarizer 350 and the protective cover plate 320, and is bonded between the polarizer 350 and the protective cover plate 320.

[0049] See also Figure 2 and Figure 4 , Figure 4 yes Figure 1 The schematic diagram of the structure of the frame 110 in the electronic device 1000 is shown. Figure 4 The double-dotted line indicates Figure 4 Cut lines of the structure shown.

[0050] The frame 110 includes a frame 111 and a support plate 112, and the support plate 112 is fixedly connected to the inner side of the frame 111. Specifically, the support plate 112 is located on the inner side of the frame 111, and the peripheral surface of the support plate is fixedly connected to the inner peripheral surface of the frame 111 (not shown). It should be understood that Figure 2 The dashed line shown exemplarily marks the boundary between the frame 111 and the support plate 112, and does not indicate or imply that the boundary between the frame 111 and the support plate 112 must be as shown. Figure 2 The positions and shapes indicated by the dotted lines are therefore not to be construed as limiting the present application.

[0051] Exemplarily, the frame 111 can be integrally formed with the support plate 112. The frame 111 can be made of plastic, and the support plate 112 can be made of a composite of plastic and metal, so as to reduce the cost of the frame 110 while ensuring the support strength of the support plate 112. It should be understood that the frame 111 and the support plate 112 can also be made of plastic, or the frame 111 and the support plate 112 can also be made of metal, and the present application does not specifically limit the materials of the frame 111 and the support plate 112.

[0052] In this embodiment, the outer peripheral surface of the frame 111 (not shown) is parallel to the thickness direction (Z-axis direction in the figure) of the housing 100. In other words, the outer peripheral surface of the frame 111 is designed in a right angle to ensure the exquisite appearance of the electronic device 1000. In some other embodiments, the outer peripheral surface of the frame 111 may not be parallel to the thickness direction of the housing 100, and this application does not make any specific restrictions on this.

[0053] The frame 111 is provided with a step groove 113, which passes through the top surface (not shown) and the inner circumference of the frame 111, and is arranged around the support plate 112. Specifically, the step groove 113 is recessed in the direction (negative direction of the Z axis shown in the figure) from the top surface to the bottom surface (not shown) of the frame 111. The bottom wall surface (not shown) of the step groove 113 is located on the top side of the top surface (not shown) of the support plate 112. Among them, the width W1 between the side wall surface (not shown) of the step groove 113 and the outer circumference of the frame 111 is less than or equal to 0.8 mm, so as to realize the narrow frame design of the electronic device 1000 and ensure the exquisite appearance of the electronic device 1000.

[0054] It should be noted that the terms "top", "bottom", "inside" and "outside" in this application are all referenced to the attached Figure 1 The description of the orientation shown, with the positive direction of the Z-axis as the "top", the negative direction of the Z-axis as the "bottom", the inside of the electronic device 1000 as the "inside", and the outside of the electronic device 1000 as the "outside", does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0055] See also Figure 2 , the display panel 310 and the protective cover plate 320 are both installed on the frame 110. Specifically, the display panel 310 is installed on the support plate 112. Among them, the display panel 310 and the connecting circuit board are both spaced apart from the inner circumference of the frame 111. The protective cover plate 320 is installed in the step groove 113 of the frame 111. Among them, the first adhesive layer 400 is located between the protective cover plate 320 and the bottom wall of the step groove 113, and is bonded between the protective cover plate 320 and the bottom wall of the step groove 113 to achieve the assembly between the protective cover plate 320 and the frame 110. The second adhesive layer 500 is located between the display panel 310 and the top surface of the support plate 112, and is bonded between the display panel 310 and the top surface of the support plate 112 to achieve the assembly between the display panel 310 and the frame 110. Among them, the first adhesive layer 400 and the second adhesive layer 500 can be made of adhesive adhesive such as foam adhesive.

[0056] In this embodiment, the protective cover 320 is installed on the step groove 113 of the frame 111 through the first glue layer 400. Compared with the method of installing it on the frame 111 by filling glue, the assembly space of the display screen 300 on the frame 110 can be reduced, which helps to reduce the volume of the frame 110 and realize the miniaturized design of the electronic device 1000.

[0057] It should be noted that when the electronic device 1000 falls during use, the frame 110 is often subjected to external impact, and the frame 110 is easily deformed under the action of the external impact force. In particular, when the frame 110 is made of plastic, the overall strength of the frame 110 is low, and the frame 110 may even be damaged under the action of the external impact force, which reduces the reliability of the electronic device 1000. Moreover, when the electronic device 1000 falls during use, relative movement occurs between the protective cover 320 and the frame 110. At this time, the frame 110 is not only subjected to the external impact force, but also to the shear force applied to the frame 110 by the protective cover 320. Under the dual action of the external impact force and the internal shear force, the frame 110 is more likely to collapse and be damaged.

[0058] In addition, when the electronic device 1000 falls during use, the external impact force borne by the frame 110 will also be transmitted to the display screen 300 through the first adhesive layer 400 and the second adhesive layer 500, causing the display screen 300 to be damaged and fail. It should be noted that when the electronic device 1000 falls during use, the broken position of the display screen 300 is often located at the encapsulation layer 314, and the water vapor and oxygen in the environment will enter the organic light-emitting layer 313 from the broken position of the encapsulation layer 314. Since the organic light-emitting layer 313 is extremely sensitive to water vapor and oxygen, the water vapor and oxygen will react with the organic matter in the organic light-emitting layer 313 to produce black spots and black spots, affecting the normal use of the display screen 300. Therefore, when the electronic device 1000 falls during use, the failure position of the display screen 300 generally appears at the edge of the display screen 300.

[0059] In the electronic device 1000 shown in this embodiment, the risk of plastic deformation of the frame 110 is reduced by improving the structure of the frame 110. When the electronic device 1000 falls, the impact and pulling of the housing 100 on the display screen 300 can be reduced, thereby preventing the display screen 300 from being damaged and failing, thereby ensuring the reliability of the electronic device 1000. Next, the frame 110 of the electronic device 1000 is described in detail.

[0060] See also Figure 5 , Figure 5 yes Figure 4 The partial structural diagram of the frame 110 is shown. Figure 5 The double-dotted line indicates Figure 5 Cut lines of the structure shown.

[0061] The support plate 112 is provided with a buffer groove 114, and the buffer groove 114 passes through the top surface of the support plate 112 and the circumference of the support plate 112 (not marked in the figure). Specifically, the buffer groove 114 is recessed in the direction (negative direction of the Z axis in the figure) from the top surface to the bottom surface (not marked in the figure) of the support plate 112. The buffer groove 114 includes a groove side wall surface 115, and the groove side wall surface 115 is spaced and arranged opposite to the inner circumference of the frame 111. Among them, the buffer groove 114 is a strip groove, and the length direction of the buffer groove 114 is parallel to the circumference of the support plate 112. It can be understood that the circumference of the support plate 112 is parallel to the circumference of the frame 111, the circumference of the frame 110 and the circumference of the shell 100.

[0062] Please also read Figure 6 , Figure 6 yes Figure 5 A schematic plan view of the structure of the reinforcing beam 116 in the frame 110 is shown.

[0063] The support plate 112 is further provided with a plurality of reinforcing beams 116, which are all provided on the bottom wall surface of the buffer groove 114 (not shown in the figure) and fixedly connected between the groove side wall surface 115 of the buffer groove 114 and the inner peripheral surface of the frame 111. The plurality of reinforcing beams 116 are sequentially arranged at intervals along the length direction of the buffer groove 114, and divide the buffer groove 114 into a plurality of sub-buffer grooves 117. The plurality of sub-buffer grooves 117 are sequentially arranged at intervals along the length direction of the buffer groove 114.

[0064] Among them, along the direction of the groove side wall surface 115 of the buffer groove 114 toward the inner circumference of the frame 111, the length L of each reinforcing beam 116 is greater than or equal to 1 mm and less than or equal to 5 mm. Along the length direction of the buffer groove 114, the width W2 of each reinforcing beam 116 is greater than or equal to 0.5 mm and less than or equal to 4 mm. Along the thickness direction of the shell 100 (Z-axis direction shown in the figure), the height H of each reinforcing beam 116 is greater than or equal to 0.5 mm and less than or equal to 2 mm. When the electronic device 1000 falls during use, the size design of the reinforcing beam 116 can ensure that the reinforcing beam 116 has sufficient strength to withstand the external impact force transmitted to the reinforcing beam 116 by the frame 111, thereby ensuring the reliability of the frame 110.

[0065] Each reinforcing beam 116 includes a first fixing portion 1161, a second fixing portion 1162 and a connecting arm portion 1163, and the first fixing portion 1161, the second fixing portion 1162 and the connecting arm portion 1163 are all arranged on the bottom wall surface of the buffer groove 114. The first fixing portion 1161 is fixedly connected to the groove side wall surface 115 of the buffer groove 114. Exemplarily, the top surface (not marked in the figure) of the first fixing portion 1161 is flush with the top surface of the support plate 112. The second fixing portion 1162 is spaced apart from the first fixing portion 1161 and arranged opposite to each other, and is fixedly connected to the inner peripheral surface of the frame 111. Exemplarily, the top surface (not marked in the figure) of the second fixing portion 1162 is located between the top surface of the support plate 112 and the bottom wall surface of the step groove 113. The connecting arm portion 1163 is located between the first fixing portion 1161 and the second fixing portion 1162, and is fixedly connected between the first fixing portion 1161 and the second fixing portion 1162. Exemplarily, the top surface of the connecting arm portion 1163 (not shown) is flush with the top surface of the first fixing portion 1161. In the length direction of the buffer groove 114, the width of the connecting arm portion 1163 is smaller than the width of the first fixing portion 1161 and the width of the second fixing portion 1162. In other words, the reinforcing beam 116 is in an "I" shape.

[0066] It should be understood that Figure 6 The dashed line shown exemplarily identifies the boundary between the first fixing portion 1161, the second fixing portion 1162 and the connecting arm portion 1163, and does not indicate or imply that the boundary between the first fixing portion 1161, the second fixing portion 1162 and the connecting arm portion 1163 must be as shown in FIG. Figure 6 The positions and shapes indicated by the dotted lines are therefore not to be construed as limiting the present application.

[0067] In the electronic device 1000 shown in this embodiment, a buffer groove 114 and a plurality of reinforcing beams 116 are designed on the frame 110. When the electronic device 1000 falls, not only can the external impact force received by the frame 110 be transmitted through the frame 111 and dispersed to the plurality of reinforcing beams 116, but also the sub-buffer grooves 117 between adjacent reinforcing beams 116 can absorb the external impact force received by the frame 110, thereby preventing the frame 110 from being deformed and damaged, and reducing the probability of deformation and damage of the housing 100 under the action of the external impact force, which helps to improve the reliability of the electronic device 1000. Moreover, the design of the buffer groove 114 and the plurality of reinforcing beams 116 can also reduce the force transmitted from the housing 100 to the display screen 300, thereby preventing the display screen 300 from being damaged and failing, thereby improving the anti-fall performance of the electronic device 1000 and ensuring the reliability of the electronic device 1000.

[0068] Exemplarily, along the length direction of the buffer groove 114, a plurality of reinforcing beams 116 are evenly spaced and distributed, and a plurality of sub-buffer grooves 117 are evenly spaced and distributed. When the housing 100 falls during use, the external impact force received by the housing 100 can be evenly transmitted and dispersed to the plurality of reinforcing beams 116 through the frame 111. The plurality of reinforcing beams 116 can relatively evenly share the external impact force transmitted by the frame 111, thereby preventing the housing 100 from being locally deformed and damaged under the action of the external impact force, and further improving the reliability of the electronic device 1000.

[0069] Please also read Figure 1 and Figure 4 In this embodiment, the frame 110 is in the shape of a rectangular parallelepiped. In some other embodiments, the frame 110 may also be cylindrical or other special shapes, and the present application does not specifically limit the shape of the frame 110. The frame 111 is in the shape of a square frame. The frame 111 includes four frame corners 119, which are respectively located at the four corners of the support plate 112 and are spaced apart from each other. The four frame corners 119 are respectively a first frame corner 119a, a second frame corner 119b, a third frame corner (not shown) and a fourth frame corner (not shown). The first frame corner 119a is located at the upper left corner of the support plate 112, the second frame corner 119b is located at the lower left corner of the support plate 112, the third frame corner is located at the upper right corner of the support plate 112, and the fourth frame corner is located at the lower right corner of the support plate 112. In some other embodiments, the frame 111 may not be in the shape of a square plate, and the frame 111 may include less than three or more than five frame corners 119 , and the present application does not impose any specific limitation on this.

[0070] It should be noted that the directional terms such as "upper", "lower", "left" and "right" involved in this application are all referenced to the attached Figure 4 The description of the orientation shown, with the positive direction of the Y-axis as "up", the negative direction of the Y-axis as "down", the positive direction of the X-axis as "right", and the negative direction of the X-axis as "left", does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0071] The support plate 112 is in the shape of a square plate. The support plate 112 includes four support corners 118, and the four support corners 118 are respectively located at the four corners of the support plate 112. The four support corners 118 are respectively a first support corner 118a, a second support corner 118b, a third support corner (not shown) and a fourth support corner (not shown). The first support corner 118a is located at the upper left corner of the support plate 112 and is fixedly connected to the inner side of the first frame corner 119a. The second support corner 118b is located at the lower left corner of the support plate 112 and is fixedly connected to the inner side of the second frame corner 119b. The third support corner is located at the upper right corner of the support plate 112 and is fixedly connected to the inner side of the third frame corner. The fourth support corner is located at the lower right corner of the support plate 112 and is fixedly connected to the inner side of the fourth frame corner. In some other embodiments, the support plate 112 may not be in the shape of a square plate, and the support plate 112 may include less than three or more than five support corner portions 118, and the present application does not impose any specific limitation on this.

[0072] There are four buffer grooves 114, which are respectively arranged at the four supporting corners 118 of the supporting plate 112. The four buffer grooves 114 are respectively a first buffer groove 114a, a second buffer groove (not shown), a third buffer groove (not shown) and a fourth buffer groove (not shown). The first buffer groove 114a is arranged at the first supporting corner 118a, the second buffer groove is arranged at the second supporting corner 118b, the third buffer groove is arranged at the third supporting corner, and the fourth buffer groove is arranged at the fourth supporting corner.

[0073] The plurality of reinforcing beams 116 include a plurality of first reinforcing beams 116a, a plurality of second reinforcing beams (not shown), a plurality of third reinforcing beams (not shown) and a plurality of fourth reinforcing beams (not shown). The plurality of first reinforcing beams 116a are all arranged on the bottom wall of the first buffer groove 114a, the plurality of second reinforcing beams are all arranged on the bottom wall of the second buffer groove, the plurality of third reinforcing beams are all arranged on the bottom wall of the third buffer groove, and the plurality of fourth reinforcing beams are all arranged on the bottom wall of the fourth buffer groove.

[0074] It is understandable that when the electronic device 1000 falls during use, the four corners 119 of the frame 111 are easily deformed by external impacts. Buffer grooves 114 and multiple reinforcing beams 116 are designed at the four supporting corners 118 of the support plate 112 to prevent the four corners 119 of the frame 111 from being deformed by external impacts, thereby ensuring the reliability of the electronic device 1000.

[0075] It should be noted that, in some other embodiments, the supporting corners 118 of the supporting plate 112 may also be provided with more than two buffer grooves 114, and / or, only one, two or three of the four supporting corners 118 of the supporting plate 112 may be designed with buffer grooves 114 and reinforcing beams 116, and / or, other parts of the supporting plate 112 except the four supporting corners 118 may also be designed with buffer grooves 114 and reinforcing beams 116. The present application does not impose any specific restrictions on the number and positions of the buffer grooves 114 and reinforcing beams 116.

[0076] It should be understood that the "and / or" mentioned in the embodiments of the present application refers to both "and" and "or". For example, "and / or" includes three situations: only existence, only existence, and and existence at the same time. The following description of "and / or" can be understood in the same way.

[0077] See also Figure 7 , Figure 7 yes Figure 4 The simulation diagram shows the plastic strain occurring when the upper left corner of the frame 110 falls at 45 degrees.

[0078] in, Figure 7 In the simulation diagram of plastic strain shown, the dark black part indicates the existence of yield stress, and the grayish white part indicates the risk of fracture. Figure 7 It can be seen that when the frame 110 shown in this embodiment falls at 45 degrees, only yield stress exists on the frame 111 without the risk of fracture, and stress is concentrated only at the reinforcing beam 116 of the support plate 112 and there is a risk of fracture. In other words, in the frame 110 shown in this embodiment, the "I"-shaped reinforcing beam 116 is designed on the support plate 112 to increase the overall strength of the frame 110. When the frame 110 falls, most of the stress borne by the frame 111 can be transferred to the reinforcing beam 116 of the support plate 112, thereby preventing the frame 110 from being deformed and damaged.

[0079] In the electronic device 1000 shown in this embodiment, a buffer groove 114 and a reinforcing beam 116 are designed on the frame 110. When the electronic device 1000 falls, not only can the external impact force received by the frame 110 be transmitted through the frame 111 and dispersed to the multiple reinforcing beams 116, but the sub-buffer grooves 117 between adjacent reinforcing beams 116 can absorb the external impact force received by the frame 110, thereby preventing the frame 110 from being deformed and damaged, and reducing the probability of the housing 100 being deformed and damaged under the action of the external impact force, which helps to improve the reliability of the electronic device 1000. Moreover, the design of the buffer groove 114 and the multiple reinforcing beams 116 can also reduce the force transmitted from the housing 100 to the display screen 300, thereby preventing the display screen 300 from being damaged and failing, thereby improving the anti-fall performance of the electronic device 1000 and ensuring the reliability of the electronic device 1000.
