A top view of a drop-resistant housing provided by a preferred embodiment of the present utility model for an ultra-thin construction electronic device is shown in fig. 2.
The anti-falling casing 100 for an electronic device with an ultrathin structure in this embodiment includes a bottom 1, and a screen support platform 2 extending from the periphery of the bottom 1, where the screen support platform 2 includes a pair of long-side support platforms 21 and 23 and a pair of short-side support platforms 22 and 24, and the bottom 1 and the screen support platform 2 form a cavity 3 for accommodating main functional components such as a display screen, a battery, and a circuit board;
as shown in fig. 2, 4 groups of buffer structures 81, 82, 83, 84 are arranged at 4 angular positions of the screen bearing platform 2, and the buffer structures are composed of honeycomb holes and fillers;

fig. 3 is an enlarged partial schematic view of the honeycomb structure of fig. 2.
Besides the angle position, other areas of the screen bearing platform 2 are not necessary to be provided with holes, and the contact surface is large and the pressure intensity is small when falling, so that the screen bearing platform is not easy to deform; in addition, since the screen table 2 is used for bonding the screen glass, if the holes are too many, the bonding area is reduced, and the bonding effect of the screen glass is affected.
The filler is silica gel or foam, the hardness range is 40% -60%, the filler is used for filling the honeycomb holes, the size of the filler is consistent with that of the corresponding holes, and the filler of each hole is a whole.
When the electronic equipment is produced and assembled, the holes are filled manually by operators, and in order to achieve a better buffering effect, the filler is a one-step formed integral body and cannot use scraps.
All holes 801, 802 and 803 on the corner are right cylinders, the heights of the holes are the same as those of the screen bearing platform 2, and the upper surfaces of the holes are flush with the upper surface of the screen bearing platform 2; the diameters of the upper surfaces of the short-side holes 801 and the long-side holes 803 are consistent, and are 56% -84% of the width of the screen bearing platform 2, and the diameter of the upper surface of the angular hole 802 is 100% -120% of the diameter of the upper surface of the short-side hole 801.
The center of the upper surface of the angular hole 802 is positioned on the connecting line of the corresponding angle and the opposite angle of the upper surface of the screen bearing platform 2; the distance between the axes of the short side holes 801 and the angular holes 802 is 80% -120% of the sum of the diameter of the upper surface of the angular holes 802 and the radius of the upper surface of the short side holes 801, the distance between the axes of the long side holes 803 and the angular holes 802 is 80% -120% of the sum of the diameter of the upper surface of the angular holes 802 and the radius of the upper surface of the short side holes 801, the distance between the axes of two adjacent holes on the long side is 80% -120% of the radius of the upper surface of the long side holes 803, and the distance between the axes of the adjacent holes on the short side is 80% -120% of the radius of the upper surface of the short side holes (801).
The lower surfaces of the holes in the 4 corners of the screen bearing platform 2 are positioned at the inner side of the bottom of the shell, the holes do not penetrate through the bottom, so that the holes can not be seen from the back of the electronic equipment, after the glass cover plate is installed on the screen bearing platform 2, the glass cover plate is completely attached to the screen bearing platform 2, and the holes can not be seen from the front of the electronic equipment, so that the buffer structure in the 4 corners does not influence the appearance of the electronic equipment.
The anti-drop housing 100 is made of metal, ensures strength, and is convenient for forming, for example, aluminum or aluminum alloy.
The screen bearing platform 2 is used for being attached to a glass cover plate, and the height and the width of the bearing platform are matched to accommodate main functional components such as a display screen, a battery and a circuit board. The width of the bearing platform changes along with the size of the electronic product, the larger the size of the electronic product is, the larger the size of the required glass cover plate is, and the larger the width of the bearing platform is required for ensuring the attaching effect.
The screen bearing platform 2 is provided with a switch key hole 4, an earphone hole 5, a sound cavity hole 6 and a USB hole 7, and other external interfaces such as a volume key can be also arranged.
The switch key hole 4, the earphone hole 5, the sound cavity hole 6 and the USB hole 7 respectively correspond to the shapes and the sizes of a switch key, an earphone interface, a loudspeaker sound cavity and a USB interface of the electronic equipment. These openings are typically designed in the side of the electronic device near the corners to facilitate handling, and require an open window in the metal housing or metal frame, which can have some loss of strength.
Taking a USB hole as an example, through mechanical drop simulation test, it is found that under the multiple factors of thin metal shell, too narrow frame and the like, when a product suffers drop impact, the deformation of the long side of the USB hole reaches 55%, the deformation of the short side of the USB hole reaches 53%, the drop simulation test effect is as shown in fig. 4-5, and the deformation of the level can hurt internal functional components.
The parameters for the simulation test are as follows:
product size: 245.66 x 187.33 x 4, units mm;
drop scene: standard test;
sample state: starting up;
falling materials: 3cm high density wood board;
drop height: 80cm;
drop direction: 6 face 4 angle;
drop sequence: bottom surface → right side surface → top surface → left side surface → rear surface → front surface → upper left corner → lower right corner → upper right corner → lower left corner.
On the premise of not changing the appearance, the utility model can effectively reduce the deformation of the shell caused by drop test by adding the buffer structure at the corners.
The simulation result of the embodiment of the utility model shows that after the buffer structure is added at the corners, the mechanical drop simulation test is carried out again, the deformation of the long side of the USB hole is less than 20%, the deformation of the short side is less than 10%, and the drop resistance effect is obvious.
Through the physical test of the embodiment of the utility model, the product using the buffer structure shell can pass the drop test smoothly.
The parameters of the product during the physical test are as follows:
product size: 245.66 x 187.33 x 4, units mm;
bearing platform width: 3mm;

number of corner holes: 1, a step of;
number of holes on long side: 2;
diameter of upper surface of side hole: 2.1mm;
diameter of upper surface of corner hole: 2.5mm.
The working principle of the embodiment is as follows: in the falling process, the electronic equipment collides with the ground, the metal on the outer side of the honeycomb structure deforms to form first buffering, the filling soft cushion in the honeycomb forms second buffering on the impact force, and after twice buffering, the solid deformation of the inner side of the honeycomb is obviously smaller than that of the outer side, so that a good anti-falling effect is achieved.
The anti-falling shell of the embodiment is provided with a group of buffer structures comprising honeycomb holes and elastic fillers at the 4 corners of the screen bearing platform under the condition that the appearance of the electronic equipment is not affected, and the deformation degree of the shell is effectively reduced through buffering in the falling process, so that the internal functional components are better protected.
The embodiments of the present utility model have been described above with reference to the accompanying drawings, but the present utility model is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and many modifications may be made thereto by those of ordinary skill in the art without departing from the spirit of the present utility model and the scope of the appended claims, which fall within the protection of the present utility model.
