Description

Technical Field

[0001] The present invention relates to the technical field of electronic products, and particularly to a device with high drop strength. Background Art

[0002] With the development of science and technology, intelligent handheld electronic devices such as mobile phones and tablet computers are everywhere in life. Most of these devices use touch screens for collection and recognition for interaction. However, during use, different from fixed devices, handheld electronic devices have the risk of accidental drops. The drop heights vary, the surfaces on which they drop also differ, and drops can cause irreversible damage such as casing deformation and screen breakage;

[0003] Therefore, improving the overall drop strength of the device can not only improve the overall service life of the device to a certain extent, but also enhance the user experience, greatly reducing the probability of screen breakage due to drops. Summary of the Invention

[0004] To solve the technical problems raised in the background art, the present invention provides a device with high drop strength.

[0005] The present invention is implemented by the following technical solutions: A device with high drop strength includes a casing and a cover plate. One side of the casing is open for installing the cover plate.

[0006] A first buffer cavity and a second buffer cavity are provided inside the casing. Both the first buffer cavity and the second buffer cavity open on the side where the cover plate is provided, and sealing plates are detachably installed at the openings.

[0007] A buffer layer is provided between the cover plate and the inner wall of the casing.

[0008] As a further improvement of the above solution, the casing on both sides of the first buffer cavity is respectively an inner casing and an outer casing, and the second buffer cavity is opened in the inner casing.

[0009] Through the above structural design, the device can have better anti-drop strength.

[0010] As a further improvement of the above solution, a number of first communication holes are opened in the casing between the first buffer cavity and the second buffer cavity. A buffer air cushion is provided in the first buffer cavity, and a pressure cavity is formed between the buffer air cushion and the inner wall of the first buffer cavity. One side port of the first communication hole communicates with the pressure cavity.

[0011] Through the above structure, when the casing is subjected to collision and extrusion, the buffer air cushion deforms, causing the gas therein to enter the second buffer cavity through the first communication hole, increasing the air pressure therein, and further preventing the deformation of the two side casings, achieving a good buffering effect.

[0012] As a further improvement of the above solution, a number of second communication holes are provided in the housing on the side of the second buffer chamber away from the first buffer chamber. The buffer layer is hollow inside, and a notch is provided on the side of the buffer layer that fits against the inner wall of the housing. The notch is internally connected to each of the second communication holes and is also connected to the hollow interior.

[0013] When the housing is deformed due to a collision, causing a change in the air pressure inside the second buffer chamber, the gas inside it enters the notch through the second communication holes. Through the notch, it can enter the interior of the buffer layer, thereby causing a change in the air pressure inside the buffer layer, being able to resist deformation, and effectively protecting the cover plate.

[0014] As a further improvement of the above solution, a number of contact heads are provided on the inner side of the sealing plate located inside the first buffer chamber, which can contact the outer side of the buffer air cushion.

[0015] The contact heads provided can effectively squeeze the air cushion, making the effect of absorbing kinetic energy better.

[0016] As a further improvement of the above solution, the openings of the first buffer chamber and the second buffer chamber are integrally annular, and the cross-section of the opening has a rectangular section and a circular section. A number of sockets are provided at the rectangular section, and a buffer member is installed in each circular section.

[0017] Through the above design, the first buffer chamber and the second buffer chamber can be sealed to prevent dust from entering the interior, and the structural stability can be further enhanced. A circular elastic sealing ring can be installed on the outer ring of the sealing plate, which can buffer collisions and enhance the sealing effect.

[0018] As a further improvement of the above solution, the buffer member includes a buffer sleeve inserted into the circular section and a central cylinder installed in the buffer sleeve. Among them, the buffer sleeve is made of a soft material, the central cylinder is made of a hard material, and a support unit is installed on the central cylinder to support the inner side wall of the buffer sleeve.

[0019] As a further improvement of the above solution, the support unit includes a top rod passing through the central cylinder, a piston column located inside the central cylinder and fixed to the top rod, and a piston cylinder movably sleeved outside the piston column. A through hole for the piston cylinder to pass through is provided on the housing of the central cylinder, and the outer end of the piston cylinder is connected to a telescopic airbag. A variable-volume pressurizing chamber is formed between the piston cylinder and the piston column, and the pressurizing chamber is gas-connected to the telescopic airbag.

[0020] When the buffer proposed by the above solution is in use and during installation, the outer wall of the buffer sleeve fits against the inner wall of the buffer cavity. When the shells on both sides of the buffer cavity are deformed and squeeze the buffer sleeve, the ejector rod is driven to move, causing the piston rod to slide within the piston cylinder, squeezing the telescopic airbag, increasing the volume of the telescopic airbag, and thus increasing the air pressure within the buffer cavity. This can resist the tendency of the internal space of the buffer cavity to become smaller due to deformation on both sides, playing a good buffering role and effectively protecting the cover plate.

[0021] As a further improvement of the above solution, several clamping plates are provided on the inner surface of the sealing plate. The clamping plates are used to be inserted into the rectangular section, and side plates are provided on both opposite sides of the clamping plates. The side plates are used to dock with the jacks.

[0022] With the above structure, it is more convenient to install the sealing plate.

[0023] As a further improvement of the above solution, the clamping plate is a rigid plate, and the side plate is made of a soft material and has scalability. With the above design, it can take into account the strength while also having a certain buffering effect.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] An equipment with high drop strength proposed by the present invention includes a casing and a cover plate. One side of the casing is open for installing the cover plate. A buffer cavity one and a buffer cavity two are provided inside the casing. Both the buffer cavity one and the buffer cavity two are open on the side where the cover plate is provided, and a sealing plate is detachably installed at the opening. A buffer layer is provided between the cover plate and the inner wall of the casing. The casings on both sides of the buffer cavity one are respectively an inner casing and an outer casing, and the buffer cavity two is provided in the inner casing. Through the above structural design of the present invention, the equipment can have better anti-drop strength.

[0026] The openings of the buffer cavity one and the buffer cavity two proposed by the present invention are integrally annular, and the cross-section of the opening has a rectangular section and a circular section. Several sockets are provided at the rectangular section, and a buffer member is installed in each circular section; the buffer member includes a buffer sleeve inserted into the circular section and a central cylinder installed in the buffer sleeve. Among them, the buffer sleeve is made of a soft material, the central cylinder is made of a rigid material, and a support unit is installed on the central cylinder to support the inner side wall of the buffer sleeve. The support unit includes an ejector rod passing through the central cylinder, a piston rod fixed to the ejector rod within the central cylinder, and a piston cylinder movably sleeved outside the piston rod. A through hole for the piston cylinder to pass through is provided on the shell of the central cylinder, and the outer end of the piston cylinder is connected to a telescopic airbag. A variable-volume pressurizing cavity is formed between the piston cylinder and the piston rod, and the pressurizing cavity is in gas communication with the telescopic airbag.

[0027] Through the above structural design of the present invention, it can have a better buffering effect, making the overall equipment have good drop strength. Brief Description of the Drawings

Detailed Embodiment

[0036] Next, in combination with the drawings and specific embodiments, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination of the following described embodiments or technical features can form a new embodiment.

[0037] Embodiment 1:

[0038] Specifically referring to Figures 1-6 , a device with high drop strength includes a casing 1 and a cover plate 3. One side of the casing 1 is open for installing the cover plate 3.

[0039] A first buffer cavity 2 and a second buffer cavity 8 are provided inside the casing 1. Both the first buffer cavity 2 and the second buffer cavity 8 are open on the side where the cover plate 3 is provided, and a sealing plate 4 is detachably installed at the opening.

[0040] A buffer layer 10 is provided between the cover plate 3 and the inner wall of the casing 1.

[0041] As a further improvement of the above solution, the casings 1 on both sides of the first buffer cavity 2 are respectively an inner casing 101 and an outer casing 102, and the second buffer cavity 8 is opened in the inner casing 101.

[0042] Through the above structural design, the device can have better anti-drop strength.

[0043] As an optional implementation manner of the present invention, a plurality of first communication holes 7 are opened in the casing 1 between the first buffer cavity 2 and the second buffer cavity 8, and a buffer air cushion 6 is arranged in the first buffer cavity 2. A pressure cavity is formed between the buffer air cushion 6 and the inner wall of the first buffer cavity 2, and one side port of the first communication hole 7 is communicated with the pressure cavity.

[0044] Through the above structure, when the casing is subjected to collision and extrusion, the buffer air cushion 6 compresses, so that the gas therein enters the second buffer cavity 8 through the first communication hole 7, increasing the air pressure therein, which can further prevent the deformation of the two side casings and play a good buffering effect.

[0045] As an optional implementation manner of the present invention, a plurality of second communication holes 9 are opened in the casing 1 on the side of the second buffer cavity 8 away from the first buffer cavity 2. The buffer layer is hollow inside, and a notch is provided on the side of the buffer layer 10 that fits the inner wall of the casing 1. The notch is internally communicated with each of the second communication holes 9 and is also communicated with the hollow part.

[0046] When the casing is collided and deformed, causing a change in the air pressure in the second buffer cavity 8, the gas therein enters the notch through the second communication holes 9. Through the notch, it can enter the inside of the buffer layer, thereby changing the air pressure inside the buffer layer, which can resist deformation and effectively protect the cover plate 3.

[0047] As an optional implementation manner of the present invention, a plurality of contact heads 401 that can contact the outer side of the buffer air cushion 6 are arranged on the inner side of the sealing plate 4 located in the first buffer cavity 2.

[0048] Through the arranged contact heads 401, the air cushion 6 can be effectively squeezed, making the effect of absorbing kinetic energy better.

[0049] As an optional implementation manner of the present invention, the openings of the first buffer cavity 2 and the second buffer cavity 8 are integrally annular, and the cross-section of the opening has a rectangular section and a circular section. A plurality of sockets 404 are opened at the rectangular section 402, and a buffer member is installed in each circular section.

[0050] Through the above design, the first buffer cavity 2 and the second buffer cavity 8 can be sealed to prevent dust from entering the inside, and the structural stability can be further enhanced. A circle of elastic sealing rings can be installed on the outer ring of the sealing plate 4, which can buffer collisions and enhance the sealing effect.

[0051] Embodiment 2:

[0052] For details, reference may be made to Figures 4-6 As an optional embodiment of the present invention, the buffer member includes a buffer sleeve 13 inserted into the circular section and a central cylinder 14 installed in the buffer sleeve 13. Among them, the buffer sleeve 13 is made of a soft material, the central cylinder 14 is made of a hard material, and a support unit supported on the inner side wall of the buffer sleeve 13 is installed on the central cylinder 14.

[0053] As an optional embodiment of the present invention, the support unit includes a push rod 12 passing through the central cylinder 14, a piston column 15 located in the central cylinder 13 and fixed to the push rod 12, and a piston cylinder 16 movably sleeved outside the piston column 15. A through hole for the piston cylinder 16 to pass through is formed on the housing of the central cylinder 13, and a telescopic airbag 17 is connected to the outer end of the piston cylinder 16. A variable-volume pressurized chamber is formed between the piston cylinder 16 and the piston column 15, and the pressurized chamber is connected to the telescopic airbag 17 through air.

[0054] When the buffer member proposed in the above solution is in use, during installation, the outer wall of the buffer sleeve 13 fits against the inner wall of the buffer cavity. When the housings on both sides of the buffer cavity are deformed and squeeze the buffer sleeve 13, the push rod 12 is driven to move, causing the piston column 15 to slide in the piston cylinder 16 and squeeze the telescopic airbag 17, so that the volume of the telescopic airbag 17 increases, thereby increasing the air pressure in the buffer cavity, being able to resist the tendency of the internal space of the buffer cavity to become smaller due to the deformation on both sides, playing a good buffering role and effectively protecting the cover plate.

[0055] As an optional embodiment of the present invention, a plurality of clamping plates 19 are provided on the inner surface of the sealing plate 4. The clamping plates 19 are used for plugging into the rectangular section 402, and side plates 20 are provided on both opposite sides of the clamping plates 19. The side plates 20 are used for docking with the jacks 404.

[0056] With the above structure, it is more convenient to install the sealing plate 4.

[0057] As an optional embodiment of the present invention, the clamping plates 19 are hard plates, and the side plates 20 are made of a soft material and have scalability. With the above design, it can take into account the strength while also having a certain buffering effect.

[0058] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantive changes and substitutions made by those skilled in the art based on the present invention fall within the scope of protection required by the present invention.
