Technical Field
[0001] The utility model relates to the technical field of electronic equipment, in particular to an ultra-thin tablet computer. Background Art
[0002] In the past, most tablet computers were designed with rubber feet, primarily to prevent them from sliding off smooth work surfaces or other sloped surfaces, thereby preventing damage. However, with technological advancements and rising consumer tastes, demands for tablet computers have expanded beyond functionality to include a more refined aesthetic. Consequently, product designers are constantly striving to make their products lighter and thinner.
[0003] However, the thinner the product design, the more susceptible its frame is to deformation, making controlling this deformation a critical challenge for designers. Existing similar products typically use small, solid rubber feet. While rubber feet offer a certain degree of elasticity, their limited thickness limits their compression. In ultra-thin tablets, this design can leave some feet suspended in the air, compromising product stability, weakening their anti-slip properties, and failing to compensate for the flatness variations caused by micro-deformation in the ultra-thin tablet frame.
[0004] Therefore, a new foot pad design is needed that can not only meet the requirements of product lightness and thinness, but also effectively prevent the product from slipping, while ensuring the stability of the foot pad under various usage conditions and compensating for the flatness differences of ultra-thin tablet computers.

[0008] The bottom shell is provided with a foot pad positioning hole; the foot pad positioning hole is a cylindrical structure, the depth of the foot pad positioning hole is less than the natural height of the foot pad; the diameter of the foot pad positioning hole is equal to the outer diameter of the connecting portion; the connecting portion is connected to the bottom surface of the foot pad positioning hole;
[0009] A foot pad protection dam is provided on the bottom shell along the edge of the foot pad positioning hole, wherein the foot pad protection dam has a maximum height at the edge of the foot pad positioning hole and the height of the foot pad protection dam gradually decreases in a direction away from the foot pad positioning hole;
[0010] The sum of the height of the foot pad positioning hole and the maximum height of the foot pad protection embankment is less than the natural height of the foot pad and greater than the minimum height of the foot pad when deformed;

[0029] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described in detail with reference to the accompanying drawings.
[0030] The technical solution of the utility model is applicable to ultra-thin handheld tablet computer products of 10 inches and above.
[0031] like Figure 1-9 As shown, an embodiment of the present invention provides an ultra-thin tablet computer, comprising a bottom shell 1 and a foot pad 2 assembled on the bottom shell 1. The bottom shell 1 refers to the side of the outer shell opposite the tablet computer display screen. The bottom shell 1 of the tablet computer is usually placed on a supporting surface, and the foot pad 2 provides an anti-slip function.
[0032] The foot pad 2 includes a connecting portion 21 and a supporting portion 22; the connecting portion 21 is connected to the bottom shell 1, and the supporting portion 22 is in contact with the supporting surface of the ultra-thin tablet computer; the connecting portion 21 is an annular cylindrical structure, and the supporting portion 22 is an arc surface structure protruding outward along one end of the connecting portion 21; the foot pad 2 is made of a flexible material as a whole and deforms under the action of gravity of the ultra-thin tablet computer; the natural height of the foot pad 2 is the sum of the height of the connecting portion 21 and the height of the supporting portion 22 when it is not deformed.
[0033] Unlike the prior art, which employs small, solid foot pads on ultra-thin tablet computers, in the embodiment of the present invention, the connecting portion 21 is an annular cylindrical structure. After the foot pad 2 is assembled to the tablet computer bottom shell 1 via the connecting portion 21, the bottom shell 1, the connecting portion 21, and the supporting portion 22 enclose a closed chamber. Therefore, the foot pad 2 in the embodiment of the present invention has a hollowed-out structure. Furthermore, because the foot pad 2 is entirely made of a flexible material, the structure reduces the retraction force of a single foot pad 2, facilitating rapid retraction when the central area of the foot pad 2 is stressed, thereby reducing the overall height of each foot pad 2. The outer surface of the supporting portion 22 is a rounded top, ensuring that the center of the foot pad 2 lands first. When the foot pad 2 is subjected to less stress or is in a natural state, the rounded top of the supporting portion 22 arches outward to its highest position. When the foot pad 2 is subjected to stress, the center of the foot pad 2 partially retracts, increasing the contact area while reducing the height of the foot pad 2. In summary, the design of the present invention makes the elastic range of the foot pad 2 along the height direction larger. When subjected to force compression, the height change range of the foot pad 2 is larger, which can improve the stability of the product, prevent the foot pad from hanging in the air, and effectively compensate for the flatness deviation problem caused by deformation of the ultra-thin tablet computer.
[0034] In some embodiments of the present invention, the foot pad 2 is made of soft silicone rubber. In addition to silicone rubber, other flexible materials can also be used. In actual application, the flexible material is tested according to its softness and wear resistance to select the appropriate material.
[0035] The bottom shell 1 is provided with a foot pad positioning hole 11 ; the foot pad positioning hole 11 is a cylindrical structure, and the depth of the foot pad positioning hole 11 is smaller than the natural height of the foot pad 2 ; the connecting portion 21 is connected to the bottom surface of the foot pad positioning hole 11 .
[0036] In the embodiment of the present invention, the foot pad positioning hole 11 is fixed to the connecting portion 21 by bonding. In some embodiments of the present invention, the foot pad 2 is made of silicone rubber and is bonded to the bottom surface of the foot pad positioning hole 11 using a dedicated silicone adhesive.
[0037] In this embodiment of the present invention, the diameter of the foot pad positioning hole 11 is equal to the outer diameter of the connecting portion 21. The foot pad positioning hole 11 is formed inwardly within the bottom shell 1, and the diameter of the foot pad positioning hole 11 is equal to the outer diameter of the connecting portion 21, so that the periphery of the foot pad 2 is tightly wrapped by the foot pad positioning hole 11, effectively preventing the foot pad 2 from falling off.
[0038] In this embodiment of the present invention, the outer diameter of the connecting portion 21 is greater than 5% of the width of the ultra-thin tablet computer. Unlike the prior art practice of installing small-sized foot pads on ultra-thin tablet computers, the outer diameter of the connecting portion of the foot pad 2 in this embodiment is greater than 5% of the tablet computer's width, representing a large-sized foot pad. This large-sized foot pad increases the contact area between the foot pad 2 and the load-bearing surface, thereby increasing the friction between the foot pad 2 and the load-bearing surface and effectively improving the anti-slip effect.
[0039] In an embodiment of the present utility model, a foot pad protection dam 12 is provided on the bottom shell 1 along the edge of the foot pad positioning hole 11. The foot pad protection dam 12 has a maximum height at the edge of the foot pad positioning hole 11, and the height of the foot pad protection dam 12 gradually decreases in the direction away from the foot pad positioning hole 11. The sum of the height of the foot pad positioning hole 11 and the maximum height of the foot pad protection dam 12 is less than the natural height of the foot pad 2, and greater than the minimum height of the foot pad 2 when deformed. The height of the foot pad positioning hole 11 and the foot pad protection dam 12 is set according to the overall height of the foot pad 2 and the actual situation of the ultra-thin tablet computer product. Generally, the height of the foot pad protection dam 12 is less than the height of the foot pad positioning hole 11.
[0040] like Figure 4-Figure 5 As shown, the foot pad protection ridge 12 is a raised structure formed on the flat bottom case 1. The foot pad positioning hole 11 is surrounded by the foot pad protection ridge 12, and the foot pad protection ridge 12 transitions from the edge of the foot pad positioning hole 11 to the surface of the bottom case 1 in an arc shape. When the ultra-thin tablet is pushed horizontally on the support surface and the foot pad 2 encounters an obstacle and is damaged by lateral shear force, the foot pad protection ridge 12 acts as a guide, redirecting the shear force from the obstacle and preventing it from directly shearing the foot pad 2, thus providing protection for the foot pad 2.
[0041] In an embodiment of the present invention, the ultra-thin tablet computer includes four foot pad positioning holes 11, which are symmetrically arranged on the bottom shell 1 of the ultra-thin tablet computer. In actual use, the foot pad positioning holes 11 are located near the four corners of the bottom shell 1. The position of the foot pad positioning holes 11 from the edges of the tablet computer is determined by aesthetic considerations. The closer the foot pad positioning holes 11 are to the edges of the tablet computer, the better the force and flatness compensation effects. In one embodiment of the present invention, the length, width, and height of the ultra-thin tablet computer are 210mm, 154mm, and 5.8mm, respectively. The diameter of the foot pad positioning holes is 10mm, which is 6.5% of the width of the ultra-thin tablet computer. The center of the foot pad positioning holes is 15mm away from each edge of the ultra-thin tablet computer.
[0042] In some embodiments of the present invention, a vent hole 13 is provided at the center of the bottom surface of the foot pad positioning hole 11, extending through the bottom shell 1. This vent hole 13 is used to vent air from the hollowed-out area when the foot pad 2 is deformed under stress, reducing the rebound force of the foot pad 2 and meeting the product's customized requirements for the height of the foot pad 2. In some embodiments of the present invention, this vent hole 13 is a circular hole with a diameter of 2 mm.
[0043] In this embodiment of the present invention, the difference between the outer and inner diameters of the connecting portion 21 is determined based on the weight of the ultra-thin tablet computer. The annular area at the bottom of the connecting portion 21 serves as the effective bonding area with the foot pad positioning hole 11. A smaller area results in a weak bond, while a larger area results in a smaller hollow portion, affecting the height range of the foot pad 2. In practical applications, the outer diameter of the connecting portion 21 is determined based on the tablet computer's width, and the difference between the outer and inner diameters is determined based on the tablet computer's weight.
[0044] In some embodiments of the present invention, the thickness of the support portion 22 is determined based on the weight of the ultra-thin tablet computer. In practical applications, the thickness of the support portion 22 is determined through mechanical simulation. In addition to the weight of the tablet computer, the dimensions and materials of the various components of the foot pad 2 also influence the design thickness of the support portion 22. The greater the thickness of the support portion 22, the greater the initial deformation force of the inner central hollow area of each foot pad 2. In some embodiments of the present invention, the thickness of the support portion 22 is determined through testing so that the initial deformation force of the inner central hollow area of each foot pad 2 is one-fifth of the total mass of the product. This ensures that under normal conditions, when all four foot pads 2 are evenly stressed, each foot pad 2 slightly retracts and deforms, providing sufficient grip. If the ultra-thin tablet computer experiences slight deformation, causing individual foot pads 2 to lose strength, the adjacent foot pads 2 will be affected by the tablet computer's own weight, causing them to retract more and lower their height. The foot pads 2 experiencing less stress will retract little or not at all, thus meeting the basic requirement of an ultra-thin tablet computer product for all four foot pads 2 to maintain grip, preventing end users from noticing any slight deformation. The current industry consensus is to control the flatness of ultra-thin tablet computers to within 0.5mm. In one embodiment of the present invention, the natural height of the foot pad 2 is 1.3mm. When the foot pad 2 is at its natural height, the vertical distance between the top of the support portion 22 and the bottom case 1 is 0.85mm, and the compression limit height is 0.65mm. Therefore, the maximum height difference between the four foot pads 2 can reach 0.65mm, which can effectively compensate for the flatness differences within the acceptable range.
[0045] In some embodiments of the present invention, the foot pads 2 are bonded to the foot pad positioning holes 11 using a dedicated silicone adhesive. During assembly, glue is applied to the connection portion 21 of the foot pad 2 and the flat bonding surface of the foot pad positioning hole 11 using a dedicated adhesive applicator. After the adhesive is allowed to dry for 5 minutes and becomes non-sticky, both are heated at 60 degrees Celsius for 30 seconds. After removal, the foot pads 2 are attached to the foot pad positioning holes 11. The housing 1, with the four foot pads installed, is then placed with the foot pads 2 facing downward into a dedicated pressure-maintaining fixture for bonding the foot pads for 30 seconds. Finally, the housing with the foot pads is assembled into the ultra-thin tablet computer product.
[0046] In addition to tablet computers, the foot pad provided by the present invention can also be applied to other electronic products, such as speakers, weight scales, etc. Referring to the tablet computer in the embodiment of the present invention, foot pad positioning holes and protective embankments corresponding to the foot pads can be set on these electronic products.
[0047] The present invention has the following beneficial effects: This solution provides an ultra-thin tablet computer, comprising a bottom shell and a foot pad assembled on the bottom shell, the foot pad comprising a connecting portion and a supporting portion; the connecting portion is an annular cylindrical structure, the supporting portion is an arc-shaped structure protruding outward along one end of the connecting portion, and the supporting portion contacts the load-bearing surface of the ultra-thin tablet computer; the foot pad is entirely made of a flexible material and deforms under the action of gravity of the ultra-thin tablet computer; the outer diameter of the connecting portion is greater than 5% of the width of the ultra-thin tablet computer; a foot pad positioning hole for connecting the foot pad is provided on the bottom shell; the diameter of the foot pad positioning hole is equal to the outer diameter of the connecting portion; and a foot pad protection embankment is provided on the bottom shell along the edge of the foot pad positioning hole. The foot pad of the present invention is a large-sized flexible structure with a hollowed-out middle portion, which increases the contact area between the foot pad and the load-bearing surface and improves the anti-slip performance. The foot pad has a large elastic range along the height direction, which can ensure the stability of the foot pad under various usage conditions and effectively compensate for the flatness differences of the ultra-thin tablet computer.
[0048] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms of deformation without departing from the scope of protection of the purpose of the present invention and the claims, which are all within the protection of the present invention.
