[0031] The present invention is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted under different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.
[0032] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.
[0033] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).
[0034] Adsorption devices typically generate suction force through the vacuum environment created within the adsorbent, so the tightness of the adhesion between the adsorbent and the wall surface is crucial. In some use cases, the wall surface to be adsorbed may be curved or have some bumps or pits. Although the adsorbent is generally made of flexible materials, due to its limited degree of deformation, it cannot completely conform to the wall surface.
[0035] In view of the above situation, a corrugated edge portion 22 can be provided at the edge of the adsorbent 2. On the one hand, as a part of the adsorbent 2, the edge portion 22 itself is made of a relatively soft material and can produce a certain degree of deformation to adapt to the surface shape of the wall. On the other hand, the corrugated structure of the edge portion 22 enables it to deform axially to further conform to the wall surface, which is suitable for walls with large curvatures and high unevenness.
[0036] It should be noted that the placement of the suction device shown in the following figures is intended only to illustrate its structure and should not be construed as limiting its intended use. For example, the suction device can be used to secure a mobile phone in a vehicle: the suction member 2 at one end of the base 1 faces downward and adheres to the vehicle, while the bracket 4 at the other end of the base 1 faces upward and is used to hold the phone. In other application scenarios, the suction device can also be arranged with the suction member 2 facing upward and the bracket 4 facing downward.
[0037] Please refer to Figures 1-6 In one embodiment, an adsorption device is provided, including: a seat body 1, an adsorption component 2 and an air extraction device 3.
[0038] The adsorbent 2 includes a main body 21 and an edge 22. The main body 21 is connected to the base 1, and the edge 22 is connected to the outer periphery of the main body 21. The edge 22 is used to adhere to the wall surface to be adsorbed to form a closed space inside the adsorbent 2. The main body 21 can be circular, square, etc., and the edge 22 is arranged around the outer periphery of the main body 21. The adsorbent 2 can be made of a flexible material such as rubber, silicone, soft PVC (Polyvinyl Chloride), etc. The material of the main body 21 can be the same as or different from the material of the edge 22. For example, the material of the edge 22 is more flexible than that of the main body 21 and has better adhesion to the wall surface.
[0039] The main body 21 and the base 1 can be connected by injection molding. Specifically, the main body 21 can be provided with a snap structure, and the base 1 can be fixed to the snap of the main body 21 by injection molding. After the edge 22 of the adsorbent 2 is in contact with the wall surface, the gas in the adsorbent 2 can be extracted by the exhaust device 3, or the gas in the adsorbent 2 can be expelled by squeezing, so that the adsorbent 2 is fixed to the wall surface under the action of the internal and external pressure difference.
[0040] The edge portion 22 extends in a corrugated shape along the axial direction of the adsorbent 2, and the edge portion 22 can be deformed along the axial direction of the adsorbent 2 to fit the wall surface. An air hole 211 is provided on the main body 21, and the air extraction device 3 is provided in the seat body 1 and connected to the air hole 211. The air extraction device 3 is used to extract the gas in the adsorbent 2 through the air hole 211. Specifically, the extension trajectory of the edge portion 22 can be a smooth curve or a broken line. The ability of the edge portion 22 to deform along the axial direction of the adsorbent 2 should be understood as follows: on the one hand, the edge portion 22 can be extended or shortened along the axial direction as a whole; on the other hand, part of the edge portion 22 can be convex or concave, for example, part of the edge portion 22 is convex to fit the pit on the wall surface, and part of the edge portion 22 is concave to fit the protrusion on the wall surface. For example, see Figure 8 For a wall surface 6 having a curved shape, the edge portion 22 can be partially convex or concave to adapt to the shape of the wall surface 6 .
[0041] In the above embodiment, when the wall surface to be adsorbed is curved or uneven, the various parts of the edge portion 22 can be deformed along the axial direction to adapt to the shape of the wall surface, and then fully fit with the wall surface; after the edge portion 22 is fully fitted with the wall surface, the airtightness between the adsorption part 2 and the wall surface is better, and air leakage is not easy to occur, and the adsorption device adsorbs the wall surface more firmly.
[0042] In some embodiments, please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6The edge portion 22 has an adsorption surface 221 away from the main body portion 21, and an annular ridge 222 is provided on the adsorption surface 221. The annular ridge 222 is arranged around the circumference of the edge portion 22, and the annular ridge 222 is used to seal and fit with the wall surface.
[0043] The surface of the edge portion 22 away from the main body portion 21 is the adsorption surface 221, and the adsorption surface 221 is used to directly fit with the wall surface. The adsorption surface 221 can be an annular surface, and the annular ridge 222 is located on the annular surface. The annular ridge 222 can be closed as a whole, or it can include multiple sections of discontinuous ridges. The annular ridge 222 and the edge portion 22 can be an integrated structure, or the annular ridge 222 is fixed to the edge portion 22 by bonding or clamping. The material of the annular ridge 222 is a flexible material. The provision of the annular ridge 222 can improve the degree of fit between the edge portion 22 and the wall surface, thereby improving the airtightness between the adsorption component 2 and the wall surface. In other embodiments, an annular groove can also be provided on the adsorption surface 221.
[0044] In some embodiments, please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 At least two annular ridges 222 are provided, and the two annular ridges 222 are spaced apart in the radial direction of the adsorption member 2. In this embodiment, there are three annular ridges 222, which are concentrically spaced apart, with one annular ridge 222 located at the edge of the edge portion 22. In other embodiments, the number of annular ridges 222 can also be two, four, five, etc.
[0045] In some embodiments, please refer to Figure 5 The cross-sectional area of the annular ridge 222 gradually decreases in the direction away from the adsorption surface 221. In this embodiment, the cross-sectional shape of the annular ridge 222 is triangular. In other embodiments, the shape of the annular ridge 222 can also be trapezoidal, semicircular, semi-elliptical, etc. In this arrangement, the annular ridge 222 is more likely to deform when in contact with the wall, thereby fully conforming to the wall.
[0046] In some embodiments, the edge portion 22 includes a trough section 223 that protrudes toward the center of the main portion 21, and / or the edge portion 22 includes a peak section that protrudes away from the center of the main portion 21. In this embodiment, the edge portion 22 only includes the trough section 223 that protrudes toward the center of the main portion 21. The edge portion 22 can be stretched or contracted in its entirety or in part along the axial direction of the adsorbent 2 to adapt to curved or uneven wall surfaces, thereby allowing the edge portion 22 to more fully adhere to the wall surface.
[0047] In other embodiments, the edge portion 22 may also include only one peak section, or the edge portion 22 may include several connected peak sections and trough sections 223 .
[0048] In some embodiments, please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 , the cross-sectional shape of the edge portion 22 along the axial direction is V-shaped. The edge portion 22 can be folded along the axial direction, and of the two surfaces that fit together after folding, one surface is provided with a groove 224, and the other surface is provided with a protrusion 225 that fits the groove 224. The cross-sectional shape refers to the shape of the cross section of the edge portion 22 cut out along the axial direction of the adsorbent 2, and since the edge portion 22 is connected to the main body 21, the cross-sectional shape of the adsorbent 2 as a whole is S-shaped. In the above arrangement, the adsorbent 2 can be deformed along the axial direction to adapt to the shape of the wall, thereby improving the fit. After the edge portion 22 is folded along the axial direction, the two surfaces on the outside of the edge portion 22 fit together, and the protrusion 225 fits in the groove 224. The provision of the groove 224 and the protrusion 225 can position the two parts folded together on the edge portion 22, and the edge portion 22 is not prone to torsional deformation and air leakage.
[0049] In some embodiments, please refer to Figure 6 , the axial projection of the edge portion 22 is located inside the main body 21. For the disc-shaped adsorbent 2, the axial projection of the edge portion 22 is located inside the main body 21, which can be understood as the outer diameter of the edge portion 22 is not greater than the inner diameter of the main body 21. In the above arrangement, when the adsorbent 2 is evacuated by the vacuum device 3, the main body 21 gradually moves toward the edge portion 22. Since the outer diameter of the edge portion 22 is smaller than that of the main body 21, the main body 21 can cover and press the edge portion 22. The edge portion 22 is not prone to warping or displacement, and the adsorption of the adsorbent 2 to the wall is more secure.
[0050] In some embodiments, please refer to Figure 9 ( Figure 9 Only the main body 21 of the adsorption member 2 is shown, and the edge portion 22 is not shown. The structure of the edge portion 22 can be the same as that of the adsorption member 2. Figure 1 The structure of the middle edge portion 22 is the same as that of the main body portion 21. A first flow channel 212 is provided on the inner wall of the main body portion 21. The first flow channel 212 extends radially of the main body portion 21. A plurality of protrusions 213 are provided on the inner wall of the main body portion 21. The protrusions 213 extend radially of the main body portion 21, and a first flow channel 212 is formed between two adjacent protrusions 213.
[0051] Specifically, the shape of the protrusion 213 can be fan-shaped. During the process of evacuating the interior of the adsorbent 2, the protrusion 213 will gradually fit against the wall surface, and the groove between the two adjacent protrusions 213 forms a first flow channel 212. The gas can converge to the pore 211 along the first flow channel 212, avoiding the situation where the part of the main body 21 close to the pore 211 fits against the wall surface, resulting in the gas in the rest of the part being unable to be extracted. By providing the first flow channel 212, the internal gas of the adsorbent 2 can be extracted more fully, the internal and external pressure difference of the adsorbent 2 is greater, and the adsorption force of the adsorbent 2 is stronger. In other embodiments, the shape of the protrusion 213 can also be triangular, trapezoidal, etc.
[0052] In some embodiments, see Figure 1 、 Figure 2 and Figure 6 A second flow channel 214 is provided on the inner wall of the main body 21. The second flow channel 214 extends circumferentially around the main body 21 and communicates with the first flow channel 212. The main body 21 is provided with multiple groups of protrusions 213. Each group of protrusions 213 is arranged in an annular array on the main body 21. Adjacent groups of protrusions 213 are spaced apart in the radial direction of the main body 21. The second flow channel 214 is formed between the two adjacent groups of protrusions 213. Within each group of protrusions 213, the first flow channel 212 is formed between two adjacent protrusions 213.
[0053] The second flow channel 214 is connected to the first flow channel 212 and arranged crosswise, which can fully connect the internal space of the adsorbent 2. During the process of exhausting the adsorbent 2 through the exhaust device 3, the gas can flow along the first flow channel 212 and the second flow channel 214. Even if the part of the main body 21 close to the air hole 211 is in contact with the wall, it cannot hinder the gas flow. The exhaust process is smoother, the gas in the adsorbent 2 can be extracted to the maximum extent, the pressure difference between the inside and outside of the adsorbent 2 is greater, and the adsorbent 2 has a greater adsorption force.
[0054] In some embodiments, please refer to Figure 5 and Figure 7 The adsorption device includes a bracket 4 for securing an object. The bracket 4 is rotatably connected to the base 1 to adjust the placement angle of the object. Specifically, the bracket 4 may be an annular bracket 4. The base 1 may be provided with a rotating shaft 42, on which the bracket 4 is rotatably mounted. The bracket 4 can be used to hold a mobile phone, and the placement angle of the mobile phone can be adjusted by rotating it.
[0055] In some embodiments, please refer to Figure 5 and Figure 7, the annular bracket 4 may also be embedded with a magnetic part, which can be used to adsorb electronic devices, such as mobile phones. Alternatively, the magnetic part is used to adsorb metal walls, and the adsorption part 2 is used to adsorb electronic devices and other items. The annular bracket 4 may also be provided with a charging coil. When the mobile phone is fixed by the annular bracket 4, the charging coil can charge the electronic device placed on the bracket 4. A solar panel 41 may also be provided in the middle of the annular bracket 4 or on the base 1. The electricity produced by the solar panel 41 can be stored and then used to power the exhaust device 3, or to charge electronic devices through the charging coil.
[0056] In some embodiments, please refer to Figure 1-Figure 5 The air extraction device 3 further includes an activation element 5, which can be disposed within the adsorption member 2 to activate the air extraction device 3 upon detecting contact between the adsorption member 2 and the wall. For example, the activation element 5 can be a travel switch, a photoelectric sensor switch, a distance detection switch, etc. In other embodiments, the activation element 5 can be disposed on the base 1, and the user manually operates the activation element 5 to activate or deactivate the air extraction device 3.
[0057] The following describes an embodiment of the adsorption member of the present invention.
[0058] The adsorption member in this embodiment has the same structure as the adsorption member 2 in the adsorption device in any of the above embodiments, and will not be described in detail here.
[0059] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
