In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in the utility model will not be described separately.

It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the corresponding schematic diagrams, which may or may not be the left and right directions in normal use.

The embodiment of the utility model provides a suction cup, which can be used to fix a bracket to a surface to be adsorbed, wherein the bracket can be used to support electronic devices such as mobile phones, tablets, readers, and displays. It should be noted that the application scenario type of the embodiment of the utility model does not limit the structure of the suction cup of the embodiment of the utility model.

As shown in Figures 1 and 2, the application of a suction cup in a bracket is used as an example for explanation, and the bracket includes a support frame 1 and a suction cup 2. The support frame 1 is used to support an object. The embodiment of the utility model does not limit the specific structure of the support frame 1. As long as the support frame 1 can be used to support electronic devices such as mobile phones, tablets, readers, and displays, the structure of the support frame 1 can be adaptively set according to specific application scenarios. The suction cup 2 is fixed to the support frame 1, and the suction cup 2 is fixed to the bottom of the support frame 1. The suction cup 2 is fixed to the bottom of the support frame 1 to achieve the fixation of the support frame 1 and the surface to be adsorbed. For example, when the bracket is in use, the support frame 1 is placed on a desktop as an example for explanation. By setting the suction cup 2 at the bottom of the support frame 1, the suction cup 2 can be firmly adsorbed on the desktop, thereby improving the stability of the connection between the support frame 1 and the desktop, and reducing the risk of the support frame 1 slipping relative to the desktop during use.

As shown in Fig. 3 to Fig. 5, the suction cup 2 in the embodiment of the utility model includes a main body 201 and a raised portion 202. The main body 201 has a flat area 21 and a bearing area 230. The bottom surface of the flat area 21 and the bottom surface of the bearing area 230 have a first relative height difference to form the depth L1 of the groove 23 of the main body 201. The raised portion 202 has a deformation area 22. The deformation area 22 is protruding relative to the flat area 21. The deformation area 22 is set as a flexible part. The deformation area 22 can be deformed under the action of external force. One end of the deformation area 22 is connected to the bearing area 230. The deformation area 22 has a first side surface 2201, a second side surface 2202 and a connecting area 2203. The connecting area 2203 connects the first side surface 2201 and the second side surface 2202. The connection area 2203 protrudes from the bottom surface of the flat area 21, and the deformation area 22 is arranged in an annular shape. It should be noted that the annular shape indicates that the deformation area 22 is surrounded by a closed loop structure, one end of the deformation area 22 is connected to the bearing area 230, and the other end of the deformation area 22 is a free end. The other end of the deformation area 22 is far from the surface of the bearing area 230 relative to one end. Under the action of external force, the deformation area 22 is deformed, so that the other end of the deformation area 22 moves toward the direction close to the surface of the bearing area 230, and the deformation area 22 is accommodated in the groove 23. The deformation area 22 is annular. It can also be understood that when the deformation area 22 is squeezed on the surface to be adsorbed (such as a desktop), the deformation area 22 is deformed by external force, and the air between the deformation area 22 and the desktop is discharged to form a negative pressure area, and the side of the deformation area 22 away from the desktop forms a positive pressure area. Due to the pressure difference formed on both sides of the deformation area, the adsorption force between the suction cup 2 and the desktop is formed. Improve the stability of the support frame 1.

It should be understood that compared with the conventional suction cup without the flattening area 21, the flattening area 21 disclosed in the present patent can achieve the flattening of the surface to be adsorbed by applying a certain external force to the flattening area 21, thereby making the deformation area 22 more easily and firmly adsorbed on the surface to be adsorbed. The conventional suction cup is only provided with the deformation area 22, so that when the surface to be adsorbed is relatively uneven, it is easy to cause the various suction points of the deformation area 22 to be unbalanced, thereby causing natural falling off.

An embodiment of the utility model provides a suction cup, which includes a main body and a raised portion, the main body having a flat area and a bearing area, the bottom surface of the flat area and the bottom surface of the bearing area having a first relative height difference to form the depth of the groove of the main body; the raised portion having a deformation zone, one end of the deformation zone being connected to the bearing area, the deformation zone having a first side surface, a second side surface and a connecting area connecting the first side surface and the second side surface, the connecting area protruding from the bottom surface of the flat area, the deformation zone being arranged in a ring shape, the deformation zone can move toward the surface to be adsorbed and be accommodated in the groove under the action of external force, the deformation zone forms a negative pressure on the surface to be adsorbed to adsorb the surface to be adsorbed. The embodiment of the utility model arranges the suction cup into a main body and a protruding portion, one end of the protruding portion is connected to the main body, and the deformation zone is arranged in a ring shape. The suction cup is used to be fixed on the surface to be adsorbed. During the adsorption process, the deformation zone is deformed by the action of external force, and the deformed deformation zone can be accommodated in the groove, so that the flat zone is in contact with the surface to be adsorbed, thereby improving the stability of the suction cup's adsorption, and under the action of external force, the suction cup can be disassembled relative to the surface to be adsorbed, thereby improving the flexibility of the suction cup.

The main body 201 and the protrusion 202 in the embodiment of the utility model can be integrally formed, for example, the main body 201 and the protrusion 202 are integrally formed by injection molding, and the main body 201 and the protrusion 202 are made of the same material. The main body 201 is a component with a larger surface area than the protrusion 202, and the main body 201 is adhered to the bottom of the support frame 1, which is conducive to improving the stability of the connection between the suction cup 2 and the support frame 1.

As shown in Figure 3, the bottom surface of the flat area and the bottom surface of the bearing area form a groove of the main body through a first relative height difference, wherein the deformation zone 22 is set to a closed-loop structure, and the corresponding bearing area is also set to a closed-loop groove 23 surrounding the deformation zone 22. The deformation zone 22 is deformed relative to the bearing zone 230 by an external force, and the other end of the deformation zone 22 can move relative to the end connected to the bearing zone 230, and the other end of the deformation zone 22 moves toward the direction of the surface close to the bearing zone 230. The deformed deformation zone 22 can be accommodated in the groove 23, so that when the deformation zone 22 is adsorbed on the desktop, the side of the flat area 21 away from the support frame 1 is in contact with the desktop. Compared with the situation where the deformation zone 22 protrudes from the flat area 21 after deformation, the embodiment of the utility model reduces the risk of the support frame 1 shaking relative to the desktop by accommodating the deformed deformation zone 22 in the groove 23, which is beneficial to improve the stability of the contact between the support frame 1 and the desktop, thereby improving the stability of the support frame 1 supporting electronic devices such as mobile phones, tablets, readers, and displays.

The embodiment of the utility model also provides a bracket, which includes a support frame and a suction cup, the support frame is used to support an object, the suction cup is fixed to the support frame, the suction cup includes a body and a protrusion, the body has a flat area and a bearing area, the protrusion has a deformation area, the deformation area is arranged in an annular shape, and one end of the deformation area is connected to the bearing area, the flat area is provided with a groove around the outer side of the deformation area, and the other end of the deformation area can move relative to the one end under the action of an external force to be accommodated in the groove. The embodiment of the utility model is to arrange the suction cup to be fixed to the body and the support frame, and the body and the support frame have a large contact area, which is conducive to improving the stability of the connection between the suction cup and the support frame, the deformation area is arranged in an annular shape, and the suction cup is used to adsorb the surface on which the bracket is placed. During the adsorption process, the deformation area is deformed by the action of an external force, and the deformed deformation area can be accommodated in the groove, so that the flat area is in contact with the surface on which the bracket is placed, thereby improving the stability of the bracket placement, and further improving the stability of the bracket supporting the electronic device, and under the action of an external force, the suction cup can be disassembled relative to the supported surface, thereby improving the flexibility of the bracket.

In some embodiments, as shown in FIG. 4 and FIG. 5 , the connection area 2203 and the bearing area 230 have a second relative height difference, wherein the second relative height difference represents the shortest distance from the connection area 2203 to the surface of the bearing area 230. The second height difference can be represented by L7 in FIG. 5 . The ratio of the second relative height difference L7 to the first relative height difference L1 in the embodiment of the utility model is greater than or equal to 2. Among them, the ratio of the second relative height difference to the first relative height difference can be used to characterize the amount of protrusion of the connection area 2203 relative to the flat area 21. The greater the ratio of the first relative height difference to the second relative height difference, the greater the amount of protrusion of the connection area 2203 relative to the flat area 21. The embodiment of the utility model is conducive to achieving a greater degree of deformation of the deformation area by limiting the degree of protrusion of the connection area 2203 relative to the flat area 21 to the range where the ratio of the first relative height difference to the second relative height difference is greater than 2, so as to provide sufficient adsorption force to the surface to be adsorbed, thereby improving the stability of the connection between the suction cup and the surface to be adsorbed.

In some embodiments, as shown in FIG. 4 and FIG. 5 , the depth L1 of the groove 23 is greater than or equal to the thickness L2 of the deformation zone 22, wherein the depth of the groove 23 can be understood as follows: the flat zone 21 has two opposite ends, one end of the flat zone 21 is fixed to the support frame 1, and the other end of the flat zone 21 is away from the bottom of the support frame 1, wherein the groove 23 is formed at the other end of the flat zone 21, and the opening of the groove 23 is located on the side of the flat zone 21 away from the support frame 1, and the depth of the groove 23 represents the distance from the opening end of the groove 23 to the bottom of the groove 23, and the direction of the depth is consistent with the direction of the opposite ends of the flat zone 21. Combined with FIG. 6 and FIG. 7 , the thickness L2 of the deformation zone 22 in the embodiment of the utility model is less than or equal to the depth L1 of the groove 23, so that the deformation zone 22 can be completely accommodated in the groove 23 in the depth direction after deformation, and will not protrude relative to the surface of the flat zone 21, so that the flat zone 21 can be fully fitted and contacted with the desktop without being affected by the deformation zone 22.

In some embodiments, in combination with FIG. 4 and FIG. 5 , the width L3 of the groove 23 is greater than or equal to the length L4 of the deformation zone 22. It should be noted that the width L3 of the groove 23 represents the width dimension of the groove 12 in the surface extension direction of the flat zone 21, and the length of the deformation zone 22 represents the length from one end of the deformation zone 22 connected to the flat zone 21 to the other end of the movable area. In the embodiment of the utility model, by making the width of the groove greater than or equal to the length of the deformation zone, when the deformation zone is deformed, the deformation zone can be completely accommodated in the groove in the length direction without forming curling or bulges outside the groove. When the deformation zone 22 is adsorbed on the desktop, the flat zone 21 can fully fit and contact with the desktop without being affected by the deformation zone, which is beneficial to improve the stability of the connection between the suction cup and the surface to be adsorbed.

In some embodiments, as shown in combination with FIG4 and FIG5, the protrusion 202 further includes a non-deformation area 24, and the non-deformation area 24 is formed inside the deformation area 22. It can be understood that the area inside the deformation area 22 is a plane area, and by providing the non-deformation area 24 inside the deformation area 22, it is beneficial to improve the adsorption stability of the suction cup and the surface to be adsorbed.

In some embodiments, as shown in FIG. 5 , the thickness L5 of the non-deformed region 24 is less than the thickness L6 of the flattened region 21 . Among them, the thickness direction of the non-deformation zone 24 is consistent with the thickness direction of the flat zone 21, and the thickness of the non-deformation zone 24 is thinner than the flat zone 21. When the deformation zone 22 is adsorbed on the desktop, the flat zone 21 is in contact with the desktop, while the non-deformation zone 24 cannot be in contact with the desktop, thereby reducing the contact area between the entire suction cup and the desktop. During the adsorption process, the air inside the deformation zone 22 needs to be discharged. If the air is not completely discharged, the remaining air is likely to slightly lift the suction cup, thereby making the suction stability of the suction cup and the desktop poor. In the present application, the non-deformation zone 24 inside the deformation zone 22 is set to be thinner than the flat zone 21. During the adsorption process, the inner side of the deformation zone 22 does not need to be completely in contact with the desktop. The deformation zone 22 only needs to be in contact with the desktop to achieve complete sealing between the inner and outer sides of the deformation zone 22. On the one hand, it saves the force of squeezing the suction cup to discharge the air inside the deformation zone during the adsorption process. On the other hand, it reduces the adsorption area and reduces the risk of residual air within the contact area, which is conducive to improving the stability of adsorption.

In some embodiments, as shown in FIG5 , the thickness L6 of the flattened area 21 is 0.2 mm to 0.5 mm greater than the thickness L5 of the non-deformed area 24. In the embodiment of the utility model, by making the thickness of the non-deformed area 24 slightly smaller than the thickness of the flattened area 21, the contact area between the suction cup and the surface to be adsorbed can be reduced, saving the extrusion force required to exhaust air, and the gap between the non-deformed area 24 and the surface to be adsorbed will not be too large, which is conducive to improving the stability of adsorption.

In some embodiments, as shown in FIG5 , the thickness L2 of the deformation zone 22 is greater than or equal to 0.2 mm and less than or equal to 0.6 mm. In the embodiment of the utility model, by setting the thickness L2 of the deformation zone 22 within a certain range, the deformation zone 22 is arranged on the flat zone 21 in a thin-edge shape, which is conducive to improving the flexibility of the deformation zone 22, facilitating the pressing of the deformation zone 22 on the surface to be adsorbed, and improving the stability of the adsorption of the deformation zone 22 and the surface to be adsorbed.

In some embodiments, as shown in FIG. 5 , the angle θ between the deformation zone 22 and the flattening zone 21 is greater than or equal to 30 degrees and less than or equal to 45 degrees. The angle between the deformation zone 22 and the flattening zone 21 represents the angle between the deformation zone 22 and the flattening zone 21 in a natural state. In the natural state, the deformation zone 22 is not affected by external forces, so that the deformation zone 22 extends naturally without deformation. Of course, it should be noted that the angle between the deformation zone 22 and the flattening zone 21 in the embodiment of the utility model may change with the increase in the number of uses. The angle θ defined in the embodiment of the utility model is the angle between the deformation zone 22 and the flattening zone 21 in the factory state, specifically the angle between the extension direction of the deformation zone 22 and the extension direction of the bottom surface of the flattening zone 21. It should be noted that the angle θ between the deformation zone 22 and the flat zone 21 in the embodiment of the utility model can be set to 30 degrees, 35 degrees, 40 degrees and 45 degrees, and the angle θ between the deformation zone 22 and the flat zone 21 can be set according to the size of the support frame. The embodiment of the utility model is conducive to improving the stability of the connection between the suction cup and the surface to be adsorbed by limiting the angle between the deformation zone 22 and the flat zone 21 within a certain range.

In some embodiments, the main body 201 and the raised portion 202 are provided with at least one parameter, that is, the main body 201 and the raised portion 202 can be provided with the same parameter specification or different parameter specifications, wherein the parameter includes one or more of hardness, thickness, and length; for example, the hardness of the main body 201 can be the same as that of the raised portion 202, or the hardness of the raised portion 202 is less than that of the main body 201, or the thickness of the main body 201 is equal to the thickness of the raised portion 202, or the thickness of the main body 201 is greater than the thickness of the raised portion 202. In some embodiments, the angle between the deformation zone 22 and the flattening zone 21 can be provided with different sizes. The size of the angle can be provided according to the specific actual application scenario of the suction cup.

In some embodiments, as shown in FIG8 , the deformation zone 22 in the embodiment of the utility model can be set to one or more of a circular ring, a square ring, and a diamond ring. In the embodiment shown in FIG8 , the deformation zone 22 is set to a square ring, and the shape of the deformation zone 22 can be adaptively set according to the shape structure of the bottom of the support frame, so as to improve the stability of the suction cup installed on the support frame. For example, when the bottom of the support frame is set to a circle, the deformation zone 22 can be set to a circular ring; when the bottom of the support frame is set to a triangle, the deformation zone 22 can be set to a triangular ring. The embodiment of the utility model does not limit the shape of the deformation zone 22.

In some embodiments, as shown in FIG. 8 , the deformation zone 22 has a first extension portion 224 that is relatively arranged in the front-to-back direction and a second extension portion 225 that is relatively arranged in the left-to-right direction, and the first extension portion 224 and the second extension portion 225 are connected to form a ring. It should be noted that the front-to-back, left-to-right, and right-to-left directions in the embodiments of the utility model are only used as the directions of the relative positions on the suction cup, and do not represent the front-to-back, left-to-right, and right-to-left directions relative to other reference objects in the absolute coordinate system. Among them, the deformation zone 22 is an annular structure, then there are two first extension portions 224 that are relatively arranged in the front-to-back direction, and there are also two second extension portions 225 that are relatively arranged in the left-to-right direction. The first extension portion 224 and the second extension portion 225 are sequentially connected to form a closed-loop deformation zone 22.

In some embodiments, as shown in FIG8 , the setting parameters of the first extension 224 are greater than the setting parameters of the second extension 225, wherein the setting parameters include hardness, thickness, length, and angle with the flat area. It should be noted that the setting parameters in the embodiment of the utility model represent the structural parameters and material parameters of the deformation zone. Among them, the hardness of the first extension 224 is greater than the hardness of the second extension 225, which means that the elasticity of the first extension 224 is less than the elasticity of the second extension 225. Then, there is a difference in elasticity between the first extension 224 in the front-to-back direction of the suction cup and the second extension 225 in the left-to-right direction, so that the suction force in the two directions is different. In the process of removing the suction cup adsorbed on the surface from the surface, due to the different suction forces in the two directions, the user can apply less external force to the suction cup in the front-to-back direction to achieve the removal of the suction cup. The thickness of the first extension 224 is greater than that of the second extension 225. The thinner the thickness, the stronger the deformation ability of the suction cup. Therefore, the second extension 225 is set to be thinner than the first extension 224. The user applies a small external force in the front and rear directions to make the first extension 224 detach from the desktop to achieve the removal of the entire suction cup. The larger the length, the greater the suction force. Therefore, the lengths of the first extension and the second extension are set to be inconsistent. The second extension can be detached from the desktop by a small force in the left and right directions, so that the suction cup can be removed. The angle between the suction cup and the flat area can also be set differently, and the suction force corresponding to different angles is also different. It should be understood that in the prior art, the traditional suction cup is non-directional. When the user needs to peel the suction cup off the adsorption surface, the suction force of the traditional suction cup in each direction is relatively balanced. Therefore, the user cannot easily peel the suction cup from the adsorption surface. For example, the user may be disorderly and apply a large external force to shake the suction cup in all directions to peel the suction cup. At this time, the user has done a lot of useless work and it is easy to shake the product attached to the suction cup. If the product attached to the suction cup is a mobile power supply, the user's vigorous shaking may cause poor contact of electronic components in the mobile power supply.

It is foreseeable that when the user needs to adjust the angle of the traditional suction cup, it needs to be peeled off from the adsorption surface and then re-adsorbed, and the user may need to repeat the peeling and adsorption actions many times to adjust to the angle that the user is satisfied with, which causes great inconvenience. In the suction cup of the utility model, when the setting parameters of the first extension part 224 of the suction cup are greater than the setting parameters of the second extension part 225, the setting parameters include hardness, thickness, length and angle with the flat area. It can be inferred that the suction force of the first extension part 224 and the second extension part 225 is unbalanced. Due to the unbalanced suction force of the first extension part 224 and the second extension part 225, the rotation of the suction cup on the adsorption surface is feasible. When adjusting the angle of the suction cup, the user does not need to peel the suction cup from the adsorption surface and readjust it, but can directly rotate the suction cup at the angle of adsorption, which is more convenient and faster than the traditional suction cup, and it is a linear angle adjustment.

The embodiment of the utility model differentiates the setting parameters of the first extension part arranged in the front-to-back direction and the second extension part arranged opposite to each other in the left-to-right direction, so that the suction forces exerted on the desktop by the first extension part and the second extension part are different. It is not easy to loosen by shaking in one direction, but it is easier to loosen by shaking in the other direction, thereby making it easy to lift the bracket from the desktop.

In some embodiments, as shown in FIG5 , the thickness L2 of the deformation zone 22 gradually decreases from one end connected to the bearing zone 230 to the other end. By reducing the thickness of the deformation zone 22 from one end to the other end, the embodiment of the utility model can maintain the stability of the suction cup adsorbed to the desktop and reduce the difficulty of the user to pick up the suction cup from the desktop.

In some embodiments, as shown in FIGS. 9-11 , a plurality of deformation zones 22 are provided, and a groove 23 is provided on the periphery of each deformation zone 22. It should be noted that the implementation of the utility model does not limit the number of deformation zones 22 provided. For example, the deformation zones 22 may be provided as 1, 2, 3, 4, 5, 6, etc. No matter how many deformation zones 22 are provided, the outer side of the deformation zone 22 is provided with a corresponding groove 23. The embodiment of the utility model also does not limit the form in which the deformation zone 22 is provided. For example, as shown in FIG. 9 , a plurality of deformation zones 22 may be provided in a concentrically spaced manner, or as shown in FIG. 10 , a plurality of deformation zones 22 may be provided in a matrix arrangement manner. The embodiment of the utility model is conducive to improving the stability between the suction cup and the surface to be adsorbed while reducing the difficulty of disassembling the suction cup and the surface to be adsorbed, thereby improving the convenience of use for users.

In some embodiments, the plurality of protrusions are provided with at least one specification setting parameter, the setting parameter including hardness, thickness, length, and the angle between the deformation zone and the flat zone. The setting parameters of each protrusion can be the same or different, and the setting method of the setting parameters of the plurality of protrusions can be set according to the arrangement method of the plurality of protrusions.

As shown in Fig. 9, multiple deformation zones 22 are arranged concentrically and spaced apart as an example, and the grooves 23 are also arranged concentrically. The geometric centers of the multiple deformation zones 22 coincide with each other, and the geometric center of the deformation zone 22 can coincide with the geometric center of the flat zone 21, which is conducive to improving the stability of the suction cup adsorption. In the embodiment shown in FIG. 9 , three deformation zones 22 are provided, each deformation zone 22 is provided with a groove 23 on its outer side, and each deformation zone 22 is provided with a non-deformation zone on its inner side (refer to the first non-deformation zone 241, the second non-deformation zone 242, and the third non-deformation zone 243 shown in FIG. 9 ). In some embodiments, the thickness of the non-deformation zone is less than the thickness of the flat zone 21. Correspondingly, the inner side of the outermost deformation zone 22 is provided with a first non-deformation zone 241, and the first non-deformation zone 241 may be provided with a groove 23 corresponding to the second deformation zone 22 from the outside to the inside, and the inner side of the second deformation zone 22 is provided with a second non-deformation zone 242, and the thickness of the second non-deformation zone 242 may be less than the thickness of the first non-deformation zone 241, and the second non-deformation zone 242 may be provided with a groove 23 corresponding to the third deformation zone 22 from the outside to the inside, and the inner side of the third deformation zone 22 is provided with a third non-deformation zone 243, and the thickness of the third non-deformation zone 243 may be less than the thickness of the second non-deformation zone 242. In the embodiment of the utility model, when the deformation zone is set to be multiple, the thickness of the non-deformation zone in each deformation zone is less than the thickness of the flat zone or the non-deformation zone outside the deformation zone, which is conducive to improving the stability of the adsorption of the multiple concentric deformation zones and the surface to be adsorbed. In some embodiments, each deformation zone is provided with a relative first extension in the front-to-back direction and a relative second extension in the left-to-right direction. The setting parameters of the first extension of the multiple deformation zones are the same, the setting parameters of the second extension of the multiple deformation zones are the same, and the setting parameters of the first extension of the same deformation zone are different from the setting parameters of the second extension. It should be noted that the setting parameters include hardness, thickness, length and angle with the flat zone, which are consistent with those described in the above embodiments. The embodiment of the utility model, by differentially setting the first extension and the second extension of the multiple concentric deformation zones, ensures the stability of the suction cup and the surface to be adsorbed while also reducing the difficulty of disassembling the suction cup and the surface to be adsorbed, thereby facilitating the convenience of user operation.

In some embodiments, as shown in FIG. 10 and FIG. 11 , a plurality of deformation zones (refer to the first deformation zone 221 and the second deformation zone 222 shown in FIG. 10 ) are arranged in a matrix. The matrix means that a plurality of deformation zones form rows in the left-right direction, a plurality of deformation zones form columns in the front-back direction, and a plurality of deformation zones are arranged in a certain arrangement pattern. The embodiment of the utility model arranges a plurality of deformation zones in the form of a matrix, which is conducive to improving the adsorption stability of the suction cup and the surface to be adsorbed, while reducing the difficulty of disassembling the suction cup relative to the adsorption surface.

In some embodiments, as shown in Figure 10, the setting parameters of multiple deformation zones in the same column are the same, and the setting parameters of multiple deformation zones in the same row decrease from the outside to the inside. The suction cup shown in Figure 10 is provided with 3*3 deformation zones, three deformation zones are set in one row, and three deformation zones are set in one column. There are a total of 9 deformation zones on the same suction cup, and a groove is provided on the outside of each deformation zone. The setting parameters of multiple deformation zones in the same column are the same. For the convenience of explanation, the deformation zones in Figure 10 are divided into a first deformation zone 221, a second deformation zone 222 and a third deformation zone 223 according to the number of columns. The first deformation zone 221 is all located in the same column, and the first deformation zone 221 is located at the leftmost side of each row. Multiple second deformation zones 222 are all located in the same column, and the second deformation zone 222 is located in the second one in each row. Multiple third deformation zones 223 are all in the same column, and the third deformation zone 223 is located in the third one in each row. Among them, the setting parameters of multiple first deformation zones 221 in the same column are the same, the setting parameters of multiple second deformation zones 222 in the same column are also the same, and the setting parameters of multiple third deformation zones 223 in the same column are also the same. From left to right in the same row are the first deformation zone 221, the second deformation zone 222 and the third deformation zone 223, and the setting parameters of different deformation zones in the same row are different. For example, the hardness of the first deformation zone 221 in the first row is greater than that of the second deformation zone 222, and the hardness of the second deformation zone 222 is less than that of the third deformation zone 223. The embodiment of the utility model is to set the setting parameters of multiple deformation zones arranged in a matrix in a manner that changes in the setting direction, which is conducive to ensuring the stability of the connection while being able to apply a small force in a specific direction to achieve the release of the connection state. Among them, the setting parameters include hardness, thickness, length and angle with the flat area. The embodiment of the utility model does not limit the specific form of the parameters that do not change between each deformation zone.

As shown in FIG. 11 , the sizes of the deformation zones arranged in a rectangular form may be different. The deformation zones located in the left and right columns are the first deformation zone 221 and the third deformation zone 223, respectively, and the deformation zone in the middle is the second deformation zone 222, wherein the setting parameters of the first deformation zone 221 and the third deformation zone 223 may be greater than the setting parameters of the second deformation zone 222. The forms of setting multiple deformation zones in the embodiment of the utility model include but are not limited to the above-described methods. In the case of setting multiple deformation zones, the setting parameters of the multiple deformation zones in the embodiment of the utility model may change according to the set rules to ensure the connection stability while increasing the difficulty of user disassembly.

The embodiment of the utility model further provides a suction cup, which includes a main body 201 and a raised portion 202, wherein the main body 201 has a flat area 21 and a bearing area 230, and the bottom surface of the flat area 21 and the bottom surface of the bearing area 230 have a first relative height difference to form the depth of the groove 23 of the main body 201; the raised portion 202 has a deformation area 22, one end of the deformation area 22 is connected to the bearing area 230, and the deformation area 22 has a first side surface 2201, a second side surface 2202, and a connecting area 2203 connecting the first side surface 2201 and the second side surface 2202, and the connecting area 2203 protrudes from the bottom surface of the flat area 21; the deformation area 22 The deformation zone 22 is arranged in a ring shape. Under the action of external force, the deformation zone 22 can move toward the surface to be adsorbed and be accommodated in the groove 23. The deformation zone 22 forms a negative pressure on the surface to be adsorbed to adsorb the surface to be adsorbed; wherein, the deformation zone 22 includes a first extension portion 224 arranged oppositely in the front-to-back direction and a second extension portion 225 arranged oppositely in the left-to-right direction, and the first extension portion 224 and the second extension portion 225 are connected to form a ring; the other end of the deformation zone 22 is deformed under the action of external force to be fixed to the surface to be adsorbed, and the absolute difference between the first air pressure difference between the inner and outer sides of the first extension portion 224 and the second air pressure difference between the inner and outer sides of the second extension portion 225 is greater than or equal to 0. In other words, the air pressure difference between the inner and outer sides of the first extension portion 224 and the second air pressure difference between the inner and outer sides of the second extension portion 225 can be the same or different. When the difference between the first air pressure difference between the inner and outer sides of the first extension part 224 and the second air pressure difference between the inner and outer sides of the second extension part is equal to 0, the first air pressure difference between the inner and outer sides of the first extension part is equal to the second air pressure difference between the inner and outer sides of the second extension part. When the difference between the first air pressure difference between the inner and outer sides of the first extension part 224 and the second air pressure difference between the inner and outer sides of the second extension part is greater than 0, it means that the inner and outer air pressure differences of the first extension part and the second extension part are different. Specifically, this can be achieved by differentially setting the setting parameters of the first extension part and the second extension part, and the above difference represents an absolute value. That is to say, the embodiment of the utility model does not limit whether the first air pressure difference is greater than or less than the second air pressure difference.

Under the action of external force, the deformation zone 22 is deformed, so that the other end of the deformation zone 22 moves toward the direction close to the surface of the flat zone 21. The deformation zone 22 is annular. It can also be understood that when the deformation zone 22 is squeezed on the surface to be adsorbed (such as a desktop), the deformation zone 22 is deformed by external force, and the air between the deformation zone 22 and the desktop is discharged to form a negative pressure zone. The side of the deformation zone 22 facing away from the desktop forms a positive pressure zone. Due to the pressure difference formed on both sides of the deformation zone, the adsorption force between the suction cup 2 and the desktop is formed. In the embodiment of the utility model, the air pressure difference between the inner and outer sides of the first extension part 224 is greater than the air pressure difference between the inner and outer sides of the second extension part 225. In the process of disassembling the suction cup relative to the surface to be adsorbed, a smaller force is applied to the second extension part in a specific direction, so that the suction cup can be disassembled, making it easy to loosen, reducing the difficulty of disassembling the bracket relative to the desktop, and improving the convenience of user operation.

In some embodiments, as shown in FIG8 , the setting parameters of the first extension portion 224 are greater than the setting parameters of the second extension portion 225, and the setting parameters include hardness, thickness, length, and angle with the flat area. It should be noted that the setting parameters in the embodiment of the utility model represent the structural parameters and material parameters of the deformation zone. Among them, the hardness of the first extension portion 224 is greater than the hardness of the second extension portion 225, which means that the elasticity of the first extension portion 224 is less than the elasticity of the second extension portion 225. Then, there is a difference in elasticity between the first extension portion 224 in the front-to-back direction of the suction cup and the second extension portion 225 in the left-to-right direction, so that the suction force in the two directions is different. In the process of removing the suction cup adsorbed on the surface from the surface, due to the different suction forces in the two directions, the user can apply less external force to the suction cup in the front-to-back direction to achieve the removal of the suction cup. The thickness of the first extension part 224 is greater than that of the second extension part 225. The thinner the thickness, the stronger the deformation ability of the suction cup. Therefore, the second extension part 225 is set to be thinner than the first extension part 224. The user applies a small external force in the front-to-back direction to make the first extension part 224 detach from the desktop to achieve the removal of the entire suction cup. The longer the length, the greater the suction force. Therefore, the lengths of the first extension part and the second extension part are set to be inconsistent. A small force can be applied in the left-right direction to make the second extension part detach from the desktop, so that the suction cup can be removed. The angle between the suction cup and the flat area can also be set differently, and the suction force corresponding to different angles is also different.

The embodiment of the utility model differentiates the setting parameters of the first extension part arranged in the front-to-back direction and the second extension part arranged opposite to each other in the left-to-right direction, so that the suction forces exerted on the desktop by the first extension part and the second extension part are different. It is not easy to loosen by shaking in one direction, but it is easier to loosen by shaking in the other direction, thereby making it easy to lift the bracket from the desktop.

In some embodiments, as shown in FIGS. 4 to 7 , a groove 23 is provided on the flat area 21 around the outer side of the deformation area 22, and the other end of the deformation area 22 can move relative to one end under the action of an external force to be accommodated in the groove 23. The embodiment of the utility model reduces the risk of the support frame 1 shaking relative to the desktop by accommodating the deformed deformation area 22 in the groove 23, which is conducive to improving the stability of the support frame 1 in contact with the desktop, thereby improving the stability of the support frame 1 supporting electronic devices such as mobile phones, tablets, readers, and displays.

In some embodiments, as shown in FIG5 , the depth L1 of the groove 23 is greater than or equal to the thickness L2 of the deformation zone, and the width L3 of the groove is greater than or equal to the length L4 of the deformation zone. The thickness L2 of the deformation zone 22 in the embodiment of the utility model is less than or equal to the depth L1 of the groove 23, so that the deformation zone 22 can be completely accommodated in the groove 23 in the depth direction after deformation, and will not protrude relative to the surface of the flat zone 21, so that the flat zone 21 can be fully in contact with the desktop without being affected by the deformation zone 22.

In some embodiments, as shown in FIG5 , the suction cup further includes a non-deformation zone 24, which is formed inside the deformation zone 22. The thickness L5 of the non-deformation zone 24 is less than the thickness L6 of the flat zone 21. On the one hand, the force of squeezing the suction cup to expel the air inside the deformation zone during the adsorption process is saved, and on the other hand, the adsorption area is reduced, reducing the risk of residual air within the contact area, which is conducive to improving the stability of adsorption.

In some embodiments, as shown in FIG5 , the thickness L5 of the flattened area 21 is 0.2 mm to 0.5 mm greater than the thickness L6 of the non-deformed area 24. In the embodiment of the utility model, by making the thickness of the non-deformed area 24 slightly smaller than the thickness of the flattened area 21, the contact area between the suction cup and the surface to be adsorbed can be reduced, saving the extrusion force required to exhaust air, and the gap between the non-deformed area 24 and the surface to be adsorbed will not be too large, which is conducive to improving the stability of adsorption.

In some embodiments, as shown in combination with FIG. 5 and FIG. 8 , the thickness of the first extension portion 224 is greater than or equal to 0.2 mm and less than or equal to 0.6 mm. In the embodiment of the utility model, by setting the thickness L2 of the deformation zone 22 within a certain range, the deformation zone 22 is arranged on the flat zone 21 in a thin-edge shape, which is conducive to improving the flexibility of the deformation zone 22, facilitating the pressing of the deformation zone 22 on the surface to be adsorbed, and improving the stability of the adsorption of the deformation zone 22 and the surface to be adsorbed.

In some embodiments, as shown in Figures 5 and 8, the angle θ between the first extension portion 224 and the flat area 21 is greater than or equal to 30 degrees and less than or equal to 45 degrees. The embodiment of the utility model limits the angle between the deformation area 22 and the flat area 21 within a certain range, which is conducive to improving the stability of the connection between the suction cup and the surface to be adsorbed.

In some embodiments, the deformation zone 22 can be configured in the shape of a circular ring, a square ring, or a diamond ring, or more.

In some embodiments, the thickness of the deformation zone 22 gradually decreases from one end connected to the flat zone 21 to the other end. By reducing the thickness of the deformation zone 22 from one end to the other end, the embodiment of the utility model can not only maintain the stability of the suction cup adsorbed to the desktop, but also help reduce the difficulty of the user to pick up the suction cup from the desktop.

In some embodiments, as shown in Figures 9 to 11, a plurality of deformation zones 22 are provided, and a groove 23 is provided on the periphery of each deformation zone 22. The embodiment of the utility model is conducive to improving the stability between the suction cup and the surface to be adsorbed while reducing the difficulty of disassembling the suction cup and the surface to be adsorbed by providing a plurality of deformation zones, thereby facilitating the convenience of use for users.

In some embodiments, as shown in FIG9 , a plurality of deformation zones 22 are arranged concentrically and spaced apart, and the grooves 23 are also arranged concentrically. The embodiment of the utility model arranges the first extension part and the second extension part of the plurality of concentric deformation zones differently, thereby ensuring the stability of the suction cup and the surface to be adsorbed and reducing the difficulty of disassembling the suction cup and the surface to be adsorbed, thereby facilitating the convenience of user operation.

In some embodiments, as shown in Figures 10 and 11, a plurality of deformation zones (refer to the first deformation zone 221 and the second deformation zone 222 shown in Figure 10) are arranged in a matrix. The embodiment of the utility model arranges a plurality of deformation zones in a matrix form, which is conducive to improving the adsorption stability of the suction cup and the surface to be adsorbed, while reducing the difficulty of removing the suction cup relative to the adsorption surface.
