Description

Technical Field

[0001] This application relates to the field of mobile device holder technology, specifically to a suction cup assembly and a portable mobile device holder. Background Technology

[0002] The fixing principle of suction cup mobile device holders mainly relies on the vacuum negative pressure formed between the suction cup and the supporting surface, which is then used to achieve adsorption through atmospheric pressure. This structure has extremely high requirements for the flatness and smoothness of the supporting surface, and can only maintain a stable adsorption effect on smooth and hard surfaces such as glass and ceramic tiles.

[0003] However, in practical applications, the surfaces on which the suction cups are mounted are not ideally smooth. For example, in a vehicle environment, users want to fix mobile devices to the vehicle body using a mobile device holder. However, automotive interior surfaces (such as leather dashboards) may have a high degree of roughness, making it difficult for the suction cup edges to fully adhere to the uneven surface. This results in a significant decrease in sealing performance, allowing air to easily seep in through gaps, rapidly degrading the vacuum pressure, and causing the suction cups to frequently detach, severely impacting reliability. Especially in vehicle scenarios, vibrations during vehicle movement further exacerbate this risk of detachment, making it difficult to meet the requirement for stable mounting. Utility Model Content

[0004] This application provides a suction cup assembly and a portable mobile device holder, which can solve the problem of high roughness requirements for the bearing surface of suction cup mobile device holders.

[0005] To address the aforementioned technical problems, this application provides a suction cup assembly, comprising a suction cup body, a first magnetic component, a smooth base, and an adhesive component. The first magnetic component is mounted on the suction cup body; the smooth base is disposed on the suction cup body, and the smooth base and the first magnetic component are magnetically attracted to each other, forming a vacuum negative pressure cavity between the smooth base and the suction cup body; the adhesive component is bonded to the side of the smooth base opposite to the suction cup body, and is used to adhere the smooth base to a bearing surface, wherein the deformation capacity of the adhesive component is greater than that of the suction cup body.

[0006] In one embodiment, the surface roughness Ra of the smooth base facing the suction cup body is ≤3.2μm.

[0007] In one embodiment, the suction cup body has a middle portion and an edge portion, the edge portion being located on the outer periphery of the middle portion, a first magnetic element being mounted on the edge portion, and the middle portion being used to form a vacuum negative pressure cavity between itself and a smooth base.

[0008] In one embodiment, a first mounting groove is provided on the surface of the edge portion facing the smooth base, and at least a portion of the first magnetic element is fixed in the first mounting groove.

[0009] In one embodiment, the edge portion has a sealed first mounting cavity, the first magnetic element is located in the first mounting cavity, and the cavity wall of the first mounting cavity surrounds the outer periphery of the first magnetic element.

[0010] In one embodiment, the smooth base is configured as iron or a magnet.

[0011] In one embodiment, the smooth base includes a smooth base body and a second magnetic element, the second magnetic element being mounted on the smooth base body and magnetically attracted to the first magnetic element.

[0012] In one embodiment, a second mounting groove is provided on the surface of the smooth base body facing the suction cup body, and at least a portion of the second magnetic element is fixed in the second mounting groove; or, the smooth base has a sealed second mounting cavity, and the second magnetic element is located in the second mounting cavity.

[0013] In one embodiment, the suction cup assembly further includes a rotating component and a lifting component. The lifting component is connected to the end of the middle portion that is away from the smooth base. When the rotating component rotates relative to the lifting component in a first direction, the lifting component can lift the middle portion to form a vacuum negative pressure cavity between the middle portion and the smooth base. When the rotating component rotates relative to the lifting component in the opposite direction of the first direction, the lifting component can lower the middle portion to release the negative pressure of the vacuum negative pressure cavity.

[0014] To address the aforementioned technical problems, this application provides a portable mobile device holder, including a suction cup assembly and a fixing member. The suction cup assembly is the suction cup assembly involved in any of the above embodiments; the fixing member is connected to the suction cup body and is used to fix the mobile device.

[0015] In the suction cup assembly of this application, the smooth base provides a smooth contact surface for the suction cup body. Compared to the suction cup body directly adsorbing onto a rough bearing surface, this significantly reduces the gap between the suction cup body and its contact surface, ensuring the sealing of the vacuum negative pressure chamber, reducing the risk of negative pressure failure caused by air infiltration, and making the negative pressure adsorption effect more stable and durable. By setting a smooth base and an adhesive component, the adhesive component is attached to the bearing surface, allowing the suction cup body to be set on the bearing surface through the smooth base and adhesive component. Due to the stronger deformation capability of the adhesive component, when in contact with a bearing surface with high roughness, the adhesive component fills the uneven texture of the bearing surface through a greater degree of self-deformation, forming a tightly fitted fixed structure, solving the problem of frequent detachment of traditional suction cups due to their inability to adapt to rough surfaces. This suction cup assembly retains the convenience of suction cup negative pressure adsorption, and overcomes the dependence on the smoothness of the bearing surface through the characteristics of the adhesive component, significantly improving the fixation stability of the suction cup assembly in complex surface environments. Furthermore, the magnetic adsorption between the smooth base and the suction cup body creates a linkage structure between the suction cup body and the smooth base. When the suction cup assembly is subjected to external forces such as pulling or shaking, the two are less likely to undergo relative displacement, thus avoiding damage to the negative pressure cavity caused by misalignment. This enhances the overall anti-drop performance, and is particularly effective in scenarios with continuous vibration, such as in vehicles. Attached Figure Description

[0029] Please refer to Figure 1-3 As shown, this application provides a suction cup assembly 10, which is applied to a portable mobile device holder to fix the mobile device to a support surface.

[0030] The suction cup assembly 10 includes a suction cup body 11, a first magnetic element 12, a smooth base 13, and an adhesive element 14. The suction cup body 11 is typically flexible and deformable; for example, it can be made of silicone. The suction cup body 11 is generally disc-shaped. The first magnetic element 12 is mounted on the suction cup body 11 and can be, for example, a magnet. The first magnetic element 12 is fixed to the suction cup body 11 to prevent relative separation and movement.

[0031] A smooth base 13 is disposed on the suction cup body 11. In one embodiment, the surface roughness Ra of the smooth base 13 facing the suction cup body 11 is ≤3.2μm, that is, the surface of the smooth base 13 that is in contact with the suction cup body 11 is a smooth surface. Preferably, the surface of the smooth base 13 facing the suction cup body 11 is a smooth plane. The smooth base 13 is magnetically attracted to the first magnetic element 12, so that a stable bonding pressure is formed between the suction cup body 11 and the smooth base 13, ensuring that the contact edges of the two are in close contact. Furthermore, the magnetic attraction has a self-aligning characteristic, and the suction cup body 11 and the smooth base 13 can be quickly bonded without precise alignment during installation.

[0032] The smooth base 13 is used to form a vacuum negative pressure cavity 15 between itself and the suction cup body 11. Specifically, in one embodiment, the suction cup body 11 has a middle portion 111 and an edge portion 112. The edge portion 112 is located on the outer periphery of the middle portion 111, and a first magnetic element 12 is installed on the edge portion 112. The middle portion 111 is used to form a vacuum negative pressure cavity 15 between itself and the smooth base 13. When the edge portion 112 of the suction cup body 11 is magnetically attracted to the smooth base 13, the middle portion 111 can be lifted to form a vacuum negative pressure cavity 15 between itself and the smooth base 13. In other embodiments, when the edge portion 112 of the suction cup body 11 is magnetically attracted to the smooth base 13, the middle portion 111 and the smooth base 13 can directly form a cavity. A vacuum evacuation component can be used to evacuate the cavity, thereby forming a vacuum negative pressure cavity 15.

[0033] The adhesive component 14 is bonded to the smooth base 13 on the side opposite to the suction cup body 11. The adhesive component 14 is used to adhere the smooth base 13 to the bearing surface, and the deformation capacity of the adhesive component 14 is greater than that of the suction cup body 11. For example, the adhesive component 14 can be a soft pressure-sensitive adhesive, such as acrylic pressure-sensitive adhesive, rubber-based pressure-sensitive adhesive, etc., or it can also be an elastic hot melt adhesive. The adhesive component 14 is usually a soft gel, and its deformation capacity is significantly greater than that of the suction cup body 11. In some embodiments, the Shore hardness of the adhesive component 14 is A10°-A50°, and the Shore hardness of the suction cup body 11 is A60°-A90°.

[0034] In the suction cup assembly 10 of this application, the smooth base 13 provides a smooth contact surface for the suction cup body 11. Compared to the suction cup body 11 being directly adsorbed onto a rough bearing surface, this significantly reduces the gap between the suction cup body 11 and its contact surface, ensuring the sealing of the vacuum negative pressure chamber 15, reducing the risk of negative pressure failure caused by air infiltration, and making the negative pressure adsorption effect more stable and durable. By setting the smooth base 13 and the adhesive 14, the adhesive 14 is adhered to the bearing surface, allowing the suction cup body 11 to be set on the bearing surface through the smooth base 13 and the adhesive 14. Due to the stronger deformation capability of the adhesive 14, when in contact with a bearing surface with higher roughness, the adhesive 14 fills the uneven texture of the bearing surface through a greater degree of self-deformation, forming a tightly fitted fixed structure, solving the problem of traditional suction cups frequently falling off due to their inability to match rough surfaces.

[0035] The suction cup assembly 10 retains the convenience of suction cup negative pressure adsorption, while overcoming the dependence on the smoothness of the bearing surface through the characteristics of the adhesive 14, significantly improving the fixation stability of the suction cup assembly 10 in complex surface environments. Furthermore, the magnetic adsorption between the smooth base 13 and the suction cup body 11 creates a linked structure between them. When the suction cup assembly 10 is subjected to external forces such as pulling or shaking, the two are less likely to experience relative displacement, avoiding damage to the negative pressure cavity due to misalignment, thereby enhancing the overall anti-detachment performance, especially effective in scenarios with continuous vibration, such as in vehicles.

[0036] In one embodiment, such as Figure 4 As shown, a first mounting groove 1121 is provided on the surface of the edge portion 112 facing the smooth base 13. At least a portion of the first magnetic component 12 is fixed within the first mounting groove 1121. Preferably, the first mounting groove 1121 is adapted to the shape and size of the first magnetic component 12, and the surface of the first magnetic component 12 facing the smooth base 13 is flush with the opening of the first mounting groove 1121. The first mounting groove 1121 can provide a positioning constraint for the first magnetic component 12, preventing the magnetic component from shifting during assembly or use, and ensuring that it always maintains a preset corresponding adsorption position with the smooth base 13.

[0037] In one embodiment, such as Figure 5 As shown, the edge portion 112 has a sealed first mounting cavity, and the first magnetic component 12 is located inside the first mounting cavity. The cavity wall of the first mounting cavity surrounds the outer periphery of the first magnetic component 12. The sealed first mounting cavity forms a comprehensive enclosure and constraint on the first magnetic component 12 through the cavity wall, which can effectively prevent the magnetic component from shifting, shaking, or falling off due to vibration, external pressure, or deformation of the suction cup body 11 during use, ensuring that the magnetic component is always in the preset position and guaranteeing the accuracy and stability of magnetic adsorption with the smooth base 13. Compared with exposed installation, the first mounting cavity completely houses the first magnetic component 12. The cavity wall of the sealed mounting cavity can fill the gap between the magnetic component and the suction cup body 11, preventing the gap formed by the installation of the magnetic component from becoming a leakage channel of the vacuum negative pressure cavity 15. At the same time, the enveloping structure can ensure that the surface of the edge portion 112 facing the smooth base 13 remains continuously flat, so that the suction cup body 11 and the smooth base 13 form a complete sealing surface when they are attached, further enhancing the airtightness of the vacuum negative pressure cavity 15. The first mounting cavity can be integrally formed during the molding of the suction cup body 11. The magnetic components are fixed in the cavity by embedding or injection molding, without the need for additional fixing structures (such as adhesives). This improves assembly efficiency and avoids the problem of magnetic components loosening due to adhesive aging, thereby reducing production and maintenance costs.

[0038] In one embodiment, such as Figure 2 and Figure 3As shown, the smooth base 13 is configured as iron or a magnet, that is, the smooth base 13 itself is configured as a material that can be magnetically attracted to the first magnetic component 12. This reduces the number of parts, speeds up assembly, reduces production complexity, and saves the installation space of additional magnetic components. It also makes the overall thickness of the smooth base 13 thinner and the overall structure of the suction cup assembly 10 lighter and more compact. It avoids the loss of adsorption force caused by the assembly gap and position deviation between the additional magnetic component and the base, and can form a more stable magnetic circuit, ensuring that the adsorption force is evenly applied to the contact surface, thereby indirectly ensuring the sealing effect of the vacuum negative pressure cavity 15.

[0039] In one embodiment, such as Figure 6 and Figure 7 As shown, the smooth base 13 includes a smooth base body 131 and a second magnetic component 132. The second magnetic component 132 is mounted on the smooth base body 131 and magnetically attracted to the first magnetic component 12. In this embodiment, the material of the smooth base body 131 is not limited, and materials such as plastic with lower cost and no magnetic attraction can be selected, thereby reducing the overall cost.

[0040] In one embodiment, such as Figures 6-8 As shown, a second mounting groove 1311 is provided on the surface of the smooth base body 131 facing the suction cup body 11. At least a portion of the second magnetic component 132 is fixed within the second mounting groove 1311. Preferably, the shape and size of the second mounting groove 1311 are adapted to the second magnetic component 132, and the surface of the second magnetic component 132 facing the suction cup body 11 is flush with the opening of the second mounting groove 1311. The second mounting groove 1311 is disposed opposite to the first mounting groove 1121, such that the first magnetic component 12 and the second magnetic component 132 are disposed opposite to each other. The second mounting groove 1311 can provide a positioning constraint for the second magnetic component 132, preventing the magnetic component from shifting during assembly or use.

[0041] In one embodiment, such as Figure 5 As shown, the smooth base 13 has a sealed second mounting cavity, and the second magnetic component 132 is located in the second mounting cavity. The cavity wall of the second mounting cavity wraps around the outer periphery of the second magnetic component 132, so that the sealed second mounting cavity forms an all-round enclosure and constraint on the second magnetic component 132 through the cavity wall, which can effectively prevent the magnetic component from being displaced, shaking or falling off due to vibration, external force squeezing or deformation of the suction cup body 11 during use.

[0042] In one embodiment, such as Figure 1 and Figure 2As shown, the suction cup assembly 10 also includes a rotating member 16 and a lifting member 17. The lifting member 17 is connected to the end of the middle portion 111 that is away from the smooth base 13. The first direction is defined as the clockwise or counterclockwise direction of the circumferential direction of the suction cup body 11. When the rotating member 16 rotates relative to the lifting member 17 in the first direction, the lifting member 17 can drive the middle portion 111 to lift. Finally, as shown... Figure 3 and Figure 7 As shown, a vacuum negative pressure cavity 15 is formed between the middle part 111 and the smooth base 13; when the rotating part 16 rotates relative to the lifting assembly 17 in the opposite direction of the first direction, the lifting assembly 17 can drive the middle part 111 to descend, thereby releasing the negative pressure in the vacuum negative pressure cavity 15, and finally, as shown... Figure 2 and Figure 6 As shown, the negative pressure in the vacuum negative pressure cavity 15 between the middle part 111 and the smooth base 13 is released, making it easier for the user to remove the suction cup body 11. Specifically, the rotating part 16 may have a ramp, and the lifting assembly 17 includes a pin with its end located on the ramp. When the rotating part 16 rotates, the pin moves up or down on the ramp, causing the middle part 111, which is fixed relative to the pin, to move up or down.

[0043] like Figure 1 and Figure 2 As shown, this application provides a portable mobile device holder, which includes a suction cup assembly 10 and a fixing member 20. The suction cup assembly 10 is the suction cup assembly 10 involved in any of the above embodiments, and the fixing member 20 is connected to the suction cup body 11 and is used to fix the mobile device. For example, the fixing member 20 can be magnetically attached to the mobile device by installing a magnetic component. The fixing member 20 can also rotate relative to the suction cup body 11 to change the angle of the mobile device.

[0044] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
