Description

Technical Field

[0001] This utility model relates to the technical field of suction cups for support frames, and more particularly to an suction cup structure. Background Technology

[0002] When existing mobile phone or tablet stands are placed directly on a table, it is difficult to ensure the stability of the stand. Therefore, it is necessary to set an adsorption plate structure on the bottom support surface of the stand, and fix it to the surface of the table or the interior of the vehicle through the adsorption plate structure.

[0003] Currently, most suction cup structures require the user to apply a certain amount of force to the suction cup when it is attached to the bonding surface. This increases the negative pressure inside the suction cup, allowing it to adhere firmly to the surface. This process is mostly manual and quite cumbersome. Because it is done by pressing, the force distribution on the suction cup is uneven, making it difficult for this type of suction cup to adhere stably to the bonding surface. Utility Model Content

Therefore, they should not be construed as limitations on this application.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0040] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0041] In order to solve the technical problem that the existing technology usually relies on the user to press manually, which results in poor uniformity of pressure during the pressing process, and therefore the suction cup 4 of this type of suction cup structure is difficult to stably adhere to the bonding surface, this utility model embodiment provides an suction cup structure.

[0042] The following describes in detail the specific structure of an adsorption disk structure provided by an embodiment of this utility model. Figure 1-6 As shown, the specific structure of the suction cup includes an outer shell 1, a lifting assembly 2, a driving assembly 3, and a suction cup 4.

[0043] An installation cavity 11 is provided inside the outer shell 1; a limiting groove 12 is provided through the cavity wall of the installation cavity 11.

[0044] Specifically, the mounting cavity 11 inside the outer casing 1 is used to accommodate the lifting assembly 2 and the drive assembly 3, which can protect the lifting assembly 2, drive assembly 3, and other components, ensuring that these components can operate stably and preventing external objects from colliding with them and causing damage. It should be understood that the outer casing 1 of this embodiment can be detachably or fixedly mounted to the support frame of the electronic device. For example, the top of the outer casing 1 can be detachably mounted to the bottom of the support frame. When it is fixedly adsorbed onto the surface of the table by the suction cup 4, the outer casing 1 is used to fix the entire support frame in its current position.

[0045] according to Figures 2-3 As shown, the lifting assembly 2 includes a rotating base 21 and a connecting member 22. The rotating base 21 is rotatably disposed within the mounting cavity 11, and a rotating cavity extends through the rotating base 21. The cavity wall of the rotating cavity is provided with a height guide ramp 211. The connecting member 22 extends into the rotating cavity, and a support shaft is provided on the outer side wall of the connecting member 22, which abuts against the height guide ramp 211. The driving assembly 3 slides through the limiting groove 12 and is connected to the outer side wall of the rotating base 21.

[0046] Specifically, when the user attaches the bottom surface of the suction cup 4 to the attachment surface of the desktop or other attachment surfaces, the user can manually push the driving component, that is, push the driving component to move along one end of the limiting groove 12, so that the rotating seat 21 rotates circumferentially (clockwise) within the mounting cavity 11. Since a height guide ramp 211 is provided on the cavity wall of the rotating cavity, the upper part of the connector 22 is located within the rotating cavity, and the support shaft on the outside of the connector 22 abuts against the upper surface of the height guide ramp 211. Specifically, the height guide ramp gradually rises from one end to the other. Therefore, when the rotating seat 21 rotates, it drives the height guide ramp to rotate as well, so that the support shaft, while abutting the surface of the height guide ramp 211, can gradually rise and move. During this process, the support shaft drives the entire connector 22. As the device moves upward, the suction cup 4 located at the bottom of the connector 22 deforms, allowing it to be fixedly attached to the surface of the bonding surface, preventing the entire support frame from easily shaking. Conversely, when the user needs to separate the bottom surface of the suction cup 4 from the bonding surface, the driving component is pushed to move along the other end of the limiting groove 12, causing the rotating seat 21 to rotate circumferentially (counterclockwise) within the mounting cavity 11. This causes the height guide slope located on the wall of the rotating cavity to rotate accordingly. At this time, the connector 22 located in the rotating cavity moves gradually downward along the upper surface of the height guide slope via the support shaft, causing the suction cup 4 located at the bottom of the connector to gradually return to its original shape. Once the pressure difference (i.e., negative pressure) of the gas inside the suction cup 4 gradually decreases, the bottom surface of the suction cup 4 can be separated from the bonding surface. With this design, the user does not need to apply much force to the entire suction cup structure. They only need to manually push the drive component so that the rotating base 21 can drive the connecting component 22 to gradually rise during rotation, so that the bottom surface of the suction cup 4 can be fixedly attached to the bonding surface, preventing the support frame set on the suction cup 4 structure from easily shaking, thus improving the user experience.

[0047] according to Figure 1 and Figure 6 As shown, the suction cup 4 is located at the bottom of the outer shell 1, and the top of the suction cup 4 is connected to the bottom of the connector 22; the bottom surface of the suction cup 4 is recessed with an air pressure chamber.

[0048] Specifically, when the bottom of the suction cup 4 is placed on the bonding surface, a closed space is formed between the air pressure chamber and the bonding surface. Therefore, when the suction cup 4 rises and moves under the action of the connecting piece 22, the entire suction cup 4 deforms. At this time, a negative pressure is formed inside the air pressure chamber, and the air pressure inside the air pressure chamber will be higher than the external atmospheric pressure. This results in a pressure difference between the suction cup 4 and the surface of the bonding surface it contacts, thereby generating an adsorption force that allows the suction cup 4 to adhere tightly to the bonding surface, ensuring a tight fit between the suction cup 4 and the bonding surface. This prevents the suction cup 4 from becoming misaligned or shaking. Conversely, when the suction cup 4 moves up and down under the action of the connector 22, it restores the original shape of the suction cup 4 before deformation. At this time, when the volume of the gas inside the suction cup 4 increases to a certain extent, the external environment and the pressure inside the suction cup 4 are balanced. The pressure inside the suction cup 4 is close to the external atmospheric pressure. The original pressure difference (i.e., negative pressure) gradually decreases. Eventually, because the adsorption force is no longer sufficient to maintain a stable adsorption state on the bonding surface, the suction cup 4 is no longer tightly attached to the bonding surface, and the user can separate the suction cup 4 from the bonding surface.

[0049] It should be understood that the suction cup 4 in this embodiment of the present invention is a silicone suction cup 4, specifically made of silicone material.

[0050] according to Figure 4 As shown, in some specific embodiments, the bottom surface of the mounting cavity 11 has a positioning port 111, and the bottom of the connector 22 passes through the positioning port 111 and then connects to the top of the suction cup 4.

[0051] Specifically, the positioning port 111 located on the bottom surface of the mounting cavity 11 is used to ensure that the axis of the connector 22 is aligned with that of the suction cup 4, preventing positional deviation between the two from affecting the adsorption effect. More specifically, each outer side of the connector 22 abuts against each side wall of the positioning port 111. In this way, when the suction cup 4 is tightly pressed against the mating surface, the entire connector 22 can be prevented from shaking. When the bottom of the connector 22 passes through the positioning port 111 and connects with the suction cup 4, it is constrained in the radial direction, which can prevent it from shifting in the lateral direction. This restricts the degree of freedom of the connector 22, ensuring that it can only move in the vertical direction and reducing strong shaking caused by external forces.

[0052] according to Figure 4 As shown, in a further embodiment, the sidewall of the positioning port 111 is formed with a first straight surface 112, and the outer sidewall of the connector 22 is formed with a second straight surface for engaging with the first straight surface 112.

[0053] Specifically, when the second straight surface on the outer side wall of the connector 22 is fully fitted with the first straight surface 112 on the side wall of the positioning port 111, the two form a near-zero gap geometric constraint relationship. Through the rigid contact between the two, that is, through the contact between the first straight surface 112 and the second straight surface, external forces (such as vibration and impact) can be more evenly distributed to the entire contact surface, making the contact stress distribution of the two contact surfaces more uniform, reducing the gap expansion caused by local wear, and effectively suppressing the displacement of the connector 22 in other directions (such as radial or lateral), thereby avoiding the situation where the connector 22 shakes due to the gap between the two during assembly or use, so that the connector 22 can be fixed in the radial, lateral or circumferential directions.

[0054] It is understandable that the sidewall of the positioning port 111 is symmetrically formed with two first straight surfaces 112, and the outer sidewall of the connector 22 is symmetrically provided with two second straight surfaces, each of which is respectively attached to each of the first straight surfaces 112. By having the first straight surfaces 112 arranged on both sides symmetrically attached to the second straight surfaces arranged on both sides, the load can be evenly transmitted when they are in contact, thereby improving the stability of the connector 22. Moreover, by having the first straight surfaces 112 on both sides contact the second straight surfaces on both sides, the load is evenly distributed, avoiding excessive stress concentration due to single-sided contact, which could lead to wear or deformation of the connector 22.

[0055] according to Figure 2 As shown, in some specific embodiments, the drive assembly 3 includes a pusher 31 and a moving member 32. One end of the moving member 32 is connected to the outer wall of the rotating seat 21. The pusher 31 is provided with a connecting part 33, which is movably inserted through the limiting groove 12 and connected to the outer wall of the moving member 32.

[0056] Specifically, in this embodiment of the invention, the user only needs to manually push the pusher 31 to make the rotating seat 21 rotate a certain range around its circumference. For example, when the connecting part 33 is close to one end of the limiting groove 12, if the user pushes the pusher 31 along the other end of the limiting groove 12, the connecting part 33 will slide in the limiting groove 12, forcing the moving part 32 to move in the direction of movement of the connecting part 33, that is, to move along the geometric path of the limiting groove 12. In this process, the moving part 32 applies a force to the rotating seat 21 to make it rotate around its circumference, so that the rotating seat 21 rotates a certain range around its circumference, causing the connecting part 22 to rise or fall a certain distance.

[0057] according to Figure 3 As shown, in a further embodiment, a first limiting part 13 and a second limiting part 14 for limiting the movement range of the moving member 32 are provided at intervals in the mounting cavity 11.

[0058] Specifically, in order to limit the lifting range of the connector 22 and prevent the suction cup 4 from exceeding the specified deformation, a first limiting part 13 and a second limiting part 14 are provided at intervals on the bottom surface or inner wall of the mounting cavity 11, so that the moving part 32 can only move between the first limiting part 13 and the second limiting part 14, thereby limiting the lifting range of the connector 22.

[0059] For example, when the connecting part 33 is close to one end of the limiting groove 12, the pushing member 31 abuts against the first limiting part 13. If the user pushes the pushing member 31 along the other end of the limiting groove 12 until the moving member 32 moves to abut against the second limiting part 14, the second limiting part 14 prevents the moving member 32 from moving further. At this time, under the action of the height guide ramp 211 of the rotating seat 21, the connecting member 22 can be raised to the specified height and then fixed, so that the degree of deformation of the suction cup 4 can be fixed. It adheres to the bonding surface; conversely, when the pushing member 31 is reset and moved until the moving member 32 moves to abut against the first limiting part 13, the first limiting part 13 is used to prevent the moving member 32 from moving further. Similarly, under the action of the height guide ramp 211 of the rotating seat 21, the connecting member 22 can be lowered to the specified height and then fixed so that the suction cup 4 can return to its original shape. With this setting, the connecting member 22 can be accurately raised or lowered to the specified height and fixed, thereby ensuring the stability of the deformation and recovery state of the suction cup 4.

[0060] In some specific embodiments, the bottom of the rotating seat 21 is provided with an annular protrusion, which abuts against the bottom surface of the mounting cavity 11.

[0061] Specifically, when the rotating seat 21 rotates, the annular protrusion at its bottom slides against the bottom surface of the mounting cavity 11. Since the contact area between the annular protrusion and the bottom surface of the mounting cavity 11 is small, the friction area between the rotating seat 21 and the bottom surface of the mounting cavity 11 can be significantly reduced, thereby improving the smoothness of the entire rotating seat 21 during rotation.

[0062] This can be understood as the annular protrusion having a semi-circular cross-section, which further reduces the contact area between the annular protrusion and the bottom surface of the mounting cavity 11.

[0063] according to Figure 3 and Figure 5 As shown, in some specific embodiments, two height guide ramps 211 are provided, and the two height guide ramps 211 are mirror images of the cavity wall of the rotating cavity; two support shafts are provided, and the two support shafts are respectively provided on the two side walls of the connector 22, and each support shaft abuts against each height guide ramp 211.

[0064] Specifically, two support shafts abut against the surfaces of two height guide ramps 211 respectively, so that the connector 22 can be stably positioned within the rotating cavity. When the rotating seat 21 rotates, the first support shaft gradually rises or falls against the surface of the first height guide ramp 211, and the second support shaft gradually rises or falls against the surface of the second height guide ramp 211. This arrangement can provide sufficient support for the connector 22 during the rotation of the rotating seat 21, that is, to keep the connector 22 balanced within the rotating cavity. It ensures that when each support shaft rises or falls against the surface of each height guide ramp 211, it can stably drive the connector 22 to rise or fall with each support shaft, while ensuring that the connector 22 will not tilt or lose balance.

[0065] It should be understood that each height guide ramp 211 in this embodiment of the present invention is arc-shaped. This arrangement can provide a smooth upward or downward path for the support shaft, ensuring that the support shaft can smoothly fit against the surface of the height guide ramp 211, and preventing the rotating cavity of the rotating seat 21 from abutting against each support shaft during rotation, which would prevent the rotating seat 21 from rotating.

[0066] according to Figure 5 As shown, it can be understood that the guiding surface of the height guide ramp 211 in this embodiment of the present invention includes an integrally formed first plane 2111, a curved surface 2112, and a second plane 2113.

[0067] In the aforementioned scenario, when the connecting member 22 needs to be moved upwards, the support shaft is located on the inclined second plane 2113. Since the curved surface 2112 gradually rises from one end to the other, the support shaft can conform to the curved surface 2112. As the rotating seat 21 rotates circumferentially, the support shaft gradually rises and moves while conforming to the curved surface 2112 until it conforms to the first plane 2111. The curved surface 2112 guides the support shaft to the first plane 2111, causing the connecting shaft to rise to a specified height. At this point, the suction cup 4 deforms. When it is necessary to move the connecting member 22 downward, the support shaft is located on the first plane 2111 and is attached to the surface of the first plane 2111. When the rotating shaft rotates along its circumference (opposite direction), the support shaft falls onto the second plane 2113 under the guidance of the curved surface 2112, and gradually moves downward to the specified height, so that the suction cup 4 gradually returns to its original shape during the process. Thus, it can be seen that the support shaft, under the guidance of the first plane 2111, the curved surface 2112 and the second plane 2113, enables the connecting member 22 to rise or fall smoothly.

[0068] according to Figure 1 and Figure 5As shown, in some specific embodiments, the mounting cavity 11 is provided with a connecting post 15 and a cover plate 16 for detachable connection with the support frame of the electronic device. The connecting post 15 has a fixing hole 151 and the cover plate 16 has a locking hole 161. The adsorption plate structure also includes a locking member, which is inserted into both the locking hole 161 and the fixing hole 151.

[0069] Specifically, to improve the ease of assembly or disassembly of the cover plate 16, when assembling the cover plate 16, it is only necessary to connect the locking hole 161 on the cover plate 16 with the fixing hole 151 on the connecting post 15, and then insert the locking member into both the locking hole 161 and the fixing hole 151 to fix the cover plate 16 in the mounting cavity 11 of the outer shell 1. This arrangement improves the ease of assembly between the cover plate 16 and the outer shell 1 and prevents the cover plate 16 from easily falling off. Conversely, when disassembling the cover plate 16, it is only necessary to disengage the locking member from both the fixing hole 151 and the locking hole 161 to remove the cover plate 16.

[0070] The foregoing can be understood as follows: the locking element is a bolt, and both the fixing hole 151 and the locking hole 161 are threaded holes. By inserting the bolt into each threaded hole, it is difficult for the bolt to loosen or fall off, so that the cover plate 16 is fixedly installed in the mounting cavity 11, thereby improving the firmness of the cover plate 16.

[0071] The aforementioned cover plate 16 can be installed on the support frame of the electronic device by means of snap-fit ​​or thread connection, and the specific type is not limited here.

[0072] An elastic element, which can be understood as a spring, is provided between the top surface of the suction cup 4 and the bottom surface of the outer shell 1. When the connecting member 22 moves upward, it causes the suction cup 4 to deform. During this deformation, the suction cup 4 applies pressure to the elastic element, causing it to be compressed. When the connecting member 22 moves downward, the suction cup 4 gradually returns to its original shape. At this time, because the elastic element is also returning to its original shape, a thrust is generated to push the suction cup 4 downward, so that the suction cup 4 can quickly return to its original shape.

[0073] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
