Description

Technical Field

[0001] This application relates to the field of stent technology, and more particularly to a stent. Background Technology

[0002] Taking the application of brackets in automobiles as an example, in order to fix the brackets to the car's glass, some related technologies include brackets with suction cups. The suction cups are used to adhere to the glass, thereby fixing the brackets. When it is necessary to change the position of the brackets, the suction cups can be adjusted. However, frequent disassembly and reassembly of the suction cups will seriously affect their lifespan. Utility Model Content

[0003] In view of this, embodiments of this application aim to provide a bracket that helps extend the service life of the bracket's suction cup.

[0004] This application provides a bracket, including: A suction cup assembly includes a suction cup and a first connecting portion connected to each other. The suction cup has an adsorption surface, and the first connecting portion is disposed on the side of the suction cup opposite to the adsorption surface. The first connecting portion forms at least two slots, wherein the two slots are arranged opposite to each other along a first direction. A base assembly includes a base, a recovery structure, a drive structure, and at least two snap-fit ​​members, wherein the two snap-fit ​​members are disposed opposite each other along a first direction, the base has a receiving space, and the recovery structure, the drive structure, and the snap-fit ​​members are all disposed within the receiving space; The base assembly has a first state and a second state; In the first state, the base assembly and the suction cup assembly are docked along the second direction, the first connecting part is inserted into the receiving space, and the return structure is used to drive the two snap-fit ​​pieces to move closer to each other along the first direction, so that the two snap-fit ​​pieces are respectively partially snapped into the two slots, and the second direction is approximately perpendicular to the first direction; In the second state, the driving structure drives the two snap-fit ​​pieces to move away from each other along a first direction, so that the first connecting portion can be separated from the snap-fit ​​pieces; A support component is connected to the end of the base away from the suction cup component, and the support component is used to place the mobile terminal.

[0005] The bracket provided in this application embodiment utilizes a first state and a second state of the base assembly to achieve a detachable connection between the base assembly and the first connecting part, thereby enabling a detachable connection between the base assembly and the suction cup assembly. When the bracket is needed to support the mobile terminal, the base assembly is simply connected to the suction cup assembly; after use, the base assembly and suction cup assembly are detached. This helps reduce the load-bearing weight of the suction cup assembly when the bracket is not needed, thus extending its service life.

[0006] Furthermore, using the bracket of this application, there can be multiple suction cup components, which can be attached to different positions. When it is necessary to change the placement position of the mobile terminal, there is no need to move the suction cup components; only the position of the base component needs to be moved. This helps to reduce the frequency of disassembly and assembly of the suction cup components and helps to extend the service life of the suction cup components.

In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0016] In this embodiment of the application, the first direction is Figure 4 , Figure 11 and Figure 16 The direction indicated by v1 is the second direction. Figure 3 , Figure 4 , Figure 10 , Figure 11 Figure 15 , Figure 16 The direction indicated by v2 is the third direction. Figure 4 , Figure 10 and Figure 15 The directions shown in v3 are roughly perpendicular to each other.

[0017] In this application embodiment, the term "approximately perpendicular" is used to describe the angular relationship between two directions, planes, or components. Its meaning includes, but is not limited to, an absolute, ideal 90-degree perpendicularity. It covers angles close to 90 degrees within engineering design and manufacturing tolerances.

[0018] This application provides a bracket; please refer to [the relevant documentation]. Figure 1 The bracket includes a suction cup assembly 10, a base assembly 20, and a support assembly (not shown in the figure).

[0019] Specifically, the suction cup assembly 10 includes a suction cup 11 and a first connecting portion 12 connected to each other. The suction cup 11 has an adsorption surface for adsorbing onto the adsorption platform. The first connecting portion 12 is located on the side of the suction cup 11 opposite to the adsorption surface.

[0020] For example, such as Figure 12 As shown, the first connecting portion 12 has at least two slots 121a, wherein the two slots 121a are arranged opposite to each other along the first direction.

[0021] "Facing opposite" means that the openings of the card slot 121a face opposite directions.

[0022] Please refer to this simultaneously. Figure 2 , Figure 3 and Figure 4 The base assembly 20 includes a base 21, a return structure 22, a drive structure 23, and at least two snap-fit ​​members 24, wherein the two snap-fit ​​members 24 are disposed opposite each other along a first direction. The base 21 has a receiving space 211a, in which the return structure 22, the drive structure 23, and the snap-fit ​​members 24 are all disposed.

[0023] The support component is connected to the end of the base 21 away from the suction cup component 10, and the support component is used to place the mobile terminal.

[0024] Mobile terminals can be, for example, mobile phones, tablets, etc.

[0025] Understandably, there are no restrictions on how the support components can hold the mobile terminal. For example, they can be equipped with grippers to hold the mobile terminal, or they can be attracted to the mobile terminal using magnets, or they can be implemented using other structures.

[0026] In some embodiments, the base assembly 20 has a first state and a second state; In the first state, the base assembly 20 and the chassis assembly are docked along the second direction, the first connecting part 12 is inserted into the receiving space 211a, and the return structure 22 is used to drive the two snap-fit ​​pieces 24 to move closer to each other along the first direction, so that the two snap-fit ​​pieces 24 are respectively partially snapped into the two slots 121a, and the first direction is approximately perpendicular to the second direction.

[0027] In the first state, the latching member 24 is partially located within the latching slot 121a, which can limit the first connecting member along the second direction. Furthermore, under the action of the return structure 22, the two latching members 24 move closer to each other, clamping the first connecting portion 12 between them, thereby limiting the first connecting portion 12 along the first direction and achieving latching between the first connecting portion 12 and the two latching members 24. In other words, when the base assembly 20 is in the first state, the first connecting portion 12 latches with the two latching members 24, thereby achieving the connection between the suction cup assembly 10 and the base assembly 20.

[0028] In the second state, the drive structure 23 drives the two latching members 24 to move away from each other in the first direction, so that the first connecting portion 12 can be separated from the limiting component. That is, when the base 21 is in the second state, the gap between the two latching members 24 allows the first connecting portion 12 to be separated from the limiting component, thereby facilitating the removal of the base assembly 20 from the suction cup assembly 10.

[0029] The bracket provided in this application embodiment, utilizing the first and second states of the base assembly 20, enables a detachable connection between the base assembly 20 and the first connecting portion 12, thereby enabling a detachable connection between the base assembly 20 and the suction cup assembly 10. When the bracket is needed to support the mobile terminal, the base assembly 20 is simply connected to the suction cup assembly 10; after use, the base assembly 20 is detached from the suction cup assembly 10. Thus, when the bracket is not needed to support the mobile terminal, it helps reduce the load-bearing weight of the suction cup assembly 10 and helps extend its service life.

[0030] Moreover, using the bracket of this application, there can be multiple suction cup components 10, and multiple suction cup components 10 can be attached to different positions. When it is necessary to change the placement position of the mobile terminal, there is no need to move the suction cup components 10, only the position of the base component 20 needs to be moved. This helps to reduce the frequency of disassembly and assembly of the suction cup components 10 and helps to extend the service life of the suction cup components 10.

[0031] It should be noted that when the base assembly 20 is in the first state, an external force along the second direction and away from the suction cup assembly 10 can be applied to the base assembly 20 to drive the first connecting part 12 to move an appropriate distance away from the suction cup assembly 10. The first connecting part 12 drives the suction cup 11 away from the adsorption surface to increase the negative pressure inside the suction cup 11, which helps to enhance the adsorption force.

[0032] It should be noted that the way the first connecting part 12 forms the slot 121a is not limited.

[0033] For example, please refer to Figure 12 The first connecting portion 12 includes a columnar structure 121, a first disc portion 123, and at least two protrusions 124. The protrusions 124 protrude from the outer peripheral surface of the columnar structure 121. The first disc portion 123 is located at the end of the columnar structure 121 away from the adsorption surface. The gap between the first disc portion 123 and the protrusions 124 defines the slot 121a.

[0034] In other embodiments, the first connecting portion 12 includes a columnar structure 121, the outer peripheral surface of which is partially recessed to form a slot 121a.

[0035] For example, the columnar structure 121 is cylindrical, and the end face of the snap-fit ​​member 24 facing the first connecting part 12 in the first state can be an arc surface. The two snap-fit ​​members 24 can enclose a roughly circular structure, which helps to further improve the snap-fit ​​stability between the first connecting part 12 and the snap-fit ​​member 24 in the first state.

[0036] "Approximately circular" means that the end faces of the two snap-fit ​​pieces 24 can contact each other to form a roughly closed circular ring, or they can not contact each other, in which case the circular ring has a notch 2122a.

[0037] In some embodiments, such as Figure 5 As shown, the recovery structure 22 includes at least one elastic element 221, with its two ends connected to two snap-fit ​​elements 24 respectively. In the first state, the elastic element 221 is in a stretched state. Thus, the elastic potential energy stored in the elastic element 221 during the stretching process causes the two snap-fit ​​elements 24 to have a tendency to move closer to each other, thereby ensuring that the snap-fit ​​elements 24 are stably located within the snap-fit ​​groove 121a.

[0038] For example, there are two elastic elements 221, which are arranged opposite each other along a third direction, with the second direction, the first direction, and the third direction being approximately perpendicular to each other. In this way, the elastic elements 221 can provide restoring force to both sides of the snap-fit ​​member 24 along the third direction, which helps to increase the stability of the snap-fit ​​member 24 within the snap-fit ​​groove 121a.

[0039] For example, such as Figure 5 As shown, the base 21 includes a housing 211 and a cover 212. The housing 211 forms a receiving space 211a. The cover 212 is located at the end of the housing 211 away from the adsorption surface along the second direction and is used to cover the receiving space 211a. The cover 212 helps to improve the neatness and aesthetics of the bracket.

[0040] The shape of the shell 211 is not limited. In the orthographic projection on the plane perpendicular to the second direction, the projection of the shell 211 can be circular, square, polygonal, etc.

[0041] In some embodiments, please refer to Figure 3 , Figure 4 , Figure 15 and Figure 16 The base assembly 20 includes a support base 26, which is at least partially located within the receiving space 211a. A snap-fit ​​member 24 is supported on the support base 26. The support base 26 is directly or indirectly connected to the base 21. The support base 26 has a first opening 2121, which allows at least the first connecting portion 12 to be inserted. Thus, the support base 26 provides support for the snap-fit ​​member 24, helping to improve the stability of the snap-fit ​​members 24 during their movement away from or towards each other.

[0042] In some embodiments, such as Figure 4 As shown, the snap-fit ​​member 24 is formed with a first inclined surface 241, which is inclined along the second direction and from the base 21 toward the adsorption surface, toward the direction of approaching another snap-fit ​​member 24. When the first connecting part 12 and the base 21 approach each other along the second direction, the first connecting part 12 pushes the first inclined surface 241 away from the adsorption surface, so that the two snap-fit ​​pieces 24 move away from each other along the first direction.

[0043] In this embodiment, taking the suction cup assembly 10 adsorbing onto the adsorption platform as an example, the base assembly 20 is moved toward the direction of the first connecting part 12. The end of the columnar structure 121 of the first connecting part 12 away from the adsorption surface contacts the first inclined surface 241, thereby pushing the first inclined surface 241 away from the adsorption surface, thereby causing the two snap-fit ​​pieces 24 to move away from each other. In this way, the first connecting part 12 can be inserted into the receiving space 211a. When the first connecting part 12 separates from the first inclined surface 241, the two snap-fit ​​pieces 24 approach each other under the action of the restoring force of the restoring structure 22, and then snap into the corresponding slot 121a.

[0044] It is understood that in other embodiments, when the suction cup assembly 10 and the base assembly 20 are in a separated state, the driving structure 23 can also drive the snap-fit ​​member 24 to move in the first direction away from the first connecting part 12. After the columnar structure 121 of the first connecting part 12 enters the receiving space 211a, the driving structure 23 is released, so that the snap-fit ​​member 24 is snapped into the slot 121a under the restoring force of the restoring structure 22.

[0045] In some embodiments, a second inclined surface 122 is formed at the end of the first connecting portion 12 away from the adsorption surface. The second inclined surface 122 is used to press and push the first inclined surface 241 as the first connecting portion 12 and the base 21 approach each other in the second direction. Thus, when the base assembly 20 is installed, the second inclined surface 122 first contacts the first inclined surface 241 and then pushes the first inclined surface 241, which helps to increase the contact area between the first connecting portion 12 and the snap-fit ​​member 24 and helps to improve the stability of the first connecting portion 12 relative to the base 21 in the second direction.

[0046] In some embodiments, the hardness of the first connecting portion 12 is greater than that of the suction cup 11. Thus, the harder hardness of the first connecting portion 12 facilitates the provision of sufficient mechanical strength for cooperation with the base 21, while the lower hardness of the suction cup 11 facilitates its elastic deformation to adhere to the surface and expel air to form a vacuum.

[0047] The material of the first connecting part 12 is not limited; for example, it can be a plastic part.

[0048] The material of suction cup 11 is not limited; for example, it can be a polyurethane elastic component.

[0049] It is understandable that the structure of the drive structure 23 is not limited, as long as it enables the snap-fit ​​member 24 to move in the first direction away from the first connecting part 12.

[0050] In some embodiments, such as Figure 3 and Figure 4 As shown, the driving structure 23 includes a first driving member 231, which is located on the side of the latching member 24 away from the adsorption surface. The first driving member 231 can move back and forth along the second direction. During the movement of the first driving member 231 along the second direction and close to the latching member 24, it can drive the two latching members 24 to move away from each other along the first direction. In this way, the latching members 24 are disengaged from the slot 121a.

[0051] When the first driving component 231 drives the card connector 24 to move, the base assembly 20 can be moved from the first state (e.g., Figure 4 (As shown) Switch to the second state (as shown) Figure 11 (As shown).

[0052] The manner in which the first driving member 231 moves toward the snap-fit ​​member 24 in the second direction is not limited. For example, it can be by applying a thrust or pressure along the second direction toward the adsorption surface to the first driving member 231. In this embodiment, a through hole 212a is formed on the cover 212 so that the user can apply force to the first driving member 234.

[0053] In the first state, the first driving member 234 is disposed in the through hole 212a, and the end face of the first driving member 234 away from the adsorption surface is flush with the end face of the cover 212 away from the adsorption surface. This helps to improve the neatness and aesthetics of the bracket.

[0054] For example, the snap-fit ​​member 24 has an insertion channel 242, and the inner wall of the insertion channel 242 has a third inclined surface 243. The first driving member 231 is located on the side of the insertion channel 242 away from the adsorption surface. During the movement of the first driving member 231 toward the snap-fit ​​member in the second direction, part of the structure enters the insertion channel 242 and is used to push the third inclined surface 243 to move in the first direction away from the first connecting part 12.

[0055] In this embodiment, when the first driving member 231 moves toward the snap-fit ​​member 24, the first driving member 231 cooperates with the third inclined surface 243 to drive the snap-fit ​​member 24 to move along the first direction toward the direction away from the first connecting part 12, so that the two snap-fit ​​members 24 move away from each other and the snap-fit ​​member 24 exits the slot 121a.

[0056] For example, such as Figure 6 As shown, the first driving member 231 includes a second disc portion 2311 and an insertion portion 2312. The insertion portion 2312 is used to push the third inclined surface 243 to move in a first direction away from the first connecting portion 12. That is, the second disc portion 2311 drives the insertion portion 2312 into the insertion channel 242 to cooperate with the third inclined surface 243.

[0057] In some embodiments, a fourth inclined surface 2312a is provided at one end of the insertion part 2312 facing the third inclined surface 243. During the movement of the insertion part 2312 toward the snap-fit ​​member 24 in the second direction, the fourth inclined surface 2312a cooperates with the third inclined surface 243 and is used to push the third inclined surface 243 to move in the first direction away from the first connecting part 12.

[0058] In some embodiments, such as Figure 3 and Figure 7 As shown, the base assembly 20 includes a pressure plate 25, which is disposed between the second disc portion 2311 and the snap-fit ​​member 24. The pressure plate 25 has a first through hole, through which at least the insertion portion 2312 passes. The pressure plate 25 is directly or indirectly connected to the base 21. The driving structure 23 includes a first elastic return member 233, which is disposed between the pressure plate 25 and the second disc portion 2311, and is used to drive the second disc portion 2311 to reset. In this embodiment, during the movement of the second disc portion 2311 driving the insertion portion 2312 closer to the snap-fit ​​member 24, the first elastic return member 233 is compressed. At this time, the first elastic return member 233 stores elastic potential energy. When the force applied to the second disc portion 2311 is released, the first elastic return member 233 drives the second disc portion 2311 to reset based on the previously stored elastic potential energy.

[0059] For example, the pressure plate 25 can be connected to the support base 26.

[0060] For example, the pressure plate 25 is provided with a second through hole, and the first driving member 231 includes a connecting post 2313 and a limiting member 2314. The connecting post 2313 is connected to the side of the second disc portion 2311 facing the adsorption surface. The connecting post 2313 passes through the second through hole and can slide back and forth in the second direction within the second through hole. The limiting member 2314 is connected to the end of the connecting post 2313 and is provided on the side of the second through hole facing the adsorption surface. The limiting member 2314 can abut against the side of the pressure plate 25 facing the adsorption surface.

[0061] In this embodiment, the second through hole is used to limit the movement of the connecting post 2313 in a plane perpendicular to the first aspect, while facilitating the sliding of the connecting post 2313 back and forth along the second direction. The two ends of the connecting post 2313 are respectively connected to a limiting member 2314 and a second disc portion 2311. The limiting member 2314 and the second disc portion 2311 form a limiting effect on the connecting post 2313, preventing it from disengaging from the second through hole, thereby improving the stability of the first driving member 231's back-and-forth movement along the second direction.

[0062] For example, the first elastic return member 233 is sleeved on the outer periphery of the connecting post 2313. In this way, the connecting post 2313 plays a guiding and positioning role, which can effectively prevent the first elastic return member 233 from shifting, and help improve the stability of the first driving member 231 during movement.

[0063] It is understood that in this embodiment, the two ends of the first elastic recovery member 233 can be connected to the second disc portion 2311 and the pressure plate 25 respectively, or they can be separated from the second disc portion 2311 and the pressure plate 25 respectively. Alternatively, one end of the first elastic recovery member 233 can be connected to the pressure plate 25 and the other end can be separated from the second disc portion 2311, or one end of the first elastic recovery member 233 can be connected to the second disc portion 2311 and the other end can be separated from the pressure plate 25.

[0064] For example, the first elastic restoring element 233 can be a tension spring, a compression spring, etc.

[0065] In other embodiments, the first elastic recovery member 233 and the connecting post 2313 can also be provided separately, that is, the first elastic recovery member 233 and the connecting post 2313 are spaced apart. In this embodiment, the two ends of the first elastic recovery member 233 can be connected to the second disc portion 2311 and the pressure plate 25 respectively.

[0066] In some other embodiments, please refer to Figure 15 , Figure 16 and Figure 17 The driving structure 23 includes a second driving member 234, which is disposed on the outer periphery of the first connecting portion 12 and is rotatable relative to the first connecting portion 12. The second driving member 234 is used to drive the two latching members 24 away from each other during rotation in the first rotation direction. In this embodiment, the rotation of the second driving member 234 relative to the first connecting portion 12 drives the two latching members 24 away from each other, facilitating the exit of the latching members 24 from the slot 121a.

[0067] It is understandable that the first rotation direction can be either counterclockwise or clockwise.

[0068] For example, such as Figure 17 As shown, the first rotation direction is the direction indicated by v4 in the figure, which is the counterclockwise direction on the paper.

[0069] For example, such as Figure 17 As shown, the second driving member 234 has a groove 2341 that extends along the first rotation direction. The snap-fit ​​member 24 has a protrusion 244 that slides within the groove 2341. The groove 2341 has a first end 2341a and a second end 2341b. The first end 2341a is located on the side of the second end 2341b facing the first rotation direction. The radial distance between the first end 2341a and the first connecting portion 12 is less than the radial distance between the second end 2341b and the first connecting portion 12. In the first state, the protrusion 244 is located at the first end 2341a of the groove 2341; In the second state, the second drive member 234 rotates in the first rotation direction such that the protrusion 244 is located at the second end 2341b of the groove 2341.

[0070] In this embodiment, as the second driving member 234 rotates relative to the first connecting portion 12, the slide groove 2341 also rotates with the second driving member 234. At this time, the protrusion 244 moves relative to the slide groove 2341 in a second rotation direction, which is opposite to the first rotation direction. When the protrusion 244 moves to the second end 2341b of the slide groove 2341, the protrusion 244 drives the snap-fit ​​member 24 to move in a first direction away from the first connecting portion 12, so that the snap-fit ​​member 24 can exit the slot 121a and separate from the first connecting portion 12.

[0071] It is understood that the position of the protrusion 244 on the snap-fit ​​member 24 is not limited. Exemplarily, the protrusion 244 is formed at the end of the snap-fit ​​member 24 away from the first connecting portion 12.

[0072] In some embodiments, the housing 211 is rotatable relative to the support 26, and the housing 211 is connected to the second driving member 234. Thus, when the base assembly 20 needs to be disassembled, only the housing 211 needs to be rotated along the first rotation direction. The housing 211 will drive the second driving member 234 to rotate, thereby moving the latching member 24 away from the first connecting portion 12, facilitating the separation of the base assembly 20 from the suction cup assembly 10. In some embodiments, the driving structure 23 includes a second elastic return member 235. During the rotation of the second driving member 234 along the first rotation direction, the second driving member 234 compresses or stretches the second elastic return member 235, which drives the second driving member 234 to move in the second rotation direction. That is, when the first connecting portion 12 separates from the latching member 24, the force applied to the housing 211 stops. At this time, the second elastic return member 235, based on its stored elastic potential energy, drives the second driving member 234 to reset, and the second driving member 234 drives the housing 211 to reset.

[0073] For example, the second elastic return element 235 may be a pawl spring.

[0074] For example, such as Figure 18 and Figure 19 As shown, the support base 26 has a protruding structure 2122 on its surface facing the snap-fit ​​member 24. The snap-fit ​​member 24 is disposed in the protruding structure 2122. The protruding structure 2122 has at least two notches 2122a in the circumferential direction. The notches 2122a allow the end of the snap-fit ​​member 24 away from the first connecting part 12 to be inserted in the second direction. Thus, the notches 2122a limit the snap-fit ​​member 24 in the circumferential direction, so that the snap-fit ​​member 24 will not rotate in the circumferential direction when the second driving member 234 rotates relative to the first connecting part 12.
