Description

Technical Field

[0001] This utility model relates to the field of mobile phone accessories technology, and more specifically, to a connection structure and a mobile phone stand. Background Technology

[0002] With the development of mobile internet technology and the widespread use of smart terminals, mobile phones have become an indispensable tool for people's daily travel, especially while driving, where they are often used for navigation, making and receiving calls, and other scenarios. To ensure driving safety and ease of use, car phone holders have emerged, which can stably fix the phone in a suitable position inside the car, making it convenient for the driver to view and operate.

[0003] Among various car phone holders, flexible holders with adjustable rods are widely used due to their flexibility and adaptability. These flexible holders typically include a flexible support arm that can be bent and shaped arbitrarily, and a fixed base and a support base respectively located at both ends of the flexible support arm. The fixed base is used to connect and fix to the vehicle (such as in the air vents, dashboard, windshield, etc.), while the support base is used to support and fix the phone, with the side in contact with the phone forming a support surface. By bending the flexible support arm, the spatial position of the support base and the phone can be adjusted to adapt to the interior layout of different car models and the usage habits of different drivers.

[0004] However, in existing flexible brackets, the support base and flexible support arm are mostly fixedly connected, and the support surface of the support base faces a fixed position relative to the flexible support arm (i.e., the support surface either faces "above" or "below" the flexible support arm). This fixed orientation causes the orientation of the support surface to change uncontrollably with the bending angle of the flexible support arm: for example, when the flexible support arm bends downward, the support surface may face the driver, but when it bends upward, the support surface will face away from the driver; or conversely, when the flexible support arm bends upward, the support surface faces the user, and when it bends downward, it faces away from the user. Due to differences in installation positions (such as air vent height, dashboard tilt angle) in different vehicle models, and different drivers having different viewing angle requirements for their mobile phones, the bending angle of the flexible support arm needs to be frequently adjusted. The passive change in the orientation of the support surface with the bending angle means that the mobile phone screen cannot always maintain the optimal state facing the driver, seriously affecting ease of use, and may even pose a safety hazard because the driver has to look down or turn to the side to view the screen.

[0005] To address these issues, an improved flexible bracket has emerged on the market. This improved bracket incorporates a pivot structure between the support base and the flexible support arm. By rotating the support base relative to the flexible support arm, the orientation of the support surface can be independently adjusted, thus counteracting the impact of changes in the bending angle of the flexible support arm on the orientation of the support surface. However, this solution has significant drawbacks: Firstly, the addition of the pivot structure inevitably increases the thickness or length of the connection between the support base and the flexible support arm, leading to an increase in the overall product size, compromising the bracket's compactness and aesthetics, and potentially causing interference with other components inside the vehicle. Secondly, as a movable connector, the pivot is prone to breakage and damping failure (i.e., inability to maintain the positioning angle) after frequent rotation and adjustment or prolonged stress (such as the weight of a mobile phone or the impact of vehicle bumps), severely affecting the product's lifespan and reliability.

[0039] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0040] like Figures 1 to 3 As shown, this utility model discloses a connection structure 1 applied to a mobile phone holder. The mobile phone holder includes a support arm 2 and a mounting base 3. The mounting base 3 is used to directly or indirectly mount mobile devices. The connection structure 1 includes a rotating component 11 and a damping component 12. The rotating component 11 includes a first rotating component 111 and a second rotating component 112. The second rotating component 112 is provided with a connecting part 1122, which is connected to the first rotating component 112. The first rotating component 111 and the connecting part 1122 can rotate relative to each other.

[0041] The connecting portion 1122 extends to form extension portions 1121 on both sides of the first rotating member 111. Specifically, the extension portion 1121 can be an independent component connected to the connecting portion 1122 by fasteners such as screws, or it can be integrally formed with the connecting portion 1122, and there is no specific limitation here.

[0042] Specifically, regarding the specific implementation of the rotating member 11, in one embodiment, as follows: Figure 1 and Figure 2As shown, the connecting portion 1122 of the second rotating member 112 is sleeved on the sleeve post 1112, and the two sides of the connecting portion 1122 are integrally formed into extension portions 1121. In another embodiment, the connecting portion 1122 and the first rotating member 111 are connected by a damping connection method similar to a one-line damping shaft, so that the first rotating member 111 and the second rotating member 112 achieve a damped rotational connection, and the extension portions 1121 can be integrally formed on both sides of the connecting portion 1122 (e.g., Figure 14 As shown, it can be tightly fitted onto the connecting part 1122 with an interference fit. The damping member 12 is mounted on the first rotating member 111 and is used to provide damping for rotation between the first rotating member 111 and the second rotating member 112.

[0043] Of the first rotating member 111 and the extension 1121, one is used for fixed connection with the support arm 2, and the other is used for fixed connection with the mounting base 3. Specifically, in optional embodiments, the first rotating member 111 can be fixedly connected to the support arm 2 and the extension 1121 can be connected to the mounting base 3; or the extension 1121 can be fixedly connected to the support arm 2 and the first rotating member 111 can be connected to the mounting base 3.

[0044] The first rotating component 111, the second rotating component 112, and the damping component 12 are all rigid components. The first rotating component 111 and the damping component 12 are metal components; the second rotating component 112 or the connecting part 1122 is either a metal component or a plastic component. Specifically, the metal component can be a part made of pure metal, or a part that is mostly metal with the remainder made of other materials. The plastic component can be a part made of pure plastic, or a part that is mostly plastic with the remainder made of other materials.

[0045] The connecting structure 1 of this utility model is used to connect the support arm 2 and the mounting base 3 of a mobile phone holder. The connecting structure 1 consists of a rotating component 11 and a damping component 12. The rotating component 11 includes a first rotating component 111 and a second rotating component 112. The first rotating component 111 is provided with the damping component 12. In application, one of the first rotating component 111 and the extension 1121 is fixedly connected to the support arm 2, and the other is fixedly connected to the mounting base 3. Through the damping provided by the damping component 12, the first rotating component 111 and the second rotating component 112 can rotate relative to each other, and the damping effect keeps the mounting base 3 at the desired rotation angle. The force on the connecting structure 1 is distributed through the first rotating component 111 and the second rotating component 112, especially through the extensions 1121 located on both sides of the first rotating component 111, making the rotating component 11 less prone to breakage or damping failure, thus improving the service life and reliability of the connecting structure 1.

[0046] Specifically, the first rotating member 111 and the second rotating member 112 can rotate 360°.

[0047] Specifically, in one embodiment, the extensions 1121 on both sides of the first rotating member 111 are used for mounting in the mounting groove 21 at the end of the support arm 2. The extensions 1121 improve the mounting strength of the second rotating member 112 by being mounted in the mounting groove 21 at the end of the support arm 2.

[0048] At least one first through hole 11211 is provided on each of the extensions 1121 on both sides of the first rotating member 111. Specifically, two or more first through holes 11211 can be provided on each side of the extension 1121 of the first rotating member 111, and the first through holes 11211 are evenly spaced apart. The first through holes 11211 are used to fixably connect to the first connecting holes 22 in the mounting groove 21 through the first fastener 4. When two or more first through holes 11211 are provided on each side of the extension 1121 of the first rotating member 111, the number and position of the first connecting holes 22 are also set accordingly. Specifically, the first fastener 4 is a screw, and the first connecting hole 22 is a screw hole.

[0049] The first rotating member 111 has a second connecting hole 1111 at its end away from the support arm 2. The second connecting hole 1111 is used to fix it to the second through hole 31 of the mounting base 3 through the second fastener 5. Specifically, the second connecting hole 1111 is a screw hole, and the second fastener 5 is a screw.

[0050] Specifically, the axis of the first connecting hole 22 and the axis of the second connecting hole 1111 are parallel to the axis of rotation of the rotating member 11.

[0051] Furthermore, the damping element 12 includes a damping ring 121 and at least two damping pads 122. The damping ring 121 is axially adjustable and mounted on one end of the first rotating member 111. The damping ring 121 is sleeved on the first rotating member 111 and distributed on both sides of the second rotating member 112. The damping ring 121 presses against the damping pads 122 and the second rotating member 112 to generate damping. By pressing the damping pads 122 and the second rotating member 112 with the damping ring 121, damping is generated on both sides of the second rotating member 112 and the damping rings 121, thereby enabling the mounting base 3 and the support arm 2 to be positioned after rotation. There are at least two damping pads 122, with at least one damping pad 122 on each side of the second rotating member 112. On the first rotating member 111, a damping ring 121 is located on one side of the second rotating member 112. There is at least one damping pad 122 between the damping ring 121 and the second rotating member 112. Of course, there can also be two or more damping pads 122 between the damping ring 121 and the second rotating member 112. At least one damping pad 122 is also sleeved on the other side of the second rotating member 112. The damping pad 122 can be limited by setting a protruding ring edge on the circumferential surface of the first rotating member 111 to prevent the damping ring 121 from pressing tightly. The damping pad 122 and the second rotating member 112 can move in the axial direction of the first rotating member 111.

[0052] Preferably, one end of the first rotating member 111 is provided with a sleeve post 1112, and the circumferential surface of the sleeve post 1112 is provided with threads. The damping ring 121 is a nut, which is screwed onto the threads. The diameter of the sleeve post 1112 is smaller than the diameter of the rest of the first rotating member 111. The damping pad 122 and the second rotating member 112 are sleeved on the sleeve post 1112, and the nut presses the damping pad 122 and the second rotating member 112 together. By rotating the nut to press the damping pad 122 and the second rotating member 112 together, the damped rotation of the first rotating member 111 and the second rotating member 112 is achieved.

[0053] The circumferential surface of the first rotating member 111 is provided with a limiting plane 1113 along the axial direction. When the first rotating member 111 is inserted into the second through hole 31 in the mounting base 3, the limiting plane 1113 limits the rotation between the first rotating member 111 and the mounting base 3.

[0054] like Figures 4 to 13 As shown, this utility model also discloses a mobile phone holder, including a mounting base 3, a support arm 2, and the aforementioned connecting structure 1; of the first rotating member 111 and the extension 1121, one is used for fixed connection with the support arm and the other is used for fixed connection with the mounting base 3. In optional embodiments, during application, the first rotating member 111 can be fixedly connected to the support arm 2, and the extension 1121 can be connected to the mounting base 3; alternatively, the extension 1121 can be fixedly connected to the support arm 2, and the first rotating member 111 can be connected to the mounting base 3.

[0055] The extensions 1121 on both sides of the first rotating member 111 are installed in the mounting grooves 21 at the ends of the support arm 2. The extensions 1121 improve the mounting strength of the second rotating member 112 by being installed in the mounting grooves 21 at the ends of the support arm 2. A cover plate 6 can be further provided on the mounting groove 21 to cover the mounting groove 21 and the extensions 1121.

[0056] At least one first through hole 11211 is provided on each of the extensions 1121 on both sides of the first rotating member 111. The first through hole 11211 is fixedly connected to the first connecting hole 22 in the mounting groove 21 by a first fastener 4. Two or more first through holes 11211 can be provided on each side of the extension 1121 of the first rotating member 111, and the first through holes 11211 are evenly spaced. When two or more first through holes 11211 are provided on each side of the extension 1121 of the first rotating member 111, the number and position of the first connecting holes 22 are also set accordingly. Specifically, the first fastener 4 is a screw, and the first connecting hole 22 is a screw hole.

[0057] The first rotating member 111 has a second connecting hole 1111 at the end away from the support arm 2. The second connecting hole 1111 is fixedly connected to the second through hole 31 of the mounting base 3 through a second fastener 5. Specifically, the second connecting hole 1111 is a screw hole, and the second fastener 5 is a screw.

[0058] Furthermore, the mounting base 3 has a hollow interior forming an inner cavity 32, which communicates with the second through hole 31. The second fastener 5 is connected from one side of the inner cavity 32 to the second connecting hole 1111 and the second through hole 31. The inner cavity 32 has an opening at the end of the mounting base 3 away from the support arm 2. The mounting base 3 also includes a sealing member 33, which seals the opening. When assembling the connecting structure 1, the extension 1121 is first installed in the mounting groove 21 at the end of the support arm 2 using screws (first fastener 4). Then, the first rotating member 111 is inserted into the second through hole 31. The operator screws (second fastener 5) into the second connecting hole 1111 from the opening, and then seals the opening with the sealing member 33. The sealing member 33 can be fixed to the opening with glue.

[0059] Specifically, the sealing member 33 includes two opposing filling arms 331, which are inserted into the inner cavity 32 to fill it. A clearance area is formed between the two opposing filling arms 331, clearing the solid area of ​​the second through hole 31 within the mounting base 3. The inner cavity 32 provides ample operating space, making it easier to screw the second fastener 5 into the second connecting hole 1111. The filling arms 331 can fill the inner cavity 32, improving the structural strength of the mounting base 3.

[0060] The mounting base 3 is also provided with a mounting part 34, such as a ball head. The mounting part 34 can be directly connected to the phone case to fix the phone, or it can be connected to a clamping mechanism, magnetic mechanism, etc. to fix the phone. The support arm 2 is connected to the fixing base 7 of the phone holder, and the fixing base 7 can be attached to the fixing surface by suction cup 8 at its bottom.
