Description

Technical Field

[0001] This utility model relates to the field of mobile phone holder technology, and in particular to a vehicle-mounted mobile phone holder. Background Technology

[0002] Car phone holders, as a common car accessory, primarily provide drivers with a safe and stable position to hold their phones, facilitating navigation, answering calls, playing music, and other operations while driving. With the widespread adoption of smartphones and the rapid development of the automotive industry, car phone holders are no longer just simple accessories, but rather intelligent hardware products integrating more functions and innovative designs, becoming an indispensable tool for car owners in their daily driving.

[0003] Traditional car phone holders typically rely on simple mechanical structures to clamp and support the phone in a suitable position inside the car. While these holders meet basic needs, they have limitations in terms of stability, adjustability, and ease of use. With technological advancements and the diversification of user needs, more and more manufacturers are exploring more innovative design solutions to promote a comprehensive improvement in the functionality of car phone holders. Currently, manufacturers mainly use suction to fix car phone holders on a flat surface by generating vacuum suction force, which provides strong stability. However, when designing car phone holders, the following aspects should be considered: (1) The ability to use new holders for locking and suction, i.e., to quickly and securely attach the car phone holder to the car body contact surface; (2) Ensuring that the phone can be adjusted in multiple directions for easy use; (3) Ensuring stability during adjustment. (4) It is also necessary to consider not only meeting basic stability and safety requirements but also having good adjustability and ease of use. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a car phone holder, including a connecting arm and a magnetic suction part and a fixing part disposed at opposite ends of the connecting arm. The magnetic suction part is embedded with a first magnet, which is used to magnetically fix the phone. The fixing part is rotatably connected to the connecting arm. The fixing part includes a soft rubber suction cup disposed at the bottom of the fixing part, a threaded post, and a knob disposed on the fixing part. The soft rubber suction cup is fixed on the threaded post, which is located at the center of the soft rubber suction cup. The threaded post is threadedly connected to the knob. When the knob is rotated clockwise or counterclockwise, the threaded post slides downward and causes the soft rubber suction cup to deform, resulting in negative pressure between the soft rubber suction cup and the surface it is in contact with.

[0006] Furthermore, the bottom of the soft rubber suction cup is concave, and an assembly layer is provided in the middle of the soft rubber suction cup. The lower end of the threaded column is provided with an assembly part filled in the assembly layer. The assembly part is installed in the assembly layer and the threaded column causes the assembly layer on the soft rubber suction cup to be pulled up and pressed down.

[0007] Furthermore, the concave part of the soft rubber suction cup is filled with an adhesive layer for adhering the contact surface, and a handle is provided on the outer side of the soft rubber suction cup.

[0008] Furthermore, the fixing part also includes a bottom shell fixed to the upper end of the soft rubber suction cup and located between the threaded post and the knob; a toothed fixing part is provided between the lower end of the bottom shell and the upper end of the soft rubber suction cup; a through hole for the threaded post to pass through is provided at the center of the bottom shell; a limiting post is provided at intervals on the upper end of the bottom shell, and multiple limiting posts are arranged in a ring, and an arc-shaped groove is provided on the knob for the corresponding limiting post to pass through.

[0009] Furthermore, a first damping component is provided at the upper end of the bottom shell near the edge. The first damping component includes a lower compartment, a lower spring component is provided on the inner wall of the lower compartment, a lower damping block with a tapered end is provided on the outer side of the lower spring component, and a lower tooth is provided on the inner side of the knob to contact the lower damping block.

[0010] Furthermore, the toothed fixing part consists of a lower toothed joint spaced at the lower end of the bottom shell and an upper toothed joint spaced at the upper end of the soft rubber suction cup; the teethed joints between the lower and upper teethed joints are interlocked with the gaps between them.

[0011] Furthermore, it also includes an upper base assembled on the bottom shell, with the middle of the threaded column being hollow, and a vertically placed intermediate elastic element installed inside the hollow, the intermediate elastic element abutting against the upper base at the top.

[0012] Furthermore, a partition is assembled between the upper base and the bottom shell, and the connecting arm includes a connector sleeved on the outer layer of the partition and rotating around the outer ring of the partition, and the partition is fixed to the bottom shell by bolts.

[0013] Furthermore, a second damping component is provided at the upper end of the partition near the edge. The second damping component includes an upper compartment, an upper spring component is provided on the inner wall of the upper compartment, an upper damping block with a tapered end is provided on the outer side of the upper spring component, and an upper tooth is provided on the inner side of the connector to contact the upper damping block.

[0014] Furthermore, the connecting arm includes an inner metal sheet and a soft rubber layer covering the outside of the metal sheet.

[0015] Furthermore, the connector is also fitted with a zinc alloy part to enhance the strength of the connection point between the connecting arm and the fixing part.

[0016] The beneficial effects of this utility model are:

[0017] (1) The vehicle mobile phone holder uses a connecting arm to connect the magnetic part for magnetically attaching the mobile phone and the main component for fixing it to the vehicle, thereby realizing its overall modularity.

[0018] (2) The car phone holder has a simple fixing method. After placing its soft rubber suction cup on the contact surface of the car, you only need to rotate the knob to make the threaded column move downwards or downwards. When moving downwards, it will simultaneously drive the assembly layer on the soft rubber suction cup to move downwards, thereby expelling the gap in the concave shape to form a negative pressure, thereby achieving the adsorption effect.

[0019] (3) The car phone holder can be adjusted in multiple directions by means of the rotating connection between the connecting arm and the fixing part, so that its axial orientation can be rotated and adjusted. On the other hand, it can be bent by means of the connecting arm composed of the internal metal sheet and the soft rubber layer covering the outside of the metal sheet. Finally, the phone holder can be adjusted in multiple directions.

[0020] (4) When the car phone holder rotates the knob and connecting arm, it is subject to the corresponding damping component, which can make the rotation process damped to prevent random rotation.

[0021] (5) The car phone holder has a soft suction cup filled with an adhesive layer for adhering the contact surface to increase stability during fixation. Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0033] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] Please see Figures 1-7 This utility model includes a connecting arm 1 and magnetic suction parts 2 and fixing parts 3 disposed at opposite ends of the connecting arm 1. The magnetic suction parts 2 are embedded with a first magnet 21, which is used to magnetically fix the mobile phone. The fixing parts 3 are rotatably connected to the connecting arm 1. The fixing parts 3 include a soft rubber suction cup 31 disposed at the bottom of the fixing parts 3, a threaded post 32, and a knob 33 disposed on the fixing parts 3. The soft rubber suction cup 31 is fixed on the threaded post 32, which is located at the center of the soft rubber suction cup 31. The threaded post 32 is threadedly connected to the knob 33. When the knob 33 is rotated clockwise or counterclockwise, the threaded post 32 slides downward to form a squeezing state on the soft rubber suction cup 31, so that the bottom surface of the soft rubber suction cup 31 is in contact with the plane and forms a sealed space. A negative pressure effect is generated inside the two and they are fixed to each other.

[0035] This technical solution mainly uses the magnetic suction part 2 for magnetic mobile phones, the fixing part 3 that forms a fixed adsorption with the negative pressure of the contact surface, and the connecting arm 1 in the middle to assemble and design a car mobile phone holder with modularity, fast adsorption and fixation, and multi-faceted angle adjustment.

[0036] Example 1: Reference Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, the main structural components that achieve the magnetic fixation principle are:

[0037] The bottom of the soft rubber suction cup 31 is concave, and an assembly layer 311 is provided in the middle of the soft rubber suction cup 31. The lower end of the threaded post 32 is provided with an assembly part 321 filled in the assembly layer 311. The assembly part 321 is installed in the assembly layer 311 and the threaded post 32 causes the assembly layer 311 on the soft rubber suction cup 31 to be pulled up and pressed down by linkage. The fixing part 3 also includes a bottom shell 34 fixed to the upper end of the soft rubber suction cup 31 and provided outside the threaded post 32 and between the knob 33. The lower end of the bottom shell 34 and the upper end of the soft rubber suction cup 31 are provided with a bottom shell 34. The toothed fixing part 3 is assembled with a lower toothed tooth 343 spaced at the lower end of the bottom shell 34 and an upper toothed tooth 314 spaced at the upper end of the soft rubber suction cup 31. The teeth and gaps between the lower toothed tooth 343 and the upper toothed tooth 314 are staggered and spliced. The bottom shell 34 has a through hole 341 for the threaded post 32 to pass through at the center. The upper end of the bottom shell 34 has a limiting post 342 spaced at a time. Multiple limiting posts 342 are arranged in a ring. The knob 33 has an arc groove 331 for the corresponding limiting post 342 to pass through.

[0038] The above structure specifically includes four parts: a soft rubber suction cup 31, a threaded post 32, a bottom shell 34, and a knob 33;

[0039] The lower end of the soft rubber suction cup 31 is concave, and an assembly layer 311 that can be pressed down and lifted is provided in the middle. The purpose is to expel the air in the concave shape by applying force to the assembly layer 311 when the soft rubber suction cup 31 is placed on the contact surface of the vehicle body, thereby ultimately forming negative pressure adsorption. The force is applied by the user rotating the knob 33, which is completed by rotating the knob 33 clockwise and counterclockwise, and then through the middle assembly structure. The specific assembly method of the assembly structure is as follows: 1. The assembly of the soft rubber suction cup 31 and the threaded post 32 is as follows: the assembly part 321 at the lower end of the threaded post 32 fills the assembly layer 311 at the upper end of the soft rubber suction cup 31, thereby assembling the threaded post 32 at the center of the upper end of the soft rubber suction cup 31. 2. The assembly of the bottom shell 34 sleeved on the upper end of the soft rubber suction cup 31 and the outer periphery of the threaded post 32 is as follows: A ring-shaped lower toothed joint 343 is provided at the lower end of the bottom shell 34, and an upper toothed joint 314 is provided at the upper end of the soft rubber suction cup 31. The teeth and gaps between the lower toothed joint 343 and the upper toothed joint 314 are interlocked to form an assembly. 3. The assembly of the knob 33 with the threaded post 32 and the bottom shell 34, and the assembly of the knob 33 being fitted around the bottom shell 34, is as follows: the upper end of the knob 33 is provided with a panel, and the middle of the panel is provided with an internal threaded part, which realizes the threaded connection with the threaded post 32 through the internal threaded part. At the same time, the panel is provided with several arc-shaped grooves 331, and the bottom shell 34 is provided with an upward limiting post 342. That is, through the cooperation of the internal threaded part with the threaded post 32, and the arc-shaped grooves 331 with the limiting post 342, the assembly of the threaded post 32, the bottom shell 34 and the knob 33 is finally realized.

[0040] The above describes the overall assembly method for achieving pressure adsorption. After assembly, the overall adsorption principle is as follows: the limiting post 342 and the arc groove 331 limit the rotation angle of the knob 33. When the knob 33 rotates clockwise or counterclockwise, it will drive the threaded post 32 of the threaded connection to move up or down. When the threaded post 32 moves down, it will simultaneously drive the assembly layer 311 on the soft rubber suction cup 31 to move down, thereby expelling the air in the concave shape under the soft rubber suction cup 31 and thus achieving negative pressure.

[0041] Meanwhile, the soft rubber suction cup 31 is filled with a self-adhesive layer 312 for adhering to the contact surface. The self-adhesive layer 312 is located on the periphery of the assembly layer 311, and its function is to increase the stability during fixation. A handle 313 is provided on the outer ring of the soft rubber suction cup 31 to facilitate lifting the soft rubber suction cup 31.

[0042] Example 2: Reference Figure 7 As shown, the principle behind the damping effect when knob 33 is rotated is as follows:

[0043] A first damping component 35 is provided near the edge of the upper end of the bottom shell 34. The first damping component 35 includes a lower compartment 351, and a lower spring 352 is provided on the inner wall of the lower compartment 351. The lower spring 352 has a lower damping block 353 with a tapered end along its outer edge. The inner side of the knob 33 is provided with lower teeth 332 that contact the lower damping block 353. Based on the above embodiment, when the knob 33 is rotated, the lower teeth 332 will press the lower spring 352 at the rear end of the lower damping block 353, and the final damping effect of the knob 33 is obtained through the elastic action of the lower spring 352.

[0044] It also includes an upper base 36 assembled on the bottom shell 34. The middle part of the threaded column 32 is hollow 322. A vertically placed intermediate elastic element 323 is installed in the hollow 322. The intermediate elastic element 323 elastically abuts against the upper base 36 at the upper end. That is, when the threaded column 32 moves down, due to the elastic force of the intermediate elastic element 323 itself, there is a damping force that resists the rotation of the knob 33 when the knob 33 is rotated, which can ultimately improve the further damping effect of the knob 33.

[0045] Example 3: Reference Figure 2 , Figure 4 , Figure 7 As shown, the assembly method for the connecting arm 1 that rotates relative to the fixed part 3 and the damping effect during the rotation of the connecting arm 1 is as follows:

[0046] Based on Embodiment 2, a partition 37 is assembled between the upper base 36 and the bottom shell 34. The connecting arm 1 includes a connector 11 sleeved on the outer layer of the partition 37 and rotating around the outer ring of the partition 37. The partition 37 is fixed to the bottom shell 34 by bolts, that is, the connecting arm 1 is rotated by rotating the connector 37. A second damping component 38 is provided near the edge of the upper end of the partition 37. The second damping component 38 includes an upper compartment 381. An upper spring 382 is provided on the inner wall of the upper compartment 381. An upper damping block 383 with a tapered end is provided on the outer side of the upper spring 382. An upper tooth 384 is provided on the inner side of the connector 11 to contact the upper damping block 383. Its damping effect is the same as the damping effect of rotating the knob 33. When the connector 11 rotates, the upper tooth 384 will press the upper spring 382 at the rear end of the upper damping block 383. The final damping effect of the connector 11 is obtained by the elastic action of the lower spring 352.

[0047] refer to Figure 2 , Figure 8 , Figure 9 As shown, the magnetic part 2 is further provided with a first magnet 21, which is used to magnetically fix the mobile phone. The connecting arm 1, which is composed of the internal metal sheet 12 (the metal sheet 12 can be made of a bendable material, such as aluminum-copper alloy) and the soft rubber layer 13 covering the outside of the metal sheet 12, realizes its bendability. Finally, the mobile phone holder can be adjusted in multiple directions.

[0048] In order to ensure the connection strength between the connecting arm 1 and the fixing part 3 while allowing the connecting arm 1 to be flexible, this technology also provides a zinc alloy part 14 at the connector 11 to improve the connection strength between the connecting arm 1 and the fixing part 3. The zinc alloy part 14 enhances the strength of the connection node between the connecting arm 1 and the fixing part 3, thereby reducing the damage to the connection node when the connecting arm 1 is bent.

[0049] In summary, the user's usage method for this car phone holder is as follows:

[0050] (1) Regarding the negative pressure adsorption principle: The soft rubber suction cup 31 on the fixing part 3 first contacts the concave bottom of the suction cup with the contact surface, and then the knob 33 is rotated (the knob 33 is damped by the first damping component 35 during rotation), which will drive the rotating column to move up and down, thereby driving the soft rubber suction cup 31 at the lower end to squeeze out the air, thus finally forming a negative pressure adsorption state and fixing and locking the fixing part 3.

[0051] (2) Adsorption principle of magnetic part 2: The mobile phone is adsorbed on the magnetic part 2 by magnetic attraction, and multi-angle adjustment is achieved by the rotation of its connecting arm 1 around the fixed part 3 (the connecting arm 1 is subjected to the action of the second damping component 38 during rotation) and the bendability of the connecting arm 1.
