Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a vehicle mount bracket. Background Technology

[0002] A car phone holder is a vehicle accessory designed specifically for drivers. It secures smartphones and other electronic devices to locations inside the car, such as air vents, dashboard, door panels, or windshield, allowing for safe and convenient use of navigation, phone calls, or music playback while driving. These holders typically feature adjustable clamps and a rotating axis to accommodate phones of different sizes and the driver's line of sight. They offer stable mounting and easy one-handed operation, reducing the risk of driver distraction and improving driving safety.

[0003] In the market, car phone holders typically only offer adjustment in a single direction of rotation, such as rotation around a vertical axis. This makes it difficult for users to flexibly adjust the position of their electronic devices. The limited freedom of the adjustment arm restricts its adjustment range and makes it inconvenient for users to adjust to a suitable installation angle. Utility Model Content

[0048] This utility model proposes a vehicle mount, aiming to provide a vehicle mount with a wider adjustment range and greater flexibility of use. Figures 1 to 9 This is a schematic diagram of one embodiment of the vehicle mount bracket provided by this utility model.

[0049] Please refer to Figures 1 to 9 This utility model proposes a vehicle mount 100, including an electric suction cup 1, a first adjusting arm 2, a second adjusting arm 3, and a magnetic suction cup 4. The electric suction cup 1 has a silicone suction cup 11 on one side, and a rotating platform 5 is rotatably provided on the side opposite to the silicone suction cup 11. The first adjusting arm 2 is rotatably provided on the rotating platform 5. The end of the first adjusting arm 2 away from the rotating platform 5 is provided with a first rotating shaft 22. The vehicle mount 100 also includes a mounting base 21, which is rotatably provided on the first adjusting arm 2 via the first rotating shaft 22. The mounting base 21 is provided with a second rotating shaft 6, which is perpendicular to the axis of the first rotating shaft 22. The second adjusting arm 3 is provided on the second rotating shaft 6 and can rotate relative to the mounting base 21. The magnetic suction cup 4 is provided on the end of the second adjusting arm 3 away from the mounting base 21.

[0050] This utility model proposes a vehicle mount 100, which includes an electric suction cup 1, a first adjusting arm 2, a second adjusting arm 3, and a magnetic suction cup 4. The electric suction cup 1 is provided with a rotating platform 5. The first adjusting arm 2 is located on the rotating platform 5 and can rotate relative to the electric suction cup 1 via the rotating platform 5. The first adjusting arm 2 can also rotate relative to the rotating platform 5. The end of the first adjusting arm 2 away from the rotating platform 5 is provided with a rotatable mounting base 21. The second adjusting arm 3 is located on the mounting base 21. The second adjusting arm 3 can rotate relative to the mounting base 21, and the second rotating shaft 6 that enables the rotation is set perpendicular to the first rotating shaft 22. This ensures that the second adjusting arm 3 has two degrees of freedom of rotation relative to the first adjusting arm 2, thereby further expanding the adjustment range, improving the overall flexibility of the mount, and making it easier for the user to adjust to a suitable angle.

[0051] Moreover, both ends of the vehicle mount 100 proposed in this utility model can be attached to the vehicle interior. When the electric suction cup 1 is attached to the vehicle interior, the magnetic suction cup 4 is used to attach and fix the mobile phone; when the magnetic suction cup 4 is fixed to a ferromagnetic structure inside the vehicle, the electric suction cup 1 is used to attach and fix the mobile phone, which has higher operational flexibility.

[0052] Taking the example of an electric suction cup 1 adhering to the interior of a vehicle and a magnetic suction cup 4 adhering to electronic devices such as mobile phones, to further improve the flexibility of the bracket and facilitate users to precisely adjust the orientation angle of the electronic devices, the end of the second adjusting arm 3 away from the mounting base 21 is provided with a ball head. Correspondingly, one side of the magnetic suction cup 4 is configured as a ball head sleeve 41. For details, please refer to further reference. Figure 3 The ball head is hinged to the ball head sleeve 41. The ball head sleeve 41 has an open cavity at one end, and the ball head is embedded in the cavity and rotates with the inner wall of the cavity. The ball head can be interference-fitted with the cavity, so that the mounting plate can be suspended at a certain angle after rotating. In one embodiment of the present invention, the ball head sleeve 41 is made of elastically deformable material, and a notch is provided at the opening of the cavity. An adjusting nut (not shown in the figure) is screwed to the outside of the ball head sleeve 41. The inner wall of the adjusting nut is provided with a protrusion that abuts against the periphery of the cavity opening. By rotating, the adjusting nut can drive the periphery of the cavity opening to deform, thereby clamping or releasing the ball head, realizing the fixing and releasing of the ball head.

[0053] In one embodiment of this utility model, the second adjusting arm 3 is rotatably connected to one end of the mounting base 21 by a screw connection. Since the adjustment and rotation of the second adjusting arm 3 will inevitably cause the bolt to rotate, thereby causing the bolt to loosen, the second adjusting arm 3 is rotatably mounted to the mounting base 21 by a specially designed second rotating shaft 6. For details, please refer to further description. Figure 4 The second adjusting arm 3 is provided with a mounting hole 32, and a mounting step 321 is provided circumferentially around the mounting hole 32. The second rotating shaft 6 includes a first fixing bolt 61 and a first flat bearing 62. The first fixing bolt 61 passes through the mounting hole 32, and one end of the first fixing bolt 61 is screwed to the mounting base 21. The two ends of the first flat bearing 62 abut against the nut 611 of the first fixing bolt 61 and the lower bottom surface of the mounting step 321, respectively. The first flat bearing 62 has an outer ring that can rotate relative to the first fixing bolt 61, and the outer peripheral wall of the outer ring abuts against the inner peripheral wall of the mounting hole 32. In this way, the first flat bearing 62 can separate the moving part (i.e., the second adjusting arm 3) and the fixed part (i.e., the first fixing bolt 61). The flat bearing transmits the load through rolling or sliding contact, thereby reducing the tendency of the bolt to loosen due to vibration or dynamic load. This isolation effect of the flat bearing can protect the bolt from repeated stress, maintain the tightness of the connection, and prevent the bolt from loosening due to fatigue or relaxation.

[0054] To provide better damping feel during adjustment and optimize user experience, the second pivot 6 also includes a first disc-shaped washer 63. For details, please refer to further details. Figure 4 The first disc-shaped washer 63 abuts against both the nut 611 and the first flat bearing 62. The first disc-shaped washer 63 has a special tapered design, providing better damping compared to flat washers and storing potential energy after deformation under load. When the bolt loosens, the stress distribution of the disc-shaped washer decreases uniformly from the inside out, achieving a low-stroke, high-compensation-force effect. Especially when used in a stacked configuration, the surface friction damping effect significantly enhances the absorption of impact and dissipation of energy. Furthermore, the disc-shaped washer provides superior buffering and vibration absorption capabilities compared to flat washers under vibration conditions.

[0055] To optimize the damping feel when the first adjusting arm 2 rotates relative to the electric suction cup 1, the electric suction cup 1 incorporates a rotational damping structure 7. For details, please refer to further documentation. Figure 5 and Figure 6In this embodiment, the rotating platform 5 is provided with a first mounting groove facing the silicone suction cup 11, and the electric suction cup 1 is provided with a second mounting groove facing the rotating platform 5. The first fixing plate 71 and the second fixing plate 72 in the rotation damping structure 7 are respectively fixedly installed in the first mounting groove and the second mounting groove and remain stationary, equivalent to the mounting groove being installed. A second disc-shaped gasket 73 is provided between the first fixing plate 71 and the second fixing plate 72. By making the first fixing plate 71 and the second fixing plate 72 tightly abut against the second disc-shaped gasket 73, the second disc-shaped gasket 73 can be deformed to apply a reverse force to the first fixing plate 71 and the second fixing plate 72 to increase the friction with the first fixing plate 71 and the second fixing plate 72 respectively, thereby providing better damping. Furthermore, in one embodiment of this utility model, the rotational damping structure 7 further includes a friction plate 74. The friction plate 74 is sleeved on the electric suction cup 1 for mounting the second fixing bolt 51 of the rotary table 5. The first fixing plate 71 has a mounting shaft on the side facing the second fixing plate 72. The friction plate 74 is sleeved on the mounting shaft and remains relatively stationary with the mounting shaft. That is, the friction plate 74 and the first fixing plate 71 maintain the same motion trajectory. One side of the friction plate 74 abuts against the second fixing plate 72, and the side of the friction plate 74 facing the second fixing plate 72 is configured as a rough surface. Correspondingly, the side of the second fixing plate 72 facing the friction plate 74 is also configured as a rough surface. The two rough surfaces abut against each other, thereby increasing the rotational resistance when the rotary table 5 rotates, so as to provide better damping. It should be noted that the rough surface can be composed of multiple tiny protrusions or covered by a material with a higher surface roughness. This invention does not limit this. In one embodiment, the friction plate 74 has multiple first grooves 741 facing the second fixing plate 72, and the second fixing plate 72 has multiple second grooves 721 facing the friction plate 74. By providing multiple grooves, an uneven contact surface is formed, thereby increasing its frictional resistance. Furthermore, by configuring the contact surface as grooves, the damping sensation can be ensured to remain continuously while being less affected by frictional loss, thus maintaining the stability of the damping effect.

[0056] To secure the first fixing piece 71 and the second fixing piece 72, the inner wall of the first mounting groove is provided with at least one first limiting protrusion, and the outer wall of the first fixing piece 71 is provided with at least one first limiting groove, with the first limiting protrusion abutting against and limiting the first limiting groove. The inner wall of the second mounting groove is provided with at least one second limiting protrusion 53, and the outer wall of the second fixing piece 72 is provided with at least one second limiting groove, with the second limiting protrusion 53 abutting against and limiting the second limiting groove. The cooperation between the limiting groove and the limiting protrusion prevents the first fixing piece 71 from rotating relative to the first limiting groove and prevents the second fixing piece 72 from rotating relative to the second limiting groove.

[0057] In the technical solution of this utility model, since both the magnetic suction cup 4 and the electric suction cup 1 can serve as adsorption devices that directly contact electronic devices, in order to realize more functions of the vehicle mount 100, the magnetic suction cup 4 is provided with a first wireless charging coil 44 and the electric suction cup 1 is provided with a second wireless charging coil 124. For details, please refer to further description. Figure 7 and Figure 9 The first wireless charging coil 44 is positioned facing the magnetic suction cup 4, and the second wireless charging coil 124 is positioned facing the silicone suction cup 11. In this way, whether the magnetic suction cup 4 or the electric suction cup 1 acts as the direct contact device for the phone, wireless charging of electronic devices can be achieved. This enables a "dual-purpose" function, serving as both a phone holder and a wireless charger, allowing users to charge their phones while navigating and ensuring they have a full battery. Furthermore, the wireless charging coil design simplifies the charging process and improves ease of use.

[0058] In one embodiment of this invention, to prevent overheating during mobile phone charging and its impact on the lifespan of the mobile phone battery 17, the magnetic chuck 4 has multiple heat dissipation fins 42 on the side facing away from the adsorption surface. These fins effectively dissipate heat generated during wireless charging. By increasing the heat dissipation area, they accelerate heat conduction and dissipation, thereby reducing the temperature of the mobile phone and the wireless charging coil, ensuring charging efficiency and stability. Furthermore, the heat dissipation fins 42 effectively suppress the impact of high temperatures on the performance of the wireless charging coil and reduce potential safety risks, improving the user experience.

[0059] To achieve positioning and fixing of mobile phones or other electronic devices, the magnetic chuck 4 is equipped with a magnetic ring 45, and the electric chuck 1 is equipped with a positioning magnetic ring 123. For details, please refer to further documentation. Figure 7 and Figure 9 The magnetic ring 45 and positioning magnetic coil 123 provide strong attraction force and long attraction distance, allowing the phone to be firmly fixed on the holder and reducing the impact of vehicles on device stability under complex road conditions. Secondly, the magnetic ring 45 has minimal interference and will not affect the internal electronic components of the phone. Due to the special orientation of the magnetic ring 45, precise positioning can be achieved, reducing positioning deviation and thus improving the efficiency and accuracy of wireless charging. The design of the magnetic ring 45 facilitates rapid centering and positioning of electronic devices.

[0060] In the technical solution of this utility model, the electric suction cup 1 can be used as a mounting base for vehicle interiors such as door panels, dashboards, and windows, and can also be used to adsorb electronic devices such as mobile phones and tablets as an adsorption device. This utility model does not limit this. In one embodiment of this utility model, the electric suction cup 1 includes a housing 12, a sealed adapter box 13, an air pump 14, and a puncture valve 15. The housing 12 has a receiving cavity with an opening at one end, and the opening is located at the center of the silicone suction cup 11. When a mobile phone or other object covers the silicone suction cup 11, the silicone suction cup 11, the sealed adapter box 13, and the hand... The back cover of the device together form a vacuum area. The air pump 14 is connected to the sealed adapter box 13 via a hose 142, which is also connected to the vacuum area. When an object comes into contact with the silicone suction cup 11, it presses down the push rod 19 located in the middle of the silicone suction cup 11. The push rod 19 drives the pressure plate 192 to move towards the side closer to the micro switch 191 until the micro switch 191 is triggered. The circuit board 18 is electrically connected to the air pump 14 and sends an electrical signal to control the air pump 14 to start working, that is, to evacuate the vacuum area to create a negative pressure, thereby ensuring that the object can be firmly attached to the surface of the electric suction cup 1. The end of the push rod 19 away from the silicone suction cup 11 is equipped with a return spring 193. When the push rod 19 descends, the return spring 193 is compressed. When the user controls the electric suction cup 1 to close, the return spring 193 will push the push rod 19 to reset under the action of elastic potential energy.

[0061] It should be noted that the air pump 14 can be either a diaphragm pump or a plunger pump; this invention does not limit the choice. In one embodiment of this invention, the air pump 14 is a diaphragm pump. The diaphragm pump achieves gas intake and exhaust by changing the volume within the pump chamber. When the motor drives the compressor to rotate, the diaphragm reciprocates up and down within the pump chamber. During this process, the volume of the pump chamber changes accordingly: when the diaphragm moves upward, the volume of the pump chamber increases, creating a negative pressure, and gas is drawn in through the inlet; when the diaphragm moves downward, the volume of the pump chamber decreases, and the gas is compressed and pushed towards the outlet for exhaust. Through the continuous reciprocating motion of the diaphragm, the diaphragm pump vacuum pump achieves continuous gas intake and exhaust, thereby achieving a vacuum effect. The air pump 14 is mounted inside the housing 12 via a pump bracket 141, thus achieving fixed support.

[0062] To facilitate user access, the sealed adapter box 13 is connected to a puncture valve 15. The end of the puncture valve 15 away from the sealed adapter box 13 is provided with a pressing part 151. The pressing part 151 is exposed on the outside of the housing 12. Users can control the puncture valve 15 to open by pressing the pressing part 151, thereby connecting the vacuum area with the outside world and creating a contact adsorption state, which facilitates the handling of mobile phones and other electronic devices.

[0063] In the technical solution of this utility model, the housing 12 of the electric suction cup 1 is divided into an upper housing 121 and a lower housing 122, which facilitates disassembly and assembly for replacement or maintenance of internal components. The electric suction cup 1 has a reserved first charging port 181, and a battery 17 is installed inside the housing 12, which can be charged via a wired connection. In addition, the electric suction cup 1 also includes a photovoltaic module 16, which is located on one side of the housing 12 and electrically connected to the battery 17 inside the housing 12. It can generate electricity through solar energy. This design achieves the dual advantages of environmental protection and energy self-sufficiency. It reduces dependence on traditional electricity and conforms to the concept of green environmental protection. Secondly, when the vehicle is parked or used outdoors during the day, the phone holder can maintain its suction force without additional power, increasing the convenience of use.

[0064] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention.
