Description

Technical Field

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

[0002] With rapid economic development and the continuous improvement of people's living standards, smartphones have become an essential part of daily life and entered thousands of households. In recent years, people have become increasingly inseparable from their mobile phones in their daily lives, especially for navigation, music playback, and other purposes. Since drivers of bicycles, motorcycles, and other vehicles need to hold the handlebars with both hands, phone holders have been designed to allow drivers to conveniently use their phones for navigation and other functions without affecting driving.

[0003] Current phone holders typically use two clamping arms to hold the phone in place. These arms are connected to a drive screw and a driven screw, respectively. The drive screw directly engages with the driven screw via threads. As the drive screw moves, the area of ​​the threaded engagement between the drive screw and the driven screw changes. When the two clamping arms are far apart, the area of ​​the threaded engagement between the drive screw and the driven screw is smaller, resulting in poor stability of the two clamping arms and making them prone to wobbling.

Detailed Implementation

[0031] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments thereof. Please refer to... Figures 1 to 4 One embodiment of this utility model provides a retractable and lockable stable car phone holder, including: a base 10, a phone clamping module 20 and a fixing bracket 30.

[0032] The base 10 has a movable channel 11, within which a first internal thread portion 12 and a second internal thread portion 13 extending along the movable channel 11 are formed. The mobile phone clamping module 20 includes a first clamping arm 21, a cam locking member 22, a second clamping arm 23, a drive screw 24, a driven screw 25, several first elastic members 26, and several second elastic members 27. The drive screw 24 is movably inserted into the movable channel 11 and threadedly engaged with the first internal thread portion 12. The driven screw 25 is movably inserted into the movable channel 11 and threadedly engaged with the second internal thread portion 13. The drive screw 24 and the driven screw 25 are drivenly connected, and the drive screw 24 and the driven screw 25 can approach and move away from each other. The first clamping arm 21 and the second clamping arm 23 are respectively disposed on both sides of the base 10. The first clamping arm 21 is connected to the drive screw 24, and a rotating part is rotatably disposed on the driven screw 25. The rotating seat 251 and the second clamping arm 23 are movably mounted on the rotating seat 251, and can move closer to and away from the first clamping arm 21 relative to the rotating seat 251 along the axial direction of the driven screw 25. The cam locking member 22 is rotatably mounted on the driven screw 25 and is located on the side of the second clamping arm 23 away from the first clamping arm 21. The cam locking member 22 is provided with a pressing part 221. The first elastic member 26 is connected to the base 10 and the first clamping arm 21 respectively, and the second elastic member 27 is connected to the base 10 and the second clamping arm 23 respectively. When the driving screw 24 rotates, the driving screw 24 moves along the first internal thread 12 and drives the driven screw 25 to rotate. The driven screw 25 moves along the second internal thread 13. When the cam locking member 22 rotates, the pressing part 221 can press the second clamping arm 23 against the first clamping arm 21. The fixed bracket 30 is connected to the base 10 and is used to fix it on the vehicle.

[0033] The working principle of a retractable and locking stable car phone holder according to one embodiment of the present invention is explained below:

[0034] The phone is placed on the first clamping arm 21 and the second clamping arm 23. Then, the drive screw 24 is rotated, causing it to move along the first internal thread 12 toward the driven screw 25. This causes the first clamping arm 21 to move toward the second clamping arm 23. At this time, the first elastic element 26 undergoes elastic deformation. When the drive screw 24 rotates, it will drive the driven screw 25 to rotate, causing the driven screw 25 to also move along the second internal thread 13 toward the drive screw 24. The driven screw 25 drives the second clamping arm 23 toward the first clamping arm 21 through the cam locking element 22. At this time, the second elastic element 27 undergoes elastic deformation. The first clamping arm 21 and the second clamping arm 23 move synchronously to clamp the phone. After clamping the phone, the cam locking element 22 rotates, causing the pressing part 221 to move toward the second clamping arm 23 and press the second clamping arm 23 against the phone. This further presses the phone with the second clamping arm 23, locking it firmly and preventing it from easily coming loose.

[0035] When it is necessary to remove the phone, the cam locking member 22 is rotated so that the pressing part 221 rotates away from the second clamping arm 23. Then the drive screw 24 is rotated so that the drive screw 24 moves away from the driven screw 25 along the first internal thread 12. The elastic force of the first elastic member 26 will drive the first clamping arm 21 away from the second clamping arm 23. When the drive screw 24 rotates, it will drive the driven screw 25 to rotate, so that the driven screw 25 also moves away from the drive screw 24 along the second internal thread 13. The elastic force of the second elastic member 27 will drive the second clamping arm 23 away from the first clamping arm 21, thereby realizing the synchronous movement of the first clamping arm 21 and the second clamping arm 23 to release the phone.

[0036] When the driven screw 25 rotates, the rotating seat 251 remains stationary, thereby maintaining the angle of the second clamping arm 23 relative to the first clamping arm 21. In this embodiment, the rotating seat 251 is provided with an inner cavity 2511. The end of the driven screw 25 is rotatably disposed within the inner cavity 2511 of the rotating seat 251 and cannot move radially or axially relative to the rotating seat 251. The driven screw 25 can only rotate relative to the rotating seat 251, thereby enabling the driven screw 25 to drive the rotating seat 251 to move, and thus drive the second clamping arm 23 and the cam locking member 22 to move.

[0037] Since the drive screw 24 mainly moves along the movable channel 11 through the transmission of the first internal thread 12, as long as it is within the stroke range, the drive screw 24 and the first internal thread 12 are fully connected, and the connection area between the drive screw 24 and the first internal thread 12 will not change due to the movement of the drive screw 24. Similarly, the driven screw 25 mainly moves along the movable channel 11 through the transmission of the second internal thread 13. As long as it is within the stroke range, the driven screw 25 and the second internal thread 13 are fully connected, and the connection area between the driven screw 25 and the second internal thread 13 will not change due to the movement of the driven screw 25. Since the connection area between the drive screw 24 and the first internal thread 12 and the connection area between the driven screw 25 and the second internal thread 13 will not change, the movement of the drive screw 24 and the driven screw 25 is relatively stable, and the positions of the first clamping arm 21 and the second clamping arm 23 are also more stable.

[0038] Moreover, since the position of the first internal thread 12 remains unchanged, the position of the drive screw 24 supported remains unchanged, the position of the second internal thread 13 remains unchanged, and the position of the driven screw 25 supported remains unchanged, the stability of the movement of the drive screw 24 and the driven screw 25 is better.

[0039] In some alternative embodiments, a connecting portion 241 is formed on the drive screw 24, and a connecting hole 252 extending axially along the driven screw 25 is provided on the driven screw 25. The connecting portion 241 slides with the connecting hole 252 and is circumferentially limited by the connecting hole 252, so that the connecting portion 241 cannot rotate relative to the connecting hole 252. When the drive screw 24 and the driven screw 25 move closer and further apart, the connecting portion 241 can move along the connecting hole 252, and the drive screw 24 can drive the driven screw 25 to rotate synchronously through the connecting portion 241 and the connecting hole 252.

[0040] In some alternative embodiments, the cross-section of the connecting portion 241 is polygonal, and the cross-section of the connecting hole 252 matches the cross-section of the connecting portion 241. In this embodiment, the cross-section of the connecting portion 241 is a regular hexagon. Of course, the connecting portion 241 can also use other suitable methods to achieve circumferential limiting fit with the connecting hole 252, and this example is not limited.

[0041] To facilitate the formation of the first internal thread 12 and the second internal thread 13, in some optional embodiments, a first nut 14 and a second nut 15 are provided within the movable channel 11. The first internal thread 12 is formed inside the first nut 14, and the second internal thread 13 is formed inside the second nut 15. In this embodiment, two limiting grooves are provided within the movable channel 11, and the first nut 14 and the second nut 15 are correspondingly matched with the two limiting grooves for limiting engagement.

[0042] In some alternative embodiments, a rotary knob 242 is provided on the drive screw 24. The rotary knob 242 is located on the side of the first clamping arm 21 away from the second clamping arm 23. The drive screw 24 is rotatably engaged with the first clamping arm 21. The user can drive the drive screw 24 to rotate by turning the rotary knob 242. The first elastic member 26 presses the first clamping arm 21 against the rotary knob 242. The rotary knob 242 restricts the first clamping arm 21 to the side away from the second clamping arm 23. The drive screw 24 drives the first clamping arm 21 to move by rotating the rotary knob 242.

[0043] In some alternative embodiments, a stop portion 16 is provided at one end of the movable channel 11 facing the first clamping arm 21, and a limiting portion 243 is provided on the side of the drive screw 24. The limiting portion 243 is located in the movable channel 11 and cooperates with the stop portion 16 to limit the maximum distance that the drive screw 24 can move away from the driven screw 25. When the drive screw 24 moves away from the driven screw 25 to the maximum limit distance, the limiting portion 243 will abut against the stop portion 16.

[0044] In some optional embodiments, the base 10 has multiple first sliding holes 17 and multiple second sliding holes 18 on both sides. The first clamping arm 21 and the second clamping arm 23 are each provided with multiple guide posts 211. The guide posts 211 of the first clamping arm 21 slide in conjunction with the first sliding holes 17, thereby improving the movement stability of the first clamping arm 21. The guide posts 211 of the second clamping arm 23 slide in conjunction with the second sliding holes 18, thereby improving the movement stability of the second clamping arm 23. The first elastic element 26 includes multiple first springs correspondingly disposed in the first sliding holes 17. The first springs are connected to the guide posts 211 of the first clamping arm 21. The multiple first springs help to improve the balance of the elastic force on the first clamping arm 21. The second elastic element 27 includes multiple second springs correspondingly disposed in the second sliding holes 18. The second springs are connected to the guide posts 211 of the second clamping arm 23. The multiple second springs help to improve the balance of the elastic force on the second clamping arm 23.

[0045] Please see Figure 2 and Figure 5 In some alternative embodiments, the retractable and lockable sturdy in-vehicle phone holder also includes a phone holder assembly 40; the phone holder assembly 40 includes a base 41, a lifting guide rod 42, a clamping member 43, and a locking screw 44. The base 41 is arranged between the first clamping arm 21 and the second clamping arm 23 and is located at the bottom of the base 10. The lifting guide rod 42 is disposed on the base 41 and slides with the base 41. The clamping member 43 is movably disposed on the base 41 and is located on one side of the lifting guide rod 42. The locking screw 44 is threadedly connected to the base 10 and drivenly connected to the clamping member 43. The clamping member 43 can press the lifting guide rod 42 toward the base 10 and away from the lifting guide rod 42 under the drive of the locking screw 44. Users can twist the locking screw 44 to move the clamping member 43 closer to and away from the lifting guide rod 42. When the clamping member 43 presses the lifting guide rod 42 onto the base 10, the lifting guide rod 42 is pressed and cannot be raised or lowered, thus locking the position of the base 41. When the clamping member 43 moves away from the lifting guide rod 42, the lifting guide rod 42 can be raised or lowered. At this time, the base 41 can be raised or lowered relative to the base 10 to adjust its height, thus adapting to mobile phones of different sizes.

[0046] To facilitate the user's turning of the locking screw 44, in some optional embodiments, a locking knob 45 is provided on the locking screw 44.

[0047] To improve the stability of the base 41, in some optional embodiments, the base 41 is provided with a plurality of lifting guide rods 42.

[0048] Please see Figure 6The specific structure of the fixed bracket 30 can be designed according to actual needs. For example, in some optional embodiments, the fixed bracket 30 includes multiple elastic buffers 31, a first ball joint 32, an intermediate adapter 33, a second ball joint 34, and a fixed clamping plate 35. The elastic buffers 31 are connected between the first ball joint 32 and the base 10. The first ball joint 32 is rotatably engaged with the intermediate adapter 33, and the second ball joint 34 is rotatably engaged with the intermediate adapter 33. The fixed clamping plate 35 is connected to the second ball joint 34 by multiple locking bolts. A space for clamping the pole of the vehicle is formed between the fixed clamping plate 35 and the second ball joint 34. The fixed clamping plate 35 can be moved closer to or away from the second ball joint 34 by rotating the locking screw 44. Of course, the structure of the fixed bracket 30 is not limited to this, and those skilled in the art can also choose other suitable structures based on the teachings of this utility model.
