Technical Field

[0001] The utility model relates to a foldable mobile phone bracket with high stability. Background Art

[0002] The popularity of mobile phone holders has solved the fatigue caused by holding mobile phones for a long time, and has greatly facilitated people's lives. At present, many mobile phone holders on the market have the following problems: 1) The damping shaft is adjusted to achieve rotation connection, and then the placement angle of the mobile phone is adjusted. After long-term use, the connection part of the damping shaft of the mobile phone holder becomes loose, making it difficult for the mobile phone holder to effectively support the mobile phone. 2) The mobile phone holder occupies a certain space, which is not convenient for storage and travel. 3) In a low-light environment, when the mobile phone is placed on the mobile phone holder to watch videos, it is easy to cause visual fatigue or even vision loss. Therefore, designing a mobile phone holder with high stability, foldability and equipped with an atmosphere light can not only increase the service life of the mobile phone holder, but also facilitate carrying and improve the video viewing effect.

DETAILED DESCRIPTION

[0024] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0025] refer to Figures 1 to 5

[0026] A foldable and highly stable mobile phone holder comprises a foldable supporting base 1, a damping shaft 4 is rotatably connected to the supporting base 1, a rotationally positioned clamping mechanism 6 is provided between the damping shaft 4 and the supporting base 1, an adjusting rod assembly 8 capable of lifting and lowering adjustment is fixed to the damping shaft 4, and an adjusting supporting mechanism 9 for placing a mobile phone holder or a tablet and capable of adjusting the tilt angle is installed on the upper end of the adjusting rod assembly 8.

[0027] In this embodiment, the support base 1 includes a bearing seat 22, and a notch 23 is vertically opened at the front of the bearing seat 22 for the adjustment rod assembly 8 to flip and make way, so as to make way for the adjustment rod assembly 8 to flip downward and reduce the space occupied when folded. Three groups of foldable leg assemblies are distributed at intervals along the circumferential direction at the lower part of the bearing seat 22.

[0028] In this embodiment, the support leg assembly includes a movable rib plate 24, one end of which is rotatably connected to the inner wall of a limit groove 28 provided at the lower part of the bearing seat 22 via a pin shaft, and the other end of the movable rib plate 24 is fixed to a limit housing 25, and a pair of movable support blocks 26 that can extend outward from both ends of the limit housing 25 are slidably connected to the limit housing 25. By extending the movable support blocks 26 outward, the support area of ​​the support leg assembly can be increased, and the movable support blocks 26 that can telescopically slide can also help reduce the space occupied by storage and folding.

[0029] In this embodiment, the limiting shell 25 and the movable support block 26 are both arc-shaped, and the inner wall of the limiting shell 25 is provided with an arc-shaped groove 29. The movable support block 26 is slidably connected to the inner wall of the arc-shaped groove 29, and the inner end of the movable support block 26 is fixed with a limiting block 27 slidably connected to the inner wall of the arc-shaped groove 29; the inner side of the movable support block 26 is installed with an atmosphere light 31.

[0030] In this embodiment, in order to realize the rotational positioning of the damping shaft, the clamping mechanism 6 includes a side plate 5 fixed to one end of the damping shaft 4, an outer shell 11 is transversely fixed to the upper end of the side plate 5, and an elastically retractable latch rod 10 is passed through the outer shell 11, a first support plate 2 and a second support plate 3 are vertically fixed to the support base 1, and the damping shaft 4 is rotatably connected between the first support plate 2 and the second support plate 3, and a plurality of clamping holes 7 are provided on the first support plate 2 along the circumferential direction to match one end of the latch rod 10. After the adjustment rod assembly 8 is rotated to the desired angle, one end of the latch rod 10 is inserted into the corresponding clamping hole 7 to complete the positioning of the damping shaft 4.

[0031] In this embodiment, a baffle 12 is slidably connected to the outer shell 11 and fixedly connected to the latch rod 10. A spring 13 is provided in the outer shell 11 and is sleeved on the latch rod 10. One end of the spring 13 abuts against the baffle 12, and the other end of the spring 13 abuts against the inner wall of the end of the outer shell 11 away from the clamping hole 7, so that the latch rod 10 always has a force to move toward the clamping hole 7.

[0032] In this embodiment, the adjusting rod assembly 8 includes a sleeve 8a whose lower end is fixedly connected to the damping shaft 4, a threaded rod 8b is internally threadedly connected to the sleeve, and the upper end of the threaded rod is fixedly connected to the adjusting support mechanism. The height of the adjusting support mechanism can be adjusted by rotating the threaded rod. The connection between the threaded rod and the sleeve has a certain rotation damping, which helps to prevent the adjusting rod assembly from rotating in a tilted state and the threaded rod from rotating in a load-bearing state.

[0033] In this embodiment, the adjustment support mechanism 9 includes a longitudinal plate 15, a plurality of slots 18 with triangular cross sections are provided in the longitudinal direction of the longitudinal plate 15, the front portion of the longitudinal plate 15 is rotatably connected to the lower end of the placement plate 14 via a rotating shaft, two L-shaped limit plates 17 are fixed to the lower portion of the placement plate 14, a receiving slot 19 is provided on the back of the placement plate 14, and a support plate 16 for matching with the slot 18 is rotatably connected in the storage slot 19 via a rotating shaft. The inclination angle of the placement plate is adjusted by matching the support plate 16 with different slots.

[0034] In this embodiment, in order to ensure that the longitudinal plate 18 and the placement plate 14 can fit together when stored, a first magnetic stone 20 is fixed to the rear end of the longitudinal plate 15, and a second magnetic stone 21 that matches the first magnetic stone 14 is fixedly embedded on the back of the placement plate 14.

[0035] In this embodiment, a magnetic charging plate 30 is disposed on the surface of the placement plate 14 , a power supply interface 32 is disposed on the support seat 22 , and the magnetic charging plate 30 and the atmosphere light 31 are electrically connected to the power supply interface 32 .

[0036] Working principle: When the mobile phone stand is in use, if you need to adjust the placement angle of the mobile phone, you can first pull the latch rod 10 outward. At this time, the latch rod 10 will drive the baffle 12 to compress the spring 13, and the end of the latch rod 10 will be away from the clamping hole 7, so as to facilitate the rotation of the adjustment rod assembly 8; when the adjustment rod assembly 8 is rotated to a suitable angle, release the latch rod 10, and use the elastic force of the spring 13 to reinsert the latch rod 10 into the clamping hole 7, thereby achieving the angle fixation of the adjustment rod assembly 8, effectively avoiding the loosening of the damping shaft 4 connection after long-term use, which makes it difficult to effectively support the mobile phone and improves the support stability of the mobile phone. By inserting the foot plate 16 into the card slot 18, the foot plate 16 can be used to support the placement plate 14, so as to achieve the fixed inclination angle of the placement plate 14; by setting the storage slot 19, the foot plate 16 can be conveniently stored. By setting the notch 23, the entire adjusting rod assembly 8 can be easily rotated 180 degrees; by using the sliding connection between the limit block 27 and the arc groove 29, the movable support block 26 can be easily stored in the limit shell 25; by rotating the movable rib 24, the storage space of the mobile phone holder is saved and the portability of the mobile phone holder is improved.
