Description

Technical Field

[0001] The utility model relates to the field of mobile terminal bracket technology, in particular to a magnetic bracket. Background Art

[0002] With the popularity of mobile terminals such as smart phones, the frequency of using various applications on mobile terminals has gradually increased. In order to free hands to watch mobile phones and other mobile terminals, mobile phone and other mobile terminal holders have solved this problem well. Traditional mobile phone and other mobile terminal holders are mechanical structure holders, which are fixed and stable but have a complex structure. It is also inconvenient to take out mobile phones and other mobile terminals. For this reason, magnetic holders have been born one after another.

[0003] For example, China Publication No. CN219459128U discloses a magnetic mobile phone holder, which includes a base, a support rod and a support mainboard. One end of the support rod is rotatably connected to the support mainboard, and the other end is rotatably connected to the base. The support mainboard is provided with a magnetic component, so that the mobile phone can be magnetically fixed by magnetic attraction. Although it can absorb the mobile phone by magnet, when the magnetic attraction of the magnet is too strong, the mobile phone is not easy to remove after being absorbed by the magnetic holder; when the magnetic attraction of the magnet is weak, the mobile phone is easy to fall off the magnetic holder when the magnetic holder vibrates, especially when the magnetic holder is installed on a bicycle as a riding holder, the mobile phone is easy to fall off after the magnetic holder is bumped.

[0004] Therefore, it is necessary to develop a new technology to solve the above problems. Utility Model Content

By adjusting the position of the movable seat 50, the distance between the second magnetic component 30 and the mobile terminal placed on the placement area is adjusted, thereby adjusting the magnetic attraction force of the magnetic component on the mobile terminal. When the mobile terminal needs to be stably adsorbed, the second magnetic component 30 is moved to the first position close to the placement area by rotating the operating member 40, so that the second magnetic component 30 and the first magnetic component 20 can jointly adsorb the mobile terminal, so that the mobile phone can be firmly adsorbed on the bracket body 10. When the mobile terminal needs to be removed, the second magnetic component 30 is moved to the second position away from the placement area by rotating the operating member 40 in the opposite direction, thereby weakening the magnetic attraction force of the second magnetic component 30 on the mobile terminal, so as to facilitate the removal of the mobile terminal from the bracket body 10.

The first magnetic component 20 is coaxially arranged with the second magnetic component 30, and the movable seat 50 is located in the middle of the bracket body 10. When the movable seat 50 is in the first position, the second magnetic component 30 is located on the inner side of the first magnetic component 20. Specifically, when the movable seat 50 is in the first position, the first magnetic component 20 and the second magnetic component 30 are on the same plane, further increasing the magnetic attraction to the mobile phone.

[0053] like Figures 3 to 5 As shown, in this embodiment, the second magnetic attraction member 30 is fixed to one end of the movable seat 50, and the other end of the movable seat 50 has a shaft 60 extending along the radial direction of the bracket body 10, and a guide hole 11 extending along the axial direction of the bracket body 10 is provided on the outer wall of the bracket body 10, and the two ends of the shaft 60 are respectively connected to the operating member 40 through the guide hole 11; specifically, the operating member 40 is preferably a semi-annular handle for holding and rotating, and the two ends of the operating member 40 are respectively abutted against the two opposite outer walls of the bracket body 10, the shaft 60 is penetrated on the movable seat 50, and the two ends of the shaft 60 are respectively connected to the two ends of the operating member 40 after passing through the bracket body 10; both sides of the rear end of the movable seat 50 are extended with an extension convex portion 53, the extension convex portion 53 is provided with a through hole 54, and the shaft 60 is penetrated through the through hole 54.

Specifically, the inner wall of the steering groove 12 has a first vertical limiting surface 121, a transverse limiting surface 122 and a second vertical limiting surface 123 connected in sequence, the first vertical limiting surface 121 and the second vertical limiting surface 123 both extend along the axial direction of the bracket body 10, and the transverse limiting surface 122 extends from the outside to the inside along the radial direction of the bracket body 10, and the end of the operating member 40 located in the steering groove 12 is provided with adjacent steering limiting convex parts 41 and steering plane parts 42; except for the connection between the steering limiting part 41 and the steering plane part 42, the distance from each position on the surface of the steering convex part 41 to the axis of the shaft rod 60 is greater than the distance from each position on the surface of the steering plane part 42 to the axis of the shaft rod 60. The turning plane portion 42 abuts against the transverse limiting surface 122 when the second magnetic member 30 is subjected to the magnetic force of the first magnetic member 20, and the movable seat 50 is in the first position.

The first connecting hole 171 and the second connecting hole 161 are connected by screw locking, an annular positioning groove 13 is formed on the front side of the cover plate 16, and the second connecting hole 161 passes through the annular positioning groove 13. The first support plate 70 is fixed to the front side of the cover plate 16, and the guide hole 11 and the steering groove 12 are both formed on the outer side wall of the shell 15; the lower end of the steering groove 12 extends downward to form an opening to make way for the operating member 40; the connecting member 90 is connected to the rear end of the shell 15.

[0059] like Figures 1 to 5As shown, in this embodiment, the magnetic bracket is in the initial state (that is, the movable seat 50 is in the first position), the second magnetic member 30 and the first magnetic member 20 are in the same plane with respect to the magnetic surface of the mobile terminal, and the front side surface of the second support plate 80 is in the same plane with the placement area, so that the second magnetic member 30 and the first magnetic member 20 can simultaneously adsorb the mobile terminal, so that the mobile terminal can be firmly adsorbed on the placement area of ​​the bracket body 10, and the end of the operating member 40 away from the bracket body 10 is at the bottom, and the shaft 60 abuts against the upper inner wall of the guide hole 11.

Figures 8 to 10 As shown, the magnetic surfaces of the second magnetic component 30 and the first magnetic component 20 for the mobile terminal are not in the same plane, the front side surfaces of the first support plate 70 and the second support plate 80 are not in the same plane, the second magnetic component 30 is away from the placement area, and the magnetic attraction force of the second magnetic component 30 on the mobile terminal is weakened to facilitate the removal of the mobile terminal from the bracket body 10, the shaft 60 is located on the lower inner wall of the guide hole 11, the steering limit protrusion 41 on the control component 40 is against the lateral limit surface 122 of the steering groove 12, and the movable seat 50 is in the second position.

[0060] In summary, the design focus of the utility model is that it is mainly fixed to the bracket body through the first magnetic attraction member, and the second magnetic attraction member can be movably fixed to the movable seat relative to the first magnetic attraction member. When the operating member is rotated, the operating member links the movable seat to move, so that the movable seat switches between the first position and the second position. In this way, the distance between the second magnetic attraction member and the mobile terminal placed on the placement area can be adjusted by adjusting the position of the movable seat, thereby adjusting the magnetic attraction force of the magnetic attraction component on the mobile terminal. When it is necessary to stably adsorb the mobile terminal, the operating member is rotated to move the second magnetic attraction member to the first position close to the placement area, so that the second magnetic attraction member and the first magnetic attraction member can jointly adsorb the mobile terminal, so that the mobile phone can be stably adsorbed on the bracket body.
