According to fig. 1 to 9, this embodiment is a mobile terminal holder, which is operable by gravity of an article that can be placed thereon, and which can clamp a mobile terminal under the self-weight of the mobile terminal when the mobile terminal is placed on the holder, and which structurally comprises at least:
a main body part 1 which can be fixed on the surface of a driving platform or the position of an air conditioner air outlet and is suitable for fixing or supporting the bracket;
the pair of first connecting rods 4 are respectively positioned on the left side and the right side of the main body part, each first connecting rod comprises an inner end and an outer end, the outer ends are exposed out of the outer edge of the main body part, and the inner ends of the two first connecting rods are arranged in the main body part and are rotatably connected with the main body part;
the pair of second connecting rods 5 are respectively positioned on the left side and the right side of the main body part, one end of each second connecting rod is rotatably connected with the outer end of the corresponding first connecting rod at the same side, a lower supporting claw 2 is arranged at the other end of each second connecting rod, a side clamping claw 3 is arranged at the connecting position of each first connecting rod and the corresponding second connecting rod, and when the lower supporting claws move downwards under the action of the gravity of the mobile terminal, the side clamping claws on the two sides move inwards to clamp the mobile terminal.
Linkage rods 7 are respectively installed on the first connecting rods in a sliding mode, linkage sliding walls 53 matched with the linkage rods are arranged on the second connecting rods, and force application positions of the linkage rods relative to the linkage sliding walls deviate from rotating shafts of the second connecting rods and the first connecting rods, so that the linkage rods can enable the second connecting rods to reversely reset by pushing the linkage sliding walls. That is, the outer end of the linkage rod 7 is in sliding fit with the linkage sliding wall 53 and forms a transmission connection. The linkage sliding wall is an arc-shaped wall surface protruding outwards, so that the outer end of the linkage rod is in line contact with the linkage sliding wall to reduce friction resistance.
Further, the main body 1 includes a rear seat body and a front cover body fixed by screw connection or ultrasonic welding. Two bilaterally symmetrical connecting rod mounting columns 12 are formed in the rear seat body of the main body part, and the two first connecting rods are respectively and rotatably connected with the connecting rod mounting columns on the corresponding sides. And connecting rod rotating ports 13 for the first connecting rods to rotate up and down are formed at the left end and the right end of the rear seat body, and extend to the position, close to the middle, of the lower end of the rear seat body.
The inner ends of the two first connecting rods are respectively provided with linkage teeth 46, and the linkage teeth of the two first connecting rods are meshed and in transmission connection, so that the left first connecting rod and the right first connecting rod can synchronously move, the mobile phone can be located in the middle position of the left direction and the right direction of the mobile phone support, and the stability of the fixed mobile phone is ensured.
Install torsional spring 8 in the main part, the top position that lies in connecting rod erection column 12 in the main part is equipped with torsional spring erection column 11, the torsional spring cover is established on the torsional spring erection column, the both ends of torsional spring respectively with the inner looks butt of the gangbar of both sides. And a torsion spring clamping groove 71 is formed in the inner end side wall of the linkage rod, and the end part of the torsion spring is abutted against the torsion spring clamping groove.
Referring to fig. 7 and 8, the force application position of the linkage rod relative to the linkage sliding wall deviates from the rotation axis of the second connecting rod and the first connecting rod, when the lower end of the second connecting rod is far away from the first connecting rod to rotate, the linkage sliding wall pushes the linkage rod to slide towards the main body, and when the second connecting rod is not subjected to an external force, the linkage rod slides away from the main body under the elastic force of the torsion spring, so that the linkage sliding wall 53 is pushed to enable the second connecting rod to reversely reset.
If the thickness of the main body needs to be designed to be smaller, and the number of turns of the winding part of the torsion spring may need to be reduced, the torsion spring may be designed to have a structure as shown in fig. 10, which has two winding parts wound in a spiral shape, each winding part extends out of a support arm connected with the linkage rod, and the two winding parts are connected through a connection arm. Correspondingly, two torsion spring mounting columns 11 which are matched and spliced with the winding part are symmetrically arranged in the main body part. The torsion spring shown in fig. 10 can be symmetrically split into two independent torsion springs which are symmetrical left and right, but the torsion spring shown in fig. 10 is more convenient to install in view of installation.
In addition, as shown in fig. 11, the torsion spring may be replaced by a pressure spring, when the elastic body is a pressure spring, two ends of the pressure spring may be inserted or sleeved between the inner ends of the two linkage rods, and the middle portion of the pressure spring is located below the connecting rod mounting post 12, and preferably, a limiting portion is disposed in the main body portion corresponding to the middle portion of the pressure spring to guide the direction of the pressure spring when the pressure spring is deformed. So as to ensure that the pressure spring can drive the first connecting rod and the second connecting rod to reset. In contrast, the installation of the torsion spring is easier and the structure is more stable than the pressure spring.
Furthermore, a connecting rope for limiting the distance between the lower supporting claws at two sides is fixedly connected between the two second connecting rods. The connecting rope is soft yarn or elastic rope, and two ends of the connecting rope are clamped in the step hole at the lower end of the second connecting rod through knots. The connecting rope prevents the distance between the two lower supporting claws from being too large, so that the mobile phone can slide down from the two lower supporting claws in the process of placing the mobile phone on the mobile phone support.
Or as shown in fig. 12, the two second connecting rods are set to be in a state that the lower ends are staggered, so that the lower supporting claws arranged on the second connecting rod on the left side are positioned on the right side, the lower supporting claws arranged on the second connecting rod on the right side are positioned on the left side, the two lower supporting claws move in opposite directions when being subjected to downward pressure, the two lower supporting claws abut against each other when moving in opposite directions to a limit state, the condition that the horizontal distance between the two lower supporting claws is too large cannot occur, and the mobile phone cannot slide down from the two lower supporting claws under the condition that the connecting rope is omitted.
