[0003] However, the current mobile phone holder still has the following problems when in use:

[0004] 1. As mobile phones come in different sizes and thicknesses, the positions of their mobile phone interfaces are also different. Current mobile phone holders either do not have a position for installing and locating the mobile phone charging / connector, which requires the mobile phone charging / connector to be connected to the mobile phone after the mobile phone is fixed. The operation is complicated and inconvenient, and the interface and connector cannot be accurately aligned, which can easily lead to problems such as misalignment between the connector and the mobile phone interface, thereby causing damage to the connector / interface. Alternatively, the position of the mobile phone charging / connector on the mobile phone holder is fixed and cannot be applied to more types of mobile phones.

[0005] 2. The current mobile phone holders, especially those used in cars, are cumbersome to operate and difficult to plug and unplug the phone with one hand. It is easy for the phone to not be quickly disassembled and assembled, and the mobile phone holder to tilt or fall. It is not smooth and stable enough. Utility Model Content

[0029] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-6 , the utility model embodiment includes:

[0031] An adjustable mobile phone holder, the structure of which includes: a front fixing cover 101, a rear fixing cover 102, a clamping arm 2, a clamping arm pulley 3, a seesaw 4, a pressure rod 5, a composite pressure arm 6, a synchronous gear 7, a synchronous rack 8, a connector platform 9, a platform connecting seat 10, a locking mechanism 11, and a device connector (such as a charging interface or other connecting mechanism) 12.

[0032] The front fixing cover is connected to the rear fixing cover to form a bracket body 1 .

[0033] The two clamping arms are relatively arranged on both sides of the bracket body to clamp or release the mobile phone 13. The clamping arm pulley is rotatably arranged at the bottom of the clamping arm, so that the mobile phone and the clamping arm pulley form rolling friction to reduce the resistance of the movement direction caused by different surface textures or materials when the mobile phone moves downward or upward, which is convenient for plugging and unplugging. The extension part 21 integrally arranged on the inner side of the clamping arm is movably arranged in the movable cavity in the bracket body. The two extension parts are distributed front and back on both sides of the synchronous gear in the movable cavity, and the inner wall of each extension part is provided with the synchronous rack meshing with the synchronous gear, so that the two clamping arms can be synchronously displaced in the left and right directions through the gears to maintain synchronous opening or clamping movement.

[0034] Further preferably, the two clamp arms are inclined inwardly to form a certain angle with the bracket body, so that the mobile phone can be better attached to the bracket body, which facilitates the precise connection between the mobile phone and the device connector and prevents shaking.

[0035] Further preferably, a gear groove 22 for accommodating the synchronous gear is provided on one of the extension parts, or the grooves on the two extension parts are connected to form a gear groove, so as to maintain the stability of the connection between the synchronous gear and the extension part (synchronous rack) and prevent the synchronous gear from being displaced or loosened.

[0036] Further preferably, each of the extensions is provided with a connecting block 23, and the connecting block is connected to the bracket body via a reset spring, so that the clamping arm can be reset by the reset spring when it is not locked, so that the clamping arm remains in a clamped state.

[0037] Further preferably, a connecting and fixing portion (for example, an air outlet clip, an adhesive sheet, etc.) for fixing to a car (air outlet), a desktop, a wall, etc. is provided on the bottom of the bracket body or the side wall of the rear fixed cover plate.

[0038] A through slot 103 is horizontally arranged on the bracket body above the clamping arm, and the composite pressure arm is movably arranged in the slot.

[0039] The functions of the composite pressure arm are mainly the following two points: first, when the user connects the mobile phone to the direct body, the mobile phone will be pressed to generate downward pressure, thereby causing the product to move. In order to balance the force of the product and prevent displacement, the user can press the outwardly extending fulcrum on the composite pressure arm while pressing the mobile phone downward to apply an upward force to the bracket body, thereby preventing the bracket body from tilting or even falling off due to uneven force when installing the mobile phone; second, when the clamp arm and the composite pressure arm are tightened toward the center along the left and right directions, the inclined surface of the clamp arm applies pressure F1 to the mobile phone, and the inclined surface of the composite pressure arm applies pressure F2 to the mobile phone. The mobile phone is subjected to the combined force F of F1 and F2, and is displaced in the direction of the combined force F and is tightly attached to the front fixed cover.

[0040] Further preferably, the lower portion of the composite pressure arm is movably connected to a slot on the clamp arm via a hook 61, so that the composite pressure arm can move outward synchronously with the opening of the clamp arm to cooperate with the clamp arm to achieve clamping operations for different mobile phones.

[0041] The bottom of the bracket body is connected to the platform connecting seat, and the connector platform is movably connected to the platform connecting seat, so that the connector platform can move back and forth on the platform connecting seat. The connector is fixed on the connector platform and moves synchronously with the connector platform to adjust the position of the device connector, so that the mobile phone can be connected to the device connector more quickly and accurately.

[0042] Further preferably, the front fixing cover and the platform connecting seat are an integrated structure.

[0043] Further preferably, the protrusion 91 on the side of the connector platform is connected to the groove body on the platform connecting seat through a spring to achieve the functions of buffering adjustment and resetting.

[0044] The seesaw is rotatably arranged on the bracket body or the platform connecting seat, and the pressure rod is liftably arranged in the lifting slide groove 51 on the bracket body (rear fixed cover), and its lower end contacts and presses against the rear part of the seesaw to drive the seesaw to rotate, so that the front part of the seesaw is lifted upward, thereby lifting the mobile phone to disengage from the device connector.

[0045] When the user installs the mobile phone on the bracket body and connects the mobile phone interface with the device connector, the front part of the seesaw is pressed down by the gravity of the mobile phone. At this time, the rear part of the seesaw tilts upward under the action of the lever principle and drives the pressure rod to move upward; when the user takes the mobile phone out of the bracket body, the upward pulling force generated by pulling out the mobile phone drives the mobile phone to move. At the same time, the finger can simultaneously press the pressure rod to apply downward pressure to the rear part of the seesaw, so that the front part of the seesaw is lifted to give the mobile phone an upward thrust. This not only makes it easier to pull out the mobile phone, but also makes the bracket body more evenly stressed and less likely to move or tip over.

[0046] Further preferably, the seesaw is arranged on both sides above the connector platform.

[0047] Further preferably, a limit block for limiting the lifting limit position of the pressure rod is arranged on the bracket body or in the lifting slide groove.

[0048] The locking mechanism can lock the clamp arm and the connector platform separately or simultaneously to fix the position of the clamp arm and the device connector. The following takes locking the clamp arm and the connector platform simultaneously as an example.

[0049] The locking mechanism includes a brake shaft 111 , a platform brake pad (a platform brake pad L112 and a platform brake pad R113 ), a shaft brake pad (a shaft brake pad L114 and a shaft brake pad R115 ), a locking bolt 116 , a locking nut 117 , and a locking knob 118 .

[0050] The upper end of the brake shaft is connected to the synchronous gear, and the lower end of the brake shaft passes through the extension part and extends into the platform connecting seat. The platform brake pad is arranged on both sides of the connector platform, and the end of the locking bolt passes through the platform connecting seat and the two platform brake pads and is threadedly connected to the locking nut in the locking knob. The shaft brake pad is movably arranged on the locking bolt on the inner side of the platform brake pad, and the two shaft brake pads are arranged on both sides of the brake shaft, and the locking nut is connected to the locking knob. The connection position of the locking bolt and the locking nut is adjusted by rotating the locking knob to drive the inner end of the locking knob to squeeze the platform brake pad and the shaft brake pad, so that the shaft brake pad clamps the brake shaft and the platform brake pad clamps the shaft brake pad, thereby realizing the synchronous locking of the connector platform and the clamping arm position.

[0051] In this embodiment, the brake shaft is controlled to move by the shaft brake pads L and R to fix or release the position of the clamp arm, and the connector platform is controlled to move by the platform brake pads L and R to fix or release the position of the connector. The shaft brake pads L and R, the platform brake pads L and R are all passed through the bolts, and the nuts are rotated on the bolts to squeeze them, thereby achieving the positioning of the clamp arm, the composite pressure arm and the connector.

[0052] When it is necessary to lock the position of the clamp arm and the connection platform, first adjust the position of the connector platform according to the position of the mobile phone interface, so that the device connector can be aligned with the mobile phone interface when the mobile phone moves down; move the clamp arm and the composite pressure arm to the target position synchronously. At this time, with the movement of the clamp arm, the synchronous gear will also carry the brake shaft for synchronous axial rotation; rotate the locking knob to make the shaft brake pad approach and clamp the brake shaft to prevent the brake shaft and the synchronous gear from continuing to rotate, thereby locking the position of the clamp arm. At the same time, the platform brake pad is close to or clamps the shaft brake pad, so that the connector platform cannot move forward and backward, thereby locking the position of the connector platform.

[0053] When you need to unlock the clamping arm and the connecting platform, you only need to rotate the locking knob in the opposite direction to separate the shaft brake pad from the brake shaft and the platform brake pad respectively. The clamping arm is clamped inward and reset under the action of the reset spring, and the connector platform moves forward and backward and resets under the action of the spring.

[0054] Further preferably, the platform brake pads are movably disposed in the positioning grooves 119 on both sides of the connector platform.

[0055] Further preferably, the platform brake pad is provided with a translation limit groove 1110 allowing the locking bolt to pass through, which not only prevents the locking bolt from interfering with the forward and backward movement of the connector platform, but also can use the translation limit groove and the locking bolt to limit the forward and backward translation position.

[0056] Further preferably, the platform connecting seat is provided with a through hole 1111 allowing a locking bolt to pass through.

[0057] When adjusting the position of the clamp arm and the device connector, turn the locking knob to loosen the locking nut and the bolt so that the clamp arm and the connector platform are in a free moving state; open the clamp arm (the composite pressure arm moves synchronously) and pull the connector platform to install the mobile phone on the bracket body so that the interface of the mobile phone is connected to the device connector, loosen the clamp arm to clamp both sides of the mobile phone, and then rotate the locking knob in the opposite direction so that the locking nut (or the inner side of the locking knob) and the locking bolt squeeze the platform brake pad and the shaft brake pad to lock the position of the clamp arm and the connector platform, thereby pre-adjusting the position of the clamp arm and the connector platform according to the size of the mobile phone and the position of the interface. The next time a mobile phone of the same size is installed, no adjustment is required, thereby improving the accuracy and efficiency of plugging and unplugging.

[0058] When installing the phone, Figure 5 As shown, the user holds the mobile phone and inserts it into the pre-adjusted bracket body, and then the thumb can lift up the composite pressure arm and other fingers press down the top of the mobile phone, so that the mobile phone can move downward along the clamp arm and the clamp arm pulley and accurately plug into the device connector, thereby completing one-handed installation.

[0059] When you take out your phone, Figure 6 As shown, the user holds the mobile phone and lifts it upward, while the fingers holding the back of the mobile phone press down the pressure rod to drive the front end of the rocker to lift, so that the rocker pushes the mobile phone upward to separate from the device connector, making it easier for the mobile phone to move upward along the clamp arm and the clamp arm pulley, thereby completing one-handed removal.

[0060] The beneficial effects of the adjustable mobile phone bracket of the utility model are:

[0061] 1. Through the forward and backward movement of the connector platform, the forward and backward position of the device connector can be adjusted according to the position of the mobile phone interface, thereby achieving precise alignment between the device connector and the mobile phone interface, effectively improving the accuracy and stability of the mobile phone connection and extending the service life of the device;

[0062] 2. Through the adjustment of the clamping arm and the connector platform, it can adapt to mobile phones of different sizes and specifications, with strong versatility;

[0063] 3. The clamp arm and connector platform can be locked through the locking mechanism, which can be operated with one hand for easy operation.

[0064] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
