Specifically, the gear portion of the first gear 51 is meshed with the large gear portion of the second gear 52, the pinion portion of the second gear 52 is meshed with the gear portion of the third gear 53, the pinion portion of the second gear 52 is coaxially disposed with the large gear portion of the second gear 52, the gear portion of the third gear 53 is simultaneously meshed with the rack 215, and the number of teeth of the gear portion of the third gear 53 is greater than that of the gear portion of the first gear 51, so that the transmission connection among the first gear 51, the second gear 52 and the third gear 53 is smoother by controlling the rotation speed ratio of the first gear 51, the second gear 52 and the third gear 53, thereby facilitating the first elastic member 40 to more easily drive the rack 215 to push the transmission assembly 50 to rotate.

Further, as shown in fig. 5 and 6, the first gear 51 is provided with catch grooves 511 and catch teeth 512 alternately in the circumferential direction around the axis thereof, and the catch grooves 511 and the catch teeth 512 are engaged with the lock assembly 70.

The second elastic member 60 is disposed in the housing 10, and both ends thereof are respectively coupled between the fixed shaft 116 disposed in the front case 12 and the locking assembly 70, and the locking assembly 70 is restored to an initial position by a repulsive force of the second elastic member 60.

The locking assembly 70 is disposed in the housing 10 at the front end of the transmission assembly 50, i.e. the locking assembly 70 cooperates with the first gear 51. The locking assembly 70 includes a cam member 71 and a gear member 72 that cooperate with each other. The cam member 71 and the gear member 72 are mounted on a cam member shaft 114 and a gear member shaft 115 formed in the front case 11, respectively, and the cam member shaft 114 and the gear member shaft 115 are parallel to the first gear shaft 111, the second gear shaft 112 and the third gear shaft 113, that is, the rotational axes of the first gear 51, the second gear 52, the third gear 53, the cam member 71 and the gear member 72 are parallel to each other.

The cam member 71 includes a fixing portion 711, a projecting portion 712, a first projection 713, a second projection 714, and a cam boss 715, as shown in fig. 4, 7, and 8. The fixing portion 711 is disposed at one side of the cam member 71, and mounts the second elastic member 60 together with the fixing shaft 116. A projection 712 is provided on the other side of the cam member 71 opposite to the fixing portion 711, and the projection 712 selectively engages with the engaging groove 511 and the engaging tooth 512 of the first gear 51. The first and second protrusions 713 and 714 are provided on an end surface (i.e., a front end surface) facing the gear member 72, and the first and second protrusions 713 and 714 are selectively engaged with the gear member 72. Specifically, the fixing portion 711 and the protruding portion 712 are respectively located at two opposite sides of the rotation axis of the cam member 71, the first protrusion 713 and the second protrusion 714 are respectively located at two opposite sides of the connection line between the fixing portion 711 and the protruding portion 712, and the cam shaft sleeve 715 is used for sleeving the cam member 71 on the cam member shaft 114.

When the cam member 71 is rotated by the other latch 512 beside the latch slot 511, the second protrusion 714 contacts with the gear member 72 to rotate the gear member 72, and the rotation direction of the gear member 72 is opposite to that of the cam member 71.

The gear member 72 includes a first tooth slot 721, a second tooth slot 722, and a gear bushing 723, as shown in fig. 9 and 10. The first tooth grooves 721 and the second tooth grooves 722 are alternately arranged in the circumferential direction around the axis of the gear member 72, and the adjacent first tooth grooves 721 and second tooth grooves 722 are arranged on opposite sides of the tooth portion of the gear member 72. The depth of the second spline 722 is greater than that of the first spline 721, and the first protrusion 713 of the cam member 71 is selectively engaged with the first spline 721 or the second spline 722. Gear member 72 is mounted to gear member shaft 115 by a gear sleeve 723.

The working principle of the mobile terminal clamping bracket is as follows:

as shown in fig. 11, when the user presses the first clamping member 20 once, the first protrusion 713 of the cam member 71 enters the first tooth slot 721 of the gear member 72 and is stopped by the first tooth slot 721 to limit the rotation of the cam member 71 in the clockwise direction, and the protrusion 712 is located in the slot 511 of the first gear 51 and stopped on the tooth 512, so that the first gear 51 cannot rotate in the counterclockwise direction, and finally the first elastic member 40 cannot push the first clamping member 20 to move outwards, so as to position the first clamping member 20 at the first position and cooperate with the second clamping member 30 to clamp the mobile terminal together.

When the user presses the first clamping member 20 again, the first groove 221 of the first abutting block 22 and the second groove 321 of the second abutting block 32 are relied on to provide a space for the first clamping member 20 to move inward. The other latch 512 of the first gear 51 contacts the protrusion 712 of the cam member 71 to rotate the cam member 71 in the counterclockwise direction, such that the second protrusion 714 of the cam member 71 pushes the gear member 72 to rotate in the clockwise direction, thereby causing the first protrusion 713 of the cam member 71 to enter the second slot 722, as shown in fig. 12. When the user releases the pushing of the first clamping member 20, the first elastic member 40 pushes the first clamping member 20 to move outward, and at this time, since the depth of the second gear slot 722 is greater than the depth of the first gear slot 721, the cam member 71 can rotate by a greater angle in the clockwise direction, so that the protrusion 712 is no longer stopped by the latch 512, and further the first gear 51 can rotate in the counterclockwise direction, and finally the rack 215 engaged with the third gear 53 drives the first clamping member 20 to pop out outward under the action of the first elastic member 40 to be positioned at the second position, so as to finish the clamping of the mobile terminal.

Referring to fig. 13 to 15, the structure of the mobile terminal clamping bracket according to the second preferred embodiment of the present invention is the same as that of the first preferred embodiment, and includes a housing 10, a first clamping member 20, a second clamping member 30, a first elastic member 40, a transmission assembly 50, a second elastic member 60, and a locking assembly 70, except that the first clamping arm 21 of the first clamping member 20 is a rotatable member. That is, the first clamping arm 21 includes a first clamping arm body 211 and a first sliding member 212, the first abutting block 22 is disposed on the first clamping arm body 211, the first clamping arm body 211 is mounted on the first sliding member 212 through a first rotating shaft 213 and a first torsion spring 214 sleeved on the first rotating shaft 213, and two ends of the first torsion spring 214 abut against the first clamping arm body 211 and the first sliding member 212, respectively, so that the first clamping arm body 211 can rotate outward around the first rotating shaft 213 relative to the first sliding member 212 under the action of an external force, and can return to an initial position (a position substantially perpendicular to the first sliding member 212) under the action of a restoring force of the first torsion spring 214. The first arm-clamping body 211 can rotate outwards relative to the first sliding part 212, so that the mobile terminal can be taken out more easily by pulling the first arm-clamping body 211, and convenience is greatly improved for a user.

In addition, a first roller 23 is further mounted on the first arm-clamping body 211, and the first roller 23 is pivoted to the first arm-clamping body 211 and is disposed away from the housing 10 relative to the first abutting block 22. When the mobile terminal is put in, the first roller 23 rolls with respect to the first clamp arm body 211 for guiding the mobile terminal to be clamped between the first abutting block 22 and the second abutting block 32, or guiding the mobile terminal to be released from the clamping of the first abutting block 22 and the second abutting block 32 when the mobile terminal is taken out. Of course, the portion of the first roller 23 contacting the mobile terminal may also be made of an elastic material so as to provide a deformation space when the user presses the first clamping member 20 again.

In other embodiments, the first clamping arm 31 of the second clamping member 30 can also be a rotatable member. That is, the second clamping arm 31 includes a second clamping arm body, a second sliding member, a second rotating shaft and a second torsion spring, the second abutting block 32 is disposed on the second clamping arm body, and a second roller is further mounted on the second clamping arm body, and a portion of the second roller contacting the mobile terminal may also be made of an elastic material.

The first rack 212 and the second rack 312 are respectively engaged with the third gear 53 of the transmission assembly at the upper end and the lower end, so that when the third gear 53 rotates, the first rack 212 and the second rack 312 move back to back or face to face, and the first arm-clamping body 211 and the second arm-clamping body 311 are opened and closed.

The working principle of the mobile terminal clamping bracket is as follows:

as shown in fig. 20, when the user presses the first clamping member 20 once, the first protrusion 713 of the cam member 71 enters the first tooth slot 721 of the gear member 72 and is stopped by the first tooth slot 721 to limit the rotation of the cam member 71 in the clockwise direction, and the protrusion 712 is located in the slot 511 of the first gear 51 and stopped on the tooth 512, so that the first gear 51 cannot rotate in the counterclockwise direction, and finally the first elastic member 40 cannot push the first clamping member 20 to move outwards, so as to position the first clamping member 20 at the first position and cooperate with the second clamping member 30 to clamp the mobile terminal together.

When the user presses the first clamping member 20 again, the first groove 221 of the first abutting block 22 and the second groove 321 of the second abutting block 32 are relied on to provide a space for the first clamping member 20 to move inward. The other latch 512 of the first gear 51 contacts the protrusion 712 of the cam member 71 to rotate the cam member 71 in the counterclockwise direction, such that the second protrusion 714 of the cam member 71 pushes the gear member 72 to rotate in the clockwise direction, thereby causing the first protrusion 713 of the cam member 71 to enter the second slot 722, as shown in fig. 21.

When the user releases the pushing of the first clamping member 20, the first elastic member 40 pushes the first clamping member 20 and the second clamping member 30 to move outward, and at this time, because the depth of the second tooth slot 722 is greater than the depth of the first tooth slot 721, the cam member 71 can rotate by a larger angle in the clockwise direction, so that the protrusion 712 is no longer blocked by the latch 512, and further the first gear 51 can rotate in the counterclockwise direction, and finally the first and second clamping members 20 and 30 are driven to pop out outward under the action of the first elastic member 40 through the first and second racks 212 and 312 engaged with the third gear 53, so as to be positioned at the second position, thereby terminating the clamping of the mobile terminal.

In summary, the utility model provides a mobile terminal clamping bracket, which provides the elastic force for the relative springing-off of the first clamping piece and the second clamping piece by arranging the first elastic piece in the shell, and simultaneously locks and unlocks the movable transmission assembly by the locking assembly, thereby realizing the locking and the contact locking at the specific position; the elastic force provided by the first elastic piece can relatively spring the first clamping piece and the second clamping piece open, so that the mobile terminal is more convenient to take down; the locking assembly consists of a cam piece and a gear piece, and a first tooth groove and a second tooth groove which are different in depth on the gear piece are matched with a first projection on the cam piece, so that the projection of the cam piece can be selectively interfered with the transmission assembly to realize locking or unlocking; the second lug on the cam piece selectively pushes the gear piece to enable the first lug to be switched from the first tooth groove to the second tooth groove, so that unlocking of the transmission assembly is achieved, and the transmission assembly can continuously bounce off the first clamping piece and the second clamping piece under the restoring force of the first elastic piece. When the mobile terminal clamping support is used, the first clamping piece is pressed once, and the first lug of the cam piece is matched with the first tooth groove of the gear piece, so that the convex part of the cam piece is positioned in the clamping groove of the transmission assembly and blocks the clamping teeth of the transmission assembly, and the purposes of clamping and locking the mobile terminal are achieved; the user presses the first clamping piece again, and the first convex block of the cam piece is matched with the second tooth groove of the gear piece, so that the convex part of the cam piece can rotate by a larger angle, the clamping teeth of the transmission assembly are not blocked any more, and the purposes of unlocking and taking down the mobile terminal are achieved; the operation of pressing down first holder in the outside-in with pressing from both sides tight mobile terminal compares and struts the operation of putting into mobile terminal again from inside to outside swift more, and can realize from the bullet auto-lock, gets to put the convenience, and the centre gripping is firm.
