Currently, the mobile phone holders on the market do not have a good fixing effect on the mobile phone. If the mobile phone holder vibrates violently, the mobile phone will detach from the holder, causing the mobile phone to fall and cause damage to the mobile phone. Summary of the invention

[0003] In order to solve the above technical problems, the utility model provides a locking structure for a mobile phone holder, which can enable the mobile phone holder to lock the mobile phone and prevent the mobile phone from falling off the mobile phone holder.

[0004] In order to solve the above problems, the utility model adopts the following technical solutions:

[0006] In this solution, the existing mobile phone holder is composed of a support plate and a support block. The frame is fixed to the back of the mobile phone holder so that the baffle is located above the mobile phone holder. The baffle is then stretched forward to a suitable position. After the mobile phone is placed on the mobile phone holder from the side, the elastic component pulls the corresponding connecting column backward, so that the two connecting columns drive the baffle to move toward the mobile phone until the baffle and the mobile phone are against each other. The baffle and the support block cooperate to clamp the mobile phone front and back, and then the connecting column is locked in the current position through the locking mechanism to prevent the baffle from driving the two connecting columns to move forward due to vibration and causing the mobile phone to detach from the support plate.

[0007] Preferably, the locking mechanism includes a friction plate and a connecting notch symmetrically arranged at the front of the connecting block, the connecting notch corresponding to the connecting column one by one, the connecting column passes through the corresponding connecting notch, a connecting hole along the left and right direction is provided in the connecting block, both ends of the connecting hole are respectively connected to the connecting notch on the corresponding side, a slide groove is provided on the rear side of the connecting hole, the connecting hole is used for the friction plate to pass through, a slider is provided at the position of the friction plate corresponding to the slide groove, the slider can slide left and right along the slide groove, the friction plate is symmetrically provided with locking holes that penetrate front and back, the locking holes are arranged in a left and right direction, the connecting column passes through the locking hole on the corresponding side, and the right side of the locking hole on the right side is provided with a first friction structure that fits with the outer wall of the connecting column on the corresponding side, the locking mechanism also includes a friction plate driving device for driving the friction plate to move left and right, and when the friction plate moves left and right, the connecting column can move in the corresponding locking hole.

[0008] When the friction plate driving device drives the friction plate to move to the left in the connecting hole, the sliding block moves to the left in the sliding groove, and the friction plate drives the first friction structure to move toward the connecting column on the corresponding side. During the movement of the friction plate, the locking hole does not contact the corresponding connecting column, and there is no friction between the connecting column and the friction plate until the first friction structure on the friction plate abuts against the connecting column on the corresponding side. At this time, the static friction force generated by the abutment between the first friction structure and the connecting column on the corresponding side can lock the locking column on the corresponding side, so that the connecting column on the corresponding side can no longer continue to move under external forces. When the friction plate driving device drives the friction plate to move to the right in the connecting hole, the sliding block moves to the right in the sliding groove, and the friction plate drives the first friction structure away from the connecting column on the corresponding side. The first friction structure loses the static friction force when it abuts against the connecting column on the corresponding side. At this time, the friction plate is unlocked from the two connecting columns, and the two connecting columns can move back and forth under external forces.

[0009] Preferably, the friction plate driving device includes a sliding block and a cam assembly arranged on the left side of the friction plate, the sliding block is located in the locking hole on the left side and can slide in the locking hole on the left side, the sliding block is arranged between the cam assembly and the connecting column on the left side, an arc-shaped friction surface of the connecting column is arranged on the right side of the sliding block, the arc-shaped friction surface of the connecting column matches the connecting column on the corresponding side, the cam assembly includes a handle and two cams, the two cams are symmetrically arranged on the front and rear sides of the friction plate, the cam is rotatably connected to the friction plate through a rotating shaft, the two cams are connected to the handle, and a reset assembly is provided in the slide groove, the reset assembly is used to move the first friction structure away from the connecting column on the corresponding side.

[0012] Preferably, an arc-shaped protrusion protruding to the right is provided on the left side of the locking hole on the left, and a curved surface is provided on the left side of the sliding block, and the arc-shaped protrusion matches the curved surface. When the cam assembly is in an unlocked state, the spring is in a normal state, the two cams do not contact the sliding block, and the locking hole does not contact the connecting column on the corresponding side. The sliding block can slide between the corresponding connecting column and the left side wall of the corresponding locking hole. When the cam assembly rotates counterclockwise to a locked state, the spring is in a stretched state, and the two cams and the sliding block are abutted against each other, driving the sliding block to abut against the connecting column on the corresponding side, and the first friction structure abuts against the connecting column on the corresponding side.

[0013] The handle is rotated backward counterclockwise so that the handle drives the two cams to rotate counterclockwise. When the two cams rotate, the protrusions of the cams begin to contact the curved surface of the sliding block, and the protrusions of the cams squeeze the curved surface to drive the sliding block to slide rightward in the locking hole until the arc-shaped friction surface of the connecting column on the right side of the sliding block contacts and abuts against the connecting column on the corresponding side. After the sliding block abuts against the corresponding connecting column, the two cams continue to rotate, thereby driving the friction plate to move leftward through the rotating shaft. When the cam rotates 90° counterclockwise, the first friction structure in the locking hole on the right side abuts against the connecting column on the corresponding side. At this time, the connecting column on the right side is subjected to the static friction force given by the first friction structure, and the connecting column on the left side is subjected to the static friction force given by the sliding block. Both connecting columns are locked, the baffle is in a locked state, and the spring is in a stretched state. The direction in which the cam assembly applies pressure to the sliding block is consistent with the direction in which the spring applies tension to the friction plate. When the mobile phone holder vibrates, the two connecting columns and the static friction force they are subjected to can lock the mobile phone on the mobile phone holder.

[0014] Preferably, the locking mechanism further comprises a friction protrusion symmetrically arranged on the right side of the friction plate, and an arc-shaped friction surface is arranged on the left side of the friction protrusion, and the arc-shaped friction surface is fitted with the connecting column on the corresponding side.

DETAILED DESCRIPTION

[0025] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0026] Embodiment: A locking structure for a mobile phone holder in this embodiment, such as Figures 1 to 5As shown, it includes a frame 1 and a baffle assembly 11 for connecting to the back of the mobile phone holder. The mobile phone holder is composed of a support plate 8 and a support block 9 arranged at the bottom of the support plate 8. The baffle assembly 11 includes a baffle 21 and a baffle connecting module 2. The baffle 21 is located on the front side of the frame 1. The baffle connecting module 2 includes a connecting block 22 arranged on the back of the frame 1. The front end surface of the connecting block 22 is symmetrically provided with guide holes 23. The guide holes 23 are arranged in a front-to-back direction. A connecting column 24 is slidably connected in the guide hole 23. An elastic component is arranged between the connecting column 24 and the rear end surface of the guide hole 23. The front part of the connecting column 24 extends out of the guide hole 23 and is fixedly connected to the lower part of the baffle 21.

[0027] The locking mechanism 3 includes a friction plate 31 and a connecting notch 32 symmetrically arranged at the front of the connecting block 22.

A connecting hole 33 along the left-right direction is provided in the connecting block 22. Both ends of the connecting hole 33 are respectively connected to the connecting notch 32 on the corresponding side. A slide groove is provided on the rear side of the connecting hole 33. A slider 34 is provided at the position of the friction plate 31 corresponding to the slide groove. The slider 34 can slide left and right along the slide groove. The friction plate 31 is symmetrically provided with locking holes 35 passing through the front and back. The locking holes 35 are arranged in a left-right direction. The connecting column 24 passes through the locking hole 35 on the corresponding side. The right side of the locking hole 35 on the right side is provided with a first friction structure 36 that fits with the outer wall of the connecting column 24 on the corresponding side. The locking mechanism 3 also includes a friction plate driving device 4 for driving the friction plate 31 to move left and right.

[0028] The friction plate driving device 4 includes a sliding block 41 and a cam assembly 42 arranged on the left side of the friction plate 31. The sliding block 41 is located in the locking hole 35 on the left and can slide in the locking hole 35 on the left. The sliding block 41 is arranged between the cam assembly 42 and the connecting column 24 on the left. An arc-shaped friction surface of the connecting column is arranged on the right side of the sliding block 41, and the arc-shaped friction surface of the connecting column matches the connecting column on the corresponding side. The cam assembly includes a handle and two cams. The two cams are symmetrically arranged on the front and rear sides of the friction plate 31. The cams are rotatably connected to the friction plate 31 through a rotating shaft. The two cams are both connected to the handle, and a reset assembly 5 is provided in the slide groove.

[0029] The reset assembly 5 includes a spring, both ends of which are fixedly connected to the right side wall of the slider and the slide groove respectively. The reset assembly 5 also includes a spring stopper 51, which is fixedly connected to the friction plate 31. The spring stopper 51 is located above the spring, and the spring stopper 51, the slider 34 and the slide groove form a spring groove.

[0030] An arc-shaped protrusion 351 protruding to the right is provided on the left side of the locking hole 35 on the left side, and a curved surface is provided on the left side of the sliding block 41 , and the arc-shaped protrusion 351 matches the curved surface.

[0031] The locking mechanism 3 also includes a friction protrusion 6 symmetrically arranged on the right side of the friction plate 31, and an arc-shaped friction surface 61 is arranged on the left side of the friction protrusion 6, and the arc-shaped friction surface 61 is in contact with the connecting column 24 on the corresponding side. The rear side of the baffle 21 is provided with an anti-collision block 7 and a bracket buffer block 73 from top to bottom. The bottom surface of the anti-collision block 7 is a friction surface, and the bracket buffer block 73 is used to buffer the mobile phone bracket and the baffle. The upper part of the rear side of the baffle 21 is symmetrically provided with a limiting protrusion 71, and the front side of the baffle 21 is provided with a lifting notch 72. The front side of the connecting notch 32 is a first limiting surface, and the rear side of the connecting notch 32 is a second limiting surface. The first limiting surface and the second limiting surface are used to prevent the sliding block 41 from falling out of the connecting notch 32.

[0032] In this solution, the baffle is stretched forward to a suitable position by pulling the notch, and then the mobile phone is placed on the mobile phone holder and the elastic component pulls the corresponding connecting column backward, so that the two connecting columns drive the baffle to move toward the mobile phone until the baffle is against the top of the mobile phone, and the anti-collision block provided on the rear side of the baffle is against the top of the mobile phone. The bottom surface of the anti-collision block is a friction surface, which can increase the friction force of the anti-collision block on the mobile phone. After the baffle is against the mobile phone, the handle is rotated backward counterclockwise so that the handle drives the two cams to rotate counterclockwise. When the two cams rotate, the protrusion of the cam begins to contact the curved surface of the sliding block, and the protrusion of the cam is squeezed with the curved surface to drive the sliding block to slide rightward in the locking hole until the arc-shaped friction surface of the connecting column on the right side of the sliding block contacts and abuts against the connecting column on the corresponding side. After the sliding block abuts against the corresponding connecting column, the two cams are continued to be rotated by the handle, thereby rotating The shaft drives the friction plate to move to the left. When the friction plate moves to the left in the connecting hole, the slider moves to the left in the slide groove, and the friction plate drives the first friction structure to move toward the connecting column on the corresponding side. During the movement of the friction plate, the locking hole does not contact the corresponding connecting column, and there is no friction between the connecting column and the friction plate. When the cam rotates 90° counterclockwise, the first friction structure in the locking hole abuts against the connecting column on the corresponding side. At this time, the connecting column on the right side abuts against the first friction structure on the corresponding side. The static friction force generated by the abutment of the first friction structure on the right side and the connecting column on the right side can lock the locking column on the right side, so that the connecting column on the right side can no longer continue to move under external force, and the connecting column on the left side is subjected to the static friction force given by the sliding block. Both connecting columns are locked, the baffle is in a locked state, and the spring is in a stretched state.

[0033] When the mobile phone needs to be removed from the mobile phone holder, the handle is rotated clockwise so that the protruding part of the handle no longer contacts the curved surface of the sliding block. The spring drives the friction plate to slide to the right, and the first friction structure in the locking hole no longer abuts against the connecting column on the corresponding side. The sliding block can slide in the corresponding locking hole until the spring returns to a normal state.

[0034] In order to connect the mobile phone holder to the mobile phone, limiting protrusions are symmetrically arranged on the upper rear side of the baffle. When the mobile phone is squeezed by the baffle, the two limiting protrusions can be located above the top of the mobile phone to prevent the mobile phone from tipping over and falling off the mobile phone holder.

[0035] The direction in which the cam assembly applies pressure to the sliding block is consistent with the direction in which the spring applies tension to the friction plate. When the mobile phone holder vibrates, the static friction force exerted on the two connecting columns and each of them can lock the mobile phone on the mobile phone holder.

[0036] When the cam assembly is in an unlocked state, the first friction structure does not contact the connecting column on the corresponding side and there is a small gap, and the sliding block does not contact the connecting column on the corresponding side. When the cam assembly is switched from an unlocked state to a locked state, the first friction structure moves toward the connecting column on the corresponding side to eliminate the gap between the two and offset each other, and the sliding block is pushed by the two cams to move toward the connecting column on the corresponding side and offset each other.
