[0002] With the improvement of people's living conditions, household cars have become a necessary means of transportation for every family. However, with the development of the city, the roads have become increasingly complex. For local or foreign people who are not familiar with the roads, mobile phone navigation has become a good helper for them to successfully reach their destinations. If they only listen to the voice of the navigation, they are likely to miss a turn inadvertently. However, if they frequently take out their mobile phones to look at the map, it is easy to be dangerous. The in-vehicle mobile phone bracket successfully solves this problem. Placing the mobile phone on the bracket can realize listening to the voice and looking at the map at the same time, improving the safety factor of driving.

[0003] Currently, the common mobile phone brackets are divided into two types: magnetic adsorption type and clip type.

[0029] Among them, the housing 1 is formed by docking and combining the front and rear shells, and both left and right sides inside the rear shell of the housing 1 are provided with sliding grooves 11. And the two sliding grooves 11 are respectively slidably connected and matched with the pivot centers 212 provided on one side of the lower ends of the left connecting rod 28 and the right connecting rod 29. And, both sliding grooves 11 are arranged in a transverse groove shape. In this way, it can be ensured that the left connecting rod 28 and the right connecting rod 29 can slide along the direction of the sliding groove 11.

[0030] Please refer to Figure 3-9The clamp arm assembly 2 in this embodiment includes a left clamp arm 21 installed horizontally on the left side of the shell 1, a right clamp arm 22 installed horizontally on the right side of the shell 1, and a bottom support arm 23 installed vertically at the lower end of the shell 1. Connecting grooves 24 are respectively provided inside one side of the left clamp arm 21 and the right clamp arm 22, and the connecting grooves 24 are provided in a vertical groove shape as a whole, so as to cooperate with the connecting grooves 24 on both sides, so that when the left connecting rod 28 or the right connecting rod 29 moves the left clamp arm 21 or the right clamp arm 22 correspondingly, it can slide along the connecting grooves 24 on both sides. A docking hole 25 for positioning and docking is provided in the middle of the bottom support arm 23, and a first magnetic attraction member can be provided inside the docking hole 25, and a second magnetic attraction member can be provided on the shell 1, so as to facilitate the connection between the two sides of the left clamp arm 21 and the right clamp arm 22. Here, the product noise is reduced by magnetically cooperating with the first magnetic attraction member and the second magnetic attraction member. The bottom support arm 23 is composed of a bottom support portion 27 and a fixing portion 26, and the fixing portion 26 is installed at the upper end of the bottom support portion 27. The fixing portion 26 includes a fixing seat 261 installed at the upper end of the bottom support arm 23, and a docking terminal 262 integrally installed in the middle of the lower end of the fixing seat 261. The fixing seat 261 can be buckled and combined with the docking hole 25 provided in the middle of the bottom support arm 23 through the docking terminal 262 provided in the middle of the lower end. The hinge shafts 263 for hinged cooperation are integrally installed on both sides of the upper end of the fixing seat 261, and the reset components 3 for elastic reset transmission are correspondingly installed at the outer ends of the hinge shafts 263 on both sides.

[0031] Specifically, hinge shafts 263 are connected to the left and right sides of the upper end of the fixed seat 261, and the hinge shafts 263 on both sides are respectively hingedly combined with the left connecting rod 28 and the right connecting rod 29, thereby ensuring that the left connecting rod 28 and the right connecting rod 29 can achieve a stable hinged combination with the bottom support arm 23; the left clamping arm 21 and the right clamping arm 22 can both be slidably connected and matched with the first connecting end 210 provided inside the left connecting rod 28 or the right connecting rod 29 through the connecting groove 24 provided inside, so that when the left connecting rod 28 or the right connecting rod 29 moves the left clamping arm 21 and the right clamping arm 22, they can cooperate with the connecting groove 24 to achieve stable rotation and swinging activities.

The integrated spring can ensure uniform force, and the two spiral centers 32 are smoother when installing the springs.

[0033] Specifically, the spring push rods 33 provided on both sides of the spring are respectively moved into the limit grooves 213 opened inside the left connecting rod 28 and the right connecting rod 29, so that the spring can cooperate with its own elastic force to realize the reset transmission cooperation of the left connecting rod 28 and the right connecting rod 29; an opening is opened at the end of the hinge shaft 263, and a countersunk buckle is provided at the end of the hinge shaft 263 to ensure that the hinge shaft 263 cooperates with the opening and the countersunk buckle to be quickly assembled with the left connecting rod 28 or the right connecting rod 29.

[0034] Specifically, the clamp arm assembly 2 also includes a left connecting rod 28 installed on the left side of the shell 1, and a right connecting rod 29 installed on the right side of the shell 1, and the left connecting rod 28 and the right connecting rod 29 are symmetrically arranged on the left and right sides, and the first connecting ends 210 are respectively arranged on the upper ends of the left connecting rod 28 and the right connecting rod 29, and the left connecting rod 28 and the right connecting rod 29 are movably connected to the left clamp arm 21 and the right clamp arm 22 through the first connecting ends 210 arranged at the upper ends, and the second connecting ends 211 are respectively arranged on the lower ends of the left connecting rod 28 and the right connecting rod 29, and the left connecting rod 28 and the right connecting rod 29 are respectively hinged to the upper end of the bottom support arm 23 through the second connecting ends 211 arranged at the upper ends. The left connecting rod 28 and the right connecting rod 29 are connected to the pivot center 212 on the lower end side of the left connecting rod 28 and the right connecting rod 29, and the left connecting rod 28 and the right connecting rod 29 are movably connected to the slide grooves 11 on both sides of the shell 1 through the pivot center 212 on the lower end side. In this way, when the bottom support arm 23 moves up and down, it can drive the left connecting rod 28 and the right connecting rod 29 to rotate and swing around the corresponding pivot center 212, and then, in conjunction with the first connecting end 210, the left clamping arm 21 and the right clamping arm 22 are correspondingly moved to telescope and move, thereby achieving a stable clamping fit, and the limiting grooves 213 on one side of the left connecting rod 28 and the right connecting rod 29 are respectively arranged.

[0035] Specifically, the pivot center 212 arranged inside the left connecting rod 28 is located on the outside between the first connecting end 210 and the second connecting end 211 on the outer surface of the left connecting rod 28, and the so-called outside refers to the direction away from the symmetry plane of the mobile phone gravity bracket, and the right connecting rod 29 arranged inside the right connecting rod 29 is located between the first connecting end 210 and the second connecting end 211 on the outer surface of the right connecting rod 29, and the pivot centers 212 on both sides are located on the left or right side of the line connecting the first connecting end 210 and the second connecting end 211. The pivot center 212 is arranged on the outside between the first connecting end 210 and the second connecting end 211, which can reduce the friction between the left connecting rod 28 and the right connecting rod 42 during movement, and the movement of the clamping arm assembly 2 is smoother; the docking slide groove 21 can constrain the clamping arm assembly 2, and can avoid self-locking during the movement of the movable clamping arm assembly 2, so that the movement of the clamping arm assembly 2 is smoother.

[0036] Here’s how it works:

[0037] When using this mobile phone holder, the mobile phone can be placed on the upper end of the bottom support arm 23 provided inside the clamping arm assembly 2. The bottom support arm 23 is subjected to the weight of the mobile phone, realizing automatic downward movement. As the bottom support arm 23 moves downward, the fixing part 26 installed on the upper end of the bottom support arm 23 will cooperate with the hinge shafts 263 provided on both sides of the upper end to realize the pulling of the left connecting rod 28 and the right connecting rod 29 at the outer ends. The left connecting rod 28 and the right connecting rod 29 can be slidably docked with the two-side sliding grooves 11 inside the housing 1 through the pivot center 212 and slidably docked with the connecting grooves 24 provided on one side inside the left clamping arm 21 and the right clamping arm 22 through the first connection end 210, so that the left connecting rod 28 and the right connecting rod 29 rotate and swing relatively, realizing the contraction drive of the left clamping arm 21 and the right clamping arm 22 provided on both sides of the housing 1. In this way, the contracted left clamping arm 21 and the right clamping arm 22 can clamp both sides of the mobile phone and cooperate with the bottom support arm 23 to realize the stable clamping and placement of the whole mobile phone;

[0038] Secondly, when the bottom support arm 23 moves downward to drive the left connecting rod 28 and the right connecting rod 29 to rotate and swing relatively, the compression of the reset parts 3 connected to the outer ends of the two hinge shafts 263 can be realized, providing elastic preparation activities for subsequent unlocking and resetting;

[0039] When the mobile phone needs to be taken out, just directly take out the mobile phone upward to relieve the gravity extrusion effect of the bottom support arm 23. In this way, the reset parts 3 installed at the outer ends of the two hinge shafts 263 will rebound and reset, realizing the reverse swing of the left connecting rod 28 and the right connecting rod 29. Under the reverse swing of the left connecting rod 28 and the right connecting rod 29, the fixing seat 261 hinged to the left connecting rod 28 and the right connecting rod 29 through the two hinge shafts 263 will drive the overall upward movement and reset of the bottom support arm 23. In this way, convenient clamping unlocking and reset activities are realized, thus achieving the advantages of single-handed operation clamping and placement of the mobile phone and improving the convenience of using the support;

[0040] Among them, when the left connecting rod 28 and the right connecting rod 29 are docked with the hinge shafts 263 provided on both sides of the upper end of the fixing seat 261, elastic snap-fitting can be realized through the openings and buckles respectively provided at the end and the end of the hinge shaft 263, realizing rapid assembly and combination and strengthening the rapid assembly of the whole support.

[0041] The above are only the preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
