As shown in FIGS. 1 to 4, the mobile terminal bracket includes a base body 20, a base 10, a first clamping portion 30, a second clamping portion 40, a support portion 50, and a linkage assembly 60. The base 10 is used to mount the mobile terminal bracket on a fixture. The base 20 is movably mounted on the base 10. The support portion 50 is fixed to the base body 20 for carrying the mobile terminal. The first clamping portion 30 and the second clamping portion 40 are movably mounted on the base body 20, and the linkage assembly 60 is coupled to the base 10, the base body 20, the first clamping portion 30, and the second clamping portion 40, respectively. When the mobile terminal is supported on the support portion 50, the base body 20 moves relative to the base 10 to drive the linkage assembly 60, thereby causing the first clamping portion 30 and the second clamping portion 40 to move toward each other to clamp the mobile terminal. In the present application, the mobile terminal may be a tablet-shaped smart device, including but not limited to a mobile phone, a tablet computer, a personal digital assistant, and the like.

In the present embodiment, the susceptor 10 has a substantially flat shape. The base 10 can be fixed to other objects according to the application. For example, in the office, the base 10 can be fixed on a desk or a wall by bonding, supporting, or the like. In the use of the interior of the car, it can be connected to the position of the air conditioning vent of the car through a clamp 70, so that the entire bracket can be fixed.

The base body 20 is movably coupled to the base 10 relative to the base 10, preferably movably coupled to the base 10 in the direction of gravity. For example, the base body 20 can be connected to the base 10 through a chute-slider structure. However, those skilled in the art can also select other conventional structures to realize the mobile connection between the base 20 and the base 10, which is not limited in the present invention. In the present embodiment, the base body 20 includes a rear cover 21 and a face shell 28. The rear cover 21 is generally a rectangular parallelepiped having an open side, and a side opposite to the open face is movably coupled to the base 10. The face shell 28 is fastened to the open face of the back cover 21 such that the face shell 28 and the back cover 21 constitute an inner hollow casing. However, in some embodiments, the face shell 28 can also be omitted.

The support portion 50 is disposed at the bottom of the base body 20, and may be disposed at the bottom of the back cover 21 or at the bottom of the cover shell 28, and may be integrally formed, fixedly connected, or Detachably connected, rotatably or movably connected. The support portion 50 protrudes from a side of the base body 20 facing the mobile terminal (ie, a side facing away from the base 10). In some embodiments, if the face shell 28 is omitted, the support portion 50 can protrude from the side of the back cover 21 facing away from the base 10. In other embodiments, after the face shell 28 is fastened to the back cover 21, the support portion 50 protrudes from the side of the face shell 28 facing the mobile terminal (ie, the side facing away from the base 10), and the user places the mobile terminal along the face shell 28. The side is placed on the support portion 50. In the present embodiment, the number of the support portions 50 may be one or two or more. In the case where the number of the support portions 50 is one, the support portion 50 is preferably located at the center of the bottom of the base body 20. In the case where the number of the support portions 50 is two, it is preferable that the midpoints of the two support portions 50 are located substantially at the center of the bottom portion of the base body 20. Thus, the support portion 50 can securely lift the mobile terminal when the mobile terminal is placed on the support portion 50. In some embodiments, the support portion 50 has a hook shape that is perpendicular to or inclined to the base body 20, or a rod-like structure. In the embodiment in which the support portion 50 has a hook shape, the bottom of the mobile terminal can be placed at the hook-shaped recess, so that the direction in which the mobile terminal is detached from the base 20 can be prevented, and the fastening is better.

The first clamping portion 30 is movably coupled to the base body 20 in a first sliding direction and protrudes from a side of the base body 20 that faces the mobile terminal. The second clamping portion 40 is movably coupled to the base body 20 in a second sliding direction and protrudes from a side of the base body 20 that faces the mobile terminal. The first sliding direction and the second sliding direction are located on the same plane and are inclined to each other, and the distance between the first sliding direction and the second sliding direction is gradually reduced in a direction close to the support portion 50, so that the first clamping portion 30 and the first The two holding portions 40 approach each other when moving in the direction of the support portion 50, and are apart from each other when moving away from the support portion 50. In this embodiment, the bracket may further include a first clamping arm 31 and a second clamping arm 41. The first clamping portion 30 is disposed at an end of the first clamping arm 31, and the second The clamping portion 40 is provided at an end of the second clamping arm 41. The first clamping arm 31 is movably coupled to the rear cover 21 in the first sliding direction, and the second clamping arm 41 is movably coupled to the rear cover 21 in the second sliding direction. The first clamping portion 30 and the second clamping portion when the first clamping arm 31 and the second clamping arm 41 move in a direction in which the first sliding direction and the second sliding direction are respectively close to the support portion 50 40 is also moved in the direction of the support portion 50, and the first clamping portion 30 and the second clamping portion 40 are close to each other until the mobile terminal is clamped with the support portion 50. The first clamping arm 31 and the second clamping arm 41 can be movably coupled to the rear cover 21 by various means. As an example, the rear cover 21 is provided with a first slot extending in the first sliding direction. And a second slot body 23 extending along the second sliding direction, the first clamping arm 31 is provided with a plurality of pins embedded in the first slot body 22, and the second clamping arm 41 is provided There are a plurality of pins embedded in the second groove body 23. Thus, the first clamping arm 31 is movably coupled to the rear cover 21 through the first slot 22 and the pin engaged with the first slot 22, and the second clamping arm 41 passes through the second slot 23 and the second The pin of the groove body 23 is movably coupled to the rear cover 21. However, the first clamping arm 31 and the second clamping arm 32 can still be movably coupled to the rear cover 21 by other means, such as the three implementations shown in Figures 9-11.

Wherein, the first trough body 22 and the second trough body 23 are oppositely inclined, and the distance between the ends of the first trough body 22 and the second trough body 23 near the support portion 50 is smaller than the distance between the first trough body 22 and the second trough body 23; The distance between the ends of the support portion 50. In this way, the first clamping arm 31 can be inserted into the first groove body 22 through the pin to slide along the length direction of the first groove body 22, and the second clamping arm 41 can be inserted into the second groove body 23 through the pin. The inner side slides along the longitudinal direction of the second groove body 23.

The linkage assembly 60 is configured to utilize the relative movement between the base 20 and the base 10 to move the first clamping portion 30 and the second clamping portion 40 to clamp the mobile terminal. The linkage assembly 60 is coupled to the first clamping portion 30, the second clamping portion 40, the base 20, and the base 10, respectively. In this embodiment, the linkage assembly 60 is located in a cavity between the face shell 28 and the back cover 21. When the mobile terminal is placed on the support portion 50, the base body 20 moves relative to the base 10 to drive the first clamping portion 30 and the second clamping portion 40 respectively along the linkage assembly 60. The first sliding direction and the second sliding direction are moved such that the first clamping portion 30 and the second clamping portion 40 move respectively near the support portion 50 and the first clamping portion 30 and the second portion The clamping portions 40 are close to each other until the mobile terminal is held together with the support portion 50. In some embodiments, the linkage assembly 60 may further include one or more elastic members for driving the first clamping portion 30 and the second clamping portion 40 away from the movable terminal after the mobile terminal is disengaged from the bracket. The support portion 50 moves. A person skilled in the art can reasonably set the strength and/or the amount of compression of the elastic member such that the first clamping portion 30 and the second clamping portion 40 return to the preset position after the mobile terminal is disengaged from the bracket.

In this embodiment, the base 10 is provided with a base pin 11 , and the linkage assembly 60 includes a first linkage 61 and a second linkage 62 . The first linkage 61 is provided with a first connection point 611, a second connection point 612, and a first arcuate groove 613. The first linkage 61 is rotatably coupled to the first clamping arm 31 at the first connection point 611, and rotatably coupled to the rear cover 21 at the second connection point 612. The second linkage 62 is provided with a third connection point 621, a fourth connection point 622 and a second arcuate slot 623. The second linkage 62 is rotatably coupled to the second clamping point at the third connection point 621. The arm 41 is rotatably coupled to the rear cover 21 at the fourth connection point 622. In some embodiments, the second connection point 612 and the fourth connection point 622 may coincide such that the first linkage 61 and the second linkage 62 are overlappedly coupled to the same position of the rear cover 21. Further, the base pin 11 passes through the rear cover 21 and is simultaneously embedded in the first curved groove 613 and the second curved groove 623. Obviously, in other embodiments, the second connection point 612 and the fourth connection point 622 may not overlap, and the base pin 11 may also be two or more, respectively embedded in the first curved slot 613 and the second. In the arc groove 623. In the embodiment, the first linkage 61 and the second linkage 62 are pivotally connected to the rear cover 21 via a rotating shaft 27, respectively. As shown in FIG. 3, the rotating shaft 27 protrudes from a side of the rear cover 21 facing the first linkage 61 and the second linkage 62, and passes through a second connection point of the first linkage 61. 612 and a fourth connection point 622 of the second linkage 62. The elastic member may be a torsion spring sleeved on the rotating shaft 27, one end of the torsion spring is connected to the first linkage member 61, and the other end is connected to the second linkage member 62. However, the elastic member may also be other implementations, for example, may be connected between the rear cover 21 (for example, connected to the rotating shaft 27 of the rear cover 21) and the first clamping arm 31 and/or the second clamping arm 41. The spring or the like may be, for example, a spring connected between the rear cover 21 and the base pin 11. In order to more clearly explain the connection relationship between the components of the present embodiment, the process of fixing the mobile terminal by the mobile terminal bracket provided by the present embodiment is described in detail below.

First, the mobile terminal is placed on the support portion 50, and the support portion 50 drives the base body 20 to move downward relative to the base 10 under the gravity of the mobile terminal. During the movement, since the support portion 50 is fixedly coupled to the base body 20, there is no relative movement between the support portion 50 and the base body 20, and the mobile terminal follows the support portion 50 and the base body 20 to move downward with respect to the base 10 under the action of gravity, that is, There is no relative movement and relative friction between the mobile terminal and the base 20.

Then, the first linkage member 61 and the second linkage member 62 move the base pin 11 along the first arcuate groove 613 and the second arcuate groove 623 as the base 20 moves downward, so that the first linkage 61 can be driven. And the second linkage 62 rotates. When the first linkage member 61 and the second linkage member 62 rotate, the elastic member can also be elastically deformed.

Finally, since the first linkage 61 and the second linkage 62 are rotatably coupled to the first clamping arm 31 and the second clamping arm 41, respectively, the first linkage 61 can drive the first of the first clamping arms 31. The clamping portion 30 moves closer to the supporting portion 50 in the first sliding direction, and the second linkage 62 can drive the second clamping portion 40 of the second clamping arm 41 to move closer to the supporting portion 50 in the second sliding direction. During the movement of the first clamping portion 30 and the second clamping portion 40 near the support portion 50, the first clamping portion 30 and the second clamping portion 40 are also close to each other until the mobile terminal is clamped together with the support portion 50. After the mobile terminal is disengaged from the bracket, the first clamping portion 30 and the second clamping portion 40 are respectively moved away from the support portion 50 by the restoring force of the elastic member until returning to the predetermined position.

The mobile terminal bracket provided by the present invention places the mobile terminal on the support portion 50, and the base body 20 moves relative to the base 10 to fix and fix the mobile terminal. During the installation process, the mobile terminal does not need to be moved relative to the bracket, thereby preventing the mobile terminal from being installed. The surface is scratched by the mobile terminal during the stand. The bracket provided by the embodiment is particularly suitable for the use of the mobile phone in the vehicle, and can prevent the mobile terminal from sliding against the bracket to scratch the surface of the mobile terminal while the vehicle is running.

Fig. 5A is a schematic view showing the position of the mobile terminal in a laterally placed and longitudinal manner. As shown in FIG. 5A, when the same mobile terminal is placed in the lateral direction and the longitudinal direction, the overlapping areas of the same mobile terminal are substantially square (the side length is the same mobile terminal). FIG. 5B is a schematic diagram of the active trajectory of the first clamping portion and the second clamping portion of the mobile terminal bracket according to the first embodiment of the present invention. As shown in FIG. 5B, by arranging the first sliding direction and the second sliding direction reasonably, the first clamping arm 31 and the second clamping arm 41 are clamped to the mobile terminal with the support portion 50, the first clamping portion 30 The nip point of the second clamping portion 40 is located at the left and right corners of the square. For most mobile phones used on the market, the aspect ratio is about 2:1, so the distance between the nip points of the first clamping portion 30 and the second clamping portion 40 is about the width of the mobile terminal. It is also about half of the long side, that is, the nip point is located at the midpoint of the long side when placed in the longitudinal direction, and the lateral movement distance (for example, X) of the first nip portion 30 and the second nip portion 40 is the longitudinal movement distance ( For example, half of 2X). FIG. 5C is a schematic diagram of the mobile terminal bracket longitudinal clamping mobile terminal 28 according to the first embodiment of the present invention. FIG. 5D is a schematic diagram of the mobile terminal bracket lateral clamping mobile terminal 28 according to the first embodiment of the present invention. The mobile terminal bracket provided by the present embodiment is suitable for the mobile terminal 28 of various sizes to be clamped in a lateral or longitudinal manner. As shown in FIG. 5C, when the mobile terminal holder holds the mobile terminal 28 in the longitudinal direction, the nip points of the first clamping portion 30 and the second clamping portion 40 are located on both sides of the mobile terminal 28 when the mobile terminal 28 is longitudinally clamped. At the center of the long side. As shown in FIG. 5D, when the mobile terminal holder grips the mobile terminal 28 laterally, the midpoints of the first clamping portion 30 and the second clamping portion 40 are located at the center of the long side of the mobile terminal 28. In theory, the center of gravity of the mobile terminal 28 is also generally located in the center of the mobile phone, so that the mobile terminal can be firmly fixed, and is particularly suitable for the use of the mobile terminal 28 in the car, thereby preventing the situation of the scorpion tail when the vehicle is bumping. .

The mobile terminal bracket provided by the present embodiment moves the base body 20 relative to the base 10 under the action of the weight of the mobile terminal, and pulls the first clamping portion 30 and the second clamping portion 40 toward the support portion 50 and close to each other through the linkage assembly 60, respectively. The direction is moved until the mobile terminal is clamped together with the support portion 50 such that the nip points of the first clamping portion 30 and the second clamping portion 40 are located at the corners of the overlapping region of the mobile terminal when installed in the lateral direction and the longitudinal direction, such that the mobile terminal In the case of lateral or longitudinal mounting, the midpoints of the clamping positions of the first clamping portion 30 and the second clamping portion 40 are generally located at the gravity action line of the mobile terminal, so that the weight of the mobile terminal can be used to achieve horizontal or vertical fixation.
