In this way a flexible adjustment of the angle of the mobile terminal support and the fixing means connected to the first connection structure 41 and the second connection structure 42 is achieved. The universal ball connecting structure herein includes both a universal ball and a structure for engaging the universal ball.

Two specific embodiments of a gimbaled ball connection are shown. In this embodiment, the first connecting structure 41 specifically includes a stud fixedly connected to the first joint portion 10 through the first connecting portion 14, and a nut sleeved on the stud, the nut being screwed with the stud. The stud is of a hollow structure, a longitudinal notch is formed in the side wall of the stud, and an accommodating space for the universal ball to be inserted and connected is formed in the stud. The universal ball is locked and engaged by the nut, and the universal ball is kept to rotate freely in the universal ball. The second connecting structure 42 is a universal ball fixedly connected to the second joint part 20 by the second connecting part 24.

It will be understood by those skilled in the art that the illustrations are merely exemplary, and that in practice the configuration of the first connection structure 41 and the second connection structure 42 may be adjusted or interchanged as desired, i.e., the first connection structure 41 is a gimbaled ball and the second connection structure 42 is a structure for engaging a gimbaled ball; both may also be gimbaled balls, or both may be structures for engaging a gimbaled ball.

In this manner, the form of the first and second connecting structures 41 and 42 may be selected according to the manner of attachment of the securing device to be attached to the mobile terminal support. For example, when the fixing device and the mobile terminal bracket to be connected both have a universal ball, the first and second connecting structures 41 and 42 in the vehicle-mounted connecting device provided by the embodiment of the present invention are both structures for engaging the universal ball; conversely, when the mobile terminal support and the fixing device to be connected are provided with the gimbaled ball engaging structure, the first and second connecting structures 41 and 42 are gimbaled balls; or when the fixture with the gimballed ball is to be connected to a mobile terminal support with a gimballed joint structure, or vice versa, the first and second connecting structures 41 and 42 may be one gimballed ball and the other gimballed joint structure.

In the particular embodiment shown in the figures, the mounting axes of the first connecting structure 41 and the second connecting structure 42 are parallel and the mounting direction is opposite. In this way, the mounting axis or support axis between the first connecting structure 41 and the second connecting structure 42 is always kept parallel during the rotation of the first connecting arm 31 and the second connecting arm 32. The stability of on-vehicle connecting device has been promoted.

Generally, the mounting axis is orthogonal to the mounting interface, coinciding with the direction of support of the connection structures 41 and 42.

In the embodiment shown in the drawings, the first connecting structure 41 is a stud and a nut sleeved on the stud, and the installation axis refers to a central axis of the stud and is orthogonal to the installation contact surface of the stud and the first joint 10. For another example, in the embodiment shown in the figures, the second connecting structure 42 is a universal ball, and the mounting axis refers to a central axis of a connecting column fixedly connecting the second joint 22 and the universal ball, which is perpendicular to the disc-shaped plane of the second connecting portion 24 and is consistent with the supporting direction of the universal ball.

The first connecting structure 41 and the second connecting structure 42 are installed in opposite directions, that is, they are located on opposite sides of the first joint 10 and the second joint 20. The installation directions of the first connecting structure 41 and the second connecting structure 42 are opposite, the connecting arms can rotate to a large rotation angle parallel or perpendicular to the installation axis, and the adjustment range of the height and the angle is further enlarged.

It will be understood by those skilled in the art that the mounting directions of the first connecting structure 41 and the second connecting structure 42 are not limited thereto, and may be the same, or located on two opposite sides of the first joint 10 and the second joint 20, or at other angles to adapt to other positions fixed in the vehicle.

Please continue to refer to fig. 2 and 3. In the particular embodiment shown in the figures, the first connecting arm 31 and the second connecting arm 32 are pivotally connected to the first joint part 10 and the second joint part 20. Specifically, one end of the first connecting arm 31 is rotatably connected to the first joint 10 by a first pin 11, and the other end is rotatably connected to the second joint 20 by a second pin 21; one end of the second joint arm 32 is rotatably connected to the first joint 10 by a third pin 12, and the other end is rotatably connected to the second joint 20 by a fourth pin 22. The first joint part 10, the second joint part 20, the first connecting arm 31, and the second connecting arm 32 are provided with pin holes at corresponding positions, into which the first pin 11, the second pin 21, the third pin 12, and the fourth pin 22 are inserted.

In the embodiment shown in the drawings, the first joint part 10 is provided with first pin holes 131 and 132, and the second joint part 20 is provided with second pin holes 231 and 232. The first connecting arm 31 and the second connecting arm 32 are provided with third pin holes 331 and 332 at one end for connecting the first joint portion 10, and fourth pin holes 341 and 342 at one end for connecting the second joint portion 20. The first pin 11 is inserted into the first pin hole 131 of the first joint 10 and the third pin hole 331 of the first connecting arm 31, so that one end of the first connecting arm 31 is rotatably connected to the first joint 10. The second pin 21 is inserted into the second pin hole 231 of the second joint part 20 and the fourth pin hole 341 of the first link arm 31, and the other end of the first link arm 31 is rotatably connected to the second joint part 20. The third pin 12 is inserted into the first pin hole 132 of the first joint 10 and the third pin hole 332 of the second link arm 32, so that one end of the second link arm 32 is rotatably connected to the first joint 10. The fourth pin shaft 22 is inserted into the second pin hole 232 of the second joint part 20 and the fourth pin hole 342 of the second link arm 32, and the other end of the second link arm 32 is rotatably connected to the second joint part 20.

It should be understood by those skilled in the art that the above is only an example of the vehicle-mounted connecting device according to the embodiment of the present invention, and other rotational connecting manners (such as hinging) between the connecting arms 31 and 32 and the joints 10 and 20 can be adopted; alternatively, the first connecting arm 31 may be integrated with the first pin 11 and/or the second pin 21, and the second connecting arm 32 may be integrated with the third pin 12 and/or the fourth pin 22; alternatively, the first joint part 10 may be integrated with the first pin 11 and/or the third pin 12, and the second joint part 20 may be integrated with the second pin 21 and/or the fourth pin 22; and so on.

In the vehicle-mounted connecting device according to the embodiment of the present invention, the distance between the axis of the first pin 11 and the axis of the third pin 12 is a first distance, the distance between the axis of the third pin 21 and the axis of the fourth pin 22 is a second distance, and the first distance is equal to the second distance; moreover, a connection line between the axis of the first pin 11 and the axis of the third pin 12 is a first connection line, a connection line between the axis of the second pin 21 and the axis of the fourth pin 22 is a second connection line, and the first connection line is parallel to the second connection line.

The four pivot pins 11, 12, 21, 22 coincide with the axes of rotation of the two connecting arms 31, 32 on the two joints 10, 20. In this embodiment, the two articulations 11 and 12 therefore always remain parallel to one another also during the rotation of the connecting arms 31, 32. Such a structure helps to maintain the fixing and supporting stability of the vehicle-mounted connecting device and to expand the height and angle adjustment range.

In the vehicle-mounted connection device according to the embodiment of the present invention, the structures of the first connection arm 31 and the second connection arm 32 are not limited to the straight bar shape, but may be other structural shapes. For example, the first connecting arm 31 may be formed with bent portions toward the second connecting arm 32 at positions where the first joint part 10 and the second joint part 20 are connected, respectively, the third pin hole 331 and the fourth pin hole 341 being located on the bent portions; the second connecting arm 32 may be formed with bent portions toward the first connecting arm 32 at positions where the first joint part 10 and the second joint part 20 are connected, respectively, and the third pin hole 332 and the fourth pin hole 342 are located on the bent portions. Alternatively, the first and second connecting arms 31 and 32 are each arc-shaped, and the third and fourth pin holes 331 and 332 and 341 and 342 are located at both ends of the arc-shaped structure, respectively. In this way, even when the first and second link arms 31, 32 are rotated so that the first and second links are on the same line, the two link arms 31, 32 do not block each other, thereby enabling the vehicle-mounted connecting device to obtain a sufficient height and angle adjustment range.

In the particular embodiment shown in the figures, the first connecting arm 31 and the second connecting arm 32 are arranged in parallel and are of equal length. At this time, the first connecting arm 31 and the second connecting arm 32 are straight, and the first connecting arm 31, the second connecting arm 32, a connecting line (first connecting line) of the axes of the first pin 11 and the third pin 21, and a connecting line (second connecting line) of the axes of the second pin 12 and the fourth pin 22 form four sides of a parallelogram together. Such simple structure, processing convenience and be convenient for accomodate.

In the illustrated embodiment, when the first connecting arm 31 and the second connecting arm 32 are parallel to each other and equal in length, the two connecting arms 31 and 32 may be connected to the first joint part 10 and the second joint part 20 in a misaligned state. In this way, it is achieved that the two connecting arms 31 and 32 can also be rotated to a state when the first and second wires are in the same line, without blocking each other, thereby obtaining a greater adjustment range of height and angle, and a compact and aesthetic structure.

The offset connection means that, in the first joint portion 10, the connection line (i.e., the first connection line and the first connection line) of the rotation axes (i.e., the first pin 11 and the third pin 12) of the two connection arms 31 and 32 on the rotation plane is neither parallel nor perpendicular to the installation axis of the first connection structure 41. Similarly, in the second joint section 20, the line (i.e., the first line and the second line) of the rotation axes (i.e., the second pin shaft 21 and the fourth pin shaft 22) of the two connecting arms 31 and 32 on the rotation plane is neither parallel nor perpendicular to the mounting axis of the second connecting structure 42.

Referring to fig. 1, the rotation axes of the first connecting arm 31 and the second connecting arm 32 on the first joint portion 10 are respectively overlapped with the axes of the first pin 11 and the third pin 12, so that the connection line between the first pin 11 and the third pin 12 is equal to the connection line of the two rotation axes on the rotation plane. The connection line is not parallel nor perpendicular to the mounting axis of the first connecting structure 41. Similarly, the rotation axes of the first connecting arm 31 and the second connecting arm 32 in the second joint part 20 are respectively overlapped with the axes of the second pin 21 and the fourth pin 22, and therefore, the connection line between the second pin 21 and the fourth pin 22 is equivalent to the connection line of the two rotation axes on the rotation plane. The line is non-parallel and non-perpendicular to the mounting axis of the second attachment structure 42. This enables the first connecting arm 31 and the second connecting arm 32 to be rotated to a position perpendicular or parallel to the mounting axis without being obstructed by each other. This is shown in fig. 1, i.e. when the two connecting arms 31 and 32 are perpendicular to the mounting axis.

Referring to fig. 5, a perspective view of another using state of the vehicle-mounted fixing device according to an embodiment of the present invention is shown. Fig. 5 shows a state where the first connecting arm 31 and the second connecting arm 32 are approximately parallel to the mounting axis. Likewise, due to the offset design of the two connecting arms 31 and 32, they can be rotated to be parallel to the mounting axis of the first connecting structure 41 and the second connecting structure 42 without being blocked by each other.

In some embodiments, a damping structure is disposed between the first connecting arm 31 and the first joint 10, and between the second connecting arm 32 and the second joint 20. The provision of the damping structure helps the link arms 31 and 32 to remain in their pivoted positions, maintaining their supported condition.

For example, the damping structure may be a rubber sleeve fitted over the pins 13 and 23. The damping structure is simple and easy to implement. However, it should be understood by those skilled in the art that the damping structure is not limited thereto, but may be a glue layer disposed on the inner wall of the pin hole, or any other structure. As long as it is possible to achieve the holding of the connecting arms 31 and 32 at their rotational positions, the specific structure and form thereof are not limited.

However, it should be understood by those skilled in the art that the manner of the fixed connection between each pair of the connecting sheet sets is not limited thereto, and a separate connecting structure may be provided. The connecting structure may also function as a limit stopper to limit the rotation angle of the first connecting arm 31 and the second connecting arm 32 within a certain range.

Referring to fig. 3, an exploded view of another angle of the vehicle-mounted connecting device according to the embodiment of the present invention is shown. In some embodiments, in the vehicle-mounted connection device according to the embodiment of the present invention, the first connection arm 31 and the second connection arm 32 may further have a longitudinal groove, and the longitudinal groove is provided with the reinforcing rib 35.
