For the connection manner of the second connecting frame and the second body, reference may be made to the connection manner of the first connecting frame and the first body described above, and details are not described herein again.

Hereinafter, how the mounting assembly 10 solves the interference problem during the opening of the first body 1 will be described with reference to FIGS. 2 to 9.

2 and 3 are cross-sectional views of the side of the terminal device in a closed state and an open state, respectively, of the first body 1 of the terminal device.

It should be understood that FIG. 2 and FIG. 3 illustrate the connection relationship between the first connecting frame 112 and the first body 1 and the second body 2 and the second connecting frame 121 in a screw-locked connection manner. Therefore, the first connecting frame 112 and the second connecting frame 121 are provided with screw holes.

It should be noted that, if the first connecting frame 112 and the first body 1, the first connecting frame 121 and the first body 2 are connected by other means, the first connecting frame 112 and The second connecting frame 121 may not have a screw hole. The connection relationship shown in FIG. 2 and FIG. 3 is merely an example and is not a limitation.

It should also be understood that, in the embodiment of the present application, the second connecting frame 121 may be embedded in the second body 2, in other words, the second connecting frame is not visible from the appearance of the terminal device. 121.

In the embodiment of the present application, the first body 1 and the second body 2 have a gap of a certain width, and the gap line 5 as shown in FIG. 2 and FIG. 3 is the first body 1 and the The gap position between the second bodies 2, the first body 1 and the drive shaft 13 are respectively located on both sides of the gap line. a gap of a certain width between the first body 1 and the second body 2 can ensure that the first body 1 maintains a certain distance from the second body 2 during the opening process, and the transmission The distance from each point on the inner side wall of the arm 111 to the axis of the drive shaft is greater than or equal to the first radius, that is, the inner side wall of the transmission arm 111 coincides with the motion track during the opening of the first body or Outside the trajectory of the movement, it is thereby advantageous to avoid interference problems during the opening of the first body 1.

Optionally, the width of the gap line 5 between the first body 1 and the second body 2 may be less than a certain width threshold, so that, when the first body 1 is in the closed state, the first The gap between a body 1 and the second body 2 is too large, which affects the aesthetic problem.

In the embodiment of the present application, as shown in FIG. 2 and FIG. 3, the second body 2 has a first plane 7 and a second plane. Face 8, the first body 1 has a third plane 9. The second plane 8 of the second body 2 is a plane in which the first body 1 is in a closed state, and the second body 2 is in contact with the first body 1. During the opening of the first body 1, the third plane 9 of the first body 1 is away from the second plane 8 of the second body 2, close to the first plane 7 of the second body 2.

Since the first connecting frame 112 is located between the second plane 8 of the second body 2 and the third plane 9 of the first body 1 when the first body 1 is in the closed state. In order to ensure that the first body 1 is in the closed state, the gap between the first body 1 and the second body 2 in the direction perpendicular to the second plane 8 is as small as possible, that is, the first body 1 The gap between the third plane 9 and the second plane 8 of the second body 2 can be as small as possible. A groove of a certain depth may be disposed on a plane in which the second body 2 is in contact with the first connecting frame 112, that is, the second plane 8, so that the first connecting frame 112 may be partially or wholly located in the Within the recess, the thickness of the first connecting bracket 112 may be set as small as possible.

For example, the groove 6 shown in FIG. 2 or FIG. 3, when the first body 1 is closed, the first connecting frame 112 may all be located in the groove 6 of the second body 2, thereby ensuring When the first body 1 is in the closed state, the third plane 9 of the first body 1 and the second plane 8 of the second body 2 have the smallest gap in the direction perpendicular to the second plane 8.

4 is a side view showing a possible structure of the terminal device in a closed state of the first body 1. It should be understood that FIG. 4 only shows a schematic view of some components that need further explanation, not shown. A component does not mean that the terminal device does not include the component.

As shown in FIG. 4, the depth d of the groove 6 provided on the second plane 8 of the second body 2 is greater than the thickness h of the first connecting frame 112, so that when the first body 1 is closed, The first connecting frame 112 is all located in the groove 6. Thus, the third plane 9 of the first body 1 and the first plane 7 of the second body 2 may be in the same plane, ie the first plane 7 and the second plane 8 of the second body 2 are perpendicular to The difference in height between the first plane 7 or the second plane 8 is the thickness of the first body 1.

Alternatively, as shown in FIG. 5, the third plane 9 of the first body 1 may also be higher than the first plane 7 of the second body 2, for example, the first plane 7 and the second body 2 The two planes 8 can be in the same plane, such that the height of the third plane 9 of the first body 1 above the first plane 7 of the second body 2 is the thickness of the first body 1. Next, the third plane 9 of the first body 1 and the first plane 7 of the second body 2 can be brought as close as possible to one plane by reducing the thickness of the first body 1.

Optionally, the depth of the groove on the second body 2 may also be smaller than the thickness of the first connecting frame 112, such that the first connecting frame 112 is partially located in the groove of the second body 2. The second plane 8 of the second body 2 is partially protruded. In this case, in order to ensure that the first body 1 is in a closed state, the gap between the first body 1 and the second body 2 in a direction perpendicular to the second plane 8 is as small as possible, that is, the first The gap between the second plane 8 of the body 1 and the third plane 9 of the second body 2 is as small as possible, and the thickness of the first connecting frame 112 can be set as small as possible, that is, by reducing the number The thickness of a connecting frame 112 achieves the purpose of reducing the gap between the first body 1 and the second body 2 in the closed state.

In this case, when the first body 1 is closed, the first connecting frame 112 all protrudes from the plane in which the second body 2 is located, and FIG. 6 shows the second body 2 A side view of the terminal device when the first body 1 is in a closed state, FIG. 6 only shows a schematic view of a part of the components that need further explanation, and a component not shown does not represent the terminal device. This component is not included.

As shown in FIG. 6, when the second body 2 is not provided with a groove, the third plane 9 and the first body 1 are in a direction perpendicular to the second plane 8 of the second body 2. The gap between the second planes 8 of the second body 2 is the sum of the thickness h of the first connecting frame and the thickness of the first body 1. In this case, the third plane 9 and the second body of the first body 1 in the closed state can be reduced by reducing the thickness of the first connecting bracket 112 or the thickness of the first body 1.

This is because, during the rotation of the first body 1, the arc 4 formed by the rotation of the position point of the point 31 is the smallest.

In order to ensure that the second body 2 does not interfere with the transmission arm 111 during the rotation of the first body 1, the first body 1 may be disposed closest to the axis of the drive shaft 13 and the highest The trajectory of the point 31, that is, the arc 4 does not interfere with the trajectory of the transmission arm 111. Then, the distance from each point on the transmission arm 111 to the axis of the drive shaft 13 is required to be greater than or equal to the distance from the point 31 to the axis of the drive shaft 13, ie, each of the upper portions of the transmission arm 111.
