The mobile communication terminal 50 of this example shown in the figure is a semi-automatic sliding mobile communication device. The user only needs to push the upper frame 60 to a certain extent in the sliding direction, and the remaining part can rely on the elasticity accumulated when the user pushes the frame 60. The restoring force automatically moves to complete the opening and closing of the terminal 50 .

Semi-automatic sliding type mobile communication terminal 50 of the present invention is made of lower frame 70 and upper frame 60; Lower frame 70 is equipped with keyboard input device 71 and main system, and upper frame 60 links to each other with the top of lower frame 70, with Carry out sliding linear movement, and be equipped with a main display screen 61 and a plurality of function keys 63 .

The mobile communication terminal 50 of the present invention is equipped with a tool for realizing sliding movement of the rack and a tool for automatically opening and closing to accumulate elastic recovery force. In addition, the sliding moving tool and the elastic restoring force accumulating tool of the mobile communication terminal 50 in this example are attached to the contact surfaces of the upper and lower frames 60, 70 with additional panels.

The lower frame 70 of the present example is provided with a first slide plate 75, and the upper frame 60 is fixedly provided with a second slide plate 65 with a screwdriver.

In order to realize the linear sliding movement of the first sliding plate 75 fixedly arranged on the lower frame 70 to both sides, a "匚" shape guide groove 76 is provided upward; the two ends of the second sliding plate 65 are provided with an insertion guide groove Guide rod 68 that can slide in 76.

The center of the first sliding plate 75 is provided with a control plate groove for the guide rod 68, and a curved guide cam 77 is provided along the right side wall of the control plate groove. The guide cam 77 of this example is in a curved shape with narrower front and rear ends and wider toward the middle. This structure can accumulate elastic restoring force when the cam follower 66 to be described below passes through the curved guide cam 77 .

On the left side wall of the second sliding plate 65 of this example, a cam follower 66 is fixedly arranged, and the cam follower can accumulate elastic recovery for the automatic sliding of the upper frame 60 while moving along the guide cam 77. force.

The cam follower 66 of this example includes two parts, a follower plate 67 and an elastic tool. The driven plate 67 is directly connected to the above-mentioned guide cam 77, and moves along its curved shape; one end of the elastic tool is fixed on the left side wall of the second sliding plate 65, and the other end is connected to the above-mentioned driven plate 67 to accumulate elastic recovery. force.

The above-mentioned driven plate 67 in this example is a self-rotating rotating wheel centered on the rotating shaft 67a penetrating through the elastic tool, and it relies on the friction generated during the curved movement of the guide cam 77 to rotate.

The elastic tool of this example is that one end is fixed on the left side wall of the 2nd slide plate 65, and the other end is fixed on the guide rod 68 on the above-mentioned driven plate 67, and its inside is provided with the long guide groove 69 of left and right direction, guide groove 69 guides the follower plate 67 to move left and right when the cam follower 66 moves along the curved shape of the guide cam 77 .

In addition, a spring 64 is provided inside the guide groove 69, the spring 64 contracts when the driven plate 67 moves to the left, and the spring 64 relaxes when the driven plate 67 moves to the right.

Therefore, when the terminal 50 is opened and closed, before the cam follower 66 reaches the bending point of the guide cam 77, the spring 64 is in a contracted state to accumulate elastic restoring force. After crossing the bending point, the spring 64 releases the accumulated elastic restoring force and releases, so that the driven plate 67 moves to the right.

In addition, in the process of the driven plate 67 moving to the right, under the guidance of the guide cam 77, the sliding in the front and rear direction also occurs continuously, and the upper and lower frames 60, 70 attached to the sliding control plates 65, 75 also slide automatically. , so that the terminal 50 can be opened and closed.

Serrations 77a are designed on the bend of the guide cam 77 in this example, and the outer surface of the driven plate 67 is also designed with serrations 67b that engage with the serrations 77a of the guide cam 77 .

According to an example, a configuration in which the driven plate 67 does not rotate is also possible, in which case the friction between the guide cam 77 and the driven plate 67 is expected to be negligibly small.

On the other hand, like this example, the driven plate 67 is set to the situation that can rotate, and the outer surface between the guide cam 77 and the driven plate 67 forms a friction surface, and when the guide cam 77 moved, the driven plate 67 was Rotation also occurs under the action of frictional force, as above, it is also possible to form sawtooth 67b that occludes each other.

The terminal 50 of this example also sets the bending point in front of the entire sliding track, so as to ensure faster and more convenient operation when opening the terminal. Therefore, when opening the terminal 50, even if the user moves only a short distance, the bending point can be quickly passed, and the terminal 50 can be quickly opened in the event of an emergency.

Next, the operation of the semiautomatic sliding type mobile communication terminal of the present example having the above construction will be described.

When using the terminal 50 of this example to make a call, the upper frame 60 is pushed backward.

When the cam follower 66 moves toward the bending point of the guide cam 77, the follower plate 67 moves to the left on the guide groove 69, and the spring 64 built in the guide groove 69 contracts to accumulate elastic restoring force.

At the moment when the driven plate 67 passes the bending point of the guide cam 77, the spring 64 is in the state of maximum contraction. After crossing this point, the elastic restoring force accumulated on the spring 64 is released, and the spring 64 begins to relax.

At the same time, the cam follower 66 is fixedly installed on the upper frame 60, and as the cam follower 66 moves rearward along the guide cam 77, they become one and move backward together, and the lower frame 70 The keyboard input device 71 is exposed on the surface.

After using the exposed keyboard input device 71 to operate the terminal 50 for the desired purpose, push the upper frame 60 forward so that the upper frame 60 covers the keyboard input device 71 again. At this time, as long as the user applies a certain degree of thrust to the upper frame 60, the cam follower 66 will cross the bending point, and then the upper frame 60 uses the elastic restoring force accumulated in this process to automatically complete the remaining track sliding.

During this process, the upper frame 60 has been moved to the position where the keyboard input device 71 of the lower frame 70 is completely covered, and then the terminal 50 is turned into a closed state.

Fig. 6a is a perspective view of the lower frame of the semi-automatic sliding mobile communication terminal according to the second embodiment of the present invention. Fig. 6b is a perspective view of the upper frame of the semi-automatic sliding mobile communication terminal according to the second embodiment of the present invention.

At this time, the slide bar 61' coincides with the slide groove 71' of the lower frame 70', and can slide in the front-rear direction.

In addition, a slot with a certain width in the front-rear direction is provided on the top of the lower frame 70 ′, and a curved guide cam 77 ′ corresponding to the guide cam 77 in the above example is arranged on the right side wall of the slot.

In the upper frame 60' of this example, there is also a groove of a certain width along the front-rear direction, and a cam follower 66' that accumulates elastic restoring force in the left-right direction when moving along the guide cam 77'.

The cam follower 66 ′ in this example includes a guide rod 68 ′ extending outward from the left side wall of the groove provided on the upper frame 60 ′, and a follower plate 67 rotatable toward the right end of the guide rod 68 ′. `. A guide groove 69 ′ that guides the driven plate 67 ′ to move left and right in the length direction is also installed on the guide rod 68 ′. A spring 64 ′ is arranged on the guide groove 69 ′, which shrinks or releases along with the left and right movement of the driven plate 67 ′, so that the frame can move automatically.

On the outer surface of the driven plate 67 ′ of this example and the curved shape of the guide cam 77 ′, there are interlocking serrations 67 ′ b, 77 ′ a, and the driven plate 67 ′ moves along with the guide cam 77 ′. Simultaneously, it rotates around the rotation shaft 67'a, and elastically moves in the left and right directions.

If the user's thrust reaches a certain level specified by the upper frame 60', so that the driven plate 67' crosses the bending point of the guide cam 77', then under the action of the elastic restoring force accumulated in the spring 64', the upper The frame 60' will move through the remaining sliding track, so that the terminal 50 can be opened and closed automatically.

According to the above-mentioned structure, when the sliding terminal is opened and closed, a certain degree of thrust is first applied, and as the cam follower moves along the guide cam, under the action of the elastic restoring force accumulated in the cam follower, the terminal The rack slides by itself, thus realizing the automatic opening and closing of the terminal. This configuration can bring convenience to the user of the terminal.

The above specific embodiments are only used to illustrate the present invention, but not to limit the present invention.
