Detailed Description

The present invention is further illustrated by way of example and not by way of limitation in the scope of the following examples in connection with the accompanying drawings.

As shown in fig. 1-2, the modular expansion device 100 includes: the housing 110, the module 120, the connecting portion 130, the limiting portion 140 and the elastic portion 170.

The connecting portion 130 is adapted to be fixedly connected to the module 120, and the connecting portion 130 is movable between a retracted position in which the module 120 is retracted into the housing 110 and an extended position in which the module 120 is extended out of the housing 110.

The stopper 140 serves to limit the connecting portion 130 to a retracted position and an extended position, respectively.

The elastic portion 170 biases the connection portion 130 to move the connection portion 130 toward the extended position.

The module telescoping device 100 achieves the telescoping of the module 120 relative to the housing 110 in a purely mechanical manner through the cooperation of the limiting part 140 and the elastic part 170, so that the space occupied by the motor and other electronic components arranged inside the housing 110 is reduced. After the module 120 is pressed, the module 120 may move toward the retracted position against the biasing force of the elastic part 170, and be sequentially restricted to the retracted position and the extended position by the stopper part 140, and thus, the expansion and contraction of the module 120 with respect to the housing 110 may be achieved in a purely mechanical manner.

The housing 110 includes an upper cover 111 and a lower cover 113, and the upper cover 111 covers the lower cover 113 to form the complete housing 110. The upper cover 111 and the lower cover 113 may be detachably connected or may not be detachably connected.

The upper cover 111 has an elastic pressing portion 112, and the elastic pressing portion 112 applies a pressing force to the movable end 143 to move the movable end towards the Y-shaped slide 146. In this way, the movable end 143 can be ensured to always move in abutment with the bottom surface of the Y-shaped slide 146. The elastic pressing portion 112 is not limited to the form shown in fig. 2, and one skilled in the art can select an appropriate elastic pressing portion 112 as needed.

In the present embodiment, the module 120 is a camera module. Alternatively, the module 120 may be a component required by other electronic devices, such as a phone card slot, a sound receiving component, a projector, and so on.

As shown in fig. 3-4, the connecting portion 130 is disposed at one side of the sliding portion 144, and the connecting portion 130 is engaged with the module 120.

The connecting portion 130 includes an elastic sheet 131, the elastic sheet 131 forms a fastening shape, and the side of the module 120 forms a matching shape corresponding to the fastening shape. The elastic piece 131 is easy to deform and replace, and the elastic piece 131 is used for forming a clamping shape, so that the cost can be saved, and the maintenance is easy.

Alternatively, the connecting portion 130 may have other forms, and may be connected to the module 120 in other forms, such as being directly fixed to the module 120 or being clamped to the module 120 without using the elastic piece 131.

As shown in fig. 5 to 8, the stopper portion 140 includes a swing lever 141 and a slide portion 144.

The swing lever 141 is a "C" shaped member. Thus, the fixed end 142 of the swing lever 141 is pivotally connected to the lower cover 113, and the movable end 143 is inserted into the Y-shaped slide 146.

The sliding portion 144 is fixed with respect to the connecting portion 130 and is slidable with respect to the housing 110, a Y-shaped slide 146 is disposed in the sliding portion 144, the fixed end 142 of the swing lever 141 is rotatably connected to the housing 110, the movable end 143 of the swing lever 141 is disposed in the Y-shaped slide 146, and a plurality of steps are disposed in the Y-shaped slide 146 to allow the movable end 143 to slide along a designated path 145.

The designated route 145 is a one-way circulation route, as indicated by the arrows in fig. 3 and 7.

As shown in fig. 5 to 7, a first abutting portion 151 is disposed at the center of the Y-shaped slide rail 146, a second abutting portion 152 is disposed on the bottom surface of the Y-shaped slide rail 146, the movable end 143 abuts against the first abutting portion 151 to limit the connecting portion 130 to the retracted position, and the movable end 143 abuts against the second abutting portion 152 to limit the connecting portion 130 to the extended position. The surface of the first abutment 151 forms a recess 153 to better accommodate the movable end 143.

The Y-shaped slide 146 has four steps, namely a first step 161, a second step 162, a third step 163, and a fourth step 164, which are disposed around the first abutting portion 151. However, the present invention is not limited thereto, and more than four stepped portions may be provided in the Y-shaped slide rail 146 as long as the stepped portions allow the movable end 143 to slide along the designated route 145.

As shown in fig. 5 to 6, in order to form a step for preventing the movable end 143 from moving reversely, the Y-shaped slide 146 forms a plurality of ramps, and after the slide descends across the step, the slide ascends again by the ramps to form another step.

The module 120 extends upward, and the elastic portion 170 is disposed below the connecting portion 130. The extending direction of the module 120 is defined as "upward" to define the relative position of the components of the modular expansion device 100, and does not mean that the module 120 must extend upward as viewed by the user during use.

The elastic part 170 includes a spring 171 and two columns 172 fixing the spring 171, and the spring 171 is always in a compressed state. The form of the elastic part 170 is not limited thereto, and those skilled in the art may change the form of the elastic part 170 as needed.

As shown in fig. 9, the lower cover 113 is provided with a slide rail 114, and the slide portion 144 slides along the slide rail 114.

The operation of the modular jack 100 is briefly described below with reference to fig. 1-9.

In fig. 3, the connecting portion 130 is in a retracted position. The movable end 143 abuts against the first abutting portion 151, and the movable end 143 does not move any more after abutting against the first abutting portion 151 due to the elastic force of the spring 171.

At this time, downward pressure is applied to the module 120, so that the module 120 moves downward, the module 120 drives the connecting portion 130 and the sliding portion 144 to move downward together against the elastic force of the spring 171, at this time, the movable end 143 moves in the Y-shaped slideway 146 in the direction indicated by the arrow to the upper right in fig. 3, due to the blocking of the first step portion 161, the movable end 143 can only move in the direction indicated by the arrow, then the external force is released, the sliding portion 144 and the connecting portion 130 move upward under the elastic force of the spring 171, while the movable end 143 slides downward in the Y-shaped slideway, and due to the blocking of the second step portion 162, moves downward to the second abutting portion 152 along the arrow until abutting against the second abutting portion 152, at this time, the sliding portion 144 moves upward to the highest position, the connecting portion 130 is in the extended position, and the module 120 also pops up.

When downward pressure is applied to the module 120 again, the sliding portion 144 descends, the movable end 143 slides upwards in the Y-shaped slideway 146, the movable end 143 can only enter the left slideway along the arrow due to the blocking of the third step portion 163 and slides to the top, then the external force is released, the sliding portion 144 ascends, the movable end 143 slides downwards in the Y-shaped slideway 146, the movable end 143 abuts against the first abutting portion 151 again due to the blocking of the fourth step portion 164, at this time, the connecting portion 130 is located at the retracted position, and the module 120 retracts into the housing 110.

The modular expansion device 100 can be applied to various electronic terminals, such as mobile terminals and fixed terminals. The fixed terminal may be, for example, a PC, a console, or the like.

The mobile terminal may be a terminal device including a mobile phone, a tablet computer, a PDA (Personal Digital Assistant), a POS (Point of Sales), a vehicle-mounted computer, etc., taking the mobile terminal as an example, and fig. 10 shows a block diagram of a partial structure of the mobile phone 300 related to the mobile terminal provided in this embodiment.
