sides

134, 135 are the long sides of the electronic device 100. Typically, a pair of

sides

134, 135 are used to arrange volume keys, card holders, etc. of the electronic device 100. Top edge 132 and bottom edge 133 are the short sides of electronic device 100. Generally, bottom edge 133 is used to route earpieces, speakers, etc. of electronic device 100. The structure of the housing 11 can be a variety of different shapes, and the structure of the housing 11 includes, but is not limited to, the following several embodiments.

In a first embodiment, referring to fig. 5, the receiving groove 13a is disposed on the top edge 132, and the receiving groove 13a penetrates the pair of side edges 134 and 135.

In the electronic device 100, the accommodating groove 13a is formed on the top edge 132, so that when the sliding seat 2 is slidably connected to the device main body 11, the display module 12, the sliding seat 2 and the housing 11 in the electronic device 100 form a sandwich structure. This structure has guaranteed that when electronic device 100 takes place to fall or receives external force collision, display module assembly 12 and casing 11 can provide the protection to the sliding seat 2 that is located wherein, prevents that sliding seat 2 from breaking.

Specifically, the length of the housing groove 13a in the X direction is the same as the length of the apparatus main body 11 in the X direction. In other words, the portions of the two

side edges

134, 135 of the frame 12 adjacent to the top edge 132 form two openings due to the accommodating groove 13a, so that the sliding seat 2 corresponding to the accommodating groove 13a has a larger volume to accommodate more functional devices 6. Correspondingly, the more functional devices 6 are arranged in the sliding seat 2, the less the functional devices 6 have influence on the screen ratio of the display module 12 of the electronic device 100.

In the second embodiment, referring to fig. 11, different from the first embodiment, the receiving groove 13a is disposed on the rear shell 11, and the edge of the receiving groove 13a extends to the top edge 132. The sliding seat 2 and the device body 1 are mutually spliced in the Y direction, and cannot be overlapped in the Z direction, so that the electronic device 100 formed after the sliding seat 2 and the device body 1 are spliced is lighter and thinner.

In the third embodiment, referring to fig. 12, different from the first embodiment, the receiving groove 13a is disposed on the rear shell 11, and three edges of the receiving groove 13a extend to the top edge 132 and the pair of side edges 134 and 135. The sliding seat 2 and the device main body 1 are mutually spliced in the Y direction and cannot be superposed in the Z direction, so that the electronic device 100 formed after the sliding seat 2 and the device main body 1 are spliced is lighter and thinner, the sliding seat 2 has a larger size in the X direction, the sliding seat 2 has a larger accommodating space, more functional devices 6 can be accommodated, more functional parts 6a are not required to be arranged on the display module 12, and the screen occupation ratio of the display module 12 is further reduced.

In each of the above embodiments, the slide holder 2 has a size corresponding to the receiving groove 13a, i.e., the slide holder 2 fills the entire receiving groove 13 a. The sliding seat 2 has a first end face 2 a. When the first end surface 2a of the sliding seat 2 is flush with the top edge 132, it is defined that the sliding seat 2 is completely accommodated in the accommodating groove 13a, in other words, the sliding seat 2 is in a retracted state; when the first end surface 2a of the sliding seat 2 exceeds the top edge 132, it is defined that the sliding seat 2 protrudes out of the accommodating groove 13a, in other words, the sliding seat 2 is in a protruding state.

When a certain functional device 6 in the sliding seat 2 is required to operate, the sliding seat 2 can be correspondingly slid, so that the sliding seat 2 is in an extended state. At this time, the functional part 6a of the slide base 2 is not covered by the display screen, and the functional device 6 corresponding to the functional part 6a can transmit a signal to the outside. For example, the plurality of functional devices 6 may include a front camera device, and correspondingly, the functional portion 6a of the sliding seat 2 corresponding to the front camera is a front transparent portion capable of transmitting light to the front camera device. When the function of the front camera needs to be used, the sliding seat 2 is slid, so that the sliding seat 2 is in an extended state, the photographing function of the front camera can be realized through the front light-transmitting part, and when the function of the front camera does not need to be used, the sliding seat 2 is slid, so that the sliding seat 2 is in a retracted state, the electronic device 100 is favorably stored, and the portability of the electronic device 100 is improved.

It is understood that the functional portion 6a of the slide base 2 is different from the functional device 6, and the signal that the functional portion 6a can transmit is different from the functional device 6. For example, the signal that can be transmitted through the functional unit 6a corresponding to the camera assembly 51 is light, and the signal that can be transmitted through the functional unit 6a corresponding to the receiver 52 is sound.

In one embodiment, the slide base 2 has two oppositely disposed light-transmissive glass surfaces for transmitting light through the functional device 6 in the slide base 2 without providing a light-transmissive portion at a position corresponding to the functional device 6.

In another embodiment, the light-transmitting panel is disposed on a local area on the surface of the sliding seat 2 to form the functional portion 6a, and the light-transmitting panel is disposed on the local area, so that the cost of the electronic device 100 is less and the strength of the sliding seat 2 is higher.

The foregoing is a preferred embodiment of the present application, and it should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of the present application, and these improvements and modifications are also considered as the protection scope of the present application.
