In one embodiment, the engaging portion 330 is a substantially rectangular block structure. The end of the engaging portion 330 away from the first side surface 303 is chamfered, so that the end of the engaging portion 330 away from the first side surface 303 forms a second inclined surface 330 a.

Referring to fig. 8, when the card cover 20 covers the bottom cover 101, the engaging portion 330 of the slider 30 engages with the engaging portion 202 of the card cover 20. When the dial 310 on the slider 30 slides away from the card cover 20 under an external force, the latch portion 202 is separated from the engaging portion 330, and the card cover 20 can be separated from the bottom cover 101.

When the card cover 20 is closed, the bottom surface 211 of the main body 201 is close to the bottom wall 115a of the groove 115 by an external force, and the second inclined surface 330a abuts on the first inclined surface 221 and moves toward the bottom surface 211 of the main body 201.

Referring to fig. 7 and 9, the second side 304 of the slider 30 is provided with an abutting post 340. The abutment post 340 serves to prevent the second side 304 of the slider 30 from directly colliding with the bottom cover 101 when the slider 30 is slid to be separated from the card cover 20.

In one embodiment, the abutting columns 340 on the second side 304 partially extend into the receiving slots 111 on the first connecting portion 116. When the slider 30 slides to be separated from the bottom cover 101, the abutting columns 340 abut against the groove walls of the accommodating grooves 111. Optionally, when the slider 30 slides to be separated from the bottom cover 101, the abutting column 340 abuts on a groove wall of the accommodating groove 111 opposite to the opening of the accommodating groove 111.

The slider 30 slides along a slide groove 119 formed between the inner surface 101a of the bottom cover 101, the second connecting portion 117, and the third connecting portion 118. Specifically, the third side surface 305 of the slider 30 is slidably connected to a surface of the second connecting portion 117 facing the third connecting portion 118. The fourth side 306 of the slider 30 is slidably connected to a surface of the third connecting portion 118 facing the second connecting portion 117. The sliding groove 119 is formed between the second connecting portion 117 and the third connecting portion 118, so that the third side surface 305 of the slider 30 and the fourth side surface 306 of the slider 30 can slide along the groove wall of the sliding groove 119, and the stability of the slider 30 in the sliding process is further improved.

In the related art, the housing 10 of the electronic device 100 is opened and a grip is reserved around the opening to facilitate the user to detach the card cover 20 from the housing 10 to mount a Subscriber Identity Module (SIM). However, the hand-picking position is reserved around the hole, which damages the complete shape of the product appearance, and the opening of the card cover is time-consuming and labor-consuming, thus being inconvenient for the user to operate.

By arranging the sliding block 30, the sliding block 30 is clamped with the card cover 20 in the inner cavity 104 of the shell 10, so that the card cover 20 is prevented from falling off from the bottom cover 101; one end of the slider 30 is at least partially located in the second through hole 112 of the bottom cover 101, when the slider 30 outside the bottom cover 101 is pushed under an external force, the slider 30 slides in a direction away from the card cover 20, and the slider 30 is separated from the card cover 20, so that the card cover 20 is easily taken out of the bottom cover 101, the appearance smoothness of the electronic device 100 is ensured, and the operation of opening and closing the card cover 20 is simple.

Optionally, as shown in fig. 10, the housing assembly 1 may further include a fixing base 40. Specifically, the anchor 40 is secured within the interior 104.

An accommodating space 401 is formed between the fixing base 40 and the inner surface 101a of the bottom cover 101. It can be understood that the receiving space 401 is a space area between the fixing base 40 and the inner surface 101a of the bottom cover 101 in the inner cavity 104. The slider 30 is located in the accommodating space 401. Two opposite sides of the sliding block 30 are slidably connected to the fixing base 40 and the inner surface 101a of the bottom cover 101, respectively. In one embodiment, opposite sides of the slider 30 contact a surface of the fixing base 40 facing the bottom cover 101 and an inner surface 101a of the bottom cover 101, respectively. Of course, in other embodiments, the sliding block 30 and the fixing seat 40 may be connected by a sliding way.

In an embodiment, referring to fig. 10 and 11, the fixing base 40 includes a first fixing portion 402 and a second fixing portion 403 connected to each other. The first fixing portion 402 is substantially in the shape of a long bar. A receiving space 401 is formed between a side of the first fixing portion 402 facing the bottom cover 101 and the inner surface 101a of the bottom cover 101. The slider 30 is slidably coupled to the inner surface 101a of the bottom cover 101 and a surface of the first fixing portion 402 facing the bottom cover 101, respectively. The second fixing portion 403 is disposed opposite to the locking portion 202. The second fixing portion 403 encloses a substantially annular cavity 431.

By providing the fixing base 40 in the housing assembly 1, a receiving space 401 is formed between the fixing base 40 and the inner surface 101a of the bottom cover 101, which can be used for receiving the slider 30 to avoid interference with other components when the slider 30 slides in the inner cavity 104. Further, the opposite sides of the slider 30 are slidably connected to the fixing base 40 and the inner surface 101a of the bottom cover 101, so that the slider 30 can slide along the fixing base 40 and the inner surface 101a of the bottom cover 101, thereby ensuring the stability of the slider 30 during the sliding process. In addition, the fixed base 40 and the inner surface 101a of the bottom cover 101 also have a supporting function for the slider 30.

Alternatively, the first fixing portion 402 and the inner surface 101a of the bottom cover 101 are connected to each other through the first connecting portion 116, the second connecting portion 117 and the third connecting portion 118, so that the fixing base 40 is fixed in the inner cavity 104 through the first connecting portion 116, the second connecting portion 117 and the third connecting portion 118.

Optionally, referring to fig. 10 and 11, a slide rail 404 is disposed on a side of the first fixing portion 402 facing the inner surface 101a of the bottom cover 101. The slider 30 is slidably connected to the first fixing portion 402 via a slide rail 404. The sliding rail 404 may protrude from the first fixing portion 402 or may be recessed into the first fixing portion 402. In one embodiment, the first fixing portion 402 has two protrusions 440 disposed opposite to each other. The sliding rail 404 is formed between the two convex parts 440 and the surface of the first fixing part 402. The second end face 302 of the slider 30 partially extends between the two protrusions 440 of the first fixed portion 402. The slider 30 slides while abutting the two protrusions 440 of the first fixing portion 402.

By providing the slide rail 404 such that the slider 30 moves along the slide rail 404, the stability of the slider 30 during sliding can be further improved. In addition, the slider 30 moves on the slide rail 404, and when the slide rail 404 extends along a straight line, the slider 30 can be ensured to move along the straight line, and further, the reliability of the clamping between the slider 30 and the card cover 20 can be ensured in the process of multiple times of use.

Further, referring to fig. 11 and 12, the housing assembly 1 may further include a first elastic member 50. The first elastic element 50 is elastically abutted between the fixed seat 40 and the card cover 20. The first elastic element 50 is at least partially received in the cavity 431 of the second fixing portion 403.

In one embodiment, the first elastic element 50 is a spring. The first elastic member 50 is located between the inner surface 101a of the bottom cover 101 and the fixing base 40. One end of the first elastic element 50 is connected to the buckling part 202 of the card cover 20 and connected to an end surface of the buckling part 202 opposite to the inner surface 101a of the bottom cover 101.

Wherein "the bottom surface of the cavity 431" refers to the surface opposite to the opening of the cavity 431.

As shown in fig. 13, when the slider 30 and the card cover 20 are in the engaged state, the first elastic element 50 is in a compressed state. When the slider 30 slides away from the card cover 20 under an external force, the slider 30 is separated from the card cover 20, the first elastic member 50 is extended under the elastic force, so that the end of the card cover 20 connected with the first elastic member 50 is bounced, and the card cover 20 is separated from the bottom cover 101 when bounced. An external force acts on the card cover 20 to pull the card cover 20 outward, so that the card cover 20 gradually moves away from the bottom cover 101 until the boss 230 of the card connecting portion 203 abuts against the inner surface 101a, at which time the card cover 20 is in an open state. The body 201 and the latch 202 are located outside the bottom cover 101.

In one embodiment, when the card cover 20 is elastically deformed by the elastic restoring force of the first elastic member 50, one end of the body portion 201 of the card cover 20 is located outside the bottom cover 101. The latch portion 202 of the card cover 20 is partially located in the first through hole 110.

Through the arrangement of the first elastic member 50, when the slider 30 and the card cover 20 are separated from each other, the card cover 20 can be bounced by the first elastic member 50, so that the card cover 20 can be automatically opened, and a user can open the card cover 20 conveniently.

Further, referring to fig. 11, the housing assembly 1 further includes a second elastic member 60. The second elastic element 60 is elastically abutted between the slider 30 and the first connecting portion 116. The second elastic member 60 is at least partially received in the receiving groove 111 of the first connecting portion 116.

In one embodiment, referring to fig. 7 and 12, the second elastic element 60 is a spring. The second elastic member 60 is located between the third side 305 of the slider 30 and the first connecting portion 116. One end of the second elastic member 60 is connected to the abutment post 340 of the third side surface 305. The opposite end of the second elastic member 60 is connected to the wall of the receiving groove 111 of the first connecting portion 116.

Referring to fig. 14 and 15, by applying an external force to the shifting block 310, the sliding block 30 slides away from the card cover 20 under the action of the external force, the sliding block 30 applies a resisting force to the second elastic member 60, so that the second elastic member 60 is compressed, when the shifting block 310 is shifted to separate the sliding block 30 from the card cover 20, the first elastic member 50 is extended again under the action of the elastic force, so that the end of the card cover 20 connected with the first elastic member 50 is bounced, and a part of the card cover 20 is protruded from the bottom cover 101 when bounced.

By applying a pulling force to the card cover 20, the card cover 20 is pulled out with respect to the bottom cover 101 until the boss 230 of the card portion 203 abuts against the inner surface 101a, at which time the card cover 20 is in an open state. The body 201 and the latch 202 of the card cover 20 are located outside the bottom cover 101. At this time, the subscriber identity card can be attached and detached.

When the user identification card is mounted and dismounted, the pushing force is applied to the card cover 20 to push the card cover 20 to approach the bottom cover 101 until the card cover 20 is engaged with the sliding block 30. In the process of pushing the card cover 20 to approach the bottom cover 101 until the card cover 20 is engaged with the slider 30, the first inclined surface 221 slides along the second inclined surface 330a until the engaging portion 330 of the slider 30 is engaged with the engaging groove 220.

By providing the second elastic member 60, it is possible to have an effect of reducing the buffering and damping when the slider 30 moves. In addition, when the slider 30 and the card cover 20 are in the engagement state, the second elastic element 60 is in the compression state, which can increase the engagement force between the slider 30 and the card cover 20, so that the engagement portion 330 of the slider 30 abuts against the engagement portion 202 of the card cover 20, thereby improving the engagement effect between the slider 30 and the card cover 20.

The foregoing is a partial description of the present application, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present application, and these modifications and decorations are also regarded as the protection scope of the present application.
