Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 3, an embodiment of the present invention discloses a shielding case and an electronic device having the shielding case. Electronic equipment generally includes a circuit board on which electronic components are disposed, and a shield case covering the electronic components and shielding the electronic components on the circuit board; the shield case includes a frame body 100, a cover body 200, and a stopper 300.

When an electronic device works, an electronic component generates electromagnetic waves, which generate electromagnetic interference to other components outside a circuit board, and accordingly, the electronic component on the circuit board is also easily subjected to electromagnetic interference from other components, so that the electronic component on the circuit board needs to be electromagnetically shielded in order to ensure that the electronic component can normally operate. In the present embodiment, the electromagnetic shielding is realized by the shielding case.

At present, a shielding cover is usually an integral structural member, and is bonded on a circuit board during installation, and when the shielding cover needs to be disassembled (for example, during maintenance of electronic equipment), the bonding position of the shielding cover needs to be heated and baked, which is usually realized by blowing hot air with a hot air gun, so that the circuit board is overheated, and the circuit board and electronic elements thereon are damaged; meanwhile, the disassembly mode also has the problem of low efficiency. In view of this, the main body of the shielding case disclosed in this embodiment is composed of the frame body 100 and the cover body 200, i.e., a split structure is adopted.

The frame 100 has a first receiving space 110 and an opening 120, and the opening 120 is communicated with the first receiving space 110. It should be understood that the shielding case is usually combined with the circuit board to form a shielding space, so as to electromagnetically shield the electronic components disposed on the circuit board; the first receiving space 110 is the shielding space. In the present embodiment, the bottom surface of the housing 100 may not be provided when the shield case is combined with the circuit board, but the presence or absence of the bottom surface of the housing 100 is not limited.

As shown in fig. 1 and 2, the frame 100 may be provided with a threaded mounting hole, and may be connected to the circuit board by a threaded fastener. Of course, the present embodiment does not limit the specific connection relationship between the frame 100 and the circuit board, for example, the two may be connected by bonding, snapping, SMT soldering, or the like.

The cover 200 is detachably disposed on the frame 100 and covers the opening 120. It should be understood that the cover 200 covers the opening 120 when being installed, so that no electromagnetic leakage is caused, and a better electromagnetic shielding effect is ensured.

Meanwhile, as described above, the shielding case has a split structure, and during a specific working process (e.g., during a maintenance process), an operator only needs to detach the cover body 200 from the frame body 100 to observe the electronic components inside the shielding case through the opening 120, so that the operations such as inspection and maintenance can be smoothly performed. Therefore, the shielding case disclosed by the embodiment does not need to be heated and baked when being detached, the circuit board and the electronic element are prevented from being damaged, the rejection rate of the circuit board is reduced, and meanwhile, the working efficiency is also improved.

In the embodiment, the limiting element 300 is movably disposed on the frame 100, and the limiting element 300 has a first state and a second state, that is, in the first state and the second state, the limiting element 300 is located at two different positions relative to the frame 100.

When the limiting member 300 is in the first state, the limiting member 300 moves into the opening 120 and abuts against the cover body 200 to fix the cover body 200. As mentioned above, since the cover 200 covers the opening 120, the cover 200 is at least partially disposed in the opening 120, and when the position-limiting member 300 moves into the opening 120 and presses against the cover 200, the cover 200 can be reliably fixed, so that the shielding cover has a better shielding effect. In this process, the limiting member 300 covers the cover 200 in the direction perpendicular to the circuit board, i.e. the limiting member 300 is usually located above the cover 200.

When the limiting member 300 is in the second state, the limiting member 300 moves out of the opening 120 to release the cover 200. Specifically, when the stopper 300 moves out of the range of the opening 120, that is, there is no abutting connection with the lid 200, the stopper is no longer stopped with respect to the lid 200, and therefore, the lid 200 can be smoothly detached, and the inside of the shield can be observed to inspect and repair the electronic component.

As can be seen from the above description, in the embodiment of the present invention, the shielding cover adopts a split structure, and the cover 200 covers the opening 120, so as to ensure that the shielding cover has a better shielding effect; meanwhile, when the limiting member 300 is in the first state, the cover 200 can be pressed and fixed, and the cover 200 can be prevented from falling off from the frame 100; when the stopper is in the second state, it moves out of the opening 120, and at this time, the cover 200 is in an unrefined state, so that it can be easily detached from the housing 100. By switching the state of the stopper 300, the cover 200 can be easily attached to and detached from the housing 100, and when the cover 200 is detached, the electronic components in the shield can be observed, and inspection, maintenance, and other operations can be smoothly performed.

Compared with the prior art, the embodiment of the utility model discloses a shield cover has higher dismantlement efficiency undoubtedly, need not heat simultaneously and toast, has avoided circuit board and electronic component's damage.

In this embodiment, the specific connection relationship of the cover 200 on the frame 100 is not limited, for example, the limiting member 300 can be clamped on the frame 100 at the first position and the second position, and can press the cover 200 to fix the cover 200 when clamped at the first position.

In one embodiment, the position-limiting member 300 can be slidably engaged with the frame 100, that is, the state of the position-limiting member 300 can be switched by sliding engagement. Compared with other connection relations, the sliding fit relation undoubtedly has more convenient operability, and the working efficiency can be optimized.

Of course, in the present embodiment, there are various sliding fit relations between the limiting member 300 and the frame body 100, for example, a sliding fit can be realized by arranging a ball between the end of the limiting member 300 and the frame body 100. In a specific embodiment, the frame body 100 may be provided with a guide rod 130, the guide rod 130 extends along a sliding direction of the limiting member 300, the limiting member 300 has a sliding hole 310 matching with the guide rod 130, and the limiting member 300 is sleeved on the guide rod 130 through the sliding hole 310.

It should be understood that the sliding hole 310 can slide on the guide rod 130, so as to realize the relative sliding of the limiting member 300 on the frame body 100, and switch between the first state and the second state. Meanwhile, the guide bar 130 has a guiding function, so that the stopper 300 can be prevented from deviating from the sliding track.

It should be noted that the specific position of the sliding fit relationship between the limiting member 300 and the frame 100 is not limited in this embodiment. As shown in fig. 2, the guide rod 130 is disposed on the inner surface of the frame body 100, so that the limiting member 300 is slidably fitted on the inner surface of the frame body 100; however, the guide bar 130 may be provided on the outer surface of the housing 100 as long as the stopper 300 can slide.

In order to make the limiting member 300 have a larger moving space and a more balanced pressing effect on the cover 200, in an alternative scheme, the limiting member 300 may be a limiting rod, and two ends of the limiting rod are slidably fitted to the frame body 100. It should be understood that, in the present embodiment, there is no limitation on the specific type of the limiting member 300, for example, the limiting member 300 may also be a block shape, a bent shape capable of being engaged with the peripheral side of the cover body 200, or the like. In specific working process, when the limiting rod is pressed on the cover body 200, the cover body 200 is limited in the length direction of the limiting rod, so that the cover body 200 is prevented from being in a serious unbalanced state, and the installation stability of the cover body 200 is optimized.

Referring to fig. 2, in an alternative scheme, the number of the limiting rods can be two. In a specific working process, when the cap body is in the first state, the two limiting rods can respectively slide to the two opposite ends of the cap body 200, and compress and fix the cap body 200. Thus, the limiting effect of the cover body 200 is balanced, and the installation stability of the cover body 200 is further optimized. Of course, the specific number of the limiting members 300 is not limited in this embodiment, and may be three, four, or other numbers.

In the electronic device, the electronic device is usually turned or moved, and in this case, the stopper 300 is easily displaced relative to the cover 200. Based on this, in order to prevent the limiting element 300 from slipping out of the cover 200 and losing the limiting and fixing effects on the cover 200 in the first state, as shown in fig. 3, in an alternative scheme, the limiting element 300 may be provided with an anti-slip cushion layer 320 on an end surface facing the cover 200. It should be understood that the anti-slip pad 320 can increase the mutual friction between the limiting member 300 and the cover 200, and certainly can effectively prevent the limiting member 300 and the cover 200 from sliding relatively in the first state.

In this embodiment, the anti-skid pad layer 320 may be made of a rubber material, or may be made of other materials such as foam, and the specific material type of the anti-skid pad layer 320 is not limited in this embodiment.

Referring to fig. 1, in an alternative embodiment, a supporting portion 140 may be disposed on an inner surface of a sidewall of the frame 100, and the cover 200 is overlapped on the supporting portion 140, that is, the supporting portion 140 is a mounting supporting base of the cover 200. Specifically, with such a configuration, the cover 200 is located in the first accommodating space 110, and separates the electronic component from the external space of the shielding case, thereby achieving the shielding effect; meanwhile, the peripheral side of the cover body 200 is surrounded by the frame body 100, and the frame body 100 can play a role in restricting and limiting the cover body 200, compared with the case that the cover body 200 is directly overlapped on the opening 120, the shield cover disclosed in the embodiment can prevent the cover body 200 from shifting, thereby avoiding a gap from occurring between the cover body 200 and the frame body 100 and ensuring that the shield cover has a better shielding effect.

In general, the supporting portion 140 is disposed adjacent to the opening, so as to facilitate taking and placing the cover 200, maximize the first receiving space 110, and improve the receiving capability of the shielding case. In combination with the above, no gap is formed between the cover 200 and the frame 100, and in this case, the cover 200 can completely cover the opening 120.

Of course, the specific type of the supporting portion 140 is not limited in this embodiment, for example, the supporting portion 140 may be a plurality of supporting blocks arranged at intervals in the same plane. In one embodiment, the supporting portion 140 may have a ring shape and extend along the inner surface of the sidewall of the frame body 100. Specifically, the supporting portion 140 may be an annular supporting base that protrudes from the inner surface of the sidewall of the frame 100, and when the cover 200 is attached to the supporting portion 140, the supporting portion can provide a relatively comprehensive supporting function for the whole cover 200.

When the position-limiting element 300 is slidably engaged with the inner surface of the sidewall of the frame 100, in the second state, if the position-limiting element 300 is still in the opening 120, the operation of taking and placing the cover 200 may be interfered, i.e. it is difficult to take out or place the cover 200 through the opening 120. Based on this, in an alternative scheme, the inner surface of the sidewall of the frame body 100 may be provided with a second receiving space 150 for receiving the limiting member 300, the second receiving space 150 is communicated with the first receiving space 110, and the second receiving space 150 is located on the moving path of the limiting member 300. Based on the above configuration, the stopper 300 can be smoothly moved into the second receiving space 150 to be received.

In a specific working process, after the cover 200 is placed in the first accommodating space 110, the limiting member 300 can be switched to the first state, the limiting member 300 moves from the second accommodating space 150 to the first accommodating space 110, that is, the limiting member 300 is located in the opening 120, and at this time, the limiting member 300 can press and fix the cover 200; when the cover 200 needs to be taken out, the limiting member 300 is switched to the second state, and the limiting member 300 moves from the first accommodating space 110 to the second accommodating space 150, that is, the limiting member 300 is located outside the opening 120, and at this time, the limiting member 300 does not interfere with the taking out of the cover 200.

In general, the second receiving space 150 may be adapted to the shape and size of the limiting member 300. The second receiving space 150 may also be disposed adjacent to the opening 120, so that the cover 200 may be placed closer to the opening 120 to improve the receiving capability of the shielding case. As mentioned above, in the embodiment using the guide bar 130, the guide bar 130 needs to extend into the second receiving space 150, so that the limiting member 300 can smoothly slide into the second receiving space 150.

In order to further improve the installation stability of the cover body 200 and avoid the cover body 200 from deviating and displacing, in an alternative scheme, the edge of the cover body 200 may be provided with a clamping portion 210, the inner surface of the frame body 100 located at the opening 120 is provided with a clamping matching portion 160, and the clamping portion 210 and the clamping matching portion 160 may be in clamping matching. Specifically, when the clamping portion 210 and the clamping portion 160 are clamped, the two are mutually limited, so that the connection relationship between the cover 200 and the frame 100 is more stable.

In this embodiment, the specific types of the clip portion 210 and the clip mating portion 160 can be various, for example, one of the clip portion 210 and the clip mating portion 160 is a convex structure, and the other is a concave structure. Of course, the raised structures and the recessed structures match each other. As shown in fig. 2, the clamping portion 210 is a limit protrusion, and the clamping matching portion 160 is a limit groove.

When the heat inside the shielding case is too much, the temperature will rise, and the electronic components will be damaged. Based on this, in order to facilitate the dissipation of heat inside the shield, in an alternative scheme, the frame body 100 may have a heat dissipation hole 170, and the heat dissipation hole 170 is communicated with the first receiving space 110. So, under the circumstances of guaranteeing the shielding effect, accelerated the gas circulation, when the inside heat of shield cover is more, unnecessary heat can be discharged through louvre 170, can effectively avoid the inside temperature rise of shield cover. Of course, the present embodiment does not limit the specific number of the heat dissipation holes 170.

Please refer to fig. 2 again:

in one embodiment, the limiting member 300 may be provided with a control portion 330. When the operation is performed, the control portion 330 can improve the convenience of operating the position limiting member 300, so as to optimize the experience of the operator. Of course, the type of the control portion 330 may be various, and the present embodiment does not limit it, for example, the control portion 330 may be a bump, a handle, or the like.

In another embodiment, an auxiliary hole 180 may be disposed on a sidewall of the frame body 100, and the auxiliary hole 180 communicates with the second receiving space 150. It should be understood that when the limiting member 300 is located in the second receiving space 150, it is inconvenient to control the limiting member 300 to move out of the second receiving space 150. In the embodiment, the limiting member 300 can be manually acted on the limiting member 300 through the auxiliary hole 180, so that the limiting member 300 is pushed out from the second accommodating space 150, and the operation convenience of the limiting member 300 is optimized.

The embodiment of the utility model provides an electronic equipment that indicates can be equipment such as smart mobile phone, panel computer, electronic book reader, wearable device, and the embodiment of the invention does not limit the concrete kind of electronic equipment.

The utility model discloses what the key description in the above embodiment is different between each embodiment, and different optimization characteristics are as long as not contradictory between each embodiment, all can make up and form more preferred embodiment, consider that the literary composition is succinct, then no longer describe here.
