Detailed Description

To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. It is obvious that the described embodiments 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.

As shown in fig. 1 to 3, an embodiment of the present invention discloses an electronic device, which includes a middle frame 100, a display panel 200, a first ground portion 300, and a second ground portion 400.

The middle frame 100 can provide a mounting position for other components of the electronic device, in an embodiment of the present invention, the display screen 200 is disposed on one side of the middle frame 100, and the first ground portion 300 is disposed on one side of the middle frame 100 departing from the display screen 200.

The display screen 200 may be an OLED (Organic Light-Emitting Diode) screen, and compared with the display screens 200 having other structures, the OLED screen has a better Light-Emitting effect, and meanwhile, the OLED screen has the advantage of being Light and thin. Of course, the display screen 200 may be further configured as a flexible screen, and the flexible screen may enable the electronic device to be foldable, so that the size of the screen of the electronic device is increased and the electronic device is convenient for a user to carry; the flexible screen can also prevent that electronic equipment from dropping and leading to display screen 200 to damage, and then promotes display screen 200's life.

The display panel 200 needs to be reliably grounded, and specifically, the first grounding portion 300 has a grounding surface 310, the middle frame 100 has an avoiding hole 110, a first end of the second grounding portion 400 is connected to the display panel 200, a second end of the second grounding portion 400 passes through the avoiding hole 110, and the second end of the second grounding portion 400 is electrically connected to the grounding surface 310, so that the display panel 200 is grounded through the second grounding portion 400.

As can be seen from the above, in the electronic device disclosed in the embodiment of the present invention, the second grounding portion 400 on the display screen 200 passes through the avoiding hole 110 and is electrically connected to the first grounding portion 300 on the side of the middle frame 100 deviating from the display screen 200, so that the display screen 200 realizes the grounding process. Under the condition, the installation position of the grounding structure is changed, so that the thickness of the structure formed by the display screen 200 and the middle frame 100 is more uniform, the display screen 200 can be prevented from being deformed and even damaged, and the reliability of the display screen 200 and the appearance performance of the electronic device are improved.

Further, on the surface of the middle frame 100 facing away from the display screen 200, the orthographic projection of the ground plane 310 may be located outside the orthographic projection of the avoiding hole 110. In this case, the pressing force of second ground portion 400 to first ground portion 300 is small, so that the pressing force of second ground portion 400 to display screen 200 is small, and thus the influence of first ground portion 300 and second ground portion 400 on the assembly of display screen 200 is small, and furthermore center 100 can better support display screen 200, so that display screen 200 is less likely to deform, and finally, the reliability of display screen 200 and the appearance performance of the electronic device can be better.

Based on this, the second ground part 400 may be electrically connected to the ground plane 310 through a conductive paste. Since the conductive adhesive has an elastic expansion effect, the second ground portion 400 can be properly shortened, and the elastic deformation of the conductive adhesive ensures reliable connection between the second end of the second ground portion 400 and the ground plane 310. When the user presses the display screen 200, the second end of the second grounding portion 400 can move along the direction of the pressing force, and the conductive adhesive can properly recover the deformation, but can be always matched with the ground plane 310. Therefore, this scheme not only enables the second end of the second ground portion 400 to have better connection reliability with the ground plane 310, but also prevents the generation of a redundant second ground portion 400, thereby more reliably preventing the display screen from being deformed or even damaged.

Further, the conductive adhesive may be plugged at an end of the avoiding hole 110 away from the display screen 200. Under the condition, the inner wall of the avoiding hole 110 and the conductive adhesive form an accommodating space, when a user presses the display screen 200, the redundant second grounding part 400 can be accumulated in the accommodating space, so that the uniformity of the thickness of the structure formed by the display screen 200 and the middle frame 100 can not be influenced, the second end of the second grounding part 400 can be prevented from extending out to one side of the middle frame 100 deviating from the display screen 200, the second grounding part 400 is prevented from influencing the parts arranged on one side of the middle frame 100 deviating from the display screen 200, and the safety of the electronic equipment is improved.

In the embodiment of the present invention, the second end of the second grounding portion 400 can be electrically connected to the ground plane 310 in a plurality of ways, for example, the second end of the second grounding portion 400 can be fixed to the ground plane 310 by bonding or welding, so that the second end of the second grounding portion 400 is electrically connected to the ground plane 310. Of course, in order to reduce the installation process, the second end of the second ground portion 400 may be a conductive end having an elastic deformation effect, specifically, the second end may pass through the avoiding hole 110, and the second end may contact the ground surface 310 through elastic deformation of the elastic member between the second end and the ground surface, so that the second ground portion 400 and the ground surface 310 are electrically connected. In this case, the second grounding portion 400 can be tightly fitted with the ground plane 310 by the elasticity of the elastic conductive end, so that the assembling process of the electronic device can be reduced, and the cost can be saved.

With the above structure, if the ground plane 310 is coplanar with at least a portion of the inner surface of the avoiding hole 110, the elastic deformation of the elastic end is substantially not released, and the elastic conductive end is easily damaged under long-term pressure, which may cause a failure in the contact between the second end of the second ground portion 400 and the ground plane 310. Therefore, on the surface of the middle frame 100 facing away from the display screen 200, the orthographic projection of the ground plane 310 may have a space from the orthographic projection of the avoiding hole 110. Based on this, in a specific application process, since the orthographic projection of the ground plane 310 and the orthographic projection of the avoiding hole 110 have a gap therebetween, the elastic end has a certain release amount, and thus the elastic end can be prevented from being damaged due to long-term compression, and the elastic end can be in good contact with the ground plane 310.

In the embodiment of the present invention, the specific shape of the first grounding portion 300 may be various, for example, the first grounding portion 300 may be a bar-shaped structure or a ring-shaped structure, optionally, the first grounding portion 300 may be a ring-shaped structure, as shown in fig. 4, and the ring-shaped structure may be disposed around the avoiding hole 110. In this case, the inner surface of the annular structure is the ground plane 310, that is, the inner wall of the hole formed by the annular structure is the ground plane 310, so that the ground plane 310 can be disposed around the avoiding hole 110, and the area of the ground plane 310 is larger. When the second end of the second ground portion 400 passes through the avoiding hole 110, the second end of the second ground portion 400 is easily contacted with the ground plane 310 in this way, so that the second ground portion 400 is easily electrically connected with the ground plane 310.

Further, when the second end of the second ground portion 400 passes through the avoiding hole 110, in order to make the second end of the second ground portion 400 easily contact the ground plane 310 so as to electrically connect the second ground portion 400 and the first ground portion 300, on the surface of the middle frame 100 departing from the display screen 200, the orthographic projection contour of the inner surface of the annular structural member may coincide with the orthographic projection contour of the avoiding hole 110. In this case, since the orthographic projection contour of the inner surface of the annular structure overlaps the orthographic projection contour of the escape hole 110, the inner surface of the annular structure and the inner surface of the escape hole 110 are completely coplanar, and even if there is a machining error or an assembly error between the first ground connection portion 300 and the second ground connection portion 400, the second end of the second ground connection portion 400 can be easily brought into contact with the ground plane 310. Therefore, this configuration has low requirements for the machining accuracy and the mounting accuracy of the first ground connection portion 300 and the second ground connection portion 400, and facilitates the machining and molding of the first ground connection portion 300 and the second ground connection portion 400 and the assembly of the electronic device. Meanwhile, in a specific machining process, the annular structural member and the avoiding hole 110 can be integrally formed, so that the cost can be saved.

In the embodiment of the present invention, the number of the first grounding parts 300 and the second grounding parts 400 can be a plurality of, each first grounding part 300 can be disposed at intervals, each second grounding part 400 can be disposed at intervals, and each first grounding part 300 can be electrically connected with at least one second grounding part 400 correspondingly. The plurality of first ground parts 300 and the plurality of second ground parts 400 enable more ground points of the display screen 200 than the display screen 200 implements the ground processing by one first ground part 300 and one second ground part 400, thereby enabling the ground processing to be implemented more reliably.

The utility model discloses an embodiment, on the surface that deviates from display screen 200 at center 100, the orthographic projection of ground plane 310 can be located outside the orthographic projection of dodging hole 110 to make second ground portion 400 less to the pressing force of display screen 200. In this case, on the surface of the middle frame 100 facing away from the display screen 200, there may be a gap between the orthographic projection of the ground plane 310 and the orthographic projection of the avoiding hole 110, or there may be no gap between the orthographic projection of the ground plane 310 and the orthographic projection of the avoiding hole 110.

In an alternative, there may be no space between the orthographic projection of the ground plane 310 and the orthographic projection of the avoiding hole 110, that is, the ground plane 310 and at least a part of the surface of the avoiding hole 110 may be coplanar, which enables the second end of the second ground part 400 to easily contact the ground plane 310, so that the second end of the second ground part 400 is electrically connected to the ground plane 310. Meanwhile, in a specific processing process, the first ground portion 300 may be fixed to the middle frame 100 by welding, bonding, or the like, and the ground plane 310 may be integrally formed with the avoiding hole 110, so that cost may be saved.

Further, the shape of the avoiding hole 110 may be various, such as a rectangular hole, a polygonal hole, and the like. The ground plane 310 may be a plane, and the ground plane 310 may be coplanar with one of the inner surfaces of the avoidance hole 110. In this case, since the ground plane 310 and the inner surface of the avoiding hole 110 are both planar, the ground plane 310 and the inner surface of the avoiding hole 110 are easily flush.

In the embodiment of the present invention, in order to prevent the deformation of the display screen 200 to a greater extent, the ground plane 310 may extend in a direction parallel to the axis of the avoiding hole 110. Based on this, when the second end of the second grounding portion 400 passes through the avoiding hole 110, since the ground plane 310 extends along the direction parallel to the axis of the avoiding hole 110, the acting force applied to the second end of the second grounding portion 400 in the axis direction of the avoiding hole 110 is smaller, so that the pressing force applied to the display screen 200 is smaller, and finally the deformation of the display screen 200 can be better prevented.

In order to enable the second end of the second ground portion 400 to be electrically connected to the first ground portion 300 more reliably, the second end of the second ground portion 400 may be provided with a first limiting portion, the first ground portion 300 may be provided with a second limiting portion, and the first limiting portion and the second limiting portion are matched to limit. In this case, the second end of the second ground portion 400 and the first ground portion 300 can be in limit fit by the first limit portion and the second limit portion, so that the second end of the second ground portion 400 and the first ground portion 300 can be electrically connected more reliably. Based on this, in first spacing portion and second spacing portion, one can be the recess, and another can be the joint arch, and the joint arch can cooperate with the recess joint, and of course, first spacing portion and the spacing portion of second also can be other structures, the embodiment of the utility model provides a do not restrict the concrete structure of first spacing portion and the spacing portion of second.

Meanwhile, since the thickness of the first ground portion 300 is small, the thickness of the structure formed by the second end of the second ground portion 400 and the first ground portion 300 is small under the condition that the second end of the second ground portion 400 is bent to the side of the first ground portion 300 departing from the display screen 200, thereby being beneficial to the light and thin design of the electronic device.

The utility model discloses an embodiment, first ground connection portion 300 and second ground connection portion 400 can integrated into one piece, and under this kind of condition, first ground connection portion 300 has better connection reliability with second ground connection portion 400. Meanwhile, in the process of processing, the first and
