detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The invention provides an electronic device housing, comprising a front shell, a middle shell and a rear shell, as shown in FIG. 1 is a schematic structural view of a middle shell, the middle shell comprising:

a metal component 100 located inside;

a plastic part 200 located in the middle and connected to the metal part 100;

An outer casing 300 that is externally attached to the plastic component 200.

The middle case of the traditional electronic device is made of plastic material. When the plastic material supports it, its strength is difficult to meet the requirements. When it slides down to the ground, it is easy to break, and the user can show that the outer surface can only be plastic, and the plastic surface is not well formed. .

Therefore, the present invention divides the middle shell into a three-part structure, and the inside thereof is a metal member 100. The metal member 100 is mainly supported in the middle shell. Since the metal itself is relatively hard and has characteristics higher than the strength of the plastic, the material is changed. The strength of the rear middle shell is higher than that of the traditional middle shell. The plastic part 200 located in the middle mainly serves to connect the metal part 100 and the plastic part 300.

The traditional middle case is a one-piece structure. Since the inner case itself is made of a plastic material, the outer surface thereof can only be made of a plastic material. In the present invention, the metal part 100 and the outer case 300 are separated, so the material of the metal part 100 does not affect. The material of the outer casing 300 may be made of various materials such as metal, glass or leather. Because different shell materials are different for different users, the present invention can adopt different material shells in processing the middle shell according to user requirements, so as to meet the needs of various customers, and the user experience is better.

According to the above, the housing provided by the invention can meet the requirements of the strength of the casing and has good surface forming quality. Among them, the outer casing can select different treatment methods and processes to achieve different industrial design effects according to the effects required by the industrial design.

The electronic device housing provided by the present invention comprises a front shell, a middle shell and a rear shell. The above content is to introduce the structural composition of the middle shell. The following describes how the middle shell is connected with the front shell 400 and the rear shell 500 to form a complete case.

As shown in FIG. 2, the metal component 100 includes:

a screw hole 105 is disposed on the first side of the metal component 100, and the screw hole 105 is sized to match the first through hole 401 of the front casing buckle 404, and the screw 402 can penetrate the first through hole 401 and the screw hole 105 fixes the front case 400.

The front housing 400 includes a plurality of front housing buckles 404. The middle housing has a screw hole 105 at a position corresponding to the front housing buckle 404. The screw 401 is fastened through the front housing and then locked in the screw hole 105. The front case 400 and the middle case are defined. It can be understood that the depth of the screw hole 105 is greater than the length of the screw 402. When the screw 401 is slightly too long due to the precision, the screw hole 402 can be completely inserted into the screw hole 105, and the shape is not formed. The phenomenon of screw bulging. The screw hole 105 can be obtained by tapping.

In addition, referring to FIG. 2, the front casing buckle 404 is a Z-shaped metal buckle, and the bent portion of the Z-shaped metal buckle cooperates with the display screen of the front casing. The front casing buckle 404 is a Z-shaped bent metal foil, and the Z-shaped bend is for avoiding the display screen so that the display screen has enough space to be placed in the front casing.

The manner in which the middle case and the front case 400 are connected in the above embodiment is as follows. The manner in which the middle case is connected to the rear case 500 is as follows. As shown in FIG. 3, the first side of the metal part is provided with a card with a rear case. The groove 501 is fitted by the claw 501. The metal member includes an L-shaped claw 108 for engaging with the rear case claw 501.

The rear case 500 is fastened to the middle case, and is engaged with the middle case by the form of the rear case claw 501. In order to make the manner of the snap connection more stable, the metal part 100 further includes an L-shaped claw 108 through the L-shaped card. The claws 108 and the rear case claws are engaged with each other to fix the rear case 500. In the specific implementation, the inventors of the present invention have found that when the rear case claw 501 is engaged with the metal member 100, the space inside the metal member 100 is insufficient, so that the groove 107 is provided on the first side of the metal member as the rear case claw 501. The escaping is so that the rear case claw 501 is completely engaged with the metal member 100.

The L-shaped claw 108 may be formed by bending the metal member 100 by a metal bending process, or may be formed by other means, for example, additionally processing a bent L-shaped claw and connecting the L-shaped claw to the metal member 100. When the metal component 100 is L-shaped, the plastic component 200 may be wrapped around the bend of the L-shaped metal component. This has two advantages. When using the injection molding process, high precision can be achieved, so the accuracy of the gap between the middle case and the rear case 500 can be improved, and the back case 500 can utilize the gap and the middle case card. Combined, two can strengthen the fixed gold The function of the component 100.

The above embodiment details the middle case, and the cooperation of the middle case with the front case and the back case. The housing of the electronic device usually needs to be combined with other parts inside the electronic device, as shown in FIG. 4, including the metal part 100. The connected tablet 600, where the tablet 600 can be a touch panel or a circuit panel, can be connected to the metal component 100 by soldering.

Preferably, as shown in FIG. 5, the present invention further provides an electronic device housing, wherein the metal member 100 is a side wall formed by bending the flat plate 600. That is, one side of the flat plate 600 is bent by a metal bending process to form a side wall, and the side wall is used as the first metal member 100. This method can omit the process of soldering the first metal member 100 to the flat plate 600.

The middle casing comprises three parts, a metal part 100, a plastic part 200 and a casing, wherein the metal part 100 comprises at least one layer of metal parts, and the plastic part 200 comprises at least one layer of plastic parts, that is, a layer of metal parts and two layers of metal Pieces...multi-layer metal parts, one layer of plastic parts, two layers of plastic parts...multi-layer plastic parts, of course, the number of metal parts and the number of plastic parts are not infinite, only the number can be more than here. The number of metal parts and plastic parts inside the metal part and the plastic part is not limited.

The metal component 100 and the plastic component 200 in the present invention have various connection forms, and specifically include:

The first type: connecting the metal component to the plastic component by means of glue sticking;

The second type: connecting the metal component to the plastic component by ultrasonic welding;

Third: When a plastic part is formed outside the metal part by an injection molding process, the metal part is connected to the plastic part.

Different implementations have the beneficial effect that, in general, the side of the metal part 100 It is flat and unnotched, and there is no disadvantage when it is connected by means of glue sticking or ultrasonic welding, but when the metal part 100 and the plastic part 200 are connected by an injection molding process, if the side of the metal part 100 is flat, When the plastic component 200 is attached to the metal component 100 after injection molding, it is easy to fall off due to insufficient gripping force. Therefore, the present invention also provides a metal component 100 including a gripping structure.

In order to achieve a strong gripping force, the gripping structure is capable of realizing the following components: the opening on the second side of the metal part is small, and the opening on the first side of the metal part is large, that is, the shape of the gripping structure is a tapered structure. Therefore, when the plastic part is formed by the injection molding process, the plastic is poured into the gripping structure, so that the plastic part is obtained after the injection molding is completed, and the metal part 100 is firmly grasped, and it is not easy to fall off. The side of the metal component 100 that is connected to the plastic component 200 is the second side of the metal component, and the other side of the metal component 100 is the first side of the metal component.

In order to realize the gripping structure, as shown in FIG. 6, the metal part 100 includes:

At least one gripping groove 101 disposed on a first side of the metal component 100; a second through hole 102 disposed at a position corresponding to the gripping groove 101 on a second side of the metal component, and the second The through hole 102 is smaller than the gripping groove 101;

A rubber gripping groove 101 and a second through hole 102 form a gripping structure. In order to achieve a strong gripping force, a plurality of gripping grooves 101 and a plurality of second through holes 102 may be disposed on the metal component 100. Therefore, a plurality of gripping structures are formed, and the plurality of gripping structures can be evenly distributed on the entire circumference of the middle shell, so as to achieve the purpose that the plastic component 200 and the metal component 100 are not easily peeled off, thereby allowing the outer casing 300 and the metal component 100 to be stably combined. Together.

Since the conventional processing technology cannot realize the tapered structure in one processing, the present invention realizes the gripping structure by combining the gripping groove 101 and the second through hole 102. With Body, as shown in FIG. 6, a gripping groove 101 is disposed on a first side of the metal member, a second through hole 102 is disposed on a second side of the metal member, and the second through hole 102 passes through the gripping groove 101, and The two through holes 102 are smaller than the gripping groove 101, and the combination of the two forms a rubber-like structure similar to a taper. The use of the gripping structure solves the problem that the plastic part 200 and the metal part 100 are easily detached.

Since the metal component 100 includes at least one layer of metal, the gripping structure can also be implemented in other manners. For example, the metal component 100 is composed of two separate metal parts, and two kinds of rubber gripping structures can be used for the two metal parts. :

First: as shown in FIG. 7, the metal member 100 includes a first metal member 103 and a second metal member 104 connected to the first metal member 103; the first metal member 103 is provided with at least one rubber The second metal member 104 is provided with a second through hole 102 smaller than the gripping groove 101 at a position corresponding to the gripping groove 101.

Second: As shown in FIG. 8, the metal member 100 includes a third metal member 301 and a fourth metal member 302 connected to the third metal member 301.

At least one gripping groove 101 disposed on a first side of the fourth metal member 302; a second through hole 102 at a position corresponding to the gripping groove 101 on a second side of the fourth metal member 302, and The second through hole 102 is smaller than the gripping groove 101.

The side of the fourth metal member 302 that is connected to the plastic member 200 is the second side of the fourth metal member, and the other side of the fourth metal member 302 is the first side of the fourth metal member.

The second way is the improvement of the first method. In the first method, it is necessary to make a through hole on one metal member, and then to make a groove on another metal member, which is cumbersome and is not conducive to mass production. In the second method, the gripping structure can be disposed on the fourth metal member, and it is not necessary to process both metal parts, and the design is optimized in the process.

In addition, the present invention requires an auxiliary structure on the middle casing to be connected to other components. In the first mode, an auxiliary structure is required on the first metal member, since the first metal member itself has been used as a gripping groove, and then In order to prevent the first metal member from being broken when processing the auxiliary structure, it is necessary to thicken the thickness of the first metal member, and in the second manner, the auxiliary structure such as the groove and the second groove may be formed on the third metal member, due to the third There is no processed gripping structure on the metal member, so the thickness of the metal member 100 is reduced relative to the first mode.

When the metal parts are three layers, four layers or multiple layers, the structure of the rubber material may be referred to as a two-layer structure. The specific implementation is similar to the above, and will not be repeated here.

The three implementations of the gripping structure of the metal component 100 are described above, and the same gripping structure can be achieved regardless of the manner in which the different gripping structures are different. The structure of the second through hole 102 may be various, as long as the second through hole 102 is smaller than the gripping groove 101. Preferably, the second through hole 102 may be circular, rectangular or triangular. When the metal component 100 includes two layers of metal members, preferably, the first metal member 103 and the second metal member 104 are connected in a welded manner, and the third metal member 301 and the fourth metal member 302 are The welding method is connected. The joints are welded together to make the combined dimensions of the two have higher precision and can reduce the dimensional error.

In addition, the first metal member 103, the second metal member 104, the third metal member 301, and the fourth metal member 302 are sheet metal thin metal sheet metal, and the thickness of the thin metal is usually less than 6 mm, thereby The thickness of the housing is thin and the user experience is better.

In FIGS. 2 and 3, how the middle case is connected to the front case 400 and the rear case 500 is described as a whole with the metal member 100. Since the metal part 100 includes at least one metal piece, the metal part 100 includes two underneath. The layer metal member is taken as an example for description, and the third metal member is equivalent to the first metal The fourth metal member 302 is equivalent to the second metal member. Therefore, the first metal member 103 and the second metal member 104 are exemplified as an example, when the metal member is three layers, four layers or multiple layers. The specific implementation form is similar to the two layers of content, and will not be described here:

As shown in FIG. 9, when the metal member 100 is a combination of two thin metal members, the first metal member 103 includes: a screw hole 105 disposed in the first metal member 103, the screw hole 105 and the front The first through holes 401 of the case buckles are uniform in size, and the screws 402 can fix the front case 400 through the first through holes 401 and the screw holes 105. The second metal member 104 includes a second recess 106. When the length of the screw 401 is too long, the excess portion can enter the second recess 106 of the second metal member 104 to prevent the occurrence of the screw protrusion.

In addition, as shown in FIG. 9 , the front cover buckle is a Z-shaped metal buckle, and the bend of the Z-shaped metal buckle cooperates with the display screen of the front cover. The front case snaps into a Z-shaped bent foil, and the Z-bend is to avoid the display so that the display has enough space to be placed in the front case.

In the manner in which the middle case and the front case 400 are connected in the above embodiment, the manner in which the middle case and the rear case 500 are connected is described below. When the metal part 100 includes two metal parts, the first metal part and the second metal may be used. The case is illustrated as an example:

As shown in FIG. 10, the following describes the manner in which the middle case is connected to the rear case 500, including:

The first metal member 103 is provided with a groove 107 that cooperates with the rear case claw 501, and the second metal member 104 includes an L-shaped claw 108 for the rear case. The claw 501 is engaged, and the plastic part 200 wraps the bend of the L-shaped claw 108 of the second metal piece.

The advantage of using two metal parts can be seen in FIG. 10: the groove 107 can be machined only on the first metal part 103 to achieve the cooperation with the rear case claw 501, and only the second metal piece 104 can be folded. The bending process forms the L-shaped claws 108 to achieve the snap fit with the rear casing claws 501. It not only saves metal materials, but also has the advantage of simple processing.

The above embodiment details the middle case, and the cooperation of the middle case with the front case and the rear case. The housing of the electronic device usually needs to be combined with other parts inside the electronic device, including the connection with the metal part 100 and by welding. The flat plate 600, when the metal member is a combination of two metal members, as shown in FIG. 11, the connection manner of the flat plate 600 includes: a flat plate connected to the first metal member 103 and the second metal member 104 by welding. 600. The tablet 600 here may be a touch panel or a circuit panel.

Preferably, as shown in FIG. 12, the present invention further provides an electronic device housing, wherein the first metal member 103 includes a sidewall formed by bending a flat plate, since the first metal member 100 needs to be combined with the flat plate 600. Connected, the flat plate 600 can be combined with the first metal member 100, that is, one side of the flat plate 600 is bent by a metal bending process to form a side wall, and the side wall is used as the first metal member 100. This method can omit the process of soldering the first metal member 100 to the flat plate 600.

The above is the structure of the electronic device housing. The electronic device housing of the present invention is a ferroplastic combined housing with good strength, thin sidewalls and low cost.

The structure of the metal component 100 is described in detail in the above embodiment. The outer casing 300 is exposed on the outer surface of the electronic device for viewing by the user. The material of the outer casing includes: metal, glass or leather. Different materials show different display effects.

The outer casing 300 is connected to the metal component 100 through the plastic component 200, and can be specifically used in three ways:

The first way: the plastic component 200 is connected to the outer casing 300 by glue bonding;

First in the way of glue bonding, ultrasonic welding or injection molding process in metal parts 100 and plastic The rubber member 200 is joined, and then the outer casing 300 is adhered to the plastic member 200 with a strong glue. The manner in which the glue is adhered is not reliable, so the present invention provides a second way.

The second way: connecting the plastic component to the outer casing by ultrasonic welding;

First, the metal component 100 is connected to the plastic component 200 by means of glue bonding, ultrasonic welding or injection molding, and then the outer casing 300 is welded to the plastic component 200 by ultrasonic welding. The advantage of the welding method is that it does not fall off. And the process is more convenient.

Both of the above two methods require two steps to fix the outer casing, and the following one-step manner is provided, that is, the third way: forming the plastic component 200 by the injection molding process and connecting the metal component 100 and the outer casing 300, the plastic component 200 is connected to the outer casing 300; the metal component 100 and the outer casing 300 are fixed by a bracket, and the fixed metal component 100 and the outer casing 300 together with the bracket are placed in an injection mold, and the plastic component 200 is formed by an injection molding process. The component 200 connects the metal component 100 on the one hand and the outer casing 300 on the one hand, thereby realizing the fixing of the outer casing 300.

The material of the outer casing may also be a plastic material. When the outer casing 300 is plastic, a plastic (ie, a plastic component 200) and a two-shot plastic (ie, the outer casing 300) may be formed on the outer side of the metal component 100 by a two-shot injection molding process. There is a plastic and a two-shot plastic on the outside of the metal component 100, and the two plastic processes have a high molding quality on the surface of the casing.

When the metal component 100 is connected to the plastic component 200, any one of three methods of glue, ultrasonic welding and injection molding may be used. When the plastic component 200 is connected to the outer casing 300, any of the above three methods may also be adopted, so that the middle casing There are 3*3=9 kinds of ways to connect the three parts. In the specific implementation, the three parts of the middle case can be connected together by using any one of nine connection methods.

The present invention can fix the outer casing 300 by the above three methods. The material of the outer casing 300 can be various, and since the customer's requirements are inconsistent, the same process can be used to meet the needs of different customers, in the traditional plastic material. The shell can not meet the various needs of customers. If a metal shell is required, it can only be manufactured with metal materials. The invention adopts the same process flow to meet the needs of different customers, and the process is simple.

When the metal component 100 includes the third metal component 301 and the fourth metal component 302, and the outer casing 300 is also plastic, the middle casing can be processed by the following method. As shown in FIG. 13, the present invention provides an electronic device in the casing. Manufacturing methods, including:
