Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a housing structure, a housing structure manufacturing method and a mold, and electronic equipment. Background Art

[0002] With the popularization of electronic devices, such as mobile phones and tablet computers, people have put forward higher requirements for the appearance design, structural strength and user experience of electronic products. In electronic devices such as mobile phones and tablet computers, the shell of the electronic device is particularly important, which is used to carry various components. In order to improve the strength of the shell, optimize signal transmission, etc., some shells adopt a structure that combines metal and plastic, that is, they are manufactured by metal insert injection molding; wiring grooves are generally designed on the shell for installing electrical connection lines, and the groove depth direction of the wiring groove is the thickness direction of the shell. In this way, when manufacturing the shell, the mold insert used to form the wiring groove will be designed with a thinner insertion structure, and the insertion structure will rub or collide with the metal part of the shell as an insert, making the insertion structure of the mold insert prone to breakage, reducing the life of the mold insert. Summary of the invention

[0003] The present application provides a shell structure, a shell structure manufacturing method, a mold, and an electronic device to solve the technical problem in the related art that a mold insert used to form a wiring groove is prone to breakage, thereby reducing the life of the mold insert.

[0004] The technical solution is as follows:

[0005] In a first aspect, the present application provides a housing structure for an electronic device, the housing structure comprising: a first housing portion and a second housing portion;

[0006] The first housing portion includes a first frame, the first frame is used to enclose a mounting cavity, the first frame has a first side surface and a second side surface opposite to each other, the first side surface faces the mounting cavity, and the second side surface faces away from the mounting cavity;

[0007] The second shell portion includes a second frame having a third side surface and a fourth side surface opposite to each other. The second frame is located on the side where the second side surface is located. The third side surface contacts the second side surface. A first wire groove is formed on the fourth side surface.

[0008] By adopting the above technical scheme, on the first hand, the first wire groove is arranged on the fourth side surface, so that the insert of the mold used does not need to be designed with a thinner insertion structure, which reduces the impact and friction between the inserts, thereby reducing the possibility of insert breakage and increasing the service life of the insert, thereby increasing the life of the mold and facilitating the manufacture of the shell structure; on the second hand, the third side surface is in contact with the second side surface, and the first wire groove is located on the fourth side surface, which also makes the second frame equivalent to the structure of an I-beam, so that when the shell structure is subjected to a force parallel to the thickness direction of the shell structure, the bending resistance of the shell structure can be improved; on the third hand, the transmission line in the first wire groove and the components in the installation cavity can be isolated from each other, which is beneficial to reduce the influence between them.

[0009] In some implementations, the first frame further includes a first top surface;

[0010] The second side surface includes a first sub-surface and a second sub-surface, the second sub-surface and the first top surface are respectively connected to the first sub-surface, the first sub-surface and the second sub-surface are non-parallel to each other, and the second sub-surface and the first top surface have a height difference in the thickness direction of the shell structure;

[0011] The first sub-surface and the second sub-surface are in contact with the third side surface respectively.

[0012] By adopting the above technical solution, by providing a height difference between the second sub-surface and the first top surface so that the third side surface contacts the first sub-surface and the second sub-surface respectively, the contact area between the third side surface and the second side surface is increased, thereby improving the strength of the combination between the first frame and the second frame, and increasing the overall stiffness and stability formed by the combination of the first frame and the second frame, which is beneficial to increasing the load.

[0013] In some implementations, a groove depth direction of the first wire groove is non-parallel to a thickness direction of the shell structure.

[0014] By adopting the above technical solution, it is beneficial to enhance the strength and stability of the shell structure, and the existence of the first wire groove can disperse the stress to a certain extent, thereby improving the pressure resistance of the shell structure.

[0015] In some implementations, an angle formed between a groove depth direction of the first wire groove and a thickness direction of the shell structure is a right angle or an acute angle.

[0016] By adopting the above technical solution, better structural support and stability can be provided, thereby enhancing the overall strength of the shell structure, thereby improving the ability of the shell structure to resist external pressure or impact load; and when the angle between the groove depth direction of the first wire groove and the thickness direction of the shell structure is a right angle, it is also beneficial to reduce the complexity of the mold design and movement used to manufacture the shell structure.

[0017] In some implementations, there is a gap between the bottom of the first wire groove and the third side surface.

[0018] By adopting the above technical solution, the first wire groove can provide a space for accommodating the transmission line, while the first wire groove does not penetrate the third surface and the fourth surface. This is beneficial to the overall strength of the second frame combined with the first frame, so that the shell structure can withstand greater pressure or load.

[0019] In some implementations, the length of the first wire groove extends along the length direction of the housing structure.

[0020] By adopting the above technical solution, the first wire duct can make the shell structure distribute the load or pressure more evenly, reduce the possibility of local stress concentration, and improve the bearing capacity and durability of the structure.

[0021] In some implementations, the first shell portion further includes a bottom plate, which is fixedly connected to the first frame, and the bottom plate is used to enclose an installation cavity.

[0022] By adopting the above technical solution, the bottom plate and the first frame together form an installation cavity, so as to facilitate the protection of the components in the installation cavity.

[0023] In some implementations, the second shell portion is made of plastic, and the first shell portion and the second shell portion are fixedly connected by an insert molding process.

[0024] By adopting the above technical solution, when the material of the second shell part is plastic, on the one hand, when the transmission line in the first wire slot is an antenna, the influence of the first frame and the components in the installation cavity on the transmission line can be reduced, and on the other hand, it is conducive to reducing production costs and lightweighting of the shell structure, and plastic has good corrosion resistance and electrical insulation. The use of the insert molding process is conducive to achieving the stability of the connection between the first shell part and the second shell part, improving the strength of the shell structure, and making the shell structure have a more complex shape and structure, and the insert molding process can provide greater design flexibility.

[0025] In some implementations, the first housing portion is made of metal or ceramic.

[0026] By adopting the above technical solution, the first housing part is made of metal material, which can effectively protect the internal components of the electronic device from external impact or pressure, and at the same time provide good structural support to prevent the mobile phone from deformation or damage, and has good thermal conductivity. The first housing part is made of ceramic material, which can provide good structural support to prevent the mobile phone from deformation.

[0027] In some implementations, the first wire groove is used to install a transmission line, wherein the transmission line electrically connects two electronic components of the electronic device.

[0028] By adopting the above solution, electrical connection between electronic components located at two different positions in the electronic device can be achieved, thereby ensuring the stability of the electrical connection.

[0029] A second aspect of the present application provides a method for manufacturing a housing structure, which is used to manufacture the housing structure in any of the above implementations, and includes:

[0030] Placing the first shell part as an insert on the rear mold of the shell structure manufacturing mold;

[0031] The insert of the shell structure manufacturing mold is brought into contact with the rear mold, wherein the first frame further has a first top surface connected to the first side surface and the second side surface respectively, and the insert abuts against the first top surface;

[0032] The slider of the shell structure manufacturing mold is moved along a first direction to contact the insert, so that the slider, the second side surface and the insert define an injection cavity for forming a second frame, wherein the first direction is non-parallel to the thickness direction of the shell structure, and the slider has a first protrusion in the form of a strip on one side facing the second side surface;

[0033] Injecting molding material into the molding cavity to form a second frame, and inserting the first protrusion into the second frame from the fourth side surface;

[0034] The sliding block is separated from the second frame so that the depression left by the first protrusion on the fourth side surface forms a first wire groove.

[0035] By adopting the above technical solution, the inserts of the mold no longer need to be designed with a thinner insertion structure, which reduces the impact and friction between the inserts, thereby reducing the possibility of insert breakage, increasing the service life of the inserts, and thus increasing the life of the mold, and also facilitating the manufacture of the shell structure.

[0036] In some implementations, the first direction is perpendicular to a thickness direction of the shell structure, and the first direction is also perpendicular to a length direction of the shell structure.

[0037] By adopting the above technical solution, it is easy to control the movement of the slider and reduce the difficulty of manufacturing the shell structure.

[0042] The movement direction of the slider is non-parallel to the length extension direction of the first protrusion, and the slider, the second side surface and the insert define an injection molding cavity for forming a second frame.

[0043] By adopting the above technical solution, the inserts of the mold no longer need to be designed with a thinner insertion structure, which reduces the impact and friction between the inserts, thereby reducing the possibility of insert breakage, increasing the service life of the inserts, and thus increasing the life of the mold, and also facilitating the manufacture of the shell structure.

[0044] In some implementations, the insert has a second molding surface, a third molding surface, and a fourth molding surface, the second molding surface is directly connected to the third molding surface, and the third molding surface is directly connected to the fourth molding surface;

[0045] The second molding surface is used to be opposite to the first top surface, and the fourth molding surface is used to construct the second top surface of the second frame.

[0046] By adopting the above technical solution, the second frame and the first frame have a more stable connection strength, and the overall rigidity and stability formed by combining the first frame and the second frame can be increased, which is beneficial to increase the load.

[0047] In some implementations, the insert is sandwiched between the back mold and the slider.

[0048] By adopting the above technical solution, the insert is clamped between the rear mold and the slider, which can make the movement of the shell structure manufacturing mold more stable and reliable, reduce production failures caused by loose or vibration parts of the shell structure manufacturing mold, thereby improving production efficiency and product quality.

[0049] In some implementations, the movement direction of the slider is perpendicular to the length extension direction of the first protrusion.

[0050] By adopting the above technical solution, it is easy to control the movement of the slider and reduce the difficulty of manufacturing the shell structure.

It can be understood that the local area in the length extension direction of the second frame 107 can also have a notch, which is conducive to reducing the space occupied by the second frame 107. Of course, the second frame 107 can also be in other forms, which is not limited by the embodiments of the present application.

[0078] It should be noted that, in some other embodiments, the middle frame can be an integrated structure with the back cover 103; the middle frame can also be an integrated structure with the device frame 102, which is not specifically limited in this application.

[0079] See also Figure 3 As shown, the first housing portion 104 further includes a bottom plate 110 , and the bottom plate 110 is used to enclose a mounting cavity 111 ; the first frame 106 is fixedly connected to the bottom plate 110 .

[0080] Exemplarily, the first frame 106 and the partial structure of the bottom plate 110 together enclose the installation cavity 111, so that the components in the installation cavity 111 can be protected; the first frame 106 is roughly quadrilateral, for example, rectangular.

The installation cavity, the first cavity 108 and the second cavity 109 are located on the same side of the bottom plate 110.

[0081] It should be noted that, in some other possible implementations, the bottom plate 110 may be omitted, or the bottom plate 110 may have the same area as the area enclosed by the first frame 106. In some other possible implementations, at least two of the installation cavity 111, the second cavity 109, and the first cavity 108 may be located on different sides of the bottom plate 110, which is not specifically limited in the present application. In other possible implementations, the second housing portion 105 may include an additional bottom plate 110, which is fixedly connected to the bottom plate 110.

[0082] See also Figure 3 As shown, the electronic device includes two electronic components, for example, the two electronic components are respectively a first electronic component and a second electronic component, and the first electronic component and the second electronic component are electrically connected through a transmission line 122. The first electronic component includes at least one of a first circuit board and a first electronic component; the second electronic component includes at least one of a first circuit board and a second electronic component; for example, the first electronic component may include a first circuit board 112, and the second sub-electronic component may include a second circuit board 113, and the first circuit board 112 and the second circuit board 113 are electrically connected through a transmission line 122. The first circuit board 112 may be a main board, and the display screen 101 is electrically connected to the first circuit board 112; the second circuit board 113 may be a small board. The number of transmission lines 122 between the first circuit board 112 and the second circuit board 113 may be one or more, for example, two or three, and different transmission lines 122 may have different functions, for example, one transmission line 122 is a cable, and one transmission line 122 is an antenna.

[0085] See also Figure 3 As shown, the length of the first long side portion 120 is less than the length of the second long side portion 121. Of course, in some other possible implementations, the length of the first long side portion 120 may also be greater than or equal to the length of the second long side portion 121.

The battery 114 is used to power the electrical components of the electronic device, such as the first circuit board 112, the display screen 101, and the second circuit board 113. Figure 3 The area occupied by the middle battery 114 is smaller than the area occupied by the mounting cavity 111, just to distinguish the mounting cavity 111 from the battery 114. The size of the battery 114 can be the same as the size of the mounting cavity 111 or slightly smaller than the size of the mounting cavity 111, and this application does not make any specific limitation.

[0087] Figure 4 is a structural schematic diagram of a device housing 10 of an electronic device in the related art; Figure 5 It is a state diagram of a mold manufacturing equipment housing 10 in the related art; Figure 4 and Figure 5As shown, the device housing 10, such as the middle frame, adopts a structure of a metal part 11 and a plastic part 12, and is generally manufactured by metal insert injection molding, wherein a mold slider 13, a mold back mold 14, and a mold insert 15 are mainly used to cooperate to achieve injection molding; a wiring groove 16 is generally designed on the device housing 10 for installing electrical connecting lines, such as wires or antennas, so as to achieve connection between electronic components or circuit boards located at different positions of the electronic equipment. The depth direction of the wiring groove 16 is the thickness direction of the device housing 10 (that is, the thickness direction of the electronic device). The wiring groove 16 designed in this way makes the bending resistance of the device housing 10 poor. In addition, when manufacturing the device housing 10, the mold insert 15 used to form the wiring groove 16 will be designed with a thinner insertion structure 17. The width d1 of the local position of the insertion structure 17 is about 0.48mm. There will be a gap d2 of 0.1mm between the insertion structure 17 and the metal part 11. During the injection molding process, the mold cavity is a high temperature and high pressure environment, so when the injection molding material is injected, When the quality is high, it will cause impact on the insertion structure 17, so that the insertion structure 17 is prone to metal fatigue. As the number of times the mold is used increases, the damage to the mold insert 15 is aggravated. In addition, when the mold is opened, the insertion structure 17 is squeezed by the plastic part 12, so that the insertion structure 17 will rub or collide with the metal part 11 of the device housing 10 as an insert. Moreover, when the mold is closed, the mold insert 15 is also prone to rub or collide with the metal part 11, so that the insertion structure 17 of the mold insert 15 is prone to breakage, which reduces the life of the mold insert 15. In addition, there is also a method of processing the wiring groove 16 on the inner side of the metal part 11, that is, the side facing the battery, by using a CNC machine tool. However, this method is also easy to wear the tool and leave scratches on the support plate 19 of the battery compartment 18. When the battery is assembled later, it is easy to cause the battery to be scratched, causing the battery to explode, which has safety hazards. Finally, the method of using a CNC machine tool also increases the manufacturing cost.

[0088] In order to solve the problems in the related art, the housing structure provided in the embodiment of the present application redesigns the position of the wiring trough in the related art. The housing structure provided in the embodiment of the present application is explained in detail below.

[0089] Figure 6 is a partial cross-sectional view of the housing structure provided in the embodiment of the present application; see Figure 6As shown, the first frame 106 has a first side surface 115 and a second side surface 116 opposite to each other, the first side surface 115 faces the installation cavity 111, and the second side surface 116 faces away from the installation cavity 111; the second frame 107 has a third side surface 117 and a fourth side surface 118 opposite to each other, the second frame 107 is located on the side where the second side surface 116 is located, the third side surface 117 is in contact with the second side surface 116, and a first wire groove 119 is provided on the fourth side surface 118. In this way, on the first aspect, by setting the first wire groove 119 on the fourth side surface 118, the insert 202 of the mold used to manufacture the shell structure can no longer be designed with a thinner insert structure. structure, which reduces the impact and friction between the inserts 202, thereby reducing the possibility of breakage of the insert 202, increasing the service life of the insert 202, thereby increasing the life of the mold, and facilitating the manufacture of the shell structure; secondly, the third side 117 is in contact with the second side 116, and the first wire groove 119 is located on the fourth side 118, which makes the second frame 107 equivalent to an I-beam structure, so that when the shell structure is subjected to a force parallel to the thickness direction of the shell structure, the bending resistance of the shell structure can be improved, and the shell structure can be applied to situations with strict space limits and high bending resistance requirements.

[0090] Exemplarily, the second frame 107 is fixedly connected to the first frame 106 , which can improve the connection strength between the two. The third side surface 117 is opposite to the second side surface 116 , thereby facilitating a close fit between the third side surface 117 and the second side surface 116 .

[0091] Combination Figure 6 As shown, the length of the first wire groove 119 extends along the length direction of the shell structure; thus, the first wire groove 119 can make the shell structure distribute the load or pressure more evenly, reduce the possibility of local stress concentration, and improve the bearing capacity and durability of the structure. Exemplarily, the first wire groove 119 can be located on a second long side 121 of the second frame 107, and the length of the first wire groove 119 extends along the length direction of the second long side 121. It should be noted that in some other possible embodiments, the first wire groove 119 can also be provided on the structure of the second frame 107 parallel to the width direction of the shell structure.

[0092] See also Figure 6As shown, the first long side 120 is fixedly connected to the second long side 121. The portion of the second side 116 on the first long side 120 contacts the portion of the third side 117 on the second long side 121. The notch of the first wire slot 119 faces away from the third side 117; the cross section of the first wire slot 119 is roughly U-shaped; the cross section of the first wire slot is perpendicular to the length direction of the shell structure. The groove depth of the first wire slot 119 can be designed as needed. When only one transmission line 122 is accommodated, its depth can be substantially the same as the diameter of the transmission line 122, or slightly larger than the diameter of the transmission line 122; when multiple transmission lines 122 need to be accommodated, the groove depth can be the sum of the diameters of the multiple transmission lines 122. In addition, for the adopted transmission line 122, its cross section can be circular or rectangular, etc., and can be specifically designed as needed. When the cross section of the transmission line 122 is rectangular, the groove depth of the first wire slot 119 can be not less than the length of the rectangle of the cross section of the transmission line 122. The matching mode between the transmission line 122 and the first wire groove 119 can be two clearance matches or interference fits; the fixing mode between the transmission line 122 and the first wire groove 119 can be designed according to needs, such as a snap-fit ​​connection, or a glue-fixed connection. Of course, the two can also be not fixed; this application does not make specific limitations.

[0093] See also Figure 6 As shown, the number of the first wire groove 119 is one. Of course, it is understandable that two or three first wire grooves 119 can be set in the thickness direction of the shell structure as needed, so that the multiple first wire grooves 119 are isolated from each other to reduce the influence of the transmission lines 122 in the two adjacent first wire grooves 119. It should be noted that in some other possible implementations, when some sensors are installed on the side of the electronic device in the thickness direction, for example, such as a touch sensor, a temperature sensor, a humidity sensor or an air pressure sensor, the transmission line 122 can also be used to connect them to realize the connection between them and the mainboard of the electronic device.

[0094] Figure 7 is a state diagram of the transmission line 122 installed in the first line slot 119 in the embodiment of the present application; see Figure 7 As shown, the transmission line 122 is installed in the first wire slot 119. In this way, the transmission line 122 in the first wire slot 119 and the components (such as the battery 114) in the installation cavity 111 can be isolated from each other, which is beneficial to reduce the influence between them.

[0095] Combination Figure 6 and Figure 7As shown, the first frame 106 also includes a first top surface 123, and the second side surface 116 includes a first sub-surface 124 and a second sub-surface 125. The second sub-surface 125 and the first top surface 123 are respectively connected to the first sub-surface 124, and the first sub-surface 124 and the second sub-surface 125 are non-parallel to each other. The second sub-surface 125 and the first top surface 123 have a height difference in the thickness direction of the shell structure; the first sub-surface 124 and the second sub-surface 125 are respectively in contact with the third side surface 117, so that the second sub-surface 125 and the first top surface 123 have a height difference, so that the third side surface 117 is respectively in contact with the first sub-surface 124 and the second sub-surface 125, and the contact area between the third side surface 117 and the second side surface 116 is increased, thereby improving the strength of the combination between the first frame 106 and the second frame 107, and can increase the overall rigidity and stability formed by the combination of the first frame 106 and the second frame 107, which is beneficial to increase the load.

[0096] Exemplarily, the first side surface 115 and the second side surface 116 are connected to the first top surface 123 respectively; the first top surface 123 and the second sub-surface 125 can be arranged in parallel, and the first sub-surface 124 and the second sub-surface 125 are directly connected. It should be noted that the second side surface 116 mainly includes the first sub-surface 124 and the second sub-surface 125, and of course can also include other sub-surfaces, that is, the second side surface 116 can include more than two sub-surfaces, for example, the second side surface 116 can also include a third sub-surface, a fourth sub-surface, a fifth sub-surface and a seventh sub-surface connected in sequence, wherein the third sub-surface is connected to the second sub-surface 125.

[0097] Combination Figure 6 and Figure 7 As shown, the second frame 107 has a second top surface 126, the third side surface 117 and the fourth side surface 118 are respectively connected to the second top surface 126, and there is a height difference between the first top surface 123 and the second top surface 126. It should be noted that the first top surface 123 and the second top surface 126 can also be set to be flush as needed.

[0098] Combination Figure 6 and Figure 7 As shown, the groove depth direction of the first wire groove 119 is not parallel to the thickness direction of the shell structure. This is conducive to enhancing the strength and stability of the shell structure, and the existence of the first wire groove 119 can disperse stress to a certain extent and improve the compressive resistance of the shell structure.

[0099] Exemplarily, the angle between the groove depth direction of the first wire groove 119 and the thickness direction of the shell structure is a right angle or an acute angle. This can provide better structural support and stability, thereby enhancing the overall strength of the shell structure, thereby improving the ability of the shell structure to resist external pressure or impact load; and when the angle between the groove depth direction of the first wire groove 119 and the thickness direction of the shell structure is a right angle, the second long side 121 is in the form of an I-beam, so that at least part of the structure of the second frame 107 is in the form of an I-beam, thereby improving the bending resistance of the shell structure; in addition, it is also conducive to reducing the complexity of the mold design and movement used to manufacture the shell structure.

[0100] Combination Figure 6 and Figure 7 As shown, there is a gap between the bottom of the first wire groove 119 and the third side surface 117, so that while the first wire groove 119 can provide a space for accommodating the transmission line 122, the first wire groove 119 does not penetrate the third surface and the fourth surface, which is beneficial to the overall strength of the second frame 107 combined with the first frame 106, so that the shell structure can withstand greater pressure or load, which is beneficial to reduce the possibility of damage to the first protrusion on the slider of the mold. Exemplarily, the groove of the first wire groove 119 is still a structural part of the second frame 107.

[0101] It should be noted that, in some other possible embodiments, the bottom of the first wire groove 119 may also be formed by the second side 116 of the first frame 106, that is, at least a portion of the first wire groove 119 is located in the width direction of the shell structure and passes through the fourth side 118 and the third side 117 of the second frame 107.

[0102] Figure 8 is a simplified schematic diagram of the transmission line installed in the first line slot 119 in the embodiment of the present application; Figure 7 and Figure 8 As shown, one end of the transmission line 122 is connected to the first circuit board 112, and the other end of the transmission line 122 is connected to the second circuit board 113. The length of the first wire groove 119 is greater than or equal to the length of the first frame 106 in the length direction of the housing structure. Exemplarily, the length of the first wire groove 119 is greater than the length of the first long side 120.

[0103] A wire-passing structure 127 is also provided on the second frame 107, so that the transmission line 122 can pass through the wire-passing structure 127, so that the transmission line 122 can pass from the third side surface 117 of the second frame 107 to the fourth side surface 118, and then the transmission line 122 is installed in the first wire groove 119. Exemplarily, there are two wire-passing structures 127; the transmission line 122 has a buried wire segment and a connecting segment, the buried wire segment is located in the first wire groove 119, and the length of the buried wire segment extends along the length of the first wire groove 119. The two ends of the buried wire segment in the length direction are respectively connected to a connecting segment, and the first circuit board 112 and the second circuit board 113 are electrically connected through two different connecting segments; and the connecting segment passes through the wire-passing structure 127.

[0104] like Figure 8 As shown, in some embodiments, the wire-passing structure 127 may be a slot structure, the depth direction of the slot structure is parallel to the thickness direction of the shell structure, and the slot structure can facilitate the installation of the transmission line. It should be noted that in other embodiments, the wire-passing structure 127 may also be a through hole, which passes through the third side surface 117 and the fourth side surface 118, and the through hole can ensure the structural strength of the second frame 107.

[0105] It is understandable that in some other possible implementations, the transmission line 122 can also be installed in the first wire groove 119 in the form of a jumper, that is, no wire passing structure 127 is set on the second frame 107, and the transmission line 122 bypasses the second top surface 126.

[0106] It should be noted that in some possible embodiments, when the length of the first wire groove 119 is smaller than the length of the first frame 106 in the length direction of the shell structure, a wire passing structure 127 is also required to be provided on the first frame 106 to facilitate the transmission line 122 to pass through the first frame 106 .

[0107] In some embodiments, the second housing portion 105 is made of plastic, and the first housing portion 104 and the second housing portion 105 are fixedly connected by an insert molding process. In this way, when the second housing portion 105 is made of plastic, on the one hand, when the transmission line 122 in the first wire slot 119 is an antenna, the influence of the first frame 106 and the components in the mounting cavity 111 on the transmission line 122 can be reduced. On the other hand, it is conducive to reducing production costs and lightweighting of the housing structure, and the plastic has good corrosion resistance and electrical insulation. The use of the insert molding process is conducive to achieving the stability of the connection between the first housing portion 104 and the second housing portion 105, improving the strength of the housing structure, and can make the housing structure have a more complex shape and structure. In addition, the insert molding process can provide greater design flexibility. Exemplarily, the second housing portion 105 is formed by injection molding.

[0108] In some embodiments, the material of the first housing portion 104 is metal. In this way, the first housing portion 104 is made of metal material, which can effectively protect the internal components of the electronic device from external impact or pressure, while providing good structural support to prevent the mobile phone from deformation or damage, and has good thermal conductivity. Exemplarily, the metal is stainless steel, aluminum alloy or titanium. It should be noted that in some other possible embodiments, the material of the first housing portion 104 can also be ceramic.

[0109] Fig. 9 It is a partial structural schematic diagram of the shell structure manufacturing mold provided in the embodiment of the present application; Figure 7 and Fig. 9 As shown, in one or more embodiments, the present application also provides a shell structure manufacturing mold for manufacturing the shell structure in any embodiment of the present application, and the shell structure manufacturing mold includes: a rear mold 201, an insert 202 and a slider 203; the rear mold 201 is used to carry the insert, the insert is the first shell part 104, and the first frame 106 has a first top surface 123; the insert 202 can contact with the rear mold 201; the slider 203 can contact with the insert 202, and the slider 203 has a first molding surface 205 for constructing the fourth side 118 and a first protrusion 204 for constructing the first wire groove 119; wherein the movement direction of the slider 203 is non-parallel to the length extension direction of the first protrusion 204, and the slider 203, the second side 116 and the insert 202 define an injection cavity for forming the second frame 107. In this way, the insert 202 does not need to be designed with a thinner insertion structure, which reduces the collision and friction between the inserts 202, thereby reducing the possibility of the insert 202 breaking, increasing the service life of the insert 202, and thus increasing the life of the mold, and facilitating the manufacture of the shell structure; the slider 203 forming the first wire groove 119 is designed on the side where the fourth side 118 of the second frame 107 of the plastic structure is located, thereby reducing the influence of the first frame 106 on the slider 203, and also helping to increase the life of the mold. In addition, the first wire groove 119 is formed by setting the first protrusion 204 on the slider 203, which also improves the bending resistance of the shell structure.

[0110] Exemplarily, the first housing part 104 as an insert can be detachably fixed to the rear mold 201 by means of negative pressure; the housing structure manufacturing mold also includes a front mold (not shown), and the front mold, the rear mold 201, the insert 202 and the slider 203 cooperate together to form a cavity, so as to inject the injection material into the cavity to form the second housing part 105. For the housing structure manufacturing mold, its mold opening direction and mold closing direction are parallel to the thickness direction of the housing structure, and the movement direction of the insert 202 relative to the rear mold 201 is parallel to the thickness direction of the housing structure. It should be noted that the slider 203 can also be called a slider; in addition, the housing structure manufacturing mold is not limited to the manufacture of housing structures of electronic devices, but can also be applied to the manufacture of other structures with limited use space, strength requirements and grooves.

[0111] Combination Figure 7 and Fig. 9 As shown, the insert 202 has a second molding surface 206, a third molding surface 207 and a fourth molding surface 208, the second molding surface 206 is directly connected to the third molding surface 207, and the third molding surface 207 is directly connected to the fourth molding surface 208; the second molding surface 206 is used to be opposite to the first top surface 123, and the fourth molding surface 208 is used to construct the second top surface 126 of the second frame 107. In this way, the second frame 107 and the first frame 106 have a relatively stable connection strength, and the rigidity and stability of the whole formed by the combination of the first frame 106 and the second frame 107 can be increased, so as to help increase the load. It should be noted that when the second molding surface 206 is opposite to the first top surface 123, the second molding surface 206 can be in contact with the first top surface 123, or there can be a gap between the second molding surface 206 and the first top surface 123, which is not specifically limited in this application.

[0112] Exemplarily, the third molding surface 207 is used to contact the second side surface 116, so that the quality of the formation of the second frame 107 can be ensured.

[0113] Combination Figure 7 and Fig. 9 As shown, the insert 202 is clamped between the rear mold 201 and the slider 203, so that the insert 202 can make the action of the shell structure manufacturing mold more stable and reliable, reduce the production failure caused by the looseness or vibration of the parts of the shell structure manufacturing mold, thereby improving the production efficiency and product quality. For example, when closing the mold, the insert is first adsorbed on the rear mold 201, then the insert 202 is moved to a predetermined position, and finally the slider 203 is moved to a predetermined position.

[0114] In some embodiments, the movement direction of the slider 203 is perpendicular to the length extension direction of the first protrusion 204. This makes it easier to control the movement of the slider 203 and reduces the difficulty of manufacturing the shell structure. Exemplarily, the movement direction of the slider 203 is parallel to the width direction of the shell structure, that is, the movement direction of the slider 203 is perpendicular to the mold closing direction of the shell structure manufacturing mold. Exemplarily, after the first shell structure is adsorbed on the rear mold 201, the length extension direction of the first protrusion 204 is parallel to the length direction of the shell structure. It can be understood that in some possible embodiments, the movement direction of the slider 203 can also be designed to have an angle with the thickness direction of the shell.

[0115] It should be noted that the rear mold 201 can be a fixed mold, and the front mold can be a movable mold; or, the rear mold 201 can be a movable mold, and the front mold can be a fixed mold; this application does not make any specific limitation.

[0116] Fig.10 is a simplified schematic diagram of a slider provided in an embodiment of the present application, see Fig.10 As shown, in some possible embodiments, a second protrusion 209 is further provided on the slider, and the second protrusion 209 is used to construct a wire-passing structure 127 on the second frame 107, so that the transmission line 122 passes through the third side surface 117 and the fourth side surface 118 of the second frame 107. The second protrusion 209 is located at both ends of the length direction of the first protrusion 204. The length of the second protrusion 209 is less than half of the length of the first protrusion 204. Exemplarily, the length of the second protrusion 209 in the length direction of the housing structure is greater than or equal to the diameter of the transmission line 122, so that part of the structure of the transmission line 122 can be located in the wire-passing structure 127.

[0117] It should be noted that, in some other possible implementations, the second protrusion 209 may also be provided on the insert 202 .

[0118] Fig.11 It is a state diagram of the shell structure manufacturing mold manufacturing the shell structure provided in the embodiment of the present application; Fig.11 The figure shows the partial structure of the shell structure manufacturing mold and the partial structure of the shell structure. Figure 7 , Fig. 9 , Fig.10 and Fig.11 As shown, in one or more embodiments, the present application also provides a shell structure manufacturing method for manufacturing the shell structure in any embodiment of the present application. The shell structure manufacturing method can adopt the shell structure manufacturing mold in any embodiment of the present application.

[0119] In the embodiment of the present application, the shell structure manufacturing method includes:

[0120] The first housing part 104 as an insert is placed on the rear mold 201 of the housing structure manufacturing mold;

[0121] The insert 202 of the shell structure manufacturing mold is brought into contact with the rear mold 201, wherein the first frame 106 further has a first top surface 123 connected to the first side surface 115 and the second side surface 116 respectively, and the insert 202 abuts against the first top surface 123;

[0122] The slider 203 of the shell structure manufacturing mold is moved along the first direction to contact the insert 202, so that the slider 203, the second side surface 116 and the insert 202 define an injection cavity for forming the second frame 107, wherein the first direction is non-parallel to the thickness direction of the shell structure, and the slider 203 has a first protrusion 204 in the form of a strip on one side facing the second side surface 116;

[0123] Injecting molding material into the molding cavity to form the second frame 107, and inserting the first protrusion 204 into the second frame 107 from the fourth side surface 118;

[0124] The slider 203 is separated from the second frame 107 , so that the depression left by the first protrusion 204 on the fourth side surface 118 forms a first wire groove 119 .

[0125] The shell structure manufacturing method in the embodiment of the present application no longer needs to design an insert structure with a thinner thickness for the insert 202, which reduces the impact and friction between the inserts 202, thereby reducing the possibility of breakage of the insert 202, increasing the service life of the insert 202, and further increasing the life of the mold, and also facilitating the manufacture of the shell structure.

[0126] In some embodiments, the method of placing the first shell part 104 as an insert on the rear mold 201 of the shell structure manufacturing mold includes: using negative pressure to absorb the first shell part 104 on the rear mold 201.

[0127] In some embodiments, a method of bringing an insert 202 of a shell structure manufacturing mold into contact with a rear mold 201 includes: moving the insert 202 along a set direction to contact the rear mold 201, wherein the set direction is parallel to the thickness direction of the shell structure.

[0128] In some embodiments, before the method of injecting the injection molding material into the injection molding cavity, the method further includes: joining the rear mold 201 with the front mold to achieve mold closing and form a mold cavity; and the injection molding cavity is a part of the mold cavity, that is, the mold cavity includes the injection molding cavity. Injecting the injection molding material into the mold cavity also achieves the injection molding material being injected into the injection molding cavity.

[0129] In some embodiments, the first direction is perpendicular to the thickness direction of the shell structure, and the first direction is also perpendicular to the length direction of the shell structure; this makes it easier to control the movement of the slider 203 and reduces the difficulty of manufacturing the shell structure. Exemplarily, after the slider 203 contacts the insert 202, the first protrusion 204 is suspended, so that the first protrusion 204 is not in contact with the insert 202 or the first shell part 104, such as the first frame 106, except for being connected to the slider 203, so that the first protrusion 204 does not collide with other components, thereby protecting the slider 203 and the first protrusion 204. It should be noted that in some other possible embodiments, the first protrusion 204 used to form the first wire groove 119 is not limited to being set on the slider 203, but can also be set on other components of the mold, as long as it does not contact the insert during its movement.

[0130] In some embodiments, the method of separating the slider 203 from the second frame 107 further includes: forming a wire-passing structure 127 in the depression left by the second protrusion 209 in the second frame 107 ; and the wire-passing structure 127 is connected to the first wire groove 119 .

[0131] After the injection molding material is injected into the cavity, the second shell part 105 is formed after the injection molding material is cooled, and the second shell part 105 and the first shell part 104 together form a shell structure; finally, the slider 203 is separated from the insert 202, the insert 202 is separated from the rear mold 201, the front mold is separated from the rear mold 201, and the shell structure is ejected from the rear mold 201.

[0132] In the description of the specification of the present application, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0133] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
