Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and in particular relates to electronic equipment and an assembly method thereof. Background Art

[0002] As electronic devices evolve, users have higher and higher requirements for the waterproof performance of electronic devices. For example, electronic devices usually have buttons on their exterior surfaces, and sealing structures are usually set on the buttons. However, after long-term use, the sealing structure may have local uneven wear, resulting in sealing failure. Summary of the invention

[0003] In view of this, a first aspect of the present application provides an electronic device, the electronic device comprising:

[0004] A shell body having a receiving groove, and one side of the shell body having a through hole communicating with the receiving groove;

[0005] A key switch assembly is disposed in the receiving groove;

[0006] A button, comprising a pressing portion and a first transmission portion, wherein at least a portion of the pressing portion protrudes from the housing, and the first transmission portion passes through the through hole; and

[0007] A sealing member is disposed in the through hole, the sealing member comprises a second transmission part and a sealing part bent and connected to the second transmission part, the second transmission part and the sealing part are surrounded to form a sealed space and sleeved on the first transmission part, the sealing part is sealed and connected to the hole wall of the through hole, and the second transmission part is disposed between the first transmission part and the key switch assembly;

[0008] When the pressing portion is pressed, the pressing portion can drive the first transmission portion to move in a direction close to the key switch assembly, so that the first transmission portion abuts against the second transmission portion, and further the second transmission portion abuts against the key switch assembly.

[0009] The electronic device provided in the first aspect of the present application is provided with a sealing member on the basis of a housing, a key switch assembly, and a key. The sealing member can be arranged in a through hole, and the sealing member is composed of a second transmission part and a sealing member, and the second transmission part and the sealing member can be surrounded to form a sealed space, and the sealing member is sleeved outside the first transmission part of the key. In other words, the first transmission part is arranged in the sealed space, and at this time the sealing member can wrap up the first transmission part, and the second transmission part is arranged between the first transmission part and the key switch assembly, so that water and other impurities will not pass through the sealing member. At the same time, the sealing member can be sealed and connected with the hole wall of the through hole, so that water and other impurities will not pass through between the sealing member and the hole wall of the through hole, thereby realizing the waterproof function of the electronic device.

[0010] When the key is pressed, the pressing part drives the first transmission part to move and abut against the second transmission part, and then the second transmission part abuts against the key switch assembly, thereby realizing the corresponding function. Since the sealing interface of the seal, that is, the surface where the sealing part contacts the hole wall of the through hole, does not participate in the key activity, only the second transmission part of the non-sealing interface participates in the activity, thereby avoiding the wear of the seal and thus avoiding the degradation of the sealing quality of the key position after long-term use.

DETAILED DESCRIPTION

[0058] The following are preferred implementations of the present application. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications are also considered to be within the scope of protection of the present application.

[0059] Before introducing the technical solutions provided by this application, the technical problems in the related technologies are introduced in detail.

[0060] With the evolution of electronic devices such as mobile phones, users have higher and higher requirements for the waterproof performance of mobile phones. For example, the waterproof level of mobile phones has gradually increased from IPX6 to IPX8, and there are more and more IPX8 waterproof models. The appearance of electronic devices such as mobile phones is provided with buttons, such as the front buttons of the mobile phone, or side buttons on the side, and various functions can be achieved by pressing the buttons. This application and the following text are schematically described with the waterproof structure of the side buttons. The sealing ring assembled and sleeved on the transmission part of the button can be interference fit with the wall of the through hole on the shell to prevent liquid from entering the inside from the outside of the whole machine, thereby realizing the waterproofing of the side buttons.

[0061] The disadvantage of the current side button waterproofing solution is that the sealing interface, i.e. the contact surface between the sealing ring and the through-hole wall, moves as the user triggers the button. Since the position where the user presses the button is random, after long-term use, the polymer sealing ring may have localized uneven wear, resulting in sealing failure. In addition, when the phone is pressed underwater, there is a pressure difference between the inside and outside of the sealing interface, and there is a risk of liquid ingress during the movement of the button. For example, when the user presses the button to one side, the button will also deflect to a certain extent while moving, resulting in a decrease in the sealing performance on one side, and external water may enter the phone.

[0062] Based on this, in order to solve the above problems, this application provides an electronic device. Please refer to Figure 1-Figure 6 , Figure 1 It is a schematic diagram of the three-dimensional structure of an electronic device in one embodiment of the present application. Figure 2 for Figure 1 A schematic cross-sectional view of an electronic device is shown. Figure 3 for Figure 1 The illustrated electronic device includes a partial three-dimensional structural schematic diagram of buttons. Figure 4 for Figure 3 An exploded view of the electronic device is shown. Figure 5 for Figure 3 A schematic cross-sectional view of an electronic device is shown. Figure 6 for Figure 5 A partially enlarged cross-sectional schematic diagram of an electronic device is shown.

[0063] The electronic device 1 provided in this embodiment includes a housing 10, a key switch assembly 40, a key 30, and a sealing member 50. The housing 10 has a receiving groove 100, and one side of the housing 10 has a through hole 101 connected to the receiving groove 100, and the key switch assembly 40 is arranged in the receiving groove 100. The key 30 includes a pressing portion 31 and a first transmission portion 32, at least part of the pressing portion 31 protrudes from the housing 10, and the first transmission portion 32 passes through the through hole 101. The sealing member 50 is arranged in the through hole 101, and the sealing member 50 includes a second transmission portion 51 and a sealing portion 52 bent and connected to the second transmission portion 51, the second transmission portion 51 and the sealing portion 52 are surrounded to form a sealed space 500 and are sleeved on the first transmission portion 32, the sealing portion 52 is sealed and connected to the hole wall of the through hole 101, and the second transmission portion 51 is arranged between the first transmission portion 32 and the key switch assembly 40. When the pressing portion 31 is pressed, the pressing portion 31 can drive the first transmission portion 32 to move in a direction close to the key switch assembly 40 , so that the first transmission portion 32 abuts against the second transmission portion 51 , and further the second transmission portion 51 abuts against the key switch assembly 40 .

[0064] The electronic device 1 provided in this embodiment includes but is not limited to mobile terminals such as mobile phones, tablet computers, laptop computers, PDAs, personal computers (PCs), personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc., as well as fixed terminals such as digital TVs and desktop computers. This embodiment only uses a mobile phone as an example for schematic illustration.

[0065] The electronic device 1 generally includes a middle frame, a battery cover 20, a display module 21 and other structures. One side of the middle frame is used to install the display module 21, and the other side is used to install the battery cover 20. The middle frame includes a bottom wall and a side wall, and a key switch assembly 40 and a key 30 are generally provided on the side wall. Therefore, the middle frame is the housing 10 of this embodiment. Since the size of the middle frame is relatively large, this embodiment and the following description only schematically illustrate the partial structure of the key switch assembly 40 and the key 30 installed on the middle frame.

[0066] The housing 10 may be provided with a receiving groove 100 on one side facing the battery cover 20, so as to facilitate the subsequent receiving of the key switch assembly 40. The outer surface of the housing 10 may be provided with a through hole 101 connected to the receiving groove 100, so as to facilitate the subsequent installation of the key 30. The key switch assembly 40 may be electrically connected to the controller in the electronic device 1. When the key switch assembly 40 is pressed, it can send a corresponding signal to the controller, so that the controller performs various operations to realize various functions, such as volume control, power screen, photo taking and the like.

[0067] The key 30 includes a pressing portion 31 and a first transmission portion 32, wherein at least a portion of the pressing portion 31 protrudes from the housing 10 so that it can be pressed by a user or other components. The first transmission portion 32 is provided with a through hole 101 and is close to the key switch assembly 40, so that when the pressing portion 31 is pressed, the pressing portion 31 can drive the first transmission portion 32 to transfer the pressing force to the key switch assembly 40 to achieve various functions. Optionally, a key conductive base 33 is provided at the end of the first transmission portion 32, and the material of the key conductive base 33 is relatively soft, which can be better matched with the second transmission portion 51 of the seal 50 later, so as to avoid the first transmission portion 32 damaging the seal 50 after long-term use.

[0068] Optionally, the electronic device 1 may further include a key latch 60. The housing 10 may further include a latch hole 102 on a surface adjacent to the surface where the through hole 101 is provided, such as a surface where the receiving groove 100 is provided. The latch hole 102 may be connected to the through hole 101. The key latch 60 may be installed in the latch hole 102 and cooperate with the pressing portion 31 to limit the key 30 and prevent the key 30 from falling from the through hole 101.

[0069] In the related art, a circle of sealing ring is arranged outside the first transmission part 32, and the sealing ring and the hole wall of the through hole 101 are interference fit to achieve sealing, but when the key 30 moves, the sealing interface of the key 30 will also move, so the seal will fail due to wear. The present embodiment also provides a sealing member 50, but a sealing member 50 of a new structure is provided. The sealing member 50 can be arranged in the through hole 101 to facilitate the cooperation with the key 30 and the through hole 101. The sealing member 50 is composed of a second transmission part 51 and a sealing member 52 bent and connected to the periphery of the second transmission part 51. The sealing member 50 is U-shaped as a whole. The second transmission part 51 and the sealing member 52 can be surrounded to form a sealed space 500. The sealing member 50 is sleeved outside the first transmission part 32 of the key 30. In other words, the first transmission part 32 is arranged in the sealed space 500, and the seal 50 can wrap the first transmission part 32. The second transmission part 51 is arranged between the first transmission part 32 and the key switch assembly 40. Therefore, by using the seal 50 with a U-shaped structure, water and other impurities will not pass through the seal 50. The second transmission part 51 is responsible for slightly deforming when the user presses the key 30 to transfer the force and displacement on the key 30 to the key switch assembly 40 to realize the function of the key 30. At the same time, the seal 52 can be sealed and connected with the hole wall of the through hole 101, so that water and other impurities will not pass through between the seal 50 and the hole wall of the through hole 101, thereby sealing the through hole 101 at all places. When external water enters the through hole 101, it will only be set in the sealed space 500 of the seal 50, realizing the waterproof function of the key 30.

[0070] Optionally, the material of the seal 50 includes but is not limited to silicone, soft rubber, etc., which facilitates the sealing connection between the sealing part 52 and the hole wall of the through hole 101, and at the same time facilitates the second transmission part 51 to deform to a certain extent under the drive of the first transmission part 32, thereby supporting the key switch assembly 40.

[0071] Optionally, the sealing member 50 may be formed by a molding method including but not limited to mold molding, injection molding, extrusion molding, and the like.

[0072] When the button 30 is pressed, that is, when the pressing part 31 is pressed, the pressing part 31 can drive the first transmission part 32 to move, so that the button 30 as a whole moves toward the direction close to the button 30 component. At this time, the first transmission part 32 of the button 30 can abut against the second transmission part 51, and under the action of the pressing force, the second transmission part 51 will also move toward the direction close to the button 30 component, thereby making the second transmission part 51 abut against and press the button switch component 40, thereby realizing the corresponding function.

[0073] It can be seen from the above process that when the key 30 is pressed, the first transmission part 32 will only drive the second transmission part 51 to move, and the sealing part 52 that is sealed and connected to the hole wall of the through hole 101 will not move. In other words, since the sealing interface of the sealing member 50, that is, the surface where the sealing member 52 contacts the hole wall of the through hole 101, does not participate in the movement of the key 30, only the second transmission part 51 that is not the sealing interface participates in the movement, thereby avoiding the wear of the sealing member 50 and thus avoiding the reduction of the sealing quality of the key 30 position after long-term use, that is, the sealing member 52 and the hole wall of the through hole 101 will not move relative to each other, resulting in a reduced wear rate at the seal and improved sealing performance. At the same time, in the scenario of operating the button 30 underwater, since the sealing part 52 and the wall of the through hole 101 do not move relative to each other, even if the position of pressing the button 30 is biased to one side so that the button 30 produces a certain deflection while moving, it will not affect the sealing performance of the sealing part 52 and the wall of the through hole 101, thereby reducing the risk of liquid entering the button 30 position, expanding the use of the electronic device 1 to underwater scenarios, and enriching the use scenarios of the electronic device 1.

[0074] In summary, the electronic device 1 provided in this embodiment, by designing the structure of the seal 50, designs the sealing interface to a non-active position of the key 30, avoids the wear of the sealing interface, reduces the risk of liquid crossing the sealing interface when the key 30 is operated underwater, and improves the sealing performance. In addition, by sleeve-arranging the seal 50 on the first transmission part 32 of the key 30, this embodiment can also reduce the space occupied by the key 30 structure in the thickness direction of the electronic device 1 compared to the related art, which is conducive to the thinness of the electronic device 1.

[0075] Optionally, when the key 30 is not pressed, the first transmission part 32 may abut against the second transmission part 51, and the second transmission part 51 may abut against the key switch assembly 40, and at this time, the key 30 can press the key switch assembly 40 as soon as it moves. Of course, in other embodiments, there may be a certain gap between the first transmission part 32 and the second transmission part 51, and / or between the second transmission part 51 and the key switch assembly 40, and at this time, the key 30 needs to move a certain distance before it can press the key switch assembly 40.

[0076] Please refer to Figure 6-Figure 8 , Figure 7 It is a schematic diagram of the three-dimensional structure of a sealing member in one embodiment of the present application. Figure 8 for Figure 7Schematic diagram of the three-dimensional structure of the seal from another perspective shown. In this embodiment, a sealing rib 520 is provided on the outer peripheral side of the sealing portion 52, and the sealing portion 52 and the hole wall of the through hole 101 are interference-fitted through the sealing rib 520. In this embodiment, an annular sealing rib 520 can be provided on the outer peripheral side of the sealing portion 52, and the sealing rib 520 can include one or more along the axial direction of the seal 50. Therefore, the sealing portion 52 and the hole wall of the through hole 101 can be interference-fitted through the sealing rib 520, so that the sealing portion 52 is sealed and connected to the hole wall of the through hole 101 to achieve a sealing function.

[0077] Please refer to Figure 7-Figure 11 , Fig. 9 It is a schematic diagram of a partial three-dimensional structure of a shell in one embodiment of the present application. Fig.10 It is a schematic diagram of the three-dimensional structure of the shell and the sealing member when they cooperate in one embodiment of the present application. Fig.11 for Figure 6 The schematic cross-sectional view of the button, housing, and seal when they are matched is shown. In this embodiment, the housing 10 has a receiving groove 103 connected to the through hole 101 on one side, and the receiving groove 103 is used to receive part of the pressing portion 31. The seal 50 also includes a first lug 53, which is bent and connected to an end of the sealing portion 52 away from the second transmission portion 51, and the first lug 53 is fixed to the bottom wall of the receiving groove 103.

[0078] In this embodiment, a receiving groove 103 may be provided on the surface where the through hole 101 is provided, i.e., the appearance surface of the housing 10. The through hole 101 is connected to and penetrates the bottom wall of the receiving groove 103. The receiving groove 103 may be used to accommodate part of the pressing portion 31, so that only the end of the pressing portion 31 protrudes from the housing 10 for the user to press, thereby avoiding excessive pressure on the pressing portion 31. On the basis of the overall U-shaped sealing member 50, a first lug 53 bent outwardly and connected may be provided at the first end of the sealing member 52 away from the second transmission member 51. In other words, the lower end of the sealing member 52 is provided with the second transmission member 51 bent inwardly and connected, and the upper end of the sealing member 52 is provided with the first lug 53 bent outwardly and connected. At this time, the first lug 53 may also be understood as the skirt of the sealing member 50. In this embodiment, the sealing portion 52 and the second transmission portion 51 can be arranged in the through hole 101 of the bottom wall of the accommodating groove 103, and the first lug 53 is fixed on the bottom wall of the accommodating groove 103, thereby improving the fixing effect of the sealing member 50, preventing the sealing member 50 from falling off when driven by the key 30, and allowing the sealing member 50 to be stably arranged in the through hole 101.

[0079] Optionally, a first adhesive member 54 is provided on a surface of the first lug 53 on a side close to the key switch assembly 40 , and the first lug 53 can be bonded to the bottom wall of the accommodating groove 103 through the first adhesive member 54 .

[0080] In this embodiment, the bottom wall of the receiving groove 103 has a recessed groove 104 connected to the through hole 101, and at least part of the first lug 53 is disposed in the recessed groove 104. On the basis of providing the receiving groove 103, a recessed groove 104 connected to the through hole 101 can also be provided on the bottom wall of the receiving groove 103, so that when the sealing member 50 is installed, at least part of the first lug 53 can be disposed in the recessed groove 104, thereby reducing the protruding size of the first lug 53 and reducing the size of the whole machine. In addition, the recessed groove 104 can also facilitate positioning and limiting when the sealing member 50 is installed, so as to facilitate the installation of the sealing member 50.

[0081] Please refer to Figure 6 , Figure 11-13 , Fig.12 It is a schematic diagram of the three-dimensional structure when the sleeve and the sealing element cooperate with each other in one embodiment of the present application. Fig.13 for Fig.12 In this embodiment, the electronic device 1 further comprises a sleeve 70, which is arranged in the sealed space 500 and sleeved on the peripheral side of the first transmission part 32, the first transmission part 32 passes through the sleeve 70 and can abut against the second transmission part 51, and the side of the sleeve 70 facing away from the first transmission part 32 abuts against the sealing part 52.

[0082] In addition to the above components, the electronic device 1 may also include a sleeve 70, which is made of hard plastic or metal materials. In other words, the sleeve 70 is relatively hard and the seal 50 is relatively soft. The sleeve 70 is a tubular structure with a hollow interior, that is, the sleeve 70 has a hole 700 that penetrates along its axial direction. The sleeve 70 can be arranged in the sealing space 500 of the seal 50, and the sleeve 70 is also sleeved on the outer peripheral side of the first transmission. In other words, the first transmission part 32 can pass through the sleeve 70 and can be abutted on the second transmission part 51.
