Technical Field

[0001] The present application relates to the field of terminal device hardware, and in particular, to a switch assembly, a key module, a combination key and an electronic device. Background Art

[0002] Thinness and lightness is a development trend of portable electronic devices, such as mobile phones, foldable screen devices and tablet computers. The thickness and weight of electronic devices are important factors affecting user experience.

[0003] The switch assembly arranged on the frame of the electronic device largely limits the thickness of the electronic device. How to improve the structure of the switch assembly without reducing the functional reliability of the switch assembly to reduce the limitation of the switch assembly on further thinning of the electronic device is an issue worth considering. Summary of the invention

[0004] The present application provides a switch assembly, wherein both contacts of a terminal pair of the switch assembly can be accommodated in a container of the switch assembly and used to connect the switch assembly to an external circuit. When the external circuit is connected to the switch assembly, it is not necessary to stack the contacts on the back of the switch assembly, and the external circuit can be more reliably electrically connected to the switch assembly. No glue filling space needs to be reserved in the width direction of the switch assembly, which is generally beneficial to reducing the space occupied by the switch assembly in the thickness direction of the electronic device when the switch assembly is used.

[0005] In the first aspect, a switch assembly is provided, comprising: a housing member, a spring sheet, a push rod, a protective film, a first terminal and a second terminal, wherein the housing member accommodates the spring sheet, the push rod, the first terminal and the second terminal; the first terminal and the second terminal are spaced apart, the first terminal comprises a first abutting portion and a first contact, the second terminal comprises a second abutting portion and a second contact, the first contact and the second contact are used for electrically connecting the switch assembly with an external circuit; the spring sheet and the first abutting portion are spaced apart, and the spring sheet contacts the second abutting portion; the push rod is located on a side of the spring sheet away from the first abutting portion; the protective film is located on a side of the push rod away from the spring sheet; wherein the first contact and the second contact are adjacently arranged, the first contact and the second contact are located outside the range of the projection of the protective film on the first plane, the first contact and the second contact are located on the same side of the protective film, and the first plane is the plane where the housing member is located.

[0006] In some scenarios, the first terminal may also be referred to as a first connection terminal, the second terminal may also be referred to as a second connection terminal, and the first terminal and the second terminal may form a terminal pair. The first terminal and the second terminal being spaced apart may also be understood as the two terminals not contacting each other.

[0007] In a possible implementation, both the first terminal and the second terminal may be conductive metal sheets. The abutting portion and the contact point of the terminal should be understood as conductive sheets, conductive plates or conductive blocks with a certain contact area.

[0008] It should be understood that the spring piece is made of a conductive material, and in some scenarios, the spring piece may be a conductive metal sheet.

[0009] In the technical solution, the contacts of the first terminal and the second terminal are located in the same area of ​​the container. When the external circuit board is connected to the switch assembly through the contacts of the terminals, the external circuit board does not need to be arranged on the back of the switch assembly, and the space occupied by the switch assembly in the thickness direction is reduced in actual use. In addition, since the external circuit board does not need to be arranged on the back of the switch assembly, there is no need to set a filling medium on the back of the switch assembly, and there is no need to reserve space for the filling medium. The space occupied by the switch assembly in the width direction (i.e., the thickness direction of the electronic device) is reduced, which is conducive to further thinning of the electronic device.

[0010] In a possible implementation, the plane where the first contact point is located is coplanar with the plane where the first abutting portion is located, and the plane where the second contact point is located is coplanar with the plane where the second abutting portion is located.

[0011] The plane where the contact point is located is coplanar with the plane where the abutment portion is located, which should be understood as coplanar, approximately coplanar, or substantially coplanar within the allowable range of measurement error.

[0012] In a possible implementation, the accommodation member is formed by injection molding according to the shape of the terminal, that is, the shape and size of the accommodation member are determined according to the shape and size of the terminal.

[0013] In another possible implementation, the shape and size of the terminal are determined after the shape and size of the accommodating space such as the inner groove of the accommodating member are determined.

[0014] Since the contact and the abutment surface of the terminal are basically coplanar, this further ensures that the external circuit connected to the contact does not need to be arranged below the terminal (i.e., below the switch assembly). In actual use, the space occupied by the switch assembly in the thickness direction is reduced, and the space occupied by the switch assembly in the width direction (i.e., the thickness direction of the electronic device) is reduced.

[0015] In combination with the first aspect, in certain implementations of the first aspect, the first terminal further includes a first connecting section, the first abutting portion and the first contact are connected through the first connecting section, the first connecting section includes a first transition portion, and a plane where the first transition portion is located is inclined with the first plane.

[0016] In a possible implementation manner, there may be multiple first transition portions.

[0017] It should be understood that in a possible implementation, the first connecting section may not include the first transition portion that is arranged obliquely, or in other words, the plane where the first terminal is located is parallel to the first plane.

[0018] The inclined transition part is provided on the first terminal, which is conducive to fully utilizing the space in the thickness direction of the container and improving the space utilization rate in the container. In addition, the inclined transition part is also conducive to achieving the firmness of the first terminal in the container.

[0019] In combination with the first aspect, in certain implementations of the first aspect, the second terminal further includes a second connecting section, the second abutting portion and the second contact are connected through the second connecting section, the second connecting section includes a fourth transition portion, and a plane where the fourth transition portion is located is inclined with the first plane.

[0020] In a possible implementation manner, there may be multiple second transition parts.

[0021] It should be understood that in a possible implementation, the first connecting section may not include the second transition portion that is arranged obliquely, or in other words, the plane where the second terminal is located is parallel to the first plane.

[0022] The inclined transition part is provided on the second terminal, which is conducive to fully utilizing the space in the thickness direction of the container and improving the space utilization rate in the container. In addition, the inclined transition part is also conducive to achieving the firmness of the second terminal in the container.

[0023] In combination with the first aspect, in certain implementations of the first aspect, the first abutting portion includes a first abutting surface, the second abutting portion includes a second abutting surface, and the distance from the first reference point on the spring sheet to the first abutting surface is greater than the distance from the first reference point to the second abutting surface.

[0024] It should be understood that the first reference point is any reference point on the spring piece.

[0025] In some scenarios, the above technical solution can also be understood as the first abutting surface being located on a side of the second abutting surface close to the back surface of the receiving component.

[0026] Properly increasing the distance between the first abutting surface and the spring piece is beneficial to increasing the deformation travel space of the spring piece during the force deformation process, which is beneficial to increasing the intensity of the feedback of the switch assembly to the user's pressing operation during use, thereby improving the user's experience.

[0027] In combination with the first aspect, in some implementations of the first aspect, an embedding portion is provided at one end of the first abutting portion away from the first contact point, and the embedding portion is embedded in the accommodating member.

[0028] The first abutting portion is partially embedded in the accommodating member, and the first terminal can be more firmly fixed in the accommodating member, which is beneficial to improving the reliability of the function of the switch assembly.

[0029] In combination with the first aspect, in some implementations of the first aspect, the second abutting portion is partially embedded in the receiving member.

[0030] The second abutting portion is partially embedded in the receiving body, and the second terminal can be more firmly fixed in the receiving body, which is beneficial to improving the reliability of the switch assembly function.

[0031] In combination with the first aspect, in certain implementations of the first aspect, the accommodating member includes a first accommodating body and a second accommodating body, the first accommodating body accommodating a first abutting portion, a second abutting portion, a spring sheet and a push rod, and the second accommodating body accommodating a first contact and a second contact.

[0032] In a possible implementation, the first containing body is a trough body.

[0033] In a possible implementation, the second containing body may be in the shape of a groove, a boss, or a plane.

[0034] Providing a housing body in the housing for accommodating other components of the switch assembly is conducive to improving the space utilization rate inside the housing and reducing the overall volume of the switch assembly. In addition, accommodating the contact and the abutment of the terminal pair in two different housing bodies is conducive to reducing the interference of the contact with the abutment when connecting with the external circuit board, and reducing the adverse effects of moisture in the environment on the abutment of the terminal pair.

[0035] In combination with the first aspect, in certain implementations of the first aspect, a first sub-container and a second sub-container are disposed at the bottom of the first container, the second sub-container is disposed around the first sub-container, the first sub-container accommodates a first abutting portion, and the second sub-container accommodates a second abutting portion; a third sub-container and a fourth sub-container are disposed at the bottom of the second container, the third sub-container accommodates a first contact, and the fourth sub-container accommodates a second contact.

[0036] In a possible implementation, the first sub-container may be in the shape of a groove, a boss, or a plane.

[0037] In a possible implementation, the second sub-container can be any one of a groove, a boss or a plane. Exemplarily, the second sub-container is an arc groove or a U-shaped groove.

[0038] Further providing a first sub-container and a second sub-container for accommodating the abutment portion at the bottom of the first containment body can help to further improve the utilization rate of the internal space of the containment member. When the spring pieces and the push rods are stacked in the first containment body, it can help to reduce the distance between the topmost component and the bottom of the first containment body after multiple components are stacked, which can help to reduce the thickness of the containment member to a certain extent.

[0039] Further opening a third sub-container and a fourth sub-container for accommodating the contacts of the terminals at the bottom of the second container body can help to further improve the utilization rate of the internal space of the container. When a part of the external circuit board is accommodated in the second container body, the distance between the upper surface of the external circuit board and the back surface of the container is shorter, which is helpful to reduce the thickness of the switch assembly to a certain extent.

[0040] In combination with the first aspect, in certain implementations of the first aspect, a first channel is opened at the bottom of the container, the first channel connects the first sub-container and the third sub-container, the first terminal also includes a first connecting section, the first connecting section connects the first abutting portion and the first contact, and the first connecting section is accommodated in the first channel.

[0041] A connecting section for accommodating the abutting portion connecting the first terminal and the contact is opened at the bottom of the container, which further improves the utilization efficiency of the internal space of the container. The connecting section does not need to occupy additional space in the width direction of the container, which is also helpful to reduce the width of the switch assembly to a certain extent.

[0042] In combination with the first aspect, in certain implementations of the first aspect, a second channel is opened at the bottom of the container, the second channel connects the second sub-container and the fourth sub-container, the second terminal also includes a second connecting section, the second connecting section connects the second abutting portion and the second contact, and the second connecting section is accommodated in the second channel.

[0043] A connecting section for accommodating the abutting portion and the contact connecting the second terminal is opened at the bottom of the container, which further improves the utilization efficiency of the internal space of the container. The connecting section does not need to occupy additional space in the width direction of the container, which is also helpful to reduce the width of the switch assembly to a certain extent.

[0044] In a possible implementation, the second accommodating body is a groove body, a first notch is formed on one side of the accommodating member, and the first notch is communicated with the second accommodating body.

[0045] In a possible implementation manner, the first notch is formed on another side wall of the container opposite to the second channel, or in other words, the first notch avoids the second channel.

[0046] A notch is provided on the side wall of the container, and the external circuit board can be directly inserted into the second container through the notch to connect with the contact point of the terminal. The direction in which the first notch is connected to the container can be perpendicular to the plane where the side wall of the container is located, thereby reducing the difficulty of inserting the external circuit board into the notch, simplifying the complexity of assembling the switch assembly, and to a certain extent also reducing the complexity of opening the notch in the container.

[0047] In combination with the first aspect, in certain implementations of the first aspect, the first channel includes a first bending portion, an extension direction of the first bending portion is inclined to the first plane, and the first connecting section includes a first transition portion, and the first transition portion is in contact with an inner wall of the first bending portion.

[0048] In a possible implementation, there are two first bends, one of which is disposed close to the first sub-container, and the other is disposed close to the third sub-container, and the extension directions of the two first bends are inclined to the bottom surface of the first sub-container. In a possible implementation, the first connecting section further includes a third transition portion, and the third transition portion is in contact with the inner wall of the other first bend.

[0049] A bending portion is provided in the first channel, and the transition portion of the first terminal is fitted with the bending portion of the channel, so that the bending portion can play a limiting role to a certain extent, so that the first terminal fits better in the receiving body, mixing is less likely to occur, and the function of the switch assembly is more reliable.

[0050] In combination with the first aspect, in certain implementations of the first aspect, the second channel includes a second bending portion, an extension direction of the second bending portion is inclined to the first plane, and the second connecting section includes a fourth transition portion, and the fourth transition portion is in contact with an inner wall of the second bending portion.

[0051] In a possible implementation, there are two second bends, one of which is disposed close to the second sub-container, and the other is disposed close to the fourth sub-container, and the extension directions of the two second bends are inclined to the bottom surface of the second sub-container. In a possible implementation, the second connecting section further includes a sixth transition portion, and the sixth transition portion is in contact with the inner wall of another second bend portion.

[0052] A bending portion is provided in the second channel, and the transition portion of the second terminal is fitted with the bending portion of the channel, so that the bending portion can play a limiting role to a certain extent, so that the second terminal fits better in the receiving body, mixing is less likely to occur, and the function of the switch assembly is more reliable.

[0053] In combination with the first aspect, in certain implementations of the first aspect, the first container body and the second container body are both trough bodies, the first container body and the second container body are spaced apart from each other, and the top surface of the trough wall of the first container body is located on the side of the top surface of the trough wall of the second container body away from the back side of the container.

[0054] In some scenarios, the bottom surface of the first container and the bottom surface of the second container are in the same plane. The above technical solution can also be understood as that the height of the groove wall of the first container is greater than the height of the groove wall of the second container, or in other words, the depth of the first container is greater than the depth of the second container.

[0055] Since the second container needs to accommodate the external circuit board, the height of the side wall of the first container that accommodates components such as springs and push rods is set higher than the side wall of the second container. The contact connection process between the external circuit board and the terminal is not likely to have an adverse effect on the components in the first container (dust, water vapor and other adverse factors that may affect the normal operation of the switch assembly may be introduced during the connection process of the external circuit board).

[0056] In a possible implementation, the distance from the third sub-containing body to the side wall of the containing member is equal to the distance from the fourth sub-containing body to the same side wall.

[0057] In some scenarios, the above technical solution can also be understood as: the arrangement direction of the third sub-container and the fourth container is parallel to the plane where the side wall of the containment component is located.

[0058] The distances from the two contacts of the terminal pair to the side wall of the container are the same, which can to a certain extent reduce the length of the external circuit board that needs to be accommodated in the second container, which is beneficial to reducing the width of the second container, reducing the width of the switch assembly, and achieving further thinning of the electronic device.

[0059] In combination with the first aspect, in certain implementations of the first aspect, the first sub-container and the second sub-container are both trough bodies, the first sub-container and the second sub-container are separated by a first sub-container wall, and a first arc-shaped boss is provided on the top of the first sub-container wall.

[0060] In a possible implementation manner, the top surface of the first boss and the top surface of the second abutting portion are in the same plane.

[0061] The first boss is similar to a partition structure arranged between the first abutting portion and the second abutting portion. The spring sheet in contact with the second abutting portion is blocked by the first boss and is not easy to contact with the first abutting portion. Therefore, the arrangement of the first boss is conducive to improving the stability of the structure and performance of the switch assembly provided in the present application.

[0062] In combination with the first aspect, in certain implementations of the first aspect, the first containing body is a trough body, and the protective film cover is disposed on the top surface of the side wall of the first containing body.

[0063] The provision of the protective film can prevent factors such as dust and water vapor outside the switch assembly from affecting the normal operation of the components in the first container, which is beneficial to improving the reliability of the switch assembly function.

[0064] In combination with the first aspect, in certain implementations of the first aspect, the switch assembly further includes a first connecting plate and a second connecting plate, the first connecting plate and the second connecting plate are located on the same surface of the accommodating member, the first connecting plate is covered on the second accommodating body, the second connecting plate is located at one end of the accommodating member away from the second accommodating body, and a side of the first connecting plate away from the accommodating member and a side of the second connecting plate away from the accommodating member are in the same plane.

[0065] In a possible implementation, the first connecting sheet and the second connecting sheet are coated with adhesive material so that they can be used for fixed connection with other components during the installation process of the switch assembly.

[0066] The first connecting piece and the second connecting piece have one side away from the receiving member and are coplanar, that is, they can form a plane, which is beneficial for the mutual fit between the bracket arranged outside the switch assembly and the switch assembly, and is beneficial for improving the ease of combination and installation of the switch assembly with other components.

[0067] In combination with the first aspect, in certain implementations of the first aspect, both ends of the container further include an outwardly convex and / or inwardly concave fixing structure.

[0068] Fixed structures are arranged at both ends of the receiving member, which can be used for the subsequent positioning and connection of the switch assembly with structures such as a bracket.

[0070] In a possible implementation, the support plate may be made of a metal material or an inorganic non-metal material, such as a steel plate or a glass fiber reinforced plate.

[0071] The support plate plays the role of reinforcing the receiving member to a certain extent, which is beneficial to reducing the probability of deformation and damage of the switch assembly when subjected to external force, and improving the durability of the switch assembly.

[0075] The setting of the bracket can protect the switch assembly to a certain extent, and the adapter plate can realize the interconnection between the key module and the external circuit.

[0125] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0126] Before introducing the embodiments of the present application, some professional terms that may be used in the following content are first explained.

[0127] The patch connection process is a technology for mounting electronic components on printed circuit boards. It is mainly divided into two types: horizontal patch connectors and vertical patch connectors. Horizontal patch connectors are surface mounted components without pins or short leads. They need to print solder paste on the circuit board first, then mount the components on the solder paste through a patch machine, and finally melt the solder paste through a reflow oven to firmly bond the components to the circuit board. Vertical patch connectors are direct-insert packaged components. They need to punch holes in the circuit board first, then insert the pins of the components into the holes, and finally solder the pins to the circuit board through wave soldering or manual soldering.

[0128] Underfill glue is an organic adhesive used to reinforce the solder joints of electronic components on circuit boards, such as epoxy resin.

[0129] Flexible printed circuit (FPC), also known as flexible circuit board, is a printed circuit board that is characterized by light weight, thin thickness, softness and flexibility. It is mainly used in products such as mobile phones, laptops and LCD screens.

[0130] Metal dome, also known as metal shrapnel, is mainly used in products such as membrane switches, micro switches and printed circuit boards. It has the characteristics of smooth contact, strong conductivity and stable rebound.

[0131] Terminals, also known as wiring terminals, are connectors used to achieve electrical connections. In some examples, the terminals can be metal sheets encapsulated in insulating plastic.

[0132] Figure 1 Shown is an electronic device 10 provided in an embodiment of the present application, which may include a first display screen 11, a middle frame 12, a back panel (or a cover panel, not shown in the figure), a "volume +" button 21, a "volume -" button 22, a power button 23, etc.

[0133] The middle frame 12 can be used to fix the first display screen 11 and the back panel. The middle frame 12, the first display screen 11 and the back panel can form a closed accommodation space, which can be used to accommodate other electronic components of the electronic device 10, such as: batteries, motherboards, camera modules, etc.

[0134] The middle frame 12 may be provided with a plurality of openings, which may be provided on one frame, two frames arranged opposite to each other, or two frames arranged adjacent to each other of the middle frame 12. The plurality of openings may correspond to the aforementioned "volume +" button 21, "volume -" button 22, and power button 23.

[0135] The components for realizing the functions of the "volume +" button 21, the "volume -" button 22 and the power button 23 can be accommodated in the aforementioned accommodation space, and these components can be arranged near the aforementioned buttons. In other words, the components for realizing the functions of the aforementioned multiple buttons are arranged between the first display screen 11 and the back plate of the electronic device 10.

[0136] In some examples, the electronic device 10 may be a folding screen device, and the electronic device 10 may include an inner screen and an outer screen. For example, the first display screen 11 is the outer screen of the electronic device 10, and the inner screen of the electronic device 10 may be arranged opposite to the first display screen 11, that is, located near the back panel of the electronic device 10. In this case, the components for realizing the functions of the aforementioned multiple buttons may be regarded as being arranged between the inner screen and the outer screen of the electronic device 10.

[0137] The distance between the first display screen 11 and the back panel or the distance between the inner screen and the outer screen of the electronic device can be regarded as the thickness of the electronic device 10 (i.e. Figure 1 As mentioned above, factors such as the structure, size, and arrangement of the buttons of the electronic device 10 determine the thickness of the electronic device 10 to a certain extent.

[0138] Figure 2 A schematic diagram of the structure and installation position of a first button module of an electronic device 10 is provided as an example. The first button module may be any one of the related components of the "volume +" button 21, the related components of the "volume -" button 22, and the related components of the power button 23 of the aforementioned electronic device 10. The first button module may include a first keycap 301, a first switch assembly 302, a filling medium 303, and a first circuit board assembly 304.

[0139] The first switch component 302 and the first circuit board component 304 can be connected by a patch process. In the case of connection by the patch process, there will be a certain gap between the first switch component 302 and the first circuit board component 304. In order to improve the reliability of the first key module and extend the service life of the first key module, bottom filling glue can be applied between the first switch component 302 and the first circuit board component 304 and on the periphery of the first switch component 302 to form a filling medium 303.

[0140] like Figure 2 As shown, the size of the first circuit board assembly 304 in the Z-axis direction should be larger than the size of the first switch assembly 302 in the Z-axis direction, so that when filling the bottom filling glue, the glue will not overflow to the side of the first circuit board assembly 304 away from the first switch assembly 302, and the filling medium 303 formed by the glue can be wrapped around the periphery of the first switch assembly 302.

[0141] The filling medium 303 provided to enhance the reliability of the first button module will occupy a certain space in the Z-axis direction. For example, the two parts of the filling medium 303 in the Z-axis direction of the first switch assembly 302 have a size of about 0.5 mm in the Z-axis direction. In order to reduce the adverse effect of the filling medium 303 on the first circuit board assembly 304, the size of the first circuit board assembly 304 in the Z-axis direction also needs to be increased. These two factors limit the further thinning of the thickness of the electronic device to a certain extent.

[0142] In addition, due to the limitations of the processing technology, it is difficult for the filling medium 303 to completely fill the gap between the first switch component 302 and the first circuit board component 304. In other words, even if the filling medium 303 is set, the solder pins or solder of the first switch component 302 located in the gap will still be at risk of being exposed, which also reduces the reliability of the first button module.

[0143] In order to reduce the volume of the key module as much as possible without compromising the reliability of the key module and reduce the space occupied by the key module in the thickness direction of the electronic device, the present application provides a second switch assembly 500 and a second key module 40, which are now introduced as follows.

The adapter plate 700 can be electrically connected to the second switch component 500 to realize the exchange of control signals, data signals, etc. between the second switch component 500 and the external circuit.

[0146] The following first introduces the structure of the second switch assembly 500 , and then explains the connection between the second switch assembly 500 and the bracket 600 , and the connection between the second switch assembly 500 and the adapter plate 700 .

Exemplarily, four abutting blocks 5431 are provided on the first abutting portion 5430, and the four abutting blocks 5431 are all in the shape of a column with a radial cross section of a quarter circle, and the four abutting blocks are spaced apart from each other.

[0179] In some examples, the first abutting portion 5430 may also be provided with an embedding portion 5432, and the embedding portion 5432 may be provided at one end of the first abutting portion 5430 away from the first extension portion 5440. The embedding portion 5432 may be inserted into the gap between the first sub-groove 5511 and the first extension portion 5532 of the aforementioned receiving member 550, thereby limiting the position of the first terminal 5410 in the receiving member 550.

[0180] The first extension portion 5440 can be regarded as a portion formed by the first abutting portion 5430 extending along the aforementioned first channel 5540 to the third sub-groove 5521. The first extension portion 5440 may include a first transition portion 5441, a second transition portion 5442, a third transition portion 5443 and a first contact 5444, wherein one end of the first transition portion 5441 is connected to the aforementioned first abutting portion 5430, and the other end is connected to the second transition portion 5442. The second transition portion 5442, the third transition portion 5443 and the first contact 5444 are connected in sequence, and the first contact 5444 is accommodated in the third sub-groove 5521.

[0181] The plane where the second transition portion 5442 is located, the plane where the first abutting portion 5430 is located, and the plane where the first contact 5444 is located are substantially parallel, and the plane where the first abutting portion 5430 is located is substantially coplanar with the plane where the first contact 5444 is located, or in other words, the first abutting portion 5430 and the first contact 5444 are substantially at the same height, or in other words, when the first terminal 5410 is installed in the accommodating member 550, the distances from the plane where the first abutting portion 5430 is located and the plane where the first contact 5444 is located to the back of the accommodating member 550 are substantially equal. The distance from the plane where the second transition portion 5442 is located to the back of the accommodating member 550 is smaller than the distance from the plane where the first abutting portion 5430 is located or the plane where the first contact 5444 is located to the back of the accommodating member 550.

[0182] The first transition portion 5441 is arranged obliquely with the first abutting portion 5430, and the third transition portion 5443 is arranged obliquely with the second transition portion 5442. When the first terminal 5410 is installed in the accommodating member 550, the first transition portion 5441 and the third transition portion 5443 are both located at the first bending portion 5541 of the first channel 5540, and the second transition portion 5442 is located between the two first bending portions 5541. The inclination angle of the first transition portion 5441 and the inclination angle of the third transition portion 5443 correspond to the inclination angle of the first bending portion 5541 where the first and third transition portions 5443 are located, respectively, so that the portion of the first terminal 5410 in the first channel 5540 (i.e., the first transition portion 5441, the second transition portion 5442 and the third transition portion 5443) can fit the first channel 5540 as closely as possible.

[0183] It should be understood that the inner diameter of the first channel 5540 should be slightly larger than the width or thickness of the portion of the first terminal 5410 within the first channel 5540. For example, the spacing between the upper surface and the lower surface of the first channel 5540 should be slightly larger than the thickness of the portion of the first terminal 5410 within the first channel 5540, and the spacing between the left and right sides of the first channel 5540 should be slightly larger than the width of the portion of the first terminal 5410 within the first channel 5540.

[0184] In some examples, the first terminal 5410 may not be provided with the aforementioned inclined first transition portion 5441 and third transition portion 5443. In other words, the first terminal 5410 may be plate-like, and the first abutment portion 5430 and the first contact 5444 of the first terminal 5410 may all be in the same plane.

[0185] Fig.14 The second terminal 5420 is shown, and the second terminal 5420 may include a second abutting portion 5450 and a second extending portion 5460, wherein the second abutting portion 5450 is generally U-shaped, and the second extending portion 5460 may be considered to be formed by one end of the second abutting portion 5450 extending from the second sub-groove 5512 along the second channel 5550 to the fourth sub-groove 5522. When the second terminal 5420 and the spring sheet 530 are installed in the receiving member 550, the spring sheet 530 may abut against the second abutting portion 5450 of the second terminal 5420.

[0186] In some examples, the second abutting portion 5450 may include a first limiting portion 5451 and a second limiting portion 5452, the first limiting portion 5451 and the second limiting portion 5452 may be disposed at both ends of the second abutting portion 5450 (i.e., the position of the U-shaped opening), the first limiting portion 5451 and the second limiting portion 5452 may be close to each other, and the distance between the first limiting portion 5451 and the second limiting portion 5452 may be smaller than the distance between the U-shaped openings. In other words, the first limiting portion 5451 and the second limiting portion 5452 may be considered to be obtained by extending from both ends of the second abutting portion 5450 to the inner side of the opening position.

[0187] The U-shaped second abutment portion 5450 can be accommodated in the annular second sub-groove 5512 of the accommodating member 550, and the first limiting portion 5451 and the second limiting portion 5452 can clamp the second terminal 5420 in the second sub-groove 5512, so that the second terminal 5420 is installed more firmly and the reliability of the second switch assembly 500 is higher.

[0188] In some examples, the second extension portion 5460 may include a fourth transition portion 5461, a fifth transition portion 5462, a sixth transition portion 5463, and a second contact 5464. One end of the fourth transition portion 5461 is connected to one end of the second abutting portion 5450, and the other end is connected to the fifth transition portion 5462. The fifth transition portion 5462, the sixth transition portion 5463, and the second contact 5464 are connected in sequence, and the second contact 5464 is accommodated in the fourth sub-groove 5522.

[0189] The plane where the fifth transition portion 5462 is located, the plane where the second abutting portion 5450 is located, and the plane where the second contact 5464 is located are substantially parallel, and the plane where the second abutting portion 5450 is located is substantially coplanar with the plane where the second contact 5464 is located, or in other words, the second abutting portion 5450 and the second contact 5464 are substantially at the same height, or in other words, when the second terminal 5420 is installed in the accommodating member 550, the distances from the plane where the second abutting portion 5450 is located and the plane where the second contact 5464 is located to the back of the accommodating member 550 are substantially equal. The distance from the plane where the fifth transition portion 5462 is located to the back of the accommodating member 550 is smaller than the distance from the plane where the second abutting portion 5450 or the plane where the second contact 5464 is located to the back of the accommodating member 550.

[0190] The fourth transition portion 5461 is arranged obliquely with the second abutting portion 5450, and the sixth transition portion 5463 is arranged obliquely with the fifth transition portion 5462. When the second terminal 5420 is installed in the accommodating member 550, the fourth transition portion 5461 and the sixth transition portion 5463 are both located at the second bending portion 5551 of the second channel 5420, and the fifth transition portion 5462 is located between the two second bending portions 5551. The inclination angle of the fourth transition portion 5461 and the inclination angle of the sixth transition portion 5463 correspond to the inclination angle of the second bending portion 5551 where the fourth transition portion 5461 and the sixth transition portion 5463 are located, respectively, so that the portion of the second terminal 5420 in the second channel 5550 (and the fourth transition portion 5461, the fifth transition portion 5462 and the sixth transition portion 5463) can fit the second channel 5550 as closely as possible.

[0191] It should be understood that the inner diameter of the second channel 5550 should be slightly larger than the width or thickness of the portion of the second terminal 5420 within the second channel 5550. For example, the spacing between the upper surface and the lower surface of the second channel 5550 should be slightly larger than the thickness of the portion of the second terminal 5420 within the second channel 5550, and the spacing between the left and right sides of the second channel 5550 should be slightly larger than the width of the portion of the second terminal 5420 within the second channel 5550.

[0192] In some examples, the second contact 5464 is connected to the sixth transfer portion 5463 via the first connecting arm 5465 , and the connection direction between the first connecting arm 5465 and the second contact 5464 may be perpendicular to the direction of interconnection among the fourth transfer portion 5461 , the fifth transfer portion 5462 , and the sixth transfer portion 5463 .

[0193] In some scenarios, the connection relationship between the aforementioned second contact 5464 and the sixth adapter portion 5463 can also be understood as: the second contact 5464 includes a right-angle connecting arm 5465, one end of the right-angle connecting arm 5465 is connected to the sixth adapter portion 5463, and the other end of the right-angle connecting arm 5465 is connected to the second contact 5464.

[0194] In some examples, the second terminal 5420 may not be provided with the aforementioned inclined fourth transition portion 5461 and sixth transition portion 5463. In other words, the second terminal 5420 may be plate-like, and the second abutting portion 5450 and the second contact 5464 of the second terminal 5420 may all be in the same plane.

[0195] Fig.15 and Fig.16The structure diagram of the spring piece 530 is shown. The spring piece 530 may include one or more sub-spring pieces. In the case where the spring piece 530 includes a plurality of sub-spring pieces, the plurality of sub-spring pieces may be stacked on each other along the thickness direction to form the spring piece 530. Each sub-spring piece may include a pressing portion 5310, a first supporting portion 5320 and a second supporting portion 5330. The first supporting portion 5320 and the second supporting portion 5330 may be arranged at the periphery of the pressing portion 5310.

[0196] The pressing portion 5310, the first supporting portion 5320 and the second supporting portion 5330 may all be in the shape of a thin plate or a thin sheet. The first supporting portion 5320 and the second supporting portion 5330 are both fixedly connected to the pressing portion 5310. In some examples, the pressing portion 5310 may be approximately circular, the first supporting portion 5320 and the second supporting portion 5330 may both be in the shape of an arc, and the first supporting portion 5320 and the second supporting portion 5330 may be symmetrically arranged on both sides of the pressing portion 5310. The first supporting portion 5320 may be arranged obliquely with the pressing portion 5310, and the second supporting portion 5330 may also be arranged obliquely with the pressing portion 5310. Exemplarily, the angle between the plane where the first supporting portion 5320 is located and the plane where the pressing portion 5310 is located is α, and the angle between the plane where the second supporting portion 5330 is located and the plane where the pressing portion 5310 is located is β, α=β.

[0197] The pressing portion 5310, the first supporting portion 5320 and the second supporting portion 5330 included in the split spring piece can all be made of conductive materials. When the spring piece 530 is installed in the container 550, the first supporting portion 5320 and the second supporting portion 5330 of the spring piece 530 can be supported on the plane formed by the first boss 5533 and the third extension portion 5534 of the container 550, and can contact the portion of the second terminal 5420 located in the second sub-groove 5512. The pressing portion 5310 can be located above the first abutting portion 5430 of the first terminal 5410, or in other words, the pressing portion 5310 can be spaced apart from the first abutting portion 5430.

[0198] The material constituting the spring piece 530 should have an elastic modulus less than or equal to a preset threshold value, or in other words, when pressure is applied to the pressing portion 5310, the spring piece 530 can be deformed, the angle between the plane where the first support portion 5320 is located and the plane where the pressing portion 5310 is located and / or the angle between the plane where the second support portion 5330 is located and the plane where the pressing portion 5310 is located can be reduced, and the pressing portion 5310 of the spring piece 530 can approach and contact the first abutting portion 5430.

[0199] Fig.17 and Fig.18FIG. 5 is a schematic diagram of the structure of the protective film 510. The protective film 510 is similar to a hat. When it is placed on the top of the first tank body 5510, the protective film 510 can prevent moisture, dust, etc. outside the device from entering the tank body and affecting the normal operation of the devices and components in the first tank body 5510. The protective film 510 may include a top 5110, an eaves 5120, and a connecting piece 5130 for connecting the top 5110 and the eaves 5120.

[0200] The eaves 5120 can overlap the top surface of the side wall of the first trough body 5510 of the accommodating member 550, and the shape of the eaves 5120 can match the shape of the first trough body 5510. The eaves 5120 has a certain width so that the eaves 5120 can have a sufficiently large contact area when overlapping the top surface of the side wall of the first trough body 5510.

[0201] The top portion 5110 may be used to accommodate part or all of the push rod 520, and the shape of the top portion 5110 may match the shape of the push rod 520. For example, Fig.14 As shown, the push rod 520 can be cylindrical, and the top surface 5111 of the top 5110 can be circular, and the radius of the top surface 5111 can be slightly larger than the cross-sectional radius of the cylindrical push rod 520. The top 5110 can include a side wall 5112 connected to the top surface 5111, and the side wall 5112 is arranged around the outer periphery of the top surface 5111 and connected to the outer periphery of the top surface 5111. One end of the side wall 5112 away from the top surface 5111 can be connected to the connecting piece 5130. The top 5110 provided with the top surface 5111 and the side wall 5112 is similar to an inverted cylinder, and the cylindrical push rod 520 can be partially or completely accommodated in the cylinder. The radius of the arc formed by one end of the side wall 5112 connected to the connecting piece 5130 can be larger than the radius of the arc formed by one end of the side wall 5112 connected to the top surface 5111, so as to facilitate the inclined setting of the connecting piece 5130 and control the size and shape of the eaves 5120. The connecting piece 5130 may be formed by combining a plurality of sheet-shaped sub-connecting pieces, thereby helping to reduce the difficulty of processing the protective film 510 .

[0202] The surface where the push rod 520 contacts the protective film 510 can be referred to as the first contact surface, and the surface where the push rod 520 contacts the spring 530 can be referred to as the second contact surface. The first contact surface and the second contact surface are arranged opposite to each other. In some examples, in order to improve the fit between the push rod 520 and the protective film 510, a transition zone can be provided at the connection position between the first contact surface and the side wall of the push rod, and the transition zone can be an arc-shaped chamfer formed by physical grinding or chemical treatment of the outer periphery of the first contact surface. In some examples, in order to improve the fit between the push rod 520 and the spring, the shape of the second contact surface can be determined according to the shape of the spring 530 and the side facing the push rod 520. For example, if the side of the spring 530 facing the push rod 520 is an arc surface, the second contact surface of the push rod 520 can also be a contact surface with a certain curvature and a depression.

[0203] In some examples, the switch assembly 500 may further include a support plate 560, such as Fig.19 As shown, the support plate 560 may include a second notch 562 corresponding to the first notch 5523 on the container 550, a third fixing portion 561A corresponding to the first fixing portion 559A on the container 550, and a fourth fixing portion 561B corresponding to the second fixing portion 559B on the container 550.

[0204] The second notch 562 can cooperate with the first notch 5523 to accommodate a portion of the adapter plate 700, and the shape and size of the second notch 562 can be substantially consistent with the first notch 5523. The third fixing portion 561A can cooperate with the first fixing portion 559A, and the fourth fixing portion 561B can cooperate with the second fixing portion 559B. These two sets of fixing portions can jointly realize the fixed connection between the bracket 600 and the switch assembly 500.

[0205] In some examples, the first fixing portion 559A, the second fixing portion 559B, the third fixing portion 561A, and the fourth fixing portion 561B may all be convex structures having the same shape and size.

[0206] In some examples, the first fixing portion 559A, the second fixing portion 559B, the third fixing portion 561A, and the fourth fixing portion 561B may all be concave structures having the same shape and size.

[0207] In some examples, one of the two groups of fixing structures, the first fixing portion 559A and the third fixing portion 561A, and the second fixing portion 559B and the fourth fixing portion 561B, may be a concave structure, and the other group may be a convex structure.

[0208] The support plate 560 may be disposed on the back of the container 550 and may be fixedly connected to the back of the container 550. In some examples, the support plate 560 may be made of a material with good mechanical properties. For example, a metal material or an inorganic non-metallic material with high rigidity and hardness. Exemplarily, the support plate 560 may be a steel plate or a glass fiber reinforced plate. When the support plate 560 is disposed on the back of the container 550, the support plate 560 may play a role in reinforcing the container 550, thereby reducing the probability of the switch assembly 500 being damaged when subjected to external forces.

[0209] In some examples, the support plate 560 is provided with one or more first through holes in the thickness direction, and the one or more first through holes can cooperate with one or more protrusions provided on the side (i.e., the back side) of the container 550 facing the support plate 560, so as to enhance the firmness of the connection between the support plate 560 and the container 550. Specifically, the protrusion on the back side of the container 550 can extend into the first through hole on the support plate 560, and the side wall of the protrusion can abut against the inner wall of the first through hole.

[0210] In some examples, the switch assembly 500 may also be provided with a connecting piece group 570, combined with Figure 4 and Fig. 20 , the connecting piece group 570 may include a first connecting piece 571 and a second connecting piece 572, and the first connecting piece 571 and the second connecting piece 572 are separately arranged. The first connecting piece 571 may be arranged close to the second slot body 5520, and the second connecting piece 572 may be arranged close to the first slot body 5510. In some examples, the first connecting piece 571 may be covered on the top of the second slot body 5520, and when a part of the adapter plate 700 is accommodated in the second slot body 5520, the first connecting piece 571 may be pressed on the part of the adapter plate 700 accommodated in the second slot body 5520, so that the contact between the adapter plate 700 and the terminal pair 540 is more firm and stable.

[0211] The second connecting piece 572 can be disposed on an end of the receiving member 550 away from the first connecting piece 571, and the second connecting piece 572 can avoid the second slot body wall 5560 of the first slot body 5510. In some examples, the thickness of the first connecting piece 571 is equal to the thickness of the second connecting piece 572, and the first connecting piece 571 and the second connecting piece 572 can be substantially in the same plane away from the receiving member 550. When the bracket 600 is connected to the switch assembly 500, the connection surfaces of the two can be more closely fitted, which is conducive to improving the reliability of the connection between the bracket 600 and the switch assembly 500.

[0212] In some examples, a fifth fixing portion 573A corresponding to the first fixing portion 559A on the accommodating member 550 may be provided on the first connecting piece 571 , and a sixth fixing portion 573B corresponding to the second fixing portion 559B on the accommodating member 550 may be provided on the second connecting piece 572 .

[0213] In some examples, the outside of the connecting sheet group 570 may be coated with an adhesive material, and during the installation of the switch assembly 500, the connecting sheet group 570 may be used to interconnect the switch assembly 500 with other components (eg, a bracket, etc.).

[0214] The fifth fixing portion 573A can cooperate with the first fixing portion 559A, and the sixth fixing portion 573B can cooperate with the second fixing portion 559B. These two groups of fixing portions can jointly realize the fixed connection between the bracket 600 and the switch assembly 500.

[0215] In some examples, the first fixing portion 559A, the second fixing portion 559B, the fifth fixing portion 573A, and the sixth fixing portion 573B may all be convex structures having the same shape and size.

[0216] In some examples, the first fixing portion 559A, the second fixing portion 559B, the fifth fixing portion 573A, and the sixth fixing portion 573B may all be concave structures having the same shape and size.

[0217] In some examples, one of the two groups of fixing structures, the first fixing portion 559A and the fifth fixing portion 573A, and the second fixing portion 559B and the sixth fixing portion 573B, may be a concave structure, and the other group may be a convex structure.

[0218] One or more components that the switch assembly 500 may include are described above respectively. The following further illustrates the functional implementation of the switch assembly 500 in conjunction with a schematic diagram after the multiple components are assembled.

[0219] Fig.21 The figure shows a top view of the receiving member 550 with the terminal pair 540 installed. The first abutting portion 5430 of the first terminal 5410 is received in the first sub-slot 5511, the first contact 5444 of the first terminal 5410 is received in the third sub-slot 5521, and the connection portion between the first abutting portion 5430 and the first contact 5444 is buried in the first channel 5410 provided in the receiving member 550. The second abutting portion 5450 of the second terminal 5420 is received in the second sub-slot 5512 provided around the first sub-slot 5511, the second contact 5464 of the second terminal 5420 is received in the fourth sub-slot 5522, and the connection portion between the second abutting portion 5450 and the second contact 5464 is buried in the second channel 5550 provided in the receiving member 550.

[0220] The first terminal 5410 and the second terminal 5420 in the terminal pair 540 can both be made of conductive materials, such as copper. The receiving member 550 can be made of insulating material (or a material with a conductivity less than a preset threshold). The first terminal 5410 and the second terminal 5420 are separated by a portion of the receiving member 550. Fig.21 In the state shown, there is no electrical connection or conduction between the first terminal 5410 and the second terminal 5420 .

[0221] Fig. 22 It is a schematic diagram of the AA section of the receiving member 550 when the protective film 510 , the push rod 520 , the spring 530 and the terminal pair 540 are all installed on the receiving member 550 .

[0222] The protective film 510, the push rod 520 and the spring sheet 530 are stacked in sequence along the thickness direction of the accommodating member 550, wherein the spring sheet 530 is arranged close to the first abutting portion 5430 of the first terminal 5410. The protective film 510 is covered on the first slot body 5510, specifically, the overlapping portion 5120 of the protective film 510 can overlap the top of the first slot body wall 5530, the second slot body wall 5560, the third slot body wall 5570 and the fourth slot body wall 5580 of the first slot body 5510. The top 5110 of the protective film 510 facing the first slot body 5510 (the inner surface) can abut against the side (the first contact surface) of the push rod 520 facing the protective film 510, and the push rod 520 can be partially accommodated in the top 5110 of the protective film 510. The side (second contact side) of the push rod 520 away from the protective film 510 may abut against the side of the pressing portion 5310 of the spring 530 facing the push rod 520, or in other words, the push rod 520 may be supported on the pressing portion 5310 of the spring 530. The supporting portion (including the first supporting portion 5320 and the second supporting portion 5330) of the spring 530 may be supported on the first boss 5533 and / or the step portion 5534.

[0223] When no external force is applied, the pressing portion 5310 of the spring sheet 530 does not contact the first abutting portion 5430. In some examples, when no external force is applied, the supporting portion of the spring sheet 530 does not contact the second abutting portion 5450.

[0224] Fig.23 for Fig. 22 The first mass point P1 on the pressing portion 5310 of the spring 530 facing the first abutting portion 5430 and the second mass point P2 on the supporting portion of the spring 530 close to the second abutting portion 5450 are taken as research objects to examine the changes of the switch assembly 500 from the beginning of the force to the removal of the external force.

[0225] Exemplarily, when the user presses the switch assembly 500, an external force F perpendicular to the thickness direction of the switch assembly 500 can act on the top 5110 of the protective film 510. Since the protective film 510, the push rod 520 and the spring 530 abut against each other, the external force F can act on the pressing portion 5310 of the spring 530 via the interaction between the protective film 510 and the push rod 520 and the interaction between the push rod 520 and the spring 530.

[0226] As mentioned above, there is an angle between the plane where the support part of the spring sheet 530 is located and the plane where the pressing part 5310 is located, and the spring sheet 530 can be made of a material with a certain elastic modulus. In this way, when the external force F acts on the pressing part 5310, the pressing part 5310 of the spring sheet 530 will deform to a certain extent, and the distance between the first particle P1 located on the side of the pressing part 5310 facing the first abutting part 5430 and the first abutting part 5430 will be shortened until the first particle P1 is displaced △x along the negative direction of the X-axis and contacts the first abutting part 5430, and the first terminal 5410 and the spring sheet 530 are connected. After the external force is removed, the spring sheet 530 gradually recovers its deformation, the first particle P1 is separated from the first abutting part 5430, and the distance between the two gradually increases until the first particle P1 returns to the initial position where the deformation of the spring sheet 530 is zero.

[0227] In some examples, when no external force is applied, the support portion of the spring sheet 530 contacts the second abutment portion 5450, and the spring sheet 530 is electrically connected to the second terminal 5420. When an external force F acts on the pressing portion 5310, the support portion of the spring sheet 530 and the second abutment portion 5450 still maintain contact with each other.

[0228] In some examples, when no external force is applied, the support portion of the spring sheet 530 contacts the first boss 5533 and the step portion 5534, or in other words, the support portion of the spring sheet 530 does not contact the second abutting portion 5450, and the spring sheet 530 is not in an electrically connected state with the second terminal 5420. When the external force F acts on the pressing portion 5310, the second mass point P2 on the support portion of the spring sheet 530 close to the second abutting portion 5450 moves toward the direction close to the second abutting portion 540 until the second mass point P2 contacts the second abutting portion 5450 after displacement △z along the positive direction of the Z axis, and the second terminal 5420 is connected with the spring sheet 530. After the external force is removed, the spring sheet 530 gradually recovers its deformation, the second mass point P2 separates from the second abutting portion 5450, and the distance between the two gradually increases until the second mass point P2 returns to the initial position where the deformation of the spring sheet 530 is zero.

[0229] As described above, under the action of external force, the spring sheet 530 will be deformed, thereby causing the spring sheet 530 to be connected to the first terminal 5410. The spring sheet 530 and the second terminal 5420 can be in a conductive state without being affected by external force, or can be connected after being deformed by external force. In this way, under the action of external force, the spring sheet 530 can be connected to the first terminal 5410 and the second terminal 5420 at the same time, that is, the first terminal 5410 and the second terminal 5420 are electrically connected.

[0230] By increasing the travel of the spring 530 in the thickness direction of the switch assembly 500 during the deformation process, the pressing feedback effect of the switch assembly 500 can be improved to a certain extent. Fig.24 Shown Fig. 22 The schematic diagram of the region C1 only includes the spring 530, the first terminal 5410 and the second terminal 5420. The first contact portion 5430 of the first terminal 5410 close to the spring 530 can be called a first contact surface 5433, and the second contact portion 5450 of the second terminal 5420 close to the spring 530 can be called a second contact surface 5453.

[0231] In order to illustrate the relative distances between the first abutting surface 5433, the second abutting surface 5453 and the elastic sheet, any reference point R0 ( Fig.24 The vertical distance between the highest point on the top surface of the spring piece 530 (taking the highest point on the top surface of the spring piece 530 as an example) and the first abutting surface 5433 and the second abutting surface 5453 is the distance along the thickness direction of the switch component 500.

[0232] like Fig.24 As shown, the vertical distance between the reference point R0 and the first abutting surface 5433 is d1, and the vertical distance between the reference point R0 and the second abutting surface 5453 is d2. In some examples, d1>d2. In some examples, the difference between d1 and d2 can be greater than a preset threshold value so that the spring piece 530 can have sufficient travel space in the vertical direction during the deformation process.

[0233] Fig.25 and Fig.26 FIG. 1 is a schematic structural diagram of a bracket 600 of a key module 40 provided in an embodiment of the present application. The bracket 600 includes a first bracket 610 and a second bracket 620 .

[0236] The second bracket 620 may include a bridge portion 6210, a first end portion 6220, and a second end portion 6230, wherein the first end portion 6220 and the second end portion 6230 are respectively connected to both ends of the bridge portion 6210. One or more connection holes may be provided on the first end portion 6220 and the second end portion 6230, and the connection holes may be matched with the connection posts on the first bracket 610. When the connection posts on the first bracket 610 are inserted into the connection holes on the second bracket 620, the first bracket 610 and the second bracket 620 may be relatively fixedly connected.

[0237] In some examples, such as Fig.26 As shown, the first end 6220 may be provided with a third extension portion 6221, and the second end 6230 may be provided with a fourth extension portion 6231.

The number of the first connection holes 6222 may match the number of the first connection columns 6121, and the number of the second connection holes 6232 may match the number of the second connection columns 6131.

[0238] Continue to refer Fig.25 and Fig.26When the first bracket 610 and the second bracket 620 are assembled or connected in accordance with one or more of the above-mentioned methods, the first bracket 610 can be placed on the third extension portion 6221 and the fourth extension portion 6231, and the inner side wall of the bridging portion 6210 of the first bracket 610 facing the second bracket 620 can be called the third abutting surface 6140, and the inner side wall of the second bracket 620 abutting against the third abutting surface 6140 of the first bracket 610 can be called the fourth abutting surface 6241. In some examples, the third abutting surface 6140 and the fourth abutting surface 6241 both include multiple curved surfaces and flat surfaces, and the shapes of the third abutting surface 6140 and the fourth abutting surface 6241 can cooperate with each other so that when the first bracket 610 is installed on the second bracket 620, the two brackets can fit as closely as possible.

[0239] The second bracket 620 further includes an exposed surface 6242 disposed opposite to the aforementioned fourth abutting surface 6241 . The exposed surface may be a plane 6242 , so as to facilitate installation in an electronic device.

[0240] Fig. 27 The figure shows an assembly diagram of the switch assembly 500 and the bracket 600. In some examples, a seventh fixing portion 6223 and an eighth fixing portion 6333 may be respectively provided on the side of the first end 6220 and the second end 6230 facing the switch assembly 500. The shapes of the seventh fixing portion 6223 and the eighth fixing portion 6333 may match the shapes of the fixing portions provided on the accommodating member 550, the support plate 560 and the connecting plate group 570 on the switch assembly 500, so as to realize a fixed connection between the switch assembly 500 and the bracket 600.

[0241] In some examples, the accommodating member 550, the supporting plate 560 and the connecting sheet group 570 on the switch assembly 500 include two convex fixing portions, and the seventh fixing portion 6223 and the eighth fixing portion 6333 on the second bracket 620 can both be as shown in FIG. Fig.26 As shown in the concave shape, the convex fixing portion on the switch assembly 500 can be clamped in the concave fixing portion on the second bracket 620 to achieve relative fixation of the second bracket 620 and the switch assembly 500.

[0242] In some examples, the accommodating member 550, the support plate 560 and the connecting plate group 570 on the switch assembly 500 include two concave fixing portions, and the seventh fixing portion 6223 and the eighth fixing portion 6333 on the second bracket 620 can both be convex, so that the convex seventh fixing portion 6223 and the eighth fixing portion 6333 on the second bracket 620 can be clamped in the concave fixing on the switch assembly 500, thereby realizing the relative fixation of the second bracket 620 and the switch assembly 500.

[0243] In some examples, a convex fixing portion and a concave fixing portion may be respectively provided at both ends of the switch assembly 500, one of the seventh fixing portion 6223 and the eighth fixing portion 6333 on the second bracket 620 may be concave and the other may be convex, and the two groups of fixing portions with matching shapes on the switch assembly 500 and the second bracket 620 can achieve relative fixation of the two.

[0244] In some examples, the first bracket 610 can be made of a material with a hardness less than or equal to the first threshold, such as silicone rubber, etc. When the first bracket interacts with the push rod 520 in the switch assembly 500, the user can press more comfortably.

[0245] In some examples, the second bracket 620 can be made of a material with a hardness greater than or equal to the second threshold, such as epoxy resin glue, structural glue, etc. The second bracket 620 can support, carry, and buffer the switch assembly 500 to a certain extent, so that the switch assembly 500 is not easily deformed or damaged under the action of external force. Here, the second threshold is greater than or equal to the aforementioned first threshold.

[0246] It should be noted that the first bracket 610 and the second bracket 620 can also be connected to each other by more methods such as gluing, and the present application does not limit this. The bracket 600 and the switch assembly 500 bracket can also be fixedly connected by more methods such as gluing, fasteners, etc., and the present application does not limit this.

[0247] Fig.28 The figure shows an adapter plate 700 provided in an embodiment of the present application. Fig.29 FIG. 5 is a schematic diagram showing the assembly method of the switch assembly 500 and the adapter plate 700 .

[0248] The adapter plate 700 may include a plug-in portion 710, a transition connection portion 720 and an external connection portion 730, wherein one end of the transition connection portion 720 is connected to the plug-in portion 710, and the other end is connected to the external connection portion 730. The plug-in portion 710 may extend from the notch provided on the switch assembly 500 into the second slot 5520, and be electrically connected to the first contact 5444 and the second contact 5464.

[0249] In some examples, the plug portion 710 is provided with a third contact 711 and a fourth contact 712, and the third contact 711 and the fourth contact 712 can be connected to the connection line inside the adapter plate 700. When the plug portion 710 is installed on the switch assembly 500, the third contact 711 and the fourth contact 712 can contact the first contact 5444 and the second contact 5464 in the switch assembly 500 respectively, that is, the electrical connection between the adapter plate 700 and the switch assembly 500 is realized.

[0250] In some examples, such as Fig.29 As shown, the switch assembly 500 may further include a clamping member 800. When the plug-in portion 710 of the adapter plate 700 extends into the second slot body 5520, the clamping member 800 is disposed between the second slot body 5520 and the plug-in portion 710. The provision of the clamping member 800 may enable the plug-in portion 710 to be more securely mounted inside the second slot body 5520. The shape and size of the clamping member 800 may be determined according to the shape and size of the second slot body 5520 on the accommodating member 550 and the shape and size of the plug-in portion 710.

[0251] Exemplarily, the clamping member 800 is in a U-shaped ring shape, and the distance h1 between the outer sides of the two arms of the clamping member 800 should be slightly smaller than the width of the notch of the second slot body 5520, so that the clamping member 800 can be accommodated in the second slot body 5520. The distance h2 between the inner sides of the two arms of the clamping member 800 should be slightly larger than the width of the plug-in portion 710, so that the plug-in portion 710 can be accommodated inside the clamping member 800.

[0252] There is a first spacing between the two ends of the transition connection part 720, and the first spacing can satisfy: when the plug-in part 710 of the adapter plate 700 extends into the second slot 5520 of the switch assembly 500, the two ends of the transition connection part 720 can be sleeved outside the receiving member 550 and the support plate 560. In other words, the first spacing should be slightly greater than the sum of the thickness of the receiving member 550 and the thickness of the support plate 560.

[0253] In some examples, the transition connection portion 720 can be an arc-shaped (rounded) bend or a right-angle bend, or in other words, the transition connection portion 720 can be a curved bend shape, or include multiple interconnected planes, and the multiple planes are inclined to each other, for example, an acute angle, a right angle, or an obtuse angle is formed between two adjacent planes.

[0254] The external connection portion 730 can be used to electrically connect to other circuit components or electronic components, for example, to connect to a circuit board that provides power to the second key module 40 .

[0255] Based on similar principles, the present application also provides Fig.30 The first combination key shown in FIG. 1 may include multiple Figure 3 The second key module shown, the adapter plates of different key modules can be connected together to a circuit that can provide power to these key modules and control signal lights.

[0256] like Fig.31 As shown, the embodiment of the present application further provides a second combination key, and the second combination key may include a Figure 3The second key module (eg, called the fifth key module) and a first key pair are shown. The adapter board of the first key pair and the adapter board of another key module can be connected together to a circuit that can provide them with power and control signal lights.

[0257] In some examples, the first key pair may include a third key module and a fourth key module, and the functional components of the third key module and the fourth key module, for example, a protective film, a push rod, a spring and a terminal pair, etc., may be accommodated in a container. The terminal pairs of the two key modules may be connected to each other and then connected to an adapter board. The first key pair may include three connection contacts, and accordingly, the adapter board corresponding to the first key pair may also be provided with three connection contacts.

[0258] The abutment parts, push rods, etc. of the terminal pair of the third key module in the first key pair can be accommodated in the first groove body of the accommodating member, the abutment parts, push rods, etc. of the terminal pair of the fourth key module can be accommodated in the second groove body of the accommodating member, and the three connecting contacts of the first key pair can be accommodated in the third groove body of the aforementioned accommodating member.

[0259] Exemplarily, the third button module and the fourth button module in the first button pair may be a “volume+” button module and a “volume-” button module respectively, and the fifth button module may be a power button module.

[0260] like Fig.32 As shown, an embodiment of the present application further provides a third combination key, and the third combination key can be composed of a sixth key module, a seventh key module and an eighth key module that share the same container. In other words, the functional components used to implement the three key modules, such as a protective film, a push rod, a spring and a terminal pair, can be accommodated in a container. The terminal pairs of the three key modules can be connected to each other and then connected to an adapter board. The third combination key can have 4 or 5 connection contacts, and accordingly, the adapter board corresponding to the third combination key can also be provided with 4 or 5 connection contacts. The adapter board of the third combination key can be used to connect a circuit that provides power, control signals, etc. for the third combination key.

[0261] The abutting parts, push rods, etc. of the terminal pairs of the three key modules of the third combination key can be respectively accommodated in three different slots of the accommodating member, and the contacts of the terminal pairs of the three key modules can be commonly accommodated in another slot of the aforementioned accommodating member. The third combination key can be provided with 4 connection contacts, 5 connection contacts, or 6 connection contacts.

[0262] Exemplarily, the sixth button module, the seventh button module and the eighth button module may be a “volume+” button module, a “volume-” button module and a power button module, respectively.

[0263] In the actual production and manufacturing process, the above-mentioned switch assembly, button module and combination button can be prepared by different processing techniques, and this application does not impose any restrictions on this.

[0264] In some examples, the preparation process of the switch assembly can first prepare the terminal pair by a stamping process, and then form a receiving part for accommodating the terminal pair, the spring sheet, the push rod, etc. by an injection molding process according to the terminal pair of a determined shape, as described above. Fig.11 As shown, one or more openings 5513 provided on the back of the container 550 near the first slot 5510 are positioning holes for the terminal pair 540 during the injection molding process, and the first protrusion 5514 provided on one side of the first notch 5523 of the container 550 is a protrusion structure corresponding to the injection port in the injection molding process. After the container is formed by injection molding, a support plate, such as a steel sheet, can be further provided on the back of the container. The spring sheet, push rod and protective film covering the top of the slot opened on the container can be further installed on the container.

[0265] The adapter plate connected to the switch assembly can be fixedly connected to the contacts of the switch assembly by laser spot welding. In some examples, in order to strengthen the connection between the adapter plate and the switch assembly, a protective medium, such as bottom filling glue, can be further filled around the contacts connecting the adapter plate and the switch assembly.

[0266] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
