Description

Technical Field

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

[0002] Currently, electronic devices such as mobile phones and tablets are equipped with key assemblies on their frames. These assemblies consist of a key body and a pressing member. The key body is designed to be pressed by the user. The pressing member is located within the electronic device and is connected to the key body. The key body and the pressing member are bonded together by an adhesive layer. When a user presses a key, the key body may become skewed when the user presses the edge of the key body, and the force applied to the key body and the pressing member may be uneven. This can cause the key body to warp and fall off relative to the pressing member, compromising the reliability of the connection between the key body and the pressing member. Summary of the Invention

[0003] The present application provides an electronic device for improving the connection reliability between a key body and a pressing member.

[0004] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0005] The present application provides an electronic device, which includes a first shell, a key assembly and a locking mechanism. The first shell has a mounting hole, the key assembly is located in the mounting hole, and the key assembly moves back and forth in a direction toward and away from the first shell. The key assembly includes a key body, a pressing member and a limiting member. The key body includes a first surface facing the interior of the first shell. The pressing member is located on the side facing the first surface. The limiting member includes a connecting portion and a limiting portion. The connecting portion has a first end and a second end opposite to each other, the first end is connected to the first surface, the second end is connected to the limiting portion, and the fixed portion is limited between the key body and the limiting portion. The locking mechanism is located in the first shell, the pressing member is connected to the locking mechanism, and the key assembly moves toward the first shell so that the pressing member triggers the locking mechanism to switch from a locked state to an unlocked state.

[0006] In this way, the key body and the pressing member are connected via a retaining member. Compared to the traditional method of connecting the key body and the pressing member solely via an adhesive layer, this method utilizes the structural features of the key assembly itself (i.e., the retaining member) to connect the key body and the pressing member. The strength of the connection between the key body and the pressing member is not affected by factors such as the material, volume, and processing method of the adhesive layer, and there is no need to add multiple steps to install the adhesive layer. This can improve the assembly efficiency between the key body and the pressing member, thereby reducing the production cost of the key assembly. Furthermore, because the key body and the pressing member are connected via a retaining member, even if the user applies force to the edge area of the key body, the key body will not fall off the surface of the fixing portion, thereby improving the reliability of the connection between the key body and the pressing member.

[0007] In a possible implementation, the pressing member includes a fixing portion having opposite second and third surfaces. The fixing portion further has a first through hole penetrating the second and third surfaces, and a part of the connecting portion is located within the first through hole. In this way, further limiting is achieved between the limiting member and the fixing portion through the cooperation of the connecting portion and the first through hole, further improving the reliability of the connection between the key body and the pressing member.

[0008] In a possible implementation, the second end is located outside the first through hole. The limiting portion includes an elastic arm having opposite third and fourth ends. The third end is connected to the second end, and the fourth end contacts the third surface. In this way, when the limiting member and the fixing portion are assembled, it is avoided that the elastic arm is stuck in the first through hole, ensuring that the elastic arm extends out of the first through hole and contacts and cooperates with the third surface to limit the fixing portion between the limiting portion and the key body.

[0009] In a possible implementation, the number of elastic arms is multiple, and the multiple elastic arms are evenly and spaced along the circumference of the connecting portion. In this way, the multiple elastic arms cooperate to jointly limit the key body and the fixing portion, further improving the reliability of the connection between the key body and the fixing portion and preventing the key body from falling off the fixing portion.

[0010] Moreover, when a user applies force to the edge of the pressing surface, compared with only setting one elastic arm, the multiple elastic arms can jointly resist the force separating the key body and the fixing portion. The force separating the two between the key body and the fixing portion is dispersed to the multiple elastic arms, and the force borne by a single elastic arm is reduced. Furthermore, the connection reliability between the elastic arm and the connecting portion is also improved, avoiding the risk of cracks occurring at the connection between the elastic arm and the connecting portion after long-term use.

[0011] In a possible implementation, the connecting portion and the limiting portion are two independent structural members. The limiting portion further includes a connecting plate connected to the second end. The connecting plate is located between the multiple elastic arms, and the third ends of the multiple elastic arms are connected to the connecting plate. In this way, compared with the limiting portion being connected to the second end through the third end, the limiting portion is connected to the connecting portion through the connecting plate, which can increase the connection area between the limiting portion and the connecting portion, thereby improving the connection stability between the limiting portion and the connecting portion.

[0012] In a possible implementation, the connecting portion is columnar, and the angle between the elastic arm and the connecting portion is greater than or equal to 45 degrees and less than or equal to 75 degrees. When the angle α2 between the elastic arm and the connecting portion is within the above range, the first through hole is for the elastic arm to pass through, and the diameter of the first through hole can be set within an appropriate range. Moreover, it can not only facilitate the deformation of the elastic arm but also ensure that the elastic arm contacts the third surface after elastic deformation and returns to its original state.

[0013] In a possible implementation, the thickness of the elastic arm is greater than or equal to 0.15 mm and less than or equal to 0.25 mm. In this way, the elastic arm has a lower limit value of 0.15 mm, and the self-structural strength of the elastic arm can be guaranteed. After multiple simulation experiments, when the thickness of the elastic arm is greater than or equal to 0.15 mm, the elastic arm can swing towards or away from the connecting part multiple times without problems such as cracks and fractures, and the stability of the elastic arm is better. The elastic arm has an upper limit value of 0.25 mm. While ensuring its own structural strength, the elastic arm also has good elasticity, which is convenient for the limiting part to pass through the first through hole when the button body is assembled with the fixing part, improving the assembly efficiency of the button assembly and reducing the production cost of the button assembly.

[0014] In a possible implementation, the fixing part includes a body and a flexible part, and the flexible part forms at least a part of the inner wall of the first through hole. The body has a second through hole, the second through hole is arranged around the flexible part, and the flexible part is spaced from the inner wall of the second through hole, and a first gap space is formed between the flexible part and the inner wall of the second through hole, and a second gap space is formed between the flexible part and the connecting part. When the button assembly is assembled, the limiting part enters the first through hole, and the elastic arm abuts against the inner wall of the first through hole, that is, the elastic arm abuts against the surface of the flexible part. Since the flexible part itself has elasticity, the flexible part can undergo elastic deformation under the abutment of the elastic arm, and the flexible part can expand and contract towards the second gap space to achieve elastic deformation. The deformation of the flexible part is a space for the limiting part to pass through the first through hole, thereby facilitating the limiting part to pass through the first through hole and improving the assembly efficiency of the limiting part.

[0015] In a possible implementation, at least a part of the limiting part is in contact with the flexible part. In this way, the length of the elastic arm can be designed to be the length that can contact the first area after popping out of the first through hole. The length of the elastic arm does not need to be designed too long. During the assembly of the button assembly, the elastic deformation of the elastic arm is small, which is convenient for the assembly of the limiting part, thereby improving the assembly efficiency of the button assembly and reducing the production cost of the button assembly.

[0016] In a possible implementation, the flexible part includes an opposite first flexible part and a second flexible part, the first through hole is formed between the first flexible part and the second flexible part, and the first flexible part and the second flexible part are symmetrically arranged with respect to the connecting part. In this way, the structural complexity of the flexible part is reduced, which is convenient for the processing of the fixing part.

[0017] In a possible implementation, the fixing part also has a first connecting part and a second connecting part, and the stiffness of the first connecting part and the second connecting part is greater than the stiffness of the flexible part. Along the circumferential direction of the first through hole, the first connecting part, the first flexible part, the second connecting part, and the second flexible part are connected in sequence, and the first connecting part and the second connecting part are also connected to the body.

[0018] In this way, the main body and the flexible part can be designed as an integral structural member. The forming process of the fixing part can be as follows: providing a blank sheet for the fixing part and performing numerical control milling on the blank sheet, that is, milling a first through hole and a second through hole on the blank sheet. The first connecting part and the second connecting part are part of the formed main body. The fixing part is designed as an integral structural member, with a simple structure. The components in the fixing part can be used without assembly, reducing the production cost of the button assembly.

[0019] In a possible implementation, the first direction of the button assembly is the direction towards the inside of the first housing and away from the inside of the first housing. In the direction perpendicular to the first direction, the distance from the flexible part to the inner wall of the second through hole is the first distance, and the first distance is greater than or equal to 0.3 mm and less than or equal to 0.5 mm. In this way, the first through hole can provide sufficient space for the through hole of the limiting part, facilitating the passage of the limiting part through the first through hole, and thus facilitating the assembly of the button assembly.

[0020] In a possible implementation, in the direction perpendicular to the first direction, the distance from the flexible part to the connecting part is the second distance, and the second distance is greater than or equal to 0.3 mm and less than or equal to 0.5 mm. In this way, the first through hole can provide sufficient space for the through hole of the limiting part, facilitating the passage of the limiting part through the first through hole, and thus facilitating the assembly of the button assembly. Similarly, the flexible part can also provide sufficient deformation space for the deformation of the elastic arm, further facilitating the passage of the limiting part through the first through hole, making the assembly of the button assembly faster, and thus reducing the production cost of the button assembly.

[0021] In a possible implementation, in the direction perpendicular to the first direction, the thickness of the flexible part is greater than or equal to 0.2 mm and less than or equal to 0.6 mm. When the thickness of the flexible part is within the above range, the flexible part can not only have sufficient structural strength, but also provide good deformation for the passage of the limiting part, providing space for the limiting part to pass through the first through hole, thus facilitating the assembly of the button assembly and reducing the production cost of the button assembly.

[0022] In a possible implementation, in the direction perpendicular to the first direction, the width of the connecting part is greater than or equal to 0.3 mm and less than or equal to 0.5 mm. When the width of the connecting part is within the above range, the connecting part itself has sufficient structural strength, and the connecting part can provide stable connection strength for the connection between the button main body and the pressing part. Moreover, the diameter of the first through hole for accommodating the connecting part does not need to be set too large, and the fixing part also has sufficient structural strength.

[0023] In a possible implementation, the number of the limiting members is multiple and spaced apart, and the number of the first through holes is equal to and corresponds one by one to the number of the limiting members. In this way, the key body and the pressing member are connected by multiple limiting members, further improving the reliability of the connection between the key body and the pressing member. When the user presses the key body, the user applies force to any edge area of the pressing surface. The multiple limiting members provide a large connection strength and all-round limitation for the key body and the pressing member, further preventing the key body from falling off the pressing member, and thus improving the reliability of the connection between the key body and the pressing member.

[0024] In a possible implementation, the multiple limiting members are distributed in a circular array relative to the connecting portion. In this way, the multiple limiting members are evenly distributed between the key body and the pressing member. The multiple limiting members provide uniform limitation for the connection between the key body and the pressing member to ensure all-round limitation of the key body and the pressing member. When the user presses the pressing surface, no matter where the user presses on the pressing surface, the multiple limiting members can provide limitation for the key body and the pressing member to ensure that the key body does not fall off the surface of the pressing member, and thus improve the reliability of the connection between the key body and the pressing member.

[0025] In a possible implementation, the number of the limiting members is two, and the two limiting members are symmetrically arranged relative to the connecting portion. Each limiting member has two elastic arms. The arrangement direction of the two elastic arms of one limiting member is the second direction, and the arrangement direction of the two elastic arms of the other limiting member is the second direction. There is an included angle between the first direction and the third direction. In this way, the first limiting member and the second limiting member form stable limitation for the key body and the pressing member, and the number of the limiting members is appropriate, which can not only ensure the connection reliability between the key body and the pressing member, but also reduce the overall production cost of the key assembly.

[0026] In a possible implementation, the second direction is perpendicular to the third direction. In this way, the elastic arms in one limiting portion can resist more stress in the first direction, and the elastic arms in the other limiting portion can resist more stress in the second direction. Therefore, the limiting members provide limitation for the key body and the fixing portion in all directions, preventing the key body from falling off the fixing portion.

[0027] In a possible implementation, the key assembly further includes an adhesive layer. The adhesive layer is a double-sided adhesive. The adhesive layer is located between the fixing portion and the key body, and is bonded to the first surface and the second surface. In this way, the key body and the pressing member are connected by the limiting members and the adhesive layer. The limiting members and the adhesive layer provide sufficient connection strength for the key body and the pressing member, improving the reliability and stability of the connection between the key body and the pressing member.

[0028] In a possible implementation, the elastic arm and the connecting plate are an integral structural member. There is also a high connection strength between the elastic arm and the connecting plate. That is to say, the elastic arm is connected to the connecting portion by means of the connecting plate, ensuring the structural reliability of the limiting portion itself and also the connection reliability between the limiting portion and the connecting portion.

[0029] In a possible implementation, the material of the limiting member is metal or hard plastic, which facilitates the deformation of the elastic arm during the assembly of the button assembly, thereby improving the assembly efficiency of the button assembly.

[0030] In a possible implementation, the material of the limiting member is aluminum, copper, steel, 5-series aluminum alloy, 6-series aluminum alloy, copper alloy or steel alloy. The 6-series aluminum alloy has high strength, and the elastic arm has good machining performance, high toughness and high strength. The yield strength of the 5-series aluminum alloy is between 160 and 250 Mpa, the elongation rate > 5%, and the average value is above 7-9%. The 5-series aluminum alloy has a low density, high tensile strength and elongation rate, which facilitates the deformation of the elastic arm.

[0031] In a possible implementation, the electronic device further includes a second housing. The pressing member further includes a pressing column, the pressing column is connected to the third surface, and the pressing column is connected to the locking structure mechanism. The button assembly moves towards the inside of the housing relative to the housing, so that the pressing column triggers the locking mechanism to switch from the self-locking state to the unlocking state. In the unlocking state, the first housing and the second housing can rotate relative to each other.

[0032] In a possible implementation, the locking mechanism includes a buckle and a transmission structure. One end of the transmission structure is connected to the pressing column, and the other end of the transmission structure is connected to the buckle. A card slot for inserting the buckle is formed on the second housing. When the buckle is located in the card slot, the first housing and the second housing are in the locked state. When the button body is pressed and moves towards the inside of the first housing, the pressing column drives the transmission structure to move in a direction perpendicular to the pressing direction, so that the transmission structure drives the buckle to withdraw from the card slot, and the first housing and the second housing are in the unlocked state.

[0070] The embodiments of the present application provide an electronic device. The electronic device includes, but is not limited to, a foldable electronic device. The foldable electronic device can include various electronic devices having a flexible screen and capable of changing the unfolded or folded form of the flexible screen and itself. For example, it can include mobile phones, tablet computers, laptop computers, e-book readers, cameras, wearable devices, household electronic devices, etc. For the sake of easy understanding, in the embodiments of the present application, the electronic device is described by taking a foldable mobile phone as an example.

[0071] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic structural diagram of the electronic device 100 provided by some embodiments of the present application when in a closed state; Figure 2The figure is a schematic structural diagram of the electronic device 100 provided by some embodiments of the present application when in the unfolded state. For different usage requirements, the foldable electronic device 100 can be unfolded to a flat state or folded to a closed state. That is to say, the foldable electronic device 100 has at least two states, namely the flat state and the closed state. In some cases, it may further include a third state, that is, an intermediate state between the flat state and the closed state. It can be understood that the intermediate state does not have only a unique state and can be any one or more states between the flat state and the closed state of the electronic device 100.

[0072] Please continue to refer to Figure 1 and Figure 2 As shown in FIGS. and, the electronic device 100 may include a rotating shaft mechanism 10, a first housing 20, and a second housing 30. Among them, the first housing 20 and the second housing 30 are disposed on opposite sides of the rotating shaft mechanism 10 and are respectively connected to the rotating shaft mechanism 10. The rotating shaft mechanism 10 can move to relatively fold or relatively unfold the first housing 20 and the second housing 30.

[0073] The first housing 20 and / or the second housing 30 may respectively form an installation space for installing electronic components such as a circuit board, a battery, a receiver, a speaker, and a camera of the electronic device 100. The first housing 20 has a first support surface 201 and a third support surface 202 disposed opposite to the first support surface 201, and the second housing 30 has a second support surface 301 and a fourth support surface 302 disposed opposite to the second support surface 301.

[0074] The electronic device 100 may further include a flexible screen 40. The flexible screen 40 can be used to display information and provide an interaction interface for users. The flexible screen 40 is disposed on the first housing 20 and the second housing 30 as a display device. Specifically, the flexible screen 40 may be disposed on the first support surface 201 and the second support surface 301. That is, when the first housing 20 and the second housing 30 are in the closed state, the flexible screen 40 is still visible to the user, and the user can also perform some operations on the flexible screen 40 in the closed state. Such an electronic device 100 is a foldable electronic device 100 with an outward folding method. Similarly, the flexible screen may also be disposed on the third support surface 202 and the fourth support surface 302. In this way, both sides of the electronic device 100 have flexible screens.

[0075] When the first housing 20 and the second housing 30 are in the closed state, the first housing 20 and the second housing 30 need to be relatively fixed and will not rotate relative to the rotating shaft mechanism 10, so as to maintain the closed state. After the first housing 20 and the second housing 30 are relatively fixed, the portability of the mobile phone can be improved.

[0076] Please refer to Figure 2 andFigure 3 , Figure 3 is Figure 2 an exploded view of the locking mechanism 50 and the button assembly 60 in the electronic device 100 shown. To achieve the structural stability of the electronic device 100 when the first housing 20 and the second housing 30 are in a closed state, the electronic device 100 of the present application further includes a locking mechanism 50 and a button assembly 60. In the locked state, the locking mechanism 50 can relatively fix the first housing 20 and the second housing 30 in the closed state and maintain the locked state; in the unlocked state, the locking mechanism 50 can unlock the locked first housing 20 and second housing 30 so that the first housing 20 and the second housing 30 can rotate relative to the rotating shaft mechanism 10. The button assembly 60 is used to drive the locking mechanism 50 to switch between the locked state and the unlocked state.

[0077] The locking mechanism 50 and the button assembly 60 can be provided on the first housing 20, or can be provided on the second housing 30. Whether the locking mechanism 50 and the button assembly 60 are provided on the first housing 20 or on the second housing 30, their working principles are the same. Below, an example will be given with the locking mechanism 50 and the button assembly 60 provided on the first housing 20 for illustration.

[0078] Please continue to refer to Figure 2 , in some embodiments, at least a part of the first housing 20 forms a support frame 203, and the support frame 203 is used to arrange the button assembly 60 and the locking mechanism ( Figure 2 not shown in the figure), that is, the support frame 203 serves as the support structure for the button assembly 60 and the locking mechanism. An installation cavity ( Figure 2 not shown in the figure) can be formed inside the support frame 203, and the locking mechanism is arranged in the installation cavity. Specifically, the support frame 203 has a wall plate 2032, and the orientation of the wall plate 2032 is the same as that of the first support surface 201. An installation hole 2031 communicating the inside and the outside of the installation cavity is provided on the wall plate 2032, and at least a part of the button assembly 60 and the locking mechanism is accommodated in the installation hole 2031.

[0079] The support frame 203 can be arranged at the end of the first housing 20 far from the rotating shaft mechanism 10. In some other embodiments, the support frame 203 can be arranged at other positions of the first housing 20. Among them, the support frame 203 and the first housing 20 can be fixedly connected by fasteners such as screws, or bonded by adhesives such as glue, or, as Figure 2 shown in the figure, is an integrally formed structure with the first housing 20.

[0080] Please refer to Figure 4 and Figure 5 , Figure 4 is Figure 2 a schematic structural diagram of the electronic device 100 when viewed from the F1 perspective;Figure 5 As shown Figure 2 in the schematic cross-sectional view taken along line B-B of the key assembly 60 and the locking mechanism 50 in the electronic device 100 shown Figure 5 The dashed line in which is a schematic diagram of the second housing 30

[0081] The locking mechanism 50 includes a transmission structure 53 and a buckle 52. The key assembly 60 is in transmission connection with the transmission structure 53. A card slot 521 for the buckle 52 to insert is provided on the second housing 30. When the buckle 52 cooperates with the card slot 521, the first housing 20 and the second housing 30 are clamped, so that the electronic device 100 is in a locked state

[0082] Please continue to refer to together Figure 4 and Figure 5 , when pressing the key assembly 60, the buckle 52 can be driven to move through the transmission structure 53. For example, when pressing the key assembly 60, the buckle 52 can move in a direction away from the second housing 30. The buckle 52 can withdraw from the card slot 521 of the second housing 30, so that the first housing 20 and the second housing 30 are in an unlocked state, so as to realize that any one of the first housing 20 and the second housing 30 can rotate around the rotating shaft mechanism 10; and when releasing the pressing force on the key assembly 60, the buckle 52 can move in a direction towards the second housing 30, and the buckle 52 can be inserted into the card slot 521 of the second housing 30, so that the first housing 20 and the second housing 30 are in a locked state, realizing the relative fixation of the first housing 20 and the second housing 30

[0083] Please continue to refer to Figure 5 , for the aesthetic appearance of the locking mechanism 50, the locking mechanism 50 further includes a decorative member 55. The decorative member 55 is arranged around the inner wall of the mounting hole 101, and the decorative member 55 is connected to the first housing 20

[0084] The structure of the key assembly 60 will be introduced in detail below. Please continue to refer to Figure 4 and Figure 5 , the key assembly 60 includes a key body 61 and a pressing member 62. The key body 61 is accommodated in the mounting hole. The key body 61 includes a pressing surface 611 and a first surface 612 which are arranged opposite to each other. The pressing surface 611 faces the outside of the mounting cavity, and the first surface 612 faces the inside of the mounting cavity. The pressing surface 611 can be a flat surface, or an arc surface with a concave center area compared with the edge area, so that when the user presses the key body 61, the force can be applied more accurately to the center area of the pressing surface 611

[0085] The pressing member 62 is located on the side of the key body 61 facing the inside of the installation cavity. The pressing member 62 may include a fixing portion 621 and a pressing column 622. The fixing portion 621 may be plate-shaped, and the cross-sectional shape of the fixing portion 621 may be circular, square, oval or irregular. The pressing member 62 is connected to the first surface 612 by means of the fixing portion 621. The pressing column 622 is connected to the surface of the fixing portion 621 facing away from the first surface 612. The pressing column 622 is used for driving connection with the transmission structure to drive the locking mechanism to switch between the locked state and the unlocked state. The fixing portion 621 and the pressing column 622 may be an integral structural member.

[0086] Please refer to Figure 5 and Figure 6 , Figure 6 for Figure 5 the schematic structural diagram of the key assembly 60 and the locking mechanism when in the second position as shown. Figure 5 and Figure 6 The dashed line in Figure 5 is the schematic diagram of the second housing. When the key body 61 is in the natural state, that is, the state when the key body 61 is not subjected to a pressing force, the key body 61 is located at the first position, that is, Figure 6 the position W1 in Figure 6 . When the key body 61 is subjected to a pressing force, it moves inward to the second position along the pressing direction, that is,

[0087] Please refer to Figure 7 , Figure 7 for Figure 6 a schematic structural diagram of the key assembly 60 as shown. In some embodiments, the key assembly 60 further includes an adhesive layer 64. The adhesive layer 64 is disposed between the key body 61 and the pressing member 62, and the key body 61 and the pressing member 62 are connected by the adhesive layer 64.

[0088] The user switches the locking state and the unlocking state of the electronic device 100 by pressing the key body 61. When the pressing area of the user is opposite to the central area Q1 of the key body 61, the force applied by the user to the key body 61 can be more evenly transmitted to the pressing member 62.

[0089] Please refer to Figure 8 , Figure 8 for Figure 7Schematic structural diagram of the shown key assembly 60 as viewed from the F2 perspective. The "central region Q1 of the key body 61" refers to the region on the key body 61 opposite to the pressing member 62. That is to say, in the arrangement direction of the key body 61 and the pressing member 62, the projection of the pressing member 62 on the key body 61 coincides with the central region Q1. According to the definition of the "central region Q1 of the key body 61", the "edge region Q2 of the key body 61" can be understood as the region on the key body 61 located outside the central region Q1.

[0090] Please continue to refer to Figure 8 , when the force application area of the user is offset relative to the central region Q1 of the key body 61, that is, when the force application area of the user is more distributed in the edge region Q2 of the key body 61, please refer to Figure 9 , Figure 9 is a schematic structural diagram of the key assembly 60 provided by some embodiments of the present application when subjected to Figure 8 the pressing force shown in. The key assembly 60 is prone to skewing problems under the force application of the user. And, in this case, the key body 61 is prone to problems of local stress and local non-stress. Taking the fixing part 621 as the fulcrum, the non-stressed part of the key body 61 is prone to warping problems, and the key body 61 and the pressing member 62 will have a debonding problem at the B region, thereby reducing the connection strength between the key body 61 and the pressing member 62, resulting in the problem of the key body 61 falling off.

[0091] Moreover, the assembly process of the key body 61 and the pressing member 62 is relatively complex. To elaborate, in the assembly of the key body 61 and the pressing member 62, first, the first surface 612 of the key body 61 and the surface of the pressing member 62 facing the key body 61 need surface treatment to ensure that the adhesive layer 64 can be combined with the key body 61 and the pressing member 62. Glue is applied to the surface of the key body 61 and / or the surface of the pressing member 62 through a dispensing process to form a liquid colloid. After the dispensing is completed, the key body 61, the liquid colloid, and the pressing member 62 are subjected to pressure holding and curing treatments to form the adhesive layer 64 to ensure better combination of the adhesive layer 64 with the key body 61 and the pressing member 62.

[0092] In summary, connecting the key body 61 and the pressing member 62 through the adhesive layer 64 formed by dispensing will result in unstable connection, leading to the problem of the key body 61 falling off. Moreover, the adhesive layer 64 formed by the dispensing process makes the assembly process of the key body 61 and the pressing member 62 relatively complex and the production cost relatively high.

[0093] To solve the above problems, some embodiments of the present application also provide a key assembly 60. Please refer to Figure 10 , Figure 10Schematic diagram of the button assembly 60 provided by some embodiments of the present application. In addition to the button body 61 and the pressing member 62 described above, the button assembly 60 further includes a limiting member 63. The structural features of the button body 61 are the same as those of the button body 61 in the above embodiments, and will not be described in detail here. On the basis of the above, the fixing portion 621 has opposite second surface 6211 and third surface 6212, wherein the second surface 6211 is connected to the first surface 612. The fixing portion 621 further has a first through hole 6213 penetrating the second surface 6211 and the third surface 6212, and the cross-sectional shape of the first through hole 6213 can be circular, square, oval, irregular, etc.

[0094] Please refer to Figure 11 , Figure 11 Schematic diagram of the limiting member 63 provided by some embodiments of the present application. The limiting member 63 includes a connecting portion 631 and a limiting portion 632. A part of the connecting portion 631 is located inside the first through hole 6213, and another part of the connecting portion 631 is located outside the first through hole 6213. The connecting portion 631 can be rod-shaped, columnar, etc. The connecting portion 631 has opposite first end 6311 and second end 6312. In this embodiment, it is described by taking both the first end 6311 and the second end 6312 being located outside the first through hole 6213 as an example. The first end 6311 is located outside the first through hole 6213, and the connecting portion 631 is connected to the first surface 612 by means of the first end 6311. The limiting portion 632 is connected to the second end 6312, and the fixing portion 621 is limited between the button body 61 and the limiting portion 632. In some embodiments, the button body 61, the connecting portion 631, and the limiting portion 632 can be an integral structural member. In some other embodiments, the button body 61 and the connecting portion 631 can also be connected by welding, threaded connection, etc.

[0095] In this way, the button body 61 and the pressing member 62 are connected by the limiting member 63. Compared with the traditional method of connecting the button body 61 and the pressing member 62 through the glue layer 64 formed by dispensing, the button body 61 and the pressing member 62 are connected through the structural features of the button assembly 60 itself (i.e., the limiting member 63). The connection strength between the button body 61 and the pressing member 62 will not be affected by factors such as the material, volume, and process method of the glue layer 64, and there is no need to add multiple processes for dispensing to form the glue layer 64, which can improve the assembly efficiency between the button body 61 and the pressing member 62, and thus reduce the production cost of the button assembly 60. Moreover, the button body 61 and the pressing member 62 are connected by the limiting member 63. Even if the user applies force to the edge area Q2 of the button body 61, the button body 61 will not fall off from the surface of the fixing portion 621, thereby also improving the reliability of the connection between the button body 61 and the pressing member 62.

[0096] In some other embodiments, the first through hole 6213 may not be provided on the fixing portion 621. The limiting member 63 may be provided on the outer peripheral edge of the fixing portion 621, and the limiting portion 632 contacts the third surface 6212 of the fixing portion 621 to limit the fixing portion 621 between the key body 61 and the limiting portion 632.

[0097] To ensure the reliability of the connection between the key body 61 and the pressing member 62, the number of the limiting members 63 may be multiple, and the number of the first through holes 6213 is equal to and corresponds to the number of the limiting members 63 one by one. In this way, the key body 61 and the pressing member 62 are connected by multiple limiting members 63, further improving the reliability of the connection between the key body 61 and the pressing member 62. When the user presses the key body 61, the user applies force to any edge area Q2 of the pressing surface 611. The multiple limiting members 63 provide a large connection strength and all-round limitation for the key body 61 and the pressing member 62, further preventing the key body 61 from falling off the pressing member 62, and thus improving the reliability of the connection between the key body 61 and the pressing member 62.

[0098] Please refer to Figure 12 , Figure 12 For Figure 10 a schematic structural view of the pressing member 62 as viewed from the F3 perspective shown. In some embodiments, the multiple limiting members 63 are distributed in a circular array relative to the connecting portion 631. "Circular array" means that the multiple limiting members 63 are evenly and spacedly distributed on the third surface 6212 around the connecting portion 631 at equal angles. The angle α1 between two adjacent limiting members 63 to the geometric center of the fixing portion 621 may be 20 degrees, 40 degrees, 60 degrees, 80 degrees, 90 degrees, 120 degrees, 150 degrees, 180 degrees, etc.

[0099] In this way, the multiple limiting members 63 are evenly distributed between the key body 61 and the pressing member 62. The multiple limiting members 63 provide uniform limitation for the connection between the key body 61 and the pressing member 62 to ensure all-round limitation of the key body 61 and the pressing member 62. When the user presses on the pressing surface 611, no matter where the user presses on the pressing surface 611, the multiple limiting members 63 can provide limitation for the key body 61 and the pressing member 62 to ensure that the key body 61 does not fall off the surface of the pressing member 62, and thus improve the reliability of the connection between the key body 61 and the pressing member 62.

[0100] The following takes the number of the limiting members 63 being two as an example for illustration. Please refer to Figure 13 , Figure 13 For Figure 10Another schematic structural view of the pressing member 62 as viewed from the F3 perspective. That is, the plurality of limiting members 63 include a first limiting member 633 and a second limiting member 634. The first limiting member 633 and the second limiting member 634 are symmetrically arranged with respect to the connecting portion 631, that is, the first limiting member 633 and the second limiting member 634 are symmetrically arranged with respect to the central axis of the connecting portion 631. It can also be understood that the first limiting member 633 and the second limiting member 634 are annularly arrayed with respect to the connecting portion 631. The included angle α1 between the line connecting the first limiting member 633 to the connecting portion 631 and the line connecting the second limiting member 634 to the connecting portion 631 is 180 degrees.

[0101] In this way, the first limiting member 633 and the second limiting member 634 form stable limiting for the key body 61 and the pressing member 62. Moreover, the number of the limiting members 63 is appropriate, which can not only ensure the connection reliability between the key body 61 and the pressing member 62, but also reduce the overall production cost of the key assembly 60. In the following text, the case where the number of the limiting members 63 is two is taken as an example for illustration.

[0102] The following is a detailed introduction to the limiting member 63. The fixing portion 621 is limited between the limiting portion 632 and the key body 61.

[0103] In some embodiments, the key body 61 and the limiting member 63 can be designed as an integral structural member. Specifically, the key body 61 can be an integral structural member with the connecting portion 631, and the connecting portion 631 and the limiting portion 632 can also be an integral structural member. The connecting portion 631 and the limiting portion 632 can also be two independent structural members. In this case, the connecting portion 631 and the limiting portion 632 can be connected by welding. When the key body 61 and the limiting member 63 are an integral structural member, the key body 61 and the limiting member 63 can be produced by one process. For example, they are produced in the same process of mold processing and forming. In this way, the production process of the key assembly 60 is more streamlined, further improving the production efficiency of the key assembly 60 and thus reducing the production cost of the key assembly 60.

[0104] For the convenience of assembling the key assembly 60, please refer to Figure 14 , Figure 14 For Figure 10Another enlarged view of the C region shown. The limiting part 632 includes an elastic arm 6321. The elastic arm 6321 includes a third end 6321a and a fourth end 6321b that face each other. The third end 6321a is connected to the second end 6312. The fourth end 6321b of the elastic arm 6321 can swing in the direction close to or away from the connecting part 631 with the third end 6321a as a fulcrum. The elastic arm 6321 can undergo elastic deformation under the action of force. In some embodiments, the material of the elastic arm 6321 is metal or hard plastic. Specifically, the material of the elastic arm 6321 can be aluminum, copper, steel, five-series aluminum alloy, six-series aluminum alloy, copper alloy or steel alloy. The six-series aluminum alloy has high strength, and the elastic arm 6321 has good processing performance, high toughness and high strength. The yield strength of the five-series aluminum alloy is between 160 and 250 Mpa, the elongation rate > 5%, and the average value is above 7 - 9%. The five-series aluminum alloy has a low density, high tensile strength and elongation rate, which is convenient for the deformation of the elastic arm 6321.

[0105] Please refer to Figure 15 , Figure 15 is Figure 14 the process flow chart of the assembly of the key body 61 and the pressing member 62 shown. In the assembly of the key assembly 60, first, the limiting part 632 enters the first through hole 6213 through the opening of the fixing part 621 facing the first through hole 6213. Immediately afterwards, the connecting part 631 and the limiting part 632 move down in the first through hole 6213. During the downward movement of the connecting part 631 and the limiting part 632, the elastic arm 6321 swings in the direction close to the connecting part 631 under the extrusion of the inner wall of the first through hole 6213 to accommodate itself in the first through hole 6213. Finally, after the limiting member 63 passes through the first through hole 6213, the elastic arm 6321 returns to its original state under its own elasticity, and the fourth end 6321b of the limiting part 632 contacts the third surface 6212. Therefore, the limiting part 632 is designed with the elastic arm 6321, which is convenient for the assembly of the key assembly 60, further improves the assembly efficiency of the key assembly 60, and thus reduces the production cost of the key assembly 60.

[0106] The button assembly 60 is assembled within the first housing 20. First, the pressing member 62 is assembled onto the locking mechanism 50. During the assembly of the pressing member 62, there will be a certain positional tolerance between the pressing member 62 and the mounting hole 101. After the pressing member 62 is assembled, the button body 61 is assembled onto the fixing portion 621 of the pressing member 62. The assembly of the button body 61 can absorb the positional tolerance between the pressing member 62 and the mounting hole 101, making the assembly of the button assembly 60 more precise. When the button body 61 and the pressing member 62 are assembled, in order to facilitate the elastic arm 6321 to extend out of the first through hole 6213, the second end 6312 of the connecting portion 631 is located outside the first through hole 6213, and the second end 6312 protrudes from the third surface 6212. Please refer back to Figure 15 , the vertical distance between the second end 6312 of the connecting portion 631 and the third surface 6212 is greater than or equal to 0.3 mm and less than or equal to 0.5 mm. For example, the vertical distance between the second end 6312 and the third surface 6212 can be 0.3 mm, 0.4 mm, 0.5 mm, etc. In this way, when the limiting member 63 is assembled with the fixing portion 621, it is possible to prevent the elastic arm 6321 from getting stuck in the first through hole 6213, ensuring that the elastic arm 6321 extends out of the first through hole 6213 and comes into contact and cooperation with the third surface 6212, so as to limit the fixing portion 621 between the limiting portion 632 and the button body 61.

[0107] Please refer to Figure 16 , Figure 16 is Figure 14 a schematic structural view of the elastic arm 6321 as seen from the F4 perspective. The number of elastic arms 6321 can be one or more. For example, the number of elastic arms 6321 can be one, two, three, four, etc. A plurality of elastic arms 6321 are evenly and spaced circumferentially along the connecting portion 631. That is to say, each elastic arm 6321 is arranged around the connecting portion 631, and the distance between the fourth ends 6321b of each pair of adjacent elastic arms 6321 is equal. In this way, a plurality of elastic arms 6321 cooperate to jointly limit the button body 61 and the fixing portion 621, further improving the reliability of the connection between the button body 61 and the fixing portion 621 and preventing the button body 61 from falling off the fixing portion 621.

[0108] Moreover, when a user applies force to the edge of the pressing surface 611, compared with only setting one elastic arm 6321, a plurality of elastic arms 6321 can jointly resist the force that separates the button body 61 and the fixing portion 621 from each other. The force that separates the button body 61 and the fixing portion 621 is dispersed to a plurality of elastic arms 6321, and the force borne by a single elastic arm 6321 is reduced. Furthermore, the reliability of the connection between the elastic arm 6321 and the connecting portion 631 is also improved, avoiding the risk of cracks occurring at the connection between the elastic arm 6321 and the connecting portion 631 after long-term use.

[0109] Please refer to Figure 17 , Figure 17 which is a schematic structural view of the limiting member 63 provided for some embodiments of the present application. In order to further improve the reliability of the connection between the elastic arm 6321 and the connecting portion 631, the limiting portion 632 further includes a connecting plate 635. The connecting plate 635 is connected to the second end 6312. The connecting plate 635 is located between a plurality of elastic arms 6321, and the third ends 6321a of the plurality of elastic arms 6321 are connected to the connecting plate 635. In this way, compared with the limiting portion 632 being connected to the second end 6312 through the third end 6321a, the limiting portion 632 is connected to the connecting portion 631 through the connecting plate 635, which can increase the connection area between the limiting portion 632 and the connecting portion 631, and further improve the stability of the connection between the limiting portion 632 and the connecting portion 631.

[0110] Furthermore, the elastic arm 6321 and the connecting plate 635 can be an integral structural member. In this way, there is also a high connection strength between the elastic arm 6321 and the connecting plate 635. That is to say, the elastic arm 6321 is connected to the connecting portion 631 by means of the connecting plate 635, the structural reliability of the limiting portion 632 itself is guaranteed, and the connection reliability between the limiting portion 632 and the connecting portion 631 can also be guaranteed.

[0111] In some embodiments, the connecting portion 631 is columnar, and the included angle α2 between the elastic arm 6321 and the connecting portion 631 is greater than or equal to 45 degrees and less than or equal to 75 degrees. For example, the included angle α2 between the elastic arm 6321 and the connecting portion 631 can be 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, etc. When the included angle α2 between the elastic arm 6321 and the connecting portion 631 is within the above range, the diameter of the first through hole 6213 for the elastic arm 6321 to pass through can be set within an appropriate range, and it can not only facilitate the deformation of the elastic arm 6321, but also ensure that the elastic arm 6321 returns to its original state and contacts the third surface 6212 after elastic deformation.

[0112] In some embodiments, the thickness D1 of the elastic arm 6321 is greater than or equal to 0.15 mm and less than or equal to 0.25 mm. For example, the thickness of the elastic arm 6321 can be 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm, 0.2 mm, 0.21 mm, 0.22 mm, 0.23 mm, 0.24 mm, 0.25 mm.

[0113] In this way, the elastic arm 6321 has a lower limit of 0.15 mm, ensuring the structural strength of the elastic arm 6321. After multiple simulation experiments, it was found that when the thickness of the elastic arm 6321 is greater than or equal to 0.15 mm, the elastic arm 6321 can swing multiple times toward or away from the connecting portion 631 without cracking or breaking, indicating that the elastic arm 6321 has good stability. The elastic arm 6321 has an upper limit of 0.25 mm. While ensuring its structural strength, the elastic arm 6321 also has good elasticity. This facilitates the passage of the limit member 63 through the first through hole 6213 during assembly of the key body 61 and the fixing portion 621, improving the assembly efficiency of the key assembly 60 and reducing the production cost of the key assembly 60.

[0114] See also Figure 18 , Figure 18 Schematic diagram of the structure of a fixing portion 621 provided in some embodiments of the present application. In some embodiments, the fixing portion 621 includes a body 6214 and a flexible portion 6215. The body 6214 forms the main structure of the fixing portion 621, and the flexible portion 6215 forms at least a portion of the inner wall of the first through-hole 6213. The body 6214 has a second through-hole 6216, which is arranged around the flexible portion 6215. The flexible portion 6215 is spaced apart from the inner wall of the second through-hole 6216, forming a first gap K1 between the flexible portion 6215 and the inner wall of the second through-hole 6216.

[0115] See also Figure 19 , Figure 19 for Figure 18 The diagram shows a structure in which the fixing portion 621 and the connecting portion 631 are located within the first through hole 6213. A second gap space K2 is formed between the flexible portion 6215 and the connecting portion 631. The end of the first through hole 6213 facing the key body 61 forms a first opening, and the end of the first through hole 6213 facing away from the key body 61 forms a second opening.

[0116] During assembly of the key assembly 60, the stopper 63 enters the first through-hole 6213 through the first opening, and the elastic arm 6321 abuts the inner wall of the first through-hole 6213, that is, the elastic arm 6321 abuts the surface of the flexible portion 6215. Because the flexible portion 6215 is inherently elastic, the abutment of the elastic arm 6321 causes the flexible portion 6215 to elastically deform, allowing the flexible portion 6215 to expand and contract toward the second gap K2 to achieve elastic deformation. This deformation of the flexible portion 6215 creates space for the stopper 63 to pass through the first through-hole 6213, thereby facilitating the stopper 63's passage through the first through-hole 6213 and improving assembly efficiency of the stopper 63.

[0117] In some embodiments, the flexible portion 6215 may be annular and disposed around the connecting portion 631.Figure 19 and Figure 20 In some other embodiments, the flexible portion 6215 has a plurality of spaced-apart portions. For example, the flexible portion 6215 includes an opposite first flexible portion 6215a and a second flexible portion 6215b. A first through hole 6213 is formed between the first flexible portion 6215a and the second flexible portion 6215b. The first flexible portion 6215a and the second flexible portion 6215b are symmetrically arranged with respect to the connecting portion 631. In this way, the structural complexity of the flexible portion 6215 is reduced, facilitating the machining of the fixing portion 621.

[0118] Please continue to refer to Figure 18 and Figure 19 In some embodiments, the fixing portion 621 further has a first connecting portion 6217a and a second connecting portion 6217b, and the stiffness of the first connecting portion 6217a and the second connecting portion 6217b is greater than that of the flexible portion 6215. Along the circumferential direction of the first through hole 6213, the first connecting portion 6217a, the first flexible portion 6215a, the second connecting portion 6217b, and the second flexible portion 6215b are sequentially connected, and the first connecting portion 6217a and the second connecting portion 6217b are also connected to the body 6214.

[0119] In this way, the body 6214 and the flexible portion 6215 can be designed as an integral structural member. The forming process of the fixing portion 621 can be as follows: providing a blank plate for the fixing portion 621, and performing numerical control milling on the blank plate, that is, milling the first through hole 6213 and the second through hole 6216 on the blank plate. The first connecting portion 6217a and the second connecting portion 6217b are part of the formed body 6214. The fixing portion 621 is designed as an integral structural member, and the structure of the fixing portion 621 is simple. The components in the fixing portion 621 can be used without assembly, reducing the production cost of the button assembly 60.

[0120] In some embodiments, the central axis of the first through hole 6213 is collinear with the central axis of the second through hole 6216, and the distances from each part of the flexible portion 6215 to the inner wall of the second through hole 6216 are equal everywhere. In this way, the second gap space K2 can provide sufficient deformation space for the flexible portion 6215.

[0121] Please refer to Figure 20 , Figure 20 which is a schematic structural diagram of the button assembly 60 provided by still some other embodiments of the present application. On the basis of the above embodiments, after the limiting portion 632 passes through the first through hole 6213, the elastic arm 6321 can contact the third surface 6212 on the side of the second through hole 6216 away from the connecting portion 631.

[0122] In some other embodiments, please refer to Figure 21 , Figure 21Schematic diagram of the key component 60 provided for some other embodiments of the present application. The elastic arm 6321 can also contact the first area on the third surface 6212, where the first area refers to the surface of the flexible part 6215 facing away from the key body 61. In this way, the length of the elastic arm 6321 can be designed to be the length that can contact the first area after popping out from the first through hole 6213. The length of the elastic arm 6321 does not need to be designed too long. During the assembly of the key component 60, the elastic deformation of the elastic arm 6321 is small, which is convenient for the assembly of the limiting part 632, thereby improving the assembly efficiency of the key component 60 and reducing the production cost of the key component 60.

[0123] Please continue to refer to Figure 21 , in some embodiments, in the direction perpendicular to the pressing direction, that is, in the direction of the X-axis, the width L1 of the connecting part 631 is greater than or equal to 0.3 mm and less than or equal to 0.5 mm. For example, the width L1 of the connecting part 631 can be 0.3 mm, 0.4 mm, 0.5 mm. When the width L1 of the connecting part 631 is within the above range, the connecting part 631 itself has sufficient structural strength, and the connecting part 631 can provide stable connection strength for the connection between the key body 61 and the pressing part 62. And, the diameter of the first through hole 6213 for accommodating the connecting part 631 does not need to be set too large, and the fixing part 621 also has sufficient structural strength.

[0124] Please continue to refer to Figure 21 , in order to facilitate the limiting part 632 to pass through the first through hole 6213, and when the limiting part 632 passes through the first through hole 6213, the flexible part 6215 can provide sufficient deformation space. In the direction perpendicular to the pressing direction, the distance from the flexible part 6215 to the inner wall of the second through hole 6216 is the first distance L4, and the first distance L4 is greater than or equal to 0.3 mm and less than or equal to 0.5 mm; the distance from the flexible part 6215 to the connecting part 631 is the second distance L2, and the second distance L2 is greater than or equal to 0.3 mm and less than or equal to 0.5 mm.

[0125] In this way, the first through hole 6213 can provide sufficient space for the through hole of the limiting part 632, facilitating the limiting part 632 to pass through the first through hole 6213, and thus facilitating the assembly of the key component 60. Similarly, the flexible part 6215 can also provide sufficient deformation space for the deformation of the elastic arm 6321, further facilitating the limiting part 632 to pass through the first through hole 6213, making the assembly of the key component 60 faster, and thus reducing the production cost of the key component 60.

[0126] Please continue to refer to Figure 21, in some embodiments, in the direction of the vertical pressing direction, the thickness L3 of the flexible portion 6215 is greater than or equal to 0.2 mm and less than or equal to 0.6 mm. For example, the thickness L3 of the flexible portion 6215 can be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, etc. When the thickness of the flexible portion 6215 is within the above range, the flexible portion 6215 can not only have sufficient structural strength, but also provide good deformation for the passing of the limiting portion 632, provide space for the limiting portion 632 to pass through the first through hole 6213, thereby facilitating the assembly of the button assembly 60 and reducing the production cost of the button assembly 60.

[0127] Please continue to refer to Figure 21 , on the basis of the above embodiments, the button assembly 60 may further include an adhesive layer 64. The adhesive layer 64 is located between the fixing portion 621 and the button body 61, and the adhesive layer 64 is bonded to the first surface 612 and the second surface 6211. In this way, the button body 61 and the pressing member 62 are connected through the limiting member 63 and the adhesive layer 64. The limiting member 63 and the adhesive layer 64 provide sufficient connection strength for the button body 61 and the pressing member 62, and improve the reliability and stability of the connection between the button body 61 and the pressing member 62.

[0128] In some embodiments, the adhesive layer 64 can be a double-sided adhesive tape. In this way, during the assembly of the button assembly 60, the button body 61 can be directly bonded to the pressing member 62 without going through a series of process steps such as surface treatment, dispensing, and pressure holding, thereby improving the assembly efficiency of the button assembly 60.

[0129] Please refer to Figure 22 , Figure 22 For Figure 10 FIG. is another schematic structural view of the pressing member 62 as viewed from the F3 perspective. In some embodiments, there are two elastic arms 6321 for each limiting member 63. The arrangement direction of the two elastic arms 6321 of one limiting member 63 is the first direction, and the arrangement direction of the two elastic arms 6321 of the other limiting member 63 is the second direction. There is an included angle between the first direction and the second direction. In some embodiments, the first direction is perpendicular to the second direction. Please refer to Figure 23 , Figure 23 For Figure 22 the schematic structural view of the fixing portion 621 in Figure 22 In order to adapt to

[0130] In this way, the elastic arm 6321 in one of the limiting parts 632 can resist more stress in the first direction, and the elastic arm 6321 in the other limiting part 632 can resist more stress in the second direction. Therefore, the limiting member 63 limits the key body 61 and the fixing part 621 in all directions, preventing the key body 61 from falling off the fixing part 621.

[0131] Please also refer back Figure 3 and Figure 5 , and the transmission structure 53 in the locking mechanism 50 will be introduced in detail below.

[0132] Please refer back Figure 3 , the transmission structure 53 includes a driving member 531, a driven member 532 that moves with the driving member 531, a connecting member 533 disposed between the driving member 531 and the driven member 532, and a fixing frame 535 for fixing the above-mentioned various components. The pressing member 62 in the above content forms the driving member 531 in the transmission structure 53.

[0133] Please refer to Figure 3 , the fixing frame 535 includes a first fixing frame 5351 and a second fixing frame 5352. The first fixing frame 5351 is connected to the second fixing frame 5352. The first fixing frame 5351 and the second fixing frame 5352 can be connected by threaded connectors, welding, bonding, etc. In some embodiments, the first fixing frame 5351 and the second fixing frame 5352 can also be integrally formed structural members. After the first fixing frame 5351 and the second fixing frame 5352 are installed as a whole, a receiving cavity for installing the various components of the transmission structure 53 is formed.

[0134] The first fixing frame 5351 is provided with a third through hole 5351a, and the second fixing frame 5352 is provided with a fourth through hole 5352a. The third through hole 5351a and the fourth through hole 5352a are coaxially arranged. The coaxial arrangement here means that the axis of the third through hole 5351a coincides with the axis of the fourth through hole 5352a. The coincidence here includes a coincidence with an error. That is to say, the axis of the third through hole 5351a and the axis of the fourth through hole 5352a can intersect, and the included angle between the axis of the third through hole 5351a and the axis of the fourth through hole 5352a within 30 degrees can be considered that the third through hole 5351a and the fourth through hole 5352a are coaxial.

[0135] At least a part of the driving member 531 is received in the third through hole 5351a and the fourth through hole 5352a, and the driving member 531 can reciprocate relative to the fixed frame 535 along the pressing direction. The driving member 531 includes an arc-shaped block 5311. One end of the arc-shaped block 5311 is connected to the first surface 5111 of the key body 61, and the other end of the arc-shaped block 5311 extends in a direction away from the key body 61, that is, extends toward the inside of the installation cavity, or can be said to extend toward the third through hole 5351a and the fourth through hole 5352a. The arc-shaped block 5311 has a receiving groove 5313.

[0136] Please refer to Figure 3 , the movement of the driving member 531 in the pressing direction drives the driven member 532 to move in a direction perpendicular to the pressing direction. Specifically, the driven member 532 includes a roller 5321 and a moving frame 5322 that rolls with the roller 5321. At least a part of the roller 5321 is received in the receiving groove 5313. The moving frame 5322 is provided with a groove 5355 that cooperates with the roller 5321. Both ends of the roller 5321 are embedded in the groove 5355, and the roller 5321 can roll relative to the groove 5355. The moving frame 5322 also includes a fifth through hole 5323, and at least a part of the driving frame is received in the fifth through hole 5323.

[0137] The driving member 531 moves toward the inside of the installation cavity as the key body 61 is pressed down. As the driving member 531 moves, the bottom wall of the groove of the arc-shaped block 5311 presses the roller 5321. The roller 5321 rolls under the pressing and moves in a direction perpendicular to the pressing direction to avoid the downward movement of the driving member 531. The movement of the roller 5321 drives the moving frame 5322 to move away from the arc-shaped block 5311 in a direction perpendicular to the pressing direction.

[0138] In order to ensure the direction of movement of the driven member 532, the moving frame 5322 also includes a guide shaft, and the inner wall of the accommodation cavity has a slide rail that cooperates with the guide shaft. When the moving frame 5322 moves, the cooperation between the guide shaft and the slide rail ensures that the moving frame 5322 moves in a direction perpendicular to the pressing direction to ensure the accuracy of the opening and closing of the locking mechanism 50.

[0139] The buckle 52 is connected to the end of the moving frame 5322 facing the second housing 30, and the buckle 52 and the moving frame 5322 can be an integral structural member. When the user presses the key body 61, the driving member 531 moves toward the inside of the installation cavity as the key body 61 is pressed down. The downward pressing of the driving member 531 drives the driven member 532 to move in a direction perpendicular to the pressing direction. The moving frame 5322 drives the buckle 52 to move, so that the buckle 52 is disengaged from the slot 521 on the second housing 30, realizing the unlocking of the first housing 20 and the second housing 30. The first housing 20 can be flipped relative to the second housing 30, and the second housing 30 can be flipped relative to the first housing 20.

[0140] Please continue to refer to Figure 5 Figure 5 , the locking mechanism 50 further includes an elastic reset member 534, which is disposed in the accommodating cavity and connected to the moving frame 5322. During the above unlocking process, when the moving frame 5322 moves away from the second housing 30 in a direction perpendicular to the pressing direction, the moving frame 5322 presses the elastic reset member 534. After unlocking, when the user releases the pressing force applied to the button body 61, the elastic reset member 534 presses the moving frame 5322 to move toward the second housing 30 under its own elasticity to achieve reset. The movement of the moving frame 5322 drives the driving member 531 to move upward, and the upward movement of the driving member 531 drives the button body 61 to reset.
