Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to an electronic device and a touch module. Background Art

[0002] With the development of science and technology, electronic devices have more and more functions, making electronic devices such as tablet computers and laptops widely used in people's daily life and work.

[0003] To ensure the flexibility and convenience of electronic devices, some electronic devices are equipped with keyboards and touch modules. The touch module can be used as one of the input modules of the electronic device, and the user can input operation instructions by pressing or touching. When the user inputs the operation instruction by pressing, the touch module can sense the user's pressing and provide the user with pressing feedback to increase the user's hand feel.

[0004] However, when the deformation of the existing touch module exceeds the standard, the pressing force value of the pressing feedback provided by the touch module will be too large, making the user feel poor when pressing. Summary of the invention

[0005] The present application provides an electronic device and a touch module, which can avoid the problem of excessive feedback pressure value during the manufacturing and production line assembly process of the touch module, so that the pressing force value of the touch module can be better controlled, and can also solve the problem of weak pressing spring and empty pressing when the touch module is not pressed.

[0006] A first aspect of an embodiment of the present application provides an electronic device, the electronic device comprising:

[0007] case;

[0008] A touch unit is installed in the housing, the touch unit has a touch surface, and the touch surface is exposed on the surface of the housing; the touch unit includes a touch circuit board; the touch circuit board has a first surface and a second surface in the thickness direction, and the first surface faces the touch surface;

[0009] A support member is supported on the second surface of the touch circuit board and elastically abuts against the housing; the support member has a first mounting portion;

[0010] The rotating member is connected to the first mounting portion and fixed on the shell, and the supporting member is rotatably connected to the shell through the rotating member.

[0011] The present application sets a rotating member in an electronic device. Since the rotating member is connected to the first mounting portion on the support member and fixed to the housing, and the support member is supported on the second surface of the touch circuit board, the present application can replace the lock ear of the touch module in the related art through the setting of the rotating member, so that the support member can be rotatably connected to the housing through the rotating member, and the touch module including the touch unit and the support member can be fixed on the housing through the elastic abutment of the support member and the housing. Since the support member is rotatably connected to the housing through the rotating member, and the support member is supported on the second surface of the touch circuit board, when the touch unit is pressed, the support member can move relative to the housing around the rotating member toward the inside of the housing, and drive the touch unit to move relative to the housing around the rotating member toward the inside of the housing, thereby ensuring the normal use of the press input function of the touch module.

[0012] On the basis of ensuring the normal use of the press input function of the touch module, this application replaces the lock ear with a rotating part, and also eliminates the source of the lock ear deformation on the touch module's pressing force value, thereby avoiding the problem of excessive feedback of the pressing force value during the manufacturing and production line assembly process of the touch module, so as to improve the user experience when pressing the touch module, and make the pressing force value of the touch module better controlled. In addition, by setting the rotating part, not only can the cost and weight of the touch module be reduced, but also the problem of weak pressing spring and empty pressing when the touch module is not pressed can be solved.

[0013] In some embodiments, the housing has a cavity inside, and the housing has an opening connected to the cavity; the touch unit is located in the opening so that the touch surface is exposed on the outer surface of the housing to facilitate user operation on the touch surface;

[0014] The rotating member is fixed to the inner surface of the shell so that the supporting member can be rotatably connected to the inner surface of the shell through the rotating member. While the touch unit is installed in the opening of the shell, the rotating member can be hidden in the shell to ensure the aesthetics of the electronic device.

[0015] In some embodiments, the rotating member is connected to the side wall of the first mounting portion in the thickness direction of the touch circuit board and is disposed on the inner surface of the housing, so that the rotating member can be fixed to the inner surface of the mounting shell while avoiding the rotating member occupying the space of the housing in the cavity; the thickness direction of the first mounting portion is parallel to the thickness direction of the touch circuit board;

[0016] The rotating member is fixed to the inner surface of the shell through the adapter; the rotating member is rotatably arranged between the shell and the adapter, so that the rotating member can be fixed to the inner surface of the mounting shell through the adapter and can also rotate between the shell and the adapter.

[0017] In some embodiments, the adapter is pressed onto the rotating member, the adapter is connected to the housing, and an assembly hole is formed between the adapter and the housing;

[0018] The rotating member is rotatably arranged in the assembly hole, so that the rotating member can be fixed to the inner surface of the housing through the adapter, and the rotating member can be rotatably arranged between the housing and the adapter. Moreover, through the arrangement of the assembly hole, the rotation of the rotating member between the housing and the adapter can also be restricted.

[0019] In some embodiments, the adapter has a first half hole on a surface facing the rotating member, and the inner surface of the shell has a second half hole;

[0020] When the adapter is connected to the shell, the first half hole and the second half hole form an assembly hole.

[0021] In this way, the rotating part is fixed to the inner surface of the shell through the adapter, so that the rotating part can be rotated in the assembly hole. At the same time, the thickness of the shell can be reasonably utilized to form the assembly hole with the adapter to avoid the adapter being too thick.

[0022] In some embodiments, a first groove is provided on the inner surface of the housing, the first groove is arranged corresponding to the adapter, and the adapter is located in the first groove;

[0023] The second half hole is located at the bottom of the first slot body.

[0024] In this way, the rotating member can be embedded in the bottom of the first groove body. After the adapter is pressed onto the rotating member, the adapter can also be embedded in the mounting shell in the housing, so as to realize the connection between the adapter and the housing while avoiding the further arrangement of the rotating member and the adapter, which occupies the space of the housing in the cavity.

[0025] In some embodiments, the first mounting portion has two rotating members, and along the length direction of the touch circuit board, the two rotating members are distributed on both sides of the first mounting portion;

[0026] The two rotating parts correspond to a transfer part respectively, and the two rotating parts are fixed to the inner surface of the shell through the corresponding transfer parts.

[0027] In this way, the first mounting portion can be fixed to the inner surface of the housing through two rotating members and the adapters corresponding to the two rotating members, so as to enhance the stability of the connection between the supporting member and the housing, thereby ensuring the stability of the touch module being assembled on the housing.

[0028] In some embodiments, the two adapters located at the first mounting portion are connected to each other to ensure the consistency of the rotation of the touch module around the two rotating members.

[0029] In some embodiments, the first mounting portion is a protruding structure on a side edge of the support member;

[0030] A second groove body is provided on the inner surface of the shell, the second groove body is communicated with the opening, and at least a part of the first mounting portion is located in the second groove body.

[0031] In this way, when the touch unit is installed in the opening, part of the first mounting portion can be located in the second groove body, so that the first mounting portion can be fixed in the second groove body through the rotating part and the adapter, and the first mounting portion can be embedded in the mounting shell to avoid the setting of the rotating part and the adapter occupying the space of the shell in the cavity.

[0032] In some embodiments, the number of the first mounting portions is more than two, and along the length direction of the touch unit, the more than two first mounting portions are spaced apart and arranged on the support member;

[0033] A rotating member is correspondingly mounted on each first mounting portion.

[0034] By providing more than two first mounting parts, the size of the first slot can be reduced to enhance the strength of the housing. In addition, the housing, the rotating member, and the adapter member connected to each other on the first mounting part can form more than two rotating pairs, so that when the touch unit is pressed, the touch module rotates around the rotating member.

[0035] In some embodiments, the housing has a user side and a non-user side in a width direction of the touch circuit board;

[0036] A first mounting portion is provided on a side of the support member adjacent to the non-user side, and a side of the support member adjacent to the user side is elastically abutted against the shell.

[0037] In this way, it is convenient for the user to press the touch unit on one side of the user side to realize the pressing input function of the touch module. At the same time, since the support member is elastically abutted against the shell, it is also convenient to reset the touch module.

[0038] In some embodiments, the support member includes a first support plate and a second support plate, and the first support plate and the second support plate are spaced apart from each other along a width direction of the touch circuit board;

[0039] The rotating member is located at a side of the first supporting plate away from the second supporting plate, and a side of the second supporting plate away from the first supporting plate is elastically abutted against the shell.

[0040] When the deformation degrees of the left and right sides of the upper cross beam in the shell are inconsistent, due to the interval between the first support plate and the second support plate, the second support plate is less likely to twist and deform under the drive of the touch circuit board, thereby solving the problem of increased initial step difference between the left and right sides of the touch module on the ground side and the mounting shell due to the deformation of the upper cross beam, improving the problem of poor step difference uniformity on the left and right sides of the ground side of the touch module, and also solving the problem of inconsistent pressing force values ​​on the left and right sides of the touch module.

[0041] In some embodiments, the first support plate and the second support plate are both bonded to the touch circuit board to achieve connection between the first support plate and the second support plate and the touch circuit board, so that the first support plate and the second support plate can be supported on the second surface of the touch circuit board.

[0042] In some embodiments, the interior of the housing has a protrusion protruding toward one side of the support member;

[0043] The touch circuit board has a touch switch on the second surface, and the touch switch is exposed on the side of the support away from the touch circuit board; the touch switch is constructed so that when the touch unit is pressed, it can elastically deform toward the second surface under the action of the protrusion to trigger the touch circuit board.

[0044] In this way, when the user presses the touch module, the touch unit and the support member can rotate around the rotating member toward one side of the protrusion. Under the action of the protrusion, the touch switch is elastically deformed toward one side of the touch circuit board, thereby triggering the touch circuit board to realize the press input function of the touch module. After the user's pressing force disappears, the deformation force generated by the touch switch causes the touch unit and the support member to rotate around the rotating member toward the side away from the protrusion, thereby realizing the reset of the touch module.

[0045] In some embodiments, the support member further has a second elastic member on the side facing the touch circuit board. When the touch unit is installed in the shell, the second elastic member elastically abuts against the shell and is in a pre-stressed state to eliminate the gap between the touch switch and the protrusion.

[0046] By disposing the second elastic member, the gap between the touch switch and the protruding portion can be eliminated, thereby solving the problem of empty pressing of the touch module in the related art.

[0047] In some embodiments, the second elastic member is located on one side of the support member adjacent to the touch switch, so that when the second elastic member elastically abuts against the shell, the support member and the touch circuit board can move toward one side of the protrusion to eliminate the gap between the touch switch and the protrusion.

[0048] In some embodiments, the support member has a second mounting portion, and the second mounting portion is exposed on the side of the touch circuit board;

[0049] The shell has a third slot body, and the second mounting portion is located inside the third slot body; the second elastic member is located on a side of the second mounting portion facing the touch circuit board and abuts against a slot wall of the third slot body.

[0050] By disposing the second mounting portion, the second elastic member can be assembled on the support member without affecting the installation of the touch circuit board in the opening of the mounting shell, and can be elastically abutted against the shell in the third groove.

[0051] In some embodiments, the second mounting portion is a protruding structure on the side edge of the support member, so that the second mounting portion can be located inside the third groove body, which can be beneficial to the miniaturization of the support member and the touch module.

[0052] In some embodiments, the electronic device further includes a first elastic member connected to a side of the support member away from the touch circuit board;

[0053] A support platform is provided in the shell. When the touch unit is installed on the shell, the first elastic member abuts against the support platform.

[0054] By disposing the first elastic member, elastic abutment between the support member and the shell can be achieved.

[0055] In some embodiments, the first elastic member and the first mounting portion are located on opposite sides of the support member so that a side of the support member adjacent to the user side of the housing elastically abuts against the housing to facilitate user operation on the touch module.

[0056] In some embodiments, the touch control unit further includes a cover plate, which is disposed on the first surface of the touch control circuit board to form a touch control surface.

[0057] By setting the cover plate, the touch circuit board can be prevented from being exposed on the surface of the electronic device, so as to achieve the protection function of the touch circuit board.

[0058] A second aspect of an embodiment of the present application provides a touch module, the touch module comprising:

[0059] A touch unit is configured to be mounted on a housing of an electronic device, and has a touch surface; the touch unit includes a touch circuit board; the touch circuit board has a first surface and a second surface in a thickness direction, and the first surface faces the touch surface;

[0060] A support member supported on the second surface of the touch circuit board and configured to elastically abut against the housing; the support member has a first mounting portion;

[0061] The rotating member is connected to the first mounting portion and fixed on the shell. The supporting member is constructed to be rotatably connected to the shell through the rotating member.

[0062] On the basis of ensuring the normal use of the pressing input function of the touch module, the present application can avoid the problem of excessive pressure feedback during the manufacturing and assembly of the touch module through the setting of the rotating part, so as to improve the user experience when pressing the touch module and make the pressing force value of the touch module better controlled. In addition, the setting of the rotating part can not only reduce the cost and weight of the touch module, but also solve the problem of weak pressing spring and empty pressing when the touch module is not pressed.

[0063] In some embodiments, the touch module also includes an adapter, the rotating member is fixed to the shell through the adapter, and the rotating member is rotatably arranged between the shell and the adapter, so that the rotating member can be fixed to the inner surface of the mounting shell through the adapter and can also rotate between the shell and the adapter.

[0064] In some embodiments, the support member includes a first support plate and a second support plate, and the first support plate and the second support plate are spaced apart from each other along a width direction of the touch circuit board;

[0065] The rotating member is located on a side of the first supporting plate away from the second supporting plate, and a side of the second supporting plate away from the first supporting plate is configured to elastically abut against the shell.

[0066] By setting the first support plate and the second support plate at a distance, the second support plate is less likely to be twisted and deformed under the drive of the touch circuit board, thereby solving the problem of increased initial step difference between the left and right sides of the touch module on the ground side and the mounting shell due to deformation of the upper crossbeam, improving the problem of poor step difference uniformity on the left and right sides of the touch module on the ground side, and also solving the problem of inconsistent pressing force values ​​on the left and right sides of the touch module.

[0067] In some embodiments, the support member further has a second elastic member on the side facing the touch circuit board. When the touch unit is installed on the shell, the second elastic member is constructed to elastically abut against the shell when the touch unit is installed on the shell and is in a pre-stressed state. The second elastic member is used to eliminate the gap between the touch switch and the protruding portion, thereby solving the problem of empty pressing in the touch module in the related art.

[0102] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0103] An embodiment of the present application provides an electronic device, which may include but is not limited to a laptop computer, a tablet computer (portable android device, PAD), a personal digital assistant (personal digital assistant, PDA), a handheld device with a wireless communication function, a computing device, a vehicle-mounted device, a wearable device, a virtual reality (virtual reality, VR) terminal device, an augmented reality (augmented reality, AR) terminal device, and other electronic devices with a touch module inside.

[0104] Figure 1 The schematic diagram shows a structure of an electronic device 100 in an open state. Figure 1 The electronic device 100 in the embodiment is a notebook computer. The structure of the electronic device 100 is further described below by taking the notebook computer as an example.

[0105] See also Figure 1 As shown, the electronic device 100 may include a screen component 1, a body 2 and a hinge mechanism 3. The screen component 1 is rotatably connected to the body 2 via the hinge mechanism 3. By rotating the screen component 1 relative to the body 2, the configuration of the electronic device 100 may be changed.

[0106] For example, see Figure 1 As shown, along a + When the screen member 1 is rotated in the direction such that the screen member 1 rotates around the rotating shaft mechanism 3 toward the side away from the body 2, the electronic device 100 can be opened so that the electronic device 100 is in the open state. When the electronic device 100 is in the open state, the screen member 1 is arranged at an angle with the body 2, and the display screen 12 on the screen member 1 is exposed outside the electronic device 100 and is visible to the user.

[0107] For example, when the screen member 1 is rotated along the a-direction so that the screen member 1 rotates around the rotation axis mechanism 3 toward the side close to the body 2, the electronic device 100 can be switched from the open state to the closed state. When the electronic device 100 is in the closed state, the screen member 1 is stacked on the body 2, and the display screen 12 on the screen member 1 is not exposed outside the electronic device 100 and is not visible to the user.

[0108] The hinge mechanism 3 may be located between the body 2 and the screen housing 11, so that the screen member 1 is rotatably connected to the body 2 via the hinge mechanism 3. The structure of the hinge mechanism 3 may refer to the related description of the electronic device 100 in the prior art, and will not be further elaborated here.

[0109] It should be noted that the screen component 1 and the body 2 can also be two independent structures in the electronic device 100. For example, the screen component 1 and the body 2 are detachable. When the electronic device 100 is in use, the screen component 1 can be set on the body 2, and after the electronic device 100 is used, the screen component 1 and the body 2 can be separated from each other. In this case, the screen component 1 can be a tablet computer, and the body 2 can be a keyboard of the tablet computer.

[0110] Continue to see Figure 1 In addition to the display screen 12, the screen component 1 also includes a screen shell 11. The screen shell 11 has an assembly cavity adapted to the structure of the display screen 12. The display screen 12 is assembled in the assembly cavity to form the screen component 1 together with the screen shell 11.

[0111] Continue to see Figure 1 The body 2 may include a body shell. The body shell has a cavity 214 (not shown). The circuit board of the electronic device 100 may be disposed in the cavity 214.

[0112] The body 2 may further include a keyboard 22 and a touch module 23. The keyboard 22 and the touch module 23 are both mounted on the same surface of the body shell. The keyboard 22, as an input module on the body 2, may be electrically connected to the circuit board so that the electronic device 100 may receive data input by the user on the keyboard 22, etc.

[0113] The touch module 23, as another input module on the body 2, can also be electrically connected to the circuit board. The user can input operation instructions on the touch panel by pressing or touching. For example, when the user presses the touch module 23, the mouse click function of the electronic device 100 can be realized. For example, when the user's finger drags on the touch module 23, the cursor on the display screen 12 can be moved.

[0114] Continue to see Figure 1, the electronic device 100 may include a shell. The shell may include a screen shell 11 and a body shell. The side of the screen shell 11 facing away from the display screen 12 forms the A side of the shell. The side of the screen component 1 on which the display screen 12 is mounted forms the B side of the shell. The side of the body 2 provided with the keyboard 22 and the touch module 23 constitutes the C side of the shell, and the side of the body 2 opposite to the keyboard 22 and the touch module 23 constitutes the D side of the shell.

[0115] Continue to see Figure 1 The body shell may include a mounting shell 21 and a bottom shell (not shown). The bottom shell is connected to one side of the mounting shell 21. The mounting shell 21 may be referred to as a C shell in the shell. The bottom shell may be referred to as a D shell in the shell.

[0116] Continue to see Figure 1 , the keyboard 22 and the touch module 23 are installed on the side of the mounting shell 21 away from the bottom shell. The keyboard 22 can be set on the side of the body shell adjacent to the hinge mechanism 3. The touch module 23 can be located on the side of the body shell away from the hinge mechanism 3, so as to facilitate the user's operation on the touch module 23. In this case, the touch module 23 and the keyboard 22 are located on both side edges of the body shell in the X direction. The X direction is the width direction of the body 2.

[0117] Figure 2 The schematic diagram shows the assembly of the touch module 23 on the housing. Figure 2 The keyboard 22 is not shown. Figure 2 As shown, the mounting shell 21 is provided with openings 213 at positions corresponding to the keyboard 22 and the touch module 23. The openings 213 are connected to the cavity 214 in the body shell. The keyboard 22 and the touch module 23 are mounted in the corresponding openings 213 on the mounting shell 21, so that the keyboard 22 and the touch module 23 are electrically connected to the circuit board.

[0118] When the user inputs an operation instruction by pressing, the touch module 23 can sense the user's pressing and provide the user with pressing feedback to enhance the user's hand feeling. The pressing feedback is mainly the feedback of the pressing force value.

[0119] When the pressing force value fed back by the touch module 23 is too large, it will affect the user's hand feeling, and the user will feel poor when pressing the touch module 23. When the pressing force value fed back by the touch module 23 is too small, the user will not feel any pressing force value feedback when experiencing the pressing of the touch module 23, and the user's feeling of the touch module 23 may be that the pressing elasticity of the touch panel is weak. Therefore, the size of the pressing force value fed back by the touch module 23 is crucial to the user's experience.

[0120] According to whether the touch module 23 has the function of inputting operation instructions by pressing (hereinafter referred to as the pressing input function) when it leaves the factory, the touch module 23 can be divided into a full-module touch module and a semi-module touch module. The full-module touch module has the pressing input function when it leaves the factory. The semi-module touch module does not have the pressing input function when it leaves the factory. The semi-module touch module needs to be assembled on the body shell of the electronic device 100, and the touch switch 2321 on the semi-module touch module cooperates with the protrusion 2121 on the body shell to realize the pressing input function.

[0121] Since the semi-modular touch module has advantages such as simple structure, low cost, and good assembly performance, the semi-modular touch module is widely used in the electronic device 100 .

[0122] Figure 3 as well as Figure 4 Schematically shows the structure of a touch module 23a. The touch module 23a is a semi-module touch module. Figure 3 and Figure 4 As shown, the touch module 23a may include a stacked cover plate 231a, a touch circuit board 232a and a support member 233a. The cover plate 231a and the support member 233a are respectively bonded to the two surfaces of the touch circuit board 232a by adhesive. The side of the cover plate 231a away from the touch circuit board 232a forms the touch surface 2031 of the touch module 23a. The side where the touch surface 2031 is located can be understood as the front side of the touch module 23a. The side of the support member 233a away from the touch circuit board 232a forms the back side of the touch module 23a. The back side can also be called the installation surface of the touch module 23a. The structure of the touch module 23a on one side of the installation surface can be seen in Figure 3 The structure of the touch module 23a on the touch surface 2031 side can be seen in Figure 4 shown.

[0123] The support member 233a may be a metal member. For example, the metal member may be an iron member, etc. The support member 233a can enhance the structural rigidity of the touch module 23 and facilitate the connection of the touch module 23a with the mounting shell 21 at the support member 233a to achieve installation of the touch module 23a in the mounting shell 21.

[0124] See also Figure 4 As shown, when the touch module 23 a is assembled in the mounting shell 21 of the body 2 , the touch surface 2031 of the touch module 23 a is exposed on the surface of the body 2 , and the mounting surface of the touch module 23 a is hidden inside the body 2 .

[0125] See again Figure 3The touch module 23a further includes a locking ear 4 and a spring 5. The spring 5 can also be called a spring foot. Along the X direction, the locking ear 4 and the spring 5 are distributed on both sides of the touch module 23a, and are both mounted on the support member 233a by means of fasteners or the like. Exemplarily, the fasteners may include screws, bolts, and the like. Figure 3 3 locking ears 4 are shown in FIG. 4 . For example, the number of the locking ears 4 can be three. The three locking ears 4 can be installed on the support member 233a at intervals along the Y direction.

[0126] Figure 5 and Figure 6 Schematic diagrams of the installation of the touch module 23a at different locking ears 4 in the installation shell 21 are shown respectively. Figure 5 and Figure 6 As shown, the end of the locking ear 4 can be mounted on the mounting shell 21 by a fastener to connect the support member 233 a to the mounting shell 21 , thereby achieving installation and fixation of the touch module 23 a in the mounting shell 21 .

[0127] See also Figure 5 As shown, the mounting shell 21 has a support platform 2122 on the inner wall at the opening 213. The spring sheet 5 can be located between the support member 233a and the support platform 2122. The free end of the spring sheet 5 abuts against the support platform 2122, so that the touch module 23a is elastically supported on the mounting shell 21.

[0128] See also Figure 6 Combined with Figure 3 As shown, a touch switch 2321 is provided on the touch circuit board 232a. The touch switch 2321 is located on the side of the touch circuit board 232a facing the support member 233a. Exemplarily, the touch switch 2321 can be a pot piece. The mounting shell 21 has a protrusion 2121 at a position corresponding to the touch switch 2321. The protrusion 2121 can also be called a hammer. When the touch module 23a is installed in the mounting shell 21, the touch switch 2321 contacts the protrusion 2121.

[0129] Continue to see Figure 6 When the user presses the touch module 23a, the touch module 23a moves downward in the opening 213. When the touch switch 2321 moves downward, under the action of the protrusion 2121, the touch switch 2321 elastically deforms toward one side of the touch circuit board 232a, and contacts the exposed copper area on the touch circuit board 232a, thereby triggering the touch circuit board 232a and realizing the press input function of the touch module 23a. It should be noted that the directions or positional relationships indicated by "up", "down", etc. are based on the directions or positional relationships shown in the accompanying drawings.

[0130] When the touch module 23a moves downward in the opening 213, in addition to the touch switch 2321, the lock ear 4 and the spring 5 will also undergo elastic deformation. After the user's pressing is cancelled, the touch switch 2321, the lock ear 4 and the spring 5 will all generate deformation forces due to elastic deformation, and these deformation forces will be applied to the touch module 23a. Therefore, after the user's pressing force disappears, the touch module 23a will move upward in the opening 213 under the action of these deformation forces to achieve the reset of the touch module 23a. In addition, the touch switch 2321, the lock ear 4 and the spring 5 will provide the user with feedback on the pressing force value of the touch module 23a.

[0131] In addition to the deformation force of the touch switch 2321 , the deformation force of the lock ear 4 , and the deformation force of the spring 5 , the source of the pressing force value of the touch module 23 a also includes the deformation force of the support member 233 a .

[0132] During the manufacturing and production line assembly process of the touch module 23a, the spring piece 5, the locking ear 4 and the support member 233a are easily deformed. When the spring piece 5, the locking ear 4 and the support member 233a are all deformed, the touch module 23a is easily deformed beyond the standard. This will cause the pressing force value fed back by the touch module 23a to be too large, making the user feel poor when pressing the touch module 23a, affecting the user experience.

[0133] In view of this, the electronic device 100 provided in the present application includes a touch module 23, which is a semi-module touch module. The touch module 23 cancels the structure of the lock ear 4 of the touch module 23a in the related art, and replaces the lock ear 4 by setting a rotating member 234 to achieve the connection between the support member 233a and the body shell in the shell, thereby achieving the assembly of the touch module 23a on the shell, and can solve the problem of poor hand feeling of the user when pressing the touch module 23a caused by the excessive pressing force value fed back by the touch module 23a, so as to improve the user experience. Compared with the lock ear 4, since the rotating member 234 has the characteristics of simple structure, it can also reduce the cost of the touch module 23 and the electronic device 100.

[0134] The touch module 23 includes a touch unit. The touch unit is configured to be mounted on the housing so as to achieve the installation of the touch module 23 on the housing. The installation position of the touch module 23 on the housing can be seen in Figure 2 shown.

[0135] The structure of the touch module 23 is further described below in conjunction with the accompanying drawings.

[0136] Figure 7 The structural diagram of the touch module 23 is schematically shown. Figure 8 The exploded view of the touch module 23 is schematically shown. Figure 7 and Figure 8As shown, the touch unit has a touch surface 2031. When the touch module 23 is installed on the housing, the touch surface 2031 is exposed on the surface of the housing to facilitate the user's operation on the touch surface 2031. The touch unit includes a touch circuit board 232. The touch circuit board 232 has a first surface and a second surface in the thickness direction. The thickness direction of the touch circuit board 232 is parallel to the thickness direction of the body 2, which can be seen as the Z direction. Among them, the first surface faces the touch surface 2031. Correspondingly, the first surface is away from the touch surface 2031.

[0137] The touch control unit further includes a cover plate 231. The cover plate 231 is covered on the first surface of the touch control circuit board 232 to form a touch control surface 2031, so that the user can input operation instructions by pressing or touching the cover plate 231. In addition, since the cover plate 231 is covered on the first surface of the touch control circuit board 232, the touch control circuit board 232 can be prevented from being exposed on the surface of the electronic device 100, so as to realize the protection function of the touch control circuit board 232.

[0138] The cover plate 231 is connected to the first surface of the touch circuit board 232 so as to fix the cover plate 231 on the touch circuit board 232. As a possible implementation, the cover plate 231 can be connected to the first surface of the touch circuit board 232 by bonding. Specifically, a first bonding layer (not shown) can be provided between the cover plate 231 and the touch circuit board 232, and the cover plate 231 can be connected to the first surface of the touch circuit board 232 by the first bonding layer. For example, the first bonding layer can be adhesive-backed.

[0139] Continue to see Figure 8 The touch module 23 includes a support member 233. The support member 233 is supported on the second surface of the touch circuit board 232 and elastically abuts against the housing, so that the touch unit is installed on the housing through the support member 233. Since the support member 233 elastically abuts against the housing, the touch module 23 can move relative to the housing toward the inside of the housing under pressure, thereby realizing the press input function of the touch module 23.

[0140] Furthermore, by elastically abutting the support member 233 against the shell, when the pressing force applied to the touch module 23 disappears, the touch module can be easily moved toward the outside of the shell to reset the touch module and provide feedback of the pressing force value of the touch module 23 to the user.

[0141] The support member 233 is connected to the second surface of the touch circuit board 232, so that the touch unit is installed on the housing through the support member 233. As a possible implementation, the support member 233 can be connected to the second surface of the touch circuit board 232 by bonding. Specifically, a second adhesive layer 238 can be provided between the support member 233 and the touch circuit board 232, and the support member 233 can be connected to the second surface of the touch circuit board 232 through the first adhesive layer. For example, the second adhesive layer 238 can be adhesive-backed.

[0142] The support member 233 may be a support plate, so that the support member 233 has a larger support area for the touch circuit board 232, so that when the touch unit is supported by the support member 233 and installed in the housing, the stability of the installation of the touch unit and the touch module 23 in the housing can be enhanced.

[0143] The support plate may be a metal plate. For example, the support plate may be an iron plate, etc. The metal plate can enhance the structural rigidity of the touch module 23.

[0144] Continue to see Figure 8 The support member 233 has a first mounting portion 2333. The rotating member 234 is connected to the first mounting portion 2333 and fixed to the housing. The support member 233 is configured to be rotatably connected to the housing through the rotating member 234. By providing the rotating member 234, the support member 233 can be rotatably connected to the housing through the rotating member 234, and since the support member 233 elastically abuts against the housing, the support member 233 can be fixed to the housing.

[0145] Since the support member 233 is supported on the second surface of the touch circuit board 232, the touch circuit board 232 can be installed and fixed on the housing through the support member 233. In this way, when the touch unit is pressed, the support member 233 can move relative to the housing around the rotating member 234 toward the inside of the housing, and drive the touch unit to move relative to the housing around the rotating member 234 toward the inside of the housing, thereby ensuring the normal use of the press input function of the touch module 23. When the touch unit is pressed, the rotating member 234 does not undergo elastic deformation.

[0146] Therefore, on the basis of ensuring the normal use of the pressing input function of the touch module 23, the present application can replace the locking ear 4 through the rotating member 234 to realize the installation of the supporting member 233 on the shell, while also eliminating the source of the pressing force value of the touch module 23 caused by the deformation of the locking ear 4.

[0147] When the sources of the pressing force values ​​of the touch module 23 are reduced, the degree of deformation exceeding the standard during the manufacturing and production line assembly process of the touch module 23 can be reduced, thereby avoiding the problem of excessive pressing force values ​​being fed back during the manufacturing and production line assembly process of the touch module 23, thereby improving the user experience when the user presses the touch module 23.

[0148] Moreover, since the deformation of the lock ear 4 cancels the source of the pressing force value of the touch module 23, the number of sources of the pressing force value of the touch module 23 can be reduced, so that the pressing force value of the touch module 23 can be better controlled, so as to better control the user experience when the user presses the touch module 23.

[0149] Compared with the lock ear 4, the rotating member 234 has the characteristics of simple structure, low cost and light weight. Therefore, when the locking ear 4 is replaced by the rotating member 234, the cost and weight of the touch module 23 can be reduced, so as to make the electronic device 100 lighter and thinner.

[0150] The rotating member 234 can be fixed on the first mounting portion 2333 to enhance the connection strength between the rotating member 234 and the first mounting portion 2333, thereby enhancing the stability of the support member 233 and the touch unit installed on the housing. For example, the rotating member 234 can be fixed on the first mounting portion 2333 by riveting, welding, etc., so as to achieve the connection between the rotating member 234 and the first mounting portion 2333.

[0151] Fig. 9 The schematic diagram shows the structure of the touch module 23 on the housing. Figure 1 See also Fig. 9 As shown, the housing has a cavity 214 in it and an opening 213 communicating with the cavity 214 is formed on the housing.

[0152] The touch unit is located in the opening 213, so that the touch surface 2031 is exposed on the outer surface of the shell, so as to facilitate the user's operation on the touch surface 2031. Since the opening 213 is connected to the cavity 214, when the touch unit is located in the opening 213, it is also convenient to electrically connect the touch module 23 with the circuit board in the cavity 214. Among them, the cavity 214 can be formed in the mounting shell 21 in the shell. The opening 213 can be opened on a side of the mounting shell 21 away from the bottom shell, so that the touch module 23 can be installed in the opening 213 of the mounting shell 21 through the rotating member 234.

[0153] Continue to see Fig. 9 The rotating member 234 is fixed to the inner surface of the shell so that the support member 233 can be rotatably connected to the inner surface of the shell through the rotating member 234. While the touch unit is installed in the opening 213 of the shell, the rotating member 234 can be hidden in the shell (such as a body shell) to ensure that the aesthetics of the electronic device 100 is not affected.

[0154] Fig.10 The schematic diagram of assembling the touch module 23 on the housing from another viewing angle is shown schematically. Fig.102 shows the structure of the touch module 23 on the mounting surface. Similar to the touch module 23 in the related art, the mounting surface is the surface of the touch module 23 opposite to the touch surface 2031 .

[0155] See also Fig.10 As shown, the rotating member 234 can be fixed on the inner surface of the mounting shell 21. Since the touch unit can be mounted on the mounting shell 21, and the present application is mainly an improvement on the touch module 23, the inner surface of the shell in the present application can be regarded as the inner surface of the mounting shell 21, and the outer surface of the shell can be regarded as the outer surface of the mounting shell 21. Among them, the inner surface of the mounting shell 21 refers to the side of the mounting shell 21 facing the cavity 214. The outer surface of the mounting shell 21 refers to the side of the mounting shell 21 away from the cavity 214.

[0156] The mounting shell 21 in the housing may include a metal shell 211 and a plastic shell 212. Alternatively, the mounting shell 21 may also include only the metal shell 211. When the mounting shell 21 includes the metal shell 211 and the plastic shell 212, the plastic shell 212 may be located inside the metal shell 211 to form the inner surface of the mounting shell 21, and the metal shell 211 may form the outer surface of the mounting shell 21. The metal shell 211 and the plastic shell 212 are both provided with openings 213 at positions corresponding to the touch control units. Compared with the arrangement in which the mounting shell 21 includes only the metal shell 211, when the mounting shell 21 includes the plastic shell 212 and the metal shell 211, a plurality of grooves may be formed on the plastic shell 212, or the plastic shell 212 may form a plurality of grooves on the mounting shell 21 with the metal shell 211, so as to realize the installation of the touch control module 23 in the groove while simplifying the manufacturing process of the mounting shell 21. Moreover, by providing the plastic shell 212, the weight of the electronic device 100 may also be reduced.

[0157] The structure of the electronic device 100 is further described below by taking the installation shell 21 including the metal shell 211 and the plastic shell 212 as an example.

[0158] Fig.11 Shows Fig.10 Enlarged view of part A. See Fig.11 As shown, the rotating member 234 is connected to the side wall of the first mounting portion 2333 in the thickness direction of the touch circuit board 232, and is disposed on the inner surface of the housing so that the rotating member 234 can be fixed to the inner surface of the mounting shell 21. The thickness direction of the first mounting portion 2333 is parallel to the thickness direction of the touch circuit board 232, which can be seen in the Z direction.

[0159] Compared with the connection between the rotating member 234 and the side wall of the first mounting portion 2333 in the Y direction, by connecting the rotating member 234 to the side wall of the first mounting portion 2333 in the Z direction, while ensuring that the rotating member 234 can be fixed on the inner surface of the mounting shell 21, it can avoid that the rotating member 234 occupies the space of the shell in the cavity 214, so as to ensure the normal assembly of the components of the electronic device 100 in the cavity 214, which is conducive to the lightweight of the electronic device 100.

[0160] The structures of the touch module 23 and the electronic device 100 are further described below by taking the example that the rotating member 234 is connected to the side wall of the first mounting portion 2333 in the Z direction.

[0161] Continue to see Fig.11 The touch module 23 further includes an adapter 235. The rotating member 234 is fixed to the housing through the adapter 235. Specifically, the rotating member 234 is fixed to the inner surface of the mounting shell 21 through the adapter 235. The rotating member 234 is rotatably arranged between the housing and the adapter 235, so that the rotating member 234 can be fixed to the inner surface of the mounting shell 21 through the adapter 235 and can also rotate between the housing and the adapter 235. In this way, when the touch module 23 is pressed, the touch module 23 can rotate around the rotating member 234 toward the cavity 214 of the housing to ensure the press input function of the touch module 23.

[0162] Continue to see Fig.11 , the adapter 235 can be pressed onto the rotating member 234. The adapter 235 can be connected to the housing and form an assembly hole (not shown) with the housing. The rotating member 234 is rotatably arranged in the assembly hole, so that the rotating member 234 can be fixed to the inner surface of the housing through the adapter 235, and the rotating member 234 can be rotatably arranged between the housing and the adapter 235.

[0163] Furthermore, by setting the assembly hole, the rotation of the rotating member 234 between the shell and the adapter 235 can be restricted to ensure that the rotating member 234 can only rotate within the assembly hole to avoid the rotation of the rotating member 234 affecting the installation of the support member 233 and the touch unit in the shell.

[0164] The shape of the assembly hole is adapted to the shape of the circumferential outer wall of the rotating member 234. In other words, the shape of the assembly hole is the same as or similar to the shape of the circumferential outer wall of the rotating member 234. When the rotating member 234 is a rotating shaft, the assembly hole can be a circular hole.

[0165] Fig.12 Shows Fig. 9 Enlarged view of part B. Fig.13 Shows Fig. 9 Enlarged view of section C. See Fig.12As shown, the adapter 235 has a first half hole 2351 on the side facing the rotating member 234. Fig.13 As shown, the inner surface of the shell has a second half hole 2151. Specifically, the second half hole 2151 can be located on the inner surface of the mounting shell 21. When the adapter 235 is connected to the shell, the first half hole 2351 and the second half hole 2151 form an assembly hole. In this way, the rotating member 234 is fixed to the inner surface of the shell through the adapter 235, and the rotating member 234 is rotated in the assembly hole. At the same time, the thickness of the shell can be reasonably utilized to form an assembly hole with the adapter 235 to avoid the thickness of the adapter 235 being too large.

[0166] When the rotating member 234 is located in the assembly hole, the rotating member 234 can be matched with the hole wall of the assembly hole to facilitate the rotation of the rotating member 234 in the assembly hole. To facilitate the matching of the hole wall of the rotating member 234 with the hole wall of the assembly hole, the radius of the first half hole 2351 and the second half hole 2151 can be greater than the radius of the rotating member 234.

[0167] See also Fig.12 and Fig.13 As shown, the first half hole 2351 and the second half hole 2151 can both be half of the assembly hole. In this case, the first half hole 2351 and the second half hole 2151 can be symmetrical structures. Fig.12 and Fig.13 It does not constitute a limitation on the structure of the first half hole 2351 and the second half hole 2151. For example, in some embodiments, the first half hole 2351 and the second half hole 2151 can also be an asymmetric structure. In the present application, the structure of the first half hole 2351 and the second half hole 2151 is not particularly limited.

[0168] The adapter 235 can be detachably connected to the housing so that the adapter 235 can be fixed to the housing while the touch module 23 is being disassembled. For example, the adapter 235 can be detachably connected to the housing by means of a snap connection, a fastener, etc. Specifically, the adapter 235 can be detachably connected to the mounting shell 21 in the housing by means of a snap connection, a fastener, etc. Exemplarily, the fastener can be a screw, a bolt, etc.

[0169] It should be noted that when the adapter 235 can be detachably connected to the mounting shell 21 by a fastener, the adapter 235 has a first connection hole, and the inner surface of the mounting shell 21 has a second connection hole 2153. The fastener can pass through the first connection hole and be fixed in the second connection hole 2153 by screwing or the like, so that the adapter 235 can be connected to the mounting shell 21 and the adapter 235 can be fixed on the mounting shell 21 at the same time.

[0170] One rotating member 234 may correspond to more than two fasteners ( Fig.12Two fasteners are shown). Two or more fasteners may be located on both sides of the rotating member 234, so that the adapter 235 is fixed to both sides of the rotating member 234 by the two or more fasteners to restrict the rotating member 234 in the assembly hole.

[0171] See also Fig.13 As shown, in some embodiments, a first groove 215 may be provided on the inner surface of the housing. The first groove 215 may be formed on the plastic housing 212 of the mounting housing 21. Fig.13 Combined with Fig.12 As shown, the first slot body 215 is correspondingly arranged with the adapter 235. The adapter 235 is located in the first slot body 215, and the second half hole 2151 can be located at the bottom of the first slot body 215. In this way, the rotating member 234 can be embedded in the bottom of the first slot body 215. After the adapter 235 is pressed on the rotating member 234, the adapter 235 can also be embedded in the mounting shell 21 in the shell, so that the adapter 235 can be connected to the shell while avoiding the further avoidance of the rotating member 234 and the adapter 235. The space of the shell in the cavity 214 is occupied, so as to ensure the normal assembly of the components of the electronic device 100 in the cavity 214, which is conducive to the thinness of the electronic device 100.

[0172] Continue to see Fig.13 The first groove body 215 is connected to the opening 213 so that when the touch unit is installed in the opening 213 , the rotating member 234 can be located in the second half hole 2151 .

[0173] The second connection hole 2153 may be located at the bottom of the first slot body 215 and at the side of the second half hole 2151 .

[0174] It should be noted that, when there are no excessive requirements on the thickness of the electronic device 100 , the adapter 235 does not need to be embedded in the mounting shell 21 .

[0175] The following takes the example of the adapter 235 being embedded in the mounting shell 21 to further illustrate the structures of the touch module 23 and the electronic device 100 .

[0176] See again Fig.12 , there are two rotating members 234 on the first mounting portion 2333. Along the length direction of the touch circuit board 232, the two rotating members 234 are distributed on both sides of the first mounting portion 2333. The length direction of the touch circuit board 232 can refer to the Y direction. Alternatively, the two rotating members 234 can be connected to each other to form a rotating shaft. In this application, the structure of the touch module 23 is further described by taking the two rotating members 234 distributed on both sides of the first mounting portion 2333 as an example.

[0177] The two rotating members 234 correspond to a transfer member 235 respectively, and the two rotating members 234 can be fixed to the inner surface of the housing through their corresponding transfer members 235. The first mounting portion 2333 can be fixed to the inner surface of the housing through the two rotating members 234 and the transfer members 235 corresponding to the two rotating members 234, so as to enhance the stability of the connection between the support member 233 and the housing, thereby ensuring the stability of the assembly of the touch module 23 on the housing.

[0178] See again Fig.12 In some embodiments, the two adapters 235 located at the first installation portion 2333 may be connected to each other. In other embodiments, the two adapters 235 located at the first installation portion 2333 may not be connected. When the two adapters 235 located at the first installation portion 2333 are connected to each other, the consistency of the rotation of the touch module 23 around the two rotating members 234 can be ensured.

[0179] For example, the two adapters 235 can be connected by a connecting arm 236. The connecting arm 236 can be connected to the two adapters 235 in an integrated manner to form an integral part with the two adapters 235. Since the formed integral part is pressed on the rotating member 234, the formed integral part can also be called a rotating cover. At this time, a rotating cover can be pressed on two rotating members 234 of a first mounting portion 2333 to simplify the number of parts in the touch module 23, so as to facilitate the connection between the support member 233 and the shell. The rotating cover cooperates with the two rotating members 234 and the mounting shell 21 to form a rotating pair.

[0180] The structures of the touch module 23 and the electronic device 100 are further described below by taking the integrated connection between the connecting arm 236 and the two adapters 235 as an example.

[0181] Fig.14 FIG. 2 shows a schematic diagram of the structure of the touch module 23 at a second viewing angle. Fig.14 Combined with Fig.13 As shown, the first mounting portion 2333 is a protruding structure on the side edge of the support member 233. A second groove 2152 is provided on the inner surface of the housing, the second groove 2152 is communicated with the opening 213, and at least part of the first mounting portion 2333 is located in the second groove 2152. In this way, when the touch unit is installed in the opening 213, part of the first mounting portion 2333 can be located in the second groove 2152, so that the first mounting portion 2333 is fixed in the second groove 2152 through the rotating member 234 and the adapter 235, and the first mounting portion 2333 can be embedded in the mounting shell 21, so as to avoid the setting of the rotating member 234 and the adapter 235, which occupies the space of the housing in the cavity 214, so as to ensure the normal assembly of the components of the electronic device 100 in the cavity 214.

[0182] See again Fig.13 , the second slot body 2152 can be located at the bottom of the first slot body 215. The second slot body 2152 can be understood as a recessed portion of the first slot body 215 on the bottom of the slot. The second slot body 2152 can be surrounded by a metal shell 211 and a plastic shell 212 on the mounting shell 21. Among them, the metal shell 211 can form the bottom of the second slot body 2152. When the rotating member 234 is fixed to the inner surface of the mounting shell 21 through the adapter 235, the first mounting portion 2333 can overlap the bottom of the second slot body 2152, so that the first mounting portion 2333 as a whole can be better embedded in the first slot body 215. In this way, the setting of the rotating member 234 and the adapter 235 can be avoided, and the space of the shell in the cavity 214 is occupied, so as to ensure the normal assembly of the components of the electronic device 100 in the cavity 214.

[0183] By setting the first mounting portion 2333 as a raised structure on the support member 233, the support member 233 is connected to the mounting shell 21 in the shell, and the touch unit is installed in the opening 213 of the mounting shell 21. At the same time, the opening area on the shell can be reduced, and the rotating member 234 can be fixed on the inner surface of the mounting shell 21.

[0184] Continue to see Fig.14 , the number of the first mounting parts 2333 can be more than two. Along the length direction (Y direction) of the touch unit, more than two first mounting parts 2333 are arranged on the support member 233 at intervals. A rotating member 234 is correspondingly installed on each first mounting part 2333. Alternatively, the number of the first mounting part 2333 can also be one. For example, a first mounting part 2333 can be located in the middle (middle area) of the support member 233. Compared with the structure of one first mounting part 2333, by setting more than two first mounting parts 2333, the size of the first slot body 215 can be reduced to enhance the strength of the shell. At the same time, the shell, the rotating member 234 and the two adapters 235 (rotating cover plates) connected to each other on the first mounting part 2333 can form more than two rotating pairs, so that when the touch unit is pressed, the support member 233 in the touch module 23 and the touch unit rotate around the rotating member 234.

[0185] Fig.14 Two first mounting parts 2333 are shown in FIG. The two first mounting parts 2333 can be arranged at both side edges of the support member 233 in the Y direction. In some embodiments, there can be three first mounting parts 2333, etc. In the present application, the number of the first mounting parts 2333 is not particularly limited.

[0186] Continue to see Fig.14, which is the same as the touch module 23 in the related art. The touch circuit board 232 has a touch switch 2321 on the second surface. The structure of the touch switch 2321 is the same as the structure of the touch switch 2321 in the touch module 23 in the related art, and will not be repeated here. The touch switch 2321 is exposed on the side of the support member 233 away from the touch circuit board 232, so as to realize the press input function of the touch module 23.

[0187] The support member 233 has a through hole 2334. The touch switch 2321 is exposed on the side of the support member 233 away from the touch circuit board 232 through the through hole 2334. The through hole 2334 is arranged opposite to the touch switch 2321, so that when the support member 233 is supported on the touch circuit board 232, the touch switch 2321 can be exposed on the side of the support member 233 away from the touch circuit board 232 through the through hole 2334.

[0188] The size of the through hole 2334 is larger than the size of the touch switch 2321. The shape of the through hole 2334 can be the same as or similar to the shape of the touch switch 2321. For example, the through hole 2334 can be a round hole. Alternatively, the shape of the through hole 2334 can also be different from the shape of the touch switch 2321. In the present application, the shape of the through hole 2334 is not particularly limited.

[0189] Fig.15 Schematically shows Fig.10 Partial cross-section in the DD direction. Fig.15 As shown, the interior of the housing has a protrusion 2121 protruding toward one side of the support member 233. The housing has a support platform 2122, and the protrusion 2121 can be arranged on the side of the support platform 2122 facing the support member 233. Specifically, the support platform 2122 can be a protrusion formed on the wall of the cavity 214 of the mounting shell 21.

[0190] Continue to see Fig.15 The touch switch 2321 is configured to be elastically deformed toward the second surface under the action of the protrusion 2121 when the touch unit is pressed, so as to trigger the touch circuit board 232. In this way, when the user presses the touch module 23, the touch unit and the support member 233 can rotate around the rotating member 234 toward one side of the protrusion 2121. Under the action of the protrusion 2121, the touch switch 2321 elastically deforms toward one side of the touch circuit board 232, thereby triggering the touch circuit board 232 and realizing the press input function of the touch module 23. After the user's pressing force disappears, the deformation force generated by the touch switch 2321 causes the touch unit and the support member 233 to rotate around the rotating member 234 toward the side away from the protrusion 2121, so as to realize the reset of the touch module 23.

[0191] In addition to the deformation force of the touch switch 2321 , the deformation force of the lock ear 4 , and the deformation force of the spring 5 , the source of the pressing force value of the touch module 23 also includes the deformation force of the support member 233 .

[0192] See again Fig.10 , the shell has a user side 218 and a non-user side 219 in the width direction of the touch circuit board 232. The width direction of the touch circuit board 232 is parallel to the width direction of the body 2, which can be referred to as the X direction. That is to say, the mounting shell 21 has a user side 218 and a non-user side 219 in the X direction. The touch circuit board 232 is arranged on the mounting shell 21 adjacent to the user side 218. A first mounting portion 2333 is provided on a side of the support member 233 adjacent to the non-user side 219, and a side of the support member 233 adjacent to the user side 218 is elastically abutted against the shell. Specifically, a side of the support member 233 adjacent to the user side 218 can be elastically abutted against the mounting shell 21 in the shell. The side of the support member 233 adjacent to the user side 218 of the shell can be called the ground side, and the side adjacent to the non-user side 219 can be called the sky side. In this way, the user can press the touch unit on one side of the user side 218 to realize the pressing input function of the touch module 23. At the same time, the touch module 23 can be easily reset because the support member 233 is elastically abutted against the shell.

[0193] It should be noted that the pressing range of the touch module 23 of the present application is the middle part of the cover plate 231 of the touch unit and the side of the cover plate 231 facing the user side 218 .

[0194] Fig.16 Schematically shows Fig.10 Partial cross-section in the EE direction. Fig.16 Combined with Fig.14 As shown, the touch module 23 further includes a first elastic member 237. The first elastic member 237 is connected to a side of the support member 233 away from the touch circuit board 232. When the touch unit is mounted on the housing, the first elastic member 237 abuts against the support platform 2122 of the housing to achieve elastic abutment between the support member 233 and the housing.

[0195] The first elastic member 237 and the first mounting portion 2333 are located on opposite sides of the support member 233, so that the side of the support member 233 adjacent to the user side 218 of the housing elastically abuts against the housing to facilitate the user's operation on the touch module 23. At this time, the first elastic member 237 can be arranged on the ground side of the support member 233. The number of the first elastic members 237 can be more than two. More than two first elastic members 237 can be arranged on the support member 233 at intervals along the Y direction. Fig.14 Two first elastic members 237 are shown, but this does not limit the number of the first elastic members 237 .

[0196] The first elastic member 237 may include an elastic member such as a spring sheet, foam, etc. The elastic contact between the first elastic member 237 and the housing is further described below by taking the spring sheet as an example.

[0197] Continue to see Fig.16 , the first end 2371 of the first elastic member 237 can be connected to the support member 233, and the second end 2372 of the spring 5 is bent toward one side of the support platform 2122 and supported on the support platform 2122, so as to realize the elastic contact between the support member 233 and the mounting shell 21 in the housing. The first elastic member 237 can be connected to the support member 233 by means of a clamping, a fastener, etc., so as to realize the installation of the first elastic member 237 on the support member 233. When the first elastic member 237 is a spring 5, the second end 2372 of the first elastic member 237 can also be called a free end.

[0198] It should be noted that, in addition to the touch switch 2321, when the touch unit is pressed, the first elastic member 237 will also produce elastic deformation. Therefore, after the pressing force on the touch unit disappears, the deformation force generated by the first elastic member 237 will also cause the touch unit and the support member 233 to rotate around the rotating member 234 toward the side away from the protrusion 2121, thereby achieving the reset of the touch module 23 and improving the feedback of the pressing force value for the user. Therefore, the feedback of the pressing force value of the touch module 23 of the present application is provided by the touch switch and the first elastic member 237, reducing the provision of the lock ear 4, so as to avoid excessive pressing force value due to deformation of the lock ear 4, and facilitate the control of the pressing force value of the touch module 23.

[0199] Fig.17 The figure shows a schematic diagram of assembling a touch module 23 on a deformed mounting shell 21 in the related art. Fig.17 Only a portion of the mounting housing 21 is shown. Fig.17 Combined with Figure 2 As shown, the mounting shell 21 is provided with openings 213 at the positions corresponding to the keyboard 22 and the touch module 23. This will cause the mounting shell 21 to form two beams on both sides of the width direction (X direction) of the touch module 23. For the convenience of description, the two beams are defined as an upper beam 216 and a lower beam 217. The upper beam 216 is located between the keyboard 22 and the touch module 23, and the lower beam 217 is away from the keyboard 22.

[0200] When the touch module 23 is installed on the mounting shell 21, the touch surface 2031 of the touch module 23 is lower than the outer surface of the mounting shell 21, and there is a designed step difference between the touch module 23 and the mounting shell 21 to prevent the touch module 23 from protruding from the outer surface of the mounting shell 21, which affects the user's operation on the touch module 23. At the same time, the step difference between the touch module 23 and the mounting shell 21 is controlled within a certain range by the designed step difference. For example, the designed step difference can be 0.2mm. Part of the outer surface of the mounting shell 21 forms the C surface of the shell. The step difference between the touch module 23 and the mounting shell 21 can be understood as the step difference between the touch surface 2031 of the touch module 23 and the outer surface of the mounting shell 21.

[0201] Continue to see Fig.17 The two sides of the mounting shell 21, the upper crossbeam 216, the lower crossbeam 217 and the touch module 23a in the Y direction can be called the left side and the right side. The mounting shell 21 may have a problem of inconsistent deformation on the left and right sides of the upper crossbeam 216. Correspondingly, the mounting shell 21 may also have a problem of inconsistent deformation on the left and right sides of the lower crossbeam 217. The support member 233a may also have a problem of inconsistent deformation on the left and right sides of the touch module 23a.

[0202] The touch module 23a in the related art is installed in the mounting shell 21, and when the mounting shell 21 has the above-mentioned inconsistency in deformation between the left and right sides at the upper crossbeam 216, the following problems may occur:

[0203] 1. The initial step difference between the touch module 23a and the mounting shell 21 is larger than the design step difference mentioned above, and the initial step difference exceeds the standard, so that the step difference between the touch module 23a and the mounting shell 21 is too large, resulting in poor appearance refinement of the electronic device 100; wherein the initial step difference refers to the step difference between the touch module and the mounting shell 21 when the touch module is not pressed;

[0204] 2. The problem of poor uniformity of the step difference between the left and right sides of the touch module 23a and the mounting shell 21 also leads to poor refinement of the appearance of the electronic device 100;

[0205] 3. This causes the problem of inconsistent pressing force values ​​on the left and right sides of the touch module 23a.

[0206] For example, see Fig.17, when the right side of the upper cross beam 216 undergoes convex female deformation or convex male deformation, and the left side of the upper cross beam 216 does not undergo deformation, the mounting shell 21 will have a problem of inconsistent deformation degree on the left and right sides of the upper cross beam 216. For the mounting shell 21, the convex female deformation of the upper cross beam 216 refers to the deformation of the upper cross beam 216 protruding toward the outer surface of the mounting shell 21. Correspondingly, the convex male deformation of the upper cross beam 216 refers to the deformation of the upper cross beam 216 protruding toward the outer surface away from the mounting shell 21. In other words, the convex male deformation of the upper cross beam 216 can be understood as the deformation of the upper cross beam 216 concave toward the inside of the mounting shell 21.

[0207] Since the lock ear 4 is locked on the upper crossbeam 216 (such as Figure 5 Therefore, when the mounting shell 21 is deformed at the position (position M) on the right side of the upper crossbeam 216, the touch module 23a is driven to move toward the outer surface of the mounting shell 21 in the Z direction. At this time, the right side of the touch module 23a will move toward the outer surface of the mounting shell 21 as a whole, so that the step difference between the right side of the touch module 23a and the mounting shell 21 is reduced and is less than the designed step difference.

[0208] Since the mounting shell 21 is not deformed on the left side of the upper crossbeam 216, the portion of the support member 233 opposite to the left side of the lower crossbeam 217 will be twisted and deformed toward one side of the cavity 214 of the mounting shell 21, so that the left side of the touch module 23a on the ground side (corresponding to the position N of the lower crossbeam 217) moves toward one side of the cavity 214 of the mounting shell 21, so that the step difference between the left side of the touch module 23a on the ground side and the mounting shell 21 increases and is significantly greater than the step difference between the right side of the touch module 23a on the ground side and the mounting shell 21. This will not only cause the initial step difference between the left side of the touch module 23a on the ground side and the mounting shell 21 to be greater than the design step difference mentioned above, but also cause the step difference uniformity between the left and right sides of the touch module 23a on the ground side and the mounting shell 21 to be poor.

[0209] When the initial step difference is greater than the designed step difference, the user generally describes the electronic device 100 at the touch module 23a as having a large gap. When the step difference uniformity between the left and right sides of the touch module 23a and the mounting shell 21 is poor, the user generally describes the electronic device 100 at the touch module 23a as having an uneven gap.

[0210] Similarly, when the mounting shell 21 is deformed at the position (position M) on the right side of the upper crossbeam 216, the touch module 23a will be driven to move toward one side of the cavity 214 of the mounting shell 21 in the Z direction. At this time, the portion of the support member 233 opposite to the left side of the lower crossbeam 217 will be twisted and deformed toward one side of the outer surface of the mounting shell 21, so that the touch module 23a on the left side of the ground side (corresponding to the position N of the lower crossbeam 217) moves toward one side of the outer surface of the mounting shell 21. This will also cause the problem of poor uniformity of the step difference between the left and right sides of the touch module 23a on the ground side and the mounting shell 21.

[0211] The present application simulates the step difference between the left and right sides of the touch module 23a on the ground side and the mounting shell 21 in the related art when the right side of the upper cross beam 216 undergoes convex female deformation and convex male deformation respectively.

[0212] Fig.18 The figure shows a simulation diagram of the step difference between the left and right sides of the touch module 23a and the mounting shell 21 in the related art when the right side of the upper crossbeam 216 of the mounting shell 21 is deformed. Fig.18 As shown, when the M position on the right side of the upper crossbeam 216 of the mounting shell 21 undergoes a convex female deformation of 0.3 mm, the step difference between the touch module 23a on the left side of the ground side corresponding to the lower crossbeam 217 (P position) and the mounting shell 21 is 0.41 mm, which is greater than the designed step difference of 0.2 mm. The step difference between the touch module 23a on the right side of the ground side corresponding to the lower crossbeam 217 (Q position) and the mounting shell 21 is 0.15 mm, which is less than the designed step difference of 0.2 mm. The step difference unevenness between the left and right sides of the ground side of the touch module 23a and the mounting shell 21 is 0.26 mm. The step difference unevenness refers to the difference in the step difference between the left and right sides of the ground side of the touch module and the mounting shell 21.

[0213] Fig.19 FIG. 2 shows a schematic diagram of a simulation of the step difference between the left and right sides of the touch module 23a and the mounting shell 21 when the right side of the upper crossbeam 216 of the mounting shell 21 undergoes a convex deformation. Fig.19 As shown, when the M position on the right side of the upper crossbeam 216 of the mounting shell 21 undergoes a convex male deformation of 0.3 mm, the step difference between the touch module 23a on the left side of the ground side corresponding to the lower crossbeam 217 (P position) and the mounting shell 21 is 0.12 mm, which is less than the designed step difference of 0.2 mm. The step difference between the touch module 23a on the right side of the ground side corresponding to the lower crossbeam 217 (Q position) and the mounting shell 21 is 0.17 mm, which is less than the designed step difference of 0.2 mm. The step difference unevenness between the left and right sides of the ground side of the touch module 23a and the mounting shell 21 is 0.05 mm.

[0214] To this end, the support member 233 of the touch module 23 provided in the present application includes a first support plate 2331 and a second support plate 2332 arranged at intervals. By setting the first support plate 2331 and the second support plate 2332 at intervals in the touch module 23, it is possible to solve the problems of the existing touch module 23a having an excessively large initial step difference on the ground side, poor step difference uniformity between the left and right sides of the touch module 23a on the ground side and the mounting shell 21, and inconsistent pressing force values ​​on the left and right sides of the touch module 23a.

[0215] The structure of the touch module 23 is further described below with reference to the accompanying drawings.

[0216] Fig. 20 The structure of the touch module 23 on the housing is shown in FIG. Figure 2 . See Fig. 20 As shown, the support member 233 may include a first support plate 2331 and a second support plate 2332. The first support plate 2331 and the second support plate 2332 are spaced apart along the width direction (X direction) of the touch circuit board 232. That is, the support member 233 is designed to be disconnected between the first support plate 2331 and the second support plate 2332. The first support plate 2331 and the second support plate 2332 are both bonded to the touch circuit board 232 so as to achieve the connection between the first support plate 2331 and the second support plate 2332 and the touch circuit board 232, so that the first support plate 2331 and the second support plate 2332 can be supported on the second surface of the touch circuit board 232. For example, the first support plate 2331 and the second support plate 2332 can be bonded to the touch circuit board 232 through a second adhesive layer 238.

[0217] Continue to see Fig. 20 , the rotating member 234 is located on a side of the first support plate 2331 away from the second support plate 2332. Specifically, the first mounting portion 2333 is located on a side of the first support plate 2331 away from the second support plate 2332. The rotating member 234 can be connected to the first mounting portion 2333 of the first support plate 2331. The side of the second support plate 2332 away from the first support plate 2331 is elastically abutted against the shell. Specifically, the first elastic member 237 can be installed on a side of the second support plate 2332 away from the first support plate 2331, so as to realize the elastic abutment between the second support plate 2332 and the shell.

[0218] When one side (for example, the right side) of the upper beam 216 of the mounting shell 21 in the shell body is deformed by the convex female, resulting in the problem of inconsistent deformation degree on the left and right sides of the upper beam 216, since the first support plate 2331 is installed on the upper beam 216 through the rotating member 234, the first support plate 2331 will move relative to the mounting shell 21 toward the outer surface of the mounting shell 21 along the Z direction. At this time, since the support member 233 is a disconnected design, and the second support plate 2332 and the first support plate 2331 are both arranged on the touch circuit board 232, the right side of the second support plate 2332 will also move relative to the mounting shell 21 toward the outer surface of the mounting shell 21 along the Z direction together with the first support plate 2331 under the drive of the touch circuit board 232. However, since the support member 233 is a disconnected design, it is difficult for the twisting force of the first support plate 2331 to be transmitted to the left side of the second support plate 2332. Furthermore, since the rigidity of the touch circuit board 232 is relatively poor, the second support plate 2332 is also less likely to be twisted and deformed due to the influence of the circuit board.

[0219] Similarly, when one side (for example, the right side) of the upper beam 216 of the mounting shell 21 in the housing is deformed convexly, resulting in the problem that the deformation degrees of the left and right sides of the upper beam 216 are inconsistent, the first support plate 2331 will move relative to the mounting shell 21 toward one side of the cavity 214 of the mounting shell 21 along the Z direction. Driven by the touch circuit board 232, the right side of the second support plate 2332 will also move relative to the mounting shell 21 toward one side of the cavity 214 of the mounting shell 21 along the Z direction together with the first support plate 2331. Driven by the touch circuit board 232, the second support plate 2332 is also less likely to be twisted and deformed.

[0220] Therefore, the touch module 23 of the present application can solve the problem of increased initial step difference between the touch module 23 and the mounting shell 21 on the left and right sides of the ground side due to the deformation of the upper beam 216 by setting the first support plate 2331 and the second support plate 2332 at intervals, and improve the problem of poor step difference uniformity between the touch module 23 on the left and right sides of the ground side.

[0221] Furthermore, the interval arrangement of the first support plate 2331 and the second support plate 2332 can also solve the problem of inconsistent pressing force values ​​on the left and right sides of the touch module 23 caused by inconsistent deformation degrees on the left and right sides of the upper crossbeam 216 .

[0222] In addition, since the support member 233 is a disconnected design, the weight of the touch module 23 can be reduced.

[0223] The present application simulates the step difference between the left and right sides of the touch module 23 on the ground side and the mounting shell 21 when the right side of the upper cross beam 216 undergoes convex female deformation and convex male deformation respectively.

[0224] Fig.21 2 shows a simulation diagram of the step difference between the left and right sides of the touch module 23 and the mounting shell 21 in the related art when the right side of the upper crossbeam 216 of the mounting shell 21 undergoes convex female deformation. Fig.21 As shown, similarly, when a convex female deformation of 0.3 mm occurs at the M position on the right side of the upper crossbeam 216 of the mounting shell 21, the step difference between the touch module 23 on the left side of the ground side corresponding to the lower crossbeam 217 (P position) and the mounting shell 21 is 0.18 mm, close to the designed step difference of 0.2 mm. The step difference between the touch module 23 on the right side of the ground side corresponding to the lower crossbeam 217 (Q position) and the mounting shell 21 is 0.23 mm, close to the designed step difference of 0.2 mm. The step difference unevenness between the left and right sides of the ground side of the touch module 23 and the mounting shell 21 is 0.05 mm.

[0225] Fig. 22 FIG. 2 shows a schematic diagram of the simulation of the step difference between the left and right sides of the touch module 23 and the mounting shell 21 in the related art when the right side of the upper crossbeam 216 of the mounting shell 21 undergoes convex deformation. Fig. 22 As shown, similarly, when a convex male deformation of 0.3 mm occurs at the M position on the right side of the upper crossbeam 216 of the mounting shell 21, the step difference between the touch module 23 on the left side of the ground corresponding to the lower crossbeam 217 (P position) and the mounting shell 21 is 0.19 mm, close to the designed step difference of 0.2 mm. The step difference between the touch module 23 on the right side of the ground corresponding to the lower crossbeam 217 (Q position) and the mounting shell 21 is 0.23 mm, close to the designed step difference of 0.2 mm. The unevenness of the step difference between the left and right sides of the ground side of the touch module 23 and the mounting shell 21 is 0.04 mm.

[0226] It can be seen that the present application can better solve the problem of increased initial step difference between the touch module 23 and the mounting shell 21 on the left and right sides of the ground side due to the deformation of the upper beam 216 by setting the first support plate 2331 and the second support plate 2332 at a distance, and improve the problem of poor step difference uniformity between the left and right sides of the ground side of the touch module 23.

[0227] Moreover, when the deformation degree on the left and right sides of the upper crossbeam 216 is inconsistent, the initial step difference between the touch module 23 and the mounting shell 21 is closer to the designed step difference, and the step difference between the left and right sides of the touch module 23 on the ground side and the mounting shell 21 has better uniformity.

[0228] When the touch module 23 is installed on the mounting shell 21, the mounting shell 21 needs to be installed on the bottom shell of the body shell. Among them, the deformation of the support member 233, the mounting shell 21 and the bottom shell are all controlled by tolerance.

[0229] The deformation of the lock ear 4, the deformation of the support member 233, the design height of the touch switch 2321, the deformation of the mounting shell 21, the deformation of the bottom shell, etc. in the touch module 23a of the related art will affect the assembly of the support member 233 on the mounting shell 21, and the position of the touch switch 2321 relative to the protrusion 2121 on the mounting shell 21. When the design height of the touch switch 2321 remains unchanged, the matching dimensions (such as deformation degree and size) between the support member 233, the lock ear 4, the mounting shell 21 and the bottom shell will affect the position of the touch switch 2321 relative to the protrusion 2121 on the mounting shell 21. When the matching dimensions between the support member 233, the lock ear 4, the mounting shell 21 and the bottom shell are at the limit tolerance, it will result in that when the touch module 23a is not pressed, the touch switch 2321 is directly pre-pressed by the protrusion 2121, or there is a gap between the touch switch 2321 and the protrusion 2121.

[0230] For example, when the lock ear 4 or the upper crossbeam 216 is deformed toward the side of the cavity 214 of the mounting shell 21, the touch module 23a will move downward along the Z direction, and the touch switch 2321 may be pre-pressed by the protrusion 2121. For example, when the lock ear 4 or the upper crossbeam 216 is deformed toward the side of the outer surface of the mounting shell 21, the touch module 23a will move upward along the Z direction, and there may be a gap between the touch switch 2321 and the protrusion 2121.

[0231] If the touch switch 2321 in the related art is directly pre-pressed by the protrusion 2121 when the touch module 23a is not pressed, then when the touch module 23a is pressed, the touch switch 2321 is pre-pressed, resulting in a portion of the pressing stroke of the touch switch 2321 being eaten up, resulting in a small pressing force value feedback and a short stroke of the touch module 23. The intuitive feeling of the user experience of the touch module 23a is that there is no pressing force value feedback, which is mainly described as the touch module 23 is stuck and the pressing spring is weak.

[0232] If there is a gap between the touch switch 2321 and the raised portion 2121 when the touch module 23a in the related art is not pressed, then when the touch module 23a is pressed, the touch switch 2321 will first move along the Z direction to contact the raised portion 2121. During this displacement process, the feedback of the pressing force value only includes the superposition of the deformation force of the spring 5 and the deformation force of the lock ear 4. After the touch switch 2321 contacts the raised portion 2121, the touch module 23a is pressed again, and the feedback of the pressing force value is the superposition (coupling) of the normal deformation force of the touch switch 2321, the deformation force of the spring 5, and the deformation force of the lock ear 4. In this way, when the touch switch 2321 is initially moved, the pressing force value fed back by the touch module 23a is relatively small, and the user experience is that the touch module 23a is running empty at the beginning of the pressing process. The user's intuitive feeling is that the touch module 23a is loose and there is an abnormal sound when pressing, which is a poor experience.

[0233] The present application replaces the lock ear 4 in the touch module 23a of the related technology with a rotating part 234, thereby eliminating the influence of the deformation of the lock ear 4 on the matching dimensions between the support member 233, the lock ear 4, the mounting shell 21 and the bottom shell, so as to avoid the matching dimensions between the support member 233, the lock ear 4, the mounting shell 21 and the bottom shell being in the extreme tolerance due to the deformation of the lock ear 4, so as to avoid the touch switch 2321 being directly pre-pressed by the protrusion 2121 when the touch module 23a is not pressed, which can solve the problem of weak pressing elasticity and the problem of empty pressing caused by the gap between the touch switch 2321 and the protrusion 2121.

[0234] Fig.23 Shows Fig.16 Magnified view at F. See Fig.23 Combined with Fig. 20 As shown, the support member 233 has a second elastic member 239 on one side facing the touch circuit board 232. For example, the second elastic member 239 can be an elastic member structure such as foam or shrapnel 5. The structure of the second elastic member 239 and the touch module 23 is further described below using foam as an example.

[0235] The second elastic member 239 is constructed to elastically abut against the shell when the touch unit is installed in the shell, and is in a pre-stressed state (pre-pressed state). That is to say, when the touch unit is installed in the shell, the second elastic member 239 elastically abuts against the shell and is in a pre-stressed state to eliminate the gap between the touch switch 2321 and the protrusion 2121, thereby solving the problem of pressing and idling mentioned above. The pre-stressed state of the second elastic member 239 can be understood as a state in which the second elastic member 239 and the shell are in an interference fit. Specifically, the second elastic member 239 can be in an interference fit with the mounting shell 21 in the shell, and elastically abut against the mounting shell 21.

[0236] It should be noted that by controlling the pre-compression degree of the second elastic member 239, the contact between the touch switch 2321 and the protrusion 2121 can be controlled, and the protrusion 2121 is not pre-compressed. In the present application, the pre-compression degree of the second elastic member 239 is not further limited.

[0237] Continue to see Fig.23 Combined with Fig. 20 The second elastic member 239 can be located on a side of the support member 233 adjacent to the touch switch 2321, so that when the second elastic member 239 elastically abuts against the shell, the support member 233 and the touch circuit board 232 can move toward one side of the protrusion 2121 to eliminate the gap between the touch switch 2321 and the protrusion 2121.

[0238] Continue to see Fig.23The support member 233 may have a second mounting portion 2335. The second mounting portion 2335 is exposed on the side of the touch circuit board 232. The housing has a third slot 2154. The second mounting portion 2335 is located inside the third slot 2154. The second elastic member 239 is located on the side of the second mounting portion 2335 facing the touch circuit board 232, and elastically abuts against the slot wall of the third slot 2154. In this way, by setting the second mounting portion 2335, the second elastic member 239 can be assembled on the support member 233 without affecting the installation of the touch circuit board 232 in the opening 213 of the mounting shell 21, and elastically abuts against the housing in the third slot 2154.

[0239] It should be noted that the third groove 2154 can be located in the mounting shell 21 and communicate with the opening 213 in the mounting shell 21 for mounting the touch module 23, so that when the touch unit is installed in the opening 213, the second mounting portion 2335 can be located inside the third groove 2154 to achieve elastic abutment between the second elastic member 239 and the mounting shell 21.

[0240] The third groove 2154 can be formed by the metal shell 211 and the plastic shell 212 in the installation shell 21, so as to simplify the processing technology of the installation shell 21. The second elastic member 239 can elastically abut against the metal shell 211 and have interference fit.

[0241] The second mounting portion 2335 is a protruding structure on the side edge of the support member 233 , so that the second mounting portion 2335 can be located inside the third groove 2154 , which is beneficial to miniaturization of the support member 233 and the touch module 23 .

[0242] The second elastic member 239 may be located on a side of the second support plate 2332 away from the first support plate 2331, and connected to the second support plate 2332, so as to fix the second elastic member 239 on the support member 233. For example, when the second elastic member 239 is foam, the second elastic member 239 may be connected to the second support plate 2332 by bonding, and fixed on the second support plate 2332.
