The embodiment of the application provides electronic equipment and a keyboard assembly, which are beneficial to reducing the weight of the keyboard assembly and improving the portability of the whole electronic equipment.

The first aspect of the application provides an electronic device comprising a display assembly and a keyboard assembly.

The keyboard assembly is in communication with the display assembly. The keyboard assembly includes a housing and a keyboard. The housing includes a top plate. The top plate includes a first relief aperture. The keyboard comprises a base part, a metal reinforcing frame and keys. The base member is disposed within the housing. The key is connected with the base part. All keys are located in the first avoidance holes. The key comprises a key cap. Along the thickness direction of the keyboard, the metal reinforcement frame is arranged on one side of the base part facing the keycap. The metal reinforcement frame includes a second avoidance hole. The key is arranged corresponding to the second avoidance hole. The orthographic projection of the second avoidance hole is positioned in the orthographic projection of the keycap. The keycap comprises a cap peak positioned above the metal reinforcing frame. A gap is arranged between the adjacent hat brim. The metal reinforcing frame comprises a separation strip positioned below the gap. The width of the separation strip is larger than the width of the gap. The front projection of the cap peak and the front projection of the separation strip have overlapping areas. Along the thickness direction of the keyboard, the outer edge of the metal reinforcing frame is positioned below the top plate.

The electronic device of the embodiment of the application comprises a keyboard component. The keyboard assembly includes a housing and a keyboard. The keyboard includes a plurality of keys having key caps. The roof of shell sets up the first hole of dodging that is used for dodging all buttons. In the keyboard of the embodiment of the application, the space between the key caps is smaller so as to reduce the overall size of the key area, thereby being beneficial to reducing the overall size of the keyboard assembly and improving the portability of the keyboard assembly. The keyboard also includes a base member and a metal reinforcing frame. The metal reinforcement frame is arranged on one side of the base part facing the keycap. The metal reinforcement frame can be used for improving the overall rigidity of the keyboard so as to improve the overall deformation resistance of the keyboard and reduce the possibility of structural damage of the keyboard caused by bending or pulling. Because the rigidity of the whole keyboard is relatively high, the keyboard can be carried without the top plate of the shell, and the top plate of the shell and the keyboard can be mutually independent. The outer shell also has a decorative effect so as to shield internal electronic devices or structural parts and improve the appearance attractiveness of the keyboard assembly. In the keyboard component provided by the embodiment of the application, the top plate of the shell does not need to be processed to form a grid structure, so that a connecting frame does not need to be correspondingly arranged, the weight of the keyboard component is reduced, and the overall portability of the electronic equipment is improved.

In one possible embodiment, the key cap includes a pressing plate and a shutter. The baffle is arranged below the pressing plate. The part of the pressing plate beyond the baffle forms a hat brim. The baffle plate and the separation strip are provided with a space therebetween.

The baffle can be arranged facing the gap between the hat brim and the separation strip, so that when an external object (such as dust) enters from the gap between the adjacent hat brim, the baffle can play a role in blocking the dust and other objects, and the dust and other objects can stay in the space surrounded by the baffle, the separation strip and the hat brim. The baffle and the separation strip can effectively reduce the possibility that objects such as dust enter into areas such as the base part.

In one possible embodiment, the visor and the baffle on opposite sides of the separator bar form a relief space. Along the thickness direction of the keyboard, the separation strip is arranged facing the avoidance space.

Because the avoidance space is formed between the keycap and the keycap, the downward-moving cap peak and the baffle plate can not be contacted with the separation strip, and the situation that the cap peak and the separation strip and the baffle plate and the separation strip are interfered in position is avoided. In addition, objects entering from gaps between adjacent hat brim can stay in the avoidance space, are difficult to enter into the base part and other areas from the avoidance space, and meanwhile, the objects entering from the avoidance space are taken out from the avoidance space by using tools conveniently, so that the cleaning convenience of the keyboard is improved.

In one possible embodiment, a portion of the separator bar is located within the avoidance space. Along the thickness direction of the keyboard, the end surface of the baffle plate, which is far away from the pressing plate, is positioned below the end surface of the separation strip, which faces the pressing plate.

The baffle can shelter from the gap between brim of a hat and the parting bead to form the gap between baffle and the parting bead, be favorable to prolonging external object and enter into the route in base part etc. region, increase external object and enter into the degree of difficulty in base part etc. region, be favorable to further reducing objects such as dust and enter into the possibility in base part etc..

In one possible embodiment, the baffle is annular, so that the baffle can act as a barrier at any circumferentially-oriented position.

In one possible embodiment, the upper surface of the key cap is flush with the upper surface of the top plate so that the keys can fully utilize the space within the housing to facilitate reducing the thickness of the keyboard.

In one possible embodiment, the spacing between adjacent visors is 0.3 mm to 0.6 mm.

In one possible embodiment, the keyboard further comprises a cover frame. The cover frame is arranged on the surface of the metal reinforcing frame facing the keycap along the thickness direction. The cover frame includes a third relief aperture. The second avoidance hole is arranged corresponding to the third avoidance hole.

On the one hand, the cover frame can strengthen the metal reinforcement frame, so that the integral structure formed by connecting the cover frame and the metal reinforcement frame has relatively high deformation resistance, and the possibility of warping and deformation of the metal reinforcement frame is reduced. On the other hand, the cover frame can be used for shielding the surface of the metal reinforcing frame facing the keycap so as to play a role in protection and reduce the possibility of scraping the surface of the metal reinforcing frame facing the keycap. In yet another aspect, the cover frame may function as a decoration to enhance the delicacy of the keyboard.

In one possible embodiment, the outer edge of the cover frame is located below the top plate. The top plate is in contact with a surface of the cover frame facing the key cap.

In one possible embodiment, the material of the cover frame is plastic or metal.

In one possible embodiment, the base member includes a circuit board and a metal connection plate. Along the thickness direction of the keyboard, the circuit board and the metal connecting plate are arranged in a lamination way. The key also comprises a pressing bracket. The metal connecting plate is rotatably connected with the pressing support. The keycap is rotatably connected with the pressing support. The pressing support is arranged below the keycap.

In one possible embodiment, the base member further comprises a bottom stiffening plate. The circuit board and the metal connecting plate are arranged on one side of the bottom reinforcing plate facing the keycap.

The bottom reinforcing plate and the metal connecting plate can be used together for improving the deformation resistance of the base part, so that the possibility that the circuit board is bent or pulled to cause fracture of the circuit board is further reduced.

In one possible embodiment, the base member further comprises a backlight module. Along the thickness direction of the keyboard, the circuit board, the metal connecting plate and the backlight module are arranged in a laminated mode.

The backlight module can be used for providing backlight for the keys, so that in the environment with darker light, a user can clearly observe the corresponding keys, the possibility of misoperation of the keys is reduced, and the input accuracy and the input efficiency are improved.

In one possible embodiment, the base member further comprises an insulating plate. Along the thickness direction of the keyboard, the circuit board, the metal connecting plate and the insulating plate are arranged in a laminated way.

In one possible embodiment, the keyboard further comprises a connector. The connecting piece comprises a first component and a second component. The first component is connected with the metal reinforcement frame. The base member has a mounting hole. The first component is inserted into the mounting hole. The first and second members are interconnected to connect the metal reinforcement frame and the base member. The second part is pressed against the base part to apply compressive stress to the base part towards the metal reinforcing frame.

In one possible embodiment, the keyboard further comprises a connector. The connecting piece is connected with the metal reinforcing frame. The connecting piece is a hot melt piece. The base member has a mounting hole. The connecting piece is inserted into the mounting hole. The connector has a cap portion.

The convex part is connected with the connecting piece. The convex part is propped against the surface of the metal reinforcing frame, which is opposite to the keycap.

The metal reinforcing frame is connected to the convex part on the metal connecting plate through the connecting piece. The convex part of the metal connecting plate can be propped against the surface of the metal reinforcing frame, which is opposite to the keycap, so that the metal connecting plate can provide supporting force for the metal reinforcing frame through the convex part, thereby improving the deformation resistance of the metal reinforcing frame. Because in the base part, the rigidity of the metal connecting plate is relatively high, the connecting piece is connected with the convex part, and the metal connecting plate is not easy to deform under the condition that the connecting piece applies acting force to the metal connecting plate, so that the connection stability of the metal reinforcing frame and the base part is improved.

A second aspect of the application provides a keyboard assembly comprising a housing and a keyboard. The housing includes a top plate. The top plate includes a first relief aperture. The keyboard comprises a base part, a metal reinforcing frame and keys. The base member is disposed within the housing. The key is connected with the base part.

The keyboard assembly 30 may provide input instructions to the electronic device 10, and the electronic device 10 performs associated operations responsive to the input instructions based on the input instructions of the keyboard assembly 30.

Fig. 4 schematically shows a partial structure of the keyboard assembly 30. Fig. 5 schematically shows a partially exploded construction of the keyboard assembly 30. Referring to fig. 4 and 5, the keyboard assembly 30 of the embodiment of the present application includes a keyboard 40 and a housing 50. The keyboard 40 is disposed in the housing 50. The keyboard 40 of the embodiment of the present application includes a base member 41. The base member 41 is disposed within the housing 50. Illustratively, the material of the housing 50 may be, but is not limited to, aluminum or an aluminum alloy. Illustratively, the base member 41 may include a circuit board 411 and a metal connection board 412. Along the thickness direction Z of the keyboard 40, the circuit board 411 and the metal connection board 412 are stacked. For example, the circuit board 411 may be located above the metal connection board 412. Alternatively, the metal connection plate 412 may be located above the circuit board 411. The metal connection plate 412 may be advantageous to improve the deformation resistance of the entire base member 41, and reduce the possibility of the circuit board 411 bending or being pulled to break itself. Illustratively, the circuit board 411 may be a flexible circuit board. The material of the metal connection plate 412 may be steel, aluminum or an aluminum alloy. For example, the metal connection plate 412 may be a steel sheet. The thickness of the metal connection plate 412 may be 0.3 mm to 0.4 mm. For example, the thickness of the metal connection plate 412 may be 0.3 millimeters.

Referring to fig. 5, a keyboard 40 according to an embodiment of the present application includes keys 42. A plurality of keys 42 may be provided on the base member 41. The base member 41 and the keys 42 may be stacked. The base member 41 may provide support for each key 42. Keys 42 may include numeric keys, function keys (e.g., enter key, delete key, insert key, etc.), alphabetic keys (alphabetic "A" key to alphabetic "Z" key), and the like. Illustratively, the keys 42 themselves may be divided into single-time keys and multiple-time keys according to their size. Single-fold keys refer to keys 42 on keyboard 40 that are square, such as individual letter keys. The multiple keys are keys 42 other than the single key, for example, a space key, an Enter key, and a Shift key 42.

Fig. 6 schematically shows a partially cut-away structure of the keyboard 40. Referring to fig. 6, the key 42 may include a pressing bracket 421 and a key cap 422. The pressing bracket 421 may be rotatably coupled with the key cap 422 and the base member 41, respectively. For example, the pressing bracket 421 may be rotatably coupled with the key cap 422 and the metal connection plate 412, respectively. The pressing bracket 421 is disposed under the key cap 422 in the thickness direction Z of the keyboard 40. The pressing bracket 421 is configured to provide good support for the key cap 422 so as to enable the key cap 422 to be pressed with balanced pressing stress, so that the user's finger can press the key cap 422 with a fixed pressure at any position on the key cap 422, and the possibility of uneven pressure or seizing of the key cap 422 is reduced. The key cap 422 has a pressing stroke in the thickness direction Z of the keyboard 40. The pressing stroke refers to a distance between an upper surface when the key cap 422 is not pressed and an upper surface when pressed and pressed to the lowest position. Illustratively, the key cap 422 may be rectangular.

Illustratively, the pressing bracket 421 may include a scissor assembly. Illustratively, the scissor assemblies include an outer scissor 421a and an inner scissor 421b. The outer and inner scissor legs 421a and 421b are interdigitated and rotatably coupled. The lower ends of the outer and inner scissor legs 421a and 421b are rotatably connected with the metal connection plate 412. The upper ends of the outer and inner scissor legs 421a and 421b are rotatably connected to the key cap 422. In some examples, outer and inner scissor legs 421a, 421b may each be a square frame structure.

Illustratively, the key 42 further includes an elastic member 423. The elastic member 423 is disposed at a side of the key cap 422 facing the circuit board 411. The elastic member 423 is located between the key cap 422 and the circuit board 411. The elastic member 423 serves to provide a resilient force to the key cap 422. When the user presses the key cap 422 downward, the key cap 422 may compress the elastic member 423. When the user releases the key cap 422, the elastic member 423 releases elastic potential energy to rebound to drive the key cap 422 to move upward. Illustratively, the end of the elastic member 423 near the circuit board 411 is connected to the surface of the circuit board 411 facing the key cap 422. Illustratively, the elastic member 423 is a flexible structure. The material of the elastic member 423 may be selected from a silicone rubber or a rubber.

Illustratively, the circuit board 411 includes a sense electrode 411a. The key 42 also includes an electrical conductor 424. The conductive body 424 is disposed on a side of the elastic member 423 near the circuit board 411. Illustratively, sense electrode 411a is spaced a predetermined distance from electrical conductor 424 such that a capacitance may be formed therebetween. When the user presses or releases the key cap 422, the elastic member 423 moves down or up to change the capacitance value of the capacitor. The keyboard 40 receives the capacitance value change signal to identify the position of the struck key 42 to execute the corresponding input instruction. Illustratively, the material of the electrical conductor 424 may be, but is not limited to, a carbon powder layer or a carbon powder-containing layer structure.

In the related art, the keyboard in the electronic device 10 is an "island" keyboard. The spacing between the key caps of an "island" keyboard is relatively large (e.g., the spacing between the key caps may be 3 millimeters) so that the individual key caps remain relatively independent. In order to match the independent setting of each key cap, the keyboard subassembly includes a plurality of holes of dodging. Each keycap is correspondingly provided with an avoidance hole. The avoidance holes penetrate through the shell and the connecting frame, so that grid structures are formed on the shell and the connecting frame respectively. The shape of the connecting frame is matched with that of the shell, and the connecting frame and the shell are mutually overlapped. The material of the shell can be aluminum or aluminum alloy, and the material of the connecting frame can be plastic or metal. The connection frame may be adhered to the inner side of the housing by an adhesive. The thickness of the housing is relatively small. The plurality of avoidance holes penetrate through the design of the shell, so that the rigidity of the area with the grid structure on the shell is relatively weak, and collapse and deformation are easy to occur. The connecting frame is mainly used for supporting the shell and avoiding the situation that the grid structure of the shell collapses and deforms. The keyboard may be connected to the connection frame. For example, the keyboard includes a base member located within the housing. A connecting frame is arranged between the base part and the shell. The base part of the keyboard and the connecting frame can be connected through structural members such as rivets, screws and the like. The connecting frame belongs to a connecting component and is used for realizing the connection between the keyboard and the shell. The housing and the connecting frame can carry a keyboard. It should be noted that the connection frame does not belong to the components in the keyboard. The connecting frame and the keyboard belong to parts which are arranged independently. The grid structure on the housing includes frame bars. The grid structure on the housing includes longitudinal and transverse frame bars surrounding the dodge apertures. A frame strip is arranged between the two key caps. The size of each keycap is smaller than the size of the avoidance hole, so that the width of the frame strip of the grid structure is smaller than the interval between the keycaps. Along the thickness direction of the keyboard, the front projection of the keycap is not overlapped with the front projection of the frame strip, and the front projection of the keycap is not overlapped with the front projection of the connecting frame. When the key cap is knocked, the key cap can sink into the avoidance hole and cannot be contacted with the shell and the connecting frame to cause position interference. However, in the electronic device 10 including the "island type" keyboard, a grid structure needs to be formed on the housing, and a connection frame needs to be correspondingly disposed, so that the keyboard assembly has relatively large weight, and the use experience of the electronic device 10 is affected.

In the electronic device 10 provided by the embodiment of the application, the key caps 422 of the keyboard 40 are relatively smaller in interval between the key caps 422 to form a small-gap keyboard, so that the integrity of all the key caps 422 is stronger and the attractiveness is higher. The small gap keyboard and the island type keyboard belong to keyboards with different structures. The spacing between keycaps 422 and 422 in a small gap keyboard is less than the spacing between keycaps 422 and 422 in an "island" keyboard. Only one first escape hole is provided in the housing 50 according to the embodiment of the present application corresponding to all the keys 42. Therefore, the casing 50 does not need to be processed to form a grid structure, and therefore, a connecting frame does not need to be correspondingly arranged, which is beneficial to reducing the weight of the keyboard assembly 30 and improving the portability of the whole electronic device 10. A metal reinforcing frame is provided in the keyboard 40. The metal reinforcing frame is hidden under the keycap 422, and is not easily observed when the keyboard assembly 30 is viewed from the outside. The metal reinforcement frame may be used to improve the resistance to deformation of the keyboard 40 as a whole.

Referring to fig. 4, 5 and 6, the keyboard assembly 30 of the embodiment of the present application includes a keyboard 40 and a housing 50. The housing 50 includes a top plate 51. The top plate 51 includes a first escape aperture 50a. When the keyboard assembly 30 is in use, the top plate 51 of the housing 50 faces upward. The keyboard 40 includes a base member 41, a metal reinforcing frame 43, and keys 42. The base member 41 is disposed within the housing 50. The housing 50 may obscure the base member 41 when viewed from the outside of the keyboard assembly 30 so that the base member 41 is not easily visible. All keys 42 on the keyboard 40 are located in the first avoiding holes 50a, i.e. in the thickness direction Z of the keyboard 40, and the orthographic projection of all keys 42 is located in the orthographic projection of the first avoiding holes 50a.

The key 42 includes a key cap 422. The key cap 422 is used to receive a pressing force from a finger. The user's finger may apply a pressing force to the key cap 422 in order to press the corresponding key 42. The metal reinforcing frame 43 is provided on a side of the base member 41 facing the key cap 422 in the thickness direction Z of the keyboard 40. The metal reinforcing frame 43 may be connected to the base member 41. The metal reinforcement frame 43 belongs to the parts of the keyboard 40 itself, i.e. the metal reinforcement frame 43 is included in the assembled keyboard 40. The metal reinforcing frame 43 may increase the overall rigidity of the keyboard 40 to increase the deformation resistance of the keyboard 40. Illustratively, the material of the metal reinforcement frame 43 includes, but is not limited to, steel, aluminum, or aluminum alloy.

Fig. 7 schematically shows the structure of the metal reinforcing frame 43. Fig. 8 is an enlarged view at W in fig. 7. Referring to fig. 6, 7 and 8, the metal reinforcing frame 43 includes a second escape hole 43a. The number of the second escape holes 43a is plural. The key 42 is disposed corresponding to the second escape hole 43a. For example, one key 42 may be disposed corresponding to one second escape hole 43a. The front projection of the second escape hole 43a is located within the front projection of the key cap 422 in the thickness direction Z of the keyboard 40. The key cap 422 has a size larger than that of the second escape hole 43a. The key cap 422 may completely block the second escape hole 43a. When viewed along the thickness direction Z of the keyboard 40, the second avoidance holes 43a are hidden under the key caps 422, so that the second avoidance holes 43a are not easily observed.

The keycap 422 includes a bill 422a positioned over the metal reinforcing frame 43. A space is provided between the cap peak 422a and the metal reinforcing frame 43 in the thickness direction Z of the keyboard 40. When the key cap 422 is pressed to the lowest position, the cap peak 422a and the metal reinforcing frame 43 may not be in contact with each other. With a gap 100 between adjacent visors 422a. The keycaps 422 are relatively small in spacing from one another, so that each key 42 is compactly laid out, which is advantageous for downsizing the overall size of the keyboard 40. Illustratively, the spacing between adjacent visors 422a is 0.3 millimeters (mm) to 0.6 mm. For example, the spacing between adjacent visors 422a is 0.3 millimeters or 0.4 millimeters.

The metal reinforcement frame 43 includes a separation bar 431. The separation bar 431 is located below the gap 100 between the visors 422a in the thickness direction Z of the keyboard 40. Illustratively, the metal reinforcement frame 43 includes a longitudinal separator bar 431 and a transverse separator bar 431. The longitudinal separator 431 extends in the width direction Y of the keyboard 40, while the transverse separator 431 extends in the length direction X of the keyboard 40. The longitudinal separating bars 431 and the transverse separating bars 431 are alternately arranged around the second escape holes 43 a. The width of the separator strip 431 is greater than the width of the gap 100 between adjacent cap visors 422a. The width of the separation bar 431 and the width of the gap 100 refer to a dimension measured in the width direction Y of the keyboard 40 or the length direction X of the keyboard 40. For example, the width of the lateral separator bar 431 refers to a dimension measured in the width direction Y of the keyboard 40. The width of the longitudinal separator bar 431 refers to the dimension measured along the length direction X of the keyboard 40. The separating strip 431 can shield the underlying base member 41, so that when viewed through the gap 100 between adjacent visors 422a, the underlying separating strip 431 can be observed, and the underlying base member 41 is not easily observed, which is beneficial to improving the aesthetic degree of the keyboard 40. In addition, objects (e.g., dust) falling from the gap 100 between adjacent visors 422a may fall onto the separator 431, and thus the separator 431 may also serve to block objects such as dust from entering the area of the base member 41 or the like.

In the thickness direction Z of the keyboard 40, the front projection of the cap bill 422a and the front projection of the separator 431 have overlapping areas. The front projection of the bill 422a may be entirely within the front projection of the separator bar 431, or a portion of the front projection of the bill 422a may be within the front projection of the separator bar 431. The two visors 422a on both sides of the separation bar 431 may simultaneously shield one separation bar 431 below.

The outer edge of the metal reinforcing frame 43 is located below the top plate 51 of the housing 50 in the thickness direction Z of the keyboard 40. The top plate 51 of the housing 50 may shield the outer edge of the metal reinforcing frame 43, so that the outer edge of the metal reinforcing frame 43 is not easily observed when being observed from the outside, and the aesthetic degree of the keyboard assembly 30 is improved. Meanwhile, the top plate 51 of the housing 50 can limit the metal reinforcing frame 43, so that the possibility that the metal reinforcing frame 43 enters the first avoiding hole 50a of the top plate 51 is reduced.

Illustratively, the housing 50 may also include side panels 52 and a bottom panel 53 (see fig. 5). The side plate 52 is connected to the top plate 51. The bottom plate 53 is connected to the side plate 52. The keyboard 40 may be coupled to the base 53 to fix the position of the keyboard 40. For example, the base member 41 of the keyboard 40 may be coupled to the bottom panel 53. The keyboard 40 and the top plate 51 may be in a non-connected state, i.e., no connection structure for connecting the keyboard 40 and the top plate 51 is provided between the keyboard 40 and the top plate 51, for example, no fastener, rivet, solder bump or glue for connecting the keyboard 40 and the top plate 51 is provided. The top plate 51 of the housing 50 may be in contact with the keyboard 40. The top plate 51 may also apply compressive stress to the keyboard 40 at the contact area, such as toward the bottom plate 53, to limit the keyboard 40.

The electronic device 10 of the present embodiment includes a keyboard assembly 30. The keyboard assembly 30 includes a keyboard 40 and a housing 50. The keyboard 40 includes a plurality of keys 42 having key caps 422. The top plate 51 of the housing 50 is provided with first escape holes 50a for escaping all the keys 42. In the keyboard 40 of the embodiment of the present application, the spacing between the key caps 422 is smaller, so as to reduce the overall size of the key 42 area, thereby being beneficial to reducing the overall size of the keyboard assembly 30 and improving the portability of the keyboard assembly 30. The keyboard 40 further includes a base member 41 and a metal reinforcement frame 43. The metal reinforcing frame 43 is provided on a side of the base member 41 facing the key cap 422. The metal reinforcement frame 43 may be used to increase the overall rigidity of the keyboard 40 to increase the overall resistance to deformation of the keyboard 40 and reduce the likelihood of structural failure of the keyboard 40 by bending or pulling. Since the rigidity of the entire keyboard 40 including the metal reinforcing frame 43 is relatively high, the keyboard 40 can be carried without the top plate 51 of the housing 50, so that the top plate 51 of the housing 50 and the keyboard 40 can be independent from each other. The housing 50 also has a decorative effect to conceal the internal electronics or structural components and enhance the aesthetic appearance of the keyboard assembly 30. In the keyboard assembly 30 of the embodiment of the present application, the top plate 51 of the housing 50 does not need to be processed to form a grid structure, so that a connecting frame does not need to be correspondingly arranged, which is beneficial to reducing the weight of the keyboard assembly 30 and improving the portability of the whole electronic device 10.

Fig. 9 schematically shows a partially cut-away structure of the keyboard assembly 30. Referring to fig. 6 and 9, the key cap 422 may include a pressing plate 4221 and a blocking plate 4222. The pressing plate 4221 is used to receive a pressing force from a finger. The user's finger may apply a pressing force to the pressing plate 4221 so as to press the corresponding key 42. The shutter 4222 is provided below the pressing plate 4221 in the thickness direction Z of the keyboard 40. When viewed from the outside of the keyboard assembly 30, the shutter 4222 is shielded by the pressing plate 4221, and the shutter 4222 is not easily visible. The portion of the pressing plate 4221 beyond the stopper 4222 forms a visor 422a. The baffle 4222 and the separation strip 431 have a space therebetween, so that position interference between the baffle 4222 and the separation strip 431 is avoided in the process of pressing the key cap 422. In the thickness direction Z of the keyboard 40, the front projection of the barrier 4222 does not overlap with the front projection of the division bar 431, and there is a space between the front projection of the barrier 4222 and the front projection of the division bar 431.

The baffle 4222 may be disposed to face the gap between the visor 422a and the separation bar 431, so that when an external object (e.g., dust) enters from the gap 100 between the adjacent visors 422a, the baffle 4222 may act as a barrier to the dust or the like, so that the dust or the like may remain in the space surrounded by the baffle 4222, the separation bar 431 and the visor 422a. The baffle 4222 and the separation bar 431 may effectively reduce the possibility of objects such as dust entering the area of the base member 41.

Illustratively, the keyboard 40 includes a pressing bracket 421. The pressing plate 4221 is rotatably connected to the pressing bracket 421. The connection point of the pressing plate 4221 and the pressing bracket 421 is located at a side of the blocking plate 4222 facing away from the cap peak 422a, i.e., the connection point is located at an inner side of the blocking plate 4222. The baffle 4222 can block objects such as dust, and effectively reduce the possibility that the objects such as dust enter the area such as the pressing bracket 421 or the base member 41.

Illustratively, the material of the pressing plate 4221 and the material of the baffle 4222 may be both plastics. The pressing plate 4221 and the blocking plate 4222 may be integrally formed.

Illustratively, the upper surface of the key cap 422 is flush with the upper surface of the top plate 51 of the housing 50 so that the keys 42 can fully utilize the space within the housing 50 to facilitate reducing the thickness of the keyboard 40. The upper surface of keycap 422 may be planar. For example, the key cap 422 includes a pressing plate 4221. The upper surface of the pressing plate 4221 is flush with the upper surface of the top plate 51. The upper surface of the pressing plate 4221 may be a plane.

In some examples, referring to fig. 9, the visor 422a and the baffle 4222 on opposite sides of the separation bar 431 form the relief space 200, i.e., adjacent visor 422a and adjacent baffle 4222 may form the relief space 200. The separation bar 431 is disposed facing the escape space 200 in the thickness direction Z of the keyboard 40. The escape space 200 may escape the separation bar 431. When the key cap 422 is pressed, the visor 422a and the stopper 4222 of the key cap 422 are moved downward. Because the avoiding space 200 is formed between the keycaps 422 and the keycaps 422, the downward-moving cap peak 422a and the baffle 4222 do not contact with the separation strip 431, and the situation that the cap peak 422a and the separation strip 431 and the baffle 4222 interfere with the separation strip 431 in position is avoided. In addition, the objects entering from the gaps 100 between the adjacent cap peak 422a can stay in the avoidance space 200, and are not easy to enter the base member 41 and other areas from the avoidance space 200, and meanwhile, the objects entering from the avoidance space 200 are conveniently taken out by using tools, so that the cleaning convenience of the keyboard 40 is improved.

In some examples, fig. 10 schematically shows a partial cross-sectional structure of keyboard assembly 30. Referring to fig. 10, a portion of the separator bar 431 is located within the escape space 200. An end surface of the shutter 4222 away from the pressing plate 4221 is located below an end surface of the partition bar 431 facing the pressing plate 4221 in the thickness direction Z of the keyboard 40. The baffle 4222 can shield the gap between the cap peak 422a and the separation strip 431, and a gap is formed between the baffle 4222 and the separation strip 431, which is beneficial to prolonging the path of external objects entering into the base part 41 and other areas, increasing the difficulty of external objects entering into the base part 41 and other areas, and being beneficial to further reducing the possibility of dust and other objects entering into the base part 41 and other areas.

In some examples, the baffles 4222 are annular, such that the baffles 4222 may act as a stop at any location in the circumferential direction. Illustratively, the second relief hole 43a in the metal reinforcement frame 43 is rectangular. The pressing plate 4221 is rectangular. The baffle 4222 has a rectangular ring structure.

Fig. 11 schematically shows a partially exploded construction of the keyboard assembly 30. Fig. 12 schematically shows a partially cut-away structure of the keyboard assembly 30. Referring to fig. 11 and 12, the keyboard 40 further includes a cover frame 44. The cover frame 44 is disposed on a surface of the metal reinforcing frame 43 facing the key cap 422 in the thickness direction Z of the keyboard 40. The cover frame 44 is located above the metal reinforcing frame 43. The cover frame 44 includes a third escape hole 44a. The second escape holes 43a are provided corresponding to the third escape holes 44a in the thickness direction Z of the keyboard 40. The number of the second escape holes 43a is equal to the number of the third escape holes 44a. The shape of the cover frame 44 matches the shape of the metal reinforcing frame 43. The orthographic projection of the third escape aperture 44a is located within the orthographic projection of the key cap 422 in the thickness direction Z of the keyboard 40. The size of the key cap 422 is larger than the size of the third escape hole 44a. The key cap 422 may completely block the third escape hole 44a. The front projection of the visor 422a has an overlapping area with the front projection of the cover frame 44. When viewed along the thickness direction Z of the keyboard 40, the third avoiding hole 44a is hidden under the key cap 422, so that the third avoiding hole 44a is not easily observed. Illustratively, the second relief hole 43a may be the same size as the third relief hole 44a. In the thickness direction Z of the keyboard 40, the orthographic projection of the second escape hole 43a coincides with the orthographic projection of the third escape hole 44a.

On the one hand, the cover frame 44 can reinforce the metal reinforcing frame 43, so that the integral structure formed by connecting the cover frame 44 and the metal reinforcing frame 43 has relatively high deformation resistance, and the possibility of warping and deformation of the metal reinforcing frame 43 is reduced. On the other hand, the covering frame 44 may be used to shield the surface of the metal reinforcing frame 43 facing the keycap 422, so as to play a protective role, and reduce the possibility of scraping the surface of the metal reinforcing frame 43 facing the keycap 422. In yet another aspect, the cover frame 44 may be decorative to enhance the delicacy of the keyboard 40.

Illustratively, the thickness of the cover frame 44 is less than the thickness of the metal reinforcement frame 43. For example, the thickness of the metal reinforcing frame 43 may be 0.5 mm to 0.7 mm. Specifically, the thickness of the metal reinforcing frame 43 may be 0.6 mm or 0.65 mm. The thickness of the cover frame 44 may be 0.06 to 0.1 millimeters. Specifically, the thickness of the cover frame 44 may be 0.08 millimeters.

Illustratively, the material of the cover frame 44 may be a metallic material. For example, the material of the cover frame 44 may be, but is not limited to, aluminum or an aluminum alloy.

Illustratively, the material of the cover frame 44 may be plastic.

Illustratively, the cover frame 44 is adhered to the surface of the metal reinforcing frame 43 facing the keycap 422.

The outer edge of the cover frame 44 is located below the top plate 51 of the housing 50. The top plate 51 of the housing 50 may shield the outer edge of the cover frame 44 such that the outer edge of the cover frame 44 is not easily observed when being externally observed, improving the aesthetic degree of the keyboard assembly 30. The top plate 51 contacts the surface of the cover frame 44 facing the key cap 422. The top plate 51 may apply compressive stress to the keyboard 40 at the contact area with the cover frame 44, for example, toward the bottom plate 53, to limit the keyboard 40. The cover frame 44 and the top plate 51 may be in a non-connected state, i.e., no connection structure for connecting the cover frame 44 and the top plate 51 is provided between the cover frame 44 and the top plate 51, for example, no fastener, rivet, solder bump or glue for connecting the cover frame 44 and the top plate 51 is provided.

In some examples, fig. 13 schematically shows a partially exploded structure of keyboard assembly 30. Referring to fig. 13, the base member 41 includes a circuit board 411 and a metal connection board 412. Along the thickness direction Z of the keyboard 40, the circuit board 411 and the metal connection board 412 are stacked. The base member 41 also includes a bottom stiffening plate 413. The circuit board 411 and the metal connection board 412 are disposed on a side of the bottom reinforcing plate 413 facing the key cap 422. The circuit board 411, the metal connection board 412, and the bottom reinforcing plate 413 are stacked. The bottom stiffener 413 and the metal connection plate 412 may be used together to increase the resistance to deformation of the base member 41, further reducing the likelihood of the circuit board 411 bending or being pulled to fracture itself.

The circuit board 411 and the metal connection board 412 are disposed between the metal reinforcing frame 43 and the bottom reinforcing plate 413. The metal reinforcing frame 43, the metal connection plate 412, and the bottom reinforcing plate 413 may be used together to increase the rigidity of the entire keyboard 40. Since the metal reinforcing frame 43, the metal connecting plate 412 and the bottom reinforcing plate 413 are simultaneously disposed in the keyboard 40, the thickness of the bottom reinforcing plate 413 itself can be designed to be relatively small, so that the thickness of the keyboard 40 can be reduced under the condition that the overall rigidity of the keyboard 40 meets the requirement, and the light and thin keyboard 40 can be realized.

Illustratively, the thickness of the bottom stiffener 413 may be less than the thickness of the metal stiffener frame 43.

Illustratively, the bottom stiffener 413 has a thickness of 0.3 millimeters to 0.5 millimeters. For example, the thickness of the bottom reinforcing plate 413 is 0.4 mm.

Illustratively, the metal reinforcing frame 43 may be connected to a metal connection plate 412.

Illustratively, the material of the bottom stiffener 413 may be a metallic material, such as, but not limited to, aluminum or an aluminum alloy.

In some examples, the rigidity of the metal reinforcing frame 43 is relatively high, and the bottom reinforcing plate 413 may be omitted from the keyboard 40 under the condition that the rigidity of the whole keyboard 40 is ensured to meet the requirement by the metal reinforcing frame 43 and the metal connecting plate 412, that is, the bottom reinforcing plate 413 is not required to be provided, so as to be beneficial to reducing the thickness and the weight of the keyboard 40. Illustratively, the material of the metal reinforcing frame 43 may be stainless steel, so that the metal reinforcing frame 43 itself is relatively stiff.

In some implementations, fig. 14 schematically shows a partially exploded structure of the keyboard assembly 30. Fig. 15 schematically shows a partially cut-away structure of the keyboard assembly 30. Referring to fig. 14 and 15, the base member 41 further includes a backlight module 414. Along the thickness direction Z of the keyboard 40, the circuit board 411, the metal connection board 412, and the backlight module 414 are stacked. Illustratively, the metal connection plate 412 is disposed between the circuit board 411 and the backlight module 414. The backlight module 414 can be used for providing backlight for the keys 42, so that in the environment with darker light, a user can clearly observe the corresponding keys 42, the possibility of misoperation of the keys 42 is reduced, and the input accuracy and the input efficiency are improved. The light generated by the backlight module 414 can be transmitted to the external environment from the lower side of the keycap 422 through the second avoidance hole 43a of the metal reinforcing frame 43.

In some examples, the base member 41 includes a bottom stiffening plate 413. The circuit board 411, the metal connection board 412 and the backlight module 414 are disposed on a side of the bottom reinforcing plate 413 facing the keycap 422. Along the thickness direction Z of the keyboard 40, the circuit board 411, the metal connection board 412 and the backlight module 414 are disposed between the metal reinforcing frame 43 and the bottom reinforcing plate 413.

In some examples, the key cap 422 includes a pressing plate 4221 and a bezel 4222. The blocking plate 4222 can block the light generated by the backlight module 414 under the keycap 422, so as to reduce the possibility of high brightness of the light caused by the direct emergence of the light from the gap between the pressing plate 4221 and the separation strip 431, thereby reducing the possibility of glare caused by high brightness of the light.

In some implementations, fig. 16 schematically shows a partially exploded structure of the keyboard assembly 30. Referring to fig. 16, the base member 41 further includes an insulating plate 415. Along the thickness direction Z of the keyboard 40, the circuit board 411, the metal connection board 412, and the insulating board 415 are stacked. Illustratively, a metal connection plate 412 is disposed between the circuit board 411 and the insulating plate 415. Illustratively, the base member 41 includes a bottom stiffening plate 413. The circuit board 411, the metal connection board 412, and the insulating board 415 are disposed on a side of the bottom reinforcing plate 413 facing the key cap 422.

Fig. 17 schematically shows the structure of the metal reinforcing frame 43 and the connecting member 45. Fig. 18 is an enlarged view at M in fig. 17. Fig. 19 schematically shows a partially cut-away structure of the keyboard assembly 30. Referring to fig. 17, 18 and 19, the keyboard 40 further includes a connector 45. The connector 45 includes a first member 451 and a second member 452. The first member 451 is connected to the metal reinforcing frame 43. The base member 41 has a mounting hole 41a. The first member 451 is inserted into the mounting hole 41a. The first member 451 and the second member 452 are connected to each other to connect the metal reinforcing frame 43 and the base member 41. The second member 452 presses against the base member 41 to apply a compressive stress to the base member 41 toward the metal reinforcing frame 43.

For example, the connection 45 may be provided at the intersection of the transverse separator bar 431 and the longitudinal separator bar 431.

Illustratively, the first member 451 and the second member 452 may be threaded. For example, the first member 451 may be a stud. The second member 452 may be a screw. The screw has a cap. After the screw is connected with the stud, the nut may press against the base member 41 to apply a compressive stress to the base member 41 toward the metal reinforcing frame 43.

Illustratively, the first member 451 and the metal reinforcing frame 43 may be an integrally formed structure. A threaded hole is machined into the first member 451 by machining. In the case where the thickness of the metal reinforcing frame 43 itself is designed to be small, the screw holes may penetrate the metal reinforcing frame 43. A cover frame 44 may be provided at a side of the metal reinforcing frame 43 facing the key cap 422, so that the screw hole may be blocked by the cover frame 44 to enhance the aesthetic appearance.

The metal connection plate 412 includes a protrusion 412a. The protruding portion 412a is provided corresponding to the mounting hole 41a of the base member 41. At least a portion of the boss 412a may be located within the mounting hole 41 a. The convex portion 412a is connected to the connecting member 45. The metal reinforcing frame 43 is connected to the convex portion 412a on the metal connection plate 412 through the connection member 45. The protruding portion 412a of the metal connecting plate 412 can be pressed against the surface of the metal reinforcing frame 43 opposite to the keycap 422, so that the metal connecting plate 412 can provide supporting force for the metal reinforcing frame 43 through the protruding portion 412a to improve the deformation resistance of the metal reinforcing frame 43. Because the rigidity of the metal connection plate 412 is relatively high in the base member 41, the connection member 45 and the protrusion 412a are connected, so that the metal connection plate 412 is not easy to deform when the connection member 45 applies a force to the metal connection plate 412, which is beneficial to improving the connection stability between the metal reinforcement frame 43 and the base member 41.

The protruding portion 412a may be provided with a through hole. The through hole communicates with the mounting hole 41a. The first member 451 is disposed through the through hole, and the second member 452 is disposed on a side of the protrusion 412a facing away from the key cap 422.

Alternatively, fig. 20 schematically shows a partial cross-sectional structure of the keyboard assembly 30. Referring to fig. 20, the first member 451 is positioned at a side of the protrusion 412a facing the key cap 422, and the second member 452 is inserted through the through-hole of the protrusion 412a and coupled to the first member 451. The surface of the protrusion 412a facing the keycap 422 is pressed against the surface of the first member 451 facing away from the keycap 422, so that the metal connection plate 412 can provide a supporting force to the metal reinforcing frame 43 through the protrusion 412a and the first member 451, thereby improving the deformation resistance of the metal reinforcing frame 43. The metal reinforcing frame 43 can limit the protrusion 412a by the first member 451, thereby reducing the possibility of deformation of the metal connection plate 412 when the connection member 45 applies a force to the metal connection plate 412.

In other realizations, FIG. 21 schematically shows a partial cross-sectional structure of the keyboard assembly 30. Referring to fig. 21, the keyboard 40 further includes a connector 45. The connection 45 is connected to the metal reinforcing frame 43. The connecting member 45 is a hot melt member. The base member 41 has a mounting hole 41a. The connecting piece 45 is inserted into the mounting hole 41a. The connector 45 has a cap 45a. The cap 45a presses against the base member 41 to apply a compressive stress to the base member 41 toward the metal reinforcing frame 43.

In the process of connecting the metal reinforcing frame 43 and the base member 41, the connecting piece 45 on the metal reinforcing frame 43 is inserted into the mounting hole 41a on the base member 41. Then, the connection member 45 is subjected to a heat fusion process using a heat fusion process to deform the connection member 45. After the connection 45 is cooled and solidified, a stable connection between the metal reinforcing frame 43 and the base assembly is achieved.

Illustratively, the material of the connector 45 is plastic. For example, the connection 45 may be connected to the metal reinforcing frame 43 using an injection molding process.

Illustratively, the metal connection plate 412 includes a protrusion 412a. The protruding portion 412a is provided corresponding to the mounting hole 41a of the base member 41.
