As shown in fig. 1, in the present embodiment, the calculator proposed by the present disclosure mainly includes two cases, a key assembly, a voice assembly, a power supply assembly, and a seal ring 150. Referring to fig. 2 through 6 in combination, fig. 2 representatively illustrates an enlarged view of portion a of fig. 1; representatively, an enlarged view of portion B of fig. 1 is shown in fig. 3; a cross-sectional view of the speech assembly is representatively illustrated in fig. 4; a cross-sectional view of the power supply assembly is representatively illustrated in fig. 5; a cross-sectional view of display screen 510 is representatively illustrated in fig. 6. The structure, connection mode and functional relationship of the main components of the calculator proposed by the present disclosure are explained in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, two housings of the calculator are defined below as a first housing 110 and a second housing 120, respectively, for ease of understanding and description. Specifically, the first casing 110 has a first bezel 111, and the second casing 120 has a second bezel 121. The first casing 110 and the second casing 120 are respectively formed into an integral casing of the calculator by the buckling and butt joint of the first frame 111 and the second frame 121, and the inner cavity 130 can be formed after the buckling and butt joint of the first casing 110 and the second casing 120. The sealing ring 150 is disposed between the first casing 110 and the second casing 120, specifically, between the first frame 111 and the second frame 121, and the sealing ring 150 can form a seal between the first frame 111 and the second frame 121, so as to achieve a sealing effect after the first casing 110 and the second casing 120 are fastened and butted. Through the design, the calculator provided by the disclosure can avoid the defects that mistaken pressing and the wrong pressing cannot be fed back immediately. By providing a waterproof structure such as the sealing ring 150, the present disclosure can better protect electronic components inside the calculator, and can be used in areas and workplaces with high humidity and moisture.

Further, due to the design that the gasket 150 is interposed between the first frame 111 and the second frame 121, in the present embodiment, the gasket 150 has substantially the same contour shape as the first frame 111 and the second frame 121. For example, when the first frame 111 and the second frame 121 are annular closed structures, the sealing ring 150 may preferably adopt an annular closed structure.

Further, in the present embodiment, the material of the gasket 150 may preferably be a rubber material, such as soft rubber, based on the design that the gasket 150 is disposed between the first frame 111 and the second frame 121, and is not limited in the present embodiment.

As shown in fig. 2, in the present embodiment, the first frame 111 may preferably be formed with a sealing groove, which is defined as a first sealing groove 112 for distinguishing from sealing grooves formed in other structures. Accordingly, the sealing ring 150 may preferably have a sealing limb defined as a first sealing limb 151 for distinguishing it from sealing limbs of other sealing structures. Wherein the first sealing limb 151 is correspondingly disposed within the first sealing groove 112. That is, when the seal ring 150 is interposed between the first frame 111 and the second frame 121, the first seal leg 151 of the seal ring 150 is correspondingly engaged in the first seal groove 112 of the first frame 111. Accordingly, the sealing effect between the first housing 110 and the second housing 120 can be improved by the design of the first sealing groove 112 and the first sealing limb 151.

In other embodiments, the first seal groove 112 may be formed only in the second frame 121, or the first seal groove 112 may be formed in each of the first frame 111 and the second frame 121 at the same time. The number of the first seal grooves 112 opened in either one of the first frame 111 and the second frame 121 is not exclusive. That is, the first frame 111 may or may not be provided with at least one first sealing groove 112, and the second frame 121 may or may not be provided with at least one first sealing groove 112, that is, at least one of the first frame 111 and the second frame 121 may be provided with the first sealing groove 112. Accordingly, the sealing ring 150 may preferably have first sealing limbs 151 corresponding to the number and positions of the first sealing grooves 112, one to one, respectively.

Further, based on the design of the first sealing groove 112 and the first sealing limb 151, in the present embodiment, when the material of the sealing ring 150 is preferably a rubber-like material, the width of the first sealing limb 151 may be designed to be slightly larger than the groove width of the first sealing groove 112, that is, when the first sealing limb 151 is snapped into the first sealing groove 112, the first sealing limb 151 and the first sealing groove 112 form an interference fit, so as to further improve the sealing effect between the first casing 110 and the second casing 120. In other embodiments, the design of the interference fit between the first sealing leg 151 and the first sealing groove 112 may be selected regardless of the material of the sealing ring 150, and is not limited to this embodiment.

Further, based on the design of the first sealing groove 112 and the first sealing limb 151, in the present embodiment, the two frames respectively have abutting end surfaces, and the two frames respectively abut with the respective abutting end surfaces. On this basis, the abutting end surface of the first frame 111 may preferably be provided with a first sealing groove 112, and the abutting end surface of the second frame 121 may preferably be designed as a plane. In other embodiments, the design of the abutting end surfaces of the first frame 111 and the second frame 121 may refer to the corresponding design of the first sealing groove 112 and the first sealing limb 151, respectively, and will not be described herein again.

Further, as shown in fig. 2, based on the design that the first sealing groove 112 is opened on the first frame 111 and the first sealing groove 112 is not opened on the second frame 121, in the present embodiment, the sealing ring 150 has one first sealing limb 151, so that the cross-sectional shape of the sealing ring 150 may preferably be substantially "L" shaped, and the groove shape of the first sealing groove 112 may preferably be substantially "U" shaped. In other embodiments, the cross-sectional shape of the seal ring 150 may be cross-shaped, T-shaped, M-shaped, H-shaped, etc., and the groove shape of the first seal groove 112 may be other corresponding shapes, all without being limited to this embodiment.

In the present embodiment, the first casing 110 and the second casing 120 may be preferably connected to the gasket 150 by a connector, based on the design that the gasket 150 is interposed between the first casing 110 (the first frame 111) and the second casing 120 (the second frame 121). For example, after the first housing 110 and the second housing 120 are fastened, the connection function can be achieved by using a connector such as a screw. Accordingly, through the design of the connection member, the seal ring 150 can be prevented from moving after the first casing 110 and the second casing 120 are butted, and meanwhile, the seal ring 150 can be further compressed by screwing the screw, so that the sealing effect is further improved.

As shown in fig. 1, in the present embodiment, the first housing 110 has a plurality of key holes 140 opened therein. The key assembly mainly includes a circuit board 210 and a plurality of keys 220. The circuit board 210 is disposed in the inner cavity 130 formed by the first casing 110 and the second casing 120, the plurality of keys 220 are disposed in the plurality of key holes 140 formed in the first casing 110, and a portion of each key 220 is exposed out of the corresponding key hole 140. Keys 220 adjustably make electrical contact with circuit board 210 using portions thereof located in interior 130. That is, when the portion of the key 220 exposed out of the corresponding key hole 140 is pressed by the operator, the key 220 moves towards the inner cavity 130, and the portion of the key 220 located in the inner cavity 130 is electrically connected to the circuit contact on the circuit board 210 corresponding to the position of the key 220, thereby implementing the input function of the key 220. In addition, an elastic recovery mechanism is further disposed between the key 220 and the circuit board 210, so that the key 220 pressed by the pressing can be recovered to the initial position by the elastic recovery force provided by the elastic recovery mechanism after the pressing external force disappears.

As shown in fig. 1 and 3, in the present embodiment, the key assembly may also preferably include a first gasket 230. Specifically, the first gasket 230 is disposed in the inner cavity 130 and between the circuit board 210 and the key 220. The inner wall of the first housing 110 is protruded with a protrusion 113 toward the inner cavity 130, and the edge of the first sealing gasket 230 is disposed between the circuit board 210 and the protrusion 113. Accordingly, the first gasket 230 separates the circuit board 210 from the key 220, thereby forming a seal between the circuit board 210 and the first housing 110 in which the key 220 is disposed. Specifically, by the design of the first gasket 230, water can be isolated outside the first gasket 230, and cannot enter electronic components such as the circuit board 210 inside the calculator, and the normal operation of the keys 220 of the calculator can be ensured, and finally, the waterproof and sealing effects can be achieved. The accumulated water outside the first gasket 230 can flow out through the gap between the key 220 and the keyhole 140, and it is ensured that no more water is accumulated in the key 220. In addition, the first gasket 230 comprises a conductive material, and the key 220 is adjustably electrically contacted to the circuit board 210 through the first gasket 230. That is, when the portion of the key 220 exposed out of the corresponding key hole 140 is pressed by the operator, the key 220 moves towards the inner cavity 130, the portion of the key 220 located in the inner cavity 130 contacts with the first gasket 230 and presses the portion of the first gasket 230 to move towards the circuit board 210, until the first gasket 230 contacts with the circuit contact on the circuit board 210 corresponding to the position of the key 220, so that the key 220 and the circuit board 210 are electrically connected through the first gasket 230, and the input function of the key 220 is realized.

In other embodiments, the number and the arrangement position of the protruding ribs 113 may also adopt other designs. For example, the protruding edge 113 may be only disposed on the circuit board 210, or the protruding edges 113 may be disposed on the inner wall of the first casing 110 and the circuit board 210 at the same time, and the number of the protruding edges 113 disposed at the two positions is at least one. Correspondingly, the edge of the first sealing gasket 230 may also be disposed between the inner wall of the housing and the protruding edge 113 disposed on the circuit board 210, or may also be disposed between the protruding edge 113 disposed on the housing and the protruding edge 113 disposed on the circuit board 210, which is not limited by the present embodiment.

Further, as shown in fig. 3, based on the design of the first sealing gasket 230 and the convex edge 113, in the present embodiment, the convex edge 113 may be preferably provided with a sealing groove, and the sealing ring 150 has at least one sealing limb, and the sealing limbs are disposed in the sealing groove in a one-to-one correspondence manner.

Further, as shown in fig. 3, based on the design of the first sealing gasket 230 and the protruding edge 113, in the present embodiment, a sealing groove may be preferably formed on the protruding edge 113, and the sealing groove is defined as the second sealing groove 114 in order to be distinguished from sealing grooves formed on other structures. Accordingly, the first gasket 230 may preferably have a sealing limb defined as the second sealing limb 231 to distinguish it from sealing limbs of other sealing structures. Wherein the second sealing limb 231 is correspondingly disposed within the second sealing slot 114. That is, when the second gasket 440 is interposed between the flange 113 and the circuit board 210, the second sealing leg 231 of the first gasket 230 is correspondingly snapped into the second sealing groove 114 of the flange 113. Accordingly, by the design of the second sealing groove 114 and the second sealing limb 231, the sealing effect of the first casing 110 at the position where the keyhole 140 is formed, that is, the sealing effect of the key assembly, can be improved.

In other embodiments, the number of the second sealing grooves 114 formed in the flange 113 is not the only number. That is, the ridge 113 may or may not be provided with at least one second sealing groove 114. Accordingly, the first sealing gasket 230 may preferably have second sealing limbs 231 corresponding to the number and positions of the second sealing grooves 114, respectively, one to one.

Further, based on the design of the second sealing groove 114 and the second sealing limb 231, in this embodiment, when the material of the first sealing gasket 230 is preferably a rubber-like material, the width of the second sealing limb 231 may be designed to be slightly larger than the groove width of the second sealing groove 114, that is, when the second sealing limb 231 is clamped into the second sealing groove 114, the second sealing limb 231 and the second sealing groove 114 form an interference fit, so as to further improve the sealing effect of the first housing 110 where the keyhole 140 is formed, that is, further improve the sealing effect of the key assembly. In other embodiments, the design of the interference fit between the second sealing leg 231 and the second sealing groove 114 can be selected regardless of the material of the first sealing gasket 230, and is not limited to this embodiment.

Further, as shown in fig. 3, based on the design that the convex edge 113 of the first housing 110 is provided with the second sealing groove 114, in the present embodiment, the edge of the first sealing gasket 230 has the second sealing limb 231, so that the cross-sectional shape of the edge of the first sealing gasket 230 may be substantially "T" or "L", and the groove shape of the second sealing groove 114 may be substantially "U". In other embodiments, the cross-sectional shape of the edge of the first seal gasket 230 may be a cross shape, an M shape, an H shape, etc., and the groove shape of the second seal groove 114 may be other corresponding shapes, all without being limited to this embodiment.

Further, based on the design of the first gasket 230, in the present embodiment, the material of the first gasket 230 may preferably be a rubber material containing a conductive material, such as a conductive soft rubber. In addition, when the first gasket 230 is made of a rubber material, a plurality of elastic contact structures, such as arch structures, corresponding to the plurality of keys 220, may be preferably formed on the first gasket 230 by using the elastic characteristics of the rubber material. For example, the elastic contact structure can accumulate elastic potential energy when being touched and pressed by the key 220, and when the touch pressure applied to the key 220 by the operator is weakened or disappeared, the elastic contact structure releases the elastic restoring force to restore the key 220 to the original position. That is, in the present embodiment, the first gasket 230 can also provide similar functions of the elastic restoring mechanism, without providing an additional elastic restoring mechanism.

Further, based on the design that the key assembly includes the circuit board 210, in the present embodiment, the circuit board 210 may preferably include the PCB circuit board 210. In other embodiments, the circuit board 210 may also include other circuit elements, and is not limited to the present embodiment.

In the present embodiment, the first housing 110, the circuit board 210, and the first gasket 230 may be preferably connected by a connector based on the design that the first gasket 230 is disposed between the first housing 110 and the circuit board 210. For example, the above-described connecting function may be achieved using a connecting member such as a screw. Accordingly, through the design of the connecting member, the first gasket 230 can be prevented from moving, and the first gasket 230 can be further compressed by screwing the screw, so that the sealing effect is further improved.

As shown in fig. 4, in this embodiment, a voice assembly is disposed in the interior chamber 130 and can be used to emit voice information. On this basis, the voice module may preferably include a speaker 310 and a waterproof membrane 320. Specifically, a cavity 160 is formed on an inner wall of the housing (the housing is not particularly limited to one of the first housing 110 and the second housing 120), and the speaker 310 is disposed in the cavity 160. The waterproof membrane 320 is disposed on the wall of the cavity 160 and between the housing (wall) and the horn 310. Accordingly, the sealing effect of the voice module can be improved by the design of the waterproof film 320.

Further, based on the design of the voice assembly including the speaker 310, in the present embodiment, the speaker 310 may be preferably selected as the waterproof speaker 310. Accordingly, the sealing effect of the voice assembly can be further improved by the type selection of the waterproof loudspeaker 310. In other embodiments, the speaker 310 may also employ other types of voice devices, and is not limited to the present embodiment.

Further, based on the design that the voice module includes the waterproof film 320, in the present embodiment, the material of the waterproof film 320 may preferably be waterproof soft glue. In other embodiments, the material of the waterproof film 320 may also include other types of waterproof materials, and is not limited to the embodiment.

Specifically, with the above-described waterproof sealing design for the voice module, that is, with the double water-repellent characteristics of the waterproof speaker 310 and the waterproof film 320, it is structurally possible to prevent external moisture from entering the inside of the calculator through the open structure of the housing, such as the sound outlet, corresponding to the speaker 310. Meanwhile, the waterproof soft glue is coated on the inner wall of the groove hole 160, so that the periphery of the loudspeaker 310 is adhered and adhered to the inner wall of the groove hole 160, the sealing and waterproof effects are further provided, and meanwhile, the soft glue keeps a soft glue state due to the use of the soft glue, and the sound production effect of the loudspeaker 310 cannot be influenced. In this embodiment, the waterproof film 320 may be formed by applying a waterproof glue between the horn 310 and the cavity 160. Specifically, the waterproof glue may be coated on the surface of the horn 310 contacting the groove 160, or may be coated on the groove wall of the groove 160, which is not limited to this embodiment.

As shown in fig. 5, in the present embodiment, the power supply unit is disposed in the inner cavity 130 and is electrically connectable to the key unit and the voice unit, respectively, to supply power to the key unit and the voice unit. In addition, the power supply component may also be electrically connected to other electrical appliances of the calculator to supply power to the electrical appliances, which is not described herein. Based thereon, the power supply assembly may preferably include a battery compartment 410, a battery compartment cover 420, and a second gasket 440. Specifically, the battery compartment 410 is disposed on an outer wall of the housing (the housing is not specifically referred to as one of the first housing 110 and the second housing 120), and the battery compartment 410 is used for accommodating the battery 430. The battery compartment cover 420 can be openably and closably fastened at the compartment opening of the battery compartment 410. The second gasket 440 is disposed on the side of the battery compartment cover 420 facing the compartment opening. The second gasket 440 can form a seal between the battery compartment cover 420 and the compartment opening when the battery compartment cover 420 is fastened to the battery compartment 410. Accordingly, the second gasket 440 can improve the sealing effect between the battery case 410 and the battery case cover 420, that is, the sealing effect of the power module. Specifically, the second gasket 440 can isolate the battery compartment 410 and the battery 430 disposed in the battery compartment 410 from the outside, thereby preventing the occurrence of a short circuit caused by moisture entering the battery compartment 410.

Further, as shown in fig. 5, based on the design that the second sealing gasket 440 is disposed between the battery compartment 410 and the battery compartment cover 420, in this embodiment, a sealing groove may be preferably formed at the compartment opening of the outer wall of the casing, which is located at the battery compartment 410, and the sealing groove is defined as a third sealing groove in order to be distinguished from sealing grooves formed in other structures. Accordingly, the second gasket 440 may preferably have a sealing limb defined as a third sealing limb 441 for purposes of distinguishing it from sealing limbs of other sealing structures. Wherein the third sealing limb 441 is correspondingly disposed within the third sealing groove. That is, when the second gasket 440 is interposed between the battery case cover 420 and the case, the third sealing leg 441 of the second gasket 440 is correspondingly caught in the third sealing groove. Accordingly, the third seal groove and the third seal leg 441 are designed to further improve the sealing effect between the battery case 410 and the battery case cover 420, that is, the sealing effect of the power supply module.

In other embodiments, the third sealing groove may be formed only in the bin opening of the outer wall of the casing at the battery bin 410, or the third sealing groove may be formed in the battery bin cover 420 and the casing at the same time.
