As shown in fig. 2, when the face cover 11 is engaged with the bottom case 15, the panel 111 is displaced downward by pressing any position of the panel 111, and the switch member 19 is triggered. For example, when the substantially central position of the panel 111 is pressed, the first joint portion moves downward with respect to the second joint portion as a whole, and the panel 111 presses the switch member 19 to be activated. When the edge position of the panel 111 is pressed, the panel 111 rotates with the engagement structure on the side opposite to the pressing position as a fulcrum, the first engagement portion on the side close to the pressing moves downward with respect to the second engagement portion, and the panel 111 presses the switch member 19 to be triggered.

The elastic buffer part can be a silica gel sleeve in the embodiment, and the second waterproof elastic part can be an elastic sealing ring.

Specifically, as shown in fig. 13 and 14, the signal transmitter of the present embodiment includes a face cover 11, a control board 13, a bottom case 15, a lower cover 12, and an elastic buffer 27 and a second waterproof elastic member 14. The cover 11 includes a cover panel 111 and a cover sidewall 113, the bottom casing 15 includes a bottom casing bottom plate 151, a bottom casing sidewall 153 and a bottom casing inner wall 152, and the bottom casing sidewall 153 is located at the periphery of the bottom casing inner wall 152. The elastic buffer 27 is of a sealing cover structure, the second waterproof elastic element 14 is of a sealing ring structure, and the elastic buffer 27 is matched with the surface cover 11 and the bottom shell 15 and the second waterproof elastic element 14 is matched with the lower cover 12 and the bottom shell 15 to form a sealing cavity. The control panel 13 is located in the sealed cavity and fixed on the bottom shell 15 in a manner similar to that in fig. 1 and 2, a power supply installation position is arranged on one side of the control panel 13 far away from the face cover 11 and used for containing a power supply 18, and the power supply 18 is used for supplying power to the control panel 13. The control board 13 is connected with a switch part 19.

The elastic buffer 27 includes an elastic cover 271 and a sealing outer edge 273 extending outward along the edge of the elastic cover 271, the elastic buffer 27 is sleeved on the inner wall 152 of the bottom case, the front cover panel 111 has a first protrusion 115, and in a state that the front cover 11 and the bottom case 15 are engaged, the sealing outer edge 273 is pressed against the bottom case base 151 by the first protrusion 115 to form a sealing contact. Similarly to the foregoing, in a state where the lower cover 12 is engaged with the bottom case 15, the lower cover 12 is brought into sealing contact with the bottom case 15 by the second waterproof elastic member 14. At this time, the elastic buffer 27, the bottom case 15, the second waterproof elastic member 14, and the lower cover 12 together form a sealed cavity. The control panel 13, the switch part 19 and the power supply 18 are all positioned in the sealed cavity to achieve the aim of water resistance.

As shown in fig. 14, the control board 13 is located at a position substantially at the center of the signal transmitter, the switch member 19 is located at a position substantially at the center of the control board 13, and at least a partial region of the elastic cover 271 is of an elastic structure, for example, a connection section between the sealing cover and the sealing outer edge is made of an elastic material, or a portion of the sealing cover corresponding to the switch member 19 is made of an elastic material. When the panel 111 is pressed, the panel 111 displaces downwards, the elastic cover 271 displaces downwards correspondingly, the panel 111 presses the switch member 19 through the elastic cover 271, the switch member 19 is triggered, the key command generating circuit in the control board is switched on and generates a corresponding key command, and the signal generator further completes the transmission of the wireless control signal based on the key command. After the external force is removed, the front cover panel 111 is restored to the initial state under the combined action of the elastic restoring force of the elastic cover 271 and the upward pushing force generated by the reset of the switch part 19, the switch part 19 is reset, and the key command generating circuit in the control panel is turned off. Similarly, by the structure that the face cover 11 is engaged with the bottom case 15, any position of the face cover panel 111 is pressed, and the face cover panel 111 is displaced downward, thereby triggering the switch member 19.

Similarly to the foregoing, the cover panel 111 may be made of a rigid material, or may be made of an elastic material. When the face cover panel 111 is made of an elastic material, the face cover panel 111 is pressed, the face cover panel 111 is elastically deformed by an external force, the elastic cover body 271 is displaced or deformed downward, and the face cover panel 111 presses the switch member 19 through the elastic cover body 271, thereby triggering the switch member 19. After the external force is removed, under the combined action of the elastic restoring force of the surface cover panel 111 and the elastic cover body 271 and the upward pushing force generated by the reset of the switch component 19, the surface cover panel 111 is restored to the initial state, the switch component 19 is reset, and the key command generating circuit in the control board is disconnected.

In some embodiments, the cover panel has a push arm (not shown) that is pressed to displace the cover panel downward, and the push arm presses the switch member via the sealing cover body to trigger the switch member.

In some embodiments, the sealing cap is an elastomeric cap constructed of an elastomeric material, such as a silicone cap or a rubber cap constructed of silicone or rubber. The sealing outer edge is an elastic outer edge made of an elastic material, for example, a silicone outer edge or a rubber outer edge made of silicone or rubber. Further, the sealing cover may also be a structure including an elastic cover and a non-elastic cover, for example, a silicone cover or a structure formed by combining a rubber cover and a plastic cover. The sealing outer edge can also be a structure comprising an elastic outer edge and a non-elastic outer edge, for example, a structure formed by combining a silica gel outer edge or a rubber outer edge with a plastic outer edge. The specific design of the closure body may vary, as long as sealing contact and normal triggering of the switch member is achieved. It should be understood that the seal outer edge corresponds to the seal ring structure described above. The various abutment means for sealing with the sealing ring can be similarly applied to the sealing outer edge structure, i.e. sealing contact can be achieved.

Specifically, the elastic buffer 27 may be in other sealing contact systems than the sealing contact system shown in fig. 14. For example, in some embodiments, the cover panel is provided with a protrusion, and the base panel is provided with a channel structure formed by two protrusions (where the protrusions may be separate protrusions formed on the panel, or may be a sidewall structure including, for example, a second base sidewall), and the sealing rim is disposed in the channel structure, and the protrusion of the cover panel presses against the sealing rim to form a sealing contact. In some embodiments, the face cover panel is provided with a protrusion, the surface of the bottom shell panel is provided with a groove, the elastic buffer is arranged in the groove, and the protrusion of the face cover panel is pressed against the sealing outer edge to form sealing contact. Similarly, the structures of the top cover panel and the bottom cover panel for forming the seal can be interchanged, and the effects are the same or similar, and are not described in detail herein.

In some embodiments, the face cover panel is provided with a protrusion, the bottom plate is provided with a bottom plate protrusion, the elastic outer edge is sleeved on the periphery of the bottom plate protrusion, and the protrusion of the face cover panel presses the elastic outer edge against the bottom plate to form a sealing contact in a state that the face cover is clamped with the bottom plate. Similarly, in some embodiments, the bottom chassis base is provided with a protrusion, the face cover panel is provided with a face cover protrusion, and the elastic outer edge structure is adaptively adjusted so that the elastic outer edge sleeve is sleeved on the periphery of the face cover protrusion, and in a state that the face cover is clamped with the bottom chassis, the protrusion of the bottom chassis base presses the elastic outer edge against the face cover panel to form a sealing contact.

In some embodiments, the face cover panel is provided with first protruding portions, the bottom case bottom plate is provided with two first protruding portions, the first protruding portions arranged on the face cover panel are arranged opposite to one of the first protruding portions arranged on the bottom case bottom plate, the elastic outer edge is sleeved on the periphery of the other first protruding portion of the bottom case bottom plate and is fixed, and the elastic outer edge is abutted against the end faces of the two first protruding portions arranged opposite to each other to form sealing contact. Similarly, the two first protruding portions of the bottom chassis may be of mutually independent structures, or the two first protruding portions of the bottom chassis may together form a different part of a structure, for example, form a stepped structure. Similarly, the structural arrangements on the top cover and bottom cover may be interchanged.

The elastic buffer and the bottom shell 15 surround to form a sealed inner cavity, and the control panel 13, the switch component 19 and the power supply 18 are all located in the inner cavity, so that the waterproof purpose is achieved.

Fig. 15 and 16 are an exploded view and a sectional structure diagram of the signal transmitter of the present embodiment, respectively. The signal transmitter adopts the elastic buffer piece for water and moisture prevention, and the middle cover plate is provided with a middle cover hole. Specifically, as shown in fig. 15 and 16, the signal transmitter includes a middle cover 16, a control board 13, a bottom cover 15, an elastic buffer 27, and a face cover 11. The middle cover 16 includes a middle cover plate 161 and a middle cover sidewall 163, and the middle cover plate 161 is provided with a middle cover opening 168. The elastic buffer 27 is an elastic cover, such as a silicone cover or a rubber cover, and includes an elastic cover body 271 and an elastic outer edge 273 extending outward along an edge of the elastic cover body 271. The middle cover 161 is provided with a second protrusion 162, and the second protrusion 162 presses the elastic outer edge 273 against the bottom plate 151 of the bottom case when the middle cover 16 is engaged with the bottom case 15. At this time, the elastic cover and the bottom case surround to form a sealed inner cavity, and the control board 13, the switch component 19 and the power supply 18 are all located in the inner cavity, so as to achieve the purpose of water resistance.

The bottom plate 151 of the bottom case is provided with a second protrusion 1511, and the elastic outer edge 273 is sleeved on the periphery of the second protrusion 1511 to fix the elastic buffer 27 and prevent the elastic buffer 27 from moving. The inner side of the second protrusion 1511 further has a stopper 1512, and the edge of the control board 13 is fixed on the bottom chassis 151 by engaging with the stopper 1512. In addition, the control board 13 may be fixed to the bottom chassis 151 by glue or rivets. It should be understood that such a protrusion that performs both the elastomeric bumper retention and the control panel securing functions may also be applied to other embodiments of the present invention. The sealing and pressing method shown in fig. 16 is merely an example, and other pressing and sealing methods may be used. Specifically, as mentioned above, the elastic outer edge is equivalent to the elastic ring structure, and the sealing contact can be realized by adopting the same pressing manner as the elastic ring structure. Since the related embodiments have been described in detail in the foregoing, detailed description is omitted here.

The elastic cover 271 further includes an elastic panel 2712 and elastic side walls 2711 (unnumbered in fig. 16, see the numbering in fig. 18), the elastic panel 2712 having bumper protrusions 279. The bumper protrusion 279 extends into the middle cap opening 168, the push arm 112 also extends into the middle cap opening 168, the push arm 112 abuts against the bumper protrusion 279, and the bumper protrusion 279 is not in contact with the switch member 19 at a distance. In some embodiments, the bumper protrusion 279 may also be in contact with the switch member 19. The control board 13 is located at a substantially central position of the signal transmitter, and the switch part 19 is located at a substantially central position of the control board 13.

Similarly, by the structure that the face cover 11 is engaged with the bottom case 15, any position of the face cover panel 111 is pressed, and the face cover panel 111 is displaced downward, thereby triggering the switch member 19.

In fact, the elastic bulge is not necessary, and the position relationship between the elastic bulge and the pushing arm and the hole of the middle cover can be flexibly designed. For example, in some embodiments, the resilient tab extends through the middle cap opening, in which case the push arm can be selectively retained or omitted. In some embodiments, the resilient projection is located below the middle cap opening through which the push arm passes. In some embodiments, the resilient panel is a generally planar structure with the push arm 112 passing through the middle cap aperture 168. However, regardless of the existence and specific arrangement of the elastic protrusions, the elastic cover body is in contact with the push arm, the push arm triggers the switch component through the elastic cover body under the action of external force, and the elastic cover body helps the cover panel to return to the initial state under the action of elastic restoring force after the external force is removed.

Although the elastic buffer member shown in fig. 15 and 16 is a silicone cap or a rubber cap, in fact, as mentioned above, further, the elastic buffer member is a sealing cap structure including a silicone cap or a rubber cap, or a sealing cap structure including an elastic cap body and an elastic outer edge, for example, the elastic buffer member may be a sealing cap in which the elastic cap body and the elastic outer edge are combined with a plastic structure.

The combination and implementation of other components, such as the engagement between the middle cover and the bottom case and the engagement between the face cover and the bottom case, are the same as those in the previous embodiment, and therefore, they are directly incorporated herein, and are not described herein again.

The face lid panel of this embodiment directly supports to press the switch part at a distance from the elasticity lid, compares in the situation of separating the well lid, and is more nimble in the operation, and because the face lid does not undertake waterproof relevant function, the design of material and structure is more nimble, and convenience of customers carries out reprocessing according to own hobby.

The side of the control panel 13 away from the middle cover 16 is provided with a power supply mounting position for accommodating a power supply 18. The control board 13 is connected with a switch part 19.

The elastic buffer 27 includes an elastic cover 271 and a sealing outer edge 273 extending outwards along the edge of the elastic cover 271, the bottom chassis 151 has a protrusion 1511 thereon, the elastic buffer 27 is sleeved on the protrusion 1511, the middle cover 161 has a protrusion 165, and in a state that the middle cover 16 and the bottom chassis 15 are engaged, the protrusion 165 presses the sealing outer edge 273 against the bottom chassis 151 to form a sealing contact. Similarly to the foregoing, in a state where the lower cover 12 is engaged with the bottom case 15, the lower cover 12 is brought into sealing contact with the bottom case 15 by the second waterproof elastic member 14. At this time, the elastic buffer 27, the bottom case 15, the second waterproof elastic member 14, and the lower cover 12 together form a sealed cavity. The control panel 13, the switch part 19 and the power supply 18 are all located in the sealed cavity to achieve the waterproof purpose.

EXAMPLE ten

Referring to fig. 19 and 20, a signal transmitter according to a tenth embodiment of the present invention is different from the signal transmitter according to the previous embodiments in that the signal transmitter further includes an inner cover 26, the middle cover 16 is provided with a middle cover through hole 164, the buffering elastic member 27 is provided with an elastic member through hole 278, and the inner cover 26 is matched with the elastic member through hole 278 through the middle cover through hole 164 to form a second accommodating cavity. The inner cover 26 comprises an inner cover side wall 263 and an inner cover plate 261, an inner cover hook 265 is arranged on the inner cover side wall 263, and the inner cover hook 265 is matched with a through hole of the middle cover 16 to realize the clamping of the inner cover 26 and the middle cover 16.

The elastic member through hole 278 has a through hole outer edge, and the inner cover side wall 263 presses the through hole outer edge against the control plate, so that a seal is formed between the buffering elastic member 27 and the control plate 13. The second accommodating cavity is internally provided with a power supply mounting position.

Fig. 19 and 20 are an exploded view and a sectional structure diagram of the signal transmitter of the present embodiment, respectively. The signal transmitter includes a middle cover 16, a control board 13, a bottom cover 15, an elastic buffer 27, a face cover 11, and an inner cover 26. The middle cover 16 includes a middle cover plate 161 and a middle cover sidewall 163, and the middle cover plate 161 is provided with a third middle cover through hole 164 and a second middle cover through hole 166. The inner lid 26 is disposed at the third middle lid through hole 164, and is engaged with the middle lid plate 161. The elastic buffer 27 is an elastic cover, and includes an elastic cover body 271, an elastic outer edge 273 extending outward along the edge of the elastic cover body 271, and an elastic member through hole 278 arranged in the elastic outer edge, the position and size of the elastic member through hole 278 correspond to those of the inner cover 26, the power supply installation position on the control board 13 is located in the elastic member through hole 278, and the power supply 18 can be exposed by removing the inner cover 26, so that the power supply can be conveniently dismounted or replaced.

As shown in fig. 20, the control board 13 is located at the approximate center of the signal transmitter, the switch component 19 and the power source 18 are disposed on the control board 13, the middle cover 16 and the inner cover 26 press against the elastic outer edge 273, the elastic buffer 27, the inner cover 26 and the bottom case 15 surround to form a sealed inner cavity, and the control board 13, the switch component 19 and the power source 18 are disposed in the inner cavity. In addition, the inner cover 26 presses the elastic outer edge 274 around the elastic member through hole 278 against the control board 13 in a state of being engaged with the middle cover plate 161, the inner cover 26 is in sealing contact with the elastic buffer member 27, and the inner cover 26, the elastic outer edge 274 and the control board 13 form a sealed first accommodating cavity for accommodating the power supply 18. The switch member 19 is disposed in a second accommodation chamber other than the first accommodation chamber of the inner chamber a1, at a position corresponding to the elastic cover body 271. It can be seen that the switch member 19 is not located at the approximate center of the control board 13, and this design helps to further reduce the size of the signal transmitter, thereby realizing miniaturization of the signal transmitter. In some embodiments, the switch member 19 may still be disposed at a substantially central location of the control board 13 to facilitate control of the signal emitter.

Further, as shown in fig. 20, the inner lid 26 includes an inner lid plate 261 and an inner lid side wall 263, the inner lid side wall 263 has an inner lid hook thereon, and the inner lid 26 and the middle lid 16 are engaged by the inner lid hook. Of course, the inner lid 26 and the middle lid 16 may be engaged by other structures, for example, in some embodiments, the inner lid side wall 263 has a groove through which the inner lid 26 and the middle lid 16 are engaged.

Other combinations and embodiments of the components, such as the engaging manner of the middle cover and the face cover with the bottom case, the specific structure of the elastic cover, the relationship among the elastic cover, the pushing arm and the switch component, the positional relationship among the elastic protrusion and the middle cover opening, and the manner of the middle cover and the bottom case forming the sealing abutment with the elastic cover, are the same as those of the previous embodiments, and therefore, they can be directly cited here, and are not repeated herein.

This embodiment makes things convenient for the dismouting of power through increasing the inner cup.
