[0165] The specific embodiments are described in detail below.

[0166] Embodiment one

[0167] The signal transmitter provided by the embodiment one of the present application has the structure as shown in Figure 1 and Figure 2 The signal transmitter comprises a face cover 11, a control board 13 and a bottom shell 15. The face cover 11 and the bottom shell 15 cooperatively form a containing cavity. The control board 13 is located in the containing cavity, and the control board 13 is connected with a switch component 19. Under the action of external force, the face cover 11 can move not more than a set distance towards the bottom shell 15 and trigger the switch component, and the control board 13 sends a control signal after the switch component 19 is triggered.

[0168] The face cover 11 comprises a face cover side wall 113 and a face plate 111. The switch component 19 is located between the face plate 111 and the control board 13 and is arranged at the middle part of the control board 13. Pressing any position of the face plate 111 can make the middle part of the face plate 111 abut against and trigger the switch component 19. After the face cover 11 and the bottom shell 15 are buckled, the middle part of the face plate is pressed, and the face cover 11 can move towards the bottom shell 15 as a whole, so that the face plate abuts against and triggers the switch component. The position of the face plate deviating from the center is pressed, and the side of the face plate pressed can make pivotal movement relative to the side far away from the pressed position, so that the face plate abuts against and triggers the switch component.

[0169] The bottom shell 15 comprises a bottom shell side wall 153 and a bottom plate 151. One of the bottom shell side wall 153 and the face cover side wall 113 is provided with a first clamping hook, and the other is provided with a first clamping groove matched with the shape of the first clamping hook. The height of the first clamping hook is less than the height of the first clamping groove. After the first clamping hook and the first clamping groove are clamped, the first clamping hook can move not more than a set distance in the first clamping groove.

[0170] The side of the control board 13 far away from the bottom shell 15 is provided with a power supply mounting position for containing a power supply 18. The switch component 19 and the power supply mounting position are arranged on the same side of the control board 13.

[0171] The signal transmitter provided by the embodiment can be relatively moved by a small distance when the surface cover is pressed, the switch component is pressed and triggered by the movement of the surface cover, and the surface cover can return to the original position after the external force disappears. The trigger of the touch switch can be realized by the simple structure, the material of the surface cover does not need to have the elastic deformation ability to trigger the switch component, and the signal transmitter module with complete functions is formed based on the surface cover, the bottom shell, the control panel and the switch component. The signal transmission operation can be independently realized under the action of the external force, the overall structure is simple and small, the operation is convenient, the disassembly and assembly are easy, and the internal parts can be easily replaced or maintained by the user. The switch component can be triggered by pressing any position of the surface cover panel, and the user does not need to pay special attention to the pressing position, so that the user can use conveniently.

[0172] The signal transmitter provided by the embodiment is Figure 1 and Figure 2 The signal transmitter without the sealing ring is the same as that in Embodiment Two except the first waterproof elastic member and the associated structure, and the possible implementation modes of the related structures are described in Embodiment Two.

[0173] Embodiment Two

[0174] The signal transmitter provided by Embodiment Two is Figure 1 and Figure 2 The difference between the signal transmitter provided by Embodiment Two and that provided by Embodiment One is that the first waterproof elastic member 17 is arranged between the surface cover 11 and the bottom shell 15, so that the surface cover 11 and the bottom shell 15 can be waterproof and moistureproof after being buckled, and the overall structure is as shown in Figure 1 .

[0175] The signal transmitter includes the surface cover 11, the control panel 13, the bottom shell 15 and the first waterproof elastic member 17, the surface cover 11 and the bottom shell 15 cooperatively form a containing cavity, the first waterproof elastic member 17 cooperatively forms a first sealing cavity with the surface cover 11 and the bottom shell 15, and the control panel 13 is located in the first sealing cavity. Under the action of the external force, the surface cover 11 moves towards the bottom shell 15 to deform the first waterproof elastic member 17, and the surface cover 11 returns to the original position under the restoring force of the first waterproof elastic member 17 after the external force disappears.

[0176] The first protruding part 115 is arranged on at least one of the surface cover 11 and the bottom shell 15, and the first protruding part 115 presses the first waterproof elastic member 17 to form the first sealing cavity in the buckled state of the surface cover and the bottom shell.

[0177] As shown in Figure 2As shown, one optional arrangement is that one of the face cover 11 and the bottom shell 15 is provided with the first protruding part 115, and the other is provided with the first mounting slot 157, and the first waterproof elastic member 17 is arranged in the first mounting slot 157. In the buckled state of the face cover 11 and the bottom shell 15, the first protruding part 115 presses the first waterproof elastic member 17, forming the first sealed cavity.

[0178] As shown, Figure 3 As shown, another optional arrangement is that the face cover 11 and the bottom shell 15 are both provided with the first protruding part 115. In the buckled state of the face cover 11 and the bottom shell 15, the first protruding part 115 on the face cover 11 and the first protruding part 115 on the bottom shell 15 press the first waterproof elastic member 17, forming the first sealed cavity. Specifically, the face cover 11 includes the face cover side wall 113 and the face plate 111, and the bottom shell 15 includes the bottom shell side wall 153 and the bottom plate 151. The first protruding part 115 is arranged on the face plate 111 and / or the bottom plate 151.

[0179] The side of the control panel 13 away from the bottom shell 15 is provided with a power supply mounting position for containing the power supply 18. The switch component 19 and the power supply mounting position are arranged on the same side of the control panel 13.

[0180] The signal transmitter provided by the above-mentioned embodiment one and embodiment two. The signal transmitter in the embodiment one does not include the first waterproof elastic member in the embodiment two. Referring to Figure 1 and Figure 2 As shown, the signal transmitter of the embodiment two of the present application includes the face cover 11, the control panel 13, the bottom shell 15, and the first waterproof elastic member 17. The face cover 11 includes the face plate 111 and the face cover side wall 113. The bottom shell 15 includes the bottom plate 151 and the bottom shell side wall 153. The face cover 11 and the bottom shell 15 are clamped to form a containing cavity A through the face cover side wall 113 and the bottom shell side wall 153. The first waterproof elastic member 17 is an elastic member, which is an elastic ring structure composed of an elastic material. In some embodiments, the first waterproof elastic member 17 is a silica gel ring or a rubber ring composed of silica gel or rubber. The face plate 111 is provided with the first protruding part 115. In the clamped state of the face cover 11 and the bottom shell 15, the first protruding part 115 presses the first waterproof elastic member 17 against the bottom plate 151, and the containing cavity A is divided into a sealed inner cavity A1 and an outer cavity A2. The control panel 13 is fixed on the bottom shell 15, and the switch component 19 is arranged at a position substantially at the center of the control panel 13 and connected with the control panel 13. The control panel 13 is further provided with a power supply mounting position for containing the power supply 18, and the power supply 18 is used to power the control panel 13. That is, the switch component 19 and the power supply 18 are both arranged between the control panel 13 and the face plate 111, and the control panel 13, the switch component 19, and the power supply 18 are all located in the inner cavity A1, so as to achieve the purpose of waterproofing. In some embodiments, the power supply 8 is a battery, such as a lithium battery or a solar panel.

[0181] AsFigure 2 As shown, the bottom plate 151 has a first mounting groove 157 formed by two protrusions, and the first waterproof elastic member 17 is arranged in the first mounting groove 157. The protruding portion 115 presses against the first waterproof elastic member 17, and the first waterproof elastic member 17 is elastically deformed to form a good sealing contact. The groove structure can effectively fix the first waterproof elastic member 17 and help to form a good sealing contact. In other embodiments, the groove structure is a groove on the surface of the bottom shell bottom plate (not shown in the figure). The sizes of the sealing member and the groove structure are reasonably designed so that the sealing member abuts against the side surface of the groove structure, which helps to further improve the sealing effect. That is, for the case of the groove structure formed by the protrusions, the sealing member abuts against the side surface of the protrusions on both sides to obtain a better sealing effect; for the case of the groove structure formed by the groove, the sealing member abuts against both sides of the groove to obtain a better sealing effect. Of course, the groove structure can also be omitted, and the sealing is realized only by the protruding portion of the face cover panel pressing against the sealing member.

[0182] It should be understood that the structures of the face cover panel and the bottom shell bottom plate for forming the sealing can be interchanged, and the effects are the same or similar. Specifically, the bottom shell bottom plate is provided with a protruding portion, and in the state that the face cover and the bottom shell are clamped, the protruding portion of the bottom shell bottom plate presses the sealing member against the face cover panel to divide the accommodation cavity into a sealed inner cavity and an outer cavity. Similarly, in some embodiments, the face cover panel has a groove structure formed by two protrusions, and the sealing member is arranged in the groove structure. The protruding portion of the bottom shell bottom plate presses against the sealing member to elastically deform the sealing member, thereby forming a good sealing contact. In some embodiments, the groove structure is a groove on the surface of the face cover panel. Similarly, the sizes of the sealing member and the groove structure are reasonably designed so that the sealing member abuts against the side surface of the groove structure, which helps to further improve the sealing effect. Of course, the groove structure can also be omitted, and the sealing is realized only by the protruding portion of the bottom shell bottom plate pressing against the sealing member.

[0183] In addition, the face cover panel and the bottom shell bottom plate can also adopt other structures to form the sealing contact. In some embodiments, as shown in Figure 3 The face cover panel is provided with a first protruding portion 115a, and the bottom shell bottom plate is also provided with a first protruding portion 115b. The two first protruding portions are arranged opposite to each other, and in the state that the face cover and the bottom shell are clamped, the first waterproof elastic member 17 abuts against the end surface of the first protruding portion and the end surface of the second protruding portion to form a sealing contact. In some embodiments, as shown in Figure 4As shown, the faceplate has a first protrusion 115c, and the bottom plate has a first protrusion 115d. The first waterproof elastic member 17 is fitted around the first protrusion of the bottom plate and fixed thereon. The first protrusion of the faceplate presses the first waterproof elastic member 17 against the bottom plate to form a sealing contact. Similarly, in some embodiments, the faceplate has a faceplate protrusion, the bottom plate has a protrusion, and a sealing member is fitted around the faceplate protrusion and fixed thereon. The protrusion of the bottom plate presses the sealing member against the faceplate to form a sealing contact.

[0184] In some implementations, such as Figure 5 As shown, the front cover panel has a first protrusion 115e, and the bottom shell plate has two first protrusions 115f and 115g, which are positioned opposite each other. A first waterproof elastic member 17 is fitted around the first protrusion 115f of the bottom shell plate and fixed thereon. The first waterproof elastic member 17 abuts against the end faces of the first protrusions 115e and 115g to form a sealed contact. The first protrusions 115g and 115f of the bottom shell plate are independent structures. In some embodiments, the first protrusions 115g and 115f of the bottom shell plate are combined to form different parts of a single structure, for example, as shown in... Figure 6 As shown, the first protrusion 115g and the first protrusion 115f on the bottom plate of the bottom shell combine to form a stepped structure 115h, wherein the higher step corresponds to the first protrusion 115f and the lower step corresponds to the first protrusion 115g. Similarly, in some embodiments, the protrusions on the top cover and the bottom shell can be reversed. That is, the bottom plate is provided with a first protrusion 115e, and the top cover panel is provided with two first protrusions 115f and 115g, and so on as described above.

[0185] The above methods all utilize the end face of the protrusion to press against the sealing element to form a sealing contact. In fact, besides the end face pressing method, the side face of the protrusion can also be used to press against the sealing element to form a sealing contact (not shown in the figures). For example, in some embodiments, the first protrusion on the faceplate and the first protrusion on the bottom plate are opposite each other and laterally offset by a certain distance. When the faceplate and bottom plate are engaged, the first waterproof elastic element abuts against the sides of the two first protrusions to form a sealing contact. Furthermore, in some embodiments, the bottom plate has a protrusion. When the faceplate and bottom plate are engaged, the first waterproof elastic element abuts against the side face of the protrusion and the inner wall of the faceplate sidewall to form a sealing contact. In some embodiments, the faceplate has a first protrusion. When the faceplate and bottom plate are engaged, the first waterproof elastic element abuts against the side face of the first protrusion and the inner wall of the bottom plate sidewall to form a sealing contact.

[0186] The cover 11, the bottom shell 15, and the first waterproof elastic element 17 surround and form a sealed inner cavity A1, so that the control board 13, the switch component 19, and the power supply 18 are all located in the inner cavity A1, thereby achieving the purpose of waterproofing. It should be understood that the term "sealed" here is a relative concept. Any structure that isolates external gases, moisture, dust, etc., and prevents external gases, moisture, dust, etc. from entering should fall within the scope of the "sealed cavity" referred to in this invention.

[0187] Furthermore, despite Figure 1 and Figure 2 The first waterproof elastic element shown is, for example, an elastic ring made of silicone or rubber. Furthermore, the seal is a sealing ring structure that includes the elastic ring. For example, the seal can be a sealing ring that combines a silicone or rubber ring with a plastic ring.

[0188] like Figure 2 As shown, the bottom shell sidewall 153 is located inside the top cover sidewall 113. The top cover sidewall 113 has a first hook 117, and the bottom shell sidewall 153 has a first groove 155. The first hook 117 and the first groove 155 engage to form a receiving cavity A. Specifically, the first hook 117 is a protrusion formed on the inner side of the top cover sidewall 113, and the first groove 155 is a groove formed on the outer side of the bottom shell sidewall 153. The first hook 117 of the top cover sidewall and the first groove 155 of the bottom shell sidewall engage to form the receiving cavity A. Furthermore, the first hook 117 and the first groove 155 can also adopt other structures. For example, in some embodiments, the first groove can be provided on the top cover and the first hook can be provided on the bottom shell. The first groove can also be a positioning hole structure. In some embodiments, the first hook can be provided on both the top cover and the bottom shell, respectively, as protrusions on the top cover sidewall and the bottom shell sidewall.

[0189] When the cover and the bottom shell are fastened together, the side wall of the bottom shell can be located inside the side wall of the cover, or the side wall of the bottom shell can be located outside the side wall of the cover. Depending on the fastening relationship between the cover and the bottom shell, the first hook and the first groove mentioned above are respectively set on the outside or inside of the side wall.

[0190] like Figure 2 As shown, through the engagement structure between the cover 11 and the bottom shell 15, pressing any position on the panel 111 will cause the panel 111 to move downwards, thereby triggering the switch component 19. For example, when pressing the approximate center position of the panel 111, the first engagement portion moves downwards relative to the second engagement portion, and the panel 111 presses against the switch component 19 to trigger it. When pressing the edge position of the panel 111, the panel 111 rotates around the engagement structure on the opposite side of the pressing position as a fulcrum, and the first engagement portion near the pressing side moves downwards relative to the second engagement portion, and the panel 111 presses against the switch component 19 to trigger it.

[0191] In the case that the side wall of the face cover is located in the side wall of the bottom shell, the face cover can further comprise a peripheral side wall arranged at the periphery of the side wall of the face cover and a face cover panel extension (not shown in the figure) between the peripheral side wall and the side wall of the face cover, the peripheral side wall surrounds the side wall of the bottom shell and the side wall of the face cover, together with the face cover panel extension, effectively shielding the structure of the side wall of the bottom shell and the side wall of the face cover engaged, improving the overall visual effect of the product.

[0192] As shown in Figure 2 the control board 13 is located at the approximate center of the signal transmitter, and the switch component 19 is located at the approximate center of the control board 13. The control board 13 is provided with a signal generator and a key instruction generating circuit, and the panel 111 is a rigid structure. When the panel 111 is pressed, the first waterproof elastic member 17 is elastically deformed, the panel 111 is displaced downward, and the switch component 19 is pressed to be triggered, the key instruction generating circuit in the control board 13 is turned on and generates a corresponding key instruction, and the signal generator further completes the sending of the wireless control signal based on the key instruction. After the external force is removed, under the joint action of the elastic restoring force of the first waterproof elastic member 17 and the upward thrust generated by the reset of the switch component 19, the panel 111 and the first waterproof elastic member 17 return to the initial state, the switch component 19 resets, and the key instruction generating circuit in the control board 13 is turned off. It should be understood that the triggered state of the switch component 19 corresponds to the state that the key instruction generating circuit is turned on, and the reset state of the switch component 19 corresponds to the state that the key instruction generating circuit is turned off.

[0193] In some embodiments, the first waterproof elastic member 17 is an elastic member, which mainly acts by elastic deformation, on the one hand, to provide movement space for the panel 111, so that the panel 111 can be displaced downward under the action of external force to trigger the switch component 19, and on the other hand, to provide elastic restoring force for the reset of the panel 111 after the external force is removed. In addition to this, the first waterproof elastic member 17 can also undertake the function of waterproof sealing as described above.

[0194] It should be understood that the triggering of the switch component specifically refers to the start of the work of the switch component. In the triggered state of the switch component, the corresponding circuit is turned on, that is, the key instruction generating circuit in the control board is turned on and generates a corresponding key instruction. Correspondingly, in the untriggered state of the switch component, the corresponding circuit is in the off state.

[0195] In some embodiments, the control board 13 is a printed circuit board (PCB). The panel 111 has elasticity in at least a partial region and can be elastically deformed under an external force. In this case, the panel 111 is pressed to be elastically deformed, and then the switch component 19 is triggered. In this case, when the panel 111 is pressed, the first waterproof elastic member 17 can also be elastically deformed as described above, and correspondingly, when the external force is removed, the force for restoring the panel 111 to the initial state can come from the elastic restoring force of the first waterproof elastic member 17 and the upward thrust generated by the reset of the switch component 19 in addition to the elastic restoring force of the panel 111 itself.

[0196] The signal transmitter of the embodiment can be provided with the first waterproof elastic member, and the first waterproof elastic member is matched with the cover and the bottom shell to form the first sealed cavity. The control board and other electrical elements are arranged in the sealed cavity to achieve waterproof and dustproof, meet the use requirements in a humid environment or a dusty environment. When the cover is subjected to an external force, the first waterproof elastic member can be deformed to facilitate the movement of the cover relative to the bottom shell. After the external force disappears, the first waterproof elastic member has an elastic restoring force to reset the cover. The cover is directly matched with the bottom shell, and a full-pressing structure is formed by the support of the switch component. The structure is simple. Meanwhile, the elastic deformation characteristics of the first waterproof elastic member are fully utilized. On one hand, the cover panel is effectively supported, and on the other hand, the cover panel can be displaced downward under the action of the external force to trigger the switch component through the elastic deformation of the sealing member. In addition, the structure of the sealing member, the cover and the bottom shell can be reasonably designed to form a sealed cavity to achieve the waterproof purpose. In this case, the cover panel is used as an operation panel and forms a sealed waterproof structure with the bottom shell and the sealing member. The overall structure is simple, compact and light.

[0197] Embodiment three

[0198] The signal transmitter provided by the embodiment three has the structure as shown in Figure 7 and Figure 8 The difference between the signal transmitter and the signal transmitter provided by the embodiment two is that the signal transmitter further comprises a lower cover 12 and a second waterproof elastic member 14. The second waterproof elastic member 14 is matched with the bottom shell 15 and the lower cover 12 to form a second sealed cavity.

[0199] The second sealed cavity and the first sealed cavity can be in communication with each other or independently arranged. When the second sealed cavity and the first sealed cavity are in communication with each other, the second sealed cavity and the first sealed cavity are communicated through the through hole 158 formed on the bottom shell 15. The second sealed cavity can be used to place a battery and other electronic devices. The second sealed cavity can be independently opened to facilitate the replacement of the electronic devices of the battery.

Pressing any position of the face plate 111, the face plate 111 is moved towards the bottom shell 15, and the first waterproof elastic member 17 is deformed. The middle of the face plate 111 abuts against and triggers the switch component 19. After the external force disappears, the face cover 11 is reset under the restoring force generated by the first waterproof elastic member 17.

The control panel 13 is connected with a switch component 19, under the action of an external force, the switch component 19 is pressed by the face cover 11 to be triggered.

[0209] In some embodiments, the first waterproof elastic member 17 and the second waterproof elastic member 14 are elastic members, which are elastic ring structures composed of elastic materials, such as silica gel rings or rubber rings composed of silica gel or rubber. In some embodiments, the power supply 18 is a battery, such as a lithium battery or a button cell.

[0210] Specifically, the bottom shell bottom plate 151 has a bottom shell through hole 158, the bottom shell inner wall 152 is located at the bottom shell through hole 158, the inner side of the bottom shell inner wall 152 is formed with a bottom shell inner plate 156, the control panel 13 is arranged on the bottom shell inner plate 156, the edge of the control panel 13 is clamped with the limiting portion of the bottom shell inner wall 152, so as to fix the control panel 13 on the bottom shell inner plate 156. At this time, the bottom shell inner wall 152 simultaneously has the functions of limiting the first waterproof elastic member 17 and fixing the control panel. It should be understood that the control panel 13 can also be fixed with the bottom shell 15 through other ways, such as gluing or rivets.

[0211] The power supply installation position of the control board 13 is arranged at a position corresponding to the through hole 158 of the bottom shell, for containing the power supply. The face cover side wall 113 is located outside the bottom shell side wall 153, and the face cover side wall 113 has a first clamping hook 117, which is a protrusion formed on the inner side of the face cover side wall 113. The bottom shell side wall 153 has a first clamping groove 155, which is a groove formed on the outer side of the bottom shell side wall 153. The face cover 11 and the bottom shell 15 are clamped by the first clamping groove 155 and the first clamping groove 155. The bottom shell bottom plate 151 also has a protrusion 154 formed thereon, and the protrusion 154 and the inner wall 152 of the bottom shell form a groove structure, in which the first waterproof elastic member 17 is arranged. The face cover panel 111 is provided with a first protruding portion 115. In the clamped state of the face cover 11 and the bottom shell 15, the first protruding portion 115 presses the first waterproof elastic member 17 against the bottom shell bottom plate 151, so that the first waterproof elastic member 17 is elastically deformed, thereby forming a good sealing contact.

[0212] The lower cover 12 includes a back plate 121 and a lower cover side wall 123. The back plate 121 includes a first portion 127 located on the inner side of the lower cover side wall 123 and a second portion 129 located on the outer side of the lower cover side wall 123. The second portion 129 is further provided with a fourth clamping hook 125. The bottom shell side wall 153 is provided with a fourth clamping groove 159. The fourth clamping hook 125 passes through the opening on the bottom shell and cooperates with the fourth clamping groove 159 to clamp the lower cover and the bottom shell. The fourth clamping groove 159 can also be designed as a hole structure. Alternatively, the bottom shell side wall and the lower cover can also be clamped and fixed by other structures.

[0213] The second waterproof elastic member 14 is located between the lower cover side wall 123 and the inner wall 152 of the bottom shell. The lower cover side wall 123 has a groove structure for accommodating the second waterproof elastic member 14. In the clamped state of the lower cover 12 and the bottom shell 15, the second waterproof elastic member 14 abuts against the groove structure of the lower cover side wall 123 and the side surface of the inner wall 152 of the bottom shell to form a sealing contact. In addition, the groove structure for accommodating the second waterproof elastic member 14 can also be arranged on the inner wall 152 of the bottom shell, or the lower cover side wall 123 and the inner wall 152 of the bottom shell can both have the groove structure for accommodating the second waterproof elastic member 14. Furthermore, the groove structure is not necessarily required, and the groove structure can be omitted or replaced by other structures.

[0214] As Figure 8As shown, the face cover 11, the first waterproof elastic member 17, the bottom shell 15, the second waterproof elastic member 14 and the lower cover 12 together enclose a sealed cavity. The control board 13 is fixed on the bottom shell 15 at a position approximately in the center of the signal transmitter, the switch component 19 is connected with the control board 13 at a position approximately in the center of the control board 13, and the battery 113 and the switch component 19 are respectively arranged on two sides of the control board 13. Pressing any position of the face cover panel 111 can cause the face cover panel 111 to move downward, and then trigger the switch component 19. For example, when pressing a position approximately in the center of the face cover panel 111, the first clamping hook 117 moves downward relative to the first clamping groove 155 as a whole, and the face cover panel 111 presses the switch component 19 to trigger it. When pressing a position at the edge of the face cover panel 111, the face cover panel 111 rotates around the clamping structure on the side opposite to the pressing position as a fulcrum, the first clamping hook 117 on the side close to the pressing position moves downward relative to the first clamping groove 155, and the face cover panel 111 presses the switch component 19 to trigger it.

[0215] The face cover of the embodiment serves as an operation panel and cooperates with the bottom shell to form a sealed waterproof structure, and the lower cover is detachable. When the lower cover is removed, the power supply is exposed through the first bottom shell opening, and the power supply can be directly disassembled and installed, which is very convenient, and the overall structure is simple, small and light.

[0216] The difference between the embodiment and the second embodiment lies in the setting of the lower cover and the second waterproof elastic member and the mounting relationship with the related components, and the clamping structure and the sealing structure can also be set in many different forms. For the mounting relationship of the first waterproof elastic member with the bottom shell, the panel and other related components and the description of the related structure, please refer to the description in the second embodiment, which will not be repeated here. The other structures in the embodiment have been described in the second embodiment, and will not be described in detail.

[0217] Embodiment Four

[0218] The signal transmitter provided in the fourth embodiment of the present application has a structure as shown in Figure 9 and Figure 10 The difference between the signal transmitter provided in the fourth embodiment and the signal transmitter provided in the second embodiment lies in that the fourth embodiment further comprises a middle cover 16 arranged between the face cover 11 and the control board 13. Under the action of external force, the face cover 11 and the middle cover 16 can move towards the bottom shell by not more than a set distance, and the switch component 19 is triggered through the middle cover 16. The middle cover arranged between the face cover and the control board and the switch component can trigger the detection switch through the middle cover, and the middle cover can shield and protect the internal electronic devices, facilitate the disassembly and assembly of the face cover, and avoid damaging the electronic devices during the disassembly and assembly of the face cover.

[0219] The middle part of the face cover 11 is provided with a pushing arm 112 which abuts against the middle cover 16. The middle cover plate 161 of the middle cover 16 is made of elastic material. Pressing any position of the face plate 111 on the face cover 11 makes the pushing arm 112 move, and the middle cover plate 161 is elastically deformed to abut against and trigger the switch component 19.

[0220] The face cover 11 comprises a face cover side wall 113 and a face plate 111, and the bottom shell comprises a bottom shell side wall 153 and a bottom plate 151. One of the bottom shell side wall 153 and the face cover side wall 113 is provided with a first clamping hook 117, and the other is provided with a first clamping groove 155 which is shaped to match the first clamping hook. The height of the first clamping hook is less than the height of the first clamping groove. After the first clamping hook and the first clamping groove are clamped, the first clamping hook can move in the first clamping groove by no more than a set distance.

[0221] The middle cover 16 comprises a middle cover side wall 163 and a middle cover plate 161. The bottom shell side wall is provided with a second clamping hook 1510, and the middle cover side wall is provided with a third clamping hook 167. After the bottom shell 15 and the middle cover 16 are clamped, the second clamping hook 1510 and the third clamping hook 167 cooperate to make the middle cover move towards the bottom shell by no more than a set distance.

[0222] The mounting and clamping structures between the face cover 11 and the bottom shell 15, and between the bottom shell 15 and the middle cover 16 can have various specific designs, which can be referred to the related descriptions in the previous embodiments.

[0223] After the face cover 11 and the bottom shell 15 are clamped and the middle cover 16 and the bottom shell 15 are clamped, pressing the middle part of the face plate 111 can make the face cover 11 move towards the bottom shell as a whole, so that the face plate 111 abuts against the middle cover 16 and triggers the switch component 19 through the middle cover 16. Pressing a position of the face plate 111 away from the center can make the side of the face plate 111 which is pressed pivot relative to the side which is away from the pressed position, so that the face plate 111 abuts against the middle cover and triggers the switch component through the middle cover 16.

[0224] In addition to the middle cover 16, the signal transmitter of the embodiment further comprises a first waterproof elastic member 17. The first waterproof elastic member 17 cooperates with the middle cover 16 and the bottom shell 15 to form a first sealed cavity, and the control board 13 is located in the first sealed cavity. Under the action of external force, the face cover 11 and the middle cover 16 move towards the bottom shell 15 to make the first waterproof elastic member 17 deform. After the external force disappears, the face cover 11 and the middle cover 16 are reset under the restoring force generated by the first waterproof elastic member 17.

[0225] The face cover includes a face cover side wall and a face plate, the switch component 19 is located between the face plate 111 and the control plate 13, is arranged in the middle of the control plate 3, and the face plate 111 is pressed at any position, and the face plate 111 is moved to the bottom shell 15 direction at the pressed position, so that the first waterproof elastic piece 17 is deformed, the middle of the face plate 111 abuts against the middle cover 16, the switch component is triggered through the middle cover 16, and after the external force disappears, the face cover 11 and the middle cover 16 are reset under the restoring force generated by the first waterproof elastic piece 17.

[0226] In the embodiment, after the middle cover 16 is arranged, the first waterproof elastic piece 17 cooperates with the middle cover 16 and the bottom shell 15 to form a seal, instead of cooperating with the face cover 11 to form a seal, so that the face cover is removed without affecting the waterproof effect, different face covers are convenient to replace, the face cover is designed in various styles, and the waterproof function does not need to be considered.

[0227] The cooperation of the middle cover 16 and the bottom shell 15 with the first waterproof elastic piece 17 can be in various modes, a first protruding part 115 can be arranged on at least one of the middle cover 16 and the bottom shell 15, and in the buckling state of the middle cover and the bottom shell, the first protruding part presses the first waterproof elastic piece to form a first sealing cavity. The middle cover 16 includes a middle cover side wall 163 and a middle cover plate 161, the bottom shell 15 includes a bottom shell side wall 153 and a bottom plate 151, and the first protruding part 165 is arranged on the middle cover plate 161 and / or the bottom plate 151.

[0229] One possible implementation mode is that the middle cover 16 and the bottom shell 15 are both provided with the first protruding part 165, and in the buckling state of the middle cover 16 and the bottom shell 15, the first protruding part on the middle cover 16 and the first protruding part on the bottom shell 15 press the first waterproof elastic piece 17 to form the first sealing cavity.

[0230] The side, away from the bottom shell 15, of the control plate 13 is provided with a power supply mounting position for containing a power supply, and the switch component 19 and the power supply mounting position are arranged on the same side of the control plate 13.

[0231] Referring to Figure 9 and Figure 10 , the exploded view and the cross-sectional structure schematic view of the signal transmitter are shown. Different from the structure shown in Figure 1 and Figure 2 , the signal transmitter shown in FIG. 9 and Figure 10 further includes a top cover arranged above the upper cover.

[0232] Specifically, as Figure 9And Figure 10 As shown in FIG. 1, the signal transmitter comprises a middle cover 16, a control board 13, a bottom shell 15, a first waterproof elastic member 17 and a face cover 11. The middle cover 16 comprises a middle cover plate 161 and a middle cover sidewall 163, and the bottom shell 15 comprises a bottom shell bottom plate 151 and a bottom shell sidewall 153. The face cover 11 comprises a face cover plate 111, a face cover sidewall 113 and a push arm 112. The middle cover 16 and the bottom shell 15 form a receiving cavity A by the engagement of the middle cover sidewall 163 and the bottom shell sidewall 153. The middle cover plate 161 is provided with a first protruding part 165, and in the engaged state of the middle cover 16 and the bottom shell 15, the first protruding part 165 presses the first waterproof elastic member 17 against the bottom shell bottom plate 151, thereby dividing the receiving cavity A into a sealed inner cavity A1 and an outer cavity A2.

[0233] As shown in FIG. 2, the first waterproof elastic member 17 is pressed against the bottom shell bottom plate 151 by the first protruding part 165, and the first waterproof elastic member 17 is in elastic deformation. Figure 10 As shown in FIG. 3, the bottom shell bottom plate 151 has a groove structure formed by two protrusions, and the first waterproof elastic member 17 is arranged in the groove structure. The first protruding part 165 presses the first waterproof elastic member 17, and the sealing member is in elastic deformation, thereby forming a good sealing contact. Figure 1 Figure 2 Similarly to the embodiments shown in FIGS. 1-3, the first waterproof elastic member 17 and the upper cover plate and the bottom shell plate can adopt various sealing abutting modes, i.e., the abutting mode shown in FIG. 4 and the abutting mode shown in FIG. 5 and the variant embodiments thereof. Figure 1 Figure 2 The abutting mode shown in FIG. 4 and the abutting mode shown in FIG. 5 and the variant embodiments thereof are still applicable in the structure shown in FIG. 6, and thus will not be described herein. Figure 9 Figure 10 As shown in FIG. 7, the middle cover sidewall 163 has a third clamping hook 167, and the bottom shell sidewall 153 has a second clamping hook 1510.

[0234] As shown in FIG. 8, the middle cover sidewall 163 has a third clamping hook 167, and the bottom shell sidewall 153 has a second clamping hook 1510. The third clamping hook 167 and the second clamping hook 1510 are engaged to form the receiving cavity A. The face cover sidewall 113 has a first clamping hook 117, and the bottom shell sidewall 153 further has a first clamping groove 155. The first clamping hook 117 and the first clamping groove 155 are engaged. Figure 10

[0235] ​​​​Specifically, the middle cover side wall 163 is located inside the face cover side wall 113, the bottom shell side wall 153 is located between the middle cover side wall 163 and the face cover side wall 113, the third clamping hook 167 is a protrusion formed on the outer side of the middle cover side wall 163, and the second clamping hook 1510 is a protrusion formed on the inner side of the bottom shell side wall 153. In addition, the third clamping hook 167 and the second clamping hook 1510 can also adopt other structures. For example, in some embodiments, the third clamping hook 167 is a protrusion formed on the outer side of the middle cover side wall, and the second clamping hook 1510 is a groove formed on the inner side of the bottom shell side wall. In some embodiments, the third clamping hook 167 is a groove formed on the outer side of the middle cover side wall, and the second clamping hook 1510 is a protrusion formed on the inner side of the bottom shell side wall. In some embodiments, the third clamping hook 167 is a protrusion formed on the outer side of the middle cover side wall, and the second clamping hook 1510 is a positioning hole formed on the bottom shell side wall. In some embodiments, the third clamping hook 167 is a positioning hole formed on the middle cover side wall, and the second clamping hook 1510 is a protrusion formed on the inner side of the bottom shell side wall. Different structures can be arranged as needed.

[0236] Specifically, the first clamping hook 117 is a protrusion formed on the inner side of the face cover side wall 113, and the first clamping groove 155 is a groove formed on the outer side of the bottom shell side wall 153. In addition, the first clamping hook 117 and the first clamping groove 155 can also adopt other structures. For example, in some embodiments, the first clamping hook 117 is a protrusion formed on the inner side of the face cover side wall 113, and the first clamping groove 155 is a protrusion formed on the outer side of the bottom shell side wall 153. In some embodiments, the first clamping hook 117 is a groove formed on the inner side of the face cover side wall 113, and the first clamping groove 155 is a protrusion formed on the outer side of the bottom shell side wall 153. In some embodiments, the first clamping hook 117 is a protrusion formed on the inner side of the face cover side wall 113, and the first clamping groove 155 is a positioning hole formed on the bottom shell side wall 153. In some embodiments, the first clamping hook 117 is a positioning hole formed on the face cover side wall 113, and the first clamping groove 155 is a protrusion formed on the outer side of the bottom shell side wall 153.

[0237] As Figure 10As shown, the control board 13 is located at the approximate center of the signal transmitter, and the switch component 19 is located at the approximate center of the control board 13. The face cover panel 111 and the middle cover plate 161 are both rigid structures. When the face cover panel 111 is pressed, the face cover panel 111 pushes the middle cover plate 161 through the pushing arm 112, the first waterproof elastic member 17 is elastically deformed, the face cover panel 111 and the middle cover plate 161 are both displaced downward, pressing the switch component 19, so that the switch component 19 is triggered, the key instruction generating circuit in the control board is turned on and generates a corresponding key instruction, and the signal generator further completes the sending of the wireless control signal based on the key instruction. After the external force is removed, under the combined action of the elastic restoring force of the first waterproof elastic member 17 and the upward thrust generated by the reset of the switch component 109, the middle cover plate 161, the first waterproof elastic member 17 and the face cover panel 111 return to the initial state, and the switch component 19 is reset, and the key instruction generating circuit in the control board is turned off.

[0238] Similarly to the foregoing, the first waterproof elastic member 17 is an elastic member, which mainly acts by elastic deformation, on the one hand, to provide movement space for the face cover panel 111 and the middle cover plate 161, so that the face cover panel 111 and the middle cover plate 161 can be displaced downward under the action of an external force to trigger the switch component 19, and on the other hand, to provide elastic restoring force for the reset of the face cover panel 111 and the middle cover plate 161 after the external force is removed. In addition, the first waterproof elastic member 17 can also assume the function of waterproof sealing as described above.

[0239] In some embodiments, the middle cover plate 161 has elasticity at least in part of the area, and can be elastically deformed under the action of an external force. In this case, when the face cover panel 111 is pressed, the middle cover plate 161 is elastically deformed under the action of the pushing arm 112, and then the switch component 19 is triggered. In this case, when the face cover panel 111 is pressed, in addition to the elastic deformation of the middle cover plate 161, the first waterproof elastic member 17 can also be elastically deformed as described above. Correspondingly, when the external force is removed, the force for returning the face cover panel 111 to the initial state can come not only from the elastic restoring force of the middle cover plate 161, but also from the elastic restoring force of the first waterproof elastic member 17 and the upward thrust generated by the reset of the switch component 19.

[0240] By the structure that the face cover 11 is engaged with the bottom shell 15, pressing any position of the face cover panel 111 can make the face cover panel 111 produce downward displacement, and further trigger the switch component 19. For example, when the position of the face cover panel 111 is pressed in the approximate center, the first clamping hook is displaced downward relative to the first clamping slot as a whole, the pushing arm 112 drives the middle cover plate 161 to press against the switch component 19 to make it trigger. When the edge position of the face cover panel 111 is pressed, the face cover panel 111 rotates with the engaging structure on the opposite side of the pressing position as a fulcrum, the first clamping hook close to the pressing side is displaced downward relative to the first clamping slot, the pushing arm 112 drives the middle cover plate 161 to press against the switch component 19 to make it trigger.

[0241] The combination and implementation of other components, for example, the first waterproof elastic member 17 and the implementation of the sealing pressed by the first waterproof elastic member 17, are the same as those shown in the embodiments of Figure 1 and Figure 2 and can be directly used herein, and thus will not be described herein again. In addition, the related structure in the present embodiment has been described in any one of the preceding embodiments, and thus will not be described herein again.

[0242] In the present embodiment, the middle cover, the bottom shell and the sealing member are used as the basis to form a signal transmitter module with complete functions, and then the face cover is further added on the basis. Since the face cover does not undertake the functions related to waterproof, the design and material selection of the face cover are more flexible, and the user can conveniently reprocess the signal transmitter module according to actual needs and preferences to obtain different appearances, so as to meet the use needs of different users.

[0243] Embodiment Five

[0244] The signal transmitter provided in the present embodiment has the structure as shown in Figure 11 and Figure 12 The difference between the signal transmitter provided in the present embodiment and the signal transmitter provided in the fourth embodiment is that the signal transmitter provided in the present embodiment further includes the lower cover 12 and the second waterproof elastic member 14; the second waterproof elastic member 14 cooperates with the bottom shell 15 and the lower cover 12 to form a second sealing cavity. The second sealing cavity and the first sealing cavity can be in communication with each other or can be independently arranged. When the second sealing cavity and the first sealing cavity are in communication with each other, the second sealing cavity and the first sealing cavity are communicated through the bottom shell through hole 158 formed in the bottom shell 15.

[0245] The mounting relationship between the second waterproof elastic member 14 and the lower cover 12 and the bottom shell 15 can be various.

[0246] One possible implementation is that the lower cover 12 includes the lower cover side wall 123 and the back plate 121, and the bottom shell 15 further includes the bottom shell inner wall 152 and the bottom shell inner plate 156; the second mounting slot is arranged on the lower cover side wall 123, and the second waterproof elastic member 14 is arranged in the second mounting slot; the bottom shell inner wall 152 abuts against and compresses the second waterproof elastic member to form the second sealing cavity.

[0247] In a possible implementation, the lower cover 12 comprises a lower cover side wall 123 and a back plate 121, and the bottom shell 15 further comprises a bottom shell inner wall 152 and a bottom shell inner plate 156; the second mounting groove is arranged on the bottom shell inner wall 152, and the second waterproof elastic member 14 is arranged in the second mounting groove 122, and the lower cover side wall 123 abuts against and compresses the second waterproof elastic member, thereby forming a second sealing cavity.

[0249] The bottom shell inner plate 156 of the bottom shell 15 is provided with a bottom shell through hole 158 which communicates the first sealing cavity and the second sealing cavity. The switch component 19 is located in the first sealing cavity between the face cover 11 and the control plate 13; the side of the control plate 13 close to the bottom shell 15 is provided with a power supply mounting position, and the power supply mounting position is located in the second sealing cavity.

[0250] In the embodiment, the first waterproof elastic member and the second waterproof elastic member can be elastic sealing rings. Alternatively, other sealing rings or elastic rings can also be used.

[0251] Figure 11 and Figure 12 are respectively an exploded view and a cross-sectional structural schematic view of the signal transmitter of the embodiment. The main difference between the signal transmitter and the signal transmitter shown in Figure 7 and Figure 8 is that Figure 11 and Figure 12 the signal transmitter further comprises a face cover arranged above the middle cover.

[0252] Specifically, as shown in Figure 11 and Figure 12 the signal transmitter comprises a middle cover 16, a face cover 11, a control plate 13, a bottom shell 15, a lower cover 12, and a first waterproof elastic member 17 and a second waterproof elastic member 14. The middle cover 16 comprises a middle cover plate 161 and a middle cover side wall 163, the face cover 11 comprises a face cover panel 111, a face cover side wall 113 and a push arm 112, the bottom shell 15 comprises a bottom shell bottom plate 151, a bottom shell side wall 153 and a bottom shell inner wall 152, and the bottom shell side wall 153 is located at the periphery of the bottom shell inner wall 152. The first waterproof elastic member 17 cooperates with the middle cover 16 and the bottom shell 15, and the second waterproof elastic member 14 cooperates with the lower cover 12 and the bottom shell 15, thereby forming a sealing cavity. The control plate 13 is located in the sealing cavity, and the side of the control plate 13 away from the middle cover 16 is provided with a power supply mounting position for containing the power supply 18. The control plate 13 is connected with the switch component 19.

[0253] The face cover side wall 113 is located outside the middle cover side wall 163, the bottom shell side wall 153 is located between the middle cover side wall 163 and the face cover side wall 113, the middle cover side wall 163 has a third hook 167 which is a protrusion formed on the outside of the middle cover side wall 163, the bottom shell side wall 153 has a second hook 1510 which is a protrusion formed on the inside of the bottom shell side wall 153, the middle cover 16 and the bottom shell 15 are clamped by the third hook 167 and the second hook 1510. The face cover side wall 113 has a first hook 117 which is a protrusion formed on the inside of the face cover side wall 113, the bottom shell side wall 153 has a first slot 155 which is a groove formed on the outside of the bottom shell side wall 153, the face cover 11 and the bottom shell 15 are clamped by the first hook 117 and the first slot 155.

[0254] Figure 12 The structure of the third hook 167 and the second hook 1510, and the structure of the first hook 117 and the first slot 155 are only used as examples, and it should be understood that the third hook 167 and the second hook 1510 can also adopt the above-mentioned modified embodiments, and the first hook 117 and the first slot 155 can also adopt the above-mentioned modified embodiments. Since it has been described in detail above, it will not be repeated here.

[0255] The bottom shell bottom plate 151 has a groove structure formed by two protrusions, the first waterproof elastic piece 17 is arranged in the groove structure, the middle cover plate 161 is provided with a first protruding portion 165, and in the clamped state of the middle cover 16 and the bottom shell 15, the first protruding portion 165 presses the first waterproof elastic piece 17 against the bottom shell bottom plate 151, so that the first waterproof elastic piece 17 is elastically deformed, thereby forming a good sealing contact. Similarly, the first waterproof elastic piece 17 and the middle cover 16 and the bottom shell 15 can also adopt the above-mentioned other abutting modes, since it has been described in detail above, it will not be repeated here.

[0256] The specific structure of the lower cover 12 and the abutting mode and clamping mode of the lower cover 12 and the bottom shell 15 have been described in detail in the embodiments of Figure 1 and Figure 2 The structures in Figure 11 and Figure 12 are also applicable, and will not be repeated here.

[0257] As Figure 12As shown, the control board 13 is fixed to the bottom shell 15 (as mentioned before, the fixing can be by gluing or rivet connection) at a position approximately in the center of the signal transmitter, and the switch component 19 is located approximately in the center of the control board 13. When the face cover panel 111 is pressed and the face cover panel 111 is displaced downward, the pushing arm 112 pushes the middle cover plate 161, and the first waterproof elastic member 17 is elastically deformed, and the middle cover plate 161 is correspondingly displaced downward and pushes the switch component 19, so that the switch component 19 is triggered, the key instruction generating circuit in the control board is turned on and generates a corresponding key instruction, and the signal generator further completes the sending of the wireless control signal based on the key instruction. After the external force is removed, under the combined action of the elastic restoring force of the first waterproof elastic member 17 and the upward thrust generated by the reset of the switch component 19, the middle cover plate 161, the first waterproof elastic member 17 and the face cover panel 111 return to the initial state, and the switch component 19 is reset, and the key instruction generating circuit in the control board is turned off.

[0258] Similarly as mentioned before, the middle cover plate 161 can be made of rigid material or elastic material. When the middle cover plate 161 is made of elastic material, the face cover panel 111 is pressed and the middle cover plate 161 is elastically deformed under the action of the pushing arm 112, and then the switch component 19 is triggered. In this case, when the face cover panel 111 is pressed, in addition to the elastic deformation of the middle cover plate 161, the first waterproof elastic member 17 can also be elastically deformed as mentioned before, and correspondingly, when the external force is removed, the force for returning the face cover panel 111 to the initial state can come from the elastic restoring force of the first waterproof elastic member 17 in addition to the elastic restoring force of the middle cover plate 161 and the upward thrust generated by the reset of the switch component 19.

[0259] Through the structure of the clamping of the face cover 11 and the bottom shell 15, any position of the face cover panel 111 pressed can make the face cover panel 111 be displaced downward, and then the switch component 19 is triggered. For example, when the approximately central position of the face cover panel 111 is pressed, the first clamping hook 117 is displaced downward as a whole relative to the first clamping slot 155, the pushing arm 112 drives the middle cover plate 161 to press the switch component 19 to be triggered. When the edge position of the face cover panel 111 is pressed, the face cover panel 111 rotates around the clamping structure on the opposite side of the pressing position as a fulcrum, and the first clamping hook 117 on the pressing side is displaced downward as a whole relative to the first clamping slot 155, the pushing arm 112 drives the middle cover plate 161 to press the switch component 19 to be triggered.

[0260] The embodiment is based on the middle cover, the bottom shell, the lower cover, the first waterproof elastic member and the second waterproof elastic member, and after forming the signal transmitter module with complete functions, the face cover is further added. Since the face cover does not undertake the waterproof related functions, the design and material selection are more flexible, and the user can reprocess the signal transmitter module according to actual needs and preferences to obtain different appearances, so that the use needs of different users can be met.

[0261] The related structure in the embodiment has been described in any one of the preceding embodiments, and will not be described herein again.

[0262] Embodiment six

[0263] The signal transmitter provided in the embodiment six has the structure as shown in Figure 13 and Figure 14 The difference between the signal transmitter as shown in Figure 1 and Figure 2 lies in that the waterproof structure is not the first waterproof elastic member, but the elastic buffer member. The signal transmitter provided in the embodiment six further comprises the elastic buffer member 27 between the face cover 11 and the switch component 19, the elastic buffer member 27 cooperates with the face cover 11 and the bottom shell 15 to form the first sealing cavity, and the control board 13 is located in the first sealing cavity. Under the action of external force, the face cover 11 moves towards the bottom shell 15 to make the elastic buffer member 27 deform, and the switch component is triggered through the elastic buffer member 27. After the external force disappears, the face cover 11 is reset under the restoring force of the elastic buffer member 27. The signal transmitter provided in the embodiment six is the signal transmitter as shown in Figure 13 and 14 without the lower cover, that is, the bottom shell is an integral body, which is similar to the bottom shell as shown in Figure 1 and Figure 2 .

[0264] The elastic buffer member 27 comprises the elastic cover body 271 and the elastic outer edge 273. The face cover 11 is provided with the first protruding part 115, and the bottom shell 15 is provided with the second protruding part. The second protruding part can be a protruding structure separately provided, or can borrow the inner wall 152 of the bottom shell. The second protruding part abuts against the inner surface of the side wall of the elastic cover body 271, and the first protruding part 115 presses the elastic outer edge against the panel of the bottom shell 15 to form the first sealing cavity. Figure 14 The bottom shell inner wall is taken as an example for illustration. The specific structure and design of the elastic buffer member are described in the following embodiment seven.

[0265] The side of the control board 13 away from the bottom shell 15 is provided with the power supply mounting position for containing the power supply 18. The switch component 19 and the power supply mounting position are provided on the same side of the control board 13.

[0266] The signal transmitter in the embodiment is waterproofly sealed by the elastic buffer, which is arranged between the face cover and the switch component, can support the face cover, and avoid triggering the switch component when the face cover is not subjected to external force; the elastic buffer cooperates with the face cover and the bottom shell to form a first sealing cavity, the control panel and other electrical elements are arranged in the sealing cavity, waterproof and dustproof are realized, and the use requirement in a humid environment or a dusty environment is met. When the face cover is subjected to external force, the elastic buffer is deformed by being pressed by the face cover, the switch component is triggered by the deformation of the elastic buffer, and the elastic buffer is deformed to recover after the external force disappears, so that the face cover is reset.

[0267] Embodiment seven

[0268] The signal transmitter provided in the embodiment seven has the structure as shown in Figure 13 and 14 The difference between the signal transmitter provided in the embodiment seven and the signal transmitter provided in the embodiment six is that the signal transmitter provided in the embodiment seven further comprises a lower cover 12 and a second waterproof elastic element 14; the second waterproof elastic element 14 cooperates with the bottom shell 15 and the lower cover 12 to form a second sealing cavity. The second sealing cavity and the first sealing cavity are communicated through a through hole 158 formed in the bottom shell 15.

[0269] The face cover 11 comprises a face cover side wall 113 and a face plate 111, the switch component 19 is located between the elastic buffer 27 and the control panel 13, is arranged at the middle portion of the control panel 13, and is pressed at any position of the face plate 111; the face plate 111 is moved to the direction of the bottom shell 15 at the pressed position, so that the elastic buffer 27 is deformed, the elastic buffer 27 abuts against and triggers the switch component 19, and the face cover is reset under the restoring force of the elastic buffer 27 after the external force disappears.

[0270] The bottom shell 15 comprises a bottom shell side wall 153 and a bottom plate 151, one of the bottom shell side wall 153 and the face cover side wall 113 is provided with a first clamping hook, and the other is provided with a first clamping groove matched with the shape of the first clamping hook; the height of the first clamping hook is less than the height of the first clamping groove, and the first clamping hook can move in the first clamping groove by not more than a set distance after the first clamping hook and the first clamping groove are clamped.

[0271] The second waterproof elastic element 14 cooperates with the lower cover 12 and the bottom shell 15 to form the second sealing cavity, and the related content is described in the foregoing embodiments, which will not be described herein.

[0272] The bottom shell inner plate 152 of the bottom shell 15 is provided with a through hole communicating the first sealing cavity and the second sealing cavity; the switch component 19 is located in the first sealing cavity between the face cover 11 and the control panel 13; and the side of the control panel 13 close to the bottom shell 15 is provided with a power supply mounting position, which is located in the second sealing cavity.

[0273] The elastic buffer in the embodiment can be a silica gel sleeve, and the second waterproof elastic element can be an elastic sealing ring.

[0274] Specifically, as shown in Figure 13 and Figure 14 , the signal transmitter of the present embodiment comprises a face cover 11, a control board 13, a bottom shell 15, a lower cover 12, and an elastic buffer 27 and a second waterproof elastic member 14. The face cover 11 comprises a face cover panel 111 and a face cover sidewall 113, the bottom shell 15 comprises a bottom shell bottom plate 151, a bottom shell sidewall 153 and a bottom shell inner wall 152, and the bottom shell sidewall 153 is located at the periphery of the bottom shell inner wall 152. The elastic buffer 27 is a sealing cover structure, and the second waterproof elastic member 14 is a sealing ring structure. The elastic buffer 27 cooperates with the face cover 11 and the bottom shell 15, and the second waterproof elastic member 14 cooperates with the lower cover 12 and the bottom shell 15, to form a sealed cavity. The control board 13 is located in the sealed cavity and is fixed to the bottom shell 15 in a similar manner as Figure 1 and Figure 2 . The side of the control board 13 away from the face cover 11 is provided with a power supply mounting position for containing a power supply 18, and the power supply 18 is used to supply power to the control board 13. The control board 13 is connected with a switch component 19.

[0275] The elastic buffer 27 comprises an elastic cover body 271 and a sealing outer edge 273 extending outward along the edge of the elastic cover body 271, and the elastic buffer 27 is sleeved on the bottom shell inner wall 152. The face cover panel 111 has a first protruding part 115, and in the state that the face cover 11 and the bottom shell 15 are clamped, the first protruding part 115 presses the sealing outer edge 273 against the bottom shell bottom plate 151 to form a sealing contact. Similarly as described above, in the state that the lower cover 12 and the bottom shell 15 are clamped, the lower cover 12 forms a sealing contact with the bottom shell 15 through the second waterproof elastic member 14. At this time, the elastic buffer 27, the bottom shell 15, the second waterproof elastic member 14 and the lower cover 12 together form a sealed cavity. The control board 13, the switch component 19 and the power supply 18 are all located in the sealed cavity to achieve the purpose of waterproofing.

[0276] As shown in Figure 14As shown, the control board 13 is located at the approximate center of the signal transmitter, the switch component 19 is located at the approximate center of the control board 13, and the elastic cover 271 is at least partially elastic, for example, the connecting section of the sealing cover and the sealing outer edge is made of elastic material, or the part of the sealing cover corresponding to the switch component 19 is made of elastic material. When the face cover panel 111 is pressed, the face cover panel 111 is displaced downward, the elastic cover 271 is correspondingly displaced downward, the face cover panel 111 presses the switch component 19 through the elastic cover 271, the switch component 19 is triggered, the key instruction generating circuit in the control board is turned on and generates a corresponding key instruction, and the signal generator further completes the transmission of the wireless control signal based on the key instruction. After the external force is removed, under the combined action of the elastic restoring force of the elastic cover 271 and the upward thrust generated by the reset of the switch component 19, the face cover panel 111 returns to the initial state, the switch component 19 is reset, and the key instruction generating circuit in the control board is turned off. Similarly, through the structure of the face cover 11 and the bottom shell 15, pressing any position of the face cover panel 111 can make the face cover panel 111 be displaced downward, and then trigger the switch component 19.

[0277] Similarly to the foregoing, the face cover panel 111 can be made of rigid material or elastic material. When the face cover panel 111 is made of elastic material, pressing the face cover panel 111 makes the face cover panel 111 elastically deform under the action of the external force, the elastic cover 271 is correspondingly displaced downward or deformed, the face cover panel 111 presses the switch component 19 through the elastic cover 271, and then triggers the switch component 19. After the external force is removed, under the combined action of the elastic restoring force of the face cover panel 111 and the elastic cover 271 and the upward thrust generated by the reset of the switch component 19, the face cover panel 111 returns to the initial state, the switch component 19 is reset, and the key instruction generating circuit in the control board is turned off.

[0278] In some embodiments, the face cover panel has a pushing arm (not shown in the figure), pressing the face cover panel makes the face cover panel be displaced downward, and the pushing arm presses the switch component through the sealing cover, so that the switch component is triggered.

[0279] In some embodiments, the sealing cap is an elastic cap made of an elastic material, such as a silicone cap or a rubber cap made of silicone or rubber. The sealing outer edge is an elastic outer edge made of an elastic material, such as a silicone outer edge or a rubber outer edge made of silicone or rubber. Furthermore, the sealing cap can also be a structure that includes both elastic and non-elastic caps, for example, a structure formed by combining a silicone or rubber cap with a plastic cap. The sealing outer edge can also be a structure that includes both elastic and non-elastic outer edges, for example, a structure formed by combining a silicone or rubber outer edge with a plastic outer edge. The specific design of the sealing cap can be diverse, as long as it achieves sealing contact and normal triggering of the switching component. It should be understood that the sealing outer edge is equivalent to the aforementioned sealing ring structure. The various contact methods that utilize sealing rings to achieve sealing can be similarly applied to the sealing outer edge structure to achieve sealing contact.

[0280] Specifically, for the elastic buffer 27, except Figure 14 Besides the sealing contact method shown, other sealing contact methods can also be used. For example, in some embodiments, the front cover panel has a protrusion, and the bottom shell panel has a groove structure formed by two protrusions (the protrusions may be independent protrusions formed on the panel, or they may include a sidewall structure such as a second bottom shell sidewall). The sealing outer edge is disposed in the groove structure, and the protrusion of the front cover panel abuts against the sealing outer edge to form a sealing contact. In some embodiments, the front cover panel has a protrusion, and the surface of the bottom shell panel has a groove. An elastic buffer is disposed in the groove, and the protrusion of the front cover panel abuts against the sealing outer edge to form a sealing contact. Similarly, the structures of the front cover panel and the bottom shell panel for forming the seal can be interchanged, with the same or similar effects, and will not be described in detail here.

[0281] In some embodiments, both the front cover panel and the bottom shell plate are provided with a first protrusion. The two first protrusions are arranged opposite each other. When the front cover and the bottom shell are engaged, the elastic outer edge abuts against the end faces of the two first protrusions to form a sealed contact.

[0282] In some embodiments, the faceplate has a protrusion, the bottom plate has a bottom plate protrusion, and an elastic outer edge is fitted around the bottom plate protrusion. When the faceplate and bottom plate are engaged, the protrusion of the faceplate presses the elastic outer edge against the bottom plate, forming a sealed contact. Similarly, in some embodiments, the bottom plate has a protrusion, the faceplate has a face plate protrusion, and the elastic outer edge structure is adaptively adjusted so that the elastic outer edge fits around the face plate protrusion. When the faceplate and bottom plate are engaged, the protrusion of the bottom plate presses the elastic outer edge against the faceplate, forming a sealed contact.

[0283] In some embodiments, the face cover panel is provided with a first protrusion, the bottom shell bottom plate is provided with two first protrusions, the first protrusion provided on the face cover panel is arranged opposite to one of the first protrusions provided on the bottom shell bottom plate, and the elastic outer edge is fixedly sleeved on the periphery of the other first protrusion of the bottom shell bottom plate, and the elastic outer edge abuts against the end surface of the two first protrusions arranged opposite to each other to form a sealed contact. Similarly, the two first protrusions of the bottom shell bottom plate are independent structures, or the two first protrusions of the bottom shell bottom plate together constitute different parts of a structure, for example, constitute a stepped structure. Similarly, the structure arrangement on the face cover and the bottom shell can be interchanged.

[0284] The elastic buffer and the bottom shell 15 surround 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 to achieve the purpose of waterproofing.

[0285] The combination and embodiments of other components, for example, the clamping and abutting mode of the lower cover and the bottom shell, the clamping mode of the face cover and the bottom shell, and the fixing mode of the control panel and the bottom shell, are described in detail in the embodiments shown in Figure 1 and Figure 2 and can be directly used herein, and will not be described again here.

[0286] The first sealing member of the embodiment adopts a sealing cover structure, which has better moisture-proof effect than the case of using a sealing ring and can realize more long-term stable sealing. Meanwhile, the lower cover is arranged, the lower cover is detachable, the power supply is exposed through the first bottom shell opening after the lower cover is removed, and the disassembly and installation of the power supply can be directly completed, and the battery replacement is more convenient.

[0287] Embodiment Eight

[0288] The signal transmitter provided by the embodiment eight of the application has the structure as shown in Figure 15 and 16 The signal transmitter is provided with a middle cover 16 and an elastic buffer 27 between the face cover 11 and the control panel 13; the elastic buffer 27 is located between the middle cover 16 and the switch component 19, the elastic buffer 27 cooperates with the middle cover 16 and the bottom shell 15 to form a first sealing cavity, and the control panel 13 is located in the first sealing cavity; under the action of an external force, the face cover 11 and the middle cover 16 move towards the bottom shell 15 to make the elastic buffer 27 deform, and the elastic buffer 27 triggers the switch component 19; after the external force disappears, the face cover 11 and the middle cover 16 reset under the restoring force generated by the elastic buffer 27.

[0289] The elastic buffer 27 comprises an elastic cover 271 and an elastic outer edge 273. The middle cover 16 is provided with a first protruding part 165, and the bottom shell is provided with a second protruding part 1511 abutting against the inner surface of the sidewall of the elastic cover 271. The first protruding part 165 presses the elastic outer edge 273 against the bottom plate of the bottom shell 15, forming a first sealed cavity. The middle cover is provided with a middle cover through hole 168, and the elastic buffer 27 is provided with a buffer protruding part 279 abutting against the face cover 11 through the middle cover through hole 168. The face cover 11 is provided with a pushing arm 112 abutting against the buffer protruding part 279.

[0290] The side of the control board 13 away from the bottom shell 15 is provided with a power supply mounting position for containing the power supply 18. The switch component 19 and the power supply mounting position are arranged on the same side of the control board 13.

[0291] Figure 15 and Figure 16 are respectively an exploded view and a cross-sectional structural schematic view of the signal transmitter of the embodiment. The signal transmitter adopts an elastic buffer for waterproofing and moisture-proofing, and is provided with a middle cover opening on a middle cover plate. Specifically, as shown in Figure 15 and Figure 16 , the signal transmitter comprises a middle cover 16, a control board 13, a bottom shell 15, an elastic buffer 27 and a face cover 11. The middle cover 16 comprises 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, for example a silica gel cover or a rubber cover, which comprises an elastic cover body 271 and an elastic outer edge 273 extending outward along the edge of the elastic cover body 271. The middle cover plate 161 is provided with a second protruding part 162, which presses the elastic outer edge 273 against the bottom plate 151 of the bottom shell in the state that the middle cover 16 is clamped with the bottom shell 15. At this time, the elastic cover and the bottom shell enclose 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 waterproofing.

[0292] The bottom plate 151 of the bottom shell is provided with a second protruding part 1511, and the elastic outer edge 273 is sleeved on the periphery of the second protruding part 1511, so as to fix the elastic buffer 27 and prevent the elastic buffer 27 from moving. The inner side of the second protruding part 1511 is further provided with a limiting part 1512, and the edge of the control board 13 is clamped with the limiting part 1512, so as to be fixed on the bottom plate 151 of the bottom shell. In addition, the control board 13 can also be fixed with the bottom plate 151 of the bottom shell through gluing or rivets and the like. It should be understood that the protruding part which simultaneously realizes the functions of limiting the elastic buffer and fixing the control board can also be applied to other embodiments of the present application. Moreover, Figure 16The sealing pressing mode shown is only an example, and other pressing sealing modes can also be used. Specifically, as described above, the elastic outer edge corresponds to the aforementioned elastic ring structure, and the same pressing mode as the aforementioned elastic ring structure can be used to achieve sealing contact. Since the related embodiments have been described in detail above, further description is omitted here.

[0293] The elastic cover 271 further includes an elastic panel 2712 and an elastic sidewall 2711 Figure 16 The elastic panel 2712 has a bumper protrusion 279. The bumper protrusion 279 extends into the middle cover opening 168, and the push arm 112 also extends into the middle cover opening 168. The push arm 112 abuts against the bumper protrusion 279, and the bumper protrusion 279 is not in contact with the switch component 19, but is separated from the switch component 19 by a certain distance. In some embodiments, the bumper protrusion 279 can also be in contact with the switch component 19. The control board 13 is located at approximately the center of the signal transmitter, and the switch component 19 is located at approximately the center of the control board 13. When the face cover panel 111 is pressed, the face cover panel 111 is displaced downward, the push arm 112 presses the switch component 19 through the elastic cover 271, the switch component 19 is triggered, the key instruction generating circuit in the control board 13 is turned on and generates a corresponding key instruction, and the signal generator further completes the transmission of a wireless control signal based on the key instruction. After the external force is removed, the face cover panel 111 returns to the initial state under the combined action of the elastic restoring force of the elastic cover 271 and the upward thrust generated by the reset of the switch component 19, the switch component 19 is reset, and the key instruction generating circuit in the control board is turned off. Similarly, through the structure of the clamping of the face cover 11 and the bottom shell 15, pressing any position of the face cover panel 111 can make the face cover panel 111 be displaced downward, and then trigger the switch component 19.

[0294] In fact, the elastic protrusion is not necessarily required, and the position relationship between the elastic protrusion and the push arm and the middle cover opening can be flexibly designed. For example, in some embodiments, the elastic protrusion passes through the middle cover opening, and at this time, the push arm can be flexibly selected to be retained or omitted. In some embodiments, the elastic protrusion is located below the middle cover opening, and the push arm passes through the middle cover opening. In some embodiments, the elastic panel is a substantially planar structure, and the push arm 112 passes through the middle cover opening 168. However, regardless of whether the elastic protrusion exists and how it is arranged, the elastic cover is in contact with the push arm, and under the action of the external force, the push arm triggers the switch component through the elastic cover. After the external force is removed, the elastic cover helps the face cover panel to return to the initial state under the action of the elastic restoring force.

[0295] Although Figure 15 and Figure 16The elastic buffer is a silica gel cover or a rubber cover, but in fact, as mentioned above, the elastic buffer is a sealing cover structure comprising a silica gel cover or a rubber cover, or a sealing cover structure comprising an elastic cover body and an elastic outer edge, for example, the elastic buffer can be a sealing cover comprising an elastic cover body and an elastic outer edge combined with a plastic structure.

[0296] The combination and implementation of other components, such as the snap mode of the middle cover and the face cover with the bottom shell, are the same as those of the previous embodiments, and can be directly used herein, and thus will not be described here again.

[0297] The face cover panel of the embodiment directly presses the switch component through the elastic cover body, which is more flexible in operation than the case of pressing through the middle cover, and since the face cover does not bear the functions related to waterproof, the material and structure design are more flexible, and the user can rework according to his own preferences.

[0298] Embodiment Nine

[0299] The signal transmitter provided by the embodiment nine of the present application has the structure as shown in Figure 17 and 18 In addition to the elastic buffer 27 and the middle cover 16, the signal transmitter is also provided with a lower cover 12 and a second waterproof elastic member 14; the second waterproof elastic member 14 cooperates with the bottom shell 15 and the lower cover 12 to form a second sealing cavity. The second sealing cavity and the first sealing cavity are communicated through the through hole formed on the bottom shell 15.

[0300] The face cover 11 comprises a face cover side wall 113 and a face panel 111, the switch component 19 is located between the elastic buffer 27 and the control panel 13, and is arranged at the middle part of the control panel 13. Pressing any position of the face panel 111, the position of the face panel 111 being pressed and the movement of the middle cover 16 towards the bottom shell can all make the elastic buffer 27 deform, abut and trigger the switch component 19 through the elastic buffer 27, and after the external force disappears, the face cover 11 and the middle cover 16 are reset under the restoring force generated by the elastic buffer 27.

[0301] The bottom shell 15 comprises a bottom shell sidewall 153 and a bottom shell plate 151. One of the bottom shell sidewall 153 and the cover sidewall 113 is provided with a first clamping hook, and the other is provided with a first clamping groove matched with the shape of the first clamping hook. The height of the first clamping hook is less than the height of the first clamping groove, and the first clamping hook can move in the first clamping groove by no more than a set distance after the first clamping hook and the first clamping groove are clamped. The middle cover 16 comprises a middle cover sidewall 163 and a middle cover plate 161. The bottom shell sidewall 153 is provided with a second clamping hook, and the middle cover sidewall 163 is provided with a third clamping hook. After the bottom shell 15 and the middle cover 16 are buckled, the second clamping hook and the third clamping hook cooperate to enable the middle cover 16 to move towards the bottom shell 15 by no more than a set distance. After the cover 11 and the bottom shell 15 are buckled and the middle cover 16 and the bottom shell 15 are buckled, the middle part of the face plate 111 is pressed, the cover 11 and the middle cover 16 can move towards the bottom shell 15 as a whole, so that the face plate 111 abuts against the elastic buffer 27, and the switch component is triggered through the elastic buffer 27; the face plate 111 is pressed at a position deviating from the center, and the side of the face plate 111 and the middle cover 16 pressed can pivot relative to the side away from the pressing position, so that the face plate 111 abuts against the elastic buffer, and the switch component is triggered through the elastic buffer 27.

[0302] The first sealing cavity and the second sealing cavity are related structures, which are described above, and will not be repeated here. In this embodiment, the elastic buffer is a silica gel sleeve, and the second waterproof elastic member is an elastic sealing ring.

[0303] Figure 17 And Figure 18 The signal transmitter of the present embodiment comprises a middle cover 16, a cover 11, a control plate 13, a bottom shell 15, a lower cover 12, an elastic buffer 27, and a second waterproof elastic member 14. The middle cover 16 comprises 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 cover 11 comprises a cover face plate 111 and a cover sidewall 113. The bottom shell 15 comprises a bottom shell plate 151, a bottom shell sidewall 153, and a bottom shell inner wall 152, and the bottom shell sidewall 153 is located at the periphery of the bottom shell inner wall 152. The elastic buffer 27 is a sealing cover structure, and the second waterproof elastic member 14 is a sealing ring structure. The elastic buffer 27 cooperates with the middle cover 16 and the bottom shell 15, and the second waterproof elastic member 14 cooperates with the lower cover 12 and the bottom shell 15, thereby forming a sealing cavity. The control plate 13 is located in the sealing cavity and is fixed to the bottom shell plate 151 by means of glue or rivets. The side of the control plate 13 away from the middle cover 16 is provided with a power supply mounting position for accommodating the power supply 18. The control plate 13 is connected with a switch component 19.

[0304] The elastic buffer 27 comprises an elastic cover 271 and a sealing rim 273 extending outwardly along the edge of the elastic cover 271. The bottom shell bottom plate 151 has a protrusion 1511, and the elastic buffer 27 is sleeved on the protrusion 1511. The middle cover plate 161 has a protruding portion 165, which presses the sealing rim 273 against the bottom shell bottom plate 151 to form a sealing contact in the state that the middle cover 16 and the bottom shell 15 are clamped. Similarly, in the state that the lower cover 12 and the bottom shell 15 are clamped, the lower cover 12 forms a sealing contact with the bottom shell 15 through the second waterproof elastic member 14. At this time, the elastic buffer 27, the bottom shell 15, the second waterproof elastic member 14, and the lower cover 12 together form a sealed cavity. The control board 13, the switch component 19, and the power supply 18 are all located in the sealed cavity to achieve the purpose of waterproofing.

[0305] The elastic cover 271 further comprises an elastic panel 2712 and an elastic side wall 2711. The elastic panel 2712 has a buffer protrusion 279, which further comprises a protruding panel 2791 and a protruding side wall 2792. The buffer protrusion 279 is at least partially elastic, for example, the protruding side wall 2792 is made of elastic material away from the protruding panel 2791, or the part of the protruding panel 2791 corresponding to the switch component 19 is made of elastic material.

[0306] As shown in Figure 18 The buffer protrusion 279 extends through the middle cover aperture 168. The control board 13 is located at the approximate center of the signal transmitter, and the switch component 19 is located at the approximate center of the control board 13. Pressing the face cover panel 111 causes the face cover panel 111 to displace downward and press the switch component 19 through the buffer protrusion 279, so that the switch component 19 is triggered, the key instruction generating circuit in the control board is turned on and generates a corresponding key instruction, and the signal generator further completes the transmission of the wireless control signal based on the key instruction. After the external force is removed, the face cover panel 111 returns to the initial state under the combined action of the elastic restoring force of the buffer protrusion 279 and the upward thrust generated by the reset of the switch component 19, and the switch component 19 is reset, and the key instruction generating circuit in the control board is disconnected. Similarly, through the clamping structure of the face cover 11 and the bottom shell 15, pressing any position of the face cover panel 111 can cause the face cover panel 111 to displace downward and further trigger the switch component 19.

[0307] Similar to the foregoing, the face cover panel 111 can be made of a rigid material or an elastic material. When the face cover panel 111 is made of an elastic material, the face cover panel 111 is pressed to produce elastic deformation under the action of an external force, the buffer protrusion 279 is correspondingly displaced downward or deformed, the face cover panel 111 presses the switch component 19 through the buffer protrusion 279, and the switch component 19 is triggered. After the external force is removed, under the combined action of the elastic restoring force of the face cover panel 111 and the buffer protrusion 279 and the upward thrust generated by the reset of the switch component 19, the face cover panel 111 returns to the initial state, the switch component 19 is reset, and the key instruction generating circuit in the control panel is disconnected.

[0308] In some embodiments, the face cover panel has a pushing arm (not shown in the figure), and when the face cover panel is pressed, the face cover panel is displaced downward, and the pushing arm presses the switch component through the sealing cover to trigger the switch component. In the case where the face cover panel has a pushing arm, the buffer protrusion does not have to pass through the middle cover opening, but can extend into the middle cover opening or be located below the middle cover opening, and correspondingly, the pushing arm extends into the middle cover opening or passes through the middle cover opening to effectively drive the switch component to trigger. Further, in the case where the face cover panel has a pushing arm, the buffer protrusion can be omitted, and the pushing arm can pass through the middle cover opening to effectively drive the switch component to trigger.

[0309] Embodiment Ten

[0310] The signal transmitter provided by the embodiment ten of the present application, as shown in Figure 19 and Figure 20 different from the foregoing embodiments, further comprises an inner cover 26, the middle cover 16 is provided with a middle cover through hole 164, the buffer elastic member 27 is provided with an elastic member through hole 278, and the inner cover 26 is matched with the middle cover through hole 164 and the elastic member through hole 278 to form a second accommodating cavity. The inner cover 26 comprises an inner cover side wall 263 and an inner cover plate 261, and the inner cover side wall 263 is provided with an inner cover clamping hook 265 matched with the middle cover 16 through hole to realize the clamping of the inner cover 26 and the middle cover 16.

[0311] 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 on the control panel to form a seal between the buffer elastic member 27 and the control panel 13. The second accommodating cavity is provided with a power supply mounting position.

[0312] Figure 19 and Figure 20These are exploded views and cross-sectional structural diagrams of the signal transmitter in this embodiment. The signal transmitter includes a middle cover 16, a control board 13, a bottom shell 15, an elastic buffer 27, a front cover 11, and an inner cover 26. The middle cover 16 includes a middle cover plate 161 and a middle cover sidewall 163. 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 cover 26 is disposed at the third middle cover through hole 164 and engages with the middle cover plate 161. The elastic buffer 27 is an elastic cover, which 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 element through hole 278 disposed in the elastic outer edge. The position and size of the elastic element through hole 278 correspond to the inner cover 26. The power supply mounting position on the control board 13 is located inside the elastic element through hole 278. Removing the inner cover 26 exposes the power supply 18, allowing for convenient disassembly, assembly, or replacement of the power supply.

[0313] like Figure 20 As shown, the control board 13 is located approximately at the center of the signal transmitter. The switch component 19 and the power supply 18 are mounted 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 shell 15 surround and form a sealed inner cavity. The control board 13, the switch component 19, and the power supply 18 are all located within this inner cavity. Furthermore, when the inner cover 26 is engaged with the middle cover 161, it presses the elastic outer edge 274 around the elastic through hole 278 against the control board 13. The inner cover 26 and the elastic buffer 27 form a sealed contact. The inner cover 26, the elastic outer edge 274, and the control board 13 form a sealed first receiving cavity for holding the power supply 18. The switch component 19 is located in a second receiving cavity outside the first receiving cavity of the inner cavity A1, corresponding to the position of the elastic cover 271. It can be seen that the switch component 19 is not located approximately at the center of the control board 13. This design helps to further reduce the size of the signal transmitter and achieve miniaturization of the signal transmitter. In some implementations, the switch component 19 may still be located approximately at the center of the control panel 13, which helps to control the signal transmitter.

[0314] Furthermore, such as Figure 20 As shown, the inner cover 26 includes an inner cover plate 261 and an inner cover sidewall 263. The inner cover sidewall 263 has an inner cover hook, and the inner cover 26 and the middle cover 16 are engaged by the inner cover hook. Of course, the inner cover 26 and the middle cover 16 can also be engaged by other structures. For example, in some embodiments, the inner cover sidewall 263 has a groove, and the inner cover 26 and the middle cover 16 are engaged by the groove.

[0315] The combination and implementation of other components, such as the snap mode of the middle cover and the face cover with the bottom shell, the specific structure of the elastic cover, the relationship of the elastic cover, the push arm and the switch component, the position relationship of the elastic protrusion and the middle cover opening, and the mode of the middle cover and the bottom shell sealingly abutting against the elastic cover, are the same as the related implementation in the foregoing embodiments, and thus are directly applicable here, and thus are not described here again.

[0316] The embodiment adds the inner cover to facilitate the disassembly of the power supply. For example, when replacing the battery, only the face cover and the inner cover need to be removed, without removing the middle cover and the elastic cover, and meanwhile, the exposure of the control board and the switch component is reduced, which helps the signal transmitter to achieve long-term stable work.

[0317] Similarly, other structures with the inner cover can also be used. For example, based on the signal transmitter structure with the middle cover in the foregoing embodiments, the middle cover opening is formed on the middle cover plate 161 at a position corresponding to the power supply mounting position of the control board 13, and the inner cover is arranged at the middle cover opening to be snap-fit with the middle cover plate 161 and to form a sealing contact. The specific snap mode of the inner cover with the middle cover plate 161 is described above, and thus is not described here again.

[0318] When the inner cover is arranged in the signal transmitter structure with the middle cover in the foregoing embodiments, it should be ensured that the inner cover forms a sealing contact with the middle cover in the state of being snap-fit with the middle cover, so that the middle cover, the inner cover, the sealing member and the bottom shell form a sealed inner cavity, and the control board, the switch component and the power supply are arranged in the inner cavity, to achieve the waterproof purpose.

[0319] For the implementation mode of sealing the middle cover and the bottom shell by using the first waterproof elastic member, the third waterproof elastic member is arranged between the inner cover and the middle cover plate to achieve the sealing contact of the inner cover with the middle cover. For the implementation mode of sealing the middle cover and the bottom shell by using the elastic buffer member, the middle cover opening is formed on the middle cover plate at a position corresponding to the power supply mounting position of the control board 13, and the inner cover is arranged at the middle cover opening to be snap-fit with the middle cover plate and to form a sealing contact by using the elastic buffer member.

[0320] In some embodiments, the third waterproof elastic member is an elastic ring, which can be a silica gel ring or a rubber ring composed of an elastic material such as silica gel or rubber. In the state of being snap-fit with the middle cover plate, the third waterproof elastic member abuts against the inner cover and the middle cover plate, and the specific implementation mode is described in the foregoing Figures 21-23 .

[0321] For example, as Figure 21As shown, when the inner cover and the middle cover are engaged, the third waterproof elastic member 24 is located between the inner cover side wall 263 and the side wall of the middle cover opening of the middle cover 161. The inner cover side wall 263 has a protrusion 268. The inner cover side wall 263, the protrusion 268 and the side wall of the middle cover opening of the middle cover 161 press against the third waterproof elastic member 24, causing the third waterproof elastic member 24 to undergo elastic deformation, thereby forming a sealed contact between the inner cover and the middle cover.

[0322] like Figure 22 As shown, the inner cover sidewall 263 has a protrusion 268, which engages with the middle cover plate 161. The inner cover plate 261 has an outer edge structure 262 extending outward relative to the inner cover sidewall 263. When the inner cover 26 and the middle cover plate 161 are engaged, the third waterproof elastic member 24 is positioned between the outer edge structure 262 and the middle cover plate 161. The outer edge structure 262 presses the third waterproof elastic member 24 against the middle cover plate 161, causing the third waterproof elastic member 24 to undergo elastic deformation, thereby forming a sealing contact between the inner cover and the middle cover plate. The outer edge structure 262 is provided with an outer edge protrusion 264, which, together with the inner cover sidewall 263, forms a groove structure to limit the third waterproof elastic member 24 and prevent it from moving. A reasonable design of the dimensions of the second sealing member and the groove structure, ensuring that the sealing member abuts against the side of the groove structure, helps to further improve the sealing effect.

[0323] like Figure 23 As shown, the inner cover plate 261 has an outer edge structure 262 extending outward relative to the inner cover sidewall 263. When the inner cover and the middle cover plate 11 are engaged, the third waterproof elastic member 24 is positioned between the outer edge structure 262 and the protrusion 268. The outer edge structure 262 and the protrusion 268 press against the third waterproof elastic member 24, causing it to undergo longitudinal elastic deformation. Simultaneously, the third waterproof elastic member 24 is also positioned between the inner cover sidewall 263 and the sidewall of the opening in the middle cover plate 11, causing it to undergo lateral elastic deformation. This multi-directional contact method helps improve the sealing effect of the sealing contact between the inner cover and the middle cover plate.

[0324] Similarly, other structures with inner covers can be used, such as omitting the front cover. Furthermore, in some embodiments, the middle cover has no openings other than the middle cover opening for installing the inner cover. The middle cover plate is provided with a push arm; when an external force is applied to the middle cover, the push arm moves under the action of the external force, pressing against the switch component through the elastic cover, thus triggering the switch component. In this case, the middle cover plate can be made of rigid material or elastic material, as its specific embodiments have been described in detail previously and will not be repeated here.

[0325] The inner cover structure described in this embodiment can be applied to various embodiments provided with a middle cover at the front, including the case of using an elastic buffer as a sealing element and the case of using a waterproof elastic element such as a sealing ring as a sealing element. When an elastic buffer is used as a sealing element, its structure is shown in the drawings of this embodiment Figure 19 and Figure 20 When a waterproof elastic element is used as a sealing element, a sealing ring can be arranged between the inner cover and the middle cover to achieve waterproofing therebetween. The structure and design form of the sealing ring refer to the relevant description of the sealing ring arranged between the middle cover and the bottom shell in the previous embodiments, which will not be described here.

[0326] Based on the same inventive concept, the embodiments of the present application also provide an electronic device comprising the signal transmitter described above.

[0327] Based on the same inventive concept, the embodiments of the present application also provide a signal transceiving system comprising a signal receiver and a signal transmitter, wherein the signal transmitter can be any of the signal transmitters provided in the embodiments described above.

[0328] The signal receiver is arranged in an electronic device to receive a control signal transmitted by the signal transmitter and control the electronic device to perform a corresponding operation based on the control signal.

[0329] The electronic device is an electronic doorbell, an alarm, a robotic vacuum cleaner, an electric curtain, a toilet, a lighting device, a water heater or a bath heater. As described in the related embodiments, one switch element is taken as an example. In actual applications, 2 to 4 switch elements can be arranged around the circuit board. Pressing any edge can trigger a specific one or two switch elements and emit a wireless radio frequency signal containing the signal.

[0330] The signal transmitter described above can be widely applied to electronic devices. The electronic devices receive the control signal transmitted by the signal transmitter through the signal receiver and can perform a set operation according to the received control signal. For example, in some embodiments, the electronic device is a doorbell or an alarm, which emits a corresponding prompt sound according to the received control signal. In some embodiments, the electronic device is a toilet, which performs a set flushing or other operation according to the received control signal. In addition, the electronic device can also be a robotic vacuum cleaner, an electric curtain, a lighting device, a water heater or a bath heater. That is, the signal transmitter of the present application has a simple, small and light structure, which is suitable for various wireless control scenes. Moreover, due to its excellent waterproof performance, it is especially suitable for electronic devices such as toilets, water heaters or bath heaters that are in a humid working environment.
