[0117] The beneficial effects of the above-described technical solutions provided in the embodiments of the present invention include at least the following:

[0118] The signal transmitter provided in this embodiment of the invention has a face cover and a bottom shell that, when fastened together, can move a short distance relative to each other when the face cover is pressed. The movement of the face cover presses against and triggers the switch component. After the external force disappears, the face cover can return to its original position. This method can achieve the triggering of a tactile switch with a simple structure. There are no requirements for the material of the face cover, and it does not need to have sufficient elastic deformation capacity to trigger the switch component. It is achieved through the relative movement of the face cover and the bottom shell. Based on the face cover, bottom shell, control board, and switch component, a signal transmitter module with complete functions is formed. It can independently realize signal transmission operation under the action of external force. Its overall structure is simple and compact, easy to operate, easy to disassemble and assemble, and convenient for users to replace or repair internal components.

[0119] The signal transmitter provided in this embodiment of the invention, through the cooperation of the front cover and the bottom shell, allows the switch component to be triggered by pressing any position on the front cover panel from all directions. When using it, the user does not need to pay special attention to the pressing position, making it convenient for the user.

[0120] The signal transmitter provided in this embodiment of the invention can be equipped with a first waterproof elastic element. The first waterproof elastic element cooperates with the front cover and the bottom shell to form a first sealed cavity, and electrical components such as the control board are placed in the sealed cavity to achieve waterproof and dustproof protection, meeting the usage requirements of humid or dusty environments. When the front cover is subjected to external force, the first waterproof elastic element can deform, which facilitates the movement of the front cover relative to the bottom shell. After the external force is removed, the first waterproof elastic element has a rebound force, which can reset the front cover.

[0121] The signal transmitter provided in this embodiment of the invention can be equipped with an elastic buffer. The elastic buffer is disposed between the face cover and the switch component, which can support the face cover and prevent the face cover from triggering the switch component when there is no external force. The elastic buffer, together with the face cover and the bottom shell, forms a first sealed cavity, which houses electrical components such as the control board, achieving waterproof and dustproof protection and meeting the needs of use in humid or dusty environments. When the face cover is subjected to external force, the elastic buffer can be deformed by the pressure of the face cover. The deformation of the elastic buffer triggers the switch component. After the external force disappears, the elastic buffer returns to its original shape, exhibiting a rebound force that allows the face cover to return to its original position.

[0122] The signal transmitter provided in this embodiment of the invention can also have a middle cover between the face cover and the control board and switch components. The detection switch is triggered by the middle cover. The middle cover can shield and protect the internal electronic components, facilitate the disassembly and assembly of the face cover, and prevent damage to the electronic components during the disassembly and assembly of the face cover.

[0123] The signal transmitter provided in this embodiment of the invention can also have a lower cover on the back of the signal transmitter. A second sealed cavity is formed between the lower cover and the bottom shell by a second waterproof elastic element. The second sealed cavity can be used to place electronic devices such as batteries. The batteries and other electronic devices can be easily replaced by opening the second sealed cavity.

[0124] The signal transmitter provided in this embodiment of the invention can also be provided with a second receiving cavity. The second receiving cavity is formed by the cooperation of an inner cover, an elastic buffer, a middle cover, etc., with openings on the upper part. The second receiving cavity can serve as a battery compartment, and the battery can be easily replaced by opening the inner cover of the second receiving cavity. The inner cover, elastic buffer, middle cover, etc., cooperate to achieve a sealed and waterproof effect.

[0159] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0160] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0161] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0162] To address the problems existing in the prior art, embodiments of the present invention provide a button, a switch assembly using the button, a related signal transmitter and a signal transmission system, etc., to meet the diverse usage requirements of the wireless controller, enabling the switch assembly to be triggered with a light touch of the button, and meeting one or more requirements such as waterproof performance, illumination, and convenient operation.

[0163] This invention provides a signal transmitter, including a face cover, a control board, and a bottom shell; the face cover and the bottom shell cooperate to form a receiving cavity; the control board is located in the receiving cavity and is connected to a switch component; under the action of an external force, the face cover can move no more than a set distance toward the bottom shell and trigger the switch component, and the control board sends a control signal after the switch component is triggered.

[0164] The aforementioned signal transmitter, after the front cover and bottom shell are fastened together, can move a short distance relative to each other when the front cover is pressed. The movement of the front cover presses against and triggers the switch component. After the external force is removed, the front cover can return to its original position. This method can achieve the triggering of a tactile switch with a simple structure. There are no requirements for the material of the front cover, and it does not need to have sufficient elastic deformation capacity to trigger the switch component. It is achieved through the relative movement of the front cover and bottom shell. Based on the front cover, bottom shell, control board, and switch component, a signal transmitter module with complete functions is formed. It can independently realize signal transmission operation under the action of external force. Its overall structure is simple and compact, easy to operate, easy to disassemble and assemble, and convenient for users to replace or repair internal components.

[0165] The following is a detailed description through specific embodiments.

[0166] Example 1

[0167] Embodiment 1 of the present invention provides a signal transmitter, the structure of which is as follows: Figure 1 and Figure 2 As shown, it includes: a face cover 11, a control plate 13, and a bottom shell 15; the face cover 11 and the bottom shell 15 cooperate to form a receiving cavity; the control plate 13 is located in the receiving cavity, and the control plate 13 is connected to a switch component 19; under the action of external force, the face cover 11 can move towards the bottom shell 15 by no more than a set distance and trigger the switch component, and the control plate 13 sends a control signal after the switch component 19 is triggered.

[0168] The cover 11 includes a cover sidewall 113 and a panel 111. The switch component 19 is located between the panel 111 and the control plate 13, and is disposed in the middle of the control plate 13. Pressing any position on the panel 111 will cause the pressed position to move towards the bottom shell 15, so that the middle of the panel 111 abuts against and triggers the switch component 19. After the cover 11 and the bottom shell 15 are fastened together, pressing the middle of the panel will allow the cover 11 to move as a whole towards the bottom shell 15, so that the panel abuts against and triggers the switch component. Pressing a position off-center from the panel will allow the pressed side of the panel to pivot relative to the side away from the pressed position, so that the panel abuts against and triggers the switch component.

[0169] The bottom shell 15 includes a bottom shell sidewall 153 and a bottom plate 151. One of the bottom shell sidewall 153 and the top cover sidewall 113 is provided with a first hook, and the other is provided with a first slot adapted to the shape of the first hook. The height of the first hook is less than the height of the first slot. After the first hook and the first slot are engaged, the first hook can move within the first slot by no more than a set distance.

[0170] A power supply mounting position is provided on the side of the control board 13 away from the bottom shell 15 for holding the power supply 18. The switch component 19 and the power supply mounting position are located on the same side of the control board 13.

[0171] The signal transmitter provided in this embodiment, after the front cover and bottom shell are fastened together, can move a short distance relative to each other when the front cover is pressed. This movement of the front cover presses against and triggers the switch component. After the external force disappears, the panel can return to its original position. This method achieves the triggering of a tactile switch with a simple structure, requiring no specific material for the front cover and no need for it to have sufficient elastic deformation capacity to trigger the switch component. The relative movement of the front cover and bottom shell is used to achieve this. Based on the front cover, bottom shell, control board, and switch component, a fully functional signal transmitter module is formed. It can independently perform signal transmission operations under external force. Its overall structure is simple, compact, easy to operate, and easy to disassemble and assemble, facilitating user replacement or repair of internal components. The cooperation between the front cover and bottom shell allows the switch component to be triggered by pressing any position on the front cover panel from any direction, eliminating the need for the user to focus on the pressing position, thus simplifying user operation.

[0172] The signal transmitter provided in this embodiment is Figure 1 and Figure 2 The signal transmitter shown is without a sealing ring. Except for the first waterproof elastic element and related structures, the other structures are the same as in Embodiment 2. The possible implementations of each related structure are described in Embodiment 2.

[0173] Example 2

[0174] Embodiment 2 of the present invention provides a signal transmitter, such as Figure 1 and Figure 2 As shown, the difference between this and the signal transmitter provided in Embodiment 1 is that a first waterproof elastic element 17 is provided between the face cover 11 and the bottom shell 15, so that the face cover 11 and the bottom shell 15 can be waterproof and moisture-proof after they are fastened together. Its overall structure is as follows: Figure 1 As shown.

[0175] The signal transmitter consists of a faceplate 11, a control board 13, a bottom shell 15, and a first waterproof elastic element 17. The faceplate 11 and the bottom shell 15 cooperate to form a receiving cavity. The first waterproof elastic element 17 cooperates with the faceplate 11 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 faceplate 11 moves towards the bottom shell 15, causing the first waterproof elastic element 17 to deform. After the external force disappears, the faceplate 11 returns to its original position under the restoring force generated by the first waterproof elastic element 17.

[0176] A first protrusion 115 is provided on at least one of the cover 11 and the bottom shell 15. When the cover and the bottom shell are fastened together, the first protrusion 115 presses against the first waterproof elastic member 17 to form a first sealing cavity.

[0177] like Figure 2As shown, one optional configuration is that one of the face cover 11 and the bottom shell 15 is provided with a first protrusion 115, and the other is provided with a first mounting groove 157. The first waterproof elastic member 17 is placed in the first mounting groove 157. When the face cover 11 and the bottom shell 15 are fastened together, the first protrusion 115 presses against the first waterproof elastic member 17 to form a first sealing cavity.

[0178] like Figure 3 As shown, another optional configuration is that both the face cover 11 and the bottom shell 15 are provided with a first protrusion 115. When the face cover 11 and the bottom shell 15 are fastened together, the first protrusion 115 on the face cover 11 and the first protrusion 115 on the bottom shell 15 press against the first waterproof elastic member 17 to form a first sealing cavity. Specifically, the face cover 11 includes a face cover sidewall 113 and a panel 111, and the bottom shell 15 includes a bottom shell sidewall 153 and a bottom plate 151. The first protrusion 115 is provided on the panel 111 and / or the bottom plate 151.

[0179] A power supply mounting position is provided on the side of the control board 13 away from the bottom shell 15 for holding the power supply 18. The switch component 19 and the power supply mounting position are located on the same side of the control board 13.

[0180] The signal transmitters provided in Embodiments 1 and 2 above do not include the first waterproof elastic element in Embodiment 2. (Refer to...) Figure 1 and Figure 2 As shown, the signal transmitter of Embodiment 2 of the present invention includes a face cover 11, a control plate 13, a bottom shell 15, and a first waterproof elastic element 17. The face cover 11 includes a face panel 111 and a face cover sidewall 113. The bottom shell 15 includes a bottom plate 151 and a bottom shell sidewall 153. The face cover 11 and the bottom shell 15 are engaged by the face cover sidewall 113 and the bottom shell sidewall 153 to form a receiving cavity A. The first waterproof elastic element 17 is an elastic element, which is an elastic ring structure made of elastic material. In some embodiments, the first waterproof elastic element 17 is a silicone ring or rubber ring made of silicone or rubber. A first protrusion 115 is provided on the face panel 111. When the face cover 11 and the bottom shell 15 are engaged, the first protrusion 115 presses the first waterproof elastic element 17 against the bottom plate 151, dividing the receiving cavity A into a sealed inner cavity A1 and an outer cavity A2. The control board 13 is fixed to the base shell 15, and the switch component 19 is located approximately at the center of the control board 13 and connected to it. The control board 13 also has a power supply mounting position for housing a power supply 18, which supplies power to the control board 13. That is, the switch component 19 and the power supply 18 are both located between the control board 13 and the panel 111, and the control board 13, switch component 19, and power supply 18 are all located within the inner cavity A1 for waterproofing purposes. In some embodiments, the power supply 8 is a battery, such as a lithium battery or a solar panel.

[0181] like Figure 2 As shown, the base plate 151 has a first mounting groove 157 formed by two protrusions. A first waterproof elastic member 17 is disposed in the first mounting groove 157. The protrusions 115 press against the first waterproof elastic member 17, causing the first waterproof elastic member 17 to undergo elastic deformation, thereby forming a good sealing contact. The groove structure can effectively fix the first waterproof elastic member 17, which helps to form a good sealing contact. In some embodiments, the groove structure is a groove on the surface of the bottom plate of the bottom shell (not shown in the figure). Reasonably designing the dimensions of the seal and the groove structure so that the seal abuts against the side of the groove structure helps to further improve the sealing effect. That is, in the case where the protrusion forms a groove structure, the seal abuts against the side of the protrusion on both sides to obtain a better sealing effect; in the case where the groove forms a groove structure, the seal abuts against the side of the groove to obtain a better sealing effect. Of course, the groove structure can also be omitted, and sealing can be achieved simply by the protrusion of the faceplate pressing against the seal.

[0182] It should be understood that the sealing structures of the faceplate and the bottom plate are interchangeable, with similar or identical effects. Specifically, the bottom plate has a protrusion that, when the faceplate and bottom plate are engaged, presses the seal against the faceplate, dividing the cavity into a sealed inner and outer cavity. Similarly, in some embodiments, the faceplate has a groove structure formed by two protrusions, in which the seal is disposed. The protrusion of the bottom plate presses against the seal, causing elastic deformation of the seal and thus forming a good sealing contact. In some embodiments, the groove structure is a recess on the surface of the faceplate. Similarly, properly designing the dimensions of the seal and the groove structure so that the seal abuts against the side of the groove structure helps to further improve the sealing effect. Of course, the groove structure can also be omitted, and sealing can be achieved solely by the protrusion of the bottom plate pressing against the seal.

[0183] In addition, the faceplate and the bottom plate can also use other structures to form a sealed contact. In some embodiments, such as Figure 3 As shown, the faceplate has a first protrusion 115a, and the bottom plate also has a first protrusion 115b. The two first protrusions are positioned opposite each other. When the faceplate and bottom plate are engaged, the first waterproof elastic member 17 abuts against the end faces of the first and second protrusions, forming a sealed contact. In some embodiments, such as... 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, due to 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 pressed position as a fulcrum, the first engagement portion near the pressed side moves downwards relative to the second engagement portion, and the panel 111 presses against the switch component 19 to trigger it.

[0191] When the sidewall of the cover is located inside the sidewall of the bottom shell, the cover may further include an outer sidewall disposed around the sidewall of the cover and a cover panel extension (not shown in the figure) between the outer sidewall and the sidewall of the cover. The outer sidewall surrounds the sidewall of the bottom shell and the sidewall of the cover, and together with the cover panel extension, effectively conceals the structure of the bottom shell sidewall and the sidewall of the cover engaging, thereby improving the overall visual effect of the product.

[0192] like Figure 2 As shown, the control board 13 is located approximately at the center of the signal transmitter, and the switch component 19 is located approximately at the center of the control board 13. The control board 13 is equipped with a signal generator and a key command generation circuit. The panel 111 is a rigid structure. Pressing the panel 111 causes the first waterproof elastic element 17 to elastically deform, resulting in a downward displacement of the panel 111, which presses against the switch component 19, triggering the switch component 19. This activates the key command generation circuit in the control board 13 and generates a corresponding key command. The signal generator then uses this key command to further transmit the wireless control signal. After the external force is removed, under the combined action of the elastic restoring force of the first waterproof elastic element 17 and the upward thrust generated by the reset of the switch component 19, the panel 111 and the first waterproof elastic element 17 return to their initial state, the switch component 19 resets, and the key command generation circuit in the control board 13 disconnects. It should be understood that the triggered state of the switch component 19 corresponds to the state where the key command generation circuit is on, and the reset state of the switch component 19 corresponds to the state where the key command generation circuit is off.

[0193] In some embodiments, the first waterproof elastic element 17 is an elastic element whose main function is to provide movement space for the panel 111 through elastic deformation, allowing the panel 111 to move downward under the action of external force to trigger the switch component 19. On the other hand, it provides elastic restoring force for the panel 111 to reset after the external force is removed. In addition, the first waterproof elastic element 17 can also perform the waterproof sealing function as described above.

[0194] It should be understood that triggering the switch component specifically means that the switch component starts to work. When the switch component is triggered, the corresponding circuit is connected, that is, the key command generation circuit in the control board is connected and generates the corresponding key command; correspondingly, when the switch component is not triggered, the corresponding circuit is in the off state.

[0195] In some embodiments, the control board 13 is a printed circuit board (PCB). At least a portion of the panel 111 is elastic, capable of elastic deformation under external force. Pressing the panel 111 causes this elastic deformation, thereby triggering the switch component 19. In this case, when the panel 111 is pressed, in addition to the elastic deformation of the panel 111, the first waterproof elastic element 17 may also undergo elastic deformation as described above. Correspondingly, when the external force is removed, the force that restores the panel 111 to its initial state may come not only from its own elastic restoring force but also from the elastic restoring force of the aforementioned first waterproof elastic element 17 and the upward thrust generated by the reset of the switch component 19.

[0196] The signal transmitter in this embodiment can be equipped with a first waterproof elastic element. This first waterproof elastic element, in conjunction with the faceplate and bottom shell, forms a first sealed cavity. Electrical components such as the control board are placed within this sealed cavity, achieving waterproofing and dustproofing to meet the needs of humid or dusty environments. When the faceplate is subjected to external force, the first waterproof elastic element deforms, facilitating movement of the faceplate relative to the bottom shell. After the external force disappears, the first waterproof elastic element has a rebound force, allowing the faceplate to return to its original position. The faceplate directly engages with the bottom shell, forming a fully pressable structure with the support of the switch component, resulting in a simple structure. Simultaneously, the elastic deformation characteristics of the first waterproof elastic element are fully utilized, effectively supporting the faceplate panel on one hand, and allowing the faceplate panel to undergo downward displacement under external force through the elastic deformation of the sealing element, triggering the switch component. Furthermore, the structure of the sealing element, faceplate, and bottom shell can be rationally designed to form a sealed cavity, achieving waterproofing. In this case, the faceplate panel serves both as an operating panel and, in conjunction with the bottom shell and sealing element, forms a sealed waterproof structure. The overall structure is simple, compact, and lightweight.

[0197] Example 3

[0198] The signal transmitter provided in Embodiment 3 of the present invention has the following structure: Figure 7 and Figure 8 As shown, the difference from the signal transmitter provided in Embodiment 2 is that it also includes 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 sealed cavity.

[0199] The second sealing cavity and the first sealing cavity can be interconnected or set independently. When interconnected, the second sealing cavity and the first sealing cavity are connected through a through hole 158 on the bottom shell 15. The second sealing cavity can be used to house electronic devices such as batteries, and the electronic devices can be easily replaced by opening the second sealing cavity independently.

[0200] In some optional embodiments, the cover 11 includes a cover sidewall 113 and a panel 111. The switch component 19 is located between the panel 111 and the control plate 13, and is disposed in the middle of the control plate 13. Pressing any position of the panel 111 and moving the pressed position of the panel 111 toward the bottom shell 15 can cause the first waterproof elastic member 17 to deform. The middle part of the panel 111 abuts against and triggers the switch component 19. After the external force disappears, the cover 11 is reset under the action of the restoring force generated by the first waterproof elastic member 17.

[0201] The faceplate 11 and the bottom shell 15 can be fastened together using various locking structures. In one embodiment, the bottom shell 15 includes a bottom shell sidewall 153 and a bottom plate 151. One of the bottom shell sidewall 153 and the faceplate sidewall 113 is provided with a first hook 117, and the other is provided with a first slot 155 adapted to the shape of the first hook. The height of the first hook 117 is less than the height of the first slot 155. After the first hook 117 and the first slot 155 are engaged, the first hook 117 can move within the first slot 155 by no more than a set distance. After the faceplate 11 and the bottom shell 15 are fastened together, pressing the center of the panel 111 allows the faceplate 11 to move as a whole toward the bottom shell 15, causing the panel 111 to abut against and trigger the switch component 19. Pressing the panel 111 off-center allows the pressed side of the panel 111 to pivot relative to the side away from the pressed position, causing the panel 111 to abut against and trigger the switch component 19.

[0202] There are various possible installation relationships between the second waterproof elastic element 14, the lower cover 12, and the bottom shell 15.

[0203] One possible implementation is that the lower cover 12 includes a lower cover side wall 123 and a back plate 121, and the bottom shell 15 also includes a bottom shell inner wall 152 and a bottom shell inner plate 156; the lower cover side wall 123 is provided with a second mounting groove, the second waterproof elastic member 14 is placed in the second mounting groove, and the bottom shell inner wall 152 abuts against and presses the second waterproof elastic member to form a second sealing cavity.

[0204] One possible implementation is that the lower cover 12 includes a lower cover side wall 123 and a back plate 121, and the bottom shell 15 also includes a bottom shell inner wall 152 and a bottom shell inner plate 156; the bottom shell inner wall 152 is provided with a second mounting groove, the second waterproof elastic member 14 is placed in the second mounting groove 122, and the lower cover side wall 123 abuts against and presses the second waterproof elastic member to form a second sealing cavity.

[0205] One possible implementation is that the lower cover 12 includes a lower cover sidewall 123 and a back plate 121, and the bottom shell also includes a bottom shell inner wall 152 and a bottom shell inner plate 156; the bottom shell inner wall 152 and the lower cover sidewall 123 respectively abut against both sides of the second waterproof elastic member 14, pressing the second waterproof elastic member 14 to form a second sealing cavity.

[0206] The bottom shell 15 has an inner plate 156 on its bottom shell, which has a bottom shell through hole 158 connecting 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; a power supply mounting position is provided on the side of the control plate 13 near the bottom shell 15, and the power supply mounting position is located in the second sealing cavity.

[0207] Optionally, both the first waterproof elastic element 17 and the second waterproof elastic element 14 can be elastic sealing rings.

[0208] Reference Figure 7 and Figure 8 As shown, the signal transmitter of Embodiment 3 of the present invention includes a faceplate 11, a control board 13, a bottom shell 15, a lower cover 12, a first waterproof elastic element 17, and a second waterproof elastic element 14. The faceplate 11 includes a faceplate panel 111 and a faceplate sidewall 113. The bottom shell 15 includes a bottom shell base plate 151, a bottom shell sidewall 153, and a bottom shell inner wall 152, with the bottom shell sidewall 153 located around the bottom shell inner wall 152. Both the first waterproof elastic element 17 and the second waterproof elastic element 14 are sealing ring structures. The first waterproof elastic element 17 cooperates with the faceplate 11 and the bottom shell 15, and the second waterproof elastic element 14 cooperates with the lower cover 12 and the bottom shell 15 to form a sealed cavity. The control board 13 is located within the sealed cavity. A power supply mounting position is provided on the side of the control board 13 away from the faceplate 11 for holding a power supply 18, which supplies power to the control board 13. The control board 13 is connected to a switch component 19. Under the action of external force, the switch component 19 is triggered by the face cover 11 pressing against it.

[0209] In some embodiments, the first waterproof elastic element 17 and the second waterproof elastic element 14 are elastic elements, specifically elastic ring structures made of elastic materials, such as silicone rings or rubber rings made of silicone or rubber. In some embodiments, the power source 18 is a battery, such as a lithium battery or a button cell battery.

[0210] Specifically, the bottom plate 151 of the bottom shell has a bottom shell through hole 158, and the inner wall 152 of the bottom shell is located at the bottom shell through hole 158. An inner plate 156 of the bottom shell is formed on the inner side of the inner wall 152. The control plate 13 is disposed on the inner plate 156 of the bottom shell, and the edge of the control plate 13 engages with the limiting part of the inner wall 152 of the bottom shell, thereby fixing the control plate 13 to the inner plate 156 of the bottom shell. At this time, the inner wall 152 of the bottom shell simultaneously has the functions of limiting the first waterproof elastic member 17 and fixing the control plate. It should be understood that the control plate 13 can also be fixed to the bottom shell 15 by other means, such as adhesive or rivets.

[0211] The power supply mounting position of the control board 13 is located at a position corresponding to the through hole 158 of the bottom shell, and is used to hold the power supply. The side wall 113 of the face cover is located outside the side wall 153 of the bottom shell. The side wall 113 of the face cover has a first hook 117, which is a protrusion formed on the inner side of the side wall 113 of the face cover. The side wall 153 of the bottom shell has a first groove 155, which is a groove formed on the outer side of the side wall 153 of the bottom shell. The face cover 11 and the bottom shell 15 are engaged by the first groove 155. A raised bottom shell 154 is also formed on the bottom shell base plate 151. The raised bottom shell 154 and the inner wall 152 of the bottom shell form a groove structure. The first waterproof elastic element 17 is disposed in the groove structure. The face cover panel 111 is provided with a first protrusion 115. When the face cover 11 and the bottom shell 15 are engaged, the first protrusion 115 presses the first waterproof elastic element 17 against the bottom shell base plate 151, causing the first waterproof elastic element 17 to undergo elastic deformation, thereby forming a good sealing contact.

[0212] The lower cover 12 includes a back plate 121 and a lower cover sidewall 123. The back plate 121 includes a first portion 127 located inside the lower cover sidewall 123 and a second portion 129 located outside the lower cover sidewall 123. A fourth hook 125 is also provided in the second portion 129. A fourth slot 159 is provided on the bottom shell sidewall 153. The fourth hook 125 passes through an opening on the bottom shell and cooperates with the fourth slot 159 to lock the lower cover and the bottom shell together. The fourth slot 159 can also be designed as a hole structure. Alternatively, the bottom shell sidewall and the lower cover can be fixed by other structures.

[0213] The second waterproof elastic element 14 is located between the lower cover side wall 123 and the bottom shell inner wall 152. The lower cover side wall 123 has a groove structure to accommodate the second waterproof elastic element 14. When the lower cover 12 and the bottom shell 15 are engaged, the second waterproof elastic element 14 abuts against the groove structure of the lower cover side wall 123 and the side of the bottom shell inner wall 152 to form a sealed contact. Alternatively, the groove structure to accommodate the second waterproof elastic element 14 can also be provided on the bottom shell inner wall 152, or both the lower cover side wall 123 and the bottom shell inner wall 152 can have groove structures to accommodate the second waterproof elastic element 14. Furthermore, the groove structure is not necessary and can be omitted or replaced by other structures.

[0214] like Figure 8As shown, the face cover 11, the first waterproof elastic element 17, the bottom shell 15, the second waterproof elastic element 14, and the lower cover 12 together form a sealed cavity. The control board 13 is fixed on the bottom shell 15 and is located approximately at the center of the signal transmitter. The switch component 19 is connected to the control board 13 and is located approximately at the center of the control board 13. The battery 113 and the switch component 19 are respectively disposed on both sides of the control board 13. Pressing any position on the face cover panel 111 will cause the face cover panel 111 to move downward, thereby triggering the switch component 19. For example, when pressing the approximately center position of the face cover panel 111, the first hook 117 moves downward relative to the first slot 155, and the face cover panel 111 presses against the switch component 19 to trigger it. When the edge of the faceplate 111 is pressed, the faceplate 111 rotates around the locking structure on the opposite side of the pressing position as a fulcrum. The first hook 117 near the pressing side moves down relative to the first slot 155, and the faceplate 111 presses against the switch component 19 to trigger it.

[0215] In this embodiment, the front cover serves as both an operating panel and a sealed, waterproof structure when combined with the bottom shell. The bottom cover is detachable; by removing the bottom cover, the power supply is exposed through the opening in the first bottom shell, allowing for direct disassembly and installation of the power supply, which is very convenient. Moreover, the overall structure is simple, compact, and lightweight.

[0216] The difference between this embodiment and Embodiment 2 lies in the arrangement of the lower cover and the second waterproof elastic element, as well as their installation relationship with related components. The engaging and sealing structures can also be configured in various different forms. For details, please refer to the description of the installation relationship and related structures of the first waterproof elastic element with the bottom shell, panel, and other related components in Embodiment 2; these will not be repeated here. Other structures in this embodiment, which have already been described in Embodiment 2, will not be described in detail again.

[0217] Example 4

[0218] The signal transmitter provided in Embodiment 4 of the present invention has the following structure: Figure 9 and Figure 10 As shown, the difference between this and the signal transmitter provided in Embodiment 2 is that it also includes a middle cover 16 disposed between the front cover 11 and the control board 13. Under external force, the front cover 11 and the middle cover 16 can move towards the bottom shell by no more than a set distance, triggering the switch component 19 through the middle cover 16. The middle cover, disposed between the front cover and the control board / switch component, triggers the detection switch. The middle cover can shield and protect the internal electronic components, facilitate the removal and installation of the front cover, and prevent damage to the electronic components during the removal and installation process.

[0219] A push arm 112 is provided in the middle of the face cover 16, which abuts against the middle cover 16. The middle cover plate 161 of the middle cover 16 contains elastic material. When any position of the panel 111 on the face cover 11 is pressed, the push arm 112 moves, causing the middle cover plate 161 to undergo elastic deformation, pressing against and triggering the switch component 19.

[0220] The face cover 11 includes a face cover sidewall 113 and a panel 111. The bottom shell includes a bottom shell sidewall 153 and a bottom plate 151. One of the bottom shell sidewall 153 and the face cover sidewall 113 is provided with a first hook 117, and the other is provided with a first slot 155 adapted to the shape of the first hook. The height of the first hook is less than the height of the first slot. After the first hook and the first slot are engaged, the first hook can move within the first slot by no more than a set distance.

[0221] The middle cover 16 includes a middle cover sidewall 163 and a middle cover plate 161. A second hook 1510 is provided on the bottom shell sidewall, and a third hook 167 is provided on the middle cover sidewall. After the bottom shell 15 and the middle cover 16 are fastened together, the second hook 1510 and the third hook 167 cooperate to allow the middle cover to move toward the bottom shell direction without exceeding a set distance.

[0222] The mounting and engaging structures between the face cover 11 and the bottom shell 15, and between the bottom shell 15 and the middle cover 16, can also be designed in various ways, and can be referred to the relevant descriptions in the previous embodiments.

[0223] After the front cover 11 and the bottom shell 15 are fastened together, and the middle cover 16 and the bottom shell 15 are fastened together, pressing the middle part of the panel 111 will allow the front cover 11 to move as a whole toward the bottom shell, so that the panel 111 abuts against the middle cover 16, triggering the switch component 19 through the middle cover 16; pressing the panel 111 to a position off-center will allow the pressed side of the panel 111 to pivot relative to the side away from the pressed position, so that the panel 111 abuts against the middle cover, triggering the switch component through the middle cover 16.

[0224] In this embodiment, the signal transmitter, in addition to the middle cover 16, also includes a first waterproof elastic element 17. The first waterproof elastic element 17, together with the middle cover 16 and the bottom shell 15, forms a first sealed cavity, and the control plate 13 is located inside the first sealed cavity. Under the action of external force, the face cover 11 and the middle cover 16 move toward the bottom shell 15, causing the first waterproof elastic element 17 to deform. After the external force disappears, the face cover 11 and the middle cover 16 return to their original position under the restoring force generated by the first waterproof elastic element 17.

[0225] The cover includes a side wall and a panel. The switch component 19 is located between the panel 111 and the control plate 13, and is set in the middle of the control plate 3. Pressing any position of the panel 111 will cause the first waterproof elastic element 17 to deform as the pressed position moves towards the bottom shell 15. The middle part of the panel 111 abuts against the middle cover 16, and the switch component is triggered through the middle cover 16. After the external force disappears, the cover 11 and the middle cover 16 are reset under the restoring force generated by the first waterproof elastic element 17.

[0226] In this embodiment, after the middle cover 16 is provided, the first waterproof elastic element 17 cooperates with the middle cover 16 and the bottom shell 15 to form a seal, but no longer cooperates with the top cover 11 to form a seal. In this way, removing the top cover does not affect the waterproof effect, and it is convenient to replace different top covers and design patterns for the top cover without considering the waterproof function.

[0227] The middle cover 16 and the bottom shell 15 can be engaged with the first waterproof elastic member 17 in various ways. A first protrusion 115 can be provided on at least one of the middle cover 16 and the bottom shell 15. When the middle cover and the bottom shell are engaged, the first protrusion presses against the first waterproof elastic member to form a first sealing cavity. The middle cover 16 includes a middle cover sidewall 163 and a middle cover plate 161, and the bottom shell 15 includes a bottom shell sidewall 153 and a bottom plate 151. The first protrusion 165 is provided on the middle cover plate 161 and / or the bottom plate 151.

[0228] One possible implementation is that one of the middle cover 16 and the bottom shell 15 is provided with a first protrusion 165, and the other is provided with a first mounting groove. The first waterproof elastic member 17 is placed in the first mounting groove. When the middle cover 16 and the bottom shell 15 are fastened together, the first protrusion 165 presses the first waterproof elastic member 17 to form a first sealing cavity.

[0229] One possible implementation is that both the middle cover 16 and the bottom shell 15 are provided with a first protrusion 165. When the middle cover 16 and the bottom shell 15 are fastened together, the first protrusion on the middle cover 16 and the first protrusion on the bottom shell 15 press against the first waterproof elastic member 17 to form a first sealing cavity.

[0230] A power supply mounting position is provided on the side of the control board 13 away from the bottom shell 15 for holding the power supply. The switch component 19 and the power supply mounting position are located on the same side of the control board 13.

[0231] See Figure 9 and Figure 10 The diagram shows an exploded view and a cross-sectional structural schematic of the signal transmitter. Figure 1 and Figure 2 The structures shown are different, Figure 9 and Figure 10 The signal transmitter shown also includes a top cover positioned above the top cover.

[0232] Specifically, such as Figure 9 and Figure 10 As shown, the signal transmitter includes a middle cover 16, a control plate 13, a bottom shell 15, a first waterproof elastic element 17, and a face cover 11. The middle cover 16 includes a middle cover plate 161 and a middle cover side wall 163, and the bottom shell 15 includes a bottom shell base plate 151 and a bottom shell side wall 153. The face cover 11 includes a face cover panel 111, a face cover side wall 113, and a push arm 112. The middle cover 16 and the bottom shell 15 are engaged by the middle cover side wall 163 and the bottom shell side wall 153 to form a receiving cavity A. A first protrusion 165 is provided on the middle cover plate 161. When the middle cover 16 and the bottom shell 15 are engaged, the first protrusion 165 presses the first waterproof elastic element 17 against the bottom shell base plate 151, dividing the receiving cavity A into a sealed inner cavity A1 and an outer cavity A2.

[0233] like Figure 10 As shown, the bottom plate 151 of the bottom shell has a groove structure formed by two protrusions. The first waterproof elastic element 17 is disposed in this groove structure. The first protrusion 165 presses against the first waterproof elastic element 17, causing the sealing element to undergo elastic deformation, thereby forming a good sealing contact. Figure 1 and Figure 2 Similarly, in the illustrated embodiment, the first waterproof elastic element 17 can be sealed to the top cover panel and the bottom shell panel in various ways, i.e. Figure 1 and Figure 2 The contact method and its variant implementation methods shown in Figure 9 and Figure 10 The structure shown still applies, and will not be elaborated further here.

[0234] like Figure 10 As shown, the middle cover sidewall 163 has a third hook 167, and the bottom shell sidewall 153 has a second hook 1510. The third hook 167 and the second hook 1510 engage to form a receiving cavity A. The top cover sidewall 113 has a first hook 117, and the bottom shell sidewall 153 also has a first groove 155. The first hook 117 and the first groove 155 engage.

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

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

[0237] like Figure 10As shown, the control board 13 is located approximately at the center of the signal transmitter, and the switch component 19 is located approximately at the center of the control board 13. Both the front cover panel 111 and the middle cover panel 161 are rigid structures. Pressing the front cover panel 111 causes it to press against the middle cover panel 161 via the push arm 112. The first waterproof elastic element 17 undergoes elastic deformation, causing both the front cover panel 111 and the middle cover panel 161 to displace downwards, pressing against the switch component 19 and triggering it. This activates the button command generation circuit in the control board, generating a corresponding button command. The signal generator then uses this button command to further transmit the wireless control signal. After the external force is removed, under the combined action of the elastic restoring force of the first waterproof elastic element 17 and the upward thrust generated by the reset of the switch component 109, the middle cover panel 161, the first waterproof elastic element 17, and the front cover panel 111 return to their initial state. The switch component 19 resets, and the button command generation circuit in the control board is disconnected.

[0238] Similarly, the first waterproof elastic element 17 is an elastic element whose main function is to provide movement space for the front cover panel 111 and the middle cover plate 161 through elastic deformation, allowing them to move downward under external force to trigger the switch component 19. On the other hand, it provides elastic restoring force for the front cover panel 111 and the middle cover plate 161 to return to their original position after the external force is removed. In addition, the first waterproof elastic element 17 can also perform the waterproof sealing function as described above.

[0239] In some embodiments, the middle cover plate 161 is elastic in at least a portion of its area, capable of elastic deformation under external force. In this case, pressing the front cover plate 111 causes the middle cover plate 161 to elastically deform under the action of the push arm 112, thereby triggering the switch component 19. In this case, when the front cover plate 111 is pressed, in addition to the elastic deformation of the middle cover plate 161, the first waterproof elastic element 17 may also elastically deform as described above. Correspondingly, when the external force is removed, the force that restores the front cover plate 111 to its initial state may 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 element 17 and the upward thrust generated by the reset of the switch component 19.

[0240] By means of the engaging structure between the faceplate 11 and the bottom shell 15, pressing any position on the faceplate 111 will cause it to move downwards, thereby triggering the switch component 19. For example, when pressing the faceplate 111 at approximately the center, the first hook moves downwards relative to the first slot, and the push arm 112 drives the middle cover plate 161 to press against the switch component 19, thus triggering it. When pressing the edge of the faceplate 111, the faceplate 111 rotates around the engaging structure on the opposite side of the pressing position, and the first hook near the pressing side moves downwards relative to the first slot, causing the push arm 112 to drive the middle cover plate 161 to press against the switch component 19, thus triggering it.

[0241] The combination and implementation of other components, such as the first waterproof elastic element 17 and its pressure-sealing method, are related to... Figure 1 and Figure 2 The implementation method shown is the same and can be directly applied here, so it will not be repeated here. In addition, the relevant structures in this embodiment have been described in any of the previous embodiments, and will not be repeated here.

[0242] This embodiment is based on the middle cover, bottom shell and sealing components to form a signal transmitter module with complete functions. Then, a face cover is added on this basis. Since the face cover does not perform waterproofing functions, its design and material selection are more flexible. Users can further process the signal transmitter module according to their actual needs and preferences to obtain different shapes, which can meet the needs of different users.

[0243] Example 5

[0244] The signal transmitter provided in Embodiment 5 of the present invention has the following structure: Figure 11 and Figure 12 As shown, the difference from the signal transmitter provided in Embodiment 4 is that it also includes 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 can be interconnected or set independently. When interconnected, the second sealing cavity and the first sealing cavity are connected through the bottom shell through hole 158 opened on the bottom shell 15.

[0249] The bottom shell 15 has an inner plate 156 on its bottom shell, which has a bottom shell through hole 158 connecting 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; a power supply mounting position is provided on the side of the control plate 13 near the bottom shell 15, and the power supply mounting position is located in the second sealing cavity.

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

[0251] Figure 11 and Figure 12 These are, respectively, an exploded view and a cross-sectional structural diagram of the signal transmitter in this embodiment. Figure 7 and Figure 8 The main difference in the structures shown is that, Figure 11 and Figure 12 The signal transmitter shown also includes a faceplate positioned above the middle cover.

[0252] Specifically, such as Figure 11 and Figure 12 As shown, the signal transmitter includes a middle cover 16, a front cover 11, a control board 13, a bottom shell 15, a lower cover 12, a first waterproof elastic element 17, and a second waterproof elastic element 14. The middle cover 16 includes a middle cover plate 161 and a middle cover sidewall 163. The front cover 11 includes a front cover panel 111, a front cover sidewall 113, and a push arm 112. The bottom shell 15 includes a bottom shell base plate 151, a bottom shell sidewall 153, and a bottom shell inner wall 152, with the bottom shell sidewall 153 located around the bottom shell inner wall 152. The first waterproof elastic element 17 cooperates with the middle cover 16 and the bottom shell 15, and the second waterproof elastic element 14 cooperates with the lower cover 12 and the bottom shell 15 to form a sealed cavity. The control board 13 is located within the sealed cavity, and a power supply mounting position is provided on the side of the control board 13 away from the middle cover 16 for holding a power supply 18. The control board 13 is connected to a switch component 19.

[0253] The front cover sidewall 113 is located around the middle cover sidewall 163, and the bottom shell sidewall 153 is located between the middle cover sidewall 163 and the front cover sidewall 113. The middle cover sidewall 163 has a third hook 167, which is a protrusion formed on the outer side of the middle cover sidewall 163. The bottom shell sidewall 153 has a second hook 1510 that cooperates with the third hook 167, which is a protrusion formed on the inner side of the bottom shell sidewall 153. The middle cover 16 and the bottom shell 15 are engaged by the third hook 167 and the second hook 1510. The faceplate sidewall 113 has a first hook 117, which is a protrusion formed on the inner side of the faceplate sidewall 113. The bottom shell sidewall 153 has a first groove 155 that engages with the first hook 117. The first groove 155 is a groove formed on the outer side of the bottom shell sidewall 153. The faceplate 11 and the bottom shell 15 are engaged by the first hook 117 and the first groove 155.

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

[0255] The bottom plate 151 of the bottom shell has a groove structure formed by two protrusions. The first waterproof elastic element 17 is disposed in the groove structure. The middle cover plate 161 is provided with a first protrusion 165. When the middle cover 16 and the bottom shell 15 are engaged, the first protrusion 165 presses the first waterproof elastic element 17 against the bottom plate 151 of the bottom shell, causing the first waterproof elastic element 17 to undergo elastic deformation, thereby forming a good sealing contact. Similarly, the first waterproof elastic element 17 can also adopt other contact methods with the middle cover 16 and the bottom shell 15 as described above, which have been described in detail above and will not be repeated here.

[0256] The specific structure of the lower cover 12 and its contact and engagement methods with the bottom shell 15 are as follows: Figure 1 and Figure 2 The implementation methods have been described in detail. Figure 11 and Figure 12 The same structure applies here, and will not be elaborated further.

[0257] like Figure 12As shown, the control board 13 is fixed to the bottom shell 15 (as mentioned above, it can be fixed by adhesive or rivets) and is located approximately at the center of the signal transmitter. The switch component 19 is located approximately at the center of the control board 13. Pressing the front cover panel 111 causes it to move downwards. The push arm 112 presses against the middle cover plate 161, causing the first waterproof elastic element 17 to deform elastically. The middle cover plate 161 then moves downwards accordingly, pressing against the switch component 19 and triggering it. The button command generation circuit in the control board is then activated and generates a corresponding button command. The signal generator further transmits the wireless control signal based on this button command. After the external force is removed, under the combined action of the elastic restoring force of the first waterproof elastic element 17 and the upward thrust generated by the reset of the switch component 19, the middle cover plate 161, the first waterproof elastic element 17, and the front cover panel 111 return to their initial state. The switch component 19 resets, and the button command generation circuit in the control board is disconnected.

[0258] Similarly, the middle cover plate 161 can be made of a rigid material or an elastic material. When the middle cover plate 161 is made of an elastic material, pressing the front cover plate 111 causes the middle cover plate 161 to undergo elastic deformation under the action of the push arm 112, thereby triggering the switch component 19. In this case, when the front cover plate 111 is pressed, in addition to the elastic deformation of the middle cover plate 161, the first waterproof elastic element 17 may also undergo elastic deformation as described above. Correspondingly, when the external force is removed, the force that restores the front cover plate 111 to its initial state may 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 element 17 and the upward thrust generated by the reset of the switch component 19.

[0259] By means of the engaging structure between the faceplate 11 and the bottom shell 15, pressing any position on the faceplate 111 will cause it to move downwards, thereby triggering the switch component 19. For example, when pressing the faceplate 111 at approximately the center, the first hook 117 moves downwards relative to the first slot 155, and the push arm 112 drives the middle cover plate 161 to press against the switch component 19, thus triggering it. When pressing the edge of the faceplate 111, the faceplate 111 rotates around the engaging structure on the opposite side of the pressing position, and the first hook 117 near the pressing side moves downwards relative to the first slot 155, causing the push arm 112 to drive the middle cover plate 161 to press against the switch component 19, thus triggering it.

[0260] This embodiment is based on the middle cover, bottom shell, lower cover, first waterproof elastic component and second waterproof elastic component to form a signal transmitter module with complete functions. Then, a face cover is added on this basis. Since the face cover does not perform waterproof functions, its design and material selection are more flexible, which makes it convenient for users to further process the signal transmitter module according to their actual needs and preferences to obtain different shapes and meet the needs of different users.

[0261] The relevant structures in this embodiment have been described in any of the previous embodiments, and will not be repeated in this embodiment.

[0262] Example 6

[0263] The signal transmitter provided in Embodiment Six of the present invention has the following structure: Figure 13 and Figure 14 As shown, with Figure 1 and Figure 2 The difference in the signal transmitter shown is that its waterproof structure does not use a first waterproof elastic element, but rather an elastic buffer element. The signal transmitter provided in this embodiment, based on embodiment one, further includes an elastic buffer element 27. The elastic buffer element 27 is located between the faceplate 11 and the switch component 19. The elastic buffer element 27, together with the faceplate 11 and the bottom shell 15, forms a first sealed cavity, and the control plate 13 is located within the first sealed cavity. Under external force, the faceplate 11 moves towards the bottom shell 15, causing the elastic buffer element 27 to deform, and triggering the switch component through the elastic buffer element 27. After the external force disappears, the faceplate 11 returns to its original position under the restoring force generated by the elastic buffer element 27. The signal transmitter provided in this embodiment is... Figure 13 and 14 The information transmitter shown is without the bottom cover, meaning the bottom shell is a single piece, similar to... Figure 1 and Figure 2 The bottom shell shown.

[0264] The elastic buffer 27 includes an elastic cover 271 and an elastic outer edge 273; the face cover 11 is provided with a first protrusion 115, and the bottom shell 15 is provided with a second protrusion. The second protrusion can be a separate protrusion structure or it can be made using the inner wall 152 of the bottom shell. The second protrusion abuts against the inner surface of the side wall of the elastic cover 271, and the first protrusion 115 presses the elastic outer edge against the panel of the bottom shell 15 to form a first sealing cavity. Figure 14 The example shown uses the inner wall of the bottom shell. The specific structure and design of the elastic buffer are described in detail in Embodiment Seven later.

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

[0266] In this embodiment, the signal transmitter employs an elastic buffer for waterproof sealing. The elastic buffer is positioned between the faceplate and the switching component, providing support to the faceplate and preventing it from triggering the switching component without external force. The elastic buffer, together with the faceplate and bottom shell, forms a first sealed cavity, housing electrical components such as the control board, achieving waterproofing and dustproofing to meet the needs of humid or dusty environments. When the faceplate is subjected to external force, the elastic buffer deforms under pressure, triggering the switching component. After the external force disappears, the elastic buffer returns to its original shape, providing a rebound force that allows the faceplate to reset.

[0267] Example 7

[0268] The signal transmitter provided in Embodiment 7 of the present invention has the following structure: Figure 13 and 14 As shown, the signal transmitter provided in Embodiment 6 differs from the one provided in that it also includes 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 connected through a through hole 158 opened on the bottom shell 15.

[0269] The cover 11 includes a cover sidewall 113 and a panel 111. The switch component 19 is located between the elastic buffer 27 and the control plate 13, and is set in the middle of the control plate 13. Pressing any position of the panel 111 will cause the elastic buffer 27 to deform as the pressed position moves towards the bottom shell 15. The elastic buffer 27 abuts against and triggers the switch component 19. After the external force disappears, the cover is reset under the restoring force generated by the elastic buffer 27.

[0270] The bottom shell 15 includes the bottom shell sidewall 153 and the bottom plate 151. One of the bottom shell sidewall 153 and the top cover sidewall 113 is provided with a first hook, and the other is provided with a first slot adapted to the shape of the first hook. The height of the first hook is less than the height of the first slot. After the first hook and the first slot are engaged, the first hook can move within the first slot by no more than a set distance.

[0271] The details regarding the second waterproof elastic element 14 cooperating with the lower cover 12 and the bottom shell 15 to form the second sealing cavity are as described in the previous embodiments and will not be repeated here.

[0272] The inner plate 152 of the bottom shell 15 is provided with a through hole connecting 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; a power supply mounting position is provided on the side of the control plate 13 near the bottom shell 15, and the power supply mounting position is located in the second sealing cavity.

[0273] In this embodiment, the elastic buffer can be a silicone sleeve, and the second waterproof elastic component can be an elastic sealing ring.

[0274] Specifically, such as Figure 13 and Figure 14 As shown, the signal transmitter of this embodiment includes a faceplate 11, a control board 13, a bottom shell 15, a lower cover 12, an elastic buffer 27, and a second waterproof elastic element 14. The faceplate 11 includes a faceplate panel 111 and a faceplate sidewall 113. The bottom shell 15 includes a bottom shell base plate 151, a bottom shell sidewall 153, and a bottom shell inner wall 152. The bottom shell sidewall 153 is located around the inner wall 152. The elastic buffer 27 is a sealing cover structure, and the second waterproof elastic element 14 is a sealing ring structure. The elastic buffer 27 cooperates with the faceplate 11 and the bottom shell 15, and the second waterproof elastic element 14 cooperates with the lower cover 12 and the bottom shell 15 to form a sealed cavity. The control board 13 is located inside the sealed cavity and uses a... Figure 1 and Figure 2 The control board 13 is fixed to the bottom shell 15 in a similar manner. A power supply mounting position is provided on the side of the control board 13 away from the front cover 11 for holding a power supply 18, which supplies power to the control board 13. A switch component 19 is connected to the control board 13.

[0275] The elastic buffer 27 includes an elastic cover 271 and a sealing outer edge 273 extending outward along the edge of the elastic cover 271. The elastic buffer 27 is fitted onto the inner wall 152 of the bottom shell. The front cover panel 111 has a first protrusion 115. When the front cover 11 and the bottom shell 15 are engaged, the first protrusion 115 presses the sealing outer edge 273 against the bottom plate 151 of the bottom shell, forming a sealed contact. Similarly, when the lower cover 12 is engaged with the bottom shell 15, the lower cover 12 forms a sealed 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 panel 13, the switch component 19, and the power supply 18 are all located within the sealed cavity to achieve waterproofing.

[0276] like Figure 14As shown, the control board 13 is located approximately at the center of the signal transmitter, and the switch component 19 is located approximately at the center of the control board 13. At least a portion of the elastic cover 271 is an elastic structure; for example, the connection between the sealing cover and the outer edge of the seal is made of an elastic material, or the portion of the sealing cover corresponding to the switch component 19 is made of an elastic material. Pressing the faceplate 111 causes it to displace downwards, and the elastic cover 271 displaces downwards accordingly. The faceplate 111, through the elastic cover 271, presses against the switch component 19, triggering the switch component 19. The button command generation circuit in the control board is then activated and generates a corresponding button command. The signal generator further transmits the wireless control signal based on this button command. 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 faceplate 111 returns to its initial state, the switch component 19 resets, and the button command generation circuit in the control board is deactivated. Similarly, by means of the engagement structure between the face cover 11 and the bottom shell 15, pressing any position of the face cover panel 111 will cause the face cover panel 111 to move downward, thereby triggering the switch component 19.

[0277] Similarly, the faceplate 111 can be made of a rigid material or an elastic material. When the faceplate 111 is made of an elastic material, pressing the faceplate 111 causes it to deform elastically under the action of external force. The elastic cover 271 correspondingly undergoes downward displacement or deformation. The faceplate 111, through the elastic cover 271, presses against the switch component 19, thereby triggering the switch component 19. After the external force is removed, under the combined action of the elastic restoring force of the faceplate 111 and the elastic cover 271, and the upward thrust generated by the reset of the switch component 19, the faceplate 111 returns to its initial state, the switch component 19 resets, and the button command generation circuit in the control board is disconnected.

[0278] In some embodiments, the faceplate has a push arm (not shown in the figure). Pressing the faceplate causes it to move downward, and the push arm presses against the switch component through the sealing cover, thereby triggering the switch component.

[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 front cover panel has a first protrusion, and the bottom shell plate has two first protrusions. The first protrusion on the front cover panel and one of the first protrusions on the bottom shell plate are directly opposite each other. An elastic outer edge is fitted around the other first protrusion on the bottom shell plate and fixed thereon. The elastic outer edge abuts against the end faces of the two directly opposite first protrusions, forming a sealed contact. Similarly, the two first protrusions on the bottom shell plate can be independent structures, or they can together form different parts of a single structure, for example, a stepped structure. Similarly, the structural configurations on the front cover and the bottom shell can be interchanged.

[0284] The elastic buffer and the bottom shell 15 surround to form a sealed inner cavity. The control board 13, the switch component 19 and the power supply 18 are all located in the inner cavity to achieve waterproofing.

[0285] The combination and implementation of other components, such as the engagement and contact method between the lower cover and the bottom shell, the engagement method between the front cover and the bottom shell, and the fixing method between the control plate and the bottom shell, are also important considerations. Figure 1 and Figure 2 The embodiments shown have been described in detail and can be directly applied here, so they will not be repeated here.

[0286] The first sealing element in this embodiment adopts a sealing cap structure, which has a better moisture-proof effect and can achieve a more stable and long-term seal compared to the use of a sealing ring. A lower cover is also provided, which is removable. Removing the lower cover exposes the power supply through the opening in the first bottom shell, allowing for direct disassembly and installation of the power supply and making battery replacement more convenient.

[0287] Example 8

[0288] The signal transmitter provided in Embodiment 8 of the present invention has the following structure: Figure 15 and 16 As shown, the signal transmitter has a middle cover 16 and an elastic buffer 27 disposed between the face cover 11 and the control plate 13; the elastic buffer 27 is located between the middle cover 16 and the switch component 19, and the elastic buffer 27, the middle cover 16 and the bottom shell 15 cooperate to form a first sealed cavity, and the control plate 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, causing the elastic buffer 27 to deform, and triggering the switch component 19 through the elastic buffer 27; after the external force disappears, the face cover 11 and the middle cover 16 are reset under the action of the restoring force generated by the elastic buffer 27.

[0289] The elastic buffer 27 includes an elastic cover 271 and an elastic outer edge 273. The middle cover 16 has a first protrusion 165, and the bottom shell has a second protrusion 1511. The second protrusion 1511 abuts against the inner surface of the side wall of the elastic cover 271. The first protrusion 165 presses the elastic outer edge 273 against the bottom plate of the bottom shell 15, forming a first sealing cavity. A middle cover through hole 168 is provided in the middle of the middle cover. The elastic buffer 27 has a buffer protrusion 279, which passes through the middle cover through hole 168 and abuts against the top cover 11. A push arm 112 is provided in the middle of the top cover 11, which abuts against the buffer protrusion 279.

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

[0291] Figure 15 and Figure 16 These are, respectively, an exploded view and a cross-sectional structural diagram of the signal transmitter in this embodiment. The signal transmitter employs an elastic buffer for waterproofing and moisture resistance, and a central cover opening is provided on the central cover plate. Specifically, as shown... Figure 15 and Figure 16 As shown, the signal transmitter includes a middle cover 16, a control board 13, a bottom shell 15, an elastic buffer 27, and a front cover 11. The middle cover 16 includes a middle cover plate 161 and a middle cover sidewall 163, with a middle cover opening 168 on the middle cover plate 161. The elastic buffer 27 is an elastic cover, such as a silicone cover or a rubber cover, which includes an elastic cover body 271 and an elastic outer edge 273 extending outward along the edge of the elastic cover body 271. A second protrusion 162 is provided on the middle cover plate 161. When the middle cover 16 is engaged with the bottom shell 15, the second protrusion 162 presses the elastic outer edge 273 against the bottom plate 151 of the bottom shell. At this time, the elastic cover and the bottom shell surround to form a sealed inner cavity, in which the control board 13, the switch component 19, and the power supply 18 are all located, to achieve waterproofing.

[0292] A second protrusion 1511 is provided on the bottom plate 151 of the base shell. An elastic outer edge 273 is fitted around the second protrusion 1511 to fix the elastic buffer 27 and prevent it from moving. The inner side of the second protrusion 1511 also has a limiting part 1512. The edge of the control plate 13 is fixed to the bottom plate 151 by engaging with the limiting part 1512. Alternatively, the control plate 13 can also be fixed to the bottom plate 151 by adhesive bonding or riveting. It should be understood that this protrusion, which simultaneously achieves the functions of limiting the elastic buffer and fixing the control plate, can also be applied to other embodiments of the present invention. Furthermore, Figure 16The sealing and pressure-resistant method shown is merely an example; other pressure-resistant sealing methods can also be used. Specifically, as mentioned above, the elastic outer edge is equivalent to the aforementioned elastic ring structure, and a sealing contact can be achieved by using the same pressure-resistant method as the aforementioned elastic ring structure. Since the relevant implementation methods have been described in detail above, they will not be repeated here.

[0293] The resilient cover 271 further includes a resilient panel 2712 and a resilient sidewall 2711. Figure 16 (Unnumbered, see numbering in 18) The elastic panel 2712 has a buffer protrusion 279. The buffer 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 buffer protrusion 279, and the buffer protrusion 279 does not contact the switch component 19; the two are separated by a certain distance. In some embodiments, the buffer protrusion 279 may also contact the switch component 19. The control board 13 is located approximately at the center of the signal transmitter, and the switch component 19 is located approximately at the center of the control board 13. Pressing the face cover panel 111 causes the face cover panel 111 to move downward. The push arm 112 presses against the switch component 19 through the elastic cover 271, triggering the switch component 19. The button command generation circuit in the control board 13 is turned on and generates a corresponding button command. The signal generator further completes the transmission of wireless control signals based on the button command. 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 faceplate 111 returns to its initial state, the switch component 19 resets, and the button command generation circuit in the control board is disconnected. Similarly, through the structure of the faceplate 11 engaging with the bottom shell 15, pressing any position of the faceplate 111 will cause the faceplate 111 to move downward, thereby triggering the switch component 19.

[0294] In practice, the elastic protrusion is not essential, and the positional relationship between the elastic protrusion, the push arm, and the opening in the center cover can be flexibly designed. For example, in some embodiments, the elastic protrusion passes through the opening in the center cover; in this case, the push arm can be flexibly retained or omitted. In some embodiments, the elastic protrusion is located below the opening in the center cover, and the push arm passes through the opening in the center cover. In some embodiments, the elastic panel has a generally planar structure, and the push arm 112 passes through the opening 168 in the center cover. However, regardless of the presence or specific arrangement of the elastic protrusion, the elastic cover is in contact with the push arm. Under the action of external force, the push arm triggers the switching component through the elastic cover. After the external force is removed, the elastic cover, under the action of elastic restoring force, helps the faceplate panel return to its initial state.

[0295] although Figure 15 and Figure 16The elastic cushioning element shown is a silicone cap or a rubber cap, but in fact, as mentioned above, it is a sealing cap structure that includes a silicone cap or a rubber cap, or a sealing cap structure that includes an elastic cap body and an elastic outer edge. For example, the elastic cushioning element can be a sealing cap that combines an elastic cap body and an elastic outer edge with a plastic structure.

[0296] The combination and implementation of other components, such as the engagement method between the middle cover and the top cover and the bottom shell, are the same as those in the previous embodiments and can be directly applied here, so they will not be described again here.

[0297] In this embodiment, the faceplate directly presses against the switch component through the elastic cover, which is more flexible in operation compared to the case where the middle cover is in between. Furthermore, since the faceplate does not perform any waterproofing function, the design of materials and structure is more flexible, allowing users to further customize it according to their preferences.

[0298] Example 9

[0299] The signal transmitter provided in Embodiment 9 of the present invention has the following structure: Figure 17 and 18 As shown, in addition to the elastic buffer 27 and the middle cover 16, the signal transmitter also has 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 connected through a through hole opened on the bottom shell 15.

[0300] The face cover 11 includes a face cover sidewall 113 and a panel 111. The switch component 19 is located between the elastic buffer 27 and the control plate 13, and is disposed in the middle of the control plate 13. Pressing any position of the panel 111 will cause the elastic buffer 27 to deform at the pressed position of the panel 111 and the middle cover 16 to move towards the bottom shell. The elastic buffer 27 abuts against and triggers the switch component 19. After the external force disappears, the face cover 11 and the middle cover 16 are reset under the action of the restoring force generated by the elastic buffer 27.

[0301] The bottom shell 15 includes a bottom shell sidewall 153 and a bottom plate 151. One of the bottom shell sidewall 153 and the top cover sidewall 113 is provided with a first hook, and the other is provided with a first slot adapted to the shape of the first hook. The height of the first hook is less than the height of the first slot. After the first hook and the first slot are engaged, the first hook can move within the first slot by no more than a predetermined distance. The middle cover 16 includes a middle cover sidewall 163 and a middle cover plate 161. A second hook is provided on the bottom shell sidewall 153, and a third hook is provided on the middle cover sidewall 163. After the bottom shell 15 and the middle cover 16 are fastened together, the second hook and the third hook cooperate, allowing the middle cover 16 to move towards the bottom shell 15 by no more than a predetermined distance. After the front cover 11 and the bottom shell 15 are fastened together, and the middle cover 16 and the bottom shell 15 are fastened together, pressing the middle part of the panel 111 allows the front cover 11 and the middle cover 16 to move as a whole toward the bottom shell 15, so that the panel 111 abuts against the elastic buffer 27, triggering the switch component through the elastic buffer 27; pressing the panel 111 off-center allows the pressed side of the panel 111 and the middle cover 16 to pivot relative to the side away from the pressed position, so that the panel 111 abuts against the elastic buffer, triggering the switch component through the elastic buffer 27.

[0302] The relevant structures of the first and second sealing cavities are described in the previous embodiments and will not be repeated here. In summary, the elastic buffer is a silicone sleeve and the second waterproof elastic element is an elastic sealing ring.

[0303] Figure 17 and Figure 18 These are exploded views and cross-sectional structural diagrams of the signal transmitter of this embodiment. The signal transmitter includes a middle cover 16, a front cover 11, a control plate 13, a bottom shell 15, a lower cover 12, an elastic buffer 27, and a second waterproof elastic element 14. The middle cover 16 includes a middle cover plate 161 and a middle cover side wall 163, with a middle cover opening 168 on the middle cover plate 161. The front cover 11 includes a front cover panel 111 and a front cover side wall 113. The bottom shell 15 includes a bottom shell base plate 151, a bottom shell side wall 153, and a bottom shell inner wall 152, with the bottom shell side wall 153 located around the bottom shell inner wall 152. The elastic buffer 27 is a sealing cover structure, and the second waterproof elastic element 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 element 14 cooperates with the lower cover 12 and the bottom shell 15 to form a sealed cavity. The control panel 13 is located within the sealed cavity and is fixed to the bottom plate 151 of the base shell by means of adhesive bonding or riveting. A power supply mounting position is provided on the side of the control panel 13 away from the middle cover 16 for holding the power supply 18. A switch component 19 is connected to the control panel 13.

[0304] The elastic buffer 27 includes an elastic cover 271 and a sealing outer edge 273 extending outward along the edge of the elastic cover 271. The bottom plate 151 of the bottom shell has a protrusion 1511, and the elastic buffer 27 is fitted onto the protrusion 1511. The middle cover 161 has a protrusion 165. When the middle cover 16 and the bottom shell 15 are engaged, the protrusion 165 presses the sealing outer edge 273 against the bottom plate 151 of the bottom shell, forming a sealed contact. Similarly, when the lower cover 12 is engaged with the bottom shell 15, the lower cover 12 forms a sealed 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 panel 13, the switch component 19, and the power supply 18 are all located within the sealed cavity to achieve waterproofing.

[0305] The resilient cover 271 further includes a resilient panel 2712 and a resilient sidewall 2711. The resilient panel 2712 has a buffer protrusion 279. The buffer protrusion 279 further includes a raised panel 2791 and a raised sidewall 2792. At least a portion of the buffer protrusion 279 is a resilient structure. For example, the side of the raised sidewall 2792 away from the raised panel 2791 is made of a resilient material, or the portion of the raised panel 2791 corresponding to the switch member 19 is made of a resilient material.

[0306] like Figure 18 As shown, the buffer protrusion 279 extends through the opening 168 in the middle cover. The control board 13 is located approximately at the center of the signal transmitter, and the switch component 19 is located approximately at the center of the control board 13. Pressing the faceplate 111 causes it to move downwards, pressing against the switch component 19 through the buffer protrusion 279, thus triggering the switch component 19. This activates the button command generation circuit in the control board and generates a corresponding button command, which the signal generator uses to further transmit the wireless control signal. After the external force is removed, the faceplate 111 returns to its 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. The switch component 19 resets, and the button command generation circuit in the control board disconnects. Similarly, through the engagement structure between the faceplate 11 and the bottom shell 15, pressing any position on the faceplate 111 will cause it to move downwards, thereby triggering the switch component 19.

[0307] Similarly, the faceplate 111 can be made of a rigid material or an elastic material. When the faceplate 111 is made of an elastic material, pressing the faceplate 111 causes it to deform elastically under the action of external force. The buffer protrusion 279 correspondingly undergoes downward displacement or deformation. The faceplate 111, through the buffer protrusion 279, presses against the switch component 19, thereby triggering the switch component 19. After the external force is removed, under the combined action of the elastic restoring force of the faceplate 111 and the buffer protrusion 279, and the upward thrust generated by the reset of the switch component 19, the faceplate 111 returns to its initial state, the switch component 19 resets, and the button command generation circuit in the control board is disconnected.

[0308] In some embodiments, the faceplate has a push arm (not shown). Pressing the faceplate causes it to displace downwards, and the push arm presses against the switch component through the sealing cover, triggering the switch component. When the faceplate has a push arm, the buffer protrusion does not need to pass through the central cover opening; instead, it can extend into or below the central cover opening. Correspondingly, the push arm extends into or through the central cover opening to effectively drive the switch component. Furthermore, when the faceplate has a push arm, the buffer protrusion can be omitted, and the push arm can effectively drive the switch component by passing through the central cover opening.

[0309] Example 10

[0310] The signal transmitter provided in Embodiment 10 of the present invention, see [link to Embodiment 10]. Figure 19 and Figure 20 As shown, the difference from the previous embodiment is that it also includes an inner cover 26, a middle cover 16 with a middle cover through hole 164, and a buffer elastic member 27 with an elastic member through hole 278. The inner cover 26 cooperates with the middle cover through hole 164 and the elastic member through hole 278 to form a second receiving cavity. The inner cover 26 includes an inner cover sidewall 263 and an inner cover plate 261. An inner cover hook 265 is provided on the inner cover sidewall 263. The inner cover hook 265 cooperates with the through hole of the middle cover 16 to realize the engagement of the inner cover 26 and the middle cover 16.

[0311] The elastic element through hole 278 has an outer edge, and the inner cover sidewall 263 presses the outer edge of the through hole against the control plate, so that a seal is formed between the buffer elastic element 27 and the control plate 13. A power supply mounting position is provided in the second receiving cavity.

[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 engagement method between the middle cover and the top cover and the bottom shell, the specific structure of the elastic cover, the relationship between the elastic cover, the push arm and the switch component, the positional relationship between the elastic protrusion and the opening of the middle cover, and the way in which the middle cover and the bottom shell form a sealed contact with the elastic cover, are the same as the relevant implementation methods in the previous embodiments and can be directly applied here, so they will not be described again here.

[0316] This embodiment facilitates the installation and removal of the power supply by adding an inner cover. For example, when replacing the battery, only the front cover and inner cover need to be removed, without removing the middle cover and elastic cover. This also reduces the exposure of the control board and switching components, which helps the signal transmitter achieve long-term stable operation.

[0317] Similarly, other structures with inner covers can also be used. For example, based on the signal transmitter structure with a middle cover in the previous embodiment, a 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. The inner cover is disposed at the middle cover opening and engages with the middle cover plate 161 to form a sealed contact. The specific engagement method between the inner cover and the middle cover plate 161 is as described above and will not be repeated here.

[0318] When setting an inner cover for a signal transmitter structure with a middle cover in the previous embodiment, it should be ensured that the inner cover and the middle cover form a sealed contact when the inner cover and the middle cover are engaged, so that the middle cover, the inner cover, the seal and the bottom shell form a sealed inner cavity, and the control board, switch components and power supply are placed in the inner cavity to achieve the purpose of waterproofing.

[0319] For the sealing method where the middle cover and bottom shell are sealed using a first waterproof elastic element, a third waterproof elastic element is provided between the inner cover and the middle cover plate to achieve a sealed contact between the inner cover and the middle cover. For the sealing method where the middle cover and bottom shell are sealed using an elastic buffer element, a middle cover opening is formed on the middle cover plate at a position corresponding to the power installation position of the control board 13. The inner cover is set at the middle cover opening, engages with the middle cover plate, and forms a sealed contact using the elastic buffer element.

[0320] In some embodiments, the third waterproof elastic element is an elastic ring, which can be a silicone ring or rubber ring made of an elastic material such as silicone or rubber. When the inner cover and the middle cover are engaged, the third waterproof elastic element abuts against the inner cover and the middle cover. See [link to specific implementation details] for details. Figures 21-23 As shown.

[0321] like 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 sealed contact between the inner cover and the middle cover plate. The outer edge structure 262 has an outer edge protrusion 264, which, together with the inner cover sidewall 263, forms a groove structure to limit the movement of the third waterproof elastic member 24. 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 is applicable to various embodiments with a middle cover at the front, including cases where an elastic buffer element is used as the sealing element and cases where a waterproof elastic element, such as a sealing ring, is used as the sealing element. When an elastic buffer element is used as the sealing element, its structure is the same as in this embodiment. Figure 19 and Figure 20 As shown. When a waterproof elastic element is used as the sealing element, a sealing ring can be set between the inner cover and the middle cover to achieve waterproofing between them. The structure and design of the sealing ring refer to the relevant description of the sealing ring between the middle cover and the bottom shell in the previous embodiment, and will not be repeated here.

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

[0327] Based on the same inventive concept, embodiments of the present invention also provide a signal transceiver system, including a signal receiver and a signal transmitter, wherein the signal transmitter can be the signal transmitter provided in any of the above embodiments.

[0328] A signal receiver is installed in an electronic device to receive control signals sent by a signal transmitter and to control the electronic device to perform corresponding operations based on the control signals.

[0329] Electronic devices include electronic doorbells, alarms, robot vacuum cleaners, electric curtains, toilets, lighting fixtures, water heaters, or bathroom heaters. As described in the previous embodiments, each switch element is represented by a single element. In practical applications, two to four switch elements can be arranged around the perimeter of the circuit board. Pressing any edge will trigger one or two specific switch elements, transmitting a wireless radio frequency signal containing this signal.

[0330] The aforementioned signal transmitter can be widely used in electronic devices. These devices receive control signals from the transmitter via a signal receiver and execute pre-defined operations based on the received signals. For example, in some embodiments, the electronic device is a doorbell or alarm that emits a corresponding alert sound based on the received control signal. In other embodiments, the electronic device is a toilet that performs pre-defined flushing or other operations based on the received control signal. Furthermore, the electronic device can also be a robotic vacuum cleaner, electric curtains, lighting fixtures, water heaters, or bathroom heaters. In other words, the signal transmitter of this invention has a simple structure, is compact and lightweight, and is suitable for various wireless control scenarios. Moreover, due to its excellent waterproof performance, it is particularly suitable for electronic devices operating in humid environments, such as toilets, water heaters, or bathroom heaters.
