Description

Technical Field

[0001] This invention relates to the field of alarm technology, and in particular to call switches. Background Technology

[0002] Call switches are typically used in alarm systems. Users trigger the call switch to send an alarm signal to the alarm system, thereby enabling the call alarm function.

[0003] The call switches provided by related technologies are usually installed on the wall, and the call switches are single button trigger modes, which are activated by the user by pressing the button.

[0004] However, users with mobility impairments or height limitations often face restrictions when using the button-triggered mode of the call switch, which may prevent them from making timely alarm calls. Summary of the Invention

[0022] The number of driving units is two, and the two driving units are symmetrically arranged on both sides of the outer side wall of the transmission body;

[0029] The rotating part and the rotating structure are rotatably connected in a one-to-one correspondence.

[0030] In some possible implementations, when the pull-type trigger assembly is in its initial state, the transmission body is arranged at an angle relative to the faceplate.

[0031] When the pull-type trigger component is pulled to the point where the micro switch is in the triggered state, the transmission body is parallel to the face cover.

[0032] In some possible implementations, the button includes a button body and a transmission part, the transmission part being disposed on the outer side wall of the button body, and the transmission part being provided with a stop rib;

[0033] When the pull-type trigger assembly is in its initial state, the stop rib abuts against the drive part to stop it, so that the transmission body is arranged at an angle relative to the cover.

[0046] In some possible implementations, the first locking structure is a locking groove, and the second locking structure is a spring.

[0047] In some possible implementations, the call switch further includes an unlocking element configured to act on one of the first locking structure and the second locking structure to release the connection between the first locking structure and the second locking structure.

[0048] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following:

[0049] The call switch provided in this embodiment of the invention, by setting up a press-type trigger component and a pull-type trigger component, enables the call switch to have the following two triggering modes: First, a button triggering mode, in which the user directly presses the button, triggering a micro switch; second, a pull triggering mode, in which the user pulls a pull member, which drives a transmission component to rotate around the base. The rotating transmission component, through its drive unit, presses the button, thus moving the button along the pressing direction and triggering the micro switch. Since the pull member can be designed as a relatively long pull cord, users with limited mobility or height, even if they cannot touch the button, can still trigger the call switch by pulling the pull member to promptly make an alarm call. When using the call switch, users can choose the triggering mode that best suits their needs and environment.

[0050] Specifically, for the pull-type trigger assembly, its transmission body is rotatably connected to the cover via a rotating part, and the drive part is movably connected to the button. The transmission body drives the button to move horizontally by rotation, and force is transmitted through a proportional lever rotation, allowing the wedge surface to slide smoothly. This reduces force loss, making the pulling process more time-saving and labor-saving, resulting in a better user experience. Furthermore, the rotatable connection between the rotating part and the cover is more convenient and simpler than a rotatable connection between the rotating part and the base, reducing installation steps and improving assembly efficiency.

These drawings and descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0080] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0081] The directional terms used in the embodiments of this invention, such as "upper," "lower," and "side," are generally... Figure 1 and Figure 2 The relative positions shown are based on the given information, and these directional terms are used merely to more clearly describe the relationships between structures, not to describe absolute positions. Positions may change when the product is placed in different orientations; for example, "up" and "down" may be interchanged. In this embodiment of the invention, the position of the panel assembly is defined as "up," and the position of the base is defined as "down."

[0082] To make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0083] This invention provides a call switch, such as... Figures 1-3 As shown, the call switch includes: a panel assembly 1, a base assembly 2, a push-button trigger assembly 3, a pull-type trigger assembly 4, and a functional component 5. The panel assembly 1 includes a face cover 12, the base assembly 2 includes a base 21, and the push-button trigger assembly 3, the pull-type trigger assembly 4, and the functional component 5 are all located within the accommodating space formed by the face cover 12 and the base 21.

[0084] The push-button trigger assembly 3 includes a button 31 movably connected to the base 21 and extending through the panel assembly 1. The functional component 5 includes a micro switch 51. The push-button trigger assembly 3 is configured such that pressing the button 31 can trigger the micro switch 51 to cause the functional component 5 to transmit a call alarm signal.

[0085] Combination Figure 4 It is understood that the pull-type trigger assembly 4 includes: a transmission component 41 and a pull component 42, wherein the transmission component 41 includes: a transmission body 411, and a rotating part 412 and a driving part 413 connected to the transmission body 411. (Combined) Figure 7 It can be seen that the transmission body 411 is rotatably connected to the cover 12 via the rotating part 412, and in combination Figure 5 It can be seen that the drive unit 413 and the transmission unit 311 on the button 31 are slidably engaged by the wedge surface, and the pull member 42 is connected to the transmission body 411 and passes through the panel assembly 1.

[0086] The pull-type trigger component 4 is configured such that by pulling the pull member 42, the transmission member 41 can rotate around the cover 12 via the rotating part 412, so that the drive part 413 drives the button 31 to move towards the micro switch 51 via the wedge surface, and then the button 31 triggers the micro switch 51 to make the functional component 5 transmit a call alarm signal.

[0087] The call switch provided in this embodiment of the invention, by setting a press-type trigger component 3 and a pull-type trigger component 4, enables the call switch to have the following two triggering modes: First, a button triggering mode, in which the user directly presses the button 31, triggering the micro switch 51; second, a pull triggering mode, in which the user pulls the pull member 42, which drives the transmission member 41 to rotate around the base 21. The rotating transmission member 41, through its driving part 413, presses the button 31, thus moving the button 31 along the pressing direction and triggering the micro switch 51. Since the pull member 42 can be configured as a long pull cord, even users with limited mobility or height, who cannot reach the button 31, can trigger the call switch through the pull member 42 to promptly make an alarm call. When using the call switch, the user can choose the triggering mode that suits their needs and environment.

[0088] Specifically, for the pull-type trigger assembly 4, its transmission body 411 is rotatably connected to the cover 12 via the rotating part 412, and the driving part 413 is movably connected to the button 31. The transmission body 411 drives the button 31 to move by rotation, and the force is transmitted through a proportional lever rotation, thereby allowing the wedge surface to slide. This reduces force loss, making the pulling process more time-saving and labor-saving, resulting in a better user experience. In addition, the rotating part 412 is rotatably connected to the cover 12. Compared to the rotating part 412 being rotatably connected to the base 21, this assembly method is more convenient and simpler, reducing installation steps and improving assembly efficiency.

[0089] The wedge surfaces involved in the call switch include two slidingly fitted surfaces, as shown in the attached diagram. Figure 5 As shown, the button 31 includes a button body 310 and a transmission part 311, wherein the transmission part 311 is disposed on the outer side wall of the button body 310; further, the wedge surface includes a first wedge surface 71 disposed on the transmission part 311 and a second wedge surface 72 disposed on the drive part 413, wherein the first wedge surface 71 and the second wedge surface 72 are slidably engaged.

[0090] Both the first wedge surface 71 and the second wedge surface 72 are inclined planes, their surfaces abutting each other and capable of sliding relative to each other. By moving the second wedge surface 72 upward or downward along the first wedge surface 71, the transmission part 311 is driven to move downward. All arrangements that meet this requirement are applicable to embodiments of the present invention.

[0091] In some examples, as shown in the appendix Figure 5As shown, the transmission component 41 also includes a connecting part 414, which is connected to the transmission body 411 and is used to connect with the pulling member 42; the connecting part 414, the rotating part 412 and the driving part 413 are arranged in sequence at intervals.

[0092] By positioning the rotating part 421 between the connecting part 414 and the driving part 413, and with the connecting part 414 positioned either above or below the rotating part 412, the purpose of pulling the transmission member 41 can be achieved, causing the driving part 413 to drive the button 31 downward through its wedge surface.

[0093] Appendix Figure 4 and attached Figure 5 The example shows the connecting part 414 located above the rotating part 412. In this example, the connecting part 414, the rotating part 412, and the driving part 413 are arranged sequentially at intervals along the top-to-bottom direction. The second wedge surface 72 is located at the lower end of the driving part 413. The transmission part 311 is located at the lower end of the outer side wall of the button body 310, and the first wedge surface 71 is located at the upper end of the transmission part 311. The top-to-bottom direction is the direction from the cover 12 to the base 21.

[0094] In this example, as shown in the appendix Figure 3 As shown, the first wedge surface 71 is located below the second wedge surface 72. When the second wedge surface 72 moves upward with the driving part 413, it can drive the first wedge surface 71 to move downward with the transmission part 311. This embodiment has a simple structural arrangement and is easy to assemble.

[0095] Of course, the connecting part 414 can also be located below the rotating part 412. For example, the driving part 413, the rotating part 412, and the connecting part 414 can be arranged sequentially at intervals from top to bottom (not shown in the figure); the second wedge surface 72 is located at the upper end of the driving part 413; the transmission part 311 is located at the upper end of the outer side wall of the button body 310, and the first wedge surface 71 is located at the lower end of the transmission part 311. When the second wedge surface 72 moves upward with the driving part 413, it can also drive the first wedge surface 71 to move downward with the transmission part 311.

[0096] In this embodiment of the invention, the number of driving units 413 and transmission units 311 are the same and correspond one-to-one. Taking the driving unit 413 as an example, it can be set to two or one. For example, as shown in the attached... Figure 4 As shown, if the drive unit 413 is configured as two symmetrically arranged on both sides of the transmission body 411, then the transmission unit 311 can also be configured as two symmetrically arranged. Alternatively, if the drive unit 413 is configured as one arranged on one side or in the middle of the transmission body 411, then the transmission unit 311 can also be configured as one (not shown in the figure).

[0097] Appendix Figure 5 Examples of schemes with two drive units 413 symmetrically arranged and two transmission units 311 symmetrically arranged are shown in the appendix. Figure 5 As shown, there are two transmission parts 311, symmetrically arranged on both sides of the outer wall of the button body 310; there are also two drive parts 413, symmetrically arranged on both sides of the outer wall of the transmission body 411. The drive parts 413 and the transmission parts 311 are slidably engaged through wedge surfaces. This arrangement has the advantages of stable and reliable transmission, high transmission efficiency, and long transmission life.

[0098] In this embodiment of the invention, the transmission body 411 can surround the outside of the button body 310. In this case, the drive part 413 and the transmission part 311 can be arranged opposite each other and slide together through the wedge-shaped surfaces on them. Alternatively, the transmission body 411 can also be arranged side by side with the button body 310. For example, the transmission body 411 is located on one side of the button body 310. In this case, in order to adapt to the internal arrangement of the call switch, one of the drive part 413 and the transmission part 311 can be provided with a guide rod. The guide rod can extend in a direction parallel to the cover 12, so that the drive part 413 and the transmission part 311 can slide together through the wedge-shaped surfaces on them, while avoiding increasing the volume of the call switch as much as possible.

[0099] Appendix Figure 5 The example illustrates that the transmission body 411 can surround the outside of the button body 310, further combined with the attached... Figure 7 As shown, a connecting sleeve 121 is provided on the face cover 12, and the transmission body 411 is configured as a hollow structure; the button body 310, the connecting sleeve 121, and the transmission body 411 are sequentially fitted from the inside to the outside.

[0100] Understandably, the faceplate 12 is also provided with a button through hole 13, and the upper end of the connecting sleeve 121 is connected to the inner wall of the faceplate 12 and the connecting sleeve 121 is coaxially connected with the button through hole 13.

[0101] In this configuration, the transmission body 411 and the button body 310 are arranged in a compact manner, which helps to save internal space of the call switch and reduce the size of the call switch. Furthermore, the transmission body 411 surrounds the button body 310, and the button body 310 can position the transmission body 411 in the horizontal direction, so that the transmission body 411 will not undergo undesirable displacement in the direction parallel to the cover 12, but can only rotate.

[0102] For the above implementation scheme, the positional relationship between the drive unit 413 and the transmission body 411 is adaptively determined according to the specific positional arrangement of the drive unit 413 and the transmission unit 311. As shown above, the drive unit 413 may be located above or below the rotating unit 412, etc.

[0103] As a typical example, see attached Figure 5 As shown, there are two drive units 413, which are symmetrically arranged on both sides of the outer wall of the transmission body 411. The drive units 413 extend in a vertical direction, and their upper ends are connected to the lower ends of the transmission body 411. A second wedge surface 72 is formed at the lower end of the drive unit 413. The vertical direction is the direction perpendicular to the cover 12.

[0104] As attached Figure 5 As shown, there are two transmission parts 311, which are symmetrically arranged on both sides of the outer wall of the button body 310. The transmission parts 311 extend in the horizontal direction, and one end of the transmission part 311 is connected to the lower end of the outer wall of the button body 310. The first wedge surface 71 is formed on the surface of the transmission part 311 facing the cover 12.

[0105] As described above, the transmission body 411 surrounds the button body 310. The transmission body 411 can be a fully enclosed structure or a partially enclosed structure.

[0106] In some examples, as shown in the appendix Figure 4 As shown, the transmission body 411 is a partially enclosed structure, wherein the transmission body 411 includes a partially enclosed sidewall and an opening formed between the two ends of the sidewall. This method has at least the following advantages: the transmission body 411 has a simple structure, small volume, and is easy to mold and assemble. During the rotation process, its opening can accommodate part of the button 31, thereby preventing interference with the button 31.

[0107] The inner contour of the transmission body 411 should match the outer contour of the button 31. The outer contour of the transmission body 411 can be designed in various shapes, such as circular, elliptical, rectangular, prismatic, etc. In some examples, the transmission body 411 is an easily moldable arc shape (both its inner and outer contours are arc-shaped), and it can be set as a minor arc, a major arc, or a semi-circular arc, etc. (See attached image) Figure 1 An example is provided of a transmission body 411 with a semi-circular arc structure, in which the rotating part 412 and the driving part 413 are symmetrically arranged on opposite sides, which is beneficial to the reliability, stability and efficiency of the transmission process.

[0108] Based on the above-described structure, the transmission body 411, in some examples, as shown in the attached figure... Figure 4 and attached Figure 5As shown, two rotating parts 412 are symmetrically arranged on the inner wall of the transmission body 411; two rotating structures are symmetrically arranged on the outer wall of the connecting sleeve 121; the rotating parts 412 and the rotating structures are rotatably connected in a one-to-one correspondence.

[0109] The rotating part 412 is located on the inner wall of the transmission body 411, and the rotating structure is located on the outer wall of the connecting sleeve 121. One of the rotating part 412 and the rotating structure is a rotating shaft, and the other is a circular hole or an arc-shaped groove, thereby enabling a rotatable connection between the rotating part 412 and the rotating structure. For example, the rotating part 412 is a rotating shaft, and the rotating structure is a circular hole adapted to the rotating shaft structure.

[0110] In some examples, when the pull-type trigger component 4 is in the initial state (i.e., when it is not pulled by the puller 42), the transmission body 411 is arranged at an angle relative to the cover 12. Specifically, the upper and lower surfaces of the transmission body 411, which are parallel to the cover 12, form a certain angle with the cover 12. For example, the angle can be 15° to 45°.

[0111] When the pull-type trigger assembly 4 is pulled to the trigger state of the micro switch 51, the transmission body 411 is parallel to the cover 12. That is, the upper and lower surfaces of the transmission body 411, which are parallel to the cover 12, are parallel to the cover 12.

[0112] With the above settings, the transmission component 41 is not arranged horizontally in the initial state, but is arranged at an angle relative to the horizontal plane. In this way, when the puller 42 is pulled to make the transmission component 41 rotate, the transmission component 41 will rotate to the position and the rotating component will be arranged horizontally when the micro switch 51 is triggered. This method makes the pulling process of the puller 42 and the transmission process of the transmission component 41 more labor-saving and efficient, which helps to improve the user's feel.

[0113] In some examples, as shown in the appendix Figure 5 As shown, button 31 includes button body 310 and transmission part 311. Transmission part 311 is disposed on the outer side wall of button body 310, and a stop rib 3110 is provided on transmission part 311. When the pull-type trigger assembly 4 is in the initial state, the stop rib 3110 abuts against the drive part 413 to stop, so that the transmission body 411 is arranged at an angle relative to the face cover 12.

[0114] For example, a first wedge surface 71 is disposed on the upper surface of the transmission part 311, with its upper end extending to a first side of the transmission part 311. A stop rib 3110 is located on a second side of the transmission part 311, and the stop rib 3110 and the first wedge surface 71 cooperate to form a track groove. In the initial state, the drive part 413 of the transmission member 41 is located within this track groove. The second wedge surface 72 on the drive part 413 abuts against the first wedge surface 71, and the side of the drive part 413 opposite to the second wedge surface 72 abuts against the stop rib 3110, thereby achieving a stop. When the transmission member 41 rotates, this track groove will not interfere with it.

[0115] It can be seen that the arrangement of the stop ribs 3110 can ensure the stability of the transmission component 41 in the initial state.

[0116] In some examples, the connecting part 414 can be located on the side of the transmission body 411 facing the base 21, and the pulling member 42 can extend through the side of the base 21 into its receiving cavity.

[0117] Furthermore, at least one of the cover 12 and the base 21 is provided with a guide groove, which is used to define the pulling path of the pull member 42. For example, the guide groove is provided on both the side portion of the cover 12 and the side portion of the base 21.

[0118] By setting a guide groove to accommodate and guide the pulling member 42, the pulling member 42 will move along the pulling path defined by the guide groove when it is pulled, thereby ensuring that the movement path of the pulling member 42 is consistent each time it is pulled, and accurately and efficiently transmitting its pulling force to the transmission body 411 to make it rotate. In addition, this also helps the pulling member 42 to return to its original position smoothly when the transmission body 411 is reset, without any undesirable offset.

[0119] In some examples, the guide groove is a straight groove parallel to the panel assembly 1, so that the pull end of the pull member 42 can extend through the side wall of the base 21 and the side wall of the panel assembly 1 to the side of the call switch. When the call switch is installed on the wall, its panel assembly 1 is perpendicular to the wall, and the pull member 42 can extend downward parallel to the wall until it reaches a position that is easily touched by the user.

[0120] The connection between the connecting part 414 and the pulling member 42 can be in various ways. For example, the connecting part 414 is provided with a connecting hole, and one end of the pulling member 42 is connected to the transmission body 411 through the connecting hole.

[0121] In some examples, one end of the pull member 42 can pass through the connecting hole, and then a connecting structure can be provided at that end of the pull member 42. The connecting structure is used to stop the connection with the end of the connecting hole, so as to realize the assembly of the pull member 42 on the transmission body 411.

[0122] For example, the connection structure can be a knot formed by winding the end of the pull member 42, or a clip that is detachably connected to the end of the pull member 42.

[0123] In some examples, as shown in the appendix Figure 6 As shown, the button body 310 includes: a pressing part 3101 and a sliding part 3102; one end of the sliding part 3102 is connected to the pressing part 3101, and the other end of the sliding part 3102 is movably connected to the base 21; the transmission part 311 is disposed on the outer side wall of the sliding part 3102.

[0124] The pressing part 3101 of the button 31 extends through the panel assembly 1 and is designed to be pressed by the user. For example, the pressing part 3101 is a common circular disc. Furthermore, in order to improve the pressing feel, rough bumps or textured structures can be provided on the top wall of the pressing part 3101, or a soft coating can be provided on the top wall of the pressing part 3101.

[0125] Button 31 is movably connected to base 21 by its sliding part 3102, so that button 31 moves in the vertical direction. When the user presses the pressing part 3101, button 31 moves downward and triggers micro switch 51. When button 31 is reset, it moves upward.

[0126] A transmission part 311 is provided on the outer wall of the sliding part 3102 of the button 31, and a first wedge surface 71 is provided on the transmission part 311 to achieve a sliding engagement with the second wedge surface 72 on the drive part 413.

[0127] The sliding part 3102 has a hollow structure. The sliding part 3102 can be configured as a single sleeve structure, which is used to jointly undertake the connection between the transmission component 41 and the base 21. The sliding part 3102 can also be configured as a double sleeve structure with inner and outer layers. The inner sleeve structure is used to connect with the base 21, and the outer sleeve structure is used to connect with the transmission component 41.

[0128] Appendix Figure 6 An example of a sliding part 3102 with a double-sleeve structure is shown in the attached figure. Figure 6 As shown, the sliding part 3102 includes an inner part 31021 and an outer part 31022; the inner part 31021 and the outer part 31022 are coaxially sleeved from the inside to the outside, and the same side ends of both are connected to the pressing part 3101; the inner part 31021 is also connected to the base 21, and the outer part 31022 is also connected to the transmission part 311.

[0129] The inner part 31021 is connected to the base 21, and the outer part 31022 is connected to the transmission part 311 to connect with the transmission component 41. This structural arrangement of the sliding part 3102 of the button 31 simplifies the assembly process of the button 31 and ensures a more reliable connection between it and other components.

[0130] The inner part 31021 is a hollow structure and is movably connected to the base 21. For example, a guide structure 212 is provided at a corresponding position on the base 21. The inner part 31021 is slidably connected to the guide structure 212, so that the inner part 31021 can slide under the guidance of the guide structure 212.

[0131] In some examples, as shown in the appendix Figure 6 As shown, the inner portion 31021 has a closed side enclosure. For example, the inner portion 31021 is sleeve-shaped, and the guide structure 212 is a bushing-shaped structure that is adapted to the structure of the inner portion 31021. The inner portion 31021 can be sleeved on the outside of the guide structure 212, or the guide structure 212 can be sleeved on the outside of the inner portion 31021. For example, both have a circular outline.

[0132] By utilizing the guide structure 212 to slide in conjunction with the inner part 31021 of the sliding part 3102, the sliding part 3102 is guided to slide, thereby realizing the pressing movement of the sliding part 3102 relative to the base 21. Furthermore, this also facilitates the positioning of the sliding part 3102, so that it can only reciprocate along the pressing direction (i.e., the vertical direction) and cannot be displaced in the horizontal direction.

[0133] In some examples, as shown in the appendix Figure 6 As shown, the outer portion 31022 has an open sidewall, meaning that the side of the outer portion 31022 has at least one or more openings. The outer portion 31022 connects to the transmission part 311 and then to the transmission member 41 using only its sidewall. The openings not only facilitate the assembly of the button 31 but also make it easier for the button 31 to engage with other components, such as the second locking structure 211 described below.

[0134] In some examples, as shown in the appendix Figure 6 As shown, the button 31 in this embodiment of the invention further includes a trigger part 312, which is connected to the side of the pressing part 3101 facing the base 21. The trigger part 312 is used to trigger the micro switch 51.

[0135] In other words, the trigger part 312 is located at the bottom of the pressing part 3101. For example, the trigger part 312 is configured as a rib, and the trigger part 312 is connected to the bottom of the outer side of the pressing part 3101. Furthermore, the trigger part 312 is located on one side of the outer part 31022, and its free end is located above the trigger end of the micro switch 51.

[0136] As described above, when the transmission body 411 has a partially enclosed structure, the free end of the trigger part 312 can also be located in the opening of the transmission body 411, so that there is no need to provide a through hole structure on the transmission body 411.

[0137] When button 31 is not pressed, as shown in the attached image Figure 3 As shown, the trigger part 312 is spaced apart from the trigger end of the micro switch 51. After the button 31 is pressed and moved to a certain distance, the bottom of the trigger part 312 abuts against the trigger end of the micro switch 51 and presses down the trigger end, thereby triggering the micro switch 51.

[0138] In some examples, the micro switch 51 can be arranged side by side with the button 31, as long as the trigger end of the micro switch 51 is located below the trigger part 312.

[0139] It should be noted that the micro switch 51 typically includes the following two types: the first type of micro switch 51 is activated when its trigger terminal is pressed and then quickly resets; the second type of micro switch 51 is activated when its trigger terminal is pressed and requires pressing again to reset. Both types of micro switches 51 are applicable to the embodiments of the present invention. In some examples, the embodiments of the present invention may use the first type of micro switch 51, whose trigger terminal is generally designed as an elastic sheet.

[0140] Microswitch 51 is subordinate to functional component 5, as can be understood, as shown in the attached diagram. Figure 2 and attached Figure 3 As shown, functional component 5 also includes a circuit board 52, on which a control circuit is provided. This control circuit is electrically connected to a micro switch 51. After the micro switch 51 is pressed and turned on, the control circuit receives the call alarm signal and sends the call alarm signal to the terminal device. The terminal device can be, for example, a pager, which can make an audible call after receiving the call alarm signal to achieve the alarm purpose.

[0141] In some examples, the base 21 has a positioning groove that is adapted to the structure of the circuit board 52. The circuit board 52 is accommodated and positioned in the positioning groove. Furthermore, the circuit board 52 can be connected to the corresponding position on the base 21 by fasteners, such as screws, thereby achieving stable placement in the base 21.

[0142] In addition to maintaining an electrical connection with the circuit board 52, the micro switch 51 can also be mounted on the circuit board 52. For example, the circuit board 52 has a recessed hole, and the bottom of the micro switch 51 has a protruding post, so that the protruding post can be inserted into the recessed hole to achieve stable placement of the micro switch 51 on the circuit board 52.

[0143] Regarding the aforementioned elastic reset element 32, see the following implementation scheme: In some examples, as shown in the appendix Figure 7 As shown, the push-to-trigger assembly 3 also includes: an elastic reset member 32, one end of which is connected to the sliding part 3102, and the other end of which is connected to the base 21; the elastic reset member 32 is configured to reset the pressed button 31 to disengage from the micro switch 51.

[0144] The direction of the elastic force exerted by the elastic reset member 32 on the button 31 is parallel to the pressing direction of the button 31. The elastic reset member 32 applies an elastic force to the button 31, which can cause the button 31 to slide away from the micro switch 51, thereby realizing the reset of the button 31.

[0145] For example, the elastic reset member 32 can be an elastic structure such as a tension spring or a compression spring. For instance, if the elastic reset member 32 is a compression spring, a connecting sleeve or a connecting protrusion can be provided at the corresponding position on the base 21 to be sleeved with the lower end of the compression spring, and the upper end of the compression spring can be connected to or abut against the inner cavity of the sliding part 3102.

[0146] For example, as shown in the appendix Figure 7 As shown, the sliding part 3102 includes an inner part 31021 and an outer part 31022, so that the upper end of the elastic reset member 32 is connected to the inner part 31021. For example, a partition is provided in the inner cavity of the inner part 31021, so that the upper end of the compression spring can extend into the inner cavity of the inner part 31021 and abut against the partition. Moreover, this arrangement will not affect the sliding connection between the inner part 31021 and the guide structure 212 on the base 21.

[0147] As shown above, button 31 includes: button body 310 and transmission part 311. Button body 310 includes: pressing part 3101 and sliding part 3102; further, as shown in the attached... Figure 6 and attached Figure 7 As shown, a first locking structure 313 is provided on the side wall of the sliding part 3102. The call switch also includes a second locking structure 211 connected to the base 21. The second locking structure 211 is adapted to the first locking structure 313 and is used to lock the button 31 in the position that triggers the micro switch 51.

[0148] Understandably, button 31 has an initial position and a position that triggers micro switch 51. The initial position of button 31 corresponds to the off state before the call switch is triggered, and in this initial position, button 31 and micro switch 51 are not in contact. The position where button 31 triggers micro switch 51 corresponds to the call alarm state after the call switch is effectively triggered, and in this position, button 31 and micro switch 51 are in contact. In some examples, button 31 contacts the trigger end of micro switch 51 via trigger part 312.

[0149] In some examples, the sliding portion 3102 includes an inner portion 31021 and an outer portion 31022, such that the first locking structure 313 is disposed on the outer wall of the inner portion 31021.

[0150] By setting the first locking structure 313 and the second locking structure 211, the button 31 is locked in the position of triggering the micro switch 51. In this way, after the user no longer applies pressure to the button 31, the button 31 will not spring back to its original position even if the elastic reset member 32 applies an elastic force, that is, it will not disengage from the micro switch 51. This keeps the button 31 in the state of triggering the micro switch 51, thereby avoiding the emergency call time being too short, effectively ensuring that the emergency call is heard, and improving the accuracy of the emergency call.

[0151] There can be multiple locking methods between the first locking structure 313 and the second locking structure 211, and the unlocking method between the two can be self-unlocking or unlocking by the unlocking component 6.

[0152] For example, one of the first locking structure 313 and the second locking structure 211 can be configured as a slot and the other as a protrusion. Locking is achieved by confining the protrusion within the slot, and unlocking is achieved by separating the protrusion from the slot.

[0153] Appendix Figure 7 The example illustrates that the first locking structure 313 is a locking groove, and the second locking structure 211 is a spring. When the button 31 is locked, part of the spring is located in the locking groove to prevent the button 31 from disengaging from the micro switch 51. When it is necessary to disengage the button 31 from the micro switch 51, the spring is squeezed and abuts against the side wall of the sliding part 3102 located below the first locking structure 313 to unlock the button 31.

[0154] In some examples, the sliding portion 3102 includes an inner portion 31021 and an outer portion 31022, such that a locking groove-shaped first locking structure 313 is disposed on the outer wall of the inner portion 31021. For example, the first locking structure 313 can be directly formed on the outer wall of the inner portion 31021, or a locking block 314 can be connected to the outer wall of the inner portion 31021 to provide the first locking structure 313. The top wall of the locking block 314 abuts against the bottom wall of the second locking structure 211 to achieve locking.

[0155] Understandably, the side wall of the sliding part 3102 of the button 31 can slide relative to the spring-shaped second locking structure 211. When the button 31 is pressed to move downward, the spring-shaped second locking structure 211 is squeezed and abuts against the side wall of the sliding part 3102 to achieve relative sliding between the two. That is, the second locking structure 211 does not affect the up and down movement of the sliding part 3102.

[0156] After the button 31 has been pressed to its full travel, the trigger part 312 on the button 31 triggers the trigger end of the micro switch 51. The first locking structure 313 (i.e., the locking groove) on the side wall of the sliding part 3102 is opposite to the second locking structure 211. In this way, the spring-shaped second locking structure 211 is reset under the action of elastic force and enters the locking groove, thereby locking the button 31.

[0157] For the assembly method of the spring-shaped second locking structure 211 in the base 21, please refer to the following exemplary solution:

[0158] In some examples, the sliding portion 3102 includes an inner portion 31021 and an outer portion 31022. The outer portion 31022 has an open sidewall. One end of a spring-shaped second locking structure 211 is connected to the base 21, and the other end of the spring-shaped second locking structure 211 is a free end. The second locking structure 211 passes through the cavity between the inner portion 31021 and the outer portion 31022, and its free end extends from an opening on the outer portion 31022 to the outside of the sliding portion 3102. A locking groove-shaped first locking structure 313 is disposed on the outer sidewall of the inner portion 31021 along a direction perpendicular to the pressing direction of the button 31.

[0159] When button 31 is locked, along the pressing direction perpendicular to button 31, the free end of the spring-shaped second locking structure 211 passes through the locking groove-shaped first locking structure 313. Since the spring-shaped second locking structure 211 has a suspended free end, the second locking structure 211 has good elasticity, which facilitates the spring-shaped second locking structure 211 to cooperate with button 31 and locking groove-shaped first locking structure 313 for locking.

[0160] One end of the spring-shaped second locking structure 211 can be connected to the base 21 in various ways, including but not limited to: snap-fit, riveting, gluing, screw connection, etc. Taking snap-fit ​​as an example, this end of the second locking structure 211 is set as a hook shape, and a corresponding slot shape is provided on the base 21, so that the two can be fitted together.

[0161] Furthermore, considering that the second locking structure 211 in the form of a spring is relatively long, a support rib 213 can be provided on the base 21 to support the second locking structure 211. For example, part of the bottom wall of the second locking structure 211 can be attached to the support rib 213.

[0162] In some examples, as shown in the appendix Figure 7 As shown, the call switch provided in this embodiment of the invention further includes an unlocking component 6, which is configured to act on one of the first locking structure 313 and the second locking structure 211 to release the connection between the first locking structure 313 and the second locking structure 211.

[0163] The locking mechanism 6 can release the lock between the first locking structure 313 and the second locking structure 211. In this way, the button 31 is no longer locked and will reset under the action of the elastic reset member 32, thereby disengaging the button 31 from the micro switch 51 and deactivating the call switch.

[0164] Based on the above-described implementation scheme where the first locking structure 313 is a locking groove and the second locking structure 211 is a spring piece, the unlocking component 6 can be unlocked through the following unlocking methods:

[0165] The user operates the unlocking element 6, causing it to actively compress the spring-shaped second locking structure 211, disengaging the portion of it located within the locking groove from the locking groove-shaped first locking structure 313. In some examples, the unlocking element 6 actively compresses the free end of the spring-shaped second locking structure 211 to release the lock between the first locking structure 313 and the second locking structure 211.

[0166] The free end of the spring-shaped second locking structure 211 is located on one side of the button 31, so that the unlocking member 6 will not be interfered with by the button 31 when performing the unlocking operation, and it also makes the unlocking operation more effortless.

[0167] In some examples, the panel assembly 1 is provided with a socket 14, one end of the unlocking member 6 passes through the socket 14 into the receiving space to actuate and compress the spring-shaped second locking structure 211, and the other end of the unlocking member 6 is exposed outside the panel assembly 1. In this way, it is convenient for the user to operate the unlocking member 6.

[0168] For example, the end of the unlocking component 6 that passes through the insertion hole 14 is provided with a paddle, and the free end of the spring-shaped second locking structure 211 is provided with a toggle groove, so that the paddle can enter into the toggle groove, and the unlocking component 6 can be rotated to unlock.

[0169] In some examples, the unlocking element 6 is a key element. This configuration allows the unlocking element 6 to be paired separately with the second locking structure 211 and the socket 14, preventing accidental locking events.

[0170] The above provides an exemplary description of the components and their functions included in the push-button trigger assembly 3, the pull-button trigger assembly 4, and the functional assembly 5. For the panel assembly 1 and the base assembly 2, please refer to the following embodiments:

[0171] In some examples, as shown in the appendix Figure 7 and attached Figure 8 As shown, the panel assembly 1 includes a panel 11 and a cover 12, and the base assembly 2 includes a base 21 and a fixing frame 22. The base 21 has a receiving cavity, and the cover 12 is connected to the base 21 and covers the upper port of its receiving cavity to close the receiving cavity and thus form a receiving space.

[0172] The mounting bracket 22 is connected to the base 21 and surrounds the outside of the base 21. The panel 11 is connected to the base 21 and covers the cover 12 and the base 21 to give the call switch an aesthetic appearance. The mounting bracket 22 is used for the installation of the call switch in the application environment. For example, when the call switch is installed on a wall, the mounting bracket 22 is fixedly connected to the mounting box embedded in the wall.

[0173] It should be noted that both the panel 11 and the cover 12 are provided with a button through hole 13 and a socket 14. The button through hole 13 is used to expose the pressing part 3101 of the button 31, and the socket 14 is used to allow the unlocking member 6 to be inserted into the receiving space.

[0174] Furthermore, the panel 11, the cover 12, the base 21 and the mounting bracket 22 may each include a side panel, and corresponding through holes may be provided on their side panels, which allow the pull member 42 to pass through and extend to the side of the call switch.

[0175] Understandably, apart from some special improved designs corresponding to the embodiments of the present invention, the main structures of panel 11 and bracket 22 can be referred to as the panel and bracket structures involved in common switches, and will not be described in detail here.

[0176] Based on the structure of the call switch provided in the embodiments of the present invention, the assembly method of the call switch is described below as an example:

[0177] The pull member 42 is connected to the transmission member 41. For example, one end of the rope-like pull member 42 is passed through the connecting hole on the transmission member 41 and a knot is tied at the end, so that the pull member 42 is connected to the transmission member 41. Then, the transmission member 41 is connected to the cover 12. For example, the rotating part 412 of the transmission member 41 is inserted into the pivot hole on the cover 12. Then, the button 31 is inserted into the button through hole 13 on the cover 12, and its transmission part 311 and the driving part 413 on the transmission member 41 are slidably engaged through the wedge surface, finally forming the first assembly.

[0178] The functional component 5 is connected to the base 21, for example, by fixing the circuit board 52 of the functional component 5 into the positioning groove on the base 21 with screws. The lower end of the elastic reset member 32 is connected to the connecting sleeve on the base 21. One end of the spring-shaped second locking structure 211 is connected to the base 21, and the spring-shaped second locking structure 211 is horizontally overlapped with the support rib 213 inside the base 21, thus forming the second assembly.

[0179] Assemble the first assembly assembly and the second assembly assembly, including: fitting the sliding portion 3102 of the button 31 onto the upper end of the elastic reset member 32, so that the micro switch 51 is located below and corresponding to the button 31; fastening the face cover 12 onto the base 21 to close the receiving cavity of the base 21; assembling the base 21 with the fixing bracket 22; and assembling the panel 11 with the fixing bracket 22, thereby completing the assembly of the call switch.

[0180] Based on the structure of the call switch provided in the embodiments of the present invention, the different operating modes of the call switch are described by way of example below:

[0181] (1) The call switch is in pull-triggered mode.

[0182] The user pulls the pull member 42, which drives the transmission member 41 to rotate around the base 21. The rotating transmission member 41 slides relative to the transmission member 311 on the button 31 via its drive part 413, thereby pressing the button 31. This causes the button 31 to move in the pressing direction, triggering its trigger part 312 to activate the micro switch 51, thus initiating an alarm call. Simultaneously, the button 31 compresses the elastic reset member 32, and the first locking structure 313 on the button 31 engages with the second locking structure 211 on the base 21 to lock the button 31 in the position where the micro switch 51 is triggered, maintaining the alarm call state.

[0183] When it is necessary to deactivate the call alarm status of the call switch, the second locking structure 211 is toggled by the unlocking component 6 to release it from the first locking structure 313. Then, the button 31 moves upward to reset and moves away from the micro switch 51, the micro switch 51 is turned off, and the call switch no longer calls the alarm.

[0184] (2) The call switch is in button trigger mode.

[0185] The user directly presses button 31, which moves in the pressing direction and triggers micro switch 51 via its trigger part 312, thus initiating an alarm call. In button-triggered mode, the alarm call is deactivated in the same way as in pull-triggered mode, and will not be described further here.

[0186] For the triggering modes shown in (1) and (2), when the call switch has a first locking structure 313 and a second locking structure 211, the locking between the first locking structure 313 and the second locking structure 211 is released by the unlocking member 6. As a result, the reset movement of the button 31 no longer triggers the micro switch 51 and drives the transmission member 41 to reset together, so the reset switch returns to the initial state.

[0187] (3) The call switch is in reset switch mode.

[0188] In this mode, the second locking structure 211 can be removed from the call switch, that is, the second locking structure 211 does not need to be installed when assembling the call switch. In this way, the call switch has a reset function in both pull-triggered mode and button-triggered mode.

[0189] In embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0190] The above description is merely for the purpose of enabling those skilled in the art to understand the technical solutions of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
