[0009] The pull-type triggering assembly comprises a transmission member and a pulling member, wherein the transmission member comprises a first transmission segment and a second transmission segment connected to each other, one end of the first transmission segment away from the second transmission segment is rotatably connected to the base, the first transmission segment is movably connected to the button, and one end of the second transmission segment away from the first transmission segment is connected to one end of the pulling member, the other end of the pulling member is located outside the call switch.

[0010] The call switch is configured such that the transmission member is linked to the button through the first transmission segment, so that the triggering mode of the micro switch of the function assembly comprises directly pressing the button and rotating the transmission member by pulling the pulling member and pressing the button.

[0011] In some possible implementation manners, the accommodation space formed by the cover and the base has a guide groove for accommodating the pulling member and defining a pulling path of the pulling member.

[0012] In some possible implementation manners, the guide groove comprises a first vertical guide segment, a second vertical guide segment and a horizontal guide segment.

[0014] The lower end is an end close to the base, and the upper end is an end close to the cover.

[0015] In some possible implementation manners, the cover comprises a cover body and a first pressing rib, and a gap is formed between the first pressing rib and a bottom wall of the base, so that the lower end of the first vertical guide segment is in communication with the lower end of the second vertical guide segment.

[0016] In some possible implementation manners, the second transmission segment has a triggering portion for triggering the micro switch.

[0017] In some possible implementation manners, the button comprises a pressing portion and a sliding portion, one end of the sliding portion is connected to the pressing portion, and the other end of the sliding portion is movably connected to the base.

[0018] The sliding portion is provided with a driving hole, and the driving hole is movably connected to the first transmission segment, so that when the transmission member rotates, the first transmission segment can press the hole wall of the driving hole.

[0019] In some possible implementation manners, the driving hole is non-circular and is matched with the structure of the first transmission segment.

[0020] In some possible implementation manners, the sliding portion is a hollow structure, and the opposite two side walls of the sliding portion are respectively provided with the driving hole and a avoiding hole.

[0021] The first transmission segment penetrates through the driving hole and the avoiding hole at the same time, and the avoiding hole is used for preventing interference caused by rotation of the first transmission segment.

[0022] In some possible implementation manners, the pressing type triggering assembly further comprises an elastic reset member, one end of the elastic reset member is connected to the button or the first transmission segment, and the other end of the elastic reset member is connected to the base.

[0023] The elastic reset member is configured to reset the button and the transmission member.

[0027] In a non-locked state, a free end of the locking portion abuts against a side wall of the locking member;

[0028] In a locked state, a top wall of the locking portion facing the face cover abuts against a bottom wall of the locking member facing the base.

[0034] The functional assembly further comprises a circuit board, and the circuit board has a circuit area.

[0035] A projection of the circuit area on the base is farther away from the pulling member than a projection of the jack on the base.

[0036] The technical scheme provided by the embodiment of the present application has at least the following beneficial effects:

[0037] The call switch provided by the embodiment of the present application has the following two triggering modes by setting the pressing type triggering assembly and the pulling type triggering assembly:

[0038] One is a button triggering mode, in which the user directly presses the button and triggers the micro switch through the first transmission segment linkage; the other is a pulling triggering mode, in which the user pulls the pulling member, the pulling member drives the transmission member to rotate around the base, and the rotating transmission member triggers the micro switch through the first transmission segment linkage button thereon.

[0039] Since the pulling member can be provided in the form of a long length of a pulling rope, for users who are inconvenient to move or have limited height, although they cannot touch the button, they can trigger the call switch through the pulling member to make a call alarm in time. When the user uses the call switch, the user can select a triggering mode that meets his or her own needs and the environment in which he or she is located.

[0040] In particular, for the pulling type triggering assembly, the transmission member is rotatably connected to the base through the end of the first transmission segment, and the first transmission segment is movably connected to the button. The transmission member moves in a rotating manner, and the button moves in a translational manner. The two are linked, that is, the rotating transmission member can drive the button to move in translation. Compared with the driving button moving in cooperation with the inclined wedge block, the rotating driving mode related to the embodiments of the present application has at least the following advantages: the driving force of the button is larger and more stable; the pulling force borne by the pulling member is larger, and the problem that the pulling type triggering assembly fails due to the user's excessive pulling force does not occur; and the problem of abnormal noise caused by the sliding of the inclined wedge block to the limit position does not occur.

[0041] In addition, the transmission member is connected to the base and the pulling member through the opposite two ends thereof, that is, the rotation shaft support point and the pulling support point are distributed at the two ends of the transmission member. According to the principle of mechanics, the longer the force arm is, the more labor-saving it is. It can be seen that this makes the pulling process more labor-saving. In summary, the call switch provided by the embodiments of the present application is more reliable, stable, labor-saving, and has better user experience. BRIEF DESCRIPTION OF DRAWINGS

These drawings and text are not intended to limit the scope of the inventive concept in any way, but to illustrate the inventive concept to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0079] 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.

[0080] 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 is defined as "up," and the position of the base is defined as "down."

[0081] 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.

[0082] This invention provides a call switch, such as... Figure 1 -Appendix Figure 2 As shown, the call switch includes: a panel assembly 1, a base assembly 2, a push-button trigger assembly 3, a pull-pull trigger assembly 4, and a functional component 5. The panel assembly 1 includes a cover 12, and the base assembly 2 includes a base 21. Figure 3 It can be seen that the press-type trigger component 3, the pull-type trigger component 4, and the functional component 5 are all located within the accommodating space formed by the face cover 12 and the base 21.

[0083] For the push-to-trigger component 3, as shown in the attached document... Figure 2 As shown, the push-button trigger assembly 3 includes a button 31 movably connected to the base 21 and extending through the panel assembly 1. For the pull-type trigger assembly 4, as shown in the attached diagram... Figure 2 As shown, the pull-type trigger assembly 4 includes a transmission member 41 and a pull member 42. The transmission member 41 includes a first transmission segment 411 and a second transmission segment 412 connected to each other. The end of the first transmission segment 411 away from the second transmission segment 412 is rotatably connected to the base 21. The first transmission segment 411 is also movably connected to the button 31. The end of the second transmission segment 412 away from the first transmission segment 411 is connected to one end of the pull member 42. The other end of the pull member 42 is located outside the call switch.

[0084] The call switch provided by the embodiment of the present application is configured such that the transmission member 41 is linked with the button 31 through the first transmission segment 411, so that the triggering mode of the micro switch 51 of the functional assembly 5 includes directly pressing the button 31 and rotating the transmission member 41 to press the button 31 by pulling the pulling member 42.

[0085] The triggering action of the micro switch 51 can be directly provided by the button 31 or directly provided by the second transmission segment 412, and any of the above-mentioned solutions can achieve the purpose of triggering the micro switch 51 and further making the functional assembly 5 transmit the call alarm signal.

[0086] The call switch provided by the embodiment of the present application has the following two triggering modes by setting the pressing type triggering assembly 3 and the pulling type triggering assembly 4:

[0087] One is the button triggering mode, in which the user directly presses the button 31 and simultaneously links the transmission member 41 through the first transmission segment 411, thereby triggering the micro switch 51; the other is the pulling triggering mode, in which the user pulls the pulling member 42, the pulling member 42 drives the transmission member 41 to rotate around the base 21, and the rotating transmission member 41 links the button 31 through the first transmission segment 411 thereon, thereby triggering the micro switch 51.

[0088] Since the pulling member 42 can be set in the shape of a long length of pulling rope, for users who are inconvenient to move or have limited height, although they cannot touch the button 31, they can trigger the call switch through the pulling member 42 to call for help in time. When using the call switch, the user can select the triggering mode that meets his own needs and the environment he is in.

[0089] In particular, for the pulling type triggering assembly 4, the transmission member 41 is rotatably connected with the base 21 through the end of the first transmission segment 411, and the first transmission segment 411 is movably connected with the button 31, the transmission member 41 moves in a rotating manner, and the button 31 moves in a translational manner, and the two are linked, that is, the rotating transmission member 41 can drive the button 31 to move in translation. Compared with the driving of the button 31 by the inclined wedge block, the rotating driving mode related by the embodiment of the present application has at least the following advantages: the driving force of the button 31 is larger and more stable; the pulling force borne by the pulling member 42 is larger, and the problem that the pulling type triggering assembly 4 fails due to the user's excessive pulling force does not occur; and the problem of abnormal sound generated when the inclined wedge block slides to the limit position does not occur.

[0090] In addition, the transmission member 41 is connected with the base 21 and the pulling member 42 through opposite ends, that is, the pivot point and the pulling point are distributed at the two ends of the transmission member, according to the mechanical principle, the longer the force arm, the more labor-saving, so that the pulling process is more labor-saving.

[0091] In some implementations, as shown in the accompanying drawings, Figure 3 The accommodation space formed by the face cover 12 and the base 21 has a guide groove 7 for accommodating the pulling member 42 and defining the pulling path of the pulling member 42.

[0092] The pulling member 42 can be designed as a long pulling rope, and the guide groove 7 is arranged to accommodate and guide the pulling member 42, so that the pulling member 42 will move along the pulling path defined by the guide groove 7 when being pulled, thereby ensuring that the pulling force of the pulling member 42 is accurately and efficiently transmitted to the first transmission section 411 to rotate it, and this also facilitates the smooth resetting of the pulling member 42 to the position without unexpected deviation when the transmission member 41 is reset.

[0093] Further combining Figure 3 It can be seen that the guide groove 7 comprises a first vertical guide section 71, a second vertical guide section 72 and a horizontal guide section 73; the first vertical guide section 71 and the second vertical guide section 72 are arranged side by side, the lower end of the first vertical guide section 71 communicates with the lower end of the second vertical guide section 72, the upper end of the second vertical guide section 72 communicates with one end of the horizontal guide section 73, and the other end of the horizontal guide section 73 is exposed to the outer wall of the call switch. The above-mentioned lower end is the end close to the base 21, and the upper end is the end close to the face cover 12.

[0094] The first vertical guide section 71 and the second vertical guide section 72 cooperatively form a U-shaped structure, the connecting end of the second transmission section 412 is located at the upper part of one side of the U-shaped structure, and the horizontal guide section 73 is located at the upper part of the other side of the U-shaped structure, so that the connecting end of the pulling member 42 is connected with the connecting end of the second transmission section 412 above the first vertical guide section 71, and is sequentially distributed through the first vertical guide section 71, the second vertical guide section 72 and the horizontal guide section 73 to make the pulling end of the pulling member 42 extend to the outer wall of the call switch in the horizontal direction.

[0095] The structure of the guide groove 7 is thus arranged, so that the pulling member 42 can drive the transmission member 41 to rotate labor-savingly and smoothly when being pulled, and the connecting end of the second transmission section 412 can be pulled down when the pulling member 42 is pulled in the horizontal direction, so that the transmission member 41 is further driven to rotate.

[0096] In some examples, referring to Figure 3A connecting hole is provided at the connecting end of the second transmission section 412, with the axis of the connecting hole in the vertical direction. The connecting end of the pulling member 42 is connected to the connecting end of the second transmission section 412 through the connecting hole. For example, the connecting end of the pulling member 42 can pass through the connecting hole and extend above the connecting hole. Then, a locking structure is provided at the connecting end of the pulling member 42 located above the connecting hole, and the locking structure is used to cooperate with the connecting hole to stop the movement.

[0097] For example, the locking structure can be a knot formed by winding the connecting end of the pull member 42, or a locking device that is detachably connected to the connecting end of the pull member 42.

[0098] The pull end of the pull member 42 can extend through the outer wall of the call switch 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.

[0099] The aforementioned "outer wall of the call switch" can be provided by at least one of the side panel portion of the panel 11 and the side panel portion of the mounting bracket 22. In some examples, as shown in the attached diagram... Figure 3 As shown, the pull end of the pull member 42 passes through the side portion of the fixing frame 22 and the side portion of the panel 11 in sequence to extend to the outside of the call switch.

[0100] In some examples, such as the attached Figure 3 and attached Figure 4 As shown, the face cover 12 includes: a face cover body 120 and a first pressure rib 121. The first pressure rib 121 and the bottom wall of the base 21 form a gap 74, which allows the lower end of the first vertical guide section 71 to be connected to the lower end of the second vertical guide section 72.

[0101] By providing a first pressure rib 121 on the cover 12, the portion of the pull member 42 located between the first vertical guide section 71 and the second vertical guide section 72 is limited. This allows the pull member 42 to bend from this position, thereby ensuring that its portion in the first vertical guide section 71 is distributed in the vertical direction, and thus enabling the connecting end of the second transmission section 412 to be pulled downward.

[0102] Of course, it is not excluded that a limiting rib with the same function can also be set on the base 21. The structure of the limiting rib is slightly different from that of the first pressure rib 121, and the same purpose can be achieved.

[0103] Furthermore, to ensure that the pulling path of the pulling member 42 within the horizontal guide section 73 is horizontal, as shown in the attached... Figure 3As shown, a second support rib 221 can also be provided on the fixed frame 22, and a second pressure rib 111 can be provided on the panel 11. The second support rib 221 and the second pressure rib 111 cooperate to form a horizontal guide section 73. The second support rib 221 is used to horizontally support the pulling member 42, and the second pressure rib 111 is used to horizontally press down the pulling member 42, thereby realizing the horizontal guidance of the horizontal guide section 73 on the pulling member 42.

[0104] As mentioned above, the triggering action of the micro switch 51 can be directly provided by the button 31 (in this case, the triggering end of the micro switch 51 is opposite to the button 31), or it can be directly provided by the second transmission section 412 (in this case, the triggering end of the micro switch 51 is opposite to the second transmission section 412). (The attached text appears to be incomplete and requires further context.) Figure 5 and attached Figure 6 Both examples illustrate that the triggering action of the micro switch 51 is directly provided by the second transmission section 412.

[0105] As attached Figure 5 and attached Figure 6 As shown, the second transmission section 412 has a trigger part 4121, which is used to trigger the micro switch 51.

[0106] Appendix Figure 5 The example illustrates the state of the call switch in its initial state, by... Figure 5 It can be seen that in the initial state, both the transmission component 41 and the button 31 are in the initial position, and the trigger end of the micro switch 51 is not triggered by the trigger part 4121.

[0107] Appendix Figure 6 The example illustrates the state of the call switch in the triggered state. The triggering action of the call switch can include the following two types:

[0108] First, the user pulls the pull member 42, which in turn drives the transmission member 41 to rotate until the transmission member 41 rotates to its corresponding limit position. At the same time, the linkage button 31 is pressed down to its corresponding limit position. At this time, the trigger end of the micro switch 51 is pressed down by the trigger part 4121 and thus triggered.

[0109] Secondly, the user directly presses down on button 31. Button 31 moves downward to its corresponding limit position. Simultaneously, button 31, in conjunction with transmission component 41, rotates, pulling pull component 42, which in turn drives transmission component 41 to rotate until it reaches its corresponding limit position. At this point, the trigger end of micro switch 51 is triggered by the trigger part 4121 pressing downward. Understandably, during this triggering process, pull component 42 is passively pulled by the rotating transmission component 41.

[0110] In this embodiment of the invention, a trigger part 4121 is provided on the second transmission section 412 to trigger the micro switch 51. The trigger part 4121 is located between the rotating end and the pulling connection end of the transmission member 41, which reduces the pressing stroke of the micro switch 51 to a certain extent and prevents excessive pressing of the micro switch 51. This is extremely beneficial for protecting the service life of the micro switch 51. Of course, compared with directly pressing the micro switch 51 by providing a trigger part on the button 31, this method involved in this embodiment of the invention also effectively buffers the pressing force of the micro switch 51, preventing damage to the micro switch 51 due to excessive or too rapid pressing force.

[0111] Understandably, the micro switch 51 typically includes two types: the first type is one where the trigger terminal is pressed and then quickly resets; the second type is one where the 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. The micro switch 51 is subordinate to the functional component 5. Understandably, the functional component 5 also includes a circuit board 52, on which a control circuit is provided. This control circuit is electrically connected to the micro switch 51. After the micro switch 51 is pressed and activated, the control circuit receives the call alarm signal and sends the call alarm signal to the terminal device. The terminal device may be, for example, a pager, which, upon receiving the call alarm signal, can make an audible call to achieve the alarm purpose.

[0112] 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.

[0113] 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.

[0114] In some examples, embodiments of the present invention may use a first type of micro switch 51, the trigger end of which is generally designed as an elastic sheet 510, wherein the first end of the elastic sheet 510 is connected to the outer wall of the micro switch 51, and the second end of the elastic sheet 510 is upturned and located above the micro switch 51. The micro switch 51 has a trigger head, which is located in the gap between the elastic sheet 510 and the micro switch 51 and is close to the first end of the elastic sheet 510. The upturned second end of the elastic sheet 510 is used to interact with the trigger portion 4121 to be pressed down and triggered.

[0115] As a typical example, the position of the trigger head of the micro switch 51 can be made to correspond to the position at the half length of the transmission member 41, so that the stroke of the trigger portion 4121 pressing the second end of the elastic sheet 510 is half of the pulling stroke of the puller 42. The length of the transmission member 41 refers to the dimension in the direction from the rotating end to the connecting end connected with the puller 42. In this way, better protection effect of the micro switch 51 can be achieved, and the micro switch 51 can be effectively triggered.

[0116] In some examples, as shown in Figure 11 and Figure 13 , the two sides of the end of the first transmission segment 411 away from the second transmission segment 412 are respectively provided with rotating shafts 4111; in combination with Figure 10 and Figure 13 , the first connecting bracket 213 is arranged at the corresponding position of the base 21, and the first connecting bracket 213 is provided with a shaft hole, which is rotatably connected with the rotating shaft 4111. In this way, the rotatable connection between the transmission member 41 and the base 21 is achieved.

[0117] In some examples, as shown in Figure 7 , the second transmission segment 412 is in the shape of a block, and the trigger portion 4121 is arranged at one side of the second transmission segment 412. For example, the trigger portion 4121 is in the shape of a pressing plate, such as a rectangular pressing plate, which is easy to be formed and prepared.

[0118] Further referring to Figure 7 , in combination with Figure 8 and Figure 9 , the button 31 comprises a pressing portion 311 and a sliding portion 312, one end of the sliding portion 312 is connected to the pressing portion 311, and the other end of the sliding portion 312 is movably connected to the base 21. The sliding portion 312 is provided with a driving hole 313, and the driving hole 313 is movably connected with the first transmission segment 411, so that when the transmission member 41 rotates, the first transmission segment 411 can press the hole wall of the driving hole 313.

[0119] The pressing portion 311 of the button 31 penetrates the button via hole 14 on the panel assembly 1, which is designed to be pressed by the user. For example, the pressing portion 311 is in the shape of a common round sheet. Further, in order to improve the pressing feeling, rough convex points or pattern structures can be arranged on the top wall of the pressing portion 311, or a soft coating can be arranged on the top wall of the pressing portion 311.

[0120] In some examples, as shown in Figure 4As shown, the inner wall of the face cover 12 is provided with a second limiting sleeve 123, which coaxially communicates with the button through hole 14 thereon, and the second limiting sleeve 123 is used to limit and guide the pressing part 311, so that the pressing part 311 can only move in the vertical direction.

[0121] The button 31 is movably connected with the base 21 by the sliding part 312 thereof, so that the button 31 moves in the vertical direction.

[0122] The driving hole 313 is arranged on the sliding part 312 of the button 31, and the driving hole 313 is used to accommodate the first transmission segment 411, so that when the first transmission segment 411 rotates downward, the bottom wall of the first transmission segment 411 presses the bottom wall of the driving hole 313 downward, thereby causing the button 31 to move in the pressing direction.

[0123] The first transmission segment 411 penetrates the driving hole 313, and the end thereof away from the second transmission segment 412 extends to the outside of the sliding part 312.

[0124] In order to make the driving force between the first transmission segment 411 and the button 31 more efficient and reliable, the structure of the driving hole 313 is matched with that of the first transmission segment 411, that is, the contour shapes of the two are consistent, so that they can be gap-fitted.

[0125] The driving hole 313 can be a circular hole or a non-circular hole, for example, the driving hole 313 can be a non-circular hole, such as an elliptical hole, a square hole, a rectangular hole, a rhombic hole, or other regular or irregular non-circular geometric shapes. It can be understood that the cross-sectional shape of the first transmission segment 411 is consistent with the contour shape of the driving hole 313, for example, the driving hole 313 is an elliptical hole, and the cross-sectional shape of the first transmission segment 411 is also elliptical.

[0126] By arranging the shapes of the driving hole 313 and the first transmission segment 411 as above, the two are limited to each other, so that they cannot rotate relative to each other, which not only facilitates the efficient assembly of the button 31 and the transmission member 41 (for example, the first transmission segment 411 of the transmission member 41 penetrates the driving hole 313 on the button 31, and the two cannot rotate relative to each other, so that a combined assembly with a desired assembly relationship can be obtained), but also prevents the button 31 from tilting, overturning, and other undesirable displacements when the transmission member 41 drives the button 31 to move downward.

[0127] As shown in the accompanying drawings, Figure 8 The sliding part 312 is a hollow structure, and the opposite two side walls of the sliding part 312 are respectively provided with the driving hole 313 and the avoiding hole 314; the first transmission segment 411 simultaneously penetrates the driving hole 313 and the avoiding hole 314, and the avoiding hole 314 is used to prevent interference with the rotation of the first transmission segment 411.

[0128] The first transmission section 411 is in the form of a connecting rod, so that the driving hole 313 is close to the rotating end of the first transmission section 411, and the avoiding hole 314 is close to the second transmission section 412, so as to improve the driving force of the first transmission section 411, and make the driving of the first transmission section 411 on the button 31 more efficient.

[0129] It can be understood that the avoiding hole 314 cooperates with the inner cavity of the sliding part 312 to form a movement cavity of the first transmission section 411, and the avoiding hole 314 can be provided in various shapes, as long as it can meet the requirement that it will not interfere with the rotation of the first transmission section 411.

[0130] For example, the avoiding hole 314 is arranged in an open form on the side wall of the sliding part 312 facing the second transmission section 412, the lower end of the avoiding hole 314 extends to the lower end of the corresponding side wall of the sliding part 312, for example, and the upper end of the avoiding hole 314 extends above the corresponding side wall. As an example, the avoiding hole 314 can be a round rectangular hole.

[0131] In some examples, two groups of reinforcing ribs can also be symmetrically arranged at the connection between the first transmission section 411 and the second transmission section 412, which not only can improve the stiffness of the transmission member, but also can position the button 31 sleeved on the first transmission section 411, and improve the efficient and accurate assembly of the button 31 and the transmission member 41.

[0132] As mentioned above, the sliding part 312 is in a hollow structure and movably connected to the base 21, for example, as shown in Figure 3 and Figure 10 The base 21 is provided with a guide structure 215 at a corresponding position, and the sliding part 312 is slidably connected with the guide structure 215, so that the sliding part 312 slides under the guidance of the guide structure 215.

[0133] For example, the sliding part 312 is in the form of a sleeve, and the guide structure 215 is in the form of a shaft sleeve matched with the structure of the sliding part 312, so that the sliding part 312 can be sleeved outside the guide structure 215, or the guide structure 215 can be sleeved outside the sliding part 312, for example, both of which are in a circular profile.

[0134] The guide structure 215 and the sliding part 312 are slidably matched, and guide the up-and-down sliding of the sliding part 312, so as to realize the pressing movement of the sliding part 312 relative to the base 21, and the guide structure 215 also helps to position the sliding part 312, so that it can only reciprocate along the pressing direction (i.e. the vertical direction), and cannot displace in the horizontal direction.

[0135] As shown in the accompanying Figure 3As shown, the push-type trigger assembly 3 further comprises an elastic reset member 32, one end of the elastic reset member 32 is connected with the button 31 or the first transmission segment 411, and the other end of the elastic reset member 32 is connected with the base 21; the elastic reset member 32 is configured to make the button 31 and the transmission member 41 perform a reset movement.

[0136] The elastic reset member 32 can be an elastic structure such as a tension spring or a compression spring, for example, the elastic reset member 32 is a compression spring. The direction of the elastic force of the elastic reset member 32 acting on the button 31 or the transmission member 41 is parallel to the pressing direction of the button 31, and the elastic reset member 32 applies an elastic force to the button 31 or the transmission member 41, so that the button 31 or the transmission member 41 slides away from the micro switch 51 to realize the reset of the button 31 and the transmission member 41.

[0137] For example, a connecting sleeve or a connecting protruding column is arranged in the inner cavity of the guide structure 215 on the base 21 to be sleeved with the lower end of the elastic reset member 32. The connecting mode of the upper end of the elastic reset member 32 includes but is not limited to the following two modes:

[0138] First, the upper end of the elastic reset member 32 is connected with or abuts against the inner cavity of the sliding part 312, for example, a partition plate is arranged in the inner cavity of the sliding part 312, so that the upper end of the elastic reset member 32 extends into the inner cavity of the sliding part 312 and abuts against the partition plate (not shown in the figure).

[0139] Second, referring to Figure 3 , the bottom of the part of the first transmission segment 411 located in the inner cavity of the sliding part 312 is provided with a connecting structure 4112, which can be a Figure 3 protruding column as shown in the figure, or a groove, so that the upper end of the elastic reset member 32 extends into the inner cavity of the sliding part 312 and is connected with the connecting structure 4112 at the bottom of the first transmission segment 411.

[0140] In some examples, as shown in the accompanying Figure 11 , the second transmission segment 412 has a locking part 4122; further combining Figure 12 , it can be known that the call switch further comprises a locking member 211 connected with the base 21, the locking member 211 is adaptively connected with the locking part 4122, and is used to lock the transmission member 41 at the position of triggering the micro switch 51.

[0141] Understandably, the transmission member 41 has an initial position and a position to trigger the micro switch 51. The initial position of the transmission member 41 corresponds to the off state before the call switch is triggered. The position of the transmission member 41 to trigger the micro switch 51 corresponds to the call alarm state after the call switch is effectively triggered. When the transmission member 41 is in the position to trigger the micro switch 51, the trigger part 4121 on the transmission member 41 is pressed down and abuts against the trigger end of the micro switch 51.

[0142] By setting the locking part 4122 and the locking member 211, the transmission member 41 is locked in the position of triggering the micro switch 51, so that the transmission member 41 is kept in the state of touching 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.

[0143] There are multiple locking methods between the locking part 4122 and the locking member 211, and the unlocking method between the two can be self-unlocking or unlocking by the unlocking member 6.

[0144] In some examples, such as the attached Figure 12 As shown, the locking element 211 is a spring clip, and one end of the locking element 211 is connected to the base 21; see further details. Figure 13 In the unlocked state, the free end of the locking part 4122 abuts against the side wall of the locking member 211; see further. Figure 14 In the locked state, the top wall of the locking part 4122 facing the cover 12 abuts against the bottom wall of the locking member 211 facing the base 21. The free end of the locking part 4122 refers to the end that is away from the second transmission section 412 and faces the locking member 211.

[0145] See Figure 13 When the call switch is switched from the off state to the call alarm state, the transmission component 41 rotates downward toward the base 21. At this time, the free end of the locking part 4122 can slide relative to the spring-shaped locking part 211. The spring-shaped locking part 211 is squeezed and abuts against the free end of the locking part 4122 to achieve relative sliding between the two.

[0146] See Figure 14 Once the rotational stroke of the transmission component 41 is complete, the call switch is in the call alarm state, and the free end of the locking part 4122 is no longer opposite to the locking component 211. In this way, the spring-shaped locking component 211 is reset under the action of elastic force, and the top wall of the locking part 4122 abuts against the bottom wall of the locking component 211. Thus, the transmission component 41 cannot rotate upward, thereby achieving locking.

[0147] See Figure 13One end of the spring-shaped locking element 211 is connected to the base 21, while the other end of the spring-shaped locking element 211 is a free end. One end of the spring-shaped locking element 211 can be connected to the base 21 in various ways, including but not limited to: snap-fit, riveting, bonding, and screw connection. Taking snap-fit ​​as an example, as shown in the attached... Figure 13 As shown, the end of the locking member 211 is configured as a hook, and a second connecting bracket 214 is provided at the corresponding position on the base 21. The second connecting bracket 214 has a slot to engage with the hook-shaped end of the locking member 211.

[0148] See in some examples Figure 10 The first connecting bracket 213 and the second connecting bracket 214 are arranged side by side on the same side of the base 21.

[0149] Further, see Figure 13 The base 21 is provided with a first support rib 212, which is used to support the locking member 211. Considering that the spring-shaped locking member 211 is relatively long, the locking member 211 is supported by providing the first support rib 212 on the base 21. For example, the bottom wall of the locking member 211 near its free end overlaps with the first support rib 212.

[0150] In some examples, the sidewall of the first support rib 212 is also used to abut against the corresponding sidewall of the transmission member 41, thereby limiting the transmission member 41. In addition, the opposite sidewall of the transmission member 41 can also abut against another limiting rib provided on the base 21. In this way, the transmission member 41 is limited in the horizontal direction, so that the transmission member 41 can only perform rotational movement and cannot perform undesirable translational movement in the horizontal direction.

[0151] In some examples, as shown in the appendix Figure 11 As shown, the trigger part 4121 and the locking part 4122 are located on opposite sides of the second transmission section 412; further combined Figure 13 Functional component 5 and locking component 211 are located on both sides of transmission component 41, respectively.

[0152] By positioning the functional component 5 and the locking element 211 on opposite sides of the transmission element 41 and separating them via the transmission element 41, when the socket 13 is provided on the panel assembly 1 corresponding to the locking element 211, the socket 13 will not be directly opposite the functional component 5. Even if water, dust, or other impurities enter the call switch through the socket 13, the impact of the water, dust, etc. on the functional component 5 is greatly reduced, which helps to improve the service life of the functional component 5.

[0153] It can be understood that the circuit area on the circuit board 52 of the functional component 5 and the locking member 211 are respectively arranged on both sides of the transmission member 41, and the non-functional area on the circuit board 52, such as the connecting area with the base 21, can extend to the lower side of the transmission member 41 or to the side where the locking member 211 is located.

[0154] As shown in FIG. 1, the call switch provided by the embodiment of the present application further comprises an unlocking member 6 configured to act on one of the locking portion 4122 and the locking member 211 to release the connection between the locking portion 4122 and the locking member 211. Figures 1-3

[0155] The unlocking member 6 can release the locking connection between the locking portion 4122 and the locking member 211, so that neither the button 31 nor the transmission member 41 is locked, and the transmission member 41 is reset under the action of the elastic reset member 32, thereby being separated from the micro switch 51 to release the call state of the call switch.

[0156] As shown in FIG. 1, the call switch provided by the embodiment of the present application further comprises an unlocking member 6 configured to act on one of the locking portion 4122 and the locking member 211 to release the connection between the locking portion 4122 and the locking member 211. Figure 1 Figure 2 As shown in FIG. 1, the call switch provided by the embodiment of the present application further comprises an unlocking member 6 configured to act on one of the locking portion 4122 and the locking member 211 to release the connection between the locking portion 4122 and the locking member 211.

[0157] For example, as shown in FIG. 2, the unlocking portion 2110 of the locking member 211 is a protruding structure, which can be obtained by bending the locking member 211 in the shape of a spring leaf, and the protruding structure extends to a position close to the unlocking end of the unlocking member 6. Figure 13 Further, in order to reduce the space occupation and improve the compact assembly of the components, as shown in FIG. 3 and FIG. 4, the second transmission segment 412 is further provided with a avoiding groove 4123 for accommodating the unlocking member 6 and providing an operation space for the unlocking member 6.

[0158] Figure 11 In combination with the above-mentioned embodiment in which the locking portion 4122 is a locking groove and the locking member 211 is a spring leaf, the unlocking member 6 can be unlocked in the following manner: Figure 13 As shown in FIG. 1, the call switch provided by the embodiment of the present application further comprises an unlocking member 6 configured to act on one of the locking portion 4122 and the locking member 211 to release the connection between the locking portion 4122 and the locking member 211.

[0159] As shown in FIG. 1, the call switch provided by the embodiment of the present application further comprises an unlocking member 6 configured to act on one of the locking portion 4122 and the locking member 211 to release the connection between the locking portion 4122 and the locking member 211.

[0160] As shown in FIG. 1, the call switch provided by the embodiment of the present application further comprises an unlocking member 6 configured to act on one of the locking portion 4122 and the locking member 211 to release the connection between the locking portion 4122 and the locking member 211. Figure 14 As shown in FIG. 1, the call switch provided by the embodiment of the present application further comprises an unlocking member 6 configured to act on one of the locking portion 4122 and the locking member 211 to release the connection between the locking portion 4122 and the locking member 211.​​​

[0161] In some examples, as shown in the accompanying drawings Figure 4 and in combination Figure 14 It can be seen that the inner part of the face cover 12 is provided with a first limiting sleeve 122, which is in communication with the insertion hole 13, and is configured to limit the rotation track of the unlocking member 6 to prevent reverse rotation thereof.

[0162] For example, referring to Figure 4 , the first limiting sleeve 122 has a semi-open sidewall, which is open between both ends, and the opening is used to allow rotation of the unlocking member 6 during unlocking operation, and the sidewall is used to prevent reverse rotation of the unlocking member 6.

[0163] In some examples, the unlocking member 6 is a key member, which is configured to be paired with the locking member 211 and the insertion hole 13 separately to prevent false unlocking.

[0164] Further, the functional assembly 5 further comprises a circuit board 52 having a circuit area thereon, and the projection of the circuit area on the base 21 is further away from the projection of the insertion hole 13 on the base 21.

[0165] Taking the application state of the call switch as an example, and defining the position of the pull member 42 as below, then the projection of the circuit area on the base 21 is above the projection of the insertion hole 13 on the base 21, so that even if water, dust and the like enter the call switch from the insertion hole 13, they will directly fall downward under the action of gravity without contacting the circuit area of the circuit board 52, effectively improving the waterproof and dustproof performance of the call switch, and improving its service life and adaptability to the external environment.

[0166] The above has exemplarily described the components contained in the pressing type trigger assembly 3, the pulling type trigger assembly 4 and the functional assembly 5 and their functions. For the panel assembly 1 and the base assembly 2, some embodiments are described as follows:

[0167] In some examples, as shown in the accompanying drawings Figure 5 and in the accompanying drawings Figure 6 , the panel assembly 1 comprises a panel 11 and a face cover 12, and the base assembly 2 comprises a base 21 and a fixing frame 22, wherein the base 21 has a receiving cavity, the face cover 12 is connected with the base 21 and covers the upper end of the receiving cavity to close the receiving cavity and form a receiving space. The fixing frame 22 is connected with the base 21 and surrounds the outer side of the base 21, and the panel 11 is connected with the base 21 and covers the face cover 12 and the base 21 to give the call switch an aesthetic appearance. The fixing frame 22 is used for installation of the call switch in the application site, for example, when the call switch is installed on the wall, the fixing frame 22 is fixedly connected with the installation box embedded in the wall.

[0168] Need to explain, the panel 11 and the face cover 12 are provided with button through hole 14 and jack 13, using button through hole 14 to expose the press part 311 of button 31, using jack 13 to allow the unlocking piece 6 to be inserted into the accommodation space.

[0169] Further, the panel 11, the face cover 12, the base 21 and the fixing frame 22 can include the side wall part, and the corresponding through hole allowing the pulling piece 42 to pass through and extend to the side of the call switch can be arranged on the side wall part.

[0170] It can be understood that the structure of the panel 11 and the fixing frame 22 can refer to the structure of the panel and the fixing frame involved in the common switch except for some special improved designs corresponding to the embodiments of the present application, which will not be described one by one here.

[0171] In combination with the structure of the call switch provided by the embodiments of the present application, the assembly mode of the call switch is described exemplarily as follows:

[0172] The pulling piece 42 is connected to the transmission piece 41, for example, one end of the rope-like pulling piece 42 is threaded through the connecting hole at the end of the second transmission section 412 of the transmission piece 41 and is tied with a knot at the end, so that the pulling piece 42 is connected to the transmission piece 41. Then, the transmission piece 41 is connected to the button 31, for example, the first transmission section 411 of the transmission piece 41 is threaded through the driving hole 313 and the avoiding hole 314 on the button 31, and finally a first assembly combination is formed.

[0173] The functional assembly 5 is connected to the base 21, for example, the circuit board 52 of the functional assembly 5 is fixed to the positioning groove on the base 21 by screws. The lower end of the elastic reset piece 32 is connected to the guide structure 215 on the base 21. One end of the spring-shaped locking piece 211 is connected to the base 21, and at the same time, the spring-shaped locking piece 211 is horizontally overlapped on the first support rib 212 inside the base 21, and finally a second assembly combination is formed.

[0174] Assembling the first assembly component with the second assembly component, which comprises: connecting the rotating shaft 4111 at the end of the first transmission segment 411 of the transmission member 41 with the first connecting bracket 213 on the base 21, while arranging the pulling member 42 in the guide groove 7 in sequence according to the structure of the guide groove 7, and making the pulling end of the pulling member 42 penetrate out of the side wall of the base 21. And, sleeving the sliding part 312 of the button 31 on the upper end of the elastic reset member 32, so that the micro switch 51 is located below and corresponds to the button 31. Buckling the face cover 12 on the base 21 to seal the accommodating cavity of the base 21, while the first pressing rib 121 on the face cover 12 presses the pulling member 42 in the guide groove 7. And, assembling the base 21 with the fixing frame 22, and assembling the face plate 11 with the fixing frame 22, thereby completing the assembly of the call switch.

[0175] In combination with the structure of the call switch provided by the embodiments of the present application, the different working modes of the call switch are described as follows:

[0176] (1) The call switch is in a pulling trigger mode

[0177] The user pulls the pulling member 42, the pulling member 42 drives the transmission member 41 to rotate around the base 21, the rotating transmission member 41 links and presses the button 31 through the first transmission segment 411 thereon. The trigger part 4121 on the second transmission segment 412 presses and triggers the micro switch 51, and the call switch performs call alarm. At the same time, the first transmission segment 411 compresses the elastic reset member 32, and the locking part 4122 cooperates with the locking member 211 to lock, so that the call switch remains in the call alarm state.

[0178] When it is necessary to release the call alarm state of the call switch, the locking member 211 is unlocked by the unlocking member 6 to release the locking with the locking part 4122, then the transmission member 41 and the button 31 are reset to move, the micro switch 51 is no longer triggered to be turned off, and the call switch is no longer in call alarm.

[0179] (2) The call switch is in a button trigger mode

[0180] The user directly presses the button 31, the button 31 moves along the pressing direction and links the transmission member 41, so that the transmission member 41 rotates around the base 21, the rotating transmission member 41 links and presses the button 31 through the trigger part 4121 on the second transmission segment 412, and the call switch performs call alarm. In the button trigger mode, the way to release the call alarm state of the call switch is the same as that in the pulling trigger mode, which is not described here.

[0181] For the trigger modes shown in (1) and (2), when the call switch has the locking portion 4122 and the locking member 211, the locking between the first locking portion 4122 and the locking member 211 is released by the unlocking member 6, and the switch is reset to the initial state.

[0182] (3) The call switch is a reset switch mode

[0183] In this mode, the locking member 211 can be removed from the call switch, i.e. the locking member 211 is not required to be installed when the call switch is assembled, so that the call switch has the reset function in the pull trigger mode and the button trigger mode.

[0184] In the embodiments of the present application, the terms "first" and "second" are only used for the purpose of description, and cannot be understood as indicating or implying relative importance. The term "a plurality of" refers to two or more, unless otherwise explicitly limited.

[0185] The above description is only for the convenience of those skilled in the art to understand the technical solutions of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
