[0046] According to one aspect of the present invention, a trigger assembly is provided, which can be arranged on an electronic device including a circuit board 30, and the electronic device can be a device with waterproof and accidental touch prevention requirements such as a defibrillator device and a remote control device. In order to better describe the invention of the present invention, the following will take the defibrillator device as an example to specifically describe the invention content of the present invention, but it should be known that the products to which the present invention can be applied include but are not limited to the defibrillator device.

[0047] refer to Figure 1 and Figure 2 As shown, the trigger assembly includes: a housing 1, on which a mounting portion is provided, and the mounting portion is a recessed area 110 of the housing 1; Figures 3 to 5 As shown, the key structure 2 is connected to the circuit board 3, is disposed in the recessed area 110 and includes a waterproof portion 210;

[0048] The outer wall of the waterproof part 210 fits with the inner wall of the recessed area 110 , and a waterproof pre-compression groove 211 is provided on the outer wall of the waterproof part 210 , and a boss 111 which is interference-fitted with the waterproof pre-compression groove 211 is provided on the inner wall of the recessed area 110 .

[0049] Through the above technical scheme, that is, through the trigger assembly provided by the utility model, on the one hand, since the key structure is arranged in the recessed area 110, and the recessed area 110 is a recessed area on the shell, the key structure is sunken in the shell 1 for installation. Therefore, in actual application, it is necessary to reach into the recessed area 110 to touch the key structure 2, so as to achieve the technical effect of preventing accidental touch; on the other hand, since the outer wall of the waterproof part 210 and the inner wall of the recessed area 110 are in contact, and a waterproof pre-compression groove 211 is provided on the outer wall of the waterproof part 210, and a boss 111 which is interference-fitted with the waterproof pre-compression groove 211 is provided on the inner wall of the recessed area 110, thus, the waterproof pre-compression groove 211 and the boss 111 are interference-fitted, and the connection relationship is tight, which can effectively prevent water from entering from the gap between the waterproof part 210 and the recessed area 110 to achieve a waterproof effect.

[0050] On this basis, the material of the waterproof part 210 as a whole or at least the waterproof pre-compression groove 211 can be designed to be an elastic material, such as silicone. The material of the recessed area 110 as a whole or at least the boss 111 can be designed to be a plastic material, such as plastic. In this way, since at least the material of the waterproof pre-compression groove 211 is designed to be an elastic material such as silicone, and at least the boss 111 is a plastic material, and the waterproof pre-compression groove 211 and the boss 111 are interference fit, during the installation process, the groove wall of the waterproof pre-compression groove 211 can give a certain amount of compression to the boss 111, so that the fit between the two is firm and tight, thereby achieving a waterproof effect. The material of the waterproof part as a whole is designed to be silicone because silicone itself has a certain waterproof performance, so the whole is waterproof.

[0051] In addition, the key structure 2 shown in the reference figure further includes a trigger portion 220 and a key 230 ; the key 230 is disposed on the circuit board 3 , and the trigger portion 220 can move within the recessed area 110 to contact or separate from the key 230 .

[0052] In this way, when in use, the trigger portion 220 can be pressed, and the contact portion 220 moves toward the circuit board 3 in the recessed area 110 to contact the button 230. At this time, the circuit board 3 can be turned on or off by the button 230. When the trigger portion 220 is separated from the button 230, the button 230 does not work.

[0053] The present invention does not specifically limit the structure of the trigger part 220, as long as it can achieve contact or separation with the button 230. In a possible implementation, the trigger part 220 can be designed to include an elastic member, and the elastic member includes a trigger end and a contact end; wherein the contact end is an end close to the button, and the trigger end is an end away from the button 230, so that the contact end can be contacted or separated from the button 230 by squeezing the trigger end. The elastic member can be a spring or other elastic structural member with elastic properties. Optionally, refer to Figure 5 As shown, the elastic member can be designed as a structure made of silicone material, and the structure and the waterproof part are integrally formed into a silicone shell.

[0054] In one possible implementation, reference Figure 5 As shown, the key structure 2 also includes a supporting fixing member 240, which includes a supporting plate 241, wherein the supporting fixing member 240 extends along the longitudinal direction of the recessed area 110, and one end away from the circuit board 3 abuts against the trigger part 220 to support the movement of the trigger part 220 in the recessed area 110.

[0055] In this way, due to the existence of the support plate 241, on the one hand, the trigger part 220 can be supported in the longitudinal extension direction of the recessed area 110, thereby ensuring that the trigger part 220 can flexibly switch between the contact button or the separation button in the recessed area 110; on the other hand, when the trigger part 220 is moving, the waterproof part 210 is prevented from moving with the trigger part 210, thereby ensuring that the waterproof pre-compression groove 211 and the boss 111 remain in a mating state, thereby achieving a waterproof effect.

[0056] On this basis, reference Figure 5 As shown, a receiving cavity 250 may be provided between the trigger portion 220 and the waterproof portion 210 , and the support plate 241 is provided in the receiving cavity 250 to ensure the supporting stability of the support plate 241 .

[0057] In addition, since the support plate 241 will be under pressure when the trigger part 220 is pressed, in order to ensure that the support fixing member 240 has a good force-bearing function and installation reliability, in some embodiments, the support fixing member 240 can also be provided to include a fixing plate 242, and the fixing plate 242 is connected to the support plate 241 and the circuit board 3 at the same time, and the width of the fixing plate 242 is greater than the width of the support plate 241, so that the support plate 241 can be fixed on the circuit board 2, and the pressure can be dispersed through the fixing plate 242, so that the support fixing member 240 has a good force-bearing function, and since the width of the fixing plate 224 is greater than the width of the support plate 221, the connection with the circuit board 3 through the fixing plate 224 can ensure the reliability of the installation.

[0058] In a possible embodiment, the support plate 241 and the fixing plate 242 may be formed into two "L"-shaped cross sections arranged axially symmetrically, and the "1" part of the "L"-shaped cross section is the cross section of the support plate 241, and the "one" part of the "L"-shaped cross section is the cross section of the fixing plate 242; the support plate 241 and the fixing plate 242 may also be formed into two "T"-shaped cross sections arranged axially symmetrically, and the "1" part of the "T"-shaped cross section is the cross section of the support plate 241, and the "one" part of the "T"-shaped cross section is the cross section of the fixing plate 242. In this way, the support plate 241 may be formed into a cylindrical plate, and the fixing plate 242 may be formed into an annular plate.

[0059] Since the air in the accommodating chamber 250 will also be compressed when the trigger part 220 is pressed, affecting the pressing experience, for this reason, in some embodiments, a through hole 2421 connecting the accommodating chamber 250 and the external environment may be provided on the fixing plate 242. In this way, when the trigger part 220 is pressed, the compressed air is released to the external environment through the through hole 2421, and when the trigger part 220 stops being pressed, the air in the external environment can enter the accommodating chamber 250 through the through hole 2421 to give the trigger part 220 a certain counter-support force, so that the trigger part 220 quickly rebounds to the initial state before being pressed, thereby enhancing the user experience.

[0060] The utility model does not specifically limit the size and number of the through holes 2421. In some embodiments, a plurality of through holes 2421 may be provided, and the plurality of through holes 2421 are evenly spaced to ensure the air flowability in the accommodating cavity 250. Specifically, the number of through holes 2421 may be 2, 3, 4, etc.

[0061] The utility model does not specifically limit the installation and positioning method of the key structure 2. In some embodiments, the waterproof part 210 can be designed to have a connecting portion 212 that matches the fixing plate 242, and the fixing plate 242 is provided with a first positioning ear plate 2422 and a second positioning ear plate 2423; the connecting portion 212 is provided with a third positioning ear plate 2121 and a fourth positioning ear plate 2122; the mounting portion is also connected to a positioning plate 120,

[0062] There is a first positioning slit 2424 between the first positioning ear 2422 and the second positioning ear 2423; there is a second positioning slit 2123 between the third positioning ear 2121 and the fourth positioning ear 2122; the first positioning slit 2424 and the second positioning slit 2123 overlap; the positioning plate 111 passes through the second positioning slit 2123 and the first positioning slit 2424 in sequence to abut against the circuit board 3. Thus, the key structure 2, the circuit board 3 and the housing 1 can be positioned to facilitate installation.

[0063] In addition, it can be designed that the first positioning ear plate 2422 and the third positioning ear plate 2121 are respectively provided with a first positioning mounting hole 4, and the second positioning ear plate 2423 and the fourth positioning ear plate 2122 are respectively provided with a second positioning mounting hole 5, so that a fixing part can pass through the first positioning mounting hole 4 and / or the second positioning mounting hole 5 to connect to the circuit board.

[0064] Of course, those skilled in the art can choose to design only the first positioning and mounting hole 5 or only the second positioning and mounting hole 5 or both. In order to ensure the reliability of installation, the utility model is designed to have both the first positioning and mounting hole 4 and the second positioning and mounting hole 5.
