[0024] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0025] Example 1:

[0026] This embodiment discloses a vibration connecting component and a vibration sensor using the connecting component; wherein the vibration sensor is electrically connected to the circuit board through the fixed electrode 12 and the movable electrode 13, and a vibration connecting component for inducing vibration is provided on the fixed electrode 12 and the movable electrode 13, specifically, as shown in FIG. Figure 1As shown, the vibration connection component in this embodiment includes a fixed end 1, a connecting portion 3 electrically connected to the fixed end 1, and a movable end 2 electrically connected to the outer end of the connecting portion 3 and driven to move by the vibration induced by the connecting portion 3. The fixed end 1 is in contact with the fixed electrode 12, and the movable end 2 is spaced apart from the movable electrode 13. Specifically, the connecting portion 3 in this embodiment is a thin sheet-shaped and arc-shaped elastic sheet. Specifically, as shown in FIG. Figure 8 As shown, in this embodiment, the fixed end 1 is fixedly connected to the fixed electrode 12, and the movable end 2 is suspended above the movable electrode 13; when in use, the vibration connection component on the circuit board senses vibration, thereby causing the movable end 2 to move and contact the movable electrode 13, thereby achieving conduction between the fixed electrode 12 and the movable electrode 13 on the vibration sensor;

[0027] Furthermore, in order to enable the movable end 2 in the vibration connecting component to move in multiple directions such as forward, backward, left and downward after induction vibration and to connect the fixed electrode 12 and the movable electrode 13, the connecting portion 3 in this embodiment includes two connecting pieces 16 fixedly connected to the fixed end 1 and the movable end 2 respectively, a plurality of longitudinal connecting pieces 17 arranged in parallel and spaced apart and located between the two connecting pieces 16, and a plurality of transverse connecting pieces 18 connected end to end with the longitudinal connecting pieces 17, the outermost longitudinal connecting pieces 17 at the left and right ends are fixedly connected to the connecting pieces 16 respectively, so that the connecting portion 3 can drive the movable end 2 to move in the above-mentioned multiple directions after induction vibration; at the same time, in this embodiment, the movable electrode 13 includes an electrode body 15 and an electrode connecting portion 14 arranged on the electrode body 15 and located outside the contact conductive portion, and the electrode connecting portion 14 is electrically connected to the electrode body 15; as shown Figure 7 and 8 As shown, the movable electrode 13 in this embodiment is made of a metal thin plate material, and the electrode connecting portion 14 located outside the contact conductive portion is formed by bending the outer peripheral portion of the electrode body 15 upward, so that the movable end 2 can achieve contact and conduction with the upward bent electrode connecting portion 14 or the electrode body 15 when moving in multiple directions such as forward, backward, left and downward.

[0028] Furthermore, if Figure 2 and Figure 7As shown, in order to extend the contact conduction time between the vibrating connecting component and the movable electrode 13, in this embodiment, a contact conductive portion is provided on the outer side of the movable end 2 and is spaced apart from the movable end 2, and an extended conductive member electrically connected to the contact conductive portion and the movable end 2 is provided on the contact conductive portion, and the extended conductive member can be elastically deformed relative to the moving direction of the movable end 2; when the connecting portion 3 senses vibration and drives the movable end 2 to move in the corresponding direction, the contact conductive portion first contacts the movable electrode 13, and the circuit connection between the fixed electrode 12 and the movable electrode 13 begins to be realized, and then the movable end 2 continues to move in the corresponding direction. At this time, since the contact conductive portion has been in contact with the movable electrode 13 and is limited, the extended conductive member is affected The force causes elastic deformation until the driving force of the movable end 2 is completely converted into the elastic force of the extended conductive part. At this time, the movable end 2 stops moving. Then, the movable end 2 moves in the opposite direction under the action of the elastic force of the extended conductive part or the driving force in the opposite direction of the vibration sensor. At this time, the extended conductive part that is deformed by the force gradually returns to its original state. During this process, the contact conductive part and the movable electrode 13 always maintain a contact and conductive state until the extended conductive part returns to its original state and the movable end 2 continues to move in the opposite direction. The contact conductive part is separated from the movable electrode 13, so that the circuit between the fixed electrode 12 and the movable electrode 13 is disconnected, and the contact and conductive time between the fixed electrode 12 and the movable electrode 13 is achieved by the above method.

[0029] Among them, such as Figure 1 As shown, in order to increase the contact conduction time between the fixed electrode 12 and the movable electrode 13 when the movable end 2 moves to the left, the extended conductive member in this embodiment includes a first arc-shaped deformation strip 5 arranged on the side of the movable end 2 away from the fixed end 1 and arranged in the left and right directions of the horizontal plane. The middle section of the first arc-shaped deformation strip 5 is bent. Specifically, the first arc-shaped deformation strip 5 in this embodiment is a thin plate strip structure, and the middle section of the first arc-shaped deformation strip 5 is convex in the front-to-back direction toward the side away from the movable end 2. Since the bent first arc-shaped deformation strip 5 is only for the purpose of making the first arc-shaped deformation strip 5 have a certain elasticity to improve the stability of the movable end 2. The first arc-shaped deformation strip 5 is elastically deformed, so that the middle section of the first arc-shaped deformation strip 5 can also be convexly arranged in the front-to-back direction toward the side close to the movable end 2. At this time, the contact conductive portion can be directly arranged at the outermost end of the first arc-shaped deformation strip 5, and then when the movable end 2 moves to the left and the contact conductive portion contacts the movable electrode 13, the curved first arc-shaped deformation strip 5 can undergo a certain degree of elastic deformation; similarly, in this embodiment, if you want to achieve the contact conduction time between the fixed electrode 12 and the movable electrode 13 in one direction of forward, backward, left and downward separately, you only need to set a curved arc-shaped deformation strip in the corresponding moving direction on the outside of the movable end 2.

[0030] Furthermore, in this embodiment, on the basis of extending the contact conduction time between the fixed electrode 12 and the movable electrode 13 when the movable end 2 moves leftward, the contact conduction time between the fixed electrode 12 and the movable electrode 13 is further extended when the movable end 2 moves forward and backward; Figure 2 and Figure 3 As shown, in this embodiment, there are two first arc-shaped deformation bars 5, which are respectively arranged on the front and rear sides of the left end of the movable end 2, and the tail ends of the above-mentioned first arc-shaped deformation bars 5 are respectively connected to second arc-shaped deformation bars 6 arranged in the front and rear directions of the horizontal front, and the middle section of the second arc-shaped deformation bar 6 is bent; specifically, the second arc-shaped deformation bar 6 in this embodiment is also a strip structure of a thin plate, and the middle section of the second arc-shaped deformation bar 6 protrudes toward the side away from the movable end 2 in the left and right directions; similarly, the middle section of the second arc-shaped deformation bar 6 can also protrude toward the side close to the movable end 2 in the left and right directions; at this time, the contact conductive part is arranged at the tail end of the second arc-shaped deformation bar 6; similarly, the elastic deformation generated by the first arc-shaped deformation bar 5 and the second arc-shaped deformation bar 6 after being subjected to force makes the contact conductive part contact with the movable electrode 13 for a long time, thereby extending the conduction time of the fixed electrode 12 and the movable electrode 13.

[0031] Example 2:

[0032] like Figure 4 As shown, the present embodiment is different from the first embodiment in that: in order to increase the contact conduction time between the fixed electrode 12 and the movable electrode 13 when the movable end 2 moves downward, the extended conductive member can include a third arc-shaped deformation bar 8 arranged on the side of the movable end 2 away from the fixed end 1 and arranged in the left and right directions of the vertical plane, and the middle section of the third arc-shaped deformation bar 8 is bent; specifically, the third arc-shaped deformation bar 8 is also a strip structure of a thin plate, and the middle section of the third arc-shaped deformation bar 8 is protruded in the up and down direction toward the side away from the movable end 2; similarly, the middle section of the third arc-shaped deformation bar 8 can also be protruded in the up and down direction toward the side close to the movable end 2; correspondingly, at this time, the contact conductive part is arranged at the outermost end of the third arc-shaped deformation bar 8.

[0033] Furthermore, in this embodiment, on the basis of extending the contact conduction time between the fixed electrode 12 and the movable electrode 13 when the movable end 2 moves downward, the contact conduction time between the fixed electrode 12 and the movable electrode 13 is further extended when the movable end 2 moves left and right; Figure 4 and Figure 5As shown, in this embodiment, the tail end of the third arc-shaped deformation strip 8 is connected to a fourth arc-shaped deformation strip 9 arranged in the up and down directions of the vertical plane, and the middle section of the fourth arc-shaped deformation strip 9 is bent; specifically, the fourth arc-shaped deformation strip 9 in this embodiment is also a strip structure of a thin plate, and the middle section of the fourth arc-shaped deformation strip 9 is protruded in the left and right directions toward the side away from the movable end 2; similarly, the middle section of the fourth arc-shaped deformation strip 9 can also be protruded in the left and right directions toward the side close to the movable end 2; on this basis, the contact conductive part is arranged at the outermost end of the fourth arc-shaped deformation strip 9.

[0034] Furthermore, in order to simultaneously realize that the movable end 2 moves in multiple directions, such as forward, backward, leftward and downward, the contact conduction time between the fixed electrode 12 and the movable electrode 13 can be prolonged. Figure 6 As shown, the third arc-shaped deformation bar 8 and the fourth arc-shaped deformation bar 9 are arranged at the center position of the left side of the movable end 2, and the two first arc-shaped deformation bars 5 are respectively arranged on the front and rear sides of the left side of the movable end 2, so that the second arc-shaped deformation bar 6 is correspondingly arranged on the outside of the first arc-shaped deformation bar 5, so that the movable end 2 can achieve long-term contact and conduction with the movable electrode 13 when moving in multiple directions.

[0035] Furthermore, Figure 2 and Figure 4 As shown, in order to further increase the inertia of the second arc-shaped deformation bar 6 and the fourth arc-shaped deformation bar 9 during use, in this embodiment, the second arc-shaped deformation bar 6 and the fourth arc-shaped deformation bar 9 are gradually expanded outward from the head end to the tail end; at the same time, the contact conductive portion in this embodiment includes a contact plane 7 arranged at the tail end of the second arc-shaped deformation bar 6 and the fourth arc-shaped deformation bar 9 for increasing the contact area, and then the contact conductive area with the active electrode 13 is increased through the contact plane 7, so that the vibration sensor in this embodiment is more stable to use and more sensitive to triggering.

[0036] Furthermore, Figure 2 As shown, the movable end 2 in this embodiment includes a main body 10 connected to the connecting part 3 and a process part 11 protruding outward from the main body 10 for connecting the extended conductive member. Since the vibration connecting component in this application is formed by punching out a metal sheet, the two first arc-shaped deformation strips 5 are respectively arranged on the front and rear sides of the process part 11, which is more convenient for the processing and forming of the first arc-shaped deformation strip 5.

[0037] Example 3:

[0038] The difference from the second embodiment is that the structure of the present embodiment in which the movable end 2 moves downward to increase the contact conduction time between the fixed electrode 12 and the movable electrode 13 is different; Figure 7 and 8As shown, the inner sides of the front and rear ends of the electrode connecting portion 14 are provided with contact limiting surfaces 19 corresponding to the tail ends of the second arc-shaped deformation strips 6. Figure 8 As shown, the contact limiting surface 19 is set to be gradually inclined downward from the outside to the inside; specifically, the electrode connecting portion 14 and the bent electrode body 15 in this embodiment are integrated, and the contact limiting surface 19 in this embodiment is correspondingly set on the inner side of the electrode connecting portion 14; then, when the movable end 2 moves downward, the tail end of the second arc-shaped deformation strip 6 first contacts with the inclined contact limiting surface 19, and when the movable end 2 continues to move downward under the action of inertia, the second arc-shaped deformation strip 6 and the first arc-shaped deformation strip 5 are elastically deformed. In this embodiment, since the second arc-shaped strip 6 and the first arc-shaped deformation strip 5 are both designed as horizontal thin plate structures, the outer end of the second arc-shaped strip 6 is limited by the contact limiting surface 19 below, and the first arc-shaped deformation strip 5 and the second arc-shaped strip 6 are elastically deformed. The movable end 2 stops and moves in the opposite direction under the action of inertia and elastic force. During the reverse movement, the elastic deformation of the first arc-shaped deformation bar 5 and the second arc-shaped deformation bar 6 gradually decreases. During this process, the outer end of the second arc-shaped deformation bar 6 is in continuous contact with the contact limit surface 19 until the first arc-shaped deformation bar 5 and the second arc-shaped deformation bar 6 completely rebound and return to a horizontal state. At this time, the outer end of the second arc-shaped deformation bar 6 is disconnected from the contact limit surface 19. From the contact between the outer end of the second arc-shaped deformation bar 6 and the contact limit surface 19 to the separation from the contact limit surface 19, the entire time period is the contact conduction time between the fixed electrode 12 and the movable electrode 13.

[0039] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
