[0040] In the technical field of electronic products, after a user touches a touch panel, a piezoelectric module is often used to provide feedback to the user's touch. In existing piezoelectric modules, the piezoelectric driver is directly mounted on a steel sheet, and the piezoelectric ceramic material used in the piezoelectric driver is a rigid and brittle material. The steel sheet has a strong restraining effect on the piezoelectric driver. In key touch feedback applications, vibration usually causes breakage and failure.
[0041] In order to solve the above problems, the utility model provides a vibration component mounting plate, a vibration assembly and a piezoelectric module.

Figure 3 for Figure 1 A top view of a vibrating assembly in FIG. Figure 4 for Figure 1 A three-dimensional schematic diagram of another perspective of the vibration component in the embodiment.
[0042] See also Figures 1 to 4The vibration component mounting plate 10 includes a main body, including: a vibration section 20, two mounting sections 30 and two connecting sections 40. The vibration section 20 is used for positioning and mounting the vibration component 50 so as to vibrate with the vibration of the vibration component 50. The mounting section 30 is used for mounting to an electronic product, and the two mounting sections 30 are respectively arranged at both ends of the vibration section 20. The two connecting sections 40 are respectively connected to the two ends of the vibration section 20 and the two mounting sections 30, and the minimum strength of the connecting section 40 is less than the minimum strength of the mounting section 30 and the vibration section 20. In the technical solution provided by the utility model, by setting the connecting section 40, the minimum strength of the connecting section 40 is set to be less than the minimum strength of the mounting section 30 and the vibration section 20, so that when the vibration component 50 vibrates, the vibration section 20 can vibrate with the vibration component 50 to reduce the constraint on the vibration component 50, and avoid the vibration component 50 from being broken and failing under the constraint of the vibration component mounting plate 10.
[0043] It should be noted that the minimum strength of the connecting section 40 is smaller than the minimum strength of the mounting section 30 and the vibration section 20. The connecting section 40, the mounting section 30 and the vibration section 20 may be made of different materials to form different strengths. The size of the connecting section 40 may be smaller than the size of the mounting section 30 and the vibration section 20. For example, the width or thickness of the connecting section 40 is smaller than the width or thickness of the mounting section 30 and the vibration section 20, and so on. This is not limited here.
[0044] The specific implementation form of the vibration component mounting plate 10 is not limited, and it can be in the form of a steel plate, or other metal plates, such as an aluminum plate, or a high-toughness plastic material, etc., which is not limited here.
[0045] The specific implementation form of the vibration element 50 is not limited, and it can be a piezoelectric driver, or other components that can vibrate, etc., which is not limited here.
[0046] The specific installation position of the installation section 30 is not limited, and can be any position of the electronic product. In one embodiment, the installation section 30 is installed on the touch panel of the electronic product, so that the vibration member 50 can generate vibration after the user touches the touch panel to provide feedback to the user. The installation method of the installation section 30 is not limited, and can be fixed installation, limited installation, movable installation, etc., which are not limited here.
[0047] Considering that different materials are used to make the connecting section 40 and the mounting section 30 or the vibration section 20 , the manufacturing process is more complicated. Therefore, in one embodiment, the cross-sectional area of the connecting section 40 is smaller than the cross-sectional area of the mounting section 30 and the vibration section 20 .
[0048] In the technical solution of the present embodiment, by setting the cross-sectional area of the connecting section 40 to be smaller than the cross-sectional area of the mounting section 30 and the vibration section 20, the strength of the connecting section 40 can be made smaller than the strength of the mounting section 30 and the vibration section 20. At this time, the vibration section 20, the mounting section 30, and the connecting section 40 can be made of the same material, and can be manufactured in an integrated molding manner during the manufacturing process, which greatly reduces the difficulty of production.
[0049] Specifically, the cross-sectional area is smaller than the cross-sectional area of the mounting section 30 and the vibration section 20. The thickness of the connecting section 40 may be smaller than the thickness of the mounting section 30 and the vibration section 20, or the width of the connecting section 40 may be smaller than the width of the mounting section 30 and the vibration section 20, and so on. This is not limited here.
[0050] It can be understood that the smaller the cross-sectional area of the connecting section 40 is, the smaller the corresponding intensity is. Under the same vibration of the vibrating member 50, the larger the amplitude of the vibrating section 20 and the connecting section 40 is. Therefore, in order to enhance the amplitude of the vibrating member 50 and improve the vibration, the cross-sectional area of the connecting section 40 first decreases and then increases in the direction away from the vibration section 20. With this arrangement, the amplitude of the connecting section 40 first decreases in the direction away from the vibration section 20, thereby reducing the cross-sectional area at the connection between the mounting section 30 and the vibration section 20, thereby increasing the amplitude of the vibration section 20, improving the vibration, and providing the user with clearer feedback, and then decreasing. After the amplitude reaches a peak value, the amplitude is reduced to avoid slowing down the amplitude transmitted to the mounting section 30, thereby isolating the mounting section 30 from vibration.
[0051] It should be noted that the cross-section decreases first and then increases, the width of the connecting section 40 may decrease first and then increase, the thickness of the connecting section 40 may decrease first and then increase, the width and thickness of the connecting section 40 may decrease first and then increase at the same time, and so on, which is not limited here.
[0052] Furthermore, the reduction and increase of the cross section may be abrupt, that is, a sudden reduction in sections, or gradual, that is, a gradual reduction first and then a gradual increase. In one embodiment, the cross section first gradually decreases and then increases, thereby avoiding stress concentration and preventing the connection section 40 from breaking at the smallest cross section due to a sudden change in amplitude.
[0053] Furthermore, since the direction of vibration is the thickness direction of the main body, if the thickness of the connecting section 40 is reduced, it is easy to break or bend. Therefore, in an embodiment, the width of the connecting section 40 first decreases and then increases in the direction away from the vibration section 20. Compared with the solution of reducing the thickness, reducing the width of the connecting section 40 will not affect the strength in the thickness direction, thereby ensuring the toughness of the connecting section 40 and reducing the possibility of breakage.
[0054] At the same time, the connecting section 40 includes a first connecting section 41 and a second connecting section 42 which are sequentially arranged in a direction away from the vibration section 20, wherein: the cross-sectional area of the first connecting section 41 is gradually reduced in a direction away from the vibration part; the cross-sectional area of the second connecting section 42 is gradually increased in a direction away from the vibration part.
[0055] In the solution of this embodiment, by setting the first connecting section 41, the constraint of the mounting section 30 on the vibration section 20 can be reduced, thereby improving the vibration sensation of the vibration assembly 100, and the cross-sectional area thereof is gradually reduced, which can avoid the influence of stress concentration and reduce the possibility of fracture. By setting the second connecting section 42, the cross-sectional area thereof is gradually increased in the direction away from the vibration part, thereby gradually reducing the amplitude transmitted by the first connecting section 41, isolating the first connecting section 41 from vibration, and weakening the influence of the vibration member 50 on the mounting section 30.
[0056] Furthermore, in order to improve the vibration isolation effect, the second connecting section 42 is provided with a reinforcing rib 43. In the solution of this embodiment, the second connecting section 42 is provided with a reinforcing rib 43, so as to improve the strength of the second connecting section 42, thereby improving the vibration isolation effect of the second connecting section 42.
[0057] It should be noted that the setting position of the reinforcing rib 43 is not limited, and it can be located on one side in the width direction of the second connecting segment 42, or on one side in the thickness direction of the second connecting segment 42, or there can be multiple reinforcing ribs 43, some of which are located on one side in the width direction of the second connecting segment 42, and some of which are located on one side in the thickness direction of the second connecting segment 42, and so on. There is no limitation on this.
[0058] The specific shape of the reinforcing rib 43 is not limited, and it can be partially set on the second connecting section 42, or completely set in the length direction of the second connecting section 42, or it can be in a rectangular shape, or it can be in a cylindrical shape, etc., which is not limited here.
[0059] Furthermore, the maximum strength of the second connecting section 42 may be greater than the maximum strength of the mounting section 30 , or may be less than the maximum strength of the mounting section 30 , which is not limited herein. In one embodiment, the maximum strength of the second connecting section 42 is greater than the maximum strength of the mounting section 30 .
[0060] In the technical solution of this embodiment, the maximum strength of the second connecting section 42 is greater than the maximum strength of the mounting section 30. On the one hand, it can better block the vibration transmitted by the first connecting section 41, so that the amplitude at the mounting section 30 is smaller. On the other hand, during the falling process, the strengths of the first connecting section 41, the second connecting section 42 and the mounting section 30 follow a weak-strong-weak change. If the strengths are all weakened, that is, a weak-weak-weak design, during the falling process, the vibration component mounting plate 10 will undergo a large deformation, and the inertial force will react on the vibration component 50 to smash the product. The middle second connecting section 42 is reinforced, and the maximum strength of the second connecting section 42 is greater than the maximum strength of the mounting section 30, thereby reducing the deformation caused by the inertial force, thereby protecting the vibration component 50 during the falling process.
[0061] Considering that the vibration direction of the main body is the thickness direction, the reinforcing rib 43 is arranged on one side of the second connecting section 42 in the thickness direction. Such a setting can effectively improve the strength of the second connecting section 42 in the thickness direction, and its vibration isolation effect is better than the scheme set in the width direction.
[0062] Furthermore, two reinforcing ribs 43 are arranged at intervals in the width direction of the second connecting section 42, and the two reinforcing ribs 43 and the second connecting section 42 together form a U-shaped beam structure. In the technical solution of this embodiment, two reinforcing ribs 43 are arranged at intervals in the width direction of the second connecting section 42, and the two reinforcing ribs 43 and the second connecting section 42 can form a U-shaped beam. The U-shaped beam structure is a common beam structure, and its main characteristics are as follows. The U-shaped beam structure has high rigidity and strength. Because it adopts a U-shaped cross-sectional shape, it can better withstand bending and shear forces when subjected to force, thereby improving the overall rigidity and strength, which makes the beam structure show good performance when carrying human spans and human loads.
[0063] Therefore, the two reinforcing ribs 43 and the second connecting section 42 can form a U-shaped beam, which can improve the overall rigidity and strength, further improve the vibration isolation effect, and weaken the impact of the vibration of the vibration member 50 on the installation section 30.
[0064] The specific installation form of the mounting section 30 is not limited, and can be fixed installation, such as directly screwing or bonding the mounting section 30, or movable installation, such as setting a boss 60, and movably mounting the mounting hole 31 of the mounting section 30 on the boss 60. Of course, it can also be a floating installation, such as using two elastic members to press up and down along the thickness direction of the mounting section 30, etc., which is not limited here. In the present embodiment, the main body is located at the mounting section 30 and has a mounting hole 31 passing through it along its thickness direction, so that the mounting hole 31 can be set on the side of the boss 60 by setting the mounting hole 31. At this time, the boss 60 can limit the vibration component mounting plate 10 in the horizontal direction, but not in the thickness direction of the vibration component mounting plate 10, so that it can be movable along its thickness direction. On the one hand, it can enhance the vibration feeling, and on the other hand, it can play a role in fall buffering when falling.
[0065] Furthermore, in order to enhance the limiting effect on the main body in the planar direction, a plurality of limiting protrusions 32 are provided on the hole wall of the mounting hole 31, and the plurality of limiting protrusions 32 are used to abut against the peripheral side of the boss 60. With such an arrangement, the plurality of limiting protrusions 32 abut against the peripheral side of the boss 60 of the electronic product, so that the plurality of limiting protrusions 32 can be clamped with the boss 60 of the electronic product to enhance the limiting effect. Moreover, since the plurality of limiting protrusions 32 clamp the peripheral side of the boss 60 of the electronic product, the boss 60 will not have too much limiting effect on the thickness direction of the vibration component mounting plate 10, thereby not completely fixing the two ends of the main body, and can play a fall buffering role in the vertical thickness direction.
[0066] It can be understood that one end of the limiting protrusion 32 is fixedly set on the hole wall of the mounting hole 31, therefore, it is actually a cantilever structure, and accordingly, the longer the length of the limiting protrusion 32, the greater the vibration amplitude generated at the end in the direction away from the mounting hole 31, therefore, in the direction close to the vibration section 20, the lengths of multiple limiting protrusions 32 increase successively, and correspondingly, the closer to the vibration section 20, the longer the length of the limiting protrusion 32, which can increase the amplitude of the vibration section 20 and enhance the vibration feeling, while the length of the limiting protrusion 32 in the direction away from the vibration section 20 is reduced, which can improve the vibration isolation effect, which can not only meet the release of the vibration energy of the pressure vibration part 50, but also ensure the double shock absorption of the vibration assembly 100 when it is anti-falling.
[0067] To achieve the above-mentioned purpose, the present application also proposes a vibration component 100, including a vibration member mounting plate 10 and a vibration member 50. The vibration member mounting plate 10 includes a main body, including: a vibration section 20, two mounting sections 30 and two connecting sections 40. The vibration section 20 is used for positioning and installing the vibration member 50 so as to vibrate with the vibration of the vibration member 50. The mounting section 30 is used for installation to an electronic product, and the two mounting sections 30 are respectively arranged at both ends of the vibration section 20. The two connecting sections 40 are respectively connected to the two ends of the vibration section 20 and the two mounting sections 30. The strength of the connecting section 40 is less than the strength of the mounting section 30 and the vibration section 20. The vibration member 50 is installed on the vibration section 20 of the main body of the vibration member mounting plate 10. In the technical solution provided by the utility model, by setting the connecting section 40, the strength of the connecting section 40 is set to be smaller than the strength of the mounting section 30 and the vibration section 20, so that when the vibration member 50 vibrates, the vibration section 20 can vibrate along with the vibration member 50 to reduce the constraint on the vibration member 50, thereby avoiding the vibration member 50 from being broken and failing under the constraint of the vibration member mounting plate 10.
[0068] The specific implementation form of the vibration element 50 is not limited, and it can be a piezoelectric driver, or other components that can vibrate, etc., which is not limited here. In one embodiment, the vibration element 50 includes a piezoelectric driver.
[0069] To achieve the above objectives, the present application also proposes a piezoelectric module, including the vibration component 100 as described above.
[0070] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
