Abstract
Description
Technical Field
[0001] The invention relates to the technical field of crystal vibration reduction, in particular to a crystal vibration reduction alloy vibration reduction component and a quartz crystal resonator. Background Art
[0002] Quartz crystal resonator is one of the most commonly used electronic components in electronic circuits. It is composed of crystal and peripheral components. Crystal is made by cutting a thin slice from a quartz crystal in a certain direction, polishing both ends of the slice and coating it with a conductive silver layer, and then connecting electrodes from the silver layer and packaging it. Crystal is a component that can convert electrical energy and mechanical energy into each other. It uses the piezoelectric effect of the crystal, that is, when a voltage is applied to the two poles of the crystal, the crystal will deform. Conversely, if an external force deforms the crystal, the metal sheets on the two poles will generate voltage. When an appropriate alternating voltage is applied to the crystal electrodes, the crystal will generate a resonant frequency that is related to the inclination angle of the quartz bevel, and the frequency is constant. In the resonant state, the crystal can provide stable and accurate single-frequency oscillation to the outside.
[0003] When the crystal works in a vibrating environment, the crystal is affected by external mechanical vibrations, and its shape and size will change. At the same time, mechanical vibrations cause the internal components of the crystal to loosen or shift, resulting in changes in the charge distribution and electric field inside the crystal. These changes are amplified by the amplifier and fed back to the crystal through the feedback network. The crystal output frequency will produce a discrete spectrum and introduce mechanical vibration frequency modulation sidebands, which will cause the stability and accuracy of the crystal output frequency to decrease and worsen the phase noise.
[0004] Since the crystal weighs only about 6g, the vibration-damping structure needs to be made very light.
[0005] Existing patent CN114301417A discloses an upper gold wire braided ring and a lower gold wire braided ring, which clamp the quartz crystal resonator from the front and back sides respectively. Based on the good flexibility of the gold wire braided ring, the vibration and impact resistance of the quartz crystal resonator can be improved. Existing patent CN114301416A discloses that three elastic rings are installed between the quartz wafer and the base, and the three elastic rings are evenly distributed along a circumference of the back side of the quartz wafer for vibration isolation.
[0006] Problems with the above technology: The main existing vibration reduction method: using gold wire braided rings or elastic rings, which do not provide sufficient support for the crystal, and have problems such as unsatisfactory support effect and unstable vibration reduction, and cannot meet the expected indicators. Summary of the invention
[0007] The object of the present invention is to provide a crystal vibration damping alloy vibration reduction component and a quartz crystal resonator to solve the problems existing in the prior art.
[0008] In order to solve the above technical problems, the present invention provides the following technical solutions: a crystal vibration damping alloy damper, the crystal vibration damper comprising a first ring and a second ring, the first ring comprising a first vertex and a second vertex, the second ring comprising a third vertex and a fourth vertex, the first ring and the second ring intersecting with each other, that is, the first vertex of the first ring overlaps with the third vertex of the second ring and the second vertex of the first ring overlaps with the fourth vertex of the second ring; the first ring and the second ring are both made of vibration damping alloy material.

[0015] Furthermore, the crystal vibration damper and the shell, and the crystal vibration damper and the cover are connected by potting glue, and can also be connected by welding or riveting.
[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1.

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0023] Example 1
[0024] like Figure 1 As shown, embodiment 1 discloses a crystal vibration damping alloy damper. The crystal vibration damper 1 comprises a first circular ring 11 and a second circular ring 12 intersecting each other, and the first circular ring 11 and the second circular ring 12 are both made of a vibration damping alloy material.
[0025] Among them, based on practical applications, the first ring 11 includes a first vertex 111 and a second vertex 112, the second ring 12 includes a third vertex 121 and a fourth vertex 122, and the first ring 11 and the second ring 12 intersect each other, that is, the first vertex 111 of the first ring 11 overlaps with the third vertex 121 of the second ring 12, and the second vertex 112 of the first ring 11 overlaps with the fourth vertex 122 of the second ring 12. The diameter of the first ring 11 passing through the center of the circle is greater than the diameter of the second ring 12 passing through the center of the circle. The first ring 11 is fixed outside the second ring 12 and is perpendicular to the second ring 12 at 90 degrees. The two are connected by potting glue, or by other methods, such as welding, riveting, etc.
[0026] The wall thickness of the first ring 11 and the second ring 12 is the same, ranging from 0.1 to 10 mm; the center diameter of the first ring 11 and the second ring 12 ranges from 1 mm to 3 mm. Specifically, the wall thickness of the first ring 11 and the second ring 12 is preferably 0.1 mm, the center diameter of the first ring 11 is preferably 2.2 mm, and the center diameter of the second ring 12 is preferably 2 mm. The lightweight crystal vibration damper 1 is more conducive to the application of crystals in related fields.
[0027] The vibration absorption principle of Example 1 is as follows: The first ring 11 and the second ring 12 made of vibration-damping alloy have the same damping characteristics as rubber and the same strength as structural steel, and can consume the energy generated by vibration through the generation and movement of internal twins to achieve the purpose of vibration reduction. The first ring 11 is used to support between the crystal and the external device and absorb the vibration force transmitted therebetween; the second ring 12 is used to enhance the supporting force of the first ring 11, extend its service life, and further absorb and consume the vibration force.
[0028] Example 2
[0029] like Figure 2-Figure 3 As shown, embodiment 2 discloses a quartz crystal resonator 2, which is applied with a crystal vibration damper 1. Embodiment 2 includes a cover 21, a shell 22 and a crystal 23. The crystal 23 is located in the middle of the shell 22, and the cover 21 covers the upper part of the shell 22. The crystal vibration damper 1 of embodiment 1 is placed between the crystal 23 and the shell 22.
[0030] like Figure 4 As shown, based on actual applications, a crystal vibration damper 1 is provided at the center position of the six faces of the crystal 23, front, back, left, right, top and bottom, to facilitate the absorption of vibration forces in all directions. In addition, the position and number of the crystal vibration damper 1 are not limited to the above. If each direction is a non-central position, there can be multiple crystal vibration dampers. The crystal vibration damper 1 can also be placed in other positions, for example, the crystal vibration damper 1 can be installed at an inclined angle when necessary.
[0031] The crystal vibration damper 1 and the housing 22 , and the crystal vibration damper 1 and the cover 21 are connected by potting glue or other methods, such as welding, riveting, etc.
[0032] The vibration absorption principle of Example 2 is as follows: During operation, the housing 22 vibrates. When the vibration is transmitted to the crystal vibration damper 1, the four crystal vibration dampers 1 in the horizontal direction are laterally squeezed and stretched, and the two crystal vibration dampers 1 above and below the crystal 23 are vertically squeezed and stretched, thereby achieving combined lateral and vertical vibration reduction of the crystal 23. In addition, the material vibration reduction of the vibration-damping alloy itself reduces the vibration of the quartz crystal resonator 2, improves the stability of the output frequency of the quartz crystal resonator 2, and increases the service life of the quartz crystal resonator 2.
