Description

Technical Field

[0001] This invention relates to the field of crystal oscillator damping technology, and more specifically, to a miniature crystal oscillator damper. The invention also relates to a method of using this miniature crystal oscillator damper. Background Technology

[0002] A thermostatic crystal oscillator, or thermostatic crystal resonator for short, is a crystal oscillator that uses a thermostatic bath to keep the temperature of the quartz crystal resonator in the crystal oscillator constant, thereby minimizing the change in the output frequency of the oscillator caused by changes in ambient temperature. Temperature control is usually achieved by using a differential series amplifier composed of a thermistor "bridge".

[0003] Chinese patent application number 202120009204.7 (patent title: A high-heat-dissipation, shock-resistant, constant-temperature crystal oscillator) includes a base block. This base block facilitates effective connection with the upper housing via an adhesive layer and also provides good support for the underlying mechanism. A buffer plate, in conjunction with a movable groove, allows the buffer plate to move effectively within the groove. A support plate, connected and fixed to the lower end of the base block, provides auxiliary support for the lower end of the buffer plate. A connecting rod, effectively connected to the upper wall of the movable groove, and through its movable engagement with the buffer plate, provides good limiting and support for the buffer plate's movement, resulting in good cushioning and shock absorption between the movable groove and the buffer plate. A sliding ball allows for good auxiliary sliding between the buffer plate's sidewall and the inner wall of the movable groove as it moves within the groove. However, this patent relies solely on a spring for shock absorption. The spring itself reciprocates and does not effectively reduce shock; in fact, it may exacerbate vibrations.

[0004] Therefore, it is necessary to develop a miniature crystal oscillator that can effectively reduce the vibration of crystal oscillators. Summary of the Invention

[0005] The primary objective of this invention is to overcome the shortcomings of the aforementioned background technology and to provide a crystal oscillator miniature vibration damper.

[0012] In the above technical solution, the two dampers are, from left to right, a left damper and a right damper, and the two piston cylinders are, from left to right, a left piston cylinder and a right piston cylinder.

[0013] In the above technical solution, a first annular tube and a second annular tube are provided inside the buffer plate;

[0014] The damping cavity is enclosed by the heat exchange cavity; the top side of the heat exchange cavity of the left damper is connected to the first pipe, and the bottom side is connected to the second pipe; the top side of the heat exchange cavity of the right damper is connected to the third pipe, and the bottom side is connected to the fourth pipe; the bottom of the left piston cylinder is connected to the fifth pipe; the bottom of the right piston cylinder is connected to the sixth pipe.

[0015] The first, third, and fifth pipes are all connected to the first annular pipe; the second, fourth, and sixth pipes are all connected to the second annular pipe.

[0016] In the above technical solution, a heat dissipation box is provided in the frame. The heat dissipation box includes a first connecting pipe located on the left side of the heat dissipation box, a second connecting pipe located on the left side of the heat dissipation box, and a heat exchange pipe located inside the heat dissipation box. One end of the heat exchange pipe is connected to the first connecting pipe, and the other end is connected to the second connecting pipe.

[0023] In the above technical solution, a semiconductor cooling chip is provided on the outside of the heat dissipation box.

[0024] To achieve the second objective mentioned above, the technical solution of the present invention is as follows: a method for using a crystal oscillator miniature vibration damper, characterized by comprising the following steps:

[0025] Step 1: Install the crystal oscillator inside the housing;

[0026] Step 2: When the crystal oscillator is vibrated, the base plate applies pressure to the first and second buffer springs, causing the first and second buffer springs to contract. The base plate then pushes the first piston rod and the first piston block downwards in sequence. The damping fluid in the damping chamber dampens the first piston block, which in turn pushes the first piston rod upwards. The first and second buffer springs then push the base plate back to its original position, thus achieving vibration reduction for the crystal oscillator.

[0027] Step 3: When the crystal oscillator is vibrated, the base plate applies pressure to the first and second buffer springs. The base plate then pushes the second piston rod and the second piston block of the left piston cylinder downwards in sequence. The heat exchange liquid in the left piston cylinder is discharged into the first annular tube through the fifth pipe. This allows the heat exchange liquid inside the first annular tube to enter the heat exchange chamber of the left damper through the first pipe. The heat exchange liquid inside the first annular tube enters the heat exchange chamber of the right damper through the third pipe. The heat exchange liquid exchanges heat with the damping liquid in the damping chamber.

[0028] Step 4: When the crystal oscillator is vibrated, the base plate applies pressure to the first and second buffer springs. The base plate then pushes the second piston rod and the second piston block of the right piston cylinder downwards in sequence. The heat exchange liquid in the right piston cylinder is discharged into the second connecting pipe through the eighth pipe. The heat exchange liquid enters the heat exchange tube through the second connecting pipe. The temperature of the heat exchange liquid is conducted to the conductive liquid inside the heat sink. The heat of the conductive liquid is conducted to the heat dissipation fins through the heat conduction plate and heat conduction column. The heat is then dissipated through the heat dissipation fins.

[0029] Step 5: When the first and second buffer springs push the base plate upward;

[0030] The base plate drives the second piston rod and the second piston block of the left piston cylinder to move upward, and the heat exchange liquid in the heat exchange tube is drawn into the left piston cylinder through the first connecting pipe and the seventh pipe in sequence.

[0031] At the same time, the base plate drives the second piston rod and the second piston block of the right piston cylinder to move upward. The heat exchange liquid in the heat exchange chamber of the left damper is drawn into the second annular tube through the second pipe. The heat exchange liquid in the heat exchange chamber of the right damper is drawn into the second annular tube through the fourth pipe. The heat exchange liquid in the second annular tube is drawn into the right piston cylinder through the sixth pipe.

[0032] Step 6: Repeat steps 2-5 to complete the damping of the crystal oscillator and the heat exchange of the damping fluid.

[0033] In the above technical solution, in step 4, the semiconductor cooling chip dissipates heat from the conductive liquid.

[0034] Compared with the prior art, the present invention has the following advantages:

[0035] 1) In this invention, the crystal oscillator is installed inside the frame, and the frame is limited by an adhesive layer. When the crystal oscillator is vibrated, the base plate applies pressure to the first buffer spring and the second buffer spring. The first buffer spring and the second buffer spring contract, and the base plate pushes the first piston rod and the first piston block downward in sequence. The damping fluid in the damping cavity dampens the first piston block. The first piston block pushes the first piston rod upward. The first buffer spring and the second buffer spring push the base plate to reset, thereby achieving vibration reduction of the crystal oscillator and ensuring the vibration reduction effect of the crystal oscillator.

[0036] 2) This invention dissipates heat through a heat dissipation box and a heat exchange fluid, and exchanges heat with the damping fluid inside the damping cavity through the heat exchange fluid, so as to keep the oil seal temperature within a safe range and prevent problems such as excessive foaming and oil leakage.

[0064] A method of using a crystal oscillator miniature vibration damper, characterized by comprising the following steps:

[0065] Step 1: Install the crystal oscillator inside the housing 3;

[0066] Step 2: When the crystal oscillator is vibrated, the base plate 1 applies pressure to the first buffer spring 11 and the second buffer spring 53. The first buffer spring 11 and the second buffer spring 53 contract, and the base plate 1 pushes the first piston rod 43 and the first piston block 42 downward in sequence. The damping fluid in the damping cavity 41 dampens the first piston block 42. The first piston block 42 pushes the first piston rod 43 upward. The first buffer spring 11 and the second buffer spring 53 push the base plate 1 to reset, thereby achieving vibration reduction of the crystal oscillator.

[0067] Step 3: When the crystal oscillator is vibrated, the base plate 1 applies pressure to the first buffer spring 11 and the second buffer spring 53. The base plate 1 then pushes the second piston rod 52 and the second piston block 51 of the left piston cylinder 54 downward in sequence.

The heat exchange liquid inside the first annular tube 21 enters the heat exchange chamber 46 of the right damper 45 through the third pipe 63. The heat exchange liquid exchanges heat with the damping liquid in the damping chamber 41.

[0068] Step 4: When the crystal oscillator is vibrated, the base plate 1 applies pressure to the first buffer spring 11 and the second buffer spring 53. The base plate 1 then pushes the second piston rod 52 and the second piston block 51 of the right piston cylinder 55 downward in sequence. The heat exchange liquid in the right piston cylinder 55 is discharged into the second connecting pipe 312 through the eighth pipe 68. The heat exchange liquid enters the heat exchange tube 313 through the second connecting pipe 312. The temperature of the heat exchange liquid is conducted to the conductive liquid inside the heat dissipation box 31. The heat of the conductive liquid is conducted to the heat dissipation fins 315 through the heat conduction plate 314 and the heat conduction column 3141. The heat is then dissipated through the heat dissipation fins 315.

[0069] Step 5: When the first buffer spring 11 and the second buffer spring 53 push the base plate 1 upward;

[0070] The base plate 1 drives the second piston rod 52 and the second piston block 51 of the left piston cylinder 54 to move upward, and the heat exchange liquid in the heat exchange tube 313 is sequentially drawn into the left piston cylinder 54 through the first connecting pipe 311 and the seventh pipe 67.

The heat exchange liquid in the heat exchange chamber 46 of the left damper 44 is drawn into the second annular pipe 22 through the second pipe 62. The heat exchange liquid in the heat exchange chamber 46 of the right damper 45 is drawn into the second annular pipe 22 through the fourth pipe 64. The heat exchange liquid in the second annular pipe 22 is drawn into the right piston cylinder 55 through the sixth pipe 66.

[0072] Step 6: Repeat steps 2-5 to complete the vibration damping of the crystal oscillator and the heat exchange of the damping fluid.

[0073] In step 4, the semiconductor cooling chip 32 dissipates heat from the conductive liquid.

[0074] Example 1

[0075] A method of using a crystal oscillator miniature vibration damper, characterized by comprising the following steps:

[0076] The crystal oscillator is installed inside the housing 3;

[0077] When the crystal oscillator is vibrated, the base plate 1 applies pressure to the first buffer spring 11 and the second buffer spring 53:

[0078] The first buffer spring 11 and the second buffer spring 53 contract, and the base plate 1 pushes the first piston rod 43 and the first piston block 42 downward in sequence. The damping fluid in the damping cavity 41 dampens the first piston block 42. The first piston block 42 pushes the first piston rod 43 upward, and the first buffer spring 11 and the second buffer spring 53 push the base plate 1 to reset, thereby achieving vibration reduction of the crystal oscillator.

[0079] At the same time, the base plate 1 pushes the second piston rod 52 and the second piston block 51 of the left piston cylinder 54 downward in sequence. The heat exchange liquid in the left piston cylinder 54 is discharged into the first annular pipe 21 through the fifth pipe 65, so that the heat exchange liquid inside the first annular pipe 21 enters the heat exchange chamber 46 of the left damper 44 through the first pipe 61. The heat exchange liquid inside the first annular pipe 21 enters the heat exchange chamber 46 of the right damper 45 through the third pipe 63. The heat exchange liquid exchanges heat with the damping liquid in the damping chamber 41.

[0080] Simultaneously, the base plate 1 sequentially pushes the second piston rod 52 and the second piston block 51 of the right piston cylinder 55 downwards. The heat exchange liquid in the right piston cylinder 55 is discharged into the second connecting pipe 312 through the eighth pipe 68. The heat exchange liquid enters the heat exchange tube 313 through the second connecting pipe 312. The temperature of the heat exchange liquid is conducted to the conductive liquid inside the heat dissipation box 31. The heat of the conductive liquid is conducted to the heat dissipation fins 315 through the heat conduction plate 314 and the heat conduction column 3141. The heat is then dissipated through the heat dissipation fins 315.

[0081] When the first buffer spring 11 and the second buffer spring 53 push the base plate 1 upward:

[0082] The base plate 1 drives the second piston rod 52 and the second piston block 51 of the left piston cylinder 54 to move upward, and the heat exchange liquid in the heat exchange tube 313 is sequentially drawn into the left piston cylinder 54 through the first connecting pipe 311 and the seventh pipe 67.

[0083] Simultaneously, the base plate 1 drives the second piston rod 52 and the second piston block 51 of the right piston cylinder 55 to move upward. The heat exchange fluid in the heat exchange chamber 46 of the left damper 44 is drawn into the second annular pipe 22 through the second pipe 62. The heat exchange fluid in the heat exchange chamber 46 of the right damper 45 is drawn into the second annular pipe 22 through the fourth pipe 64. The heat exchange fluid in the second annular pipe 22 is drawn into the right piston cylinder 55 through the sixth pipe 66. This completes the damping of the crystal oscillator and the heat exchange of the damping fluid.

[0084] Example 2

[0085] The difference between this embodiment and embodiment 1 is that a semiconductor cooling chip 32 is provided on the outside of the heat sink 31. When the heat exchange liquid in the heat exchange tube 313 is dissipated, the heat exchange liquid in the heat exchange tube 313 conducts heat to the conductive liquid in the heat sink 31. The semiconductor cooling chip 32 cools the conductive liquid in the heat sink 31, thereby increasing the rate at which the temperature of the heat exchange liquid is reduced.
