Abstract
Description
Technical Field
[0001] This utility model relates to the field of assisted reproductive technology equipment, and in particular to a bovine in vitro embryo culture environment simulation device. Background Technology
[0002] With the increasing demand for genetic improvement in animal husbandry and the popularization of human assisted reproductive technology, the requirements for the precision of controlling in vitro embryo development conditions are constantly increasing, which necessitates the use of culture environment simulation devices. In practical use, similar culture environment simulation devices still have many defects. For example, traditional culture environment simulation devices use traditional single-stage damping, which is only for a single direction (such as vertical or horizontal), and cannot effectively handle complex composite vibrations under complex working conditions. At the same time, traditional culture environment simulation devices cause reset overshoot and long oscillation time due to rebound hysteresis or damping overload. Therefore, it is necessary to design a bovine in vitro embryo culture environment simulation device. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a bovine in vitro embryo culture environment simulation device.
[0004] This utility model is achieved using the following technical solution: a bovine in vitro embryo culture environment simulation device, comprising a device body assembly, the device body assembly including a simulation device body, a flip-up observation window rotatably connected to the outer surface of the simulation device body, a buffer rod fixedly connected to the bottom of the simulation device body via a bottom mounting base, and bottom connecting bases fixedly connected to both sides of the outer surface of the bottom mounting base, further comprising: The first buffer assembly includes a base plate connected to the bottom of the simulation device body via a first spring damper, a buffer seat fixedly connected to the top of the base plate, a buffer rod provided inside the buffer seat, and a buffer frame fixedly connected to the outer surface of the buffer seat. The third buffer assembly includes a movable block slidably mounted inside the buffer frame, and the movable block is connected to the bottom mounting base via a second connecting rod.
[0005] As a further improvement to the above solution, a bottom mounting bracket is fixedly connected to the bottom of the simulation device body, and a first spring damper is rotatably connected inside the bottom mounting bracket.
[0006] By incorporating the first spring damper into the bottom mounting bracket, the active absorption and energy conversion of horizontal impacts are achieved, avoiding the problem of excessive space occupation by traditional external shock absorption structures and improving the compactness of the device.
[0007] As a further improvement to the above solution, one side of the first spring damper is rotatably connected to the inside of the top mounting bracket, and a base plate is fixedly connected to the bottom of the top mounting bracket.
[0008] Through the above technical solution, the top mounting bracket serves as a fixed fulcrum, forming a stable lever system with the base plate. This allows the first spring damper to generate a bidirectional constraint force when subjected to force, enhancing its ability to suppress lateral swaying.
[0009] As a further improvement to the above solution, a buffer seat is fixedly connected to the center of the top of the base plate, a buffer rod is slidably installed inside the buffer seat, a buffer spring is fixedly connected to the bottom of the buffer rod, and the buffer spring is fixedly connected to the bottom of the inner wall of the buffer seat.
[0010] Through the above technical solution, the buffer rod passes through the buffer seat and is linked with the buffer spring at the bottom to form a vertical elastic support. By utilizing the spring compression deformation to extend the action time of the force, the peak value of the instantaneous acceleration transmitted to the culture dish is effectively reduced.
[0011] As a further improvement to the above solution, the buffer seat is provided with top connecting seats fixedly connected to the top of the base plate on both sides. The outer surface of the top connecting seat is rotatably connected to a first connecting rod, and the side of the first connecting rod away from the top connecting seat is rotatably connected to the outer surface of the moving block.
[0012] Through the above technical solution, the top connecting seat serves as a hinged hub, and the moving block is incorporated into the mechanical feedback loop through the first connecting rod, thereby achieving dynamic compensation for oblique disturbances and avoiding stress concentration caused by unidirectional vibration reduction.
[0013] As a further improvement to the above solution, the movable block is slidably installed inside the buffer frame, and a second spring damper is fixedly connected to the outer surface of the movable block. The side of the second spring damper away from the movable block is fixedly connected to the inner wall of the buffer frame.
[0014] Through the above technical solution, the second spring damper acts directly between the moving block and the buffer frame, providing a controllable frictional resistance torque, accurately regulating the displacement amplitude, and preventing secondary vibration pollution caused by excessive oscillation.
[0015] As a further improvement to the above solution, a second connecting rod is rotatably connected to the side of the outer surface of the movable block away from the first connecting rod, and the side of the second connecting rod away from the movable block is rotatably connected to the outer surface of the bottom connecting seat.
[0016] Through the above technical solution, the second connecting rod passes through the bottom connecting seat to form a closed-loop triangular stable structure, which gathers the dispersed force vectors to the central axis, strengthens the overall torsional stiffness, and ensures the straightness and repeatability of the reset process.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes the series action of a first spring damper, a buffer spring, and a second spring damper to form a gradient damping network in three-dimensional space. Horizontal impacts are preferentially absorbed by the first spring damper and converted into heat energy for dissipation, while vertical loads are guided by the buffer rod to the helical spring for flexible support, extending the force's period of action to reduce peak acceleration. The moving block linkage mechanism, in conjunction with the second damper, achieves vector decomposition of oblique disturbances. This frequency division management strategy enables the system to achieve vibration isolation efficiency superior to traditional single-stage damping in all degrees of freedom, ultimately reducing the vibration amplitude at the culture dish and providing a near-static growth interface for embryonic cell division.
[0018] When the external force disappears, the elastic element group drive system smoothly returns to the initial state. The preloaded reset structure ensures no hysteresis rebound, and the dual damping system precisely controls the motion trajectory, so that each component returns to its orderly position. The flip-up observation window participates in the mechanical balance reconstruction, which maintains the structural rigidity and optimizes the motion inertia. The entire recovery process is natural and smooth, and stable culture conditions are quickly rebuilt, supporting researchers to conduct microscopic observation and operation at any time, and improving experimental efficiency and data reliability.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0022] Example: Please combine Figure 1-5 This embodiment of a bovine in vitro embryo culture environment simulation device includes a device body assembly 1, which includes a simulation device body 101. A flip-up observation window 102 is rotatably connected to the outer surface of the simulation device body 101. A buffer rod 105 is fixedly connected to the bottom of the simulation device body 101 via a bottom mounting base 103. Bottom connecting bases 104 are fixedly connected to both sides of the outer surface of the bottom mounting base 103. The device also includes: The first buffer assembly 2 includes a base plate 201 connected to the bottom of the simulation device body 101 via a first spring damper 203, a buffer seat 204 fixedly connected to the top of the base plate 201, a buffer rod 105 provided inside the buffer seat 204, and a buffer frame 206 fixedly connected to the outer surface of the buffer seat 204. The third buffer assembly 3 includes a movable block 303 that is slidably installed inside the buffer frame 206. The movable block 303 is connected to the bottom mounting base 103 via a second connecting rod 304.
[0023] The bottom of the simulation device body 101 is fixedly connected to a bottom mounting bracket 106, and a first spring damper 203 is rotatably connected inside the bottom mounting bracket 106.
[0024] One side of the first spring damper 203 is rotatably connected to the inside of the top mounting bracket 202, and the bottom of the top mounting bracket 202 is fixedly connected to the base plate 201.
[0025] When an external impact force is applied to the body 101 of the simulation device, its motion tendency is first constrained by the first spring damper 203 connected between the top mounting bracket 202 and the bottom mounting bracket 106. Since this component has compressible characteristics, it generates a reverse force under pressure, converting the kinetic energy in the horizontal direction into spring potential energy for storage.
[0026] A buffer seat 204 is fixedly connected to the center of the top of the base plate 201. A buffer rod 105 is slidably installed inside the buffer seat 204. A buffer spring 205 is fixedly connected to the bottom of the buffer rod 105. The buffer spring 205 is fixedly connected to the bottom of the inner wall of the buffer seat 204.
[0027] The buffer seat 204 has a top connecting seat 301 fixedly connected to the top of the base plate 201 on both sides. The outer surface of the top connecting seat 301 is rotatably connected to the first connecting rod 302. The side of the first connecting rod 302 away from the top connecting seat 301 is rotatably connected to the outer surface of the moving block 303.
[0028] The movable block 303 is slidably installed inside the buffer frame 206. A second spring damper 207 is fixedly connected to the outer surface of the movable block 303. The side of the second spring damper 207 away from the movable block 303 is fixedly connected to the inner wall of the buffer frame 206.
[0029] A second connecting rod 304 is rotatably connected to the side of the outer surface of the movable block 303 away from the first connecting rod 302, and the side of the second connecting rod 304 away from the movable block 303 is rotatably connected to the outer surface of the bottom connecting seat 104.
[0030] During this process, the moving block 303 begins to displace inside the buffer frame 206 due to the force, causing the first connecting rod 302, which is hinged to it, to rotate around the top connecting seat 301. Meanwhile, the second connecting rod 304 on the other side pushes the bottom connecting seat 104 to adjust its posture synchronously. At the same time, the second spring damper 207, which is set between the moving block and the buffer frame, is activated and generates additional resistance torque through its own extension and contraction, forming a double correction to the motion trajectory.
[0031] The implementation principle of the bovine in vitro embryo culture environment simulation device in this application embodiment is as follows: When an external impact force acts on the main body 101 of the simulation device, its movement trend is first constrained by the first spring damper 203 connected between the top mounting frame 202 and the bottom mounting frame 106. Since this component has compressible characteristics, it generates a reverse force under pressure, converting the kinetic energy in the horizontal direction into spring potential energy for storage. At the same time, some energy is consumed through friction of the internal damping medium. As the pressure continues to increase, the buffer rod 105 slides down along the track set by the buffer seat 204, triggering the deformation of the bottom buffer spring 205. At this time, the vertical displacement is converted into the coiling deformation energy of the helical spring, further delaying the transmission speed of the impact. After experiencing the initial impact, the self-recovery characteristics of the system begin to appear. When the external force is removed, the buffer spring 205 pushes the buffer rod back to its original position, causing the entire support structure to rebound. The first spring damper 203 continuously outputs the damping effect during the recovery process to prevent overshoot. The moving block 303 is smoothly reset under the control of the second spring damper 207 to eliminate residual micro-vibrations.
[0032] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
