Obviously, the described embodiments are some of the embodiments of the present application, not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.
[0043] In addition, the term "and / or" in this document merely describes an associated relationship between associated objects, which means that there can be three relationships, for example, A and / or B can represent three cases of A alone, A and B together, and B alone. In addition, the character " / " in this document generally represents an "or" relationship between the front and rear associated objects.
[0044] The application provides a shockproof system and a shockproof display cabinet, which are beneficial to the shockproof of photos placed naturally without support and restraint.
[0045] In a first aspect, the embodiments of the application disclose a shockproof system.
[0046] Referring to Figure 1 The shockproof system comprises a display platform, a connecting platform and a bearing platform which are parallel to each other, the connecting platform is slidably connected with the display platform and the bearing platform, the relative sliding track of the connecting platform and the display platform is perpendicular to the relative sliding track of the connecting platform and the bearing platform, and both of the relative sliding tracks are parallel to the bearing platform.
[0047] Specifically, the display platform, the connecting platform and the bearing platform are rectangular plates with the same size, the two long edges of the display platform are slidably connected with the two long edges of the connecting platform, and the sliding tracks are along the two long edges, respectively, the two short edges of the connecting platform are slidably connected with the two short edges of the bearing platform, and the sliding tracks are along the two short edges, respectively, so that the display platform can slide freely on a plane relative to the bearing platform (of course, limited by the length of the sliding track). This structure can effectively decompose and unload the shock borne by the bearing platform, so as to protect the exhibits displayed on the display platform as much as possible.
[0048] The sliding connection is realized by a gas-magnetic double-control track spring structure.
[0049] Referring to Figure 2 The gas-magnetic double-control track spring structure comprises a sliding rail and a sliding block, the sliding block is a permanent magnet, and the N pole and the S pole of the sliding block point to the two ends of the sliding rail, respectively, one permanent magnet repelling the sliding block is arranged at each end of the sliding rail, and one controllable electromagnet attracting or repelling the sliding block is arranged at each end of the sliding rail, respectively, the N pole and the S pole of the sliding block are further connected to the two ends of the sliding rail through a controllable gas spring, and the extension direction of the controllable gas spring is parallel to the sliding rail.
[0050] Figure 2The principle diagram of the air-magnetic double-control track spring structure is shown in the figure, and the air-magnetic double-control track spring structure connecting the connecting platform and the bearing platform is taken as an example for illustration. The slide rail frame is fixedly connected to the connecting platform, and the sliding block is fixedly connected to the display platform. The slide rail is in the shape of a rod, and the sliding block is a cylindrical permanent magnet with a sliding hole. The sliding block is coaxial with the sliding hole, and the sliding hole is in clearance fit with the slide rail to achieve sliding connection. The two ends of the sliding block are N-pole and S-pole respectively. Two electromagnets are fixedly arranged at the two ends of the slide rail frame respectively, and are arranged higher than the slide rail and lower than the slide rail respectively. The magnetic force directions of the two electromagnets are along the slide rail direction, so as to attract or repel the sliding block. Two permanent magnets are also fixedly arranged at the two ends of the slide rail frame respectively, and the magnetic force directions are along the slide rail direction to repel the sliding block. The controllable gas spring (shown in the form of a spring line in the figure, and the specific controllable gas spring can refer to the structure of the pneumatic telescopic rod. The controllable gas spring is filled with compressible gas to have elasticity, and the damping coefficient of the controllable gas spring can be changed by filling and discharging gas) is connected to one end of the sliding block and the other end of the slide rail frame, so that the two controllable gas springs can provide elastic force for the sliding block.
[0051] Based on the above, the cooperation structure of the electromagnet, the sliding block and the controllable gas spring makes the elasticity of the sliding block flexible and controllable, and the basic damping coefficient of the permanent magnet and the controllable gas spring can also provide basic elastic force for the sliding block, so that the shockproof system can have better performance, and the shockproof performance can be flexibly adjusted according to different requirements of different exhibits, and the usability is higher.
[0052] Referring to Figure 2 and Figure 3 , further, the shockproof system further comprises an air control subsystem and a control subsystem;
[0053] The air control subsystem is connected to the controllable gas spring, and is used to charge or discharge the gas spring to change the damping coefficient of the gas spring. The control subsystem is connected to the electromagnet, and is used to control the magnetic force size and direction of the electromagnet.
[0054] Specifically, the air control subsystem can include (not shown in the figure) a compressed gas source, a first gas path connecting the compressed gas source and the controllable gas spring, a charging valve arranged in the first gas path, a second gas path connecting the controllable gas spring and the atmosphere, and a discharging valve arranged in the second gas path. The charging valve is opened to charge the controllable gas spring, and the discharging valve is opened to discharge the controllable gas spring, so as to realize the control of the damping coefficient of the controllable gas spring. Of course, in order to facilitate the charging of the compressed gas source, a third gas path connecting the compressed gas source and the charging port and a one-way valve arranged in the third gas path can also be provided. The one-way valve allows the gas to flow from the charging port to the compressed gas source, so as to charge the compressed gas source.
[0055] Further, the shockproof system further comprises three inertial elements respectively arranged on the display platform, the connecting platform and the bearing platform to respectively collect first acceleration data of the display platform, second acceleration data of the connecting platform and third acceleration data of the bearing platform, and the control subsystem is connected with the display platform, the connecting platform and the bearing platform to receive the first acceleration data, the second acceleration data and the third acceleration data.
[0056] Further, the control subsystem is further configured to: pre-acquire a corresponding relationship between the acceleration data and the electromagnet and the controllable gas spring, and pre-set an initial magnetic force of the permanent magnet on the slider and an initial damping coefficient of the controllable gas spring; set the damping coefficient of the controllable gas spring as a specified damping coefficient, and set the magnetic force of the electromagnet as a specified magnetic force size and a specified magnetic force direction; and control the first acceleration and the second acceleration not to exceed the acceleration threshold value by controlling the specified damping coefficient, the specified magnetic force size and the specified magnetic force direction.
[0057] The permanent magnet can provide the slider with basic "magnetic elasticity", and the controllable gas spring in the initial state (when the built-in rated amount of gas) can provide the slider with basic "gas elasticity", both the "magnetic elasticity" and the "gas elasticity" can bring the slider with elastic force, and the farther the slider deviates from the initial position, the greater the elastic force the slider receives. Based on this principle, the electromagnet and the controllable gas spring can be configured according to actual situation requirements, so that the elastic force brought by the "magnetic elasticity" and the "gas elasticity" to the slider is relatively reasonable when shaking. Of course, since the bearing platform is a vibration source relative to the exhibit, a strong monitoring mechanism can also be used, when the acceleration of any one of the connecting platform and the display platform exceeds the acceleration threshold value, it is judged that the exhibit has a risk of falling, and the stiffness of the "magnetic elasticity" and the "gas elasticity" is reduced to reduce the elastic force and reduce the possibility of the exhibit falling.
[0058] Further, the control subsystem is further configured to: acquire the center of gravity position data and the bearing shape data of the exhibit to be displayed; and determine the specified damping coefficient, the specified magnetic force size, the specified magnetic force direction and the acceleration threshold value based on the preset reference table according to the center of gravity position data and the bearing shape data of the exhibit to be displayed.
[0059] Based on the experience of those skilled in the art, the reason for the exhibit to fall is that the center of gravity deviates from the support, that is, when the center of gravity position data of the exhibit is known and its bearing shape data is known, it can be determined under what acceleration the exhibit is prone to fall, and here the relationship between the bearing shape data, the center of gravity position data and the instantaneous acceleration that the exhibit can withstand without falling can be determined based on the experience of those skilled in the art combined with a limited number of experiments, that is, a preset reference table is trained, and in actual use of the shockproof system, the specified damping coefficient, the specified magnetic force size, the specified magnetic force direction and the acceleration threshold value can be automatically determined according to the preset reference table.

[0062] The gas-magnetic double control track spring structure comprises a sliding rail and a sliding block, the sliding block is a permanent magnet and its N-pole and S-pole point to the two ends of the sliding rail respectively, a permanent magnet repelling the sliding block is arranged at each end of the sliding rail, a controllable electromagnet attracting or repelling the sliding block is arranged at each end of the sliding rail, and the N-pole and S-pole of the sliding block are connected to the two ends of the sliding rail through a controllable gas spring, and the extension direction of the controllable gas spring is parallel to the sliding rail.
