Description

Technical Field

[0001] This utility model relates to the field of shock absorption devices, and in particular to a shock absorption support device for the interior equipment of rail vehicles. Background Technology

[0002] Rail vehicles include public transportation such as trains, high-speed trains, and subways. Since rail vehicles usually run on rails, they generate significant vibrations when turning or changing tracks. Therefore, vibration damping devices are usually added to the electrical and other equipment inside the rail vehicles to reduce the vibrations they experience during operation. For example, a vibration damping support device for a train air conditioning compressor (publication announcement number CN212454752U) is disclosed on the China Patent Network. This type of vibration damping support device applies vertical vibration damping to the compressor through the action of multiple second springs between the mounting plate and the fixed pier, and applies lateral vibration damping to the compressor by installing a first spring in a deep groove.

[0003] However, the aforementioned disclosed patents and existing market-used shock-absorbing support devices still have some shortcomings: While existing methods using horizontally and vertically arranged spring combinations to achieve horizontal and vertical shock absorption provide good shock absorption support, their support is typically limited to a single force direction, resulting in a relatively singular shock absorption force and an inability to adapt to shock absorption from different directions. Therefore, those skilled in the art have provided a shock-absorbing support device for railway vehicle interior equipment to address the problems mentioned in the background art. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a shock-absorbing support device for the interior equipment of rail vehicles, which solves the problem that the existing shock-absorbing support devices mentioned in the background technology have relatively limited and singular shock-absorbing performance.

[0006] As a further technical solution of this utility model: the pneumatic rods are set in three groups, with two in each group, and the three groups of pneumatic rods are arranged in a star-triangle pattern between the bottom support frame and the shock-absorbing fixture.

[0009] As a further technical solution of this utility model: the pneumatic rod is fitted with a shock-absorbing spring along its extension and retraction direction, and the cylinder body of the pneumatic rod is provided with a threaded sleeve, on which a knob for tightening the shock-absorbing spring is screwed.

[0010] As a further technical solution of this utility model: the positioning screw is provided in multiple sets, and the multiple sets of positioning screws are arranged circumferentially along the support frame.

[0011] As a further technical solution of this utility model: the support frame is provided with a shock-absorbing rubber pad through the positioning screw, and the shock-absorbing rubber pad is made of natural rubber material.

[0012] This utility model provides a shock-absorbing support device for the interior equipment of rail vehicles, which has the following advantages compared with the prior art:

[0013] The vibration damping support device for rail vehicles designed in this paper is based on a combination of a bottom support frame and a top support frame as a vibration damping support platform. Under the intermediate support of the vibration damping fixture, it is set into a hexagonal support state, which not only provides circumferential vibration damping support, but also has universal force deformation characteristics, so as to provide vibration damping support in any direction and withstand vibration forces from all directions, thus achieving a good vibration damping support function.
