Description

Technical Field

[0001] The present invention relates to the technical field of shock absorption technology, and in particular to a shock absorption device, a cabin having the shock absorption device, and a mobile vehicle. Background Art

[0002] When special vehicles are operating in the field, the vibration and noise generated by movement will affect the cabin on the special vehicle platform, thereby affecting the on-board equipment inside the cabin, and even affecting the operation of the on-board equipment and the detection of normal data.

[0003] In the related art, conventional shelters typically use shock-absorbing devices to reduce vibration. Specifically, shock absorbers are installed on certain onboard equipment within the cabin that require high stability during operation, thereby reducing the adverse effects of the special vehicle's movement on the onboard equipment. However, this method only applies to the shock absorption of the onboard equipment, and does not significantly improve the overall vibration and noise of the shelter. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a shock absorbing device, a cabin having the shock absorbing device, and a mobile vehicle, so as to reduce the vibration and noise generated by the movement of the cabin body.

[0005] In a first aspect, the present invention provides a shock absorbing device.

[0006] A shock absorbing device comprises: an upper mounting plate, a lower mounting plate, a plurality of first spring shock absorbers, and a plurality of second spring shock absorbers;

[0007] The first spring shock absorber and the second spring shock absorber are both installed between the upper mounting plate and the lower mounting plate. Multiple first spring shock absorbers are respectively located on two opposite sides of the lower mounting plate, and multiple second spring shock absorbers are respectively located on the other opposite sides of the lower mounting plate. The central axis of the first spring shock absorber is parallel to the lower mounting plate.

[0008] By adopting the above technical solution, when the entire shock absorbing device is set on the mobile vehicle and the cabin body is set on the shock absorbing device, if the cabin body vibrates and generates noise due to the movement of the mobile vehicle, the first spring shock absorber and the second spring shock absorber can generate adaptive elastic deformation and reset to achieve the purpose of energy attenuation, and can effectively attenuate the vibration and noise of the cabin body in all directions, thereby helping to reduce the vibration and noise generated by the movement of the cabin body.

[0009] Optionally, the shock absorbing device further comprises: a plurality of side limit plates and a plurality of side lower limit plates;

[0010] The plurality of side limit plates are respectively arranged on opposite sides of the upper mounting plate, and the plurality of side lower limit plates are respectively arranged on opposite sides of the lower mounting plate, and the side limit plates correspond to the side lower limit plates one by one.

[0011] By adopting the above technical solution, when the first spring shock absorber produces elastic deformation, a longitudinal relative displacement will occur between the upper mounting plate and the lower mounting plate. The side limit plate and the side lower limit plate can limit the relative position between the upper mounting plate and the lower mounting plate, thereby providing horizontal load-bearing protection for the first spring shock absorber.

[0012] Optionally, the shock absorbing device further comprises: two front upper limit plates and two front lower limit plates;

[0013] The two front upper limit plates are respectively arranged on the other two opposite sides of the upper mounting plate, and the two front lower limit plates are respectively arranged on the other two opposite sides of the lower mounting plate, and the front upper limit plates and the front lower limit plates correspond to each other one by one.

[0014] By adopting the above technical solution, when the second spring shock absorber produces elastic deformation, a lateral relative displacement will occur between the upper mounting plate and the lower mounting plate. The front upper limit plate and the front lower limit plate can limit the relative position between the upper mounting plate and the lower mounting plate, thereby providing horizontal load protection for the second spring shock absorber.

[0015] Optionally, any one of the first spring shock absorber or the second spring shock absorber comprises: a coil shock absorber spring, a rubber pad and two coil shock absorber spring mounting plates;

[0016] The two spiral shock-absorbing spring mounting plates are respectively mounted on the upper mounting plate and the lower mounting plate, the rubber pad is arranged on the spiral shock-absorbing spring, and the opposite sides of the spiral shock-absorbing spring are respectively passed through and fixed to the upper mounting plate and the lower mounting plate.

[0017] By adopting the above technical solution, the spiral shock-absorbing spring mounting plate can realize the installation of the spiral shock-absorbing spring on the upper mounting plate and the lower mounting plate, and the spiral shock-absorbing spring can reduce the vibration and noise of the cabin body.

[0018] Optionally, the spiral shock-absorbing spring is made of manganese steel spring wire.

[0019] By adopting the above technical solution, the manganese steel spring wire has good elastic deformation effect, strong supporting force and good rebound effect. The use of manganese steel spring wire can effectively ensure the service life of the spiral shock-absorbing spring and can ensure long-term shock-absorbing and noise-reducing effects on the cabin body.

[0020] Optionally, the spacing between the front upper limit plate and the front lower limit plate, and between the side upper limit plate and the side lower limit plate are both set to 20-50 mm.

[0021] By adopting the above technical solution, when the upper and lower mounting plates have a longitudinal relative displacement of 20-50mm, the side limit plates and the side lower limit plates can limit the upper and lower mounting plates, thereby providing horizontal load protection for the first spring shock absorber. Similarly, when the upper and lower mounting plates have a lateral relative displacement of 20-50mm, the side limit plates and the side lower limit plates can also limit the upper and lower mounting plates, thereby providing horizontal load protection for the second spring shock absorber.

[0022] Optionally, the heights of the side limit plates, the side lower limit plates, the front upper limit plates and the front lower limit plates are set to 20-40 mm.

[0023] By adopting the above technical solution, during the process of shock absorption and noise reduction of the cabin body, if the movement of the mobile vehicle causes the deformation range of the elastic deformation of the second spring shock absorber and the first spring shock absorber to become larger, then the upper limit plate will be greatly close to the lower limit plate, which will cause damage to the second spring shock absorber and the first spring shock absorber. By setting the height between the upper limit plate and the lower limit plate to 20-40mm, the upper limit plate can be effectively prevented from being too close to the lower limit plate, thereby achieving vertical load-bearing protection for the second spring shock absorber and the first spring shock absorber.

[0024] In a second aspect, the present invention provides a shelter.

[0025] A shelter comprises a shelter body and a shock absorbing device as described in any one of the first aspects and arranged on the shelter body.

[0026] By adopting the above technical solution and providing a shock-absorbing device under the cabin body, the vibration and noise generated by the movement of the cabin body can be reduced.

[0027] In a third aspect, the present invention provides a mobile vehicle.

[0028] A mobile vehicle comprises the cabin as described in the second aspect.

[0029] By adopting the above technical solution, when the mobile vehicle moves, the on-board equipment inside the cabin can operate better.

[0030] In summary, the present invention has at least the following beneficial technical effects:

[0031] The shock-absorbing device can achieve overall shock absorption of the cabin body with the help of the second spring shock absorber and the first spring shock absorber, and can effectively attenuate the vibration and noise of the cabin body in all directions, achieving better shock absorption effect, thereby protecting the on-board equipment and reducing noise to the greatest extent.
