Description

Technical Field

[0001] The present invention relates to the technical field of electronic information equipment transportation, and in particular to a seismic isolation device for electronic information equipment. Background Art

[0002] During the transportation of large electronic equipment, vibration and impact of the transportation tools will generate great mechanical stress on individual components of the equipment, which may affect the performance of the equipment or even damage the equipment. To avoid this situation, special measures need to be taken for the transportation of such equipment. Vibration reduction devices should be installed at the bottom of the equipment to overcome the impact of vibration caused by earthquakes, road bumps, etc. on the equipment.

[0003] Existing vibration-damping devices often use spring shock absorbers or rubber shock absorbers for buffering vibration in one direction. The spring shock absorbers or rubber shock absorbers for buffering vibration in one direction are effective for vibration in one direction of the vehicle, but have poor buffering effects in other directions.

[0004] During the transportation of electronic equipment, it needs to pass through bumpy sections and flat sections. When the transport vehicle is traveling on the bumpy section, the road surface is uneven and there are obstacles such as potholes and bumps. The vehicle will be subjected to greater impact and vibration when traveling. This impact will directly cause the electronic information equipment to have a larger amplitude in the vertical direction. When the transport vehicle is traveling on the flat section, due to the flat road surface, the amplitude of the electronic information equipment in the vertical direction is relatively smaller than that in the bumpy section. In addition, the speed of the transport vehicle on the flat section is higher than that on the bumpy section. The transport vehicle may encounter emergency braking when traveling on the flat section, resulting in a large speed difference between the front and rear of the vehicle. The amplitude of the electronic information equipment in the horizontal direction may suddenly increase. The existing seismic isolation device for large electronic equipment has a single function and cannot allow the electronic equipment to be adjusted during transportation on flat and bumpy sections, resulting in poor comprehensive shock absorption effect. In view of this, we propose a seismic isolation device for electronic information equipment. Summary of the invention

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention sets a damping mechanism and a spring assembly A which are both connected to the placement table by a ball head, so that the placement table can move in a three-dimensional and all-round manner to buffer all-round vibrations; the transportation process causes the electronic information equipment to vibrate, causing the spring assembly A and the damping mechanism to compress or extend, and the expansion and contraction of the damping mechanism have resistance to consume the force generated by the vibration, thereby providing a seismic isolation effect; and a linkage mechanism is set including four connecting rod assemblies for synchronously adjusting the angles of four damping mechanisms, so that the angle of the damping mechanism can be adjusted according to road conditions, so that the transport vehicle has a good shock-absorbing effect when driving on bumpy roads and flat roads, thereby solving the technical problem that the current seismic isolation device for transporting large electronic information equipment has a single function.

[0027] 2. The present invention provides a specific arrangement of the collar and the spring B, and the gap between the collar and the damper forms a cavity for the following purposes: Figure 8 The spring B shown in the figure is compressed in the limit state. Spring B has a larger deformation space, which improves the elastic recovery force in the limit state and reduces the problem of poor extreme seismic isolation effect caused by the electronic information equipment facing the next large vibration when the driver brakes the vehicle continuously on some continuous downhill slopes before spring B drives the damper to recover. This improves the continuous extreme seismic isolation effect.

[0028] 3. The present invention sets a linkage mechanism so that the slider slides along the slide rail, the linkage block drives the connecting rod A to move synchronously, the guide rod drives the guide block to move in the guide groove, the installation round block rotates, and the other linkage blocks are forced to move synchronously, so that one end of the resulting connecting rod B rotates and moves relative to the rotating block, so that the other end of the connecting rod B exerts a pulling force or a pushing force on the movable block through the corresponding rotating block, so that the movable block moves along the movable groove through the ball, driving the damping mechanism to rotate with the rotating ball center of the second ball connecting block B as the center of the circle, the damping mechanism changes synchronously at an angle, and the adjustment is convenient.

[0029] 4. The present invention sets the power mechanism as a screw-type moving structure, so that the position is automatically fixed after movement, thereby fixing the position of the connecting rod A, providing a force to the movable block to fix the movable block, so that the damping mechanism is automatically fixed after the angle changes, and setting a planetary transmission of the power mechanism to reduce the rotational resistance of the motor, and reduce the indirect rotational resistance of the high-weight electronic information equipment to the motor, so that a relatively small-power motor can be used to reduce costs, and the fixed block rotates slower than the motor, which is convenient for precise adjustment of the angle of the damping mechanism when encountering different road conditions.

[0058] The spring components A3, which are equal in number to the first ball connection blocks B14, are arranged in the gap between the first ball connection block A12 and the second ball connection block A23, and the two ends of the spring components A3 are respectively connected to the ball heads of the first ball connection block A12 and the second ball connection block A23; specifically, the spring components A3 include springs A31, both ends of the springs A31 are fixed with circular plates A32, the two circular plates A32 are relatively far from one end and are fixed with mounting rods A33, the two mounting rods A33 are relatively far from one end and are fixed with ball blocks A34, and the two ball blocks A34 are respectively connected to the ball heads of the first ball connection block A12 and the second ball connection block A23. Through the above arrangement, the elasticity of the multiple springs A31 is damaged differently after long-term use, and the elastic force of the multiple springs A31 can also be adjusted to ensure the balance of the elastic force, so that after the distance between the second ball connection block A23 and the first ball connection block B14 is adjusted, the length of the indirect spring A31 can be adjusted, and it is suitable for electronic information equipment of different weights.

[0059] The damping mechanism 4 is arranged in the gap between the first ball connecting block B14 and the second ball connecting block B24, and the two ends of the damping mechanism 4 are respectively connected to the ball heads of the first ball connecting block B14 and the second ball connecting block B24; the damping mechanism 4 includes a damper 41, a circular plate B42 is fixedly provided at the input end of the damper 41, an external thread 43 is provided on the surface of the damper 41 away from the circular plate B42, an adjustment block 44 is threadedly connected to the external thread 43, a spring B45 is fixedly provided at one end of the circular plate B42 close to the adjustment block 44, a collar 46 is fixedly provided at one end of the spring B45 close to the adjustment block 44, the collar 46 is rotatably connected to the adjustment block 44, and a cavity is formed by the gap between the collar 46 and the damper 41, mounting connecting rods B47 are fixedly provided at both ends of the damper 41, and ball blocks B48 are fixedly provided at the relatively distant ends of the two mounting connecting rods B47, and the two ball blocks B48 are respectively connected to the ball heads of the first ball connecting block B14 and the second ball connecting block B24.

[0063] The power mechanism 6 is arranged on one side of the base 1, and the output end of the power mechanism 6 is connected to the input end of the linkage mechanism 5. The power mechanism 6 includes a motor 61 and a fixing ring 62; the motor 61 is arranged on one side of the base 1 relative to the linkage block 57, and the motor 61 is fixedly connected to the base 1 through a mounting seat; the fixing ring 62 is fixedly arranged on one side of the base 1 relative to the output shaft position of the motor 61, and the inner edge surface of the fixing ring 62 is rotatably connected with a rotating tube 63 through a bearing, and the rotating tube 63 passes through the wall of the base 1 and extends into the mounting cavity 11, and the rotating tube 63 is rotatably connected to the wall of the base 1 through a bearing, and the rotating tube A fixing block 64 is fixedly provided at one end of 63 away from the motor 61, a screw rod 60 is threadedly connected to the fixing block 64, the screw rod 60 is fixedly connected to the linkage block 57, an inner gear ring 65 is fixedly provided at one end of the rotating tube 63 close to the motor 61, a mounting circular plate 66 is fixedly provided at one end of the fixing ring 62 close to the motor 61, a gear A67 is rotatably connected at the center of the mounting circular plate 66 via a rotating rod B, the rotating rod B is fixedly connected to the output shaft of the motor 61, the gear A67 is meshed with the inner gear ring 65 via a plurality of gears B68, and the gear B68 is rotatably connected to the mounting circular plate 66 via a rotating rod C. The present invention adopts the above arrangement to make the output shaft of the motor 61 rotate, so that the gear A67 drives the gear B68 and the inner gear ring 65 to rotate in turn, so that the fixed block 64 rotates. Since the screw rod 60 is fixedly connected with the linkage block 57, the linkage block 57 is fixed on the slider 56 that cannot rotate, and the rotating block 502 moves accordingly, the screw rod 60 cannot rotate, and the fixed block 64 rotates so that the screw rod 60 can link the block 57 and the slider 56 to slide along the slide rail 55. The present invention sets the power mechanism 6 as a screw rod type moving structure, so that the rear position of the moving The device is automatically fixed, so that the position of the connecting rod A58 is fixed, and a force is provided to the movable block 131, so that the movable block 131 is fixed, so that the damping mechanism 4 is automatically fixed after the angle changes, and a planetary transmission is set for the power mechanism 6 to reduce the rotation resistance of the motor 61, and reduce the indirect rotation resistance of the high-weight electronic information equipment to the motor 61, so that a relatively small-power motor can be used to reduce costs, and the fixed block 64 rotates slower than the motor 61, which is convenient for precise adjustment of the angle of the damping mechanism 4 when encountering different road conditions.

[0064] Working principle: Before transportation, the base 1 is fixed on the transport vehicle, and the electronic information equipment is placed on the placement table 2 and fixed by a clamp;

[0065] During transportation, the electronic information equipment vibrates during transportation, causing the spring assembly A3 and the damping mechanism 4 to compress or extend. The damping mechanism 4 has resistance in both expansion and contraction to consume the force generated by the vibration, thereby providing a seismic isolation effect.

[0066] In addition, the damping mechanism 4 and the spring assembly A3 are both connected to the placement table 2 by a ball head, so that the placement table 2 can move in a three-dimensional and all-round manner to buffer all-round vibrations;

[0067] When the transport vehicle is driving on a bumpy road, the electronic information equipment is subjected to a large vertical amplitude. Fig. 9 The damping mechanism 4 is shown in a tilted state. Fig.10 It can be seen that, for the same vertical amplitude length, the deformation length of the damping mechanism 4 in the horizontal state after the vertical amplitude is smaller than the deformation length of the damping mechanism 4 in the inclined state after the vertical amplitude, and the deformation length of the damping mechanism 4 is proportional to the force consumed by the damping mechanism 4, so when the damping mechanism 4 is in an inclined state, the vertical shockproof capability of the present invention is better;

[0068] When transport vehicles are driving on flat roads, the electronic information equipment is subject to large horizontal vibrations. Figure 2 The damping mechanism 4 is shown in a horizontal state. Fig.11 It can be seen that L7 is the transverse amplitude length, which is also the deformation length of the damping mechanism 4 in the horizontal state after the transverse amplitude, and the deformation length of the damping mechanism in the inclined state after the transverse amplitude is the difference between L4 and L8. According to the theorem that the difference between any two sides of a triangle is less than the third side, the deformation length of the damping mechanism in the inclined state after the transverse amplitude is less than the deformation length of the damping mechanism 4 in the horizontal state after the transverse amplitude. Therefore, the damping mechanism 4 in the horizontal state has better shockproof ability in the horizontal direction;

[0069] The angle of the damping mechanism 4 is adjusted by controlling the output shaft of the motor 61 to rotate through an external control mechanism, so that the gear A67 drives the gear B68 and the inner gear ring 65 to rotate in turn, so that the fixed block 64 rotates. Since the screw rod 60 is fixedly connected to the linkage block 57, the linkage block 57 is fixed on the slider 56 that cannot rotate, and the rotating block 502 moves accordingly, the screw rod 60 cannot rotate, and the fixed block 64 rotates, causing the screw rod 60 to drive the linkage block 57 and the slider 56 to slide along the slide rail 55, and the linkage block 57 drives the connecting rod A58 to move synchronously, so that The guide rod 54 drives the guide block 53 to move in the guide groove 52, causing the installation round block 51 to rotate, so that the other linkage blocks 57 are forced to move synchronously, causing one end of the resulting connecting rod B501 to rotate and move relative to the rotating block 502, so that the other end of the connecting rod B501 exerts a pulling force or a pushing force on the movable block 131 through the corresponding rotating block 502, so that the movable block 131 moves along the movable groove 115 through the ball 132, driving the damping mechanism 4 to rotate with the rotating ball center of the second ball connecting block B24 as the center, and the angle of the damping mechanism 4 changes.
