Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explanation of the present invention and is not to be construed as limiting the present invention, and modifications to the present embodiment, which may not creatively contribute to the present invention as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present invention.
In embodiment 1, as shown in fig. 1 and 2, in the present embodiment, a double-layer case is separately designed, and an inner case 2 and an outer case 1 located outside the inner case 2 are respectively provided, and all electronic components are provided in the inner case 2. In the use process of the power equipment, vibration in the front-back direction, the up-down direction, the left-right direction and the up-down direction can be generated, and the inner box 2 also generates vibration in the three directions, so that the vibration can be absorbed by the damping structure in the technical scheme.
First, in the vertical direction, the inner case 2 is held by its own weight in addition to the vibration in the vertical direction. This case has adopted the scheme of secondary shock attenuation in the vertical direction. Specifically, as shown in fig. 2, a rubber layer 31 is disposed below the inner case 2, a support plate 33 is disposed below the rubber layer 31, and the support plate 33 may be made of a metal material. The deformation of the rubber layer 31 decomposes and absorbs the vibration in the vertical direction for the first time, and realizes the primary vibration reduction in the vertical direction. A damper spring 33 and a damper 34 are provided in this order from top to bottom below the support plate 33. The upper end of the damping spring 33 is connected with the lower part of the supporting plate 33, and the lower end is connected with the damper 34. The lower end of the damper 34 is connected with the surface of the outer box 1. The second-stage decomposition absorption of the shock in the vertical direction is achieved by the deformation of the damper spring 33 and the displacement of the damper 34. The damper 34 and the damper spring 33 may be manufactured by a conventional method, and are not particularly limited in this case.
Next, in the lateral direction, there are vibrations in both the front-rear direction and the left-right direction. In the horizontal front-rear direction, there is a front-rear elastic member 4 for shock absorption and buffering. As shown in fig. 2 and 4, the left-right direction on the drawing sheet of fig. 2 is the front-rear direction described herein. Specifically, metal rubber columns 41 are provided on the outer surface of the side wall of the inner case 2 and the inner side wall of the outer case 1. The metal rubber is a new material, is a homogeneous elastic porous material, and is formed by orderly discharging a certain mass of stretched and spiral metal wires into a stamping or rolling die by a certain technological method and then using a cold stamping method. Its raw material is metal wire, which has the inherent characteristics of the selected metal and has rubber-like elasticity. A plurality of elastic pieces 42 are arranged around the metal rubber column 41 in a surrounding manner, the number of the elastic pieces 42 can be defined according to practical situations, the elastic pieces 42 are arranged in an arc shape, and two sides of the elastic pieces are connected with two ends of the metal rubber column 41. The first decomposition and absorption of the partial vibration in the front-rear direction are performed by the expansion deformation of the elastic sheet 42, the first vibration reduction in the front-rear direction of the apparatus is realized, and the second decomposition and absorption of the partial vibration in the front-rear direction is performed by the deformation of the metal rubber column 41, so that the second vibration reduction in the front-rear direction of the apparatus is realized. In addition, in this embodiment, 6 elastic pieces 42 are disposed on the outer ring of each metal rubber column 41, and when the displacement range caused by vibration reaches a predetermined level, the elastic pieces 42 are mutually restricted so that the displacement deformation in the direction cannot be increased continuously, thereby ensuring that the elastic pieces 42 can work within the normal working range, and ensuring the service life of the vibration reduction box of the electric equipment.
Again, in the other direction in the lateral direction, i.e., the left-right direction, left-right elastic members 5 are provided. In practical operation, the vibration from the left and right directions tends to be the greatest, so in this case, the left and right elastic members 5 adopt a three-layer shock absorbing design. Specifically, as shown in fig. 2 and 3, the left-right direction of the drawing in fig. 3 is the left-right direction described herein. And the front-rear direction mentioned above is the up-down direction of the drawing sheet in fig. 3. A mount 54 is provided on the outer surface of the outer case 1, and a rotation shaft 55 is provided on the mount 54, and the rotation shaft 55 is connected to the center position of the hard lever 51 by a member such as a bearing so that the hard lever 51 can rotate in the horizontal direction about the rotation shaft 55. Two sets of link cushioning assemblies 52 are also included, each connected to either end of the rigid rod 51 by means such as a knuckle bearing. The non-jacketed link buffer assembly 52 comprises two-section links, namely link one 521 and link two 522, which rely on a link spring 524 therebetween. A shock absorbing rubber 523 is also mounted in the cavity of spring 524. One end of the second link 522 is connected to the hard rod 51, the other end is connected to the first link 521 through a link spring 524, and the other end of the first link 521 is connected to the fixing device 53 through a member such as a knuckle bearing. The fixing means 53 are intended to be connected to the outer side wall of the inner tank 2. As shown in fig. 1 and 3, the fixing device 53 includes a fixing block 531 fixedly connected to the inward direction 2. The fixing block 531 and the boss 532 are provided with round holes for the pin shaft to pass through, and the pin shaft is connected with the knuckle bearing to realize the connection of the fixing device 53 and the first connecting rod 521. The purpose of the boss 532 is to ensure that the fixed mass 531 and the knuckle bearing do not interfere during operation.
The first decomposition and absorption are carried out on the split vibration in the left-right direction through the compression or tensile deformation of the connecting rod springs 524, the first vibration reduction in the left-right direction of the equipment is realized, the two connecting rod springs 524 are equally loaded through the rotation of the arranged hard rod 51, and the split vibration is transferred to the inner box 2 to offset the vibration, so that the second decomposition and absorption are carried out on the split vibration in the direction, the second vibration reduction in the left-right direction of the equipment is realized, and the third decomposition and absorption are carried out on the split vibration in the left-right direction through the deformation of the metal rubber through the setting of the damping rubber 523.
