[0025] See Figures 1-5 , this solution provides a shock-absorbing device for a mechatronic device, including a shock-absorbing platform 1, a support 2, and connecting legs 3. The shock-absorbing platform 1 is used to carry the mechatronic device; the support 2 is used to support the shock-absorbing platform 1; the connecting legs 3 are connected between the shock-absorbing platform 1 and the support 2; the connecting legs 3 include a horizontal buffer assembly and a vertical buffer assembly. The horizontal buffer assembly is arranged horizontally in the shock-absorbing platform 1 along the horizontal direction of the shock-absorbing platform 1 and is used to filter and buffer the shock-absorbing platform 1 in the horizontal direction; the vertical buffer assembly is arranged vertically under the shock-absorbing platform 1 in a magnetic levitation form and is used to filter and buffer the shock-absorbing platform 1 in the vertical direction.

[0026] The shock-absorbing platform 1 of this solution is configured with multiple shock-absorbing legs, and the shock-absorbing platform 1 can generate a lateral displacement with the shock-absorbing legs. The shock-absorbing legs buffer the impact in the vertical direction, the shock-absorbing platform 1 and the horizontal buffer assembly buffer the vibration in the horizontal direction, and the vertical buffer assembly buffers the vibration in the vertical direction, reducing the vibration generated during the operation of the device; the vertical buffer assembly is arranged vertically under the shock-absorbing platform 1 in a magnetic levitation form, which can avoid generating a large vibration when being impacted, avoid a strong impact between devices, and can effectively generate the vibration during the handling and installation process, ensuring the service life of the device.

[0027] The shock-absorbing platform 1 is used to place the mechatronic device, and anti-slip patterns are provided on the upper part of the shock-absorbing platform 1 to prevent the mechatronic device from generating displacement with the shock-absorbing platform 1.

[0028] When the shock-absorbing platform 1 is square, at least [number] shock-absorbing legs are provided, and the multiple shock-absorbing legs are evenly arranged on the lower side of the shock-absorbing platform 1. The bottom area of the support 2 should be larger than the diameter of the connecting legs 3. The support 2 can be directly placed on the ground or fixed to the ground through connecting pieces such as anchor bolts.

[0029] In this embodiment, the vertical buffer assembly includes a first buffer rod 14, a first magnetic member, a second magnetic member, and a connecting housing. The fixed end of the first buffer rod 14 abuts against the bottom of the shock-absorbing platform 1. The movable end of the first buffer rod 14 is connected to the first magnetic member. One end of the second magnetic member is arranged opposite to the first magnetic member, and the other end of the second magnetic member; a connecting support 2. The first magnetic member and the second magnetic member repel each other. A first buffer cavity 4 is provided in the connecting housing. The fixed end of the first buffer rod 14 is connected to the connecting housing, and the movable end of the first buffer rod 14 extends into the first buffer cavity 4. The first magnetic member and the second magnetic member are both located in the first buffer cavity 4, and an adjustment cavity 7 is formed by surrounding the first magnetic member, the second magnetic member, and the first buffer cavity 4.

[0030] Wherein, the first magnetic member is an adjustment piston 5, and the second magnetic member is a sealing plug 6. When the shock-absorbing platform 1 is pressed, the buffer medium 8 is compressed after being pressed, and by increasing the magnetism of the adjustment piston 5, the buffer distance between the adjustment piston 5 and the sealing plug 6 is increased.

[0031] As Figure 5 shown, the adjustment piston 5 is an electromagnet, the sealing plug 6 is a permanent magnet, and a plurality of detection contacts are arranged in the height direction of the first buffer cavity 4. When the adjustment piston 5 contacts the detection contacts, a detection circuit is formed between the adjustment piston 5 and the detection contacts. The adjustment cavity 7 is filled with a buffer medium 8, and the buffer medium 8 includes a buffer liquid and compressed air. The buffer liquid is distributed in the lower layer of the compressed air. The detection contacts are used to detect the position of the adjustment piston 5. When the adjustment piston 5 reaches the top of the first buffer cavity 4, the magnetism of the adjustment piston 5 is controlled to increase, and the repulsive force on the sealing plug 6 is increased.

[0032] In this embodiment, the horizontal buffer assembly includes at least two groups of first elastic members 10. A first accommodation cavity 9 is provided at the bottom of the shock-absorbing platform 1. One end of the vertical buffer assembly is inserted into the first accommodation cavity 9. A second buffer cavity 4 extends horizontally from the side wall of the first accommodation cavity 9. One end of the first elastic member 10 abuts against the side wall of the second buffer cavity 4, and the other end of the first elastic member 10 abuts against the side wall of the vertical buffer assembly. When the shock-absorbing platform 1 generates lateral shaking, the upper part of the connecting leg 3 can move inside the first accommodation cavity 9, and the shaking of the connecting leg 3 is buffered by the first elastic member 10. A damping sleeve can be arranged outside the first elastic member 10 to improve the buffer effect.

[0033] In this embodiment, the shock-absorbing device of the electromechanical equipment further includes an auxiliary buffer assembly. One end of the auxiliary buffer assembly is connected to the bottom of the shock-absorbing platform 1, and the other end of the auxiliary buffer assembly is obliquely connected to the vertical buffer assembly.

[0034] In this embodiment, the auxiliary buffer assembly includes a second buffer rod 15, an auxiliary buffer block 12, and a second elastic member 13. The fixed end of the second buffer rod 15 is connected to the vertical buffer assembly, and the other end of the second buffer rod 15 is connected to the auxiliary buffer block 12. A second receiving cavity 11 is provided at the bottom of the shock-absorbing platform 1. The auxiliary buffer block 12 is slidably disposed within the second receiving cavity 11. A third buffer cavity 4 extends horizontally from the side wall of the second receiving cavity 11. One end of the second elastic member 13 abuts against the side wall of the third buffer cavity 4, and the other end of the second elastic member 13 abuts against the auxiliary buffer block 12.

[0035] In this embodiment, the axial direction of the first elastic member 10 is parallel to the axial direction of the second elastic member 13, and the elastic coefficient of the first elastic member 10 is greater than the elastic coefficient of the second elastic member 13.

[0036] The auxiliary buffer block 12 is buffered by the second elastic member 13. The axis of the first elastic member 10 is horizontally parallel to the axis of the second elastic member 13. The top of the auxiliary buffer block 12 is fitted with the top of the second first buffer cavity 4, and the top of the connecting leg 3 is fitted with the top of the first first buffer cavity 4.

[0037] The shock-absorbing device includes a placement mode and a shock-absorbing mode. In the placement mode, when the mechanical equipment is placed on the shock-absorbing platform 1, the first buffer rod 14 is compressed and shortened, the adjustment cavity 7 is compressed and shortened, and the buffer medium 8 is further compressed, increasing the magnetism of the electromagnet, forming a magnetic levitation structure between the adjustment piston 5 and the sealing plug 6, and increasing the distance between the adjustment piston 5 and the sealing plug 6; In the shock-absorbing mode, the first elastic member 10 and the second elastic member 13 are used to buffer vibrations in the horizontal direction.

[0038] When the shock-absorbing platform 1 shakes, horizontal vibration filtering is performed through the second elastic member 13, the second buffer rod 15, and the first elastic member 10, reducing the shaking amplitude of the equipment.

[0039] Usage method: When the device is specifically used, the electromechanical equipment is placed on the upper part of the shock-absorbing platform 1 and fixed; During the placement of the electromechanical equipment, a downward impact force will be generated on the shock-absorbing device. After being pressed, the support 2 quickly rushes into the connecting leg 3, and the impact is buffered through the magnetic levitation structure and the buffer medium 8; When the impact force is too large, the first buffer rod 14 is compressed and shortened, the adjustment piston 5 moves upward along the adjustment cavity 7, and a detection circuit is formed between the adjustment piston 5 and the detection contact; When the adjusting piston 5 approaches the top of the first buffer chamber 4, the controller increases the magnetism of the adjusting piston 5, and the sealing plug 6 is pushed downward through the magnetic levitation structure, so that the adjusting piston 5 and the sealing plug 6 are maintained at a relatively safe height to avoid hard impacts on the internal structure of the first buffer chamber 4.

[0040] When the electromechanical equipment impacts downward, the adjusting chamber 7 is compressed, and the compressed air inside the adjusting chamber 7 is further compressed. The adjusting piston 5 and the sealing plug 6 approach each other, but due to the arrangement of the buffer medium 8, the sealing plug 6 and the adjusting piston 5 will not collide. This structure can efficiently buffer vertical vibrations and impacts.

[0041] When the shock-absorbing platform 1 shakes, vibration filtering and buffering are carried out through the first elastic member 10, the second elastic member 13 and the second buffer rod 15. The first buffer rod 14 and the second buffer rod 15 can be spring rods or hydraulic rods, which can shorten when pressed and reset when the pressure is released to maintain the support for the shock-absorbing platform 1.

[0042] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
