[0038] Referring to Figures 1 to 6 , in a first aspect, the present utility model provides a vibration isolation main board, including: a main board component 10, an elastic body 20, and a mounting board 30. The elastic body 20 is detachably connected to the main board component 10, and the elastic body 20 includes a first annular outer groove 21. The mounting board 30 is provided with a first through hole 31 and a first notch 32. The first notch 32 extends from the first through hole 31 to the edge of the mounting board 30; through the deformation of the elastic body 20, the first annular outer groove 21 enters the first through hole 31 through the first notch 32. When the elastic body 20 returns, the first annular outer groove 21 engages with the edge of the first through hole 31.

[0039] Specifically, the vibration isolation main board of this embodiment can be applied to devices such as lawn mowing equipment, snow removal equipment, and garden robots, or any device that generates vibrations during use.

[0040] The mounting plate 30 can be a mounting plate 30 made of any material. It is used to hold the main board assembly 10 and mainly serves to fix the main board assembly 10. The main board assembly 10 can be the main board itself or a potted main board module. The main board can also be referred to as a circuit board, a PCB board, etc. During installation, after the main board assembly 10 is installed on the mounting plate 30, the mounting plate is fixed to the bottom plate 50.

[0041] The elastomer 20 can be a rubber body with high elasticity or a silica gel body. One end of the elastomer 20 is detachably connected to the main board assembly 10. The elastomer 20 can be fixed to the main board assembly 10 by fastening screws or clamped to the main board assembly 10 by a clamping method. The shape of the elastomer 20 can be cylindrical or prismatic, or can be designed into any shape according to needs.

[0042] The elastomer 20 has a first annular outer groove 21. At the same time, the mounting plate 30 is provided with a first through hole 31 and a first notch 32. The first through hole 31 is adapted to the first annular outer groove 21. The first notch 32 extends from the first through hole 31 to the edge of the first mounting plate 30. That is to say, the first notch 32 is opened at the edge of the first mounting plate 30, and the opening of the first through hole 31 communicates with the first notch 32. The first through hole can be provided at a position close to the edge of the mounting plate, which can further facilitate the installation of the elastomer.

[0043] The edge of the first through hole 31 is not a complete circle but an arc. In this embodiment, the edge shape of the first through hole 31 is a major arc. That is to say, the first through hole 31 is a major arc-shaped hole. The width between the two ends of the arc is the width of the first notch 32. In this way, the width of the first notch 32 is smaller than the diameter of the major arc-shaped hole, which can ensure that the elastomer 20 is not easily detached from the mounting plate 30.

[0044] In some embodiments, the first through holes 31 and the first notches 32 are in one-to-one correspondence. In other embodiments, one first through hole 31 can correspond to multiple first notches 32, or one first notch 32 can correspond to multiple first through holes 31. The number and positions of the first through holes 31 and the first notches 32 can be determined according to the actual structure and installation situation.

[0045] In the above embodiments, when the elastomer is installed on the mounting plate, the elastomer 20 is manually squeezed to deform, so that the first annular outer groove 21 enters the first through hole 31 through the first notch 32. When the elastomer 20 resumes its shape, the first annular outer groove 21 catches the edge of the first through hole 31, thereby completing the installation of the elastomer 20 and the mounting plate 30.

[0046] In some embodiments, the ratio of the width of the first notch 32 to the diameter of the first through hole 31 is 0.53 - 0.72.

[0047] Specifically, the ratio of the width of the first notch 32 to the diameter of the first through hole 31 can limit the size of the first notch 32 relative to the size of the first through hole 31, thereby ensuring that the first notch 32 is neither too large nor too small. If the first notch 32 is too large, it will affect the stability of the elastomer 20 on the mounting plate 30. If the first notch 32 is too small, it will affect the ease of squeezing the elastomer 20 into the first through hole 31 from the first notch 32. In a specific embodiment, the ratio of the width of the first notch 32 to the diameter of the first through hole 31 can be 0.625. For example, the width of the first notch 32 is 3.5 mm, and the diameter of the first through hole 31 is 5.6 mm.

[0048] Please refer to Figure 3 , in some embodiments, the mounting plate 30 is provided with at least a pair of first through holes 31 and at least a pair of first notches 32; each first through hole 31 corresponds to a first notch 32 one by one, and the opening directions of each pair of first notches 32 are opposite.

[0049] Specifically, the first through holes 31 and the first notches 32 on the mounting plate 30 correspond to each other one by one, and the first through holes 31 are arranged in pairs. Correspondingly, the first notches 32 are also arranged in pairs, and the opening directions of the two first notches 32 arranged in pairs are opposite. Figure 3 In, the mounting plate 30 is provided with paired first through holes 31a and first through holes 31b, and correspondingly provided with first notches 32a and first notches 32b. The shape of the mounting plate 30 is rectangular. In the width direction of the mounting plate 30, the opening direction of the first notch 32a faces the width direction of the mounting plate, and the opening direction of the first notch 32b faces away from the width direction. In this way, the opening directions of the first notch 32a and the second notch b are arranged in opposite directions. In this embodiment, since the opening directions of the paired notches are opposite, when the main board assembly shakes, a reciprocating pulling force will be generated on the elastomer. The reciprocating pulling force can repeatedly pull the elastomer in the opening direction and the opposite direction of the opening direction, so that the displacement will not accumulate in the opening direction all the time, further ensuring that the elastomer 20 is not easily detached from the mounting plate 30.

[0050] In some embodiments, the diameter of the first annular outer groove 21 is greater than the diameter of the first through hole 31.

[0051] Specifically, the diameter of the first annular outer groove 21 of the elastomer 20 is slightly larger than the diameter of the first through hole 31, so that the elastomer 20 can be firmly attached to the first through hole 31. In this way, when vibrating, the elastomer 20 is not easily detached from the mounting plate 30.

[0052] In some embodiments, along the direction perpendicular to the side wall of the first annular outer groove 21, the elastomer 20 is provided with a third through hole 22.

[0053] Specifically, since the deformation amount of the elastomer 20 is limited, it may be difficult to install the elastomer 20 into the first through hole 31 through the first notch 32 due to insufficient deformation amount during installation. Along the direction perpendicular to the first outer annular groove, the elastomer 20 is provided with a third through hole 22. In this way, when the elastomer is squeezed, the outer dimension of the elastomer 20 changes more greatly, further increasing the convenience of installing the elastomer 20. And if necessary, the elastomer can also be fixed by screws through the third through hole 22.

[0054] In some embodiments, the main board assembly 10 includes: a potting board 11 and a main board 12 mounted on the potting board 11; the potting board 11 is provided with a second through hole, and the elastomer 20 includes a second annular outer groove 23, and the second annular outer groove 23 is engaged with the edge of the second through hole.

[0055] Specifically, the potting board 11 is used to carry the main board 12 and the main board 12 is potted and sealed to form the main board assembly 10, which can prevent the components on the main board 12 from failing due to the influence of the external environment. The potting board 11 is provided with a second through hole, and the elastomer 20 includes a second annular outer groove 23 adapted to the second through hole, and the second annular outer groove 23 is also fixed at the second through hole by a clamping method.

[0056] In some embodiments, the diameter of the second annular outer groove 23 is larger than the diameter of the second through hole. In this way, the bottom of the second annular outer groove 23 can closely abut against the edge of the second through hole, ensuring the connection stability of the elastic member on the potting board 11.

[0057] In some embodiments, the potting board 11 is further provided with a second notch, and the second notch extends from the second through hole to the edge of the potting board 11; through the extrusion deformation of the elastomer 20, the second annular outer groove 23 enters the second through hole through the second notch, and when the elastomer 20 returns, the second annular outer groove 23 is engaged with the second through hole.

[0058] In this embodiment, a notch is also provided on the potting board 11, that is, the second notch, and the second notch extends from the second through hole to the edge of the potting board 11. That is to say, a second notch can be opened at the edge of the potting board 11, and the opening of the second through hole communicates with the second notch. During installation, manually squeeze the elastomer 20 to generate deformation, so that the second annular outer groove 23 enters the second through hole through the second notch. When the elastomer 20 returns to its original shape, the second annular outer groove 23 is clamped to the edge of the second through hole, thereby completing the installation of the elastomer 20 and the potting board 11.

[0059] Please refer to Figure 5 , in some embodiments, the potting board 11 includes a main board support portion 111 and a mounting portion 112 located on the side of the main board support portion 111, and the second through hole is located in the mounting portion 112.

[0060] Specifically, the main board support part 111 is used to install the main board 12. Since the potting board 11 needs to pot and seal the main board 12 to form the main board assembly 10, in order to facilitate the overall disassembly and assembly of the main board assembly 10, an installation part 112 is provided on the side of the main board support part 111. After the main board is installed on the main board support part 111, potting is carried out on the main board support part to seal the main board. The installation part 112 is used to connect with the installation board 30, so as to fix the potting board 11 on the installation board 30. In this way, when disassembling and assembling the main board or the main board assembly, there is no need to consider the potting glue problem, and the main board can be directly removed from the installation board.

[0061] In some embodiments, it further includes a limiting member 40 respectively connected to the main board assembly 10 and the installation board 30. The limiting member 40 is used to fix the relative positions of the installation board 30 and the main board assembly 10.

[0062] Specifically, the limiting member 40 is arranged on the sides of the main board assembly 10 and the installation board 30, and is used to limit the distance between the main board assembly 10 and the installation board 30, reduce the shaking amplitude of the main board assembly 10, improve the stability of the main board assembly 10 on the installation board 30, and prevent the main board assembly 10 from shaking too much during the vibration of the machine and causing damage to the components.

[0063] In a specific embodiment, the limiting member 40 may include a limiting stud 41, a screw 42 and a washer 43. An installation hole is opened on the potting board 11, and another installation hole is opened on the installation board 30. The limiting stud passes through the potting board 11 and the installation board 30, and the screw 42 is locked at one end of the limiting stud 43 close to the potting board 11. A washer 43 is arranged between the screw 42 and the limiting stud 43, so as to limit the potting board 11 and the installation board 30.

[0064] In a second aspect, the present utility model also proposes a robot, including a bottom plate 50 and the vibration isolation main board described in any one of the above embodiments. The vibration isolation main board is detachably installed on the bottom plate 50.

[0065] Specifically, the robot can be a courtyard robot used outdoors, such as a snow sweeping robot, a lawn mowing robot, a pruning robot, etc., or a household robot, such as a floor sweeping robot, a floor washing robot, etc. The robot includes a bottom plate 50, and the vibration isolation main board is fixed on the bottom plate 50. The vibration isolation main board can be installed on the bottom plate 50 by means of locking screws or snap connections.

[0066] In summary, the present utility model provides a vibration isolation main board and a robot. The vibration isolation main board includes a main board assembly; an elastomer detachably connected to the main board, the elastomer including a first annular outer groove; and a mounting plate provided with a first through hole and a first notch, the first notch extending from the first through hole to the edge of the mounting plate. Through the deformation of the elastomer, the first groove enters the first through hole through the first notch, and when the elastomer recovers, the first groove is clamped to the edge of the first through hole. Since the first notch extends from the first through hole to the edge of the mounting plate, an opening is formed at the edge of the mounting plate, enabling the elastomer to be squeezed into the through hole from the side, facilitating the installation of the elastomer on the mounting plate.

[0067] The above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model, and should all be included within the protection scope of the present utility model.
