Taking the second clamping protrusion 327 provided on the first plate body 32a as an example, the lateral end face of the second clamping protrusion 327 and the end face of the first plate body 32a facing the first bracket 31 are arranged at intervals, and the formed interval space can exactly accommodate the abutting position 343 on the connecting plate 34; the second clamping protrusion 327 is provided on the fifth plate body, and the second clamping protrusion 327 and the fifth plate body 32e also form another interval space for accommodating another abutting position 343 on the connecting plate 34. The second clamping protrusion 327 on the first plate body 32a and the second clamping protrusion 327 on the fifth plate body 32e, as the clamping protrusions on the head and tail sides, and the bracket body of the second bracket 32 jointly contact the abutting position 343 of the connecting plate 34.

[0083] In some embodiments, all the protrusion structures are arranged at intervals in sequence along the direction of the interval arrangement of the plate body structures to form a plurality of spaced clamping and limiting positions arranged in a straight line, strengthening the tightness of the connection between the first bracket 31 and the second bracket 32 and the connecting plate 34 respectively, so that the skeleton assembly 3 can effectively and evenly distribute the acting force transmitted by the vibration source.

[0084] In some embodiments, in the direction of the interval arrangement of the plate body structures, there are at least four protrusion structures. The arrangement directions of the two protrusion structures at the head and tail are offset from the direction of the interval arrangement of the plate body structures, and the remaining protrusion structures are arranged at intervals in sequence along the direction of the interval arrangement of the plate body structures. This kind of setting is beneficial to weakening and offsetting the vibration acting forces transmitted by the plurality of transmission rods 33 with different misaligned force transmission nodes on the connecting plate 34 and the first bracket 31 and the second bracket 32. Taking the plurality of first clamping protrusions 317 on the first bracket 31 as an example, see Figure 5, there are 5 first clamping protrusions 317. The middle three first clamping protrusions 317 are arranged in the same linear direction. The leftmost first clamping protrusion 317 and the rightmost first clamping protrusion 317 are arranged in the same linear direction, and the two linear directions are arranged in a staggered manner. The linear arrangement direction of the leftmost first clamping protrusion 317 and the rightmost first clamping protrusion 317 is farther away from the second bracket 32 than the linear arrangement direction of the middle three first clamping protrusions 317. With this kind of setting, the asynchronous force transmission between the connecting plate 34 and the upper side of the first bracket 31 and the second bracket 32 and at the corner nodes can be established, which can weaken the vibration acting forces and avoid the instability of the overall skeleton assembly 3.

In a specific embodiment, the connecting plate 34 is provided with a connection hole 345 for clearance fitting the second connection end 334. When the force transmission rod 33 elastically deforms during the transmission of the vibration of the vibration source, the connection hole 345 allows the second connection end 334 to elastically displace therein to consume the vibration energy, reduce the vibration effect, and improve the shock absorption ability of the skeleton assembly 3 to the vibration source.

[0086] As a preferred embodiment, referring to Figure 7 , the force transmission rod 33 further includes a columnar structure 335.

The cross-sectional area of the columnar structure 335 close to the inner bottom wall end face of the housing 1 is smaller than the cross-sectional area of the second connection end 334 close to the inner bottom wall end face of the housing 1. With this kind of setting, on the one hand, it is beneficial to the elastic deformation range of the force transmission rod 33 itself, which can displace and tilt with the vibration acting force, reducing the contact constraint of the housing 1 on the force transmission rod 33; on the other hand, it is beneficial to reduce the transmission path of the vibration from the force transmission rod 33 to the housing 1, enabling the skeleton assembly 3 to maximize the consumption of the vibration energy of the vibration source.

The first bracket 31 and the second bracket 32 are combined and spliced through the plug - in structure and the housing 1, and the first bracket 31 and the second bracket 32 jointly connect and restrain the connecting plate 34 to form an overall skeleton assembly 3. In some embodiments, the plug - in part 315 is set as a male tenon, the mating part 325 is set as a female tenon, the male tenon is set as a square column, and the female tenon is set as a column structure 335 with a square groove that has an interference fit with the square column.

[0091] As a further implementation method, in order to enhance the limiting elasticity of the limiting groove to form a reliable radial limit for the motor module 5 and the flexible adapter assembly 4, a reinforcing structure can be provided on the first bracket 31 and the second bracket 32. Taking the first bracket 31 as an example, see Figure 5 A reinforcing portion 319 is provided on the first bracket 31, and the reinforcing portion 319 extends along the height direction of the first bracket 31 to enhance the structural strength of the side of the plate structure adjacent to the bracket body. Taking the first limiting groove 313 set on the fourth plate 31d as an example, the reinforcing portion 319 is set on the side of the bracket body away from the fourth plate 31d. This setting can make the elasticity of the fourth plate 31d close to the first limiting groove 313 better than the elasticity of the joint between the fourth plate 31d and the bracket body, so that the fourth plate 31d can be deformed better, the flexible contact between the first limiting groove 313 and the flexible adapter component 4 is improved, and the stability of the motor module 5 in the suspension structure is improved.

Such a setting, on the one hand, is beneficial to the elastic deformation range of the guide rod 63 itself, which can displace and tilt with the vibration acting force, reducing the contact constraint of the housing 1 on the guide rod 63; on the other hand, it is beneficial to reduce the transmission path of vibration from the guide rod 63 to the housing 1, enabling the skeleton assembly 3 to maximize the consumption of the vibration energy of the vibration source.

[0104] The utility model also provides an electrical silent control box, which includes a vibration source and a shock absorption and silent mechanism, and the vibration source is fixedly hung on the shock absorption and silent mechanism.

When vibration occurs during the working stage of the vibration source, the cover plate 2 contacts and acts on the sliding portion 721 to move upward. On the one hand, by the sliding portion 721 contacting and constraining the lateral end face of the cover plate 2, the displacement of the relative separation of the cover plate 2 and the housing 1 is limited. On the other hand, by the abutment of the limiting portion 722 and the lower end of the chute member 15, a fixed foundation can be established for the sliding portion 721 to prevent the sliding portion 721 from displacing under the upward action of the cover plate 2, and the stable connection ability between the housing 1 and the cover plate 2 is improved.
