[0059] In this embodiment, see Figure 14 and Figure 15 , a slide member 15 is provided on the outer wall of the shell 1; the cover plate 2 is connected to the shell 1 to close the installation cavity; the connecting assembly 7 includes at least two limit plates 72, any limit plate 72 includes a sliding portion 721 and a limit portion 722, the sliding portion 721 and the slide member 15 are correspondingly arranged, the sliding portion 721 can be slidably connected to the slide member 15, the sliding portion 721 extends in a direction away from the limit portion 722, the sliding portion 721 is suitable for abutting the shell 1 and the cover plate 2 to constrain the shell 1 and the cover plate 2, a mounting node is provided on the extending portion of the sliding portion 721 away from the limit portion 722, the mounting node and the cover plate 2 are avoided, the mounting node is suitable for being connected to an external bed frame, and the limit portion 722 is abutted and connected to the side of the slide member 15 away from the cover plate 2.

[0060] In a specific embodiment, the connection assembly 7 is provided with three or more limit plates 72 to improve the flexible energy absorption capacity of the limit plates 72 so as to fully absorb the vibration energy transmitted from the vibration source to the external bed frame through the shell 1. Preferably, there are four limit plates 72, see Figure 14 , slide members 15 for installing limit plates 72 are provided at the four corners on the outside of the two opposite sides of the shell 1. The limit plates 72 are set as flexible damping plates. The four limit plates 72 are respectively nested and hung in the slide members 15 at the four corners on the outside of the two opposite sides of the shell 1, so as to achieve the purpose of flexible suspension of the shell 1 and realize vibration isolation, shock absorption and noise reduction.

[0061] As a further embodiment, see Figure 14The connection assembly 7 further includes a sealing ring 73, which is elastically pressed between the facing connection end surfaces of the housing 1 and the cover plate 2. In a specific embodiment, after the housing 1 and the cover plate 2 are assembled with the connection assembly 7, the sliding portion 721 abuts against the housing 1 and the cover plate 2 respectively, and the limiting portion 722 abuts against the lower end of the slide member 15. The housing 1 and the cover plate 2 are locked and constrained by the locking member 71. The sealing ring 73 elastically compresses the housing 1 and the cover plate 2. The cover plate 2 has an elastic tendency to move upward under the action of the sealing ring 73. When the vibration source vibrates during the working stage, the cover plate 2 contacts the sliding portion 721 upward. On the one hand, the sliding portion 721 contacts and constrains the lateral end surface of the cover plate 2, limiting the relative separation of the cover plate 2 and the housing 1. On the other hand, the limiting portion 722 abuts against the lower end of the slide member 15, establishing a fixed foundation for the sliding portion 721, preventing the sliding portion 721 from moving under the upward action of the cover plate 2, thereby improving the stable connection between the housing 1 and the cover plate 2.

[0062] In some embodiments, the shell 1 is configured as a hollow shell with an open upper end and surrounding edges. A circle of grooves suitable for accommodating a sealing ring 73 is provided on the upper end surface.

The connection and assembly of the limiting plate 72 and the sliding groove member 15 are quick, which is convenient for users to quickly assemble and disassemble.

[0065] As a preferred embodiment, the connecting assembly 7 includes two or more locking members 71, which are used to lock and connect the cover plate 2 and the shell 1; a connecting column 13 is provided on the inner bottom wall of the shell 1 corresponding to the locking member 71, and the locking end of the locking member 71 passes through the cover plate 2 to dock and lock with the connecting column 13, and the installation end of the locking member 71 is fixedly connected to the cover plate 2.

[0066] In some embodiments, see Figure 14 , there are multiple locking members 71, and multiple connecting columns 13 are provided in the shell 1. The connecting columns 13 are arranged on the bottom wall of the shell 1. In a specific embodiment, four locking members 71 and four connecting columns 13 are respectively provided. The four connecting columns 13 are respectively arranged at the four corners of the mounting cavity of the shell 1. The locking ends of the four locking members 71 pass through the cover plate 2 and are respectively connected to the four connecting columns 13 to assemble and fix the cover plate 2 to the shell 1 as a whole.

[0067] The electric silent control box provided in this embodiment is assembled with the limit plate 72 through the slide member 15 after the shell 1 and the cover plate 2 are combined and assembled. The upper limit portion 722 of the limit plate 72 abuts the slide member 15, and is connected to the external bed frame by utilizing the mounting node provided on the sliding portion 721, so that the shell 1 and the cover plate 2 can be hung on the external bed frame. The limit plate 72 serves to isolate the shell 1 and the external bed frame and absorb the energy transmitted from the vibration source to the external bed frame through the shell 1 to avoid causing vibration fluctuations of the external frame, thereby obtaining a good shock-absorbing and silent effect; and the shell 1 and the cover plate 2 are assembled in a limited manner on the sliding portion 721 by the limit plate 72, thereby strengthening the tight assembly of the two; the utility model can improve the stability of the control box, which is conducive to comfortable and silent use by users.

[0072] In this embodiment, see Figure 2The skeleton assembly 3 includes a first bracket 31, a second bracket 32, a force transmission rod 33, and a connecting plate 34. The first bracket 31, the second bracket 32, and the connecting plate 34 are assembled and spliced together.

The card slot is set as a semi-closed card slot with an open side, and the card slot can be set as a round-bottomed gourd-shaped card slot.

[0085] In a specific embodiment, the second bracket 32 is connected to two force transmission rods 33, and four connecting fins 321 are provided. The four connecting fins 321 are arranged in a square matrix. The two connecting fins 321 on one side correspond to one force transmission rod 33, and the two connecting fins 321 on the other side correspond to the other force transmission rod 33.

[0086] In other embodiments, two, three, five or more force transmission rods 33 may be provided.

[0087] In some embodiments, any bracket is provided with multiple protrusions, and any protrusion engages with the connecting plate 34. The protrusions are provided at the upper ends of the first bracket 31 and the second bracket 32, and the connection between the protrusions and the connecting plate 34 can adopt a mortise and tenon structure. Specifically, the protrusions are provided as tenon studs, and the connecting plate 34 is provided with mortise grooves.

[0088] The first bracket 31 includes a bracket body and a plurality of plate structures. The bracket body is configured as an extended flat plate. The plurality of plate structures are arranged at intervals from each other. The plate structures are configured on the same side of the bracket body and extend toward the second bracket 32. Figure 5 A first clamping protrusion 317 is provided on the plate structure, and the first clamping protrusion 317 is formed on the end surface of the plate structure away from the shell 1.

[0089] Correspondingly, the second bracket 32 also includes a bracket body and a plurality of plate structures, see Figure 6 A second clamping protrusion 327 is provided on the plate structure, and the second clamping protrusion 327 is formed on the end surface of the plate structure away from the shell 1.

[0090] As a further embodiment, see Figure 8The connecting plate 34 is provided with a plurality of first snap-fit grooves 341 and a plurality of second snap-fit grooves 342 , and the snap-fit grooves are opened on the outer edge area of the connecting plate 34 ; the first snap-fit grooves 341 are arranged along the length direction of the connecting plate 34 , and the second snap-fit grooves 342 are arranged along the width direction of the connecting plate 34 .

[0091] As a preferred embodiment, the first bracket 31 and the second bracket 32 can be symmetrically configured with snap-fit protrusions on both sides of the connecting plate 34, so as to connect the plate 34 through the clamping action of the snap-fit protrusions and the snap-fit grooves, which is beneficial to improving the overall structural strength of the skeleton assembly 3 and evenly distributing the force transmitted by the vibration source.

[0092] As a preferred embodiment, see Figure 2 The splicing structure of the first bracket 31 and the second bracket 32 is provided with a sunken connection space, and the connection plate 34 is installed in the connection space; see Figure 8 The connecting plate 34 is configured as a polygonal plate structure. Abutment points 343 capable of contacting the splicing structure are provided at the nodes of the outer connecting edge of the connecting plate 34. At least one escape point 344 is provided on the outer connecting edge of the connecting plate 34. The escape point 344 is adapted to form an escape space with the splicing structure. The escape point 344 establishes deformation space in a local area of the connecting plate 34, thereby improving the connecting plate 34's ability to deform in response to vibration forces and enhancing the skeleton assembly 3's absorption of vibration energy. The abutment points 343 contact and limit the splicing structure to establish a constrained connection in the local area, preventing excessive deformation of the connecting plate 34 and ensuring the stability of the skeleton assembly 3.

[0093] In a specific embodiment, the connecting plate 34 is configured as a quadrilateral plate structure, with four abutment points 343 provided at the four corners of the connecting plate 34. A first engaging groove 341 and a second engaging groove 342 are provided along the length of the side edges of the connecting plate 34. Multiple clearance points 344 are provided along the length of the side edges of the connecting plate 34. The clearance points 344 are provided between two second engaging grooves 342 on the same side, avoiding the first engaging groove 341. With this configuration, the four inflection point connection nodes are relatively fixed through contact constraints between the abutment points 343 and the first and second brackets 31 and 32, ensuring that the connection nodes are relatively fixed, and the middle section of the lengthwise side edges of the connecting plate 34 undergoes stress deformation.

[0094] See also Figure 5 and Figure 6Taking the five plate structures respectively provided on the first bracket 31 and the second bracket 32 as an example, the five plate structures on the first bracket 31 are named: the first plate 31a, the second plate 31b, the third plate 31c, the fourth plate 31d and the fifth plate 31e; the upper ends of the five plates are respectively provided with first clamping protrusions 317 to clamp the connecting plate 34; the five plate structures on the second bracket 32 are respectively named: the first plate 32a, the second plate 32b, the third plate 32c, the fourth plate 32d and the fifth plate 32e; the upper ends of the five plates are respectively provided with second clamping protrusions 327 to clamp the connecting plate 34.

[0095] Along the length of the first bracket 31, the first plate 31a, second plate 31b, third plate 31c, fourth plate 31d, and fifth plate 31e are arranged in sequence. For example, the first engaging protrusion 317 on the first plate 31a is spaced apart from the end surface of the first plate 31a facing the second bracket 32. This creates a space that can precisely accommodate an abutment portion 343 on the connecting plate 34. The fifth plate 31e also has a first engaging protrusion 317. The first engaging protrusion 317 and the fifth plate 31e similarly form another space that accommodates another abutment portion 343 on the connecting plate 34. The first engaging protrusion 317 on the first plate 31a and the first engaging protrusion 317 on the fifth plate 31e serve as the leading and trailing engaging protrusions, and together with the bracket body of the first bracket 31, they contact the abutment portion 343 on the connecting plate 34.

[0096] Accordingly, along the length of the second bracket 32, the first, second, third, third, fourth, and fifth plates 32a, 32b, 32c, 32d, and 32e are arranged in sequence. For example, the second engaging protrusion 327 on the first plate 32a is spaced apart from the end surface of the first plate 32a facing the first bracket 31, creating a gap that can accommodate the abutment portion 343 on the connecting plate 34. The second engaging protrusion 327 on the fifth plate 32e also forms another gap that accommodates another abutment portion 343 on the connecting plate 34. The second engaging protrusion 327 on the first and second plates 32e, acting as the leading and trailing engaging protrusions, contact the abutment portion 343 on the connecting plate 34 with the bracket body of the second bracket 32.

[0097] In some embodiments, all the raised structures are arranged in sequence along the spacing direction of the plate structure to form a plurality of spaced-apart clamping limit positions arranged in a straight line, thereby strengthening the tightness between the first bracket 31 and the second bracket 32 and the connecting plate 34, respectively, so that the skeleton assembly 3 can effectively distribute the force transmitted by the vibration source.

[0098] In some embodiments, at least four protrusions are provided in the direction of the plate structure spacing. The line connecting the first and last protrusions is offset from the direction of the plate structure spacing, and the remaining protrusions are arranged in sequence along the direction of the plate structure spacing. This arrangement is conducive to weakening and offsetting the vibration force transmitted by the multiple force transmission rods 33 along the different offset force transmission nodes on the connecting plate 34 and the first bracket 31 and the second bracket 32. Taking the multiple first clamping protrusions 317 on the first bracket 31 as an example, see Figure 5 The first engaging protrusions 317 are provided with three first engaging protrusions 317 in the middle, arranged in the same linear direction. The leftmost first engaging protrusion 317 and the rightmost first engaging protrusion 317 are arranged in the same linear direction, and the two linear directions are staggered. The linear direction of the leftmost first engaging protrusion 317 and the rightmost first engaging protrusion 317 is arranged farther from the second bracket 32 than the linear direction of the three first engaging protrusions 317 in the middle. This arrangement can establish asynchronous force transmission between the connecting plate 34 and the upper side and corner nodes of the first bracket 31 and the second bracket 32, thereby weakening the vibration force and preventing instability of the entire skeleton assembly 3.

[0099] In some embodiments, see Figure 7 The force transmission rod 33 includes a first connecting end 333 and a second connecting end 334 that are arranged opposite each other. The first connecting end 333 is connected to the housing 1, and the second connecting end 334 is loosely assembled with the connecting plate 34. In a specific embodiment, the connecting plate 34 is provided with a connecting hole 345, through which the second connecting end 334 is loosely assembled. When the force transmission rod 33 elastically deforms while transmitting vibration from the vibration source, the connecting hole 345 allows the second connecting end 334 to elastically displace therein, thereby absorbing vibration energy, reducing the vibration effect, and improving the shock absorption capability of the skeleton assembly 3 against the vibration source.

[0100] As a preferred embodiment, see Figure 7 The force transmission rod 33 also includes a columnar structure 335, which is disposed on the end face of the second connecting end 334 away from the first connecting end 333. The cross-sectional area of the columnar structure 335 near the inner bottom wall of the housing 1 is smaller than the cross-sectional area of the end face of the second connecting end 334 near the inner bottom wall of the housing 1. This arrangement, on the one hand, facilitates the elastic deformation range of the force transmission rod 33 itself, allowing it to shift and tilt with the vibration force, thereby reducing the contact constraint of the housing 1 on the force transmission rod 33. On the other hand, it helps to reduce the transmission path of vibration from the force transmission rod 33 to the housing 1, allowing the skeleton assembly 3 to maximize the consumption of the vibration energy of the vibration source.

[0101] As a preferred embodiment, at least one load-reducing structure is provided on the area adjacent to the fins on any bracket. The load-reducing structure creates a local structural weakness area on the first bracket 31 and the second bracket 32, thereby improving the elasticity of the fins. Figure 5 and Figure 6 The first bracket 31 is provided with a load-reducing slot 312, which can be configured as an elongated slot and symmetrically arranged on either side of the connecting fin 311. The second bracket 32 is provided with a weakening slot 322, which can be configured as an elongated slot and symmetrically arranged on either side of the connecting fin 321. Of course, the load-reducing structure also serves to ventilate and dissipate heat for the motor module 5 within the skeleton assembly 3.

[0102] As a preferred embodiment, a plug-in structure is provided on the facing end surfaces of the first bracket 31 and the second bracket 32, and the first bracket 31 and the second bracket 32 are combined and spliced by the plug-in structure. Figure 5 and Figure 6 The plug-in structure includes a corresponding plug-in portion 315 and a plug-in portion 325. The plug-in portion 315 is disposed on the side of the first bracket 31 facing the second bracket 32, and the plug-in portion 325 is disposed on the side of the second bracket 32 facing the first bracket 31. The first bracket 31 and the second bracket 32 are assembled and spliced together through the plug-in structure and the housing 1. The first bracket 31 and the second bracket 32 are jointly connected to the restraining connecting plate 34 to form an integral skeleton assembly 3. In some embodiments, the plug-in portion 315 is configured as a male tenon, and the plug-in portion 325 is configured as a female tenon. The male tenon is configured as a square column, and the female tenon is configured as a column structure 335 having a square groove that is interference-fitted with the square column.

[0103] As a preferred embodiment, the first bracket 31 and the second bracket 32 are combined and spliced to form a limiting groove structure, which is suitable for constraining the radial vibration of the vibration source. The limiting groove structure is configured with at least two limiting grooves, and any two limiting grooves are spaced and arranged around the outside of the flexible adapter component 4; in a specific embodiment, see Figure 2 、 Figure 5 and Figure 6The limiting groove structure includes a first limiting groove 313 and a second limiting groove 314 provided on the first bracket 31, and a third limiting groove 323 and a fourth limiting groove 324 provided on the second bracket 32. The first limiting groove 313 and the third limiting groove 323 can be spliced together to form a closed groove body to limit and constrain the radial vibration displacement of the motor module 5. Similarly, the second limiting groove 314 and the fourth limiting groove 324 can be spliced together to form a closed groove body to limit and constrain the radial vibration displacement of the motor module 5. The first limiting groove 313 is provided on the fourth plate 31d, the second limiting groove 314 is provided on the second plate 31b, the third limiting groove 323 is provided on the second plate 32b, and the fourth limiting groove 324 is provided on the fourth plate 32d.

[0104] As a further embodiment, a stop structure is constructed on any bracket, the stop structure is suitable for restricting the axial vibration of the vibration source, and the stop structure is configured with at least one stop block, which is suitable for stopping the flexible adapter component 4. Figure 5 and Figure 6 A gap space suitable for the vibration capacity of the motor module 5 is provided between the stop block and the flexible adapter assembly 4, a first stop block 316 is provided on the end face of the first bracket 31 facing the second bracket 32, and a second stop block 326 is provided on the end face of the second bracket 32 facing the first bracket 31. After the first bracket 31 and the second bracket 32 are spliced and combined, the first stop block 316 and the second stop block 326 are in the working position to limit the axial vibration displacement of the motor module 5. A plurality of first stop blocks 316 and second stop blocks 326 can be respectively provided to increase the axial constraint area of the stop structure on the flexible adapter assembly 4 and the motor module 5, so that the motor module 5 is suspended and shock-absorbing in the desired area.

[0105] As a further embodiment, 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 The first bracket 31 is provided with a reinforcing portion 319, which 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 elastic ability of the fourth plate 31d close to the first limiting groove 313 better than the elastic ability of the joint between the fourth plate 31d and the bracket body, thereby enabling the fourth plate 31d to deform better, improving the flexible contact between the first limiting groove 313 and the flexible adapter component 4, and improving the stability of the motor module 5 in the suspension structure.

[0106] In some embodiments, see Figure 4The motor module 5 includes a first end 51, a second end 52, and a step portion 53. The first end 51 and the second end 52 are arranged opposite to each other, and the step portion 53 is arranged between them. The first end 51 has a larger diameter, and the second end 52 has a smaller diameter.

[0107] As a further embodiment, the plug-in structure is adapted to constrain the axial vibration of the vibration source. The corresponding plug-in portion 315 and the plug-in portion 325 are adapted to abut the limiting step 53, thereby limiting the axial vibration displacement of the motor module 5. The plug-in portion 315 and the plug-in portion 325 are each provided with a constraining surface facing the step 53. These constraining surfaces extend radially along the motor module 5. Initially, a gap exists between these constraining surfaces and the step 53 sufficient to accommodate the vibration tolerance of the motor module 5.

[0108] As a preferred embodiment, see Figures 2 to 4 The force transmission rods 33 are provided with four and four lifting ears are provided. The middle section of the force transmission rods 33 is fixedly connected to the lifting ears. The two ends of the force transmission rods 33 along the length direction are fixedly connected to the spliced structure of the first bracket 31 and the second bracket 32. The length direction of the force transmission rods 33 is arranged parallel to the extension direction of the first bracket 31. In a specific embodiment, the force transmission rods 33 are configured as an elastic long rod-shaped structure. The force transmission rods 33 are provided with four, two first lifting ears 413 are provided, and two second lifting ears 422 are provided. The four force transmission rods 33 are correspondingly connected to the two first lifting ears 413 and the two second lifting ears 422.

[0109] As a preferred embodiment, the flexible adapter assembly 4 includes a first adapter sleeve 41 and a second adapter sleeve 42 arranged at intervals. The first adapter sleeve 41 and the second adapter sleeve 42 are suitable for being respectively sleeved on the two ends of the motor module 5. Any adapter sleeve is provided with an outwardly protruding lifting ear, and the lifting ear and the force transmission rod 33 are fixedly connected.

[0110] In a specific embodiment, the first adapter sleeve 41 can be connected to the outside of the second end 52, and the second adapter sleeve 42 can be connected to the outside of the second end 52. The first adapter sleeve 41 is provided with a first lifting ear 413 protruding outwardly, and the second adapter sleeve 42 is provided with a second lifting ear 422 protruding outwardly.

[0111] In a preferred embodiment, see Figure 4The first adapter sleeve 41 can be connected to the outside of the second end portion 52 and the step portion 53, and the second adapter sleeve 42 can be connected to the outside of the first end portion 51. The first adapter sleeve 41 includes a No. 1 adapter sleeve 411 and a No. 2 adapter sleeve 412 connected to each other. The No. 1 adapter sleeve 411 is sleeved to cover the second end portion 52, and the No. 2 adapter sleeve 412 is sleeved to cover the step portion 53. The second adapter sleeve 42 includes a No. 3 adapter sleeve 421, and the No. 3 adapter sleeve 421 is sleeved to cover the first end portion 51, wherein the No. 3 adapter sleeve 421 and the No. 2 adapter sleeve 412 are arranged at intervals; any adapter sleeve is arranged as a rotating body structure; the No. 2 adapter sleeve 412 is sleeved to cover the step portion 53. This arrangement is conducive to improving the flexible energy absorption capacity of the flexible adapter assembly 4, and the first adapter sleeve 41 can further flexibly transmit the vibration force of the first end portion 51 to the force transmission rod 33; and is conducive to improving the coaxiality of the vibration effect of the motor module 5.

[0112] As a further embodiment, the first lifting lug 413 and the second lifting lug 422 are staggered along the axial direction of the vibration source. Specifically, the first lifting lug 413 and the second lifting lug 422 are staggered along the axial direction of the motor module 5. This arrangement is conducive to the flexible adapter assembly 4 converting the radial vibration and axial vibration in the motor module 5 into each other, so as to weaken the amplitude of the radial vibration or the axial vibration. After the force is converted and weakened, it is transmitted to the first bracket 31, the second bracket 32 and the connecting plate 34 through the force transmission rod 33, which can enhance the stability of the skeleton assembly 3 and improve the ability of the skeleton assembly 3 to absorb the vibration energy of the vibration source.

[0113] In this embodiment, the loading frame assembly 6 is used to assemble the solenoid valve group 8, which plays the role of suspension shock absorption. Unlike the skeleton assembly 3, the loading frame assembly 6 includes a mounting plate 65, which is used to install multiple solenoid valves in the solenoid valve group 8. One or more mounting plates 65 can be provided.

[0114] As an exemplary embodiment, see Figure 9 The loading frame assembly 6 includes a first bracket 61 and a second bracket 62 arranged on both sides of the solenoid valve group 8, a guide rod 63 arranged between the first bracket 61 and the second bracket 62, and a docking plate 64 arranged at the upper ends of the first bracket 61 and the second bracket 62.

[0115] See also Figures 10 to 13The first hanging bracket 61 is provided with a first loading fin 611, a first combining protrusion 612 and a first combining edge 613; the second hanging bracket 62 is provided with a second loading fin 621, a second combining protrusion 622 and a second combining edge 623; the guiding rod 63 is provided with a first supporting position 631 and a second supporting position 632; the docking plate 64 is provided with a docking groove 641 and a docking hole 642, wherein the first loading fin 611 and the second loading fin 621 are used to connect the guiding rod 63, the first combining protrusion 612 and the second combining protrusion 622 is used to connect with the docking groove 641 on the docking plate 64, the first bonding edge 613 and the second bonding edge 623 are used to be assembled with the shell 1, the first bonding edge 613 and the second bonding edge 623 can be connected with the rubber kit 12, and then assembled with the shell 1, and the shell 1 is correspondingly provided with an assembly groove 11; the first support position 631 is correspondingly connected to the mounting plate 65, the second support position 632 is connected to the first loading fin 611 or the second loading fin 621, and the two ends of the guide rod 63 are respectively connected to the shell 1 and the docking plate 64.

[0116] In some embodiments, the docking plate 64 is configured as a quadrilateral plate body, and multiple docking grooves 641 are provided along the width direction of the edge of the docking plate 64; the docking hole 642 and the upper end of the guide rod 63 are also configured as a gap assembly to allow the guide rod 63 to move flexibly and elastically to consume the vibration energy generated by the solenoid valve group 8.

[0117] In some embodiments, see Figure 12 The end of the force-guiding rod 63 near the housing 1 may also be provided with a column structure 335. The cross-sectional area of the end surface of the column structure 335 near the inner bottom wall of the housing 1 is smaller than the cross-sectional area of the end surface of the force-guiding rod 63 near the housing 1. This arrangement, on the one hand, is beneficial to the elastic deformation range of the force-guiding rod 63 itself, allowing it to shift and tilt with the vibration force, thereby reducing the contact constraint of the housing 1 on the force-guiding rod 63. On the other hand, it is beneficial to reduce the transmission path of vibration from the force-guiding rod 63 to the housing 1, allowing the skeleton assembly 3 to maximize the consumption of the vibration energy of the vibration source.

[0118] In this embodiment, the electric silent control box also includes an air connection component, see Figure 14The air connection assembly includes a double-ended air pipe plug connector 95, an air pipe connector nut 96, and a muffler 97. The double-ended air pipe plug connector 95 and the air pipe connector nut 96 are used to connect the solenoid valve group 8 and the housing 1. The solenoid valve group 8 includes multiple solenoid valves, and any solenoid valve is connected to a flexible straight air pipe 81. One end of the flexible straight air pipe 81 is sealed with the connection port of the solenoid valve, and the other end of the flexible straight air pipe 81 is sealed with the double-ended air pipe plug connector 95. The double-ended air pipe plug connector 95 and the air pipe connector nut 96 can connect the flexible straight air pipe 81 between the solenoid valve and the housing 1.

The muffler 97 is installed on the housing 1. Specifically, the outer cylindrical surface of the muffler 97 is threaded, and the mounting hole on the housing 1 is provided with a threaded hole. The muffler 97 is connected to the housing 1 by thread.

[0119] In some embodiments, the motor module 5 can be configured as an air pump motor.

The flexible bent air pipe 82 can be fitted on the inner wall surface of the shell 1. The flexible bent air pipe 82 is partially bent and arranged in the installation cavity of the shell 1, which is conducive to strengthening the compact structure.

[0121] To enhance the sound insulation, see Figure 14An inner wall liner 14 is provided in the shell 1, and the inner wall liner 14 is arranged on the inner bottom wall and the lateral inner wall of the shell 1. A board wall liner 21 is provided on the side of the cover plate 2 facing the inside of the shell 1. The inner wall liner 14 and the board wall liner 21 can be foam pads to enhance the sound insulation and noise reduction effect of the electric silent control box, which is conducive to ensuring the consistency and stability of the shock absorption and silent effect of the overall structure of the electric silent control box.

[0122] In this embodiment, after the cover plate 2 is assembled on the housing 1, it can abut against the frame assembly 3 and the loading frame assembly 6, so that the cover plate 2 and the housing 1 form upper and lower limit structures for the frame assembly 3 and the loading frame assembly 6. The upper and lower constraints established by the housing 1 and the cover plate 2 can enhance the stability of the frame assembly 3 and the loading frame assembly 6 and improve the reliability of the vibration energy absorption operation.

[0123] The electric silent control box provided in this embodiment can establish a first shock-absorbing and noise-reducing structure through the limiting connection between the limiting plate 72 and the slide member 15 in the connecting component 7, and the sealing ring 73 sealing the shell 1 and the connecting end face of the cover plate 2; establish a second shock-absorbing and noise-reducing structure by connecting the rubber kit 12 at the bottom of any bracket or hanger and the assembly groove 11 on the shell 1; connect the motor module 5 in the vibration source through the flexible adapter component 4 to establish a third shock-absorbing and noise-reducing structure; connect the force transmission rod 33 or the force guiding rod 63 through the fin with elastic capacity to absorb the vibration energy of the vibration source as the fourth shock-absorbing and noise-reducing structure; convert the kinetic energy of the vibration source into kinetic energy through the force transmission rod 33 or the force guiding rod 63 with elastic capacity to achieve the purpose of absorbing the vibration energy of the vibration source. As the fifth shock-absorbing and noise-reducing structure, the overall electric silent control box has good sound insulation and shock absorption and stability.

[0124] The electric silent control box provided in this embodiment adopts a detachable sliding combination, mortise and tenon combination, and snap-in connection mode. It is easy to assemble and disassemble, and convenient to maintain. The production and assembly process is simple, fast, efficient, and low-cost. It is also easy to inspect and test the finished product, convenient for quality control and repair and replacement of parts, and can ensure the consistency and stability of the shock-absorbing and silent effects.
