[0036] For details, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The present application provides a sound insulation sealing assembly 10, which is used to cooperate with the steering gear 40 and the front panel 20 of the automobile. The sound insulation sealing assembly 10 may include a sealing plug 11 and a fixed cover plate 12. The sealing plug 11 includes a sealing body 111, a sound insulation sealing rib 112 and a plurality of sheet metal sealing ribs 113. The sealing plug 11 has a first sealing surface 1101 and a steering hole 1102 opened on the first sealing surface 1101. The steering hole 1102 passes through the sealing body 111 along the axial direction of the sealing plug 11. The steering hole 1102 is used to allow the steering gear 40 to pass through. The sound insulation sealing rib 112 is arranged around the outer periphery of the first sealing surface 1101, and the sheet metal sealing rib 113 is arranged around the steering hole 1102 at intervals on the first sealing surface 1101. The fixed cover plate 12 is arranged on the side of the sealing plug 11 away from the first sealing surface 1101. The fixed cover plate 12 is used to be fixedly connected to the front panel metal 20 so as to abut the sheet metal sealing rib 113 against the front panel metal 20 and abut the sound insulation sealing rib 112 against the sound insulation pad 30 on the front panel metal 20.

[0037] It is understandable that the fixed cover plate 12 can fix the sealing plug 11 to the front wall sheet metal 20 of the automobile, so that the sheet metal seal abuts against the front wall sheet metal 20, and the sound insulation seal abuts against the sound insulation pad 30 on the front wall sheet metal 20. The sealing plug 11 can form an integral surrounding structure around the through hole of the front wall sheet metal 20 and on the sound insulation pad 30, so that the sealing plug 11 can not only ensure the dustproof and waterproof functions, but also have a sound insulation effect.

[0038] More specifically, if Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, in one embodiment, the sealing plug 11 further includes a fixing portion 115 and a plurality of steering sealing ribs 116. The sealing plug 11 has a second sealing surface 1104, and the second sealing surface 1104 is located on a side of the sealing body 111 away from the first sealing surface 1101. The steering sealing ribs 116 are arranged on the second sealing surface 1104 at intervals around the steering hole 1102. The fixing portion 115 is used to be fixedly connected to the steering gear 40 so that the steering sealing ribs 116 abut against the steering gear 40. In other words, the fixing portion 115 can fix the sealing body 111 to the steering gear 40, and the steering sealing ribs 116 can be sealed with the steering gear 40 to seal the gap between the steering gear 40 and the sealing plug 11, so as to prevent dust and water from entering the steering hole 1102 from the gap, thereby achieving dustproof and waterproof effects.

[0039] Preferably, if Figure 4 and Figure 6 As shown, in one embodiment, the fixing portion 115 includes a fixing ring body 1151 extending from the second sealing surface 1104 in a direction away from the sealing body 111, and the inner surface of the fixing ring body 1151 is recessed outward to form a clamping groove 1152, and the clamping groove 1152 is used to clamp with the steering gear 40. In this way, by clamping the steering gear 40 into the clamping groove 1152, the fixing ring body 1151 can surround the steering gear 40, further improving the dustproof and waterproof performance of the sealing plug 11.

[0040] Preferably, if Figure 5 As shown, in one embodiment, a plurality of sheet metal sealing ribs 113 are arranged concentrically at intervals on the first sealing surface 1101. Such an arrangement makes the sheet metal sealing ribs 113 and the front wall sheet metal 20 cooperate more evenly, and can obtain better dustproof and waterproof effects.

[0041] Preferably, if Figure 6As shown, in one embodiment, a plurality of the steering sealing ribs 116 are arranged concentrically at intervals on the second sealing surface 1104. Such an arrangement makes the steering sealing ribs 116 cooperate more evenly with the steering gear 40, and can obtain better dustproof and waterproof effects.

[0042] More specifically, if Figure 6 and Figure 7 As shown, in one embodiment, the sealing body 111 includes a first sealing portion 1111 and a second sealing portion 1112, the first sealing surface 1101 is located at the first sealing portion 1111, the second sealing surface 1104 is located at the second sealing portion 1112, and the size of the first sealing portion 1111 is larger than the second sealing portion 1112 to form a flange-shaped structure. The fixed cover plate 12 includes a fixed plate body 121 for fixed connection with the front wall sheet metal 20 and an annular plate body 122 extending from the fixed plate body 121 to the first sealing surface 1101. The fixed plate body 121 abuts against the first sealing portion 1111, and the annular plate body 122 surrounds the first sealing portion 1111. In this way, the sealing plug 11 can be fixed to the front wall sheet metal 20 by cooperating with the first sealing portion 1111 of the fixed cover plate 12. The annular plate body 122 can be sealed with the first sealing portion 1111 to improve the dustproof and waterproof performance between the fixed cover plate 12 and the sealing plug 11.

[0043] Preferably, if Figure 6 and Figure 7 As shown, in one embodiment, the fixed cover plate 12 has a plurality of installation holes 123 arranged at intervals, and the installation holes 123 are opened in the fixed plate body 121; the sealing plug 11 has a plurality of communication holes 1103 arranged at intervals, and the communication holes 1103 are opened in the first sealing surface 1101, and the communication holes 1103 correspond to the installation holes 123 one by one, and the communication holes 1103 and the installation holes 123 are used to pass bolts to be screwed with the front panel 20. In this way, the sound insulation sealing assembly 10 is fixed to the front panel 20 by bolts, which can make the installation structure of the sound insulation sealing assembly 10 more reliable, so as to improve the dustproof, waterproof and sound insulation performance of the sound insulation sealing assembly 10.

[0044] Alternatively, if Figure 3 and Figure 5 As shown, in one embodiment, the sealing plug 11 further includes a plurality of communication sealing portions 114 protruding from the first sealing surface 1101, and the communication sealing portions 114 are respectively arranged around the communication holes 1103. In this way, the communication sealing portions 114 can cooperate with the front panel 20 to seal the gap between the portion of the sealing body 111 near the communication hole 1103 and the sound insulation pad 30, thereby avoiding the problems of dust leakage, water leakage and sound leakage at this location.

[0045] Preferably, if Figure 5 As shown, in one embodiment, the communication sealing portion 114 is connected to the sound insulation sealing rib 112. Such a configuration can strengthen the structure of the communication sealing portion 114 and the sound insulation sealing rib 112 to further enhance the dustproof, waterproof and sound insulation performance of the portion of the sealing body 111 near the communication hole 1103.

[0046] Furthermore, if Figure 1 and Figure 2 As shown, the present application also provides a steering device, which may include a front panel 20, a sound insulation pad 30, a steering gear 40, and a sound insulation sealing assembly 10 as described above, wherein the sound insulation pad 30 is fixed to the front panel 20, the sealing plug 11 is arranged between the front panel 20 and the steering gear 40, and the sealing plug 11 is respectively sealed and matched with the front panel 20, the sound insulation pad 30 and the steering gear 40.
