[0061] As described in the background technology, when a vehicle is driving on the road, the rolling tires will bring dust, mud, water, stones, etc. into the cabin through the avoidance holes on the shock absorber tower, thereby polluting the cabin. The inventors have found that the reason for this problem is that there is no component on the shock absorber tower to cover the avoidance holes, resulting in the rolling tires bringing dust, mud, water, stones, etc. into the cabin through the avoidance holes on the shock absorber tower when the vehicle is driving on the road, thereby polluting the cabin.

[0062] In order to solve the above problems, the embodiments of the utility model provide a shock absorber tower assembly, a double wishbone suspension assembly and a vehicle, and add a shielding cover. By installing the shielding cover with the shock absorber tower, the shielding cover shields the avoidance hole of the shock absorber tower to prevent dust, mud, water, stones, etc. from entering the cabin through the avoidance hole of the shock absorber tower, thereby protecting the cabin from pollution and keeping the cabin clean.

[0063] The shock tower assembly, double wishbone suspension assembly and vehicle provided by the utility model embodiments are described in detail below in conjunction with specific embodiments.

[0064] Embodiment 1

[0065] The embodiment of the utility model provides a shock tower assembly, which is applied to a double wishbone of a double wishbone suspension assembly of a vehicle, and the double wishbone is swingably installed below the shock tower assembly.

[0066] like Figures 1 to 3 As shown, the shock tower assembly includes a shock tower 10 and a shielding cover 20. The shock tower 10 has an avoidance hole 101 (see Figure 2 The shielding cover 20 includes a shield body 21 and a connecting portion 22 connected to each other, the hardness of the shield body 21 is less than the hardness of the connecting portion 22, and the shield body 21 has an avoidance cavity 211 for avoiding the motion trajectory of the double fork arm swing (see Figure 3 As shown), the connection portion 22 is configured to be installed with the shock absorbing tower 10 so that the cover body 21 abuts against the shock absorbing tower 10 and blocks the avoidance hole 101.

[0067] The avoidance hole 101 is arranged at the top of the shock absorbing tower 10 . The avoidance hole 101 is constructed as an irregular hole and passes through the shock absorbing tower 10 . The avoidance hole 101 is used to avoid the double fork arm.

[0068] The shielding cover 20 may be a plastic cover or a metal cover (eg, an aluminum alloy cover or a steel cover).

[0069] The structure of the shielding cover 20 can be designed according to the movement trajectory of the double fork arm.

[0070] The avoidance cavity 211 corresponds to the avoidance hole 101 , is located above the avoidance hole 101 , and is open toward the avoidance hole 101 . The avoidance cavity 211 provides an avoidance space for the movement of the double fork arm, so that the double fork arm does not interfere with the shielding cover 20 during the movement.

[0071] The cover body 21 may be in contact with the inner wall of the escape hole 101 and with the top wall of the shock absorbing tower 10 .

[0072] The connection part 22 can be directly mounted on the shock tower 10, for example, the connection part 22 is mounted on the shock tower 10 by welding or clamping. The connection part 22 can also be mounted on the shock tower 10 through other components.

[0073] The hardness of the cover body 21 and the connecting portion 22 can be set according to actual needs.

[0074] The shock tower assembly provided by the embodiment of the utility model is provided with a shielding cover 20 installed with the shock tower 10, and the shielding cover 20 shields the avoidance hole 101 of the shock tower 10, thereby preventing dust, muddy water, stones, etc. from entering the cabin through the avoidance hole 101 of the shock tower 10, so that the cabin is free from pollution and the cabin is kept clean. At the same time, the possibility of stones being brought into the cabin to produce abnormal noise is avoided, which is conducive to maintenance and care.

[0075] By adding the shielding cover 20 to the shock absorbing tower 10, the cabin layout is made regular and the user experience is improved.

[0076] By making the hardness of the cover body 21 smaller than the hardness of the connecting portion 22, the force exerted by the shielding cover 20 on the shock tower 10 can be reduced, and the risk of abnormal noise at the contact point between the shielding cover 20 and the shock tower 10 can be effectively reduced when the vehicle body is twisted.

[0077] In a possible implementation, the cover body 21 and the connecting portion 22 are integrally formed by a two-color injection molding process.

[0078] The cover body 21 is a soft rubber component, and the connecting portion 22 is a hard rubber component.

[0079] In some examples, the shock tower 10 is made of aluminum alloy; the cover body 21 is made of thermoplastic vulcanizate (TPV); and the connection portion 22 is made of polypropylene, which is referred to as PP. By selecting thermoplastic vulcanizate as the material of the cover body 21, the cover body 21 and the shock tower 10 have good compatibility, which can effectively reduce the risk of abnormal noise at the contact part between the shielding cover 20 and the shock tower 10 when the vehicle body is twisted.

[0080] The contact area between the cover body 21 and the shock tower 10 is greater than the contact area between the connecting portion 22 and the shock tower 10. This arrangement can reduce the force of the shielding cover 20 on the shock tower 10, and effectively reduce the risk of abnormal noise at the contact point between the shielding cover 20 and the shock tower 10.

[0081] In a possible implementation, Figure 3 and Figure 4 As shown, the connection portion 22 includes a plurality of connection plates 22 a , which are arranged at intervals along the edge of the cover body 21 , and each connection plate 22 a is provided with a connection hole 22 b .

[0082] A mounting member 30 is installed in each connection hole 22 b , and the mounting member 30 can be installed with the shock tower 10 .

[0083] See also Figure 5As shown, the mounting member 30 is a plastic buckle, which includes a plastic screw 31 and a plastic nut 32. The plastic screw 31 is inserted into the plastic nut 32, and the plastic nut 32 is engaged with the shock tower 10. This arrangement facilitates the installation and removal of the shielding cover 20 and the shock tower 10. In other embodiments, the mounting member 30 may be a bolt and a nut, and the shielding cover 20 is fixed to the shock tower 10 by the bolt and the nut.

[0084] The plastic screw 31 is connected to the plastic nut 32 by threads. Before the plastic buckle is used, the plastic screw 31 is partially inserted into the plastic nut 32 .

[0085] The plastic nut 32 has a plurality of nut expansion feet 321, which are evenly distributed on the plastic nut 32 in the circumferential direction and enclose an inner diameter that is smaller than the inner diameter of the nut threaded portion. When the plastic screw 31 is fully inserted into the plastic nut 32, the nut expansion feet 321 are squeezed to expand and deform outward because the inner diameter enclosed by the plurality of nut expansion feet 321 is smaller than the inner diameter of the nut threaded portion.

[0086] See also Figure 6 As shown, the shock tower 10 is provided with a plurality of mounting holes 102, and the plurality of mounting holes 102 correspond one-to-one to the plurality of connecting holes 22b of the connecting portion 22, and the plastic nut 32 of the plastic buckle can be snapped into the mounting holes 102. In this embodiment, the connecting portion 22 includes 6 connecting plates 22a, and each connecting plate 22a is provided with a connecting hole 22b, that is, the connecting portion 22 has 6 connecting holes 22b, and the shock tower 10 is provided with 6 mounting holes 102, and the 6 mounting holes 102 are sequentially spaced along the edge of the avoidance hole 101, and the 6 mounting holes 102 correspond one-to-one to the 6 connecting holes 22b.

[0087] When the shock tower 10 and the shielding cover 20 are installed, first align the various connecting holes 22b of the connecting part 22 of the shielding cover 20 with the mounting holes 102 of the shock tower 10, then insert the plastic nuts 32 of the various plastic buckles into the mounting holes 102, then insert the cross screwdriver into the screw rotation groove 311, rotate the cross screwdriver, and the plastic screw 31 is completely inserted into the plastic nut 32. At this time, since the inner diameter surrounded by the multiple nut expansion feet 321 is smaller than the inner diameter of the nut threaded part, the nut expansion feet 321 will be squeezed to cause it to expand and deform outward, and be clamped and fixed to the shock tower 10.

[0088] When removing the shielding cover 20, insert the cross screwdriver into the screw rotation slot 311, and rotate the cross screwdriver to screw out the plastic screw 31. At this time, the nut expansion foot 321 is not squeezed by external force and returns to its original state, and the plastic nut 32 can be directly pulled out, that is, the shielding cover 20 can be removed from the shock tower 10.
