[0041] Preferably, if Figures 1 to 5 As shown, the portion of the cover body 112 exceeds the outer side wall of the guide portion 111 to form an outer edge of the cover body 112. The width of the outer edge can be greater than or equal to 3 mm. For example, the width of the outer edge can be 4 mm, 5 mm, 6 mm, etc., to ensure the clamping strength of the hole plug.

[0042] Preferably, if Figure 5 As shown, the guide portion 111 may include a plurality of guide claws 1111, and the plurality of guide claws 1111 are arranged at intervals along the circumference of the mounting hole. Thus, on the one hand, the waterproof hole plug 1 can be clamped and fixed to the mounting hole via the guide claws 1111; on the other hand, the guide claws 1111 are arranged at intervals along the circumference of the mounting hole, which can effectively improve the clamping stability between the waterproof hole plug 1 and the mounting hole.

[0043] Preferably, if Figure 5 As shown, the above-mentioned guide part 111 may also include a guide wall 1112. The guide wall 1112 is arranged between two adjacent guide claws 1111. The guide wall 1112 and the guide claws 1111 are arranged in a cylindrical shape, and the cylindrical shape is adapted to the shape of the mounting hole. On the one hand, the connection strength between the guide part 111 and the cover body 112 is ensured; on the other hand, the clamping stability between the guide part 111 and the mounting hole is further improved.

[0044] Optionally, the thickness of the cover body 112 may be greater than or equal to 4 mm to ensure the strength of the cover body 112 .

[0045] Preferably, if Figure 2 , Figure 4 and Figure 5 As shown, the support assembly may further include a reinforcing rib 113 , which is fixedly disposed on a side of the cover body 112 facing away from the soft waterproof assembly 12 , so as to improve the anti-deformation strength of the cover body 112 .

[0046] Preferably, if Figure 5 As shown, the reinforcing ribs 113 may be distributed in a grid pattern on a side surface of the cover body 112 facing away from the soft waterproof component 12 to ensure uniform distribution of the anti-deformation strength of the cover body 112 .

[0047] Preferably, the support assembly can be made of hard plastic, such as nylon plastic. Optionally, the cover body 112, the reinforcing ribs 113 and the guide portion 111 can be integrally injection molded.

In this way, the liquid falling on the waterproof hole plug 1 can be effectively guided away from the mounting hole, thereby reducing the probability of water entering the blocked mounting hole.

[0051] Optionally, the mounting hole may be a threading hole, a fixing hole or a positioning hole on the vehicle body sheet metal 2 .

[0052] Preferably, if Figures 2 to 4As shown, the waterproof flange 122 may include an outer bevel 1221 and an inner bevel 1222, one end of the outer bevel 1221 is connected to the edge of the covering layer 121, the other end of the outer bevel 1221 intersects with the inner bevel 1222, and the end of the inner bevel 1222 away from the intersection line of the outer bevel 1221 extends to the side of the guide portion 111 of the cover body 112. In this way, a thin wall is formed at the end of the waterproof flange 122 away from the covering layer 121, which can effectively improve the deformation sensitivity of the end of the waterproof flange 122 away from the covering layer 121, thereby improving the fit between the waterproof flange 122 and the vehicle body sheet metal 2, so as to further improve the sealing and waterproof properties of the waterproof hole plug 1 for sealing the mounting hole.

[0053] Preferably, if Figures 2 to 4 As shown, the included angle between the outer inclined surface 1221 and the inner inclined surface 1222 (ie, ∠γ shown in the figure) can be 25° to 35°, for example, ∠γ can be equal to 30°.

[0054] Preferably, if Figures 2 to 4 As shown, the angle between the outer bevel 1221 and the surface of the coating layer 121 (i.e., ∠α shown in the figure) can be 105° to 135°, for example, ∠α can be equal to 105°, 110°, 115°, 120°, 125°, 130° or 135°.

[0055] Preferably, the soft waterproof component 12 may be made of soft plastic, such as TPV.

[0056] Preferably, the soft waterproof component 12 can be integrally connected with the support component via secondary injection molding, so as to ensure the connection stability between the soft waterproof component 12 and the support component.

[0057] The embodiment of the second aspect of the present application also provides an automobile, comprising the waterproof hole plug 1 described in any of the above embodiments, and thus having all the beneficial technical effects of the waterproof hole plug 1, which will not be repeated here.
