Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle accessories, and in particular to a plug cover and a vehicle. BACKGROUND

[0002] As a key component of the basic performance of mechanical equipment, the sealing performance is crucial to ensure the safety and comfort of the equipment. In the manufacturing process, in order to meet various process requirements, the sheet metal of the mechanical equipment (including but not limited to vehicles) is usually designed with various types of holes, such as process holes, positioning holes and functional holes. Most of these holes are connected with the outside environment. If the sealing is not proper, it will cause the equipment to leak air or water, and the effect of isolating noise will also be greatly reduced, which directly affects the overall sealing performance of the equipment.

[0003] At present, high-temperature hot-melt plug covers are widely used in the industry to effectively seal these holes. However, the existing plug cover design is relatively simple, and there are some obvious shortcomings, such as large insertion force of the plug cover, which causes assembly difficulty.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be apparently and completely described in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0034] The present application provides a plug cover, please refer to Figure 1 , Figures 1 to 6 is a structural schematic view of the plug cover provided in the embodiments of the present application.

[0035] The plug cover 100 comprises a cover body 1, an intermediate body 2 and a plurality of clamping legs 3 (specifically, Figure 1The two clamping legs 3 are shown in the middle, and the plug cover 100 is used to block the hole 210. Taking the hole 210 in the sheet metal 200 of the vehicle as an example, the sheet metal 200 has opposite first and second sides 201 and 202, and the hole 210 communicates the first and second sides 201 and 202 (see Figure 5 and Figure 6 wherein, Figure 5 The plug cover 100 is cut from the opening 3121 in the middle, Figure 6 The plug cover 100 is cut from the notch groove 21 in the middle.

[0036] The cover body 1 is used to abut the first side 201 of the sheet metal 200, and the area of the cover body 1 is greater than the size of the hole 210, so as to ensure that the cover body 1 can completely cover the hole 210 and prevent liquid or gas from leaking from the edge of the hole 210. Of course, in order to enhance the sealing effect, a hot melt adhesive 300 can be provided between the cover body 1 and the sheet metal 200 (see Figure 5 ).

[0037] The intermediate body 2 is connected to one side of the cover body 1, and the intermediate body 2 is used to pass through the hole 210 in the sheet metal 200. The intermediate body 2 provides the plug cover 100 with the necessary physical support, so as to ensure that the plug cover 100 can smoothly pass through the hole 210 and be fixed on the sheet metal 200. The intermediate body 2 is provided with a notch groove 21 at the end away from the cover body 1 (in combination with Figure 4 ).

[0038] A plurality of clamping legs 3 are connected to the end of the intermediate body 2 away from the cover body 1 and are connected to the outer periphery of the intermediate body 2. The notch groove 21 is arranged between two adjacent clamping legs 3 ( Figure 1 Two notch grooves 21 are shown in the middle). When starting to assemble, the plug cover 100 is aligned with the hole 210 from the first side 201 of the sheet metal 200, with the end of the intermediate body 2 away from the cover body 1. Since the notch groove 21 is arranged between two adjacent clamping legs 3, this notch groove 21 weakens the connection strength between the clamping legs 3, so that the clamping legs 3 can be more easily deformed when inserted into the hole 210. When the plug cover 100 is inserted towards the hole 210, the clamping legs 3 are elastically deformed and contracted due to the extrusion of the inner wall of the hole 210. Due to the design of the notch groove 21, the force required for the plug cover 100 to be inserted is reduced, which improves the convenience of assembly. After the clamping legs 3 pass through the hole 210 and reach the second side 202 of the sheet metal 200, the clamping legs 3 are no longer extruded by the inner wall of the hole 210 and will automatically expand. The expanded clamping legs 3 abut the second side 202 of the sheet metal 200 (see Figure 6 ), which can effectively prevent the plug cover 100 from falling off during use, thereby ensuring the stability of the plug cover 100 when blocking the hole 210.

[0039] That is, in the technical solution of the present application, the notch groove 21 is arranged at the end of the intermediate body 2 away from the cover body 1 and between the two adjacent clamping legs 3, so that the connection strength between the clamping legs 3 is weakened. This makes the clamping legs 3 more easily deformed when inserted into the hole 210, thereby reducing the force of the plug cover 100 during insertion, and improving the assembly convenience. It can be understood that improving the assembly convenience of the plug cover 100 can prevent the clamping legs 3 from being stuck in the hole 210 due to difficult assembly, thereby reducing the repair cost.

[0040] In some embodiments, as shown in Figure 1 and Figure 4 , the notch groove 21 has two side walls 211 arranged opposite to each other in the circumferential direction of the intermediate body 2, and the two side walls 211 are away from each other in the direction of the cover body 1 towards the notch of the notch groove 21. In these embodiments, the closer to the notch, the farther the distance between the two side walls 211, and the more obvious the weakening effect on the connection strength. That is, the closer to the insertion end of the intermediate body 2, the weaker the connection strength between the clamping legs 3, and the more easily deformed when inserted into the hole 210, thereby further improving the assembly convenience. Specifically, the notch groove 21 can be a V-shaped groove, a U-shaped groove, etc.

[0041] In some embodiments, as shown in Figure 2 , the clamping leg 3 has a free end 31 away from the intermediate body 2, and the free end 31 includes a first portion 311 and a second portion 312 in the direction of surrounding the intermediate body 2, and the strength of the second portion 312 is less than that of the first portion 311. In these embodiments, the strength of the second portion 312 is less than that of the first portion 311, so that the second portion 312 can start deforming earlier when the clamping leg 3 is inserted into the hole 210, thereby reducing the insertion resistance of the clamping leg 3 as a whole. Thus, by weakening the strength of the clamping leg 3 itself, it is more easily deformed when inserted into the hole 210, thereby further reducing the force of the plug cover 100 during insertion and improving the assembly convenience.

[0042] It can be understood that there are various ways to form the second portion 312 with a strength less than that of the first portion 311, such as punching holes on the second portion 312.

[0043] In some embodiments, as shown in Figure 2 , the second portion 312 is provided with an opening 3121 extending from the end surface away from the intermediate body 2 to the intermediate body 2. In these embodiments, the opening 3121 is provided on the second portion 312, so that the second portion 312 is more easily deformed when subjected to an external force, thereby reducing the resistance of the clamping leg 3 when inserted into the hole 210. This makes the assembly process smoother, reduces the insertion force, and improves the assembly convenience. Specifically, the inner wall of the opening 3121 is arc-shaped.

[0044] In some embodiments, the thickness of the second portion 312 is less than the thickness of the first portion 311. In these embodiments, the thickness of the second portion 312 is reduced, reducing its rigidity, so that the card edge 3 is easier to deform when inserted into the hole 210, reducing the insertion force and improving the convenience of assembly.

[0045] In some embodiments, see Figure 1 and Figure 2 , the outer peripheral side of the intermediate body 2 is provided with a reinforcing rib 4, which is used to abut against the inner wall of the hole 210 (see Figure 5 and Figure 6 ). In these embodiments, the reinforcing rib 4 increases the structural rigidity of the intermediate body 2, so that the intermediate body 2 is not easily deformed, which helps to improve the overall strength of the plug 100 and ensure its reliability during use. In addition, the design of the reinforcing rib 4 makes the contact between the intermediate body 2 and the inner wall of the hole 210 more intimate, reducing the gap between the intermediate body 2 and the inner wall of the hole 210. The reinforcing rib 4 abutting against the inner wall of the hole 210 can reduce the amount of intermediate body 2 shaking in the hole 210, ensuring that the plug 100 is more stable during use. This helps to prevent poor sealing or falling off caused by shaking.

[0046] In some embodiments, see Figure 2 , the reinforcing rib 4 is a plurality of Figure 2 four reinforcing ribs 4 are shown), and the plurality of reinforcing ribs 4 are arranged on the outer periphery of the intermediate body 2 along the circumferential direction of the intermediate body 2. In these embodiments, the plurality of reinforcing ribs 4 are distributed along the circumferential direction of the intermediate body 2, so that the intermediate body 2 has sufficient rigidity in all directions, enhancing the stability of the overall structure. In addition, since the plurality of reinforcing ribs 4 abut against the inner wall of the hole 210, multiple contact points are provided, reducing the amount of intermediate body 2 shaking in the hole 210, ensuring that the plug 100 is more stable during use.

[0047] In some embodiments, see Figure 1 , Figure 2 and Figure 4 , the reinforcing rib 4 and the notch groove 21 are arranged along the axial direction of the intermediate body 2. In these embodiments, the reinforcing rib 4 and the notch groove 21 are arranged along the axial direction of the intermediate body 2, i.e. the reinforcing rib 4 is arranged at the region where the strength of the intermediate body 2 is weakened. This can ensure the strength of the intermediate body 2 while the notch groove 21 is arranged, preventing the intermediate body 2 from deforming excessively at these positions, and ensuring the stability and reliability of the overall structure.

[0048] In some embodiments, see Figure 2 and Figure 5, part of the reinforcing rib 4 and the second part 312 are arranged along the axial direction of the intermediate body 2. In these embodiments, the second part 312 of the clamping leg 3 is weak in strength due to the reduced thickness or the opening 3121, and is prone to deformation when inserted into the hole 210. By arranging the reinforcing rib 4 on the intermediate body 2, additional support can be provided to limit the maximum deformation displacement position of the clamping leg 3, prevent excessive deformation of the clamping leg 3 during insertion, and thus maintain the structural integrity of the clamping leg 3, ensuring the stability and reliability of the overall structure.

[0049] In some embodiments, see Figure 5 and Figure 6 , the reinforcing rib 4 extends along the axial direction of the intermediate body 2, and the reinforcing rib 4 is connected to the cover body 1. In these embodiments, the reinforcing rib 4 extends along the axial direction of the intermediate body 2 and plays a guiding role when inserted into the hole 210, reducing the amount of shaking between the body structure of the plug 100 and the hole 210 of the sheet metal 200, ensuring that the intermediate body 2 is centered with the center of the hole 210, and achieving the automatic centering function of the plug 100 when assembled into the hole 210, reducing the deviation during assembly, preventing the plug 100 from being assembled to the limit state or even causing the plug 100 to fall off after assembly, thereby saving the adjustment and repair labor costs caused by the misassembly of the plug 100, and also avoiding poor sealing caused by misassembly of the plug 100. The reinforcing rib 4 is connected to the cover body 1, and the reinforcing rib 4 plays a role in strengthening the strength of the cover body 1, preventing the cover body 1 from being squeezed, pulled, deformed, or even damaged during assembly and after assembly, and ensuring that the assembly state and sealing effect of the plug 100 are excellent.

[0050] In some embodiments, see Figure 3 , Figure 5 and Figure 6, the cover body 1 comprises a first skirt 11 and a second skirt 12, the first skirt 11 is connected around the outer periphery of the intermediate body 2, the first skirt 11 is inclinedly arranged from the intermediate body 2 to the direction away from the clamping leg 3, and the second skirt 12 is connected to the first skirt 11 and is inclinedly arranged from the first skirt 11 to the direction away from the clamping leg 3. In these embodiments, the first skirt 11 is inclinedly arranged from the intermediate body 2 to the direction away from the clamping leg 3, and the second skirt 12 is connected to the first skirt 11 and is inclinedly arranged from the first skirt 11 to the direction away from the clamping leg 3, that is, the first skirt 11 extends outward while moving away from the clamping leg 3 structure, and the second skirt 12 extends outward while moving toward the clamping leg 3 structure, and one end of the second skirt 12 away from the first skirt 11 abuts against the first side 201 of the metal plate 200. This shape lengthens the length of the lip structure (i.e., the first skirt 11 and the second skirt 12) of the cover body 1, so that the lip structure has better elasticity and is easier to restore to its original shape after being subjected to external force. During assembly and after being assembled into the hole 210, the lip structure can be restored to its original shape to the greatest extent after being subjected to assembly pressing force and support force of the metal plate 200, so as to ensure that the lip structure does not warp and tightly abuts against the metal plate 200, thereby enabling the plug-in cover 100 to provide good sealing performance for the hole 210 and preventing water, gas, and sound from leaking.

[0051] In some embodiments, see Figure 4 and Figure 5 The intermediate body 2 comprises a corner portion 22 and a connecting portion 23, the connecting portion 23 is connected between the corner portion 22 and the cover body 1, the connecting portion 23 is connected to the clamping leg 3 on the side close to the corner portion 22, and the corner portion 22 has a guide surface 221. In these embodiments, the connecting portion 23 is connected to the clamping leg 3 on the side close to the corner portion 22, and the connecting portion 23 is connected between the corner portion 22 and the cover body 1, that is, the corner portion 22 is arranged at the end of the intermediate body 2 away from the cover body 1. During assembly, the corner portion 22 is first assembled into the hole 210, thereby playing a role of pre-positioning and guiding and avoiding misassembly, failure of the clamping leg 3 to be clamped in place, and falling off of the plug-in cover 100. At the same time, the arrangement of the corner portion 22 reduces the moment of force of the clamping leg 3 acting on the metal plate 200 and increases the clamping force of the clamping leg 3 on the metal plate 200, so that the plug-in cover 100 is not easy to fall off, and the greater clamping force makes the cover body 1 more closely abut against the metal plate 200, thereby achieving better sealing effect.
