Detailed description

[0032] The following provides a detailed description of the specific embodiments of the present disclosure in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and do not limit the present disclosure.

[0033] In the present disclosure, unless otherwise specified, the orientation terms such as "inside" and "outside" are relative to the contour of the corresponding component itself. In addition, the terms "first", "second", etc. used in the present disclosure are used to distinguish one element from another, and do not have sequentiality and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be construed as a limitation of the present disclosure.

[0034] According to some embodiments of the present disclosure, a vehicle sealing structure is provided. Referring to Figures 1 to 5 as shown, the vehicle includes a vehicle door 100 and a vehicle body 200. The vehicle door 100 has an inner door panel 4, and the vehicle body 200 includes a body side panel 3. The vehicle sealing structure includes a first seal 1 and a clamping member 2. The first seal 1 includes a connected base body 11 and a deformation portion 12. One end of the clamping member 2 is clamped with the base body 11, and the other end is clamped with the body side panel 3. The base body 11 is used to abut and seal with the body side panel 3, and the deformation portion 12 abuts and seals with the inner door panel 4. A preset gap 20 is maintained between the clamping member 2 and the base body 11.

[0035] Through the above technical solution, in the vehicle sealing structure provided by the present disclosure, the vehicle sealing structure includes a first seal 1 and a clamping member 2. The first seal 1 includes a base body 11 and a deformation portion 12. One end of the clamping member 2 is clamped with the base body 11, and the other end is clamped with the body side panel 3. Since a preset gap 20 is maintained between the clamping member 2 and the base body 11, the clamping member 2 can be prevented from squeezing the base body 11. In this way, after the base body 11 is installed on the body side panel 3, it can remain in an undeformed state, preventing the base body 11 from being fatigued and damaged due to the continuous squeezing force of the clamping member 2, and prolonging the service life of the first seal 1. In addition, since a preset gap 20 is maintained between the clamping member 2 and the base body 11, there is always a gap between the clamping member 2 and the base body 11 when the vehicle door 100 is opened or closed. In this way, the base body 11 can be prevented from being continuously squeezed by the clamping member 2. When the vehicle door is closed, the first seal 1 only bears the squeezing force applied by the vehicle door 100, preventing the first seal 1 from warping due to the double squeezing of the clamping member 2 and the vehicle door 100, ensuring that the first seal 1 effectively abuts against both the vehicle door 100 and the body side panel 3, thereby playing an effective sealing role to ensure that the first seal 1 has a good sealing effect.

[0036] In the present disclosure, referring to Figure 3As shown in , the deformation portion 12 may include an arc segment 13 and a guide segment 14 connected to each other. The arc segment 13, the guide segment 14 and the base 11 are enclosed to form a deformable cavity 10. The wall thickness of the deformable cavity 10 is uniform, easy to deform and conducive to lightweight. The inner concave surface of the arc segment 13 faces the body side panel 3, and the guide segment 14 is provided with a groove 141 on the side facing the body side panel 3. The connection between the arc segment 13 and the guide segment 14 is used to abut against the door inner panel 4. In this way, when the door 100 changes from an open state to a closed state, the door inner panel 4 gradually squeezes the arc segment 13, so that the side surfaces on both sides of the groove 141 gradually fit together due to the squeezing effect, thereby guiding the deformation direction of the deformation portion 12, avoiding fatigue damage of the deformation portion 12, and allowing the deformation portion 12 to maintain good sealing performance.

[0037] In some embodiments of the present disclosure, reference Figure 3 As shown in , the side of the base 11 away from the deformation portion 12 may be provided with an opening 110 and formed with a mounting cavity 111. The clamping member 2 includes a first clamping portion 21 and a second clamping portion 23 connected to each other. The first clamping portion 21 passes through the opening 110 and is clamped in the mounting cavity 111, and forms a preset gap 20 with the mounting cavity 111. The second clamping portion 23 is located outside the mounting cavity 111 and is clamped with the vehicle body side 3. In the above technical solution, the opening 110 is connected with the mounting cavity 111 to clamp the first clamping portion 21 in the mounting cavity 111 through the opening 110. Due to the preset gap 20, when the first clamping portion 21 cooperates with the mounting cavity 111, the first clamping portion 21 will not exert a pressing effect on the mounting cavity, that is, the base 11 will not be squeezed, thereby preventing the base 11 from being fatigued and damaged due to continuous squeezing force.

[0038] In some embodiments of the present disclosure, reference Figure 3 As shown in the figure, the first sealing member 1 may include a first sealing lip 15 and a second sealing lip 16, and the first sealing lip 15 and the second sealing lip 16 are respectively located on opposite sides of the base 11, and when the first sealing lip 15 and the second sealing lip 16 are both in contact with the vehicle body side 3, the first clamping portion 21 and the mounting cavity 111 form a preset gap 20. In this way, when the vehicle door 100 is closed, the first sealing lip 15 and the second sealing lip 16 both abut against the vehicle body side panel 3, and the connection between the arc section 13 and the guide section 14 abuts against the door inner panel 4, thereby sealing the vehicle door 100 and the vehicle body side panel 3. At this time, since the first clamping portion 21 and the mounting cavity 111 form a preset gap 20, the side walls of the mounting cavity 111 close to the first sealing lip 15 and the second sealing lip 16 are prevented from being squeezed, causing the first sealing lip 15 and the second sealing lip 16 to warp. In this way, the first sealing lip 15 and the second sealing lip 16 can be stably fitted with the vehicle body side panel 3 to ensure that the first sealing component 1 plays a good sealing role.

[0039] Among them, the interference amount between the second sealing lip 16 and the vehicle body side wall 3 can be 0.8 mm to 1.2 mm. Exemplarily, it can be 0.8 mm, 1 mm or 1.2 mm, etc., so that the second sealing lip 16 can better abut and seal against the vehicle body side wall 3. In the present disclosure, the interference amount between the second sealing lip 16 and the vehicle body side wall 3 can be selected as any suitable value within the range of 0.8 mm to 1.2 mm according to actual requirements, and the present disclosure does not make specific limitations thereto.

[0040] In addition, the interference amount between the deformation part 12 and the vehicle door inner panel 4 can be 2 mm to 2.5 mm. Exemplarily, it can be 2 mm, 2.2 mm or 2.5 mm. In this way, it is avoided that the interference amount between the deformation part 12 and the vehicle door inner panel 4 is too large, resulting in the leakage of the first seal 1 and affecting the appearance. At the same time, it is avoided that the reaction force of the first seal 1 on the vehicle door inner panel 4 is too large, affecting the closing of the vehicle door, and ensuring effective sealing. Similarly, the interference amount between the deformation part 12 and the vehicle door inner panel 4 can be selected as any suitable value within the range of 2 mm to 2.5 mm according to actual requirements, and the present disclosure does not make specific limitations thereto.

[0041] In some embodiments of the present disclosure, referring to Figure 3 as shown in, the first sealing lip 15 can be configured as an arc structure. The first sealing lip 15 includes a first abutting portion 151 and a second abutting portion 153. Both the first abutting portion 151 and the second abutting portion 153 abut and seal against the vehicle body side wall 3, and the first abutting portion 151 and the second abutting portion 153 respectively protrude from the base body 11 in different directions toward the vehicle body side wall 3. An arc surface 152 recessed away from the vehicle body side wall 3 is formed between the first abutting portion 151 and the second abutting portion 153. By such a setting, the first abutting portion 151 and the second abutting portion 153 can respectively abut against different parts of the vehicle body side wall 3, so that the vehicle body side wall 3 can play a better supporting role on the first sealing lip 15, thereby improving the installation stability of the first seal 1. In addition, through the formation of the arc surface 152, when both the first abutting portion 151 and the second abutting portion 153 abut and seal against the vehicle body side wall 3, a cavity will be formed between the arc surface 152 and the vehicle body side wall 3. When being squeezed, the first sealing lip 15 will deform close to the vehicle body side wall 3, thereby driving the first abutting portion 151 and the second abutting portion 153 to better abut against the vehicle body side wall 3, improving the sealing effect. Since the arc structure has better resilience, it is beneficial for the first sealing lip 15 to quickly recover elastic deformation after the external force disappears.

[0042] In some embodiments of the present disclosure, referring to Figure 3As shown in the figure, a first buffer groove 17 may be formed between the first abutting portion 151 and the base body 11. The first buffer groove 17 is recessed toward the vehicle body side wall 3. Thus, when the vehicle door 100 is closed and presses the first seal 1, the first buffer groove 17 can guide the first abutting portion 151 to approach the base body 11.

[0043] In some other embodiments of the present disclosure, a second buffer groove 18 may be formed between the second abutting portion 153 and the base body 11. The second buffer groove 18 is recessed away from the vehicle body side wall 3. Thus, when the vehicle door 100 is closed and presses the first seal 1, the second buffer groove 18 can guide the second abutting portion 153 to approach the base body 11.

[0044] In some other embodiments of the present disclosure, a first buffer groove 17 may be formed between the first abutting portion 151 and the base body 11. The first buffer groove 17 is recessed toward the vehicle body side wall 3; and a second buffer groove 18 is formed between the second abutting portion 153 and the base body 11. The second buffer groove 18 is recessed away from the vehicle body side wall 3. In this way, when the first seal 1 is subjected to the extrusion of the vehicle door, the first abutting portion 151 and the second abutting portion 153 can approach the base body 11 in the same direction, avoiding tearing between the first abutting portion 151, the second abutting portion 153 and the base body 11, and extending the service life of the first seal 1.

[0045] In some embodiments of the present disclosure, referring to Figure 3 As shown in the figure, the numerical range of the preset gap 20 is t, where 0.3 mm ≤ t ≤ 0.7 mm. Exemplarily, the value of t can be 0.3 mm, 0.5 mm or 0.7 mm, etc. In this way, it can avoid the first clamping portion 21 from squeezing the bottom of the installation cavity 111, and at the same time enable the base body 11 to effectively abut against the vehicle body side wall 3 to ensure the sealing performance. In the present disclosure, the preset gap 20 can be selected as any suitable value within the range of 0.3 mm ≤ t ≤ 0.7 mm according to actual needs, and the present disclosure does not make specific limitations on this.

[0046] In some embodiments of the present disclosure, referring to Figure 3 As shown in the figure, the vehicle sealing structure may further include a gasket 5. The clamping member 2 further includes an extension arm 22. The extension arms 22 are respectively connected to two opposite sides of the first clamping portion 21. The gasket 5 is sleeved on the second clamping portion 23 and clamped between the extension arm 22 and the vehicle body side wall 3. In the above technical solution, the gasket 5 has elasticity. By using the gasket 5 to fill the gap between the extension arm 22 and the vehicle body side wall 3, it can play a role in strengthening the seal. At the same time, the gasket 5 can reliably abut against both the extension arm 22 and the vehicle body side wall 3, improving the fixing stability of the clamping member 2.

[0047] In the present disclosure, referring to Figure 3As shown, the vehicle body side panel 3 may include a connected first connecting plate 31 and a second connecting plate 32. There is a preset angle between the first connecting plate 31 and the second connecting plate 32, and a fillet R is formed at the preset angle. The fillet corresponds to the first sealing lip 15. In order to enable the first seal 1 to have a larger installation area, the range of the preset angle can be set to 110° - 130°. Exemplarily, the preset angle can be 110°, 120° or 130°. In addition, in order to make the clamping member 2 better clamped with the vehicle body side panel 3, R ≤ 8 mm can be set. Exemplarily, the value of R can be 5 mm, 6 mm or 8 mm, improving the firmness of the installation of the clamping member 2.

[0048] In some embodiments of the present disclosure, referring to Figure 1 , Figure 2 and Figure 4 as shown, the vehicle sealing structure may further include a second seal 6. The second seal 6 is installed on the door frame 301, and the first seal 1 is installed on the outer panel 302 of the vehicle body side panel 3. Among them, the first seal 1 and the second seal 6 partially overlap. In the above technical solution, the first seal 1 can be used as a water stop strip of the vehicle body side panel 3, playing a role in preventing impurities such as rainwater, snow water, muddy water, dust, and iron filings from entering the vehicle body interior. The second seal 6 can be used as a door frame sealing strip. In addition, in order to improve the sealing performance, the overlapping amount of the first seal 1 and the door seal can be set to > 50 mm, ensuring more comprehensive sealing between the vehicle body side panel 3 and the door 100.

[0049] In some embodiments of the present disclosure, referring to Figure 1 and Figure 2 as shown, a separation gap is formed between the first seal 1 and the door seal. The numerical range of the separation gap is 5 mm - 10 mm. Among them, the separation gap is the distance between the first seal 1 and the second seal 6 along the length direction of the vehicle B-pillar at the top position of the vehicle B-pillar. Exemplarily, the numerical value of the separation gap can be 5 mm, 8 mm or 10 mm. In this way, interference between the first seal 1 and the second seal 6 at the top position of the vehicle B-pillar can be avoided, enabling the first seal 1 and the second seal 6 to effectively abut against the vehicle body side panel 3, ensuring the sealing performance. In the present disclosure, the separation gap between the first seal 1 and the second seal 6 can be selected as any suitable numerical value in the range of 5 mm - 10 mm according to actual needs, and the present disclosure does not make specific limitations on this.

[0050] In some embodiments of the present disclosure, referring to Figure 4As shown in the figure, the second sealing member 6 may include a mounting portion 61 and a foaming portion 62 that are connected to each other, the mounting portion 61 being sealingly connected to the vehicle body side panel 3, and the foaming portion 62 being used for abutting and sealing with the door inner panel 4, wherein at least two ridges 68 are provided on the side of the foaming portion 62 away from the mounting portion 61, the ridges 68 extending along the length direction of the second sealing member 6, and the ridges 68 are arranged at intervals along the circumference of the foaming portion 62 and abut against the door inner panel 4. Among them, the foaming portion 62 has a second buffer cavity 30, and a first dividing line 50 and a second dividing line 60 are provided between the foaming portion 62 and the mounting portion 61. The first dividing line 50 and the second dividing line 60 are located on opposite sides of the length direction of the first buffer cavity 40. The dividing line between the foaming portion 62 and the mounting portion 61 is formed by the first dividing line 50 and the second dividing line 60. Among them, the mounting portion 61 can be made of a dense rubber material, and the foaming portion 62 can be made of a foam rubber material. When the second sealing member 6 is subjected to an extrusion force, it will be deformed at the first dividing line 50 and the second dividing line 60. In other words, the deformation direction of the foaming portion 62 is guided by the first dividing line 50 and the second dividing line 60. In this way, when the vehicle door 100 is closed, the second sealing member 6 is deformed as a whole at the first dividing line 50 and the second dividing line 60, which is conducive to a better fit between the vehicle door 100 and the second sealing member 6, and improves the overall effect of the vehicle body and the vehicle door 100 after the vehicle door 100 is closed.

[0051] It should be noted that, in actual applications, the deformation direction of the foaming portion 62 can be changed by changing the positions of the first dividing line 50 and the second dividing line 60, thereby changing the contact position between the foaming portion 62 and the door inner panel 4, so as to adapt to the sealing requirements between different types of door inner panels 4 and the vehicle body periphery 3.

[0052] In the present disclosure, due to the provision of the convex strips 68, when the vehicle door 100 is closed, a vacuum area is formed in the area enclosed by the two convex strips 68 and the vehicle door inner panel 4, so that the foaming portion 62 is stably abutted against the vehicle door inner panel 4 through the vacuum adsorption effect, ensuring that the foaming portion 62 will not be separated from the abutment with the vehicle door inner panel 4 when deformed by extrusion, so that the second sealing member 6 has a stable sealing performance, wherein the number of the convex strips 68 can be two, three or four, so that when the vehicle door 100 is closed, a vacuum area will be formed between two adjacent convex strips 68 and the vehicle door inner panel 4, thereby improving the reliability of the abutment between the foaming portion 62 and the vehicle door inner panel 4. Of course, the number of the convex strips 68 can be flexibly set according to actual usage requirements, and the present disclosure does not impose any restrictions.

[0053] In some embodiments of the present disclosure, reference Figure 4 As shown in , the spacing between two adjacent convex strips 68 may be 2 mm to 6 mm. For example, the spacing between the first protrusion 68 and the second protrusion 69 may be 2 mm, 4 mm or 6 mm, etc., and the present disclosure does not impose any specific limitation on this.

[0054] In addition, the height of the rib 68 may be f, and 1 mm ≤ f ≤ 1.2 mm. Exemplarily, f may be 1 mm, 1.1 mm, 1.2 mm, etc., and the present disclosure does not make specific limitations thereto.

[0055] In addition, the width of the rib 68 may be g, and 1.4 mm ≤ g ≤ 1.6 mm. Exemplarily, the value of g may be 1.4 mm, 1.5 mm, 1.6 mm, etc., and the present disclosure does not make specific limitations thereto.

[0056] In some embodiments of the present disclosure, as shown in Figure 4 a first buffer cavity 40 is formed between the foaming portion 62 and the mounting portion 61. A serrated portion 401 is provided on the cavity wall of the first buffer cavity 40 close to the vehicle body side wall 3. In the above technical solution, the first buffer cavity 40 increases the deformation effect, which is beneficial to the elastic deformation of the second seal 6 after being pressed. Among them, the serrated portion 401 includes a plurality of serrations arranged at intervals. By providing the serrations, when the foaming portion 62 is squeezed, the contact area between the two side walls of the first buffer cavity 40 is too large, which will cause friction and generate abnormal noises. Among them, the height of the serrations may be 0.3 mm to 0.7 mm. Exemplarily, it may be 0.3 mm, 0.5 mm or 0.7 mm. In addition, the distance between two adjacent serrations may be 0.6 mm to 1 mm.
