DETAILED DESCRIPTION
[0027] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation modes described herein are only used to illustrate and explain the present invention, and the protection scope of the present invention is not limited to the specific implementation modes described below.
[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] In the description of the present invention, some directional words are involved to clearly illustrate the technical solution of the present invention, for example: "up, down, left, right" are the meanings of the directions normally indicated by the A-pillar exterior panel and the side panel bright strip when assembled in the car, "outside" refers to the direction from the side panel to the inside of the car, and "inside" refers to the direction from the inside of the car to the side panel. It should be understood that the directional terms are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features.
[0031] In order to better understand the technical solution of the utility model, some of the terms appearing below are explained. In the following description, "static interference" refers to the conflict caused by two or more parts or components occupying the same position at the same time during the mechanical assembly process. Similarly, "static interference sealing" refers to a technical method in which two or more contact surfaces produce a certain interference under static conditions (i.e., when there is no external power or pressure) during the mechanical assembly process, thereby achieving a sealing effect. "Static interference connection" refers to the situation in which two or more parts or components are in a static state (i.e., without motion or external force) during the mechanical assembly process. Due to the specific geometric shape or size in the design, they produce a certain interference during assembly, that is, they occupy the same position or space at the same time, thereby forming a specific connection relationship.
[0032] refer to Figure 1 and Figure 2The utility model provides a frameless door sealing structure, an A-pillar exterior panel assembly 1 and a side panel bright strip 2. The A-pillar exterior panel assembly 1 includes an A-pillar exterior panel 101 and an A-pillar exterior panel bracket 102 connected to the A-pillar exterior panel 101. The side panel bright strip 2 includes a top panel bright strip corner 201 and a side panel bright strip corner 202 connected to the top panel bright strip corner 201. Specifically, the main body of the A-pillar exterior panel 101 is fixedly connected to the outside of the A-pillar exterior panel bracket 102, and the corner of the front end of the A-pillar exterior panel 101 is not fixedly connected to the A-pillar exterior panel bracket 102. The two are abutted against each other in a natural state so that the external structure can be inserted, thereby, a plug-in gap can be formed between the corner of the A-pillar exterior panel 101 and the A-pillar exterior panel bracket 102. The top strip bright trim corner 201 is inserted into the insertion gap, squeezing the A-pillar exterior panel bracket 102 and the A-pillar exterior panel 101 to deform in a direction away from each other. Since the top strip bright trim corner 201 is made of a flexible material and has a large deformation capacity, while the A-pillar exterior panel 101 is made of a hard material and has a weak deformation capacity, when the top strip bright trim corner 201 is inserted into the insertion gap, the A-pillar exterior panel 101 can only produce a small deformation or no deformation, and the top strip bright trim corner 201 is caused to deform in a direction close to the A-pillar exterior panel bracket 102, and at the same time, the side panel bright trim corner 202 fixedly connected to the top strip bright trim corner 201 is driven by the top strip bright trim corner 201 to deform inward to a certain extent. Since the side panel bright trim corner 202 is made of a hard material, the side panel bright trim corner 202 produces a small deformation or no deformation. Therefore, when the top strip bright trim corner 201 is inserted between the A-pillar exterior panel 101 and the A-pillar exterior panel bracket 102 and continuously inserted backward, the A-pillar exterior panel 101 limits the top strip bright trim corner 201 from deforming outward, and the side panel bright trim corner 202 limits the top strip bright trim corner 201 from deforming inward. The fixed connection point between the A-pillar exterior panel 101 and the A-pillar exterior panel bracket 102 limits the tendency of the top strip bright trim corner 201 to move backward. Under the action of multiple interferences, the displacement of the top strip bright trim corner 201 in all directions is limited, so that a static interference seal can be formed at the ends of the A-pillar exterior panel assembly 1 and the side panel bright strip 2. At this time, refer to Figure 2 It can be seen that the face difference of the A-pillar outer panel 101 is slightly higher than the face difference of the side bright trim strip joint angle 202, and the face difference can be 1.5mm. The above face difference can make up for the manufacturing tolerance and visually present a three-dimensional sense, thereby reflecting the exquisiteness of the interior decoration design, and the smaller assembly face difference can reduce the aerodynamic noise. In the above description, "front" refers to the direction of the A-pillar outer panel 101 pointing to the side bright strip 2, and "rear" refers to the direction of the side bright strip 2 pointing to the A-pillar outer panel 101.
[0033] In this embodiment, the A-pillar exterior panel bracket 102 includes an A-pillar flexible seal 1021, which is a rubber coating film of the A-pillar exterior panel bracket 102, and the A-pillar flexible seal 1021 is mainly arranged on the side of the A-pillar exterior panel bracket 102 close to the side outer panel 4 and the A-pillar exterior panel 101. Specifically, the A-pillar flexible seal 1021 is secondary injection molded on the A-pillar exterior panel bracket 102, and its material can be a rubber elastic part, such as TPU or TPE material. The A-pillar flexible seal 1021 mainly covers the upper contour edge of the A-pillar exterior panel bracket 102. In the fixed connection between the A-pillar exterior panel 101 and the A-pillar exterior panel bracket 102, when the inner side of the upper contour edge of the A-pillar exterior panel 101 abuts against the outer side of the upper contour edge of the A-pillar exterior panel bracket 102 wrapped with the A-pillar flexible seal 1021, it has strong sealing and vibration reduction and noise prevention effects.
[0034] refer to Figure 1 and Figure 7 The A-pillar flexible seal 1021 on the side of the A-pillar outer trim 101 of the A-pillar outer trim bracket 102 is formed with an arc portion. Figure 1 In the viewing direction, the tip of the A-pillar outer trim 101 transitions upward in an arc shape, and the horizontal plane where the upper end surface of the A-pillar flexible seal 1021 is located is higher than the horizontal plane where the upper end surface of the A-pillar outer trim bracket 102 is located, so that when the upper end surface of the A-pillar outer trim bracket 102 is fixedly connected to the side outer panel 4, the above-mentioned A-pillar flexible seal 1021 can be closely attached to the side outer panel 4 to form a sealing defense line. Figure 6 The end of the top strip bright trim corner 201 away from the side panel bright trim corner 202 is formed as an interference angle, which is a structure on the top strip bright trim corner 201 that is not covered and connected by the side panel bright trim corner 202, and the inner side of the top strip bright trim corner 201 is formed with an arc structure, which is respectively connected to the inner side surface and the lower bottom surface of the top strip bright trim corner 201. The "inner", "outer", "upper" and "lower" in the above description are Figure 6 The meaning of the direction normally indicated by the center side bright strip is by analogy.
[0035] Based on the above embodiment, in the assembly of the A-pillar exterior panel assembly 1 and the side panel bright strip 2, the interference corner of the top strip bright strip corner 201 is inserted between the front end corner of the A-pillar exterior panel 101 and the A-pillar exterior panel bracket 102, and the A-pillar exterior panel bracket 102 is covered with an A-pillar flexible seal 1021. At this time, the inner side surface of the corner of the A-pillar exterior panel 101 is against the outer side surface of the interference corner, and the interference corner is squeezed toward one side of the A-pillar exterior panel bracket 102. Figure 1 and Figure 2The top strip bright trim corner 201 interferes with the arc portion of the A-pillar flexible seal 1021 , so that the top strip bright trim corner 201 and the arc portion on the A-pillar flexible seal 1021 form a static interference seal.
[0036] In this embodiment, the corners of the A-pillar exterior panel 101, the side bright trim corners 202, and the interference corners of the top strip bright trim corners 201 all have bevels, and when the interference corners are inserted into the insertion gap, the bevels of the corners of the A-pillar exterior panel 101 and the bevels of the side bright trim corners 202 can fit together. The bevels of the corners of the A-pillar exterior panel 101 and the bevels of the side bright trim corners 202 can assist in the positioning of the side bright strip 2 and the A-pillar exterior panel assembly 1 during assembly, so that the side bright trim corners 202 are always inserted along the bevel direction of the A-pillar exterior panel 101. In addition, the coordination of the bevels of the two makes the connection between the A-pillar exterior panel assembly 1 and the side bright strip 2 have a better appearance quality, improving the design sense and smoothness of the vehicle interior. There is a fixed connection point between the front section of the A-pillar exterior trim panel 101 and the A-pillar exterior trim panel bracket 102. The A-pillar exterior trim panel 101 and the A-pillar exterior trim panel bracket 102 before the fixed connection point are in a mutually abutted connection relationship, and the A-pillar exterior trim panel 101 and the A-pillar exterior trim panel bracket 102 after the fixed connection point are in a fixed connection relationship. The interference corner of the top strip bright trim corner 201 is designed with a bevel structure, and the inclination angle of the bevel is basically consistent with the inclination angle of the bevel of the side panel bright trim corner 202, and the size of the inclination angle can be designed and selected according to actual usage requirements. Therefore, when the front end of the interference corner of the top strip bright trim corner 201 abuts against the above-mentioned fixed connection point, the position of the side panel bright strip 2 in the vertical direction can also be adjusted up and down along the bevel direction of the interference corner, so as to ensure the appearance quality of the connection between the side panel bright strip 2 and the A-pillar exterior trim assembly 1. For example, the angle between the hypotenuse of the corner of the A-pillar exterior panel 101 and the adjacent side located above is an acute angle, and the angle between the hypotenuse and the adjacent side located below is an obtuse angle, so as to form a hypotenuse structure inclined from the upper right to the lower left. Correspondingly, the angle between the hypotenuse of the corner of the side bright trim strip 202 and the adjacent side located above is an obtuse angle, and the angle between the hypotenuse and the adjacent side located below is an acute angle, so as to form a hypotenuse structure inclined from the lower left to the upper right. The hypotenuse of the corner of the A-pillar exterior panel 101 can also be an obtuse angle between the hypotenuse and the adjacent side located above. The angle between the angle of the corner of the A-pillar exterior panel 101 and the adjacent edges is an acute angle, so that a beveled edge structure is formed that is inclined from the lower right to the upper left. Correspondingly, the angle between the beveled edge of the side bright trim strip corner 202 and the adjacent edges above is an acute angle, and the angle between the beveled edge of the side bright trim strip corner 202 and the adjacent edges below is an obtuse angle, so that a beveled edge structure is formed that is inclined from the upper left to the lower right. Further, the beveled edge of the corner of the A-pillar exterior panel 101 can also be a right angle with each adjacent edge. Correspondingly, the angle between the beveled edge of the side bright trim strip corner 202 and each adjacent edge is a right angle. The beveled edge structure of the corner of the A-pillar exterior panel 101 and the beveled edge structure of the side bright trim strip corner 202 can be designed and selected according to actual use requirements. In the above description, "up" refers to the direction close to the side of the car, "down" refers to the direction away from the side of the car, "left" refers to the direction close to the A-pillar exterior panel 101, and "right" refers to the direction away from the A-pillar exterior panel 101.
[0037] See also Figure 4 and Figure 5 The frameless door sealing structure in this embodiment also includes a side panel top strip 3 that is clamped with the A-pillar exterior panel assembly 1 and the side panel bright strip 2. The side panel top strip 3 includes a top strip body 301, a first top strip lip 302, and a third top strip lip 304. A first top strip bayonet 305 is formed between the first top strip lip 302 and the top strip body 301, and a second top strip bayonet 306 is formed between the third top strip lip 304 and the top strip body 301. The side panel top strip 3 is clamped with the A-pillar exterior panel assembly 1 and the side panel bright strip 2 through the top strip lips and the top strip bayonet, which can fill the gap between the A-pillar exterior panel assembly 1 and the side panel bright strip 2 after they are matched, improve the appearance quality of the area, and ensure the close connection between the window glass 8 and the roof, thereby improving the sealing performance of the door.
[0038] In this embodiment, see Figure 5 The side panel top strip 3 also includes a second top strip lip 303. A top strip bayonet 103 is formed between the A-pillar exterior panel 101 and the A-pillar exterior panel bracket 102. The side panel top strip 3 is clamped into the top strip bayonet 103 through the second top strip bayonet 306. The top strip body 301 and the third top strip lip 304 are in interference connection with the A-pillar exterior panel 101. The second top strip lip 303 is in interference connection with the A-pillar exterior panel bracket 102. A plurality of side panel mounting holes are arranged at intervals on the A-pillar exterior panel bracket 102 in the top strip bayonet 103. Preferably, 8 mounting holes are arranged. The A-pillar exterior panel bracket 102 and the side panel can be fastened and fixed by using closed-hole embedded plastic nuts and cross-recessed round-head self-tapping screws. After the fixing is completed, the side panel top strip 3 is clamped into the top strip bayonet 103, which ensures the appearance quality of the top strip bayonet 103 and improves the sealing performance.
[0039] In this embodiment, reference Figure 4 The side bright strip 2 includes a first edge 205 and a second edge 206. The first edge 205 and the second edge 206 are integrally formed. A first lip 2051 is formed at the end of the first edge 205, and a second lip 2061 is formed at the end of the second edge 206. The first edge 205 and the second edge 206 intersect to form a first bayonet 208 and a second bayonet 209. The side bright strip 2 is generally in the shape of a long strip and is arranged above the edge of the window frame. A plurality of mounting holes 210 are provided on the first edge 205. Preferably, 8 mounting holes 210 are provided. The side bright strip 2 can be fixedly connected to the side outer panel 4 of the roof by the cooperation of closed-hole embedded plastic nuts and cross-recessed round head self-tapping screws. The second edge 206 is formed into an inwardly buckled arc structure, and the outer side of the second edge 206 is displayed inside the vehicle. The inwardly buckled arc bright strip has good appearance quality inside the vehicle.
[0040] In this embodiment, a support 207 is provided on the first bayonet 208 to connect with the top seal 203, and a side panel top strip 3 is clamped in the second bayonet 209. The support 207 can be an adhesive strip, and the top seal 203 is adhered to the first bayonet 208 by the viscosity of the adhesive strip. The top seal 203 is made of elastic material and can be triangular in cross section. When the side panel bright strip 2 is fixedly connected to the side panel outer panel 4 of the roof, the top seal 203 is deformed to both sides under the pressure of the side panel outer panel 4, so that the fitting surface of the top seal 203 and the side panel outer panel 4 is larger, and the sealing performance is effectively improved. In a preferred case, a glass fiber 2031 is provided in the top seal 203, and the glass fiber 2031 makes the top seal 203 have higher wear resistance, sound insulation and heat resistance, effectively protects the roof from ultraviolet rays and rain, and can effectively reduce noise and vibration inside the car. In the snap-fitting of the side panel bright strip 2 and the side panel top strip 3, the first top strip snap-fitting opening 305 is suitable for snap-fitting with the first lip 2051, the second top strip snap-fitting opening 306 is suitable for snap-fitting with the second lip 2061, and the second top strip lip 303 abuts against the inner side of the first panel edge 205. The side panel top strip 3 is snap-fitted into the second snap-fitting opening 209, which ensures the appearance quality of the second snap-fitting opening 209 and improves the sealing performance. When the window glass 8 moves from bottom to top to the side panel top strip 3, the side panel top strip 3 is squeezed, so that the side panel top strip 3 is deformed to both sides and abuts against both sides of the window glass 8, thereby achieving better window sealing.
[0041] In this embodiment, see Figure 3 , a bent portion 10211 extends from the end of the A-pillar flexible seal 1021, a waterproof foam 204 is provided on the upper surface of the first surround 205, and when the top strip bright trim corner 201 is inserted between the A-pillar exterior panel 101 and the A-pillar exterior panel bracket 102, the bent portion 12011 and the waterproof foam 204 are interfered with and connected, and at this time, the lower bottom surface of the bent portion 10211 is flush with the upper surface of the first surround 205 on the horizontal plane. The interference connection between the bent portion 12011 and the waterproof foam 204 further improves the stability of the connection between the A-pillar exterior panel assembly 1 and the side surround bright strip 2. Just above the mounting hole 210 on the first surround 205, a through hole is correspondingly opened in the waterproof foam 204, and the size of the through hole is larger than the mounting hole 210. It can be seen that the mounting hole 210 is used to cooperate with the screw 7, and the through hole on the waterproof foam 204 is used to cooperate with the nut 6.
[0042] See also Figure 3 and Figure 7In this embodiment, a sealing foam 5 is provided on the lower end surface of the bent portion 10211 and in the gap between the A-pillar flexible seal 1021 and the first surround 205. The sealing foam 5 is used to fill the connection gap between the A-pillar exterior panel assembly 1 and the side panel bright strip 2, and can prevent the A-pillar exterior panel bracket 102 from having a rigid contact with the first surround 205 of the side panel bright strip 2, and can assist the side panel top strip 3 to further enhance the sealing between the side panel bright strip 2 and the A-pillar exterior panel assembly 1, thereby reducing wind noise.
[0043] The utility model also provides a vehicle, including the above-mentioned frameless door sealing structure, in the process of assembling the A-pillar exterior panel assembly 1, the side panel bright strip 2 and the side panel top strip 3 of the vehicle, firstly, the A-pillar exterior panel assembly is fixed to the side panel by the matching connection of the nut 6 and the screw 7, and a sealing foam 5 is arranged on the side of the A-pillar exterior panel bracket 102 connected to the side panel outer panel 4 of the roof, so that the top surface of the A-pillar exterior panel bracket 102 is fixedly connected to the side panel outer panel 4 of the roof through the sealing foam 5, avoiding the rigid contact between the A-pillar exterior panel bracket 102 and the side panel outer panel 4, and can improve the sealing performance of this part. Furthermore, the A-pillar flexible seal 1021 can also fit tightly with the lower bottom surface of the side panel outer panel 4, adding a sealing defense line.
