Description

Technical Field

[0001] The present application relates to the technical field of vehicle tailgate sealing, and in particular to a tailgate assembly and a vehicle. Background Art

[0002] In the modern automotive industry, with the diversification of vehicle designs and consumers' increasing demands for vehicle performance, split tailgate designs have gradually become a popular trend. Split tailgates typically consist of an upper, flip-up glass panel and a lower, side-opening tailgate. This not only provides more flexible opening and closing options for the rear of the vehicle, but also enhances overall aesthetics and practicality. However, while this design offers convenience, it also introduces some technical challenges, the most notable of which is sealing performance. Currently, split tailgate glass is typically equipped with a sealing strip and a sealing strip corner. When the tailgate is closed, the sealing strip corner is directly squeezed to achieve a seal at the junction between the tailgate and the glass. However, due to manufacturing and assembly tolerances of the tailgate sheet metal and glass, the sealing strip corners on both sides of the tailgate and glass are difficult to fully align, resulting in water leakage in rainy days or when washing the car. This affects the reliability and lifespan of the vehicle's internal components and reduces driving and riding comfort. Utility Model Content

[0003] This application aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of this application is to provide a tailgate assembly that, by means of a second sealing member cooperating with a joint on the door glass, can reduce the impact of component manufacturing and assembly tolerances on the seal, optimize the sealing effect between the door body and the door glass, effectively block liquids, dust, and noise, thereby maintaining a clean interior, improving the reliability and lifespan of vehicle components, and enhancing driving comfort.

[0046] Reference below Figure 1-Figure 5 A tailgate assembly 1000 and a vehicle according to an embodiment of the present application are described.

[0047] like Figure 1 and Figure 2 As shown, according to the rear door assembly 1000 of the first embodiment of the present application, the rear door assembly 1000 includes: a door body 1, a door glass 2 and a second sealing member 4.

[0048] Among them, the door body 1 can be rotatably connected to one side of the vehicle body in the width direction to switch between a first open position and a first closed position; the door glass 2 is arranged on the door body 1, and can be selectively rotated around the width direction of the vehicle body to switch between a second open position and a second closed position, and the door glass 2 is provided with a first seal, and the first seal has a connecting angle 31 arranged on both sides of the door glass 2 in the width direction; the second seal 4 is arranged on the door body 1, and in the second closed position, the second seal 4 is pushed against the connecting angle 31.

[0049] Specifically, the door body 1 can be connected to one side of the vehicle body in the width direction by a rotatable connecting mechanism (such as a hinge or a hinge), and the door body 1 rotates relative to the vehicle body around the height direction of the vehicle body to switch freely between a first open position and a first closed position. In the first closed position, the door body 1 fits against the vehicle body to close the rear opening of the vehicle. In the first open position, the door body 1 is fully or partially opened to facilitate loading and unloading of goods or entry and exit of passengers; the door glass 2 can be rotated around the width direction of the vehicle body, which can be understood as the door glass 2 can be lifted up and flipped down to achieve switching between the second open position and the second closed position, and the rotation of the door glass 2 is an independent movement relative to the door body 1. Without changing the overall position of the door body 1, the door glass 2 can be individually opened and closed. It can open and close itself independently. In this way, when in some narrow environments, the user can only open the door glass 2 for ventilation or to put items as needed, without having to fully open the entire door body 1; the first seal can be set at the bottom end of the door glass 2 (that is, the end of the door glass 2 away from the rotating connection with the door body 1), and the first seal can be used to achieve the sealing function between the door glass 2 and the door body 1 when the door glass 2 is in the second closed position. The first seal has a joint corner 31 arranged on both sides of the door glass 2 in the width direction, and the door body 1 is provided with a second seal 4. When the door glass 2 is in the second closed position, the second seal 4 can contact and push against the joint corners 31 on both sides of the door glass 2 to ensure a tight fit between the door glass 2 and the door body 1.

[0050] It should be pointed out that the above-mentioned door glass 2 can be indirectly connected to the vehicle body by being set on the door body 1, and the door glass 2 can also be directly set on the vehicle body and directly connected to the vehicle body. This application does not limit the direct or indirect connection between the door glass 2 and the vehicle body.

[0051] According to the tailgate assembly 1000 of the present application, the second sealing member 4 on the door body 1 can be pushed against the corner 31 on the door glass 2 to achieve a good seal at the junction of the door body 1 and the door glass 2. Compared with the related art in which the tailgate directly squeezes the sealing strip corner for sealing when closing, there is a problem that the sealing strip corner is difficult to fully fit due to the manufacturing and assembly tolerances of the tailgate sheet metal and glass. The door body 1 of the present application is provided with a second sealing member 4, which fills a part of the gap between the door body 1 and the door glass 2, thereby reducing the size of the corner 31. The second sealing member 4 and the corner 31 are pushed against each other for sealing, which solves the problem of poor adaptability of the sealing member and the gap caused by the manufacturing and assembly tolerances of the members, thereby enhancing the sealing effect, effectively preventing the intrusion of external liquids, dust and noise, keeping the interior of the vehicle clean, improving the working reliability and life of the members in the vehicle, and improving driving comfort.

[0052] According to some embodiments of the present application, the corners 31 located on both sides of the door glass 2 in the width direction are respectively constructed as first side corners 31a and second side corners 31b, and the second seal 4 is constructed as first side second seals 4a and second side second seals 4b respectively arranged on both sides of the door body 1 in the width direction, and the first side second seal 4a is suitable for cooperating with the first side corner 31a, and the second side second seal 4b is suitable for cooperating with the second side corner 31b. Among them, the first side second seal 4a can be arranged on the side where the door body 1 is rotationally connected to the vehicle body, and the second side second seal 4b is arranged on the side where the door body 1 and the vehicle body can be selectively locked. The shapes and sizes of the first side second seal 4a and the second side second seal 4b can be different to improve the adaptability of the first side second seal 4a and the second side second seal 4b to the different functional side structures of the door body 1 respectively. Furthermore, in some specific embodiments, the extension direction of the first side second seal 4a is consistent with the length direction of the vehicle body to ensure good adaptability of the first side second seal 4a and the side where the door body 1 is rotationally connected to the vehicle body, and the extension direction of the second side second seal 4b is consistent with the width direction of the vehicle body to ensure good adaptability of the second side second seal 4b to the side where the door body 1 and the vehicle body can be selectively locked. In this way, the stability and sealing performance of the door body 1 and the door glass 2 in the closed position can be improved.

[0053] Furthermore, in some specific embodiments of the present application, the first sealing member includes a sealing strip 32, which is disposed at the bottom of the door glass 2 and extends along the width of the door glass 2. Joints 31 are disposed at both ends of the sealing strip 32 in the extending direction. The sealing strip 32 and the joints 31 together cover the entire width of the bottom of the door glass 2. Thus, in the second closed position, the sealing strip 32, the joints 31, and the second sealing member 4 provide all-round sealing protection for the door glass 2 and the door body 1, thereby preventing the intrusion of external moisture, dust, or noise.

[0054] like Figures 1-4 As shown, according to some embodiments of the present application, the door body 1 has an inner panel 11 , and the second sealing member 4 is provided on the inner panel 11 .

[0055] Specifically, the inner panel 11 is one of the main supporting structures of the door body 1, which can provide the necessary strength and rigidity for the entire door body 1 to ensure the normal operation and safety of the entire door body 1. Among them, defined by the vehicle height space, the inner panel 11 can be located below the door glass 2, and a second seal 4 is provided on the top of the inner panel 11, and a joint angle 31 is provided at the bottom end of the door glass 2. When the door glass 2 moves to the second closed position, the joint angle 31 at the bottom end of the door glass 2 can smoothly contact and fit tightly with the second seal 4 on the top of the inner panel 11, thereby achieving good sealing between the door glass 2 and the door body 1, and is conducive to improving the position stability of the door glass 2.

[0056] like Figure 3-Figure 5 As shown, according to some embodiments of the present application, the inner panel 11 includes a main body 111, and the top of the main body 111 has a first section 112 and a second section 113 connected in sequence, and the end of the second section 113 away from the first section 112 is suitable for being connected to the first seal in the second closed position, and the first section 112 and the second section 113 define an installation cavity 11a on one side facing each other, and the second seal 4 is arranged in the installation cavity 11a.

[0057] Specifically, the top of the body 111 is connected in sequence with a first section 112 and a second section 113. It can be understood that the first section 112 is located between the body 111 and the second section 113, and the extension directions of the first section 112 and the second section 113 form a certain angle. For example, the first section 112 can be away from the body 111 in the height direction and extend in a direction away from the vehicle interior cockpit, while the second section 113 can be away from the body 111 in the height direction and extend in a direction close to the vehicle interior cockpit. The first section 112 and the second section 113 define a mounting cavity 11a on one side facing each other. The mounting cavity 11a provides space for the installation of the second seal 4 and provides good protection for the second seal 4. Placing the second seal 4 in the mounting cavity 11a is conducive to improving the installation stability and reliability of the second seal 4. In addition, the mounting cavity 11a can also help to reduce stress concentration caused by vibration or temperature changes on the second seal 4 to a certain extent, thereby extending its service life.

[0058] like Figure 5 As shown, according to some embodiments of the present application, the top of the second sealing member 4 has a first surface 41 a , and the side of the corner 31 facing away from the door glass 2 has a second surface 311 , and the second surface 311 is suitable for abutting against the first surface 41 a .

[0059] Specifically, the second seal 4 and the corner 31 have a second surface 311 and a first surface 41a, respectively. Both the second surface 311 and the first surface 41a can be curved, flat, or a combination of flat and curved surfaces. In the second closed position, the first surface 41a of the second seal 4 can abut against the second surface 311 of the corner 31 to form a tight sealing structure, effectively preventing external liquids, dust and other impurities from entering the vehicle, and reducing the transmission of noise, thereby improving the safety, comfort and quietness of the vehicle. The use of a surface-to-surface contact between the first surface 41a and the second surface 311 can increase the contact area between the second seal 4 and the corner 31, and enhance the connection strength and stability between the two. This helps to reduce loosening or deformation caused by vibration or external force, thereby further improving the sealing reliability and sealing performance between the door body 1 and the door glass 2.

[0060] It should be noted that the first surface 41a of the second sealing member 4 can be designed to conform to the shape of the corner 31 to ensure that the first surface 41a fits well with the second surface 311 on the corner 31 to ensure a good sealing effect.

[0061] like Figure 3-Figure 5 As shown, according to some embodiments of the present application, the second sealing member 4 includes: a base 41 and an adhesive layer 42 coated on at least one surface of the base 41 .

[0062] The base 41 is disposed on the inner panel 11 , a surface of the base 41 facing the inner panel 11 is connected to the inner panel 11 , and a surface of the base 41 away from the inner panel 11 is not provided with the adhesive layer 42 .

[0063] Specifically, the second seal 4 consists of two parts: a base 41 and an adhesive layer 42. The base 41 is the main supporting part of the second seal 4, which can provide the necessary strength and rigidity so that the second seal 4 can maintain a stable shape and performance during long-term use. At the same time, the base 41 is connected to the inner panel 11 to ensure that the second seal 4 as a whole can be firmly fixed on the door body 1 to ensure that the second seal 4 has good working reliability and stability; the adhesive layer 42 is coated on at least one surface of the base 41. The adhesive layer 42 can be made of a material with good sealing and adhesion properties, such as rubber, silicone, etc. The adhesive layer 42 can fill the tiny gap between the second seal 4 and other components (such as the inner panel 11) and provide sealing and adhesion effects, so that the second seal 4 can be tightly connected with components such as the inner panel 11 to ensure the sealing effect and installation stability.

[0064] It should be pointed out that the adhesive layer 42 is not provided on the surface of the side of the base 41 away from the inner panel 11. Defined by the height space of the vehicle body, the adhesive layer 42 is not provided on the top of the base 41. Since the corner 31 is usually made of rubber or other materials, if the adhesive layer 42 is provided on the surface of the side of the base 41 away from the inner panel 11, in the second closed position, the adhesive layer 42 is in contact with the corner 31. Since both are made of soft adhesive materials such as rubber, abnormal noise is easily generated by contact. Therefore, the present application sets an adhesive layer 42 to cover at least one surface of the base 41, and no adhesive layer 42 is provided on the surface of the side of the base 41 away from the inner panel 11. This can achieve good sealing effect while avoiding abnormal noise, optimize sound insulation and noise reduction performance, and enhance user experience.

[0065] Preferably, the adhesive layer 42 covers all side surfaces of the base 41 in the horizontal direction to ensure good sealing and adhesion between the second sealing member 4 and other components.

[0066] In addition, in some specific embodiments of the present application, the base 41 is constructed of plastic material to achieve good support, save costs and improve lightweight.

[0067] In other specific embodiments of the present application, the adhesive layer 42 is coated on the base 41 using a two-color injection molding process, so that the second sealing member 4 is composed of two different materials: the base 41 and the adhesive layer 42. There is a certain amount of interference between the adhesive layer 42 and the inner panel 11 to ensure a good sealing effect.

[0068] like Figure 5 As shown, according to some embodiments of the present application, the base 41 is snap-connected with the inner panel 11 .

[0069] Specifically, the connection method between the base 41 and the inner panel 11 can be constructed as a snap-on connection, for example, through a snap-on connection such as a protrusion and a groove or a snap-on connection and a slot. By setting the base 41 to be snap-on with the inner panel 11, on the one hand, the snap-on connection is stable, so that the base 41 can be firmly fixed on the inner panel 11, which can improve the connection reliability and stability between the base 41 and the inner panel 11; on the other hand, the snap-on connection is simple and quick during installation and disassembly, which can effectively improve production efficiency and convenience of maintenance and replacement.

[0070] like Figure 5 As shown, according to some embodiments of the present application, the base 41 includes: a middle portion 411 and a first side portion 412 .

[0071] Among them, the middle portion 411 is arranged in the first section 112 and is separated from the second section 113, and the middle portion 411 extends in the height direction of the vehicle body; the first side portion 412 is arranged at the top end of the middle portion 411 and extends close to the second section 113, and the end of the first side portion 412 away from the middle portion 411 is suitable for connection with the second section 113, and the side of the first side portion 412 facing away from the first section 112 has a first surface 41a.

[0072] Specifically, the middle portion 411 can be disposed in the first section 112 of the inner panel 11 and spaced apart from the second section 113 of the inner panel 11. The first side portion 412 is disposed at the top of the middle portion 411, that is, the first side portion 412 is disposed at the end of the middle portion 411 facing away from the first section 112 in the height direction. The first side portion 412 extends toward the second section 113, and the side of the first side portion 412 facing away from the first section 112 has a first surface 41a, thereby achieving a secure connection between the base 41 and the corner 31 and improving the overall stability of the sealing structure. The extension directions of the first side portion 412 and the middle portion 411 form an angle, and the middle portion 411 can provide good support for the first side portion 412, thereby enhancing the overall stability and rigidity of the base 41.

[0073] like Figure 5 As shown, according to some embodiments of the present application, the base 41 further includes: a second side portion 413 , which is disposed at the bottom end of the middle portion 411 and extends away from the first side portion 412 in a direction close to the second section 113 .

[0074] Specifically, the second side portion 413 can be disposed at the bottom end of the middle portion 411, while the first side portion 412 is disposed at the top end of the middle portion 411, so that the second side portion 413 and the first side portion 412 are opposite in the vehicle body height direction. Furthermore, the second side portion 413 extends away from the first side portion 412 in a direction close to the second section 113, so that the second side portion 413, the middle portion 411, and the first side portion 412 collectively form a doghouse structure. The doghouse structure can prevent plastic shrinkage marks on the base 41, thereby effectively improving the reliability and stability of the base 41. Furthermore, by connecting to the middle portion 411, the second side portion 413 can provide more support points for the installation of the base 41 on the inner panel 11, making the base 41 more stable in the face of the forces and moments generated when the door body 1 is opened and closed.

[0075] like Figure 5 As shown, according to some embodiments of the present application, a clamping claw 413 a is provided at one end of the second side portion 413 away from the middle portion 411 , and the first section 112 has a clamping groove, and the clamping claw 413 a is suitable for extending into the clamping groove.

[0076] Specifically, the engaging claw 413a can be provided at an end of the second side portion 413 away from the middle portion 411. The engaging claw 413a is adapted to engage with the engaging groove on the first section 112 of the inner panel 11. The engaging claw 413a extends into the engaging groove to securely engage the second side portion 413 with the first section 112. The provision of the engaging claw 413a and the engaging groove can, on the one hand, enhance the connection strength between the base 41 and the inner panel 11, further increasing the installation stability of the second seal 4, thereby improving the operating reliability and lifespan of the second seal 4. Furthermore, the provision of the engaging claw 413a and the engaging groove increases the number of connection points between the base 41 and the inner panel 11, thereby improving the stability of the adhesive layer 42 on the outside of the base 41 and optimizing the sealing performance of the second seal 4.
