Detailed implementation manners

[0023] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for explaining the present invention rather than limiting the protection scope of the present invention.

[0024] It should be noted that the drawings provided in the following embodiments only schematically illustrate the basic concept of the present invention. Therefore, only the components related to the present invention are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0025] As Figure 1 shown, the back door assembly according to an embodiment of the present invention is used for a vehicle. The back door assembly includes an outer panel 4 of the back door and a rear windshield 1. The rear windshield 1 is slidably disposed inside the outer panel 4 of the back door. A sliding space is defined between the outer panel 4 of the back door and the rear windshield 1. A sealing member 3 is disposed in the sliding space. The sealing member 3 is fixed on the outer panel 4 of the back door and is in interference fit with the rear windshield 1. The upper edge of the through - type taillight 2 is fixedly disposed on the outer side of the outer panel 4 of the back door and extends into the sliding space and is located above the sealing member 3.

[0026] In detail, the tailgate outer panel 4 is located between the through-taillight 2 and the rear windshield 1. Since the rear windshield 1 can be slidably arranged on the inner side of the tailgate outer panel 4, a sliding space is defined between the tailgate outer panel 4 and the rear windshield 1. The sliding space can enable the tailgate outer panel 4 to avoid the rear windshield 1 to prevent interference with the movement of the rear windshield 1. On the other hand, a seal 3 is provided in the sliding space. The interference fit between the seal 3 and the rear windshield 1 can achieve a waterproof and dustproof effect. The upper edge of the through-taillight 2 extends into the sliding space and is located above the seal 3. When the tailgate assembly is installed in the vehicle, the upper edge of the through-taillight 2 extends into the sliding space and is located above the seal 3. Therefore, the through-taillight 2 is used to shield the seal 3, preventing the seal 3 from aging and failure due to direct sunlight, thereby effectively ensuring the safety of the seal 3. When the tailgate assembly is used in a vehicle, the waterproof and dustproof effect of the vehicle can be improved.

[0027] It should be noted that the “inside” and “outside” mentioned in the above embodiments refer to the side close to the vehicle compartment as the inside and the side away from the vehicle compartment as the outside when the tailgate assembly is applied to the vehicle. Secondly, the through taillight 2 includes a lamp housing 22 and a photometric mirror 21. The upper edge of the lamp housing 22 may extend into the sliding space and be located above the seal 3, or the upper edge of the photometric mirror 21 may extend into the sliding space and be located above the seal 3, or the upper edge of the lamp housing 22 and the photometric mirror 21 may both extend into the sliding space, and the upper edge of at least one of the lamp housing 22 and the photometric mirror 21 may be located above the seal 3. In addition, it is understandable that there is a gap between the upper edge of the through taillight 2 and the rear windshield 1, so that the through taillight 2 avoids the rear windshield 1 to prevent interference with the rear windshield 1.

[0028] The width W of the sliding space satisfies: 10mm≤W≤20mm. This can prevent the rear windshield 1 from interfering with other components during the up and down sliding process, and also prevent the possibility of poor sealing of the entire vehicle due to the excessive width of the sliding space. Among them, W can be 10mm, 12mm, 14mm, 16mm, 18mm and 20mm, etc.

[0029] Generally, the sealing member 3 includes but is not limited to rubber-asbestos board, aerogel felt-polyurethane and rubber, etc. Generally, the sealing member 3 is mostly made of rubber material, which is not limited in the present application.

[0030] According to the tailgate assembly of the embodiment of the present invention, the seal 3 is invisible in appearance, which can effectively prevent aging caused by direct sunlight and shorten the service life, ensure the safety of the seal 3, and enhance the waterproof and dustproof effect of the vehicle.

[0031] like Figure 1As shown, in some embodiments, a back door bracket 5 is provided on the inner side surface of the back door outer panel 4. The back door outer panel 4 and the back door bracket 5 jointly define a communicating mounting hole. The back door assembly further includes: a fixing bracket 33, which is passed through the mounting hole to be clamped with both the back door outer panel 4 and the back door bracket 5 at the same time. One end of the fixing bracket 33 close to the rear windshield 1 is fixedly connected with a seal 3. That is to say, the seal 3 is fixedly connected with the fixing bracket 33, and the seal 3 is detachably fixed to the back door outer panel 4 through the fixing bracket 33. Since the through-tail lamp 2 and the fixing bracket 33 need to be fixedly installed on the back door outer panel 4, and considering the weight of the whole vehicle, the thickness of the back door outer panel 4 is moderate. In order to increase the structural strength of the back door outer panel 4 and prevent deformation due to insufficient structural strength when installing the through-tail lamp 2 and the fixing bracket 33, a back door bracket 5 is provided on the inner side surface of the back door outer panel 4 to increase the structural strength of the back door outer panel 4.

[0032] During processing, the seal 3 and the limiting portion 32 of the fixing bracket 33 can be injection-molded together, thereby increasing the structural strength of the connection between the fixing bracket 33 and the seal 3 and simplifying the processing steps at the same time.

[0033] In a specific embodiment, the portion of the fixing bracket 33 passing through the back door outer panel 4 and the back door bracket 5 is configured as a cylinder. In this way, after the fixing bracket 33 is inserted into the mounting hole, it is convenient to flatten the portion of the fixing bracket 33 extending beyond the back door outer panel 4 on the back door outer panel 4, thereby preventing the fixing bracket 33 from slipping out of the mounting hole and realizing the fixation of the fixing bracket 33. Then, the through-tail lamp 2 is assembled on the back door outer panel 4, so that the connection position between the fixing bracket 33 and the back door outer panel 4 is not exposed from the appearance.

[0034] Among them, the back door bracket 5 can be made of plastic, metal material, and other materials that can meet the structural strength requirements. Usually, the back door bracket 5 is made of metal material, so that it has excellent performance of preventing wind, sun and aging.

[0035] The width W1 between any position on the surface of the back door bracket 5 facing the rear windshield 1 and the rear windshield 1 satisfies: 10mm ≤ W1 ≤ 18mm. In this way, it can not only prevent the rear windshield 1 from interfering with the back door bracket 5 during the up and down sliding process, but also prevent the possibility of poor sealing of the whole vehicle due to too large a width. Among them, W1 can be 10mm, 12mm, 14mm, 16mm, 18mm, etc.

[0036] Such as Figure 1As shown, in some embodiments, the through-tail lamp 2 includes a lamp housing 22 and a light distribution lens 21. The lamp housing 22 is fixed to the outer side of the back door outer panel 4, and the light distribution lens 21 is mounted on the lamp housing 22. The upper edge of the light distribution lens 21 extends into the sliding space and is located above the seal 3. Since the lamp housing 22 also has a certain weight, only setting the upper edge of the light distribution lens 21 to extend into the sliding space and be located above the seal 3 can, while satisfying the possibility that at least part of the seal 3 is obscured from the appearance, reduce the overall structural weight of the through-tail lamp 2, thereby reducing the requirement for the structural strength of the back door outer panel 4, thus reducing the overall weight of the back door bracket 5 and the back door outer panel 4, enabling the vehicle to be lightweight and reducing fuel consumption.

[0037] Wherein, the lamp housing 22 and the light distribution lens 21 can be detachably connected, such as snap connection, or can also be fixedly connected, such as welding, which is not limited in this application.

[0038] In addition, the minimum distance L between the upper edge of the light distribution lens 21 and the rear windshield satisfies: 3mm ≤ L ≤ 6mm. Wherein, L can be 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, and 6mm.

[0039] As Figure 1 As shown, in some embodiments, the lamp housing 22 includes a lamp housing body 220 and a plurality of fixing parts 224 provided on the lamp housing body 220. The fixing parts 224 are used for welding connection with the light distribution lens 21. The lamp housing body 220 is bent to form an avoidance space, and the back door outer panel 4 is opposite to the avoidance space. It can be understood that the fixing parts 224 not only serve as the installation and fixing points for the light distribution lens 21, but also can position the assembly of the light distribution lens 21. By providing a plurality of fixing parts 224 on the lamp housing body 220, the light distribution lens 21 can be installed and limited at multiple positions, increasing the connection stability between the light distribution lens 21 and the lamp housing 22 during driving. Since there are various extreme road conditions during vehicle driving, which may cause bumps between various components of the whole vehicle, therefore, setting the avoidance space can prevent collision between the lamp housing 22 and the back door outer panel 4 during vehicle driving.

[0040] As Figure 1As shown, in some embodiments, the lamp housing body 220 is bent to form a first body 221, a connecting portion 223, and a second body 222. The connecting portion 223 connects the first body 221 and the second body 222 respectively. The first body 221 and the connecting portion 223 jointly define an avoidance space. The first body 221 faces the rear door outer panel 4, and the second body 222 is located above the rear door outer panel 4. At least one fixing portion 224 is provided on the second body 222. In this way, the light distribution lens 21 can be more conveniently fixed on the second body 222, simplifying the setting of the light distribution lens 21 and the lamp housing 22. When the rear door assembly is assembled in the vehicle, the distance between the upper edge of the light distribution lens 21 and the seal 3 in the vertical direction can be increased, preventing the rear windshield 1 from driving the seal 3 to deform and interfere with the light distribution lens 21 when sliding.

[0041] Among them, the distance H between the first body 221 and the rear door outer panel 4 satisfies: 2mm ≤ H ≤ 4mm. If H is too small, the safety distance between the lamp housing 22 and the rear door outer panel 4 is smaller, and it is easy for various components to collide when jolting during various extreme driving processes of the vehicle. If H is too large, the gap between the lamp housing 22 and the rear door outer panel 4 will be too large, and it is easy to accumulate dust and debris. Among them, H can be 2mm, 2.5mm, 3mm, 3.5mm, 4mm, etc.

[0042] As Figure 1 shown, in some embodiments, the seal 3 includes a rubber strip body, and at least one first stop portion 31 is provided on the rubber strip body. The first stop portion 31 inclines upward in the direction gradually away from the rubber strip body, and the end of the first stop portion 31 away from the rubber strip body abuts against the rear windshield 1. Setting the first stop portion 31 to incline upward in the direction gradually away from the rubber strip body can, on the one hand, reduce the friction between the rear windshield 1 and the first stop portion 31 when the rear windshield 1 slides upward, and on the other hand, prevent the rear windshield 1 from driving the first stop portion 31 to move and incline when sliding downward. In addition, the first stop portion 31 can play a role in collecting water and dust, preventing waste water and dust from penetrating into the vehicle interior.

[0043] It can be understood that "at least one first stop portion 31 is provided on the rubber strip body" means that in some specific embodiments, one first stop portion 31 is provided on the rubber strip body, and in some specific embodiments, multiple first stop portions 31 are provided on the rubber strip body. For example, two, three, four, five, six, and more.

[0044] In some embodiments, there are multiple first stop portions 31, and the multiple first stop portions 31 are spaced apart along the length direction of the rubber strip body. In this way, the effect of multiple anti-seepage and dust collection can be achieved, greatly improving the sealing reliability of the seal 3. The length direction of the seal 3 is along as Figure 1extends in the front - rear direction perpendicular to the paper plane as shown, and the length direction of the first stop portion 31 extends along as Figure 1 shown in the front - rear direction perpendicular to the paper plane.

[0045] For example, as Figure 1 shown, the number of the first stop portions 31 is two, and the ef section of the rear windshield 1 is the interference area with the seal 3 to prevent water ingress.

[0046] As Figure 1 shown, in some embodiments, two - color areas ab are respectively provided in the areas of the light distribution lens 21 near both ends of the lamp housing 22. The two - color area ab includes a stacked primary part and a secondary part, and the primary part and the secondary part have different colors. The light distribution lens 21 is usually made of PC material. The PC material can be injection - molded, extruded, molded, blow - molded, thermo - formed, printed, bonded, coated, and machined, etc. The mainstream is injection molding. In order to ensure a high yield rate of the light distribution lens 21 and prevent light leakage, the light distribution lens 21 is provided with the two - color area ab. At the same time, since the light transmittance of the two - color area ab is relatively low, it can absorb light and heat, further prevent light from directly irradiating the seal 3, prevent the seal 3 from aging, and extend the service life of the seal 3. In addition, the two - color area ab can also shield the welding joint between the light distribution lens 21 and the lamp housing 22 and the seal 3 from the appearance, improving the overall aesthetics.

[0047] In some embodiments, a second stop portion 34 is further provided at the upper end of the rubber strip body. The second stop portion 34 is inclined in the direction of gradually approaching the first stop portion 31 in the direction of gradually moving away from the rubber strip body. The first stop portion 31 and the second stop portion 34 jointly define a receiving groove with an open top. In this way, the receiving groove can better collect waste water such as cleaning liquid and rainwater, and with the driving of the vehicle, the waste water is emptied by evaporation, greatly improving the waterproof and dust - proof effect of the vehicle. In addition, at least part of the second stop portion 34 is spaced from the rear door bracket 5, which can simplify the assembly difficulty of the seal 3 with the rear door bracket 5 and the rear door outer panel 4.

[0048] In some embodiments, the included angle ɑ between the first stop portion 31 and the rear door bracket 5 satisfies: 2°≤ɑ≤10°. If ɑ is too large, the top opening of the receiving groove will decrease, making it difficult for the waste water to completely flow into the receiving groove and possibly remaining between the first stop portion 31 and the rear door bracket 5. If ɑ is too small, the assembly difficulty of the seal 3 with the rear door bracket 5 and the rear door outer panel 4 will increase. Therefore, it is necessary to set an appropriate size of ɑ. Among them, ɑ can be 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, and 10°, etc.

[0049] In some embodiments, the edge of the first stop portion 31 bends and extends towards the direction close to the first stop portion 31 to form a hook. In this way, during the driving of the vehicle, with the bumps of the vehicle, the hook can prevent wastewater and the like from sloshing out of the accommodating groove, further improving the sealing and waterproof performance of the vehicle.

[0050] Among them, the first stop portion 31, the second stop portion 34 and the rubber strip body are integrally formed.

[0051] The vehicle according to the embodiment of the present invention includes the above-mentioned back door assembly.

[0052] For the vehicle according to the embodiment of the present invention, the seal 3 is not visible externally, which can effectively prevent the shortening of the service life caused by aging due to direct sunlight, ensure the use safety of the seal 3, and improve the waterproof and dustproof effect of the vehicle.

[0053] It can be understood that the vehicle in the embodiment of the present application can be all vehicles with the ability to move, including vehicles with autonomous driving or intelligent driving, such as manned vehicles (sedans, buses, coaches, minibuses, etc.), cargo vehicles (ordinary trucks, van trucks, special vehicles (logistics delivery vehicles, patrol vehicles)), vehicles with entertainment functions, rescue vehicles (such as fire trucks, ambulances), etc.
