Description

Technical Field

[0001] This invention relates to vehicle structure, specifically to a segmented tailgate structure, tailgate assembly process, and vehicle. Background Technology

[0002] Currently, plastic tailgates are used in some mid-to-high-end electric vehicles. To achieve longer driving ranges, lightweighting is a key research focus for electric vehicles, and replacing sheet metal tailgates with plastic tailgates is an effective solution. Due to limitations in sheet metal stamping processes, sheet metal tailgates cannot be formed with greater depth, smaller rounded corners, or complex structures. Plastic tailgates, using injection molding, can be formed with greater depth, smaller rounded corners, and complex structures, enriching the design of vehicle tailgates and bringing new styling highlights. Although current plastic tailgates have made some progress in weight reduction and styling variety, the current method of installing taillights and continuous taillights on plastic tailgates is the same as that of traditional sheet metal tailgates. Therefore, when installing continuous taillights on plastic tailgates, the matching gap between the plastic tailgate and the continuous taillight is still relatively large. Problems such as uneven matching gaps, uneven surface differences, and low assembly pass rates of continuous taillights remain unresolved. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide a segmented tailgate structure that reduces the requirements for injection molding equipment, reduces equipment investment, and simultaneously achieves lightweighting and improved appearance. Another purpose of this invention is to provide a tailgate assembly process that reduces material turnover, the number of tooling components, and the floor space required for assembly. A further purpose of this invention is to provide a vehicle including the aforementioned segmented tailgate structure.

[0004] The present invention discloses a segmented tailgate structure, including a tailgate outer panel assembly, which includes an upper tailgate outer panel, a middle tailgate outer panel, and a lower tailgate outer panel. The upper part of the middle tailgate outer panel is connected to the lower part of the upper tailgate outer panel, and the lower part of the middle tailgate outer panel is connected to the upper part of the lower tailgate outer panel. The middle tailgate outer panel integrates a taillight cover function.

[0005] Furthermore, the upper and lower sections of the tailgate outer panel are single-color injection molded parts made of non-transparent material, while the middle section of the tailgate outer panel is a double-layer, two-color injection molded part made of both transparent and non-transparent material.

[0006] Furthermore, the middle section of the tailgate outer panel includes a first opaque area, a translucent area, and a second opaque area. The upper part of the translucent area is connected to the lower part of the first opaque area, and the lower part of the translucent area is connected to the upper part of the second opaque area. There is a gap between the first opaque area and the second opaque area. The middle part of the translucent area corresponds to the position of the gap to realize the function of integrating the taillight cover.

[0007] Furthermore, the segmented tailgate structure also includes an inner tailgate panel and a taillight housing. The inner tailgate panel is located on the front side of the outer tailgate panel assembly, and the taillight housing is located between the middle section of the outer tailgate panel and the inner tailgate panel.

[0008] Furthermore, the segmented tailgate structure also includes a tailgate glass. The upper part of the outer tailgate panel has an inverted "U" shape. The left, upper, and right parts of the tailgate glass are all connected to the upper part of the outer tailgate panel. The lower part of the tailgate glass is connected to the inner tailgate panel. There is an accommodating space between the lower end of the tailgate glass and the inner tailgate panel. The upper end of the first non-transparent area extends into the accommodating space.

[0009] Furthermore, the first non-transparent area includes a first upwardly inclined portion, a first middle inclined portion, and a first downwardly inclined portion arranged sequentially from top to bottom. The first upwardly inclined portion slopes backward from top to bottom, the first middle inclined portion slopes forward from top to bottom, and the first downwardly inclined portion slopes backward from top to bottom. A first mounting portion extending forward is provided at the connection between the first middle inclined portion and the first downwardly inclined portion. The second non-transparent area includes a second upwardly inclined portion, a second middle inclined portion, and a second downwardly bent portion arranged sequentially from top to bottom. The second upwardly inclined portion slopes forward from top to bottom, and the second middle inclined portion slopes backward from top to bottom. A second mounting portion extending forward is provided at the connection between the second upwardly inclined portion and the second middle inclined portion. Both the first mounting portion and the second mounting portion are connected to the taillight housing by plastic welding or bonding.

[0010] Furthermore, the second lower bending portion includes a vertical portion arranged in the up-down direction and a horizontal portion arranged in the front-back direction. The vertical portion is connected to the second middle inclined portion, and the front end of the horizontal portion is connected to the lower section of the tailgate outer panel. The middle part of the horizontal portion is provided with a license plate light mounting hole. A license plate mounting structure is provided on the lower section of the tailgate outer panel, and the license plate mounting structure is located below the license plate light mounting hole.

[0011] Furthermore, the upper section of the outer tailgate panel is connected to the middle section of the outer tailgate panel, the upper section of the outer tailgate panel is connected to the inner tailgate panel, the middle section of the outer tailgate panel is connected to the inner tailgate panel, the tailgate glass is connected to the upper section of the outer tailgate panel, the tailgate glass is connected to the inner tailgate panel, and the lower section of the outer tailgate panel is connected to the inner tailgate panel by adhesive bonding; the middle section of the outer tailgate panel is connected to the lower section of the outer tailgate panel by snap-fitting and adhesive bonding.

[0012] The present invention discloses a tailgate assembly process for assembling a segmented tailgate structure, comprising the following steps:

[0013] S1. Assemble the middle section of the tailgate outer panel and the taillight housing to form a first assembly assembly;

[0014] S2. Assemble the first assembly assembly with the lower section of the tailgate outer panel to form the second assembly assembly;

[0015] S3. Assemble the second assembly assembly, the upper section of the outer panel, and the inner panel of the tailgate to form the third assembly assembly;

[0016] S4. Assemble the third assembly component and the tailgate glass.

[0017] The vehicle of the present invention is characterized by including a segmented tailgate structure.

[0018] The beneficial effects of this invention are:

[0019] (1) By dividing the tailgate outer panel assembly into three sections, the present invention simplifies the product structure. The upper, middle, and lower sections of the tailgate outer panel are processed separately, which facilitates injection molding and avoids sacrificing part of the structure to ensure injection molding demolding. The appearance structure and shape are more flexible after segmentation. The processes and materials of the upper, middle, and lower sections of the tailgate outer panel can also be different. The process of integrating the taillight cover function in the middle section of the tailgate outer panel is more complex, and the material also needs to be light-transmitting. The tailgate outer panel assembly only uses double-layer injection molding in the middle part. The entire tailgate outer panel assembly does not need to use a large area of ​​double-layer injection molding, which reduces the requirements of injection molding equipment, reduces equipment investment, reduces labor costs, reduces material usage, reduces product costs, and achieves lightweighting.

[0020] (2) The taillight cover function is integrated in the middle section of the tailgate outer panel of the present invention. It does not require a separate taillight cover component, which reduces the weight of the tailgate and eliminates the assembly gap and surface difference between the taillight cover and the tailgate outer panel. The connection position between the taillight housing and the middle section of the tailgate outer panel can be set after the first non-transparent area and the second non-transparent area. The fit gap, surface difference and bonding structure between the taillight housing and the middle section of the tailgate outer panel are all hidden by the non-transparent area and are not visible from the outside. It effectively solves the problems of large matching gap, uneven gap, uneven surface difference and low matching qualification rate of the through taillight installation in traditional models and the problem of long assembly time, which can further improve the appearance aesthetics.

[0021] (3) The present invention is not easy to accumulate water and has strong waterproof performance.

[0022] (4) The present invention integrates license plate light mounting holes on the lower section of the tailgate outer panel, allowing the license plate light to be installed at this location. The license plate light provides illumination to the license plate mounting structure. The through direction of the license plate light mounting holes is along the vertical direction. After dividing the tailgate outer panel into three sections, the structure of the lower section of the tailgate outer panel is simple, and the structure of the license plate light mounting holes does not affect the injection molding and demolding of the lower section of the tailgate outer panel. Furthermore, the horizontal part can also block the view at the connection between the front end of the horizontal part and the lower section of the tailgate outer panel, making the connection less visible and reducing the assembly process requirements at this location.

Detailed Implementation

[0033] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0034] like Figures 1-7 As shown, a segmented tailgate structure in this embodiment includes a tailgate outer panel assembly. The tailgate outer panel assembly includes an upper tailgate outer panel 1, a middle tailgate outer panel 2, and a lower tailgate outer panel 3. The upper part of the middle tailgate outer panel 2 is connected to the lower part of the upper tailgate outer panel 1, and the lower part of the middle tailgate outer panel 2 is connected to the upper part of the lower tailgate outer panel 3. The middle tailgate outer panel 2 integrates a taillight cover function.

[0035] In this embodiment, the upper section 1 and the lower section 3 of the tailgate outer panel are both single-color injection molded parts made of non-transparent material, and the middle section 2 of the tailgate outer panel is a double-layer, two-color injection molded part made of transparent and non-transparent material.

[0036] In this embodiment, the middle section 2 of the tailgate outer panel includes a first opaque area 201, a translucent area 202, and a second opaque area 203. The upper part of the translucent area 202 is connected to the lower part of the first opaque area 201, and the lower part of the translucent area 202 is connected to the upper part of the second opaque area 203. There is a gap between the first opaque area 201 and the second opaque area 203. The middle part of the translucent area 202 corresponds to the position of the gap to realize the function of integrating the taillight cover.

[0037] By dividing the tailgate outer panel assembly into three sections, the product structure can be simplified. The upper section 1, middle section 2, and lower section 3 of the tailgate outer panel are processed separately, which facilitates injection molding and avoids sacrificing part of the structure to ensure injection molding and demolding. The segmented structure and shape are more flexible. The processes and materials of the upper section 1, middle section 2, and lower section 3 of the tailgate outer panel can also be different. The process of integrating the taillight cover function in the middle section 2 is more complex, and the material also needs to be light-transmitting. Only the middle part of the tailgate outer panel assembly uses double-layer injection molding. The entire tailgate outer panel assembly does not need to use a large area of ​​double-layer injection molding, which reduces the requirements for injection molding equipment, reduces equipment investment, reduces labor costs, reduces material usage, reduces product costs, and achieves lightweighting.

[0038] Furthermore, the taillight cover function is integrated into the middle section 2 of the tailgate outer panel, eliminating the need for a separate taillight cover component, thus reducing the weight of the tailgate. It also eliminates the assembly gap and surface difference between the taillight cover and the tailgate outer panel. The connection position between the taillight housing 5, which runs through the taillight, and the middle section 2 of the tailgate outer panel can be set after the first non-transparent area 201 and the second non-transparent area 203. The fit gap, surface difference, and adhesive structure between the taillight housing 5 and the middle section 2 of the tailgate outer panel are all hidden by the non-transparent area 202 and are not visible from the outside. This effectively solves the problems of large and uneven gaps, uneven surface differences, low matching pass rate, and long assembly time in the installation and matching of traditional through-type taillights, and can further improve the appearance.

[0039] The middle section 2 of the tailgate outer panel is injection molded from two-color materials in one step. The middle section 2 can be molded using PMMA or PC materials. If PMMA material is used, no treatment is required on the outer surface of the middle section 2. If PC material is used, UV-cured paint must be sprayed onto the outer surface of the middle section 2. The upper section 1 and lower section 3 of the tailgate outer panel are made of non-transparent materials, such as non-transparent PC, non-transparent PC+ABS, PP, or modified PP.

[0040] In this embodiment, the segmented tailgate structure further includes an inner tailgate panel 4 and a taillight housing 5. The inner tailgate panel 4 is disposed on the front side of the outer tailgate panel assembly, and the taillight housing 5 is disposed between the middle section 2 of the outer tailgate panel and the inner tailgate panel 4. Preferably, the taillight housing 5 is a housing that extends through the taillight.

[0041] In this embodiment, the segmented tailgate structure further includes a tailgate glass 6. The upper section 1 of the outer tailgate panel has an inverted "U" shape. The left, upper, and right parts of the tailgate glass 6 are all connected to the upper section 1 of the outer tailgate panel. The lower part of the tailgate glass 6 is connected to the inner tailgate panel 4, and there is an accommodating space between the lower end of the tailgate glass 6 and the inner tailgate panel 4. The upper end of the first non-transparent area 201 extends into the accommodating space. The upper section 1 of the outer tailgate panel has an inverted "U" shape, and the two lower ends on the left and right sides of its opening are connected to the middle section 2 of the outer tailgate panel.

[0042] The lower end of the tailgate glass 6 is on the outside, and the upper end of the middle section 2 of the tailgate outer panel is on the inside. This structure ensures that the joint is smooth and without steps. When water flows from top to bottom, the resistance is small and water does not easily accumulate. At the same time, it also serves as a waterproof function.

[0043] In this embodiment, the first non-transparent area 201 includes a first upwardly inclined portion 2011, a first middle inclined portion 2012, and a first downwardly inclined portion 2013 arranged sequentially from top to bottom. The first upwardly inclined portion 2011 tilts backward from top to bottom, the first middle inclined portion 2012 tilts forward from top to bottom, and the first downwardly inclined portion 2013 tilts backward from top to bottom. A forward-extending first mounting portion 2014 is provided at the connection between the first middle inclined portion 2012 and the first downwardly inclined portion 2013; the second non-transparent area 203 includes a second upper inclined portion 2031, a second middle inclined portion 2032, and a second lower bent portion arranged sequentially from top to bottom. The second upper inclined portion 2031 is inclined forward from top to bottom, and the second middle inclined portion 2032 is inclined backward from top to bottom. A second mounting portion 2035 extending forward is provided at the connection between the second upper inclined portion 2031 and the second middle inclined portion 2032. The first mounting portion 2014 and the second mounting portion 2035 are both connected to the taillight housing 5 by plastic welding or bonding.

[0044] The positions of the first mounting part 2014 and the second mounting part 2035 are both non-transparent areas 202. The mating gap, surface difference and adhesive structure between the taillight housing 5 and the middle section 2 of the tailgate outer panel are all hidden by the non-transparent areas 202 and are not visible from the outside.

[0045] Both the tailgate glass 6 and the first upward-sloping portion 2011 are inclined backward from top to bottom, resulting in less resistance when water flows downward and less water accumulation. Furthermore, preferably, the rear apex of the corner connecting the first upward-sloping portion 2011 and the first middle-sloping portion 2012 is positioned further back than the light-transmitting area 202, giving the first upward-sloping portion 2011 and the first middle-sloping portion 2012 a certain rain-shielding effect. After rainwater carrying impurities flows down from the tailgate glass 6 and the first upward-sloping portion 2011, it does not fall onto the light-transmitting area 202, reducing turbid liquid stains on the light-transmitting area 202.

[0046] In this embodiment, the second lower bending portion includes a vertical portion 2033 arranged in the up-down direction and a horizontal portion 2034 arranged in the front-back direction. The vertical portion 2033 is connected to the second middle inclined portion 2032. The front end of the horizontal portion 2034 is connected to the lower section 3 of the tailgate outer panel. The middle part of the horizontal portion 2034 is provided with a license plate light mounting hole 2036. A license plate mounting structure 301 is provided on the lower section 3 of the tailgate outer panel. The license plate mounting structure 301 is located below the license plate light mounting hole 2036.

[0047] A license plate light mounting hole 2036 is integrated on the lower section 3 of the tailgate outer panel, allowing a license plate light to be installed at this location. The license plate light provides illumination to the license plate mounting structure 301. The license plate light mounting hole 2036 runs vertically. After dividing the tailgate outer panel into three sections, the structure of the lower section 3 of the tailgate outer panel is simple, and the structure of the license plate light mounting hole 2036 does not affect the injection molding and demolding of the lower section 3 of the tailgate outer panel.

[0048] The horizontal section 2034 can also block the view at the connection between the front end of the horizontal section 2034 and the lower section 3 of the tailgate outer panel, making the connection less visible and reducing the assembly process requirements at that point.

[0049] It is worth noting that the vertical portion 2033 being arranged along the vertical direction does not mean that the vertical portion 2033 is completely parallel to the vertical direction; a small angle between the vertical portion 2033 and the vertical direction is allowed. Similarly, the horizontal portion 2034 being arranged along the front-back direction does not mean that the horizontal portion 2034 is completely parallel to the front-back direction; a small angle between the horizontal portion 2034 and the front-back direction is allowed. The angle between the vertical portion 2033 and the horizontal portion 2034 can be 85°-95°.

[0050] In this embodiment, the upper section 1 of the outer tailgate panel and the middle section 2 of the outer tailgate panel, the upper section 1 of the outer tailgate panel and the inner tailgate panel 4, the middle section 2 of the outer tailgate panel and the inner tailgate panel 4, the tailgate glass 6 and the upper section 1 of the outer tailgate panel, the tailgate glass 6 and the inner tailgate panel 4, and the lower section 3 of the outer tailgate panel and the inner tailgate panel 4 are all connected by adhesive bonding; the middle section 2 of the outer tailgate panel and the lower section 3 of the outer tailgate panel are connected by snap-fit ​​and adhesive bonding.

[0051] A soft adhesive, structural adhesive, or other adhesive 7 is applied at the bonding location, serving both a bonding and sealing function.

[0052] like Figure 7 As shown, the middle section 2 and the lower section 3 of the tailgate outer panel are connected by a combination of snap-fit ​​and adhesive. Since the horizontal part 2034 is positioned along the front-to-back direction, the overlap with the lower section 3 of the tailgate outer panel is small; therefore, both snap-fit ​​and adhesive methods are used. Of course, as... Figure 6 As shown, the middle section 2 of the tailgate outer panel and the lower section 3 of the tailgate outer panel can also be connected by adding an overlapping structure and adhesive bonding.

[0053] like Figure 8 As shown, this embodiment illustrates a tailgate assembly process for assembling a segmented tailgate structure, comprising the following steps:

[0054] S1. Assemble the middle section 2 of the tailgate outer panel and the taillight housing 5 to form a first assembly assembly;

[0055] S2. Assemble the first assembly assembly with the lower section 3 of the tailgate outer panel to form the second assembly assembly;

[0056] S3. Assemble the second assembly assembly, the upper section of the outer panel, and the inner panel 4 of the tailgate to form the third assembly assembly;

[0057] S4. Assemble the third assembly component and the tailgate glass 6.

[0058] With the increased number of tailgate parts and the fact that they are primarily glued together, the assembly sequence of these parts is crucial. The tailgate assembly process in this embodiment reduces material turnover, the number of tooling components, and the floor space required for assembly, making it a relatively economical assembly solution.

[0059] One vehicle in this embodiment is characterized by including a segmented tailgate structure.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
