Description

Technical Field

[0001] This utility model relates to vehicle structure, specifically to a segmented tailgate structure and a 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. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a segmented tailgate structure and vehicle, which reduces the requirements for injection molding equipment, reduces equipment investment, and at the same time achieves lightweighting and improves the appearance.

[0004] This utility model discloses a segmented tailgate structure, including a tailgate outer panel assembly. The tailgate outer panel assembly 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 light-transmitting area, and the middle section of the tailgate outer panel also includes a first non-light-transmitting area, a second non-light-transmitting area, and a third non-light-transmitting area disposed on the front side of the light-transmitting area. There is a first gap between the first non-light-transmitting area and the second non-light-transmitting area, and a second gap between the second non-light-transmitting area and the third non-light-transmitting area.

[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. The upper part of the taillight housing is connected to the first opaque area, the middle part of the taillight housing is connected to the second opaque area, and the lower part of the taillight housing is connected to the third opaque area.

[0008] Furthermore, the first non-transparent area includes a first inclined portion, a first light-shielding portion, and a first connecting portion. The first inclined portion slopes backward from top to bottom. The first light-shielding portion is located on the lower side of the first inclined portion. The first connecting portion is located on the front side of the first light-shielding portion. The first connecting portion is connected to the upper part of the taillight housing by plastic welding or bonding. The second non-transparent area includes a second light-shielding portion and a second connecting portion. The second connecting portion is located on the front side of the second light-shielding portion. The second connecting portion is connected to the middle part of the taillight housing by plastic welding or bonding. The third non-transparent area includes a third light-shielding portion and a third connecting portion. The third connecting portion is located on the front side of the third light-shielding portion. The third connecting portion is connected to the lower part of the taillight housing by plastic welding or bonding.

[0009] Furthermore, the taillight housing includes a first mounting cavity for accommodating a multi-functional interactive taillight and a second mounting cavity for accommodating a conventional lighting taillight; the first mounting cavity is located between the first connecting portion and the second connecting portion, and the second mounting cavity is located between the second connecting portion and the third connecting portion.

[0010] 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 light-transmitting area and the upper end of the first non-light-transmitting area extend into the accommodating space.

[0011] Furthermore, the light-transmitting area includes a first light-transmitting part, a second light-transmitting part, a third light-transmitting part, and a fourth light-transmitting part arranged sequentially from top to bottom.

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.

[0013] This utility model relates to a vehicle, which includes a segmented tailgate structure.

[0014] The beneficial effects of this utility model are:

[0015] (1) This utility model simplifies the product structure by dividing the tailgate outer panel assembly into three sections. 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 tailgate outer panel assembly as a whole 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.

[0016] (2) The taillight cover function is integrated in the middle section of the tailgate outer panel of this utility model. It does not require a separate taillight cover component, which reduces 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 and the middle section of the tailgate outer panel can be set after the first non-transparent area, the second non-transparent area and the third 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.

Detailed Implementation

[0024] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1-5 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.

[0026] 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.

[0027] In this embodiment, the middle section 2 of the tailgate outer panel includes a light-transmitting area 201. The middle section 2 of the tailgate outer panel also includes a first non-light-transmitting area 202, a second non-light-transmitting area 203, and a third non-light-transmitting area 204 disposed on the front side of the light-transmitting area 201. There is a first gap between the first non-light-transmitting area 202 and the second non-light-transmitting area 203, and there is a second gap between the second non-light-transmitting area 203 and the third non-light-transmitting area 204.

[0028] 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.

[0029] 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 202, the second non-transparent area 203, and the third non-transparent area 204. 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 201 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.

[0030] In this embodiment, the segmented tailgate structure further includes a tailgate inner panel 4 and a taillight housing 5. The tailgate inner panel 4 is disposed on the front side of the tailgate outer panel assembly, and the taillight housing 5 is disposed between the middle section 2 of the tailgate outer panel and the tailgate inner panel 4. The upper part of the taillight housing 5 is connected to the first opaque area 202, the middle part of the taillight housing 5 is connected to the second opaque area 203, and the lower part of the taillight housing 5 is connected to the third opaque area 204.

[0031] In this embodiment, the first non-transparent area 202 includes a first inclined portion 2021, a first light-shielding portion 2022, and a first connecting portion 2023. The first inclined portion 2021 is inclined backward from top to bottom. The first light-shielding portion 2022 is located below the first inclined portion 2021. The first connecting portion 2023 is located in front of the first light-shielding portion 2022. The first connecting portion 2023 is connected to the upper part of the taillight housing 5 by plastic welding or bonding. The second non-transparent area 203 includes a second light-shielding portion. The third non-transparent area 204 includes a third light-shielding part 2041 and a third connecting part 2032. The second connecting part 2032 is located in front of the second light-shielding part 2031 and is connected to the middle part of the taillight housing 5 by plastic welding or bonding. The third non-transparent area 204 includes a third light-shielding part 2041 and a third connecting part 2042. The third connecting part 2042 is located in front of the third light-shielding part 2041 and is connected to the lower part of the taillight housing 5 by plastic welding or bonding.

[0032] In this embodiment, the taillight housing 5 includes a first mounting cavity 501 for accommodating a multi-functional interactive taillight and a second mounting cavity 502 for accommodating a conventional lighting taillight; the first mounting cavity 501 is located between the first connecting portion 2023 and the second connecting portion 2032, and the second mounting cavity 502 is located between the second connecting portion 2032 and the third connecting portion 2042.

[0033] 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 can be made of opaque PP polypropylene composite material, opaque modified PP material, opaque PC material, or opaque PC+ABS material. The second light-transmitting part 2012 of the middle section 2 of the tailgate outer panel can use in-mold transfer technology to form a specific pattern, which, in conjunction with the lighting of the multi-functional interactive taillights, displays information to the user.

[0034] After the taillight housing 5 is fitted with a multi-functional interactive taillight through the first cavity and a conventional lighting taillight through the second cavity, the multi-functional interactive taillight can display welcome light patterns and scene interaction patterns through the second light-transmitting part 2012 corresponding to the first gap, and the conventional lighting taillight can display traditional lights through the third light-transmitting part 2013 corresponding to the second gap. The front surface of the fourth light-transmitting part 2014 is provided with an opaque paint, which can be black paint sprayed on the front surface of the fourth light-transmitting part 2014, making the fourth light-transmitting part 2014 no longer transparent and able to cover the internal structure.

[0035] 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. 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 light-transmitting area 201 and the upper end of the first non-light-transmitting area 202 extend into the accommodating space.

[0036] With the lower end of the tailgate glass 6 facing outwards and the upper end of the middle section 2 of the tailgate outer panel facing inwards, this structure ensures a smooth, stepless joint, minimizes water resistance as water flows downwards, prevents water accumulation, and also serves a waterproof function.

[0037] In this embodiment, the light-transmitting area 201 includes a first light-transmitting part 2011, a second light-transmitting part 2012, a third light-transmitting part 2013, and a fourth light-transmitting part 2014 arranged sequentially from top to bottom. The first light-transmitting part 2011 corresponds to the position of the first inclined part 2021. The second light-transmitting part 2012 and the third light-transmitting part 2013 both correspond to the position of the taillight housing 5. The fourth light-transmitting part 2014 is located on the lower side of the taillight housing 5, and the front surface of the fourth light-transmitting part 2014 is provided with an opaque paint.

[0038] In this embodiment, the fourth light-transmitting part 2014 includes a fourth inclined part, a vertical part arranged in the up-down direction, and a horizontal part arranged in the front-back direction. The vertical part is connected to the fourth inclined part, and the front end of the horizontal part is connected to the lower section 3 of the tailgate outer panel. The middle part of the horizontal part is provided with a license plate light mounting hole 2015. A license plate mounting structure 301 is provided on the lower section 3 of the tailgate outer panel, and the license plate mounting structure 301 is located below the license plate light mounting hole 2015.

[0039] It is worth noting that the vertical part being set along the up-down direction does not mean that the vertical part is completely parallel to the up-down direction; a small angle between the vertical part and the up-down direction is allowed. Similarly, the horizontal part being set along the front-back direction does not mean that the horizontal part is completely parallel to the front-back direction; a small angle between the horizontal part and the front-back horizontal plane is allowed. The angle between the horizontal part and the horizontal plane in the front-back direction can be 3° to 8°.

[0040] A license plate light mounting hole 2015 is integrated on the lower section 3 of the tailgate outer panel, which allows the license plate light to be installed at this location. The license plate light can provide illumination for the license plate mounting structure 301.

[0041] 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.

[0042] A soft adhesive, structural adhesive, or other adhesive 7 is applied at the bonding location, serving both a connection and sealing function. The middle section 2 of the tailgate outer panel and the lower section 3 of the tailgate outer panel are connected by a combination of snap-fit ​​and adhesive. Since the horizontal part is set along the front-to-back direction, the overlap size with the lower section 3 of the tailgate outer panel is small, so both snap-fit ​​and adhesive connection methods are used.

[0043] One vehicle in this embodiment includes a segmented tailgate structure.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model 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 this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
