Description

Technical Field

[0001] The utility model relates to the technical field of automobile tailgates, in particular to an outer panel split type tailgate. Background Art

[0002] With the continuous advancement of automotive technology, such as electrification and intelligentization, the design of vehicle rear ends is also evolving to meet consumers' demand for aesthetics and personalization. As vehicle rear end styling becomes more complex and the demand for color matching increases, the tailgate outer panel is often split into two parts, called a split tailgate.

[0003] In order to achieve the connection and sealing of the upper and lower parts of the tailgate outer panel, there are usually two existing installation methods. The first option is to extend one of the split outer panels to overlap with the other outer panel, and bond it to the tailgate inner panel on the tire mold to achieve connection and sealing. Then, the other outer panel is installed in the overlapping part as an additional decorative part. This method is relatively expensive. The second option is to first bond the two split outer panels on the tire mold to achieve connection and sealing between the two. After the glue is cured, it is bonded to the tailgate inner panel on the tire mold to achieve overall connection and sealing. Although this method has lower material costs than the first option, due to the additional bonding process, additional bonding process costs and bonding tire mold costs, as well as corresponding site usage costs and logistics costs, the total cost is still high. In addition, in this method, the two outer panels cannot be structurally positioned and can only be indirectly positioned by bonding the tire mold, so a larger gap needs to be set, which cannot achieve the requirements of exquisite appearance matching.

[0004] The above-mentioned split tailgate installation methods all have disadvantages such as complicated operation, high cost, and inability to achieve tight sealing of the tailgate outer panel and the tailgate inner panel. Therefore, it is urgent to develop a new outer panel split tailgate to achieve tight sealing of the outer panel and the tailgate inner panel. Utility Model Content

[0005] The purpose of the utility model is to provide a tailgate with a split outer panel, so as to achieve fastening and sealing of the tailgate outer panel and the tailgate inner panel.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A split-outer-panel tailgate comprises an upper tailgate outer panel, a lower tailgate outer panel, and an inner tailgate panel, wherein the upper tailgate outer panel, the lower tailgate outer panel, and the inner tailgate panel are all connected to each other by bonding, and a waterproof cavity is formed between the three tailgate panels;

[0008] A C-shaped slot opening outwards of the tailgate is horizontally provided at the upper end of the lower tailgate outer panel, and an assembly space is formed between the upper tailgate outer panel and the C-shaped slot of the lower tailgate outer panel. A plurality of clamping positions are arranged at intervals in the assembly space, and a pre-fixed clamping structure is provided at each clamping position.

[0009] Furthermore, a first adhesive layer is provided between the upper tailgate outer panel and the inner tailgate panel, a second adhesive layer is provided between the upper tailgate outer panel and the lower tailgate panel, and a third adhesive layer is provided between the lower tailgate outer panel and the inner tailgate panel.

[0010] Furthermore, the first adhesive layer, the second adhesive layer and the third adhesive layer are all glue layers with continuous adhesive paths, and the boundaries of the adhesive paths overlap with each other.

[0011] Furthermore, the three tailgate panels are bonded to each other to form a waterproof cavity.

[0012] Furthermore, the single-side cross-sectional dimension of the C-shaped slot at the non-clamping position is smaller than the single-side cross-sectional dimension at the clamping position.

[0013] Furthermore, the upper plate of the tailgate outer panel is provided with a flange that can extend into the assembly space.

[0014] Furthermore, the C-shaped slot at the non-clamping position cooperates with the flange gap, and the gap is no more than 0.2 mm, thereby ensuring that the gap and surface difference between the upper and lower panels of the tailgate outer panel are matched.

[0015] Furthermore, a protruding structure is provided on the C-shaped slot at the clamping position, and a clamping hole that can be clamped with the protruding structure is opened on the flange. The protruding structure and the clamping hole constitute the pre-fixed clamping structure, which is used for pre-fixation before the glue is cured.

[0016] Furthermore, the pre-fixed clamping structures are arranged at equal intervals.

[0017] Furthermore, a shielding rib is provided on the upper plate of the tailgate outer panel, and the shielding rib runs through the seam connection area of ​​the upper plate and the lower plate of the tailgate outer panel, which can effectively prevent the pre-fixed clip structure from being directly seen from the outside and affecting the appearance.

[0018] Furthermore, the shielding rib is fitted with a clearance between the lower plate of the tailgate outer panel, and the clearance is no more than 0.5 mm.

[0019] Furthermore, a support structure is provided on the tailgate inner panel, and the support structure is bonded to the C-shaped slot to avoid difficulties in the installation process caused by the flipping and deformation of the C-shaped slot.

[0020] Furthermore, the outer panel split tailgate can be installed by any of the following two methods.

[0021] The first method specifically includes the following steps: installing the upper plate of the tailgate outer panel onto the outer panel mold, and applying a second adhesive layer on the corresponding position of the upper plate of the tailgate outer panel; installing the lower plate of the tailgate outer panel onto the outer panel mold, pressing the second adhesive layer and the pre-fixed clamping structure, and then applying the first adhesive layer and the third adhesive layer; placing the inner panel on the inner panel mold, and then closing the outer panel mold with the inner panel mold to complete the installation.

[0022] The second method specifically includes the following steps: installing the upper plate and the lower plate of the tailgate outer panel on the outer panel mold at the same time, wherein the first tire module where the upper plate of the tailgate outer panel is located and the second tire module where the lower plate of the tailgate outer panel is located are staggered on the outer panel mold; applying the first adhesive layer and the second adhesive layer on the upper plate of the tailgate outer panel, and applying the third adhesive layer on the lower plate of the tailgate outer panel, to ensure that the overlapping positions between the adhesive layers are continuous; placing the tailgate inner panel on the inner panel mold, and the outer panel mold with the first tire module and the second tire module is molded with the inner panel mold; the motion mechanism drives the first tire module to continue pressing to complete the installation.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) The utility model provides a split-outer-panel tailgate with an adhesive path and a pre-fixed snap-in structure, so that the two tailgate outer panels can be bonded to the tailgate inner panel at the same time, and the two tailgate outer panels can be effectively bonded to each other at the same time, thereby achieving the fastening and sealing of the split-outer-panel tailgate outer panel and the tailgate inner panel.

[0025] (2) The present invention takes into account that the adhesive path between the two tailgate outer panels is blocked by the inner panel structure, so that the adhesive layer cures quickly. Therefore, a pre-fixed clamping structure is arranged at intervals above the adhesive path between the two tailgate outer panels to pre-fix the two tailgate outer panels before the adhesive layer cures.

[0026] (3) The boundaries of the adhesive paths of the present invention overlap with each other, which can ensure that no water can enter the waterproof cavity inside the adhesive path, thereby achieving an effective sealing function.

[0027] (4) The present invention takes into account the overall aesthetics of the split-outer-panel tailgate, and provides a through-shielding rib in the seam connection area between the upper and lower tailgate outer panels, which can effectively prevent the pre-fixed snap-in structure from being directly seen from the outside and affecting the aesthetics.

[0028] (5) In the split-outer-panel tailgate of the present invention, there is no need to set a large gap between the two tailgate outer panels, which can achieve exquisite appearance matching requirements.

[0029] (6) The outer panel split tailgate of the utility model can be installed through two installation methods and different outer panel membranes are selected. The installation method is flexible, the operation is simple, and it has good practical application value. BRIEF DESCRIPTION OF THE DRAWINGS

The first adhesive layer 4, the second adhesive layer 5, and the third adhesive layer 6 are all adhesive layers with continuous adhesive paths. The boundaries of each adhesive path overlap, ensuring that water cannot enter the waterproof cavity 7 inside the adhesive path, thus achieving a sealing function.

[0056] Example 3:

[0057] A tailgate with a split outer panel comprises an upper tailgate outer panel 1, a lower tailgate outer panel 2, and an inner tailgate panel 3. The upper tailgate outer panel 1, the lower tailgate outer panel 2, and the inner tailgate panel 3 are all bonded together, and the three tailgate panels are bonded together to form a waterproof cavity 7. A C-shaped slot 21 opening outward from the tailgate is horizontally defined at the upper end of the lower tailgate outer panel 2. An assembly space is formed between the C-shaped slot 21 of the upper tailgate outer panel 1 and the lower tailgate outer panel 2. Multiple snap-in locations are spaced apart within the assembly space, each of which is provided with a pre-fixed snap-in structure.

[0058] The cross-sectional dimensions of the C-shaped slot 21 at the non-engaging position are smaller than those at the engaging position. Figure 4 As shown, the tailgate outer panel upper panel 1 is equipped with a flange 11 that extends into the assembly space. A C-shaped slot 21 in the non-engaging position has a clearance fit with the flange 11, with the clearance no greater than 0.2 mm. A protrusion 22 is provided on the C-shaped slot 21 in the engaging position, and a snap-in hole 12 is provided on the flange 11 that snaps into the protrusion 22. The protrusion 22 on the tailgate outer panel lower panel 2 and the snap-in hole 12 on the tailgate outer panel upper panel 1 together form a pre-fixed snap-in structure, pre-fixing the tailgate outer panel upper panel 1 and the tailgate outer panel lower panel 2 before the adhesive cures, accelerating the subsequent curing of the adhesive layer.

[0059] Example 4:

[0060] A tailgate with a split outer panel comprises an upper tailgate outer panel 1, a lower tailgate outer panel 2, and an inner tailgate panel 3. The upper tailgate outer panel 1, the lower tailgate outer panel 2, and the inner tailgate panel 3 are all bonded together, and the three tailgate panels are bonded together to form a waterproof cavity 7. A C-shaped slot 21 opening outward from the tailgate is horizontally defined at the upper end of the lower tailgate outer panel 2. An assembly space is formed between the C-shaped slot 21 of the upper tailgate outer panel 1 and the lower tailgate outer panel 2. Multiple snap-in locations are spaced apart within the assembly space, each of which is provided with a pre-fixed snap-in structure.

[0061] In order to prevent the clamping structure from being directly seen from the outside of the tailgate, affecting the overall aesthetics, Figure 5As shown, in this embodiment, a shielding rib 13 is further provided on the tailgate outer panel upper plate 1. The shielding rib 13 extends through the seam connection area between the tailgate outer panel upper plate 1 and the tailgate outer panel lower plate 2. A clearance between the shielding rib 13 and the tailgate outer panel lower plate 2 is provided, and the clearance is no greater than 0.5 mm.

[0062] Example 5:

[0063] A tailgate with a split outer panel comprises an upper tailgate outer panel 1, a lower tailgate outer panel 2, and an inner tailgate panel 3. The upper tailgate outer panel 1, the lower tailgate outer panel 2, and the inner tailgate panel 3 are all bonded together, and a waterproof cavity 7 is formed between the three tailgate panels. A C-shaped slot 21 opening outward from the tailgate is horizontally defined at the upper end of the lower tailgate outer panel 2. An assembly space is formed between the C-shaped slot 21 of the upper tailgate outer panel 1 and the lower tailgate outer panel 2. Multiple snap-in locations are spaced apart within the assembly space, each of which is provided with a pre-fixed snap-in structure.

[0064] In order to avoid difficulties in the installation process caused by the flipping and deformation of the C-shaped slot 21 , a support structure 31 is provided on the tailgate inner panel 3 of this embodiment, and the support structure 31 is bonded to the C-shaped slot 21 .

[0065] Example 6:

[0066] This embodiment provides a split-outer-panel tailgate and a specific installation method thereof. The split-outer-panel tailgate includes a structure that allows the two split tailgate outer panels to be bonded to the tailgate inner panel at once. Specifically, a connection structure with a pre-fixed clamping structure and a bonding path allows the two tailgate outer panels to be bonded to the tailgate inner panel simultaneously, and the two tailgate outer panels to be bonded to each other simultaneously. Because the bonding path between the two tailgate outer panels is blocked by the tailgate inner panel, the glue therein cannot be quickly cured by the heating and curing device on the mold like the glue in other parts. In order not to affect the production cycle, pre-fixed clamping structures are arranged at intervals above the bonding path between the two outer panels to pre-fix the two tailgate outer panels before the glue cures.

[0067] The split-outer-panel tailgate of this embodiment comprises an upper tailgate outer panel 1, a lower tailgate outer panel 2, and an inner tailgate panel 3. The three tailgate panels are connected by glue. The glue creates a continuous glue path, with overlapping edges. This prevents water from entering the inner side of the glue path, i.e., the waterproof cavity 7 formed by the upper tailgate outer panel 1, the lower tailgate outer panel 2, and the inner tailgate panel 3, thus achieving a sealing effect.

[0068] The upper end of the tailgate outer panel lower plate 2 includes a C-shaped slot 21. This structure encloses the flange 11 at the lower end of the tailgate outer panel upper plate 1, ensuring the gap and face difference between the tailgate outer panel upper plate 1 and the tailgate outer panel lower plate 2 match. To ensure good assembly, the clearance between the C-shaped slot 21 and the flange 11 is set to 0-0.2mm. The C-shaped slot 21 is enlarged at the required engagement location and has a raised structure 22. The corresponding engagement hole 12 is opened at the position of the flange 11. The raised structure 22 and the engagement hole 12 together form a pre-fixed engagement structure for pre-fixation before the glue cures.

[0069] In order to prevent the pre-fixed clip structure from being directly seen from the outside and affecting the appearance, a shielding rib 13 is further provided on the upper plate 1 of the tailgate outer panel. The shielding rib 13 runs through the entire seam area between the upper plate 1 of the tailgate outer panel and the lower plate 2 of the tailgate outer panel, and the gap between the shielding rib 13 and the lower plate 2 of the tailgate outer panel is set to 0 to 0.5 mm.

[0070] In addition, a support structure 31 is provided on the inner panel 3 to prevent installation difficulties caused by the C-shaped slot 21 being tilted and deformed. Since the above structure is built below the glue path formed by the glue (second adhesive layer 5), that is, outside the cavity 5, it does not affect the overall sealing function.

[0071] Figure 6 This embodiment demonstrates the first installation method for a split-outer-panel tailgate. First, the tailgate outer panel upper panel 1 is mounted on the outer panel mold 8. Glue (second adhesive layer 5) is applied to the corresponding position of the tailgate outer panel upper panel 1. The tailgate outer panel lower panel 2 is then mounted on the outer panel mold 8, thereby laminating the second adhesive layer 5 and engaging the protrusion 22 with the engagement hole 12. The first adhesive layer 4 and third adhesive layer 6 are then applied, ensuring a continuous overlap between them and with the second adhesive layer 5. Simultaneously, the tailgate inner panel 3 is placed on the inner panel mold 9. The outer panel mold 8 and inner panel mold 9 are then joined together to connect the inner and outer panels.

[0072] Figure 7This embodiment demonstrates a second installation method for a split-outer-panel tailgate. First, the tailgate outer panel upper panel 1 and tailgate outer panel lower panel 2 are simultaneously installed on the outer panel mold 8. To ensure that the second adhesive layer 5 can be applied to the corresponding position of the tailgate outer panel upper panel 1, the first mold module 81 for the tailgate outer panel upper panel 1 and the second mold module 82 for the tailgate outer panel lower panel 2 are staggered on the outer panel mold 8. The first mold module 81 is positioned relatively rearward and can be moved forward to the desired position via a motion mechanism 83 (a conventional telescopic cylinder can be used). Next, the first adhesive layer 4 and the second adhesive layer 5 are applied to the tailgate outer panel upper panel 1, ensuring that the overlapping position between the two is continuous. Simultaneously, the third adhesive layer 6 is applied to the tailgate outer panel lower panel 2, ensuring that the overlapping position between the third adhesive layer 6 and the first adhesive layer 4 and the second adhesive layer 5 is continuous after lamination. At the same time, the tailgate inner panel 3 is placed on the inner panel mold 9. Then, the outer panel mold 8, with the first and second mold modules 81 and 82, is molded together with the inner panel mold 9, thus connecting the tailgate outer lower panel 2 to the tailgate inner panel 3. At this point, the tailgate outer panel upper panel 1 is still separated from the inner panel 3 and the tailgate outer lower panel 2. Then, the motion mechanism 83 drives the first mold module 81 to continue pressing together, thus connecting the inner and outer panels.

[0073] The above description of the embodiments is intended to facilitate understanding and use of the utility model by those skilled in the art. Those skilled in the art will readily be able to make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the utility model is not limited to the above-described embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of this utility model without departing from the scope of this utility model should be within the scope of protection of this utility model.
