[0029] With the popularization of vehicles, people's requirements for vehicle usage experience are further improved. The outer triangle plate between the front door and the A-pillar of the car is of great significance to the sealing and NVH (noise, vibration and harshness) performance of the vehicle. However, the current outer triangle plate is located on the outside of the vehicle and ages quickly under wind and sun. There is a risk of soft rubber falling off, which will affect the sealing and noise reduction performance inside the vehicle.

[0030] In order to make the technical personnel in this field better understand the present invention, the embodiments of the present invention are described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary for the solutions of the utility model described in the claims.

[0031] See also Figure 1-3 The outer triangle plate provided by the embodiment of the utility model includes a hard rubber part 10 and a soft rubber part 20. Specifically, the hard rubber part 10 and the soft rubber part 20 are formed into an integrated structure through a two-color injection molding process. It should be noted here that the two-color injection molding specifically refers to the hard rubber part 10 and the soft rubber part 20 using different materials during injection molding. The hard rubber part 10 maintains a stable shape structure after molding, and the soft rubber part 20 has a certain elasticity after molding, and achieves a sealing effect when being pressed and assembled. The hard rubber part 10 and the soft rubber part 20 are combined to form a triangle plate configuration to meet the use It should be noted that the hard rubber part 10 is preferably made of high-strength plastic material, such as ABS plastic, to ensure the stability and durability of its structure. At the same time, the hard rubber part 10 serves as a basic bearing structure, which includes a supporting surface 110 for contacting the soft rubber part 20. It should be noted that the supporting surface 110 is preferably a flat structure with a certain degree of roughness on the surface. For example, it can be designed with a texture configuration or particles that increase the friction coefficient to increase the friction between the supporting surface 110 and the soft rubber part 20 to ensure that the two are tightly combined.

[0032] On the basis of the above structure, a plurality of connecting ribs 120 with raised structures are arranged at intervals on the support surface 110. The connecting ribs 120 are integrally formed with the hard rubber part 10 by an injection molding process, thereby ensuring the strength of the connecting ribs 120 and the integrity with the hard rubber part 10. Correspondingly, a plurality of locking grooves 210 are provided at the positions of the connecting ribs 120 of the hard rubber part 10 on the soft rubber part 20. The shapes of the locking grooves 210 match the connecting ribs 120 to ensure that the connecting ribs 120 can be accurately inserted therein. The connecting ribs 120 are formed one by one in the locking grooves 210. Each locking groove 210 has a corresponding connection with a connecting rib 120. At the same time, the end of the connecting rib 120 away from the support surface 110 also protrudes from the locking groove 210, and a locking block 130 is formed by hot riveting welding, see Figure 3 and Figure 4The cross-sectional dimension of the locking block 130 is larger than the cross-sectional dimension of the locking groove 210, so that the locking groove 210 cannot escape from the locking block 130 position. The locking block 130 can be rectangular or circular, etc. In a specific embodiment of the utility model, the locking block 130 is a mushroom-shaped configuration to lock the soft rubber part 20. The setting of the locking block 130 increases the contact area between the connecting rib 120 and the soft rubber part 20, provides a stronger locking effect, and at the same time cooperates to form a structural form in which both sides of the soft rubber part 20 are clamped and locked by the supporting surface 110 and the locking block 130. When the outer triangle plate is assembled on the vehicle body, the soft rubber part 20 is compressed and produces a certain amount of deformation. At this time, the area between the supporting surface 110 and the locking block 130 will be further filled, and the squeezing effect between the soft rubber part 20 and the hard rubber part 10 is stronger, so that the two maintain a stable connection state.

[0033] The outer triangular plate provided by the embodiment of the utility model is based on the current two-color injection molding of the hard rubber part 10 and the soft rubber part 20. A plurality of connecting ribs 120 are arranged at intervals on the supporting surface 110 in the hard rubber part 10 that contacts the soft rubber part 20, so as to be inserted into the locking groove 210 area correspondingly arranged on the soft rubber part 20, so that the soft rubber part 20 and the hard rubber part 10 are more closely combined. At the same time, the design height of the connecting rib 120 enables it to be inserted into the locking groove 210 while the end away from the supporting surface 110 protrudes out of the locking groove 210, so as to be heat-riveted and welded to form a mushroom-shaped locking block 130, and the cross-sectional size of the locking block 130 is larger than the locking groove 210. 0, so that after the locking block 130 is formed, the soft rubber part 20 cannot fall out of the position of the locking block 130. At the same time, the setting height of the locking block 130 enables it to cooperate with the supporting surface 110 to clamp the soft rubber part 20 to lock the soft rubber part 20. The setting of the locking block 130 increases the contact area between the connecting rib 120 and the soft rubber part 20, providing a stronger locking effect, so as to reduce the risk of the soft rubber part 20 falling off during the long-term use of the outer triangle plate, so that it can maintain the sealing and noise reduction effects on the interior of the vehicle for a long time, reduce the maintenance and replacement frequency of the outer triangle plate, and improve the customer's car experience.

[0034] In order to ensure that the setting of the connecting ribs 120 and the locking blocks on the hard rubber part 10 can achieve a stable locking effect on the soft rubber part 20, in some embodiments of the present invention, the setting spacing of the connecting ribs 120 is not greater than 50mm. It should be noted here that the smaller the spacing between adjacent connecting ribs 120, the better. Its limit state is that a single connecting rib 120 fully extends along the edge of the hard rubber part 10, which can achieve complete connection of the soft rubber part 20 at the edge of the hard rubber part 10, but it will lead to an increase in production costs. If the spacing between adjacent connecting ribs 120 is too far, a gap will appear between the connection points of the soft rubber part 20 and the hard rubber part 10, which may cause There is a risk of misalignment and leakage, and according to the design length and design experience of the triangle plate, a spacing of no more than 50 mm can meet the connection strength while reducing the production cost of the triangle plate; a sufficient number of connecting ribs 120 are arranged on the support surface 110 to lock the soft rubber part 20, and at the same time, the spacing between adjacent connecting ribs 120 is preferably equal. The structural form in which the spacing between the connecting ribs 120 is no more than 50 mm can evenly distribute the tensioning force on all the connecting ribs 120, and at the same time avoid the risk of local stress concentration in the soft rubber part 20 due to excessive spacing between the connecting ribs 120, thereby improving the overall structural stability of the outer triangle plate.

[0035] On the basis of the above-mentioned embodiment, the length of each connecting rib 120 in the direction of embedding into the locking groove 210 is not less than 5 mm. It should be noted here that the design thickness of the connecting rib 120 is 1 mm, which is commonly used in rib structures. According to design experience, the length of the connecting rib 120 needs to be not less than 5 times its thickness to meet the strength and form riveted joint requirements. The length design of the connecting rib 120 also ensures that the connecting rib 120 has sufficient length to be inserted into the locking groove 210, and after forming the mushroom-shaped locking block 130, it can still maintain sufficient strength and stability. At the same time, the longer connecting rib 120 can provide a larger riveting area, thereby enhancing the locking force between the connecting rib 120 and the soft rubber part 20.

[0036] It should also be noted that the installation space of the current outer triangle plate is limited, and three buckles are often used to fix it. However, the installation space required for the buckle connection is relatively large, the operation requirements for the operator are high, and the refinement design of the vehicle is poor. Figure 3 and Figure 5In the outer triangular plate provided by the embodiment of the utility model, a hook 30 and a screw column 40 are also provided to protrude toward the same side. The hook 30 and the screw column 40 are assembled toward the inside of the vehicle body for the outer triangular plate to be assembled with the vehicle body. Specifically, the hook 30 is used to be clamped into the edge of the opening position of the door sheet metal 60, that is, the hook 30 passes through the opening position of the door sheet metal 60 as a whole, and then moves vertically downward to be clamped into the edge position to realize the position pre-installation of the outer triangular plate. Correspondingly, the inner side of the hook 30 can be designed with anti-slip patterns to increase the friction between it and the sheet metal to prevent sliding during use; the screw column 40 is used for self-tapping screw assembly. After the hook 30 completes the clamping of the corresponding position, the screw column 40 is aligned with the corresponding mounting hole on the door sheet metal 60, and the outer triangular plate and the door sheet metal 60 are locked by the self-tapping screw. The diameter and length of the screw column 40 are designed according to the specifications of the self-tapping screw to ensure that the self-tapping screw can be smoothly screwed in and provide sufficient fastening force.

[0037] In the above structure, the operator can hold the outer triangle plate, and insert the hook 30 into the opening position of the door sheet metal 60, and move the hook 30 to clamp the edge of the opening position of the door sheet metal 60. At this time, the outer triangle plate can be hung on the door sheet metal 60 and pre-installed. When the hook 30 clamps the door sheet metal 60, the screw column 40 simultaneously reaches the position of the connecting hole on the door sheet metal 60. At this time, the operator can drive the self-tapping screws from inside the car to achieve a fixed connection between the outer triangle plate and the door sheet metal 60. The operation is convenient and has low requirements on the operator's skill level.

[0038] Furthermore, a plurality of hooks 30 can be provided to cooperate with the locking of the pre-installed position of the outer triangular plate. In a preferred embodiment of the utility model, in order to reduce the production cost of the outer triangular plate parts while ensuring the connection effect of the hooks 30, see Figure 3 , Figure 8 and Fig. 9 Two hooks 30 are arranged at intervals, and the two hooks 30 and the screw column 40 are respectively located at the three vertices of the triangular structure. The connection point design of the triangular structure improves the connection stability between the outer triangle plate and the door sheet metal 60, and reduces the risk of shaking and shifting of the outer triangle plate after assembly.

[0039] It should be noted that the design of the hook 30 and the screw column 40 allows the outer triangular plate to be quickly and conveniently assembled to the door sheet metal 60, thereby improving assembly efficiency. The close combination of the hook 30 and the sheet metal and the locking effect of the screw column 40 and the self-tapping screw ensure the fastening reliability of the outer triangular plate during use.

[0040] In order to further optimize the above technical solution, in some embodiments of the present invention, a limiting rib 310 is relatively arranged inside the opening area of ​​the hook 30, so as to clamp the door sheet metal 60 through the limiting rib 310. Specifically, when the hook 30 passes through the opening on the sheet metal and moves vertically downward to clamp into the edge position of the sheet metal, the limiting rib 310 clamps the door sheet metal 60 from both sides to form a structure in which the limiting ribs 310 on both sides clamp the sheet metal. Compared with the conventional clamping method on both sides, the bottom of the hook 30 is pressed against the As for the structure of the sheet metal edge, the hook 30 acts on both sides to reduce the risk of shaking of the outer triangle plate. At the same time, the design structure of the limiting rib 310 ensures that when clamping the door sheet metal 60, the minimum distance between the bottom of the bending position of the hook 30 and the door sheet metal 60 is not less than 1 mm, so as to avoid direct contact between the bottom of the hook 30 and the door sheet metal 60, reduce mechanical wear and vibration noise under vehicle operation conditions, and provide sufficient space so that the hook 30 can adapt to door sheet metals 60 of different thicknesses.

[0041] At the same time, in order to reduce the difficulty of assembling the outer triangular plate and the door sheet metal 60, on the basis of the above embodiment, see Figure 6 The limiting rib 310 on at least one side includes a guide section 3110 structure. The guide section 3110 is specifically a structure that is contracted toward the closed end of the hook 30. The guide section 3110 is used to guide the hook 30 to be inserted into the edge of the opening of the door sheet metal 60 more smoothly during the assembly process. The operator does not need to excessively align the hook 30 with the edge of the opening of the door sheet metal 60 to realize the assembly of the outer triangle plate, thereby improving the assembly accuracy and efficiency of the outer triangle plate.

[0042] Further, see Figure 7 The outer triangular plate provided by the embodiment of the utility model also includes a sponge block 50, which is arranged on the setting plane of the hook 30 and the screw column 40, and the thickness direction of its protrusion is the same as the protrusion direction of the hook 30 and the screw column 40, both facing the inside of the vehicle body. The thickness of the sponge block 50 is sufficient to completely fill the area between the outer triangular plate and the door sheet metal 60 after the outer triangular plate is assembled on the door sheet metal 60, so as to provide a buffering effect at one end, protect the outer triangular plate and the door sheet metal 60, and absorb the vibration and impact generated during the driving of the vehicle, thereby reducing the risk of abnormal noise of the vehicle; it should be noted that the sponge block 50 filling the gap can also improve the sealing between the outer triangular plate and the door sheet metal 60 to prevent the invasion of moisture and dust.

[0043] In addition, considering that in the outer triangular plate provided in the embodiment of the utility model, the hard rubber part 10 and the soft rubber part 20 are formed by two-color injection molding, the connecting rib 120 is designed as a sheet-like plate structure rather than a cylindrical structure, so that the outer triangular plate after molding can be smoothly removed from the two-color mold. At the same time, the molding process of the connecting rib 120 with a sheet-like structure is simpler, thereby reducing the production cost of the outer triangular plate.

[0044] In addition, some embodiments of the utility model also provide a door assembly, which is provided with an outer triangular plate provided by any of the above embodiments at a position connected to the A-pillar of the vehicle. Since the above outer triangular plate has the above technical effects, the door assembly also has the above technical effects, which will not be repeated herein.

[0045] Furthermore, some other embodiments of the utility model also provide a vehicle, which includes at least one door assembly provided by the above embodiment. Of course, it is preferred that both front doors of the vehicle use the door assembly provided by the above embodiment. Since the above door assembly has the above technical effects, the vehicle also has the above technical effects, which will not be repeated herein.
