[0041] In the description of this application, "first feature" and "second feature" may include one or more of the features.

[0042] In the description of this application, "multiple" means two or more.

[0043] In the description of this application, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or the first and second features being in contact through another feature between them.

[0044] In the description of this application, the terms "above," "over," and "on top" for the first feature and the second feature include the first feature being directly above or diagonally above the second feature, or simply indicate that the first feature is at a higher horizontal level than the second feature.

[0045] The following is for reference. Figures 1-10 This application describes the D-pillar assembly 100 and the vehicle 300 according to embodiments thereof.

[0046] The D-pillar assembly 100 according to an embodiment of this application includes a D-pillar 110 and a first reinforcing plate 120.

[0047] refer to Figures 1-2 It is understood that column D 110 has a cavity (not shown in the figure). The cavity can be defined by a beam structure that forms column D 110, that is, the beam can be constructed as a hollow beam with the cavity inside. Of course, the beam can be a one-piece structure or it can be defined by multiple sheet metal enclosures.

[0048] Furthermore, a latch mounting portion 11123 is provided on the side of the D-pillar 110 facing the interior of the vehicle in the Y-direction (i.e., the Y-direction shown in the figure). The latch mounting portion 11123 is used to mount a tailgate latch (not shown in the figure). Here, the vehicle Y-direction is the side direction of the vehicle 300, and the vehicle X-direction is the front-rear direction of the vehicle 300. Accordingly, the latch mounting portion 11123 is formed on the side of the vehicle 300 so that the tailgate latch is adapted to cooperate with the side-opening tailgate (not shown in the figure) to form an opening and closing mechanism.

[0049] In other words, the side-opening tailgate can be hinged to one of the D-pillars of the vehicle body, allowing it to rotate around the D-pillar as a pivot. A lock body is located on the side away from the pivot, and the side-opening tailgate can be flipped relative to the hinge side to switch between the open and closed positions. Therefore, when closing the tailgate, the lock body on the side-opening tailgate engages with a tailgate lock hook located on the side of the other D-pillar assembly 100 facing inwards in the Y-direction of the vehicle, thereby locking the tailgate in the closed position.

[0050] For example, Figure 1 In the illustrated configuration, the latch mounting part 11123 is located on a D-pillar assembly 100, allowing a lock body that engages with the tailgate latch to be installed on the side-opening tailgate, thereby enabling the opening and closing of the side-opening tailgate. It is evident that one side of the side-opening tailgate is connected to the D-pillar assembly 100 via the tailgate latch; therefore, the force borne by the side-opening tailgate is transmitted to the D-pillar assembly 100 through the latch mounting part 11123.

[0051] In order to prevent stress from concentrating on the hook mounting part 11123 when the tailgate lock hook is under force and failing to be transmitted to the D-pillar 110, thereby causing damage to the area or the D-pillar assembly 100, and to meet the strength, durability and other performance requirements of the tailgate lock hook, the D-pillar assembly 100 in this application is also provided with a first reinforcing plate 120 connected to the D-pillar 110.

[0052] Continue to refer to Figure 1 As shown, the illustration is an angle viewing the D-pillar assembly 100 along the Y-direction of the vehicle. This angle allows observation of the D-pillar 110 and the locking hook mounting portion 11123 defined on the D-pillar 110. However, the first reinforcing plate 120 is disposed within the cavity of the D-pillar 110, therefore... Figure 1 The plate structure defining the cavity can be observed, but the cavity and the first reinforcing plate 120 are not visible. For a better explanation, please refer to [reference needed]. Figure 2 The cross-sectional view shown illustrates the first reinforcing plate 120 and the cavity.

[0053] Combination Figures 2-3The first reinforcing plate 120 includes a first plate 121 and a second plate 122. The second plate 122 is bent relative to the first plate 121, and the first reinforcing plate 120 is formed as a bent plate structure. The bent structure of the first plate 121 and the second plate 122 can form a stress transmission path. For example, when the first reinforcing plate 120 is under stress, the stress can be transmitted to the second reinforcing plate 130.

[0054] Furthermore, the first plate 121 is connected to the first side wall of the D-pillar 110, which has a locking hook mounting portion 11123, and the second plate 122 is connected to the second side wall adjacent to the first side wall. The connection area between the first plate 121 and the first side wall at least partially overlaps with the projected outline of the locking hook mounting portion 11123 on the first side wall. For example, the left side of the tailgate of the vehicle 300 can be flipped onto the vehicle body, and the locking hook mounting portion 11123 is provided on the D-pillar assembly 100 on the right side of the vehicle body. The first side wall is the side wall of the D-pillar 100 on the right side of the vehicle body that faces the interior of the vehicle body along the Y direction; the second side wall is the side wall in front of the first side wall or the side wall behind the first side wall.

[0055] Therefore, the first plate 121 and the second plate 122 are connected to the first side wall and the second side wall respectively to form a stress transmission path, so that the load borne by the tailgate can be transmitted to the first plate 121 and then further transmitted to the front side or the rear side of the D-pillar 110 through the second plate 130.

[0056] Specifically, such as Figure 2 As shown, the first sidewall and the second sidewall also form a certain angle, which is consistent with the bending angle of the first plate 121 and the second plate 122, to facilitate connection with the first plate 121 and the second plate 122. Furthermore, the lock hook mounting part 11123 is located on the opposite side of the first sidewall, so when the tailgate lock hook is subjected to force, the stress will be transmitted to the lock hook mounting part 11123. Since the lock hook mounting part 11123 and the first plate 121 are positioned opposite each other on the first sidewall, their projections on the first sidewall coincide. This means that when the lock hook is subjected to force, the stress can be directly applied to the area on the first plate 121 corresponding to the lock hook mounting part 11123, thus fully transmitting the stress.

[0057] Furthermore, through the bonding of the first sidewall with the first plate 121 and the bonding of the second plate 122 with the second sidewall, the stress exerted by the first sidewall on the first plate 121 can continue to be transmitted along the overall structure formed by the first plate 121 and the second plate 122 to the second sidewall. In turn, the stress is fully transmitted and distributed in various areas of the D-pillar 110 through the second sidewall, avoiding stress concentration in the locking hook mounting part 11123.

[0058] In other words, when the lock hook is subjected to force, the stress is first transmitted to the lock hook mounting part 11123, which is used to mount the lock hook. Since the lock hook mounting part 11123 is on the first side wall, the first side wall continues to transmit the stress to the first plate 121, and then through the stress transmission path formed by the first plate 121 and the second plate 122, the stress is transmitted to the second side wall, and further to other parts of the D-pillar 110. This ensures that the stress transmission path on the D-pillar 110 after the tailgate lock hook is subjected to force is continuous and without breaks, thereby evenly distributing the stress in every area of ​​the transmission path and reducing the possibility of stress concentration in the lock hook mounting part 11123, which could lead to its damage.

[0059] It is worth noting that, based on the fact that the first reinforcing plate 120 can connect to the cavity within the D-pillar 110 and that stress can be uniformly transmitted, the structure of the D-pillar assembly 100 can differ in different examples. For example, the aforementioned first sidewall and second sidewall can be constructed on different components within the D-pillar 110, or they can be constructed on the same component within the D-pillar 110. For example, the first reinforcing plate 120 can also be provided with a locking hook mounting portion 11123. Furthermore, the first reinforcing plate 120 can also be configured as a structure with more plates, etc., details of which will not be elaborated here.

[0060] According to the D-pillar assembly 100 of this application embodiment, a first reinforcing plate 120 is provided in the cavity of the D-pillar 110. The stress of the lock hook mounting portion 11123 is transmitted through the first plate 121 of the first reinforcing plate 120, and then transmitted to other areas of the D-pillar 110 through the second plate 122 and the cavity connected thereto, so as to form a continuous stress transmission path. Through this transmission path, the stress at the location where the tailgate lock hook is installed on the D-pillar 110 is dispersed to prevent damage and avoid a series of problems such as the tailgate being unable to open and close normally and the body sheet metal cracking due to rear collision, thereby meeting the performance requirements such as strength and durability.

[0061] In some examples, reference Figures 1-5 As shown, the D-pillar 110 includes an inner D-pillar panel 111 and a reinforcing D-pillar panel 112. The inner D-pillar panel 111 and the reinforcing D-pillar panel 112 participate in defining the cavity. In other words, the reinforcing D-pillar panel 112 and the inner D-pillar panel 111, as part of the sheet metal of the D-pillar, participate in defining the cavity formed inside the D-pillar 110.

[0062] In this example, the inner panel 111 of the D-pillar and the reinforcing plate 112 of the D-pillar are spaced apart, and the first reinforcing plate 120 is disposed between the inner panel 111 of the D-pillar and the reinforcing plate 112 of the D-pillar.

[0063] For details, please refer to Figure 2 as well as Figure 4 , Figure 5It is understood that the inner panel 111 of the D-pillar includes a third panel 11121 and a fourth panel 11122 with an included angle, and the included angle between the third panel 11121 and the fourth panel 11122 is consistent with the included angle formed by the bending between the first panel 121 and the second panel 122. The third panel 11121 defines a first sidewall on the side facing the D-pillar reinforcing panel 112, and the fourth panel 11122 defines a second sidewall on the side facing the D-pillar reinforcing panel 112. Thus, the first panel 121 is fitted with the third panel 11121, and the second panel 122 is fitted with the fourth panel 11122.

[0064] Continue to combine Figure 2 and Figure 4 To understand this, the locking hook mounting portion 11123 is formed on the side of the third plate 11121 away from the fourth plate 11122. Correspondingly, the side of the third plate 11121 closest to the fourth plate 11122 is a first sidewall and is used to fit against the first plate 121. Furthermore, the side of the fourth plate 11122 closest to the third plate 11121 is a second sidewall and is used to fit against the second plate 122.

[0065] Therefore, when the tailgate latch is subjected to external force, the stress is first transmitted through the latch mounting part 11123 to the third plate 11121 of the inner panel 111 of the D-pillar. Since the third plate 11121 is fitted with the first plate 121 of the first reinforcing plate 120, this stress is then transmitted to the first reinforcing plate 120. The first reinforcing plate 120 uses the bending structure formed by the first plate 121 and the second plate 122 as the stress transmission path, guiding the stress from the third plate 11121 to the fourth plate 11122, and further transmitting it along the structure around the cavity of the D-pillar 110.

[0066] To improve the continuity of stress transfer and enhance the structural strength of the D-pillar assembly 100, reference is made. Figures 2-6 It is understood that in some embodiments, the D-pillar assembly 100 may also be provided with a second reinforcing plate 130. The second reinforcing plate 130 is also disposed in the cavity, and the second reinforcing plate 130 is connected to the second plate 122, with one end of the second reinforcing plate 130 facing the D-pillar reinforcing plate 112 connected to the D-pillar reinforcing plate 112.

[0067] Therefore, the stress of the second plate 122 can continue to be transmitted to the second reinforcing plate 130, and the second reinforcing plate 130 is connected to the D-pillar reinforcing plate 112 at one end, so that the stress can continue to be transmitted to the D-pillar reinforcing plate 112, and the second reinforcing plate 130 can serve as a stress transmission path to disperse the stress generated by the load borne by the lock hook mounting part 11123.

[0068] And, as Figure 2As shown, the second reinforcing plate 120 and the first reinforcing plate 110 are disposed together in the cavity to form a cavity structure with the first plate 121 and the second plate 122. The first reinforcing plate 110 and the second reinforcing plate 120 are connected to other sheet metal parts of the D-pillar 110 in the cavity, and can serve as a reinforcing structure for the D-pillar 110 to improve the overall structural strength of the D-pillar 110.

[0069] In different examples, the stress transmission paths formed by the first reinforcing plate 120 and the second reinforcing plate 130 may be slightly different.

[0070] For example, in some examples, the end of the second reinforcing plate 130 facing the first plate 121 pushes against the first plate 121 to form a stress transfer node. In other words, when the tailgate latch is subjected to stress and it is transferred to the first plate 121 through the third plate 11121, this stress will not only continue to be transferred to the second plate 122 through the bending structure of the first plate 121 and the second plate 122, but also, due to the pushing action of the second reinforcing plate 130 against the first plate 121, a portion of the stress will be directly transferred to the second reinforcing plate 130 along this pushing interface, thus forming a new stress transfer path.

[0071] In other examples, refer to Figure 2 As shown, the end of the second reinforcing plate 130 facing the first plate 121 is spaced apart from the first plate 121; the end described here is... Figure 2 The second reinforcing plate 130 is located along the Y direction and away from the end of the first reinforcing plate 120. The edge of the second reinforcing plate 130 facing the first plate 121 is connected to the edge of the first plate 121 facing the second reinforcing plate 130. Furthermore, the edge of the second reinforcing plate 130 facing the third plate 11121 is connected to the edge of the third plate 11121 facing the second reinforcing plate 130. The connection method can be any method such as screwing or welding.

[0072] In this example, the second reinforcing plate 130 is connected to the first plate 121 and the third plate 11121, and one edge of the plate is connected to the D-pillar reinforcing plate 112. Therefore, a complete and continuous stress transmission path can be formed to transmit the stress of the locking hook mounting part 11123 to the third plate 11121 and the D-pillar reinforcing plate 112.

[0073] Understandably, the second reinforcing plate 130 connects the first reinforcing plate 120 and the D-pillar reinforcing plate 112, thus providing an additional mechanical transmission path for stress, allowing the first reinforcing plate 120 to disperse stress through the cavity within the D-pillar. Therefore, the second reinforcing plate 130 further optimizes the stress transmission path, enabling the stress of the locking hook mounting portion 11123 to be evenly transmitted to each sheet metal element within the cavity, effectively preventing damage caused by stress concentration. Furthermore, the first reinforcing plate 110 and the second reinforcing plate 120, positioned within the cavity, further define the cavity, forming a reinforcing structure within the cavity of the D-pillar 110, thereby further improving the overall structural strength of the D-pillar 110.

[0074] Next, refer to Figure 2 as well as Figure 6 We will continue to provide a detailed description of the second reinforcing plate 130.

[0075] In some examples, such as Figure 6 As shown, the second reinforcing plate 130 bends and extends a first flange 131 toward one edge of the second sidewall, and the first flange 131 is connected to the second plate 122 and the second sidewall.

[0076] Specifically, the first flange 131 is disposed on the edge of one end of the second reinforcing plate 130 along the X direction in the figure, and the first flange 131 extends upward along the Z direction in the figure. The first flange 131 is provided with three bolt holes, and the fourth plate 11122 is also provided with three bolt holes, so as to connect the fourth plate 11122 and the first flange 131 by bolts 140.

[0077] Here, combined Figure 2 Understand that the three bolts 140 shown in the diagram are defined as bolt 141, bolt 142, and bolt 143. In the example, the length of the second plate 122 is H. Bolt 141 passes through the fourth plate 11122, the second plate 122, and the first flange 131 in sequence to connect the inner plate 111 of the D-pillar, the first reinforcing plate 120, and the second reinforcing plate 130. Bolt 142 and bolt 143 pass through the fourth plate 11122 and the first flange 131 in sequence to connect the second reinforcing plate 130 to the inner plate 111 of the D-pillar.

[0078] Therefore, the first flange 131 connects the second reinforcing plate 130 with the first reinforcing plate 120 and the inner plate of the D-pillar 111, forming a stress transfer path between the first reinforcing plate 120 and the second reinforcing plate 130, and between the inner plate of the D-pillar 111 and the second reinforcing plate 130.

[0079] Understandably, due to the connection structure between the first flange 131 and the first plate and the inner D-pillar plate 111, it is suitable for transferring the stress borne on the first plate 121 to the second reinforcing plate 130, and also suitable for transferring the stress of the inner D-pillar plate 111 to the second reinforcing plate 130, thereby dispersing the stress to other areas of the D-pillar. This optimizes the mechanical transmission path and prevents stress concentration in the locking hook mounting portion 11123. On the other hand, the first flange 131 is connected to the first plate 121 and the inner D-pillar plate 111 by bolts 140 to form a close fit between the first flange 131 and the first plate 121, and between the first flange 131 and the inner D-pillar plate 111, thereby improving the overall structural strength of the structure formed by the connection between the second reinforcing plate 130 and the first reinforcing plate 120, and between the second reinforcing plate 130 and the inner D-pillar plate 111, and thus improving the overall structural strength of the D-pillar.

[0080] In some examples, reference Figure 6 The second reinforcing plate 130 bends and extends a second flange 132 toward one side edge of the D-pillar reinforcing plate 112, and the second flange 132 is connected to the D-pillar reinforcing plate 112.

[0081] Specifically, in combination Figure 2 Understandably, the second flange 132 is disposed on the edge of one end of the second reinforcing plate 130 in the Y direction shown in the figure, and extends downwardly folded along the Z direction shown in the figure. The second flange 132 is adapted to fit against the side wall of the D-pillar reinforcing plate 112 facing the cavity to form a stress transmission path.

[0082] Understandably, the second flange 132 connects the second reinforcing plate 130 to the D-pillar reinforcing plate 112, which can transfer the stress received by the second reinforcing plate 130 to the D-pillar reinforcing plate 112, thereby dispersing the stress onto the D-pillar reinforcing plate 112. The stress is further dispersed through the D-pillar reinforcing plate 112, so that the stress acting on the lock hook mounting part 11123 is fully dispersed in other areas of the D-pillar 110.

[0083] In some examples, reference Figure 2 and Figure 7 As shown, the D-pillar assembly 100 also includes a taillight mounting plate 150 for mounting the taillight assembly. The D-pillar 110 is connected to the taillight mounting plate 150 on the side of the vehicle away from the interior in the X direction.

[0084] refer to Figure 2 As shown, one side of the taillight mounting plate 150 is used to form an area for mounting the taillights, and the opposite side is connected to the D-pillar 110. For example, the side of the D-pillar reinforcement plate 112 away from the inner D-pillar panel 111 is connected to the taillight mounting plate 150, thereby forming a stress transfer path between the taillight mounting plate 150 and the D-pillar reinforcement plate 112.

[0085] It is understandable that the connection between the taillight mounting plate 150 and the D-pillar 110 allows the stress on the D-pillar 110 to be further transferred to the taillight mounting plate 150 through the connection structure, thereby dispersing the stress. Furthermore, since the taillight mounting plate 150 has a concave-convex structure, the cavity formed after the taillight mounting plate 150 and the D-pillar 110 are connected can also enhance the structural strength of the connection point.

[0086] In some examples, combined Figures 2-6 As shown, the second reinforcing plate 130 bends and extends a third flange 133 towards one side edge of the taillight mounting plate 150, and the third flange 133 is connected to the taillight mounting plate 150.

[0087] Specifically, the third flange 133 is located on one side edge in the X direction of the figure, and extends downward along the Z direction of the figure. The third flange 133 is adapted to fit between the taillight mounting plate 150 and the taillight mounting plate 150.

[0088] Understandably, the third flange 133 connects the second reinforcing plate 130 to the taillight mounting plate 150, allowing the second reinforcing plate 130 to transfer stress to the taillight mounting plate 150, thereby achieving stress dispersion. Furthermore, in this example, stress is directly transferred to the taillight mounting plate 150 through the second flange 132. Therefore, the second reinforcing plate 130, acting as the stress transfer path between the second plate 122 and the taillight mounting plate 150, effectively transfers stress.

[0089] Of course, in conjunction with the above exemplary cases, the second reinforcing plate 130 can also be constructed as follows: Figure 6 As shown, a first flange 131, a second flange 132, and a third flange 133 are set simultaneously. The specific principle will not be elaborated here.

[0090] Furthermore, the D-pillar 110 is typically composed of multiple stacked sheet metal panels, thus being spaced apart to define a cavity for housing the first reinforcing plate 120 and the second reinforcing plate 130. (This is combined with...) Figures 1-10 The structure of column D110 is described exemplarily.

[0091] Furthermore, it is worth noting that the subsequent detailed description of the structure of the D-pillar 110 is merely an illustrative example, and the specific sheet metal structure may differ in different vehicle models.

[0092] In some embodiments, the D-pillar 110 also includes an outer D-pillar panel 113, and the outer D-pillar panel 113 and the inner D-pillar panel 111 together define a cavity.

[0093] For details, please refer to Figure 5 as well as Figures 8-10As shown, the D-pillar 110 includes an outer D-pillar panel 113, a reinforcing D-pillar panel 112, and an inner D-pillar panel 111 arranged sequentially along the X direction of the vehicle. A first reinforcing plate 120 and a second reinforcing plate 130 from the aforementioned embodiment are disposed between the inner D-pillar panel 111 and the reinforcing D-pillar panel 112.

[0094] refer to Figure 5 As shown, the D-pillar reinforcement plate 112 includes an upper D-pillar reinforcement plate 1121 and a lower D-pillar reinforcement plate 1122, which mate along the Z direction shown in the figure to form the D-pillar reinforcement plate 112. (Reference) Figure 8 As shown, the outer panel 113 of the D-pillar includes an upper plate 1131 and a lower plate 1132. The upper plate 1131 and the lower plate 1132 of the D-pillar fit together along the Z direction as shown in the figure to form the outer panel 113 of the D-pillar. (Reference) Figure 9 As shown, the inner panel 111 of the D-pillar includes an upper plate 1111 and a lower plate 1112 of the D-pillar. The upper plate 1111 and the lower plate 1112 of the D-pillar are fitted together along the Z direction shown in the figure to form the inner panel 111 of the D-pillar.

[0095] The outer D-pillar panel 113, the reinforcing plate 112, and the inner D-pillar panel 111 are stacked along the X direction to jointly define a cavity. A first reinforcing plate 120 and a second reinforcing plate 130 are disposed between the lower inner D-pillar panel 1112 and the lower reinforcing plate 1122, and are combined with… Figure 1 As shown, the lower plate 1112 of the inner panel of the D-pillar is provided with a locking hook mounting part 11123 on the plate surface in the Y direction. The lower reinforcing plate 1122 of the D-pillar includes a fifth plate 11221 and a sixth plate 11222 with an angle, and the third plate 11121, the fourth plate 11122, the fifth plate 11221 and the sixth plate 11222 surround the first reinforcing plate 120 and the second reinforcing plate 130 within the surrounded space.

[0096] The structure of the D-pillar assembly after assembly (100) can be referenced. Figure 10 Please understand as shown. Figure 10 The inner panel 111 of the D-pillar and the reinforcing plate 112 of the D-pillar are not visible. Furthermore, refer to... Figure 10 As shown, the D-pillar assembly 100 is connected to the side panel 200 and the taillight mounting plate 150 to form the rear area of ​​the vehicle 300.

[0097] Understandably, the D-pillar assembly 100 possesses good structural strength and provides sufficient strength and durability for the latch mounting portion 11123. This prevents damage to the latch mounting portion 11123 due to prolonged opening, which could lead to tailgate latch misalignment, difficulty in opening and closing the tailgate properly, and poor sealing after closing, resulting in water leakage. Furthermore, in the event of a rear-end collision, it can transfer the stress acting on the latch mounting portion 11123 to various parts of the D-pillar 110, thereby reducing the risk of sheet metal cracking.

[0098] According to any of the above embodiments, two or more connection points can be constructed on the second plate 122 to connect the second plate 122 and the second sidewall. For example, double rows of weld points can be arranged between them to enable uniform stress transfer between the second plate 122 and the second sidewall. Similarly, multiple connection points can also be provided between the first plate 121 and the first sidewall; the specific principle will not be elaborated further.

[0099] The vehicle 300 according to an embodiment of this application includes the D-pillar assembly 100 in the above embodiment.

[0100] For example, vehicle 300 can be constructed with a non-load-bearing body and a side-opening tailgate. Vehicle 300 includes two D-pillar assemblies 100 symmetrically arranged on both sides of the body and a tailgate; these are here defined as the first D-pillar and the second D-pillar. The first D-pillar is... Figure 10 The first D-pillar is constructed as the D-pillar assembly 100 in the aforementioned embodiment; the second D-pillar is not shown in the figure and can be constructed as any D-pillar assembly 100.

[0101] Specifically, one side of the tailgate is rotatably connected to the second D-pillar, and the other side is equipped with a tailgate lock body. The tailgate lock body is adapted to engage with the lock hook on the first D-pillar so that the tailgate can be opened and closed laterally at the rear of the vehicle 300.
