Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a vehicle body structure and a vehicle. Background Technology

[0002] The vehicle body structure in the related technology includes multiple connected sheet metal parts, and the vehicle body structure has cavities. Since the design of multiple connected sheet metal parts makes it difficult to completely seal the cavities, when the exterior of the vehicle body structure comes into contact with liquid, the liquid can easily enter the cavities from the outside. Therefore, a large amount of liquid can easily accumulate in the cavities of the vehicle body structure. Utility Model Content

[0003] In view of this, this application provides a vehicle body structure and vehicle that can better improve the problem of excessive liquid accumulation in the cavities of the vehicle body structure.

[0004] In a first aspect, this application provides a vehicle body structure, which includes a tailgate frame assembly and a rear floor. The tailgate frame assembly includes a rear pillar assembly, the rear pillar assembly is provided with a rear pillar drain structure, the rear floor is provided with a first rear floor collection structure, the bottom of the first rear floor collection structure is provided with a first rear floor drain structure, the position height of the rear pillar drain structure is greater than the position height of the first rear floor collection structure, and the projection of the rear pillar drain outlet of the rear pillar drain structure along the height direction of the vehicle body structure is on the first rear floor collection structure.

[0005] The top of the rear pillar assembly is located on top of the tailgate frame assembly, and is relatively close to the roof assembly of the vehicle body structure. The top of the tailgate frame assembly and the roof assembly of the vehicle body structure are likely to come into contact with a significant amount of liquid (rainwater or sprayed cleaning agents). Consequently, the top of the rear pillar assembly is also likely to come into contact with a significant amount of liquid, making it highly probable that liquid will first enter the rear pillar cavity of the rear pillar assembly. Therefore, in this application, a rear pillar drainage structure is provided in the rear pillar assembly. This drainage structure drains the liquid located in the rear pillar cavity to a first rear floor drainage structure located below. The liquid in the first rear floor drainage structure can then flow to the first rear floor drainage structure, which can then discharge the liquid to the outside of the vehicle body structure. With this configuration, liquid is less likely to accumulate in the rear pillar cavity, reducing the likelihood of liquid remaining in the rear pillar cavity for extended periods. This reduces the likelihood of electrical components in the rear pillar cavity malfunctioning or experiencing safety issues due to contact with liquid, and also reduces the likelihood of rust and corrosion on the inner surface of the rear pillar assembly.

[0006] Optionally, the first rear floor liquid collection structure includes a first liquid guiding slope, and the first rear floor liquid drainage structure is disposed at the bottom of the first liquid guiding slope. The first liquid guiding slope has a set inclination angle α, which satisfies 3°≤α≤20°.

[0007] Optionally, the vehicle body structure also includes a side outer panel, the bottom of the first liquid guiding slope is connected to the side outer panel, and the first rear floor drainage structure includes a first drainage rib, the first drainage rib and the side outer panel enclose to form a first drainage cavity, the first drainage cavity being connected to the outside of the vehicle body structure.

[0008] Optionally, the inner wall surface of the rear column assembly includes a rear column liquid guiding slope, and the rear column liquid drainage inlet of the rear column drainage structure is located at the bottom of the rear column liquid guiding slope.

[0009] Optionally, the tailgate frame assembly includes a rear enclosure assembly connected to the rear pillar assembly. The rear enclosure assembly is provided with a rear drainage structure, and the rear floor is provided with a second rear floor collection structure. The bottom of the second rear floor collection structure is provided with a second rear floor drainage structure. The height of the rear enclosure drainage structure is greater than the height of the second rear floor collection structure. The projection of the rear enclosure drainage outlet of the rear enclosure drainage structure along the height direction is onto the second rear floor collection structure and / or the second rear floor drainage structure.

[0010] Optionally, the second rear floor liquid collection structure includes at least two stepped surfaces, and the second rear floor liquid drainage structure is disposed on the lowest stepped surface.

[0011] Optionally, the lowest step surface includes a second liquid guiding slope, and the second rear floor drainage structure is located at the bottom of the second liquid guiding slope. The second liquid guiding slope has a set inclination angle β, which satisfies 3°≤β≤7°.

[0012] Optionally, the rear enclosure assembly includes a rear outer panel, the bottom of the second liquid guiding ramp is connected to the rear outer panel, and the second rear floor drainage structure includes a second drainage rib, the second drainage rib and the rear outer panel enclose to form a second drainage cavity, the second drainage cavity being connected to the outside of the vehicle body structure.

[0013] Optionally, the inner wall surface of the rear enclosure assembly includes a rear enclosure liquid guiding slope, and the rear enclosure liquid drainage inlet of the rear enclosure liquid drainage structure is located at the bottom of the rear enclosure liquid guiding slope.

[0014] Secondly, this application provides a vehicle that includes the body structure described above, and correspondingly, the vehicle also includes the technical effects of the body structure described above, which will not be repeated here.

[0076] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0077] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0078] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0079] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0080] In the accompanying diagrams, directions X, Y, and Z are perpendicular to each other. Direction X represents the direction from the rear of the vehicle structure to the front of the vehicle structure, and direction Z represents the direction from the top of the vehicle structure to the bottom of the vehicle structure.

[0081] Firstly, this application provides a vehicle body structure, please refer to... Figure 1 As shown, the vehicle body structure includes a tailgate frame assembly 1 and a rear floor 2. The tailgate frame assembly 1 is located at the rear of the vehicle body; specifically, it is located on the side of the passenger compartment opposite to the driver's side. The tailgate frame assembly 1 has an opening that engages with the vehicle's tailgate. In some cases, the tailgate can close to the opening; in other cases, the tailgate can move relative to the tailgate frame assembly 1 to open the opening, allowing the passenger compartment space to communicate with the space outside the rear of the vehicle.

[0082] Please refer to Figure 1 As shown, the lower part of the tailgate frame assembly 1 is connected to the rear floor 2, which can be used to install seats and can also carry items. Therefore, when the opening of the tailgate frame assembly 1 is open, the user can place or retrieve items on the rear floor 2 through the opening of the tailgate frame assembly 1 on the rear side of the vehicle structure. Of course, the user can also get on or off the vehicle through the opening of the tailgate frame assembly 1.

[0083] Generally, the tailgate frame assembly 1 includes multiple connected sheet metal parts that enclose a cavity. The cavity inside the tailgate frame assembly 1 can be used to house electrical wiring, electrical components, and other electrical devices required by the vehicle, and the height of the cavity inside the tailgate frame assembly 1 is greater than the height of the rear floor 2.

[0084] In the tailgate frame assembly 1, the connection between at least two sheet metal parts can be sealed by welding, bonding or using a sealing strip, but it is impossible to achieve a 100% sealing effect. When the tailgate frame assembly 1 is exposed to rain, water, cleaning agents or snow, liquids (rain, dew, water or cleaning agents) may enter the cavity inside the tailgate frame assembly 1.

[0085] To drain the liquid from the cavity inside the tailgate frame assembly 1, some embodiments of the vehicle body structure in this application may include a structure with a drainage function, as detailed below.

[0086] Please refer to Figure 1 As shown, the tailgate frame assembly 1 includes a rear pillar assembly 11, the rear pillar assembly 11 is provided with a rear pillar drainage structure 12, and the rear floor 2 is provided with a first rear floor collection structure 21. Please refer to... Figure 2 As shown, a first rear floor drainage structure 22 is provided at the bottom of the first rear floor liquid collection structure 21, and the height of the rear column drainage structure 12 is greater than the height of the first rear floor liquid collection structure 21. Please refer to... Figure 2 As shown, the projection of the rear pillar drain outlet 121 of the rear pillar drain structure 12 onto the first rear floor liquid collection structure 21 along the height direction of the vehicle body structure (the direction parallel to direction Z).

[0087] Please refer to Figure 1 As shown, the top of the rear pillar assembly 11 is located at the top of the tailgate frame assembly 1, and the top of the rear pillar assembly 11 is relatively close to the roof assembly of the vehicle body structure. The top of the tailgate frame assembly 1 and the roof assembly of the vehicle body structure may easily come into contact with a large amount of liquid (falling rainwater or sprayed cleaning agents). Correspondingly, the top of the rear pillar assembly 11 is also likely to come into contact with a large amount of liquid, making it more likely that liquid will first enter the rear pillar cavity of the rear pillar assembly 11. Therefore, in some embodiments of this application, a rear pillar drainage structure 12 is provided in the rear pillar assembly 11. The rear pillar drainage structure 12 can drain the liquid located in the rear pillar cavity to the first rear floor collection structure 21 located below. The liquid located in the first rear floor collection structure 21 can flow to the first rear floor drainage structure 22, which can discharge the liquid to the outside of the vehicle body structure. With this configuration, liquid is less likely to accumulate in the rear column cavity, reducing the likelihood of liquid remaining in the rear column cavity for an extended period. This reduces the likelihood of electrical components in the rear column cavity malfunctioning or experiencing safety issues due to contact with liquid, and also reduces the likelihood of rust or corrosion on the inner surface of the rear column assembly 11.

[0088] Where the vehicle type includes a commercial vehicle or van, the vehicle may include an A-pillar assembly, a B-pillar assembly, a C-pillar assembly, and a D-pillar assembly, and the rear pillar assembly 11 may be referred to as the D-pillar assembly. Where the vehicle type includes a sedan (hatchback or sedan model) or a sport utility vehicle (SUV), the vehicle may include an A-pillar assembly, a B-pillar assembly, and a C-pillar assembly, and the rear pillar assembly 11 may be referred to as the C-pillar assembly. The following content mainly describes the rear pillar assembly 11 using the D-pillar assembly as an example.

[0089] In addition, the rear column drainage structure 12 can be set at the bottom of the rear column assembly 11 so that the liquid in the rear column cavity can be effectively discharged by the rear column drainage structure 12 after flowing downward to the bottom.

[0090] Please refer to Figure 2 As shown, when the amount of liquid discharged from the rear pillar drainage structure 12 is relatively large, or when the vehicle is in a state of acceleration, deceleration or steering, the liquid discharged from the rear pillar drainage structure 12 can be better confined or collected in the first rear floor liquid collection structure 21 located below after falling into it. This reduces the possibility of liquid flowing randomly on the rear floor 2 and accumulating on the rear floor 2, reduces the possibility of mold or odor problems on the rear floor 2, and reduces the possibility of electrical components installed on the rear floor 2 coming into contact with the liquid and malfunctioning or causing safety problems.

[0091] In some embodiments, please refer to Figure 2 As shown, the first rear floor liquid collection structure 21 may include a first liquid guiding slope 211, and the first rear floor liquid drainage structure 22 is disposed at the bottom of the first liquid guiding slope 211. The first liquid guiding slope 211 has a set inclination angle α (e.g., Figure 2 The tilt angles α1 and α2 shown satisfy 3° ≤ α ≤ 20°. Figure 2 The dotted line O in the diagram represents a horizontal line. The dotted line O is perpendicular to the direction Z. The dotted line O can be used as a reference to measure the magnitude of the inclination angle α of the first fluid guiding slope 211.

[0092] In some embodiments, please refer to Figure 2 As shown, when liquid falls from the rear pillar drainage structure 12 onto the first liquid guiding ramp 211, the liquid can flow along the first liquid guiding ramp 211 towards the first rear floor drainage structure 22 under the action of gravity, and the liquid can then be discharged from the first rear floor drainage structure 22 to the outside of the vehicle structure. With this configuration, the first liquid guiding ramp 211 can quickly guide the liquid to the first rear floor drainage structure 22, allowing the liquid to be quickly discharged from the first rear floor drainage structure 22 to the outside of the vehicle structure, thus possessing the advantage of high drainage efficiency.

[0093] The tilt angle α can be 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19° or 20°.

[0094] In addition, when the tilt angle α is in the range of 3° to 20°, the first liquid guiding slope 211 can significantly increase the flow velocity of the liquid towards the first rear floor drainage structure 22, and the size of the first liquid guiding slope 211 in the Z direction will not be too large, that is, the first liquid guiding slope 211 is not easy to interfere with the structure below.

[0095] In some embodiments, the first fluid guiding slope 211 may include at least two slopes, please refer to Figure 2 As shown, the first liquid guiding slope 211 may include a first-stage liquid guiding slope 211a and a second-stage liquid guiding slope 211b, with the first-stage liquid guiding slope 211a being at a higher position than the second-stage liquid guiding slope 211b. The first-stage liquid guiding slope 211a may be located directly below the rear column drainage structure 12 or the rear column drainage outlet 121, and the first rear floor drainage structure 22 may be located at the bottom of the second-stage liquid guiding slope 211b. Liquid discharged from the rear column drainage outlet 121 may fall onto the first-stage liquid guiding slope 211a, and the liquid falling onto the first-stage liquid guiding slope 211a may flow towards the second-stage liquid guiding slope 211b under the action of gravity. The liquid flowing to the second-stage liquid guiding slope 211b may then flow towards the first rear floor drainage structure 22. The inclination angle α2 of the second-stage liquid-conducting slope 211b can be greater than the inclination angle α1 of the first-stage liquid-conducting slope 211a. During the process of liquid flowing from the first-stage liquid-conducting slope 211a to the second-stage liquid-conducting slope 211b, the liquid flow velocity increases, thus possessing the advantage of higher drainage efficiency. It should be noted that both the inclination angles α1 and α2 are within the range of 3° to 20°.

[0096] In other embodiments (not shown in the figure), the inclination angle of the first-stage liquid guiding slope can be greater than that of the second-stage liquid guiding slope. When the liquid falls from the discharge outlet of the rear column onto the first-stage liquid guiding slope, the liquid is less likely to be bounced off the first-stage liquid guiding slope to other parts of the rear floor, so that the liquid can be better collected in the first rear floor liquid collection structure.

[0097] In other embodiments (not shown in the figures), the first liquid guiding slope may include a single-stage slope, i.e., the inclination angle of the first liquid guiding slope is fixed.

[0098] In other embodiments (not shown in the figure), the first rear floor liquid collection structure may include a liquid collection tank located directly below the rear column liquid drainage structure or the rear column liquid drainage outlet. The first rear floor liquid drainage structure is disposed at the bottom of the liquid collection tank. In this configuration, the liquid collection tank also has a similar technical effect of restricting liquid flow as the first liquid guiding slope, which will not be described in detail here.

[0099] In some embodiments, please refer to Figures 1-2 As shown, the vehicle body structure may also include a side outer panel 3, with the bottom of the first liquid guiding ramp 211 connected to the side outer panel 3. Please refer to [reference needed]. Figures 2-3 As shown, the first rear floor drainage structure 22 may include a first drainage rib 221, and the first drainage rib 221 and the side outer plate 3 can be enclosed to form a shape as shown. Figure 3 The first drain chamber 221a shown is connected to the outside of the vehicle body structure. In this configuration, the liquid located on the first liquid guiding ramp 211 can flow to the outside of the vehicle body structure via the first drain chamber 221a.

[0100] in, Figure 3 The view shown is from the bottom and outside of the vehicle body structure, observing the first drain rib 221. Figure 3 The protrusion direction of the first drainage rib 221 shown can be the opposite of the Y direction. In other words, the protrusion direction of the first drainage rib 221 is away from the side outer plate 3, so that there can be a first drainage cavity 221a between the first drainage rib 221 and the side outer plate 3. Figure 3 The first fluid-conducting slope 211 shown is observed under perspective.

[0101] Of course, you can also Figure 4 The first rib 221 is observed from the shown perspective. Figure 4 The view shown is from inside the vehicle body structure.

[0102] In some embodiments, please refer to Figure 3 As shown, the first rear floor liquid collection structure 21 is also provided with a first extension 212. The first extension 212 extends downward from the bottom of the first liquid guiding slope 211, and the first extension 212 is attached to the side outer plate 3. The first drainage rib 221 protrudes relative to the first extension 212 in a direction away from the side outer plate 3.

[0103] In some embodiments, the first drainage rib 221, the first drainage ramp 211, and the first extension 212 can be integrally formed, all serving as part of the rear floor 2 and belonging to the same sheet metal part.

[0104] In some embodiments, please refer to Figure 5 As shown, the bottom of the side panel 3 may include a side flange 31, and the side flange 31 may be connected to... Figure 3 The first drainage rib 221 in the middle surrounds and forms the first drainage cavity 221a, and the side flange 31 can be connected with... Figure 3 The first extension 212 is fitted and connected.

[0105] In other embodiments (not shown in the figures), the first drainage cavity may also be formed independently of the side panel enclosure, and the first drainage cavity may be mainly formed by the first rear floor drainage structure or the first drainage rib.

[0106] In other embodiments (not shown in the figures), the first rear floor drainage structure can also be a one-way drainage valve, which is installed on and passes through the first rear floor collection structure. Liquid can flow from the first rear floor collection structure to the outside of the vehicle body structure via the one-way drainage valve. Liquid located outside the vehicle body structure cannot flow to the first rear floor collection structure via the one-way drainage valve, which can reduce the possibility of liquid outside the vehicle body structure entering the interior space of the vehicle body structure.

[0107] In some embodiments, please refer to Figure 6 As shown, the inner wall surface of the rear column assembly 11 includes a rear column liquid guiding slope 11b, and the rear column drain inlet 122 of the rear column drain structure 12 is located at the bottom of the rear column liquid guiding slope 11b. Under the action of gravity, the liquid in the rear column cavity 11a can accumulate on the rear column liquid guiding slope 11b, and the liquid accumulated on the rear column liquid guiding slope 11b will flow towards the rear column drain inlet 122 so that the liquid can be discharged from the rear column drain outlet 121. With this configuration, liquid is less likely to accumulate in the rear column cavity 11a, reducing the possibility of liquid remaining in the rear column cavity 11a for a long time, reducing the possibility of electrical components in the rear column cavity 11a malfunctioning or experiencing safety issues due to contact with liquid, and reducing the possibility of rust and corrosion on the inner surface of the rear column assembly 11.

[0108] Among them, the inner wall surface of the rear column assembly 11 and the liquid guiding slope 11b of the rear column are structural surfaces facing the rear column cavity 11a.

[0109] In addition, the bottom of the inner wall of the rear column assembly 11 may include two oppositely arranged rear column liquid guiding slopes 11b, and a rear column drain inlet 122 may be provided between the bottoms of the two oppositely arranged rear column liquid guiding slopes 11b.

[0110] In some embodiments, one of the structural components of the rear pillar assembly 11 can be integrally formed with the rear pillar drainage structure 12, that is, one of the structural components of the rear pillar assembly 11 and the rear pillar drainage structure 12 can be part of the same sheet metal part. The rear pillar drainage structure 12 can include a rib structure, and the rib structure partially surrounds and forms a drainage cavity that communicates with the rear pillar cavity 11a.

[0111] In other embodiments (not shown in the figures), the rear column drainage structure may be a one-way drainage valve that passes through one of the structural components of the rear column assembly, so that the liquid in the rear column cavity flows unidirectionally to the first rear floor liquid collection structure via the one-way drainage valve.

[0112] In some embodiments, please refer to Figure 7 As shown, the rear pillar assembly 11 includes a rear pillar outer plate 111 and a rear pillar inner plate 112. Please refer to... Figure 8 As shown, the outer panel 111 of the rear column and the inner panel 112 of the rear column are connected.

[0113] In some embodiments, please refer to Figure 8 As shown, the acute angle between any part of the inner wall surface of the rear column inner plate 112 and the height direction can be in the range of 20° to 40°. With this configuration, when liquid drips onto any part of the inner wall surface of the rear column inner plate 112, the liquid is less likely to splash to other locations from any part of the inner wall surface of the rear column inner plate 112. That is, the liquid can flow smoothly downward along the inner wall surface of the rear column inner plate 112, reducing the likelihood of electrical components located in the rear column cavity 11a malfunctioning or experiencing safety issues due to contact with splashed liquid.

[0114] Specifically, the acute angle between any part of the inner wall surface of the rear column inner plate 112 and the height direction can be 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39° or 40°.

[0115] In addition, the inner wall surface of the rear column inner plate 112 can be a structural surface facing the rear column cavity 11a and the rear column outer plate 111.

[0116] In some embodiments, please refer to Figure 8 As shown, the acute angle between any part of the inner wall surface of the rear column outer plate 111 and the height direction can be in the range of 20° to 40°. Under this setting, when liquid drips onto any part of the inner wall surface of the rear column outer plate 111, the liquid is not likely to splash to other positions from any part of the inner wall surface of the rear column outer plate 111. That is, the liquid can flow smoothly downward along the inner wall surface of the rear column outer plate 111, reducing the possibility of electrical components located in the rear column cavity 11a malfunctioning or experiencing safety problems due to contact with splashed liquid.

[0117] Specifically, the acute angle between any part of the inner wall surface of the rear column outer plate 111 and the height direction can be 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39° or 40°.

[0118] In addition, the inner wall surface of the rear column outer plate 111 can be a structural surface facing the rear column cavity 11a and the rear column inner plate 112.

[0119] In some embodiments, please refer to Figure 8 As shown, the rear column assembly 11 may further include a first rear column reinforcing plate 113, which may be located between the rear column outer plate 111 and the rear column inner plate 112. Alternatively, the first rear column reinforcing plate 113 may be located within the rear column cavity 11a, connected to the rear column inner plate 112. A set interval W may exist between the first rear column reinforcing plate 113 and the rear column outer plate 111, satisfying 8mm ≤ W ≤ 15mm. This configuration effectively satisfies the requirement that "liquid in the rear column cavity 11a quickly passes through the space between the first rear column reinforcing plate 113 and the rear column outer plate 111," allowing the liquid to flow smoothly to the rear column drainage structure 12.

[0120] The specific interval W can be 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm or 15mm.

[0121] In addition, the dimension of the interval distance W can be parallel to the direction Y or have an acute angle with the direction Y.

[0122] In some embodiments, please refer to Figures 7-8 As shown, the inner panel 112 of the rear column may include an upper corner plate 112a, a middle plate 112b and a lower corner plate 112c. The upper corner plate 112a is connected to the top of the middle plate 112b, and the bottom of the middle plate 112b is connected to the lower corner plate 112c.

[0123] The rear column drainage structure 12 mentioned above can be set at the bottom of the lower corner plate 112c, and the rear column drainage structure 12 and the lower corner plate 112c can be integrally formed. The first rear column reinforcing plate 113 mentioned above can be connected to the upper corner plate 112a. The side outer plate 3 mentioned above can be connected to the upper corner plate 112a, the middle plate 112b and the lower corner plate 112c respectively.

[0124] At least one of the upper corner plate 112a, middle plate 112b and lower corner plate 112c is provided with a structural hole (or assembly hole). The structural hole can be sealed by sealant, sealing sticker or other sealing components to reduce the possibility of liquid in the rear pillar cavity 11a flowing into or splashing into the cockpit through the structural hole.

[0125] In some embodiments, please refer to Figure 9 As shown, the lower corner plate 112c is connected to the rear column outer plate 111. The rear column assembly 11 may also include a second rear column reinforcing plate 114, which is located within the rear column cavity 11a and between the lower corner plate 112c and the rear column outer plate 111. The second rear column reinforcing plate 114 is connected to the rear column outer plate 111, and a set interval W can be provided between the second rear column reinforcing plate 114 and the lower corner plate 112c, satisfying 8mm≤W≤15mm. Under this configuration, the requirement for "liquid in the rear column cavity 11a to quickly pass through the interval space between the second rear column reinforcing plate 114 and the lower corner plate 112c" can be better met, so that the liquid can flow smoothly to the rear column drainage structure 12.

[0126] The specific interval W can be 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm or 15mm.

[0127] Please refer to Figure 9 As shown, the lower corner plate 112c may be provided with a structural hole, which is covered by a sealing patch 115 to reduce the possibility of liquid in the rear pillar cavity 11a splashing into the cockpit through the structural hole.

[0128] In some embodiments, the rear pillar outer panel mentioned above can be referred to as the D-pillar outer panel, the rear pillar inner panel mentioned above can be referred to as the D-pillar inner panel, the upper corner panel mentioned above can be referred to as the D-pillar upper corner panel, the middle panel mentioned above can be referred to as the D-pillar inner panel reinforcement panel, and the lower corner panel mentioned above can be referred to as the D-pillar lower corner panel.

[0129] In some embodiments, please refer to Figure 1 As shown, the tailgate frame assembly 1 may also include a rear surround assembly 13, which is connected to the rear pillar assembly 11. The rear surround assembly 13 is provided with a rear drain structure 14, and the rear floor 2 is provided with a second rear floor collection structure 23. Please refer to [reference needed]. Figure 10As shown, a second rear floor drainage structure 24 is provided at the bottom of the second rear floor liquid collection structure 23. The height of the rear drainage structure 14 is greater than the height of the second rear floor liquid collection structure 23, and the projection of the rear drainage outlet 141 of the rear drainage structure 14 along the height direction (parallel to direction Z) can be seen on the second rear floor drainage structure 24. Since the height of the rear cavity 13a in the rear assembly 13 is lower than the rear pillar cavity 11a in the rear pillar assembly 11, when the liquid does not enter the rear pillar cavity 11a, the liquid may flow along the tailgate frame sealing strip (not shown in the figure), so that the liquid can flow from the outside of the rear pillar assembly 11 to the outside of the rear assembly 13, thereby making it possible for the liquid to enter the rear cavity 13a of the rear assembly 13. The liquid located in the rear cavity 13a can be drained to the second rear floor drainage structure 24 via the rear drainage structure 14, and then the liquid is drained to the outside of the vehicle body structure by the second rear floor drainage structure 24. With this configuration, liquid is less likely to accumulate in the rear cavity 13a, reducing the likelihood of liquid remaining in the rear cavity 13a for a long time, reducing the likelihood of electrical components in the rear cavity 13a malfunctioning or experiencing safety issues due to contact with liquid, and reducing the likelihood of rust and corrosion on the inner surface of the rear assembly 13.

[0130] In other embodiments, the projection of the rear drainage outlet 141 of the rear drainage structure 14 along the height direction (the direction parallel to direction Z) can also be on the second rear floor liquid collection structure 23. The liquid discharged from the rear drainage outlet 141 can first fall into the second rear floor liquid collection structure 23, and the liquid falling into the second rear floor liquid collection structure 23 can then be discharged to the outside of the vehicle body structure via the second rear floor drainage structure 24.

[0131] In other embodiments, a portion of the projection of the rear drainage outlet 141 of the rear drainage structure 14 along the height direction (the direction parallel to direction Z) can be in the second rear floor collection structure 23, and another portion of the projection can be in the second rear floor drainage structure 24.

[0132] Please refer to Figure 10 As shown, when the amount of liquid discharged from the rear drainage structure 14 is relatively large, or when the vehicle is in a state of acceleration, deceleration or steering, the liquid discharged from the rear drainage structure 14 can be better confined or collected in the second rear floor liquid collection structure 23. The liquid located in the second rear floor liquid collection structure 23 can then flow to the second rear floor drainage structure 24, reducing the possibility of liquid flowing randomly on the rear floor 2 and accumulating on the rear floor 2, thereby reducing the possibility of mold or odor problems on the rear floor 2, and reducing the possibility of electrical components installed on the rear floor 2 coming into contact with liquid and easily malfunctioning or causing safety problems.

[0133] As can be seen from the above, in some embodiments of this application, the rear pillar drainage structure 12 and the rear enclosure drainage structure 14 can form at least two structures for drainage in sequence, reducing the likelihood of liquid accumulation in the cavity of the tailgate frame assembly 1, thereby reducing the likelihood of electrical components located in the cavity of the tailgate frame assembly 1 malfunctioning or experiencing safety issues due to contact with liquid, and reducing the likelihood of rust, corrosion, and other problems on the inner surface of the tailgate frame assembly 1.

[0134] In some embodiments, the tailgate frame assembly 1 may include two rear pillar assemblies 11 disposed opposite to each other in the Y direction, with the rear enclosure assembly 13 located between the two oppositely disposed rear pillar assemblies 11.

[0135] In some embodiments, please refer to Figure 10 As shown, the second rear floor liquid collection structure 23 may include at least two stepped surfaces, and the second rear floor drainage structure 24 may be disposed on the lowest stepped surface. With this configuration, the second rear floor liquid collection structure 23, including at least two steps, can significantly reduce the kinetic energy of the liquid, thereby reliably confining or collecting the liquid within the second rear floor liquid collection structure 23, thus reducing the likelihood of the liquid moving freely relative to the rear floor 2.

[0136] Please refer to Figure 10 As shown, the second rear floor liquid collection structure 23 may include a first step surface 231 and a second step surface 232. The position height of the second step surface 232 is lower than that of the first step surface 231. The second rear floor liquid drainage structure 24 may be disposed on the second step surface 232.

[0137] In other embodiments (not shown in the figures), the second rear floor liquid collection structure may also include other numbers of stepped surfaces that are staggered in the height direction.

[0138] In some embodiments, please refer to Figure 10 As shown, the lowest level of the step surface (e.g., the second level step surface 232 with a relatively low position height) may include a second liquid guiding slope 232a. The second rear floor drainage structure 24 is located at the bottom of the second liquid guiding slope 232a. The second liquid guiding slope 232a has a set inclination angle β, satisfying 3°≤β≤7°. Figure 10The dashed line O represents a horizontal line and is perpendicular to the Z direction. It serves as a reference for measuring the inclination angle β of the second liquid-guiding ramp 232a. When liquid falls from the rear drainage structure 14 onto the second liquid-guiding ramp 232a, it flows along the ramp to the second rear floor drainage structure 24 under gravity, and is then discharged from the second rear floor drainage structure 24 to the outside of the vehicle structure. With this configuration, the second liquid-guiding ramp 232a can quickly guide the liquid to the second rear floor drainage structure 24, allowing for rapid discharge from the second rear floor drainage structure 24 to the outside of the vehicle structure, thus providing a high drainage efficiency.

[0139] The tilt angle β can be 3°, 4°, 5°, 6° or 7°. When the tilt angle β is in the range of 3° to 7°, the second liquid guiding slope 232a can significantly increase the flow velocity of the liquid towards the second rear floor drainage structure 24, and the size of the second liquid guiding slope 232a in the Z direction will not be too large, that is, the second liquid guiding slope 232a is not likely to interfere with the structure below.

[0140] In some embodiments, please refer to Figure 10 As shown, the rear enclosure assembly 13 may include a rear outer panel 131, the bottom of the second liquid guiding ramp 232a may be connected to the rear outer panel 131, and the second rear floor drainage structure 24 may include a second drainage rib 241. Please refer to... Figure 11 As shown, the second drainage rib 241 and the rear outer panel 131 can enclose and form a second drainage cavity 241a, which is connected to the outside of the vehicle body structure. In this configuration, the liquid located in the second rear floor liquid collection structure 23 can flow to the outside of the vehicle body structure via the second drainage cavity 241a.

[0141] in, Figure 11 The view shown is of the second drainage rib 241 observed from the bottom and outside of the vehicle body structure. The protrusion direction of the second drainage rib 241 is direction X, or in other words, the protrusion direction of the second drainage rib 241 is away from the rear outer panel 131, so that a second drainage cavity 241a can be formed between the second drainage rib 241 and the rear outer panel 131. Figure 11 The second fluid-conducting slope 232a shown is observed under perspective.

[0142] Of course, you can also Figure 12 The first rib 221 is observed from the shown perspective. Figure 12 The view shown is from inside the vehicle body structure.

[0143] In some embodiments, please refer to Figure 11As shown, the second rear floor liquid collection structure 23 is also provided with a second extension 233. The second extension 233 extends downward from the bottom of the second liquid guiding slope 232a, and the second extension 233 is attached to the rear outer plate 131. The second liquid drainage rib 241 protrudes relative to the second extension 233 in a direction away from the rear outer plate 131.

[0144] In some embodiments, the second drainage rib 241, the first step surface 231, the second liquid guiding slope 232a, and the second extension 233 can be integrally formed and all serve as part of the rear floor 2, belonging to the same sheet metal part.

[0145] In some embodiments, please refer to Figure 13 As shown, the bottom of the rear outer panel 131 may include a rear flange 131a, and the rear flange 131a can be connected with... Figure 11 The second liquid-filling rib 241 surrounds and forms the second liquid-filling cavity 241a, and the rear flange 131a can be connected with... Figure 11 The second extension 233 is fitted and connected.

[0146] In other embodiments (not shown in the figures), the second drainage cavity may also be formed independently of the rear outer panel, and the second drainage cavity may be mainly formed by the second rear floor drainage structure or the second drainage rib.

[0147] In other embodiments (not shown in the figures), the second rear floor drainage structure can also be a one-way drainage valve, which is installed on and passes through the second rear floor collection structure. Liquid can flow from the second rear floor collection structure to the outside of the vehicle body structure via the one-way drainage valve. Liquid located outside the vehicle body structure cannot flow to the second rear floor collection structure via the one-way drainage valve, which can reduce the possibility of liquid outside the vehicle body structure entering the interior space of the vehicle body structure.

[0148] In some embodiments, please refer to Figure 14 As shown, the inner wall surface of the rear enclosure assembly 13 may include a rear enclosure liquid guiding slope 13b, and the rear enclosure liquid drainage inlet 142 of the rear enclosure liquid drainage structure 14 is disposed at the bottom of the rear enclosure liquid guiding slope 13b. Under the action of gravity, the liquid located in the rear enclosure cavity 13a can accumulate on the rear enclosure liquid guiding slope 13b, and the liquid accumulated on the rear enclosure liquid guiding slope 13b will flow towards the rear enclosure liquid drainage inlet 142 so that the liquid is discharged from the rear enclosure liquid drainage outlet 141. With this configuration, liquid is less likely to accumulate in the rear enclosure cavity 13a, reducing the possibility of liquid remaining in the rear enclosure cavity 13a for a long time, reducing the possibility of electrical components located in the rear enclosure cavity 13a malfunctioning or experiencing safety issues due to contact with liquid, and reducing the possibility of rust, corrosion, and other problems on the inner surface of the rear enclosure assembly 13.

[0149] Among them, the inner wall surface of the rear enclosure assembly 13 and the rear enclosure liquid guiding slope 13b are structural surfaces facing the rear enclosure cavity 13a.

[0150] In addition, the bottom of the inner wall of the rear enclosure assembly 13 may include two opposing rear enclosure liquid guiding slopes 13b, and a rear enclosure liquid drain inlet 142 may be provided between the bottoms of the two opposing rear enclosure liquid guiding slopes 13b.

[0151] In some embodiments, please refer to Figure 10 As shown, the rear enclosure assembly 13 includes an outer rear enclosure panel 131, an inner rear enclosure panel 132, and a rear enclosure reinforcing plate 133. The outer rear enclosure panel 131 and the inner rear enclosure panel 132 are connected, and the rear enclosure reinforcing plate 133 is located between the outer rear enclosure panel 131 and the inner rear enclosure panel 132. Alternatively, the rear enclosure reinforcing plate 133 can be located within the rear enclosure cavity 13a. The rear enclosure reinforcing plate 133 is connected to the inner rear enclosure panel 132. A set interval distance H is provided between the bottom of the rear enclosure reinforcing plate 133 and the rear enclosure drainage inlet 142, satisfying 15mm ≤ H ≤ 25mm. Specifically, the interval distance H can be 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, or 25mm. When the spacing H is within the range of 15mm to 25mm, the bottom of the rear reinforcing plate 133 is not too close to the rear drainage inlet 142, the bottom of the rear reinforcing plate 133 does not easily obstruct the flow of liquid to the rear drainage inlet 142, and the size of the rear reinforcing plate 133 is not too small, nor is the structural strength of the rear reinforcing plate 133 too low, thus ensuring that the overall structural strength of the rear assembly 13 is not too low. Therefore, a spacing H within the range of 15mm to 25mm is preferable.

[0152] The dimension direction of the interval distance H can be parallel to the direction Z, or the dimension direction of the interval distance H can have an acute angle with the direction Z.

[0153] In some embodiments, the rear inner panel 132 may be integrally formed with the rear drainage structure 14, that is, the rear inner panel 132 and the rear drainage structure 14 may be part of the same sheet metal part. The rear drainage structure 14 may include a rib structure, which partially surrounds a drainage cavity connected to the rear cavity 13a. The rib structure of the rear drainage structure 14 may protrude in a direction away from the rear outer panel 131 (e.g., protrude in direction X).

[0154] In other embodiments (not shown in the figures), the rear drainage structure may include a one-way drainage valve, which may be installed in the inner panel of the rear enclosure, allowing liquid in the rear enclosure cavity to flow unidirectionally to the second rear floor drainage structure via the one-way drainage valve.

[0155] In some embodiments, the acute angle between at least a portion of the inner wall surface of the rear inner panel 132 and the height direction (the direction parallel to direction Z) can be in the range of 15° to 25°. With this configuration, when liquid drips onto the inner wall surface of the rear inner panel 132, the liquid is less likely to splash to other locations; that is, the liquid can flow smoothly downwards along the inner wall surface of the rear inner panel 132, reducing the possibility of electrical components located in the rear cavity 13a malfunctioning or experiencing safety issues due to contact with splashed liquid.

[0156] Specifically, the acute angle between at least a portion of the inner wall surface of the rear inner panel 132 and the height direction can be 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24° or 25°.

[0157] In addition, the inner wall surface of the rear inner panel 132 is a structural surface facing the rear cavity 13a and the rear outer panel 131.

[0158] In some embodiments, the acute angle between at least a portion of the inner wall surface of the rear outer panel 131 and the height direction can be in the range of 35° to 45°. Under this configuration, when liquid drips onto at least a portion of the inner wall surface of the rear outer panel 131, the liquid is less likely to splash to other locations; that is, the liquid can flow smoothly downwards along the inner wall surface of the rear outer panel 131, reducing the likelihood of electrical components located in the rear cavity 13a malfunctioning or experiencing safety issues due to contact with splashed liquid.

[0159] Specifically, the acute angle between at least a portion of the inner wall surface of the rear outer panel 131 and the height direction can be 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44° or 45°.

[0160] In addition, the inner wall surface of the rear outer panel 131 is a structural surface facing the rear cavity 13a and the rear inner panel 132.
