Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a center channel assembly, a floor assembly, and a vehicle. Background Technology

[0002] The center tunnel assembly of a vehicle is typically located in the center of the vehicle chassis, extending from front to rear. The center tunnel assembly protects some important components under the vehicle, and as part of the body structure, it enhances the overall strength and torsional rigidity of the vehicle body.

[0003] For high-profile center tunnel assemblies, a split structure is typically used. During manufacturing, it is assembled from multiple components. For example, the center tunnel assembly includes a top plate and two side plates, spaced apart in the left-right direction. The top plate is located between the two side plates, with its edge extending downwards and overlapping and welding with the side plates in the left-right direction. However, when welding the top plate and side plates in the left-right direction of the vehicle, the space for welding is limited and the operation is inconvenient due to the obstruction of the other side plate. Utility Model Content

[0004] To address the aforementioned technical issues, this application provides a center channel assembly, a floor assembly, and a vehicle, which increases the operating space on both sides of the overlapping area of ​​the splicing components in the overlapping direction, thereby improving assembly convenience.

[0005] On one hand, this application provides a center channel assembly, which includes a side plate and a top plate. The top plate is located between adjacent side plates and is connected to the adjacent side plates respectively to form a downward open structure. The top plate and the side plates are overlapped along the vertical direction of the center channel assembly.

[0006] In one embodiment of this application, the side plate includes a main body and a bent portion, the bent portion being connected to the main body, and the top plate and the bent portion being overlapped along the vertical direction of the central channel assembly.

[0007] In one embodiment of this application, in the left-right direction of the central channel assembly, the main body is located on the side of the bend away from the top plate.

[0008] In one embodiment of this application, the main body includes a support portion and a connecting portion, the connecting portion being connected between the support portion and the bending portion, and having an angle with the support portion and the bending portion respectively.

[0009] In one embodiment of this application, the top plate includes reinforcing ribs disposed between adjacent bends.

[0010] In one embodiment of this application, the main body includes a front section, a middle section, and a rear section connected sequentially along the front-rear direction of the central channel assembly. In the vertical direction of the central channel assembly, the height of the middle section is greater than the height of the front section and the height of the rear section, respectively.

[0011] In one embodiment of this application, the front section is inclined toward the side away from the top plate in the left-right direction of the middle channel assembly relative to the middle section.

[0012] In one embodiment of this application, a notch is provided at the edge of the bend where the front and middle sections intersect.

[0013] On the other hand, this application also provides a floor assembly, which includes the aforementioned center channel assembly.

[0014] Furthermore, this application also provides a vehicle that includes the aforementioned floor assembly.

[0015] The technical solution described in this application has the following advantages over the prior art:

[0016] The central channel assembly includes side plates and a top plate. The top plate is located between adjacent side plates and connected to them to form a downwardly open structure. The top plate and side plates overlap along the vertical direction of the central channel assembly. With the vertical direction of the central channel assembly as a reference, there are no other components obstructing the overlapping area of ​​the top plate and side plates, providing a wide spatial passage for connection operations. For example, during welding, welding equipment can approach the overlapping area more freely from both sides and can more easily adjust the welding angle and position, allowing for precise control of the welding process and significantly improving operational flexibility. Therefore, this application increases the operating space on both sides of the overlapping area in the vertical direction of the central channel assembly, improving assembly convenience.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] The central tunnel assembly extends along the vehicle's longitudinal direction and is typically located on the central axis of the vehicle floor. As a key component of the vehicle body, it undertakes multiple protective and mechanical functions: on the one hand, it forms a protective barrier for core chassis components such as the drive shaft, exhaust pipe, brake lines, fuel lines, and wiring harness, effectively resisting impacts from road debris; on the other hand, by strengthening the body structure, it significantly improves the vehicle's torsional rigidity, playing a role in energy absorption, buffering, and force transmission in collision accidents, dispersing the impact force to other parts of the vehicle body, and maximizing the safety of passengers.

[0030] The manufacturing method of the center channel assembly varies depending on its structural height. For low-profile center channel assemblies, a one-piece stamping process can be used; while high-profile center channel assemblies generally employ a split design, formed by assembling multiple components. Taking a common split structure as an example, it consists of a top plate and two side plates. The side plates are symmetrically arranged along the left-right direction of the center channel assembly, with the top plate mounted on top of the side plates, its edge extending downwards to overlap and weld with the side plates along the left-right direction of the center channel assembly. However, this design has significant drawbacks during welding: during the transverse butt welding of the top and side plates, the presence of the other side plate greatly restricts the movement space of the welding equipment, leading to difficulties in equipment positioning and operational limitations. This not only severely reduces welding efficiency but also easily causes quality problems such as incomplete welds and insufficient penetration.

[0031] To address the aforementioned technical bottlenecks, this application optimizes the connection design between the top plate and the side plate. By adjusting their connection positions, the welding operation space is successfully expanded, thereby improving welding quality and production efficiency. Specifically, the vertical direction (corresponding to the vertical direction of the vehicle) of the central channel assembly is designated as the first direction F1, the horizontal direction (corresponding to the horizontal direction of the vehicle) is designated as the second direction F2, and the front-rear direction (corresponding to the front-rear direction of the vehicle) is designated as the third direction F3.

[0032] Please see Figures 1 to 3 , Figure 1 This is a three-dimensional structural schematic diagram of the channel assembly in this application. Figure 2 yes Figure 1 The diagram shown is a 3D exploded view of the channel assembly. Figure 3 yes Figure 1 Sectional view of E1-E1.

[0033] This application provides a central channel assembly, which includes side panels 10 and a top panel 30. The top panel 30 is located between adjacent side panels 10 and connected to each adjacent side panel 10 to form a downwardly open structure. The top panel 30 and the side panels 10 are overlapped along a first direction F1.

[0034] Specifically, taking a plane perpendicular to the front-rear direction of the center channel assembly as the cutting plane, the cross-section of the center channel assembly is roughly "U"-shaped. The bottom end of the center channel assembly forms a downward-opening opening 20.

[0035] The center channel assembly includes two side plates 10, which are spaced apart in the second direction F2. The two side plates 10 may be identical or different. In the illustrated embodiment, the two side plates 10 are generally symmetrically arranged along the left-right direction of the center channel assembly. For ease of description, the two side plates 10 are respectively named the first side plate 10A and the second side plate 10B.

[0036] The first side plate 10A and the second side plate 10B are spaced apart in the left-right direction of the center channel assembly. The top plate 30 is located between the first side plate 10A and the second side plate 10B in the left-right direction of the center channel assembly, and is connected to the top of the first side plate 10A and the top of the second side plate 10B, respectively. The bottom of the first side plate 10A and the second side plate 10B are respectively provided with flanges, and are respectively welded to the vehicle floor through the flanges.

[0037] Please see Figure 4 , Figure 4 yes Figure 3 Enlarged view of partial view A in the middle.

[0038] The connection point between the first side plate 10A and the top plate 30 is the first connection area S1. In the first connection area S1, the first side plate 10A and the top plate 30 overlap and connect in the first direction F1.

[0039] The connection between the second side plate 10B and the top plate 30 is the second connection area S2. In the second connection area S2, the second side plate 10B and the top plate 30 overlap and connect in the first direction F1.

[0040] In some embodiments, the top plate 30 is welded to the first side plate 10A and the second side plate 10B in the first direction F1 by double-sided spot welding. For example, the two electrodes 40 of the welding equipment are located on both sides of the second connection area S2, and pressure is applied and energized at the same time to form a spot weld nugget connecting the second side plate 10B and the top plate 30.

[0041] Please refer to the following: Figure 5 , Figure 5 yes Figure 1 The diagram shows a projection of the middle channel assembly onto the first direction F1.

[0042] The first projection P1 of the first connecting region S1 does not overlap with the projection of the rest of the central channel assembly, so that the first connecting region S1 is unobstructed on both sides in the first direction F1. Specifically, the first projection P1 of the first connecting region S1 is located on one side of the second projection P2 of the rest of the first side plate 10A, the third projection P3 of the rest of the top plate 30, and the fourth projection P4 of the second side plate 10B.

[0043] The fifth projection P5 of the second connecting region S2 does not overlap with the projection of the rest of the central channel assembly, so that the second connecting region S2 is unobstructed on both sides in the first direction F1. Specifically, the fifth projection P5 of the second connecting region S2 is located on one side of the sixth projection P6 of the rest of the second side plate 10B, the seventh projection P7 of the rest of the top plate 30, and the eighth projection P8 of the first side plate 10A.

[0044] In this embodiment, with the first direction F1 as a reference, there are no other components obstructing the overlapping area of ​​the top plate 30 and the side plate 10, providing a wide spatial passage for the connection operation. For example, during the welding connection process, the welding equipment can approach the overlapping area more freely from both sides and can more easily adjust the welding angle and position, allowing for precise control of the welding process and significantly improving operational flexibility. Therefore, this application increases the operating space on both sides of the overlapping area in the first direction F1, improving assembly convenience.

[0045] In some embodiments, the central channel assembly further includes structural adhesive (not shown), which is sandwiched between the top plate 30 and the side plate 10. Specifically, in the first connection region S1, the top plate 30 and the first side plate 10A are bonded together on a pair of opposing surfaces in the first direction F1 by structural adhesive. In the second connection region S2, the top plate 30 and the second side plate 10B are bonded together on a pair of opposing surfaces in the first direction F1 by structural adhesive.

[0046] On the one hand, the structural adhesive can improve the connection strength between the top plate 30 and the side plate 10; on the other hand, the structural adhesive can seal the connection between the top plate 30 and the side plate 10.

[0047] Please see Figure 4 In some embodiments, the side panel 10 includes a main body 110 and a bent portion 120, the bent portion 120 being connected to the main body 110, and the top panel 30 being overlapped with the bent portion 120 along a first direction F1.

[0048] Specifically, in the first side plate 10A, the bent portion 120 of the first side plate 10A is connected to the top edge of the main body portion 110 of the first side plate 10A and extends toward the second side plate 10B. The connection between the bent portion 120 of the first side plate 10A and the main body portion 110 of the first side plate 10A has a first included angle θ1. In the second side plate 10B, the bent portion 120 of the second side plate 10B is connected to the top edge of the main body portion 110 of the second side plate 10B and extends toward the first side plate 10A. The connection between the bent portion 120 of the second side plate 10B and the main body portion 110 of the second side plate 10B has a second included angle θ2. One end of the top plate 30 in the left-right direction of the central channel assembly is stacked and connected to the bent portion 120 in the first side plate 10A in the vertical direction of the central channel assembly. The other end of the top plate 30 in the left-right direction of the middle channel assembly is stacked and connected to the bent portion 120 in the second side plate 10B in the vertical direction of the middle channel assembly.

[0049] In some embodiments, the side panel 10 can be integrally formed by a stamping process.

[0050] In this embodiment, the top of the side plate 10 is bent in the left-right direction of the central channel assembly to overlap with the top plate 30, and then connected at the overlap, thus realizing the structure in which the top plate 30 and the side plate 10 are overlapped in the vertical direction of the central channel assembly.

[0051] Please see Figure 6 and Figure 7 , Figure 6 yes Figure 3 Enlarged view of partial view B in the middle. Figure 7 yes Figure 3 A magnified view of partial view C in the middle.

[0052] In some embodiments, in the second direction F2, the main body 110 is located on the side of the bend 120 away from the top plate 30.

[0053] Specifically, taking the vertical direction of the central channel assembly as the projection direction, the bent portion 120 in the first side plate 10A has a ninth projection, and the main body portion 110 in the first side plate 10A has a tenth projection. In the horizontal direction of the central channel assembly, the tenth projection is located on the side of the ninth projection away from the top plate 30, that is, the ninth projection and the tenth projection do not overlap. Taking the vertical direction of the central channel assembly as the projection direction, the bent portion 120 in the second side plate 10B has an eleventh projection, and the main body portion 110 in the second side plate 10B has a twelfth projection. In the horizontal direction of the central channel assembly, the twelfth projection is located on the side of the eleventh projection away from the top plate 30, that is, the eleventh projection and the twelfth projection do not overlap.

[0054] In the vertical direction of the central channel assembly, the main body 110 does not obstruct the bending portion 120, further expanding the overlapping area of ​​the top plate 30 and the side plate 10 (bending portion 120) in the unobstructed area on the lower side.

[0055] Please continue reading. Figure 6 and Figure 7 In some embodiments, the main body 110 includes a support portion 1121 and a connecting portion 1122, the connecting portion 1122 being connected between the support portion 1121 and the bending portion 120, and having an angle with the support portion 1121 and the bending portion 120 respectively.

[0056] Specifically, the connecting portion 1122 forms an angle with both the supporting portion 1121 and the bending portion 120. The supporting portion 1121 is used to connect to the vehicle floor. In the first side panel 10A, the connection point between the connecting portion 1122 and the bending portion 120 of the first side panel 10A has a first angle θ1, and the connection point between the connecting portion 1122 and the supporting portion 1121 of the first side panel 10A has a third angle θ3. In the second side panel 10B, the connection point between the connecting portion 1122 and the bending portion 120 of the second side panel 10B has a second angle θ2, and the connection point between the connecting portion 1122 and the supporting portion 1121 of the second side panel 10B has a fourth angle θ4.

[0057] During use, the central tunnel assembly carries items (such as storage boxes) on top. The weight of these items acts on the top plate 30, and is then transferred from the top plate 30 to the bending section 120. The bending section 120 then transfers the weight to the support section 1121 via the connecting section 1122, and finally to the floor. The connecting section 1122 forms an angle with both the bending section 120 and the support section 1121, which helps to distribute the force.

[0058] Please see Figure 4 In some embodiments, the top plate 30 includes reinforcing ribs 320 disposed between adjacent bends 120.

[0059] Specifically, the top plate 30 includes a body 310 and a reinforcing rib 320. The body 310 is located below the bends 120 and overlaps with and connects to the two bends 120 respectively. The reinforcing rib 320 is disposed on the body 310. The reinforcing rib 320 is a protrusion extending upward along the first direction F1. The reinforcing rib 320 extends in the front-rear direction of the central channel assembly, and is located between two adjacent bends 120 in the left-right direction of the central channel assembly.

[0060] The reinforcing rib 320 is placed between adjacent bends 120, making reasonable use of the space between them and reducing the impact of the reinforcing rib 320 on the height of the central channel assembly.

[0061] Please see Figure 8 , Figure 8 yes Figure 1 The side view of the channel assembly shown.

[0062] In some embodiments, the main body 110 includes a front section 111, a middle section 112, and a rear section 113 connected sequentially along a third direction F3. In the first direction F1, the height of the middle section 112 is greater than the height of the front section 111 and the height of the rear section 113.

[0063] Specifically, the bottoms of the front section 111, the middle section 112, and the rear section 113 are respectively used to connect with the floor, and the tops of the front section 111, the middle section 112, and the rear section 113 are respectively connected with the bending portion 120. The middle section 112 has the aforementioned support portion 1121 and connecting portion 1122. The main body portion 110 of the first side plate 10A and the main body portion 110 of the second side plate 10B both adopt this structure.

[0064] The top of the front section 111 is lower than the top of the middle section 112, allowing space above the front section 111 to place a reinforcing beam without increasing its height. The reinforcing beam extends in the longitudinal direction of the central tunnel assembly, and its front end connects to the front bulkhead crossbeam of the vehicle. The reinforcing beam is used to transmit collision forces in the longitudinal direction of the central tunnel assembly.

[0065] The top of the rear section 113 is lower than the top of the middle section 112, and the floor protrusion height is lower at the corresponding rear passenger position.

[0066] Please see Figure 9 , Figure 9 yes Figure 1 The top view of the total component solution state of the middle channel is shown.

[0067] In some embodiments, the front section 111 is inclined relative to the middle section 112 in the second direction F2 toward the side away from the top plate 30.

[0068] Specifically, the front section 111 has a first end and a second end opposite to each other in the front-rear direction of the middle channel assembly. The first end is connected to the middle section 112. In the left-right direction of the middle channel assembly, the second end is located on the side of the first end opposite to the top plate 30.

[0069] In the first side plate 10A, the front section 111 and the middle section 112 have a fifth included angle θ5. In the second side plate 10B, the front section 111 and the middle section 112 have a sixth included angle θ6.

[0070] The side panel 10 and the roof panel 30 are connected to the front bulkhead of the vehicle at one end in the front-rear direction of the central tunnel assembly. In the event of a frontal collision, the front bulkhead transmits the impact force to the side panel 10 and the roof panel 30 respectively. The front section 111 is inclined relative to the middle section 112, causing the impact force to change direction during transmission, forming a non-linear force transmission path. This arrangement allows the impact force borne by the side panel 10 to be more effectively dispersed.

[0071] In some embodiments, a notch 121 is provided on the edge of the bent portion 120 at the intersection of the corresponding front section 111 and the middle section 112. Since the bent portion 120 is connected to the front section 111 and the middle section 112 respectively, by providing the notch 121, stress can be dispersed during the forming process, reducing the risk of the bent portion 120 cracking at the intersection of the corresponding front section 111 and the middle section 112.

[0072] This application also provides a floor assembly, which includes the center channel assembly of any of the above embodiments. Specifically, the floor assembly includes two sill beams, a floor, and a center channel assembly. The two sill beams are spaced apart in the left-right direction of the center channel assembly. The floor is connected between the two sill beams. The center channel assembly is located between the two sill beams and connected to the floor. The center channel assembly protrudes from the floor in the vertical direction of the vehicle.

[0073] The floor assembly includes all the technical features of the center channel assembly; therefore, the floor assembly also includes all the technical effects of the center channel assembly, which will not be elaborated here.

[0074] This application also provides a vehicle that includes the aforementioned floor assembly.

[0075] Note that the above are merely preferred embodiments and the technical principles employed in this application. Those skilled in the art will understand that this application is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of this application. Therefore, although this application has been described in detail through the above embodiments, this application is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of this application, the scope of which is determined by the scope of the appended claims.
