Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a rear electric seat motor mounting base and a vehicle having the same. Background Technology

[0002] In order to improve the installation strength of the rear seats and reduce costs, steel hooks on the rear seat backs are usually welded to C-rings. The C-rings on the vehicle body are used to support the steel hooks. At this time, the rear seat backs are fixed relative to the vehicle body and cannot be adjusted.

[0003] To improve vehicle comfort, more and more vehicles are using electric motors to adjust the angle of the rear seats.

[0004] In existing technologies, the electric drive structure of rear electric seats generally uses a motor to move steel hooks on the seat back to adjust the seat back angle. To accommodate this structure, the steel hooks are no longer welded to the C-ring of the vehicle body. Furthermore, the steel hooks connected to the motor need to be positioned on the side of the seat to meet the requirements of fore-and-aft movement, resulting in poorer support compared to traditional fixed designs in terms of force direction. Additionally, when the electric drive seat back is adjusted to its maximum forward or rearward angle, the steel hook cantilever is longer than that of a fixed steel hook, further reducing support. This leads to a decrease in the modal characteristics of the rear seat, affecting the overall NVH (Noise, Vibration, Harshness) performance of the vehicle. Utility Model Content

[0005] This utility model provides a rear electric seat motor mounting structure and a vehicle having the same. The rear electric seat motor mounting structure can improve the lateral mounting strength of the rear seat and optimize the overall vehicle NVH (noise, vibration, and harshness) performance.

[0006] This utility model provides a rear electric seat motor mounting structure, including a drive mechanism, a bracket assembly, a rear side panel, a lower C-pillar panel, a C-pillar reinforcing plate, and a wheel arch inner panel bracket. The drive mechanism is mounted on the bracket assembly, and at least two of the rear side panel, the lower C-pillar panel, the C-pillar reinforcing plate, and the wheel arch inner panel bracket are connected to the bracket assembly.

[0007] Furthermore, the rear inner panel of the side enclosure, the lower inner panel of the C-pillar, the C-pillar reinforcing plate, and the wheel arch inner panel bracket are all connected to the bracket assembly.

[0008] Furthermore, a first cavity is formed between the bracket assembly and the rear inner panel of the side wall, the lower inner panel of the C-pillar, the C-pillar reinforcing plate, and the inner panel bracket of the wheel arch.

[0009] Furthermore, the bracket assembly includes a reinforcing bracket, which includes a first plate and a plurality of connecting edges formed on the first plate. The rear inner side panel, the lower inner C-pillar panel, the C-pillar reinforcing plate, and the wheel arch inner panel bracket are each connected to the first plate of the reinforcing bracket through at least one of the connecting edges.

[0010] Furthermore, the bracket assembly includes a mounting bracket, the drive mechanism is disposed on the mounting bracket, and the mounting bracket is disposed on the reinforcing bracket.

[0011] Furthermore, a first cavity is formed between the first plate, the rear inner side panel, the lower inner C-pillar panel, the C-pillar reinforcing plate, the wheel arch inner panel bracket, and the plurality of connecting edges.

[0012] Furthermore, the bracket assembly includes a support frame, the middle of which protrudes toward the direction of the reinforcing bracket, both ends of which are fixed to the inner plate bracket of the wheel cover, and at least one connecting edge of the first plate is fixed to the middle of the support frame.

[0013] Furthermore, the rear electric seat motor mounting structure includes a rear side panel reinforcement plate, a wheel arch outer plate, and a side panel outer plate. The rear side panel reinforcement plate and the wheel arch outer plate are fixed to the side panel outer plate. A second cavity is formed between the rear side panel inner plate, the lower C-pillar inner plate, the C-pillar reinforcement plate, the rear side panel reinforcement plate, and the wheel arch outer plate.

[0014] Furthermore, a third cavity is formed between the rear reinforcing plate of the side enclosure, the outer plate of the wheel cover, and the outer plate of the side enclosure.

[0015] Furthermore, in the vehicle width direction, the first cavity, the second cavity, and the third cavity all partially overlap.

[0016] This utility model also provides a vehicle including the aforementioned rear electric seat motor mounting structure.

[0017] In summary, in this invention, by simultaneously connecting the bracket assembly to at least two of the following structures—the rear inner panel of the side wall, the lower inner panel of the C-pillar, the C-pillar reinforcing plate, and the wheel arch inner panel bracket—the drive mechanism is fixed to the side of the vehicle body. Furthermore, the force acting on the drive mechanism can be distributed through the bracket assembly to the connected structures in these three areas. Individual parts are no longer subject to the overall force and vibration of the drive mechanism. Therefore, this mounting structure improves the lateral mounting strength of the rear seats and optimizes the overall NVH performance of the vehicle. Moreover, the arrangement of multiple cavities and their relative positions further enhances the strength of the mounting structure and optimizes the vehicle's NVH performance.

[0037] This utility model provides a rear electric seat motor mounting structure and a vehicle having the same. The rear electric seat motor mounting structure can improve the lateral mounting strength of the rear seat and optimize the overall vehicle NVH performance.

[0038] Please see Figure 1 , Figure 2 , Figure 6 and Figure 7 The rear electric seat motor mounting structure provided in this embodiment includes a drive mechanism 10, a bracket assembly 20, a rear side panel 31, a lower C-pillar panel 32, a C-pillar reinforcing plate 33, and a wheel arch inner panel bracket 34. The drive mechanism 10 is mounted on the bracket assembly 20, and at least two of the rear side panel 31, the lower C-pillar panel 32, the C-pillar reinforcing plate 33, and the wheel arch inner panel bracket 34 are connected to the bracket assembly 20.

[0039] In this embodiment, by simultaneously connecting the bracket assembly 20 to at least two of the following structures: the rear inner panel of the side wall 31, the lower inner panel of the C-pillar 32, the C-pillar reinforcement plate 33, and the wheel arch inner panel bracket 34, the drive mechanism 10 is fixed to the side of the vehicle body. The force acting on the drive mechanism 10 can be distributed through the bracket assembly 20 to the connected structures in the rear inner panel of the side wall 31, the lower inner panel of the C-pillar 32, the C-pillar reinforcement plate 33, and the wheel arch inner panel bracket 34. Individual components are no longer subject to the overall force and vibration of the drive mechanism 10. Therefore, this mounting structure can improve the lateral mounting strength of the rear seats and optimize the overall NVH performance of the vehicle.

[0040] Preferably, the bracket assembly 20 is simultaneously connected to the rear inner panel 31 of the side wall, the lower inner panel 32 of the C-pillar, the C-pillar reinforcing plate 33, and the inner panel bracket 34 of the wheel arch.

[0041] Please continue reading Figures 1 to 7 In this embodiment, the drive mechanism 10 may include a motor 11 and a steel hook 12. The bracket assembly 20 includes a reinforcing bracket 21 and a mounting bracket 22. The motor 11 and the steel hook 12 are mounted on the mounting bracket 22, and the mounting bracket 22 is mounted on the reinforcing bracket 21. The reinforcing bracket 21 includes a first plate 211 and a plurality of connecting edges 212 formed on the first plate 211. The rear inner side panel 31, the lower inner C-pillar panel 32, the C-pillar reinforcing plate 33, and the wheel arch inner panel bracket 34 are each connected to the first plate 211 of the reinforcing bracket 21 through at least one connecting edge 212.

[0042] To further improve strength and optimize the overall vehicle NVH performance, a first cavity 41 is formed between the bracket assembly 20 and the rear side panel 31, the lower C-pillar panel 32, the C-pillar reinforcing plate 33, and the wheel arch inner panel bracket 34 (see...). Figure 7 To form the aforementioned first cavity 41, in this embodiment, at least a portion of the connecting edge 212 is bent away from the rear seats relative to the first plate 211, i.e., towards the outer side of the vehicle body. When the reinforcing bracket 21 is installed on the vehicle body, the first cavity 41 is formed between the first plate 211 of the reinforcing bracket 21, the plurality of connecting edges 212, the rear inner panel 31 of the side panel, the lower inner panel 32 of the C-pillar, the C-pillar reinforcing plate 33, and the inner panel bracket 34 of the wheel arch.

[0043] Furthermore, the mounting bracket 22 includes a second plate 221 and a mounting edge 222 formed on the second plate 221. The motor 11 is fixed to the mounting edge 222, and the output shaft of the motor 11 passes through the mounting edge 222 and is connected to the steel hook 12, thereby driving the steel hook 12 to move.

[0044] The second plate 221 is fixed to the first plate 211 by a connector to complete the fixation between the mounting bracket 22 and the reinforcing bracket 21. A protruding reinforcing part 2111 is formed on the first plate 211 at the position where it connects with the second plate 221 to strengthen the connection between the first plate 211 and the second plate 221.

[0045] Please continue reading Figure 5 The bracket assembly 20 also includes a support frame 23, the middle of which protrudes towards the reinforcing bracket 21. Both ends of the support frame 23 are fixed to the inner wheel arch support 34. At least one connecting edge 212 of the first plate 211 is fixed to the middle of the support frame 23. That is, the first plate 211 is fixed to the inner wheel arch support 34 via a connecting edge 212 and the support frame 23. The provision of the support frame 23 increases the adaptability of the bracket assembly 20 and further improves the connection strength of the mounting structure.

[0046] Please continue reading Figures 6 to 12 The rear electric seat motor mounting structure also includes a rear side panel reinforcement plate 35, a wheel arch outer plate 36, and a side panel outer plate 37. The rear side panel reinforcement plate 35 and the wheel arch outer plate 36 are fixed to the side panel outer plate 37.

[0047] The aforementioned rear inner side panel 31, lower inner C-pillar panel 32, and C-pillar reinforcing plate 33 are all simultaneously fixed to the rear reinforcing plate 35 of the side panel and the outer wheel arch panel 36. A second cavity 42 is formed between the rear inner side panel 31, lower inner C-pillar panel 32, C-pillar reinforcing plate 33, rear reinforcing plate 35 of the side panel, and outer wheel arch panel 36. It should be noted that... Figure 7 and Figure 11The relevant structure of the second cavity is shown. Since it is a cross-sectional view, and the rear side panel 31, the lower C-pillar panel 32, and the C-pillar reinforcing plate 33 are arranged along the front-rear direction of the vehicle, therefore, in Figure 7 and Figure 11 Of the three components—the rear inner panel 31 of the side wall, the lower inner panel 32 of the C-pillar, and the C-pillar reinforcing plate 33—only the structure of the rear inner panel 31 of the side wall is shown. Figure 11 The section with the diagonal line is a schematic diagram of the second cavity 42.

[0048] The addition of the second cavity 42 further enhances the strength of the mounting structure and optimizes NVH performance.

[0049] Furthermore, in this embodiment, the first cavity 41 is closer to the inner side of the vehicle body than the second cavity 42, and when viewed along the width direction of the vehicle, the first cavity 41 and the second cavity 42 at least partially overlap. In other words, as... Figure 9 As shown, in the Y direction of the vehicle (i.e., the width direction of the vehicle), there is at least one straight line at a set height that is parallel to the Y direction of the vehicle (see...). Figure 9 The dashed line L in the diagram can pass through both the first cavity 41 and the second cavity 42 at the same time.

[0050] Please continue reading Figures 8 to 12 A third cavity 43 is formed between the rear reinforcing plate 35 of the side enclosure, the outer wheel cover plate 36, and the outer side enclosure plate 37. Figure 12 The part marked with a slash is a schematic diagram of the third cavity 43.

[0051] In the width direction of the vehicle, the second cavity 42 is located between the first cavity 41 and the third cavity 43. The second cavity 42 and the third cavity 43 at least partially overlap. Preferably, in the width direction of the vehicle, the first cavity 41, the second cavity 42, and the third cavity 43 all partially overlap. That is, as shown... Figure 9 As shown by the dashed line L, this dashed line can pass through the first cavity 41, the second cavity 42 and the third cavity 43 simultaneously.

[0052] By stacking three cavities along the width of the vehicle, the strength of the mounting structure can be further improved, and the vehicle's NVH performance can be optimized.

[0053] In summary, in this invention, by simultaneously connecting the bracket assembly 20 to at least two of the following components—the rear inner panel 31 of the side wall, the lower inner panel 32 of the C-pillar, the C-pillar reinforcing plate 33, and the wheel arch inner panel bracket 34—the drive mechanism 10 is fixed to the side of the vehicle body. Furthermore, the force acting on the drive mechanism 10 can be distributed through the bracket assembly 20 to the connected structures within the following components: the rear inner panel 31 of the side wall, the lower inner panel 32 of the C-pillar, the C-pillar reinforcing plate 33, and the wheel arch inner panel bracket 34. Individual parts are no longer subjected to the overall force and vibration of the drive mechanism 10. Therefore, this mounting structure can improve the lateral mounting strength of the rear seats and optimize the overall NVH performance of the vehicle. Moreover, the arrangement of multiple cavities and their relative positions further enhances the strength of the mounting structure and optimizes the vehicle's NVH performance.
