Description

Technical Field

[0001] The utility model specifically relates to a vehicle rear structure and a vehicle. Background Art

[0002] In the related art, some vehicles adopt a design scheme at the rear that: a mounting plate for providing mounting points for the second row of retractors and a plurality of reinforcing plates (or reinforcing members) for reinforcing the rear structure of the vehicle are arranged relatively dispersedly.

[0003] The inventors of this case have discovered that the disadvantage of this solution of relatively dispersed arrangement of the reinforcing plate and the mounting plate is that there is no obvious correlation or synergy between the reinforcing plate and the mounting plate, and they cannot cooperate with each other to strengthen the rear structure of the vehicle.

[0004] In addition, some design solutions, based on the dispersed arrangement of the reinforcement plate and the mounting plate, also design a bracket specifically used to support the mounting plate between the mounting plate and the wheel cover assembly; in such solutions, the bracket, mounting plate and reinforcement plate are all dispersedly arranged at the rear of the vehicle. It is understandable that the design of the bracket will not significantly strengthen the rear structure of the vehicle, but only ensure the stability of the mounting plate; at the same time, the existence of the bracket will increase the weight of the vehicle to a certain extent, which is not conducive to the lightweighting of the vehicle.

[0049] Embodiment 1

[0050] like Figure 1 and Figure 2 As shown, this embodiment provides a vehicle, wherein the left rear part and the right rear part of the vehicle are respectively provided with a D-pillar assembly 1, a wheel cover assembly 2, a retractor 3, a reinforcement 4 and a first plate 5; the rear structure design of the vehicle is described below by taking the left rear structure of the vehicle as an example:

[0051] Among them, the reinforcement 4 is supported between the D-pillar assembly 1 and the wheel housing assembly 2, and is fixedly connected to the D-pillar assembly 1 and the wheel housing assembly 2 at its upper and lower ends respectively; the first plate 5 is mounted inside the reinforcement 4, the first plate 5 is fixedly connected to the reinforcement 4, and the first plate 5 is also fixedly connected to the retractor 3 to provide a mounting point for the retractor 3; at the same time, the retractor 3 is also inside the reinforcement 4, and the retractor 3 is used to retract and release the safety belt 6 for the second row of seats 8; corresponding to the safety belt 6, a through-opening 41 is provided on the reinforcement 4, and the through-opening 41 is used for the safety belt 6 to enter and exit the reinforcement 4.

[0052] As can be seen from the above, based on the design that the reinforcement 4 is supported between the D-pillar assembly 1 and the wheel housing assembly 2, the presence of the reinforcement 4 can improve the rigidity and torsional performance of the rear structure of the vehicle; based on the vehicle adopting the arrangement that the reinforcement 4 and the first plate 5 (for installing the retractor 3) are concentrated together, this arrangement can make the reinforcement 4 and the first plate 5 obviously associated and coordinated. For the first plate 5, the first plate 5 can have good rigidity and stability because it is installed inside the reinforcement 4 and connected to the reinforcement 4; for the reinforcement 4, the above arrangement can obviously make the reinforcement 4 have good rigidity and structural stability because of the first plate 5 installed inside it. Furthermore, for the first plate 5, since it has good rigidity and structural stability, it is obviously unnecessary to design an additional bracket that is only used to support the first plate 5 as described in the background technology.

[0053] For the above vehicle, the following is a more detailed example setting:

[0054] Please continue reading Figure 1 and Figure 2The reinforcement member 4 of this embodiment is a U-shaped body, which is through from top to bottom and has an opening toward the outside of the vehicle. Correspondingly, the rear structure of the vehicle further includes a C-pillar upper inner plate 7. When the rear structure of the vehicle is assembled, the reinforcement member 4, the C-pillar upper inner plate 7, the D-pillar assembly 1 and the wheel cover assembly 2 enclose a space, and the aforementioned first plate member 5 and the retractor 3 are both installed in the space.

[0055] Based on the above, in order to form the aforementioned U-shaped structure, the reinforcement 4 of the present embodiment specifically includes a main body 42, a first side wall 43 and a second side wall 44, wherein the main body 42, the first side wall 43 and the second side wall 44 are all special-shaped parts, the first side wall 43 is located at the front side of the second side wall 44, the main body 42 is welded to the first side wall 43 and the second side wall 44 at the front and rear parts thereof, respectively, the first side wall 43 has a portion extending from the connection with the main body 42 toward the outside of the vehicle, and the second side wall 44 also has a portion extending from the connection with the main body 42 toward the outside of the vehicle.

[0056] In this embodiment, the D-pillar assembly 1 further includes a D-pillar upper inner plate 11 and a D-pillar lower inner plate 12; when the rear structure of the vehicle is assembled, Figure 3 As shown, the upper end of the main body 42 is welded to the D-pillar assembly 1, and the lower end of the main body 42 is welded to the wheel cover assembly 2; the upper end of the first side wall 43 is welded to the D-pillar upper inner panel 11 and the C-pillar upper inner panel 7, the lower end of the first side wall 43 is welded to the wheel cover assembly 2, and between the upper and lower ends of the first side wall 43, the first side wall 43 is welded to the C-pillar upper inner panel 7 and the wheel cover assembly 2; the upper end of the second side wall 44 is welded to the D-pillar lower inner panel 12, the lower end of the second side wall 44 is welded to the wheel cover assembly 2, and between the upper and lower ends of the second side wall 44, the second side wall 44 is welded to the C-pillar upper inner panel 7 and the wheel cover assembly 2.

[0057] It should be noted that the reinforcement 4 of this embodiment is also welded to the C-pillar upper inner plate 7 and surrounded by the outer periphery of the first plate 5. Therefore, the reinforcement 4 of this embodiment is actually a part that is supported between the D-pillar assembly 1 and the wheel housing assembly 2, and is also supported near the C-pillar assembly (a part of the C-pillar upper inner plate 7 belongs to the C-pillar assembly). It can be understood that based on the strong support of the reinforcement 4, the vehicle provided by this embodiment has good body stability and safety; and when designing the vehicle of this embodiment, the designer can also reduce the design quantity of other reinforcement plates (used to strengthen the C-pillar assembly and the D-pillar assembly 1), thereby indirectly reducing the weight of the vehicle body; further related to this, based on the reduction in the number of parts used to strengthen the overall structure of the vehicle, the visual space of the occupants at the rear of the vehicle can be improved to a certain extent, which is undoubtedly conducive to improving the riding experience of the occupants.

[0058] Please continue reading Figure 3The rear structure of the vehicle also includes a C-pillar lower inner plate 9; in a possible implementation manner, a reinforcing plate can be provided on the front side of the reinforcing member 4, and the reinforcing plate is fixedly connected to the reinforcing member 4, the C-pillar upper inner plate 7 and the wheel cover assembly 2.

[0059] Please refer back to Figure 1 and Figure 2 The rear structure of the vehicle of the present embodiment further comprises a seat 8, the seat 8 comprises a seat back 81 and a headrest 82, the aforementioned safety belt 6 is configured to be pulled to the front side of the seat back 81 via the retractor 3; based on this, in order to shorten the required distance of the safety belt 6 to the front side of the seat back 81, as Figure 2 and Figure 3 As shown, in this embodiment, the through opening 41 for allowing the safety belt 6 to enter and exit the reinforcement member 4 is specifically arranged in the middle and upper part of the first side wall 43 .

[0060] Please continue reading Figure 2 and Figure 3 Based on the fact that the retractor 3 is installed in the reinforcement 4, this embodiment also provides an approximately inverted trapezoidal assembly opening 421 on the main body 42; when installing the retractor 3, the worker can hold the retractor 3 through the assembly opening 421 and place the retractor 3 into the reinforcement 4, and then fix the retractor 3 to the first plate 5.

[0061] Based on the above, in order to ensure the installation stability of the retractor 3, the fixing details of the first plate 5 include:

[0062] like Figure 4 As shown, the first panel 5 includes a main body 51 and four extended ends which are connected as a whole; the four extended ends are respectively a first end 52, a second end 53, a third end 54 and a fourth end 55. The first panel 5, the first end 52, the second end 53, the third end 54 and the fourth end 55 are all special-shaped bodies. The first end 52 is located at the front of the first panel 5, and the third end 54 is located at the rear of the first panel 5. The second end 53 and the fourth end 55 are respectively extended from the main body 51 between the first end 52 and the second end 53 toward the outside of the main body 51, and the fourth end 55 is closer to the outside of the vehicle than the second end 53.

[0063] After the rear structure of the vehicle is assembled, Figure 4 and Figure 5 As shown, the first end portion 52 is located between the first side wall 43 and the C-pillar upper inner panel 7, and is welded to the upper end of the first side wall 43 and the C-pillar upper inner panel 7; the second end portion 53 is located between the main body 42 and the D-pillar upper inner panel 11, and is welded to the main body 42 and the D-pillar upper inner panel 11; the third end portion 54 is welded to the D-pillar upper inner panel 11; and the fourth end portion 55 is welded to the D-pillar upper inner panel 11 and the C-pillar upper inner panel 7. In this embodiment, in order to more clearly illustrate that the first end portion 52 is welded to the upper end of the first side wall 43 and the C-pillar upper inner panel 7, Figure 3 The solid arrow indicates the intersection of the three; to more clearly illustrate the second end 53 is welded to the main body 42 and the D-pillar upper inner plate 11, and also Figure 3 The dotted arrows in the figure indicate the overlap of these three.

[0064] It is understandable that, although the first plate 5 provided in this embodiment has the special-shaped structure as described above, for the first plate 5, under the premise of ensuring that it has sufficient installation stability, the technicians in this field can flexibly design its appearance according to their own needs. For example, the first plate 5 can be triangular, and its three corners are respectively welded to the main body 42, the first side wall 43 and the second side wall 44, but not directly connected to the aforementioned D-pillar assembly 1 and the C-pillar upper inner plate 7, so as to be mounted inside the reinforcement 4; for another example, the first plate 5 can be quadrangular, three of its four corners are respectively welded to the main body 42, the first side wall 43 and the second side wall 44, and the remaining one is directly connected to the C-pillar upper inner plate 7, so as to be mounted inside the reinforcement 4. In a possible embodiment, the design principle of the first plate 5 may be: the first plate 5 includes a main body 51 and at least two extended ends, the extended ends are extended from the main body 51 toward the outside of the main body 51, and among the at least two extended ends, at least one extended end is fixedly connected to the reinforcement 4, so that the first plate 5 can be erected inside the reinforcement 4 and connected to the reinforcement 4.

[0065] Please continue reading Figure 6 and Figure 7 To ensure the installation stability of the retractor 3, the fixing details between the retractor 3 and the first plate 5 include:

[0066] The retractor 3 is configured to be located at the lower side of the first plate 5 and fixedly connected to the first plate 5; a pre-hanging body I is provided on the retractor 3, and the pre-hanging body I is used to hook the main body 51, so that the retractor 3 can be pre-installed on the main body 51 before the fixing is completed. Specifically, the retractor 3 of this embodiment is provided with three pre-hanging bodies I, and the connection lines of the positions of the three pre-hanging bodies I form a triangle to ensure the stability of the retractor 3 when it is pre-installed on the main body 51; correspondingly, the main body 51 is provided with holes corresponding to the three pre-hanging bodies I.

[0067] Based on the above, a mounting hole 31 is further provided on the top of the retractor 3, and a first nut 13 is further welded on the upper surface of the main body 51, and a hole (not shown) is correspondingly provided at the welding position of the first nut 13, which passes through the main body 51 and is aligned with the first nut 13; illustratively, the mounting hole 31 is configured to be aligned with the aforementioned hole and the first nut 13 after the retractor 3 is pre-installed, so that a fixing member such as a bolt is subsequently passed through the first nut 13 and the mounting hole 31, so that the retractor 3 and the first plate 5 can be fixedly connected.

[0068] Please continue reading Figure 6 and Figure 7 To ensure that the safety belt 6 can be fully guided after the retractor 3 is fixedly connected to the first plate 5, the rear structure of the vehicle further exemplarily includes a first guide member 14, which is configured to be fixed on the first side wall 43 (i.e., located in front of the retractor 3), and is provided with a passage 141 for the safety belt 6 to enter and exit. When the safety belt 6 is released from the retractor 3, it will first pass through the passage 141 and then go to the seat 8; when the safety belt 6 is received in the retractor 3, it will first pass through the passage 141 and then enter the retractor 3.

[0069] Exemplarily, the first guide member 14 is a special-shaped body, and the lower part of the first guide member 14 is provided with the aforementioned passage 141, and the passage 141 is configured so that at least a portion of it is aligned with at least a portion of the through-opening 41 to achieve barrier-free entry and exit of the safety belt 6 into the reinforcement member 4; in addition, similar to the retractor 3, the upper part of the first guide member 14 is provided with two pre-hanging bodies I for enabling the first guide member 14 to be pre-installed on the first side wall 43; correspondingly, similar to the cooperation between the retractor 3 and the main body 51, the first side wall 43 is provided with holes corresponding to the two pre-hanging bodies I respectively; at the same time, a second nut 15 connected to the first side wall 43 is provided on the rear side of the first side wall 43. After the first guide member 14 is pre-installed, a fixing member such as a bolt is inserted into the first guide member 14 and the second nut 15, so that the first guide member 14 and the first side wall 43 can be fixedly connected.

[0070] Please refer to Figure 8 and Figure 1 To ensure that the seat belt 6 can be fully guided, the rear structure of the vehicle further exemplarily includes a second guide member 16, which is a ring-mounted part provided on the seat back 81 and located on the side of the headrest 82. The inner ring area of ​​the second guide member 16 forms a passage 161 for the seat belt 6 to pass through. When the seat belt 6 is released from the retractor 3, it will first pass through the passage 141 and then through the passage 161, and finally go to the front side of the seat back 81; when the seat belt 6 is received in the retractor 3, it will first pass through the passage 161, then pass through the passage 141, and finally enter the retractor 3.

[0071] Please continue reading Figure 8 and Figure 7 The inventor of this case found that the height difference between the through-hole 41 and the through-hole 161 in the vertical direction will significantly affect whether the safety belt 6 can be easily pulled out and used. Based on this, in this embodiment, by specially controlling the through-hole 161 and the through-hole 41 to have a reasonable relative position (or height difference), the portion of the safety belt 6 from the outlet of the retractor 3 to the upper side of the seat back 81 has a certain height difference. Figure 8On the contrary, if the height difference between the through-port 41 and the through-port 161 is too large, the safety belt 6 may have a relatively straight trend as shown in FIG. Figure 8 The direction shown by the middle dotted line is from bottom to top, approaching the seat back 81, then climbing to the upper side of the seat back 81 after an obvious bend, and then crossing the upper surface of the seat back 81 and turning down to the front side of the seat back 81; it is understandable that this direction of the safety belt 6 will make it more difficult to pull the safety belt 6.

[0072] In general, in a possible implementation, aligning at least a portion of the passage opening 161 with at least a portion of the through-opening 41 can make the safety belt 6 easier to pull out and use; or, making the height difference between the lower edge of the passage opening 161 and the upper edge of the through-opening 41 in the vertical direction within 35 mm can also make the safety belt 6 easier to pull out and use.

[0073] Please refer to Fig. 9 , Figure 1 and Figure 2 As mentioned above, the reinforcement 4 can strengthen the rear structure of the vehicle because it stands between the D-pillar assembly 1 and the wheel cover assembly 2; based on this, it should also be explained that since the reinforcement 4 is designed between the wheel cover assembly 2 and the D-pillar assembly 1, and the rear structure of the vehicle also includes the rear top cross beam II, the vehicle floor, the wheel cover assembly 2 located on the left side of the vehicle, the reinforcement 4 located on the left side of the vehicle, the D-pillar assembly 1 located on the left side of the vehicle, the rear top cross beam II, the D-pillar assembly 1 located on the right side of the vehicle, the reinforcement 4 located on the right side of the vehicle and the wheel cover assembly 2 located on the right side of the vehicle can be connected to form a ring structure at the rear of the vehicle (please also refer to the white arrow representing the transmission of force in the figure).

[0074] Based on the above ring structure, it can be seen that the vehicle of this embodiment has a high efficiency in force transmission; when the side panel vibrates at a high frequency, the force will be efficiently transmitted to the rear top cross beam II and the wheel cover assembly 2, and then the wheel cover assembly 2 and the rear top cross beam II, which can generate a large inertia, will constrain the vibration generated by the force, thereby suppressing the vibration. In order to more specifically reflect the effect of suppressing vibration, the inventor of this case conducted a vehicle road noise analysis on a vehicle designed according to this embodiment, and obtained the following results: Fig.10 The results shown. Fig.10 It can be seen that the vibration acceleration amplitude of the vehicle near 130HZ is 30mm / s 2 Around 0-150HZ, the maximum value of the acceleration amplitude is only around 50HZ.

[0075] Embodiment 2

[0076] like Fig.11 and Fig.12As shown, this embodiment generally provides a vehicle. Based on the design described in Embodiment 1, a second plate member 17 is additionally provided below the first plate member 5 and is mounted within the reinforcing member 4. The second plate member 17 is used to support the retractor 3 to ensure the stable installation of the retractor 3.

[0077] In this embodiment, the first plate member 5 and the second plate member 17 form a mounting plate; in other words, the rear structure of the vehicle in this embodiment further includes a mounting plate, which includes the first plate member 5 and the second plate member 17. The retractor 3 is located between the first plate member 5 and the second plate member 17, and the retractor 3 is located on the upper side of the second plate member 17 and is supported by the second plate member 17.

[0078] It can be understood that there may be a fixed connection point between the second plate member 17 and the retractor 3, or the second plate member 17 may only be in contact with the retractor 3 to support the retractor 3, which can be flexibly set by those skilled in the art. Similarly, like the first plate member 5, the shape of the second plate member 17 can also be flexibly set by those skilled in the art. For example, when viewing the second plate member 17 from top to bottom, the second plate member 17 can be a quadrilateral (see Fig.13 ), a triangle or other polygons.

[0079] It can also be understood that the connection relationship between the second plate member 17 and the reinforcing member 4 can refer to the possible connection relationships between the first plate member 5 and the reinforcing member 4 in Embodiment 1; in possible implementation manners, the second plate member 17 can only be mounted inside the reinforcing member 4 and welded to the reinforcing member 4; the second plate member 17 can also be mounted inside the reinforcing member 4 and welded to the reinforcing member 4, and also welded to the D-pillar assembly 1 and the upper inner panel 7 of the C-pillar.

[0080] It can also be understood that as described above, Embodiment 1 is equivalent to a design in which the mounting plate includes the first plate member 5 but does not include the second plate member 17. Based on this, from the perspective of realizing the installation of the retractor 3, it is easy to know that in possible implementation manners, the first plate member 5 can also be not provided on the basis of adopting the design of Embodiment 1, but only the second plate member 17 is used to support the retractor 3; at this time, the mounting plate includes the second plate member 17 but does not include the first plate member 5, and there is a fixed connection point between the retractor 3 and the second plate member 17.

[0081] It can be understood that when the mounting plate only includes one of the second plate member 17 and the first plate member 5, when looking from inside the vehicle to the outside of the vehicle, the reinforcing member 4 with the mounting plate has a structure of a Chinese character 'Ri'; and when the mounting plate includes the first plate member 5 and the second plate member 17, when looking from inside the vehicle to the outside of the vehicle, the reinforcing member 4 with the mounting plate has a structure of a Chinese character 'Mu'.

[0082] In summary, the utility model adopts an arrangement in which the reinforcement member 4 and the mounting plate are concentrated together. This arrangement can make the reinforcement member 4 and the first plate member 5 cooperate with each other, can improve the rigidity and torsional performance of the rear structure of the vehicle, and is conducive to the lightweight of the vehicle.

[0083] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
