Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a front enclosure support structure. Meanwhile, the utility model also relates to a vehicle provided with the front enclosure support structure. Background Art

[0002] There are usually two ways to connect the instrument panel reinforcement beam to the center channel. One is that the two center channel connection brackets on the left and right are fixed to the floor bracket, and the other is that only the left center channel bracket is connected to the floor bracket, and the right center channel bracket is suspended to provide a mounting point for the lower part of the instrument panel. At the same time, in order to ensure the overall strength, a straight-line connection bracket is generally added between the left and right center channel brackets. This connection bracket also provides 1 to 2 fastening points for the lower area of ​​the instrument panel. However, the existing center channel bracket has the problem of insufficient structural strength, which makes the overall structural strength of the instrument panel reinforcement beam support assembly weak and cannot meet the performance requirements of the whole vehicle.

[0023] In addition, the setting of the second bracket can make up for the problem that the support bracket is far from the installation point of the dashboard due to the vehicle shape and the surrounding structure layout, so as to improve the support effect on the dashboard. The left and right ends of the first bracket are connected at the corresponding first bending section, which can not only form an H-shaped structure with the left and right support brackets to improve the structural strength of the entire structure, but also enhance the structural strength of the left and right support brackets.

[0052] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0053] Embodiment 1

[0054] The present embodiment relates to a front enclosure support structure, which has good structural strength, can improve the supporting effect for the instrument panel 300, and take into account the installation and arrangement of peripheral components, thereby enhancing the structural performance of the entire vehicle.

[0055] In terms of overall structure, Figure 1 and Figure 2As shown, the front wall support structure of this embodiment includes a support bracket 11 arranged between the vehicle body floor 100 and the instrument panel reinforcement beam 200. The support bracket 11 is arched backward along the front-rear direction of the vehicle, and the support bracket 11 has a first bending section 11a, a second bending section 11b and a third bending section 11c arranged in sequence from top to bottom.

[0056] In addition, a first reinforcing bracket 12 is provided between the supporting bracket 11 and the instrument panel reinforcing beam 200, the upper end of the first reinforcing bracket 12 is connected to the instrument panel reinforcing beam 200, the lower end of the first reinforcing bracket 12 extends to the first bending section 11a, and the second reinforcing bracket 14 is connected to the second bending section 11b.

[0057] When implementing it, Figure 1 and Figure 5 As shown, the support bracket 11 of this embodiment also has a bottom connecting section 11d arranged at the bottom of the third bending section 11c, the bottom connecting section 11d is connected to the vehicle body floor 100 through the floor connecting frame 101, and the bottom connecting section 11d is provided with a floor connecting hole 117 for assembling with the floor connecting frame 101.

[0058] At the same time, the support bracket 11 of this embodiment can improve the structural strength of the support bracket 11 body based on its own backward arching along the front-to-rear direction of the vehicle, and then by providing the first reinforcing bracket 12 and the second reinforcing bracket 14, it can improve the structural strength of the first bending section 11a and the second bending section 11b, and compensate for the rigidity lost due to bending, thereby having higher structural strength and better supporting effect on the dashboard 300.

[0059] Based on the above overall introduction, specifically, in this embodiment, as a preferred implementation form, see Figure 3 and Figure 5 As shown, the support bracket 11 is provided with at least one of a first reinforcing rib 114 , a first harness mounting point and a first positioning structure, wherein the first positioning structure is used to position the support bracket 11 during assembly.

[0060] Here, by setting the first reinforcing rib 114, the structural strength of the support bracket 11 can be further improved. By setting the first wiring harness installation point, the support bracket 11 can also take into account the function of fixing the wiring harness and improve the space utilization rate at the front support structure. The setting of the first positioning structure is conducive to improving the assembly convenience of the support bracket 11.

[0061] Secondly, in this embodiment, as a preferred implementation form, the cross-section of the support bracket 11 is a "U" shape with one side open, and includes a base plate 111, and a first side plate 112 and a second side plate 113 respectively arranged on the front and rear sides of the base plate 111, and the first reinforcing bracket 12 is located inside the support bracket 11.

[0062] It can be understood that the cross-section of the support bracket 11 is U-shaped, which can have better structural strength. At the same time, the first reinforcing bracket 12 is arranged in the support bracket 11, which can play a better structural reinforcement role.

[0063] As a preferred implementation form, the support bracket 11 of this embodiment is provided with a first reinforcing rib 114 , a first wiring harness installation point and a first positioning structure to increase the functionality of the support bracket 11 and improve the practicability of the support bracket 11 .

[0064] In a specific implementation, based on the side of the second side panel 113 facing the dashboard 300, the first wiring harness mounting point can preferably be set as a plurality of first wiring harness mounting holes 115 provided on the second side panel 113, and the number and arrangement of the first wiring harness mounting holes 115 can be set and adjusted accordingly according to the actual wiring harness fixing needs. For example, a first wiring harness mounting hole 115 is respectively provided below the first bending section 11a and between the second bending section 11b and the third bending section 11c.

[0065] Similarly, the first positioning structure of this embodiment can be set and adjusted based on the bending and assembly (or welding) requirements of the support bracket 11. For example, the first positioning structure includes a plurality of first positioning holes 116 provided on the base plate 111 and the second side plate 113.

[0066] Furthermore, the first reinforcing ribs 114 of the present embodiment may preferably be arranged on the substrate 111, and the number and arrangement may also be set and adjusted according to actual structural reinforcement requirements. For example, the first reinforcing ribs 114 may be two or three arranged in sequence from top to bottom, or the first reinforcing ribs 114 may be arranged at the connection between the substrate 111 and the second side panel 113 and at the connection between the substrate 111 and the first side panel 112, etc.

[0067] The support bracket 11 of this embodiment is preferably formed by integral stamping, which is more conducive to improving the molding quality and achieving standardization. Moreover, based on the lightweight demand, additional weight-reducing holes can be provided, for example, in the area where the first reinforcing ribs 114 are arranged.

[0068] Moreover, the related structural parts not mentioned in the front wall support structure of this embodiment can refer to the parts of the common vehicle body structure in the prior art, for example, the instrument panel reinforcement beam 200 is usually a tube beam, etc. At the same time, in order to improve the connection strength with the instrument panel reinforcement beam 200, in the support bracket 11 of this embodiment, the first folding edge 1121 and the second folding edge 1131 that fit the instrument panel reinforcement beam 200 are respectively provided on the top of the first side plate 112 and the second side plate 113, and at the same time, the top of the base plate 111 is also provided with an arc connecting edge 1111 that matches the structural shape of the instrument panel reinforcement beam 200, etc.

[0069] In addition, in this embodiment, as a preferred implementation form, see Figure 6 and Figure 7 As shown, the first reinforcing bracket 12 includes a first bottom plate 121, a top flange 122 disposed on the top of the first bottom plate 121, and a front flange 123 and a rear flange 124 disposed on the front and rear sides of the first bottom plate 121.

[0070] In addition, the top flange 122 is connected to the instrument panel reinforcement beam 200, the front flange 123 is connected to the first side plate 112, and the rear flange 124 is connected to the second side plate 113. Based on the arrangement of the top flange 122, the front flange 123 and the rear flange 124, it is beneficial to increase the connection area between the first reinforcement bracket 12 and the instrument panel reinforcement beam 200 and between the support bracket 11 and the first reinforcement bracket 12, thereby improving the connection strength and reliability.

[0071] In a specific implementation, the rear flange 124 is formed by extending the rear edge of the first bottom plate 121 toward one side of the base plate 111 , and during installation, the rear flange 124 is fitted and connected to the second side plate 113 , thereby increasing the connection area between the two, improving the connection reliability and the structural reinforcement effect on the support bracket 11 .

[0072] Considering the requirements of structural strength, the first reinforcing bracket 12 of this embodiment is provided with a second reinforcing rib 1211 for increasing structural strength, and the second reinforcing rib 1211 is formed by the first bottom plate 121 being concave toward the side of the base plate 111. If necessary, the second reinforcing rib 1211 may be provided with a second positioning hole 1212 for molding and assembly, and a first weight-reducing hole 1213 for weight reduction.

[0073] In addition, in this embodiment, as a preferred implementation form, a third reinforcing bracket 13 is connected to the third bending section 11c. Fig.10 and Fig.11 As shown, the third reinforcing bracket 13 includes a third bottom plate 131 connected to the first side plate 112 and the second side plate 113 , a connecting plate 132 arranged on the third bottom plate 131 and extending toward a side away from the base plate 111 , and a mounting plate 133 arranged on the connecting plate 132 .

[0074] By setting the third reinforcing bracket 13, the structural strength of the third bending section 11c can be improved, and the coordinated setting of the mounting plate 133, the connecting plate 132 and the mounting plate 133 can make the third reinforcing bracket 13 visually roughly Z-shaped, so as to have better torsion resistance.

[0075] To elaborate, as a preferred implementation form, in this embodiment, a second harness mounting point is provided on the third bottom plate 131, and a first mounting point for mounting peripheral components is provided on the mounting plate 133. In this way, the third bracket can not only strengthen the structure, but also fix the harness and mount peripheral components, thereby improving the practicality and space utilization of the front wall support structure.

[0076] In a specific structure, the second harness mounting point can be set as a second harness mounting hole 1311 for fixing the harness, and the first mounting point can be set as a first mounting hole 1331 for mounting peripheral components. Furthermore, the first mounting hole 1331 can be used to be screwed to the mounting point of the auxiliary instrument panel 300, and in order to facilitate the screw connection between the two, a first projection welding nut 1332 corresponding to the first mounting hole 1331 is also provided on the mounting plate 133.

[0077] At the same time, in this embodiment, as a preferred implementation form, the upper and lower sides of the connecting plate 132 are provided with a first reinforcing flange 134 connected between the mounting plate 133 and the second side plate 113, which is beneficial to improve the structural strength of the third reinforcing bracket 13 itself.

[0078] In addition, in this embodiment, as a preferred implementation form, combined with Figure 8 and Fig. 9 As shown, a second mounting point for mounting peripheral components is provided on the second reinforcing bracket 14. Thus, the second reinforcing bracket 14 can also perform the function of mounting peripheral components at intervals, thereby improving its practicality and space utilization at the front wall support structure.

[0079] Specifically, the second reinforcing bracket 14 of the present embodiment includes a second base plate 141, the second base plate 141 has a connecting section 1411 connected to the first side plate 112 and the second side plate 113, and a bending section 1412 connected to the connecting section 1411 and provided with the above-mentioned second installation point, and the second installation point can preferably be an air conditioner installation hole 1415 for installing an air conditioner arranged on the bending section 1412.

[0080] If necessary, the first bottom plate 121 of this embodiment may also be provided with a third reinforcing rib 1416 for increasing structural strength, a third positioning hole 1413 for molding and installation, and a second weight-reducing hole 1414 for achieving lightweight design, and based on the needs of miniaturized design, the second weight-reducing hole 1414 may be located in the area of ​​the third reinforcing rib 1416. At the same time, the third reinforcing rib 1416 may preferably be formed on the connecting section 1411, and at the connection between the connecting section 1411 and the bending section 1412.

[0081] Furthermore, also as a preferred implementation form, in this embodiment, see Figure 1 and Fig.12 As shown, a fourth reinforcing bracket 15 is connected to the supporting bracket 11 , the fourth reinforcing bracket 15 is located below the third bending section 11 c , and a cavity is formed between the fourth reinforcing bracket 15 and the supporting bracket.

[0082] It can be understood that by forming a cavity between the fourth reinforcing bracket 15 and the supporting bracket 11, not only the structural strength of the supporting bracket 11 can be enhanced by the fourth reinforcing bracket 15 itself, but also the structural strength of the supporting bracket 11 can be enhanced by utilizing the large strength of the cavity structure.

[0083] In the specific structure, the fourth reinforcing bracket 15 of this embodiment can be preferably set to a U-shape. When installed, it is interlocked with the U-shaped supporting bracket 11 to enclose and form the above-mentioned cavity, and the fourth reinforcing bracket 15 is preferably arranged in the U-shaped area of ​​the supporting bracket 11.

[0084] The front enclosure support structure of the present embodiment can enhance the structural strength of the support bracket itself by making use of the strong characteristic of the arched structure, by arching the support bracket 11 rearward along the front-rear direction of the vehicle. At the same time, the first reinforcing bracket 12 and the second reinforcing bracket 14 are provided to enhance the connection strength between the support bracket 11 and the instrument panel reinforcing beam 200, as well as the structural strength at the first bending section 11a and the second bending section 11b, thereby making the support bracket 11 have good structural strength and supporting performance.

[0085] Embodiment 2

[0086] This embodiment relates to a vehicle, in which the front wall support structure of the first embodiment is provided. Fig.13 As shown, in this embodiment, as a preferred implementation form, there are two supporting brackets 11 arranged opposite to each other on the left and right, and a first bracket 31 is provided between the two supporting brackets 11 .

[0087] The first bracket 31 is provided with a second bracket 32 ​​connected to the instrument panel 300 , which can make up for the problem that the support bracket 11 is far away from the installation point of the instrument panel due to the vehicle shape and the surrounding structure layout, so as to improve the supporting effect of the instrument panel 300 .

[0088] It should be mentioned that the front wall support structure of this embodiment includes a left bracket and a right bracket, that is, the first bracket 31 is connected between the left bracket and the right bracket, and the left bracket and the right bracket both use the support bracket 11 in the first embodiment, and the only difference is that the U-shaped openings of the left and right support brackets (left bracket and right bracket) are opposite, so this embodiment is Figure 1 , Figure 2 , Fig.13 and Fig.14 Only the left bracket adopts the support bracket 11, and Fig.13The instrument panel 300 shown in FIG. 1 is specifically a lower portion of the instrument panel 300 .

[0089] At the same time, the left and right ends of the first bracket 31 are connected to the corresponding first bending section 11a, which can not only form an H-shaped structure between the support brackets 11 on the left and right sides to enhance the overall structural strength of the structure, but also enhance the structural strength of the support brackets 11 on the left and right sides.

[0090] Furthermore, as a preferred implementation form, the width of the support bracket 11 in the front-rear direction of the vehicle gradually decreases from top to bottom, thereby utilizing the gradual change in cross section to enhance the structural strength of the support bracket 11 itself, especially the strength after bending.

[0091] Secondly, in this embodiment, as a preferred implementation form, combined with Fig.13 and Fig.14 As shown, the middle part of the first bracket 31 arches backward along the front-rear direction of the vehicle, and a mounting platform is formed in the middle part of the first bracket 31, and the second bracket 32 ​​is provided with a left connecting arm 322a and a right connecting arm 322b extending to one side of the first bracket 31, and the left connecting arm 322a and the right connecting arm 322b are both connected to the mounting platform.

[0092] It can be understood that the middle part of the first bracket 31 arches backward along the front-to-rear direction of the vehicle, and the strength of the arched structure can be used to improve the structural strength of the first bracket 31 itself, and an installation platform is formed in the middle part of the first bracket 31, which is beneficial to the assembly between the first bracket 31 and the second bracket 32.

[0093] Furthermore, in this embodiment, as a preferred implementation form, the second bracket 32 ​​has a left extension arm 321 a and a right extension arm 321 b extending toward one side of the instrument panel, and the left extension arm 321 a and the right extension arm 321 b are both connected to the instrument panel 300 .

[0094] By setting the left extension arm 321a and the right extension arm 321b, they can cooperate with the left connecting arm 322a and the right connecting arm 322b to form an "H"-shaped structure, which not only makes the second bracket 32 ​​have better structural strength and is more suitable for installation requirements of the dashboard 300 at different distances, but also helps to reduce the weight of the second bracket 32.

[0095] Specifically, based on the setting of the extension arm, even if the installation point of the dashboard 300 is far away, the second bracket 32 ​​of the present embodiment can also meet the installation requirements of the dashboard 300, and the extension arm is provided in multiple numbers, which can provide multiple installation points, thereby helping to improve the installation stability of the dashboard 300. Furthermore, providing an extension arm instead of the second bracket 32 ​​extending as a whole toward the installation point of the dashboard 300 is also helpful in reducing the material and weight of the second bracket 32, thereby achieving weight reduction and cost reduction.

[0096] Based on the above overall introduction, specifically, in this embodiment, as a preferred implementation form, Fig.15 and Fig.16 As shown, the second bracket 32 ​​includes a bracket substrate 320 and a first connecting flange 323 provided on a side of the bracket substrate 320 facing the instrument panel 300 , and the first connecting flange 323 is located between the left extension arm 321 a and the right extension arm 321 b .

[0097] By providing the first connecting flange 323 between the left extension arm 321a and the right extension arm 321b, the structure can be simplified and the structural strength of the second bracket 32 ​​itself can be improved.

[0098] In the specific implementation, in this embodiment, as a preferred implementation form, combined with Fig.13 and Fig.16 As shown, the first connecting flange 323 is provided with a mounting portion for mounting the electrical device 400 and a positioning portion for positioning the electrical device 400 during installation.

[0099] The first connecting flange 323 is provided with a mounting portion, so that the electrical device 400 can be installed and arranged between the support brackets 11 on the left and right sides and the mounting points of the instrument panel 300, which is conducive to improving space utilization. In a specific structure, the mounting portion can be set as a mounting hole 3231 screwed with the electrical device 400, and the positioning portion can be set as a positioning hole 3232.

[0100] To improve the installation stability of the electrical device 400, two or more installation holes 3231 may be provided. Secondly, if necessary, the positioning portion may further include a projection welding nut provided on the first connection flange 323 corresponding to the installation hole 3231 to improve the convenience of disassembly and assembly.

[0101] It should be noted that the "H" shape of the present embodiment refers to the second bracket 32 ​​being roughly "H"-shaped in overall visual sense, and is not a strictly "H" shape. In specific implementation, the second bracket 32 ​​composed of the left connecting arm 322a, the right connecting arm 322b, the bracket base plate 320, the left extension arm 321a and the right extension arm 321b also has a shape that is easy to match and install with the first bracket 31, the instrument panel 300, the electrical device 400 and surrounding components.

[0102] Furthermore, in this embodiment, as a preferred implementation form, Fig.15 As shown, a second reinforcing flange 324 is provided on the side of the bracket substrate 320 away from the first connecting flange 323 . Meanwhile, a reinforcing rib 325 is provided on the second bracket 32 ​​. The reinforcing rib 325 is located at the connection between the bracket substrate 320 and the first connecting flange 323 .

[0103] The advantage of such a configuration is that the structural strength of the second bracket 32 ​​can be improved, thereby improving the supporting effect on the instrument panel 300. In specific implementation, the second reinforcing flange 324 and the first connecting flange 323 are located on the same side of the bracket substrate 320, so that the cross section of the bracket substrate 320 is U-shaped, which is more conducive to improving the structural strength.

[0104] In addition, in this embodiment, as a preferred implementation form, a second connecting flange 3211 is provided on the left extension arm 321a and the right extension arm 321b, and each second connecting flange 3211 is provided with a connecting portion and a pre-positioning portion, wherein the connecting portion is used to connect to the instrument panel 300, and the pre-positioning portion is used to position the second connecting flange 3211 during connection.

[0105] It can be understood that the left extension arm 321a and the right extension arm 321b are both provided with a second connecting flange 3211, which can improve the connection reliability between the two and the instrument panel 300. At the same time, the coordinated arrangement of the connecting part and the pre-positioning part is conducive to improving the convenience of disassembly and assembly between each second connecting flange 3211 and the instrument panel 300.

[0106] Of course, in specific implementation, the connecting portion of this embodiment can be specifically a connecting hole 3212 set on the second connecting flange 3211, and the connecting hole 3212 is screwed to the instrument panel 300; the pre-positioning portion can be set as a pre-positioning hole 3213, and the structural shape of the pre-positioning hole 3213 can be set and adjusted according to actual positioning requirements, for example, it can be specifically a rectangle.

[0107] Moreover, in this embodiment, as a preferred implementation form, the second bracket 32 ​​is integrally stamped and formed, which is beneficial to the overall forming and quality control of the second bracket 32 ​​and realizes standardization. In the specific structure, the bracket substrate 320 of the second bracket 32 ​​is also provided with a forming positioning hole 3200 for mold positioning, so as to facilitate the stamping of the second bracket 32.

[0108] At the same time, as a preferred implementation form, in this embodiment, a third weight-reducing hole 326 is provided on at least one of the left connecting arm 322a, the right connecting arm 322b, the left extension arm 321a and the right extension arm 321b to facilitate further weight-reducing design of the second bracket 32.

[0109] In specific implementation, in order to achieve a lightweight design, the left connecting arm 322a, the right connecting arm 322b, the left extension arm 321a and the right extension arm 321b of this embodiment are all provided with a third weight-reducing hole 326, and the shape and size of the third weight-reducing hole 326 can be set and adjusted accordingly according to the actual weight-reduction requirements and the structural design requirements of the second bracket 32, for example, set to a round hole or a waist hole.

[0110] Considering the overall structural strength requirements of the second bracket 32, the cross-sections of the left connecting arm 322a, the right connecting arm 322b, the left extension arm 321a and the right extension arm 321b can preferably be set to the same U-shape as the bracket substrate 320 to further enhance the structural stability of the bracket.

[0111] In addition, based on the setting of the installation platform, in this embodiment, Fig.15 As shown, to facilitate the installation of the left connecting arm 322a and the right connecting arm 322b, as a preferred implementation, a connecting arm positioning hole 315 can also be set on the installation platform, and the left connecting arm 322a and the right connecting arm 322b correspond to one connecting arm positioning hole 315 respectively.

[0112] To elaborate, in this embodiment, as a preferred implementation form, both left and right ends of the first bracket 31 are provided with mounting arms 312 extending forward along the front-rear direction of the vehicle, and the mounting arm 312 at the left end is connected to the left support bracket 11, and the mounting arm 312 at the right end is connected to the right support bracket 11. Thus, it is beneficial to increase the connection area between the first bracket 31 and the left and right support brackets 11, and improve the connection stability.

[0113] In the specific implementation, in this embodiment, as a preferred implementation form, Fig.17 As shown, the first bracket 31 includes a bracket bottom plate 311, and the upper and lower edges of the bracket bottom plate 311 are both provided with third reinforcing flanges 313. Such a configuration makes the cross section of the first bracket 31 substantially U-shaped, which is beneficial to improving the overall structural strength.

[0114] And as a preferred implementation form, a fourth weight-reducing hole 314 is provided on the bracket bottom plate 311 to facilitate the weight-reducing design of the first bracket 31. At the same time, a wiring harness installation point is provided on the third reinforcing flange 313 located at the upper edge to improve space utilization. In the specific structure, the wiring harness installation point can be a third wiring harness installation hole 3131 for fixing the wiring harness, which is provided on the third reinforcing flange 313 located at the upper edge.

[0115] Of course, the mounting arm 312 of this embodiment can be formed by bending the two ends of the bracket bottom plate 311 and the third reinforcing flanges 313 at the upper and lower edges, so that the mounting arm 312 also has good structural strength. If necessary, the first bracket 31 of this embodiment can also be integrally stamped like the second bracket 32 ​​to ensure better molding quality and structural strength.

[0116] In this embodiment, by cooperating with the second bracket 32 ​​on the first bracket 31, and the second bracket 32 ​​is provided with an extension arm for connecting to the dashboard 300, on the basis of facilitating the realization of weight reduction design, it can also make up for the problem that the left and right side support brackets 11 and the installation points of the dashboard 300 are far away due to the vehicle shape and the surrounding structure layout, provide multiple installation points for the dashboard 300, and enhance the supporting effect of the dashboard 300, thereby making the dashboard 300 have better structural stability.

[0117] The vehicle of this embodiment, by providing the front enclosure support structure in the first embodiment, can provide good support for the instrument panel 300 and enhance the overall structural strength of the front part of the vehicle body, thereby enhancing the performance of the entire vehicle and providing a better user experience and market competitiveness.
