Description

Technical Field

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

[0002] The instrument panel reinforcement tube beam is usually connected to the center channel in two ways. One is that the two left and right center channel connection brackets 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, when the existing center channel bracket adopts a tubular structure similar to the instrument panel reinforcement tube beam, there is a problem of insufficient connection strength between the two, which makes the overall strength of the front support structure weak and cannot meet the performance requirements of the vehicle. Utility Model Content

[0003] In view of this, the utility model aims to provide a front enclosure support structure with better structural strength and support performance.

[0004] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0005] A front wall support structure comprises a support tube arranged between a vehicle body floor and a reinforcing tube beam of an instrument panel, and an upper connecting bracket arranged between the support tube and the reinforcing tube beam of the instrument panel;

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] The front enclosure support structure described in the utility model is provided with a U-shaped upper connecting bracket, and the top of the supporting tube is connected inside the upper connecting bracket, which can increase the contact area between the supporting tube and the upper connecting bracket and ensure the reliability of the connection between the two. At the same time, the top of the upper connecting bracket is provided with a tube beam connecting part that matches the outer contour of the instrument panel reinforcement tube beam, which can increase the connection length and reliability between the upper connecting bracket and the instrument panel reinforcement tube beam, thereby improving the connection strength between the supporting tube and the instrument panel reinforcement tube beam, so that the front enclosure support structure has better structural strength and supporting performance for the instrument panel.

[0015] Secondly, by providing an upper connection portion that matches the outer contour of the support tube, the contact area and connection reliability between the lower connection bracket and the support tube are improved, and the provision of the lower connection plate facilitates the connection of the lower connection bracket to the vehicle body floor. By providing a reinforced flange, the structural strength of the lower connection plate can be enhanced. The angle formed between the upper connection portion and the lower connection plate is between 120-140°, which can play a good role in connecting the support tube and the vehicle body floor, and is conducive to improving the overall structural strength of the front support structure. The overlap length between the floor connection frame and the vehicle body floor is not less than 25mm, which can ensure that there is sufficient connection length between the two, thereby ensuring connection reliability.

[0016] In addition, the bending angle of the second bending section is between 130-145°, which is conducive to forming and obtaining relatively good structural strength. The connection length between the lower plate connection section and the upper connection portion is not less than 30 mm, which is conducive to improving the connection reliability between the support tube and the lower connection bracket. The setting of the weight-reducing hole is conducive to the lightweight design of the upper connection bracket, and the edge of the weight-reducing hole is provided with a weld bead, which is conducive to increasing the welding length between the upper connection bracket and the support tube, thereby improving the connection reliability between the two.

[0017] Another object of the present invention is to provide a vehicle, wherein the vehicle is provided with the front enclosure support structure as described above.

[0018] Furthermore, the vehicle is provided with a support bracket arranged opposite to the support tube on the left and right; the support bracket arches backward along the front-to-back direction of the vehicle, and the support bracket has a first bending section, a second bending section and a third bending section arranged in sequence from top to bottom; a first reinforcement bracket is provided between the support bracket and the instrument panel reinforcement tube beam, a second reinforcement bracket is connected to the second bending section, and a third reinforcement bracket is connected to the third bending section.

[0021] Furthermore, a fourth reinforcing bracket is connected to the supporting bracket, the fourth reinforcing bracket is located below the third bending section, and a cavity is formed between the fourth reinforcing bracket and the supporting bracket.

[0022] Furthermore, a first bracket is provided between the supporting bracket and the supporting tube; a second bracket connected to the instrument panel is provided on the first bracket, and / or one end of the first bracket is connected to the first bending section of the supporting bracket, and the other end of the first bracket is connected to the supporting tube.

[0023] The vehicle described in the utility model is provided with the front enclosure support structure as described above, which can have good structural strength, effectively support the instrument panel, and help improve the structural performance of the front part of the whole vehicle, thereby improving the quality of the whole vehicle.

[0024] In addition, by arching the support bracket backward along the front-to-rear direction of the vehicle, the strong strength of the arched structure can be used to improve the structural strength of the bracket itself. At the same time, by setting the first reinforcing bracket, the second reinforcing bracket and the third reinforcing bracket, the structural strength of the first bending section, the second bending section and the third bending section can be enhanced to compensate for the stiffness lost due to bending, thereby making the support bracket have good structural strength and supporting performance.

[0025] In addition, the upper end of the first reinforcement bracket is connected to the instrument panel reinforcement tube beam, and the lower end of the first reinforcement bracket extends to the first bending section, which is conducive to improving the structural strength of the support bracket and the connection strength between the support bracket and the instrument panel reinforcement tube beam. The second reinforcement bracket and the third reinforcement bracket are both provided with mounting points for mounting peripheral components, which can take into account the function of mounting peripheral components, improve practicality and space utilization at the front wall support structure.

[0026] At the same time, the setting of the second harness mounting point enables the third bracket to not only strengthen the structure, but also take into account the function of fixing the harness, thereby improving practicality and space utilization at the front support structure. The setting of the first reinforcement flange further improves the structural strength of the third reinforcement bracket itself. The cavity formed between the fourth reinforcement bracket and the support bracket can further enhance the structural strength of the support bracket.

[0027] In addition, the second bracket can make up for the problem that the support bracket and the instrument panel installation point are far apart due to the vehicle shape and the surrounding structure layout, so as to improve the support effect on the instrument panel. The first bracket is connected at the first bending section, which can not only form an H-shaped structure with the support bracket and the support tube to improve the structural strength of the entire structure, but also enhance the structural strength of the support bracket and the support tube.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0063] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0064] Embodiment 1

[0065] The present embodiment relates to a front enclosure support structure, which has better structural stability and can enhance the support effect on the instrument panel 300, thereby improving the quality of the entire vehicle.

[0066] In terms of overall structure, Figure 1 and Figure 2 As shown, the dash support structure of this embodiment includes a support tube 21 disposed between the vehicle body floor 100 and the instrument panel reinforcement tube beam 200 , and an upper connection bracket 22 disposed between the support tube 21 and the instrument panel reinforcement tube beam 200 .

[0067] In addition, the upper connecting bracket 22 is U-shaped, the top of the support tube 21 is connected to the upper connecting bracket 22, and the top of the upper connecting bracket 22 has a tube beam connecting portion 221 that is matched with the outer contour of the instrument panel reinforcement tube beam 200, and the tube beam connecting portion 221 is connected to the instrument panel reinforcement tube beam 200.

[0068] It is worth mentioning that in the conventional technology, the support tube 21 and the instrument panel reinforcement tube beam 200 are usually welded in a butt joint state. Since a lap joint structure cannot be formed, the welding length and welding area are relatively small, resulting in a problem of low connection strength, which makes the overall stability of the structure insufficient. In this embodiment, an upper connecting bracket 22 is used to solve this problem.

[0069] It can be understood that the tube beam connection portion 221 of the present embodiment can increase the welding length and area between the upper connection bracket 22 and the instrument panel reinforcement tube beam 200, thereby enhancing the connection strength between the two. At the same time, the support tube 21 is connected in the U-shaped upper connection bracket 22, which can also improve the connection strength between the support tube 21 and the upper connection, thereby ensuring that there is sufficient connection strength between the support tube 21 and the instrument panel reinforcement tube beam 200.

[0070] Based on the above overall introduction, specifically, in this embodiment, as a preferred implementation form, see Figure 3 , Figure 5 and Figure 6 As shown, a weight-reducing hole is provided on the upper connecting bracket 22 , and a weld 2221 is provided at the edge of the weight-reducing hole for connecting the upper connecting bracket 22 and the supporting tube 21 .

[0071] The provision of the weight-reducing hole facilitates the lightweight design of the upper connecting bracket 22, and the edge of the weight-reducing hole is provided with a weld bead 2221, which is conducive to increasing the welding length between the upper connecting bracket 22 and the support tube 21, thereby improving the connection reliability between the two. Here, in order to facilitate the distinction from the weight-reducing holes described below, the weight-reducing hole on the upper connecting bracket 22 is referred to as the upper bracket weight-reducing hole 222.

[0072] Meanwhile, in this embodiment, as a preferred implementation form, the tube beam connection part 221 is welded to the instrument panel reinforcement tube beam 200. In this way, the connection reliability between the upper connection bracket 22 and the instrument panel reinforcement tube beam 200 can be ensured, and the process is mature and the operation is simple.

[0073] In addition, in this embodiment, as a preferred implementation form, see Figure 2 , Figure 3 and Figure 7 As shown, a lower connecting bracket 23 is provided between the support tube 21 and the vehicle body floor 100. The lower connecting bracket 23 has an upper connecting portion 231 matched with the outer contour of the support tube 21, and a lower connecting plate 232 connected to the upper connecting portion 231, the upper connecting portion 231 is connected to the support tube 21, and the lower connecting plate 232 is connected to the vehicle body floor 100.

[0074] It is understandable that by providing an upper connecting portion 231 that matches the outer contour of the support tube 21, the contact area and connection reliability between the lower connecting bracket 23 and the support tube 21 are improved, and the provision of the lower connecting plate 232 facilitates the connection between the lower connecting bracket 23 and the vehicle body floor 100.

[0075] In this embodiment, as a preferred implementation form, combined with Figure 7 and Figure 8 As shown, the lower connecting plate 232 is provided with a reinforcing flange at its edge to enhance the structural strength of the lower connecting plate 232. Here, in order to distinguish it from the reinforcing flanges described below, the reinforcing flange on the lower connecting plate 232 is referred to as the lower plate reinforcing flange 233.

[0076] At the same time, as a preferred implementation form, Figure 4 As shown, the angle α formed between the upper connecting portion 231 and the lower connecting plate 232 of this embodiment is between 120-140°, and can be specifically 120°, 130° or 140°.

[0077] The advantage of such a configuration is that it can provide a good connection between the support tube 21 and the vehicle body floor 100 , thereby helping to improve the overall structural strength of the front enclosure support structure.

[0078] Furthermore, in this embodiment, as a preferred implementation form, the lower connecting bracket 23 is overlapped on the vehicle body floor 100 through the floor connecting frame 101, and the overlapping length between the floor connecting frame 101 and the vehicle body floor 100 is not less than 25 mm. Thus, the floor connecting frame 101 and the vehicle body floor 100 can have a sufficient connection length, thereby ensuring the connection reliability between the two.

[0079] In specific implementation, the overlap length between the floor connecting frame 101 and the vehicle body floor 100 can be preferably set to 25mm, 28mm or 30mm, etc., so as to ensure the connection strength between the two while saving materials and facilitating lightness. If necessary, the lower connecting plate 232 of this embodiment can be provided with an assembly hole 234 for assembly with the floor connecting frame 101.

[0080] In addition, in this embodiment, as a preferred implementation form, Figure 4 As shown, the support tube 21 is arched backward along the front-rear direction of the vehicle, and the support tube 21 has a first bending section 21a and a second bending section 21b arranged in sequence from top to bottom, and the bending angle β of the second bending section 21b is between 130-145°.

[0081] Here, the support tube 21 is arched backward along the front-rear direction of the vehicle, and the structural strength of the support tube 21 itself can be improved by utilizing the high strength of the arched structure. At the same time, the bending angle β of the second bending section 21b is between 130-145°, which is conducive to molding and at least makes the second bending section 21b have relatively better structural strength.

[0082] Secondly, see Figure 2 and Figure 3 As shown, in this embodiment, as a preferred implementation form, the support tube 21 has a lower plate connecting section 21c located below the second bending section 21b, the lower plate connecting section 21c is connected to the upper connecting portion 231, and the connection length between the lower plate connecting section 21c and the upper connecting portion 231 is not less than 30 mm, so as to improve the connection reliability between the support tube and the lower connecting bracket.

[0083] Of course, in specific implementation, the bending angle β of the second bending section 21b can be specifically set to 130°, 140° or 145°, so that the support tube 21 is easy to shape and has better structural strength. At the same time, the connection length between the lower plate connecting section 21c and the upper connecting portion 231 can be specifically set to 30mm, 35mm or 38mm, etc., so as to reduce the material consumption while ensuring the reliability of the connection between the two, and realize cost reduction and weight reduction design.

[0084] At the same time, the relevant structural parts not mentioned in the front support structure of this embodiment can all refer to the various structures of common vehicle bodies in the prior art. For example, the support tube 21 is also provided with a side bracket 24, and the side bracket 24 is provided with a side connecting hole 241 for connecting with surrounding components.

[0085] The front enclosure support structure of the present embodiment is provided with a U-shaped upper connecting bracket 22, and the top of the support tube 21 is connected inside the upper connecting bracket 22, which can increase the contact area between the support tube 21 and the upper connecting bracket 22 and ensure the reliability of the connection between the two. At the same time, the top of the upper connecting bracket 22 is provided with a tube beam connecting portion 221 that matches the outer contour of the instrument panel reinforcement tube beam 200, which can increase the connection length and reliability between the upper connecting bracket 22 and the instrument panel reinforcement tube beam 200, thereby improving the connection strength between the support tube 21 and the instrument panel reinforcement tube beam 200, so that the front enclosure support structure has better structural strength and support performance for the instrument panel 300.

[0086] Embodiment 2

[0087] This embodiment relates to a vehicle, in which the front wall support structure of the first embodiment is provided. Figure 1 , Figure 2 and Fig. 20 As shown, as a preferred implementation form, in this embodiment, a support bracket 11 arranged opposite to the support tube 21 on the left and right is provided in the vehicle.

[0088] It should be mentioned that, in this embodiment Fig. 20 The instrument panel 300 shown is specifically the lower part of the instrument panel 300 , and in this embodiment, the supporting bracket 11 is located on the left side of the supporting tube 21 as an example for specific description.

[0089] The support bracket 11 is arched backward along the front-rear direction of the vehicle, and has a first bending section 11a, a second bending section 11b and a third bending section 11c arranged in sequence from top to bottom. In addition, a first reinforcement bracket 12 is arranged between the support bracket 11 and the instrument panel reinforcement pipe beam 200, a second reinforcement bracket 14 is connected to the second bending section 11b, and a third reinforcement bracket 13 is connected to the third bending section 11c.

[0090] When implementing it, Figure 1 and Fig.12 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.

[0091] 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, the second reinforcing bracket 14 and the third reinforcing bracket 13, the structural strength of the first bending section 11a, the second bending section 11b and the third bending section 11c can be improved to compensate for the stiffness lost due to bending, thereby having higher structural strength and better supporting effect on the dashboard 300.

[0092] Based on the above overall introduction, specifically, in this embodiment, as a preferred implementation form, see Fig.10 and Fig.12 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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 .

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] At the same time, in order to improve the connection strength with the instrument panel reinforcement pipe beam 200, see Fig.11 As shown, in the support bracket 11 of this embodiment, a first folded edge 1121 and a second folded edge 1131 which are fitted with the instrument panel reinforcement tube beam 200 are respectively provided on the top of the first side panel 112 and the second side panel 113.

[0103] See also Fig.13 and Fig.14 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.

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 tube beam 200 and between the support bracket 11 and the first reinforcement bracket 12, thereby improving the connection strength and reliability.

[0105] 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 .

[0106] 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.

[0108] 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.

[0109] 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 13, in addition to the structural reinforcement function, can also take into account the functions of fixing the harness and mounting peripheral components, thereby improving practicality and space utilization at the front wall support structure.

[0110] 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.

[0111] 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.

[0112] In addition, in this embodiment, as a preferred implementation form, combined with Fig.15 and Fig.16 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.

[0113] Specifically, the second reinforcing bracket 14 of the present embodiment includes a second bottom plate 141 in a bent shape, the second bottom plate 141 has a connecting section 1411 connected to both the first side plate 112 and the second side plate 113, and an extending section 1412 connected to the connecting section 1411 and provided with the above-mentioned second mounting point, and the second mounting point may preferably be an air conditioner mounting hole 1415 for installing an air conditioner arranged on the extending section 1412.

[0114] 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 extending section 1412.

[0115] Furthermore, also as a preferred implementation form, in this embodiment, see Figure 1 and Fig.19 As shown, the supporting bracket 11 is connected to a fourth reinforcing bracket 15 , the fourth reinforcing bracket 15 is located below the third bending section 11 c , and the enclosure between the fourth reinforcing bracket 15 and the supporting bracket forms a cavity.

[0116] 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.

[0117] 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.

[0118] See also Fig. 20As shown, in this embodiment, as a preferred implementation form, a first bracket 31 is provided between the support bracket 11 and the support tube 21. A second bracket 32 ​​connected to the instrument panel 300 is provided on the first bracket 31, which can make up for the problem that the support bracket 11 is far from the installation point of the instrument panel due to the vehicle shape and the surrounding structure layout, so as to improve the support effect on the instrument panel 300.

[0119] At the same time, as a preferred implementation form, one end of the first bracket 31 is connected to the first bending section 11 a of the support bracket 11 , and the other end of the first bracket 31 is connected to the support tube 21 .

[0120] The advantage of such a configuration is that it can not only form an H-shaped structure between the support bracket 11 and the support tube 21 to improve the structural strength of the entire structure, but also can enhance the structural strength of the support bracket 11 and the support tube 21.

[0121] In specific implementation, based on the present embodiment, the support tube 21 also has a bending structure similar to the support bracket 11 , and the other end of the first bracket 31 is connected to the first bending section 21a of the support tube 21 to further enhance the structural strength of the support tube 21 .

[0123] 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.

[0124] 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 .

[0125] 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.

[0126] 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.

[0127] In addition, in this embodiment, as a preferred implementation form, Fig. 22 and Fig.23 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 .

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.

[0132] 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.

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 .

[0134] 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.

[0135] 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.

[0136] 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.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] In addition, based on the setting of the installation platform, in this embodiment, Fig. 22 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.

[0143] 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 support bracket 11, and the mounting arm 312 at the right end is connected to the support tube 21. Thus, it is beneficial to increase the connection area between the first bracket 31 and the support bracket 11 and the support tube 21, and improve the connection stability.

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.

[0146] 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.
