[0034] (3) compared with the installation mode of bolt or screw assembly, the installation support 3 which extends into the installation cavity 4 is arranged on the instrument panel reinforcing beam body 2, then the elastic protrusion 311 on the elastic sheet 31 of the installation support 3 and the clamping hole 412 arranged on the installation cavity 4 are elastically clamped, the assembly of the instrument panel framework body 1 and the instrument panel reinforcing beam is realized, the assembly structure is simple and convenient to install, the self-adapting, self-adjusting and self-energy releasing abilities of the elastic sheet 31 are used, the self-adjusting ability of vibration adjustment is used in the process of long-term driving vibration of the vehicle, and the risk of separation of the installation point is not easy to occur.

[0035] (4) the installation cavity 4 has the limiting effect on the installation support 3 which extends into the installation cavity 4, the close clamping of the elastic protrusion 311 on the elastic sheet 31 and the clamping hole 412 is realized by limiting the installation support 3 in the installation cavity 4, and the risk of separation is not easy to occur.

[0036] (5) the assembly mode of the elastic sheet 31 and the clamping hole 412 is adopted, the installation support 3 is inserted into the installation cavity 4 during assembly, the elastic protrusion 311 on the elastic sheet 31 is elastically deformed under the pressure of the side wall of the installation cavity 4 when the installation support 3 is inserted into the installation cavity 4, the elastic force is released when the clamping hole 412 is encountered, the clamping hole 412 is clamped into the clamping hole 412, quick installation and disassembly are realized, the installation is simple and convenient, and the maintenance of the bearing parts is facilitated.

[0037] Need to explain, generally instrument panel skeleton body 1 both sides are fixedly connected with instrument panel reinforcement beam body 2, in actual application, this installation mode of setting installation cavity 4 cooperates with elastic sheet 31 clamping can be applied only on the left side or right side of instrument panel skeleton body 1, that is, only one side uses the structure of the present application, or left side and right side are used simultaneously, or translation or symmetry to other positions of the connection between instrument panel skeleton body 1 and instrument panel reinforcement beam body 2.

[0038] Regarding the shape of the installation cavity 4, it can only have a first side wall 41 and a second side wall 42; it can also only have an entrance closed cavity for the installation bracket 3 to extend into, of course, it should have two opposite side walls to limit the left and right orientation of the installation bracket 3; the clamping of the elastic protrusion 311 and the clamping hole 412 can realize the limitation of the front and back and up and down directions of the instrument panel skeleton body 1 and the instrument panel reinforcement beam body 2, thereby realizing the firmness of the clamping of the two.

[0039] The elastic sheet 31 involved in the present application can be a suspended elastic sheet 31 having only one connection point with the instrument panel skeleton body 1; it can also be that the opposite ends of the elastic sheet 31 are connected with the instrument panel reinforcement beam body 2, and the elastic protrusion 311 needs to have an arch-shaped protrusion to ensure that the elastic protrusion 311 elastically deforms when it is pressed.

[0040] In some embodiments, referring to Figure 4 , Figure 5 and Figure 9 , the installation bracket 3 has a support flange 32 extending in the opposite direction of the clamping direction of the elastic protrusion 311; when the elastic protrusion 311 is clamped in the clamping hole 412, the support flange 32 abuts on the second side wall 42 opposite to the first side wall 41 in the installation cavity 4, so that the installation bracket 3 is attached to the first side wall 41, and the elastic protrusion 311 is locked.

[0041] The instrument panel reinforcement beam body 2 is supported between the opposite two side walls of the installation cavity 4 by the support flange 32, which can make the large surface of the installation bracket 3 seamlessly attached to the first side wall 41, and lock the position of the elastic protrusion 311 in the left and right directions of the vehicle body, thereby locking the elastic protrusion 311 on the elastic sheet 31 and the clamping hole 412, ensuring the firmness of the connection between the instrument panel skeleton body 1 and the instrument panel reinforcement beam body 2, and avoiding the risk of the elastic protrusion 311 coming out of the clamping hole 412 due to bumps and vibrations during driving.

[0042] Secondly, the structure of the support flange 32 of the instrument panel reinforcement beam body 2 can also improve the rigidity of the structure of the instrument panel reinforcement beam body 2 itself, thereby improving the anti-deformation ability of the installation position of the instrument panel skeleton body 1 and the instrument panel reinforcement beam body 2, further improving the firmness after the assembly of the two, and ensuring the stable operation of the instrument panel and internal electrical devices relying on it.

[0043] Optionally, the two opposite edges of the mounting bracket 3 are provided with support flanges 32, so as to ensure that the mounting bracket 3 is closely attached to the first side wall 41 of the mounting cavity 4, so as to lock the elastic protrusion 311 with the clamping hole 412, and prevent the elastic protrusion 311 from being separated from the clamping hole 412.

[0044] In some embodiments, referring to Figure 7 As shown, the surface of the elastic protrusion 311 constitutes a conical surface abutting the clamping hole 412, and the corresponding clamping hole 412 is a square hole, so as to facilitate the abutment of the conical surface of the elastic protrusion 311 and the clamping hole 412, so as to realize the positioning reliability in the front-rear direction and the up-down direction between the two, and improve the firmness of the clamping between the two. The guide angle α between the generatrix of the conical surface and the first side wall 41 is 45°-60°, so that the elastic protrusion 311 has a certain protrusion height, which can ensure that the elastic protrusion 311 is clamped into the clamping hole 412 to a certain depth, thereby ensuring the firmness of the clamping between the two. If the angle α is too small, the height of the elastic protrusion 311 is small, which is commonly referred to as the slope formed is small, and the clamping between the elastic protrusion 311 and the clamping hole 412 is not firm. If the angle α is too large, the height of the elastic protrusion 311 is too large, and it is not easy to clamp into the clamping hole 412. At the same time, in order to improve the firmness of the clamping between the elastic protrusion 311 and the clamping hole 412, the clamping depth L of the elastic protrusion 311 extending into the clamping hole 412 is greater than 1 / 3 of the thickness of the first side wall 41.

[0045] In combination Figure 7 It is understood that the clamping degree of the elastic protrusion 311 and the clamping hole 412 is related to the guide angle α, the clamping depth L, the clamping width s of the clamping hole 412, and the thickness t of the mounting bracket 3, which can be adjusted according to the thickness t, material and process requirements of the mounting bracket 3. The greater the guide angle α, the higher the height of the elastic protrusion 311, and the greater the installation operation force; the deeper the clamping depth L, the greater the assembly process operation force; the thicker the thickness t of the mounting bracket 3, the greater the clamping width s required; but the overall assembly principle must ensure that the elastic sheet 31 is deformed under pressure during the installation process, and after assembly, the support flange 32 is closely attached to the second side wall 42 of the mounting cavity 4, and the mounting bracket 3 can be filled with the mounting cavity 4, and the elastic sheet 31 is elastically abutted to the first side wall 41, and the elastic protrusion 311 is locked in the clamping hole 412, thereby fixing the instrument panel framework body 1 and the instrument panel beam body 2.

[0046] The selection examples of these parameters in the present application are as follows: the guide angle α is 45°, the clamping depth L=2mm, the clamping width s=7mm, and the thickness t of the mounting bracket 3 is 1.2mm; the guide angle α is 55°, the clamping depth L=3mm, the clamping width s=8mm, and the thickness t is 1.5mm.

[0047] According to the needs of different models, by adjusting the parameter values ​​of α, L, s and t, the solution can be changed to obtain different clamping effects.

[0048] In some embodiments, see Figure 7 The height of the elastic protrusion 311 is greater than the thickness of the mounting bracket 3. The elastic protrusion 311 must not only ensure a certain engaging depth, but also the height of the elastic protrusion 311 must be greater than the thickness of the mounting bracket 3. The elastic protrusion 311 is formed into an arc-shaped shape to ensure sufficient elastic deformation ability of the elastic protrusion 311. Of course, the mounting bracket 3 of the present application is tightly fitted with the first side wall 41. In theory, the elastic protrusion 311 can be completely engaged with the engaging hole 412. At this time, the engaging depth is consistent with the height of the elastic protrusion 311.

[0049] In some embodiments, see Figures 6 to 9 A first connection hole 411 is provided on the first side wall 41, and a second connection hole 33 is correspondingly provided on the mounting bracket 3. The instrument panel frame body 1 is connected to the instrument panel reinforcement beam body 2 via a fastener 5. Specifically, the fastener 5 passes through the first connection hole 411 and the second connection hole 33 to secure the instrument panel frame body 1 to the instrument panel reinforcement beam body 2. This embodiment utilizes an installation method that combines a spring clip 31 for engagement and a fastener 5 for fixation. After the spring clip 31 and the instrument panel frame body 1 are assembled, engaged, positioned, and locked, the fastener 5 is then installed. Compared to conventional solutions that utilize only bolts or screws for fixation, the installation strength is significantly improved, and the mounting point is less likely to loosen or disengage under conditions of excessive vehicle vibration.

[0050] Although this embodiment also adopts the fastening method of fasteners 5, the strength of the installation position is enhanced by the installation cavity 4 of the instrument panel frame body 1, and the setting of the supporting flange 32 of the instrument panel reinforcement beam body 2, which improves the structural strength of the installation position and reduces the risk of deformation and warping, thereby avoiding the risk of concentrated stress accumulation after installation by the fasteners 5 and the risk of the fasteners 5 loosening and detaching due to vehicle vibration.

[0051] In particular, the assembly method of the clamping and fastener 5 is adopted. After the mounting bracket 3 is extended into the mounting cavity 4, the clamping of the elastic protrusion 311 and the clamping hole 412 can play a role of pre-tightening and positioning, and then the fastener 5 can be operated. Manual positioning is no longer required, and the assembly accuracy and convenience are greatly improved.

[0052] Optionally, the fastener 5 may be a bolt, a self-tapping screw or a snap fastener.

[0053] In some embodiments, see Figure 8 and Figure 9The second connecting hole 33 has a guide flange 34 bent away from the first side wall 41 around the periphery of the second connecting hole 33, and the guide flange 34 forms a guide conical surface for guiding the fastener 5. By providing the guide conical surface on the second connecting hole 33, the fastener 5 can be easily aligned with the second connecting hole 33 during assembly, greatly improving the convenience of installation.

[0054] In some embodiments, referring to Figure 8 The conical angle β formed by the guide conical surface is 45°-60°. If the conical angle β is too large, the gap after the fastener 5 is inserted into the second connecting hole 33 is too large, which is prone to looseness and poor fastening effect. If the conical angle β is too small, it is not easy to insert the fastener 5 into the second connecting hole 33. In this embodiment, the conical angle β is 45°-60°. The corner of the guide flange 34 is transitioned by a circular arc, which not only avoids the risk of stress concentration caused by sharp corners, but also facilitates the alignment of the fastener 5 with the guide conical surface, greatly improving the convenience of assembly. Specifically, the conical angle β is 60°, and the circular angle R of the circular arc transition is 3mm.

[0055] In some embodiments, the smallest aperture formed by the guide conical surface is smaller than the diameter of the fastener 5, so as to facilitate the interference fit between the fastener 5 and the second connecting hole 33.

[0056] In combination with Figure 8 It is understood that when the fastener 5 is a self-tapping screw, the diameter φa of the second connecting hole 33 is between the large diameter and the small diameter of the screw, so that the screw can be locked after being tightened. For example, a cross-slot large semi-circular head self-tapping screw (Q2734213F31E) is used, with the following specifications: screw small diameter 3.1mm, large diameter 4.22mm, pitch 1.4mm, thickness t of the mounting bracket 3=1.2mm, and ∮a=3.3mm.

[0057] When other specifications of screws are used, the diameter φa of the second connecting hole 33 can be calculated according to the thickness t of the mounting bracket 3 and the specifications of the screw, to ensure that the screw thread small diameter and the second connecting hole 33 have at least a 0.1mm gap.

[0058] In other feasible embodiments, the conical angle β, the circular angle R of the circular arc transition, the height h of the guide flange 34, and the thickness t of the mounting bracket 3 can be adjusted, and other specifications of self-tapping screws can be replaced. Alternatively, the second connecting hole 33 can be a common circular hole.

[0059] In some embodiments, a fastening nut (not shown in the figure) is arranged on the side of the mounting bracket 3 away from the first side wall 41, the fastening nut is concentric with the second connecting hole 33, and the fastener 5 is connected with the fastening nut. In this scheme, the fastening nut is welded on the mounting bracket 3, and the mounting and fixation of the instrument panel framework body 1 are realized by the screw connection between the bolt and the fastening nut.

[0060] In the above embodiments, the description of each embodiment has its own focus, and the parts not described or recorded in a certain embodiment can be referred to the relevant description of other embodiments.

[0061] Based on the same inventive concept, the embodiments of the present application also provide a vehicle comprising the mounting structure of the instrument panel framework assembly.

[0062] The vehicle provided by the embodiments of the present application can improve the convenience of assembling the instrument panel framework body 1 and the instrument panel reinforcing beam body 2, can improve the firmness of the instrument panel framework body 1 and the instrument panel reinforcing beam body 2 after mounting, and avoids the risk that the instrument panel framework body 1 and the instrument panel reinforcing beam body 2 cannot be aligned, resulting in difficult assembly and poor strength of the mounting point.

[0063] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
