[0043] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0044] Embodiment 1

[0045] This embodiment relates to a front panel metal structure, which is combined with Figures 1 to 3 As shown, the front wall sheet metal structure includes a front wall panel 1 and a front wall reinforcement plate 2 which is snap-fitted and connected to the front wall panel 1 .

[0046] A cavity 10 is formed between the dash reinforcing plate 2 and the dash panel 1, and a foamable filler 3 is disposed in the cavity 10. In addition, a hole 32 is disposed on the filler 3, and the hole 32 penetrates the filler 3, and the filler 3 is positioned in the cavity 10 by a clamping structure.

[0047] At this time, the utility model, through the cavity 10 formed by the front panel 1 and the front panel reinforcement plate 2, and the foamable filling member 3 arranged in the cavity 10, can not only utilize the high structural strength of the cavity 10 and the filling of the cavity 10 by the foamed filling member 3 to improve the overall rigidity of the front panel, but also form a three-layer sound insulation structure for the overall front panel, thereby improving the sound insulation performance of the front panel.

[0048] At the same time, by utilizing the design of the hole 32 on the filling piece 3 and positioning the filling piece 3 in the cavity 10 through a snap-fit ​​structure, the stability of the installation of the filling piece 3 in the cavity 10 and the sufficient foaming of the filling piece 3 can be ensured, thereby helping to improve the overall performance of the front enclosure.

[0049] Based on the above overall introduction, specifically, continue to refer to Figures 1 to 3 , and combined with Figure 7 and Fig. 9 As shown, as a preferred embodiment, in this embodiment, the front wall reinforcement plate 2 is located on the side of the front wall plate 1 facing the front cabin, and is connected to the upper part of the front wall plate 1 by buckling welding, and forms a cavity 10 between the front wall plate 1. The filler 3 can be foamed, and the filler 3 is positioned in the cavity 10 through a snap-fit ​​structure. In this embodiment, the filler 3 can be made of ethylene propylene rubber, for example.

[0050] In specific implementation, the cavity 10 is generally formed by stamping the front panel reinforcement plate 2, and snapping the front panel reinforcement plate 2 with the front panel 1 to form the rear structure. Therefore, preferably, the snap-fit ​​structure can be located between the filling piece 3 and the front panel reinforcement plate 2, which is beneficial to the arrangement of the filling piece 3.

[0051] At this time, the filler 3 is connected to the dash reinforcing plate 2 through a snap-fit ​​structure and is sandwiched between the dash reinforcing plate 2 and the dash reinforcing plate 2. After the dash reinforcing plate 2, the filler 3 and the dash 1 are assembled together, the filler 3 is foamed by high-temperature baking and coating to fill the cavity 10, and the filler 3, the dash 1 and the dash reinforcing plate 2 form a three-layer sound insulation structure, which can fully reduce the transmission of engine noise to the cab, and is conducive to improving the quietness of the cab.

[0052] In addition, it should be noted that the structure of the filler 3 can be specifically designed according to the shape of the cavity 10. In this embodiment, the width of the cavity 10 in the X direction of the vehicle body is approximately 9 mm on average, and the thickness of the filler 3 is approximately 3 mm. The hole 32 that penetrates the filler 3 is preferably located at a larger Z-direction portion of the filler 3, so as to ensure sufficient foaming of the filler 3.

[0053] As a preferred embodiment, in this embodiment, the snap-in structures are multiple and spaced apart, and from the front and rear direction of the vehicle, at least the left and right ends of the filler 3, and the top and bottom of the filler 3 are provided with snap-in structures. Figures 2 to 6 As shown, the left and right ends and the top and bottom of the filling piece 3 are provided with a clamping structure, so that the positioning effect of the filling piece can be ensured.

[0054] The specific structure of the clamping structure of this embodiment is as a preferred embodiment. Figures 2 to 6 , and combined with Fig. 9 and Fig.11 As shown, the clamping structure includes a clamping hole 23 provided on the front wall reinforcement plate 2, a clamping through hole 31 provided on the filling piece 3, and a clamping head 4. The clamping hole 23 corresponds to the clamping through hole 31, and the clamping head 4 passes through the clamping through hole 31 and is clamped at the clamping hole 23, thereby making the filling piece 3 clamped and connected to the front wall reinforcement plate 2. At this time, the clamping structure is provided using the clamping hole 23, the clamping through hole 31 and the clamping head 4, and its structure is simple, and it is easy to design, manufacture and assemble.

[0055] Based on the setting of the clamping structure, in this embodiment, see Figure 1 , Figures 3 to 5 , and combined with Figures 7 to 9 As shown, an exhaust channel 201 located at the top of the cavity 10 and a drain channel 202 located at the bottom of the cavity 10 are also provided between the front wall reinforcement plate 2 and the front wall 1. The provision of the exhaust channel 201 can avoid the electrophoresis air chamber problem existing during the electrophoresis of the front wall. The provision of the drain channel 202 can ensure the effective discharge of the electrophoresis liquid, which helps to ensure the electrophoresis effect.

[0056] As a preferred embodiment, the exhaust channels 201 of this embodiment are multiple and arranged at intervals, so that the exhaust effect can be ensured. Also as a preferred embodiment, the drain channels 202 are multiple and arranged at intervals, which can facilitate the rapid discharge of the electrophoresis liquid and ensure the electrophoresis effect.

[0057] See also Figures 3 to 5 ,as well as Figure 7 and Figure 8As shown, in this embodiment, as a preference, a plurality of exhaust bosses 21 bulging toward a side away from the front panel 1 are provided on the front panel reinforcement plate 2, and when the front panel reinforcement plate 2 is buckled with the front panel 1, the plurality of exhaust bosses 21 respectively form the plurality of exhaust channels 201 described above with the front panel 1. By forming the exhaust bosses 21 on the front panel reinforcement plate 2, the exhaust channels 201 are formed by the exhaust bosses 21 and the front panel 1, and the structure is simple, which is convenient for design and preparation.

[0058] See also Figures 3 to 5 ,as well as Fig. 9 and Fig.10 As shown, in this embodiment, as a preference, a plurality of drain bosses 22 bulging toward the side away from the front panel 1 are also provided on the front panel reinforcement plate 2. When the front panel reinforcement plate 2 is buckled with the front panel 1, the plurality of drain bosses 22 respectively form the plurality of drain channels 202 described above with the front panel 1. The drain bosses 22 formed on the front panel reinforcement plate 2 enable the drain channels 202 to be formed by the drain bosses 22 and the front panel 1, which also has the characteristics of simple structure and convenient design and preparation.

[0059] It should be noted that the structures of the exhaust boss 21 and the drain boss 22 are determined according to the volume of gas in the cavity 10 and the volume of electrophoretic liquid in the cavity 10 during electrophoresis. In this embodiment, the average spacing between the multiple exhaust bosses 21 is about 110 mm, and the average spacing between the multiple drain bosses 22 is about 100 mm. The average spacing specifically refers to the average value of the distance between the center lines of each adjacent two exhaust bosses 21 or each adjacent two drain bosses 22.

[0060] In this embodiment, look back Figure 4 As shown, a mounting point 5 for mounting components in the front cabin is also provided on the front dash reinforcement plate 2. The provision of the mounting point 5 can facilitate the installation and arrangement of the components in the front cabin, which is beneficial to improving the functionality of the front dash assembly. It should be noted here that the components in the front cabin can be, for example, heat insulation pads, air conditioning four-way valves and other components. In this case, the provision of the mounting point 5 can provide an installation basis for the above components, and the provision of the mounting point 5 on the front dash reinforcement plate 2 after the overall stiffness is improved is also beneficial to ensuring the stiffness of the mounting points 5 of each component.

[0061] Preferably, the mounting point 5 specifically includes a projection welding stud provided on the front wall reinforcement plate 2. Of course, it can be understood that the mounting point 5 can also only use a projection welding nut, or use a projection welding stud and a projection welding nut, which is selected accordingly according to actual needs. In this embodiment, the mounting point 5 uses a projection welding stud or a projection welding nut, which has the characteristics of simple structure and easy setting, and is also convenient for the installation and arrangement of the components in the front cabin.
