[0037] Please also read Figures 1 to 3 The dash panel assembly and the vehicle provided by the present invention are now described. The dash panel assembly includes a dash inner component 1 and a dash outer component 2. The dash inner component 1 is connected to the windshield cross beam assembly 5 and is located below the windshield cross beam assembly 5. The dash outer component 2 is arranged in front of the dash inner component 1 and is connected to the bottom of the ventilation cover 8. The dash outer component 2 and the dash inner component 1 form a buffer space 103 in the front-to-back direction.

[0038] Compared with the prior art, the dash panel assembly provided by the present invention forms a double-layer dash panel structure through the dash inner component 1 and the dash outer component 2, and forms a buffer space 103 in the front and rear directions. The double-layer structure is not only stronger, but also when the front of the vehicle is subjected to external force, the external force is first transmitted to the dash outer component 2, and the external force is released into the buffer space 103 by using the connection structure between the dash outer component 2 and the ventilation cover 8. The fully released external force is transmitted to the dash inner component 1, and the dash inner component 1 is transmitted to the windshield cross beam assembly 5, and then transmitted to the rear of the vehicle through the windshield cross beam assembly 5, which is beneficial to protecting the safety of the front row passengers in the cab. In addition, the buffer space 103 can also achieve the effect of sound insulation and heat insulation, reduce the noise inside the vehicle, and reduce the heat exchange between the inside and outside of the vehicle.

[0039] It should be noted that both the front enclosure inner component 1 and the front enclosure outer component 2 are made of thin metal plates, and the deformability of the thin plates is used to introduce the collision energy into the buffer space 103 for large-distance crushing and energy absorption, thereby efficiently releasing the collision energy.

[0040] Specifically, the bottom of the front inner assembly 1 and the front outer assembly 2 are connected, so as to close the bottom of the buffer space 103. The top of the buffer space 103 of the ventilation cover 8 is closed by the front windshield beam assembly 5 and the ventilation cover 8.

[0041] In some embodiments, see Figures 1 to 6 The front panel assembly also includes a reinforcing component 3 arranged in the buffer space 103, the top of the reinforcing component 3 is connected to the front windshield beam assembly 5, and the bottom is connected to the front panel inner component 1, and the reinforcing component 3 divides the buffer space 103 from front to rear into a front buffer cavity 1031 and a rear buffer cavity 1032.

[0042] The reinforcement component 3 further divides the buffer space 103 from front to back into a front buffer cavity 1031 and a rear buffer cavity 1032. Since the reinforcement component 3 is connected to the front windshield beam and the front inner component 1 respectively, the strength of the front panel assembly is further strengthened. In addition, after the front of the vehicle is subjected to external force, the front outer component 2 first bears the external force, and then releases it to the front buffer cavity 1031, guiding the external force to fully collapse and release during the transmission process, and then transmits it to the reinforcement component 3. On the one hand, the reinforcement component 3 transmits the external force to the front windshield beam assembly 5 and the front inner component 1, and on the other hand, the external force is released into the rear buffer cavity 1032, further weakening the damage caused by the external force to the components inside the cab. In this embodiment, the front outer component 2, the reinforcement component 3 and the front inner component 1 form a load-bearing structure, so that the external force is gradually weakened during the transmission process, and the strength and anti-deformation ability are increased by connecting with the front windshield beam assembly 5 respectively.

[0043] In some embodiments, see Figure 1 and Figure 6 The reinforcement component 3 includes a left longitudinal reinforcement beam 301 and a right longitudinal reinforcement beam 302 of the front enclosure, which are spaced from left to right. The tops of the left longitudinal reinforcement beam 301 and the right longitudinal reinforcement beam 302 of the front enclosure are connected to the front windshield crossbeam assembly 5, and the bottoms are connected to the front enclosure inner component 1. The rear buffer cavity 1032 includes a left buffer chamber formed by the left longitudinal reinforcement beam 301 and the front enclosure inner component 1, and a rear buffer chamber formed by the right longitudinal reinforcement beam 302 and the front enclosure inner component 1.

[0044] The tops of the left longitudinal reinforcement beam 301 and the right longitudinal reinforcement beam 302 of the front enclosure are respectively connected to the front windshield cross beam assembly 5, and the bottoms are respectively connected to the front enclosure inner component 1, and the main load-bearing structure of the vehicle body is connected in the up-down direction to form a frame-type front enclosure reinforcement structure. The left longitudinal reinforcement beam 301 and the right longitudinal reinforcement beam 302 of the front enclosure correspond to the positions of the main driver and the co-driver in the cab, respectively, which is conducive to protecting the safety of the legs of passengers in the cab. In addition, the left longitudinal reinforcement beam 301 and the right longitudinal reinforcement beam 302 of the front enclosure are arranged at intervals in the left-right direction. After the external force is transmitted to the left longitudinal reinforcement beam 301 and the right longitudinal reinforcement beam 302 of the front enclosure, space is reserved in the left-right direction to avoid the left longitudinal reinforcement beam 301 or the right longitudinal reinforcement beam 302 of the front enclosure from affecting each other after deformation. In addition, after the left longitudinal reinforcement beam 301 and the right longitudinal reinforcement beam 302 of the front enclosure are subjected to force, they are respectively transmitted to the rear of the vehicle through the front windshield cross beam assembly 5 and the front enclosure inner component 1, so as to avoid local stress concentration and damage to the front enclosure.

[0045] Specifically, the bottoms of the front dash left longitudinal reinforcement beam 301 and the front dash right longitudinal reinforcement beam 302 are respectively connected to the front dash inner reinforcement beam 102 .

[0046] In some embodiments, see Figure 1 and Figure 3 The front panel assembly also includes a partition plate 4 connected to the front panel inner component 1 and the front panel outer component 2 respectively, and the partition plate 4 divides the buffer space 103 from top to bottom into an upper bearing cavity 1033 and a lower bearing cavity 1034.

[0047] The upper load-bearing cavity 1033 and the lower load-bearing cavity 1034 are superimposed in the up and down directions to form a high-strength load-bearing area. The external force is released through the upper load-bearing cavity 1033 and the lower load-bearing cavity 1034 respectively. The load-bearing cavity formed by the partition plate 4, the front enclosure outer component 2 and the front enclosure inner component 1 provides support for the lower part of the front enclosure, thereby reducing the probability of deformation of the lower part of the front enclosure due to force.

[0048] It should be noted that when the partition plate 4 and the reinforcement component 3 are present in one embodiment at the same time, the reinforcement component 3 divides the buffer space 103 into a front buffer cavity 1031 and a rear buffer cavity 1032, and the partition plate 4 is disposed in the front buffer cavity 1031, and divides the front buffer cavity 1031 into an upper bearing cavity 1033 and a lower bearing cavity 1034. Thus, the buffer space 103 is formed with multiple bearing areas in the front and rear reverse directions and in the up and down directions, thereby increasing the path and speed of the external force spreading outward.

[0049] In some embodiments, see Figures 1 to 3 The front inner assembly 1 includes a front inner panel 101 and a front inner reinforcement beam 102 connected in sequence from top to bottom. The front inner panel 101 is connected to the bottom of the front windshield cross beam, and the front inner reinforcement beam 102 is connected to the front outer assembly 2.

[0050] The front enclosure inner panel 101 is connected with the front enclosure inner reinforcement beam 102 to form the front enclosure inner component 1. The front enclosure inner component 1 is arranged as a split structure, which is not only convenient for processing and storage, but also more flexible in connection.

[0051] Optionally, the dash inner panel 101 and the dash inner reinforcement beam 102 are welded or screwed.

[0052] In some embodiments, see Figures 1 to 5 The front enclosure outer component 2 includes a front enclosure outer panel 201, a front enclosure receiving mechanism, a front enclosure outer connecting plate 203 and a front enclosure outer reinforcing beam 204 which are sequentially connected from top to bottom. The front enclosure outer panel 201 is connected to the ventilation cover plate 8, and the front enclosure outer reinforcing beam 204 is connected to the front enclosure inner component 1.

[0053] The front wall outer assembly 2 is divided into a front wall outer plate 201, a front wall receiving mechanism, a front wall outer connecting plate 203 and a front wall outer reinforcing beam 204, which is convenient for processing and production. During installation, the front wall outer plate 201 can be connected to the ventilation cover plate 8, the front wall outer reinforcing beam 204 can be connected to the front wall inner assembly 1, and then the front wall receiving mechanism and the front wall outer connecting plate 203 can be connected respectively. Alternatively, the front wall outer plate 201, the front wall receiving mechanism, the front wall outer connecting plate 203 and the front wall outer reinforcing beam 204 can be connected in sequence, and then connected to the ventilation cover plate 8 and the front wall inner assembly 1 respectively, so that the installation sequence is more flexible.

[0054] Optionally, the width of the front outer reinforcement beam 204 in the left-right direction gradually increases from the middle to both ends, forming a necked structure. The above structure transitions a large cross section to a small cross section, realizes structural design based on the strength of the load-bearing requirements, meets high structural load-bearing requirements while reducing structural weight.

[0055] Specifically, the front wall outer panel 201, the front wall receiving mechanism, the front wall outer connecting plate 203 and the front wall outer reinforcing beam 204 are respectively arranged at an angle.

[0056] Optionally, the front wall outer panel 201, the front wall receiving mechanism, the front wall outer connecting plate 203 and the front wall outer reinforcing beam 204 are connected by screwing or welding respectively.

[0057] As a specific implementation of the front outer panel 201, please refer to Figure 4 and Figure 5 The front outer panel 201 includes a load-bearing plate body 2011 connected to the ventilation cover plate 8, and a cabin upper cross beam 2012 arranged at the bottom of the load-bearing plate body 2011. The cabin upper cross beam 2012 is a tubular member, and the front enclosure receiving structure is connected to the cabin upper cross beam 2012.

[0058] The upper cross beam of the airport is set as a tubular structure, which is stronger than the plate structure. When the front of the vehicle is subjected to external force, the front outer assembly 2 is subjected to force, and the force is dissipated to the cabin upper cross beam 2012 during the transmission process. Since the cabin upper cross beam 2012 is connected to the front enclosure receiving mechanism, it is easy to break or fail. Therefore, increasing the strength of this part is conducive to ensuring the stability of the connection and the strength of the entire front outer assembly 2.

[0059] Optionally, the cabin upper cross beam 2012 is screwed or welded to the front enclosure supporting mechanism.

[0060] Optionally, the cross-section of the cabin upper beam 2012 is polygonal, and the front enclosure receiving mechanism includes a plurality of connecting portions arranged at an angle, each connecting portion being attached to an outer side surface of one side of the cabin upper beam 2012, thereby increasing the contact area with the cabin upper beam 2012 and improving the connection stability.

[0061] In some embodiments, see Figure 4 The front enclosure receiving mechanism includes a front enclosure left plate 2021 and a front enclosure right plate 2022 distributed from left to right, and the front enclosure left plate 2021 is fixedly connected to the front enclosure right plate 2022.

[0062] The front wall receiving mechanism is split into the front wall left plate 2021 and the front wall right plate 2022, which is convenient for processing. In addition, the volume of each component is reduced, which is conducive to storage and storage.

[0063] Optionally, the left front panel 2021 and the right front panel 2022 are screwed or welded.

[0064] Based on the same inventive concept, the present invention also provides a vehicle. Figure 1 The vehicle includes the above-mentioned front panel assembly and a front windshield crossbeam assembly 5 connected to the top of the front inner component 1.

[0065] The vehicle provided by the present invention adopts the above-mentioned front panel assembly, and forms a double-layer front panel structure through the front panel inner component 1 and the front panel outer component 2, and forms a buffer space 103 in the front and rear directions. The double-layer structure is not only stronger, but also when the front of the vehicle is subjected to external force, the external force is first transmitted to the front panel outer component 2, and the external force is released into the buffer space 103 by using the connection structure between the front panel outer component 2 and the ventilation cover plate 8. The fully released external force is transmitted to the front panel inner component 1, and the front panel inner component 1 is transmitted to the front windshield beam assembly 5, and then transmitted to the rear of the vehicle through the front windshield beam assembly 5, which is conducive to protecting the safety of the front row passengers in the cab. In addition, the buffer space 103 can also achieve the effect of sound insulation and heat insulation, reduce the noise inside the vehicle, and reduce the heat exchange between the inside and outside of the vehicle.

[0066] In some embodiments, see Figures 1 to 3The windshield crossbeam assembly 5 includes a windshield upper crossbeam 501 and a windshield lower crossbeam 502 connected to the bottom of the windshield upper crossbeam 501 . The windshield lower crossbeam 502 and the windshield upper crossbeam 501 are enclosed in the up and down directions to form a crossbeam buffer cavity 503 . The front enclosure inner component 1 is connected to the windshield lower crossbeam 502 .

[0067] The upper crossbeam 501 of the front windshield and the lower crossbeam 502 of the front windshield form a crossbeam buffer cavity 503, and the crossbeam buffer cavity 503 is located above the buffer space 103, and overlaps with the buffer space 103 to form a high-strength load-bearing area in the upper and lower directions, so that after the external force is transmitted to the lower crossbeam 502 of the front windshield, it collapses and releases in the crossbeam buffer cavity 503, and then is transmitted to the upper crossbeam 501 of the front windshield, thereby preventing the front windshield glass from being damaged by the force.

[0068] In some embodiments, see Figure 1 The vehicle further includes a ventilation cover plate 8 connected to the lower cross beam 502 of the front windshield, and a middle channel connecting plate 7 connected to the front inner component 1.

[0069] The lower cross beam 502 of the front windshield and the ventilation cover 8 together close the top of the buffer space 103, and transmit the force of the front enclosure outer component 2 and the front enclosure inner component 1 to the rear of the vehicle, which is conducive to achieving the force dispersion effect. The middle channel connecting plate 7 is connected to the front enclosure inner component 1, and transmits the force of the front enclosure inner component 1 to the front floor of the vehicle, realizing the process of force transmission from the lower part of the vehicle body to the rear, which is conducive to achieving the force dispersion effect.

[0070] Optionally, the vehicle further includes a front enclosure connection assembly 6 connected to the front enclosure inner reinforcement beam 102. The front enclosure connection assembly 6 includes a front enclosure lower left connection plate 601 and a front enclosure lower right connection plate 602, and the middle channel connection plate 7 is respectively connected to the front enclosure lower left connection plate 601 and the front enclosure lower right connection plate 602 along the left and right directions. External force can be transmitted to the rear of the vehicle through the front enclosure connection assembly 6.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
