Description

Technical Field

[0001] This application belongs to the field of vehicle interior technology, and more specifically, relates to a display screen mounting structure, an instrument panel assembly, and a vehicle. Background Technology

[0002] As the automotive industry continues to advance, users are demanding higher levels of functionality and intelligence from vehicle interiors. This is most directly reflected in the continuous upgrades in the functionality and size of the displays mounted on the dashboard. However, as these displays become more feature-rich and larger, their weight also increases. Therefore, the traditional method of directly embedding the display in the dashboard is no longer adequate for the current requirements of stable installation. Utility Model Content

[0003] The purpose of this application is to provide a display screen mounting structure that improves the accuracy and stability of the display screen's mounting position on the dashboard, thereby enhancing the interior's quality and avoiding driving noise problems.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: This application provides a display screen mounting structure, including: The tube beam support is fixedly connected to the instrument panel reinforcing tube beam at one end, and extends backward and bends continuously at the other end to form the first connecting part and the second connecting part; The instrument panel frame has a first mounting part and a second mounting part, the first mounting part abutting against the first connecting part front to back, and the second mounting part abutting against the second connecting part vertically. The display screen body has a connecting rib that overlaps the second connecting part or the second mounting part; The first connecting part and the first mounting part are both fitted with at least one X-direction fastener, and the second connecting part, the second mounting part and the connecting rib are all fitted with at least one Z-direction fastener.

[0005] The beneficial effect of the solution shown in the embodiments of this application is that, compared with the prior art, by fixing the tube beam bracket on the instrument panel reinforcing tube beam and forming the first connecting part and the second connecting part by continuously bending the tube beam bracket, the first mounting part and the first connecting part of the instrument panel frame can be abutted in the front-rear direction of the vehicle body. Then, the X-direction fastener passes through the first connecting part and the first mounting part for fastening connection. This can provide fastening constraint on the instrument panel frame in the front-rear direction of the vehicle body, and enable the tube beam bracket to support the instrument panel frame, thereby compensating for the strength loss of the instrument panel frame caused by the opening of the display screen body and avoiding the instrument panel frame from collapsing and deforming under stress.

[0006] The second connecting part, the second mounting part of the instrument panel frame, and the connecting rib of the display screen body are stacked in the height direction of the vehicle body and fixed together by Z-direction fasteners. This not only limits the relative positional relationship between the display screen body and the instrument panel frame and improves the relative positional accuracy between the display screen body and the instrument panel frame, thereby ensuring assembly gap and surface difference, which is conducive to improving the interior texture, but also allows the display screen body to directly transmit force to the instrument panel reinforcing tube beam through the tube beam bracket based on the Z-direction fasteners, thereby ensuring the connection strength of the display screen body.

[0007] The second mounting part and the connecting rib are fixed to the second connecting part by Z-direction fasteners. This establishes a mutual cooperation relationship between the display body and the instrument panel frame, thereby avoiding the occurrence of mutual misalignment and friction noise between the display body and the instrument panel frame during driving on bumpy roads. Therefore, it helps to improve the vehicle's NVH (Noise, Vibration, Harshness) performance and driving experience.

[0008] In conjunction with the first aspect, in one possible implementation, the first mounting part is provided with a positioning rib, and the first connecting part is provided with a plurality of positioning holes of different positions and shapes; wherein, the positioning rib is inserted into the positioning hole that matches its position and shape.

[0009] In the above technical solution, the positioning ribs and corresponding positioning holes are inserted and engaged along the front-rear direction of the vehicle body to form Y-axis and Z-axis positioning of the instrument panel frame. Based on this, the X-axis fasteners provide X-axis fastening force to the first mounting part, which improves the assembly position accuracy of the instrument panel frame, helps to improve the uniformity of assembly gaps and eliminate assembly surface differences, further enhancing the interior quality. Furthermore, the multiple positioning holes with different positions and shapes on the first connecting part can adapt to different positioning rib structures on the instrument panel frame, thereby improving the adaptability of the tube beam bracket.

[0010] In some embodiments, the portion of the tube beam support located between the first connecting portion and the instrument panel reinforcing tube beam forms a third connecting portion. The first connecting portion bends upward at the rear end of the third connecting portion, and the second connecting portion bends backward at the upper end of the first connecting portion. The first mounting portion abuts forward against the rear side of the first connecting portion, and the second mounting portion abuts downward against the upper surface of the second connecting portion. The connecting rib overlaps with the second mounting portion.

[0011] In the above technical solution, the tube beam support forms a Z-shaped structure based on the first connecting part, the second connecting part and the third connecting part. This allows for the simultaneous acquisition of the first connecting part as the X-direction contact surface and the second connecting part as the Z-direction contact surface through a simple structural design. This avoids the adverse effects of complex structures on the overall vehicle weight and is beneficial to the vehicle's lightweight performance.

[0012] Since the dashboard frame is usually subjected to the pressing force of the driver and passengers, the first mounting part is abutted against the rear side of the first connecting part. This allows the first connecting part to support the first mounting part, thereby preventing the dashboard frame from collapsing or deforming under stress. The second connecting part provides support on the lower side of the second mounting part, further enhancing the load-bearing capacity of the dashboard frame and reducing the risk of collapse and deformation. At the same time, the connecting rib is attached above the second mounting part, which allows the display screen body to be disassembled and assembled without moving the dashboard frame and the tube beam bracket. This improves the convenience of disassembly, assembly, and maintenance of the display screen body.

[0013] For example, the bending area between the first connecting portion and the third connecting portion is provided with a first reinforcing rib, and the bending area between the first connecting portion and the second connecting portion is provided with a second reinforcing rib.

[0014] In the above technical solution, considering the deformation problem of bending angle change in the bending area when subjected to force, the two bending areas of the tube beam support are respectively provided with a first reinforcing rib and a second reinforcing rib. This can improve the overall structural rigidity of the tube beam support, avoid deformation of the tube beam support due to the force transmitted by the display screen body and the instrument panel frame, and thus improve the connection stability of the display screen body and the instrument panel frame.

[0015] For example, the third connecting part is provided with a third reinforcing rib that protrudes upward or is recessed downward, and the third reinforcing rib is provided with several weight-reducing holes.

[0016] In the above technical solution, since there is a certain distance between the instrument panel reinforcing tube beam and the instrument panel frame, the length of the third connection part is relatively large. Therefore, a raised or recessed third reinforcing rib is provided on the third connection part, which can improve the structural rigidity of the third connection part without increasing the weight of the tube beam support. This ensures the supporting rigidity of the tube beam support for the instrument panel frame and the display screen body, and is conducive to further improving the connection stability of the instrument panel frame and the display screen body. On this basis, by opening several weight-reducing holes on the first reinforcing rib, the overall weight of the tube beam support can also be reduced, thereby promoting the lightweighting of the entire vehicle.

[0017] In some possible implementations, at least one side of the tube beam support has a reinforcing flange that extends continuously along the edges of the third connection, the first connection, and the second connection.

[0018] In the above technical solution, by setting a reinforcing fold, the tube beam support can form an L-shaped or U-shaped cross-sectional structure, thereby improving the overall structural rigidity of the tube beam support. At the same time, the reinforcing fold extends continuously from the edge of the third connection part through the edge of the first connection part to the second connection part, thereby improving the structural rigidity of the two bending parts of the tube beam support and preventing the tube beam support from deforming under stress, which would affect the connection stability of the display screen body and the instrument panel frame.

[0019] For example, the width of the reinforced fold gradually narrows from the third connecting part to the second connecting part.

[0020] In the above technical solution, since the length of the third connecting part is relatively large, and the third connecting part needs to bear the force transmitted from the first connecting part and the second connecting part, while the first connecting part bears the force transmitted from the second connecting part, the third connecting part has the highest strength, the first connecting part is second, and the second connecting part is the lowest. Therefore, the reinforcing fold is set to gradually narrow based on the structural strength requirements at the corresponding position. This can promote weight reduction while ensuring that the overall structural strength of the tube beam support meets the requirements, which is conducive to achieving the vehicle's strength index.

[0021] In some embodiments, the reinforced folded edge is provided with at least one wire harness connection hole.

[0022] In the above technical solution, considering the wiring harness arrangement requirements on the display screen body, wiring harness connection holes are set on the reinforced folded edge. This not only facilitates the fixing of the wiring harness and prevents the wiring harness connected to the display screen body from shaking and colliding with the tube beam bracket during driving due to lack of restraint, thus avoiding abnormal noise, but also helps to reduce the weight of the tube beam bracket, thereby contributing to the overall vehicle lightweighting index.

[0023] Secondly, embodiments of this application also provide an instrument panel assembly, including the aforementioned display screen mounting structure.

[0024] The beneficial effect of the instrument panel assembly provided in this application embodiment is that, compared with the prior art, the above-mentioned display screen mounting structure can abut the first mounting part and the first connecting part of the instrument panel frame in the front-rear direction of the vehicle body, and then fasten them by passing through the first connecting part and the first mounting part with X-direction fasteners. This can provide fastening constraints on the instrument panel frame in the front-rear direction of the vehicle body, and enable the tube beam bracket to support the instrument panel frame, thereby compensating for the strength loss of the instrument panel frame caused by the opening of the display screen body, and avoiding the instrument panel frame from collapsing and deforming under stress.

[0025] The second connecting part, the second mounting part of the instrument panel frame, and the connecting rib of the display screen body are stacked in the height direction of the vehicle body and fixed together by Z-direction fasteners. This not only limits the relative positional relationship between the display screen body and the instrument panel frame and improves the relative positional accuracy between the display screen body and the instrument panel frame, thereby ensuring assembly gap and surface difference, which is conducive to improving the interior texture, but also allows the display screen body to directly transmit force to the instrument panel reinforcing tube beam through the tube beam bracket based on the Z-direction fasteners, thereby ensuring the connection strength of the display screen body.

[0026] The second mounting part and the connecting rib are fixed to the second connecting part by Z-direction fasteners, thereby establishing a mutual cooperation relationship between the display body and the instrument panel frame. This can prevent the display body and the instrument panel frame from misaligning and causing friction noise during driving on bumpy roads, thus helping to improve the vehicle's NVH performance and driving experience.

[0027] Thirdly, embodiments of this application also provide a vehicle including an instrument panel assembly employing the aforementioned display screen mounting structure.

[0028] The beneficial effects of the vehicle provided in this application embodiment are that, compared with the prior art, by providing a first connecting part and a second connecting part through the tube beam bracket, the first mounting part on the instrument panel frame can be fixed to the first connecting part. The connecting rib of the display screen body and the second mounting part on the instrument panel frame are connected together to the second connecting part. This not only allows the display screen body to directly transmit force to the instrument panel reinforcing tube beam through the tube beam bracket, thereby avoiding the instrument panel frame bearing the force of the display screen body, which is beneficial to improving the installation stability of the instrument panel frame and the display screen body respectively, but also establishes a common connection relationship between the display screen body and the instrument panel frame, thereby improving the relative positional accuracy between the display screen body and the instrument panel frame, thereby improving the uniformity of the assembly gap and eliminating surface differences, which is beneficial to improving the interior refinement and reducing driving noise problems, thereby improving the vehicle's NVH performance and driving experience.

In the description of this application, "several" means two or more, unless otherwise explicitly specified.

[0035] It should be noted that the directions or positional relationships indicated by "front", "rear", "inner", "outer", "up", and "down" in this embodiment are based on the vehicle's own orientation. The front of the vehicle represents "front", the rear of the vehicle represents "rear", the top of the vehicle represents "up", the bottom of the vehicle represents "down", the "inner" side refers to the side facing the driver's cab, and the "outer" side refers to the side facing the driver's cab.

[0038] In existing technology, the dashboard reinforcing beam serves as the carrier for the dashboard assembly of interior trim components and also houses various electrical components, air conditioning, etc. It typically exists as a tubular structure and is therefore often referred to as a tubular beam. The dashboard body structurally includes a panel that serves as the interior trim surface and a frame structure fixedly connected to or integrally formed on the back of the panel. To meet the reliable installation requirements of the display screen, a bracket is typically welded to the dashboard reinforcing tube beam. The connecting ribs on the back of the display screen are overlapped and fixed to the bracket for Z-axis fixation. This allows the display screen to directly transmit force to the dashboard reinforcing tube beam through the bracket, thereby avoiding excessive stress on the dashboard body frame. However, due to the lack of fit between the display screen and the dashboard body, the gap and surface difference between them cannot be guaranteed, affecting the interior texture and easily generating friction noise during driving on bumpy roads, thus affecting the driving experience. This is also the key problem addressed by the embodiments of this application.

[0039] Please refer to the following: Figures 1 to 4 The display screen mounting structure provided in this application is now described. The display screen mounting structure includes a tube beam support 10, an instrument panel frame 30, and a display screen body 40; one end of the tube beam support 10 is fixedly connected to the instrument panel reinforcing tube beam 20, and the other end extends rearward and is continuously bent to form a first connecting part 11 and a second connecting part 12; the instrument panel frame 30 has a first mounting part 31 and a second mounting part 32, the first mounting part 31 abuts against the first connecting part 11 front to back, and the second mounting part 32 abuts against the second connecting part 12 vertically; the display screen body 40 has a connecting rib 41 that overlaps the second connecting part 12 or the second mounting part 32; wherein, the first connecting part 11 and the first mounting part 31 are both provided with at least one X-direction fastener 50, and the second connecting part 12, the second mounting part 32, and the connecting rib 41 are all provided with at least one Z-direction fastener 60.

[0040] It should be noted that in this embodiment, both the X-direction fastener 50 and the Z-direction fastener 60 can be threaded fasteners. The X-direction fastener 50 can be understood as passing through the first mounting part 31 and the first connecting part 11 along the X direction and being fastened. The Z-direction fastener 60 can be understood as passing through the connecting rib 41, the second mounting part 32 and the second connecting part 12 along the Z direction and being fastened.

[0041] It should be explained that in this embodiment, the tube beam support 10 refers to the support that is fixed to the instrument panel reinforcing tube beam 20, and is not limited to a tube beam structure. Of course, the tube beam support 10 can be a tubular structure or a slat structure, and is not specifically limited here.

[0042] It should be understood that in this embodiment, the instrument panel reinforcing tube beam 20 can be arranged with multiple tube beam supports 10 at intervals along the width direction of the vehicle body. Each tube beam support 10 is connected to different parts of the instrument panel frame 30 and the display screen body 40. In this embodiment, only the connection structure between one tube beam support 10 and the instrument panel frame 30 and the display screen body 40 is used as an example for explanation.

[0043] Compared with the prior art, the display screen mounting structure provided in this application, by fixing the tube beam bracket 10 on the instrument panel reinforcing tube beam 20 and forming the first connecting part 11 and the second connecting part 12 by continuously bending the tube beam bracket 10, can abut the first mounting part 31 of the instrument panel frame 30 and the first connecting part 11 in the front-rear direction of the vehicle body. Then, the X-direction fastener 50 passes through the first connecting part 11 and the first mounting part 31 for fastening connection. This can provide fastening constraint on the instrument panel frame 30 in the front-rear direction of the vehicle body, and enable the tube beam bracket 10 to support the instrument panel frame 30, thereby compensating for the strength loss of the instrument panel frame 30 caused by the opening of the display screen body 40 and preventing the instrument panel frame 30 from collapsing and deforming under stress.

[0044] The second connecting part 12, the second mounting part 32 of the instrument panel frame 30, and the connecting rib 41 of the display body 40 are stacked in the height direction of the vehicle body and fixed together by the Z-direction fastener 60. This not only limits the relative positional relationship between the display body 40 and the instrument panel frame 30 and improves the relative positional accuracy between the display body 40 and the instrument panel frame 30, thereby ensuring the assembly gap and surface difference, which is conducive to improving the interior texture, but also allows the display body 40 to directly transmit force to the instrument panel reinforcing tube beam 20 through the tube beam bracket 10 based on the Z-direction fastener 60, thereby ensuring the connection strength of the display body 40.

[0045] The second mounting part 32 and the connecting rib 41 are fixed together to the second connecting part 12 by the Z-direction fastener 60, thereby establishing a mutual cooperation relationship between the display body 40 and the instrument panel frame 30. This can prevent the display body 40 and the instrument panel frame 30 from misaligning and causing friction noise during driving on bumpy roads, thus helping to improve the vehicle's NVH performance and driving experience.

[0046] It should be noted that, please refer to... Figure 3 and Figure 4 Understood, considering ease of assembly, in this embodiment, the first mounting part 31 is provided with a first mounting hole suitable for the X-direction fastener 50 to pass through, the second mounting part 32 and the connecting rib 41 are provided with a second mounting hole suitable for the Z-direction fastener 60 to pass through, the first connecting part 11 is provided with a first threaded hole or a first projection weld nut 114 is welded to it for screwing with the X-direction fastener 50, and the second connecting part 12 is provided with a second threaded hole or a second projection weld nut 121 is welded to it for screwing with the Z-direction fastener 60.

[0047] In some embodiments, see Figure 2 and Figure 4 The first mounting part 31 is provided with a positioning rib 311, and the first connecting part 11 is provided with a plurality of positioning holes 111 with different positions and shapes; wherein, the positioning rib 311 is inserted into the positioning hole 111 that matches its position and shape.

[0048] After the Z-direction fastener 60 passes through the first mounting part 31 and the first connecting part 11, it can provide Y-direction and Z-direction positioning for the instrument panel frame 30 to a certain extent. However, considering the assembly gap of the Z-direction fastener 60, it is difficult to guarantee high precision requirements by simply relying on it for positioning. Therefore, in this embodiment, the X-direction insertion and mating structure of the positioning rib 311 and the positioning hole 111 is provided to provide Y-direction and Z-direction positioning for the instrument panel frame 30, thereby ensuring the assembly position accuracy of the instrument panel frame 30.

[0049] The X-direction fastening force provided by the X-direction fastener 50 to the first mounting part 31 ensures that the first mounting part 31 is tightly abutted against the first connecting part 11, thereby achieving X-direction positioning of the instrument panel frame 30. Combined with the aforementioned plug-in positioning structure, this allows the instrument panel frame 30 to achieve reliable positioning in the X, Y, and Z directions. This not only improves the uniformity of assembly gaps and eliminates assembly surface differences but also enhances the connection stability of the instrument panel frame 30. Furthermore, the multiple positioning holes 111 with different positions and shapes on the first connecting part 11 can accommodate different positioning rib 311 structures on the instrument panel frame 30, thereby improving the adaptability of the tube beam support 10.

[0050] Specifically, the first connecting part 11 has mutually spaced round holes and elliptical holes as positioning holes 111. Square holes, triangular holes, etc. can also be provided as positioning holes 111, but no specific limitation is made here.

[0051] As one specific structural form of the aforementioned tube beam support 10, please refer to Figures 2 to 4 The tube beam bracket 10 forms a third connection 13 at the position between the first connection 11 and the instrument panel reinforcing tube beam 20. The first connection 11 is bent upward at the rear end of the third connection 13, and the second connection 12 is bent backward at the upper end of the first connection 11. The first mounting part 31 abuts forward against the rear side of the first connection 11, the second mounting part 32 abuts downward against the upper surface of the second connection 12, and the connecting rib 41 overlaps the second mounting part 32.

[0052] The tube beam support 10 can be a one-piece stamped part or a welded part. Considering the structural strength and lightweight index, it is preferred to adopt a one-piece molded part. Structurally, it forms a Z-shaped structure based on the first connecting part 11, the second connecting part 12 and the third connecting part 13. Thus, the first connecting part 11, which serves as the X-direction contact surface, and the second connecting part 12, which serves as the Z-direction contact surface, can be obtained simultaneously through simple structural design. This can avoid the adverse effects of complex structures on the overall vehicle weight and is beneficial to the overall vehicle lightweight index.

[0053] Since the instrument panel frame 30 is usually subjected to the pressing force of the driver and passengers, the first mounting part 31 is abutted against the rear side of the first connecting part 11. This allows the first connecting part 11 to support the first mounting part 31, thereby preventing the instrument panel frame 30 from collapsing and deforming under stress. The second connecting part 12 provides support on the lower side of the second mounting part 32, further improving the load-bearing capacity of the instrument panel frame 30 and reducing the risk of collapse and deformation. At the same time, the connecting rib 41 is attached above the second mounting part 32, thereby enabling the display screen body 40 to be disassembled and assembled without moving the instrument panel frame 30 and the tube beam bracket 10. This improves the convenience of disassembly, assembly and maintenance of the display screen body 40.

[0054] It should be noted that, as Figure 2 As shown, in this embodiment, the bending area between the first connecting part 11 and the third connecting part 13 is provided with a first reinforcing rib 112, and the bending area between the first connecting part 11 and the second connecting part 12 is provided with a second reinforcing rib 113.

[0055] Considering the deformation problem caused by changes in bending angle when the bending area is subjected to force, the two bending areas of the tube beam support 10 are respectively provided with a first reinforcing rib 112 and a second reinforcing rib 113. This can improve the overall structural rigidity of the tube beam support 10, prevent the tube beam support 10 from deforming due to the force transmitted by the display body 40 and the instrument panel frame 30, and thus improve the connection stability of the display body 40 and the instrument panel frame 30.

[0056] The first reinforcing rib 112 and the second reinforcing rib 113 mentioned above can be additionally welded to the bending area, or they can be protruding or recessed ribs integrally formed in the bending area. Considering weight reduction, the integrally formed rib structure is preferred.

[0057] like Figure 2 As shown, in some embodiments, the third connecting portion 13 is provided with a third reinforcing rib 131 that protrudes upward or is recessed downward, and the third reinforcing rib 131 is provided with a plurality of weight-reducing holes 132.

[0058] Because there is a certain distance between the instrument panel reinforcing tube beam 20 and the instrument panel frame 30, the length of the third connecting part 13 is relatively large. Therefore, a raised or recessed third reinforcing rib 131 is provided on the third connecting part 13. This can improve the structural rigidity of the third connecting part 13 without increasing the weight of the tube beam support 10, thereby ensuring the support rigidity of the tube beam support 10 for the instrument panel frame 30 and the display screen body 40, which is conducive to further improving the connection stability of the instrument panel frame 30 and the display screen body 40. On this basis, by opening several weight reduction holes 132 on the third reinforcing rib 131, the overall weight of the tube beam support 10 can also be reduced, thereby promoting the lightweighting of the entire vehicle.

[0059] For some possible implementations, please refer to [link / reference]. Figure 2 and Figure 3 The tube beam support 10 has a reinforcing flange 14 on at least one side, which extends continuously along the edges of the third connecting portion 13, the first connecting portion 11, and the second connecting portion 12.

[0060] An L-shaped cross-section structure can be formed by setting a reinforcing fold 14 on one side of the pipe beam support 10, and a U-shaped cross-section structure can be formed by setting reinforcing fold 14 on both sides of the pipe beam support 10. Both methods can improve the overall structural rigidity of the pipe beam support 10. The U-shaped cross-section structure is preferred here.

[0061] The reinforced folded edge 14 extends continuously from the edge of the third connecting part 13 through the edge of the first connecting part 11 to the second connecting part 12, thereby improving the structural rigidity of the two bending parts of the tube beam support 10 and preventing the tube beam support 10 from deforming under stress, which would affect the connection stability of the display screen body 40 and the instrument panel frame 30.

[0062] Considering the requirements of the forming process, since the reinforcing fold 14 is located on the inner corner side of the bending area of ​​the first connecting part 11 and the second connecting part 12, the reinforcing fold 14 is prone to crushing deformation at this position during bending forming. Therefore, a process groove 142 can be opened in the bending area of ​​the reinforcing fold 14 to ensure the flatness of the reinforcing fold 14 at this position after forming, thereby ensuring the strength enhancement effect of the reinforcing fold 14 on the bending part.

[0063] In addition, the tube beam bracket 10 can be fixed to the instrument panel reinforcing tube beam 20 by welding. The reinforcing fold 14 can also increase the connection contact area between the end of the tube beam bracket 10 and the instrument panel reinforcing tube beam 20, thereby improving the connection strength and load-bearing capacity of the tube beam bracket 10 on the instrument panel reinforcing tube beam 20.

[0064] It should be noted that, as Figure 2 As shown, in this embodiment, the width of the reinforced folded edge 14 gradually narrows from the third connecting portion 13 to the second connecting portion 12.

[0065] Because the length of the third connecting part 13 is relatively large, and the third connecting part 13 needs to bear the combined force from the first connecting part 11 and the second connecting part 12, while the first connecting part 11 bears the force from the second connecting part 12, the third connecting part 13 has the highest strength, the first connecting part 11 is next, and the second connecting part 12 has the lowest. Therefore, the reinforcing fold 14 is set to gradually narrow based on the structural strength requirements at the corresponding position. This can promote weight reduction while ensuring that the overall structural strength of the tube beam support 10 meets the requirements, which is conducive to achieving the vehicle's strength index.

[0066] For ease of wiring, such as Figure 2 As shown, the reinforcing fold 14 is provided with at least one wire harness connection hole 141. Considering the wiring harness arrangement requirements on the display body 40, the wire harness connection hole 141 is provided on the reinforcing fold 14. This not only facilitates the fixing of the wire harness and prevents the wire harness connected to the display body 40 from shaking and colliding with the tube beam bracket 10 during driving due to lack of restraint, thus avoiding abnormal noise, but also helps to reduce the weight of the tube beam bracket 10, thereby contributing to the overall vehicle lightweighting index.

[0067] Based on the same inventive concept, combined with Figures 1 to 4 It is understood that embodiments of this application also provide an instrument panel assembly, which includes the above-described display screen mounting structure.

[0068] Compared with the prior art, the instrument panel assembly provided in this embodiment adopts the above-mentioned display screen mounting structure. The first connecting part 11 and the second connecting part 12 are provided through the tube beam bracket 10, which can fix the first mounting part 31 on the instrument panel frame 30 to the first connecting part 11. The connecting rib 41 of the display screen body 40 and the second mounting part 32 on the instrument panel frame 30 are connected to the second connecting part 12. This not only allows the display screen body 40 to directly transmit force to the instrument panel reinforcing tube beam 20 through the tube beam bracket 10, thereby avoiding the instrument panel frame 30 bearing the force of the display screen body 40, which is beneficial to improving the installation stability of the instrument panel frame 30 and the display screen body 40 respectively, but also establishes a common connection relationship between the display screen body 40 and the instrument panel frame 30, thereby improving the relative positional accuracy between the display screen body 40 and the instrument panel frame 30, thereby improving the uniformity of the assembly gap and eliminating surface differences, which is beneficial to improving the interior refinement and reducing driving noise problems, thereby improving the vehicle's NVH performance and driving experience.

[0069] Based on the same inventive concept, this application also provides a vehicle including the above-described dashboard assembly.

[0070] Compared with the prior art, the vehicle provided in this embodiment provides a first connecting part 11 and a second connecting part 12 through the tube beam bracket 10. This allows the first mounting part 31 on the instrument panel frame 30 to be fixed to the first connecting part 11. The connecting rib 41 of the display screen body 40 and the second mounting part 32 on the instrument panel frame 30 are jointly connected to the second connecting part 12. This not only allows the display screen body 40 to directly transmit force to the instrument panel reinforcing tube beam 20 through the tube beam bracket 10, thereby avoiding the instrument panel frame 30 bearing the force of the display screen body 40, which is beneficial to improving the installation stability of the instrument panel frame 30 and the display screen body 40 respectively, but also establishes a common connection relationship between the display screen body 40 and the instrument panel frame 30. This improves the relative positional accuracy between the display screen body 40 and the instrument panel frame 30, thereby improving the uniformity of the assembly gap and eliminating surface differences. This is beneficial to improving the interior refinement and reducing driving noise problems, thereby improving the vehicle's NVH performance and driving experience.

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