Description

Technical Field

[0001] The utility model relates to the technical field of cab structures, and more particularly to a side panel support assembly and a cab. Background Art

[0002] At present, people are paying more and more attention to safe travel. Passive safety is an important part of driving safety. The main function of the cab roof is to prevent the passengers' heads from being squeezed when the vehicle rolls over or other safety accidents occur, thereby affecting the passengers' life safety. Therefore, the cab's top pressure strength must meet the design requirements of passive safety.

[0003] The sides of the cab roof include side support beams, one end of which connects to the roof crossbeam and the other to the side longitudinal beams. The side support beams play a key role in providing support and reinforcement between the upper and lower sections. The structural strength of the side support beam connection determines the cab's top pressure resistance. The side support beams are generally connected to the side longitudinal beam outer panels that wrap around the side longitudinal beams.

[0004] In the prior art, there are generally two ways to connect the side panel support beam and the side panel longitudinal beam outer plate: the first is the upper and lower sheet metal butt connection, that is, the lower end of the side panel support beam is connected to the upper end of the side panel longitudinal beam outer plate; the second is the left and right sheet metal overlap connection, that is, the side surface of the side panel support beam is connected to the side surface of the side panel longitudinal beam outer plate.

[0005] The above two connection methods have relatively weak strength at the joints between the side panel support beam and the side panel longitudinal beam outer panel, which can easily cause sheet metal cracking and abnormal noise at this location.

[0006] Therefore, how to improve the structural strength of the joint between the side panel support beam and the side panel longitudinal beam outer panel and reduce the risk of sheet metal cracking and abnormal noise is an urgent problem to be solved by technical personnel in this field.

[0052] The core of this utility model is to provide a side panel support assembly to improve the structural strength of the joint between the side panel support beam and the side panel longitudinal beam outer plate, thereby reducing the risk of sheet metal cracking and abnormal noise.

[0053] Another core of the present invention is to provide a cab having the above-mentioned side support assembly.

[0054] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the scope of the utility model as set forth in the claims. Furthermore, the entire contents of the components described in the following embodiments are not necessarily required to provide the solutions described in the claims. It should be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings. The embodiments and features of the embodiments of the present utility model may be combined with one another unless there is a conflict.

[0055] like Figure 1-Figure 4 As shown, the side panel support assembly disclosed in the embodiment of the present invention is located on both sides of the top of the cab, and is used to support the cab roof to ensure that the cab has the required top pressure strength.

[0056] The side wall support assembly disclosed in this embodiment may include a side wall longitudinal member outer panel 200 and a side wall support body. The upper end of the side wall support body is connected to the cab roof crossbeam 400. The roof crossbeam 400 is arranged transversely on the top of the cab and its ends are connected to the side wall supports on either side of the cab. The two side wall supports secure the roof crossbeam 400. The outer side of the roof crossbeam 400 is used to secure the cab roof.

[0057] The lower end of the side support body is connected to the side longitudinal beam outer plate 200, and the side longitudinal beam outer plate 200 is wrapped with the side longitudinal beam 500. The side support body is a bridge connecting the roof crossbeam 400 and the side longitudinal beam 500, playing a key role in upper and lower connection support and reinforcement.

[0058] Specifically, such as Figure 7 As shown, the upper portion of the side longitudinal beam outer plate 200 has an upper support platform 201, and the outer portion has a side overlap platform 203. It should be noted that the outer portion of the side longitudinal beam outer plate 200 refers to the side of the side longitudinal beam outer plate 200 facing the outside of the cab.

[0059] like Figure 6 and Figure 8 As shown, the lower end of the side support body has an upper connecting platform 602 that cooperates with the upper support platform 201, and a side connecting platform 302 that cooperates with the side lap platform 203. Figure 5 As shown, during installation, the upper connecting platform 602 is attached to and connected to the upper support platform 201. The docking of the upper connecting platform 602 and the upper support platform 201 allows the side longitudinal beams 500 to provide support for the side support bodies. When the cab roof exerts a force on the side support bodies, the force is transferred to the side longitudinal beams 500 through the docking of the side support bodies with the side longitudinal beam outer panels 200.

[0060] The side connecting platforms 302 are attached to and connected to the side bridging platforms 203. When the cab roof is subjected to lateral force, the side connecting platforms 302 and the side bridging platforms 203 are connected to provide support for the cab roof, thereby preventing the connection between the side panel support and the side panel longitudinal beam outer panel 200 from breaking when the cab roof is subjected to lateral force.

[0061] The side panel support assembly disclosed in the embodiment of the present invention is designed with an upper support platform 201 on the upper part of the side panel longitudinal beam outer plate 200 and a side lap platform 203 on the side; at the same time, an upper connection platform 602 and a side connection platform 302 are designed at the lower end of the side panel support. During installation, the upper connection platform 602 is attached to and connected to the upper support platform 201, and the side connection platform 302 is attached to and connected to the side lap platform 203, so that the connection between the side panel support and the side panel longitudinal beam outer plate 200 has both an upper and a lower butt joint connection structure (such as Figure 9 The butt joint structure C shown in FIG) also has a side overlap connection structure (such as Figure 9 The overlapping structure D shown) enables the side support assembly to withstand both lateral forces and vertical forces, has higher connection strength, and reduces the risk of sheet metal cracking and abnormal noise.

[0062] like Figure 5 As shown, in a specific embodiment of the present invention, the side panel support includes a side panel support beam 300 and a side panel support connector 600. The side panel support connector 600 is fixed to the lower end of the side panel support beam 300, and the thickness of the side panel support connector 600 is greater than that of the side panel support beam 300. In this embodiment, the thicker side panel support connector 600 is fixed to the lower end of the side panel support beam 300, thereby increasing the wall thickness of the side panel support where it connects to the side panel outer panel 200.

[0063] Because the required structural strength of the lateral overlap between the side panel support and the side panel longitudinal outer panel 200 is lower than that of the upper and lower joints, the side connection platform 302 can be located at the lower end of the side panel support beam 300, which has a thinner wall. The upper connection platform 602 is located at the lower end of the side panel support connector 600, which has a thicker wall.

[0064] This embodiment adds a side panel support connecting seat 600 to the side panel support beam 300 to strengthen the connection between the side panel support beam 300 and the side panel longitudinal beam outer panel 200. While meeting the top pressure strength, the side panel support connecting seat 600 is added in the area with poor local rigidity to ensure that the vehicle body structure is fatigue-resistant and reliable during use, and no local cracks, abnormal noises or other problems will occur during the product life cycle.

[0065] In order to meet the required cab top pressure strength, the present invention uses CAE (Computer Aided Engineering) analysis to verify the weak area at the junction of the side panel support body and the side panel longitudinal beam outer panel 200, and adds a side panel support connecting seat 600 (a smaller part) instead of changing the material thickness of the side panel support beam 300 (a larger part). This achieves optimal cost while reducing weight.

[0066] like Figure 8 As shown, in this embodiment, the side panel support connector 600 includes a mounting slot 601 with openings at the top, bottom, and one side. Specifically, the top, bottom, and one side of the mounting slot 601 are all open. The upper connecting platform 602 is located at the bottom of the mounting slot 601 and is connected to the upper support platform 201 via the bottom of the mounting slot 601.

[0067] The lower end of the side support beam 300 is embedded in the embedded groove 601 and welded to the embedded groove 601, that is, it is welded to the side support beam 300 through the side opening of the embedded groove 601. The embedded groove 601 is in a surrounding shape, wrapped around the outer side of the lower end of the side support beam 300, and the side support connecting seat 600 is welded to the side support beam 300. Specifically, the upper connecting platform 602 can be welded to the upper support platform 201 (such as Figure 9 The side opening of the embedded slot 601 is welded to the side support beam 300 (see welding point B). Figure 9 The side connection platform 302 may also be welded to the side landing 203 (weld point B shown).

[0068] The welding disclosed in this embodiment can be spot welding, a type of resistance welding method that primarily utilizes a cylindrical electrode to form a weld spot between the contact surfaces of two overlapping workpieces. This welding method is particularly suitable for welding thin sheet metal stampings with a total thickness of less than 5.5 mm. It is characterized by high welding speeds and can significantly improve production efficiency.

[0069] The upper connecting platform 602 is formed by bending the lower end of the embedded groove body 601 outward. This configuration allows the upper connecting platform 602 to have a larger area than the end surface of the embedded groove body 601, thereby allowing the upper connecting platform 602 to have a larger contact area with the upper support platform 201, and the docking strength is higher.

[0070] like Figure 6 As shown, the lower end of the side panel support beam 300 has an inclined docking surface 301. The height of the inclined docking surface 301 on the inner side of the side panel support beam 300 is higher than the height of the inclined docking surface 301 on the outer side of the side panel support beam 300. In other words, the inclined docking surface 301 extends obliquely from the side connecting platform 302 toward the inner side of the side panel support beam 300.

[0071] like Figure 7 As shown, to increase the contact area between the side panel support beam 300 and the side panel outer panel 200, the upper portion of the side panel outer panel 200 has an inclined docking platform 202 connecting the upper support platform 201 and the side lap platform 203. The inclined docking surface 301 mates with the inclined docking platform 202. When the side panel support beam 300 is installed on the side panel outer panel 200, the inclined docking surface 301 of the side panel support beam 300 mates with the inclined docking platform 202 of the side panel outer panel 200, and the side connecting platform 302 of the side panel support beam 300 mates with the side lap platform 203 of the side panel outer panel 200. The larger contact area between the side panel support beam 300 and the side panel outer panel 200 provides a higher connection strength. Furthermore, the inclined docking surface 301 and the inclined docking platform 202 can withstand both vertical and horizontal forces.

[0072] like Figure 2 As shown, in a specific embodiment of the present invention, the upper support platform 201 is formed by a downward depression in the upper surface of the side panel outer panel 200. That is, the upper surface of the side panel outer panel 200 is depressed downward to form the upper support platform 201, so that the upper support platform 201 is located within a groove. After the upper connecting platform 602 is docked with the upper support platform 201, the upper connecting platform 602 sinks into the groove where the upper support platform 201 is located. In this embodiment, by forming the upper support platform 201 with a downward depression, a relatively flat surface is created for docking with the upper connecting platform 602 without affecting the upper surface shape of the side panel outer panel 200, thereby achieving higher docking strength.

[0073] The side lap 203 is formed by an inward depression on the outer surface of the side longitudinal beam outer panel 200. Specifically, the outer surface of the side longitudinal beam outer panel 200 is recessed inward to form the side lap 203, so that the side lap 203 is located within a groove. After the side connection platform 302 is docked with the side lap 203, the side connection platform 302 sinks into the groove where the side lap 203 is located. In this embodiment, by forming the side lap 203 with an inward depression, a relatively flat surface is created for docking with the side connection platform 302 without affecting the outer surface shape of the side longitudinal beam outer panel 200, thereby achieving higher docking strength. Furthermore, the side connection platform 302 is sunk into the groove where the side lap 203 is located, and the sidewalls of the groove limit the side connection platform 302, providing a certain force-bearing capacity in the fore-aft direction and resisting deformation to a certain extent.

[0074] The inclined docking platform 202 is formed by an inward depression at the junction of the upper support platform 201 and the side overlap platform 203. This configuration allows the lower end of the side panel support to be sunken into the groove of the side panel longitudinal beam outer panel 200, which can help to position the side panel support and the side panel longitudinal beam outer panel 200 and facilitate subsequent welding.

[0075] like Figure 1-Figure 3 As shown, the side panel upper outer panel 100 is provided on the outer side of the side panel support beam 300, and is located above the side panel longitudinal outer panel 200. Both the side panel upper outer panel 100 and the side panel longitudinal outer panel 200 are thin panel moldings that can optimize the sealing effect of the entire vehicle.

[0076] In a specific embodiment of the present invention, the thickness of the side panel upper outer panel 100 is 0.7mm-1.2mm; the thickness of the side panel longitudinal beam outer panel 200 is 0.7mm-1.2mm; the thickness of the side panel support beam 300 is 0.8mm-1.6mm; and the thickness of the side panel support connector 600 is 1.2mm-2.0mm. It should be noted that the above panel thickness ranges are only one specific embodiment. Those skilled in the art may adjust the panel thickness based on different vehicle models and design objectives, and are not limited to the thickness ranges disclosed in the above embodiment.

[0077] The embodiment of the present utility model further discloses a cab, which includes the side wall support assembly disclosed in the above embodiment. Since it has the above side wall support assembly, it has all the technical effects of the above side wall support assembly, which will not be described in detail herein.
