Description

Technical Field

[0001] This application relates to the field of vehicle chassis technology, and in particular to a shock absorber bracket, a frame assembly, and a vehicle. Background Technology

[0002] Currently, in rigid axle vehicles, the shock absorber bracket is located on the longitudinal beam of the chassis assembly, and the shock absorber bracket needs to bear the load transmitted to the suspension from the road side.

[0003] In related technologies, the layout of the shock absorber bracket and its surrounding devices (such as the steering column) in the vehicle frame assembly is affected, which limits the contact area between the shock absorber bracket and the longitudinal beam. As a result, the structural strength and fatigue strength of the connection area between the shock absorber bracket and the longitudinal beam are relatively weak. If the vehicle is driving in off-road conditions or on bumpy roads, there is a risk of cracking and severe deformation at the connection between the shock absorber bracket and the longitudinal beam, which can easily lead to vehicle failure. Utility Model Content

[0012] According to some embodiments of this application, the damper bracket reinforcing plate is provided with a first damper bracket reinforcing plate connecting flange, which is bent away from the longitudinal beam and connected to the third damper bracket plate segment.

[0013] According to some embodiments of this application, the cross-sectional dimension of the second cavity in the Y direction gradually increases from the inside to the outside, so as to form a clearance area at the upper part of the second cavity of the damper bracket body.

[0046] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0047] In the description of this application, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0048] In the description of this application, the terms "above," "over," and "on top" for the first feature and the second feature include the first feature being directly above or diagonally above the second feature, or simply indicate that the first feature is at a higher horizontal level than the second feature.

[0049] The following will refer to the appendix. Figure 1 - Figure 8 The shock absorber bracket 8 of this application embodiment will be described in detail with reference to the embodiments. The shock absorber bracket 8 is disposed on the frame assembly 100 and is connected and cooperated with the longitudinal beam 1 of the frame assembly 100.

[0050] According to an embodiment of this application, the vibration damper bracket 8 includes: a vibration damper bracket body 81, a vibration damper mounting plate 82, and a vibration damper bracket reinforcing plate 83.

[0051] Combination Figure 2 and Figure 4As shown, the damper bracket body 81 is connected to the longitudinal beam 1, and the damper mounting plate 82 is connected to the damper bracket body 81. The damper mounting plate 82 is used to cooperate with the damper bracket body 81 to install the damper, so as to realize the installation cooperation between the damper bracket 8 and the damper.

[0052] Furthermore, the damper bracket reinforcing plate 83 in the damper bracket 8 is disposed on the outside of the longitudinal beam 1, and the damper bracket reinforcing plate 83 is connected to the damper bracket body 81 and the longitudinal beam 1 respectively, so as to form a second cavity 801 by the damper bracket body 81, the damper bracket reinforcing plate 83 and the longitudinal beam 1.

[0053] Combination Figure 2 , Figure 7 as well as Figure 8 As shown, in the damper bracket 8, the damper bracket body 81 is connected and fitted with the longitudinal beam 1, and the damper bracket reinforcing plate 83 is set in the vertical direction. The damper bracket reinforcing plate 83 is connected and fitted with the damper bracket body 81 and the longitudinal beam 1 respectively, and encloses to form a second cavity 801, so as to improve the structural strength of the damper bracket body 81, the damper bracket reinforcing plate 83 and the longitudinal beam 1 through the cavity structure.

[0054] The second cavity 801 is arranged vertically in relation to the longitudinal beam 1.

[0055] Combination Figure 2 , Figure 4 and Figure 7 As shown, after the shock absorber bracket 8 is installed and fitted with the longitudinal beam 1, part of the shock absorber bracket body 81 is located above the longitudinal beam 1, and the shock absorber bracket body 81 is connected and fitted with the shock absorber mounting plate 82 to form a shock absorber mounting structure on the upper part of the shock absorber bracket 8. The shock absorber bracket reinforcing plate 83 is set on the outside of the longitudinal beam 1. Through the cooperation of the shock absorber reinforcing plate with the shock absorber bracket body 81 and the longitudinal beam 1, the deformation resistance of the shock absorber bracket body 81 relative to the longitudinal beam 1 is improved.

[0056] It is understood that the second cavity 801 is formed above the longitudinal beam 1, and is defined by the wall of the damper bracket body 81, the upper wall of the longitudinal beam 1, and the wall of the damper bracket reinforcing plate 83. That is, at least part of the damper bracket body 81 and at least part of the damper bracket reinforcing plate 83 are located in the area above the longitudinal beam 1, and both the damper bracket body 81 and the damper bracket reinforcing plate 83 extend to the longitudinal beam 1 to enclose and form the aforementioned second cavity 801.

[0057] When the damper bracket reinforcement plate 83 is connected and fitted with the damper bracket body 81 and the longitudinal beam 1 to form the second cavity 801, the damper bracket 8 has good anti-deformation performance in the second cavity 801. This can reduce the deformation of the plate structure (such as the damper bracket body 81 and the damper bracket reinforcement plate 83) in the damper bracket 8, which could lead to cracking at the fit between the damper bracket 8 and the longitudinal beam 1.

[0058] Currently, in front solid axle models, the shock absorber bracket 8 is installed at the longitudinal beam 1 of the frame assembly 100, and the shock absorber bracket 8 needs to bear the load transmitted to the suspension from the road side.

[0059] In related technologies, the layout of surrounding devices (such as the steering column) within the frame assembly 100 affects the shock absorber bracket 8, resulting in a limited contact area between the shock absorber bracket 8 and the longitudinal beam 1. This leads to weaker structural and fatigue strength in the connection area between the shock absorber bracket 8 and the longitudinal beam 1. If the vehicle is traveling in off-road conditions or on bumpy roads, there is a risk of severe cracking and deformation at the connection point between the shock absorber bracket 8 and the longitudinal beam 1, which can easily cause vehicle malfunctions. Furthermore, in existing technologies, the installation position of the shock absorber bracket 8 relative to the shock absorber is higher than that of the longitudinal beam 1, further exacerbating the stress conditions at the shock absorber bracket 8 and increasing the risk of cracking and deformation.

[0060] According to the embodiments of this application, the shock absorber bracket 8 is composed of three parts: a shock absorber bracket body 81, a shock absorber mounting plate 82, and a shock absorber bracket reinforcing plate 83. The shock absorber bracket body 81 and the shock absorber mounting plate 82 are connected and cooperate to form an installation structure in the shock absorber bracket 8 for installation and cooperation with the shock absorber. By connecting the shock absorber bracket reinforcing plate 83 to the shock absorber bracket body 81 and the longitudinal beam 1 respectively, the connection strength between the shock absorber bracket body 81 and the longitudinal beam 1 is further improved. Moreover, the shock absorber bracket reinforcing plate 83, the shock absorber bracket body 81, and the longitudinal beam 1 enclose a second cavity 801. The setting of the second cavity 801 can improve the deformation resistance of the shock absorber bracket body 81 and the shock absorber bracket reinforcing plate 83 relative to the longitudinal beam 1, ensure the connection reliability between the shock absorber bracket 8 and the longitudinal beam 1, and the performance of the shock absorber bracket 8 in bearing the load on the road side.

[0061] Reference Figure 7As shown, in some embodiments of this application, the cross-sectional dimension of the second cavity 801 in the Y direction gradually increases from the inside to the outside, thereby constructing the second cavity 801 as a cavity structure that gradually expands outward in the Y direction, such as a cavity structure with a roughly triangular cross-section. This allows the second cavity 801 to form a more stable support in the area where the shock absorber bracket 8 and the longitudinal beam 1 meet, improving the connection strength between the shock absorber bracket 8 and the longitudinal beam 1 and reducing the risk of cracking at the connection between the shock absorber bracket 8 and the longitudinal beam 1. Simultaneously, a clearance area can be formed above the second cavity 801 in the shock absorber bracket body 81 to ensure the connection effect between the shock absorber bracket 8 and the longitudinal beam 1 while avoiding obstacles above the longitudinal beam 1.

[0062] Understandably, in the frame assembly 100, part of the steering column is located in the area above the longitudinal beam 1, and the shock absorber bracket body forms a clearance area above the second cavity 801, which can clear the steering column.

[0063] like Figure 8 As shown, in some embodiments of this application, the damper bracket body 81 includes: a first damper bracket plate segment 811, a second damper bracket plate segment 812, and a third damper bracket plate segment 813.

[0064] The first damper support plate segment 811 is connected to the longitudinal beam 1. The second damper support plate segment 812 and the third damper support plate segment 813 are respectively connected to the two sides of the first damper support plate segment 811 in the X direction. The second damper support plate segment 812 and the third damper support plate segment 813 are arranged opposite to each other in the X direction. The damper mounting plate 82 is connected to the second damper support plate segment 812 and the third damper support plate segment 813 respectively.

[0065] It should be noted that the "X-direction" mentioned above refers to the front-rear direction of the frame assembly 100. The "X-direction" and "Y-direction" in this application are defined as the direction in which the shock absorber bracket 8 is applied in the frame assembly 100, that is, the "Y-direction" is the left-right direction of the frame assembly 100.

[0066] Combination Figure 2 and Figure 8 As shown, when the shock absorber bracket 8 is installed in the frame assembly 100, the second shock absorber bracket plate segment 812 and the third shock absorber bracket plate segment 813 are arranged opposite to each other and spaced apart in the front-rear direction, and the second shock absorber bracket plate segment 812 and the third shock absorber bracket plate segment 813 are connected through the first shock absorber bracket plate segment 811.

[0067] The vibration damper mounting plate 82 is arranged along the X-direction, and the vibration damper mounting plate 82 is connected and cooperated with the second vibration damper bracket plate segment 812 and the third vibration damper bracket plate segment 813 at both ends in the X-direction, respectively. Moreover, the vibration damper mounting plate 82 is opposite to and spaced apart from the first vibration damper bracket plate segment 811 in the Y-direction, so as to form a vibration damper mounting structure by cooperating with the first vibration damper bracket plate segment 811.

[0068] It is understood that the shock absorber bracket body 81 is composed of three plate segments (i.e., the first shock absorber bracket plate segment 811, the second shock absorber bracket plate segment 812, and the third shock absorber bracket plate segment 813 mentioned above), and these three plate segments define a groove structure that opens outward in the Y direction, thereby creating space for the shock absorber at the shock absorber bracket body 81. Furthermore, some of the shock absorber bracket reinforcing plates 83 can be arranged within the groove structure and connected to the first shock absorber bracket plate segment 811. Simultaneously, the groove structure formed by the shock absorber bracket body 81 can also be used to accommodate a nitrogen tank in the vehicle, thereby improving the space utilization rate at the shock absorber bracket 81.

[0069] Combination Figure 2 and Figure 8 As shown in a further embodiment of this application, the second damper bracket plate segment 812 has a first damper bracket flange 8121 at the end away from the first damper bracket plate segment 811 in the Y direction. The first damper bracket flange 8121 is folded from the second damper bracket plate segment 812 toward the side away from the third damper bracket plate segment 813. The third damper bracket plate segment 813 has a second damper bracket flange 8131 at the end away from the first damper bracket plate segment 811 in the Y direction. The second damper bracket flange 8131 is folded from the third damper bracket plate segment 813 toward the side away from the second damper bracket plate segment 812.

[0070] It is understandable that by further adding a flange structure at the edge of the plate segment, the deformation resistance of the plate segment can be improved and the risk of deformation can be reduced.

[0071] The first damper bracket flange 8121 is connected to the end of the second damper bracket plate segment 812 (i.e., the end of the second damper bracket plate segment 812 away from the first damper bracket plate segment 811 in the Y direction), thereby improving the deformation resistance of the second damper bracket plate segment 812. The second damper bracket flange 8131 is connected to the end of the third damper bracket plate segment 813 (i.e., the end of the third damper bracket plate segment 813 away from the first damper bracket plate segment 811 in the Y direction), thereby improving the deformation resistance of the third damper bracket plate segment 813. This enhances the structural strength of the damper bracket 8 mounting body, providing a reliable mounting structure for the damper mounting plate 82.

[0072] Combination Figure 2 and Figure 8 As shown, in some embodiments of this application, the vibration damper mounting plate 82 includes: a first vibration damper mounting plate segment 821, a second vibration damper mounting plate segment 822, and a third vibration damper mounting plate segment 823.

[0073] The first damper mounting plate segment 821 is positioned opposite to the first damper bracket plate segment 811, and the first damper mounting plate segment 821 and the first damper bracket plate segment 811 cooperate to connect with the damper; the second damper mounting plate segment 822 is connected to the second damper bracket plate segment 812; and the third damper mounting plate segment 823 is connected to the flange 8131 of the second damper bracket. This achieves a connection between the damper mounting plate 82 and the damper bracket body 81, and forms an installation structure for mounting the damper within the damper bracket 8.

[0074] Combination Figure 2 and Figure 8 As shown, the first damper mounting plate segment 821 and the first damper bracket plate segment 811 are arranged opposite each other in the Y direction, and the mounting structure for damper installation can be formed by opening holes in the first damper mounting plate 821 and the first damper bracket plate segment 811.

[0075] Meanwhile, the damper mounting plate 82 can be connected and fixed to the damper bracket body 81 through the second damper mounting plate segment 822 and the third damper mounting plate segment 823, respectively. Specifically, the second damper mounting plate segment 822 is fitted and connected to the second damper bracket plate segment 812, and the third damper mounting plate segment 823 is fitted and connected to the second damper bracket flange 8131. This increases the contact area and reliably fixes the damper mounting plate 82 to the damper bracket body 81.

[0076] Specifically, the second damper mounting plate segment 822 is bent outward relative to the first damper mounting plate 82, and the second damper mounting plate segment 822 is fitted and fixedly connected to the second damper bracket plate segment 812 in the front-rear direction; the third damper mounting plate 82 extends further rearward relative to the first damper mounting plate 82, and the third damper mounting plate segment 823 is fitted and fixedly connected to the second damper bracket flange 8131 in the inside-out direction. Thus, the damper mounting plate 82 is connected and fitted to the damper bracket body 81 in two directions, with the two directions having an included angle (e.g., 90°), to further improve the reliability of the fit between the damper mounting plate 82 and the damper bracket body 81.

[0077] Combination Figure 2 and Figure 8 As shown, the shock absorber mounting plate 82 is installed and cooperated with the shock absorber bracket body 81 to form a ring-shaped mounting structure on the upper part of the shock absorber bracket 8. The shock absorber can be connected to two oppositely arranged plate segments (i.e., the first shock absorber bracket plate segment 811 and the first shock absorber mounting plate segment 821) in the ring-shaped mounting structure to improve the reliability of the connection between the shock absorber bracket 8 and the shock absorber.

[0078] In a further embodiment of this application, the first damper mounting plate segment 821 is formed with a raised plate segment 8211 protruding in the Y direction away from the first damper support plate segment 811. The raised plate segment 8211 can further improve the structural strength of the first damper mounting plate segment 821, thereby improving the local strength of the mounting structure of the damper support 8 for mounting the damper. The hole structure in the first damper mounting plate segment 821 for mounting and mating with the damper can be formed on the raised plate segment 8211. Simultaneously, the raised plate segment 8211 also helps to improve the positional accuracy of the mounting point.

[0079] Combination Figure 2 and Figure 8 As shown, in some embodiments of this application, the third damper bracket plate segment 813 is provided with an arc-shaped clearance notch 8132 on the side away from the first damper bracket plate segment 811. The arc-shaped clearance notch 8132 is located at the lower part of the connection and mating point between the third damper bracket plate segment 813 and the damper mounting plate 82. The arc-shaped clearance notch 8132 is recessed from one end of the third damper bracket plate segment 813 in the Y direction (the end of the third damper bracket plate segment 813 away from the first damper bracket plate segment 811 in the Y direction) toward the side of the first damper bracket plate segment 811. This allows the device (such as a nitrogen tank) arranged inside the groove structure formed by the damper bracket body 81 to be avoided, thereby improving the space utilization rate of the damper bracket 8 while avoiding interference between the damper bracket body 81 and its surrounding devices.

[0080] Combination Figure 5 and Figure 8 As shown, in some embodiments of this application, the first damper bracket plate segment 811 is provided with a damper bracket reinforcing rib 8111, and the damper bracket reinforcing rib 8111 is located on the side where the first damper bracket plate segment 811 is connected to the third damper bracket plate segment 813. The damper bracket reinforcing rib 8111 extends vertically and is corresponding to at least a portion of the arc-shaped clearance notch 8132 in the vertical direction, so as to further improve the structural strength of the damper bracket body 81 through the damper bracket reinforcing rib 8111.

[0081] Specifically, the damper bracket reinforcing rib 8111 protrudes from the plate section area of ​​the first damper bracket plate section 811 used for installation with the damper, so as to form a reinforcing structure on the first damper bracket plate section 811 and improve the local deformation resistance of the first damper bracket plate section 811.

[0082] It is understandable that an arc-shaped clearance notch 8132 is formed on the third shock absorber bracket plate segment 813. The shock absorber bracket reinforcing rib 8111 is arranged vertically in correspondence with the clearance notch, which can further improve the strength of the third shock absorber bracket plate segment 813. Moreover, the design of the arc-shaped clearance notch 8132 can effectively prevent stress concentration and reduce the risk of cracking of the shock absorber bracket body 81.

[0083] Combination Figure 2 and Figure 8 As shown, in some embodiments of this application, the damper bracket reinforcing plate 83 is provided with a first damper bracket reinforcing plate connecting flange 831, the first damper bracket reinforcing plate connecting flange 831 is bent away from the longitudinal beam 1, and the first damper bracket reinforcing plate connecting flange 831 is connected to the third damper bracket plate segment 813.

[0084] Specifically, the first damper bracket reinforcing plate connecting flange 831 is located at the rear of the damper bracket reinforcing plate 83, and the first damper bracket reinforcing plate connecting flange 831 is bent outward, so that the first damper bracket reinforcing plate connecting flange 831 is opposite to and connected to the third damper bracket plate segment 813 in the front-back direction. The first damper bracket reinforcing plate connecting flange 831 can be fitted and welded to the third damper bracket plate segment 813.

[0085] Combination Figure 2 and Figure 8As shown, part of the third damper bracket plate segment 813 extends downward to the area corresponding to the longitudinal beam 1, and can be connected and cooperated with the connecting flange 831 of the first damper bracket reinforcing plate. By cooperating with the connecting flange of the first damper reinforcing plate through the third damper bracket plate segment 813, the connection and cooperation area between the damper bracket body 81 and the damper bracket reinforcing plate 83 is further increased, thereby improving the connection reliability between the damper bracket body 81 and the damper bracket reinforcing plate 83.

[0086] In some embodiments of this application, the inner end of the damper bracket body 81 overlaps with the longitudinal beam 1, and the inner end of the damper bracket body 81 extends toward the inner sidewall of the longitudinal beam 1 to increase the contact area between the damper bracket body 81 and the longitudinal beam 1 and improve the connection strength between the damper bracket body 81 and the longitudinal beam 1.

[0087] The shock absorber bracket 8 according to the embodiments of this application has at least the following advantages compared to the prior art:

[0088] (1) The damper bracket 8 is fitted with the damper mounting plate 82 through the damper bracket body 81 to form an installation structure for installing the damper. The damper bracket 8 is provided with a damper bracket reinforcing plate 83. The damper bracket reinforcing plate 83 is connected to the damper bracket body 81 and the longitudinal beam 1 respectively to form a double plate structure in the corresponding area of ​​the damper bracket reinforcing plate 83 and the damper bracket body 81. A second cavity 801 is formed between the damper bracket body 81, the damper bracket reinforcing plate 83 and the longitudinal beam 1. The setting of the second cavity 801 can further improve the deformation resistance of the damper bracket 8 relative to the longitudinal beam 1.

[0089] (2) An arc-shaped clearance notch 8132 is formed on the main body 81 of the shock absorber bracket. The arc-shaped clearance notch 8132 can avoid devices (such as nitrogen tanks) arranged around the shock absorber bracket 8. The structural strength of the main body 81 of the shock absorber bracket can be further improved by the first shock absorber bracket flange 8121 and the second shock absorber bracket flange 8131.

[0090] (3) A clearance area is formed above the second cavity 801 on the main body 81 of the shock absorber bracket. The clearance area can clear the device (such as the steering column) above the longitudinal beam 1.

[0091] The frame assembly 100 according to an embodiment of this application includes the shock absorber bracket 8 described above.

[0092] Combination Figure 4 and Figure 8As shown, in some embodiments of this application, the frame assembly 100 further includes a coil spring support 7, which is disposed on the longitudinal beam 1 and located on the front side of the shock absorber bracket 8. The shock absorber bracket body 81 is provided with a third shock absorber bracket flange 8122, which overlaps on the coil spring support 7 and is connected to the coil spring support 7.

[0093] Reference Figure 4 The third damper bracket flange 8122 overlaps and connects with the coil spring support 7, thereby increasing the contact area between the damper bracket 8 and the coil spring support 7. By increasing the contact area, the stiffness of the damper bracket 8 is improved, and the damper bracket 8 and the coil spring support 7 can be constructed as a whole, thus improving the overall structural strength of the damper bracket 8 and the coil spring support 7.

[0094] Combination Figure 2 and Figure 8 As shown, in some embodiments of this application, the damper bracket reinforcing plate 83 is provided with a second damper bracket reinforcing plate connecting flange 832, which is arranged vertically and connected to the damper bracket body 81 and the coil spring support 7 respectively.

[0095] The second damper bracket reinforcing plate connecting flange 832 is located at the front of the damper bracket reinforcing plate 83, and the second damper bracket reinforcing plate connecting flange 832 is bent outward. Moreover, the second damper bracket reinforcing plate connecting flange 832 is arranged vertically in correspondence with part of the second damper bracket plate segment 812 and part of the coil spring support 7 of the damper bracket body 81. Thus, the setting of the second damper bracket reinforcing plate connecting flange 832 increases the contact area between the damper bracket body 81 and the damper bracket reinforcing plate 83, and between the damper bracket reinforcing plate 83 and the coil spring support 7. This improves the strength of the damper bracket 8 itself and enhances the fit strength between the damper bracket 8 and the coil spring support 7.

[0096] like Figure 4 As shown, in some embodiments of this application, the frame assembly 100 also includes an engine mount 9, which is disposed on the longitudinal beam 1 and located on the rear side of the shock absorber bracket 8. Part of the engine mount 9 is disposed vertically between the shock absorber bracket body 81 and the longitudinal beam 1. The engine mount 9 is connected to the lower edge of the shock absorber bracket body 81 to be supported on the bottom of the shock absorber bracket body 81.

[0097] The engine mount 9 is used to mount and mate with the engine to suspend the engine. Part of the shock absorber mount 8 can be supported and connected to the engine mount 9, thereby connecting the shock absorber mount 8 and the engine mount 9 to increase the contact area between them. This increases the local stiffness of the shock absorber mount 8 and allows the shock absorber mount 8 and the engine mount 9 to be constructed as a whole, thus improving the overall structural strength of the structure formed by the shock absorber mount 8 and the engine mount 9.

[0098] It is understood that in the vehicle frame assembly 100 of this application embodiment, the coil spring support 7, the shock absorber bracket 8, and the engine mount bracket 9 are all arranged on the longitudinal beam 1, and the coil spring support 7, the shock absorber bracket 8, and the engine mount bracket 9 are arranged sequentially from front to back. Moreover, the front and rear sides of the shock absorber bracket 8 are connected and cooperated with the front suspension spring and the engine mount bracket 9 respectively, thereby making the coil spring support 7, the shock absorber bracket 8, and the engine mount bracket 9 a whole, which helps to improve the overall strength of the bracket structure in the corresponding area of ​​the suspension in the vehicle frame assembly 100.

[0099] The vehicle according to an embodiment of this application includes the frame assembly 100 described above.

[0100] The vehicle described above has the same advantages as the aforementioned chassis assembly 100 compared to existing technologies, which will not be repeated here.

[0101] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
