Suspension structure and vehicle

Abstract

This invention relates to a suspension structure and a vehicle. The suspension structure supports a radiator assembly of a vehicle. The radiator assembly has a mounting portion on one side along a first direction. The suspension structure includes a suspension bracket, one end of which has a mounting groove that mates with the mounting portion. The mounting groove restricts the position of the radiator assembly along a second direction. The other end of the suspension bracket is connected to the vehicle frame. The first direction is perpendicular to the second direction. This suspension structure, by providing a suspension bracket with a mounting groove and a mounting portion that mates with the mounting groove in the radiator assembly, allows the mounting portion to be positioned within the mounting groove when connecting the radiator assembly to the vehicle frame. Fasteners are then used to connect and secure the suspension bracket to the radiator assembly and the vehicle frame. This simplifies operation and improves the installation efficiency of the radiator assembly.

Description

Technical Field

[0001] This invention relates to the field of radiator mounting system technology, and in particular to a mounting structure and vehicle. Background Technology

[0002] The radiator mounting system is an important component of a vehicle. The radiator assembly is connected to the chassis through the radiator mounting system, which also serves to support the radiator assembly and reduce vibrations transmitted from the chassis to the radiator assembly.

[0003] The radiator assembly is usually fixed to the vehicle frame through mounting holes on the side plate of the radiator assembly. The inner width of the frame of a light commercial vehicle is relatively narrow. After the radiator assembly is installed on the frame, due to the limited line of sight and space, it takes a long time to adjust the position of the radiator assembly to align the mounting holes, resulting in low installation efficiency. Summary of the Invention

[0021] In one embodiment, the dimension of the second segment connecting one end of the first segment along the first direction in the second direction increases from the direction close to the first segment to the direction away from the first segment.

[0022] The diameter of the first mounting hole at the end opposite to the heat sink assembly along the first direction increases from the direction closer to the first segment to the direction farther away from the first segment.

[0055] See Figures 1 to 3 and combined Figure 7 This application provides a suspension structure 10 for supporting a vehicle's radiator assembly 20, the radiator assembly 20 being positioned along a first direction (e.g., Figure 1 The mounting structure 10 (shown as X in the figure) has a mounting part 22 on one side, and the suspension structure 10 includes a suspension bracket 11. One end of the suspension bracket 11 has a mounting groove 111 that mates with the mounting part 22 (see Figure 10). Figures 5 to 7 Mounting slot 111 is used to limit the radiator assembly 20 along a second direction (e.g., Figure 1 At the position shown in the diagram (Y), the other end of the suspension bracket 11 is connected to the vehicle frame 30. The first direction is perpendicular to the second direction.

[0056] Thus, the suspension structure 10 of this application, by setting a suspension bracket 11 with a mounting groove 111 and a radiator assembly 20 with a mounting part 22 that mates with the mounting groove 111, allows the mounting part 22 to be positioned within the mounting groove 111 when connecting the radiator assembly 20 to the vehicle frame 30. The suspension bracket 11 and the radiator assembly 20, as well as the suspension bracket 11 and the vehicle frame 30, are then connected and fixed by fasteners. This method is simple to operate and helps improve the installation efficiency of the radiator assembly 20.

[0057] See Figures 3 to 6The suspension bracket 11 is generally L-shaped and includes a first bracket 112 and a second bracket 113, one end of which is connected to one end of the first bracket 112. The first bracket 112 extends along a second direction, and the end of the first bracket 112 away from the second bracket 113 along the second direction is connected to the radiator assembly 20. The second bracket 113 extends along a first direction, and the end of the second bracket 113 away from the first bracket 112 along the first direction is connected to the vehicle frame 30. A mounting groove 111 is provided at the connection between the first bracket 112 and the second bracket 113.

[0058] Thus, by setting the matching mounting slot 111 and mounting part 22, the installation position of the radiator assembly 20 can be determined, enabling the radiator assembly 20 to adaptively adjust its posture, which also helps to improve the installation efficiency of the radiator assembly 20 and the frame 30. Since the machining accuracy of the mounting slot 111 and mounting part 22 is controllable, as long as the machining accuracy of the mounting slot 111 and mounting part 22 is guaranteed, the installation accuracy of the radiator assembly 20 can be guaranteed. The mounting slot 111 can also restrict the position of the mounting part 22, thereby determining the position of the radiator assembly 20, avoiding the need to repeatedly align the mounting holes to determine the installation position of the radiator assembly 20 during the installation process, thus saving installation time.

[0059] See Figure 1 and Figure 2 The radiator assembly 20 includes a radiator body 21 and a mounting part 22 that connects to the radiator body 21.

[0060] See Figures 5 to 7 The first bracket 112, located away from the second bracket 113 along the second direction, has a first mounting hole 1121 extending along the first direction. The radiator body 21 has a second mounting hole 211 extending along the first direction. The suspension structure 10 also includes a first fastener 12 and a second fastener 13. The first fastener 12 is installed on the side of the radiator assembly 20 away from the mounting portion 22 along the first direction, and the first fastener 12, the first mounting hole 1121, and the second mounting hole 211 are correspondingly arranged, that is, the axes of the first fastener 12, the first mounting hole 1121, and the second mounting hole 211 are coincidentally arranged. The second fastener 13 extends into the first mounting hole 1121 and the second mounting hole 211 in sequence and is fastened to the first fastener 12.

[0061] Further, see Figure 7The first fastener 12 has a connecting hole 121, and the wall of the connecting hole 121 has an internal thread. The second fastener 13 includes a first segment 131, a second segment 132, and a third segment 133 connected in sequence. The first segment 131 extends into the first mounting hole 1121 and the second mounting hole 211 in sequence, and the outer peripheral surface of the first segment 131 has an external thread that mates with the connecting hole 121. The second segment 132 passes through the first bracket 112. The third segment 133 is located on the side of the first bracket 112 away from the radiator assembly 20 along the first direction, and is located outside the first bracket 112 to restrict the position of the second fastener 13. The dimension of the first segment 131 in the second direction is smaller than that of the second segment 132 in the second direction, the dimension of the second segment 132 in the second direction is smaller than that of the third segment 133 in the second direction, and the dimension of the third segment 133 in the second direction is larger than the diameter of the first mounting hole 1121 to restrict the position of the second fastener 13. Optionally, the first fastener 12 is a nut with internal threads, and the second fastener 13 is a bolt with external threads at one end.

[0062] Thus, by setting the first fastener 12 and the second fastener 13 to connect the radiator assembly 20 and the suspension bracket 11, the connection is simple and reliable; and the outer diameters of the first segment 131, the second segment 132 and the third segment 133 are different so that the second fastener 13 can be adapted to the first mounting hole 1121, the second mounting hole 211 and the connecting hole 121, and the position of the second fastener 13 is restricted.

[0063] Furthermore, the dimension of the second segment 132, which connects to one end of the first segment 131 along the first direction, increases along the first direction from near to far from the first segment 131; the diameter of the first mounting hole 1121, which is away from the heat sink assembly 20 along the first direction, increases along the first direction from near to far from the first segment 131; and the end of the second segment 132 that connects to the first segment 131 along the first direction mates with the end of the first mounting hole 1121 that is away from the heat sink assembly 20 along the first direction.

[0064] It should be noted that the second segment 132 has a chamfer at one end connecting to the first segment 131 along the first direction, and the first mounting hole 1121 also has a corresponding chamfer. The purpose of these two chamfers is to correct the machining errors of the first mounting hole 1121, the second mounting hole 211, and the connecting hole 121 when the heat sink assembly 20 and the first bracket 112 are connected by the second fastener 13, so as to make the axes of the first mounting hole 1121, the second mounting hole 211, the connecting hole 121, and the second fastener 13 coincide, so as to perform a secondary adaptive adjustment of the posture of the heat sink assembly 20 (relative to the primary adaptive adjustment of the mounting groove 111 and the mounting part 22), and ensure that the posture of the heat sink assembly 20 is more accurate.

[0065] See Figure 5 and Figure 6 The mounting portion 22 includes a first sub-mounting portion 221 and a second sub-mounting portion 222. The first sub-mounting portion 221 extends along a first direction, and one end of the first sub-mounting portion 221 along the first direction is connected to the radiator assembly 20. The second sub-mounting portion 222 protrudes from one side of the first sub-mounting portion 221 along a second direction, and one end of the second sub-mounting portion 222 along the first direction is connected to the radiator assembly 20. The second sub-mounting portion 222 can be received in the mounting groove 111, and the outer contour of the side of the second sub-mounting portion 222 opposite to the first sub-mounting portion 221 along the second direction mates with the mounting groove 111. Thus, by setting the first sub-mounting portion 221 to overlap the second bracket 113, it is convenient to process, position, and limit the mounting portion 22; by setting the second sub-mounting portion 222 that mates with the mounting groove 111, it is convenient to install the radiator assembly 20, thereby improving the installation accuracy and efficiency of the radiator assembly 20.

[0066] See Figure 6 and Figure 7 The suspension structure 10 also includes a suspension pad 14 and a third fastener 15. The suspension pad 14 has a limiting groove (not shown in the figure) along its circumference. The end of the suspension bracket 11 away from the radiator assembly 20 in a first direction is fitted onto the suspension pad 14 via the limiting groove. The third fastener 15 passes through the frame 30 and the suspension pad 14 in a second direction. Optionally, the suspension pad 14 is a rubber pad; the third fastener 15 is a bolt. Thus, by providing the suspension pad 14, resonance between the radiator assembly 20 and the vehicle's engine during operation is avoided, thus preventing it from affecting normal operation. The third fastener 15 connects the second bracket 113 and the frame 30, making the connection simple and reliable.

[0067] In some embodiments, two suspension pads 14 are provided, and the two suspension pads 14 are stacked along the second direction, with limiting grooves formed on the two suspension pads 14. That is, the two suspension pads 14 are provided with limiting grooves on the sides that abut against each other along the second direction, and the second bracket 113 is sleeved on the two suspension pads 14.

[0068] In some embodiments, the suspension structure 10 further includes a clamping member 16, which is pressed against the side of the suspension pad 14 away from the frame 30 along a second direction; wherein a third fastener 15 passes through the clamping member 16 along the second direction. Optionally, the clamping member 16 is a metal gasket. Thus, by providing the clamping member 16, the compression amount of the suspension pad 14 after being clamped meets the installation requirements. The installation requirements are specifically defined, but this is not the scope of this invention and will not be described in detail here.

[0069] See Figure 7In some embodiments, the suspension structure 10 further includes a limiting member 17 extending through the suspension pad 14 along a second direction, the limiting member 17 being used to limit the position of the suspension pad 14; wherein, a third fastener 15 is inserted into the limiting member 17. Thus, by providing the limiting member 17, the position of the suspension pad can be limited, preventing the suspension pad 14 from being flattened, warped, etc.

[0070] This application also provides a vehicle (not shown in the figure), including a frame 30, a radiator assembly 20 and a suspension structure 10 as described in any of the above embodiments.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
