[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present utility model and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0036] To solve the problem of the large weight of the saddle pad in the prior art and improve the manufacturing convenience and reliability of the product, the present utility model provides a lightweight saddle pad. Among them, the tractor includes a saddle pad, and the saddle pad is the saddle pad described above and below.

[0037] As Figure 1 shown, the lightweight saddle pad includes a pad body 10. A plurality of first assembly holes 11 are formed in the pad body 10. The pad body 10 is used to connect to the cross beam of the frame through the plurality of first assembly holes 11. Among them, a part of the pad body 10 bulges to form a support convex part 20, and at least a part of the support convex part 20 is in a continuously extending ring shape. The first assembly holes 11 are arranged avoiding the support convex part 20. A plurality of second assembly holes 21 are formed in the support convex part 20. The support convex part 20 is used to connect to the saddle through the plurality of second assembly holes 21.

[0038] Applying the technical solution of the present utility model, a lightweight saddle pad is provided, including a pad body 10. A plurality of first assembly holes 11 are formed in the pad body 10. The pad body 10 is used to connect to the cross beam of the frame through the plurality of first assembly holes 11. Among them, a part of the pad body 10 bulges to form a support convex part 20, and at least a part of the support convex part 20 is in a continuously extending ring shape. The first assembly holes 11 are arranged avoiding the support convex part 20. A plurality of second assembly holes 21 are formed in the support convex part 20. The support convex part 20 is used to connect to the saddle through the plurality of second assembly holes 21. In this way, by improving the overall forming structure of the saddle pad, at least a part of the support convex part 20 is in a continuously extending ring shape, which is beneficial to reducing the weight of the saddle pad. Further, since the support convex part 20 is formed by bulging a part of the pad body 10, that is, the support convex part 20 and the pad body 10 are of an integral structure, ensuring the forming convenience of the saddle pad. Since there is no need for welding connection between the support convex part 20 and the pad body 10, it is ensured that the saddle pad provided by the present application has good processability compared with the existing welding connection of multiple structures.

[0039] As Figure 1 shown, a plurality of first assembly holes 11 are formed on both sides of the pad body 10. The plurality of first assembly holes 11 on the same side are arranged at intervals in the first direction. The letter A in the figure represents the first direction. The plurality of second assembly holes 21 are arranged at intervals in the second direction perpendicular to the first direction. The letter B in the figure represents the second direction.

[0040] As Figure 1As shown, the supporting convex part 20 includes a supporting boss 22, a first extension rib 23 and a second extension rib 24. Among them, the supporting boss 22 extends continuously in a ring shape; the first extension rib 23 is connected to a part of the outer peripheral edge of the supporting boss 22 and extends in a first direction; the second extension rib 24 is connected to a part of the outer peripheral edge of the supporting boss 22 and extends in a second direction perpendicular to the first direction; among them, a part of the plurality of second assembly holes 21 are opened on the supporting boss 22, and the remaining second assembly holes 21 are opened on the second extension rib 24.

[0041] It should be noted that in the present application, as Figure 1 shown, the supporting boss 22 is a square ring structure, and the height of the supporting boss 22 relative to the backing plate body 10 is 20 mm.

[0042] Furthermore, considering the torsional conditions at the four corners of the backing plate body 10, combined with Figures 1 to 3 it can be known that at least the first extension rib 23 is connected to the corner of the supporting boss 22 in the first direction, and the first extension rib 23 extends in a shrinking shape in the direction away from the supporting boss 22; at least the second extension rib 24 is connected to the corner of the supporting boss 22 in the second direction, and the second extension rib 24 extends with the shape of the cross-section remaining unchanged in the direction away from the supporting boss 22 and penetrates through the end of the backing plate body 10; among them, the first extension rib 23 and the second extension rib 24 are smoothly transitioned and form an arc angle 100 on the side facing away from the supporting boss 22. In this way, the setting of the arc angle 100 is beneficial to dispersing and reducing the stress formed at the four corners of the backing plate body 10 due to the torsional conditions.

[0043] Specifically, Figure 2 is a schematic diagram of stress analysis at the same position of the saddle backing plate before optimization (prior art) under the condition of the same thickness. In this figure, the stress at this position is 919.91. Figure 3 is a schematic diagram of stress analysis at the same position of the saddle backing plate after optimization (the present application) under the condition of the same thickness. Due to the setting of the arc angle 100 at the same position, the stress at this position is 802.564, which is lower than the stress at the same position of the saddle backing plate before optimization (prior art).

[0044] It should be noted that in the present application, the fact that the above-mentioned first extension rib 23 extends in a shrinking shape in the direction away from the supporting boss 22 specifically means that the height of the first extension rib 23 gradually becomes shorter, and the width of the first extension rib 23 gradually becomes narrower, and both are smoothly transitioned during the process of becoming shorter and narrower.

[0045] Such as Figure 1 、 Figure 6 and Figure 7As shown, there are four first extension ribs 23, and the four first extension ribs 23 are respectively connected to the four corners of the support boss 22 in the first direction; the support protrusion 20 includes two groups of second extension rib groups, the first group of second extension rib groups includes four second extension ribs 24, and the four second extension ribs 24 in the first group are respectively connected to the four corners of the support boss 22 in the second direction; the second group of second extension rib groups includes multiple second extension ribs 24, and the multiple second extension ribs 24 in the second group are evenly distributed at the two side edges of the support boss 22 in the second direction; wherein, there is a smooth transition between two adjacent second extension ribs 24 on the same side, and an arc segment 200 is formed on the side away from the support boss 22. In this way, the provision of the arc segment 200, and the arrangement of the arc segment 200 around the first assembly hole 11, is conducive to dispersing the stress of the first assembly hole 11 and avoiding the stress concentration phenomenon at the first assembly hole 11.

[0046] Specifically, Figure 6 This is a schematic diagram of stress analysis at the same position of the saddle pad before optimization (existing technology) under the same thickness condition. In this figure, the stress magnitude at this position is 1367.78. Figure 7 It is a schematic diagram of stress analysis at the same position of the saddle pad after optimization (this application) under the same thickness conditions. In this figure, since an arc segment 200 is set at the same position, the stress magnitude at this position is 673.655, which is lower than the stress magnitude at the same position of the saddle pad before optimization (prior art).

[0047] like Figure 1 , Figure 4 and Figure 5 As shown, at least a portion of the support boss 22 extending along the second direction is provided with a first weight-reducing hole 221, and the support protrusion 20 also has an energy-absorbing rib 25; wherein the energy-absorbing rib 25 is located between the first weight-reducing hole 221 and the second assembly hole 21; and / or, the energy-absorbing rib 25 is located between two adjacent second assembly holes 21. In this way, the provision of the energy-absorbing rib 25 is conducive to transferring the stress at the second assembly hole 21 to the energy-absorbing rib 25, or transferring the stress at the first weight-reducing hole 221 to the energy-absorbing rib 25.

[0048] Specifically, Figure 4 This is a schematic diagram of stress analysis at the same position of the saddle pad before optimization (existing technology) under the same thickness condition. In this figure, the stress magnitude at this position is 1205.398. Figure 5 It is a schematic diagram of stress analysis at the same position of the saddle pad after optimization (this application) under the same thickness conditions. In this figure, since energy-absorbing ribs 25 are set at the same position, the stress magnitude at this position is 926.927, which is lower than the stress magnitude at the same position of the saddle pad before optimization (prior art).

[0049] like Figure 1 As shown, the energy absorbing ribs 25 extend along the first direction and penetrate the inner and outer edges of the supporting bosses 22. In this way, the energy absorbing ribs 25 are guaranteed to disperse and absorb stress reliably.

[0050] It should be noted that, in the present application, the energy absorbing rib 25 is formed by partially recessing the supporting boss 22 , and the recess depth of the energy absorbing rib 25 is smaller than the raised height of the supporting boss 22 .

[0051] Optionally, the depression depth of the energy absorbing rib 25 ranges from 3 to 7 mm.

[0052] Preferably, the recessed depth of the energy absorbing rib 25 is 5 mm.

[0053] Optionally, the height of the protrusion of the support boss 22 ranges from 20 to 50 mm.

[0054] Preferably, the protrusion height of the supporting boss 22 is 20 mm.

[0055] like Figure 1 As shown, the support protrusion 20 further includes a plurality of reinforcing ribs 26, which are evenly distributed at the outer edges of both sides of the support boss 22 in the first direction, and the reinforcing ribs 26 are staggered with the energy absorbing ribs 25. In this way, the arrangement of the plurality of reinforcing ribs 26 ensures that the saddle pad has sufficient structural strength.

[0056] like Figure 1 As shown, the edge of the first lightening hole 221 is bent toward one side of the pad body 10 to form an annular flange 2211. In this way, the setting of the annular flange 2211 is conducive to strengthening the periphery of the first lightening hole 221 and further reducing the stress at the first lightening hole 221.

[0057] It should be noted that, in the present application, the first weight-reducing hole 221 is a waist-shaped hole.

[0058] Optionally, in the bending direction of the hole edge of the first weight-reducing hole 221 , the bending width of the annular flange 2211 is in the range of 5 to 7 mm.

[0059] Preferably, the bending width of the annular flange 2211 is 6 mm.

[0060] Optionally, the bending angle of the hole edge of the first weight-reducing hole 221 ranges from 30° to 60°.

[0061] Preferably, the bending angle of the hole edge of the first weight-reducing hole 221 is 45°.

[0062] It should be noted that in the present application, the thickness of the pad body 10 at the hole edge of the first assembly hole 11 is greater than the thickness at the remaining positions of the pad body 10; and / or, the thickness of the support protrusion 20 at the hole edge of the second assembly hole 21 is greater than the thickness at the remaining positions of the support protrusion 20. In this way, stress concentration at the first assembly hole 11 is avoided, and stress concentration at the second assembly hole 21 is avoided.

[0063] Optionally, both the hole edge of the first assembly hole 11 and the hole edge of the second assembly hole 21 are locally thickened, and the thickening is integrally formed. Of course, patches can also be attached to the hole edge of the first assembly hole 11 and the hole edge of the second assembly hole 21.

[0064] Optionally, a rib structure is provided at the hole edge of the first assembly hole 11 and the hole edge of the second assembly hole 21. For example, it can be a nut seat or a rib.

[0065] Optionally, the stress concentration regions at the hole edge of the first assembly hole 11 and the hole edge of the second assembly hole 21 are both subjected to laser strengthening treatment to improve the surface strength of the stress concentration regions.

[0066] As Figure 1 shown, a second weight reduction hole 12 is provided in the middle of the pad body 10, and the support protrusion 20 is located on the outer peripheral side of the second weight reduction hole 12. In this way, it is beneficial to the overall lightweight design of the saddle pad.

[0067] As Figure 1 shown, the pad body 10 has weight reduction notches 13 at both side edges in the first direction. In this way, it is beneficial to the overall lightweight design of the saddle pad.

[0068] It should be noted that in the present application, the thickness range of the pad body 10 is 1 - 10 mm; and / or, the thickness range of the support protrusion 20 is 1 - 10 mm. In this way, the weight reduction ratio of the saddle pad provided in the present application is 30% - 50% (specifically, refer to Table 1).

[0069] Furthermore, the thickness range of the pad body 10 is 3 - 6 mm; and / or, the thickness range of the support protrusion 20 is 3 - 6 mm.

[0070] Preferably, the thickness of the pad body 10 is 5 mm; the thickness of the support protrusion 20 is 5 mm. In this way, compared with the existing saddle pad with a thickness of 8 mm, the weight reduction ratio exceeds 20%.

[0071] Table 1 Comparison of the weights of the saddle pad with a thickness of 8 mm and the saddle pad with a thickness of 5 mm

[0072] Original weight Current weight of 5mm Weight reduction Percentage of weight reduction 29.7 19.7 10 33.67% 37.5 21.8 15.7 41.87% 33.5 22 11.5 34.33%

[0073] Applying the technical solution of the present utility model, a lightweight saddle pad is provided, which includes a pad body 10. A plurality of first assembly holes 11 are formed at both ends of the pad body 10. The plurality of first assembly holes 11 at the same end are arranged at intervals in a first direction. The pad body 10 is used to be connected to the cross beam of the vehicle frame through the plurality of first assembly holes 11. Among them, a part of the pad body 10 bulges to form a supporting convex part 20, and at least a part of the supporting convex part 20 is in a continuously extending ring shape. The first assembly holes 11 are arranged avoiding the supporting convex part 20. A plurality of second assembly holes 21 are formed on the supporting convex part 20. The plurality of second assembly holes 21 are arranged at intervals in a second direction perpendicular to the first direction. The supporting convex part 20 is used to be connected to the saddle through the plurality of second assembly holes 21. In this way, since the supporting convex part 20 is formed by the bulge of a part of the pad body 10, that is, the supporting convex part 20 and the pad body 10 are of an integral structure, the forming convenience of the saddle pad is ensured. Since there is no need for welding connection between the supporting convex part 20 and the pad body 10, it is ensured that the saddle pad provided by the present application has good processability compared with the existing multi-piece structure welded connection.
