Description

Technical Field

[0001] The utility model is applied to the field of automobile chassis protection, and particularly relates to an anti-scratch structure for a lower thrust rod seat. Background Art

[0002] In the field of vehicle manufacturing and design, the lower thrust rod seat is a key component in the vehicle suspension system. It is a key structure connecting the lower thrust rod of the axle to the frame, playing the role of transmitting traction and braking force, while also improving the stability and handling of the vehicle. However, in actual application, most urban buses are generally designed with a low-floor structure to increase passenger capacity and ease of boarding and alighting. For models with higher load requirements, a large-drop steering car is often used as the front axle. Then, a lower thrust rod is designed in front of the large-drop steering car. The lower thrust rod is connected to the frame through the lower thrust rod seat, and the lower thrust rod seat and the frame are connected together by welding.

[0003] However, traditional lower thrust rod mount designs often lack effective protection against scratches. Once a lower thrust rod mount is scratched, the protective layer on its surface is quickly damaged, exposing the metal material underneath. Lower thrust rod mounts are particularly vulnerable to complex and changing road conditions, where contaminants such as mud, water, and dust quickly adhere to the exposed metal surface, accelerating corrosion. Over time, this corrosion can cause the lower thrust rod mount to lose its original strength and toughness, leading to malfunction or failure during vehicle operation.

[0004] Furthermore, damage to the lower thrust rod mount not only affects the proper functioning of the suspension system but can also negatively impact the vehicle's handling and ride quality. For example, a damaged lower thrust rod mount can cause an imbalance in the vehicle's suspension system, leading to abnormal tire wear and jerking during driving. These issues can not only reduce the vehicle's ride quality but also potentially compromise its safety.

[0005] Therefore, based on the above problems, if a lower thrust rod seat anti-scratch structure can be designed, which has the advantages of simple structure, easy maintenance and low replacement cost, by installing an anti-scratch structure on the bottom of the lower thrust rod seat, the lower thrust rod seat can be prevented from directly scratching the ground under harsh road conditions, and the problem of premature rust of the lower thrust rod seat due to paint peeling off due to scratching can be effectively avoided, thereby improving the reliability and safety of the lower thrust rod seat, which can well solve the above problems. Summary of the Invention

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and design an anti-scratch structure for a lower thrust rod seat.

It can be seen that the anti-scratch structure plays a protective role for the lower thrust rod seat, and the anti-scratch guard plate plays a supporting and limiting role for the several long anti-scratch ribs and the several short anti-scratch ribs, and the several long anti-scratch ribs and the several short anti-scratch ribs all play a role in direct impact contact with the ground, avoiding direct scratching between the lower thrust rod seat and the ground. The replacement cycle of the anti-scratch structure can be judged by regularly observing the wear of the long anti-scratch ribs and the short anti-scratch ribs.

[0008] Furthermore, both ends of the anti-scratch long rib plate and the anti-scratch short rib plate are beveled, and the lowest ends of the anti-scratch long rib plate and the anti-scratch short rib plate are in contact with the ground.

[0025] like Figures 1 to 5As shown, in this embodiment, the utility model is fixedly fitted at the bottom of the lower thrust rod seat 2, and the anti-scratch structure includes an anti-scratch guard plate 10, a plurality of anti-scratch long ribs 11 and a plurality of anti-scratch short ribs 12, and the plurality of said anti-scratch long ribs 11 and the plurality of said anti-scratch short ribs 12 are all fixedly fitted on the anti-scratch guard plate 10. It can be seen that the anti-scratch structure 1 plays a protective role for the lower thrust rod seat 2, and the anti-scratch guard plate 10 plays a supporting and limiting role for the plurality of said anti-scratch long ribs 11 and the plurality of said anti-scratch short ribs 12. The plurality of said anti-scratch long ribs 11 and the plurality of said anti-scratch short ribs 12 all play a role in direct impact contact with the ground, thereby preventing the lower thrust rod seat 2 from directly scratching the ground. The replacement cycle of the anti-scratch structure 1 can be judged by regularly observing the wear of the anti-scratch long ribs 11 and the anti-scratch short ribs 12.

[0026] like Figures 7 and 8 As shown, in this embodiment, both ends of the long anti-scratch ribs 11 and the short anti-scratch ribs 12 are beveled, and their lowest ends are in contact with the ground. This shows that the beveled design of both ends of the long anti-scratch ribs 11 and the short anti-scratch ribs 12 allows them to effectively guide and disperse the impact force across the entire short rib when they directly collide with the ground, preventing localized cracking.

[0027] like Figure 6 As shown, in this embodiment, the anti-scratch guard plate 10 is provided with a plurality of mounting holes 100 and a plurality of mounting sinks 101, and the bolts are threadedly engaged with the lower thrust rod seat 2 through the mounting holes 100 and the mounting sinks 101. It can be seen that the anti-scratch guard plate 10 supports and fixes the plurality of mounting holes 100 and the plurality of mounting sinks 101, the mounting holes fix the bolts, and the mounting sinks 101 sink and protect the bolts, preventing the bolt heads from being worn when the plurality of anti-scratch long ribs 11 and the plurality of anti-scratch short ribs 12 are severely worn, thereby preventing the bolts from being properly disassembled and assembled with the anti-scratch structure 1. During the life cycle of the vehicle, maintenance personnel can replace the anti-scratch structure multiple times according to usage.

[0028] like Figure 6As shown, in this embodiment, the anti-scratch guard plate 10 is provided with a plurality of long rib grooves 102 and a plurality of short rib grooves 103. The anti-scratch long rib 11 is limitedly engaged with the anti-scratch guard plate 10 through the long rib grooves 102, and the anti-scratch short rib 12 is limitedly engaged with the anti-scratch guard plate 10 through the short rib grooves 103. Thus, it can be seen that the anti-scratch guard plate 10 supports and fixes the plurality of long rib grooves 102 and the plurality of short rib grooves 103. The plurality of long rib grooves 102 and the plurality of short rib grooves 103 respectively limit the long anti-scratch rib 11 and the plurality of short anti-scratch rib 12, so that the long anti-scratch rib 11 and the plurality of short anti-scratch rib 12 are fixed to the anti-scratch guard plate 10.

[0029] like Figures 3 to 5 As shown, in this embodiment, several of the anti-scratch long ribs 11 and several of the anti-scratch short ribs 12 are respectively engaged with the anti-scratch guard plate 10 by mortise and tenon joints, and the long anti-scratch ribs 11 and the short anti-scratch ribs 12 are connected and engaged with the anti-scratch guard plate 10 by welding. Thus, it can be seen that the several long anti-scratch ribs 11 and the several short anti-scratch ribs 12 are respectively engaged with the anti-scratch guard plate 10 by mortise and tenon joints, and the mortise and tenon joint structure greatly improves the front-to-back longitudinal structural strength of the anti-scratch structure 1. Further reinforcement through welding on the basis of the mortise and tenon joints greatly improves the front-to-back longitudinal structural strength of the anti-scratch structure 1, and the anti-scratch structure 1 is less likely to suffer structural damage when it scrapes against the ground.

[0030] like Figures 3 to 8 As shown, in this embodiment, the anti-scratch guard plate 10, the long anti-scratch rib plate 11, and the short anti-scratch rib plate 12 are all sheet metal parts. Thus, the anti-scratch guard plate 10, the long anti-scratch rib plate 11, and the short anti-scratch rib plate 12 are all sheet metal parts. They have high strength and are widely applicable. They are easy to cut and form, allowing them to be processed and deformed into various shapes as needed. Furthermore, the material cost is low, which can reduce the material cost of the anti-scratch structure 1.

[0031] like Figure 7As shown, in this embodiment, the anti-scratch long rib plate 11 includes a long rib plate back plate 110 and a pair of long rib plate tenons 111. The long rib plate back plate 110 is fixedly fitted at one end of the anti-scratch long rib plate 11 in contact with the ground. The long rib plate back plate 110 is in contact with the ground. A pair of the long rib plate tenons 111 are respectively fixed at the left and right ends of the anti-scratch long rib plate 11. A pair of the long rib plate tenons 111 are respectively fitted with mortise and tenon joints of several of the long rib plate grooves 102. A long rib plate hook 112 is provided on the long rib plate tenon 111, and the long rib plate hook 112 is connected and fitted with the bottom surface of the lower thrust rod seat 2. The rib plate hooks 112 are used to connect the lower thrust rod seat 2 and at the same time, the rib plate hooks 112 increase the longitudinal impact resistance of the anti-scratch structure 1 and reduce the shear force generated on the bolt when the anti-scratch structure 1 scrapes against the ground.

[0032] like Figure 8 As shown, in this embodiment, the anti-scratch short rib plate 12 includes a short rib plate back plate 120 and a pair of short rib plate tenons 121. The short rib plate back plate 120 is fixedly fitted at one end of the anti-scratch short rib plate 12 in contact with the ground. The short rib plate back plate 120 is in contact with the ground. The short rib plate tenons 121 are fixedly fitted at both ends of the anti-scratch short rib plate 12. A pair of the short rib plate tenons 121 are respectively fitted with the mortise and tenon joints of several of the short rib plate grooves 103. It can be seen that the anti-scratch short rib plate 12 supports and fixes the short rib plate back plate 120 and the pair of short rib plate tenons 121. The short rib plate back plate 120 contacts and collides with the ground, so that the parts of the lower thrust rod seat 2 that are prone to scratches are protected. The wear of the short rib plate back plate 120 can be checked regularly to confirm the severity of the vehicle's driving conditions, and the driver's driving habits can be adjusted in time to judge the remaining service life of the anti-scratch structure 1. The pair of short rib plate tenons 121 disperse the impact force of the collision of the short rib plate back plate 120 to avoid local bumps and cracks.

[0033] like Figure 7As shown, in this embodiment, the pair of long rib tenons 111 and the long rib hooks 112 are integrally formed on the long rib back plate 110. Thus, the pair of long rib tenons 111 and the long rib hooks 112 are integrally formed on the long rib back plate 110, which can improve the structural firmness of the anti-scratch long rib 11 and further enable its structure to withstand greater stress and pressure. The integral molding also has the characteristics of high production efficiency and high material utilization, further reducing the production cost of the anti-scratch long rib 11.

[0034] like Figure 8 As shown, in this embodiment, a pair of short rib tenons 121 are integrally formed on the short rib back plate 120. Thus, the integral formation of the pair of short rib tenons 121 on the short rib back plate 120 can improve the structural robustness of the anti-scratch short rib 12, further enabling the structure to withstand greater stress and pressure. The integral formation also has the advantages of high production efficiency and high material utilization, further reducing the production cost of the anti-scratch short rib 12.

[0035] In this embodiment, the working principle of the utility model is as follows:

[0036] like Figures 1 to 8 As shown, when a vehicle passes over a poor road surface, the lower thrust rod base 2 is prone to scraping against the ground. The anti-scratch structure 1 protects the lower thrust rod base 2 from direct scraping against the ground, which would cause the anti-rust paint on its surface to fall off. Due to the harsh environment in which the lower thrust rod base is located, muddy water and dust on the road surface can accelerate the rust process, ultimately causing premature failure during the vehicle's life cycle.

[0037] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
