Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a vehicle underbody protection plate and vehicle. Background Technology

[0002] Underbody protection plates are used to protect the engine from impacts and damage caused by uneven road surfaces, stones, and other external objects during vehicle operation, thus ensuring the engine's normal operation. Therefore, the underbody protection plates themselves must possess sufficient strength to meet the requirements of various complex operating conditions in real-world use.

[0003] The underbody protection plates in related technologies are insufficient in terms of strength. When a vehicle is driving through water, the underbody protection plates, due to their insufficient strength, are prone to breakage when subjected to the impact of water flow or collisions with potential underwater obstacles. Once the underbody protection plate breaks, it can no longer perform its due protective function, leaving important components such as the engine directly exposed to a dangerous environment, increasing the risk of engine damage, and consequently affecting the overall performance of the vehicle and driving safety. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] The underbody protection plates in related technologies are insufficient in terms of strength. When a vehicle is driving through water, the underbody protection plates, due to their insufficient strength, are prone to breakage when subjected to the impact of water flow or collisions with potential underwater obstacles. Once the underbody protection plate breaks, it can no longer perform its due protective function, leaving important components such as the engine directly exposed to a dangerous environment, increasing the risk of engine damage, and consequently affecting the overall performance of the vehicle and driving safety.

[0041] The following is for reference. Figures 1-10 Description of the bottom protective plate 1 according to an embodiment of the present utility model.

[0042] like Figures 1-3 As shown, the underbody protection plate 1 according to this utility model is used in vehicles. The underbody protection plate 1 includes an underbody protection plate body 11. The underbody protection plate body 11 is formed with a first body portion 111 and a second body portion 112. The second body portion 112 is connected to the first body portion 111 and its width gradually decreases in the direction away from the first body portion 111, so that the underbody protection plate body 11 can adapt to the shape and installation requirements of different areas of the vehicle bottom, ensuring good installation adaptability.

[0043] The first body portion 111 has a first reinforcing protrusion 1111 protruding on its surface. The first reinforcing protrusion 1111 is configured as a plurality of protrusions extending in the length direction and spaced apart in the width direction. By extending in the length direction, the first reinforcing protrusion 1111 enhances the structural strength of the first body portion 111 in the longitudinal direction (vehicle longitudinal direction), allowing it to better disperse stress and reduce the possibility of deformation and damage when subjected to longitudinal impact forces (such as the impact of a vehicle encountering a raised road surface). The spaced-apart arrangement in the width direction provides reinforcement at different locations, improving overall impact resistance while allowing for reasonable control of material usage.

[0044] The second body portion 112 has a second reinforcing protrusion 1121 protruding from its surface. The second reinforcing protrusion 1121 is configured as a plurality of protrusions extending in the length direction and spaced apart in the width direction. The second reinforcing protrusion 1121 can enhance the structural stability of the second body portion 112 in the longitudinal and lateral (left-right direction of the vehicle) directions, taking into account the geometric feature of the gradually decreasing width of the second body portion 112. This ensures that even if the second body portion 112 is subjected to forces in different directions during vehicle operation, it can maintain good integrity and continuously provide reliable protection for components such as the engine.

[0045] Therefore, according to the bottom guard plate 1 of this utility model, by specifically setting the first reinforcing protrusion 1111 and the second reinforcing protrusion 1121 according to the geometric features of the first body part 111 and the second body part 112, the overall strength and impact resistance of the bottom guard plate 1 are effectively improved, and the protection requirements can be better met.

[0046] According to some embodiments of this utility model, such as Figure 2 As shown, at least one of the first reinforcing protrusion 1111 and the second reinforcing protrusion 1121 has a first edge 1112 and a second edge 1113. The first edge 1112 extends in the length direction, which can further enhance the bending resistance of the bottom guard plate 1 in the longitudinal direction, making it less likely to break when facing water flow impact or obstacle collision. The second edge 1113 extends in the width direction, which helps to improve the rigidity of the bottom guard plate 1 in the lateral direction and suppress local deformation caused by lateral force.

[0047] The first edge 1112 and the second edge 1113 are connected by an arc-shaped transition section 1114, which optimizes stress distribution and allows stress to be transmitted and dispersed more smoothly between the first edge 1112 and the second edge 1113. When subjected to external force, the arc-shaped transition section 1114 can guide the stress to gradually change along the arc, avoiding excessive stress concentration at a certain point, thereby reducing the possibility of damage to the reinforcing protrusion at the edge and enhancing the structural strength and impact resistance of the bottom guard plate 1.

[0048] According to some embodiments of this utility model, such as Figure 2 As shown, in at least one of the first reinforcing protrusion 1111 and the second reinforcing protrusion 1121, the first edge 1112 is constructed as two parallel edges spaced apart in the width direction. Therefore, in the width direction, there are two parallel edge segments that are spaced apart from each other by a certain distance, which can increase the force distribution range of the reinforcing protrusion in the width direction.

[0049] The second edge 1113 is constructed as two parallel edges spaced apart along the length direction. That is, the reinforcing protrusion has two parallel edge segments spaced apart along the length direction, which can enhance the structural stability of the reinforcing protrusion in the longitudinal direction and make the stress more evenly distributed along the length direction of the reinforcing protrusion, thereby improving the load-bearing capacity of the reinforcing protrusion in the longitudinal direction.

[0050] The two first edges 1112 are connected to the two second edges 1113 via arc-shaped transition sections 1114, enabling a smooth transition of stress between the first edges 1112 and the second edges 1113. When the reinforcing protrusion is subjected to external force, the arc-shaped transition section 1114 can guide the stress to gradually change along the arc curve, avoiding abrupt changes and concentrations of stress at the connection point. This improves the overall strength and fatigue resistance of the reinforcing protrusion, allowing it to better withstand and disperse stress in all directions, providing more reliable support and protection for the bottom guard plate 1.

[0051] It should be noted that, in the specific embodiments of this utility model, the reinforcing protrusion can represent the first reinforcing protrusion 1111, the second reinforcing protrusion 1121, or both the first reinforcing protrusion 1111 and the second reinforcing protrusion 1121.

[0052] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the number of the first reinforcing protrusions 1111 is n1, and the number of the second reinforcing protrusions 1121 is n2, satisfying that n1≥n2. Since the second body part 112 has a tapered geometric feature compared to the first body part 111, appropriately reducing the number of the second reinforcing protrusions 1121 (n2) can also ensure the necessary structural strength, achieving a balance between the protective performance and lightweight requirements of the bottom guard plate 1.

[0053] n1≥n2 can significantly improve the protective capability of the first body part 111 without excessively increasing the structural complexity of the second body part 112, so that the reinforcing protrusions in different areas can maintain a reasonable spacing, which is convenient for stamping and quality control.

[0054] According to some embodiments of this utility model, such as Figure 4 As shown, the second body portion 112 has a through-hole 1122 for weight reduction. The shape of the weight reduction hole 1122 can be designed as circular, elliptical, square, polygonal, etc., according to actual needs. By opening the weight reduction hole 1122 in the second body portion 112, the amount of material used in this part is directly reduced, thereby achieving the purpose of weight reduction. Moreover, the weight reduction hole 1122 is a hole that penetrates the thickness of the second body portion 112, making the weight reduction effect more significant.

[0055] The weight-reducing holes 1122 are arranged in multiple spaced intervals, which can ensure the weight-reduction effect while avoiding excessively low local strength of the second body part 112 due to concentrated openings. The spacing can be reasonably determined according to factors such as the size of the second body part 112, the stress conditions, and design requirements.

[0056] Each weight-reducing hole 1122 has a flange 1123 protruding from the surface of the second body portion 112 at its edge. The flange 1123 is formed by folding the material at the edge of the weight-reducing hole 1122. The flange 1123 protrudes from the surface of the second body portion 112, increasing the material thickness and structural strength at the edge of the weight-reducing hole 1122. The flange 1123 can effectively improve the local strength around the weight-reducing hole 1122. When the second body portion 112 is subjected to external force, the flange 1123 can disperse the stress, preventing stress concentration at the edge of the weight-reducing hole 1122, thereby preventing the second body portion 112 from cracking or deforming at the weight-reducing hole 1122.

[0057] According to some embodiments of this utility model, such as Figure 2 As shown, the bottom protective plate body 11 has through drainage holes 113. The drainage holes 113 are multiple and are respectively located in the first body part 111 and the second body part 112, which can ensure that water in all parts of the bottom protective plate 1 can be effectively discharged, and can more comprehensively meet various drainage needs.

[0058] The drain holes 113 are elliptical in shape and are arranged in multiple groups spaced apart along the length direction. Each group of drain holes 113 includes multiple drain holes 113 spaced apart along the width direction. Compared to other hole shapes, elliptical holes provide sufficient drainage area while causing less damage to the bottom protective plate 1 structure. The multiple groups of drain holes 113 spaced apart along the length direction can cover the drainage needs of a relatively long area of ​​the bottom protective plate 1; while the multiple drain holes 113 spaced apart along the width direction within each group increases the number of drainage channels in the same area, allowing water to drain from different locations more quickly.

[0059] The drainage holes 113 in adjacent groups are staggered along the length. This staggered arrangement guides water to flow more evenly under the underbody protection plate 1, ensuring each hole 113 effectively drains water and improves overall drainage performance. Furthermore, the rational grouping, arrangement, and staggered layout do not significantly reduce the overall strength and rigidity of the underbody protection plate 1 due to the drainage holes 113, thus ensuring reliable protection for the vehicle while fulfilling its drainage function.

[0060] At least one set of drainage holes 113 has its major axis aligned with the length direction of the underbody 11, and at least another set has its major axis aligned with the width direction of the underbody 11. When the vehicle is in motion, the flow direction of water in the underbody 1 is complex and varied, flowing both along the length and width of the vehicle. Drainage holes 113 with their major axes aligned with the length direction of the underbody 11 can better adapt to the water flow in the width direction, making it easier for water to drain through the drainage holes 113; while drainage holes 113 with their major axes aligned with the width direction of the underbody 11 help handle the distribution and drainage of water in the length direction. Furthermore, from the perspective of the structural performance of the underbody 1, the staggered distribution of elliptical drainage holes 113 in different directions can effectively avoid the problem of localized weakness caused by openings in a single direction, ensuring that the underbody 1 maintains balanced mechanical performance in all directions.

[0061] According to some embodiments of this utility model, such as Figure 3As shown, the first body part 111 has an upper edge 1115 and a straight side edge 1116 connected to each other, and the second body part 112 has a lower edge 1124 and an arcuate side edge 1125 connected to each other; wherein the upper edge 1115 and the lower edge 1124 both extend in the width direction and are spaced apart in the length direction, and the straight side edge 1116 and the arcuate side edge 1125 are connected to each other and both extend in the length direction, so that the first body part 111 and the second body part 112 can form a complete bottom guard plate 1 structure, which together provides protection for important components at the bottom of the vehicle.

[0062] The first body portion 111 has a plurality of first mounting bosses 1117 and a plurality of second mounting bosses 1118. The plurality of first mounting bosses 1117 are spaced apart along the upper edge 1115, ensuring that the first body portion 111 can be firmly connected to the vehicle's underbody structure in the width direction through multiple mounting points, distributing installation stress and improving the stability and reliability of the connection. Simultaneously, the spaced arrangement of the plurality of first mounting bosses 1117 also helps to reduce the weight of the underbody protection plate 1 while ensuring installation strength.

[0063] Multiple second mounting bosses 1118 are spaced apart along the straight side edge 1116. The arrangement of multiple second mounting bosses 1118 along the straight side edge 1116 can enhance the connection strength of the first body part 111 in the length direction.

[0064] The second body portion 112 has a plurality of third mounting bosses 1126, which are spaced apart along the lower edge 1124 to ensure that the second body portion 112 is stably connected to the bottom of the vehicle in the width direction and cooperates with the mounting bosses of the first body portion 111 to improve the overall structural stability of the underbody 1.

[0065] The first mounting boss 1117, the second mounting boss 1118, and the third mounting boss 1126 each have through mounting holes. By installing fasteners in the mounting holes, the underbody protection plate 1 can be firmly fixed to the bottom of the vehicle, providing continuous and reliable protection for the vehicle's underbody components.

[0066] According to some embodiments of this utility model, such as Figure 3 , Figures 5-10 As shown, the surface of the bottom protective plate body 11 is formed with reinforcing ribs, which can enhance the structural strength and rigidity of the bottom protective plate body 11. The reinforcing ribs include transverse ribs 1141, longitudinal ribs 1142 and circumferential ribs 1143, each of which has a unique layout and function.

[0067] The transverse ribs 1141 extend along the width direction of the bottom protective plate body 11. Multiple transverse ribs 1141 are spaced apart along the length direction, which allows for effective reinforcement while controlling material usage, achieving a lightweight design. The multiple transverse ribs 1141 form multiple supports along the width direction, enhancing the bending resistance of the bottom protective plate 1 in that direction. At least one transverse rib 1141 connects two adjacent first mounting bosses 1117, better distributing the force on the first mounting bosses 1117 and improving their strength and stability.

[0068] Longitudinal ribs 1142 extend along the length of the bottom protective plate body 11, and are configured as multiple ribs spaced apart in the width direction. These multiple longitudinal ribs 1142 provide multiple supports for the bottom protective plate 1 in the length direction, enhancing its resistance to bending and torsion. At least one longitudinal rib 1142 connects two adjacent second mounting bosses 1118, thereby connecting the adjacent second mounting bosses 1118, enhancing the structural strength of the second mounting bosses 1118, distributing stress, and improving the connection stability and deformation resistance of the bottom protective plate 1 in the length direction.

[0069] The circumferential ribs 1143 are configured as a plurality of ribs spaced circumferentially around at least one third mounting boss 1126, reinforcing the bottom guard plate 1 around the third mounting boss 1126. Each circumferential rib 1143 extends from the sidewall of the third mounting boss 1126 to the surface of the bottom guard plate body 11, effectively transferring the force on the third mounting boss 1126 to the bottom guard plate body 11, increasing the stress-bearing area and reducing the degree of local stress concentration. At the same time, the circumferential ribs 1143 also enhance the connection strength between the third mounting boss 1126 and the bottom guard plate body 11, further improving the overall structural reliability of the bottom guard plate 1.

[0070] The transverse ribs 1141, longitudinal ribs 1142, and circumferential ribs 1143 work together to give the bottom guard plate 1 high strength and rigidity in all directions, which can better adapt to various complex stress conditions during vehicle operation.

[0071] According to some embodiments of this utility model, such as Figures 8-10 As shown, the second body portion 112 has a circular thickened region 1127. Compared with other parts of the second body portion 112, the thickened region 1127 has increased thickness, which can enhance the structural strength and improve the local load-bearing capacity.

[0072] The diameter of the thickened area 1127 is larger than the outer diameter of the third mounting boss 1126. The third mounting boss 1126 is disposed on the thickened area 1127, so that the third mounting boss 1126 can be stably placed on the thickened area 1127, ensuring the stability and reliability of the installation, and also providing better support for the third mounting boss 1126.

[0073] The thickness of the thickened region 1127 is h1, and the thickness of the second body 112 is h2, satisfying the condition: 1.2 ≤ h1 / h2 ≤ 1.5. This ensures that the thickened region 1127 can fulfill its intended function, such as enhancing local strength, without causing material waste, excessive weight increase, or affecting the overall structural balance of the product due to excessive thickening. By reasonably controlling h1 / h2, effective material utilization and lightweight design of the product can be achieved while meeting product performance requirements.
