Description

Technical Field

[0001] This utility model relates to the technical field of high-strength compressive aluminum profiles, and in particular to a high-strength compressive aluminum profile. Background Technology

[0002] In modern industry and construction, aluminum profiles have become an important choice for structural materials due to their low density, high specific strength, and corrosion resistance. With the development of equipment manufacturing towards lightweight and high reliability, and the increasing requirements for space utilization and durability in building structures, the application of high-strength compressive aluminum profiles is becoming more and more widespread, covering aerospace, rail transportation, new energy vehicles, and high-rise curtain walls. However, traditional high-strength compressive aluminum profiles still face many technical bottlenecks in practical applications. On the one hand, a single profile structure cannot simultaneously meet the requirements of high compressive strength and lightweight. Some reinforced aluminum profiles increase strength by increasing wall thickness or adding reinforcing ribs, but this leads to increased weight and cost, and stress concentration under complex loads can easily occur, causing structural failure. On the other hand, in high-temperature or high-energy-consumption scenarios (such as motor housings and photovoltaic brackets), the heat dissipation performance of aluminum profiles is insufficient. Heat accumulation not only reduces the mechanical properties of the material but may also affect the operational stability of the equipment. In addition, the buffer energy absorption design of existing aluminum profiles is relatively weak. When subjected to impact loads (such as vehicle collisions and earthquakes), it is difficult to effectively absorb energy, which can easily cause structural damage or even safety accidents.

[0003] The applicant discovered through a search that a Chinese patent discloses "A High-Strength Compressive Aluminum Profile," with publication (announcement) number "CN206668039U." This patent mainly utilizes a cross-shaped protrusion and a cross-shaped groove, with the protrusion and groove matching each other and a cylindrical groove connected to the bottom of the cross-shaped groove. The cross-shaped protrusion and groove allow for the assembly and fitting of multiple aluminum profiles to accommodate different lengths, making transportation more convenient and faster. However, this patent fails to effectively reduce damage to the aluminum profile from external impacts by incorporating a multi-layered buffer structure. In actual use, when the aluminum profile is subjected to external impacts, the lack of a multi-layered buffer structure means that the impact force acts directly on the profile body, leading to a decrease in key performance indicators such as strength and stiffness. Therefore, we propose a high-strength compressive aluminum profile. Utility Model Content

[0004] The purpose of this utility model is to provide a high-strength, pressure-resistant aluminum profile to solve the problem mentioned in the background art that it is impossible to effectively reduce the damage caused by external impact to aluminum profiles by setting up a multi-layer buffer structure. In actual use, when aluminum profiles are subjected to external impact, the lack of a multi-layer buffer structure means that the impact force will act directly on the profile body, which will lead to a decrease in the profile's key performance indicators such as strength and stiffness.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength, pressure-resistant aluminum profile, comprising an aluminum profile body, a buffer assembly provided on the top of the aluminum profile body, the buffer assembly comprising a fixing rod, a spring, a limiting block, a sliding rod, and a slider, the top of the aluminum profile body having multiple sets of through holes distributed at equal intervals, the front of the aluminum profile body having multiple sets of hollow grooves distributed at equal intervals, rubber pads being fixedly installed on the inner bottom wall of each set of hollow grooves, and the fixing rod being connected to a polyurethane sponge pad via a pressure-resistant plate.

[0006] As a preferred embodiment, the outer wall of the fixing rod is slidably connected to the inner wall of a set of through holes, the top of the fixing rod is fixedly connected to the bottom of the pressure-resistant plate, the top of the pressure-resistant plate is fixedly connected to the bottom of the polyurethane foam pad, and one end of the spring is fixedly connected to the top of the aluminum profile body.

[0007] As a preferred embodiment, the other end of the spring is fixedly connected to the bottom of the pressure-resistant plate, the spring is sleeved on the outside of the fixing rod, the limiting block is fixedly connected to the bottom of the fixing rod, and the outer wall of the limiting block is slidably connected to the inner wall of a set of hollow grooves.

[0008] As a preferred embodiment, the slide rod is fixedly installed at the bottom of the pressure-resistant plate and located to the left of the fixed rod. The slider is fixedly connected to the lower outer wall of the slide rod. A groove is provided on the inner wall of another set of hollow grooves. The slider is slidably connected to the inner wall of the groove. The outer wall of the slide rod is slidably connected to the inner wall of another set of through holes.

[0009] As a preferred embodiment, a heat dissipation component is provided on the front side of the aluminum profile body. The heat dissipation component includes copper heat-conducting rods. Multiple sets of mounting holes are opened on the outer wall of the front side of the aluminum profile body, and multiple sets of copper heat-conducting rods are provided. The multiple sets of copper heat-conducting rods are respectively fixedly installed inside the multiple sets of mounting holes.

[0010] As a preferred embodiment, multiple sets of heat dissipation fins are fixedly installed on the front outer wall of the aluminum profile body and located below the copper heat-conducting rod. Multiple sets of grooves are formed on the surface of the multiple sets of heat dissipation fins.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the set buffer components, the polyurethane foam pad directly contacts the external impact and absorbs part of the energy with its own elasticity, which is the first level of buffer. Then, the spring is compressed and deformed under pressure, converting kinetic energy into elastic potential energy, which is the second level of buffer. When the limit position is reached, the rubber pad in the hollow groove provides the final buffer to prevent rigid collision. The three-level buffer structure is progressive. Compared with the single buffer method, it can effectively reduce the damage of external impact force to the aluminum profile body. The through hole and the fixed rod and sliding rod are closely matched to provide precise guidance for the movement of the pressure plate, so that the pressure plate always maintains vertical movement during the buffering process, avoiding local stress concentration caused by displacement, so that the aluminum profile can still maintain structural stability when subjected to complex impacts.

[0013] 2. The heat dissipation components and mounting holes provide precise positioning and installation for the copper heat-conducting rods. Utilizing the excellent thermal conductivity of copper, the heat inside the aluminum profile is quickly conducted and dispersed. The heat dissipation fins effectively increase the heat dissipation area and accelerate heat conduction to the air. The grooves on the surface of the heat dissipation fins can disrupt airflow and enhance heat exchange between the air and the fins. Through the cooperation of the copper heat-conducting rods, mounting holes, heat dissipation fins, and grooves, the effect of rapid heat dissipation and uniform dispersion from the inside of the aluminum profile can be achieved.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see the appendix Figure 1 - Appendix Figure 5 A high-strength, pressure-resistant aluminum profile includes an aluminum profile body 1. A buffer assembly 2 is provided on the top of the aluminum profile body 1. The buffer assembly 2 includes a fixing rod 204, a spring 207, a limiting block 208, a sliding rod 209, and a slider 210. Multiple sets of through holes 201 are opened on the top of the aluminum profile body 1 at equal intervals. Multiple sets of hollow grooves 202 are opened on the front of the aluminum profile body 1 at equal intervals. Rubber pads 203 are fixedly installed on the inner bottom wall of each set of hollow grooves 202. A polyurethane sponge pad 206 is connected to the fixing rod 204 through a pressure-resistant plate 205.

[0023] The through hole 201 and the hollow groove 202 provide a movement trajectory for the slide bar 209 and the fixed bar 204, ensuring the stability of their movement direction. The rubber pad 203 installed in the hollow groove 202 plays a role when the limit block 208 or the slider 210 touches the bottom, further absorbing the impact energy and enhancing the buffering effect.

[0024] The outer wall of the fixing rod 204 is slidably connected to the inner wall of a set of through holes 201. The top of the fixing rod 204 is fixedly connected to the bottom of the pressure-resistant plate 205. The top of the pressure-resistant plate 205 is fixedly connected to the bottom of the polyurethane foam pad 206. One end of the spring 207 is fixedly connected to the top of the aluminum profile body 1, and the other end of the spring 207 is fixedly connected to the bottom of the pressure-resistant plate 205. The spring 207 is sleeved on the outside of the fixing rod 204. The limiting block 208 is fixedly connected to the fixing rod 204. At the bottom of rod 204, the outer wall of limiting block 208 is slidably connected to the inner wall of a set of hollow grooves 202. Sliding rod 209 is fixedly installed at the bottom of pressure plate 205 and located to the left of fixed rod 204. Sliding block 210 is fixedly connected to the lower outer wall of sliding rod 209. A sliding groove 211 is provided on the inner wall of another set of hollow grooves 202. Sliding block 210 is slidably connected to the inner wall of sliding groove 211. The outer wall of sliding rod 209 is slidably connected to the inner wall of another set of through holes 201.

[0025] The outer wall of the fixing rod 204 is slidably connected to the inside of the through hole 201, which can guide the pressure plate 205 to move vertically up and down and avoid deviation. The bottom limiting block 208 of the fixing rod 204 is embedded in the hollow groove 202, which can limit the pull-out distance of the fixing rod 204 and ensure structural stability.

[0026] Specifically, through the set buffer component 2, the polyurethane sponge pad 206 directly contacts the external impact load and absorbs part of the energy through its own elastic deformation, forming the first level of buffer. The spring 207 is compressed under pressure, converting kinetic energy into elastic potential energy, forming the second level of buffer. When the limit position is reached, the rubber pad 203 in the hollow groove 202 provides the final buffer to avoid rigid collision. The three-level buffer structure acts in sequence. Compared with the single buffer method, it can effectively reduce the damage of external impact force to the aluminum profile body 1. The through hole 201 cooperates with the fixed rod 204 and the sliding rod 209 to provide guidance for the movement of the pressure plate 205, so that it maintains vertical movement during the buffering process, avoids local stress concentration caused by displacement, and ensures that the aluminum profile maintains structural stability when subjected to complex impacts.

[0027] Please see the appendix Figure 1 - Appendix Figure 4 and appendix Figure 6 The aluminum profile body 1 has a heat dissipation component 3 on its front side. The heat dissipation component 3 includes a copper heat-conducting rod 302. Multiple sets of mounting holes 301 are provided on the outer wall of the front side of the aluminum profile body 1. Multiple sets of copper heat-conducting rods 302 are provided. The multiple sets of copper heat-conducting rods 302 are fixedly installed inside the multiple sets of mounting holes 301. Multiple sets of heat dissipation fins 303 are fixedly installed on the outer wall of the front side of the aluminum profile body 1 and are located below the copper heat-conducting rods 302. Multiple sets of grooves 304 are provided on the surface of the multiple sets of heat dissipation fins 303.

[0028] The grooves 304 are formed on the surface of the heat dissipation fin plate 303. They can disturb the air boundary layer and enhance air turbulence. When air flows through the grooves 304, it can form turbulence, break the static air layer that is close to the surface of the heat dissipation fin plate 303, and make it easier for fresh air to contact the heat dissipation fin plate 303, thus accelerating the convective heat dissipation speed.

[0029] Specifically, the heat dissipation component 3 and the mounting hole 301 provide positioning and installation for the copper heat conduction rod 302. The copper heat conduction rod 302 conducts and disperses the heat inside the aluminum profile body 1. The heat dissipation fin plate 303 increases the heat dissipation area and accelerates the heat conduction to the air. The groove 304 is located on the surface of the heat dissipation fin plate 303, which disrupts the air flow and enhances heat exchange. The copper heat conduction rod 302, the mounting hole 301, the heat dissipation fin plate 303 and the groove 304 cooperate with each other to realize the conduction and dispersion of heat from the inside of the aluminum profile body 1.

[0030] The working principle of this utility model is as follows: This utility model is a high-strength, pressure-resistant aluminum profile. First, when the top of the aluminum profile body 1 is subjected to an external impact load, the polyurethane sponge pad 206 directly contacts the impact and deforms first due to its elasticity, absorbing part of the impact energy and slowing down the transmission of the impact force. Under the continuous action of the impact force, the pressure-resistant plate 205 drives the fixed rod 204 and the sliding rod 209 to move downward along the through hole 201. The spring 207 converts kinetic energy into elastic potential energy, further absorbing the impact energy and reducing the impact speed. When the pressure-resistant plate 205 reaches its limit position, the limiting block 208 at the bottom of the fixed rod 204 or the slider 210 on the sliding rod 209 touches the rubber pad 203 in the hollow groove 202. The rubber pad 203 absorbs the residual impact energy through elastic deformation, preventing rigid collisions from damaging the aluminum profile body 1. At the same time, the sliding cooperation between the through hole 201 and the fixed rod 204 and the sliding rod 209, as well as the sliding cooperation between the slider 210 and the groove 211, are also achieved. The guiding and limiting functions of the limiting block 208 and the hollow groove 202 ensure the vertical movement of the pressure plate 205 and avoid local stress concentration caused by displacement. Secondly, when the aluminum profile body 1 generates heat during use, the heat inside the aluminum profile body 1 is transferred to the copper heat-conducting rod 302 in the mounting hole 301 through heat conduction. With its good thermal conductivity, the copper heat-conducting rod 302 quickly conducts the heat along the rod and disperses it to the front of the aluminum profile body 1. After the heat is conducted to the copper heat-conducting rod 302, the heat dissipation fin plate 303 can increase the contact area with the air and accelerate the conduction of heat from the profile surface to the air. When the air flows through the surface of the heat dissipation fin plate 303, the groove 304 disturbs the air boundary layer, causing the air to vortex and form turbulence. Under turbulent conditions, the heat exchange efficiency between the air and the surface of the heat dissipation fin plate 303 is greatly improved, and fresh air is more likely to contact the fin surface, accelerating the convective heat dissipation speed, thereby realizing the rapid conduction and dispersion of heat inside the aluminum profile body 1.
