Description

Technical Field

[0001] The invention belongs to the technical field of vehicle canopy systems, and in particular relates to a steel-aluminum composite guide rail structure applied to vehicle canopy systems. Background Art

[0002] The canopy system is an environmental protection facility for vehicles (usually construction vehicles such as muck trucks). When the vehicle is driving, if the muck in the truck bed is not covered, the muck in the truck bed will fly up and float / fall everywhere under the action of airflow, causing environmental pollution and increasing dust in the construction area and driving route. In order to solve the above pollution problem, the prior art adopts the method of setting a tarpaulin or a canopy system on the vehicle compartment to close the compartment to prevent the muck from flying under the airflow. The canopy system has the characteristics of electric telephone operation to reduce the burden of manpower and has been more and more widely used.

[0003] The canopy system generally includes a support system that can be slid to expand and fold and a drive system that drives the support system to expand / fold. A tarpaulin is installed on the support system. When the support system is fully expanded, the tarpaulin closes the top of the vehicle compartment. When the support system is fully folded, the tarpaulin is folded and stored, and the top of the compartment opens. Among them, the support system is composed of components such as guide rails, rollers and brackets. Under the drive of the drive system, the moving assembly composed of multiple rollers and brackets moves horizontally along the guide rails. Usually, the tarpaulin is located at the front of the truck bed after being folded. When the tarpaulin is expanded, it is gradually pulled and expanded from the front to the rear of the truck bed. It can be seen that the guide rails installed on the side of the vehicle are important components of the canopy system and play a very critical role in the working characteristics of the canopy system.

[0004] The existing guide rails are usually steel guide rails (similar in shape to rails). When installing them on the truck bed or converting the truck bed into a canopy, the bottom of the rails is welded to the side of the truck. The guide rails of the above structure have the following problems: First, the weight of the overall steel guide rail is relatively large, which leads to a large weight of the canopy system. When it is installed on the vehicle, it increases the burden on the vehicle and increases fuel consumption; second, the aforementioned steel guide rails only contact the rollers at a single position, so after the guide rails are worn out after long-term use, they need to be disassembled and replaced. The removed guide rails can only be used as waste and no longer have utilization value, resulting in a waste of materials; third, the aforementioned steel guide rails usually need to be disassembled and replaced as a whole when partial deformation, damage, wear and other problems occur, and cannot be replaced in sections; third, since the aforementioned guide rails are an integral structure, they can only be cut off from the side of the truck as a whole during replacement and maintenance, which causes damage to the side of the vehicle.

[0005] Therefore, it is necessary to develop and design a new guide rail structure to solve the above-mentioned technical problems. Summary of the invention

[0006] In order to solve the technical problems existing in the known technology, the present invention provides a steel-aluminum composite guide rail structure for a vehicle canopy system, which is lightweight, high in strength, easy to assemble and disassemble, can be assembled and disassembled in sections, is easy to repair, and has a high utilization rate.

[0007] The technical solution adopted by the present invention to solve the technical problems existing in the known technology is: a steel-aluminum composite guide rail structure applied to a vehicle canopy system includes a guide rail aluminum profile, a reinforcing steel plate and a mounting bracket; the guide rail aluminum profile includes a profile body made of aluminum alloy, a circular arc-shaped upper rail surface is provided on the top of the profile body, and a circular arc-shaped lower rail surface is provided on the bottom, a front groove is provided in the middle of the front part of the profile body, and a rear groove is provided in the middle of the rear part, a front reinforcing steel plate is provided in the front groove, and a rear reinforcing steel plate is provided in the rear groove; the mounting bracket is located behind the rear reinforcing steel plate, and the front reinforcing steel plate, the guide rail aluminum profile, the rear reinforcing steel plate and the mounting bracket are fixedly connected by assembly bolts.

[0008] The advantages and positive effects of the present invention are:

[0009] The present invention provides a steel-aluminum composite guide rail structure with a reasonable structural design for a vehicle canopy system. Compared with the existing steel guide rail structure, the present invention realizes a steel-aluminum composite structure design by making the main part of the guide rail structure consist of a guide rail aluminum profile and two front and rear reinforcing steel plates. On the basis of ensuring the overall structural strength of the guide rail, the entire guide rail is made lighter, which is conducive to the lightweight design of the entire vehicle canopy system, can reduce the burden on the vehicle, and reduce the fuel consumption of the vehicle. Therefore, compared with the existing steel guide rail, the aluminum alloy and steel plate composite structure of the present guide rail has the characteristics of high structural strength and light weight.

[0010] By making the upper part of the profile body of the guide rail aluminum profile have an arc-shaped upper rail surface and the lower part has an arc-shaped lower rail surface, the upper and lower rail surfaces of the guide rail structure can both contact the rollers. Therefore, after the upper rail surface is worn, the guide rail can be disassembled and reversed to transfer the lower rail surface to the upper part for continued use. Therefore, the utilization rate of the guide rail structure is high and material waste is avoided. Compared with the existing steel guide rails, the composite guide rail in the present invention supports a segmented design. In this way, when some of the guide rail sections are deformed, damaged, worn, etc., only the section of the guide rail can be disassembled and replaced, and the other guide rail sections remain unchanged. Therefore, it is easy to perform maintenance operations (i.e., easy to repair) and reduce the operating intensity of maintenance operations, thereby reducing the cost of maintenance operations.

[0011] After the mounting bracket of the guide rail structure is welded and fixed to the side of the vehicle, other components are fixedly connected to the mounting bracket by assembly bolts. Therefore, when maintenance operations are performed on the main part of the guide rail structure (such as replacing the guide rail section, turning the guide rail direction to move the lower rail surface to the upper part after the upper rail surface is worn), it can be performed without cutting the mounting bracket, so there will be no damage to the side of the vehicle.

[0012] Preferably: a middle profile hole is provided in the middle of the profile body, side profile holes are provided above and below the middle profile hole, and the extension direction of the side profile holes and the middle profile hole is parallel to the length direction of the profile body.

[0013] Preferably: the front groove and the rear groove have the same size, the width of the front reinforcing steel plate is equal to the width of the front groove, the thickness of the front reinforcing steel plate is equal to the depth of the front groove, the width of the rear reinforcing steel plate is equal to the width of the rear groove, and the thickness of the rear reinforcing steel plate is equal to the depth of the rear groove.

[0014] Preferably: the mounting bracket is U-shaped as a whole and is made by bending the same metal plate; it includes a connecting plate located in the middle and fixing plates located on both sides, the connecting plate abuts against the rear reinforcing steel plate, and the rear edges of the two fixing plates are welded and fixed to the vehicle side.

[0024] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0025] See also Figure 1 and Figure 2 The steel-aluminum composite rail structure for a vehicle canopy system of the present invention comprises a rail aluminum profile 1, a reinforcing steel plate and a mounting bracket 4. The rail aluminum profile 1 is used as the basic part of the rail structure. By making the basic part of the rail with aluminum alloy, the lightweight design of the rail structure is realized. The reinforcing steel plate is used to ensure the structural strength of the entire rail structure, so that the rail structure meets the use requirements of the vehicle canopy system. The mounting bracket 4 is used to fix the rail structure to the side of the vehicle.

[0026] The guide rail structure is a composite structure guide rail composed of aluminum alloy profiles and steel plates, which realizes the overall lightweight design while ensuring the overall structural strength. Therefore, the guide rail structure is conducive to the lightweight design of the vehicle canopy system, and the lightweight canopy system can reduce the burden on the vehicle and reduce fuel consumption.

[0027] See also Figure 3 , we can see that:

[0028] The guide rail aluminum profile 1 includes a profile body 1-1 made of aluminum alloy, an arc-shaped upper rail surface 1-6 is provided at the top of the profile body 1-1, an arc-shaped lower rail surface 1-7 is provided at the bottom, a front groove 1-4 is provided in the front middle of the profile body 1-1, and a rear groove 1-5 is provided in the rear middle. The contours of the upper rail surface 1-6 and the lower rail surface 1-7 are consistent with the contours of the rollers rolling along the guide rail structure, and the front groove 1-4 and the rear groove 1-5 are used to install the reinforcing steel plate.

[0029] Since the upper part of the profile body 1-1 is provided with an upper rail surface 1-6 and the lower part is provided with a lower rail surface 1-7, after the upper rail surface 1-6 is worn, the guide rail aluminum profile 1 can be disassembled, the upper rail surface 1-6 is turned downward, and the lower rail surface 1-7 is turned upward for use. Therefore, compared with the existing steel guide rail structure, the guide rail structure in the present invention can be reused, that is, after the guide rail is worn, the direction of the guide rail aluminum profile 1 can be turned to achieve secondary use instead of being discarded as waste. Therefore, the guide rail structure can be reused, reducing material waste.

[0030] The guide rail aluminum profile 1 is made of aluminum alloy and formed by an integrated extrusion process. In this embodiment, a middle profile hole 1-3 is provided in the middle of the profile body 1-1, and side profile holes 1-2 are provided above and below the middle profile hole 1-3. The extension direction of the side profile hole 1-2 and the middle profile hole 1-3 is parallel to the length direction of the profile body 1-1. As shown in the figure, the middle profile hole 1-3 is a circular hole, the side profile hole 1-2 is a circular hole, and the middle profile hole 1-3 is provided with two upper and lower ones. Providing the side profile hole 1-2 and the middle profile hole 1-3 on the profile body 1-1 can reduce the weight of the guide rail aluminum profile 1 and further improve the lightweight level of the guide rail structure.

[0031] The reinforcing steel plate includes a front reinforcing steel plate 2 and a rear reinforcing steel plate 3. As shown in the figure, the front reinforcing steel plate 2 is arranged in the front groove 1-4, and the rear reinforcing steel plate 3 is arranged in the rear groove 1-5. In this embodiment, the sizes of the front groove 1-4 and the rear groove 1-5 are the same, that is, the width of the front groove 1-4 is equal to the width of the rear groove 1-5, the depth of the front groove 1-4 is equal to the depth of the rear groove 1-5, the width of the front reinforcing steel plate 2 is equal to the width of the front groove 1-3, the thickness of the front reinforcing steel plate 2 is equal to the depth of the front groove 1-4, the width of the rear reinforcing steel plate 3 is equal to the width of the rear groove 1-5, and the thickness of the rear reinforcing steel plate 3 is equal to the depth of the rear groove 1-5. Therefore, when the front steel plate 2 is placed in the front groove 1-4 and the rear steel plate 3 is placed in the rear groove 1-5, the front groove 1-4 and the rear groove 1-5 of the guide rail aluminum profile 1 are completely occupied, and the reinforcing steel plate will not protrude from the groove.

[0032] The mounting bracket 4 is located behind the rear reinforcement steel plate 3, and the front reinforcement steel plate 2, the guide rail aluminum profile 1, the rear reinforcement steel plate 3 and the mounting bracket 4 are fixedly connected by assembly bolts 5. Therefore, the assembly consisting of the front reinforcement steel plate 2, the guide rail aluminum profile 1 and the rear reinforcement steel plate 3 can be disassembled from the mounting bracket 4, and the mounting bracket 4 is fixedly connected to the side of the vehicle (usually welded), and the detachable structure makes the installation and maintenance of the guide rail structure convenient and labor-saving.

[0033] See also Figure 4 and Figure 5 , we can see that:

[0034] The mounting bracket 4 is in a U-shape as a whole and is made by bending the same metal plate. It includes a connecting plate 4-1 located in the middle and fixing plates 4-2 located on both sides. The connecting plate 4-1 abuts against the rear reinforcing steel plate 3. The rear edges of the two fixing plates 4-2 are welded and fixed to the side of the vehicle. After the mounting bracket 4 is welded and fixed to the side of the vehicle, it is generally not removed from the side of the vehicle. The mounting bracket 4 is preferably made of a metal plate material consistent with the material of the side of the vehicle, which is conducive to ensuring the strength of the connection structure after welding and installation.

[0035] In this embodiment, connection holes are provided on the front reinforcing steel plate 2, the profile body 1-1, the rear reinforcing steel plate 3 and the connecting plate 4-1, and the assembly bolts 5 pass through the corresponding connection holes. As shown in the figure, the connection holes on the front reinforcing steel plate 2 and the rear reinforcing plate 3 are arranged in the middle of the reinforcing steel plates, the connection holes on the profile body 1-1 are arranged in the middle of the profile body 1-1, and pass through horizontally between the two middle profile holes 1-3, and the connection holes on the connecting plate 4-1 are located in the middle of the plate body.

[0036] like Figure 5 As shown in the figure, the connecting holes on the connecting plate 4-1 in this embodiment are strip holes, which can provide a certain margin for the installation of the main part of the guide rail structure and avoid the problem of the connecting holes being unable to be accurately aligned due to the position accuracy problem of the welding installation of the mounting bracket 4 on the vehicle side.

[0037] In this embodiment, the connection hole on the front reinforcing steel plate 2 is a countersunk connection hole, and the assembly bolt 5 has a countersunk nut and the countersunk nut is located in the countersunk connection hole. As shown in the figure, the countersunk nut of the assembly bolt 5 is conical, and the countersunk connection hole also has an adaptive conical shape, so that when the assembly bolt 5 is tightened, the countersunk nut fully falls into the countersunk connection hole, and no protrusions are formed on the surface of the front reinforcing steel plate 2, so that the surface of the guide rail structure is regular and has no protrusions.

[0038] Directions:

[0039] According to the length of the vehicle's cargo box, select a suitable number of sections of the guide rail structure to form a complete canopy system guide rail, and the sum of the lengths of the sections of the guide rail structure is equal to the design length of the guide rail;

[0040] The position is measured and marked on the side of the vehicle to accurately determine the specific position of each mounting bracket 4, and then each mounting bracket 4 is fixedly installed on the side of the vehicle by welding;

[0041] Then, the main part of the guide rail structure is installed to the front of each mounting bracket 4, that is, the front reinforcing steel plate 2 is arranged in the front groove 1-4 of the guide rail aluminum profile 1 of each guide rail structure, and the rear reinforcing steel plate 3 is arranged in the rear groove 1-5, and then the assembly bolt 5 is inserted into the corresponding connection hole, and the rear end of the assembly bolt 5 is passed through the connection hole on the connection plate 4-1 of the corresponding mounting bracket 4, and the nut is tightened to realize the assembly connection between the main part of the guide rail structure and the mounting bracket 4;

[0042] It is worth noting that in order to improve the integrity of the guide rail of the canopy system, the length of the front reinforcing steel plate 2 and / or the rear reinforcing steel plate 3 can be made unequal to the length of the guide rail aluminum profile 1, so that adjacent guide rail aluminum profiles 1 are connected in sequence, and the front reinforcing steel plate 2 and / or the rear reinforcing steel plate 3 will overlap between adjacent guide rail aluminum profiles 1, that is, a part of the front reinforcing steel plate 2 and / or the rear reinforcing steel plate 3 is located in the groove of the guide rail aluminum profile 1, and the other part is located in the corresponding groove of the previous or next guide rail aluminum profile 1, so that each guide rail structure is connected in sequence, and the constructed guide rail has stronger integrity and higher structural strength.

[0043] Maintenance method:

[0044] When the upper part of some guide rail structures, that is, the upper rail surface 1-6, is worn out after a certain period of use and is not suitable for continued use, the guide rail can be disassembled, and the excessively worn guide rail aluminum profile 1 is turned over, so that its upper rail surface 1-6 is transferred to the bottom and the lower rail surface 1-7 is transferred to the top, and then the front reinforcement steel plate 2, the guide rail aluminum profile 1 and the rear reinforcement steel plate 3 are reassembled on the mounting bracket 4 to form a complete guide rail. In this case, the roller of the canopy system contacts the rail surface transferred to the top;

[0045] When some guide rail structures need to be replaced due to deformation, damage, excessive wear, etc., the guide rail can be disassembled, the problematic section of the guide rail structure can be removed, and a new guide rail structure can be replaced and reassembled to form a complete awning system guide rail.
