Description

Technical Field

[0001] The utility model relates to the technical field of truck accessories, in particular to a riveted truck centralized controller frame. Background Art

[0002] Guided by the national "dual carbon" goals, some traditional resource-based regions such as Ordos and Tangshan are facing pressure to transform to new energy. Local governments are encouraging the development of new energy heavy-duty trucks through subsidies and the establishment of penetration targets. At the same time, under the dual effects of strict supervision and economic subsidies, high-pollution and high-emission enterprises are subject to policy constraints and generally choose to prioritize the replacement of fuel heavy-duty trucks, a high-emission link, as one of the most suitable solutions to ensure the company's operating rate and economic benefits. This has objectively promoted the demand for electric heavy-duty trucks at the industrial terminal. As the control center of new energy trucks, the centralized controller is responsible for processing data exchange, energy management, safety control, and coordinating the power, economy, safety, and comfort of the entire vehicle. It is an important core component and requires special protection during use. This project develops a new structure of riveted galvanized frame to implement frame protection around the centralized controller.

[0003] The traditional riveted galvanized frame is widely used in current centralized controller protection frame designs. Although this frame is popular for its cost-effectiveness and ease of manufacturing, it has exposed a series of problems in actual use, especially in terms of strength and stability. The existing riveted galvanized frame shell is usually composed of thin steel plates, formed through simple bending and stamping processes, and connected and fixed with rivets. Although this structure can meet basic installation requirements, its inherent material selection and processing method limit the overall rigidity of the frame, making it prone to distortion and deformation under external impact or prolonged load.

[0004] From a material perspective, to control costs, thinner galvanized sheets are often used. While these sheets offer good corrosion resistance, they lack sufficient mechanical strength to withstand pressure from various directions. This is especially true in industrial environments, where centralized controllers may need to withstand forces from all angles, such as vibration, impact, and even instantaneous impacts from accidental drops. Once a load exceeds its bearing capacity, the existing frame is likely to undergo irreversible deformation, impacting the safety and normal operation of the internal equipment.

[0005] There are also obvious deficiencies in structural design; traditional frames often only consider basic supporting functions and ignore overall coordination; for example, certain parts may suffer from excessive local stress due to concentrated force, thus becoming the weakest link in the entire structure; at the same time, due to the lack of effective reinforcement measures, the frame is more prone to fatigue damage during long-term use, reducing its service life; in addition, simple and rough connection methods - such as excessive reliance on rivets rather than welding or other more secure methods - further weaken the overall stability and tensile strength of the frame, increasing potential risks.

[0006] Therefore, how to provide a riveted truck centralized controller framework is a problem that those skilled in the art urgently need to solve. Utility Model Content

[0007] One purpose of the present invention is to propose a riveted truck centralized controller frame. The galvanized layer on the surface of the frame base and the frame side panels of the present invention separates the air from the steel base. The air will first corrode the galvanized layer, and the products of zinc corrosion (zinc hydroxide, zinc oxide and zinc carbonate) will form a dense thin layer insoluble in water on the surface of the galvanized layer, slowing down the corrosion rate of the galvanized layer and extending the service life of the frame; the rivets, locating pins, nut columns and bolts on the frame base and the frame side panels are fixed by a riveting process, which can avoid the high temperature generated by the welding process from damaging the galvanized layer, maintain the integrity of the galvanized layer on the surface of the frame, and reduce the subsequent anti-rust treatment work; the setting of the triangular grooves of the triangular reinforcement ribs at the bending parts on both sides of the frame changes the stress-strain state, balances the internal stress, and can strengthen the shell strength of the frame, increase the rigidity, and effectively prevent the frame from twisting and deformation.

[0008] According to an embodiment of the present invention, a riveted truck centralized controller frame includes a frame base, frame side panels, rivets, locating pins, nut columns and bolts, wherein the bottom of the frame side panels are fixedly mounted on both sides of the frame base, the bottom of the rivets are fixedly mounted on the top of the frame base, the bottom of the locating pins are fixedly mounted on the top of the frame base, and the bottom of the bolts are fixedly mounted on the frame side panels.

[0010] Furthermore, mounting grooves are provided on outer surfaces of the first bending base frame and the second bending base frame.

[0011] Furthermore, a straight stripe groove is provided at the bottom of the frame base, and a breakpoint stripe groove is provided at the bottom of the frame base, and the straight stripe groove and the breakpoint stripe groove are intersected and vertically arranged.

[0012] Furthermore, a through groove is provided on the outer surface of the frame side plate, and a through hole is provided on the outer surface of the frame side plate.

The air will first corrode the galvanized layer, and the products of zinc corrosion (zinc hydroxide, zinc oxide and zinc carbonate) will form a dense thin layer insoluble in water on the surface of the galvanized layer, which slows down the corrosion rate of the galvanized layer and extends the service life of the frame; the rivets, positioning pins, nut columns and bolts on the frame base and the frame side panels are fixed by a riveting process, which can avoid the high temperature generated by the welding process from damaging the galvanized layer, maintain the integrity of the galvanized layer on the surface of the frame, and reduce the subsequent rust prevention work; the setting of the triangular grooves of the triangular reinforcement ribs at the bending parts on both sides of the frame changes the stress-strain state, balances the internal stress, can strengthen the shell strength of the frame, increase the rigidity, and effectively prevent the frame from twisting and deformation.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0027] The traditional riveted galvanized frame is widely used in current centralized controller protection frame designs. Although this frame is popular for its cost-effectiveness and ease of manufacturing, it has exposed a series of problems in actual use, especially in terms of strength and stability. The existing riveted galvanized frame shell is usually composed of thin steel plates, formed through simple bending and stamping processes, and connected and fixed with rivets. Although this structure can meet basic installation requirements, its inherent material selection and processing method limit the overall rigidity of the frame, making it prone to distortion and deformation under external impact or prolonged load.

[0028] From a material perspective, to control costs, thinner galvanized sheets are often used. While these sheets offer good corrosion resistance, they lack sufficient mechanical strength to withstand pressure from various directions. This is especially true in industrial environments, where centralized controllers may need to withstand forces from all angles, such as vibration, impact, and even instantaneous impacts from accidental drops. Once a load exceeds its bearing capacity, the existing frame is likely to undergo irreversible deformation, impacting the safety and normal operation of the internal equipment.

[0029] There are also obvious deficiencies in structural design; traditional frames often only consider basic supporting functions and ignore overall coordination; for example, certain parts may suffer from excessive local stress due to concentrated force, thus becoming the weakest link in the entire structure; at the same time, due to the lack of effective reinforcement measures, the frame is more prone to fatigue damage during long-term use, reducing its service life; in addition, simple and rough connection methods - such as excessive reliance on rivets rather than welding or other more secure methods - further weaken the overall stability and tensile strength of the frame, increasing potential risks.

[0030] Taking into account the influence of environmental factors, the existing riveted galvanized frames also face the problem of poor weather resistance; although galvanizing can delay the oxidation and rusting process of the metal surface to a certain extent, the protective effect under extreme conditions (such as high humidity, salt spray erosion, etc.) is not ideal; over time, the exposed parts may gradually lose their original gloss and even begin to corrode, which not only affects the aesthetics, but more importantly, it will accelerate the aging process of the material and reduce the overall safety of the frame.

[0031] To solve the above problems, the following solutions are proposed:

[0032] Please refer to Figures 1 to 6 The utility model provides a riveted truck centralized controller frame, including a frame base 1, a frame side panel 2, a rivet 3, a positioning pin 4, a nut column 5 and a bolt 6, wherein the bottom of the frame side panel 2 is fixedly installed on both sides of the frame base 1, the frame base 1 and the frame side panel 2 are perpendicular to each other, and the surface is not allowed to have sharp edges and spikes, cracks, defects, metal wires, red rust, oil stains, and obvious indentations; the cut surface is allowed to be chamfered to C0.4MAX to remove sharp edges, the bottom of the rivet 3 is fixedly installed on the top of the frame base 1, the bottom of the positioning pin 4 is fixedly installed on the top of the frame base 1, and the bottom of the bolt 6 is fixedly installed on the frame side panel 2.

[0033] Specifically, a first bending base frame 1.1 is fixedly provided on one side of the bottom of the frame base 1, and a second bending base frame 1.2 is fixedly provided on the other side of the bottom of the frame base 1. The outer surfaces of the first bending base frame 1.1 and the second bending base frame 1.2 are provided with mounting grooves 1.3, a straight stripe groove 1.4 is provided at the bottom of the frame base 1, and a breakpoint stripe groove 1.5 is provided at the bottom of the frame base 1. The straight stripe groove 1.4 and the breakpoint stripe groove 1.5 are cross-shaped and vertically arranged.

[0034] More specifically, a through groove 2.1 is provided on the outer surface of the frame side panel 2, a through hole 2.2 is provided on the outer surface of the frame side panel 2, a plurality of rivets 3 and nut columns 5 are respectively provided, and the plurality of rivets 3 are distributed on the top of the frame base 1, and two locating pins 4 are provided, and the two locating pins 4 are distributed at the diagonals of the top of the frame base 1.

[0035] More specifically, the frame base 1 and the frame side panels 2 are arranged vertically, and a triangular groove 7 is provided at the bottom of the intersection of the frame base 1 and the frame side panels 2 .

[0036] The bottom of the frame base 1 is a salt spray test surface, and its RA is ≥5 in a 6-hour neutral salt spray test.

[0037] The riveting strength of the rivet 3 and the nut column 5 is greater than or equal to 1750N, and the riveting strength of the bolt 6 is greater than or equal to 1860N.

[0038] The galvanized layer on the surface of the frame base 1 and the frame side panels 2 separates the air from the steel base. The air will first corrode the galvanized layer, and the products of zinc corrosion (zinc hydroxide, zinc oxide and zinc carbonate) will form a dense thin layer insoluble in water on the surface of the galvanized layer, slowing down the corrosion rate of the galvanized layer and extending the service life of the frame; the rivets 3, locating pins 4, nut columns 5 and bolts 6 on the frame base 1 and the frame side panels 2 are fixed with a riveting process, which can avoid the high temperature generated by the welding process from damaging the galvanized layer, maintain the integrity of the galvanized layer on the surface of the frame, and reduce the subsequent rust prevention work; the setting of the triangular grooves 7 of the triangular reinforcement ribs at the bends on both sides of the frame changes the stress-strain state, balances the internal stress, strengthens the shell strength of the frame, increases the rigidity, and effectively prevents the frame from twisting and deformation.

[0039] When producing the frame, the galvanized sheet is moved and placed on the lower stamping die, and the upper die base, pressure plate and punch move downward. The pressure plate first presses the sheet against the lower die base. Under the action of the compression spring, the upper die base and punch continue to move downward, and the bending die cooperates with the bending groove to complete the wide side bending of the sheet; while the punch completes the punching of the sheet's wire harness reserved holes according to the reserved holes, the narrow side pressure plate and punch work, and the pressure plate moves to the predetermined point to bend the side, and the punch punches the heat dissipation holes and plug holes according to the reserved holes; this realizes the one-time forming of the bending and punching of the galvanized sheet, improves production efficiency, reduces processing errors, and improves product quality.

[0040] In the protective flatness detection technology, laser rangefinders are arranged in the horizontal and vertical directions of the frame above the detection station. A groove is opened on the upper part of the base of the detection platform, and rubber rollers are provided above the grooves respectively. Combined with the elastic limit structure set on both sides of the conveying direction, it can prevent the frame from deviating and avoid damage to the frame surface during the detection process, thereby ensuring the integrity of the frame surface; during the frame production inspection, the rangefinder scans the frame plane and adopts rectangular grid sampling to obtain multi-point data of the frame plane. The height difference at different positions is used to measure the flatness of the frame to ensure the product qualification rate.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
