[0003] Existing high and low voltage wire harness fixing devices generally suffer from fixed structures and non-adjustable dimensions, making it difficult to flexibly adjust according to the actual number and arrangement of wire harnesses. This results in poor adaptability for fixing high and low voltage wire harnesses or multiple wire harnesses in different scenarios.

This makes positioning difficult and inefficient during installation, and the connection is prone to loosening due to factors such as vibration, resulting in insufficient fixing firmness. In addition, the fixing device lacks an effective reinforcement structure on its outer periphery, resulting in weak overall rigidity. It is difficult to stably bear the stress when fixing multiple wire harnesses, and local deformation is prone to occur, affecting the stability and safety of wire harness fixing.

[0030] As shown in Figure 5, a long-side reinforcing protrusion 221 is provided at the inner center of the long-side reinforcing member 220. The long-side reinforcing member 220 is connected to the fixed base 100 through the long-side reinforcing protrusion 221.

The long-side reinforcing member 220 is provided with a long-side reinforcing protrusion 221 at the inner center of the long-side reinforcing member 220 and The embedded strip magnetic core 400, the long-side reinforcing slots 222 on the upper and lower surfaces, the long-side reinforcing arc-shaped protrusions 223 at both ends, and the embedded strip magnetic core 400 together achieve linear reinforcement of the long side of the fixing base 100. The central long-side reinforcing protrusion 221 is connected to the fixing base groove 114 of the fixing base unit 110 through the strip magnetic core 400 with opposite magnetic properties and mechanical engagement, which can disperse the stress in the long side direction and prevent stress from causing damage in the middle of the long side. The curved protrusion 223 of the long side reinforcement and the corner reinforcement arc groove 213 of the corner reinforcement 210 are tightly connected by the strip magnetic core 400 with opposite magnetic properties and the arc surface to ensure a stable transition between the long side and the corner; the upper and lower long side reinforcement slots 222 cooperate with the locking protrusion of the reinforcement cover plate 240 to lock the position of the long side reinforcement 220, and work together with the corner reinforcement 210 to enhance the structural stability of the long side of the fixed base 100 and improve the overall vibration resistance.
[0031] As shown in Figure 5, both the upper and lower surfaces of the short-side reinforcement member 230 are provided with short-side reinforcement slots 231. The short-side reinforcement member 230 is covered by the reinforcement cover plate 240 through the short-side reinforcement slots 231. Both connecting ends of the short-side reinforcement member 230 are provided with short-side reinforcement arc-shaped protrusions 232.

The short-side reinforcement member 230 is characterized by short-side reinforcement protrusions and embedded strip-shaped magnetic cores 400, short-side reinforcement slots 231 on the upper and lower surfaces, and short-side reinforcement arc-shaped protrusions at both ends. The protrusion 232 and the embedded strip magnetic core 400 achieve adaptive reinforcement of the short side of the fixed base 100: the short side reinforcement protrusion and the fixed base groove 114 of the fixed base unit 110 are connected by the strip magnetic core 400 with opposite magnetic properties and mechanical fitting, which enhances the stability of the short side connection; the short side reinforcement arc protrusion 232 cooperates with the corner reinforcement arc groove 213 of the corner reinforcement component 210 to ensure a tight connection between the short side and the corner, and avoid gaps between the short side and the corner; the upper and lower short side reinforcement slots 231 cooperate with the locking protrusion of the reinforcement cover plate 240 to lock the position of the short side reinforcement component 230, and together with the long side reinforcement component 220 and the corner reinforcement component 210, form a complete peripheral reinforcement system, so that each peripheral side of the fixed base 100 is specifically reinforced, and the overall structural rigidity is significantly improved.
[0032] The fixed base unit 110 has four corner openings with cover holes 115. The reinforcing cover plate 240 is an annular body. The reinforcing cover plate 240 is provided with a reinforcing cover protrusion 241 corresponding to the cover holes 115. As shown in Figure 6, the reinforcing cover plate 240 is provided with a reinforcing cover protrusion 242 corresponding to the corner reinforcing slot 212 of the corner reinforcement member 210, the long side reinforcing slot 222 of the long side reinforcement member 220, and the short side reinforcing slot 231 of the short side reinforcement member 230. The reinforcing cover plate 240 is closed with the fixed base body 100 and the splicing reinforcing assembly 200 through the reinforcing cover protrusion 241 and the reinforcing cover protrusion 242. The four corners are provided with cover holes 115. The reinforcing cover plate 240 is annular, with corresponding reinforcing cover protrusions 241 and 242. The reinforcing cover plate 240 is double-positioned by inserting the reinforcing cover protrusions 241 into the cover holes 115 of the fixing unit 110 and the reinforcing cover protrusions 242 into the slots of each reinforcing component. This tightly covers the fixing unit 100 and the splicing reinforcing component 200 into a closed whole. The annular design of the reinforcing cover plate 240 does not occupy the installation space of the wire harness assembly 300. At the same time, the multi-point positioning further restricts the relative displacement of each component, improving the integrity and vibration resistance of the overall structure. The cover connection can also reduce the entry of external dust and impurities into the splicing gaps of the fixing unit 100, providing auxiliary protection for the wire harness and extending the service life of the fixing device.

Figure 1 In this embodiment, the suction cup is disposed on the fixing stepped hole of the corner reinforcement 210; the through hole of the reinforcement cover plate 240 avoids the fixing stepped hole, does not affect the installation operation, significantly improves the installation scenario adaptability of the fixture, and meets the installation needs of multiple scenarios such as vehicle, industrial equipment, and home.
[0034] The magnetic properties of the strip magnetic core 400 of the fixing seat protrusion 113 are opposite to those of the strip magnetic core 400 of the fixing seat groove 114. The magnetic properties of the strip magnetic core 400 of the fixing seat groove 114 are opposite to those of the strip magnetic core 400 of the corner-reinforced protrusion 211, the long-side-reinforced protrusion 221, and the short-side-reinforced protrusion. The magnetic properties of the strip magnetic core 400 of the corner-reinforced arc-shaped groove 213 are opposite to those of the strip magnetic core 400 of the long-side-reinforced arc-shaped protrusion 223 and the short-side-reinforced arc-shaped protrusion 232. The magnetic properties of the strip-shaped magnetic core 400 are opposite. This application ensures that each splicing connection part forms a magnetic pre-fixation with opposite attraction through reasonable magnetic core magnetic settings: during splicing, the magnetic attraction automatically guides the protrusion and groove to fit precisely, simplifying installation and positioning; in conjunction with the fitting and limiting of the mechanical structure, such as the matching shape of the protrusion and groove and the fitting of the arc surface, a dual connection of magnetic pre-fixation and mechanical anti-detachment is achieved, avoiding the problem of easy loosening in traditional pure mechanical splicing and significantly improving the connection firmness; at the same time, the magnetic pre-fixation can complete the initial splicing without tools, improving installation efficiency and making disassembly and maintenance more convenient.
