[0029] This utility model proposes a charging pile spring assembly.
[0030] Please see Figures 1 to 5In one embodiment of the present invention, the charging pile spring assembly includes a spring body 10 and at least two machined parts 20; the two machined parts 20 are respectively sleeved on both ends of the spring body 10 and electroplated with both ends of the spring body 10; each machined part 20 is provided with at least one drainage groove 20a on the outer wall of the electroplating position of the spring body 10, and the drainage groove 20a is used to discharge electroplating residue.
[0031] Each component 20 and the outer wall of the spring body 10 where electroplating is performed has at least one drainage groove 20a. The drainage groove 20a is used to discharge residual electroplating liquid. The design of the drainage groove 20a makes the discharge of residual electroplating liquid smoother and avoids corrosion of the product surface by the residual liquid. This design effectively solves the problem of ineffective discharge of residual electroplating liquid in the prior art, avoids the corrosive effect of residual electroplating liquid on the spring body 10 and component 20, and improves the product quality of the charging pile spring assembly. Due to the design of the drainage groove 20a, residual electroplating liquid can be discharged quickly, making the electroplating process smoother, thereby improving the electroplating speed and quality and ensuring the service life of the charging pile spring assembly.
[0032] In one embodiment, please refer to Figures 1 to 5 The drainage channel 20a is provided to extend along the axial direction of the vehicle part 20.
[0033] In terms of structural design, the drainage channel 20a is set to extend along the axial direction of the machine part 20. This design makes the extension direction of the drainage channel 20a form an angle with the extension direction of the spring body 10, so that the electroplating liquid flowing in the drainage channel 20a is separated from the spring body 10, reducing the turbulence and eddy current phenomenon of the electroplating liquid inside the machine part 20, making the flow of the electroplating liquid inside the machine part 20 smoother, and thus achieving higher electroplating liquid transmission efficiency.
[0034] In one embodiment, please refer to Figures 1 to 5 The outer wall of the part 20 and the spring body 10 where they are electroplated is provided with four drainage grooves 20a, which are evenly spaced around the outer wall of the part 20.
[0035] Four drainage channels 20a are evenly spaced around the outer wall of the machined part 20. This layout maximizes the fluidity and coverage of the solution. The evenly spaced drainage channels 20a make the discharge of residual electroplating solution after electroplating more efficient, thereby improving electroplating efficiency. There are four drainage channels 20a located on the outer wall of the machined part 20 and the electroplating area of the spring body 10. The drainage channels 20a are evenly spaced around the outer wall of the machined part 20, and each channel 20a has the same shape and size to ensure uniform drainage of the electroplating solution after electroplating.
[0036] In one embodiment, please refer to Figures 1 to 5 The diversion channel 20a can be a straight diversion channel 20a, a wavy diversion channel 20a, or a corrugated diversion channel 20a.
[0037] The flow channel 20a design in this embodiment, whether straight, wavy, or zigzag, can effectively guide the flow of the electroplating solution and accelerate its flow rate. Compared with traditional flow channels, the flow channel 20a can better control the direction of the electroplating solution and reduce energy loss during the flow process.
[0038] The design of the straight-line drainage channel 20a effectively reduces the resistance of the electroplating solution during the flow process, allowing the electroplating solution to flow faster. The wavy drainage channel 20a and the corrugated drainage channel 20a further extend the drainage path, increase the drainage volume of the machined part 20, and thus improve the drainage efficiency of the drainage channel 20a.
[0039] In one embodiment, please refer to Figures 1 to 5 The radial cross-sectional shape of the drainage channel 20a is semi-circular, rectangular, triangular or trapezoidal.
[0040] Due to the optimized cross-sectional shape, the electroplating solution flows more uniformly within the diversion channel 20a, reducing turbulence and eddies, thereby improving the flow stability of the electroplating solution and preventing impact and damage to the machined part 20 and spring body 10 caused by unstable flow. Different cross-sectional shapes of the diversion channel 20a can better adapt to the electroplating solution distribution requirements under different working conditions. For example, a semi-circular cross-section is suitable for applications with larger flow rates and higher velocities, while rectangular and triangular cross-sections are more suitable for applications with lower velocities and smaller flow rates. This design makes the distribution of the electroplating solution within the diversion channel 20a more uniform, contributing to improved overall work efficiency.
[0041] In one embodiment, please refer to Figures 1 to 5 Each component 20 includes a component body 21 and a limiting boss 22 provided on the outer wall of the component body 21. The limiting boss 22 is arranged around the periphery of the component body 21 and is spaced apart from the end of the component body 21. The spring body 10 is sleeved on the outer wall of the component body 21 and abuts against the limiting boss 22. The component body 21 is provided with a drainage groove 20a.
[0042] The machined part body 21 is provided with a drainage groove 20a. This design can prevent the electroplating process from accumulating inside the machined part 20, thereby avoiding corrosion and damage caused by liquid accumulation, and also improving the self-cleaning ability of the machined part 20. A limiting boss 22 is provided on the machined part body 21. The limiting boss 22 can limit the engagement position of the spring body 10, so that the spring body 10 will not directly and completely penetrate the machined part 20, ensuring that the machined part 20 and the spring body 10 can be properly assembled.
[0043] In one embodiment, please refer to Figures 1 to 5The depth of the drainage groove 20a gradually increases from the end of the vehicle body 21 away from the limiting boss 22 towards the end of the vehicle body 21 where the limiting boss 22 is located.
[0044] In this embodiment, the depth of the drainage channel 20a is gradually increased in one direction, and the direction of gradual increase is from the end away from the limiting boss 22 to the end closer to the limiting boss 22. In this way, the depth of the drainage channel 20a at the end away from the limiting boss 22 is maximized, so that the end of the drainage channel 20a away from the limiting boss 22 can more quickly guide the electroplating solution to the end of the drainage channel 20a close to the limiting boss 22, thereby improving the drainage efficiency of the drainage channel 20a.
[0045] As the depth of the flow channel 20a gradually increases, the fluid is better guided during flow, thus avoiding localized wear or damage caused by fluid impact or excessive flow velocity. This improves the service life and reliability of the machined part 20 to some extent. This design helps improve the adaptability of the machined part 20 in complex working environments. Because the depth of the flow channel 20a gradually increases, the fluid velocity and flow rate can be adjusted as needed in different working environments, thereby meeting the usage requirements under different operating conditions.
[0046] In one embodiment, please refer to Figures 1 to 5 The limiting boss 22 has at least one extended groove 20b on the side that abuts against the spring body 10, and the extended groove 20b is connected to the drainage groove 20a.
[0047] In this embodiment, at least one extended groove 20b is recessed on the side of the limiting boss 22 facing the spring body 10. The connection between the extended groove 20b and the drainage groove 20a forms an effective drainage channel. This design not only optimizes the flow path of the electroplating solution, but also improves the flow efficiency of the electroplating solution. This allows the electroplating solution coming out of the drainage groove 20a to continue to flow along the extended groove 20b to the limiting boss 22, making the electroplating solution further away from the outer wall of the machine part body 21 and the outer wall of the spring body 10, further improving the drainage effect of the machine part 20.
[0048] Optionally, the number of extension grooves 20b provided on the limiting boss 22 is the same as the number of drainage grooves 20a provided on the machine body 21.
[0049] Optionally, the shape and arrangement of the extension groove 20b are the same as those of the guide groove 20a.
[0050] In one embodiment, please refer to Figures 1 to 5 The depth of the epitaxial groove 20b is greater than the depth of the drainage groove 20a.
[0051] In this embodiment, the depth of the epitaxial tank 20b is set differently from the depth of the drainage tank 20a, and the depth of the epitaxial tank 20b is set greater than the depth of the drainage tank 20a. This setting allows for a larger drainage flow in the epitaxial tank 20b, further accelerating the drainage speed and preventing the electroplating solution from slowing down and forming blockages at the epitaxial tank 20b. This effectively improves the drainage efficiency, and the structure is simple and easy to implement.
[0052] In one embodiment, please refer to Figures 1 to 5 The extension groove 20b extends from the position where the limiting boss 22 connects with the vehicle body 21 to the edge of the limiting boss 22.
[0053] In this embodiment, the extension groove 20b extends to the edge of the limiting boss 22, so that the electroplating liquid coming out of the drainage groove 20a can continue to flow along the extension groove 20b to the edge of the limiting boss 22, so that the electroplating liquid is further away from the outer wall of the machine part body 21 and the outer wall of the spring body 10, further improving the drainage effect of the machine part 20.
[0054] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
