[0007] The wear-resistant component includes a wear-resistant layer that is attached to and fixed to the inner wall of the arc-shaped cable receiving cavity and wear-resistant blocks embedded on both sides of the adjustable card seat. The wear-resistant blocks are in sliding contact with the side wall of the adjustment groove.

[0008] The locking mechanism includes a threaded hole on one side of the fixed seat and communicating with the adjustment groove, and a locking bolt that is threadedly engaged with the threaded hole.

[0025] 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.

[0026] like Figure 1-4 As shown, this utility model provides a charging gun cable fixing assembly with an adjustable wear-resistant card holder, including a fixing base 1, an adjustable card holder 2, a wear-resistant component 3, and a locking mechanism 4.

[0027] The mounting base 1 serves as the foundation for the entire assembly. Its mounting ears 103 on both sides, through their built-in internal threaded mounting holes 104, allow for secure fixing of the mounting base 1 to an external support (such as a support structure next to a charging station, a wall bracket, etc.) using external bolts. The triangular reinforcing ribs between the mounting ears 103 and the mounting base 1 distribute the external forces borne by the mounting ears 103, preventing deformation or breakage due to long-term stress. This ensures the overall stability of the mounting base 1 and provides reliable foundation support for subsequent cable fixing.

[0028] The fixed base 1 has an adjustment groove 101 extending in the horizontal direction. The adjustment groove 101 is symmetrically provided with guide protrusions 102. The bottom of the adjustable card seat 2 is provided with a guide groove that matches the guide protrusions 102. The adjustable card seat 2 is set in the adjustment groove 101 through the sliding cooperation between the guide groove and the guide protrusions 102. The top of the adjustable card seat 2 is provided with an arc-shaped cable receiving cavity 201.

[0029] The curved cable receiving cavity 201 at the top of the adjustable holder 2 is adapted to the shape of the charging gun cable. In use, the charging gun cable is directly placed into the curved cable receiving cavity 201. The limiting protrusions 202 at both ends of the receiving cavity extend towards the center of the cavity, and the distance between the protrusions matches the diameter range of the charging gun cable. This can initially limit the cable in the axial direction, preventing the cable from sliding freely in the axial direction within the receiving cavity and avoiding failure of fixation or friction with surrounding structures due to cable displacement.

[0030] The wear-resistant component 3 includes a wear-resistant layer 301 that is attached to and fixed to the inner wall of the arc-shaped cable receiving cavity 201 and wear-resistant blocks 302 embedded on both sides of the adjustable card seat 2. The wear-resistant blocks 302 are in sliding contact with the side wall of the adjustment groove 101.

[0031] The wear-resistant layer 301 (ultra-high molecular weight polyethylene material) attached to the inner wall of the arc-shaped cable receiving cavity 201 directly contacts the charging gun cable. When the cable is inserted, removed, or slightly shaken, the wear-resistant layer 301 can replace the adjustable card holder 2 body to rub against the cable, avoiding wear and tear on the card holder body due to long-term friction.

[0032] The wear-resistant blocks 302 embedded on both sides of the adjustable card holder 2 slide in contact with the side wall of the adjustment groove 101. When the adjustable card holder 2 is slidably adjusted, the wear-resistant blocks 302 bear the friction force of the side wall of the adjustment groove 101, preventing wear caused by direct friction between the side wall of the adjustable card holder 2 and the side wall of the adjustment groove 101, and extending the service life of the adjustable card holder 2 and the fixed seat 1.

[0033] Meanwhile, the polytetrafluoroethylene lubricating coating 106 in the guide groove can reduce the sliding friction between the guide protrusion 102 and the guide groove, making the position adjustment of the adjustable card holder 2 smoother, reducing mechanical wear during the sliding process. In addition, the polytetrafluoroethylene material has good corrosion resistance, which can prevent the guide structure from getting stuck due to environmental factors (such as moisture or slightly corrosive media).

[0034] The locking mechanism 4 includes a threaded hole 402 opened on one side of the fixed seat 1 and communicating with the adjustment groove 101, and a locking bolt 401 threadedly engaged with the threaded hole 402. One end of the locking bolt 401 passes through the threaded hole 402 and abuts against the side wall of the adjustable seat 2 to fix the relative position of the adjustable seat 2 and the fixed seat 1.

[0035] When it is necessary to adjust the cable fixing position according to the actual use scenario (such as charging pile location, cable length, operating habits, etc.), the position adjustment can be achieved by the sliding cooperation between the adjustable bracket 2 and the fixed base 1: the guide protrusion 102 in the adjustment groove 101 of the fixed base 1 and the guide groove at the bottom of the adjustable bracket 2 form a sliding pair. The guide protrusion 102 provides precise guidance for the sliding of the adjustable bracket 2, ensuring that the adjustable bracket 2 always moves smoothly in the horizontal direction during the adjustment process, avoiding deviation or jamming.

[0036] After adjustment to the target position, the locking mechanism 4 is used to fix it: rotate the locking bolt 401 so that it moves axially along the threaded hole 402 on one side of the fixed seat 1. When the end of the bolt passes through the threaded hole 402 and abuts against the side wall of the adjustable seat 2, the self-locking force of the bolt and the threaded hole 402 and the friction between the end of the bolt and the adjustable seat 2 limit the sliding of the adjustable seat 2. If the side wall of the adjustable seat 2 is provided with spaced positioning holes 203, the end of the bolt will be embedded in the corresponding positioning hole 203 to form a mechanical positioning fit of "bolt-positioning hole 203", which further improves the locking stability and prevents the adjustable seat 2 from having a small displacement when subjected to force, so as to achieve precise locking of the position.

[0037] Furthermore, the wear-resistant layer 301 is made of ultra-high molecular weight polyethylene material, the thickness of the wear-resistant layer 301 is 1.5-3mm, and the side of the wear-resistant layer 301 away from the inner wall of the arc-shaped cable receiving cavity 201 is provided with anti-slip texture.

[0038] The anti-slip texture on the side of the wear-resistant layer 301 away from the inner wall of the receiving cavity increases the friction between the wear-resistant layer 301 and the charging gun cable, further preventing the cable from slipping in the receiving cavity and improving the stability of the cable fixation; the knob 403 at the end of the locking bolt 401 and the anti-slip ridge on the outer periphery make it easy for the operator to manually rotate the bolt to lock or unlock without the need for additional tools, thus improving the ease of operation.

[0039] The ultra-high molecular weight polyethylene wear-resistant layer 301 (1.5-3mm thick, with excellent wear resistance) protects the contact surface between the cable and the card holder, while the wear-resistant blocks 302 on both sides protect the contact surface between the card holder and the adjustment groove 101, avoiding core sliding and direct wear of contact components. Compared with components without wear-resistant design, the service life can be increased by 3-5 times. The polytetrafluoroethylene lubricating coating 106 not only reduces sliding friction, but also has acid and alkali resistance and anti-aging properties, and can adapt to complex outdoor environments such as humidity and dust, further reducing the risk of component corrosion.

[0040] Furthermore, both ends of the arc-shaped cable receiving cavity 201 are provided with limiting protrusions 202, which extend toward the center of the arc-shaped cable receiving cavity 201, and the distance between the two limiting protrusions 202 is adapted to the diameter range of the charging gun cable.

[0041] The arc-shaped cable receiving cavity 201 achieves radial wrapping of the cable, the limiting protrusion 202 achieves axial limiting, and the locking mechanism 4 (including the positioning hole 203 design) achieves position locking of the adjustable card seat 2. The triple fixing structure works together to effectively prevent the charging gun cable from shifting or falling off due to external forces (such as pulling or wind shaking), ensuring that the cable is always in a stable and fixed state during the charging process, reducing problems such as charging interruption and poor contact caused by cable loosening.

[0042] Furthermore, the adjustment groove 101 is provided with limiting blocks at both ends to prevent the adjustable card seat 2 from dislodging from both ends of the adjustment groove 101. The limiting blocks are integrally formed with the fixed base 1, and the height of the limiting blocks is not lower than the height of the adjustable card seat 2.

[0043] The wear-resistant layer 301 is in direct contact with the cable, which can prevent the outer insulation layer of the cable from being damaged due to long-term friction, and prevent safety accidents such as leakage and short circuit caused by insulation layer damage, thus providing safety protection for the charging process; the anti-slip texture reduces cable slippage and prevents the cable from pulling on the charging gun interface due to slippage, thus preventing problems such as electric sparks and overheating caused by loose interface.

[0044] Furthermore, the locking bolt 401 has a knob 403 at the end away from the adjustable retainer 2. The outer peripheral wall of the knob 403 has anti-slip textures, and the knob 403 is integrally formed with the locking bolt 401. The knob 403 design of the locking bolt 401, combined with the anti-slip textures, allows operators to manually lock / unlock the bolt. Installation or adjustment does not require tools such as wrenches, and can be completed by a single person. Compared to traditional bolt fixing structures, this significantly improves operational efficiency.

[0045] Furthermore, the guide groove is provided with a lubricating coating 106, which is made of polytetrafluoroethylene and has a thickness of 0.3-0.8 mm. This component securely secures the cable, resisting accidental pulling forces (such as accidental contact by personnel or minor vehicle scratches), preventing the charging gun from detaching from the charging station due to pulling, and mitigating the risk of damage to the charging gun or electric shock and short circuits caused by detachment, thus improving the safety of the charging scenario.

[0046] Furthermore, the mounting base 1 has mounting ears 103 on both sides, and mounting ears 103 have mounting holes 104 with internal threads. There are reinforcing ribs between the mounting ears 103 and the mounting base 1. The reinforcing ribs are triangular in structure and there are two reinforcing ribs, which are symmetrically distributed on both sides of the mounting ears 103.

[0047] The adjustable bracket 2 has positioning holes 203 on its side wall. The positioning holes 203 are spaced apart along the sliding direction of the adjustable bracket 2. When the locking bolt 401 is tightened against the adjustable bracket 2, its end is embedded in the corresponding positioning hole 203. (The triangular reinforcing rib enhances the load-bearing capacity of the mounting ear 103, which can be adapted to external supports with different load-bearing requirements (such as light wall supports and heavy ground supports); the internal thread mounting hole 104 is compatible with standard bolts, eliminating the need for customized special installation accessories.)

[0048] The adjustable bracket 2 slides horizontally along the adjustment groove 101, which can flexibly adjust the position of the cable fixing point according to different scenarios such as the installation location of the charging pile, the cable length, and the user's operating habits. It can adapt to charging gun cables of different specifications and different installation environments, solve the problem of "fixed position and poor adaptability" of traditional fixing components, and reduce the restrictions on the installation environment.

[0049] The fixed base 1 and the limit block are integrally formed, and the knob 403 and the locking bolt 401 are integrally formed, which reduces the number of parts splicing, reduces production assembly errors, and facilitates industrial mass production; each part has a simple structure (such as arc-shaped receiving cavity and spaced positioning hole 203), does not require complex processing technology, can control production costs, and is suitable for large-scale promotion and application.

[0050] Furthermore, the bottom of the adjustment groove 101 of the fixed base 1 is provided with a drain hole 105, which is spaced along the length of the adjustment groove 101, and the diameter of the drain hole 105 is 3-5mm.

[0051] The drainage holes 105 (3-5mm in diameter, spaced along the length of the adjustment groove 101) at the bottom of the fixed base 1 adjustment groove 101 can drain the accumulated water (such as rainwater or cleaning water) in the adjustment groove 101 in a timely manner, preventing the accumulation of water from breeding dirt and rust in the adjustment groove 101, and avoiding the sliding structure from jamming or the parts from corroding.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
