Description

Technical Field

[0001] This utility model relates to the field of charging cable tray technology for new energy vehicles, specifically to a cable tray structure with heat insulation protection. Background Technology

[0002] Against the backdrop of the rapid development of the new energy vehicle industry, charging piles, as core supporting facilities, directly affect vehicle charging efficiency and safety through their stable operation. The internal and external wiring of charging piles requires a large number of cable harnesses, which undertake critical functions such as current transmission and signal control. Cable trays, as the core component supporting and protecting the charging pile cable harnesses, have performance requirements far exceeding those of ordinary cable tray equipment.

[0003] Most outdoor charging piles have their wiring harnesses installed on the wall or ground. However, in the hot summer months, the temperature of the wall or ground is high, especially in July and August, when it can reach over 50°C. Since the wiring harness is installed on the wall or ground, the heat from the wall or ground will be conducted to the wiring harness, causing the charging pile wiring harness inside to also be in a high-heat state.

[0004] For example, the cable tray disclosed in Chinese utility model patent CN215378329U is a cable tray that facilitates the classification and arrangement of wire harnesses. Although this cable tray facilitates the organization of wire harnesses, it is difficult to provide heat insulation protection for the wire harnesses inside when the cable tray is used outdoors.

[0005] For example, the cable tray disclosed in Chinese utility model patent CN215920207U is a cable tray that facilitates the fixing of wire harnesses. Although the cable tray can fix a large number of wire harnesses, it is also difficult to provide heat insulation protection for the wire harnesses inside when the cable tray is used outdoors.

[0006] Based on this, a wire harness tray structure with thermal insulation protection is proposed. Utility Model Content

[0031] This utility model provides a heat-insulated cable tray structure to solve the problem that in hot summer weather, when the temperature of the wall or ground is high, the heat from the wall or ground will be conducted to the cable tray, causing the charging pile cable tray inside to also be in a high-heat state. The specific technical solution is as follows: Example

[0032] like Figures 1-8 As shown in the figure, the present invention provides a heat-insulated and protected wire harness cable tray structure, comprising: The U-shaped bracket 10 has an extension 101 at both ends; Top sealing plate 20, which is mounted on two outer extensions 101; Four sets of quick-release locking structures, two of which are installed between one of the extensions 101 and the top sealing plate 20, and the other two are installed between the other extension 101 and the top sealing plate 20. The heat insulation horizontal plate 40 is fixedly installed in the lower part of the inner cavity of the U-shaped bracket 10, and after installation, a heat insulation cavity 50 is formed between the heat insulation horizontal plate 40 and the bottom of the inner cavity of the U-shaped bracket 10. The wiring harness of the charging pile can be placed sequentially on the heat insulation horizontal plate 40; The wire harness clamp 60 is movably installed on the upper part of the inner cavity of the U-shaped bracket 10; The adjustment component has one end installed on the top sealing plate 20 and the other end connected to the heat insulation horizontal plate 40; The adjustment component allows the wire harness clamp 60 to move upward or downward in the upper part of the inner cavity of the U-shaped bracket 10. When moving downward, it fixes the wire harness placed on the heat insulation plate 40. The heat-insulating base plate 120 is adhesively fixed to the bottom of the U-shaped bracket 10; and Four Z-shaped fixing feet 130, two of which are fixedly installed at the two ends of the bottom of one side wall of the U-shaped bracket 10, and the other two Z-shaped fixing feet 130 are fixedly installed at the two ends of the bottom of the other side wall of the U-shaped bracket 10. Each Z-shaped fixed support leg 130 is provided with a countersunk hole 1301.

[0033] In this embodiment, the charging pile's wiring harness is placed on the heat-insulating horizontal plate 40. The wiring harness clamp 60 is moved downward by the adjustment component, thereby fixing the wiring harness on the heat-insulating horizontal plate 40. The heat-insulating cavity 50 formed by the heat-insulating horizontal plate 40 and the bottom of the U-shaped bracket 10, as well as the heat-insulating base plate 120 at the bottom of the U-shaped bracket 10, blocks the heat conducted by the wall or ground, preventing the wiring harness from being in a high-heat state. The wiring harness bridge structure can be fixedly installed on the wall or ground next to the outdoor charging pile through the countersunk holes 1301 on the four Z-shaped fixing feet 130. The top sealing plate 20 is installed and fixed to the outer extension 101 of the U-shaped bracket 10 through four sets of quick-release locking structures, which plays a role in sealing and protection. Example

[0034] like Figures 1-8 As shown, the improvements are based on Example 1: Furthermore, each quick-release locking structure includes a lower slot 102 opened at the edge of the side wall of the extension portion 101 and an upper slot 202 opened at the edge of the side wall of the top sealing plate 20 corresponding to the lower slot 102. Each quick-release locking structure also includes a U-shaped locking seat 30, each U-shaped locking seat 30 having two locking tongues 301. The two locking tongues 301 can be inserted into the corresponding lower slot 102 and upper slot 202 respectively, and after insertion, lock the top sealing plate 20 and U-shaped bracket 10 together.

[0035] In this embodiment, the two locking tongues 301 of the U-shaped locking seat 30 are respectively inserted into the corresponding lower slot 102 and upper slot 202, thereby locking and fixing the top sealing plate 20 and the U-shaped bracket 10.

[0036] Furthermore, by pulling out the four U-shaped locking seats 30 in sequence, the top sealing plate 20 and the U-shaped bracket 10 can be quickly disassembled, thus solving the technical problem of time-consuming disassembly of traditional bolt fixing.

[0037] Furthermore, each quick-release locking structure also includes a loop pull head 302. Each loop pull head 302 is fixedly installed on the outer side wall of the corresponding U-shaped locking seat 30. Specifically, when disassembling the four U-shaped locking seats 30 in sequence, the corresponding loop pull head 302 can be hooked by the hook (not shown in the figure) and pulled outward to disassemble the corresponding U-shaped locking seat 30.

[0038] In this embodiment, when disassembling the U-shaped locking seat 30, the corresponding U-shaped locking seat 30 can be disassembled by hooking the loop pull head 302 with a hook and pulling it outward.

[0039] Furthermore, the shapes and sizes of the two latches 301 are matched with the shapes and sizes of the corresponding lower slot 102 and upper slot 202, respectively.

[0040] In this embodiment, the shape and size of the two locking tongues 301 are matched with the shape and size of the corresponding lower slot 102 and upper slot 202, respectively, to ensure the stability of the insertion and locking.

[0041] Furthermore, the heat insulation plate 40 has several heat dissipation holes 401.

[0042] In this embodiment, the heat dissipation holes 401 on the heat insulation plate 40 can promote air circulation around the wire harness and assist in heat dissipation.

[0043] Furthermore, several heat dissipation side holes 140 are provided on the upper part of the two side walls of the U-shaped bracket 10 and at the corresponding heat insulation horizontal plate 40. Both sets of heat dissipation side holes 140 are connected to the upper part of the inner cavity of the U-shaped bracket 10.

[0044] In this embodiment, several heat dissipation side holes 140 on the upper part of the side walls on both sides of the U-shaped bracket 10 are connected to the upper part of the inner cavity to further enhance air circulation and help dissipate heat.

[0045] Furthermore, the lower surface of the wire harness clamp 60 is provided with a plurality of arc-shaped clamping grooves 601, and the spacing between adjacent arc-shaped clamping grooves 601 is equal. Each arc-shaped groove 601 is used to constrain and fix the wire harness placed on the heat insulation cross plate 40.

[0046] In this embodiment, the multiple arc-shaped clamping grooves 601 on the lower surface of the wire harness clamp 60 can constrain and fix the wire harness placed on the heat insulation horizontal plate 40, so that the wire harness is arranged neatly and fixed firmly.

[0047] Furthermore, the adjustment assembly includes a limiting bushing 70 fixedly installed at the center of the upper surface of the wire harness clamp plate 60, a lead screw nut 80 embedded at the center of the upper surface of the top sealing plate 20, a lead screw 90 threaded in the lead screw nut 80, and a handwheel 100 fixedly installed at one end of the top of the lead screw 90. The bottom end of the lead screw 90 is rotatably installed inside the limiting bushing 70.

[0048] In this embodiment, rotating the handwheel 100 drives the lead screw 90 to rotate. The lead screw 90 is driven by the internal thread of the lead screw nut 80, which in turn causes the limiting bushing 70 to drive the wire harness clamp 60 to move up and down. When it moves downward, it fixes the wire harness. Example

[0049] like Figures 1-8 As shown, the improvements are based on Example 2: Furthermore, the adjustment assembly also includes a guide structure, which is installed between the harness clamp 60 and the top sealing plate 20.

[0050] Furthermore, the guide structure includes guide holes 201 opened on both sides of the top sealing plate 20; The guide structure also includes guide rods 110 that are slidably installed in the corresponding guide holes 201, and the bottom ends of the two guide rods 110 are fixedly connected to the upper surface of the wire harness clamp 60.

[0051] In this embodiment, the guide rod 110 slides within the guide hole 201, which guides the up-and-down movement of the wire harness clamp 60 and ensures its smooth movement.

[0052] The different embodiments described above can be combined, substituted, or used in combination with each other.

[0053] Work steps: like Figures 1-8As shown, firstly, the wire harness bridge structure is fixed to the wall or ground next to the outdoor charging pile using the countersunk holes 1301 on the four Z-shaped fixing feet 130. Next, the charging pile's wire harness is placed on the heat-insulating horizontal plate 40. By turning the handwheel 100, the lead screw 90 rotates within the lead screw nut 80, causing the wire harness clamp 60 to move downwards. The arc-shaped clamping groove 601 on the lower surface of the wire harness clamp 60 constrains and fixes the wire harness to the heat-insulating horizontal plate 40. Simultaneously, the guide rod 110 slides within the guide hole 201, ensuring the smooth movement of the wire harness clamp 60. Then, using four sets of quick-release locking structures, the locking tongue 301 of the U-shaped locking seat 30 is inserted into the lower slot 102 and upper slot 202 respectively, locking the top sealing plate 20 to the U-shaped bracket 10, thus sealing and protecting the internal wire harness. During use, the heat insulation cavity 50 formed by the heat insulation horizontal plate 40 and the bottom of the U-shaped bracket 10, as well as the heat insulation base plate 120 at the bottom of the U-shaped bracket 10, can block heat conducted from the wall or ground. The heat dissipation bottom hole 401 on the heat insulation horizontal plate 40 and the heat dissipation side holes 140 on both sides of the U-shaped bracket 10 can promote air circulation, assist in heat dissipation, and prevent the wiring harness from being in a high-heat state. If it is necessary to remove the top sealing plate 20, it can be quickly removed by hooking the U-shaped locking seat 30 outward with the hook using the pull head 302.

[0054] In summary: First, the heat insulation cavity 50 formed by the heat insulation horizontal plate 40 and the bottom of the U-shaped bracket 10, as well as the heat insulation base plate 120 at the bottom of the U-shaped bracket 10, can effectively block the heat conducted by the wall or the ground, prevent the charging pile harness from being in a high-heat state, and ensure the safety and lifespan of the harness.

[0055] The design of the second and fourth quick-release locking structure allows for the rapid installation and disassembly of the top sealing plate 20 and the U-shaped bracket 10. Compared with the traditional bolt fixing method, the operation is more convenient and saves time.

[0056] Third, the design of the U-shaped pull head 302 provides a convenient point of force for disassembling the U-shaped locking seat 30, making the disassembly process easier.

[0057] Fourth, the heat dissipation bottom hole 401 on the heat insulation horizontal plate 40 and the heat dissipation side holes 140 on both sides of the U-shaped bracket 10 enhance internal air circulation, assist in heat dissipation, and further improve the operating environment of the wire harness.

[0058] 5. The arc-shaped clamping groove 601 on the lower surface of the wire harness clamp 60 can neatly constrain and fix multiple wire harnesses, avoid wire harnesses from becoming messy, and at the same time fix them firmly to prevent the wire harnesses from shifting during use.

[0059] VI. The adjustment component, in conjunction with the guide structure, can smoothly and precisely adjust the position of the wire harness clamp 60 to adapt to the fixing needs of different quantities and specifications of wire harnesses, making it highly adaptable.

[0060] 7. The design of four Z-shaped fixing feet 130 and countersunk holes 1301 enables the wire harness cable tray structure to be stably installed on the wall or ground, ensuring a firm and reliable installation.

[0061] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model.
