Description

Technical Field

[0001] This application relates to the field of cable fixing technology, and in particular to a cable fixing structure and charging device. Background Technology

[0002] The charging gun cable of commercially available charging piles serves as the communication cable connecting the charging pile to the power source of the new energy vehicle. Depending on the charging pile's power, different cable diameters are often used. The cable is led out from inside the charging pile and fixed to the charging pile housing using flange fasteners for vehicle charging.

[0003] The charging pile cable is typically routed out from the top or middle of the side or back of the cabinet to minimize wear and dirt buildup caused by the cable dragging on the ground. Figure 1 As shown, due to the downward sag of the cable itself, in order to reduce the local bending stress at the cable outlet, the cable outlet direction is diagonally downward, forming an acute angle with the cabinet.

[0004] In the traditional sloping design, the cabinet is machined with an inclined flange, and the cable fixing structure is fixed on the flange. If the diameter of the cable is changed, the flange fastener needs to be replaced to install cables of other diameters, resulting in a variety of materials and complicated assembly. Utility Model Content

[0005] The main purpose of this application is to provide a cable fixing structure and charging device, which aims to solve the problem that changing the diameter of the gun wire in the traditional inclined plane solution requires replacing the flange fixing parts, which is cumbersome to assemble.

[0006] To achieve the above objectives, this application provides a cable fixing structure for fixing cables. The cable fixing structure includes a mounting plate, a mounting base, and a fixing plate. The mounting plate has a through hole. The mounting base is connected to one side of the mounting plate and has a wire-passing channel communicating with the through hole. The end of the wire-passing channel away from the through hole is an outlet end. The axial direction of the outlet end forms an acute angle with the mounting plate, and the cable passes through the outlet end. The fixing plate is disposed at the outlet end and is movably connected to the mounting base. The fixing plate has a degree of freedom to move along a first direction to cooperate with the mounting base to clamp the cable. The first direction intersects the axial direction of the outlet end.

[0007] Optionally, the mounting base includes a mounting ring, a ring shell, and a support shell. The mounting ring is connected to the mounting plate and surrounds the outer periphery of the through hole. The ring shell is connected to the inner periphery of the mounting ring and forms the wire passage. The support shell is connected to the inner periphery of the mounting ring and is located at the outlet end. The support shell and the fixing piece are opposite to each other in the first direction to clamp the cable.

[0008] Optionally, both the ring shell and the support shell are sealed to the inner circumference of the mounting ring, so that the inner circumference of the mounting ring is connected to both sides of the mounting ring only through the threading channel.

[0009] Optionally, the support shell has an arc-shaped groove on the side facing the fixing plate; the fixing plate has an arc-shaped bend away from the support shell, and the two ends of the fixing plate are connected to the support shell by a first screw, the extension direction of the first screw is the same as the first direction, and the cable passes through the arc-shaped groove and the arc-shaped bend.

[0010] Optionally, the cable fixing structure further includes a sealing ring, which is disposed at the outlet end and between the arc-shaped groove and the arc-shaped bend, and the cable is disposed on the inner circumference of the sealing ring.

[0011] Optionally, the arc-shaped groove is provided with a plurality of anti-slip grooves spaced apart axially at the outlet end, the anti-slip grooves extending circumferentially along the arc-shaped groove.

[0012] Optionally, the outlet end has an inward-facing first flange structure; the end of the sealing ring near the through hole has an outward-facing second flange structure, and the outer periphery of the second flange structure is provided with a snap-fit ​​groove, into which the first flange structure snaps into the snap-fit ​​groove.

[0013] Optionally, the cable fixing structure further includes a sealing ring disposed between the mounting ring and the mounting plate; wherein the mounting ring is connected to the mounting plate by a second screw.

[0014] Optionally, the end of the annular shell away from the outlet end is a protruding end, which is inserted into the through hole and fits against the inner circumference of the through hole.

[0015] In addition, to achieve the above objectives, this application embodiment also provides a charging device, which includes a housing and the aforementioned cable fixing structure, wherein the mounting plate in the cable fixing structure is part of the housing.

[0016] The cable fixing structure proposed in this application embodiment uses a mounting plate as part of the charging pile housing. The cable is the charging pile gun cable. The cable is passed through the through hole and the cable passage. The fixing plate is moved along the first direction to bring the fixing plate close to the mounting base, thereby clamping the cable between the mounting base and the fixing plate to fix cables of different sizes.

[0032] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

Figure 1 ; Figure 7 The usage state of a cable fixing structure provided in the embodiments of this application. Figure 2 .

[0034] refer to Figures 1 to 7 It should be understood that Figure 4 The connections between the various components should be like Figure 2 As compact as in the middle, this is only for illustrative purposes and will Figure 4 The components are shown disassembled for easier understanding. This application provides a cable fixing structure for fixing cable 1. The cable fixing structure may include a mounting plate 2, a mounting base 3, and a fixing piece 4. The mounting plate 2 has a through hole 21. The mounting base 3 is connected to one side of the mounting plate 2 and has a wire-passing channel communicating with the through hole 21. The end of the wire-passing channel away from the through hole 21 is the outlet end. The axial direction of the outlet end makes an acute angle with the mounting plate 2. Cable 1 passes through the outlet end. The fixing piece 4 is disposed at the outlet end and is movably connected to the mounting base 3. The fixing piece 4 has a degree of freedom to move along a first direction to cooperate with the mounting base 3 to clamp cable 1. The first direction intersects with the axial direction of the outlet end.

[0035] The cable fixing structure proposed in this application embodiment uses the mounting plate 2 as part of the charging pile housing, and the cable 1 is the cable 1 of the charging pile gun wire. The cable 1 is passed through the through hole 21 and the wire passage, and the fixing plate 4 is moved along the first direction to bring the fixing plate 4 close to the mounting base 3. The cable 1 can be clamped between the mounting base 3 and the fixing plate 4 to fix cables 1 of different sizes. At the same time, the angle between the cable 1 and the mounting plate 2 is an acute angle, that is, the cable 1 is set at an angle. In this way, the cable 1 can pass through the two sides of the mounting plate 2 at an angle, and the cable fixing structure can fix cables 1 of different sizes.

[0036] Among them, such as Figure 2 As shown, the first direction is the X direction, and cable 1 refers to the structure that needs to pass through both sides of the plate in an inclined manner and be fixed in position. The above description of mounting plate 2 as part of the charging pile housing and cable 1 as the charging pile gun cable are all exemplary descriptions. The cable fixing structure in this application is not limited to fixing cable 1. Any strip-shaped structure that needs to pass through the plate in an inclined manner can be fixed using the cable fixing structure in this application.

[0037] It should be understood that the section through which cable 1 passes through mounting plate 2 is referred to as the first section. The inclination mentioned above is a relative concept. In this application, inclination refers to the angle between the extension direction of the first section and the mounting plate 2 being an acute angle, not that cable 1 is inclined relative to the horizontal plane.

[0038] For example, such as Figure 6 As shown, if the mounting plate 2 is considered to be vertically set at this time, that is, the mounting plate 2 is parallel to the direction of gravity, then the angle between the extension direction of the first section and the direction of gravity is an acute angle. If the angle between the mounting plate 2 itself and the direction of gravity is an acute angle, then even if the extension direction of the first section is the same as the direction of gravity, it will be regarded as the first section being tilted relative to the mounting plate 2.

[0039] Specifically, the angle between the extension direction of the first section and the mounting plate 2 is denoted as a, where 0° < a < 90°. a can be 30°, 40°, 50°, 60°, etc. The specific value of a can be selected according to actual needs.

[0040] It should be noted that, in the above content, if the mounting plate 2 is used as part of the charging pile housing, the mounting base 3 should be located on the inside of the charging pile housing. This helps to keep the outside of the charging pile housing clean and also protects the mounting base 3 and the fixing plate 4 from easy damage.

[0041] Furthermore, the fixing plate 4 moves along the first direction to cooperate with the mounting base 3 to clamp the cable 1. The first direction can be perpendicular to the extension direction of the first section, which makes it easier to clamp the cable 1 and the clamping effect is better.

[0042] refer to Figure 4 In an exemplary embodiment, the mounting base 3 may include a mounting ring 31, a ring shell 32, and a support shell 33. The mounting ring 31 is connected to the mounting plate 2 and is disposed around the outer periphery of the through hole 21. The ring shell 32 is connected to the inner periphery of the mounting ring 31 and forms a wire passage. The support shell 33 is connected to the inner periphery of the mounting ring 31 and is located at the outlet end. The support shell 33 is opposite to the fixing piece 4 in a first direction to clamp the cable 1.

[0043] The mounting base 3 mainly includes three parts: a mounting ring 31 located on the periphery, and a ring shell 32 and a support shell 33 connected to the inner circumference of the mounting ring 31. The ring shell 32 is cylindrical and forms the above-mentioned wire passage. The support shell 33 is located at the outlet end of the wire passage. The fixing piece 4 and the support shell 33 on the mounting base 3 cooperate to clamp the cable 1.

[0044] refer to Figure 4 In an exemplary embodiment, both the ring shell 32 and the support shell 33 are sealed to the inner circumference of the mounting ring 31, so that the inner circumference of the mounting ring 31 is connected to both sides of the mounting ring 31 only through the wire channel.

[0045] Specifically, the ring shell 32 and the support shell 33 are sealed to the inner circumference of the mounting ring 31, so that the three parts of the mounting base 3 form a whole, which makes it easy for the mounting base 3 to be integrally formed by casting. At the same time, it plays a certain role in waterproofing, preventing water from flowing from one side of the mounting plate 2 through the gap between the ring shell 32, the support shell 33 and the mounting ring 31 to the other side of the mounting plate 2 in rainy weather.

[0046] refer to Figure 4 In an exemplary embodiment, the support shell 33 has an arc-shaped groove on the side facing the fixing piece 4; the fixing piece 4 has an arc-shaped bend away from the support shell 33, and the two ends of the fixing piece 4 are connected to the support shell 33 by a first screw, the extension direction of the first screw is the same as the first direction, and the cable 1 passes through the arc-shaped groove and the arc-shaped bend.

[0047] In this embodiment, the support shell 33 is provided with an arc-shaped groove, and the fixing piece 4 is provided with an arc-shaped bend to facilitate clamping the cable 1. If the workpiece to be fixed is not the columnar cable 1, but other components with a prismatic structure, the arc-shaped groove and the arc-shaped bend can be modified accordingly to fit a part of the workpiece to be fixed so as to facilitate clamping the workpiece.

[0048] Furthermore, the two ends of the fixing plate 4 are connected to the support shell 33 by the first screw. Threaded holes can be provided on the support shell 33, and insertion holes can be provided on both ends of the fixing plate 4. The first screw can be passed through the insertion hole and screwed into the threaded hole. When the first screw is tightened, the fixing plate 4 can be moved closer to the support shell 33 in the first direction, thereby clamping the cable 1.

[0049] refer to Figure 1 , Figure 4 and Figure 6 In an exemplary embodiment, the cable fixing structure may further include a sealing ring 5, which is disposed at the outlet end and between the arc-shaped groove and the arc-shaped bend, and the cable 1 is disposed on the inner circumference of the sealing ring 5.

[0050] Specifically, the sealing ring 5 is inserted at the outlet end and between the arc-shaped groove and the arc-shaped bend, and the cable 1 is inserted through the inner circumference of the sealing ring 5. In this way, the sealing ring 5 can effectively seal the outlet end of the cable channel, thereby preventing moisture from reaching the other side of the mounting plate 2 from one side through the outlet end of the cable channel.

[0051] It should be understood that at this time, the fixing plate 4 and the support shell 33 press the sealing ring 5 in the first direction, and further press the cable 1 through the sealing ring 5 to clamp the cable 1.

[0052] refer to Figure 4 In an exemplary embodiment, a plurality of anti-slip grooves 331 are provided on the arc-shaped groove and are spaced apart axially at the outlet end. The anti-slip grooves 331 extend circumferentially along the arc-shaped groove.

[0053] Specifically, the anti-slip groove 331 can effectively increase the friction between the cable 1 and the support shell 33, thereby enhancing the fixing effect.

[0054] Furthermore, if the above-mentioned solution of adding a sealing ring 5 is adopted, the anti-slip groove 331 can effectively increase the friction between the sealing ring 5 and the support shell 33, preventing the cable 1 from moving the sealing ring 5 during long-term use, ensuring that the sealing ring 5 will not easily detach from the outlet end of the cable channel, and further ensuring the waterproof effect.

[0055] refer to Figure 4 In an exemplary embodiment, the outlet end has an inwardly facing first flange structure 321; the end of the sealing ring 5 near the through hole 21 has an outwardly facing second flange structure 51, and the outer periphery of the second flange structure 51 is provided with a snap-fit ​​groove 511, and the first flange structure 321 snaps into the snap-fit ​​groove 511.

[0056] Specifically, after the first flange structure 321 is inserted into the slot 511 on the second flange structure 51, the position of the sealing ring 5 is fixed, which can further enhance the sealing effect and prevent moisture from passing through the outlet end of the wire channel. At the same time, the position of the sealing ring 5 can be fixed, so when installing the sealing ring 5, there is no need to specifically control the position of the sealing ring 5. Just ensure that the first flange structure 321 is inserted into the slot 511 on the second flange structure 51, making the operation more convenient.

[0057] refer to Figure 4 In an exemplary embodiment, the cable fixing structure may further include a sealing ring 6, which is disposed between the mounting ring 31 and the mounting plate 2; wherein the mounting ring 31 is connected to the mounting plate 2 by a second screw.

[0058] The sealing ring 6 effectively seals the gap between the mounting ring 31 and the mounting plate 2, improving the waterproof effect.

[0059] Furthermore, the mounting ring 31 is connected to the mounting plate 2 by a second screw. The second screw can be a press-fit rivet, which is pressed onto the mounting plate 2 so that the screw portion of the second screw is located on the side of the mounting plate 2 facing the mounting ring 31. In this way, the side of the mounting plate 2 away from the mounting ring 31 is flat, and when the mounting plate 2 is used as part of the charging pile housing, the outer side of the charging pile housing is more aesthetically pleasing. Moreover, since the second screws are all located inside the housing, they will hardly cause scratches to the appearance of the charging pile housing during the assembly process. In contrast, in the traditional beveled design, the flange fixing screws are arranged around the gun wire, which is not easy to fix and is easy to scratch the appearance of the equipment.

[0060] Specifically, the mounting ring 31 has a corresponding mounting hole, through which the second screw passes and the nut is tightened on the second screw. The mounting ring 31 is clamped and fixed to the sealing ring 5 by the cooperation of the nut and the second screw.

[0061] It should be understood that, as Figure 4 As shown, the sealing ring 6 is located between the mounting ring 31 and the mounting plate 2, and the sealing ring 6 is also provided with a hole for the second screw to pass through.

[0062] refer to Figure 5 In an exemplary embodiment, the end of the annular shell 32 away from the outlet end is a protruding end 322, which is inserted into the through hole 21 and fits against the inner circumference of the through hole 21.

[0063] Specifically, the protruding end 322 is inserted into the through hole 21 and fits against the inner circumference of the through hole 21. This makes the connection between the wire passage and the through hole 21 more tight, and the fit between the protruding end 322 and the inner circumference of the through hole 21 makes it more difficult for external debris to pass through the gap between the protruding end 322 and the through hole 21.

[0064] Taking a charging pile as an example, during installation, the mounting plate 2 is part of the charging pile housing, and the cable 1 is the charging pile gun cable. First, the sealing ring 5 can be snapped into the outlet end of the mounting base 3, and then the cable 1 can be passed through the sealing ring 5 and the through hole 21 on the housing. The sealing ring 5 and the mounting base 3 are connected to the through hole 21 of the housing by the second screw. Then, the fixing plate 4 and the mounting base 3 are connected by the first screw, so that the fixing plate 4 and the mounting base 3 can squeeze and fix the cable 1, which is convenient and quick.

[0065] Traditional inclined cable exit schemes require extensive welding processes to assemble the inclined parts with the housing, and finally, flange fasteners are installed on the inclined surface to secure the cable. This forming method is prone to component deformation due to welding, leading to water leakage and high welding costs. Compared with traditional inclined cable exit schemes, this application saves a lot of welding time, avoids other effects caused by welding, reduces costs, and has high overall structure installation and disassembly efficiency, making maintenance more convenient.

[0066] Based on the above embodiments, this application also provides a charging device, which may include a housing and the above-mentioned cable fixing structure, wherein the mounting plate 2 in the cable fixing structure is part of the housing.

[0067] The charging equipment can be a charging pile or other charging devices, such as... Figure 1 As shown, the cable outlet area of ​​a traditional charging pile is mostly located on the side wall of the housing near the top. Therefore, the mounting plate 2 in the above-mentioned cable fixing structure can be part of the side wall of the housing, and the mounting base 3 is located inside the housing.

[0068] Specifically, if the angle between cable 1 and the side wall of the housing is acute, then the height of the part of cable 1 inside the housing should be greater than the height of the part of cable 1 outside the housing. This makes the cable 1 exit more smoothly, and the space occupied by the cable 1 exiting the housing is smaller on the outside of the housing.

[0069] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
