Description

Technical Field

[0001] This utility model relates to the field of cable positioning technology, specifically a flexible and expandable cable positioning device for new energy vehicles. Background Technology

[0002] New energy vehicles contain multiple wiring harnesses that connect various electrical and electronic systems, such as the power battery, motor controller, and charging system. These harnesses run through the vehicle body, forming a complex structure similar to the human vascular network.

[0003] To prevent short circuits and arcing in automotive wiring harnesses, the harnesses are typically arranged in a reasonable manner and secured using wiring locators. These locators precisely fix the harnesses in preset positions, ensuring sufficient electrical clearance and creepage distance between each other and between the harnesses and the metal parts of the vehicle body. This provides high-voltage safety and physical protection, enabling the vehicle to operate normally.

[0004] Currently, traditional wiring harness locators can only fix the wiring harness. During vehicle operation, vehicle vibration will cause the two ends of the internal wiring harness to be pulled. At this time, the pulling force on the wiring harness will simultaneously cause the wiring harness locator to sway from side to side, thereby reducing the installation stability of the wiring harness locator. Over time, the position and direction of the wiring harness will change, and the wiring harness may even become loose. In this case, the wiring harness will come into contact with the metal parts of the vehicle body, which will reduce the safety of vehicle use. Utility Model Content

[0005] The purpose of this invention is to provide a flexible and expandable cable routing positioner for new energy vehicles to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A flexible and expandable cable routing positioner for new energy vehicles, comprising:

[0008] A base, on which a rotating cover is rotatably mounted, and at both ends of the base and the rotating cover, a lower base plate and an upper cover plate are respectively slidably disposed;

[0009] The lower base plate is rotatably connected to the upper cover plate, and the lower base plate is provided with a limiting component, while the upper cover plate is provided with a positioning component. The limiting component cooperates with the upper cover plate to fix the cable body to the upper cover plate and the lower base plate.

[0010] The base is also provided with a relaxation component. The cable body passes through the relaxation component and is fixed in the limiting member. The two sets of lower base plates are elastically connected to the base through elastic members. When one end of the cable body is pulled, due to the cooperation between the relaxation component, the limiting member and the positioning member, the lower base plate and the upper cover plate at the pulled end move toward the outside of the base.

[0011] The flexible and expandable cable routing positioner for new energy vehicles as described above: the limiting component includes a first positioning plate fixedly mounted on the lower base plate, and the first positioning plate has a positioning groove.

[0012] The flexible and expandable cable routing positioner for new energy vehicles as described above: the positioning component includes a second positioning plate fixedly mounted on the upper cover plate, the second positioning plate having a pressing groove that mates with the positioning groove, and a rubber gasket fixedly mounted on the inner wall of the pressing groove.

[0013] The flexible and expandable cable routing positioner for new energy vehicles as described above: the elastic element includes a first spring disposed in the base, one end of the first spring abutting against the lower base plate, and the other end abutting against a fixed plate fixedly disposed in the base.

[0014] The flexible and expandable cable positioning device for new energy vehicles as described above: the relaxation component includes a limiting structure and a clearance structure. The limiting structure includes a first limiting roller and a second limiting roller rotatably mounted on the base. The first limiting roller and the second limiting roller are symmetrically arranged along the length direction of the base.

[0015] The flexible and expandable cable routing positioner for new energy vehicles as described above: the clearance structure includes a slide rod fixedly mounted on the base, a sleeve slidably mounted on the slide rod, a wire roller rotatably mounted on the sleeve, the wire roller being positioned between the first limiting roller and the second limiting roller, and a second spring also being provided on the slide rod, one end of the second spring abutting against the base and the other end abutting against the sleeve.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By setting limiters and positioning components, and utilizing the guide arc surface on the limiters, operators can quickly and securely connect the cable body to the upper cover, lower base plate, base, and rotating cover. At the same time, the rubber pads inside the positioning components can increase the friction between the cable body and the positioning components, making the connection between the cable body and the upper cover plate more secure and preventing the cable body from shaking and rubbing relative to the upper cover plate and lower base plate.

[0018] Meanwhile, by incorporating a slack assembly, when the cable is pulled due to vibration or other unknown factors during vehicle operation, the slack assembly allows the upper cover and lower base plate to slide simultaneously with the cable body, thereby buffering the pull on the cable body and extending its service life. In the initial state, the cooperation between the second spring and the cable roller ensures that the cable body maintains its maximum curl within the base, allowing it to automatically adjust its length according to changes in external factors during vehicle operation. This reduces the space occupied by the cable body, making the wiring more compact and economical. While ensuring the cable body is fixed in its routing, a certain amount of flexibility is reserved to reduce frictional damage to the cable body caused by pulling. Attached Figure Description

[0027] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0028] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0029] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0030] Please see Figures 1-7 In this embodiment of the utility model, a flexible and expandable cable routing positioner for new energy vehicles includes:

[0031] A base 4, on which a rotating cover 1 is rotatably mounted, and a lower base plate 5 and an upper cover plate 2 are slidably disposed at both ends of the base 4 and the rotating cover 1, respectively.

[0032] Specifically, please refer to Figure 4 T-shaped blocks 201 are fixedly installed on both the lower base plate 5 and the upper cover plate 2. The two sets of T-shaped blocks 201 are slidably installed in the T-shaped grooves opened on the base 4 and the rotating cover 1, respectively. With the cooperation of the T-shaped blocks 201 and the T-shaped grooves, the lower base plate 5 and the upper cover plate 2 will not fall off from the base 4 and the rotating cover 1.

[0033] In particular, please see Figures 1-6 An extension plate 401 is fixedly installed on the base 4. The extension plate 401 can undergo a certain degree of elastic deformation, and a limit block 402 is fixedly installed on the inner side wall of the extension plate 401. During the process of opening or closing the upper cover plate 2, the rotating cover 1 can contact and squeeze with the limit block 402, causing the extension plate 401 to undergo a certain deformation and then reset, thereby realizing the elastic locking between the base 4 and the rotating cover 1, and at the same time driving the upper cover plate 2 to separate from the lower base plate 5 so that the operator can fix the cable body 3 on the base 4.

[0034] The lower base plate 5 is rotatably connected to the upper cover plate 2, and the lower base plate 5 is provided with a limiting component, and the upper cover plate 2 is provided with a positioning component. The limiting component cooperates with the upper cover plate 2 to fix the cable body 3 to the upper cover plate 2 and the lower base plate 5.

[0035] The limiting component includes a first positioning plate 6 fixedly mounted on the lower base plate 5. The first positioning plate 6 has a positioning groove 601. Specifically, please refer to... Figure 2 , Figure 4 The positioning groove 601 is provided with a guide surface 602 on the side facing the opening end of the lower base plate 5. The guide surface 602 can facilitate the operator to press the cable body 3 into the first positioning plate 6, thereby realizing the fixed connection between the cable body 3 and the lower base plate 5.

[0036] The positioning component includes a second positioning plate 7 fixedly mounted on the upper cover plate 2. The second positioning plate 7 has a pressing groove 8 that cooperates with the positioning groove 601. A rubber gasket 801 is fixedly mounted on the inner wall of the pressing groove 8.

[0037] In summary, after the cable body 3 is pressed into the first positioning plate 6, the upper cover 2 is closed. The two sets of upper cover plates 2 and rotating cover 1 move synchronously to make the second positioning plate 7 fit with the first positioning plate 6. Then, the pressing groove 8 and the positioning groove 601 cooperate to fix the cable body 3 between the upper cover 2 and the lower base plate 5. At the same time, the rubber gasket 801 in the pressing groove 8 can directly press the cable body 3, thereby increasing the friction between the cable body 3 and the second positioning plate 7, so that the connection between the cable body 3 and the upper cover 2 and the lower base plate 5 is more secure, preventing the cable body 3 from shaking between the upper cover 2 and the lower base plate 5, avoiding friction between the cable body 3 and the upper cover 2 and the lower base plate 5, thereby improving the service life of the cable body 3.

[0038] Further, please refer to Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The base 4 is also provided with a relaxation component. The cable body 3 passes through the relaxation component and is fixed in the limiting member. The two sets of lower base plates 5 are elastically connected to the base 4 through elastic members. When one end of the cable body 3 is pulled, due to the cooperation between the relaxation component, the limiting member and the positioning member, the lower base plate 5 and the upper cover plate 2 at the pulled end move towards the outside of the base 4.

[0039] The elastic element includes a first spring 9 disposed in the base 4, one end of the first spring 9 abutting against the lower base plate 5, and the other end abutting against the fixed plate 10 fixedly disposed in the base 4;

[0040] For details, please refer to Figure 3Two sets of the first springs 9 are symmetrically arranged along the length of the base 4. Both sets of first springs 9 are in a stretched state. In the initial state, the stretched first springs 9 can drive the two sets of lower base plates 5 to retract the two sets of upper cover plates 2 into the interior of the base 4. At this time, the overall length formed by the two sets of lower base plates 5 and the base 4 is the shortest. After the operator fixes the base 4 in a suitable position, the cable body 3 can be positioned for routing.

[0041] The relaxation component includes a limiting structure and a clearance structure. The limiting structure includes a first limiting roller 12 and a second limiting roller 14 rotatably mounted on the base 4. The first limiting roller 12 and the second limiting roller 14 are symmetrically arranged along the length direction of the base 4.

[0042] The clearance structure includes a slide rod 11 fixedly mounted on the base 4, a sleeve 15 slidably mounted on the slide rod 11, a wire roller 13 rotatably mounted on the sleeve 15, the wire roller 13 being positioned between the first limiting roller 12 and the second limiting roller 14, and a second spring 16 also being mounted on the slide rod 11, one end of the second spring 16 abutting against the base 4, and the other end abutting against the sleeve 15;

[0043] Specifically, please refer to Figure 7 The inner wall of the sleeve 15 is provided with two sets of protrusions 1501 at equal intervals along its circumference. The protrusions 1501 are slidably disposed in the grooves 1101 opened on the outer wall of the slide rod 11. With the cooperation of the grooves 1101 and the protrusions 1501, the sleeve 15 can only slide along the axial direction of the slide rod 11.

[0044] In particular, such as Figure 2 , Figure 5 As shown, the cable body 3 is interposed between the first limiting roller 12, the wire roller 13, and the second limiting roller 14, and the second spring 16 is always in a compressed state, pushing the sleeve 15 to tend to move toward the extension plate 401 (see reference). Figure 6 (Description), so that in the initial state, the amount of curling of the cable body 3 within the base 4 is maximized;

[0045] In actual operation of new energy vehicles, the internal cable body 3 may experience pulling and shaking due to external vibrations or other unknown factors. In this embodiment, when the cable body 3 is pulled, due to the firm connection between the cable body 3 and the upper cover plate 2 and the lower base plate 5, the cable body 3 will drive the upper cover plate 2 and the lower base plate 5 to slide relative to the base 4. During this process, the cable body 3 will squeeze the wire roller 13, so that the wire roller 13 and the sleeve 15 gradually move away from the extension plate 401 along the axial direction of the slide rod 11. When the vibration or other unknown factors disappear, the first spring 9 and the second spring 16 will reset, which can force the cable body 3 to drive the upper cover plate 2 and the lower base plate 5 to reset. Compared with the traditional locator, the above dynamic process can ensure the fixed routing of the cable body 3 while reserving a certain flexibility margin for the cable body 3, reducing the pulling damage to the cable body 3 during vehicle operation. In addition, during the wiring process, it can effectively reduce the space utilization and the amount of cable body 3 used, making the wiring of the cable body 3 more economical and practical.
