Description

Technical Field

[0001] This application relates to the field of cable protection technology, and in particular to a gun wire anti-theft device. Background Technology

[0002] With the booming development of the electric vehicle industry, charging piles, as an important infrastructure, have been widely constructed and applied. High-power DC charging piles, in particular, play a crucial role in charging pile operation due to their fast charging advantage, greatly meeting the rapid energy replenishment needs of electric vehicle users, promoting the further popularization of electric vehicles, and facilitating the development of the new energy transportation sector. However, charging piles also face many challenges during operation.

[0003] Currently, in the daily operation of charging stations, the industry has adopted various conventional methods to ensure the normal use and basic protection of charging cables. On the one hand, some charging station operators choose to use ordinary rubber protective sleeves to wrap the cables. These sleeves have a certain degree of flexibility and abrasion resistance, which can prevent the surface of the cables from being scratched to some extent. On the other hand, some companies add plastic protective shells to the outside of the cables. These plastic protective shells are relatively sturdy and can withstand some minor external impacts. In addition, some operators set up simple protective barriers around the cables to reduce the possibility of the cables being hit by external objects.

[0004] However, these conventional methods have significant drawbacks. Ordinary rubber protective sleeves and plastic protective shells have weak shear resistance and are easily cut by deliberate cable cutting. Simple protective barriers can only prevent some accidental collisions and are ineffective in deterring intentional thieves. Widespread deliberate cutting and theft of charging gun cables would cause huge direct economic and operational losses to charging station operators, and existing technologies are insufficient to meet the needs of charging gun cable theft prevention. Utility Model Content

[0005] To improve the anti-theft function of gun cables, this application provides an anti-theft device for gun cables.

[0006] The anti-theft device for the gun wire provided in this application adopts the following technical solution: A gun wire anti-theft device includes a gun wire body, a first end of which is connected to a charging post, and a second end of which is connected to a gun head. The anti-theft device includes: a puncture-resistant layer, which is sleeved on the outer periphery of the gun wire body. The puncture-resistant layer has two sets: a first set of puncture-resistant layers is located at the first end of the gun wire body and extends from the first end of the gun wire body towards the second end of the gun wire body by a first predetermined length; a second set of puncture-resistant layers is located at the second end of the gun wire body and extends from the second end of the gun wire body towards the first end of the gun wire body by a second predetermined length; a braided protective layer, which is sleeved on the outer periphery of the gun wire body, and the puncture-resistant layer is sandwiched between the gun wire body and the braided protective layer; and an insulating layer, which is sleeved on the outer periphery of the braided protective layer.

[0007] By adopting the above technical solution, the anti-stab layer is set on the outer periphery of both ends of the gun wire body and extends to a certain length. The braided protective layer is wrapped around the outer periphery of the gun wire body and sandwiches the anti-stab layer in the middle, which can prevent the shear section of the braided protective layer from piercing into the gun wire and causing damage. The braided protective layer has high shear resistance and corrosion resistance, and plays a major role in anti-theft design. The insulating layer is wrapped around the outer periphery of the braided protective layer, which can play a good role in insulation protection and prevent the risk of voltage leakage of the gun wire. The overall device can improve the shear resistance of the gun wire and play the role of anti-theft of the gun wire.

[0008] Optionally, a positioning element is provided between the gun wire body and the insulating layer.

[0009] By adopting the above technical solution, a positioning component is set between the charging cable body and the insulation layer. The positioning component can locate the position of the charging cable in real time. When the charging cable is stolen, the location of the charging cable can be quickly tracked through positioning, which facilitates the recovery of the stolen charging cable. This further enhances the anti-theft capability of the charging cable anti-theft device and reduces the economic and operational losses of charging pile operators.

[0010] Optionally, the positioning element is located at the second end of the gun wire body.

[0011] By adopting the above technical solution, the positioning component is set at the second end of the charging cable body. Since the second end of the charging cable body is connected to the charging head, which is a part that moves frequently during the charging process and is easily manipulated by thieves, the positioning component set at this location can more efficiently track the position of the charging head and the charging cable. When the charging cable is stolen, the specific location of the charging cable can be obtained in a timely manner through the control terminal connected to the positioning component, thereby effectively reducing the risk of the charging cable being stolen and reducing the economic and operational losses of the charging pile operator.

[0012] Optionally, the positioning element is connected to a control terminal.

[0013] By adopting the above technical solution, the positioning device communicates with the control terminal, and can locate and track the position of the gun cable. When the gun cable moves abnormally or may be stolen, the positioning device can transmit the relevant location information to the control terminal in a timely manner, so that the managers can keep abreast of the status of the gun cable in real time, and take timely measures to further enhance the anti-theft capability of the gun cable.

[0014] Optionally, the stab-resistant layer is stainless steel tape, which is adhered to the gun wire body.

[0015] By adopting the above technical solution, the anti-stab layer is made of stainless steel tape and bonded to the gun wire body. The anti-stab layer at the head and tail of the gun wire can prevent the sheared section of the braided protective layer from piercing into the gun wire and causing damage, thereby improving the safety and stability of the gun wire and enhancing the anti-theft capability of the entire gun wire anti-theft device.

[0016] Optionally, the woven protective layer is a stainless steel woven mesh sleeve.

[0017] By adopting the above technical solutions, the stainless steel woven mesh sleeve has high shear resistance and corrosion resistance, playing a major role in anti-theft design. It can effectively resist theft using tools such as cable cutters, prevent the charging gun wire from being cut and stolen, and its corrosion resistance can ensure long-term use in various environments, maintaining the protection of the charging gun wire and improving the reliability and service life of the entire charging gun wire anti-theft device.

[0018] Optionally, it may also include an auxiliary layer, which is fitted inside the woven protective layer.

[0019] By adopting the above technical solution, the auxiliary layer set inside the braided protective layer can further enhance the protective performance and help improve the shear resistance and anti-theft capability of the gun wire.

[0020] Optionally, the auxiliary layer is made of the same material as the woven protective layer.

[0021] By adopting the above technical solution, the auxiliary layer and the braided protective layer are made of the same material. Both are made of materials with high shear resistance and corrosion resistance. When the auxiliary layer is placed inside the braided protective layer, it can further enhance the overall shear resistance of the charging cable, thereby improving the anti-theft performance of the charging cable. Furthermore, since the materials are the same, the two work together more harmoniously in protecting the charging cable, effectively resisting external shear damage to the charging cable and preventing the charging cable from being stolen. At the same time, the corrosion resistance also helps to extend the service life of the charging cable.

[0022] Optionally, the auxiliary layer includes a wrapping part and protrusions. The wrapping part is fitted inside the woven protective layer, and a plurality of protrusions are provided, with the plurality of protrusions spirally wound around the outer periphery of the wrapping part.

[0023] By adopting the above technical solution, the auxiliary layer is wrapped inside the braided protective layer, which can work together with the braided protective layer to enhance the protection of the charging cable itself; several protrusions are spirally coiled around the outer periphery of the wrapping part. This spiral coiling structure not only increases the overall strength and stability of the auxiliary layer, but also disperses the force when subjected to external force damage such as shearing, further improving the shear resistance of the charging cable, thereby better protecting the charging cable and enhancing the anti-theft capability of the charging cable.

[0024] Optionally, a plurality of connecting portions are provided at intervals between adjacent protrusions along the extending direction of the protrusion.

[0025] By adopting the above technical solution, multiple connecting parts are spaced apart between adjacent protrusions along the extension direction of the protrusions. These connecting parts connect adjacent protrusions, enhancing the overall structural stability and strength of the auxiliary layer, while also optimizing the support performance for the braided protective layer. When the cable is subjected to external force, the connecting parts can disperse stress, preventing the protrusions from detaching or shifting. The spacing of the connecting parts also increases the possibility of clamping with cable cutters, increasing the difficulty of cutting and allowing the auxiliary layer to better cooperate with the braided protective layer, jointly improving the cable's shear resistance and anti-theft performance. Furthermore, the spacing of the connecting parts can save materials and reduce costs to some extent.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The stab-resistant layer prevents the sheared section of the braided protective layer from penetrating the gun wire and causing damage; 2. The braided protective layer has high shear resistance and corrosion resistance, which can improve the anti-theft capability of the gun wire; 3. The insulation layer provides excellent insulation protection and prevents the risk of voltage leakage from the gun wire. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted in a broad sense, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0033] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0034] like Figure 1 As shown in the figure, this application discloses a gun wire anti-theft device (hereinafter referred to as "the device"), which includes a stacked anti-stab layer 1, a braided protective layer 2 and an insulating layer 3.

[0035] The charging cable includes a charging cable body 100, with a first end connected to a charging post and a second end connected to a charging head 200, so as to realize the power connection from the charging post to the charging head 200.

[0036] like Figure 1 As shown, the anti-stab layer 1 is sleeved on the outer periphery of the wire body 100, and there are two sets. The first set of anti-stab layer 1 is located at the first end of the wire body 100, and extends from the first end of the wire body 100 towards the second end of the wire body 100 by a first predetermined length. The second set of anti-stab layer 1 is located at the second end of the wire body 100, and extends from the second end of the wire body 100 towards the first end of the wire body 100 by a second predetermined length. The first predetermined length and the second predetermined length can be the same or different. In this embodiment, both are 100 mm.

[0037] like Figure 1 As shown, the braided protective layer 2 is fitted around the outer periphery of the cable body 100, sandwiching the puncture-resistant layer 1 in the middle. The puncture-resistant layer 1 prevents the sheared section of the braided protective layer 2 from penetrating the cable and causing damage. The braided protective layer 2 has high shear resistance and corrosion resistance, and can withstand damage from cable shears. The insulation layer 3 is fitted around the outer periphery of the braided protective layer 2, and the insulation layer 3 provides excellent insulation protection. This structural design achieves the effect of improving the shear resistance of the cable and preventing voltage leakage.

[0038] Specifically, the stab-resistant layer 1 is stainless steel tape. Stainless steel tape possesses a certain degree of flexibility and strength, and its material, stainless steel, provides good corrosion resistance. During installation, the stainless steel tape is fixed to the wire body 100 using adhesive. It is understood that the stab-resistant layer 1 could also be other metal tapes with stab-resistant properties, such as aluminum alloy tape. The first set of stab-resistant layers 1 extends a certain length from the first end of the wire body 100 towards the second end, and the second set of stab-resistant layers 1 extends a certain length from the second end of the wire body 100 towards the first end. This arrangement provides focused protection for the easily damaged parts at both ends of the wire.

[0039] like Figure 1 As shown, optionally, the braided protective layer 2 is a stainless steel mesh sleeve. Specifically, the braided protective layer 2 is a 316L stainless steel flexible metal hose corrugated mesh sleeve, used to protect the internal gun wire body 100. This mesh sleeve is made of 316L stainless steel, which has high shear resistance and corrosion resistance, and also has good flexibility and strength. During installation, it is fitted around the gun wire body 100 and the puncture-resistant layer 1, effectively resisting external shear damage. Optionally, the braided protective layer 2 can also be other high-strength metal braided mesh sleeves, such as titanium alloy braided mesh sleeves.

[0040] Specifically, insulation layer 3 is a thick-walled, highly flame-retardant heat-shrink tubing. This heat-shrink tubing has high flame retardancy, preventing fires, and also provides 35KV high-voltage insulation. During installation, the heat-shrink tubing is heated to shrink and tightly wrap around the outer perimeter of the braided protective layer 2, providing excellent insulation protection. Insulation layer 3, covering the braided protective layer 2, prevents voltage leakage from the gun line and ensures safe use. Optionally, insulation layer 3 can also be other high-voltage insulating materials, such as rubber insulating sleeves.

[0041] After undergoing shear failure testing, the device can withstand shear failure forces of over 6500N, effectively protecting the charging gun cable and providing anti-theft protection.

[0042] The implementation principle of this embodiment is as follows: by setting an anti-stab layer 1, a braided protective layer 2, and an insulating layer 3, a multi-layered protective structure is formed, which greatly improves the shear resistance and anti-theft capability of the charging cable. The anti-stab layer 1 prevents the shearing section of the braided protective layer 2 from damaging the inside of the charging cable, the braided protective layer 2 resists external shearing damage, and the insulating layer 3 prevents voltage leakage. This solves the problem that the charging cable is easily cut off and stolen in the prior art, and can effectively protect the interests of charging pile operators.

[0043] Example 2 The difference between this embodiment and Embodiment 1 is that the anti-theft device for the gun wire in this embodiment also includes a positioning component (not shown in the figure). The positioning component is disposed between the gun wire body and the insulation layer, and is located at the second end of the gun wire body. The positioning component includes a positioning chip and a wireless communication module. The positioning chip can accurately determine the location of the gun wire, and the wireless communication module can transmit the positioning information to the control terminal in real time, enabling the positioning component to communicate with the control terminal. Optionally, the positioning component can also be other devices with positioning and communication functions, such as a GPS locator or a GPS chip. The specific type can be selected as needed, and it can communicate with control terminals such as computing devices. When the gun wire is stolen, the operator can obtain the location information of the gun wire in a timely manner through the control terminal, facilitating the retrieval of the gun wire.

[0044] The implementation principle of this embodiment is as follows: a positioning component is added to the multi-layered protective structure, further improving the anti-theft capability of the cable. The positioning component obtains the cable's location information in real time, enabling timely tracking after the cable is stolen, thus reducing losses for the operator.

[0045] Example 3 like Figure 2 As shown, the difference between this embodiment and Embodiment 2 is that the anti-theft device for the gun wire in this embodiment also includes an auxiliary layer 4, which is fitted inside the braided protective layer 2, so that both the anti-stab layer 1 and the gun wire body 100 are located inside the auxiliary layer 4. The auxiliary layer 4 adopts the same structure and material as the braided protective layer 2, that is, it is provided with two layers of 316L stainless steel braided mesh, but the thickness is not limited.

[0046] Example 4 like Figure 3 and Figure 4As shown, the difference between this embodiment and Embodiment 3 is that the auxiliary layer 4 includes an integrally formed wrapping portion 41 and protrusions 42. The wrapping portion 41 is fitted inside the braided protective layer 2, and both the puncture-resistant layer 1 and the cable body 100 are located inside the wrapping portion 41. Several protrusions 42 are provided, and these protrusions 42 are spirally coiled around the outer periphery of the wrapping portion 41. The wrapping portion 41 further protects the cable body 100, and the spiral coiling structure of the protrusions 42 increases the strength of the auxiliary layer 4, helps to disperse the load, and improves shear resistance. Along the extending direction of the protrusions 42, multiple connecting portions 43 are spaced apart between adjacent protrusions 42. The connecting portions 43 can strengthen the connection between the protrusions 42 and improve the stability of the overall structure. Simultaneously, the spaced connecting portions 43 can also act as a locking mechanism against cable shears, increasing the difficulty of cutting. Optionally, the connecting portions 43 can also be other reinforcing structures, such as mesh reinforcing ribs. The material of the auxiliary layer 4 is not limited, as long as it can provide shear resistance.

[0047] The connecting portion 43 can be a plate-like structure, and it can be curved, protruding beyond the top of the protrusion 42 to provide stable support for the woven protective layer 2. It is spaced apart from the wrapping portion 41 on its lower side to improve shear resistance while reducing weight. In this embodiment, a positioning element can be disposed between the connecting portion 43 and the wrapping portion 41 to minimize its impact on structural performance.

[0048] The implementation principle of this embodiment is as follows: By adding auxiliary layer 4, the shear resistance of the wire is further improved. The special structural design of auxiliary layer 4 allows the wire to better disperse and resist external forces when subjected to shear force, thus enhancing the anti-theft performance of the wire.

[0049] It is understandable that the device also includes necessary structures for connection, support, positioning, limiting and control functions, so that the device can operate normally; the shape, size, material and number of each part of the device can be determined as needed, as long as the corresponding functions can be achieved.

[0050] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
