Description

Technical Field

[0001] This disclosure relates to the field of charging technology, and in particular to a charging gun and a charging pile. Background Technology

[0002] With the rapid development of the new energy vehicle industry, users are demanding increasingly higher charging power. This has led to larger and larger diameter cables for charging guns. However, the increased cable diameter makes the cables difficult to bend and twist, making it very strenuous for users to plug in and unplug the charging gun. Utility Model Content

[0003] This disclosure provides a charging gun and a charging station. A portion of the outer sheath of the charging gun's cable is replaced with a soft sheath, making the cable easier to bend and twist, facilitating user insertion and removal of the charging gun. The technical solutions for the charging gun and charging station are described below.

[0004] In a first aspect, this disclosure provides a charging gun. The charging gun includes a charging gun head and a cable. The charging gun head includes a cable channel. The cable includes a wire core and an outer sheath, with the wire core passing through the outer sheath. The outer sheath includes a first rigid sheath, a flexible sheath, and a second rigid sheath connected in sequence. The first rigid sheath passes through the cable channel, while the flexible sheath and the second rigid sheath are located outside the cable channel.

[0005] The technical solution provided in this disclosure, by setting an outer sheath including a soft sheath outside the cable channel of the charging gun head, allows the cable to bend and twist more easily at the soft sheath. Thus, during the user's insertion and removal of the charging gun, the cable can adaptively bend and twist at the soft sheath, making it easier for the user to insert and remove the charging gun with less effort, improving the user experience. Furthermore, by setting a first hard sheath (instead of a soft sheath) through the cable channel of the charging gun head, it helps to improve the reliability of the connection between the cable and the charging gun head, as well as the sealing performance between the outer wall of the first hard sheath and the inner wall of the cable channel.

[0006] In one implementation, a portion of the first rigid sheath is located outside the cable channel. This further improves the seal between the outer wall of the first rigid sheath and the inner wall of the cable channel.

[0007] In one implementation, one end of the soft sheath is fitted onto the first hard sheath, and the other end is fitted onto the second hard sheath. This reduces the need for modifications to the cable production line. For example, the cable production line can remain unchanged, and after the cable is manufactured, a portion of the hard sheath can be stripped, and the soft sheath can be fitted onto the stripped portion.

[0008] In one implementation, the inner walls at both ends of the soft sheath are provided with multiple first protruding rings, which are fitted onto the first hard sheath and the second hard sheath. When the first protruding rings are compressed, they effectively seal the gaps between the inner walls of both ends of the soft sheath and the outer walls of the first and second hard sheaths.

[0009] In one implementation, the outer walls of the first hard sheath and the second hard sheath are provided with a plurality of first protruding rings, and the soft sheath is fitted onto the first protruding rings.

[0010] In one implementation, the charging gun further includes two clamping components. One clamping component clamps the portion of the soft sheath that covers the first hard sheath, and the other clamping component clamps the portion of the soft sheath that covers the second hard sheath. The clamping components can be cable ties, metal rings, ropes, or tape, etc. This improves the reliability of the connection between the two ends of the soft sheath and the first and second hard sheaths, as well as the reliability of the sealing and protective performance.

[0011] In one implementation, the outer walls at both ends of the flexible sheath include second protruding rings. Two clamping members are arranged between the two second protruding rings. The second protruding rings are used to prevent the clamping members from disengaging from the flexible sheath. This improves the reliability of the clamping members clamping the flexible sheath.

[0012] In one implementation, the two ends of the soft sheath are connected to the first hard sheath and the second hard sheath through a secondary injection molding process. This secondary injection molding can be understood as follows: during the processing of the outer sheath, the first and second hard sheaths are first formed by a single injection molding process, followed by a secondary injection molding process to form the soft sheath. During this secondary injection molding process, the two ends of the soft sheath are connected to the first and second hard sheaths.

[0013] The technical solution disclosed herein, by connecting the two ends of the soft sheath to the first and second hard sheaths through secondary injection molding, achieves higher structural strength and better sealing performance at the connection points between the two ends of the soft sheath and the first and second hard sheaths. Furthermore, the secondary injection molding connection method facilitates the installation of the soft sheath and improves the processing speed of the cable and charging gun.

[0014] In one implementation, the outer sheath is integrally injection molded, the diameter of the soft sheath is larger than the diameters of the first hard sheath and the second hard sheath, and the soft sheath includes a corrugated tube structure.

[0015] The technical solution disclosed herein integrates the soft sheath with the first and second hard sheaths at both ends, resulting in higher structural strength and better sealing performance at the connection point. Furthermore, the outer sheath is integrally injection molded, leading to high processing efficiency. Moreover, it does not increase the number of parts in the charging gun, saving raw material costs and improving the utilization rate of production resources.

[0016] In one implementation, the flexible sheath includes a corrugated section, two transition sections, and two connecting sections. The corrugated section includes a bellows structure. One end of each of the two transition sections is connected to both ends of the corrugated section, and the other end of each transition section is connected to one end of each connecting section. The two connecting sections connect to a first rigid sheath and a second rigid sheath, respectively. The diameter of the transition sections gradually decreases from the middle to both ends of the flexible sheath.

[0017] In one implementation, a portion of the first hard sheath is located outside the cable channel, and the length of this portion is less than 10cm. This prevents the soft sheath from being too far from the charging head, which would make it easier for the charging head to bend and twist at the connection point with the cable, thus meeting practical usage requirements.

[0018] In one implementation, the distance between the first hard sheath and the second hard sheath is greater than 8cm and less than 30cm. The distance is greater than 8cm to ensure the soft sheath is not too short, guaranteeing sufficient length for bending and twisting. The distance is less than 30cm to prevent the soft sheath from being too long, minimizing its impact on the protective performance of the outer sheath.

[0019] Secondly, this disclosure provides a charging pile. The charging pile includes a charging module and a charging gun as described in any of the first aspects, wherein the end of the charging gun's cable away from the charging gun head is connected to the charging module. The charging pile can be an integrated charging pile or a split-type charging pile. Attached Figure Description

[0037] 3. Fasteners. Detailed Implementation

[0038] With the rapid development of the new energy vehicle industry, charging piles have also developed rapidly. Charging piles include integrated charging piles and split charging piles. Figure 1 A schematic diagram of an integrated charging station is shown, such as... Figure 1 As shown, the integrated charging pile includes a charging module 100 (or power conversion module), a charging gun 200, and an equipment cabinet 300. The charging module 100 is located in the equipment cabinet 300. The charging gun 200 includes a charging gun head 1 and a cable 2, one end of which is connected to the charging module 100, and the other end is connected to the charging gun head 1. Figure 2 A schematic diagram of a split-type charging station is shown, such as... Figure 2As shown, the split-type charging pile includes a charging module 100, multiple charging guns 200, multiple equipment cabinets 300, and a main unit cabinet 400. The charging module 100 is located in the main unit cabinet 400 and is connected to the multiple equipment cabinets 300 via cables. The equipment cabinets 300 are connected to the charging guns 200. The equipment cabinets 300 and their corresponding charging guns 200 together form a charging terminal, and the charging module 100 in the main unit cabinet 400 can supply power to the multiple charging terminals.

[0039] The cable 2 of the charging gun 200 generally includes a wire core and an outer sheath surrounding the wire core. The wire core typically includes conductors and may also include liquid cooling pipes for transmitting coolant. The outer sheath protects the wire core, providing waterproofing and dustproofing. As charging power gradually expands to the megawatt level, the wire diameter of the cable 2 of the charging gun 200 is also increasing, which reduces the flexibility of the cable 2. Furthermore, because the charging gun 200 needs to withstand harsh conditions such as drops, crushing, and low temperatures, the outer sheath of the cable 2 is required to have high rigidity. In addition, the connection between the charging gun head 1 and the cable 2 is rigid, resulting in high stress from bending and twisting of the cable 2 when the charging gun 200 is plugged in and out, making operation difficult for users and resulting in a poor user experience.

[0040] In view of the above-mentioned technical problems, this disclosure provides a charging gun 200. A portion of the outer sheath of the charging gun 200 is replaced with a soft sheath, making it easier for the cable 2 to bend and twist at the soft sheath, allowing the user to plug and unplug the charging gun 200 with less effort. The charging gun provided in this disclosure embodiment will now be described by way of example.

[0041] Figure 3 A schematic diagram of the charging gun is shown. Figure 4 An exploded view of the charging gun is shown. Figure 3 and Figure 4 As shown, the charging gun 200 includes a charging gun head 1 and a cable 2. The charging gun head 1 includes a cable channel 11. The cable 2 includes a wire core 21 and an outer sheath 22, with the wire core 21 passing through the outer sheath 22. The outer sheath 22 includes a first hard sheath 221, a soft sheath 222, and a second hard sheath 223 connected in sequence. The first hard sheath 221 passes through the cable channel 11, while the soft sheath 222 and the second hard sheath 223 are located outside the cable channel 11.

[0042] The soft sheath 222 is more easily bent and twisted than the first hard sheath 221 and the second hard sheath 223. To achieve this greater flexibility, the soft sheath 222 can be made of a material with higher softness (or lower hardness and higher elasticity) than the first hard sheath 221 and the second hard sheath 223. For example, the first hard sheath 221 and the second hard sheath 223 are made of thermoplastic polyurethane elastomer rubber (TPU), while the soft sheath 222 is made of a softer rubber, plastic, or silicone. Alternatively, the soft sheath 222 can have a different diameter, wall thickness, or structure than the first hard sheath 221 and the second hard sheath 223. For example, the soft sheath 222 can have a larger diameter, a thinner wall, or a corrugated structure.

[0043] The technical solution provided in this embodiment of the disclosure, by setting the outer sheath 22 to include a soft sheath 222 located outside the charging gun head 1, allows the cable 2 to bend and twist more easily at the soft sheath 222. Thus, during the user's insertion and removal of the charging gun, the cable 2 can adaptively bend and twist at the soft sheath 222, making it easier for the user to insert and remove the charging gun with less effort, improving the user experience. Furthermore, by setting a first hard sheath 221 (instead of a soft sheath 222) to pass through the cable channel 11 of the charging gun head 1, it helps to ensure the reliability of the connection between the cable 2 and the charging gun head 1, as well as the sealing between the outer wall of the first hard sheath 221 and the inner wall of the cable channel 11.

[0044] In some examples, to further improve the seal between the outer wall of the first hard sheath 221 and the inner wall of the cable channel 11, a portion of the first hard sheath 221 is located outside the cable channel 11. Furthermore, having the first hard sheath 221 located outside the cable channel 11 also facilitates the connection of the first hard sheath 221 to the soft sheath 222.

[0045] Understandably, in related technologies, the connection point between the charging gun head 1 and the cable 2 is the least likely to experience bending and twisting. Therefore, the soft sheath 222 can be positioned close to the charging gun head 1. Figure 5 A schematic diagram showing the relevant dimensions of the outer sheath 22 of cable 2 is provided. In some examples, such as... Figure 5 As shown, the length A of the portion of the first hard sheath 221 located outside the cable channel 11 is less than 15 cm to prevent the soft sheath 222 from being too far from the charging head 1. In other examples, the aforementioned A is less than 10 cm or 5 cm.

[0046] In some examples, such as Figure 5As shown, the distance B between the soft sheath 222 and the charging gun head 1 is less than 15cm. In other examples, the distance B is less than 10cm, 5cm, or 3cm.

[0047] In some examples, such as Figure 5 As shown, the distance C between the first hard sheath 221 and the second hard sheath 223 is greater than 8cm, so that the soft sheath 222 has sufficient length to bend and twist. In addition, if the soft sheath 222 is too long, it will not be conducive to ensuring the protective performance of the outer sheath 22. Therefore, the distance C between the first hard sheath 221 and the second hard sheath 223 is set to be less than 30cm.

[0048] The distance C between the first hard sheath 221 and the second hard sheath 223 is less than or equal to the length D of the soft sheath 222, and they are approximately equal. Therefore, the length D of the soft sheath 222 can be set to be greater than 10cm and less than 35cm.

[0049] The connection method between the two ends of the soft sheath 222 and the first hard sheath 221 and the second hard sheath 223 will be described by way of example below.

[0050] (1) In some examples, such as Figure 6 and Figure 7 As shown, one end of the soft sheath 222 is fitted onto the first hard sheath 221, and the other end is fitted onto the second hard sheath 223. Wherein, Figure 6 A three-dimensional cross-sectional view of cable 2 is shown. Figure 7 A cross-sectional view of cable 2 is shown. The two ends of the soft sheath 222 can be interference-fitted with the first hard sheath 221 and the second hard sheath 223 to ensure the sealing and protection performance of the two ends of the soft sheath 222 with the first hard sheath 221 and the second hard sheath 223.

[0051] The technical solution provided in this disclosure reduces the need for modifications to the production line of the cable 2 by setting the two ends of the soft sheath 222 to be fitted onto the first hard sheath 221 and the second hard sheath 223. For example, the production line of the cable 2 can be kept unchanged, and after the cable 2 is produced, a portion of the hard sheath can be stripped off, and the soft sheath 222 can be fitted onto the stripped portion.

[0052] Figure 8 It shows Figure 7 An enlarged view of the part outlined by the dashed box. Figure 9 A schematic diagram of the soft sheath 222 is shown. In some examples, to further improve the sealing and protective performance of the inner walls at both ends of the soft sheath 222 with the outer walls of the first hard sheath 221 and the second hard sheath 223, such as... Figure 8 and Figure 9As shown, the inner walls of both ends of the soft sheath 222 are provided with multiple first protruding rings 2221, which are fitted onto the first hard sheath 221 and the second hard sheath 223. In this way, when the first protruding rings 2221 are compressed, they can effectively seal the gaps between the inner walls of both ends of the soft sheath 222 and the outer walls of the first hard sheath 221 and the second hard sheath 223.

[0053] Accordingly, in some examples, multiple annular grooves are provided on the outer wall of the first hard sheath 221 and the outer wall of the second hard sheath 223, and multiple first protruding rings 2221 can extend into the multiple annular grooves respectively. Of course, the outer walls of the first hard sheath 221 and the outer walls of the second hard sheath 223 may not be provided with annular grooves, and this disclosure does not limit this.

[0054] Of course, in other examples, a first protruding ring 2221 can also be provided on the outer wall of the first hard sheath 221 and the outer wall of the second hard sheath 223, and the soft sheath 222 can be fitted onto the first protruding ring 2221. In this way, it can also seal the gaps between the inner walls of both ends of the soft sheath 222 and the outer walls of the first hard sheath 221 and the second hard sheath 223. Accordingly, annular grooves can be formed on the inner walls of both ends of the soft sheath 222, and the first protruding ring 2221 can be embedded in the annular grooves.

[0055] Figure 10 A schematic diagram of the soft sheath 222 and the clamping member 3 is shown. In some examples, to further improve the sealing and protection performance, and to ensure the reliability of the connection between the soft sheath 222 and the first hard sheath 221 and the second hard sheath 223, such as... Figures 6-8 and Figure 10 As shown, the charging gun also includes two clamping components 3. One clamping component 3 clamps the portion of the soft sheath 222 that covers the first hard sheath 221, and the other clamping component 3 clamps the portion of the soft sheath 222 that covers the second hard sheath 223. The clamping component 3 can be a cable tie, metal ring, rope, or tape, etc.

[0056] In some examples, such as Figures 6-10 As shown, the outer walls at both ends of the soft sheath 222 include second protruding rings 2222, and two clamping members 3 are arranged between the two second protruding rings 2222. The second protruding rings 2222 are used to prevent the clamping members 3 from disengaging from the soft sheath 222, so as to ensure the reliability of the clamping members 3 clamping the soft sheath 222.

[0057] (2) In some examples, such as Figure 11 As shown, the two ends of the soft sheath 222 are connected to the first hard sheath 221 and the second hard sheath 223 through a secondary injection molding process. Among them, Figure 11A schematic diagram of the second type of cable 2 is shown. Secondary injection molding can be understood as follows: during the processing of the outer sheath 22, a first hard sheath 221 and a second hard sheath 223 are formed through a single injection molding process, followed by a second injection molding process to form the soft sheath 222. During the secondary injection molding process, the two ends of the soft sheath 222 are connected to the first hard sheath 221 and the second hard sheath 223.

[0058] The technical solution provided in this disclosure, by connecting the two ends of the soft sheath 222 to the first hard sheath 221 and the second hard sheath 223 through secondary injection molding, achieves higher structural strength and better sealing performance at the connection points between the two ends of the soft sheath 222 and the first hard sheath 221 and the second hard sheath 223. Furthermore, the secondary injection molding connection method facilitates the installation of the soft sheath 222 and improves the processing speed of the cable 2 and the charging gun.

[0059] (3) In some examples, such as Figure 12 and Figure 13 As shown, the outer sheath 22 is integrally injection molded. The diameter of the soft sheath 222 is larger than the diameters of the first hard sheath 221 and the second hard sheath 223, and the soft sheath 222 includes a corrugated tube structure. Among these features, Figure 12 A schematic diagram of the third type of cable 2 is shown. Figure 13 A cross-sectional view of the third type of cable, 2, is shown. From Figure 12 and Figure 13 It can be clearly seen that the soft sheath 222 is integrally formed with the first hard sheath 221 and the second hard sheath 223.

[0060] The technical solution provided in this disclosure integrates the two ends of the soft sheath 222 with the first hard sheath 221 and the second hard sheath 223, resulting in higher reliability and better sealing performance at the connection. Furthermore, the outer sheath 22 is integrally injection molded, leading to high processing efficiency. This also avoids increasing the number of parts in the charging gun, saving raw material costs and improving the utilization rate of production materials.

[0061] Since the outer sheath 22 is integrally injection molded, the material of the soft sheath 222 is the same as that of the first hard sheath 221 and the second hard sheath 223. Therefore, in order to make the soft sheath 222 easier to bend and twist, the soft sheath 222 should have a larger diameter. Meanwhile, if... Figure 12 and Figure 13 As shown, the soft sheath 222 is thermoplastically stacked to form a corrugated pipe structure. Alternatively, it can be understood that the soft sheath 222 is in a state of axial compression.

[0062] The specific form of the soft sheath 222 is not limited in this embodiment. The soft sheath 222 can be a corrugated pipe or a soft rubber sleeve, etc. Hereinafter, taking a corrugated pipe as an example, the structure of the soft sheath 222 will be described by way of example.

[0063] In some examples, such as Figure 7 , Figure 9 and Figure 10 As shown, the soft sheath 222 includes a corrugated section 2223, two transition sections 2224, and two connecting sections 2225. The corrugated section 2223 includes a bellows structure. One end of each of the two transition sections 2224 is connected to both ends of the corrugated section 2223, and the other end of each transition section 2224 is connected to one end of each connecting section 2225. The two connecting sections 2225 are connected to the first hard sheath 221 and the second hard sheath 223, respectively. The diameter of the corrugated section 2223 is larger than the diameter of the connecting sections 2225. The diameter of the transition sections 2224 gradually decreases from the middle to both ends of the soft sheath 222.

[0064] In some examples, such as Figure 6 and Figure 7 As shown, the two connecting segments 2225 are respectively fitted with a first hard sheath 221 and a second hard sheath 223. The inner walls of the two connecting segments 2225 include a first protruding ring 2221. The outer walls of the two connecting segments 2225 include a second protruding ring 2222 to prevent the clamping member 3 from disengaging.

[0065] In other examples, such as Figure 11 As shown, the two connecting segments 2225 are connected to the first hard sheath 221 and the second hard sheath 223 respectively through a secondary injection molding process. Because the connection is achieved through secondary injection molding, therefore, as... Figure 11 As shown, the connecting segment 2225 may not have a second protruding ring 2222.

[0066] It should be noted that in some examples, the soft sheath 222 may not include the connecting section 2225, but instead is directly connected to the first hard sheath 221 and the second hard sheath 223 by the transition section 2224, for example, Figure 12 and Figure 13 The scheme shown is as follows. In some other examples, the soft sheath 222 may not include the transition section 2224, in which case the two ends of the corrugated section 2223 are directly connected to two connecting sections 2225, which are respectively connected to the first hard sheath 221 and the second hard sheath 223. In some other examples, the soft sheath 222 may only include the corrugated section 2223, with the two ends of the corrugated section 2223 directly connected to the first hard sheath 221 and the second hard sheath 223.

[0067] This disclosure also provides a charging pile. The charging pile includes a charging module 100 and the aforementioned charging gun 200. The end of the cable 2 of the charging gun 200 away from the charging gun head 1 is connected to the charging module 100. The charging pile can be an integrated charging pile or a split-type charging pile; details can be found in the foregoing description and will not be repeated here.
