Description

Technical Field

[0001] This utility model relates to the field of new energy vehicles, and in particular to a charging gun cable fixing assembly and a new energy vehicle charging gun. Background Technology

[0002] With the development of science and technology, new energy vehicles are gaining increasing popularity among users due to their convenience and technological appeal. A new energy vehicle charging gun is a device used to charge electric vehicles or other new energy vehicles. The charging gun is part of the electric vehicle charging infrastructure and is used to transfer electrical energy to the electric vehicle's battery.

[0003] Most existing charging guns for new energy vehicles are installed outdoors along with charging piles, making them susceptible to weather conditions. For example, during the rainy season, the charging guns are easily washed by rainwater, causing moisture to accumulate at the charging gun head. When the charging gun gets damp, the internal wires are prone to short circuits, which can damage the charging gun, resulting in not only losses but also safety hazards.

[0004] In addition, with repeated use, the cable at the end of the charging gun may become loose after being pulled multiple times, which makes it easier for electrical connections to become loose and for the circuit to get damp. Summary of the Invention

[0005] The purpose of this utility model is to provide a charging gun cable fixing assembly and a new energy vehicle charging gun to solve the problems of loose electrical connections and moisture.

[0006] To achieve this objective, the present invention adopts the following technical solution: In a first aspect, this utility model relates to a charging gun cable fixing assembly, including a metal fixing ring, a soft rubber part, and a charging gun rear cover. The rear cover has a first cable hole and several mounting holes. The soft rubber part has a second cable hole and several through holes. The metal fixing ring has a third cable hole and several threaded holes. The soft rubber part is clamped between the metal fixing ring and the rear cover. The cable passes through the first to third cable holes. Several long screws pass through the mounting holes of the rear cover and the through holes of the soft rubber part and can be adjusted and assembled in the corresponding threaded holes of the metal fixing ring, thereby adjusting the distance between the rear cover and the metal fixing ring, so that the soft rubber part deforms to press the cable and seal the first cable hole and the third cable hole.

[0007] In the connection structure with the charging gun mechanism, the rear cover has several mounting holes, and each mounting hole is equipped with a short screw for fixing to the handle of the charging gun.

[0008] To ensure a tight seal, a first sealing edge is provided on one side of the second cable hole and a second sealing edge is provided on the other side of the soft rubber component. The first sealing edge is used to tightly seal the first cable hole, and the second sealing edge is used to tightly seal the third cable hole.

[0009] Secondly, this utility model relates to a new energy vehicle charging gun, including a handle and a cable. The cable is sealed and installed in the handle by a cable fixing assembly. The cable fixing assembly includes a metal fixing ring, a soft rubber part, and a rear cover of the charging gun. The rear cover has a first cable hole and several mounting holes. The soft rubber part has a second cable hole and several through holes. The metal fixing ring has a third cable hole and several threaded holes. The soft rubber part is clamped between the metal fixing ring and the rear cover. The cable passes through the first to third cable holes. Several long screws pass through the mounting holes of the rear cover and the through holes of the soft rubber part and can be adjusted and fitted into the corresponding threaded holes of the metal fixing ring, thereby adjusting the distance between the rear cover and the metal fixing ring, so that the soft rubber part deforms and presses the cable and the inner wall of the handle, and seals the first cable hole, the third cable hole, and the handle.

[0010] Preferably, the rear cover has several mounting holes, each with a short screw, and the rear end of the gun handle has several fixing holes for engaging with the short screws to fix the rear cover and cable fixing assembly in the gun handle.

[0011] To ensure a secure connection, the soft rubber part has several intermediate clearance grooves to avoid the short screws, and the metal retaining ring has several end clearance grooves to avoid the short screws.

[0012] The gun handle includes a housing and forms an inner cavity. A charging connector is fixedly connected to the front of the gun handle, and the gun handle includes a charging button.

[0013] In practice, the charging connector includes a positive charging terminal, a negative charging terminal, a grounding terminal, and a connection control terminal. The cable is a bundled connection cable that extends from the rear of the gun handle into the inner cavity and is electrically connected to the positive charging terminal, negative charging terminal, grounding terminal, and connection control terminal of the charging connector, respectively.

[0014] In order to align with the charging interface of new energy vehicles, the charging connector has several positioning slots for the new energy vehicle charging interface to be used.

[0015] To facilitate assembly, a positioning inner ring is provided on the inner edge of the rear cavity of the gun handle, and the rear cover includes a positioning outer ring. When assembling the cable fixing assembly, the positioning outer ring of the rear cover is aligned with and covers the positioning inner ring to achieve pre-positioning.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention relates to a charging gun cable fixing assembly and a new energy vehicle charging gun. The metal fixing ring and the rear cover of the charging gun adopt an adjustable sealing structure. The soft rubber part can flexibly fix the cable in the gun handle and improve the electrical connection stability between the cable and the conductive terminals in the charging connector.

[0017] This utility model discloses a charging gun cable fixing assembly and a new energy vehicle charging gun. By adjusting the distance between the rear cover and the metal fixing ring, the soft rubber part undergoes the required deformation, thereby pressing the cable and sealing the first cable hole of the rear cover, the third cable hole of the metal fixing ring, and all gaps between the assembly and the inner wall of the gun handle. During repeated use and external pulling, the cable is less likely to move or loosen. Adjusting the distance between the rear cover and the metal fixing ring improves the sealing performance, thereby enhancing the cable's waterproof performance and extending the charging gun's service life.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1 Please refer to Figure 3 , Figure 4 as well as Figure 5The charging gun cable fixing assembly A of this utility model embodiment includes a metal fixing ring 50, a soft rubber part 40, and a charging gun rear cover 30. In this embodiment, the metal fixing ring 50 is an aluminum fixing ring, but it is understood that it can also be made of other metal materials, such as an iron fixing ring or a copper fixing ring. The metal fixing ring 50 and the charging gun rear cover 30 adopt an adjustable sealing structure. The soft rubber part 40 can softly fix the cable in the gun handle 20 by sealing and squeezing, which improves the electrical connection stability between the cable and the conductive terminals in the charging connector; on the other hand, the cable 10 is not easy to move or loosen during repeated use and external pulling.

[0026] like Figure 5 As shown, the rear cover 30 has a first cable hole 38, several assembly holes, and several mounting holes, for example... Figure 4 The mounting hole 351 and mounting hole 311 are shown. Each mounting hole contains a short screw for securing the charging gun handle 20, such as short screws 32, 34, and 36. The flexible rubber part 40 has a second cable hole 48 and several through holes, for example... Figure 4 The through hole 401 is shown. The metal retaining ring 50 has a third cable hole 58 and several threaded holes, such as... Figure 4 The threaded hole 521 is shown.

[0027] The metal retaining ring 50, the soft rubber part 40, and the rear cover 30 of the charging gun are pre-assembled and then locked to the handle 20 via the rear cover 30. The soft rubber part 40 is clamped between the metal retaining ring 50 and the rear cover 30. The cable 10 passes sequentially through the first cable hole 38 of the rear cover 30, the second cable hole 48 of the soft rubber part 40, and the third cable hole 58 of the metal retaining ring 50. Several long screws, for example... Figure 4 The medium-length screw 35 passes through the mounting hole 351 of the rear cover 30 and the through hole of the soft rubber part 40, and can be adjusted and fitted into the corresponding threaded hole 521 of the metal retaining ring 50, completing the initial fixation of the charging gun cable fixing assembly A, but not locking it. Please refer to the above. Figure 1 The distance D between the back cover 30 and the metal retaining ring 50 can be adjusted by loosening or tightening the long screw, so that the soft rubber part 40 can deform sufficiently to press the cable 10 and tightly seal the first cable hole 38 and the third cable hole 58.

[0028] Please refer to this as well. Figure 4 The soft rubber part 40 is provided with a first sealing edge 42 on one side of the second cable hole 48 and a second sealing edge 46 on the other side. The first sealing edge 42 is used to tightly seal the first cable hole 38 of the back cover 30, and the second sealing edge 46 is used to tightly seal the third cable hole 58 of the metal fixing ring 50, thereby tightly sealing the hole.

[0029] Example 2 Please refer to Figure 1 as well as Figure 2 The new energy vehicle charging gun in this embodiment uses the cable fixing component A in embodiment 1.

[0030] The new energy vehicle charging gun includes a handle 20 and a cable 10, with a charging connector 22 fixedly connected to the front of the handle 20. The cable 10 is sealed and installed in the handle 20 by a cable fixing assembly A.

[0031] As shown in the figure Figure 5 As shown, the gun handle 20 includes a housing 201 forming an inner cavity 203, and a charging connector 22 is fixedly connected to the front of the gun handle 20. The gun handle 20 includes a charging button 25. The cable 10 passes through the inner cavity 203 and is electrically connected to the charging connector 22. The cable fixing assembly A stably fixes and seals the cable 10 in the inner cavity 203.

[0032] Please refer to this as well. Figure 2 as well as Figure 6 The gun handle has a slot 207 at the outlet of the inner cavity. The charging connector 22 includes a frame, one end of which has a terminal mounting cavity, and the other end has a positioning flange 223 and a hook 224. The positioning flange 223 of the charging connector abuts against the front end of the gun handle 20, and the hook 224 is secured in the slot 207 in the inner cavity of the gun handle 20 and locked to the gun handle 20 by a fixing screw 27.

[0033] In terms of electrical connection, the charging connector 22 includes a positive charging terminal 91, a negative charging terminal 92, a grounding terminal, and a connection control terminal 93. The cable 10 is a bundled connection cable, extending from the rear of the gun handle 20 into the inner cavity 203 and electrically connected to the positive charging terminal 91, negative charging terminal 92, grounding terminal, and connection control terminal 93 of the charging connector 22. To accommodate the charging interface of new energy vehicles, the charging connector 22 has several positioning slots for mating with the charging interface of new energy vehicles, such as... Figure 1 The first positioning slot 221 and the second positioning slot 224 are shown.

[0034] As described in Example 1, the charging gun cable fixing assembly A includes a metal fixing ring 50, a soft rubber part 40, and a charging gun back cover 30.

[0035] The rear cover 30 has a first cable hole 38, several assembly holes, and several mounting holes, such as... Figure 4 The mounting hole 351 and mounting hole 311 are shown. Each mounting hole contains a short screw for securing the charging gun handle 20, such as the first short screw 32. The flexible rubber part 40 has a second cable hole 48 and several through holes, such as... Figure 4 The through hole 401 is shown. The metal retaining ring 50 has a third cable hole 58 and several threaded holes, such as... Figure 4The threaded hole 521 is shown. The soft rubber part 40 is clamped between the metal retaining ring 50 and the back cover 30. The cable 10 passes through the first cable hole 38 of the back cover 30, the second cable hole 48 of the soft rubber part 40 and the third cable hole 58 of the metal retaining ring 50 in sequence.

[0036] Several long screws, for example Figure 4 The medium-length screw 35 passes through the mounting hole 351 of the rear cover 30 and the through hole of the soft rubber part 40, and can be adjusted and fitted into the corresponding threaded hole 521 of the metal retaining ring 50, completing the initial fixation of the charging gun cable fixing assembly A. By loosening or tightening the long screw, the distance D between the rear cover 30 and the metal retaining ring 50 can be adjusted, so that the soft rubber part 40 can deform sufficiently to press the inner wall of the cable 10 and the gun handle 20, sealing the gaps between the first cable hole 38, the third cable hole 58, and the cable fixing assembly A and the gun handle 20.

[0037] To facilitate the installation of the cable fixing assembly A and the gun handle 20, the rear cover 30 has several mounting holes, such as... Figure 3 The first mounting hole 31 and the third mounting hole 33 are shown. A short screw is disposed in each mounting hole; for example, a first short screw 32 is disposed in the first mounting hole 31, and a third short screw 34 is disposed in the third mounting hole 33.

[0038] Please refer to Figure 5 as well as Figure 6 The gun handle 20 includes a housing 201 with several fixing holes, such as a second fixing hole 202 and a fourth fixing hole 204. These holes are used to secure the rear cover 30, along with other cable fixing components A, within the gun handle 20 by engaging with corresponding short screws. For example, the second fixing hole 202 engages with a corresponding second short screw 32, and the fourth fixing hole 204 engages with a corresponding fourth short screw 36. The rear cover 30 secures the entire cable fixing component A within the gun handle 20. To facilitate assembly, a positioning inner ring 206 is provided at the inner edge of the rear cavity of the gun handle 20. The rear cover 30 includes a positioning outer ring 37. When assembling the cable fixing component A, the positioning outer ring 37 of the rear cover 30 is aligned with and covers the positioning inner ring 206 to achieve pre-positioning before being fixed by short screws.

[0039] Please refer to Figure 3 as well as Figure 4 The soft rubber part 40 has several intermediate clearance grooves to avoid short screws used for component assembly, for example... Figure 4 The shown is a central clearance groove 411. The metal retaining ring 50 has several end clearance grooves for accommodating short screws, such as... Figure 4 The end relief groove 511 shown facilitates the secure assembly of the charging gun cable fixing component A.

[0040] like Figure 7 as well as Figure 8As shown, first, the back cover 30, the soft rubber part 40, and the metal retaining ring 50 are sequentially threaded through the cable 10. Several long screws are passed through the mounting holes 351 of the back cover 30 and the through holes of the soft rubber part 40, and are adjustablely fitted into the corresponding threaded holes 521 of the metal retaining ring 50, completing the initial fixation of the charging gun cable fixing assembly A, but not yet tightened. The distance D between the back cover 30 and the metal retaining ring 50 is adjusted by loosening or tightening the long screws, so that the soft rubber part 40 can deform sufficiently to press the cable 10. The soft rubber part 40 is made of silicone, and after being deformed under force, it blocks all gaps and squeezes the middle cable 10 and the gun handle 20.

[0041] The cable 10 and the gun handle 20 are compressed and subjected to friction to fix the cable 10 in place. This prevents the cable 10 from moving when subjected to external pulling force. The soft rubber part 40 fills the gap at the tail of the gun handle 20, which can block foreign objects from entering through the gap of the rear cover 30 and provide good waterproofing.

[0042] When using this new energy vehicle charging gun, connect the charging gun connector 22 on the new energy vehicle charging gun to the charging interface on the new energy vehicle, so that electrical energy can be transmitted to the new energy vehicle through the new energy vehicle charging gun to complete the charging.

[0043] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
