Description

Technical Field

[0001] This utility model relates to the technical field of electronic lock accessories for charging guns, and in particular to a hose assembly. Background Technology

[0002] With the rapid development of the new energy vehicle industry, electric vehicles are powered by battery packs. How to charge electric vehicles is an important issue. Currently, DC charging guns used in the market usually need to be equipped with electronic locks to ensure the reliability and safety of charging. This ensures that the charging gun is effectively locked and does not fall off when the electric vehicle is using the charging gun, and prevents the charging gun from being pulled out while the power is on. In the electronic lock system of the charging gun, the metal rope mainly serves as a mechanical backup or redundant design for linkage control. When the electric / pneumatic / hydraulic system of the electronic lock cannot be unlocked due to a fault (such as power failure, control module damage, hose leakage), the metal rope can be manually pulled to trigger the mechanical unlocking mechanism and forcibly release the charging gun.

[0003] Currently, a flexible hose is installed on the outside of the metal rope to protect it. However, the handle plate connected to the metal rope is usually left hanging outside. This can easily cause the handle plate to shake during driving, resulting in impact noises and damage inside the vehicle. In addition, the seal between the hose and the metal rope is poor, making it easy for water to enter and cause the metal rope to rust, thus affecting its service life. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide a hose assembly to solve the problems mentioned in the background art.

[0005] A hose assembly, comprising:

[0035] like Figures 1-5 As shown, a hose assembly includes:

[0036] Corrugated hose 1;

[0037] Metal rope 2, which is disposed inside the corrugated hose 1;

[0038] Waterproof component 3 is installed between the first end of the metal rope 2 and the first end of the corrugated hose 1. The waterproof component 3 is used for waterproof sealing between the first end of the metal rope 2 and the first end of the corrugated hose 1. By setting the waterproof component 3, the sealing between the corrugated hose 1 and the metal rope 2 can be improved, thereby preventing water from entering the interior of the corrugated hose 1 and thus achieving waterproofing.

[0039] The handle plate assembly 4 is connected to the end of the metal rope 2 and is fastened to the corrugated hose 1. When used in a vehicle, simply fasten and fix the handle plate assembly 4 to the corrugated hose 1 to avoid the adverse situation of impact noise and damage caused by shaking the handle plate assembly 4 inside the vehicle.

[0040] like Figures 1-4 As shown, the waterproof component 3 includes:

[0041] A hose fixing cover 31 is inserted into the head end of the corrugated hose 1. The head end of the metal rope 2 passes through the inside of the hose fixing cover 31. A slot 311 is opened at the upper end of the hose fixing cover 31. A guide sleeve 312 is fixed at one end of the hose fixing cover 31. The guide sleeve 312 is inserted into the inside of the head end of the corrugated hose 1. The head end of the metal rope 2 passes through the guide sleeve 312 and the slot 311 in sequence. The hose fixing cover 31 is used to be inserted and fixed with the electronic lock, so that the metal rope 2 passes through the hose fixing cover 31 and connects to the electronic lock. The guide sleeve 312 of the hose fixing cover 31 is inserted into the inside of the head end of the corrugated hose 1.

[0042] The silicone sealing component 32 is inserted between the hose fixing cover 31 and the head end of the corrugated hose 1. The metal rope 2 passes through the silicone sealing component 32. By inserting the silicone sealing component 32 between the hose fixing cover 31 and the head end of the corrugated hose 1, the sealing performance between the hose fixing cover 31 and the head end of the corrugated hose 1 can be improved.

[0043] like Figure 4 As shown, the silicone sealing assembly 32 includes:

[0044] Waterproof silicone plug 321 is inserted into slot 311. The first end of metal rope 2 is inserted through waterproof silicone plug 321. Waterproof silicone plug 321 is mainly inserted into slot 311, while metal rope 2 passes through the center of waterproof silicone plug 321. This can improve the sealing between metal rope 2 and hose fixing cover 31.

[0045] A second waterproof silicone plug 322 is fitted over the guide sleeve 312. The first end of the corrugated hose 1 is inserted into the other end of the second waterproof silicone plug 322. A first waterproof silicone plug 321 is engaged with the second waterproof silicone plug 322. A locking block 3211 is fixed to one end of the first waterproof silicone plug 321 near the second waterproof silicone plug 322. A protrusion 3221, integral with the second waterproof silicone plug 322, is provided on the upper end of the inner wall of the second waterproof silicone plug 322. A groove is provided on the upper end of the locking block 3211. The protrusion 3221 is inserted into the groove to secure the waterproof silicone plug. After the first 321 is inserted into the slot 311, the second waterproof silicone plug 322 is first put on the outside of the guide sleeve 312. At this time, the locking block 3211 and the boss 3221 are engaged, so that the second waterproof silicone plug 322 and the first waterproof silicone plug 321 are engaged as one unit. Then, when the first end of the corrugated hose 1 is put on the outside of the guide sleeve 312, the first end of the corrugated hose 1 is inserted into the inside of one end of the second waterproof silicone plug 322. This improves the sealing between the corrugated hose 1 and the hose fixing cover 31, so as to prevent water from entering the inside of the corrugated hose 1, thereby achieving waterproofing.

[0046] like Figures 1-2 As shown, the hose assembly also includes:

[0047] Cable tie 5 is located on one side of the waterproof silicone plug 322 and is fixedly sleeved on the outside of the first end of the corrugated hose 1. After the first end of the corrugated hose 1 is inserted into one end of the waterproof silicone plug 322, the cable tie 5 can be used to tighten the first end of the corrugated hose 1, so that the first end of the corrugated hose 1 is fixed to the guide sleeve 312.

[0048] like Figure 5 As shown, the pull handle component 4 includes:

[0049] A handle plate 41 is connected to the end of the metal rope 2. The handle plate 41 is provided with a slot, and the end of the metal rope 2 is engaged with the slot. The metal rope 2 can be placed into the slot to complete the assembly.

[0050] The C-shaped buckle 42 is fixed integrally to the surface of the handle plate 41. The C-shaped buckle 42 is connected to the corrugated hose 1. Because the C-shaped buckle 42 is made of elastic material, it has a certain elasticity. Since the outer diameter of the corrugated hose 1 is smaller than the opening diameter of the C-shaped buckle 42, when used in a vehicle, simply fixing the C-shaped buckle 42 to the corrugated hose 1 will ensure that the handle plate 41 and the corrugated hose 1 are fixed and will not shake. This will avoid the adverse situation of impact noise and damage caused by shaking the handle plate 41 inside the vehicle.
