Description

Technical Field

[0001] This invention relates to the field of automotive charging head technology, and in particular to a multifunctional new energy vehicle charging head. Background Technology

[0002] New energy vehicle charging heads, also known as charging guns or charging plugs, are essential accessories in the charging process of new energy vehicles. Existing new energy vehicle charging heads pose a risk of leakage during use, which can cause electric shock and injury to operators if they are not careful. However, existing charging heads cannot detect leakage or isolate the leakage from the operator. During operation, drops or collisions can cause damage to the outer shell and internal components, even leading to damage to internal components. Dragging can also cause bending between the charging gun and the connecting cable, further causing damage. At the same time, during charging, the charging gun can overheat due to overload, which may even cause a fire. In addition, rain during charging can cause short circuits or electrical conduction at the connection between the charging gun and the car connector. Therefore, this application provides a multifunctional new energy vehicle charging head to meet the needs. Summary of the Invention

[0032] like Figures 1 to 6 As shown, an embodiment of the present invention provides a multifunctional new energy vehicle charger, including a charger mechanism 1, which includes a handheld part 101, a plug part 102, a switch 103 and a pipeline 105 connected to each other. The charger mechanism 1 also includes a power plug, a cable and a control protection box, which are prior art and are not shown in the figure; an outer protective mechanism 2 is installed on the charger mechanism 1 and serves as insulation and protection.

[0033] The outer protective mechanism 2 includes a leakage current detection component 21, a heat conduction component 22, a waterproof cover 23, and a retaining plate 25 connected to each other. The leakage current detection component 21 is connected to the handheld part 101. The heat conduction component 22 and the waterproof cover 23 are connected to the plug part 102. The waterproof cover 23 is made of insulating and elastic material. The retaining plate 25 is connected to the pipeline 105. The retaining plate 25 is U-shaped and its two ends are outwardly folded. The retaining plate 25 is snapped onto the pipeline 105. The leakage current detection component 21 includes a handheld unit 211 disposed between the retaining plate 25 and the heat conduction component 22. The handheld unit 211 is fixedly connected to the handheld part 101. The handheld unit 211 is provided with a leakage current detection unit 215.

[0034] like Figures 2 to 6 As shown, the handheld unit 211 includes a first outer protective plate 212 fixedly connected to the outer wall of one end of the handheld part 101. One end of the first outer protective plate 212 extends to the pipeline 105 and is snapped onto and fixedly connected to the clamping plate 25. The other end is connected to the heat-conducting component 22. The bottom end of the first outer protective plate 212 has an oblong hole for heat dissipation and to prevent rainwater accumulation. The inner wall of the first outer protective plate 212 is fixedly connected to a first isolation pad 213 that fits against the outer wall of the handheld part 101. The cooperation between the first outer protective plate 212 and the first isolation pad 213 is to facilitate the operator's handhold and to prevent electric shock when the charging head mechanism 1 leaks current.

[0035] The leakage detection unit 215 includes a pair of symmetrically arranged second outer protective plates 216. The side walls of the pair of second outer protective plates 216 that are far apart from each other are fixedly connected to the first outer protective plate 212. The end of the second outer protective plate 216 near the heat conduction component 22 is fixedly connected to a force-bearing plate 217 that fits against the outer wall of the handheld part 101. The side walls of the pair of second outer protective plates 216 that are close to each other are provided with arc-shaped mounting grooves. A fixing ring 218 is fixedly connected in the pair of arc-shaped mounting grooves. A test pen 219 extending between the second outer protective plate 216 and the handheld part 101 is fixedly connected to the inner ring of the fixing ring 218. The fixing ring 218 is made of insulating material. The arrangement of the second outer protective plate 216, the fixing ring 218 and the test pen 219 is to facilitate the operator to detect whether there is leakage on the charging head mechanism 1, and to use with the force-bearing plate 217 so that the second outer protective plate 216 and the test pen 219 can return to their original positions after operation.

[0036] The width of the first outer protective plate 212 decreases sequentially from one end near the heat-conducting component 22 to the other end. The inner wall shape of the first outer protective plate 212 near the heat-conducting component 22 matches the outer wall shape of the handle 101. The inner wall shape of the middle section of the first outer protective plate 212 matches and fits the outer wall shape at the connection between the handle 101 and the pipeline 105. A portion of the inner wall of the first outer protective plate 212 is fixedly connected to the outer wall of the handle 101. The other end of the first outer protective plate 212 is snapped onto and fitted to the outer wall of the pipeline 105. The first outer protective plate 212, the first isolation pad 213, and the second outer protective plate 216 are all made of insulating material. The force-bearing plate 217 is also made of insulating and elastic material. The insulating material is used to prevent electrical conductivity. The width of the second outer protective plate 216 decreases sequentially from one end near the heat-conducting component 22 to the other end. The inner wall shape of the second outer protective plate 216 near the heat-conducting component 22 matches and fits the outer wall shape of the handle 101. The inner wall shape of the middle section of the second outer protective plate 216 is adapted to and fits the outer wall shape at the connection between the handheld part 101 and the pipeline 105. The other end of the second outer protective plate 216 is snapped onto the outer wall of the pipeline 105 and fits therein. There are gaps between the pair of second outer protective plates 216, between the second outer protective plate 216 and the first outer protective plate 212, and between the second outer protective plate 216 and the heat-conducting component 22. The gaps between the pair of second outer protective plates 216 and between the second outer protective plate 216 and the first outer protective plate 212 are provided to facilitate heat dissipation and also to prevent rainwater accumulation. The gap between the second outer protective plate 216 and the heat-conducting component 22 is provided to prevent the second outer protective plate 216 from interfering with the operation. The first outer protective plate 212 and the pair of second outer protective plates 216 form an installation cavity that is fitted onto the handheld part 101. The purpose is to wrap the handheld part 101 and prevent the operator from contacting the handheld part 101 when holding it.

[0037] like Figures 3 to 6As shown, the heat-conducting component 22 includes an outer protective component for drop protection and cooling, and a waterproof component for waterproofing during charging. The outer protective component is installed on the plug portion 102, and the waterproof component is connected to the outer protective component. The outer protective component includes an outer sleeve 221 fitted onto the plug portion 102. The outer sleeve 221 is designed to protect the plug portion 102 and prevent direct contact with the operator. The outer sleeve 221 has a through hole 226 fitted onto the switch 103. To avoid interference with the use of the switch 103, multiple second isolation pads 222 are fixedly connected to the inner wall of the outer sleeve 221. A U-shaped plate 223 is fixedly connected to the inner wall of the second isolation pads 222 and adheres to the outer wall of the plug portion 102. The cooperation between the second isolation pads 222 and the U-shaped plate 223 is designed to provide cushioning when the charging head mechanism 1 is dropped. To prevent damage to the internal parts of the charging head mechanism 1 from vibration, and to conduct heat from the plug part 102 and prevent it from spontaneously combusting due to overheating, the top of the outer sheath 221 is fixedly connected to a waist-shaped plate 224 through a mounting hole. The top of the waist-shaped plate 224 is fixedly connected to a waist-shaped pressing piece 225 extending above the switch 103. The waist-shaped pressing piece 225 is provided with a weakening groove. The waist-shaped plate 224 and the waist-shaped pressing piece 225 are designed to isolate the operator from direct contact with the switch 103, further preventing leakage and electric shock to the operator. The inner wall shape of the outer sheath 221 is adapted to the outer wall shape of the plug part 102. The second isolation pad 222, the outer sheath 221 and the waist-shaped plate 224 are all made of insulating material. The U-shaped plate 223 and the waist-shaped pressing piece 225 are insulating and also made of elastic material.

[0038] The working principle of the technical solution provided by the present invention is as follows: During use, when the operator holds the charging head mechanism 1, it will first come into contact with the first outer protective plate 212 and the second outer protective plate 216. The operator can first place his thumb on the top of the test pen 219 and press it. The fixing ring 218 will drive the second outer protective plate 216 to be stressed at the same time, which will cause the force plate 217 to deform under the stress, and further cause the test pen 219 to come into contact with the charging head mechanism 1. If the test pen 219 lights up, it means that the charging head mechanism 1 is leaking electricity, and measures can be taken to cut off its power. If the test pen 219 does not light up, it means that the charging head mechanism 1 is not leaking electricity, and the next step of operation can be carried out.

[0039] Then, the charging head mechanism 1 is inserted into the car connector. During this process, the waterproof cover 23 will come into contact with and deform against the car body, and will further cover the car connector and the plug part 102 socket.

[0040] Then, by pressing the waist-shaped pressing piece 225 to deform it, it comes into contact with the switch 103, which further presses the switch 103, allowing the charging head mechanism 1 to supply power.

[0041] During use, when holding the handheld part 101, the cable 105 cannot be bent between the handheld part 101 under the action of the clamping plate 25. If the charging head mechanism 1 is dropped or collided, it will first come into contact with the outer sheath 221, the first outer protective plate 212 or the second outer protective plate 216. If the charging head mechanism 1 falls to the ground, it will first come into contact with the waterproof cover 23. The waterproof cover 23 deforms when impacted. When it collides with the outer sheath 221, the second isolation pad 222 and the U-shaped plate 223 will be squeezed. The U-shaped plate 223 will deform when squeezed and rebound after being subjected to force. When it collides with the handheld unit 211, the first isolation pad 213 will be squeezed. When it collides with the second outer protective plate 216, the force plate 217 will deform under force.

[0042] Meanwhile, the charging head mechanism 1 generates heat during use. The heat is conducted to the U-shaped plate 223, then to the second isolation pad 222, and further to the U-shaped plate 223, and then to the outer sheath 221. During this process, the heat is dissipated for the first time through the internal space of the second isolation pad 222, then through the gap between the outer sheath 221 and the plug part 102, and finally through the outer sheath 221.

[0043] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0044] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
