Description

Technical Field

[0001] This utility model relates to the field of charging connection locking technology, specifically a safety connector for car charging piles with automatic locking function. Background Technology

[0002] Electric vehicles (BEVs) are powered by onboard power sources and driven by electric motors. Due to their relatively smaller environmental impact compared to traditional vehicles, their prospects are widely regarded as promising. Charging stations are used to charge electric vehicles. When the electric vehicle's power is insufficient, it connects to a charging station via a connector to achieve the charging function.

[0003] However, existing charging pile connectors, which connect the male and female ends via an embedded method, are prone to unreliable connections, leading to charging abnormalities. Some connectors also have mechanical latches, but these latches are inconvenient to open. To address this, a new car charging pile connector (see patent number: 201721339986.0) is provided, comprising a connector metal shell, a car, a charging pile, a second connector, and magnetic material. The connector metal shell is a hollow cavity, with a magnet surrounding its periphery. One end of the second connector has a recessed cavity, and the opening edge of the second connector has magnetic material. The other end of the second connector connects to the charging pile. One end of the connector metal shell connects to the car, and the other end of the connector metal shell is embedded in the recessed cavity of the second connector, with the magnet magnetically connected to the opening edge of the second connector. This invention not only effectively ensures a reliable connection and avoids charging abnormalities but also allows for convenient opening and closing.

[0004] However, some existing car charging pile safety connectors on the market use magnetic connection to lock the car charging head and the slot. However, the strength of the magnetic attraction cannot be guaranteed. If the magnetic attraction is too strong, it is difficult to open and close. Conversely, if the magnetic attraction is too weak, the connection cannot be guaranteed to be firm. During charging, the charging gun and the slot are prone to separation due to the loose connection, resulting in power outage during the charging process and affecting the charging effect.

[0005] To address the aforementioned issues, a safety connector for car charging stations with an automatic locking function has emerged. Utility Model Content

[0006] The purpose of this utility model is to provide a car charging pile safety connector with an automatic locking function to solve the problem that the charging gun and the slot will separate due to the loose connection during charging, resulting in power outage during the charging process and affecting the charging effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a safety connector for a car charging station with an automatic locking function, comprising a charging gun, a plug on one side of the charging gun, a locking component on the outside of the plug, a slot on the side of the plug away from the charging gun, and a protective shell on the outside of the slot.

[0008] The locking assembly includes a movable rod, with connecting rods at the top and bottom of one side of the movable rod. Two sets of connecting rods have locking blocks on the side away from the movable rod, and locking slots are provided on the outside of both sets of locking blocks. A spring is provided at the bottom of the middle position of both sets of connecting rods.

[0009] As a further improvement of this utility model, a push button is provided at the top of the moving rod.

[0010] As a further improvement of this utility model, both sets of connecting rods are elastically connected to the charging gun via springs.

[0011] As a further improvement of this utility model: a limiting hole is provided at the middle position of both sets of connecting rods, and a limiting rod is provided inside the limiting hole of both sets of limiting rods. Both sets of connecting rods are limitedly connected to the charging gun through the limiting rod and the limiting hole.

[0012] As a further improvement of this utility model, the charging gun is detachably connected to the protective shell through two sets of locking blocks and slots.

[0013] As a further improvement of this utility model, both the charging gun and the protective shell are made of polytetrafluoroethylene (PTFE) material.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the setting of a locking block and a slot, allows the user to hold the charging gun and insert the plug into the slot. At the same time, the top of the locking block moves downward through the inclined side of the slot, compressing the spring. When the locking block moves into the slot, it locks in place. This device can quickly and securely lock the charging gun to the car slot, preventing the plug from separating from the slot during charging and causing a power outage.

[0016] 2. This utility model, through the setting of a moving rod, a pressing button, a connecting rod, and a limiting rod, allows the charging gun to be removed when the charging work is completed by pressing the pressing button downwards. The pressing button drives the moving rod to descend, which in turn drives the two sets of connecting rods to move downwards and causes the two sets of locking blocks to descend, disengaging the locking blocks from the slots. This device is easy to separate and facilitates the reuse of the device in the future. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this utility model, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0023] like Figures 1 to 3 As shown, this utility model provides a car charging pile safety connector with automatic locking function, including a charging gun 1, a plug 3 on one side of the charging gun 1, a locking component 2 on the outside of the plug 3, a slot 4 on the side of the plug 3 away from the charging gun 1, and a protective shell 5 on the outside of the slot 4.

[0024] The locking assembly 2 includes a moving rod 201. Connecting rods 203 are provided at the top and bottom of one side of the moving rod 201. A locking block 205 is provided on the side of the two sets of connecting rods 203 away from the moving rod 201. A locking groove 206 is provided on the outside of the two sets of locking blocks 205. A spring 208 is provided at the bottom of the middle position of the two sets of connecting rods 203.

[0025] like Figures 1 to 3 As shown, a push button 202 is provided on the top of the moving lever 201.

[0026] In this embodiment, the push button 202 allows the operator to easily press the moving lever 201 to perform a separation operation, thus facilitating its use.

[0027] like Figures 1 to 3 As shown, both sets of connecting rods 203 are elastically connected to the charging gun 1 via springs 208.

[0028] In this embodiment, spring 208 is a mechanical part that works by utilizing elasticity. A part made of elastic material deforms under the action of external force and returns to its original shape after the external force is removed. It is also called a "spring" and is generally made of spring steel. There are many types of springs 208. According to their shape, they mainly include helical springs, spiral springs, leaf springs, and irregular springs. This embodiment mainly uses helical springs.

[0029] like Figures 1 to 3 As shown, each of the two sets of connecting rods 203 has a limiting hole 207 at the middle position, and each of the two sets of limiting holes 207 has a limiting rod 204 inside. Both sets of connecting rods 203 are limited to the charging gun 1 through the limiting rod 204 and the limiting hole 207.

[0030] In this embodiment, the limiting rod 204 and the limiting hole 207 can provide movement limiting when the connecting rod 203 moves, preventing the separation of the locking block 206 and the locking groove 206 during use, and ensuring the connection is firm.

[0031] like Figures 1 to 3 As shown, the charging gun 1 is detachably connected to the protective shell 5 via two sets of locking blocks 205 and locking slots 206.

[0032] In this embodiment, the above structure allows for quick locking and disassembly of the charging gun 1 and the charging slot, while also ensuring a secure connection, which facilitates operation.

[0033] like Figures 1 to 3 As shown, both the charging gun 1 and the protective shell 5 are made of polytetrafluoroethylene (PTFE).

[0034] In this embodiment, polytetrafluoroethylene (PTFE) material is used, which has the advantages of extremely low coefficient of friction, close to that of lubricating oil, corrosion resistance, high temperature resistance from -180°C to 260°C, and extremely high chemical stability.

[0035] The working principle of this utility model is as follows: When in use, hold the charging gun 1 and insert the plug 3 into the slot 4. At the same time, the top of the locking block 205 moves downward through the inclined side of the slot 206 and compresses the spring 208. When the locking block 205 moves into the slot 206, it locks and charges at the same time.

[0036] When the charging process is complete, press the button 202 down. The button 202 will cause the moving rod 201 to descend, and at the same time, it will cause the two sets of connecting rods 203 to move down and cause the two sets of locking blocks 205 to descend, so that the locking blocks 205 are disengaged from the slot 206, and the charging gun 1 can be removed.

[0037] The locking component 2 of this device can quickly lock the charging gun 1 and the car slot 4 in place, preventing the plug 3 from separating from the slot 4 during charging, which would cause a power outage and affect the charging effect. The separation operation is also relatively simple, making the device easy to use.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
