Description

Technical Field

[0001] This utility model relates to the field of charging pile plug technology, specifically a charging pile plug protection device. Background Technology

[0002] The charging plug is a key component used to connect electric vehicles to charging piles and realize the transmission of electrical energy. It is usually composed of conductive terminals, an insulating shell, a locking mechanism, etc. The conductive terminals are responsible for transmitting current, while the insulating shell plays a protective role and prevents electric shock. The insulating shell is made of high-temperature resistant and flame-retardant engineering plastics, which can withstand the high-temperature environment during the charging process and prevent the risk of leakage.

[0003] When using a charging plug, users often hold the plug and drag the cable. The pulling force is concentrated on the connection between the cable and the plug, which may directly tear the connection, causing the outer sheath to crack or the internal connection to fall off. Frequent dragging may cause the sealing structure at the connection to fail, allowing moisture and dust to seep into the charging plug and corrode it, leading to internal damage. To address this, we propose a charging plug protection device. Utility Model Content

[0006] The effect achieved by the above components is as follows: by setting up a protective structure, the connection between the cable and the charging plug is fixed by the pressure plate and the fixing plate, which disperses the pulling force when plugging, unplugging or dragging, avoids the pulling force acting directly on the connection, and prevents the outer sheath from cracking or the inside from falling off.

[0007] Preferably, the surface of the rectangular frame has two guide rods that slide through it, and both guide rods are fixedly connected to the pressure plate.

[0008] The aforementioned components achieve the following effect: the guide rod passes through the rectangular frame and is fixedly connected to the pressure plate, ensuring that the pressure plate remains stable during translation and preventing deviation.

[0009] Preferably, a number of protective strips are fixedly connected to the sides of the pressure plate and the fixing plate that are close to each other, and the protective strips are made of rubber.

[0010] The effect achieved by the above components is that the rubber protective strips on the pressure plate and fixing plate contact the cable, preventing the cable from being broken due to hard compression between the pressure plate and fixing plate and the cable.

[0011] Preferably, a turntable is fixedly connected to the end of the threaded rod away from the pressure plate, and the vertical cross section of the turntable is in the shape of a cross.

[0012] The effect achieved by the above components is that rotating the turntable drives the threaded rod to rotate, and the turntable facilitates the rotation of the threaded rod.

[0013] Preferably, the surface of the charging plug is provided with a shielding structure, the shielding structure includes a fixing frame, the fixing frame is fixedly connected to the surface of the charging plug, and a rubber cover is fixedly connected to the outer surface of the fixing frame.

[0014] The effect achieved by the above-mentioned components is that by setting up a shielding structure, the charging port can be covered when the vehicle is being charged, thereby preventing rainwater and dust from entering the charging port and thus providing protection during charging.

[0015] Preferably, two ropes are fixedly connected to one side of the rubber cover, and a pull ring is fixedly connected to the end of the rope away from the rubber cover.

[0016] The effect achieved by the above components is that the pull ring facilitates pulling the rope, which in turn facilitates pulling the rubber cover, thereby making it easier to open the rubber cover and preventing the rubber cover from obstructing the charging operation.

[0017] Preferably, hooks are fixedly connected to both sides of the charging plug, and the size of the hooks is adapted to the size of the pull ring.

[0018] The effect achieved by the above components is that the hook facilitates the pulling of the rubber cover after it is pulled, thereby avoiding the need to keep pulling the ring when inserting the charging plug into the charging port.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This utility model uses a protective structure to fix the connection between the cable and the charging plug by pressing the pressure plate and the fixing plate, dispersing the pulling force when plugging, unplugging or dragging, avoiding the pulling force acting directly on the connection, and preventing the outer sheath from cracking or the inside from falling off.

[0021] By setting up a shielding structure, the rubber cover is made of a flexible and elastic material. When the charging plug is charging, the rubber cover can bend and fit tightly against the surface of the vehicle, making it easy to cover the charging port when the vehicle is charging, thereby preventing rainwater and dust from entering the charging port and thus providing protection during charging.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-2This utility model provides a technical solution: a charging pile plug protection device, including a connector 2 installed on the surface of the charging plug 1, a cable 3 electrically connected to the surface of the charging plug 1, and a protective structure 4 on the surface of the charging plug 1. By setting the protective structure 4, the connection between the cable 3 and the charging plug 1 is fixed by the pressure plate 45 and the fixing plate 43, dispersing the pulling force during plugging, unplugging, or dragging, and preventing the pulling force from acting directly on the connection, thus preventing the outer sheath from cracking or the internal parts from falling off. The surface of the charging plug 1 is provided with a shielding structure 5, which facilitates the covering of the charging port when the vehicle is charging, thereby preventing rainwater and dust from entering the charging port, and thus providing protection during charging.

[0031] Reference Figure 2 and Figure 3 and Figure 4 As shown in this embodiment: the protective structure 4 includes two fixed arms 41, both of which are fixedly connected to the surface of the charging plug 1. A rectangular frame 42 is fixedly connected to the end of each fixed arm 41 away from the charging plug 1. A fixed plate 43 is fixedly connected to the inner wall of the rectangular frame 42. A threaded rod 44 is threaded through the surface of the rectangular frame 42. A pressure plate 45 is rotatably connected to the end of the threaded rod 44 near the fixed plate 43. Two guide rods 46 slide through the surface of the rectangular frame 42. Both guide rods 46 are fixedly connected to the pressure plate 45. The guide rods 46 pass through the rectangular frame 42 and are fixedly connected to the pressure plate 45 to ensure that the pressure plate 45 remains stable during translation and avoids displacement. Several protective strips 47 are fixedly connected to the side of the pressure plate 45 and the fixed plate 43 that are close to each other. The protective strips 47 are made of rubber. The rubber protective strips 47 on the pressure plate 45 and the fixed plate 43 contact the cable 3 to prevent the pressure plate 45 and the fixed plate 43 from forcibly squeezing the cable 3 and causing the cable 3 to break. A turntable 48 is fixedly connected to the end of the threaded rod 44 away from the pressure plate 45. The vertical cross section of the turntable 48 is in the shape of a cross. Rotating the turntable 48 causes the threaded rod 44 to rotate, and the turntable 48 facilitates the rotation of the threaded rod 44.

[0032] Reference Figure 5 and Figure 6As shown, specifically, the shielding structure 5 includes a fixed frame 51, which is fixedly connected to the surface of the charging plug 1. A rubber cover 52 is fixedly connected to the outer surface of the fixed frame 51. Two ropes 53 are fixedly connected to one side of the rubber cover 52. A pull ring 54 is fixedly connected to the end of the ropes 53 away from the rubber cover 52. The pull ring 54 facilitates pulling the ropes 53, thereby facilitating the pulling of the rubber cover 52 and preventing the rubber cover 52 from obstructing the charging operation. Hooks 55 are fixedly connected to both sides of the charging plug 1. The size of the hooks 55 is adapted to the size of the pull ring 54. The hooks 55 facilitate limiting the movement of the rubber cover 52 after it is pulled, thereby avoiding the need to keep pulling the pull ring 54 when the charging plug 1 is inserted into the charging port.

[0033] Working principle: Two fixing arms 41 are fixed to the surface of the charging plug 1. A fixing plate 43 and a threaded rod 44 are set in the rectangular frame 42 at their ends. When it is necessary to fix the cable 3, the rotating turntable 48 drives the threaded rod 44 to rotate. The threaded rod 44 pushes the pressure plate 45 to move towards the fixing plate 43. The guide rod 46 passes through the rectangular frame 42 and is fixedly connected to the pressure plate 45 to ensure that the pressure plate 45 remains stable when it moves horizontally and avoids displacement. The rubber protective strips 47 on the pressure plate 45 and the fixing plate 43 contact the cable 3 and generate friction through compression to clamp and fix the cable 3 between them. This avoids the pressure plate 45 and the fixing plate 43 from hard compression with the cable 3, which could cause the cable 3 to break. By pressing the pressure plate 45 and the fixing plate 43, the connection between the cable 3 and the charging plug 1 is fixed, dispersing the pulling force when plugging, unplugging or dragging, and avoiding the pulling force from acting directly on the connection, preventing the outer sheath from cracking or the inside from falling off.

[0034] The fixing frame 51 is fixed to the surface of the charging plug 1. The outer rubber cover 52 is made of a flexible material with elasticity. When the charging plug 1 is charging, the rubber cover 52 can bend and fit tightly against the surface of the vehicle by means of elasticity, thereby covering the charging port and preventing rainwater and dust from entering the charging port. The rope 53 and pull ring 54 on one side of the rubber cover 52 cooperate with the hooks 55 on both sides of the charging plug 1. When in use, pull the pull ring 54 to open the rubber cover 52 and hang it on the hook 55, so as to avoid the rubber cover 52 from obstructing the charging operation, thus making it easy to insert the charging plug 1 into the charging port.
