[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 7 The present invention provides a technical solution: an electric vehicle charging cable connection terminal, comprising a wall-mounted box 1, a connecting cable 11 arranged at the bottom of the wall-mounted box 1, and a charging gun 2 located at one end of the connecting cable 11, a touch panel is installed on the surface of the wall-mounted box 1, and a limit bracket 4 is provided on the movable card at the bottom of the charging gun 2, and the limit bracket 4 is used for auxiliary limit support of the charging gun 2;

[0030] A connection port 3 is installed at one end of the charging gun 2, and the connection port 3 is used to be clamped inside the charging port. A docking groove is opened on the side wall of the wall-mounted box 1, and the connection port 3 is clamped inside the docking groove. A dust shield frame 12 is installed on the side wall of the wall-mounted box 1, and the dust shield frame 12 is located directly above the charging gun 2. A pair of buffer blocks are installed on the inner wall of the dust shield frame 12, and the buffer blocks are against both ends of the charging gun 2. When the charging gun 2 is needed, it can be clamped in the connection port of the tram with the help of the connection port 3, and the anti-slip pressure plate 26 can play a supporting role to ensure the stability during the charging process. After charging is completed, the limit bracket 4 at the bottom of the charging gun 2 can be docked with the limit slot 13, which can reduce the accidental situation that the cable of the charging gun 2 is pulled and falls off from the wall-mounted box when the cables are messy in the subsequent process.

[0031] like Figure 3 As shown, during use, the charging gun 2 will be pulled and offset by external force, resulting in loosening or even falling off of the limit, which increases the management cost. A fixed handle 21 is installed at one end of the charging gun 2, and an anti-slip rubber pad is arranged inside the fixed handle 21. A positioning plate 22 is installed at the top of the charging gun 2. A clamping groove is provided at one end of the positioning plate 22 close to the fixed handle 21, and a movable wheel 25 is rotatably arranged inside the clamping groove. A limit stopper 24 is provided on one side of the movable wheel 25. The limit stopper 24 is movably clamped inside the clamping groove. The limit stopper 24 can be pressed against one end of the movable wheel 25 for limiting. A connecting shaft 23 is installed at one end of the charging gun 2. The connecting port 3 is arranged on one side of the connecting shaft 23, and a transmission belt 251 is movably clamped on the surface of the movable wheel 25. The transmission belt 251 passes through the connecting shaft 23 and the positioning plate 22 and is located on one side of the connecting port 3. When the charging gun 2 is stored in the clamping groove, the position of the movable wheel 25 can be adjusted so that the transmission belt 251 pulls the reset ring 31 to move, so that the expansion end block 27 and the anti-slip pressure plate 26 on one side are squeezed against each other. The anti-slip pressure plate 26 can be clamped on the inner wall of the docking groove during the storage limit process to play a supporting role, and the movable wheel 25 can be limited and clamped with the help of the limit block 24 to ensure the stability of the storage.

[0032] like Figure 3 As shown, in order to ensure that the connection port 3 will not be separated from the charging port of the electric vehicle due to external force during the subsequent charging process, or the rear end of the charging gun 2 is heavy and prone to instability during the charging process, a plurality of hinge grooves are provided on the side wall of the connecting shaft 23, and a hinge ball 261 is movably provided inside the hinge groove, and an anti-skid pressure plate 26 is installed at one end of the hinge ball 261. The cross-section of the anti-skid pressure plate 26 is "L"-shaped and fits on the corner of the connecting shaft 23. A rubber gasket is fixedly connected to the surface of the anti-skid pressure plate 26. The anti-skid pressure plate 26 can be movable and rest against the inside of the charging slot or the limit slot to play a supporting role, thereby ensuring the stability of charging.

[0033] like Figure 7As shown, an expansion end block 27 is provided on the edge of the connecting shaft 23. The expansion end block 27 is made of rubber and has a cavity inside. The expansion end block 27 is against the inner wall of the anti-skid pressure plate 26 to push the anti-skid pressure plate 26 to move. The expansion end block 27 can push the anti-skid pressure plate 26 to move under the squeezing action of the squeezing rod 33, so as to maintain stability during subsequent storage or charging.

[0034] like Figure 3 As shown, in order to reduce the wear of the edge due to accidents such as bumps during the continuous use of the charging gun 2, which affects the subsequent charging after plugging in, a reset ring 31 is movably sleeved on the surface of the connection port 3, and a plurality of extrusion rods 33 are installed at one end of the reset ring 31. The extrusion rods 33 are inserted inside the connecting shaft 23 and abut against the expansion end block 27. The reset ring 31 is used for protecting the outer wall of the connection port 3. A fixing ring 32 is fixedly connected to the surface of the reset ring 31. The fixing ring 32 is buckled with the transmission belt 251 and can be covered on the edge of the connection port 3 with the help of the reset ring 31. This can reduce the accidental loss of the connection port 3 during subsequent use and extend the service life of the charging gun 2.

[0035] like Figure 7 As shown, in order to reduce the situation where dirt adheres to the surface of the connection port 3 during use, a gap is provided between the reset ring 31 and the outer wall of the connection port 3, a plurality of elastic sheets are provided on the inner wall of the reset ring 31, and sponge gaskets are clamped between the elastic sheets for cleaning the outer wall of the connection port 3. When the charging gun 2 is plugged in and out of the charging port of the electric vehicle, the edge of the connection port 3 can be cleaned with the help of the sponge gasket to reduce the accidental situation of debris entering the charging port of the electric vehicle.

[0036] like Figure 5 and Figure 6 As shown, in order to reduce the distortion and swing of the charging gun 2 under the action of external force during use, which may cause it to fall off easily, a connecting plate 41 is provided at the top of the limiting bracket 4, and the connecting plate 41 is installed at the bottom of the connecting shaft 23. The limiting bracket 4 is movably clamped at the bottom of the connecting plate 41, and a compression shaft is installed inside the connecting plate 41, and one end of the compression shaft is clamped at the bottom of the connecting plate 41. A clamping shaft 42 is installed at one end of the limiting bracket 4, and the clamping shaft 42 is arranged parallel to the connecting plate 41. After charging is completed, the charging gun 2 can be clamped on one side of the wall-mounted box 1, and the docking shaft 43 can be inserted into the limiting slot 13, which can support the charging gun 2 at the top;

[0037] A plurality of docking shafts 43 are fixedly connected to the bottom of the clamping shaft 42, and a limiting slot 13 is provided on the side wall of the wall-mounted box 1. The position of the docking shaft 43 corresponds to the position of the limiting slot 13. A plurality of clamping slots are provided on the docking shaft 43. A plurality of limiting rods are installed inside the limiting slot 13, and the limiting rods can be clamped inside the clamping slots. Under the action of external force or in the process of pulling the connecting cable 11, the limiting bracket 4 at the bottom of the charging gun 2 can move on the connecting plate 41, and can make the charging gun 2 move within a certain range under the action of external force, and can play a buffering role to prevent the charging gun 2 from being squeezed and bumped against the inside of the docking slot of the wall-mounted box 1 when in the limited state, so as to reduce losses during use.

[0038] like Figure 6 As shown, in order to facilitate the use of the charging gun 2, a snap-in piece 44 is installed at the rear end of the docking shaft 43, and an anti-slip gasket is fixedly connected to the surface of the snap-in piece 44. The snap-in piece 44 can be clamped on the end cover of the charging port of the electric vehicle with the help of the snap-in piece 44, which plays a role of auxiliary limiting and can facilitate temporary storage during the charging process.

[0039] Working principle: First, when the charging gun 2 needs to be used, it can be clamped in the connection port of the tram with the help of the connection port 3, and the anti-slip pressure plate 26 can play a supporting role to ensure the stability during the charging process. After charging is completed, the limit bracket 4 at the bottom of the charging gun 2 can be docked with the limit slot 13, which can reduce the accidental situation that the charging gun 2 cable is pulled and falls off from the wall-mounted box in the case of subsequent cable clutter. When using the charging gun 2, the connection port 3 can be clamped in the charging port, and the reset ring 31 can be pushed to move on the connection port 3, so that the outer wall of the connection port 3 can be cleaned to reduce the adhesion of dirt during use.

[0040] Then, during the movement of the reset ring 31, the extrusion rod 33 and the expansion end block 27 can be squeezed, and the anti-skid pressure plate 26 can be expanded outward under the action of the expansion end block 27, so that the anti-skid pressure plate 26 is against the inside of the charging port of the electric vehicle, which can play a supporting role, increase the stability during use, and reduce the occurrence of unexpected situations;

[0041] Finally, after charging is completed, the charging gun 2 can be clamped on one side of the wall-mounted box 1, and the docking shaft 43 can be inserted into the limiting slot 13, which can support the charging gun 2 on the top, and under the action of external force or in the process of pulling the connecting cable 11, the limiting bracket 4 at the bottom of the charging gun 2 can move on the connecting plate 41, and can make the charging gun 2 move within a certain range under the action of external force, which can play a buffering role to prevent the charging gun 2 from being squeezed and bumped against the inside of the docking slot of the wall-mounted box 1 when in the limited state. In order to reduce the loss during use, and in the limiting process, the movable wheel 25 can be rotated, and the transmission belt 251 can pull the reset ring 31 to move. Under the action of the expansion end block 27 and the extrusion rod 33, the anti-slip pressure plate 26 can be pressed against the inside of the docking slot to play a supporting role to prevent displacement during the insertion process.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
