Description

Technical Field

[0001] The utility model belongs to the technical field of new energy vehicles, and particularly relates to a charging line connector for new energy vehicles. Background Art

[0002] A new energy vehicle refers to a vehicle that uses new energy to replace traditional fuel. After long-term use, a new energy vehicle needs to go to a charging pile platform for energy supply, and the operator inserts the charging head into the vehicle charging port. However, when charging a new energy vehicle, it is impossible to ensure whether electric leakage will occur during the charging process. To avoid this phenomenon, a connector with an automatic power-off mechanism is used. Although the existing connector can cut off the power when electric leakage occurs, the separated charging wire is only fixed by a support plate, resulting in poor stability of the separated charging wire. Moreover, the existing connector lacks an alarm device, resulting in the inability of the vehicle owner and staff to handle problems in time, causing the powered-off vehicle to occupy the charging pile for a long time and wasting resources. Content of the Utility Model

[0003] The utility model provides a charging line connector for new energy vehicles to solve the problems raised in the above background art.

[0004] To achieve the above object, the utility model provides the following technical solution: A charging line connector for new energy vehicles, including an outer shell one, an outer shell two, a socket and a buffer pad, further including a sleeve, a first fixing mechanism and a second fixing mechanism.

[0020] Please refer to Figures 1-5 , the present utility model provides the following technical solutions: A charging cable connector for a new energy vehicle, including a first housing 1, a second housing 2, a socket 4 and a buffer pad 7, further including a sleeve 3, a first fixing mechanism 5 and a second fixing mechanism 6. An alarm 21 and a trigger 22 are installed on the second housing 2. Matching sockets 4 and plugs 41 are respectively installed on the first housing 1 and the second housing 2. The sleeve 3 is penetrated by the socket 4 and installed on the first housing 1 through a first spring 33. A light strip 31 is installed on the side wall of the sleeve 3. Several second fixing blocks 61 are installed on the side wall groove of the second housing 2 through a third spring 62. A groove matching with the tip of the second fixing block 61 is provided on the side wall of the sleeve 3;

[0021] The first fixing mechanism 5 includes an electric telescopic rod 51, a first fixing block 52, a second spring 53, a fixing groove 54 and an unlocking groove 55. Several first fixing blocks 52 are installed on the second housing 2 through a second spring 53. A triangular prism is installed at the top of the first fixing block 52. A fixing groove 54 matching with the first fixing block 52 is provided on the side wall of the first housing 1. A protrusion is provided at the other end of the first fixing block 52. An unlocking groove 55 is opened on the protrusion of the first fixing block 52. An electric telescopic rod 51 matching with the unlocking groove 55 is installed on the second housing 2.

[0022] The matching part of the plug 41 and the socket 4 can be wrapped by the cooperation of the shell 1 and the shell 2 2 to prevent the connection part of the plug 41 and the socket 4 from being exposed to the outside world. The sleeve 3 can wrap the socket 4 to prevent the socket 4 from being directly exposed to the outside world. The sleeve 3 is installed on the shell 1 through the spring 1 33 to ensure that when the user installs the socket 4 on the plug 41, the sleeve 3 will not hinder the movement of the shell 1, thereby ensuring the working effect of the device. The sleeve 3 can be fixed to the shell 2 2 by the cooperation of the fixing block 2 61 and the side wall groove of the sleeve 3 to ensure that when the matching between the shell 1 and the shell 2 2 is released, the sleeve 3 is still installed on the shell 2 2 to prevent the shell 1 from falling directly to the ground after the fixing between the shell 1 and the shell 2 2 is released, thereby preventing the shell 1 from being damaged. At the same time, the sleeve 3 can also prevent the socket 4 and the plug 41 from being exposed to the outside world. By setting a plurality of fixing blocks 2 61, the working effect of the second fixing mechanism 6 is ensured. The shape of the tip of the fixing block 2 61 ensures that the sleeve 3 can push the fixed block 2 61 in the process of entering and exiting the shell 2 2, which is convenient for users to install and remove the sleeve 3. When the fixed block 2 61 moves, the spring 3 62 is compressed. When the force applied by the sleeve 3 to the fixed block 2 61 disappears, the fixed block 2 61 can return to its original position under the action of the spring 3 62, ensuring the working effect of the fixed block 2 61. When leakage occurs during charging, the trigger 22 will be activated. At this time, the trigger 22 will control the device to release the fixation of the first fixing mechanism 5 on the shell 1. The shell 1 and the shell 2 2 are quickly separated under the action of the spring 1 33. At this time, the socket 4 and the plug 41 are separated, and the device is powered off to avoid safety accidents. When the trigger 22 is triggered, the alarm 21 will send a signal to the outside world to remind the owner and the staff of the leakage phenomenon, so that the staff and the owner can deal with the problem in time. The color of the light strip 31 is a bright color. After the shell 1 and the shell 2 2 are separated, the light strip 31 can remind outsiders that the device is in a power-off state;

[0023] The outer shell 1 can be fixed on the outer shell 2 through the cooperation of the first fixing block 52 and the fixing groove 54. The inclined surface of the triangular prism provided on the first fixing block 52 faces the outer shell 1. During the process of the outer shell 1 and the outer shell 2 coming into contact, the side wall of the fixing groove 54 can push against the first fixing block 52, ensuring that there is no obstruction during the process of the user installing the outer shell 1 onto the outer shell 2. After the first fixing block 52 enters the fixing groove 54, the cooperation between the vertical side wall of the triangular prism and the side wall of the fixing groove 54 ensures the stability of the cooperation between the first fixing block 52 and the fixing groove 54. The second spring 53 ensures that the first fixing block 52 can quickly return to its original position after moving, ensuring the working effect of the first fixing block 52. The tip of the electric telescopic rod 51 has an inclined surface. When the electric telescopic rod 51 extends, the first fixing block 52 can be pushed through the cooperation of the electric telescopic rod 51 and the unlocking groove 55, releasing the cooperation between the first fixing block 52 and the fixing groove 54, thereby realizing the release of the fixation between the outer shell 1 and the outer shell 2. When the trigger 22 is triggered, the trigger 22 will control the electric telescopic rod 51 to extend, realizing the release of the fixation between the outer shell 1 and the outer shell 2. After the fixation is released, the outer shell 1 and the outer shell 2 will separate under the action of the first spring 33, realizing the automatic separation of the outer shell 1 and the outer shell 2 when the device has a leakage phenomenon.

[0024] Specifically, a support rod penetrating the first fixing block 52 is provided on the side wall of the groove of the outer shell 2 for installing the first fixing block 52.

[0025] The support rod penetrating the first fixing block 52 ensures the stability of the first fixing block 52 during the moving process. The second spring 53 is installed outside the support rod penetrating the first fixing block 52, avoiding the deviation of the second spring 53 during the compression process and ensuring the stability of the connection between the second spring 53 and the outer shell 2 and the first fixing block 52.

[0026] Specifically, a baffle 32 is hinged to the port of the sleeve 3 through a torsion spring shaft, and a protrusion is provided on the side wall of the port of the sleeve 3.

[0027] The baffle 32 can seal the port of the sleeve 3, ensuring the sealing performance of the sleeve 3. The baffle 32 is installed on the torsion spring shaft, ensuring that the moved baffle 32 can quickly return to its original position, eliminating the need for the user to manually restore the baffle 32 to its original state. The protrusion at the port of the sleeve 3 can prevent the baffle 32 from rotating outward from the sleeve 3, playing a limiting role and avoiding the baffle 32 rotating too large an angle under the action of the torsion spring shaft, resulting in the influence on the working effect of the baffle 32.

[0028] Specifically, the length of the baffle 32 is less than the distance between the torsion spring shaft of the baffle 32 and the socket 4 after the socket 4 and the plug 41 are engaged.

[0029] During the process of the user installing the socket 4 onto the plug 41, the plug 41 can push the baffle 32 into the interior of the sleeve 3, and the length of the baffle 32 ensures that the baffle 32 does not obstruct the mating of the socket 4 and the plug 41.

[0030] Specifically, when the sleeve 3 is installed on the outer shell two 2, the position where the light strip 31 is set is on the part of the sleeve 3 outside the outer shell two 2. Inductive sheets 34 are provided on the side wall grooves of the sleeve 3 and the grooves of the outer shell one 1.

[0031] The position where the light strip 31 is set ensures that when the outer shell one 1 and the outer shell two 2 are separated, the light strip 31 is exposed to the external environment, ensuring the working effect of the light strip 31. When the fixed block two 61 and the inductive sheet 34, and the side wall protrusion of the sleeve 3 and the inductive sheet 34 provided on the groove of the outer shell one 1 are not in contact, the light strip 31 is in an untriggered state. When the outer shell one 1 and the outer shell two 2 are separated, the inductive sheet 34 provided on the side wall protrusion of the sleeve 3 and the groove of the outer shell one 1 comes into contact, and at this time the light strip 31 lights up, ensuring the working effect of the light strip 31. The starting method of the light strip 31 reduces the power consumption, reduces the usage duration of the light strip 31, and extends the service life of the light strip 31.

[0032] Specifically, there are protrusions on the side wall of the sleeve 3, and there are grooves on the side wall of the groove of the outer shell one 1 for installing the sleeve 3 that cooperate with the side wall protrusions of the sleeve 3. Buffer pads 7 are provided on the side wall grooves of the side wall protrusion of the sleeve 3 and the groove of the outer shell one 1. There are protrusions on the side wall of the part of the socket 4 passing through the sleeve 3, and buffer pads 7 are installed on the side wall protrusions of the socket 4.

[0033] The cooperation between the side wall protrusion of the sleeve 3 and the side wall grooves of the groove of the outer shell one 1 for installing the sleeve 3 ensures the stability of the sleeve 3 during the movement process. The cooperation between the side wall protrusion of the sleeve 3 and the side wall grooves of the groove of the outer shell one 1 for installing the sleeve 3, and the side wall protrusion of the socket 4 and the sleeve 3 plays a limiting role, preventing the sleeve 3 from detaching from the outer shell one 1 during the movement under the action of the first spring 33, which may affect the working effect of the sleeve 3. The buffer pads 7 reduce the impact when the sleeve 3 comes into contact with the side walls of the side wall protrusions of the socket 4 and the side wall grooves of the groove of the outer shell one 1, ensuring the stability of the sleeve 3 and extending the service life of the sleeve 3.

[0034] Specifically, there are protrusions on the side wall of the fixed block two 61, and grooves are provided on the side wall of the slot of the outer shell two 2 for installing the fixed block two 61 that cooperate with the side wall protrusions of the fixed block two 61.

[0035] The cooperation between the side wall protrusions of the fixed block 61 and the side wall grooves of the groove for installing the fixed block 61 in the outer shell 2 ensures the stability of the fixed block 61 during movement. The cooperation between the side wall protrusions of the fixed block 61 and the side wall grooves of the groove for installing the fixed block 61 in the outer shell 2 also plays a limiting role, preventing the fixed block 61 from separating from the side wall grooves of the outer shell 2, thereby ensuring the stability of the fixed block 61.

[0036] The working principle and use process of the utility model are as follows: when charging, the sleeve 3 is installed on the shell 2. When the sleeve 3 enters the groove of the shell 2, the fixing block 2 61 is pushed. As the sleeve 3 moves, the fixing block 2 61 enters the inside of the side wall groove of the sleeve 3 under the action of the spring 3 62, so that the second fixing mechanism 6 fixes the sleeve 3. The shell 1 continues to be moved. When the shell 1 contacts the shell 2, the shell 1 pushes the fixing block 52. The moved fixing block 52 enters the fixing groove 54. Then the fixing block 52 returns to its original position under the action of the spring 2 53. The shell 1 and the shell 2 are installed together through the cooperation of the fixing block 52 and the fixing groove 54. When the shell 1 and the shell 2 are installed together, the plug 41 pushes the baffle 32, and the pushed baffle 32 releases the seal on the sleeve 3. The sleeve 3 starts to move under the push of the shell 2, the plug 41 and the socket 4 approach each other, and after the shell 1 is installed on the shell 2, the socket 4 and the plug 41 are installed together, and charging starts. When leakage occurs, the trigger 22 is triggered. The triggered trigger 22 controls the electric telescopic rod 51 to extend. During the extension of the electric telescopic rod 51, the fixed block 52 will be pushed, and the cooperation between the fixed block 52 and the fixed groove 54 will be released, and the spring 33 returns to its original state. The shell 1 and the shell 2 are separated under the action of the spring 33, the socket 4 and the plug 41 are separated, and the device is powered off. At the same time, the alarm 21 sends a signal to the outside world to remind the owner and the manager of the leakage. After the shell 1 and the shell 2 are separated, the fixed block 61 and the sleeve 3 are in contact with the induction sheet 34, and the light strip 31 lights up, reminding that the device is in a power-off state.
