Description

Technical Field

[0001] This utility model relates to the field of battery cable connector technology, specifically a sealing and protection structure for electric vehicle battery cable connectors. Background Technology

[0002] Electric bicycles are a common mode of transportation. They are pure electric vehicles that are powered by batteries and driven by electric motors. When the battery is depleted, it needs to be charged. The charging method involves connecting the charger's charging head to the battery cable connector and then connecting the charger's plug to a household socket.

[0003] However, traditional battery cable connectors currently have certain limitations. Specifically, the sealing baffles used for sealing can easily obstruct the charging head, affecting the connection between the charging head and the connector. Furthermore, their sealing effect is not good enough and needs further improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a sealing and protection structure for electric vehicle battery cable connectors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sealing and protection structure for an electric vehicle battery cable connector includes a connector, a set of pins on the inner side of the connector, and supports on both sides of the outer side of the connector. A baffle is provided between the two supports. A storage groove is formed on the side of the baffle near the connector. A round rod is fixedly connected between the inner walls of the two sides of the storage groove. A set of racks is provided on the outer side of the round rod. A hidden cavity communicating with the outside is formed inside the connector and at the position corresponding to the round rod. A positioning block is hinged inside the hidden cavity. A first spring is fixedly connected between the positioning block and the inner wall of the hidden cavity. A pressure block is fixedly connected to the upper end of the positioning block. A sealing gasket is provided on the outer side of the connector at the position corresponding to the pins.

[0007] As a further embodiment of this utility model: a rotating shaft is hinged to the inner side of the support, one end of the rotating shaft is fixedly connected to the baffle, and a second spring is movably sleeved on the outer side of the rotating shaft, with the two ends of the second spring being fixedly connected to the outer edge of the rotating shaft and the inner wall of the support, respectively.

[0008] As a further improvement of this utility model, the lower end of the positioning block engages with the rack.

[0009] As a further improvement of this invention, the pressure block extends to the outside of the hidden cavity.

[0010] As a further improvement of this utility model, the axes of the round rod and the rotating shaft are horizontally aligned.

[0011] As a further improvement of this utility model: both sides of the connector are fixedly connected to side plates, and the side plates are provided with through holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By rotating the baffle counterclockwise, the round rod is driven to rotate counterclockwise, which in turn drives the rack to press the positioning block in sequence, so that the end of the positioning block is disengaged from the two adjacent racks, ensuring that the baffle can rotate normally. By using the first spring to push the end of the positioning block back and forth between the two adjacent racks, the angle of the baffle can be fixed easily, so as to prevent the baffle from moving down and obstructing the connection between the charging head and the connector.

[0014] 2. By pressing down on the positioning block, the positioning block is rotated counterclockwise, thereby releasing the restriction on the rack and rod as a whole, which in turn releases the restriction on the baffle, allowing the baffle to reset. Together with the sealing gasket, this achieves a good sealing effect on the joint. Attached Figure Description

[0019] Please see Figures 1-3In this embodiment of the present invention, a sealing and protection structure for an electric vehicle battery cable connector includes a connector 1. A set of pins 4 are arranged on the inner side of the connector 1, and supports 6 are arranged on both sides of the outer side of the connector 1. A baffle 7 is arranged between the two supports 6. A storage groove 14 is opened on the side of the baffle 7 near the connector 1. A round rod 12 is fixedly connected between the inner walls of the two sides of the storage groove 14. A set of racks 13 is arranged on the outer side of the round rod 12. A hidden cavity 9 communicating with the outside is opened inside the connector 1 at the position corresponding to the round rod 12. A positioning block 10 is hinged inside the hidden cavity 9. A first spring 11 is fixedly connected between the positioning block 10 and the inner wall of the hidden cavity 9. A pressure block 8 is fixedly connected to the upper end of the positioning block 10. A sealing gasket 5 is arranged on the outer side of the connector 1 at the position corresponding to the pins 4.

[0020] exist Figure 2 In the middle: a pivot 15 is hinged to the inner side of the support 6. One end of the pivot 15 is fixedly connected to the baffle 7, and a second spring 16 is movably sleeved on the outer side of the pivot 15. The two ends of the second spring 16 are fixedly connected to the outer edge of the pivot 15 and the inner wall of the support 6, respectively.

[0021] By adopting the above scheme, after the limit on the baffle 7 is released, the elasticity of the second spring 16 can be used to drive the rotating shaft 15 and the baffle 7 to rotate as a whole until the baffle 7 abuts against the sealing gasket 5, thereby facilitating the sealing protection of the joint 1.

[0022] exist Figure 3 In the middle: the lower end of the positioning block 10 meshes with the rack 13.

[0023] By adopting the above scheme, the positioning block 10 can be used to limit the rack 13 so as to fix the round rod 12 and the baffle 7 as a whole.

[0024] exist Figure 1 and 3 In the middle: the pressure block 8 extends to the outside of the hidden cavity 9.

[0025] By adopting the above scheme, the positioning block 10 can be rotated counterclockwise by pressing down the block 8, thereby releasing the overall restriction on the rack 13 and the round rod 12.

[0026] exist Figure 2 and 3 In the middle: the axes of the round rod 12 and the rotating shaft 15 are horizontally aligned.

[0027] By adopting the above solution, the baffle 7 can rotate axially normally.

[0028] exist Figure 1 In the middle: both sides of the connector 1 are fixedly connected to side plates 2, and the side plates 2 have through holes 3.

[0029] By adopting the above solution, it is convenient to install and fix the connector 1.

[0030] The working principle of this utility model is as follows: When it is necessary to charge the battery of an electric vehicle, firstly, the baffle 7 is rotated clockwise until the pin 4 is fully exposed. During this process, the rotating baffle 7 drives the round rod 12 and the rack 13 to rotate counterclockwise as a whole. At the same time, the counterclockwise rotating rack 13 presses the positioning block 10 in sequence, causing the end of the positioning block 10 to disengage from the two adjacent racks 13. Simultaneously, the first spring 11 pushes the end of the positioning block 10 back and forth between the two adjacent racks 13, thereby aligning the racks. The rack 13 and the round rod 12 are limited as a whole until the baffle 7 stops rotating, so that the angle of the baffle 7 can be fixed to prevent the baffle 7 from moving down and obstructing the connection between the charging head and the connector 1. When the charging is completed, the positioning block 10 is driven to rotate counterclockwise by pressing down the block 8, so as to release the limitation of the rack 13 and the round rod 12 as a whole. At this time, the second spring 16 drives the rotating shaft 15 and the baffle 7 to rotate counterclockwise as a whole until the baffle 7 abuts against the sealing gasket 5, so as to facilitate the sealing protection of the connector 1.

[0031] 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.
