Description

Technical Field

[0001] This utility model belongs to the field of new energy vehicle technology, specifically relating to a charging interface for charging new energy vehicles. Background Technology

[0002] With social development and increased environmental awareness, the application of new energy sources has developed rapidly in recent years. Among the common new energy application products are new energy vehicles. New energy vehicles refer to automobiles that use unconventional vehicle fuels as a power source and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include four main types: hybrid electric vehicles, pure electric vehicles, fuel cell electric vehicles, and other new energy vehicles. Charging is a very important aspect of new energy vehicles, as it affects the user experience, range, and charging time.

[0003] Existing charging interfaces for new energy vehicles generally have a protective cover on their surface. The protective cover is usually connected to the interface mounting base by a connecting strap to prevent the protective cover from being lost. However, the length of the connecting strap cannot be adjusted. If the length is too long, the protective cover will swing, and if it is too short, it will affect the connection between the protective cover and the interface mounting base. Therefore, we propose a charging interface for new energy vehicles. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a charging interface for charging new energy vehicles, so as to solve the problem mentioned in the background art that the length of the connecting band of the existing new energy vehicle charging interface cannot be adjusted, that the length is too long and the protective cover will swing, and that the length is too short and the connection between the protective cover and the interface mounting base will be affected.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a charging interface for new energy vehicles, including an interface mounting base, an interface body fixedly connected to the surface of the interface mounting base, a protective cover rotatably connected to the surface of the interface body, the protective cover including a top cover, a body cover fixedly connected to the surface of the top cover, a rotating groove formed on the surface of the top cover, a limiting groove formed inside the rotating groove, a winding structure provided on the surface of the interface mounting base, the winding structure including a fixing box, a rotating rod rotatably connected inside the fixing box, coil springs fixedly connected to both ends of the rotating rod, a connecting strip fixedly connected to the surface of the rotating rod, a limiting ring fixedly connected to one end of the connecting strip, two sets of clamping structures symmetrically arranged on the surface of the interface mounting base, the clamping structure including a fixing plate, a sliding rod slidably connected to the surface of the fixing plate, a clamping ring fixedly connected to the top of the sliding rod, a limiting block fixedly connected to the bottom of the sliding rod, and a spring fixedly connected to the bottom of the limiting block.

[0006] Preferably, the surface of the cover is provided with threads, the inner surface of the interface body is provided with a threaded groove that matches the cover, and the surface of the interface body near the cover is provided with a rubber pad layer.

[0007] Preferably, one end of the coil spring is fixedly connected to the surface of the rotating rod, and the other end of the coil spring is fixedly connected to the inner wall of the fixed box.

[0008] Preferably, one end of the connecting strip is fixedly connected to the surface of the rotating rod, and the other end of the connecting strip is fixedly connected to the limiting ring. The connecting strip is wrapped around the surface of the rotating rod, and a square groove is formed on the surface of the fixing box. The connecting strip is slidably connected in the square groove.

[0009] Preferably, the connecting strip is slidably connected in the rotating groove, the limiting ring is rotatably connected in the limiting groove, and the width of the limiting groove is greater than the width of the rotating groove.

[0010] Preferably, the fixing plate is L-shaped, and a circular groove is formed on the surface of the fixing plate. The sliding rod is slidably connected in the circular groove, and the radius of the limiting block is larger than the radius of the sliding rod.

[0011] Preferably, the clamping ring is arc-shaped, and the surface of the clamping ring is in contact with the surface of the cover and the surface of the interface body. The two ends of the spring are respectively fixedly connected to the surface of the fixing plate and the surface of the interface mounting base.

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

[0013] 1. This charging interface for new energy vehicles is equipped with a protective cover and a winding structure. The cover is installed on the surface of the interface body through the cooperation of the cover body and the threaded groove. The connecting strip can be wound onto the surface of the rotating rod by a coil spring. At the same time, the other end of the connecting strip is connected to the limiting ring. The connecting strip and the limiting ring can rotate in the rotating groove and the limiting groove respectively. This ensures that when the cover is removed from the surface of the interface body by rotation, the connecting strip will not wrap around the surface of the cover. When the cover needs to be installed on the surface of the interface body, the connecting strip can be stretched. After loosening, the connecting strip is tightened by the coil spring so that the connecting strip is wound into the fixing box. When the cover is removed, the cover is tightened to one side of the fixing box by the coil spring to prevent the connecting strip from being too long or too short and affecting the use of the protective cover.

[0014] 2. The charging interface for new energy vehicles is equipped with a clamping structure. When the charging head is connected to the interface body, the limiting block is pushed by the spring, and then the clamping ring is moved by the sliding rod, so that the clamping ring abuts against the surface of the charging head and the interface body, thereby increasing the tightness of the connection between the charging head and the interface body and preventing the charging head and the interface body from slipping off during use.

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A charging interface for new energy vehicles includes an interface mounting base 1. An interface body 2 is fixedly connected to the surface of the interface mounting base 1. A protective cover 3 is rotatably connected to the surface of the interface body 2. The protective cover 3 includes a top cover 31, a body cover 32 is fixedly connected to the surface of the top cover 31, a rotating groove 33 is formed on the surface of the top cover 31, and a limiting groove 34 is formed inside the rotating groove 33. A winding structure 4 is provided on the surface of the interface mounting base 1. The winding structure 4 includes a fixing box 41, and a rotating rod 42 is rotatably connected inside the fixing box 41. The two ends of the rotating rod 42 are fixed... A coil spring 43 is fixedly connected to the surface of the rotating rod 42. A connecting strip 44 is fixedly connected to one end of the connecting strip 44. A limit ring 45 is fixedly connected to one end of the connecting strip 44. Two sets of clamping structures 5 are symmetrically arranged on the surface of the interface mounting base 1. The clamping structure 5 includes a fixing plate 51. A sliding rod 52 is slidably connected to the surface of the fixing plate 51. A clamping ring 53 is fixedly connected to the top of the sliding rod 52. A limit block 54 is fixedly connected to the bottom of the sliding rod 52. A spring 55 is fixedly connected to the bottom of the limit block 54. A protective cover 3 and a winding structure 4 are provided. The top of the cover 31 is connected to the cover body 32. The threaded groove is fitted onto the surface of the interface body 2. A coil spring 43 allows the connecting strip 44 to be wound around the surface of the rotating rod 42. Simultaneously, the other end of the connecting strip 44 is connected to a limiting ring 45. The connecting strip 44 and the limiting ring 45 can rotate within the rotating groove 33 and the limiting groove 34, respectively. This prevents the connecting strip 44 from wrapping around the surface of the cover 31 when it is removed from the surface of the interface body 2 by rotation. When the cover 31 needs to be installed on the surface of the interface body 2, the connecting strip 44 can be stretched. After loosening, the coil spring 43 tightens the connecting strip 44, ensuring a secure connection. The connecting strap 44 is wound inside the fixing box 41. When the cover 31 is removed, the cover 31 is tightened to one side of the fixing box 41 by the coil spring 43 to prevent the connecting strap 44 from being too long or too short and affecting the use of the protective cover 3. A clamping structure 5 is provided. When the charging head is connected to the interface body 2, the spring 55 pushes the limiting block 54, and then the sliding rod 52 drives the clamping ring 53 to move, so that the clamping ring 53 abuts against the surface of the charging head and the interface body 2, thereby increasing the tightness of the connection between the charging head and the interface body 2 and preventing the charging head and the interface body 2 from slipping off during use.

[0024] Furthermore, the surface of the cover 32 is provided with threads, and the inner surface of the interface body 2 is provided with a threaded groove that matches the cover 32. The surface of the interface body 2 near the cover 32 is provided with a rubber pad. The top cover 31 is installed on the surface of the interface body 2 through the cooperation of the cover 32 and the threaded groove. The rubber pad increases the sealing between the top cover 31 and the interface body 2, preventing dust and other debris from entering.

[0025] Furthermore, one end of the coil spring 43 is fixedly connected to the surface of the rotating rod 42, and the other end of the coil spring 43 is fixedly connected to the inner wall of the fixed box 41. When the rotating rod 42 rotates, the coil spring 43 causes the rotating rod 42 to have a tendency to return to its original position.

[0026] Furthermore, one end of the connecting belt 44 is fixedly connected to the surface of the rotating rod 42, and the other end of the connecting belt 44 is fixedly connected to the limiting ring 45. The connecting belt 44 wraps around the surface of the rotating rod 42. A square groove is provided on the surface of the fixing box 41. The connecting belt 44 is slidably connected in the square groove. When the connecting belt 44 is pulled, one end of the connecting belt 44 drives the rotating rod 42 to rotate, and the coil spring 43 deforms. In turn, the coil spring 43 makes the rotating rod 42 have a tendency to return to its original state. When the connecting belt 44 is not subjected to external force, the connecting belt 44 can be wound up on the surface of the rotating rod 42.

[0027] Furthermore, the connecting strip 44 is slidably connected in the rotating groove 33, and the limiting ring 45 is rotatably connected in the limiting groove 34. The width of the limiting groove 34 is greater than the width of the rotating groove 33. When the cover top 31 is installed and disassembled with the interface body 2 by rotating, the connecting strip 44 and the limiting ring 45 can rotate around the cover top 31 through the rotating groove 33 and the limiting groove 34, preventing the connecting strip 44 from getting tangled on the surface of the cover top 31.

[0028] Furthermore, the fixing plate 51 is L-shaped, and a circular groove is formed on the surface of the fixing plate 51. The sliding rod 52 is slidably connected in the circular groove. The radius of the limiting block 54 is larger than the radius of the sliding rod 52. The maximum moving distance of the sliding rod 52 is limited by the cooperation of the limiting block 54 and the circular groove, so as to prevent the sliding rod 52 from sliding out of the circular groove.

[0029] Furthermore, the clamping ring 53 is arc-shaped, and the surface of the clamping ring 53 is in contact with the surface of the cover 31 and the interface body 2. The two ends of the spring 55 are fixedly connected to the surface of the fixing plate 51 and the surface of the interface mounting base 1, respectively. The spring 55 keeps the clamping ring 53 pressed against the surface of the interface body 2, which increases the tightness of the connection between the charging head and the interface body 2 when the charging head is connected to the interface body 2, and prevents the charging head and the interface body 2 from slipping off during use.

[0030] Working principle: When in use, pull the connecting strap 44 outward. When the connecting strap 44 is pulled, one end of the connecting strap 44 drives the rotating rod 42 to rotate, and the coil spring 43 deforms. Then, the coil spring 43 makes the rotating rod 42 tend to return to its original position. Rotate to remove the cover 31. When the connecting strap 44 is not under external force, the connecting strap 44 can be rolled up on the surface of the rotating rod 42, thereby tightening the cover 31 on one side of the fixing box 41. This prevents the protective cover 3 from being lost when not in use, or the protective cover 3 from shaking and scratching the surface of the vehicle due to the connecting strap 44 being too long. When connecting the charging head to the interface body 2, the spring 55 pushes the limiting block 54, which in turn drives the clamping ring 53 to move through the sliding rod 52. This causes the clamping ring 53 to abut against the surface of the charging head and the interface body 2, thereby increasing the tightness of the connection between the charging head and the interface body 2 and preventing the charging head and the interface body 2 from slipping off during use.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
