Description

Technical Field

[0001] The utility model relates to the technical field of charging devices, and in particular to a plug-in charging device and a vehicle. Background Art

[0002] Currently, the charging cable of a DC charging gun is heavy, and there is a large resistance between the charging gun and the charging base. Especially outdoors in cold winter, the low temperature causes the charging cable to harden, making the resistance between the charging gun and the charging base even greater. Some vulnerable groups find it difficult to plug and unplug the charging gun when using it.

[0003] At present, there are mainly the following optimization methods for the plug-in and unplugging problem of the charging gun and the charging stand. For example, patent CN116131023A uses turbines and worms to increase torque and change the direction of rotation to achieve the role of auxiliary plug-in and unplugging. However, the application involves parts such as drive motors, turbines, and worms. The device structure is complex and the production cost is high. In addition, when there is no power supply in an emergency, the auxiliary plug-in fails. Patent CN116683237A can automatically retract when the charging gun is inserted through the coordination of structures such as the ball screw and ball screw sleeve, and automatically withdraw when the charging gun is pulled out after charging is completed. During the charging process, the ball screw can be self-locked, while reducing the use of the locking device. Through the coordination of structures such as the trigger blocking rod and the trigger slot plug, the insertion status of the charging gun can be automatically detected, and the ball screw can be driven in time, making the process smoother. However, the internal structure of the retraction cavity is complex, and the production process requirements are relatively high. Utility Model Content

[0039] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0040] It should be noted that the charging gun and the charging stand are devices used to charge electric vehicles. The existing technology includes plug-type charging guns and charging stands, as well as wireless charging technology.

[0041] Plug-type charging guns and charging docks are the current mainstream charging devices, with the advantages of high charging efficiency, fast charging speed, and relatively low cost. However, plug-type charging devices require manual operation, have disadvantages such as difficulty in plugging and unplugging, easy wear, and easy to be affected by harsh environments.

[0042] Wireless charging technology is an emerging technology in recent years. Its advantages are that it eliminates the need to plug and unplug the plug, which is convenient and fast, and can also reduce equipment wear and maintenance costs. However, wireless charging technology currently still has disadvantages such as low charging efficiency, high cost, and limited charging distance.

[0043] In general, the existing charging gun and charging stand technologies have certain limitations in terms of charging efficiency, cost and convenience, and require continuous technological innovation and improvement.

[0044] At present, the charging cable of the DC charging gun is heavy, and the resistance between the charging gun and the charging seat is large, especially in the cold winter outdoors, the low temperature causes the charging cable to harden, making the resistance between the charging gun and the charging seat even greater, and some vulnerable groups have difficulty plugging and unplugging the charging gun when using it. The utility model designs multiple grooves at the charging gun socket, and correspondingly arranges multiple rows of sliding balls in the charging seat body, so that users can plug and unplug the charging gun conveniently and labor-savingly, and improve the comfort of operation.

[0045] Combination Figures 1 to 4 As shown, according to a specific embodiment of the utility model, a plug-in charging device is provided.

[0046] Specifically, Figure 1 , Figure 4 As shown, a plug-in charging device includes: a charging seat 1, the charging seat 1 includes a plug-in slot 11 and a ball assembly 12, and the ball assembly 12 is movably arranged on the inner wall of the plug-in slot 11; a charging gun 2, the charging gun 2 is provided with an insertion portion 21, the insertion portion 21 is plugged and matched with the plug-in slot 11, and a matching portion 22 is provided on the outer periphery of the insertion portion 21, and the matching portion 22 is extended along the length direction of the insertion portion 21, and the matching portion 22 is arranged corresponding to the position of the ball assembly 12. When the charging gun 2 is inserted into the charging seat 1, part of the ball assembly 12 is located in the matching portion 22.

[0047] In this embodiment, a ball assembly 12 is arranged on the inner wall of the plug-in slot 11 of the charging seat body 1, and a matching portion 22 is arranged on the outer periphery of the insertion portion 21 of the charging gun 2. The matching portion 22 and the ball assembly 12 are arranged correspondingly, so that when the charging gun 2 is plugged and matched with the charging seat body 1, part of the ball assembly 12 is positioned and matched with the matching portion 22, and the matching portion 22 is extended along the length direction of the insertion portion 21, providing a larger matching space for the matching portion 22 and the ball assembly 12, facilitating the positioning and matching of the matching portion 22 and the ball assembly 12, preventing the charging gun 2 from falling out of the plug-in slot 11, and improving the connection reliability between the charging gun 2 and the charging seat body 1.

[0048] like Figure 2 , Figure 3As shown, the circumferential inner wall of the plug-in slot 11 is provided with a placement slot 111, and part of the ball assembly 12 is arranged in the placement slot 111. The ball assembly 12 includes a ball 121, and the ball 121 is movably arranged in the placement slot 111. Specifically, the placement slot 111 is arranged in the radial direction of the plug-in slot 11, and the ball assembly 12 is located in the placement slot 111. The ball assembly 12 is arranged along the radial direction of the plug-in slot 11. This arrangement enables the balls of the ball assembly 12 to be slidably connected with the matching portion 22 when the insertion portion 21 of the charging gun 2 is plugged into the plug-in slot 11 of the charging seat body 1, thereby preventing the charging gun 2 from falling out of the plug-in slot 11, thereby improving the connection reliability between the charging gun 2 and the charging seat body 1.

[0049] Furthermore, the ball assembly 12 also includes an elastic member 122, which is arranged in the placement groove 111, one end of the elastic member 122 abuts against the bottom end of the placement groove 111, and the other end of the elastic member 122 abuts against one side of the ball 121. Specifically, when the charging gun 2 is plugged into the charging seat 1, the ball 121 that enters the placement groove 111 after being pressed by the charging gun 2 will slide out of the placement groove 111 again under the drive of the elastic member 122, and part of the ball 121 is located in the matching portion 22 to position and match with the matching portion 22, preventing the charging gun 2 from escaping from the plug-in groove 11, thereby improving the connection reliability between the charging gun 2 and the charging seat 1. Such a setting can also provide a buffering and shock-absorbing effect for the ball assembly 12, so that the ball assembly 12 can be more stable and smooth during movement. The setting of the elastic member 122 can effectively absorb and disperse the impact and vibration force on the ball assembly 12, extend the service life of the ball assembly 12, and improve its performance and stability. At the same time, the provision of the elastic member 122 can also reduce the friction and wear between the ball assembly 12 and the mating portion 22, thereby reducing maintenance costs and improving the reliability of the overall equipment.

[0050] In this embodiment, the elastic member is configured as a spring, which may be a compression spring, a tension spring, etc. The embodiments of the elastic member are not limited thereto, and may also be a belt, common ones are rubber belts and metal belts, etc., or a rubber pad, common ones are rubber elastic pads and rubber shock absorbers, etc., or an elastic coupling and an elastic connecting plate, etc.

[0051] Furthermore, the ball assembly 12 is provided in plurality, the matching portion 22 is provided in plurality, and the matching portions 22 are provided in one-to-one correspondence with the ball assembly 12. In this way, more flexible matching and combination can be achieved, and the ball assembly 12 and the matching portion 22 can be replaced at any time as needed to adapt to different working requirements and environments. At the same time, the stability and reliability of the system can be improved, the possibility of failure can be reduced, and the work efficiency and production benefits can be improved. In addition, the one-to-one correspondence between the matching portions 22 and the ball assembly 12 can also improve the accuracy and precision of the system, ensuring product quality and production effect.

[0052] like Figure 4 As shown, the mating portion 22 is an arc groove. Specifically, the arc groove is extended along the length direction of the insertion portion 21, and a plurality of arc grooves are arranged at intervals along the circumference of the insertion portion. In this embodiment, the length of the arc groove is set equal to the length of the insertion portion 21. In other embodiments, the length of the arc groove can be adaptively changed. This arrangement can improve the stability and accuracy of the ball 121, making the ball 121 more stable and reliable during movement. The ball 121 is slidably connected to the arc groove to prevent the charging gun 2 from falling out of the plug-in slot 11, thereby improving the connection reliability between the charging gun 2 and the charging seat 1.

[0053] Furthermore, the diameter of the matching portion 22 is larger than the diameter of the ball 121. This arrangement facilitates the ball 121 to be embedded in the matching portion 22, that is, the surface of the ball 121 fits the surface of the matching portion 22, and when the charging gun 2 is plugged into the charging seat 1 for charging, part of the ball 121 is embedded in the matching portion 22.

[0054] Furthermore, the diameter of the ball 121 is smaller than or equal to the aperture of the placement groove 111. This arrangement prevents the ball 121 from slipping out of the placement groove 111, thereby improving the stability and reliability of the connection between the ball 121 and the matching portion 22.

[0055] like Figure 1 As shown, the charging seat 1 also includes a cover 13 and a shell 14. The shell 14 is provided with a plug slot 11. The cover 13 is movably connected to the outer wall of the shell 14. The cover 13 has an open state in which the plug slot 11 is opened, and a closed state in which the plug slot 11 is closed. In this way, the plug slot 11 inside the charging seat 1 can be protected to prevent dust or other debris from entering and affecting the use. At the same time, the movable connection design of the cover 13 also facilitates the user to open or close the plug slot 11 when using it, thereby improving the usability and safety of the charging seat 1.

[0056] Furthermore, the housing 14 includes a first housing 141 and a second housing 142. The first housing 141 is provided with the plug-in slot 11. The second housing 142 is provided along the circumference of the first housing 141. A connecting portion 143 movably connected to the cover 13 is provided on one side of the second housing 142. In this way, the housing 14 can be easily disassembled and replaced, and the plug-in slot 11 and the cover 13 can also be protected to extend their service life. In addition, the structural design of the first housing 141 and the second housing 142 can also improve the overall sealing and stability.

[0057] Specifically, the plug slot 11 is provided with a plurality of pins, which are usually made of metal and are used to connect the charger and the device for charging. The working principle of the pins is to use the conductive property of metal to transfer current from the charger to the device to achieve the charging function. The pins match the charging interface on the device and can firmly connect and transmit current, thereby completing the charging process.

[0058] According to another aspect of the present invention, a vehicle is provided, which is charged using a plug-in charging device, and the plug-in charging device is the above-mentioned plug-in charging device.

[0059] The pluggable charging device comprises: a charging seat body 1, the charging seat body 1 comprises a plug-in slot 11 and a ball assembly 12, and the ball assembly 12 is movably arranged on the inner wall of the plug-in slot 11; a charging gun 2, the charging gun 2 is provided with an insertion portion 21, the insertion portion 21 is plugged and matched with the plug-in slot 11, and a matching portion 22 is provided on the outer periphery of the insertion portion 21, and the matching portion 22 is extended along the length direction of the insertion portion 21, and the matching portion 22 is arranged corresponding to the position of the ball assembly 12. When the charging gun 2 is inserted into the charging seat body 1, part of the ball assembly 12 is located in the matching portion 22. By arranging a ball assembly 12 on the inner wall of the plug-in slot 11 of the charging seat body 1, and arranging a matching portion 22 on the outer periphery of the insertion portion 21 of the charging gun 2, the matching portion 22 and the ball assembly 12 are arranged correspondingly, so that when the charging gun 2 is plugged and matched with the charging seat body 1, part of the ball assembly 12 is positioned and matched with the matching portion 22, and the matching portion 22 is extended along the length direction of the insertion portion 21, providing a larger matching space for the matching portion 22 and the ball assembly 12, facilitating the positioning and matching of the matching portion 22 and the ball assembly 12, preventing the charging gun 2 from escaping from the plug-in slot 11, and improving the connection reliability between the charging gun 2 and the charging seat body 1.

[0060] When the user pulls out the gun for charging, the thumb presses the handle, and the sliding ball reduces the resistance between the charging gun and the charging seat, so the user can pull out the charging gun with a little force; when the user finishes charging and inserts the charging gun back into the charging seat, the arc groove designed for the charging gun is aligned with the charging seat. Thanks to the cooperation of the sliding ball and the arc groove, the user can insert the charging gun back into place with a little force. Compared with the current charging guns and charging seats on the market, the sliding ball and arc groove designed in this utility model will reduce the resistance during the process of plugging and unplugging the gun, making it more convenient for users to use.
