[0001] The utility model relates to the technical field of new energy vehicle charging plugs, in particular to a new energy vehicle charging plug anti-dropping device. Background Art

[0002] The vehicle charging port is a dedicated interface used by new energy vehicles to connect to charging equipment to recharge the vehicle's power battery. This interface is used in various types of new energy vehicles, including plug-in hybrid vehicles, extended-range electric vehicles, and pure electric vehicles. Through this interface, the vehicle can use an external power source to charge the battery, thereby replenishing energy and supporting the vehicle's electric drive system.

[0003] After extensive searching, the publication number CN221552333U discloses a device for preventing the charging plug of a new energy vehicle from falling off. This device relates to the technical field of charging plugs for new energy vehicles. During the charging operation, the limit blocks will be inserted into the grooves on both sides of the vehicle's charging socket to fix the charging plug as a whole, effectively preventing the charging plug from falling off and improving the stability during charging insertion.

[0004] In the existing new energy vehicle charging technology, although the positioning of the charging plug has been achieved to prevent the plug from falling off during the charging process, the operation of unplugging the charging plug is still not convenient enough. In the above technology, the user needs to operate with both hands: that is, one hand holds the handle and the other hand pushes the dial block forward along the slide groove. Only with this two-handed coordinated operation can the charging plug be unplugged. This design has certain inconveniences in actual operation and affects the efficiency of removing the plug. Therefore, a new energy vehicle charging plug anti-dropping device is needed to solve the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide a new energy vehicle charging plug anti-dropping device, which has the advantage of improving the convenience of operation when the plug is pulled out, and solves the problem in the prior art that when the plug is in a limited position, two hands are required to remove the plug, thus causing inconvenience in operation.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a device for preventing a new energy vehicle charging plug from falling off, comprising a housing, a plug connector being embedded in the front end of the housing, a limit frame being movably mounted on the top of the housing, and the limit frame being movably mounted to the housing via a limit assembly;

[0007] The housing comprises two sealed shells, each having a groove for installing a limit frame on the top of one side opposite to the other, and a limit rod fixedly installed on the front end of one side opposite to the other;

[0008] The limiting assembly includes a first connecting rod and a second connecting rod. There are two first connecting rods, and the two first connecting rods are respectively fixedly mounted on the outer walls of the two sealing shells. The two first connecting rods are respectively elastically connected to the second connecting rods through limiting springs, and the second connecting rod is fixedly mounted at the rear end of the limiting frame.

[0009] Preferably, a sealing sleeve is installed at the rear end of the housing, which securely connects the rear ends of the two sealed shells via the sealing sleeve, through which electrical wires pass. In this design, the rear ends of the housings are connected, allowing the rear ends of the two sealed shells to be securely connected via the sealing sleeve. This design not only enhances the overall structural stability of the device, but also ensures the safety and reliability of the electrical connection by allowing the wires to pass through the sealing sleeve, while also facilitating maintenance and replacement of the wires.

[0010] Preferably, a sealing plate is fixedly mounted on the rear end of the plug connector. Its two sides contact the inner walls of the two sealed shells, but are not fixedly connected. The wires pass through the housing below the sealing plate. In this design, a sealing plate is fixedly mounted on the rear end of the plug connector. Its two sides contact the inner walls of the two sealed shells, but are not fixedly connected.

[0011] Preferably, the two sealed housings are separated on opposite sides by a sealing plate, have matching dimensions, and are securely connected by mounting screws. This design ensures a tight fit between the sealed housings, improving the sealing performance of the entire device and preventing the intrusion of dust and moisture, thereby protecting the internal electrical components and extending the device's service life.

[0012] Preferably, a pressing groove is provided at the top rear end of the limit frame, and anti-slip grooves are provided in the pressing groove. A cavity is provided inside the limit frame, and a through-type reserved hole is provided on the limit frame, and the limit rod passes through the reserved hole, and the limit frame is rotatably connected to the shell along the limit rod. In the design, a pressing groove is provided at the top rear end of the limit frame, and anti-slip grooves are provided therein, which not only provides a good operating feel but also increases the safety of operation. The cavity design inside the limit frame and the opening of the through-type reserved hole enable the limit rod to pass through the reserved hole. Such a structural design enables the limit frame to be rotatably connected to the shell along the limit rod, providing a flexible limiting function.

[0013] Preferably, the second connecting rod passes through the rear end of the limit frame and is fixedly connected to the limit frame. The second connecting rod has a slot into which the end of the limit spring facing away from the first connecting rod is inserted. In this design, the second connecting rod passes through the rear end of the limit frame and is fixedly connected to the limit frame. The slot allows the end of the limit spring facing away from the first connecting rod to be inserted.

The pressing groove is provided with anti-slip grooves, which not only provides a good hand feel, but also increases the friction during user operation, making the pressing operation more stable and accurate, and reducing operational failures caused by hand slippage. By designing the limit frame and the limit assembly as movable installations, the structure of the entire device is simplified, the connection between the various components is made more compact, and unnecessary space occupation is reduced. At the same time, the entire device is also made lighter and easier for users to operate, achieving the effect of improving the convenience of operation when the plug is pulled out.

[0024] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figures 1 to 5 As shown, the present invention provides an embodiment: a new energy vehicle charging plug anti-drop device, comprising a housing 5, a plug connector 1 embedded in the front end of the housing 5, a limit frame 2 movably mounted on the top of the housing 5, and the limit frame 2 movably mounted on the housing 5 through a limit assembly 3;

[0027] The housing 5 includes two sealed shells 51. The tops of the two sealed shells 51 on opposite sides are provided with grooves for mounting the limit frame 2. The front ends of the two sealed shells 51 on opposite sides are fixed with limit rods 52.

[0028] The limiting assembly 3 includes a first connecting rod 31 and a second connecting rod 33. There are two first connecting rods 31. The two first connecting rods 31 are respectively fixedly mounted on the outer walls of the two sealing shells 51. The two first connecting rods 31 are respectively elastically connected to the second connecting rod 33 through a limiting spring 32. The second connecting rod 33 is fixedly mounted at the rear end of the limiting frame 2.

[0029] Specifically, a pressing groove 21 is provided at the top rear end of the limit frame 2. The user can press this groove to release the lock between the limit frame 2 and the charging pile interface. This design allows the user to operate it with one hand, eliminating the need for two hands to work together like traditional designs, where one hand holds the handle and the other hand pushes the dial, thus greatly improving the convenience of operation.

[0030] The limit assembly 3 consists of a first connecting rod 31 and a second connecting rod 33, which are elastically connected by a limit spring 32. This elastic connection not only provides a stable limiting effect, but also, when releasing the limit, the elastic effect of the spring can help the user move the limit frame 2 more easily, reducing the operating force. At the same time, the limit frame 2 is rotatably connected to the housing 5 along the limit rod 52. This design allows the limit frame 2 to move within a certain angle range. The user only needs to apply a small amount of force to achieve the rotation of the limit frame 2, thereby unlocking the charging plug. The pressing groove 21 is provided with anti-slip grooves, which not only provides a good hand feel, but also increases the friction during user operation, making the pressing operation more stable and accurate, and reducing operation failures caused by hand slippage. By designing the limit frame 2 and the limit assembly 3 as a movable installation, the structure of the entire device is simplified, the connection between the various components is made more compact, and unnecessary space occupation is reduced. At the same time, the entire device is also made lighter and easier for the user to operate, achieving the effect of improving the convenience of operation when unplugging the plug.

[0031] Example 2

[0032] In order to improve the sealing of the device during use and avoid damage to the wires during unlocking or locking operations, Figure 1 and Figure 2 As shown, in this embodiment, the rear end of the housing 5 is connected and installed with a sealing sleeve 4. The rear ends of the two sealed shells 51 are fixedly connected through the sealing sleeve 4, and the wires pass through the sealing sleeve 4. In this design, the rear end of the housing 5 is connected and installed with the sealing sleeve 4, so that the rear ends of the two sealed shells 51 are fixedly connected through the sealing sleeve 4. This design not only enhances the overall structural stability of the device, but also the design of the wires passing through the sealing sleeve 4 ensures the safety and reliability of the electrical connection, while also facilitating the maintenance and replacement of the wires.

[0033] Furthermore, a sealing plate 11 is fixedly mounted on the rear end of the plug connector 1. Its two sides contact the inner walls of the two sealed shells 51, but are not permanently connected. The wires pass through the housing 5 below the sealing plate 11. In this design, the sealing plate 11 is fixedly mounted on the rear end of the plug connector 1. Its two sides contact the inner walls of the two sealed shells 51, but are not permanently connected. This design allows the wires to pass through the housing 5 below the sealing plate 11, ensuring a sealed electrical connection while providing sufficient flexibility, making the device more convenient during installation and use.

[0034] Furthermore, the two sealed housings 51 are separated on opposite sides by a sealing plate 11. The two sealed housings 51 are sized to match and are securely connected by mounting screws. This design ensures a tight fit between the two sealed housings 51, improving the sealing performance of the entire device and preventing the intrusion of dust and moisture, thereby protecting the internal electrical components and extending the device's service life.

[0035] Example 3

[0036] In order to facilitate the user to open and close the limit frame with one hand, and to quickly disassemble the device in case of failure, Figure 3 、 Figure 4 and Figure 5 As shown, in this embodiment, a pressing groove 21 is provided at the top rear end of the limit frame 2, and anti-slip grooves are provided in the pressing groove 21. A cavity 23 is provided inside the limit frame 2. A through-type reserved hole 22 is provided on the limit frame 2, and the limit rod 52 passes through the reserved hole 22. The limit frame 2 is rotatably connected to the shell 5 along the limit rod 52. In the design, a pressing groove 21 is provided at the top rear end of the limit frame 2, and anti-slip grooves are provided therein, which not only provides a good operating feel, but also increases the safety of the operation. The design of the cavity 23 inside the limit frame 2 and the opening of the through-type reserved hole 22 enable the limit rod 52 to pass through the reserved hole 22. Such a structural design enables the limit frame 2 to be rotatably connected to the shell 5 along the limit rod 52, providing a flexible limiting function.

[0037] Furthermore, a second connecting rod 33 passes through the rear end of the limit frame 2 and is fixedly connected to the limit frame 2. A slot 301 is defined in the second connecting rod 33, into which the end of the limit spring 32 facing away from the first connecting rod 31 is inserted. In this design, the second connecting rod 33 passes through the rear end of the limit frame 2 and is fixedly connected to the limit frame 2. The slot 301 defined in the second connecting rod 33 allows the end of the limit spring 32 facing away from the first connecting rod 31 to be inserted. This design simplifies the spring installation process while ensuring the spring's stability and reliability, providing effective elastic support for the limit frame 2.

[0038] Furthermore, the limit spring 32 is designed using a compression spring material, and the end of the limit spring 32 facing away from the second connecting rod 33 is welded to the first connecting rod 31. This design not only ensures the strength and durability of the spring, but also provides a more secure fixation through welding, ensuring the stability of the spring during long-term use, thereby ensuring the reliability and durability of the entire charging plug anti-disconnection device.

[0039] When using the present invention, align the plug connector 1 with the charging interface of the new energy vehicle, and push the limit frame 2 forward by pressing the pressing groove 21 at the top rear end of the limit frame 2 until the limit frame 2 is locked with the charging pile interface, thereby realizing the operation of inserting the plug connector 1 into the charging interface of the new energy vehicle. At this time, the charging process will start automatically. To confirm the charging status, you can check it through the vehicle's dashboard or the display screen of the charging pile. After charging is completed, press the pressing groove 21 on the limit frame 2 to make the limit frame 2 rotate along the positioning rod, thereby releasing the lock of the limit frame 2 and the charging pile interface, and thus pulling out the plug connector 1. During this operation, it can be operated with one hand. For normal use of the above operation, the elasticity of the limit spring 32 needs to be checked regularly to ensure its normal operation.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
