Description

Technical Field

[0001] This utility model relates to the field of interface technology, and in particular to a quick-change interface for electric vehicle batteries that prevents mis-insertion. Background Technology

[0002] The electric vehicle battery interface refers to the physical interface through which an electric vehicle connects to an external power source to charge its battery. The design of this interface varies depending on the brand, model, and charging standard of the electric vehicle.

[0003] Patent CN216488655U discloses a connector interface assembly for an electric vehicle charger. It includes a first base and multiple pins positioned on the first base. The interface includes a second base and multiple terminals positioned on the second base for holding the pins. The second base has a slot that matches the outer contour of the first base. When using this patent, the interface is installed on the electric vehicle, the connector is connected to the power supply using a connecting cable, and then the connector is inserted into the interface. However, this existing patent lacks a locking function, making it easy for the connector to detach from the interface due to accidental contact or external factors. This not only affects the charging effect but can also damage the charging equipment or even cause safety accidents.

[0004] Therefore, there is a need to provide a quick-change interface for electric vehicle batteries with a locking function to prevent misinsertion. Utility Model Content

[0005] In order to overcome the shortcomings of the existing patents, which lack a locking function and are prone to detachment from the interface due to accidental contact or external factors, thus affecting the charging effect, damaging the charging equipment, or even causing safety accidents, this utility model provides a quick-change interface for electric vehicle batteries with a locking function to prevent misinsertion.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a quick-change interface for electric vehicle batteries that prevents mis-insertion, comprising a first interface, a protective cover, a second interface, and a connecting wire. The protective cover is hinged to the first interface, and the connecting wire is provided on the second interface. The interface also includes a plug, a mounting base, guide rods, sliding plates, a locking block, an elastic element, a connecting plate, and a protective shell. The first interface has a plug, the second interface has a protective shell, and the second interface has a mounting base. Two guide rods are fixedly connected to the mounting base. A connecting plate is slidably disposed within the protective shell, sliding on the two guide rods. An elastic element is sleeved on each guide rod, with both ends of the elastic element connected to the guide rod and the connecting plate, respectively. Two sliding plates are fixedly connected to the connecting plate, and a locking block is fixedly connected between the two sliding plates, locking into the mounting base.

[0007] Preferably, the assembly also includes a mounting sleeve, a magnet, a first fixing seat, a second fixing seat, and bolts. The second fixing seat is provided on the connecting line, and the mounting sleeve is fixedly connected to the second fixing seat. The first fixing seat is slidably provided on the second fixing seat and is fixedly connected to the second interface. The second fixing seat is threadedly provided with bolts, and the first fixing seat is threadedly connected to two bolts. Magnets are embedded in both the mounting sleeve and the first fixing seat, and the two magnets attract each other.

[0008] Preferably, the device also includes a detector and an alarm. The second interface is equipped with a detector and four alarms, and the detector and the alarms are electrically connected.

[0009] Preferably, a pressing block is fixedly connected to the connecting plate.

[0010] Preferably, the card block is in the shape of a rhombus or cone.

[0011] Preferably, the first interface has two mounting holes.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By pushing the second interface into the first interface, the plug block then squeezes the locking block to move. The locking block drives the two sliding plates and the connecting plate to move downward to squeeze the elastic member. When the locking block aligns with the opening on the plug block, the elastic member rebounds and drives the locking block to move upward and lock into the plug block, thereby locking the first interface and the second interface, preventing the interface from loosening or falling off due to accidental contact or other external forces, and ensuring the safety and stability of the charging process.

[0013] 2. By unscrewing the bolts and pulling the second interface outward, the magnet on the second interface will disengage from the magnet on the mounting sleeve. This allows for the replacement of the corresponding interface as needed, thereby increasing applicability.

[0014] 3. The detector detects abnormalities such as voltage, overcurrent, excessive temperature, or poor connection. When an abnormality is detected, the control module inside the detector activates the alarm and issues an alarm to remind users and relevant personnel to pay attention to potential safety risks and take corresponding measures to avoid accidents.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1: A quick-change interface for electric vehicle batteries to prevent mis-insertion, see reference. Figures 1-8 As shown, it includes a first interface 1, a protective cover 2, a second interface 3, and a connecting line 4. The protective cover 2 is hinged to the first interface 1, and the connecting line 4 is provided on the second interface 3. The groove of the first interface 1 and the connector of the second interface 3 are polygonal, allowing insertion in only one direction to prevent misinsertion. It also includes a plug block 5, a mounting base 6, a guide rod 7, a sliding plate 8, a locking block 9, an elastic element 10, a connecting plate 11, and a protective shell 12. The plug block 5 is provided at the bottom of the first interface 1, and the protective shell 12 is provided on the second interface 3. The interface 3 is provided with a mounting base 6. The left and right sides of the mounting base 6 are provided with guide rods 7 by welding. The guide rods 7 are located inside the protective shell 12. The protective shell 12 is provided with a sliding connecting plate 11. The connecting plate 11 slides on the two guide rods 7. The guide rods 7 are fitted with elastic elements 10. The two ends of the elastic elements 10 are connected to the guide rods 7 and the connecting plate 11 respectively. The lower part of the connecting plate 11 is provided with two sliding plates 8 by welding. The two sliding plates 8 are provided with a locking block 9 by welding. The locking block 9 is locked into the mounting base 6.

[0026] See Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a pressing block is fixedly connected to the connecting plate 11.

[0027] See Figure 4 and Figure 5 As shown, the card block 9 is a rhomboid shape, which facilitates the insertion block 5 to press the card block 9.

[0028] See Figures 1-3 As shown, the first interface 1 has two mounting holes to facilitate the installation of the device on an electric vehicle.

[0029] When this device is needed, first install the first interface 1 on the electric vehicle battery. When charging the electric vehicle, unscrew the protective cover 2 and push the second interface 3 into the first interface 1. The insert block 5 then presses the locking block 9 downwards. The locking block 9 drives the two sliding plates 8 and the connecting plate 11 downwards. The connecting plate 11 moves downwards and presses the elastic element 10, which is then compressed. When the locking block 9 aligns with the opening on the insert block 5, the elastic element 10 rebounds and drives the locking block 9 upwards to lock into the insert block 5, thereby locking the first interface 1 and the second interface 3 to prevent the interface from loosening or falling off due to accidental contact or other external forces, thus ensuring the safety and stability of the charging process. As the locking block 9 moves upwards, it drives the two sliding plates 8 and the connecting plate 11 to reset. After charging is completed, press the pressing block to drive the connecting plate 11, the locking block 9, and the two sliding plates 8 downwards, then pull out the second interface 3, and finally release the pressing block.

[0030] Example 2: Based on Example 1, refer to Figure 1 , Figure 6 and Figure 7 As shown, it also includes a mounting sleeve 13, a magnet 14, a first fixing seat 15, a second fixing seat 16, and bolts 17. The second fixing seat 16 is provided on the connecting line 4. The mounting sleeve 13 is fixedly connected to the left side of the second fixing seat 16. The first fixing seat 15 is slidably provided on the second fixing seat 16. The first fixing seat 15 is fixedly connected to the second interface 3. The bolts 17 are threaded on the second fixing seat 16. The first fixing seat 15 is threadedly connected to the two bolts 17. Magnets 14 are embedded in both the mounting sleeve 13 and the first fixing seat 15. The two magnets 14 attract each other.

[0031] When the second interface 3 needs to be replaced, unscrew the bolt 17 and pull the second interface 3 outward to disengage the magnet 14 on the second interface 3 from the magnet 14 on the mounting sleeve 13. This allows for the replacement of the corresponding interface as needed, thereby increasing applicability. Then, insert the new connector into the second fixing seat 16 so that the magnet 14 on the second interface 3 engages with the magnet 14 on the mounting sleeve 13. Finally, use the bolt 17 to install the first fixing seat 15 and the second fixing seat 16 together.

[0032] See Figure 1 and Figure 8 As shown, it also includes a detector 18 and an alarm 19. The detector 18 is installed on the second interface 3 by means of bolt connection. The alarm 19 is symmetrically installed on the front and rear sides of the right side of the second interface 3. The detector 18 contains a control module and the detector 18 is electrically connected to the alarm 19.

[0033] During charging, the detector 18 detects abnormalities such as voltage, overcurrent, excessive temperature, or poor connection. When an abnormality is detected, the control module inside the detector 18 activates the alarm 19 and issues an alarm to remind users and relevant personnel to pay attention to potential safety risks and take corresponding measures to avoid accidents.
