Technical Field

[0001] The utility model relates to the field of power exchange cabinets, and in particular to a self-locking and anti-falling battery charging connector for power exchange cabinets. Background Art

[0002] A battery swap cabinet is a device used to replace batteries in electric vehicles. Its main function is to provide convenient battery replacement services to solve the problem of insufficient power in electric vehicles during driving. Battery swap cabinets are usually set up in various traffic arteries or popular areas in the city. Users can quickly replace batteries through battery swap cabinets, extend the range of electric vehicles, and improve travel efficiency.

[0003] The existing battery charging connector of the battery swap cabinet is to place the battery on the battery swap cabinet and then insert the plug into the battery charging interface. Since the battery swap cabinet is subjected to vibration or impact during movement or transportation, the battery charging connector may fall off, causing the battery to short-circuit or cause other safety hazards during charging, which is very inconvenient.

[0004] Therefore, it is necessary to design a self-locking and anti-falling battery charging connector for the battery swap cabinet that can self-lock the plug, reduce the risk of the plug accidentally falling off, and avoid short circuits or other safety hazards during the charging process. Summary of the invention

[0005] In order to overcome the disadvantages of the existing battery charging connector of the battery swap cabinet, which may cause the battery charging connector to fall off, causing the battery to short-circuit or cause other safety hazards during the charging process, which is quite inconvenient. The utility model provides a self-locking and anti-falling battery charging connector for the battery swap cabinet that can self-lock the plug, reduce the risk of accidental falling off of the plug, and avoid short circuit or other safety hazards during the charging process.

[0006] The technical solution of the utility model is: a self-locking and anti-falling battery charging connector for a battery swap cabinet, comprising a battery swap cabinet, a revolving door, a battery, a charging interface, a plug and a self-locking mechanism. The revolving door is rotatably connected to the front left side of the battery swap cabinet, a battery is placed inside the battery swap cabinet, a charging interface is connected to the upper middle side of the battery, a plug is carded on the charging interface, the plug is connected to the battery swap cabinet, and a self-locking mechanism is provided on the battery swap cabinet.

[0007] As a preferred technical solution of the utility model, a handle is provided on the front side of the revolving door.

[0008] As a preferred technical solution of the utility model, the self-locking mechanism includes a mounting seat, a sleeve, a limiting frame, a first telescopic spring and a locking frame.

[0009] As a preferred technical solution of the utility model, the front side of the limiting frame is an inclined surface.

[0010] As a preferred technical solution of the utility model, it also includes a protective mechanism, which includes a protective cover, a guide frame and a second telescopic spring. The protective cover is slidably connected to the locking frame, and the bottom of the protective cover is in contact with the charging port. The upper sides of the front and rear parts of the locking frame are connected to guide frames, and the guide frames are slidably connected to the protective cover. A second telescopic spring is connected between the guide frames and the protective cover.

[0011] As a preferred technical solution of the utility model, a limit block is provided on the lower side of the guide frame.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] A self-locking and anti-dropping battery charging connector for a power exchange cabinet, such as Figure 1 and Figure 2 As shown, it includes a battery swap cabinet 1, a revolving door 2, a battery 3, a charging interface 4, a plug 5 and a self-locking mechanism 6. The revolving door 2 is rotatably connected to the front left side of the battery swap cabinet 1. A handle is provided on the front side of the revolving door 2 for easy gripping of the revolving door 2. A battery 3 is placed inside the battery swap cabinet 1. The charging interface 4 is connected to the upper middle side of the battery 3. The plug 5 is clamped on the charging interface 4. The plug 5 is connected to the battery swap cabinet 1. The battery swap cabinet 1 is provided with a self-locking mechanism 6 that can self-lock the plug 5.

[0021] like Figure 2 and Figure 3 As shown, the self-locking mechanism 6 includes a mounting seat 61, a sleeve 62, a limiting frame 63, a first telescopic spring 64 and a locking frame 65. The mounting seat 61 is connected to the rear side of the power exchange cabinet 1, and the front sides of the left and right parts of the mounting seat 61 are connected to the sleeve 62. The inside of the sleeve 62 is slidably connected with the limiting frame 63, and the front side of the limiting frame 63 is an inclined surface. The first telescopic spring 64 is connected between the limiting frame 63 and the adjacent sleeve 62. The locking frame 65 is connected to the lower part of the plug 5, and the limiting frame 63 is clamped with the locking frame 65, and the limiting frame is squeezed together with the locking frame.

[0022] like Figure 2 and Figure 4 As shown, a protective mechanism 7 is also included, and the protective mechanism 7 includes a protective cover 71, a guide frame 72 and a second telescopic spring 73. The protective cover 71 is slidably connected to the locking frame 65, and the protective cover 71 is in contact with the charging interface 4. The upper sides of the front and rear parts of the locking frame 65 are connected to the guide frames 72, and the lower sides of the guide frames 72 are provided with limit blocks for easy positioning. The guide frames 72 are slidably connected to the protective covers 71, and a second telescopic spring 73 is connected between the guide frames 72 and the protective covers 71.

[0023] When using the device, first place the battery swap cabinet 1 in the charging area of ​​the battery 3, then hold the handle to open the revolving door 2, then place the battery 3 on the battery swap cabinet 1, and then insert the plug 5 into the charging port 4, so that the locking frame 65 contacts the limiting frame 63, the limiting frame 63 moves backward on the sleeve 62, and the first telescopic spring 64 is squeezed and contracted. When the plug 5 is connected to the charging port 4, the limiting frame 63 moves forward on the sleeve 62, and the first telescopic spring 64 is restored, so that the limiting frame 63 is connected to the locking frame 65, so that the plug 5 can be self-locked, reducing the risk of accidental detachment of the plug 5 and avoiding short circuits or other safety hazards during charging. When the plug 5 is inserted into the charging interface 4, the protective cover 71 contacts the charging interface 4. Under the action of the second telescopic spring 73, the protective cover 71 fits tightly against the charging interface 4, thereby preventing dust from entering the charging interface 4, reducing pollution and corrosion inside the charging interface 4, and extending the service life of the charging interface 4. When the battery 3 needs to be taken out, the plug 5 can be moved upward, driving the locking frame 65 to move upward, so that the limiting frame 63 moves forward and backward, and the first telescopic spring 64 shrinks and rebounds, so that the limiting frame 63 no longer contacts the locking frame 65, and the protective cover 71 no longer contacts the charging interface 4, thereby making the plug 5 detach from the charging interface 4, and then the battery 3 can be taken out.
