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] A magnetic battery pack assembly includes a battery pack 1 and an external connector. The outer shell of the battery pack 1 is a plastic shell. One end of the battery pack 1 is fixedly connected to a top end cover 3. A breaking notch 4 is provided on the outer shell of the battery pack 1. The breaking notch 4 is used to form a compression area 101 that can be compressed and deformed on the outer shell of the battery pack 1. A clamping block 5 is fixedly connected to the top of the compression area 101. One side of the clamping block 5 is arranged at an angle, and a clamping groove 102 is formed between the vertical side of the clamping block 5 and the top end cover 3.

[0026] The external connecting part includes an external sleeve 6, one end of the external sleeve 6 is fixedly connected to a connecting sleeve 7, the inner wall of the connecting sleeve 7 is fixedly connected to a positioning block 8, the positioning block 8 is adapted to the clamping groove 102, a groove is provided on the top end cover 3, and a clamping plate 9 is fixedly connected to one end of the compression area 101 and located in the groove of the top end cover 3.

[0027] like Figure 1 and Figure 2 There is an arc on the surface of the clamping plate 9, which increases the friction force on the surface of the clamping plate 9. The separating notch 4 also forms a gap at the bottom of the clamping plate 9, so that the clamping plate 9 and the compression area 101 can be pressed downward. The plastic shell of the battery pack 1 has a certain toughness, so that the compression area 101 can recover quickly after being compressed and deformed.

[0028] The outer casing 6 is provided with a ventilation slot 10 , which is used to improve the ventilation and heat dissipation capability of the battery pack 1 when it is located inside the outer casing 6 .

[0029] like Figure 1 and Figure 4 By utilizing the ventilation slots 10 , when the battery pack 1 is located in the outer casing 6 , the outer casing 6 will not be in a closed state, and airflow can interact inside and outside the outer casing 6 , thereby improving the heat dissipation capacity of the battery pack 1 .

[0030] A first magnetic cover 11 is fixedly connected to the outer shell 6 , and a first magnet 12 is fixedly connected to one side of the first magnetic cover 11 .

[0031] An alloy reinforcement frame 13 in a ring array is fixedly connected to the outer shell 6 , an elastic protective gasket 14 is fixedly connected to the alloy reinforcement frame 13 , and a disconnection port 15 is provided on the alloy reinforcement frame 13 and below the venting slot 10 .

[0032] like Figure 4 and Figure 5 There are raised portions 21 on both sides of the alloy reinforcement frame 13, which are embedded in the interior of the outer shell 6, so that the alloy reinforcement frame 13 is more stable when fixed in the outer shell 6, and the disconnect port 15 is connected to the ventilation slot 10, so that external air can better enter the interior of the outer shell 6.

[0033] The outer surface of the alloy reinforcement frame 13 is fixedly connected to the inner surface of the outer shell 6 , and the inner wall of the reinforcement frame 13 is provided with a plurality of arc-shaped recesses 16 .

[0034] like Figure 4 and Figure 5 The alloy reinforcement frame 13 can enhance the compressive resistance of the outer casing 6, so that the outer casing 6 can provide better protection for the battery pack 1. The battery pack 1 passes through the alloy reinforcement frame 13, and the alloy reinforcement frame 13 uses the elastic protection gasket 14 as the contact surface with the battery pack 1, which can better provide protection for the battery pack 1.

[0035] A second magnetic cover 17 is provided at one end of the battery pack 1, and a second magnet 18 and a magnetic frame 19 are provided between the second magnetic cover 17 and the battery pack 1. A locking screw 20 is provided on the second magnetic cover 17, and one end of the locking screw 20 passes through the second magnetic cover 17 and the magnetic frame 19 in sequence and is threadedly connected to the battery pack 1, so as to fix the second magnetic cover 17 and the magnetic frame 19 to the inside of the battery pack 1.

[0036] like Figure 1 and Figure 2 There is a screw hole on the inside of the battery pack 1 to realize the threaded connection with the locking screw 20 to fix the second magnetic cover 17 and the magnetic frame 19. The second magnetic cover 17 and the magnetic frame 19 are located on both sides of the second magnet 18, and the second magnet 18 can be fixed in the battery pack 1 between the second magnetic cover 17 and the magnetic frame 19.

[0037] The working principle of the magnetic battery pack assembly provided by this utility model is as follows:

[0038] When one end of the battery pack 1 is inserted into the external connector, the battery pack 1 passes through the alloy reinforcement frame 13, and the first magnet 12 and the second magnet 18 are adsorbed together. In this process, the protrusion 21 squeezes the inclined surface on the top of the clamping block 5, squeezing the clamping block 5 into the inside of the battery pack 1, causing the compression area 101 to deform downward, and the positioning block 8 moves into the clamping groove 102. At this time, the compression area 101 is reset, clamping the positioning block 8 in the clamping groove 102, so that the battery pack 1 and the external shell 6 cannot be separated.

[0039] When the clamping plate 9 is manually pressed, the clamping plate 9 can drive the compression area 101 to deform downward, and the clamping block 5 moves downward accordingly. At this time, the clamping block 5 will not be pressed against one side of the positioning block 8, and the battery pack 1 can be taken out of the outer shell 6, so that the positioning block 8 and the clamping groove 102 are separated.

[0040] Compared with related technologies, the magnetic battery pack assembly provided by the present invention has the following beneficial effects:

[0041] The present invention can achieve magnetic adsorption by cooperating with the first magnet 12 and the second magnet 18 when the battery pack 1 is connected to the external connector, and can also enable the positioning block 8 to move into the clamping groove 102 to clamp the battery pack 1. The battery pack 1 is more stable in the external connector, and the battery pack 1 will not be thrown out when the external connector moves, thereby improving the safety of the battery pack 1. At the same time, by pressing the clamping plate 9, the battery pack 1 can be quickly removed from the external casing 6. The operation is simple, and the installation and removal of the battery pack 1 are convenient.
