[0033] As shown in Figures 1 to 3 A vehicle-mounted battery replacement system, comprising a battery compartment 1 and a battery replacement robot 3, the battery compartment 1 is semi-enclosed to form a cavity for accommodating a battery pack 4, and the cavity is provided with a pin lock seat 2 on both sides of the insertion end, the pin lock seat 2 is provided with a lock shell 201 and an unlocking push plate 205 rotating relative to the pin lock seat 2, the lock shell 201 is provided with a lock tongue 202, the lock tongue 202 is provided with an insertion site 2021 for accommodating the mounting shaft 401 of the battery pack 4 and allowing the lock tongue 202 to rotate relative to the lock shell 201, a spring plate 203 for stopping the mounting shaft 401 is correspondingly clamped below the lock tongue 202, a pull plate 204 is arranged between the spring plate 203 and the unlocking push plate 205, the unlocking push plate 205 is arranged obliquely, the battery replacement robot 3 comprises an unlocking push rod 301 arranged corresponding to the unlocking push plate 205, the unlocking push rod 301 is used to push the unlocking push plate 205 to rotate, so that the pull plate 204 drives the spring plate 203 to rotate to an unlocking position avoiding the lock tongue 202. This unlocking method not only effectively solves the maintainability of the battery pack 4 and the operability of the battery pack 4, but also is simple and fast, improves the replacement efficiency and the maintainability and operability of the product.

[0034] Specifically, as shown in Figures 2 to 5As shown, a first locking member 2022 is provided on one side of the insertion position 2021, and a second locking member 2023 is provided on the other side of the insertion position 2021. The end of the spring piece 203 is bent upward to form a locking position 2031. The first locking member 2022 and the second locking member 2023 are both connected to the locking position 2031. The lock housing 201 is provided with a mounting hole 2016. The end of the spring piece 203 is connected to a first pin 206. The upper end of the unlocking push plate 205 is connected to a second pin 207. The first pin 206 passes through the mounting hole 2016 and the pin lock seat 2 in sequence and is connected to one end of the pull plate 204. The second pin 207 passes through the pin lock seat 2 and is connected to the other end of the pull plate 204.

[0035] Under normal conditions, the second locking component 2023 is engaged with the locking position 2031. When the unlocking push rod 301 is engaged... Figure 4 When the push rod 301 is pushed towards the unlocking push plate 205 and comes into contact with the inclined surface of the unlocking push plate 205, the lower end of the unlocking push plate 205 will rotate upward in the pushing direction, and the upper end of the unlocking push plate 205 will rotate downward in the opposite direction. At the same time, it will drive the pull plate 204 and the first pin 206 to move downward accordingly. Since the diameter of the mounting hole 2016 is larger than the diameter of the first pin 206, the first pin 206 can achieve a downward rotation trajectory in the mounting hole 2016, so that the end of the spring piece 203 rotates downward accordingly. The second locking piece 2023 separates from the locking position 2031, exposing the insertion position 2021 to facilitate the pushing of the mounting shaft 401. During the process of pushing the mounting shaft 401 in, the locking tongue 202 will drive the locking tongue 202 to rotate towards the inside of the lock shell 201, so that the insertion position 2021 faces downward. When the unlocking push rod 301 is pushed in as shown, Figure 5 When the spring 203 moves in the opposite direction to the unlocking push plate 205 and separates from the inclined surface of the unlocking push plate 205, it will rebound and drive the unlocking push plate 205 and the pull plate 204 to rotate upward and reset, so that the first locking piece 2022 is locked on the locking position 2031, thereby locking and fixing the mounting shaft 401.

[0036] like Figures 6 to 7 As shown, the lock housing 201 partially surrounds an opening 2011. The lock tongue 202 and the spring piece 203 are rotatably connected within the opening 2011. An insertion port 2012 is provided on one side of the opening 2011, and a guide position 2013 is provided on the other side of the opening 2011. A rubber pad 2015 is provided at one end of the guide position 2013, and the other end of the guide position 2013 extends outward to form a slope 2014. When the mounting shaft 401 pushes into the lock tongue 202, it is inserted from the insertion port 2012 through the insertion position 2021 into the slope 2014, and then enters the guide position 2013 along the slope 2014. The rubber pad 2015 is used to buffer the impact force generated when the mounting shaft 401 moves.

[0037] The battery compartment 1 comprises a chassis 101, the chassis 101 is provided with a limiting plate 102 at the end, the limiting plate 102 is provided with a charging position 1021 at the upper end, the limiting plate 102 is provided with a limiting frame 103 at both sides, a plurality of rollers 1031 are rotatably connected to the inner side of the limiting frame 103, and a plurality of rolling rollers 1011 are rotatably connected to the chassis 101; the rollers 1031 and the rolling rollers 1011 all play a role in reducing friction, which can greatly reduce the force required when moving the battery pack 4, and make the movement more labor-saving.

[0038] As shown in Figure 8 The battery pack 4 is connected with the battery changing robot 3, and the battery changing robot 3 is provided with a first connecting piece 304 at one end and a second connecting piece 305 at the other end; the battery pack 4 is provided with an L-shaped plate welded at the upper end and the lower end; when the battery changing robot 3 is connected with the battery pack 4, the first connecting piece 304 is inserted into the L-shaped plate at the upper end of the battery pack 4 from below, and the second connecting piece 305 is inserted into the L-shaped plate at the lower end of the battery pack 4 from above, so that the battery changing robot 3 can drive the battery pack 4 to perform a pushing and pulling operation.

[0039] The working process of the vehicle-mounted battery changing system is that the battery pack 4 is pushed into the cavity by the battery changing robot 3, so that the unlocking push rod 301 touches the unlocking push plate 205, the spring plate 203 is separated from the lock tongue 202, and the mounting shaft 401 can be smoothly pushed into the insertion position 2021; after the mounting shaft 401 is pushed into the insertion position 2021, the battery changing robot 3 is unlocked with the battery pack 4, the battery changing robot 3 and the unlocking push rod 301 are away from the battery pack 4 while the battery pack 4 remains stationary, so that the spring plate 203 is bounced back to the locking position and is clamped with the lock tongue 202, the battery pack 4 is kept in a locked state, and the battery pack 4 is charged through the charging position 1021.
